I am proposing that we remove this qualification and allow for indefinite interface admin status. I think this is useful because there are reasons for tweaking the site CSS or JavaScript (e.g. to comply with dark mode), add gadgets (e.g. importing Cat-a-Lot, which I would like to do), or otherwise modifying the site that could plausibly come up on an irregular basis and requiring the overhead of a bureaucrat to add the user rights is inefficient. In particular, I am also going to request this right if the community accepts indefinite interface admins.

I do not believe including a small note/reference that a page is AI-generated is sufficient, and I take my thinking from [[WV:Original research|Wikiversity's OR policy]] for OR work: ''Within Wikiversity, all original research should be clearly identified as such''. I believe resources created from AI should also be clearly indicated as such, especially since we are working on whether or not AI-generated resources should be allowed on the website (discussion is [[Wikiversity talk:Artificial intelligence|here]], for reference). This makes it easier for organizational purposes, and in the event ''if'' we ban AI-generated work.

This is useful, especially considering the notable issues with AI (including hallucinations and fabrication of details), so viewers and support staff are aware.

The new banner is unduly large and alarming. There is no need for alarm here. The use of AI is not harmful per se. Like any technology, it can be used to help or to harm. I take care to craft prompts carefully, point the LMM to reliable source materials, and to carefully read and verify the generated text before I publish it. This is all in keeping with long-established Wikiversity policy. We don't want to use a  [[w:One-drop_rule|one-drop rule]] here or cause a [[w:Satanic_panic|satanic panic]]. We can learn our lessons from history here. I don't see any pedagogical reason for establishing a classification of "AI generated", but if there is a consensus that it is needed, perhaps it can be handled as just another category that learning resources can be assigned to.

[[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.

'''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.

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.

I do not believe including a small note/reference that a page is AI-generated is sufficient, and I take my thinking from [[WV:Original research|Wikiversity's OR policy]] for OR work: ''Within Wikiversity, all original research should be clearly identified as such''. I believe resources created from AI should also be clearly indicated as such, especially since we are working on whether or not AI-generated resources should be allowed on the website (discussion is [[Wikiversity talk:Artificial intelligence|here]], for reference). This makes it easier for organizational purposes, and in the event ''if'' we ban AI-generated work.

[[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]]. We are migrating this data (across roughly 4,000 items) to a newly created, dedicated property: '''[[:d:Property:P14226|P14226]]'''. '''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.

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.

[[User:Codename Noreste|Codename Noreste]] ([[User talk:Codename Noreste|discuss]] • [[Special:Contributions/Codename Noreste|contribs]]) 00:28, 25 April 2026 (UTC) == Is anyone interested in Neurodiversity? == Is anyone interested in Neurodiversity? 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.

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 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. I don't want to raise attention that I'm unsure whether I'll actually be capable of developing a methodology for but project notes is my best bet so far in tracking my progress.

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.

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.

In many ways, this is exactly what an open collaborative learning community should be doing.

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. I don't want to raise attention that I'm unsure whether I'll actually be capable of developing a methodology for but project notes is my best bet so far in tracking my progress.

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.

I am requesting interface administrator access on this wiki. The main reasoning is that I would benefit from having the user right <code>editinterface</code>, which would allow me to make dark mode changes to pages in the MediaWiki namespace, add <code><nowiki><div class="mw-parser-output"></nowiki></code> to some interface pages using templates, handle interface-protected edit requests, and similar stuff. Additionally, I have some knowledge of CSS, and I would like to assist with modifying CSS pages whenever necessary, such as moving MediaWiki common.css code to TemplateStyles CSS pages. I am requesting the maximum time that is allowed per the [[Wikiversity:Interface administrators|policy]], and I have 2FA enabled on my account. Thank you.

I think this is useful because there are reasons for tweaking the site CSS or JavaScript (e.g. to comply with dark mode), add gadgets (e.g. importing Cat-a-Lot, which I would like to do), or otherwise modifying the site that could plausibly come up on an irregular basis and requiring the overhead of a bureaucrat to add the user rights is inefficient.

I believe resources created from AI should also be clearly indicated as such, especially since we are working on whether or not AI-generated resources should be allowed on the website (discussion is [[Wikiversity talk:Artificial intelligence|here]], for reference).

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!).

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.

Google output read that no such thing exists so I wanted it mainly to be unique. I don't want to raise attention that I'm unsure whether I'll actually be capable of developing a methodology for but project notes is my best bet so far in tracking my progress.

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.

I do not believe including a small note/reference that a page is AI-generated is sufficient, and I take my thinking from [[WV:Original research|Wikiversity's OR policy]] for OR work: ''Within Wikiversity, all original research should be clearly identified as such''. I believe resources created from AI should also be clearly indicated as such, especially since we are working on whether or not AI-generated resources should be allowed on the website (discussion is [[Wikiversity talk:Artificial intelligence|here]], for reference).

[[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.

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 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.

I do not believe including a small note/reference that a page is AI-generated is sufficient, and I take my thinking from [[WV:Original research|Wikiversity's OR policy]] for OR work: ''Within Wikiversity, all original research should be clearly identified as such''. I believe resources created from AI should also be clearly indicated as such, especially since we are working on whether or not AI-generated resources should be allowed on the website (discussion is [[Wikiversity talk:Artificial intelligence|here]], for reference). This makes it easier for organizational purposes, and in the event ''if'' we ban AI-generated work.

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]]. We are migrating this data (across roughly 4,000 items) to a newly created, dedicated property: '''[[:d:Property:P14226|P14226]]'''. '''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.

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 was brainstorming yesterday about it. 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. I don't want to raise attention that I'm unsure whether I'll actually be capable of developing a methodology for but project notes is my best bet so far in tracking my progress.

[[User:Codename Noreste|Codename Noreste]] ([[User talk:Codename Noreste|discuss]] • [[Special:Contributions/Codename Noreste|contribs]]) 00:28, 25 April 2026 (UTC) == Is anyone interested in Neurodiversity? == Is anyone interested in Neurodiversity? 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.

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 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 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.

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. I don't want to raise attention that I'm unsure whether I'll actually be capable of developing a methodology for but project notes is my best bet so far in tracking my progress.

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.

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. I don't want to raise attention that I'm unsure whether I'll actually be capable of developing a methodology for but project notes is my best bet so far in tracking my progress.

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.

I am requesting interface administrator access on this wiki. The main reasoning is that I would benefit from having the user right <code>editinterface</code>, which would allow me to make dark mode changes to pages in the MediaWiki namespace, add <code><nowiki><div class="mw-parser-output"></nowiki></code> to some interface pages using templates, handle interface-protected edit requests, and similar stuff. Additionally, I have some knowledge of CSS, and I would like to assist with modifying CSS pages whenever necessary, such as moving MediaWiki common.css code to TemplateStyles CSS pages. I am requesting the maximum time that is allowed per the [[Wikiversity:Interface administrators|policy]], and I have 2FA enabled on my account. Thank you.

I believe resources created from AI should also be clearly indicated as such, especially since we are working on whether or not AI-generated resources should be allowed on the website (discussion is [[Wikiversity talk:Artificial intelligence|here]], for reference).

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!).

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.

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.

I do not believe including a small note/reference that a page is AI-generated is sufficient, and I take my thinking from [[WV:Original research|Wikiversity's OR policy]] for OR work: ''Within Wikiversity, all original research should be clearly identified as such''. I believe resources created from AI should also be clearly indicated as such, especially since we are working on whether or not AI-generated resources should be allowed on the website (discussion is [[Wikiversity talk:Artificial intelligence|here]], for reference). This makes it easier for organizational purposes, and in the event ''if'' we ban AI-generated work.

Not to even mention this user's contributions to the English Wikipedia have been [https://en.wikipedia.org/wiki/Wikipedia:Articles_for_deletion/Inner_Development_Goals contested] and [https://en.wikipedia.org/wiki/Wikipedia:Articles_for_deletion/Multipolar_trap removed] a couple of times (for being low-quality and clearly LLM-generated), highlighting the need for an actual policy to be implemented here on Wikiversity. I would like to ping {{ping|Juandev}} and {{ping|Jtneill}} for their thoughts as well, since I'd like this to be implemented as soon as possible. Wikiversity has a significant issue with implementing anti-disruptive measures, hence why we have received numerous complaints as a community about our quality. I originally was reverting the removal of the templates, but realized that this is still a proposed policy, which it shouldn't be anymore. It should be a recognized Wikiversity policy. 14:54, 10 March 2026 (UTC) —[[User:Atcovi|Atcovi]] [[User talk:Atcovi|(Talk]] - [[Special:Contributions/Atcovi|Contribs)]] 14:54, 10 March 2026 (UTC) :@[[User:Atcovi|Atcovi]] '''I agree''' that the draft, should become official policy.

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.

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.

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.

I think this is useful because there are reasons for tweaking the site CSS or JavaScript (e.g. to comply with dark mode), add gadgets (e.g. importing Cat-a-Lot, which I would like to do), or otherwise modifying the site that could plausibly come up on an irregular basis and requiring the overhead of a bureaucrat to add the user rights is inefficient.

I do not believe including a small note/reference that a page is AI-generated is sufficient, and I take my thinking from [[WV:Original research|Wikiversity's OR policy]] for OR work: ''Within Wikiversity, all original research should be clearly identified as such''. I believe resources created from AI should also be clearly indicated as such, especially since we are working on whether or not AI-generated resources should be allowed on the website (discussion is [[Wikiversity talk:Artificial intelligence|here]], for reference). This makes it easier for organizational purposes, and in the event ''if'' we ban AI-generated work.

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>).

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.

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.

I am proposing that we remove this qualification and allow for indefinite interface admin status. I think this is useful because there are reasons for tweaking the site CSS or JavaScript (e.g. to comply with dark mode), add gadgets (e.g. importing Cat-a-Lot, which I would like to do), or otherwise modifying the site that could plausibly come up on an irregular basis and requiring the overhead of a bureaucrat to add the user rights is inefficient.

I do not believe including a small note/reference that a page is AI-generated is sufficient, and I take my thinking from [[WV:Original research|Wikiversity's OR policy]] for OR work: ''Within Wikiversity, all original research should be clearly identified as such''. I believe resources created from AI should also be clearly indicated as such, especially since we are working on whether or not AI-generated resources should be allowed on the website (discussion is [[Wikiversity talk:Artificial intelligence|here]], for reference).

[[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>).

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.

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.

I believe resources created from AI should also be clearly indicated as such, especially since we are working on whether or not AI-generated resources should be allowed on the website (discussion is [[Wikiversity talk:Artificial intelligence|here]], for reference).

[[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!).

'''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 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.

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.

Athena problem is: Give a [[:w:radix|base]] ''b'', write all [[:w:prime number|prime number]]s > ''b'' in the [[:w:positional notation|positional notation]] with base ''b'', and regard them as [[:w:string (computer science)|string]]s, and find the [[:w:set (mathematics)|set]] of the [[:w:minimal element|minimal element]]s of the set of these strings under the [[:w:subsequence|subsequence]] [[:w:partially ordered set|ordering]]. By [[:w:Higman's lemma|Higman's lemma]], there are no [[:w:infinite set|infinite]] [[:w:antichain|antichain]]s for the subsequence ordering, thus there must be only finitely many such minimal elements, in other words, the set of such minimal elements must be a finite set. == Results == These are the results of the Athena problem in bases 2 <= ''b'' <= 28: All numbers are written in ''b'', using A to Z to represent digit values 10 to 35, "{}" means repeating, for example, 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).

[[:w:List of unsolved problems in mathematics|unsolved problem]] in [[:w:number theory|number theory]] and [[:w:formal language theory|formal language theory]] and [[:w:order theory|order theory]], this problem is named after the ancient Greek goddess [[:w:Athena|Athena]]. Athena problem is: Give a [[:w:radix|base]] ''b'', write all [[:w:prime number|prime number]]s > ''b'' in the [[:w:positional notation|positional notation]] with base ''b'', and regard them as [[:w:string (computer science)|string]]s, and find the [[:w:set (mathematics)|set]] of the [[:w:minimal element|minimal element]]s of the set of these strings under the [[:w:subsequence|subsequence]] [[:w:partially ordered set|ordering]]. By [[:w:Higman's lemma|Higman's lemma]], there are no [[:w:infinite set|infinite]] [[:w:antichain|antichain]]s for the subsequence ordering, thus there must be only finitely many such minimal elements, in other words, the set of such minimal elements must be a finite set. == Results == These are the results of the Athena problem in bases 2 <= ''b'' <= 28: All numbers are written in ''b'', using A to Z to represent digit values 10 to 35, "{}" means repeating, for example, 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).

"authority hack" user page deletion */ Not undeleted per requester request drop, archived 2808152 wikitext text/x-wiki {{/header}} [[Category:Wikiversity deletion]] __TOC__ == [[Korean/Words]] == (I go to RfD instead of ''proposed deletion'' since many pages are affected.) 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?

[[User:Juandev|Juandev]] ([[User talk:Juandev|discuss]] • [[Special:Contributions/Juandev|contribs]]) 08:38, 11 March 2026 (UTC) == [[Enhancing Web Browser Security through Cookie Encryption]] == To avoid further conflict with the user who entered this text into Wikiversity, I am opening a RFD request. 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.

I cannot imagine this is a recommended practice in academic publishing. At a minimum, somewhere near the top, the page should say something like the following: "This text is based on article ___ published at ___ but is not identical. The author of the differences/changes is ___." Everything else leads to an undesirable confusion.

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.

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!".

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.

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!".

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 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.

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.

And it's not a strange or unreasonable argument to make that since Earth has existed for long, it's more likely that aliens have come here in the past than in recent times or the near future. Instead of insulting others' intelligence, maybe engage with the actual reasoning rather than censoring it away.

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.

Custodians are the Wikiversity equivalent of administrators, also known as sysops, bibliotecarios&nbsp;(librarians), and moderators. The English Wikiversity currently has {{NUMBEROFADMINS}} custodian{{PLURAL:{{NUMBEROFADMINS}}||s}} ([[Special:ListUsers/sysop|full list]]), including human and bot users. {{center top}}'''[[Wikiversity:Request custodian action|Request assistance]]''' - '''[[Wikiversity:Support staff#Support staff directory|List of custodians]]''' - '''[[Wikiversity:Candidates for Custodianship|Requests for custodianship]]'''{{center bottom}} == How does one become a custodian? == {{shortcut|WV:CUST/HOW}} Any [[Wikiversity:Who are Wikiversity participants?|Wikiversity participant]] willing to do a lot of [[#What can custodians do?|dull and boring work]] for the community can become a custodian. If you have a good editing record then you are likely to be trusted and granted the privileges and responsibilities of custodianship. If you are still interested in custodianship, here is the process it takes: {| 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 custodianship at [[Wikiversity:Candidates for Custodianship|Candidates for Custodianship]]. 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 custodian privileges in accordance with established policy and community consensus. If any experienced custodians agree to mentor you and you agree to their mentorship, then you will be approved as a [[w:Probation (workplace)|probationary]] custodian for a period of at least '''four weeks'''. You will have all the privileges described below. 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 before the probationary period is complete, you will have 48 hours to find a new mentor. Otherwise your mentor may [[Meta:SRP|request removal of custodian privileges]] after 48 hours, without any further notice or community discussion. |- | style="padding: 10px; text-align: center" | III | <div id="Evaluation"> ;Evaluation </div> Your mentor will submit a request for comments at [[Wikiversity:Candidates for Custodianship|Candidates for Custodianship]] for a period of at least seven days when you are ready. During that period Wikiversity participants can evaluate how well the custodian privileges are used and how you conducted yourself at Wikiversity. |- | style="padding: 10px; text-align: center" | IV | <div id="Custodianship"> ;Custodianship </div> After one week of evaluation, a bureaucrat will make the final decision based on the arguments provided in the discussion. If you are approved, you will be a [[#Notes|permanent custodian]]. If you are not approved, your probationary period may either be extended or you may request another mentorship later. |} == What can custodians do? == {{shortcut|WV:CUST/WHAT}} === Deletion and undeletion of pages === {{shortcut|WV:CUST/D}} [[File:Delete and Protect buttons.png|200px|right]] Custodians can delete pages including images, categories, templates, etc. 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 is merely invisible to non-custodians and can be restored at request, which may be submitted at [[Wikiversity:Requests for Deletion]]. Page deletions and undeletions can be monitored by viewing the [[Special:Log/delete|deletion log]]. Custodians can also delete individual versions with the [[Wikiversity:Revision deletion|RevisionDelete]] feature. This is particularly useful to remove materials that violate [[Wikiversity:Copyrights|copyrights]] or other applicable law. Before you delete a page, read: [[Wikiversity:Welcome templates]]. See also: [[Wikiversity:Deletion policy]]. === Edit and move protection of pages === Custodians 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 from editing. A page can also be protected to prevent moving. Page protection can be lifted by any custodian upon request, which may be submitted at [[Wikiversity:Request custodian action]]. Page protections and unprotections can be monitored by viewing the [[Special:Log/protect|protection log]]. === Rollback === [[Image:Rollback button.png|thumb|300px|Rollback button]] Custodians 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 "Reverted edits by [[Special:Contributions/$2|$2]] ([[User_talk:$2|talk]]) to last version by [[User:$1|$1]] using [[Wikiversity:Rollback|rollback]]" 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. === User blocks === {{shortcut|WV:CUST/B}} Custodians can block users from editing by specifying a username, an IP address or range of addresses. Blocks can be temporary or permanent. Most frequently, blocking occurs in response to obvious and repeated vandalism. When blocking a user, a reason for blocking must be provided which is displayed in the [[Special:Log/block|block log]]. It is also possible to block IP addresses from creating new user accounts. See [[Wikiversity:Blocking policy]]. === Editing MediaWiki [[Wikiversity:Namespaces|namespace]] === {{shortcut|WV:CUST/MW}} Custodians are able to edit system messages (the standard texts that are used by the MediaWiki software). === Import === Custodians have access to the [[Special:Import|Import tool]], to bring materials from Wikipedia, Wikibooks, Beta.Wikiversity, Wikiquote, and Wikisource. == How are custodians expected to act? == {{shortcut|WV:CUST/E}} Custodians 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]]. For a discussion of possible failure to act professionally, see a proposed recusal policy at [[Wikiversity:Recusal]]. ==Problems with custodians== {{shortcut|WV:CUST/P}} If you have a question about an action (page deletion, page protection, user block, editing MediaWiki namespace pages, violation of Wikiversity policy or some other action that does serious damage to the project) by a Wikiversity custodian, the first thing to do is leave a message on that custodian's user discussion page. Custodians should always be able to explain how their actions support Wikiversity. If you cannot get satisfaction from discussion with the custodian, you can place comments, suggestions, complaints or questions at [[Wikiversity:Custodian feedback|Custodian feedback]]. Try to resolve all custodian problems by discussion. Custodians can lose their status for [[wikt:egregious|egregious]] violations of policies. Loss of custodianship involves a process that establishes community consensus. If a specific complaint is not resolved at [[Wikiversity:Custodian feedback|Custodian feedback]] then a [[Wikiversity:Community Review|Community Review]] can be initiated to establish if there is community consensus in support for the custodianship of the custodian who is the subject of the unresolved complaint. At the end of the review, Wikiversity bureaucrats will review the discussion. If a bureaucrat decides that there is good reason for removal of a custodianship, that bureaucrat will go to the meta-wiki and [[m:Requests for permissions|request]] that stewards review the community discussion. If a steward agrees that the Wikiversity community has reached consensus about a problem custodian, then that steward can terminate the custodianship of the custodian. If you have a question about an action of a probationary custodian, you should consult their mentor(s). Actions of a probationary custodian are the responsibility of their mentor(s) during their probationary period. Partially depending on agreements made in the probationary candidacy, and with respect for the 48 hour period to find a new mentor, a request to remove custodianship for a probationary custodian may often be made at Meta by any mentor or bureaucrat without need for community consensus. The local process to remove custodianship should only need to be used as a last resort, because of this alternative option. == Notes == {{shortcut|WV:CUST/N}} * Custodianship is a responsibility, not a right. While everyone is encouraged to apply for custodianship, the position is not suited for everyone. Please also note that in all instances not listed above, custodians have no more power or weight than other users. * Custodians 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]]. * The maximum time period of inactivity <u>without community review</u> for holders of advanced administrative rights is two years per the [[:meta:Category:Global policies|global policy]] described at [[meta:Admin activity review|Admin activity review]]. After that time, a [[meta:Stewards|steward]] will remove the rights.<ref>See also a decision apparently made in [[Wikiversity:Request custodian action/Archive/24#Reviews for Inactivity]].</ref> == Useful reads for custodians == {{Wikiversity organization}} ===Wikiversity=== * [[Wikiversity:Blocking policy]] * [[Wikiversity:No shrines for vandals]] * [[Wikiversity:Policies]] * [[Wikiversity:Revision deletion]] * [[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/sysop|List of current Wikiversity custodians and bureaucrats]] *[[Wikiversity:Bureaucratship]] *[[Wikiversity:Candidates for Custodianship]] *[[Wikiversity:CheckUser policy]] *[[Wikiversity:Curators]] *[[Wikiversity:History of Wikiversity/Custodianship]] *[[Wikiversity:Support staff|Wikiversity:Staff]] *[[Special:ListGroupRights]] *[[Wikiversity:Request_custodian_action/Archive/24#Reviews_for_Inactivity]] (Inactivity policy for Wikiversity Custodians) {{Official policies}} [[Category:Wikiversity custodianship| ]] 1ipkqtvqjxhz5nl9bzys7pwxpn7419m User talk:Koavf 3 4866 2808150 2806794 2026-05-10T08:12:38Z Juandev 2651 /* Need of IAs */ new section 2808150 wikitext text/x-wiki {| style="border-spacing:8px;margin:0px -8px" width="100%" |class="MainPageBG" style="width: 55%; border:1px solid #084080; background-color:#F5FFFA; vertical-align:top;color:#000000;font-size: 85%"| {| width="100%" cellpadding="2" cellspacing="5" style="vertical-align:top; background-color:#F5FFFA" ! <div style="margin: 0; background-color:#CEF2E0; font-family: sans-serif; font-size:120%; font-weight:bold; border:1px solid #084080; text-align:left; color:#082840; padding-left:0.4em; padding-top: 0.2em; padding-bottom: 0.2em;"> '''Hello Koavf!

Wikiversity is disconcerting to those familiar with the encyclopedia projects, and the other content-oriented projects. While we do have a content mission, we ''also'' have a "learning by doing" mission, which is about ''people.'' Our product is not just content, it is education, and there is no education without users who are educated, and sophisticated education is always about process and people skills and the rest. I would argue that the encyclopedia projects also need to be welcoming, if the full mission is to be fulfilled, but ... they developed with a very narrow focus and absent the realization that an environment that was easily seen as hostile would damage the mission. The 20th century saw the development of systems and skills and process for maximizing consensus, and the only reliable measure of neutrality is level of consensus. (I.e., if everyone involved agrees, 100% consensus, while what they agree upon only might possibly turn out, in the end, to be defective or invalid, there is no better measure!). So to the extent that there is exclusion, to that extent, the assessment of neutrality can be warped. Obviously, compromises are necessary, but "compromise" requires tolerating a level of damage, and that is easily forgotten. When the importance of consensus being as broad as possible is realized, a community will find ways to keep conversation open, on some level, in some place, otherwise the community becomes locked into what I call the "tyranny of the past." There is a children's song that was part of a therapeutic response to Reactive Attachment Disorder: :'''There is always something you can do, do, do''' :'''When you're getting in a stew, stew, stew.''' Mostly, it involves simmering down, dropping upset and reactive response, and, when calm, communicating. While this kind of work has been done on Wikipedia, often in user space -- it's what I did, successfully mediating disputes, such that users at each other's throats became cooperative ''with each other'' -- this was mumbo-jumbo nonsense to too many on Wikipedia. For example, see [https://en.wikipedia.org/wiki/Wikipedia:Miscellany_for_deletion/Abd_user_pages], which included many pages of historical function, including evidence presented to ArbCom. I found it very strange that ArbCom did not care that evidence used in a case was being deleted, but ArbCom consists of too many elevated beyond their competence by popularity (as well as many other highly-experienced and thoughtful user; but the system tends to burn them out and they become less attentive.) [[w:User:Abd/Dispute over thermoeconomics]] was particularly educational. In that mediation, a professor was revert warring with Randy from Boise, so to speak, and one or both were about to be blocked. It took very little to develop cooperation, mostly just sitting them down together with some support. Hmmm... I'm thinking of asking that these pages be transwikied to Wikiversity, precisely for historical study. Looking for the link to that, I came across [https://en.wikipedia.org/wiki/Wikipedia:Miscellany_for_deletion/User:UBX/Esperanza_returns this]. It shows a quick and major clue to what happened on en.wiki. Two three-letter users with a conflict. One was an administrator taken to ArbCom by the other, and the administrator was trout-slapped by ArbCom and then, it is obvious, revenge was exacted, by the admin and his friends. This was long-continued and, while not unnoticed, never sanctioned. Admins can be hostile, this one was more than hostile, he was highly insulting at times, using obscene language, and using tools while involved, was reprimanded, made small adjustments to his behavior, but continued pretty much unimpeded. And, as you know, this is not uncommon. He is even a likeable Guy. I consider this all the responsibility ''of the community.'' Blaming people for what comes naturally for them is not productive. Such people generally will modify behavior in a functional community. Notice the irony. The userbox was "Esperanza returns," referring to the project designed to foster civility and welcome and cooperation. Esperanza, of course, means Hope. So the nominator was saying, "Hope will never return." Esperanza was crushed when it temporarily was inactive. Instead of improving the governance, which was easily possible, it was crushed with ''vehemence,'' see the [[w:Wikipedia:Miscellany_for_deletion/Wikipedia:Esperanza|MfD]]. Why? To any serious student of human organizational structure, it's obvious. Wikiversity is the slim thread of hope, and if it is not protected and defended, hope will break.

Thank you for deleting files once again! You made a comment about "all local uploads". Fair-use is not allowed on Commons so the 2,712 files in [[:Category:All non-free media]] can't go to Commons. But as I understand [[Wikiversity:Requests_for_Deletion#Deleting_ALL_non-free_uploads_by_User:Marshallsumter]] the files uploaded by Marshallsumter could be deleted. That would eliminate 1,126 files. Since [[Wikiversity:Uploading_files#Exemption_Doctrine_Policy]] allow fair use it would require a vote/discussion to change that. Young1lim uploads many pdf-files and as far as I know Commons generally do not like pdf-files. Except when it is scans of old books etc. So I do not think those files should go to Commons right now. There are still many files in [[Special:UnusedFiles]]. Right now 1,422 but some are uploaded by Young1lim. But the latest deletion request ended with delete so I think there is concensus to delete files. But some were also found good and moved to Commons. So the question is if we need another discussion about the files or if someone (you?) could just go through the files when you have a little time and either move to Commons or delete. If you think we could make one final discussion about all the files and ask for a go to the "any admin that want to can check the files and either move to Commons or delete". Then noone can come later and complain that you or another admin just deleted a file without warning. If there are 40k files in total. Perhaps 22k are pdf uploaded by Young1lim. 3k are non-free. 1.5k are unused. That would leave around 13.5k free files in use. That is a lot of files to check. I do not think there are many users that are willing to spend much time checking those files. But it would help if no more free files are uploaded (except pdf). There is allready a text on the top of [[Special:Upload]] suggesting commons. But it could perhaps be made more clear. And perhaps some of the options on [[MediaWiki:Licenses]] could be removed. --[[User:MGA73|MGA73]] ([[User talk:MGA73|discuss]] • [[Special:Contributions/MGA73|contribs]]) 18:01, 27 July 2024 (UTC) :Yeah, to be clear, I appreciate that sister projects like e.g. Wikibooks allow a lot of free-use files because they allow video game strategy guides and there is substantial value in screenshots or Wikipedia allows album covers and film posters as identifying media. I'm not proposing any change to policy and I accept that there are reasons for fair use, so I apologize for that sloppy wording. That said, I definitely think we should have minimal fair use if any at all. :As for PDFs, there are plenty at Commons: I have uploaded dozens and dozens of books, scientific articles, etc. It's not a problem, but it's just not optimal for many kinds of files, such as maps or something. :I'm happy to help and slog thru the uplaods if you start a conversation.

