[[User:Codename Noreste|Codename Noreste]] ([[User talk:Codename Noreste|discuss]] • [[Special:Contributions/Codename Noreste|contribs]]) 23:20, 17 April 2026 (UTC)''</div> I would like to propose the following retitles should a user be nominated for any of the following user rights: * Curator: Candidates for Curatorship * Bureaucrat: Candidates for Bureaucratship The reason is that many curator (and probably bureaucrat) requests have run solely under {{tq|Candidates for Custodianship}}, but that title might sound misleading (especially in regards to the permission a user is requesting). CheckUser and Oversight (suppressor) are not included above since no user was nominated for these sensitive permissions, probably. [[User:Codename Noreste|Codename Noreste]] ([[User talk:Codename Noreste|discuss]] • [[Special:Contributions/Codename Noreste|contribs]]) 01:30, 19 March 2026 (UTC) :And it's not that when someone at the beginning misplaced the request, no one thought to move it and the others copied it. Even today, it would be possible to simply take it all and move it. Otherwise, for me, the more fundamental problem is that there is [[Wikiversity:Curators|no approved policy for curators]] than where the requests are based. Curators then operate in a certain vacuum and if one of them "breaks out of the chain", the average user doesn't have many transparent tools to deal with it, because there is no policy.

It seems [https://openeducation.nz/terminating-oer-foundation their foundation has closed] and they are no longer operating. They had done quite a bit of outreach (e.g., in the Pacific and Africa) to get educators using wiki. The WikiEducator content is still available in MediaWiki - and potentially could be imported to Wikiversity ([https://wikieducator.org/WikiEducator:Copyrights CC-BY-SA] is the default license).

And I would be interested to see how Wikiversity is doing in the monitored metrics. We probably have more editors than Wikinews had, but what about consumers and achieving the goals? [[User:Juandev|Juandev]] ([[User talk:Juandev|discuss]] • [[Special:Contributions/Juandev|contribs]]) 19:14, 1 April 2026 (UTC) :Wikiversity's biggest issue in recent times was the hosting of low-quality, trash content. Thankfully we've done a great job in removing pseudoscience and other embarrassingly trash content (Wikidebates, for example), but the biggest concern moving forward is proper maintenance IMO. I've caught several pseudoscience pages being created within the last few months that could easily have flown under the radar (ex, [[The Kelemen Dilemma: Causal Collapse and Axiomatic Instability]]), so I'd urge our custodians/curators to be on the lookout for this type of content. Usually an AI-overview can point this type of content out relatively well. :In terms of visibility, I believe Wikiversity is a high-traffic project. I remember my [[Mathematical Properties]] showing up on the first page of Google when searching up "math properties" for the longest time (and is still showing up in the first page 'till this day!). Besides, Wikinews hosted a lot of short-term content (the nature of news articles), while Wikiversity hosts content that can still be useful a decade later (ex, [[A Reader's Guide to Annotation]]). :I think we are on a better path than we were a few months ago, and I do want to thank everyone here who has been helping out with maintaining our website! —[[User:Atcovi|Atcovi]] [[User talk:Atcovi|(Talk]] - [[Special:Contributions/Atcovi|Contribs)]] 20:48, 1 April 2026 (UTC) :For what it's worth, the group that did that study has since disbanded, so no one is monitoring the other sister projects in the same way. Additionally, Wikinews had some catastrophic server issues due to the maintenance of [[:m:Extension:DynamicPageList]] which don't apply here. Your questions are still worth addressing, but I just wanted to cut off any concern at the pass about Wikiversity being in the same precarious situation. Wikiversity is definitely the biggest "lagging behind" or "failure" project now that Wikinews is being shuttered, but I don't see any near- or medium-term pathway to closing Wikiversity. —[[User:Koavf|Justin (<span style="color:grey">ko'''a'''vf</span>)]]<span style="color:red">❤[[User talk:Koavf|T]]☮[[Special:Contributions/Koavf|C]]☺[[Special:Emailuser/Koavf|M]]☯</span> 00:46, 2 April 2026 (UTC) :[[w:en:Wikipedia:Wikipedia Signpost/2026-03-31/News and notes|Entirety of Wikinews to be shut down]] (Wikipedia Signpost) -- [[User:Jtneill|Jtneill]] - <small>[[User talk:Jtneill|Talk]] - [[Special:Contributions/Jtneill|c]]</small> 02:03, 11 April 2026 (UTC) == Action Required: Update templates/modules for electoral maps (Migrating from P1846 to P14226) == Hello everyone, This is a notice regarding an ongoing data migration on Wikidata that may affect your election-related templates and Lua modules (such as <code>Module:Itemgroup/list</code>). '''The Change:'''<br /> Currently, many templates pull electoral maps from Wikidata using the property [[:d:Property:P1846|P1846]], combined with the qualifier [[:d:Property:P180|P180]]: [[:d:Q19571328|Q19571328]].

'''Deadline:'''<br /> We are temporarily retaining the old data on [[:d:Property:P1846|P1846]] to allow for a smooth transition. However, to complete the data cleanup on Wikidata, the old [[:d:Property:P1846|P1846]] statements will be removed after '''May 1, 2026'''. Please update your modules and templates before this date to prevent any disruption to your wiki's election articles. Let us know if you have any questions or need assistance with the query logic.

What I've called it so far is "The Neurodiversity-inspired Idea". At other times I used more sensationalist wording but here on Wikiversity I don't dare do that. I actually woke up with thinking about putting this into my userspace draft: "Personal Observations Made By Meeting Autistic and Non-Autistic Adults". My ultimate goal is to stop blathering about my "idea" to friend and family without feeling my "methodology" is going into any progressive direction whatsoever. My latest encounter was somewhat constructive though. A friend of a friend who worked with people presenting ideas in attempting to getting grants. I don't want a grant. I just want to figure out how I can express my "idea" in a way so that I can more clearly figure out what flaws it got. At the same time I tend to overthink. If anyone thinks etherpad might be a good place and considering Wikimedia already got an etherpad at https://etherpad.wikimedia.org/ if anyone feels like they know me better in the future feel free to suggest a "session" on etherpad. '''If I don't receive a reply to this in 1 week's time I will begin to explore this "idea" into my userspace''' unless you replied and refrained me from doing so, of course. Then maybe after "developing it there" I might reference it to you another future time here in the Colloquium, with my "idea" still in my userspace draft. This "idea" is sort of a burden, I'm happy I've made the choice to get rid of it and hopefully move on with my life, unless there is something to this "idea". My failure is probably evident: I feel I haven't told you anything. Same happened to when I talked to friends and family. In danger of overthinking it further I'll publish this right now.

I'd say go for it (no need to wait), give birth to your idea and share about it here and elsewhere. Let it take shape and see where it might go. In many ways, this is exactly what an open collaborative learning community should be doing. Others might not know well how to respond, so perhaps consider creating some questions to accompany the idea.

I concluded that since I've not yet developed a methodology that adheres to "Do no harm" and this is my first time working my "idea" into a way that is compatible with how projects develop on English Wikiversity this is new to me. My methodology isn't developed and therefore trying to get attention to my project through a name can wait. Yesterday I figured out a silly title that has nothing to do with the project: "Planetary Awareness Potato Cabbage Rolls" or something like that. Google output read that no such thing exists so I wanted it mainly to be unique.

Is there anyone here who is interested for Neurodiversity to be "something more" than it already is? Does anyone here consider Neurodiversity one of the "harder topics" to work on or discuss? Does anyone here have an opinion about the [[Neurodiversity Movement]]? So these questions don't appear like "out of a vacuum" I can tell you a bit about my background: Many years ago I got a psychiatric diagnosis "Asperger's". After I stepped out of the office and my Äsperger's was 'concluded', I stepped out into the street and thought my first negative thought(but the positive thought followed after). The thought was about concentration camps in the second world war and that the world seemed to be going into the direction of "labeling others". I was unsure whether this was "real science" and sort of "challenged myself" to make up my own mind after meeting people that had been given this diagnosis. The more adults with this diagnosis I met the more I started seeing "patterns". Was it a coincidence that the first person with Asperger's I met reminded me about my father later after I had plenty of times of experience with interacting with him? None of the people I interacted with online through IRC text chat...I felt I got any clue about how "their brains work". Only when I met one person from the Asperger's chat community in person we both realized that whatever we experienced was akin to the "chaos theory". He told me about "chaos theory" while I didn't know even what that term meant but I guess I 'read between the lines'. My question that I linger on still today is "did he understand about me what I think I understood about him?"? That our brains had the same configuration? Most autistic adults who meet other autistic adults usually get disappointed. They think the diagnosis will help them meet somebody like themselves and then they realize the great diversity in the autistic spectrum created by Psychiatry. I later stopped interacting with autistic communities that much, I felt that it did not benefit me. Also Neurodiversity's "neurotypes" interested me for a while until I realized I had "misunderstood everything" about them and how they are used in the Neurodiversity Movement or "Neurodiversity community" if that even can precisely be defined? I doubt it but if you want to contribute to the [[Neurodiversity Movement]]. My previous attempts failed as I got more and more confused. I think a community project needs a community. With a lack of that I don't think it is worth my time. If any of you would like to work on that project let me know on my talk page. So I was kinda lost and was talking to my friend and psychologist and I realized if I never talk about my idea to anyone in a "comprehensive way" or show that it matters to me nothing is going to ever happen. So I started talking about my "idea" more. Nobody could understand the "idea" because I had not developed my skills regarding where to start...although the process had already started "automatically" and that's why I often think of "well my brain sort of activated me". I don't feel like I did have a plan and this idea happened. It happened "by itself". My brain reacted to what I was seeing in a video or stream. I value interaction highly in this idea. I think it would be helpful to make a community of people who are not paranoid about stuff that can express itself like "don't analyze me!", "don't compare me to anyone!". On the contrary, more often than not those adults who were diagnosed were actually openly comparing themselves with each other and I think that is healthy in a "science" way if done the "right way" which probably means "Do no harm". I found video material is important but I'm very unsure if uploading own video material to Wikimedia Commons would constitute a "reasonable" use of the resources there. Maybe somebody here needs to ask more questions to me that I should answer before that happens. I also know the '''be bold''' so I could just do what I think might be ok. Though I work better in a group as long as I know what "group configurations" help me. This is in a non-profit way. Since the state supported me this might be a way I am trying to "give back" to the state and "the world". May seem overly ambitious and crazy but this thing gives me energy. It gives me hope when trying to develop this idea.

Another was the lack of activity, which can be ameliorated by having it be part of an existing project instead of its own domain (e.g. some editions of Wikipedia host their own Wikinews already and those projects were not impacted by the closure). :* Are any changes to the scope of Wikinews proposed? ::*Not at this juncture. I would also propose as far as implemention goes that we would request a new namespace and that the material be more-or-less sequestered into its own ongoing project, like Wikijournal is or like the Cookbook and Wikijunior are at our sister [[:b:]]. :* How does [[Wikinews]] fit with the [[Wikiversity:Mission]]? What aligns well? Where might there be tension? :** e.g., I'm not sure that a page like [[Story/Manchester City moves two points behind Arsenal]] in and of itself will serve as an educational resource. ::*The process of citizen journalists practicing their craft in real-time and collaborating with others to do so is itself an education activity. We would essentially be hosting a real-time experiment in citizen journalism, online communities, and collaborative learning in addition to the prospect of spreading educational information from someone actually reading the news. I would propose that we could also make a more deliberate attempt to engage with learning <em>about</em> what does and doesn't work with collaborative news writing by experimentation (e.g. audio news, syndicating to other sites, incorporating freely-licensed news from other sources, writing hyper-local news, writing briefs versus longer-term reportage) and also seeing if the problems noted in the Task Force report that recommended closure can be overcome. Note that we have already done some local investigation about and learning about wiki-based journalism on Wikinews here at [[Journalism studies and Wikinews]]. We could continue that learning and refine the process, including incorporating journalism students from universities. As for tensions, Wikinews is the only sister project that must be done with a quick turn-around: if you take a long time to [[:s:|transcribe a book]], that's just how long it takes, but if you take a long time to write news, it ceases to be news entirely. Wikiversity has been a very slow-growing project that has definitely had some successes but has generally come together over a long period with most learning resources being individual passion projects (or sometimes, frankly, crankery) which would not work with collaborative news that requires more than just a single editor writing whatever he feels like. ::Please let me know any other questions/concerns and any other editors feel free to give your own perspective. ―[[User:Koavf|Justin (<span style="color:grey">ko'''a'''<span style="color:black">v</span>f</span>)]]<span style="color:red">❤[[User talk:Koavf|T]]☮[[Special:Contributions/Koavf|C]]☺[[Special:Emailuser/Koavf|M]]☯</span> 06:13, 14 May 2026 (UTC) :::Thanks, Justin — it is food for thought. :::In attempting to understand how we've arrived here, I've summarised some of the background on this page: [[Wikinews]]. :::Perhaps it could be helpful to flesh out more of the vision / ideas / possibilities / challenges on that page? -- [[User:Jtneill|Jtneill]] - <small>[[User talk:Jtneill|Talk]] - [[Special:Contributions/Jtneill|c]]</small> 11:49, 14 May 2026 (UTC) :::*Having given it some thought, in principle, I support hosting [[citizen journalism]] on Wikiversity where it is clearly connected to a learning project and/or constitutes original research, both of which align strongly with [[Wikiversity:Mission|Wikiversity’s educational mission]]. :::*My chief concern is the potential for news content that is not clearly linked to the purpose of Wikiversity. To avoid this, some community-agreed guidelines would be prudent. These need not be overly restrictive; they should support boldness and experimentation while helping ensure alignment with Wikiversity's purpose. :::*Given the reported low and declining activity on Wikinews, it seems unlikely that English Wikiversity would be overwhelmed by an influx of news-related editing. My impression is that English Wikinews was the most active edition, but even so, many contributors are likely to disperse to other projects or cease editing altogether. A modest migration of interested editors to Wikiversity seems manageable. :::*At this stage, I do not think a dedicated namespace is necessary. Subpages under [[Wikinews]] or nested pages under relevant learning or research projects, or user-space draft pages should be suitable. I agree that [[Wikijournal]] offers a useful model, as do several existing course structures on Wikiversity. :::*I support [[User:Koavf]]’s suggestions about framing Wikinews activity explicitly around learning. This would create a distinctive space for experimenting with collaborative news production in ways that are pedagogically meaningful. I agree that the [[journalism studies and Wikinews]] project developed by David and Leigh Blackall through the University of Wollongong is an excellent example of the intersection between Wikiversity and Wikinews. The [[Wikinews]] page could evolve into a hub for such projects. :::*I've tidied the [[:Category:Wikinews|Wikinews category]] and merged some content into the [[Wikinews]] page. As part of a reinvigoration effort, please review these and related resources such as [[:Category:Journalism]] and [[School:Journalism]]. :::*A further argument in favour of this initiative is that Wikipedia explicitly excludes both news reporting and original research. So, there is value in maintaining spaces within the Wikimedia ecosystem where these forms of knowledge production can be openly developed and curated. Such work can, in turn, generate valuable evidence and source material that may later inform Wikipedia articles. :::*The closure of WMF-hosted Wikinews does not imply that open wiki-based news curation lacks value. Indeed, the closure documentation appears supportive of experimentation with alternative news models across Wikimedia projects, including through Wikipedia and Wikidata. In that context, Wikiversity seems a natural home for a Wikinews experiment, provided it is clearly grounded in learning and/or research. :::-- [[User:Jtneill|Jtneill]] - <small>[[User talk:Jtneill|Talk]] - [[Special:Contributions/Jtneill|c]]</small> 11:39, 15 May 2026 (UTC) My understanding towards Wikinews' failure is that everything takes too long to be approved for the publish status, which means that any breaking news would have already become days-old stale news. Wikinews has a brand recognition (for right or wrong reasons) than Wikiversity and I wonder how effective Wikiversity can attract the "Wikinews refugees" to edit here.

[[User:Juandev|Juandev]] ([[User talk:Juandev|discuss]] • [[Special:Contributions/Juandev|contribs]]) 19:14, 1 April 2026 (UTC) :Wikiversity's biggest issue in recent times was the hosting of low-quality, trash content. Thankfully we've done a great job in removing pseudoscience and other embarrassingly trash content (Wikidebates, for example), but the biggest concern moving forward is proper maintenance IMO. I've caught several pseudoscience pages being created within the last few months that could easily have flown under the radar (ex, [[The Kelemen Dilemma: Causal Collapse and Axiomatic Instability]]), so I'd urge our custodians/curators to be on the lookout for this type of content. Usually an AI-overview can point this type of content out relatively well. :In terms of visibility, I believe Wikiversity is a high-traffic project. I remember my [[Mathematical Properties]] showing up on the first page of Google when searching up "math properties" for the longest time (and is still showing up in the first page 'till this day!). Besides, Wikinews hosted a lot of short-term content (the nature of news articles), while Wikiversity hosts content that can still be useful a decade later (ex, [[A Reader's Guide to Annotation]]). :I think we are on a better path than we were a few months ago, and I do want to thank everyone here who has been helping out with maintaining our website! —[[User:Atcovi|Atcovi]] [[User talk:Atcovi|(Talk]] - [[Special:Contributions/Atcovi|Contribs)]] 20:48, 1 April 2026 (UTC) :For what it's worth, the group that did that study has since disbanded, so no one is monitoring the other sister projects in the same way.

Your questions are still worth addressing, but I just wanted to cut off any concern at the pass about Wikiversity being in the same precarious situation.

'''What You Need To Do:'''<br /> To ensure your templates and infoboxes do not break or lose their maps, please update your local code to fetch data from [[:d:Property:P14226|P14226]] instead of the old [[:d:Property:P1846|P1846]] + [[:d:Property:P180|P180]] structure. A [[m:Wikidata/Property Migration: P1846 to P14226/List|list of pages]] was generated using Wikimedia Global Search. '''Deadline:'''<br /> We are temporarily retaining the old data on [[:d:Property:P1846|P1846]] to allow for a smooth transition. However, to complete the data cleanup on Wikidata, the old [[:d:Property:P1846|P1846]] statements will be removed after '''May 1, 2026'''. Please update your modules and templates before this date to prevent any disruption to your wiki's election articles. Let us know if you have any questions or need assistance with the query logic.

I actually woke up with thinking about putting this into my userspace draft: "Personal Observations Made By Meeting Autistic and Non-Autistic Adults". My ultimate goal is to stop blathering about my "idea" to friend and family without feeling my "methodology" is going into any progressive direction whatsoever. My latest encounter was somewhat constructive though. A friend of a friend who worked with people presenting ideas in attempting to getting grants. I don't want a grant. I just want to figure out how I can express my "idea" in a way so that I can more clearly figure out what flaws it got. At the same time I tend to overthink.

'''If I don't receive a reply to this in 1 week's time I will begin to explore this "idea" into my userspace''' unless you replied and refrained me from doing so, of course. Then maybe after "developing it there" I might reference it to you another future time here in the Colloquium, with my "idea" still in my userspace draft. This "idea" is sort of a burden, I'm happy I've made the choice to get rid of it and hopefully move on with my life, unless there is something to this "idea".

Is there anyone here who is interested for Neurodiversity to be "something more" than it already is? Does anyone here consider Neurodiversity one of the "harder topics" to work on or discuss? Does anyone here have an opinion about the [[Neurodiversity Movement]]? So these questions don't appear like "out of a vacuum" I can tell you a bit about my background: Many years ago I got a psychiatric diagnosis "Asperger's". After I stepped out of the office and my Äsperger's was 'concluded', I stepped out into the street and thought my first negative thought(but the positive thought followed after). The thought was about concentration camps in the second world war and that the world seemed to be going into the direction of "labeling others". I was unsure whether this was "real science" and sort of "challenged myself" to make up my own mind after meeting people that had been given this diagnosis. The more adults with this diagnosis I met the more I started seeing "patterns". Was it a coincidence that the first person with Asperger's I met reminded me about my father later after I had plenty of times of experience with interacting with him? None of the people I interacted with online through IRC text chat...I felt I got any clue about how "their brains work". Only when I met one person from the Asperger's chat community in person we both realized that whatever we experienced was akin to the "chaos theory". He told me about "chaos theory" while I didn't know even what that term meant but I guess I 'read between the lines'. My question that I linger on still today is "did he understand about me what I think I understood about him?"? That our brains had the same configuration? Most autistic adults who meet other autistic adults usually get disappointed. They think the diagnosis will help them meet somebody like themselves and then they realize the great diversity in the autistic spectrum created by Psychiatry. I later stopped interacting with autistic communities that much, I felt that it did not benefit me. Also Neurodiversity's "neurotypes" interested me for a while until I realized I had "misunderstood everything" about them and how they are used in the Neurodiversity Movement or "Neurodiversity community" if that even can precisely be defined? I doubt it but if you want to contribute to the [[Neurodiversity Movement]]. My previous attempts failed as I got more and more confused. I think a community project needs a community. With a lack of that I don't think it is worth my time. If any of you would like to work on that project let me know on my talk page. So I was kinda lost and was talking to my friend and psychologist and I realized if I never talk about my idea to anyone in a "comprehensive way" or show that it matters to me nothing is going to ever happen. So I started talking about my "idea" more. Nobody could understand the "idea" because I had not developed my skills regarding where to start...although the process had already started "automatically" and that's why I often think of "well my brain sort of activated me". I don't feel like I did have a plan and this idea happened. It happened "by itself". My brain reacted to what I was seeing in a video or stream. I value interaction highly in this idea. I think it would be helpful to make a community of people who are not paranoid about stuff that can express itself like "don't analyze me!", "don't compare me to anyone!". On the contrary, more often than not those adults who were diagnosed were actually openly comparing themselves with each other and I think that is healthy in a "science" way if done the "right way" which probably means "Do no harm". I found video material is important but I'm very unsure if uploading own video material to Wikimedia Commons would constitute a "reasonable" use of the resources there. Maybe somebody here needs to ask more questions to me that I should answer before that happens. I also know the '''be bold''' so I could just do what I think might be ok. Though I work better in a group as long as I know what "group configurations" help me. This is in a non-profit way. Since the state supported me this might be a way I am trying to "give back" to the state and "the world". May seem overly ambitious and crazy but this thing gives me energy. It gives me hope when trying to develop this idea.

Another was the lack of activity, which can be ameliorated by having it be part of an existing project instead of its own domain (e.g. some editions of Wikipedia host their own Wikinews already and those projects were not impacted by the closure). :* Are any changes to the scope of Wikinews proposed? ::*Not at this juncture. I would also propose as far as implemention goes that we would request a new namespace and that the material be more-or-less sequestered into its own ongoing project, like Wikijournal is or like the Cookbook and Wikijunior are at our sister [[:b:]]. :* How does [[Wikinews]] fit with the [[Wikiversity:Mission]]? What aligns well? Where might there be tension? :** e.g., I'm not sure that a page like [[Story/Manchester City moves two points behind Arsenal]] in and of itself will serve as an educational resource. ::*The process of citizen journalists practicing their craft in real-time and collaborating with others to do so is itself an education activity. We would essentially be hosting a real-time experiment in citizen journalism, online communities, and collaborative learning in addition to the prospect of spreading educational information from someone actually reading the news. I would propose that we could also make a more deliberate attempt to engage with learning <em>about</em> what does and doesn't work with collaborative news writing by experimentation (e.g. audio news, syndicating to other sites, incorporating freely-licensed news from other sources, writing hyper-local news, writing briefs versus longer-term reportage) and also seeing if the problems noted in the Task Force report that recommended closure can be overcome. Note that we have already done some local investigation about and learning about wiki-based journalism on Wikinews here at [[Journalism studies and Wikinews]]. We could continue that learning and refine the process, including incorporating journalism students from universities. As for tensions, Wikinews is the only sister project that must be done with a quick turn-around: if you take a long time to [[:s:|transcribe a book]], that's just how long it takes, but if you take a long time to write news, it ceases to be news entirely. Wikiversity has been a very slow-growing project that has definitely had some successes but has generally come together over a long period with most learning resources being individual passion projects (or sometimes, frankly, crankery) which would not work with collaborative news that requires more than just a single editor writing whatever he feels like. ::Please let me know any other questions/concerns and any other editors feel free to give your own perspective. ―[[User:Koavf|Justin (<span style="color:grey">ko'''a'''<span style="color:black">v</span>f</span>)]]<span style="color:red">❤[[User talk:Koavf|T]]☮[[Special:Contributions/Koavf|C]]☺[[Special:Emailuser/Koavf|M]]☯</span> 06:13, 14 May 2026 (UTC) :::Thanks, Justin — it is food for thought. :::In attempting to understand how we've arrived here, I've summarised some of the background on this page: [[Wikinews]]. :::Perhaps it could be helpful to flesh out more of the vision / ideas / possibilities / challenges on that page? -- [[User:Jtneill|Jtneill]] - <small>[[User talk:Jtneill|Talk]] - [[Special:Contributions/Jtneill|c]]</small> 11:49, 14 May 2026 (UTC) :::*Having given it some thought, in principle, I support hosting [[citizen journalism]] on Wikiversity where it is clearly connected to a learning project and/or constitutes original research, both of which align strongly with [[Wikiversity:Mission|Wikiversity’s educational mission]]. :::*My chief concern is the potential for news content that is not clearly linked to the purpose of Wikiversity. To avoid this, some community-agreed guidelines would be prudent. These need not be overly restrictive; they should support boldness and experimentation while helping ensure alignment with Wikiversity's purpose. :::*Given the reported low and declining activity on Wikinews, it seems unlikely that English Wikiversity would be overwhelmed by an influx of news-related editing. My impression is that English Wikinews was the most active edition, but even so, many contributors are likely to disperse to other projects or cease editing altogether. A modest migration of interested editors to Wikiversity seems manageable. :::*At this stage, I do not think a dedicated namespace is necessary. Subpages under [[Wikinews]] or nested pages under relevant learning or research projects, or user-space draft pages should be suitable. I agree that [[Wikijournal]] offers a useful model, as do several existing course structures on Wikiversity. :::*I support [[User:Koavf]]’s suggestions about framing Wikinews activity explicitly around learning. This would create a distinctive space for experimenting with collaborative news production in ways that are pedagogically meaningful. I agree that the [[journalism studies and Wikinews]] project developed by David and Leigh Blackall through the University of Wollongong is an excellent example of the intersection between Wikiversity and Wikinews. The [[Wikinews]] page could evolve into a hub for such projects. :::*I've tidied the [[:Category:Wikinews|Wikinews category]] and merged some content into the [[Wikinews]] page. As part of a reinvigoration effort, please review these and related resources such as [[:Category:Journalism]] and [[School:Journalism]]. :::*A further argument in favour of this initiative is that Wikipedia explicitly excludes both news reporting and original research. So, there is value in maintaining spaces within the Wikimedia ecosystem where these forms of knowledge production can be openly developed and curated. Such work can, in turn, generate valuable evidence and source material that may later inform Wikipedia articles. :::*The closure of WMF-hosted Wikinews does not imply that open wiki-based news curation lacks value. Indeed, the closure documentation appears supportive of experimentation with alternative news models across Wikimedia projects, including through Wikipedia and Wikidata. In that context, Wikiversity seems a natural home for a Wikinews experiment, provided it is clearly grounded in learning and/or research. :::-- [[User:Jtneill|Jtneill]] - <small>[[User talk:Jtneill|Talk]] - [[Special:Contributions/Jtneill|c]]</small> 11:39, 15 May 2026 (UTC) My understanding towards Wikinews' failure is that everything takes too long to be approved for the publish status, which means that any breaking news would have already become days-old stale news. Wikinews has a brand recognition (for right or wrong reasons) than Wikiversity and I wonder how effective Wikiversity can attract the "Wikinews refugees" to edit here. And just a quick note on the governance. Since each Wikiversity language operates independently, each language has to vote & adopt this proposal independently.

[[User:Juandev|Juandev]] ([[User talk:Juandev|discuss]] • [[Special:Contributions/Juandev|contribs]]) 19:14, 1 April 2026 (UTC) :Wikiversity's biggest issue in recent times was the hosting of low-quality, trash content. Thankfully we've done a great job in removing pseudoscience and other embarrassingly trash content (Wikidebates, for example), but the biggest concern moving forward is proper maintenance IMO. I've caught several pseudoscience pages being created within the last few months that could easily have flown under the radar (ex, [[The Kelemen Dilemma: Causal Collapse and Axiomatic Instability]]), so I'd urge our custodians/curators to be on the lookout for this type of content. Usually an AI-overview can point this type of content out relatively well. :In terms of visibility, I believe Wikiversity is a high-traffic project. I remember my [[Mathematical Properties]] showing up on the first page of Google when searching up "math properties" for the longest time (and is still showing up in the first page 'till this day!). Besides, Wikinews hosted a lot of short-term content (the nature of news articles), while Wikiversity hosts content that can still be useful a decade later (ex, [[A Reader's Guide to Annotation]]). :I think we are on a better path than we were a few months ago, and I do want to thank everyone here who has been helping out with maintaining our website! —[[User:Atcovi|Atcovi]] [[User talk:Atcovi|(Talk]] - [[Special:Contributions/Atcovi|Contribs)]] 20:48, 1 April 2026 (UTC) :For what it's worth, the group that did that study has since disbanded, so no one is monitoring the other sister projects in the same way. Additionally, Wikinews had some catastrophic server issues due to the maintenance of [[:m:Extension:DynamicPageList]] which don't apply here. Your questions are still worth addressing, but I just wanted to cut off any concern at the pass about Wikiversity being in the same precarious situation. Wikiversity is definitely the biggest "lagging behind" or "failure" project now that Wikinews is being shuttered, but I don't see any near- or medium-term pathway to closing Wikiversity. —[[User:Koavf|Justin (<span style="color:grey">ko'''a'''vf</span>)]]<span style="color:red">❤[[User talk:Koavf|T]]☮[[Special:Contributions/Koavf|C]]☺[[Special:Emailuser/Koavf|M]]☯</span> 00:46, 2 April 2026 (UTC) :[[w:en:Wikipedia:Wikipedia Signpost/2026-03-31/News and notes|Entirety of Wikinews to be shut down]] (Wikipedia Signpost) -- [[User:Jtneill|Jtneill]] - <small>[[User talk:Jtneill|Talk]] - [[Special:Contributions/Jtneill|c]]</small> 02:03, 11 April 2026 (UTC) == Action Required: Update templates/modules for electoral maps (Migrating from P1846 to P14226) == Hello everyone, This is a notice regarding an ongoing data migration on Wikidata that may affect your election-related templates and Lua modules (such as <code>Module:Itemgroup/list</code>). '''The Change:'''<br /> Currently, many templates pull electoral maps from Wikidata using the property [[:d:Property:P1846|P1846]], combined with the qualifier [[:d:Property:P180|P180]]: [[:d:Q19571328|Q19571328]].

'''What You Need To Do:'''<br /> To ensure your templates and infoboxes do not break or lose their maps, please update your local code to fetch data from [[:d:Property:P14226|P14226]] instead of the old [[:d:Property:P1846|P1846]] + [[:d:Property:P180|P180]] structure. A [[m:Wikidata/Property Migration: P1846 to P14226/List|list of pages]] was generated using Wikimedia Global Search. '''Deadline:'''<br /> We are temporarily retaining the old data on [[:d:Property:P1846|P1846]] to allow for a smooth transition. However, to complete the data cleanup on Wikidata, the old [[:d:Property:P1846|P1846]] statements will be removed after '''May 1, 2026'''. Please update your modules and templates before this date to prevent any disruption to your wiki's election articles. Let us know if you have any questions or need assistance with the query logic.

What I've called it so far is "The Neurodiversity-inspired Idea". At other times I used more sensationalist wording but here on Wikiversity I don't dare do that. I actually woke up with thinking about putting this into my userspace draft: "Personal Observations Made By Meeting Autistic and Non-Autistic Adults". My ultimate goal is to stop blathering about my "idea" to friend and family without feeling my "methodology" is going into any progressive direction whatsoever. My latest encounter was somewhat constructive though. A friend of a friend who worked with people presenting ideas in attempting to getting grants. I don't want a grant. I just want to figure out how I can express my "idea" in a way so that I can more clearly figure out what flaws it got. At the same time I tend to overthink. If anyone thinks etherpad might be a good place and considering Wikimedia already got an etherpad at https://etherpad.wikimedia.org/ if anyone feels like they know me better in the future feel free to suggest a "session" on etherpad. '''If I don't receive a reply to this in 1 week's time I will begin to explore this "idea" into my userspace''' unless you replied and refrained me from doing so, of course. Then maybe after "developing it there" I might reference it to you another future time here in the Colloquium, with my "idea" still in my userspace draft. This "idea" is sort of a burden, I'm happy I've made the choice to get rid of it and hopefully move on with my life, unless there is something to this "idea". My failure is probably evident: I feel I haven't told you anything. Same happened to when I talked to friends and family. In danger of overthinking it further I'll publish this right now.

Is there anyone here who is interested for Neurodiversity to be "something more" than it already is? Does anyone here consider Neurodiversity one of the "harder topics" to work on or discuss? Does anyone here have an opinion about the [[Neurodiversity Movement]]? So these questions don't appear like "out of a vacuum" I can tell you a bit about my background: Many years ago I got a psychiatric diagnosis "Asperger's". After I stepped out of the office and my Äsperger's was 'concluded', I stepped out into the street and thought my first negative thought(but the positive thought followed after). The thought was about concentration camps in the second world war and that the world seemed to be going into the direction of "labeling others". I was unsure whether this was "real science" and sort of "challenged myself" to make up my own mind after meeting people that had been given this diagnosis. The more adults with this diagnosis I met the more I started seeing "patterns". Was it a coincidence that the first person with Asperger's I met reminded me about my father later after I had plenty of times of experience with interacting with him? None of the people I interacted with online through IRC text chat...I felt I got any clue about how "their brains work". Only when I met one person from the Asperger's chat community in person we both realized that whatever we experienced was akin to the "chaos theory". He told me about "chaos theory" while I didn't know even what that term meant but I guess I 'read between the lines'. My question that I linger on still today is "did he understand about me what I think I understood about him?"? That our brains had the same configuration? Most autistic adults who meet other autistic adults usually get disappointed. They think the diagnosis will help them meet somebody like themselves and then they realize the great diversity in the autistic spectrum created by Psychiatry. I later stopped interacting with autistic communities that much, I felt that it did not benefit me. Also Neurodiversity's "neurotypes" interested me for a while until I realized I had "misunderstood everything" about them and how they are used in the Neurodiversity Movement or "Neurodiversity community" if that even can precisely be defined? I doubt it but if you want to contribute to the [[Neurodiversity Movement]]. My previous attempts failed as I got more and more confused. I think a community project needs a community. With a lack of that I don't think it is worth my time. If any of you would like to work on that project let me know on my talk page. So I was kinda lost and was talking to my friend and psychologist and I realized if I never talk about my idea to anyone in a "comprehensive way" or show that it matters to me nothing is going to ever happen. So I started talking about my "idea" more. Nobody could understand the "idea" because I had not developed my skills regarding where to start...although the process had already started "automatically" and that's why I often think of "well my brain sort of activated me". I don't feel like I did have a plan and this idea happened. It happened "by itself". My brain reacted to what I was seeing in a video or stream. I value interaction highly in this idea. I think it would be helpful to make a community of people who are not paranoid about stuff that can express itself like "don't analyze me!", "don't compare me to anyone!". On the contrary, more often than not those adults who were diagnosed were actually openly comparing themselves with each other and I think that is healthy in a "science" way if done the "right way" which probably means "Do no harm". I found video material is important but I'm very unsure if uploading own video material to Wikimedia Commons would constitute a "reasonable" use of the resources there. Maybe somebody here needs to ask more questions to me that I should answer before that happens. I also know the '''be bold''' so I could just do what I think might be ok. Though I work better in a group as long as I know what "group configurations" help me. This is in a non-profit way. Since the state supported me this might be a way I am trying to "give back" to the state and "the world". May seem overly ambitious and crazy but this thing gives me energy. It gives me hope when trying to develop this idea.

Another was the lack of activity, which can be ameliorated by having it be part of an existing project instead of its own domain (e.g. some editions of Wikipedia host their own Wikinews already and those projects were not impacted by the closure). :* Are any changes to the scope of Wikinews proposed? ::*Not at this juncture. I would also propose as far as implemention goes that we would request a new namespace and that the material be more-or-less sequestered into its own ongoing project, like Wikijournal is or like the Cookbook and Wikijunior are at our sister [[:b:]]. :* How does [[Wikinews]] fit with the [[Wikiversity:Mission]]? What aligns well? Where might there be tension? :** e.g., I'm not sure that a page like [[Story/Manchester City moves two points behind Arsenal]] in and of itself will serve as an educational resource. ::*The process of citizen journalists practicing their craft in real-time and collaborating with others to do so is itself an education activity. We would essentially be hosting a real-time experiment in citizen journalism, online communities, and collaborative learning in addition to the prospect of spreading educational information from someone actually reading the news. I would propose that we could also make a more deliberate attempt to engage with learning <em>about</em> what does and doesn't work with collaborative news writing by experimentation (e.g. audio news, syndicating to other sites, incorporating freely-licensed news from other sources, writing hyper-local news, writing briefs versus longer-term reportage) and also seeing if the problems noted in the Task Force report that recommended closure can be overcome. Note that we have already done some local investigation about and learning about wiki-based journalism on Wikinews here at [[Journalism studies and Wikinews]]. We could continue that learning and refine the process, including incorporating journalism students from universities. As for tensions, Wikinews is the only sister project that must be done with a quick turn-around: if you take a long time to [[:s:|transcribe a book]], that's just how long it takes, but if you take a long time to write news, it ceases to be news entirely. Wikiversity has been a very slow-growing project that has definitely had some successes but has generally come together over a long period with most learning resources being individual passion projects (or sometimes, frankly, crankery) which would not work with collaborative news that requires more than just a single editor writing whatever he feels like. ::Please let me know any other questions/concerns and any other editors feel free to give your own perspective. ―[[User:Koavf|Justin (<span style="color:grey">ko'''a'''<span style="color:black">v</span>f</span>)]]<span style="color:red">❤[[User talk:Koavf|T]]☮[[Special:Contributions/Koavf|C]]☺[[Special:Emailuser/Koavf|M]]☯</span> 06:13, 14 May 2026 (UTC) :::Thanks, Justin — it is food for thought. :::In attempting to understand how we've arrived here, I've summarised some of the background on this page: [[Wikinews]]. :::Perhaps it could be helpful to flesh out more of the vision / ideas / possibilities / challenges on that page? -- [[User:Jtneill|Jtneill]] - <small>[[User talk:Jtneill|Talk]] - [[Special:Contributions/Jtneill|c]]</small> 11:49, 14 May 2026 (UTC) :::*Having given it some thought, in principle, I support hosting [[citizen journalism]] on Wikiversity where it is clearly connected to a learning project and/or constitutes original research, both of which align strongly with [[Wikiversity:Mission|Wikiversity’s educational mission]]. :::*My chief concern is the potential for news content that is not clearly linked to the purpose of Wikiversity. To avoid this, some community-agreed guidelines would be prudent. These need not be overly restrictive; they should support boldness and experimentation while helping ensure alignment with Wikiversity's purpose. :::*Given the reported low and declining activity on Wikinews, it seems unlikely that English Wikiversity would be overwhelmed by an influx of news-related editing. My impression is that English Wikinews was the most active edition, but even so, many contributors are likely to disperse to other projects or cease editing altogether. A modest migration of interested editors to Wikiversity seems manageable. :::*At this stage, I do not think a dedicated namespace is necessary. Subpages under [[Wikinews]] or nested pages under relevant learning or research projects, or user-space draft pages should be suitable. I agree that [[Wikijournal]] offers a useful model, as do several existing course structures on Wikiversity. :::*I support [[User:Koavf]]’s suggestions about framing Wikinews activity explicitly around learning. This would create a distinctive space for experimenting with collaborative news production in ways that are pedagogically meaningful. I agree that the [[journalism studies and Wikinews]] project developed by David and Leigh Blackall through the University of Wollongong is an excellent example of the intersection between Wikiversity and Wikinews. The [[Wikinews]] page could evolve into a hub for such projects. :::*I've tidied the [[:Category:Wikinews|Wikinews category]] and merged some content into the [[Wikinews]] page. As part of a reinvigoration effort, please review these and related resources such as [[:Category:Journalism]] and [[School:Journalism]]. :::*A further argument in favour of this initiative is that Wikipedia explicitly excludes both news reporting and original research. So, there is value in maintaining spaces within the Wikimedia ecosystem where these forms of knowledge production can be openly developed and curated. Such work can, in turn, generate valuable evidence and source material that may later inform Wikipedia articles. :::*The closure of WMF-hosted Wikinews does not imply that open wiki-based news curation lacks value. Indeed, the closure documentation appears supportive of experimentation with alternative news models across Wikimedia projects, including through Wikipedia and Wikidata. In that context, Wikiversity seems a natural home for a Wikinews experiment, provided it is clearly grounded in learning and/or research. :::-- [[User:Jtneill|Jtneill]] - <small>[[User talk:Jtneill|Talk]] - [[Special:Contributions/Jtneill|c]]</small> 11:39, 15 May 2026 (UTC) My understanding towards Wikinews' failure is that everything takes too long to be approved for the publish status, which means that any breaking news would have already become days-old stale news. Wikinews has a brand recognition (for right or wrong reasons) than Wikiversity and I wonder how effective Wikiversity can attract the "Wikinews refugees" to edit here. And just a quick note on the governance. Since each Wikiversity language operates independently, each language has to vote & adopt this proposal independently.

[[User:Juandev|Juandev]] ([[User talk:Juandev|discuss]] • [[Special:Contributions/Juandev|contribs]]) 19:14, 1 April 2026 (UTC) :Wikiversity's biggest issue in recent times was the hosting of low-quality, trash content. Thankfully we've done a great job in removing pseudoscience and other embarrassingly trash content (Wikidebates, for example), but the biggest concern moving forward is proper maintenance IMO. I've caught several pseudoscience pages being created within the last few months that could easily have flown under the radar (ex, [[The Kelemen Dilemma: Causal Collapse and Axiomatic Instability]]), so I'd urge our custodians/curators to be on the lookout for this type of content. Usually an AI-overview can point this type of content out relatively well. :In terms of visibility, I believe Wikiversity is a high-traffic project. I remember my [[Mathematical Properties]] showing up on the first page of Google when searching up "math properties" for the longest time (and is still showing up in the first page 'till this day!). Besides, Wikinews hosted a lot of short-term content (the nature of news articles), while Wikiversity hosts content that can still be useful a decade later (ex, [[A Reader's Guide to Annotation]]). :I think we are on a better path than we were a few months ago, and I do want to thank everyone here who has been helping out with maintaining our website! —[[User:Atcovi|Atcovi]] [[User talk:Atcovi|(Talk]] - [[Special:Contributions/Atcovi|Contribs)]] 20:48, 1 April 2026 (UTC) :For what it's worth, the group that did that study has since disbanded, so no one is monitoring the other sister projects in the same way.

Your questions are still worth addressing, but I just wanted to cut off any concern at the pass about Wikiversity being in the same precarious situation. Wikiversity is definitely the biggest "lagging behind" or "failure" project now that Wikinews is being shuttered, but I don't see any near- or medium-term pathway to closing Wikiversity. —[[User:Koavf|Justin (<span style="color:grey">ko'''a'''vf</span>)]]<span style="color:red">❤[[User talk:Koavf|T]]☮[[Special:Contributions/Koavf|C]]☺[[Special:Emailuser/Koavf|M]]☯</span> 00:46, 2 April 2026 (UTC) :[[w:en:Wikipedia:Wikipedia Signpost/2026-03-31/News and notes|Entirety of Wikinews to be shut down]] (Wikipedia Signpost) -- [[User:Jtneill|Jtneill]] - <small>[[User talk:Jtneill|Talk]] - [[Special:Contributions/Jtneill|c]]</small> 02:03, 11 April 2026 (UTC) == Action Required: Update templates/modules for electoral maps (Migrating from P1846 to P14226) == Hello everyone, This is a notice regarding an ongoing data migration on Wikidata that may affect your election-related templates and Lua modules (such as <code>Module:Itemgroup/list</code>). '''The Change:'''<br /> Currently, many templates pull electoral maps from Wikidata using the property [[:d:Property:P1846|P1846]], combined with the qualifier [[:d:Property:P180|P180]]: [[:d:Q19571328|Q19571328]].

'''What You Need To Do:'''<br /> To ensure your templates and infoboxes do not break or lose their maps, please update your local code to fetch data from [[:d:Property:P14226|P14226]] instead of the old [[:d:Property:P1846|P1846]] + [[:d:Property:P180|P180]] structure.

'''Deadline:'''<br /> We are temporarily retaining the old data on [[:d:Property:P1846|P1846]] to allow for a smooth transition. However, to complete the data cleanup on Wikidata, the old [[:d:Property:P1846|P1846]] statements will be removed after '''May 1, 2026'''. Please update your modules and templates before this date to prevent any disruption to your wiki's election articles. Let us know if you have any questions or need assistance with the query logic.

What I've called it so far is "The Neurodiversity-inspired Idea". At other times I used more sensationalist wording but here on Wikiversity I don't dare do that. I actually woke up with thinking about putting this into my userspace draft: "Personal Observations Made By Meeting Autistic and Non-Autistic Adults". My ultimate goal is to stop blathering about my "idea" to friend and family without feeling my "methodology" is going into any progressive direction whatsoever. My latest encounter was somewhat constructive though. A friend of a friend who worked with people presenting ideas in attempting to getting grants. I don't want a grant. I just want to figure out how I can express my "idea" in a way so that I can more clearly figure out what flaws it got. At the same time I tend to overthink. If anyone thinks etherpad might be a good place and considering Wikimedia already got an etherpad at https://etherpad.wikimedia.org/ if anyone feels like they know me better in the future feel free to suggest a "session" on etherpad. '''If I don't receive a reply to this in 1 week's time I will begin to explore this "idea" into my userspace''' unless you replied and refrained me from doing so, of course. Then maybe after "developing it there" I might reference it to you another future time here in the Colloquium, with my "idea" still in my userspace draft. This "idea" is sort of a burden, I'm happy I've made the choice to get rid of it and hopefully move on with my life, unless there is something to this "idea". My failure is probably evident: I feel I haven't told you anything. Same happened to when I talked to friends and family. In danger of overthinking it further I'll publish this right now.

Is there anyone here who is interested for Neurodiversity to be "something more" than it already is? Does anyone here consider Neurodiversity one of the "harder topics" to work on or discuss? Does anyone here have an opinion about the [[Neurodiversity Movement]]? So these questions don't appear like "out of a vacuum" I can tell you a bit about my background: Many years ago I got a psychiatric diagnosis "Asperger's". After I stepped out of the office and my Äsperger's was 'concluded', I stepped out into the street and thought my first negative thought(but the positive thought followed after). The thought was about concentration camps in the second world war and that the world seemed to be going into the direction of "labeling others". I was unsure whether this was "real science" and sort of "challenged myself" to make up my own mind after meeting people that had been given this diagnosis. The more adults with this diagnosis I met the more I started seeing "patterns". Was it a coincidence that the first person with Asperger's I met reminded me about my father later after I had plenty of times of experience with interacting with him? None of the people I interacted with online through IRC text chat...I felt I got any clue about how "their brains work". Only when I met one person from the Asperger's chat community in person we both realized that whatever we experienced was akin to the "chaos theory". He told me about "chaos theory" while I didn't know even what that term meant but I guess I 'read between the lines'. My question that I linger on still today is "did he understand about me what I think I understood about him?"? That our brains had the same configuration? Most autistic adults who meet other autistic adults usually get disappointed. They think the diagnosis will help them meet somebody like themselves and then they realize the great diversity in the autistic spectrum created by Psychiatry. I later stopped interacting with autistic communities that much, I felt that it did not benefit me. Also Neurodiversity's "neurotypes" interested me for a while until I realized I had "misunderstood everything" about them and how they are used in the Neurodiversity Movement or "Neurodiversity community" if that even can precisely be defined? I doubt it but if you want to contribute to the [[Neurodiversity Movement]]. My previous attempts failed as I got more and more confused. I think a community project needs a community. With a lack of that I don't think it is worth my time. If any of you would like to work on that project let me know on my talk page. So I was kinda lost and was talking to my friend and psychologist and I realized if I never talk about my idea to anyone in a "comprehensive way" or show that it matters to me nothing is going to ever happen. So I started talking about my "idea" more. Nobody could understand the "idea" because I had not developed my skills regarding where to start...although the process had already started "automatically" and that's why I often think of "well my brain sort of activated me". I don't feel like I did have a plan and this idea happened. It happened "by itself". My brain reacted to what I was seeing in a video or stream. I value interaction highly in this idea. I think it would be helpful to make a community of people who are not paranoid about stuff that can express itself like "don't analyze me!", "don't compare me to anyone!". On the contrary, more often than not those adults who were diagnosed were actually openly comparing themselves with each other and I think that is healthy in a "science" way if done the "right way" which probably means "Do no harm". I found video material is important but I'm very unsure if uploading own video material to Wikimedia Commons would constitute a "reasonable" use of the resources there. Maybe somebody here needs to ask more questions to me that I should answer before that happens. I also know the '''be bold''' so I could just do what I think might be ok. Though I work better in a group as long as I know what "group configurations" help me. This is in a non-profit way. Since the state supported me this might be a way I am trying to "give back" to the state and "the world". May seem overly ambitious and crazy but this thing gives me energy. It gives me hope when trying to develop this idea.

Another was the lack of activity, which can be ameliorated by having it be part of an existing project instead of its own domain (e.g. some editions of Wikipedia host their own Wikinews already and those projects were not impacted by the closure). :* Are any changes to the scope of Wikinews proposed? ::*Not at this juncture. I would also propose as far as implemention goes that we would request a new namespace and that the material be more-or-less sequestered into its own ongoing project, like Wikijournal is or like the Cookbook and Wikijunior are at our sister [[:b:]]. :* How does [[Wikinews]] fit with the [[Wikiversity:Mission]]? What aligns well? Where might there be tension? :** e.g., I'm not sure that a page like [[Story/Manchester City moves two points behind Arsenal]] in and of itself will serve as an educational resource. ::*The process of citizen journalists practicing their craft in real-time and collaborating with others to do so is itself an education activity. We would essentially be hosting a real-time experiment in citizen journalism, online communities, and collaborative learning in addition to the prospect of spreading educational information from someone actually reading the news. I would propose that we could also make a more deliberate attempt to engage with learning <em>about</em> what does and doesn't work with collaborative news writing by experimentation (e.g. audio news, syndicating to other sites, incorporating freely-licensed news from other sources, writing hyper-local news, writing briefs versus longer-term reportage) and also seeing if the problems noted in the Task Force report that recommended closure can be overcome. Note that we have already done some local investigation about and learning about wiki-based journalism on Wikinews here at [[Journalism studies and Wikinews]]. We could continue that learning and refine the process, including incorporating journalism students from universities. As for tensions, Wikinews is the only sister project that must be done with a quick turn-around: if you take a long time to [[:s:|transcribe a book]], that's just how long it takes, but if you take a long time to write news, it ceases to be news entirely. Wikiversity has been a very slow-growing project that has definitely had some successes but has generally come together over a long period with most learning resources being individual passion projects (or sometimes, frankly, crankery) which would not work with collaborative news that requires more than just a single editor writing whatever he feels like. ::Please let me know any other questions/concerns and any other editors feel free to give your own perspective. ―[[User:Koavf|Justin (<span style="color:grey">ko'''a'''<span style="color:black">v</span>f</span>)]]<span style="color:red">❤[[User talk:Koavf|T]]☮[[Special:Contributions/Koavf|C]]☺[[Special:Emailuser/Koavf|M]]☯</span> 06:13, 14 May 2026 (UTC) :::Thanks, Justin — it is food for thought. :::In attempting to understand how we've arrived here, I've summarised some of the background on this page: [[Wikinews]]. :::Perhaps it could be helpful to flesh out more of the vision / ideas / possibilities / challenges on that page? -- [[User:Jtneill|Jtneill]] - <small>[[User talk:Jtneill|Talk]] - [[Special:Contributions/Jtneill|c]]</small> 11:49, 14 May 2026 (UTC) :::*Having given it some thought, in principle, I support hosting [[citizen journalism]] on Wikiversity where it is clearly connected to a learning project and/or constitutes original research, both of which align strongly with [[Wikiversity:Mission|Wikiversity’s educational mission]]. :::*My chief concern is the potential for news content that is not clearly linked to the purpose of Wikiversity. To avoid this, some community-agreed guidelines would be prudent. These need not be overly restrictive; they should support boldness and experimentation while helping ensure alignment with Wikiversity's purpose. :::*Given the reported low and declining activity on Wikinews, it seems unlikely that English Wikiversity would be overwhelmed by an influx of news-related editing. My impression is that English Wikinews was the most active edition, but even so, many contributors are likely to disperse to other projects or cease editing altogether. A modest migration of interested editors to Wikiversity seems manageable. :::*At this stage, I do not think a dedicated namespace is necessary. Subpages under [[Wikinews]] or nested pages under relevant learning or research projects, or user-space draft pages should be suitable. I agree that [[Wikijournal]] offers a useful model, as do several existing course structures on Wikiversity. :::*I support [[User:Koavf]]’s suggestions about framing Wikinews activity explicitly around learning. This would create a distinctive space for experimenting with collaborative news production in ways that are pedagogically meaningful. I agree that the [[journalism studies and Wikinews]] project developed by David and Leigh Blackall through the University of Wollongong is an excellent example of the intersection between Wikiversity and Wikinews. The [[Wikinews]] page could evolve into a hub for such projects. :::*I've tidied the [[:Category:Wikinews|Wikinews category]] and merged some content into the [[Wikinews]] page. As part of a reinvigoration effort, please review these and related resources such as [[:Category:Journalism]] and [[School:Journalism]]. :::*A further argument in favour of this initiative is that Wikipedia explicitly excludes both news reporting and original research. So, there is value in maintaining spaces within the Wikimedia ecosystem where these forms of knowledge production can be openly developed and curated. Such work can, in turn, generate valuable evidence and source material that may later inform Wikipedia articles. :::*The closure of WMF-hosted Wikinews does not imply that open wiki-based news curation lacks value. Indeed, the closure documentation appears supportive of experimentation with alternative news models across Wikimedia projects, including through Wikipedia and Wikidata. In that context, Wikiversity seems a natural home for a Wikinews experiment, provided it is clearly grounded in learning and/or research. :::-- [[User:Jtneill|Jtneill]] - <small>[[User talk:Jtneill|Talk]] - [[Special:Contributions/Jtneill|c]]</small> 11:39, 15 May 2026 (UTC) My understanding towards Wikinews' failure is that everything takes too long to be approved for the publish status, which means that any breaking news would have already become days-old stale news. Wikinews has a brand recognition (for right or wrong reasons) than Wikiversity and I wonder how effective Wikiversity can attract the "Wikinews refugees" to edit here. And just a quick note on the governance. Since each Wikiversity language operates independently, each language has to vote & adopt this proposal independently.

[[User:Juandev|Juandev]] ([[User talk:Juandev|discuss]] • [[Special:Contributions/Juandev|contribs]]) 19:14, 1 April 2026 (UTC) :Wikiversity's biggest issue in recent times was the hosting of low-quality, trash content. Thankfully we've done a great job in removing pseudoscience and other embarrassingly trash content (Wikidebates, for example), but the biggest concern moving forward is proper maintenance IMO. I've caught several pseudoscience pages being created within the last few months that could easily have flown under the radar (ex, [[The Kelemen Dilemma: Causal Collapse and Axiomatic Instability]]), so I'd urge our custodians/curators to be on the lookout for this type of content. Usually an AI-overview can point this type of content out relatively well. :In terms of visibility, I believe Wikiversity is a high-traffic project. I remember my [[Mathematical Properties]] showing up on the first page of Google when searching up "math properties" for the longest time (and is still showing up in the first page 'till this day!). Besides, Wikinews hosted a lot of short-term content (the nature of news articles), while Wikiversity hosts content that can still be useful a decade later (ex, [[A Reader's Guide to Annotation]]). :I think we are on a better path than we were a few months ago, and I do want to thank everyone here who has been helping out with maintaining our website! —[[User:Atcovi|Atcovi]] [[User talk:Atcovi|(Talk]] - [[Special:Contributions/Atcovi|Contribs)]] 20:48, 1 April 2026 (UTC) :For what it's worth, the group that did that study has since disbanded, so no one is monitoring the other sister projects in the same way.

Your questions are still worth addressing, but I just wanted to cut off any concern at the pass about Wikiversity being in the same precarious situation. Wikiversity is definitely the biggest "lagging behind" or "failure" project now that Wikinews is being shuttered, but I don't see any near- or medium-term pathway to closing Wikiversity. —[[User:Koavf|Justin (<span style="color:grey">ko'''a'''vf</span>)]]<span style="color:red">❤[[User talk:Koavf|T]]☮[[Special:Contributions/Koavf|C]]☺[[Special:Emailuser/Koavf|M]]☯</span> 00:46, 2 April 2026 (UTC) :[[w:en:Wikipedia:Wikipedia Signpost/2026-03-31/News and notes|Entirety of Wikinews to be shut down]] (Wikipedia Signpost) -- [[User:Jtneill|Jtneill]] - <small>[[User talk:Jtneill|Talk]] - [[Special:Contributions/Jtneill|c]]</small> 02:03, 11 April 2026 (UTC) == Action Required: Update templates/modules for electoral maps (Migrating from P1846 to P14226) == Hello everyone, This is a notice regarding an ongoing data migration on Wikidata that may affect your election-related templates and Lua modules (such as <code>Module:Itemgroup/list</code>). '''The Change:'''<br /> Currently, many templates pull electoral maps from Wikidata using the property [[:d:Property:P1846|P1846]], combined with the qualifier [[:d:Property:P180|P180]]: [[:d:Q19571328|Q19571328]].

'''What You Need To Do:'''<br /> To ensure your templates and infoboxes do not break or lose their maps, please update your local code to fetch data from [[:d:Property:P14226|P14226]] instead of the old [[:d:Property:P1846|P1846]] + [[:d:Property:P180|P180]] structure.

'''Deadline:'''<br /> We are temporarily retaining the old data on [[:d:Property:P1846|P1846]] to allow for a smooth transition. However, to complete the data cleanup on Wikidata, the old [[:d:Property:P1846|P1846]] statements will be removed after '''May 1, 2026'''.

What I've called it so far is "The Neurodiversity-inspired Idea". At other times I used more sensationalist wording but here on Wikiversity I don't dare do that. I actually woke up with thinking about putting this into my userspace draft: "Personal Observations Made By Meeting Autistic and Non-Autistic Adults". My ultimate goal is to stop blathering about my "idea" to friend and family without feeling my "methodology" is going into any progressive direction whatsoever. My latest encounter was somewhat constructive though. A friend of a friend who worked with people presenting ideas in attempting to getting grants. I don't want a grant. I just want to figure out how I can express my "idea" in a way so that I can more clearly figure out what flaws it got. At the same time I tend to overthink.

'''If I don't receive a reply to this in 1 week's time I will begin to explore this "idea" into my userspace''' unless you replied and refrained me from doing so, of course. Then maybe after "developing it there" I might reference it to you another future time here in the Colloquium, with my "idea" still in my userspace draft. This "idea" is sort of a burden, I'm happy I've made the choice to get rid of it and hopefully move on with my life, unless there is something to this "idea". My failure is probably evident: I feel I haven't told you anything. Same happened to when I talked to friends and family. In danger of overthinking it further I'll publish this right now.

Is there anyone here who is interested for Neurodiversity to be "something more" than it already is? Does anyone here consider Neurodiversity one of the "harder topics" to work on or discuss? Does anyone here have an opinion about the [[Neurodiversity Movement]]? So these questions don't appear like "out of a vacuum" I can tell you a bit about my background: Many years ago I got a psychiatric diagnosis "Asperger's". After I stepped out of the office and my Äsperger's was 'concluded', I stepped out into the street and thought my first negative thought(but the positive thought followed after). The thought was about concentration camps in the second world war and that the world seemed to be going into the direction of "labeling others". I was unsure whether this was "real science" and sort of "challenged myself" to make up my own mind after meeting people that had been given this diagnosis. The more adults with this diagnosis I met the more I started seeing "patterns". Was it a coincidence that the first person with Asperger's I met reminded me about my father later after I had plenty of times of experience with interacting with him? None of the people I interacted with online through IRC text chat...I felt I got any clue about how "their brains work". Only when I met one person from the Asperger's chat community in person we both realized that whatever we experienced was akin to the "chaos theory". He told me about "chaos theory" while I didn't know even what that term meant but I guess I 'read between the lines'. My question that I linger on still today is "did he understand about me what I think I understood about him?"? That our brains had the same configuration? Most autistic adults who meet other autistic adults usually get disappointed. They think the diagnosis will help them meet somebody like themselves and then they realize the great diversity in the autistic spectrum created by Psychiatry. I later stopped interacting with autistic communities that much, I felt that it did not benefit me. Also Neurodiversity's "neurotypes" interested me for a while until I realized I had "misunderstood everything" about them and how they are used in the Neurodiversity Movement or "Neurodiversity community" if that even can precisely be defined? I doubt it but if you want to contribute to the [[Neurodiversity Movement]]. My previous attempts failed as I got more and more confused. I think a community project needs a community. With a lack of that I don't think it is worth my time. If any of you would like to work on that project let me know on my talk page. So I was kinda lost and was talking to my friend and psychologist and I realized if I never talk about my idea to anyone in a "comprehensive way" or show that it matters to me nothing is going to ever happen. So I started talking about my "idea" more. Nobody could understand the "idea" because I had not developed my skills regarding where to start...although the process had already started "automatically" and that's why I often think of "well my brain sort of activated me". I don't feel like I did have a plan and this idea happened. It happened "by itself". My brain reacted to what I was seeing in a video or stream. I value interaction highly in this idea. I think it would be helpful to make a community of people who are not paranoid about stuff that can express itself like "don't analyze me!", "don't compare me to anyone!". On the contrary, more often than not those adults who were diagnosed were actually openly comparing themselves with each other and I think that is healthy in a "science" way if done the "right way" which probably means "Do no harm". I found video material is important but I'm very unsure if uploading own video material to Wikimedia Commons would constitute a "reasonable" use of the resources there. Maybe somebody here needs to ask more questions to me that I should answer before that happens. I also know the '''be bold''' so I could just do what I think might be ok. Though I work better in a group as long as I know what "group configurations" help me. This is in a non-profit way. Since the state supported me this might be a way I am trying to "give back" to the state and "the world". May seem overly ambitious and crazy but this thing gives me energy. It gives me hope when trying to develop this idea.

Another was the lack of activity, which can be ameliorated by having it be part of an existing project instead of its own domain (e.g. some editions of Wikipedia host their own Wikinews already and those projects were not impacted by the closure). :* Are any changes to the scope of Wikinews proposed? ::*Not at this juncture. I would also propose as far as implemention goes that we would request a new namespace and that the material be more-or-less sequestered into its own ongoing project, like Wikijournal is or like the Cookbook and Wikijunior are at our sister [[:b:]]. :* How does [[Wikinews]] fit with the [[Wikiversity:Mission]]? What aligns well? Where might there be tension? :** e.g., I'm not sure that a page like [[Story/Manchester City moves two points behind Arsenal]] in and of itself will serve as an educational resource. ::*The process of citizen journalists practicing their craft in real-time and collaborating with others to do so is itself an education activity. We would essentially be hosting a real-time experiment in citizen journalism, online communities, and collaborative learning in addition to the prospect of spreading educational information from someone actually reading the news. I would propose that we could also make a more deliberate attempt to engage with learning <em>about</em> what does and doesn't work with collaborative news writing by experimentation (e.g. audio news, syndicating to other sites, incorporating freely-licensed news from other sources, writing hyper-local news, writing briefs versus longer-term reportage) and also seeing if the problems noted in the Task Force report that recommended closure can be overcome. Note that we have already done some local investigation about and learning about wiki-based journalism on Wikinews here at [[Journalism studies and Wikinews]]. We could continue that learning and refine the process, including incorporating journalism students from universities. As for tensions, Wikinews is the only sister project that must be done with a quick turn-around: if you take a long time to [[:s:|transcribe a book]], that's just how long it takes, but if you take a long time to write news, it ceases to be news entirely. Wikiversity has been a very slow-growing project that has definitely had some successes but has generally come together over a long period with most learning resources being individual passion projects (or sometimes, frankly, crankery) which would not work with collaborative news that requires more than just a single editor writing whatever he feels like. ::Please let me know any other questions/concerns and any other editors feel free to give your own perspective. ―[[User:Koavf|Justin (<span style="color:grey">ko'''a'''<span style="color:black">v</span>f</span>)]]<span style="color:red">❤[[User talk:Koavf|T]]☮[[Special:Contributions/Koavf|C]]☺[[Special:Emailuser/Koavf|M]]☯</span> 06:13, 14 May 2026 (UTC) :::Thanks, Justin — it is food for thought. :::In attempting to understand how we've arrived here, I've summarised some of the background on this page: [[Wikinews]]. :::Perhaps it could be helpful to flesh out more of the vision / ideas / possibilities / challenges on that page? -- [[User:Jtneill|Jtneill]] - <small>[[User talk:Jtneill|Talk]] - [[Special:Contributions/Jtneill|c]]</small> 11:49, 14 May 2026 (UTC) :::*Having given it some thought, in principle, I support hosting [[citizen journalism]] on Wikiversity where it is clearly connected to a learning project and/or constitutes original research, both of which align strongly with [[Wikiversity:Mission|Wikiversity’s educational mission]]. :::*My chief concern is the potential for news content that is not clearly linked to the purpose of Wikiversity. To avoid this, some community-agreed guidelines would be prudent. These need not be overly restrictive; they should support boldness and experimentation while helping ensure alignment with Wikiversity's purpose. :::*Given the reported low and declining activity on Wikinews, it seems unlikely that English Wikiversity would be overwhelmed by an influx of news-related editing. My impression is that English Wikinews was the most active edition, but even so, many contributors are likely to disperse to other projects or cease editing altogether. A modest migration of interested editors to Wikiversity seems manageable. :::*At this stage, I do not think a dedicated namespace is necessary. Subpages under [[Wikinews]] or nested pages under relevant learning or research projects, or user-space draft pages should be suitable. I agree that [[Wikijournal]] offers a useful model, as do several existing course structures on Wikiversity. :::*I support [[User:Koavf]]’s suggestions about framing Wikinews activity explicitly around learning. This would create a distinctive space for experimenting with collaborative news production in ways that are pedagogically meaningful. I agree that the [[journalism studies and Wikinews]] project developed by David and Leigh Blackall through the University of Wollongong is an excellent example of the intersection between Wikiversity and Wikinews. The [[Wikinews]] page could evolve into a hub for such projects. :::*I've tidied the [[:Category:Wikinews|Wikinews category]] and merged some content into the [[Wikinews]] page. As part of a reinvigoration effort, please review these and related resources such as [[:Category:Journalism]] and [[School:Journalism]]. :::*A further argument in favour of this initiative is that Wikipedia explicitly excludes both news reporting and original research. So, there is value in maintaining spaces within the Wikimedia ecosystem where these forms of knowledge production can be openly developed and curated. Such work can, in turn, generate valuable evidence and source material that may later inform Wikipedia articles. :::*The closure of WMF-hosted Wikinews does not imply that open wiki-based news curation lacks value. Indeed, the closure documentation appears supportive of experimentation with alternative news models across Wikimedia projects, including through Wikipedia and Wikidata. In that context, Wikiversity seems a natural home for a Wikinews experiment, provided it is clearly grounded in learning and/or research. :::-- [[User:Jtneill|Jtneill]] - <small>[[User talk:Jtneill|Talk]] - [[Special:Contributions/Jtneill|c]]</small> 11:39, 15 May 2026 (UTC) My understanding towards Wikinews' failure is that everything takes too long to be approved for the publish status, which means that any breaking news would have already become days-old stale news. Wikinews has a brand recognition (for right or wrong reasons) than Wikiversity and I wonder how effective Wikiversity can attract the "Wikinews refugees" to edit here. And just a quick note on the governance. Since each Wikiversity language operates independently, each language has to vote & adopt this proposal independently.

[[User:Juandev|Juandev]] ([[User talk:Juandev|discuss]] • [[Special:Contributions/Juandev|contribs]]) 19:14, 1 April 2026 (UTC) :Wikiversity's biggest issue in recent times was the hosting of low-quality, trash content. Thankfully we've done a great job in removing pseudoscience and other embarrassingly trash content (Wikidebates, for example), but the biggest concern moving forward is proper maintenance IMO. I've caught several pseudoscience pages being created within the last few months that could easily have flown under the radar (ex, [[The Kelemen Dilemma: Causal Collapse and Axiomatic Instability]]), so I'd urge our custodians/curators to be on the lookout for this type of content. Usually an AI-overview can point this type of content out relatively well. :In terms of visibility, I believe Wikiversity is a high-traffic project. I remember my [[Mathematical Properties]] showing up on the first page of Google when searching up "math properties" for the longest time (and is still showing up in the first page 'till this day!). Besides, Wikinews hosted a lot of short-term content (the nature of news articles), while Wikiversity hosts content that can still be useful a decade later (ex, [[A Reader's Guide to Annotation]]). :I think we are on a better path than we were a few months ago, and I do want to thank everyone here who has been helping out with maintaining our website! —[[User:Atcovi|Atcovi]] [[User talk:Atcovi|(Talk]] - [[Special:Contributions/Atcovi|Contribs)]] 20:48, 1 April 2026 (UTC) :For what it's worth, the group that did that study has since disbanded, so no one is monitoring the other sister projects in the same way.

Your questions are still worth addressing, but I just wanted to cut off any concern at the pass about Wikiversity being in the same precarious situation. Wikiversity is definitely the biggest "lagging behind" or "failure" project now that Wikinews is being shuttered, but I don't see any near- or medium-term pathway to closing Wikiversity. —[[User:Koavf|Justin (<span style="color:grey">ko'''a'''vf</span>)]]<span style="color:red">❤[[User talk:Koavf|T]]☮[[Special:Contributions/Koavf|C]]☺[[Special:Emailuser/Koavf|M]]☯</span> 00:46, 2 April 2026 (UTC) :[[w:en:Wikipedia:Wikipedia Signpost/2026-03-31/News and notes|Entirety of Wikinews to be shut down]] (Wikipedia Signpost) -- [[User:Jtneill|Jtneill]] - <small>[[User talk:Jtneill|Talk]] - [[Special:Contributions/Jtneill|c]]</small> 02:03, 11 April 2026 (UTC) == Action Required: Update templates/modules for electoral maps (Migrating from P1846 to P14226) == Hello everyone, This is a notice regarding an ongoing data migration on Wikidata that may affect your election-related templates and Lua modules (such as <code>Module:Itemgroup/list</code>). '''The Change:'''<br /> Currently, many templates pull electoral maps from Wikidata using the property [[:d:Property:P1846|P1846]], combined with the qualifier [[:d:Property:P180|P180]]: [[:d:Q19571328|Q19571328]].

'''What You Need To Do:'''<br /> To ensure your templates and infoboxes do not break or lose their maps, please update your local code to fetch data from [[:d:Property:P14226|P14226]] instead of the old [[:d:Property:P1846|P1846]] + [[:d:Property:P180|P180]] structure.

'''Deadline:'''<br /> We are temporarily retaining the old data on [[:d:Property:P1846|P1846]] to allow for a smooth transition. However, to complete the data cleanup on Wikidata, the old [[:d:Property:P1846|P1846]] statements will be removed after '''May 1, 2026'''.

What I've called it so far is "The Neurodiversity-inspired Idea". At other times I used more sensationalist wording but here on Wikiversity I don't dare do that. I actually woke up with thinking about putting this into my userspace draft: "Personal Observations Made By Meeting Autistic and Non-Autistic Adults". My ultimate goal is to stop blathering about my "idea" to friend and family without feeling my "methodology" is going into any progressive direction whatsoever. My latest encounter was somewhat constructive though. A friend of a friend who worked with people presenting ideas in attempting to getting grants. I don't want a grant. I just want to figure out how I can express my "idea" in a way so that I can more clearly figure out what flaws it got. At the same time I tend to overthink.

'''If I don't receive a reply to this in 1 week's time I will begin to explore this "idea" into my userspace''' unless you replied and refrained me from doing so, of course. Then maybe after "developing it there" I might reference it to you another future time here in the Colloquium, with my "idea" still in my userspace draft. This "idea" is sort of a burden, I'm happy I've made the choice to get rid of it and hopefully move on with my life, unless there is something to this "idea". My failure is probably evident: I feel I haven't told you anything. Same happened to when I talked to friends and family. In danger of overthinking it further I'll publish this right now.

Is there anyone here who is interested for Neurodiversity to be "something more" than it already is? Does anyone here consider Neurodiversity one of the "harder topics" to work on or discuss? Does anyone here have an opinion about the [[Neurodiversity Movement]]? So these questions don't appear like "out of a vacuum" I can tell you a bit about my background: Many years ago I got a psychiatric diagnosis "Asperger's". After I stepped out of the office and my Äsperger's was 'concluded', I stepped out into the street and thought my first negative thought(but the positive thought followed after). The thought was about concentration camps in the second world war and that the world seemed to be going into the direction of "labeling others". I was unsure whether this was "real science" and sort of "challenged myself" to make up my own mind after meeting people that had been given this diagnosis. The more adults with this diagnosis I met the more I started seeing "patterns". Was it a coincidence that the first person with Asperger's I met reminded me about my father later after I had plenty of times of experience with interacting with him? None of the people I interacted with online through IRC text chat...I felt I got any clue about how "their brains work". Only when I met one person from the Asperger's chat community in person we both realized that whatever we experienced was akin to the "chaos theory". He told me about "chaos theory" while I didn't know even what that term meant but I guess I 'read between the lines'. My question that I linger on still today is "did he understand about me what I think I understood about him?"? That our brains had the same configuration? Most autistic adults who meet other autistic adults usually get disappointed. They think the diagnosis will help them meet somebody like themselves and then they realize the great diversity in the autistic spectrum created by Psychiatry. I later stopped interacting with autistic communities that much, I felt that it did not benefit me. Also Neurodiversity's "neurotypes" interested me for a while until I realized I had "misunderstood everything" about them and how they are used in the Neurodiversity Movement or "Neurodiversity community" if that even can precisely be defined? I doubt it but if you want to contribute to the [[Neurodiversity Movement]]. My previous attempts failed as I got more and more confused. I think a community project needs a community. With a lack of that I don't think it is worth my time. If any of you would like to work on that project let me know on my talk page. So I was kinda lost and was talking to my friend and psychologist and I realized if I never talk about my idea to anyone in a "comprehensive way" or show that it matters to me nothing is going to ever happen. So I started talking about my "idea" more. Nobody could understand the "idea" because I had not developed my skills regarding where to start...although the process had already started "automatically" and that's why I often think of "well my brain sort of activated me". I don't feel like I did have a plan and this idea happened. It happened "by itself". My brain reacted to what I was seeing in a video or stream. I value interaction highly in this idea. I think it would be helpful to make a community of people who are not paranoid about stuff that can express itself like "don't analyze me!", "don't compare me to anyone!". On the contrary, more often than not those adults who were diagnosed were actually openly comparing themselves with each other and I think that is healthy in a "science" way if done the "right way" which probably means "Do no harm". I found video material is important but I'm very unsure if uploading own video material to Wikimedia Commons would constitute a "reasonable" use of the resources there. Maybe somebody here needs to ask more questions to me that I should answer before that happens. I also know the '''be bold''' so I could just do what I think might be ok. Though I work better in a group as long as I know what "group configurations" help me. This is in a non-profit way. Since the state supported me this might be a way I am trying to "give back" to the state and "the world". May seem overly ambitious and crazy but this thing gives me energy. It gives me hope when trying to develop this idea.

Another was the lack of activity, which can be ameliorated by having it be part of an existing project instead of its own domain (e.g. some editions of Wikipedia host their own Wikinews already and those projects were not impacted by the closure). :* Are any changes to the scope of Wikinews proposed? ::*Not at this juncture. I would also propose as far as implemention goes that we would request a new namespace and that the material be more-or-less sequestered into its own ongoing project, like Wikijournal is or like the Cookbook and Wikijunior are at our sister [[:b:]]. :* How does [[Wikinews]] fit with the [[Wikiversity:Mission]]? What aligns well? Where might there be tension? :** e.g., I'm not sure that a page like [[Story/Manchester City moves two points behind Arsenal]] in and of itself will serve as an educational resource. ::*The process of citizen journalists practicing their craft in real-time and collaborating with others to do so is itself an education activity. We would essentially be hosting a real-time experiment in citizen journalism, online communities, and collaborative learning in addition to the prospect of spreading educational information from someone actually reading the news. I would propose that we could also make a more deliberate attempt to engage with learning <em>about</em> what does and doesn't work with collaborative news writing by experimentation (e.g. audio news, syndicating to other sites, incorporating freely-licensed news from other sources, writing hyper-local news, writing briefs versus longer-term reportage) and also seeing if the problems noted in the Task Force report that recommended closure can be overcome. Note that we have already done some local investigation about and learning about wiki-based journalism on Wikinews here at [[Journalism studies and Wikinews]]. We could continue that learning and refine the process, including incorporating journalism students from universities. As for tensions, Wikinews is the only sister project that must be done with a quick turn-around: if you take a long time to [[:s:|transcribe a book]], that's just how long it takes, but if you take a long time to write news, it ceases to be news entirely. Wikiversity has been a very slow-growing project that has definitely had some successes but has generally come together over a long period with most learning resources being individual passion projects (or sometimes, frankly, crankery) which would not work with collaborative news that requires more than just a single editor writing whatever he feels like. ::Please let me know any other questions/concerns and any other editors feel free to give your own perspective. ―[[User:Koavf|Justin (<span style="color:grey">ko'''a'''<span style="color:black">v</span>f</span>)]]<span style="color:red">❤[[User talk:Koavf|T]]☮[[Special:Contributions/Koavf|C]]☺[[Special:Emailuser/Koavf|M]]☯</span> 06:13, 14 May 2026 (UTC) :::Thanks, Justin — it is food for thought. :::In attempting to understand how we've arrived here, I've summarised some of the background on this page: [[Wikinews]]. :::Perhaps it could be helpful to flesh out more of the vision / ideas / possibilities / challenges on that page? -- [[User:Jtneill|Jtneill]] - <small>[[User talk:Jtneill|Talk]] - [[Special:Contributions/Jtneill|c]]</small> 11:49, 14 May 2026 (UTC) :::*Having given it some thought, in principle, I support hosting [[citizen journalism]] on Wikiversity where it is clearly connected to a learning project and/or constitutes original research, both of which align strongly with [[Wikiversity:Mission|Wikiversity’s educational mission]]. :::*My chief concern is the potential for news content that is not clearly linked to the purpose of Wikiversity. To avoid this, some community-agreed guidelines would be prudent. These need not be overly restrictive; they should support boldness and experimentation while helping ensure alignment with Wikiversity's purpose. :::*Given the reported low and declining activity on Wikinews, it seems unlikely that English Wikiversity would be overwhelmed by an influx of news-related editing. My impression is that English Wikinews was the most active edition, but even so, many contributors are likely to disperse to other projects or cease editing altogether. A modest migration of interested editors to Wikiversity seems manageable. :::*At this stage, I do not think a dedicated namespace is necessary. Subpages under [[Wikinews]] or nested pages under relevant learning or research projects, or user-space draft pages should be suitable. I agree that [[Wikijournal]] offers a useful model, as do several existing course structures on Wikiversity. :::*I support [[User:Koavf]]’s suggestions about framing Wikinews activity explicitly around learning. This would create a distinctive space for experimenting with collaborative news production in ways that are pedagogically meaningful. I agree that the [[journalism studies and Wikinews]] project developed by David and Leigh Blackall through the University of Wollongong is an excellent example of the intersection between Wikiversity and Wikinews. The [[Wikinews]] page could evolve into a hub for such projects. :::*I've tidied the [[:Category:Wikinews|Wikinews category]] and merged some content into the [[Wikinews]] page. As part of a reinvigoration effort, please review these and related resources such as [[:Category:Journalism]] and [[School:Journalism]]. :::*A further argument in favour of this initiative is that Wikipedia explicitly excludes both news reporting and original research. So, there is value in maintaining spaces within the Wikimedia ecosystem where these forms of knowledge production can be openly developed and curated. Such work can, in turn, generate valuable evidence and source material that may later inform Wikipedia articles. :::*The closure of WMF-hosted Wikinews does not imply that open wiki-based news curation lacks value. Indeed, the closure documentation appears supportive of experimentation with alternative news models across Wikimedia projects, including through Wikipedia and Wikidata. In that context, Wikiversity seems a natural home for a Wikinews experiment, provided it is clearly grounded in learning and/or research. :::-- [[User:Jtneill|Jtneill]] - <small>[[User talk:Jtneill|Talk]] - [[Special:Contributions/Jtneill|c]]</small> 11:39, 15 May 2026 (UTC) My understanding towards Wikinews' failure is that everything takes too long to be approved for the publish status, which means that any breaking news would have already become days-old stale news. Wikinews has a brand recognition (for right or wrong reasons) than Wikiversity and I wonder how effective Wikiversity can attract the "Wikinews refugees" to edit here. And just a quick note on the governance. Since each Wikiversity language operates independently, each language has to vote & adopt this proposal independently.

[[User:Juandev|Juandev]] ([[User talk:Juandev|discuss]] • [[Special:Contributions/Juandev|contribs]]) 19:14, 1 April 2026 (UTC) :Wikiversity's biggest issue in recent times was the hosting of low-quality, trash content. Thankfully we've done a great job in removing pseudoscience and other embarrassingly trash content (Wikidebates, for example), but the biggest concern moving forward is proper maintenance IMO. I've caught several pseudoscience pages being created within the last few months that could easily have flown under the radar (ex, [[The Kelemen Dilemma: Causal Collapse and Axiomatic Instability]]), so I'd urge our custodians/curators to be on the lookout for this type of content. Usually an AI-overview can point this type of content out relatively well. :In terms of visibility, I believe Wikiversity is a high-traffic project. I remember my [[Mathematical Properties]] showing up on the first page of Google when searching up "math properties" for the longest time (and is still showing up in the first page 'till this day!). Besides, Wikinews hosted a lot of short-term content (the nature of news articles), while Wikiversity hosts content that can still be useful a decade later (ex, [[A Reader's Guide to Annotation]]). :I think we are on a better path than we were a few months ago, and I do want to thank everyone here who has been helping out with maintaining our website! —[[User:Atcovi|Atcovi]] [[User talk:Atcovi|(Talk]] - [[Special:Contributions/Atcovi|Contribs)]] 20:48, 1 April 2026 (UTC) :For what it's worth, the group that did that study has since disbanded, so no one is monitoring the other sister projects in the same way. Additionally, Wikinews had some catastrophic server issues due to the maintenance of [[:m:Extension:DynamicPageList]] which don't apply here. Your questions are still worth addressing, but I just wanted to cut off any concern at the pass about Wikiversity being in the same precarious situation. Wikiversity is definitely the biggest "lagging behind" or "failure" project now that Wikinews is being shuttered, but I don't see any near- or medium-term pathway to closing Wikiversity. —[[User:Koavf|Justin (<span style="color:grey">ko'''a'''vf</span>)]]<span style="color:red">❤[[User talk:Koavf|T]]☮[[Special:Contributions/Koavf|C]]☺[[Special:Emailuser/Koavf|M]]☯</span> 00:46, 2 April 2026 (UTC) :[[w:en:Wikipedia:Wikipedia Signpost/2026-03-31/News and notes|Entirety of Wikinews to be shut down]] (Wikipedia Signpost) -- [[User:Jtneill|Jtneill]] - <small>[[User talk:Jtneill|Talk]] - [[Special:Contributions/Jtneill|c]]</small> 02:03, 11 April 2026 (UTC) == Action Required: Update templates/modules for electoral maps (Migrating from P1846 to P14226) == Hello everyone, This is a notice regarding an ongoing data migration on Wikidata that may affect your election-related templates and Lua modules (such as <code>Module:Itemgroup/list</code>). '''The Change:'''<br /> Currently, many templates pull electoral maps from Wikidata using the property [[:d:Property:P1846|P1846]], combined with the qualifier [[:d:Property:P180|P180]]: [[:d:Q19571328|Q19571328]].

'''What You Need To Do:'''<br /> To ensure your templates and infoboxes do not break or lose their maps, please update your local code to fetch data from [[:d:Property:P14226|P14226]] instead of the old [[:d:Property:P1846|P1846]] + [[:d:Property:P180|P180]] structure. A [[m:Wikidata/Property Migration: P1846 to P14226/List|list of pages]] was generated using Wikimedia Global Search. '''Deadline:'''<br /> We are temporarily retaining the old data on [[:d:Property:P1846|P1846]] to allow for a smooth transition. However, to complete the data cleanup on Wikidata, the old [[:d:Property:P1846|P1846]] statements will be removed after '''May 1, 2026'''. Please update your modules and templates before this date to prevent any disruption to your wiki's election articles. Let us know if you have any questions or need assistance with the query logic.

What I've called it so far is "The Neurodiversity-inspired Idea". At other times I used more sensationalist wording but here on Wikiversity I don't dare do that. I actually woke up with thinking about putting this into my userspace draft: "Personal Observations Made By Meeting Autistic and Non-Autistic Adults". My ultimate goal is to stop blathering about my "idea" to friend and family without feeling my "methodology" is going into any progressive direction whatsoever. My latest encounter was somewhat constructive though. A friend of a friend who worked with people presenting ideas in attempting to getting grants. I don't want a grant. I just want to figure out how I can express my "idea" in a way so that I can more clearly figure out what flaws it got. At the same time I tend to overthink. If anyone thinks etherpad might be a good place and considering Wikimedia already got an etherpad at https://etherpad.wikimedia.org/ if anyone feels like they know me better in the future feel free to suggest a "session" on etherpad. '''If I don't receive a reply to this in 1 week's time I will begin to explore this "idea" into my userspace''' unless you replied and refrained me from doing so, of course. Then maybe after "developing it there" I might reference it to you another future time here in the Colloquium, with my "idea" still in my userspace draft. This "idea" is sort of a burden, I'm happy I've made the choice to get rid of it and hopefully move on with my life, unless there is something to this "idea". My failure is probably evident: I feel I haven't told you anything. Same happened to when I talked to friends and family. In danger of overthinking it further I'll publish this right now.

Is there anyone here who is interested for Neurodiversity to be "something more" than it already is? Does anyone here consider Neurodiversity one of the "harder topics" to work on or discuss? Does anyone here have an opinion about the [[Neurodiversity Movement]]? So these questions don't appear like "out of a vacuum" I can tell you a bit about my background: Many years ago I got a psychiatric diagnosis "Asperger's". After I stepped out of the office and my Äsperger's was 'concluded', I stepped out into the street and thought my first negative thought(but the positive thought followed after). The thought was about concentration camps in the second world war and that the world seemed to be going into the direction of "labeling others". I was unsure whether this was "real science" and sort of "challenged myself" to make up my own mind after meeting people that had been given this diagnosis. The more adults with this diagnosis I met the more I started seeing "patterns". Was it a coincidence that the first person with Asperger's I met reminded me about my father later after I had plenty of times of experience with interacting with him? None of the people I interacted with online through IRC text chat...I felt I got any clue about how "their brains work". Only when I met one person from the Asperger's chat community in person we both realized that whatever we experienced was akin to the "chaos theory". He told me about "chaos theory" while I didn't know even what that term meant but I guess I 'read between the lines'. My question that I linger on still today is "did he understand about me what I think I understood about him?"? That our brains had the same configuration? Most autistic adults who meet other autistic adults usually get disappointed. They think the diagnosis will help them meet somebody like themselves and then they realize the great diversity in the autistic spectrum created by Psychiatry. I later stopped interacting with autistic communities that much, I felt that it did not benefit me. Also Neurodiversity's "neurotypes" interested me for a while until I realized I had "misunderstood everything" about them and how they are used in the Neurodiversity Movement or "Neurodiversity community" if that even can precisely be defined? I doubt it but if you want to contribute to the [[Neurodiversity Movement]]. My previous attempts failed as I got more and more confused. I think a community project needs a community. With a lack of that I don't think it is worth my time. If any of you would like to work on that project let me know on my talk page. So I was kinda lost and was talking to my friend and psychologist and I realized if I never talk about my idea to anyone in a "comprehensive way" or show that it matters to me nothing is going to ever happen. So I started talking about my "idea" more. Nobody could understand the "idea" because I had not developed my skills regarding where to start...although the process had already started "automatically" and that's why I often think of "well my brain sort of activated me". I don't feel like I did have a plan and this idea happened. It happened "by itself". My brain reacted to what I was seeing in a video or stream. I value interaction highly in this idea. I think it would be helpful to make a community of people who are not paranoid about stuff that can express itself like "don't analyze me!", "don't compare me to anyone!". On the contrary, more often than not those adults who were diagnosed were actually openly comparing themselves with each other and I think that is healthy in a "science" way if done the "right way" which probably means "Do no harm". I found video material is important but I'm very unsure if uploading own video material to Wikimedia Commons would constitute a "reasonable" use of the resources there. Maybe somebody here needs to ask more questions to me that I should answer before that happens. I also know the '''be bold''' so I could just do what I think might be ok. Though I work better in a group as long as I know what "group configurations" help me. This is in a non-profit way. Since the state supported me this might be a way I am trying to "give back" to the state and "the world". May seem overly ambitious and crazy but this thing gives me energy. It gives me hope when trying to develop this idea.

Another was the lack of activity, which can be ameliorated by having it be part of an existing project instead of its own domain (e.g. some editions of Wikipedia host their own Wikinews already and those projects were not impacted by the closure). :* Are any changes to the scope of Wikinews proposed? ::*Not at this juncture. I would also propose as far as implemention goes that we would request a new namespace and that the material be more-or-less sequestered into its own ongoing project, like Wikijournal is or like the Cookbook and Wikijunior are at our sister [[:b:]]. :* How does [[Wikinews]] fit with the [[Wikiversity:Mission]]? What aligns well? Where might there be tension? :** e.g., I'm not sure that a page like [[Story/Manchester City moves two points behind Arsenal]] in and of itself will serve as an educational resource. ::*The process of citizen journalists practicing their craft in real-time and collaborating with others to do so is itself an education activity. We would essentially be hosting a real-time experiment in citizen journalism, online communities, and collaborative learning in addition to the prospect of spreading educational information from someone actually reading the news. I would propose that we could also make a more deliberate attempt to engage with learning <em>about</em> what does and doesn't work with collaborative news writing by experimentation (e.g. audio news, syndicating to other sites, incorporating freely-licensed news from other sources, writing hyper-local news, writing briefs versus longer-term reportage) and also seeing if the problems noted in the Task Force report that recommended closure can be overcome. Note that we have already done some local investigation about and learning about wiki-based journalism on Wikinews here at [[Journalism studies and Wikinews]]. We could continue that learning and refine the process, including incorporating journalism students from universities. As for tensions, Wikinews is the only sister project that must be done with a quick turn-around: if you take a long time to [[:s:|transcribe a book]], that's just how long it takes, but if you take a long time to write news, it ceases to be news entirely. Wikiversity has been a very slow-growing project that has definitely had some successes but has generally come together over a long period with most learning resources being individual passion projects (or sometimes, frankly, crankery) which would not work with collaborative news that requires more than just a single editor writing whatever he feels like. ::Please let me know any other questions/concerns and any other editors feel free to give your own perspective. ―[[User:Koavf|Justin (<span style="color:grey">ko'''a'''<span style="color:black">v</span>f</span>)]]<span style="color:red">❤[[User talk:Koavf|T]]☮[[Special:Contributions/Koavf|C]]☺[[Special:Emailuser/Koavf|M]]☯</span> 06:13, 14 May 2026 (UTC) :::Thanks, Justin — it is food for thought. :::In attempting to understand how we've arrived here, I've summarised some of the background on this page: [[Wikinews]]. :::Perhaps it could be helpful to flesh out more of the vision / ideas / possibilities / challenges on that page? -- [[User:Jtneill|Jtneill]] - <small>[[User talk:Jtneill|Talk]] - [[Special:Contributions/Jtneill|c]]</small> 11:49, 14 May 2026 (UTC) :::*Having given it some thought, in principle, I support hosting [[citizen journalism]] on Wikiversity where it is clearly connected to a learning project and/or constitutes original research, both of which align strongly with [[Wikiversity:Mission|Wikiversity’s educational mission]]. :::*My chief concern is the potential for news content that is not clearly linked to the purpose of Wikiversity. To avoid this, some community-agreed guidelines would be prudent. These need not be overly restrictive; they should support boldness and experimentation while helping ensure alignment with Wikiversity's purpose. :::*Given the reported low and declining activity on Wikinews, it seems unlikely that English Wikiversity would be overwhelmed by an influx of news-related editing. My impression is that English Wikinews was the most active edition, but even so, many contributors are likely to disperse to other projects or cease editing altogether. A modest migration of interested editors to Wikiversity seems manageable. :::*At this stage, I do not think a dedicated namespace is necessary. Subpages under [[Wikinews]] or nested pages under relevant learning or research projects, or user-space draft pages should be suitable. I agree that [[Wikijournal]] offers a useful model, as do several existing course structures on Wikiversity. :::*I support [[User:Koavf]]’s suggestions about framing Wikinews activity explicitly around learning. This would create a distinctive space for experimenting with collaborative news production in ways that are pedagogically meaningful. I agree that the [[journalism studies and Wikinews]] project developed by David and Leigh Blackall through the University of Wollongong is an excellent example of the intersection between Wikiversity and Wikinews. The [[Wikinews]] page could evolve into a hub for such projects. :::*I've tidied the [[:Category:Wikinews|Wikinews category]] and merged some content into the [[Wikinews]] page. As part of a reinvigoration effort, please review these and related resources such as [[:Category:Journalism]] and [[School:Journalism]]. :::*A further argument in favour of this initiative is that Wikipedia explicitly excludes both news reporting and original research. So, there is value in maintaining spaces within the Wikimedia ecosystem where these forms of knowledge production can be openly developed and curated. Such work can, in turn, generate valuable evidence and source material that may later inform Wikipedia articles. :::*The closure of WMF-hosted Wikinews does not imply that open wiki-based news curation lacks value. Indeed, the closure documentation appears supportive of experimentation with alternative news models across Wikimedia projects, including through Wikipedia and Wikidata. In that context, Wikiversity seems a natural home for a Wikinews experiment, provided it is clearly grounded in learning and/or research. :::-- [[User:Jtneill|Jtneill]] - <small>[[User talk:Jtneill|Talk]] - [[Special:Contributions/Jtneill|c]]</small> 11:39, 15 May 2026 (UTC) My understanding towards Wikinews' failure is that everything takes too long to be approved for the publish status, which means that any breaking news would have already become days-old stale news. Wikinews has a brand recognition (for right or wrong reasons) than Wikiversity and I wonder how effective Wikiversity can attract the "Wikinews refugees" to edit here.

I proposed to quasi-delete, i.e. '''move to userspace''' of the main (or sole?) creator, {{User|KYPark}}. The page is organized a little bit like a dictionary. It makes it redundant to Wiktionary except that Wikiversity allows original research and there does seem to be original research there. Thus, its being organized as a dictionary would alone not necessarily be a problem. Where I see a problem is in the organization and execution/implementation. Consider [[Korean/Words/가다]], which seems rather typical of the subpages (some subpages are like categories and transclude the pages for individual words): * On the putative definition line, there is this: "한곳에서 다른 곳으로 장소를 이동하다", apparently(?) in Korean. That does not seem to fit well into the ''English'' Wikiversity. * There seems to be some original research into etymological relations between Korean and European languages in the "Comparatives" section (from what I recall, the English Wiktionary rejected this kind of content from KYPark). Admittedly, it is marked using "This is a primary, secondary and/or original Eurasiatic research project at Wikiversity", so it could be tolerable, but even so, one has to wonder whether Wikiversity wants this kind of fringe science/research or outright pseudo-science. ** Fringe science: fringe physics has been moved to user space before. This would be fringe etymology. But then, original research is allowed. Deletion is not required; moving to user space suffices, I think. Alternatively, one could at least rename the pages to make it clear from the title that this is not Wikiversity voice but rather KYPark voice, e.g. "Korean/Words (KYPark)/..." or "Korean/Words/KYPark/..." (recall the "Fedosin" pages featuring the name "Fedosin"). Methodology: I see almost no methodological notes spanning the words at [[Korean/Words]]. And yet, if this is original research inventing new etymological connections, surely there should be some general considerations/analysis on how to proceed and how that manner of procedure differs from mainstream etymology?

I am not sure about how to proceed, although I am inclined to move it out of mainspace = quasi-delete. I am looking forward to get input from others, especially curators and custodians. Some considerations: 1) There is perhaps no more appearance/suspicion of copyright violation, now that the ResearchGate (RG) article (of which this is a copy, perhaps an incomplete copy?) carries a license. 2) The article is not a complete replica from RG: at a minimum, it lacks images. The inserter could have continued editing the page in his user space before he uploads images, that is, before he finalizes the page for consumption, but that did not happen. I did not check whether the text is an exact one-to-one match; the article does not indicate anything in that regard. 3) The principle implied seems to be this: users should feel free to duplicate non-peer-reviewed articles from RG in English Wikiversity, perhaps to increase the Google search and LLM yield. I find this problematic, in part for the duplication. I would say: choose a venue and publish it there. If RG is not good enough for you as a publishing venue, choose Wikiversity instead, but not both? 4) There are some features that appear unduly promotional. There is a link to a dot com home page of the inserter of the article. I dot not know how we handle or should handle this, whether prohibit such a link, etc. This is perhaps not so much a call to quasi-deletion but a call to make it less promotional. 5) I cannot determine the value of such an article. It seems to be a pseudo-article describing someone's browser extension.

Therefore we strongly recommend that all maritime health persons learn how to use this excellent tool in their daily maritime health practice of all different types. There are good online courses for self-instruction on how to use Zotero.

For example, click here, click there, order this, buy that. : : There is no such intention, form, or terms on my info page. Just neutral information.

I think that if you had written a book on Life Science, you would have mentioned that as well. : : Most of the Info page is about my research and AIPA Method which is a valid contribution to psychology, consciousness studies, identity theory, and personality development.

In contrast, AIPA targets the structural relationship between the self and the mind, aiming at durable identity reconstruction rooted in Pure Awareness rather than symptom management. : : The central research question of the primary AIPA preprint is whether a structured, sequentially staged method can produce permanent identity reconstruction rooted in Pure Awareness, and how such a method compares to established approaches in scope, mechanism, and outcome. : : == Theoretical foundations == : The AIPA framework is grounded in the cognitive‑phenomenological tradition (e.g., McAdams, Varela, Metzinger, Erikson), contemporary consciousness science on minimal phenomenal experience, and qualitative methods advocacy in psychology. It builds directly on: :* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. :* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. :* Narrative identity and partial‑self models within personality and identity theory. : Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. : : == Experiential empiricism == : The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: :* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. :* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). :* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. :* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. : : All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. : : I believe this is a valid contribution to Wikiversity. : : Best regards, Senad [[User:Senad Dizdarević|Senad Dizdarević]] I suggest you check the deleted user page, and see for yourself if it is "spam" and "authority hack", or a legit author's page with one paragraph short presentation, while the rest of the page is about my research project.

The sources ''themselves'' don't even back up the claims. It's just used as proof for an established concept, where the user then uses this established concept to jump to an unsupported, laughable conclusion that is pulled out of thin air. It's utterly ridiculous to even consider such a page for mainspace since it clearly violates our [[Wikiversity:Verifiability]] policy.

It mentions a ''chance'' of "life there [a habitable exoplanet] might not be limited to microbes, but could include creatures as large and varied as the megalosauruses or microraptors that once roamed Earth.", but again, no justification to take this article as proof that "aliens may have visited us!". There's no mention of aliens visiting Earth anywhere in the article. Once again this is only proving the background premise, but not the unsupported, nonsensical "alien likelihood" argument that the author of this garbage page is trying to push so desperately. :#The Parker Solar Probe WP article does not even mention aliens either.

I proposed to quasi-delete, i.e. '''move to userspace''' of the main (or sole?) creator, {{User|KYPark}}. The page is organized a little bit like a dictionary. It makes it redundant to Wiktionary except that Wikiversity allows original research and there does seem to be original research there. Thus, its being organized as a dictionary would alone not necessarily be a problem. Where I see a problem is in the organization and execution/implementation. Consider [[Korean/Words/가다]], which seems rather typical of the subpages (some subpages are like categories and transclude the pages for individual words): * On the putative definition line, there is this: "한곳에서 다른 곳으로 장소를 이동하다", apparently(?) in Korean. That does not seem to fit well into the ''English'' Wikiversity. * There seems to be some original research into etymological relations between Korean and European languages in the "Comparatives" section (from what I recall, the English Wiktionary rejected this kind of content from KYPark). Admittedly, it is marked using "This is a primary, secondary and/or original Eurasiatic research project at Wikiversity", so it could be tolerable, but even so, one has to wonder whether Wikiversity wants this kind of fringe science/research or outright pseudo-science. ** Fringe science: fringe physics has been moved to user space before. This would be fringe etymology. But then, original research is allowed. Deletion is not required; moving to user space suffices, I think. Alternatively, one could at least rename the pages to make it clear from the title that this is not Wikiversity voice but rather KYPark voice, e.g. "Korean/Words (KYPark)/..." or "Korean/Words/KYPark/..." (recall the "Fedosin" pages featuring the name "Fedosin"). Methodology: I see almost no methodological notes spanning the words at [[Korean/Words]]. And yet, if this is original research inventing new etymological connections, surely there should be some general considerations/analysis on how to proceed and how that manner of procedure differs from mainstream etymology?

I am not sure about how to proceed, although I am inclined to move it out of mainspace = quasi-delete. I am looking forward to get input from others, especially curators and custodians. Some considerations: 1) There is perhaps no more appearance/suspicion of copyright violation, now that the ResearchGate (RG) article (of which this is a copy, perhaps an incomplete copy?) carries a license. 2) The article is not a complete replica from RG: at a minimum, it lacks images. The inserter could have continued editing the page in his user space before he uploads images, that is, before he finalizes the page for consumption, but that did not happen. I did not check whether the text is an exact one-to-one match; the article does not indicate anything in that regard. 3) The principle implied seems to be this: users should feel free to duplicate non-peer-reviewed articles from RG in English Wikiversity, perhaps to increase the Google search and LLM yield. I find this problematic, in part for the duplication. I would say: choose a venue and publish it there. If RG is not good enough for you as a publishing venue, choose Wikiversity instead, but not both? 4) There are some features that appear unduly promotional. There is a link to a dot com home page of the inserter of the article. I dot not know how we handle or should handle this, whether prohibit such a link, etc. This is perhaps not so much a call to quasi-deletion but a call to make it less promotional. 5) I cannot determine the value of such an article. It seems to be a pseudo-article describing someone's browser extension. Can someone do a better analysis? --[[User:Dan Polansky|Dan Polansky]] ([[User talk:Dan Polansky|discuss]] • [[Special:Contributions/Dan Polansky|contribs]]) 06:48, 8 October 2025 (UTC) :2) Images for Wikicommons are being created, it will take a lot of time. and the text is not an exact one-to-one match :3) I also mentioned that It was being created so that it is more accessible from mobile phone, which is not possible in RG or in Zenodo :Let me clarify the purpose of uploading it to different platforms :Zenodo - registration and to link DOI :RG - Self Archiving :Wikiversity - Accessible by anyone from any device.

The Zotero Program is just one of many scientific literature management programs, that should be used for these purposes. Of course one can live without such a database but it helps a lot and can save a lot of time that could be used for more interesting issues. Not only that, but it helps to create better publications and knowledge. Without this program it can be very time consuming to publish a scientific article with the requested style for the references. Further in daily practice when you want to collect and cite a few references for a specific evidence in a clinical colloquium and discussion, this program is excellent. Therefore we strongly recommend that all maritime health persons learn how to use this excellent tool in their daily maritime health practice of all different types. There are good online courses for self-instruction on how to use Zotero. For example this one: Zotero fast online course But in order to increase IMHAR´s collective scientific strength in the use of EBM we would like to give training sessions in every possible opportunity, IMHA Symposia, seminars and other types of meetings.

Before I could explain him the difference between the neutral information and advertising and promotion, he deleted my user page. Here is my answer I posted to the discussion today: : Hi, my About Me page is just an info page with the neutral as possible presentation of my work. : : There is a big difference between informing and advertising. Informing is neutrally stating that something exists and requiring no action, while advertising is a special communication form with intent to cause certain action from readers. For example, click here, click there, order this, buy that. : : There is no such intention, form, or terms on my info page. Just neutral information. I don't hide and I am not ashamed that I am write and author, and that is a part of the usual bio, including works. I checked your user page: "I graduated from the Czech University of Life Sciences in Prague and studied information science at the Faculty of Arts of Charles University." I think that if you had written a book on Life Science, you would have mentioned that as well. : : Most of the Info page is about my research and AIPA Method which is a valid contribution to psychology, consciousness studies, identity theory, and personality development. Actually, my paper '''AIPA Method: A Cognitive-Phenomenological Model for Identity Reconstruction and Stabilization in Pure Awareness''' is now in the peer review procedure at Journal of Consciousness Studies. : : Here is a part from the Wikiversity AIPA Method page in creation (waiting for the end of the time limit for new users): : == Introduction == : The AIPA Method addresses a gap in contemporary personal development and consciousness science: most evidence‑based approaches (CBT, MBSR, MBCT, standard meditation) operate at the level of mental content—reframing thoughts, observing them, or reducing their impact—rather than at the level of identity structure. In contrast, AIPA targets the structural relationship between the self and the mind, aiming at durable identity reconstruction rooted in Pure Awareness rather than symptom management. : : The central research question of the primary AIPA preprint is whether a structured, sequentially staged method can produce permanent identity reconstruction rooted in Pure Awareness, and how such a method compares to established approaches in scope, mechanism, and outcome. : : == Theoretical foundations == : The AIPA framework is grounded in the cognitive‑phenomenological tradition (e.g., McAdams, Varela, Metzinger, Erikson), contemporary consciousness science on minimal phenomenal experience, and qualitative methods advocacy in psychology. It builds directly on: :* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. :* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. :* Narrative identity and partial‑self models within personality and identity theory. : Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. : : == Experiential empiricism == : The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: :* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. :* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). :* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. :* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. : : All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. : : I believe this is a valid contribution to Wikiversity. : : Best regards, Senad [[User:Senad Dizdarević|Senad Dizdarević]] I suggest you check the deleted user page, and see for yourself if it is "spam" and "authority hack", or a legit author's page with one paragraph short presentation, while the rest of the page is about my research project.

It mentions a ''chance'' of "life there [a habitable exoplanet] might not be limited to microbes, but could include creatures as large and varied as the megalosauruses or microraptors that once roamed Earth.", but again, no justification to take this article as proof that "aliens may have visited us!".

I proposed to quasi-delete, i.e. '''move to userspace''' of the main (or sole?) creator, {{User|KYPark}}. The page is organized a little bit like a dictionary. It makes it redundant to Wiktionary except that Wikiversity allows original research and there does seem to be original research there. Thus, its being organized as a dictionary would alone not necessarily be a problem. Where I see a problem is in the organization and execution/implementation. Consider [[Korean/Words/가다]], which seems rather typical of the subpages (some subpages are like categories and transclude the pages for individual words): * On the putative definition line, there is this: "한곳에서 다른 곳으로 장소를 이동하다", apparently(?) in Korean. That does not seem to fit well into the ''English'' Wikiversity. * There seems to be some original research into etymological relations between Korean and European languages in the "Comparatives" section (from what I recall, the English Wiktionary rejected this kind of content from KYPark). Admittedly, it is marked using "This is a primary, secondary and/or original Eurasiatic research project at Wikiversity", so it could be tolerable, but even so, one has to wonder whether Wikiversity wants this kind of fringe science/research or outright pseudo-science. ** Fringe science: fringe physics has been moved to user space before. This would be fringe etymology. But then, original research is allowed. Deletion is not required; moving to user space suffices, I think. Alternatively, one could at least rename the pages to make it clear from the title that this is not Wikiversity voice but rather KYPark voice, e.g. "Korean/Words (KYPark)/..." or "Korean/Words/KYPark/..." (recall the "Fedosin" pages featuring the name "Fedosin"). Methodology: I see almost no methodological notes spanning the words at [[Korean/Words]]. And yet, if this is original research inventing new etymological connections, surely there should be some general considerations/analysis on how to proceed and how that manner of procedure differs from mainstream etymology?

I am not sure about how to proceed, although I am inclined to move it out of mainspace = quasi-delete. I am looking forward to get input from others, especially curators and custodians. Some considerations: 1) There is perhaps no more appearance/suspicion of copyright violation, now that the ResearchGate (RG) article (of which this is a copy, perhaps an incomplete copy?) carries a license. 2) The article is not a complete replica from RG: at a minimum, it lacks images. The inserter could have continued editing the page in his user space before he uploads images, that is, before he finalizes the page for consumption, but that did not happen. I did not check whether the text is an exact one-to-one match; the article does not indicate anything in that regard. 3) The principle implied seems to be this: users should feel free to duplicate non-peer-reviewed articles from RG in English Wikiversity, perhaps to increase the Google search and LLM yield. I find this problematic, in part for the duplication. I would say: choose a venue and publish it there. If RG is not good enough for you as a publishing venue, choose Wikiversity instead, but not both? 4) There are some features that appear unduly promotional. There is a link to a dot com home page of the inserter of the article. I dot not know how we handle or should handle this, whether prohibit such a link, etc. This is perhaps not so much a call to quasi-deletion but a call to make it less promotional. 5) I cannot determine the value of such an article. It seems to be a pseudo-article describing someone's browser extension.

The Zotero Program is just one of many scientific literature management programs, that should be used for these purposes. Of course one can live without such a database but it helps a lot and can save a lot of time that could be used for more interesting issues. Not only that, but it helps to create better publications and knowledge. Without this program it can be very time consuming to publish a scientific article with the requested style for the references. Further in daily practice when you want to collect and cite a few references for a specific evidence in a clinical colloquium and discussion, this program is excellent. Therefore we strongly recommend that all maritime health persons learn how to use this excellent tool in their daily maritime health practice of all different types. There are good online courses for self-instruction on how to use Zotero. For example this one: Zotero fast online course But in order to increase IMHAR´s collective scientific strength in the use of EBM we would like to give training sessions in every possible opportunity, IMHA Symposia, seminars and other types of meetings. The database is useful for personal purposes but especially also for collaborative aims. At the IMHAR meeting in Paris Oct 7th 2016 we will give an introduction to the program by showing how it can be used in the daily practice and discuss strength and weaknesses compared to other similar databases." : Even longer is e.g. [[IMHA Research Archives/Scientific litterature search, storage and use/Medicina Maritima - the Spanish scientific maritime health journal]]. : However, that does not mean these should be salvaged. --[[User:Dan Polansky|Dan Polansky]] ([[User talk:Dan Polansky|discuss]] • [[Special:Contributions/Dan Polansky|contribs]]) 07:53, 21 November 2025 (UTC) == [[Palliative medicine]] == Underdeveloped and has not been improved on since 2007.

It should not work, when the website is blacklisted. As of now, I am not seeing you to save page in main namespace, so try to save it without external links first. Then he wrote me another message: Well, I have analyzed your contribution to Wikiversity and I should point out here, that this project is not a place for advertising, so there is no way of promoting your books and authority this way. - probably referring to the intro of my About me page where I present me and my work. Before I could explain him the difference between the neutral information and advertising and promotion, he deleted my user page. Here is my answer I posted to the discussion today: : Hi, my About Me page is just an info page with the neutral as possible presentation of my work. : : There is a big difference between informing and advertising. Informing is neutrally stating that something exists and requiring no action, while advertising is a special communication form with intent to cause certain action from readers. For example, click here, click there, order this, buy that. : : There is no such intention, form, or terms on my info page. Just neutral information. I don't hide and I am not ashamed that I am write and author, and that is a part of the usual bio, including works. I checked your user page: "I graduated from the Czech University of Life Sciences in Prague and studied information science at the Faculty of Arts of Charles University." I think that if you had written a book on Life Science, you would have mentioned that as well. : : Most of the Info page is about my research and AIPA Method which is a valid contribution to psychology, consciousness studies, identity theory, and personality development. Actually, my paper '''AIPA Method: A Cognitive-Phenomenological Model for Identity Reconstruction and Stabilization in Pure Awareness''' is now in the peer review procedure at Journal of Consciousness Studies. : : Here is a part from the Wikiversity AIPA Method page in creation (waiting for the end of the time limit for new users): : == Introduction == : The AIPA Method addresses a gap in contemporary personal development and consciousness science: most evidence‑based approaches (CBT, MBSR, MBCT, standard meditation) operate at the level of mental content—reframing thoughts, observing them, or reducing their impact—rather than at the level of identity structure. In contrast, AIPA targets the structural relationship between the self and the mind, aiming at durable identity reconstruction rooted in Pure Awareness rather than symptom management. : : The central research question of the primary AIPA preprint is whether a structured, sequentially staged method can produce permanent identity reconstruction rooted in Pure Awareness, and how such a method compares to established approaches in scope, mechanism, and outcome. : : == Theoretical foundations == : The AIPA framework is grounded in the cognitive‑phenomenological tradition (e.g., McAdams, Varela, Metzinger, Erikson), contemporary consciousness science on minimal phenomenal experience, and qualitative methods advocacy in psychology. It builds directly on: :* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. :* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. :* Narrative identity and partial‑self models within personality and identity theory. : Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. : : == Experiential empiricism == : The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: :* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. :* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). :* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. :* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. : : All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. : : I believe this is a valid contribution to Wikiversity. : : Best regards, Senad [[User:Senad Dizdarević|Senad Dizdarević]] I suggest you check the deleted user page, and see for yourself if it is "spam" and "authority hack", or a legit author's page with one paragraph short presentation, while the rest of the page is about my research project.

The sources ''themselves'' don't even back up the claims. It's just used as proof for an established concept, where the user then uses this established concept to jump to an unsupported, laughable conclusion that is pulled out of thin air. It's utterly ridiculous to even consider such a page for mainspace since it clearly violates our [[Wikiversity:Verifiability]] policy. This is, once again, pseudoscientific content that has caused our website to reduce in quality over the last few years. :* Going source by source, we can see that: :#[https://web.archive.org/web/20250918011642/https://timesofindia.indiatimes.com/blogs/thebigd/compress-earths-history-into-24-hrs-humans-came-at-1158-pm-yet-killed-70-of-wildlife/ ‘Compress Earth’s history into 24 hrs. Humans came at 11:58 pm, yet killed 70% of wildlife’] is literally just a blog post which doesn't even mention aliens or extraterrestrial life. It just talks about Earth's history in accordance with the 24-hour metric of time, and the author tries to use this article as a 'piece in the puzzle' of aliens "possibly" visiting Earth... which, once again, is unsupported and is not backed up anywhere in the article. :#[https://web.archive.org/web/20250808053249/https://news.cornell.edu/stories/2023/11/jurassic-worlds-might-be-easier-spot-modern-earth The Cornell article does not even remotely support the idea that "aliens visited Earth"]. It mentions a ''chance'' of "life there [a habitable exoplanet] might not be limited to microbes, but could include creatures as large and varied as the megalosauruses or microraptors that once roamed Earth.", but again, no justification to take this article as proof that "aliens may have visited us!". There's no mention of aliens visiting Earth anywhere in the article. Once again this is only proving the background premise, but not the unsupported, nonsensical "alien likelihood" argument that the author of this garbage page is trying to push so desperately. :#The Parker Solar Probe WP article does not even mention aliens either. It follows the same issues as the previous argument. :And the other page this user complained about [https://en.wikiversity.org/wiki/User_talk:Atcovi#Deletion_of_educational_page_because_of_personal_opinion on my talk page] holds almost similar, maybe even more fatal mistakes, than this one.

I proposed to quasi-delete, i.e. '''move to userspace''' of the main (or sole?) creator, {{User|KYPark}}. The page is organized a little bit like a dictionary. It makes it redundant to Wiktionary except that Wikiversity allows original research and there does seem to be original research there. Thus, its being organized as a dictionary would alone not necessarily be a problem. Where I see a problem is in the organization and execution/implementation. Consider [[Korean/Words/가다]], which seems rather typical of the subpages (some subpages are like categories and transclude the pages for individual words): * On the putative definition line, there is this: "한곳에서 다른 곳으로 장소를 이동하다", apparently(?) in Korean. That does not seem to fit well into the ''English'' Wikiversity. * There seems to be some original research into etymological relations between Korean and European languages in the "Comparatives" section (from what I recall, the English Wiktionary rejected this kind of content from KYPark). Admittedly, it is marked using "This is a primary, secondary and/or original Eurasiatic research project at Wikiversity", so it could be tolerable, but even so, one has to wonder whether Wikiversity wants this kind of fringe science/research or outright pseudo-science. ** Fringe science: fringe physics has been moved to user space before. This would be fringe etymology. But then, original research is allowed. Deletion is not required; moving to user space suffices, I think. Alternatively, one could at least rename the pages to make it clear from the title that this is not Wikiversity voice but rather KYPark voice, e.g. "Korean/Words (KYPark)/..." or "Korean/Words/KYPark/..." (recall the "Fedosin" pages featuring the name "Fedosin"). Methodology: I see almost no methodological notes spanning the words at [[Korean/Words]]. And yet, if this is original research inventing new etymological connections, surely there should be some general considerations/analysis on how to proceed and how that manner of procedure differs from mainstream etymology?

I am not sure about how to proceed, although I am inclined to move it out of mainspace = quasi-delete. I am looking forward to get input from others, especially curators and custodians. Some considerations: 1) There is perhaps no more appearance/suspicion of copyright violation, now that the ResearchGate (RG) article (of which this is a copy, perhaps an incomplete copy?) carries a license. 2) The article is not a complete replica from RG: at a minimum, it lacks images. The inserter could have continued editing the page in his user space before he uploads images, that is, before he finalizes the page for consumption, but that did not happen. I did not check whether the text is an exact one-to-one match; the article does not indicate anything in that regard. 3) The principle implied seems to be this: users should feel free to duplicate non-peer-reviewed articles from RG in English Wikiversity, perhaps to increase the Google search and LLM yield. I find this problematic, in part for the duplication. I would say: choose a venue and publish it there. If RG is not good enough for you as a publishing venue, choose Wikiversity instead, but not both? 4) There are some features that appear unduly promotional. There is a link to a dot com home page of the inserter of the article. I dot not know how we handle or should handle this, whether prohibit such a link, etc. This is perhaps not so much a call to quasi-deletion but a call to make it less promotional. 5) I cannot determine the value of such an article. It seems to be a pseudo-article describing someone's browser extension. Can someone do a better analysis? --[[User:Dan Polansky|Dan Polansky]] ([[User talk:Dan Polansky|discuss]] • [[Special:Contributions/Dan Polansky|contribs]]) 06:48, 8 October 2025 (UTC) :2) Images for Wikicommons are being created, it will take a lot of time. and the text is not an exact one-to-one match :3) I also mentioned that It was being created so that it is more accessible from mobile phone, which is not possible in RG or in Zenodo :Let me clarify the purpose of uploading it to different platforms :Zenodo - registration and to link DOI :RG - Self Archiving :Wikiversity - Accessible by anyone from any device.

The Zotero Program is just one of many scientific literature management programs, that should be used for these purposes. Of course one can live without such a database but it helps a lot and can save a lot of time that could be used for more interesting issues. Not only that, but it helps to create better publications and knowledge. Without this program it can be very time consuming to publish a scientific article with the requested style for the references. Further in daily practice when you want to collect and cite a few references for a specific evidence in a clinical colloquium and discussion, this program is excellent. Therefore we strongly recommend that all maritime health persons learn how to use this excellent tool in their daily maritime health practice of all different types. There are good online courses for self-instruction on how to use Zotero. For example this one: Zotero fast online course But in order to increase IMHAR´s collective scientific strength in the use of EBM we would like to give training sessions in every possible opportunity, IMHA Symposia, seminars and other types of meetings. The database is useful for personal purposes but especially also for collaborative aims. At the IMHAR meeting in Paris Oct 7th 2016 we will give an introduction to the program by showing how it can be used in the daily practice and discuss strength and weaknesses compared to other similar databases." : Even longer is e.g. [[IMHA Research Archives/Scientific litterature search, storage and use/Medicina Maritima - the Spanish scientific maritime health journal]]. : However, that does not mean these should be salvaged. --[[User:Dan Polansky|Dan Polansky]] ([[User talk:Dan Polansky|discuss]] • [[Special:Contributions/Dan Polansky|contribs]]) 07:53, 21 November 2025 (UTC) == [[Palliative medicine]] == Underdeveloped and has not been improved on since 2007.

First, I asked him for help with "time limit for new users", and he replied - I should admit I dont know, what is "new user limit", but if filter blocks your page because of certain external link, you may force to save anyway and sometimes it works. It should not work, when the website is blacklisted. As of now, I am not seeing you to save page in main namespace, so try to save it without external links first. Then he wrote me another message: Well, I have analyzed your contribution to Wikiversity and I should point out here, that this project is not a place for advertising, so there is no way of promoting your books and authority this way. - probably referring to the intro of my About me page where I present me and my work. Before I could explain him the difference between the neutral information and advertising and promotion, he deleted my user page. Here is my answer I posted to the discussion today: : Hi, my About Me page is just an info page with the neutral as possible presentation of my work. : : There is a big difference between informing and advertising. Informing is neutrally stating that something exists and requiring no action, while advertising is a special communication form with intent to cause certain action from readers. For example, click here, click there, order this, buy that. : : There is no such intention, form, or terms on my info page. Just neutral information. I don't hide and I am not ashamed that I am write and author, and that is a part of the usual bio, including works. I checked your user page: "I graduated from the Czech University of Life Sciences in Prague and studied information science at the Faculty of Arts of Charles University." I think that if you had written a book on Life Science, you would have mentioned that as well. : : Most of the Info page is about my research and AIPA Method which is a valid contribution to psychology, consciousness studies, identity theory, and personality development. Actually, my paper '''AIPA Method: A Cognitive-Phenomenological Model for Identity Reconstruction and Stabilization in Pure Awareness''' is now in the peer review procedure at Journal of Consciousness Studies. : : Here is a part from the Wikiversity AIPA Method page in creation (waiting for the end of the time limit for new users): : == Introduction == : The AIPA Method addresses a gap in contemporary personal development and consciousness science: most evidence‑based approaches (CBT, MBSR, MBCT, standard meditation) operate at the level of mental content—reframing thoughts, observing them, or reducing their impact—rather than at the level of identity structure. In contrast, AIPA targets the structural relationship between the self and the mind, aiming at durable identity reconstruction rooted in Pure Awareness rather than symptom management. : : The central research question of the primary AIPA preprint is whether a structured, sequentially staged method can produce permanent identity reconstruction rooted in Pure Awareness, and how such a method compares to established approaches in scope, mechanism, and outcome. : : == Theoretical foundations == : The AIPA framework is grounded in the cognitive‑phenomenological tradition (e.g., McAdams, Varela, Metzinger, Erikson), contemporary consciousness science on minimal phenomenal experience, and qualitative methods advocacy in psychology. It builds directly on: :* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. :* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. :* Narrative identity and partial‑self models within personality and identity theory. : Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. : : == Experiential empiricism == : The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: :* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. :* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). :* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. :* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. : : All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. : : I believe this is a valid contribution to Wikiversity. : : Best regards, Senad [[User:Senad Dizdarević|Senad Dizdarević]] I suggest you check the deleted user page, and see for yourself if it is "spam" and "authority hack", or a legit author's page with one paragraph short presentation, while the rest of the page is about my research project.

It mentions a ''chance'' of "life there [a habitable exoplanet] might not be limited to microbes, but could include creatures as large and varied as the megalosauruses or microraptors that once roamed Earth.", but again, no justification to take this article as proof that "aliens may have visited us!". There's no mention of aliens visiting Earth anywhere in the article.

I proposed to quasi-delete, i.e. '''move to userspace''' of the main (or sole?) creator, {{User|KYPark}}. The page is organized a little bit like a dictionary. It makes it redundant to Wiktionary except that Wikiversity allows original research and there does seem to be original research there. Thus, its being organized as a dictionary would alone not necessarily be a problem. Where I see a problem is in the organization and execution/implementation. Consider [[Korean/Words/가다]], which seems rather typical of the subpages (some subpages are like categories and transclude the pages for individual words): * On the putative definition line, there is this: "한곳에서 다른 곳으로 장소를 이동하다", apparently(?) in Korean. That does not seem to fit well into the ''English'' Wikiversity. * There seems to be some original research into etymological relations between Korean and European languages in the "Comparatives" section (from what I recall, the English Wiktionary rejected this kind of content from KYPark). Admittedly, it is marked using "This is a primary, secondary and/or original Eurasiatic research project at Wikiversity", so it could be tolerable, but even so, one has to wonder whether Wikiversity wants this kind of fringe science/research or outright pseudo-science. ** Fringe science: fringe physics has been moved to user space before. This would be fringe etymology. But then, original research is allowed. Deletion is not required; moving to user space suffices, I think. Alternatively, one could at least rename the pages to make it clear from the title that this is not Wikiversity voice but rather KYPark voice, e.g. "Korean/Words (KYPark)/..." or "Korean/Words/KYPark/..." (recall the "Fedosin" pages featuring the name "Fedosin"). Methodology: I see almost no methodological notes spanning the words at [[Korean/Words]]. And yet, if this is original research inventing new etymological connections, surely there should be some general considerations/analysis on how to proceed and how that manner of procedure differs from mainstream etymology?

I am not sure about how to proceed, although I am inclined to move it out of mainspace = quasi-delete. I am looking forward to get input from others, especially curators and custodians. Some considerations: 1) There is perhaps no more appearance/suspicion of copyright violation, now that the ResearchGate (RG) article (of which this is a copy, perhaps an incomplete copy?) carries a license. 2) The article is not a complete replica from RG: at a minimum, it lacks images. The inserter could have continued editing the page in his user space before he uploads images, that is, before he finalizes the page for consumption, but that did not happen. I did not check whether the text is an exact one-to-one match; the article does not indicate anything in that regard. 3) The principle implied seems to be this: users should feel free to duplicate non-peer-reviewed articles from RG in English Wikiversity, perhaps to increase the Google search and LLM yield. I find this problematic, in part for the duplication. I would say: choose a venue and publish it there. If RG is not good enough for you as a publishing venue, choose Wikiversity instead, but not both? 4) There are some features that appear unduly promotional. There is a link to a dot com home page of the inserter of the article. I dot not know how we handle or should handle this, whether prohibit such a link, etc. This is perhaps not so much a call to quasi-deletion but a call to make it less promotional. 5) I cannot determine the value of such an article. It seems to be a pseudo-article describing someone's browser extension. Can someone do a better analysis? --[[User:Dan Polansky|Dan Polansky]] ([[User talk:Dan Polansky|discuss]] • [[Special:Contributions/Dan Polansky|contribs]]) 06:48, 8 October 2025 (UTC) :2) Images for Wikicommons are being created, it will take a lot of time. and the text is not an exact one-to-one match :3) I also mentioned that It was being created so that it is more accessible from mobile phone, which is not possible in RG or in Zenodo :Let me clarify the purpose of uploading it to different platforms :Zenodo - registration and to link DOI :RG - Self Archiving :Wikiversity - Accessible by anyone from any device.

Not only that, but it helps to create better publications and knowledge. Without this program it can be very time consuming to publish a scientific article with the requested style for the references. Further in daily practice when you want to collect and cite a few references for a specific evidence in a clinical colloquium and discussion, this program is excellent. Therefore we strongly recommend that all maritime health persons learn how to use this excellent tool in their daily maritime health practice of all different types. There are good online courses for self-instruction on how to use Zotero. For example this one: Zotero fast online course But in order to increase IMHAR´s collective scientific strength in the use of EBM we would like to give training sessions in every possible opportunity, IMHA Symposia, seminars and other types of meetings.

First, I asked him for help with "time limit for new users", and he replied - I should admit I dont know, what is "new user limit", but if filter blocks your page because of certain external link, you may force to save anyway and sometimes it works. It should not work, when the website is blacklisted. As of now, I am not seeing you to save page in main namespace, so try to save it without external links first. Then he wrote me another message: Well, I have analyzed your contribution to Wikiversity and I should point out here, that this project is not a place for advertising, so there is no way of promoting your books and authority this way. - probably referring to the intro of my About me page where I present me and my work. Before I could explain him the difference between the neutral information and advertising and promotion, he deleted my user page. Here is my answer I posted to the discussion today: : Hi, my About Me page is just an info page with the neutral as possible presentation of my work. : : There is a big difference between informing and advertising. Informing is neutrally stating that something exists and requiring no action, while advertising is a special communication form with intent to cause certain action from readers. For example, click here, click there, order this, buy that. : : There is no such intention, form, or terms on my info page. Just neutral information. I don't hide and I am not ashamed that I am write and author, and that is a part of the usual bio, including works. I checked your user page: "I graduated from the Czech University of Life Sciences in Prague and studied information science at the Faculty of Arts of Charles University." I think that if you had written a book on Life Science, you would have mentioned that as well. : : Most of the Info page is about my research and AIPA Method which is a valid contribution to psychology, consciousness studies, identity theory, and personality development. Actually, my paper '''AIPA Method: A Cognitive-Phenomenological Model for Identity Reconstruction and Stabilization in Pure Awareness''' is now in the peer review procedure at Journal of Consciousness Studies. : : Here is a part from the Wikiversity AIPA Method page in creation (waiting for the end of the time limit for new users): : == Introduction == : The AIPA Method addresses a gap in contemporary personal development and consciousness science: most evidence‑based approaches (CBT, MBSR, MBCT, standard meditation) operate at the level of mental content—reframing thoughts, observing them, or reducing their impact—rather than at the level of identity structure. In contrast, AIPA targets the structural relationship between the self and the mind, aiming at durable identity reconstruction rooted in Pure Awareness rather than symptom management. : : The central research question of the primary AIPA preprint is whether a structured, sequentially staged method can produce permanent identity reconstruction rooted in Pure Awareness, and how such a method compares to established approaches in scope, mechanism, and outcome. : : == Theoretical foundations == : The AIPA framework is grounded in the cognitive‑phenomenological tradition (e.g., McAdams, Varela, Metzinger, Erikson), contemporary consciousness science on minimal phenomenal experience, and qualitative methods advocacy in psychology. It builds directly on: :* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. :* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. :* Narrative identity and partial‑self models within personality and identity theory. : Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. : : == Experiential empiricism == : The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: :* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. :* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). :* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. :* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. : : All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. : : I believe this is a valid contribution to Wikiversity. : : Best regards, Senad [[User:Senad Dizdarević|Senad Dizdarević]] I suggest you check the deleted user page, and see for yourself if it is "spam" and "authority hack", or a legit author's page with one paragraph short presentation, while the rest of the page is about my research project.

I proposed to quasi-delete, i.e. '''move to userspace''' of the main (or sole?) creator, {{User|KYPark}}. The page is organized a little bit like a dictionary. It makes it redundant to Wiktionary except that Wikiversity allows original research and there does seem to be original research there. Thus, its being organized as a dictionary would alone not necessarily be a problem. Where I see a problem is in the organization and execution/implementation. Consider [[Korean/Words/가다]], which seems rather typical of the subpages (some subpages are like categories and transclude the pages for individual words): * On the putative definition line, there is this: "한곳에서 다른 곳으로 장소를 이동하다", apparently(?) in Korean. That does not seem to fit well into the ''English'' Wikiversity. * There seems to be some original research into etymological relations between Korean and European languages in the "Comparatives" section (from what I recall, the English Wiktionary rejected this kind of content from KYPark). Admittedly, it is marked using "This is a primary, secondary and/or original Eurasiatic research project at Wikiversity", so it could be tolerable, but even so, one has to wonder whether Wikiversity wants this kind of fringe science/research or outright pseudo-science. ** Fringe science: fringe physics has been moved to user space before. This would be fringe etymology. But then, original research is allowed. Deletion is not required; moving to user space suffices, I think. Alternatively, one could at least rename the pages to make it clear from the title that this is not Wikiversity voice but rather KYPark voice, e.g. "Korean/Words (KYPark)/..." or "Korean/Words/KYPark/..." (recall the "Fedosin" pages featuring the name "Fedosin"). Methodology: I see almost no methodological notes spanning the words at [[Korean/Words]]. And yet, if this is original research inventing new etymological connections, surely there should be some general considerations/analysis on how to proceed and how that manner of procedure differs from mainstream etymology?

I am not sure about how to proceed, although I am inclined to move it out of mainspace = quasi-delete. I am looking forward to get input from others, especially curators and custodians. Some considerations: 1) There is perhaps no more appearance/suspicion of copyright violation, now that the ResearchGate (RG) article (of which this is a copy, perhaps an incomplete copy?) carries a license. 2) The article is not a complete replica from RG: at a minimum, it lacks images. The inserter could have continued editing the page in his user space before he uploads images, that is, before he finalizes the page for consumption, but that did not happen. I did not check whether the text is an exact one-to-one match; the article does not indicate anything in that regard. 3) The principle implied seems to be this: users should feel free to duplicate non-peer-reviewed articles from RG in English Wikiversity, perhaps to increase the Google search and LLM yield. I find this problematic, in part for the duplication. I would say: choose a venue and publish it there. If RG is not good enough for you as a publishing venue, choose Wikiversity instead, but not both? 4) There are some features that appear unduly promotional. There is a link to a dot com home page of the inserter of the article. I dot not know how we handle or should handle this, whether prohibit such a link, etc. This is perhaps not so much a call to quasi-deletion but a call to make it less promotional. 5) I cannot determine the value of such an article. It seems to be a pseudo-article describing someone's browser extension. Can someone do a better analysis? --[[User:Dan Polansky|Dan Polansky]] ([[User talk:Dan Polansky|discuss]] • [[Special:Contributions/Dan Polansky|contribs]]) 06:48, 8 October 2025 (UTC) :2) Images for Wikicommons are being created, it will take a lot of time. and the text is not an exact one-to-one match :3) I also mentioned that It was being created so that it is more accessible from mobile phone, which is not possible in RG or in Zenodo :Let me clarify the purpose of uploading it to different platforms :Zenodo - registration and to link DOI :RG - Self Archiving :Wikiversity - Accessible by anyone from any device.

Not only that, but it helps to create better publications and knowledge. Without this program it can be very time consuming to publish a scientific article with the requested style for the references. Further in daily practice when you want to collect and cite a few references for a specific evidence in a clinical colloquium and discussion, this program is excellent. Therefore we strongly recommend that all maritime health persons learn how to use this excellent tool in their daily maritime health practice of all different types. There are good online courses for self-instruction on how to use Zotero. For example this one: Zotero fast online course But in order to increase IMHAR´s collective scientific strength in the use of EBM we would like to give training sessions in every possible opportunity, IMHA Symposia, seminars and other types of meetings. The database is useful for personal purposes but especially also for collaborative aims. At the IMHAR meeting in Paris Oct 7th 2016 we will give an introduction to the program by showing how it can be used in the daily practice and discuss strength and weaknesses compared to other similar databases." : Even longer is e.g. [[IMHA Research Archives/Scientific litterature search, storage and use/Medicina Maritima - the Spanish scientific maritime health journal]]. : However, that does not mean these should be salvaged. --[[User:Dan Polansky|Dan Polansky]] ([[User talk:Dan Polansky|discuss]] • [[Special:Contributions/Dan Polansky|contribs]]) 07:53, 21 November 2025 (UTC) == [[Palliative medicine]] == Underdeveloped and has not been improved on since 2007.

First, I asked him for help with "time limit for new users", and he replied - I should admit I dont know, what is "new user limit", but if filter blocks your page because of certain external link, you may force to save anyway and sometimes it works. It should not work, when the website is blacklisted. As of now, I am not seeing you to save page in main namespace, so try to save it without external links first. Then he wrote me another message: Well, I have analyzed your contribution to Wikiversity and I should point out here, that this project is not a place for advertising, so there is no way of promoting your books and authority this way. - probably referring to the intro of my About me page where I present me and my work. Before I could explain him the difference between the neutral information and advertising and promotion, he deleted my user page. Here is my answer I posted to the discussion today: : Hi, my About Me page is just an info page with the neutral as possible presentation of my work. : : There is a big difference between informing and advertising. Informing is neutrally stating that something exists and requiring no action, while advertising is a special communication form with intent to cause certain action from readers. For example, click here, click there, order this, buy that. : : There is no such intention, form, or terms on my info page. Just neutral information. I don't hide and I am not ashamed that I am write and author, and that is a part of the usual bio, including works. I checked your user page: "I graduated from the Czech University of Life Sciences in Prague and studied information science at the Faculty of Arts of Charles University." I think that if you had written a book on Life Science, you would have mentioned that as well. : : Most of the Info page is about my research and AIPA Method which is a valid contribution to psychology, consciousness studies, identity theory, and personality development. Actually, my paper '''AIPA Method: A Cognitive-Phenomenological Model for Identity Reconstruction and Stabilization in Pure Awareness''' is now in the peer review procedure at Journal of Consciousness Studies. : : Here is a part from the Wikiversity AIPA Method page in creation (waiting for the end of the time limit for new users): : == Introduction == : The AIPA Method addresses a gap in contemporary personal development and consciousness science: most evidence‑based approaches (CBT, MBSR, MBCT, standard meditation) operate at the level of mental content—reframing thoughts, observing them, or reducing their impact—rather than at the level of identity structure. In contrast, AIPA targets the structural relationship between the self and the mind, aiming at durable identity reconstruction rooted in Pure Awareness rather than symptom management. : : The central research question of the primary AIPA preprint is whether a structured, sequentially staged method can produce permanent identity reconstruction rooted in Pure Awareness, and how such a method compares to established approaches in scope, mechanism, and outcome. : : == Theoretical foundations == : The AIPA framework is grounded in the cognitive‑phenomenological tradition (e.g., McAdams, Varela, Metzinger, Erikson), contemporary consciousness science on minimal phenomenal experience, and qualitative methods advocacy in psychology. It builds directly on: :* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. :* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. :* Narrative identity and partial‑self models within personality and identity theory. : Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. : : == Experiential empiricism == : The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: :* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. :* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). :* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. :* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. : : All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. : : I believe this is a valid contribution to Wikiversity. : : Best regards, Senad [[User:Senad Dizdarević|Senad Dizdarević]] I suggest you check the deleted user page, and see for yourself if it is "spam" and "authority hack", or a legit author's page with one paragraph short presentation, while the rest of the page is about my research project.

I proposed to quasi-delete, i.e. '''move to userspace''' of the main (or sole?) creator, {{User|KYPark}}. The page is organized a little bit like a dictionary. It makes it redundant to Wiktionary except that Wikiversity allows original research and there does seem to be original research there. Thus, its being organized as a dictionary would alone not necessarily be a problem. Where I see a problem is in the organization and execution/implementation. Consider [[Korean/Words/가다]], which seems rather typical of the subpages (some subpages are like categories and transclude the pages for individual words): * On the putative definition line, there is this: "한곳에서 다른 곳으로 장소를 이동하다", apparently(?) in Korean. That does not seem to fit well into the ''English'' Wikiversity. * There seems to be some original research into etymological relations between Korean and European languages in the "Comparatives" section (from what I recall, the English Wiktionary rejected this kind of content from KYPark). Admittedly, it is marked using "This is a primary, secondary and/or original Eurasiatic research project at Wikiversity", so it could be tolerable, but even so, one has to wonder whether Wikiversity wants this kind of fringe science/research or outright pseudo-science. ** Fringe science: fringe physics has been moved to user space before. This would be fringe etymology. But then, original research is allowed. Deletion is not required; moving to user space suffices, I think. Alternatively, one could at least rename the pages to make it clear from the title that this is not Wikiversity voice but rather KYPark voice, e.g. "Korean/Words (KYPark)/..." or "Korean/Words/KYPark/..." (recall the "Fedosin" pages featuring the name "Fedosin"). Methodology: I see almost no methodological notes spanning the words at [[Korean/Words]]. And yet, if this is original research inventing new etymological connections, surely there should be some general considerations/analysis on how to proceed and how that manner of procedure differs from mainstream etymology?

I am not sure about how to proceed, although I am inclined to move it out of mainspace = quasi-delete. I am looking forward to get input from others, especially curators and custodians. Some considerations: 1) There is perhaps no more appearance/suspicion of copyright violation, now that the ResearchGate (RG) article (of which this is a copy, perhaps an incomplete copy?) carries a license. 2) The article is not a complete replica from RG: at a minimum, it lacks images. The inserter could have continued editing the page in his user space before he uploads images, that is, before he finalizes the page for consumption, but that did not happen. I did not check whether the text is an exact one-to-one match; the article does not indicate anything in that regard. 3) The principle implied seems to be this: users should feel free to duplicate non-peer-reviewed articles from RG in English Wikiversity, perhaps to increase the Google search and LLM yield. I find this problematic, in part for the duplication. I would say: choose a venue and publish it there. If RG is not good enough for you as a publishing venue, choose Wikiversity instead, but not both? 4) There are some features that appear unduly promotional. There is a link to a dot com home page of the inserter of the article. I dot not know how we handle or should handle this, whether prohibit such a link, etc. This is perhaps not so much a call to quasi-deletion but a call to make it less promotional. 5) I cannot determine the value of such an article. It seems to be a pseudo-article describing someone's browser extension. Can someone do a better analysis? --[[User:Dan Polansky|Dan Polansky]] ([[User talk:Dan Polansky|discuss]] • [[Special:Contributions/Dan Polansky|contribs]]) 06:48, 8 October 2025 (UTC) :2) Images for Wikicommons are being created, it will take a lot of time. and the text is not an exact one-to-one match :3) I also mentioned that It was being created so that it is more accessible from mobile phone, which is not possible in RG or in Zenodo :Let me clarify the purpose of uploading it to different platforms :Zenodo - registration and to link DOI :RG - Self Archiving :Wikiversity - Accessible by anyone from any device.

The Zotero Program is just one of many scientific literature management programs, that should be used for these purposes. Of course one can live without such a database but it helps a lot and can save a lot of time that could be used for more interesting issues. Not only that, but it helps to create better publications and knowledge. Without this program it can be very time consuming to publish a scientific article with the requested style for the references. Further in daily practice when you want to collect and cite a few references for a specific evidence in a clinical colloquium and discussion, this program is excellent. Therefore we strongly recommend that all maritime health persons learn how to use this excellent tool in their daily maritime health practice of all different types. There are good online courses for self-instruction on how to use Zotero. For example this one: Zotero fast online course But in order to increase IMHAR´s collective scientific strength in the use of EBM we would like to give training sessions in every possible opportunity, IMHA Symposia, seminars and other types of meetings. The database is useful for personal purposes but especially also for collaborative aims. At the IMHAR meeting in Paris Oct 7th 2016 we will give an introduction to the program by showing how it can be used in the daily practice and discuss strength and weaknesses compared to other similar databases." : Even longer is e.g. [[IMHA Research Archives/Scientific litterature search, storage and use/Medicina Maritima - the Spanish scientific maritime health journal]]. : However, that does not mean these should be salvaged. --[[User:Dan Polansky|Dan Polansky]] ([[User talk:Dan Polansky|discuss]] • [[Special:Contributions/Dan Polansky|contribs]]) 07:53, 21 November 2025 (UTC) == [[Palliative medicine]] == Underdeveloped and has not been improved on since 2007.

First, I asked him for help with "time limit for new users", and he replied - I should admit I dont know, what is "new user limit", but if filter blocks your page because of certain external link, you may force to save anyway and sometimes it works. It should not work, when the website is blacklisted. As of now, I am not seeing you to save page in main namespace, so try to save it without external links first. Then he wrote me another message: Well, I have analyzed your contribution to Wikiversity and I should point out here, that this project is not a place for advertising, so there is no way of promoting your books and authority this way. - probably referring to the intro of my About me page where I present me and my work. Before I could explain him the difference between the neutral information and advertising and promotion, he deleted my user page. Here is my answer I posted to the discussion today: : Hi, my About Me page is just an info page with the neutral as possible presentation of my work. : : There is a big difference between informing and advertising. Informing is neutrally stating that something exists and requiring no action, while advertising is a special communication form with intent to cause certain action from readers. For example, click here, click there, order this, buy that. : : There is no such intention, form, or terms on my info page. Just neutral information. I don't hide and I am not ashamed that I am write and author, and that is a part of the usual bio, including works. I checked your user page: "I graduated from the Czech University of Life Sciences in Prague and studied information science at the Faculty of Arts of Charles University." I think that if you had written a book on Life Science, you would have mentioned that as well. : : Most of the Info page is about my research and AIPA Method which is a valid contribution to psychology, consciousness studies, identity theory, and personality development. Actually, my paper '''AIPA Method: A Cognitive-Phenomenological Model for Identity Reconstruction and Stabilization in Pure Awareness''' is now in the peer review procedure at Journal of Consciousness Studies. : : Here is a part from the Wikiversity AIPA Method page in creation (waiting for the end of the time limit for new users): : == Introduction == : The AIPA Method addresses a gap in contemporary personal development and consciousness science: most evidence‑based approaches (CBT, MBSR, MBCT, standard meditation) operate at the level of mental content—reframing thoughts, observing them, or reducing their impact—rather than at the level of identity structure. In contrast, AIPA targets the structural relationship between the self and the mind, aiming at durable identity reconstruction rooted in Pure Awareness rather than symptom management. : : The central research question of the primary AIPA preprint is whether a structured, sequentially staged method can produce permanent identity reconstruction rooted in Pure Awareness, and how such a method compares to established approaches in scope, mechanism, and outcome. : : == Theoretical foundations == : The AIPA framework is grounded in the cognitive‑phenomenological tradition (e.g., McAdams, Varela, Metzinger, Erikson), contemporary consciousness science on minimal phenomenal experience, and qualitative methods advocacy in psychology. It builds directly on: :* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. :* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. :* Narrative identity and partial‑self models within personality and identity theory. : Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. : : == Experiential empiricism == : The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: :* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. :* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). :* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. :* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. : : All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. : : I believe this is a valid contribution to Wikiversity. : : Best regards, Senad [[User:Senad Dizdarević|Senad Dizdarević]] I suggest you check the deleted user page, and see for yourself if it is "spam" and "authority hack", or a legit author's page with one paragraph short presentation, while the rest of the page is about my research project.

I proposed to quasi-delete, i.e. '''move to userspace''' of the main (or sole?) creator, {{User|KYPark}}. The page is organized a little bit like a dictionary. It makes it redundant to Wiktionary except that Wikiversity allows original research and there does seem to be original research there. Thus, its being organized as a dictionary would alone not necessarily be a problem. Where I see a problem is in the organization and execution/implementation. Consider [[Korean/Words/가다]], which seems rather typical of the subpages (some subpages are like categories and transclude the pages for individual words): * On the putative definition line, there is this: "한곳에서 다른 곳으로 장소를 이동하다", apparently(?) in Korean. That does not seem to fit well into the ''English'' Wikiversity. * There seems to be some original research into etymological relations between Korean and European languages in the "Comparatives" section (from what I recall, the English Wiktionary rejected this kind of content from KYPark). Admittedly, it is marked using "This is a primary, secondary and/or original Eurasiatic research project at Wikiversity", so it could be tolerable, but even so, one has to wonder whether Wikiversity wants this kind of fringe science/research or outright pseudo-science. ** Fringe science: fringe physics has been moved to user space before. This would be fringe etymology. But then, original research is allowed. Deletion is not required; moving to user space suffices, I think. Alternatively, one could at least rename the pages to make it clear from the title that this is not Wikiversity voice but rather KYPark voice, e.g. "Korean/Words (KYPark)/..." or "Korean/Words/KYPark/..." (recall the "Fedosin" pages featuring the name "Fedosin"). Methodology: I see almost no methodological notes spanning the words at [[Korean/Words]]. And yet, if this is original research inventing new etymological connections, surely there should be some general considerations/analysis on how to proceed and how that manner of procedure differs from mainstream etymology?

I am not sure about how to proceed, although I am inclined to move it out of mainspace = quasi-delete. I am looking forward to get input from others, especially curators and custodians. Some considerations: 1) There is perhaps no more appearance/suspicion of copyright violation, now that the ResearchGate (RG) article (of which this is a copy, perhaps an incomplete copy?) carries a license. 2) The article is not a complete replica from RG: at a minimum, it lacks images. The inserter could have continued editing the page in his user space before he uploads images, that is, before he finalizes the page for consumption, but that did not happen. I did not check whether the text is an exact one-to-one match; the article does not indicate anything in that regard. 3) The principle implied seems to be this: users should feel free to duplicate non-peer-reviewed articles from RG in English Wikiversity, perhaps to increase the Google search and LLM yield. I find this problematic, in part for the duplication. I would say: choose a venue and publish it there. If RG is not good enough for you as a publishing venue, choose Wikiversity instead, but not both? 4) There are some features that appear unduly promotional. There is a link to a dot com home page of the inserter of the article. I dot not know how we handle or should handle this, whether prohibit such a link, etc. This is perhaps not so much a call to quasi-deletion but a call to make it less promotional. 5) I cannot determine the value of such an article. It seems to be a pseudo-article describing someone's browser extension. Can someone do a better analysis? --[[User:Dan Polansky|Dan Polansky]] ([[User talk:Dan Polansky|discuss]] • [[Special:Contributions/Dan Polansky|contribs]]) 06:48, 8 October 2025 (UTC) :2) Images for Wikicommons are being created, it will take a lot of time. and the text is not an exact one-to-one match :3) I also mentioned that It was being created so that it is more accessible from mobile phone, which is not possible in RG or in Zenodo :Let me clarify the purpose of uploading it to different platforms :Zenodo - registration and to link DOI :RG - Self Archiving :Wikiversity - Accessible by anyone from any device.

Further in daily practice when you want to collect and cite a few references for a specific evidence in a clinical colloquium and discussion, this program is excellent. Therefore we strongly recommend that all maritime health persons learn how to use this excellent tool in their daily maritime health practice of all different types. There are good online courses for self-instruction on how to use Zotero. For example this one: Zotero fast online course But in order to increase IMHAR´s collective scientific strength in the use of EBM we would like to give training sessions in every possible opportunity, IMHA Symposia, seminars and other types of meetings. The database is useful for personal purposes but especially also for collaborative aims. At the IMHAR meeting in Paris Oct 7th 2016 we will give an introduction to the program by showing how it can be used in the daily practice and discuss strength and weaknesses compared to other similar databases." : Even longer is e.g. [[IMHA Research Archives/Scientific litterature search, storage and use/Medicina Maritima - the Spanish scientific maritime health journal]]. : However, that does not mean these should be salvaged. --[[User:Dan Polansky|Dan Polansky]] ([[User talk:Dan Polansky|discuss]] • [[Special:Contributions/Dan Polansky|contribs]]) 07:53, 21 November 2025 (UTC) == [[Palliative medicine]] == {{archive top|'''Kept'''.

First, I asked him for help with "time limit for new users", and he replied - I should admit I dont know, what is "new user limit", but if filter blocks your page because of certain external link, you may force to save anyway and sometimes it works. It should not work, when the website is blacklisted. As of now, I am not seeing you to save page in main namespace, so try to save it without external links first. Then he wrote me another message: Well, I have analyzed your contribution to Wikiversity and I should point out here, that this project is not a place for advertising, so there is no way of promoting your books and authority this way. - probably referring to the intro of my About me page where I present me and my work. Before I could explain him the difference between the neutral information and advertising and promotion, he deleted my user page. Here is my answer I posted to the discussion today: : Hi, my About Me page is just an info page with the neutral as possible presentation of my work. : : There is a big difference between informing and advertising. Informing is neutrally stating that something exists and requiring no action, while advertising is a special communication form with intent to cause certain action from readers. For example, click here, click there, order this, buy that. : : There is no such intention, form, or terms on my info page. Just neutral information. I don't hide and I am not ashamed that I am write and author, and that is a part of the usual bio, including works. I checked your user page: "I graduated from the Czech University of Life Sciences in Prague and studied information science at the Faculty of Arts of Charles University." I think that if you had written a book on Life Science, you would have mentioned that as well. : : Most of the Info page is about my research and AIPA Method which is a valid contribution to psychology, consciousness studies, identity theory, and personality development. Actually, my paper '''AIPA Method: A Cognitive-Phenomenological Model for Identity Reconstruction and Stabilization in Pure Awareness''' is now in the peer review procedure at Journal of Consciousness Studies. : : Here is a part from the Wikiversity AIPA Method page in creation (waiting for the end of the time limit for new users): : == Introduction == : The AIPA Method addresses a gap in contemporary personal development and consciousness science: most evidence‑based approaches (CBT, MBSR, MBCT, standard meditation) operate at the level of mental content—reframing thoughts, observing them, or reducing their impact—rather than at the level of identity structure. In contrast, AIPA targets the structural relationship between the self and the mind, aiming at durable identity reconstruction rooted in Pure Awareness rather than symptom management. : : The central research question of the primary AIPA preprint is whether a structured, sequentially staged method can produce permanent identity reconstruction rooted in Pure Awareness, and how such a method compares to established approaches in scope, mechanism, and outcome. : : == Theoretical foundations == : The AIPA framework is grounded in the cognitive‑phenomenological tradition (e.g., McAdams, Varela, Metzinger, Erikson), contemporary consciousness science on minimal phenomenal experience, and qualitative methods advocacy in psychology. It builds directly on: :* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. :* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. :* Narrative identity and partial‑self models within personality and identity theory. : Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. : : == Experiential empiricism == : The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: :* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. :* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). :* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. :* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. : : All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. : : I believe this is a valid contribution to Wikiversity. : : Best regards, Senad [[User:Senad Dizdarević|Senad Dizdarević]] I suggest you check the deleted user page, and see for yourself if it is "spam" and "authority hack", or a legit author's page with one paragraph short presentation, while the rest of the page is about my research project.