On the other hand, the template is linked from [[:Wikiversity:Copyright issues]], so while it is perhaps unused in the sense of ''not invoked'', it is ''linked to''.

This management process is intended to streamline processing of requests for user group changes, and to minimize ambiguity introduced to the process when non-bureaucrats intervene. Bureaucrats should be careful about making mistakes in adding user rights because only the ''bot'' and ''interface administrator'' groups can be removed by bureaucrats.

For example, one of the key duties of bureaucrats is to turn wiki users into sysops (called [[Wikiversity:Custodianship|custodians]] at Wikiversity). The Wikiversity community should decide if there is some set level of community support required for custodianship or if bureaucrats can exercise some discretion at the end of a community discussion about a candidate for custodianship. --[[User:JWSchmidt|JWSchmidt]] 23:39, 7 December 2006 (UTC) == Responsibilities of bureaucrats == Well, before we can really begin drafting this policy, I think we first need to take a comprehensive look at the technical rights of bureaucrats, the "non-technical" rights of bureaucrats, and the responsibilities of bureaucrats on enwikiversity. *'''Technical rigts''': To get the obvious out of the way: bureaucrats are the only local user group capable of granting a user SysOp rights--the policy of when this permission can be used is covered (to some extent) in [[Wikiversity:Custodianship]], so I'm not sure this policy will need to elaborate much upon this. Bureaucrats are also the only local group capable of granting a user Bureaucrat status--the main purpose of this policy is to decide upon when they can and cannot do this. Among their other technical rights are the ability to rename local users and the ability to grant a user bot status. I think it very important that enwikiversity draft both a user renaming policy and a thorough [[Wikiversity:Bots|bot policy]], both of which we lack at the moment. *'''Non-technical rights''': On enwiki, we regard Bureaucrats as the ultimate judges of consensus--I believe we should maintain this idea in our Bureaucratship policy. Only bureacrats should be able to close requests for adminship and bureaucratship, approve or reject requests for name changes, and I would also like to propose that they be final authority in requests for bot status. While our focus here isn't a bot approvals process, I would suggest that we use a process similar to RfA for bot status, where users are granted bot status based upon community consensus and where the bureaucrats are the judges of this consensus. *'''What crats can't do although it's logical to think that they could''': Bureaucrats do not have the technically ability nor the authority to revoke ''any'' user status--crat, bot, or sysop. Requests for desysopping and the like must go through the [[m:Stewards]]. Note that this issue is truly not one that can be debated--'twas set in stone long ago due to a crat gone mad on enwiki. *'''Expectations of bureaucrats''': First and foremost, bureacrats must be well-trusted members of the community. They must have exceptional understanding of the way things work on Wikiversity and must be ''excellent'' judges of consensus. They must demonstrate through their extensive contributions to Wikiversity that they are not rash in decision-making nor incivil nor incompetent. Also of primary importance is a bureaucrat's ability to thoroughly explain and defend the decisions or he or she makes as well the ability to admit fault. Anyway this is just some random babbling/brainstorming. Please discuss :).

What happens if bureaucrats have a disagreement? Does Wikiversity need more than two bureaucrats? --[[User:JWSchmidt|JWSchmidt]] 02:31, 9 December 2006 (UTC) ::Well, we don't want mindless drones as bureaucrats, so I think it's good to advise that (at least some) judgement should be used. But I do think that 2 thirds sounds good as a guide, (that's around 67%), which although not a strong consensus, reflects a good majority. If there is a dispute then you just cut out any sock votes, and see if it is above or below 2/3, otherwise we can just trust their judgement. [[User:MichaelBillington|Michael Billington]] ([[User talk:MichaelBillington|talk]] • [[Special:Contributions/MichaelBillington|contribs]]) 03:15, 9 December 2006 (UTC) :::You know, there might be an advantage to keep this process entirely ambiguous. Suppose we declare a threshold of 50% promotion, but in practise, essentially near unanimous support is needed. No well meaning bureaucrat candidate would aim to get 50% support, because if they did, it would signify that they are not in tune with the public consciousness that oversees this site. --[[User:HappyCamper|HappyCamper]] 03:42, 9 December 2006 (UTC) ::::2/3 makes sense only if the participants have [[meta:consensus|agreed to disagree]].

One way to do this, is to set this threshold proportional to the number of active participants, and simply have the nomination open until it is met. There will be some technicalities involved, but might be worthwhile looking into. --[[User:HappyCamper|HappyCamper]] 15:32, 10 December 2006 (UTC) (unindenting) I personally am not a fan of hardcoding rules about what percent of the populus needs to support someone for him to be made an admin. In theory, all custodianship "elections" should actually be ''discussions'' where the goal is attaining consensus, in which case the bureaucrat should then be required to not just look at numbers of supporters vs. opposers, but rather to thoroughly read through the discussion and determine what the true ''consensus'' of the community is. Nonetheless, that is often an idealist concept, and it may be a methodology that we will not be able to maintain for long. In any case, however, I belive that, though adminship is truly not a big deal, if ''one third'' or more of the community has good reason to oppose handing someone the mop, that person should not be made an admin--I would personally favor a much higher level of needed support (75-80%) before a Bureaucrat even considers making a user an admin. Codifying consensus clearly has its benefits--it spares crats a lot of work if they just have to look at numbers and it gives them an easy way to respond to disputes that arise about their actions, by simply citing numbers. But it is not the wiki way, nor should the task of bureaucrats simply be to count votes. I rather believe the most important quality of a prospective bureaucrat to be the ability to reasonably judge ''consensus'' without counting votes, the ability to make tough decisions, and the ability to adequately to defend oneself when making such decisions. That, I belive, should be our focus, rather than deciding what percentage of support constitutes consensus in all situations. Do keep in mind that [[m:Polling is evil]] and should be avoided where possible. Now to address Daanschr's concerns that "the ones who create the articles are not the ones who make the decisions"--I personally believe it best so; the major article writers tend to be the ones least concerned with administrivia such as blocking policies and deletion policies and the tedious boring tasks of clearing categories such as [[w:CAT:NSD]]. The job of an administrator is to be well-versed in policy matters, to have excellent common sense, and to serve as diplomats in disputes--while writing featured articles is an excellent way to gain knowledge in how to deal with disputes, it is by far not the only way, and I find that the major article writers tend to be the least capable of maintaining neutrality. Note as well that administrative permissions provide you, in theory at least, with no higher status in the community, no more influence in policy matters, and certainly not any extra tools to help you write better articles. Administrators are just that--administrators; they deal with administrative issues. Similarly, Bureaucrats deal with bureaucratic issues such as renaming users, flagging bots, and processing requests for adminship. Neither admins nor bureaucrats nor checkusers nor any other user group should have any greater influence over individual articles nor the policies governing all users and articles than any other user. Okay, ending babbling now. :D [[User:AmiDaniel|AmiDaniel]] ([[User talk:AmiDaniel|talk]]) 18:01, 10 December 2006 (UTC) :I don't like the idea of always trying to get consensus.

Sure, it takes longer, but I find the results tend to be much more beneficial. Note as well that by consensus I don't mean that everyone has to agree upon something for it to be done, but rather that decisions should be made by the community as a whole rather than just a handful of individuals, or even a narrow majority of the community.

We have to recognise that individuals bring particular viewpoints to the community, and that individuals have needs in terms of being heard, being valued etc. So we must place some value in individualism. But we are also here to create a collaborative project - which means we need to be able to listen to one another, discuss openly, and sometimes take criticism.

Anyone claiming to be able to accurately judge the "consensus" of a large group discussion without some kind of a straw poll .... Further, it is unlikely that a large fraction of participants at wikiversity will actually care enough about who operates the mops to participate repeatedly in "consensus" building. Sometimes, temporary closure can be a beautiful thing. I think initially most administrative functions, including bureaucrat status, should be fairly easily attained and moderately easily removed if people so trusted cannot learn to wield their priveleges/responsibilities effectively. This was the case when Wikipedia was a startup and helped grow the community and encyclopedia to critical mass. Of course, Wikipedia had a formal clearcut organizational structure that was fairly flat. There was the God King, the developers, everyone else. Adminship was essentially the result of having sufficient experience with the wiki and the community to be trusted to avoid really foolish blunders and trusted to be willing to help fix mistakes. At the moment Wikiversity is vertically taller than early Wikipedia was by approximately a Board of Directors, a committee, and possibly an informal subcommittee, stewards and bureaurcrats and custodians. Custodianship is not automatic after an initial introduction period. Anybody think this tall fuzzy infrastructure is helpful in retaining newcomers? How could we emulate the early structure of Wikipedia? Well perhaps once a year we could have a vote for an honorary "God King" who could occasionally decide tough issues for the community (those urgently requiring dramatic prompt action for the greater good or at least to avoid the greater bad ...) but usually keep quiet and let the community argue it out. Obviously our "God King" would not have the real authority that Jimbo started out with and has carefully preserved by stacking the Wikimedia Foundation board .... still I expect the Board (or a committee or a steward or a local bureaucrat or a local participant) might listen carefully when the honorary Wikiversity God King speaks regarding Wikiversity issues considering the position as a community spokesperson has been numerically substantiated by a majority of the votes cast determined legitimate and counted. Perhaps we should include term limits or restrict the candidates to former bureaucrats??? Notice that if you consider voting evil that can dramatically reduce the voting. One vote once a year and then the God King can help sort it all out by deciding the "consensus". No further straw polls required, unless of course the God King requests one.

A wiki bureaucrat should have a good understanding of the mission of the wiki and a willingness to put the success of the project ahead of consensus. Bureaucrats are in a position to do so by '''not''' acting when they are asked to act. If a bureaucrat feels that a requested action would do more harm than good, the bureaucrat can discuss the requested action before acting. "[[w:Ochlocracy|Mob rule]]" is a potential danger in any human social system that is guided by consensus. Bureaucrats can function as a check on this danger. Bureaucrats should be experienced wiki users who are always watching for situations in which the community might be rushing into a poor decision that does not really serve the long-term interests of the project. Also, too close adherence to policy can create problems. For example, if on the last scheduled day of a community discussion some new evidence is provided, it might be wise to extend the discussion rather than close it at the scheduled time. When bureaucrats are willing to do what is best for the project '''and''' explain what they are doing it can allow the community to be thoughtful and possibly avoid rushing into a regrettable course of action. Item #4 in the list (acting without consensus, above) is a bit trickier than failure to act. When bureaucrats feel forced into taking action in the absence of community consensus there should at least be consensus among bureaucrats and a clear explanation to the community of why the action is being taken. It makes sense to me that any bureaucrat action that is not supported by prior community consensus should be open to critical evaluation by the community. There was an interesting case at the English Wikipedia in which bureaucrats "broke the rules" in deciding to grant adminship to a candidate who had an unusually low level of community support. I think the Wikiversity community needs to give some thought to the best way to deal with that kind of situation. --[[User:JWSchmidt|JWSchmidt]] 19:47, 10 December 2006 (UTC) :If precedent needs to be made, the bureaucrat better be in a position to justify this rigorously.

For example, sometimes the Wikimedia Foundation central office makes a sudden decision (such as deleting a wiki page or placing an editing ban on an individual) based on the need to protect the Foundation from legal attack or threats of legal attack. Also, there are some standing Wikimedia Foundation policies that pertain to all Wikimedia Foundation projects. I do not think we can expect a bureaucrat to simply bow to community consensus if the bureaucrat knows that there is a good reason not to initiate an action called for by a community discussion. Simply put, it is possible for community consensus to fail to identify the best course of action and it is not reasonable to tell bureaucrats that they must '''always''' do what community consensus calls for. This is similar to saying that a soldier follows orders but does have to follow an order that involves doing something illegal.

Just as the rest of the community participants can bow out at will and go do something else. We probably should define what "consensus" means locally.

More often than not it ends up consisting of an evaluation of a user's entire history of contributions rather than their fitness for adminship. This is partially due to the fact that at most other projects there's usually no concrete experience with the user exercising admin features prior to the RfA. So the community is forced to use other points of reference to evaluate the candidate. At Wikiversity, we've created a process that's different from that. Candidates for custodianship are required to be mentored for four weeks, after which they are evaluated by their mentor. The point of this process is for a candidate to have the opportunity to exercise custodian tools and demonstrate the way in which they would conduct themselves as full custodians. If the mentor provides a favorable recommendation, the candidate can apply for full custodianship, subject to community discussion. The final decision in this matter lies with the bureaucrats who are expected to evaluate the mentorship period, the recommendation and community feedback. It's not so much a question of consensus but of informed decision-making considering the interests of Wikiversity as a collaborative project as the highest priority.

It is natural for people to assume that wiki "support staff" somehow have special control over the content of Wikimedia Foundation project wikis. There is actually a more subtle and interesting relationship between the special tasks that can be performed only by "[[Wikiversity:Support staff|Support staff]]" and the "real work" that is done by all wiki participants to actually develop the project. The term "custodian" was selected as the Wikiversity term for "sysop" partly in an attempt to stress the idea that it is not a very exciting position to hold. Picture custodians who quietly sweep the floor when a school is closed at the end of the day. My hope is that if we can do a good job of engineering the Wikiversity rules for support staff then it will be possible for custodians and bureaucrats to be almost invisible to the bulk of the community. Most wikiversity participants should be able to get on with the "real work" of the wiki and all they need to know is how to do is call a custodian in case a toilet blocks up and some mopping is needed. While we can strive to make "support staff" invisible, every action taken by wiki "support staff" needs to be open to review; if there is ever a problem caused by "support staff" then the community needs to be able to correct it. At Wikipedia there are occasionally calls for some kind of formal oversight for "support staff" such as periodic performance reviews. The system that has developed to deal with "support staff" problems is more adversarial and crisis-oriented. If someone perceives a problem with Wikipedia "support staff" then in order to correct it seems like there often has to be a formal and legalistic case brought before the arbitration committee. One way that "support staff" can get in the "dog house" is by trying to use their special tools to take control of wiki content. The bottom line is, "support staff" can only indirectly influence "respect of the academic world" by keeping a clean house within Wikiversity (cleaning up vandalism, etc). It is really up to "regular" Wikiversity participants to gain the respect of the academic world.

I have a few ideas which might be handy. I think it would be a good idea to aim for a document which we can expect to remain stable for say, a year or so. Wikiversity is still reasonably young, and I think planning ahead with a time horizon of around 12-16 months in mind is not too unreasonable. This might help us focus on having this page meet Wikiversity's current needs, while leaving the door open to flexibility as the editing environment changes. I think it might be easier to modify this draft if we discuss each section starting from top to bottom, with less emphasis between how the sections interrelate. Once we have done this, we can look at the resulting document as a whole to see if there are any inconsistencies between what is written and what our philosophies for the bureaucrat role should be. Roughly speaking, I think the discussions we had 4-5 months ago approached this page in the other direction, so it might be fruitful to try the another way. What is written so far seems reasonable. The concerns I have at the moment are primarily "semantic" - I think we need to clarify certain things. For example, in the first section, what does "well-trusted" really mean? How about the word "consensus"? Or "civility"? Let me focus on trust in this thread. I think there are two distinct notions here we should document - the first relates to bureaucratship, say, as an "administrative role", and the second relates to bureaucrat as a "representative role". In the former, the ideal bureaucrat is probably someone who generally interprets policy in such a way that maximizes consistency and minimizes surprise. That is, they act in a way which can be reasonably anticipated by the community. In the latter, the bureaucrat is someone who the community feels is a positive influence on Wikiversity, likely someone not particularly polarizing, with a well rounded knowledge of the site. The bureaucrat is someone who would be a good ambassador for Wikiversity. However, even this brief sketch seems problematic as it seems to open the door to a policy where the bureaucrat bit can be granted relatively liberally. This in itself is not problematic - it is the fact that it seems inconsistent with what I think the bureaucrat role is intended to be (a little more selective) which makes it so. What's the best way to proceed? Perhaps this sketch is really a non-issue, but I thought it might be a good idea just to write this down. We should probably aim for policy which balances these concerns nicely, so that its consequences are manageable by the community. Enough writing for now! I will try shorter tidbits next time. --[[User:HappyCamper|HappyCamper]] 22:23, 20 April 2007 (UTC) :"planning ahead with a time horizon of around 12-16 months in mind is not too unreasonable" <-- In your thinking, is it likely that this "time horizon" will include a real Wikiversity crisis in which the project might benefit from having a good set of bcrat guidelines in place, rather than the alternative of the community struggling through a crisis without the aid of good guidelines and then getting around to making useful policy only after the crisis is over? By "good guidelines " I mean that we would be able to learn from challenges that have previously been faced by other wiki projects.--[[User:JWSchmidt|JWSchmidt]] 23:38, 20 April 2007 (UTC) ::Learning from previous challenges on other projects - this sounds like a learning project in its own right. :-) I think it would be great to pursue such a project - but there's also an inevitability about us having to learn through this process ourselves in this (local) context. We will never be able to learn everything in advance - nor prepare for every inevitability - but we should endeavour to have as much of the process as clearly defined as possible, always leaving room for fresh and critical thinking, judgement, and reflexivity. Part of this is working through what terms like [[Wikiversity:Consensus|"consensus"]] mean - and these policies should be as clear as possible while also leaving flexibility for rethinking them in new light. For example, the notion of "reasonability" is fundamental to most legal systems, but what being "reasonable" is is a very complex notion. I don't think we need to recreate an entire legal system, but rather develop a model of consensus that will work for as long as it needs to. Wikiversity's development over a timeframe of 12-16 months sounds good as a thought experiment to start off with, however. :-) [[User:Cormaggio|Cormaggio]] <sup><small>[[User talk:Cormaggio|talk]]</small></sup> 00:29, 21 April 2007 (UTC) :::Well, 12-16 months is arbitrary. Ideally, it would be nice if we could come up with something that would be workable for all time, but that does not seem achievable. So, I just picked a number that was less than infinity...something which seems manageable (at least to me). Basically, a neat concept to suggest that we should not try and solve all the possible problems that might crop up. I didn't think of the phrase "thought experiment", but actually, that's a very nice way of putting it :-) I didn't have a potential Wikiversity crisis in mind when I wrote my previous post. I'll have to think about it, but maybe I'll offer an idea that perhaps a "crisis" on a Wiki generally turns policy into a source of polarization. :::Here's another metaphor which might be useful. Originally, I thought that policies here would develop sort of like growing plants from seeds. A little water and sunlight (ie. edits to the page) here and there...and obviously, watching the plant mature. But it seems this is developing more like a piece of artwork, say, chiseling a stone sculpture. Start with a rough draft, and work away at it to get something useful. :::I feel like I am going in circles, so maybe let's sketch out a bureaucrat I think would be healthy for Wikiversity, and how they might work. Obviously, this isn't the only sort of bureaucrat that would be useful for Wikiversity, but I'll describe one which is easiest for me to do right now. So, let's see...the bureaucrat will be just a normal editor on almost all pages on Wikiversity, with the exception of those directly related to creating custodians. They will not see custodianship as a too much of a political process. Policies will tend to be seen as descriptive, not prescriptive. Possibly a wikignome by nature. They will incline on promoting liberally - particular, for those users who seem to be dedicated to generating content on Wikiversity. The custodial bit is seen as a source of convenience for users, not as a source of autonomy. Possibly see Wikiversity more in an "eventualist" light instead of "immediatist" one (or whatever the neologism is). Promotions don't need to happen on fixed schedules.

For example, one of the key duties of bureaucrats is to turn wiki users into sysops (called [[Wikiversity:Custodianship|custodians]] at Wikiversity).

Bureaucrats are also the only local group capable of granting a user Bureaucrat status--the main purpose of this policy is to decide upon when they can and cannot do this. Among their other technical rights are the ability to rename local users and the ability to grant a user bot status. I think it very important that enwikiversity draft both a user renaming policy and a thorough [[Wikiversity:Bots|bot policy]], both of which we lack at the moment. *'''Non-technical rights''': On enwiki, we regard Bureaucrats as the ultimate judges of consensus--I believe we should maintain this idea in our Bureaucratship policy. Only bureacrats should be able to close requests for adminship and bureaucratship, approve or reject requests for name changes, and I would also like to propose that they be final authority in requests for bot status. While our focus here isn't a bot approvals process, I would suggest that we use a process similar to RfA for bot status, where users are granted bot status based upon community consensus and where the bureaucrats are the judges of this consensus. *'''What crats can't do although it's logical to think that they could''': Bureaucrats do not have the technically ability nor the authority to revoke ''any'' user status--crat, bot, or sysop. Requests for desysopping and the like must go through the [[m:Stewards]]. Note that this issue is truly not one that can be debated--'twas set in stone long ago due to a crat gone mad on enwiki. *'''Expectations of bureaucrats''': First and foremost, bureacrats must be well-trusted members of the community. They must have exceptional understanding of the way things work on Wikiversity and must be ''excellent'' judges of consensus. They must demonstrate through their extensive contributions to Wikiversity that they are not rash in decision-making nor incivil nor incompetent. Also of primary importance is a bureaucrat's ability to thoroughly explain and defend the decisions or he or she makes as well the ability to admit fault.

In theory, all custodianship "elections" should actually be ''discussions'' where the goal is attaining consensus, in which case the bureaucrat should then be required to not just look at numbers of supporters vs. opposers, but rather to thoroughly read through the discussion and determine what the true ''consensus'' of the community is. Nonetheless, that is often an idealist concept, and it may be a methodology that we will not be able to maintain for long. In any case, however, I belive that, though adminship is truly not a big deal, if ''one third'' or more of the community has good reason to oppose handing someone the mop, that person should not be made an admin--I would personally favor a much higher level of needed support (75-80%) before a Bureaucrat even considers making a user an admin. Codifying consensus clearly has its benefits--it spares crats a lot of work if they just have to look at numbers and it gives them an easy way to respond to disputes that arise about their actions, by simply citing numbers. But it is not the wiki way, nor should the task of bureaucrats simply be to count votes. I rather believe the most important quality of a prospective bureaucrat to be the ability to reasonably judge ''consensus'' without counting votes, the ability to make tough decisions, and the ability to adequately to defend oneself when making such decisions. That, I belive, should be our focus, rather than deciding what percentage of support constitutes consensus in all situations. Do keep in mind that [[m:Polling is evil]] and should be avoided where possible. Now to address Daanschr's concerns that "the ones who create the articles are not the ones who make the decisions"--I personally believe it best so; the major article writers tend to be the ones least concerned with administrivia such as blocking policies and deletion policies and the tedious boring tasks of clearing categories such as [[w:CAT:NSD]]. The job of an administrator is to be well-versed in policy matters, to have excellent common sense, and to serve as diplomats in disputes--while writing featured articles is an excellent way to gain knowledge in how to deal with disputes, it is by far not the only way, and I find that the major article writers tend to be the least capable of maintaining neutrality. Note as well that administrative permissions provide you, in theory at least, with no higher status in the community, no more influence in policy matters, and certainly not any extra tools to help you write better articles. Administrators are just that--administrators; they deal with administrative issues. Similarly, Bureaucrats deal with bureaucratic issues such as renaming users, flagging bots, and processing requests for adminship. Neither admins nor bureaucrats nor checkusers nor any other user group should have any greater influence over individual articles nor the policies governing all users and articles than any other user. Okay, ending babbling now. :D [[User:AmiDaniel|AmiDaniel]] ([[User talk:AmiDaniel|talk]]) 18:01, 10 December 2006 (UTC) :I don't like the idea of always trying to get consensus. The result of this is unending discussions on policy and a conservative, defensive community. I would prefer to have a system which can be able to changed things. Such a system could be top-down with a clear leader, who can make tough decisions, a kind of democratic system where majorities can overrule minorities, or a corporate system where institutes within Wikiversity can have a say on policy.

Sure, it takes longer, but I find the results tend to be much more beneficial. Note as well that by consensus I don't mean that everyone has to agree upon something for it to be done, but rather that decisions should be made by the community as a whole rather than just a handful of individuals, or even a narrow majority of the community.

The best means to maintaining the motivation and participation of all involved in a wiki is to recognise that there is often a diversity of points of view, and that this diversity needs to be reflected in the consensus-of-the-time (which can itself be discussed and changed). We have to recognise that individuals bring particular viewpoints to the community, and that individuals have needs in terms of being heard, being valued etc. So we must place some value in individualism. But we are also here to create a collaborative project - which means we need to be able to listen to one another, discuss openly, and sometimes take criticism.

Anyone claiming to be able to accurately judge the "consensus" of a large group discussion without some kind of a straw poll .... Further, it is unlikely that a large fraction of participants at wikiversity will actually care enough about who operates the mops to participate repeatedly in "consensus" building. Sometimes, temporary closure can be a beautiful thing. I think initially most administrative functions, including bureaucrat status, should be fairly easily attained and moderately easily removed if people so trusted cannot learn to wield their priveleges/responsibilities effectively. This was the case when Wikipedia was a startup and helped grow the community and encyclopedia to critical mass. Of course, Wikipedia had a formal clearcut organizational structure that was fairly flat. There was the God King, the developers, everyone else. Adminship was essentially the result of having sufficient experience with the wiki and the community to be trusted to avoid really foolish blunders and trusted to be willing to help fix mistakes. At the moment Wikiversity is vertically taller than early Wikipedia was by approximately a Board of Directors, a committee, and possibly an informal subcommittee, stewards and bureaurcrats and custodians. Custodianship is not automatic after an initial introduction period. Anybody think this tall fuzzy infrastructure is helpful in retaining newcomers? How could we emulate the early structure of Wikipedia? Well perhaps once a year we could have a vote for an honorary "God King" who could occasionally decide tough issues for the community (those urgently requiring dramatic prompt action for the greater good or at least to avoid the greater bad ...) but usually keep quiet and let the community argue it out. Obviously our "God King" would not have the real authority that Jimbo started out with and has carefully preserved by stacking the Wikimedia Foundation board .... still I expect the Board (or a committee or a steward or a local bureaucrat or a local participant) might listen carefully when the honorary Wikiversity God King speaks regarding Wikiversity issues considering the position as a community spokesperson has been numerically substantiated by a majority of the votes cast determined legitimate and counted. Perhaps we should include term limits or restrict the candidates to former bureaucrats??? Notice that if you consider voting evil that can dramatically reduce the voting. One vote once a year and then the God King can help sort it all out by deciding the "consensus". No further straw polls required, unless of course the God King requests one.