The sources ''themselves'' don't even back up the claims. It's just used as proof for an established concept, where the user then uses this established concept to jump to an unsupported, laughable conclusion that is pulled out of thin air. It's utterly ridiculous to even consider such a page for mainspace since it clearly violates our [[Wikiversity:Verifiability]] policy.

It mentions a ''chance'' of "life there [a habitable exoplanet] might not be limited to microbes, but could include creatures as large and varied as the megalosauruses or microraptors that once roamed Earth.", but again, no justification to take this article as proof that "aliens may have visited us!". There's no mention of aliens visiting Earth anywhere in the article.

It makes it redundant to Wiktionary except that Wikiversity allows original research and there does seem to be original research there. Thus, its being organized as a dictionary would alone not necessarily be a problem. Where I see a problem is in the organization and execution/implementation. Consider [[Korean/Words/가다]], which seems rather typical of the subpages (some subpages are like categories and transclude the pages for individual words): * On the putative definition line, there is this: "한곳에서 다른 곳으로 장소를 이동하다", apparently(?) in Korean. That does not seem to fit well into the ''English'' Wikiversity. * There seems to be some original research into etymological relations between Korean and European languages in the "Comparatives" section (from what I recall, the English Wiktionary rejected this kind of content from KYPark). Admittedly, it is marked using "This is a primary, secondary and/or original Eurasiatic research project at Wikiversity", so it could be tolerable, but even so, one has to wonder whether Wikiversity wants this kind of fringe science/research or outright pseudo-science. ** Fringe science: fringe physics has been moved to user space before. This would be fringe etymology. But then, original research is allowed. Deletion is not required; moving to user space suffices, I think. Alternatively, one could at least rename the pages to make it clear from the title that this is not Wikiversity voice but rather KYPark voice, e.g. "Korean/Words (KYPark)/..." or "Korean/Words/KYPark/..." (recall the "Fedosin" pages featuring the name "Fedosin"). Methodology: I see almost no methodological notes spanning the words at [[Korean/Words]]. And yet, if this is original research inventing new etymological connections, surely there should be some general considerations/analysis on how to proceed and how that manner of procedure differs from mainstream etymology?

I am not sure about how to proceed, although I am inclined to move it out of mainspace = quasi-delete. I am looking forward to get input from others, especially curators and custodians. Some considerations: 1) There is perhaps no more appearance/suspicion of copyright violation, now that the ResearchGate (RG) article (of which this is a copy, perhaps an incomplete copy?) carries a license. 2) The article is not a complete replica from RG: at a minimum, it lacks images. The inserter could have continued editing the page in his user space before he uploads images, that is, before he finalizes the page for consumption, but that did not happen. I did not check whether the text is an exact one-to-one match; the article does not indicate anything in that regard. 3) The principle implied seems to be this: users should feel free to duplicate non-peer-reviewed articles from RG in English Wikiversity, perhaps to increase the Google search and LLM yield. I find this problematic, in part for the duplication. I would say: choose a venue and publish it there. If RG is not good enough for you as a publishing venue, choose Wikiversity instead, but not both? 4) There are some features that appear unduly promotional. There is a link to a dot com home page of the inserter of the article. I dot not know how we handle or should handle this, whether prohibit such a link, etc. This is perhaps not so much a call to quasi-deletion but a call to make it less promotional. 5) I cannot determine the value of such an article. It seems to be a pseudo-article describing someone's browser extension. Can someone do a better analysis? --[[User:Dan Polansky|Dan Polansky]] ([[User talk:Dan Polansky|discuss]] • [[Special:Contributions/Dan Polansky|contribs]]) 06:48, 8 October 2025 (UTC) :2) Images for Wikicommons are being created, it will take a lot of time. and the text is not an exact one-to-one match :3) I also mentioned that It was being created so that it is more accessible from mobile phone, which is not possible in RG or in Zenodo :Let me clarify the purpose of uploading it to different platforms :Zenodo - registration and to link DOI :RG - Self Archiving :Wikiversity - Accessible by anyone from any device.

First, I asked him for help with "time limit for new users", and he replied - I should admit I dont know, what is "new user limit", but if filter blocks your page because of certain external link, you may force to save anyway and sometimes it works. It should not work, when the website is blacklisted. As of now, I am not seeing you to save page in main namespace, so try to save it without external links first. Then he wrote me another message: Well, I have analyzed your contribution to Wikiversity and I should point out here, that this project is not a place for advertising, so there is no way of promoting your books and authority this way. - probably referring to the intro of my About me page where I present me and my work. Before I could explain him the difference between the neutral information and advertising and promotion, he deleted my user page. Here is my answer I posted to the discussion today: : Hi, my About Me page is just an info page with the neutral as possible presentation of my work. : : There is a big difference between informing and advertising. Informing is neutrally stating that something exists and requiring no action, while advertising is a special communication form with intent to cause certain action from readers. For example, click here, click there, order this, buy that. : : There is no such intention, form, or terms on my info page. Just neutral information. I don't hide and I am not ashamed that I am write and author, and that is a part of the usual bio, including works. I checked your user page: "I graduated from the Czech University of Life Sciences in Prague and studied information science at the Faculty of Arts of Charles University." I think that if you had written a book on Life Science, you would have mentioned that as well. : : Most of the Info page is about my research and AIPA Method which is a valid contribution to psychology, consciousness studies, identity theory, and personality development. Actually, my paper '''AIPA Method: A Cognitive-Phenomenological Model for Identity Reconstruction and Stabilization in Pure Awareness''' is now in the peer review procedure at Journal of Consciousness Studies. : : Here is a part from the Wikiversity AIPA Method page in creation (waiting for the end of the time limit for new users): : == Introduction == : The AIPA Method addresses a gap in contemporary personal development and consciousness science: most evidence‑based approaches (CBT, MBSR, MBCT, standard meditation) operate at the level of mental content—reframing thoughts, observing them, or reducing their impact—rather than at the level of identity structure. In contrast, AIPA targets the structural relationship between the self and the mind, aiming at durable identity reconstruction rooted in Pure Awareness rather than symptom management. : : The central research question of the primary AIPA preprint is whether a structured, sequentially staged method can produce permanent identity reconstruction rooted in Pure Awareness, and how such a method compares to established approaches in scope, mechanism, and outcome. : : == Theoretical foundations == : The AIPA framework is grounded in the cognitive‑phenomenological tradition (e.g., McAdams, Varela, Metzinger, Erikson), contemporary consciousness science on minimal phenomenal experience, and qualitative methods advocacy in psychology. It builds directly on: :* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. :* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. :* Narrative identity and partial‑self models within personality and identity theory. : Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. : : == Experiential empiricism == : The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: :* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. :* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). :* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. :* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. : : All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. : : I believe this is a valid contribution to Wikiversity. : : Best regards, Senad [[User:Senad Dizdarević|Senad Dizdarević]] I suggest you check the deleted user page, and see for yourself if it is "spam" and "authority hack", or a legit author's page with one paragraph short presentation, while the rest of the page is about my research project.

The sources ''themselves'' don't even back up the claims. It's just used as proof for an established concept, where the user then uses this established concept to jump to an unsupported, laughable conclusion that is pulled out of thin air. It's utterly ridiculous to even consider such a page for mainspace since it clearly violates our [[Wikiversity:Verifiability]] policy.

It mentions a ''chance'' of "life there [a habitable exoplanet] might not be limited to microbes, but could include creatures as large and varied as the megalosauruses or microraptors that once roamed Earth.", but again, no justification to take this article as proof that "aliens may have visited us!". There's no mention of aliens visiting Earth anywhere in the article.

The point being is that these arguments are not supported by the sources. Even the article you mention poses the idea as a hypothetical model. This is just you twisting the article to fit your unsupported narrative. I'll bring direct quotes for you to show why the linked article does not help you: :::* ''One problem the researchers do make sure to point out is that '''they are working with only one data point: our own behaviors and capabilities for space exploration'''. “We tried to come up with a model that would involve the fewest assumptions about sociology that we could,” Carroll-Nellenback told Business Insider.

I proposed to quasi-delete, i.e. '''move to userspace''' of the main (or sole?) creator, {{User|KYPark}}. The page is organized a little bit like a dictionary. It makes it redundant to Wiktionary except that Wikiversity allows original research and there does seem to be original research there. Thus, its being organized as a dictionary would alone not necessarily be a problem. Where I see a problem is in the organization and execution/implementation. Consider [[Korean/Words/가다]], which seems rather typical of the subpages (some subpages are like categories and transclude the pages for individual words): * On the putative definition line, there is this: "한곳에서 다른 곳으로 장소를 이동하다", apparently(?) in Korean. That does not seem to fit well into the ''English'' Wikiversity. * There seems to be some original research into etymological relations between Korean and European languages in the "Comparatives" section (from what I recall, the English Wiktionary rejected this kind of content from KYPark). Admittedly, it is marked using "This is a primary, secondary and/or original Eurasiatic research project at Wikiversity", so it could be tolerable, but even so, one has to wonder whether Wikiversity wants this kind of fringe science/research or outright pseudo-science. ** Fringe science: fringe physics has been moved to user space before. This would be fringe etymology. But then, original research is allowed. Deletion is not required; moving to user space suffices, I think. Alternatively, one could at least rename the pages to make it clear from the title that this is not Wikiversity voice but rather KYPark voice, e.g. "Korean/Words (KYPark)/..." or "Korean/Words/KYPark/..." (recall the "Fedosin" pages featuring the name "Fedosin"). Methodology: I see almost no methodological notes spanning the words at [[Korean/Words]]. And yet, if this is original research inventing new etymological connections, surely there should be some general considerations/analysis on how to proceed and how that manner of procedure differs from mainstream etymology?

I am not sure about how to proceed, although I am inclined to move it out of mainspace = quasi-delete. I am looking forward to get input from others, especially curators and custodians. Some considerations: 1) There is perhaps no more appearance/suspicion of copyright violation, now that the ResearchGate (RG) article (of which this is a copy, perhaps an incomplete copy?) carries a license. 2) The article is not a complete replica from RG: at a minimum, it lacks images. The inserter could have continued editing the page in his user space before he uploads images, that is, before he finalizes the page for consumption, but that did not happen. I did not check whether the text is an exact one-to-one match; the article does not indicate anything in that regard. 3) The principle implied seems to be this: users should feel free to duplicate non-peer-reviewed articles from RG in English Wikiversity, perhaps to increase the Google search and LLM yield. I find this problematic, in part for the duplication. I would say: choose a venue and publish it there. If RG is not good enough for you as a publishing venue, choose Wikiversity instead, but not both? 4) There are some features that appear unduly promotional. There is a link to a dot com home page of the inserter of the article.

Therefore we strongly recommend that all maritime health persons learn how to use this excellent tool in their daily maritime health practice of all different types. There are good online courses for self-instruction on how to use Zotero.

First, I asked him for help with "time limit for new users", and he replied - I should admit I dont know, what is "new user limit", but if filter blocks your page because of certain external link, you may force to save anyway and sometimes it works. It should not work, when the website is blacklisted. As of now, I am not seeing you to save page in main namespace, so try to save it without external links first. Then he wrote me another message: Well, I have analyzed your contribution to Wikiversity and I should point out here, that this project is not a place for advertising, so there is no way of promoting your books and authority this way. - probably referring to the intro of my About me page where I present me and my work. Before I could explain him the difference between the neutral information and advertising and promotion, he deleted my user page. Here is my answer I posted to the discussion today: : Hi, my About Me page is just an info page with the neutral as possible presentation of my work. : : There is a big difference between informing and advertising. Informing is neutrally stating that something exists and requiring no action, while advertising is a special communication form with intent to cause certain action from readers. For example, click here, click there, order this, buy that. : : There is no such intention, form, or terms on my info page. Just neutral information. I don't hide and I am not ashamed that I am write and author, and that is a part of the usual bio, including works. I checked your user page: "I graduated from the Czech University of Life Sciences in Prague and studied information science at the Faculty of Arts of Charles University." I think that if you had written a book on Life Science, you would have mentioned that as well. : : Most of the Info page is about my research and AIPA Method which is a valid contribution to psychology, consciousness studies, identity theory, and personality development. Actually, my paper '''AIPA Method: A Cognitive-Phenomenological Model for Identity Reconstruction and Stabilization in Pure Awareness''' is now in the peer review procedure at Journal of Consciousness Studies. : : Here is a part from the Wikiversity AIPA Method page in creation (waiting for the end of the time limit for new users): : == Introduction == : The AIPA Method addresses a gap in contemporary personal development and consciousness science: most evidence‑based approaches (CBT, MBSR, MBCT, standard meditation) operate at the level of mental content—reframing thoughts, observing them, or reducing their impact—rather than at the level of identity structure. In contrast, AIPA targets the structural relationship between the self and the mind, aiming at durable identity reconstruction rooted in Pure Awareness rather than symptom management. : : The central research question of the primary AIPA preprint is whether a structured, sequentially staged method can produce permanent identity reconstruction rooted in Pure Awareness, and how such a method compares to established approaches in scope, mechanism, and outcome. : : == Theoretical foundations == : The AIPA framework is grounded in the cognitive‑phenomenological tradition (e.g., McAdams, Varela, Metzinger, Erikson), contemporary consciousness science on minimal phenomenal experience, and qualitative methods advocacy in psychology. It builds directly on: :* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. :* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. :* Narrative identity and partial‑self models within personality and identity theory. : Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. : : == Experiential empiricism == : The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: :* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. :* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). :* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. :* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. : : All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. : : I believe this is a valid contribution to Wikiversity. : : Best regards, Senad [[User:Senad Dizdarević|Senad Dizdarević]] I suggest you check the deleted user page, and see for yourself if it is "spam" and "authority hack", or a legit author's page with one paragraph short presentation, while the rest of the page is about my research project.

The sources ''themselves'' don't even back up the claims. It's just used as proof for an established concept, where the user then uses this established concept to jump to an unsupported, laughable conclusion that is pulled out of thin air. It's utterly ridiculous to even consider such a page for mainspace since it clearly violates our [[Wikiversity:Verifiability]] policy. This is, once again, pseudoscientific content that has caused our website to reduce in quality over the last few years. :* Going source by source, we can see that: :#[https://web.archive.org/web/20250918011642/https://timesofindia.indiatimes.com/blogs/thebigd/compress-earths-history-into-24-hrs-humans-came-at-1158-pm-yet-killed-70-of-wildlife/ ‘Compress Earth’s history into 24 hrs.

It just talks about Earth's history in accordance with the 24-hour metric of time, and the author tries to use this article as a 'piece in the puzzle' of aliens "possibly" visiting Earth... which, once again, is unsupported and is not backed up anywhere in the article. :#[https://web.archive.org/web/20250808053249/https://news.cornell.edu/stories/2023/11/jurassic-worlds-might-be-easier-spot-modern-earth The Cornell article does not even remotely support the idea that "aliens visited Earth"]. It mentions a ''chance'' of "life there [a habitable exoplanet] might not be limited to microbes, but could include creatures as large and varied as the megalosauruses or microraptors that once roamed Earth.", but again, no justification to take this article as proof that "aliens may have visited us!". There's no mention of aliens visiting Earth anywhere in the article. Once again this is only proving the background premise, but not the unsupported, nonsensical "alien likelihood" argument that the author of this garbage page is trying to push so desperately. :#The Parker Solar Probe WP article does not even mention aliens either.

Instead of insulting others' intelligence, maybe engage with the actual reasoning rather than censoring it away. And there are lots of sources, such as [https://interestingengineering.com/science/alien-civilizations-may-have-visited-earth-millions-of-years-ago-study-says Alien Civilizations May Have Visited Earth Millions of Years Ago, Study Says] etc etc. The sources are used for the arguments themselves individually.

The point being is that these arguments are not supported by the sources. Even the article you mention poses the idea as a hypothetical model. This is just you twisting the article to fit your unsupported narrative. I'll bring direct quotes for you to show why the linked article does not help you: :::* ''One problem the researchers do make sure to point out is that '''they are working with only one data point: our own behaviors and capabilities for space exploration'''. “We tried to come up with a model that would involve the fewest assumptions about sociology that we could,” Carroll-Nellenback told Business Insider. '''We have no real way of knowing the motivations of an alien civilization'''.'' --> proves that this is just speculation and no evidence-based arguments have been provided for the idea that aliens likely visited Earth. :::And I'm not sure if you read my entire response, but I ''did'' engage with your "actual reasoning" and exposed its weaknesses and lack of adherence to Wikiversity policies.

This perception is not necessarily borne out during the exchange as there are many clues to a persons background and status to be found in their spelling, their choice of individual words, their grammar and their prosaic style. Fortunately, there are some online tools that are readily available to help level the communication playing field.

Personally I recognize that English is not homogeneous in its usage across the world. It is also not homogeneous in America nor in my region of the southwestern portion of the country and not in my state of California and not in my city of San Diego. None the less, I can discern things in my own communication which may give anyone communicating with me a clue as to who and where I am just by my use of this common tongue.Because I use a relatively refined vocabulary and write with a fair amount of clarity, someone communicating with me would find it easy to assume that I am well educated. If my communication is of a formal business nature they may have a hard time gaining more insight into anything more about me including my nationality, my race, and even my gender. If I am using a user name online it can hide or reveal things about me depending on how I craft it. I am comfortable in my communication abilities and I also feel that I am a fair judge of other people's communication skill. In addition to common speech forms I also have some knowledge of several specialized vocabularies. My background in general science and biology allow me to understand and exchange information in these subject areas that would be less comprehensible to others who have little background in these areas. I also have some background with several foreign languages but I do not have enough mastery over them to feel comfortable on my own with any extensive communications with anyone who is fluent in those languages. Stereo Type Threat Concerns: A stereotype threat is faced by someone when anything they do or say makes someone else and perhaps even themselves be likely to characterize them as being a typical example of the stereotype.When the stereotype is a negative one, it can be self threatening enough that it can be disruptive to the efforts of the effected person just by the existence of this threat alone. African American students have historically labored under this condition. "Whenever they perform an explicitly scholastic or intellectual task, they face the threat of confirming being judged by a negative societal stereotype- a suspicion- about their race's intellectual ability and competence." (Stereotype Threat and the Intellectual Test Performance of African Americans, Steele & Aronson 1995). In regards to online communications, this threat can have a dampening effect upon the participation of African Americans and other potential groups who would be negatively stereotyped. Even though written communications via e-mail or instant text messages should carry some anonymity, the threat could stop their participation before they even begin. Hopefully if they know that there resources available in real time for them to use while communicating online, they will be less likely to fall prey to the stereotype threat. The Usefulness of Embedded Dictionaries and Web Page Dictionary Resources To be honest, my spelling is atrocious (ha ha I actually spelled that right the first time by some miracle). I tend to be phonetic when I attempt to write out the words I am thinking about. I am quite grateful for embedded dictionaries in most text programs that are on the computer and in email and other online communication programs. I also have an online dictionary bookmarked and in those times when I am using a simple text program without an embedded dictionary or those times when I need to hand write something, my browser is usually opened to the online dictionary for quick reference. My dictionary of choice for this is: http://www.merriam-webster.com They have a nice search bar that works with those of us who can get close to the spelling but not hit the mark and they have an alphabetized listing for those who are further from getting the right spelling. The Usefulness of Web Based Thesauruses So after you have the spelling of the word you want to use and you successfully use it in your communications, you may find that you are worried about being redundant. A good thing repeated the same way can be too much of a good thing. This is where the online thesaurus comes in handy. For example, if I am talking about a boat, I don't want to sink my link by using that appellation over and over, so I click on the tab I have open to: http://thesaurus.reference.com. I type in boat in their search bar and here is what I get; '''"Main Entry: boat''' '''Part of Speech: noun''' '''Definition: vehicle for water travel''' '''Synonyms:''' ''' ark, barge, bark, bateau, bottom, bucket, canoe, catamaran, craft, dinghy, dory, gondola, hulk, ketch, launch, lifeboat, pinnace, raft, sailboat, schooner, scow, ship, skiff, sloop, steamboat, tub, yacht''' '''Notes: a boat is a vessel that can be hauled aboard a ship, according to the Navy, with a ship being somewhat larger."''' This information gives me lots of ways to call a boat by any other name, though it will not necessarily be as sweet. It keeps you afloat on the sea of communication and not foundering on the rocks of redundancy. Using The Open Source Dictionary and Wordnick This is all well and good if someone is just needing to communicate one way. But when an online exchange is more instantaneous, you may need an additional resource or two at your disposal. Fortunately you can have multiple tabs and full browser pages open on most modern computers. If someone you were communicating with was to throw the term "carbolicious" at you, you might have nary a clue as to it's meaning and your online dictionary may not have it either. there are several places though where this term may be found. One is: http://www3.merriam-webster.com/opendictionary They have alphabetized listings and a search bar as well so just type in the term in the search bar and you have improved your chances of knowing what the other person is talking about. Another good site for this type of communication impediment is: http://www.wordnik.com They also have listings of unusual words and phrases. If neither the traditional resources or these alternate resources have this information the I suggest calling out your online communication partner by asking did you just make that up or something? Using Specialized Scientific Vocabulary I advise caution when you encounter the need to use specialized vocabulary or encounter it being used by someone else. Scientific vocabulary can be especially tricky. Terms such as carrying capacity have nothing to do with weight in the scientific discipline of Ecology. The term is used when describing what amount of a certain type of living organism a particular ecosystem can sustain. It would be difficult to anticipate all the potentials for miscommunication with specialized vocabularies and just smarter to admit that you do not know everything instead. Using Google Translator Venturing you online communications into the realm of internationalism can be daunting. Not only do you not share a language with many of the people across the world, you also may lack an understanding of their cultural norms. The way to go when you encounter someone from a foreign country online who does not speak your language is to proceed cautiously and respectfully. It is not generally too hard to establish names and country affiliations but after that you may be at a loss as to how to proceed. If the other person speaks and writes in one of a few of the most common languages, I suggest using: http://translate.google.com This is not a perfect translator so expect that there may be snags to your communication, but overall it is a good way to have conversations longer than the equivalent of "Me Tarzan, You Jane". Places for Teachers to use These Communication Tools I have found several teacher's resource web sites that have chat enabled that could be a good place to try out theese tools. they are: http://teachers.net/mentors and: http://www.theteacherscorner.net/forums Good luck with the chatting and be careful of those specialized vocabularies and foreign tongues.

This perception is not necessarily borne out during the exchange as there are many clues to a persons background and status to be found in their spelling, their choice of individual words, their grammar and their prosaic style. Fortunately, there are some online tools that are readily available to help level the communication playing field.

Personally I recognize that English is not homogeneous in its usage across the world. It is also not homogeneous in America nor in my region of the southwestern portion of the country and not in my state of California and not in my city of San Diego. None the less, I can discern things in my own communication which may give anyone communicating with me a clue as to who and where I am just by my use of this common tongue.Because I use a relatively refined vocabulary and write with a fair amount of clarity, someone communicating with me would find it easy to assume that I am well educated. If my communication is of a formal business nature they may have a hard time gaining more insight into anything more about me including my nationality, my race, and even my gender. If I am using a user name online it can hide or reveal things about me depending on how I craft it. I am comfortable in my communication abilities and I also feel that I am a fair judge of other people's communication skill. In addition to common speech forms I also have some knowledge of several specialized vocabularies. My background in general science and biology allow me to understand and exchange information in these subject areas that would be less comprehensible to others who have little background in these areas. I also have some background with several foreign languages but I do not have enough mastery over them to feel comfortable on my own with any extensive communications with anyone who is fluent in those languages. Stereo Type Threat Concerns: A stereotype threat is faced by someone when anything they do or say makes someone else and perhaps even themselves be likely to characterize them as being a typical example of the stereotype.When the stereotype is a negative one, it can be self threatening enough that it can be disruptive to the efforts of the effected person just by the existence of this threat alone. African American students have historically labored under this condition. "Whenever they perform an explicitly scholastic or intellectual task, they face the threat of confirming being judged by a negative societal stereotype- a suspicion- about their race's intellectual ability and competence." (Stereotype Threat and the Intellectual Test Performance of African Americans, Steele & Aronson 1995). In regards to online communications, this threat can have a dampening effect upon the participation of African Americans and other potential groups who would be negatively stereotyped. Even though written communications via e-mail or instant text messages should carry some anonymity, the threat could stop their participation before they even begin. Hopefully if they know that there resources available in real time for them to use while communicating online, they will be less likely to fall prey to the stereotype threat. The Usefulness of Embedded Dictionaries and Web Page Dictionary Resources To be honest, my spelling is atrocious (ha ha I actually spelled that right the first time by some miracle). I tend to be phonetic when I attempt to write out the words I am thinking about. I am quite grateful for embedded dictionaries in most text programs that are on the computer and in email and other online communication programs. I also have an online dictionary bookmarked and in those times when I am using a simple text program without an embedded dictionary or those times when I need to hand write something, my browser is usually opened to the online dictionary for quick reference. My dictionary of choice for this is: http://www.merriam-webster.com They have a nice search bar that works with those of us who can get close to the spelling but not hit the mark and they have an alphabetized listing for those who are further from getting the right spelling. The Usefulness of Web Based Thesauruses So after you have the spelling of the word you want to use and you successfully use it in your communications, you may find that you are worried about being redundant. A good thing repeated the same way can be too much of a good thing. This is where the online thesaurus comes in handy. For example, if I am talking about a boat, I don't want to sink my link by using that appellation over and over, so I click on the tab I have open to: http://thesaurus.reference.com. I type in boat in their search bar and here is what I get; '''"Main Entry: boat''' '''Part of Speech: noun''' '''Definition: vehicle for water travel''' '''Synonyms:''' ''' ark, barge, bark, bateau, bottom, bucket, canoe, catamaran, craft, dinghy, dory, gondola, hulk, ketch, launch, lifeboat, pinnace, raft, sailboat, schooner, scow, ship, skiff, sloop, steamboat, tub, yacht''' '''Notes: a boat is a vessel that can be hauled aboard a ship, according to the Navy, with a ship being somewhat larger."''' This information gives me lots of ways to call a boat by any other name, though it will not necessarily be as sweet. It keeps you afloat on the sea of communication and not foundering on the rocks of redundancy. Using The Open Source Dictionary and Wordnick This is all well and good if someone is just needing to communicate one way. But when an online exchange is more instantaneous, you may need an additional resource or two at your disposal. Fortunately you can have multiple tabs and full browser pages open on most modern computers. If someone you were communicating with was to throw the term "carbolicious" at you, you might have nary a clue as to it's meaning and your online dictionary may not have it either. there are several places though where this term may be found. One is: http://www3.merriam-webster.com/opendictionary They have alphabetized listings and a search bar as well so just type in the term in the search bar and you have improved your chances of knowing what the other person is talking about. Another good site for this type of communication impediment is: http://www.wordnik.com They also have listings of unusual words and phrases. If neither the traditional resources or these alternate resources have this information the I suggest calling out your online communication partner by asking did you just make that up or something? Using Specialized Scientific Vocabulary I advise caution when you encounter the need to use specialized vocabulary or encounter it being used by someone else. Scientific vocabulary can be especially tricky. Terms such as carrying capacity have nothing to do with weight in the scientific discipline of Ecology. The term is used when describing what amount of a certain type of living organism a particular ecosystem can sustain. It would be difficult to anticipate all the potentials for miscommunication with specialized vocabularies and just smarter to admit that you do not know everything instead. Using Google Translator Venturing you online communications into the realm of internationalism can be daunting. Not only do you not share a language with many of the people across the world, you also may lack an understanding of their cultural norms. The way to go when you encounter someone from a foreign country online who does not speak your language is to proceed cautiously and respectfully. It is not generally too hard to establish names and country affiliations but after that you may be at a loss as to how to proceed. If the other person speaks and writes in one of a few of the most common languages, I suggest using: http://translate.google.com This is not a perfect translator so expect that there may be snags to your communication, but overall it is a good way to have conversations longer than the equivalent of "Me Tarzan, You Jane". Places for Teachers to use These Communication Tools I have found several teacher's resource web sites that have chat enabled that could be a good place to try out theese tools. they are: http://teachers.net/mentors and: http://www.theteacherscorner.net/forums Good luck with the chatting and be careful of those specialized vocabularies and foreign tongues.

Steele & Joshua Aronson "The Language of Science, The Language of Students" Heldref Publications 2005 by: Edyth Young == Department of Physical Constraints == izpgylwakvrqt8q2xf1i2dauulwvatm Wikiversity:Review board 4 4010 2809908 2127026 2026-05-17T11:19:22Z Jtneill 10242 /* See also */ 2809908 wikitext text/x-wiki {{Administering Wikiversity}} '''Note''': This page contains some suggestions for the review board system detailed at [[betawikiversity:Wikiversity:Review_board/En|beta]]. ---- The role of "experts" as Wikipedia editors has always been controversial. Often, the people who know the most about a topic are advised not to edit articles about that topic because of the danger of introducing personal biases. Well-documented and objectively-verifiable facts are given preference over expert opinion. While Wikiversity encourages the recognition of biases, Wikiversity also wants to encourage the participation of experienced educators who will share their expertise within the Wikiversity community. In order to facilitate the constructive utilization of expert knowledge that exists within the Wikiversity community, Wikiversity can develop a new type of wiki functionary, the "referee". Wikiversity referees can be particularly useful in several roles: #trusted advisors for students #trusted editors for guiding the community towards satisfactory outcomes of content disputes #facilitators of a formal [[Wikiversity:Peer review|peer review]] process for [[Wikiversity:Original research|original research]] #liaisons for facilitating interactions between Wikiversity and professional educators and researchers outside of Wikiversity ==Trust== In order for Wikiversity to function efficiently as a meeting place for learners and experienced teachers, it is important that Wikiversity have a system that will allow participants to know something about the backgrounds of people they interact with at Wikiversity. As "[[w:Category:Wikipedia functionaries|functionaries]]" with special responsibilities, Wikiversity referees need to be subjected to a special level of scrutiny in order to generate and sustain trust within the Wikiversity community. Wikiversity referees need to have a public record of constructive activity within Wikiversity. This public record depends on the record of page edits that exists in the "history" of each wiki page. If a Wikiversity participant makes useful edits and has constructive interactions with other members of the community, their edit history will reflect their service to the community. However, it is cumbersome to review the edit history of a wiki editor. Wikiversity needs a systematic way to convert edit histories into evaluations of potential referees. How does a wiki deal with this sort of problem? Wikipedia has developed a special subset of wiki editors: [[w:Wikipedia:Administrators|administrators]]. A Wikipedia administrator is a "trusted member of the community" who has undergone an explicit [[w:Wikipedia:Requests for adminship|peer-review]] by the community. Administrators are experienced wiki editors and are expected to have knowledge of the community policies that regulate [[w:Administrators' reading list|how the wiki works]]. Wikiversity, like all WikiMedia projects, needs administrators (here we call them "[[Wikiversity:Custodianship|custodians]]"). However, when it comes to questions about article content, custodians are no different from any other Wikiversity editor. Being a custodian/administrator for a wiki indicates a certain amount of expertise about that wiki, but says nothing about expertise in any other area. ==Peer review of referees== In addition to custodians/administrators, Wikipedia has other "[[w:Category:Wikipedia functionaries|functionaries]]" who perform special tasks (for Wikiversity functionaries, see [[Wikiversity:Support staff|Support staff]]). A Wikiversity referee is a member of the community who makes a special commitment to share their education-related expertise with the Wikiversity community. The special commitment includes submitting to a peer-review process by which the community openly documents the past history of the referee in such a way that it becomes relatively easy for all members of the community to know if the referee has expertise in particular subject areas that are of interest to the Wikiversity community. As for other Wikiversity functionaries, being a Wikiversity referee is not an "honor", it is a commitment to perform special tasks for the community. In particular, Wikiversity referees will be called upon for help with those tasks that require expert knowledge about a subject area within Wikiversity. ==Expert opinion about wiki content== Wikipedia has always had to deal with simple vandalism and more sophisticated "jokes" and falsifications. Persistent problems are met by blocking users from editing and protecting pages from being edited. Sometimes "spoof" articles are added to Wikipedia that pass the casual inspection of vandalism patrollers. It takes an expert to spot a good spoof. Wikiversity needs experts in all topic areas who can provide informed opinion when there are disputes or uncertainty about Wikiversity content. Wikiversity referees have the <b>special obligation</b> of recognizing spoofs and frauds <b>and explaining to non-experts how to understand that specific Wikiversity content is bogus</b>. ==Ambassadorial function== Wikiversity is devoted to exploration of how to use the wiki user interface to promote learning. While exploring new ways of learning, Wikiversity seeks to have constructive relations with the "outside world" of more conventional educational institutions. Wikiversity tries to provide educational resources to the world and also provides a platform by which educators and researchers from all around the world can interact. Many working professionals cannot commit their time to projects unless they trust the people they are working with. Wikiversity does not use a standard system of academic credentials, so outside professionals face a problem in knowing if they can have a professional interaction with members of the Wikiversity community. The process by which Wikiversity openly evaluates the performance of Wikiversity referees provides a system for designating trusted members of the Wikiversity community with expert knowledge in certain topic areas. Wikiversity referees can function as ambassadorial contacts for outside professionals seeking to build collaborative projects with Wikiversity. ==Peer review of original research== Conducting [[Wikiversity:Original research|original research]] is not the main [[Wikiversity:Mission|mission]] of Wikiversity, but unlike the long-standing policy of Wikipedia, original research is not excluded from Wikiversity. Any original research that arises within Wikiversity must be clearly identified as such and subjected to formal peer review. The Wikiversity peer review process must be entirely transparent and openly conducted in wiki format. Wikiversity referees can act to facilitate and guide the Wikiversity community as it reviews original research results within Wikiversity. ==See also== *[[User:JWSchmidt/Wikiversity/Review board]] - A copy of the ([http://beta.wikiversity.org/wiki/Wikiversity:Research_guidelines/En original at the beta-wikiversity hub]) *[[Wikiversity:Research ethics]] *[[Wikiversity:Research process]] *[[WikiJournal User Group]] - Peer reviewed wiki publishing *[http://en.wikipedia.org/w/index.php?title=Wikipedia:Wikipedia_Signpost/2006-07-31/Listserv&oldid=66968788 Professors criticize, praise Wikipedia in listserv discussions] [[Category:Pages moved from Meta]] [[Category:Research policy proposals]] [[Category:Wikiversity ethics]] [[Category:Research ethics]] [[de:Wikiversity:Review Board]] efsbc0ap7j760iqpkrtl6hxwsyq9hba Ruby 0 5858 2809847 2344328 2026-05-17T04:00:58Z HenriPittier 3076895 2809847 wikitext text/x-wiki __NOTOC__ {{delete}} <small>This is a placeholder for [[Portal:Engineering and Technology]] --> [[School:Computer Science]] --> [[Topic:Computer Programming]] --> Ruby</small> {{RoundBoxTop|theme=2}} ==Introduction== [[w:Ruby_(programming_language)|Ruby]] is a free, pure object-oriented, and interpreted programming language.

Original research can generate unverifiable data and conclusions. It is also possible for nonresearch-related ideas and writings to masquerade as research. As outlined at [[Wikiversity:Research guidelines|Research guidelines]], acceptable original research at Wikiversity is shaped by ethical considerations and precautions against research methods that lead to inaccurate or falsified data. Wikiversity relies on peer review of research projects to identify and correct problems that might arise in research projects. In addition to conventional wiki peer review by wiki webpage editing, Wikiversity also seeks to establish a more formalized system for peer review; the Research Review Board ("Review Board", for short). The Review Board is a group of community-approved Wikiversity participants tasked to help the community verify the methods used in research projects and deal with any potential problems. ==Pre-approval of research projects== Most types of Wikiversity research projects do not need to be submitted to the Review Board for approval before they are started as Wikiversity webpages. A possible exception is any research activity conducted at Wikiversity that would normally require review by an [[w:Institutional review board|Institutional Review Board]]. Potentially, a research project approved by an IRB at a bricks-and-mortar research institution could involve research activities conducted at Wikiversity. Any such IRB-approved research should be evaluated by the Wikiversity Review Board in order to make sure that the proposed research does not violate Wikimedia Foundation policy and is not beyond the educational mission of Wikiversity. ==Review of research methods and practice== The main function of the Review Board is to help guide the whole Wikiversity community in peer review of research projects. It is of particular concern that each research project adhere to the [[Wikiversity:Research guidelines|Wikiversity research guidelines]]. The Review Board helps the community distinguish between valid research methods and bogus research methods. When problems in research methods and practices are identified, the Review Board helps the community respond so as to correct any problems in research activities at Wikiversity. In conjunction with Wikiversity sysops, problematical research projects that cannot be corrected will be terminated. In keeping with the educational mission of Wikiversity, the Review Board will help Wikiversity participants learn how to use productive and reliable research methods. ==Wiki publishing== Wikiversity does not have a system for formal peer review of research results and conclusions. The Review Board does not "approve" the results from original research projects before they are considered "published" on Wikiversity. All members of Wikiversity research projects can post their research conclusions on wiki webpages, but such "informal publication" does not imply any certification of the research by the Review Board or Wikiversity. The Review Board only helps the community make sure that research projects are conducted according to Wikiversity research guidelines and sound research methods. A long-term goal is for Wikiversity to explore the possibility of having a formal peer review system for research reports. It is possible that in the future the Review Board could evolve into a way for experts to conduct formal peer review of research results within Wikiversity. Until then, any research results arising from research projects at Wikiversity should be submitted for peer review at conventional journals. ==Referees== The Review Board members are called "Referees". Referees are Wikiversity participants nominated then accepted by the community in a similar manner to how [[Wikiversity:Custodianship|Custodians]] are selected. Referees help the community: *mark pages of original research projects with the appropriate template *make sure that original research follows the [[Wikiversity:Research guidelines|Research Guidelines]] *approve any research-related activities at Wikiversity that are part another institution's IRB-approval research project *make sure data and research results arising from original research are correctly archived and not manipulated after posting as an historical archive *identify and correct poor research methods or work with sysops to terminate projects that cannot be corrected Referees are not Custodians - they do not have the privileges to deal with breaches in the guidelines beyond editing the wiki webpages of research projects. If a research project needs to be terminated, referees can request that Custodians take action to delete pages or block editors who refuse to follow the research guidelines. However, some Referees may also be Custodians. In such cases, the account holder of such privileges needs to clearly identify the role they are acting in so that there is no actual or perceived conflict of interest. ==Selection of referees== Referees are selected because of their past history of Wikiversity editing. Wikiversity editors who have demonstrated expertise in particular subject areas and an interest in helping the community monitor the methods and practices of research projects will be potential candidate Referees. Candidates can self-nominate or be nominated by someone else. Candidates become Referees following community discussion and approval by consensus. Such candidates must demonstrate a sufficient level of competence in order to referee. ==Conduct of referees== Becoming a Referee means taking on extra duties and responsibilities in service of the Wikiversity community. In particular, Referees are expected to apply their expertise and experience to help guide the community in peer review of research methods and practices used in Wikiversity research projects. Referees never demand action based on their "expert opinion", rather they use their expertise to help provide explanations that guide the community to consensus. ==See also== *Research policies **[[Wikiversity:Research guidelines|Research Guidelines]] for Wikiversity **[[Wikiversity:Scope of research|Scope of Research]] for Wikiversity *Research-related pages **[[Wikiversity:Research]] - Source documents concerning research within Wikiversity **[[betawikiversity:Wikiversity:Original research/En|Original Research]] - unpublished research into a topic using literature review and/or methods in addition to literature review **[[betawikiversity:Wikiversity:Secondary research/En|Secondary research]] - research into a topic using the method of literature review rwvjugjmu72urece2vx9ilqlk5dglkc 2809906 2809905 2026-05-17T11:17:53Z Jtneill 10242 {{Notice|See also [[Wikiversity:Review board]]}} 2809906 wikitext text/x-wiki {{Notice|See also [[Wikiversity:Review board]]}} {{Research policy}} [[betawikiversity:Wikiversity:Original research/En|Original Research]] projects at Wikiversity introduce a risk that unsound methods will be used in some projects.

Would it be desirable to have such a thing? How would it working for the company? Ideas and comments are very welcome. ==Is it desirable?== Even if we don't have an aggregated or centralised page for blog ''posts'', I think it is a good idea to list individual ''blogs'' from a centralised page. For example, my own blog can never be picked up via a category, as it is on a external host. [[User:Cormaggio|Cormaggio]] <sup><small>[[User talk:Cormaggio|talk]]</small></sup> 10:02, 30 July 2008 (UTC) : The RSS reader extension is now enabled on the sandbox server, so a proof-of-concept could be created. Maybe we can use Google Reader for now to burn a single feed of all related WV blogs. But I suspect we're not going to be seeing such an extension enabled on WM projects for some time.

However, blogs can be updated as frequently as necessary, so there is no constraint on regular publishing. --[[User:HappyCamper|HappyCamper]] 11:49, 30 July 2008 (UTC) ==How would it work?== Would it be best as an aggregation of all posts to all blogs? Would it simply be a free-form editable page that people can post to directly? Would it be an aggregator for shorter ' micro-blogging' updates, such as Twitter or Facebook 'status'? Just some ideas to get the ball rolling... [[User:Cormaggio|Cormaggio]] <sup><small>[[User talk:Cormaggio|talk]]</small></sup> 10:02, 30 July 2008 (UTC) : For it to fly here, now, I'd vote for "a free-form editable page that people can post to directly".

This might give the front page some sense of there being a community of learners and practitioners here - which is not so obviously apparent from our front page... [[User:Cormaggio|Cormaggio]] <sup><small>[[User talk:Cormaggio|talk]]</small></sup> 10:02, 30 July 2008 (UTC) : Maybe a summary of each blog post for inclusion; and the main blog post would be not included?

Ideas and comments are very welcome. ==Is it desirable?== Even if we don't have an aggregated or centralised page for blog ''posts'', I think it is a good idea to list individual ''blogs'' from a centralised page.

This course is meant to introduce new students to the study of diplomatic history by explaining the concept of diplomacy, terms that the student will use often in the [[Topic:Diplomatic History|Department of Diplomatic History]], and a broad history of international relations on a global scale. This is the first course students new to the department should complete as it will be the foundation for successive courses. Courses within the Department of Diplomatic History will be primarily self-study, placing the educational responsibility on the student rather than the professor. Although the professor will provide a plan for study and general information, it is the responsibility of the student to fulfil the goals and expectations of the course by completing the readings, studying the provided lesson, and performing independent research to prove comprehension. This course is also designed for homeschooling use, with information for the homeschool instructor to aid the student in successful completion. Recommendations for further study will be provided with each homeschooling lesson to expand upon the basic course. ==Denelder Homeschooling Series on History== As denoted by the infobox above, this course is a lesson created by [[User:Dr_Denelder|Dr. Jason Denelder]] as a part of his lesson series for homeschooled students. This lesson was designed as an aid for homeschoolers to further their knowledge on a specific topic, not to replace regular homeschooling lesson plans and resources. The Introduction to Diplomatic History is intended as the first lesson in the Department of Diplomatic History and is classified as HS-DH001 in the Homeschooling Series. ==Suggested Readings== *[http://www.diplom.org/Zine/S1995R/Szykman/History.html Diplomacy: An Historical Perspective] Simon Szykman. Spring 1995. Carnegie Mellon University. *[http://www.ediplomat.com/nd/history.htm A Brief History of Diplomacy] eDiplomat. *[http://diplo.diplomacy.edu/books/mdiplomacy_book/langhorne/langhorne.htm History and the Evolution of Diplomacy] Richard Langhorne. *[http://diplo.diplomacy.edu/books/mdiplomacy_book/petrovski/petrovski.htm Diplomacy as an Instrument of Good Governance] Vladimir Petrovsky. ==Course Syllabus== ===Goals and Expectations=== That students will understand the concept of diplomacy in a historical sense, will understand the basic terms of diplomatic research, and will gain an understanding of international relations on a global scale throughout history. That students will be able to implement their newly gained knowledge and successfully demonstrate their understanding by developing a researched essay on a general topic of diplomatic history. ===Reading Schedule=== ===Essay=== The purpose of the essay is to demonstrate an understanding of the basics of diplomacy in the context of diplomatic history. As this is considered a university first-year course, grammar, spelling, and rhetoric should be correct and consistent throughout. Substance, however, is the most important component of a successful essay, demonstrating comprehension of the idea of diplomacy and its practical uses. Students have open control over the topic of their choice as long as it relates to the course material. Essays should be at least two pages long, although this should not be looked upon as a maximum. As the purpose is to demonstrate comprehension, the student should not write a descriptive essay, but rather an analytical essay. This means that the student should analyze a topic in diplomatic history, discussing the consequences of such an action and possible alternate paths and their consequences, using terms and concepts from the lesson. Since this is an introductory course that encompasses the entire history of international relations, possible topics are endless in scope. In the essay, it is better to narrow in on a particular incident rather than discuss a broad topic. Do not analyze the diplomacy of Europe during the First World War, rather, analyze the effects of the War Guilt Clause on relations between Germany and the United Kingdom. Be specific in your analysis. For those students wishing for constructive criticism of their essays may email them to Dr. Denelder at jason.denelder@yahoo.com. He will read your essay, making comments and noting corrections where necessary. If submitting the essay, please allow up to two weeks to accommodate Dr. Denelder's busy schedule. ===Course Completion=== Successful completion of DIPL 1001 is dependent on the student's understanding of the concept of diplomacy and the broad history of international relations demonstrated by the satisfactory completion of an essay on a selected topic of diplomatic history. DIPL 1001 serves as the prerequisite course for continuation into more detailed courses of diplomatic history and should be completed first. ==Lesson Plan/Outline== ===Synopsis=== ===Concepts=== ===Terms=== *'''Diplomacy:''' the art and practice of conducting negotiations between representatives of groups or states; also, the employment of tact to gain strategic advantage or to find mutually acceptable solutions to a common challenge *'''International Diplomacy:''' the conduct of international relations through the intercession of professional diplomats with regard to issues of peace-making, trade, war, economics, and culture *'''Diplomatic Immunity:''' a form of legal immunity and a policy held between governments, which ensures that diplomats are given safe passage and are considered not susceptible to lawsuit or prosecution under the host country's laws *'''Diplomatic Recognition:''' a unilateral political act, with domestic and international legal consequences, whereby a state acknowledges an act or status of another state or government *'''Paradiplomacy:''' the international relations conducted by subnational, regional, local or non-central governments ===Important Figures=== ===Timeline=== ==Course Roster== *--[[User:Jolie|Jolie]] 22:22, 9 October 2008 (UTC) ==Professorship== * [[User:Dr_Denelder|Dr. Jason Denelder]] - For questions, concerns, discussion, or comment, please use my [[User talk:Dr_Denelder|talk page]] or email me at jason.denelder@yahoo.com.

The information was about a computer programmer who committed suicide in front of one of Bank of America's properties. According to the the article, he was despondent after losing his job at Bofa, which went to H1B workers. Flanagn and his layed off coleauges all of whom lost their jobs were tasked with training their replacements. ::To make a long story short, there were two persistent editors guarding information on the Bofa article, and I eventually moved on to other areas. Those two kept the story out of wikipedia, and months or even years later I found out that the article about Flanagan himself disappreaed as well.

Without getting into the specifics of any editing disputes from the past or possible criminal disappearances, etc. it seems like your main question is, "Are there ''really'' a shortage of COBOL specialists?" and the answer is 100% yes. This has been a known problem for well over a decade (likely longer) and if you want evidence of that, I would recommend looking at job listings to see how much a company will pay someone with COBOL knowledge versus (e.g.) Python or C+.

These images, such as [[:File:Redfield equation (non-Markovian).png]] and [[:File:Lindblad equation (Markovian).png]], don't even match the text he puts them with.

In contrast, AIPA targets the structural relationship between the self and the mind, aiming at durable identity reconstruction rooted in Pure Awareness rather than symptom management. ::::::The central research question of the primary AIPA preprint is whether a structured, sequentially staged method can produce permanent identity reconstruction rooted in Pure Awareness, and how such a method compares to established approaches in scope, mechanism, and outcome. :::::: == Theoretical foundations == ::::::The AIPA framework is grounded in the cognitive‑phenomenological tradition (e.g., McAdams, Varela, Metzinger, Erikson), contemporary consciousness science on minimal phenomenal experience, and qualitative methods advocacy in psychology. It builds directly on: ::::::* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. ::::::* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. ::::::* Narrative identity and partial‑self models within personality and identity theory. ::::::Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. :::::: == Experiential empiricism == ::::::The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: ::::::* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. ::::::* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). ::::::* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. ::::::* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. ::::::All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. ::::::I believe this is a valid contribution to Wikiversity. ::::::Best regards, ::::::Senad [[User:Senad Dizdarević|Senad Dizdarević]] ([[User talk:Senad Dizdarević|discuss]] • [[Special:Contributions/Senad Dizdarević|contribs]]) 06:54, 2 April 2026 (UTC) == Unable to publish pages == Whenever I try to publish a page with linked sources it gets flagged and says I'm a new user attempting to publish content with outside links.

Quoting from the reference: <blockquote> There are enormous benefits of applying AI-based solutions to monitor workers’ health and prevent accidents or, currently, COVID-19 infections, and those benefits are reported with enormous potential. According to the recent Deloitte and MedTech Europe report [11], implementing AI in European healthcare systems could save up 380,000 to 403,000 lives annually or €170.9 to 212.4 billion per year. </blockquote> Not that the reference says ''could save'', not ''saves'' as in the essay.

In contrast, AIPA targets the structural relationship between the self and the mind, aiming at durable identity reconstruction rooted in Pure Awareness rather than symptom management. ::::::The central research question of the primary AIPA preprint is whether a structured, sequentially staged method can produce permanent identity reconstruction rooted in Pure Awareness, and how such a method compares to established approaches in scope, mechanism, and outcome. :::::: == Theoretical foundations == ::::::The AIPA framework is grounded in the cognitive‑phenomenological tradition (e.g., McAdams, Varela, Metzinger, Erikson), contemporary consciousness science on minimal phenomenal experience, and qualitative methods advocacy in psychology. It builds directly on: ::::::* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. ::::::* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. ::::::* Narrative identity and partial‑self models within personality and identity theory. ::::::Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. :::::: == Experiential empiricism == ::::::The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: ::::::* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. ::::::* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). ::::::* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. ::::::* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. ::::::All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. ::::::I believe this is a valid contribution to Wikiversity. ::::::Best regards, ::::::Senad [[User:Senad Dizdarević|Senad Dizdarević]] ([[User talk:Senad Dizdarević|discuss]] • [[Special:Contributions/Senad Dizdarević|contribs]]) 06:54, 2 April 2026 (UTC) == Unable to publish pages == Whenever I try to publish a page with linked sources it gets flagged and says I'm a new user attempting to publish content with outside links.

Myself and students use some AI-generated images in the [[Motivation and emotion]] project. [[User:Dronebogus]] has been removing some of these images from Wikiversity pages and nominating them for deletion at Commons. As a result, some have been deleted and some have been kept. Dronebogus has made some useful edits and image suggestions for [[Motivation and emotion]] which I've appreciated and incorporated. However, there are other edits to remove an AI image by Dronebogus that I've reverted where I think the image is more educational than no image or an alternative image suggested by Dronebogus. There are a couple of pages where Dronebogus has reverted my reversion, so we are at risk of edit warring. We have briefly discussed and warned each other on our user talk pages, but it seems to come down to a difference in perception about the educational usefulness of the AI images. So, I'm asking here for others to please review the recent edit histories for these pages: * [[Motivation and emotion/Lectures/Brain and physiological needs]] * [[Motivation and emotion/Book/2025/Stockholm syndrome emotion]] and let us know what you think about the AI image suitability vs. using no image or alternative images suggested by Dronebogus.

In contrast, AIPA targets the structural relationship between the self and the mind, aiming at durable identity reconstruction rooted in Pure Awareness rather than symptom management. ::::::The central research question of the primary AIPA preprint is whether a structured, sequentially staged method can produce permanent identity reconstruction rooted in Pure Awareness, and how such a method compares to established approaches in scope, mechanism, and outcome. :::::: == Theoretical foundations == ::::::The AIPA framework is grounded in the cognitive‑phenomenological tradition (e.g., McAdams, Varela, Metzinger, Erikson), contemporary consciousness science on minimal phenomenal experience, and qualitative methods advocacy in psychology. It builds directly on: ::::::* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. ::::::* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. ::::::* Narrative identity and partial‑self models within personality and identity theory. ::::::Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. :::::: == Experiential empiricism == ::::::The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: ::::::* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. ::::::* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). ::::::* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. ::::::* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. ::::::All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. ::::::I believe this is a valid contribution to Wikiversity. ::::::Best regards, ::::::Senad [[User:Senad Dizdarević|Senad Dizdarević]] ([[User talk:Senad Dizdarević|discuss]] • [[Special:Contributions/Senad Dizdarević|contribs]]) 06:54, 2 April 2026 (UTC) == Unable to publish pages == Whenever I try to publish a page with linked sources it gets flagged and says I'm a new user attempting to publish content with outside links.

Take for rexample the sentence: <blockquote> Due to its efficiency, AI has saved 380,000-403,000 lives per year in European healthcare as reported in a recent Deloitte and MedTech Europe report<ref>Dantas, C., Mackiewicz, K., Tageo, V., Jacucci, G., Guardado, D., Ortet, S., Varlamis, I., Maniadakis, M., De Lera, E., Quintas, J., Kocsis, O., & Vassiliou, C.

Quoting from the reference: <blockquote> There are enormous benefits of applying AI-based solutions to monitor workers’ health and prevent accidents or, currently, COVID-19 infections, and those benefits are reported with enormous potential. According to the recent Deloitte and MedTech Europe report [11], implementing AI in European healthcare systems could save up 380,000 to 403,000 lives annually or €170.9 to 212.4 billion per year. </blockquote> Not that the reference says ''could save'', not ''saves'' as in the essay.

In contrast, AIPA targets the structural relationship between the self and the mind, aiming at durable identity reconstruction rooted in Pure Awareness rather than symptom management. ::::::The central research question of the primary AIPA preprint is whether a structured, sequentially staged method can produce permanent identity reconstruction rooted in Pure Awareness, and how such a method compares to established approaches in scope, mechanism, and outcome. :::::: == Theoretical foundations == ::::::The AIPA framework is grounded in the cognitive‑phenomenological tradition (e.g., McAdams, Varela, Metzinger, Erikson), contemporary consciousness science on minimal phenomenal experience, and qualitative methods advocacy in psychology. It builds directly on: ::::::* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. ::::::* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. ::::::* Narrative identity and partial‑self models within personality and identity theory. ::::::Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. :::::: == Experiential empiricism == ::::::The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: ::::::* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. ::::::* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). ::::::* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. ::::::* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. ::::::All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. ::::::I believe this is a valid contribution to Wikiversity. ::::::Best regards, ::::::Senad [[User:Senad Dizdarević|Senad Dizdarević]] ([[User talk:Senad Dizdarević|discuss]] • [[Special:Contributions/Senad Dizdarević|contribs]]) 06:54, 2 April 2026 (UTC) == Unable to publish pages == Whenever I try to publish a page with linked sources it gets flagged and says I'm a new user attempting to publish content with outside links.

With the help of the internet and digital tools, students can now study, practice, and gain experience without being physically present in a classroom. One key part of this system is the online internship, which helps students learn real-world skills along with their studies. ::An online internship allows students to work on tasks and projects through digital platforms. This makes learning more practical and useful, especially for those who want to understand how real work environments function. ::'''Background''' ::The concept of online learning developed from distance education, where students learned from remote locations. Over time, with the growth of digital technology, learning has become more interactive and flexible. ::The introduction of the online internship has added another important layer to digital education. It combines theoretical learning with practical experience, helping students prepare for future careers. ::During global events such as the COVID-19 pandemic, online education and online internship programs became essential. They helped students continue learning and gaining experience despite restrictions on physical movement. ::'''Importance of Online Internship''' ::An online internship plays an important role in student development. It helps bridge the gap between academic knowledge and practical skills. ::'''Some key points include:''' ::Students understand how real work is done ::They develop basic professional skills ::It supports career readiness ::It allows learning without location limits ::By participating in an online internship, students can improve their confidence and gain early exposure to different fields. ::'''Features of Online Internship-Based Learning''' ::Modern education platforms often include online internship opportunities as part of their learning system. These usually offer: ::Flexible schedules for students ::Access to learning from home ::Beginner-friendly tasks and projects ::A combination of theory and practice ::Such features make online internship programs suitable for a wide range of learners, including beginners. ::'''Learning Tasks''' ::Explore how online internship programs support student learning in digital environments. ::Identify how students can gain practical experience through an online internship ::Analyze the role of flexible learning in improving student engagement ::Understand how online education and internships work together ::'''References''' ::[https://ijpsl.in/wp-content/uploads/2020/09/E-Learning_Hanaaya-Navaneeth.pdf The Past, Present and Future of E-Learning: Hanaaya Varyani and Navaneeth M S] ::[https://ieeexplore.ieee.org/document/9788102 Current Trends and Future Perspectives of e-Learning in India] ::'''See Also''' ::[https://easyshiksha.com/online_courses/internship Online Internship] ::[https://easyshiksha.com/online_courses/ Online Courses] ::[https://easyshiksha.com/online_courses/kids-learning Kids Learning] ::[https://easyshiksha.com/career_helper/ Career Guidance] [[User:EasyshikshaMarketing|EasyshikshaMarketing]] ([[User talk:EasyshikshaMarketing|discuss]] • [[Special:Contributions/EasyshikshaMarketing|contribs]]) 05:27, 17 April 2026 (UTC) :::@[[User:EasyshikshaMarketing|EasyshikshaMarketing]] Wikiversity is a resource for education, or a space for education.

Myself and students use some AI-generated images in the [[Motivation and emotion]] project. [[User:Dronebogus]] has been removing some of these images from Wikiversity pages and nominating them for deletion at Commons. As a result, some have been deleted and some have been kept. Dronebogus has made some useful edits and image suggestions for [[Motivation and emotion]] which I've appreciated and incorporated. However, there are other edits to remove an AI image by Dronebogus that I've reverted where I think the image is more educational than no image or an alternative image suggested by Dronebogus. There are a couple of pages where Dronebogus has reverted my reversion, so we are at risk of edit warring. We have briefly discussed and warned each other on our user talk pages, but it seems to come down to a difference in perception about the educational usefulness of the AI images. So, I'm asking here for others to please review the recent edit histories for these pages: * [[Motivation and emotion/Lectures/Brain and physiological needs]] * [[Motivation and emotion/Book/2025/Stockholm syndrome emotion]] and let us know what you think about the AI image suitability vs. using no image or alternative images suggested by Dronebogus.

In contrast, AIPA targets the structural relationship between the self and the mind, aiming at durable identity reconstruction rooted in Pure Awareness rather than symptom management. ::::::The central research question of the primary AIPA preprint is whether a structured, sequentially staged method can produce permanent identity reconstruction rooted in Pure Awareness, and how such a method compares to established approaches in scope, mechanism, and outcome. :::::: == Theoretical foundations == ::::::The AIPA framework is grounded in the cognitive‑phenomenological tradition (e.g., McAdams, Varela, Metzinger, Erikson), contemporary consciousness science on minimal phenomenal experience, and qualitative methods advocacy in psychology. It builds directly on: ::::::* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. ::::::* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. ::::::* Narrative identity and partial‑self models within personality and identity theory. ::::::Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. :::::: == Experiential empiricism == ::::::The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: ::::::* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. ::::::* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). ::::::* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. ::::::* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. ::::::All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. ::::::I believe this is a valid contribution to Wikiversity. ::::::Best regards, ::::::Senad [[User:Senad Dizdarević|Senad Dizdarević]] ([[User talk:Senad Dizdarević|discuss]] • [[Special:Contributions/Senad Dizdarević|contribs]]) 06:54, 2 April 2026 (UTC) == Unable to publish pages == Whenever I try to publish a page with linked sources it gets flagged and says I'm a new user attempting to publish content with outside links.

Myself and students use some AI-generated images in the [[Motivation and emotion]] project. [[User:Dronebogus]] has been removing some of these images from Wikiversity pages and nominating them for deletion at Commons. As a result, some have been deleted and some have been kept. Dronebogus has made some useful edits and image suggestions for [[Motivation and emotion]] which I've appreciated and incorporated. However, there are other edits to remove an AI image by Dronebogus that I've reverted where I think the image is more educational than no image or an alternative image suggested by Dronebogus. There are a couple of pages where Dronebogus has reverted my reversion, so we are at risk of edit warring. We have briefly discussed and warned each other on our user talk pages, but it seems to come down to a difference in perception about the educational usefulness of the AI images. So, I'm asking here for others to please review the recent edit histories for these pages: * [[Motivation and emotion/Lectures/Brain and physiological needs]] * [[Motivation and emotion/Book/2025/Stockholm syndrome emotion]] and let us know what you think about the AI image suitability vs. using no image or alternative images suggested by Dronebogus.

In contrast, AIPA targets the structural relationship between the self and the mind, aiming at durable identity reconstruction rooted in Pure Awareness rather than symptom management. ::::::The central research question of the primary AIPA preprint is whether a structured, sequentially staged method can produce permanent identity reconstruction rooted in Pure Awareness, and how such a method compares to established approaches in scope, mechanism, and outcome. :::::: == Theoretical foundations == ::::::The AIPA framework is grounded in the cognitive‑phenomenological tradition (e.g., McAdams, Varela, Metzinger, Erikson), contemporary consciousness science on minimal phenomenal experience, and qualitative methods advocacy in psychology. It builds directly on: ::::::* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. ::::::* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. ::::::* Narrative identity and partial‑self models within personality and identity theory. ::::::Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. :::::: == Experiential empiricism == ::::::The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: ::::::* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. ::::::* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). ::::::* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. ::::::* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. ::::::All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. ::::::I believe this is a valid contribution to Wikiversity. ::::::Best regards, ::::::Senad [[User:Senad Dizdarević|Senad Dizdarević]] ([[User talk:Senad Dizdarević|discuss]] • [[Special:Contributions/Senad Dizdarević|contribs]]) 06:54, 2 April 2026 (UTC) == Unable to publish pages == Whenever I try to publish a page with linked sources it gets flagged and says I'm a new user attempting to publish content with outside links.

Dronebogus has made some useful edits and image suggestions for [[Motivation and emotion]] which I've appreciated and incorporated.

So, I'm asking here for others to please review the recent edit histories for these pages: * [[Motivation and emotion/Lectures/Brain and physiological needs]] * [[Motivation and emotion/Book/2025/Stockholm syndrome emotion]] and let us know what you think about the AI image suitability vs. using no image or alternative images suggested by Dronebogus.

In contrast, AIPA targets the structural relationship between the self and the mind, aiming at durable identity reconstruction rooted in Pure Awareness rather than symptom management. ::::::The central research question of the primary AIPA preprint is whether a structured, sequentially staged method can produce permanent identity reconstruction rooted in Pure Awareness, and how such a method compares to established approaches in scope, mechanism, and outcome. :::::: == Theoretical foundations == ::::::The AIPA framework is grounded in the cognitive‑phenomenological tradition (e.g., McAdams, Varela, Metzinger, Erikson), contemporary consciousness science on minimal phenomenal experience, and qualitative methods advocacy in psychology. It builds directly on: ::::::* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. ::::::* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. ::::::* Narrative identity and partial‑self models within personality and identity theory. ::::::Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. :::::: == Experiential empiricism == ::::::The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: ::::::* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. ::::::* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). ::::::* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. ::::::* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. ::::::All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. ::::::I believe this is a valid contribution to Wikiversity. ::::::Best regards, ::::::Senad [[User:Senad Dizdarević|Senad Dizdarević]] ([[User talk:Senad Dizdarević|discuss]] • [[Special:Contributions/Senad Dizdarević|contribs]]) 06:54, 2 April 2026 (UTC) == Unable to publish pages == Whenever I try to publish a page with linked sources it gets flagged and says I'm a new user attempting to publish content with outside links.

In contrast, AIPA targets the structural relationship between the self and the mind, aiming at durable identity reconstruction rooted in Pure Awareness rather than symptom management. ::::::The central research question of the primary AIPA preprint is whether a structured, sequentially staged method can produce permanent identity reconstruction rooted in Pure Awareness, and how such a method compares to established approaches in scope, mechanism, and outcome. :::::: == Theoretical foundations == ::::::The AIPA framework is grounded in the cognitive‑phenomenological tradition (e.g., McAdams, Varela, Metzinger, Erikson), contemporary consciousness science on minimal phenomenal experience, and qualitative methods advocacy in psychology. It builds directly on: ::::::* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. ::::::* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. ::::::* Narrative identity and partial‑self models within personality and identity theory. ::::::Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. :::::: == Experiential empiricism == ::::::The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: ::::::* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. ::::::* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). ::::::* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. ::::::* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. ::::::All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. ::::::I believe this is a valid contribution to Wikiversity. ::::::Best regards, ::::::Senad [[User:Senad Dizdarević|Senad Dizdarević]] ([[User talk:Senad Dizdarević|discuss]] • [[Special:Contributions/Senad Dizdarević|contribs]]) 06:54, 2 April 2026 (UTC) == Unable to publish pages == Whenever I try to publish a page with linked sources it gets flagged and says I'm a new user attempting to publish content with outside links.

So, I'm asking here for others to please review the recent edit histories for these pages: * [[Motivation and emotion/Lectures/Brain and physiological needs]] * [[Motivation and emotion/Book/2025/Stockholm syndrome emotion]] and let us know what you think about the AI image suitability vs. using no image or alternative images suggested by Dronebogus. Sincerely, James -- [[User:Jtneill|Jtneill]] - <small>[[User talk:Jtneill|Talk]] - [[Special:Contributions/Jtneill|c]]</small> 11:45, 26 April 2026 (UTC) :I think Jtneill needs to try harder to find non-AI alternatives both on Commons and the web. I’m not reiterating the well known problems with generative AI— you can read about those on Wikipedia and the broader Internet. Needless to say it’s kind of just inherently toxic. If you use it, it should be the last resort of last resorts. Just my stance, which I consider perfectly valid and reasonable.

In contrast, AIPA targets the structural relationship between the self and the mind, aiming at durable identity reconstruction rooted in Pure Awareness rather than symptom management. ::::::The central research question of the primary AIPA preprint is whether a structured, sequentially staged method can produce permanent identity reconstruction rooted in Pure Awareness, and how such a method compares to established approaches in scope, mechanism, and outcome. :::::: == Theoretical foundations == ::::::The AIPA framework is grounded in the cognitive‑phenomenological tradition (e.g., McAdams, Varela, Metzinger, Erikson), contemporary consciousness science on minimal phenomenal experience, and qualitative methods advocacy in psychology. It builds directly on: ::::::* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. ::::::* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. ::::::* Narrative identity and partial‑self models within personality and identity theory. ::::::Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. :::::: == Experiential empiricism == ::::::The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: ::::::* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. ::::::* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). ::::::* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. ::::::* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. ::::::All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. ::::::I believe this is a valid contribution to Wikiversity. ::::::Best regards, ::::::Senad [[User:Senad Dizdarević|Senad Dizdarević]] ([[User talk:Senad Dizdarević|discuss]] • [[Special:Contributions/Senad Dizdarević|contribs]]) 06:54, 2 April 2026 (UTC) == Unable to publish pages == Whenever I try to publish a page with linked sources it gets flagged and says I'm a new user attempting to publish content with outside links.

Myself and students use some AI-generated images in the [[Motivation and emotion]] project. [[User:Dronebogus]] has been removing some of these images from Wikiversity pages and nominating them for deletion at Commons. As a result, some have been deleted and some have been kept. Dronebogus has made some useful edits and image suggestions for [[Motivation and emotion]] which I've appreciated and incorporated. However, there are other edits to remove an AI image by Dronebogus that I've reverted where I think the image is more educational than no image or an alternative image suggested by Dronebogus. There are a couple of pages where Dronebogus has reverted my reversion, so we are at risk of edit warring. We have briefly discussed and warned each other on our user talk pages, but it seems to come down to a difference in perception about the educational usefulness of the AI images. So, I'm asking here for others to please review the recent edit histories for these pages: * [[Motivation and emotion/Lectures/Brain and physiological needs]] * [[Motivation and emotion/Book/2025/Stockholm syndrome emotion]] and let us know what you think about the AI image suitability vs. using no image or alternative images suggested by Dronebogus.

If you use it, it should be the last resort of last resorts. Just my stance, which I consider perfectly valid and reasonable.

In contrast, AIPA targets the structural relationship between the self and the mind, aiming at durable identity reconstruction rooted in Pure Awareness rather than symptom management. ::::::The central research question of the primary AIPA preprint is whether a structured, sequentially staged method can produce permanent identity reconstruction rooted in Pure Awareness, and how such a method compares to established approaches in scope, mechanism, and outcome. :::::: == Theoretical foundations == ::::::The AIPA framework is grounded in the cognitive‑phenomenological tradition (e.g., McAdams, Varela, Metzinger, Erikson), contemporary consciousness science on minimal phenomenal experience, and qualitative methods advocacy in psychology. It builds directly on: ::::::* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. ::::::* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. ::::::* Narrative identity and partial‑self models within personality and identity theory. ::::::Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. :::::: == Experiential empiricism == ::::::The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: ::::::* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. ::::::* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). ::::::* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. ::::::* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. ::::::All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. ::::::I believe this is a valid contribution to Wikiversity. ::::::Best regards, ::::::Senad [[User:Senad Dizdarević|Senad Dizdarević]] ([[User talk:Senad Dizdarević|discuss]] • [[Special:Contributions/Senad Dizdarević|contribs]]) 06:54, 2 April 2026 (UTC) == Unable to publish pages == Whenever I try to publish a page with linked sources it gets flagged and says I'm a new user attempting to publish content with outside links.

Myself and students use some AI-generated images in the [[Motivation and emotion]] project. [[User:Dronebogus]] has been removing some of these images from Wikiversity pages and nominating them for deletion at Commons. As a result, some have been deleted and some have been kept. Dronebogus has made some useful edits and image suggestions for [[Motivation and emotion]] which I've appreciated and incorporated. However, there are other edits to remove an AI image by Dronebogus that I've reverted where I think the image is more educational than no image or an alternative image suggested by Dronebogus. There are a couple of pages where Dronebogus has reverted my reversion, so we are at risk of edit warring. We have briefly discussed and warned each other on our user talk pages, but it seems to come down to a difference in perception about the educational usefulness of the AI images. So, I'm asking here for others to please review the recent edit histories for these pages: * [[Motivation and emotion/Lectures/Brain and physiological needs]] * [[Motivation and emotion/Book/2025/Stockholm syndrome emotion]] and let us know what you think about the AI image suitability vs. using no image or alternative images suggested by Dronebogus.

I’m not reiterating the well known problems with generative AI— you can read about those on Wikipedia and the broader Internet. Needless to say it’s kind of just inherently toxic. If you use it, it should be the last resort of last resorts. Just my stance, which I consider perfectly valid and reasonable.

In contrast, AIPA targets the structural relationship between the self and the mind, aiming at durable identity reconstruction rooted in Pure Awareness rather than symptom management. ::::::The central research question of the primary AIPA preprint is whether a structured, sequentially staged method can produce permanent identity reconstruction rooted in Pure Awareness, and how such a method compares to established approaches in scope, mechanism, and outcome. :::::: == Theoretical foundations == ::::::The AIPA framework is grounded in the cognitive‑phenomenological tradition (e.g., McAdams, Varela, Metzinger, Erikson), contemporary consciousness science on minimal phenomenal experience, and qualitative methods advocacy in psychology. It builds directly on: ::::::* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. ::::::* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. ::::::* Narrative identity and partial‑self models within personality and identity theory. ::::::Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. :::::: == Experiential empiricism == ::::::The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: ::::::* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. ::::::* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). ::::::* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. ::::::* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. ::::::All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. ::::::I believe this is a valid contribution to Wikiversity. ::::::Best regards, ::::::Senad [[User:Senad Dizdarević|Senad Dizdarević]] ([[User talk:Senad Dizdarević|discuss]] • [[Special:Contributions/Senad Dizdarević|contribs]]) 06:54, 2 April 2026 (UTC) == Unable to publish pages == Whenever I try to publish a page with linked sources it gets flagged and says I'm a new user attempting to publish content with outside links.

This makes learning more practical and useful, especially for those who want to understand how real work environments function. ::'''Background''' ::The concept of online learning developed from distance education, where students learned from remote locations. Over time, with the growth of digital technology, learning has become more interactive and flexible. ::The introduction of the online internship has added another important layer to digital education. It combines theoretical learning with practical experience, helping students prepare for future careers. ::During global events such as the COVID-19 pandemic, online education and online internship programs became essential. They helped students continue learning and gaining experience despite restrictions on physical movement. ::'''Importance of Online Internship''' ::An online internship plays an important role in student development. It helps bridge the gap between academic knowledge and practical skills. ::'''Some key points include:''' ::Students understand how real work is done ::They develop basic professional skills ::It supports career readiness ::It allows learning without location limits ::By participating in an online internship, students can improve their confidence and gain early exposure to different fields. ::'''Features of Online Internship-Based Learning''' ::Modern education platforms often include online internship opportunities as part of their learning system.

Myself and students use some AI-generated images in the [[Motivation and emotion]] project. [[User:Dronebogus]] has been removing some of these images from Wikiversity pages and nominating them for deletion at Commons. As a result, some have been deleted and some have been kept. Dronebogus has made some useful edits and image suggestions for [[Motivation and emotion]] which I've appreciated and incorporated. However, there are other edits to remove an AI image by Dronebogus that I've reverted where I think the image is more educational than no image or an alternative image suggested by Dronebogus. There are a couple of pages where Dronebogus has reverted my reversion, so we are at risk of edit warring. We have briefly discussed and warned each other on our user talk pages, but it seems to come down to a difference in perception about the educational usefulness of the AI images. So, I'm asking here for others to please review the recent edit histories for these pages: * [[Motivation and emotion/Lectures/Brain and physiological needs]] * [[Motivation and emotion/Book/2025/Stockholm syndrome emotion]] and let us know what you think about the AI image suitability vs. using no image or alternative images suggested by Dronebogus.

Myself and students use some AI-generated images in the [[Motivation and emotion]] project. [[User:Dronebogus]] has been removing some of these images from Wikiversity pages and nominating them for deletion at Commons. As a result, some have been deleted and some have been kept. Dronebogus has made some useful edits and image suggestions for [[Motivation and emotion]] which I've appreciated and incorporated. However, there are other edits to remove an AI image by Dronebogus that I've reverted where I think the image is more educational than no image or an alternative image suggested by Dronebogus. There are a couple of pages where Dronebogus has reverted my reversion, so we are at risk of edit warring. We have briefly discussed and warned each other on our user talk pages, but it seems to come down to a difference in perception about the educational usefulness of the AI images. So, I'm asking here for others to please review the recent edit histories for these pages: * [[Motivation and emotion/Lectures/Brain and physiological needs]] * [[Motivation and emotion/Book/2025/Stockholm syndrome emotion]] and let us know what you think about the AI image suitability vs. using no image or alternative images suggested by Dronebogus. Sincerely, James -- [[User:Jtneill|Jtneill]] - <small>[[User talk:Jtneill|Talk]] - [[Special:Contributions/Jtneill|c]]</small> 11:45, 26 April 2026 (UTC) :I think Jtneill needs to try harder to find non-AI alternatives both on Commons and the web. I’m not reiterating the well known problems with generative AI— you can read about those on Wikipedia and the broader Internet. Needless to say it’s kind of just inherently toxic. If you use it, it should be the last resort of last resorts. Just my stance, which I consider perfectly valid and reasonable.

According to local tradition, the small Vietnamese kingdom of Au Lac, located in the heart of the Red River valley, was founded by a line of legendary kings who had ruled over the ancient kingdom of Van Lang for thousands of years. Historical evidence to substantiate this tradition is scanty, but archaeological findings indicate that the early peoples of the Red River delta area may have been among the first East Asians to practice agriculture, and by the 1st century BC they had achieved a relatively advanced level of Bronze Age civilization. • Vietnam conquered by French in 19th century • Occupied by Japanese in W.W.II • 1945 end of W.W.

However, rural area poverty also had some declination. In 1993, 66% and in 2002, 36%. Most of the poverty in Vietnam are in the rural areas in the northern parts of Vietnam and central highlands. Despite the progress, the [[World Economic Forum's 2005 Global Competitive Report]] ranked Vietnam as the 81st in growth competitiveness globally and 80th in business competitiveness. Ineffectiveness of the competition ranks are due to government corruption and poorly owned state banks. Economy in Vietnam is continuously growing at a rate of 7% per year.

According to local tradition, the small Vietnamese kingdom of Au Lac, located in the heart of the Red River valley, was founded by a line of legendary kings who had ruled over the ancient kingdom of Van Lang for thousands of years. Historical evidence to substantiate this tradition is scanty, but archaeological findings indicate that the early peoples of the Red River delta area may have been among the first East Asians to practice agriculture, and by the 1st century BC they had achieved a relatively advanced level of Bronze Age civilization. • Vietnam conquered by French in 19th century • Occupied by Japanese in W.W.II • 1945 end of W.W. II • 1946-54 – Communist Viet Minh League formed and led by Ho Chi Minh; not recognized by France • French and Viet Minh fight for control of Indochina • 1954 – Viet Nam divided with DMZ; elections promised by UN; country to be re-united in 1956 • 1955-6 Ho Chi Minh controls Communist North (DMV); Diem, supported by U.S. controls South; U.S. delays • 1957 – U.S. has Special Forces troops involved in intelligence gathering and training of South Vietnamese, including the Montagnard indigenous people, in guerilla warfare – no official involvement • 1963 – Pres. Diem assassinated; 3 weeks later, Kennedy assassinated • March 1965 – first U.S. combat troops land • October 1965 – first draft card burned • 1968 peace negotiations begin in Paris • 1969 My Lai massacre exposed • 1973 agreement signed between U.S. and DRV; official withdrawal of U.S. • 1976 N. and S.

However, rural area poverty also had some declination. In 1993, 66% and in 2002, 36%. Most of the poverty in Vietnam are in the rural areas in the northern parts of Vietnam and central highlands. Despite the progress, the [[World Economic Forum's 2005 Global Competitive Report]] ranked Vietnam as the 81st in growth competitiveness globally and 80th in business competitiveness. Ineffectiveness of the competition ranks are due to government corruption and poorly owned state banks. Economy in Vietnam is continuously growing at a rate of 7% per year. In 2003, tourism was at 2.4 million and 2004 international arrivals increased to 2.9 million. Between 1994 and 2004 tourism rates rose by 63%.

Nesse (1989) suggests that from an evolutionary point of view, it is most useful for a person to conserve energy when the outcome is unlikely to be a good one but to use all energy stores when the effort will result in good consequences. {| cellpadding="10" cellspacing="5" style="width: 100%; background-color: ForrestGreen; margin-left: auto; margin-right: auto" | style="width: 30%; background-color:Wheat; border: 3px solid YellowGreen; vertical-align: top; -moz-border-radius-topleft: 10px; -moz-border-radius-bottomleft: 10px; -moz-border-radius-topright: 10px; -moz-border-radius-bottomright: 10px;" <!--rowspan="2"--> |<div style="text-align: center"><p style ="line-height:20px;"><big>“Emotions are specialized modes of operation shaped by natural selection to adjust the physiological, psychological, and behavioural parameters of the organism in ways that increase its capacity and tendency to respond adaptively to the threats and opportunities characteristic of specific kinds of situations.” Nesse (1989, p. 268)</big> <br></p></div> |} ==Biophilia hypothesis== {| cellpadding="10" cellspacing="5" style="width:20%; background-color: ForrestGreen; margin-left: left; margin-right: auto" | style="width: 40%; background-color:Wheat; border: 3px solid YellowGreen; vertical-align: top; -moz-border-radius-topleft: 10px; -moz-border-radius-bottomleft: 10px; -moz-border-radius-topright: 10px; -moz-border-radius-bottomright: 10px;" <!--rowspan="2"--> |<div style="text-align: center"><p style ="line-height:20px;"><big>'''Please do this before reading on about the Biophilia Hypothesis'''</big> Which picture from each pair do you prefer?</p> <div style="column-count:3;-moz-column-count:3;-webkit-column-count:3"> <quiz display=simple> { 1st Pair |type="[]"} + [[Image:Field Hamois Belgium Luc Viatour.jpg|200px]] - [[Image:Wasteland - geograph.org.uk - 417442.jpg|200px]] { 2nd Pair |type="[]"} + [[Image:Pachaug Trail - Porter Pond, Sterling, CT.jpg|200px]] - [[Image:EAP-lobby-sw.jpg|200px]] { 3rd Pair |type="[]"} - [[Image:Stahlbau Pichler Maciachini Mailand.jpg|200px]] + [[Image:41 Cherry Orchard Road.JPG|200px]] </quiz> </div> This quiz examines preferences and introduces the topic. There are no right or wrong answers. </div> |} You may be asking, what has [[w:Evolution|evolution]] and emotion have to do with nature? We are beings with a fundamental need and desire to be affiliated with nature, according to the [[w:Biophilia_hypothesis |Biophilia Hypothesis]] (Khan, 1997; Wilson, 1984). This desire stems from our ancient history where we depended on the land and lived at the mercy of Mother Nature for almost 2 million years on the East African savannahs (Kahn, 1997). Observing the landscape to find bodies of water and food sources while keeping an eye out for predators was a part of daily life and is still ingrained in our subconscious minds. Psychological research has found that people have a preference for natural environments and built environments with natural features over built environments without natural features (Kaplan & Kaplan, 1989). This will be discussed further in environmental aesthetics and attention restoration theory, as they are both related to our general preference for natural environments and the benefits of nature to our well-being. The [[w:Biophilia_hypothesis|biophilia hypothesis]] suggests that the long history between humans and nature shaped our cognitions and emotions in a way that the modern human is now wired for an appreciation and evaluation of natural environments (Gullone, 2000). Those humans who had a genotype best for making behavioural responses most likely to enhance survival and reproduction were kept in the population through natural selection (Gullone, 2000). Behaviours in response to natural stimulation are either approach or avoidance behaviours. These adaptive behaviours are called biophilia and biophobia. Biophilia is the approach behaviour towards natural environments judge as fit for survival. Biophobia is the aversion and avoidance of potential dangers such as spiders, snakes and bears (Gullone, 2000). These behaviours are inherited from one generation to another and even when humans stopped living in a natural environment these rules, behaviours and stimuli responses did not disappear. '''Use nature to improve your life''' There is quite obviously a gap between today’s 21st century living habitats and that of our ancient ancestors. It has been suggested that reducing this gap and using the natural environmental is a good way to improve our psychological well-being and the quality of life (Buss, 2000). Being in touch with nature is one way to make you happy. It has been recommended that the differences between modern and ancestral living conditions be minimised and a [[w:Paleolithic_lifestyle|Paleolithic lifestyle]] to be taken up to increase psychological well-being (Buss, 2000). It is also recommended to develop deeper friendships rather than fair weather friends which reflects the society of our ancestors (Buss, 2000). These are some examples of how to keep ourselves close to our evolutionary roots and minimise the gap between now and then. == Environmental aesthetics== [[File:GoldenMedows.jpg|thumb|left|200px|Aesthetically Pleasing]] Environmental preference studies aim to determine the aesthetic value of a given stimuli using questionnaires, images and physical environments (Galindo & Rodriguez, 2000). There are various questionnaires that have been employed to measure the various components of environmental aesthetics. Descriptive scales have been used for describing the physical attributes in an environment or image. Affective scales measure moods and reactions to the stimuli. Appraisal scales indicate the aesthetic value of the settings (Galindo & Rodriguez, 2000). Many studies have concluded that people prefer park-like settings with short grass, mature trees and water (Balling & Falk, 1982). This indicates that we are inherently predisposed to judge [[w:Savanna|savannah]] like environments as more aesthetically pleasing than others. Such results support the biophilia hypothesis. The work of Daniel E. Berlyne explores the scientific study of aesthetic behaviour with a specific focus on the “appreciator” of the creation being viewed. His theory is developed in the evolutionist framework. He suggests that aesthetics play an important function in the survival of the human species. It is beneficial for humans to have an ability to detect aesthetically pleasing environments than to lack the ability. Natural selection would theoretically reduce the number of people in the population who did not possess these necessary abilities. The work of [[w:Rachel_and_Stephen_Kaplan|Rachel and Stephen Kaplan]] builds on that of Berlyne. Kaplan and Kaplan were concerned with the basic cognitive needs that people have with regard to their physical environments (Kaplan & Kaplan, 1989). These needs include the need to make sense of the environment and its features while extracting useful information. The second is the need to be involved in the environment (Galindo & Rodriguez, 2000). Environments that meet these needs generate responses of attraction and aesthetic preference in all individuals studied (Kaplan & Kaplan, 1989). An [[w:Evolutionist|evolutionist]] would say that avoiding environments that don't meet needs while approaching those which do, is a desirable and adaptive ability (Galindo & Rodriguez, 2000). {{RoundBoxTop|theme=9}} <big>Aesthetics, Pleasure and Arousal: Galindo & Rodriguez, 2000</big> {|border="1" cellpadding="5" cellspacing="0" align="right" |- ! scope="col" style="background:#F5DEB3;" | ! scope="col" style="background:#9ACD32;" | High Pleasure ! scope="col" style="background:#9ACD32;" | Low Pleasure |- ! scope="row" style="background:#9ACD32;" | High Arousal | Exciting || Distress |- ! scope="row" style="background:#9ACD32;" | Low Arousal || Tranquillity|| Boring |} Two independent and bipolar dimensions, pleasure and arousal, are used to describe the moods and affective responses that a person feels when observing an environment (Galindo & Rodriguez, 2000). The table demonstrates the four possible outcomes of when the two dimensions are low or high. The Galindo and Rodriguez (2000) study investigated the relationship between aesthetic judgements and affective responses/psychological well-being. Aesthetic appraisal responses were closely associated with arousal and pleasure, indicating that there is a relationship between environmental aesthetics and mood. {{RoundBoxBottom}} '''Use nature to improve your life''' This knowledge of human’s preferences for nature over human-made environments has many applications. For example, in a hospital ward there was a high sick-leave rate in staff before the installation of full spectrum daylight bulbs and green plants in 80m<sup>2</sup> on the premises. After the environmental aesthetic changes were made, there was a 32% reduction in tiredness, 25% drop in the sick-leave rate, 45% less headaches and 31% reduction in sore throats (Fjeld, 1998a, b). Are you a manager or boss in a company where you would like to reduce the sick-leave rate? How about investing in some green plants and [[w:Full-spectrum_light|full-spectrum]] daylight bulbs for the workplace and watch the way your employees react? ==Restorative environment & Attention Restoration Theory== Mental fatigue is the feeling of being worn out after working too hard for too long and feeling the need for a well-earned break. Everybody has experienced mental fatigue at some point, but it is interesting to note that you can feel mentally fatigued from working hard on projects you enjoy (Kaplan & Kaplan, 1989). Mental fatigue is often accompanied with the inability to focus and keep our attention on the project we are working on, instead distraction takes place and our minds wander. William James (1892) suggested that there are two types of attention; directed and involuntary. Involuntary attention is the type that doesn’t require any effort and is often used when there is something interesting to look at (Kaplan & Kaplan, 1989). Directed attention on the other hand is that which requires effort and drains our minds, such as a work project or an essay (Kaplan & Kaplan, 1989). Sleep can provide relief from this mental fatigue but the restorative experience is often more convenient. The restoration experience involves restoring our stores of directed attention while increasing our mental well-being by using involuntary attention. We can then return refreshed to do those things that need to be done. Attention Restoration Theory (Kaplan & Kaplan, 1989) proposes that a restorative experience involves four components. These are being away, the extent to which it feels like being in another ‘world’, fascination, and compatibility. [[File:Vrijbroekpark - by frank wouters.jpg|thumb|left|Restorative Experience]] '''Use nature to improve your life''' '''Being away''' Being away involves stopping mental effort and directed attention, escaping from distractions and from the work that is normally done. One does not need to be a long way from the workplace to escape from these things. An environment need only be distinctive and separate from the workplace. Perhaps you could try escaping to the nearby park during the lunch break to your eat lunch and while you are there, watch the birds and animals in the park? '''Extent of other worldliness''' The extent to which the environment is different to your usual place is important because without the distinctiveness it will not be a restorative experience. A place that can be described as a ‘whole other world’ is an important property of the environment to which you escape to. A garden where there is more to explore and see in the garden than what one sees at first sight is another important part of extent. Kaplan and Kaplan (1989) suggest that Japanese gardens are the best for this as the miniature effect creates a sense of distinctiveness and uniqueness. If you are in the process of landscaping, consider a garden that encourages exploration using hidden features and overgrown pathways. '''Fascination''' Fascination is the next key to the restorative experience to help you regain mental well-being. Fascination involves involuntary attention and therefore keeps the person from getting bored but also there is no effort needed for attention to take place. Wild animals, sunsets, waterfalls, caves, fires, stars, clouds can all grab our involuntary and effortless attention if we let them and are called soft fascinations. They should not hold our attention for too long (otherwise they become too distracting to pull ourselves out) and they should be aesthetically pleasing. Go and watch the clouds go by on a day when you’ve had enough of work. At night watch the stars in your backyard. These forms of soft fascinations will allow your directed attention to have a break and its stores to refill while your involuntary attention takes over for a while. '''Compatibility''' Compatibility and relatedness come back to the evolutionary perspective and the biophilia hypothesis. That is, that on an innate and inherited level we as humans prefer natural environments to human-made environments and we feel a sense of awe and wonder when in its presence. Relatedness and compatibility can occur in these natural environments. Psychological well-being occurs when we are in a compatible environment. Being in an incompatible environment requires a lot of effort and attention. Next time you are finding it hard to read a difficult text due to distractions at work, head to a park bench and immerse yourself in a compatible restorative environment. {{RoundBoxTop|theme=9}} <big>Restorative environments through a hospital window (Ulrich, 1984)</big> The recovery records of 46 cholecystectomy (gall bladder surgery) patients from a Pennsylvania hospital were examined. The aim was to explore the difference in recovery rates of those with a window facing a brick wall and those who had a view of foliage. The patients were grouped into 23 pairs based on sex, age, smoking habits, and weight and floor level. Results for the months between 1st of May and October 20th for the years 1972 to 1981 were used, because as during these months the trees had foliage. The length of hospitalisation for those with a tree-view was 7.96 days while those with a view of a brick wall stayed in for 8.70 days. Nurses’ notes on the wall-view patients indicated that they were in a more negative mood than those in the tree-view room, although it was not statistically significant. Those in the tree-view room took fewer moderate to strong pain killers than the wall-view patients in the 2-5 days after surgery. Ulrich noted that the brick wall view was quite hideous and boring. He suggests that a view of another built environment, such as a busy street, may produce different results because the patient is more stimulated. The results of the 1984 study suggest that natural environments do indeed provide a restorative environment which improves both physical and mental well-being. {{RoundBoxBottom}} ==Nature Deficit Disorder== [[File:Eye to Eye.jpg|thumb|left|Children with Nature]] Author of “[[w:Last_Child_in_the_Woods|Last Child In the Woods]]”, [[w:Richard Louv| Richard Louv]] has suggested that the children of today’s society are missing out on vital interaction with nature. [[w:Nature deficit disorder|Nature Deficit Disorder]], as Louv puts it, is the cause of the rise in obesity, attention disorders and depression. Nature Deficit Disorder is not recognised as an official disorder, however many of the points Louv raises relate to the current chapter. The book is recommended for parents who are worried about the health of their children and their lack of direct exposure to nature. The main features of Louv’s Nature Deficit Disorder theory are based around the relationship between children and nature. He suggests that there is a new relationship between child and nature in which children do not interact with the natural world as much as they should. Secondly, he suggests that we all need direct exposure to nature in our lives and without it mental fatigue, irritability and agitation creep in. Thirdly, Louv suggests that busy schedules and fear keep our children from enjoying nature. Thankfully his book “[[w:Last_Child_in_the_Woods|Last Child In the Woods]]” also provides ways to reunite children and nature (see tips for more). Please keep in mind that this disorder is currently not in the [[w:Diagnostic_and_Statistical_Manual_of_Mental_Disorders |DSM]] and therefore not accepted by general psychiatry. Further research and theory development is needed before acceptance as a mental disorder. {{RoundBoxTop|theme=9}} <big>Vegetation and children: Wells and Evans (2003)</big> Wells and Evans collected data from 337 rural children from five small towns in upstate New York. They were in grades 3 to 5 with an average age just over nine years. Parents reported the psychological distress shown by their children on the Rutter Child Behaviour Questionnaire. Children provided their own ratings of global self-worth on the Harter Competency Scale. The authors explored the impact of nearby nature on children subject to a stressful life event. To assess the frequency of stressful life events, the Lewis Stressful Life Events Scale was used. As expected, exposure to stressful life events correlated with psychological distress. Secondly, nearby nature was found to be a moderator between stressful life events and psychological distress. There was a large difference between the psychological distress of children who had low exposure to nature and those who had high exposure to nature. Those with high exposure to nature had less distress than those with low exposure to nature even though they had the same levels of stressful life events. The effect was particularly large when there were high levels of stressful life events. {{RoundBoxBottom}} '''Use nature to improve your life''' Children who experience high levels of stressful life events would benefit from living nearby nature. If this is not an option, consider investing in a veggie patch or building a cubby house in your backyard. Whether you believe your child is distressed or not, encourage your children to be active in the outdoors. If you have a busy schedule, consider allocating time to throwing a ball around outside with your child. It will be good for you as well as your child! == Seasonal Affective Disorder == [[File:Schneelandschaft Furx.JPG|thumb|A winter without Sun]] Biological changes occur on a continuum throughout the year and while many people may feel lethargic and irritable in the colder and darker months of the year (Eagles, 2003), on the extreme end of this continuum is [[w:Seasonal_affective_disorder|Seasonal Affective Disorder]] which impairs the functioning of those who suffer with it. Seasonal Affective Disorder (SAD) is a disorder in the [[w:Diagnostic_and_Statistical_Manual_of_Mental_Disorders|DSM-IV]] that presents as major depression with a seasonal pattern (Targum & Rosenthal, 2008). People with SAD slow down and lose energy in the darker months of the year and often have trouble waking in the morning. There can also be problems with concentration and weight gain which can be caused from excessive eating of sweets and other starchy foods (Targum & Rosenthal, 2008). SAD is most common in the winter months where there is relatively little sun (Rosenthal, 2009). Severe SAD can cause major depressive symptoms on cloudy days (Targum & Rosenthal, 2008). Research has suggested that patients with SAD can have more severe symptoms than clients with non-seasonal major depression who have attempted suicide (Pendse, Engstroem & Traeskman-Bendz, 2004). Treatment is necessary for those who have SAD. {{RoundBoxTop|theme=9}} <big>Melatonin, Bright Light Therapy and Dawn Simulation: Avery et al, 2001; Terman et al, 2001.</big> [[w:Melatonin|Melatonin]] is a natural hormone which is used by all mammals to indicate that darkness is approaching and that it is time for rest. Research has suggested that the longer hours of darkness cause an imbalance to the melatonin rhythm and this is why people become more lethargic in the darker months (Brown, Pandi-Perumal, Trakht & Cardinali, 2010). Bright light therapy and dawn simulation both attempt to fix the melatonin imbalance and rhythm and restore proper sleep and mood ((Avery, Eder, Bolte, Hellekson, Dunner, Vitiell & Prinz, 2001; Terman, Terman & Cooper, 2001). To help reset the melatonin rhythm, bright light treatment is best administered in the morning eight and a half hours after melatonin onset(Terman et al., 2001). Bright light therapy has been criticised for the inconvenience caused to the patient. Dawn simulation has been suggested as a better for the treatment of SAD (Avery et al, 2001). Dawn simulation is the use of dim lights slowly increasing in intensity until the patient wakes up and simulates the rising of the sun in the morning (Avery et al., 2001). Compliance of the patient is greater with dawn simulation than bright light therapy because it saves time and is very convenient (Avery et al., 2001). {{RoundBoxBottom}} '''Use nature to improve your life''' Having knowledge of SAD can help you identify if this applies to you and what natural light treatments are available. Read "Winter Blues: Everything You Need to Know to Beat Seasonal Affective Disorder" by [[w:Norman_E._Rosenthal|Norman Rosenthal]] for more information. You should consult your doctor or psychologist for further information and diagnosis of SAD. ==Green exercise== [[File:What is green exercise.svg|thumb|left|Table 1. ''Components of Green Exercise'']] Physical activity and exposure to nature both have positive effects on psychological well-being and physical health (Pretty, Peacock, Sellens & Griffin, 2005). Table 1 shows the components that define [[w:Green_exercise|green exercise]]. Combining physical exercise and exposure to nature it termed green exercise and may promote even better physical and mental health than either one alone. [[Green_exercise]] incorporates environmental aesthetics and restorative environments. Engagement with nature can be seen on three levels (Mackay & Neill, 2010): viewing nature, being in the presence of nature, and being involved in nature. Green exercise is about being involved in nature. Gardening, jogging outdoors, watersports and mountain biking can be considered as green exercise. {{RoundBoxTop|theme=9}} <big>Exercise and projected scenes: Pretty et al. 2005</big> {| border="1" cellpadding="5" cellspacing="0" align="right" |- ! scope="col" style="background:#9ACD32;"|Condition ! scope="col" style="background:#9ACD32;"|Example |- !scope="col" style="background:#F5DEB3;" | Control | No Image |- !scope="col" style="background:#F5DEB3;" |Rural Pleasant | Trees, fields etc |- !scope="col" style="background:#F5DEB3;" |Urban Pleasant | Cityscape with natural features ie city parks |- !scope="col" style="background:#F5DEB3;" |Rural Unpleasant | Broken down cars in the bush etc |- !scope="col" style="background:#F5DEB3;" |Urban Unpleasant | Broken windows, wire fencing etc |- |} There were five conditions with 20 participants. In four of the conditions 30 scenes were projected onto a wall whilst the participants exercised on a treadmill. Blood pressure, self-esteem and mood were measured before and after the exercise. Results indicated that in the control group exercise reduced blood pressure and improved self-esteem and mood. When exercise was paired with pleasant scenes the mood and self-esteem of participants was higher than in other conditions. Unpleasant scenes when paired with exercise reduced the effect of exercise on self-esteem and self-esteem was lower in these conditions. {{RoundBoxBottom}} '''Use nature to improve your life''' [[File:Mountain bike ParcoSibillini.jpg|thumb|Green exercise]] Next time you hop on your treadmill, consider facing it towards a window where you can see outside. Or go one step further and go for a jog outside, go hiking or go canoeing on the local lake. Being motivated to exercise can be hard, so check out the [[Motivation and emotion/Book/Exercise motivation|Exercise Motivation chapter]] for some tips. == Miscellaneous tips on how to use nature to improve your life== * Give flowers to a woman. When you do she will produce a [[w:Smile#Duchenne smiling|Duchenne smile]] and will be in a more positive mood for 3 days. (Haviland-Jones, Rosario, Wilson & McGuire, 2005). * Make your backyard into a habitat for native flora and fauna. Build a bird bath and plant natives (requires less watering than non-natives and they look great). * Go hiking and camping. Light a fire and star gaze at night (please check local fire bans beforehand). * Be in nature and be aware of your senses. Listen, smell, touch and watch (Louv, 2008). Try the [http://wilderdom.com/games/descriptions/SensualAwarenessInventory.html Sensual Awareness Inventory] for this activity. * Plant a veggie garden. Good for saving money on produce. Great for the kids to see where their food comes from and be involved in the process (Louv, 2008). ==Summary== Lessons about nature and psychological well-being can be learnt from the research and theories of environmental and evolutionary schools of psychology. This chapter was written to help you realise that nature plays a vital role in our psychological well-being. You now know that: * You can use restorative environments to reduce mental fatigue. (Attention Restoration Theory) * Being in touch with nature and our ancestral roots can improve your life. (Environmental Aesthetics & Biophilia Hypothesis) * Children need nature for their mental health. (Nature Deficit Disorder) * Emotions can be dramatically affected by the change of seasons. (Seasonal Affective Disorder) * Combining exercise with nature is best. (Green exercise) The take away message from the chapter is this: '''go outdoors and use nature to improve your life'''. ==See also== * [http://www.acfonline.org.au/news-media/acf-opinion/ten-reasons-why-we-need-more-contact-nature Ten reasons why we need more contact with nature] * [[Motivation and emotion/Book/Animals and emotion|Animals and emotion: How connection with animals can improve emotion and well-being]] * [[Motivation and emotion/Book/Weather and emotion | Weather and Emotion: How the weather effects our emotions]] * [[/Transcript/|Transcript for the 5 minute audiovisual chapter overview]] == References == {{Hanging indent| Avery, D.H., Eder, D.N., Bolte, M.A., Hellekson, C.J, Dunner,D.L., Vitiello, M.V., & Prinz, P.N.

The greater the distance between provinces the stronger the difference. Directly the difference between Hanoian and Saigon, Mekong was once called a dialect difference. Nowadays, the education for all of Vietnam includes the Hanoian dialect. However, each ethnic tribe can have less national education between parents, and may still have a different dialect or vocabulary. ====In computers==== Currently, there are speaking programs that use the Vietnamese language properly. A commonly available Mozilla Add-on for the Firefox web browser can read Vietnamese (or text) with the 'vietnamization' that is needed. It's called Vietnamese TTS. TTS means Text to Speech. Audio libraries are available to reproduce the Vietnamese language. [http://translate.google.com Google translate] uses a TTS reader and sound library to read Vietnamese in simple sentences. Hand held versions are also very popular. [http://www.kimtudien.vn/ Kim Tu Dien] makes the most common pocket dictionary for the Vietnamese market. {{RoundBoxBottom}} {{RoundBoxTop|theme=4}} ===Script=== ====Alphabet==== The [[Vietnamese 1/Alphabet|Vietnamese alphabet]]. ====Vietnamese dipthongs==== The combination of two vowels makes a dipthong. The dipthongs used in the Vietnamese language have some rules when used. For example, one rule states where the singular tone marking for both letters must be placed. ====Vietnamese tripthongs==== There are more tripthongs in Vietnamese than English. 'uye' is included. ====Vietnamese syllables==== The syllables refers to the Chinese use of at least two characters as syllables. So, Hong is one and Kong the other. Vietnamese also uses singular syllables as words (monosyllabic). For example: in the same way as English, people can say just 'go'. For more emphasis (in Vietnamese) it could be said twice. The use of the syllable twice is from the history of languages for Asia. Some Australian Aboriginal languages are known do the same thing <ref>http://en.wikipedia.org/wiki/Wiradjuri</ref>. So, 'go - go' (đi đi)<ref>http://vi.wikipedia.org/wiki/Silva_Kaputikyan</ref> means definitely go. But also, 'go' would have been enough in Vietnamese. Many singular syllables are used by the Vietnamese language. They can form sentences without pairing with other syllables as they do in [[Portal:Chinese|Chinese]]. Readers (and speakers) still notice that many syllables, in most sentences, are paired. ===Vietnamization=== Many words from around the world were needed in Vietnamese. When a word gets vietnamization it is changed to sound Vietnamese. [[Portal:Chinese|Chinese]] uses the same method of conversion Ao-day-lia in Pinyin means Australia. ====The first rule==== The first rule for vietnamization is that ''''no Vietnamese word/syllable is broken by a consonant''''. E.g. ([http://vi.wiktionary.org/wiki/Việt_Nam Việt Nam]). An example of how to break a foreign word into two syllables is '''[http://vi.wiktionary.org/wiki/mô_tô mô tô]''' which is used for motorbike. It's not the most common word for motorbike, but it is accepted. This word is a vietnamized version of 'motor' and 'auto'([http://vi.wiktionary.org/wiki/ô_tô ô tô]). <br> But, the rule isn't used in every vietnamization of a word, e.g. [http://vi.wiktionary.org/wiki/lôgic lôgic]. When introducing a common foreign word, people 'vietnamize' the word in at least one spoken demonstration for Vietnamese listeners. *This rule should explain a problem with the foreign use of the name Nguyen. It will never be New Yen! '''Y''' is not a consonant in [[Comparative law and justice/Vietnam|Vietnam]]. A better explanation is by comparing the English name ''Ian'' to any name with '''Yen'''( e.g. Yến). This use of '''Y''' has an equal in English: many, penny, etc use the vowel 'y'. ====The second rule==== The second (softer) rule for vietnamization is that the sound of each syllable must be made 'a little closer to Viet sounds'. The second rule is made to work by adding the tone marks for vowel letters. For example: [http://vi.wiktionary.org/wiki/lôgic lôgic]is an alteration of 'logic'. It would be needed to teach a couple of school and science subjects. Computer science uses this word. ====Exceptions==== Any word can be made an exception to vietnamization. *Names like Barak Obama, or Bill Clinton might be attempted by all Vietnamese speakers. In writing, these foreign names will mostly stay intact. *Names like David are easy for Vietnamese people to say, and have become very popular in English-class textbook writing. *Chemistry has various exceptions to Vietnamization rules. A chemical name may stay intact in script, but vietnamized in speaking. *Computer jargon and proprietary names may remain completely intact with only slight accent differences when speaking. {{RoundBoxBottom}} {{RoundBoxTop|theme=2}} ==Grammar== ===Sentence beginnings=== * sau đó, (after that) * trước khi, (before when) * mình yêu, (I love) * Tôi đang ở, (I am at) * anh có, (you (fellow) have) * ở chợ, (at the market) * Có hạt, (Has nut) * đây là, (this is) * Đúng, tôi, sẽ được (Correct, I will be able) * Xin anh, (Please, you) * đi ủi, (To iron/press, Go iron) * Mang cho tôi,(Bring for me) {{RoundBoxBottom}} {{sisterlinks|Vietnamese}} ==References== {{Reflist}} [[Category:Vietnamese]] [[Category:Grammar]] 15rg14l93b9g3kx6fxcqezl0q2z21ss Linux System programming in plain view 0 136794 2809781 2807820 2026-05-17T01:00:33Z Young1lim 21186 /* File System */ 2809781 wikitext text/x-wiki This course belongs to the [[Electrical & Computer Engineering Studies]] == Introduction == * Introduction ([[Media:SysP.Intro.20161128.pdf|pdf]]) == File System == * File System ([[Media:SysP.FileSystem.20251023.pdf|pdf]]) * File Pointer ([[Media:SysP..FilePointer.20161103.pdf|pdf]]) * System Calls ([[Media:SysP.File.SysCall.20161128.pdf|pdf]]) * File IO ([[Media:SysP.FileIO.20251023.pdf|pdf]]) * Copilot: File System ([[Media:glibcFileSystem.20251029-2.pdf|pdf]]) * Copilot: File Buffer ([[Media:glibcFileBuffer.20251025-2.pdf|pdf]]) * Copilot: File IO ([[Media:glibcFileIO.20251025-2.pdf|pdf]]) * Copilot: File Permission ([[Media:glibcFilePerm.20260121.pdf|pdf]]) * Copilot: File Control ([[Media:CP.FileCntl.20260428.pdf|pdf]], [[Media:CP.FileCntl.A.20260511.pdf|A]], [[Media:CP.FileCntl.B.20260504.pdf|B]], [[Media:CP.FileCntl.C.20260501.pdf|C]]) <br> <br> == Process == * Process ([[Media:SysP.Process.20251120.pdf|pdf]]) * Fork ([[Media:SysP.Fork.20251126.pdf|pdf]]) * Copilot: Process Information ([[Media:glibc.Process.1Info.20251101.pdf|pdf]]) * Copilot: Process Control ([[Media:glibc.Process.2Control.20251103.pdf|pdf]]) * Copilot: Process Execution ([[Media:glibc.Proc.3Exec.20251105.pdf|pdf]]) * Copilot: Process Fork ([[Media:glibc.Proc.4Fork.20251106.pdf|pdf]]) * Copilot: Process Context Switching ([[Media:glibc.Proc.5Context.20251107.pdf|pdf]]) * Copilot: Process Exec family of functions ([[Media:glibc.Proc.6ExecCall.20251112.pdf|pdf]]) * Copilot: Process Wait family of functions ([[Media:glibc.Proc.7WaitCall.20251112.pdf|pdf]]) * Copilot: Process Exit ([[Media:glibc.Proc.8Exit.20251113.pdf|pdf]]) </br> == Inter Process Communication== === Signal === * Signal ([[Media:SysP.7.A.Signal.20121206.pdf|pdf]]) * Copilot: Signal 1.

wikitext text/x-wiki {{Policy|WV:CUR}} [[File:Wikiversity Curator.svg|right|130px|link=]] '''Curators''' are part of [[Wikiversity]]'s [[Wikiversity:Support staff|support staff]]. They can [[#Deletion of pages|delete]] pages, use [[Wikiversity:Rollback|rollback]], [[Wikiversity:Import|import]] from other wikis, and [[#Edit and move protection of pages|protect]] and unprotect pages. == How does one become a curator? == {{shortcut|WV:CUR/HOW}} Any [[Wikiversity:Who are Wikiversity participants?|Wikiversity participant]] willing to do a lot of [[#What can curators do?|dull and boring work]] for the community can become a curator. If you have a good editing record, then you are likely to be trusted and granted the privileges and responsibilities of curatorship. If you are still interested in being a curator, here is the process: {| style="border-collapse: collapse" border="1" cellpadding="4" | style="padding: 10px; text-align: center" | I | <div id="Request"> ;Request </div> You must request or be nominated for curatorship at [[Wikiversity:Candidates for Curatorship]]. State your reasons for seeking this position and in what areas you are or would like to be active. You may also refer to your contributions and indicate whether you have similar responsibilities at other projects. |- | style="padding: 10px; text-align: center" | II | <div id="Mentorship"> ;Mentorship </div> [[Wikiversity:List of custodian mentors|Custodian mentors]] are expected to guide and advise you on the appropriate use of curator privileges in accordance with established policy and community consensus. If any experienced custodian agrees to mentor you and you agree to their mentorship, then you will be approved as a curator. If you have any questions or concerns, you should contact your mentor(s) for guidance and advice. If you or your mentor terminate the mentorship agreement, you will have 48 hours to find a new mentor. Otherwise, your mentor may remove curator privileges after 48 hours without any further notice or community discussion. |} == What can curators do? == {{shortcut|WV:CUR/WHAT}} === Deletion of pages === {{see also|Wikiversity:Deletions}} [[File:Delete and Protect buttons.png|200px|right]] {{shortcut|WV:CUR/D}} Curators can delete pages including images, categories, templates, and so on. Deletion is subject to [[Wikiversity:Policies|policy]]. Deletion requests may be submitted by any user at [[Wikiversity:Requests for Deletion]]. Deleting a page does not actually remove it from the database. It merely becomes invisible to non-custodians and can be restored at request via [[Wikiversity:Requests for Deletion]]. Page deletions and restorations can be monitored by viewing the [[Special:Log/delete|deletion log]]. Curators may delete pages, but they do not have undelete rights. Before deleting a page, you are encouraged to read: [[Wikiversity:Welcome templates]]. === Edit and move protection of pages === {{See also|Wikiversity:Page protection}} Curators can [[Wikiversity:Page protection|protect pages]] to prevent editing. There are two types of page protection: semi-protection, which prevents anonymous and new users from editing, and full protection, which prevents all non-custodians and non-curators from editing. A page can also be protected to prevent moving. Page protection can be lifted by any custodian or curator upon request at [[Wikiversity:Request custodian action]]. Page protections and unprotections can be monitored by viewing the [[Special:Log/protect|protection log]]. === Rollback === {{see also|Wikiversity:Rollback}} [[Image:Rollback button.png|thumb|300px|Rollback button]] Curators have a ''[[Wikiversity:Rollback|rollback tool]]'' to revert the last change or group of changes made to a page by the same user. There is no option to provide an edit summary when using this tool. Instead, a summary such as "{{int:Revertpage}}" will be used automatically. This tool is primarily used to respond to obvious vandalism. For other edit reversions, the rollback button should not be used and a good edit summary should be provided. === Import === {{see also|Wikiversity:Import}} Curators have access to the [[Special:Import|import tool]], to bring in materials from projects such as Wikipedia, Wikibooks, Beta Wikiversity, Wikiquote, and Wikisource. == What can't curators do? == Curators cannot [[Wikiversity:Blocking policy|block users]] or assign user rights, as these actions require [[Wikiversity:Custodianship|custodian]] and [[Wikiversity:Bureaucratship|bureaucrat]] permissions, respectively. Removal of custodian and bureaucrat permissions can only be done by [[m:Steward requests/Permissions|stewards]] at Meta-Wiki. == How are curators expected to act? == {{shortcut|WV:CUR/E}} Curators are supposed to follow the same principles as every other user, including [[Wikiversity:Civility|being civil]], [[Wikiversity:Assume Good Faith|assuming good faith]], and understanding [[Wikiversity:What is Wikiversity?|what Wikiversity is]]. They are expected to act professionally, and to respect policy and [[Wikiversity:Consensus|community consensus]]. ==Problems with curators== {{shortcut|WV:CUR/P}} If you have a question about an action (page deletion, page protection, violation of Wikiversity policy or some other action that does serious damage to the project) by a Wikiversity curator, the first thing to do is leave a message on that curator's user discussion page. Curators should always be able to explain how their actions support the Wikiversity project. If you did not get a satisfactory answer after a discussion with the curator, follow up with their mentor. Actions of a curator are ultimately the responsibility of their mentor(s). Any custodian may remove a curator's rights, but first try to resolve all curator problems by discussion. Post a request at [[Wikiversity:Request custodian action]] if discussion does not successfully resolve the issue. == Inactivity == The maximum period of curator inactivity without [[Wikiversity:Community Review|community review]] is two years, consistent with the [[:meta:Category:Global policies|global policy]] at [[meta:Admin activity review|Admin activity review]] that applies for [[Wikiversity:Custodianship#Notes|Custodians]] and [[Wikiversity:Bureaucratship|Bureaucrats]]. Where a curator has been inactive for this period, notice should be placed on their talk page using {{tl|Inactive curator}}). If no response in received after one month, a Custodian may remove the rights. == Notes == {{shortcut|WV:CUR/N}} * Curatorship is a responsibility, not a right. While everyone is encouraged to apply for curatorship, the position is not suited for everyone. Please also note that in all instances not listed above, curators have no more power or weight than other users. "Curatorship is not a big deal." * Curators should set their "user preferences" so as to provide for email contacts from other Wikiversity participants. If you do not use email, then you must make yourself easily available by some other means such as [[Wikiversity:Chat|IRC chat]]. == Useful reads for curators == ===Wikiversity=== * [[Wikiversity:No shrines for vandals]] * [[Wikiversity:Policies]] * [[How to be a Wikimedia sysop/Wikiversity]] ===MediaWiki/Wikimedia=== * [[How to be a Wikimedia sysop]] * [[b:MediaWiki Administrator's Handbook|MediaWiki Administrator's Handbook]] ==See also== * [[Special:ListUsers/curator|List of current Wikiversity curators]] * [[Wikiversity:Bureaucratship]] * [[Wikiversity:Custodianship]] * [[Wikiversity:Support staff|Wikiversity:Staff]] [[Category:Wikiversity administration]] [[Category:Wikiversity curatorship]] [[Category:Wikiversity user roles]] 2byn1c7bnkazkpg905996yq3u8b5ahq Modern Hebrew 0 205559 2809833 2788805 2026-05-17T03:47:37Z HenriPittier 3076895 2809833 wikitext text/x-wiki [[File:Flag of Israel.svg|500px]]<br> Modern Hebrew is the feces of the Hebrew language spoken in Israel today.

I am deeply committed to fostering the community of complex systems and am eager to contribute to the organisation of this talented group. I am particularly interested in the “living roadmap” of CS-DC, a unique feature that operates through two complementary strategies. Firstly, it addresses major transversal problems, and secondly, it focusses on classes of complex systems. This integrative systems framework is particularly pertinent to geosciences, which are increasingly integrating urban sciences, sustainability science, territorial planning, computational modelling, socio-ecological intelligence, and digital governance. Consequently, TIME—Territorial Intelligence for Multilevel Equity and Sustainability—is built on this integration process and is one of CS-DC’s principal flagship projects. I possess extensive international experience as a scientist, mentor, leader, organiser, and editor, which I believe would be valuable assets to this role. Sincerely, Daniel Schertzer [https://hmco.enpc.fr/team-view/daniel-schertzer/ Short CV of Daniel Schertzer] '''Flavia Mori SARTI, Ph.D., Professor and Researcher, University of Sao Paulo, Brazil''' I present my interest in being candidate for the CS-DC Executive Committee to contribute to the dissemination of knowledge in complex systems at the local and global level. I am representative of the University of Sao Paulo (USP) at the CS-DC since 2012. I work with complex systems modeling since the creation of the Interdisciplinary Research Group of Complex Systems Modelling at the School of Arts, Sciences and Humanities (EACH-USP) in 2006. Our research group succesfully implemented the first interdisciplinary graduate program titled Master in Complex Systems Modeling in Brazil, in 2010. I have been participating in the program commission since 2010, and I was coordinator of the graduate program from 2010 to 2014. I have supervised 12 students in the program and two postdoctoral fellows, followed by publication of several book chapters and papers on complex systems applied to public policies, including models on tax evasion, health systems regulation, health insurance, food policy and nutrition programs, and complex networks on scientific collaboration and global food trade. I have been invited to present seminars and talks on complex systems applied to food systems, health economics, and public policy. My goals in the CS-DC Executive Committee include: * To disseminate the role of CS-DC in education and research on complex systems, especially in developing countries; * To support and to engage other research groups working with complex systems for participation in the CS-DC; * To contribute further with management and organization of CS-DC activities during the period of 2022-2024; * To continue supporting capacity building in complex systems through supervision and other academic activities; * To foster innovation, research and development strategies through complex systems applications in public policy and entrepreneurship. '''Alberto A. Rasia-Filho, MD, Ph.D, Professor and Researcher, Federal University of Health Sciences of Porto Alegre (UFCSPA) and Federal University of Rio Grande do Sul (UFRGS), Brazil''' Dear Councilors of the UNESCO CS-DC, It is an honor to submit my candidacy for the CS-DC Executive Committee for 2026. Please let me introduce myself as a Full Professor of Physiology (UFCSPA), Supervisor in the Biosciences (UFCSPA) and Neuroscience Graduate Programs (UFRGS), and a researcher on human neuronal morphology, dendritic spines, synaptic plasticity, and social/emotional neural networks (National Council for Scientific and Technological Development, Brazil). Professional Identifier/ORCID: 0000-0003-4623-5916. Currently, I am participating as head of the e-Team "Morphological Heterogeneity" in the UNESCO CS-DC, led by Prof. Enver Oruro Puma, Principal Investigator of the Morphodynamic Neuroscience and Behavior eLab CS-DC, and Prof. Grace E. Pardo, Scientific Research Institute, Continental University of Cusco, Peru. We integrate morphodynamics across different scales of brain organization and neural network functions in complex systems, considering neuronal morphology itself as an emergent level of organization. The structure of neural cells and their connectivity within the brain volume are morphodynamic features with interactions from cellular morphogenetic elements, the local cell neighborhood, and synaptic connections. In turn, the emergent functions of networks are organized around a series of conceptual, experimental, and computational foundations. These ideas were developed—and are now open to additional discussions—in the recent article from our group: “New Directions for Complex Systems in Contemporary Neuroscience: A Morphodynamic and Emergent Function Approach” (Research Topic: Theoretical and Computational Insights into Brain-Based Cognition/Frontiers in Computational Neuroscience). This represents an ongoing research line available for further collaborations in Complex Systems Science. I will be (1) committed to the Action Plan 2026 (and beyond) from the current 2026-31 Action Plan/Complex Systems Digital Campus UNESCO UniTwin, (2) working to integrate interdisciplinary approaches and eTeams, sharing knowledge and opportunities for complex systems education and research, as well as (3) contributing to country and continent engagement and representation in line with worldwide aims, (4) including the academic formation of young scientists. ----'''Norberto Garcia-Cairasco, BSc, MSc, PhD, Full Professor of Physiology-Neurophysiology, Ribeirão Preto School of Medicine, University of São Paulo (FMRP-USP), Ribeirão Preto, São Paulo State, Brazil.''' Dear Councilors of the UNESCO CS-DC, It is an honor for me to submit my candidacy for the CS-DC Executive Committee for 2026. Please, let me introduce myself as a Full Professor of Physiology-Neurophysiology, Ribeirão Preto School of Medicine, University of São Paulo (FMRP-USP), Ribeirão Preto, São Paulo State, Brazil. At FMRP-USP, I am Supervisor (Master and PhD) at both Graduate Programs in Physiology and Neurology/Neuroscience & Neuropsychiatry. I have been the Founder and the Director for almost 40 years of the Neurophysiology and Experimental Neuroethology Laboratory, where we conduct research in the characterization of epilepsies and associated neuropsychiatric comorbidities, using behavioral, electrophysiological, cellular, molecular and computational integrated tools, in both experimental and collaborative clinical settings. Our main funding comes from the State of São Paulo Foundation (FAPESP), the Federal agencies National Council for Research (CNPq) and the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES). Professional Identifier/ORCID: <nowiki>https://orcid.org/0000-0001-8857-3775</nowiki>. I am currently the Head of the e-Team “'''Epilepsy and Neuropsychiatric Comorbidities”''' in the UNESCO CS-DC, led by Prof. Enver Oruro and Prof. Grace E Pardo, Principal Investigators of the Neurocomputing, Social Simulation, and Complex Systems Laboratory at the Instituto Científico of Universidad Continental del Cusco, Peru. Complex systems are involved in abnormal functioning and the refractoriness to pharmacological approaches of epileptogenic neural circuits, with additional multilevel complexity derived from associated, usually neuropsychiatric comorbidities. We, indeed, propose that the morphodynamics of neurons and glia in neural circuits can be studied as an initial step toward understanding proper wiring and stable properties, including neurotransmitters, neuromodulators, receptors, and intracellular signal transduction components, as well as plastic features, environmental stimuli, attention, and learning. These ideas were developed, and are now open to additional discussions, in the recent article from our group: “New Directions for Complex Systems in Contemporary Neuroscience: A Morphodynamic and Emergent Function Approach” (Research Topic: Theoretical and Computational Insights into Brain-Based Cognition/Frontiers in Computational Neuroscience). This represents an ongoing research line available for further collaborations in Complex Systems Science. I will be (1) committed to the Action Plan 2026 (and beyond) from the current 2026-31 Action Plan/Complex Systems Digital Campus UNESCO UniTwin, (2) working to integrate interdisciplinary approaches and eTeams, sharing knowledge and opportunities for complex systems education and research, as well as (3) contributing to country and continent engagement and representation in line with worldwide aims, (4) including the academic formation of young scientists. In addition to the above-mentioned agenda and goals, I will offer, for the leverage of outreach activities, my experience of more than four decades in the '''''Neuroscience & Arts''''' connection. In fact, I am co-Founder of the “Brain Awareness Week” in Brazil (since 2012) and currently the Coordinator at the Institute for Advanced Studies at USP-Ribeirão Preto of the “'''''Science, Arts, Education and Society Network - ScienArtES'''''”. In 2022, I received the Title of ''Doctor Honoris Causa'' (Biology) from the Universidad de Salamanca, Spain. Finally, I am also, since 2026, a Member of the Brain Literacy Initiative Alliance: Uniting for Brain Research-Informed Education Worldwide. ---- == Candidature for the New President for [2025, 2026] == '''Manifesto – Candidature for New President of UNESCO UniTwin CS-DC''' '''Prof. Paul Bourgine''' : If elected, my main commitment is to create the conditions for a self-organized development of our UNESCO UniTwin CS-DC as autonomous communities of communities for our flagship TIMES and its Knowledge & Knowhow Accelerator one-for-all & all-for-one (KKA). We know now how to realize —for the two above commitments— the 3<sup>rd</sup> UNESCO commitment, i.e., the ‘computational ecosystem’. It will use the mature part of Web 3.0, especially the InterPlanetary File System (IPFS). Thanks to our previous efforts especially of the two last years, the remaining work amount is ten times less than we were anticipating at the beginning of the 2<sup>nd</sup> renewal of our UniTwin by UNESCO 2020-2026.   If elected, my duty will be not only to fulfill entirely the commitments of our Cooperation Program with UNESCO but also starting an exponential increasing development wave for our UniTwin network (through their continent and country Councils) and of our e-Campus (through CS-DC’25 and e-Labs’26 Conferences especially for our Flagships for sustainable development). The Knowledge & Knowhow Accelerator will directly benefit from 1) such conference series, 2) our past and new flagships for sustainable development and 3) a new decentralized strategy for collecting donations in our decentralized network of X-Legal Entities. == New Candidatures to the Executive Committee for [2025] == === Manifesto – Candidature for the Executive Committee of UNESCO UniTwin CS-DC === '''Prof. Silvius STANCIU, PhD in Economics, PhD in Engineering, Habil.'''

I am very honored to place my candidature for the UNESCO UniTwin CS-DC Executive Committee. I am Enver Miguel Oruro Puma, Ph.D., principal investigator of Neurocomputing, Social Simulation, and Complex Systems Laboratory at the Instituto Científico of Universidad Andina del Cusco, Peru (https://sites.google.com/view/orurolab/). Since 2009, I have promoted and organized conferences and academic events on Complex Systems in Latin America. Recently, I have promoted the area of computational neuroscience on infant attachment (https://sites.google.com/view/envermiguel/seminar-in-maternal-infant-relationship-studies). It would be a great honor for me if given the opportunity to contribute to the Executive Committee of UNESCO UniTwin CS-DC in the integration of Complex System research groups in the Latin American Region. For this, I propose the creation of two periodical activities: 1) A Special Lectures Series on Complex Systems UNESCO UniTwin CS-DC oriented to experts on Complex Systems, and 2) A Invited Advanced Lectures UNESCO UniTwin CS-DC oriented to experts who do not identify explicitly with complex systems '''Pierre Collet, full professor of Strasbourg University, on secondment to Universidad Andrés Bello, Instituto de Tecnología para la Innovación en Salud y Bienestar, Viña del Mar, Valparaiso, Chile'''. Since 2012, I have contributed to the elaboration of the CS-DC Unesco UniTwin together with Paul Bourigne, Jeffrey Johnson and many others, and I have been co-coordinator of the CS-DC UniTwin with Cyrille Bertelle since its creation in 2014. Starting part of this great adventure has changed my academic and personal life: thanks to the UniTwin, I have changed my research from stochastic optimisation, artificial evolution and AI in general to complex systems and epistemology. Participating in this UniTwin allowed me to make new contacts and start incredible projects that I could not have imagined before. It has even changed my life, as I am now living in Chile, having been recruited by ITISB, an institute founded by Carla Taramasco, the CS-DC representative for South America. Together with Paul and others, we would like to revive UniTwin by preparing another world conference inspired by the great success of [https://cs-dc-15.org CS-DC'15] and also develop flagship projects such as POEM (Personalised Open Education for the Masses) and the [https://en.wikiversity.org/wiki/Portal:Complex_Systems_Digital_Campus/E-Laboratory_on_complex_computational_ecosystems ECCE e-lab], which this year has welcomed a new very active [[Figures of Play/Les figures du Jeu e-team|Figures of Play]] that has started the [https://ludocorpus.org/ Ludocorpus] in France. As said before, this incredible UniTwin adventure always pays off for those who invest in it and in its great challenge: to develop the new science of complex systems through research and education. Through its projects, it contributes to making the world a better place to live in, despite the constant attacks on science coming from the most unlikely places. Science is the solution, not the problem, to many of the world's plagues. We must put our energy into developing it and defend it against all its detractors. That is why I am once again standing for election to the Executive Committee of this great CS-DC UniTwin. Modern science is Complex Systems science. It is important that its beacon continues to illuminate the world, and we must invest our time and energy in it. == Candidature Deputy President for [2024, 2025] == '''Jeffrey JOHNSON, Professor of Complexity Science and Design, The Open University, UK''' I offer myself as a candidate both to be President and to the Executive Committee of The UNESCO UniTwin Complex Systems Digital Campus (CS-DC) so that I can help to drive it forward to achieve it goals. I am particularly committed to our educational efforts. I have made four MOOCs on the FutureLearn Platform for CS-DC ( <nowiki>https://www.futurelearn.com/partners/unesco-unitwin-complex-systems-digital-campus</nowiki> ): Global Systems Science (2015-16); Systems Thinking and Complexity (2017-18); First Steps in Data Science with Google Analytics (2018-19) and COVID-19 - Pandemics, Modelling and Policy (2020). CS-DC has a great opportunity to become the global university providing interdisciplinary education for a better world. I am also committed to our research mission with UNESCO towards the achieving the U.N. Sustainable Development Goals. My own research on representing the dynamics of complex multilevel systems is relevant to many of the research initiatives of CS-DC. I have extensive experience working within the complex systems community. I have run various coordination actions supporting research programmes funded by the European Commission, I am a founder member and past president of the Complex Systems Society, and I am Deputy-President of the CS-DC. I believe this experience will enable me to make a significant contribution the CS-DC over the next three years. == New Elected President for [2023, 2024] == Paul BOURGINE, present President of the UNESCO UniTwin CS-DC, Complex Systems Institute of Paris I offer myself as a candidate to be President of The UNESCO UniTwin Complex Systems Digital Campus (CS-DC). My previous commitment two years ago is below. The bad news is that it was not achieved. The good new is that we know now how to create 'autonomous community of autonomous communities' as a social network with IPFS (the InterPlanetary File System) like the new development of Wikipedia. If elected, my first commitment is to finish this job as quickly as possible. My second commitment is simultaneously to visit each country of the UniTwin for creating its country.CS-DC and its roadmap with young eTeams shared by their Universities with a senior scientific committee.

BARRIOS H., PhD., Professor, Bucaramanga, Colombia ''' I write to express my interest to candidacy to be part of the CS-DC Executive Committee. I'm very motivated to develop actions to strengthen digital ecosystem supporting research and education proposals of our CS-DC Council. Among these years participating in the CS-DC group, I can see different ways to leverage the impact and the development of our actions with computational strategies, and now, I want to be part of the leadership council joined mutual visions. My experience leading the Advanced Computing System for Latin America and Caribbean (SCALAC : http://scalac.redclara.net ) and as member of other leadership boards in international projects (mainly between Europe and Latin America) supports my candidature. (linkedin.com/in/carlosjaimebh) Also, my role as professor, director and researcher contributes to build the common vision of the CS-DC Council and the leadership of the CS- DC Executive Committee. '''Mina TEICHER, Professor of Bar-Ilan University, Israël''' I submit my candidacy to the Executive Committee of the CS Digital Campus. If elected I will work towards our following needs, using my past experience in Professional international societies, universities managements and the data industry :  * We need in the near future to build an optimal and effective agreement with the Complex System Society. * We need to build a business  plan for fund raising. * We need to build a modular budget for 2021. * We need to build a strategy for geographically extension.  * We need to build a strategy for thematic  extension.  * We need to build partnerships with the big multi national high tech Companies in network and in content.  '''Yasmin MERALI, Professor of University of Hull, UK''' This manifesto is connected with the ideals that I had as a founding member of our UniNet which was conceived as part of the FP7 ASSYST project. CS-DC has come a long way since its initial conception. The way I see it, there are three categories that have grown to emerge as our core activities- * Capacity building through education and training in Complex Systems Science * The application of Complex Systems Science to address global challenges * The advancement of Complex Systems Science through research and development. I believe this is a good time to link back to the inception of our UNITWIN which was in part inspired by considerations of issues at a human scale, and the desire to address the inequalities that divided the so-called developed and developing countries. This resonates strongly with the ambition of the Sustainable Development Goals (SDGs) we are currently grappling with. In the growth phase of the UNITWIN and CSDC we have been focused on extending the size of the network, and scaling up our educational offerings across the digital campus. In the next phase I believe we need to: # understand and leverage the diversity and distinctive capabilities and resources (e.g. indigenous knowledge) of the countries in our network to develop a healthy ecosystem, and # tailor the support that we provide to align with the diverse nature of their relational and social capital and their economic, political and environmental challenges and priorities with regard to the SDGs. I am concerned that if we do not explicitly design a social/ideational exchange mechanism that attends to these two imperatives, we will not have full, active participation of all member institutions, and the countries of the South that do not currently have champions in Europe will be marginalized. If elected I would champion a strategy of organizing ourselves following the Complex Adaptive Systems paradigm, as a hyper network with dynamically connected local clusters. In practical terms I would like to begin by establishing the local (country-based) clusters and establishing a discourse that would allow us to map the diverse profiles, challenges and aspirations for the different countries. This would then form the basis for the development of a mechanism for shaping the meaningful collaborative development of our three core activities to deliver advances that are globally co-ordinated and locally responsive. Personal Profile: I am Professor of Systems Thinking at the University of Hull and have served as Director of the Centre Systems Studies there. Prior to that I was Co-Director of the Doctoral Training Centre for Complex Systems Science at the University of Warwick. My research is transdisciplinary, focusing on the use of Complex Systems Science to enhance the resilience of socio-economic systems. I am an Expert advisor to the EU and I have significant experience of lecturing internationally as Visiting Professor in Asia, Europe and the USA. '''Céline ROZENBLAT: Professor, University of Lausanne - Institut de géographie et de durabilité (IGD), Switzerland''' I'm pleased to applied to become member of the CS-DC council. As founding member of CS-DC, my university, the university of Lausanne, is very engaged in Complex sciences. I would not only represent my university, but also social science as geographer and vice-president of the International Geographical Union and member of the International Science Council commission on Urban Health and Well being. I would act in the council in specific programs to develop the reality of the Digital Campus of the Complex systems. All these actions combine very ambitious interdisciplinary approaches, and in this perspective, we developed with CS-DC for 3 years the TIMES Flagship Territorial Intelligence For Multilevel Equity And Sustainability. It comprises four main programs: '''SIRE''': Socially Intelligence Roadmap Ecosystem '''POLE:''' Personalized Open Lifelong Education '''WOSI:''' Worldwide Open Smart Innovation '''WOSP:''' Worldwide Open Stochastic Prediction In this perspective a MOOC « Healthy Urban system » is now in development, basing the interdisciplinary approach on the CS-DC Road-Map grid. It seems very useful and relevant in this implementation stage. I would help to develop other programs in this perspective\[Ellipsis] '''André TINDANO, Director General of CARFS (African Center for Research and Training in Synecoculture)''' What motivates me to aspire to the position of member of the executive committee of CS DC is my long term participation in the promotion of sustainable development and my commitment to the sharing of knowledge and expertise. My research interests Sustainable agriculture, ecology, nutrition, life science. I have a strong experience in: * Administration and management of development projects and programs; * Accompaniment of associations and groups; * Technical capacity building (animation of training sessions and reflection workshops). * Action research; * Sociological, socio-economic and economic studies. * Development of development projects and programs; * Training of trainers * Results Based Management Training (RBM) * Monitoring and evaluation of development programs and projects; * Management of programs and development projects; * Institutional development and organizational strengthening; * Development and implementation of training / awareness / animation program; * Very good knowledge of participatory methods '''Guiou KOBAYASHI, Associate Professor at Federal University of ABC in São Paulo State, Brazil. ''' I worked with fault-tolerant computer systems for nuclear power plants and Metro signaling systems and recently my interests have evolved to resilience properties of Complex Systems. Traditionally, redundancy was the main feature for fault-tolerant and fail-safe systems, but the adaptability and the evolution of Complex Systems are the key elements for the resilience of these systems. How to characterize, design and implement these key elements in our future resilient systems? The Complex System - Digital Campus (CS-DC) is a way to create a world-wide community of researchers, philosophers and students to promote and discuss this kind of questions involving Complex Systems. For me, participating in its foundation was a great honor and I am very glad for the opportunity that I have had to contribute since 2012 in the consolidation of CS-DC. Through this manifest I am applying to be one of the members of the new CS-DC's Executive Committee. I would like to help just a little more to strengthen and structure this fantastic community through which I had the opportunity to meet important people with very interesting works that expanded my knowledge of Complex Systems. Although my University and my personal contribution for CS-DC are very limited and small, I hope to continue to work with this great team. '''Pierre COLLET, Professor of Computer Science, University of Strasbourg, France. Co-coordinator of the CS-DC UNESCO UniTwin''' The CS-DC initiated by Paul Bourgine, Jeffrey Johnson, Cyrille Bertelle and many others has been an extraordinary adventure a) to instantiate as a UNESCO UniTwin and b) to develop and run since it was enacted in July 2014. Many a night have been spent on designing its inner workings, so that it can deliver an effective affordance for the scientists who wish to develop the science and teaching of Complex Systems. Indeed, many projects seeded in the CS-DC have come to fruition, showing the enormous potential of this fertile environment not only for research, but also for teaching: the BBB rooms set up by the CS-DC have not only made it possible for the CS-DC to organize conferences, but have also shown their potential as remote teaching rooms in many Universities around the world. It has been an honour for me to be part of the development of the CS-DC since its beginning, but so much remains to be done! In this manifesto, I hereby express my strong desire to continue developing the CS-DC in these trying times, when the effects of the pandemics stretch thin the social links that our research and teaching communities need most. My objectives for this new mandate are not only to deliver a new world conference (originally planned in 2020 but unfortunately delayed due to the high toll imposed on us all, teachers and researchers alike, by COVID-19) but also continue on developing not only efficient complex computational ecosystems (cheap powerful PARSEC machines have been installed in several universities) but more specifically remote teaching environments based on complex systems, to mitigate the terrible impact of the pandemic on face to face education, within the POEM CS-DC flagship, on which Paul Bourgine and myself have been working for many years now.. '''Mariana C. BROENS, Professor - UNESP - BRAZIL.''' As members of the Executive Committee, our main challenge will be to raise, analyse and to discuss possible positive/negative ethical and political implications of the further development of the Complex Systems Science, and their application on studies of everyday social problems. In particular, We believe that the widespread use of complex system models and Big Data analytics can bring important questions about people's privacy, personal and corporate responsibility, widespread surveillance by public or private institutions, among many others, that should be deeply discussed in our community. Our contribution will be to raise and deepen these discussions from an interdisciplinary perspective. '''Cyrille Bertelle, Professor in Computer Sciences, University Le Havre, France, co-coordinator of the CS-DC UNESCO UniTwin''' I am a candidate for the CS-DC Executive Committee to represent the University of Le Havre Normandy, which is co-coordinator with the University of Strasbourg of the convention of recognition of the CS-DC as UniTwin by UNESCO. The University of Le Havre has made available to the community, resources and skills to provide digital collaborative tools for the organization of the Councils and the CS-DC'15 virtual conference. The objective I wish to take is to facilitate the involvement of member universities not only by their representatives on the council but by allowing researchers from these member institutions to join concrete and accessible actions. Co-responsible in the past of a master's degree on complex systems and then of the creation of the institute on complex systems in Normandie (France) in a multidisciplinary framework, I have participated in the setting up of the project labeled by the French national program of investments for the future and entitled "Smart Port City". The aim is to think about the future of territories in a sustainable development approach supported by new technologies and concerned about the environment and the well-being of their citizens. My research skills are focused on implementing the complexity of complex dynamic systems and networks, crossing behavioral scales from the interaction of human behaviors to the technical networks of the territory. The book "complex systems, smart territories and mobility" from the Springer's Understanding Complex Systems series, which will be published in January 2021 (https://www.springer.com/gp/book/9783030593018) illustrates the research coordination actions that I lead in these fields. '''Slimane Ben Miled, Senior Researcher at Pasteur Institute of Tunis, Professor at ENIT''' Our Tunisian consortium want to constitute a collaborative Research Training Programs to increase data science capacity related to health research in Africa by building trainings and enhancing institutional capacity at African academic institutions. The academy/project is based on 4 pillars to build a training ecosystem for Data and Engineering Science in health. # A platform of federated master’s programs with à la carte optional courses covering informatics/computer science, biomedical informatics, data science, statistics, and public health). Each program will keep its independence, with a mention to the academy label, and this platform will allow to enrich the training with optional modules, seminars, and courses in the partner institutions. New curricula will be created in relation to ethical issues. # Network of Doctoral programs and Executive programs # Platform of federated Business incubator and a career center offers training, support and funding for projects related to the project’s topic. This challenge is in perfect agreement with the Sustainable Development Goal 3 and the CS-DC flagship PHYSIOMES (Personalized Health phYSIcally, sOcially and Mentally for Each in their networkS). '''Masa Funabashi: researcher of open complex systems at Sony Computer Science Laboratories, Inc.''' I would like to contribute to the executive committee of CS-DC on the following two pillars: * Promote the FOOD (From smart agrOecOnomy to smart fooD) flagship project that aims to resolve the health-diet-environment trilemma through the promotion of sustainable food systems, in collaboration with the e-lab "human augmentation of ecosystems" members institution: Sony CSL, Synecoculture Association, CARFS, and those who wish to participate in CS-DC collaboration. * Construct a basic e-learning content on Synecoculture and ecological literacy as a part of CS-DC MOOCs and perform initial trials, principally in ECOWAS countries, through the Sony CSL-CARFS collaboration. Through the development of on-going activities in FOOD project and making synergy with other flagship projects, I would like to contribute CS-DC as a member of the executive committee and realize further extension toward the achievement of global sustainability goals such as SDGs.

In case of invasion, it can affect the agriculture and pastures of about 25 countries including those of the poorest countries of the world, from Mauritania to India, while its best and most effective strategy of struggle is preventive struggle by targeting its first centers of gregarization which are very small in space and much better known today. In 2005, the costs of its struggle in the Sahel and North Africa amounted to half a billion dollars, with 8 million farmers and pastoralists affected in the Sahel. It also massively invaded Asia and Africa. 'East Africa in 2020.

László Barna Iantovics, Associate Professor at “George Emil Palade” University of Medicine, Pharmacy, Science and Technology of Targu Mures, Romania.''' With the present manifesto, I would like to candidate as a member of the CS-DC Executive Committee. I am the representative of “George Emil Palade” University of Medicine, Pharmacy, Science and Technology of Targu Mures from Romania in CS-DC. Some of my research and academic activities are related to the complex systems, including: publications, organization of conferences (e.g. Symposium on Understanding Intelligent and Complex Systems - UICS 2009; 1st Int. Conf. on Complexity and Intelligence of the Artificial and Natural Complex Systems Medical Applications of the Complex Systems. Biomedical Computing -CANS 2008; 1st Int. Conf. on Bio-Inspired Computational Methods Used for Difficult Problems Solving. Development of Intelligent and Complex Systems - BICS 2008), contribution to conference committees (e.g. Int. Conf. Emergent Proprieties in Natural and Artificial Complex Systems - EPNACS 2007; Workshop on Complex Systems and Self-organization Modeling -CoSSoM 2009), preparing journal special issues (e.g. Special Issue on Complexity in Sciences and Artificial Intelligence; Special Issue on Understanding Complex Systems), participating in journal’s editorial board (e.g. Complex Adaptive Systems Modeling -CASM, SpringerOpen), and contribution to research in projects and projects coordination (Social network of machines- SOON; Hybrid Medical Complex Systems -ComplexMediSys). I was the director of the center Advanced Computational Technologies – AdvCompTech in the frame of my university. At present, I am the director of the Center for Advanced Research in Information Technology from my university. I would like much deeper involve myself in the life and activities of the CS-DC community. My objectives: * To involve junior and senior researchers from my university in activities regarding research and education. To motivate universities and research institutes from my country to contribute to CS-DC. I consider also universities and research institutes with that I have collaboration in the past. * To PROPOSE the formation of a so-called doctoral and postdoctoral students group. In the case of doctoral and postdoctoral students probably in time more students would like to be involved in activities. In this framework, I suggest the organization yearly 3 times (from 4 to 4 months) workshops in that all the interested students could discuss, present their research and research in progress. With this occasion in the frame of workshops if there is interest could be established separate sessions with presentations also by B.Sc. and M.Sc. students. * To PROPOSE the strengthening of the following research direction with the general topic: intelligent complex systems and machine intelligence measuring. One of the subtopic by interest will be complex systems approaches in medicine and healthcare. To be accomplishable this subject I propose in a first step the formation of a group of interested persons, after then the establishment of the functionality of the group, for example: discussions when are subjects that should be discussed etc. ==Elected members to the Executive Committee & as (Deputy-)Presidents== '''Jeffrey JOHNSON, Professor of Complexity Science and Design, The Open University, UK''' I offer myself as a candidate both to be President and to the Executive Committee of The UNESCO UniTwin Complex Systems Digital Campus (CS-DC) so that I can help to drive it forward to achieve it goals. I am particularly committed to our educational efforts. I have made four MOOCs on the FutureLearn Platform for CS-DC ( https://www.futurelearn.com/partners/unesco-unitwin-complex-systems-digital-campus ): Global Systems Science (2015-16); Systems Thinking and Complexity (2017-18); First Steps in Data Science with Google Analytics (2018-19) and COVID-19 - Pandemics, Modelling and Policy (2020). CS-DC has a great opportunity to become the global university providing interdisciplinary education for a better world. I am also committed to our research mission with UNESCO towards the achieving the U.N. Sustainable Development Goals. My own research on representing the dynamics of complex multilevel systems is relevant to many of the research initiatives of CS-DC. I have extensive experience working within the complex systems community. I have run various coordination actions supporting research programmes funded by the European Commission, I am a founder member and past president of the Complex Systems Society, and I am Deputy-President of the CS-DC. I believe this experience will enable me to make a significant contribution the CS-DC over the next three years. '''Paul BOURGINE, present President of the UNESCO UniTwin CS-DC, Complex Systems Institute of Paris''' I offer myself as a candidate both to be President and to the Executive Committee of The UNESCO UniTwin Complex Systems Digital Campus (CS-DC). If elected, my main commitment is to create the conditions for a self-organized development of our UniTwin UNESCO CS-DC as autonomous communities of communities. This self-similar development will be the case both for the two main branches the UniTwin branch of our institutional members and the global eCampus branches of our individual scientific members: * for the UniTwin branch, the communities of communities are a territorial cascade with Smart Continents, smart countries, smart cities for their sustainable development according our flagship TIMES (Territorial Intelligence for Multilevel Equity and Sustainability). The roadmap is always the same, i.e. the cascade of the 17 Sustainable Development Goals and their 169 Targets: but their relative importance and coherence within this cascade vary from one territory to the others. The institutional members of the UniTwin branch have signed their agreement with the Cooperation Programme signed with UNESCO. In 2021, the CS-DC will ask for a cascade of agreements inside each institutional member, in order to have a "one for all" amplification within the other branch, the e-campus branch. * for the eCampus branch, the cascade of communities is along the refinement cascades when studying the theoretical and experimental challenges of complex systems. With Smart Continents'21, scientists are proposing their individual challenges that enact basic communities and communities of communities within the e-departments. In the "all for one" return, the roadmap of each university is the cascade of roadmaps within the eCampus where the University has at least one member. Furthermore each community can organise a monthly e-seminar or e-session in workshop as well as in CS-DC'21 for recorded advanced introductions. Such advanced introductions can be the basis for curriculum largely shared by the set of Universities having members in the community cascade of the curriculum. This "accelerator of knowledge and knowhow one for all and all for one" will first benefit to the student curriculum through the flagship POEM (Personalized Open Education for the Masses). This accelerator can be extended through the flagship POLE (Personalized Open Lifelong Education) for a lifelong education. This extended accelerator will be open to all, independently of previously achieved academic levels, respectful of the diversity of social and cultural environments and in a higher and higher inclusive way including refugees, migrants and primary people. genders, religions or ways of life. n30cbxh7arc8o84ximpzzycpzk67aym 2809678 2809675 2026-05-16T18:11:30Z ~2026-29396-85 3076712 /* Daniel Schertzer, Ecole nationale des ponts et chaussées */ 2809678 wikitext text/x-wiki ---- ----<nowiki>**</nowiki>Please ''login'' in Wikiversity and then use the ''<nowiki/>'edit''' button: your edition mode will be 'WYSIWYG'.

I am deeply committed to fostering the community of complex systems and am eager to contribute to the organisation of this talented group. I am particularly interested in the “living roadmap” of CS-DC, a unique feature that operates through two complementary strategies. Firstly, it addresses major transversal problems, and secondly, it focusses on classes of complex systems. This integrative systems framework is particularly pertinent to geosciences, which are increasingly integrating urban sciences, sustainability science, territorial planning, computational modelling, socio-ecological intelligence, and digital governance. Consequently, TIME—Territorial Intelligence for Multilevel Equity and Sustainability—is built on this integration process and is one of CS-DC’s principal flagship projects. I possess extensive international experience as a scientist, mentor, leader, organiser, and editor, which I believe would be valuable assets to this role. Sincerely, Daniel Schertzer [https://hmco.enpc.fr/team-view/daniel-schertzer/ Short CV of Daniel Schertzer] '''Flavia Mori SARTI, Ph.D., Professor and Researcher, University of Sao Paulo, Brazil''' I present my interest in being candidate for the CS-DC Executive Committee to contribute to the dissemination of knowledge in complex systems at the local and global level. I am representative of the University of Sao Paulo (USP) at the CS-DC since 2012. I work with complex systems modeling since the creation of the Interdisciplinary Research Group of Complex Systems Modelling at the School of Arts, Sciences and Humanities (EACH-USP) in 2006. Our research group succesfully implemented the first interdisciplinary graduate program titled Master in Complex Systems Modeling in Brazil, in 2010. I have been participating in the program commission since 2010, and I was coordinator of the graduate program from 2010 to 2014. I have supervised 12 students in the program and two postdoctoral fellows, followed by publication of several book chapters and papers on complex systems applied to public policies, including models on tax evasion, health systems regulation, health insurance, food policy and nutrition programs, and complex networks on scientific collaboration and global food trade. I have been invited to present seminars and talks on complex systems applied to food systems, health economics, and public policy. My goals in the CS-DC Executive Committee include: * To disseminate the role of CS-DC in education and research on complex systems, especially in developing countries; * To support and to engage other research groups working with complex systems for participation in the CS-DC; * To contribute further with management and organization of CS-DC activities during the period of 2022-2024; * To continue supporting capacity building in complex systems through supervision and other academic activities; * To foster innovation, research and development strategies through complex systems applications in public policy and entrepreneurship. '''Alberto A. Rasia-Filho, MD, Ph.D, Professor and Researcher, Federal University of Health Sciences of Porto Alegre (UFCSPA) and Federal University of Rio Grande do Sul (UFRGS), Brazil''' Dear Councilors of the UNESCO CS-DC, It is an honor to submit my candidacy for the CS-DC Executive Committee for 2026. Please let me introduce myself as a Full Professor of Physiology (UFCSPA), Supervisor in the Biosciences (UFCSPA) and Neuroscience Graduate Programs (UFRGS), and a researcher on human neuronal morphology, dendritic spines, synaptic plasticity, and social/emotional neural networks (National Council for Scientific and Technological Development, Brazil). Professional Identifier/ORCID: 0000-0003-4623-5916. Currently, I am participating as head of the e-Team "Morphological Heterogeneity" in the UNESCO CS-DC, led by Prof. Enver Oruro Puma, Principal Investigator of the Morphodynamic Neuroscience and Behavior eLab CS-DC, and Prof. Grace E. Pardo, Scientific Research Institute, Continental University of Cusco, Peru. We integrate morphodynamics across different scales of brain organization and neural network functions in complex systems, considering neuronal morphology itself as an emergent level of organization. The structure of neural cells and their connectivity within the brain volume are morphodynamic features with interactions from cellular morphogenetic elements, the local cell neighborhood, and synaptic connections. In turn, the emergent functions of networks are organized around a series of conceptual, experimental, and computational foundations. These ideas were developed—and are now open to additional discussions—in the recent article from our group: “New Directions for Complex Systems in Contemporary Neuroscience: A Morphodynamic and Emergent Function Approach” (Research Topic: Theoretical and Computational Insights into Brain-Based Cognition/Frontiers in Computational Neuroscience). This represents an ongoing research line available for further collaborations in Complex Systems Science. I will be (1) committed to the Action Plan 2026 (and beyond) from the current 2026-31 Action Plan/Complex Systems Digital Campus UNESCO UniTwin, (2) working to integrate interdisciplinary approaches and eTeams, sharing knowledge and opportunities for complex systems education and research, as well as (3) contributing to country and continent engagement and representation in line with worldwide aims, (4) including the academic formation of young scientists. ----'''Norberto Garcia-Cairasco, BSc, MSc, PhD, Full Professor of Physiology-Neurophysiology, Ribeirão Preto School of Medicine, University of São Paulo (FMRP-USP), Ribeirão Preto, São Paulo State, Brazil.'''

Please, let me introduce myself as a Full Professor of Physiology-Neurophysiology, Ribeirão Preto School of Medicine, University of São Paulo (FMRP-USP), Ribeirão Preto, São Paulo State, Brazil. At FMRP-USP, I am Supervisor (Master and PhD) at both Graduate Programs in Physiology and Neurology/Neuroscience & Neuropsychiatry. I have been the Founder and the Director for almost 40 years of the Neurophysiology and Experimental Neuroethology Laboratory, where we conduct research in the characterization of epilepsies and associated neuropsychiatric comorbidities, using behavioral, electrophysiological, cellular, molecular and computational integrated tools, in both experimental and collaborative clinical settings.

Complex systems are involved in abnormal functioning and the refractoriness to pharmacological approaches of epileptogenic neural circuits, with additional multilevel complexity derived from associated, usually neuropsychiatric comorbidities. We, indeed, propose that the morphodynamics of neurons and glia in neural circuits can be studied as an initial step toward understanding proper wiring and stable properties, including neurotransmitters, neuromodulators, receptors, and intracellular signal transduction components, as well as plastic features, environmental stimuli, attention, and learning.

Starting part of this great adventure has changed my academic and personal life: thanks to the UniTwin, I have changed my research from stochastic optimisation, artificial evolution and AI in general to complex systems and epistemology. Participating in this UniTwin allowed me to make new contacts and start incredible projects that I could not have imagined before. It has even changed my life, as I am now living in Chile, having been recruited by ITISB, an institute founded by Carla Taramasco, the CS-DC representative for South America.