A wiki bureaucrat should have a good understanding of the mission of the wiki and a willingness to put the success of the project ahead of consensus. Bureaucrats are in a position to do so by '''not''' acting when they are asked to act. If a bureaucrat feels that a requested action would do more harm than good, the bureaucrat can discuss the requested action before acting. "[[w:Ochlocracy|Mob rule]]" is a potential danger in any human social system that is guided by consensus. Bureaucrats can function as a check on this danger. Bureaucrats should be experienced wiki users who are always watching for situations in which the community might be rushing into a poor decision that does not really serve the long-term interests of the project. Also, too close adherence to policy can create problems. For example, if on the last scheduled day of a community discussion some new evidence is provided, it might be wise to extend the discussion rather than close it at the scheduled time. When bureaucrats are willing to do what is best for the project '''and''' explain what they are doing it can allow the community to be thoughtful and possibly avoid rushing into a regrettable course of action. Item #4 in the list (acting without consensus, above) is a bit trickier than failure to act. When bureaucrats feel forced into taking action in the absence of community consensus there should at least be consensus among bureaucrats and a clear explanation to the community of why the action is being taken. It makes sense to me that any bureaucrat action that is not supported by prior community consensus should be open to critical evaluation by the community. There was an interesting case at the English Wikipedia in which bureaucrats "broke the rules" in deciding to grant adminship to a candidate who had an unusually low level of community support. I think the Wikiversity community needs to give some thought to the best way to deal with that kind of situation. --[[User:JWSchmidt|JWSchmidt]] 19:47, 10 December 2006 (UTC) :If precedent needs to be made, the bureaucrat better be in a position to justify this rigorously.

Even consensus amongst bureaucrats is not enough excuse.----[[User:Hillgentleman|Hillgentleman]]|[[User talk:hillgentleman|Talk]] 23:23, 10 December 2006 (UTC) ::I suppose we could make a list of everything that can "trump" community consensus. For example, sometimes the Wikimedia Foundation central office makes a sudden decision (such as deleting a wiki page or placing an editing ban on an individual) based on the need to protect the Foundation from legal attack or threats of legal attack. Also, there are some standing Wikimedia Foundation policies that pertain to all Wikimedia Foundation projects. I do not think we can expect a bureaucrat to simply bow to community consensus if the bureaucrat knows that there is a good reason not to initiate an action called for by a community discussion. Simply put, it is possible for community consensus to fail to identify the best course of action and it is not reasonable to tell bureaucrats that they must '''always''' do what community consensus calls for. This is similar to saying that a soldier follows orders but does have to follow an order that involves doing something illegal. However, such situations where a bureaucrat might contradict community consensus are extraordinary. For the vast majority of bureaucrat actions there is no conflict with community consensus or likelihood that anyone would ever question the action. --[[User:JWSchmidt|JWSchmidt]] 02:44, 11 December 2006 (UTC) :::I agree with JWSchmidt that the interest of Wikiversity should be above the interest of single individuals who damage the whole project.

The community can always appeal the the higher hiearchy to activate some additional bureaucrats with diverse views if a cabal of consistently agreeing bureaucrats seem to consistently take action opposing the "consensus" of the rest of the Wikiversity community within the scope of discussion. (I assume literature students will not be interested in dictating how engineering sections implement local java labs for finite element analysis ... unless it effects their online response from Wikimedia servers.) Just as the rest of the community participants can bow out at will and go do something else. We probably should define what "consensus" means locally. Some people seem to mean a simple majority while others seem to hold out for unanimous and yet others prefer a fuzzy definition preserving the bureaucrats independence and ability to summarize and act as they see fit. Meanwhile, the "voting is evil" faction seems to prefer guessing while my own "voting is ok" faction prefers concise quantitative data summarizing the final instantaneous result of the discussions.

More often than not it ends up consisting of an evaluation of a user's entire history of contributions rather than their fitness for adminship. This is partially due to the fact that at most other projects there's usually no concrete experience with the user exercising admin features prior to the RfA. So the community is forced to use other points of reference to evaluate the candidate. At Wikiversity, we've created a process that's different from that. Candidates for custodianship are required to be mentored for four weeks, after which they are evaluated by their mentor. The point of this process is for a candidate to have the opportunity to exercise custodian tools and demonstrate the way in which they would conduct themselves as full custodians. If the mentor provides a favorable recommendation, the candidate can apply for full custodianship, subject to community discussion. The final decision in this matter lies with the bureaucrats who are expected to evaluate the mentorship period, the recommendation and community feedback. It's not so much a question of consensus but of informed decision-making considering the interests of Wikiversity as a collaborative project as the highest priority. For other issues, I would expect for bureaucrats to act in the same thoughtful and constructive manner. [[User:sebmol|sebmol]] [[User talk:sebmol|<sup>?</sup>]] 16:49, 11 December 2006 (UTC) :"trying to gain the respect of the academic world" <-- I think many people outside of the wiki world are baffled by how wikis function. It is natural for people to assume that wiki "support staff" somehow have special control over the content of Wikimedia Foundation project wikis. There is actually a more subtle and interesting relationship between the special tasks that can be performed only by "[[Wikiversity:Support staff|Support staff]]" and the "real work" that is done by all wiki participants to actually develop the project. The term "custodian" was selected as the Wikiversity term for "sysop" partly in an attempt to stress the idea that it is not a very exciting position to hold. Picture custodians who quietly sweep the floor when a school is closed at the end of the day. My hope is that if we can do a good job of engineering the Wikiversity rules for support staff then it will be possible for custodians and bureaucrats to be almost invisible to the bulk of the community. Most wikiversity participants should be able to get on with the "real work" of the wiki and all they need to know is how to do is call a custodian in case a toilet blocks up and some mopping is needed. While we can strive to make "support staff" invisible, every action taken by wiki "support staff" needs to be open to review; if there is ever a problem caused by "support staff" then the community needs to be able to correct it. At Wikipedia there are occasionally calls for some kind of formal oversight for "support staff" such as periodic performance reviews. The system that has developed to deal with "support staff" problems is more adversarial and crisis-oriented. If someone perceives a problem with Wikipedia "support staff" then in order to correct it seems like there often has to be a formal and legalistic case brought before the arbitration committee. One way that "support staff" can get in the "dog house" is by trying to use their special tools to take control of wiki content. The bottom line is, "support staff" can only indirectly influence "respect of the academic world" by keeping a clean house within Wikiversity (cleaning up vandalism, etc). It is really up to "regular" Wikiversity participants to gain the respect of the academic world. However, it may be useful for Wikiversity to create a new type of "functionary" that can specialize for "professional" contacts with the academic world.

I have a few ideas which might be handy. I think it would be a good idea to aim for a document which we can expect to remain stable for say, a year or so. Wikiversity is still reasonably young, and I think planning ahead with a time horizon of around 12-16 months in mind is not too unreasonable. This might help us focus on having this page meet Wikiversity's current needs, while leaving the door open to flexibility as the editing environment changes. I think it might be easier to modify this draft if we discuss each section starting from top to bottom, with less emphasis between how the sections interrelate. Once we have done this, we can look at the resulting document as a whole to see if there are any inconsistencies between what is written and what our philosophies for the bureaucrat role should be. Roughly speaking, I think the discussions we had 4-5 months ago approached this page in the other direction, so it might be fruitful to try the another way. What is written so far seems reasonable. The concerns I have at the moment are primarily "semantic" - I think we need to clarify certain things. For example, in the first section, what does "well-trusted" really mean? How about the word "consensus"? Or "civility"? Let me focus on trust in this thread. I think there are two distinct notions here we should document - the first relates to bureaucratship, say, as an "administrative role", and the second relates to bureaucrat as a "representative role". In the former, the ideal bureaucrat is probably someone who generally interprets policy in such a way that maximizes consistency and minimizes surprise. That is, they act in a way which can be reasonably anticipated by the community. In the latter, the bureaucrat is someone who the community feels is a positive influence on Wikiversity, likely someone not particularly polarizing, with a well rounded knowledge of the site. The bureaucrat is someone who would be a good ambassador for Wikiversity. However, even this brief sketch seems problematic as it seems to open the door to a policy where the bureaucrat bit can be granted relatively liberally. This in itself is not problematic - it is the fact that it seems inconsistent with what I think the bureaucrat role is intended to be (a little more selective) which makes it so. What's the best way to proceed? Perhaps this sketch is really a non-issue, but I thought it might be a good idea just to write this down. We should probably aim for policy which balances these concerns nicely, so that its consequences are manageable by the community. Enough writing for now! I will try shorter tidbits next time. --[[User:HappyCamper|HappyCamper]] 22:23, 20 April 2007 (UTC) :"planning ahead with a time horizon of around 12-16 months in mind is not too unreasonable" <-- In your thinking, is it likely that this "time horizon" will include a real Wikiversity crisis in which the project might benefit from having a good set of bcrat guidelines in place, rather than the alternative of the community struggling through a crisis without the aid of good guidelines and then getting around to making useful policy only after the crisis is over?

We will never be able to learn everything in advance - nor prepare for every inevitability - but we should endeavour to have as much of the process as clearly defined as possible, always leaving room for fresh and critical thinking, judgement, and reflexivity. Part of this is working through what terms like [[Wikiversity:Consensus|"consensus"]] mean - and these policies should be as clear as possible while also leaving flexibility for rethinking them in new light. For example, the notion of "reasonability" is fundamental to most legal systems, but what being "reasonable" is is a very complex notion. I don't think we need to recreate an entire legal system, but rather develop a model of consensus that will work for as long as it needs to.

So, let's see...the bureaucrat will be just a normal editor on almost all pages on Wikiversity, with the exception of those directly related to creating custodians.

For example, one of the key duties of bureaucrats is to turn wiki users into sysops (called [[Wikiversity:Custodianship|custodians]] at Wikiversity). The Wikiversity community should decide if there is some set level of community support required for custodianship or if bureaucrats can exercise some discretion at the end of a community discussion about a candidate for custodianship. --[[User:JWSchmidt|JWSchmidt]] 23:39, 7 December 2006 (UTC) == Responsibilities of bureaucrats == Well, before we can really begin drafting this policy, I think we first need to take a comprehensive look at the technical rights of bureaucrats, the "non-technical" rights of bureaucrats, and the responsibilities of bureaucrats on enwikiversity. *'''Technical rigts''': To get the obvious out of the way: bureaucrats are the only local user group capable of granting a user SysOp rights--the policy of when this permission can be used is covered (to some extent) in [[Wikiversity:Custodianship]], so I'm not sure this policy will need to elaborate much upon this. Bureaucrats are also the only local group capable of granting a user Bureaucrat status--the main purpose of this policy is to decide upon when they can and cannot do this. Among their other technical rights are the ability to rename local users and the ability to grant a user bot status. I think it very important that enwikiversity draft both a user renaming policy and a thorough [[Wikiversity:Bots|bot policy]], both of which we lack at the moment. *'''Non-technical rights''': On enwiki, we regard Bureaucrats as the ultimate judges of consensus--I believe we should maintain this idea in our Bureaucratship policy. Only bureacrats should be able to close requests for adminship and bureaucratship, approve or reject requests for name changes, and I would also like to propose that they be final authority in requests for bot status. While our focus here isn't a bot approvals process, I would suggest that we use a process similar to RfA for bot status, where users are granted bot status based upon community consensus and where the bureaucrats are the judges of this consensus. *'''What crats can't do although it's logical to think that they could''': Bureaucrats do not have the technically ability nor the authority to revoke ''any'' user status--crat, bot, or sysop. Requests for desysopping and the like must go through the [[m:Stewards]]. Note that this issue is truly not one that can be debated--'twas set in stone long ago due to a crat gone mad on enwiki. *'''Expectations of bureaucrats''': First and foremost, bureacrats must be well-trusted members of the community. They must have exceptional understanding of the way things work on Wikiversity and must be ''excellent'' judges of consensus. They must demonstrate through their extensive contributions to Wikiversity that they are not rash in decision-making nor incivil nor incompetent. Also of primary importance is a bureaucrat's ability to thoroughly explain and defend the decisions or he or she makes as well the ability to admit fault.

In theory, all custodianship "elections" should actually be ''discussions'' where the goal is attaining consensus, in which case the bureaucrat should then be required to not just look at numbers of supporters vs. opposers, but rather to thoroughly read through the discussion and determine what the true ''consensus'' of the community is. Nonetheless, that is often an idealist concept, and it may be a methodology that we will not be able to maintain for long. In any case, however, I belive that, though adminship is truly not a big deal, if ''one third'' or more of the community has good reason to oppose handing someone the mop, that person should not be made an admin--I would personally favor a much higher level of needed support (75-80%) before a Bureaucrat even considers making a user an admin. Codifying consensus clearly has its benefits--it spares crats a lot of work if they just have to look at numbers and it gives them an easy way to respond to disputes that arise about their actions, by simply citing numbers. But it is not the wiki way, nor should the task of bureaucrats simply be to count votes. I rather believe the most important quality of a prospective bureaucrat to be the ability to reasonably judge ''consensus'' without counting votes, the ability to make tough decisions, and the ability to adequately to defend oneself when making such decisions. That, I belive, should be our focus, rather than deciding what percentage of support constitutes consensus in all situations. Do keep in mind that [[m:Polling is evil]] and should be avoided where possible. Now to address Daanschr's concerns that "the ones who create the articles are not the ones who make the decisions"--I personally believe it best so; the major article writers tend to be the ones least concerned with administrivia such as blocking policies and deletion policies and the tedious boring tasks of clearing categories such as [[w:CAT:NSD]]. The job of an administrator is to be well-versed in policy matters, to have excellent common sense, and to serve as diplomats in disputes--while writing featured articles is an excellent way to gain knowledge in how to deal with disputes, it is by far not the only way, and I find that the major article writers tend to be the least capable of maintaining neutrality. Note as well that administrative permissions provide you, in theory at least, with no higher status in the community, no more influence in policy matters, and certainly not any extra tools to help you write better articles. Administrators are just that--administrators; they deal with administrative issues. Similarly, Bureaucrats deal with bureaucratic issues such as renaming users, flagging bots, and processing requests for adminship. Neither admins nor bureaucrats nor checkusers nor any other user group should have any greater influence over individual articles nor the policies governing all users and articles than any other user. Okay, ending babbling now. :D [[User:AmiDaniel|AmiDaniel]] ([[User talk:AmiDaniel|talk]]) 18:01, 10 December 2006 (UTC) :I don't like the idea of always trying to get consensus. The result of this is unending discussions on policy and a conservative, defensive community. I would prefer to have a system which can be able to changed things. Such a system could be top-down with a clear leader, who can make tough decisions, a kind of democratic system where majorities can overrule minorities, or a corporate system where institutes within Wikiversity can have a say on policy.

Sure, it takes longer, but I find the results tend to be much more beneficial. Note as well that by consensus I don't mean that everyone has to agree upon something for it to be done, but rather that decisions should be made by the community as a whole rather than just a handful of individuals, or even a narrow majority of the community.

The best means to maintaining the motivation and participation of all involved in a wiki is to recognise that there is often a diversity of points of view, and that this diversity needs to be reflected in the consensus-of-the-time (which can itself be discussed and changed). We have to recognise that individuals bring particular viewpoints to the community, and that individuals have needs in terms of being heard, being valued etc. So we must place some value in individualism. But we are also here to create a collaborative project - which means we need to be able to listen to one another, discuss openly, and sometimes take criticism. All of this applies to anyone - including custodians and bureaucrats. But we can't give up our base of consensus - otherwise it would not be a truly collaborative project.

Anyone claiming to be able to accurately judge the "consensus" of a large group discussion without some kind of a straw poll .... Further, it is unlikely that a large fraction of participants at wikiversity will actually care enough about who operates the mops to participate repeatedly in "consensus" building. Sometimes, temporary closure can be a beautiful thing. I think initially most administrative functions, including bureaucrat status, should be fairly easily attained and moderately easily removed if people so trusted cannot learn to wield their priveleges/responsibilities effectively. This was the case when Wikipedia was a startup and helped grow the community and encyclopedia to critical mass. Of course, Wikipedia had a formal clearcut organizational structure that was fairly flat. There was the God King, the developers, everyone else. Adminship was essentially the result of having sufficient experience with the wiki and the community to be trusted to avoid really foolish blunders and trusted to be willing to help fix mistakes. At the moment Wikiversity is vertically taller than early Wikipedia was by approximately a Board of Directors, a committee, and possibly an informal subcommittee, stewards and bureaurcrats and custodians. Custodianship is not automatic after an initial introduction period. Anybody think this tall fuzzy infrastructure is helpful in retaining newcomers? How could we emulate the early structure of Wikipedia? Well perhaps once a year we could have a vote for an honorary "God King" who could occasionally decide tough issues for the community (those urgently requiring dramatic prompt action for the greater good or at least to avoid the greater bad ...) but usually keep quiet and let the community argue it out. Obviously our "God King" would not have the real authority that Jimbo started out with and has carefully preserved by stacking the Wikimedia Foundation board .... still I expect the Board (or a committee or a steward or a local bureaucrat or a local participant) might listen carefully when the honorary Wikiversity God King speaks regarding Wikiversity issues considering the position as a community spokesperson has been numerically substantiated by a majority of the votes cast determined legitimate and counted. Perhaps we should include term limits or restrict the candidates to former bureaucrats??? Notice that if you consider voting evil that can dramatically reduce the voting. One vote once a year and then the God King can help sort it all out by deciding the "consensus". No further straw polls required, unless of course the God King requests one.

Consensus isn't that hard to ascertain - if there is opposition, it will be clear on the relevant pages. If needs be, polls can certainly be used to gauge opinion. But I think you're misinterpreting the gist of the maxim "voting/polls is/are evil", which should really read something like: "Votes/polls can be divisive, and they should be used sparingly, with caution, and after substantial discussion, and their results should not be taken as necessarily indicating a majority or a consensus within the community".

A wiki bureaucrat should have a good understanding of the mission of the wiki and a willingness to put the success of the project ahead of consensus. Bureaucrats are in a position to do so by '''not''' acting when they are asked to act. If a bureaucrat feels that a requested action would do more harm than good, the bureaucrat can discuss the requested action before acting. "[[w:Ochlocracy|Mob rule]]" is a potential danger in any human social system that is guided by consensus. Bureaucrats can function as a check on this danger. Bureaucrats should be experienced wiki users who are always watching for situations in which the community might be rushing into a poor decision that does not really serve the long-term interests of the project. Also, too close adherence to policy can create problems. For example, if on the last scheduled day of a community discussion some new evidence is provided, it might be wise to extend the discussion rather than close it at the scheduled time. When bureaucrats are willing to do what is best for the project '''and''' explain what they are doing it can allow the community to be thoughtful and possibly avoid rushing into a regrettable course of action. Item #4 in the list (acting without consensus, above) is a bit trickier than failure to act. When bureaucrats feel forced into taking action in the absence of community consensus there should at least be consensus among bureaucrats and a clear explanation to the community of why the action is being taken. It makes sense to me that any bureaucrat action that is not supported by prior community consensus should be open to critical evaluation by the community. There was an interesting case at the English Wikipedia in which bureaucrats "broke the rules" in deciding to grant adminship to a candidate who had an unusually low level of community support. I think the Wikiversity community needs to give some thought to the best way to deal with that kind of situation. --[[User:JWSchmidt|JWSchmidt]] 19:47, 10 December 2006 (UTC) :If precedent needs to be made, the bureaucrat better be in a position to justify this rigorously.

For example, sometimes the Wikimedia Foundation central office makes a sudden decision (such as deleting a wiki page or placing an editing ban on an individual) based on the need to protect the Foundation from legal attack or threats of legal attack. Also, there are some standing Wikimedia Foundation policies that pertain to all Wikimedia Foundation projects. I do not think we can expect a bureaucrat to simply bow to community consensus if the bureaucrat knows that there is a good reason not to initiate an action called for by a community discussion. Simply put, it is possible for community consensus to fail to identify the best course of action and it is not reasonable to tell bureaucrats that they must '''always''' do what community consensus calls for. This is similar to saying that a soldier follows orders but does have to follow an order that involves doing something illegal. However, such situations where a bureaucrat might contradict community consensus are extraordinary. For the vast majority of bureaucrat actions there is no conflict with community consensus or likelihood that anyone would ever question the action. --[[User:JWSchmidt|JWSchmidt]] 02:44, 11 December 2006 (UTC) :::I agree with JWSchmidt that the interest of Wikiversity should be above the interest of single individuals who damage the whole project.

(I assume literature students will not be interested in dictating how engineering sections implement local java labs for finite element analysis ... unless it effects their online response from Wikimedia servers.) Just as the rest of the community participants can bow out at will and go do something else. We probably should define what "consensus" means locally. Some people seem to mean a simple majority while others seem to hold out for unanimous and yet others prefer a fuzzy definition preserving the bureaucrats independence and ability to summarize and act as they see fit.

[[User:Cormaggio|Cormaggio]] <sup><small>[[User talk:Cormaggio|talk]]</small></sup> 14:47, 11 December 2006 (UTC) For instance how the policy of [[Wikiversity:Cite sources|citing]] and [[Wikiversity:Verifiability|verifying]] [[Wikiversity:Reliable sources|reliable sources]] can be implemented. But also how [[Learning to learn a wiki way]], [[Wikiversity:Scholarly ethics|Scholarly Ethics]] or my idea of trying to gain the respect of the academic world can be implemented. This can also be decided for at school level, so each school can determine for itself on how to use it or by not using it at all. Happycamper, i quess the stewarts of the Wikimedia Foundation are still in charge here. When a bureaucrat behaves in such a way that it damages the community considerably, then the stewarts can interphere isn't it? It would be funny if that is the case.

More often than not it ends up consisting of an evaluation of a user's entire history of contributions rather than their fitness for adminship. This is partially due to the fact that at most other projects there's usually no concrete experience with the user exercising admin features prior to the RfA. So the community is forced to use other points of reference to evaluate the candidate. At Wikiversity, we've created a process that's different from that. Candidates for custodianship are required to be mentored for four weeks, after which they are evaluated by their mentor. The point of this process is for a candidate to have the opportunity to exercise custodian tools and demonstrate the way in which they would conduct themselves as full custodians. If the mentor provides a favorable recommendation, the candidate can apply for full custodianship, subject to community discussion. The final decision in this matter lies with the bureaucrats who are expected to evaluate the mentorship period, the recommendation and community feedback. It's not so much a question of consensus but of informed decision-making considering the interests of Wikiversity as a collaborative project as the highest priority. For other issues, I would expect for bureaucrats to act in the same thoughtful and constructive manner. [[User:sebmol|sebmol]] [[User talk:sebmol|<sup>?</sup>]] 16:49, 11 December 2006 (UTC) :"trying to gain the respect of the academic world" <-- I think many people outside of the wiki world are baffled by how wikis function. It is natural for people to assume that wiki "support staff" somehow have special control over the content of Wikimedia Foundation project wikis. There is actually a more subtle and interesting relationship between the special tasks that can be performed only by "[[Wikiversity:Support staff|Support staff]]" and the "real work" that is done by all wiki participants to actually develop the project. The term "custodian" was selected as the Wikiversity term for "sysop" partly in an attempt to stress the idea that it is not a very exciting position to hold. Picture custodians who quietly sweep the floor when a school is closed at the end of the day. My hope is that if we can do a good job of engineering the Wikiversity rules for support staff then it will be possible for custodians and bureaucrats to be almost invisible to the bulk of the community. Most wikiversity participants should be able to get on with the "real work" of the wiki and all they need to know is how to do is call a custodian in case a toilet blocks up and some mopping is needed. While we can strive to make "support staff" invisible, every action taken by wiki "support staff" needs to be open to review; if there is ever a problem caused by "support staff" then the community needs to be able to correct it. At Wikipedia there are occasionally calls for some kind of formal oversight for "support staff" such as periodic performance reviews. The system that has developed to deal with "support staff" problems is more adversarial and crisis-oriented. If someone perceives a problem with Wikipedia "support staff" then in order to correct it seems like there often has to be a formal and legalistic case brought before the arbitration committee. One way that "support staff" can get in the "dog house" is by trying to use their special tools to take control of wiki content. The bottom line is, "support staff" can only indirectly influence "respect of the academic world" by keeping a clean house within Wikiversity (cleaning up vandalism, etc). It is really up to "regular" Wikiversity participants to gain the respect of the academic world. However, it may be useful for Wikiversity to create a new type of "functionary" that can specialize for "professional" contacts with the academic world. There are some ideas along this line [[Wikiversity:Review board#Ambassadorial function|here]]. --[[User:JWSchmidt|JWSchmidt]] 17:37, 11 December 2006 (UTC) ::If the scholarly ethics will be enforced by the support staff, then their roll will not be invisible.

Bureaucrats and custodians should not get involved ''in their capacities as support staff'' in the implementation of such policies - they should get involved in discussing such policies and applying them as completely equal community members. As far as I can see it, the only policies that would be of direct relevance to a bureaucrat's or custodian's position would be those around civility - and even then, it is still a ''community'' issue, to perhaps be implemented by a member of the "support staff".

I have a few ideas which might be handy. I think it would be a good idea to aim for a document which we can expect to remain stable for say, a year or so. Wikiversity is still reasonably young, and I think planning ahead with a time horizon of around 12-16 months in mind is not too unreasonable. This might help us focus on having this page meet Wikiversity's current needs, while leaving the door open to flexibility as the editing environment changes. I think it might be easier to modify this draft if we discuss each section starting from top to bottom, with less emphasis between how the sections interrelate. Once we have done this, we can look at the resulting document as a whole to see if there are any inconsistencies between what is written and what our philosophies for the bureaucrat role should be. Roughly speaking, I think the discussions we had 4-5 months ago approached this page in the other direction, so it might be fruitful to try the another way. What is written so far seems reasonable. The concerns I have at the moment are primarily "semantic" - I think we need to clarify certain things. For example, in the first section, what does "well-trusted" really mean? How about the word "consensus"? Or "civility"? Let me focus on trust in this thread. I think there are two distinct notions here we should document - the first relates to bureaucratship, say, as an "administrative role", and the second relates to bureaucrat as a "representative role". In the former, the ideal bureaucrat is probably someone who generally interprets policy in such a way that maximizes consistency and minimizes surprise. That is, they act in a way which can be reasonably anticipated by the community. In the latter, the bureaucrat is someone who the community feels is a positive influence on Wikiversity, likely someone not particularly polarizing, with a well rounded knowledge of the site. The bureaucrat is someone who would be a good ambassador for Wikiversity. However, even this brief sketch seems problematic as it seems to open the door to a policy where the bureaucrat bit can be granted relatively liberally. This in itself is not problematic - it is the fact that it seems inconsistent with what I think the bureaucrat role is intended to be (a little more selective) which makes it so. What's the best way to proceed? Perhaps this sketch is really a non-issue, but I thought it might be a good idea just to write this down. We should probably aim for policy which balances these concerns nicely, so that its consequences are manageable by the community. Enough writing for now! I will try shorter tidbits next time. --[[User:HappyCamper|HappyCamper]] 22:23, 20 April 2007 (UTC) :"planning ahead with a time horizon of around 12-16 months in mind is not too unreasonable" <-- In your thinking, is it likely that this "time horizon" will include a real Wikiversity crisis in which the project might benefit from having a good set of bcrat guidelines in place, rather than the alternative of the community struggling through a crisis without the aid of good guidelines and then getting around to making useful policy only after the crisis is over? By "good guidelines " I mean that we would be able to learn from challenges that have previously been faced by other wiki projects.--[[User:JWSchmidt|JWSchmidt]] 23:38, 20 April 2007 (UTC) ::Learning from previous challenges on other projects - this sounds like a learning project in its own right. :-) I think it would be great to pursue such a project - but there's also an inevitability about us having to learn through this process ourselves in this (local) context. We will never be able to learn everything in advance - nor prepare for every inevitability - but we should endeavour to have as much of the process as clearly defined as possible, always leaving room for fresh and critical thinking, judgement, and reflexivity. Part of this is working through what terms like [[Wikiversity:Consensus|"consensus"]] mean - and these policies should be as clear as possible while also leaving flexibility for rethinking them in new light. For example, the notion of "reasonability" is fundamental to most legal systems, but what being "reasonable" is is a very complex notion. I don't think we need to recreate an entire legal system, but rather develop a model of consensus that will work for as long as it needs to. Wikiversity's development over a timeframe of 12-16 months sounds good as a thought experiment to start off with, however. :-) [[User:Cormaggio|Cormaggio]] <sup><small>[[User talk:Cormaggio|talk]]</small></sup> 00:29, 21 April 2007 (UTC) :::Well, 12-16 months is arbitrary.