Through its projects, it contributes to making the world a better place to live in, despite the constant attacks on science coming from the most unlikely places. Science is the solution, not the problem, to many of the world's plagues. We must put our energy into developing it and defend it against all its detractors. That is why I am once again standing for election to the Executive Committee of this great CS-DC UniTwin. Modern science is Complex Systems science. It is important that its beacon continues to illuminate the world, and we must invest our time and energy in it. == Candidature Deputy President for [2024, 2025] == '''Jeffrey JOHNSON, Professor of Complexity Science and Design, The Open University, UK''' I offer myself as a candidate both to be President and to the Executive Committee of The UNESCO UniTwin Complex Systems Digital Campus (CS-DC) so that I can help to drive it forward to achieve it goals. I am particularly committed to our educational efforts. I have made four MOOCs on the FutureLearn Platform for CS-DC ( <nowiki>https://www.futurelearn.com/partners/unesco-unitwin-complex-systems-digital-campus</nowiki> ): Global Systems Science (2015-16); Systems Thinking and Complexity (2017-18); First Steps in Data Science with Google Analytics (2018-19) and COVID-19 - Pandemics, Modelling and Policy (2020). CS-DC has a great opportunity to become the global university providing interdisciplinary education for a better world. I am also committed to our research mission with UNESCO towards the achieving the U.N. Sustainable Development Goals. My own research on representing the dynamics of complex multilevel systems is relevant to many of the research initiatives of CS-DC. I have extensive experience working within the complex systems community. I have run various coordination actions supporting research programmes funded by the European Commission, I am a founder member and past president of the Complex Systems Society, and I am Deputy-President of the CS-DC. I believe this experience will enable me to make a significant contribution the CS-DC over the next three years. == New Elected President for [2023, 2024] == Paul BOURGINE, present President of the UNESCO UniTwin CS-DC, Complex Systems Institute of Paris I offer myself as a candidate to be President of The UNESCO UniTwin Complex Systems Digital Campus (CS-DC). My previous commitment two years ago is below. The bad news is that it was not achieved. The good new is that we know now how to create 'autonomous community of autonomous communities' as a social network with IPFS (the InterPlanetary File System) like the new development of Wikipedia. If elected, my first commitment is to finish this job as quickly as possible. My second commitment is simultaneously to visit each country of the UniTwin for creating its country.CS-DC and its roadmap with young eTeams shared by their Universities with a senior scientific committee. The eTeam projects will have the opportunity to be submitted to the EU calls or other ones.

BARRIOS H., PhD., Professor, Bucaramanga, Colombia ''' I write to express my interest to candidacy to be part of the CS-DC Executive Committee. I'm very motivated to develop actions to strengthen digital ecosystem supporting research and education proposals of our CS-DC Council. Among these years participating in the CS-DC group, I can see different ways to leverage the impact and the development of our actions with computational strategies, and now, I want to be part of the leadership council joined mutual visions. My experience leading the Advanced Computing System for Latin America and Caribbean (SCALAC : http://scalac.redclara.net ) and as member of other leadership boards in international projects (mainly between Europe and Latin America) supports my candidature. (linkedin.com/in/carlosjaimebh) Also, my role as professor, director and researcher contributes to build the common vision of the CS-DC Council and the leadership of the CS- DC Executive Committee. '''Mina TEICHER, Professor of Bar-Ilan University, Israël''' I submit my candidacy to the Executive Committee of the CS Digital Campus. If elected I will work towards our following needs, using my past experience in Professional international societies, universities managements and the data industry :  * We need in the near future to build an optimal and effective agreement with the Complex System Society. * We need to build a business  plan for fund raising. * We need to build a modular budget for 2021. * We need to build a strategy for geographically extension.  * We need to build a strategy for thematic  extension.  * We need to build partnerships with the big multi national high tech Companies in network and in content.  '''Yasmin MERALI, Professor of University of Hull, UK''' This manifesto is connected with the ideals that I had as a founding member of our UniNet which was conceived as part of the FP7 ASSYST project. CS-DC has come a long way since its initial conception. The way I see it, there are three categories that have grown to emerge as our core activities- * Capacity building through education and training in Complex Systems Science * The application of Complex Systems Science to address global challenges * The advancement of Complex Systems Science through research and development. I believe this is a good time to link back to the inception of our UNITWIN which was in part inspired by considerations of issues at a human scale, and the desire to address the inequalities that divided the so-called developed and developing countries. This resonates strongly with the ambition of the Sustainable Development Goals (SDGs) we are currently grappling with. In the growth phase of the UNITWIN and CSDC we have been focused on extending the size of the network, and scaling up our educational offerings across the digital campus. In the next phase I believe we need to: # understand and leverage the diversity and distinctive capabilities and resources (e.g. indigenous knowledge) of the countries in our network to develop a healthy ecosystem, and # tailor the support that we provide to align with the diverse nature of their relational and social capital and their economic, political and environmental challenges and priorities with regard to the SDGs. I am concerned that if we do not explicitly design a social/ideational exchange mechanism that attends to these two imperatives, we will not have full, active participation of all member institutions, and the countries of the South that do not currently have champions in Europe will be marginalized. If elected I would champion a strategy of organizing ourselves following the Complex Adaptive Systems paradigm, as a hyper network with dynamically connected local clusters. In practical terms I would like to begin by establishing the local (country-based) clusters and establishing a discourse that would allow us to map the diverse profiles, challenges and aspirations for the different countries. This would then form the basis for the development of a mechanism for shaping the meaningful collaborative development of our three core activities to deliver advances that are globally co-ordinated and locally responsive. Personal Profile: I am Professor of Systems Thinking at the University of Hull and have served as Director of the Centre Systems Studies there. Prior to that I was Co-Director of the Doctoral Training Centre for Complex Systems Science at the University of Warwick. My research is transdisciplinary, focusing on the use of Complex Systems Science to enhance the resilience of socio-economic systems. I am an Expert advisor to the EU and I have significant experience of lecturing internationally as Visiting Professor in Asia, Europe and the USA. '''Céline ROZENBLAT: Professor, University of Lausanne - Institut de géographie et de durabilité (IGD), Switzerland''' I'm pleased to applied to become member of the CS-DC council. As founding member of CS-DC, my university, the university of Lausanne, is very engaged in Complex sciences. I would not only represent my university, but also social science as geographer and vice-president of the International Geographical Union and member of the International Science Council commission on Urban Health and Well being. I would act in the council in specific programs to develop the reality of the Digital Campus of the Complex systems. All these actions combine very ambitious interdisciplinary approaches, and in this perspective, we developed with CS-DC for 3 years the TIMES Flagship Territorial Intelligence For Multilevel Equity And Sustainability. It comprises four main programs: '''SIRE''': Socially Intelligence Roadmap Ecosystem '''POLE:''' Personalized Open Lifelong Education '''WOSI:''' Worldwide Open Smart Innovation '''WOSP:''' Worldwide Open Stochastic Prediction In this perspective a MOOC « Healthy Urban system » is now in development, basing the interdisciplinary approach on the CS-DC Road-Map grid. It seems very useful and relevant in this implementation stage. I would help to develop other programs in this perspective\[Ellipsis] '''André TINDANO, Director General of CARFS (African Center for Research and Training in Synecoculture)''' What motivates me to aspire to the position of member of the executive committee of CS DC is my long term participation in the promotion of sustainable development and my commitment to the sharing of knowledge and expertise. My research interests Sustainable agriculture, ecology, nutrition, life science. I have a strong experience in: * Administration and management of development projects and programs; * Accompaniment of associations and groups; * Technical capacity building (animation of training sessions and reflection workshops). * Action research; * Sociological, socio-economic and economic studies. * Development of development projects and programs; * Training of trainers * Results Based Management Training (RBM) * Monitoring and evaluation of development programs and projects; * Management of programs and development projects; * Institutional development and organizational strengthening; * Development and implementation of training / awareness / animation program; * Very good knowledge of participatory methods '''Guiou KOBAYASHI, Associate Professor at Federal University of ABC in São Paulo State, Brazil. ''' I worked with fault-tolerant computer systems for nuclear power plants and Metro signaling systems and recently my interests have evolved to resilience properties of Complex Systems. Traditionally, redundancy was the main feature for fault-tolerant and fail-safe systems, but the adaptability and the evolution of Complex Systems are the key elements for the resilience of these systems. How to characterize, design and implement these key elements in our future resilient systems? The Complex System - Digital Campus (CS-DC) is a way to create a world-wide community of researchers, philosophers and students to promote and discuss this kind of questions involving Complex Systems. For me, participating in its foundation was a great honor and I am very glad for the opportunity that I have had to contribute since 2012 in the consolidation of CS-DC. Through this manifest I am applying to be one of the members of the new CS-DC's Executive Committee. I would like to help just a little more to strengthen and structure this fantastic community through which I had the opportunity to meet important people with very interesting works that expanded my knowledge of Complex Systems. Although my University and my personal contribution for CS-DC are very limited and small, I hope to continue to work with this great team. '''Pierre COLLET, Professor of Computer Science, University of Strasbourg, France. Co-coordinator of the CS-DC UNESCO UniTwin''' The CS-DC initiated by Paul Bourgine, Jeffrey Johnson, Cyrille Bertelle and many others has been an extraordinary adventure a) to instantiate as a UNESCO UniTwin and b) to develop and run since it was enacted in July 2014. Many a night have been spent on designing its inner workings, so that it can deliver an effective affordance for the scientists who wish to develop the science and teaching of Complex Systems. Indeed, many projects seeded in the CS-DC have come to fruition, showing the enormous potential of this fertile environment not only for research, but also for teaching: the BBB rooms set up by the CS-DC have not only made it possible for the CS-DC to organize conferences, but have also shown their potential as remote teaching rooms in many Universities around the world. It has been an honour for me to be part of the development of the CS-DC since its beginning, but so much remains to be done! In this manifesto, I hereby express my strong desire to continue developing the CS-DC in these trying times, when the effects of the pandemics stretch thin the social links that our research and teaching communities need most. My objectives for this new mandate are not only to deliver a new world conference (originally planned in 2020 but unfortunately delayed due to the high toll imposed on us all, teachers and researchers alike, by COVID-19) but also continue on developing not only efficient complex computational ecosystems (cheap powerful PARSEC machines have been installed in several universities) but more specifically remote teaching environments based on complex systems, to mitigate the terrible impact of the pandemic on face to face education, within the POEM CS-DC flagship, on which Paul Bourgine and myself have been working for many years now.. '''Mariana C. BROENS, Professor - UNESP - BRAZIL.''' As members of the Executive Committee, our main challenge will be to raise, analyse and to discuss possible positive/negative ethical and political implications of the further development of the Complex Systems Science, and their application on studies of everyday social problems. In particular, We believe that the widespread use of complex system models and Big Data analytics can bring important questions about people's privacy, personal and corporate responsibility, widespread surveillance by public or private institutions, among many others, that should be deeply discussed in our community. Our contribution will be to raise and deepen these discussions from an interdisciplinary perspective. '''Cyrille Bertelle, Professor in Computer Sciences, University Le Havre, France, co-coordinator of the CS-DC UNESCO UniTwin''' I am a candidate for the CS-DC Executive Committee to represent the University of Le Havre Normandy, which is co-coordinator with the University of Strasbourg of the convention of recognition of the CS-DC as UniTwin by UNESCO. The University of Le Havre has made available to the community, resources and skills to provide digital collaborative tools for the organization of the Councils and the CS-DC'15 virtual conference. The objective I wish to take is to facilitate the involvement of member universities not only by their representatives on the council but by allowing researchers from these member institutions to join concrete and accessible actions. Co-responsible in the past of a master's degree on complex systems and then of the creation of the institute on complex systems in Normandie (France) in a multidisciplinary framework, I have participated in the setting up of the project labeled by the French national program of investments for the future and entitled "Smart Port City". The aim is to think about the future of territories in a sustainable development approach supported by new technologies and concerned about the environment and the well-being of their citizens. My research skills are focused on implementing the complexity of complex dynamic systems and networks, crossing behavioral scales from the interaction of human behaviors to the technical networks of the territory. The book "complex systems, smart territories and mobility" from the Springer's Understanding Complex Systems series, which will be published in January 2021 (https://www.springer.com/gp/book/9783030593018) illustrates the research coordination actions that I lead in these fields. '''Slimane Ben Miled, Senior Researcher at Pasteur Institute of Tunis, Professor at ENIT''' Our Tunisian consortium want to constitute a collaborative Research Training Programs to increase data science capacity related to health research in Africa by building trainings and enhancing institutional capacity at African academic institutions. The academy/project is based on 4 pillars to build a training ecosystem for Data and Engineering Science in health. # A platform of federated master’s programs with à la carte optional courses covering informatics/computer science, biomedical informatics, data science, statistics, and public health). Each program will keep its independence, with a mention to the academy label, and this platform will allow to enrich the training with optional modules, seminars, and courses in the partner institutions. New curricula will be created in relation to ethical issues. # Network of Doctoral programs and Executive programs # Platform of federated Business incubator and a career center offers training, support and funding for projects related to the project’s topic. This challenge is in perfect agreement with the Sustainable Development Goal 3 and the CS-DC flagship PHYSIOMES (Personalized Health phYSIcally, sOcially and Mentally for Each in their networkS). '''Masa Funabashi: researcher of open complex systems at Sony Computer Science Laboratories, Inc.''' I would like to contribute to the executive committee of CS-DC on the following two pillars: * Promote the FOOD (From smart agrOecOnomy to smart fooD) flagship project that aims to resolve the health-diet-environment trilemma through the promotion of sustainable food systems, in collaboration with the e-lab "human augmentation of ecosystems" members institution: Sony CSL, Synecoculture Association, CARFS, and those who wish to participate in CS-DC collaboration. * Construct a basic e-learning content on Synecoculture and ecological literacy as a part of CS-DC MOOCs and perform initial trials, principally in ECOWAS countries, through the Sony CSL-CARFS collaboration. Through the development of on-going activities in FOOD project and making synergy with other flagship projects, I would like to contribute CS-DC as a member of the executive committee and realize further extension toward the achievement of global sustainability goals such as SDGs.

László Barna Iantovics, Associate Professor at “George Emil Palade” University of Medicine, Pharmacy, Science and Technology of Targu Mures, Romania.''' With the present manifesto, I would like to candidate as a member of the CS-DC Executive Committee. I am the representative of “George Emil Palade” University of Medicine, Pharmacy, Science and Technology of Targu Mures from Romania in CS-DC. Some of my research and academic activities are related to the complex systems, including: publications, organization of conferences (e.g. Symposium on Understanding Intelligent and Complex Systems - UICS 2009; 1st Int. Conf. on Complexity and Intelligence of the Artificial and Natural Complex Systems Medical Applications of the Complex Systems. Biomedical Computing -CANS 2008; 1st Int. Conf. on Bio-Inspired Computational Methods Used for Difficult Problems Solving. Development of Intelligent and Complex Systems - BICS 2008), contribution to conference committees (e.g. Int. Conf. Emergent Proprieties in Natural and Artificial Complex Systems - EPNACS 2007; Workshop on Complex Systems and Self-organization Modeling -CoSSoM 2009), preparing journal special issues (e.g. Special Issue on Complexity in Sciences and Artificial Intelligence; Special Issue on Understanding Complex Systems), participating in journal’s editorial board (e.g. Complex Adaptive Systems Modeling -CASM, SpringerOpen), and contribution to research in projects and projects coordination (Social network of machines- SOON; Hybrid Medical Complex Systems -ComplexMediSys). I was the director of the center Advanced Computational Technologies – AdvCompTech in the frame of my university. At present, I am the director of the Center for Advanced Research in Information Technology from my university. I would like much deeper involve myself in the life and activities of the CS-DC community. My objectives: * To involve junior and senior researchers from my university in activities regarding research and education. To motivate universities and research institutes from my country to contribute to CS-DC. I consider also universities and research institutes with that I have collaboration in the past. * To PROPOSE the formation of a so-called doctoral and postdoctoral students group. In the case of doctoral and postdoctoral students probably in time more students would like to be involved in activities. In this framework, I suggest the organization yearly 3 times (from 4 to 4 months) workshops in that all the interested students could discuss, present their research and research in progress. With this occasion in the frame of workshops if there is interest could be established separate sessions with presentations also by B.Sc. and M.Sc. students. * To PROPOSE the strengthening of the following research direction with the general topic: intelligent complex systems and machine intelligence measuring. One of the subtopic by interest will be complex systems approaches in medicine and healthcare. To be accomplishable this subject I propose in a first step the formation of a group of interested persons, after then the establishment of the functionality of the group, for example: discussions when are subjects that should be discussed etc. ==Elected members to the Executive Committee & as (Deputy-)Presidents== '''Jeffrey JOHNSON, Professor of Complexity Science and Design, The Open University, UK''' I offer myself as a candidate both to be President and to the Executive Committee of The UNESCO UniTwin Complex Systems Digital Campus (CS-DC) so that I can help to drive it forward to achieve it goals. I am particularly committed to our educational efforts. I have made four MOOCs on the FutureLearn Platform for CS-DC ( https://www.futurelearn.com/partners/unesco-unitwin-complex-systems-digital-campus ): Global Systems Science (2015-16); Systems Thinking and Complexity (2017-18); First Steps in Data Science with Google Analytics (2018-19) and COVID-19 - Pandemics, Modelling and Policy (2020). CS-DC has a great opportunity to become the global university providing interdisciplinary education for a better world. I am also committed to our research mission with UNESCO towards the achieving the U.N. Sustainable Development Goals. My own research on representing the dynamics of complex multilevel systems is relevant to many of the research initiatives of CS-DC. I have extensive experience working within the complex systems community. I have run various coordination actions supporting research programmes funded by the European Commission, I am a founder member and past president of the Complex Systems Society, and I am Deputy-President of the CS-DC. I believe this experience will enable me to make a significant contribution the CS-DC over the next three years. '''Paul BOURGINE, present President of the UNESCO UniTwin CS-DC, Complex Systems Institute of Paris''' I offer myself as a candidate both to be President and to the Executive Committee of The UNESCO UniTwin Complex Systems Digital Campus (CS-DC). If elected, my main commitment is to create the conditions for a self-organized development of our UniTwin UNESCO CS-DC as autonomous communities of communities. This self-similar development will be the case both for the two main branches the UniTwin branch of our institutional members and the global eCampus branches of our individual scientific members: * for the UniTwin branch, the communities of communities are a territorial cascade with Smart Continents, smart countries, smart cities for their sustainable development according our flagship TIMES (Territorial Intelligence for Multilevel Equity and Sustainability). The roadmap is always the same, i.e. the cascade of the 17 Sustainable Development Goals and their 169 Targets: but their relative importance and coherence within this cascade vary from one territory to the others. The institutional members of the UniTwin branch have signed their agreement with the Cooperation Programme signed with UNESCO. In 2021, the CS-DC will ask for a cascade of agreements inside each institutional member, in order to have a "one for all" amplification within the other branch, the e-campus branch. * for the eCampus branch, the cascade of communities is along the refinement cascades when studying the theoretical and experimental challenges of complex systems. With Smart Continents'21, scientists are proposing their individual challenges that enact basic communities and communities of communities within the e-departments. In the "all for one" return, the roadmap of each university is the cascade of roadmaps within the eCampus where the University has at least one member. Furthermore each community can organise a monthly e-seminar or e-session in workshop as well as in CS-DC'21 for recorded advanced introductions. Such advanced introductions can be the basis for curriculum largely shared by the set of Universities having members in the community cascade of the curriculum. This "accelerator of knowledge and knowhow one for all and all for one" will first benefit to the student curriculum through the flagship POEM (Personalized Open Education for the Masses). This accelerator can be extended through the flagship POLE (Personalized Open Lifelong Education) for a lifelong education. This extended accelerator will be open to all, independently of previously achieved academic levels, respectful of the diversity of social and cultural environments and in a higher and higher inclusive way including refugees, migrants and primary people. genders, religions or ways of life. 9fzc7899wdd7ml9r8usjyuhxz95jnl8 2809679 2809678 2026-05-16T18:36:45Z ~2026-29396-85 3076712 /* Prof. Daniel Schertzer, Ecole nationale des ponts et chaussées */ 2809679 wikitext text/x-wiki ---- ----<nowiki>**</nowiki>Please ''login'' in Wikiversity and then use the ''<nowiki/>'edit''' button: your edition mode will be 'WYSIWYG'.

I am deeply committed to fostering the community of complex systems and am eager to contribute to the organisation of this talented group. I am particularly interested in the “living roadmap” of CS-DC, a unique feature that operates through two complementary strategies. Firstly, it addresses major transversal problems, and secondly, it focusses on classes of complex systems. This integrative systems framework is particularly pertinent to geosciences, which are increasingly integrating urban sciences, sustainability science, territorial planning, computational modelling, socio-ecological intelligence, and digital governance. Consequently, TIME—Territorial Intelligence for Multilevel Equity and Sustainability—is built on this integration process and is one of CS-DC’s principal flagship projects. The new chalenge with TIMES is to do it across scales, not only at an arbitrary scale. I possess extensive international experience as a scientist, mentor, leader, organiser, and editor, which I believe would be valuable assets to this role. Sincerely, Daniel Schertzer [https://hmco.enpc.fr/team-view/daniel-schertzer/ Short CV of Daniel Schertzer] '''Flavia Mori SARTI, Ph.D., Professor and Researcher, University of Sao Paulo, Brazil''' I present my interest in being candidate for the CS-DC Executive Committee to contribute to the dissemination of knowledge in complex systems at the local and global level. I am representative of the University of Sao Paulo (USP) at the CS-DC since 2012. I work with complex systems modeling since the creation of the Interdisciplinary Research Group of Complex Systems Modelling at the School of Arts, Sciences and Humanities (EACH-USP) in 2006. Our research group succesfully implemented the first interdisciplinary graduate program titled Master in Complex Systems Modeling in Brazil, in 2010. I have been participating in the program commission since 2010, and I was coordinator of the graduate program from 2010 to 2014. I have supervised 12 students in the program and two postdoctoral fellows, followed by publication of several book chapters and papers on complex systems applied to public policies, including models on tax evasion, health systems regulation, health insurance, food policy and nutrition programs, and complex networks on scientific collaboration and global food trade. I have been invited to present seminars and talks on complex systems applied to food systems, health economics, and public policy. My goals in the CS-DC Executive Committee include: * To disseminate the role of CS-DC in education and research on complex systems, especially in developing countries; * To support and to engage other research groups working with complex systems for participation in the CS-DC; * To contribute further with management and organization of CS-DC activities during the period of 2022-2024; * To continue supporting capacity building in complex systems through supervision and other academic activities; * To foster innovation, research and development strategies through complex systems applications in public policy and entrepreneurship. '''Alberto A. Rasia-Filho, MD, Ph.D, Professor and Researcher, Federal University of Health Sciences of Porto Alegre (UFCSPA) and Federal University of Rio Grande do Sul (UFRGS), Brazil''' Dear Councilors of the UNESCO CS-DC, It is an honor to submit my candidacy for the CS-DC Executive Committee for 2026. Please let me introduce myself as a Full Professor of Physiology (UFCSPA), Supervisor in the Biosciences (UFCSPA) and Neuroscience Graduate Programs (UFRGS), and a researcher on human neuronal morphology, dendritic spines, synaptic plasticity, and social/emotional neural networks (National Council for Scientific and Technological Development, Brazil). Professional Identifier/ORCID: 0000-0003-4623-5916. Currently, I am participating as head of the e-Team "Morphological Heterogeneity" in the UNESCO CS-DC, led by Prof. Enver Oruro Puma, Principal Investigator of the Morphodynamic Neuroscience and Behavior eLab CS-DC, and Prof. Grace E. Pardo, Scientific Research Institute, Continental University of Cusco, Peru. We integrate morphodynamics across different scales of brain organization and neural network functions in complex systems, considering neuronal morphology itself as an emergent level of organization. The structure of neural cells and their connectivity within the brain volume are morphodynamic features with interactions from cellular morphogenetic elements, the local cell neighborhood, and synaptic connections. In turn, the emergent functions of networks are organized around a series of conceptual, experimental, and computational foundations. These ideas were developed—and are now open to additional discussions—in the recent article from our group: “New Directions for Complex Systems in Contemporary Neuroscience: A Morphodynamic and Emergent Function Approach” (Research Topic: Theoretical and Computational Insights into Brain-Based Cognition/Frontiers in Computational Neuroscience). This represents an ongoing research line available for further collaborations in Complex Systems Science. I will be (1) committed to the Action Plan 2026 (and beyond) from the current 2026-31 Action Plan/Complex Systems Digital Campus UNESCO UniTwin, (2) working to integrate interdisciplinary approaches and eTeams, sharing knowledge and opportunities for complex systems education and research, as well as (3) contributing to country and continent engagement and representation in line with worldwide aims, (4) including the academic formation of young scientists. ----'''Norberto Garcia-Cairasco, BSc, MSc, PhD, Full Professor of Physiology-Neurophysiology, Ribeirão Preto School of Medicine, University of São Paulo (FMRP-USP), Ribeirão Preto, São Paulo State, Brazil.''' Dear Councilors of the UNESCO CS-DC, It is an honor for me to submit my candidacy for the CS-DC Executive Committee for 2026. Please, let me introduce myself as a Full Professor of Physiology-Neurophysiology, Ribeirão Preto School of Medicine, University of São Paulo (FMRP-USP), Ribeirão Preto, São Paulo State, Brazil. At FMRP-USP, I am Supervisor (Master and PhD) at both Graduate Programs in Physiology and Neurology/Neuroscience & Neuropsychiatry. I have been the Founder and the Director for almost 40 years of the Neurophysiology and Experimental Neuroethology Laboratory, where we conduct research in the characterization of epilepsies and associated neuropsychiatric comorbidities, using behavioral, electrophysiological, cellular, molecular and computational integrated tools, in both experimental and collaborative clinical settings.

Complex systems are involved in abnormal functioning and the refractoriness to pharmacological approaches of epileptogenic neural circuits, with additional multilevel complexity derived from associated, usually neuropsychiatric comorbidities. We, indeed, propose that the morphodynamics of neurons and glia in neural circuits can be studied as an initial step toward understanding proper wiring and stable properties, including neurotransmitters, neuromodulators, receptors, and intracellular signal transduction components, as well as plastic features, environmental stimuli, attention, and learning.

Starting part of this great adventure has changed my academic and personal life: thanks to the UniTwin, I have changed my research from stochastic optimisation, artificial evolution and AI in general to complex systems and epistemology. Participating in this UniTwin allowed me to make new contacts and start incredible projects that I could not have imagined before. It has even changed my life, as I am now living in Chile, having been recruited by ITISB, an institute founded by Carla Taramasco, the CS-DC representative for South America.

I would be interested in strengthening the relationship between CS-DC and CSS, as well as other organizations. ==Elected members to the Executive Committee for 2021 == '''Carlos J. BARRIOS H., PhD., Professor, Bucaramanga, Colombia ''' I write to express my interest to candidacy to be part of the CS-DC Executive Committee. I'm very motivated to develop actions to strengthen digital ecosystem supporting research and education proposals of our CS-DC Council. Among these years participating in the CS-DC group, I can see different ways to leverage the impact and the development of our actions with computational strategies, and now, I want to be part of the leadership council joined mutual visions. My experience leading the Advanced Computing System for Latin America and Caribbean (SCALAC : http://scalac.redclara.net ) and as member of other leadership boards in international projects (mainly between Europe and Latin America) supports my candidature. (linkedin.com/in/carlosjaimebh) Also, my role as professor, director and researcher contributes to build the common vision of the CS-DC Council and the leadership of the CS- DC Executive Committee. '''Mina TEICHER, Professor of Bar-Ilan University, Israël''' I submit my candidacy to the Executive Committee of the CS Digital Campus. If elected I will work towards our following needs, using my past experience in Professional international societies, universities managements and the data industry :  * We need in the near future to build an optimal and effective agreement with the Complex System Society. * We need to build a business  plan for fund raising. * We need to build a modular budget for 2021. * We need to build a strategy for geographically extension.  * We need to build a strategy for thematic  extension.  * We need to build partnerships with the big multi national high tech Companies in network and in content.  '''Yasmin MERALI, Professor of University of Hull, UK''' This manifesto is connected with the ideals that I had as a founding member of our UniNet which was conceived as part of the FP7 ASSYST project. CS-DC has come a long way since its initial conception. The way I see it, there are three categories that have grown to emerge as our core activities- * Capacity building through education and training in Complex Systems Science * The application of Complex Systems Science to address global challenges * The advancement of Complex Systems Science through research and development. I believe this is a good time to link back to the inception of our UNITWIN which was in part inspired by considerations of issues at a human scale, and the desire to address the inequalities that divided the so-called developed and developing countries. This resonates strongly with the ambition of the Sustainable Development Goals (SDGs) we are currently grappling with. In the growth phase of the UNITWIN and CSDC we have been focused on extending the size of the network, and scaling up our educational offerings across the digital campus. In the next phase I believe we need to: # understand and leverage the diversity and distinctive capabilities and resources (e.g. indigenous knowledge) of the countries in our network to develop a healthy ecosystem, and # tailor the support that we provide to align with the diverse nature of their relational and social capital and their economic, political and environmental challenges and priorities with regard to the SDGs. I am concerned that if we do not explicitly design a social/ideational exchange mechanism that attends to these two imperatives, we will not have full, active participation of all member institutions, and the countries of the South that do not currently have champions in Europe will be marginalized. If elected I would champion a strategy of organizing ourselves following the Complex Adaptive Systems paradigm, as a hyper network with dynamically connected local clusters. In practical terms I would like to begin by establishing the local (country-based) clusters and establishing a discourse that would allow us to map the diverse profiles, challenges and aspirations for the different countries. This would then form the basis for the development of a mechanism for shaping the meaningful collaborative development of our three core activities to deliver advances that are globally co-ordinated and locally responsive. Personal Profile: I am Professor of Systems Thinking at the University of Hull and have served as Director of the Centre Systems Studies there. Prior to that I was Co-Director of the Doctoral Training Centre for Complex Systems Science at the University of Warwick. My research is transdisciplinary, focusing on the use of Complex Systems Science to enhance the resilience of socio-economic systems. I am an Expert advisor to the EU and I have significant experience of lecturing internationally as Visiting Professor in Asia, Europe and the USA. '''Céline ROZENBLAT: Professor, University of Lausanne - Institut de géographie et de durabilité (IGD), Switzerland''' I'm pleased to applied to become member of the CS-DC council. As founding member of CS-DC, my university, the university of Lausanne, is very engaged in Complex sciences. I would not only represent my university, but also social science as geographer and vice-president of the International Geographical Union and member of the International Science Council commission on Urban Health and Well being. I would act in the council in specific programs to develop the reality of the Digital Campus of the Complex systems. All these actions combine very ambitious interdisciplinary approaches, and in this perspective, we developed with CS-DC for 3 years the TIMES Flagship Territorial Intelligence For Multilevel Equity And Sustainability. It comprises four main programs: '''SIRE''': Socially Intelligence Roadmap Ecosystem '''POLE:''' Personalized Open Lifelong Education '''WOSI:''' Worldwide Open Smart Innovation '''WOSP:''' Worldwide Open Stochastic Prediction In this perspective a MOOC « Healthy Urban system » is now in development, basing the interdisciplinary approach on the CS-DC Road-Map grid. It seems very useful and relevant in this implementation stage. I would help to develop other programs in this perspective\[Ellipsis] '''André TINDANO, Director General of CARFS (African Center for Research and Training in Synecoculture)''' What motivates me to aspire to the position of member of the executive committee of CS DC is my long term participation in the promotion of sustainable development and my commitment to the sharing of knowledge and expertise. My research interests Sustainable agriculture, ecology, nutrition, life science. I have a strong experience in: * Administration and management of development projects and programs; * Accompaniment of associations and groups; * Technical capacity building (animation of training sessions and reflection workshops). * Action research; * Sociological, socio-economic and economic studies. * Development of development projects and programs; * Training of trainers * Results Based Management Training (RBM) * Monitoring and evaluation of development programs and projects; * Management of programs and development projects; * Institutional development and organizational strengthening; * Development and implementation of training / awareness / animation program; * Very good knowledge of participatory methods '''Guiou KOBAYASHI, Associate Professor at Federal University of ABC in São Paulo State, Brazil. ''' I worked with fault-tolerant computer systems for nuclear power plants and Metro signaling systems and recently my interests have evolved to resilience properties of Complex Systems. Traditionally, redundancy was the main feature for fault-tolerant and fail-safe systems, but the adaptability and the evolution of Complex Systems are the key elements for the resilience of these systems. How to characterize, design and implement these key elements in our future resilient systems? The Complex System - Digital Campus (CS-DC) is a way to create a world-wide community of researchers, philosophers and students to promote and discuss this kind of questions involving Complex Systems. For me, participating in its foundation was a great honor and I am very glad for the opportunity that I have had to contribute since 2012 in the consolidation of CS-DC. Through this manifest I am applying to be one of the members of the new CS-DC's Executive Committee. I would like to help just a little more to strengthen and structure this fantastic community through which I had the opportunity to meet important people with very interesting works that expanded my knowledge of Complex Systems. Although my University and my personal contribution for CS-DC are very limited and small, I hope to continue to work with this great team. '''Pierre COLLET, Professor of Computer Science, University of Strasbourg, France. Co-coordinator of the CS-DC UNESCO UniTwin''' The CS-DC initiated by Paul Bourgine, Jeffrey Johnson, Cyrille Bertelle and many others has been an extraordinary adventure a) to instantiate as a UNESCO UniTwin and b) to develop and run since it was enacted in July 2014. Many a night have been spent on designing its inner workings, so that it can deliver an effective affordance for the scientists who wish to develop the science and teaching of Complex Systems. Indeed, many projects seeded in the CS-DC have come to fruition, showing the enormous potential of this fertile environment not only for research, but also for teaching: the BBB rooms set up by the CS-DC have not only made it possible for the CS-DC to organize conferences, but have also shown their potential as remote teaching rooms in many Universities around the world. It has been an honour for me to be part of the development of the CS-DC since its beginning, but so much remains to be done! In this manifesto, I hereby express my strong desire to continue developing the CS-DC in these trying times, when the effects of the pandemics stretch thin the social links that our research and teaching communities need most. My objectives for this new mandate are not only to deliver a new world conference (originally planned in 2020 but unfortunately delayed due to the high toll imposed on us all, teachers and researchers alike, by COVID-19) but also continue on developing not only efficient complex computational ecosystems (cheap powerful PARSEC machines have been installed in several universities) but more specifically remote teaching environments based on complex systems, to mitigate the terrible impact of the pandemic on face to face education, within the POEM CS-DC flagship, on which Paul Bourgine and myself have been working for many years now.. '''Mariana C. BROENS, Professor - UNESP - BRAZIL.''' As members of the Executive Committee, our main challenge will be to raise, analyse and to discuss possible positive/negative ethical and political implications of the further development of the Complex Systems Science, and their application on studies of everyday social problems. In particular, We believe that the widespread use of complex system models and Big Data analytics can bring important questions about people's privacy, personal and corporate responsibility, widespread surveillance by public or private institutions, among many others, that should be deeply discussed in our community. Our contribution will be to raise and deepen these discussions from an interdisciplinary perspective. '''Cyrille Bertelle, Professor in Computer Sciences, University Le Havre, France, co-coordinator of the CS-DC UNESCO UniTwin''' I am a candidate for the CS-DC Executive Committee to represent the University of Le Havre Normandy, which is co-coordinator with the University of Strasbourg of the convention of recognition of the CS-DC as UniTwin by UNESCO. The University of Le Havre has made available to the community, resources and skills to provide digital collaborative tools for the organization of the Councils and the CS-DC'15 virtual conference. The objective I wish to take is to facilitate the involvement of member universities not only by their representatives on the council but by allowing researchers from these member institutions to join concrete and accessible actions. Co-responsible in the past of a master's degree on complex systems and then of the creation of the institute on complex systems in Normandie (France) in a multidisciplinary framework, I have participated in the setting up of the project labeled by the French national program of investments for the future and entitled "Smart Port City". The aim is to think about the future of territories in a sustainable development approach supported by new technologies and concerned about the environment and the well-being of their citizens. My research skills are focused on implementing the complexity of complex dynamic systems and networks, crossing behavioral scales from the interaction of human behaviors to the technical networks of the territory. The book "complex systems, smart territories and mobility" from the Springer's Understanding Complex Systems series, which will be published in January 2021 (https://www.springer.com/gp/book/9783030593018) illustrates the research coordination actions that I lead in these fields. '''Slimane Ben Miled, Senior Researcher at Pasteur Institute of Tunis, Professor at ENIT''' Our Tunisian consortium want to constitute a collaborative Research Training Programs to increase data science capacity related to health research in Africa by building trainings and enhancing institutional capacity at African academic institutions.

I have made four MOOCs on the FutureLearn Platform for CS-DC ( https://www.futurelearn.com/partners/unesco-unitwin-complex-systems-digital-campus ): Global Systems Science (2015-16); Systems Thinking and Complexity (2017-18); First Steps in Data Science with Google Analytics (2018-19) and COVID-19 - Pandemics, Modelling and Policy (2020). CS-DC has a great opportunity to become the global university providing interdisciplinary education for a better world. I am also committed to our research mission with UNESCO towards the achieving the U.N. Sustainable Development Goals. My own research on representing the dynamics of complex multilevel systems is relevant to many of the research initiatives of CS-DC. I have extensive experience working within the complex systems community. I have run various coordination actions supporting research programmes funded by the European Commission, I am a founder member and past president of the Complex Systems Society, and I am Deputy-President of the CS-DC. I believe this experience will enable me to make a significant contribution the CS-DC over the next three years. '''Paul BOURGINE, present President of the UNESCO UniTwin CS-DC, Complex Systems Institute of Paris''' I offer myself as a candidate both to be President and to the Executive Committee of The UNESCO UniTwin Complex Systems Digital Campus (CS-DC). If elected, my main commitment is to create the conditions for a self-organized development of our UniTwin UNESCO CS-DC as autonomous communities of communities. This self-similar development will be the case both for the two main branches the UniTwin branch of our institutional members and the global eCampus branches of our individual scientific members: * for the UniTwin branch, the communities of communities are a territorial cascade with Smart Continents, smart countries, smart cities for their sustainable development according our flagship TIMES (Territorial Intelligence for Multilevel Equity and Sustainability). The roadmap is always the same, i.e. the cascade of the 17 Sustainable Development Goals and their 169 Targets: but their relative importance and coherence within this cascade vary from one territory to the others. The institutional members of the UniTwin branch have signed their agreement with the Cooperation Programme signed with UNESCO. In 2021, the CS-DC will ask for a cascade of agreements inside each institutional member, in order to have a "one for all" amplification within the other branch, the e-campus branch. * for the eCampus branch, the cascade of communities is along the refinement cascades when studying the theoretical and experimental challenges of complex systems. With Smart Continents'21, scientists are proposing their individual challenges that enact basic communities and communities of communities within the e-departments. In the "all for one" return, the roadmap of each university is the cascade of roadmaps within the eCampus where the University has at least one member. Furthermore each community can organise a monthly e-seminar or e-session in workshop as well as in CS-DC'21 for recorded advanced introductions. Such advanced introductions can be the basis for curriculum largely shared by the set of Universities having members in the community cascade of the curriculum. This "accelerator of knowledge and knowhow one for all and all for one" will first benefit to the student curriculum through the flagship POEM (Personalized Open Education for the Masses). This accelerator can be extended through the flagship POLE (Personalized Open Lifelong Education) for a lifelong education. This extended accelerator will be open to all, independently of previously achieved academic levels, respectful of the diversity of social and cultural environments and in a higher and higher inclusive way including refugees, migrants and primary people. genders, religions or ways of life. h1xotbrr6n72gtmrkohhm9nleyyndkd 2809680 2809679 2026-05-16T18:47:19Z ~2026-29396-85 3076712 /* Prof. Daniel Schertzer, Ecole nationale des ponts et chaussées */ 2809680 wikitext text/x-wiki ---- ----<nowiki>**</nowiki>Please ''login'' in Wikiversity and then use the ''<nowiki/>'edit''' button: your edition mode will be 'WYSIWYG'.

I am deeply committed to fostering the community of complex systems and am eager to contribute to the organisation of this talented group. I am particularly interested in the “living roadmap” of CS-DC, a unique feature that operates through two complementary strategies. Firstly, it addresses major transversal problems, and secondly, it focusses on classes of complex systems. This integrative systems framework is particularly pertinent to geosciences, which are increasingly integrating urban sciences, sustainability science, territorial planning, computational modelling, socio-ecological intelligence, and digital governance. Consequently, TIMES—Territorial Intelligence for Multilevel Equity and Sustainability—is built on this integration process and is one of CS-DC’s principal flagship projects. The new chalenge with TIMES is to do it across scales, not only at an arbitrary scale. I possess extensive international experience as a scientist, mentor, leader, organiser, and editor, which I believe would be valuable assets to this role. Sincerely, Daniel Schertzer [https://hmco.enpc.fr/team-view/daniel-schertzer/ Short CV of Daniel Schertzer] '''Flavia Mori SARTI, Ph.D., Professor and Researcher, University of Sao Paulo, Brazil''' I present my interest in being candidate for the CS-DC Executive Committee to contribute to the dissemination of knowledge in complex systems at the local and global level. I am representative of the University of Sao Paulo (USP) at the CS-DC since 2012. I work with complex systems modeling since the creation of the Interdisciplinary Research Group of Complex Systems Modelling at the School of Arts, Sciences and Humanities (EACH-USP) in 2006. Our research group succesfully implemented the first interdisciplinary graduate program titled Master in Complex Systems Modeling in Brazil, in 2010. I have been participating in the program commission since 2010, and I was coordinator of the graduate program from 2010 to 2014. I have supervised 12 students in the program and two postdoctoral fellows, followed by publication of several book chapters and papers on complex systems applied to public policies, including models on tax evasion, health systems regulation, health insurance, food policy and nutrition programs, and complex networks on scientific collaboration and global food trade. I have been invited to present seminars and talks on complex systems applied to food systems, health economics, and public policy. My goals in the CS-DC Executive Committee include: * To disseminate the role of CS-DC in education and research on complex systems, especially in developing countries; * To support and to engage other research groups working with complex systems for participation in the CS-DC; * To contribute further with management and organization of CS-DC activities during the period of 2022-2024; * To continue supporting capacity building in complex systems through supervision and other academic activities; * To foster innovation, research and development strategies through complex systems applications in public policy and entrepreneurship. '''Alberto A. Rasia-Filho, MD, Ph.D, Professor and Researcher, Federal University of Health Sciences of Porto Alegre (UFCSPA) and Federal University of Rio Grande do Sul (UFRGS), Brazil''' Dear Councilors of the UNESCO CS-DC, It is an honor to submit my candidacy for the CS-DC Executive Committee for 2026. Please let me introduce myself as a Full Professor of Physiology (UFCSPA), Supervisor in the Biosciences (UFCSPA) and Neuroscience Graduate Programs (UFRGS), and a researcher on human neuronal morphology, dendritic spines, synaptic plasticity, and social/emotional neural networks (National Council for Scientific and Technological Development, Brazil). Professional Identifier/ORCID: 0000-0003-4623-5916. Currently, I am participating as head of the e-Team "Morphological Heterogeneity" in the UNESCO CS-DC, led by Prof. Enver Oruro Puma, Principal Investigator of the Morphodynamic Neuroscience and Behavior eLab CS-DC, and Prof. Grace E. Pardo, Scientific Research Institute, Continental University of Cusco, Peru. We integrate morphodynamics across different scales of brain organization and neural network functions in complex systems, considering neuronal morphology itself as an emergent level of organization. The structure of neural cells and their connectivity within the brain volume are morphodynamic features with interactions from cellular morphogenetic elements, the local cell neighborhood, and synaptic connections. In turn, the emergent functions of networks are organized around a series of conceptual, experimental, and computational foundations. These ideas were developed—and are now open to additional discussions—in the recent article from our group: “New Directions for Complex Systems in Contemporary Neuroscience: A Morphodynamic and Emergent Function Approach” (Research Topic: Theoretical and Computational Insights into Brain-Based Cognition/Frontiers in Computational Neuroscience). This represents an ongoing research line available for further collaborations in Complex Systems Science. I will be (1) committed to the Action Plan 2026 (and beyond) from the current 2026-31 Action Plan/Complex Systems Digital Campus UNESCO UniTwin, (2) working to integrate interdisciplinary approaches and eTeams, sharing knowledge and opportunities for complex systems education and research, as well as (3) contributing to country and continent engagement and representation in line with worldwide aims, (4) including the academic formation of young scientists. ----'''Norberto Garcia-Cairasco, BSc, MSc, PhD, Full Professor of Physiology-Neurophysiology, Ribeirão Preto School of Medicine, University of São Paulo (FMRP-USP), Ribeirão Preto, São Paulo State, Brazil.''' Dear Councilors of the UNESCO CS-DC, It is an honor for me to submit my candidacy for the CS-DC Executive Committee for 2026. Please, let me introduce myself as a Full Professor of Physiology-Neurophysiology, Ribeirão Preto School of Medicine, University of São Paulo (FMRP-USP), Ribeirão Preto, São Paulo State, Brazil. At FMRP-USP, I am Supervisor (Master and PhD) at both Graduate Programs in Physiology and Neurology/Neuroscience & Neuropsychiatry. I have been the Founder and the Director for almost 40 years of the Neurophysiology and Experimental Neuroethology Laboratory, where we conduct research in the characterization of epilepsies and associated neuropsychiatric comorbidities, using behavioral, electrophysiological, cellular, molecular and computational integrated tools, in both experimental and collaborative clinical settings.

Complex systems are involved in abnormal functioning and the refractoriness to pharmacological approaches of epileptogenic neural circuits, with additional multilevel complexity derived from associated, usually neuropsychiatric comorbidities. We, indeed, propose that the morphodynamics of neurons and glia in neural circuits can be studied as an initial step toward understanding proper wiring and stable properties, including neurotransmitters, neuromodulators, receptors, and intracellular signal transduction components, as well as plastic features, environmental stimuli, attention, and learning. These ideas were developed, and are now open to additional discussions, in the recent article from our group: “New Directions for Complex Systems in Contemporary Neuroscience: A Morphodynamic and Emergent Function Approach” (Research Topic: Theoretical and Computational Insights into Brain-Based Cognition/Frontiers in Computational Neuroscience).

It would be a great honor for me if given the opportunity to contribute to the Executive Committee of UNESCO UniTwin CS-DC in the integration of Complex System research groups in the Latin American Region. For this, I propose the creation of two periodical activities: 1) A Special Lectures Series on Complex Systems UNESCO UniTwin CS-DC oriented to experts on Complex Systems, and 2) A Invited Advanced Lectures UNESCO UniTwin CS-DC oriented to experts who do not identify explicitly with complex systems '''Pierre Collet, full professor of Strasbourg University, on secondment to Universidad Andrés Bello, Instituto de Tecnología para la Innovación en Salud y Bienestar, Viña del Mar, Valparaiso, Chile'''. Since 2012, I have contributed to the elaboration of the CS-DC Unesco UniTwin together with Paul Bourigne, Jeffrey Johnson and many others, and I have been co-coordinator of the CS-DC UniTwin with Cyrille Bertelle since its creation in 2014. Starting part of this great adventure has changed my academic and personal life: thanks to the UniTwin, I have changed my research from stochastic optimisation, artificial evolution and AI in general to complex systems and epistemology. Participating in this UniTwin allowed me to make new contacts and start incredible projects that I could not have imagined before. It has even changed my life, as I am now living in Chile, having been recruited by ITISB, an institute founded by Carla Taramasco, the CS-DC representative for South America. Together with Paul and others, we would like to revive UniTwin by preparing another world conference inspired by the great success of [https://cs-dc-15.org CS-DC'15] and also develop flagship projects such as POEM (Personalised Open Education for the Masses) and the [https://en.wikiversity.org/wiki/Portal:Complex_Systems_Digital_Campus/E-Laboratory_on_complex_computational_ecosystems ECCE e-lab], which this year has welcomed a new very active [[Figures of Play/Les figures du Jeu e-team|Figures of Play]] that has started the [https://ludocorpus.org/ Ludocorpus] in France. As said before, this incredible UniTwin adventure always pays off for those who invest in it and in its great challenge: to develop the new science of complex systems through research and education. Through its projects, it contributes to making the world a better place to live in, despite the constant attacks on science coming from the most unlikely places. Science is the solution, not the problem, to many of the world's plagues. We must put our energy into developing it and defend it against all its detractors. That is why I am once again standing for election to the Executive Committee of this great CS-DC UniTwin. Modern science is Complex Systems science.

I am currently the Principal Investigator of a founded research project (with more than 30 research-collaborators) on a complex systems' approach to the concept of autonomy beyond its classical conception as an individual bounded property. As part of my university's goal of fostering international collaboration and opening up e-learning and research initiatives I would like to get more deeply involved on CS-DC with the following goals: * To desing the infrastructure, learning-experience, research-experience and content for distributed, open access and high-quality digital campus facilities. * To involve local agents (student, teachers, researchers and institutions) on the initiative of the network. * To foster collaboration, co-production and resource sharing between teaching and research facilities between priviledged richer countries and lower-income ones. In particular, but not exclusively, and for obvious reasons related to sharing the same language, to foster ''collaboration between European and Latin-american universities'', research initiatives and students through CS-DC. * To develop at least one ''prototype'' of a MSc level online course (and research network module) around complex cognitive systems that can serve as a model for the other fields of the network. * To develop a clear conceptual and communicative framework for CS-DC to be able to attract more participants, resources and broader attention and success as pioneering international initiative.

I was involved with CS-DC in its initial years in UNESCO's UniTwin, also representing UNAM. I have been editor-in-chief of Complexity Digest since 2007. I co-organized the Conference on Complex Systems in 2017. I am currently vice-president secretary of the Complex Systems Society (CSS). I am a strong proponent of open online learning. I managed to start a collaboration between UNAM and Coursera, which has led to more than a hundred MOOCs and millions of enrolled students. I would be interested in strengthening the relationship between CS-DC and CSS, as well as other organizations. ==Elected members to the Executive Committee for 2021 == '''Carlos J. BARRIOS H., PhD., Professor, Bucaramanga, Colombia ''' I write to express my interest to candidacy to be part of the CS-DC Executive Committee. I'm very motivated to develop actions to strengthen digital ecosystem supporting research and education proposals of our CS-DC Council. Among these years participating in the CS-DC group, I can see different ways to leverage the impact and the development of our actions with computational strategies, and now, I want to be part of the leadership council joined mutual visions. My experience leading the Advanced Computing System for Latin America and Caribbean (SCALAC : http://scalac.redclara.net ) and as member of other leadership boards in international projects (mainly between Europe and Latin America) supports my candidature. (linkedin.com/in/carlosjaimebh) Also, my role as professor, director and researcher contributes to build the common vision of the CS-DC Council and the leadership of the CS- DC Executive Committee. '''Mina TEICHER, Professor of Bar-Ilan University, Israël''' I submit my candidacy to the Executive Committee of the CS Digital Campus. If elected I will work towards our following needs, using my past experience in Professional international societies, universities managements and the data industry :  * We need in the near future to build an optimal and effective agreement with the Complex System Society. * We need to build a business  plan for fund raising. * We need to build a modular budget for 2021. * We need to build a strategy for geographically extension.  * We need to build a strategy for thematic  extension.  * We need to build partnerships with the big multi national high tech Companies in network and in content.  '''Yasmin MERALI, Professor of University of Hull, UK''' This manifesto is connected with the ideals that I had as a founding member of our UniNet which was conceived as part of the FP7 ASSYST project. CS-DC has come a long way since its initial conception. The way I see it, there are three categories that have grown to emerge as our core activities- * Capacity building through education and training in Complex Systems Science * The application of Complex Systems Science to address global challenges * The advancement of Complex Systems Science through research and development. I believe this is a good time to link back to the inception of our UNITWIN which was in part inspired by considerations of issues at a human scale, and the desire to address the inequalities that divided the so-called developed and developing countries. This resonates strongly with the ambition of the Sustainable Development Goals (SDGs) we are currently grappling with. In the growth phase of the UNITWIN and CSDC we have been focused on extending the size of the network, and scaling up our educational offerings across the digital campus. In the next phase I believe we need to: # understand and leverage the diversity and distinctive capabilities and resources (e.g. indigenous knowledge) of the countries in our network to develop a healthy ecosystem, and # tailor the support that we provide to align with the diverse nature of their relational and social capital and their economic, political and environmental challenges and priorities with regard to the SDGs. I am concerned that if we do not explicitly design a social/ideational exchange mechanism that attends to these two imperatives, we will not have full, active participation of all member institutions, and the countries of the South that do not currently have champions in Europe will be marginalized. If elected I would champion a strategy of organizing ourselves following the Complex Adaptive Systems paradigm, as a hyper network with dynamically connected local clusters. In practical terms I would like to begin by establishing the local (country-based) clusters and establishing a discourse that would allow us to map the diverse profiles, challenges and aspirations for the different countries. This would then form the basis for the development of a mechanism for shaping the meaningful collaborative development of our three core activities to deliver advances that are globally co-ordinated and locally responsive. Personal Profile: I am Professor of Systems Thinking at the University of Hull and have served as Director of the Centre Systems Studies there. Prior to that I was Co-Director of the Doctoral Training Centre for Complex Systems Science at the University of Warwick. My research is transdisciplinary, focusing on the use of Complex Systems Science to enhance the resilience of socio-economic systems. I am an Expert advisor to the EU and I have significant experience of lecturing internationally as Visiting Professor in Asia, Europe and the USA. '''Céline ROZENBLAT: Professor, University of Lausanne - Institut de géographie et de durabilité (IGD), Switzerland''' I'm pleased to applied to become member of the CS-DC council. As founding member of CS-DC, my university, the university of Lausanne, is very engaged in Complex sciences. I would not only represent my university, but also social science as geographer and vice-president of the International Geographical Union and member of the International Science Council commission on Urban Health and Well being. I would act in the council in specific programs to develop the reality of the Digital Campus of the Complex systems. All these actions combine very ambitious interdisciplinary approaches, and in this perspective, we developed with CS-DC for 3 years the TIMES Flagship Territorial Intelligence For Multilevel Equity And Sustainability. It comprises four main programs: '''SIRE''': Socially Intelligence Roadmap Ecosystem '''POLE:''' Personalized Open Lifelong Education '''WOSI:''' Worldwide Open Smart Innovation '''WOSP:''' Worldwide Open Stochastic Prediction In this perspective a MOOC « Healthy Urban system » is now in development, basing the interdisciplinary approach on the CS-DC Road-Map grid. It seems very useful and relevant in this implementation stage. I would help to develop other programs in this perspective\[Ellipsis] '''André TINDANO, Director General of CARFS (African Center for Research and Training in Synecoculture)''' What motivates me to aspire to the position of member of the executive committee of CS DC is my long term participation in the promotion of sustainable development and my commitment to the sharing of knowledge and expertise. My research interests Sustainable agriculture, ecology, nutrition, life science. I have a strong experience in: * Administration and management of development projects and programs; * Accompaniment of associations and groups; * Technical capacity building (animation of training sessions and reflection workshops). * Action research; * Sociological, socio-economic and economic studies. * Development of development projects and programs; * Training of trainers * Results Based Management Training (RBM) * Monitoring and evaluation of development programs and projects; * Management of programs and development projects; * Institutional development and organizational strengthening; * Development and implementation of training / awareness / animation program; * Very good knowledge of participatory methods '''Guiou KOBAYASHI, Associate Professor at Federal University of ABC in São Paulo State, Brazil. ''' I worked with fault-tolerant computer systems for nuclear power plants and Metro signaling systems and recently my interests have evolved to resilience properties of Complex Systems. Traditionally, redundancy was the main feature for fault-tolerant and fail-safe systems, but the adaptability and the evolution of Complex Systems are the key elements for the resilience of these systems. How to characterize, design and implement these key elements in our future resilient systems? The Complex System - Digital Campus (CS-DC) is a way to create a world-wide community of researchers, philosophers and students to promote and discuss this kind of questions involving Complex Systems. For me, participating in its foundation was a great honor and I am very glad for the opportunity that I have had to contribute since 2012 in the consolidation of CS-DC. Through this manifest I am applying to be one of the members of the new CS-DC's Executive Committee. I would like to help just a little more to strengthen and structure this fantastic community through which I had the opportunity to meet important people with very interesting works that expanded my knowledge of Complex Systems. Although my University and my personal contribution for CS-DC are very limited and small, I hope to continue to work with this great team. '''Pierre COLLET, Professor of Computer Science, University of Strasbourg, France. Co-coordinator of the CS-DC UNESCO UniTwin''' The CS-DC initiated by Paul Bourgine, Jeffrey Johnson, Cyrille Bertelle and many others has been an extraordinary adventure a) to instantiate as a UNESCO UniTwin and b) to develop and run since it was enacted in July 2014. Many a night have been spent on designing its inner workings, so that it can deliver an effective affordance for the scientists who wish to develop the science and teaching of Complex Systems. Indeed, many projects seeded in the CS-DC have come to fruition, showing the enormous potential of this fertile environment not only for research, but also for teaching: the BBB rooms set up by the CS-DC have not only made it possible for the CS-DC to organize conferences, but have also shown their potential as remote teaching rooms in many Universities around the world. It has been an honour for me to be part of the development of the CS-DC since its beginning, but so much remains to be done! In this manifesto, I hereby express my strong desire to continue developing the CS-DC in these trying times, when the effects of the pandemics stretch thin the social links that our research and teaching communities need most. My objectives for this new mandate are not only to deliver a new world conference (originally planned in 2020 but unfortunately delayed due to the high toll imposed on us all, teachers and researchers alike, by COVID-19) but also continue on developing not only efficient complex computational ecosystems (cheap powerful PARSEC machines have been installed in several universities) but more specifically remote teaching environments based on complex systems, to mitigate the terrible impact of the pandemic on face to face education, within the POEM CS-DC flagship, on which Paul Bourgine and myself have been working for many years now.. '''Mariana C. BROENS, Professor - UNESP - BRAZIL.''' As members of the Executive Committee, our main challenge will be to raise, analyse and to discuss possible positive/negative ethical and political implications of the further development of the Complex Systems Science, and their application on studies of everyday social problems. In particular, We believe that the widespread use of complex system models and Big Data analytics can bring important questions about people's privacy, personal and corporate responsibility, widespread surveillance by public or private institutions, among many others, that should be deeply discussed in our community. Our contribution will be to raise and deepen these discussions from an interdisciplinary perspective. '''Cyrille Bertelle, Professor in Computer Sciences, University Le Havre, France, co-coordinator of the CS-DC UNESCO UniTwin''' I am a candidate for the CS-DC Executive Committee to represent the University of Le Havre Normandy, which is co-coordinator with the University of Strasbourg of the convention of recognition of the CS-DC as UniTwin by UNESCO. The University of Le Havre has made available to the community, resources and skills to provide digital collaborative tools for the organization of the Councils and the CS-DC'15 virtual conference. The objective I wish to take is to facilitate the involvement of member universities not only by their representatives on the council but by allowing researchers from these member institutions to join concrete and accessible actions. Co-responsible in the past of a master's degree on complex systems and then of the creation of the institute on complex systems in Normandie (France) in a multidisciplinary framework, I have participated in the setting up of the project labeled by the French national program of investments for the future and entitled "Smart Port City". The aim is to think about the future of territories in a sustainable development approach supported by new technologies and concerned about the environment and the well-being of their citizens. My research skills are focused on implementing the complexity of complex dynamic systems and networks, crossing behavioral scales from the interaction of human behaviors to the technical networks of the territory. The book "complex systems, smart territories and mobility" from the Springer's Understanding Complex Systems series, which will be published in January 2021 (https://www.springer.com/gp/book/9783030593018) illustrates the research coordination actions that I lead in these fields. '''Slimane Ben Miled, Senior Researcher at Pasteur Institute of Tunis, Professor at ENIT''' Our Tunisian consortium want to constitute a collaborative Research Training Programs to increase data science capacity related to health research in Africa by building trainings and enhancing institutional capacity at African academic institutions. The academy/project is based on 4 pillars to build a training ecosystem for Data and Engineering Science in health. # A platform of federated master’s programs with à la carte optional courses covering informatics/computer science, biomedical informatics, data science, statistics, and public health). Each program will keep its independence, with a mention to the academy label, and this platform will allow to enrich the training with optional modules, seminars, and courses in the partner institutions. New curricula will be created in relation to ethical issues. # Network of Doctoral programs and Executive programs # Platform of federated Business incubator and a career center offers training, support and funding for projects related to the project’s topic. This challenge is in perfect agreement with the Sustainable Development Goal 3 and the CS-DC flagship PHYSIOMES (Personalized Health phYSIcally, sOcially and Mentally for Each in their networkS). '''Masa Funabashi: researcher of open complex systems at Sony Computer Science Laboratories, Inc.''' I would like to contribute to the executive committee of CS-DC on the following two pillars: * Promote the FOOD (From smart agrOecOnomy to smart fooD) flagship project that aims to resolve the health-diet-environment trilemma through the promotion of sustainable food systems, in collaboration with the e-lab "human augmentation of ecosystems" members institution: Sony CSL, Synecoculture Association, CARFS, and those who wish to participate in CS-DC collaboration. * Construct a basic e-learning content on Synecoculture and ecological literacy as a part of CS-DC MOOCs and perform initial trials, principally in ECOWAS countries, through the Sony CSL-CARFS collaboration. Through the development of on-going activities in FOOD project and making synergy with other flagship projects, I would like to contribute CS-DC as a member of the executive committee and realize further extension toward the achievement of global sustainability goals such as SDGs.

In case of invasion, it can affect the agriculture and pastures of about 25 countries including those of the poorest countries of the world, from Mauritania to India, while its best and most effective strategy of struggle is preventive struggle by targeting its first centers of gregarization which are very small in space and much better known today. In 2005, the costs of its struggle in the Sahel and North Africa amounted to half a billion dollars, with 8 million farmers and pastoralists affected in the Sahel. It also massively invaded Asia and Africa. 'East Africa in 2020.

László Barna Iantovics, Associate Professor at “George Emil Palade” University of Medicine, Pharmacy, Science and Technology of Targu Mures, Romania.''' With the present manifesto, I would like to candidate as a member of the CS-DC Executive Committee. I am the representative of “George Emil Palade” University of Medicine, Pharmacy, Science and Technology of Targu Mures from Romania in CS-DC. Some of my research and academic activities are related to the complex systems, including: publications, organization of conferences (e.g. Symposium on Understanding Intelligent and Complex Systems - UICS 2009; 1st Int. Conf. on Complexity and Intelligence of the Artificial and Natural Complex Systems Medical Applications of the Complex Systems. Biomedical Computing -CANS 2008; 1st Int.

I was the director of the center Advanced Computational Technologies – AdvCompTech in the frame of my university. At present, I am the director of the Center for Advanced Research in Information Technology from my university. I would like much deeper involve myself in the life and activities of the CS-DC community. My objectives: * To involve junior and senior researchers from my university in activities regarding research and education. To motivate universities and research institutes from my country to contribute to CS-DC. I consider also universities and research institutes with that I have collaboration in the past. * To PROPOSE the formation of a so-called doctoral and postdoctoral students group. In the case of doctoral and postdoctoral students probably in time more students would like to be involved in activities. In this framework, I suggest the organization yearly 3 times (from 4 to 4 months) workshops in that all the interested students could discuss, present their research and research in progress. With this occasion in the frame of workshops if there is interest could be established separate sessions with presentations also by B.Sc. and M.Sc. students. * To PROPOSE the strengthening of the following research direction with the general topic: intelligent complex systems and machine intelligence measuring. One of the subtopic by interest will be complex systems approaches in medicine and healthcare. To be accomplishable this subject I propose in a first step the formation of a group of interested persons, after then the establishment of the functionality of the group, for example: discussions when are subjects that should be discussed etc. ==Elected members to the Executive Committee & as (Deputy-)Presidents== '''Jeffrey JOHNSON, Professor of Complexity Science and Design, The Open University, UK''' I offer myself as a candidate both to be President and to the Executive Committee of The UNESCO UniTwin Complex Systems Digital Campus (CS-DC) so that I can help to drive it forward to achieve it goals. I am particularly committed to our educational efforts. I have made four MOOCs on the FutureLearn Platform for CS-DC ( https://www.futurelearn.com/partners/unesco-unitwin-complex-systems-digital-campus ): Global Systems Science (2015-16); Systems Thinking and Complexity (2017-18); First Steps in Data Science with Google Analytics (2018-19) and COVID-19 - Pandemics, Modelling and Policy (2020). CS-DC has a great opportunity to become the global university providing interdisciplinary education for a better world. I am also committed to our research mission with UNESCO towards the achieving the U.N. Sustainable Development Goals. My own research on representing the dynamics of complex multilevel systems is relevant to many of the research initiatives of CS-DC. I have extensive experience working within the complex systems community. I have run various coordination actions supporting research programmes funded by the European Commission, I am a founder member and past president of the Complex Systems Society, and I am Deputy-President of the CS-DC. I believe this experience will enable me to make a significant contribution the CS-DC over the next three years. '''Paul BOURGINE, present President of the UNESCO UniTwin CS-DC, Complex Systems Institute of Paris''' I offer myself as a candidate both to be President and to the Executive Committee of The UNESCO UniTwin Complex Systems Digital Campus (CS-DC). If elected, my main commitment is to create the conditions for a self-organized development of our UniTwin UNESCO CS-DC as autonomous communities of communities. This self-similar development will be the case both for the two main branches the UniTwin branch of our institutional members and the global eCampus branches of our individual scientific members: * for the UniTwin branch, the communities of communities are a territorial cascade with Smart Continents, smart countries, smart cities for their sustainable development according our flagship TIMES (Territorial Intelligence for Multilevel Equity and Sustainability). The roadmap is always the same, i.e. the cascade of the 17 Sustainable Development Goals and their 169 Targets: but their relative importance and coherence within this cascade vary from one territory to the others. The institutional members of the UniTwin branch have signed their agreement with the Cooperation Programme signed with UNESCO. In 2021, the CS-DC will ask for a cascade of agreements inside each institutional member, in order to have a "one for all" amplification within the other branch, the e-campus branch. * for the eCampus branch, the cascade of communities is along the refinement cascades when studying the theoretical and experimental challenges of complex systems. With Smart Continents'21, scientists are proposing their individual challenges that enact basic communities and communities of communities within the e-departments. In the "all for one" return, the roadmap of each university is the cascade of roadmaps within the eCampus where the University has at least one member. Furthermore each community can organise a monthly e-seminar or e-session in workshop as well as in CS-DC'21 for recorded advanced introductions. Such advanced introductions can be the basis for curriculum largely shared by the set of Universities having members in the community cascade of the curriculum. This "accelerator of knowledge and knowhow one for all and all for one" will first benefit to the student curriculum through the flagship POEM (Personalized Open Education for the Masses). This accelerator can be extended through the flagship POLE (Personalized Open Lifelong Education) for a lifelong education. This extended accelerator will be open to all, independently of previously achieved academic levels, respectful of the diversity of social and cultural environments and in a higher and higher inclusive way including refugees, migrants and primary people. genders, religions or ways of life. 82mxu2i2nksmawfe1nrlxrjn1vpgfll Vertical farming 0 273972 2809869 2433281 2026-05-17T05:05:33Z Amnsalem 3076913 Erased a word that was repeated 2809869 wikitext text/x-wiki This is a learning resource about vertical farming.

Physics is used to describe the world as we see it, predict the state of a given system in the future (and, inversely, reverse the process to predict what the starting conditions of a system were), and to ultimately create '''laws''' ("broad observations about how the universe behaves") and '''theories''' ("attempted explanations for the laws"). Physics is distinct from philosophy, in that physics and philosophy are used to solve separate classes of problems. A question a physicist might be well-suited to answer would be "If I toss a ball at a certain velocity and angle from the horizon, how far does the ball land away from me?", where a philosopher would be better suited to answer "What is the meaning of life?". Physics can be used to help aid philosophical discussion and vice versa, but very rarely do the fields overlap, simply because physics is a '''science'''. == Relationship with Mathematics == Mathematics is the best way to describe physics. The relationship between mathematics and physics is extremely close: the American physicist Richard Feynman famously described Calculus, a branch of mathematics devoted to the study of changing functions, as "The language God speaks". In learning physics, the more familiar one is with mathematics, the more fulfilling the study of physics will be to a student. One possible course of study for the mathematics required to do physics is: # '''Arithmetic''' (addition, subtraction, multiplication, and division is foundational to the other, more interesting branches of mathematics.) # '''Geometry''' (the study of shapes and symmetry is useful for simplifying and understanding more difficult problems.) # '''Algebra''' (rearranging equations for an unknown variable lets us make useful conclusions out of incomplete information.) # '''Trigonometry''' (The study of angles, circles, and triangles. Getting to here is an excellent starting point for high school physicists.) # '''Calculus''' (The mathematics of change. Despite being a highly fulfilling academic pursuit on its own, it gets us remarkably far in understanding the rest of physics.) # '''Linear Algebra''' (solving for unknowns in a ''system'' of equations leads to vectors, then launching into applications in further studies in mathematics.) # '''Differential equations''' (The real world changes as time goes on, differential equations lets us adjust our math for these changing conditions.) # '''Multi-dimensional calculus''' # '''Probability and Statistics''' == Problem-Solving Techniques == Physics is used to solve problems. Below are some techniques used by physicists (but sometimes applicable to non-physicists) to tackle problems: suppose we are trying to solve for the position and velocities of two billiard balls after their collision. * '''Try a simpler version of the problem'''. (Example: instead of trying to solve for the final velocities of the two billiard balls given any initial angles, could we first try to solve it in one dimension by assuming the balls are held on a single line? That way, we can be better prepared to solve the full problem later, given what we have learned about the problem before. We could also ignore factors like the balls slipping on the table, the angular momentum of the balls, friction with the table, ''et cetera''.) * '''Use the defining features of a problem.''' (Example: we know that billiard balls tend to bounce off each other, and never stick to one another. Can we use this to justify an assumption to make the math easier?) * '''List any equations that might be relevant.''' (Example: it appears that momentum and energy might be conserved, so let's start by writing those two equations: momentum is the product of mass and velocity, and kinetic energy is mass times half of velocity squared: <math>p = mv ; T = \frac{mv^2}{2}</math> * '''Seek Symmetry.''' (Example: if you are trying to find how two billiard balls will collide, can you ignore motion along any direction by assuming the balls won't move in the z-direction ("flying off the table")?) * '''Compute something (anything) to build intuition.''' (Example: instead of trying to find how the starting and ending momentum are related to one another, why don't we try just finding the total momentum? That might help.) * '''Run simulations (if possible) to build intuition.''' (Example: although creating a simulation of how the two billiard balls might be impractical without some coding experience, the situation is simple enough to just do experimentally. If you have two billiard balls, bouncy balls, or even marbles lying around, why don't you just try it?) * '''Draw pictures.''' (Example: what does the situation we've described even look like?) == Modern branches of physics == There are two main theories, general relativity and quantum mechanics. General relativity deals with why things fall and quantum mechanics deal with everything else. There is also a thing called special relativity and it can be summarized like this: When things move faster, they become heavier, shorter and experience time slower, all by a factor of <math>\frac{1}{\sqrt{1-\frac{v^2}{c^2}}}</math>. Energy is just that factor*mass*(speed of light)^2, and momentum is that factor*mass*speed. === General Relativity === General relativity says that things fall because the earth curves the space (and time) around it. To see why this works, get a globe. Place your left index finger where the prime meridian and the equator meet. Place your right index finger 90 degrees from your left one, keeping both on the equator. Then slowly run both hands in a straight line, heading north (running your finger represents moving time). Notice how they both collide. The formula for how space curves is very complicated, but there is a simpler formula that predicts similar things, as long as you're nowhere near a black hole. Otherwise, you should be more focused on getting away from the black hole, if anything. The simpler, not perfectly accurate formula is here: <math>a=\frac{Gm}{r^2}</math> where a is the acceleration required to keep object at a constant distance r from a mass m. === Quantum mechanics === See also: [[Quantum mechanics/Introduction]] Quantum mechanics describe three main forces, electromagnetism, the strong and weak nuclear force. It also suggests that the position and momentum of everything is a probability cloud, that is, that I am currently in multiple places at once and that I could move at different speeds at once. This also implies that I can change speed sporadically as the uncertainty can mean that my speed may be different in the future. Though, before you call BS on this one though, most objects (and living things) are large enough such that there is a lot of certainty about where I am and how fast I'm moving (as per <math>\Delta p \Delta s\geq\hbar</math>). The latter implies inertia, a phenomenon in which large things conserve momentum. There is also another formula: <math>\Delta E \Delta t \geq \hbar</math>: uncertainty in energy times uncertainty in time is always above some value. This means that in theory, a very high energy or high enough mass could just poof into existence like magic, but it must be gone in a short amount of time such that we can't notice it in all of the noise. This means that energy and mass are conserved, for all intents and purposes. === Context for the rest of the section: === [[Chemical Sciences]] === Electromagnetism === This word is used a lot to talk about nonsense, but trust me, quantum mechanics is not pseudoscience. Electromagnetism the force that attracts or repels two charged objects, like the electrons on my hand and those on the keyboard, allowing me to press the keys on my keyboard. It is explained by the use of photons, particles which are also responsible for sight. So when I push on one of the keys of my keyboard, the electrons in my finger and those on the keyboard exchange photons, forcing the key to go down. Thus, electromagnetism is responsible for so called 'contact forces'. === Strong Nuclear Force === The strong nuclear force is the force keeping the nuclei inside atoms together. As protons are repelled by each other, due to having the same charge, another force and new particles, one of which is the neutron (the neutron contributes to the strong nuclear force, but not to the electromagnetic repulsion) and the other is the gluon, which carries the force. So in a nucleus, the protons and neutrons exchange gluons, keeping it together, though, sometimes, it just isn't enough... === Weak Nuclear Force === The weak nuclear force is a mechanism for nuclei which don't want to exist (they're called radioactive nuclei) to not exist. Sure, sometimes they might just break apart, but other times, they use this mechanism, called beta decay. When a nucleus has had enough of life, a neutron might decide to turn into a proton and emit an electron (which will go into orbit around the atom) and a new particle called a neutrino. The weak nuclear force is exchanged by the W and Z bosons. == Test == 1. Debunk the following flat earth arguments : 1a. Why doesn't everything fall off if the earth is spinning? : 1b. Water curves on the round earth. Doesn't water always maintain it's own level? : 1c. Gravity doesn't exist, therefore it can't make the earth round. Everything falls because denser things are attracted to the earth, displacing :: lighter objects. 2. Debunk the following anti-5G argument: Electromagnetic radiation, which is given by 5G, is inherently harmful. 3. Why don't nuclei fly apart? 4. How does beta decay work? 5. What do fast-moving objects do? == Test answers == 1a. Gravity keeps things onto the earth, despite the fact that earth is spinning. This is a valid point, as inertia is a thing and large objects will maintain their momentum imparted by the earth, and will fly off into space. But gravity exists, fortunately. 1b. Water does not maintain it's own level. Water molecules are not magically immune to the curvature of space, explaining how water can curve around the earth. 1c. Your new model doesn't work. For example, place some lead on top of a bag of feathers. The lead doesn't pass through the feathers now, does it? 2. Electromagnetic force is transmitted by photons, aka, light. Therefore, it's rational to assume that 'electromagnetic radiation' means light. Light is not inherently harmful. 3. Nuclei don't fly apart due to the strong nuclear force. 4. Beta decay involves a neutron splitting apart due to the weak nuclear force. 5. Fast moving objects become heavier, shorter and experience time more slowly.

In the diagram the figure defined by solid black lines is a cube. Width = depth = height = 2. The length of one side is 2 units. The surface area of one side <math>=\ height * depth</math> or <math>height * width</math> or <math>width * depth = 2 * 2</math> or <math>2^2</math> square units.

There have been considerable advances in knowledge about phenomenology, assessment, physiological correlates, and even some data about longitudinal course (Birmaher et al., 2009; Geller, Tillman, Bolhofner, & Zimerman, 2008); but at the same time there continues to be vigorous discussion about the appropriateness of the diagnostic label (Healy, 2006; Leibenluft, Charney, Towbin, Bhangoo, & Pine, 2003), and the implications in terms of treatment (Blader & Carlson, 2007; Moreno et al., 2007), extending from the popular press (Kluger & Song, 2002) to the deliberations about revision of the Diagnostic and Statistical Manual of the American Psychiatric Association ([http://www.dsm5.org/ www.dsm5.org]). In short, the objectives of the project are timely and informative. The presentation of findings in this closing report will closely follow the structure of the specific and secondary aims from the funded version of the project. The format will be a recapitulation of the aim, followed by a brief narrative and then extensive tables or figures as appendix material, with the numbering reinforcing the link to each aim. The overall goal of this project was to create a foundation for better defining and assessing bipolar disorders in pediatric populations. This submission consisted of two tightly interwoven studies. Together they will (a) establish a base rate for bipolar disorders in community mental health, and document the phenomenology of symptom presentation and associated characteristics, (b) evaluate the concordance between research and conventional diagnoses, (c) test the performance of instruments that have shown promise in a research mood disorders clinic when these are exported into a naturalistic community setting, (d) develop an abbreviated screening protocol optimized for use in community samples, and (e) prospectively cross-validate the use of the abbreviated screening protocol. '''A. Specific Aims:''' '''Aim #1: To develop and prospectively cross-validate a juvenile bipolar spectrum disorder (BPSD) screening protocol optimized for use in community settings with representative, ethnically diverse populations.''' ''Hypothesis 1: Measures that performed well in pilot data from a research setting will demonstrate statistically significant diagnostic efficiency when exported to a community setting.'' The R01 used a LEAD consensus conference (Spitzer, 1983) as a way of assigning final diagnoses, after completing a KSADS interview (Geller et al., 2001; Kaufman et al., 1997) with the youth and primary caregiver. The same rater teams completed diagnostic interviews at both the community mental health center (CMHC) and academic medical center (AMC) sites, eliminating differences in rater experience or training as a potential confound in generating diagnoses. The criterion diagnosis for the primary analyses of diagnostic efficiency was the presence or absence of a bipolar spectrum diagnosis. The bipolar criterion included bipolar I, bipolar II, cyclothymic disorder, and bipolar not otherwise specified (bipolar NOS), regardless of any potential other comorbid conditions. The inclusion of “spectrum” conditions such as cyclothymic disorder makes it harder for diagnostic efficiency to remain high, because these cases will have less clear cut symptom presentations, and they cannot have distinct manic episodes or else their diagnosis would “upgrade” to bipolar I, by definition. As a result, diagnostic sensitivity would be expected to be lower, as more “bipolar criterion” cases would be likely to earn only moderately elevated scores on instruments attempting to detect them. Similarly, the comparison group contains all other cases presenting to the clinic. There were no exclusion criteria at the community mental health site, other than an inability to complete the interview in spoken English. This stands in marked contrast to the sampling strategy in prior phenomenologically oriented studies, where the comparison groups were selected to include healthy controls, or cases with attention-deficit/hyperactivity disorder without a comorbid mood disorder. Although these more homogeneous and distilled groups provide valuable comparators for phenomenology or for neurocognitive studies, they are quite different in composition and functioning than clinically representative samples. The high rates of stress, mood, anxiety, attention problems, and aggressive behavior in a clinically representative sample were expected to increase scores on measures attempting to detect mania, creating more “false positives” and reducing the diagnostic specificity. Both expectations proved correct. Bipolar Spectrum presentations were far more common than bipolar I cases in community mental health, and the average scores on all bipolar screening measures tended to be slightly lower in the bipolar group in the CMHC setting, with large individual differences (and big standard deviations). Similarly, the average scores were higher in nonbipolar cases in the CMHC, reflecting the high degree of distress and complexity in these cases. These combined to lower the diagnostic efficiency of all instruments examined (see Table 1). Secondary analyses of the preliminary data submitted with this R01 proposal demonstrated that the effects of sample composition on the diagnostic efficiency performance of instruments could be marked (Youngstrom, Meyers, Youngstrom, Calabrese, & Findling, 2006). The performance observed in the present sample was lower than reported in the prior validation studies. The decrement ranged from small (e.g., area under the curve for the PGBI Hypomanic/Biphasic 28 item score changing from .78 in Youngstrom et al., 2004 to .77 in the present data) to moderate (AUROC of .86 for the 10 item PGBI mania scale in its development sample (Youngstrom, Frazier, Demeter, Calabrese, & Findling, 2008), down to a .79 in the present sample) and in some cases, substantial – such as the P-YMRS dropping to an AUROC of .67. The P-YMRS performance was sufficiently poor that it is clearly statistically inferior to all the other caregiver report measures examined, and we have stopped using it clinically as a result. The “CBCL Bipolar Profile” index (summing or averaging the Aggressive Behavior, Attention Problems, and Anxious/Depressed Scales from the CBCL) (Mick, Biederman, Pandina, & Faraone, 2003) distinguished the bipolar from nonbipolar cases significantly better than chance, but significantly less well than all the other mood scales (except for the PYMRS), AUROC = .67. Overall, it was encouraging that all of the caregiver-reported measures continued to demonstrate statistical validity, despite the changes in sample composition and demographics. '''Caregiver Report.''' Table 2 reports the percentage of maximum possible (POMP) (Cohen, Cohen, Aiken, & West, 1999) scores on all of the caregiver reported measures that specifically assess the mood symptoms of the youth, comparing scores for youths meeting full DSM-IV criteria for bipolar I (''n''=28) with youths meeting criteria for another bipolar spectrum disorder (e.g., bipolar II, cyclothymic disorder, or bipolar NOS; ''n''=116), unipolar depression or dysthymic disorder (''n''=221), ADHD or a disruptive behavior disorder without comorbid mood (''n''=353), or all other cases presenting to the clinic (''n''=72). Across all six measures investigated, the two bipolar groups were significantly more elevated than the other three non-bipolar groups, but the bipolar I group was never significantly different from the rest of the bipolar spectrum. Tables 3 and 4 report the same breakdowns for the CBCL broad band, clinical syndrome scales, and DSM-Oriented scales. Examination of the tables indicates that the differences are more moderate on non-mood oriented scales. '''Youth Self Report.''' Another way of measuring manic symptoms would be to rely on self report by the youth. This is consistent with how most of adult psychiatry conducts diagnostic screening or assessment. Analyses of the preliminary data for this grant (Youngstrom et al., 2004) suggested that youth report tends to discriminate bipolar from nonbipolar cases at better than chance rates, but significantly less well than parent report. This trend was also observed in an interim analysis of the data gathered under the auspices of this grant (Youngstrom et al., 2005), and it aligns with the effect sizes observed when comparing caregiver versus youth or teacher report about cases with bipolar disorder (Geller, Warner, Williams, & Zimerman, 1998; Hazell, Lewin, & Carr, 1999). The final analyses from this project continue to fit that pattern. As shown in Table 1, youth self report showed substantially lower AUROC values than did parent report. In the case of a self-report version of the YMRS, scores did not do better than chance at separating the bipolar spectrum cases, indicating a statistically “invalid” test (Kraemer, 1992). We hypothesize that there are two factors undermining the validity of self report about manic symptoms: One is that compromised insight is a feature of mania (Dell'Osso et al., 2002), and the other is that many of the symptoms of mania are things that would bother other people before they become subjectively noticeable to the person experiencing them. The adolescent with mania is not going to be the first person to notice when they are talking “too much,” or when their own mood seems irritable. Tables 5, 6, and 7 provide average scores on youth reports compared across diagnostic subgroups. '''Teacher Report.''' A third source of information this project examined was teacher report. Findings with the Achenbach Teacher Report Form (Achenbach & Rescorla, 2001) replicate prior work in three important ways: (a) youths with bipolar disorder tend to show significant elevations on multiple behavior problems in school settings (e.g., ''T''-scores higher than 50); (b) teacher-parent agreement was as good or higher with regard to bipolar spectrum cases (''r''=.38) versus nonbipolar cases (''r''=.30, both comparing favorably to meta-analyses and normative data about teacher-parent agreement); and (c) teacher report operated at near-chance levels in discriminating bipolar from nonbipolar cases (nonsignificant AUROCs in ROC analyses). A secondary aim of this project was to develop and test “second generation” mania rating scales that could be completed by teachers. Results indicated that it is difficult to measure manic symptoms using teacher report. Many items were difficult to rate, and teachers frequently skipped them. Reliability estimates were lower and factor structures often quite different in teacher report versus the corresponding caregiver or youth report on the same measure. AUROC values on teacher report were  consistently low and usually no better than chance at discriminating bipolar disorder from other cases (Youngstrom, Joseph, & Greene, 2008). Tables 8, 9, and 10 compare averages on teacher measures across diagnostic subgroups. Hypothesis 2: ''An abbreviated screening instrument can be developed on the basis of community sample data that will retain comparable levels of diagnostic efficiency versus a lengthier screening instrument when cross-validated in an independent, prospective sample.'' During the time that the grant was enrolling, there were several new measures developed and advertised for the assessment of bipolar disorder in youths. These included the parent version of the Mood Disorder Questionnaire (Hirschfeld et al., 2000), which performed better as a parent report instead of self report instrument (Wagner, Findling, Emslie, Gracious, & Reed, 2006; Youngstrom, et al., 2005); as well as the Child Mania Rating Scale (Henry, Pavuluri, Youngstrom, & Birmaher, 2008; Pavuluri, Henry, Devineni, Carbray, & Birmaher, 2006) and other instruments. The protocol included the PGBI, the P-MDQ, and added the CMRS when it became available. When the time came to recommend an instrument for validation as a general screener for bipolar disorder, the Mood Disorder Questionnaire had become a commercially distributed instrument. There were more data available and published on the PGBI than any other instrument except the CBCL, which the PGBI had outperformed in all direct comparisons for the purpose of detecting bipolar spectrum disorder. The combination of validity evidence and low cost led to the selection of a 10 item Mania Scale version of the PGBI (PGBI-10M; Youngstrom, Frazier, et al., 2008) as the tool of choice for cross-validation in a community mental health sample. The 10 item mania scale became a standard part of the intake for the last two years of the grant. It demonstrated excellent psychometric properties, with a Cronbach’s alpha of .90, a one month retest reliability of .62, and an Area Under the Curve of .78 for discriminating bipolar versus all other cases based on a diagnostic interview some weeks later, versus an AUROC of .80 for a concurrently administered version of the PGBI. '''Aim #2: To clarify the characteristic features of “subsyndromal” bipolar spectrum disorders, currently referred to as “Bipolar NOS” (Nottelmann et al., 2001), in both research and community settings.''' Hypothesis 3: Taxometric statistical procedures will identify a group of children and adolescents experiencing a categorically different pattern of manic and depressive symptoms than expressed by the rest of the participants. The taxometric statistical methods concentrated on the parent report measures, because these had demonstrated the largest effect sizes in the diagnostic efficiency analyses (i.e., largest AUROC values). Youth self report and teacher report often failed to perform better than chance when comparing groups based on DSM definitions. Although it is possible that other categories exist that would be associated with youth or teacher report, it is highly unlikely that existing measures would provide large effect sizes for sorting cases into previously unsuspected, atheoretical categories. The clinician-rated measures were disqualified for a different reason: Other simulation studies and investigations have found that clinician-rated instruments can create taxonic or continuous data, depending on how raters are trained or how expectations are framed. The emergence of a taxon using data drawn from the KSADS interviews thus would require cross-validation by an independent source of information (such as caregiver report on rating scales that were recused from the consensus diagnostic process). Thus caregiver report was the most likely and most independent source of information for taxometric analyses. Based on two methods, Maximum Eigenvalue (MAXEIG) and Mean Above Minus Below A Cut (MAMBAC), the parent report data about manic, hypomanic, and mixed symptoms in the youths conformed to a dimensional model. Table 11 presents the power analysis for the taxometric procedures, which ranged from “acceptable” (''d''=1.6) to high (''d''=2.7). See Figures 1 and 2 for the visual plots of the results, as well as simulations for categorical and dimensional solutions. We plan to conduct additional analyses using latent class and latent profile models to search for subgroups, but based on the present findings, we expect that a graded class model where cases are best distinguished by their underlying level of overall mania (similar to Krueger’s findings for other psychopathology constructs) (Krueger, Markon, Patrick, & Iacono, 2005) are likely to be the best fitting models. The dimensional results are also consistent with recently published analyses of adult epidemiological data on mania (Prisciandaro & Roberts, 2010). A dimensional model is also most consistent with emerging findings about the polygenic nature of bipolar disorder, with a large number of genes that each contribute small amounts of risk (WTCCC, 2007). Hypothesis 4: Bipolar spectrum disorders will be associated with the highest average level of impairment of any major diagnostic category in a community sample. Consistent with the hypothesis, both the bipolar I and other bipolar spectrum disorders were associated with the lowest level of average functioning, whether quantified as the Global Assessment of Functioning at the end of the KSADS interview, or using the “most severe past” or “highest level of functioning in the past year” Global Assessment Scale (CGAS; Shaffer et al., 1983) ratings. As was the case with the mood ratings (see Table 12A), the bipolar I cases were not significantly different from the rest of the bipolar spectrum on any of these measures of functioning. Table 12B summarizes means across diagnostic subgroups. More than 90% of cases with bipolar disorder reported impairment in more than one setting. Supplemental analyses found that when bipolar was comorbid with ADHD, it was not associated with an increase in the number of settings where the youth experienced impairment. The same pattern held with ODD compared to bipolar+ODD; see Tables 13 and 14 for details. '''Aim #3: To investigate developmental changes in symptom occurrence and presentation across the age-span from ages 5 to 17 years (including an examination of the validity of this diagnosis in terms of functional impairment and longitudinal course).''' Hypothesis 5: There will be identifiable continuity in the type and pattern of symptoms presented by youths meeting BPSD criteria across the agespan, although this may require the use of different assessment strategies at different ages. To examine age effects on symptom presentation, we grouped the sample into “prepubertal” (5 to 8 years), “peri-pubertal” (9 to 12 years), and Adolescent (13 to 18 years). When limiting the sample to youths identified as being on the bipolar spectrum per the LEAD diagnoses, there was evidence of significantly higher levels of depression in the peri-pubertal or adolescent groups than the pre-pubertal group, whether measured on the caregiver PGBI Depression scale (see Table 15), the KSADS Depression Rating Scale for past two weeks and worst lifetime, or the CDRS-R (trend) (Table 16). Findings were the opposite for interview-based ratings of mania in the past two weeks, with the adolescent group showing significantly lower ratings than the other two age-groups on the YMRS or KSADS Mania Rating Scale for the current episode. The “worst lifetime” mania ratings showed higher average scores in the older two groups, which makes sense given that these scores either matched the current episode or were higher if there was a more severe past episode. Age trends were not evident on parent report of manic symptoms. The general pattern of increasing depressive symptoms with puberty is consistent with a large body of research (Cyranowski, Frank, Young, & Shear, 2000; Kovacs, 1989). The tendency to see decreases in manic symptoms with age matches clinical observations by Kraepelin (1921, Figure 46, p. 169), and also is consistent with recent analyses of two large USA epidemiological data sets (Cicero et al., 2009). Further investigation is needed to investigate the extent to which these patterns might be influenced by developmental offset of ADHD, which can inflate scores on some symptoms and measures of mania more than others. A secondary set of analyses also investigated differences across age cohorts in the symptoms reported by the primary caregiver, using raw scores on the CBCL. We used raw scores because the standard scores are age-normed, eliminating age trends in behavior by design. Tables 17 and 18 present the averages and eta-squared effect sizes for the clinical syndrome scales and broad bands. The largest effects were lower levels of Aggressive Behavior and Social Problems in adolescence, and increasing levels of Withdrawn behavior in adolescence. Scores on the CBCL “Bipolar Profile” (now referred to as the “Emotional Dysregulation Profile”) also were significantly lower in adolescence. When examining the DSM-Oriented Scales, there were significantly lower averages on the Attention Problems and the Somatic Problems scales in adolescence (although the corresponding clinical syndrome scales, with broader item content, did not achieve statistical significance). No other differences achieved statistical significance. A set of secondary analyses are examining the possibility that responses to specific symptoms change developmentally. This more fine-grained investigation is using “Differential Item Functioning” (DIF) techniques developed in the psychometric literature. Analyses conducted so far have focused on parent reported scores, because they provide consistent methodology across the largest age range. DIF could take two forms, sometimes described as “uniform” and “nonuniform” DIF. Uniform DIF describes the situation when there are average differences in the item score between groups (in this case, younger versus older youths) even after controlling for levels of mania. Put another way, there would be differences in average scores on the item in question due to extraneous factors besides mania. Approximately 30% of mania items across four instruments showed evidence of uniform DIF associated with age. Interestingly, roughly half of the items had higher scores in the young group, and half in the older group, resulting in biases that tended to cancel out at the level of total scores. Items asking about distractibility, energy, motor activity tended to have higher scores in younger cases, independent of level of mania. Conversely, items assessing sleep disturbance, increased sociability, hypersexuality, mood swings, irritability, and suspiciousness tended to be higher in the adolescents even after controlling for level of mania. Non-uniform DIF refers to when the correlation between the item and the mania factor changes between groups. A similar number of items show evidence of non-uniform DIF related to age. Again, the tendency was for each instrument to include some items showing DIF in the opposite direction, with a net result being fairly consistent estimation of total scores within the same scale. On a global level, developmental changes in the rate of symptoms appear not to change the overall performance of rating scales appreciably, although there is evidence of more fine-grained developmental patterns that seem face valid and appear to replicate across instruments. ''Reliability and Credibility of Information Sources Across Age Cohorts'' As expected, caregiver report was the main source of information that could be used consistently across the ages from 5 to 18 years. Youth self-report on written questionnaires proved impractical before the age of 11 on most instruments. An innovation in this project was to keep track of the degree of assistance needed for the youth or caregiver to complete each instrument. Teacher report proved to be the least informative source of information about mood symptoms, despite our efforts to adapt instruments with good content coverage for use by teachers. Detailed evaluation of the psychometrics of four mania scales adapted for use by teachers have already been published (Youngstrom, Joseph, &  Greene, 2008). Interview-based information also could be used across the age-span, but the interviews were substantially different for young children versus adolescents. Often with young children the interview changed into a less structured interaction that provided an opportunity to conduct behavioral observations and probe key symptoms or events, whereas with adolescents it was usually possible to conduct an interview asking all the symptoms in a standard order. Based on this observation, we amended the protocol to start to systematically gather observational data using the Guide to the Assessment of Test Session Behavior (GATSB; Glutting & Oakland, 1993) for the last 100 cases, providing intriguing pilot data about the value of systematic observational ratings (consistent with the recent findings from other NIMH sponsored work, e.g., the DB-DOS)(Keenan & Wakschlag, 2002). We also had the interviewer rate the perceived credibility of the caregiver and the youth as a source of clinical information during the KSADS interview. At the end of the KSADS, interviewers rated 55% of caregivers “good” credibility, 37% “fair,” and 8% “poor;” versus 24% of youths “good,” 47% “fair,” and 30% “poor.” Credible youths tended to have credible caregivers, chi-squared (4 ''df'') = 48.86, ''p''<.00005; but there were still frequent mismatches, kappa=.16. Interviewers perceived caregivers as much more credible on average for the young children (ages 5 to 10 years): Cohen’s ''d''=1.15, ''p''<.00005; whereas caregivers were only slightly more credible for the older youths, ''d''=.27, ''p''=.001. Significant correlates of caregiver credibility included: younger age youth, better family functioning, better youth functioning, higher caregiver income or education, fewer children, and lower concerns about youth depression or manic symptoms. Regression analyses indicated that a combination of factors could explain 17% of the variance in caregiver credibility (''p''<.00005), with family functioning (''r<sub>part</sub>'' =.26), youth age (''r<sub>part</sub>''=-.21), credibility of the youth (''r<sub>part</sub>'' =.18), and caregiver education (''r<sub>part</sub>'' =.09) making significant unique contributions. Caregiver credibility was unrelated to caregiver mood symptoms, youth cognitive ability, or independent observations of youth behavior problems (cf. Youngstrom, Loeber, & Stouthamer-Loeber, 2000). Significant correlations of youth credibility were mostly different from the predictors of caregiver credibility, and included: older age youth, female youth, not having a diagnosis of ADHD or bipolar disorder, lower CBCL externalizing or attention problems, higher caregiver education, having a male primary caregiver, lower caregiver report of manic symptoms, and higher self-report of manic or depressive symptoms. A subset of cases also completed a brief intelligence test and had observational ratings of behavior available. Greater youth credibility was strongly associated with higher cognitive ability (''r''=.31) and less behavior problems during the KSADS interview (''r''=.43) or when watched by a different person while the caregiver was completing the KSADS (''r''=.31). Regression analyses indicated that factors could account for 22% of the credibility in youth report, with age being the strongest determinant. Controlling for youth age eliminated all other correlates except for caregiver credibility (''r<sub>part</sub>''=.18), with age remaining a powerful predictor (''r<sub>part</sub>''=.39). For the subset with cognitive ability and behavioral observations available, the regression explained a similar amount of variance, with age, cognitive ability, and observational ratings of behavior each making unique contributions, but caregiver credibility no longer significant. '''Associations Between Credibility and Validity:''' Ratings of caregiver credibility were strongly related to the validity of caregiver report on mood and behavior checklists. Validity coefficients for caregiver reported manic symptoms changed from .28 for poor credibility to .49 for good credibility when comparing GBI to YMRS ratings, and .51 to .63 for GBI to CDRS ratings. Areas Under the Curve in ROC analyses changes from .61 (ns) to .80 (''p''<.0005) for poor versus good credibility when comparing GBI scores to bipolar diagnoses. Caregiver-youth and caregiver teacher correlations all significantly increased when comparing good credibility to poor credibility caregivers, and this pattern was found across ratings of externalizing, internalizing, and attention problems as well as for manic and depressive symptoms (all ''p''<.05) (cf. Achenbach, McConaughy, & Howell, 1987). Similar patterns were observed with youth credibility. Interestingly, these patterns were not due to changes in the internal consistency of checklist scores: Cronbach’s alpha was often significant higher (''p''<.05 based on Feldt’s test) for the low credibility informants (Feldt, 1969). This suggests that many of the “low credibility” informants may have been sticking with a response set, such as minimizing or exaggerating problems, rather than providing nuanced information. Hypothesis 6: Bipolar spectrum disorders will be associated with progressively greater functional impairment, increased service utilization, increased burden, and decreased quality of life over time. The hypothesis that bipolar disorder is associated with greater burden and service utilization was partially supported. Bipolar disorder showed the greatest impact of any mental health condition on quality of life, matched only by unipolar depression, and exceeding almost all physical illnesses and disabilities for which benchmarking data are available (Freeman et al., 2009). Tables 19, 20, and 21 examine means by diagnostic subgroup. Table 22 presents impairment as a function of age cohort. Bipolar disorders were also associated with the highest levels of impairment on the Sheehan Disability Scales. However, there were no significant differences by age group on the level of impairment. Future analyses will investigate more fine-grained dissection of impact on specific domains by particular versions of bipolar disorder or distinct symptom clusters. ''Secondary aims:'' '''Base rate for juvenile BPSD in a community mental health setting''' A total of 620 families completed the KSADS evaluation at the community mental health center. The average youth met criteria for 3.7 Axis I diagnoses (median = 4, ''SD'' = 1.7). The most common category was externalizing disorders (67% of cases), with 65% meeting DSM-IV criteria for ADHD, 37% for ODD, and 13% for conduct disorder. Mood disorders were the second most common category, affecting 41% of youths, with anxiety disorders present in 26% of cases. Of the mood disorders, unipolar depression was the most common, affecting 11% of the sample, followed by minor depression (8%), bipolar NOS (5%), dysthymic disorder (4%), cyclothymic disorder (4%), bipolar I (3%), bipolar II (1%), and the remaining 5% consisting of a mixture of other mood issues not on the bipolar spectrum. Bipolar spectrum illnesses affected 13% of the sample (''n''=79). The bipolar NOS cases (''n''=29) were primarily considered NOS due to inadequate duration of hypomanic episodes (83%), versus having inadequate severity for mania (43%) or insufficient numbers of symptoms at threshold (30%). The majority of these NOS cases (''n''=18, 62%) would have met criteria for bipolar II disorder if the duration threshold for the hypomania were lowered to 2 days, as is currently being discussed in DSM-5 and was recommended in the ISBD Diagnostic Workgroup Papers (Ghaemi et al., 2008; Youngstrom, Birmaher, & Findling, 2008). The NOS label, as applied in this study, did not include chronically irritable youths without evidence of episodes or changes in mood or energy: 92% of NOS cases showed clear evidence of a cyclical mood course, with at least spontaneous shifts in mood and energy. Among the bipolar spectrum cases, 78% showed evidence of episodic elated mood, 69% of episodic irritable mood, and 44% showed grandiosity. This pattern was consistent across all four bipolar spectrum subgroups. There were no sex differences in rates of each type of bipolar, nor were their race/ethnicity differences in rates. There were trends for bipolar I and II to be more common in the older youths, and for cyclothymic disorder or bipolar NOS to be more common in the younger youths, but none of these trends achieved statistical significance. All of these patterns appear consistent with general trends emerging in the literature (Goodwin & Jamison, 2007; Kowatch, Youngstrom, Danielyan, & Findling, 2005). '''Diagnostic Agreement''' Goal: To examine the diagnostic agreement between diagnoses achieved via widely used methods: diagnosis as usual (DAU, reflecting the clinical standard of care), the KSADS-PL (the most widely used research instrument in projects evaluating mood disorder), and a Longitudinal Expert evaluation of All available Data (LEAD; reflecting the consensus diagnosis of clinical experts and raters after reviewing all available information). There were three different sets of diagnoses available for the cases interviewed at the CMHC: Intake diagnoses, KSADS diagnoses, and LEAD diagnoses. Intake diagnoses were “diagnosis as usual,” conducted following the normal procedures for the agency. More than 80% of the intakes were conducted by a masters level licensed clinical counselor or social worker with more than 10 years of experience, and almost all of the remainder were conducted by predoctoral psychology interns. The DAU intake interview consisted of an appointment of 90 minutes, of which roughly 30 minutes was spent completing consent forms and billing or insurance paperwork, and the remainder of which comprised an unstructured clinical interview assessing the presenting problem, prior developmental and treatment history, risk factors, strengths, and generating a five axis diagnostic formulation and initial treatment recommendations. The KSADS diagnoses were conducted by highly trained raters, either key personnel or predoctoral psychology interns electing to participate in the training as a formal year-long rotation offered during the internship year. Training focused heavily on the conceptualization of bipolar disorder (including 12 hours of didactic training based on the same content as the 7 hour continuing education offering presented by E. Youngstrom at the American Psychological Association, National Association of School Psychologists, Canadian Psychological Association, and Association for Behavioral and Cognitive Therapy conventions, but with expanded time for question and answer). The training emphasized use of DSM-IV diagnostic criteria, including the consideration of cyclothymic disorder and bipolar Not Otherwise Specified as well as bipolar II and bipolar I. Trainees learned about the “narrow phenotype” definition in 2003 with the publication of the Leibenluft et al. nosology (Leibenluft, et al., 2003), along with the varying definitions of the “broad phenotype” and “severe mood dysregulation.” However, the diagnostic definitions remained the same for the entire course of the grant, focusing on strict DSM criteria. Drift was avoided by using training videos from the early years of the grant as part of the training and certification process for subsequent years of the grant, as well as having the same two lead diagnosticians (EAY and JKY) leading the training for all years of the grant. Also important to note, the conceptualization of bipolar disorder always included the requirement that mood be episodic, involving a clear change from prior functioning. If the same symptom, such as poor concentration or motor agitation, followed a chronic course, then it was coded in a different section of the KSADS and not counted as well in the corresponding mood section. This is a neo-Kraepelinian formulation of bipolar disorder, emphasizing an episodic presentation. It is different from other formulations that allow a more insidious onset and chronic course. It also was expected that the emphasis on “finding each symptom the best home” in the KSADS would reduce the observed rates of comorbidity between bipolar and anxiety disorders or ADHD compared to rates found when using the KSADS without the same emphasis on episodicity. All raters completed the same training process, which required rating along with at least five interviews (watched live or from videorecording) conducted by a reliable rater, scoring along, and achieving an item-level kappa of .85 or greater. Once the trainee demonstrated the ability to match reliable ratings on five interviews, then the trainee led an interview with a reliable rater scoring along in real time. This next stage was crucial because of the semi-structured nature of the KSADS, which gives the interviewer flexibility to rephrase questions and involves a fair degree of clinical judgment in deciding when sufficient information has been elicited to score the symptom or module. Kappa evaluated agreement at the item level, and all scoring discrepancies were discussed. The reliable rater’s scores were the source document for the main dataset. Once the trainee led five interviews where their scores and the reliable rater’s scores converged kappa >= .85, then the trainee “graduated” to lead interviews independently. This training process was extremely time intensive, taking nine months to complete the training of the first cadre of raters, and never taking less than four months to complete the training. Once raters were reliable, they co-rated a live interview or re-rated from a videotape on a quarterly basis to avoid drift. More than thirty interns completed the training process, and only one withdrew from the rotation. Interns typically became reliable in 12 interviews (6+6). Feedback from the interns was consistently positive, with comments indicating that they found the training in diagnostic evaluation and conceptualization to be the most rigorous yet clinically useful that they had received in their training sequence. The CMHC also viewed the training as a valuable benefit of the collaboration between the agency and the university: The grant created a new training rotation for the internship which almost all subsequent interns selected, and it created new training materials and experiences that have continued to benefit the agency. KSADS scoring involved the same person interviewing both the caregiver and the youth. If there were significant discrepancies between the item scores based on the separate interviews, the rater used clinical judgment to resolve the discrepancy. They also were encouraged to re-interview either informant, or to discuss discrepancies with both simultaneously. After generating the summary scores for all symptoms and impairment criteria, DSM-IV algorithms were applied to arrive at the KSADS diagnoses. If the rater’s clinical impression was different than the diagnosis established by the algorithm, they wrote down their impression in addition to keeping the diagnosis from the KSADS, and both pieces of information were brought to the consensus conference.  The reliable rater recorded the KSADS diagnoses at the end of each interview, while still blind to other information such as the family mental health history, prior treatment history from the medical record, and all scores on the rating scales. The LEAD consensus meeting process used a team format. The reliable rater met with a licensed clinical psychologist (JKY, EAY, OIM, or NCF), along with a second person who had gathered the family history (either a research assistant or one of the predoctoral interns completing a fully-structured interview including the MINI and the Family History RDC), and photocopied the relevant prior diagnostic and treatment history from the medical record. The rating scales stayed recused from the diagnostic process, to ensure that the criterion diagnoses were “blind” to the instruments that would be evaluated as diagnostic predictors (Bossuyt et al., 2003). Final diagnoses were based on the KSADS, but could be modified on the basis of the interviewer’s clinical impressions, or additional information about family history or treatment history. The situations where a modification was most likely to occur involved diagnoses that are not formally assessed on the KSADS, such as pervasive developmental disorders (although most cases with clear pervasive developmental disorders were referred to other agencies prior to intake and so were unlikely to participate in the project). These three forms of diagnosis represent markedly different processes, ranging from a routine unstructured interview billable under CPT code 90801, to a semi-structured KSADS that required most of a day for the rater and family (and involving a minimum of 16-20 days of training and supervision spread over a period of months), to a consensus diagnosis that included all of the time, training and expense of the KSADs, along with an added person’s time gathering the family history and chart, and a licensed psychologist to spend an hour to review and synthesize the information. A recently published meta-analysis compared the agreement between unstructured clinical diagnoses and semi-structured or structured diagnostic interview results (Rettew, Lynch, Achenbach, Dumenci, & Ivanova, 2009). Typical agreement in the meta-analysis was kappa = .29 for externalizing disorders, .28 for internalizing disorders, but only .14 for affective disorders specifically (including bipolar disorder). Compared to these benchmarks, DAU fared slightly better than expected in terms of agreement with the KSADS or LEAD diagnoses for ADHD (kappa = .43 with LEAD, ''p'' < .00005) or disruptive behavior disorders (kappa = .35, ''p'' < .00005). However, DAU fared poorly with bipolar disorder: Kappa = .02, ''p'' < .01. Contrary to the popular concern about overdiagnosis of bipolar disorder, DAU was extremely conservative, only identifying bipolar in one case. This resulted in a diagnostic specificity of 100%, but a sensitivity of only 1%. Discussion with the clinicians clarified that they often had concerns about mood issues with a youth, but were highly reluctant to label a case as “bipolar” on the basis of a standard unstructured diagnostic interview. Instead, they were likely to diagnose “mood disorder Not Otherwise Specified,” and then often refer for psychiatric evaluation. When comparing this broader definition, combining bipolar disorder with mood NOS to form a “possible bipolar” group, then kappa with the LEAD bipolar spectrum diagnosis rose to .32, but with sensitivity only rising to 33% (indicating that the majority of bipolar cases remained undetected). Specificity appeared to stay high at 91%, but due to the low base rate of bipolar disorder at the CMHC, that still meant that the majority of cases (52%) identified as “possible bipolar” would actually be false positives. '''Secondary Aim: To promote the translation of assessment procedures from research tools to clinically useful instruments that are realistic to use in community mental health settings.''' Agreement between research diagnoses and clinical diagnosis was better than chance, but low, consistent with meta-analytic findings. DAU demonstrated extremely poor sensitivity to bipolar disorder, combined with a high false positive rate. On the basis of these findings, along with the promising results from the development of the screening instruments, the agency actually modified its intake procedure in several ways. The PGBI-10M became a standard part of the intake paperwork, and high scores on it, or else a clinical impression that suggests possible bipolar disorder, trigger a referral to a new diagnostic evaluation clinic where a specialist conducts a KSADS interview and gathers developmental and family history. Because the screening and clinical intake are sufficient to demonstrate medical necessity, the KSADS interview becomes a reimbursable service for Medicaid and other third party payors, billable under CPT Code 90801. This has navigated the transition from a grant sponsored activity to a self-sustaining clinical service that improves the diagnostic accuracy for the agency. '''Other Factors Potentially Changing Performance of Diagnostic Instruments''' As described above, there were cohort effects where depression severity tended to increase with age, versus mania severity tending to stay consistent or perhaps decrease slightly in adolescence. Investigation of differential item functioning in the manic symptoms indicated that some symptoms tend to increase in adolescence even after controlling for levels of underlying mania, and other symptoms decrease with age – with the net effect often cancelling out within the same scale. Similar analyses revealed no differences in total scores for mania comparing males versus females or White versus Black youths. DIF analyses at the item level revealed few examples of uniform or non-uniform bias in manic symptoms comparing across gender or ethnicity. Initial investigation of the role of parent mental health history suggests that the caregiver’s own history of mood disorder does not significantly change the validity of their report of the child’s functioning. The adult’s current mood status showed weak (''r''<.2) correlations with discrepancies between their perception and the youth’s own perception, consistent with prior investigations (Youngstrom, Ackerman, & Izard, 1999; Youngstrom, et al., 2000). Although more detailed analyses are needed to describe potential moderators of accuracy, the overarching pattern is that caregiver report is significantly more valid than youth or teacher report of manic symptoms, and this advantage persists even when the caregivers have a history of mood disorder themselves. '''Demographics and Participants''' The proposed research involves coordinated data collection at two sites: the research clinic at Case Western Reserve University/University Hospitals of Cleveland (CWRU/UHC), and the Cuyahoga County offices of Applewood Centers, Inc. (ACI). The integration of these two sites into one project creates a unique opportunity to translate clinical research into a more representative and applied setting. These two sites are complementary in crucial ways. CWRU/UHC has a referral system that is heavily enriched for BPSD (49% of 749 pilot cases meeting criteria for BPSD, and 18% for bipolar I), making it possible to   investigate a relatively infrequent disorder with smaller samples. Recruitment is enhanced by having a Stanley Foundation CCRC, having an adult Stanley-funded mood clinic (which refers children of identified bipolar parents for evaluation), having a variety of clinical trials available to provide free treatment to youths with bipolar disorder, having a national reputation for research in bipolar disorders, and having an extensive referral network throughout the region. The CWRU/UHC catchment area for mood disorders extends from Erie, PA to Toledo, OH, with many families driving three to four hours for treatment. However, ACI is a community mental health center (CMHC) that is both demographically more diverse and more representative of an urban community: 75% of the clients served by ACI are of diverse backgrounds, and 90% of families receive Medicaid. CWRU/UHC has the research infrastructure to complete detailed evaluations, and we propose adding a longitudinal component to this evaluation. ACI serves a dramatically larger volume of patients, with one county’s offices processing 10 to 20 times as many cases as CWRU/UHC per year. The research plan uses CWRU/UHC as a laboratory to develop and test measurement strategies, and ACI as the “field testing” to determine what is practical in real life community settings. The proposed design delivers on the promise of cross-validating measures in independent samples. This research will produce tools that will replicate better across research groups, as well as generalize to applied settings. = Inclusion Enrollment Report Table = {| class="wikitable" | colspan="7" |'''Study Title: ''' Improving the Assessment of Juvenile BPSD-Community Sample (ACI) |- | colspan="2" |'''Total Enrollment:''' 827 | colspan="5" | |- | colspan="2" |Grant Number: 5 R01 MH066647 | colspan="5" | |- | colspan="7" | '''PART A.

Alternatively, students may decide they are not good at math, or they dislike math, or they will never need to know math. This attitude of liking or disliking math can develop and solidify at any age and in a variety of contexts. The reasons for studying math presented here are similarly diverse. One reason may be convincing when presented to one student, and may be discouraging, annoying, or even offensive when presented to another student.

Examples include [[w:Euler's_identity|Euler's identity]] (e<sup>πi</sup> + 1 = 0), which combines five fundamental mathematical constants into a single equation, and the [[w:Pythagorean theorem|Pythagorean theorem]] (a<sup>2</sup> + b<sup>2</sup> = c<sup>2</sup>), which relates the sides of a right triangle in a beautifully straightforward manner. # '''Symmetry:''' Mathematics often involves the exploration of symmetry, both in geometric shapes and abstract concepts. Symmetrical patterns and equations are inherently pleasing to the eye, like the [[Math Adventures/Fibonacci and the Golden Ratio|Fibonacci sequence]] (0, 1, 1, 2, 3, 5, 8, 13, ...) found in many aspects of nature and art. # '''Unifying Principles:''' Math has a unique ability to unify seemingly unrelated ideas. For instance, calculus elegantly connects the concepts of differentiation and integration, showing how they are two sides of the same coin. This unification is profoundly beautiful. # '''Patterns and Fractals:''' Math helps us understand and appreciate the intricate patterns found in nature, from the branching of trees to the geometry of snowflakes. [[w:Fractal|Fractals]], such as the [[w:Mandelbrot_set|Mandelbrot set]], reveal stunning complexity emerging from simple equations. # '''Hidden Order:''' Math often uncovers hidden order within apparent chaos. [[w:Chaos_theory|Chaos theory]], for example, shows that seemingly random systems can have underlying patterns and predictability. This revelation of order is intellectually captivating. # '''Aesthetic Proofs:''' Mathematicians often seek not just to prove theorems but to find elegant and visually appealing proofs. These proofs are like works of art that convey complex ideas in a beautiful, understandable manner. # '''Puzzle Solving:''' [[Math Adventures|Mathematical puzzles]] and challenges can be like brain teasers, engaging our minds in playful and creative ways. The beauty lies in the satisfaction of solving these puzzles. # '''Universal Language:''' Math serves as a universal language that bridges cultures and languages. Its simplicity and universality are beautiful because they foster global communication and collaboration. # '''Historical Significance:''' The [[w:History_of_mathematics|history of mathematics]] is rich with stories of brilliant minds who made groundbreaking discoveries. Understanding the historical context and the struggle to uncover mathematical truths adds to the beauty of the subject. # '''Practicality and Utility:''' The beauty of math is not just abstract; it has practical applications in countless fields, from engineering and physics to computer science and economics. Seeing math in action, solving real-world problems, is inherently satisfying. In summary, the beauty of math lies in its ability to distill complex ideas into elegant simplicity, reveal hidden order, and provide a universal language for understanding and describing the world. It's a beauty that engages our minds, sparks creativity, and invites us to explore the awe-inspiring intricacies of the mathematical universe. == Further Reading == Students who are interested in cultivating interest in mathematics may wish to read these books: * {{cite book|title=Mathematics, Queen and Servant of Science|last=Bell|first=E.

The nature vs. nurture debate concerns the source or cause of criminality, especially as one ages into accountability for their behavior. The "nature" aspect puts fault on one's [[wikipedia:Genetic_predisposition|genetic predispositions]]<ref>{{Cite web|url=https://library.fiveable.me/key-terms/introduction-brain-behavior/genetic-predisposition|title=Genetic predisposition - (Intro to Brain and Behavior) - Vocab, Definition, Explanations {{!}} Fiveable|website=library.fiveable.me|access-date=2024-11-07}}</ref>. On the other hand, the "nurture" aspect is concerned with one's upbringing, living conditions, and environment. Throughout history, several theories have been posed whether nature or nurture cause crime. In this review, two theories will be analyzed and applied regarding pedophilia.[[File:Cesare Lombroso-scan by Alejandro Linconao-2012.jpg|thumb|270x270px|Cesare Lombroso's atavistic theory is not widely accepted today, but laid important foundations for the development of criminology as a whole.]] ==== Nature versus Nurture ==== The first theory is atavism, as applied to the field of criminology (circa 1870) by [[wikipedia:Cesare_Lombroso|Cesare Lombroso]]. He argued criminals possess [[wikipedia:Atavism|atavistic]] anomalies (physical features such as sloping forehead, ears of unusual size, asymmetry of the face, [[wikipedia:Prognathism|prognathism]], excessive length of arms, asymmetry of the cranium) that are passed genetically.<ref name=":0">{{Cite journal|last=Ellwood|first=Charles|date=1912-01-01|title=Lombroso's Theory of Crime|url=https://scholarlycommons.law.northwestern.edu/jclc/vol2/iss5/6/|journal=Journal of Criminal Law and Criminology|volume=2|issue=5|pages=716}}</ref><ref name=":1">{{Cite book|url=https://www.worldcat.org/title/on1285696621|title=Criminology|last=Siegel|first=Larry J.|date=2023|publisher=Cengage|isbn=978-0-357-62474-6|edition=Eighth edition|location=Boston, MA|oclc=on1285696621}}</ref><ref>{{Cite journal|last=Mazzarello|first=Paolo|date=2011|title=Cesare Lombroso: an anthropologist between evolution and degeneration|url=https://pubmed.ncbi.nlm.nih.gov/21729591/|journal=Functional Neurology|volume=26|issue=2|pages=97–101|issn=0393-5264|pmc=3814446|pmid=21729591}}</ref>. Lombroso's [[wikipedia:Eugenics|eugenic]] theories were disapproved throughout Europe (notably by [[wikipedia:Alexandre_Lacassagne|Alexandre Lacassagne]] and [[wikipedia:Charles_Buckman_Goring|Charles Goring]]) because they lacked rigorous statistical comparisons of criminals versus non-criminals. Nonetheless Lombroso laid an important road to studying criminals themselves rather than merely the crime<ref name=":0" />. On the other hand, the [[wikipedia:Social_learning_theory|social learning theory]] states that people are not inherently criminals but exhibit criminal-like behavior due to their upbringing or [[wikipedia:Social_environment|environment]]. For example, a son who watches his father abuse his mother might do the same later in life when dealing with his significant other.<ref name=":1" /> Notable psychologists, such as [[w:Albert_Bandura|Albert Bandura]], advocated for this theory, where people perceive the rewards for a crime higher than its consequences. The social learning theory expanded upon the "tremendous complexity of human responsiveness" by adding an additional element to the learning process: learning via rewards and consequences<ref>{{Cite book|title=Social learning theory|last=Bandura|first=Albert|date=1977|publisher=Prentice-Hall|isbn=978-0-13-816751-6|series=Prentice-Hall series in social learning theory|location=Englewood Cliffs, New Jersey}}</ref>. The nature vs. nurture debate in criminology has been a heated topic in the world of psychology and criminology for centuries. A common conclusion is that neither origin is solely responsible for criminal behavior. Criminal behavior is a combination of both nature and nurture done in a very "complex and not yet fully understood [way]"<ref name=":4" /> which leads to offensive or law-breaking behavior. Some scientists believe that the debate is unhelpful or outdated, while others hesitate that leaning to one-side over the other may fuel [[wikipedia:Bias|bias]]. For example, many people were forced sterile by [[wikipedia:Scientific_racism|scientific racism]]. Alternatively, too much emphasis on social conditions could cease progress for those riddled in poverty or other environmental disadvantages<ref name=":4">{{Cite journal|last=Levitt|first=Mairi|date=2013-12-12|title=Perceptions of nature, nurture and behaviour|url=https://lsspjournal.biomedcentral.com/articles/10.1186/2195-7819-9-13|journal=Life Sciences, Society and Policy|volume=9|issue=1|pages=13|doi=10.1186/2195-7819-9-13|issn=2195-7819|pmc=PMC4513026}}</ref>. [[File:Sexualisation model.pdf|left|thumb|300x300px|A model supposing pedophiles are a product of their upbringing. ]] ==== Studies ==== A 2009 study done on the etiology of pedophilia by researcher Juan Antonio Becerra García of the International University of La Rioja found several "structural deteriorations" within brain regions that were essential to sexual development, including a smaller right amygdala (less control over ability to inhibit certain behaviors), a significant decline of gray matter in the hypothalamus (which leads to a score of neurological issues, including memory loss and other cognitive impairments), and a decline in the activity of the dorsolateral prefrontal cortex (which leads to poor executive functioning)<ref name=":2">{{Cite journal|last=Becerra García|first=Juan Antonio|date=2009-01-01|title=Etiology of pedophilia from a neurodevelopmental perspective: markers and brain alterations|url=https://linkinghub.elsevier.com/retrieve/pii/S2173505009700512|journal=Revista de Psiquiatría y Salud Mental (English Edition)|volume=2|issue=4|pages=190–196|doi=10.1016/S2173-5050(09)70051-2|issn=2173-5050}}</ref>. Another review of the disorder published in 2015 affirmed that other studies conducted on pedophiles found similar findings, including a reduction of inhibition and executive functioning<ref>{{Cite journal|last=Tenbergen|first=Gilian|last2=Wittfoth|first2=Matthias|last3=Frieling|first3=Helge|last4=Ponseti|first4=Jorge|last5=Walter|first5=Martin|last6=Walter|first6=Henrik|last7=Beier|first7=Klaus M.|last8=Schiffer|first8=Boris|last9=Kruger|first9=Tillmann H.

However, García concluded that there really wasn't a "determinant explanation" for one to become a pedophile. García suggested that the brain abnormalities were brought about during neurodevelopment through "adverse events” but emphasizes that these cognitive shifts in the brain do not render an individual free from such horrific sexual crimes, if one were to act on such impulses<ref name=":2" />. Another study published in 2018, completed by Dr. Kelly M Babchishin and a team of researchers in Sweden, also mentioned that previous studies have found that pedophiles generally have a lower cognitive ability than non-pedophilic offenders and physical abnormalities that relate to neurological deficiencies<ref name=":3">{{Cite journal|last=Babchishin|first=Kelly M.|last2=Seto|first2=Michael C.|last3=Fazel|first3=Seena|last4=Långström|first4=Niklas|date=2019-02-12|title=Are There Early Risk Markers for Pedophilia?

However, Dr. Babchishin's study of 655 Swedish men convicted of child sex crimes yielded inconclusive and inconsistent results in pinpointing any "risk markers" for pedophilia, stating that there was no "clear evidence for the specificity of early risk markers for pedophilia"<ref name=":3" />. Although there are patterns of neurological deficiencies in pedophiles, no specific trait or gene propels an individual to sexual attraction of children. It is a myth that pedophiles arise from sexual abuse; this belief cannot be scientifically substantiated. Criminologist Richard Kelly affirms that a sizeable number of pedophiles "were abused themselves as children" but refuses to support the notion that pedophilia is brought on by past sexual abuses because it is "very difficult" to provide sufficient backing for such claims.<ref>{{Cite journal|last=Richards|first=Kelly|title=Misperceptions about child sex offenders|url=https://doi.org/10.52922/ti258908|journal=Trends & issues in crime and criminal justice|publisher=Australian Institute of Criminology|publication-date=30-09-2011|volume=429|issn=1836-2206}}</ref> ==== Conclusion ==== We do not have sufficient evidence to define the cause of pedophilia. Although poor executive functioning may be evident, this does not automatically cause a person to have sexual desires for children. In fact, arguing so would be a [[wikipedia:Questionable_cause|causal fallacy]]. There is also little evidence to support pedophilic attractions are solely brought on by one's environment. Pedophilia seems to be a mix between nature (one's body) and nurture (one's experiences). It is clear that more research should be done in this field. == See also == * [[w:Pedophilia|Pedophilia]] * [[w:Child_sexual_abuse|Child sexual abuse]] * [[w:Age_disparity_in_sexual_relationships|Age disparity in sexual relationships]] * [[wikipedia:Nature_versus_nurture|Nature versus Nurture]] * [[Criminology]] == References == {{Reflist}} [[Category:Atcovi's Work]] 539f5s9k8mvfa3uxp211gq3gm93tjmj 2809862 2809838 2026-05-17T04:30:33Z NguoiDungKhongDinhDanh 2922842 Reverted edit by [[Special:Contributions/HenriPittier|HenriPittier]] ([[User_talk:HenriPittier|talk]]) to last version by [[User:Atcovi|Atcovi]] using [[Wikiversity:Rollback|rollback]] 2715415 wikitext text/x-wiki {{Italic title}} {{Tertiary education}} {{psychology}} {{complete}}Pedophilia is the "persistent sexual interest in children (prepubescent)".<ref>{{Cite journal|last=Seto|first=Michael C.|date=2009-04-01|title=Pedophilia|url=https://www.annualreviews.org/doi/10.1146/annurev.clinpsy.032408.153618|journal=Annual Review of Clinical Psychology|language=en|volume=5|issue=1|pages=391–407|doi=10.1146/annurev.clinpsy.032408.153618|issn=1548-5943}}</ref> An official diagnosis of [[wikipedia:Pedophilia|pedophilia]], according to the [[wikipedia:ICD-11|International Classification of Diseases]], requires an individual has consistent sexual thoughts, urges, and illusions of children and to have either acted on these urges or be clearly distraught by these feelings.

The "nature" aspect puts fault on one's [[wikipedia:Genetic_predisposition|genetic predispositions]]<ref>{{Cite web|url=https://library.fiveable.me/key-terms/introduction-brain-behavior/genetic-predisposition|title=Genetic predisposition - (Intro to Brain and Behavior) - Vocab, Definition, Explanations {{!}} Fiveable|website=library.fiveable.me|access-date=2024-11-07}}</ref>. On the other hand, the "nurture" aspect is concerned with one's upbringing, living conditions, and environment. Throughout history, several theories have been posed whether nature or nurture cause crime. In this review, two theories will be analyzed and applied regarding pedophilia.[[File:Cesare Lombroso-scan by Alejandro Linconao-2012.jpg|thumb|270x270px|Cesare Lombroso's atavistic theory is not widely accepted today, but laid important foundations for the development of criminology as a whole.]] ==== Nature versus Nurture ==== The first theory is atavism, as applied to the field of criminology (circa 1870) by [[wikipedia:Cesare_Lombroso|Cesare Lombroso]]. He argued criminals possess [[wikipedia:Atavism|atavistic]] anomalies (physical features such as sloping forehead, ears of unusual size, asymmetry of the face, [[wikipedia:Prognathism|prognathism]], excessive length of arms, asymmetry of the cranium) that are passed genetically.<ref name=":0">{{Cite journal|last=Ellwood|first=Charles|date=1912-01-01|title=Lombroso's Theory of Crime|url=https://scholarlycommons.law.northwestern.edu/jclc/vol2/iss5/6/|journal=Journal of Criminal Law and Criminology|volume=2|issue=5|pages=716}}</ref><ref name=":1">{{Cite book|url=https://www.worldcat.org/title/on1285696621|title=Criminology|last=Siegel|first=Larry J.|date=2023|publisher=Cengage|isbn=978-0-357-62474-6|edition=Eighth edition|location=Boston, MA|oclc=on1285696621}}</ref><ref>{{Cite journal|last=Mazzarello|first=Paolo|date=2011|title=Cesare Lombroso: an anthropologist between evolution and degeneration|url=https://pubmed.ncbi.nlm.nih.gov/21729591/|journal=Functional Neurology|volume=26|issue=2|pages=97–101|issn=0393-5264|pmc=3814446|pmid=21729591}}</ref>. Lombroso's [[wikipedia:Eugenics|eugenic]] theories were disapproved throughout Europe (notably by [[wikipedia:Alexandre_Lacassagne|Alexandre Lacassagne]] and [[wikipedia:Charles_Buckman_Goring|Charles Goring]]) because they lacked rigorous statistical comparisons of criminals versus non-criminals. Nonetheless Lombroso laid an important road to studying criminals themselves rather than merely the crime<ref name=":0" />. On the other hand, the [[wikipedia:Social_learning_theory|social learning theory]] states that people are not inherently criminals but exhibit criminal-like behavior due to their upbringing or [[wikipedia:Social_environment|environment]]. For example, a son who watches his father abuse his mother might do the same later in life when dealing with his significant other.<ref name=":1" /> Notable psychologists, such as [[w:Albert_Bandura|Albert Bandura]], advocated for this theory, where people perceive the rewards for a crime higher than its consequences. The social learning theory expanded upon the "tremendous complexity of human responsiveness" by adding an additional element to the learning process: learning via rewards and consequences<ref>{{Cite book|title=Social learning theory|last=Bandura|first=Albert|date=1977|publisher=Prentice-Hall|isbn=978-0-13-816751-6|series=Prentice-Hall series in social learning theory|location=Englewood Cliffs, New Jersey}}</ref>. The nature vs. nurture debate in criminology has been a heated topic in the world of psychology and criminology for centuries. A common conclusion is that neither origin is solely responsible for criminal behavior. Criminal behavior is a combination of both nature and nurture done in a very "complex and not yet fully understood [way]"<ref name=":4" /> which leads to offensive or law-breaking behavior. Some scientists believe that the debate is unhelpful or outdated, while others hesitate that leaning to one-side over the other may fuel [[wikipedia:Bias|bias]]. For example, many people were forced sterile by [[wikipedia:Scientific_racism|scientific racism]]. Alternatively, too much emphasis on social conditions could cease progress for those riddled in poverty or other environmental disadvantages<ref name=":4">{{Cite journal|last=Levitt|first=Mairi|date=2013-12-12|title=Perceptions of nature, nurture and behaviour|url=https://lsspjournal.biomedcentral.com/articles/10.1186/2195-7819-9-13|journal=Life Sciences, Society and Policy|volume=9|issue=1|pages=13|doi=10.1186/2195-7819-9-13|issn=2195-7819|pmc=PMC4513026}}</ref>. [[File:Sexualisation model.pdf|left|thumb|300x300px|A model supposing pedophiles are a product of their upbringing. ]] ==== Studies ==== A 2009 study done on the etiology of pedophilia by researcher Juan Antonio Becerra García of the International University of La Rioja found several "structural deteriorations" within brain regions that were essential to sexual development, including a smaller right amygdala (less control over ability to inhibit certain behaviors), a significant decline of gray matter in the hypothalamus (which leads to a score of neurological issues, including memory loss and other cognitive impairments), and a decline in the activity of the dorsolateral prefrontal cortex (which leads to poor executive functioning)<ref name=":2">{{Cite journal|last=Becerra García|first=Juan Antonio|date=2009-01-01|title=Etiology of pedophilia from a neurodevelopmental perspective: markers and brain alterations|url=https://linkinghub.elsevier.com/retrieve/pii/S2173505009700512|journal=Revista de Psiquiatría y Salud Mental (English Edition)|volume=2|issue=4|pages=190–196|doi=10.1016/S2173-5050(09)70051-2|issn=2173-5050}}</ref>.

However, García concluded that there really wasn't a "determinant explanation" for one to become a pedophile. García suggested that the brain abnormalities were brought about during neurodevelopment through "adverse events” but emphasizes that these cognitive shifts in the brain do not render an individual free from such horrific sexual crimes, if one were to act on such impulses<ref name=":2" />. Another study published in 2018, completed by Dr. Kelly M Babchishin and a team of researchers in Sweden, also mentioned that previous studies have found that pedophiles generally have a lower cognitive ability than non-pedophilic offenders and physical abnormalities that relate to neurological deficiencies<ref name=":3">{{Cite journal|last=Babchishin|first=Kelly M.|last2=Seto|first2=Michael C.|last3=Fazel|first3=Seena|last4=Långström|first4=Niklas|date=2019-02-12|title=Are There Early Risk Markers for Pedophilia?

However, Dr. Babchishin's study of 655 Swedish men convicted of child sex crimes yielded inconclusive and inconsistent results in pinpointing any "risk markers" for pedophilia, stating that there was no "clear evidence for the specificity of early risk markers for pedophilia"<ref name=":3" />. Although there are patterns of neurological deficiencies in pedophiles, no specific trait or gene propels an individual to sexual attraction of children. It is a myth that pedophiles arise from sexual abuse; this belief cannot be scientifically substantiated. Criminologist Richard Kelly affirms that a sizeable number of pedophiles "were abused themselves as children" but refuses to support the notion that pedophilia is brought on by past sexual abuses because it is "very difficult" to provide sufficient backing for such claims.<ref>{{Cite journal|last=Richards|first=Kelly|title=Misperceptions about child sex offenders|url=https://doi.org/10.52922/ti258908|journal=Trends & issues in crime and criminal justice|publisher=Australian Institute of Criminology|publication-date=30-09-2011|volume=429|issn=1836-2206}}</ref> ==== Conclusion ==== We do not have sufficient evidence to define the cause of pedophilia. Although poor executive functioning may be evident, this does not automatically cause a person to have sexual desires for children. In fact, arguing so would be a [[wikipedia:Questionable_cause|causal fallacy]]. There is also little evidence to support pedophilic attractions are solely brought on by one's environment. Pedophilia seems to be a mix between nature (one's body) and nurture (one's experiences). It is clear that more research should be done in this field. == See also == * [[w:Pedophilia|Pedophilia]] * [[w:Child_sexual_abuse|Child sexual abuse]] * [[w:Age_disparity_in_sexual_relationships|Age disparity in sexual relationships]] * [[wikipedia:Nature_versus_nurture|Nature versus Nurture]] * [[Criminology]] == References == {{Reflist}} [[Category:Atcovi's Work]] 0qjeyfqxdlowxo92qctb8j06126816k International Communication Law 0 317777 2809752 2809634 2026-05-16T21:02:10Z Mendezre 3076329 2809752 wikitext text/x-wiki {{law}} {| style="width:100%; margin-bottom: .6em; -moz-border-radius: 4px; text-align:center; border: 1px solid #50A6C2; background-color:#F0F8FF; padding: .6em .6em .6em .6em;" |<div style="font-size:200%;border:none;margin: 0;padding:.1em;color:#000">'''International Communication Law Learning Project'''</div><div style="top:+0.2em;font-size:150%">part of the [[School:Law|'''School of Law''']]</div> |} {{SearchWithPrefix}}'''[[Help:Resources by subject|Subject classification]]''': this is a [[Portal:Law|law learning projects]] resource.

Beyond the macroscopic scale, CIT proposes that mass-energy influx also influences '''microscopic phenomena''' such as Van der Waals forces, the Casimir effect... [[User:Ruud_Loeffen/Cosmic_Influx_Theory(3)/Chapter_8#8.2.10|[8.2.10]]], and even the trajectory of falling raindrops. These phenomena may provide subtle but crucial evidence of a pervasive cosmic influx shaping both the vast and the minuscule aspects of the universe. By delving into the '''Gravitational Constant''', we unveil compelling evidence for an '''increase in mass and heat''' for all celestial objects within an isotropic and homogenous universe as a result of the '''Lorentz Transformation of Mass- Energy''' (LTME) [[User:Ruud_Loeffen/Cosmic_Influx_Theory(3)/Chapter_8#8.1.1|[8.1.1]]]. [[File:Influx formula with midocean ridge ml resize x4.png|thumb|Illustration of Cosmic Influx Theory (CIT), showing energy influx, planetary surface area, and geophysical processes such as mid-ocean ridge formation.]] Traditionally, LTME has been considered relevant primarily for '''subatomic particles''' at '''high''' velocities. However, this study posits that LTME is equally applicable to '''big celestial bodies''', even at relatively '''low velocities'''. CIT introduces the concept of a '''universal energy influx''', hypothesized as a stream of "whirlings" or "excitations" interacting with the kinetic energy of atoms, driving incremental mass increases in alignment with the Lorentz Transformation of Mass-Energy (LTME) [[User:Ruud_Loeffen/Cosmic_Influx_Theory(3)/Chapter_8#8.7.2|[8.7.2]]] This mechanism offers a unified explanation for geological phenomena such as '''volcanic activity, seafloor spreading, and planetary expansion''' [[User:Ruud_Loeffen/Cosmic_Influx_Theory(3)/Chapter_8#8.4.15|[8.4.15]]] [[User:Ruud_Loeffen/Cosmic_Influx_Theory(3)/Chapter_8#8.4.20|[8.4.20]]], while also addressing cosmological questions such as galactic rotation curves and cosmic acceleration. Key results include calculated mass-energy growth rates consistent with geological observations as described by many researchers on '''Earth Expansion''' and '''Expansion Tectonics''' [[User:Ruud_Loeffen/Cosmic_Influx_Theory(3)/Chapter_8#8.4.20|[8.4.20]]] [[User:Ruud_Loeffen/Cosmic_Influx_Theory(3)/Chapter_8#8.4.21|[8.4.21]]], a redefinition of gravitational acceleration through the volumetric universal influx. By integrating CIT with established physics principles and observational data, this paper highlights its potential to bridge gaps in mainstream models of dark matter and dark energy [[User:Ruud_Loeffen/Cosmic_Influx_Theory(3)/Chapter_8#8.1.2|[8.1.2]]]. Importantly, '''CIT does not reject the occurrence of subduction zones'''. Rather, it integrates subduction as a natural consequence of localized surface adjustments during global expansion. While oceanic crust is created at mid-ocean ridges, older, '''denser crust may subduct along continental margins, often accompanied by mountain building'''. However, the net balance, according to CIT, is a continuous increase in the total mass and volume of celestial bodies. A more detailed discussion on how subduction and expansion coexist within CIT is presented in '''[[User:Ruud_Loeffen/Cosmic_Influx_Theory(3)/Chapter_5#5.3_Geophysical_Evidence:_Plate_Tectonics_and_Planetary_Evolution|Chapter 5.3]]'''. This pursuit contemplates the possibility of an infinitely energetic universe, where energy metamorphoses into mass through <math>M = \frac{E}{c^2}</math> This interpretation proposes the existence of a '''Process of Continuously Created Matter''', manifesting as an ongoing accretion, augmentation, and expansion, harmonizing with the universe's ever-expansive nature [[User:Ruud_Loeffen/Cosmic_Influx_Theory(3)/Chapter_8#8.4.7|[8.4.7]]]. CIT introduces the '''Preferred Distance (D<sub>pref</sub>)''', derived from the '''Root Mean Square Velocity (VRMS)''' of planetary systems (see Chapter 2 for explanation)[[User:Ruud_Loeffen/Cosmic_Influx_Theory(3)/Chapter_8#8.7.3|[8.7.3]]], as a key factor in structuring planetary orbits. This theory challenges conventional gravitational models by linking the '''gravitational constant (G)''' to the Lorentz transformation and vacuum energy properties [[User:Ruud_Loeffen/Cosmic_Influx_Theory(3)/Chapter_8#8.7.8|[8.7.8]]]. [[File:Iiif-service gmd gmd9 g9096 g9096c ct003148-full-pct 12.5-0-default.jpg|thumb|World Ocean Floor (1977). Originally used to support the theory of Plate Tectonics, this image also offers a compelling perspective on the potential increase of mass-energy over time, aligning with Cosmic Influx Theory (CIT).]] The purpose of this Wikiversity page is to present CIT in a structured and accessible format, supported by mathematical derivations, observational data, and theoretical discussions. == Introduction to the Cosmic Influx Theory (CIT) using NotebookLM and YouTube == We used NotebookLM to generate an interactive Q&A format with two AI interviewers. These interviewers read the Cosmic Influx Theory (CIT) and provide analysis through questions and answers. From this audio material, we created the video: [https://youtube.com/watch?v=cy9zhC3kcYU&si=2NGLwz3aIE_6Gbba ''Two AI interviewers discuss Gravity and Influx'']. In this video, two AIs (Q and A) explore the Cosmic Influx Theory (CIT) — a bold idea that challenges Newton’s apple and Einstein’s spacetime. Instead of attraction, gravity may be the result of a continuous influx of cosmic energy, pressing down from all sides and driving the growth of matter, planets, and even the universe itself.

It was created by David Baszucki and Erik Cassel in 2004 and was made available in 2006. <ref>{{Cite web|url=https://en.wikipedia.org/wiki/Roblox|title=Roblox|date=2019-02-15|website=Wikipedia|language=en}}</ref> As of 2024, there are about 80 million daily active users on Roblox, mainly children and teenagers under 18. <ref>{{Cite web|url=https://backlinko.com/roblox-users|title=Roblox Usage and Growth Statistics You Need to Know|date=2024-01-17|website=Backlinko|language=en}}</ref> == Tower Defense Game History == In Roblox, there are many genres of games, including tower defense. Tower Defense is a strategy game genre where players defend their territory or base by placing defensive structures, such as people or buildings, in strategic locations to prevent waves of enemies from reaching the end. The tower defense era on Roblox started a year after the platform was made public. It was made known in 2007, and these games are somewhat popular today. There are numerous tower defense games on Roblox. ===Roblox Tower Defense Beta v1.0=== This game was the first-ever tower defense game on Roblox. It was created in 2007 by Naxic and had pretty awesome mechanics for an old game. There are a decent number of towers, and the game was straightforward and enjoyable. Not much information is known about this game, but it was the starting point of something bigger. <ref>{{Cite web|url=https://www.youtube.com/watch?v=fFSApG6rDvw|title=The ENTIRE History of Roblox Tower Defense|date=2024-12-14|website=YouTube|language=en}}</ref> === Tower Battles === Tower Battles was the first huge tower defense game on Roblox to be released. It was created by Planet3arth in 2011 but was officially released in 2017. The creator expanded upon the tower defense genre by adding a competitive multiplayer game mode where players can send offensive enemies on the opponents' side to try and make them lose. Not only do you need to defend the normal wave of enemies, but you also need to hold off the enemies your opponents send you. This changes your strategy up as different players would defend differently, get further into the match, and send different, strong enemies in your way. There are a huge number of towers to choose to defend the enemies with. Since there are only 5 towers to take with you in a match and each tower has its own mechanic, players have to strategize what to bring. Some towers can freeze enemies, deal splash damage, and more! To get these towers, you have to unlock them using coins you get from losing or winning a round. This gets players consistently playing the game to get coins to unlock more towers. Even though it's a long journey to get coins, it has replay value. Even after 10 years and minimal updates, the game is still pretty popular and well-known. A lot of Roblox users would remember this game in the future (Tower Battles Wiki). ===MechaCubes=== MechaCubes was another notable tower defense game released in 2015 by a group named Tuning Studios. It's run by the Roblox users named toonicooooooos, the amazingkang, and Lenny. The game is inspired by Bloons Tower Defense, a well-known tower defense game on the internet. It was very popular back then since it had a lobby with leaderboards that showed the players' rank, total cash, and wins. You can search for certain players to see their game stats. A new and cool feature in this game is the perks that players can buy using the game currency. These perks work on specific towers and can boost their stats, and usually have a downside as well. For example, a perk can boost their damage but lower their fire rate. These perks can change players' strategies and give them a massive combination of towers and perks to choose from to defend the enemies. Players can also trade these perks with other players! Just like Tower Battles, the gameplay is straightforward. The main difference is that you unlock towers by leveling up and getting experience from losing or winning rounds. There are many towers to use and defend with though. Another cool thing is that players can rejoin the same match if they disconnect or leave the round. Many tower defense games don't have this feature. In the modern day, MechaCubes isn't receiving any updates anymore and isn't popular, but it's still a nostalgic tower defense game to come back to (MechaCubes Wiki). === Tower Defense Simulator === Tower Defense Simulator, also commonly known as TDS, was the most popular tower defense game on Roblox until the modern day. It was created in 2018 by the group Paradoxum Games, with the lead developer being BelowNatural. It was inspired by Tower Battles and marked a milestone for modern-day tower defense games. It redefined what tower defense games are on Roblox. The popularity of the game was influenced by its astonishing game mechanics and design. It has a clean UI, numerous amount of towers, many abilities, game dialogue, unique enemies, four different game modes, original music, and a nice community. The game also receives consistent updates even in the modern day, giving players more of a reason to play the game. In 2020, the game reached its milestone of one billion visits, which is a huge achievement and goes down in Roblox history. A huge aspect that brings a mass amount of players into the game is its seasonal events. Their first ever event was Sword Fight on The Heights (SFOTH), featuring a new map, totally different enemies, and a unique boss. It gave the players something new and exciting to experience other than the four main modes. These events usually reward a limited-time tower that is strong in certain scenarios. There are over 15 unique events, and continues to rise as the game continues to be popular. Tower Defense Simulator has changed a lot since its first release. It has gotten numerous updates, gameplay, and design changes to make it appealing in the modern day. The game has won many Roblox awards and will continue to be well-known in the future (Tower Defense Simulator Wiki). === All Star Tower Defense === All Star Tower Defense, or ASTD, immediately grew popular when it was released. It was created by the group Top Down Games and was released to the public in 2020. This game has basic tower defense game mechanics, but what made it popular was the addition of anime. As many people watched anime, the creators threw the idea of adding famous anime characters into a Roblox game. Characters such as Naruto and Goku were included to attract people. This game is unique from the recent tower defense games because it includes a gacha system. Gacha is derived from a Japanese word meaning a vending machine, meaning players spend their in-game currency for a chance to get a random tower. It's up to luck to decide whether players get a strong or weak tower, depending on the probability listed. This mechanic fueled people's drive to keep playing the game to get more currency and try their luck for a rare and strong tower. Even though it'll get some hate from some players, this mechanic is what allows replayability and the consistent visits. The gacha system and anime theme work together to form the growing popularity of this game. This game inspired many future tower defense games to add a gacha system for getting towers as well (All Star Tower Defense Wiki). === World Tower Defense === World Tower Defense is a unique tower defense that slowly gained its popularity with its unique gameplay. The game was created in 2021 by the group named Select an Image from Your Computer Studios, with its main developer being Babygoo25. This game was inspired by The Battle Cats and expanded upon it. This game is notable since it features maps with no designated paths for the enemies to follow. It also brings the mechanic that all towers can die from the enemies. This is the first tower defense game on Roblox to implement the idea that towers that are placed are directly targeted by enemies and can get killed by them. This mechanic is what makes the game extremely difficult and encourages trial and error to beat all the modes. Due to its difficulty, many players quit, but many are motivated to take on this arduous challenge. The game started weak and unbalanced, but as time went on, it received consistent and frequent updates that added new towers, modes, enemies, and even some lore! The game is somewhat popular today, and the main developer is actively working on new content for players to enjoy. Overall, its uniqueness and high stakes are what make this game enjoyable. <ref>{{Cite web|url=https://www.roblox.com/games/5656754541/World-Tower-Defense|title=World Tower Defense|date=2025|website=Roblox|language=en}}</ref> === Tower Galactica === Tower Galactica is another unique and once-popular tower defense game on Roblox. It was created by Eraptyy and was released in early 2022. The theme of this game is space, and it features an engaging storyline that captures players' attention. There are different planets to visit, and you have to defend against waves of enemies on each one to progress. This pushes users to keep playing to discover new enemies and what happens next in the story. What makes this game so unique is that it gives the enemies the ability to attack players instead of only the towers. The player will have a certain number of lives, and the game will end if all players lose all their lives to the enemies or their surroundings. As a result, all players will have to be careful of getting too close to the enemies and avoid getting damaged from anything that can hurt them. This turns this game intense, which draws the attention of many players to attempt to get to the end and conquer the enemies. This mechanic is rarely used since it doesn't fit the traditional tower defense ways, though. This game gained popularity due to its amazing storyline and lives mechanic, but it soon died out when the developers lost the motivation to continue updating the game with more planets and lore. However, this game will be remembered as the most interactive and movement-intense tower defense game on Roblox (Tower Galactica Wiki). == Impact on Roblox == Tower defense wasn't the most popular genre on Roblox in the past. However, as these breathtaking games started popping up, it became well-known, and the genre is now one of the biggest on Roblox. In the modern day, there are over 100 great tower defense games to choose and play from. As new ideas and mechanics are implemented into future games, this genre isn't losing its popularity soon. <ref>{{Cite web|url=https://www.youtube.com/watch?v=fFSApG6rDvw|title=The ENTIRE History of Roblox Tower Defense|date=2024-12-14|website=YouTube|language=en}}</ref> == List of Popular Tower Defense Games == As of March 2025, here are 10 popular tower defense games on Roblox. 1.

It was created by David Baszucki and Erik Cassel in 2004 and was made available in 2006. <ref>{{Cite web|url=https://en.wikipedia.org/wiki/Roblox|title=Roblox|date=2019-02-15|website=Wikipedia|language=en}}</ref> As of 2024, there are about 80 million daily active users on Roblox, mainly children and teenagers under 18. <ref>{{Cite web|url=https://backlinko.com/roblox-users|title=Roblox Usage and Growth Statistics You Need to Know|date=2024-01-17|website=Backlinko|language=en}}</ref> == Tower Defense Game History == In Roblox, there are many genres of games, including tower defense. Tower Defense is a strategy game genre where players defend their territory or base by placing defensive structures, such as people or buildings, in strategic locations to prevent waves of enemies from reaching the end. The tower defense era on Roblox started a year after the platform was made public. It was made known in 2007, and these games are somewhat popular today. There are numerous tower defense games on Roblox. ===Roblox Tower Defense Beta v1.0=== This game was the first-ever tower defense game on Roblox. It was created in 2007 by Naxic and had pretty awesome mechanics for an old game. There are a decent number of towers, and the game was straightforward and enjoyable. Not much information is known about this game, but it was the starting point of something bigger. <ref>{{Cite web|url=https://www.youtube.com/watch?v=fFSApG6rDvw|title=The ENTIRE History of Roblox Tower Defense|date=2024-12-14|website=YouTube|language=en}}</ref> === Tower Battles === Tower Battles was the first huge tower defense game on Roblox to be released. It was created by Planet3arth in 2011 but was officially released in 2017. The creator expanded upon the tower defense genre by adding a competitive multiplayer game mode where players can send offensive enemies on the opponents' side to try and make them lose. Not only do you need to defend the normal wave of enemies, but you also need to hold off the enemies your opponents send you. This changes your strategy up as different players would defend differently, get further into the match, and send different, strong enemies in your way. There are a huge number of towers to choose to defend the enemies with. Since there are only 5 towers to take with you in a match and each tower has its own mechanic, players have to strategize what to bring. Some towers can freeze enemies, deal splash damage, and more! To get these towers, you have to unlock them using coins you get from losing or winning a round. This gets players consistently playing the game to get coins to unlock more towers. Even though it's a long journey to get coins, it has replay value. Even after 10 years and minimal updates, the game is still pretty popular and well-known. A lot of Roblox users would remember this game in the future (Tower Battles Wiki). ===MechaCubes=== MechaCubes was another notable tower defense game released in 2015 by a group named Tuning Studios. It's run by the Roblox users named toonicooooooos, the amazingkang, and Lenny. The game is inspired by Bloons Tower Defense, a well-known tower defense game on the internet. It was very popular back then since it had a lobby with leaderboards that showed the players' rank, total cash, and wins. You can search for certain players to see their game stats. A new and cool feature in this game is the perks that players can buy using the game currency. These perks work on specific towers and can boost their stats, and usually have a downside as well. For example, a perk can boost their damage but lower their fire rate. These perks can change players' strategies and give them a massive combination of towers and perks to choose from to defend the enemies. Players can also trade these perks with other players! Just like Tower Battles, the gameplay is straightforward. The main difference is that you unlock towers by leveling up and getting experience from losing or winning rounds. There are many towers to use and defend with though. Another cool thing is that players can rejoin the same match if they disconnect or leave the round. Many tower defense games don't have this feature. In the modern day, MechaCubes isn't receiving any updates anymore and isn't popular, but it's still a nostalgic tower defense game to come back to (MechaCubes Wiki). === Tower Defense Simulator === Tower Defense Simulator, also commonly known as TDS, was the most popular tower defense game on Roblox until the modern day. It was created in 2018 by the group Paradoxum Games, with the lead developer being BelowNatural. It was inspired by Tower Battles and marked a milestone for modern-day tower defense games. It redefined what tower defense games are on Roblox. The popularity of the game was influenced by its astonishing game mechanics and design. It has a clean UI, numerous amount of towers, many abilities, game dialogue, unique enemies, four different game modes, original music, and a nice community. The game also receives consistent updates even in the modern day, giving players more of a reason to play the game. In 2020, the game reached its milestone of one billion visits, which is a huge achievement and goes down in Roblox history. A huge aspect that brings a mass amount of players into the game is its seasonal events. Their first ever event was Sword Fight on The Heights (SFOTH), featuring a new map, totally different enemies, and a unique boss. It gave the players something new and exciting to experience other than the four main modes. These events usually reward a limited-time tower that is strong in certain scenarios. There are over 15 unique events, and continues to rise as the game continues to be popular. Tower Defense Simulator has changed a lot since its first release.