Basically, a neat concept to suggest that we should not try and solve all the possible problems that might crop up. I didn't think of the phrase "thought experiment", but actually, that's a very nice way of putting it :-) I didn't have a potential Wikiversity crisis in mind when I wrote my previous post. I'll have to think about it, but maybe I'll offer an idea that perhaps a "crisis" on a Wiki generally turns policy into a source of polarization. :::Here's another metaphor which might be useful. Originally, I thought that policies here would develop sort of like growing plants from seeds.

Obviously, this isn't the only sort of bureaucrat that would be useful for Wikiversity, but I'll describe one which is easiest for me to do right now. So, let's see...the bureaucrat will be just a normal editor on almost all pages on Wikiversity, with the exception of those directly related to creating custodians. They will not see custodianship as a too much of a political process. Policies will tend to be seen as descriptive, not prescriptive. Possibly a wikignome by nature. They will incline on promoting liberally - particular, for those users who seem to be dedicated to generating content on Wikiversity. The custodial bit is seen as a source of convenience for users, not as a source of autonomy. Possibly see Wikiversity more in an "eventualist" light instead of "immediatist" one (or whatever the neologism is). Promotions don't need to happen on fixed schedules.

Bureaucrats are also the only local group capable of granting a user Bureaucrat status--the main purpose of this policy is to decide upon when they can and cannot do this. Among their other technical rights are the ability to rename local users and the ability to grant a user bot status. I think it very important that enwikiversity draft both a user renaming policy and a thorough [[Wikiversity:Bots|bot policy]], both of which we lack at the moment. *'''Non-technical rights''': On enwiki, we regard Bureaucrats as the ultimate judges of consensus--I believe we should maintain this idea in our Bureaucratship policy. Only bureacrats should be able to close requests for adminship and bureaucratship, approve or reject requests for name changes, and I would also like to propose that they be final authority in requests for bot status. While our focus here isn't a bot approvals process, I would suggest that we use a process similar to RfA for bot status, where users are granted bot status based upon community consensus and where the bureaucrats are the judges of this consensus. *'''What crats can't do although it's logical to think that they could''': Bureaucrats do not have the technically ability nor the authority to revoke ''any'' user status--crat, bot, or sysop. Requests for desysopping and the like must go through the [[m:Stewards]]. Note that this issue is truly not one that can be debated--'twas set in stone long ago due to a crat gone mad on enwiki. *'''Expectations of bureaucrats''': First and foremost, bureacrats must be well-trusted members of the community. They must have exceptional understanding of the way things work on Wikiversity and must be ''excellent'' judges of consensus. They must demonstrate through their extensive contributions to Wikiversity that they are not rash in decision-making nor incivil nor incompetent. Also of primary importance is a bureaucrat's ability to thoroughly explain and defend the decisions or he or she makes as well the ability to admit fault.

In theory, all custodianship "elections" should actually be ''discussions'' where the goal is attaining consensus, in which case the bureaucrat should then be required to not just look at numbers of supporters vs. opposers, but rather to thoroughly read through the discussion and determine what the true ''consensus'' of the community is. Nonetheless, that is often an idealist concept, and it may be a methodology that we will not be able to maintain for long. In any case, however, I belive that, though adminship is truly not a big deal, if ''one third'' or more of the community has good reason to oppose handing someone the mop, that person should not be made an admin--I would personally favor a much higher level of needed support (75-80%) before a Bureaucrat even considers making a user an admin. Codifying consensus clearly has its benefits--it spares crats a lot of work if they just have to look at numbers and it gives them an easy way to respond to disputes that arise about their actions, by simply citing numbers. But it is not the wiki way, nor should the task of bureaucrats simply be to count votes. I rather believe the most important quality of a prospective bureaucrat to be the ability to reasonably judge ''consensus'' without counting votes, the ability to make tough decisions, and the ability to adequately to defend oneself when making such decisions. That, I belive, should be our focus, rather than deciding what percentage of support constitutes consensus in all situations. Do keep in mind that [[m:Polling is evil]] and should be avoided where possible. Now to address Daanschr's concerns that "the ones who create the articles are not the ones who make the decisions"--I personally believe it best so; the major article writers tend to be the ones least concerned with administrivia such as blocking policies and deletion policies and the tedious boring tasks of clearing categories such as [[w:CAT:NSD]]. The job of an administrator is to be well-versed in policy matters, to have excellent common sense, and to serve as diplomats in disputes--while writing featured articles is an excellent way to gain knowledge in how to deal with disputes, it is by far not the only way, and I find that the major article writers tend to be the least capable of maintaining neutrality. Note as well that administrative permissions provide you, in theory at least, with no higher status in the community, no more influence in policy matters, and certainly not any extra tools to help you write better articles. Administrators are just that--administrators; they deal with administrative issues. Similarly, Bureaucrats deal with bureaucratic issues such as renaming users, flagging bots, and processing requests for adminship. Neither admins nor bureaucrats nor checkusers nor any other user group should have any greater influence over individual articles nor the policies governing all users and articles than any other user. Okay, ending babbling now. :D [[User:AmiDaniel|AmiDaniel]] ([[User talk:AmiDaniel|talk]]) 18:01, 10 December 2006 (UTC) :I don't like the idea of always trying to get consensus.

Sure, it takes longer, but I find the results tend to be much more beneficial.

We have to recognise that individuals bring particular viewpoints to the community, and that individuals have needs in terms of being heard, being valued etc. So we must place some value in individualism. But we are also here to create a collaborative project - which means we need to be able to listen to one another, discuss openly, and sometimes take criticism.

Anyone claiming to be able to accurately judge the "consensus" of a large group discussion without some kind of a straw poll .... Further, it is unlikely that a large fraction of participants at wikiversity will actually care enough about who operates the mops to participate repeatedly in "consensus" building. Sometimes, temporary closure can be a beautiful thing. I think initially most administrative functions, including bureaucrat status, should be fairly easily attained and moderately easily removed if people so trusted cannot learn to wield their priveleges/responsibilities effectively. This was the case when Wikipedia was a startup and helped grow the community and encyclopedia to critical mass. Of course, Wikipedia had a formal clearcut organizational structure that was fairly flat. There was the God King, the developers, everyone else. Adminship was essentially the result of having sufficient experience with the wiki and the community to be trusted to avoid really foolish blunders and trusted to be willing to help fix mistakes. At the moment Wikiversity is vertically taller than early Wikipedia was by approximately a Board of Directors, a committee, and possibly an informal subcommittee, stewards and bureaurcrats and custodians. Custodianship is not automatic after an initial introduction period. Anybody think this tall fuzzy infrastructure is helpful in retaining newcomers? How could we emulate the early structure of Wikipedia? Well perhaps once a year we could have a vote for an honorary "God King" who could occasionally decide tough issues for the community (those urgently requiring dramatic prompt action for the greater good or at least to avoid the greater bad ...) but usually keep quiet and let the community argue it out. Obviously our "God King" would not have the real authority that Jimbo started out with and has carefully preserved by stacking the Wikimedia Foundation board .... still I expect the Board (or a committee or a steward or a local bureaucrat or a local participant) might listen carefully when the honorary Wikiversity God King speaks regarding Wikiversity issues considering the position as a community spokesperson has been numerically substantiated by a majority of the votes cast determined legitimate and counted. Perhaps we should include term limits or restrict the candidates to former bureaucrats??? Notice that if you consider voting evil that can dramatically reduce the voting. One vote once a year and then the God King can help sort it all out by deciding the "consensus". No further straw polls required, unless of course the God King requests one.

But I think you're misinterpreting the gist of the maxim "voting/polls is/are evil", which should really read something like: "Votes/polls can be divisive, and they should be used sparingly, with caution, and after substantial discussion, and their results should not be taken as necessarily indicating a majority or a consensus within the community".

A wiki bureaucrat should have a good understanding of the mission of the wiki and a willingness to put the success of the project ahead of consensus. Bureaucrats are in a position to do so by '''not''' acting when they are asked to act. If a bureaucrat feels that a requested action would do more harm than good, the bureaucrat can discuss the requested action before acting. "[[w:Ochlocracy|Mob rule]]" is a potential danger in any human social system that is guided by consensus. Bureaucrats can function as a check on this danger. Bureaucrats should be experienced wiki users who are always watching for situations in which the community might be rushing into a poor decision that does not really serve the long-term interests of the project. Also, too close adherence to policy can create problems. For example, if on the last scheduled day of a community discussion some new evidence is provided, it might be wise to extend the discussion rather than close it at the scheduled time. When bureaucrats are willing to do what is best for the project '''and''' explain what they are doing it can allow the community to be thoughtful and possibly avoid rushing into a regrettable course of action. Item #4 in the list (acting without consensus, above) is a bit trickier than failure to act. When bureaucrats feel forced into taking action in the absence of community consensus there should at least be consensus among bureaucrats and a clear explanation to the community of why the action is being taken. It makes sense to me that any bureaucrat action that is not supported by prior community consensus should be open to critical evaluation by the community. There was an interesting case at the English Wikipedia in which bureaucrats "broke the rules" in deciding to grant adminship to a candidate who had an unusually low level of community support. I think the Wikiversity community needs to give some thought to the best way to deal with that kind of situation. --[[User:JWSchmidt|JWSchmidt]] 19:47, 10 December 2006 (UTC) :If precedent needs to be made, the bureaucrat better be in a position to justify this rigorously.

For example, sometimes the Wikimedia Foundation central office makes a sudden decision (such as deleting a wiki page or placing an editing ban on an individual) based on the need to protect the Foundation from legal attack or threats of legal attack. Also, there are some standing Wikimedia Foundation policies that pertain to all Wikimedia Foundation projects. I do not think we can expect a bureaucrat to simply bow to community consensus if the bureaucrat knows that there is a good reason not to initiate an action called for by a community discussion. Simply put, it is possible for community consensus to fail to identify the best course of action and it is not reasonable to tell bureaucrats that they must '''always''' do what community consensus calls for. This is similar to saying that a soldier follows orders but does have to follow an order that involves doing something illegal. However, such situations where a bureaucrat might contradict community consensus are extraordinary.

Just as the rest of the community participants can bow out at will and go do something else. We probably should define what "consensus" means locally.

More often than not it ends up consisting of an evaluation of a user's entire history of contributions rather than their fitness for adminship. This is partially due to the fact that at most other projects there's usually no concrete experience with the user exercising admin features prior to the RfA. So the community is forced to use other points of reference to evaluate the candidate. At Wikiversity, we've created a process that's different from that. Candidates for custodianship are required to be mentored for four weeks, after which they are evaluated by their mentor. The point of this process is for a candidate to have the opportunity to exercise custodian tools and demonstrate the way in which they would conduct themselves as full custodians. If the mentor provides a favorable recommendation, the candidate can apply for full custodianship, subject to community discussion. The final decision in this matter lies with the bureaucrats who are expected to evaluate the mentorship period, the recommendation and community feedback. It's not so much a question of consensus but of informed decision-making considering the interests of Wikiversity as a collaborative project as the highest priority.

It is natural for people to assume that wiki "support staff" somehow have special control over the content of Wikimedia Foundation project wikis. There is actually a more subtle and interesting relationship between the special tasks that can be performed only by "[[Wikiversity:Support staff|Support staff]]" and the "real work" that is done by all wiki participants to actually develop the project. The term "custodian" was selected as the Wikiversity term for "sysop" partly in an attempt to stress the idea that it is not a very exciting position to hold. Picture custodians who quietly sweep the floor when a school is closed at the end of the day. My hope is that if we can do a good job of engineering the Wikiversity rules for support staff then it will be possible for custodians and bureaucrats to be almost invisible to the bulk of the community. Most wikiversity participants should be able to get on with the "real work" of the wiki and all they need to know is how to do is call a custodian in case a toilet blocks up and some mopping is needed. While we can strive to make "support staff" invisible, every action taken by wiki "support staff" needs to be open to review; if there is ever a problem caused by "support staff" then the community needs to be able to correct it. At Wikipedia there are occasionally calls for some kind of formal oversight for "support staff" such as periodic performance reviews. The system that has developed to deal with "support staff" problems is more adversarial and crisis-oriented. If someone perceives a problem with Wikipedia "support staff" then in order to correct it seems like there often has to be a formal and legalistic case brought before the arbitration committee. One way that "support staff" can get in the "dog house" is by trying to use their special tools to take control of wiki content. The bottom line is, "support staff" can only indirectly influence "respect of the academic world" by keeping a clean house within Wikiversity (cleaning up vandalism, etc). It is really up to "regular" Wikiversity participants to gain the respect of the academic world.

Wikiversity is still reasonably young, and I think planning ahead with a time horizon of around 12-16 months in mind is not too unreasonable. This might help us focus on having this page meet Wikiversity's current needs, while leaving the door open to flexibility as the editing environment changes. I think it might be easier to modify this draft if we discuss each section starting from top to bottom, with less emphasis between how the sections interrelate. Once we have done this, we can look at the resulting document as a whole to see if there are any inconsistencies between what is written and what our philosophies for the bureaucrat role should be. Roughly speaking, I think the discussions we had 4-5 months ago approached this page in the other direction, so it might be fruitful to try the another way. What is written so far seems reasonable. The concerns I have at the moment are primarily "semantic" - I think we need to clarify certain things. For example, in the first section, what does "well-trusted" really mean? How about the word "consensus"? Or "civility"? Let me focus on trust in this thread. I think there are two distinct notions here we should document - the first relates to bureaucratship, say, as an "administrative role", and the second relates to bureaucrat as a "representative role". In the former, the ideal bureaucrat is probably someone who generally interprets policy in such a way that maximizes consistency and minimizes surprise. That is, they act in a way which can be reasonably anticipated by the community. In the latter, the bureaucrat is someone who the community feels is a positive influence on Wikiversity, likely someone not particularly polarizing, with a well rounded knowledge of the site. The bureaucrat is someone who would be a good ambassador for Wikiversity. However, even this brief sketch seems problematic as it seems to open the door to a policy where the bureaucrat bit can be granted relatively liberally. This in itself is not problematic - it is the fact that it seems inconsistent with what I think the bureaucrat role is intended to be (a little more selective) which makes it so. What's the best way to proceed? Perhaps this sketch is really a non-issue, but I thought it might be a good idea just to write this down. We should probably aim for policy which balances these concerns nicely, so that its consequences are manageable by the community. Enough writing for now! I will try shorter tidbits next time. --[[User:HappyCamper|HappyCamper]] 22:23, 20 April 2007 (UTC) :"planning ahead with a time horizon of around 12-16 months in mind is not too unreasonable" <-- In your thinking, is it likely that this "time horizon" will include a real Wikiversity crisis in which the project might benefit from having a good set of bcrat guidelines in place, rather than the alternative of the community struggling through a crisis without the aid of good guidelines and then getting around to making useful policy only after the crisis is over? By "good guidelines " I mean that we would be able to learn from challenges that have previously been faced by other wiki projects.--[[User:JWSchmidt|JWSchmidt]] 23:38, 20 April 2007 (UTC) ::Learning from previous challenges on other projects - this sounds like a learning project in its own right. :-) I think it would be great to pursue such a project - but there's also an inevitability about us having to learn through this process ourselves in this (local) context. We will never be able to learn everything in advance - nor prepare for every inevitability - but we should endeavour to have as much of the process as clearly defined as possible, always leaving room for fresh and critical thinking, judgement, and reflexivity. Part of this is working through what terms like [[Wikiversity:Consensus|"consensus"]] mean - and these policies should be as clear as possible while also leaving flexibility for rethinking them in new light. For example, the notion of "reasonability" is fundamental to most legal systems, but what being "reasonable" is is a very complex notion. I don't think we need to recreate an entire legal system, but rather develop a model of consensus that will work for as long as it needs to. Wikiversity's development over a timeframe of 12-16 months sounds good as a thought experiment to start off with, however. :-) [[User:Cormaggio|Cormaggio]] <sup><small>[[User talk:Cormaggio|talk]]</small></sup> 00:29, 21 April 2007 (UTC) :::Well, 12-16 months is arbitrary. Ideally, it would be nice if we could come up with something that would be workable for all time, but that does not seem achievable. So, I just picked a number that was less than infinity...something which seems manageable (at least to me). Basically, a neat concept to suggest that we should not try and solve all the possible problems that might crop up. I didn't think of the phrase "thought experiment", but actually, that's a very nice way of putting it :-) I didn't have a potential Wikiversity crisis in mind when I wrote my previous post. I'll have to think about it, but maybe I'll offer an idea that perhaps a "crisis" on a Wiki generally turns policy into a source of polarization. :::Here's another metaphor which might be useful. Originally, I thought that policies here would develop sort of like growing plants from seeds. A little water and sunlight (ie. edits to the page) here and there...and obviously, watching the plant mature. But it seems this is developing more like a piece of artwork, say, chiseling a stone sculpture. Start with a rough draft, and work away at it to get something useful. :::I feel like I am going in circles, so maybe let's sketch out a bureaucrat I think would be healthy for Wikiversity, and how they might work. Obviously, this isn't the only sort of bureaucrat that would be useful for Wikiversity, but I'll describe one which is easiest for me to do right now. So, let's see...the bureaucrat will be just a normal editor on almost all pages on Wikiversity, with the exception of those directly related to creating custodians. They will not see custodianship as a too much of a political process. Policies will tend to be seen as descriptive, not prescriptive. Possibly a wikignome by nature. They will incline on promoting liberally - particular, for those users who seem to be dedicated to generating content on Wikiversity. The custodial bit is seen as a source of convenience for users, not as a source of autonomy. Possibly see Wikiversity more in an "eventualist" light instead of "immediatist" one (or whatever the neologism is). Promotions don't need to happen on fixed schedules. Track record of dedication to the project. OK, so much for now. How does this sketch look?

For example, one of the key duties of bureaucrats is to turn wiki users into sysops (called [[Wikiversity:Custodianship|custodians]] at Wikiversity). The Wikiversity community should decide if there is some set level of community support required for custodianship or if bureaucrats can exercise some discretion at the end of a community discussion about a candidate for custodianship. --[[User:JWSchmidt|JWSchmidt]] 23:39, 7 December 2006 (UTC) == Responsibilities of bureaucrats == Well, before we can really begin drafting this policy, I think we first need to take a comprehensive look at the technical rights of bureaucrats, the "non-technical" rights of bureaucrats, and the responsibilities of bureaucrats on enwikiversity. *'''Technical rigts''': To get the obvious out of the way: bureaucrats are the only local user group capable of granting a user SysOp rights--the policy of when this permission can be used is covered (to some extent) in [[Wikiversity:Custodianship]], so I'm not sure this policy will need to elaborate much upon this. Bureaucrats are also the only local group capable of granting a user Bureaucrat status--the main purpose of this policy is to decide upon when they can and cannot do this. Among their other technical rights are the ability to rename local users and the ability to grant a user bot status. I think it very important that enwikiversity draft both a user renaming policy and a thorough [[Wikiversity:Bots|bot policy]], both of which we lack at the moment. *'''Non-technical rights''': On enwiki, we regard Bureaucrats as the ultimate judges of consensus--I believe we should maintain this idea in our Bureaucratship policy. Only bureacrats should be able to close requests for adminship and bureaucratship, approve or reject requests for name changes, and I would also like to propose that they be final authority in requests for bot status. While our focus here isn't a bot approvals process, I would suggest that we use a process similar to RfA for bot status, where users are granted bot status based upon community consensus and where the bureaucrats are the judges of this consensus. *'''What crats can't do although it's logical to think that they could''': Bureaucrats do not have the technically ability nor the authority to revoke ''any'' user status--crat, bot, or sysop. Requests for desysopping and the like must go through the [[m:Stewards]]. Note that this issue is truly not one that can be debated--'twas set in stone long ago due to a crat gone mad on enwiki. *'''Expectations of bureaucrats''': First and foremost, bureacrats must be well-trusted members of the community. They must have exceptional understanding of the way things work on Wikiversity and must be ''excellent'' judges of consensus. They must demonstrate through their extensive contributions to Wikiversity that they are not rash in decision-making nor incivil nor incompetent. Also of primary importance is a bureaucrat's ability to thoroughly explain and defend the decisions or he or she makes as well the ability to admit fault.

In theory, all custodianship "elections" should actually be ''discussions'' where the goal is attaining consensus, in which case the bureaucrat should then be required to not just look at numbers of supporters vs. opposers, but rather to thoroughly read through the discussion and determine what the true ''consensus'' of the community is. Nonetheless, that is often an idealist concept, and it may be a methodology that we will not be able to maintain for long. In any case, however, I belive that, though adminship is truly not a big deal, if ''one third'' or more of the community has good reason to oppose handing someone the mop, that person should not be made an admin--I would personally favor a much higher level of needed support (75-80%) before a Bureaucrat even considers making a user an admin. Codifying consensus clearly has its benefits--it spares crats a lot of work if they just have to look at numbers and it gives them an easy way to respond to disputes that arise about their actions, by simply citing numbers. But it is not the wiki way, nor should the task of bureaucrats simply be to count votes. I rather believe the most important quality of a prospective bureaucrat to be the ability to reasonably judge ''consensus'' without counting votes, the ability to make tough decisions, and the ability to adequately to defend oneself when making such decisions. That, I belive, should be our focus, rather than deciding what percentage of support constitutes consensus in all situations. Do keep in mind that [[m:Polling is evil]] and should be avoided where possible. Now to address Daanschr's concerns that "the ones who create the articles are not the ones who make the decisions"--I personally believe it best so; the major article writers tend to be the ones least concerned with administrivia such as blocking policies and deletion policies and the tedious boring tasks of clearing categories such as [[w:CAT:NSD]]. The job of an administrator is to be well-versed in policy matters, to have excellent common sense, and to serve as diplomats in disputes--while writing featured articles is an excellent way to gain knowledge in how to deal with disputes, it is by far not the only way, and I find that the major article writers tend to be the least capable of maintaining neutrality. Note as well that administrative permissions provide you, in theory at least, with no higher status in the community, no more influence in policy matters, and certainly not any extra tools to help you write better articles. Administrators are just that--administrators; they deal with administrative issues. Similarly, Bureaucrats deal with bureaucratic issues such as renaming users, flagging bots, and processing requests for adminship. Neither admins nor bureaucrats nor checkusers nor any other user group should have any greater influence over individual articles nor the policies governing all users and articles than any other user. Okay, ending babbling now. :D [[User:AmiDaniel|AmiDaniel]] ([[User talk:AmiDaniel|talk]]) 18:01, 10 December 2006 (UTC) :I don't like the idea of always trying to get consensus. The result of this is unending discussions on policy and a conservative, defensive community. I would prefer to have a system which can be able to changed things. Such a system could be top-down with a clear leader, who can make tough decisions, a kind of democratic system where majorities can overrule minorities, or a corporate system where institutes within Wikiversity can have a say on policy. It depends on what Wikiversity will try to become. At the moment it is not clear at all what it will be.--[[User:Daanschr|Daanschr]] 18:18, 10 December 2006 (UTC) ::And contrarily, the concept of a top-down hierarchial power structure sends shivers up my spine, as no individual, or even group of individuals, can possibly have the best know-how in all situations. I find that, in a wiki structure, discussion seems to be the best way at attaining results, as it allows for people's opinions to be influenced, allows for more equality among membrs of the community, and helps to prevent narrow, dogmatic views on issues. Sure, it takes longer, but I find the results tend to be much more beneficial. Note as well that by consensus I don't mean that everyone has to agree upon something for it to be done, but rather that decisions should be made by the community as a whole rather than just a handful of individuals, or even a narrow majority of the community.

The best means to maintaining the motivation and participation of all involved in a wiki is to recognise that there is often a diversity of points of view, and that this diversity needs to be reflected in the consensus-of-the-time (which can itself be discussed and changed). We have to recognise that individuals bring particular viewpoints to the community, and that individuals have needs in terms of being heard, being valued etc. So we must place some value in individualism. But we are also here to create a collaborative project - which means we need to be able to listen to one another, discuss openly, and sometimes take criticism.

Anyone claiming to be able to accurately judge the "consensus" of a large group discussion without some kind of a straw poll .... Further, it is unlikely that a large fraction of participants at wikiversity will actually care enough about who operates the mops to participate repeatedly in "consensus" building. Sometimes, temporary closure can be a beautiful thing. I think initially most administrative functions, including bureaucrat status, should be fairly easily attained and moderately easily removed if people so trusted cannot learn to wield their priveleges/responsibilities effectively. This was the case when Wikipedia was a startup and helped grow the community and encyclopedia to critical mass. Of course, Wikipedia had a formal clearcut organizational structure that was fairly flat. There was the God King, the developers, everyone else. Adminship was essentially the result of having sufficient experience with the wiki and the community to be trusted to avoid really foolish blunders and trusted to be willing to help fix mistakes. At the moment Wikiversity is vertically taller than early Wikipedia was by approximately a Board of Directors, a committee, and possibly an informal subcommittee, stewards and bureaurcrats and custodians. Custodianship is not automatic after an initial introduction period. Anybody think this tall fuzzy infrastructure is helpful in retaining newcomers? How could we emulate the early structure of Wikipedia? Well perhaps once a year we could have a vote for an honorary "God King" who could occasionally decide tough issues for the community (those urgently requiring dramatic prompt action for the greater good or at least to avoid the greater bad ...) but usually keep quiet and let the community argue it out. Obviously our "God King" would not have the real authority that Jimbo started out with and has carefully preserved by stacking the Wikimedia Foundation board .... still I expect the Board (or a committee or a steward or a local bureaucrat or a local participant) might listen carefully when the honorary Wikiversity God King speaks regarding Wikiversity issues considering the position as a community spokesperson has been numerically substantiated by a majority of the votes cast determined legitimate and counted. Perhaps we should include term limits or restrict the candidates to former bureaucrats??? Notice that if you consider voting evil that can dramatically reduce the voting. One vote once a year and then the God King can help sort it all out by deciding the "consensus". No further straw polls required, unless of course the God King requests one.