But the core samples of the oceanic crust show that the Earth has expanded. ====What about the uniqueness of the animals in Australia?==== It's just like Galapagos island. Adaptation and environmental favorability for particular species would produce vast differences at least in some places of the Earth over 4,388 years after the flood. ===theory under review=== ====Deluge Geology, Radio Dating Inaccuracy, and Creative Days==== Facts; (1) the radioactive decay rate is NOT a constant; neutrino intensity definitely effects the radioactive decay rate; https://web.archive.org/web/20150528020329/http://news.stanford.edu/news/2010/august/sun-082310.html The higher the neutrino intensity the lower the radioactive decay rate. (2) atmospheric electrons backscatter neutrinos increasing the intensity of neutrino radiation towards the earth (the atmosphere is a converging lens to neutrinos) An Earth with a larger atmosphere (such as one that had all the oceanic water as a gas or plasma in a gigantic ionosphere) would increase the intensity of neutrino radiation towards the earth and given fact 1, lower the radioactive decay rate of radioisotopes. (3) the continental plates fit together completely on a smaller Earth; https://www.youtube.com/watch?v=cnEkFofRFx0 (4) land fossils prove most of the Earth continental plates have been dry land (5) on a smaller Earth (with all the continental plates put back together) the oceanic water would cover the entire Earth (6) given fact 4, and 5, it follows that the oceanic water in the past was not on land (rather it must have been in the atmosphere so that it could fall to Earth). (7) given fact 3, and 6, it follows that the Earth was smaller with a gigantic gaseous or plasma water canopy (8) given fact 5, and 7, it follows that there was a global flood!!! (9) but given 2, and 7, it follows that the radioactive decay rate was significantly lower before the flood (10) given 9, the radio dating methods that assume constants in the radioactive decay rates are absolutely inaccurate (though still having good precision) (11) the flood must be the last mass extinction event (12) the K-T iridium aerosols [presumably from meteoroids] and any possible volcanic ash would have acted like cloud condensation nuclei, cloud seeding the deluge (13) if God saved all the original animals in the Ark then the genera after the flood (notice blue line) matches the genera at Adam's creation (notice yellow line) proving God saved all the original animals; https://commons.wikimedia.org/wiki/File:Phanerozoic_Biodiversity-2.png (14) If we assume that Adam was 44a when Eve was born and that the creative days are 221Ma (according to the dating inaccuracy) then a creative day is 9,500 years Eve became the Mother of Seth at 86a. Genesis 5:3 Seth became the father of Enosh at 105. Genesis 5:6 Enosh became the father of Kenan at 90. Genesis 5:9 Cainan became the father of Mahalalel at 70. Genesis 5:12 Mahalalel became the father of Jared at 65. Genesis 5:15 Jared became the father of Enoch at 162. Genesis 5:18 Enoch became the father of Methuselah at 65. Genesis 5:21 Methuselah became the father of Lamech at 187. Genesis 5:25 Lamech became the father of Noah at 182. Genesis 5:28 The Flood started when Noah was 600. Genesis 7:6 (86+105+90+70+65+162+65+187+182+600)=1612a of creative day seven [Eve's creation to the flood] 1612a*221/37.5=9500 [this is a creative day] Fifth day 510 Ma the first fish, the jawless ostracoderms. 410 Ma the first fish with jaws, the acanthodians. 365 Ma the tetrapods. 350 Ma the dragonfly (the first flying creatures were insects). 340 Ma the amniotes. And God went on to say: Let the waters swarm forth a swarm of living souls and let flying creatures fly over the earth upon the face of the expanse of the heavens. And God proceeded to create the great monsters and every living soul that moves about, which the waters swarmed forth according to their kinds, and every winged flying creature according to its kind. And God got to see that [it was] good. ... And there came to be evening and there came to be morning, a fifth day. (Genesis 1:20-23) Surprisingly enough, the flying creatures in this verse is not birds (as many may have thought), rather, '''it is insects'''! Sixth day 285 Ma the therapsids. 230 Ma the dinosaurs. 225 Ma the first true mammals, Gondwanadon tapani or Morganucodon watsoni. 150 Ma the first bird, Archaeopteryx. And God went on to say: Let the earth put forth living souls according to their kinds, domestic animal and moving animal and wild beast of the earth according to its kind. And it came to be so. And God proceeded to make the wild beast of the earth according to its kind and the domestic animal according to its kind and every moving animal of the ground according to its kind. And God got to see that [it was] good. (Genesis 1:24, 25) As you can see this work clarified our understanding of the bible (first flying creatures are insects) and the creation of the other animals matches the day of their biblical creation (15) since the creation of Eve to the present it's been about 6000a (16) Tyranusourus Rex fossils are dated between the creation of Eve and the date of the Flood; somewhere around 800a of creative day seven or ~5,200 years ago (inaccurately dated to 80Ma) https://s.hdnux.com/photos/10/17/62/2161798/6/1200x0.jpg https://www.science.org/cms/10.1126/science.1108397/asset/f350e639-3ffd-48d9-a488-2dfa943596dd/assets/graphic/307_1952_f2.jpeg How old is this T. Rex blood and soft tissue? 5,200 years old or 80 MILLION years old? I predict that the soft tissue found in T. Rex bone will Carbon 14 date to around 5,200 years old! This will verify my theory about the Deluge Geology, Radio Dating Inaccuracy, and Creative Days. That said, how could man, birds, and land animals have survived the deluge? According to the bible (and over a hundred of other ancient sources), there was a great flood that destroyed the ancient world, for which, the gods spared some men and animals. Jehovah claimed to cause the flood. In any cause we must grant at least the existence of advanced extraterrestrials (or gods exist or even that God exists) such that they could have spared some men, otherwise, mankind and all the animals on land could not have possibly survived such an event. Ron Wyatt found at geological formation in the mountains of Ararat of petrified wood in the shape of a boat having the same length as described of the Ark in the Bible; https://i.pinimg.com/originals/55/8a/cb/558acb1d59f1dab953c3fcaa16cc2670.jpg =====neutrinos warp spacetime inducing gravity===== (1) I have a hunch that for sure electrons (but possibly all matter) gradients backscatter neutrinos into gradients which (increase the vacuum refractive index and) warping spacetime (2) the atmosphere and the lithosphere are converging lenses to radiation including neutrinos I predict that neutrinos induce something similar to the AC Kerr effect [the higher the intensity, the higher vacuum refractive index induced]. f this is true, then the vacuum refractive index is a transcendent function of neutrino radiation intensity. In other words, the vacuum refractive index necessarily changes according to altitude. Light travels slower in higher refractive index i.e. TIME DILATION according to altitude! FYI, if material bodies (and their radiations and atmospheres) are a converging radiation Luneberg lens, the vacuum refractive index becomes itself stratified as a converging Luneberg lens!; i.e. curvature of light in outer space around objects such as the Sun, solar system, galaxy, galaxy clusters etc. We will need to express the structure of matter; and to expand on Randel's orbitosphere in terms of electromagnetism, I claim the orbitosphere is a Kerr-induced self-focusing refraction curvature. One of the results being that as the vacuum refractive index increases, the Bohr radius shrinks [metaphor; imagine an electron orbiting an atom at a particular velocity and orbital frequency, if you slow the velocity (by increasing the refractive index) the orbit length would have to shrink to maintain the same orbital frequency] i.e. LENGTH CONTRACTION according to altitude (i.e. according to N radiation intensity). https://brilliantlightpower.com/book-download-and-streaming/ as mass travels into higher vacuum refractive index, the mass of matter shrinks, but energy is conserved so the mass energy transforms into kinetic energy; in other words, there is gravity http://www.newtonphysics.on.ca/gravity/index.html =====thrust; artificial gravity; tractor beam; warp drive; photon torpedoes; through longitudinal radiation===== I predict that longitudinal radiation can be used to create thrust, artificial gravity, tractor beams, a warp drive, and photon torpedoes. ====Sodom Brimstone==== With respects to the Divine, the spirits/angels/gods are the person of the Divine. That is simply how a monism/pantheism works. Even we are part of the Divine. So in a sense, we also are gods. Anyway, the bible says; "and the gods said, let us make man in our image" The Divine has no image. So, we cannot be made in the image of the Divine. But we can be made in the image of the gods. Another thing to point out is; functionally speaking, there is no difference between the gods and advanced extraterrestrials. (Ron Wyatt is the original discoverer) https://commons.wikimedia.org/wiki/File:Sodom.jpg Locations identified on the satellite map on the west coast of the Dead Sea have millions of high purity (98% pure) sulfur balls with burn rings embedded in what looks like the ashen remains of cities. The picture on the bottom right is in the location identified on the map as Gomorrah. Spectra Chem Analytical of New Zealand, and Galbrath Lab of Texas; Two independent laboratories have tested the sulfur balls and sulfur ash determining their composition. At least three different groups have surveyed the sites taking samples, and two of those groups have created videos. Here is a video from one of them; http://www.youtube.com/watch?v=FwTVFk1HK3Y It should be noted; (1) volcanic activity turns sulfur into a gas, (2) meteoroids contain only small amounts of sulfur, (3) geothermal activity creates sulfur of no more than 40% purity, (4) a natural gas explosion wouldn't explain the purity of the sulfur balls, and (5) bacteria wouldn't explain the burn rings on the sulfur balls nor the ashen remains. An alternative possibility is that the pure sulfur fire balls were created and used as military munitions in warfare. However, there is no record of using such munitions in warfare. It should be noted that the cities are completely destroyed with even the structural material and stones having been turned into ash. It would take far less sulfur to simply kill the people; turning all of the structural material and stones into ash is militarily unfeasible. Given that the pure sulfur fire balls and ashen remains are not known to be created by any volcanic, meteoric, geothermal, natural gas, or bacterial activity, and given that it is historically unprecedented to use pure sulfur fire balls as munitions and militarily unfeasible to turn all the structural material and stones of the cities into ash, and given that there are records claiming the destruction of Sodom and Gomorrah was by the hand of the person of the Divine, it therefore suggests the existence of the fact that this is the remains of Sodom and Gomorrah, the destruction of which was a teleological interaction of the spirits/angels/gods or person of the Divine with man. ====Neanderthal violence==== Correlation of evidence of Neanderthal violence with Scriptural History http://www.donsmaps.com/images4/neanderthalsapiens.jpg The first reconstruction of a complete Neanderthal skeleton in 2005 has revealed more accurately the similarities and differences between us (far right) and them. The reconstruction makes clear their larger, bell-like chest cavity and wider pelvis. They are physically larger (both taller and bigger than humans), with stronger muscles, larger nose hole and eye sockets, as well as a larger brain cavity. [6] Neanderthal dental enamel hypoplasia found in 75% of individuals and all those particularly aged, suggests they suffered from nutritional deficiencies. Neanderthal practiced cannibalism or ritual defleshing. Neanderthals seemed to suffer a high frequency of fractures, especially common on the ribs, the femur, fibulae, spine, and skull; as well as from trauma such as stab wounds and blows to the head; suggesting a high level of physical violence. "Consequently Jehovah saw that the badness of man was abundant in the earth and every inclination of the thoughts of his heart was only bad all the time. And Jehovah felt regrets that he had made men in the earth, and he felt hurt at his heart. So Jehovah said: “I am going to wipe men whom I have created off the surface of the ground, from man to domestic animal, to moving animal and to flying creature of the heavens, because I do regret that I have made them." (Genesis 6:1-2, 4-7) "In the six hundredth year of Noah’s life, in the second month, on the seventeenth day of the month, on this day all the springs of the vast watery deep were broken open and the floodgates of the heavens were opened. And the downpour upon the earth went on for forty days and forty nights." (Genesis 7:11-12) “Second month.” Following the Exodus from Egypt, when Jehovah gave the Israelites the sacred calendar, this became the eighth month, known as Bul, corresponding to the latter half of October and first half of November. - New World Translation Footnote Genesis 7:11 The global flood which killed all but eight humanoids is said to have occurred on the same dating associated with the Festival of the Dead, for which the European calendar marks the celebrations of All Hollows Eve, and All Souls' Day ====Confusion after the Flood==== Correlation of linguistics and Scriptural History. After the flood a Cushite named Nimrod rebelled against Jehovah; creating cities (Jehovah commanded everyone to spread out). He is called a "king". A king is ruler of a kin (Cushites) which has a kingdom (in this case Summeria; was the first after the flood). Akkadians called Cushites "Summerians" which translates as "black headed people". As a punishment Jehovah confused their languages! Africa has '''more than''' 2000 languages. Where as Europe and Asia only have less then 200 each. Brown people (Cushites) have a hard time speaking simple English, instead they speak Ebonics. It seems that Jehovah confused their languages. Like the Tao Te Ching suggests; 'it seems that rural living is best for mankind'. ====Exodus==== https://www.youtube.com/watch?v=DqLsYonjvRY https://www.youtube.com/watch?v=rsn_HqSxkDg ====Coconut is the tree of life==== The mitochondria oxidizes for energy production whereas the cell body ferments for energy production; the oxidization is 20 times more efficient than fermentation. The mitochondria also control many crucial aspects of cell regulation, including cell death. When the mitochondria are down regulated, or most of the energy of the cell is produced from cell body fermentation, then not only is their reduced energy, the mitochondria no longer have the ability to kill the cell. Cancer is run away cell body fermentation where the mitochondria can't kill the cell. Coconut has medium chain triglycerides such as lauric acid which are antibacterial, antifungal, and pro-mitochondrial. In other words, there is considerable evidence that extended life is impossible without coconut. ====Serpent hind legs==== Moses claimed that the serpent was cursed to go about on it's belly... presumably instead of walking on legs. ancient fossils prove that serpents had hind legs. If I am not mistaken the theory of evolution claimed in the past that the serpent was first and then developed legs on land creating the lizards. But the serpent only had hind legs! (so how did Moses 'know' this???). {{Collapsible END}} :The above request [https://en.wikiversity.org/w/index.php?title=Wikiversity:Request_custodian_action&diff=next&oldid=2723526 was added in August].

I did a preliminary search (as noted in my first comment), but I don't see something so egregious as to require an indef block or any attempts to correct behavior. I've never interacted with this user prior to this thread and since it's been posted, he seems reasonable enough, so I'm disinclined to think that he's here for purely disruptive purposes or just refuses to abide by basic norms. Additionally, while issues at other wikis can be a minor factor in assessing if someone should be blocked here, it's pretty weak evidence and either way, he's not blocked on any WMF wikis, so I'm not seeing a persistent pattern of cross-wiki disruption. I just need something more to go on here to even understand why this was posted at all. :It's unfortunate, but sometimes it happens that two editors for whatever reason clash and neither is necessarily in the wrong or so in the wrong that it requires that one of them be forced to not participate. My suspicion is that's what's happening here and maybe just generally trying to avoid conflict is the best solution. —[[User:Koavf|Justin (<span style="color:grey">ko'''a'''vf</span>)]]<span style="color:red">❤[[User talk:Koavf|T]]☮[[Special:Contributions/Koavf|C]]☺[[Special:Emailuser/Koavf|M]]☯</span> 09:20, 7 November 2025 (UTC) :: Can you please explain how his above "No kidding let me rephrase that: Please be serious" is a remotely acceptable/productive response?

That language is extremely vague and requires heavy interpretation, filling in of detail. I did fill in the detail. The page does not have the status of a policy, only of a guideline. But then, being a guideline (overridable quasi-policy), it allows leeway, something of an administrative discretion. So if you are asking for a formally approved ''policy'', tough luck, and tough luck doing any curatorial work in the English Wikiversity. If you are content with a ''guideline'' and with interpreting the language "learning outcomes are scarce" in the sense of "learning outcomes for people other than the page creator are scarce" and adding further detail, then I think there is a good rationale for moving the very likely inaccurate, possibly incoherent pages created by an editor with not even a superficial demonstrated understanding of quantum mechanics out of mainspace. Sure enough, learning outcomes from Marshallsumter's incoherent prank-pages is not necessarily "scarce" either since one can learn something from his incoherent collections of quotations, so there is another layer of non-literal interpretation required, in the direction of "things have to make sense", perhaps "pages have to show minimum coherence". But even if you move these pages out of mainspace, the obvious troll Harold Foppele is going to continue the disruption. Indef is the right intervention. Alright.

Fontaine and Hurley extended this result, discovering a formula for the reciprocal of a regular polygon chord derived geometrically from the chord's star polygon. We observe that these findings in plane geometry apply more generally, to polytopes of any dimensionality. Fontaine and Hurley's geometric procedure for finding the reciprocals of the chords of a regular polygon from their star polygons also finds the rotational geodesics of any polytope of any dimensionality.</blockquote> == Introduction == Steinbach discovered the Diagonal Product Formula and the Golden Fields family of ratios of diagonal to side in the regular polygons. He showed how this family extends beyond the pentagon {5} with its well-known golden bisection proportional to 𝜙, finding that the heptagon {7} has an analogous trisection, the nonagon {9} has an analogous quadrasection, and the hendecagon {11} has an analogous pentasection, an extended family of golden proportions with quasiperiodic properties. Kappraff and Adamson extended these findings in plane geometry to a theory of Generalized Fibonacci Sequences, showing that the Golden Fields not only do not end with the hendecagon, they form an infinite number of periodic trajectories when operated on by the Mandelbrot operator. They found a relation between the edges of star polygons and dynamical systems in the state of chaos, revealing a connection between chaos theory, number, and rotations in Coxeter Euclidean geometry. Fontaine and Hurley examined Steinbach's finding that the length of each chord of a regular polygon is both the product of two chords and the sum of a set of smaller chords, so that in rotations to add is to multiply. They illustrated Steinbach's sets of additive chords lying parallel to each other in the plane (pointing in the same direction), and by applying Steinbach's formula more generally they found another summation relation of signed parallel chords (pointing in opposite directions) which relates each chord length to its reciprocal, and relates the summation to a distinct star polygon rotation. We examine these remarkable findings (which stem from study of the chords of humble regular polygons) in higher-dimensional spaces, specifically in the chords, polygons and rotations of the [[120-cell]], the largest four-dimensional regular convex polytope. == Visualizing the 120-cell == {| class="wikitable floatright" width="400" |style="vertical-align:top"|[[File:120-cell.gif|200px]]<br>Orthographic projection of the 600-point 120-cell <small><math>\{5,3,3\}</math></small> performing a [[W:SO(4)#Geometry of 4D rotations|simple rotation]].{{Sfn|Hise|2011|loc=File:120-cell.gif|ps=; "Created by Jason Hise with Maya and Macromedia Fireworks.

Therefore even though it is translucent, only its outer surface is visible. The complex interior parts of the 120-cell, all its inscribed 5-cells, 16-cells, 8-cells, 24-cells, 600-cells and its much larger inventory of polyhedra, are completely invisible in this view, as none of their edges are rendered at all. |style="vertical-align:top"|[[File:Ortho solid 016-uniform polychoron p33-t0.png|200px]]<br>Orthographic projection of the 600-point [[W:Great grand stellated 120-cell|great grand stellated 120-cell]] <small><math>\{\tfrac{5}{2},3,3\}</math></small>.{{Sfn|Ruen: Great grand stellated 120-cell|2007}} The 120-cell is its convex hull. The projection to the left renders only the 120-cell's shortest chord, its 1200 edges. The projection above also renders only one of the 120-cell's 30 chords, the edges of its 120 inscribed regular 5-cells. The 120-cell itself (the convex hull) is invisible in this view, as its edges are not rendered. |} [[120-cell#Geometry|The 120-cell is the maximally complex regular 4-polytope]], containing inscribed instances of every regular 1-, 2-, 3-, and 4-polytope, except the regular polygons of more than {15} sides. The 120-cell is the convex hull of a regular [[120-cell#Relationships among interior polytopes|compound of each of the 6 regular convex 4-polytopes]]. They are the [[5-cell|5-point (5-cell) 4-simplex]], the [[16-cell|8-point (16-cell) 4-orthoplex]], the [[W:Tesseract|16-point (8-cell) tesseract]], the [[24-cell|24-point (24-cell)]], the [[600-cell|120-point (600-cell)]], and the [[120-cell|600-point (120-cell)]]. The 120-cell is the convex hull of a compound of 120 disjoint regular 5-cells, of 75 disjoint 16-cells, of 25 disjoint 24-cells, and of 5 disjoint 600-cells. The 120-cell contains an even larger inventory of irregular polytopes, created by the intersection of multiple instances of these component regular 4-polytopes. Many are quite unexpected, because they do not occur as components of any regular polytope smaller than the 120-cell. As just one example among the [[120-cell#Concentric hulls|sections of the 120-cell]], there is an irregular 24-point polyhedron with 16 triangle faces and 4 nonagon {9} faces.{{Sfn|Moxness|}} Most renderings of the 120-cell, like the rotating projection here, only illustrate its outer surface, which is a honeycomb of face-bonded dodecahedral cells. Only the objects in its 3-dimensional surface are rendered, namely the 120 dodecahedra, their pentagon faces, and their edges. Although the 120-cell has chords of 30 distinct lengths, in this kind of simplified rendering only the 120-cell's own edges (its shortest chord) are shown. Its 29 interior chords, the edges of objects in the interior of the 120-cell, are not rendered, so interior objects are not visible at all. Visualizing the complete interior of the 600-vertex 120-cell in a single image is impractical because of its complexity. Only four 120-cell edges are incident at each vertex, but [[120-cell#Chords|600 chords (of all 30 lengths)]] are incident at ''each'' vertex. == Compounds in the 120-cell == The 8-point (16-cell), not the 5-point (5-cell), is the smallest building block; it compounds to every larger regular 4-polytope. The 5-point (5-cell) does compound to the 600-point (120-cell), but it does not fit into any smaller regular 4-polytope. The 8-point (16-cell) compounds by 2 in the 16-point (8-cell), and by 3 in the 24-point (24-cell). The 16-point (8-cell) compounds in the 24-point (24-cell) by 3 non-disjoint instances of itself, with each of the 24 vertices shared by two 16-point (8-cells). The 24-point (24-cell) compounds by 5 disjoint instances of itself in the 120-point (600-cell), and the 120-point (600-cell) compounds by 5 disjoint instances of itself in the 600-point (120-cell). The 24-point (24-cell) also compounds by <math>5^2</math> non-disjoint instances of itself in the 120-point (600-cell); it compounds in 5 disjoint instances of itself, 10 (not 5) different ways. Whichever set of 5 disjoint 24-point (24-cells) are assembled, the resulting 120-point (600-cell) contains 25 distinct 24-point (24-cells), not just 5 (or 10). This implies that 15 disjoint 8-point (16-cells) will construct a 120-point (600-cell), which will contain 75 distinct 8-point (16-cells). The 600-point (120-cell) is 5 disjoint 120-point (600-cells), just 2 different ways (not 5 or 10 ways), so it is 10 distinct 120-point (600-cells). This implies that the 8-point (16-cell) compounds by 3 times <math>5^2</math> (75) disjoint instances of itself in the 600-point (120-cell), which contains <math>3^2</math> times <math>5^2</math> (225) distinct instances of the 24-point (24-cell), and <math>3^3</math> times <math>5^2</math> (675) distinct instances of the 8-point (16-cell). These facts were discovered painstakingly by various researchers, and no one has found a general rule governing subsumption relations among regular polytopes. The reasons for some of their numeric incidence relations are far from obvious. [[W:Pieter Hendrik Schoute|Schoute]] was the first to see that the 120-point (600-cell) is a compound of 5 24-point (24-cells) ''10 different ways'', and after he saw it a hundred years lapsed until Denney, Hooker, Johnson, Robinson, Butler & Claiborne proved his result, and showed why.{{Sfn|Denney, Hooker, Johnson, Robinson, Butler & Claiborne|2020|loc=''The geometry of H4 polytopes''}} So much for the compounds of 16-cells. The 120-cell is also the convex hull of the compound of 120 disjoint regular 5-cells. That stellated compound (without its convex hull of 120-cell edges) is the [[w:Great_grand_stellated_120-cell|great grand stellated 120-cell]] illustrated above, the final regular [[W:Stellation|stellation]] of the 120-cell, and the only [[W:Schläfli-Hess polychoron|regular star 4-polytope]] to have the 120-cell for its convex hull. The edges of the great grand stellated 120-cell are <math>\phi^6</math> as long as those of its 120-cell [[W:List of polyhedral stellations#Stellation process|stellation core]] deep inside. The compound of 120 disjoint 5-point (5-cells) can be seen to be equivalent to the compound of 5 disjoint 120-point (600-cells), as follows. Beginning with a single 120-point (600-cell), expand each vertex into a regular 5-cell, by adding 4 new equidistant vertices, such that the 5 vertices form a regular 5-cell inscribed in the 3-sphere. The 120 5-cells are disjoint, and the 600 vertices form 5 disjoint 120-point (600-cells): a 120-cell. == Thirty distinguished distances == The 30 numbers listed in the table are all-important in Euclidean geometry. A case can be made on symmetry grounds that their squares are the 30 most important numbers between 0 and 4. The 30 rows of the table are the 30 distinct [[120-cell#Geodesic rectangles|chord lengths of the unit-radius 120-cell]], the largest regular convex 4-polytope. Since the 120-cell subsumes all smaller regular polytopes, its 30 chords are the complete chord set of all the regular polytopes that can be constructed in the first four dimensions of Euclidean space, except for regular polygons of more than 15 sides. {| class="wikitable" style="white-space:nowrap;text-align:center" !rowspan=2|<math>c_t</math> !rowspan=2|arc

regular polytopes == In 2-space we have the regular 8-point octagon, in 3-space the regular 8-point cube, and in 4-space the regular 8-point [[16-cell]]. A planar octagon with rigid edges of unit length has chords of length: :<math>r_1=1,r_2=\sqrt{2+\sqrt{2}} \approx 1.84776,r_3=1+\sqrt{2} \approx 2.41421,r_4=\sqrt{4 + \sqrt{8}} \approx 2.61313</math> The chord ratio <math>r_3=1+\sqrt{2}</math> is a geometrical proportion, the [[W:Silver ratio|silver ratio]]. Fontaine and Hurley's procedure for obtaining the reciprocal of a chord tells us that: :<math>r_3-r_1-r_1=1/r_3 \approx 0.41421</math> Note that <math>1/r_3=\sqrt{2}-1=r_3-2</math>. If we embed this planar octagon in 3-space, we can make it skew, repositioning its vertices so that each is one unit-edge length distant from three others instead of two others, at the vertices of a unit-edge cube with chords of length: :<math>r_1=1, r_2=\sqrt{2}, r_3=\sqrt{3}, r_4=\sqrt{2}</math> If we embed this cube in 4-space, we can skew it some more, repositioning its vertices so that each is one unit-edge length distant from six others instead of three others, at the vertices of a unit-edge 4-polytope with chords of length: :<math>r_1=1,r_2=1,r_3=1,r_4=\sqrt{2}</math> All of its chords except its long diameters are the same unit length as its edge. In fact they are its 24 edges, and it is a 16-cell of radius <small><math>1/\sqrt{2}</math></small>. [[File:octagon16cell.png|thumb|Orthogonal projection of a regular 16-cell to the [[16-cell#Projections|B<sub>4</sub> Coxeter plane]]. Only its edges are shown; its long diameter chords are not drawn. All 24 edges are the same length. Only the edges of the two disjoint squares lie parallel to the projection plane, in completely orthogonal central planes.]] The [[16-cell]] is the [[W:Regular convex 4-polytope|regular convex 4-polytope]] with [[W:Schläfli symbol|Schläfli symbol]] {3,3,4}. It has 8 vertices, 24 edges, 32 equilateral triangle faces, and 16 regular tetrahedron cells. It is the [[16-cell#Octahedral dipyramid|four-dimensional analogue of the octahedron]], and each of its four orthogonal central hyperplanes is an octahedron. The only planar regular polygons found in the 16-cell are face triangles and central plane squares, but the 16-cell also contains a regular skew octagon, its [[W:Petrie polygon|Petrie polygon]]. The chords of this regular octagon, which lies skew in 4-space, are those given above for the 16-cell, as opposed to those for the cube or the regular octagon in the plane. The 16-cell is a construct of 3 Petrie octagons which share the same 8 vertices but have disjoint sets of 8 edges each. The regular octad has higher symmetry in 4-space than it does in 2-space. The 16-cell is the 4-orthoplex, the simplest regular 4-polytope after the [[5-cell|4-simplex]]. All the larger regular 4-polytopes, including the 120-cell, are compounds of the 16-cell. The regular octagon exhibits this high symmetry only when embedded in 4-space at the vertices of the 16-cell. The 16-cell constitutes an [[W:Orthonormal basis|orthonormal basis]] for the choice of a 4-dimensional Cartesian reference frame, because its vertices define four orthogonal axes. The eight vertices of a unit-radius 16-cell are (±1, 0, 0, 0), (0, ±1, 0, 0), (0, 0, ±1, 0), (0, 0, 0, ±1). All vertices are connected by <small><math>\sqrt{2}</math></small> edges except opposite pairs. The vertex coordinates of the 16-cell form 6 central squares lying in 6 pairwise [[W:Orthogonal|orthogonal]] coordinate planes. Great squares in ''opposite'' planes that do not share an axis (e.g. in the ''xy'' and ''wz'' planes) are completely disjoint (they do not intersect at any vertices). These planes are [[W:Completely orthogonal|completely orthogonal]].{{Efn|name=Six orthogonal planes of the Cartesian basis}} Since this unit-radius coordinate system is convenient, let us derive the unit-radius 16-cell by skewing a unit-radius planar octagon, which has chords of length: :<math>r_1=\sqrt{2-\sqrt{2}} \approx 0.76537,r_2=\sqrt{2},r_3=\sqrt{2+\sqrt{2}} \approx 1.84776,r_4=2</math> We will need a planar octagon with rigid <math>r_2</math> chords, rather than one with rigid <math>r_1</math> edges. The octagon's <math>r_2</math> chords form two disjoint squares, which we can reposition in 3-space to form a cube by making them parallel, and in 4-space to form a 16-cell by making them completely orthogonal. [[W:Rotations in 4-dimensional Euclidean space|Rotations in 4-dimensional Euclidean space]] can be seen as the composition of two 2-dimensional rotations in completely orthogonal planes. The general rotation in 4-space is a double rotation in pairs of completely orthogonal planes. Two completely orthogonal planes are called invariant planes of the rotation when all points in the plane rotate on circles that remain in the plane, even as the whole plane tilts sideways (like a coin flipping) into another plane. The two completely orthogonal rotations of each plane (like a wheel, and like a coin flipping) are simultaneous but independent, in that they are not geometrically constrained to turn at the same rate. However, the most circular kind of rotation (as opposed to an elliptical double rotation of a rigid spherical object) occurs when the invariant planes do rotate through the same angle in the same time interval. Such equi-angled double rotations are called [[w:SO(4)#Isoclinic_rotations|isoclinic]], also [[w:William_Kingdon_Clifford|Clifford]] displacements. The 16-cell is the simplest possible frame in which to [[16-cell#Rotations|observe 4-dimensional rotations]] because its characteristic isoclinic rotations feature a single pair of invariant rotation planes. In the 16-cell an isoclinic rotation by 90° in any pair of invariant completely orthogonal square central planes takes every square central plane to its completely orthogonal square central plane in a twisting displacment, as they tilt sideways 90° into each other's plane while rotating 90° internally. All the vertices move at once on separate circular [[w:Geodesic|geodesics]], displaced 90° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. When the 90° isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 90°, but from the new orientation in a direction orthogonal to its first 90° displacement. After 360° of rotation each vertex reaches its antipodal position. The trajectory of each vertex over each 90° isoclinic rotational displacement is a one-eighth segment of its geodesic orbit. Its entire orbit traces a circular helix in 4-space, and also traces a great circle twice in one of the two moving invariant rotation planes. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once and returns to its original position, and the 16-cell returns to its original orientation. == Hypercubes == The long diameter of the unit-edge [[W:Hypercube|hypercube]] of dimension <small><math>n</math></small> is <small><math>\sqrt{n}</math></small>, so the unit-edge [[w:Tesseract|4-hypercube, the 16-point (8-cell) tesseract,]] has chords: :<math>r_1=\sqrt{1},r_2=\sqrt{2},r_3=\sqrt{3},r_4=\sqrt{4}</math> Uniquely in its 4-dimensional case, the hypercube's edge length equals its radius, like the hexagon. We call such polytopes ''radially equilateral'', because they can be constructed from equilateral triangles which meet at their center, each contributing two radii and an edge. The cuboctahedron and the 24-cell are also radially equilateral. The [[W:Tesseract|tesseract]] is the [[W:Regular convex 4-polytope|regular convex 4-polytope]] with [[W:Schläfli symbol|Schläfli symbol]] {4,3,3}. It has 16 vertices, 32 edges, 24 square faces, and 8 cube cells. It is the four-dimensional analogue of the cube. The tesseract is the [[W:Dual polytope|dual polytope]] of the 16-cell. They have the same Petrie polygon, the regular octagon, but the tesseract contains 2 disjoint instances and 4 distinct instances of the skew octagon. We can construct the tesseract by skewing two planar octagons. Because the tesseract is radially equilateral (unlike the 16-cell), we start with our original octagon of unit-edge length, rather than the octagon of edge length <small><math>\sqrt{2}</math></small> that we needed to build the unit-radius 16-cell. For our tesseract construction we skew each planar octagon into a cube, so we have a compound of two completely orthogonal cubes. Provided the planes were completely orthogonal in 4-space and we skewed them both the same way, the 16 vertices will be the vertices of a tesseract with half of its 32 edges missing. The 16-point tesseract is the convex hull of a compound of two 8-point 16-cells, in exact dimensional analogy to the way the 8-point cube is the convex hull of a [[W:Stellated octahedron|compound of two regular 4-point tetrahedra]]. The [[W:Demihypercube|demihypercubes]] occupy alternate vertices of the hypercubes. The diagonals of the square faces of the unit-radius tesseract are the <small><math>\sqrt{2}</math></small> edges of two unit-radius 16-cells, which are also the edges of the square central planes. Because the tesseract contains two 16-cells in alternate positions it has two sets of 6 orthogonal square central planes. Two angles are required to specify the relationship between two planes in 4-space. Pairs of planes within each 16-cell are 90° apart in one angle, and either 0° or 90° apart in the other angle. They are 90° apart in both angles if and only if they are completely orthogonal planes, 90° apart by isoclinic rotation, with no vertices in common and their corresponding vertices 180° apart. Otherwise they are 0° apart in one of the angles, 90° apart by simple rotation with their corresponding vertices 90° apart, and they intersect in one axis and lie in a common 3-dimensional hyperplane.{{Efn|A double rotation in which one of the two angles of rotation is 0°, so that one of the completely orthogonal invariant planes does not rotate, is called a simple rotation. Ordinary rotations observed in a 3-dimensional space are simple rotations.}} A pair of square central planes from alternate 16-cells are 60° apart by isoclinic rotation, with their corresponding vertices 120° apart. The planes are not orthogonal or parallel, so they intersect in a line somewhere, but they have no vertices in common, they have no 3-dimensional hyperplane in common, and they cannot reach each other by simple rotation. Such pairs of objects are called [[W:Clifford parallel|Clifford parallel]] because all their corresponding pairs of vertices are the same distance apart, although they are not parallel in the usual sense, because they have a common center. Not only the alternate 16-cells' corresponding square central planes, but also the 16-cells themselves, are Clifford parallel objects. We can rotate the tesseract isoclinically the way we rotated the 16-cell, by 90° in two completely orthogonal invariant square central planes, with the same effect on both alternate 16-cells. In the course of a 720° isoclinic rotation in invariant square central planes each vertex departs from all 8 vertex positions of its 16-cell just once and returns to its original position, but it does not visit the vertex positions of the other 16-cell. The skew octagon geodesic orbits of the 16 vertices are disjoint circular helixes, and those 16 circular helixes are Clifford parallel objects. == The 24-cell == In 2-space we have the radially equilateral 6-point hexagon. In 3-space we have the radially equilateral 12-point cuboctahedron, with 4 hexagonal central planes. In 4-space we have the radially equilateral 24-point 24-cell, with 4 cuboctahedral central hyperplanes and 16 hexagonal central planes. Great hexagons are a rounder choice than great squares for the invariant rotation planes in which to rotate a 4-polytope isoclinically. The complete hexagonal isoclinic revolution requires 720° like the square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 90° each. ... == The 600-cell == ... == Finally the 120-cell == ... == Conclusions == Fontaine and Hurley's discovery is more than a formula for the reciprocal of a regular ''n''-polygon diagonal. It also yields the discrete sequence of isocline chords of the distinct isoclinic rotation characteristic of a ''d''-dimensional regular polytope. The characteristic rotational chord sequence of the ''d''-polytope can be represented geometrically in two dimensions on a distinct star polygon, but it lies on a geodesic circle through ''d''-dimensional space. Fontaine and Hurley discovered the geodesic topology of polytopes generally. Their procedure will reveal the geodesics of arbitrary non-uniform polytopes, since it can be applied to a polytope of any dimensionality and irregularity, by first fitting the polytope to the smallest regular polygon whose chords include its chords. Fontaine and Hurley's discovery of a chordal formula for isoclinic rotations closes the circuit on Kappraff and Adamson's discovery of a rotational connection between dynamical systems, Steinbach's golden fields, and Coxeter's Euclidean geometry of ''n'' dimensions. Application of the Fontaine and Hurley procedure in higher-dimensional spaces demonstrates why the connection exists: because polytope sequences generally, from Steinbach's golden polygon chord sequences, to chord sequences in isoclinic rotation helixes, to subsumption relations in the sequence of regular 4-polytopes, arise as expressions of the reflections and rotations of distinct Coxeter symmetry groups, when those various groups interact. == Appendix: Sequence of regular 4-polytopes == {{Regular convex 4-polytopes|wiki=W:|columns=7}} == Notes == {{Notelist}} == Citations == {{Reflist}} == References == {{Refbegin}} * {{Cite journal | last=Steinbach | first=Peter | year=1997 | title=Golden fields: A case for the Heptagon | journal=Mathematics Magazine | volume=70 | issue=Feb 1997 | pages=22–31 | doi=10.1080/0025570X.1997.11996494 | jstor=2691048 | ref={{SfnRef|Steinbach|1997}} }} * {{Cite journal | last=Steinbach | first=Peter | year=2000 | title=Sections Beyond Golden| journal=Bridges: Mathematical Connections in Art, Music and Science | issue=2000 | pages=35-44 | url=https://archive.bridgesmathart.org/2000/bridges2000-35.pdf | ref={{SfnRef|Steinbach|2000}}}} * {{Cite journal | last1=Kappraff | first1=Jay | last2=Jablan | first2=Slavik | last3=Adamson | first3=Gary | last4=Sazdanovich | first4=Radmila | year=2004 | title=Golden Fields, Generalized Fibonacci Sequences, and Chaotic Matrices | journal=Forma | volume=19 | pages=367-387 | url=https://archive.bridgesmathart.org/2005/bridges2005-369.pdf | ref={{SfnRef|Kappraff, Jablan, Adamson & Sazdanovich|2004}} }} * {{Cite journal | last1=Kappraff | first1=Jay | last2=Adamson | first2=Gary | year=2004 | title=Polygons and Chaos | journal=Dynamical Systems and Geometric Theories | url=https://archive.bridgesmathart.org/2001/bridges2001-67.pdf | ref={{SfnRef|Kappraff & Adamson|2004}} }} * {{Cite journal | last1=Fontaine | first1=Anne | last2=Hurley | first2=Susan | year=2006 | title=Proof by Picture: Products and Reciprocals of Diagonal Length Ratios in the Regular Polygon | journal=Forum Geometricorum | volume=6 | pages=97-101 | url=https://scispace.com/pdf/proof-by-picture-products-and-reciprocals-of-diagonal-length-1aian8mgp9.pdf }} {{Refend}} nzburl1xv17d1tn263vou1vmrky0gkv 2809751 2809748 2026-05-16T20:53:02Z Dc.samizdat 2856930 /* The 8-point regular polytopes */ 2809751 wikitext text/x-wiki {{align|center|David Brooks Christie}} {{align|center|dc@samizdat.org}} {{align|center|Draft in progress}} {{align|center|January 2026 - April 2026}} <blockquote>Steinbach discovered the formula for the ratios of diagonal to side in the regular polygons. Fontaine and Hurley extended this result, discovering a formula for the reciprocal of a regular polygon chord derived geometrically from the chord's star polygon. We observe that these findings in plane geometry apply more generally, to polytopes of any dimensionality. Fontaine and Hurley's geometric procedure for finding the reciprocals of the chords of a regular polygon from their star polygons also finds the rotational geodesics of any polytope of any dimensionality.</blockquote> == Introduction == Steinbach discovered the Diagonal Product Formula and the Golden Fields family of ratios of diagonal to side in the regular polygons. He showed how this family extends beyond the pentagon {5} with its well-known golden bisection proportional to 𝜙, finding that the heptagon {7} has an analogous trisection, the nonagon {9} has an analogous quadrasection, and the hendecagon {11} has an analogous pentasection, an extended family of golden proportions with quasiperiodic properties. Kappraff and Adamson extended these findings in plane geometry to a theory of Generalized Fibonacci Sequences, showing that the Golden Fields not only do not end with the hendecagon, they form an infinite number of periodic trajectories when operated on by the Mandelbrot operator. They found a relation between the edges of star polygons and dynamical systems in the state of chaos, revealing a connection between chaos theory, number, and rotations in Coxeter Euclidean geometry. Fontaine and Hurley examined Steinbach's finding that the length of each chord of a regular polygon is both the product of two chords and the sum of a set of smaller chords, so that in rotations to add is to multiply. They illustrated Steinbach's sets of additive chords lying parallel to each other in the plane (pointing in the same direction), and by applying Steinbach's formula more generally they found another summation relation of signed parallel chords (pointing in opposite directions) which relates each chord length to its reciprocal, and relates the summation to a distinct star polygon rotation. We examine these remarkable findings (which stem from study of the chords of humble regular polygons) in higher-dimensional spaces, specifically in the chords, polygons and rotations of the [[120-cell]], the largest four-dimensional regular convex polytope. == Visualizing the 120-cell == {| class="wikitable floatright" width="400" |style="vertical-align:top"|[[File:120-cell.gif|200px]]<br>Orthographic projection of the 600-point 120-cell <small><math>\{5,3,3\}</math></small> performing a [[W:SO(4)#Geometry of 4D rotations|simple rotation]].{{Sfn|Hise|2011|loc=File:120-cell.gif|ps=; "Created by Jason Hise with Maya and Macromedia Fireworks.

Therefore even though it is translucent, only its outer surface is visible. The complex interior parts of the 120-cell, all its inscribed 5-cells, 16-cells, 8-cells, 24-cells, 600-cells and its much larger inventory of polyhedra, are completely invisible in this view, as none of their edges are rendered at all. |style="vertical-align:top"|[[File:Ortho solid 016-uniform polychoron p33-t0.png|200px]]<br>Orthographic projection of the 600-point [[W:Great grand stellated 120-cell|great grand stellated 120-cell]] <small><math>\{\tfrac{5}{2},3,3\}</math></small>.{{Sfn|Ruen: Great grand stellated 120-cell|2007}} The 120-cell is its convex hull.

The 120-cell is the convex hull of a regular [[120-cell#Relationships among interior polytopes|compound of each of the 6 regular convex 4-polytopes]]. They are the [[5-cell|5-point (5-cell) 4-simplex]], the [[16-cell|8-point (16-cell) 4-orthoplex]], the [[W:Tesseract|16-point (8-cell) tesseract]], the [[24-cell|24-point (24-cell)]], the [[600-cell|120-point (600-cell)]], and the [[120-cell|600-point (120-cell)]]. The 120-cell is the convex hull of a compound of 120 disjoint regular 5-cells, of 75 disjoint 16-cells, of 25 disjoint 24-cells, and of 5 disjoint 600-cells. The 120-cell contains an even larger inventory of irregular polytopes, created by the intersection of multiple instances of these component regular 4-polytopes. Many are quite unexpected, because they do not occur as components of any regular polytope smaller than the 120-cell. As just one example among the [[120-cell#Concentric hulls|sections of the 120-cell]], there is an irregular 24-point polyhedron with 16 triangle faces and 4 nonagon {9} faces.{{Sfn|Moxness|}} Most renderings of the 120-cell, like the rotating projection here, only illustrate its outer surface, which is a honeycomb of face-bonded dodecahedral cells. Only the objects in its 3-dimensional surface are rendered, namely the 120 dodecahedra, their pentagon faces, and their edges. Although the 120-cell has chords of 30 distinct lengths, in this kind of simplified rendering only the 120-cell's own edges (its shortest chord) are shown. Its 29 interior chords, the edges of objects in the interior of the 120-cell, are not rendered, so interior objects are not visible at all. Visualizing the complete interior of the 600-vertex 120-cell in a single image is impractical because of its complexity. Only four 120-cell edges are incident at each vertex, but [[120-cell#Chords|600 chords (of all 30 lengths)]] are incident at ''each'' vertex. == Compounds in the 120-cell == The 8-point (16-cell), not the 5-point (5-cell), is the smallest building block; it compounds to every larger regular 4-polytope. The 5-point (5-cell) does compound to the 600-point (120-cell), but it does not fit into any smaller regular 4-polytope. The 8-point (16-cell) compounds by 2 in the 16-point (8-cell), and by 3 in the 24-point (24-cell). The 16-point (8-cell) compounds in the 24-point (24-cell) by 3 non-disjoint instances of itself, with each of the 24 vertices shared by two 16-point (8-cells). The 24-point (24-cell) compounds by 5 disjoint instances of itself in the 120-point (600-cell), and the 120-point (600-cell) compounds by 5 disjoint instances of itself in the 600-point (120-cell). The 24-point (24-cell) also compounds by <math>5^2</math> non-disjoint instances of itself in the 120-point (600-cell); it compounds in 5 disjoint instances of itself, 10 (not 5) different ways. Whichever set of 5 disjoint 24-point (24-cells) are assembled, the resulting 120-point (600-cell) contains 25 distinct 24-point (24-cells), not just 5 (or 10). This implies that 15 disjoint 8-point (16-cells) will construct a 120-point (600-cell), which will contain 75 distinct 8-point (16-cells). The 600-point (120-cell) is 5 disjoint 120-point (600-cells), just 2 different ways (not 5 or 10 ways), so it is 10 distinct 120-point (600-cells). This implies that the 8-point (16-cell) compounds by 3 times <math>5^2</math> (75) disjoint instances of itself in the 600-point (120-cell), which contains <math>3^2</math> times <math>5^2</math> (225) distinct instances of the 24-point (24-cell), and <math>3^3</math> times <math>5^2</math> (675) distinct instances of the 8-point (16-cell). These facts were discovered painstakingly by various researchers, and no one has found a general rule governing subsumption relations among regular polytopes. The reasons for some of their numeric incidence relations are far from obvious. [[W:Pieter Hendrik Schoute|Schoute]] was the first to see that the 120-point (600-cell) is a compound of 5 24-point (24-cells) ''10 different ways'', and after he saw it a hundred years lapsed until Denney, Hooker, Johnson, Robinson, Butler & Claiborne proved his result, and showed why.{{Sfn|Denney, Hooker, Johnson, Robinson, Butler & Claiborne|2020|loc=''The geometry of H4 polytopes''}} So much for the compounds of 16-cells. The 120-cell is also the convex hull of the compound of 120 disjoint regular 5-cells. That stellated compound (without its convex hull of 120-cell edges) is the [[w:Great_grand_stellated_120-cell|great grand stellated 120-cell]] illustrated above, the final regular [[W:Stellation|stellation]] of the 120-cell, and the only [[W:Schläfli-Hess polychoron|regular star 4-polytope]] to have the 120-cell for its convex hull. The edges of the great grand stellated 120-cell are <math>\phi^6</math> as long as those of its 120-cell [[W:List of polyhedral stellations#Stellation process|stellation core]] deep inside. The compound of 120 disjoint 5-point (5-cells) can be seen to be equivalent to the compound of 5 disjoint 120-point (600-cells), as follows. Beginning with a single 120-point (600-cell), expand each vertex into a regular 5-cell, by adding 4 new equidistant vertices, such that the 5 vertices form a regular 5-cell inscribed in the 3-sphere. The 120 5-cells are disjoint, and the 600 vertices form 5 disjoint 120-point (600-cells): a 120-cell. == Thirty distinguished distances == The 30 numbers listed in the table are all-important in Euclidean geometry. A case can be made on symmetry grounds that their squares are the 30 most important numbers between 0 and 4. The 30 rows of the table are the 30 distinct [[120-cell#Geodesic rectangles|chord lengths of the unit-radius 120-cell]], the largest regular convex 4-polytope. Since the 120-cell subsumes all smaller regular polytopes, its 30 chords are the complete chord set of all the regular polytopes that can be constructed in the first four dimensions of Euclidean space, except for regular polygons of more than 15 sides. {| class="wikitable" style="white-space:nowrap;text-align:center" !rowspan=2|<math>c_t</math> !rowspan=2|arc

regular polytopes == In 2-space we have the regular 8-point octagon, in 3-space the regular 8-point cube, and in 4-space the regular 8-point [[16-cell]]. A planar octagon with rigid edges of unit length has chords of length: :<math>r_1=1,r_2=\sqrt{2+\sqrt{2}} \approx 1.84776,r_3=1+\sqrt{2} \approx 2.41421,r_4=\sqrt{4 + \sqrt{8}} \approx 2.61313</math> The chord ratio <math>r_3=1+\sqrt{2}</math> is a geometrical proportion, the [[W:Silver ratio|silver ratio]]. Fontaine and Hurley's procedure for obtaining the reciprocal of a chord tells us that: :<math>r_3-r_1-r_1=1/r_3 \approx 0.41421</math> Note that <math>1/r_3=\sqrt{2}-1=r_3-2</math>. If we embed this planar octagon in 3-space, we can make it skew, repositioning its vertices so that each is one unit-edge length distant from three others instead of two others, at the vertices of a unit-edge cube with chords of length: :<math>r_1=1, r_2=\sqrt{2}, r_3=\sqrt{3}, r_4=\sqrt{2}</math> If we embed this cube in 4-space, we can skew it some more, repositioning its vertices so that each is one unit-edge length distant from six others instead of three others, at the vertices of a unit-edge 4-polytope with chords of length: :<math>r_1=1,r_2=1,r_3=1,r_4=\sqrt{2}</math> All of its chords except its long diameters are the same unit length as its edge. In fact they are its 24 edges, and it is a 16-cell of radius <small><math>1/\sqrt{2}</math></small>. [[File:octagon16cell.png|thumb|Orthogonal projection of a regular 16-cell to the [[16-cell#Projections|B<sub>4</sub> Coxeter plane]]. Only its edges are shown; its long diameter chords are not drawn. All 24 edges are the same length. Only the edges of the two disjoint squares lie parallel to the projection plane, in completely orthogonal central planes.]] The [[16-cell]] is the [[W:Regular convex 4-polytope|regular convex 4-polytope]] with [[W:Schläfli symbol|Schläfli symbol]] {3,3,4}. It has 8 vertices, 24 edges, 32 equilateral triangle faces, and 16 regular tetrahedron cells. It is the [[16-cell#Octahedral dipyramid|four-dimensional analogue of the octahedron]], and each of its four orthogonal central hyperplanes is an octahedron. The only planar regular polygons found in the 16-cell are face triangles and central plane squares, but the 16-cell also contains a skew regular octagon, its [[W:Petrie polygon|Petrie polygon]]. The chords of this regular octagon, which lies skew in 4-space, are those given above for the 16-cell, as opposed to those for the cube or the regular octagon in the plane. The 16-cell is a construct of 3 Petrie octagons which share the same 8 vertices but have disjoint sets of 8 edges each. The regular octad has higher symmetry in 4-space than it does in 2-space. The 16-cell is the 4-orthoplex, the simplest regular 4-polytope after the [[5-cell|4-simplex]]. All the larger regular 4-polytopes, including the 120-cell, are compounds of the 16-cell. The regular octagon exhibits this high symmetry only when embedded in 4-space at the vertices of the 16-cell. The 16-cell constitutes an [[W:Orthonormal basis|orthonormal basis]] for the choice of a 4-dimensional Cartesian reference frame, because its vertices define four orthogonal axes. The eight vertices of a unit-radius 16-cell are (±1, 0, 0, 0), (0, ±1, 0, 0), (0, 0, ±1, 0), (0, 0, 0, ±1). All vertices are connected by <small><math>\sqrt{2}</math></small> edges except opposite pairs. The vertex coordinates of the 16-cell form 6 central squares lying in 6 pairwise [[W:Orthogonal|orthogonal]] coordinate planes. Great squares in ''opposite'' planes that do not share an axis (e.g. in the ''xy'' and ''wz'' planes) are completely disjoint (they do not intersect at any vertices). These planes are [[W:Completely orthogonal|completely orthogonal]].{{Efn|name=Six orthogonal planes of the Cartesian basis}} Since this unit-radius coordinate system is convenient, let us derive the unit-radius 16-cell by skewing a unit-radius planar octagon, which has chords of length: :<math>r_1=\sqrt{2-\sqrt{2}} \approx 0.76537,r_2=\sqrt{2},r_3=\sqrt{2+\sqrt{2}} \approx 1.84776,r_4=2</math> We will need a planar octagon with rigid <math>r_2</math> chords, rather than one with rigid <math>r_1</math> edges. The octagon's <math>r_2</math> chords form two disjoint squares, which we can reposition in 3-space to form a cube by making them parallel, and in 4-space to form a 16-cell by making them completely orthogonal. [[W:Rotations in 4-dimensional Euclidean space|Rotations in 4-dimensional Euclidean space]] can be seen as the composition of two 2-dimensional rotations in completely orthogonal planes. The general rotation in 4-space is a double rotation in pairs of completely orthogonal planes. Two completely orthogonal planes are called invariant planes of the rotation when all points in the plane rotate on circles that remain in the plane, even as the whole plane tilts sideways (like a coin flipping) into another plane. The two completely orthogonal rotations of each plane (like a wheel, and like a coin flipping) are simultaneous but independent, in that they are not geometrically constrained to turn at the same rate. However, the most circular kind of rotation (as opposed to an elliptical double rotation of a rigid spherical object) occurs when the invariant planes do rotate through the same angle in the same time interval. Such equi-angled double rotations are called [[w:SO(4)#Isoclinic_rotations|isoclinic]], also [[w:William_Kingdon_Clifford|Clifford]] displacements. The 16-cell is the simplest possible frame in which to [[16-cell#Rotations|observe 4-dimensional rotations]] because its characteristic isoclinic rotations feature a single pair of invariant rotation planes. In the 16-cell an isoclinic rotation by 90° in any pair of invariant completely orthogonal square central planes takes every square central plane to its completely orthogonal square central plane in a twisting displacment, as they tilt sideways 90° into each other's plane while rotating 90° internally. All the vertices move at once on separate circular [[w:Geodesic|geodesics]], displaced 90° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. When the 90° isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 90°, but from the new orientation in a direction orthogonal to its first 90° displacement. After 360° of rotation each vertex reaches its antipodal position. The trajectory of each vertex over each 90° isoclinic rotational displacement is a one-eighth segment of its geodesic orbit. Its entire orbit traces a circular helix in 4-space, and also traces a great circle twice in one of the two moving invariant rotation planes. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once and returns to its original position, and the 16-cell returns to its original orientation. == Hypercubes == The long diameter of the unit-edge [[W:Hypercube|hypercube]] of dimension <small><math>n</math></small> is <small><math>\sqrt{n}</math></small>, so the unit-edge [[w:Tesseract|4-hypercube, the 16-point (8-cell) tesseract,]] has chords: :<math>r_1=\sqrt{1},r_2=\sqrt{2},r_3=\sqrt{3},r_4=\sqrt{4}</math> Uniquely in its 4-dimensional case, the hypercube's edge length equals its radius, like the hexagon. We call such polytopes ''radially equilateral'', because they can be constructed from equilateral triangles which meet at their center, each contributing two radii and an edge. The cuboctahedron and the 24-cell are also radially equilateral. The [[W:Tesseract|tesseract]] is the [[W:Regular convex 4-polytope|regular convex 4-polytope]] with [[W:Schläfli symbol|Schläfli symbol]] {4,3,3}. It has 16 vertices, 32 edges, 24 square faces, and 8 cube cells. It is the four-dimensional analogue of the cube. The tesseract is the [[W:Dual polytope|dual polytope]] of the 16-cell. They have the same Petrie polygon, the regular octagon, but the tesseract contains 2 disjoint instances and 4 distinct instances of the skew octagon. We can construct the tesseract by skewing two planar octagons. Because the tesseract is radially equilateral (unlike the 16-cell), we start with our original octagon of unit-edge length, rather than the octagon of edge length <small><math>\sqrt{2}</math></small> that we needed to build the unit-radius 16-cell. For our tesseract construction we skew each planar octagon into a cube, so we have a compound of two completely orthogonal cubes. Provided the planes were completely orthogonal in 4-space and we skewed them both the same way, the 16 vertices will be the vertices of a tesseract with half of its 32 edges missing. The 16-point tesseract is the convex hull of a compound of two 8-point 16-cells, in exact dimensional analogy to the way the 8-point cube is the convex hull of a [[W:Stellated octahedron|compound of two regular 4-point tetrahedra]]. The [[W:Demihypercube|demihypercubes]] occupy alternate vertices of the hypercubes. The diagonals of the square faces of the unit-radius tesseract are the <small><math>\sqrt{2}</math></small> edges of two unit-radius 16-cells, which are also the edges of the square central planes. Because the tesseract contains two 16-cells in alternate positions it has two sets of 6 orthogonal square central planes. Two angles are required to specify the relationship between two planes in 4-space. Pairs of planes within each 16-cell are 90° apart in one angle, and either 0° or 90° apart in the other angle. They are 90° apart in both angles if and only if they are completely orthogonal planes, 90° apart by isoclinic rotation, with no vertices in common and their corresponding vertices 180° apart. Otherwise they are 0° apart in one of the angles, 90° apart by simple rotation with their corresponding vertices 90° apart, and they intersect in one axis and lie in a common 3-dimensional hyperplane.{{Efn|A double rotation in which one of the two angles of rotation is 0°, so that one of the completely orthogonal invariant planes does not rotate, is called a simple rotation. Ordinary rotations observed in a 3-dimensional space are simple rotations.}} A pair of square central planes from alternate 16-cells are 60° apart by isoclinic rotation, with their corresponding vertices 120° apart. The planes are not orthogonal or parallel, so they intersect in a line somewhere, but they have no vertices in common, they have no 3-dimensional hyperplane in common, and they cannot reach each other by simple rotation. Such pairs of objects are called [[W:Clifford parallel|Clifford parallel]] because all their corresponding pairs of vertices are the same distance apart, although they are not parallel in the usual sense, because they have a common center. Not only the alternate 16-cells' corresponding square central planes, but also the 16-cells themselves, are Clifford parallel objects. We can rotate the tesseract isoclinically the way we rotated the 16-cell, by 90° in two completely orthogonal invariant square central planes, with the same effect on both alternate 16-cells. In the course of a 720° isoclinic rotation in invariant square central planes each vertex departs from all 8 vertex positions of its 16-cell just once and returns to its original position, but it does not visit the vertex positions of the other 16-cell. The skew octagon geodesic orbits of the 16 vertices are disjoint circular helixes, and those 16 circular helixes are Clifford parallel objects. == The 24-cell == In 2-space we have the radially equilateral 6-point hexagon. In 3-space we have the radially equilateral 12-point cuboctahedron, with 4 hexagonal central planes. In 4-space we have the radially equilateral 24-point 24-cell, with 4 cuboctahedral central hyperplanes and 16 hexagonal central planes. Great hexagons are a rounder choice than great squares for the invariant rotation planes in which to rotate a 4-polytope isoclinically. The complete hexagonal isoclinic revolution requires 720° like the square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 90° each. ... == The 600-cell == ... == Finally the 120-cell == ... == Conclusions == Fontaine and Hurley's discovery is more than a formula for the reciprocal of a regular ''n''-polygon diagonal. It also yields the discrete sequence of isocline chords of the distinct isoclinic rotation characteristic of a ''d''-dimensional regular polytope. The characteristic rotational chord sequence of the ''d''-polytope can be represented geometrically in two dimensions on a distinct star polygon, but it lies on a geodesic circle through ''d''-dimensional space. Fontaine and Hurley discovered the geodesic topology of polytopes generally. Their procedure will reveal the geodesics of arbitrary non-uniform polytopes, since it can be applied to a polytope of any dimensionality and irregularity, by first fitting the polytope to the smallest regular polygon whose chords include its chords. Fontaine and Hurley's discovery of a chordal formula for isoclinic rotations closes the circuit on Kappraff and Adamson's discovery of a rotational connection between dynamical systems, Steinbach's golden fields, and Coxeter's Euclidean geometry of ''n'' dimensions. Application of the Fontaine and Hurley procedure in higher-dimensional spaces demonstrates why the connection exists: because polytope sequences generally, from Steinbach's golden polygon chord sequences, to chord sequences in isoclinic rotation helixes, to subsumption relations in the sequence of regular 4-polytopes, arise as expressions of the reflections and rotations of distinct Coxeter symmetry groups, when those various groups interact. == Appendix: Sequence of regular 4-polytopes == {{Regular convex 4-polytopes|wiki=W:|columns=7}} == Notes == {{Notelist}} == Citations == {{Reflist}} == References == {{Refbegin}} * {{Cite journal | last=Steinbach | first=Peter | year=1997 | title=Golden fields: A case for the Heptagon | journal=Mathematics Magazine | volume=70 | issue=Feb 1997 | pages=22–31 | doi=10.1080/0025570X.1997.11996494 | jstor=2691048 | ref={{SfnRef|Steinbach|1997}} }} * {{Cite journal | last=Steinbach | first=Peter | year=2000 | title=Sections Beyond Golden| journal=Bridges: Mathematical Connections in Art, Music and Science | issue=2000 | pages=35-44 | url=https://archive.bridgesmathart.org/2000/bridges2000-35.pdf | ref={{SfnRef|Steinbach|2000}}}} * {{Cite journal | last1=Kappraff | first1=Jay | last2=Jablan | first2=Slavik | last3=Adamson | first3=Gary | last4=Sazdanovich | first4=Radmila | year=2004 | title=Golden Fields, Generalized Fibonacci Sequences, and Chaotic Matrices | journal=Forma | volume=19 | pages=367-387 | url=https://archive.bridgesmathart.org/2005/bridges2005-369.pdf | ref={{SfnRef|Kappraff, Jablan, Adamson & Sazdanovich|2004}} }} * {{Cite journal | last1=Kappraff | first1=Jay | last2=Adamson | first2=Gary | year=2004 | title=Polygons and Chaos | journal=Dynamical Systems and Geometric Theories | url=https://archive.bridgesmathart.org/2001/bridges2001-67.pdf | ref={{SfnRef|Kappraff & Adamson|2004}} }} * {{Cite journal | last1=Fontaine | first1=Anne | last2=Hurley | first2=Susan | year=2006 | title=Proof by Picture: Products and Reciprocals of Diagonal Length Ratios in the Regular Polygon | journal=Forum Geometricorum | volume=6 | pages=97-101 | url=https://scispace.com/pdf/proof-by-picture-products-and-reciprocals-of-diagonal-length-1aian8mgp9.pdf }} {{Refend}} 0k093v3ijo1zdiwl9np4hpljkyi5uza 2809763 2809751 2026-05-16T22:10:34Z Dc.samizdat 2856930 /* The 8-point regular polytopes */ 2809763 wikitext text/x-wiki {{align|center|David Brooks Christie}} {{align|center|dc@samizdat.org}} {{align|center|Draft in progress}} {{align|center|January 2026 - April 2026}} <blockquote>Steinbach discovered the formula for the ratios of diagonal to side in the regular polygons. Fontaine and Hurley extended this result, discovering a formula for the reciprocal of a regular polygon chord derived geometrically from the chord's star polygon. We observe that these findings in plane geometry apply more generally, to polytopes of any dimensionality. Fontaine and Hurley's geometric procedure for finding the reciprocals of the chords of a regular polygon from their star polygons also finds the rotational geodesics of any polytope of any dimensionality.</blockquote> == Introduction == Steinbach discovered the Diagonal Product Formula and the Golden Fields family of ratios of diagonal to side in the regular polygons. He showed how this family extends beyond the pentagon {5} with its well-known golden bisection proportional to 𝜙, finding that the heptagon {7} has an analogous trisection, the nonagon {9} has an analogous quadrasection, and the hendecagon {11} has an analogous pentasection, an extended family of golden proportions with quasiperiodic properties. Kappraff and Adamson extended these findings in plane geometry to a theory of Generalized Fibonacci Sequences, showing that the Golden Fields not only do not end with the hendecagon, they form an infinite number of periodic trajectories when operated on by the Mandelbrot operator. They found a relation between the edges of star polygons and dynamical systems in the state of chaos, revealing a connection between chaos theory, number, and rotations in Coxeter Euclidean geometry. Fontaine and Hurley examined Steinbach's finding that the length of each chord of a regular polygon is both the product of two chords and the sum of a set of smaller chords, so that in rotations to add is to multiply. They illustrated Steinbach's sets of additive chords lying parallel to each other in the plane (pointing in the same direction), and by applying Steinbach's formula more generally they found another summation relation of signed parallel chords (pointing in opposite directions) which relates each chord length to its reciprocal, and relates the summation to a distinct star polygon rotation. We examine these remarkable findings (which stem from study of the chords of humble regular polygons) in higher-dimensional spaces, specifically in the chords, polygons and rotations of the [[120-cell]], the largest four-dimensional regular convex polytope. == Visualizing the 120-cell == {| class="wikitable floatright" width="400" |style="vertical-align:top"|[[File:120-cell.gif|200px]]<br>Orthographic projection of the 600-point 120-cell <small><math>\{5,3,3\}</math></small> performing a [[W:SO(4)#Geometry of 4D rotations|simple rotation]].{{Sfn|Hise|2011|loc=File:120-cell.gif|ps=; "Created by Jason Hise with Maya and Macromedia Fireworks.

Therefore even though it is translucent, only its outer surface is visible. The complex interior parts of the 120-cell, all its inscribed 5-cells, 16-cells, 8-cells, 24-cells, 600-cells and its much larger inventory of polyhedra, are completely invisible in this view, as none of their edges are rendered at all. |style="vertical-align:top"|[[File:Ortho solid 016-uniform polychoron p33-t0.png|200px]]<br>Orthographic projection of the 600-point [[W:Great grand stellated 120-cell|great grand stellated 120-cell]] <small><math>\{\tfrac{5}{2},3,3\}</math></small>.{{Sfn|Ruen: Great grand stellated 120-cell|2007}} The 120-cell is its convex hull.

The 120-cell itself (the convex hull) is invisible in this view, as its edges are not rendered. |} [[120-cell#Geometry|The 120-cell is the maximally complex regular 4-polytope]], containing inscribed instances of every regular 1-, 2-, 3-, and 4-polytope, except the regular polygons of more than {15} sides. The 120-cell is the convex hull of a regular [[120-cell#Relationships among interior polytopes|compound of each of the 6 regular convex 4-polytopes]]. They are the [[5-cell|5-point (5-cell) 4-simplex]], the [[16-cell|8-point (16-cell) 4-orthoplex]], the [[W:Tesseract|16-point (8-cell) tesseract]], the [[24-cell|24-point (24-cell)]], the [[600-cell|120-point (600-cell)]], and the [[120-cell|600-point (120-cell)]]. The 120-cell is the convex hull of a compound of 120 disjoint regular 5-cells, of 75 disjoint 16-cells, of 25 disjoint 24-cells, and of 5 disjoint 600-cells. The 120-cell contains an even larger inventory of irregular polytopes, created by the intersection of multiple instances of these component regular 4-polytopes. Many are quite unexpected, because they do not occur as components of any regular polytope smaller than the 120-cell. As just one example among the [[120-cell#Concentric hulls|sections of the 120-cell]], there is an irregular 24-point polyhedron with 16 triangle faces and 4 nonagon {9} faces.{{Sfn|Moxness|}} Most renderings of the 120-cell, like the rotating projection here, only illustrate its outer surface, which is a honeycomb of face-bonded dodecahedral cells. Only the objects in its 3-dimensional surface are rendered, namely the 120 dodecahedra, their pentagon faces, and their edges. Although the 120-cell has chords of 30 distinct lengths, in this kind of simplified rendering only the 120-cell's own edges (its shortest chord) are shown. Its 29 interior chords, the edges of objects in the interior of the 120-cell, are not rendered, so interior objects are not visible at all. Visualizing the complete interior of the 600-vertex 120-cell in a single image is impractical because of its complexity. Only four 120-cell edges are incident at each vertex, but [[120-cell#Chords|600 chords (of all 30 lengths)]] are incident at ''each'' vertex. == Compounds in the 120-cell == The 8-point (16-cell), not the 5-point (5-cell), is the smallest building block; it compounds to every larger regular 4-polytope. The 5-point (5-cell) does compound to the 600-point (120-cell), but it does not fit into any smaller regular 4-polytope. The 8-point (16-cell) compounds by 2 in the 16-point (8-cell), and by 3 in the 24-point (24-cell). The 16-point (8-cell) compounds in the 24-point (24-cell) by 3 non-disjoint instances of itself, with each of the 24 vertices shared by two 16-point (8-cells). The 24-point (24-cell) compounds by 5 disjoint instances of itself in the 120-point (600-cell), and the 120-point (600-cell) compounds by 5 disjoint instances of itself in the 600-point (120-cell). The 24-point (24-cell) also compounds by <math>5^2</math> non-disjoint instances of itself in the 120-point (600-cell); it compounds in 5 disjoint instances of itself, 10 (not 5) different ways. Whichever set of 5 disjoint 24-point (24-cells) are assembled, the resulting 120-point (600-cell) contains 25 distinct 24-point (24-cells), not just 5 (or 10). This implies that 15 disjoint 8-point (16-cells) will construct a 120-point (600-cell), which will contain 75 distinct 8-point (16-cells). The 600-point (120-cell) is 5 disjoint 120-point (600-cells), just 2 different ways (not 5 or 10 ways), so it is 10 distinct 120-point (600-cells). This implies that the 8-point (16-cell) compounds by 3 times <math>5^2</math> (75) disjoint instances of itself in the 600-point (120-cell), which contains <math>3^2</math> times <math>5^2</math> (225) distinct instances of the 24-point (24-cell), and <math>3^3</math> times <math>5^2</math> (675) distinct instances of the 8-point (16-cell). These facts were discovered painstakingly by various researchers, and no one has found a general rule governing subsumption relations among regular polytopes. The reasons for some of their numeric incidence relations are far from obvious. [[W:Pieter Hendrik Schoute|Schoute]] was the first to see that the 120-point (600-cell) is a compound of 5 24-point (24-cells) ''10 different ways'', and after he saw it a hundred years lapsed until Denney, Hooker, Johnson, Robinson, Butler & Claiborne proved his result, and showed why.{{Sfn|Denney, Hooker, Johnson, Robinson, Butler & Claiborne|2020|loc=''The geometry of H4 polytopes''}} So much for the compounds of 16-cells. The 120-cell is also the convex hull of the compound of 120 disjoint regular 5-cells. That stellated compound (without its convex hull of 120-cell edges) is the [[w:Great_grand_stellated_120-cell|great grand stellated 120-cell]] illustrated above, the final regular [[W:Stellation|stellation]] of the 120-cell, and the only [[W:Schläfli-Hess polychoron|regular star 4-polytope]] to have the 120-cell for its convex hull. The edges of the great grand stellated 120-cell are <math>\phi^6</math> as long as those of its 120-cell [[W:List of polyhedral stellations#Stellation process|stellation core]] deep inside. The compound of 120 disjoint 5-point (5-cells) can be seen to be equivalent to the compound of 5 disjoint 120-point (600-cells), as follows. Beginning with a single 120-point (600-cell), expand each vertex into a regular 5-cell, by adding 4 new equidistant vertices, such that the 5 vertices form a regular 5-cell inscribed in the 3-sphere. The 120 5-cells are disjoint, and the 600 vertices form 5 disjoint 120-point (600-cells): a 120-cell. == Thirty distinguished distances == The 30 numbers listed in the table are all-important in Euclidean geometry. A case can be made on symmetry grounds that their squares are the 30 most important numbers between 0 and 4. The 30 rows of the table are the 30 distinct [[120-cell#Geodesic rectangles|chord lengths of the unit-radius 120-cell]], the largest regular convex 4-polytope. Since the 120-cell subsumes all smaller regular polytopes, its 30 chords are the complete chord set of all the regular polytopes that can be constructed in the first four dimensions of Euclidean space, except for regular polygons of more than 15 sides. {| class="wikitable" style="white-space:nowrap;text-align:center" !rowspan=2|<math>c_t</math> !rowspan=2|arc

regular polytopes == In 2-space we have the regular 8-point octagon, in 3-space the regular 8-point cube, and in 4-space the regular 8-point [[16-cell]]. A planar octagon with rigid edges of unit length has chords of length: :<math>r_1=1,r_2=\sqrt{2+\sqrt{2}} \approx 1.84776,r_3=1+\sqrt{2} \approx 2.41421,r_4=\sqrt{4 + \sqrt{8}} \approx 2.61313</math> The chord ratio <math>r_3=1+\sqrt{2}</math> is a geometrical proportion, the [[W:Silver ratio|silver ratio]]. Fontaine and Hurley's procedure for obtaining the reciprocal of a chord tells us that: :<math>r_3-r_1-r_1=1/r_3 \approx 0.41421</math> Note that <math>1/r_3=\sqrt{2}-1=r_3-2</math>. If we embed this planar octagon in 3-space, we can make it skew, repositioning its vertices so that each is one unit-edge length distant from three others instead of two others, at the vertices of a unit-edge cube with chords of length: :<math>r_1=1, r_2=\sqrt{2}, r_3=\sqrt{3}, r_4=\sqrt{2}</math> If we embed this cube in 4-space, we can skew it some more, repositioning its vertices so that each is one unit-edge length distant from six others instead of three others, at the vertices of a unit-edge 4-polytope with chords of length: :<math>r_1=1,r_2=1,r_3=1,r_4=\sqrt{2}</math> All of its chords except its long diameters are the same unit length as its edge. In fact they are its 24 edges, and it is a 16-cell of radius <small><math>1/\sqrt{2}</math></small>. [[File:octagon16cell.png|thumb|Orthogonal projection of a regular 16-cell to the [[16-cell#Projections|B<sub>4</sub> Coxeter plane]]. Only its edges are shown; its long diameter chords are not drawn. All 24 edges are the same length. Only the edges of the two disjoint squares lie parallel to the projection plane, in completely orthogonal central planes.]] The [[16-cell]] is the [[W:Regular convex 4-polytope|regular convex 4-polytope]] with [[W:Schläfli symbol|Schläfli symbol]] {3,3,4}. It has 8 vertices, 24 edges, 32 equilateral triangle faces, and 16 regular tetrahedron cells. It is the [[16-cell#Octahedral dipyramid|four-dimensional analogue of the octahedron]], and each of its four orthogonal central hyperplanes is an octahedron. The only planar regular polygons found in the 16-cell are face triangles and central plane squares, but the 16-cell also contains a skew regular octagon, its [[W:Petrie polygon|Petrie polygon]]. The chords of this regular octagon, which lies skew in 4-space, are those given above for the 16-cell, as opposed to those for the cube or the regular octagon in the plane. The 16-cell is a construct of 3 Petrie octagons which share the same 8 vertices but have disjoint sets of 8 edges each. The regular octad has higher symmetry in 4-space than it does in 2-space. The 16-cell is the 4-orthoplex, the simplest regular 4-polytope after the [[5-cell|4-simplex]]. All the larger regular 4-polytopes, including the 120-cell, are compounds of the 16-cell. The regular octagon exhibits this high symmetry only when embedded in 4-space at the vertices of the 16-cell. The 16-cell constitutes an [[W:Orthonormal basis|orthonormal basis]] for the choice of a 4-dimensional Cartesian reference frame, because its vertices define four orthogonal axes. The eight vertices of a unit-radius 16-cell are (±1, 0, 0, 0), (0, ±1, 0, 0), (0, 0, ±1, 0), (0, 0, 0, ±1). All vertices are connected by <small><math>\sqrt{2}</math></small> edges except opposite pairs. The vertex coordinates of the 16-cell form 6 central squares lying in 6 pairwise [[W:Orthogonal|orthogonal]] coordinate planes. Great squares in ''opposite'' planes that do not share an axis (e.g. in the ''xy'' and ''wz'' planes) are completely disjoint (they do not intersect at any vertices). These planes are [[W:Completely orthogonal|completely orthogonal]].{{Efn|name=Six orthogonal planes of the Cartesian basis}} Since this unit-radius coordinate system is convenient, let us derive the unit-radius 16-cell by skewing a unit-radius planar octagon, which has chords of length: :<math>r_1=\sqrt{2-\sqrt{2}} \approx 0.76537,r_2=\sqrt{2},r_3=\sqrt{2+\sqrt{2}} \approx 1.84776,r_4=2</math> We will need a planar octagon with rigid <math>r_2</math> chords, rather than one with rigid <math>r_1</math> edges. The octagon's <math>r_2</math> chords form two disjoint squares, which we can reposition in 3-space to form a cube by making them parallel, and in 4-space to form a 16-cell by making them completely orthogonal. The <math>r_2</math> chords form two disjoint great squares, visible in the orthogonal projection. These central squares are completely orthogonal: both parallel and perpendicular to each other. A ''simple'' rotation of the 16-cell in ''one'' of these two central planes rotates that square like a wheel, while the other square does not move. The four vertices of the rotating square orbit on a great circle. The <math>r_1</math> chords form a Petrie polygon which zig-zags back and forth between the two completely orthogonal <math>r_2</math> squares. The <math>r_3</math> chords form a circular helix, visible as a skew {8/3} polygram in the orthogonal projection. A ''double'' rotation of the 16-cell, in ''both'' of the two completely orthogonal <math>r_2</math> central square planes at once, moves the vertices along the circular helix over the <math>r_3</math> chords. [[W:Rotations in 4-dimensional Euclidean space|Rotations in 4-dimensional Euclidean space]] can be seen as the composition of two 2-dimensional rotations in completely orthogonal planes. The general rotation in 4-space is a double rotation in pairs of completely orthogonal planes. Two completely orthogonal planes are called invariant planes of the rotation when all points in the plane rotate on circles that remain in the plane, even as the whole plane tilts sideways (like a coin flipping) into another plane. The two completely orthogonal rotations of each plane (like a wheel, and like a coin flipping) are simultaneous but independent, in that they are not geometrically constrained to turn at the same rate. However, the most circular kind of rotation (as opposed to an elliptical double rotation of a rigid spherical object) occurs when the invariant planes do rotate through the same angle in the same time interval. Such equi-angled double rotations are called [[w:SO(4)#Isoclinic_rotations|isoclinic]], also [[w:William_Kingdon_Clifford|Clifford]] displacements. The 16-cell is the simplest possible frame in which to [[16-cell#Rotations|observe 4-dimensional rotations]] because its characteristic isoclinic rotations feature a single pair of invariant rotation planes. In the 16-cell an isoclinic rotation by 90° in any pair of invariant completely orthogonal square central planes takes every square central plane to its completely orthogonal square central plane in a twisting displacment, as they tilt sideways 90° into each other's plane while rotating 90° internally. All the vertices move at once on separate circular [[w:Geodesic|geodesics]], displaced 90° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. When the 90° isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 90°, but from the new orientation in a direction orthogonal to its first 90° displacement. After 360° of rotation each vertex reaches its antipodal position. The trajectory of each vertex over each 90° isoclinic rotational displacement is a one-eighth segment of its geodesic orbit. Its entire orbit traces a circular helix in 4-space, and also traces a great circle twice in one of the two moving invariant rotation planes. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once and returns to its original position, and the 16-cell returns to its original orientation. == Hypercubes == The long diameter of the unit-edge [[W:Hypercube|hypercube]] of dimension <small><math>n</math></small> is <small><math>\sqrt{n}</math></small>, so the unit-edge [[w:Tesseract|4-hypercube, the 16-point (8-cell) tesseract,]] has chords: :<math>r_1=\sqrt{1},r_2=\sqrt{2},r_3=\sqrt{3},r_4=\sqrt{4}</math> Uniquely in its 4-dimensional case, the hypercube's edge length equals its radius, like the hexagon. We call such polytopes ''radially equilateral'', because they can be constructed from equilateral triangles which meet at their center, each contributing two radii and an edge. The cuboctahedron and the 24-cell are also radially equilateral. The [[W:Tesseract|tesseract]] is the [[W:Regular convex 4-polytope|regular convex 4-polytope]] with [[W:Schläfli symbol|Schläfli symbol]] {4,3,3}. It has 16 vertices, 32 edges, 24 square faces, and 8 cube cells. It is the four-dimensional analogue of the cube. The tesseract is the [[W:Dual polytope|dual polytope]] of the 16-cell. They have the same Petrie polygon, the regular octagon, but the tesseract contains 2 disjoint instances and 4 distinct instances of the skew octagon. We can construct the tesseract by skewing two planar octagons. Because the tesseract is radially equilateral (unlike the 16-cell), we start with our original octagon of unit-edge length, rather than the octagon of edge length <small><math>\sqrt{2}</math></small> that we needed to build the unit-radius 16-cell. For our tesseract construction we skew each planar octagon into a cube, so we have a compound of two completely orthogonal cubes. Provided the planes were completely orthogonal in 4-space and we skewed them both the same way, the 16 vertices will be the vertices of a tesseract with half of its 32 edges missing. The 16-point tesseract is the convex hull of a compound of two 8-point 16-cells, in exact dimensional analogy to the way the 8-point cube is the convex hull of a [[W:Stellated octahedron|compound of two regular 4-point tetrahedra]]. The [[W:Demihypercube|demihypercubes]] occupy alternate vertices of the hypercubes. The diagonals of the square faces of the unit-radius tesseract are the <small><math>\sqrt{2}</math></small> edges of two unit-radius 16-cells, which are also the edges of the square central planes. Because the tesseract contains two 16-cells in alternate positions it has two sets of 6 orthogonal square central planes. Two angles are required to specify the relationship between two planes in 4-space. Pairs of planes within each 16-cell are 90° apart in one angle, and either 0° or 90° apart in the other angle. They are 90° apart in both angles if and only if they are completely orthogonal planes, 90° apart by isoclinic rotation, with no vertices in common and their corresponding vertices 180° apart. Otherwise they are 0° apart in one of the angles, 90° apart by simple rotation with their corresponding vertices 90° apart, and they intersect in one axis and lie in a common 3-dimensional hyperplane.{{Efn|A double rotation in which one of the two angles of rotation is 0°, so that one of the completely orthogonal invariant planes does not rotate, is called a simple rotation. Ordinary rotations observed in a 3-dimensional space are simple rotations.}} A pair of square central planes from alternate 16-cells are 60° apart by isoclinic rotation, with their corresponding vertices 120° apart. The planes are not orthogonal or parallel, so they intersect in a line somewhere, but they have no vertices in common, they have no 3-dimensional hyperplane in common, and they cannot reach each other by simple rotation. Such pairs of objects are called [[W:Clifford parallel|Clifford parallel]] because all their corresponding pairs of vertices are the same distance apart, although they are not parallel in the usual sense, because they have a common center. Not only the alternate 16-cells' corresponding square central planes, but also the 16-cells themselves, are Clifford parallel objects. We can rotate the tesseract isoclinically the way we rotated the 16-cell, by 90° in two completely orthogonal invariant square central planes, with the same effect on both alternate 16-cells. In the course of a 720° isoclinic rotation in invariant square central planes each vertex departs from all 8 vertex positions of its 16-cell just once and returns to its original position, but it does not visit the vertex positions of the other 16-cell. The skew octagon geodesic orbits of the 16 vertices are disjoint circular helixes, and those 16 circular helixes are Clifford parallel objects. == The 24-cell == In 2-space we have the radially equilateral 6-point hexagon. In 3-space we have the radially equilateral 12-point cuboctahedron, with 4 hexagonal central planes. In 4-space we have the radially equilateral 24-point 24-cell, with 4 cuboctahedral central hyperplanes and 16 hexagonal central planes. Great hexagons are a rounder choice than great squares for the invariant rotation planes in which to rotate a 4-polytope isoclinically. The complete hexagonal isoclinic revolution requires 720° like the square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 90° each. ... == The 600-cell == ... == Finally the 120-cell == ... == Conclusions == Fontaine and Hurley's discovery is more than a formula for the reciprocal of a regular ''n''-polygon diagonal. It also yields the discrete sequence of isocline chords of the distinct isoclinic rotation characteristic of a ''d''-dimensional regular polytope. The characteristic rotational chord sequence of the ''d''-polytope can be represented geometrically in two dimensions on a distinct star polygon, but it lies on a geodesic circle through ''d''-dimensional space. Fontaine and Hurley discovered the geodesic topology of polytopes generally. Their procedure will reveal the geodesics of arbitrary non-uniform polytopes, since it can be applied to a polytope of any dimensionality and irregularity, by first fitting the polytope to the smallest regular polygon whose chords include its chords. Fontaine and Hurley's discovery of a chordal formula for isoclinic rotations closes the circuit on Kappraff and Adamson's discovery of a rotational connection between dynamical systems, Steinbach's golden fields, and Coxeter's Euclidean geometry of ''n'' dimensions. Application of the Fontaine and Hurley procedure in higher-dimensional spaces demonstrates why the connection exists: because polytope sequences generally, from Steinbach's golden polygon chord sequences, to chord sequences in isoclinic rotation helixes, to subsumption relations in the sequence of regular 4-polytopes, arise as expressions of the reflections and rotations of distinct Coxeter symmetry groups, when those various groups interact. == Appendix: Sequence of regular 4-polytopes == {{Regular convex 4-polytopes|wiki=W:|columns=7}} == Notes == {{Notelist}} == Citations == {{Reflist}} == References == {{Refbegin}} * {{Cite journal | last=Steinbach | first=Peter | year=1997 | title=Golden fields: A case for the Heptagon | journal=Mathematics Magazine | volume=70 | issue=Feb 1997 | pages=22–31 | doi=10.1080/0025570X.1997.11996494 | jstor=2691048 | ref={{SfnRef|Steinbach|1997}} }} * {{Cite journal | last=Steinbach | first=Peter | year=2000 | title=Sections Beyond Golden| journal=Bridges: Mathematical Connections in Art, Music and Science | issue=2000 | pages=35-44 | url=https://archive.bridgesmathart.org/2000/bridges2000-35.pdf | ref={{SfnRef|Steinbach|2000}}}} * {{Cite journal | last1=Kappraff | first1=Jay | last2=Jablan | first2=Slavik | last3=Adamson | first3=Gary | last4=Sazdanovich | first4=Radmila | year=2004 | title=Golden Fields, Generalized Fibonacci Sequences, and Chaotic Matrices | journal=Forma | volume=19 | pages=367-387 | url=https://archive.bridgesmathart.org/2005/bridges2005-369.pdf | ref={{SfnRef|Kappraff, Jablan, Adamson & Sazdanovich|2004}} }} * {{Cite journal | last1=Kappraff | first1=Jay | last2=Adamson | first2=Gary | year=2004 | title=Polygons and Chaos | journal=Dynamical Systems and Geometric Theories | url=https://archive.bridgesmathart.org/2001/bridges2001-67.pdf | ref={{SfnRef|Kappraff & Adamson|2004}} }} * {{Cite journal | last1=Fontaine | first1=Anne | last2=Hurley | first2=Susan | year=2006 | title=Proof by Picture: Products and Reciprocals of Diagonal Length Ratios in the Regular Polygon | journal=Forum Geometricorum | volume=6 | pages=97-101 | url=https://scispace.com/pdf/proof-by-picture-products-and-reciprocals-of-diagonal-length-1aian8mgp9.pdf }} {{Refend}} nxvhffpkwt0cu8xvnsfo6dv7pmxagkq 2809767 2809763 2026-05-16T22:16:29Z Dc.samizdat 2856930 /* The 8-point regular polytopes */ 2809767 wikitext text/x-wiki {{align|center|David Brooks Christie}} {{align|center|dc@samizdat.org}} {{align|center|Draft in progress}} {{align|center|January 2026 - April 2026}} <blockquote>Steinbach discovered the formula for the ratios of diagonal to side in the regular polygons. Fontaine and Hurley extended this result, discovering a formula for the reciprocal of a regular polygon chord derived geometrically from the chord's star polygon. We observe that these findings in plane geometry apply more generally, to polytopes of any dimensionality. Fontaine and Hurley's geometric procedure for finding the reciprocals of the chords of a regular polygon from their star polygons also finds the rotational geodesics of any polytope of any dimensionality.</blockquote> == Introduction == Steinbach discovered the Diagonal Product Formula and the Golden Fields family of ratios of diagonal to side in the regular polygons. He showed how this family extends beyond the pentagon {5} with its well-known golden bisection proportional to 𝜙, finding that the heptagon {7} has an analogous trisection, the nonagon {9} has an analogous quadrasection, and the hendecagon {11} has an analogous pentasection, an extended family of golden proportions with quasiperiodic properties. Kappraff and Adamson extended these findings in plane geometry to a theory of Generalized Fibonacci Sequences, showing that the Golden Fields not only do not end with the hendecagon, they form an infinite number of periodic trajectories when operated on by the Mandelbrot operator. They found a relation between the edges of star polygons and dynamical systems in the state of chaos, revealing a connection between chaos theory, number, and rotations in Coxeter Euclidean geometry. Fontaine and Hurley examined Steinbach's finding that the length of each chord of a regular polygon is both the product of two chords and the sum of a set of smaller chords, so that in rotations to add is to multiply. They illustrated Steinbach's sets of additive chords lying parallel to each other in the plane (pointing in the same direction), and by applying Steinbach's formula more generally they found another summation relation of signed parallel chords (pointing in opposite directions) which relates each chord length to its reciprocal, and relates the summation to a distinct star polygon rotation. We examine these remarkable findings (which stem from study of the chords of humble regular polygons) in higher-dimensional spaces, specifically in the chords, polygons and rotations of the [[120-cell]], the largest four-dimensional regular convex polytope. == Visualizing the 120-cell == {| class="wikitable floatright" width="400" |style="vertical-align:top"|[[File:120-cell.gif|200px]]<br>Orthographic projection of the 600-point 120-cell <small><math>\{5,3,3\}</math></small> performing a [[W:SO(4)#Geometry of 4D rotations|simple rotation]].{{Sfn|Hise|2011|loc=File:120-cell.gif|ps=; "Created by Jason Hise with Maya and Macromedia Fireworks.

Therefore even though it is translucent, only its outer surface is visible. The complex interior parts of the 120-cell, all its inscribed 5-cells, 16-cells, 8-cells, 24-cells, 600-cells and its much larger inventory of polyhedra, are completely invisible in this view, as none of their edges are rendered at all. |style="vertical-align:top"|[[File:Ortho solid 016-uniform polychoron p33-t0.png|200px]]<br>Orthographic projection of the 600-point [[W:Great grand stellated 120-cell|great grand stellated 120-cell]] <small><math>\{\tfrac{5}{2},3,3\}</math></small>.{{Sfn|Ruen: Great grand stellated 120-cell|2007}} The 120-cell is its convex hull. The projection to the left renders only the 120-cell's shortest chord, its 1200 edges. The projection above also renders only one of the 120-cell's 30 chords, the edges of its 120 inscribed regular 5-cells.

The 120-cell is the convex hull of a regular [[120-cell#Relationships among interior polytopes|compound of each of the 6 regular convex 4-polytopes]]. They are the [[5-cell|5-point (5-cell) 4-simplex]], the [[16-cell|8-point (16-cell) 4-orthoplex]], the [[W:Tesseract|16-point (8-cell) tesseract]], the [[24-cell|24-point (24-cell)]], the [[600-cell|120-point (600-cell)]], and the [[120-cell|600-point (120-cell)]]. The 120-cell is the convex hull of a compound of 120 disjoint regular 5-cells, of 75 disjoint 16-cells, of 25 disjoint 24-cells, and of 5 disjoint 600-cells. The 120-cell contains an even larger inventory of irregular polytopes, created by the intersection of multiple instances of these component regular 4-polytopes. Many are quite unexpected, because they do not occur as components of any regular polytope smaller than the 120-cell. As just one example among the [[120-cell#Concentric hulls|sections of the 120-cell]], there is an irregular 24-point polyhedron with 16 triangle faces and 4 nonagon {9} faces.{{Sfn|Moxness|}} Most renderings of the 120-cell, like the rotating projection here, only illustrate its outer surface, which is a honeycomb of face-bonded dodecahedral cells. Only the objects in its 3-dimensional surface are rendered, namely the 120 dodecahedra, their pentagon faces, and their edges. Although the 120-cell has chords of 30 distinct lengths, in this kind of simplified rendering only the 120-cell's own edges (its shortest chord) are shown. Its 29 interior chords, the edges of objects in the interior of the 120-cell, are not rendered, so interior objects are not visible at all. Visualizing the complete interior of the 600-vertex 120-cell in a single image is impractical because of its complexity. Only four 120-cell edges are incident at each vertex, but [[120-cell#Chords|600 chords (of all 30 lengths)]] are incident at ''each'' vertex. == Compounds in the 120-cell == The 8-point (16-cell), not the 5-point (5-cell), is the smallest building block; it compounds to every larger regular 4-polytope. The 5-point (5-cell) does compound to the 600-point (120-cell), but it does not fit into any smaller regular 4-polytope. The 8-point (16-cell) compounds by 2 in the 16-point (8-cell), and by 3 in the 24-point (24-cell). The 16-point (8-cell) compounds in the 24-point (24-cell) by 3 non-disjoint instances of itself, with each of the 24 vertices shared by two 16-point (8-cells). The 24-point (24-cell) compounds by 5 disjoint instances of itself in the 120-point (600-cell), and the 120-point (600-cell) compounds by 5 disjoint instances of itself in the 600-point (120-cell). The 24-point (24-cell) also compounds by <math>5^2</math> non-disjoint instances of itself in the 120-point (600-cell); it compounds in 5 disjoint instances of itself, 10 (not 5) different ways. Whichever set of 5 disjoint 24-point (24-cells) are assembled, the resulting 120-point (600-cell) contains 25 distinct 24-point (24-cells), not just 5 (or 10). This implies that 15 disjoint 8-point (16-cells) will construct a 120-point (600-cell), which will contain 75 distinct 8-point (16-cells). The 600-point (120-cell) is 5 disjoint 120-point (600-cells), just 2 different ways (not 5 or 10 ways), so it is 10 distinct 120-point (600-cells). This implies that the 8-point (16-cell) compounds by 3 times <math>5^2</math> (75) disjoint instances of itself in the 600-point (120-cell), which contains <math>3^2</math> times <math>5^2</math> (225) distinct instances of the 24-point (24-cell), and <math>3^3</math> times <math>5^2</math> (675) distinct instances of the 8-point (16-cell). These facts were discovered painstakingly by various researchers, and no one has found a general rule governing subsumption relations among regular polytopes. The reasons for some of their numeric incidence relations are far from obvious. [[W:Pieter Hendrik Schoute|Schoute]] was the first to see that the 120-point (600-cell) is a compound of 5 24-point (24-cells) ''10 different ways'', and after he saw it a hundred years lapsed until Denney, Hooker, Johnson, Robinson, Butler & Claiborne proved his result, and showed why.{{Sfn|Denney, Hooker, Johnson, Robinson, Butler & Claiborne|2020|loc=''The geometry of H4 polytopes''}} So much for the compounds of 16-cells. The 120-cell is also the convex hull of the compound of 120 disjoint regular 5-cells. That stellated compound (without its convex hull of 120-cell edges) is the [[w:Great_grand_stellated_120-cell|great grand stellated 120-cell]] illustrated above, the final regular [[W:Stellation|stellation]] of the 120-cell, and the only [[W:Schläfli-Hess polychoron|regular star 4-polytope]] to have the 120-cell for its convex hull. The edges of the great grand stellated 120-cell are <math>\phi^6</math> as long as those of its 120-cell [[W:List of polyhedral stellations#Stellation process|stellation core]] deep inside. The compound of 120 disjoint 5-point (5-cells) can be seen to be equivalent to the compound of 5 disjoint 120-point (600-cells), as follows. Beginning with a single 120-point (600-cell), expand each vertex into a regular 5-cell, by adding 4 new equidistant vertices, such that the 5 vertices form a regular 5-cell inscribed in the 3-sphere. The 120 5-cells are disjoint, and the 600 vertices form 5 disjoint 120-point (600-cells): a 120-cell. == Thirty distinguished distances == The 30 numbers listed in the table are all-important in Euclidean geometry. A case can be made on symmetry grounds that their squares are the 30 most important numbers between 0 and 4. The 30 rows of the table are the 30 distinct [[120-cell#Geodesic rectangles|chord lengths of the unit-radius 120-cell]], the largest regular convex 4-polytope. Since the 120-cell subsumes all smaller regular polytopes, its 30 chords are the complete chord set of all the regular polytopes that can be constructed in the first four dimensions of Euclidean space, except for regular polygons of more than 15 sides. {| class="wikitable" style="white-space:nowrap;text-align:center" !rowspan=2|<math>c_t</math> !rowspan=2|arc

regular polytopes == In 2-space we have the regular 8-point octagon, in 3-space the regular 8-point cube, and in 4-space the regular 8-point [[16-cell]]. A planar octagon with rigid edges of unit length has chords of length: :<math>r_1=1,r_2=\sqrt{2+\sqrt{2}} \approx 1.84776,r_3=1+\sqrt{2} \approx 2.41421,r_4=\sqrt{4 + \sqrt{8}} \approx 2.61313</math> The chord ratio <math>r_3=1+\sqrt{2}</math> is a geometrical proportion, the [[W:Silver ratio|silver ratio]]. Fontaine and Hurley's procedure for obtaining the reciprocal of a chord tells us that: :<math>r_3-r_1-r_1=1/r_3 \approx 0.41421</math> Note that <math>1/r_3=\sqrt{2}-1=r_3-2</math>. If we embed this planar octagon in 3-space, we can make it skew, repositioning its vertices so that each is one unit-edge length distant from three others instead of two others, at the vertices of a unit-edge cube with chords of length: :<math>r_1=1, r_2=\sqrt{2}, r_3=\sqrt{3}, r_4=\sqrt{2}</math> If we embed this cube in 4-space, we can skew it some more, repositioning its vertices so that each is one unit-edge length distant from six others instead of three others, at the vertices of a unit-edge 4-polytope with chords of length: :<math>r_1=1,r_2=1,r_3=1,r_4=\sqrt{2}</math> All of its chords except its long diameters are the same unit length as its edge. In fact they are its 24 edges, and it is a 16-cell of radius <small><math>1/\sqrt{2}</math></small>. [[File:octagon16cell.png|thumb|Orthogonal projection of a regular 16-cell to the [[16-cell#Projections|B<sub>4</sub> Coxeter plane]]. Only its edges are shown; its long diameter chords are not drawn. All 24 edges are the same length. Only the edges of the two disjoint squares lie parallel to the projection plane, in completely orthogonal central planes.]] The [[16-cell]] is the [[W:Regular convex 4-polytope|regular convex 4-polytope]] with [[W:Schläfli symbol|Schläfli symbol]] {3,3,4}. It has 8 vertices, 24 edges, 32 equilateral triangle faces, and 16 regular tetrahedron cells. It is the [[16-cell#Octahedral dipyramid|four-dimensional analogue of the octahedron]], and each of its four orthogonal central hyperplanes is an octahedron. The only planar regular polygons found in the 16-cell are face triangles and central plane squares, but the 16-cell also contains a skew regular octagon, its [[W:Petrie polygon|Petrie polygon]]. The chords of this regular octagon, which lies skew in 4-space, are those given above for the 16-cell, as opposed to those for the cube or the regular octagon in the plane. The 16-cell is a construct of 3 Petrie octagons which share the same 8 vertices but have disjoint sets of 8 edges each. The regular octad has higher symmetry in 4-space than it does in 2-space. The 16-cell is the 4-orthoplex, the simplest regular 4-polytope after the [[5-cell|4-simplex]]. All the larger regular 4-polytopes, including the 120-cell, are compounds of the 16-cell. The regular octagon exhibits this high symmetry only when embedded in 4-space at the vertices of the 16-cell. The 16-cell constitutes an [[W:Orthonormal basis|orthonormal basis]] for the choice of a 4-dimensional Cartesian reference frame, because its vertices define four orthogonal axes. The eight vertices of a unit-radius 16-cell are (±1, 0, 0, 0), (0, ±1, 0, 0), (0, 0, ±1, 0), (0, 0, 0, ±1). All vertices are connected by <small><math>\sqrt{2}</math></small> edges except opposite pairs. The vertex coordinates of the 16-cell form 6 central squares lying in 6 pairwise [[W:Orthogonal|orthogonal]] coordinate planes. Great squares in ''opposite'' planes that do not share an axis (e.g. in the ''xy'' and ''wz'' planes) are completely disjoint (they do not intersect at any vertices). These planes are [[W:Completely orthogonal|completely orthogonal]].{{Efn|name=Six orthogonal planes of the Cartesian basis}} Since this unit-radius coordinate system is convenient, let us derive the unit-radius 16-cell by skewing a unit-radius planar octagon, which has chords of length: :<math>r_1=\sqrt{2-\sqrt{2}} \approx 0.76537,r_2=\sqrt{2},r_3=\sqrt{2+\sqrt{2}} \approx 1.84776,r_4=2</math> We will need a planar octagon with rigid <math>r_2</math> chords, rather than one with rigid <math>r_1</math> edges. The octagon's <math>r_2</math> chords form two disjoint squares, which we can reposition in 3-space to form a cube by making them parallel, and in 4-space to form a 16-cell by making them completely orthogonal. The <math>r_2</math> chords form two disjoint great squares, visible in the orthogonal projection. These central squares are completely orthogonal: both parallel and perpendicular to each other. A ''simple'' rotation of the 16-cell in ''one'' of these two central planes rotates that square like a wheel, while the other square does not move. The four vertices of the rotating square orbit on a great circle. The <math>r_1</math> chords form a Petrie polygon which zig-zags back and forth between the two completely orthogonal <math>r_2</math> squares. The <math>r_3</math> chords form a circular helix, visible as a skew {8/3} polygram in the orthogonal projection. A ''double'' rotation of the 16-cell, in ''both'' of the two completely orthogonal <math>r_2</math> central square planes at once, moves the vertices along the circular helix over the <math>r_3</math> chords. [[W:Rotations in 4-dimensional Euclidean space|Rotations in 4-dimensional Euclidean space]] can be seen as the composition of two 2-dimensional rotations in completely orthogonal planes. The general rotation in 4-space is a double rotation in pairs of completely orthogonal planes. Two completely orthogonal planes are called invariant planes of the rotation when all points in the plane rotate on circles that remain in the plane, even as the whole plane tilts sideways (like a coin flipping) into another plane. The two completely orthogonal rotations of each plane (like a wheel, and like a coin flipping) are simultaneous but independent, in that they are not geometrically constrained to turn at the same rate. However, the most circular kind of rotation (as opposed to an elliptical double rotation of a rigid spherical object) occurs when the invariant planes do rotate through the same angle in the same time interval. Such equi-angled double rotations are called [[w:SO(4)#Isoclinic_rotations|isoclinic]], also [[w:William_Kingdon_Clifford|Clifford]] displacements. The 16-cell is the simplest possible frame in which to [[16-cell#Rotations|observe 4-dimensional rotations]] because its characteristic isoclinic rotations feature a single pair of invariant rotation planes. In the 16-cell an isoclinic rotation by 90° in any pair of invariant completely orthogonal square central planes takes every square central plane to its completely orthogonal square central plane in a twisting displacment, as they tilt sideways 90° into each other's plane while rotating 90° internally. All the vertices move at once on separate circular [[w:Geodesic|geodesics]], displaced 90° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. When the 90° isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 90°, but from the new orientation in a direction orthogonal to its first 90° displacement. After 360° of rotation each vertex reaches its antipodal position. The trajectory of each vertex over each 90° isoclinic rotational displacement is a one-eighth segment of its geodesic orbit. Its entire orbit traces a circular helix in 4-space over eight <math>r_3</math> chords, and also traces a great circle twice over four <math>r_2</math> chords in one of the two moving invariant rotation planes. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once and returns to its original position, and the 16-cell returns to its original orientation. == Hypercubes == The long diameter of the unit-edge [[W:Hypercube|hypercube]] of dimension <small><math>n</math></small> is <small><math>\sqrt{n}</math></small>, so the unit-edge [[w:Tesseract|4-hypercube, the 16-point (8-cell) tesseract,]] has chords: :<math>r_1=\sqrt{1},r_2=\sqrt{2},r_3=\sqrt{3},r_4=\sqrt{4}</math> Uniquely in its 4-dimensional case, the hypercube's edge length equals its radius, like the hexagon. We call such polytopes ''radially equilateral'', because they can be constructed from equilateral triangles which meet at their center, each contributing two radii and an edge. The cuboctahedron and the 24-cell are also radially equilateral. The [[W:Tesseract|tesseract]] is the [[W:Regular convex 4-polytope|regular convex 4-polytope]] with [[W:Schläfli symbol|Schläfli symbol]] {4,3,3}. It has 16 vertices, 32 edges, 24 square faces, and 8 cube cells. It is the four-dimensional analogue of the cube. The tesseract is the [[W:Dual polytope|dual polytope]] of the 16-cell. They have the same Petrie polygon, the regular octagon, but the tesseract contains 2 disjoint instances and 4 distinct instances of the skew octagon. We can construct the tesseract by skewing two planar octagons. Because the tesseract is radially equilateral (unlike the 16-cell), we start with our original octagon of unit-edge length, rather than the octagon of edge length <small><math>\sqrt{2}</math></small> that we needed to build the unit-radius 16-cell. For our tesseract construction we skew each planar octagon into a cube, so we have a compound of two completely orthogonal cubes. Provided the planes were completely orthogonal in 4-space and we skewed them both the same way, the 16 vertices will be the vertices of a tesseract with half of its 32 edges missing. The 16-point tesseract is the convex hull of a compound of two 8-point 16-cells, in exact dimensional analogy to the way the 8-point cube is the convex hull of a [[W:Stellated octahedron|compound of two regular 4-point tetrahedra]]. The [[W:Demihypercube|demihypercubes]] occupy alternate vertices of the hypercubes. The diagonals of the square faces of the unit-radius tesseract are the <small><math>\sqrt{2}</math></small> edges of two unit-radius 16-cells, which are also the edges of the square central planes. Because the tesseract contains two 16-cells in alternate positions it has two sets of 6 orthogonal square central planes. Two angles are required to specify the relationship between two planes in 4-space. Pairs of planes within each 16-cell are 90° apart in one angle, and either 0° or 90° apart in the other angle. They are 90° apart in both angles if and only if they are completely orthogonal planes, 90° apart by isoclinic rotation, with no vertices in common and their corresponding vertices 180° apart. Otherwise they are 0° apart in one of the angles, 90° apart by simple rotation with their corresponding vertices 90° apart, and they intersect in one axis and lie in a common 3-dimensional hyperplane.{{Efn|A double rotation in which one of the two angles of rotation is 0°, so that one of the completely orthogonal invariant planes does not rotate, is called a simple rotation. Ordinary rotations observed in a 3-dimensional space are simple rotations.}} A pair of square central planes from alternate 16-cells are 60° apart by isoclinic rotation, with their corresponding vertices 120° apart. The planes are not orthogonal or parallel, so they intersect in a line somewhere, but they have no vertices in common, they have no 3-dimensional hyperplane in common, and they cannot reach each other by simple rotation. Such pairs of objects are called [[W:Clifford parallel|Clifford parallel]] because all their corresponding pairs of vertices are the same distance apart, although they are not parallel in the usual sense, because they have a common center. Not only the alternate 16-cells' corresponding square central planes, but also the 16-cells themselves, are Clifford parallel objects. We can rotate the tesseract isoclinically the way we rotated the 16-cell, by 90° in two completely orthogonal invariant square central planes, with the same effect on both alternate 16-cells. In the course of a 720° isoclinic rotation in invariant square central planes each vertex departs from all 8 vertex positions of its 16-cell just once and returns to its original position, but it does not visit the vertex positions of the other 16-cell. The skew octagon geodesic orbits of the 16 vertices are disjoint circular helixes, and those 16 circular helixes are Clifford parallel objects. == The 24-cell == In 2-space we have the radially equilateral 6-point hexagon. In 3-space we have the radially equilateral 12-point cuboctahedron, with 4 hexagonal central planes. In 4-space we have the radially equilateral 24-point 24-cell, with 4 cuboctahedral central hyperplanes and 16 hexagonal central planes. Great hexagons are a rounder choice than great squares for the invariant rotation planes in which to rotate a 4-polytope isoclinically. The complete hexagonal isoclinic revolution requires 720° like the square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 90° each. ... == The 600-cell == ... == Finally the 120-cell == ... == Conclusions == Fontaine and Hurley's discovery is more than a formula for the reciprocal of a regular ''n''-polygon diagonal. It also yields the discrete sequence of isocline chords of the distinct isoclinic rotation characteristic of a ''d''-dimensional regular polytope. The characteristic rotational chord sequence of the ''d''-polytope can be represented geometrically in two dimensions on a distinct star polygon, but it lies on a geodesic circle through ''d''-dimensional space. Fontaine and Hurley discovered the geodesic topology of polytopes generally. Their procedure will reveal the geodesics of arbitrary non-uniform polytopes, since it can be applied to a polytope of any dimensionality and irregularity, by first fitting the polytope to the smallest regular polygon whose chords include its chords. Fontaine and Hurley's discovery of a chordal formula for isoclinic rotations closes the circuit on Kappraff and Adamson's discovery of a rotational connection between dynamical systems, Steinbach's golden fields, and Coxeter's Euclidean geometry of ''n'' dimensions. Application of the Fontaine and Hurley procedure in higher-dimensional spaces demonstrates why the connection exists: because polytope sequences generally, from Steinbach's golden polygon chord sequences, to chord sequences in isoclinic rotation helixes, to subsumption relations in the sequence of regular 4-polytopes, arise as expressions of the reflections and rotations of distinct Coxeter symmetry groups, when those various groups interact. == Appendix: Sequence of regular 4-polytopes == {{Regular convex 4-polytopes|wiki=W:|columns=7}} == Notes == {{Notelist}} == Citations == {{Reflist}} == References == {{Refbegin}} * {{Cite journal | last=Steinbach | first=Peter | year=1997 | title=Golden fields: A case for the Heptagon | journal=Mathematics Magazine | volume=70 | issue=Feb 1997 | pages=22–31 | doi=10.1080/0025570X.1997.11996494 | jstor=2691048 | ref={{SfnRef|Steinbach|1997}} }} * {{Cite journal | last=Steinbach | first=Peter | year=2000 | title=Sections Beyond Golden| journal=Bridges: Mathematical Connections in Art, Music and Science | issue=2000 | pages=35-44 | url=https://archive.bridgesmathart.org/2000/bridges2000-35.pdf | ref={{SfnRef|Steinbach|2000}}}} * {{Cite journal | last1=Kappraff | first1=Jay | last2=Jablan | first2=Slavik | last3=Adamson | first3=Gary | last4=Sazdanovich | first4=Radmila | year=2004 | title=Golden Fields, Generalized Fibonacci Sequences, and Chaotic Matrices | journal=Forma | volume=19 | pages=367-387 | url=https://archive.bridgesmathart.org/2005/bridges2005-369.pdf | ref={{SfnRef|Kappraff, Jablan, Adamson & Sazdanovich|2004}} }} * {{Cite journal | last1=Kappraff | first1=Jay | last2=Adamson | first2=Gary | year=2004 | title=Polygons and Chaos | journal=Dynamical Systems and Geometric Theories | url=https://archive.bridgesmathart.org/2001/bridges2001-67.pdf | ref={{SfnRef|Kappraff & Adamson|2004}} }} * {{Cite journal | last1=Fontaine | first1=Anne | last2=Hurley | first2=Susan | year=2006 | title=Proof by Picture: Products and Reciprocals of Diagonal Length Ratios in the Regular Polygon | journal=Forum Geometricorum | volume=6 | pages=97-101 | url=https://scispace.com/pdf/proof-by-picture-products-and-reciprocals-of-diagonal-length-1aian8mgp9.pdf }} {{Refend}} h4od4l6j2xumnlrcey5cmu4gm8hghbe 2809770 2809767 2026-05-16T22:19:34Z Dc.samizdat 2856930 /* The 8-point regular polytopes */ 2809770 wikitext text/x-wiki {{align|center|David Brooks Christie}} {{align|center|dc@samizdat.org}} {{align|center|Draft in progress}} {{align|center|January 2026 - April 2026}} <blockquote>Steinbach discovered the formula for the ratios of diagonal to side in the regular polygons. Fontaine and Hurley extended this result, discovering a formula for the reciprocal of a regular polygon chord derived geometrically from the chord's star polygon. We observe that these findings in plane geometry apply more generally, to polytopes of any dimensionality. Fontaine and Hurley's geometric procedure for finding the reciprocals of the chords of a regular polygon from their star polygons also finds the rotational geodesics of any polytope of any dimensionality.</blockquote> == Introduction == Steinbach discovered the Diagonal Product Formula and the Golden Fields family of ratios of diagonal to side in the regular polygons. He showed how this family extends beyond the pentagon {5} with its well-known golden bisection proportional to 𝜙, finding that the heptagon {7} has an analogous trisection, the nonagon {9} has an analogous quadrasection, and the hendecagon {11} has an analogous pentasection, an extended family of golden proportions with quasiperiodic properties. Kappraff and Adamson extended these findings in plane geometry to a theory of Generalized Fibonacci Sequences, showing that the Golden Fields not only do not end with the hendecagon, they form an infinite number of periodic trajectories when operated on by the Mandelbrot operator. They found a relation between the edges of star polygons and dynamical systems in the state of chaos, revealing a connection between chaos theory, number, and rotations in Coxeter Euclidean geometry. Fontaine and Hurley examined Steinbach's finding that the length of each chord of a regular polygon is both the product of two chords and the sum of a set of smaller chords, so that in rotations to add is to multiply. They illustrated Steinbach's sets of additive chords lying parallel to each other in the plane (pointing in the same direction), and by applying Steinbach's formula more generally they found another summation relation of signed parallel chords (pointing in opposite directions) which relates each chord length to its reciprocal, and relates the summation to a distinct star polygon rotation. We examine these remarkable findings (which stem from study of the chords of humble regular polygons) in higher-dimensional spaces, specifically in the chords, polygons and rotations of the [[120-cell]], the largest four-dimensional regular convex polytope. == Visualizing the 120-cell == {| class="wikitable floatright" width="400" |style="vertical-align:top"|[[File:120-cell.gif|200px]]<br>Orthographic projection of the 600-point 120-cell <small><math>\{5,3,3\}</math></small> performing a [[W:SO(4)#Geometry of 4D rotations|simple rotation]].{{Sfn|Hise|2011|loc=File:120-cell.gif|ps=; "Created by Jason Hise with Maya and Macromedia Fireworks.

Therefore even though it is translucent, only its outer surface is visible. The complex interior parts of the 120-cell, all its inscribed 5-cells, 16-cells, 8-cells, 24-cells, 600-cells and its much larger inventory of polyhedra, are completely invisible in this view, as none of their edges are rendered at all. |style="vertical-align:top"|[[File:Ortho solid 016-uniform polychoron p33-t0.png|200px]]<br>Orthographic projection of the 600-point [[W:Great grand stellated 120-cell|great grand stellated 120-cell]] <small><math>\{\tfrac{5}{2},3,3\}</math></small>.{{Sfn|Ruen: Great grand stellated 120-cell|2007}} The 120-cell is its convex hull.

The 120-cell is the convex hull of a regular [[120-cell#Relationships among interior polytopes|compound of each of the 6 regular convex 4-polytopes]]. They are the [[5-cell|5-point (5-cell) 4-simplex]], the [[16-cell|8-point (16-cell) 4-orthoplex]], the [[W:Tesseract|16-point (8-cell) tesseract]], the [[24-cell|24-point (24-cell)]], the [[600-cell|120-point (600-cell)]], and the [[120-cell|600-point (120-cell)]]. The 120-cell is the convex hull of a compound of 120 disjoint regular 5-cells, of 75 disjoint 16-cells, of 25 disjoint 24-cells, and of 5 disjoint 600-cells. The 120-cell contains an even larger inventory of irregular polytopes, created by the intersection of multiple instances of these component regular 4-polytopes. Many are quite unexpected, because they do not occur as components of any regular polytope smaller than the 120-cell. As just one example among the [[120-cell#Concentric hulls|sections of the 120-cell]], there is an irregular 24-point polyhedron with 16 triangle faces and 4 nonagon {9} faces.{{Sfn|Moxness|}} Most renderings of the 120-cell, like the rotating projection here, only illustrate its outer surface, which is a honeycomb of face-bonded dodecahedral cells. Only the objects in its 3-dimensional surface are rendered, namely the 120 dodecahedra, their pentagon faces, and their edges. Although the 120-cell has chords of 30 distinct lengths, in this kind of simplified rendering only the 120-cell's own edges (its shortest chord) are shown. Its 29 interior chords, the edges of objects in the interior of the 120-cell, are not rendered, so interior objects are not visible at all. Visualizing the complete interior of the 600-vertex 120-cell in a single image is impractical because of its complexity. Only four 120-cell edges are incident at each vertex, but [[120-cell#Chords|600 chords (of all 30 lengths)]] are incident at ''each'' vertex. == Compounds in the 120-cell == The 8-point (16-cell), not the 5-point (5-cell), is the smallest building block; it compounds to every larger regular 4-polytope. The 5-point (5-cell) does compound to the 600-point (120-cell), but it does not fit into any smaller regular 4-polytope. The 8-point (16-cell) compounds by 2 in the 16-point (8-cell), and by 3 in the 24-point (24-cell). The 16-point (8-cell) compounds in the 24-point (24-cell) by 3 non-disjoint instances of itself, with each of the 24 vertices shared by two 16-point (8-cells). The 24-point (24-cell) compounds by 5 disjoint instances of itself in the 120-point (600-cell), and the 120-point (600-cell) compounds by 5 disjoint instances of itself in the 600-point (120-cell). The 24-point (24-cell) also compounds by <math>5^2</math> non-disjoint instances of itself in the 120-point (600-cell); it compounds in 5 disjoint instances of itself, 10 (not 5) different ways. Whichever set of 5 disjoint 24-point (24-cells) are assembled, the resulting 120-point (600-cell) contains 25 distinct 24-point (24-cells), not just 5 (or 10). This implies that 15 disjoint 8-point (16-cells) will construct a 120-point (600-cell), which will contain 75 distinct 8-point (16-cells). The 600-point (120-cell) is 5 disjoint 120-point (600-cells), just 2 different ways (not 5 or 10 ways), so it is 10 distinct 120-point (600-cells). This implies that the 8-point (16-cell) compounds by 3 times <math>5^2</math> (75) disjoint instances of itself in the 600-point (120-cell), which contains <math>3^2</math> times <math>5^2</math> (225) distinct instances of the 24-point (24-cell), and <math>3^3</math> times <math>5^2</math> (675) distinct instances of the 8-point (16-cell). These facts were discovered painstakingly by various researchers, and no one has found a general rule governing subsumption relations among regular polytopes. The reasons for some of their numeric incidence relations are far from obvious. [[W:Pieter Hendrik Schoute|Schoute]] was the first to see that the 120-point (600-cell) is a compound of 5 24-point (24-cells) ''10 different ways'', and after he saw it a hundred years lapsed until Denney, Hooker, Johnson, Robinson, Butler & Claiborne proved his result, and showed why.{{Sfn|Denney, Hooker, Johnson, Robinson, Butler & Claiborne|2020|loc=''The geometry of H4 polytopes''}} So much for the compounds of 16-cells. The 120-cell is also the convex hull of the compound of 120 disjoint regular 5-cells. That stellated compound (without its convex hull of 120-cell edges) is the [[w:Great_grand_stellated_120-cell|great grand stellated 120-cell]] illustrated above, the final regular [[W:Stellation|stellation]] of the 120-cell, and the only [[W:Schläfli-Hess polychoron|regular star 4-polytope]] to have the 120-cell for its convex hull. The edges of the great grand stellated 120-cell are <math>\phi^6</math> as long as those of its 120-cell [[W:List of polyhedral stellations#Stellation process|stellation core]] deep inside. The compound of 120 disjoint 5-point (5-cells) can be seen to be equivalent to the compound of 5 disjoint 120-point (600-cells), as follows. Beginning with a single 120-point (600-cell), expand each vertex into a regular 5-cell, by adding 4 new equidistant vertices, such that the 5 vertices form a regular 5-cell inscribed in the 3-sphere. The 120 5-cells are disjoint, and the 600 vertices form 5 disjoint 120-point (600-cells): a 120-cell. == Thirty distinguished distances == The 30 numbers listed in the table are all-important in Euclidean geometry. A case can be made on symmetry grounds that their squares are the 30 most important numbers between 0 and 4. The 30 rows of the table are the 30 distinct [[120-cell#Geodesic rectangles|chord lengths of the unit-radius 120-cell]], the largest regular convex 4-polytope. Since the 120-cell subsumes all smaller regular polytopes, its 30 chords are the complete chord set of all the regular polytopes that can be constructed in the first four dimensions of Euclidean space, except for regular polygons of more than 15 sides. {| class="wikitable" style="white-space:nowrap;text-align:center" !rowspan=2|<math>c_t</math> !rowspan=2|arc

regular polytopes == In 2-space we have the regular 8-point octagon, in 3-space the regular 8-point cube, and in 4-space the regular 8-point [[16-cell]]. A planar octagon with rigid edges of unit length has chords of length: :<math>r_1=1,r_2=\sqrt{2+\sqrt{2}} \approx 1.84776,r_3=1+\sqrt{2} \approx 2.41421,r_4=\sqrt{4 + \sqrt{8}} \approx 2.61313</math> The chord ratio <math>r_3=1+\sqrt{2}</math> is a geometrical proportion, the [[W:Silver ratio|silver ratio]]. Fontaine and Hurley's procedure for obtaining the reciprocal of a chord tells us that: :<math>r_3-r_1-r_1=1/r_3 \approx 0.41421</math> Note that <math>1/r_3=\sqrt{2}-1=r_3-2</math>. If we embed this planar octagon in 3-space, we can make it skew, repositioning its vertices so that each is one unit-edge length distant from three others instead of two others, at the vertices of a unit-edge cube with chords of length: :<math>r_1=1, r_2=\sqrt{2}, r_3=\sqrt{3}, r_4=\sqrt{2}</math> If we embed this cube in 4-space, we can skew it some more, repositioning its vertices so that each is one unit-edge length distant from six others instead of three others, at the vertices of a unit-edge 4-polytope with chords of length: :<math>r_1=1,r_2=1,r_3=1,r_4=\sqrt{2}</math> All of its chords except its long diameters are the same unit length as its edge. In fact they are its 24 edges, and it is a 16-cell of radius <small><math>1/\sqrt{2}</math></small>. [[File:octagon16cell.png|thumb|Orthogonal projection of a regular 16-cell to the [[16-cell#Projections|B<sub>4</sub> Coxeter plane]]. Only its edges are shown; its long diameter chords are not drawn. All 24 edges are the same length. Only the edges of the two disjoint squares lie parallel to the projection plane, in completely orthogonal central planes.]] The [[16-cell]] is the [[W:Regular convex 4-polytope|regular convex 4-polytope]] with [[W:Schläfli symbol|Schläfli symbol]] {3,3,4}. It has 8 vertices, 24 edges, 32 equilateral triangle faces, and 16 regular tetrahedron cells. It is the [[16-cell#Octahedral dipyramid|four-dimensional analogue of the octahedron]], and each of its four orthogonal central hyperplanes is an octahedron. The only planar regular polygons found in the 16-cell are face triangles and central plane squares, but the 16-cell also contains a skew regular octagon, its [[W:Petrie polygon|Petrie polygon]]. The chords of this regular octagon, which lies skew in 4-space, are those given above for the 16-cell, as opposed to those for the cube or the regular octagon in the plane. The 16-cell is a construct of 3 Petrie octagons which share the same 8 vertices but have disjoint sets of 8 edges each. The regular octad has higher symmetry in 4-space than it does in 2-space. The 16-cell is the 4-orthoplex, the simplest regular 4-polytope after the [[5-cell|4-simplex]]. All the larger regular 4-polytopes, including the 120-cell, are compounds of the 16-cell. The regular octagon exhibits this high symmetry only when embedded in 4-space at the vertices of the 16-cell. The 16-cell constitutes an [[W:Orthonormal basis|orthonormal basis]] for the choice of a 4-dimensional Cartesian reference frame, because its vertices define four orthogonal axes. The eight vertices of a unit-radius 16-cell are (±1, 0, 0, 0), (0, ±1, 0, 0), (0, 0, ±1, 0), (0, 0, 0, ±1). All vertices are connected by <small><math>\sqrt{2}</math></small> edges except opposite pairs. The vertex coordinates of the 16-cell form 6 central squares lying in 6 pairwise [[W:Orthogonal|orthogonal]] coordinate planes. Great squares in ''opposite'' planes that do not share an axis (e.g. in the ''xy'' and ''wz'' planes) are completely disjoint (they do not intersect at any vertices). These planes are [[W:Completely orthogonal|completely orthogonal]].{{Efn|name=Six orthogonal planes of the Cartesian basis}} Since this unit-radius coordinate system is convenient, let us derive the unit-radius 16-cell by skewing a unit-radius planar octagon, which has chords of length: :<math>r_1=\sqrt{2-\sqrt{2}} \approx 0.76537,r_2=\sqrt{2},r_3=\sqrt{2+\sqrt{2}} \approx 1.84776,r_4=2</math> We will need a planar octagon with rigid <math>r_2</math> chords, rather than one with rigid <math>r_1</math> edges. The octagon's <math>r_2</math> chords form two disjoint squares, which we can reposition in 3-space to form a cube by making them parallel, and in 4-space to form a 16-cell by making them completely orthogonal. The <math>r_2</math> chords form two disjoint great squares, visible in the orthogonal projection. These central squares are completely orthogonal: both parallel and perpendicular to each other. A ''simple'' rotation of the 16-cell in ''one'' of these two central planes rotates that square like a wheel, while the other square does not move. The four vertices of the rotating square orbit on a great circle. The <math>r_1</math> chords form a Petrie polygon which zig-zags back and forth between the two completely orthogonal <math>r_2</math> squares. The <math>r_3</math> chords form a circular helix, visible as a skew {8/3} polygram in the orthogonal projection. A ''double'' rotation of the 16-cell, in ''both'' of the two completely orthogonal <math>r_2</math> central square planes at once, moves the vertices along the circular helix over the <math>r_3</math> chords. [[W:Rotations in 4-dimensional Euclidean space|Rotations in 4-dimensional Euclidean space]] can be seen as the composition of two 2-dimensional rotations in completely orthogonal planes. The general rotation in 4-space is a double rotation in pairs of completely orthogonal planes. Two completely orthogonal planes are called invariant planes of the rotation when all points in the plane rotate on circles that remain in the plane, even as the whole plane tilts sideways (like a coin flipping) into another plane. The two completely orthogonal rotations of each plane (like a wheel, and like a coin flipping) are simultaneous but independent, in that they are not geometrically constrained to turn at the same rate. However, the most circular kind of rotation (as opposed to an elliptical double rotation of a rigid spherical object) occurs when the invariant planes do rotate through the same angle in the same time interval. Such equi-angled double rotations are called [[w:SO(4)#Isoclinic_rotations|isoclinic]], also [[w:William_Kingdon_Clifford|Clifford]] displacements. The 16-cell is the simplest possible frame in which to [[16-cell#Rotations|observe 4-dimensional rotations]] because its characteristic isoclinic rotations feature a single pair of invariant rotation planes. In the 16-cell an isoclinic rotation by 90° in any pair of invariant completely orthogonal square central planes takes every square central plane to its completely orthogonal square central plane in a twisting displacment, as they tilt sideways 90° into each other's plane while rotating 90° internally. All the vertices move at once on separate circular [[w:Geodesic|geodesics]], displaced 90° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. When the 90° isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 90°, but from the new orientation in a direction orthogonal to its first 90° displacement. After 360° of rotation each vertex reaches its antipodal position. The trajectory of each vertex over each 90° isoclinic rotational displacement is a one-eighth segment of its geodesic orbit. Its entire orbit traces a circular helix in 4-space over eight <math>r_3</math> chords, and also traces a great circle twice over the four <math>r_2</math> chords of one of the two moving invariant rotation planes. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once and returns to its original position, and the 16-cell returns to its original orientation. == Hypercubes == The long diameter of the unit-edge [[W:Hypercube|hypercube]] of dimension <small><math>n</math></small> is <small><math>\sqrt{n}</math></small>, so the unit-edge [[w:Tesseract|4-hypercube, the 16-point (8-cell) tesseract,]] has chords: :<math>r_1=\sqrt{1},r_2=\sqrt{2},r_3=\sqrt{3},r_4=\sqrt{4}</math> Uniquely in its 4-dimensional case, the hypercube's edge length equals its radius, like the hexagon. We call such polytopes ''radially equilateral'', because they can be constructed from equilateral triangles which meet at their center, each contributing two radii and an edge. The cuboctahedron and the 24-cell are also radially equilateral. The [[W:Tesseract|tesseract]] is the [[W:Regular convex 4-polytope|regular convex 4-polytope]] with [[W:Schläfli symbol|Schläfli symbol]] {4,3,3}. It has 16 vertices, 32 edges, 24 square faces, and 8 cube cells. It is the four-dimensional analogue of the cube. The tesseract is the [[W:Dual polytope|dual polytope]] of the 16-cell. They have the same Petrie polygon, the regular octagon, but the tesseract contains 2 disjoint instances and 4 distinct instances of the skew octagon. We can construct the tesseract by skewing two planar octagons. Because the tesseract is radially equilateral (unlike the 16-cell), we start with our original octagon of unit-edge length, rather than the octagon of edge length <small><math>\sqrt{2}</math></small> that we needed to build the unit-radius 16-cell. For our tesseract construction we skew each planar octagon into a cube, so we have a compound of two completely orthogonal cubes. Provided the planes were completely orthogonal in 4-space and we skewed them both the same way, the 16 vertices will be the vertices of a tesseract with half of its 32 edges missing. The 16-point tesseract is the convex hull of a compound of two 8-point 16-cells, in exact dimensional analogy to the way the 8-point cube is the convex hull of a [[W:Stellated octahedron|compound of two regular 4-point tetrahedra]]. The [[W:Demihypercube|demihypercubes]] occupy alternate vertices of the hypercubes. The diagonals of the square faces of the unit-radius tesseract are the <small><math>\sqrt{2}</math></small> edges of two unit-radius 16-cells, which are also the edges of the square central planes. Because the tesseract contains two 16-cells in alternate positions it has two sets of 6 orthogonal square central planes. Two angles are required to specify the relationship between two planes in 4-space. Pairs of planes within each 16-cell are 90° apart in one angle, and either 0° or 90° apart in the other angle. They are 90° apart in both angles if and only if they are completely orthogonal planes, 90° apart by isoclinic rotation, with no vertices in common and their corresponding vertices 180° apart. Otherwise they are 0° apart in one of the angles, 90° apart by simple rotation with their corresponding vertices 90° apart, and they intersect in one axis and lie in a common 3-dimensional hyperplane.{{Efn|A double rotation in which one of the two angles of rotation is 0°, so that one of the completely orthogonal invariant planes does not rotate, is called a simple rotation. Ordinary rotations observed in a 3-dimensional space are simple rotations.}} A pair of square central planes from alternate 16-cells are 60° apart by isoclinic rotation, with their corresponding vertices 120° apart. The planes are not orthogonal or parallel, so they intersect in a line somewhere, but they have no vertices in common, they have no 3-dimensional hyperplane in common, and they cannot reach each other by simple rotation. Such pairs of objects are called [[W:Clifford parallel|Clifford parallel]] because all their corresponding pairs of vertices are the same distance apart, although they are not parallel in the usual sense, because they have a common center. Not only the alternate 16-cells' corresponding square central planes, but also the 16-cells themselves, are Clifford parallel objects. We can rotate the tesseract isoclinically the way we rotated the 16-cell, by 90° in two completely orthogonal invariant square central planes, with the same effect on both alternate 16-cells. In the course of a 720° isoclinic rotation in invariant square central planes each vertex departs from all 8 vertex positions of its 16-cell just once and returns to its original position, but it does not visit the vertex positions of the other 16-cell. The skew octagon geodesic orbits of the 16 vertices are disjoint circular helixes, and those 16 circular helixes are Clifford parallel objects. == The 24-cell == In 2-space we have the radially equilateral 6-point hexagon. In 3-space we have the radially equilateral 12-point cuboctahedron, with 4 hexagonal central planes. In 4-space we have the radially equilateral 24-point 24-cell, with 4 cuboctahedral central hyperplanes and 16 hexagonal central planes. Great hexagons are a rounder choice than great squares for the invariant rotation planes in which to rotate a 4-polytope isoclinically. The complete hexagonal isoclinic revolution requires 720° like the square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 90° each. ... == The 600-cell == ... == Finally the 120-cell == ... == Conclusions == Fontaine and Hurley's discovery is more than a formula for the reciprocal of a regular ''n''-polygon diagonal. It also yields the discrete sequence of isocline chords of the distinct isoclinic rotation characteristic of a ''d''-dimensional regular polytope. The characteristic rotational chord sequence of the ''d''-polytope can be represented geometrically in two dimensions on a distinct star polygon, but it lies on a geodesic circle through ''d''-dimensional space. Fontaine and Hurley discovered the geodesic topology of polytopes generally. Their procedure will reveal the geodesics of arbitrary non-uniform polytopes, since it can be applied to a polytope of any dimensionality and irregularity, by first fitting the polytope to the smallest regular polygon whose chords include its chords. Fontaine and Hurley's discovery of a chordal formula for isoclinic rotations closes the circuit on Kappraff and Adamson's discovery of a rotational connection between dynamical systems, Steinbach's golden fields, and Coxeter's Euclidean geometry of ''n'' dimensions. Application of the Fontaine and Hurley procedure in higher-dimensional spaces demonstrates why the connection exists: because polytope sequences generally, from Steinbach's golden polygon chord sequences, to chord sequences in isoclinic rotation helixes, to subsumption relations in the sequence of regular 4-polytopes, arise as expressions of the reflections and rotations of distinct Coxeter symmetry groups, when those various groups interact. == Appendix: Sequence of regular 4-polytopes == {{Regular convex 4-polytopes|wiki=W:|columns=7}} == Notes == {{Notelist}} == Citations == {{Reflist}} == References == {{Refbegin}} * {{Cite journal | last=Steinbach | first=Peter | year=1997 | title=Golden fields: A case for the Heptagon | journal=Mathematics Magazine | volume=70 | issue=Feb 1997 | pages=22–31 | doi=10.1080/0025570X.1997.11996494 | jstor=2691048 | ref={{SfnRef|Steinbach|1997}} }} * {{Cite journal | last=Steinbach | first=Peter | year=2000 | title=Sections Beyond Golden| journal=Bridges: Mathematical Connections in Art, Music and Science | issue=2000 | pages=35-44 | url=https://archive.bridgesmathart.org/2000/bridges2000-35.pdf | ref={{SfnRef|Steinbach|2000}}}} * {{Cite journal | last1=Kappraff | first1=Jay | last2=Jablan | first2=Slavik | last3=Adamson | first3=Gary | last4=Sazdanovich | first4=Radmila | year=2004 | title=Golden Fields, Generalized Fibonacci Sequences, and Chaotic Matrices | journal=Forma | volume=19 | pages=367-387 | url=https://archive.bridgesmathart.org/2005/bridges2005-369.pdf | ref={{SfnRef|Kappraff, Jablan, Adamson & Sazdanovich|2004}} }} * {{Cite journal | last1=Kappraff | first1=Jay | last2=Adamson | first2=Gary | year=2004 | title=Polygons and Chaos | journal=Dynamical Systems and Geometric Theories | url=https://archive.bridgesmathart.org/2001/bridges2001-67.pdf | ref={{SfnRef|Kappraff & Adamson|2004}} }} * {{Cite journal | last1=Fontaine | first1=Anne | last2=Hurley | first2=Susan | year=2006 | title=Proof by Picture: Products and Reciprocals of Diagonal Length Ratios in the Regular Polygon | journal=Forum Geometricorum | volume=6 | pages=97-101 | url=https://scispace.com/pdf/proof-by-picture-products-and-reciprocals-of-diagonal-length-1aian8mgp9.pdf }} {{Refend}} 2xhk6juo1p9q99g8y0ey8tqdg16wnd4 2809779 2809770 2026-05-17T00:12:42Z Dc.samizdat 2856930 /* The 8-point regular polytopes */ 2809779 wikitext text/x-wiki {{align|center|David Brooks Christie}} {{align|center|dc@samizdat.org}} {{align|center|Draft in progress}} {{align|center|January 2026 - April 2026}} <blockquote>Steinbach discovered the formula for the ratios of diagonal to side in the regular polygons. Fontaine and Hurley extended this result, discovering a formula for the reciprocal of a regular polygon chord derived geometrically from the chord's star polygon. We observe that these findings in plane geometry apply more generally, to polytopes of any dimensionality. Fontaine and Hurley's geometric procedure for finding the reciprocals of the chords of a regular polygon from their star polygons also finds the rotational geodesics of any polytope of any dimensionality.</blockquote> == Introduction == Steinbach discovered the Diagonal Product Formula and the Golden Fields family of ratios of diagonal to side in the regular polygons. He showed how this family extends beyond the pentagon {5} with its well-known golden bisection proportional to 𝜙, finding that the heptagon {7} has an analogous trisection, the nonagon {9} has an analogous quadrasection, and the hendecagon {11} has an analogous pentasection, an extended family of golden proportions with quasiperiodic properties. Kappraff and Adamson extended these findings in plane geometry to a theory of Generalized Fibonacci Sequences, showing that the Golden Fields not only do not end with the hendecagon, they form an infinite number of periodic trajectories when operated on by the Mandelbrot operator. They found a relation between the edges of star polygons and dynamical systems in the state of chaos, revealing a connection between chaos theory, number, and rotations in Coxeter Euclidean geometry. Fontaine and Hurley examined Steinbach's finding that the length of each chord of a regular polygon is both the product of two chords and the sum of a set of smaller chords, so that in rotations to add is to multiply. They illustrated Steinbach's sets of additive chords lying parallel to each other in the plane (pointing in the same direction), and by applying Steinbach's formula more generally they found another summation relation of signed parallel chords (pointing in opposite directions) which relates each chord length to its reciprocal, and relates the summation to a distinct star polygon rotation. We examine these remarkable findings (which stem from study of the chords of humble regular polygons) in higher-dimensional spaces, specifically in the chords, polygons and rotations of the [[120-cell]], the largest four-dimensional regular convex polytope. == Visualizing the 120-cell == {| class="wikitable floatright" width="400" |style="vertical-align:top"|[[File:120-cell.gif|200px]]<br>Orthographic projection of the 600-point 120-cell <small><math>\{5,3,3\}</math></small> performing a [[W:SO(4)#Geometry of 4D rotations|simple rotation]].{{Sfn|Hise|2011|loc=File:120-cell.gif|ps=; "Created by Jason Hise with Maya and Macromedia Fireworks.

Therefore even though it is translucent, only its outer surface is visible. The complex interior parts of the 120-cell, all its inscribed 5-cells, 16-cells, 8-cells, 24-cells, 600-cells and its much larger inventory of polyhedra, are completely invisible in this view, as none of their edges are rendered at all. |style="vertical-align:top"|[[File:Ortho solid 016-uniform polychoron p33-t0.png|200px]]<br>Orthographic projection of the 600-point [[W:Great grand stellated 120-cell|great grand stellated 120-cell]] <small><math>\{\tfrac{5}{2},3,3\}</math></small>.{{Sfn|Ruen: Great grand stellated 120-cell|2007}} The 120-cell is its convex hull.

The 120-cell is the convex hull of a regular [[120-cell#Relationships among interior polytopes|compound of each of the 6 regular convex 4-polytopes]]. They are the [[5-cell|5-point (5-cell) 4-simplex]], the [[16-cell|8-point (16-cell) 4-orthoplex]], the [[W:Tesseract|16-point (8-cell) tesseract]], the [[24-cell|24-point (24-cell)]], the [[600-cell|120-point (600-cell)]], and the [[120-cell|600-point (120-cell)]]. The 120-cell is the convex hull of a compound of 120 disjoint regular 5-cells, of 75 disjoint 16-cells, of 25 disjoint 24-cells, and of 5 disjoint 600-cells. The 120-cell contains an even larger inventory of irregular polytopes, created by the intersection of multiple instances of these component regular 4-polytopes. Many are quite unexpected, because they do not occur as components of any regular polytope smaller than the 120-cell. As just one example among the [[120-cell#Concentric hulls|sections of the 120-cell]], there is an irregular 24-point polyhedron with 16 triangle faces and 4 nonagon {9} faces.{{Sfn|Moxness|}} Most renderings of the 120-cell, like the rotating projection here, only illustrate its outer surface, which is a honeycomb of face-bonded dodecahedral cells. Only the objects in its 3-dimensional surface are rendered, namely the 120 dodecahedra, their pentagon faces, and their edges. Although the 120-cell has chords of 30 distinct lengths, in this kind of simplified rendering only the 120-cell's own edges (its shortest chord) are shown. Its 29 interior chords, the edges of objects in the interior of the 120-cell, are not rendered, so interior objects are not visible at all. Visualizing the complete interior of the 600-vertex 120-cell in a single image is impractical because of its complexity. Only four 120-cell edges are incident at each vertex, but [[120-cell#Chords|600 chords (of all 30 lengths)]] are incident at ''each'' vertex. == Compounds in the 120-cell == The 8-point (16-cell), not the 5-point (5-cell), is the smallest building block; it compounds to every larger regular 4-polytope. The 5-point (5-cell) does compound to the 600-point (120-cell), but it does not fit into any smaller regular 4-polytope. The 8-point (16-cell) compounds by 2 in the 16-point (8-cell), and by 3 in the 24-point (24-cell). The 16-point (8-cell) compounds in the 24-point (24-cell) by 3 non-disjoint instances of itself, with each of the 24 vertices shared by two 16-point (8-cells). The 24-point (24-cell) compounds by 5 disjoint instances of itself in the 120-point (600-cell), and the 120-point (600-cell) compounds by 5 disjoint instances of itself in the 600-point (120-cell). The 24-point (24-cell) also compounds by <math>5^2</math> non-disjoint instances of itself in the 120-point (600-cell); it compounds in 5 disjoint instances of itself, 10 (not 5) different ways. Whichever set of 5 disjoint 24-point (24-cells) are assembled, the resulting 120-point (600-cell) contains 25 distinct 24-point (24-cells), not just 5 (or 10). This implies that 15 disjoint 8-point (16-cells) will construct a 120-point (600-cell), which will contain 75 distinct 8-point (16-cells). The 600-point (120-cell) is 5 disjoint 120-point (600-cells), just 2 different ways (not 5 or 10 ways), so it is 10 distinct 120-point (600-cells). This implies that the 8-point (16-cell) compounds by 3 times <math>5^2</math> (75) disjoint instances of itself in the 600-point (120-cell), which contains <math>3^2</math> times <math>5^2</math> (225) distinct instances of the 24-point (24-cell), and <math>3^3</math> times <math>5^2</math> (675) distinct instances of the 8-point (16-cell). These facts were discovered painstakingly by various researchers, and no one has found a general rule governing subsumption relations among regular polytopes. The reasons for some of their numeric incidence relations are far from obvious. [[W:Pieter Hendrik Schoute|Schoute]] was the first to see that the 120-point (600-cell) is a compound of 5 24-point (24-cells) ''10 different ways'', and after he saw it a hundred years lapsed until Denney, Hooker, Johnson, Robinson, Butler & Claiborne proved his result, and showed why.{{Sfn|Denney, Hooker, Johnson, Robinson, Butler & Claiborne|2020|loc=''The geometry of H4 polytopes''}} So much for the compounds of 16-cells. The 120-cell is also the convex hull of the compound of 120 disjoint regular 5-cells. That stellated compound (without its convex hull of 120-cell edges) is the [[w:Great_grand_stellated_120-cell|great grand stellated 120-cell]] illustrated above, the final regular [[W:Stellation|stellation]] of the 120-cell, and the only [[W:Schläfli-Hess polychoron|regular star 4-polytope]] to have the 120-cell for its convex hull. The edges of the great grand stellated 120-cell are <math>\phi^6</math> as long as those of its 120-cell [[W:List of polyhedral stellations#Stellation process|stellation core]] deep inside. The compound of 120 disjoint 5-point (5-cells) can be seen to be equivalent to the compound of 5 disjoint 120-point (600-cells), as follows. Beginning with a single 120-point (600-cell), expand each vertex into a regular 5-cell, by adding 4 new equidistant vertices, such that the 5 vertices form a regular 5-cell inscribed in the 3-sphere. The 120 5-cells are disjoint, and the 600 vertices form 5 disjoint 120-point (600-cells): a 120-cell. == Thirty distinguished distances == The 30 numbers listed in the table are all-important in Euclidean geometry. A case can be made on symmetry grounds that their squares are the 30 most important numbers between 0 and 4. The 30 rows of the table are the 30 distinct [[120-cell#Geodesic rectangles|chord lengths of the unit-radius 120-cell]], the largest regular convex 4-polytope. Since the 120-cell subsumes all smaller regular polytopes, its 30 chords are the complete chord set of all the regular polytopes that can be constructed in the first four dimensions of Euclidean space, except for regular polygons of more than 15 sides. {| class="wikitable" style="white-space:nowrap;text-align:center" !rowspan=2|<math>c_t</math> !rowspan=2|arc

regular polytopes == In 2-space we have the regular 8-point octagon, in 3-space the regular 8-point cube, and in 4-space the regular 8-point [[16-cell]]. A planar octagon with rigid edges of unit length has chords of length: :<math>r_1=1,r_2=\sqrt{2+\sqrt{2}} \approx 1.84776,r_3=1+\sqrt{2} \approx 2.41421,r_4=\sqrt{4 + \sqrt{8}} \approx 2.61313</math> The chord ratio <math>r_3=1+\sqrt{2}</math> is a geometrical proportion, the [[W:Silver ratio|silver ratio]]. Fontaine and Hurley's procedure for obtaining the reciprocal of a chord tells us that: :<math>r_3-r_1-r_1=1/r_3 \approx 0.41421</math> Note that <math>1/r_3=\sqrt{2}-1=r_3-2</math>. If we embed this planar octagon in 3-space, we can make it skew, repositioning its vertices so that each is one unit-edge length distant from three others instead of two others, at the vertices of a unit-edge cube with chords of length: :<math>r_1=1, r_2=\sqrt{2}, r_3=\sqrt{3}, r_4=\sqrt{2}</math> If we embed this cube in 4-space, we can skew it some more, repositioning its vertices so that each is one unit-edge length distant from six others instead of three others, at the vertices of a unit-edge 4-polytope with chords of length: :<math>r_1=1,r_2=1,r_3=1,r_4=\sqrt{2}</math> All of its chords except its long diameters are the same unit length as its edge. In fact they are its 24 edges, and it is a 16-cell of radius <small><math>1/\sqrt{2}</math></small>. [[File:octagon16cell.png|thumb|Orthogonal projection of a regular 16-cell to the [[16-cell#Projections|B<sub>4</sub> Coxeter plane]]. Only its edges are shown; its long diameter chords are not drawn. All 24 edges are the same length. Only the edges of the two disjoint squares lie parallel to the projection plane, in completely orthogonal central planes.]] The [[16-cell]] is the [[W:Regular convex 4-polytope|regular convex 4-polytope]] with [[W:Schläfli symbol|Schläfli symbol]] {3,3,4}. It has 8 vertices, 24 edges, 32 equilateral triangle faces, and 16 regular tetrahedron cells. It is the [[16-cell#Octahedral dipyramid|four-dimensional analogue of the octahedron]], and each of its four orthogonal central hyperplanes is an octahedron. The only planar regular polygons found in the 16-cell are face triangles and central plane squares, but the 16-cell also contains a skew regular octagon, its [[W:Petrie polygon|Petrie polygon]]. The chords of this regular octagon, which lies skew in 4-space, are those given above for the 16-cell, as opposed to those for the cube or the regular octagon in the plane. The 16-cell is a construct of 3 Petrie octagons which share the same 8 vertices but have disjoint sets of 8 edges each. The regular octad has higher symmetry in 4-space than it does in 2-space. The 16-cell is the 4-orthoplex, the simplest regular 4-polytope after the [[5-cell|4-simplex]]. All the larger regular 4-polytopes, including the 120-cell, are compounds of the 16-cell. The regular octagon exhibits this high symmetry only when embedded in 4-space at the vertices of the 16-cell. The 16-cell constitutes an [[W:Orthonormal basis|orthonormal basis]] for the choice of a 4-dimensional Cartesian reference frame, because its vertices define four orthogonal axes. The eight vertices of a unit-radius 16-cell are (±1, 0, 0, 0), (0, ±1, 0, 0), (0, 0, ±1, 0), (0, 0, 0, ±1). All vertices are connected by <small><math>\sqrt{2}</math></small> edges except opposite pairs. The vertex coordinates of the 16-cell form 6 central squares lying in 6 pairwise [[W:Orthogonal|orthogonal]] coordinate planes. Great squares in ''opposite'' planes that do not share an axis (e.g. in the ''xy'' and ''wz'' planes) are completely disjoint (they do not intersect at any vertices). These planes are [[W:Completely orthogonal|completely orthogonal]].{{Efn|name=Six orthogonal planes of the Cartesian basis}} Since this unit-radius coordinate system is convenient, let us derive the unit-radius 16-cell by skewing a unit-radius planar octagon, which has chords of length: :<math>r_1=\sqrt{2-\sqrt{2}} \approx 0.76537,r_2=\sqrt{2},r_3=\sqrt{2+\sqrt{2}} \approx 1.84776,r_4=2</math> We will need a planar octagon with rigid <math>r_2</math> chords, rather than one with rigid <math>r_1</math> edges. The octagon's <math>r_2</math> chords form two disjoint great squares, visible in the orthogonal projection, which we can reposition in 3-space to form a cube by making them parallel, and in 4-space to form a 16-cell by making them completely orthogonal. In the 16-cell the two disjoint great squares are both parallel and perpendicular to each other. A ''simple'' rotation of the 16-cell in ''one'' of those two central planes rotates that square like a wheel, while the other square does not move. The four vertices of the rotating square orbit on a great circle. The <math>r_1</math> chords form a Petrie polygon which zig-zags back and forth between the two completely orthogonal <math>r_2</math> squares. The <math>r_3</math> chords form a circular helix, visible as a skew {8/3} polygram in the orthogonal projection. A ''double'' rotation of the 16-cell, in ''both'' of the two completely orthogonal <math>r_2</math> central square planes at once, moves the vertices along the circular helix over the <math>r_3</math> chords. [[W:Rotations in 4-dimensional Euclidean space|Rotations in 4-dimensional Euclidean space]] can be seen as the composition of two 2-dimensional rotations in completely orthogonal planes. The general rotation in 4-space is a double rotation in pairs of completely orthogonal planes. Two completely orthogonal planes are called invariant planes of the rotation when all points in the plane rotate on circles that remain in the plane, even as the whole plane tilts sideways (like a coin flipping) into another plane. The two completely orthogonal rotations of each plane (like a wheel, and like a coin flipping) are simultaneous but independent, in that they are not geometrically constrained to turn at the same rate. However, the most circular kind of rotation (as opposed to an elliptical double rotation of a rigid spherical object) occurs when the invariant planes do rotate through the same angle in the same time interval. Such equi-angled double rotations are called [[w:SO(4)#Isoclinic_rotations|isoclinic]], also [[w:William_Kingdon_Clifford|Clifford]] displacements. The 16-cell is the simplest possible frame in which to [[16-cell#Rotations|observe 4-dimensional rotations]] because its characteristic isoclinic rotations feature a single pair of invariant rotation planes. In the 16-cell an isoclinic rotation by 90° in any pair of invariant completely orthogonal square central planes takes every square central plane to its completely orthogonal square central plane in a twisting displacment, as they tilt sideways 90° into each other's plane while rotating 90° internally. All the vertices move at once on separate circular [[w:Geodesic|geodesics]], displaced 90° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. When the 90° isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 90°, but from the new orientation in a direction orthogonal to its first 90° displacement. After 360° of rotation each vertex reaches its antipodal position. The trajectory of each vertex over each 90° isoclinic rotational displacement is a one-eighth segment of its geodesic orbit. Its entire orbit traces a circular helix in 4-space over eight <math>r_3</math> chords, and also traces a great circle twice over the four <math>r_2</math> chords of one of the two moving invariant rotation planes. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once and returns to its original position, and the 16-cell returns to its original orientation. == Hypercubes == The long diameter of the unit-edge [[W:Hypercube|hypercube]] of dimension <small><math>n</math></small> is <small><math>\sqrt{n}</math></small>, so the unit-edge [[w:Tesseract|4-hypercube, the 16-point (8-cell) tesseract,]] has chords: :<math>r_1=\sqrt{1},r_2=\sqrt{2},r_3=\sqrt{3},r_4=\sqrt{4}</math> Uniquely in its 4-dimensional case, the hypercube's edge length equals its radius, like the hexagon. We call such polytopes ''radially equilateral'', because they can be constructed from equilateral triangles which meet at their center, each contributing two radii and an edge. The cuboctahedron and the 24-cell are also radially equilateral. The [[W:Tesseract|tesseract]] is the [[W:Regular convex 4-polytope|regular convex 4-polytope]] with [[W:Schläfli symbol|Schläfli symbol]] {4,3,3}. It has 16 vertices, 32 edges, 24 square faces, and 8 cube cells. It is the four-dimensional analogue of the cube. The tesseract is the [[W:Dual polytope|dual polytope]] of the 16-cell. They have the same Petrie polygon, the regular octagon, but the tesseract contains 2 disjoint instances and 4 distinct instances of the skew octagon. We can construct the tesseract by skewing two planar octagons. Because the tesseract is radially equilateral (unlike the 16-cell), we start with our original octagon of unit-edge length, rather than the octagon of edge length <small><math>\sqrt{2}</math></small> that we needed to build the unit-radius 16-cell. For our tesseract construction we skew each planar octagon into a cube, so we have a compound of two completely orthogonal cubes. Provided the planes were completely orthogonal in 4-space and we skewed them both the same way, the 16 vertices will be the vertices of a tesseract with half of its 32 edges missing. The 16-point tesseract is the convex hull of a compound of two 8-point 16-cells, in exact dimensional analogy to the way the 8-point cube is the convex hull of a [[W:Stellated octahedron|compound of two regular 4-point tetrahedra]]. The [[W:Demihypercube|demihypercubes]] occupy alternate vertices of the hypercubes. The diagonals of the square faces of the unit-radius tesseract are the <small><math>\sqrt{2}</math></small> edges of two unit-radius 16-cells, which are also the edges of the square central planes. Because the tesseract contains two 16-cells in alternate positions it has two sets of 6 orthogonal square central planes. Two angles are required to specify the relationship between two planes in 4-space. Pairs of planes within each 16-cell are 90° apart in one angle, and either 0° or 90° apart in the other angle. They are 90° apart in both angles if and only if they are completely orthogonal planes, 90° apart by isoclinic rotation, with no vertices in common and their corresponding vertices 180° apart. Otherwise they are 0° apart in one of the angles, 90° apart by simple rotation with their corresponding vertices 90° apart, and they intersect in one axis and lie in a common 3-dimensional hyperplane.{{Efn|A double rotation in which one of the two angles of rotation is 0°, so that one of the completely orthogonal invariant planes does not rotate, is called a simple rotation. Ordinary rotations observed in a 3-dimensional space are simple rotations.}} A pair of square central planes from alternate 16-cells are 60° apart by isoclinic rotation, with their corresponding vertices 120° apart. The planes are not orthogonal or parallel, so they intersect in a line somewhere, but they have no vertices in common, they have no 3-dimensional hyperplane in common, and they cannot reach each other by simple rotation. Such pairs of objects are called [[W:Clifford parallel|Clifford parallel]] because all their corresponding pairs of vertices are the same distance apart, although they are not parallel in the usual sense, because they have a common center. Not only the alternate 16-cells' corresponding square central planes, but also the 16-cells themselves, are Clifford parallel objects. We can rotate the tesseract isoclinically the way we rotated the 16-cell, by 90° in two completely orthogonal invariant square central planes, with the same effect on both alternate 16-cells. In the course of a 720° isoclinic rotation in invariant square central planes each vertex departs from all 8 vertex positions of its 16-cell just once and returns to its original position, but it does not visit the vertex positions of the other 16-cell. The skew octagon geodesic orbits of the 16 vertices are disjoint circular helixes, and those 16 circular helixes are Clifford parallel objects. == The 24-cell == In 2-space we have the radially equilateral 6-point hexagon. In 3-space we have the radially equilateral 12-point cuboctahedron, with 4 hexagonal central planes. In 4-space we have the radially equilateral 24-point 24-cell, with 4 cuboctahedral central hyperplanes and 16 hexagonal central planes. Great hexagons are a rounder choice than great squares for the invariant rotation planes in which to rotate a 4-polytope isoclinically. The complete hexagonal isoclinic revolution requires 720° like the square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 90° each. ... == The 600-cell == ... == Finally the 120-cell == ... == Conclusions == Fontaine and Hurley's discovery is more than a formula for the reciprocal of a regular ''n''-polygon diagonal. It also yields the discrete sequence of isocline chords of the distinct isoclinic rotation characteristic of a ''d''-dimensional regular polytope. The characteristic rotational chord sequence of the ''d''-polytope can be represented geometrically in two dimensions on a distinct star polygon, but it lies on a geodesic circle through ''d''-dimensional space. Fontaine and Hurley discovered the geodesic topology of polytopes generally. Their procedure will reveal the geodesics of arbitrary non-uniform polytopes, since it can be applied to a polytope of any dimensionality and irregularity, by first fitting the polytope to the smallest regular polygon whose chords include its chords. Fontaine and Hurley's discovery of a chordal formula for isoclinic rotations closes the circuit on Kappraff and Adamson's discovery of a rotational connection between dynamical systems, Steinbach's golden fields, and Coxeter's Euclidean geometry of ''n'' dimensions. Application of the Fontaine and Hurley procedure in higher-dimensional spaces demonstrates why the connection exists: because polytope sequences generally, from Steinbach's golden polygon chord sequences, to chord sequences in isoclinic rotation helixes, to subsumption relations in the sequence of regular 4-polytopes, arise as expressions of the reflections and rotations of distinct Coxeter symmetry groups, when those various groups interact. == Appendix: Sequence of regular 4-polytopes == {{Regular convex 4-polytopes|wiki=W:|columns=7}} == Notes == {{Notelist}} == Citations == {{Reflist}} == References == {{Refbegin}} * {{Cite journal | last=Steinbach | first=Peter | year=1997 | title=Golden fields: A case for the Heptagon | journal=Mathematics Magazine | volume=70 | issue=Feb 1997 | pages=22–31 | doi=10.1080/0025570X.1997.11996494 | jstor=2691048 | ref={{SfnRef|Steinbach|1997}} }} * {{Cite journal | last=Steinbach | first=Peter | year=2000 | title=Sections Beyond Golden| journal=Bridges: Mathematical Connections in Art, Music and Science | issue=2000 | pages=35-44 | url=https://archive.bridgesmathart.org/2000/bridges2000-35.pdf | ref={{SfnRef|Steinbach|2000}}}} * {{Cite journal | last1=Kappraff | first1=Jay | last2=Jablan | first2=Slavik | last3=Adamson | first3=Gary | last4=Sazdanovich | first4=Radmila | year=2004 | title=Golden Fields, Generalized Fibonacci Sequences, and Chaotic Matrices | journal=Forma | volume=19 | pages=367-387 | url=https://archive.bridgesmathart.org/2005/bridges2005-369.pdf | ref={{SfnRef|Kappraff, Jablan, Adamson & Sazdanovich|2004}} }} * {{Cite journal | last1=Kappraff | first1=Jay | last2=Adamson | first2=Gary | year=2004 | title=Polygons and Chaos | journal=Dynamical Systems and Geometric Theories | url=https://archive.bridgesmathart.org/2001/bridges2001-67.pdf | ref={{SfnRef|Kappraff & Adamson|2004}} }} * {{Cite journal | last1=Fontaine | first1=Anne | last2=Hurley | first2=Susan | year=2006 | title=Proof by Picture: Products and Reciprocals of Diagonal Length Ratios in the Regular Polygon | journal=Forum Geometricorum | volume=6 | pages=97-101 | url=https://scispace.com/pdf/proof-by-picture-products-and-reciprocals-of-diagonal-length-1aian8mgp9.pdf }} {{Refend}} l7scyxbdp7138k9g6ntou7brp9nh66o 2809780 2809779 2026-05-17T00:17:39Z Dc.samizdat 2856930 /* The 8-point regular polytopes */ 2809780 wikitext text/x-wiki {{align|center|David Brooks Christie}} {{align|center|dc@samizdat.org}} {{align|center|Draft in progress}} {{align|center|January 2026 - April 2026}} <blockquote>Steinbach discovered the formula for the ratios of diagonal to side in the regular polygons. Fontaine and Hurley extended this result, discovering a formula for the reciprocal of a regular polygon chord derived geometrically from the chord's star polygon. We observe that these findings in plane geometry apply more generally, to polytopes of any dimensionality. Fontaine and Hurley's geometric procedure for finding the reciprocals of the chords of a regular polygon from their star polygons also finds the rotational geodesics of any polytope of any dimensionality.</blockquote> == Introduction == Steinbach discovered the Diagonal Product Formula and the Golden Fields family of ratios of diagonal to side in the regular polygons. He showed how this family extends beyond the pentagon {5} with its well-known golden bisection proportional to 𝜙, finding that the heptagon {7} has an analogous trisection, the nonagon {9} has an analogous quadrasection, and the hendecagon {11} has an analogous pentasection, an extended family of golden proportions with quasiperiodic properties. Kappraff and Adamson extended these findings in plane geometry to a theory of Generalized Fibonacci Sequences, showing that the Golden Fields not only do not end with the hendecagon, they form an infinite number of periodic trajectories when operated on by the Mandelbrot operator. They found a relation between the edges of star polygons and dynamical systems in the state of chaos, revealing a connection between chaos theory, number, and rotations in Coxeter Euclidean geometry. Fontaine and Hurley examined Steinbach's finding that the length of each chord of a regular polygon is both the product of two chords and the sum of a set of smaller chords, so that in rotations to add is to multiply. They illustrated Steinbach's sets of additive chords lying parallel to each other in the plane (pointing in the same direction), and by applying Steinbach's formula more generally they found another summation relation of signed parallel chords (pointing in opposite directions) which relates each chord length to its reciprocal, and relates the summation to a distinct star polygon rotation. We examine these remarkable findings (which stem from study of the chords of humble regular polygons) in higher-dimensional spaces, specifically in the chords, polygons and rotations of the [[120-cell]], the largest four-dimensional regular convex polytope. == Visualizing the 120-cell == {| class="wikitable floatright" width="400" |style="vertical-align:top"|[[File:120-cell.gif|200px]]<br>Orthographic projection of the 600-point 120-cell <small><math>\{5,3,3\}</math></small> performing a [[W:SO(4)#Geometry of 4D rotations|simple rotation]].{{Sfn|Hise|2011|loc=File:120-cell.gif|ps=; "Created by Jason Hise with Maya and Macromedia Fireworks.

Therefore even though it is translucent, only its outer surface is visible. The complex interior parts of the 120-cell, all its inscribed 5-cells, 16-cells, 8-cells, 24-cells, 600-cells and its much larger inventory of polyhedra, are completely invisible in this view, as none of their edges are rendered at all. |style="vertical-align:top"|[[File:Ortho solid 016-uniform polychoron p33-t0.png|200px]]<br>Orthographic projection of the 600-point [[W:Great grand stellated 120-cell|great grand stellated 120-cell]] <small><math>\{\tfrac{5}{2},3,3\}</math></small>.{{Sfn|Ruen: Great grand stellated 120-cell|2007}} The 120-cell is its convex hull.

The 120-cell is the convex hull of a regular [[120-cell#Relationships among interior polytopes|compound of each of the 6 regular convex 4-polytopes]]. They are the [[5-cell|5-point (5-cell) 4-simplex]], the [[16-cell|8-point (16-cell) 4-orthoplex]], the [[W:Tesseract|16-point (8-cell) tesseract]], the [[24-cell|24-point (24-cell)]], the [[600-cell|120-point (600-cell)]], and the [[120-cell|600-point (120-cell)]]. The 120-cell is the convex hull of a compound of 120 disjoint regular 5-cells, of 75 disjoint 16-cells, of 25 disjoint 24-cells, and of 5 disjoint 600-cells. The 120-cell contains an even larger inventory of irregular polytopes, created by the intersection of multiple instances of these component regular 4-polytopes. Many are quite unexpected, because they do not occur as components of any regular polytope smaller than the 120-cell. As just one example among the [[120-cell#Concentric hulls|sections of the 120-cell]], there is an irregular 24-point polyhedron with 16 triangle faces and 4 nonagon {9} faces.{{Sfn|Moxness|}} Most renderings of the 120-cell, like the rotating projection here, only illustrate its outer surface, which is a honeycomb of face-bonded dodecahedral cells. Only the objects in its 3-dimensional surface are rendered, namely the 120 dodecahedra, their pentagon faces, and their edges. Although the 120-cell has chords of 30 distinct lengths, in this kind of simplified rendering only the 120-cell's own edges (its shortest chord) are shown. Its 29 interior chords, the edges of objects in the interior of the 120-cell, are not rendered, so interior objects are not visible at all. Visualizing the complete interior of the 600-vertex 120-cell in a single image is impractical because of its complexity. Only four 120-cell edges are incident at each vertex, but [[120-cell#Chords|600 chords (of all 30 lengths)]] are incident at ''each'' vertex. == Compounds in the 120-cell == The 8-point (16-cell), not the 5-point (5-cell), is the smallest building block; it compounds to every larger regular 4-polytope. The 5-point (5-cell) does compound to the 600-point (120-cell), but it does not fit into any smaller regular 4-polytope. The 8-point (16-cell) compounds by 2 in the 16-point (8-cell), and by 3 in the 24-point (24-cell). The 16-point (8-cell) compounds in the 24-point (24-cell) by 3 non-disjoint instances of itself, with each of the 24 vertices shared by two 16-point (8-cells). The 24-point (24-cell) compounds by 5 disjoint instances of itself in the 120-point (600-cell), and the 120-point (600-cell) compounds by 5 disjoint instances of itself in the 600-point (120-cell). The 24-point (24-cell) also compounds by <math>5^2</math> non-disjoint instances of itself in the 120-point (600-cell); it compounds in 5 disjoint instances of itself, 10 (not 5) different ways. Whichever set of 5 disjoint 24-point (24-cells) are assembled, the resulting 120-point (600-cell) contains 25 distinct 24-point (24-cells), not just 5 (or 10). This implies that 15 disjoint 8-point (16-cells) will construct a 120-point (600-cell), which will contain 75 distinct 8-point (16-cells). The 600-point (120-cell) is 5 disjoint 120-point (600-cells), just 2 different ways (not 5 or 10 ways), so it is 10 distinct 120-point (600-cells). This implies that the 8-point (16-cell) compounds by 3 times <math>5^2</math> (75) disjoint instances of itself in the 600-point (120-cell), which contains <math>3^2</math> times <math>5^2</math> (225) distinct instances of the 24-point (24-cell), and <math>3^3</math> times <math>5^2</math> (675) distinct instances of the 8-point (16-cell). These facts were discovered painstakingly by various researchers, and no one has found a general rule governing subsumption relations among regular polytopes. The reasons for some of their numeric incidence relations are far from obvious. [[W:Pieter Hendrik Schoute|Schoute]] was the first to see that the 120-point (600-cell) is a compound of 5 24-point (24-cells) ''10 different ways'', and after he saw it a hundred years lapsed until Denney, Hooker, Johnson, Robinson, Butler & Claiborne proved his result, and showed why.{{Sfn|Denney, Hooker, Johnson, Robinson, Butler & Claiborne|2020|loc=''The geometry of H4 polytopes''}} So much for the compounds of 16-cells. The 120-cell is also the convex hull of the compound of 120 disjoint regular 5-cells. That stellated compound (without its convex hull of 120-cell edges) is the [[w:Great_grand_stellated_120-cell|great grand stellated 120-cell]] illustrated above, the final regular [[W:Stellation|stellation]] of the 120-cell, and the only [[W:Schläfli-Hess polychoron|regular star 4-polytope]] to have the 120-cell for its convex hull. The edges of the great grand stellated 120-cell are <math>\phi^6</math> as long as those of its 120-cell [[W:List of polyhedral stellations#Stellation process|stellation core]] deep inside. The compound of 120 disjoint 5-point (5-cells) can be seen to be equivalent to the compound of 5 disjoint 120-point (600-cells), as follows. Beginning with a single 120-point (600-cell), expand each vertex into a regular 5-cell, by adding 4 new equidistant vertices, such that the 5 vertices form a regular 5-cell inscribed in the 3-sphere. The 120 5-cells are disjoint, and the 600 vertices form 5 disjoint 120-point (600-cells): a 120-cell. == Thirty distinguished distances == The 30 numbers listed in the table are all-important in Euclidean geometry. A case can be made on symmetry grounds that their squares are the 30 most important numbers between 0 and 4. The 30 rows of the table are the 30 distinct [[120-cell#Geodesic rectangles|chord lengths of the unit-radius 120-cell]], the largest regular convex 4-polytope. Since the 120-cell subsumes all smaller regular polytopes, its 30 chords are the complete chord set of all the regular polytopes that can be constructed in the first four dimensions of Euclidean space, except for regular polygons of more than 15 sides. {| class="wikitable" style="white-space:nowrap;text-align:center" !rowspan=2|<math>c_t</math> !rowspan=2|arc

regular polytopes == In 2-space we have the regular 8-point octagon, in 3-space the regular 8-point cube, and in 4-space the regular 8-point [[16-cell]]. A planar octagon with rigid edges of unit length has chords of length: :<math>r_1=1,r_2=\sqrt{2+\sqrt{2}} \approx 1.84776,r_3=1+\sqrt{2} \approx 2.41421,r_4=\sqrt{4 + \sqrt{8}} \approx 2.61313</math> The chord ratio <math>r_3=1+\sqrt{2}</math> is a geometrical proportion, the [[W:Silver ratio|silver ratio]]. Fontaine and Hurley's procedure for obtaining the reciprocal of a chord tells us that: :<math>r_3-r_1-r_1=1/r_3 \approx 0.41421</math> Note that <math>1/r_3=\sqrt{2}-1=r_3-2</math>. If we embed this planar octagon in 3-space, we can make it skew, repositioning its vertices so that each is one unit-edge length distant from three others instead of two others, at the vertices of a unit-edge cube with chords of length: :<math>r_1=1, r_2=\sqrt{2}, r_3=\sqrt{3}, r_4=\sqrt{2}</math> If we embed this cube in 4-space, we can skew it some more, repositioning its vertices so that each is one unit-edge length distant from six others instead of three others, at the vertices of a unit-edge 4-polytope with chords of length: :<math>r_1=1,r_2=1,r_3=1,r_4=\sqrt{2}</math> All of its chords except its long diameters are the same unit length as its edge. In fact they are its 24 edges, and it is a 16-cell of radius <small><math>1/\sqrt{2}</math></small>. [[File:octagon16cell.png|thumb|Orthogonal projection of a regular 16-cell to the [[16-cell#Projections|B<sub>4</sub> Coxeter plane]]. Only its edges are shown; its long diameter chords are not drawn. All 24 edges are the same length. Only the edges of the two disjoint squares lie parallel to the projection plane, in completely orthogonal central planes.]] The [[16-cell]] is the [[W:Regular convex 4-polytope|regular convex 4-polytope]] with [[W:Schläfli symbol|Schläfli symbol]] {3,3,4}. It has 8 vertices, 24 edges, 32 equilateral triangle faces, and 16 regular tetrahedron cells. It is the [[16-cell#Octahedral dipyramid|four-dimensional analogue of the octahedron]], and each of its four orthogonal central hyperplanes is an octahedron. The only planar regular polygons found in the 16-cell are face triangles and central plane squares, but the 16-cell also contains a skew regular octagon, its [[W:Petrie polygon|Petrie polygon]]. The chords of this regular octagon, which lies skew in 4-space, are those given above for the 16-cell, as opposed to those for the cube or the regular octagon in the plane. The 16-cell is a construct of 3 Petrie octagons which share the same 8 vertices but have disjoint sets of 8 edges each. The regular octad has higher symmetry in 4-space than it does in 2-space. The 16-cell is the 4-orthoplex, the simplest regular 4-polytope after the [[5-cell|4-simplex]]. All the larger regular 4-polytopes, including the 120-cell, are compounds of the 16-cell. The regular octagon exhibits this high symmetry only when embedded in 4-space at the vertices of the 16-cell. The 16-cell constitutes an [[W:Orthonormal basis|orthonormal basis]] for the choice of a 4-dimensional Cartesian reference frame, because its vertices define four orthogonal axes. The eight vertices of a unit-radius 16-cell are (±1, 0, 0, 0), (0, ±1, 0, 0), (0, 0, ±1, 0), (0, 0, 0, ±1). All vertices are connected by <small><math>\sqrt{2}</math></small> edges except opposite pairs. The vertex coordinates of the 16-cell form 6 central squares lying in 6 pairwise [[W:Orthogonal|orthogonal]] coordinate planes. Great squares in ''opposite'' planes that do not share an axis (e.g. in the ''xy'' and ''wz'' planes) are completely disjoint (they do not intersect at any vertices). These planes are [[W:Completely orthogonal|completely orthogonal]].{{Efn|name=Six orthogonal planes of the Cartesian basis}} Since this unit-radius coordinate system is convenient, let us derive the unit-radius 16-cell by skewing a unit-radius planar octagon, which has chords of length: :<math>r_1=\sqrt{2-\sqrt{2}} \approx 0.76537,r_2=\sqrt{2},r_3=\sqrt{2+\sqrt{2}} \approx 1.84776,r_4=2</math> We will need a planar octagon with rigid <math>r_2</math> chords, rather than one with rigid <math>r_1</math> edges. The octagon's <math>r_2</math> chords form two disjoint great squares, visible in the orthogonal projection, which we can reposition in 3-space to form a cube by making them parallel, and in 4-space to form a 16-cell by making them completely orthogonal. In the 16-cell the two disjoint great squares formed by the <math>r_2</math> chords are both parallel and perpendicular to each other. A ''simple'' rotation of the 16-cell in ''one'' of those two central planes rotates that square like a wheel, while the other square does not move. The four vertices of the rotating square orbit on a great circle. The <math>r_1</math> chords of the 16-cell form a Petrie polygon which zig-zags back and forth between the two completely orthogonal <math>r_2</math> squares. The <math>r_3</math> chords of the 16-cell form a circular helix, visible as a skew {8/3} polygram in the orthogonal projection. A ''double'' rotation of the 16-cell, in ''both'' of the two completely orthogonal <math>r_2</math> central square planes at once, moves the vertices along the circular helix over the <math>r_3</math> chords. [[W:Rotations in 4-dimensional Euclidean space|Rotations in 4-dimensional Euclidean space]] can be seen as the composition of two 2-dimensional rotations in completely orthogonal planes. The general rotation in 4-space is a double rotation in pairs of completely orthogonal planes. Two completely orthogonal planes are called invariant planes of the rotation when all points in the plane rotate on circles that remain in the plane, even as the whole plane tilts sideways (like a coin flipping) into another plane. The two completely orthogonal rotations of each plane (like a wheel, and like a coin flipping) are simultaneous but independent, in that they are not geometrically constrained to turn at the same rate. However, the most circular kind of rotation (as opposed to an elliptical double rotation of a rigid spherical object) occurs when the invariant planes do rotate through the same angle in the same time interval. Such equi-angled double rotations are called [[w:SO(4)#Isoclinic_rotations|isoclinic]], also [[w:William_Kingdon_Clifford|Clifford]] displacements. The 16-cell is the simplest possible frame in which to [[16-cell#Rotations|observe 4-dimensional rotations]] because its characteristic isoclinic rotations feature a single pair of invariant rotation planes. In the 16-cell an isoclinic rotation by 90° in any pair of invariant completely orthogonal square central planes takes every square central plane to its completely orthogonal square central plane in a twisting displacment, as they tilt sideways 90° into each other's plane while rotating 90° internally. All the vertices move at once on separate circular [[w:Geodesic|geodesics]], displaced 90° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. When the 90° isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 90°, but from the new orientation in a direction orthogonal to its first 90° displacement. After 360° of rotation each vertex reaches its antipodal position. The trajectory of each vertex over each 90° isoclinic rotational displacement is a one-eighth segment of its geodesic orbit. Its entire orbit traces a circular helix in 4-space over eight <math>r_3</math> chords, and also traces a great circle twice over the four <math>r_2</math> chords of one of the two moving invariant rotation planes. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once and returns to its original position, and the 16-cell returns to its original orientation. == Hypercubes == The long diameter of the unit-edge [[W:Hypercube|hypercube]] of dimension <small><math>n</math></small> is <small><math>\sqrt{n}</math></small>, so the unit-edge [[w:Tesseract|4-hypercube, the 16-point (8-cell) tesseract,]] has chords: :<math>r_1=\sqrt{1},r_2=\sqrt{2},r_3=\sqrt{3},r_4=\sqrt{4}</math> Uniquely in its 4-dimensional case, the hypercube's edge length equals its radius, like the hexagon. We call such polytopes ''radially equilateral'', because they can be constructed from equilateral triangles which meet at their center, each contributing two radii and an edge. The cuboctahedron and the 24-cell are also radially equilateral. The [[W:Tesseract|tesseract]] is the [[W:Regular convex 4-polytope|regular convex 4-polytope]] with [[W:Schläfli symbol|Schläfli symbol]] {4,3,3}. It has 16 vertices, 32 edges, 24 square faces, and 8 cube cells. It is the four-dimensional analogue of the cube. The tesseract is the [[W:Dual polytope|dual polytope]] of the 16-cell. They have the same Petrie polygon, the regular octagon, but the tesseract contains 2 disjoint instances and 4 distinct instances of the skew octagon. We can construct the tesseract by skewing two planar octagons. Because the tesseract is radially equilateral (unlike the 16-cell), we start with our original octagon of unit-edge length, rather than the octagon of edge length <small><math>\sqrt{2}</math></small> that we needed to build the unit-radius 16-cell. For our tesseract construction we skew each planar octagon into a cube, so we have a compound of two completely orthogonal cubes. Provided the planes were completely orthogonal in 4-space and we skewed them both the same way, the 16 vertices will be the vertices of a tesseract with half of its 32 edges missing. The 16-point tesseract is the convex hull of a compound of two 8-point 16-cells, in exact dimensional analogy to the way the 8-point cube is the convex hull of a [[W:Stellated octahedron|compound of two regular 4-point tetrahedra]]. The [[W:Demihypercube|demihypercubes]] occupy alternate vertices of the hypercubes. The diagonals of the square faces of the unit-radius tesseract are the <small><math>\sqrt{2}</math></small> edges of two unit-radius 16-cells, which are also the edges of the square central planes. Because the tesseract contains two 16-cells in alternate positions it has two sets of 6 orthogonal square central planes. Two angles are required to specify the relationship between two planes in 4-space. Pairs of planes within each 16-cell are 90° apart in one angle, and either 0° or 90° apart in the other angle. They are 90° apart in both angles if and only if they are completely orthogonal planes, 90° apart by isoclinic rotation, with no vertices in common and their corresponding vertices 180° apart. Otherwise they are 0° apart in one of the angles, 90° apart by simple rotation with their corresponding vertices 90° apart, and they intersect in one axis and lie in a common 3-dimensional hyperplane.{{Efn|A double rotation in which one of the two angles of rotation is 0°, so that one of the completely orthogonal invariant planes does not rotate, is called a simple rotation. Ordinary rotations observed in a 3-dimensional space are simple rotations.}} A pair of square central planes from alternate 16-cells are 60° apart by isoclinic rotation, with their corresponding vertices 120° apart. The planes are not orthogonal or parallel, so they intersect in a line somewhere, but they have no vertices in common, they have no 3-dimensional hyperplane in common, and they cannot reach each other by simple rotation. Such pairs of objects are called [[W:Clifford parallel|Clifford parallel]] because all their corresponding pairs of vertices are the same distance apart, although they are not parallel in the usual sense, because they have a common center. Not only the alternate 16-cells' corresponding square central planes, but also the 16-cells themselves, are Clifford parallel objects. We can rotate the tesseract isoclinically the way we rotated the 16-cell, by 90° in two completely orthogonal invariant square central planes, with the same effect on both alternate 16-cells. In the course of a 720° isoclinic rotation in invariant square central planes each vertex departs from all 8 vertex positions of its 16-cell just once and returns to its original position, but it does not visit the vertex positions of the other 16-cell. The skew octagon geodesic orbits of the 16 vertices are disjoint circular helixes, and those 16 circular helixes are Clifford parallel objects. == The 24-cell == In 2-space we have the radially equilateral 6-point hexagon. In 3-space we have the radially equilateral 12-point cuboctahedron, with 4 hexagonal central planes. In 4-space we have the radially equilateral 24-point 24-cell, with 4 cuboctahedral central hyperplanes and 16 hexagonal central planes. Great hexagons are a rounder choice than great squares for the invariant rotation planes in which to rotate a 4-polytope isoclinically. The complete hexagonal isoclinic revolution requires 720° like the square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 90° each. ... == The 600-cell == ... == Finally the 120-cell == ... == Conclusions == Fontaine and Hurley's discovery is more than a formula for the reciprocal of a regular ''n''-polygon diagonal. It also yields the discrete sequence of isocline chords of the distinct isoclinic rotation characteristic of a ''d''-dimensional regular polytope. The characteristic rotational chord sequence of the ''d''-polytope can be represented geometrically in two dimensions on a distinct star polygon, but it lies on a geodesic circle through ''d''-dimensional space. Fontaine and Hurley discovered the geodesic topology of polytopes generally. Their procedure will reveal the geodesics of arbitrary non-uniform polytopes, since it can be applied to a polytope of any dimensionality and irregularity, by first fitting the polytope to the smallest regular polygon whose chords include its chords. Fontaine and Hurley's discovery of a chordal formula for isoclinic rotations closes the circuit on Kappraff and Adamson's discovery of a rotational connection between dynamical systems, Steinbach's golden fields, and Coxeter's Euclidean geometry of ''n'' dimensions. Application of the Fontaine and Hurley procedure in higher-dimensional spaces demonstrates why the connection exists: because polytope sequences generally, from Steinbach's golden polygon chord sequences, to chord sequences in isoclinic rotation helixes, to subsumption relations in the sequence of regular 4-polytopes, arise as expressions of the reflections and rotations of distinct Coxeter symmetry groups, when those various groups interact. == Appendix: Sequence of regular 4-polytopes == {{Regular convex 4-polytopes|wiki=W:|columns=7}} == Notes == {{Notelist}} == Citations == {{Reflist}} == References == {{Refbegin}} * {{Cite journal | last=Steinbach | first=Peter | year=1997 | title=Golden fields: A case for the Heptagon | journal=Mathematics Magazine | volume=70 | issue=Feb 1997 | pages=22–31 | doi=10.1080/0025570X.1997.11996494 | jstor=2691048 | ref={{SfnRef|Steinbach|1997}} }} * {{Cite journal | last=Steinbach | first=Peter | year=2000 | title=Sections Beyond Golden| journal=Bridges: Mathematical Connections in Art, Music and Science | issue=2000 | pages=35-44 | url=https://archive.bridgesmathart.org/2000/bridges2000-35.pdf | ref={{SfnRef|Steinbach|2000}}}} * {{Cite journal | last1=Kappraff | first1=Jay | last2=Jablan | first2=Slavik | last3=Adamson | first3=Gary | last4=Sazdanovich | first4=Radmila | year=2004 | title=Golden Fields, Generalized Fibonacci Sequences, and Chaotic Matrices | journal=Forma | volume=19 | pages=367-387 | url=https://archive.bridgesmathart.org/2005/bridges2005-369.pdf | ref={{SfnRef|Kappraff, Jablan, Adamson & Sazdanovich|2004}} }} * {{Cite journal | last1=Kappraff | first1=Jay | last2=Adamson | first2=Gary | year=2004 | title=Polygons and Chaos | journal=Dynamical Systems and Geometric Theories | url=https://archive.bridgesmathart.org/2001/bridges2001-67.pdf | ref={{SfnRef|Kappraff & Adamson|2004}} }} * {{Cite journal | last1=Fontaine | first1=Anne | last2=Hurley | first2=Susan | year=2006 | title=Proof by Picture: Products and Reciprocals of Diagonal Length Ratios in the Regular Polygon | journal=Forum Geometricorum | volume=6 | pages=97-101 | url=https://scispace.com/pdf/proof-by-picture-products-and-reciprocals-of-diagonal-length-1aian8mgp9.pdf }} {{Refend}} 80q5ea0sd4ih9pvkrz2ayjmupl5r8cw 2809787 2809780 2026-05-17T01:04:10Z Dc.samizdat 2856930 /* The 8-point regular polytopes */ 2809787 wikitext text/x-wiki {{align|center|David Brooks Christie}} {{align|center|dc@samizdat.org}} {{align|center|Draft in progress}} {{align|center|January 2026 - April 2026}} <blockquote>Steinbach discovered the formula for the ratios of diagonal to side in the regular polygons. Fontaine and Hurley extended this result, discovering a formula for the reciprocal of a regular polygon chord derived geometrically from the chord's star polygon. We observe that these findings in plane geometry apply more generally, to polytopes of any dimensionality. Fontaine and Hurley's geometric procedure for finding the reciprocals of the chords of a regular polygon from their star polygons also finds the rotational geodesics of any polytope of any dimensionality.</blockquote> == Introduction == Steinbach discovered the Diagonal Product Formula and the Golden Fields family of ratios of diagonal to side in the regular polygons. He showed how this family extends beyond the pentagon {5} with its well-known golden bisection proportional to 𝜙, finding that the heptagon {7} has an analogous trisection, the nonagon {9} has an analogous quadrasection, and the hendecagon {11} has an analogous pentasection, an extended family of golden proportions with quasiperiodic properties. Kappraff and Adamson extended these findings in plane geometry to a theory of Generalized Fibonacci Sequences, showing that the Golden Fields not only do not end with the hendecagon, they form an infinite number of periodic trajectories when operated on by the Mandelbrot operator. They found a relation between the edges of star polygons and dynamical systems in the state of chaos, revealing a connection between chaos theory, number, and rotations in Coxeter Euclidean geometry. Fontaine and Hurley examined Steinbach's finding that the length of each chord of a regular polygon is both the product of two chords and the sum of a set of smaller chords, so that in rotations to add is to multiply. They illustrated Steinbach's sets of additive chords lying parallel to each other in the plane (pointing in the same direction), and by applying Steinbach's formula more generally they found another summation relation of signed parallel chords (pointing in opposite directions) which relates each chord length to its reciprocal, and relates the summation to a distinct star polygon rotation. We examine these remarkable findings (which stem from study of the chords of humble regular polygons) in higher-dimensional spaces, specifically in the chords, polygons and rotations of the [[120-cell]], the largest four-dimensional regular convex polytope. == Visualizing the 120-cell == {| class="wikitable floatright" width="400" |style="vertical-align:top"|[[File:120-cell.gif|200px]]<br>Orthographic projection of the 600-point 120-cell <small><math>\{5,3,3\}</math></small> performing a [[W:SO(4)#Geometry of 4D rotations|simple rotation]].{{Sfn|Hise|2011|loc=File:120-cell.gif|ps=; "Created by Jason Hise with Maya and Macromedia Fireworks.

Therefore even though it is translucent, only its outer surface is visible. The complex interior parts of the 120-cell, all its inscribed 5-cells, 16-cells, 8-cells, 24-cells, 600-cells and its much larger inventory of polyhedra, are completely invisible in this view, as none of their edges are rendered at all. |style="vertical-align:top"|[[File:Ortho solid 016-uniform polychoron p33-t0.png|200px]]<br>Orthographic projection of the 600-point [[W:Great grand stellated 120-cell|great grand stellated 120-cell]] <small><math>\{\tfrac{5}{2},3,3\}</math></small>.{{Sfn|Ruen: Great grand stellated 120-cell|2007}} The 120-cell is its convex hull.

The 120-cell is the convex hull of a regular [[120-cell#Relationships among interior polytopes|compound of each of the 6 regular convex 4-polytopes]]. They are the [[5-cell|5-point (5-cell) 4-simplex]], the [[16-cell|8-point (16-cell) 4-orthoplex]], the [[W:Tesseract|16-point (8-cell) tesseract]], the [[24-cell|24-point (24-cell)]], the [[600-cell|120-point (600-cell)]], and the [[120-cell|600-point (120-cell)]]. The 120-cell is the convex hull of a compound of 120 disjoint regular 5-cells, of 75 disjoint 16-cells, of 25 disjoint 24-cells, and of 5 disjoint 600-cells. The 120-cell contains an even larger inventory of irregular polytopes, created by the intersection of multiple instances of these component regular 4-polytopes. Many are quite unexpected, because they do not occur as components of any regular polytope smaller than the 120-cell. As just one example among the [[120-cell#Concentric hulls|sections of the 120-cell]], there is an irregular 24-point polyhedron with 16 triangle faces and 4 nonagon {9} faces.{{Sfn|Moxness|}} Most renderings of the 120-cell, like the rotating projection here, only illustrate its outer surface, which is a honeycomb of face-bonded dodecahedral cells. Only the objects in its 3-dimensional surface are rendered, namely the 120 dodecahedra, their pentagon faces, and their edges. Although the 120-cell has chords of 30 distinct lengths, in this kind of simplified rendering only the 120-cell's own edges (its shortest chord) are shown. Its 29 interior chords, the edges of objects in the interior of the 120-cell, are not rendered, so interior objects are not visible at all. Visualizing the complete interior of the 600-vertex 120-cell in a single image is impractical because of its complexity. Only four 120-cell edges are incident at each vertex, but [[120-cell#Chords|600 chords (of all 30 lengths)]] are incident at ''each'' vertex. == Compounds in the 120-cell == The 8-point (16-cell), not the 5-point (5-cell), is the smallest building block; it compounds to every larger regular 4-polytope. The 5-point (5-cell) does compound to the 600-point (120-cell), but it does not fit into any smaller regular 4-polytope. The 8-point (16-cell) compounds by 2 in the 16-point (8-cell), and by 3 in the 24-point (24-cell). The 16-point (8-cell) compounds in the 24-point (24-cell) by 3 non-disjoint instances of itself, with each of the 24 vertices shared by two 16-point (8-cells). The 24-point (24-cell) compounds by 5 disjoint instances of itself in the 120-point (600-cell), and the 120-point (600-cell) compounds by 5 disjoint instances of itself in the 600-point (120-cell). The 24-point (24-cell) also compounds by <math>5^2</math> non-disjoint instances of itself in the 120-point (600-cell); it compounds in 5 disjoint instances of itself, 10 (not 5) different ways. Whichever set of 5 disjoint 24-point (24-cells) are assembled, the resulting 120-point (600-cell) contains 25 distinct 24-point (24-cells), not just 5 (or 10). This implies that 15 disjoint 8-point (16-cells) will construct a 120-point (600-cell), which will contain 75 distinct 8-point (16-cells). The 600-point (120-cell) is 5 disjoint 120-point (600-cells), just 2 different ways (not 5 or 10 ways), so it is 10 distinct 120-point (600-cells). This implies that the 8-point (16-cell) compounds by 3 times <math>5^2</math> (75) disjoint instances of itself in the 600-point (120-cell), which contains <math>3^2</math> times <math>5^2</math> (225) distinct instances of the 24-point (24-cell), and <math>3^3</math> times <math>5^2</math> (675) distinct instances of the 8-point (16-cell). These facts were discovered painstakingly by various researchers, and no one has found a general rule governing subsumption relations among regular polytopes. The reasons for some of their numeric incidence relations are far from obvious. [[W:Pieter Hendrik Schoute|Schoute]] was the first to see that the 120-point (600-cell) is a compound of 5 24-point (24-cells) ''10 different ways'', and after he saw it a hundred years lapsed until Denney, Hooker, Johnson, Robinson, Butler & Claiborne proved his result, and showed why.{{Sfn|Denney, Hooker, Johnson, Robinson, Butler & Claiborne|2020|loc=''The geometry of H4 polytopes''}} So much for the compounds of 16-cells. The 120-cell is also the convex hull of the compound of 120 disjoint regular 5-cells. That stellated compound (without its convex hull of 120-cell edges) is the [[w:Great_grand_stellated_120-cell|great grand stellated 120-cell]] illustrated above, the final regular [[W:Stellation|stellation]] of the 120-cell, and the only [[W:Schläfli-Hess polychoron|regular star 4-polytope]] to have the 120-cell for its convex hull. The edges of the great grand stellated 120-cell are <math>\phi^6</math> as long as those of its 120-cell [[W:List of polyhedral stellations#Stellation process|stellation core]] deep inside. The compound of 120 disjoint 5-point (5-cells) can be seen to be equivalent to the compound of 5 disjoint 120-point (600-cells), as follows. Beginning with a single 120-point (600-cell), expand each vertex into a regular 5-cell, by adding 4 new equidistant vertices, such that the 5 vertices form a regular 5-cell inscribed in the 3-sphere. The 120 5-cells are disjoint, and the 600 vertices form 5 disjoint 120-point (600-cells): a 120-cell. == Thirty distinguished distances == The 30 numbers listed in the table are all-important in Euclidean geometry. A case can be made on symmetry grounds that their squares are the 30 most important numbers between 0 and 4. The 30 rows of the table are the 30 distinct [[120-cell#Geodesic rectangles|chord lengths of the unit-radius 120-cell]], the largest regular convex 4-polytope. Since the 120-cell subsumes all smaller regular polytopes, its 30 chords are the complete chord set of all the regular polytopes that can be constructed in the first four dimensions of Euclidean space, except for regular polygons of more than 15 sides. {| class="wikitable" style="white-space:nowrap;text-align:center" !rowspan=2|<math>c_t</math> !rowspan=2|arc

regular polytopes == In 2-space we have the regular 8-point octagon, in 3-space the regular 8-point cube, and in 4-space the regular 8-point [[16-cell]]. A planar octagon with rigid edges of unit length has chords of length: :<math>r_1=1,r_2=\sqrt{2+\sqrt{2}} \approx 1.84776,r_3=1+\sqrt{2} \approx 2.41421,r_4=\sqrt{4 + \sqrt{8}} \approx 2.61313</math> The chord ratio <math>r_3=1+\sqrt{2}</math> is a geometrical proportion, the [[W:Silver ratio|silver ratio]]. Fontaine and Hurley's procedure for obtaining the reciprocal of a chord tells us that: :<math>r_3-r_1-r_1=1/r_3 \approx 0.41421</math> Note that <math>1/r_3=\sqrt{2}-1=r_3-2</math>. If we embed this planar octagon in 3-space, we can make it skew, repositioning its vertices so that each is one unit-edge length distant from three others instead of two others, at the vertices of a unit-edge cube with chords of length: :<math>r_1=1, r_2=\sqrt{2}, r_3=\sqrt{3}, r_4=\sqrt{2}</math> If we embed this cube in 4-space, we can skew it some more, repositioning its vertices so that each is one unit-edge length distant from six others instead of three others, at the vertices of a unit-edge 4-polytope with chords of length: :<math>r_1=1,r_2=1,r_3=1,r_4=\sqrt{2}</math> All of its chords except its long diameters are the same unit length as its edge. In fact they are its 24 edges, and it is a 16-cell of radius <small><math>1/\sqrt{2}</math></small>. [[File:octagon16cell.png|thumb|Orthogonal projection of a regular 16-cell to the [[16-cell#Projections|B<sub>4</sub> Coxeter plane]]. Only its edges are shown; its long diameter chords are not drawn. All 24 edges are the same length. Only the edges of the two disjoint squares lie parallel to the projection plane, in completely orthogonal central planes.]] The [[16-cell]] is the [[W:Regular convex 4-polytope|regular convex 4-polytope]] with [[W:Schläfli symbol|Schläfli symbol]] {3,3,4}. It has 8 vertices, 24 edges, 32 equilateral triangle faces, and 16 regular tetrahedron cells. It is the [[16-cell#Octahedral dipyramid|four-dimensional analogue of the octahedron]], and each of its four orthogonal central hyperplanes is an octahedron. The only planar regular polygons found in the 16-cell are face triangles and central plane squares, but the 16-cell also contains a skew regular octagon, its [[W:Petrie polygon|Petrie polygon]]. The chords of this regular octagon, which lies skew in 4-space, are those given above for the 16-cell, as opposed to those for the cube or the regular octagon in the plane. The 16-cell is a construct of 3 Petrie octagons which share the same 8 vertices but have disjoint sets of 8 edges each. The regular octad has higher symmetry in 4-space than it does in 2-space. The 16-cell is the 4-orthoplex, the simplest regular 4-polytope after the [[5-cell|4-simplex]]. All the larger regular 4-polytopes, including the 120-cell, are compounds of the 16-cell. The regular octagon exhibits this high symmetry only when embedded in 4-space at the vertices of the 16-cell. The 16-cell constitutes an [[W:Orthonormal basis|orthonormal basis]] for the choice of a 4-dimensional Cartesian reference frame, because its vertices define four orthogonal axes. The eight vertices of a unit-radius 16-cell are (±1, 0, 0, 0), (0, ±1, 0, 0), (0, 0, ±1, 0), (0, 0, 0, ±1). All vertices are connected by <small><math>\sqrt{2}</math></small> edges except opposite pairs. The vertex coordinates of the 16-cell form 6 central squares lying in 6 pairwise [[W:Orthogonal|orthogonal]] coordinate planes. Great squares in ''opposite'' planes that do not share an axis (e.g. in the ''xy'' and ''wz'' planes) are completely disjoint (they do not intersect at any vertices). These planes are [[W:Completely orthogonal|completely orthogonal]].{{Efn|name=Six orthogonal planes of the Cartesian basis}} Since this unit-radius coordinate system is convenient, let us derive the unit-radius 16-cell by skewing a unit-radius planar octagon, which has chords of length: :<math>r_1=\sqrt{2-\sqrt{2}} \approx 0.76537,r_2=\sqrt{2},r_3=\sqrt{2+\sqrt{2}} \approx 1.84776,r_4=2</math> We will need a planar octagon with rigid <math>r_2</math> chords, rather than one with rigid <math>r_1</math> edges. The octagon's <math>r_2</math> chords form two disjoint great squares, visible in the orthogonal projection, which we can reposition in 3-space to form a cube by making them parallel, and in 4-space to form a 16-cell by making them completely orthogonal. In the 16-cell the two disjoint great squares formed by the <math>r_2</math> chords are both parallel and perpendicular to each other. A ''simple'' rotation of the 16-cell in ''one'' of those two central planes rotates that square like a wheel, while the other square does not move. The four vertices of the rotating square orbit on a great circle. The <math>r_1</math> chords of the 16-cell form a Petrie polygon which zig-zags back and forth between the two completely orthogonal <math>r_2</math> squares. The <math>r_3</math> chords of the 16-cell form a circular helix, visible as a skew {8/3} polygram in the orthogonal projection. A ''double'' rotation of the 16-cell, in ''both'' of the two completely orthogonal <math>r_2</math> central square planes at once, moves the eight vertices along the circular helix over the <math>r_3</math> chords. [[W:Rotations in 4-dimensional Euclidean space|Rotations in 4-dimensional Euclidean space]] can be seen as the composition of two 2-dimensional rotations in completely orthogonal planes. The general rotation in 4-space is a double rotation in pairs of completely orthogonal planes. Two completely orthogonal planes are called invariant planes of the rotation when all points in the plane rotate on circles that remain in the plane, even as the whole plane tilts sideways (like a coin flipping) into another plane. The two completely orthogonal rotations of each plane (like a wheel, and like a coin flipping) are simultaneous but independent, in that they are not geometrically constrained to turn at the same rate. However, the most circular kind of rotation (as opposed to an elliptical double rotation of a rigid spherical object) occurs when the invariant planes do rotate through the same angle in the same time interval. Such equi-angled double rotations are called [[w:SO(4)#Isoclinic_rotations|isoclinic]], also [[w:William_Kingdon_Clifford|Clifford]] displacements. The 16-cell is the simplest possible frame in which to [[16-cell#Rotations|observe 4-dimensional rotations]] because its characteristic isoclinic rotations feature a single pair of invariant rotation planes. In the 16-cell an isoclinic rotation by 90° in any pair of invariant completely orthogonal square central planes takes every square central plane to its completely orthogonal square central plane in a twisting displacment, as they tilt sideways 90° into each other's plane while rotating 90° internally. All the vertices move at once on separate circular [[w:Geodesic|geodesics]], displaced 90° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. When the 90° isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 90°, but from the new orientation in a direction orthogonal to its first 90° displacement. After 360° of rotation each vertex reaches its antipodal position. The trajectory of each vertex over each 90° isoclinic rotational displacement is a one-eighth segment of its geodesic orbit. Its entire orbit traces a circular helix in 4-space over eight <math>r_3</math> chords, and also traces a great circle twice over the four <math>r_2</math> chords of one of the two moving invariant rotation planes. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once and returns to its original position, and the 16-cell returns to its original orientation. == Hypercubes == The long diameter of the unit-edge [[W:Hypercube|hypercube]] of dimension <small><math>n</math></small> is <small><math>\sqrt{n}</math></small>, so the unit-edge [[w:Tesseract|4-hypercube, the 16-point (8-cell) tesseract,]] has chords: :<math>r_1=\sqrt{1},r_2=\sqrt{2},r_3=\sqrt{3},r_4=\sqrt{4}</math> Uniquely in its 4-dimensional case, the hypercube's edge length equals its radius, like the hexagon. We call such polytopes ''radially equilateral'', because they can be constructed from equilateral triangles which meet at their center, each contributing two radii and an edge. The cuboctahedron and the 24-cell are also radially equilateral. The [[W:Tesseract|tesseract]] is the [[W:Regular convex 4-polytope|regular convex 4-polytope]] with [[W:Schläfli symbol|Schläfli symbol]] {4,3,3}. It has 16 vertices, 32 edges, 24 square faces, and 8 cube cells. It is the four-dimensional analogue of the cube. The tesseract is the [[W:Dual polytope|dual polytope]] of the 16-cell. They have the same Petrie polygon, the regular octagon, but the tesseract contains 2 disjoint instances and 4 distinct instances of the skew octagon. We can construct the tesseract by skewing two planar octagons. Because the tesseract is radially equilateral (unlike the 16-cell), we start with our original octagon of unit-edge length, rather than the octagon of edge length <small><math>\sqrt{2}</math></small> that we needed to build the unit-radius 16-cell. For our tesseract construction we skew each planar octagon into a cube, so we have a compound of two completely orthogonal cubes. Provided the planes were completely orthogonal in 4-space and we skewed them both the same way, the 16 vertices will be the vertices of a tesseract with half of its 32 edges missing. The 16-point tesseract is the convex hull of a compound of two 8-point 16-cells, in exact dimensional analogy to the way the 8-point cube is the convex hull of a [[W:Stellated octahedron|compound of two regular 4-point tetrahedra]]. The [[W:Demihypercube|demihypercubes]] occupy alternate vertices of the hypercubes. The diagonals of the square faces of the unit-radius tesseract are the <small><math>\sqrt{2}</math></small> edges of two unit-radius 16-cells, which are also the edges of the square central planes. Because the tesseract contains two 16-cells in alternate positions it has two sets of 6 orthogonal square central planes. Two angles are required to specify the relationship between two planes in 4-space. Pairs of planes within each 16-cell are 90° apart in one angle, and either 0° or 90° apart in the other angle. They are 90° apart in both angles if and only if they are completely orthogonal planes, 90° apart by isoclinic rotation, with no vertices in common and their corresponding vertices 180° apart. Otherwise they are 0° apart in one of the angles, 90° apart by simple rotation with their corresponding vertices 90° apart, and they intersect in one axis and lie in a common 3-dimensional hyperplane.{{Efn|A double rotation in which one of the two angles of rotation is 0°, so that one of the completely orthogonal invariant planes does not rotate, is called a simple rotation. Ordinary rotations observed in a 3-dimensional space are simple rotations.}} A pair of square central planes from alternate 16-cells are 60° apart by isoclinic rotation, with their corresponding vertices 120° apart. The planes are not orthogonal or parallel, so they intersect in a line somewhere, but they have no vertices in common, they have no 3-dimensional hyperplane in common, and they cannot reach each other by simple rotation. Such pairs of objects are called [[W:Clifford parallel|Clifford parallel]] because all their corresponding pairs of vertices are the same distance apart, although they are not parallel in the usual sense, because they have a common center. Not only the alternate 16-cells' corresponding square central planes, but also the 16-cells themselves, are Clifford parallel objects. We can rotate the tesseract isoclinically the way we rotated the 16-cell, by 90° in two completely orthogonal invariant square central planes, with the same effect on both alternate 16-cells. In the course of a 720° isoclinic rotation in invariant square central planes each vertex departs from all 8 vertex positions of its 16-cell just once and returns to its original position, but it does not visit the vertex positions of the other 16-cell. The skew octagon geodesic orbits of the 16 vertices are disjoint circular helixes, and those 16 circular helixes are Clifford parallel objects. == The 24-cell == In 2-space we have the radially equilateral 6-point hexagon. In 3-space we have the radially equilateral 12-point cuboctahedron, with 4 hexagonal central planes. In 4-space we have the radially equilateral 24-point 24-cell, with 4 cuboctahedral central hyperplanes and 16 hexagonal central planes. Great hexagons are a rounder choice than great squares for the invariant rotation planes in which to rotate a 4-polytope isoclinically. The complete hexagonal isoclinic revolution requires 720° like the square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 90° each. ... == The 600-cell == ... == Finally the 120-cell == ... == Conclusions == Fontaine and Hurley's discovery is more than a formula for the reciprocal of a regular ''n''-polygon diagonal. It also yields the discrete sequence of isocline chords of the distinct isoclinic rotation characteristic of a ''d''-dimensional regular polytope. The characteristic rotational chord sequence of the ''d''-polytope can be represented geometrically in two dimensions on a distinct star polygon, but it lies on a geodesic circle through ''d''-dimensional space. Fontaine and Hurley discovered the geodesic topology of polytopes generally. Their procedure will reveal the geodesics of arbitrary non-uniform polytopes, since it can be applied to a polytope of any dimensionality and irregularity, by first fitting the polytope to the smallest regular polygon whose chords include its chords. Fontaine and Hurley's discovery of a chordal formula for isoclinic rotations closes the circuit on Kappraff and Adamson's discovery of a rotational connection between dynamical systems, Steinbach's golden fields, and Coxeter's Euclidean geometry of ''n'' dimensions. Application of the Fontaine and Hurley procedure in higher-dimensional spaces demonstrates why the connection exists: because polytope sequences generally, from Steinbach's golden polygon chord sequences, to chord sequences in isoclinic rotation helixes, to subsumption relations in the sequence of regular 4-polytopes, arise as expressions of the reflections and rotations of distinct Coxeter symmetry groups, when those various groups interact. == Appendix: Sequence of regular 4-polytopes == {{Regular convex 4-polytopes|wiki=W:|columns=7}} == Notes == {{Notelist}} == Citations == {{Reflist}} == References == {{Refbegin}} * {{Cite journal | last=Steinbach | first=Peter | year=1997 | title=Golden fields: A case for the Heptagon | journal=Mathematics Magazine | volume=70 | issue=Feb 1997 | pages=22–31 | doi=10.1080/0025570X.1997.11996494 | jstor=2691048 | ref={{SfnRef|Steinbach|1997}} }} * {{Cite journal | last=Steinbach | first=Peter | year=2000 | title=Sections Beyond Golden| journal=Bridges: Mathematical Connections in Art, Music and Science | issue=2000 | pages=35-44 | url=https://archive.bridgesmathart.org/2000/bridges2000-35.pdf | ref={{SfnRef|Steinbach|2000}}}} * {{Cite journal | last1=Kappraff | first1=Jay | last2=Jablan | first2=Slavik | last3=Adamson | first3=Gary | last4=Sazdanovich | first4=Radmila | year=2004 | title=Golden Fields, Generalized Fibonacci Sequences, and Chaotic Matrices | journal=Forma | volume=19 | pages=367-387 | url=https://archive.bridgesmathart.org/2005/bridges2005-369.pdf | ref={{SfnRef|Kappraff, Jablan, Adamson & Sazdanovich|2004}} }} * {{Cite journal | last1=Kappraff | first1=Jay | last2=Adamson | first2=Gary | year=2004 | title=Polygons and Chaos | journal=Dynamical Systems and Geometric Theories | url=https://archive.bridgesmathart.org/2001/bridges2001-67.pdf | ref={{SfnRef|Kappraff & Adamson|2004}} }} * {{Cite journal | last1=Fontaine | first1=Anne | last2=Hurley | first2=Susan | year=2006 | title=Proof by Picture: Products and Reciprocals of Diagonal Length Ratios in the Regular Polygon | journal=Forum Geometricorum | volume=6 | pages=97-101 | url=https://scispace.com/pdf/proof-by-picture-products-and-reciprocals-of-diagonal-length-1aian8mgp9.pdf }} {{Refend}} 9j9qrghhf9t77f3umvw86apt8j0eqr9 2809824 2809787 2026-05-17T03:19:20Z Dc.samizdat 2856930 /* The 8-point regular polytopes */ 2809824 wikitext text/x-wiki {{align|center|David Brooks Christie}} {{align|center|dc@samizdat.org}} {{align|center|Draft in progress}} {{align|center|January 2026 - April 2026}} <blockquote>Steinbach discovered the formula for the ratios of diagonal to side in the regular polygons. Fontaine and Hurley extended this result, discovering a formula for the reciprocal of a regular polygon chord derived geometrically from the chord's star polygon. We observe that these findings in plane geometry apply more generally, to polytopes of any dimensionality. Fontaine and Hurley's geometric procedure for finding the reciprocals of the chords of a regular polygon from their star polygons also finds the rotational geodesics of any polytope of any dimensionality.</blockquote> == Introduction == Steinbach discovered the Diagonal Product Formula and the Golden Fields family of ratios of diagonal to side in the regular polygons. He showed how this family extends beyond the pentagon {5} with its well-known golden bisection proportional to 𝜙, finding that the heptagon {7} has an analogous trisection, the nonagon {9} has an analogous quadrasection, and the hendecagon {11} has an analogous pentasection, an extended family of golden proportions with quasiperiodic properties. Kappraff and Adamson extended these findings in plane geometry to a theory of Generalized Fibonacci Sequences, showing that the Golden Fields not only do not end with the hendecagon, they form an infinite number of periodic trajectories when operated on by the Mandelbrot operator. They found a relation between the edges of star polygons and dynamical systems in the state of chaos, revealing a connection between chaos theory, number, and rotations in Coxeter Euclidean geometry. Fontaine and Hurley examined Steinbach's finding that the length of each chord of a regular polygon is both the product of two chords and the sum of a set of smaller chords, so that in rotations to add is to multiply. They illustrated Steinbach's sets of additive chords lying parallel to each other in the plane (pointing in the same direction), and by applying Steinbach's formula more generally they found another summation relation of signed parallel chords (pointing in opposite directions) which relates each chord length to its reciprocal, and relates the summation to a distinct star polygon rotation. We examine these remarkable findings (which stem from study of the chords of humble regular polygons) in higher-dimensional spaces, specifically in the chords, polygons and rotations of the [[120-cell]], the largest four-dimensional regular convex polytope. == Visualizing the 120-cell == {| class="wikitable floatright" width="400" |style="vertical-align:top"|[[File:120-cell.gif|200px]]<br>Orthographic projection of the 600-point 120-cell <small><math>\{5,3,3\}</math></small> performing a [[W:SO(4)#Geometry of 4D rotations|simple rotation]].{{Sfn|Hise|2011|loc=File:120-cell.gif|ps=; "Created by Jason Hise with Maya and Macromedia Fireworks.

Therefore even though it is translucent, only its outer surface is visible. The complex interior parts of the 120-cell, all its inscribed 5-cells, 16-cells, 8-cells, 24-cells, 600-cells and its much larger inventory of polyhedra, are completely invisible in this view, as none of their edges are rendered at all. |style="vertical-align:top"|[[File:Ortho solid 016-uniform polychoron p33-t0.png|200px]]<br>Orthographic projection of the 600-point [[W:Great grand stellated 120-cell|great grand stellated 120-cell]] <small><math>\{\tfrac{5}{2},3,3\}</math></small>.{{Sfn|Ruen: Great grand stellated 120-cell|2007}} The 120-cell is its convex hull.

The 120-cell is the convex hull of a regular [[120-cell#Relationships among interior polytopes|compound of each of the 6 regular convex 4-polytopes]]. They are the [[5-cell|5-point (5-cell) 4-simplex]], the [[16-cell|8-point (16-cell) 4-orthoplex]], the [[W:Tesseract|16-point (8-cell) tesseract]], the [[24-cell|24-point (24-cell)]], the [[600-cell|120-point (600-cell)]], and the [[120-cell|600-point (120-cell)]]. The 120-cell is the convex hull of a compound of 120 disjoint regular 5-cells, of 75 disjoint 16-cells, of 25 disjoint 24-cells, and of 5 disjoint 600-cells. The 120-cell contains an even larger inventory of irregular polytopes, created by the intersection of multiple instances of these component regular 4-polytopes. Many are quite unexpected, because they do not occur as components of any regular polytope smaller than the 120-cell. As just one example among the [[120-cell#Concentric hulls|sections of the 120-cell]], there is an irregular 24-point polyhedron with 16 triangle faces and 4 nonagon {9} faces.{{Sfn|Moxness|}} Most renderings of the 120-cell, like the rotating projection here, only illustrate its outer surface, which is a honeycomb of face-bonded dodecahedral cells. Only the objects in its 3-dimensional surface are rendered, namely the 120 dodecahedra, their pentagon faces, and their edges. Although the 120-cell has chords of 30 distinct lengths, in this kind of simplified rendering only the 120-cell's own edges (its shortest chord) are shown. Its 29 interior chords, the edges of objects in the interior of the 120-cell, are not rendered, so interior objects are not visible at all. Visualizing the complete interior of the 600-vertex 120-cell in a single image is impractical because of its complexity. Only four 120-cell edges are incident at each vertex, but [[120-cell#Chords|600 chords (of all 30 lengths)]] are incident at ''each'' vertex. == Compounds in the 120-cell == The 8-point (16-cell), not the 5-point (5-cell), is the smallest building block; it compounds to every larger regular 4-polytope. The 5-point (5-cell) does compound to the 600-point (120-cell), but it does not fit into any smaller regular 4-polytope. The 8-point (16-cell) compounds by 2 in the 16-point (8-cell), and by 3 in the 24-point (24-cell). The 16-point (8-cell) compounds in the 24-point (24-cell) by 3 non-disjoint instances of itself, with each of the 24 vertices shared by two 16-point (8-cells). The 24-point (24-cell) compounds by 5 disjoint instances of itself in the 120-point (600-cell), and the 120-point (600-cell) compounds by 5 disjoint instances of itself in the 600-point (120-cell). The 24-point (24-cell) also compounds by <math>5^2</math> non-disjoint instances of itself in the 120-point (600-cell); it compounds in 5 disjoint instances of itself, 10 (not 5) different ways. Whichever set of 5 disjoint 24-point (24-cells) are assembled, the resulting 120-point (600-cell) contains 25 distinct 24-point (24-cells), not just 5 (or 10). This implies that 15 disjoint 8-point (16-cells) will construct a 120-point (600-cell), which will contain 75 distinct 8-point (16-cells). The 600-point (120-cell) is 5 disjoint 120-point (600-cells), just 2 different ways (not 5 or 10 ways), so it is 10 distinct 120-point (600-cells). This implies that the 8-point (16-cell) compounds by 3 times <math>5^2</math> (75) disjoint instances of itself in the 600-point (120-cell), which contains <math>3^2</math> times <math>5^2</math> (225) distinct instances of the 24-point (24-cell), and <math>3^3</math> times <math>5^2</math> (675) distinct instances of the 8-point (16-cell). These facts were discovered painstakingly by various researchers, and no one has found a general rule governing subsumption relations among regular polytopes. The reasons for some of their numeric incidence relations are far from obvious. [[W:Pieter Hendrik Schoute|Schoute]] was the first to see that the 120-point (600-cell) is a compound of 5 24-point (24-cells) ''10 different ways'', and after he saw it a hundred years lapsed until Denney, Hooker, Johnson, Robinson, Butler & Claiborne proved his result, and showed why.{{Sfn|Denney, Hooker, Johnson, Robinson, Butler & Claiborne|2020|loc=''The geometry of H4 polytopes''}} So much for the compounds of 16-cells. The 120-cell is also the convex hull of the compound of 120 disjoint regular 5-cells. That stellated compound (without its convex hull of 120-cell edges) is the [[w:Great_grand_stellated_120-cell|great grand stellated 120-cell]] illustrated above, the final regular [[W:Stellation|stellation]] of the 120-cell, and the only [[W:Schläfli-Hess polychoron|regular star 4-polytope]] to have the 120-cell for its convex hull. The edges of the great grand stellated 120-cell are <math>\phi^6</math> as long as those of its 120-cell [[W:List of polyhedral stellations#Stellation process|stellation core]] deep inside. The compound of 120 disjoint 5-point (5-cells) can be seen to be equivalent to the compound of 5 disjoint 120-point (600-cells), as follows. Beginning with a single 120-point (600-cell), expand each vertex into a regular 5-cell, by adding 4 new equidistant vertices, such that the 5 vertices form a regular 5-cell inscribed in the 3-sphere. The 120 5-cells are disjoint, and the 600 vertices form 5 disjoint 120-point (600-cells): a 120-cell. == Thirty distinguished distances == The 30 numbers listed in the table are all-important in Euclidean geometry. A case can be made on symmetry grounds that their squares are the 30 most important numbers between 0 and 4. The 30 rows of the table are the 30 distinct [[120-cell#Geodesic rectangles|chord lengths of the unit-radius 120-cell]], the largest regular convex 4-polytope. Since the 120-cell subsumes all smaller regular polytopes, its 30 chords are the complete chord set of all the regular polytopes that can be constructed in the first four dimensions of Euclidean space, except for regular polygons of more than 15 sides. {| class="wikitable" style="white-space:nowrap;text-align:center" !rowspan=2|<math>c_t</math> !rowspan=2|arc

regular polytopes == In 2-space we have the regular 8-point octagon, in 3-space the regular 8-point cube, and in 4-space the regular 8-point [[16-cell]]. A planar octagon with rigid edges of unit length has chords of length: :<math>r_1=1,r_2=\sqrt{2+\sqrt{2}} \approx 1.84776,r_3=1+\sqrt{2} \approx 2.41421,r_4=\sqrt{4 + \sqrt{8}} \approx 2.61313</math> The chord ratio <math>r_3=1+\sqrt{2}</math> is a geometrical proportion, the [[W:Silver ratio|silver ratio]]. Fontaine and Hurley's procedure for obtaining the reciprocal of a chord tells us that: :<math>r_3-r_1-r_1=1/r_3 \approx 0.41421</math> Note that <math>1/r_3=\sqrt{2}-1=r_3-2</math>. If we embed this planar octagon in 3-space, we can make it skew, repositioning its vertices so that each is one unit-edge length distant from three others instead of two others, at the vertices of a unit-edge cube with chords of length: :<math>r_1=1, r_2=\sqrt{2}, r_3=\sqrt{3}, r_4=\sqrt{2}</math> If we embed this cube in 4-space, we can skew it some more, repositioning its vertices so that each is one unit-edge length distant from six others instead of three others, at the vertices of a unit-edge 4-polytope with chords of length: :<math>r_1=1,r_2=1,r_3=1,r_4=\sqrt{2}</math> All of its chords except its long diameters are the same unit length as its edge. In fact they are its 24 edges, and it is a 16-cell of radius <small><math>1/\sqrt{2}</math></small>. [[File:octagon16cell.png|thumb|Orthogonal projection of a regular 16-cell to the [[16-cell#Projections|B<sub>4</sub> Coxeter plane]]. Only its edges are shown; its long diameter chords are not drawn. All 24 edges are the same length. Only the edges of the two disjoint squares lie parallel to the projection plane, in completely orthogonal central planes.]] The [[16-cell]] is the [[W:Regular convex 4-polytope|regular convex 4-polytope]] with [[W:Schläfli symbol|Schläfli symbol]] {3,3,4}. It has 8 vertices, 24 edges, 32 equilateral triangle faces, and 16 regular tetrahedron cells. It is the [[16-cell#Octahedral dipyramid|four-dimensional analogue of the octahedron]], and each of its four orthogonal central hyperplanes is an octahedron. The only planar regular polygons found in the 16-cell are face triangles and central plane squares, but the 16-cell also contains a skew regular octagon, its [[W:Petrie polygon|Petrie polygon]]. The chords of this regular octagon, which lies skew in 4-space, are those given above for the 16-cell, as opposed to those for the cube or the regular octagon in the plane. The 16-cell is a construct of 3 Petrie octagons which share the same 8 vertices but have disjoint sets of 8 edges each. The regular octad has higher symmetry in 4-space than it does in 2-space. The 16-cell is the 4-orthoplex, the simplest regular 4-polytope after the [[5-cell|4-simplex]]. All the larger regular 4-polytopes, including the 120-cell, are compounds of the 16-cell. The regular octagon exhibits this high symmetry only when embedded in 4-space at the vertices of the 16-cell. The 16-cell constitutes an [[W:Orthonormal basis|orthonormal basis]] for the choice of a 4-dimensional Cartesian reference frame, because its vertices define four orthogonal axes. The eight vertices of a unit-radius 16-cell are (±1, 0, 0, 0), (0, ±1, 0, 0), (0, 0, ±1, 0), (0, 0, 0, ±1). All vertices are connected by <small><math>\sqrt{2}</math></small> edges except opposite pairs. The vertex coordinates of the 16-cell form 6 central squares lying in 6 pairwise [[W:Orthogonal|orthogonal]] coordinate planes. Great squares in ''opposite'' planes that do not share an axis (e.g. in the ''xy'' and ''wz'' planes) are completely disjoint (they do not intersect at any vertices). These planes are [[W:Completely orthogonal|completely orthogonal]].{{Efn|name=Six orthogonal planes of the Cartesian basis}} Since this unit-radius coordinate system is convenient, let us derive the unit-radius 16-cell by skewing a unit-radius planar octagon, which has chords of length: :<math>r_1=\sqrt{2-\sqrt{2}} \approx 0.76537,r_2=\sqrt{2},r_3=\sqrt{2+\sqrt{2}} \approx 1.84776,r_4=2</math> We will need a planar octagon with rigid <math>r_2</math> chords, rather than one with rigid <math>r_1</math> edges. The octagon's <math>r_2</math> chords form two disjoint great squares, visible in the orthogonal projection, which we can reposition in 3-space to form a cube by making them parallel, and in 4-space to form a 16-cell by making them completely orthogonal. In the 16-cell the two disjoint great squares formed by the <math>r_2</math> chords are both parallel and perpendicular to each other. A ''simple'' rotation of the 16-cell in ''one'' of those two central planes rotates that square like a wheel, while the other square does not move. The four vertices of the rotating square orbit on a great circle in the plane. The <math>r_1</math> chords of the 16-cell form a Petrie polygon which zig-zags back and forth between the two completely orthogonal <math>r_2</math> squares. The <math>r_3</math> chords of the 16-cell form a circular helix, visible as a skew {8/3} octagram in the orthogonal projection. A ''double'' rotation of the 16-cell, in ''both'' of the two completely orthogonal <math>r_2</math> central square planes at once by the same angle, moves the eight vertices along the circular helix over the <math>r_3</math> chords. The circular helix is a [[w:Geodesic|geodesic]] great circle on the 3-sphere of a special kind: it does not lie in a single central plane, its circumference is <math>4 \pi</math>, and it occurs in either a left or right hand chiral form. [[W:Rotations in 4-dimensional Euclidean space|Rotations in 4-dimensional Euclidean space]] can be seen as the composition of two 2-dimensional rotations in completely orthogonal planes. The general rotation in 4-space is a double rotation in pairs of completely orthogonal planes. Two completely orthogonal planes are called invariant planes of the rotation when all points in the plane rotate on circles that remain in the plane, even as the whole plane tilts sideways (like a coin flipping) into another plane. The two completely orthogonal rotations of each plane (like a wheel, and like a coin flipping) are simultaneous but independent, in that they are not geometrically constrained to turn at the same rate. However, the most circular kind of rotation (as opposed to an elliptical double rotation of a rigid spherical object) occurs when the invariant planes do rotate through the same angle in the same time interval. Such equi-angled double rotations are called [[w:SO(4)#Isoclinic_rotations|isoclinic]], also [[w:William_Kingdon_Clifford|Clifford]] displacements. The 16-cell is the simplest possible frame in which to [[16-cell#Rotations|observe 4-dimensional rotations]] because its characteristic rotations feature a single pair of invariant rotation planes. In the 16-cell an isoclinic rotation by 90° in any pair of invariant completely orthogonal square central planes takes every square central plane to its completely orthogonal square central plane in a twisting displacement, as they tilt sideways 90° into each other's plane while rotating 90° internally. All the vertices move at once on the same circular helix geodesic, displaced 90° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. When the 90° isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 90°, but from the new orientation in a direction orthogonal to its first 90° displacement. After 360° of rotation each vertex reaches its antipodal position. The trajectory of each vertex over each 90° isoclinic rotational displacement is a one-eighth segment of its geodesic orbit. Its entire orbit traces a circular helix in 4-space over eight <math>r_3</math> chords, and also traces an ordinary great circle twice over the four <math>r_2</math> chords within one of the two moving invariant rotation planes. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once and returns to its original position, and the 16-cell returns to its original orientation. == Hypercubes == The long diameter of the unit-edge [[W:Hypercube|hypercube]] of dimension <small><math>n</math></small> is <small><math>\sqrt{n}</math></small>, so the unit-edge [[w:Tesseract|4-hypercube, the 16-point (8-cell) tesseract,]] has chords: :<math>r_1=\sqrt{1},r_2=\sqrt{2},r_3=\sqrt{3},r_4=\sqrt{4}</math> Uniquely in its 4-dimensional case, the hypercube's edge length equals its radius, like the hexagon. We call such polytopes ''radially equilateral'', because they can be constructed from equilateral triangles which meet at their center, each contributing two radii and an edge. The cuboctahedron and the 24-cell are also radially equilateral. The [[W:Tesseract|tesseract]] is the [[W:Regular convex 4-polytope|regular convex 4-polytope]] with [[W:Schläfli symbol|Schläfli symbol]] {4,3,3}. It has 16 vertices, 32 edges, 24 square faces, and 8 cube cells. It is the four-dimensional analogue of the cube. The tesseract is the [[W:Dual polytope|dual polytope]] of the 16-cell. They have the same Petrie polygon, the regular octagon, but the tesseract contains 2 disjoint instances and 4 distinct instances of the skew octagon. We can construct the tesseract by skewing two planar octagons. Because the tesseract is radially equilateral (unlike the 16-cell), we start with our original octagon of unit-edge length, rather than the octagon of edge length <small><math>\sqrt{2}</math></small> that we needed to build the unit-radius 16-cell. For our tesseract construction we skew each planar octagon into a cube, so we have a compound of two completely orthogonal cubes. Provided the planes were completely orthogonal in 4-space and we skewed them both the same way, the 16 vertices will be the vertices of a tesseract with half of its 32 edges missing. The 16-point tesseract is the convex hull of a compound of two 8-point 16-cells, in exact dimensional analogy to the way the 8-point cube is the convex hull of a [[W:Stellated octahedron|compound of two regular 4-point tetrahedra]]. The [[W:Demihypercube|demihypercubes]] occupy alternate vertices of the hypercubes. The diagonals of the square faces of the unit-radius tesseract are the <small><math>\sqrt{2}</math></small> edges of two unit-radius 16-cells, which are also the edges of the square central planes. Because the tesseract contains two 16-cells in alternate positions it has two sets of 6 orthogonal square central planes. Two angles are required to specify the relationship between two planes in 4-space. Pairs of planes within each 16-cell are 90° apart in one angle, and either 0° or 90° apart in the other angle. They are 90° apart in both angles if and only if they are completely orthogonal planes, 90° apart by isoclinic rotation, with no vertices in common and their corresponding vertices 180° apart. Otherwise they are 0° apart in one of the angles, 90° apart by simple rotation with their corresponding vertices 90° apart, and they intersect in one axis and lie in a common 3-dimensional hyperplane.{{Efn|A double rotation in which one of the two angles of rotation is 0°, so that one of the completely orthogonal invariant planes does not rotate, is called a simple rotation. Ordinary rotations observed in a 3-dimensional space are simple rotations.}} A pair of square central planes from alternate 16-cells are 60° apart by isoclinic rotation, with their corresponding vertices 120° apart. The planes are not orthogonal or parallel, so they intersect in a line somewhere, but they have no vertices in common, they have no 3-dimensional hyperplane in common, and they cannot reach each other by simple rotation. Such pairs of objects are called [[W:Clifford parallel|Clifford parallel]] because all their corresponding pairs of vertices are the same distance apart, although they are not parallel in the usual sense, because they have a common center. Not only the alternate 16-cells' corresponding square central planes, but also the 16-cells themselves, are Clifford parallel objects. We can rotate the tesseract isoclinically the way we rotated the 16-cell, by 90° in two completely orthogonal invariant square central planes, with the same effect on both alternate 16-cells. In the course of a 720° isoclinic rotation in invariant square central planes each vertex departs from all 8 vertex positions of its 16-cell just once and returns to its original position, but it does not visit the vertex positions of the other 16-cell. The skew octagon geodesic orbits of the 16 vertices lie on two disjoint octagram circular helixes of the same chirality, which are Clifford parallel objects that form a circular double helix. == The 24-cell == In 2-space we have the radially equilateral 6-point hexagon. In 3-space we have the radially equilateral 12-point cuboctahedron, with 4 hexagonal central planes. In 4-space we have the radially equilateral 24-point 24-cell, with 4 cuboctahedral central hyperplanes and 16 hexagonal central planes. Great hexagons are a rounder choice than great squares for the invariant rotation planes in which to rotate a 4-polytope isoclinically. The complete hexagonal isoclinic revolution requires 720° like the square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 90° each. ... == The 600-cell == ... == Finally the 120-cell == ... == Conclusions == Fontaine and Hurley's discovery is more than a formula for the reciprocal of a regular ''n''-polygon diagonal. It also yields the discrete sequence of isocline chords of the distinct isoclinic rotation characteristic of a ''d''-dimensional regular polytope. The characteristic rotational chord sequence of the ''d''-polytope can be represented geometrically in two dimensions on a distinct star polygon, but it lies on a geodesic circle through ''d''-dimensional space. Fontaine and Hurley discovered the geodesic topology of polytopes generally. Their procedure will reveal the geodesics of arbitrary non-uniform polytopes, since it can be applied to a polytope of any dimensionality and irregularity, by first fitting the polytope to the smallest regular polygon whose chords include its chords. Fontaine and Hurley's discovery of a chordal formula for isoclinic rotations closes the circuit on Kappraff and Adamson's discovery of a rotational connection between dynamical systems, Steinbach's golden fields, and Coxeter's Euclidean geometry of ''n'' dimensions. Application of the Fontaine and Hurley procedure in higher-dimensional spaces demonstrates why the connection exists: because polytope sequences generally, from Steinbach's golden polygon chord sequences, to chord sequences in isoclinic rotation helixes, to subsumption relations in the sequence of regular 4-polytopes, arise as expressions of the reflections and rotations of distinct Coxeter symmetry groups, when those various groups interact. == Appendix: Sequence of regular 4-polytopes == {{Regular convex 4-polytopes|wiki=W:|columns=7}} == Notes == {{Notelist}} == Citations == {{Reflist}} == References == {{Refbegin}} * {{Cite journal | last=Steinbach | first=Peter | year=1997 | title=Golden fields: A case for the Heptagon | journal=Mathematics Magazine | volume=70 | issue=Feb 1997 | pages=22–31 | doi=10.1080/0025570X.1997.11996494 | jstor=2691048 | ref={{SfnRef|Steinbach|1997}} }} * {{Cite journal | last=Steinbach | first=Peter | year=2000 | title=Sections Beyond Golden| journal=Bridges: Mathematical Connections in Art, Music and Science | issue=2000 | pages=35-44 | url=https://archive.bridgesmathart.org/2000/bridges2000-35.pdf | ref={{SfnRef|Steinbach|2000}}}} * {{Cite journal | last1=Kappraff | first1=Jay | last2=Jablan | first2=Slavik | last3=Adamson | first3=Gary | last4=Sazdanovich | first4=Radmila | year=2004 | title=Golden Fields, Generalized Fibonacci Sequences, and Chaotic Matrices | journal=Forma | volume=19 | pages=367-387 | url=https://archive.bridgesmathart.org/2005/bridges2005-369.pdf | ref={{SfnRef|Kappraff, Jablan, Adamson & Sazdanovich|2004}} }} * {{Cite journal | last1=Kappraff | first1=Jay | last2=Adamson | first2=Gary | year=2004 | title=Polygons and Chaos | journal=Dynamical Systems and Geometric Theories | url=https://archive.bridgesmathart.org/2001/bridges2001-67.pdf | ref={{SfnRef|Kappraff & Adamson|2004}} }} * {{Cite journal | last1=Fontaine | first1=Anne | last2=Hurley | first2=Susan | year=2006 | title=Proof by Picture: Products and Reciprocals of Diagonal Length Ratios in the Regular Polygon | journal=Forum Geometricorum | volume=6 | pages=97-101 | url=https://scispace.com/pdf/proof-by-picture-products-and-reciprocals-of-diagonal-length-1aian8mgp9.pdf }} {{Refend}} junfaj2on33de43kmqiambn5hkzqpix 2809825 2809824 2026-05-17T03:34:48Z Dc.samizdat 2856930 /* The 8-point regular polytopes */ 2809825 wikitext text/x-wiki {{align|center|David Brooks Christie}} {{align|center|dc@samizdat.org}} {{align|center|Draft in progress}} {{align|center|January 2026 - April 2026}} <blockquote>Steinbach discovered the formula for the ratios of diagonal to side in the regular polygons. Fontaine and Hurley extended this result, discovering a formula for the reciprocal of a regular polygon chord derived geometrically from the chord's star polygon. We observe that these findings in plane geometry apply more generally, to polytopes of any dimensionality. Fontaine and Hurley's geometric procedure for finding the reciprocals of the chords of a regular polygon from their star polygons also finds the rotational geodesics of any polytope of any dimensionality.</blockquote> == Introduction == Steinbach discovered the Diagonal Product Formula and the Golden Fields family of ratios of diagonal to side in the regular polygons. He showed how this family extends beyond the pentagon {5} with its well-known golden bisection proportional to 𝜙, finding that the heptagon {7} has an analogous trisection, the nonagon {9} has an analogous quadrasection, and the hendecagon {11} has an analogous pentasection, an extended family of golden proportions with quasiperiodic properties. Kappraff and Adamson extended these findings in plane geometry to a theory of Generalized Fibonacci Sequences, showing that the Golden Fields not only do not end with the hendecagon, they form an infinite number of periodic trajectories when operated on by the Mandelbrot operator. They found a relation between the edges of star polygons and dynamical systems in the state of chaos, revealing a connection between chaos theory, number, and rotations in Coxeter Euclidean geometry. Fontaine and Hurley examined Steinbach's finding that the length of each chord of a regular polygon is both the product of two chords and the sum of a set of smaller chords, so that in rotations to add is to multiply. They illustrated Steinbach's sets of additive chords lying parallel to each other in the plane (pointing in the same direction), and by applying Steinbach's formula more generally they found another summation relation of signed parallel chords (pointing in opposite directions) which relates each chord length to its reciprocal, and relates the summation to a distinct star polygon rotation. We examine these remarkable findings (which stem from study of the chords of humble regular polygons) in higher-dimensional spaces, specifically in the chords, polygons and rotations of the [[120-cell]], the largest four-dimensional regular convex polytope. == Visualizing the 120-cell == {| class="wikitable floatright" width="400" |style="vertical-align:top"|[[File:120-cell.gif|200px]]<br>Orthographic projection of the 600-point 120-cell <small><math>\{5,3,3\}</math></small> performing a [[W:SO(4)#Geometry of 4D rotations|simple rotation]].{{Sfn|Hise|2011|loc=File:120-cell.gif|ps=; "Created by Jason Hise with Maya and Macromedia Fireworks.

Therefore even though it is translucent, only its outer surface is visible. The complex interior parts of the 120-cell, all its inscribed 5-cells, 16-cells, 8-cells, 24-cells, 600-cells and its much larger inventory of polyhedra, are completely invisible in this view, as none of their edges are rendered at all. |style="vertical-align:top"|[[File:Ortho solid 016-uniform polychoron p33-t0.png|200px]]<br>Orthographic projection of the 600-point [[W:Great grand stellated 120-cell|great grand stellated 120-cell]] <small><math>\{\tfrac{5}{2},3,3\}</math></small>.{{Sfn|Ruen: Great grand stellated 120-cell|2007}} The 120-cell is its convex hull.

The 120-cell is the convex hull of a regular [[120-cell#Relationships among interior polytopes|compound of each of the 6 regular convex 4-polytopes]]. They are the [[5-cell|5-point (5-cell) 4-simplex]], the [[16-cell|8-point (16-cell) 4-orthoplex]], the [[W:Tesseract|16-point (8-cell) tesseract]], the [[24-cell|24-point (24-cell)]], the [[600-cell|120-point (600-cell)]], and the [[120-cell|600-point (120-cell)]]. The 120-cell is the convex hull of a compound of 120 disjoint regular 5-cells, of 75 disjoint 16-cells, of 25 disjoint 24-cells, and of 5 disjoint 600-cells. The 120-cell contains an even larger inventory of irregular polytopes, created by the intersection of multiple instances of these component regular 4-polytopes. Many are quite unexpected, because they do not occur as components of any regular polytope smaller than the 120-cell. As just one example among the [[120-cell#Concentric hulls|sections of the 120-cell]], there is an irregular 24-point polyhedron with 16 triangle faces and 4 nonagon {9} faces.{{Sfn|Moxness|}} Most renderings of the 120-cell, like the rotating projection here, only illustrate its outer surface, which is a honeycomb of face-bonded dodecahedral cells. Only the objects in its 3-dimensional surface are rendered, namely the 120 dodecahedra, their pentagon faces, and their edges. Although the 120-cell has chords of 30 distinct lengths, in this kind of simplified rendering only the 120-cell's own edges (its shortest chord) are shown. Its 29 interior chords, the edges of objects in the interior of the 120-cell, are not rendered, so interior objects are not visible at all. Visualizing the complete interior of the 600-vertex 120-cell in a single image is impractical because of its complexity. Only four 120-cell edges are incident at each vertex, but [[120-cell#Chords|600 chords (of all 30 lengths)]] are incident at ''each'' vertex. == Compounds in the 120-cell == The 8-point (16-cell), not the 5-point (5-cell), is the smallest building block; it compounds to every larger regular 4-polytope. The 5-point (5-cell) does compound to the 600-point (120-cell), but it does not fit into any smaller regular 4-polytope. The 8-point (16-cell) compounds by 2 in the 16-point (8-cell), and by 3 in the 24-point (24-cell). The 16-point (8-cell) compounds in the 24-point (24-cell) by 3 non-disjoint instances of itself, with each of the 24 vertices shared by two 16-point (8-cells). The 24-point (24-cell) compounds by 5 disjoint instances of itself in the 120-point (600-cell), and the 120-point (600-cell) compounds by 5 disjoint instances of itself in the 600-point (120-cell). The 24-point (24-cell) also compounds by <math>5^2</math> non-disjoint instances of itself in the 120-point (600-cell); it compounds in 5 disjoint instances of itself, 10 (not 5) different ways. Whichever set of 5 disjoint 24-point (24-cells) are assembled, the resulting 120-point (600-cell) contains 25 distinct 24-point (24-cells), not just 5 (or 10). This implies that 15 disjoint 8-point (16-cells) will construct a 120-point (600-cell), which will contain 75 distinct 8-point (16-cells). The 600-point (120-cell) is 5 disjoint 120-point (600-cells), just 2 different ways (not 5 or 10 ways), so it is 10 distinct 120-point (600-cells). This implies that the 8-point (16-cell) compounds by 3 times <math>5^2</math> (75) disjoint instances of itself in the 600-point (120-cell), which contains <math>3^2</math> times <math>5^2</math> (225) distinct instances of the 24-point (24-cell), and <math>3^3</math> times <math>5^2</math> (675) distinct instances of the 8-point (16-cell). These facts were discovered painstakingly by various researchers, and no one has found a general rule governing subsumption relations among regular polytopes. The reasons for some of their numeric incidence relations are far from obvious. [[W:Pieter Hendrik Schoute|Schoute]] was the first to see that the 120-point (600-cell) is a compound of 5 24-point (24-cells) ''10 different ways'', and after he saw it a hundred years lapsed until Denney, Hooker, Johnson, Robinson, Butler & Claiborne proved his result, and showed why.{{Sfn|Denney, Hooker, Johnson, Robinson, Butler & Claiborne|2020|loc=''The geometry of H4 polytopes''}} So much for the compounds of 16-cells. The 120-cell is also the convex hull of the compound of 120 disjoint regular 5-cells. That stellated compound (without its convex hull of 120-cell edges) is the [[w:Great_grand_stellated_120-cell|great grand stellated 120-cell]] illustrated above, the final regular [[W:Stellation|stellation]] of the 120-cell, and the only [[W:Schläfli-Hess polychoron|regular star 4-polytope]] to have the 120-cell for its convex hull. The edges of the great grand stellated 120-cell are <math>\phi^6</math> as long as those of its 120-cell [[W:List of polyhedral stellations#Stellation process|stellation core]] deep inside. The compound of 120 disjoint 5-point (5-cells) can be seen to be equivalent to the compound of 5 disjoint 120-point (600-cells), as follows. Beginning with a single 120-point (600-cell), expand each vertex into a regular 5-cell, by adding 4 new equidistant vertices, such that the 5 vertices form a regular 5-cell inscribed in the 3-sphere. The 120 5-cells are disjoint, and the 600 vertices form 5 disjoint 120-point (600-cells): a 120-cell. == Thirty distinguished distances == The 30 numbers listed in the table are all-important in Euclidean geometry. A case can be made on symmetry grounds that their squares are the 30 most important numbers between 0 and 4. The 30 rows of the table are the 30 distinct [[120-cell#Geodesic rectangles|chord lengths of the unit-radius 120-cell]], the largest regular convex 4-polytope. Since the 120-cell subsumes all smaller regular polytopes, its 30 chords are the complete chord set of all the regular polytopes that can be constructed in the first four dimensions of Euclidean space, except for regular polygons of more than 15 sides. {| class="wikitable" style="white-space:nowrap;text-align:center" !rowspan=2|<math>c_t</math> !rowspan=2|arc

regular polytopes == In 2-space we have the regular 8-point octagon, in 3-space the regular 8-point cube, and in 4-space the regular 8-point [[16-cell]]. A planar octagon with rigid edges of unit length has chords of length: :<math>r_1=1,r_2=\sqrt{2+\sqrt{2}} \approx 1.84776,r_3=1+\sqrt{2} \approx 2.41421,r_4=\sqrt{4 + \sqrt{8}} \approx 2.61313</math> The chord ratio <math>r_3=1+\sqrt{2}</math> is a geometrical proportion, the [[W:Silver ratio|silver ratio]]. Fontaine and Hurley's procedure for obtaining the reciprocal of a chord tells us that: :<math>r_3-r_1-r_1=1/r_3 \approx 0.41421</math> Note that <math>1/r_3=\sqrt{2}-1=r_3-2</math>. If we embed this planar octagon in 3-space, we can make it skew, repositioning its vertices so that each is one unit-edge length distant from three others instead of two others, at the vertices of a unit-edge cube with chords of length: :<math>r_1=1, r_2=\sqrt{2}, r_3=\sqrt{3}, r_4=\sqrt{2}</math> If we embed this cube in 4-space, we can skew it some more, repositioning its vertices so that each is one unit-edge length distant from six others instead of three others, at the vertices of a unit-edge 4-polytope with chords of length: :<math>r_1=1,r_2=1,r_3=1,r_4=\sqrt{2}</math> All of its chords except its long diameters are the same unit length as its edge. In fact they are its 24 edges, and it is a 16-cell of radius <small><math>1/\sqrt{2}</math></small>. [[File:octagon16cell.png|thumb|Orthogonal projection of a regular 16-cell to the [[16-cell#Projections|B<sub>4</sub> Coxeter plane]]. Only its edges are shown; its long diameter chords are not drawn. All 24 edges are the same length. Only the edges of the two disjoint squares lie parallel to the projection plane, in completely orthogonal central planes.]] The [[16-cell]] is the [[W:Regular convex 4-polytope|regular convex 4-polytope]] with [[W:Schläfli symbol|Schläfli symbol]] {3,3,4}. It has 8 vertices, 24 edges, 32 equilateral triangle faces, and 16 regular tetrahedron cells. It is the [[16-cell#Octahedral dipyramid|four-dimensional analogue of the octahedron]], and each of its four orthogonal central hyperplanes is an octahedron. The only planar regular polygons found in the 16-cell are face triangles and central plane squares, but the 16-cell also contains a skew regular octagon, its [[W:Petrie polygon|Petrie polygon]]. The chords of this regular octagon, which lies skew in 4-space, are those given above for the 16-cell, as opposed to those for the cube or the regular octagon in the plane. The 16-cell is a construct of 3 Petrie octagons which share the same 8 vertices but have disjoint sets of 8 edges each. The regular octad has higher symmetry in 4-space than it does in 2-space. The 16-cell is the 4-orthoplex, the simplest regular 4-polytope after the [[5-cell|4-simplex]]. All the larger regular 4-polytopes, including the 120-cell, are compounds of the 16-cell. The regular octagon exhibits this high symmetry only when embedded in 4-space at the vertices of the 16-cell. The 16-cell constitutes an [[W:Orthonormal basis|orthonormal basis]] for the choice of a 4-dimensional Cartesian reference frame, because its vertices define four orthogonal axes. The eight vertices of a unit-radius 16-cell are (±1, 0, 0, 0), (0, ±1, 0, 0), (0, 0, ±1, 0), (0, 0, 0, ±1). All vertices are connected by <small><math>\sqrt{2}</math></small> edges except opposite pairs. The vertex coordinates of the 16-cell form 6 central squares lying in 6 pairwise [[W:Orthogonal|orthogonal]] coordinate planes. Great squares in ''opposite'' planes that do not share an axis (e.g. in the ''xy'' and ''wz'' planes) are completely disjoint (they do not intersect at any vertices). These planes are [[W:Completely orthogonal|completely orthogonal]].{{Efn|name=Six orthogonal planes of the Cartesian basis}} Since this unit-radius coordinate system is convenient, let us derive the unit-radius 16-cell by skewing a unit-radius planar octagon, which has chords of length: :<math>r_1=\sqrt{2-\sqrt{2}} \approx 0.76537,r_2=\sqrt{2},r_3=\sqrt{2+\sqrt{2}} \approx 1.84776,r_4=2</math> We will need a planar octagon with rigid <math>r_2</math> chords, rather than one with rigid <math>r_1</math> edges. The octagon's <math>r_2</math> chords form two disjoint great squares, visible in the orthogonal projection, which we can reposition in 3-space to form a cube by making them parallel, and in 4-space to form a 16-cell by making them completely orthogonal. In the 16-cell the two completely orthogonal great squares formed by the <math>r_2</math> chords are both parallel and perpendicular to each other. A ''simple'' rotation of the 16-cell in ''one'' of those two central planes rotates that square like a wheel, while the other square does not move. The four vertices of the rotating square orbit on a great circle in the plane. The <math>r_1</math> chords of the 16-cell form a Petrie polygon which zig-zags back and forth between the two completely orthogonal <math>r_2</math> squares. The <math>r_3</math> chords of the 16-cell form a circular helix, visible as a skew {8/3} octagram in the orthogonal projection. A ''double'' rotation of the 16-cell, in ''both'' of the two completely orthogonal <math>r_2</math> central square planes at once by the same angle, moves the eight vertices along the circular helix over the <math>r_3</math> chords. The circular helix is a [[w:Geodesic|geodesic]] great circle on the 3-sphere of a special kind: it does not lie in a single central plane, its circumference is <math>4 \pi</math>, and it occurs in either a left or right hand chiral form. [[W:Rotations in 4-dimensional Euclidean space|Rotations in 4-dimensional Euclidean space]] can be seen as the composition of two 2-dimensional rotations in completely orthogonal planes. The general rotation in 4-space is a double rotation in pairs of completely orthogonal planes. Two completely orthogonal planes are called invariant planes of the rotation when all points in the plane rotate on circles that remain in the plane, even as the whole plane tilts sideways (like a coin flipping) into another plane. The two completely orthogonal rotations of each plane (like a wheel, and like a coin flipping) are simultaneous but independent, in that they are not geometrically constrained to turn at the same rate. However, the most circular kind of rotation (as opposed to an elliptical double rotation of a rigid spherical object) occurs when the invariant planes do rotate through the same angle in the same time interval. Such equi-angled double rotations are called [[w:SO(4)#Isoclinic_rotations|isoclinic]], also [[w:William_Kingdon_Clifford|Clifford]] displacements. The 16-cell is the simplest possible frame in which to [[16-cell#Rotations|observe 4-dimensional rotations]] because its characteristic rotations feature a single pair of invariant rotation planes. In the 16-cell an isoclinic rotation by 90° in any pair of invariant completely orthogonal square central planes takes every square central plane to its completely orthogonal square central plane in a twisting displacement, as they tilt sideways 90° into each other's plane while rotating 90° internally. All the vertices move at once on the same circular helix geodesic, displaced 90° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. When the 90° isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 90°, but from the new orientation in a direction orthogonal to its first 90° displacement. After 360° of rotation each vertex reaches its antipodal position. The trajectory of each vertex over each 90° isoclinic rotational displacement is a one-eighth segment of its geodesic orbit. Its entire orbit traces a circular helix in 4-space over eight <math>r_3</math> chords, and also traces an ordinary great circle twice over the four <math>r_2</math> chords within one of the two moving invariant rotation planes. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once and returns to its original position, and the 16-cell returns to its original orientation. == Hypercubes == The long diameter of the unit-edge [[W:Hypercube|hypercube]] of dimension <small><math>n</math></small> is <small><math>\sqrt{n}</math></small>, so the unit-edge [[w:Tesseract|4-hypercube, the 16-point (8-cell) tesseract,]] has chords: :<math>r_1=\sqrt{1},r_2=\sqrt{2},r_3=\sqrt{3},r_4=\sqrt{4}</math> Uniquely in its 4-dimensional case, the hypercube's edge length equals its radius, like the hexagon. We call such polytopes ''radially equilateral'', because they can be constructed from equilateral triangles which meet at their center, each contributing two radii and an edge. The cuboctahedron and the 24-cell are also radially equilateral. The [[W:Tesseract|tesseract]] is the [[W:Regular convex 4-polytope|regular convex 4-polytope]] with [[W:Schläfli symbol|Schläfli symbol]] {4,3,3}. It has 16 vertices, 32 edges, 24 square faces, and 8 cube cells. It is the four-dimensional analogue of the cube. The tesseract is the [[W:Dual polytope|dual polytope]] of the 16-cell. They have the same Petrie polygon, the regular octagon, but the tesseract contains 2 disjoint instances and 4 distinct instances of the skew octagon. We can construct the tesseract by skewing two planar octagons. Because the tesseract is radially equilateral (unlike the 16-cell), we start with our original octagon of unit-edge length, rather than the octagon of edge length <small><math>\sqrt{2}</math></small> that we needed to build the unit-radius 16-cell. For our tesseract construction we skew each planar octagon into a cube, so we have a compound of two completely orthogonal cubes. Provided the planes were completely orthogonal in 4-space and we skewed them both the same way, the 16 vertices will be the vertices of a tesseract with half of its 32 edges missing. The 16-point tesseract is the convex hull of a compound of two 8-point 16-cells, in exact dimensional analogy to the way the 8-point cube is the convex hull of a [[W:Stellated octahedron|compound of two regular 4-point tetrahedra]]. The [[W:Demihypercube|demihypercubes]] occupy alternate vertices of the hypercubes. The diagonals of the square faces of the unit-radius tesseract are the <small><math>\sqrt{2}</math></small> edges of two unit-radius 16-cells, which are also the edges of the square central planes. Because the tesseract contains two 16-cells in alternate positions it has two sets of 6 orthogonal square central planes. Two angles are required to specify the relationship between two planes in 4-space. Pairs of planes within each 16-cell are 90° apart in one angle, and either 0° or 90° apart in the other angle. They are 90° apart in both angles if and only if they are completely orthogonal planes, 90° apart by isoclinic rotation, with no vertices in common and their corresponding vertices 180° apart. Otherwise they are 0° apart in one of the angles, 90° apart by simple rotation with their corresponding vertices 90° apart, and they intersect in one axis and lie in a common 3-dimensional hyperplane.{{Efn|A double rotation in which one of the two angles of rotation is 0°, so that one of the completely orthogonal invariant planes does not rotate, is called a simple rotation. Ordinary rotations observed in a 3-dimensional space are simple rotations.}} A pair of square central planes from alternate 16-cells are 60° apart by isoclinic rotation, with their corresponding vertices 120° apart. The planes are not orthogonal or parallel, so they intersect in a line somewhere, but they have no vertices in common, they have no 3-dimensional hyperplane in common, and they cannot reach each other by simple rotation. Such pairs of objects are called [[W:Clifford parallel|Clifford parallel]] because all their corresponding pairs of vertices are the same distance apart, although they are not parallel in the usual sense, because they have a common center. Not only the alternate 16-cells' corresponding square central planes, but also the 16-cells themselves, are Clifford parallel objects. We can rotate the tesseract isoclinically the way we rotated the 16-cell, by 90° in two completely orthogonal invariant square central planes, with the same effect on both alternate 16-cells. In the course of a 720° isoclinic rotation in invariant square central planes each vertex departs from all 8 vertex positions of its 16-cell just once and returns to its original position, but it does not visit the vertex positions of the other 16-cell. The skew octagon geodesic orbits of the 16 vertices lie on two disjoint octagram circular helixes of the same chirality, which are Clifford parallel objects that form a circular double helix. == The 24-cell == In 2-space we have the radially equilateral 6-point hexagon. In 3-space we have the radially equilateral 12-point cuboctahedron, with 4 hexagonal central planes. In 4-space we have the radially equilateral 24-point 24-cell, with 4 cuboctahedral central hyperplanes and 16 hexagonal central planes. Great hexagons are a rounder choice than great squares for the invariant rotation planes in which to rotate a 4-polytope isoclinically. The complete hexagonal isoclinic revolution requires 720° like the square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 90° each. ... == The 600-cell == ... == Finally the 120-cell == ... == Conclusions == Fontaine and Hurley's discovery is more than a formula for the reciprocal of a regular ''n''-polygon diagonal. It also yields the discrete sequence of isocline chords of the distinct isoclinic rotation characteristic of a ''d''-dimensional regular polytope. The characteristic rotational chord sequence of the ''d''-polytope can be represented geometrically in two dimensions on a distinct star polygon, but it lies on a geodesic circle through ''d''-dimensional space. Fontaine and Hurley discovered the geodesic topology of polytopes generally. Their procedure will reveal the geodesics of arbitrary non-uniform polytopes, since it can be applied to a polytope of any dimensionality and irregularity, by first fitting the polytope to the smallest regular polygon whose chords include its chords. Fontaine and Hurley's discovery of a chordal formula for isoclinic rotations closes the circuit on Kappraff and Adamson's discovery of a rotational connection between dynamical systems, Steinbach's golden fields, and Coxeter's Euclidean geometry of ''n'' dimensions. Application of the Fontaine and Hurley procedure in higher-dimensional spaces demonstrates why the connection exists: because polytope sequences generally, from Steinbach's golden polygon chord sequences, to chord sequences in isoclinic rotation helixes, to subsumption relations in the sequence of regular 4-polytopes, arise as expressions of the reflections and rotations of distinct Coxeter symmetry groups, when those various groups interact. == Appendix: Sequence of regular 4-polytopes == {{Regular convex 4-polytopes|wiki=W:|columns=7}} == Notes == {{Notelist}} == Citations == {{Reflist}} == References == {{Refbegin}} * {{Cite journal | last=Steinbach | first=Peter | year=1997 | title=Golden fields: A case for the Heptagon | journal=Mathematics Magazine | volume=70 | issue=Feb 1997 | pages=22–31 | doi=10.1080/0025570X.1997.11996494 | jstor=2691048 | ref={{SfnRef|Steinbach|1997}} }} * {{Cite journal | last=Steinbach | first=Peter | year=2000 | title=Sections Beyond Golden| journal=Bridges: Mathematical Connections in Art, Music and Science | issue=2000 | pages=35-44 | url=https://archive.bridgesmathart.org/2000/bridges2000-35.pdf | ref={{SfnRef|Steinbach|2000}}}} * {{Cite journal | last1=Kappraff | first1=Jay | last2=Jablan | first2=Slavik | last3=Adamson | first3=Gary | last4=Sazdanovich | first4=Radmila | year=2004 | title=Golden Fields, Generalized Fibonacci Sequences, and Chaotic Matrices | journal=Forma | volume=19 | pages=367-387 | url=https://archive.bridgesmathart.org/2005/bridges2005-369.pdf | ref={{SfnRef|Kappraff, Jablan, Adamson & Sazdanovich|2004}} }} * {{Cite journal | last1=Kappraff | first1=Jay | last2=Adamson | first2=Gary | year=2004 | title=Polygons and Chaos | journal=Dynamical Systems and Geometric Theories | url=https://archive.bridgesmathart.org/2001/bridges2001-67.pdf | ref={{SfnRef|Kappraff & Adamson|2004}} }} * {{Cite journal | last1=Fontaine | first1=Anne | last2=Hurley | first2=Susan | year=2006 | title=Proof by Picture: Products and Reciprocals of Diagonal Length Ratios in the Regular Polygon | journal=Forum Geometricorum | volume=6 | pages=97-101 | url=https://scispace.com/pdf/proof-by-picture-products-and-reciprocals-of-diagonal-length-1aian8mgp9.pdf }} {{Refend}} f6mvhwplgq8us2odbroo9xo8ycfbu54 2809832 2809825 2026-05-17T03:45:42Z Dc.samizdat 2856930 /* The 8-point regular polytopes */ 2809832 wikitext text/x-wiki {{align|center|David Brooks Christie}} {{align|center|dc@samizdat.org}} {{align|center|Draft in progress}} {{align|center|January 2026 - April 2026}} <blockquote>Steinbach discovered the formula for the ratios of diagonal to side in the regular polygons. Fontaine and Hurley extended this result, discovering a formula for the reciprocal of a regular polygon chord derived geometrically from the chord's star polygon. We observe that these findings in plane geometry apply more generally, to polytopes of any dimensionality. Fontaine and Hurley's geometric procedure for finding the reciprocals of the chords of a regular polygon from their star polygons also finds the rotational geodesics of any polytope of any dimensionality.</blockquote> == Introduction == Steinbach discovered the Diagonal Product Formula and the Golden Fields family of ratios of diagonal to side in the regular polygons. He showed how this family extends beyond the pentagon {5} with its well-known golden bisection proportional to 𝜙, finding that the heptagon {7} has an analogous trisection, the nonagon {9} has an analogous quadrasection, and the hendecagon {11} has an analogous pentasection, an extended family of golden proportions with quasiperiodic properties. Kappraff and Adamson extended these findings in plane geometry to a theory of Generalized Fibonacci Sequences, showing that the Golden Fields not only do not end with the hendecagon, they form an infinite number of periodic trajectories when operated on by the Mandelbrot operator. They found a relation between the edges of star polygons and dynamical systems in the state of chaos, revealing a connection between chaos theory, number, and rotations in Coxeter Euclidean geometry. Fontaine and Hurley examined Steinbach's finding that the length of each chord of a regular polygon is both the product of two chords and the sum of a set of smaller chords, so that in rotations to add is to multiply. They illustrated Steinbach's sets of additive chords lying parallel to each other in the plane (pointing in the same direction), and by applying Steinbach's formula more generally they found another summation relation of signed parallel chords (pointing in opposite directions) which relates each chord length to its reciprocal, and relates the summation to a distinct star polygon rotation. We examine these remarkable findings (which stem from study of the chords of humble regular polygons) in higher-dimensional spaces, specifically in the chords, polygons and rotations of the [[120-cell]], the largest four-dimensional regular convex polytope. == Visualizing the 120-cell == {| class="wikitable floatright" width="400" |style="vertical-align:top"|[[File:120-cell.gif|200px]]<br>Orthographic projection of the 600-point 120-cell <small><math>\{5,3,3\}</math></small> performing a [[W:SO(4)#Geometry of 4D rotations|simple rotation]].{{Sfn|Hise|2011|loc=File:120-cell.gif|ps=; "Created by Jason Hise with Maya and Macromedia Fireworks.

Therefore even though it is translucent, only its outer surface is visible. The complex interior parts of the 120-cell, all its inscribed 5-cells, 16-cells, 8-cells, 24-cells, 600-cells and its much larger inventory of polyhedra, are completely invisible in this view, as none of their edges are rendered at all. |style="vertical-align:top"|[[File:Ortho solid 016-uniform polychoron p33-t0.png|200px]]<br>Orthographic projection of the 600-point [[W:Great grand stellated 120-cell|great grand stellated 120-cell]] <small><math>\{\tfrac{5}{2},3,3\}</math></small>.{{Sfn|Ruen: Great grand stellated 120-cell|2007}} The 120-cell is its convex hull.

The 120-cell is the convex hull of a regular [[120-cell#Relationships among interior polytopes|compound of each of the 6 regular convex 4-polytopes]]. They are the [[5-cell|5-point (5-cell) 4-simplex]], the [[16-cell|8-point (16-cell) 4-orthoplex]], the [[W:Tesseract|16-point (8-cell) tesseract]], the [[24-cell|24-point (24-cell)]], the [[600-cell|120-point (600-cell)]], and the [[120-cell|600-point (120-cell)]]. The 120-cell is the convex hull of a compound of 120 disjoint regular 5-cells, of 75 disjoint 16-cells, of 25 disjoint 24-cells, and of 5 disjoint 600-cells. The 120-cell contains an even larger inventory of irregular polytopes, created by the intersection of multiple instances of these component regular 4-polytopes. Many are quite unexpected, because they do not occur as components of any regular polytope smaller than the 120-cell. As just one example among the [[120-cell#Concentric hulls|sections of the 120-cell]], there is an irregular 24-point polyhedron with 16 triangle faces and 4 nonagon {9} faces.{{Sfn|Moxness|}} Most renderings of the 120-cell, like the rotating projection here, only illustrate its outer surface, which is a honeycomb of face-bonded dodecahedral cells. Only the objects in its 3-dimensional surface are rendered, namely the 120 dodecahedra, their pentagon faces, and their edges. Although the 120-cell has chords of 30 distinct lengths, in this kind of simplified rendering only the 120-cell's own edges (its shortest chord) are shown. Its 29 interior chords, the edges of objects in the interior of the 120-cell, are not rendered, so interior objects are not visible at all. Visualizing the complete interior of the 600-vertex 120-cell in a single image is impractical because of its complexity. Only four 120-cell edges are incident at each vertex, but [[120-cell#Chords|600 chords (of all 30 lengths)]] are incident at ''each'' vertex. == Compounds in the 120-cell == The 8-point (16-cell), not the 5-point (5-cell), is the smallest building block; it compounds to every larger regular 4-polytope. The 5-point (5-cell) does compound to the 600-point (120-cell), but it does not fit into any smaller regular 4-polytope. The 8-point (16-cell) compounds by 2 in the 16-point (8-cell), and by 3 in the 24-point (24-cell). The 16-point (8-cell) compounds in the 24-point (24-cell) by 3 non-disjoint instances of itself, with each of the 24 vertices shared by two 16-point (8-cells). The 24-point (24-cell) compounds by 5 disjoint instances of itself in the 120-point (600-cell), and the 120-point (600-cell) compounds by 5 disjoint instances of itself in the 600-point (120-cell). The 24-point (24-cell) also compounds by <math>5^2</math> non-disjoint instances of itself in the 120-point (600-cell); it compounds in 5 disjoint instances of itself, 10 (not 5) different ways. Whichever set of 5 disjoint 24-point (24-cells) are assembled, the resulting 120-point (600-cell) contains 25 distinct 24-point (24-cells), not just 5 (or 10). This implies that 15 disjoint 8-point (16-cells) will construct a 120-point (600-cell), which will contain 75 distinct 8-point (16-cells). The 600-point (120-cell) is 5 disjoint 120-point (600-cells), just 2 different ways (not 5 or 10 ways), so it is 10 distinct 120-point (600-cells). This implies that the 8-point (16-cell) compounds by 3 times <math>5^2</math> (75) disjoint instances of itself in the 600-point (120-cell), which contains <math>3^2</math> times <math>5^2</math> (225) distinct instances of the 24-point (24-cell), and <math>3^3</math> times <math>5^2</math> (675) distinct instances of the 8-point (16-cell). These facts were discovered painstakingly by various researchers, and no one has found a general rule governing subsumption relations among regular polytopes. The reasons for some of their numeric incidence relations are far from obvious. [[W:Pieter Hendrik Schoute|Schoute]] was the first to see that the 120-point (600-cell) is a compound of 5 24-point (24-cells) ''10 different ways'', and after he saw it a hundred years lapsed until Denney, Hooker, Johnson, Robinson, Butler & Claiborne proved his result, and showed why.{{Sfn|Denney, Hooker, Johnson, Robinson, Butler & Claiborne|2020|loc=''The geometry of H4 polytopes''}} So much for the compounds of 16-cells. The 120-cell is also the convex hull of the compound of 120 disjoint regular 5-cells. That stellated compound (without its convex hull of 120-cell edges) is the [[w:Great_grand_stellated_120-cell|great grand stellated 120-cell]] illustrated above, the final regular [[W:Stellation|stellation]] of the 120-cell, and the only [[W:Schläfli-Hess polychoron|regular star 4-polytope]] to have the 120-cell for its convex hull. The edges of the great grand stellated 120-cell are <math>\phi^6</math> as long as those of its 120-cell [[W:List of polyhedral stellations#Stellation process|stellation core]] deep inside. The compound of 120 disjoint 5-point (5-cells) can be seen to be equivalent to the compound of 5 disjoint 120-point (600-cells), as follows. Beginning with a single 120-point (600-cell), expand each vertex into a regular 5-cell, by adding 4 new equidistant vertices, such that the 5 vertices form a regular 5-cell inscribed in the 3-sphere. The 120 5-cells are disjoint, and the 600 vertices form 5 disjoint 120-point (600-cells): a 120-cell. == Thirty distinguished distances == The 30 numbers listed in the table are all-important in Euclidean geometry. A case can be made on symmetry grounds that their squares are the 30 most important numbers between 0 and 4. The 30 rows of the table are the 30 distinct [[120-cell#Geodesic rectangles|chord lengths of the unit-radius 120-cell]], the largest regular convex 4-polytope. Since the 120-cell subsumes all smaller regular polytopes, its 30 chords are the complete chord set of all the regular polytopes that can be constructed in the first four dimensions of Euclidean space, except for regular polygons of more than 15 sides. {| class="wikitable" style="white-space:nowrap;text-align:center" !rowspan=2|<math>c_t</math> !rowspan=2|arc

regular polytopes == In 2-space we have the regular 8-point octagon, in 3-space the regular 8-point cube, and in 4-space the regular 8-point [[16-cell]]. A planar octagon with rigid edges of unit length has chords of length: :<math>r_1=1,r_2=\sqrt{2+\sqrt{2}} \approx 1.84776,r_3=1+\sqrt{2} \approx 2.41421,r_4=\sqrt{4 + \sqrt{8}} \approx 2.61313</math> The chord ratio <math>r_3=1+\sqrt{2}</math> is a geometrical proportion, the [[W:Silver ratio|silver ratio]]. Fontaine and Hurley's procedure for obtaining the reciprocal of a chord tells us that: :<math>r_3-r_1-r_1=1/r_3 \approx 0.41421</math> Note that <math>1/r_3=\sqrt{2}-1=r_3-2</math>. If we embed this planar octagon in 3-space, we can make it skew, repositioning its vertices so that each is one unit-edge length distant from three others instead of two others, at the vertices of a unit-edge cube with chords of length: :<math>r_1=1, r_2=\sqrt{2}, r_3=\sqrt{3}, r_4=\sqrt{2}</math> If we embed this cube in 4-space, we can skew it some more, repositioning its vertices so that each is one unit-edge length distant from six others instead of three others, at the vertices of a unit-edge 4-polytope with chords of length: :<math>r_1=1,r_2=1,r_3=1,r_4=\sqrt{2}</math> All of its chords except its long diameters are the same unit length as its edge. In fact they are its 24 edges, and it is a 16-cell of radius <small><math>1/\sqrt{2}</math></small>. [[File:octagon16cell.png|thumb|Orthogonal projection of a regular 16-cell to the [[16-cell#Projections|B<sub>4</sub> Coxeter plane]]. Only its edges are shown; its long diameter chords are not drawn. All 24 edges are the same length. Only the edges of the two disjoint squares lie parallel to the projection plane, in completely orthogonal central planes.]] The [[16-cell]] is the [[W:Regular convex 4-polytope|regular convex 4-polytope]] with [[W:Schläfli symbol|Schläfli symbol]] {3,3,4}. It has 8 vertices, 24 edges, 32 equilateral triangle faces, and 16 regular tetrahedron cells. It is the [[16-cell#Octahedral dipyramid|four-dimensional analogue of the octahedron]], and each of its four orthogonal central hyperplanes is an octahedron. The only planar regular polygons found in the 16-cell are face triangles and central plane squares, but the 16-cell also contains a skew regular octagon, its [[W:Petrie polygon|Petrie polygon]]. The chords of this regular octagon, which lies skew in 4-space, are those given above for the 16-cell, as opposed to those for the cube or the regular octagon in the plane. The 16-cell is a construct of 3 Petrie octagons which share the same 8 vertices but have disjoint sets of 8 edges each. The regular octad has higher symmetry in 4-space than it does in 2-space. The 16-cell is the 4-orthoplex, the simplest regular 4-polytope after the [[5-cell|4-simplex]]. All the larger regular 4-polytopes, including the 120-cell, are compounds of the 16-cell. The regular octagon exhibits this high symmetry only when embedded in 4-space at the vertices of the 16-cell. The 16-cell constitutes an [[W:Orthonormal basis|orthonormal basis]] for the choice of a 4-dimensional Cartesian reference frame, because its vertices define four orthogonal axes. The eight vertices of a unit-radius 16-cell are (±1, 0, 0, 0), (0, ±1, 0, 0), (0, 0, ±1, 0), (0, 0, 0, ±1). All vertices are connected by <small><math>\sqrt{2}</math></small> edges except opposite pairs. The vertex coordinates of the 16-cell form 6 central squares lying in 6 pairwise [[W:Orthogonal|orthogonal]] coordinate planes. Great squares in ''opposite'' planes that do not share an axis (e.g. in the ''xy'' and ''wz'' planes) are completely disjoint (they do not intersect at any vertices). These planes are [[W:Completely orthogonal|completely orthogonal]].{{Efn|name=Six orthogonal planes of the Cartesian basis}} Since this unit-radius coordinate system is convenient, let us derive the unit-radius 16-cell by skewing a unit-radius planar octagon, which has chords of length: :<math>r_1=\sqrt{2-\sqrt{2}} \approx 0.76537,r_2=\sqrt{2},r_3=\sqrt{2+\sqrt{2}} \approx 1.84776,r_4=2</math> We will need a planar octagon with rigid <math>r_2</math> chords, rather than one with rigid <math>r_1</math> edges. The octagon's <math>r_2</math> chords form two disjoint great squares, visible in the orthogonal projection, which we can reposition in 3-space to form a cube by making them parallel, and in 4-space to form a 16-cell by making them completely orthogonal. In the 16-cell the two completely orthogonal great squares formed by the <math>r_2</math> chords are both parallel and perpendicular to each other. A ''simple'' rotation of the 16-cell in ''one'' of those two central planes rotates that square like a wheel, while the other square does not move. The four vertices of the rotating square orbit on a great circle in the plane. The <math>r_1</math> chords of the 16-cell form a Petrie polygon which zig-zags back and forth between the two completely orthogonal <math>r_2</math> squares. The <math>r_3</math> chords of the 16-cell form a circular helix, visible as a skew {8/3} octagram in the orthogonal projection. A ''double'' rotation of the 16-cell, in ''both'' of the two completely orthogonal <math>r_2</math> square planes at once by the same angle, moves the eight vertices along the circular helix over the <math>r_3</math> chords. The circular helix is a [[w:Geodesic|geodesic]] great circle on the 3-sphere of a special kind: it does not lie in a single central plane, its circumference is <math>4 \pi</math>, and it occurs in either a left or right hand chiral form. [[W:Rotations in 4-dimensional Euclidean space|Rotations in 4-dimensional Euclidean space]] can be seen as the composition of two 2-dimensional rotations in completely orthogonal planes. The general rotation in 4-space is a double rotation in pairs of completely orthogonal planes. Two completely orthogonal planes are called invariant planes of the rotation when all points in the plane rotate on circles that remain in the plane, even as the whole plane tilts sideways (like a coin flipping) into another plane. The two completely orthogonal rotations of each plane (like a wheel, and like a coin flipping) are simultaneous but independent, in that they are not geometrically constrained to turn at the same rate. However, the most circular kind of rotation (as opposed to an elliptical double rotation of a rigid spherical object) occurs when the invariant planes do rotate through the same angle in the same time interval. Such equi-angled double rotations are called [[w:SO(4)#Isoclinic_rotations|isoclinic]], also [[w:William_Kingdon_Clifford|Clifford]] displacements. The 16-cell is the simplest possible frame in which to [[16-cell#Rotations|observe 4-dimensional rotations]] because its characteristic rotations feature a single pair of invariant rotation planes. In the 16-cell an isoclinic rotation by 90° in any pair of invariant completely orthogonal square central planes takes every square central plane to its completely orthogonal square central plane in a twisting displacement, as they tilt sideways 90° into each other's plane while rotating 90° internally. All the vertices move at once on the same circular helix geodesic, displaced 90° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. When the 90° isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 90°, but from the new orientation in a direction orthogonal to its first 90° displacement. After 360° of rotation each vertex reaches its antipodal position. The trajectory of each vertex over each 90° isoclinic rotational displacement is a one-eighth segment of its geodesic orbit. Its entire orbit traces a circular helix in 4-space over eight <math>r_3</math> chords, and also traces an ordinary great circle twice over the four <math>r_2</math> chords within one of the two moving invariant rotation planes. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once and returns to its original position, and the 16-cell returns to its original orientation. == Hypercubes == The long diameter of the unit-edge [[W:Hypercube|hypercube]] of dimension <small><math>n</math></small> is <small><math>\sqrt{n}</math></small>, so the unit-edge [[w:Tesseract|4-hypercube, the 16-point (8-cell) tesseract,]] has chords: :<math>r_1=\sqrt{1},r_2=\sqrt{2},r_3=\sqrt{3},r_4=\sqrt{4}</math> Uniquely in its 4-dimensional case, the hypercube's edge length equals its radius, like the hexagon. We call such polytopes ''radially equilateral'', because they can be constructed from equilateral triangles which meet at their center, each contributing two radii and an edge. The cuboctahedron and the 24-cell are also radially equilateral. The [[W:Tesseract|tesseract]] is the [[W:Regular convex 4-polytope|regular convex 4-polytope]] with [[W:Schläfli symbol|Schläfli symbol]] {4,3,3}. It has 16 vertices, 32 edges, 24 square faces, and 8 cube cells. It is the four-dimensional analogue of the cube. The tesseract is the [[W:Dual polytope|dual polytope]] of the 16-cell. They have the same Petrie polygon, the regular octagon, but the tesseract contains 2 disjoint instances and 4 distinct instances of the skew octagon. We can construct the tesseract by skewing two planar octagons. Because the tesseract is radially equilateral (unlike the 16-cell), we start with our original octagon of unit-edge length, rather than the octagon of edge length <small><math>\sqrt{2}</math></small> that we needed to build the unit-radius 16-cell. For our tesseract construction we skew each planar octagon into a cube, so we have a compound of two completely orthogonal cubes. Provided the planes were completely orthogonal in 4-space and we skewed them both the same way, the 16 vertices will be the vertices of a tesseract with half of its 32 edges missing. The 16-point tesseract is the convex hull of a compound of two 8-point 16-cells, in exact dimensional analogy to the way the 8-point cube is the convex hull of a [[W:Stellated octahedron|compound of two regular 4-point tetrahedra]]. The [[W:Demihypercube|demihypercubes]] occupy alternate vertices of the hypercubes. The diagonals of the square faces of the unit-radius tesseract are the <small><math>\sqrt{2}</math></small> edges of two unit-radius 16-cells, which are also the edges of the square central planes. Because the tesseract contains two 16-cells in alternate positions it has two sets of 6 orthogonal square central planes. Two angles are required to specify the relationship between two planes in 4-space. Pairs of planes within each 16-cell are 90° apart in one angle, and either 0° or 90° apart in the other angle. They are 90° apart in both angles if and only if they are completely orthogonal planes, 90° apart by isoclinic rotation, with no vertices in common and their corresponding vertices 180° apart. Otherwise they are 0° apart in one of the angles, 90° apart by simple rotation with their corresponding vertices 90° apart, and they intersect in one axis and lie in a common 3-dimensional hyperplane.{{Efn|A double rotation in which one of the two angles of rotation is 0°, so that one of the completely orthogonal invariant planes does not rotate, is called a simple rotation. Ordinary rotations observed in a 3-dimensional space are simple rotations.}} A pair of square central planes from alternate 16-cells are 60° apart by isoclinic rotation, with their corresponding vertices 120° apart. The planes are not orthogonal or parallel, so they intersect in a line somewhere, but they have no vertices in common, they have no 3-dimensional hyperplane in common, and they cannot reach each other by simple rotation. Such pairs of objects are called [[W:Clifford parallel|Clifford parallel]] because all their corresponding pairs of vertices are the same distance apart, although they are not parallel in the usual sense, because they have a common center. Not only the alternate 16-cells' corresponding square central planes, but also the 16-cells themselves, are Clifford parallel objects. We can rotate the tesseract isoclinically the way we rotated the 16-cell, by 90° in two completely orthogonal invariant square central planes, with the same effect on both alternate 16-cells. In the course of a 720° isoclinic rotation in invariant square central planes each vertex departs from all 8 vertex positions of its 16-cell just once and returns to its original position, but it does not visit the vertex positions of the other 16-cell. The skew octagon geodesic orbits of the 16 vertices lie on two disjoint octagram circular helixes of the same chirality, which are Clifford parallel objects that form a circular double helix. == The 24-cell == In 2-space we have the radially equilateral 6-point hexagon. In 3-space we have the radially equilateral 12-point cuboctahedron, with 4 hexagonal central planes. In 4-space we have the radially equilateral 24-point 24-cell, with 4 cuboctahedral central hyperplanes and 16 hexagonal central planes. Great hexagons are a rounder choice than great squares for the invariant rotation planes in which to rotate a 4-polytope isoclinically. The complete hexagonal isoclinic revolution requires 720° like the square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 90° each. ... == The 600-cell == ... == Finally the 120-cell == ... == Conclusions == Fontaine and Hurley's discovery is more than a formula for the reciprocal of a regular ''n''-polygon diagonal. It also yields the discrete sequence of isocline chords of the distinct isoclinic rotation characteristic of a ''d''-dimensional regular polytope. The characteristic rotational chord sequence of the ''d''-polytope can be represented geometrically in two dimensions on a distinct star polygon, but it lies on a geodesic circle through ''d''-dimensional space. Fontaine and Hurley discovered the geodesic topology of polytopes generally. Their procedure will reveal the geodesics of arbitrary non-uniform polytopes, since it can be applied to a polytope of any dimensionality and irregularity, by first fitting the polytope to the smallest regular polygon whose chords include its chords. Fontaine and Hurley's discovery of a chordal formula for isoclinic rotations closes the circuit on Kappraff and Adamson's discovery of a rotational connection between dynamical systems, Steinbach's golden fields, and Coxeter's Euclidean geometry of ''n'' dimensions. Application of the Fontaine and Hurley procedure in higher-dimensional spaces demonstrates why the connection exists: because polytope sequences generally, from Steinbach's golden polygon chord sequences, to chord sequences in isoclinic rotation helixes, to subsumption relations in the sequence of regular 4-polytopes, arise as expressions of the reflections and rotations of distinct Coxeter symmetry groups, when those various groups interact. == Appendix: Sequence of regular 4-polytopes == {{Regular convex 4-polytopes|wiki=W:|columns=7}} == Notes == {{Notelist}} == Citations == {{Reflist}} == References == {{Refbegin}} * {{Cite journal | last=Steinbach | first=Peter | year=1997 | title=Golden fields: A case for the Heptagon | journal=Mathematics Magazine | volume=70 | issue=Feb 1997 | pages=22–31 | doi=10.1080/0025570X.1997.11996494 | jstor=2691048 | ref={{SfnRef|Steinbach|1997}} }} * {{Cite journal | last=Steinbach | first=Peter | year=2000 | title=Sections Beyond Golden| journal=Bridges: Mathematical Connections in Art, Music and Science | issue=2000 | pages=35-44 | url=https://archive.bridgesmathart.org/2000/bridges2000-35.pdf | ref={{SfnRef|Steinbach|2000}}}} * {{Cite journal | last1=Kappraff | first1=Jay | last2=Jablan | first2=Slavik | last3=Adamson | first3=Gary | last4=Sazdanovich | first4=Radmila | year=2004 | title=Golden Fields, Generalized Fibonacci Sequences, and Chaotic Matrices | journal=Forma | volume=19 | pages=367-387 | url=https://archive.bridgesmathart.org/2005/bridges2005-369.pdf | ref={{SfnRef|Kappraff, Jablan, Adamson & Sazdanovich|2004}} }} * {{Cite journal | last1=Kappraff | first1=Jay | last2=Adamson | first2=Gary | year=2004 | title=Polygons and Chaos | journal=Dynamical Systems and Geometric Theories | url=https://archive.bridgesmathart.org/2001/bridges2001-67.pdf | ref={{SfnRef|Kappraff & Adamson|2004}} }} * {{Cite journal | last1=Fontaine | first1=Anne | last2=Hurley | first2=Susan | year=2006 | title=Proof by Picture: Products and Reciprocals of Diagonal Length Ratios in the Regular Polygon | journal=Forum Geometricorum | volume=6 | pages=97-101 | url=https://scispace.com/pdf/proof-by-picture-products-and-reciprocals-of-diagonal-length-1aian8mgp9.pdf }} {{Refend}} hg0ij8c6rwk1l3d3ylfmc1d6uxz06y7 2809834 2809832 2026-05-17T03:47:38Z Dc.samizdat 2856930 /* The 8-point regular polytopes */ 2809834 wikitext text/x-wiki {{align|center|David Brooks Christie}} {{align|center|dc@samizdat.org}} {{align|center|Draft in progress}} {{align|center|January 2026 - April 2026}} <blockquote>Steinbach discovered the formula for the ratios of diagonal to side in the regular polygons. Fontaine and Hurley extended this result, discovering a formula for the reciprocal of a regular polygon chord derived geometrically from the chord's star polygon. We observe that these findings in plane geometry apply more generally, to polytopes of any dimensionality. Fontaine and Hurley's geometric procedure for finding the reciprocals of the chords of a regular polygon from their star polygons also finds the rotational geodesics of any polytope of any dimensionality.</blockquote> == Introduction == Steinbach discovered the Diagonal Product Formula and the Golden Fields family of ratios of diagonal to side in the regular polygons. He showed how this family extends beyond the pentagon {5} with its well-known golden bisection proportional to 𝜙, finding that the heptagon {7} has an analogous trisection, the nonagon {9} has an analogous quadrasection, and the hendecagon {11} has an analogous pentasection, an extended family of golden proportions with quasiperiodic properties. Kappraff and Adamson extended these findings in plane geometry to a theory of Generalized Fibonacci Sequences, showing that the Golden Fields not only do not end with the hendecagon, they form an infinite number of periodic trajectories when operated on by the Mandelbrot operator. They found a relation between the edges of star polygons and dynamical systems in the state of chaos, revealing a connection between chaos theory, number, and rotations in Coxeter Euclidean geometry. Fontaine and Hurley examined Steinbach's finding that the length of each chord of a regular polygon is both the product of two chords and the sum of a set of smaller chords, so that in rotations to add is to multiply. They illustrated Steinbach's sets of additive chords lying parallel to each other in the plane (pointing in the same direction), and by applying Steinbach's formula more generally they found another summation relation of signed parallel chords (pointing in opposite directions) which relates each chord length to its reciprocal, and relates the summation to a distinct star polygon rotation. We examine these remarkable findings (which stem from study of the chords of humble regular polygons) in higher-dimensional spaces, specifically in the chords, polygons and rotations of the [[120-cell]], the largest four-dimensional regular convex polytope. == Visualizing the 120-cell == {| class="wikitable floatright" width="400" |style="vertical-align:top"|[[File:120-cell.gif|200px]]<br>Orthographic projection of the 600-point 120-cell <small><math>\{5,3,3\}</math></small> performing a [[W:SO(4)#Geometry of 4D rotations|simple rotation]].{{Sfn|Hise|2011|loc=File:120-cell.gif|ps=; "Created by Jason Hise with Maya and Macromedia Fireworks.

Therefore even though it is translucent, only its outer surface is visible. The complex interior parts of the 120-cell, all its inscribed 5-cells, 16-cells, 8-cells, 24-cells, 600-cells and its much larger inventory of polyhedra, are completely invisible in this view, as none of their edges are rendered at all. |style="vertical-align:top"|[[File:Ortho solid 016-uniform polychoron p33-t0.png|200px]]<br>Orthographic projection of the 600-point [[W:Great grand stellated 120-cell|great grand stellated 120-cell]] <small><math>\{\tfrac{5}{2},3,3\}</math></small>.{{Sfn|Ruen: Great grand stellated 120-cell|2007}} The 120-cell is its convex hull.

The 120-cell is the convex hull of a regular [[120-cell#Relationships among interior polytopes|compound of each of the 6 regular convex 4-polytopes]]. They are the [[5-cell|5-point (5-cell) 4-simplex]], the [[16-cell|8-point (16-cell) 4-orthoplex]], the [[W:Tesseract|16-point (8-cell) tesseract]], the [[24-cell|24-point (24-cell)]], the [[600-cell|120-point (600-cell)]], and the [[120-cell|600-point (120-cell)]]. The 120-cell is the convex hull of a compound of 120 disjoint regular 5-cells, of 75 disjoint 16-cells, of 25 disjoint 24-cells, and of 5 disjoint 600-cells. The 120-cell contains an even larger inventory of irregular polytopes, created by the intersection of multiple instances of these component regular 4-polytopes. Many are quite unexpected, because they do not occur as components of any regular polytope smaller than the 120-cell. As just one example among the [[120-cell#Concentric hulls|sections of the 120-cell]], there is an irregular 24-point polyhedron with 16 triangle faces and 4 nonagon {9} faces.{{Sfn|Moxness|}} Most renderings of the 120-cell, like the rotating projection here, only illustrate its outer surface, which is a honeycomb of face-bonded dodecahedral cells. Only the objects in its 3-dimensional surface are rendered, namely the 120 dodecahedra, their pentagon faces, and their edges. Although the 120-cell has chords of 30 distinct lengths, in this kind of simplified rendering only the 120-cell's own edges (its shortest chord) are shown. Its 29 interior chords, the edges of objects in the interior of the 120-cell, are not rendered, so interior objects are not visible at all. Visualizing the complete interior of the 600-vertex 120-cell in a single image is impractical because of its complexity. Only four 120-cell edges are incident at each vertex, but [[120-cell#Chords|600 chords (of all 30 lengths)]] are incident at ''each'' vertex. == Compounds in the 120-cell == The 8-point (16-cell), not the 5-point (5-cell), is the smallest building block; it compounds to every larger regular 4-polytope. The 5-point (5-cell) does compound to the 600-point (120-cell), but it does not fit into any smaller regular 4-polytope. The 8-point (16-cell) compounds by 2 in the 16-point (8-cell), and by 3 in the 24-point (24-cell). The 16-point (8-cell) compounds in the 24-point (24-cell) by 3 non-disjoint instances of itself, with each of the 24 vertices shared by two 16-point (8-cells). The 24-point (24-cell) compounds by 5 disjoint instances of itself in the 120-point (600-cell), and the 120-point (600-cell) compounds by 5 disjoint instances of itself in the 600-point (120-cell). The 24-point (24-cell) also compounds by <math>5^2</math> non-disjoint instances of itself in the 120-point (600-cell); it compounds in 5 disjoint instances of itself, 10 (not 5) different ways. Whichever set of 5 disjoint 24-point (24-cells) are assembled, the resulting 120-point (600-cell) contains 25 distinct 24-point (24-cells), not just 5 (or 10). This implies that 15 disjoint 8-point (16-cells) will construct a 120-point (600-cell), which will contain 75 distinct 8-point (16-cells). The 600-point (120-cell) is 5 disjoint 120-point (600-cells), just 2 different ways (not 5 or 10 ways), so it is 10 distinct 120-point (600-cells). This implies that the 8-point (16-cell) compounds by 3 times <math>5^2</math> (75) disjoint instances of itself in the 600-point (120-cell), which contains <math>3^2</math> times <math>5^2</math> (225) distinct instances of the 24-point (24-cell), and <math>3^3</math> times <math>5^2</math> (675) distinct instances of the 8-point (16-cell). These facts were discovered painstakingly by various researchers, and no one has found a general rule governing subsumption relations among regular polytopes. The reasons for some of their numeric incidence relations are far from obvious. [[W:Pieter Hendrik Schoute|Schoute]] was the first to see that the 120-point (600-cell) is a compound of 5 24-point (24-cells) ''10 different ways'', and after he saw it a hundred years lapsed until Denney, Hooker, Johnson, Robinson, Butler & Claiborne proved his result, and showed why.{{Sfn|Denney, Hooker, Johnson, Robinson, Butler & Claiborne|2020|loc=''The geometry of H4 polytopes''}} So much for the compounds of 16-cells. The 120-cell is also the convex hull of the compound of 120 disjoint regular 5-cells. That stellated compound (without its convex hull of 120-cell edges) is the [[w:Great_grand_stellated_120-cell|great grand stellated 120-cell]] illustrated above, the final regular [[W:Stellation|stellation]] of the 120-cell, and the only [[W:Schläfli-Hess polychoron|regular star 4-polytope]] to have the 120-cell for its convex hull. The edges of the great grand stellated 120-cell are <math>\phi^6</math> as long as those of its 120-cell [[W:List of polyhedral stellations#Stellation process|stellation core]] deep inside. The compound of 120 disjoint 5-point (5-cells) can be seen to be equivalent to the compound of 5 disjoint 120-point (600-cells), as follows. Beginning with a single 120-point (600-cell), expand each vertex into a regular 5-cell, by adding 4 new equidistant vertices, such that the 5 vertices form a regular 5-cell inscribed in the 3-sphere. The 120 5-cells are disjoint, and the 600 vertices form 5 disjoint 120-point (600-cells): a 120-cell. == Thirty distinguished distances == The 30 numbers listed in the table are all-important in Euclidean geometry. A case can be made on symmetry grounds that their squares are the 30 most important numbers between 0 and 4. The 30 rows of the table are the 30 distinct [[120-cell#Geodesic rectangles|chord lengths of the unit-radius 120-cell]], the largest regular convex 4-polytope. Since the 120-cell subsumes all smaller regular polytopes, its 30 chords are the complete chord set of all the regular polytopes that can be constructed in the first four dimensions of Euclidean space, except for regular polygons of more than 15 sides. {| class="wikitable" style="white-space:nowrap;text-align:center" !rowspan=2|<math>c_t</math> !rowspan=2|arc

regular polytopes == In 2-space we have the regular 8-point octagon, in 3-space the regular 8-point cube, and in 4-space the regular 8-point [[16-cell]]. A planar octagon with rigid edges of unit length has chords of length: :<math>r_1=1,r_2=\sqrt{2+\sqrt{2}} \approx 1.84776,r_3=1+\sqrt{2} \approx 2.41421,r_4=\sqrt{4 + \sqrt{8}} \approx 2.61313</math> The chord ratio <math>r_3=1+\sqrt{2}</math> is a geometrical proportion, the [[W:Silver ratio|silver ratio]]. Fontaine and Hurley's procedure for obtaining the reciprocal of a chord tells us that: :<math>r_3-r_1-r_1=1/r_3 \approx 0.41421</math> Note that <math>1/r_3=\sqrt{2}-1=r_3-2</math>. If we embed this planar octagon in 3-space, we can make it skew, repositioning its vertices so that each is one unit-edge length distant from three others instead of two others, at the vertices of a unit-edge cube with chords of length: :<math>r_1=1, r_2=\sqrt{2}, r_3=\sqrt{3}, r_4=\sqrt{2}</math> If we embed this cube in 4-space, we can skew it some more, repositioning its vertices so that each is one unit-edge length distant from six others instead of three others, at the vertices of a unit-edge 4-polytope with chords of length: :<math>r_1=1,r_2=1,r_3=1,r_4=\sqrt{2}</math> All of its chords except its long diameters are the same unit length as its edge. In fact they are its 24 edges, and it is a 16-cell of radius <small><math>1/\sqrt{2}</math></small>. [[File:octagon16cell.png|thumb|Orthogonal projection of a regular 16-cell to the [[16-cell#Projections|B<sub>4</sub> Coxeter plane]]. Only its edges are shown; its long diameter chords are not drawn. All 24 edges are the same length. Only the edges of the two disjoint squares lie parallel to the projection plane, in completely orthogonal central planes.]] The [[16-cell]] is the [[W:Regular convex 4-polytope|regular convex 4-polytope]] with [[W:Schläfli symbol|Schläfli symbol]] {3,3,4}. It has 8 vertices, 24 edges, 32 equilateral triangle faces, and 16 regular tetrahedron cells. It is the [[16-cell#Octahedral dipyramid|four-dimensional analogue of the octahedron]], and each of its four orthogonal central hyperplanes is an octahedron. The only planar regular polygons found in the 16-cell are face triangles and central plane squares, but the 16-cell also contains a skew regular octagon, its [[W:Petrie polygon|Petrie polygon]]. The chords of this regular octagon, which lies skew in 4-space, are those given above for the 16-cell, as opposed to those for the cube or the regular octagon in the plane. The 16-cell is a construct of 3 Petrie octagons which share the same 8 vertices but have disjoint sets of 8 edges each. The regular octad has higher symmetry in 4-space than it does in 2-space. The 16-cell is the 4-orthoplex, the simplest regular 4-polytope after the [[5-cell|4-simplex]]. All the larger regular 4-polytopes, including the 120-cell, are compounds of the 16-cell. The regular octagon exhibits this high symmetry only when embedded in 4-space at the vertices of the 16-cell. The 16-cell constitutes an [[W:Orthonormal basis|orthonormal basis]] for the choice of a 4-dimensional Cartesian reference frame, because its vertices define four orthogonal axes. The eight vertices of a unit-radius 16-cell are (±1, 0, 0, 0), (0, ±1, 0, 0), (0, 0, ±1, 0), (0, 0, 0, ±1). All vertices are connected by <small><math>\sqrt{2}</math></small> edges except opposite pairs. The vertex coordinates of the 16-cell form 6 central squares lying in 6 pairwise [[W:Orthogonal|orthogonal]] coordinate planes. Great squares in ''opposite'' planes that do not share an axis (e.g. in the ''xy'' and ''wz'' planes) are completely disjoint (they do not intersect at any vertices). These planes are [[W:Completely orthogonal|completely orthogonal]].{{Efn|name=Six orthogonal planes of the Cartesian basis}} Since this unit-radius coordinate system is convenient, let us derive the unit-radius 16-cell by skewing a unit-radius planar octagon, which has chords of length: :<math>r_1=\sqrt{2-\sqrt{2}} \approx 0.76537,r_2=\sqrt{2},r_3=\sqrt{2+\sqrt{2}} \approx 1.84776,r_4=2</math> We will need a planar octagon with rigid <math>r_2</math> chords, rather than one with rigid <math>r_1</math> edges. The octagon's <math>r_2</math> chords form two disjoint great squares, visible in the orthogonal projection, which we can reposition in 3-space to form a cube by making them parallel, and in 4-space to form a 16-cell by making them completely orthogonal. In the 16-cell the two completely orthogonal great squares formed by the <math>r_2</math> chords are both parallel and perpendicular to each other. A ''simple'' rotation of the 16-cell in ''one'' of those two central planes rotates that square like a wheel, while the other square does not move. The four vertices of the rotating square orbit on a great circle in the plane. The <math>r_1</math> chords of the 16-cell form a Petrie polygon which zig-zags back and forth between the two completely orthogonal <math>r_2</math> squares. The <math>r_3</math> chords of the 16-cell form a circular helix, visible as a skew {8/3} octagram in the orthogonal projection. A ''double'' rotation of the 16-cell, in ''both'' of the two completely orthogonal <math>r_2</math> square planes at once by the same angle, moves the eight vertices along the circular helix over the <math>r_3</math> chords. The circular helix is a [[w:Geodesic|geodesic]] great circle on the 3-sphere of a special kind: it does not lie in a central plane, its circumference is <math>4 \pi</math>, and it occurs in either a left or right hand chiral form. [[W:Rotations in 4-dimensional Euclidean space|Rotations in 4-dimensional Euclidean space]] can be seen as the composition of two 2-dimensional rotations in completely orthogonal planes. The general rotation in 4-space is a double rotation in pairs of completely orthogonal planes. Two completely orthogonal planes are called invariant planes of the rotation when all points in the plane rotate on circles that remain in the plane, even as the whole plane tilts sideways (like a coin flipping) into another plane. The two completely orthogonal rotations of each plane (like a wheel, and like a coin flipping) are simultaneous but independent, in that they are not geometrically constrained to turn at the same rate. However, the most circular kind of rotation (as opposed to an elliptical double rotation of a rigid spherical object) occurs when the invariant planes do rotate through the same angle in the same time interval. Such equi-angled double rotations are called [[w:SO(4)#Isoclinic_rotations|isoclinic]], also [[w:William_Kingdon_Clifford|Clifford]] displacements. The 16-cell is the simplest possible frame in which to [[16-cell#Rotations|observe 4-dimensional rotations]] because its characteristic rotations feature a single pair of invariant rotation planes. In the 16-cell an isoclinic rotation by 90° in any pair of invariant completely orthogonal square central planes takes every square central plane to its completely orthogonal square central plane in a twisting displacement, as they tilt sideways 90° into each other's plane while rotating 90° internally. All the vertices move at once on the same circular helix geodesic, displaced 90° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. When the 90° isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 90°, but from the new orientation in a direction orthogonal to its first 90° displacement. After 360° of rotation each vertex reaches its antipodal position. The trajectory of each vertex over each 90° isoclinic rotational displacement is a one-eighth segment of its geodesic orbit. Its entire orbit traces a circular helix in 4-space over eight <math>r_3</math> chords, and also traces an ordinary great circle twice over the four <math>r_2</math> chords within one of the two moving invariant rotation planes. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once and returns to its original position, and the 16-cell returns to its original orientation. == Hypercubes == The long diameter of the unit-edge [[W:Hypercube|hypercube]] of dimension <small><math>n</math></small> is <small><math>\sqrt{n}</math></small>, so the unit-edge [[w:Tesseract|4-hypercube, the 16-point (8-cell) tesseract,]] has chords: :<math>r_1=\sqrt{1},r_2=\sqrt{2},r_3=\sqrt{3},r_4=\sqrt{4}</math> Uniquely in its 4-dimensional case, the hypercube's edge length equals its radius, like the hexagon. We call such polytopes ''radially equilateral'', because they can be constructed from equilateral triangles which meet at their center, each contributing two radii and an edge. The cuboctahedron and the 24-cell are also radially equilateral. The [[W:Tesseract|tesseract]] is the [[W:Regular convex 4-polytope|regular convex 4-polytope]] with [[W:Schläfli symbol|Schläfli symbol]] {4,3,3}. It has 16 vertices, 32 edges, 24 square faces, and 8 cube cells. It is the four-dimensional analogue of the cube. The tesseract is the [[W:Dual polytope|dual polytope]] of the 16-cell. They have the same Petrie polygon, the regular octagon, but the tesseract contains 2 disjoint instances and 4 distinct instances of the skew octagon. We can construct the tesseract by skewing two planar octagons. Because the tesseract is radially equilateral (unlike the 16-cell), we start with our original octagon of unit-edge length, rather than the octagon of edge length <small><math>\sqrt{2}</math></small> that we needed to build the unit-radius 16-cell. For our tesseract construction we skew each planar octagon into a cube, so we have a compound of two completely orthogonal cubes. Provided the planes were completely orthogonal in 4-space and we skewed them both the same way, the 16 vertices will be the vertices of a tesseract with half of its 32 edges missing. The 16-point tesseract is the convex hull of a compound of two 8-point 16-cells, in exact dimensional analogy to the way the 8-point cube is the convex hull of a [[W:Stellated octahedron|compound of two regular 4-point tetrahedra]]. The [[W:Demihypercube|demihypercubes]] occupy alternate vertices of the hypercubes. The diagonals of the square faces of the unit-radius tesseract are the <small><math>\sqrt{2}</math></small> edges of two unit-radius 16-cells, which are also the edges of the square central planes. Because the tesseract contains two 16-cells in alternate positions it has two sets of 6 orthogonal square central planes. Two angles are required to specify the relationship between two planes in 4-space. Pairs of planes within each 16-cell are 90° apart in one angle, and either 0° or 90° apart in the other angle. They are 90° apart in both angles if and only if they are completely orthogonal planes, 90° apart by isoclinic rotation, with no vertices in common and their corresponding vertices 180° apart. Otherwise they are 0° apart in one of the angles, 90° apart by simple rotation with their corresponding vertices 90° apart, and they intersect in one axis and lie in a common 3-dimensional hyperplane.{{Efn|A double rotation in which one of the two angles of rotation is 0°, so that one of the completely orthogonal invariant planes does not rotate, is called a simple rotation. Ordinary rotations observed in a 3-dimensional space are simple rotations.}} A pair of square central planes from alternate 16-cells are 60° apart by isoclinic rotation, with their corresponding vertices 120° apart. The planes are not orthogonal or parallel, so they intersect in a line somewhere, but they have no vertices in common, they have no 3-dimensional hyperplane in common, and they cannot reach each other by simple rotation. Such pairs of objects are called [[W:Clifford parallel|Clifford parallel]] because all their corresponding pairs of vertices are the same distance apart, although they are not parallel in the usual sense, because they have a common center. Not only the alternate 16-cells' corresponding square central planes, but also the 16-cells themselves, are Clifford parallel objects. We can rotate the tesseract isoclinically the way we rotated the 16-cell, by 90° in two completely orthogonal invariant square central planes, with the same effect on both alternate 16-cells. In the course of a 720° isoclinic rotation in invariant square central planes each vertex departs from all 8 vertex positions of its 16-cell just once and returns to its original position, but it does not visit the vertex positions of the other 16-cell. The skew octagon geodesic orbits of the 16 vertices lie on two disjoint octagram circular helixes of the same chirality, which are Clifford parallel objects that form a circular double helix. == The 24-cell == In 2-space we have the radially equilateral 6-point hexagon. In 3-space we have the radially equilateral 12-point cuboctahedron, with 4 hexagonal central planes. In 4-space we have the radially equilateral 24-point 24-cell, with 4 cuboctahedral central hyperplanes and 16 hexagonal central planes. Great hexagons are a rounder choice than great squares for the invariant rotation planes in which to rotate a 4-polytope isoclinically. The complete hexagonal isoclinic revolution requires 720° like the square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 90° each. ... == The 600-cell == ... == Finally the 120-cell == ... == Conclusions == Fontaine and Hurley's discovery is more than a formula for the reciprocal of a regular ''n''-polygon diagonal. It also yields the discrete sequence of isocline chords of the distinct isoclinic rotation characteristic of a ''d''-dimensional regular polytope. The characteristic rotational chord sequence of the ''d''-polytope can be represented geometrically in two dimensions on a distinct star polygon, but it lies on a geodesic circle through ''d''-dimensional space. Fontaine and Hurley discovered the geodesic topology of polytopes generally. Their procedure will reveal the geodesics of arbitrary non-uniform polytopes, since it can be applied to a polytope of any dimensionality and irregularity, by first fitting the polytope to the smallest regular polygon whose chords include its chords. Fontaine and Hurley's discovery of a chordal formula for isoclinic rotations closes the circuit on Kappraff and Adamson's discovery of a rotational connection between dynamical systems, Steinbach's golden fields, and Coxeter's Euclidean geometry of ''n'' dimensions. Application of the Fontaine and Hurley procedure in higher-dimensional spaces demonstrates why the connection exists: because polytope sequences generally, from Steinbach's golden polygon chord sequences, to chord sequences in isoclinic rotation helixes, to subsumption relations in the sequence of regular 4-polytopes, arise as expressions of the reflections and rotations of distinct Coxeter symmetry groups, when those various groups interact. == Appendix: Sequence of regular 4-polytopes == {{Regular convex 4-polytopes|wiki=W:|columns=7}} == Notes == {{Notelist}} == Citations == {{Reflist}} == References == {{Refbegin}} * {{Cite journal | last=Steinbach | first=Peter | year=1997 | title=Golden fields: A case for the Heptagon | journal=Mathematics Magazine | volume=70 | issue=Feb 1997 | pages=22–31 | doi=10.1080/0025570X.1997.11996494 | jstor=2691048 | ref={{SfnRef|Steinbach|1997}} }} * {{Cite journal | last=Steinbach | first=Peter | year=2000 | title=Sections Beyond Golden| journal=Bridges: Mathematical Connections in Art, Music and Science | issue=2000 | pages=35-44 | url=https://archive.bridgesmathart.org/2000/bridges2000-35.pdf | ref={{SfnRef|Steinbach|2000}}}} * {{Cite journal | last1=Kappraff | first1=Jay | last2=Jablan | first2=Slavik | last3=Adamson | first3=Gary | last4=Sazdanovich | first4=Radmila | year=2004 | title=Golden Fields, Generalized Fibonacci Sequences, and Chaotic Matrices | journal=Forma | volume=19 | pages=367-387 | url=https://archive.bridgesmathart.org/2005/bridges2005-369.pdf | ref={{SfnRef|Kappraff, Jablan, Adamson & Sazdanovich|2004}} }} * {{Cite journal | last1=Kappraff | first1=Jay | last2=Adamson | first2=Gary | year=2004 | title=Polygons and Chaos | journal=Dynamical Systems and Geometric Theories | url=https://archive.bridgesmathart.org/2001/bridges2001-67.pdf | ref={{SfnRef|Kappraff & Adamson|2004}} }} * {{Cite journal | last1=Fontaine | first1=Anne | last2=Hurley | first2=Susan | year=2006 | title=Proof by Picture: Products and Reciprocals of Diagonal Length Ratios in the Regular Polygon | journal=Forum Geometricorum | volume=6 | pages=97-101 | url=https://scispace.com/pdf/proof-by-picture-products-and-reciprocals-of-diagonal-length-1aian8mgp9.pdf }} {{Refend}} oexuz3nl4vrh6sagtdbipvvxcenhml7 Media Literacy and You 0 327555 2809771 2809432 2026-05-16T22:33:00Z DavidMCEddy 218607 cite: Wikipedia: most democratic force ... 2809771 wikitext text/x-wiki [[File:Pharoah - James VI and I - Trump.png|thumb|Religious and media leaders from the time of the Pharaohs convinced common folk to give increasing shares of what they produced to elites.]] :''This book uses dates in [[:w:ISO 8601|ISO 8601]], YYYY-MM-DD, when convenient.'' == Invitation to edit this book == You, dear reader, are invited to contribute questions, ideas and citations to support or refute claims made in this book possibly adding chapters.