A wiki bureaucrat should have a good understanding of the mission of the wiki and a willingness to put the success of the project ahead of consensus. Bureaucrats are in a position to do so by '''not''' acting when they are asked to act. If a bureaucrat feels that a requested action would do more harm than good, the bureaucrat can discuss the requested action before acting. "[[w:Ochlocracy|Mob rule]]" is a potential danger in any human social system that is guided by consensus. Bureaucrats can function as a check on this danger. Bureaucrats should be experienced wiki users who are always watching for situations in which the community might be rushing into a poor decision that does not really serve the long-term interests of the project. Also, too close adherence to policy can create problems. For example, if on the last scheduled day of a community discussion some new evidence is provided, it might be wise to extend the discussion rather than close it at the scheduled time. When bureaucrats are willing to do what is best for the project '''and''' explain what they are doing it can allow the community to be thoughtful and possibly avoid rushing into a regrettable course of action. Item #4 in the list (acting without consensus, above) is a bit trickier than failure to act. When bureaucrats feel forced into taking action in the absence of community consensus there should at least be consensus among bureaucrats and a clear explanation to the community of why the action is being taken. It makes sense to me that any bureaucrat action that is not supported by prior community consensus should be open to critical evaluation by the community. There was an interesting case at the English Wikipedia in which bureaucrats "broke the rules" in deciding to grant adminship to a candidate who had an unusually low level of community support. I think the Wikiversity community needs to give some thought to the best way to deal with that kind of situation. --[[User:JWSchmidt|JWSchmidt]] 19:47, 10 December 2006 (UTC) :If precedent needs to be made, the bureaucrat better be in a position to justify this rigorously.

For example, sometimes the Wikimedia Foundation central office makes a sudden decision (such as deleting a wiki page or placing an editing ban on an individual) based on the need to protect the Foundation from legal attack or threats of legal attack. Also, there are some standing Wikimedia Foundation policies that pertain to all Wikimedia Foundation projects. I do not think we can expect a bureaucrat to simply bow to community consensus if the bureaucrat knows that there is a good reason not to initiate an action called for by a community discussion. Simply put, it is possible for community consensus to fail to identify the best course of action and it is not reasonable to tell bureaucrats that they must '''always''' do what community consensus calls for. This is similar to saying that a soldier follows orders but does have to follow an order that involves doing something illegal.

The community can always appeal the the higher hiearchy to activate some additional bureaucrats with diverse views if a cabal of consistently agreeing bureaucrats seem to consistently take action opposing the "consensus" of the rest of the Wikiversity community within the scope of discussion. (I assume literature students will not be interested in dictating how engineering sections implement local java labs for finite element analysis ... unless it effects their online response from Wikimedia servers.) Just as the rest of the community participants can bow out at will and go do something else. We probably should define what "consensus" means locally. Some people seem to mean a simple majority while others seem to hold out for unanimous and yet others prefer a fuzzy definition preserving the bureaucrats independence and ability to summarize and act as they see fit. Meanwhile, the "voting is evil" faction seems to prefer guessing while my own "voting is ok" faction prefers concise quantitative data summarizing the final instantaneous result of the discussions.

A custodian who does not participate in content creation might be more likely to just roll back a strange edit or delete an unusual page without taking the time to find out what the original contributor of that content was trying to accomplish. Sometimes new editors are trying to contribute and they need help to learn how, not a swift kick from a custodian.

More often than not it ends up consisting of an evaluation of a user's entire history of contributions rather than their fitness for adminship. This is partially due to the fact that at most other projects there's usually no concrete experience with the user exercising admin features prior to the RfA. So the community is forced to use other points of reference to evaluate the candidate. At Wikiversity, we've created a process that's different from that. Candidates for custodianship are required to be mentored for four weeks, after which they are evaluated by their mentor. The point of this process is for a candidate to have the opportunity to exercise custodian tools and demonstrate the way in which they would conduct themselves as full custodians. If the mentor provides a favorable recommendation, the candidate can apply for full custodianship, subject to community discussion. The final decision in this matter lies with the bureaucrats who are expected to evaluate the mentorship period, the recommendation and community feedback. It's not so much a question of consensus but of informed decision-making considering the interests of Wikiversity as a collaborative project as the highest priority. For other issues, I would expect for bureaucrats to act in the same thoughtful and constructive manner. [[User:sebmol|sebmol]] [[User talk:sebmol|<sup>?</sup>]] 16:49, 11 December 2006 (UTC) :"trying to gain the respect of the academic world" <-- I think many people outside of the wiki world are baffled by how wikis function. It is natural for people to assume that wiki "support staff" somehow have special control over the content of Wikimedia Foundation project wikis. There is actually a more subtle and interesting relationship between the special tasks that can be performed only by "[[Wikiversity:Support staff|Support staff]]" and the "real work" that is done by all wiki participants to actually develop the project. The term "custodian" was selected as the Wikiversity term for "sysop" partly in an attempt to stress the idea that it is not a very exciting position to hold. Picture custodians who quietly sweep the floor when a school is closed at the end of the day. My hope is that if we can do a good job of engineering the Wikiversity rules for support staff then it will be possible for custodians and bureaucrats to be almost invisible to the bulk of the community. Most wikiversity participants should be able to get on with the "real work" of the wiki and all they need to know is how to do is call a custodian in case a toilet blocks up and some mopping is needed. While we can strive to make "support staff" invisible, every action taken by wiki "support staff" needs to be open to review; if there is ever a problem caused by "support staff" then the community needs to be able to correct it. At Wikipedia there are occasionally calls for some kind of formal oversight for "support staff" such as periodic performance reviews. The system that has developed to deal with "support staff" problems is more adversarial and crisis-oriented. If someone perceives a problem with Wikipedia "support staff" then in order to correct it seems like there often has to be a formal and legalistic case brought before the arbitration committee. One way that "support staff" can get in the "dog house" is by trying to use their special tools to take control of wiki content. The bottom line is, "support staff" can only indirectly influence "respect of the academic world" by keeping a clean house within Wikiversity (cleaning up vandalism, etc). It is really up to "regular" Wikiversity participants to gain the respect of the academic world. However, it may be useful for Wikiversity to create a new type of "functionary" that can specialize for "professional" contacts with the academic world.

I have a few ideas which might be handy. I think it would be a good idea to aim for a document which we can expect to remain stable for say, a year or so. Wikiversity is still reasonably young, and I think planning ahead with a time horizon of around 12-16 months in mind is not too unreasonable. This might help us focus on having this page meet Wikiversity's current needs, while leaving the door open to flexibility as the editing environment changes. I think it might be easier to modify this draft if we discuss each section starting from top to bottom, with less emphasis between how the sections interrelate. Once we have done this, we can look at the resulting document as a whole to see if there are any inconsistencies between what is written and what our philosophies for the bureaucrat role should be. Roughly speaking, I think the discussions we had 4-5 months ago approached this page in the other direction, so it might be fruitful to try the another way. What is written so far seems reasonable. The concerns I have at the moment are primarily "semantic" - I think we need to clarify certain things. For example, in the first section, what does "well-trusted" really mean? How about the word "consensus"? Or "civility"? Let me focus on trust in this thread. I think there are two distinct notions here we should document - the first relates to bureaucratship, say, as an "administrative role", and the second relates to bureaucrat as a "representative role". In the former, the ideal bureaucrat is probably someone who generally interprets policy in such a way that maximizes consistency and minimizes surprise. That is, they act in a way which can be reasonably anticipated by the community. In the latter, the bureaucrat is someone who the community feels is a positive influence on Wikiversity, likely someone not particularly polarizing, with a well rounded knowledge of the site. The bureaucrat is someone who would be a good ambassador for Wikiversity. However, even this brief sketch seems problematic as it seems to open the door to a policy where the bureaucrat bit can be granted relatively liberally. This in itself is not problematic - it is the fact that it seems inconsistent with what I think the bureaucrat role is intended to be (a little more selective) which makes it so. What's the best way to proceed? Perhaps this sketch is really a non-issue, but I thought it might be a good idea just to write this down. We should probably aim for policy which balances these concerns nicely, so that its consequences are manageable by the community. Enough writing for now! I will try shorter tidbits next time. --[[User:HappyCamper|HappyCamper]] 22:23, 20 April 2007 (UTC) :"planning ahead with a time horizon of around 12-16 months in mind is not too unreasonable" <-- In your thinking, is it likely that this "time horizon" will include a real Wikiversity crisis in which the project might benefit from having a good set of bcrat guidelines in place, rather than the alternative of the community struggling through a crisis without the aid of good guidelines and then getting around to making useful policy only after the crisis is over?

We will never be able to learn everything in advance - nor prepare for every inevitability - but we should endeavour to have as much of the process as clearly defined as possible, always leaving room for fresh and critical thinking, judgement, and reflexivity. Part of this is working through what terms like [[Wikiversity:Consensus|"consensus"]] mean - and these policies should be as clear as possible while also leaving flexibility for rethinking them in new light. For example, the notion of "reasonability" is fundamental to most legal systems, but what being "reasonable" is is a very complex notion. I don't think we need to recreate an entire legal system, but rather develop a model of consensus that will work for as long as it needs to.

So, let's see...the bureaucrat will be just a normal editor on almost all pages on Wikiversity, with the exception of those directly related to creating custodians. They will not see custodianship as a too much of a political process. Policies will tend to be seen as descriptive, not prescriptive. Possibly a wikignome by nature. They will incline on promoting liberally - particular, for those users who seem to be dedicated to generating content on Wikiversity. The custodial bit is seen as a source of convenience for users, not as a source of autonomy.

For example, one of the key duties of bureaucrats is to turn wiki users into sysops (called [[Wikiversity:Custodianship|custodians]] at Wikiversity). The Wikiversity community should decide if there is some set level of community support required for custodianship or if bureaucrats can exercise some discretion at the end of a community discussion about a candidate for custodianship. --[[User:JWSchmidt|JWSchmidt]] 23:39, 7 December 2006 (UTC) == Responsibilities of bureaucrats == Well, before we can really begin drafting this policy, I think we first need to take a comprehensive look at the technical rights of bureaucrats, the "non-technical" rights of bureaucrats, and the responsibilities of bureaucrats on enwikiversity. *'''Technical rigts''': To get the obvious out of the way: bureaucrats are the only local user group capable of granting a user SysOp rights--the policy of when this permission can be used is covered (to some extent) in [[Wikiversity:Custodianship]], so I'm not sure this policy will need to elaborate much upon this. Bureaucrats are also the only local group capable of granting a user Bureaucrat status--the main purpose of this policy is to decide upon when they can and cannot do this. Among their other technical rights are the ability to rename local users and the ability to grant a user bot status. I think it very important that enwikiversity draft both a user renaming policy and a thorough [[Wikiversity:Bots|bot policy]], both of which we lack at the moment. *'''Non-technical rights''': On enwiki, we regard Bureaucrats as the ultimate judges of consensus--I believe we should maintain this idea in our Bureaucratship policy. Only bureacrats should be able to close requests for adminship and bureaucratship, approve or reject requests for name changes, and I would also like to propose that they be final authority in requests for bot status. While our focus here isn't a bot approvals process, I would suggest that we use a process similar to RfA for bot status, where users are granted bot status based upon community consensus and where the bureaucrats are the judges of this consensus. *'''What crats can't do although it's logical to think that they could''': Bureaucrats do not have the technically ability nor the authority to revoke ''any'' user status--crat, bot, or sysop. Requests for desysopping and the like must go through the [[m:Stewards]]. Note that this issue is truly not one that can be debated--'twas set in stone long ago due to a crat gone mad on enwiki. *'''Expectations of bureaucrats''': First and foremost, bureacrats must be well-trusted members of the community. They must have exceptional understanding of the way things work on Wikiversity and must be ''excellent'' judges of consensus. They must demonstrate through their extensive contributions to Wikiversity that they are not rash in decision-making nor incivil nor incompetent. Also of primary importance is a bureaucrat's ability to thoroughly explain and defend the decisions or he or she makes as well the ability to admit fault. Anyway this is just some random babbling/brainstorming. Please discuss :).

In theory, all custodianship "elections" should actually be ''discussions'' where the goal is attaining consensus, in which case the bureaucrat should then be required to not just look at numbers of supporters vs. opposers, but rather to thoroughly read through the discussion and determine what the true ''consensus'' of the community is. Nonetheless, that is often an idealist concept, and it may be a methodology that we will not be able to maintain for long. In any case, however, I belive that, though adminship is truly not a big deal, if ''one third'' or more of the community has good reason to oppose handing someone the mop, that person should not be made an admin--I would personally favor a much higher level of needed support (75-80%) before a Bureaucrat even considers making a user an admin. Codifying consensus clearly has its benefits--it spares crats a lot of work if they just have to look at numbers and it gives them an easy way to respond to disputes that arise about their actions, by simply citing numbers. But it is not the wiki way, nor should the task of bureaucrats simply be to count votes. I rather believe the most important quality of a prospective bureaucrat to be the ability to reasonably judge ''consensus'' without counting votes, the ability to make tough decisions, and the ability to adequately to defend oneself when making such decisions. That, I belive, should be our focus, rather than deciding what percentage of support constitutes consensus in all situations. Do keep in mind that [[m:Polling is evil]] and should be avoided where possible. Now to address Daanschr's concerns that "the ones who create the articles are not the ones who make the decisions"--I personally believe it best so; the major article writers tend to be the ones least concerned with administrivia such as blocking policies and deletion policies and the tedious boring tasks of clearing categories such as [[w:CAT:NSD]]. The job of an administrator is to be well-versed in policy matters, to have excellent common sense, and to serve as diplomats in disputes--while writing featured articles is an excellent way to gain knowledge in how to deal with disputes, it is by far not the only way, and I find that the major article writers tend to be the least capable of maintaining neutrality. Note as well that administrative permissions provide you, in theory at least, with no higher status in the community, no more influence in policy matters, and certainly not any extra tools to help you write better articles. Administrators are just that--administrators; they deal with administrative issues. Similarly, Bureaucrats deal with bureaucratic issues such as renaming users, flagging bots, and processing requests for adminship. Neither admins nor bureaucrats nor checkusers nor any other user group should have any greater influence over individual articles nor the policies governing all users and articles than any other user. Okay, ending babbling now. :D [[User:AmiDaniel|AmiDaniel]] ([[User talk:AmiDaniel|talk]]) 18:01, 10 December 2006 (UTC) :I don't like the idea of always trying to get consensus. The result of this is unending discussions on policy and a conservative, defensive community. I would prefer to have a system which can be able to changed things. Such a system could be top-down with a clear leader, who can make tough decisions, a kind of democratic system where majorities can overrule minorities, or a corporate system where institutes within Wikiversity can have a say on policy. It depends on what Wikiversity will try to become. At the moment it is not clear at all what it will be.--[[User:Daanschr|Daanschr]] 18:18, 10 December 2006 (UTC) ::And contrarily, the concept of a top-down hierarchial power structure sends shivers up my spine, as no individual, or even group of individuals, can possibly have the best know-how in all situations. I find that, in a wiki structure, discussion seems to be the best way at attaining results, as it allows for people's opinions to be influenced, allows for more equality among membrs of the community, and helps to prevent narrow, dogmatic views on issues. Sure, it takes longer, but I find the results tend to be much more beneficial. Note as well that by consensus I don't mean that everyone has to agree upon something for it to be done, but rather that decisions should be made by the community as a whole rather than just a handful of individuals, or even a narrow majority of the community.

The best means to maintaining the motivation and participation of all involved in a wiki is to recognise that there is often a diversity of points of view, and that this diversity needs to be reflected in the consensus-of-the-time (which can itself be discussed and changed). We have to recognise that individuals bring particular viewpoints to the community, and that individuals have needs in terms of being heard, being valued etc. So we must place some value in individualism. But we are also here to create a collaborative project - which means we need to be able to listen to one another, discuss openly, and sometimes take criticism. All of this applies to anyone - including custodians and bureaucrats. But we can't give up our base of consensus - otherwise it would not be a truly collaborative project.

Anyone claiming to be able to accurately judge the "consensus" of a large group discussion without some kind of a straw poll .... Further, it is unlikely that a large fraction of participants at wikiversity will actually care enough about who operates the mops to participate repeatedly in "consensus" building. Sometimes, temporary closure can be a beautiful thing. I think initially most administrative functions, including bureaucrat status, should be fairly easily attained and moderately easily removed if people so trusted cannot learn to wield their priveleges/responsibilities effectively. This was the case when Wikipedia was a startup and helped grow the community and encyclopedia to critical mass. Of course, Wikipedia had a formal clearcut organizational structure that was fairly flat. There was the God King, the developers, everyone else. Adminship was essentially the result of having sufficient experience with the wiki and the community to be trusted to avoid really foolish blunders and trusted to be willing to help fix mistakes. At the moment Wikiversity is vertically taller than early Wikipedia was by approximately a Board of Directors, a committee, and possibly an informal subcommittee, stewards and bureaurcrats and custodians. Custodianship is not automatic after an initial introduction period. Anybody think this tall fuzzy infrastructure is helpful in retaining newcomers? How could we emulate the early structure of Wikipedia? Well perhaps once a year we could have a vote for an honorary "God King" who could occasionally decide tough issues for the community (those urgently requiring dramatic prompt action for the greater good or at least to avoid the greater bad ...) but usually keep quiet and let the community argue it out. Obviously our "God King" would not have the real authority that Jimbo started out with and has carefully preserved by stacking the Wikimedia Foundation board .... still I expect the Board (or a committee or a steward or a local bureaucrat or a local participant) might listen carefully when the honorary Wikiversity God King speaks regarding Wikiversity issues considering the position as a community spokesperson has been numerically substantiated by a majority of the votes cast determined legitimate and counted. Perhaps we should include term limits or restrict the candidates to former bureaucrats??? Notice that if you consider voting evil that can dramatically reduce the voting. One vote once a year and then the God King can help sort it all out by deciding the "consensus". No further straw polls required, unless of course the God King requests one.

No project has created their own GodKing, and I believe it would be entirely inappropriate to create such a thing. Consensus isn't that hard to ascertain - if there is opposition, it will be clear on the relevant pages. If needs be, polls can certainly be used to gauge opinion. But I think you're misinterpreting the gist of the maxim "voting/polls is/are evil", which should really read something like: "Votes/polls can be divisive, and they should be used sparingly, with caution, and after substantial discussion, and their results should not be taken as necessarily indicating a majority or a consensus within the community".

A wiki bureaucrat should have a good understanding of the mission of the wiki and a willingness to put the success of the project ahead of consensus. Bureaucrats are in a position to do so by '''not''' acting when they are asked to act. If a bureaucrat feels that a requested action would do more harm than good, the bureaucrat can discuss the requested action before acting. "[[w:Ochlocracy|Mob rule]]" is a potential danger in any human social system that is guided by consensus. Bureaucrats can function as a check on this danger. Bureaucrats should be experienced wiki users who are always watching for situations in which the community might be rushing into a poor decision that does not really serve the long-term interests of the project. Also, too close adherence to policy can create problems. For example, if on the last scheduled day of a community discussion some new evidence is provided, it might be wise to extend the discussion rather than close it at the scheduled time. When bureaucrats are willing to do what is best for the project '''and''' explain what they are doing it can allow the community to be thoughtful and possibly avoid rushing into a regrettable course of action. Item #4 in the list (acting without consensus, above) is a bit trickier than failure to act. When bureaucrats feel forced into taking action in the absence of community consensus there should at least be consensus among bureaucrats and a clear explanation to the community of why the action is being taken. It makes sense to me that any bureaucrat action that is not supported by prior community consensus should be open to critical evaluation by the community. There was an interesting case at the English Wikipedia in which bureaucrats "broke the rules" in deciding to grant adminship to a candidate who had an unusually low level of community support. I think the Wikiversity community needs to give some thought to the best way to deal with that kind of situation. --[[User:JWSchmidt|JWSchmidt]] 19:47, 10 December 2006 (UTC) :If precedent needs to be made, the bureaucrat better be in a position to justify this rigorously.

Even consensus amongst bureaucrats is not enough excuse.----[[User:Hillgentleman|Hillgentleman]]|[[User talk:hillgentleman|Talk]] 23:23, 10 December 2006 (UTC) ::I suppose we could make a list of everything that can "trump" community consensus. For example, sometimes the Wikimedia Foundation central office makes a sudden decision (such as deleting a wiki page or placing an editing ban on an individual) based on the need to protect the Foundation from legal attack or threats of legal attack. Also, there are some standing Wikimedia Foundation policies that pertain to all Wikimedia Foundation projects. I do not think we can expect a bureaucrat to simply bow to community consensus if the bureaucrat knows that there is a good reason not to initiate an action called for by a community discussion. Simply put, it is possible for community consensus to fail to identify the best course of action and it is not reasonable to tell bureaucrats that they must '''always''' do what community consensus calls for. This is similar to saying that a soldier follows orders but does have to follow an order that involves doing something illegal. However, such situations where a bureaucrat might contradict community consensus are extraordinary. For the vast majority of bureaucrat actions there is no conflict with community consensus or likelihood that anyone would ever question the action. --[[User:JWSchmidt|JWSchmidt]] 02:44, 11 December 2006 (UTC) :::I agree with JWSchmidt that the interest of Wikiversity should be above the interest of single individuals who damage the whole project.

(I assume literature students will not be interested in dictating how engineering sections implement local java labs for finite element analysis ... unless it effects their online response from Wikimedia servers.) Just as the rest of the community participants can bow out at will and go do something else. We probably should define what "consensus" means locally. Some people seem to mean a simple majority while others seem to hold out for unanimous and yet others prefer a fuzzy definition preserving the bureaucrats independence and ability to summarize and act as they see fit.

[[User:Cormaggio|Cormaggio]] <sup><small>[[User talk:Cormaggio|talk]]</small></sup> 16:26, 12 December 2006 (UTC) ::::Academic standards sounds good, or what about 'academic expertise'?--[[User:Daanschr|Daanschr]] 18:27, 12 December 2006 (UTC) To give a little insight into why the model for RfA we have here was chosen: an experience I and others have made in other projects is that the process for attaining adminship can become exceedingly arduous and personal. More often than not it ends up consisting of an evaluation of a user's entire history of contributions rather than their fitness for adminship. This is partially due to the fact that at most other projects there's usually no concrete experience with the user exercising admin features prior to the RfA. So the community is forced to use other points of reference to evaluate the candidate. At Wikiversity, we've created a process that's different from that. Candidates for custodianship are required to be mentored for four weeks, after which they are evaluated by their mentor. The point of this process is for a candidate to have the opportunity to exercise custodian tools and demonstrate the way in which they would conduct themselves as full custodians. If the mentor provides a favorable recommendation, the candidate can apply for full custodianship, subject to community discussion. The final decision in this matter lies with the bureaucrats who are expected to evaluate the mentorship period, the recommendation and community feedback. It's not so much a question of consensus but of informed decision-making considering the interests of Wikiversity as a collaborative project as the highest priority. For other issues, I would expect for bureaucrats to act in the same thoughtful and constructive manner. [[User:sebmol|sebmol]] [[User talk:sebmol|<sup>?</sup>]] 16:49, 11 December 2006 (UTC) :"trying to gain the respect of the academic world" <-- I think many people outside of the wiki world are baffled by how wikis function. It is natural for people to assume that wiki "support staff" somehow have special control over the content of Wikimedia Foundation project wikis. There is actually a more subtle and interesting relationship between the special tasks that can be performed only by "[[Wikiversity:Support staff|Support staff]]" and the "real work" that is done by all wiki participants to actually develop the project. The term "custodian" was selected as the Wikiversity term for "sysop" partly in an attempt to stress the idea that it is not a very exciting position to hold. Picture custodians who quietly sweep the floor when a school is closed at the end of the day. My hope is that if we can do a good job of engineering the Wikiversity rules for support staff then it will be possible for custodians and bureaucrats to be almost invisible to the bulk of the community. Most wikiversity participants should be able to get on with the "real work" of the wiki and all they need to know is how to do is call a custodian in case a toilet blocks up and some mopping is needed. While we can strive to make "support staff" invisible, every action taken by wiki "support staff" needs to be open to review; if there is ever a problem caused by "support staff" then the community needs to be able to correct it. At Wikipedia there are occasionally calls for some kind of formal oversight for "support staff" such as periodic performance reviews. The system that has developed to deal with "support staff" problems is more adversarial and crisis-oriented. If someone perceives a problem with Wikipedia "support staff" then in order to correct it seems like there often has to be a formal and legalistic case brought before the arbitration committee. One way that "support staff" can get in the "dog house" is by trying to use their special tools to take control of wiki content. The bottom line is, "support staff" can only indirectly influence "respect of the academic world" by keeping a clean house within Wikiversity (cleaning up vandalism, etc). It is really up to "regular" Wikiversity participants to gain the respect of the academic world. However, it may be useful for Wikiversity to create a new type of "functionary" that can specialize for "professional" contacts with the academic world. There are some ideas along this line [[Wikiversity:Review board#Ambassadorial function|here]]. --[[User:JWSchmidt|JWSchmidt]] 17:37, 11 December 2006 (UTC) ::If the scholarly ethics will be enforced by the support staff, then their roll will not be invisible. Do you mean with invisible that the support staff will only be concerned with fighting vandalism? The arbitration comittee has made decisions which are questionable. I wouldn't like to have such an institution on Wikiversity.--[[User:Daanschr|Daanschr]] 10:14, 12 December 2006 (UTC) :::I think that, on scholarly ethics and all other principles of good practice here, while they are vital to developing a high quality resource, I don't think they are of immediate relevance to this discussion on what bureaucrats/support staff should do. Bureaucrats and custodians should not get involved ''in their capacities as support staff'' in the implementation of such policies - they should get involved in discussing such policies and applying them as completely equal community members. As far as I can see it, the only policies that would be of direct relevance to a bureaucrat's or custodian's position would be those around civility - and even then, it is still a ''community'' issue, to perhaps be implemented by a member of the "support staff". What other types of policies could be enforceable by support staff?

It makes sense to me that any bureaucrat action that is not supported by prior community consensus should be open to critical evaluation by the community.'' Here the definition of community puzzles me. How is it possible that if a community can't reach consensus, and the bureacrats make the decision, that the same community is able to revert the decision, which will be hard if there is no consensus. In essence it means that the bureaucrats decide.--[[User:Daanschr|Daanschr]] 20:52, 12 December 2006 (UTC) ::::::I misread the line on the Germans.

Just counting votes without determining that the votes are reasonable and fair is "mindless"; you could have a bot do it.