Passive media literacy, which is helping individuals understand the importance of looking for information that might contradict one's preconceptions (including suggestions on how to find alternative source of information). This suggests a need for ''disconfirmation bias'' to overcome the [[w:confirmation bias|confirmation bias]] that is a problematic feature of human psychology exploited by the major media, including for-profit social media, to please those who control most of their money. :2. Proactive media literacy, which is helping individuals learn how to engage others in open, non-threatening and supportive conversations to share concerns, compare sources of information, and build relationships in which different humans can collaborate productively on areas on of common concern while agreeing to disagree agreeable where they differ. :3. Active media literacy, by which students of media literacy educate others on media literacy. If each one teaches two<ref>"[[:w:Each one teach one|Each one teach one]]" is an African-American proverb from the time of legalized slavery. However, if each one teaches only one, the growth in literacy will only be linear. Having "each one teaching two", on average, unleashes the power of doubling and [[:w:exponential growth|exponential growth]], which has the potential of educating the entirety of humanity in a reasonable period of time -- namely after 33 doublings starting from one.</ref> in a certain period of time, that time period becomes a [[:w:Doubling time|doubling time]].

Much of this book is a [[w:Monograph|research monograph]] summarizing research that seems to have been underreported by the major media to avoid offending people who control most of the money for the media. These research results seem to be central to major political divisions. Each chapter ends in exercises to help the reader practice media literacy skills and have fun doing it. Remember: :''I am entitled to my [[Wiktionary:cockamamie|cockamamie]] ideas, and you are entitled to yours.'' Humor is important but must be offered in a way that does not offend others. If others are offended, they may be less interested in dialogue. The term "cockamamie" is used here, hoping that this style of [[w:Self-deprecation|self-deprecation]] might be more inviting for dialogue. ''Never say, "You're wrong, and I'm right!" instead, ask, "May I offer a contrary perspective?" Or "May I share with you another view that I've heard?" '' Much of the information in this book seems to have been largely overlooked and perhaps suppressed, apparently because it would increase the cost of producing news, some of which would clearly offend people who control much of the money for the media; see the brief discussion of conflicts of interest by the major media in the next "Key claims" section. ==Key claims== * ''Primary drivers of every major conflict include differences between the media that the different parties find credible''. :-- This works, because everything we think we know is coded in systems of connections between neurons in our brains.

His response was to clandestinely provoke an attack on US naval vessels in the Gulf of Tonkin, which he could then denounce as "unprovoked". During a dark and stormy night 1964-08-04 the [[w:USS Maddox (DD-731)|USS ''Maddox'']] and [[w:USS Turner Joy|''Turner Joy'']] spent a couple of hours "defending themselves" against radar snow, then [[w:Gulf of Tonkin incident|reported that they had sunk two attacking North Vietnamese torpedo boats]]; subsequent investigations found no evidence of the reported attacks. That incident was used to justify the [[w:Gulf of Tonkin Resolution|Gulf of Tonkin Resolution]], with only two dissenting votes in the US Congress: Those two dissenters were defeated in their next reelection campaigns, illustrating the point that the major media create the environment in which many politicians cannot get elected without betraying the nation. === The value of noncommercial news outlets === Some of the problems with the media and their contributions to increasing political polarization and violence are documented in the research summary on "[[Information is a public good: Designing experiments to improve government]]" and in the podcast series available on Wikiversity under "[[:Category:Media reform to improve democracy]]" with leading experts discussing their recommendations. One of the most compelling of the references discussed in that podcast series is Usher and Kim-Leffingwell (2022), who tallied all the federal prosecutions for political corruption in each of the 94 [[w:United States federal judicial district|US federal court district]]s between 2003 and 2019. During that period, the number of journalists in the US fell by a factor of roughly 3 -- between 60 and 70 percent. They found no statistically significant impact on federal prosecutions for political corruption of that decline in the number of journalists. However, each member of the [[w:Institute for Nonprofit News|Institute for Nonprofit News]] (INN) in a federal court district in one year was associated with on average 1.4 additional prosecutions for political corruption the following year. This suggests that the major media outlets that had so dramatically reduced their staffs had not substantively reduced the amount of investigative journalism they did. If we assume that the people prosecuted for political corruption also control substantive advertising budgets, then the major media outlets have conflicts of interest in honestly reporting on such. They may report on it if some other organization like a member of INN does the research and they are threatened with a loss of audience from not reporting on it. :'''''Major point''''': You and I benefit, the vast majority of humans on earth benefit, from news reports presumably published by members if INN that contributed to those on average 1.4 additional prosecutions for political corruption estimated by Usher and Kim-Leffingwell (2022). We benefit even if we never heard about the news reports that contributed to those prosecutions. We benefit even if we have never heard of the news outlets that presumably did the investigative journalism behind those additional prosecutions. Why? Because on average those news reports likely deterred other incidents of political corruption, which likely contributed to broadly shared economic growth and the development of new technology that ultimately benefit the vast majority of humanity. Other aspects of this are documented in the research on the impact of [[w:news desert|news desert]]s, which we summarize next. === Costs increase in news deserts=== There's a growing body of research describing what happens when local newspapers die. Perhaps most important, a 2018 research report by Gao et al. reported that the death of a local newspaper was followed by … increases in local tax revenue, averaging $85 per human per year.<ref name = Gao2018>Gao et al. (2018).</ref> That $85 was roughly 13 hundredths of a percent of the 2019 US GDP. That's mentioned in the 2025-07-17 interview with [[Democratic delusions: Fix the media to fix democracy|Natalie Fenton about her new book, ''Democratic Delusions, How the Media Hollows out democracy and What We Can Do About It'']]. One of the most spectacular example of the cost of a news desert is the [[w:City of Bell scandal|Scandal of Bell, California]]. Their local newspaper died around 1999. Roughly a decade later the city was nearly bankrupt in spite of having property tax rates among the highest in the nation. An investigation by the ''[[w:Los Angeles Times|Los Angeles Times]]'' documented that the city manager had a compensation package worth $1.5 million a year, well over double that of the President of the United States. Other senior city officials were similarly well-remunerated. Some of the city officials went to jail over that. Did the city manager decide after 1999, "Wow: The watchdog is dead. Let's have a party"? Malfeasance also increases in business as pollution and workplace accidents increase as does the cost of capital, because investors know their money is not as secure without a local newspaper. That leads to a reduction in investments in new products, services and processes -- slowing economic growth. See "[[Local newspapers limit malfeasance]]", esp. Kim et al. (2021). And executive compensation in increases in nonprofits, so less of what people donate goes to the charitable purpose for which they donated, according to Felix et al. (2024). Also, voter participation and split-ticket voting decline, per Benton (2019) and other references discussed in "[[Information is a public good: Designing experiments to improve government]]". And the ultra-right does better, as noted in [[News from Germany 1900-1945 and implications for today]] and the section on "[[Information is a public good: Designing experiments to improve government#Previous research|Previous research]]" in the Wikiversity article on "[[Information is a public good: Designing experiments to improve government]]".<ref>Flößer (2024).</ref> The 0.13 percent of GDP savings estimated by Gao et al. (2018) is roughly $120 per human per year. With over 300 million humans in the U.S, that is roughly $40 billion nationwide. {| class="wikitable" |+ Table 1. Costs increase in news deserts |- !

As documented with Figure 1 in the chapter below on [[/The impact of the media on political economy since the time of the Pharaohs/]], that growth catapulted the young United States into its current position of dominance in the international political economy, a position it has been losing since at least 1990 -- or since the Reagan Revolution began in 1981, according to the analysis in the chapter below on [[/Fox, the Great Depression, the Great Recession, and our future/]]. Other countries now have stronger democracies due in part to government subsidies for media in the range of 0.05 and 0.25 percent of GDP with a firewall that limits political interference in the content, according to Neff and Pickard (2024). Table 1 in "[[Information is a public good: Designing experiments to improve government]] compares media subsidies in various places with "other points of reference". McChesney and Nichols (2010, pp. 310-311, note 88) suggested that the relatively high rate of economic growth of the economy in the early US was due in part to postal subsidies under the US [[w:Postal Service Act|Postal Service Act]] of 1792.<ref>See also the Wikiversity article on "[[The Great American Paradox]]", accessed 2026-04-30.</ref> They estimated those subsidies at 0.21 percent of GDP. To improve the current political economy of the US, they recommended subsidies of 0.15 percent of GDP distributed to local news nonprofits on the basis of local elections.<ref>McChesney and Nichols (2021, 2022).</ref> The Wikipedia article on "[[Information is a public good: Designing experiments to improve government]]" documents how some jurisdictions can devote that much money to local news nonprofits by matching what they spend on accounting, advertising, and public relations.<ref>See the section on "[[Information is a public good: Designing experiments to improve government#Sampling units / experimental polities|Sampling units / experimental polities]]" in the Wikiversity article on "[[Information is a public good: Designing experiments to improve government]]", accessed 2026-04-30.</ref> Pickard (2023) describes three basic strategies for confronting concentrated commercial media power: (1) break them up, (2) regulate them, and (3) create non-commercial, public alternatives. A fourth possibility might be [[w:externality|a graduated tax on income and wealth]] in proportion to the threat that major corporations pose to democracy. One class of noncommercial alternatives that Packard mentions is local multi-media / Public Media Centers (PMCs) with management split between local journalists and boards, e.g., selected at random from registered voters. A key here is to have the boards selected in a way that cannot be influenced by people with power, whether business or political elites. Picard recommends considering '''six discrete layers''' when discussing PMCs, each of which, he says, must be radically democratised: # funding, # governance, # ascertainment (to determine a community’s ''critical information needs''), # infrastructure (including universal broadband service), # algorithmic (e.g., not allowing companies like Google and Facebook to suppress indexing information the might challenge their hegemony of those markets, [[w:Deep web|treating them like pedophilia and the Islamic State]]), # engagement, involving local communities in making their own news and in communicating their own stories; this is paramount to building trust and the grassroots-level support that this new local journalistic model requires. All this needs to be managed in ways that provide substantive support to news deserts and underserved communities that have long been subjected to various kinds of informational redlining. This might be done by including the proposed PMCs within local libraries staffed by professional journalists, who provide training in media literacy in local schools for children and supervise students producing school newspapers. Management of such PMCs might be split between journalists on staff and boards of, e.g., six members selected at random from voter registration rolls serving staggered terms of one year with a new member rotated in every 2 months. Another alternative that could be done in parallel with local PMCs calls for 200 journalists in each US Congressional district funded at $10 billion annually in 2022 dollars, which is just a little under 4 hundredths of one percent of GDP; if such allocations are expressed as fractions of a percent of GDP, they would grow naturally with the economy. (The nominal GDP for the US was roughly $26.1 trillion in 2022.<ref>Johnston and Williamson (2026).</ref> For 2026 it is estimated at $32.4 trillion.<ref>[[w:United States|United States]], accessed 2026-04-30.</ref>) A similar model is the [[w:BBC|BBC]]’s Local Democracy Reporting Service (LDRS), in which the BBC funds journalists to cover the work of local councils and other local public bodies, funded at £8 million per year, which is a little under 2 hundredths of a percent of the [[w:United Kingdom|UK]]'s GDP of £7.27 trillion.<ref>[[w:United Kingdom|United Kingdom]], accessed 2026-04-30.</ref> Pickard (2023) ended by saying, "Today we face a crossroads: technocracy and oligarchy from above or radical democracy and structural reform from below. ... [T]his is not just a journalism crisis: it is a democracy crisis." ==[proposed] Table of Contents== *[[/Introduction/]] including an exercise, asking all to discuss perceptions of the settlement of ''[[w:Dominion Voting Systems v. Fox News Network|Dominion Voting Systems v. Fox News Network]]'' in a friendly supportive manner with humans with whom they may vehemently disagree, because the alternative could be killing humans over misunderstandings. ===Part I. The media and political economy=== # [[/The impact of the media on political economy since the time of the Pharaohs/]] describes how hierarchical societies prior to [[w:James VI and I|King James of the King James bible]] were divided between those who fought, prayed, and worked. It was the responsibility of those who prayed to convince those who worked to live in poverty while giving increasing shares of what they produced so those who fought and prayed could live lives of leisure and opulence. During the reign of King James, pamphlets and newspapers began to compete with the church for helping commoners understand their roles in society. This produced the Industrial Revolution and modern democracies. Media consolidation since World War II gradually slowed and then reversed this trend. # [[/Fox, the Great Depression, the Great Recession, and our future/]] describes the unprecedented performance of the US political economy during the presidency of Franklin Roosevelt (FDR), insisting that much of what FDR achieved can be replicated, giving a media system that supports honest discussion of the available evidence. # [[/Media consolidation, social media, and political polarization/]] (Combine from McChesney and Nichols discussing the [[w:Postal Service Act|US Postal Service Act]] of 1792 with [[Media concentration per Columbia History Professor Richard John]], the section on "[[v:Information is a public good: Designing experiments to improve government#Threats from social media|Threats from social media]]" in "[[Information is a public good: Designing experiments to improve government]], and the comments by [[v:Facebook whistleblower Frances Haugen says|Facebook whistleblower Frances Haugen that, "the shortest path to a click is anger or hate."]]. ===Part II. The media and war=== # [[/Deterrence without threat/]] (Draft in [https://peaceworkskc.org/deterrence-without-threat/ "Deterrence without threat" on the website of PeaceWorks Kansas City], noting that the historical record is clear: Nations that have prepared for war often got war, not peace. This happens for at least two reasons: First, some leaders cannot resist the temptation to use force inappropriately, sometimes clandestinely provoking others to do things that are then denounced as "unprovoked". Alternatively, potential adversaries may believe -- or claim -- that you are actually preparing a first strike, and they must move preemptively or lose their ability to retaliate adequately. We can avoid these possibilities with three supportive policies: [a] Legislation that ''prohibits'' projecting force beyond our own borders. [b] Civilian-based defense training in nonviolent noncooperation like what helped Denmark survive Nazi occupation with minimal damage. And [c] A media system that makes it harder for the people who control most of the money for the media to create an environment that makes it hard for common folk to understand, "Why they hate us", and that encourages leaders to be more bellicose than would best support broadly shared peace and prosperity. It is naive to assume that (i) military command, control and communications systems never malfunction, (ii) potential adversaries will behave as we expect, and (iii) no one wants to initiate Armageddon. Supporters of the current US system claim that (i) is virtually foolproof, though [[w:Daniel Ellsberg|Daniel Ellsberg]], who was a nuclear war planner prior to releasing the Pentagon Papers, disagrees; see [[w:Gold Codes|Gold Codes]]. The other two assumptions are demonstrably false. Under current practice, major media can defame poor folk and foreigners with impunity. Major wars like the US-led invasions of Iraq in 2003, Afghanistan in 2001, and Vietnam decades earlier might have played out very differently if individual foreigners and foreign governments had successfully sued the major US media, especially the [[w:Big Three (American television)|Big three US television networks]], [[w:NBC|NBC]], [[w:CBS|CBS]], and [[w:American Broadcasting Company|ABC]], for defamation following the principle in ''[[w:New York Times Co. v. Sullivan|New York Times Co. v. Sullivan]]''.) Another policy for parties to the [[w:Treaty on the Prohibition of Nuclear Weapons|Treaty on the Prohibition of Nuclear Weapons]] (TPNW) would be to institute gradually increasing tariffs on trade with nuclear-weapon states. Free trade agreements supported by the [[w:World Trade Organization|World Trade Organization]] allow exemptions for national security and other objectives. Even a minor nuclear war between India and Pakistan would have a negative impact on the entirety of humanity. It therefore seems sensible for parties to the TPNW to institute gradually increasing tariffs on nuclear weapon states, not so great as to seriously impact the economies of parties to the TPNW but aggressive enough to gradually wean their economy from reliance on trace with nuclear-weapon states.

'''Think before you share''': [[Facebook whistleblower Frances Haugen says|Facebook whistleblower Frances Haugen said]], "The shortest path to a click is anger or hate." The social psychology behind this phenomenon exploited also by legacy media has contributed to [[Media Literacy and You/Media consolidation, social media, and political polarization|the dramatic increase in political polarization and violence worldwide]], especially since the end of the [[w:Fairness doctrine|Fairness doctrine]] in 1987. To counter this, DiResta (2024, p. 335) recommends, "Think before you share." :2. '''Disconfirmation bias''': [[w:Information is a public good: Designing experiments to improve government#Previous research|Virtually everyone]] (a) thinks they know more than they do ([[w:Overconfidence effect|overconfidence effect]]), and (b) prefers information and sources consistent with preconceptions ([[w:Confirmation bias|confirmation bias]]). The major media everywhere exploit this to please those who control most of the money for the media. Humans can counter this by searching for sources to help us understand our designated enemies. If we cannot explain circumstances under which we could see ourselves doing what we see our designated enemies doing, we haven't looked hard enough. :3. '''Talk''': Push ourselves to have friendly supportive conversations with others with whom we may vehemently disagree with the goals of agreeing to disagree agreeably and building collaboration on areas of common concern. :4. '''Teach''': Humans who develop skills in the first three levels can leverage that knowledge in helping others acquire those skills. If each one teaches two<ref>"[[:w:Each one teach one|Each one teach one]]" is an African-American proverb from the time of legalized slavery. However, if each one teaches only one, the growth in literacy will only be linear. Having "each one teaching two", on average, unleashes the power of doubling and [[:w:exponential growth|exponential growth]], which has the potential of educating the entirety of humanity in a reasonable period of time -- namely after 33 doublings starting from one.</ref> in a certain period of time, that time period becomes a [[:w:Doubling time|doubling time]].

Much of this book is a [[w:Monograph|research monograph]] summarizing research that seems to have been underreported by the major media to avoid offending people who control most of the money for the media. These research results seem to be central to major political divisions. Each chapter ends in exercises to help the reader practice media literacy skills and have fun doing it. Remember: :''I am entitled to my [[Wiktionary:cockamamie|cockamamie]] ideas, and you are entitled to yours.'' Humor is important but must be offered in a way that does not offend others. If others are offended, they may be less interested in dialogue. The term "cockamamie" is used here, hoping that this style of [[w:Self-deprecation|self-deprecation]] might be more inviting for dialogue.

Argentine journalist [[w:Horacio Verbitsky|Horacio Verbitsky]] said, "Journalism is disseminating information that someone does not want known; the rest is [[w:propaganda|propaganda]]."<ref>p. 16 in Verbitsky (1997); English translation from [[Wikiquote:Horacio Verbitsky]], accessed 2026-02-09.</ref> * The major media everywhere create the stage upon which politicians read their lines. :- Their selection of acceptable topics for news and entertainment create and maintain the "[[w:Overton window|Overton window]]", which is the range of acceptable political discourse. For example, in early 1964, US President [[w:Lyndon B. Johnson|Lyndon Johnson]] understood that he could lose the 1964 presidential election that year if he were seen to be soft on communism. His response was to clandestinely provoke an attack on US naval vessels in the Gulf of Tonkin, which he could then denounce as "unprovoked". During a dark and stormy night 1964-08-04 the [[w:USS Maddox (DD-731)|USS ''Maddox'']] and [[w:USS Turner Joy|''Turner Joy'']] spent a couple of hours "defending themselves" against radar snow, then [[w:Gulf of Tonkin incident|reported that they had sunk two attacking North Vietnamese torpedo boats]]; subsequent investigations found no evidence of the reported attacks. That incident was used to justify the [[w:Gulf of Tonkin Resolution|Gulf of Tonkin Resolution]], with only two dissenting votes in the US Congress: Those two dissenters were defeated in their next reelection campaigns, illustrating the point that the major media create the environment in which many politicians cannot get elected without betraying the nation. === The value of noncommercial news outlets === Some of the problems with the media and their contributions to increasing political polarization and violence are documented in the research summary on "[[Information is a public good: Designing experiments to improve government]]" and in the podcast series available on Wikiversity under "[[:Category:Media reform to improve democracy]]" with leading experts discussing their recommendations. One of the most compelling of the references discussed in that podcast series is Usher and Kim-Leffingwell (2022), who tallied all the federal prosecutions for political corruption in each of the 94 [[w:United States federal judicial district|US federal court district]]s between 2003 and 2019. During that period, the number of journalists in the US fell by a factor of roughly 3 -- between 60 and 70 percent. They found no statistically significant impact on federal prosecutions for political corruption of that decline in the number of journalists. However, each member of the [[w:Institute for Nonprofit News|Institute for Nonprofit News]] (INN) in a federal court district in one year was associated with on average 1.4 additional prosecutions for political corruption the following year. This suggests that the major media outlets that had so dramatically reduced their staffs had not substantively reduced the amount of investigative journalism they did. If we assume that the people prosecuted for political corruption also control substantive advertising budgets, then the major media outlets have conflicts of interest in honestly reporting on such. They may report on it if some other organization like a member of INN does the research and they are threatened with a loss of audience from not reporting on it. :'''''Major point''''': You and I benefit, the vast majority of humans on earth benefit, from news reports presumably published by members if INN that contributed to those on average 1.4 additional prosecutions for political corruption estimated by Usher and Kim-Leffingwell (2022). We benefit even if we never heard about the news reports that contributed to those prosecutions. We benefit even if we have never heard of the news outlets that presumably did the investigative journalism behind those additional prosecutions. Why? Because on average those news reports likely deterred other incidents of political corruption, which likely contributed to broadly shared economic growth and the development of new technology that ultimately benefit the vast majority of humanity. Other aspects of this are documented in the research on the impact of [[w:news desert|news desert]]s, which we summarize next. === Costs increase in news deserts=== There's a growing body of research describing what happens when local newspapers die. Perhaps most important, a 2018 research report by Gao et al. reported that the death of a local newspaper was followed by … increases in local tax revenue, averaging $85 per human per year.<ref name = Gao2018>Gao et al. (2018).</ref> That $85 was roughly 13 hundredths of a percent of the 2019 US GDP. That's mentioned in the 2025-07-17 interview with [[Democratic delusions: Fix the media to fix democracy|Natalie Fenton about her new book, ''Democratic Delusions, How the Media Hollows out democracy and What We Can Do About It'']]. One of the most spectacular example of the cost of a news desert is the [[w:City of Bell scandal|Scandal of Bell, California]]. Their local newspaper died around 1999. Roughly a decade later the city was nearly bankrupt in spite of having property tax rates among the highest in the nation. An investigation by the ''[[w:Los Angeles Times|Los Angeles Times]]'' documented that the city manager had a compensation package worth $1.5 million a year, well over double that of the President of the United States. Other senior city officials were similarly well-remunerated. Some of the city officials went to jail over that. Did the city manager decide after 1999, "Wow: The watchdog is dead. Let's have a party"? Malfeasance also increases in business as pollution and workplace accidents increase as does the cost of capital, because investors know their money is not as secure without a local newspaper. That leads to a reduction in investments in new products, services and processes -- slowing economic growth. See "[[Local newspapers limit malfeasance]]", esp. Kim et al. (2021). And executive compensation in increases in nonprofits, so less of what people donate goes to the charitable purpose for which they donated, according to Felix et al. (2024). Also, voter participation and split-ticket voting decline, per Benton (2019) and other references discussed in "[[Information is a public good: Designing experiments to improve government]]". And the ultra-right does better, as noted in [[News from Germany 1900-1945 and implications for today]] and the section on "[[Information is a public good: Designing experiments to improve government#Previous research|Previous research]]" in the Wikiversity article on "[[Information is a public good: Designing experiments to improve government]]".<ref>Flößer (2024).</ref> The 0.13 percent of GDP savings estimated by Gao et al. (2018) is roughly $120 per human per year. With over 300 million humans in the U.S, that is roughly $40 billion nationwide. {| class="wikitable" |+ Table 1. Costs increase in news deserts |- !

As documented with Figure 1 in the chapter below on [[/The impact of the media on political economy since the time of the Pharaohs/]], that growth catapulted the young United States into its current position of dominance in the international political economy, a position it has been losing since at least 1990 -- or since the Reagan Revolution began in 1981, according to the analysis in the chapter below on [[/Fox, the Great Depression, the Great Recession, and our future/]]. Other countries now have stronger democracies due in part to government subsidies for media in the range of 0.05 and 0.25 percent of GDP with a firewall that limits political interference in the content, according to Neff and Pickard (2024). Table 1 in "[[Information is a public good: Designing experiments to improve government]] compares media subsidies in various places with "other points of reference". McChesney and Nichols (2010, pp. 310-311, note 88) suggested that the relatively high rate of economic growth of the economy in the early US was due in part to postal subsidies under the US [[w:Postal Service Act|Postal Service Act]] of 1792.<ref>See also the Wikiversity article on "[[The Great American Paradox]]", accessed 2026-04-30.</ref> They estimated those subsidies at 0.21 percent of GDP. To improve the current political economy of the US, they recommended subsidies of 0.15 percent of GDP distributed to local news nonprofits on the basis of local elections.<ref>McChesney and Nichols (2021, 2022).</ref> The Wikipedia article on "[[Information is a public good: Designing experiments to improve government]]" documents how some jurisdictions can devote that much money to local news nonprofits by matching what they spend on accounting, advertising, and public relations.<ref>See the section on "[[Information is a public good: Designing experiments to improve government#Sampling units / experimental polities|Sampling units / experimental polities]]" in the Wikiversity article on "[[Information is a public good: Designing experiments to improve government]]", accessed 2026-04-30.</ref> Pickard (2023) describes three basic strategies for confronting concentrated commercial media power: (1) break them up, (2) regulate them, and (3) create non-commercial, public alternatives. A fourth possibility might be [[w:externality|a graduated tax on income and wealth]] in proportion to the threat that major corporations pose to democracy. One class of noncommercial alternatives that Packard mentions is local multi-media / Public Media Centers (PMCs) with management split between local journalists and boards, e.g., selected at random from registered voters. A key here is to have the boards selected in a way that cannot be influenced by people with power, whether business or political elites. Picard recommends considering '''six discrete layers''' when discussing PMCs, each of which, he says, must be radically democratised: # funding, # governance, # ascertainment (to determine a community’s ''critical information needs''), # infrastructure (including universal broadband service), # algorithmic (e.g., not allowing companies like Google and Facebook to suppress indexing information the might challenge their hegemony of those markets, [[w:Deep web|treating them like pedophilia and the Islamic State]]), # engagement, involving local communities in making their own news and in communicating their own stories; this is paramount to building trust and the grassroots-level support that this new local journalistic model requires. All this needs to be managed in ways that provide substantive support to news deserts and underserved communities that have long been subjected to various kinds of informational redlining. This might be done by including the proposed PMCs within local libraries staffed by professional journalists, who provide training in media literacy in local schools for children and supervise students producing school newspapers. Management of such PMCs might be split between journalists on staff and boards of, e.g., six members selected at random from voter registration rolls serving staggered terms of one year with a new member rotated in every 2 months. Another alternative that could be done in parallel with local PMCs calls for 200 journalists in each US Congressional district funded at $10 billion annually in 2022 dollars, which is just a little under 4 hundredths of one percent of GDP; if such allocations are expressed as fractions of a percent of GDP, they would grow naturally with the economy. (The nominal GDP for the US was roughly $26.1 trillion in 2022.<ref>Johnston and Williamson (2026).</ref> For 2026 it is estimated at $32.4 trillion.<ref>[[w:United States|United States]], accessed 2026-04-30.</ref>) A similar model is the [[w:BBC|BBC]]’s Local Democracy Reporting Service (LDRS), in which the BBC funds journalists to cover the work of local councils and other local public bodies, funded at £8 million per year, which is a little under 2 hundredths of a percent of the [[w:United Kingdom|UK]]'s GDP of £7.27 trillion.<ref>[[w:United Kingdom|United Kingdom]], accessed 2026-04-30.</ref> Pickard (2023) ended by saying, "Today we face a crossroads: technocracy and oligarchy from above or radical democracy and structural reform from below. ...

Fox News Network|Dominion Voting Systems v. Fox News Network]]'' in a friendly supportive manner with humans with whom they may vehemently disagree, because the alternative could be killing humans over misunderstandings. ===Part I. The media and political economy=== # [[/The impact of the media on political economy since the time of the Pharaohs/]] describes how hierarchical societies prior to [[w:James VI and I|King James of the King James bible]] were divided between those who fought, prayed, and worked. It was the responsibility of those who prayed to convince those who worked to live in poverty while giving increasing shares of what they produced so those who fought and prayed could live lives of leisure and opulence. During the reign of King James, pamphlets and newspapers began to compete with the church for helping commoners understand their roles in society. This produced the Industrial Revolution and modern democracies. Media consolidation since World War II gradually slowed and then reversed this trend. # [[/Fox, the Great Depression, the Great Recession, and our future/]] describes the unprecedented performance of the US political economy during the presidency of Franklin Roosevelt (FDR), insisting that much of what FDR achieved can be replicated, giving a media system that supports honest discussion of the available evidence. # [[/Media consolidation, social media, and political polarization/]] (Combine from McChesney and Nichols discussing the [[w:Postal Service Act|US Postal Service Act]] of 1792 with [[Media concentration per Columbia History Professor Richard John]], the section on "[[v:Information is a public good: Designing experiments to improve government#Threats from social media|Threats from social media]]" in "[[Information is a public good: Designing experiments to improve government]], and the comments by [[v:Facebook whistleblower Frances Haugen says|Facebook whistleblower Frances Haugen that, "the shortest path to a click is anger or hate."]]. ===Part II. The media and war=== # [[/Deterrence without threat/]] (Draft in [https://peaceworkskc.org/deterrence-without-threat/ "Deterrence without threat" on the website of PeaceWorks Kansas City], noting that the historical record is clear: Nations that have prepared for war often got war, not peace. This happens for at least two reasons: First, some leaders cannot resist the temptation to use force inappropriately, sometimes clandestinely provoking others to do things that are then denounced as "unprovoked". Alternatively, potential adversaries may believe -- or claim -- that you are actually preparing a first strike, and they must move preemptively or lose their ability to retaliate adequately. We can avoid these possibilities with three supportive policies: [a] Legislation that ''prohibits'' projecting force beyond our own borders. [b] Civilian-based defense training in nonviolent noncooperation like what helped Denmark survive Nazi occupation with minimal damage. And [c] A media system that makes it harder for the people who control most of the money for the media to create an environment that makes it hard for common folk to understand, "Why they hate us", and that encourages leaders to be more bellicose than would best support broadly shared peace and prosperity. It is naive to assume that (i) military command, control and communications systems never malfunction, (ii) potential adversaries will behave as we expect, and (iii) no one wants to initiate Armageddon. Supporters of the current US system claim that (i) is virtually foolproof, though [[w:Daniel Ellsberg|Daniel Ellsberg]], who was a nuclear war planner prior to releasing the Pentagon Papers, disagrees; see [[w:Gold Codes|Gold Codes]]. The other two assumptions are demonstrably false. Under current practice, major media can defame poor folk and foreigners with impunity. Major wars like the US-led invasions of Iraq in 2003, Afghanistan in 2001, and Vietnam decades earlier might have played out very differently if individual foreigners and foreign governments had successfully sued the major US media, especially the [[w:Big Three (American television)|Big three US television networks]], [[w:NBC|NBC]], [[w:CBS|CBS]], and [[w:American Broadcasting Company|ABC]], for defamation following the principle in ''[[w:New York Times Co. v. Sullivan|New York Times Co. v. Sullivan]]''.) Another policy for parties to the [[w:Treaty on the Prohibition of Nuclear Weapons|Treaty on the Prohibition of Nuclear Weapons]] (TPNW) would be to institute gradually increasing tariffs on trade with nuclear-weapon states. Free trade agreements supported by the [[w:World Trade Organization|World Trade Organization]] allow exemptions for national security and other objectives. Even a minor nuclear war between India and Pakistan would have a negative impact on the entirety of humanity. It therefore seems sensible for parties to the TPNW to institute gradually increasing tariffs on nuclear weapon states, not so great as to seriously impact the economies of parties to the TPNW but aggressive enough to gradually wean their economy from reliance on trace with nuclear-weapon states.

The nation shares a border to the north with the United States and its southern borders with Guatemala and Belize. Mexico’s legal system has its roots in the Civil Law Tradition due in large part to its ties to Spain. The Mexican legal system also takes inspiration from Roman law, canon law, and medieval commercial law. The current Mexican Constitution is commonly referred to as the 1917 Constitution but more formally known as the Political Constitution of the United Mexican States. The federal judiciary in Mexico is governed by Articles 94 through 107 of the Constitution and the Organic Law of the Federal Judiciary. The system establishes circuit judges, district judges and the Supreme Court of Justice of the Nation (“SCJN” which contains 11 Justices and 1 Chief Justice).[1] Historical jurisprudence before 1917 has no binding force.[2] Additionally, the legal principle of stare decisis, a common law tradition, is not recognized by the civil law tradition because civil law is created by legal scholars and not by judges.[3] == '''Primary Sources of Mexican Communications Law''' == === '''National Law''' === ==== '''Constitutional Law''' ==== The most important place to begin the analysis of communication law in Mexico is the document that governs the land itself, the Constitution. The Mexican Constitution was adopted in 1917 after the Mexican Revolution and reflects the countries commitment to social justice and constitutional democracy. Article 2 of the Constitution creates substantive state duties and communication rights that requite the federal government to protect free information by ensuring that Indigenous communities are able to access media and communication channels. [4] Article 2(B)(II) states that authorities are obligated to: extend the communication infrastructure, enable integration of communities to the rest of the country, by constructing and expanding transportation routes & telecommunications means and support productive activities and sustain development of indigenous communities through actions that allow them to achieve economic self-sufficiency such as the use of new technology to increase productive capacity. [5] Article 6(b)(ii) labels telecommunications as public services of general interest and mandates that the State guarantee “quality, plurality, universal coverage, interconnection, convergence, continuity, free access, and free from arbitrary interferences.[6] ==== '''Statutory Framework''' ==== As the Constitution was adopted in 1917 before the age of the internet and media, statutes regulate telecommunication. Since 2014, Mexican communications law has been governed by the “''Federal Telecommunications and Broadcasting Law”'' which is intended to regulate the use, development, and operation of the radio spectrum, the public telecommunication networks, access to active and passive infrastructure, satellite orbits, public broadcasting, rights of users and audiences and competition processes in these sectors. The Mexican Senate and Chamber of Deputes approved legislation in July of 2025 that replaced the previous legal framework. This 2025 Federal Telecommunications and Broadcasting Law initiated significant institutional regulatory body restructuring in an effort to combat poverty as around 46.8% of the population live in poverty and do not have access to digital infrastructure. [7] The LMTR governs broadcasting, telecommunication services, user and audience rights, infrastructure sharing and interconnection and network access.[8] === '''National Regulatory Bodies''' === In Mexico, all telecommunication regulations are governed by the Federal Telecommunications and Broadcasting Law, which forms the legal framework for internet services, broadcasting, and telecom infrastructure. These laws are enforced by the Federal Telecommunications Institute who is an independent regulatory agency. The FTI oversees and regulates internet, television, radio and mobile services across Mexico and has the ability to submit policy recommendations. The Federal Telecommunications Institute (FTI) is the independent regulator for broadcasting and telecommunications and oversees all competition, consumer protection and spectrum use. The FTI was established in 2013 and was tasked with breaking apart monopolies, increasing transparency and ensuring that the regulation remained apolitical. The FTI oversees and regulates internet, television, radio and mobile services across Mexico and has the ability to submit policy recommendations. The Agency for Digital Transformation and Telecommunications (ATDT) manages private and public telecommunication corporations and projects. The ATDT has the authority to temporarily block digital platforms in non-compliance upon request by the competent authority and established a mobile user database. The Telecommunications Regulatory Commission (TRC) is a decentralized body within the Agency itself that has operational and technical autonomy. It is comprised of 5 commissioners nominated by the President and ratified by the Senate who will be responsible for granting concessions, authorization and registration certificates. Additionally, the TRC will be manage bidding processes and assignment of frequency bands and orbital resources. === '''Regional & International Law Sources of Communication Law:''' === These international treaties and agreements influence the structure and coverage of Mexican domestic communication law. The following are regional trade agreements that influence telecommunication law. The United States-Mexico-Canada (USMCA) Agreement is an agreement between America and Mexico. The U.S. is Mexico’s largest trading partner which incentivizes the need for the USMCA. Chapter 18 Telecommunications includes provisions that restrict dominant telecommunication organizations from blocking international competitors from entering the market (Mexican Supreme Court case regarding “Movil”.[9] Other provisions within this Agreement mandate all providers to offer interconnection at reasonable rates, ban unreasonable conditions on resale of telecommunication services to competitors and declare that market forces may be more appropriate than regulation in setting up telecommunications. The American Convention on Human Rights (Pact of San Jose) was ratified by Mexico ratified in 1981 and granted the Inter-American Court of Human Rights (IACHR) jurisdiction in 1998.[10] This implies that Mexico must comply with the Convention and with the Court’s judicial rulings.[11] In 2006, the IACHR began taking an active role in verifying that domestic judges, from countries that signed the Convention, ensured national laws were consistent with the Pact of San Jose.[12] This is accomplished through a conventionality review, which requires that domestic judges articulate their decisions on cases that involve human rights and do not adhere to the Convention.[13] Since its adoption, the Mexican government has consistently requested the opinion of the IACHR on issues related to human rights, but the Mexican government has not always been collaborative. Fortunately, Mexico passed a constitutional reform in 2011 that changed several articles to require all state authorities to take the constitution and international treaties, which Mexico is a party to, into consideration when the matter is related to human rights. Article 13(3) Freedom of Thought and Expression states that the right of expression shall not be restricted by indirect methods or means such as the private controls of newsprint, radio broadcasting frequencies, or equipment used in the dissemination of information or by any other means tending to impede the communication and circulation of ideas and opinions.[14] The following are international agreements that influence telecommunication law. The International Telecommunications Union (ITU) is a United Nations agency that coordinates global telecommunications policy. ITU policies are incorporated into Mexico’s domestic regulatory practice. The ITU facilitates international communication networks, coordinates global standards for broadband, wireless, optical fiber etc., and strives for universal access.[15] The World Trade Organization, Basic Telecommunications Agreement states that member countries agree to open their markets to foreign carriers for telecommunication services. Additionally, domestic providers and carriers will be treated as equals to foreign providers. This ensures that Mexican-owned telecommunication companies are treated fairly in foreign countries as long as Mexico treats foreign telecommunication companies equally. United Nations Educational, Scientific, and Cultural Organization (UNESCO): Mexico has been a member of UNESCO since 1946.[16] UNESCO plays a critical role in promoting freedom of expression, education, media pluralism, and access to information. UNESCO strongly encourages participant countries to prohibit censorship and maintain independent media. Additionally, UNESCO is vocal about the dangers of monopolies in broadcasting, communication infrastructure, and media.[17] == '''Unit 2: The Media''' == Telecommunication markets are vulnerable to high levels of concentration due to infrastructure being expensive and due to large entities benefiting from the events of operating its own network.[18] As previously mentioned, the primary statute regulating media and telecommunications in Mexico is the Federal Telecommunications and Broadcasting Law (FTBL). Recent amendments to Article 28 authorized the FTI to identify and impose regulations on companies that are dominating broadcasting or telecommunications markets. This reform created the concept of a “preponderant economic agent,” which is given to any company that controls more than 50% of the national market in Mexico in broadcasting or telecommunications. This distinction is reached by measuring the amount of revenue, the amount of infrastructure control, and the number of individuals using the broadcasting or telecommunications service. This reform was incredibly important to Mexican telecommunication and broadcasting regulation as Mexico had very high levels of market concentration where between one to three corporations-controlled majority of the market. [[File:The tournament of today - a set-to between labor and monopoly - F. Graetz. LCCN2012645501.jpg|thumb]] For decades, ''America Movil'' was the dominant power in telecommunication services through itself and its subsidiaries, Telcel and Telmex. This concentration of power created massive issues for smaller providers who were attempting to enter the market because constructing and maintaining the infrastructure required massive financial undertakings. In 2021, the Supreme Court of Justice of the Nation upheld the FTI’s decision to classify ''America Movil'' as a preponderant economic agent. America Movil argued that the restrictions set by the regulator restricted their constitutional right and economic freedoms and were unfairly only applicable to them, however America Movil dominated majority of the market through its subsidiaries Telcel and Telmex. The FTI imposed obligations and restrictions on Movil to share infrastructure with smaller telecommunication groups, publish pricing information, unbundle its networks, mandate interconnections. . . all designed to reduce monopolistic practices. Supporters argued that these regulations were necessary and vital because new entities and telecommunication groups could not replicate the same level of service. These restrictions act to promote competition and reduce the barriers to entering the telecommunications industry. Ultimately, the Court concluded that the FTI had the ability to regulate America Movil and impose these regulations on any corporation who meets the preponderant agent standard. These reforms represent a positive stride towards balancing government interest in preventing the formation of monopolies in essential sectors and promoting free markets. In essence, these reforms promote competition by reducing barriers for new telecommunication agencies which in turn expands choices for consumers. == '''Unit 3: Censorship and Violent Content''' == === '''Constitutional Protections''' === Freedom of speech and the press are constitutional rights in Mexico; however, the application of these rights have been contested and complex. Article 6 of the 1917 Constitution protects freedom of expression by prohibiting censorship and safeguarding the publication, paper, and internet, on many subjects although there are exceptions to these rights.[19] Furthermore, Article 7 states that freedom of speech, opinion, ideas and information shall not be abridged nor shall it be aimed at impeding transmission or circulation of ideas and opinions. [20] However, these expressions may be restricted if they infringe on the rights of others, offend good morals, incite crime, or disturb public order. Overall, Mexico’s constitutional approach demonstrates an equal weighing of competing interests by allowing freedom of expression while restricting expression that may harm public order or morality. ==== '''Violent Content''' ==== Mexico does not have a general federal statute that regulates violent content on social media platforms. However, Mexican authorities do have the ability to issue specific orders if the social media content violates criminal law by inciting violence, threats or child pornography. Mexico has passed a federal statute that addresses harmful and violent content on digital platforms, which is known as the General Law on Women’s Access to a Life Free of Violence.[21] Article 20 lays the groundwork by stating that “digital violence is any malicious action carried out through the use of information and communication technologies, by which real or simulated images, audio. . . of intimate sexual content. . . are exposed, distributed, disseminated. . . without their approval and that causes psychological harm.”[22] Article 20d states that media violence is any act through which directly or indirectly promotes sexist stereotypes, advocates violence against women, gender discrimination . . . using media outlets and Article 21e grants the Public Prosecutor’s Office or judge the ability to order the necessary protection measures to the companies of digital platforms.[23] Digital platforms who do not comply can be subject to fines or civil liability. While framed within the context of preventing gender-based violence, these provisions and statutes create a basis for courts to order the removal of harmful, violent, or non-consensual content from digital platforms. ==== '''Cyberstalking/Online Harassment''' ==== Mexico’s constitutional commitment to protecting freedom of speech is seen in ''Amparo'' ''81/2025.'' Article 480 of the Puebla’s Penal Code, a regional/state law, was amended to state that a crime is committed by anyone who, “through the use of information and communication technologies, social networks, or email or any digital space, repeatedly or systematically carried out acts of surveillance, harassment, intimidation, or offense to another person, and as a consequence alters their daily life, disturbs their privacy or damages their physical or emotional integrity”. The Third District Judge in criminal matters in the State of Puebla declared the law to be unconstitutional due to its vague and confusing phrasing by refusing to define repeated or systematic, very little clarity on how allegations of this nature cause damage to physical integrity and exceptions labeled “behaviors of public interests” with no proper definition or example of what are “behaviors of public interest.” ==== '''Illegal Pornography & Child Protection''' ==== Mexico strongly opposes and criminalizes child pornography. Article 202 of the Federal Criminal Code criminalizes production, distribution, sale possession and storage of child pornography. [24] This law includes digital content such as videos and images and simulated or altered images.[25] Recent amendments have reacted to the modernization of the internet and artificial intelligence to include altered or simulated images of child pornography. Not only is Mexico’s criminalization of child pornography grounded in domestic law, but it is also grounded by its ratification of several international human rights treaties. Most notably, Mexico has ratified the UN Convention on the Rights of Children which requires member states to protect children from sexual exploitation and sexual abuse, including pornographic materials.[26] This treaty also includes coverage of altered or simulated images of children in sexual activities which is in full agreement with Mexico’s recent federal amendments. === '''Child Protection''' === Mexico also goes to extreme lengths to ensure that children are not being exposed to content on televisions or radios that include potentially harmful or explicit conduct. Article 4 of the Constitution broadly establishes that the best interests of the child are paramount.[27] The Federal Telecommunications and Broadcasting Law (FTBL) has several protections for minors which include restricted time slots for adult content, limits advertising tobacco, alcohol or other products, broadcast content classification by age, and restrictions on broadcast content. However, Mexico does not yet have a comprehensive federal statute that regulates internet content or social media content from private corporations by age-based classifications.[28] Mexico remains strongly committed to regulating content that depicts children in explicit and violent situations as well as protecting what minors are exposed to on all forms of media. Mexico has dealt with gang violence towards all people but specifically women and thus has passed the General Law on Women’s Access to a Life Free of Violence to strongly condemn and prosecute offenders. == '''Unit 4: Truth, Honor, and Tolerance''' == === '''Defamation and Libel''' === In one of the most significant rulings on defamation and the press involving Mexico, the United Nations Human Rights Committee (UNHRC) found that a Mexican state had violated Lydia Cacho Riberio, a journalist, freedom of expression. In July 2005, Lydia Cacho published “The Demons of Eden” which allegedly exposed a network of child exploitation and crimes that involved government officials. A businessman by the name of Jose Borge filed a criminal complaint of defamation and the Mexican police arrested Lydia in Cancun and detained her for 30 hours under defamation charges where she experienced severe mistreatment. Criminal proceedings were dropped and Lydia filed a communication with the UN under Article 19 which was a treaty ratified by Mexico. The Committee noted that Mexico failed to show that the arrest of a member of the press was proportionate or necessary and warned that this punitive response to Lydia’s book appeared to be an effort to chill the freedom of expression. === '''Reform to Defamation and Slander''' === Shortly after Mexico underwent major reform in the area of defamation and slander. In 2011, the Mexican Legislative bodies brought forth and passed significant reform to abolish federal criminal libel, slander and defamation and relegated them to the civil courts under moral damages. This legislation passed unanimously in the Senate and reflected bipartisan agreement that criminal defamation did not align with democratic standards. The amended version, Article 1916 of the Federal Civil Code defines defamation as follows: “moral damage is understood as the harm that a person suffers in their feelings, affections, beliefs, dignity, honor, reputation, private life or moral integrity. . . and the person responsible for that damage has the obligation to repair it by monetary compensation.”[29] The SCJN adopted a test, similar to ''New York Times v. Sullivan'' in USA jurisdictions, in ''Amparo Direct Revision 2044/2008''. The mayor of Acambaro decided to sue a newspaper director after the local newspaper published an interview with his former driver where it was alleged that the mayor had been using public resources for personal reasons, had misused municipal vehicles and due to comments about the mayor’s sexual history. The mayor claimed in court that these comments were untrue and harmed his reputation. The Court ultimately concluded that public officials must deal with grater public scrutiny because of the role itself and that comments about sexual history or conduct do not necessarily or immediately invade private life. The SCJN held that public officials seeking liability for defamatory statements to prove that the false statements were made with knowledge of falsity and disregard for the truth. This heightened standard encourages journalists to exercise their freedom of expression while disincentivizing journalists from intentionally spreading false statements.[30] Furthermore, Mexico is also part of the Inter'''-'''American Court of Human Rights which instructs countries that public officials must be able to tolerate more criticism than the average person and warns that criminal defamation statutes must be proportionate and not chill free speech or journalism. === '''Hate Speech''' === The Federal Government of Mexico has not created a broad hate speech statute like those found in the United States of America or European countries. Instead, the Constitution and cases from the Supreme Court of Justice of the Nation have defined speech that would fall under the hate speech bucket and not freedom of expression. Article 1 of the Mexican Constitution state that “any form of discrimination, based on ethnic or national origin, disabilities, sexual orientation . . . which violate the human dignity or seek to annul or diminish the rights and freedoms of the people, is prohibited.” The SCJN has established hate speech as conduct that promotes discrimination or violence against a person or group. The factual scenario for the case Direct Amparo in Review 2806/2012 is as follows: EHQ published a note in a newspaper referring to APH, another journalist, using homophobic and derogatory language and that his poor performance was due to his sexual orientation. The Court stated that these comments were not just strong criticism but were an offensive expression unrelated to the opinion expressed. The Court also recognized that media corporations/organizations have a social responsibility to prevent discriminatory discourse. Furthermore, Mexico is also part of the American Convention on Human Rights, otherwise known as the Pact of San Jose. Article 13(5) requires the states to prohibit “any propaganda for war and any advocacy of national, racial, or religious hatred that constitutes incitement to lawless violence. == '''Unit 5:''' '''Cultural Expressions''' '''& Religion in Education''' == Despite their general distrust and skepticism of the national government, Mexican citizens are very proud of their country and its cultural practices.[31] Mexico celebrates known holidays like New Years (Ano Nuevo), Easter week (Semana Santa), Christmas Eve and Christmas Day (Nochebuena and & Navidad). However, Mexico has several cultural festivals that are exclusive to itself or unique to the regional area. === Festivals === [[File:Carnaval tropical Paris 2014 Golden Stars 114 Guadeloupe.jpg|thumb]] The first holiday is Carnaval Guaymas, which is one of Mexico’s oldest celebrations, a regional public festival which includes colorful floats, parades, dancers, concerts, and fireworks. Carnaval Guaymas serves as a social gathering that symbolizes regional pride, Sonoran identity, and port-city heritage.[32] The festival has roots in Catholic tradition, as it precedes lent, reflecting temporary indulgence before sacrifice. The holiday was most recently held from February 12, 2026, to February 17, 2026, and had hundreds of thousands of visitors and participants. [33] The second holiday is the Cinco de Mayo which marks the Battle of Puebla on May 5, 1862, when Mexican forces defeated the French forces of Napoleon III. This festival is celebrated on May 5<sup>th</sup> every year with parades, music, speeches, and reenactments and is meant to symbolize Mexican resistance and sovereignty.[34] [[File:Gran Desfile del Día de Muertos 2033.jpg|thumb]] One of the largest and most well-known festivals is the Dia de los Muertos. This festival originated in the Aztec empire. The holiday honored and celebrated the Lady of the Dead, Mictecacihuatl, whose job it was to watch over the bones of past life that would be used to create new life in the land of the living.[35] The Spanish conquistadors conquered the Aztec Empire and infused Catholicism with the Day of the Dead. These modern-day celebrations, influenced by the Spanish, replaced Mictecacihuatl with la Catrina – a skeleton woman wearing a European hat adorned with flowers and feathers.[36] === '''Constitutional Protection of Religious Freedom in Mexico''' === In Mexico, religious freedom of expression and choice are enshrined in the Mexican Constitution and a protected right. Mexico does not have a national religion but ensures that Congress cannot dictate laws that establish or abolish any specific religion… Mexico has adopted a strict separation between church and state. Article 130 of the Mexican Constitution orders that ‘the historic principle of separation between the State and religion shall guide the provisions established in this article’.[37] ==== '''Secularism and the Separation of Church and State''' ==== As previously mentioned, Article 24 of the Constitution instructs Congress from establishing or prohibiting any religion and mandates the separation of church and state.[38] This is further supported by in Article 55 wherein ‘any elected official may not be a priest or minister of any religion’ although they may maintain and practice their own beliefs and Article 82 which prohibits any candidate for the Presidency from being a priest or minister of any religion.[39] Furthermore, Article 130 states that ‘the formation of any kind of political group or with a name containing any word or other symbol related to any religion is strictly prohibited’ and Article 82 prohibits any candidate for the Presidency from being a priest or minister of any religion.[40] Article 24 of the Mexican Constitution states that “every person has the right to have freedom of ethical convictions, of conscience and of religion, and to have or to adopt, as the cause may be, the one of her preferences and that such freedom includes the right to participate, individually mor collectively, in both public and private ceremonies, worship or religious acts of the respective cult, as long as they are not a felony or a misdemeanor punished by law”. [41] In essence, Article 24 guarantees the freedom to maintain ethical convictions of religion and the ability to participate in religious ceremonies and acts of worship. ==== '''Religion in Education''' ==== As stated in Article 3 Section I, the religion and education provided by the State shall be secular, therefore, state education shall be maintained entirely apart from any religious doctrine.[42] The Mexican Constitution elaborates that state education is based on scientific progress and democratic principles and shall contribute to human coexistence while being of quality. The Supreme Court of Justice reviewed the constitutionality of a statute passed by the State of Nuevo Leon. Article 7, Section XII of the statute stated that one of the aims of the state is to develop solitary attitudes in individuals and to create awareness for the respect of life “from conception until natural death”. As stated by the Supreme Court of Justice, Mexico’s constitution requires that public education be secular which means that the state must remain neutral on all religious beliefs such as questions about when life begins. Additionally, the Court interpreted this state goal was indoctrination into a single view and that the intent of this statute was related and in response to a constitutional abortion amendment. Ultimately, the Court concluded that the term was unconstitutional. [43] ==== '''Religious Expression''' ==== The Mexican Constitution grants individuals the protection of freedom of speech and expression. Mexico does not maintain a modern federal criminal law specifically prohibiting insults or offensive language towards religious beliefs. However, these expressions may be restricted if they infringe on the rights of others, offend good morals, incite crime, or disturb public order. == '''Module 6 – Privacy and Data Protection''' == === '''The Right to Access Information''' === In 2001, Oaxaca Group, a group of lawyers, reporters, and editors, joined forces to draft a freedom of information initiative.[44] The objective of the Oaxaca Group was to ensure that the new government would live up to the promise that they consistently stated during their campaign to bring about a transparent government.[45] This movement promoting transparency was inspired by human rights activists who were seeking information on state-sponsored crimes that had occurred in the years prior by prior Presidents, specifically the Tlatelolco Massacre. [46] The Oaxaca Group lobbied for the bill and assisted with revisions or edits that legislators found important and it unanimously passed on April 30, 2002. On June 10, 2002, President Vicente Fox signed the ‘Ley Federal de Transparencia y Acceso a la Informacion Publica Gubernamental’ (Federal Law on Transparency and Access to Public Information). This law created the Federal Institute for Access of Information which established a new international standard for independent FOI oversight. Additionally, this was the first law in Latin America to impose an obligation on the State to declassify and release any information on investigations relating to ‘grave violations of fundamental rights or crimes against humanity is at stake’.[47] President Fox released thousands of documents on June 18, 2002, and they displayed evidence of the State’s role in the surveillance, capture, and torture of tens of thousands of Mexican citizens. === '''Evolution of the Right to Access Information''' === In 2006, Mexico’s government feared that a new administration may look to gut or weaken the Federal Institute for Access of Information. Thus, Mexico’s government bolstered the Federal Law on Transparency and Access to Public Government Information through a substantial constitutional expansion to Article 6 of the Mexican Constitution.[48] The reform was passed by Congress and approved by the state legislature. The amendment established that access to public information stemming from government action was a constitutionally protected right and not merely a statutory right. The amendment established principles of transparency and provided minimum standards for access to public information at federal, state, and municipal levels.[49] Additionally, it also required that individuals store their documents in updated administrational archives, mandated expedited mechanisms of release of public information, and protects personal data and private lives of individuals.[50] As expected, this constitutional amendment did not come without challenge. In one instance, the Attorney General of the Republic of Mexico challenged provisions of state transparency laws on the grounds that they did not meet or comply with the federal constitutional standards established under Article 6 of the Mexican Constitution. The Supreme Court of Justice held that the amended Article 6 created a minimum baseline for transparency and access to public information and that no state or municipality was entitled to dilute or weaken constitutional rights. Another important case is ''Amparo'' 168/2011 where an individual was disappeared by Mexican state agents in the 1970s.[51] The individual’s family member was seeking information from a federal investigation by the Attorney General into the disappearance.[52] The Office of the Attorney General denied the request stating that the files were confidential and that prior requests were already submitted for these files.[53] The SCJN held that any allegation of forced disappearance constituted a grave human rights violation and that transparency in such situations is the constitutional mandate.[54] Ultimately, Mexico’s transparency reforms benefit democratic and human rights interests. Democracy will be promoted by allowing journalists, media, and even normal citizens to monitor government conduct, request documentation and even expose misconduct or abuses of power. Returning to the intent driving these reforms was the respect for human rights. The goal was to receive documentation from government investigations into individuals who were ‘disappeared’ before a previous administration, and it is now codified that there can be no exceptions to requested documents relating to missing persons. == '''Module 7: RIGHT TO BODILY, SPIRITUAL, & DIGITAL IDENTITY''' == === '''Digital Identity''' === On July 17, 2025, Mexico’s Congress approved reforms to the General Population Law and the General Law on Forced Disappearance that mandated the creation and usage of an identity document that contains biometric data. The biometric Population Registry Code (CURP) is an official identification document that is mandated and available in both physical and digital formats that will integrate fingerprints, iris scans, and photographs.[55] Mexico’s Congress stated it would be used for identity validation, immigration procedures, access to health services, legal processes, and to support the search for missing persons.[56] The biometric CURP will contain information on the following: names and surnames, date of birth, sex, place of birth, nationality, a photograph, a digital signature, fingerprints, iris scans, and an alphanumeric code containing 18 letters and numbers. The main purpose driving its creation is to help the combat Mexico’s missing persons crisis and to prevent the crime of identity theft that is occurring in organized crime and drug trafficking. Although government leaders have spoken out in public claiming that the CURP is not ‘mandatory, individuals against the CURP have stated that many essential documents and identifications will only be accessible via CURP and thus be required. === '''Storage of Digital Identity''' === Under the new law, the storage and management of the CURP will be administered by the Ministry of the Interior and the federal Digital Transformation Agency on a new platform. Mexican citizens will need to create a personal account on the ‘Llave MX’ portal, which provides them to obtain a digital identity connected to their personal information. However, the legislation eliminated the National Council for Regulatory Improvement and the National Observatory for Regulatory Improvement which provided oversight, review and transparency. The removal of these critical agencies and entities has cast doubt on whether the government can be monitored and held accountable as they collect, store and use biometric data. A lack of accountability or oversight from a separate government body or agency could lead to a tool of mass surveillance. === '''Mass Surveillance''' === Mass surveillance uses systems or technologies that collect, analyze, and generate data on indefinite or large numbers of people instead of limiting surveillance to individuals about which there is reasonable suspicion of wrongdoing.[57] Biometric data is uniquely dangerous because it describes the physiological and behavioral characteristics of individuals. [58] If the country adopting biometric data has a weak legal framework and weak safeguard, the technology poses a grave threat to privacy and personal security as biometric data can identify a person for their entire lifetime.[59] Opposition to this law have labeled it the “Spy Bill” as all data, ranging from access to public and private services, missing persons data, tax contributions, and others, will be kept in the Unique Identity Platform. Government entities like the National Intelligence Centre and National Guard will have complete access to the biometric data that is stored in the Unique Identity Platform. [60] Additionally, authorities will be able to view this data without a lawful court order, and individuals will not be made aware when their information has been viewed by authorities, how many times it has been viewed or even what agency viewed it. [61] Further concerns arise when one considers the Mexican government’s history with surveillance. Digital rights groups have recorded many instances of the government surveilling journalists and human rights defenders. Other specific examples include when Meta’s U.S. lawsuit proved that an Israeli cyberintelligence group spied on over 400 people in Mexico in 2019 and when a hacker working for the Sinaloa drug cartel obtained information from the technology of an FBI agent and used surveillance cameras in Mexico City to track and kill the FBI’s informants in 2018.[62] Finally, in March 2025, the United States requested that Mexico’s government share all biometric information of migrants, although the Mexican government declined merely because it did not yet have a catalog or biometric data ID system.[63] Ultimately, Mexico’s legal framework reflects a balancing of competing interests that has made progress but remains unfinished. The state’s need for security and public order are vital but proper watchdog and accountability mechanisms must be put in place to avoid infringements of constitutional rights and violations of privacy. == '''Unit 8: Consent of Acquisition of Private Information''' == [[File:Digital Safety and Privacy - Human Rights Team (1).pptx.pdf|thumb]] At the core of Mexico’s unique approach to private information is the ‘Ley Federal De Proteccion De Datos Personales en Posesion de los Particulares (Federal Law on the Protection of Personal Data Held by Private Parties).[64] This law is designed to protect individuals’ privacy by regulating how private entities can retain, process, store, or use personal data. Article 7 of the law requires that any processing of personal data shall require the consent of the individual unless specific exceptions apply.[65] This clause protects Mexican consumers and individuals who use their personal data in transactions on the internet or in-person. However, the Mexican government has established through Article 9 exceptions to the rule.[66] Article 9 of the Federal Law on the Protection of Personal Data Held by Private parties lays out that a controller is not required to obtain consent from an individual when required by law, the data appears in publicly accessible sources, when the data has undergone dissociations, or in medical emergencies. These exceptions balance two competing interests, privacy protection and practical governance, by allowing medical facilities to act quickly in emergency situations with private information and inversely restricting business entities from processing personal information from online transactions without consent.[67] === '''The Right to Reject Information''' === Privacy law in Mexico has given citizens control over how companies and private entities collect, use, store, and share their personal information. At the core of Mexico’s unique approach is the ‘Ley Federal De Proteccion De Datos Personales en Posesion de los Particulares (Federal Law on the Protection of Personal Data Held by Private Parties). This law sets out ‘ARCO rights’ which stand for rights of: access, rectification, cancellation, and opposition.[68] Access allows individuals or otherwise known as data subjects to know when companies possess their personal information, see how it is being used, and who it could be sent to among others. Under Article 28, an ARCO rights request must include the name of the data subject, address or notification method, proof of identity, description of the requested data, and description of the ARCO right exercised.[69] The controller must respond within twenty days and process the request within fifteen days if it is approved however Article 33 permits the controller to deny the request when the identity is not proven, a legal impediment exists, or the data is not held by the controller.[70] Article 23 states that rectification allows citizens to correct personal information that is in possession of the entity that is misleading, incomplete or incorrect.[71] Additionally, the individual must specify the exact information that requires modification and provide documentation that supports the modification.[72] The controller may deny if the data provided does not exist or legal impediments stand in the way. Cancellation allows citizens to request that personal information be removed from the database storing it after it becomes unnecessary to hold or a specific amount of time passes. Article 24 states that data subjects shall have the right to request cancellation of personal data from files, records, systems, and databases of the controller.[73] The data must then be put into a blocking period and subsequently deleted. Article 25 lists several exceptions that allow the controller to continue possessing the information such as when it may be necessary for contractual performance, serves public interest, is ordered by law to be retained, and would obstruct judicial proceedings.[74] Opposition allows citizens to oppose the processing of their personal information when: a legitimate cause exists and continued processing would case harm, or automated processing procedures produce unwanted legal effects or significantly affects the subject’s interests, rights or freedoms. Article 26 lists several factors that automated systems may use such as health, sexual preferences, and economic situation which are placed into a predictive analysis system or algorithm to specifically target the individual.[75] === '''Anti-Spam''' === [[File:No-spam.svg|thumb]] Mexico’s unsolicited marketing and anti-spam are enforced through the Federal Consumer Protection Law and the Public Registry to Avoid Advertising which are administered by the Federal Consumer Protection Agency. The Federal Consumer Protection Law gives consumers the ability to opt out of any unsolicited marketing communications and restricts entities from continuing to send advertising once the consumer has opted out.[76] Entities that violate these opt-outs may face sanctions or other penalties.[77] Additionally, Mexico has the Public Registry to Avoid Advertising which allows individuals to block telemarketing calls, text advertising, and other promotional communications with very limited exceptions by inputting their phone number and or email contact information.[78] ----[1] Francis A.

X<sub>1</sub> and X<sub>2</sub> represent two nearby points on both sides of the "hill" which both produce almost the same output. For both of the values, adding both X<sub>1</sub> and X<sub>2</sub> would equal <math display="inline">b</math> (the total length). B = x<sub>1</sub> + x<sub>2</sub> would come out to B = 2x, with '''x = b/2''' (where the maxima occurs). This is the value of <math display="inline">x</math> that would ideally give the highest value for <math display="inline">c</math> (see below). ==== Purpose of bx - x<sup>2</sup> = c? ==== What is the purpose of the equation (see https://youtube.com/AOKoo_nQSts?si=1RfOYMAHm-Ll5sVT&t [minute 4:17] for context/writing of this equation): <math display="inline">bx</math> - <math display="inline">x</math><sup>2</sup> = <math display="inline">c</math>? If we take a line (total = <math display="inline">b</math>), and make a cut at some point in the line (and designate the cut 'mark' as <math display="inline">x</math>), how could we figure out <math display="inline">c</math> (output produced by the equation, <math display="inline">bx</math> - <math display="inline">x</math><sup>2</sup> = <math display="inline">c</math>)? <math display="inline">x</math> represents a portion of the line, while <math display="inline">b - x</math> represents the remaining portion of the line.

She has held other other positions protecting democracy including as an intelligence officer, diplomat, and White House advisor.

Conversations with others in the US were becoming more difficult than conversations she had had as a CIA officer and diplomat drinking tea and talking with outspoken anti-Western clerics and suspected terrorists in Africa. Many of those engagements began with mutual suspicion but none degenerated into shouting or insults. In some cases she built collaboration on areas of mutual interest. Her most powerful tools were to listen, learn and build empathy. Most of her contacts wanted to feel heard, validated and respected. But social media companies like [[w:Facebook|Facebook]] incentivize inflammatory content contributing to a culture of political polarization and mistrust. This generates revenue for Facebook and similar companies that make money from clicks, "because the shortest path to a click is anger or hate", in the words of [[Facebook whistleblower Frances Haugen says|Facebook whistleblower Frances Haugen]], interviewed 2024-08-19 for this Media & Democracy series. When Facebook asked Eisenstat in 2018 to lead their work to support global elections integrity for political ads, she agreed. She left six months later, speaking openly about Facebook's inability to meet its responsibility to secure elections, subsequently documented, e.g., in the thousands of internal Facebook documents that [[w:Frances Haugen|Haugen]] released to the [[w:Securities and Exchange Commission|Securities and Exchange Commission]] and ''[[w:The Wall Street Journal|The Wall Street Journal]]'' in 2021. === 2020 SXSW panel === Eisenstat was part of a "panel about the Future of Tech Responsibility" for the 2020 [[w:South by Southwest|South by Southwest]] festival. The festival was cancelled due to COVID-19, but the panel was held virtually. This panel included a discussion of [[w:Section 230|Section 230]] of the [[w:Communications Act of 1934|Communications Act of 1934]], as amended by the [[w:Communications Decency Act|Communications Decency Act]] of 1996.<ref>Reid (2020).</ref> It was "written before platforms such as [[w:Facebook|Facebook]], [[w:YouTube|YouTube]] and [[w:X (social network)|Twitter]] existed" -- written while [[w:Google|Google]] was a research project by [[w:Stanford University|Stanford]] [[w:Doctor of Philosophy|PhD]] students [[w:Larry Page|Larry Page]] and [[w:Sergey Brin|Sergey Brin]]. Section 230 includes, "No provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider."<ref><!--47 U.S. Code § 230 - Protection for private blocking and screening of offensive material-->{{cite Q|Q139570261}}</ref> Eisenstat says that it's time to revisit Section 230, to demand accountability where Internet companies promote or suppress information based on the content while protecting web freedom otherwise. This is similar to the [[Dean Baker on Internet companies threatening democracy internationally and how to fix that|recommendations of]] [[w:Dean Baker|Dean Baker]] that when Internet companies make money by promoting information differentially based on content, they should be liable as are legacy media under the US Supreme Court decision in ''[[w:New York Times Co. v. Sullivan|NYT v. Sullivan]]'' (1964). In other cases, they should be treated as [[w:Common carrier|common carrier]]s like telephone companies. === 2024: Tech platforms and political violence === More recently, Eisenstat et al. (2024a, b) are insisting that, "Tech Platforms Must Do More to Avoid Contributing to Potential Political Violence". ''The New York Times'' had reported that, "a steady undercurrent of violence and physical risk has become a new normal," particularly targeting public officials and democratic institutions. A survey from the Brennan Center found that 38% of election officials have experienced violent threats. They attributed these threats primarily to tech platforms and gave seven recommendations in four themes "congruent with any number of papers that academics and civil society leaders have published over the years." They said that platforms * must develop robust standards for threat assessment and engage in scenario planning, crisis training, and engagement with external stakeholders, with as much transparency as possible. * should enforce clear and actionable content moderation policies that address election integrity. * should enforce their rules uniformly, not exempting politicians and other political influencers. * must clearly explain important content moderation decisions, ensuring transparency especially when it comes to high profile accounts. They hope that increasing demands for accountability will prompt platforms to act more responsibly and prioritize the risk of political violence both in the United States and abroad. == Highlights == :''These excerpts are rushed, lightly edited for readability, and may not be in final form. The ultimate authority on what was said is the accompanying video.'' ===Most important issues === When asked about the most important things she wanted to communicate to this audience, Eisenstat replied, {{quote| There's been a debate for a number of years now on whether or not or how social media companies and online platforms are affecting our democracy, whether or not they're contributing to the rise in extremism, to threats to our elections, to democratic backsliding. These have been really important questions we've been interrogating for a number of years now. I think we've really arrived at a tipping point now, especially with some of the cases that we have seen happening in this space recently, that really show that some of the things that many of us have been saying for years are really starting to be proven, both by the actions and statements of some of the leaders of these companies themselves, or some of the documents that are showing up in court cases now. But I like to start by debunking some of the myths that surround these conversations. No, I am ''not'' saying that social media is the end all, be all cause of all of our grievances, and that democracy would be a perfect thriving thing if not for social media. I have never said that. That is not actually the point of the conversation. The question is: What role have these companies been playing, whether it's undermining elections, perhaps bringing more extremist fringe views to the mainstream and contributing to radicalization of certain people and populations and also as tools for some authoritarian regimes and leaders to truly influence not just the space in which we make sense of our information and in which we engage, both in political debate and democracy and all of it, but fundamentally, what effect are they also having on our safety, our public health, all of these issues? And so I think, you know, we're at a real tipping point where what was long viewed as some activists screaming from a mountaintop, some academics proving things through their scientific rigor, some journalists exposing things. I think we're actually at the point now where enough of the public has understood that these issues really matter, and so let's figure out how to course correct and hopefully fix some of them.}} ===Recommendations=== Graves then asked for her recommended course corrections. She replied, {{quote| We have allowed a very small handful of companies and tech leaders to have an unimaginable amount of control over how information flows, how political campaigning is communicated, how we are actually making sense of the information that underpins a healthy democracy. We have allowed that to be controlled by such a small handful of people. The irony is the original promise of the Internet was to create a much more open system, where the traditional small set of gatekeepers would be disrupted. ... I love the idea of democratizing both access to information and access to be the voices of issues. All of these things, all of these aspirations, were wonderful ideas. But let's be very clear, that is not how it is shaped up. Once a very small handful of people figured out how to both dominate this industry, scale their ideas recklessly, ensure that they could do so with all the legal protections, more than any other industry has ever been granted in place and with no accountability for the outcomes of their actions. There's no one silver bullet. ... The public needs to understand how these technologies are affecting them. Because even let's say you wanted legal and legislative changes, which I do, ... you need a constituency that believes that that change has to happen to pressure their lawmakers to actually undertake that process of fixing some of these issues. There's public education of really helping people understand, and I think that we've made some really great strides in that. If you just look at these recent court cases, more and more of the public -- they don't need to understand how an algorithm works. ... They just need to understand there is something that is not working here. I've seen enough to know I don't like how it's addicting my child or I don't like how it's making conversations so extreme that nobody feels safe to disagree with anyone anymore. I don't like how it's allowing foreign state actors to intervene in our elections in a way that was never so easy and, frankly, cheap in the past. They only need to understand that they don't like that and then say that something has to change. They don't have to be the ones to figure out exactly what that change is. And then it's on lawmakers. It's on courts, but also public pressure to the companies. ...}} === Migrating from for-profit to non-profit social media and Internet companies? === Graves then asked if she had suggestions about how to migrate from for-profit to non-profit social media and Internet companies? She replied, {{quote| It is really challenging right now. I want to be clear, I still use these companies. I would be a hypocrite if my takeaway was to tell everybody to get off of [[w:Instagram|Instagram]], [[w:TikTok|TikTok]], [[w:Facebook|Facebook]], whatever platform people are using. ... I don't want to imply that I think everybody needs to get off all of these platforms. At the end of the day, it's very hard to put the toothpaste back in the tube. These companies are part of every ounce of our being. I'll give you an example. A man I know around 57 years old never joined Instagram. Never used it. And then his child went off to college, and the parents group around all of the freshmen that were all in a group together created a group on Instagram to communicate with each other about their kids' experience and whatnot. And that person at 57 years old had to join Instagram if he wanted to be part of the parents group for his kid that just went off to school. I hate that. I wish they would have figured out a different way to create a parents group. But at the end of the day, telling people "You just need to get off these platforms" is a bit of an unfair fight, when these platforms are so ubiquitous and such a part of our everyday life. That said, people can understand how to use it in a more healthy way. ... I don't see a nonprofit social media space growing to the scale of something like [[w:Meta Platforms|Meta]] to have the [[w:Network effect|network effects]] of basically engaging almost everybody on the planet. ... If you look at [[w:Bluesky|Bluesky]] as the answer to '''[[w:X (social network)|X]]''', that's not really the answer to what you're talking about. That's still a very niche community. ... I would just like to get to the point where there's enough understanding that the status quo is not okay, and that we get to figure out how to differentiate product safety from this sort of false narrative that every single thing about a social media company is just about [[w:Freedom of speech|free speech]], and therefore it's untouchable. Hopefully, some of these recent cases have started to prove that there are real business decisions, deceptive practices, design features that are not necessarily about content, but that cause real harm in the world. These are the things we need to start grappling with, as opposed to telling everybody how to just get off the platforms. I would love to give you a recipe for how to rely more on nonprofit social media. I hope that happens someday, because at the end of the day, as long as these companies entire existence is to make money, and the only way they can truly believe they're going to make money is through this [[w:Surveillance capitalism|surveillance advertising business model]]. These issues are going to be very hard to solve, but I don't think you're going to find the nonprofit platforms catching up yet.}} ===Frances Haugen === Graves noted that he had interviewed [[Facebook whistleblower Frances Haugen says|Facebook whistleblower Francis Haugen in 2024]], who said, {{quote| The shortest path to a click is anger or hate.}} Graves asked for Eisenstat's thoughts on that. She replied that Haugen was referring to Meta's business model: {{quote| When a social media company's business model is predicated on being able to sell you personalized, targeted ads, they want to keep you on the platform as long as humanly possible, so they can [[Wiktionary:hoover|hoover]] up as much of your data as possible so they can sell this idea to an advertiser. ... For example, they know exactly which sneaker you're going to click on, as opposed to just sending that ad to like everybody on the platform. That doesn't sound so harmful. Cool: Maybe I'll get an ad for something that's interesting to me. The point about the anger and the emotion, which is something actually I really dug into in my TED Talk in 2020, ... that algorithm is coded with a goal in mind. Let's be very clear, it is a human being who is making a decision when designing that algorithm. It is not some mysterious thing that created itself. ... This is not something unique to social media. I spent the first half of my career in the field, on the ground, before social media existed. I was one of our government's top counter extremism officials. I was working with communities susceptible to extremist messaging in the early 2000s to help figure out how to inoculate them from being exploited by extremists who were going to prey on those vulnerabilities to then radicalize them in the future. And what we're seeing online is the same exact thing but at a much huger scale. The algorithms know what is going to keep you engaged. And we all know that's going to be emotional content. We all know that's usually going to be something that gets your blood racing. So it's usually going to be something gets you really upset, really angry, really outraged. And that's what's going to keep you going and engaging and sharing and commenting. They're not doing that because they care about that content. They're doing that because the more you share, click, engage, the more they're able to sell you and your data and your behavioral profile to an advertiser. ... That is fundamentally the problem with this business model. It's why all the [[w:Externality|externalities]] are what's really concerning to me. I don't know that Mark Zuckerberg purposely said ever. -- I doubt he did -- "I want to make sure that more [[w:QAnon|QAnon]] content is recommended to people." Or, "I want to make sure that more and more people are watching these misogynistic content creators talking about how to do terrible things to women." ... There is enough evidence that that is exactly what his algorithms have been incentivizing, and because it has been incentivizing that content, there is a real world consequence of taking what was once more fringe and making it more and more mainstream. And what the most important thing to understand is what happens online has real consequences offline.}} === Externalities === Graves noted that Eisenstat mentioned [[w:Externality|externalities]] and asked if she had suggestions about internalizing those externalities? She replied, {{quote| "Some of them fall into areas that unfortunately are harder to solve because they're not actually illegal, but they are causing real harm. There are different categories. I look a lot at how these platforms are helping to fuel things like political violence, extremism, radicalization -- things that are, I think many would agree, quite harmful to our democracy and our society. Again, repeating what I said earlier, I'm not saying social media is the end all, be all singular reason that these things are happening. But as others have said (I am not alone in this), they are certainly the gasoline being poured on the fire. ... Some of the documents that Francis exposed are really important in proving some of these points. ... There was an article written called "Carol's Journey to QAnon".<ref>Bidar et al. (2021).</ref> ... It was based on Facebook's own internal research at the time. It showed that Facebook internal researchers had set up this account, named her Carol, made her a mom from, I think, like the Midwest somewhere, had her start to follow a few things online, including, I think, a few politicians. But it didn't start with, "I am following QAnon" and all these crazy like right wing conspiracies. And it showed that within a very short period of time, the recommendation engines were recommending her QAnon content. We've replicated studies like that outside of Facebook. We did a study called something like the amplification of [[w:antisemitism|antisemitism]] and hate.<ref>Center for Technology & Society (2023).</ref> It also showed that the recommendation engines themselves were recommending children, teenagers who weren't even searching for conspiracy theories or antisemitic or other kinds of hate filled content, were recommending these things to them. But the reason I bring up the documents that Francis exposed is that proves that the company knew it. ... They knew these things were happening. That's a very critical point ... going back to the idea of a business model that does end up incentivizing the most extreme and salacious content. ... I think that "Carol's Journey to AQnon" is the perfect example. We started looking also at like the profiles of some of the people who commit mass violence in the United States. ... It has been skewing more and more towards young men or committing acts of political violence. I'm not going to sit here and say every single one that's ever happened. But if you look at the profile online of a lot of these people ... are spending a lot of time online in these conspiracy theory sort of rabbit holes ... . After the [[w:January 6 United States Capitol attack|January 6, 2021, insurrection on the Capitol]], you started to look at the online activity of certain individuals that were involved and implicated. You can see it. You can see that they were going more and more into very extreme content, reposting some very harmful conspiracy theories. ... Whether it's '''[[w:X (social network)|X]]''', whether it's [[w:TikTok|TikTok]], whether it's [[w:Instagram|Instagram]], I get that they are not personally responsible for the [[w:White supremacy|White supremacist]] or [[w:Neo-Nazism|Neo-Nazi]] out there who wants to spread hate. But I cannot accept that they bear no responsibility for how their own engines that they have designed not only amplify that, but actually connect people to it. Actually recommend it to children. ... Actually recommend a 57 year old predator online. "Oh, these are your likes. Here's a 13 year old girl you might want to connect with." And, yes, that has been proven to happen. Both the investigation that the New Mexico Attorney General did<ref>Lee (2026).</ref> and some other independent civil society and academics have done research in this space showing that the recommendation engines connect predators with children. These are the things that, to me, are inexcusable, that we allow companies to do with absolutely no repercussions.}} Graves interrupted, "No: There are big repercussions. They make money doing it." Eisenstat agreed, {{quote| Correct, and those are the things that we need to change. ... A lot of the work that I'm involved in right now, or have been for years, is really trying to disentangle this idea of what about what online really is speech, and I believe in some of the core spirit of this original law from 1996 called [[w:Section 230|Section 230]], which, at its core, preemptively immunizes these platforms for the speech of their users ... while also immunizing them so that they can engage in content moderation. ... That second part people forget about a lot. ... What we've been trying to do for years ... are disentangling what is truly product design that's not actually about somebody else's speech, but is about trying to elicit a particular behavior from what is third party speech so that everything doesn't get thrown out before even getting to see the light of day in court. And so that is why these two cases, Los Angeles<ref>Allyn (2026).</ref> and New Mexico,<ref name=NM/> these two big cases against Meta and Los Angeles was also against Google. These were the first two cases that actually went to a jury, because for so many years, they've been preemptively immunized by Section 230 and what was different in these cases, and you can read some of our work on this. We filed an amicus brief for the big MDL, the multi district litigation.<ref>Eisenstat and Murray (2025).</ref> We've written a lot about these cases. Some of our research underpinned some of it ... showing that these are products ... using computer science and technological research to prove that some of the products are designed 100% to have nothing to do with content itself, but to elicit a behavior. You can just read their patents, which is what we did. If you read our amicus brief, we did a lot of patent analysis. If you read their patents behind things like infinite scroll, or behind things like their intermittent reward, variable rewards, they patent this technology. They're very clear of what goal they are trying to achieve with it. Regardless of the content, those design features, those technologies, if they are, in the end, contributing to an illegal activity or to harm, that's what we should be addressing. I might hate some of the racist, homophobic, antisemitic speech that's happening online. That's not the core of what I'm trying to go after. ... Even if I hate it, it's free speech, it's [[w:First Amendment to the United States Constitution|First Amendment]] protected. It's part of what makes us an open society, But how a company itself is designing its tools to keep us on the platform, to elicit a certain behavior, to allow people to even monetize the worst of the worst. And then what harm is that creating? That's the important question.}} === Can Zuckerberg be prosecuted for perjury? === Graves noted that Zuckerberg testified in one of these trials and asked if he could be prosecuted for [[w:Perjury|perjury]]? Eisenstat replied, {{quote| That's an interesting question. ... I'm not a lawyer, so I don't know the exact answer to that. I will say that for years, we have heard, especially senior executives from Meta lie about what they know about their own products. We've heard it in congressional testimonies. ... I wasn't at the trial in Los Angeles. I don't know whether he lied or not on the stand ... . Part of why it's so important for a case like this to go to trial is because ... then you get to go into [[w:Discovery (law)|discovery]]. And what happens during discovery? You get a bunch of documents from internal communications. And the internal communications are showing exactly what they knew and what they decided to do with what they knew. And my understanding from these cases, and part of the reason the juries returned the verdicts they did, was it was proven very clearly where they keep lying about what they knew, where they keep lying about the fact that they knew their products are harming children or other issues involved there, and whether or not they decided to do anything about it. Whether he can be held for perjury, I don't know. ... I don't know if he actually lied on the stand in Los Angeles. I have heard multiple Facebook senior executives say untrue things, both in the media and in congressional hearings, but I'm not sure about in the case itself.}} === In sum === Graves then noted that we are about out of time and asked for final words for the audience. Eisenstat replied, {{quote| For parents right now, it can feel very overwhelming, because you keep getting told that social media is the most terrible thing in the world, and predators are going to stalk your children, and it's going to create terrorists around every corner. I'm not saying that's the case. I do think it can be quite dangerous, and especially for parents. They really need to get to understand the platform. Have an open conversation with their children about how they're using it. Explain to them the healthy ways to use it. Engage as a parent with your child's experience online. That said a lot of adults aren't using it in a healthy way either. ... Not everything that happens on social media is terrible. It's not. I use it still. Government's job, whether it's regulators, whether it's courts, whether it's legislators, their job is to protect the vulnerable from illegal activity, from exploitation, while hopefully also allowing innovation to thrive. ... The amount of money and power that is at stake here is unprecedented in US history. A lot of people don't understand why it has taken so long. I've been screaming about this since I left the company in 2018 and I decided to go public as a whistleblower and speak about what I saw happening there. People were speaking out before I did, and people continue to take really serious risks to try to expose what is happening in these companies. But the amount of money and power at stake is why it is so hard to find the solutions. There are so many constituents yelling at legislators, "If you do this, you're going to break the whole internet. If you do that, like the world will cease to exist." But I would just ask people to keep supporting those who are truly doing the work. It is a long battle, but I think we are starting to see real success. The ultimate goal is not to shut down every social media company. The ultimate goal is to figure out what a safer online experience looks like and what accountability looks like when something unsafe happens.}} == The need for media reform to improve democracy == This article is part of [[:category:Media reform to improve democracy]].

Athena problem is: Give a [[:w:Natural number|natural number]] ''b'' > 1, find the [[:w:Set (mathematics)|set]] of the [[:w:Minimal element|minimal element]]s of the set of the "[[:w:Prime number|prime number]] [[:w:Greater than|>]] ''b''" [[:w:Numerical digit|digit]] [[:w:String (computer science)|string]]s in the [[:w:Positional numeral system|positional numeral system]] with [[:w:Radix|base]] ''b'' for the [[:w:Subsequence|subsequence]] [[:w:Partially ordered set|ordering]]. (A string ''x'' is a subsequence of another string ''y'', if ''x'' can be obtained from ''y'' by deleting zero or more of the [[:w:Character (computing)|character]]s in ''y''. For example, 514 is a subsequence of 352148, "string" is a subsequence of "meistersinger". In contrast, 758 is not a subsequence of 378259, "abc" is not a subsequence of "cbacacba", since the characters must be in the same order) (Unlike [[:w:Substring|substring]], subsequence is not required to occupy consecutive positions within the original sequences) Using [[:w:Formal language theory|formal language theory]] terminology, Athena problem is finding the [[:w:Set (mathematics)|set]] of the [[:w:Minimal element|minimal element]]s of the [[:w:Formal language|language]] of base-''b'' [[:w:Representation (mathematics)|representation]]s of the [[:w:Prime number|prime number]]s [[:w:Greater than|>]] ''b'' (which is a set of [[:w:String (computer science)|string]]s of [[:w:Symbol|symbol]]s over the [[:w:Alphabet (formal languages)|alphabet]] ''Σ''<sub>''b''</sub> := {0, 1, ..., ''b''−1}), under the subsequence ordering (i.e. the [[:w:Binary relation|binary relation]] "is a subsequence of", which is a [[:w:Partially ordered set|partial ordering]]), for a given natural number ''b'' > 1.

Shrinking the family ''x''{''Y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''Y'' is a set of digits in base ''b'') * If ''y'' ∈ ''Y'' and the string ''xyyz'' represents a prime > ''b'' in base ''b'' (in this case, add this prime to the list) or has a subsequence which represents a prime > ''b'' in base ''b'', then ''x''{''Y''}''z'' can be replaced with ''x''{''Y'' \ ''y''}''z'' ∪ ''x''{''Y'' \ ''y''}''y''{''Y'' \ ''y''}''z''. * If ''y''<sub>1</sub> ∈ ''Y'' and ''y''<sub>2</sub> ∈ ''Y'' and ''y''<sub>1</sub> ≠ ''y''<sub>2</sub> and the string ''xy''<sub>1</sub>''y''<sub>2</sub>''z'' represents a prime > ''b'' in base ''b'' (in this case, add this prime to the list) or has a subsequence which represents a prime > ''b'' in base ''b'', then ''x''{''Y''}''z'' can be replaced with ''x''{''Y'' \ ''y''<sub>1</sub>}{''Y'' \ ''y''<sub>2</sub>}''z''. * If ''y''<sub>1</sub> ∈ ''Y'' and ''y''<sub>2</sub> ∈ ''Y'' and ''y''<sub>1</sub> ≠ ''y''<sub>2</sub> and both the strings ''xy''<sub>1</sub>''y''<sub>2</sub>''z'' and ''xy''<sub>2</sub>''y''<sub>1</sub>''z'' represent a prime > ''b'' in base ''b'' (in this case, add this prime to the list) or have a subsequence which represents a prime > ''b'' in base ''b'', then ''x''{''Y''}''z'' can be replaced with ''x''{''Y'' \ ''y''<sub>1</sub>}''z'' ∪ ''x''{''Y'' \ ''y''<sub>2</sub>}''z''. e.g. in decimal (base ''b'' = 10): * 2221 is a prime > 10, thus the family 2{0,2}1 splits into the two families 2{0}1 and 2{0}2{0}1. * 227 is a prime > 10, and it is a subsequence of 5227, thus the family 5{0,2}7 splits into the two families 5{0}7 and 5{0}2{0}7. * 449 is a prime > 10, and it is a subsequence of 6449, thus the family 6{0,3,4,6,9}9 splits into the two families 6{0,3,6,9}9 and 6{0,3,6,9}4{0,3,6,9}9. * Both 5051 and 5501 are primes > 10, thus the family 5{0,5}1 splits into the two families 5{0}1 and 5{5}1 = {5}1. * 8501 is a prime > 10, thus the family 8{0,5}1 splits into the family 8{0}{5}1. * 887 is a prime > 10, and it is a subsequence of 2887, also 2087 is a prime > 10, thus the family 2{0,8}7 splits into the two families 2{0}7 and 28{0}7. * 349 and 449 are primes > 10, and they are subsequences of 9349 and 9449, respectively, also 9049, 9649, 9949 are primes > 10, thus the family 9{0,3,4,6,9}9 splits into the two families 9{0,3,6,9}9 and 94{0,3,6,9}9. * 251, 281, 521, 821, 881 are primes > 10, and they are subsequences of 9251, 9281, 9521, 9821, 9881, respectively, also 9001, 9221, 9551, 9851 are primes > 10, thus the family 9{0,2,5,8}1 splits into the numbers {91, 901, 921, 951, 981, 9021, 9051, 9081, 9201, 9501, 9581, 9801, 90581, 95081, 95801}. If the methods we have discussed cannot be used to rule out or shrink ''x''{''Y''}''z'' where ''Y'' = {''y''<sub>1</sub>, ''y''<sub>2</sub>, ..., ''y''<sub>''n''</sub>}, then we can replace ''x''{''Y''}''z'' by ''xy''<sub>1</sub>{''Y''}''z'' ∪ ''xy''<sub>2</sub>{''Y''}''z'' ∪ ... ∪ ''xy''<sub>''n''</sub>{''Y''}''z'' and re-run the methods on this new language. If all remain families are linear families (i.e. of the form ''x''{''y''}''z'', where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''y'' is a digit in base ''b''), then we search the smallest (probable) primes in these families and add these primes to the list. e.g. in decimal (base ''b'' = 10): * The smallest prime in the family 5{0}27 is 5000000000000000000000000000027. * The smallest prime in the family {5}1 is 555555555551. * The smallest prime in the family 8{5}1 is 8555555555555555555551, but 8555555555555555555551 is not a minimal element since 555555555551 is a subsequence of 8555555555555555555551. There is no guarantee that the techniques discussed will ever terminate, but in practice they often do. They are able to determine the set of the minimal elements in base ''b'' for 2 ≤ ''b'' ≤ 16 and ''b'' = 18, 20, 22, 24, 30. The bases ''b'' = 17, 19, 21, 23, 25 ≤ ''b'' ≤ 29, 31 ≤ ''b'' ≤ 36 are solved with the exception of 771 families of the form ''x''{''y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''y'' is a digit in base ''b''). The following is a "[[:w:Semi-algorithm|semi-algorithm]]" that is guaranteed to solve the Athena problem for a given base ''b'', but it is not so easy to implement: # ''M'' = ''[[:w:Empty string|∅]]'' # while (''L'' ≠ ''∅'') do # choose ''x'', a shortest string in ''L'' # ''M'' := ''M'' ∪ {''x''} # ''L'' := ''L'' − ''sup''({''x''}) In practice, for arbitrary ''L'', we cannot feasibly carry out step 5. Instead, we work with ''L''&#39;, some regular overapproximation to ''L'', until we can show ''L''&#39; = ''∅'' (which implies ''L'' = ''∅''). In practice, ''L''&#39; is usually chosen to be a finite [[:w:Union (set theory)|union]] of sets of the form ''L''<sub>1</sub>{''L''<sub>2</sub>}''L''<sub>3</sub>, where each of ''L''<sub>1</sub>, ''L''<sub>2</sub>, ''L''<sub>3</sub> is finite. In the case we consider in this project, we then have to determine whether such a family contains a prime or not. Thus, Athena problem in bases ''b'' around 500 may be [[:w:NP-complete|NP-complete]] or [[:w:NP-hard|NP-hard]], or an [[:w:Undecidable problem|undecidable problem]], or an example of [[:w:Gödel's incompleteness theorems|Gödel's incompleteness theorems]] (like the [[:w:Continuum hypothesis|continuum hypothesis]] and the [[:w:Halting problem|halting problem]]). To solve the Athena problem, we need to determine whether a given family contains a prime. In practice, if family ''x''{''Y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''Y'' is a set of digits in base ''b'') could not be ruled out as only containing composites and ''Y'' contains two or more digits, then a relatively small prime > ''b'' could always be found in this family. Intuitively, this is because there are a large number of small strings in such a family, and at least one is likely to be prime (e.g. there are 2<sup>''n''−2</sup> strings of length ''n'' in the family 1{3,7}9, and there are over a thousand strings of length 12 in the family 1{3,7}9, thus it is very impossible that these numbers are all composite). In the case ''Y'' contains only one digit, this family is of the form ''x''{''y''}''z'', and there is only a single string of each length > (the length of ''x'' + the length of ''z''), and it is not known if the following [[:w:Decision problem|decision problem]] is recursively solvable (just like [[:w:Sierpiński number|Sierpiński problem]] and [[:w:Riesel number|Riesel problem]], Sierpiński problem and Riesel problem can be generalized to other bases ''b'', in fact, Athena problem in base ''b'' covers the Sierpiński problem in base ''b'' and the Riesel problem in base ''b'' with ''k'' < ''b'', i.e. finding the smallest prime of the form ''k''×''b''<sup>''n''</sup>+1 and ''k''×''b''<sup>''n''</sup>−1 (or prove such prime does not exist) with ''k'' < ''b'', since the smallest prime of the form ''k''×''b''<sup>''n''</sup>+1 and ''k''×''b''<sup>''n''</sup>−1 (if exists) must be a minimal element in base ''b''): Problem: Given strings ''x'', ''z'' (may be empty), a digit ''y'', and a base ''b'' (''x'' does not [[:w:Leading zero|start with the digit 0]], ''z'' ends with a digit which [[:w:Coprime integers|coprime]] to ''b'', ''y'' is not 0 if ''x'' is empty, ''y'' is coprime to ''b'' if ''z'' is empty), does there exist a prime number whose base-''b'' expansion is of the form ''xy''<sub>''n''</sub>''z'' for some ''n'' ≥ 0? Some families can be ruled out to contain no prime > ''b'' by [[:w:Covering set|covering congruence]], [[:w:Factorization of polynomials|algebraic factorization]] (e.g. [[:w:Difference of two squares|difference of two squares]], [[:w:Sum of two cubes|sum of two cubes]], [[:w:Sophie Germain's identity|Sophie Germain's identity of ''x''<sup>4</sup>+4×''y''<sup>4</sup>]]), or combine of them, e.g. * The base 9 family 2{7}: Always divisible by 2 or 5 * The base 16 family {8}F: Always divisible by 3, 7, or 13 * The base 21 family {7}D: Always divisible by 2, 13, or 17 * The base 23 family {D}GA: Always divisible by 2, 5, 7, 37, or 79 * The base 9 family 3{8}: Can be written as 4×9<sup>''n''</sup>−1 and can be factored as (2×3<sup>''n''</sup>−1) × (2×3<sup>''n''</sup>+1) * The base 8 family 1{0}1: Can be written as 8<sup>''n''</sup>+1 and can be factored as (2<sup>''n''</sup>+1) × (4<sup>''n''</sup>−2<sup>''n''</sup>+1) * The base 16 family {4}1: Can be written as (4×16<sup>''n''</sup>−49)/15 and can be factored as (2×3<sup>''n''</sup>−7) × (2×3<sup>''n''</sup>+7) / 15 * The base 16 family {C}D: Can be written as (4×16<sup>''n''</sup>+1)/5 and can be factored as (2×4<sup>''n''</sup>−2×2<sup>''n''</sup>+1) × (2×4<sup>''n''</sup>+2×2<sup>''n''</sup>+1) / 5 * The base 14 family 8{D}: Can be written as 9×14<sup>''n''</sup>−1, it is divisible by 5 if ''n'' is odd and can be factored as (3×14<sup>''n''/2</sup>−1) × (3×14<sup>''n''/2</sup>+1) if ''n'' is even * The base 12 family {B}9B: Can be written as 12<sup>''n''</sup>−25, it is divisible by 13 if ''n'' is odd and can be factored as (12<sup>''n''/2</sup>−5) × (12<sup>''n''/2</sup>+5) if ''n'' is even * The base 17 family 1{9}: Can be written as (25×17<sup>''n''</sup>−9)/16, it is divisible by 2 if ''n'' is odd and can be factored as (5×17<sup>''n''/2</sup>−3) × (5×17<sup>''n''/2</sup>+3) / 16 if ''n'' is even * The base 19 family 1{6}: Can be written as (4×19<sup>''n''</sup>−1)/3, it is divisible by 5 if ''n'' is odd and can be factored as (2×19<sup>''n''/2</sup>−1) × (2×19<sup>''n''/2</sup>+1) / 3 if ''n'' is even By the [[:w:Prime number theorem|prime number theorem]], the [[:w:Probability|chance]] that a [[:w:Random number|random]] ''n''-digit base ''b'' number is prime is [[:w:Asymptotic analysis|approximately]] 1/''n'' (more accurately, the chance is approximately 1/(''n''×''ln''(''b'')), where ''ln'' is the [[:w:Natural logarithm|natural logarithm]]). If one conjectures the numbers ''x''{''y''}''z'' behave similarly (i.e. the numbers ''x''{''y''}''z'' is a [[:w:Pseudorandomness|pseudorandom sequence]]) you would expect [[:w:Harmonic_series (mathematics)|1/1 + 1/2 + 1/3 + 1/4 + ... = ∞]] primes of the form ''x''{''y''}''z'' (of course, this does not always happen, since some ''x''{''y''}''z'' families can be ruled out to contain no prime > ''b'' (by covering congruence, algebraic factorization, or combine of them), but it is at least a reasonable conjecture in the absence of evidence to the contrary. Hence, the [[:w:Heuristic argument|heuristic argument]] suggests there are always infinitely many primes in family ''x''{''y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''y'' is a digit in base ''b'') if it cannot be ruled out to contain no prime or only contain finitely many primes, by covering congruence, algebraic factorization, or combine of them. However, some families ''x''{''y''}''z'' could not be proven to contain no primes > ''b'' (by covering congruence, algebraic factorization, or combine of them) but no primes > ''b'' could be found in the family, even after searching through numbers with over 100000 digits. In such a case, the only way to proceed is to test the primality of larger and larger numbers of such form and hope a prime is eventually discovered. e.g. the smallest (probable) prime in the family A{3}A in base ''b'' = 13 is A3<sub>592197</sub>A, which written in decimal contains 659677 digits (it is only probable prime, i.e. not definitely prime). All numbers are written in base ''b'', [[:w:Senary#Base 36 as senary compression|using A to Z to represent digit values 10 to 35]], "{}" means repeating, e.g. family 12{3}45 means the sequence {1245, 12345, 123345, 1233345, 12333345, 123333345, ...} (where the members are expressed as base ''b'' strings), subscripts are used to indicate repetitions of digits, e.g. 123<sub>4</sub>567 means 123333567 (all subscripts are written in decimal).

problem in decimal (base ''b'' = 10) == '''Bold''' for the minimal elements, ''x'' ◁ ''y'' means ''x'' is a subsequence of ''y''. Assume ''p'' is a prime > 10, and the last digit of ''p'' must lie in {1,3,7,9}. Case 1: ''p'' ends with 1. In this case we can write ''p'' = ''x''1. If ''x'' contains 1, 3, 4, 6, or 7, then (respectively) '''11''' ◁ ''p'', '''31''' ◁ ''p'', '''41''' ◁ ''p'', '''61''' ◁ ''p'', or '''71''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 2, 5, 8, or 9. Case 1.1: ''p'' begins with 2. In this case we can write ''p'' = 2''y''1. If 5 ◁ ''y'', then '''251''' ◁ ''p''. If 8 ◁ ''y'', then '''281''' ◁ ''p''. If 9 ◁ ''y'', then 29 ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 2. If 22 ◁ ''y'', then '''2221''' ◁ ''p''. Hence we may assume ''y'' contains zero or one 2's. If ''y'' contains no 2's, then ''p'' ∈ 2{0}1. But then, since the sum of the digits of ''p'' is 3, ''p'' is divisible by 3, so ''p'' cannot be prime. If ''y'' contains exactly one 2, then we can write ''p'' = 2''z''2''w''1, where ''z'',''w'' ∈ {0}. If 0 ◁ ''z'' and 0 ◁ ''w'', then '''20201''' ◁ ''p''. Hence we may assume either ''z'' or ''w'' is empty. If ''z'' is empty, then ''p'' ∈ 22{0}1, and the smallest prime ''p'' ∈ 22{0}1 is '''22000001'''. If ''w'' is empty, then ''p'' ∈ 2{0}21, and the smallest prime ''p'' ∈ 2{0}21 is '''20021'''. Case 1.2: ''p'' begins with 5. In this case we can write ''p'' = 5''y''1. If 2 ◁ ''y'', then '''521''' ◁ ''p''. If 9 ◁ ''y'', then 59 ◁ ''p''. Hence we may assume all digits of ''y'' are 0, 5, or 8. If 05 ◁ ''y'', then '''5051''' ◁ ''p''. If 08 ◁ ''y'', then '''5081''' ◁ ''p''. If 50 ◁ ''y'', then '''5501''' ◁ ''p''. If 58 ◁ ''y'', then '''5581''' ◁ ''p''. If 80 ◁ ''y'', then '''5801''' ◁ ''p''. If 85 ◁ ''y'', then '''5851''' ◁ ''p''. Hence we may assume ''y'' ∈ {0} ∪ {5} ∪ {8}. If ''y'' ∈ {0}, then ''p'' ∈ 5{0}1. But then, since the sum of the digits of ''p'' is 6, ''p'' is divisible by 3, so ''p'' cannot be prime. If ''y'' ∈ {5}, then ''p'' ∈ 5{5}1, and the smallest prime ''p'' ∈ 5{5}1 is '''555555555551'''. If ''y'' ∈ {8}, since if 88 ◁ ''y'', then 881 ◁ ''p'', hence we may assume ''y'' ∈ {''𝜆'',8}, and thus ''p'' ∈ {51,581}, but 51 and 581 are both composite. Case 1.3: ''p'' begins with 8. In this case we can write p = 8''y''1. If 2 ◁ ''y'', then '''821''' ◁ ''p''. If 8 ◁ ''y'', then '''881''' ◁ ''p''. If 9 ◁ ''y'', then 89 ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 5. If 50 ◁ ''y'', then '''8501''' ◁ ''p''. Hence we may assume y ∈ {0}{5}. If 005 ◁ ''y'', then '''80051''' ◁ p. Hence we may assume y ∈ {0} ∪ {5} ∪ 0{5}. If y ∈ {0}, then ''p'' ∈ 8{0}1. But then, since the sum of the digits of ''p'' is 9, ''p'' is divisible by 3, so ''p'' cannot be prime. If y ∈ {5}, since if 55555555555 ◁ ''y'', then 555555555551 ◁ ''p'', hence we may assume ''y'' ∈ {''𝜆'', 5, 55, 555, 5555, 55555, 555555, 5555555, 55555555, 555555555, 5555555555}, and thus ''p'' ∈ {81, 851, 8551, 85551, 855551, 8555551, 85555551, 855555551, 8555555551, 85555555551, 855555555551}, but all of these numbers are composite. If y ∈ 0{5}, since if 55555555555 ◁ ''y'', then 555555555551 ◁ ''p'', hence we may assume ''y'' ∈ {0, 05, 055, 0555, 05555, 055555, 0555555, 05555555, 055555555, 0555555555, 05555555555}, and thus ''p'' ∈ {801, 8051, 80551, 805551, 8055551, 80555551, 805555551, 8055555551, 80555555551, 805555555551, 8055555555551}, and of these numbers only 80555551 and 8055555551 are primes, but 80555551 ◁ 8055555551, thus only '''80555551''' is a minimal element. Case 1.4: ''p'' begins with 9. In this case we can write p = 9''y''1. If 9 ◁ ''y'', then '''991''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0, 2, 5, or 8. If 00 ◁ ''y'', then '''9001''' ◁ ''p''. If 22 ◁ ''y'', then '''9221''' ◁ ''p''. If 55 ◁ ''y'', then '''9551''' ◁ ''p''. If 88 ◁ ''y'', then 881 ◁ ''p''. Hence we may assume ''y'' contains at most one 0, at most one 2, at most one 5, and at most one 8. If ''y'' only contains at most one 0 and does not contain any of {2,5,8}, then ''y'' ∈ {''𝜆'',0}, and thus ''p'' ∈ {91,901}, but 91 and 901 are both composite. If ''y'' only contains at most one 0 and only one of {2,5,8}, then the sum of the digits of ''p'' is divisible by 3, ''p'' is divisible by 3, so ''p'' cannot be prime. Hence we may assume ''y'' contains at least two of {2,5,8}. If 25 ◁ ''y'', then 251 ◁ ''p''. If 28 ◁ ''y'', then 281 ◁ ''p''. If 52 ◁ ''y'', then 521 ◁ ''p''. If 82 ◁ ''y'', then 821 ◁ ''p''. Hence we may assume ''y'' contains no 2's (since if ''y'' contains 2, then ''y'' cannot contain either 5's or 8's, which is a contradiction). If 85 ◁ ''y'', then '''9851''' ◁ ''p''. Hence we may assume ''y'' ∈ {58,580,508,058}, and thus ''p'' ∈ {9581,95801,95081,90581}, and of these numbers only 95801 is prime, but 95801 is not a minimal element since 5801 ◁ 95801. Case 2: ''p'' ends with 3. In this case we can write p = ''x''3. If ''x'' contains 1, 2, 4, 5, 7, or 8, then (respectively) '''13''' ◁ ''p'', '''23''' ◁ ''p'', '''43''' ◁ ''p'', '''53''' ◁ ''p'', '''73''' ◁ ''p'', or '''83''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 3, 6, or 9, and thus all digits of ''p'' are 0, 3, 6, or 9. But then, since the digits of ''p'' all have a common factor 3, ''p'' is divisible by 3, so ''p'' cannot be prime. Case 3: ''p'' ends with 7. In this case we can write ''p'' = ''x''7. If ''x'' contains 1, 3, 4, 6, or 9, then (respectively) '''17''' ◁ ''p'', '''37''' ◁ ''p'', '''47''' ◁ ''p'', '''67''' ◁ ''p'', or '''97''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 2, 5, 7, or 8. Case 3.1: ''p'' begins with 2. In this case we can write ''p'' = 2''y''7. If 2 ◁ ''y'', then '''227''' ◁ ''p''. If 5 ◁ ''y'', then '''257''' ◁ ''p''. If 7 ◁ ''y'', then '''277''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 8. If 08 ◁ ''y'', then '''2087''' ◁ ''p''. If 88 ◁ ''y'', then 887 ◁ ''p''. Hence we may assume ''y'' ∈ {0} ∪ 8{0}. If ''y'' ∈ {0}, then ''p'' ∈ 2{0}7. But then, since the sum of the digits of ''p'' is 9, ''p'' is divisible by 3, so ''p'' cannot be prime. If y ∈ 8{0}, then ''p'' ∈ 28{0}7. But then ''p'' is divisible by 7, since for ''n'' ≥ 0 we have 7 × 40<sub>''n''</sub>1 = 280<sub>''n''</sub>7. Case 3.2: ''p'' begins with 5. In this case we can write ''p'' = 5''y''7. If 5 ◁ ''y'', then '''557''' ◁ ''p''. If 7 ◁ ''y'', then '''577''' ◁ ''p''. If 8 ◁ ''y'', then '''587''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 2. If 22 ◁ ''y'', then 227 ◁ ''p''. Hence we may assume ''y'' contains zero or one 2's. If ''y'' contains no 2's, then ''p'' ∈ 5{0}7. But then, since the sum of the digits of ''p'' is 12, ''p'' is divisible by 3, so ''p'' cannot be prime. If ''y'' contains exactly one 2, then we can write ''p'' = 5''z''2''w''7, where ''z'',''w'' ∈ {0}. If 0 ◁ ''z'' and 0 ◁ ''w'', then '''50207''' ◁ ''p''. Hence we may assume either ''z'' or ''w'' is empty. If ''z'' is empty, then ''p'' ∈ 52{0}7, and the smallest prime ''p'' ∈ 52{0}7 is '''5200007'''. If ''w'' is empty, then ''p'' ∈ 5{0}27, and the smallest prime ''p'' ∈ 5{0}27 is '''5000000000000000000000000000027'''. Case 3.3: ''p'' begins with 7. In this case we can write ''p'' = 7''y''7. If 2 ◁ ''y'', then '''727''' ◁ ''p''. If 5 ◁ ''y'', then '''757''' ◁ ''p''. If 8 ◁ ''y'', then '''787''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 7, and thus all digits of ''p'' are 0 or 7. But then, since the digits of ''p'' all have a common factor 7, ''p'' is divisible by 7, so ''p'' cannot be prime. Case 3.4: ''p'' begins with 8. In this case we can write ''p'' = 8''y''7. If 2 ◁ ''y'', then '''827''' ◁ ''p''. If 5 ◁ ''y'', then '''857''' ◁ ''p''. If 7 ◁ ''y'', then '''877''' ◁ ''p''. If 8 ◁ ''y'', then '''887''' ◁ ''p''. Hence we may assume ''y'' ∈ {0}, and thus ''p'' ∈ 8{0}7. But then, since the sum of the digits of ''p'' is 15, ''p'' is divisible by 3, so ''p'' cannot be prime. Case 4: ''p'' ends with 9. In this case we can write ''p'' = ''x''9. If ''x'' contains 1, 2, 5, 7, or 8, then (respectively) '''19''' ◁ ''p'', '''29''' ◁ ''p'', '''59''' ◁ ''p'', '''79''' ◁ ''p'', or '''89''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 3, 4, 6, or 9. If 44 ◁ ''x'', then '''449''' ◁ ''p''. Hence we may assume ''x'' contains zero or one 4's. If x contains no 4's, then all digits of ''x'' are 0, 3, 6, or 9, and thus all digits of ''p'' are 0, 3, 6, or 9. But then, since the digits of ''p'' all have a common factor 3, ''p'' is divisible by 3, so ''p'' cannot be prime. Hence we may assume that ''x'' contains exactly one 4. Case 4.1: ''p'' begins with 3. In this case we can write ''p'' = 3''y''4''z''9, where all digits of ''y'', ''z'' are 0, 3, 6, or 9. We must have '''349''' ◁ ''p''. Case 4.2: ''p'' begins with 4. In this case we can write ''p'' = 4''y''9, where all digits of ''y'' are 0, 3, 6, or 9. If 0 ◁ ''y'', then '''409''' ◁ ''p''. If 3 ◁ ''y'', then 43 ◁ ''p''. If 9 ◁ ''y'', then '''499''' ◁ ''p''. Hence we may assume ''y'' ∈ {6}, and thus ''p'' ∈ 4{6}9. But then ''p'' is divisible by 7, since for ''n'' ≥ 0 we have 7 × 6<sub>''n''</sub>7 = 46<sub>''n''</sub>9. Case 4.3: ''p'' begins with 6. In this case we can write p = 6''y''4''z''9, where all digits of ''y'', ''z'' are 0, 3, 6, or 9. If 0 ◁ ''z'', then 409 ◁ ''p''. If 3 ◁ ''z'', then 43 ◁ ''p''. If 6 ◁ ''z'', then '''6469''' ◁ ''p''. If 9 ◁ ''z'', then 499 ◁ ''p''. Hence we may assume ''z'' is empty. If 3 ◁ ''y'', then 349 ◁ ''p''. If 9 ◁ ''y'', then '''6949''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 6. If 06 ◁ ''y'', then '''60649''' ◁ ''p''. Hence we may assume ''y'' ∈ {6}{0}. If 666 ◁ ''y'', then '''666649''' ◁ ''p''. If 00000 ◁ ''y'', then '''60000049''' ◁ ''p''. Hence we may assume ''y'' ∈ {''𝜆'', 0, 00, 000, 0000, 6, 60, 600, 6000, 60000, 66, 660, 6600, 66000, 660000}, and thus ''p'' ∈ {649, 6049, 60049, 600049, 6000049, 6649, 66049, 660049, 6600049, 66000049, 66649, 666049, 6660049, 66600049, 666000049}, and of these numbers only '''66000049''' and '''66600049''' are primes. Case 4.4: ''p'' begins with 9. In this case we can write p = 9''y''4''z''9, where all digits of ''y'', ''z'' are 0, 3, 6, or 9. If 0 ◁ ''y'', then '''9049''' ◁ ''p''. If 3 ◁ ''y'', then 349 ◁ ''p''. If 6 ◁ ''y'', then '''9649''' ◁ ''p''. If 9 ◁ ''y'', then '''9949''' ◁ ''p''. Hence we may assume ''y'' is empty. If 0 ◁ ''z'', then 409 ◁ ''p''. If 3 ◁ ''z'', then 43 ◁ ''p''. If 9 ◁ ''z'', then 499 ◁ ''p''. Hence we may assume ''z'' ∈ {6}, and thus ''p'' ∈ 94{6}9, and the smallest prime ''p'' ∈ 94{6}9 is 946669.

Athena problem is: Give a [[:w:Natural number|natural number]] ''b'' > 1, find the [[:w:Set (mathematics)|set]] of the [[:w:Minimal element|minimal element]]s of the set of the "[[:w:Prime number|prime number]] [[:w:Greater than|>]] ''b''" [[:w:Numerical digit|digit]] [[:w:String (computer science)|string]]s in the [[:w:Positional numeral system|positional numeral system]] with [[:w:Radix|base]] ''b'' for the [[:w:Subsequence|subsequence]] [[:w:Partially ordered set|ordering]]. (A string ''x'' is a subsequence of another string ''y'', if ''x'' can be obtained from ''y'' by deleting zero or more of the [[:w:Character (computing)|character]]s in ''y''. For example, 514 is a subsequence of 352148, "string" is a subsequence of "meistersinger". In contrast, 758 is not a subsequence of 378259, "abc" is not a subsequence of "cbacacba", since the characters must be in the same order) (Unlike [[:w:Substring|substring]], subsequence is not required to occupy consecutive positions within the original sequences) Using [[:w:Formal language theory|formal language theory]] terminology, Athena problem is finding the [[:w:Set (mathematics)|set]] of the [[:w:Minimal element|minimal element]]s of the [[:w:Formal language|language]] of base-''b'' [[:w:Representation (mathematics)|representation]]s of the [[:w:Prime number|prime number]]s [[:w:Greater than|>]] ''b'' (which is a set of [[:w:String (computer science)|string]]s of [[:w:Symbol|symbol]]s over the [[:w:Alphabet (formal languages)|alphabet]] ''Σ''<sub>''b''</sub> := {0, 1, ..., ''b''−1}), under the subsequence ordering (i.e. the [[:w:Binary relation|binary relation]] "is a subsequence of", which is a [[:w:Partially ordered set|partial ordering]]), for a given natural number ''b'' > 1. (You can draw this ordering as [[:w:Hasse diagram|Hasse diagram]] to find all [[:w:Minimal element|minimal element]]s) By [[:w:Higman's lemma|Higman's lemma]], there are no [[:w:Infinite set|infinite]] [[:w:Antichain|antichain]]s for the subsequence ordering (i.e. the subsequence ordering is always a [[:w:Well-quasi-ordering|well quasi order]]) (i.e. under the subsequence ordering (i.e. the [[:w:Binary relation|binary relation]] "is a subsequence of", which is a [[:w:Partially ordered set|partial ordering]]), every set of pairwise incomparable (i.e. not [[:w:Comparability|comparable]]) strings is finite), thus there must be only finitely many such minimal elements. In other words, the set of such minimal elements must be a [[:w:Finite set|finite set]], e.g. in [[:w:Decimal|decimal]] (base ''b'' = 10), this set has exactly 77 [[:w:Element of a set|element]]s: {11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 227, 251, 257, 277, 281, 349, 409, 449, 499, 521, 557, 577, 587, 727, 757, 787, 821, 827, 857, 877, 881, 887, 991, 2087, 2221, 5051, 5081, 5501, 5581, 5801, 5851, 6469, 6949, 8501, 9001, 9049, 9221, 9551, 9649, 9851, 9949, 20021, 20201, 50207, 60649, 80051, 666649, 946669, 5200007, 22000001, 60000049, 66000049, 66600049, 80555551, 555555555551, 5000000000000000000000000000027}. For bases 2 ≤ ''b'' ≤ 36, Athena problem is fully solved in bases ''b'' = 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 14, 15, 18, 20, 24, and also solved in bases ''b'' = 11, 13, 16, 22, 30 if [[:w:Probable prime|probable prime]]s are allowed. For the unsolved bases ''b'' = 17, 19, 21, 23, 25, 26, 27, 28, 29, 31, 32, 34, 35, 36, Athena problem is solved (if probable primes are allowed) except 771 [[:w:Indexed family|families]] of the form ''x''{''y''}''z'' (where ''x'' and ''z'' are strings (may be [[:w:Empty string|empty]]) of digits in base ''b'', ''y'' is a digit in base ''b''), all of these 771 families contain no primes or probable primes with length ≤ 100000. == Results == These are the results of the Athena problem in bases 2 ≤ ''b'' ≤ 36 (we stop at base 36 since this base is the maximum base for which it is possible to write the numbers with the [[:w:Symbol|symbol]]s 0, 1, 2, ..., 9 and A, B, C, ..., Z (i.e. the 10 [[:w:Arabic numerals|Arabic numerals]] and the 26 [[:w:Latin script|Latin letters]]): (some large primes are only probable primes, i.e. not definitely primes, since they are too large to be [[:w:Elliptic curve primality|ECPP proved]] and [[:w:Pocklington primality test#Extensions and variants|neither ''N''−1 nor ''N''+1 can be ≥ 1/3 factored]], all of them pass the [[:w:Baillie–PSW primality test|Baillie–PSW primality test]] and the [[:w:Strong pseudoprime|strong primality test]] (i.e. the [[:w:Miller–Rabin primality test|Miller–Rabin primality test]]) with all prime bases ''p'' ≤ 61, however, all primes < 10<sup>25000</sup> for bases ''b'' = 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 18, 20, 22, 24, 26, 28, 30, 36 are definitely primes, most of them > 10<sup>299</sup> are proven primes with [[:w:Elliptic curve primality|ECPP proving]], others > 10<sup>299</sup> are proven primes with [[:w:Pocklington primality test#Extensions and variants|''N''−1 or ''N''+1 proving]]) To solve the Athena problem for a given base ''b'', we must [[:w:Computing|compute]] the element up to families of the form ''x''{''y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''y'' is a digit in base ''b'') (we call such families ''linear families''), and find the smallest prime > ''b'' in all such families. Shrinking the family ''x''{''Y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''Y'' is a set of digits in base ''b'') * If ''y'' ∈ ''Y'' and the string ''xyyz'' represents a prime > ''b'' in base ''b'' (in this case, add this prime to the list) or has a subsequence which represents a prime > ''b'' in base ''b'', then ''x''{''Y''}''z'' can be replaced with ''x''{''Y'' \ ''y''}''z'' ∪ ''x''{''Y'' \ ''y''}''y''{''Y'' \ ''y''}''z''. * If ''y''<sub>1</sub> ∈ ''Y'' and ''y''<sub>2</sub> ∈ ''Y'' and ''y''<sub>1</sub> ≠ ''y''<sub>2</sub> and the string ''xy''<sub>1</sub>''y''<sub>2</sub>''z'' represents a prime > ''b'' in base ''b'' (in this case, add this prime to the list) or has a subsequence which represents a prime > ''b'' in base ''b'', then ''x''{''Y''}''z'' can be replaced with ''x''{''Y'' \ ''y''<sub>1</sub>}{''Y'' \ ''y''<sub>2</sub>}''z''. * If ''y''<sub>1</sub> ∈ ''Y'' and ''y''<sub>2</sub> ∈ ''Y'' and ''y''<sub>1</sub> ≠ ''y''<sub>2</sub> and both the strings ''xy''<sub>1</sub>''y''<sub>2</sub>''z'' and ''xy''<sub>2</sub>''y''<sub>1</sub>''z'' represent a prime > ''b'' in base ''b'' (in this case, add this prime to the list) or have a subsequence which represents a prime > ''b'' in base ''b'', then ''x''{''Y''}''z'' can be replaced with ''x''{''Y'' \ ''y''<sub>1</sub>}''z'' ∪ ''x''{''Y'' \ ''y''<sub>2</sub>}''z''. e.g. in decimal (base ''b'' = 10): * 2221 is a prime > 10, thus the family 2{0,2}1 splits into the two families 2{0}1 and 2{0}2{0}1. * 227 is a prime > 10, and it is a subsequence of 5227, thus the family 5{0,2}7 splits into the two families 5{0}7 and 5{0}2{0}7. * 449 is a prime > 10, and it is a subsequence of 6449, thus the family 6{0,3,4,6,9}9 splits into the two families 6{0,3,6,9}9 and 6{0,3,6,9}4{0,3,6,9}9. * Both 5051 and 5501 are primes > 10, thus the family 5{0,5}1 splits into the two families 5{0}1 and 5{5}1 = {5}1. * 8501 is a prime > 10, thus the family 8{0,5}1 splits into the family 8{0}{5}1. * 887 is a prime > 10, and it is a subsequence of 2887, also 2087 is a prime > 10, thus the family 2{0,8}7 splits into the two families 2{0}7 and 28{0}7. * 349 and 449 are primes > 10, and they are subsequences of 9349 and 9449, respectively, also 9049, 9649, 9949 are primes > 10, thus the family 9{0,3,4,6,9}9 splits into the two families 9{0,3,6,9}9 and 94{0,3,6,9}9. * 251, 281, 521, 821, 881 are primes > 10, and they are subsequences of 9251, 9281, 9521, 9821, 9881, respectively, also 9001, 9221, 9551, 9851 are primes > 10, thus the family 9{0,2,5,8}1 splits into the numbers {91, 901, 921, 951, 981, 9021, 9051, 9081, 9201, 9501, 9581, 9801, 90581, 95081, 95801}. If the methods we have discussed cannot be used to rule out or shrink ''x''{''Y''}''z'' where ''Y'' = {''y''<sub>1</sub>, ''y''<sub>2</sub>, ..., ''y''<sub>''n''</sub>}, then we can replace ''x''{''Y''}''z'' by ''xy''<sub>1</sub>{''Y''}''z'' ∪ ''xy''<sub>2</sub>{''Y''}''z'' ∪ ... ∪ ''xy''<sub>''n''</sub>{''Y''}''z'' and re-run the methods on this new [[:w:Formal language|language]]. If all remain families are linear families (i.e. of the form ''x''{''y''}''z'', where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''y'' is a digit in base ''b''), then we search the smallest (probable) primes in these families and add these primes to the list. e.g. in decimal (base ''b'' = 10): * The smallest prime in the family 5{0}27 is 5000000000000000000000000000027. * The smallest prime in the family {5}1 is 555555555551. * The smallest prime in the family 8{5}1 is 8555555555555555555551, but 8555555555555555555551 is not a minimal element since 555555555551 is a subsequence of 8555555555555555555551. There is no guarantee that the techniques discussed will ever terminate, but in practice they often do. They are able to determine the set of the minimal elements in base ''b'' for 2 ≤ ''b'' ≤ 16 and ''b'' = 18, 20, 22, 24, 30. The bases ''b'' = 17, 19, 21, 23, 25 ≤ ''b'' ≤ 29, 31 ≤ ''b'' ≤ 36 are solved with the exception of 771 families of the form ''x''{''y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''y'' is a digit in base ''b''). The following is a "[[:w:Semi-algorithm|semi-algorithm]]" that is guaranteed to solve the Athena problem for a given base ''b'', but it is not so easy to implement: # ''M'' = ''[[:w:Empty string|∅]]'' # while (''L'' ≠ ''∅'') do # choose ''x'', a shortest string in ''L'' # ''M'' := ''M'' ∪ {''x''} # ''L'' := ''L'' − ''sup''({''x''}) In practice, for arbitrary ''L'', we cannot feasibly carry out step 5. Instead, we work with ''L''&#39;, some regular overapproximation to ''L'', until we can show ''L''&#39; = ''∅'' (which implies ''L'' = ''∅''). In practice, ''L''&#39; is usually chosen to be a finite [[:w:Union (set theory)|union]] of sets of the form ''L''<sub>1</sub>{''L''<sub>2</sub>}''L''<sub>3</sub>, where each of ''L''<sub>1</sub>, ''L''<sub>2</sub>, ''L''<sub>3</sub> is finite. In the case we consider in this project, we then have to determine whether such a family contains a prime or not. Thus, Athena problem in bases ''b'' around 500 may be [[:w:NP-complete|NP-complete]] or [[:w:NP-hard|NP-hard]], or an [[:w:Undecidable problem|undecidable problem]], or an example of [[:w:Gödel's incompleteness theorems|Gödel's incompleteness theorems]] (like the [[:w:Continuum hypothesis|continuum hypothesis]] and the [[:w:Halting problem|halting problem]]). To solve the Athena problem, we need to determine whether a given family contains a prime. In practice, if family ''x''{''Y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''Y'' is a set of digits in base ''b'') could not be ruled out as only containing composites and ''Y'' contains two or more digits, then a relatively small prime > ''b'' could always be found in this family. Intuitively, this is because there are a large number of small strings in such a family, and at least one is likely to be prime (e.g. there are 2<sup>''n''−2</sup> strings of length ''n'' in the family 1{3,7}9, and there are over a thousand strings of length 12 in the family 1{3,7}9, thus it is very impossible that these numbers are all composite). In the case ''Y'' contains only one digit, this family is of the form ''x''{''y''}''z'', and there is only a single string of each length > (the length of ''x'' + the length of ''z''), and it is not known if the following [[:w:Decision problem|decision problem]] is recursively solvable (just like [[:w:Sierpiński number|Sierpiński problem]] and [[:w:Riesel number|Riesel problem]], Sierpiński problem and Riesel problem can be generalized to other bases ''b'', in fact, Athena problem in base ''b'' covers the Sierpiński problem in base ''b'' and the Riesel problem in base ''b'' with ''k'' < ''b'', i.e. finding the smallest prime of the form ''k''×''b''<sup>''n''</sup>+1 and ''k''×''b''<sup>''n''</sup>−1 (or prove such prime does not exist) with ''k'' < ''b'', since the smallest prime of the form ''k''×''b''<sup>''n''</sup>+1 and ''k''×''b''<sup>''n''</sup>−1 (if exists) must be a minimal element in base ''b''): Problem: Given strings ''x'', ''z'' (may be empty), a digit ''y'', and a base ''b'' (''x'' does not [[:w:Leading zero|start with the digit 0]], ''z'' ends with a digit which [[:w:Coprime integers|coprime]] to ''b'', ''y'' is not 0 if ''x'' is empty, ''y'' is coprime to ''b'' if ''z'' is empty), does there exist a prime number whose base-''b'' expansion is of the form ''xy''<sub>''n''</sub>''z'' for some ''n'' ≥ 0? Some families can be ruled out to contain no prime > ''b'' by [[:w:Covering set|covering congruence]], [[:w:Factorization of polynomials|algebraic factorization]] (e.g. [[:w:Difference of two squares|difference of two squares]], [[:w:Sum of two cubes|sum of two cubes]], [[:w:Sophie Germain's identity|Sophie Germain's identity of ''x''<sup>4</sup>+4×''y''<sup>4</sup>]]), or combine of them, e.g. * The base 9 family 2{7}: Always divisible by 2 or 5 * The base 16 family {8}F: Always divisible by 3, 7, or 13 * The base 21 family {7}D: Always divisible by 2, 13, or 17 * The base 23 family {D}GA: Always divisible by 2, 5, 7, 37, or 79 * The base 9 family 3{8}: Can be written as 4×9<sup>''n''</sup>−1 and can be factored as (2×3<sup>''n''</sup>−1) × (2×3<sup>''n''</sup>+1) * The base 8 family 1{0}1: Can be written as 8<sup>''n''</sup>+1 and can be factored as (2<sup>''n''</sup>+1) × (4<sup>''n''</sup>−2<sup>''n''</sup>+1) * The base 16 family {4}1: Can be written as (4×16<sup>''n''</sup>−49)/15 and can be factored as (2×3<sup>''n''</sup>−7) × (2×3<sup>''n''</sup>+7) / 15 * The base 16 family {C}D: Can be written as (4×16<sup>''n''</sup>+1)/5 and can be factored as (2×4<sup>''n''</sup>−2×2<sup>''n''</sup>+1) × (2×4<sup>''n''</sup>+2×2<sup>''n''</sup>+1) / 5 * The base 14 family 8{D}: Can be written as 9×14<sup>''n''</sup>−1, it is divisible by 5 if ''n'' is odd and can be factored as (3×14<sup>''n''/2</sup>−1) × (3×14<sup>''n''/2</sup>+1) if ''n'' is even * The base 12 family {B}9B: Can be written as 12<sup>''n''</sup>−25, it is divisible by 13 if ''n'' is odd and can be factored as (12<sup>''n''/2</sup>−5) × (12<sup>''n''/2</sup>+5) if ''n'' is even * The base 17 family 1{9}: Can be written as (25×17<sup>''n''</sup>−9)/16, it is divisible by 2 if ''n'' is odd and can be factored as (5×17<sup>''n''/2</sup>−3) × (5×17<sup>''n''/2</sup>+3) / 16 if ''n'' is even * The base 19 family 1{6}: Can be written as (4×19<sup>''n''</sup>−1)/3, it is divisible by 5 if ''n'' is odd and can be factored as (2×19<sup>''n''/2</sup>−1) × (2×19<sup>''n''/2</sup>+1) / 3 if ''n'' is even By the [[:w:Prime number theorem|prime number theorem]], the [[:w:Probability|chance]] that a [[:w:Random number|random]] ''n''-digit base ''b'' number is prime is [[:w:Asymptotic analysis|approximately]] 1/''n'' (more accurately, the chance is approximately 1/(''n''×''ln''(''b'')), where ''ln'' is the [[:w:Natural logarithm|natural logarithm]]). If one conjectures the numbers ''x''{''y''}''z'' behave similarly (i.e. the numbers ''x''{''y''}''z'' is a [[:w:Pseudorandomness|pseudorandom sequence]]) you would expect [[:w:Harmonic_series (mathematics)|1/1 + 1/2 + 1/3 + 1/4 + ... = ∞]] primes of the form ''x''{''y''}''z'' (of course, this does not always happen, since some ''x''{''y''}''z'' families can be ruled out to contain no prime > ''b'' (by covering congruence, algebraic factorization, or combine of them), but it is at least a reasonable conjecture in the absence of evidence to the contrary. Hence, the [[:w:Heuristic argument|heuristic argument]] suggests there are always infinitely many primes in family ''x''{''y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''y'' is a digit in base ''b'') if it cannot be ruled out to contain no prime or only contain finitely many primes, by covering congruence, algebraic factorization, or combine of them. However, some families ''x''{''y''}''z'' could not be proven to contain no primes > ''b'' (by covering congruence, algebraic factorization, or combine of them) but no primes > ''b'' could be found in the family, even after searching through numbers with over 100000 digits. In such a case, the only way to proceed is to test the primality of larger and larger numbers of such form and hope a prime is eventually discovered. e.g. the smallest (probable) prime in the family A{3}A in base ''b'' = 13 is A3<sub>592197</sub>A, which written in decimal contains 659677 digits (it is only probable prime, i.e. not definitely prime).

problem in decimal (base ''b'' = 10) == '''Bold''' for the minimal elements, ''x'' ◁ ''y'' means ''x'' is a subsequence of ''y''. Assume ''p'' is a prime > 10, and the last digit of ''p'' must lie in {1,3,7,9}. Case 1: ''p'' ends with 1. In this case we can write ''p'' = ''x''1. If ''x'' contains 1, 3, 4, 6, or 7, then (respectively) '''11''' ◁ ''p'', '''31''' ◁ ''p'', '''41''' ◁ ''p'', '''61''' ◁ ''p'', or '''71''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 2, 5, 8, or 9. Case 1.1: ''p'' begins with 2. In this case we can write ''p'' = 2''y''1. If 5 ◁ ''y'', then '''251''' ◁ ''p''. If 8 ◁ ''y'', then '''281''' ◁ ''p''. If 9 ◁ ''y'', then 29 ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 2. If 22 ◁ ''y'', then '''2221''' ◁ ''p''. Hence we may assume ''y'' contains zero or one 2's. If ''y'' contains no 2's, then ''p'' ∈ 2{0}1. But then, since the sum of the digits of ''p'' is 3, ''p'' is divisible by 3, so ''p'' cannot be prime. If ''y'' contains exactly one 2, then we can write ''p'' = 2''z''2''w''1, where ''z'',''w'' ∈ {0}. If 0 ◁ ''z'' and 0 ◁ ''w'', then '''20201''' ◁ ''p''. Hence we may assume either ''z'' or ''w'' is empty. If ''z'' is empty, then ''p'' ∈ 22{0}1, and the smallest prime ''p'' ∈ 22{0}1 is '''22000001'''. If ''w'' is empty, then ''p'' ∈ 2{0}21, and the smallest prime ''p'' ∈ 2{0}21 is '''20021'''. Case 1.2: ''p'' begins with 5. In this case we can write ''p'' = 5''y''1. If 2 ◁ ''y'', then '''521''' ◁ ''p''. If 9 ◁ ''y'', then 59 ◁ ''p''. Hence we may assume all digits of ''y'' are 0, 5, or 8. If 05 ◁ ''y'', then '''5051''' ◁ ''p''. If 08 ◁ ''y'', then '''5081''' ◁ ''p''. If 50 ◁ ''y'', then '''5501''' ◁ ''p''. If 58 ◁ ''y'', then '''5581''' ◁ ''p''. If 80 ◁ ''y'', then '''5801''' ◁ ''p''. If 85 ◁ ''y'', then '''5851''' ◁ ''p''. Hence we may assume ''y'' ∈ {0} ∪ {5} ∪ {8}. If ''y'' ∈ {0}, then ''p'' ∈ 5{0}1. But then, since the sum of the digits of ''p'' is 6, ''p'' is divisible by 3, so ''p'' cannot be prime. If ''y'' ∈ {5}, then ''p'' ∈ 5{5}1, and the smallest prime ''p'' ∈ 5{5}1 is '''555555555551'''. If ''y'' ∈ {8}, since if 88 ◁ ''y'', then 881 ◁ ''p'', hence we may assume ''y'' ∈ {''𝜆'',8}, and thus ''p'' ∈ {51,581}, but 51 and 581 are both composite. Case 1.3: ''p'' begins with 8. In this case we can write p = 8''y''1. If 2 ◁ ''y'', then '''821''' ◁ ''p''. If 8 ◁ ''y'', then '''881''' ◁ ''p''. If 9 ◁ ''y'', then 89 ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 5. If 50 ◁ ''y'', then '''8501''' ◁ ''p''. Hence we may assume y ∈ {0}{5}. If 005 ◁ ''y'', then '''80051''' ◁ p. Hence we may assume y ∈ {0} ∪ {5} ∪ 0{5}. If y ∈ {0}, then ''p'' ∈ 8{0}1. But then, since the sum of the digits of ''p'' is 9, ''p'' is divisible by 3, so ''p'' cannot be prime. If y ∈ {5}, since if 55555555555 ◁ ''y'', then 555555555551 ◁ ''p'', hence we may assume ''y'' ∈ {''𝜆'', 5, 55, 555, 5555, 55555, 555555, 5555555, 55555555, 555555555, 5555555555}, and thus ''p'' ∈ {81, 851, 8551, 85551, 855551, 8555551, 85555551, 855555551, 8555555551, 85555555551, 855555555551}, but all of these numbers are composite. If y ∈ 0{5}, since if 55555555555 ◁ ''y'', then 555555555551 ◁ ''p'', hence we may assume ''y'' ∈ {0, 05, 055, 0555, 05555, 055555, 0555555, 05555555, 055555555, 0555555555, 05555555555}, and thus ''p'' ∈ {801, 8051, 80551, 805551, 8055551, 80555551, 805555551, 8055555551, 80555555551, 805555555551, 8055555555551}, and of these numbers only 80555551 and 8055555551 are primes, but 80555551 ◁ 8055555551, thus only '''80555551''' is a minimal element. Case 1.4: ''p'' begins with 9. In this case we can write p = 9''y''1. If 9 ◁ ''y'', then '''991''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0, 2, 5, or 8. If 00 ◁ ''y'', then '''9001''' ◁ ''p''. If 22 ◁ ''y'', then '''9221''' ◁ ''p''. If 55 ◁ ''y'', then '''9551''' ◁ ''p''. If 88 ◁ ''y'', then 881 ◁ ''p''. Hence we may assume ''y'' contains at most one 0, at most one 2, at most one 5, and at most one 8. If ''y'' only contains at most one 0 and does not contain any of {2,5,8}, then ''y'' ∈ {''𝜆'',0}, and thus ''p'' ∈ {91,901}, but 91 and 901 are both composite. If ''y'' only contains at most one 0 and only one of {2,5,8}, then the sum of the digits of ''p'' is divisible by 3, ''p'' is divisible by 3, so ''p'' cannot be prime. Hence we may assume ''y'' contains at least two of {2,5,8}. If 25 ◁ ''y'', then 251 ◁ ''p''. If 28 ◁ ''y'', then 281 ◁ ''p''. If 52 ◁ ''y'', then 521 ◁ ''p''. If 82 ◁ ''y'', then 821 ◁ ''p''. Hence we may assume ''y'' contains no 2's (since if ''y'' contains 2, then ''y'' cannot contain either 5's or 8's, which is a contradiction). If 85 ◁ ''y'', then '''9851''' ◁ ''p''. Hence we may assume ''y'' ∈ {58,580,508,058}, and thus ''p'' ∈ {9581,95801,95081,90581}, and of these numbers only 95801 is prime, but 95801 is not a minimal element since 5801 ◁ 95801. Case 2: ''p'' ends with 3. In this case we can write p = ''x''3. If ''x'' contains 1, 2, 4, 5, 7, or 8, then (respectively) '''13''' ◁ ''p'', '''23''' ◁ ''p'', '''43''' ◁ ''p'', '''53''' ◁ ''p'', '''73''' ◁ ''p'', or '''83''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 3, 6, or 9, and thus all digits of ''p'' are 0, 3, 6, or 9. But then, since the digits of ''p'' all have a common factor 3, ''p'' is divisible by 3, so ''p'' cannot be prime. Case 3: ''p'' ends with 7. In this case we can write ''p'' = ''x''7. If ''x'' contains 1, 3, 4, 6, or 9, then (respectively) '''17''' ◁ ''p'', '''37''' ◁ ''p'', '''47''' ◁ ''p'', '''67''' ◁ ''p'', or '''97''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 2, 5, 7, or 8. Case 3.1: ''p'' begins with 2. In this case we can write ''p'' = 2''y''7. If 2 ◁ ''y'', then '''227''' ◁ ''p''. If 5 ◁ ''y'', then '''257''' ◁ ''p''. If 7 ◁ ''y'', then '''277''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 8. If 08 ◁ ''y'', then '''2087''' ◁ ''p''. If 88 ◁ ''y'', then 887 ◁ ''p''. Hence we may assume ''y'' ∈ {0} ∪ 8{0}. If ''y'' ∈ {0}, then ''p'' ∈ 2{0}7. But then, since the sum of the digits of ''p'' is 9, ''p'' is divisible by 3, so ''p'' cannot be prime. If y ∈ 8{0}, then ''p'' ∈ 28{0}7. But then ''p'' is divisible by 7, since for ''n'' ≥ 0 we have 7 × 40<sub>''n''</sub>1 = 280<sub>''n''</sub>7. Case 3.2: ''p'' begins with 5. In this case we can write ''p'' = 5''y''7. If 5 ◁ ''y'', then '''557''' ◁ ''p''. If 7 ◁ ''y'', then '''577''' ◁ ''p''. If 8 ◁ ''y'', then '''587''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 2. If 22 ◁ ''y'', then 227 ◁ ''p''. Hence we may assume ''y'' contains zero or one 2's. If ''y'' contains no 2's, then ''p'' ∈ 5{0}7. But then, since the sum of the digits of ''p'' is 12, ''p'' is divisible by 3, so ''p'' cannot be prime. If ''y'' contains exactly one 2, then we can write ''p'' = 5''z''2''w''7, where ''z'',''w'' ∈ {0}. If 0 ◁ ''z'' and 0 ◁ ''w'', then '''50207''' ◁ ''p''. Hence we may assume either ''z'' or ''w'' is empty. If ''z'' is empty, then ''p'' ∈ 52{0}7, and the smallest prime ''p'' ∈ 52{0}7 is '''5200007'''. If ''w'' is empty, then ''p'' ∈ 5{0}27, and the smallest prime ''p'' ∈ 5{0}27 is '''5000000000000000000000000000027'''. Case 3.3: ''p'' begins with 7. In this case we can write ''p'' = 7''y''7. If 2 ◁ ''y'', then '''727''' ◁ ''p''. If 5 ◁ ''y'', then '''757''' ◁ ''p''. If 8 ◁ ''y'', then '''787''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 7, and thus all digits of ''p'' are 0 or 7. But then, since the digits of ''p'' all have a common factor 7, ''p'' is divisible by 7, so ''p'' cannot be prime. Case 3.4: ''p'' begins with 8. In this case we can write ''p'' = 8''y''7. If 2 ◁ ''y'', then '''827''' ◁ ''p''. If 5 ◁ ''y'', then '''857''' ◁ ''p''. If 7 ◁ ''y'', then '''877''' ◁ ''p''. If 8 ◁ ''y'', then '''887''' ◁ ''p''. Hence we may assume ''y'' ∈ {0}, and thus ''p'' ∈ 8{0}7. But then, since the sum of the digits of ''p'' is 15, ''p'' is divisible by 3, so ''p'' cannot be prime. Case 4: ''p'' ends with 9. In this case we can write ''p'' = ''x''9. If ''x'' contains 1, 2, 5, 7, or 8, then (respectively) '''19''' ◁ ''p'', '''29''' ◁ ''p'', '''59''' ◁ ''p'', '''79''' ◁ ''p'', or '''89''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 3, 4, 6, or 9. If 44 ◁ ''x'', then '''449''' ◁ ''p''. Hence we may assume ''x'' contains zero or one 4's. If x contains no 4's, then all digits of ''x'' are 0, 3, 6, or 9, and thus all digits of ''p'' are 0, 3, 6, or 9. But then, since the digits of ''p'' all have a common factor 3, ''p'' is divisible by 3, so ''p'' cannot be prime. Hence we may assume that ''x'' contains exactly one 4. Case 4.1: ''p'' begins with 3. In this case we can write ''p'' = 3''y''4''z''9, where all digits of ''y'', ''z'' are 0, 3, 6, or 9. We must have '''349''' ◁ ''p''. Case 4.2: ''p'' begins with 4. In this case we can write ''p'' = 4''y''9, where all digits of ''y'' are 0, 3, 6, or 9. If 0 ◁ ''y'', then '''409''' ◁ ''p''. If 3 ◁ ''y'', then 43 ◁ ''p''. If 9 ◁ ''y'', then '''499''' ◁ ''p''. Hence we may assume ''y'' ∈ {6}, and thus ''p'' ∈ 4{6}9. But then ''p'' is divisible by 7, since for ''n'' ≥ 0 we have 7 × 6<sub>''n''</sub>7 = 46<sub>''n''</sub>9. Case 4.3: ''p'' begins with 6. In this case we can write p = 6''y''4''z''9, where all digits of ''y'', ''z'' are 0, 3, 6, or 9. If 0 ◁ ''z'', then 409 ◁ ''p''. If 3 ◁ ''z'', then 43 ◁ ''p''. If 6 ◁ ''z'', then '''6469''' ◁ ''p''. If 9 ◁ ''z'', then 499 ◁ ''p''. Hence we may assume ''z'' is empty. If 3 ◁ ''y'', then 349 ◁ ''p''. If 9 ◁ ''y'', then '''6949''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 6. If 06 ◁ ''y'', then '''60649''' ◁ ''p''. Hence we may assume ''y'' ∈ {6}{0}. If 666 ◁ ''y'', then '''666649''' ◁ ''p''. If 00000 ◁ ''y'', then '''60000049''' ◁ ''p''. Hence we may assume ''y'' ∈ {''𝜆'', 0, 00, 000, 0000, 6, 60, 600, 6000, 60000, 66, 660, 6600, 66000, 660000}, and thus ''p'' ∈ {649, 6049, 60049, 600049, 6000049, 6649, 66049, 660049, 6600049, 66000049, 66649, 666049, 6660049, 66600049, 666000049}, and of these numbers only '''66000049''' and '''66600049''' are primes. Case 4.4: ''p'' begins with 9. In this case we can write p = 9''y''4''z''9, where all digits of ''y'', ''z'' are 0, 3, 6, or 9. If 0 ◁ ''y'', then '''9049''' ◁ ''p''. If 3 ◁ ''y'', then 349 ◁ ''p''. If 6 ◁ ''y'', then '''9649''' ◁ ''p''. If 9 ◁ ''y'', then '''9949''' ◁ ''p''. Hence we may assume ''y'' is empty. If 0 ◁ ''z'', then 409 ◁ ''p''. If 3 ◁ ''z'', then 43 ◁ ''p''. If 9 ◁ ''z'', then 499 ◁ ''p''. Hence we may assume ''z'' ∈ {6}, and thus ''p'' ∈ 94{6}9, and the smallest prime ''p'' ∈ 94{6}9 is 946669.

Athena problem is: Give a [[:w:Natural number|natural number]] ''b'' > 1, find the [[:w:Set (mathematics)|set]] of the [[:w:Minimal element|minimal element]]s of the set of the "[[:w:Prime number|prime number]] [[:w:Greater than|>]] ''b''" [[:w:Numerical digit|digit]] [[:w:String (computer science)|string]]s in the [[:w:Positional numeral system|positional numeral system]] with [[:w:Radix|base]] ''b'' for the [[:w:Subsequence|subsequence]] [[:w:Partially ordered set|ordering]]. (A string ''x'' is a subsequence of another string ''y'', if ''x'' can be obtained from ''y'' by deleting zero or more of the [[:w:Character (computing)|character]]s in ''y''. For example, 514 is a subsequence of 352148, "string" is a subsequence of "meistersinger". In contrast, 758 is not a subsequence of 378259, "abc" is not a subsequence of "cbacacba", since the characters must be in the same order) (Unlike [[:w:Substring|substring]], subsequence is not required to occupy consecutive positions within the original sequences) Using [[:w:Formal language theory|formal language theory]] terminology, Athena problem is finding the [[:w:Set (mathematics)|set]] of the [[:w:Minimal element|minimal element]]s of the [[:w:Formal language|language]] of base-''b'' [[:w:Representation (mathematics)|representation]]s of the [[:w:Prime number|prime number]]s [[:w:Greater than|>]] ''b'' (which is a set of [[:w:String (computer science)|string]]s of [[:w:Symbol|symbol]]s over the [[:w:Alphabet (formal languages)|alphabet]] ''Σ''<sub>''b''</sub> := {0, 1, ..., ''b''−1}), under the subsequence ordering (i.e. the [[:w:Binary relation|binary relation]] "is a subsequence of", which is a [[:w:Partially ordered set|partial ordering]]), for a given natural number ''b'' > 1. (You can draw this ordering as [[:w:Hasse diagram|Hasse diagram]] to find all [[:w:Minimal element|minimal element]]s) By [[:w:Higman's lemma|Higman's lemma]], there are no [[:w:Infinite set|infinite]] [[:w:Antichain|antichain]]s for the subsequence ordering (i.e. the subsequence ordering is always a [[:w:Well-quasi-ordering|well quasi order]]) (i.e. under the subsequence ordering (i.e. the [[:w:Binary relation|binary relation]] "is a subsequence of", which is a [[:w:Partially ordered set|partial ordering]]), every set of pairwise incomparable (i.e. not [[:w:Comparability|comparable]]) strings is finite), thus there must be only finitely many such minimal elements. In other words, the set of such minimal elements must be a [[:w:Finite set|finite set]], e.g. in [[:w:Decimal|decimal]] (base ''b'' = 10), this set has exactly 77 [[:w:Element of a set|element]]s: {11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 227, 251, 257, 277, 281, 349, 409, 449, 499, 521, 557, 577, 587, 727, 757, 787, 821, 827, 857, 877, 881, 887, 991, 2087, 2221, 5051, 5081, 5501, 5581, 5801, 5851, 6469, 6949, 8501, 9001, 9049, 9221, 9551, 9649, 9851, 9949, 20021, 20201, 50207, 60649, 80051, 666649, 946669, 5200007, 22000001, 60000049, 66000049, 66600049, 80555551, 555555555551, 5000000000000000000000000000027}. For bases 2 ≤ ''b'' ≤ 36, Athena problem is fully solved in bases ''b'' = 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 14, 15, 18, 20, 24, and also solved in bases ''b'' = 11, 13, 16, 22, 30 if [[:w:Probable prime|probable prime]]s are allowed. For the unsolved bases ''b'' = 17, 19, 21, 23, 25, 26, 27, 28, 29, 31, 32, 34, 35, 36, Athena problem is solved (if probable primes are allowed) except 771 [[:w:Indexed family|families]] of the form ''x''{''y''}''z'' (where ''x'' and ''z'' are strings (may be [[:w:Empty string|empty]]) of digits in base ''b'', ''y'' is a digit in base ''b''), all of these 771 families contain no primes or probable primes with length ≤ 100000. == Results == These are the results of the Athena problem in bases 2 ≤ ''b'' ≤ 36 (we stop at base 36 since this base is the maximum base for which it is possible to write the numbers with the [[:w:Symbol|symbol]]s 0, 1, 2, ..., 9 and A, B, C, ..., Z (i.e. the 10 [[:w:Arabic numerals|Arabic numerals]] and the 26 [[:w:Latin script|Latin letters]]): (some large primes are only probable primes, i.e. not definitely primes, since they are too large to be [[:w:Elliptic curve primality|ECPP proved]] and [[:w:Pocklington primality test#Extensions and variants|neither ''N''−1 nor ''N''+1 can be ≥ 1/3 factored]], all of them pass the [[:w:Baillie–PSW primality test|Baillie–PSW primality test]] and the [[:w:Strong pseudoprime|strong primality test]] (i.e. the [[:w:Miller–Rabin primality test|Miller–Rabin primality test]]) with all prime bases ''p'' ≤ 61, however, all primes < 10<sup>25000</sup> for bases ''b'' = 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 18, 20, 22, 24, 26, 28, 30, 36 are definitely primes, most of them > 10<sup>299</sup> are proven primes with [[:w:Elliptic curve primality|ECPP proving]], others > 10<sup>299</sup> are proven primes with [[:w:Pocklington primality test#Extensions and variants|''N''−1 or ''N''+1 proving]]) To solve the Athena problem for a given base ''b'', we must [[:w:Computing|compute]] the element up to families of the form ''x''{''y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''y'' is a digit in base ''b'') (we call such families ''linear families''), and find the smallest prime > ''b'' in all such families. Shrinking the family ''x''{''Y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''Y'' is a set of digits in base ''b'') * If ''y'' ∈ ''Y'' and the string ''xyyz'' represents a prime > ''b'' in base ''b'' (in this case, add this prime to the list) or has a subsequence which represents a prime > ''b'' in base ''b'', then ''x''{''Y''}''z'' can be replaced with ''x''{''Y'' \ ''y''}''z'' ∪ ''x''{''Y'' \ ''y''}''y''{''Y'' \ ''y''}''z''. * If ''y''<sub>1</sub> ∈ ''Y'' and ''y''<sub>2</sub> ∈ ''Y'' and ''y''<sub>1</sub> ≠ ''y''<sub>2</sub> and the string ''xy''<sub>1</sub>''y''<sub>2</sub>''z'' represents a prime > ''b'' in base ''b'' (in this case, add this prime to the list) or has a subsequence which represents a prime > ''b'' in base ''b'', then ''x''{''Y''}''z'' can be replaced with ''x''{''Y'' \ ''y''<sub>1</sub>}{''Y'' \ ''y''<sub>2</sub>}''z''. * If ''y''<sub>1</sub> ∈ ''Y'' and ''y''<sub>2</sub> ∈ ''Y'' and ''y''<sub>1</sub> ≠ ''y''<sub>2</sub> and both the strings ''xy''<sub>1</sub>''y''<sub>2</sub>''z'' and ''xy''<sub>2</sub>''y''<sub>1</sub>''z'' represent a prime > ''b'' in base ''b'' (in this case, add this prime to the list) or have a subsequence which represents a prime > ''b'' in base ''b'', then ''x''{''Y''}''z'' can be replaced with ''x''{''Y'' \ ''y''<sub>1</sub>}''z'' ∪ ''x''{''Y'' \ ''y''<sub>2</sub>}''z''. e.g. in decimal (base ''b'' = 10): * 2221 is a prime > 10, thus the family 2{0,2}1 splits into the two families 2{0}1 and 2{0}2{0}1. * 227 is a prime > 10, and it is a subsequence of 5227, thus the family 5{0,2}7 splits into the two families 5{0}7 and 5{0}2{0}7. * 449 is a prime > 10, and it is a subsequence of 6449, thus the family 6{0,3,4,6,9}9 splits into the two families 6{0,3,6,9}9 and 6{0,3,6,9}4{0,3,6,9}9. * Both 5051 and 5501 are primes > 10, thus the family 5{0,5}1 splits into the two families 5{0}1 and 5{5}1 = {5}1. * 8501 is a prime > 10, thus the family 8{0,5}1 splits into the family 8{0}{5}1. * 887 is a prime > 10, and it is a subsequence of 2887, also 2087 is a prime > 10, thus the family 2{0,8}7 splits into the two families 2{0}7 and 28{0}7. * 349 and 449 are primes > 10, and they are subsequences of 9349 and 9449, respectively, also 9049, 9649, 9949 are primes > 10, thus the family 9{0,3,4,6,9}9 splits into the two families 9{0,3,6,9}9 and 94{0,3,6,9}9. * 251, 281, 521, 821, 881 are primes > 10, and they are subsequences of 9251, 9281, 9521, 9821, 9881, respectively, also 9001, 9221, 9551, 9851 are primes > 10, thus the family 9{0,2,5,8}1 splits into the numbers {91, 901, 921, 951, 981, 9021, 9051, 9081, 9201, 9501, 9581, 9801, 90581, 95081, 95801}. If the methods we have discussed cannot be used to rule out or shrink ''x''{''Y''}''z'' where ''Y'' = {''y''<sub>1</sub>, ''y''<sub>2</sub>, ..., ''y''<sub>''n''</sub>}, then we can replace ''x''{''Y''}''z'' by ''xy''<sub>1</sub>{''Y''}''z'' ∪ ''xy''<sub>2</sub>{''Y''}''z'' ∪ ... ∪ ''xy''<sub>''n''</sub>{''Y''}''z'' and re-run the methods on this new [[:w:Formal language|language]]. If all remain families are linear families (i.e. of the form ''x''{''y''}''z'', where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''y'' is a digit in base ''b''), then we search the smallest (probable) primes in these families and add these primes to the list. e.g. in decimal (base ''b'' = 10): * The smallest prime in the family 5{0}27 is 5000000000000000000000000000027. * The smallest prime in the family {5}1 is 555555555551. * The smallest prime in the family 8{5}1 is 8555555555555555555551, but 8555555555555555555551 is not a minimal element since 555555555551 is a subsequence of 8555555555555555555551. There is no guarantee that the techniques discussed will ever terminate, but in practice they often do. They are able to determine the set of the minimal elements in base ''b'' for 2 ≤ ''b'' ≤ 16 and ''b'' = 18, 20, 22, 24, 30. The bases ''b'' = 17, 19, 21, 23, 25 ≤ ''b'' ≤ 29, 31 ≤ ''b'' ≤ 36 are solved with the exception of 771 families of the form ''x''{''y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''y'' is a digit in base ''b''). The following is a "[[:w:Semi-algorithm|semi-algorithm]]" that is guaranteed to solve the Athena problem for a given base ''b'', but it is not so easy to implement: # ''M'' = ''[[:w:Empty string|∅]]'' # while (''L'' ≠ ''∅'') do # choose ''x'', a shortest string in ''L'' # ''M'' := ''M'' ∪ {''x''} # ''L'' := ''L'' − ''sup''({''x''}) In practice, for arbitrary ''L'', we cannot feasibly carry out step 5. Instead, we work with ''L''&#39;, some regular overapproximation to ''L'', until we can show ''L''&#39; = ''∅'' (which implies ''L'' = ''∅''). In practice, ''L''&#39; is usually chosen to be a finite [[:w:Union (set theory)|union]] of sets of the form ''L''<sub>1</sub>{''L''<sub>2</sub>}''L''<sub>3</sub>, where each of ''L''<sub>1</sub>, ''L''<sub>2</sub>, ''L''<sub>3</sub> is finite. In the case we consider in this project, we then have to determine whether such a family contains a prime or not. Thus, Athena problem in bases ''b'' around 500 may be [[:w:NP-complete|NP-complete]] or [[:w:NP-hard|NP-hard]], or an [[:w:Undecidable problem|undecidable problem]], or an example of [[:w:Gödel's incompleteness theorems|Gödel's incompleteness theorems]] (like the [[:w:Continuum hypothesis|continuum hypothesis]] and the [[:w:Halting problem|halting problem]]). To solve the Athena problem, we need to determine whether a given family contains a prime. In practice, if family ''x''{''Y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''Y'' is a set of digits in base ''b'') could not be ruled out as only containing composites and ''Y'' contains two or more digits, then a relatively small prime > ''b'' could always be found in this family. Intuitively, this is because there are a large number of small strings in such a family, and at least one is likely to be prime (e.g. there are 2<sup>''n''−2</sup> strings of length ''n'' in the family 1{3,7}9, and there are over a thousand strings of length 12 in the family 1{3,7}9, thus it is very impossible that these numbers are all composite). In the case ''Y'' contains only one digit, this family is of the form ''x''{''y''}''z'', and there is only a single string of each length > (the length of ''x'' + the length of ''z''), and it is not known if the following [[:w:Decision problem|decision problem]] is recursively solvable (just like [[:w:Sierpiński number|Sierpiński problem]] and [[:w:Riesel number|Riesel problem]], Sierpiński problem and Riesel problem can be generalized to other bases ''b'', in fact, Athena problem in base ''b'' covers the Sierpiński problem in base ''b'' and the Riesel problem in base ''b'' with ''k'' < ''b'', i.e. finding the smallest prime of the form ''k''×''b''<sup>''n''</sup>+1 and ''k''×''b''<sup>''n''</sup>−1 (or prove such prime does not exist) with ''k'' < ''b'', since the smallest prime of the form ''k''×''b''<sup>''n''</sup>+1 and ''k''×''b''<sup>''n''</sup>−1 (if exists) must be a minimal element in base ''b''): Problem: Given strings ''x'', ''z'' (may be empty), a digit ''y'', and a base ''b'' (''x'' does not [[:w:Leading zero|start with the digit 0]], ''z'' ends with a digit which [[:w:Coprime integers|coprime]] to ''b'', ''y'' is not 0 if ''x'' is empty, ''y'' is coprime to ''b'' if ''z'' is empty), does there exist a prime number whose base-''b'' expansion is of the form ''xy''<sub>''n''</sub>''z'' for some ''n'' ≥ 0?