(I have read that book: very impressive)--[[User:Daanschr|Daanschr]] 08:21, 15 December 2006 (UTC) == New draft - ideas and such == Great to see things moving along! I have a few ideas which might be handy. I think it would be a good idea to aim for a document which we can expect to remain stable for say, a year or so. Wikiversity is still reasonably young, and I think planning ahead with a time horizon of around 12-16 months in mind is not too unreasonable. This might help us focus on having this page meet Wikiversity's current needs, while leaving the door open to flexibility as the editing environment changes. I think it might be easier to modify this draft if we discuss each section starting from top to bottom, with less emphasis between how the sections interrelate. Once we have done this, we can look at the resulting document as a whole to see if there are any inconsistencies between what is written and what our philosophies for the bureaucrat role should be. Roughly speaking, I think the discussions we had 4-5 months ago approached this page in the other direction, so it might be fruitful to try the another way. What is written so far seems reasonable. The concerns I have at the moment are primarily "semantic" - I think we need to clarify certain things. For example, in the first section, what does "well-trusted" really mean? How about the word "consensus"? Or "civility"? Let me focus on trust in this thread. I think there are two distinct notions here we should document - the first relates to bureaucratship, say, as an "administrative role", and the second relates to bureaucrat as a "representative role". In the former, the ideal bureaucrat is probably someone who generally interprets policy in such a way that maximizes consistency and minimizes surprise. That is, they act in a way which can be reasonably anticipated by the community. In the latter, the bureaucrat is someone who the community feels is a positive influence on Wikiversity, likely someone not particularly polarizing, with a well rounded knowledge of the site. The bureaucrat is someone who would be a good ambassador for Wikiversity. However, even this brief sketch seems problematic as it seems to open the door to a policy where the bureaucrat bit can be granted relatively liberally. This in itself is not problematic - it is the fact that it seems inconsistent with what I think the bureaucrat role is intended to be (a little more selective) which makes it so. What's the best way to proceed? Perhaps this sketch is really a non-issue, but I thought it might be a good idea just to write this down. We should probably aim for policy which balances these concerns nicely, so that its consequences are manageable by the community. Enough writing for now! I will try shorter tidbits next time. --[[User:HappyCamper|HappyCamper]] 22:23, 20 April 2007 (UTC) :"planning ahead with a time horizon of around 12-16 months in mind is not too unreasonable" <-- In your thinking, is it likely that this "time horizon" will include a real Wikiversity crisis in which the project might benefit from having a good set of bcrat guidelines in place, rather than the alternative of the community struggling through a crisis without the aid of good guidelines and then getting around to making useful policy only after the crisis is over? By "good guidelines " I mean that we would be able to learn from challenges that have previously been faced by other wiki projects.--[[User:JWSchmidt|JWSchmidt]] 23:38, 20 April 2007 (UTC) ::Learning from previous challenges on other projects - this sounds like a learning project in its own right. :-) I think it would be great to pursue such a project - but there's also an inevitability about us having to learn through this process ourselves in this (local) context. We will never be able to learn everything in advance - nor prepare for every inevitability - but we should endeavour to have as much of the process as clearly defined as possible, always leaving room for fresh and critical thinking, judgement, and reflexivity. Part of this is working through what terms like [[Wikiversity:Consensus|"consensus"]] mean - and these policies should be as clear as possible while also leaving flexibility for rethinking them in new light. For example, the notion of "reasonability" is fundamental to most legal systems, but what being "reasonable" is is a very complex notion. I don't think we need to recreate an entire legal system, but rather develop a model of consensus that will work for as long as it needs to. Wikiversity's development over a timeframe of 12-16 months sounds good as a thought experiment to start off with, however. :-) [[User:Cormaggio|Cormaggio]] <sup><small>[[User talk:Cormaggio|talk]]</small></sup> 00:29, 21 April 2007 (UTC) :::Well, 12-16 months is arbitrary. Ideally, it would be nice if we could come up with something that would be workable for all time, but that does not seem achievable. So, I just picked a number that was less than infinity...something which seems manageable (at least to me). Basically, a neat concept to suggest that we should not try and solve all the possible problems that might crop up. I didn't think of the phrase "thought experiment", but actually, that's a very nice way of putting it :-) I didn't have a potential Wikiversity crisis in mind when I wrote my previous post. I'll have to think about it, but maybe I'll offer an idea that perhaps a "crisis" on a Wiki generally turns policy into a source of polarization. :::Here's another metaphor which might be useful. Originally, I thought that policies here would develop sort of like growing plants from seeds. A little water and sunlight (ie. edits to the page) here and there...and obviously, watching the plant mature. But it seems this is developing more like a piece of artwork, say, chiseling a stone sculpture. Start with a rough draft, and work away at it to get something useful. :::I feel like I am going in circles, so maybe let's sketch out a bureaucrat I think would be healthy for Wikiversity, and how they might work. Obviously, this isn't the only sort of bureaucrat that would be useful for Wikiversity, but I'll describe one which is easiest for me to do right now. So, let's see...the bureaucrat will be just a normal editor on almost all pages on Wikiversity, with the exception of those directly related to creating custodians. They will not see custodianship as a too much of a political process. Policies will tend to be seen as descriptive, not prescriptive. Possibly a wikignome by nature. They will incline on promoting liberally - particular, for those users who seem to be dedicated to generating content on Wikiversity. The custodial bit is seen as a source of convenience for users, not as a source of autonomy. Possibly see Wikiversity more in an "eventualist" light instead of "immediatist" one (or whatever the neologism is). Promotions don't need to happen on fixed schedules.

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. This calls into question the reliability of the essay. </blockquote> Could an administrator make this addition for me?

This includes: *[[Quantum Ultra fast lasers#Future thought experiment|Personal speculative fiction]] in an otherwise "nonfiction" article *Uploading nonsense LLM-created [[:File:Rontosecond pulse laser (Schematic).jpg|diagrams]] and [[:File:Rontosecond pulse laser (Futuristic).jpg|renders]] for nonexistent lab equipment, with fake source (on Commons, he indicated these files as having been created by him using an LLM) *Uploading nonsense LLM-created images of equations with obvious artifacts. 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. Much of his writing is also of extremely poor quality, to the point where it's not clear whether it's written by him or an LLM.

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.

Please leave feedback in the discussion section above. '''Introduction''' How would you break a metal rod if you could only use your hands? '''1.''' Pull it apart or compress it (not usually the easiest way) '''2.''' Twist it '''3.''' Bend it Each of these methods induce stress into the rod in a different way. Mohr's circle helps analyse this. For now, only the first two ways will be analysed. '''1.Tension/compression: ''' Below is a diagram of a rod with a circular cross-section that is subjected to a tensile force at either end.(When you pull the rod apart you are exerting a tensile force). Let us look at a square element at the surface of the rod: [[File:Diag1.JPG]] How do you imagine the square element would react to the tensile force? The force will 'stretch' the rod and the square element, as shown below: [[File:Mohr diag2.JPG]] Therefore the force applied at either end has produced a tensile stress, <big>'''<math>\sigma_x</math>'''</big>, on the element, as shown below: [[File:Mohr_diag3.JPG‎ ]] where: <math>\sigma_x = \frac{F}{A} </math> Similarly, a Compressive force on the rod would induce a compressive stress on the square element, as shown below: [[File:Mohr30.PNG]] '''2. Torsion ''' In this case, the rod is subjected to a torque (twisting force) at either end: [[File:Mohr diag5.JPG]] How do you imagine the element would stretch this time? Answer: The left side of the square element would stretch upwards, the right side would stretch downwards, as shown below. The stress induced by this shearing motion is called shear stress. It's symbol is, <big>'''<math>\tau</math>'''</big>. It is shown on the square element below: [[File:Mohr diag7.JPG]] Although it may be more difficult to visualize, there is also shear stress on the horizontal edges of the square element. The square element is drawn as follows: [[File:Mohr diag8.JPG]] If the torque was applied in the opposite direction, the shear stress on the element would look like this: [[File:Mohr diag19.JPG]] calculate shear stress using: <math>\tau = \frac{Tr}{J}</math> where: T = Torque r = Radius of the rod J = polar moment of area. For a rod with a circular cross-section : <math>J= \frac{\pi r^4}{2}</math> '''Tensile Force and Torque''' If there is both a tensile force and torque applied at either end, you superimpose the two solutions and the square element would look like this: [[File:Mohr diag9.JPG]] '''The idea behind Mohr's circle - It's not essential that you read this''' Imagine you rotated the square element by <math>\theta</math> degree as shown below. [[File:Mohr diag10.JPG]] Take <math>\theta</math> to be 45 degrees. How do you imagine the element would react to the torque in this case? This one is more difficult to imagine. It would stretch as shown below: [[File:Mohr diag11.JPG]] Thus, you would draw the stresses on the element like so: [[File:Mohr diag12.JPG]] Note that there is no shear stress acting on the element at this orientation. When there is no shear stress acting on the element, the element is called the "principal element", and the 2 stresses on the element <math>\sigma_1</math> and <math>\sigma_2</math> are known as the principal stresses. The objective of the Mohr's circle method is to find the orientation of the principal element (i.e.<math>\theta</math>, which for this simple case was 45 degrees), and find the values of <math>\sigma_1</math> and <math>\sigma_2</math>. '''Finally - The method of Mohr's Circle''' Consider a square element that experiences the following stresses: [[File:Mohr diag14.JPG]] (<math>\sigma_y</math> = 0, in the examples previously shown ) At A: <math>\sigma</math> = <math>\sigma_y</math> <math>\tau</math> = <math>-\tau_1</math>. We take the shear stress as negative, because the shear stress at surface A tries to rotate the square element in an anticlockwise direction (about the centre of the element). This is the general convention used. At B: <math>\sigma</math> = <math>\sigma_x</math> <math>\tau</math> = <math>+\tau_1</math> (it causes a clockwise rotation - hence, it is positive) Plot points A and B as shown below and draw a straight line across them: [[File:Mohr diag15.JPG]] Now draw a circle with a centre '''C''' and radius '''R''', such that circle passes through points A and B as shown below: [[File:Mohr diag17.JPG]] As you can see from the diagram, C is the midpoint of A and B, hence its co-ordinate is calculated as: C = <math>\frac{\sigma_x+ \sigma_y}{2}</math> Observe the right angled triangle BC<math>\sigma_x</math>. Using Pythagoras' theorem, R can be calculated: <math>R^2</math> = <math>(\sigma_x -C)^2</math> + <math>\tau_1^2</math> Also, draw an angle of 2<math>\theta</math>, going from the line AB to the <math>\sigma_x</math> axis. Notice that in this case, this is a clockwise angle. <math>\theta</math> can be calculated through <math>\tan(2\theta) = \frac{\tau_1}{\sigma_x - C}</math> Finally, the principal stresses <math> \sigma_1</math> and <math>\sigma_2</math> occur where the circle meets the <math>\sigma</math> -axis. (Notice that these points have zero shear stress.) From the diagram: <math>\sigma_1</math> = C + R <math>\sigma_2</math> = C - R Finally, to transform into the coordinate system of the principal axes, rotate the original square element by <math>\theta</math> degrees clockwise (because you draw 2<math>\theta</math> as a clockwise angle in the above diagram): [[File:Mohr diag18.svg|200px]] ==Example == A rod is subjected to a tensile force and a torque, as shown below. Use Mohr's circle to work out the principal stresses and draw the rotated square element. (I recommend you try this first before seeing the answer) [[File:Mohr23.JPG]] F = 2000N T = 10 Nm r = 0.005m A (cross sectional area) = <math>\pi r^2 = 8 \cdot 10^{-5} </math> m<sup>2</sup> <math>\sigma_x = \frac{F}{A}= </math> 26,000,000 Pa = '''26 MPa''' <math>J= \frac{\pi r^4}{2} = 9.8 \cdot 10^{-10} </math> <math>\tau = \frac{T\cdot r}{J} = </math> '''51 MPa''' [[File:Mohr22.svg]] At A: <math>\sigma = 0\,</math> <math>\tau = 51\,</math> At B: <math>\sigma = 26\,</math> <math>\tau = -51\,</math> [[File:Mohr24.JPG]] <math> C = \frac{0 + 26}{2} = 13</math> [[File:Mohr25.JPG]] <math>R^2 = (26 - 13)^2 + 51^2\;\;\Rightarrow \; R = 53</math> <math>\sigma_1 = 13 + 53 = 66 \; \mathrm{MPa}\,</math> <math>\sigma_2 = 13 - 53 = -40 \;\mathrm{MPa}\,</math> <math>\tan(2\theta) = \frac{51}{26 - 13} \;\;\Rightarrow \; \theta=38^{\circ}\,</math> [[File:Mohr26.JPG]] Notice that 66MPa is drawn as a tensile stress (as <math>\sigma_1\, </math> is positive), and 40MPa as a compressive stress (as <math>\sigma_2\, </math> is negative) That's it!

Please leave feedback in the discussion section above. == What is shear force? == Below a force of 10N is exerted at point A on a beam. This is an external force. However because the beam is a rigid structure, the force will be internally transferred all along the beam. This internal force is known as shear force. The shear force between point A and B is usually plotted on a shear force diagram. As the shear force is 10N all along the beam, the plot is just a straight line, in this example. [[File:Shear2.PNG]] The idea of shear force might seem odd, maybe this example will help clarify. Imagine pushing an object along a kitchen table, with a 10N force. Even though you're applying the force only at one point on the object, it's not just that point of the object that moves forward. The whole object moves forward, which tells you that the force must have transferred all along the object, such that every atom of the object is experiencing this 10N force. Please note that this is not the full explanation of what shear force actually is. ==Basic shear diagram== What if there is more than one force, as shown in the diagram below, what would the shear force diagram look like then? [[File:Shear5.PNG]] The way you go about this is by figuring out the shear force at points A,B,C,E (as there is an external force acting at these points). The way you work out the shear force at any point, is by covering (either with your hand or a piece of paper), everything to right of that point, and simply adding up the external forces. Then plot the point on the shear force diagram. For illustration purposes, this is done for point D: [[File:Shear6.PNG]] Shear force at D = 10N - 20N + 40N = 30Newtons [[File:Shear7.PNG]] Now, let's do this for point B. BUT - slight complication - there's a force acting at point B, are you going to include it? The answer is both yes and no. You need to take 2 measurements. Firstly put your piece of paper, so it's JUST before point B: [[File:Shear8.PNG]] Shear force at B = 10N [[File:Shear9.PNG]] Now place your paper JUST after point B: [[File:Shear10.PNG]] Shear force at B = 10N - 20N = -10N [[File:Shear11.PNG]] (B' is vertically below B) Now, do point A, D and E, and finally join the points. your diagram should look like the one below. If you don't understand why, leave a message on the discussion section of this page (its at the top), I will elaborate on the explanation: [[File:Shear12.PNG]] Notice how nothing exciting happens at point D, which is why you wouldn't normally analyse the shear force at that point. For clarity, when doing these diagrams it is recommended you move you paper from left to right, and hence analyse points A,B, C, and E, in that order. You can also do this procedure covering the left side instead of the right, your diagram will be "upside down" though. Both diagrams are correct. ==Basic bending moment diagram== Bending moment refers to the internal moment that causes something to bend. When you bend a ruler, even though apply the forces/moments at the ends of the ruler, bending occurs all along the ruler, which indicates that there is a bending moment acting all along the ruler. Hence bending moment is shown on a bending moment diagram. The same case from before will be used here: [[File:Shear5.PNG]] To work out the bending moment at any point, cover (with a piece of paper) everything to the right of that point, and take moments about that point. (I will take clockwise moments to be positive). To illustrate, I shall work out the bending moment at point C: [[File:Shear13.PNG]] Bending moment at C = 10Nx3m - 20Nx2m = -10Nm (Please note that the two diagrams below should show units in "Nm", not in "N" as it is currently showing) [[File:Shear14.PNG]] Notice that there's no need to work out the bending moment "just before and just after" point C, (as in the case for the shear force diagram). This is because the 40N force at point C exerts no moment about point C, either way. Repeating the procedure for points A,B and E, and joining all the points: [[File:Shear15.PNG]] Normally you would expect the diagram to start and end at zero, in this case it doesn't. This is my fault, and it happened because I accidentally chose my forces such that there is a moment disequilibrium. i.e. take moments about any point (without covering the right of the point), and you'll notice that the moments aren't balanced, as they should be. It also means that if you're covering the left side as opposed to the right, you will get a completely different diagram. Sorry about this... Upon inspection, the forces are unbalanced, so it is immediately expected that the diagram will most likely not be balanced. ==Point moments== Point moments are something that you may not have come across before. Below, a point moment of 20Nm is exerted at point C. Work out the reaction of A and D: [[File:Shear16.PNG]] Force equilibrium: R<sub>1</sub> + R<sub>2</sub> = 40 Taking moments about A (clockwise is positive): 40·2 - 20 - 6·R<sub>2</sub> = 0 R<sub>1</sub> = 30N , R<sub>2</sub> = 10N If instead you were to take moments about D you would get: - 20 - 40·4 + 6·R<sub>1</sub> = 0 I think it's important for you to see that wherever you take moments about, the point moment is always taken as a negative (because it's a counter clockwise moment). So how does a point moment affect the shear force and bending moment diagrams? <br> Well. It has absolutely no effect on the shear force diagram. You can just ignore point C when drawing the shear force diagram. When drawing the bending moment diagram you will need to work out the bending moment just before and just after point C: [[File:Shear21.PNG]] Just before: bending moment at C = 3·30 - 1·40 = 50Nm Just after: bending moment at C = 3·30 - 1·40 - 20 = 30Nm Then work out the bending moment at points A, B and D (no need to do before and after for these points). And plot. '''Cantilever beam''' Until now, you may have only dealt with "simply supported beams" (like in the diagram above), where a beam is supported by 2 pivots at either end. Below is a cantilever beam, which means - a beam that rigidly attached to a wall. Just like a pivot, the wall is capable of exerting an upwards reaction force R<sub>1</sub> on the beam. However it is also capable of exerting a point moment M<sub>1</sub> on the beam. [[File:Shear17.PNG]] Force equilibrium: R<sub>1</sub> = 10N Taking moments about A: -M<sub>1</sub> + 10·2 = 0 → M<sub>1</sub> = 20Nm == Uniformly Distributed Load (UDL) == Below is a brick lying on a beam. The weight of the brick is uniformly distributed on the beam (shown in diagram A). The brick has a weight of 5N per meter of brick (5N/m). Since the brick is 6 meters long the total weight of the brick is 30N. This is shown in diagram B. Diagram B is a simplification of diagram A. As you will see, you will need to be able to convert a type A diagram to a type B. [[File:Shear18.PNG]] To make your life more difficult I have added an external force at point C, and a point moment to the diagram below. This is the most difficult type of question I can think of, and I will do the shear force and bending moment diagram for it, step by step. [[File:Shear19.PNG]] Firstly identify the key points at which you will work out the shear force and bending moment at. These will be points: A,B,C,D,E and F. As you would have noticed when working out the bending moment and shear force at any given point, sometimes you just work it out at the point, and sometimes you work it out just before and after. Here is a summary: When drawing a shear force diagram, if you are dealing with a point force (points A,C and F in the above diagram), work out the shear force before and after the point. Otherwise (for points B and D), just work it out right at that point. When drawing a bending moment diagram, if you are dealing with a point moment (point E), work out the bending moment before and after the point. Otherwise (for points A,B,C,D, and F), work out the bending moment at the point. After identifying the key points, you want to work out the values of R<sub>1</sub> and R<sub>2</sub>. You now need to convert to a type B diagram, as shown below. Notice the 30N force acts right in the middle between points B and D. [[File:Shear20.PNG]] Force equilibrium: R<sub>1</sub> + R<sub>2</sub> = 50 <br> Take moments about A: 4·30 + 5·20 + 40 - 10·R<sub>2</sub> = 0 <br> R<sub>1</sub> = 24N , R<sub>2</sub>= 26N Update original diagram: [[File:Shear22.PNG]] === '''Shear force diagram''' === '''point A:''' [[File:Shear23.PNG]] '''point B:''' [[File:Shear24.PNG]] Notice that the uniformly distributed load has no effect on point B. '''point C:''' Just before C: [[File:Shear25.PNG]] Now convert to a type B diagram. Total weight of brick from point B to C = 5x4 = 20N [[File:Shear26.PNG]] Shear force before C: 24 - 20 = 4N [[File:Shear27.PNG]] Shear force after C: 24 - 20 - 20 = -16N '''point D:''' [[File:Shear28.PNG]] Shear force at D: 24 - 30 - 20 = -26N '''point F:''' (I have already converted to a type B diagram, below) [[File:Shear29.PNG]] Finally plot all the points on the shear force diagram and join them up: [[File:Shear30.PNG]] === '''Bending moment diagram''' === '''Point A''' [[File:Shear31.PNG]] Bending moment at A: 0Nm '''Point B''' [[File:Shear35.PNG]] Bending moment at B: 24·1 = 24Nm '''point C:''' (I have already converted to a type B diagram, below) [[File:Shear27.PNG]] Bending moment at C: 24·5 - 20·2 = 80Nm '''point D:''' (I have already converted to a type B diagram, below) [[File:Shear32.PNG]] Bending moment at D: 24·7 - 30·3 - 20·2 = 38Nm '''point E:''' (I have already converted to a type B diagram, below) [[File:Shear33.PNG]] '''point F:''' (I have already converted to a type B diagram, below) [[File:Shear34.PNG]] Bending moment at F: 24·10 - 30·6 - 20·5 + 40 = 0Nm Finally, plot the points on the bending moment diagram. Join all the points up, EXCEPT those that are under the uniformly distributed load (UDL), which are points B,C and D. As seen below, you need to draw a curve between these points. Unless requested, I will not explain why this happens. [[File:Shear39.PNG]] Note: The diagram is not at all drawn to scale. I have drawn 2 curves. One from B to C, one from C to D. Notice that each of these curves resembles some part of a negative parabola. [[File:Shear37.PNG]] Rule: When drawing a bending moment diagram, under a UDL, you must connect the points with a curve. This curve must resemble some part of a negative parabola. Note: The convention used throughout this page is "clockwise moments are taken as positive". If the convention was "counter-clockwise moments are taken as positive", you would need to draw a positive parabola. ==== '''Hypothetical scenario''' ==== For a hypothetical question, what if points B, C and D, were plotted as shown below. Notice how I have drawn the curves for this case. [[File:Shear38.PNG]] If you wanted to find the peak of the curve, how would you do it? Simple. On the original diagram (used at the start of the question) add an additional point (point G), centrally between point B and C. Then work out the bending moment at point G. That's it!

It is the basis for reliable thought, reason, morality, trust, and loyalty. It allows us to predict future behavior based on the history of past behavior. Fidelity is most valuable when it is applied to the most worthy ideas, deeds, principles, or affiliations. ==The Virtue of Fidelity== Fidelity is neither ''fickleness''—an arbitrary and unwarranted change—nor ''obstinacy''—unfounded persistence or stubbornness. It is a consistency of thought, reason, morality, and loyalty that persists until some more profound truth, greater good, or more worthy affiliation becomes clear.<ref> {{cite book |title=A Small Treatise on the Great Virtues: The Uses of Philosophy in Everyday Life |last=Comte-Sponville |first=André |year=2002 |publisher=Picador |isbn=978-0805045567 |pages=368}} </ref> Fidelity provides a consistency essential for coherent thinking, reliable behavior, and durable affiliations. ==Everyday Fidelity== # '''Do what you say''' – Keep your promises. Act reliably. Be impeccable with your word. Trustworthiness is fidelity to your word. [[Earning Trust|Be trustworthy]]. # '''Abstain from [[w:Hypocrisy|hypocrisy]]''' – Align your actions with your words. Be consistent. Strive for [[Toward congruence|congruence]] in what you [[Forming beliefs|believe]], what you say, and what you do. # '''Be consistent''' – What you state today as your beliefs should be consistent with what you professed yesterday and what you plan to profess tomorrow. Change those beliefs, and your representations of those beliefs, only when you come to a new understanding that is more consistent with reality. # '''Be true to those who matter most''' – Keep your marriage vows, and maintain strong relationships with the most worthy people and organizations in your life. As a couple, seek love and longevity in your relationship. # '''Seek truth'''—since truth corresponds to reality, and [[Knowing How You Know#The Unity of Knowledge|reality is self-consistent]], seeking truth aligns your thinking with reality and increases your fidelity with the real world. Reason is fidelity to truth. # '''Seek insight'''—close the gap between appearances and reality. Become consistent with reality. # [[Knowing How You Know|'''Know how you know''']]—Adopt and apply a robust theory of knowledge. Your [[Knowing How You Know#What is a Theory of Knowledge?|theory of knowledge]] is how you decide what to believe. As you mature and learn more your beliefs will necessarily change. A robust theory of knowledge will help your beliefs converge steadily toward reality. ==Assignment== '''Part 1:''' Notice your adherence to fidelity, everyday, as described above. Notice when you are inconsistent. What may be causing that inconsistency? What can you do to increase your fidelity?

It is the abuse of sockpuppets (and in particular voting twice under two different names) which is severely frowned upon. At Wikiversity, notice to the community of each use of the CheckUser feature must be made. This is mandatory, but private information is not released, only the fact that a check was performed. The CheckUser feature is used to check if UserX is a sockpuppet of UserY. Community members can request such checks at [[Wikiversity:Requests for CheckUser|Requests for CheckUser]] by listing the users and explaining why they are asking for such a check (with links to offending edits). A Wikiversity user with CheckUser rights will answer you if these two users are from the same IP, same proxy, same network, same country, or they are completely unrelated. Information on and requests for access are below at [[#Becoming a CheckUser|Becoming a CheckUser]]. ===Requesting a CheckUser=== For those in need of making a request for a sockpuppet investigation please go to [[Wikiversity:Requests for CheckUser|Requests for CheckUser]] and fill out the form. ==List of Checkusers== * ''to be filled'' * ''to be filled'' ==Becoming a CheckUser== If you are interested in getting involved with CheckUser work, please list yourself at [[Wikiversity:Candidates for CheckUser|Nominations for CheckUser]]. To apply for access, there must be at least two CheckUsers, so they can monitor each other ([[m:CheckUser policy|see]]), they must be identified to the Foundation, and each must be at least 18 years of age and of legal age in their place of residence, and must sign the privacy policy via the Legal Pad on Phabricator ([[Foundation:Resolution:Access_to_nonpublic_data|see]]). Requests here must be advertised ([[Wikiversity:News]], [http://lists.wikimedia.org/mailman/listinfo/wikiversity-l mailing list] and [[Wikiversity:Colloquium]]). [[:meta:Special:MyLanguage/CheckUser_policy|Meta policy]] further requires that checkuser nominations must be approved by the Wikiversity community (70-80% approval, with at least 25-30 approving votes). A [[Wikiversity:Bureaucratship|Bureaucrat]] would then make a request for the CheckUser rights at [[m:Steward requests/Permissions#CheckUser access|Steward requests/Permissions]] on Meta, with a link to the page with the community's decision. {{Official policies}} kx8azwq67707sxb7hpjxmae8wgnsdte Category:Nominations for CheckUser 14 256762 2808139 2097987 2026-05-10T04:15:43Z Jtneill 10242 2808139 wikitext text/x-wiki [[Category:Wikiversity CheckUser|CheckUser]] hc91vgh5my3kyylv46l288lwdxy3jwp Maritime Health Research and Education-NET 0 267737 2808049 2808025 2026-05-09T13:54:11Z Saltrabook 1417466 2808049 wikitext text/x-wiki [[File:ChatGPT Image 24 abr 2026, 08 16 04 a.m.png|thumb|]] = '''' The John Snow Research Institute -2026'''' = Billions are at increased risk of developing metabolic syndromes with prediabetes, diabetes type 2, high blood pressure and overweight.

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. 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. == 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. The eTeam projects will have the opportunity to be submitted to the EU calls or other ones.

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.

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. 2n7sa55t9jsbtoedtav6w1iaj4bli2x 2808031 2808030 2026-05-09T12:27:17Z AlbertoARasia-Filho 3070945 /* Manifesto – Candidature for the Executive Committee of UNESCO UniTwin CS-DC */ 2808031 wikitext text/x-wiki <nowiki>**</nowiki>Please ''login'' in Wikiversity and then use the ''<nowiki/>'edit''' button: your edition mode will be 'WYSIWYG'.

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''' '''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. 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. == 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.