Hence, the [[:w:Heuristic argument|heuristic argument]] suggests there are always infinitely many primes in family ''x''{''y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''y'' is a digit in base ''b'') if it cannot be ruled out to contain no prime or only contain finitely many primes, by covering congruence, algebraic factorization, or combine of them. However, some families ''x''{''y''}''z'' could not be proven to contain no primes > ''b'' (by covering congruence, algebraic factorization, or combine of them) but no primes > ''b'' could be found in the family, even after searching through numbers with over 100000 digits.

problem in decimal (base ''b'' = 10) == '''Bold''' for the minimal elements, ''x'' ◁ ''y'' means ''x'' is a subsequence of ''y''. Assume ''p'' is a prime > 10, and the last digit of ''p'' must lie in {1,3,7,9}. Case 1: ''p'' ends with 1. In this case we can write ''p'' = ''x''1. If ''x'' contains 1, 3, 4, 6, or 7, then (respectively) '''11''' ◁ ''p'', '''31''' ◁ ''p'', '''41''' ◁ ''p'', '''61''' ◁ ''p'', or '''71''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 2, 5, 8, or 9. Case 1.1: ''p'' begins with 2. In this case we can write ''p'' = 2''y''1. If 5 ◁ ''y'', then '''251''' ◁ ''p''. If 8 ◁ ''y'', then '''281''' ◁ ''p''. If 9 ◁ ''y'', then 29 ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 2. If 22 ◁ ''y'', then '''2221''' ◁ ''p''. Hence we may assume ''y'' contains zero or one 2's. If ''y'' contains no 2's, then ''p'' ∈ 2{0}1. But then, since the sum of the digits of ''p'' is 3, ''p'' is divisible by 3, so ''p'' cannot be prime. If ''y'' contains exactly one 2, then we can write ''p'' = 2''z''2''w''1, where ''z'',''w'' ∈ {0}. If 0 ◁ ''z'' and 0 ◁ ''w'', then '''20201''' ◁ ''p''. Hence we may assume either ''z'' or ''w'' is empty. If ''z'' is empty, then ''p'' ∈ 22{0}1, and the smallest prime ''p'' ∈ 22{0}1 is '''22000001'''. If ''w'' is empty, then ''p'' ∈ 2{0}21, and the smallest prime ''p'' ∈ 2{0}21 is '''20021'''. Case 1.2: ''p'' begins with 5. In this case we can write ''p'' = 5''y''1. If 2 ◁ ''y'', then '''521''' ◁ ''p''. If 9 ◁ ''y'', then 59 ◁ ''p''. Hence we may assume all digits of ''y'' are 0, 5, or 8. If 05 ◁ ''y'', then '''5051''' ◁ ''p''. If 08 ◁ ''y'', then '''5081''' ◁ ''p''. If 50 ◁ ''y'', then '''5501''' ◁ ''p''. If 58 ◁ ''y'', then '''5581''' ◁ ''p''. If 80 ◁ ''y'', then '''5801''' ◁ ''p''. If 85 ◁ ''y'', then '''5851''' ◁ ''p''. Hence we may assume ''y'' ∈ {0} ∪ {5} ∪ {8}. If ''y'' ∈ {0}, then ''p'' ∈ 5{0}1. But then, since the sum of the digits of ''p'' is 6, ''p'' is divisible by 3, so ''p'' cannot be prime. If ''y'' ∈ {5}, then ''p'' ∈ 5{5}1, and the smallest prime ''p'' ∈ 5{5}1 is '''555555555551'''. If ''y'' ∈ {8}, since if 88 ◁ ''y'', then 881 ◁ ''p'', hence we may assume ''y'' ∈ {''𝜆'',8}, and thus ''p'' ∈ {51,581}, but 51 and 581 are both composite. Case 1.3: ''p'' begins with 8. In this case we can write p = 8''y''1. If 2 ◁ ''y'', then '''821''' ◁ ''p''. If 8 ◁ ''y'', then '''881''' ◁ ''p''. If 9 ◁ ''y'', then 89 ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 5. If 50 ◁ ''y'', then '''8501''' ◁ ''p''. Hence we may assume y ∈ {0}{5}. If 005 ◁ ''y'', then '''80051''' ◁ p. Hence we may assume y ∈ {0} ∪ {5} ∪ 0{5}. If y ∈ {0}, then ''p'' ∈ 8{0}1. But then, since the sum of the digits of ''p'' is 9, ''p'' is divisible by 3, so ''p'' cannot be prime. If y ∈ {5}, since if 55555555555 ◁ ''y'', then 555555555551 ◁ ''p'', hence we may assume ''y'' ∈ {''𝜆'', 5, 55, 555, 5555, 55555, 555555, 5555555, 55555555, 555555555, 5555555555}, and thus ''p'' ∈ {81, 851, 8551, 85551, 855551, 8555551, 85555551, 855555551, 8555555551, 85555555551, 855555555551}, but all of these numbers are composite. If y ∈ 0{5}, since if 55555555555 ◁ ''y'', then 555555555551 ◁ ''p'', hence we may assume ''y'' ∈ {0, 05, 055, 0555, 05555, 055555, 0555555, 05555555, 055555555, 0555555555, 05555555555}, and thus ''p'' ∈ {801, 8051, 80551, 805551, 8055551, 80555551, 805555551, 8055555551, 80555555551, 805555555551, 8055555555551}, and of these numbers only 80555551 and 8055555551 are primes, but 80555551 ◁ 8055555551, thus only '''80555551''' is a minimal element. Case 1.4: ''p'' begins with 9. In this case we can write p = 9''y''1. If 9 ◁ ''y'', then '''991''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0, 2, 5, or 8. If 00 ◁ ''y'', then '''9001''' ◁ ''p''. If 22 ◁ ''y'', then '''9221''' ◁ ''p''. If 55 ◁ ''y'', then '''9551''' ◁ ''p''. If 88 ◁ ''y'', then 881 ◁ ''p''. Hence we may assume ''y'' contains at most one 0, at most one 2, at most one 5, and at most one 8. If ''y'' only contains at most one 0 and does not contain any of {2,5,8}, then ''y'' ∈ {''𝜆'',0}, and thus ''p'' ∈ {91,901}, but 91 and 901 are both composite. If ''y'' only contains at most one 0 and only one of {2,5,8}, then the sum of the digits of ''p'' is divisible by 3, ''p'' is divisible by 3, so ''p'' cannot be prime. Hence we may assume ''y'' contains at least two of {2,5,8}. If 25 ◁ ''y'', then 251 ◁ ''p''. If 28 ◁ ''y'', then 281 ◁ ''p''. If 52 ◁ ''y'', then 521 ◁ ''p''. If 82 ◁ ''y'', then 821 ◁ ''p''. Hence we may assume ''y'' contains no 2's (since if ''y'' contains 2, then ''y'' cannot contain either 5's or 8's, which is a contradiction). If 85 ◁ ''y'', then '''9851''' ◁ ''p''. Hence we may assume ''y'' ∈ {58,580,508,058}, and thus ''p'' ∈ {9581,95801,95081,90581}, and of these numbers only 95801 is prime, but 95801 is not a minimal element since 5801 ◁ 95801. Case 2: ''p'' ends with 3. In this case we can write p = ''x''3. If ''x'' contains 1, 2, 4, 5, 7, or 8, then (respectively) '''13''' ◁ ''p'', '''23''' ◁ ''p'', '''43''' ◁ ''p'', '''53''' ◁ ''p'', '''73''' ◁ ''p'', or '''83''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 3, 6, or 9, and thus all digits of ''p'' are 0, 3, 6, or 9. But then, since the digits of ''p'' all have a common factor 3, ''p'' is divisible by 3, so ''p'' cannot be prime. Case 3: ''p'' ends with 7. In this case we can write ''p'' = ''x''7. If ''x'' contains 1, 3, 4, 6, or 9, then (respectively) '''17''' ◁ ''p'', '''37''' ◁ ''p'', '''47''' ◁ ''p'', '''67''' ◁ ''p'', or '''97''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 2, 5, 7, or 8. Case 3.1: ''p'' begins with 2. In this case we can write ''p'' = 2''y''7. If 2 ◁ ''y'', then '''227''' ◁ ''p''. If 5 ◁ ''y'', then '''257''' ◁ ''p''. If 7 ◁ ''y'', then '''277''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 8. If 08 ◁ ''y'', then '''2087''' ◁ ''p''. If 88 ◁ ''y'', then 887 ◁ ''p''. Hence we may assume ''y'' ∈ {0} ∪ 8{0}. If ''y'' ∈ {0}, then ''p'' ∈ 2{0}7. But then, since the sum of the digits of ''p'' is 9, ''p'' is divisible by 3, so ''p'' cannot be prime. If y ∈ 8{0}, then ''p'' ∈ 28{0}7. But then ''p'' is divisible by 7, since for ''n'' ≥ 0 we have 7 × 40<sub>''n''</sub>1 = 280<sub>''n''</sub>7. Case 3.2: ''p'' begins with 5. In this case we can write ''p'' = 5''y''7. If 5 ◁ ''y'', then '''557''' ◁ ''p''. If 7 ◁ ''y'', then '''577''' ◁ ''p''. If 8 ◁ ''y'', then '''587''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 2. If 22 ◁ ''y'', then 227 ◁ ''p''. Hence we may assume ''y'' contains zero or one 2's. If ''y'' contains no 2's, then ''p'' ∈ 5{0}7. But then, since the sum of the digits of ''p'' is 12, ''p'' is divisible by 3, so ''p'' cannot be prime. If ''y'' contains exactly one 2, then we can write ''p'' = 5''z''2''w''7, where ''z'',''w'' ∈ {0}. If 0 ◁ ''z'' and 0 ◁ ''w'', then '''50207''' ◁ ''p''. Hence we may assume either ''z'' or ''w'' is empty. If ''z'' is empty, then ''p'' ∈ 52{0}7, and the smallest prime ''p'' ∈ 52{0}7 is '''5200007'''. If ''w'' is empty, then ''p'' ∈ 5{0}27, and the smallest prime ''p'' ∈ 5{0}27 is '''5000000000000000000000000000027'''. Case 3.3: ''p'' begins with 7. In this case we can write ''p'' = 7''y''7. If 2 ◁ ''y'', then '''727''' ◁ ''p''. If 5 ◁ ''y'', then '''757''' ◁ ''p''. If 8 ◁ ''y'', then '''787''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 7, and thus all digits of ''p'' are 0 or 7. But then, since the digits of ''p'' all have a common factor 7, ''p'' is divisible by 7, so ''p'' cannot be prime. Case 3.4: ''p'' begins with 8. In this case we can write ''p'' = 8''y''7. If 2 ◁ ''y'', then '''827''' ◁ ''p''. If 5 ◁ ''y'', then '''857''' ◁ ''p''. If 7 ◁ ''y'', then '''877''' ◁ ''p''. If 8 ◁ ''y'', then '''887''' ◁ ''p''. Hence we may assume ''y'' ∈ {0}, and thus ''p'' ∈ 8{0}7. But then, since the sum of the digits of ''p'' is 15, ''p'' is divisible by 3, so ''p'' cannot be prime. Case 4: ''p'' ends with 9. In this case we can write ''p'' = ''x''9. If ''x'' contains 1, 2, 5, 7, or 8, then (respectively) '''19''' ◁ ''p'', '''29''' ◁ ''p'', '''59''' ◁ ''p'', '''79''' ◁ ''p'', or '''89''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 3, 4, 6, or 9. If 44 ◁ ''x'', then '''449''' ◁ ''p''. Hence we may assume ''x'' contains zero or one 4's. If x contains no 4's, then all digits of ''x'' are 0, 3, 6, or 9, and thus all digits of ''p'' are 0, 3, 6, or 9. But then, since the digits of ''p'' all have a common factor 3, ''p'' is divisible by 3, so ''p'' cannot be prime. Hence we may assume that ''x'' contains exactly one 4. Case 4.1: ''p'' begins with 3. In this case we can write ''p'' = 3''y''4''z''9, where all digits of ''y'', ''z'' are 0, 3, 6, or 9. We must have '''349''' ◁ ''p''. Case 4.2: ''p'' begins with 4. In this case we can write ''p'' = 4''y''9, where all digits of ''y'' are 0, 3, 6, or 9. If 0 ◁ ''y'', then '''409''' ◁ ''p''. If 3 ◁ ''y'', then 43 ◁ ''p''. If 9 ◁ ''y'', then '''499''' ◁ ''p''. Hence we may assume ''y'' ∈ {6}, and thus ''p'' ∈ 4{6}9. But then ''p'' is divisible by 7, since for ''n'' ≥ 0 we have 7 × 6<sub>''n''</sub>7 = 46<sub>''n''</sub>9. Case 4.3: ''p'' begins with 6. In this case we can write p = 6''y''4''z''9, where all digits of ''y'', ''z'' are 0, 3, 6, or 9. If 0 ◁ ''z'', then 409 ◁ ''p''. If 3 ◁ ''z'', then 43 ◁ ''p''. If 6 ◁ ''z'', then '''6469''' ◁ ''p''. If 9 ◁ ''z'', then 499 ◁ ''p''. Hence we may assume ''z'' is empty. If 3 ◁ ''y'', then 349 ◁ ''p''. If 9 ◁ ''y'', then '''6949''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 6. If 06 ◁ ''y'', then '''60649''' ◁ ''p''. Hence we may assume ''y'' ∈ {6}{0}. If 666 ◁ ''y'', then '''666649''' ◁ ''p''. If 00000 ◁ ''y'', then '''60000049''' ◁ ''p''. Hence we may assume ''y'' ∈ {''𝜆'', 0, 00, 000, 0000, 6, 60, 600, 6000, 60000, 66, 660, 6600, 66000, 660000}, and thus ''p'' ∈ {649, 6049, 60049, 600049, 6000049, 6649, 66049, 660049, 6600049, 66000049, 66649, 666049, 6660049, 66600049, 666000049}, and of these numbers only '''66000049''' and '''66600049''' are primes. Case 4.4: ''p'' begins with 9. In this case we can write p = 9''y''4''z''9, where all digits of ''y'', ''z'' are 0, 3, 6, or 9. If 0 ◁ ''y'', then '''9049''' ◁ ''p''. If 3 ◁ ''y'', then 349 ◁ ''p''. If 6 ◁ ''y'', then '''9649''' ◁ ''p''. If 9 ◁ ''y'', then '''9949''' ◁ ''p''. Hence we may assume ''y'' is empty. If 0 ◁ ''z'', then 409 ◁ ''p''. If 3 ◁ ''z'', then 43 ◁ ''p''. If 9 ◁ ''z'', then 499 ◁ ''p''. Hence we may assume ''z'' ∈ {6}, and thus ''p'' ∈ 94{6}9, and the smallest prime ''p'' ∈ 94{6}9 is 946669.

Athena problem is: Give a [[:w:Natural number|natural number]] ''b'' > 1, find the [[:w:Set (mathematics)|set]] of the [[:w:Minimal element|minimal element]]s of the set of the "[[:w:Prime number|prime number]] [[:w:Greater than|>]] ''b''" [[:w:Numerical digit|digit]] [[:w:String (computer science)|string]]s in the [[:w:Positional numeral system|positional numeral system]] with [[:w:Radix|base]] ''b'' for the [[:w:Subsequence|subsequence]] [[:w:Partially ordered set|ordering]]. (A string ''x'' is a subsequence of another string ''y'', if ''x'' can be obtained from ''y'' by deleting zero or more of the [[:w:Character (computing)|character]]s in ''y''. For example, 514 is a subsequence of 352148, "string" is a subsequence of "meistersinger". In contrast, 758 is not a subsequence of 378259, "abc" is not a subsequence of "cbacacba", since the characters must be in the same order) (Unlike [[:w:Substring|substring]], subsequence is not required to occupy consecutive positions within the original sequences, e.g. the [[:w:Longest common subsequence|longest common subsequence problem]] is different from the [[:w:Longest common string|longest common string problem]]) Using [[:w:Formal language theory|formal language theory]] terminology, Athena problem is finding the [[:w:Set (mathematics)|set]] of the [[:w:Minimal element|minimal element]]s of the [[:w:Formal language|language]] of base-''b'' [[:w:Representation (mathematics)|representation]]s of the [[:w:Prime number|prime number]]s [[:w:Greater than|>]] ''b'' (which is a set of [[:w:String (computer science)|string]]s of [[:w:Symbol|symbol]]s over the [[:w:Alphabet (formal languages)|alphabet]] ''Σ''<sub>''b''</sub> := {0, 1, ..., ''b''−1}), under the subsequence ordering (i.e. the [[:w:Binary relation|binary relation]] "is a subsequence of", which is a [[:w:Partially ordered set|partial ordering]]), for a given natural number ''b'' > 1. (You can draw this ordering as [[:w:Hasse diagram|Hasse diagram]] to find all [[:w:Minimal element|minimal element]]s) By [[:w:Higman's lemma|Higman's lemma]], there are no [[:w:Infinite set|infinite]] [[:w:Antichain|antichain]]s for the subsequence ordering (i.e. the subsequence ordering is always a [[:w:Well-quasi-ordering|well quasi order]]) (i.e. under the subsequence ordering (i.e. the [[:w:Binary relation|binary relation]] "is a subsequence of", which is a [[:w:Partially ordered set|partial ordering]]), every set of pairwise incomparable (i.e. not [[:w:Comparability|comparable]]) strings is finite), thus there must be only finitely many such minimal elements. In other words, the set of such minimal elements must be a [[:w:Finite set|finite set]], e.g. in [[:w:Decimal|decimal]] (base ''b'' = 10), this set has exactly 77 [[:w:Element of a set|element]]s: {11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 227, 251, 257, 277, 281, 349, 409, 449, 499, 521, 557, 577, 587, 727, 757, 787, 821, 827, 857, 877, 881, 887, 991, 2087, 2221, 5051, 5081, 5501, 5581, 5801, 5851, 6469, 6949, 8501, 9001, 9049, 9221, 9551, 9649, 9851, 9949, 20021, 20201, 50207, 60649, 80051, 666649, 946669, 5200007, 22000001, 60000049, 66000049, 66600049, 80555551, 555555555551, 5000000000000000000000000000027}. For bases 2 ≤ ''b'' ≤ 36, Athena problem is fully solved in bases ''b'' = 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 14, 15, 18, 20, 24, and also solved in bases ''b'' = 11, 13, 16, 22, 30 if [[:w:Probable prime|probable prime]]s are allowed. For the unsolved bases ''b'' = 17, 19, 21, 23, 25, 26, 27, 28, 29, 31, 32, 34, 35, 36, Athena problem is solved (if probable primes are allowed) except 771 [[:w:Indexed family|families]] of the form ''x''{''y''}''z'' (where ''x'' and ''z'' are strings (may be [[:w:Empty string|empty]]) of digits in base ''b'', ''y'' is a digit in base ''b''), all of these 771 families contain no primes or probable primes with length ≤ 100000. == Results == These are the results of the Athena problem in bases 2 ≤ ''b'' ≤ 36 (we stop at base 36 since this base is the maximum base for which it is possible to write the numbers with the [[:w:Symbol|symbol]]s 0, 1, 2, ..., 9 and A, B, C, ..., Z (i.e. the 10 [[:w:Arabic numerals|Arabic numerals]] and the 26 [[:w:Latin script|Latin letters]]): (some large primes are only probable primes, i.e. not definitely primes, since they are too large to be [[:w:Elliptic curve primality|ECPP proved]] and [[:w:Pocklington primality test#Extensions and variants|neither ''N''−1 nor ''N''+1 can be ≥ 1/3 factored]], all of them pass the [[:w:Baillie–PSW primality test|Baillie–PSW primality test]] and the [[:w:Strong pseudoprime|strong primality test]] (i.e. the [[:w:Miller–Rabin primality test|Miller–Rabin primality test]]) with all prime bases ''p'' ≤ 61, however, all primes < 10<sup>25000</sup> for bases ''b'' = 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 18, 20, 22, 24, 26, 28, 30, 36 are definitely primes, most of them > 10<sup>299</sup> are proven primes with [[:w:Elliptic curve primality|ECPP proving]], others > 10<sup>299</sup> are proven primes with [[:w:Pocklington primality test#Extensions and variants|''N''−1 or ''N''+1 proving]]) To solve the Athena problem for a given base ''b'', we must [[:w:Computing|compute]] the element up to families of the form ''x''{''y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''y'' is a digit in base ''b'') (we call such families ''linear families''), and find the smallest prime > ''b'' in all such families.

If the methods we have discussed cannot be used to rule out or shrink ''x''{''Y''}''z'' where ''Y'' = {''y''<sub>1</sub>, ''y''<sub>2</sub>, ..., ''y''<sub>''n''</sub>}, then we can replace ''x''{''Y''}''z'' by ''xy''<sub>1</sub>{''Y''}''z'' ∪ ''xy''<sub>2</sub>{''Y''}''z'' ∪ ... ∪ ''xy''<sub>''n''</sub>{''Y''}''z'' and re-run the methods on this new [[:w:Formal language|language]]. If all remain families are linear families (i.e. of the form ''x''{''y''}''z'', where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''y'' is a digit in base ''b''), then we search the smallest (probable) primes in these families and add these primes to the list. e.g. in decimal (base ''b'' = 10): * The smallest prime in the family 5{0}27 is 5000000000000000000000000000027. * The smallest prime in the family {5}1 is 555555555551. * The smallest prime in the family 8{5}1 is 8555555555555555555551, but 8555555555555555555551 is not a minimal element since 555555555551 is a subsequence of 8555555555555555555551. There is no guarantee that the techniques discussed will ever terminate, but in practice they often do. They are able to determine the set of the minimal elements in base ''b'' for 2 ≤ ''b'' ≤ 16 and ''b'' = 18, 20, 22, 24, 30. The bases ''b'' = 17, 19, 21, 23, 25 ≤ ''b'' ≤ 29, 31 ≤ ''b'' ≤ 36 are solved with the exception of 771 families of the form ''x''{''y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''y'' is a digit in base ''b''). The following is a "[[:w:Semi-algorithm|semi-algorithm]]" that is guaranteed to solve the Athena problem for a given base ''b'', but it is not so easy to implement: # ''M'' = ''[[:w:Empty string|∅]]'' # while (''L'' ≠ ''∅'') do # choose ''x'', a shortest string in ''L'' # ''M'' := ''M'' ∪ {''x''} # ''L'' := ''L'' − ''sup''({''x''}) In practice, for arbitrary ''L'', we cannot feasibly carry out step 5. Instead, we work with ''L''&#39;, some regular overapproximation to ''L'', until we can show ''L''&#39; = ''∅'' (which implies ''L'' = ''∅''). In practice, ''L''&#39; is usually chosen to be a finite [[:w:Union (set theory)|union]] of sets of the form ''L''<sub>1</sub>{''L''<sub>2</sub>}''L''<sub>3</sub>, where each of ''L''<sub>1</sub>, ''L''<sub>2</sub>, ''L''<sub>3</sub> is finite. In the case we consider in this project, we then have to determine whether such a family contains a prime or not. Thus, Athena problem in bases ''b'' around 500 may be [[:w:NP-complete|NP-complete]] or [[:w:NP-hard|NP-hard]], or an [[:w:Undecidable problem|undecidable problem]], or an example of [[:w:Gödel's incompleteness theorems|Gödel's incompleteness theorems]] (like the [[:w:Continuum hypothesis|continuum hypothesis]] and the [[:w:Halting problem|halting problem]]). To solve the Athena problem, we need to determine whether a given family contains a prime. In practice, if family ''x''{''Y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''Y'' is a set of digits in base ''b'') could not be ruled out as only containing composites and ''Y'' contains two or more digits, then a relatively small prime > ''b'' could always be found in this family. Intuitively, this is because there are a large number of small strings in such a family, and at least one is likely to be prime (e.g. there are 2<sup>''n''−2</sup> strings of length ''n'' in the family 1{3,7}9, and there are over a thousand strings of length 12 in the family 1{3,7}9, thus it is very impossible that these numbers are all composite). In the case ''Y'' contains only one digit, this family is of the form ''x''{''y''}''z'', and there is only a single string of each length > (the length of ''x'' + the length of ''z''), and it is not known if the following [[:w:Decision problem|decision problem]] is recursively solvable (just like [[:w:Sierpiński number|Sierpiński problem]] and [[:w:Riesel number|Riesel problem]], Sierpiński problem and Riesel problem can be generalized to other bases ''b'', in fact, Athena problem in base ''b'' covers the Sierpiński problem in base ''b'' and the Riesel problem in base ''b'' with ''k'' < ''b'', i.e. finding the smallest prime of the form ''k''×''b''<sup>''n''</sup>+1 and ''k''×''b''<sup>''n''</sup>−1 (or prove such prime does not exist) with ''k'' < ''b'', since the smallest prime of the form ''k''×''b''<sup>''n''</sup>+1 and ''k''×''b''<sup>''n''</sup>−1 (if exists) must be a minimal element in base ''b''): Problem: Given strings ''x'', ''z'' (may be empty), a digit ''y'', and a base ''b'' (''x'' does not [[:w:Leading zero|start with the digit 0]], ''z'' ends with a digit which [[:w:Coprime integers|coprime]] to ''b'', ''y'' is not 0 if ''x'' is empty, ''y'' is coprime to ''b'' if ''z'' is empty), does there exist a prime number whose base-''b'' expansion is of the form ''xy''<sub>''n''</sub>''z'' for some ''n'' ≥ 0? Some families can be ruled out to contain no prime > ''b'' by [[:w:Covering set|covering congruence]], [[:w:Factorization of polynomials|algebraic factorization]] (e.g. [[:w:Difference of two squares|difference of two squares]], [[:w:Sum of two cubes|sum of two cubes]], [[:w:Sophie Germain's identity|Sophie Germain's identity of ''x''<sup>4</sup>+4×''y''<sup>4</sup>]]), or combine of them, e.g. * The base 9 family 2{7}: Always divisible by 2 or 5 * The base 16 family {8}F: Always divisible by 3, 7, or 13 * The base 21 family {7}D: Always divisible by 2, 13, or 17 * The base 23 family {D}GA: Always divisible by 2, 5, 7, 37, or 79 * The base 9 family 3{8}: Can be written as 4×9<sup>''n''</sup>−1 and can be factored as (2×3<sup>''n''</sup>−1) × (2×3<sup>''n''</sup>+1) * The base 8 family 1{0}1: Can be written as 8<sup>''n''</sup>+1 and can be factored as (2<sup>''n''</sup>+1) × (4<sup>''n''</sup>−2<sup>''n''</sup>+1) * The base 16 family {4}1: Can be written as (4×16<sup>''n''</sup>−49)/15 and can be factored as (2×3<sup>''n''</sup>−7) × (2×3<sup>''n''</sup>+7) / 15 * The base 16 family {C}D: Can be written as (4×16<sup>''n''</sup>+1)/5 and can be factored as (2×4<sup>''n''</sup>−2×2<sup>''n''</sup>+1) × (2×4<sup>''n''</sup>+2×2<sup>''n''</sup>+1) / 5 * The base 14 family 8{D}: Can be written as 9×14<sup>''n''</sup>−1, it is divisible by 5 if ''n'' is odd and can be factored as (3×14<sup>''n''/2</sup>−1) × (3×14<sup>''n''/2</sup>+1) if ''n'' is even * The base 12 family {B}9B: Can be written as 12<sup>''n''</sup>−25, it is divisible by 13 if ''n'' is odd and can be factored as (12<sup>''n''/2</sup>−5) × (12<sup>''n''/2</sup>+5) if ''n'' is even * The base 17 family 1{9}: Can be written as (25×17<sup>''n''</sup>−9)/16, it is divisible by 2 if ''n'' is odd and can be factored as (5×17<sup>''n''/2</sup>−3) × (5×17<sup>''n''/2</sup>+3) / 16 if ''n'' is even * The base 19 family 1{6}: Can be written as (4×19<sup>''n''</sup>−1)/3, it is divisible by 5 if ''n'' is odd and can be factored as (2×19<sup>''n''/2</sup>−1) × (2×19<sup>''n''/2</sup>+1) / 3 if ''n'' is even By the [[:w:Prime number theorem|prime number theorem]], the [[:w:Probability|chance]] that a [[:w:Random number|random]] ''n''-digit base ''b'' number is prime is [[:w:Asymptotic analysis|approximately]] 1/''n'' (more accurately, the chance is approximately 1/(''n''×''ln''(''b'')), where ''ln'' is the [[:w:Natural logarithm|natural logarithm]]). If one conjectures the numbers ''x''{''y''}''z'' behave similarly (i.e. the numbers ''x''{''y''}''z'' is a [[:w:Pseudorandomness|pseudorandom sequence]]) you would expect [[:w:Harmonic_series (mathematics)|1/1 + 1/2 + 1/3 + 1/4 + ... = ∞]] primes of the form ''x''{''y''}''z'' (of course, this does not always happen, since some ''x''{''y''}''z'' families can be ruled out to contain no prime > ''b'' (by covering congruence, algebraic factorization, or combine of them), but it is at least a reasonable conjecture in the absence of evidence to the contrary. Hence, the [[:w:Heuristic argument|heuristic argument]] suggests there are always infinitely many primes in family ''x''{''y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''y'' is a digit in base ''b'') if it cannot be ruled out to contain no prime or only contain finitely many primes, by covering congruence, algebraic factorization, or combine of them. However, some families ''x''{''y''}''z'' could not be proven to contain no primes > ''b'' (by covering congruence, algebraic factorization, or combine of them) but no primes > ''b'' could be found in the family, even after searching through numbers with over 100000 digits. In such a case, the only way to proceed is to [[:w:Primality test|test the primality]] of larger and larger numbers of such form and hope a prime is eventually discovered. e.g. the smallest (probable) prime in the family A{3}A in base ''b'' = 13 is A3<sub>592197</sub>A, which written in decimal contains 659677 digits (it is only probable prime, i.e. not definitely prime).

problem in decimal (base ''b'' = 10) == '''Bold''' for the minimal elements, ''x'' ◁ ''y'' means ''x'' is a subsequence of ''y''. Assume ''p'' is a prime > 10, and the last digit of ''p'' must lie in {1,3,7,9}. Case 1: ''p'' ends with 1. In this case we can write ''p'' = ''x''1. If ''x'' contains 1, 3, 4, 6, or 7, then (respectively) '''11''' ◁ ''p'', '''31''' ◁ ''p'', '''41''' ◁ ''p'', '''61''' ◁ ''p'', or '''71''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 2, 5, 8, or 9. Case 1.1: ''p'' begins with 2. In this case we can write ''p'' = 2''y''1. If 5 ◁ ''y'', then '''251''' ◁ ''p''. If 8 ◁ ''y'', then '''281''' ◁ ''p''. If 9 ◁ ''y'', then 29 ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 2. If 22 ◁ ''y'', then '''2221''' ◁ ''p''. Hence we may assume ''y'' contains zero or one 2's. If ''y'' contains no 2's, then ''p'' ∈ 2{0}1. But then, since the sum of the digits of ''p'' is 3, ''p'' is divisible by 3, so ''p'' cannot be prime. If ''y'' contains exactly one 2, then we can write ''p'' = 2''z''2''w''1, where ''z'',''w'' ∈ {0}. If 0 ◁ ''z'' and 0 ◁ ''w'', then '''20201''' ◁ ''p''. Hence we may assume either ''z'' or ''w'' is empty. If ''z'' is empty, then ''p'' ∈ 22{0}1, and the smallest prime ''p'' ∈ 22{0}1 is '''22000001'''. If ''w'' is empty, then ''p'' ∈ 2{0}21, and the smallest prime ''p'' ∈ 2{0}21 is '''20021'''. Case 1.2: ''p'' begins with 5. In this case we can write ''p'' = 5''y''1. If 2 ◁ ''y'', then '''521''' ◁ ''p''. If 9 ◁ ''y'', then 59 ◁ ''p''. Hence we may assume all digits of ''y'' are 0, 5, or 8. If 05 ◁ ''y'', then '''5051''' ◁ ''p''. If 08 ◁ ''y'', then '''5081''' ◁ ''p''. If 50 ◁ ''y'', then '''5501''' ◁ ''p''. If 58 ◁ ''y'', then '''5581''' ◁ ''p''. If 80 ◁ ''y'', then '''5801''' ◁ ''p''. If 85 ◁ ''y'', then '''5851''' ◁ ''p''. Hence we may assume ''y'' ∈ {0} ∪ {5} ∪ {8}. If ''y'' ∈ {0}, then ''p'' ∈ 5{0}1. But then, since the sum of the digits of ''p'' is 6, ''p'' is divisible by 3, so ''p'' cannot be prime. If ''y'' ∈ {5}, then ''p'' ∈ 5{5}1, and the smallest prime ''p'' ∈ 5{5}1 is '''555555555551'''. If ''y'' ∈ {8}, since if 88 ◁ ''y'', then 881 ◁ ''p'', hence we may assume ''y'' ∈ {''𝜆'',8}, and thus ''p'' ∈ {51,581}, but 51 and 581 are both composite. Case 1.3: ''p'' begins with 8. In this case we can write p = 8''y''1. If 2 ◁ ''y'', then '''821''' ◁ ''p''. If 8 ◁ ''y'', then '''881''' ◁ ''p''. If 9 ◁ ''y'', then 89 ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 5. If 50 ◁ ''y'', then '''8501''' ◁ ''p''. Hence we may assume y ∈ {0}{5}. If 005 ◁ ''y'', then '''80051''' ◁ p. Hence we may assume y ∈ {0} ∪ {5} ∪ 0{5}. If y ∈ {0}, then ''p'' ∈ 8{0}1. But then, since the sum of the digits of ''p'' is 9, ''p'' is divisible by 3, so ''p'' cannot be prime. If y ∈ {5}, since if 55555555555 ◁ ''y'', then 555555555551 ◁ ''p'', hence we may assume ''y'' ∈ {''𝜆'', 5, 55, 555, 5555, 55555, 555555, 5555555, 55555555, 555555555, 5555555555}, and thus ''p'' ∈ {81, 851, 8551, 85551, 855551, 8555551, 85555551, 855555551, 8555555551, 85555555551, 855555555551}, but all of these numbers are composite. If y ∈ 0{5}, since if 55555555555 ◁ ''y'', then 555555555551 ◁ ''p'', hence we may assume ''y'' ∈ {0, 05, 055, 0555, 05555, 055555, 0555555, 05555555, 055555555, 0555555555, 05555555555}, and thus ''p'' ∈ {801, 8051, 80551, 805551, 8055551, 80555551, 805555551, 8055555551, 80555555551, 805555555551, 8055555555551}, and of these numbers only 80555551 and 8055555551 are primes, but 80555551 ◁ 8055555551, thus only '''80555551''' is a minimal element. Case 1.4: ''p'' begins with 9. In this case we can write p = 9''y''1. If 9 ◁ ''y'', then '''991''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0, 2, 5, or 8. If 00 ◁ ''y'', then '''9001''' ◁ ''p''. If 22 ◁ ''y'', then '''9221''' ◁ ''p''. If 55 ◁ ''y'', then '''9551''' ◁ ''p''. If 88 ◁ ''y'', then 881 ◁ ''p''. Hence we may assume ''y'' contains at most one 0, at most one 2, at most one 5, and at most one 8. If ''y'' only contains at most one 0 and does not contain any of {2,5,8}, then ''y'' ∈ {''𝜆'',0}, and thus ''p'' ∈ {91,901}, but 91 and 901 are both composite. If ''y'' only contains at most one 0 and only one of {2,5,8}, then the sum of the digits of ''p'' is divisible by 3, ''p'' is divisible by 3, so ''p'' cannot be prime. Hence we may assume ''y'' contains at least two of {2,5,8}. If 25 ◁ ''y'', then 251 ◁ ''p''. If 28 ◁ ''y'', then 281 ◁ ''p''. If 52 ◁ ''y'', then 521 ◁ ''p''. If 82 ◁ ''y'', then 821 ◁ ''p''. Hence we may assume ''y'' contains no 2's (since if ''y'' contains 2, then ''y'' cannot contain either 5's or 8's, which is a contradiction). If 85 ◁ ''y'', then '''9851''' ◁ ''p''. Hence we may assume ''y'' ∈ {58,580,508,058}, and thus ''p'' ∈ {9581,95801,95081,90581}, and of these numbers only 95801 is prime, but 95801 is not a minimal element since 5801 ◁ 95801. Case 2: ''p'' ends with 3. In this case we can write p = ''x''3. If ''x'' contains 1, 2, 4, 5, 7, or 8, then (respectively) '''13''' ◁ ''p'', '''23''' ◁ ''p'', '''43''' ◁ ''p'', '''53''' ◁ ''p'', '''73''' ◁ ''p'', or '''83''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 3, 6, or 9, and thus all digits of ''p'' are 0, 3, 6, or 9. But then, since the digits of ''p'' all have a common factor 3, ''p'' is divisible by 3, so ''p'' cannot be prime. Case 3: ''p'' ends with 7. In this case we can write ''p'' = ''x''7. If ''x'' contains 1, 3, 4, 6, or 9, then (respectively) '''17''' ◁ ''p'', '''37''' ◁ ''p'', '''47''' ◁ ''p'', '''67''' ◁ ''p'', or '''97''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 2, 5, 7, or 8. Case 3.1: ''p'' begins with 2. In this case we can write ''p'' = 2''y''7. If 2 ◁ ''y'', then '''227''' ◁ ''p''. If 5 ◁ ''y'', then '''257''' ◁ ''p''. If 7 ◁ ''y'', then '''277''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 8. If 08 ◁ ''y'', then '''2087''' ◁ ''p''. If 88 ◁ ''y'', then 887 ◁ ''p''. Hence we may assume ''y'' ∈ {0} ∪ 8{0}. If ''y'' ∈ {0}, then ''p'' ∈ 2{0}7. But then, since the sum of the digits of ''p'' is 9, ''p'' is divisible by 3, so ''p'' cannot be prime. If y ∈ 8{0}, then ''p'' ∈ 28{0}7. But then ''p'' is divisible by 7, since for ''n'' ≥ 0 we have 7 × 40<sub>''n''</sub>1 = 280<sub>''n''</sub>7. Case 3.2: ''p'' begins with 5. In this case we can write ''p'' = 5''y''7. If 5 ◁ ''y'', then '''557''' ◁ ''p''. If 7 ◁ ''y'', then '''577''' ◁ ''p''. If 8 ◁ ''y'', then '''587''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 2. If 22 ◁ ''y'', then 227 ◁ ''p''. Hence we may assume ''y'' contains zero or one 2's. If ''y'' contains no 2's, then ''p'' ∈ 5{0}7. But then, since the sum of the digits of ''p'' is 12, ''p'' is divisible by 3, so ''p'' cannot be prime. If ''y'' contains exactly one 2, then we can write ''p'' = 5''z''2''w''7, where ''z'',''w'' ∈ {0}. If 0 ◁ ''z'' and 0 ◁ ''w'', then '''50207''' ◁ ''p''. Hence we may assume either ''z'' or ''w'' is empty. If ''z'' is empty, then ''p'' ∈ 52{0}7, and the smallest prime ''p'' ∈ 52{0}7 is '''5200007'''. If ''w'' is empty, then ''p'' ∈ 5{0}27, and the smallest prime ''p'' ∈ 5{0}27 is '''5000000000000000000000000000027'''. Case 3.3: ''p'' begins with 7. In this case we can write ''p'' = 7''y''7. If 2 ◁ ''y'', then '''727''' ◁ ''p''. If 5 ◁ ''y'', then '''757''' ◁ ''p''. If 8 ◁ ''y'', then '''787''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 7, and thus all digits of ''p'' are 0 or 7. But then, since the digits of ''p'' all have a common factor 7, ''p'' is divisible by 7, so ''p'' cannot be prime. Case 3.4: ''p'' begins with 8. In this case we can write ''p'' = 8''y''7. If 2 ◁ ''y'', then '''827''' ◁ ''p''. If 5 ◁ ''y'', then '''857''' ◁ ''p''. If 7 ◁ ''y'', then '''877''' ◁ ''p''. If 8 ◁ ''y'', then '''887''' ◁ ''p''. Hence we may assume ''y'' ∈ {0}, and thus ''p'' ∈ 8{0}7. But then, since the sum of the digits of ''p'' is 15, ''p'' is divisible by 3, so ''p'' cannot be prime. Case 4: ''p'' ends with 9. In this case we can write ''p'' = ''x''9. If ''x'' contains 1, 2, 5, 7, or 8, then (respectively) '''19''' ◁ ''p'', '''29''' ◁ ''p'', '''59''' ◁ ''p'', '''79''' ◁ ''p'', or '''89''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 3, 4, 6, or 9. If 44 ◁ ''x'', then '''449''' ◁ ''p''. Hence we may assume ''x'' contains zero or one 4's. If x contains no 4's, then all digits of ''x'' are 0, 3, 6, or 9, and thus all digits of ''p'' are 0, 3, 6, or 9. But then, since the digits of ''p'' all have a common factor 3, ''p'' is divisible by 3, so ''p'' cannot be prime. Hence we may assume that ''x'' contains exactly one 4. Case 4.1: ''p'' begins with 3. In this case we can write ''p'' = 3''y''4''z''9, where all digits of ''y'', ''z'' are 0, 3, 6, or 9. We must have '''349''' ◁ ''p''. Case 4.2: ''p'' begins with 4. In this case we can write ''p'' = 4''y''9, where all digits of ''y'' are 0, 3, 6, or 9. If 0 ◁ ''y'', then '''409''' ◁ ''p''. If 3 ◁ ''y'', then 43 ◁ ''p''. If 9 ◁ ''y'', then '''499''' ◁ ''p''. Hence we may assume ''y'' ∈ {6}, and thus ''p'' ∈ 4{6}9. But then ''p'' is divisible by 7, since for ''n'' ≥ 0 we have 7 × 6<sub>''n''</sub>7 = 46<sub>''n''</sub>9. Case 4.3: ''p'' begins with 6. In this case we can write p = 6''y''4''z''9, where all digits of ''y'', ''z'' are 0, 3, 6, or 9. If 0 ◁ ''z'', then 409 ◁ ''p''. If 3 ◁ ''z'', then 43 ◁ ''p''. If 6 ◁ ''z'', then '''6469''' ◁ ''p''. If 9 ◁ ''z'', then 499 ◁ ''p''. Hence we may assume ''z'' is empty. If 3 ◁ ''y'', then 349 ◁ ''p''. If 9 ◁ ''y'', then '''6949''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 6. If 06 ◁ ''y'', then '''60649''' ◁ ''p''. Hence we may assume ''y'' ∈ {6}{0}. If 666 ◁ ''y'', then '''666649''' ◁ ''p''. If 00000 ◁ ''y'', then '''60000049''' ◁ ''p''. Hence we may assume ''y'' ∈ {''𝜆'', 0, 00, 000, 0000, 6, 60, 600, 6000, 60000, 66, 660, 6600, 66000, 660000}, and thus ''p'' ∈ {649, 6049, 60049, 600049, 6000049, 6649, 66049, 660049, 6600049, 66000049, 66649, 666049, 6660049, 66600049, 666000049}, and of these numbers only '''66000049''' and '''66600049''' are primes. Case 4.4: ''p'' begins with 9. In this case we can write p = 9''y''4''z''9, where all digits of ''y'', ''z'' are 0, 3, 6, or 9. If 0 ◁ ''y'', then '''9049''' ◁ ''p''. If 3 ◁ ''y'', then 349 ◁ ''p''. If 6 ◁ ''y'', then '''9649''' ◁ ''p''. If 9 ◁ ''y'', then '''9949''' ◁ ''p''. Hence we may assume ''y'' is empty. If 0 ◁ ''z'', then 409 ◁ ''p''. If 3 ◁ ''z'', then 43 ◁ ''p''. If 9 ◁ ''z'', then 499 ◁ ''p''. Hence we may assume ''z'' ∈ {6}, and thus ''p'' ∈ 94{6}9, and the smallest prime ''p'' ∈ 94{6}9 is 946669.

Athena problem is: Give a [[:w:Natural number|natural number]] ''b'' > 1, find the [[:w:Set (mathematics)|set]] of the [[:w:Minimal element|minimal element]]s of the set of the "[[:w:Prime number|prime number]] [[:w:Greater than|>]] ''b''" [[:w:Numerical digit|digit]] [[:w:String (computer science)|string]]s in the [[:w:Positional numeral system|positional numeral system]] with [[:w:Radix|base]] ''b'' for the [[:w:Subsequence|subsequence]] [[:w:Partially ordered set|ordering]]. (A string ''x'' is a subsequence of another string ''y'', if ''x'' can be obtained from ''y'' by deleting zero or more of the [[:w:Character (computing)|character]]s in ''y''. For example, 514 is a subsequence of 352148, "string" is a subsequence of "meistersinger". In contrast, 758 is not a subsequence of 378259, "abc" is not a subsequence of "cbacacba", since the characters must be in the same order) (Unlike [[:w:Substring|substring]], subsequence is not required to occupy consecutive positions within the original sequences, e.g. the [[:w:Longest common subsequence|longest common subsequence problem]] is different from the [[:w:Longest common substring|longest common string problem]]) Using [[:w:Formal language theory|formal language theory]] terminology, Athena problem is finding the [[:w:Set (mathematics)|set]] of the [[:w:Minimal element|minimal element]]s of the [[:w:Formal language|language]] of base-''b'' [[:w:Representation (mathematics)|representation]]s of the [[:w:Prime number|prime number]]s [[:w:Greater than|>]] ''b'' (which is a set of [[:w:String (computer science)|string]]s of [[:w:Symbol|symbol]]s over the [[:w:Alphabet (formal languages)|alphabet]] ''Σ''<sub>''b''</sub> := {0, 1, ..., ''b''−1}), under the subsequence ordering (i.e. the [[:w:Binary relation|binary relation]] "is a subsequence of", which is a [[:w:Partially ordered set|partial ordering]]), for a given natural number ''b'' > 1. (You can draw this ordering as [[:w:Hasse diagram|Hasse diagram]] to find all [[:w:Minimal element|minimal element]]s) By [[:w:Higman's lemma|Higman's lemma]], there are no [[:w:Infinite set|infinite]] [[:w:Antichain|antichain]]s for the subsequence ordering (i.e. the subsequence ordering is always a [[:w:Well-quasi-ordering|well quasi order]]) (i.e. under the subsequence ordering (i.e. the [[:w:Binary relation|binary relation]] "is a subsequence of", which is a [[:w:Partially ordered set|partial ordering]]), every set of pairwise incomparable (i.e. not [[:w:Comparability|comparable]]) strings is finite), thus there must be only finitely many such minimal elements. In other words, the set of such minimal elements must be a [[:w:Finite set|finite set]], e.g. in [[:w:Decimal|decimal]] (base ''b'' = 10), this set has exactly 77 [[:w:Element of a set|element]]s: {11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 227, 251, 257, 277, 281, 349, 409, 449, 499, 521, 557, 577, 587, 727, 757, 787, 821, 827, 857, 877, 881, 887, 991, 2087, 2221, 5051, 5081, 5501, 5581, 5801, 5851, 6469, 6949, 8501, 9001, 9049, 9221, 9551, 9649, 9851, 9949, 20021, 20201, 50207, 60649, 80051, 666649, 946669, 5200007, 22000001, 60000049, 66000049, 66600049, 80555551, 555555555551, 5000000000000000000000000000027}.

For the unsolved bases ''b'' = 17, 19, 21, 23, 25, 26, 27, 28, 29, 31, 32, 34, 35, 36, Athena problem is solved (if probable primes are allowed) except 771 [[:w:Indexed family|families]] of the form ''x''{''y''}''z'' (where ''x'' and ''z'' are strings (may be [[:w:Empty string|empty]]) of digits in base ''b'', ''y'' is a digit in base ''b''), all of these 771 families contain no primes or probable primes with length ≤ 100000. == Results == These are the results of the Athena problem in bases 2 ≤ ''b'' ≤ 36 (we stop at base 36 since this base is the maximum base for which it is possible to write the numbers with the [[:w:Symbol|symbol]]s 0, 1, 2, ..., 9 and A, B, C, ..., Z (i.e. the 10 [[:w:Arabic numerals|Arabic numerals]] and the 26 [[:w:Latin script|Latin letters]]): (some large primes are only probable primes, i.e. not definitely primes, since they are too large to be [[:w:Elliptic curve primality|ECPP proved]] and [[:w:Pocklington primality test#Extensions and variants|neither ''N''−1 nor ''N''+1 can be ≥ 1/3 factored]], all of them pass the [[:w:Baillie–PSW primality test|Baillie–PSW primality test]] and the [[:w:Strong pseudoprime|strong primality test]] (i.e. the [[:w:Miller–Rabin primality test|Miller–Rabin primality test]]) with all prime bases ''p'' ≤ 61, however, all primes < 10<sup>25000</sup> for bases ''b'' = 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 18, 20, 22, 24, 26, 28, 30, 36 are definitely primes, most of them > 10<sup>299</sup> are proven primes with [[:w:Elliptic curve primality|ECPP proving]], others > 10<sup>299</sup> are proven primes with [[:w:Pocklington primality test#Extensions and variants|''N''−1 or ''N''+1 proving]]) To solve the Athena problem for a given base ''b'', we must [[:w:Computing|compute]] the element up to families of the form ''x''{''y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''y'' is a digit in base ''b'') (we call such families ''linear families''), and find the smallest prime > ''b'' in all such families.

If the methods we have discussed cannot be used to rule out or shrink ''x''{''Y''}''z'' where ''Y'' = {''y''<sub>1</sub>, ''y''<sub>2</sub>, ..., ''y''<sub>''n''</sub>}, then we can replace ''x''{''Y''}''z'' by ''xy''<sub>1</sub>{''Y''}''z'' ∪ ''xy''<sub>2</sub>{''Y''}''z'' ∪ ... ∪ ''xy''<sub>''n''</sub>{''Y''}''z'' and re-run the methods on this new [[:w:Formal language|language]]. If all remain families are linear families (i.e. of the form ''x''{''y''}''z'', where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''y'' is a digit in base ''b''), then we search the smallest (probable) primes in these families and add these primes to the list. e.g. in decimal (base ''b'' = 10): * The smallest prime in the family 5{0}27 is 5000000000000000000000000000027. * The smallest prime in the family {5}1 is 555555555551. * The smallest prime in the family 8{5}1 is 8555555555555555555551, but 8555555555555555555551 is not a minimal element since 555555555551 is a subsequence of 8555555555555555555551. There is no guarantee that the techniques discussed will ever terminate, but in practice they often do. They are able to determine the set of the minimal elements in base ''b'' for 2 ≤ ''b'' ≤ 16 and ''b'' = 18, 20, 22, 24, 30. The bases ''b'' = 17, 19, 21, 23, 25 ≤ ''b'' ≤ 29, 31 ≤ ''b'' ≤ 36 are solved with the exception of 771 families of the form ''x''{''y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''y'' is a digit in base ''b''). The following is a "[[:w:Semi-algorithm|semi-algorithm]]" that is guaranteed to solve the Athena problem for a given base ''b'', but it is not so easy to implement: # ''M'' = ''[[:w:Empty string|∅]]'' # while (''L'' ≠ ''∅'') do # choose ''x'', a shortest string in ''L'' # ''M'' := ''M'' ∪ {''x''} # ''L'' := ''L'' − ''sup''({''x''}) In practice, for arbitrary ''L'', we cannot feasibly carry out step 5. Instead, we work with ''L''&#39;, some regular overapproximation to ''L'', until we can show ''L''&#39; = ''∅'' (which implies ''L'' = ''∅''). In practice, ''L''&#39; is usually chosen to be a finite [[:w:Union (set theory)|union]] of sets of the form ''L''<sub>1</sub>{''L''<sub>2</sub>}''L''<sub>3</sub>, where each of ''L''<sub>1</sub>, ''L''<sub>2</sub>, ''L''<sub>3</sub> is finite. In the case we consider in this project, we then have to determine whether such a family contains a prime or not. Thus, Athena problem in bases ''b'' around 500 may be [[:w:NP-complete|NP-complete]] or [[:w:NP-hard|NP-hard]], or an [[:w:Undecidable problem|undecidable problem]], or an example of [[:w:Gödel's incompleteness theorems|Gödel's incompleteness theorems]] (like the [[:w:Continuum hypothesis|continuum hypothesis]] and the [[:w:Halting problem|halting problem]]). To solve the Athena problem, we need to determine whether a given family contains a prime. In practice, if family ''x''{''Y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''Y'' is a set of digits in base ''b'') could not be ruled out as only containing composites and ''Y'' contains two or more digits, then a relatively small prime > ''b'' could always be found in this family. Intuitively, this is because there are a large number of small strings in such a family, and at least one is likely to be prime (e.g. there are 2<sup>''n''−2</sup> strings of length ''n'' in the family 1{3,7}9, and there are over a thousand strings of length 12 in the family 1{3,7}9, thus it is very impossible that these numbers are all composite). In the case ''Y'' contains only one digit, this family is of the form ''x''{''y''}''z'', and there is only a single string of each length > (the length of ''x'' + the length of ''z''), and it is not known if the following [[:w:Decision problem|decision problem]] is recursively solvable (just like [[:w:Sierpiński number|Sierpiński problem]] and [[:w:Riesel number|Riesel problem]], Sierpiński problem and Riesel problem can be generalized to other bases ''b'', in fact, Athena problem in base ''b'' covers the Sierpiński problem in base ''b'' and the Riesel problem in base ''b'' with ''k'' < ''b'', i.e. finding the smallest prime of the form ''k''×''b''<sup>''n''</sup>+1 and ''k''×''b''<sup>''n''</sup>−1 (or prove such prime does not exist) with ''k'' < ''b'', since the smallest prime of the form ''k''×''b''<sup>''n''</sup>+1 and ''k''×''b''<sup>''n''</sup>−1 (if exists) must be a minimal element in base ''b''): Problem: Given strings ''x'', ''z'' (may be empty), a digit ''y'', and a base ''b'' (''x'' does not [[:w:Leading zero|start with the digit 0]], ''z'' ends with a digit which [[:w:Coprime integers|coprime]] to ''b'', ''y'' is not 0 if ''x'' is empty, ''y'' is coprime to ''b'' if ''z'' is empty), does there exist a prime number whose base-''b'' expansion is of the form ''xy''<sub>''n''</sub>''z'' for some ''n'' ≥ 0? Some families can be ruled out to contain no prime > ''b'' by [[:w:Covering set|covering congruence]], [[:w:Factorization of polynomials|algebraic factorization]] (e.g. [[:w:Difference of two squares|difference of two squares]], [[:w:Sum of two cubes|sum of two cubes]], [[:w:Sophie Germain's identity|Sophie Germain's identity of ''x''<sup>4</sup>+4×''y''<sup>4</sup>]]), or combine of them, e.g. * The base 9 family 2{7}: Always divisible by 2 or 5 * The base 16 family {8}F: Always divisible by 3, 7, or 13 * The base 21 family {7}D: Always divisible by 2, 13, or 17 * The base 23 family {D}GA: Always divisible by 2, 5, 7, 37, or 79 * The base 9 family 3{8}: Can be written as 4×9<sup>''n''</sup>−1 and can be factored as (2×3<sup>''n''</sup>−1) × (2×3<sup>''n''</sup>+1) * The base 8 family 1{0}1: Can be written as 8<sup>''n''</sup>+1 and can be factored as (2<sup>''n''</sup>+1) × (4<sup>''n''</sup>−2<sup>''n''</sup>+1) * The base 16 family {4}1: Can be written as (4×16<sup>''n''</sup>−49)/15 and can be factored as (2×3<sup>''n''</sup>−7) × (2×3<sup>''n''</sup>+7) / 15 * The base 16 family {C}D: Can be written as (4×16<sup>''n''</sup>+1)/5 and can be factored as (2×4<sup>''n''</sup>−2×2<sup>''n''</sup>+1) × (2×4<sup>''n''</sup>+2×2<sup>''n''</sup>+1) / 5 * The base 14 family 8{D}: Can be written as 9×14<sup>''n''</sup>−1, it is divisible by 5 if ''n'' is odd and can be factored as (3×14<sup>''n''/2</sup>−1) × (3×14<sup>''n''/2</sup>+1) if ''n'' is even * The base 12 family {B}9B: Can be written as 12<sup>''n''</sup>−25, it is divisible by 13 if ''n'' is odd and can be factored as (12<sup>''n''/2</sup>−5) × (12<sup>''n''/2</sup>+5) if ''n'' is even * The base 17 family 1{9}: Can be written as (25×17<sup>''n''</sup>−9)/16, it is divisible by 2 if ''n'' is odd and can be factored as (5×17<sup>''n''/2</sup>−3) × (5×17<sup>''n''/2</sup>+3) / 16 if ''n'' is even * The base 19 family 1{6}: Can be written as (4×19<sup>''n''</sup>−1)/3, it is divisible by 5 if ''n'' is odd and can be factored as (2×19<sup>''n''/2</sup>−1) × (2×19<sup>''n''/2</sup>+1) / 3 if ''n'' is even By the [[:w:Prime number theorem|prime number theorem]], the [[:w:Probability|chance]] that a [[:w:Random number|random]] ''n''-digit base ''b'' number is prime is [[:w:Asymptotic analysis|approximately]] 1/''n'' (more accurately, the chance is approximately 1/(''n''×''ln''(''b'')), where ''ln'' is the [[:w:Natural logarithm|natural logarithm]]). If one conjectures the numbers ''x''{''y''}''z'' behave similarly (i.e. the numbers ''x''{''y''}''z'' is a [[:w:Pseudorandomness|pseudorandom sequence]]) you would expect [[:w:Harmonic_series (mathematics)|1/1 + 1/2 + 1/3 + 1/4 + ... = ∞]] primes of the form ''x''{''y''}''z'' (of course, this does not always happen, since some ''x''{''y''}''z'' families can be ruled out to contain no prime > ''b'' (by covering congruence, algebraic factorization, or combine of them), but it is at least a reasonable conjecture in the absence of evidence to the contrary. Hence, the [[:w:Heuristic argument|heuristic argument]] suggests there are always infinitely many primes in family ''x''{''y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''y'' is a digit in base ''b'') if it cannot be ruled out to contain no prime or only contain finitely many primes, by covering congruence, algebraic factorization, or combine of them. However, some families ''x''{''y''}''z'' could not be proven to contain no primes > ''b'' (by covering congruence, algebraic factorization, or combine of them) but no primes > ''b'' could be found in the family, even after searching through numbers with over 100000 digits. In such a case, the only way to proceed is to [[:w:Primality test|test the primality]] of larger and larger numbers of such form and hope a prime is eventually discovered. e.g. the smallest (probable) prime in the family A{3}A in base ''b'' = 13 is A3<sub>592197</sub>A, which written in decimal contains 659677 digits (it is only probable prime, i.e. not definitely prime).

problem in decimal (base ''b'' = 10) == '''Bold''' for the minimal elements, ''x'' ◁ ''y'' means ''x'' is a subsequence of ''y''. Assume ''p'' is a prime > 10, and the last digit of ''p'' must lie in {1,3,7,9}. Case 1: ''p'' ends with 1. In this case we can write ''p'' = ''x''1. If ''x'' contains 1, 3, 4, 6, or 7, then (respectively) '''11''' ◁ ''p'', '''31''' ◁ ''p'', '''41''' ◁ ''p'', '''61''' ◁ ''p'', or '''71''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 2, 5, 8, or 9. Case 1.1: ''p'' begins with 2. In this case we can write ''p'' = 2''y''1. If 5 ◁ ''y'', then '''251''' ◁ ''p''. If 8 ◁ ''y'', then '''281''' ◁ ''p''. If 9 ◁ ''y'', then 29 ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 2. If 22 ◁ ''y'', then '''2221''' ◁ ''p''. Hence we may assume ''y'' contains zero or one 2's. If ''y'' contains no 2's, then ''p'' ∈ 2{0}1. But then, since the sum of the digits of ''p'' is 3, ''p'' is divisible by 3, so ''p'' cannot be prime. If ''y'' contains exactly one 2, then we can write ''p'' = 2''z''2''w''1, where ''z'',''w'' ∈ {0}. If 0 ◁ ''z'' and 0 ◁ ''w'', then '''20201''' ◁ ''p''. Hence we may assume either ''z'' or ''w'' is empty. If ''z'' is empty, then ''p'' ∈ 22{0}1, and the smallest prime ''p'' ∈ 22{0}1 is '''22000001'''. If ''w'' is empty, then ''p'' ∈ 2{0}21, and the smallest prime ''p'' ∈ 2{0}21 is '''20021'''. Case 1.2: ''p'' begins with 5. In this case we can write ''p'' = 5''y''1. If 2 ◁ ''y'', then '''521''' ◁ ''p''. If 9 ◁ ''y'', then 59 ◁ ''p''. Hence we may assume all digits of ''y'' are 0, 5, or 8. If 05 ◁ ''y'', then '''5051''' ◁ ''p''. If 08 ◁ ''y'', then '''5081''' ◁ ''p''. If 50 ◁ ''y'', then '''5501''' ◁ ''p''. If 58 ◁ ''y'', then '''5581''' ◁ ''p''. If 80 ◁ ''y'', then '''5801''' ◁ ''p''. If 85 ◁ ''y'', then '''5851''' ◁ ''p''. Hence we may assume ''y'' ∈ {0} ∪ {5} ∪ {8}. If ''y'' ∈ {0}, then ''p'' ∈ 5{0}1. But then, since the sum of the digits of ''p'' is 6, ''p'' is divisible by 3, so ''p'' cannot be prime. If ''y'' ∈ {5}, then ''p'' ∈ 5{5}1, and the smallest prime ''p'' ∈ 5{5}1 is '''555555555551'''. If ''y'' ∈ {8}, since if 88 ◁ ''y'', then 881 ◁ ''p'', hence we may assume ''y'' ∈ {''𝜆'',8}, and thus ''p'' ∈ {51,581}, but 51 and 581 are both composite. Case 1.3: ''p'' begins with 8. In this case we can write p = 8''y''1. If 2 ◁ ''y'', then '''821''' ◁ ''p''. If 8 ◁ ''y'', then '''881''' ◁ ''p''. If 9 ◁ ''y'', then 89 ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 5. If 50 ◁ ''y'', then '''8501''' ◁ ''p''. Hence we may assume y ∈ {0}{5}. If 005 ◁ ''y'', then '''80051''' ◁ p. Hence we may assume y ∈ {0} ∪ {5} ∪ 0{5}. If y ∈ {0}, then ''p'' ∈ 8{0}1. But then, since the sum of the digits of ''p'' is 9, ''p'' is divisible by 3, so ''p'' cannot be prime. If y ∈ {5}, since if 55555555555 ◁ ''y'', then 555555555551 ◁ ''p'', hence we may assume ''y'' ∈ {''𝜆'', 5, 55, 555, 5555, 55555, 555555, 5555555, 55555555, 555555555, 5555555555}, and thus ''p'' ∈ {81, 851, 8551, 85551, 855551, 8555551, 85555551, 855555551, 8555555551, 85555555551, 855555555551}, but all of these numbers are composite. If y ∈ 0{5}, since if 55555555555 ◁ ''y'', then 555555555551 ◁ ''p'', hence we may assume ''y'' ∈ {0, 05, 055, 0555, 05555, 055555, 0555555, 05555555, 055555555, 0555555555, 05555555555}, and thus ''p'' ∈ {801, 8051, 80551, 805551, 8055551, 80555551, 805555551, 8055555551, 80555555551, 805555555551, 8055555555551}, and of these numbers only 80555551 and 8055555551 are primes, but 80555551 ◁ 8055555551, thus only '''80555551''' is a minimal element. Case 1.4: ''p'' begins with 9. In this case we can write p = 9''y''1. If 9 ◁ ''y'', then '''991''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0, 2, 5, or 8. If 00 ◁ ''y'', then '''9001''' ◁ ''p''. If 22 ◁ ''y'', then '''9221''' ◁ ''p''. If 55 ◁ ''y'', then '''9551''' ◁ ''p''. If 88 ◁ ''y'', then 881 ◁ ''p''. Hence we may assume ''y'' contains at most one 0, at most one 2, at most one 5, and at most one 8. If ''y'' only contains at most one 0 and does not contain any of {2,5,8}, then ''y'' ∈ {''𝜆'',0}, and thus ''p'' ∈ {91,901}, but 91 and 901 are both composite. If ''y'' only contains at most one 0 and only one of {2,5,8}, then the sum of the digits of ''p'' is divisible by 3, ''p'' is divisible by 3, so ''p'' cannot be prime. Hence we may assume ''y'' contains at least two of {2,5,8}. If 25 ◁ ''y'', then 251 ◁ ''p''. If 28 ◁ ''y'', then 281 ◁ ''p''. If 52 ◁ ''y'', then 521 ◁ ''p''. If 82 ◁ ''y'', then 821 ◁ ''p''. Hence we may assume ''y'' contains no 2's (since if ''y'' contains 2, then ''y'' cannot contain either 5's or 8's, which is a contradiction). If 85 ◁ ''y'', then '''9851''' ◁ ''p''. Hence we may assume ''y'' ∈ {58,580,508,058}, and thus ''p'' ∈ {9581,95801,95081,90581}, and of these numbers only 95801 is prime, but 95801 is not a minimal element since 5801 ◁ 95801. Case 2: ''p'' ends with 3. In this case we can write p = ''x''3. If ''x'' contains 1, 2, 4, 5, 7, or 8, then (respectively) '''13''' ◁ ''p'', '''23''' ◁ ''p'', '''43''' ◁ ''p'', '''53''' ◁ ''p'', '''73''' ◁ ''p'', or '''83''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 3, 6, or 9, and thus all digits of ''p'' are 0, 3, 6, or 9. But then, since the digits of ''p'' all have a common factor 3, ''p'' is divisible by 3, so ''p'' cannot be prime. Case 3: ''p'' ends with 7. In this case we can write ''p'' = ''x''7. If ''x'' contains 1, 3, 4, 6, or 9, then (respectively) '''17''' ◁ ''p'', '''37''' ◁ ''p'', '''47''' ◁ ''p'', '''67''' ◁ ''p'', or '''97''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 2, 5, 7, or 8. Case 3.1: ''p'' begins with 2. In this case we can write ''p'' = 2''y''7. If 2 ◁ ''y'', then '''227''' ◁ ''p''. If 5 ◁ ''y'', then '''257''' ◁ ''p''. If 7 ◁ ''y'', then '''277''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 8. If 08 ◁ ''y'', then '''2087''' ◁ ''p''. If 88 ◁ ''y'', then 887 ◁ ''p''. Hence we may assume ''y'' ∈ {0} ∪ 8{0}. If ''y'' ∈ {0}, then ''p'' ∈ 2{0}7. But then, since the sum of the digits of ''p'' is 9, ''p'' is divisible by 3, so ''p'' cannot be prime. If y ∈ 8{0}, then ''p'' ∈ 28{0}7. But then ''p'' is divisible by 7, since for ''n'' ≥ 0 we have 7 × 40<sub>''n''</sub>1 = 280<sub>''n''</sub>7. Case 3.2: ''p'' begins with 5. In this case we can write ''p'' = 5''y''7. If 5 ◁ ''y'', then '''557''' ◁ ''p''. If 7 ◁ ''y'', then '''577''' ◁ ''p''. If 8 ◁ ''y'', then '''587''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 2. If 22 ◁ ''y'', then 227 ◁ ''p''. Hence we may assume ''y'' contains zero or one 2's. If ''y'' contains no 2's, then ''p'' ∈ 5{0}7. But then, since the sum of the digits of ''p'' is 12, ''p'' is divisible by 3, so ''p'' cannot be prime. If ''y'' contains exactly one 2, then we can write ''p'' = 5''z''2''w''7, where ''z'',''w'' ∈ {0}. If 0 ◁ ''z'' and 0 ◁ ''w'', then '''50207''' ◁ ''p''. Hence we may assume either ''z'' or ''w'' is empty. If ''z'' is empty, then ''p'' ∈ 52{0}7, and the smallest prime ''p'' ∈ 52{0}7 is '''5200007'''. If ''w'' is empty, then ''p'' ∈ 5{0}27, and the smallest prime ''p'' ∈ 5{0}27 is '''5000000000000000000000000000027'''. Case 3.3: ''p'' begins with 7. In this case we can write ''p'' = 7''y''7. If 2 ◁ ''y'', then '''727''' ◁ ''p''. If 5 ◁ ''y'', then '''757''' ◁ ''p''. If 8 ◁ ''y'', then '''787''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 7, and thus all digits of ''p'' are 0 or 7. But then, since the digits of ''p'' all have a common factor 7, ''p'' is divisible by 7, so ''p'' cannot be prime. Case 3.4: ''p'' begins with 8. In this case we can write ''p'' = 8''y''7. If 2 ◁ ''y'', then '''827''' ◁ ''p''. If 5 ◁ ''y'', then '''857''' ◁ ''p''. If 7 ◁ ''y'', then '''877''' ◁ ''p''. If 8 ◁ ''y'', then '''887''' ◁ ''p''. Hence we may assume ''y'' ∈ {0}, and thus ''p'' ∈ 8{0}7. But then, since the sum of the digits of ''p'' is 15, ''p'' is divisible by 3, so ''p'' cannot be prime. Case 4: ''p'' ends with 9. In this case we can write ''p'' = ''x''9. If ''x'' contains 1, 2, 5, 7, or 8, then (respectively) '''19''' ◁ ''p'', '''29''' ◁ ''p'', '''59''' ◁ ''p'', '''79''' ◁ ''p'', or '''89''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 3, 4, 6, or 9. If 44 ◁ ''x'', then '''449''' ◁ ''p''. Hence we may assume ''x'' contains zero or one 4's. If x contains no 4's, then all digits of ''x'' are 0, 3, 6, or 9, and thus all digits of ''p'' are 0, 3, 6, or 9. But then, since the digits of ''p'' all have a common factor 3, ''p'' is divisible by 3, so ''p'' cannot be prime. Hence we may assume that ''x'' contains exactly one 4. Case 4.1: ''p'' begins with 3. In this case we can write ''p'' = 3''y''4''z''9, where all digits of ''y'', ''z'' are 0, 3, 6, or 9. We must have '''349''' ◁ ''p''. Case 4.2: ''p'' begins with 4. In this case we can write ''p'' = 4''y''9, where all digits of ''y'' are 0, 3, 6, or 9. If 0 ◁ ''y'', then '''409''' ◁ ''p''. If 3 ◁ ''y'', then 43 ◁ ''p''. If 9 ◁ ''y'', then '''499''' ◁ ''p''. Hence we may assume ''y'' ∈ {6}, and thus ''p'' ∈ 4{6}9. But then ''p'' is divisible by 7, since for ''n'' ≥ 0 we have 7 × 6<sub>''n''</sub>7 = 46<sub>''n''</sub>9. Case 4.3: ''p'' begins with 6. In this case we can write p = 6''y''4''z''9, where all digits of ''y'', ''z'' are 0, 3, 6, or 9. If 0 ◁ ''z'', then 409 ◁ ''p''. If 3 ◁ ''z'', then 43 ◁ ''p''. If 6 ◁ ''z'', then '''6469''' ◁ ''p''. If 9 ◁ ''z'', then 499 ◁ ''p''. Hence we may assume ''z'' is empty. If 3 ◁ ''y'', then 349 ◁ ''p''. If 9 ◁ ''y'', then '''6949''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 6. If 06 ◁ ''y'', then '''60649''' ◁ ''p''. Hence we may assume ''y'' ∈ {6}{0}. If 666 ◁ ''y'', then '''666649''' ◁ ''p''. If 00000 ◁ ''y'', then '''60000049''' ◁ ''p''. Hence we may assume ''y'' ∈ {''𝜆'', 0, 00, 000, 0000, 6, 60, 600, 6000, 60000, 66, 660, 6600, 66000, 660000}, and thus ''p'' ∈ {649, 6049, 60049, 600049, 6000049, 6649, 66049, 660049, 6600049, 66000049, 66649, 666049, 6660049, 66600049, 666000049}, and of these numbers only '''66000049''' and '''66600049''' are primes. Case 4.4: ''p'' begins with 9. In this case we can write p = 9''y''4''z''9, where all digits of ''y'', ''z'' are 0, 3, 6, or 9. If 0 ◁ ''y'', then '''9049''' ◁ ''p''. If 3 ◁ ''y'', then 349 ◁ ''p''. If 6 ◁ ''y'', then '''9649''' ◁ ''p''. If 9 ◁ ''y'', then '''9949''' ◁ ''p''. Hence we may assume ''y'' is empty. If 0 ◁ ''z'', then 409 ◁ ''p''. If 3 ◁ ''z'', then 43 ◁ ''p''. If 9 ◁ ''z'', then 499 ◁ ''p''. Hence we may assume ''z'' ∈ {6}, and thus ''p'' ∈ 94{6}9, and the smallest prime ''p'' ∈ 94{6}9 is 946669.

Athena problem is: Give a [[:w:Natural number|natural number]] ''b'' > 1, find the [[:w:Set (mathematics)|set]] of the [[:w:Minimal element|minimal element]]s of the set of the "[[:w:Prime number|prime number]] [[:w:Greater than|>]] ''b''" [[:w:Numerical digit|digit]] [[:w:String (computer science)|string]]s in the [[:w:Positional numeral system|positional numeral system]] with [[:w:Radix|base]] ''b'' for the [[:w:Subsequence|subsequence]] [[:w:Partially ordered set|ordering]]. (A string ''x'' is a subsequence of another string ''y'', if ''x'' can be obtained from ''y'' by deleting zero or more of the [[:w:Character (computing)|character]]s in ''y''. For example, 514 is a subsequence of 352148, "string" is a subsequence of "meistersinger". In contrast, 758 is not a subsequence of 378259, "abc" is not a subsequence of "cbacacba", since the characters must be in the same order) (Unlike [[:w:Substring|substring]], subsequence is not required to occupy consecutive positions within the original sequences, e.g. the [[:w:Longest common subsequence|longest common subsequence problem]] is different from the [[:w:Longest common substring|longest common substring problem]]) Using [[:w:Formal language theory|formal language theory]] terminology, Athena problem is finding the [[:w:Set (mathematics)|set]] of the [[:w:Minimal element|minimal element]]s of the [[:w:Formal language|language]] of base-''b'' [[:w:Representation (mathematics)|representation]]s of the [[:w:Prime number|prime number]]s [[:w:Greater than|>]] ''b'' (which is a set of [[:w:String (computer science)|string]]s of [[:w:Symbol|symbol]]s over the [[:w:Alphabet (formal languages)|alphabet]] ''Σ''<sub>''b''</sub> := {0, 1, ..., ''b''−1}), under the subsequence ordering (i.e. the [[:w:Binary relation|binary relation]] "is a subsequence of", which is a [[:w:Partially ordered set|partial ordering]]), for a given natural number ''b'' > 1. (You can draw this ordering as [[:w:Hasse diagram|Hasse diagram]] to find all [[:w:Minimal element|minimal element]]s) By [[:w:Higman's lemma|Higman's lemma]], there are no [[:w:Infinite set|infinite]] [[:w:Antichain|antichain]]s for the subsequence ordering (i.e. the subsequence ordering is always a [[:w:Well-quasi-ordering|well quasi order]]) (i.e. under the subsequence ordering (i.e. the [[:w:Binary relation|binary relation]] "is a subsequence of", which is a [[:w:Partially ordered set|partial ordering]]), every set of pairwise incomparable (i.e. not [[:w:Comparability|comparable]]) strings is finite), thus there must be only finitely many such minimal elements. In other words, the set of such minimal elements must be a [[:w:Finite set|finite set]], e.g. in [[:w:Decimal|decimal]] (base ''b'' = 10), this set has exactly 77 [[:w:Element of a set|element]]s: {11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 227, 251, 257, 277, 281, 349, 409, 449, 499, 521, 557, 577, 587, 727, 757, 787, 821, 827, 857, 877, 881, 887, 991, 2087, 2221, 5051, 5081, 5501, 5581, 5801, 5851, 6469, 6949, 8501, 9001, 9049, 9221, 9551, 9649, 9851, 9949, 20021, 20201, 50207, 60649, 80051, 666649, 946669, 5200007, 22000001, 60000049, 66000049, 66600049, 80555551, 555555555551, 5000000000000000000000000000027}.

If the methods we have discussed cannot be used to rule out or shrink ''x''{''Y''}''z'' where ''Y'' = {''y''<sub>1</sub>, ''y''<sub>2</sub>, ..., ''y''<sub>''n''</sub>}, then we can replace ''x''{''Y''}''z'' by ''xy''<sub>1</sub>{''Y''}''z'' ∪ ''xy''<sub>2</sub>{''Y''}''z'' ∪ ... ∪ ''xy''<sub>''n''</sub>{''Y''}''z'' and re-run the methods on this new [[:w:Formal language|language]]. If all remain families are linear families (i.e. of the form ''x''{''y''}''z'', where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''y'' is a digit in base ''b''), then we search the smallest (probable) primes in these families and add these primes to the list. e.g. in decimal (base ''b'' = 10): * The smallest prime in the family 5{0}27 is 5000000000000000000000000000027. * The smallest prime in the family {5}1 is 555555555551. * The smallest prime in the family 8{5}1 is 8555555555555555555551, but 8555555555555555555551 is not a minimal element since 555555555551 is a subsequence of 8555555555555555555551. There is no guarantee that the techniques discussed will ever terminate, but in practice they often do. They are able to determine the set of the minimal elements in base ''b'' for 2 ≤ ''b'' ≤ 16 and ''b'' = 18, 20, 22, 24, 30. The bases ''b'' = 17, 19, 21, 23, 25 ≤ ''b'' ≤ 29, 31 ≤ ''b'' ≤ 36 are solved with the exception of 771 families of the form ''x''{''y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''y'' is a digit in base ''b''). The following is a "[[:w:Semi-algorithm|semi-algorithm]]" that is guaranteed to solve the Athena problem for a given base ''b'', but it is not so easy to implement: # ''M'' = ''[[:w:Empty string|∅]]'' # while (''L'' ≠ ''∅'') do # choose ''x'', a shortest string in ''L'' # ''M'' := ''M'' ∪ {''x''} # ''L'' := ''L'' − ''sup''({''x''}) In practice, for arbitrary ''L'', we cannot feasibly carry out step 5. Instead, we work with ''L''&#39;, some regular overapproximation to ''L'', until we can show ''L''&#39; = ''∅'' (which implies ''L'' = ''∅''). In practice, ''L''&#39; is usually chosen to be a finite [[:w:Union (set theory)|union]] of sets of the form ''L''<sub>1</sub>{''L''<sub>2</sub>}''L''<sub>3</sub>, where each of ''L''<sub>1</sub>, ''L''<sub>2</sub>, ''L''<sub>3</sub> is finite. In the case we consider in this project, we then have to determine whether such a family contains a prime or not. Thus, Athena problem in bases ''b'' around 500 may be [[:w:NP-complete|NP-complete]] or [[:w:NP-hard|NP-hard]], or an [[:w:Undecidable problem|undecidable problem]], or an example of [[:w:Gödel's incompleteness theorems|Gödel's incompleteness theorems]] (like the [[:w:Continuum hypothesis|continuum hypothesis]] and the [[:w:Halting problem|halting problem]]). To solve the Athena problem, we need to determine whether a given family contains a prime. In practice, if family ''x''{''Y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''Y'' is a set of digits in base ''b'') could not be ruled out as only containing composites and ''Y'' contains two or more digits, then a relatively small prime > ''b'' could always be found in this family. Intuitively, this is because there are a large number of small strings in such a family, and at least one is likely to be prime (e.g. there are 2<sup>''n''−2</sup> strings of length ''n'' in the family 1{3,7}9, and there are over a thousand strings of length 12 in the family 1{3,7}9, thus it is very impossible that these numbers are all composite). In the case ''Y'' contains only one digit, this family is of the form ''x''{''y''}''z'', and there is only a single string of each length > (the length of ''x'' + the length of ''z''), and it is not known if the following [[:w:Decision problem|decision problem]] is recursively solvable (just like [[:w:Sierpiński number|Sierpiński problem]] and [[:w:Riesel number|Riesel problem]], Sierpiński problem and Riesel problem can be generalized to other bases ''b'', in fact, Athena problem in base ''b'' covers the Sierpiński problem in base ''b'' and the Riesel problem in base ''b'' with ''k'' < ''b'', i.e. finding the smallest prime of the form ''k''×''b''<sup>''n''</sup>+1 and ''k''×''b''<sup>''n''</sup>−1 (or prove such prime does not exist) with ''k'' < ''b'', since the smallest prime of the form ''k''×''b''<sup>''n''</sup>+1 and ''k''×''b''<sup>''n''</sup>−1 (if exists) must be a minimal element in base ''b''): Problem: Given strings ''x'', ''z'' (may be empty), a digit ''y'', and a base ''b'' (''x'' does not [[:w:Leading zero|start with the digit 0]], ''z'' ends with a digit which [[:w:Coprime integers|coprime]] to ''b'', ''y'' is not 0 if ''x'' is empty, ''y'' is coprime to ''b'' if ''z'' is empty), does there exist a prime number whose base-''b'' expansion is of the form ''xy''<sub>''n''</sub>''z'' for some ''n'' ≥ 0? Some families can be ruled out to contain no prime > ''b'' by [[:w:Covering set|covering congruence]], [[:w:Factorization of polynomials|algebraic factorization]] (e.g. [[:w:Difference of two squares|difference of two squares]], [[:w:Sum of two cubes|sum of two cubes]], [[:w:Sophie Germain's identity|Sophie Germain's identity of ''x''<sup>4</sup>+4×''y''<sup>4</sup>]]), or combine of them, e.g. * The base 9 family 2{7}: Always divisible by 2 or 5 * The base 16 family {8}F: Always divisible by 3, 7, or 13 * The base 21 family {7}D: Always divisible by 2, 13, or 17 * The base 23 family {D}GA: Always divisible by 2, 5, 7, 37, or 79 * The base 9 family 3{8}: Can be written as 4×9<sup>''n''</sup>−1 and can be factored as (2×3<sup>''n''</sup>−1) × (2×3<sup>''n''</sup>+1) * The base 8 family 1{0}1: Can be written as 8<sup>''n''</sup>+1 and can be factored as (2<sup>''n''</sup>+1) × (4<sup>''n''</sup>−2<sup>''n''</sup>+1) * The base 16 family {4}1: Can be written as (4×16<sup>''n''</sup>−49)/15 and can be factored as (2×3<sup>''n''</sup>−7) × (2×3<sup>''n''</sup>+7) / 15 * The base 16 family {C}D: Can be written as (4×16<sup>''n''</sup>+1)/5 and can be factored as (2×4<sup>''n''</sup>−2×2<sup>''n''</sup>+1) × (2×4<sup>''n''</sup>+2×2<sup>''n''</sup>+1) / 5 * The base 14 family 8{D}: Can be written as 9×14<sup>''n''</sup>−1, it is divisible by 5 if ''n'' is odd and can be factored as (3×14<sup>''n''/2</sup>−1) × (3×14<sup>''n''/2</sup>+1) if ''n'' is even * The base 12 family {B}9B: Can be written as 12<sup>''n''</sup>−25, it is divisible by 13 if ''n'' is odd and can be factored as (12<sup>''n''/2</sup>−5) × (12<sup>''n''/2</sup>+5) if ''n'' is even * The base 17 family 1{9}: Can be written as (25×17<sup>''n''</sup>−9)/16, it is divisible by 2 if ''n'' is odd and can be factored as (5×17<sup>''n''/2</sup>−3) × (5×17<sup>''n''/2</sup>+3) / 16 if ''n'' is even * The base 19 family 1{6}: Can be written as (4×19<sup>''n''</sup>−1)/3, it is divisible by 5 if ''n'' is odd and can be factored as (2×19<sup>''n''/2</sup>−1) × (2×19<sup>''n''/2</sup>+1) / 3 if ''n'' is even By the [[:w:Prime number theorem|prime number theorem]], the [[:w:Probability|chance]] that a [[:w:Random number|random]] ''n''-digit base ''b'' number is prime is [[:w:Asymptotic analysis|approximately]] 1/''n'' (more accurately, the chance is approximately 1/(''n''×''ln''(''b'')), where ''ln'' is the [[:w:Natural logarithm|natural logarithm]]). If one conjectures the numbers ''x''{''y''}''z'' behave similarly (i.e. the numbers ''x''{''y''}''z'' is a [[:w:Pseudorandomness|pseudorandom sequence]]) you would expect [[:w:Harmonic_series (mathematics)|1/1 + 1/2 + 1/3 + 1/4 + ... = ∞]] primes of the form ''x''{''y''}''z'' (of course, this does not always happen, since some ''x''{''y''}''z'' families can be ruled out to contain no prime > ''b'' (by covering congruence, algebraic factorization, or combine of them), but it is at least a reasonable conjecture in the absence of evidence to the contrary. Hence, the [[:w:Heuristic argument|heuristic argument]] suggests there are always infinitely many primes in family ''x''{''y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''y'' is a digit in base ''b'') if it cannot be ruled out to contain no prime or only contain finitely many primes, by covering congruence, algebraic factorization, or combine of them. However, some families ''x''{''y''}''z'' could not be proven to contain no primes > ''b'' (by covering congruence, algebraic factorization, or combine of them) but no primes > ''b'' could be found in the family, even after searching through numbers with over 100000 digits. In such a case, the only way to proceed is to [[:w:Primality test|test the primality]] of larger and larger numbers of such form and hope a prime is eventually discovered. e.g. the smallest (probable) prime in the family A{3}A in base ''b'' = 13 is A3<sub>592197</sub>A, which written in decimal contains 659677 digits (it is only probable prime, i.e. not definitely prime).

problem in decimal (base ''b'' = 10) == '''Bold''' for the minimal elements, ''x'' ◁ ''y'' means ''x'' is a subsequence of ''y''. Assume ''p'' is a prime > 10, and the last digit of ''p'' must lie in {1,3,7,9}. Case 1: ''p'' ends with 1. In this case we can write ''p'' = ''x''1. If ''x'' contains 1, 3, 4, 6, or 7, then (respectively) '''11''' ◁ ''p'', '''31''' ◁ ''p'', '''41''' ◁ ''p'', '''61''' ◁ ''p'', or '''71''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 2, 5, 8, or 9. Case 1.1: ''p'' begins with 2. In this case we can write ''p'' = 2''y''1. If 5 ◁ ''y'', then '''251''' ◁ ''p''. If 8 ◁ ''y'', then '''281''' ◁ ''p''. If 9 ◁ ''y'', then 29 ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 2. If 22 ◁ ''y'', then '''2221''' ◁ ''p''. Hence we may assume ''y'' contains zero or one 2's. If ''y'' contains no 2's, then ''p'' ∈ 2{0}1. But then, since the sum of the digits of ''p'' is 3, ''p'' is divisible by 3, so ''p'' cannot be prime. If ''y'' contains exactly one 2, then we can write ''p'' = 2''z''2''w''1, where ''z'',''w'' ∈ {0}. If 0 ◁ ''z'' and 0 ◁ ''w'', then '''20201''' ◁ ''p''. Hence we may assume either ''z'' or ''w'' is empty. If ''z'' is empty, then ''p'' ∈ 22{0}1, and the smallest prime ''p'' ∈ 22{0}1 is '''22000001'''. If ''w'' is empty, then ''p'' ∈ 2{0}21, and the smallest prime ''p'' ∈ 2{0}21 is '''20021'''. Case 1.2: ''p'' begins with 5. In this case we can write ''p'' = 5''y''1. If 2 ◁ ''y'', then '''521''' ◁ ''p''. If 9 ◁ ''y'', then 59 ◁ ''p''. Hence we may assume all digits of ''y'' are 0, 5, or 8. If 05 ◁ ''y'', then '''5051''' ◁ ''p''. If 08 ◁ ''y'', then '''5081''' ◁ ''p''. If 50 ◁ ''y'', then '''5501''' ◁ ''p''. If 58 ◁ ''y'', then '''5581''' ◁ ''p''. If 80 ◁ ''y'', then '''5801''' ◁ ''p''. If 85 ◁ ''y'', then '''5851''' ◁ ''p''. Hence we may assume ''y'' ∈ {0} ∪ {5} ∪ {8}. If ''y'' ∈ {0}, then ''p'' ∈ 5{0}1. But then, since the sum of the digits of ''p'' is 6, ''p'' is divisible by 3, so ''p'' cannot be prime. If ''y'' ∈ {5}, then ''p'' ∈ 5{5}1, and the smallest prime ''p'' ∈ 5{5}1 is '''555555555551'''. If ''y'' ∈ {8}, since if 88 ◁ ''y'', then 881 ◁ ''p'', hence we may assume ''y'' ∈ {''𝜆'',8}, and thus ''p'' ∈ {51,581}, but 51 and 581 are both composite. Case 1.3: ''p'' begins with 8. In this case we can write p = 8''y''1. If 2 ◁ ''y'', then '''821''' ◁ ''p''. If 8 ◁ ''y'', then '''881''' ◁ ''p''. If 9 ◁ ''y'', then 89 ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 5. If 50 ◁ ''y'', then '''8501''' ◁ ''p''. Hence we may assume y ∈ {0}{5}. If 005 ◁ ''y'', then '''80051''' ◁ p. Hence we may assume y ∈ {0} ∪ {5} ∪ 0{5}. If y ∈ {0}, then ''p'' ∈ 8{0}1. But then, since the sum of the digits of ''p'' is 9, ''p'' is divisible by 3, so ''p'' cannot be prime. If y ∈ {5}, since if 55555555555 ◁ ''y'', then 555555555551 ◁ ''p'', hence we may assume ''y'' ∈ {''𝜆'', 5, 55, 555, 5555, 55555, 555555, 5555555, 55555555, 555555555, 5555555555}, and thus ''p'' ∈ {81, 851, 8551, 85551, 855551, 8555551, 85555551, 855555551, 8555555551, 85555555551, 855555555551}, but all of these numbers are composite. If y ∈ 0{5}, since if 55555555555 ◁ ''y'', then 555555555551 ◁ ''p'', hence we may assume ''y'' ∈ {0, 05, 055, 0555, 05555, 055555, 0555555, 05555555, 055555555, 0555555555, 05555555555}, and thus ''p'' ∈ {801, 8051, 80551, 805551, 8055551, 80555551, 805555551, 8055555551, 80555555551, 805555555551, 8055555555551}, and of these numbers only 80555551 and 8055555551 are primes, but 80555551 ◁ 8055555551, thus only '''80555551''' is a minimal element. Case 1.4: ''p'' begins with 9. In this case we can write p = 9''y''1. If 9 ◁ ''y'', then '''991''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0, 2, 5, or 8. If 00 ◁ ''y'', then '''9001''' ◁ ''p''. If 22 ◁ ''y'', then '''9221''' ◁ ''p''. If 55 ◁ ''y'', then '''9551''' ◁ ''p''. If 88 ◁ ''y'', then 881 ◁ ''p''. Hence we may assume ''y'' contains at most one 0, at most one 2, at most one 5, and at most one 8. If ''y'' only contains at most one 0 and does not contain any of {2,5,8}, then ''y'' ∈ {''𝜆'',0}, and thus ''p'' ∈ {91,901}, but 91 and 901 are both composite. If ''y'' only contains at most one 0 and only one of {2,5,8}, then the sum of the digits of ''p'' is divisible by 3, ''p'' is divisible by 3, so ''p'' cannot be prime. Hence we may assume ''y'' contains at least two of {2,5,8}. If 25 ◁ ''y'', then 251 ◁ ''p''. If 28 ◁ ''y'', then 281 ◁ ''p''. If 52 ◁ ''y'', then 521 ◁ ''p''. If 82 ◁ ''y'', then 821 ◁ ''p''. Hence we may assume ''y'' contains no 2's (since if ''y'' contains 2, then ''y'' cannot contain either 5's or 8's, which is a contradiction). If 85 ◁ ''y'', then '''9851''' ◁ ''p''. Hence we may assume ''y'' ∈ {58,580,508,058}, and thus ''p'' ∈ {9581,95801,95081,90581}, and of these numbers only 95801 is prime, but 95801 is not a minimal element since 5801 ◁ 95801. Case 2: ''p'' ends with 3. In this case we can write p = ''x''3. If ''x'' contains 1, 2, 4, 5, 7, or 8, then (respectively) '''13''' ◁ ''p'', '''23''' ◁ ''p'', '''43''' ◁ ''p'', '''53''' ◁ ''p'', '''73''' ◁ ''p'', or '''83''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 3, 6, or 9, and thus all digits of ''p'' are 0, 3, 6, or 9. But then, since the digits of ''p'' all have a common factor 3, ''p'' is divisible by 3, so ''p'' cannot be prime. Case 3: ''p'' ends with 7. In this case we can write ''p'' = ''x''7. If ''x'' contains 1, 3, 4, 6, or 9, then (respectively) '''17''' ◁ ''p'', '''37''' ◁ ''p'', '''47''' ◁ ''p'', '''67''' ◁ ''p'', or '''97''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 2, 5, 7, or 8. Case 3.1: ''p'' begins with 2. In this case we can write ''p'' = 2''y''7. If 2 ◁ ''y'', then '''227''' ◁ ''p''. If 5 ◁ ''y'', then '''257''' ◁ ''p''. If 7 ◁ ''y'', then '''277''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 8. If 08 ◁ ''y'', then '''2087''' ◁ ''p''. If 88 ◁ ''y'', then 887 ◁ ''p''. Hence we may assume ''y'' ∈ {0} ∪ 8{0}. If ''y'' ∈ {0}, then ''p'' ∈ 2{0}7. But then, since the sum of the digits of ''p'' is 9, ''p'' is divisible by 3, so ''p'' cannot be prime. If y ∈ 8{0}, then ''p'' ∈ 28{0}7. But then ''p'' is divisible by 7, since for ''n'' ≥ 0 we have 7 × 40<sub>''n''</sub>1 = 280<sub>''n''</sub>7. Case 3.2: ''p'' begins with 5. In this case we can write ''p'' = 5''y''7. If 5 ◁ ''y'', then '''557''' ◁ ''p''. If 7 ◁ ''y'', then '''577''' ◁ ''p''. If 8 ◁ ''y'', then '''587''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 2. If 22 ◁ ''y'', then 227 ◁ ''p''. Hence we may assume ''y'' contains zero or one 2's. If ''y'' contains no 2's, then ''p'' ∈ 5{0}7. But then, since the sum of the digits of ''p'' is 12, ''p'' is divisible by 3, so ''p'' cannot be prime. If ''y'' contains exactly one 2, then we can write ''p'' = 5''z''2''w''7, where ''z'',''w'' ∈ {0}. If 0 ◁ ''z'' and 0 ◁ ''w'', then '''50207''' ◁ ''p''. Hence we may assume either ''z'' or ''w'' is empty. If ''z'' is empty, then ''p'' ∈ 52{0}7, and the smallest prime ''p'' ∈ 52{0}7 is '''5200007'''. If ''w'' is empty, then ''p'' ∈ 5{0}27, and the smallest prime ''p'' ∈ 5{0}27 is '''5000000000000000000000000000027'''. Case 3.3: ''p'' begins with 7. In this case we can write ''p'' = 7''y''7. If 2 ◁ ''y'', then '''727''' ◁ ''p''. If 5 ◁ ''y'', then '''757''' ◁ ''p''. If 8 ◁ ''y'', then '''787''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 7, and thus all digits of ''p'' are 0 or 7. But then, since the digits of ''p'' all have a common factor 7, ''p'' is divisible by 7, so ''p'' cannot be prime. Case 3.4: ''p'' begins with 8. In this case we can write ''p'' = 8''y''7. If 2 ◁ ''y'', then '''827''' ◁ ''p''. If 5 ◁ ''y'', then '''857''' ◁ ''p''. If 7 ◁ ''y'', then '''877''' ◁ ''p''. If 8 ◁ ''y'', then '''887''' ◁ ''p''. Hence we may assume ''y'' ∈ {0}, and thus ''p'' ∈ 8{0}7. But then, since the sum of the digits of ''p'' is 15, ''p'' is divisible by 3, so ''p'' cannot be prime. Case 4: ''p'' ends with 9. In this case we can write ''p'' = ''x''9. If ''x'' contains 1, 2, 5, 7, or 8, then (respectively) '''19''' ◁ ''p'', '''29''' ◁ ''p'', '''59''' ◁ ''p'', '''79''' ◁ ''p'', or '''89''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 3, 4, 6, or 9. If 44 ◁ ''x'', then '''449''' ◁ ''p''. Hence we may assume ''x'' contains zero or one 4's. If x contains no 4's, then all digits of ''x'' are 0, 3, 6, or 9, and thus all digits of ''p'' are 0, 3, 6, or 9. But then, since the digits of ''p'' all have a common factor 3, ''p'' is divisible by 3, so ''p'' cannot be prime. Hence we may assume that ''x'' contains exactly one 4. Case 4.1: ''p'' begins with 3. In this case we can write ''p'' = 3''y''4''z''9, where all digits of ''y'', ''z'' are 0, 3, 6, or 9. We must have '''349''' ◁ ''p''. Case 4.2: ''p'' begins with 4. In this case we can write ''p'' = 4''y''9, where all digits of ''y'' are 0, 3, 6, or 9. If 0 ◁ ''y'', then '''409''' ◁ ''p''. If 3 ◁ ''y'', then 43 ◁ ''p''. If 9 ◁ ''y'', then '''499''' ◁ ''p''. Hence we may assume ''y'' ∈ {6}, and thus ''p'' ∈ 4{6}9. But then ''p'' is divisible by 7, since for ''n'' ≥ 0 we have 7 × 6<sub>''n''</sub>7 = 46<sub>''n''</sub>9. Case 4.3: ''p'' begins with 6. In this case we can write p = 6''y''4''z''9, where all digits of ''y'', ''z'' are 0, 3, 6, or 9. If 0 ◁ ''z'', then 409 ◁ ''p''. If 3 ◁ ''z'', then 43 ◁ ''p''. If 6 ◁ ''z'', then '''6469''' ◁ ''p''. If 9 ◁ ''z'', then 499 ◁ ''p''. Hence we may assume ''z'' is empty. If 3 ◁ ''y'', then 349 ◁ ''p''. If 9 ◁ ''y'', then '''6949''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 6. If 06 ◁ ''y'', then '''60649''' ◁ ''p''. Hence we may assume ''y'' ∈ {6}{0}. If 666 ◁ ''y'', then '''666649''' ◁ ''p''. If 00000 ◁ ''y'', then '''60000049''' ◁ ''p''. Hence we may assume ''y'' ∈ {''𝜆'', 0, 00, 000, 0000, 6, 60, 600, 6000, 60000, 66, 660, 6600, 66000, 660000}, and thus ''p'' ∈ {649, 6049, 60049, 600049, 6000049, 6649, 66049, 660049, 6600049, 66000049, 66649, 666049, 6660049, 66600049, 666000049}, and of these numbers only '''66000049''' and '''66600049''' are primes. Case 4.4: ''p'' begins with 9. In this case we can write p = 9''y''4''z''9, where all digits of ''y'', ''z'' are 0, 3, 6, or 9. If 0 ◁ ''y'', then '''9049''' ◁ ''p''. If 3 ◁ ''y'', then 349 ◁ ''p''. If 6 ◁ ''y'', then '''9649''' ◁ ''p''. If 9 ◁ ''y'', then '''9949''' ◁ ''p''. Hence we may assume ''y'' is empty. If 0 ◁ ''z'', then 409 ◁ ''p''. If 3 ◁ ''z'', then 43 ◁ ''p''. If 9 ◁ ''z'', then 499 ◁ ''p''. Hence we may assume ''z'' ∈ {6}, and thus ''p'' ∈ 94{6}9, and the smallest prime ''p'' ∈ 94{6}9 is 946669.

Athena problem is: Give a [[:w:Natural number|natural number]] ''b'' > 1, find the [[:w:Set (mathematics)|set]] of the [[:w:Minimal element|minimal element]]s of the set of the "[[:w:Prime number|prime number]] [[:w:Greater than|>]] ''b''" [[:w:Numerical digit|digit]] [[:w:String (computer science)|string]]s in the [[:w:Positional numeral system|positional numeral system]] with [[:w:Radix|base]] ''b'' for the [[:w:Subsequence|subsequence]] [[:w:Partially ordered set|ordering]]. (A string ''x'' is a subsequence of another string ''y'', if ''x'' can be obtained from ''y'' by deleting zero or more of the [[:w:Character (computing)|character]]s in ''y''. For example, 514 is a subsequence of 352148, "string" is a subsequence of "meistersinger". In contrast, 758 is not a subsequence of 378259, "abc" is not a subsequence of "cbacacba", since the characters must be in the same order) (Unlike [[:w:Substring|substring]], subsequence is not required to occupy consecutive positions within the original sequences, e.g. the [[:w:Longest common subsequence|longest common subsequence problem]] is different from the [[:w:Longest common substring|longest common substring problem]]) Using [[:w:Formal language theory|formal language theory]] terminology, Athena problem is finding the [[:w:Set (mathematics)|set]] of the [[:w:Minimal element|minimal element]]s of the [[:w:Formal language|language]] of base-''b'' [[:w:Representation (mathematics)|representation]]s of the [[:w:Prime number|prime number]]s [[:w:Greater than|>]] ''b'' (which is a set of [[:w:String (computer science)|string]]s of [[:w:Symbol|symbol]]s over the [[:w:Alphabet (formal languages)|alphabet]] ''Σ''<sub>''b''</sub> := {0, 1, ..., ''b''−1}), under the subsequence ordering (i.e. the [[:w:Binary relation|binary relation]] "is a subsequence of", which is a [[:w:Partially ordered set|partial ordering]]), for a given natural number ''b'' > 1. (You can draw this ordering as [[:w:Hasse diagram|Hasse diagram]] to find all [[:w:Minimal element|minimal element]]s) By [[:w:Higman's lemma|Higman's lemma]], there are no [[:w:Infinite set|infinite]] [[:w:Antichain|antichain]]s for the subsequence ordering (i.e. the subsequence ordering is always a [[:w:Well-quasi-ordering|well quasi order]]) (i.e. under the subsequence ordering (i.e. the [[:w:Binary relation|binary relation]] "is a subsequence of", which is a [[:w:Partially ordered set|partial ordering]]), every set of pairwise incomparable (i.e. not [[:w:Comparability|comparable]]) strings is finite), thus there must be only finitely many such minimal elements. In other words, the set of such minimal elements must be a [[:w:Finite set|finite set]], e.g. in [[:w:Decimal|decimal]] (base ''b'' = 10), this set has exactly 77 [[:w:Element of a set|element]]s: {11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 227, 251, 257, 277, 281, 349, 409, 449, 499, 521, 557, 577, 587, 727, 757, 787, 821, 827, 857, 877, 881, 887, 991, 2087, 2221, 5051, 5081, 5501, 5581, 5801, 5851, 6469, 6949, 8501, 9001, 9049, 9221, 9551, 9649, 9851, 9949, 20021, 20201, 50207, 60649, 80051, 666649, 946669, 5200007, 22000001, 60000049, 66000049, 66600049, 80555551, 555555555551, 5000000000000000000000000000027}. For bases 2 ≤ ''b'' ≤ 36, Athena problem is fully solved in bases ''b'' = 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 14, 15, 18, 20, 24, and also solved in bases ''b'' = 11, 13, 16, 22, 30 if [[:w:Probable prime|probable prime]]s are allowed. For the unsolved bases ''b'' = 17, 19, 21, 23, 25, 26, 27, 28, 29, 31, 32, 34, 35, 36, Athena problem is solved (if probable primes are allowed) except 771 [[:w:Indexed family|families]] of the form ''x''{''y''}''z'' (where ''x'' and ''z'' are strings (may be [[:w:Empty string|empty]]) of digits in base ''b'', ''y'' is a digit in base ''b'') = sequence {''xz'', ''xyz'', ''xyyz'', ''xyyyz'', ''xyyyyz'', ''xyyyyyz'', ...} (i.e. "''xy''<sup>+</sup>''z''" in [[:w:Regular expression|regular expression]]), all of these 771 families contain no primes or probable primes with length ≤ 100000. == Results == These are the results of the Athena problem in bases 2 ≤ ''b'' ≤ 36 (we stop at base 36 since this base is the maximum base for which it is possible to write the numbers with the [[:w:Symbol|symbol]]s 0, 1, 2, ..., 9 and A, B, C, ..., Z (i.e. the 10 [[:w:Arabic numerals|Arabic numerals]] and the 26 [[:w:Latin script|Latin letters]]): (some large primes are only probable primes, i.e. not definitely primes, since they are too large to be [[:w:Elliptic curve primality|ECPP proved]] and [[:w:Pocklington primality test#Extensions and variants|neither ''N''−1 nor ''N''+1 can be ≥ 1/3 factored]], all of them pass the [[:w:Baillie–PSW primality test|Baillie–PSW primality test]] and the [[:w:Strong pseudoprime|strong primality test]] (i.e. the [[:w:Miller–Rabin primality test|Miller–Rabin primality test]]) with all prime bases ''p'' ≤ 61, however, all primes < 10<sup>25000</sup> for bases ''b'' = 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 18, 20, 22, 24, 26, 28, 30, 36 are definitely primes, most of them > 10<sup>299</sup> are proven primes with [[:w:Elliptic curve primality|ECPP proving]], others > 10<sup>299</sup> are proven primes with [[:w:Pocklington primality test#Extensions and variants|''N''−1 or ''N''+1 proving]]) To solve the Athena problem for a given base ''b'', we must [[:w:Computing|compute]] the element up to families of the form ''x''{''y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''y'' is a digit in base ''b'') (we call such families ''linear families''), and find the smallest prime > ''b'' in all such families. Shrinking the family ''x''{''Y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''Y'' is a set of digits in base ''b'') * If ''y'' ∈ ''Y'' and the string ''xyyz'' represents a prime > ''b'' in base ''b'' (in this case, add this prime to the list) or has a subsequence which represents a prime > ''b'' in base ''b'', then ''x''{''Y''}''z'' can be replaced with ''x''{''Y'' \ ''y''}''z'' ∪ ''x''{''Y'' \ ''y''}''y''{''Y'' \ ''y''}''z''. * If ''y''<sub>1</sub> ∈ ''Y'' and ''y''<sub>2</sub> ∈ ''Y'' and ''y''<sub>1</sub> ≠ ''y''<sub>2</sub> and the string ''xy''<sub>1</sub>''y''<sub>2</sub>''z'' represents a prime > ''b'' in base ''b'' (in this case, add this prime to the list) or has a subsequence which represents a prime > ''b'' in base ''b'', then ''x''{''Y''}''z'' can be replaced with ''x''{''Y'' \ ''y''<sub>1</sub>}{''Y'' \ ''y''<sub>2</sub>}''z''. * If ''y''<sub>1</sub> ∈ ''Y'' and ''y''<sub>2</sub> ∈ ''Y'' and ''y''<sub>1</sub> ≠ ''y''<sub>2</sub> and both the strings ''xy''<sub>1</sub>''y''<sub>2</sub>''z'' and ''xy''<sub>2</sub>''y''<sub>1</sub>''z'' represent a prime > ''b'' in base ''b'' (in this case, add this prime to the list) or have a subsequence which represents a prime > ''b'' in base ''b'', then ''x''{''Y''}''z'' can be replaced with ''x''{''Y'' \ ''y''<sub>1</sub>}''z'' ∪ ''x''{''Y'' \ ''y''<sub>2</sub>}''z''. e.g. in decimal (base ''b'' = 10): * 2221 is a prime > 10, thus the family 2{0,2}1 splits into the two families 2{0}1 and 2{0}2{0}1. * 227 is a prime > 10, and it is a subsequence of 5227, thus the family 5{0,2}7 splits into the two families 5{0}7 and 5{0}2{0}7. * 449 is a prime > 10, and it is a subsequence of 6449, thus the family 6{0,3,4,6,9}9 splits into the two families 6{0,3,6,9}9 and 6{0,3,6,9}4{0,3,6,9}9. * Both 5051 and 5501 are primes > 10, thus the family 5{0,5}1 splits into the two families 5{0}1 and 5{5}1 = {5}1. * 8501 is a prime > 10, thus the family 8{0,5}1 splits into the family 8{0}{5}1. * 887 is a prime > 10, and it is a subsequence of 2887, also 2087 is a prime > 10, thus the family 2{0,8}7 splits into the two families 2{0}7 and 28{0}7. * 349 and 449 are primes > 10, and they are subsequences of 9349 and 9449, respectively, also 9049, 9649, 9949 are primes > 10, thus the family 9{0,3,4,6,9}9 splits into the two families 9{0,3,6,9}9 and 94{0,3,6,9}9. * 251, 281, 521, 821, 881 are primes > 10, and they are subsequences of 9251, 9281, 9521, 9821, 9881, respectively, also 9001, 9221, 9551, 9851 are primes > 10, thus the family 9{0,2,5,8}1 splits into the numbers {91, 901, 921, 951, 981, 9021, 9051, 9081, 9201, 9501, 9581, 9801, 90581, 95081, 95801}. If the methods we have discussed cannot be used to rule out or shrink ''x''{''Y''}''z'' where ''Y'' = {''y''<sub>1</sub>, ''y''<sub>2</sub>, ..., ''y''<sub>''n''</sub>}, then we can replace ''x''{''Y''}''z'' by ''xy''<sub>1</sub>{''Y''}''z'' ∪ ''xy''<sub>2</sub>{''Y''}''z'' ∪ ... ∪ ''xy''<sub>''n''</sub>{''Y''}''z'' and re-run the methods on this new [[:w:Formal language|language]]. If all remain families are linear families (i.e. of the form ''x''{''y''}''z'', where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''y'' is a digit in base ''b''), then we search the smallest (probable) primes in these families and add these primes to the list. e.g. in decimal (base ''b'' = 10): * The smallest prime in the family 5{0}27 is 5000000000000000000000000000027. * The smallest prime in the family {5}1 is 555555555551. * The smallest prime in the family 8{5}1 is 8555555555555555555551, but 8555555555555555555551 is not a minimal element since 555555555551 is a subsequence of 8555555555555555555551. There is no guarantee that the techniques discussed will ever terminate, but in practice they often do. They are able to determine the set of the minimal elements in base ''b'' for 2 ≤ ''b'' ≤ 16 and ''b'' = 18, 20, 22, 24, 30. The bases ''b'' = 17, 19, 21, 23, 25 ≤ ''b'' ≤ 29, 31 ≤ ''b'' ≤ 36 are solved with the exception of 771 families of the form ''x''{''y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''y'' is a digit in base ''b''). The following is a "[[:w:Semi-algorithm|semi-algorithm]]" that is guaranteed to solve the Athena problem for a given base ''b'', but it is not so easy to implement: # ''M'' = ''[[:w:Empty string|∅]]'' # while (''L'' ≠ ''∅'') do # choose ''x'', a shortest string in ''L'' # ''M'' := ''M'' ∪ {''x''} # ''L'' := ''L'' − ''sup''({''x''}) In practice, for arbitrary ''L'', we cannot feasibly carry out step 5. Instead, we work with ''L''&#39;, some regular overapproximation to ''L'', until we can show ''L''&#39; = ''∅'' (which implies ''L'' = ''∅''). In practice, ''L''&#39; is usually chosen to be a finite [[:w:Union (set theory)|union]] of sets of the form ''L''<sub>1</sub>{''L''<sub>2</sub>}''L''<sub>3</sub>, where each of ''L''<sub>1</sub>, ''L''<sub>2</sub>, ''L''<sub>3</sub> is finite. In the case we consider in this project, we then have to determine whether such a family contains a prime or not. Thus, Athena problem in bases ''b'' around 500 may be [[:w:NP-complete|NP-complete]] or [[:w:NP-hard|NP-hard]], or an [[:w:Undecidable problem|undecidable problem]], or an example of [[:w:Gödel's incompleteness theorems|Gödel's incompleteness theorems]] (like the [[:w:Continuum hypothesis|continuum hypothesis]] and the [[:w:Halting problem|halting problem]]). To solve the Athena problem, we need to determine whether a given family contains a prime. In practice, if family ''x''{''Y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''Y'' is a set of digits in base ''b'') could not be ruled out as only containing composites and ''Y'' contains two or more digits, then a relatively small prime > ''b'' could always be found in this family. Intuitively, this is because there are a large number of small strings in such a family, and at least one is likely to be prime (e.g. there are 2<sup>''n''−2</sup> strings of length ''n'' in the family 1{3,7}9, and there are over a thousand strings of length 12 in the family 1{3,7}9, thus it is very impossible that these numbers are all composite). In the case ''Y'' contains only one digit, this family is of the form ''x''{''y''}''z'', and there is only a single string of each length > (the length of ''x'' + the length of ''z''), and it is not known if the following [[:w:Decision problem|decision problem]] is recursively solvable (just like [[:w:Sierpiński number|Sierpiński problem]] and [[:w:Riesel number|Riesel problem]], Sierpiński problem and Riesel problem can be generalized to other bases ''b'', in fact, Athena problem in base ''b'' covers the Sierpiński problem in base ''b'' and the Riesel problem in base ''b'' with ''k'' < ''b'', i.e. finding the smallest prime of the form ''k''×''b''<sup>''n''</sup>+1 and ''k''×''b''<sup>''n''</sup>−1 (or prove such prime does not exist) with ''k'' < ''b'', since the smallest prime of the form ''k''×''b''<sup>''n''</sup>+1 and ''k''×''b''<sup>''n''</sup>−1 (if exists) must be a minimal element in base ''b''): Problem: Given strings ''x'', ''z'' (may be empty), a digit ''y'', and a base ''b'' (''x'' does not [[:w:Leading zero|start with the digit 0]], ''z'' ends with a digit which [[:w:Coprime integers|coprime]] to ''b'', ''y'' is not 0 if ''x'' is empty, ''y'' is coprime to ''b'' if ''z'' is empty), does there exist a prime number whose base-''b'' expansion is of the form ''xy''<sub>''n''</sub>''z'' for some ''n'' ≥ 0? Some families can be ruled out to contain no prime > ''b'' by [[:w:Covering set|covering congruence]], [[:w:Factorization of polynomials|algebraic factorization]] (e.g. [[:w:Difference of two squares|difference of two squares]], [[:w:Sum of two cubes|sum of two cubes]], [[:w:Sophie Germain's identity|Sophie Germain's identity of ''x''<sup>4</sup>+4×''y''<sup>4</sup>]]), or combine of them, e.g. * The base 9 family 2{7}: Always divisible by 2 or 5 * The base 16 family {8}F: Always divisible by 3, 7, or 13 * The base 21 family {7}D: Always divisible by 2, 13, or 17 * The base 23 family {D}GA: Always divisible by 2, 5, 7, 37, or 79 * The base 9 family 3{8}: Can be written as 4×9<sup>''n''</sup>−1 and can be factored as (2×3<sup>''n''</sup>−1) × (2×3<sup>''n''</sup>+1) * The base 8 family 1{0}1: Can be written as 8<sup>''n''</sup>+1 and can be factored as (2<sup>''n''</sup>+1) × (4<sup>''n''</sup>−2<sup>''n''</sup>+1) * The base 16 family {4}1: Can be written as (4×16<sup>''n''</sup>−49)/15 and can be factored as (2×3<sup>''n''</sup>−7) × (2×3<sup>''n''</sup>+7) / 15 * The base 16 family {C}D: Can be written as (4×16<sup>''n''</sup>+1)/5 and can be factored as (2×4<sup>''n''</sup>−2×2<sup>''n''</sup>+1) × (2×4<sup>''n''</sup>+2×2<sup>''n''</sup>+1) / 5 * The base 14 family 8{D}: Can be written as 9×14<sup>''n''</sup>−1, it is divisible by 5 if ''n'' is odd and can be factored as (3×14<sup>''n''/2</sup>−1) × (3×14<sup>''n''/2</sup>+1) if ''n'' is even * The base 12 family {B}9B: Can be written as 12<sup>''n''</sup>−25, it is divisible by 13 if ''n'' is odd and can be factored as (12<sup>''n''/2</sup>−5) × (12<sup>''n''/2</sup>+5) if ''n'' is even * The base 17 family 1{9}: Can be written as (25×17<sup>''n''</sup>−9)/16, it is divisible by 2 if ''n'' is odd and can be factored as (5×17<sup>''n''/2</sup>−3) × (5×17<sup>''n''/2</sup>+3) / 16 if ''n'' is even * The base 19 family 1{6}: Can be written as (4×19<sup>''n''</sup>−1)/3, it is divisible by 5 if ''n'' is odd and can be factored as (2×19<sup>''n''/2</sup>−1) × (2×19<sup>''n''/2</sup>+1) / 3 if ''n'' is even By the [[:w:Prime number theorem|prime number theorem]], the [[:w:Probability|chance]] that a [[:w:Random number|random]] ''n''-digit base ''b'' number is prime is [[:w:Asymptotic analysis|approximately]] 1/''n'' (more accurately, the chance is approximately 1/(''n''×''ln''(''b'')), where ''ln'' is the [[:w:Natural logarithm|natural logarithm]]). If one conjectures the numbers ''x''{''y''}''z'' behave similarly (i.e. the numbers ''x''{''y''}''z'' is a [[:w:Pseudorandomness|pseudorandom sequence]]) you would expect [[:w:Harmonic_series (mathematics)|1/1 + 1/2 + 1/3 + 1/4 + ... = ∞]] primes of the form ''x''{''y''}''z'' (of course, this does not always happen, since some ''x''{''y''}''z'' families can be ruled out to contain no prime > ''b'' (by covering congruence, algebraic factorization, or combine of them), but it is at least a reasonable conjecture in the absence of evidence to the contrary. Hence, the [[:w:Heuristic argument|heuristic argument]] suggests there are always infinitely many primes in family ''x''{''y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''y'' is a digit in base ''b'') if it cannot be ruled out to contain no prime or only contain finitely many primes, by covering congruence, algebraic factorization, or combine of them. However, some families ''x''{''y''}''z'' could not be proven to contain no primes > ''b'' (by covering congruence, algebraic factorization, or combine of them) but no primes > ''b'' could be found in the family, even after searching through numbers with over 100000 digits. In such a case, the only way to proceed is to [[:w:Primality test|test the primality]] of larger and larger numbers of such form and hope a prime is eventually discovered. e.g. the smallest (probable) prime in the family A{3}A in base ''b'' = 13 is A3<sub>592197</sub>A, which written in decimal contains 659677 digits (it is only probable prime, i.e. not definitely prime).

problem in decimal (base ''b'' = 10) == '''Bold''' for the minimal elements, ''x'' ◁ ''y'' means ''x'' is a subsequence of ''y''. Assume ''p'' is a prime > 10, and the last digit of ''p'' must lie in {1,3,7,9}. Case 1: ''p'' ends with 1. In this case we can write ''p'' = ''x''1. If ''x'' contains 1, 3, 4, 6, or 7, then (respectively) '''11''' ◁ ''p'', '''31''' ◁ ''p'', '''41''' ◁ ''p'', '''61''' ◁ ''p'', or '''71''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 2, 5, 8, or 9. Case 1.1: ''p'' begins with 2. In this case we can write ''p'' = 2''y''1. If 5 ◁ ''y'', then '''251''' ◁ ''p''. If 8 ◁ ''y'', then '''281''' ◁ ''p''. If 9 ◁ ''y'', then 29 ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 2. If 22 ◁ ''y'', then '''2221''' ◁ ''p''. Hence we may assume ''y'' contains zero or one 2's. If ''y'' contains no 2's, then ''p'' ∈ 2{0}1. But then, since the sum of the digits of ''p'' is 3, ''p'' is divisible by 3, so ''p'' cannot be prime. If ''y'' contains exactly one 2, then we can write ''p'' = 2''z''2''w''1, where ''z'',''w'' ∈ {0}. If 0 ◁ ''z'' and 0 ◁ ''w'', then '''20201''' ◁ ''p''. Hence we may assume either ''z'' or ''w'' is empty. If ''z'' is empty, then ''p'' ∈ 22{0}1, and the smallest prime ''p'' ∈ 22{0}1 is '''22000001'''. If ''w'' is empty, then ''p'' ∈ 2{0}21, and the smallest prime ''p'' ∈ 2{0}21 is '''20021'''. Case 1.2: ''p'' begins with 5. In this case we can write ''p'' = 5''y''1. If 2 ◁ ''y'', then '''521''' ◁ ''p''. If 9 ◁ ''y'', then 59 ◁ ''p''. Hence we may assume all digits of ''y'' are 0, 5, or 8. If 05 ◁ ''y'', then '''5051''' ◁ ''p''. If 08 ◁ ''y'', then '''5081''' ◁ ''p''. If 50 ◁ ''y'', then '''5501''' ◁ ''p''. If 58 ◁ ''y'', then '''5581''' ◁ ''p''. If 80 ◁ ''y'', then '''5801''' ◁ ''p''. If 85 ◁ ''y'', then '''5851''' ◁ ''p''. Hence we may assume ''y'' ∈ {0} ∪ {5} ∪ {8}. If ''y'' ∈ {0}, then ''p'' ∈ 5{0}1. But then, since the sum of the digits of ''p'' is 6, ''p'' is divisible by 3, so ''p'' cannot be prime. If ''y'' ∈ {5}, then ''p'' ∈ 5{5}1, and the smallest prime ''p'' ∈ 5{5}1 is '''555555555551'''. If ''y'' ∈ {8}, since if 88 ◁ ''y'', then 881 ◁ ''p'', hence we may assume ''y'' ∈ {''𝜆'',8}, and thus ''p'' ∈ {51,581}, but 51 and 581 are both composite. Case 1.3: ''p'' begins with 8. In this case we can write p = 8''y''1. If 2 ◁ ''y'', then '''821''' ◁ ''p''. If 8 ◁ ''y'', then '''881''' ◁ ''p''. If 9 ◁ ''y'', then 89 ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 5. If 50 ◁ ''y'', then '''8501''' ◁ ''p''. Hence we may assume y ∈ {0}{5}. If 005 ◁ ''y'', then '''80051''' ◁ p. Hence we may assume y ∈ {0} ∪ {5} ∪ 0{5}. If y ∈ {0}, then ''p'' ∈ 8{0}1. But then, since the sum of the digits of ''p'' is 9, ''p'' is divisible by 3, so ''p'' cannot be prime. If y ∈ {5}, since if 55555555555 ◁ ''y'', then 555555555551 ◁ ''p'', hence we may assume ''y'' ∈ {''𝜆'', 5, 55, 555, 5555, 55555, 555555, 5555555, 55555555, 555555555, 5555555555}, and thus ''p'' ∈ {81, 851, 8551, 85551, 855551, 8555551, 85555551, 855555551, 8555555551, 85555555551, 855555555551}, but all of these numbers are composite. If y ∈ 0{5}, since if 55555555555 ◁ ''y'', then 555555555551 ◁ ''p'', hence we may assume ''y'' ∈ {0, 05, 055, 0555, 05555, 055555, 0555555, 05555555, 055555555, 0555555555, 05555555555}, and thus ''p'' ∈ {801, 8051, 80551, 805551, 8055551, 80555551, 805555551, 8055555551, 80555555551, 805555555551, 8055555555551}, and of these numbers only 80555551 and 8055555551 are primes, but 80555551 ◁ 8055555551, thus only '''80555551''' is a minimal element. Case 1.4: ''p'' begins with 9. In this case we can write p = 9''y''1. If 9 ◁ ''y'', then '''991''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0, 2, 5, or 8. If 00 ◁ ''y'', then '''9001''' ◁ ''p''. If 22 ◁ ''y'', then '''9221''' ◁ ''p''. If 55 ◁ ''y'', then '''9551''' ◁ ''p''. If 88 ◁ ''y'', then 881 ◁ ''p''. Hence we may assume ''y'' contains at most one 0, at most one 2, at most one 5, and at most one 8. If ''y'' only contains at most one 0 and does not contain any of {2,5,8}, then ''y'' ∈ {''𝜆'',0}, and thus ''p'' ∈ {91,901}, but 91 and 901 are both composite. If ''y'' only contains at most one 0 and only one of {2,5,8}, then the sum of the digits of ''p'' is divisible by 3, ''p'' is divisible by 3, so ''p'' cannot be prime. Hence we may assume ''y'' contains at least two of {2,5,8}. If 25 ◁ ''y'', then 251 ◁ ''p''. If 28 ◁ ''y'', then 281 ◁ ''p''. If 52 ◁ ''y'', then 521 ◁ ''p''. If 82 ◁ ''y'', then 821 ◁ ''p''. Hence we may assume ''y'' contains no 2's (since if ''y'' contains 2, then ''y'' cannot contain either 5's or 8's, which is a contradiction). If 85 ◁ ''y'', then '''9851''' ◁ ''p''. Hence we may assume ''y'' ∈ {58,580,508,058}, and thus ''p'' ∈ {9581,95801,95081,90581}, and of these numbers only 95801 is prime, but 95801 is not a minimal element since 5801 ◁ 95801. Case 2: ''p'' ends with 3. In this case we can write p = ''x''3. If ''x'' contains 1, 2, 4, 5, 7, or 8, then (respectively) '''13''' ◁ ''p'', '''23''' ◁ ''p'', '''43''' ◁ ''p'', '''53''' ◁ ''p'', '''73''' ◁ ''p'', or '''83''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 3, 6, or 9, and thus all digits of ''p'' are 0, 3, 6, or 9. But then, since the digits of ''p'' all have a common factor 3, ''p'' is divisible by 3, so ''p'' cannot be prime. Case 3: ''p'' ends with 7. In this case we can write ''p'' = ''x''7. If ''x'' contains 1, 3, 4, 6, or 9, then (respectively) '''17''' ◁ ''p'', '''37''' ◁ ''p'', '''47''' ◁ ''p'', '''67''' ◁ ''p'', or '''97''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 2, 5, 7, or 8. Case 3.1: ''p'' begins with 2. In this case we can write ''p'' = 2''y''7. If 2 ◁ ''y'', then '''227''' ◁ ''p''. If 5 ◁ ''y'', then '''257''' ◁ ''p''. If 7 ◁ ''y'', then '''277''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 8. If 08 ◁ ''y'', then '''2087''' ◁ ''p''. If 88 ◁ ''y'', then 887 ◁ ''p''. Hence we may assume ''y'' ∈ {0} ∪ 8{0}. If ''y'' ∈ {0}, then ''p'' ∈ 2{0}7. But then, since the sum of the digits of ''p'' is 9, ''p'' is divisible by 3, so ''p'' cannot be prime. If y ∈ 8{0}, then ''p'' ∈ 28{0}7. But then ''p'' is divisible by 7, since for ''n'' ≥ 0 we have 7 × 40<sub>''n''</sub>1 = 280<sub>''n''</sub>7. Case 3.2: ''p'' begins with 5. In this case we can write ''p'' = 5''y''7. If 5 ◁ ''y'', then '''557''' ◁ ''p''. If 7 ◁ ''y'', then '''577''' ◁ ''p''. If 8 ◁ ''y'', then '''587''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 2. If 22 ◁ ''y'', then 227 ◁ ''p''. Hence we may assume ''y'' contains zero or one 2's. If ''y'' contains no 2's, then ''p'' ∈ 5{0}7. But then, since the sum of the digits of ''p'' is 12, ''p'' is divisible by 3, so ''p'' cannot be prime. If ''y'' contains exactly one 2, then we can write ''p'' = 5''z''2''w''7, where ''z'',''w'' ∈ {0}. If 0 ◁ ''z'' and 0 ◁ ''w'', then '''50207''' ◁ ''p''. Hence we may assume either ''z'' or ''w'' is empty. If ''z'' is empty, then ''p'' ∈ 52{0}7, and the smallest prime ''p'' ∈ 52{0}7 is '''5200007'''. If ''w'' is empty, then ''p'' ∈ 5{0}27, and the smallest prime ''p'' ∈ 5{0}27 is '''5000000000000000000000000000027'''. Case 3.3: ''p'' begins with 7. In this case we can write ''p'' = 7''y''7. If 2 ◁ ''y'', then '''727''' ◁ ''p''. If 5 ◁ ''y'', then '''757''' ◁ ''p''. If 8 ◁ ''y'', then '''787''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 7, and thus all digits of ''p'' are 0 or 7. But then, since the digits of ''p'' all have a common factor 7, ''p'' is divisible by 7, so ''p'' cannot be prime. Case 3.4: ''p'' begins with 8. In this case we can write ''p'' = 8''y''7. If 2 ◁ ''y'', then '''827''' ◁ ''p''. If 5 ◁ ''y'', then '''857''' ◁ ''p''. If 7 ◁ ''y'', then '''877''' ◁ ''p''. If 8 ◁ ''y'', then '''887''' ◁ ''p''. Hence we may assume ''y'' ∈ {0}, and thus ''p'' ∈ 8{0}7. But then, since the sum of the digits of ''p'' is 15, ''p'' is divisible by 3, so ''p'' cannot be prime. Case 4: ''p'' ends with 9. In this case we can write ''p'' = ''x''9. If ''x'' contains 1, 2, 5, 7, or 8, then (respectively) '''19''' ◁ ''p'', '''29''' ◁ ''p'', '''59''' ◁ ''p'', '''79''' ◁ ''p'', or '''89''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 3, 4, 6, or 9. If 44 ◁ ''x'', then '''449''' ◁ ''p''. Hence we may assume ''x'' contains zero or one 4's. If x contains no 4's, then all digits of ''x'' are 0, 3, 6, or 9, and thus all digits of ''p'' are 0, 3, 6, or 9. But then, since the digits of ''p'' all have a common factor 3, ''p'' is divisible by 3, so ''p'' cannot be prime. Hence we may assume that ''x'' contains exactly one 4. Case 4.1: ''p'' begins with 3. In this case we can write ''p'' = 3''y''4''z''9, where all digits of ''y'', ''z'' are 0, 3, 6, or 9. We must have '''349''' ◁ ''p''. Case 4.2: ''p'' begins with 4. In this case we can write ''p'' = 4''y''9, where all digits of ''y'' are 0, 3, 6, or 9. If 0 ◁ ''y'', then '''409''' ◁ ''p''. If 3 ◁ ''y'', then 43 ◁ ''p''. If 9 ◁ ''y'', then '''499''' ◁ ''p''. Hence we may assume ''y'' ∈ {6}, and thus ''p'' ∈ 4{6}9. But then ''p'' is divisible by 7, since for ''n'' ≥ 0 we have 7 × 6<sub>''n''</sub>7 = 46<sub>''n''</sub>9. Case 4.3: ''p'' begins with 6. In this case we can write p = 6''y''4''z''9, where all digits of ''y'', ''z'' are 0, 3, 6, or 9. If 0 ◁ ''z'', then 409 ◁ ''p''. If 3 ◁ ''z'', then 43 ◁ ''p''. If 6 ◁ ''z'', then '''6469''' ◁ ''p''. If 9 ◁ ''z'', then 499 ◁ ''p''. Hence we may assume ''z'' is empty. If 3 ◁ ''y'', then 349 ◁ ''p''. If 9 ◁ ''y'', then '''6949''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 6. If 06 ◁ ''y'', then '''60649''' ◁ ''p''. Hence we may assume ''y'' ∈ {6}{0}. If 666 ◁ ''y'', then '''666649''' ◁ ''p''. If 00000 ◁ ''y'', then '''60000049''' ◁ ''p''. Hence we may assume ''y'' ∈ {''𝜆'', 0, 00, 000, 0000, 6, 60, 600, 6000, 60000, 66, 660, 6600, 66000, 660000}, and thus ''p'' ∈ {649, 6049, 60049, 600049, 6000049, 6649, 66049, 660049, 6600049, 66000049, 66649, 666049, 6660049, 66600049, 666000049}, and of these numbers only '''66000049''' and '''66600049''' are primes. Case 4.4: ''p'' begins with 9. In this case we can write p = 9''y''4''z''9, where all digits of ''y'', ''z'' are 0, 3, 6, or 9. If 0 ◁ ''y'', then '''9049''' ◁ ''p''. If 3 ◁ ''y'', then 349 ◁ ''p''. If 6 ◁ ''y'', then '''9649''' ◁ ''p''. If 9 ◁ ''y'', then '''9949''' ◁ ''p''. Hence we may assume ''y'' is empty. If 0 ◁ ''z'', then 409 ◁ ''p''. If 3 ◁ ''z'', then 43 ◁ ''p''. If 9 ◁ ''z'', then 499 ◁ ''p''. Hence we may assume ''z'' ∈ {6}, and thus ''p'' ∈ 94{6}9, and the smallest prime ''p'' ∈ 94{6}9 is 946669.

Athena problem is: Give a [[:w:Natural number|natural number]] ''b'' > 1, find the [[:w:Set (mathematics)|set]] of the [[:w:Minimal element|minimal element]]s of the set of the "[[:w:Prime number|prime number]] [[:w:Greater than|>]] ''b''" [[:w:Numerical digit|digit]] [[:w:String (computer science)|string]]s in the [[:w:Positional numeral system|positional numeral system]] with [[:w:Radix|base]] ''b'' for the [[:w:Subsequence|subsequence]] [[:w:Partially ordered set|ordering]]. (A string ''x'' is a subsequence of another string ''y'', if ''x'' can be obtained from ''y'' by deleting zero or more of the [[:w:Character (computing)|character]]s in ''y''. For example, 514 is a subsequence of 352148, "string" is a subsequence of "meistersinger". In contrast, 758 is not a subsequence of 378259, "abc" is not a subsequence of "cbacacba", since the characters must be in the same order) (Unlike [[:w:Substring|substring]], subsequence is not required to occupy consecutive positions within the original sequences, e.g. the [[:w:Longest common subsequence|longest common subsequence problem]] is different from the [[:w:Longest common substring|longest common substring problem]]) Using [[:w:Formal language theory|formal language theory]] terminology, Athena problem is finding the [[:w:Set (mathematics)|set]] of the [[:w:Minimal element|minimal element]]s of the [[:w:Formal language|language]] of base-''b'' [[:w:Representation (mathematics)|representation]]s of the [[:w:Prime number|prime number]]s [[:w:Greater than|>]] ''b'' (which is a set of [[:w:String (computer science)|string]]s of [[:w:Symbol|symbol]]s over the [[:w:Alphabet (formal languages)|alphabet]] ''Σ''<sub>''b''</sub> := {0, 1, ..., ''b''−1}), under the subsequence ordering (i.e. the [[:w:Binary relation|binary relation]] "is a subsequence of", which is a [[:w:Partially ordered set|partial ordering]]), for a given natural number ''b'' > 1. (You can draw this ordering as [[:w:Hasse diagram|Hasse diagram]] to find all [[:w:Minimal element|minimal element]]s) By [[:w:Higman's lemma|Higman's lemma]], there are no [[:w:Infinite set|infinite]] [[:w:Antichain|antichain]]s for the subsequence ordering (i.e. the subsequence ordering is always a [[:w:Well-quasi-ordering|well quasi order]]) (i.e. under the subsequence ordering (i.e. the [[:w:Binary relation|binary relation]] "is a subsequence of", which is a [[:w:Partially ordered set|partial ordering]]), every set of pairwise incomparable (i.e. not [[:w:Comparability|comparable]]) strings is finite), thus there must be only finitely many such minimal elements. In other words, the set of such minimal elements must be a [[:w:Finite set|finite set]], e.g. in [[:w:Decimal|decimal]] (base ''b'' = 10), this set has exactly 77 [[:w:Element of a set|element]]s: {11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 227, 251, 257, 277, 281, 349, 409, 449, 499, 521, 557, 577, 587, 727, 757, 787, 821, 827, 857, 877, 881, 887, 991, 2087, 2221, 5051, 5081, 5501, 5581, 5801, 5851, 6469, 6949, 8501, 9001, 9049, 9221, 9551, 9649, 9851, 9949, 20021, 20201, 50207, 60649, 80051, 666649, 946669, 5200007, 22000001, 60000049, 66000049, 66600049, 80555551, 555555555551, 5000000000000000000000000000027}.

For the unsolved bases ''b'' = 17, 19, 21, 23, 25, 26, 27, 28, 29, 31, 32, 34, 35, 36, Athena problem is solved (if probable primes are allowed) except 771 [[:w:Indexed family|families]] of the form ''x''{''y''}''z'' (where ''x'' and ''z'' are strings (may be [[:w:Empty string|empty]]) of digits in base ''b'', ''y'' is a digit in base ''b'') = sequence {''xz'', ''xyz'', ''xyyz'', ''xyyyz'', ''xyyyyz'', ''xyyyyyz'', ...} (i.e. "''xy''<sup>+</sup>''z''" in [[:w:Regular expression|regular expression]]), all of these 771 families contain no primes > ''b'' or probable primes > ''b'' with length ≤ 100000. == Results == These are the results of the Athena problem in bases 2 ≤ ''b'' ≤ 36 (we stop at base 36 since this base is the maximum base for which it is possible to write the numbers with the [[:w:Symbol|symbol]]s 0, 1, 2, ..., 9 and A, B, C, ..., Z (i.e. the 10 [[:w:Arabic numerals|Arabic numerals]] and the 26 [[:w:Latin script|Latin letters]]): (some large primes are only probable primes, i.e. not definitely primes, since they are too large to be [[:w:Elliptic curve primality|ECPP proved]] and [[:w:Pocklington primality test#Extensions and variants|neither ''N''−1 nor ''N''+1 can be ≥ 1/3 factored]], all of them pass the [[:w:Baillie–PSW primality test|Baillie–PSW primality test]] and the [[:w:Strong pseudoprime|strong primality test]] (i.e. the [[:w:Miller–Rabin primality test|Miller–Rabin primality test]]) with all prime bases ''p'' ≤ 61, however, all primes < 10<sup>25000</sup> for bases ''b'' = 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 18, 20, 22, 24, 26, 28, 30, 36 are definitely primes, most of them > 10<sup>299</sup> are proven primes with [[:w:Elliptic curve primality|ECPP proving]], others > 10<sup>299</sup> are proven primes with [[:w:Pocklington primality test#Extensions and variants|''N''−1 or ''N''+1 proving]]) To solve the Athena problem for a given base ''b'', we must [[:w:Computing|compute]] the element up to families of the form ''x''{''y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''y'' is a digit in base ''b'') (we call such families ''linear families''), and find the smallest prime > ''b'' in all such families.