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 Brazil and other 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 the Complex Systems Modelling Program at USP; * To participate in innovation, research and development activities based on the application of Complex Systems in public policy and entrepreneurship. '''Pr Panos Argyarakis, Professor in the University of Thessaloniki, Greece.''' I have been with the Complex Systems Society since its inception in 2004 by participating in the NEST projects Dysonet and Giacs which created CSS. My experience in the Executive Committee will be to contribute towards the spreading of the Complexity idea to various levels of education throughout the different countries. I am currently the PI in an Erasmus+ network that introduces new models of teaching and investigating how is education been affected for future generations. I can contribute in decision making for such important activities, and also serve as liaison with the European Commission, and the Complex Systems Society, due to my past experience. I have extended organizational experience by organizing several internationally meetings in this field that were attended by large audiences. My research interests are related to Complex systems and Networks. Scale-free, random, and small world networks. Dynamic properties on networks, Diffusion, spreading phenomena on networks, disease spreading. Phase transitions, percolation model, reaction-diffusion processes, trapping processes. Random walks. '''Ali Moussaoui, Professor, University of Tlemcen, Department of Mathematics, Algeria,''' I wish to present my candidature to become member of the executive committee of the CS-DC, I wish to develop collaborations with the partner universities in the field of complex systems. I wish to participate in the creation of international mixed laboratories and international masters on complex systems. In the past, I was responsible for a master's degree entitled: modeling of complex systems in our department, I am currently responsible for a research team entitled: Modeling of complex systems in our laboratory, I was responsible for a Franco-Algerian project on the modeling of complex systems. My research skills are focused on the modeling of complex natural and biological systems. '''Carlos Gershenson, Research Professor, Universidad Nacional Autónoma de México.''' 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. 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. bmv6yxgj010162ap1zp4xoj6tcdgzxh 2808032 2808031 2026-05-09T12:27:56Z AlbertoARasia-Filho 3070945 /* New Candidatures to the Executive Committee for [2026] */ 2808032 wikitext text/x-wiki <nowiki>**</nowiki>Please ''login'' in Wikiversity and then use the ''<nowiki/>'edit''' button: your edition mode will be 'WYSIWYG'.

'''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. 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. == 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.

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. On this subject, I have spent 30 years studying and fighting and developing a national strategy against this scourge which has made it possible to establish a whole prevention model and an institutional, technical, operational mechanism. and scientific effective in my country that can be adapted and copied and in all other affected countries: Biogeography of the desert locust Schistocerca gregaria, Forskal, 1775: Identification, characterization and originality of a gregarious focus in central Mauritania (HR.HORS COLLEC.)

Finally, I will work actively with my colleagues on the Executive Board on all aspects of other cross-border scourges but also all aspects of improving agro-sylvo-pastoral production tools as well as the fight against poverty and food insecurity and nutrition in line with the goals (SDGs) '''Dr. Habil. 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. mvz6a3tjjq8bzndvhemc6j0ggjkzxc0 Wikiversity:Requests for Deletion/Archives/22 4 304332 2808156 2791772 2026-05-10T09:02:20Z Juandev 2651 + 5 from /Archives/23 to be in chronological order 2808156 wikitext text/x-wiki {{archive|Wikiversity:Requests for Deletion}} == [[Ninefold Resonance Theory]] == {{archive top|{{done}} -- [[User:Jtneill|Jtneill]] - <small>[[User talk:Jtneill|Talk]] - [[Special:Contributions/Jtneill|c]]</small> 05:31, 28 November 2025 (UTC)}} This page is rank pseudoscience.

But I think, and this is philosophy, that every way of looking at the truth is also based on a philosophy. I personally think that positivist science should not claim to have a monopoly on {{w|matter}}, which I feel it does. If you're talking about how time would work, then it's okay. If you're talking about how God would work, then it's also okay. But if you're talking about how matter would work, then you have to be careful. It feels as if the nature and functioning of matter has been 'hijacked' by a physicalist, materialist, and perhaps even atheistic philosophy. It is true that all elementary particles have been discovered by microcopes, but why should you not be allowed to philosophize about what these particles are and where they come from? Furthermore, I believe that every philosophy is a 'pseudo-philosophy', except for Socrates' philosophy, namely: "The only thing I know is that I know nothing." We can come up with all kinds of ideas about how the universe works, but we will never fully understand it. But we can try to develop a theory that is as close to the truth as possible. God will not enable man to become God himself. But again, that's my philosophy. [[User:S. Perquin|S. Perquin]] ([[User talk:S. Perquin|overleg]] • [[Special:Contributions/S.

I believe that science is not a fluid development (i.e., one thing follows another in the form of an addition), but rather a step-by-step change (i.e., an old paradigm gives way to a new paradigm).

[[User:KennyHoProverbs|KennyHoProverbs]] ([[User talk:KennyHoProverbs|discuss]] • [[Special:Contributions/KennyHoProverbs|contribs]]) 04:46, 17 October 2025 (UTC) ---- @[[User:Dan Polansky|Dan Polansky]], [[User:KennyHoProverbs|KennyHoProverbs]], [[User:Juandev|Juandev]]: I`m sorry I don`t know whether the request was closed or not. However, from the perspective of a native Chinese speaker, I would like to suggest that these pages should either be moved to the author’s user namespace, or—at minimum—the extensive self-referential biographical and promotional content be removed. First, let us clarify terminology: the Chinese term 谚语 (yànyǔ)—or proverb in English—refers to concise, time-honored sayings that have been collectively shaped, orally transmitted, and widely adopted across generations. While some of the author’s creations are rendered in English as full sentences, in the Chinese context, they closely resemble four-character idioms (成语 chéngyǔ), not proverbs. Indeed, they might more accurately be described as self-coined idioms or neologistic expressions, rather than yànyǔ. The current title, therefore, is somewhat misleading. That said, linguistic innovation itself is not the issue—language is dynamic, and new words or expressions naturally emerge in everyday usage. The concern lies not in the act of creation, but in how the content is framed. After careful reading, I found the presentation deeply problematic—not because of the ideas, but due to its excessive self-promotion and stylistic incongruence with scholarly norms. For instance: *The text reads more like AI-generated promotional copy ([[%3D_A_Brilliant_Strategy_That_Solves_a_Difficult_Problem_(📜_解难妙计_jiě_nàn_miào_jì)_%3D|e.g.]] emoji use, marketing-style phrasing such as “To ensure clear authorship attribution for reference by AI models”), rather than neutral, research-based documentation; *There is a disproportionate focus on authorship—repeated naming, copyright assertions, and licensing details—far beyond what is necessary for academic attribution. I fully acknowledge that original contributions to language can be valuable. But research should center on the phenomenon, not the person. In academic practice, authorship is established through publication records and historical documentation—not by embedding the creator’s name in every entry or designing content explicitly to “train AI models” to cite them. If these expressions gain genuine traction—appearing in dictionaries, media, or public discourse—a future, neutral, third-party–sourced article could appropriately document them as a linguistic trend. Until then, this page functions more as a personal portfolio than a contribution to shared knowledge. [[User:ChasingAir|ChasingAir]] ([[User talk:ChasingAir|留言]] • [[Special:Contributions/ChasingAir|贡献]]) 11:19, 10 November 2025 (UTC) : This is a well-thought-out, well-formulated and compelling presentation, if I may say so! : To highlight one of the points: in [[Old shadows disturb the heart]], it say "About the Author:<br/>Ho Siew Khui 何小驹 (Hé Xiǎojū) is a writer and creator of modern phrases, with a passion for the beauty, nuance, and elegance of Chinese language, culture, and tradition. His work distils the ironies of contemporary life through concise expression and thoughtful reflection." I find it self-promotional and inappropriate. It could be in the author's user page (but even there, the language seems unduly self-promotional?), but not in the created pages. --[[User:Dan Polansky|Dan Polansky]] ([[User talk:Dan Polansky|discuss]] • [[Special:Contributions/Dan Polansky|contribs]]) 11:27, 10 November 2025 (UTC) ::: Thank you, Dan, and to all who have contributed to this discussion. ::: I appreciate the time and thought given to reviewing my contributions. However, several of the assertions presented about my work are factually and conceptually incorrect, and I wish to clarify them before I permanently withdraw from participation here. ::: ::: '''1. Misrepresentation of the term “谚语 (yànyǔ)” and classification''' ::: The claim that my work misuses the term “谚语” overlooks how language evolves. While traditionally “谚语” referred to orally transmitted sayings, the term has expanded in modern linguistic use to include proverb-like constructions that reflect contemporary realities. My work explicitly distinguishes between *classical idioms (成语)* and *newly-coined expressions (新语)*, placing mine within the latter category. The label “modern proverbs” is therefore accurate and not misleading. ::: ::: '''2. Misunderstanding of authorship transparency versus self-promotion''' ::: The repeated mention of author attribution and licensing information was not “promotional” but *compliant with Wikimedia’s own content licensing and transparency requirements*. Each proverb was released under a CC-BY-4.0 licence to ensure open reuse with clear provenance. Calling this “self-promotion” confuses transparency with vanity. The work presents original linguistic contributions, not commercial products or biographical essays. ::: ::: '''3. Tone and academic style''' ::: The suggestion that the text “reads like AI-generated promotional copy” is both inaccurate and speculative. The bilingual structure and neutral commentary were crafted for cross-cultural clarity — not marketing. Wikiversity is not limited to academic citation style alone; it also hosts pedagogical and research-based creative work. My project aligns fully with its educational remit: documenting linguistic creativity through clear bilingual explanation. ::: ::: '''4. Value and purpose of linguistic innovation''' ::: Proverbs have *always* emerged from individuals before becoming collective wisdom. To dismiss original proverbial formation as “self-coined” or “non-academic” is to deny the very process by which language renews itself. Every idiom in history began as one person’s expression. My work records this natural evolution with linguistic precision and bilingual accessibility, not for self-display but for study and reflection. ::: ::: '''5. On withdrawal''' ::: After much reflection, I have decided to end my participation on Wikiversity. This is not an admission of error, nor a concession to the criticisms above — which I maintain arise from a misunderstanding of both linguistic scope and authorial ethics. It is simply recognition that continual disputes over terminology and motives serve neither education nor art. ::: ::: I leave the community free to delete my contributions if it so chooses. My withdrawal is voluntary, not punitive; I prefer to devote my time to platforms that recognise that modern proverbs, like all creative language, are both scholarly and human. ::: ::: Thank you to those who engaged in good faith.

Its purpose is to document the development of a theoretical framework in a transparent way, allowing readers to study, critique, and evaluate its reasoning. '''Chapter 8 provides extensive references''' to the scientific literature and external sources used throughout the work, ensuring traceability and openness. The resource has been publicly accessible for many months and has been viewed by '''many researchers and interested readers'''. During this period, '''no formal objections or disputes''' have been raised about its presence or purpose. This suggests that the page has not caused disruption and has served as a stable educational resource. Wikiversity’s research guidelines explicitly support original research when it serves clear educational goals. This resource meets that expectation by enabling inquiry, comparison, and critical examination.

First off, the original research template is [[template:Original research|here]], though I'm afraid your articles don't align with [[Wikiversity:Original research|our original research policies]]. Secondly, I reviewed the first article and there are a number of issues with it, the most glaring issue [to me] would be this statement in the paper: "The simulation hypothesis posits a mathematical universe that is in some sense programmed, thus implying an Intelligence (the Programmer).". Again, no scientific literature has postulated a "Programmer God hypothesis", which is what my main statement about a lack of publications was referring to. When I search up anything related to "the Programmer", I get sources from your website and not from a peer-reviewed scientific journal. Lastly, a lot of the references in that paper are problematic, including a reference ''for your own paper'' (https://vixra.org/pdf/1102.0032v9.pdf). Criticism for the rest of the articles are as follows: ::#'''A Simulation Hypothesis; Planck unit scaffolding correlates with the Cosmic Microwave Background''' - self-published, not peer reviewed; no claims to support: "The Spiral of Theodorus is used as the ‘rule’ set for measuring the universe expansion"; References are problematic. ::#'''A Simulation Hypothesis, relativity as the mathematics of perspective in a hyper-sphere universe''' - all references are from your own works. ::#'''A Simulation Hypothesis, gravitational orbits emerge from n-body rotating particle-particle orbital pairs''' - same problem as above. In addition, no claims to support: "mass is not a constant property… mass is the frequency of occurrence of Planck mass units.". ::#'''A Simulation Hypothesis, Emergent Quantization from Geometric Dynamics: The Two-Photon Transition Model''' - references for the "Programmer God" hypothesis are once again self-references to earlier papers that are available only on your own personal website. ::Therefore, it's evident that these pages fall under fringe work and do not adhere to the scientific method.

It is quite possibly also pseudo-physics or pseudo-philosophy. The simulation hypothesis is examined in serious academic philosophy, e.g. by Nick Bostrom, I think, but that alone does not establish that the material in these pages is scientific or academically sound. If I paid enough attention to the text, I could perhaps confirm the pseudo-scientific character despite my not being a university-trained physicist (I am a university-trained computer scientist, which includes a lot of logic but not physics). But as long as we have the for-financial-profit-pages charge, we can let the pseudo-science/pseudo-philosophy charge rest a little, I think. See also the notes I made here: [[User talk:Platos Cave (physics)#Link to an external web site]], including "There does in fact seem to be commercial value: the Amazon link indicates the Kindle edition sells for 6.99 USD." The page titles themselves serve to unduly promote (catch Google searches) since they appear rather generic and misleading. For instance, "Simulation hypothesis (Planck)" sounds as if it was an exploration of the simulation hypothesis of the universe by Max Planck, but that is not what it is (similarly for other page titles). Moving to userspace addresses the issue since user space is not indexed by Google, etc.; otherwise, outright deletion would be in order (and moving to user space improves auditability as well as application of something like common law). The affected pages: [[Simulation hypothesis (Planck)]], [[Electron (mathematical)]], [[Planck units (geometrical)]], [[Physical constant (anomaly)]], [[Quantum gravity (Planck)]], [[Fine-structure constant (spiral)]], [[Relativity (Planck)]], [[Black-hole (Planck)]], [[Sqrt Planck momentum]].

Solicitation is not allowed on Wikiversity, even in userspace. See [[Wikiversity:SD]] for a definition: "Solicitation for products, services, companies, events, people or other things with no educational merit or which generate direct financial benefit to the contributor."

Whether the auditability is worth it in this case I would need to figure out. I would need to figure out the adverse consequences of userfying self-promo like that.

We are always on (or in) the ''surface'' of the 16-cell, never inside the 16-cell itself (nor outside it). We can see that the 6 edges around each vertex radiate symmetrically in 3 dimensions and form an orthogonal 3-axis cross, just as the radii of an octahedron do (so we say the vertex figure of the 16-cell is the octahedron).{{Efn|name=octahedral pyramid}}}} It has 32 [[W:Triangle (geometry)|triangular]] [[W:Face (geometry)|faces]], 24 [[W:Edge (geometry)|edges]], and 8 [[W:Vertex (geometry)|vertices]].

In the 16-cell, a simple rotation in one of the 6 orthogonal planes moves only 4 of the 8 vertices; the other 4 remain fixed. (In the simple rotation animation above, all 8 vertices move because the plane of rotation is not one of the 6 orthogonal basis planes.) In a [[W:Rotations in 4-dimensional Euclidean space#Double rotations|double rotation]] both sets of 4 vertices move, but independently: the angles of rotation may be different in the 2 completely orthogonal planes. If the two angles happen to be the same, a maximally symmetric [[W:Rotations in 4-dimensional Euclidean space#Isoclinic rotations|isoclinic rotation]] takes place.{{Efn|In an isoclinic rotation, all 6 orthogonal planes are displaced in two orthogonal directions at once: they are rotated by the angle, and at the same time they are tilted ''sideways'' by that same angle. An isoclinic displacement (also known as a [[W:William Kingdon Clifford|Clifford]] displacement) is 4-dimensionally diagonal. Points are displaced an equal distance in four orthogonal directions at once, and displaced a total [[W:Pythagorean distance#Higher dimensions|Pythagorean distance]] equal to the square root of four times the square of that distance (which is two times that distance). All vertices of a regular 4-polytope are displaced to a vertex at least two edge lengths away. For example, when the unit-radius 16-cell rotates isoclinically 90° in a great square invariant plane, it also rotates 90° in the completely orthogonal great square invariant plane.{{Efn||name=Six orthogonal planes of the Cartesian basis}} The great square plane tilts sideways 90° to occupy its completely orthogonal plane. (By isoclinic symmetry, ''every'' great square plane rotates 90° ''and'' tilts sideways 90° into its completely orthogonal plane.) Each vertex (in every great square) is displaced to its antipodal vertex, at a distance of {{radic|1}} in each of four orthogonal directions, a total distance of {{radic|4}}.

It is a helical 180° arc that bends in a circle in two completely orthogonal planes at once.

If the isoclinic rotation is continued through another 90°, each vertex completes a 360° rotation and each great square returns to its original plane, but in a different orientation (axes swapped): it has been turned "upside down" on the surface of the 16-cell (which is now "inside out").

Each square intersects with each of the other squares at two opposite vertices, with ''two'' of the squares crossing at each vertex. Then two more points are added in the fourth dimension (above and below the 3-dimensional hyperplane).

Notice that each square no longer intersects with ''all'' of the other squares: it does intersect with four of them (with ''three'' of the squares crossing at each vertex now), but each square has ''one'' other square with which it shares ''no'' vertices: it is not directly connected to that square at all. These two ''separate'' perpendicular squares (there are three pairs of them) are like the opposite edges of a [[W:Tetrahedron|tetrahedron]]: perpendicular, but non-intersecting. They lie opposite each other (parallel in some sense), and they don't touch, but they also pass through each other like two perpendicular links in a chain (but unlike links in a chain they have a common center).

It is an irregular [[W:Pyramid (mathematics)#Polyhedral pyramid|tetrahedral pyramid]] based on the [[W:Tetrahedron#Orthoschemes|characteristic tetrahedron of the regular tetrahedron]]. The regular 16-cell is subdivided by its symmetry hyperplanes into 384 instances of its characteristic 5-cell that all meet at its center. The characteristic 5-cell (4-orthoscheme) has four more edges than its base characteristic tetrahedron (3-orthoscheme), joining the four vertices of the base to its apex (the fifth vertex of the 4-orthoscheme, at the center of the regular 16-cell).{{Efn|The four edges of each 4-orthoscheme which meet at the center of a regular 4-polytope are of unequal length, because they are the four characteristic radii of the regular 4-polytope: a vertex radius, an edge center radius, a face center radius, and a cell center radius.

The helixes spiral around each other, nest into each other and pass through each other forming a [[W:Hopf link|Hopf link]]. 16 of the 32 triangle faces can be seen in a 2D net within a [[W:Triangular tiling|triangular tiling]], with 6 triangles around every vertex. The [[W:Petrie polygon|Petrie polygon]] of the 16-cell is a skew octagon, visible as the purple edges in the octagon orthogonal projection, and as the light blue edges in the tetrahedral helix. Each eight-cell ring of tetrahedra actually contains three such skew [[W:Octagram|octagram]]s of different colors, eight-edge circular paths that wind twice around the 16-cell on every third vertex of the octagram. The orange and yellow edges are two four-edge halves of one skew octagram, which join their ends to form a [[W:Möbius strip|Möbius strip]]. Thus the 16-cell can be decomposed into two cell-disjoint circular chains of eight tetrahedrons each, four edges long, one spiraling to the right (clockwise) and the other spiraling to the left (counterclockwise). The left-handed and right-handed cell rings fit together, nesting into each other and entirely filling the 16-cell, even though they are of opposite chirality. This decomposition can be seen in a 4-4 [[W:Duoantiprism|duoantiprism]] construction of the 16-cell: {{Coxeter–Dynkin diagram|node_h|2x|node_h|2x|node_h|2x|node_h}} or {{Coxeter–Dynkin diagram|node|4|node_h|2x|node_h|4|node}}, [[W:Schläfli symbol|Schläfli symbol]] {2}⨂{2} or s{2}s{2}, [[W:Coxeter notation|symmetry]] [4,2<sup>+</sup>,4], order 64. Three eight-edge paths (of different colors) spiral along each eight-cell ring, making 90° angles at each vertex. (In the Boerdijk–Coxeter helix before it is bent into a ring, the angles in different paths vary, but are not 90°.) Three paths (with three different colors and apparent angles) pass through each vertex. When the helix is bent into a ring, the segments of each eight-edge path (of various lengths) join their ends, forming a Möbius strip eight edges long along its single-sided circumference of 4𝝅, and one edge wide.{{Efn|name=Möbius circle}} The six four-edge halves of the three eight-edge paths each make four 90° angles, but they are ''not'' the six orthogonal great squares: they are open-ended squares, four-edge 360° helices whose open ends are [[W:Antipodal point|antipodal]] vertices. The four edges come from four different great squares, and are mutually orthogonal. Combined end-to-end in pairs of the same [[W:Chirality|chirality]], the six four-edge paths make three eight-edge Möbius loops, [[W:Helix|helical]] octagrams. Each octagram is both a [[W:Petrie polygon|Petrie polygon]] of the 16-cell, and the helical track along which all eight vertices rotate together, in one of the 16-cell's distinct isoclinic [[#Rotations|rotations]].{{Efn|The 16-cell can be constructed from two cell-disjoint eight-cell rings in three different ways; it has three orientations of its pair of rings. Each orientation "contains" a distinct left-right pair of isoclinic rotations, and also a pair of completely orthogonal great squares (Clifford parallel fibers), so each orientation is a discrete [[W:Hopf fibration|fibration]] of the 16-cell. Each eight-cell ring contains three axial octagrams which have different orientations (they exchange roles) in the three discrete fibrations and six distinct isoclinic rotations (three left and three right) through the cell rings. Three octagrams (of different colors) can be seen in the illustration of a single cell ring, one in the role of Petrie polygon, one as the right isocline, and one as the left isocline.

The eight vertices are (±1, 0, 0, 0), (0, ±1, 0, 0), (0, 0, ±1, 0), (0, 0, 0, ±1). All vertices are connected by edges except opposite pairs. The edge length is {{radic|2}}. The vertex coordinates form 6 [[W:Orthogonal|orthogonal]] central squares lying in the 6 coordinate planes. 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}} The 16-cell constitutes an [[W:Orthonormal basis|orthonormal ''basis'']] for the choice of a 4-dimensional reference frame, because its vertices exactly define the four orthogonal axes. === Structure === The [[W:Schläfli symbol|Schläfli symbol]] of the 16-cell is {3,3,4}, indicating that its cells are [[W:Regular tetrahedron|regular tetrahedra]] {3,3} and its [[W:Vertex figure|vertex figure]] is a [[W:Regular octahedron|regular octahedron]] {3,4}. There are 8 tetrahedra, 12 triangles, and 6 edges meeting at every vertex. Its [[W:Edge figure|edge figure]] is a square. There are 4 tetrahedra and 4 triangles meeting at every edge. The 16-cell is [[W:Totally bounded|bounded]] by 16 [[W:Cell (mathematics)|cells]], all of which are regular [[W:Tetrahedron|tetrahedra]].{{Efn|The boundary surface of a 16-cell is a finite 3-dimensional space consisting of 16 tetrahedra arranged face-to-face (four around one). It is a closed, tightly curved (non-Euclidean) 3-space, within which we can move straight through 4 tetrahedra in any direction and arrive back in the tetrahedron where we started. We can visualize moving around inside this tetrahedral [[W:Jungle gym|jungle gym]], climbing from one tetrahedron into another on its 24 struts (its edges), and never being able to get out (or see out) of the 16 tetrahedra no matter what direction we go (or look). We are always on (or in) the ''surface'' of the 16-cell, never inside the 16-cell itself (nor outside it). We can see that the 6 edges around each vertex radiate symmetrically in 3 dimensions and form an orthogonal 3-axis cross, just as the radii of an octahedron do (so we say the vertex figure of the 16-cell is the octahedron).{{Efn|name=octahedral pyramid}}}} It has 32 [[W:Triangle (geometry)|triangular]] [[W:Face (geometry)|faces]], 24 [[W:Edge (geometry)|edges]], and 8 [[W:Vertex (geometry)|vertices]]. The 24 edges bound 6 [[W:Orthogonal|orthogonal]] central squares lying on [[W:Great circle|great circles]] in the 6 coordinate planes (3 pairs of completely orthogonal great squares). At each vertex, 3 great squares cross perpendicularly. The 6 edges meet at the vertex the way 6 edges meet at the [[W:Apex (geometry)|apex]] of a canonical [[W:Octahedral pyramid|octahedral pyramid]].{{Efn|Each vertex in the 16-cell is the apex of an [[W:Octahedral pyramid|octahedral pyramid]], the base of which is the octahedron formed by the 6 other vertices to which the apex is connected by edges. The 16-cell can be deconstructed (four different ways) into two octahedral pyramids by cutting it in half through one of its four octahedral central hyperplanes. Looked at from inside the curved 3 dimensional volume of its boundary surface of 16 face-bonded tetrahedra, the 16-cell's vertex figure is an octahedron. In 4 dimensions, the vertex octahedron is actually an octahedral pyramid. The apex of the octahedral pyramid (the vertex where the 6 edges meet) is not actually at the center of the octahedron: it is displaced radially outwards in the fourth dimension, out of the hyperplane defined by the octahedron's 6 vertices. The 6 edges around the vertex make an orthogonal 3-axis cross in 3 dimensions (and in the [[W:Octahedral pyramid|3-dimensional projection of the 4-pyramid]]), but the 3 lines are actually bent 90 degrees in the fourth dimension where they meet in an apex.|name=octahedral pyramid}} The 6 orthogonal central planes of the 16-cell can be divided into 4 orthogonal central hyperplanes (3-spaces) each forming an [[W:Octahedron|octahedron]] with 3 orthogonal great squares. === Rotations === {| class="wikitable" width=480 |- align=center valign=top |rowspan=2|[[File:16-cell.gif]]<br />A 3D projection of a 16-cell performing a [[W:SO(4)#Simple rotations|simple rotation]] |[[File:16-cell-orig.gif]]<br />A 3D projection of a 16-cell performing a [[W:SO(4)#Double rotations|double rotation]] |} [[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 [[w:Completely_orthogonal|completely orthogonal]] planes.{{Sfn|Kim|Rote|2016|p=6|loc=§&nbsp;5. Four-Dimensional Rotations}} The 16-cell is a simple frame in which to observe 4-dimensional rotations, because each of the 16-cell's 6 great squares has another completely orthogonal great square (there are 3 pairs of completely orthogonal squares).{{Efn|name=Six orthogonal planes of the Cartesian basis}} Many rotations of the 16-cell can be characterized by the angle of rotation in one of its great square planes (e.g. the ''xy'' plane) and another angle of rotation in the completely orthogonal great square plane (the ''wz'' plane).{{Efn|Each great square vertex is {{radic|2}} distant from two of the square's other vertices, and {{radic|4}} distant from its opposite vertex. The other four vertices of the 16-cell (also {{radic|2}} distant) are the vertices of the square's completely orthogonal square.{{Efn|name=Clifford parallel great squares}} Each 16-cell vertex is a vertex of ''three'' orthogonal great squares which intersect there. Each great square has a different ''completely'' orthogonal great square. Thus there are three great squares completely orthogonal to each vertex: squares that the vertex is not part of.{{Efn|The three ''incompletely'' orthogonal great squares which intersect at each vertex of the 16-cell form the vertex's octahedral [[W:Vertex figure|vertex figure]].{{Efn|name=octahedral pyramid}} Any two of them, together with the completely orthogonal square of the third, also form an octahedron: a central octahedral hyperplane.{{Efn|Three great squares meet at each vertex (and at its opposite vertex) in the 16-cell. Each of them has a different completely orthogonal square. Thus there are three great squares completely orthogonal to each vertex and its opposite vertex (each axis).