If the methods we have discussed cannot be used to rule out or shrink ''x''{''Y''}''z'' where ''Y'' = {''y''<sub>1</sub>, ''y''<sub>2</sub>, ..., ''y''<sub>''n''</sub>}, then we can replace ''x''{''Y''}''z'' by ''xy''<sub>1</sub>{''Y''}''z'' ∪ ''xy''<sub>2</sub>{''Y''}''z'' ∪ ... ∪ ''xy''<sub>''n''</sub>{''Y''}''z'' and re-run the methods on this new [[:w:Formal language|language]]. If all remain families are linear families (i.e. of the form ''x''{''y''}''z'', where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''y'' is a digit in base ''b''), then we search the smallest (probable) primes in these families and add these primes to the list. e.g. in decimal (base ''b'' = 10): * The smallest prime in the family 5{0}27 is 5000000000000000000000000000027. * The smallest prime in the family {5}1 is 555555555551. * The smallest prime in the family 8{5}1 is 8555555555555555555551, but 8555555555555555555551 is not a minimal element since 555555555551 is a subsequence of 8555555555555555555551. There is no guarantee that the techniques discussed will ever terminate, but in practice they often do. They are able to determine the set of the minimal elements in base ''b'' for 2 ≤ ''b'' ≤ 16 and ''b'' = 18, 20, 22, 24, 30. The bases ''b'' = 17, 19, 21, 23, 25 ≤ ''b'' ≤ 29, 31 ≤ ''b'' ≤ 36 are solved with the exception of 771 families of the form ''x''{''y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''y'' is a digit in base ''b''). The following is a "[[:w:Semi-algorithm|semi-algorithm]]" that is guaranteed to solve the Athena problem for a given base ''b'', but it is not so easy to implement: # ''M'' = ''[[:w:Empty string|∅]]'' # while (''L'' ≠ ''∅'') do # choose ''x'', a shortest string in ''L'' # ''M'' := ''M'' ∪ {''x''} # ''L'' := ''L'' − ''sup''({''x''}) In practice, for arbitrary ''L'', we cannot feasibly carry out step 5. Instead, we work with ''L''&#39;, some regular overapproximation to ''L'', until we can show ''L''&#39; = ''∅'' (which implies ''L'' = ''∅''). In practice, ''L''&#39; is usually chosen to be a finite [[:w:Union (set theory)|union]] of sets of the form ''L''<sub>1</sub>{''L''<sub>2</sub>}''L''<sub>3</sub>, where each of ''L''<sub>1</sub>, ''L''<sub>2</sub>, ''L''<sub>3</sub> is finite. In the case we consider in this project, we then have to determine whether such a family contains a prime or not. Thus, Athena problem in bases ''b'' around 500 may be [[:w:NP-complete|NP-complete]] or [[:w:NP-hard|NP-hard]], or an [[:w:Undecidable problem|undecidable problem]], or an example of [[:w:Gödel's incompleteness theorems|Gödel's incompleteness theorems]] (like the [[:w:Continuum hypothesis|continuum hypothesis]] and the [[:w:Halting problem|halting problem]]). To solve the Athena problem, we need to determine whether a given family contains a prime. In practice, if family ''x''{''Y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''Y'' is a set of digits in base ''b'') could not be ruled out as only containing composites and ''Y'' contains two or more digits, then a relatively small prime > ''b'' could always be found in this family. Intuitively, this is because there are a large number of small strings in such a family, and at least one is likely to be prime (e.g. there are 2<sup>''n''−2</sup> strings of length ''n'' in the family 1{3,7}9, and there are over a thousand strings of length 12 in the family 1{3,7}9, thus it is very impossible that these numbers are all composite). In the case ''Y'' contains only one digit, this family is of the form ''x''{''y''}''z'', and there is only a single string of each length > (the length of ''x'' + the length of ''z''), and it is not known if the following [[:w:Decision problem|decision problem]] is recursively solvable (just like [[:w:Sierpiński number|Sierpiński problem]] and [[:w:Riesel number|Riesel problem]], Sierpiński problem and Riesel problem can be generalized to other bases ''b'', in fact, Athena problem in base ''b'' covers the Sierpiński problem in base ''b'' and the Riesel problem in base ''b'' with ''k'' < ''b'', i.e. finding the smallest prime of the form ''k''×''b''<sup>''n''</sup>+1 and ''k''×''b''<sup>''n''</sup>−1 (or prove such prime does not exist) with ''k'' < ''b'', since the smallest prime of the form ''k''×''b''<sup>''n''</sup>+1 and ''k''×''b''<sup>''n''</sup>−1 (if exists) must be a minimal element in base ''b''): Problem: Given strings ''x'', ''z'' (may be empty), a digit ''y'', and a base ''b'' (''x'' does not [[:w:Leading zero|start with the digit 0]], ''z'' ends with a digit which [[:w:Coprime integers|coprime]] to ''b'', ''y'' is not 0 if ''x'' is empty, ''y'' is coprime to ''b'' if ''z'' is empty), does there exist a prime number whose base-''b'' expansion is of the form ''xy''<sub>''n''</sub>''z'' for some ''n'' ≥ 0? Some families can be ruled out to contain no prime > ''b'' by [[:w:Covering set|covering congruence]], [[:w:Factorization of polynomials|algebraic factorization]] (e.g. [[:w:Difference of two squares|difference of two squares]], [[:w:Sum of two cubes|sum of two cubes]], [[:w:Sophie Germain's identity|Sophie Germain's identity of ''x''<sup>4</sup>+4×''y''<sup>4</sup>]]), or combine of them, e.g. * The base 9 family 2{7}: Always divisible by 2 or 5 * The base 16 family {8}F: Always divisible by 3, 7, or 13 * The base 21 family {7}D: Always divisible by 2, 13, or 17 * The base 23 family {D}GA: Always divisible by 2, 5, 7, 37, or 79 * The base 9 family 3{8}: Can be written as 4×9<sup>''n''</sup>−1 and can be factored as (2×3<sup>''n''</sup>−1) × (2×3<sup>''n''</sup>+1) * The base 8 family 1{0}1: Can be written as 8<sup>''n''</sup>+1 and can be factored as (2<sup>''n''</sup>+1) × (4<sup>''n''</sup>−2<sup>''n''</sup>+1) * The base 16 family {4}1: Can be written as (4×16<sup>''n''</sup>−49)/15 and can be factored as (2×3<sup>''n''</sup>−7) × (2×3<sup>''n''</sup>+7) / 15 * The base 16 family {C}D: Can be written as (4×16<sup>''n''</sup>+1)/5 and can be factored as (2×4<sup>''n''</sup>−2×2<sup>''n''</sup>+1) × (2×4<sup>''n''</sup>+2×2<sup>''n''</sup>+1) / 5 * The base 14 family 8{D}: Can be written as 9×14<sup>''n''</sup>−1, it is divisible by 5 if ''n'' is odd and can be factored as (3×14<sup>''n''/2</sup>−1) × (3×14<sup>''n''/2</sup>+1) if ''n'' is even * The base 12 family {B}9B: Can be written as 12<sup>''n''</sup>−25, it is divisible by 13 if ''n'' is odd and can be factored as (12<sup>''n''/2</sup>−5) × (12<sup>''n''/2</sup>+5) if ''n'' is even * The base 17 family 1{9}: Can be written as (25×17<sup>''n''</sup>−9)/16, it is divisible by 2 if ''n'' is odd and can be factored as (5×17<sup>''n''/2</sup>−3) × (5×17<sup>''n''/2</sup>+3) / 16 if ''n'' is even * The base 19 family 1{6}: Can be written as (4×19<sup>''n''</sup>−1)/3, it is divisible by 5 if ''n'' is odd and can be factored as (2×19<sup>''n''/2</sup>−1) × (2×19<sup>''n''/2</sup>+1) / 3 if ''n'' is even By the [[:w:Prime number theorem|prime number theorem]], the [[:w:Probability|chance]] that a [[:w:Random number|random]] ''n''-digit base ''b'' number is prime is [[:w:Asymptotic analysis|approximately]] 1/''n'' (more accurately, the chance is approximately 1/(''n''×''ln''(''b'')), where ''ln'' is the [[:w:Natural logarithm|natural logarithm]]). If one conjectures the numbers ''x''{''y''}''z'' behave similarly (i.e. the numbers ''x''{''y''}''z'' is a [[:w:Pseudorandomness|pseudorandom sequence]]) you would expect [[:w:Harmonic_series (mathematics)|1/1 + 1/2 + 1/3 + 1/4 + ... = ∞]] primes of the form ''x''{''y''}''z'' (of course, this does not always happen, since some ''x''{''y''}''z'' families can be ruled out to contain no prime > ''b'' (by covering congruence, algebraic factorization, or combine of them), but it is at least a reasonable conjecture in the absence of evidence to the contrary. Hence, the [[:w:Heuristic argument|heuristic argument]] suggests there are always infinitely many primes in family ''x''{''y''}''z'' (where ''x'' and ''z'' are strings (may be empty) of digits in base ''b'', ''y'' is a digit in base ''b'') if it cannot be ruled out to contain no prime or only contain finitely many primes, by covering congruence, algebraic factorization, or combine of them.

problem in decimal (base ''b'' = 10) == '''Bold''' for the minimal elements, ''x'' ◁ ''y'' means ''x'' is a subsequence of ''y''. Assume ''p'' is a prime > 10, and the last digit of ''p'' must lie in {1,3,7,9}. Case 1: ''p'' ends with 1. In this case we can write ''p'' = ''x''1. If ''x'' contains 1, 3, 4, 6, or 7, then (respectively) '''11''' ◁ ''p'', '''31''' ◁ ''p'', '''41''' ◁ ''p'', '''61''' ◁ ''p'', or '''71''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 2, 5, 8, or 9. Case 1.1: ''p'' begins with 2. In this case we can write ''p'' = 2''y''1. If 5 ◁ ''y'', then '''251''' ◁ ''p''. If 8 ◁ ''y'', then '''281''' ◁ ''p''. If 9 ◁ ''y'', then 29 ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 2. If 22 ◁ ''y'', then '''2221''' ◁ ''p''. Hence we may assume ''y'' contains zero or one 2's. If ''y'' contains no 2's, then ''p'' ∈ 2{0}1. But then, since the sum of the digits of ''p'' is 3, ''p'' is divisible by 3, so ''p'' cannot be prime. If ''y'' contains exactly one 2, then we can write ''p'' = 2''z''2''w''1, where ''z'',''w'' ∈ {0}. If 0 ◁ ''z'' and 0 ◁ ''w'', then '''20201''' ◁ ''p''. Hence we may assume either ''z'' or ''w'' is empty. If ''z'' is empty, then ''p'' ∈ 22{0}1, and the smallest prime ''p'' ∈ 22{0}1 is '''22000001'''. If ''w'' is empty, then ''p'' ∈ 2{0}21, and the smallest prime ''p'' ∈ 2{0}21 is '''20021'''. Case 1.2: ''p'' begins with 5. In this case we can write ''p'' = 5''y''1. If 2 ◁ ''y'', then '''521''' ◁ ''p''. If 9 ◁ ''y'', then 59 ◁ ''p''. Hence we may assume all digits of ''y'' are 0, 5, or 8. If 05 ◁ ''y'', then '''5051''' ◁ ''p''. If 08 ◁ ''y'', then '''5081''' ◁ ''p''. If 50 ◁ ''y'', then '''5501''' ◁ ''p''. If 58 ◁ ''y'', then '''5581''' ◁ ''p''. If 80 ◁ ''y'', then '''5801''' ◁ ''p''. If 85 ◁ ''y'', then '''5851''' ◁ ''p''. Hence we may assume ''y'' ∈ {0} ∪ {5} ∪ {8}. If ''y'' ∈ {0}, then ''p'' ∈ 5{0}1. But then, since the sum of the digits of ''p'' is 6, ''p'' is divisible by 3, so ''p'' cannot be prime. If ''y'' ∈ {5}, then ''p'' ∈ 5{5}1, and the smallest prime ''p'' ∈ 5{5}1 is '''555555555551'''. If ''y'' ∈ {8}, since if 88 ◁ ''y'', then 881 ◁ ''p'', hence we may assume ''y'' ∈ {''𝜆'',8}, and thus ''p'' ∈ {51,581}, but 51 and 581 are both composite. Case 1.3: ''p'' begins with 8. In this case we can write p = 8''y''1. If 2 ◁ ''y'', then '''821''' ◁ ''p''. If 8 ◁ ''y'', then '''881''' ◁ ''p''. If 9 ◁ ''y'', then 89 ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 5. If 50 ◁ ''y'', then '''8501''' ◁ ''p''. Hence we may assume y ∈ {0}{5}. If 005 ◁ ''y'', then '''80051''' ◁ p. Hence we may assume y ∈ {0} ∪ {5} ∪ 0{5}. If y ∈ {0}, then ''p'' ∈ 8{0}1. But then, since the sum of the digits of ''p'' is 9, ''p'' is divisible by 3, so ''p'' cannot be prime. If y ∈ {5}, since if 55555555555 ◁ ''y'', then 555555555551 ◁ ''p'', hence we may assume ''y'' ∈ {''𝜆'', 5, 55, 555, 5555, 55555, 555555, 5555555, 55555555, 555555555, 5555555555}, and thus ''p'' ∈ {81, 851, 8551, 85551, 855551, 8555551, 85555551, 855555551, 8555555551, 85555555551, 855555555551}, but all of these numbers are composite. If y ∈ 0{5}, since if 55555555555 ◁ ''y'', then 555555555551 ◁ ''p'', hence we may assume ''y'' ∈ {0, 05, 055, 0555, 05555, 055555, 0555555, 05555555, 055555555, 0555555555, 05555555555}, and thus ''p'' ∈ {801, 8051, 80551, 805551, 8055551, 80555551, 805555551, 8055555551, 80555555551, 805555555551, 8055555555551}, and of these numbers only 80555551 and 8055555551 are primes, but 80555551 ◁ 8055555551, thus only '''80555551''' is a minimal element. Case 1.4: ''p'' begins with 9. In this case we can write p = 9''y''1. If 9 ◁ ''y'', then '''991''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0, 2, 5, or 8. If 00 ◁ ''y'', then '''9001''' ◁ ''p''. If 22 ◁ ''y'', then '''9221''' ◁ ''p''. If 55 ◁ ''y'', then '''9551''' ◁ ''p''. If 88 ◁ ''y'', then 881 ◁ ''p''. Hence we may assume ''y'' contains at most one 0, at most one 2, at most one 5, and at most one 8. If ''y'' only contains at most one 0 and does not contain any of {2,5,8}, then ''y'' ∈ {''𝜆'',0}, and thus ''p'' ∈ {91,901}, but 91 and 901 are both composite. If ''y'' only contains at most one 0 and only one of {2,5,8}, then the sum of the digits of ''p'' is divisible by 3, ''p'' is divisible by 3, so ''p'' cannot be prime. Hence we may assume ''y'' contains at least two of {2,5,8}. If 25 ◁ ''y'', then 251 ◁ ''p''. If 28 ◁ ''y'', then 281 ◁ ''p''. If 52 ◁ ''y'', then 521 ◁ ''p''. If 82 ◁ ''y'', then 821 ◁ ''p''. Hence we may assume ''y'' contains no 2's (since if ''y'' contains 2, then ''y'' cannot contain either 5's or 8's, which is a contradiction). If 85 ◁ ''y'', then '''9851''' ◁ ''p''. Hence we may assume ''y'' ∈ {58,580,508,058}, and thus ''p'' ∈ {9581,95801,95081,90581}, and of these numbers only 95801 is prime, but 95801 is not a minimal element since 5801 ◁ 95801. Case 2: ''p'' ends with 3. In this case we can write p = ''x''3. If ''x'' contains 1, 2, 4, 5, 7, or 8, then (respectively) '''13''' ◁ ''p'', '''23''' ◁ ''p'', '''43''' ◁ ''p'', '''53''' ◁ ''p'', '''73''' ◁ ''p'', or '''83''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 3, 6, or 9, and thus all digits of ''p'' are 0, 3, 6, or 9. But then, since the digits of ''p'' all have a common factor 3, ''p'' is divisible by 3, so ''p'' cannot be prime. Case 3: ''p'' ends with 7. In this case we can write ''p'' = ''x''7. If ''x'' contains 1, 3, 4, 6, or 9, then (respectively) '''17''' ◁ ''p'', '''37''' ◁ ''p'', '''47''' ◁ ''p'', '''67''' ◁ ''p'', or '''97''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 2, 5, 7, or 8. Case 3.1: ''p'' begins with 2. In this case we can write ''p'' = 2''y''7. If 2 ◁ ''y'', then '''227''' ◁ ''p''. If 5 ◁ ''y'', then '''257''' ◁ ''p''. If 7 ◁ ''y'', then '''277''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 8. If 08 ◁ ''y'', then '''2087''' ◁ ''p''. If 88 ◁ ''y'', then 887 ◁ ''p''. Hence we may assume ''y'' ∈ {0} ∪ 8{0}. If ''y'' ∈ {0}, then ''p'' ∈ 2{0}7. But then, since the sum of the digits of ''p'' is 9, ''p'' is divisible by 3, so ''p'' cannot be prime. If y ∈ 8{0}, then ''p'' ∈ 28{0}7. But then ''p'' is divisible by 7, since for ''n'' ≥ 0 we have 7 × 40<sub>''n''</sub>1 = 280<sub>''n''</sub>7. Case 3.2: ''p'' begins with 5. In this case we can write ''p'' = 5''y''7. If 5 ◁ ''y'', then '''557''' ◁ ''p''. If 7 ◁ ''y'', then '''577''' ◁ ''p''. If 8 ◁ ''y'', then '''587''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 2. If 22 ◁ ''y'', then 227 ◁ ''p''. Hence we may assume ''y'' contains zero or one 2's. If ''y'' contains no 2's, then ''p'' ∈ 5{0}7. But then, since the sum of the digits of ''p'' is 12, ''p'' is divisible by 3, so ''p'' cannot be prime. If ''y'' contains exactly one 2, then we can write ''p'' = 5''z''2''w''7, where ''z'',''w'' ∈ {0}. If 0 ◁ ''z'' and 0 ◁ ''w'', then '''50207''' ◁ ''p''. Hence we may assume either ''z'' or ''w'' is empty. If ''z'' is empty, then ''p'' ∈ 52{0}7, and the smallest prime ''p'' ∈ 52{0}7 is '''5200007'''. If ''w'' is empty, then ''p'' ∈ 5{0}27, and the smallest prime ''p'' ∈ 5{0}27 is '''5000000000000000000000000000027'''. Case 3.3: ''p'' begins with 7. In this case we can write ''p'' = 7''y''7. If 2 ◁ ''y'', then '''727''' ◁ ''p''. If 5 ◁ ''y'', then '''757''' ◁ ''p''. If 8 ◁ ''y'', then '''787''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 7, and thus all digits of ''p'' are 0 or 7. But then, since the digits of ''p'' all have a common factor 7, ''p'' is divisible by 7, so ''p'' cannot be prime. Case 3.4: ''p'' begins with 8. In this case we can write ''p'' = 8''y''7. If 2 ◁ ''y'', then '''827''' ◁ ''p''. If 5 ◁ ''y'', then '''857''' ◁ ''p''. If 7 ◁ ''y'', then '''877''' ◁ ''p''. If 8 ◁ ''y'', then '''887''' ◁ ''p''. Hence we may assume ''y'' ∈ {0}, and thus ''p'' ∈ 8{0}7. But then, since the sum of the digits of ''p'' is 15, ''p'' is divisible by 3, so ''p'' cannot be prime. Case 4: ''p'' ends with 9. In this case we can write ''p'' = ''x''9. If ''x'' contains 1, 2, 5, 7, or 8, then (respectively) '''19''' ◁ ''p'', '''29''' ◁ ''p'', '''59''' ◁ ''p'', '''79''' ◁ ''p'', or '''89''' ◁ ''p''. Hence we may assume all digits of ''x'' are 0, 3, 4, 6, or 9. If 44 ◁ ''x'', then '''449''' ◁ ''p''. Hence we may assume ''x'' contains zero or one 4's. If x contains no 4's, then all digits of ''x'' are 0, 3, 6, or 9, and thus all digits of ''p'' are 0, 3, 6, or 9. But then, since the digits of ''p'' all have a common factor 3, ''p'' is divisible by 3, so ''p'' cannot be prime. Hence we may assume that ''x'' contains exactly one 4. Case 4.1: ''p'' begins with 3. In this case we can write ''p'' = 3''y''4''z''9, where all digits of ''y'', ''z'' are 0, 3, 6, or 9. We must have '''349''' ◁ ''p''. Case 4.2: ''p'' begins with 4. In this case we can write ''p'' = 4''y''9, where all digits of ''y'' are 0, 3, 6, or 9. If 0 ◁ ''y'', then '''409''' ◁ ''p''. If 3 ◁ ''y'', then 43 ◁ ''p''. If 9 ◁ ''y'', then '''499''' ◁ ''p''. Hence we may assume ''y'' ∈ {6}, and thus ''p'' ∈ 4{6}9. But then ''p'' is divisible by 7, since for ''n'' ≥ 0 we have 7 × 6<sub>''n''</sub>7 = 46<sub>''n''</sub>9. Case 4.3: ''p'' begins with 6. In this case we can write p = 6''y''4''z''9, where all digits of ''y'', ''z'' are 0, 3, 6, or 9. If 0 ◁ ''z'', then 409 ◁ ''p''. If 3 ◁ ''z'', then 43 ◁ ''p''. If 6 ◁ ''z'', then '''6469''' ◁ ''p''. If 9 ◁ ''z'', then 499 ◁ ''p''. Hence we may assume ''z'' is empty. If 3 ◁ ''y'', then 349 ◁ ''p''. If 9 ◁ ''y'', then '''6949''' ◁ ''p''. Hence we may assume all digits of ''y'' are 0 or 6. If 06 ◁ ''y'', then '''60649''' ◁ ''p''. Hence we may assume ''y'' ∈ {6}{0}. If 666 ◁ ''y'', then '''666649''' ◁ ''p''. If 00000 ◁ ''y'', then '''60000049''' ◁ ''p''. Hence we may assume ''y'' ∈ {''𝜆'', 0, 00, 000, 0000, 6, 60, 600, 6000, 60000, 66, 660, 6600, 66000, 660000}, and thus ''p'' ∈ {649, 6049, 60049, 600049, 6000049, 6649, 66049, 660049, 6600049, 66000049, 66649, 666049, 6660049, 66600049, 666000049}, and of these numbers only '''66000049''' and '''66600049''' are primes. Case 4.4: ''p'' begins with 9. In this case we can write p = 9''y''4''z''9, where all digits of ''y'', ''z'' are 0, 3, 6, or 9. If 0 ◁ ''y'', then '''9049''' ◁ ''p''. If 3 ◁ ''y'', then 349 ◁ ''p''. If 6 ◁ ''y'', then '''9649''' ◁ ''p''. If 9 ◁ ''y'', then '''9949''' ◁ ''p''. Hence we may assume ''y'' is empty. If 0 ◁ ''z'', then 409 ◁ ''p''. If 3 ◁ ''z'', then 43 ◁ ''p''. If 9 ◁ ''z'', then 499 ◁ ''p''. Hence we may assume ''z'' ∈ {6}, and thus ''p'' ∈ 94{6}9, and the smallest prime ''p'' ∈ 94{6}9 is 946669.

Except in times of terror, massive lawlessness or war, most humans place a high priority on their financial situation, the primary focus of Part I.

However, there is a growing body of research documenting :(a) how most uses of violence are counterproductive, and :(b) that there are usually nonviolent options to violence that would more effectively promote broadly shared peace and prosperity for the long term. This research is rarely discussed by major media outlets, because it would offend the "people"<ref>We put "people" in quotes in this essay, because that term includes corporations under current US law.</ref> who control most of the money for the media: Nonviolence threatens their ability to get compliance from security forces. As a result, many elites prefer to use force to the detriment of the bottom 99 percent of humanity. As discussed below, a military posture that supports projecting force beyond one’s own borders may be as likely to ''provoke'' as ''prevent'' an attack.<ref>For example, Lebow (2025) cites some of his previous work with others to support the claim that large militaries have been "more provocative than preventative in" their effects. And Lebow (2024) insists that, "Policymakers respond more instinctively than analytically in deciding that some policy is or is not in the national interest." See also Lebow et al. (2023).</ref> This chapter outlines a 3-part strategy that research suggests would more likely lead to better outcomes for the vast majority of humans: # Citizen-directed subsidies for local news nonprofits with a firewall to prevent political interference in the content. # Training in nonviolent noncooperation for anyone willing to listen. # Forbid uses of force beyond one’s own borders and covert interference in foreign countries.

Quoted from the ''[[w:National Gazette|National Gazette]]'' (published 1791-1793) by Schmeller (2009, p. 36) and Sauer (2016, p. 5). Sauer described how the American Revolutionaries, especially the first four US presidents, planted stories in newspapers to build support for how they dealt with the [[w:Barbary corsairs|Barbary pirates]], who were seizing merchant ships, raiding European coastal towns and villages, and selling European captives into slavery. The first two US presidents, [[w:George Washington|Washington]] and [[w:John Adams|Adams]], used that support for protecting US shipping and citizens by paying tribute to government leaders in Morocco, Algeria, Tunisia, and Libya.

Eisenhower|Eisenhower]] wrote in his autobiography, which appeared in 1963 (he left the presidency 1961-01-20), that he had never communicated {{quote| with a person knowledgeable in Indochinese affairs [including Vietnam] who did not agree that had elections been held as of the time of the fighting [leading to the defeat of the French in 1954], possibly 80 per cent of the population would have voted for the Communist [[w:Ho Chi Minh|Ho Chi Minh]].<ref>Eisenhower (1963, p. 372).</ref>}} [[w:Joseph McCarthy|Joseph McCarthy]], who had been elected to the US Senate in 1946 and "experienced a meteoric rise in national profile beginning on February 9, 1950, when he gave a" speech during which he said something like, "The [[w:United States Secretary of State|State Department]] is infested with communists. I have here in my hand a list of 205—a list of names that were made known to the Secretary of State as being members of the Communist Party and who nevertheless are still working and shaping policy in the State Department." McCarthy's mostly baseless claims went largely unchallenged in the media, including accusing the Democrats of "twenty years of treason" for having been allied with the Soviet Union, which took the bulk of casualties during World War II. By the end of 1953 with (Republican) Eisenhower as president roughly 11 months, McCarthy was complaining about "''21'' years of treason", complaining that Eisenhower was not sufficiently aggressive in rooting out the communists who McCarthy claimed were in the government.<ref>Fried (1997, p. 179).</ref> Then the French were defeated by Vietnamese communists 1954-05-07 in the [[w:Battle of Dien Bien Phu|Battle of Dien Bien Phu]]. The [[w:1954 Geneva Conference|1954 Geneva Conference]], which had begun eleven days earlier, 1954-04-26, concluded 1954-07-21 with the "Geneva Accords of 1954".<ref>The [[w:Battle of Dien Bien Phu|Battle of Dien Bien Phu]], 1954-05-07, effectively ended the [[w:First Indochina War|French Indochina War]]. This led to the [[w:1954 Geneva Conference|Geneva accords of 1954]], officially dated 1954-07-20 but actually signed the following morning. Those accords took effect on three different dates, July 27 and August 1 and 11 in three different sectors of Vietnam. See <!--Agreement on the Cessation of Hostilities in Vietnam-->{{cite Q|Q139676410}}</ref> Those accords called for UN-supervised elections for July of 1956, when Eisenhower would presumably be campaigning for reelection. Eisenhower doubtless knew that he might lose his bid for re-election in 1956, if the Communist Ho Chi Minh won elections in July of that year. :''The consistent suppression of honest portrayal in the major media of that day of the perspective of anyone whom Eisenhower considered "knowledgeable in Indochinese affairs" gave him -- and his successors [[w:John F. Kennedy|Kennedy]], [[w:Lyndon B. Johnson|Johnson]], and [[w:Richard Nixon|Nixon]] -- the choice between betraying the nation or not getting elected.'' In this environment, the [[w:Operation 34A|US initiated a series of clandestine operations against North Vietnam]] including infiltrating CIA-recruited spies and supporting attacks against North Vietnam by South Vietnamese commandos.<ref>Paterson (2008).</ref> This included a raid 1964-07-30 by South Vietnamese commandos on the island of Hòn Mê, roughly 300 km (180 miles) north of the [[w:Vietnamese Demilitarized Zone|Vietnamese Demilitarized Zone]] in the [[w:Gulf of Tonkin|Gulf of Tonkin]], covered by [[w:DESOTO patrol|US naval vessels]] patrolling in that area. Then during a dark and stormy night six days later, US naval vessels opened fire on radar snow, and President Johnson requested and received Congressional approval of the [[w:Gulf of Tonkin Resolution|Gulf of Tonkin Resolution]]; then-[[w:United States Secretary of Defense|US Secretary of Defense]] [[w:Robert McNamara|McNamara]] claimed those attacks were "unprovoked".<ref>Karnow (1983, p. 375). See also the section on [[w:Gulf of Tonkin Resolution#Congress votes|Congress votes]]" in the Wikipedia article on [[w:Gulf of Tonkin Resolution|Gulf of Tonkin Resolution]], accessed 2026-05-14.</ref> In this media environment, only two officials in the US Congress voted against the Gulf of Tonkin Resolution: [[w:Ernest Gruening|Ernest Gruening]] (D-AK) and [[w:Wayne Morse|Wayne Morse]] (D-OR). Gruening lost in his next primary campaign to [[w:Mike Gravel|Mike Gravel]], and Morse lost in his next general election campaign to [[w:Bob Packwood|Bob Packwood]]. These results support the previous claim that the major media give politicians the choice: :''Betray the nation, or do not get elected.'' That resolution became the primary authorization for the US war in Vietnam until Congress ended the funding. ==== Was the Vietnam War lost in Washington or by media biases? ==== [[w:John Mueller|John Mueller]], prolific author, Professor Emeritus of international relations at [[w:Ohio State University|Ohio State University]] and Senior Fellow at the [[w:Cato Institute|Cato Institute]], said that the most effective thing the US did to win the [[w:Cold War|Cold War]] was — :''nothing'': Between the [[w:Fall of Saigon|Fall of Saigon]] in 1975 and the inauguration of [[w:Ronald Reagan|Ronald Reagan]] as President of the US, the US "went into a sort of containment funk: it effectively adopted a policy of complacency (or perhaps of appeasement) as it watched from the sidelines as the Soviet Union … opportunistically gathered a set of Third World countries into its imperial embrace: Angola in 1976, Mozambique and Ethiopia in 1977, South Yemen and Afghanistan in 1978, Grenada and Nicaragua in 1979."<ref>Mueller (2021, p. 59).</ref> Nearly all became major economic and political drains on the Soviets with Afghanistan being the worst. And their Warsaw Pact allies in Eastern Europe became a severe economic drain and psychic problem.<ref>Mueller and Graves (2023).</ref> President Reagan, inaugurated 1981-01-20, had a very different vision of the role of the US in foreign relations from his predecessor, [[w:Jimmy Carter|Jimmy Carter]]. In 1983-06-21 Reagan insisted, "We cannot permit the Soviet-Cuban-Nicaraguan axis to take over Central America", because the consequences would include "a tidal wave of refugees ... 'feet people' ... swarming into our country."<ref>Clines (1983).</ref> Other sources<ref>e.g., Andersen (2006, Part II).</ref> insist the opposite, that the vast majority of deaths in Central America during the Reagan years were poor humans petitioning nonviolently for a redress of grievances, suppressed by terrorist / death squads supported by the Reagan administration largely in violation of laws passed by Congress and signed by President Reagan. On 1986-10-05 [[w:Corporate Air Services HPF821|a Nicaraguan soldier with a surface to air missile shot down a C-123]] cargo aircraft carrying supplies to the Contra roughly 35 miles (56 km) north of Costa Rica. Documents found in the wreckage and a confession by the sole survivor led to the [[w:Iran–Contra affair|Iran-Contra hearings]] the following year, during which Lt. Col. [[w:Oliver North|Oliver North]] insisted, "We didn't lose the war in Vietnam ..., we lost it in this city."<ref>Andersen (2006, p. 137). See also, Wikipedia, "[[w:Stab-in-the-back myth|Stab-in-the-back myth]]", accessed 2026-05-13.</ref> The previous section on the "Gulf of Tonkin Resolution" provides an alternative narrative of the Vietnam War: If as Eisenhower claimed, "possibly 80 per cent of the [Vietnamese] population would have voted for the Communist [[w:Ho Chi Minh|Ho Chi Minh]]" if elections had been held there, it's hard to imagine how anyone else could have won without aggressive action that actually ''improved'' the lives of Vietnamese peasants in the South. US-led efforts there were officially designed to win "[[w:Hearts and Minds (Vietnam War)|Hearts and Minds]]" but were implemented with such coercion that the result was the opposite. A cynic might say that it is hard to win people's hearts and minds by killing them. ====Richard Barlow and nuclear proliferation==== There is also documentation that the US helped Pakistan get nuclear weapons and destroyed the career of an intelligence analyst, [[w:Richard Barlow (intelligence analyst)|Richard Barlow]], for telling his managers they should not lie to Congress about it. Barlow has insisted that neither Pakistan nor North Korea would have nuclear weapons and Iran would not have a nuclear weapons program today, if the US had followed its own laws. Barlow’s claims, including his punishment by administration officials, have been reported in major media outlets<ref>e.g., Stein (2013). See also Wikipedia, "[[w:Richard Barlow (intelligence analyst)|Richard Barlow (intelligence analyst)]]", accessed 2026-05-06.</ref> but not in a way that would seriously limit the ability — and need — for administration officials to lie to Congress. ==== Nayirah testimony and the 1990-1991 Gulf War ==== A more recent example is the 1990-10-10 testimony by [[w:Nayirah testimony|Nayirah al-Ṣabaḥ to the US Congressional Human Rights Caucus]], two months after the Iraqi invasion of Kuwait. She claimed to have seen Iraqi soldiers taking premature babies out of incubators in a maternity ward before looting the incubators and leaving the babies to die on the floor after the Iraqi invasion of Kuweit; she said she had been a volunteer nurse in the hospital at that time. Her statements were widely publicized and cited numerous times in the United States Senate and by American president George H. W. Bush to contribute to the rationale for pursuing military action against Iraq. It was later revealed that she was the daughter of Kuwaiti ambassador Saud Nasser al-Saud al-Sabah and that her testimony was false.<ref>Andersen (2006, ch. 12).</ref> ==== 1998 Embassy bombings and September 11 ==== As another example, there is substantial documentation available today that [[1998 Embassy bombings and September 11|the suicide mass murders of September 11, 2001]], likely would not have occurred if the US had treated the 1998 bombings of the US embassies in Kenya and Tanzania as law enforcement issues. Muslim clerics all over the world initially condemned those acts. Al-Qaeda was dead. Their funding had largely dried up. And bin Laden was scheduled to be extradited the following month to Saudi Arabia to be prosecuted for treason, where he would likely have been convicted and executed.<ref>Those 1998 attacks on US embassies in Kenya and Tanzania were reportedly motivated as retaliation for US support for torture, transferring a colleague of bin Laden to Egypt for torture, according to Mayer (2008, p. 114). The major media in the US has provided ample coverage of, e.g., promises by Donald Trump supporting torture (McCarthy 2016), while largely suppressing honest discussion of the research on it. For example, around 1629 the Duke of Brunswick was discussing torture with two leading Jesuit scholars, who supported it. They insisted that torture had been used only with individuals identified by other "witches", who had "confessed" after torture. The Duke then led the Jesuits to a woman being stretched on the rack and asked her, “You are a confessed witch. I suspect these two men of being warlocks. What do you say? Another turn of the rack, executioners.” “No, no!” screamed the woman. “You are quite right. I have often seen .. . They can turn themselves into goats, wolves, and other animals. … Several witches have had children by them. … The children had heads like toads and legs like spiders.” The Duke then asked the Jesuits. “Shall I put you to the torture until you confess, my friends?” One of the Jesuits was [[w:Friedrich Spee|Friedrich Spee]], who thanked God he had been led to this insight by a friend and then wrote a book against torture. See Pinker (2011, pp. 138-139). Similar comments about the counterproductive nature of torture were made by General Stanley McChrystal (2013), who held several command positions in Iraq and Afghanistan.</ref> But it seemed questionable at best whether major media executives in the US would have given favorable coverage to such a diplomatic solution. Instead, the US bombed a pharmaceutical plant in Sudan and al-Qaeda training camps in Afghanistan. Then Muslim public opinion turned 180 degrees to conclude, "Bin Laden is right: The US ''is'' an evil empire." The US became bin Laden’s only indispensable ally, according to the CIA agent responsible for tracking bin Laden at that time.<ref>Scheuer (2004, p. xv).</ref> Leading Saudis started supporting al-Qaeda, including some working for the Saudi embassy and consulates in the US. Only one country seems to have been involved in the preparations for the September 11 attacks, and that was Saudi Arabia. But Saudis were friends of the Bush family, and a crisis is a terrible thing to waste.<ref>Romer (2009).</ref> :''Did the US invade Afghanistan and Iraq on grounds that senior journalists and leading media executives should have known at the time were questionable and likely fraudulent — to the detriment of nearly everyone except the "people" who control most of the money for the media?'' Similarly, on 2003-05-29 [[w:BBC|BBC]] journalist [[w:Andrew Gilligan|Andrew Gilligan]] reported that the [[w:Tony Blaire|Blair government]] had "sexed up" [[w:September Dossier|intelligence reports]] issued the previous September to justify supporting the 2003-03-20 [[w:Iraq War|US-led invasion of Iraq]], two months before Gilligan's report. This led to the [[w:Hutton Inquiry|Hutton Inquiry]], which led to the resignations of Gilligan and the BBC's chairman and the firing of the BBC's director-general. However, the British public expressed so many reservations about the Hutton Inquiry that a follow-up investigation was ordered in 2009. This became the "[[w:Iraq Inquiry|Iraq Inquiry]]", whose 2016-07-06 report essentially validated what Gilligan had said just over 13 years earlier. This provides one more example of the 1710 maxim of Jonathan Swift that, "Falsehood flies, and truth comes limping after ... like a physician, who hath found out an infallible medicine, after the patient is dead."<ref name=Swift/> ====Ukraine war==== Page 1 of the 2023-05-04 edition of ''[[w:Le Monde Diplomatique|Le Monde Diplomatique]] carried a headline: :One year after the invasion of Ukraine: The media, vanguard of the war party,<ref>Halimi and Rimbert (2023) in the French-language original.</ref> consistent with Andersen (2006). === in sum === You, dear reader, can help overcome these problems by talking, as suggested in the exercises below and the rest of this book. If you can help others become less angry and more willing to agree to disagree agreeably with others, that should reduce the risk of war and improve the prospects for progress on all the other major problems facing humanity today. ==2. Training in nonviolent noncooperation for anyone willing to listen == A major driver of the current conflict between India and Pakistan is mistreatment of Muslims in India. Simulations of a nuclear war between India and Pakistan suggest that such a war would likely produce a nuclear autumn lasting years during which 40 percent of humanity would starve to death if they did not die of something else sooner. Over 90 percent of those would be in countries not involved in the nuclear exchange.<ref>Xia et al. (2022). See also Wikiversity, "[[Responding to a nuclear attack]]", accessed 2026-05-05.</ref> The recent "[[w:2025 India–Pakistan conflict|2025 India–Pakistan conflict]]" was a response by India to violence in Indian-administered [[w:Kashmir|Kashmir]] by terrorists allegedly supported by Pakistan. India would have had much more difficulty justifying violent repression of ''nonviolent'' protests, especially if a more diverse media ecology gave such protests more and more sympathetic coverage. During the [[w:Great Depression|Great Depression]], ethnic Germans in the [[w:Sudetenland|Sudetenland]] region of [[w:Czechoslovakia|Czechoslovakia]] were harder hit by increasing trade barriers than their non-German neighbors. They were therefore more open to populist and extremist movements such as fascism, communism and German irredentism.<ref>Wikipedia, "[[w:Sudetenland|Sudetenland]]", esp. the section on "[[w: Sudetenland#Within the Czechoslovak Republic (1918–1938)|Within the Czechoslovak Republic (1918–1938)]]", accessed 2026-05-05.</ref> If those ethnic Germans had used nonviolent noncooperation to highlight their grievances, and if Czechoslovakia at that time had had a substantially more diverse media system, it seems likely that they could have gotten reasonable redress of grievances. If so, it would have been harder for Hitler to use that as an excuse to invade Czechoslovakia, as he did in 1938.<ref>Wikipedia, "[[w:Occupation of Czechoslovakia (1938–1945)|Occupation of Czechoslovakia (1938–1945)]]", accessed 2026-05-05.</ref> An ideal settlement of the current Russo-Ukraine war might include training in nonviolent noncooperation made more effective through a more diverse media culture as suggested above. A substantial portion of the Ukrainian population, especially the Ukrainian military, are reported to be vicious anti-Russian Nazis, and the Ukrainian government has outlawed many uses of non-Ukrainian languages, especially Russian.<ref>Horton (2024).</ref> A campaign of nonviolent noncooperation with a vigorous, diverse adversarial press would likely make it harder for Ukraine to continue any persecution of Russian speakers. It would also make it harder for major media in the US and Western Europe to suppress honest discussion of anti-Russian racism in Ukraine. Swanson (2022) said that the [[w:Baltic states|Baltic states]] have implemented such training in preparations for a possible Russian invasion; they might be asked to support such training in Ukraine (and elsewhere).<ref>Swanson (2022).</ref> === Life in prison for teaching nonviolence === Per the US Supreme Court decision in ''[[w:Holder v. Humanitarian Law Project|Holder v. Humanitarian Law Project]]'' (2010), teaching nonviolence to anyone whom the US State Department claims supports a foreign terrorist organization is "[[w:Providing material support for terrorism|providing material support for terrorism]]", which is a felony under the USA [[w:Patriot Act|Patriot Act]] of 2001. Moreover, if the State Department claims that the death of any "person" resulted from the activities of the designated foreign terrorist organization, the penalty can be life in prison, where "person" is defined in the Patriot Act as "any individual or entity capable of holding a legal or beneficial interest in property".<ref>The treatment of [[w:Sami Al-Arian|Sami Al-Arian]] is worth noting in discussing the Patriot Act. Al-Arian is a Kuwaiti-born political activist of Palestinian origin, who earned a doctorate in Electrical Sciences and Systems Engineering at [[w:North Carolina State University|North Carolina State]] in 1985 and taught computer engineering at [[w:University of South Florida|University of South Florida]] (USF) beginning in 1986. He was granted permanent resident status in 1989. In 1993 he earned a Distinguished Teacher Award as a tenured associate professor at USF. He was an [[w:imam|imam]] in a local [[w:mosque|mosque]] and led in other initiatives to promote dialogue and public policy initiatives between the West and Middle East. On September 26, 2001, he appeared on ''[[w:The O'Reilly Factor|The O'Reilly Factor]]'' where he was confronted with a 1988 recording of him shouting "death to Israel". Al-Arian replied that "Death to Israel" meant "death to occupation, ... apartheid, ...oppression," whereupon O'Reilly cut him off and called for the [[w:Central Intelligence Agency|Central Intelligence Agency]] to investigate him. Al-Arian spent most of the next 14 years between that 2001 interview and 2015 in detention, much of it in solitary confinement. This period included a 2005 trial that ended with acquittal on 8 counts and a hung jury on another 9. In 2015 he was deported to Turkey. In 2017, he founded the Center for Islam and Global Affairs at [[w:Istanbul Sabahattin Zaim University|Istanbul Sabahattin Zaim University]] in Istanbul, Turkey, which he directs. What has been the impact of treatment of Al-Arian on the well-being of the bottom 99 percent of the US and world population?</ref> How did these provisions get written into the Patriot Act? That's a question that deserves research, perhaps by asking elected officials in the US Congress and lobbying for their repeal. A speculation consistent with the thesis of this book is that nonviolence terrifies those who control most of they money for the media, because it threatens their ability to get their security forces to follow orders. ==3. Forbid uses of force beyond one’s own borders and covert interference in foreign countries == :''[[w:Si vis pacem, para bellum|If you want peace, prepare for war.]]'' : -- ''[[w:De Re Militari|De Re Militari]]'' by [[w:Publius Flavius Vegetius Renatus|Publius Flavius Vegetius Renatus]] (fourth or fifth century AD) The record of history is now clear: Those who prepared for war often got war initiated when one party claimed they were being attacked or about to be attacked and believed they would fare better by attacking. Sometimes this occurred when the media environment convinced leaders that their political futures required them to clandestinely provoke foreign entities to do things that could then be denounced as unprovoked to justify military escalation, as mentioned in the previous section. ===Deterrence theory and nuclear Armageddon=== Standard [[w:Deterrence theory|deterrence theory]] assumes that one's opponents are rational and do not want [[w:Armageddon|Armageddon]]. At least some portions of the [[w:Islamic State|Islamic State]] reportedly violates this assumption, because it "not only believes in the literal meaning of the coming Armageddon – it sees itself as its chief protagonist."<ref>Misra (2015).</ref> Some [[w:Christian nationalism|Christian nationalists]] promoted to command positions by [[w:United States Secretary of Defense|US Secretary of Defense]] [[w:Pete Hegseth|Hegseth]] and President Trump also seem to believe that Armageddon might be desirable. On 2026-03-03 the [[w:Military Religious Freedom Foundation|Military Religious Freedom Foundation]] said they had received over 200 complaints from over 50 different US military installations with comments like, "President Trump has been anointed by Jesus to light the signal fire in Iran to cause Armageddon and mark his return to Earth", per an email from one [[w:Non-commissioned officer|NCO]].<ref>Nick Mordowanec (2026).</ref> With Hegseth holding monthly Christian worship services in the Pentagon during business hours,<ref>Black (2025), Mayes-Osterman (2025).

Ellsberg (2017, p. 69) insisted that the security provided by those Gold Codes were a hoax, because otherwise a single nuclear detonation on Washington, DC, when both the president and vice president were in town "would would definitively block any authorized, coordinated nuclear response to that or any subsequent nuclear attack."</ref> The biggest risk today may be the risk of [[w:Nuclear holocaust|nuclear Armageddon]], which seems on average to grow over time consistent with experience with "[[w:system accidents|system accidents]]" in other fields: Managers of complex systems subject to rare, catastrophic failures "learn" from experience that they can take ever greater risks, because they have "safely" done so in the past — until there is a catastrophe:<ref>Kahneman and Klein (2009) found that expert intuition, when it exists, is learned from frequent, rapid, high quality feedback. With anything nuclear, mishaps are so rare that managers develop "expert intuition" that they can "safely" ignore safety concerns -- until there is a catastrophe. See also Sagan (1993).</ref> See also the chapter below on [[/Media Literacy and You/Responding to a nuclear attack/|Responding to a nuclear attack]]. ===Research on the effectiveness of deterrence and implications=== Lebow and others have provided substantial documentation of case studies claiming that leaders are often not rational, and deterrence based on threatening use of military force beyond one’s own borders has been ''as likely to provoke as prevent'' undesired behavior.<ref>Lebow (2025, 2024), Lebow et al. (2023).</ref> The most obvious portions of this threat can be entirely eliminated by policies clearly and effectively forbidding use of force beyond one’s own borders. This can be signaled in at least three ways: * Eliminate all weapon systems like missiles and aircraft with a range of more than, e.g., a hundred miles or 200 kilometers with the possible exception of surveillance only aircraft that cannot be easily configured to carry [[w:Materiel#Military|ordnance]], e.g., explosives. Similarly eliminate nuclear weapons, which few if any countries would want to use for military defense inside their own borders. * Supply a national guard and reserves with weapons, training, and rules of engagement that prohibit projecting force beyond one’s own borders. Train them also in development and use of improvised explosive devices and other tactics and devices like low cost military drones. :Afghanistan is said to be the "[[w:Graveyard of empires|Graveyard of empires]]". They defeated the British three times (1839–1842, 1878–1880, 1919), the Soviet Union (1979–1989), and the US (2001–2021). Each victory came with foreign supplies, but any foreign troops helping Afghanis were primarily under the command of local leaders. :The [[w:2003 invasion of Iraq|2003 invasion of Iraq]] might have produced [[w:Nation-building|nation-building]] more like the experience of [[w:Nation-building#Germany and Japan after World War II|Germany and Japan after World War II]] if the US had mandated a vigorous adversarial press instead of strict censorship, according to McChesney and Nichols.<ref>McChesney and Nichols (2010, Appendix II. Ike, MacArthur and the Forging of Free and Independent Press, pp. 241-254).</ref> This claim by McChesney and Nichols was not endorsed by [[News from Germany 1900-1945 and implications for today#After the war in Germany vs. Iraq|University of British Columbia History professor Heidi Tworek]], who said the democratization efforts in Germany and Japan after World War II were more complicated than that implied by that brief discussion by McChesney and Nichols.<ref>The 2025-07-03 interview with Tworek is available at "[[News from Germany 1900-1945 and implications for today]]", accessed 2026-05-14.</ref> However, the research by Usher and Kim-Leffingwell (2022) and the related research on news deserts summarized in the preface to this ''[[Media Literacy and You]]'' book largely supports those claims by McChesney and Nichols. :[[w:Defense industry of Ukraine|Ukraine has become a world leader in military drones]], many of which are dramatically cheaper than alternatives. Most of those have limited range but have been useful for reconnaissance and delivery of ordnance and improving targeting of, e.g., surface to air missiles. :[[w:Eliot A. Cohen|Eliot Cohen]], who served as a special advisor to [[w:United States Secretary of State|US Secretary of State]] [[w:Condoleezza Rice|Condoleezza Rice]] from 2007 to 2009, wrote, "As the United States discovered in Iraq and Afghanistan, no matter how large, technologically advanced, and proficient an army is, motivated insurgents can still inflict casualties in the tens of thousands."<ref>Cohen (2022), cited from Horton (2024, p. 1026).</ref> Cohen recommended we "Arm the Ukranians now". Horton said that the neoconservatives learned from Iraq War II and Afghanistan that the US "should fight like those who defeated them."<ref>Horton (2024, p. 1026).</ref> :Leading economist [[w:Jeffrey Sachs|Jeffrey Sachs]] addressed the European Parliament 2025-02-19, claiming that the tragedy that befell Serbia in 1999 and subsequent US uses of force in Iraq and Syria, plus wars in Africa including Syria, Somalia and Libya and the current wars in Ukraine and the Israel-Hamas war, "are to a very significant extent the result of deeply misguided US policies."<ref>Sachs (2025-02).</ref> He said that Europe should craft its own foreign and military policies, independent of the US. ''[[w:Le Monde Diplomatique|Le Monde Diplomatique]]'' noted that Sachs' speech has circulated among social media since ''but has yet to be seriously discussed by major European media.''<ref>Sachs (2025-04; emphasis added).</ref> * Change the laws of government secrecy so government officials cannot secretly interfere in the internal affairs of foreign countries or otherwise project force outside their own borders. This might be achieved in the US in part by requiring anyone with information about questionable actions by government officials to provide such documentation to one or more congressional oversight bodies while also allowing any current or former government employee or contractor to file suit in any US federal jurisdiction if they feel they have been punished for refusing to support questionable activities. In addition, federal judges should be authorized to subpoena classified government documents that may be relevant to any case in their jurisdiction and declassify them subject to appellate review if they believe the national interest would be better served by declassification. :If the law is changed without a substantive [[#1. Citizen-directed subsidies for local news nonprofits with a firewall to prevent political interference in the content.|citizen-directed subsidies for local news nonprofits with a firewall to prevent political interference]], as discussed above, the change could be merely cosmetic and unconvincing to local public officials and potential adversaries. :Connelly (2023) noted that US government secrecy has in the past encouraged administration officials to do things to provoke actions by foreign entities that can then be denounced as “unprovoked” to stampede the US Congress and the public into supporting counterproductive uses of military force, as discussed above.<ref>See also Connelly et al. (2023).</ref> A more diverse media culture should make it harder for administration officials to lie to the public and to Congress — and harder to punish government employees who tell their managers that they should not lie to Congress, as they reportedly did to [[#Richard Barlow and nuclear proliferation|Richard Barlow]], mentioned above. :The Barlow case and many others explain why the US should, e.g., give federal judges the authority to subpoena classified documents and declassify them if they believe the public good is better served from declassification than continued secrecy.<ref>See, e.g., the 2025-05-08 interview with Seth Stern and Lauren Harper discussing what the "[[Freedom of the Press Foundation says...]]", Graves (2014), and [[w:Moynihan Commission on Government Secrecy|Moynihan Commission on Government Secrecy]], accessed 2026-05-06. Graves (2021) recommends "Congressional Gold Medals for" Barlow and whistleblowers.</ref> These policies would make it hard for any foreign leader to justify an attack for multiple reasons: First, it would be difficult to convince their supporters that such an attack is necessary. Second, a rational foreign leader might be hesitant to invade a country that is prepared to fight a guerrilla war. Germany reportedly considered invading [[w:Switzerland during World War I and World War II|Switzerland during both World Wars I and II]] and decided against it in part because Switzerland had large, well-trained ready reserves, who were ready to fight. Belgium seemed to be an easier route.<ref>Documented in Wikipedia, "[[w:Switzerland during World War I and World War II|Switzerland during World War I and World War II]]", accessed 2026-05-06. Switzerland also has many mountains, which make it easier to defend, but the capabilities of the Swiss military also influenced the German decision to avoid Switzerland.</ref> Third, even if foreign invaders defeat the guerrillas, they should not assume that their invading forces would continue to follow orders. [[w:Rescue of the Danish Jews|Ninety-nine percent of Danish Jews reportedly survived World War II]] because of Danish noncooperation ''supported by a German diplomat''.<ref>Wikipedia, "[[w:Rescue of the Danish Jews|Rescue of the Danish Jews]]", accessed 2026-05-06.</ref> With policies like these in place, it would be hard for foreign leaders to convince their supporters of a need to attack, as [[w:2022 Russian invasion of Ukraine|Putin did when invading Ukraine in 2022]],<ref>The Wikipedia article on "[[w:2022 Russian invasion of Ukraine|2022 Russian invasion of Ukraine]]", accessed 2026-05-06, includes a paragraph saying, 'In July 2021, Putin published an essay "On the Historical Unity of Russians and Ukrainians", in which he called Ukraine "historically Russian lands" and claimed there is "no historical basis" for the "idea of Ukrainian people as a nation separate from the Russians"'. Putin was accused of promoting Russian imperialism, historical revisionism and disinformation. Writing in 2024, Michael McFaul and Robert Person described this essay as representing not only "cynical propaganda" but also Putin's "deeply held and internalized beliefs". See the Wikipedia article for references supporting those claims.</ref> as [[w:2025 India–Pakistan crisis|India did when attacking Pakistan in 2025]], and as [[w:Invasion of Poland|Hitler did when invading Poland in 1939]], to name only three examples. === If we continue to base deterrence on threats === There are now calls for Europe to get their own nuclear weapons,<ref>Burgard (2025).</ref> while Iran, Saudi Arabia, Turkey, South Korea and Taiwan have been suggested as other candidates for acquiring nuclear weapons should they feel a sufficient need.<ref>Ruehl (2024).</ref> It is difficult to imagine how the number of nuclear weapon states could be increased without increasing the risks of a nuclear war, consistent with the discussion of "[[w:system accident|system accident]]s" earlier in this chapter. Secondarily, intelligence services with information on political corruption including attempts to intimidate and murder journalists should not be allowed to keep that information secret: They should be required to find ways to leak that information to journalists. Such attacks on journalists in their own country should be exposed and prosecuted if the evidence seems likely to obtain a conviction. Intelligence services with information about such attacks in other countries should be required to find ways to leak it to competent journalists without identifying their sources and methods: Doing so would likely reduce political corruption worldwide and with that the risks of war. === Call for help === Do you, dear reader, know other serious research not cited herein that might improve this analysis? If yes, you can help improve this discussion by adding comments with citations -- or by adding such citation(s) to the "Discuss" page associated with this chapter, suggesting someone else revise the chapter appropriately. There are plenty of contrary claims in the major media, but the lead author of this chapter is not aware of any that are based on serious research. In the absence of such research, the current author finds it difficult to imagine any national defense policies that carry a greater risk of nuclear Armageddon than our current policies, as discussed in the next chapter of this book on ''[[Media Literacy and You]]'' on "[[Media Literacy and You/Responding to a nuclear attack|Responding to a nuclear attack]]". That chapter, in sum, claims that the ''worst'' response to a nuclear attack would be nuclear response, because it would escalate a catastrophe killing millions of humans to one killing ''billions'', possibly 80 percent of humanity in a war between the US and Russia that lofts so much smoke from burning cities to the stratosphere where it covers the globe depressing crop yields for years during with 99 percent of the humans in the US, Europe and Russia would starve to death if they did not die of something else sooner. Moreover, the record of "[[w:System accident|system accident]]s" suggests that the chances of such a war before the end of this century is substantially greater than the 40 percent median estimate based on history mentioned in a presentation on "[[Time to nuclear Armageddon]]" delivered to the 2019 Joint Statistical Meetings. This chapter is being written in the hopes of inspiring action to improve the prospects for broadly shared peace and prosperity for the long term. == Exercises == 1. Disconfirmation bias: Brainstorm your biggest concerns about a current or possible future war. :1.1. Select the one that is of greatest concern to you currently. ::One issue that may not be a major concern for many but might elicit a broad consensus for action would be a campaign to ask elected officials in the US Congress to explain how we benefit from the provisions of the USA Patriot Act of 2001 that authorize life in prison for teaching nonviolence. :1.2. Who are your designated enemies? :1.3. Research what your designated enemies are saying about your biggest concern. :1.4. Under what circumstances would you support what you see your designated enemies advocating or doing? ::If you cannot see such circumstances, expand your research: Look for more sources that support your designated enemies. 2. Interacting: Ask others if you can share what you've learned about that conflict. If they say, "No", don't push it. If they agree, share what you've learned in a friendly supportive manner without saying that anything is "true". ::''Show me someone who knows the truth, and I will show you someone who is dangerous.'' :2.1. The primary goal in this is ''not'' to convince anyone that you are right and they are wrong but to lower the level of anger and increase the level of tolerance for dissenting views. :2.2. Another goal is to comfortably enjoy civil conversations of this nature, agreeing to disagree agreeably and building trusting relationships that support collaboration on issues of common concern. :2.3. After becoming adept at building collaborations on issues of common concern, you might consider teaching this important skill and approach to issues. 3. Teaching: Each one teach two, as discussed in the section on "[[Media Literacy and You#Text and self-help book and point of discuss|Text and self-help book and point of discuss]]" in the preface to this book. <!--== See also ==--> == Notes == {{reflist}} == Bibliography == * <!--BBC (2022-08-01) "Nuclear annihilation just one miscalculation away, UN chief warns"-->{{cite Q|Q139596165|author=BBC}} * <!--Elizabeth Black (2026-05-22) "Hegseth hosts first monthly Christian service in Pentagon"-->{{cite Q|Q139791642}} * <!--Hans Günter Brauch, ed, Towards Rethinking Politics, Policy and Polity in the Anthropocene: Multidisciplinary Perspectives (Springer, pp. 225-234).-->{{cite Q|Q134488491|author= Hans Günter Brauch, ed.}} * <!--Jan Philipp Burgard (2025-04-08) “Opinion | Europe Needs Its Own Nukes”, Politico-->{{cite Q|Q134465922}} * <!--Francis X.

In contrast, AIPA targets the structural relationship between the self and the mind, aiming at durable identity reconstruction rooted in Pure Awareness rather than symptom management. ::::::The central research question of the primary AIPA preprint is whether a structured, sequentially staged method can produce permanent identity reconstruction rooted in Pure Awareness, and how such a method compares to established approaches in scope, mechanism, and outcome. :::::: == Theoretical foundations == ::::::The AIPA framework is grounded in the cognitive‑phenomenological tradition (e.g., McAdams, Varela, Metzinger, Erikson), contemporary consciousness science on minimal phenomenal experience, and qualitative methods advocacy in psychology. It builds directly on: ::::::* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. ::::::* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. ::::::* Narrative identity and partial‑self models within personality and identity theory. ::::::Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. :::::: == Experiential empiricism == ::::::The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: ::::::* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. ::::::* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). ::::::* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. ::::::* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. ::::::All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. ::::::I believe this is a valid contribution to Wikiversity. ::::::Best regards, ::::::Senad [[User:Senad Dizdarević|Senad Dizdarević]] ([[User talk:Senad Dizdarević|discuss]] • [[Special:Contributions/Senad Dizdarević|contribs]]) 06:54, 2 April 2026 (UTC) qwygbck7t5gn0ce7995w2tuv19wcz59 2809706 2809704 2026-05-16T19:24:30Z Codename Noreste 2969951 /* Unable to publish pages */ archive from [[Wikiversity:Request custodian action]] ([[mw:c:Special:MyLanguage/User:JWBTH/CD|CD]]) 2809706 wikitext text/x-wiki {{Archive|Wikiversity:Request custodian action}} == Sidewide count.js == i would like something like: [[Template:User contrib count/count.js]]. i created [[Template:User contrib count]] and a user/common.js. {{User contrib count}}.<br><br> so a "count.js" would complete it.

In contrast, AIPA targets the structural relationship between the self and the mind, aiming at durable identity reconstruction rooted in Pure Awareness rather than symptom management. ::::::The central research question of the primary AIPA preprint is whether a structured, sequentially staged method can produce permanent identity reconstruction rooted in Pure Awareness, and how such a method compares to established approaches in scope, mechanism, and outcome. :::::: == Theoretical foundations == ::::::The AIPA framework is grounded in the cognitive‑phenomenological tradition (e.g., McAdams, Varela, Metzinger, Erikson), contemporary consciousness science on minimal phenomenal experience, and qualitative methods advocacy in psychology. It builds directly on: ::::::* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. ::::::* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. ::::::* Narrative identity and partial‑self models within personality and identity theory. ::::::Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. :::::: == Experiential empiricism == ::::::The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: ::::::* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. ::::::* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). ::::::* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. ::::::* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. ::::::All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. ::::::I believe this is a valid contribution to Wikiversity. ::::::Best regards, ::::::Senad [[User:Senad Dizdarević|Senad Dizdarević]] ([[User talk:Senad Dizdarević|discuss]] • [[Special:Contributions/Senad Dizdarević|contribs]]) 06:54, 2 April 2026 (UTC) == Unable to publish pages == Whenever I try to publish a page with linked sources it gets flagged and says I'm a new user attempting to publish content with outside links.

Quoting from the reference: <blockquote> There are enormous benefits of applying AI-based solutions to monitor workers’ health and prevent accidents or, currently, COVID-19 infections, and those benefits are reported with enormous potential. According to the recent Deloitte and MedTech Europe report [11], implementing AI in European healthcare systems could save up 380,000 to 403,000 lives annually or €170.9 to 212.4 billion per year. </blockquote> Not that the reference says ''could save'', not ''saves'' as in the essay.

Quoting from the reference: <blockquote> There are enormous benefits of applying AI-based solutions to monitor workers’ health and prevent accidents or, currently, COVID-19 infections, and those benefits are reported with enormous potential. According to the recent Deloitte and MedTech Europe report [11], implementing AI in European healthcare systems could save up 380,000 to 403,000 lives annually or €170.9 to 212.4 billion per year. </blockquote> Not that the reference says ''could save'', not ''saves'' as in the essay.

Quoting from the reference: <blockquote> There are enormous benefits of applying AI-based solutions to monitor workers’ health and prevent accidents or, currently, COVID-19 infections, and those benefits are reported with enormous potential. According to the recent Deloitte and MedTech Europe report [11], implementing AI in European healthcare systems could save up 380,000 to 403,000 lives annually or €170.9 to 212.4 billion per year. </blockquote> Not that the reference says ''could save'', not ''saves'' as in the essay.

In contrast, AIPA targets the structural relationship between the self and the mind, aiming at durable identity reconstruction rooted in Pure Awareness rather than symptom management. ::::::The central research question of the primary AIPA preprint is whether a structured, sequentially staged method can produce permanent identity reconstruction rooted in Pure Awareness, and how such a method compares to established approaches in scope, mechanism, and outcome. :::::: == Theoretical foundations == ::::::The AIPA framework is grounded in the cognitive‑phenomenological tradition (e.g., McAdams, Varela, Metzinger, Erikson), contemporary consciousness science on minimal phenomenal experience, and qualitative methods advocacy in psychology. It builds directly on: ::::::* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. ::::::* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. ::::::* Narrative identity and partial‑self models within personality and identity theory. ::::::Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. :::::: == Experiential empiricism == ::::::The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: ::::::* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. ::::::* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). ::::::* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. ::::::* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. ::::::All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. ::::::I believe this is a valid contribution to Wikiversity. ::::::Best regards, ::::::Senad [[User:Senad Dizdarević|Senad Dizdarević]] ([[User talk:Senad Dizdarević|discuss]] • [[Special:Contributions/Senad Dizdarević|contribs]]) 06:54, 2 April 2026 (UTC) == Unable to publish pages == Whenever I try to publish a page with linked sources it gets flagged and says I'm a new user attempting to publish content with outside links.

Quoting from the reference: <blockquote> There are enormous benefits of applying AI-based solutions to monitor workers’ health and prevent accidents or, currently, COVID-19 infections, and those benefits are reported with enormous potential. According to the recent Deloitte and MedTech Europe report [11], implementing AI in European healthcare systems could save up 380,000 to 403,000 lives annually or €170.9 to 212.4 billion per year. </blockquote> Not that the reference says ''could save'', not ''saves'' as in the essay.

In contrast, AIPA targets the structural relationship between the self and the mind, aiming at durable identity reconstruction rooted in Pure Awareness rather than symptom management. ::::::The central research question of the primary AIPA preprint is whether a structured, sequentially staged method can produce permanent identity reconstruction rooted in Pure Awareness, and how such a method compares to established approaches in scope, mechanism, and outcome. :::::: == Theoretical foundations == ::::::The AIPA framework is grounded in the cognitive‑phenomenological tradition (e.g., McAdams, Varela, Metzinger, Erikson), contemporary consciousness science on minimal phenomenal experience, and qualitative methods advocacy in psychology. It builds directly on: ::::::* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. ::::::* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. ::::::* Narrative identity and partial‑self models within personality and identity theory. ::::::Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. :::::: == Experiential empiricism == ::::::The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: ::::::* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. ::::::* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). ::::::* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. ::::::* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. ::::::All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. ::::::I believe this is a valid contribution to Wikiversity. ::::::Best regards, ::::::Senad [[User:Senad Dizdarević|Senad Dizdarević]] ([[User talk:Senad Dizdarević|discuss]] • [[Special:Contributions/Senad Dizdarević|contribs]]) 06:54, 2 April 2026 (UTC) == Unable to publish pages == Whenever I try to publish a page with linked sources it gets flagged and says I'm a new user attempting to publish content with outside links.

Quoting from the reference: <blockquote> There are enormous benefits of applying AI-based solutions to monitor workers’ health and prevent accidents or, currently, COVID-19 infections, and those benefits are reported with enormous potential. According to the recent Deloitte and MedTech Europe report [11], implementing AI in European healthcare systems could save up 380,000 to 403,000 lives annually or €170.9 to 212.4 billion per year. </blockquote> Not that the reference says ''could save'', not ''saves'' as in the essay.

In contrast, AIPA targets the structural relationship between the self and the mind, aiming at durable identity reconstruction rooted in Pure Awareness rather than symptom management. ::::::The central research question of the primary AIPA preprint is whether a structured, sequentially staged method can produce permanent identity reconstruction rooted in Pure Awareness, and how such a method compares to established approaches in scope, mechanism, and outcome. :::::: == Theoretical foundations == ::::::The AIPA framework is grounded in the cognitive‑phenomenological tradition (e.g., McAdams, Varela, Metzinger, Erikson), contemporary consciousness science on minimal phenomenal experience, and qualitative methods advocacy in psychology. It builds directly on: ::::::* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. ::::::* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. ::::::* Narrative identity and partial‑self models within personality and identity theory. ::::::Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. :::::: == Experiential empiricism == ::::::The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: ::::::* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. ::::::* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). ::::::* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. ::::::* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. ::::::All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. ::::::I believe this is a valid contribution to Wikiversity. ::::::Best regards, ::::::Senad [[User:Senad Dizdarević|Senad Dizdarević]] ([[User talk:Senad Dizdarević|discuss]] • [[Special:Contributions/Senad Dizdarević|contribs]]) 06:54, 2 April 2026 (UTC) == Unable to publish pages == Whenever I try to publish a page with linked sources it gets flagged and says I'm a new user attempting to publish content with outside links.

It builds directly on: ::::::* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. ::::::* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. ::::::* Narrative identity and partial‑self models within personality and identity theory. ::::::Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. :::::: == Experiential empiricism == ::::::The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: ::::::* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. ::::::* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). ::::::* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. ::::::* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. ::::::All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. ::::::I believe this is a valid contribution to Wikiversity. ::::::Best regards, ::::::Senad [[User:Senad Dizdarević|Senad Dizdarević]] ([[User talk:Senad Dizdarević|discuss]] • [[Special:Contributions/Senad Dizdarević|contribs]]) 06:54, 2 April 2026 (UTC) == Unable to publish pages == Whenever I try to publish a page with linked sources it gets flagged and says I'm a new user attempting to publish content with outside links.

In contrast, AIPA targets the structural relationship between the self and the mind, aiming at durable identity reconstruction rooted in Pure Awareness rather than symptom management. ::::::The central research question of the primary AIPA preprint is whether a structured, sequentially staged method can produce permanent identity reconstruction rooted in Pure Awareness, and how such a method compares to established approaches in scope, mechanism, and outcome. :::::: == Theoretical foundations == ::::::The AIPA framework is grounded in the cognitive‑phenomenological tradition (e.g., McAdams, Varela, Metzinger, Erikson), contemporary consciousness science on minimal phenomenal experience, and qualitative methods advocacy in psychology. It builds directly on: ::::::* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. ::::::* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. ::::::* Narrative identity and partial‑self models within personality and identity theory. ::::::Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. :::::: == Experiential empiricism == ::::::The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: ::::::* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. ::::::* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). ::::::* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. ::::::* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. ::::::All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. ::::::I believe this is a valid contribution to Wikiversity. ::::::Best regards, ::::::Senad [[User:Senad Dizdarević|Senad Dizdarević]] ([[User talk:Senad Dizdarević|discuss]] • [[Special:Contributions/Senad Dizdarević|contribs]]) 06:54, 2 April 2026 (UTC) == Unable to publish pages == Whenever I try to publish a page with linked sources it gets flagged and says I'm a new user attempting to publish content with outside links.

Take for rexample the sentence: <blockquote> Due to its efficiency, AI has saved 380,000-403,000 lives per year in European healthcare as reported in a recent Deloitte and MedTech Europe report<ref>Dantas, C., Mackiewicz, K., Tageo, V., Jacucci, G., Guardado, D., Ortet, S., Varlamis, I., Maniadakis, M., De Lera, E., Quintas, J., Kocsis, O., & Vassiliou, C.

Quoting from the reference: <blockquote> There are enormous benefits of applying AI-based solutions to monitor workers’ health and prevent accidents or, currently, COVID-19 infections, and those benefits are reported with enormous potential. According to the recent Deloitte and MedTech Europe report [11], implementing AI in European healthcare systems could save up 380,000 to 403,000 lives annually or €170.9 to 212.4 billion per year. </blockquote> Not that the reference says ''could save'', not ''saves'' as in the essay.

In contrast, AIPA targets the structural relationship between the self and the mind, aiming at durable identity reconstruction rooted in Pure Awareness rather than symptom management. ::::::The central research question of the primary AIPA preprint is whether a structured, sequentially staged method can produce permanent identity reconstruction rooted in Pure Awareness, and how such a method compares to established approaches in scope, mechanism, and outcome. :::::: == Theoretical foundations == ::::::The AIPA framework is grounded in the cognitive‑phenomenological tradition (e.g., McAdams, Varela, Metzinger, Erikson), contemporary consciousness science on minimal phenomenal experience, and qualitative methods advocacy in psychology. It builds directly on: ::::::* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. ::::::* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. ::::::* Narrative identity and partial‑self models within personality and identity theory. ::::::Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. :::::: == Experiential empiricism == ::::::The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: ::::::* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. ::::::* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). ::::::* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. ::::::* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. ::::::All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. ::::::I believe this is a valid contribution to Wikiversity. ::::::Best regards, ::::::Senad [[User:Senad Dizdarević|Senad Dizdarević]] ([[User talk:Senad Dizdarević|discuss]] • [[Special:Contributions/Senad Dizdarević|contribs]]) 06:54, 2 April 2026 (UTC) == Unable to publish pages == Whenever I try to publish a page with linked sources it gets flagged and says I'm a new user attempting to publish content with outside links.

This makes learning more practical and useful, especially for those who want to understand how real work environments function. ::'''Background''' ::The concept of online learning developed from distance education, where students learned from remote locations. Over time, with the growth of digital technology, learning has become more interactive and flexible. ::The introduction of the online internship has added another important layer to digital education. It combines theoretical learning with practical experience, helping students prepare for future careers. ::During global events such as the COVID-19 pandemic, online education and online internship programs became essential. They helped students continue learning and gaining experience despite restrictions on physical movement. ::'''Importance of Online Internship''' ::An online internship plays an important role in student development. It helps bridge the gap between academic knowledge and practical skills. ::'''Some key points include:''' ::Students understand how real work is done ::They develop basic professional skills ::It supports career readiness ::It allows learning without location limits ::By participating in an online internship, students can improve their confidence and gain early exposure to different fields. ::'''Features of Online Internship-Based Learning''' ::Modern education platforms often include online internship opportunities as part of their learning system.

Myself and students use some AI-generated images in the [[Motivation and emotion]] project. [[User:Dronebogus]] has been removing some of these images from Wikiversity pages and nominating them for deletion at Commons. As a result, some have been deleted and some have been kept. Dronebogus has made some useful edits and image suggestions for [[Motivation and emotion]] which I've appreciated and incorporated. However, there are other edits to remove an AI image by Dronebogus that I've reverted where I think the image is more educational than no image or an alternative image suggested by Dronebogus. There are a couple of pages where Dronebogus has reverted my reversion, so we are at risk of edit warring. We have briefly discussed and warned each other on our user talk pages, but it seems to come down to a difference in perception about the educational usefulness of the AI images. So, I'm asking here for others to please review the recent edit histories for these pages: * [[Motivation and emotion/Lectures/Brain and physiological needs]] * [[Motivation and emotion/Book/2025/Stockholm syndrome emotion]] and let us know what you think about the AI image suitability vs. using no image or alternative images suggested by Dronebogus.

It builds directly on: ::::::* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. ::::::* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. ::::::* Narrative identity and partial‑self models within personality and identity theory. ::::::Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. :::::: == Experiential empiricism == ::::::The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: ::::::* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. ::::::* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). ::::::* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. ::::::* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. ::::::All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. ::::::I believe this is a valid contribution to Wikiversity. ::::::Best regards, ::::::Senad [[User:Senad Dizdarević|Senad Dizdarević]] ([[User talk:Senad Dizdarević|discuss]] • [[Special:Contributions/Senad Dizdarević|contribs]]) 06:54, 2 April 2026 (UTC) == Unable to publish pages == Whenever I try to publish a page with linked sources it gets flagged and says I'm a new user attempting to publish content with outside links.

[[User:Dronebogus]] has been removing some of these images from Wikiversity pages and nominating them for deletion at Commons. As a result, some have been deleted and some have been kept. Dronebogus has made some useful edits and image suggestions for [[Motivation and emotion]] which I've appreciated and incorporated. However, there are other edits to remove an AI image by Dronebogus that I've reverted where I think the image is more educational than no image or an alternative image suggested by Dronebogus. There are a couple of pages where Dronebogus has reverted my reversion, so we are at risk of edit warring. We have briefly discussed and warned each other on our user talk pages, but it seems to come down to a difference in perception about the educational usefulness of the AI images. So, I'm asking here for others to please review the recent edit histories for these pages: * [[Motivation and emotion/Lectures/Brain and physiological needs]] * [[Motivation and emotion/Book/2025/Stockholm syndrome emotion]] and let us know what you think about the AI image suitability vs. using no image or alternative images suggested by Dronebogus.

These images, such as [[:File:Redfield equation (non-Markovian).png]] and [[:File:Lindblad equation (Markovian).png]], don't even match the text he puts them with.

In contrast, AIPA targets the structural relationship between the self and the mind, aiming at durable identity reconstruction rooted in Pure Awareness rather than symptom management. ::::::The central research question of the primary AIPA preprint is whether a structured, sequentially staged method can produce permanent identity reconstruction rooted in Pure Awareness, and how such a method compares to established approaches in scope, mechanism, and outcome. :::::: == Theoretical foundations == ::::::The AIPA framework is grounded in the cognitive‑phenomenological tradition (e.g., McAdams, Varela, Metzinger, Erikson), contemporary consciousness science on minimal phenomenal experience, and qualitative methods advocacy in psychology. It builds directly on: ::::::* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. ::::::* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. ::::::* Narrative identity and partial‑self models within personality and identity theory. ::::::Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. :::::: == Experiential empiricism == ::::::The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: ::::::* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. ::::::* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). ::::::* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. ::::::* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. ::::::All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. ::::::I believe this is a valid contribution to Wikiversity. ::::::Best regards, ::::::Senad [[User:Senad Dizdarević|Senad Dizdarević]] ([[User talk:Senad Dizdarević|discuss]] • [[Special:Contributions/Senad Dizdarević|contribs]]) 06:54, 2 April 2026 (UTC) == Unable to publish pages == Whenever I try to publish a page with linked sources it gets flagged and says I'm a new user attempting to publish content with outside links.

Quoting from the reference: <blockquote> There are enormous benefits of applying AI-based solutions to monitor workers’ health and prevent accidents or, currently, COVID-19 infections, and those benefits are reported with enormous potential. According to the recent Deloitte and MedTech Europe report [11], implementing AI in European healthcare systems could save up 380,000 to 403,000 lives annually or €170.9 to 212.4 billion per year. </blockquote> Not that the reference says ''could save'', not ''saves'' as in the essay.

In contrast, AIPA targets the structural relationship between the self and the mind, aiming at durable identity reconstruction rooted in Pure Awareness rather than symptom management. ::::::The central research question of the primary AIPA preprint is whether a structured, sequentially staged method can produce permanent identity reconstruction rooted in Pure Awareness, and how such a method compares to established approaches in scope, mechanism, and outcome. :::::: == Theoretical foundations == ::::::The AIPA framework is grounded in the cognitive‑phenomenological tradition (e.g., McAdams, Varela, Metzinger, Erikson), contemporary consciousness science on minimal phenomenal experience, and qualitative methods advocacy in psychology. It builds directly on: ::::::* Empirical work on pure awareness and Minimal Phenomenal Experience (MPE), especially Gamma & Metzinger’s large‑scale study of content‑reduced awareness states. ::::::* Metzinger’s proposal of minimal phenomenal experience as an entry point for a minimal unifying model of consciousness. ::::::* Narrative identity and partial‑self models within personality and identity theory. ::::::Within this backdrop, AIPA proposes Pure Awareness as a distinct, operationally specified state that can become a structural ground of identity rather than a transient meditative experience. :::::: == Experiential empiricism == ::::::The empirical foundation of the AIPA Method is explicitly first‑person and experiential, combining: ::::::* A 22‑year longitudinal autoethnographic self‑study (2003–2025) documenting partial personality episodes, protocol use, and outcomes. ::::::* A 13‑year prospective verification period with zero self‑reported recurrence of targeted harmful behaviors after a dated stabilization point (1 January 2006). ::::::* A high‑ecological‑validity “stress test” during acute bereavement, used to examine whether non‑reactive awareness remains stable under maximal provocation. ::::::* Two independent practitioner cases (an Amazon‑verified report and a structured questionnaire case) providing preliminary convergent signals across cognitive, emotional, behavioral, and identity dimensions. ::::::All central constructs (Pure Awareness, partial personalities, the Switch, identity stabilization) are operationalized with explicit phenomenological and behavioral criteria intended to enable replication and future third‑person measurement. ::::::I believe this is a valid contribution to Wikiversity. ::::::Best regards, ::::::Senad [[User:Senad Dizdarević|Senad Dizdarević]] ([[User talk:Senad Dizdarević|discuss]] • [[Special:Contributions/Senad Dizdarević|contribs]]) 06:54, 2 April 2026 (UTC) == Unable to publish pages == Whenever I try to publish a page with linked sources it gets flagged and says I'm a new user attempting to publish content with outside links.

This makes learning more practical and useful, especially for those who want to understand how real work environments function. ::'''Background''' ::The concept of online learning developed from distance education, where students learned from remote locations. Over time, with the growth of digital technology, learning has become more interactive and flexible. ::The introduction of the online internship has added another important layer to digital education. It combines theoretical learning with practical experience, helping students prepare for future careers. ::During global events such as the COVID-19 pandemic, online education and online internship programs became essential.

Myself and students use some AI-generated images in the [[Motivation and emotion]] project. [[User:Dronebogus]] has been removing some of these images from Wikiversity pages and nominating them for deletion at Commons. As a result, some have been deleted and some have been kept. Dronebogus has made some useful edits and image suggestions for [[Motivation and emotion]] which I've appreciated and incorporated. However, there are other edits to remove an AI image by Dronebogus that I've reverted where I think the image is more educational than no image or an alternative image suggested by Dronebogus. There are a couple of pages where Dronebogus has reverted my reversion, so we are at risk of edit warring. We have briefly discussed and warned each other on our user talk pages, but it seems to come down to a difference in perception about the educational usefulness of the AI images. So, I'm asking here for others to please review the recent edit histories for these pages: * [[Motivation and emotion/Lectures/Brain and physiological needs]] * [[Motivation and emotion/Book/2025/Stockholm syndrome emotion]] and let us know what you think about the AI image suitability vs. using no image or alternative images suggested by Dronebogus.

If you use it, it should be the last resort of last resorts. Just my stance, which I consider perfectly valid and reasonable.

The most common of them is the 5-string banjo, usually for playing bluegrass, folk, or old-time music. The next most common is the 4-string tenor banjo, usually for playing Irish traditional music or jazz. Many other hybrid and modified versions of the banjo exist including banjitar, gourd banjo, long neck banjo, and more. ''To read more on the etymology, history, and types of banjos, I recommend the "Banjo - Wikipedia"[https://en.wikipedia.org/wiki/Banjo] website.'' == Types of Banjos == === 5-String Banjo === The standard 5-string banjo is defined by four strings tuned at the headstock, and a fifth string that is the same gauge as the first, but starts from the fifth fret, three-quarters the length of the other strings. It would have 22 frets along a length of between 25.5-27 inches. This often will come with a removable resonator allowing the instrument to be configured either as a resonator banjo or as an open-back banjo. The most common playing styles include clawhammer, three-finger bluegrass, melodic (keith) style, and chromatic style. ==== Long neck banjos ==== The long-neck banjo is a variant of the standard 5-string banjo having an extended neck with three additional frets, allowing the instrument to be played in lower pitch ranges while retaining standard banjo tuning relationships. The scale length can range from 28-32 inches. This instrument was invented by Pete Seeger in 1944 when he had a luthier, John D'Angelico, modify his banjo to add two extra frets. That banjo would be stolen a five years later and he would commission one with three extra frets which he would popularize throughout the 1950's and 60's folk scene.<ref>{{Cite web|url=https://banjonews.com/2014-03/the_seeger_long_neck_americas_third_banjo.html|title=Banjo Newsletter|website=banjonews.com|access-date=2026-05-16}}</ref> === 4-String Tenor Banjo === The four-string plectrum banjo is a standard banjo without the short drone string, consisting of the same number of frets and neck size. This banjo is usually played with a guitar-like pick. === Banjo Hybrids and Variations === Most banjo hybrids combine the acoustic drum-head of a banjo with the playing and tuning style of the different instrument. These include the guitar banjo (banjitar), mandolin banjo (banjolin), ukelele banjo (banjolele), dobro banjo (dojo), cello banjo (celljo), bass banjo (bassjo), lute banjo, the electric banjo, and even a violin banjo.

The gourd banjo and mountain banjos are also considered variations. == Techniques == * Frailing (Clawhammer, Round Peak) * Fingerpicking (Scruggs Style, Two-finger, Melodic (Keith) Style, Chromatic) == Sources == [[Category:Music instruments]] 78ti9j77qfox48qwm66ssr1dg2nfazq Talk:Amazon Web Services 1 329680 2809735 2026-05-16T19:34:54Z ~2026-29534-16 3076751 /* Amar samson */ new section 2809735 wikitext text/x-wiki == Amar samson == amar [[Special:Contributions/&#126;2026-29534-16|&#126;2026-29534-16]] ([[User talk:&#126;2026-29534-16|talk]]) 19:34, 16 May 2026 (UTC) afj4ep0solstxfjaw2v9wmnaa0y3032 2809737 2809735 2026-05-16T19:56:55Z Atcovi 276019 {{Talk header}} 2809737 wikitext text/x-wiki {{Talk header}} 6ujz0t3lkt6jsf7d1r360l6l7wj3njb Template:Talk header/styles.css 10 329681 2809738 2026-03-30T20:01:58Z w>Mathglot 0 Restore .talkheader-newtopic. 2809738 sanitized-css text/css /* {{pp-template}} */ /* Talk header styles */ .talkheader { text-align: center; } .talkheader-body { display: flex; } .talkheader-help, .talkheader-policies, .talkheader-shortcuts { display: flex; align-items: center; padding: 0.1em; } .talkheader-help { flex: 2 1 auto; border: 1px solid #c0c090; background-color: var(--background-color-base, #ffffff); color: inherit; } .talkheader-policies { flex: 1 1 auto; } .talkheader-policies + .talkheader-policies { border-left: 1px solid #c0c090; } .talkheader-shortcuts { flex: 0 1 auto; } .talkheader-help > *, .talkheader-policies > *, .talkheader-shortcuts > * { flex: 1 1 auto; } .talkheader-help ul, .talkheader-policies ul { margin: 0.1em 0.8em 0 1.6em; text-align: left; } .talkheader-newtopic { text-align: center; font-weight: bold; list-style: none; list-style-position: outside; /* the default */ } @media (min-width: 720px) { .talkheader { min-width: 80%; } } d77t4objkm94z3gfuz70k5u5u19vweu 2809739 2809738 2026-05-16T20:10:11Z Codename Noreste 2969951 1 revision imported from [[:w:Template:Talk_header/styles.css]]: Required to implement dark mode support on [[Template:Talk header]]. 2809738 sanitized-css text/css /* {{pp-template}} */ /* Talk header styles */ .talkheader { text-align: center; } .talkheader-body { display: flex; } .talkheader-help, .talkheader-policies, .talkheader-shortcuts { display: flex; align-items: center; padding: 0.1em; } .talkheader-help { flex: 2 1 auto; border: 1px solid #c0c090; background-color: var(--background-color-base, #ffffff); color: inherit; } .talkheader-policies { flex: 1 1 auto; } .talkheader-policies + .talkheader-policies { border-left: 1px solid #c0c090; } .talkheader-shortcuts { flex: 0 1 auto; } .talkheader-help > *, .talkheader-policies > *, .talkheader-shortcuts > * { flex: 1 1 auto; } .talkheader-help ul, .talkheader-policies ul { margin: 0.1em 0.8em 0 1.6em; text-align: left; } .talkheader-newtopic { text-align: center; font-weight: bold; list-style: none; list-style-position: outside; /* the default */ } @media (min-width: 720px) { .talkheader { min-width: 80%; } } d77t4objkm94z3gfuz70k5u5u19vweu 2809741 2809739 2026-05-16T20:15:30Z Codename Noreste 2969951 Protected "[[Template:Talk header/styles.css]]": Matching the parent protection as the template.

Ever since this brand was launched, it continues to become a go to fashion and advocacy brand that consistently supports women. As the company continues to grow in the competitive e-commerce industry, maintaining a stable and protected information system becomes one of the most important responsibilities of the organization. This maintenance and continuity plan is made to ensure that the business remains secured and prepared for unexpected technical problems. Ultimately, this document is not only created to prevent system failures but also to provide clear recovery procedures in case emergencies happen. ---- ==== ''Step 1: Regular System Maintenance'' ==== The website, application used, and transaction system shall be monitored daily to prevent delays and technical errors. Every software updates and security patches shall also be installed regularly to keep the platform stable and protected from cyber threats. ==== ''Step 2: Data Backup and Recovery'' ==== Every important records such as customer orders, payment records, and inventory data shall be backed up every 6 hours and a full-blown backup shall also be performed weekly so that the company is assured that important information can still be recovered during system failures. ==== ''Step 3: Security Protection'' ==== Every employee accounts that are used to communicate with company details must use strong passwords and Two-Factor Authentication (2FA). Confidential and sensitive information shall only be accessed by authorized staff. ==== ''Step 4: Emergency Response Plan'' ==== If the system crashes, the IT Support Team shall immediately activate the backup server and begin data recovery procedures. Customers shall also be informed about service interruptions. For example, during large online sales like Shopee’s 11.11 or 12.12 events, sudden traffic overloads can cause temporary outages, which is why having a fast recovery and backup system is important to avoid losing sales and customer trust. e1yw1y2s1jcmal7zmpebroqgex81iie User:IgnorantObserver/sandbox 2 329702 2809879 2026-05-17T09:21:44Z IgnorantObserver 3076980 Step 1/2: initial page creation in sandbox (external links to be added in follow-up edit).

Page text is offered for review, critique, and collaborative refinement under [[Wikiversity:Copyrights|Wikiversity's standard licence]].'' == Status == Research project under active development. The framework consists of an interlinked set of technical and interpretive documents published at ignorantobserver.xyz and archived on the Open Science Framework. The technical module ''Bandwidth-Limited Quantum Control'' (BLQC) sets out the framework's falsifiable experimental discriminator. The broader ''Ignorant Observer Framework'' (IOF) connects this technical core to questions in the foundations of quantum mechanics and the philosophy of mind. All work is single-authored. == Summary == The Ignorant Observer Framework proposes that the conventional treatment of quantum measurement idealizes the measurement basis as stably available to the observer. The framework removes that idealization. It treats the measurement basis θ as a physical dynamical variable inside the apparatus, with its own causal history and its own information-production rate. Whether the apparatus can stably track θ is then a control-theoretic question, governed by an inequality between effective information-channel capacity and the basis-defining dynamics' entropy rate. ''Bandwidth-Limited Quantum Control'' (BLQC), the framework's technical module, derives — under the assumptions catalogued in the [[#Open objections|Open objections]] section below — a distinctive ''double-exponential'' visibility decay law and a corresponding falsifiable experimental signature: under variation of controller input power at clamped environmental temperature, the framework predicts that coherence time should ''lengthen'' with increasing power, the opposite of standard thermal decoherence. This sign-reversal is the central testable claim. The framework as a whole also offers an interpretive extension that connects the technical proposal to existing positions in quantum foundations (Brukner, Rovelli's relational quantum mechanics) and to non-dual philosophy of mind (Advaita Vedānta). These interpretive elements are clearly fenced from the empirical core in [[#Philosophical interpretation|the relevant section below]]. What stands or falls with the experimental discriminator is the framework's specific physical mapping into these positions, not the positions themselves. == Core question == ''Can quantum visibility depend on finite observer or apparatus basis-tracking capacity, independently of, and distinguishably from, ordinary environmental decoherence?'' Phrased positively: if the classical degrees of freedom that define and maintain a measurement basis exhibit chaotic dynamics with positive Kolmogorov–Sinai entropy rate ''h''<sub>KS</sub>, and if the effective information channel that constrains those degrees of freedom has capacity ''C''<sub>eff</sub> insufficient to track them, does interference visibility decay in a functional form distinguishable from standard exponential or Gaussian dephasing — and does this decay respond to controller input power in a direction opposite to thermal decoherence? == Technical proposal == The framework introduces the following quantities. '''Effective channel capacity ''C''<sub>eff</sub>''' (bits/s): the information rate available to the basis-tracking control loop, operationalised as :''C''<sub>eff</sub> = ''r'' · ''b'' · ''f'' with ''r'' the update rate (Hz), ''b'' the effective number of bits per update that constrain the basis variable θ, and ''f'' ∈ (0,1] the fraction of updates that genuinely constrain θ after overhead and latency. ''C''<sub>eff</sub> is bounded above by the Landauer limit on the controller's actuation: :''C''<sub>eff</sub> ≤ ''P'' / (''k''<sub>B</sub> ''T'' ln 2) where ''P'' is controller input power and ''T'' is the temperature at which the controller operates. '''Kolmogorov–Sinai entropy rate ''h''<sub>KS</sub>''' (nats/s): the information-production rate of the classical degrees of freedom (voltage references, timing circuits, feedback loops) that define and maintain the measurement basis. For chaotic systems, ''h''<sub>KS</sub> equals the sum of positive Lyapunov exponents (Pesin identity). It is estimated operationally from the exponential growth of one-step prediction error on logged controller states. The nats/s convention is used so that the deficit κ below combines ''h''<sub>KS</sub> (nats/s) and ''C''<sub>eff</sub> ln 2 (bits/s converted to nats/s) in consistent units; an equivalent all-bits form would be κ<sub>bits</sub> = ''h''<sub>KS,bits</sub> − ''C''<sub>eff</sub>. '''Ignorance rate κ''' (s<sup>−1</sup>): :κ = ''h''<sub>KS</sub> − ''C''<sub>eff</sub> · ln 2 The framework distinguishes two regimes. When κ < 0 (''capacity-wins''), basis-tracking error stays bounded and standard quantum mechanics is recovered. When κ > 0 (''chaos-wins''), the variance of the basis-tracking error grows exponentially in time as σ<sub>θ</sub><sup>2</sup>(''t'') = σ<sub>0</sub><sup>2</sup> e<sup>2κ''t''</sup>. '''Measured visibility ''V''(''t'')'''. Averaging the interference term cos(φ − θ) over a Gaussian distribution of basis-tracking error δθ ∼ ''N''(0, σ<sub>θ</sub><sup>2</sup>(''t'')) yields, in the small-angle regime, :''V''(''t'') = exp(−½ σ<sub>0</sub><sup>2</sup> e<sup>2κ''t''</sup>) i.e. a ''double-exponential'' decay of visibility once the chaos-wins regime is entered. '''Breakdown time ''t''<sub>break</sub>'''. For a chosen visibility threshold ''V''*, :''t''<sub>break</sub> = (1 / 2κ) · ln(−2 ln ''V''* / σ<sub>0</sub><sup>2</sup>) for κ > 0. ''t''<sub>break</sub> is the framework's primary observable. The technical derivation extends the Data-Rate Theorem of Nair & Evans (2004) and Tatikonda & Mitter (2004) from linear plants to nonlinear, chaotic systems by substituting ''h''<sub>KS</sub> for the sum-of-positive-eigenvalues bound. This extension is an explicit assumption of the framework rather than a proven theorem (see [[#Open objections|Open objections]]). == Experimental discriminator == The framework prescribes the following experimental protocol as its central falsifiable test. '''Independent variable''': controller input power ''P''. The controller is the physical system whose state defines and maintains the measurement basis (e.g. an interferometer phase-locking loop, a qubit readout chain, the active feedback in a precision interferometer). '''Held constant''': the environmental temperature ''T'' at which the controller operates, by independent active thermal feedback. Holding ''T'' constant while varying ''P'' is what distinguishes the framework's prediction from standard thermal decoherence (which depends on ''T'' and ignores ''P''). '''Dependent variable''': the visibility-decay breakdown time ''t''<sub>break</sub>, fitted to interference data at a chosen visibility threshold (e.g. ''V''* = 0.5). '''Prediction''': ∂''t''<sub>break</sub>/∂''P'' > 0 at clamped ''T'', with the visibility curve ''V''(''t'') fitting the double-exponential form exp(−½ σ<sub>0</sub><sup>2</sup> e<sup>2κ''t''</sup>) better than a standard exponential ''e''<sup>−Γ''t''</sup> or Gaussian ''e''<sup>−γ''t''²</sup>. '''What would count as falsification'''. Any of the following null findings counts against the framework: * ∂''t''<sub>break</sub>/∂''P'' ≤ 0 at clamped ''T'' (i.e. increasing controller power does not extend, or shortens, coherence time); * ''V''(''t'') fits a single-exponential or Gaussian dephasing law significantly better than the double-exponential form, in the regime where the framework predicts the double-exponential should dominate; * ''t''<sub>break</sub> scales with the gravitational self-energy timescale ''t''<sub>OR</sub> ∝ ''s'' / ''m''<sup>2</sup> (the [[Penrose interpretation of quantum mechanics|Penrose Objective Reduction]] prediction) rather than with ''C''<sub>eff</sub>; * ''C''<sub>eff</sub> cannot be calibrated independently of ''t''<sub>break</sub> (in which case the prediction would be unfalsifiable, which would itself count against the framework's experimental status). The QGEM pathfinder is cited in the BLQC manuscript as one candidate testbed; superconducting-qubit readout chains and precision interferometer phase-locking loops are others. == Relation to quantum foundations == The framework is connected to, and partly draws from, several existing positions in the foundations of quantum mechanics. * '''Brukner's information-theoretic reconstructions''' provide a precedent for treating information limits as structural constraints in quantum theory. * '''Relational Quantum Mechanics''' (Rovelli) takes measurement outcomes to be relative to an observer-system; the framework provides one possible mechanism (finite ''C''<sub>eff</sub>) for what makes one observer's frame physically inequivalent to another's. * '''Decoherence theory''' is not opposed by the framework. The framework's prediction sits beside ordinary environmental decoherence and is intended to be ''distinguishable'' from it by the sign-reversal under power variation; in the capacity-wins regime (κ < 0) standard decoherence theory is recovered. * '''Measurement-independence'''. Because the framework treats the measurement basis as a dynamical variable with its own causal history, if extended to Bell-type set-ups it appears to imply a structural violation of statistical measurement-independence. The framework's response to the conventional "conspiracy" objection against superdeterminism is to attribute the correlation to common causal past plus a global consistency constraint rather than to fine-tuned initial conditions. This response is philosophical rather than mathematical and the formal extension (including a no-signalling treatment) is itself an open question (see [[#Open objections|Open objections]]). * '''Penrose Objective Reduction''' is treated as an ''orthogonal'' competing mechanism whose predicted ''t''<sub>OR</sub> ∝ ''s'' / ''m''<sup>2</sup> scaling can be experimentally distinguished from the framework's ''C''<sub>eff</sub>-driven ''t''<sub>break</sub>. The numerical proximity of the two timescales in the mesoscopic regime motivates the protocol described in the next section but is treated as a coincidence pending experimental evidence. == Philosophical interpretation == ''This section describes interpretive extensions of the framework that go beyond the empirical core. Nothing in this section is a load-bearing element of the experimental claim. If the experimental discriminator returns a null result, the claimed physical realization of these interpretive readings within the framework would fall. The interpretive positions themselves — Advaita Vedānta, relational quantum mechanics — do not stand or fall on an interferometry experiment; what stands or falls is the framework's specific physical mapping into them.'' A direct statement of the framework's interpretive position appears in ''The Hard Problem Dissolved — But Into What? A Critical Response to Carlo Rovelli's "There Is No 'Hard Problem of Consciousness'"'' (Dekker, May 2026). The response engages Rovelli's recent Noema essay, marks the substantial ground it shares with the framework, and identifies where the framework presses beyond Rovelli's deflationary physicalism toward a non-dual reading. Readers approaching the framework from philosophy of mind may find that essay the most accessible entry point. The framework's interpretive layer is developed in dialogue with two existing positions. The first is Carlo Rovelli's relational quantum mechanics. The framework can be read as supplying a candidate physical mechanism — the ''C''<sub>eff</sub> versus ''h''<sub>KS</sub> inequality — for what makes a measurement outcome relative to an observer rather than absolute. On this reading, the framework is a mechanistic specification of an idea that RQM leaves at the level of principle. The second is the Advaita Vedānta tradition (Śaṅkara, Ramaṇa Mahaṛṣi), in which the apparent independence of the experiencing subject from the perceived world is treated as a structural feature of ignorance (''avidyā'') rather than a metaphysical fact. The framework's σ<sub>θ</sub><sup>2</sup>(''t'') — the growing basis-tracking error of an observer whose capacity is insufficient to track its own apparatus — admits a structural analogy with avidyā as the phenomenological self-opacity of an embodied subject. The framework neither asserts that this analogy is more than structural nor that any experimental result could confirm or refute Advaita as a philosophical position; it offers the analogy as a way of locating the framework within a non-dual reading of the measurement problem for readers who find that reading useful. Readers who prefer to ignore both interpretive readings should be able to evaluate the framework's empirical content from the [[#Technical proposal|Technical proposal]] and [[#Experimental discriminator|Experimental discriminator]] sections alone. A further speculative extension, ''The Creation of Duality'', asks whether space, time, objecthood, and gravity-like structure can themselves be read as features of a consistent finite-observer world-model, with a Bridge Ansatz ''E''<sub>G</sub> = (π/2)ℏκ linking the deficit rate κ to a gravitational energy scale via Margolus–Levitin saturation. Its scientific status is contingent on the BLQC experimental discriminator; until then it is offered explicitly as speculation. == Documents == The framework's documents are published at ignorantobserver.xyz. Direct links to the principal documents: * '''Bandwidth-Limited Quantum Control''' — finite-rate phase-reference test in the Penrose-overlap regime. The framework's falsifiable experimental discriminator. * '''The Ignorant Observer''' — main framework document. Physical formalization inspired by Advaita Vedanta's insight into ignorance. * '''Comprehensive Experimental Protocol''' — preregistered prospective experiment discriminating a Penrose-style mass-geometry timescale from the BLQC capacity / instability timescale in the same mesoscopic apparatus. * '''Forensic Signatures''' — retrospective screening of Chinese 63-qubit, Google Sycamore, and LIGO data for the double-exponential visibility decay signature predicted by BLQC. Motivating evidence for treating LIGO as a candidate regime; not causal attribution. Detailed findings and caveats are discussed in [[#Open objections|Open objections]]. * '''The Capacity–Backaction Frontier''' — application to cryogenic quantum error correction.

A full archival deposit of the framework's documents is also available on the Open Science Framework at doi.org/10.17605/OSF.IO/FCDSN. == Open objections == The following objections to the framework are listed openly so that reviewers can engage with them directly. Several are diagnosed in the framework's own manuscripts; others reflect critiques the author has received in correspondence or anticipates from sophisticated readers. They are deliberately phrased from outside the framework's assumptions, not from within them. # '''Useful capacity versus thermodynamic bound'''. The framework uses the Landauer expression ''C'' ≤ ''P'' / (''k''<sub>B</sub> ''T'' ln 2) to relate controller input power ''P'' to channel capacity. Landauer is an ideal upper bound on bit-erasure cost; it does not guarantee that increased ''P'' actually translates to increased ''useful'' basis-tracking capacity. Additional power can equally well couple to actuator noise, electromagnetic leakage, vibration, or backaction channels that do not constrain the basis variable θ. Establishing that Δ''P'' → Δ''C''<sub>eff</sub> in the predicted direction — with realistic loss budgets for the candidate apparatus — is a substantive engineering claim that the framework does not by itself establish. # '''Existence of positive ''h''<sub>KS</sub> in engineered apparatus'''. Many precision controllers (phase-locked loops, qubit readout chains, interferometer servo systems) are explicitly engineered to suppress chaotic dynamics. The basis-defining degrees of freedom may exhibit colored noise, slow drift, or stochastic control error rather than positive-''h''<sub>KS</sub> chaos in the Pesin sense. If the relevant dynamics are not chaotic in this sense, the ''h''<sub>KS</sub> framing may not apply at all, and a different rate-distortion accounting (or none) would be needed. Even where positive ''h''<sub>KS</sub> can be identified, the operationally relevant rate may differ substantially from textbook surrogate estimates (kicked rotor, logistic map) used illustratively in the manuscripts. # '''Rate-distortion extension to nonlinear / chaotic systems'''. The mapping from channel capacity ''C'' to angular tracking variance σ<sub>θ</sub><sup>2</sup> ≥ ''D''/(''C'' ln 2) assumes a high-rate coder model and the framework extends the Data-Rate Theorem from linear plants to nonlinear chaotic systems by substituting ''h''<sub>KS</sub>. This extension is an explicit assumption, not a proven theorem. If the extension fails, the closed-form visibility law and the κ-regime structure both lose their derivation. # '''Gaussian small-angle assumption'''. The visibility expression ''V''(''t'') = exp(−½ σ<sub>θ</sub><sup>2</sup>) requires σ<sub>θ</sub> ≲ 1 rad and a Gaussian basis-tracking error distribution. Non-Gaussian, heavy-tailed, or state-dependent δθ would break the closed-form double-exponential law. # '''Decoherence and control-noise confound'''. Distinguishing the predicted visibility loss from ordinary environmental dephasing, alignment drift, and detector systematics is the central experimental challenge. The framework's answer is the sign-reversal under power variation at clamped ''T'' — a conceptually clean discriminator that is engineering-hard to realise. Independent calibration of ''C''<sub>eff</sub> may be the single largest practical hurdle. # '''Prior-art and reparameterization risk'''. The proposed double-exponential visibility signature may already be expressible within existing frameworks: compound dephasing channels with two or more contributing rates, classical feedback-loop instability, or hidden-variable control-noise models with appropriate parameter choices. The framework should be able to show that its prediction is genuinely new rather than a reparameterization of one of these known phenomena. The author's adversarial-mimic analysis is in progress, and a positive result on that front would substantially strengthen the framework's empirical claim. # '''Bell / locality consistency'''. The framework implies a structural violation of statistical measurement-independence. The author's response (common causal past plus global consistency, in place of fine-tuned initial conditions) is a philosophical reframing rather than a no-signalling lemma. A proper consistency proof has not been published. # '''Forensic-signature interpretation'''. The Forensic Signatures preprint applies a screening protocol to existing data from Chinese 63-qubit processors, Google Sycamore, and LIGO glitch records. The paper's own domain-of-validity statement is that BLQC applies in observer-limited rather than plant-limited regimes, and the protocol finds power-law dominance on the qubit datasets (consistent with that statement) and 43% Gompertz-consistent events on LIGO (consistent with BLQC). The paper flags a controller-regime confound for the LIGO result and is explicit that retrospective findings do not establish causal attribution to BLQC; the case rests on the prospective controlled-capacity experiment. The objection here is the standard one for retrospective signal analyses: even where the predicted geometry is present, it remains compatible with alternative explanations until the controlled experiment runs. # '''Observer language'''. The framework's "observer" plays two distinct roles: the physical apparatus / controller whose finite ''C''<sub>eff</sub> and ''h''<sub>KS</sub> appear in the equations, and the epistemic subject for whom measurement outcomes are or are not determinate. The framework treats these as connected but not identified, and the distinction is load-bearing. Critics will reasonably worry — especially given the framework's interpretive engagement with non-dual philosophy and the philosophy of mind — that consciousness is being smuggled into the foundations of measurement under physical vocabulary. The framework's defence is that the BLQC experimental claim is stated entirely in apparatus-level terms; whether that defence holds depends on the framework keeping the two senses of "observer" rigorously separate. # '''Interpretive vocabulary'''. Some of the framework's documents draw on vocabulary from philosophy of mind and non-dual philosophy (notably Advaita Vedānta) alongside the physical derivations. Readers who find this vocabulary off-putting are invited to evaluate the empirical content from the BLQC manuscript, which uses only standard physics and control-theory language. # '''Peer-review status and independent replication'''. The framework has not yet undergone peer review, and the experimental discriminator has not been independently replicated. This is the actual current epistemic status of the work. The framework's case must be evaluated on its merits in the documents linked above and on the conduct of the prospective experiment, not on any external imprimatur. == Invitation for review == This page is offered as a venue for substantive critique. The author is particularly interested in engagement on the following: * '''From physicists working on quantum control or precision interferometry''': is the proposed sign-reversal under controller-power variation at clamped temperature genuinely distinguishable from known instrumental artefacts (closed-loop resonances, thermal-noise mismodelling, photon-shot-noise rebalancing at higher gain), and what existing apparatus would be best positioned to perform the test? * '''From decoherence theorists''': under what conditions does the proposed double-exponential visibility law overlap with compound-channel decoherence models in ways that would make the two empirically indistinguishable? Is there a parameter regime where the framework's prediction is genuinely new rather than a reparameterisation of existing models? * '''From researchers in the foundations of quantum mechanics''': how should the framework's structural violation of measurement-independence be evaluated against the alternatives in the superdeterminism / retrocausality / many-worlds landscape, and what would constitute a satisfactory consistency proof? * '''From philosophers of mind''': the Advaita / RQM interpretive layer is offered conditionally on the empirical core. Is the conditional structure ("these readings are available ''if'' the empirical claim survives") presented clearly enough, or does it still amount to overreach? Comments, references to prior or parallel work the author may not be aware of, and pointers to potential confounds or alternative explanations are all welcome.

A Critical Response to Carlo Rovelli's "There Is No 'Hard Problem of Consciousness'"]'' (Dekker, May 2026). The response engages Rovelli's recent Noema essay, marks the substantial ground it shares with the framework, and identifies where the framework presses beyond Rovelli's deflationary physicalism toward a non-dual reading. Readers approaching the framework from philosophy of mind may find that essay the most accessible entry point. The framework's interpretive layer is developed in dialogue with two existing positions. The first is Carlo Rovelli's relational quantum mechanics. The framework can be read as supplying a candidate physical mechanism — the ''C''<sub>eff</sub> versus ''h''<sub>KS</sub> inequality — for what makes a measurement outcome relative to an observer rather than absolute. On this reading, the framework is a mechanistic specification of an idea that RQM leaves at the level of principle.

The framework's σ<sub>θ</sub><sup>2</sup>(''t'') — the growing basis-tracking error of an observer whose capacity is insufficient to track its own apparatus — admits a structural analogy with avidyā as the phenomenological self-opacity of an embodied subject. The framework neither asserts that this analogy is more than structural nor that any experimental result could confirm or refute Advaita as a philosophical position; it offers the analogy as a way of locating the framework within a non-dual reading of the measurement problem for readers who find that reading useful. Readers who prefer to ignore both interpretive readings should be able to evaluate the framework's empirical content from the [[#Technical proposal|Technical proposal]] and [[#Experimental discriminator|Experimental discriminator]] sections alone. A further speculative extension, ''[https://ignorantobserver.xyz/documents/Creation_of_Duality.pdf The Creation of Duality]'', asks whether space, time, objecthood, and gravity-like structure can themselves be read as features of a consistent finite-observer world-model, with a Bridge Ansatz ''E''<sub>G</sub> = (π/2)ℏκ linking the deficit rate κ to a gravitational energy scale via Margolus–Levitin saturation.

Several are diagnosed in the framework's own manuscripts; others reflect critiques the author has received in correspondence or anticipates from sophisticated readers. They are deliberately phrased from outside the framework's assumptions, not from within them. # '''Useful capacity versus thermodynamic bound'''. The framework uses the Landauer expression ''C'' ≤ ''P'' / (''k''<sub>B</sub> ''T'' ln 2) to relate controller input power ''P'' to channel capacity. Landauer is an ideal upper bound on bit-erasure cost; it does not guarantee that increased ''P'' actually translates to increased ''useful'' basis-tracking capacity. Additional power can equally well couple to actuator noise, electromagnetic leakage, vibration, or backaction channels that do not constrain the basis variable θ. Establishing that Δ''P'' → Δ''C''<sub>eff</sub> in the predicted direction — with realistic loss budgets for the candidate apparatus — is a substantive engineering claim that the framework does not by itself establish. # '''Existence of positive ''h''<sub>KS</sub> in engineered apparatus'''. Many precision controllers (phase-locked loops, qubit readout chains, interferometer servo systems) are explicitly engineered to suppress chaotic dynamics. The basis-defining degrees of freedom may exhibit colored noise, slow drift, or stochastic control error rather than positive-''h''<sub>KS</sub> chaos in the Pesin sense. If the relevant dynamics are not chaotic in this sense, the ''h''<sub>KS</sub> framing may not apply at all, and a different rate-distortion accounting (or none) would be needed. Even where positive ''h''<sub>KS</sub> can be identified, the operationally relevant rate may differ substantially from textbook surrogate estimates (kicked rotor, logistic map) used illustratively in the manuscripts. # '''Rate-distortion extension to nonlinear / chaotic systems'''. The mapping from channel capacity ''C'' to angular tracking variance σ<sub>θ</sub><sup>2</sup> ≥ ''D''/(''C'' ln 2) assumes a high-rate coder model and the framework extends the Data-Rate Theorem from linear plants to nonlinear chaotic systems by substituting ''h''<sub>KS</sub>. This extension is an explicit assumption, not a proven theorem. If the extension fails, the closed-form visibility law and the κ-regime structure both lose their derivation. # '''Gaussian small-angle assumption'''. The visibility expression ''V''(''t'') = exp(−½ σ<sub>θ</sub><sup>2</sup>) requires σ<sub>θ</sub> ≲ 1 rad and a Gaussian basis-tracking error distribution. Non-Gaussian, heavy-tailed, or state-dependent δθ would break the closed-form double-exponential law. # '''Decoherence and control-noise confound'''. Distinguishing the predicted visibility loss from ordinary environmental dephasing, alignment drift, and detector systematics is the central experimental challenge. The framework's answer is the sign-reversal under power variation at clamped ''T'' — a conceptually clean discriminator that is engineering-hard to realise. Independent calibration of ''C''<sub>eff</sub> may be the single largest practical hurdle. # '''Prior-art and reparameterization risk'''. The proposed double-exponential visibility signature may already be expressible within existing frameworks: compound dephasing channels with two or more contributing rates, classical feedback-loop instability, or hidden-variable control-noise models with appropriate parameter choices. The framework should be able to show that its prediction is genuinely new rather than a reparameterization of one of these known phenomena. The author's adversarial-mimic analysis is in progress, and a positive result on that front would substantially strengthen the framework's empirical claim. # '''Bell / locality consistency'''. The framework implies a structural violation of statistical measurement-independence. The author's response (common causal past plus global consistency, in place of fine-tuned initial conditions) is a philosophical reframing rather than a no-signalling lemma. A proper consistency proof has not been published. # '''Forensic-signature interpretation'''. The Forensic Signatures preprint applies a screening protocol to existing data from Chinese 63-qubit processors, Google Sycamore, and LIGO glitch records. The paper's own domain-of-validity statement is that BLQC applies in observer-limited rather than plant-limited regimes, and the protocol finds power-law dominance on the qubit datasets (consistent with that statement) and 43% Gompertz-consistent events on LIGO (consistent with BLQC). The paper flags a controller-regime confound for the LIGO result and is explicit that retrospective findings do not establish causal attribution to BLQC; the case rests on the prospective controlled-capacity experiment. The objection here is the standard one for retrospective signal analyses: even where the predicted geometry is present, it remains compatible with alternative explanations until the controlled experiment runs. # '''Observer language'''. The framework's "observer" plays two distinct roles: the physical apparatus / controller whose finite ''C''<sub>eff</sub> and ''h''<sub>KS</sub> appear in the equations, and the epistemic subject for whom measurement outcomes are or are not determinate. The framework treats these as connected but not identified, and the distinction is load-bearing. Critics will reasonably worry — especially given the framework's interpretive engagement with non-dual philosophy and the philosophy of mind — that consciousness is being smuggled into the foundations of measurement under physical vocabulary. The framework's defence is that the BLQC experimental claim is stated entirely in apparatus-level terms; whether that defence holds depends on the framework keeping the two senses of "observer" rigorously separate. # '''Interpretive vocabulary'''. Some of the framework's documents draw on vocabulary from philosophy of mind and non-dual philosophy (notably Advaita Vedānta) alongside the physical derivations. Readers who find this vocabulary off-putting are invited to evaluate the empirical content from the BLQC manuscript, which uses only standard physics and control-theory language. # '''Peer-review status and independent replication'''. The framework has not yet undergone peer review, and the experimental discriminator has not been independently replicated. This is the actual current epistemic status of the work. The framework's case must be evaluated on its merits in the documents linked above and on the conduct of the prospective experiment, not on any external imprimatur. == Invitation for review == This page is offered as a venue for substantive critique. The author is particularly interested in engagement on the following: * '''From physicists working on quantum control or precision interferometry''': is the proposed sign-reversal under controller-power variation at clamped temperature genuinely distinguishable from known instrumental artefacts (closed-loop resonances, thermal-noise mismodelling, photon-shot-noise rebalancing at higher gain), and what existing apparatus would be best positioned to perform the test? * '''From decoherence theorists''': under what conditions does the proposed double-exponential visibility law overlap with compound-channel decoherence models in ways that would make the two empirically indistinguishable? Is there a parameter regime where the framework's prediction is genuinely new rather than a reparameterisation of existing models? * '''From researchers in the foundations of quantum mechanics''': how should the framework's structural violation of measurement-independence be evaluated against the alternatives in the superdeterminism / retrocausality / many-worlds landscape, and what would constitute a satisfactory consistency proof? * '''From philosophers of mind''': the Advaita / RQM interpretive layer is offered conditionally on the empirical core. Is the conditional structure ("these readings are available ''if'' the empirical claim survives") presented clearly enough, or does it still amount to overreach? Comments, references to prior or parallel work the author may not be aware of, and pointers to potential confounds or alternative explanations are all welcome. Substantive critique on the [[User talk:IgnorantObserver/sandbox|talk page]] will be acknowledged in subsequent revisions of the manuscripts. == References == * Brukner, Č., & Zeilinger, A. (1999).

Page text is offered for review, critique, and collaborative refinement under [[Wikiversity:Copyrights|Wikiversity's standard licence]].'' == Status == Research project under active development. The framework consists of an interlinked set of technical and interpretive documents published at [https://ignorantobserver.xyz ignorantobserver.xyz] and archived on the [https://osf.io Open Science Framework]. The technical module ''Bandwidth-Limited Quantum Control'' (BLQC) sets out the framework's falsifiable experimental discriminator. The broader ''Ignorant Observer Framework'' (IOF) connects this technical core to questions in the foundations of quantum mechanics and the philosophy of mind. All work is single-authored. == Summary == The Ignorant Observer Framework proposes that the conventional treatment of quantum measurement idealizes the measurement basis as stably available to the observer. The framework removes that idealization. It treats the measurement basis θ as a physical dynamical variable inside the apparatus, with its own causal history and its own information-production rate. Whether the apparatus can stably track θ is then a control-theoretic question, governed by an inequality between effective information-channel capacity and the basis-defining dynamics' entropy rate. ''Bandwidth-Limited Quantum Control'' (BLQC), the framework's technical module, derives — under the assumptions catalogued in the [[#Open objections|Open objections]] section below — a distinctive ''double-exponential'' visibility decay law and a corresponding falsifiable experimental signature: under variation of controller input power at clamped environmental temperature, the framework predicts that coherence time should ''lengthen'' with increasing power, the opposite of standard thermal decoherence. This sign-reversal is the central testable claim. The framework as a whole also offers an interpretive extension that connects the technical proposal to existing positions in quantum foundations (Brukner, Rovelli's relational quantum mechanics) and to non-dual philosophy of mind (Advaita Vedānta). These interpretive elements are clearly fenced from the empirical core in [[#Philosophical interpretation|the relevant section below]]. What stands or falls with the experimental discriminator is the framework's specific physical mapping into these positions, not the positions themselves. == Core question == ''Can quantum visibility depend on finite observer or apparatus basis-tracking capacity, independently of, and distinguishably from, ordinary environmental decoherence?'' Phrased positively: if the classical degrees of freedom that define and maintain a measurement basis exhibit chaotic dynamics with positive Kolmogorov–Sinai entropy rate ''h''<sub>KS</sub>, and if the effective information channel that constrains those degrees of freedom has capacity ''C''<sub>eff</sub> insufficient to track them, does interference visibility decay in a functional form distinguishable from standard exponential or Gaussian dephasing — and does this decay respond to controller input power in a direction opposite to thermal decoherence? == Technical proposal == The framework introduces the following quantities. '''Effective channel capacity ''C''<sub>eff</sub>''' (bits/s): the information rate available to the basis-tracking control loop, operationalised as :''C''<sub>eff</sub> = ''r'' · ''b'' · ''f'' with ''r'' the update rate (Hz), ''b'' the effective number of bits per update that constrain the basis variable θ, and ''f'' ∈ (0,1] the fraction of updates that genuinely constrain θ after overhead and latency. ''C''<sub>eff</sub> is bounded above by the Landauer limit on the controller's actuation: :''C''<sub>eff</sub> ≤ ''P'' / (''k''<sub>B</sub> ''T'' ln 2) where ''P'' is controller input power and ''T'' is the temperature at which the controller operates. '''Kolmogorov–Sinai entropy rate ''h''<sub>KS</sub>''' (nats/s): the information-production rate of the classical degrees of freedom (voltage references, timing circuits, feedback loops) that define and maintain the measurement basis. For chaotic systems, ''h''<sub>KS</sub> equals the sum of positive Lyapunov exponents (Pesin identity). It is estimated operationally from the exponential growth of one-step prediction error on logged controller states. The nats/s convention is used so that the deficit κ below combines ''h''<sub>KS</sub> (nats/s) and ''C''<sub>eff</sub> ln 2 (bits/s converted to nats/s) in consistent units; an equivalent all-bits form would be κ<sub>bits</sub> = ''h''<sub>KS,bits</sub> − ''C''<sub>eff</sub>. '''Ignorance rate κ''' (s<sup>−1</sup>): :κ = ''h''<sub>KS</sub> − ''C''<sub>eff</sub> · ln 2 The framework distinguishes two regimes. When κ < 0 (''capacity-wins''), basis-tracking error stays bounded and standard quantum mechanics is recovered. When κ > 0 (''chaos-wins''), the variance of the basis-tracking error grows exponentially in time as σ<sub>θ</sub><sup>2</sup>(''t'') = σ<sub>0</sub><sup>2</sup> e<sup>2κ''t''</sup>. '''Measured visibility ''V''(''t'')'''. Averaging the interference term cos(φ − θ) over a Gaussian distribution of basis-tracking error δθ ∼ ''N''(0, σ<sub>θ</sub><sup>2</sup>(''t'')) yields, in the small-angle regime, :''V''(''t'') = exp(−½ σ<sub>0</sub><sup>2</sup> e<sup>2κ''t''</sup>) i.e. a ''double-exponential'' decay of visibility once the chaos-wins regime is entered. '''Breakdown time ''t''<sub>break</sub>'''. For a chosen visibility threshold ''V''*, :''t''<sub>break</sub> = (1 / 2κ) · ln(−2 ln ''V''* / σ<sub>0</sub><sup>2</sup>) for κ > 0. ''t''<sub>break</sub> is the framework's primary observable. The technical derivation extends the Data-Rate Theorem of Nair & Evans (2004) and Tatikonda & Mitter (2004) from linear plants to nonlinear, chaotic systems by substituting ''h''<sub>KS</sub> for the sum-of-positive-eigenvalues bound. This extension is an explicit assumption of the framework rather than a proven theorem (see [[#Open objections|Open objections]]). == Experimental discriminator == The framework prescribes the following experimental protocol as its central falsifiable test. '''Independent variable''': controller input power ''P''. The controller is the physical system whose state defines and maintains the measurement basis (e.g. an interferometer phase-locking loop, a qubit readout chain, the active feedback in a precision interferometer). '''Held constant''': the environmental temperature ''T'' at which the controller operates, by independent active thermal feedback. Holding ''T'' constant while varying ''P'' is what distinguishes the framework's prediction from standard thermal decoherence (which depends on ''T'' and ignores ''P''). '''Dependent variable''': the visibility-decay breakdown time ''t''<sub>break</sub>, fitted to interference data at a chosen visibility threshold (e.g. ''V''* = 0.5). '''Prediction''': ∂''t''<sub>break</sub>/∂''P'' > 0 at clamped ''T'', with the visibility curve ''V''(''t'') fitting the double-exponential form exp(−½ σ<sub>0</sub><sup>2</sup> e<sup>2κ''t''</sup>) better than a standard exponential ''e''<sup>−Γ''t''</sup> or Gaussian ''e''<sup>−γ''t''²</sup>. '''What would count as falsification'''. Any of the following null findings counts against the framework: * ∂''t''<sub>break</sub>/∂''P'' ≤ 0 at clamped ''T'' (i.e. increasing controller power does not extend, or shortens, coherence time); * ''V''(''t'') fits a single-exponential or Gaussian dephasing law significantly better than the double-exponential form, in the regime where the framework predicts the double-exponential should dominate; * ''t''<sub>break</sub> scales with the gravitational self-energy timescale ''t''<sub>OR</sub> ∝ ''s'' / ''m''<sup>2</sup> (the [[Penrose interpretation of quantum mechanics|Penrose Objective Reduction]] prediction) rather than with ''C''<sub>eff</sub>; * ''C''<sub>eff</sub> cannot be calibrated independently of ''t''<sub>break</sub> (in which case the prediction would be unfalsifiable, which would itself count against the framework's experimental status). The [https://www.qgemproject.com/ QGEM] pathfinder is cited in the BLQC manuscript as one candidate testbed; superconducting-qubit readout chains and precision interferometer phase-locking loops are others. == Relation to quantum foundations == The framework is connected to, and partly draws from, several existing positions in the foundations of quantum mechanics. * '''Brukner's information-theoretic reconstructions''' provide a precedent for treating information limits as structural constraints in quantum theory. * '''Relational Quantum Mechanics''' (Rovelli) takes measurement outcomes to be relative to an observer-system; the framework provides one possible mechanism (finite ''C''<sub>eff</sub>) for what makes one observer's frame physically inequivalent to another's. * '''Decoherence theory''' is not opposed by the framework. The framework's prediction sits beside ordinary environmental decoherence and is intended to be ''distinguishable'' from it by the sign-reversal under power variation; in the capacity-wins regime (κ < 0) standard decoherence theory is recovered. * '''Measurement-independence'''. Because the framework treats the measurement basis as a dynamical variable with its own causal history, if extended to Bell-type set-ups it appears to imply a structural violation of statistical measurement-independence. The framework's response to the conventional "conspiracy" objection against superdeterminism is to attribute the correlation to common causal past plus a global consistency constraint rather than to fine-tuned initial conditions. This response is philosophical rather than mathematical and the formal extension (including a no-signalling treatment) is itself an open question (see [[#Open objections|Open objections]]). * '''Penrose Objective Reduction''' is treated as an ''orthogonal'' competing mechanism whose predicted ''t''<sub>OR</sub> ∝ ''s'' / ''m''<sup>2</sup> scaling can be experimentally distinguished from the framework's ''C''<sub>eff</sub>-driven ''t''<sub>break</sub>. The numerical proximity of the two timescales in the mesoscopic regime motivates the protocol described in the next section but is treated as a coincidence pending experimental evidence. == Philosophical interpretation == ''This section describes interpretive extensions of the framework that go beyond the empirical core. Nothing in this section is a load-bearing element of the experimental claim. If the experimental discriminator returns a null result, the claimed physical realization of these interpretive readings within the framework would fall. The interpretive positions themselves — Advaita Vedānta, relational quantum mechanics — do not stand or fall on an interferometry experiment; what stands or falls is the framework's specific physical mapping into them.'' A direct statement of the framework's interpretive position appears in ''[https://ignorantobserver.xyz/documents/Hard_Problem_After_Deflation.pdf The Hard Problem Dissolved — But Into What? A Critical Response to Carlo Rovelli's "There Is No 'Hard Problem of Consciousness'"]'' (Dekker, May 2026). The response engages Rovelli's recent Noema essay, marks the substantial ground it shares with the framework, and identifies where the framework presses beyond Rovelli's deflationary physicalism toward a non-dual reading. Readers approaching the framework from philosophy of mind may find that essay the most accessible entry point. The framework's interpretive layer is developed in dialogue with two existing positions. The first is Carlo Rovelli's relational quantum mechanics. The framework can be read as supplying a candidate physical mechanism — the ''C''<sub>eff</sub> versus ''h''<sub>KS</sub> inequality — for what makes a measurement outcome relative to an observer rather than absolute.

The second is the Advaita Vedānta tradition (Śaṅkara, Ramaṇa Mahaṛṣi), in which the apparent independence of the experiencing subject from the perceived world is treated as a structural feature of ignorance (''avidyā'') rather than a metaphysical fact. The framework's σ<sub>θ</sub><sup>2</sup>(''t'') — the growing basis-tracking error of an observer whose capacity is insufficient to track its own apparatus — admits a structural analogy with avidyā as the phenomenological self-opacity of an embodied subject.

Readers who prefer to ignore both interpretive readings should be able to evaluate the framework's empirical content from the [[#Technical proposal|Technical proposal]] and [[#Experimental discriminator|Experimental discriminator]] sections alone. A further speculative extension, ''[https://ignorantobserver.xyz/documents/Creation_of_Duality.pdf The Creation of Duality]'', asks whether space, time, objecthood, and gravity-like structure can themselves be read as features of a consistent finite-observer world-model, with a Bridge Ansatz ''E''<sub>G</sub> = (π/2)ℏκ linking the deficit rate κ to a gravitational energy scale via Margolus–Levitin saturation.

The paper's own domain-of-validity statement is that BLQC applies in observer-limited rather than plant-limited regimes, and the protocol finds power-law dominance on the qubit datasets (consistent with that statement) and 43% Gompertz-consistent events on LIGO (consistent with BLQC). The paper flags a controller-regime confound for the LIGO result and is explicit that retrospective findings do not establish causal attribution to BLQC; the case rests on the prospective controlled-capacity experiment. The objection here is the standard one for retrospective signal analyses: even where the predicted geometry is present, it remains compatible with alternative explanations until the controlled experiment runs. # '''Observer language'''. The framework's "observer" plays two distinct roles: the physical apparatus / controller whose finite ''C''<sub>eff</sub> and ''h''<sub>KS</sub> appear in the equations, and the epistemic subject for whom measurement outcomes are or are not determinate. The framework treats these as connected but not identified, and the distinction is load-bearing. Critics will reasonably worry — especially given the framework's interpretive engagement with non-dual philosophy and the philosophy of mind — that consciousness is being smuggled into the foundations of measurement under physical vocabulary. The framework's defence is that the BLQC experimental claim is stated entirely in apparatus-level terms; whether that defence holds depends on the framework keeping the two senses of "observer" rigorously separate. # '''Interpretive vocabulary'''. Some of the framework's documents draw on vocabulary from philosophy of mind and non-dual philosophy (notably Advaita Vedānta) alongside the physical derivations. Readers who find this vocabulary off-putting are invited to evaluate the empirical content from the BLQC manuscript, which uses only standard physics and control-theory language. # '''Peer-review status and independent replication'''. The framework has not yet undergone peer review, and the experimental discriminator has not been independently replicated. This is the actual current epistemic status of the work. The framework's case must be evaluated on its merits in the documents linked above and on the conduct of the prospective experiment, not on any external imprimatur. == Invitation for review == This page is offered as a venue for substantive critique. The author is particularly interested in engagement on the following: * '''From physicists working on quantum control or precision interferometry''': is the proposed sign-reversal under controller-power variation at clamped temperature genuinely distinguishable from known instrumental artefacts (closed-loop resonances, thermal-noise mismodelling, photon-shot-noise rebalancing at higher gain), and what existing apparatus would be best positioned to perform the test? * '''From decoherence theorists''': under what conditions does the proposed double-exponential visibility law overlap with compound-channel decoherence models in ways that would make the two empirically indistinguishable? Is there a parameter regime where the framework's prediction is genuinely new rather than a reparameterisation of existing models? * '''From researchers in the foundations of quantum mechanics''': how should the framework's structural violation of measurement-independence be evaluated against the alternatives in the superdeterminism / retrocausality / many-worlds landscape, and what would constitute a satisfactory consistency proof? * '''From philosophers of mind''': the Advaita / RQM interpretive layer is offered conditionally on the empirical core. Is the conditional structure ("these readings are available ''if'' the empirical claim survives") presented clearly enough, or does it still amount to overreach?

Page text is offered for review, critique, and collaborative refinement under [[Wikiversity:Copyrights|Wikiversity's standard licence]].'' == Status == Research project under active development. The framework consists of an interlinked set of technical and interpretive documents published at ignorantobserver.xyz and archived on the Open Science Framework. The technical module ''Bandwidth-Limited Quantum Control'' (BLQC) sets out the framework's falsifiable experimental discriminator. The broader ''Ignorant Observer Framework'' (IOF) connects this technical core to questions in the foundations of quantum mechanics and the philosophy of mind. All work is single-authored. == Summary == The Ignorant Observer Framework proposes that the conventional treatment of quantum measurement idealizes the measurement basis as stably available to the observer. The framework removes that idealization. It treats the measurement basis θ as a physical dynamical variable inside the apparatus, with its own causal history and its own information-production rate. Whether the apparatus can stably track θ is then a control-theoretic question, governed by an inequality between effective information-channel capacity and the basis-defining dynamics' entropy rate. ''Bandwidth-Limited Quantum Control'' (BLQC), the framework's technical module, derives — under the assumptions catalogued in the [[#Open objections|Open objections]] section below — a distinctive ''double-exponential'' visibility decay law and a corresponding falsifiable experimental signature: under variation of controller input power at clamped environmental temperature, the framework predicts that coherence time should ''lengthen'' with increasing power, the opposite of standard thermal decoherence. This sign-reversal is the central testable claim. The framework as a whole also offers an interpretive extension that connects the technical proposal to existing positions in quantum foundations (Brukner, Rovelli's relational quantum mechanics) and to non-dual philosophy of mind (Advaita Vedānta). These interpretive elements are clearly fenced from the empirical core in [[#Philosophical interpretation|the relevant section below]]. What stands or falls with the experimental discriminator is the framework's specific physical mapping into these positions, not the positions themselves. == Core question == ''Can quantum visibility depend on finite observer or apparatus basis-tracking capacity, independently of, and distinguishably from, ordinary environmental decoherence?'' Phrased positively: if the classical degrees of freedom that define and maintain a measurement basis exhibit chaotic dynamics with positive Kolmogorov–Sinai entropy rate ''h''<sub>KS</sub>, and if the effective information channel that constrains those degrees of freedom has capacity ''C''<sub>eff</sub> insufficient to track them, does interference visibility decay in a functional form distinguishable from standard exponential or Gaussian dephasing — and does this decay respond to controller input power in a direction opposite to thermal decoherence? == Technical proposal == The framework introduces the following quantities. '''Effective channel capacity ''C''<sub>eff</sub>''' (bits/s): the information rate available to the basis-tracking control loop, operationalised as :''C''<sub>eff</sub> = ''r'' · ''b'' · ''f'' with ''r'' the update rate (Hz), ''b'' the effective number of bits per update that constrain the basis variable θ, and ''f'' ∈ (0,1] the fraction of updates that genuinely constrain θ after overhead and latency. ''C''<sub>eff</sub> is bounded above by the Landauer limit on the controller's actuation: :''C''<sub>eff</sub> ≤ ''P'' / (''k''<sub>B</sub> ''T'' ln 2) where ''P'' is controller input power and ''T'' is the temperature at which the controller operates. '''Kolmogorov–Sinai entropy rate ''h''<sub>KS</sub>''' (nats/s): the information-production rate of the classical degrees of freedom (voltage references, timing circuits, feedback loops) that define and maintain the measurement basis. For chaotic systems, ''h''<sub>KS</sub> equals the sum of positive Lyapunov exponents (Pesin identity). It is estimated operationally from the exponential growth of one-step prediction error on logged controller states. The nats/s convention is used so that the deficit κ below combines ''h''<sub>KS</sub> (nats/s) and ''C''<sub>eff</sub> ln 2 (bits/s converted to nats/s) in consistent units; an equivalent all-bits form would be κ<sub>bits</sub> = ''h''<sub>KS,bits</sub> − ''C''<sub>eff</sub>. '''Ignorance rate κ''' (s<sup>−1</sup>): :κ = ''h''<sub>KS</sub> − ''C''<sub>eff</sub> · ln 2 The framework distinguishes two regimes. When κ < 0 (''capacity-wins''), basis-tracking error stays bounded and standard quantum mechanics is recovered. When κ > 0 (''chaos-wins''), the variance of the basis-tracking error grows exponentially in time as σ<sub>θ</sub><sup>2</sup>(''t'') = σ<sub>0</sub><sup>2</sup> e<sup>2κ''t''</sup>. '''Measured visibility ''V''(''t'')'''. Averaging the interference term cos(φ − θ) over a Gaussian distribution of basis-tracking error δθ ∼ ''N''(0, σ<sub>θ</sub><sup>2</sup>(''t'')) yields, in the small-angle regime, :''V''(''t'') = exp(−½ σ<sub>0</sub><sup>2</sup> e<sup>2κ''t''</sup>) i.e. a ''double-exponential'' decay of visibility once the chaos-wins regime is entered. '''Breakdown time ''t''<sub>break</sub>'''. For a chosen visibility threshold ''V''*, :''t''<sub>break</sub> = (1 / 2κ) · ln(−2 ln ''V''* / σ<sub>0</sub><sup>2</sup>) for κ > 0. ''t''<sub>break</sub> is the framework's primary observable. The technical derivation extends the Data-Rate Theorem of Nair & Evans (2004) and Tatikonda & Mitter (2004) from linear plants to nonlinear, chaotic systems by substituting ''h''<sub>KS</sub> for the sum-of-positive-eigenvalues bound. This extension is an explicit assumption of the framework rather than a proven theorem (see [[#Open objections|Open objections]]). == Experimental discriminator == The framework prescribes the following experimental protocol as its central falsifiable test. '''Independent variable''': controller input power ''P''. The controller is the physical system whose state defines and maintains the measurement basis (e.g. an interferometer phase-locking loop, a qubit readout chain, the active feedback in a precision interferometer). '''Held constant''': the environmental temperature ''T'' at which the controller operates, by independent active thermal feedback. Holding ''T'' constant while varying ''P'' is what distinguishes the framework's prediction from standard thermal decoherence (which depends on ''T'' and ignores ''P''). '''Dependent variable''': the visibility-decay breakdown time ''t''<sub>break</sub>, fitted to interference data at a chosen visibility threshold (e.g. ''V''* = 0.5). '''Prediction''': ∂''t''<sub>break</sub>/∂''P'' > 0 at clamped ''T'', with the visibility curve ''V''(''t'') fitting the double-exponential form exp(−½ σ<sub>0</sub><sup>2</sup> e<sup>2κ''t''</sup>) better than a standard exponential ''e''<sup>−Γ''t''</sup> or Gaussian ''e''<sup>−γ''t''²</sup>. '''What would count as falsification'''. Any of the following null findings counts against the framework: * ∂''t''<sub>break</sub>/∂''P'' ≤ 0 at clamped ''T'' (i.e. increasing controller power does not extend, or shortens, coherence time); * ''V''(''t'') fits a single-exponential or Gaussian dephasing law significantly better than the double-exponential form, in the regime where the framework predicts the double-exponential should dominate; * ''t''<sub>break</sub> scales with the gravitational self-energy timescale ''t''<sub>OR</sub> ∝ ''s'' / ''m''<sup>2</sup> (the [[Penrose interpretation of quantum mechanics|Penrose Objective Reduction]] prediction) rather than with ''C''<sub>eff</sub>; * ''C''<sub>eff</sub> cannot be calibrated independently of ''t''<sub>break</sub> (in which case the prediction would be unfalsifiable, which would itself count against the framework's experimental status). The QGEM pathfinder is cited in the BLQC manuscript as one candidate testbed; superconducting-qubit readout chains and precision interferometer phase-locking loops are others. == Relation to quantum foundations == The framework is connected to, and partly draws from, several existing positions in the foundations of quantum mechanics. * '''Brukner's information-theoretic reconstructions''' provide a precedent for treating information limits as structural constraints in quantum theory. * '''Relational Quantum Mechanics''' (Rovelli) takes measurement outcomes to be relative to an observer-system; the framework provides one possible mechanism (finite ''C''<sub>eff</sub>) for what makes one observer's frame physically inequivalent to another's. * '''Decoherence theory''' is not opposed by the framework. The framework's prediction sits beside ordinary environmental decoherence and is intended to be ''distinguishable'' from it by the sign-reversal under power variation; in the capacity-wins regime (κ < 0) standard decoherence theory is recovered. * '''Measurement-independence'''. Because the framework treats the measurement basis as a dynamical variable with its own causal history, if extended to Bell-type set-ups it appears to imply a structural violation of statistical measurement-independence. The framework's response to the conventional "conspiracy" objection against superdeterminism is to attribute the correlation to common causal past plus a global consistency constraint rather than to fine-tuned initial conditions. This response is philosophical rather than mathematical and the formal extension (including a no-signalling treatment) is itself an open question (see [[#Open objections|Open objections]]). * '''Penrose Objective Reduction''' is treated as an ''orthogonal'' competing mechanism whose predicted ''t''<sub>OR</sub> ∝ ''s'' / ''m''<sup>2</sup> scaling can be experimentally distinguished from the framework's ''C''<sub>eff</sub>-driven ''t''<sub>break</sub>. The numerical proximity of the two timescales in the mesoscopic regime motivates the protocol described in the next section but is treated as a coincidence pending experimental evidence. == Philosophical interpretation == ''This section describes interpretive extensions of the framework that go beyond the empirical core. Nothing in this section is a load-bearing element of the experimental claim. If the experimental discriminator returns a null result, the claimed physical realization of these interpretive readings within the framework would fall. The interpretive positions themselves — Advaita Vedānta, relational quantum mechanics — do not stand or fall on an interferometry experiment; what stands or falls is the framework's specific physical mapping into them.'' A direct statement of the framework's interpretive position appears in ''The Hard Problem Dissolved — But Into What? A Critical Response to Carlo Rovelli's "There Is No 'Hard Problem of Consciousness'"'' (Dekker, May 2026). The response engages Rovelli's recent Noema essay, marks the substantial ground it shares with the framework, and identifies where the framework presses beyond Rovelli's deflationary physicalism toward a non-dual reading. Readers approaching the framework from philosophy of mind may find that essay the most accessible entry point. The framework's interpretive layer is developed in dialogue with two existing positions. The first is Carlo Rovelli's relational quantum mechanics. The framework can be read as supplying a candidate physical mechanism — the ''C''<sub>eff</sub> versus ''h''<sub>KS</sub> inequality — for what makes a measurement outcome relative to an observer rather than absolute. On this reading, the framework is a mechanistic specification of an idea that RQM leaves at the level of principle. The second is the Advaita Vedānta tradition (Śaṅkara, Ramaṇa Mahaṛṣi), in which the apparent independence of the experiencing subject from the perceived world is treated as a structural feature of ignorance (''avidyā'') rather than a metaphysical fact. The framework's σ<sub>θ</sub><sup>2</sup>(''t'') — the growing basis-tracking error of an observer whose capacity is insufficient to track its own apparatus — admits a structural analogy with avidyā as the phenomenological self-opacity of an embodied subject. The framework neither asserts that this analogy is more than structural nor that any experimental result could confirm or refute Advaita as a philosophical position; it offers the analogy as a way of locating the framework within a non-dual reading of the measurement problem for readers who find that reading useful. Readers who prefer to ignore both interpretive readings should be able to evaluate the framework's empirical content from the [[#Technical proposal|Technical proposal]] and [[#Experimental discriminator|Experimental discriminator]] sections alone. A further speculative extension, ''The Creation of Duality'', asks whether space, time, objecthood, and gravity-like structure can themselves be read as features of a consistent finite-observer world-model, with a Bridge Ansatz ''E''<sub>G</sub> = (π/2)ℏκ linking the deficit rate κ to a gravitational energy scale via Margolus–Levitin saturation. Its scientific status is contingent on the BLQC experimental discriminator; until then it is offered explicitly as speculation. == Documents == The framework's documents are published at ignorantobserver.xyz. Direct links to the principal documents: * '''Bandwidth-Limited Quantum Control''' — finite-rate phase-reference test in the Penrose-overlap regime. The framework's falsifiable experimental discriminator. * '''The Ignorant Observer''' — main framework document. Physical formalization inspired by Advaita Vedanta's insight into ignorance. * '''Comprehensive Experimental Protocol''' — preregistered prospective experiment discriminating a Penrose-style mass-geometry timescale from the BLQC capacity / instability timescale in the same mesoscopic apparatus. * '''Forensic Signatures''' — retrospective screening of Chinese 63-qubit, Google Sycamore, and LIGO data for the double-exponential visibility decay signature predicted by BLQC. Motivating evidence for treating LIGO as a candidate regime; not causal attribution. Detailed findings and caveats are discussed in [[#Open objections|Open objections]]. * '''The Capacity–Backaction Frontier''' — application to cryogenic quantum error correction.

A full archival deposit of the framework's documents is also available on the Open Science Framework at doi.org/10.17605/OSF.IO/FCDSN. == Open objections == The following objections to the framework are listed openly so that reviewers can engage with them directly. Several are diagnosed in the framework's own manuscripts; others reflect critiques the author has received in correspondence or anticipates from sophisticated readers. They are deliberately phrased from outside the framework's assumptions, not from within them. # '''Useful capacity versus thermodynamic bound'''. The framework uses the Landauer expression ''C'' ≤ ''P'' / (''k''<sub>B</sub> ''T'' ln 2) to relate controller input power ''P'' to channel capacity. Landauer is an ideal upper bound on bit-erasure cost; it does not guarantee that increased ''P'' actually translates to increased ''useful'' basis-tracking capacity. Additional power can equally well couple to actuator noise, electromagnetic leakage, vibration, or backaction channels that do not constrain the basis variable θ. Establishing that Δ''P'' → Δ''C''<sub>eff</sub> in the predicted direction — with realistic loss budgets for the candidate apparatus — is a substantive engineering claim that the framework does not by itself establish. # '''Existence of positive ''h''<sub>KS</sub> in engineered apparatus'''. Many precision controllers (phase-locked loops, qubit readout chains, interferometer servo systems) are explicitly engineered to suppress chaotic dynamics. The basis-defining degrees of freedom may exhibit colored noise, slow drift, or stochastic control error rather than positive-''h''<sub>KS</sub> chaos in the Pesin sense. If the relevant dynamics are not chaotic in this sense, the ''h''<sub>KS</sub> framing may not apply at all, and a different rate-distortion accounting (or none) would be needed. Even where positive ''h''<sub>KS</sub> can be identified, the operationally relevant rate may differ substantially from textbook surrogate estimates (kicked rotor, logistic map) used illustratively in the manuscripts. # '''Rate-distortion extension to nonlinear / chaotic systems'''. The mapping from channel capacity ''C'' to angular tracking variance σ<sub>θ</sub><sup>2</sup> ≥ ''D''/(''C'' ln 2) assumes a high-rate coder model and the framework extends the Data-Rate Theorem from linear plants to nonlinear chaotic systems by substituting ''h''<sub>KS</sub>. This extension is an explicit assumption, not a proven theorem. If the extension fails, the closed-form visibility law and the κ-regime structure both lose their derivation. # '''Gaussian small-angle assumption'''. The visibility expression ''V''(''t'') = exp(−½ σ<sub>θ</sub><sup>2</sup>) requires σ<sub>θ</sub> ≲ 1 rad and a Gaussian basis-tracking error distribution. Non-Gaussian, heavy-tailed, or state-dependent δθ would break the closed-form double-exponential law. # '''Decoherence and control-noise confound'''. Distinguishing the predicted visibility loss from ordinary environmental dephasing, alignment drift, and detector systematics is the central experimental challenge. The framework's answer is the sign-reversal under power variation at clamped ''T'' — a conceptually clean discriminator that is engineering-hard to realise. Independent calibration of ''C''<sub>eff</sub> may be the single largest practical hurdle. # '''Prior-art and reparameterization risk'''. The proposed double-exponential visibility signature may already be expressible within existing frameworks: compound dephasing channels with two or more contributing rates, classical feedback-loop instability, or hidden-variable control-noise models with appropriate parameter choices. The framework should be able to show that its prediction is genuinely new rather than a reparameterization of one of these known phenomena. The author's adversarial-mimic analysis is in progress, and a positive result on that front would substantially strengthen the framework's empirical claim. # '''Bell / locality consistency'''. The framework implies a structural violation of statistical measurement-independence. The author's response (common causal past plus global consistency, in place of fine-tuned initial conditions) is a philosophical reframing rather than a no-signalling lemma. A proper consistency proof has not been published. # '''Forensic-signature interpretation'''. The Forensic Signatures preprint applies a screening protocol to existing data from Chinese 63-qubit processors, Google Sycamore, and LIGO glitch records. The paper's own domain-of-validity statement is that BLQC applies in observer-limited rather than plant-limited regimes, and the protocol finds power-law dominance on the qubit datasets (consistent with that statement) and 43% Gompertz-consistent events on LIGO (consistent with BLQC). The paper flags a controller-regime confound for the LIGO result and is explicit that retrospective findings do not establish causal attribution to BLQC; the case rests on the prospective controlled-capacity experiment. The objection here is the standard one for retrospective signal analyses: even where the predicted geometry is present, it remains compatible with alternative explanations until the controlled experiment runs. # '''Observer language'''. The framework's "observer" plays two distinct roles: the physical apparatus / controller whose finite ''C''<sub>eff</sub> and ''h''<sub>KS</sub> appear in the equations, and the epistemic subject for whom measurement outcomes are or are not determinate. The framework treats these as connected but not identified, and the distinction is load-bearing. Critics will reasonably worry — especially given the framework's interpretive engagement with non-dual philosophy and the philosophy of mind — that consciousness is being smuggled into the foundations of measurement under physical vocabulary. The framework's defence is that the BLQC experimental claim is stated entirely in apparatus-level terms; whether that defence holds depends on the framework keeping the two senses of "observer" rigorously separate. # '''Interpretive vocabulary'''. Some of the framework's documents draw on vocabulary from philosophy of mind and non-dual philosophy (notably Advaita Vedānta) alongside the physical derivations. Readers who find this vocabulary off-putting are invited to evaluate the empirical content from the BLQC manuscript, which uses only standard physics and control-theory language. # '''Peer-review status and independent replication'''. The framework has not yet undergone peer review, and the experimental discriminator has not been independently replicated. This is the actual current epistemic status of the work. The framework's case must be evaluated on its merits in the documents linked above and on the conduct of the prospective experiment, not on any external imprimatur. == Invitation for review == This page is offered as a venue for substantive critique.

'''Breakdown time ''t''<sub>break</sub>'''. For a chosen visibility threshold ''V''*, :''t''<sub>break</sub> = (1 / 2κ) · ln(−2 ln ''V''* / σ<sub>0</sub><sup>2</sup>) for κ > 0. ''t''<sub>break</sub> is the framework's primary observable. The technical derivation extends the Data-Rate Theorem of Nair & Evans (2004) and Tatikonda & Mitter (2004) from linear plants to nonlinear, chaotic systems by substituting ''h''<sub>KS</sub> for the sum-of-positive-eigenvalues bound. This extension is an explicit assumption of the framework rather than a proven theorem (see [[#Open objections|Open objections]]). == Experimental discriminator == The framework prescribes the following experimental protocol as its central falsifiable test. '''Independent variable''': controller input power ''P''. The controller is the physical system whose state defines and maintains the measurement basis (e.g. an interferometer phase-locking loop, a qubit readout chain, the active feedback in a precision interferometer). '''Held constant''': the environmental temperature ''T'' at which the controller operates, by independent active thermal feedback. Holding ''T'' constant while varying ''P'' is what distinguishes the framework's prediction from standard thermal decoherence (which depends on ''T'' and ignores ''P''). '''Dependent variable''': the visibility-decay breakdown time ''t''<sub>break</sub>, fitted to interference data at a chosen visibility threshold (e.g. ''V''* = 0.5). '''Prediction''': ∂''t''<sub>break</sub>/∂''P'' > 0 at clamped ''T'', with the visibility curve ''V''(''t'') fitting the double-exponential form exp(−½ σ<sub>0</sub><sup>2</sup> e<sup>2κ''t''</sup>) better than a standard exponential ''e''<sup>−Γ''t''</sup> or Gaussian ''e''<sup>−γ''t''²</sup>. '''What would count as falsification'''. Any of the following null findings counts against the framework: * ∂''t''<sub>break</sub>/∂''P'' ≤ 0 at clamped ''T'' (i.e. increasing controller power does not extend, or shortens, coherence time); * ''V''(''t'') fits a single-exponential or Gaussian dephasing law significantly better than the double-exponential form, in the regime where the framework predicts the double-exponential should dominate; * ''t''<sub>break</sub> scales with the gravitational self-energy timescale ''t''<sub>OR</sub> ∝ ''s'' / ''m''<sup>2</sup> (the [[Penrose interpretation of quantum mechanics|Penrose Objective Reduction]] prediction) rather than with ''C''<sub>eff</sub>; * ''C''<sub>eff</sub> cannot be calibrated independently of ''t''<sub>break</sub> (in which case the prediction would be unfalsifiable, which would itself count against the framework's experimental status). The [https://www.qgemproject.com/ QGEM] pathfinder is cited in the BLQC manuscript as one candidate testbed; superconducting-qubit readout chains and precision interferometer phase-locking loops are others. == Relation to quantum foundations == The framework is connected to, and partly draws from, several existing positions in the foundations of quantum mechanics. * '''Brukner's information-theoretic reconstructions''' provide a precedent for treating information limits as structural constraints in quantum theory. * '''Relational Quantum Mechanics''' (Rovelli) takes measurement outcomes to be relative to an observer-system; the framework provides one possible mechanism (finite ''C''<sub>eff</sub>) for what makes one observer's frame physically inequivalent to another's. * '''Decoherence theory''' is not opposed by the framework. The framework's prediction sits beside ordinary environmental decoherence and is intended to be ''distinguishable'' from it by the sign-reversal under power variation; in the capacity-wins regime (κ < 0) standard decoherence theory is recovered. * '''Measurement-independence'''. Because the framework treats the measurement basis as a dynamical variable with its own causal history, if extended to Bell-type set-ups it appears to imply a structural violation of statistical measurement-independence. The framework's response to the conventional "conspiracy" objection against superdeterminism is to attribute the correlation to common causal past plus a global consistency constraint rather than to fine-tuned initial conditions. This response is philosophical rather than mathematical and the formal extension (including a no-signalling treatment) is itself an open question (see [[#Open objections|Open objections]]). * '''Penrose Objective Reduction''' is treated as an ''orthogonal'' competing mechanism whose predicted ''t''<sub>OR</sub> ∝ ''s'' / ''m''<sup>2</sup> scaling can be experimentally distinguished from the framework's ''C''<sub>eff</sub>-driven ''t''<sub>break</sub>. The numerical proximity of the two timescales in the mesoscopic regime motivates the protocol described in the next section but is treated as a coincidence pending experimental evidence. == Philosophical interpretation == ''This section describes interpretive extensions of the framework that go beyond the empirical core. Nothing in this section is a load-bearing element of the experimental claim. If the experimental discriminator returns a null result, the claimed physical realization of these interpretive readings within the framework would fall. The interpretive positions themselves — Advaita Vedānta, relational quantum mechanics — do not stand or fall on an interferometry experiment; what stands or falls is the framework's specific physical mapping into them.'' A direct statement of the framework's interpretive position appears in ''[https://ignorantobserver.xyz/documents/Hard_Problem_After_Deflation.pdf The Hard Problem Dissolved — But Into What? A Critical Response to Carlo Rovelli's "There Is No 'Hard Problem of Consciousness'"]'' (Dekker, May 2026). The response engages Rovelli's recent Noema essay, marks the substantial ground it shares with the framework, and identifies where the framework presses beyond Rovelli's deflationary physicalism toward a non-dual reading. Readers approaching the framework from philosophy of mind may find that essay the most accessible entry point. The framework's interpretive layer is developed in dialogue with two existing positions. The first is Carlo Rovelli's relational quantum mechanics. The framework can be read as supplying a candidate physical mechanism — the ''C''<sub>eff</sub> versus ''h''<sub>KS</sub> inequality — for what makes a measurement outcome relative to an observer rather than absolute. On this reading, the framework is a mechanistic specification of an idea that RQM leaves at the level of principle. The second is the Advaita Vedānta tradition (Śaṅkara, Ramaṇa Mahaṛṣi), in which the apparent independence of the experiencing subject from the perceived world is treated as a structural feature of ignorance (''avidyā'') rather than a metaphysical fact. The framework's σ<sub>θ</sub><sup>2</sup>(''t'') — the growing basis-tracking error of an observer whose capacity is insufficient to track its own apparatus — admits a structural analogy with avidyā as the phenomenological self-opacity of an embodied subject. The framework neither asserts that this analogy is more than structural nor that any experimental result could confirm or refute Advaita as a philosophical position; it offers the analogy as a way of locating the framework within a non-dual reading of the measurement problem for readers who find that reading useful. Readers who prefer to ignore both interpretive readings should be able to evaluate the framework's empirical content from the [[#Technical proposal|Technical proposal]] and [[#Experimental discriminator|Experimental discriminator]] sections alone. A further speculative extension, ''[https://ignorantobserver.xyz/documents/Creation_of_Duality.pdf The Creation of Duality]'', asks whether space, time, objecthood, and gravity-like structure can themselves be read as features of a consistent finite-observer world-model, with a Bridge Ansatz ''E''<sub>G</sub> = (π/2)ℏκ linking the deficit rate κ to a gravitational energy scale via Margolus–Levitin saturation. Its scientific status is contingent on the BLQC experimental discriminator; until then it is offered explicitly as speculation. == Documents == The framework's documents are published at [https://ignorantobserver.xyz ignorantobserver.xyz].

A full archival deposit of the framework's documents is also available on the Open Science Framework at [https://doi.org/10.17605/OSF.IO/FCDSN doi.org/10.17605/OSF.IO/FCDSN]. == Open objections == The following objections to the framework are listed openly so that reviewers can engage with them directly. Several are diagnosed in the framework's own manuscripts; others reflect critiques the author has received in correspondence or anticipates from sophisticated readers. They are deliberately phrased from outside the framework's assumptions, not from within them. # '''Useful capacity versus thermodynamic bound'''. The framework uses the Landauer expression ''C'' ≤ ''P'' / (''k''<sub>B</sub> ''T'' ln 2) to relate controller input power ''P'' to channel capacity. Landauer is an ideal upper bound on bit-erasure cost; it does not guarantee that increased ''P'' actually translates to increased ''useful'' basis-tracking capacity. Additional power can equally well couple to actuator noise, electromagnetic leakage, vibration, or backaction channels that do not constrain the basis variable θ. Establishing that Δ''P'' → Δ''C''<sub>eff</sub> in the predicted direction — with realistic loss budgets for the candidate apparatus — is a substantive engineering claim that the framework does not by itself establish. # '''Existence of positive ''h''<sub>KS</sub> in engineered apparatus'''. Many precision controllers (phase-locked loops, qubit readout chains, interferometer servo systems) are explicitly engineered to suppress chaotic dynamics. The basis-defining degrees of freedom may exhibit colored noise, slow drift, or stochastic control error rather than positive-''h''<sub>KS</sub> chaos in the Pesin sense. If the relevant dynamics are not chaotic in this sense, the ''h''<sub>KS</sub> framing may not apply at all, and a different rate-distortion accounting (or none) would be needed. Even where positive ''h''<sub>KS</sub> can be identified, the operationally relevant rate may differ substantially from textbook surrogate estimates (kicked rotor, logistic map) used illustratively in the manuscripts. # '''Rate-distortion extension to nonlinear / chaotic systems'''. The mapping from channel capacity ''C'' to angular tracking variance σ<sub>θ</sub><sup>2</sup> ≥ ''D''/(''C'' ln 2) assumes a high-rate coder model and the framework extends the Data-Rate Theorem from linear plants to nonlinear chaotic systems by substituting ''h''<sub>KS</sub>. This extension is an explicit assumption, not a proven theorem. If the extension fails, the closed-form visibility law and the κ-regime structure both lose their derivation. # '''Gaussian small-angle assumption'''. The visibility expression ''V''(''t'') = exp(−½ σ<sub>θ</sub><sup>2</sup>) requires σ<sub>θ</sub> ≲ 1 rad and a Gaussian basis-tracking error distribution. Non-Gaussian, heavy-tailed, or state-dependent δθ would break the closed-form double-exponential law. # '''Decoherence and control-noise confound'''. Distinguishing the predicted visibility loss from ordinary environmental dephasing, alignment drift, and detector systematics is the central experimental challenge. The framework's answer is the sign-reversal under power variation at clamped ''T'' — a conceptually clean discriminator that is engineering-hard to realise. Independent calibration of ''C''<sub>eff</sub> may be the single largest practical hurdle. # '''Prior-art and reparameterization risk'''. The proposed double-exponential visibility signature may already be expressible within existing frameworks: compound dephasing channels with two or more contributing rates, classical feedback-loop instability, or hidden-variable control-noise models with appropriate parameter choices. The framework should be able to show that its prediction is genuinely new rather than a reparameterization of one of these known phenomena. The author's adversarial-mimic analysis is in progress, and a positive result on that front would substantially strengthen the framework's empirical claim. # '''Bell / locality consistency'''. The framework implies a structural violation of statistical measurement-independence. The author's response (common causal past plus global consistency, in place of fine-tuned initial conditions) is a philosophical reframing rather than a no-signalling lemma. A proper consistency proof has not been published. # '''Forensic-signature interpretation'''. The Forensic Signatures preprint applies a screening protocol to existing data from Chinese 63-qubit processors, Google Sycamore, and LIGO glitch records. The paper's own domain-of-validity statement is that BLQC applies in observer-limited rather than plant-limited regimes, and the protocol finds power-law dominance on the qubit datasets (consistent with that statement) and 43% Gompertz-consistent events on LIGO (consistent with BLQC). The paper flags a controller-regime confound for the LIGO result and is explicit that retrospective findings do not establish causal attribution to BLQC; the case rests on the prospective controlled-capacity experiment. The objection here is the standard one for retrospective signal analyses: even where the predicted geometry is present, it remains compatible with alternative explanations until the controlled experiment runs. # '''Observer language'''. The framework's "observer" plays two distinct roles: the physical apparatus / controller whose finite ''C''<sub>eff</sub> and ''h''<sub>KS</sub> appear in the equations, and the epistemic subject for whom measurement outcomes are or are not determinate. The framework treats these as connected but not identified, and the distinction is load-bearing. Critics will reasonably worry — especially given the framework's interpretive engagement with non-dual philosophy and the philosophy of mind — that consciousness is being smuggled into the foundations of measurement under physical vocabulary. The framework's defence is that the BLQC experimental claim is stated entirely in apparatus-level terms; whether that defence holds depends on the framework keeping the two senses of "observer" rigorously separate. # '''Interpretive vocabulary'''. Some of the framework's documents draw on vocabulary from philosophy of mind and non-dual philosophy (notably Advaita Vedānta) alongside the physical derivations. Readers who find this vocabulary off-putting are invited to evaluate the empirical content from the BLQC manuscript, which uses only standard physics and control-theory language. # '''Peer-review status and independent replication'''. The framework has not yet undergone peer review, and the experimental discriminator has not been independently replicated. This is the actual current epistemic status of the work. The framework's case must be evaluated on its merits in the documents linked above and on the conduct of the prospective experiment, not on any external imprimatur. == Invitation for review == This page is offered as a venue for substantive critique. The author is particularly interested in engagement on the following: * '''From physicists working on quantum control or precision interferometry''': is the proposed sign-reversal under controller-power variation at clamped temperature genuinely distinguishable from known instrumental artefacts (closed-loop resonances, thermal-noise mismodelling, photon-shot-noise rebalancing at higher gain), and what existing apparatus would be best positioned to perform the test? * '''From decoherence theorists''': under what conditions does the proposed double-exponential visibility law overlap with compound-channel decoherence models in ways that would make the two empirically indistinguishable? Is there a parameter regime where the framework's prediction is genuinely new rather than a reparameterisation of existing models? * '''From researchers in the foundations of quantum mechanics''': how should the framework's structural violation of measurement-independence be evaluated against the alternatives in the superdeterminism / retrocausality / many-worlds landscape, and what would constitute a satisfactory consistency proof? * '''From philosophers of mind''': the Advaita / RQM interpretive layer is offered conditionally on the empirical core. Is the conditional structure ("these readings are available ''if'' the empirical claim survives") presented clearly enough, or does it still amount to overreach? Comments, references to prior or parallel work the author may not be aware of, and pointers to potential confounds or alternative explanations are all welcome.