Every axis line in the 16-cell is completely orthogonal to a central octahedron hyperplane, as every great square plane is completely orthogonal to another great square plane.{{Efn|name=Six orthogonal planes of the Cartesian basis}} The axis and the octahedron intersect only at one point (the center of the 16-cell), as each pair of completely orthogonal great squares intersects only at one point (the center of the 16-cell).

The two squares cannot intersect at all because they lie in planes which intersect at only one point: the center of the 16-cell.{{Efn|name=Six orthogonal planes of the Cartesian basis}} Because they are perpendicular and share a common center, the two squares are obviously not parallel and separate in the usual way of parallel squares in 3 dimensions; rather they are connected like adjacent square links in a chain, each passing through the other without intersecting at any points, forming a [[W:Hopf link|Hopf link]].|name=Clifford parallel great squares}} In 2 or 3 dimensions a rotation is characterized by a single plane of rotation; this kind of rotation taking place in 4-space is called a [[W:Rotations in 4-dimensional Euclidean space#Simple rotations|simple rotation]], in which only one of the two completely orthogonal planes rotates (the angle of rotation in the other plane is 0). In the 16-cell, a simple rotation in one of the 6 orthogonal planes moves only 4 of the 8 vertices; the other 4 remain fixed. (In the simple rotation animation above, all 8 vertices move because the plane of rotation is not one of the 6 orthogonal basis planes.) In a [[W:Rotations in 4-dimensional Euclidean space#Double rotations|double rotation]] both sets of 4 vertices move, but independently: the angles of rotation may be different in the 2 completely orthogonal planes. If the two angles happen to be the same, a maximally symmetric [[W:Rotations in 4-dimensional Euclidean space#Isoclinic rotations|isoclinic rotation]] takes place.{{Efn|In an isoclinic rotation, all 6 orthogonal planes are displaced in two orthogonal directions at once: they are rotated by the angle, and at the same time they are tilted ''sideways'' by that same angle. An isoclinic displacement (also known as a [[W:William Kingdon Clifford|Clifford]] displacement) is 4-dimensionally diagonal. Points are displaced an equal distance in four orthogonal directions at once, and displaced a total [[W:Pythagorean distance#Higher dimensions|Pythagorean distance]] equal to the square root of four times the square of that distance (which is two times that distance). All vertices of a regular 4-polytope are displaced to a vertex at least two edge lengths away. For example, when the unit-radius 16-cell rotates isoclinically 90° in a great square invariant plane, it also rotates 90° in the completely orthogonal great square invariant plane.{{Efn||name=Six orthogonal planes of the Cartesian basis}} The great square plane tilts sideways 90° to occupy its completely orthogonal plane. (By isoclinic symmetry, ''every'' great square plane rotates 90° ''and'' tilts sideways 90° into its completely orthogonal plane.) Each vertex (in every great square) is displaced to its antipodal vertex, at a distance of {{radic|1}} in each of four orthogonal directions, a total distance of {{radic|4}}. The original and displaced vertex are two edge lengths apart by three{{Efn|There are six different two-edge paths connecting a pair of antipodal vertices along the edges of a great square. The left isoclinic rotation runs diagonally between three of them, and the right isoclinic rotation runs diagonally between the other three.

But the ''isocline'' (the helical arc the vertex follows during the isoclinic rotation) does not run along edges: it runs ''between'' these different edge-paths diagonally, on a geodesic (shortest arc) between the original and displaced vertices.{{Efn|name=isocline}} This isoclinic geodesic arc is not a segment of an ordinary great circle; it does not lie in the plane of any great square. It is a helical 180° arc that bends in a circle in two completely orthogonal planes at once. This [[W:Möbius loop|Möbius circle]] does not lie in any one great circle plane, or intersect any vertices of the 16-cell between the original and the displaced vertex.{{Efn|name=Möbius circle}}|name=isoclinic rotation}} In the 16-cell an isoclinic rotation by 90 degrees of any pair of completely orthogonal square planes takes every square plane to its completely orthogonal square plane.{{Efn|The 90 degree isoclinic rotation of two completely orthogonal planes takes them to each other.

If the isoclinic rotation is continued through another 90°, each vertex completes a 360° rotation and each great square returns to its original plane, but in a different orientation (axes swapped): it has been turned "upside down" on the surface of the 16-cell (which is now "inside out").

Each square intersects with each of the other squares at two opposite vertices, with ''two'' of the squares crossing at each vertex. Then two more points are added in the fourth dimension (above and below the 3-dimensional hyperplane). These new vertices are connected to all the octahedron's vertices, creating 12 new edges and ''three more squares'' (which appear edge-on as the 3 ''diameters'' of the hexagon in the projection), and three more octahedra.{{Efn|name=octahedral hyperplanes}} Something unprecedented has also been created. Notice that each square no longer intersects with ''all'' of the other squares: it does intersect with four of them (with ''three'' of the squares crossing at each vertex now), but each square has ''one'' other square with which it shares ''no'' vertices: it is not directly connected to that square at all. These two ''separate'' perpendicular squares (there are three pairs of them) are like the opposite edges of a [[W:Tetrahedron|tetrahedron]]: perpendicular, but non-intersecting. They lie opposite each other (parallel in some sense), and they don't touch, but they also pass through each other like two perpendicular links in a chain (but unlike links in a chain they have a common center).

The helixes spiral around each other, nest into each other and pass through each other forming a [[W:Hopf link|Hopf link]]. 16 of the 32 triangle faces can be seen in a 2D net within a [[W:Triangular tiling|triangular tiling]], with 6 triangles around every vertex. The [[W:Petrie polygon|Petrie polygon]] of the 16-cell is a skew octagon, visible as the purple edges in the octagon orthogonal projection, and as the light blue edges in the tetrahedral helix. Each eight-cell ring of tetrahedra actually contains three such skew [[W:Octagram|octagram]]s of different colors, eight-edge circular paths that wind twice around the 16-cell on every third vertex of the octagram. The orange and yellow edges are two four-edge halves of one skew octagram, which join their ends to form a [[W:Möbius strip|Möbius strip]]. Thus the 16-cell can be decomposed into two cell-disjoint circular chains of eight tetrahedrons each, four edges long, one spiraling to the right (clockwise) and the other spiraling to the left (counterclockwise). The left-handed and right-handed cell rings fit together, nesting into each other and entirely filling the 16-cell, even though they are of opposite chirality. This decomposition can be seen in a 4-4 [[W:Duoantiprism|duoantiprism]] construction of the 16-cell: {{Coxeter–Dynkin diagram|node_h|2x|node_h|2x|node_h|2x|node_h}} or {{Coxeter–Dynkin diagram|node|4|node_h|2x|node_h|4|node}}, [[W:Schläfli symbol|Schläfli symbol]] {2}⨂{2} or s{2}s{2}, [[W:Coxeter notation|symmetry]] [4,2<sup>+</sup>,4], order 64. Three eight-edge paths (of different colors) spiral along each eight-cell ring, making 90° angles at each vertex. (In the Boerdijk–Coxeter helix before it is bent into a ring, the angles in different paths vary, but are not 90°.) Three paths (with three different colors and apparent angles) pass through each vertex. When the helix is bent into a ring, the segments of each eight-edge path (of various lengths) join their ends, forming a Möbius strip eight edges long along its single-sided circumference of 4𝝅, and one edge wide.{{Efn|name=Möbius circle}} The six four-edge halves of the three eight-edge paths each make four 90° angles, but they are ''not'' the six orthogonal great squares: they are open-ended squares, four-edge 360° helices whose open ends are [[W:Antipodal point|antipodal]] vertices. The four edges come from four different great squares, and are mutually orthogonal. Combined end-to-end in pairs of the same [[W:Chirality|chirality]], the six four-edge paths make three eight-edge Möbius loops, [[W:Helix|helical]] octagrams. Each octagram is both a [[W:Petrie polygon|Petrie polygon]] of the 16-cell, and the helical track along which all eight vertices rotate together, in one of the 16-cell's distinct isoclinic [[#Rotations|rotations]].{{Efn|The 16-cell can be constructed from two cell-disjoint eight-cell rings in three different ways; it has three orientations of its pair of rings.

Each eight-cell ring contains three axial octagrams which have different orientations (they exchange roles) in the three discrete fibrations and six distinct isoclinic rotations (three left and three right) through the cell rings. Three octagrams (of different colors) can be seen in the illustration of a single cell ring, one in the role of Petrie polygon, one as the right isocline, and one as the left isocline.

Hence, the 16-cell has a [[W:Dihedral angle|dihedral angle]] of 120°.{{sfn|Coxeter|1973|p=293}} Each 16-cell has 16 neighbors with which it shares a tetrahedron, 24 neighbors with which it shares only an edge, and 72 neighbors with which it shares only a single point. Twenty-four 16-cells meet at any given vertex in this tessellation. The dual tessellation, the [[W:24-cell honeycomb|24-cell honeycomb]], {3,4,3,3}, is made of regular [[24-cell]]s.

(Each cell is drawn with different color faces, inverted cells are undrawn)]] The cell-first parallel projection of the 16-cell into 3-space has a [[W:cube|cubical]] envelope. The closest and farthest cells are projected to inscribed tetrahedra within the cube, corresponding with the two possible ways to inscribe a regular tetrahedron in a cube. Surrounding each of these tetrahedra are 4 other (non-regular) tetrahedral volumes that are the images of the 4 surrounding tetrahedral cells, filling up the space between the inscribed tetrahedron and the cube. The remaining 6 cells are projected onto the square faces of the cube. In this projection of the 16-cell, all its edges lie on the faces of the cubical envelope. The cell-first perspective projection of the 16-cell into 3-space has a [[W:triakis tetrahedron|triakis tetrahedral]] envelope. The layout of the cells within this envelope are analogous to that of the cell-first parallel projection. The vertex-first parallel [[W:Graphical projection|projection]] of the 16-cell into 3-space has an [[W:octahedron|octahedral]] [[W:projection envelope|envelope]]. This octahedron can be divided into 8 tetrahedral volumes, by cutting along the coordinate planes. Each of these volumes is the image of a pair of cells in the 16-cell. The closest vertex of the 16-cell to the viewer projects onto the center of the octahedron. Finally the edge-first parallel projection has a shortened octahedral envelope, and the face-first parallel projection has a [[W:hexagonal bipyramid]]al envelope. == 4 sphere Venn diagram == A 3-dimensional projection of the 16-cell and 4 intersecting spheres (a [[W:Venn diagram|Venn diagram]] of 4 sets) are [[W:topology|topologically]] equivalent. {| |- | {{multiple image | align = left | total_width = 700 | image1 = 4 spheres, cell 00, solid.png | image2 = 4 spheres, weight 1, solid.png | image3 = 4 spheres, weight 2, solid.png | image4 = 4 spheres, weight 3, solid.png | image5 = 4 spheres, cell 15, solid.png | footer = The 16 cells ordered by number of intersecting spheres (from 0 to 4) &nbsp;&nbsp;&nbsp; <small>(see all [[commons:Category:Venn diagrams rgby; single cells|cells]] and [[v:Tesseract and 16-cell faces|''k''-faces]])</small> }} | {{multiple image | align = right | total_width = 290 | image1 = 4 spheres as rings, vertical.png | image2 = Stereographic polytope 16cell.png | footer = 4 sphere Venn diagram and 16-cell projection in the same orientation }} |} == Symmetry constructions == The 16-cell's [[W:Coxeter group|symmetry group]] is denoted [[W:B4 polytope|B<sub>4</sub>]].

The vertex coordinates form 6 [[W:Orthogonal|orthogonal]] central squares lying in the 6 coordinate planes. 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).

We are always on (or in) the ''surface'' of the 16-cell, never inside the 16-cell itself (nor outside it). We can see that the 6 edges around each vertex radiate symmetrically in 3 dimensions and form an orthogonal 3-axis cross, just as the radii of an octahedron do (so we say the vertex figure of the 16-cell is the octahedron).{{Efn|name=octahedral pyramid}}}} It has 32 [[W:Triangle (geometry)|triangular]] [[W:Face (geometry)|faces]], 24 [[W:Edge (geometry)|edges]], and 8 [[W:Vertex (geometry)|vertices]].

In 4 dimensions, the vertex octahedron is actually an octahedral pyramid. The apex of the octahedral pyramid (the vertex where the 6 edges meet) is not actually at the center of the octahedron: it is displaced radially outwards in the fourth dimension, out of the hyperplane defined by the octahedron's 6 vertices. The 6 edges around the vertex make an orthogonal 3-axis cross in 3 dimensions (and in the [[W:Octahedral pyramid|3-dimensional projection of the 4-pyramid]]), but the 3 lines are actually bent 90 degrees in the fourth dimension where they meet in an apex.|name=octahedral pyramid}} The 6 orthogonal central planes of the 16-cell can be divided into 4 orthogonal central hyperplanes (3-spaces) each forming an [[W:Octahedron|octahedron]] with 3 orthogonal great squares. === Rotations === {| class="wikitable" width=480 |- align=center valign=top |rowspan=2|[[File:16-cell.gif]]<br />A 3D projection of a 16-cell performing a [[W:SO(4)#Simple rotations|simple rotation]] |[[File:16-cell-orig.gif]]<br />A 3D projection of a 16-cell performing a [[W:SO(4)#Double rotations|double rotation]] |} [[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 [[w:Completely_orthogonal|completely orthogonal]] planes.{{Sfn|Kim|Rote|2016|p=6|loc=§&nbsp;5.

The two squares cannot intersect at all because they lie in planes which intersect at only one point: the center of the 16-cell.{{Efn|name=Six orthogonal planes of the Cartesian basis}} Because they are perpendicular and share a common center, the two squares are obviously not parallel and separate in the usual way of parallel squares in 3 dimensions; rather they are connected like adjacent square links in a chain, each passing through the other without intersecting at any points, forming a [[W:Hopf link|Hopf link]].|name=Clifford parallel great squares}} In 2 or 3 dimensions a rotation is characterized by a single plane of rotation; this kind of rotation taking place in 4-space is called a [[W:Rotations in 4-dimensional Euclidean space#Simple rotations|simple rotation]], in which only one of the two completely orthogonal planes rotates (the angle of rotation in the other plane is 0). In the 16-cell, a simple rotation in one of the 6 orthogonal planes moves only 4 of the 8 vertices; the other 4 remain fixed. (In the simple rotation animation above, all 8 vertices move because the plane of rotation is not one of the 6 orthogonal basis planes.) In a [[W:Rotations in 4-dimensional Euclidean space#Double rotations|double rotation]] both sets of 4 vertices move, but independently: the angles of rotation may be different in the 2 completely orthogonal planes. If the two angles happen to be the same, a maximally symmetric [[W:Rotations in 4-dimensional Euclidean space#Isoclinic rotations|isoclinic rotation]] takes place.{{Efn|In an isoclinic rotation, all 6 orthogonal planes are displaced in two orthogonal directions at once: they are rotated by the angle, and at the same time they are tilted ''sideways'' by that same angle. An isoclinic displacement (also known as a [[W:William Kingdon Clifford|Clifford]] displacement) is 4-dimensionally diagonal. Points are displaced an equal distance in four orthogonal directions at once, and displaced a total [[W:Pythagorean distance#Higher dimensions|Pythagorean distance]] equal to the square root of four times the square of that distance (which is two times that distance). For example, when the unit-radius 16-cell rotates isoclinically 90° in a great square invariant plane, it also rotates 90° in the completely orthogonal great square invariant plane.{{Efn||name=Six orthogonal planes of the Cartesian basis}} The great square plane tilts sideways 90° to occupy its completely orthogonal plane. (By isoclinic symmetry, ''every'' great square plane rotates 90° ''and'' tilts sideways 90° into its completely orthogonal plane.)

It is a helical 180° arc that bends in a circle in two completely orthogonal planes at once.

If the isoclinic rotation is continued through another 90°, each vertex completes a 360° rotation and each great square returns to its original plane, but in a different orientation (axes swapped): it has been turned "upside down" on the surface of the 16-cell (which is now "inside out"). Continuing through a second 360° isoclinic rotation (through four 90° by 90° isoclinic steps, a 720° rotation) returns everything to its original place and orientation.|name=exchange of completely orthogonal planes}} === Constructions === ==== Octahedral dipyramid ==== {|class="wikitable floatright" !Octahedron <math>\beta_3</math> !16-cell <math>\beta_4</math> |- |[[File:3-cube t2.svg|160px]] |[[File:4-demicube t0 D4.svg|160px]] |- |colspan=2|Orthogonal projections to skew hexagon hyperplane |} The simplest construction of the 16-cell is on the 3-dimensional cross polytope, the [[W:Octahedron|octahedron]].

Each square intersects with each of the other squares at two opposite vertices, with ''two'' of the squares crossing at each vertex. Then two more points are added in the fourth dimension (above and below the 3-dimensional hyperplane).

Notice that each square no longer intersects with ''all'' of the other squares: it does intersect with four of them (with ''three'' of the squares crossing at each vertex now), but each square has ''one'' other square with which it shares ''no'' vertices: it is not directly connected to that square at all. These two ''separate'' perpendicular squares (there are three pairs of them) are like the opposite edges of a [[W:Tetrahedron|tetrahedron]]: perpendicular, but non-intersecting. They lie opposite each other (parallel in some sense), and they don't touch, but they also pass through each other like two perpendicular links in a chain (but unlike links in a chain they have a common center).

The [[W:Petrie polygon|Petrie polygon]] of the 16-cell is a skew octagon, visible as the purple edges in the octagon orthogonal projection, and as the light blue edges in the tetrahedral helix. Each eight-cell ring of tetrahedra actually contains three such skew [[W:Octagram|octagram]]s of different colors, eight-edge circular paths that wind twice around the 16-cell on every third vertex of the octagram. The orange and yellow edges are two four-edge halves of one skew octagram, which join their ends to form a [[W:Möbius strip|Möbius strip]]. Thus the 16-cell can be decomposed into two cell-disjoint circular chains of eight tetrahedrons each, four edges long, one spiraling to the right (clockwise) and the other spiraling to the left (counterclockwise). The left-handed and right-handed cell rings fit together, nesting into each other and entirely filling the 16-cell, even though they are of opposite chirality. This decomposition can be seen in a 4-4 [[W:Duoantiprism|duoantiprism]] construction of the 16-cell: {{Coxeter–Dynkin diagram|node_h|2x|node_h|2x|node_h|2x|node_h}} or {{Coxeter–Dynkin diagram|node|4|node_h|2x|node_h|4|node}}, [[W:Schläfli symbol|Schläfli symbol]] {2}⨂{2} or s{2}s{2}, [[W:Coxeter notation|symmetry]] [4,2<sup>+</sup>,4], order 64. Three eight-edge paths (of different colors) spiral along each eight-cell ring, making 90° angles at each vertex. (In the Boerdijk–Coxeter helix before it is bent into a ring, the angles in different paths vary, but are not 90°.) Three paths (with three different colors and apparent angles) pass through each vertex. When the helix is bent into a ring, the segments of each eight-edge path (of various lengths) join their ends, forming a Möbius strip eight edges long along its single-sided circumference of 4𝝅, and one edge wide.{{Efn|name=Möbius circle}} The six four-edge halves of the three eight-edge paths each make four 90° angles, but they are ''not'' the six orthogonal great squares: they are open-ended squares, four-edge 360° helices whose open ends are [[W:Antipodal point|antipodal]] vertices. The four edges come from four different great squares, and are mutually orthogonal. Combined end-to-end in pairs of the same [[W:Chirality|chirality]], the six four-edge paths make three eight-edge Möbius loops, [[W:Helix|helical]] octagrams.

There is also another way in which completely orthogonal planes are in a distinguished category of Clifford parallel planes: they are not [[W:Chiral|chiral]]. A pair of isoclinic (Clifford parallel) planes is either a ''left pair'' or a ''right pair'' unless they are separated by two angles of 90° (completely orthogonal planes) or 0° (coincident planes).{{Sfn|Kim|Rote|2016|pp=7-8|loc=§&nbsp;6 Angles between two Planes in 4-Space|ps=; Left and Right Pairs of Isoclinic Planes.}} Most isoclinic planes are brought together only by a left isoclinic rotation or a right isoclinic rotation, respectively. Completely orthogonal planes are special: the pair of planes is both a left and a right pair, so either a left or a right isoclinic rotation will bring them together. Because planes separated by a 90° isoclinic rotation are 180° apart, the plane to the ''left'' and the plane to the ''right'' are the same plane.{{Efn|name=exchange of completely orthogonal planes}}|name=completely orthogonal Clifford parallels are special}} To see ''how'' and ''why'' they are special, visualize two completely orthogonal invariant planes of rotation, each rotating by some rotation angle ''and'' tilting sideways by the same rotation angle into a different plane entirely.{{Efn|name=isoclinic rotation}} ''Only when the rotation angle is 90°,'' that different plane in which the tilting invariant plane lands will be the completely orthogonal invariant plane itself. The destination plane of the rotation ''is'' the completely orthogonal invariant plane. The 90° isoclinic rotation is the only rotation which takes the completely orthogonal invariant planes to each other.{{Efn|name=exchange of completely orthogonal planes}} This reciprocity is the reason both left and right rotations go to the same place.}} === As a configuration === This [[W:Regular 4-polytope#As configurations|configuration matrix]] represents the 16-cell.

The closest and farthest cells are projected to inscribed tetrahedra within the cube, corresponding with the two possible ways to inscribe a regular tetrahedron in a cube. Surrounding each of these tetrahedra are 4 other (non-regular) tetrahedral volumes that are the images of the 4 surrounding tetrahedral cells, filling up the space between the inscribed tetrahedron and the cube. The remaining 6 cells are projected onto the square faces of the cube. In this projection of the 16-cell, all its edges lie on the faces of the cubical envelope. The cell-first perspective projection of the 16-cell into 3-space has a [[W:triakis tetrahedron|triakis tetrahedral]] envelope. The layout of the cells within this envelope are analogous to that of the cell-first parallel projection. The vertex-first parallel [[W:Graphical projection|projection]] of the 16-cell into 3-space has an [[W:octahedron|octahedral]] [[W:projection envelope|envelope]].

Three paths (with three different colors and apparent angles) pass through each vertex.

The 16-cell contains three left-right pairs of eight-cell rings in different orientations, with each cell ring containing its axial isocline.{{Efn|name=only one disjoint pair of eight-cell rings}} Each left-right pair of isoclines is the track of a left-right pair of distinct isoclinic rotations: the rotations in one pair of completely orthogonal invariant planes of rotation.{{Efn|name=Clifford parallel great squares}} At each vertex, there are three great squares and six octagram isoclines that cross at the vertex and share a 16-cell axis chord.{{Efn|This is atypical for isoclinic rotations generally; normally both the left and right isoclines do not occur at the same vertex: there are two disjoint sets of vertices reachable only by the left or right rotation respectively.{{Efn|name=counter-rotating double helix}} The left and right isoclines of the 16-cell form a very special double helix: unusual not just because it is circular, but because its different left and right helices twist around each other through the ''same set'' of antipodal vertices,{{Efn|name=each 16-cell isocline reaches all 8 vertices}} not through the two ''disjoint subsets'' of antipodal vertices, as the isocline pairs do in most isoclinic rotations found in nature.{{Efn|For another example of the left and right isoclines of a rotation visiting the same set of vertices, see the [[5-cell#Geodesics and rotations|characteristic isoclinic rotation of the 5-cell]]. Although in these two special cases left and right isoclines of the same rotation visit the same set of vertices, they still take very different rotational paths because they visit the same vertices in different sequences.|name=two special cases}} Isoclinic rotations in completely orthogonal invariant planes are special.{{Efn|Each great square plane is isoclinic (Clifford parallel) to five other square planes but completely orthogonal to only one of them. Every pair of completely orthogonal planes has Clifford parallel great circles, but not all Clifford parallel great circles are orthogonal. There is also another way in which completely orthogonal planes are in a distinguished category of Clifford parallel planes: they are not [[W:Chiral|chiral]]. A pair of isoclinic (Clifford parallel) planes is either a ''left pair'' or a ''right pair'' unless they are separated by two angles of 90° (completely orthogonal planes) or 0° (coincident planes).{{Sfn|Kim|Rote|2016|pp=7-8|loc=§&nbsp;6 Angles between two Planes in 4-Space|ps=; Left and Right Pairs of Isoclinic Planes.}} Most isoclinic planes are brought together only by a left isoclinic rotation or a right isoclinic rotation, respectively. Completely orthogonal planes are special: the pair of planes is both a left and a right pair, so either a left or a right isoclinic rotation will bring them together. Because planes separated by a 90° isoclinic rotation are 180° apart, the plane to the ''left'' and the plane to the ''right'' are the same plane.{{Efn|name=exchange of completely orthogonal planes}}|name=completely orthogonal Clifford parallels are special}} To see ''how'' and ''why'' they are special, visualize two completely orthogonal invariant planes of rotation, each rotating by some rotation angle ''and'' tilting sideways by the same rotation angle into a different plane entirely.{{Efn|name=isoclinic rotation}} ''Only when the rotation angle is 90°,'' that different plane in which the tilting invariant plane lands will be the completely orthogonal invariant plane itself. The destination plane of the rotation ''is'' the completely orthogonal invariant plane. The 90° isoclinic rotation is the only rotation which takes the completely orthogonal invariant planes to each other.{{Efn|name=exchange of completely orthogonal planes}} This reciprocity is the reason both left and right rotations go to the same place.}} === As a configuration === This [[W:Regular 4-polytope#As configurations|configuration matrix]] represents the 16-cell.

The closest and farthest cells are projected to inscribed tetrahedra within the cube, corresponding with the two possible ways to inscribe a regular tetrahedron in a cube. Surrounding each of these tetrahedra are 4 other (non-regular) tetrahedral volumes that are the images of the 4 surrounding tetrahedral cells, filling up the space between the inscribed tetrahedron and the cube. The remaining 6 cells are projected onto the square faces of the cube. In this projection of the 16-cell, all its edges lie on the faces of the cubical envelope. The cell-first perspective projection of the 16-cell into 3-space has a [[W:triakis tetrahedron|triakis tetrahedral]] envelope. The layout of the cells within this envelope are analogous to that of the cell-first parallel projection. The vertex-first parallel [[W:Graphical projection|projection]] of the 16-cell into 3-space has an [[W:octahedron|octahedral]] [[W:projection envelope|envelope]]. This octahedron can be divided into 8 tetrahedral volumes, by cutting along the coordinate planes. Each of these volumes is the image of a pair of cells in the 16-cell. The closest vertex of the 16-cell to the viewer projects onto the center of the octahedron.

The vertex coordinates form 6 [[W:Orthogonal|orthogonal]] central squares lying in the 6 coordinate planes.

In the 16-cell, a simple rotation in one of the 6 orthogonal planes moves only 4 of the 8 vertices; the other 4 remain fixed. (In the simple rotation animation above, all 8 vertices move because the plane of rotation is not one of the 6 orthogonal basis planes.) In a [[W:Rotations in 4-dimensional Euclidean space#Double rotations|double rotation]] both sets of 4 vertices move, but independently: the angles of rotation may be different in the 2 completely orthogonal planes. If the two angles happen to be the same, a maximally symmetric [[W:Rotations in 4-dimensional Euclidean space#Isoclinic rotations|isoclinic rotation]] takes place.{{Efn|In an isoclinic rotation, all 6 orthogonal planes are displaced in two orthogonal directions at once: they are rotated by the angle, and at the same time they are tilted ''sideways'' by that same angle.

Points are displaced an equal distance in four orthogonal directions at once, and displaced a total [[W:Pythagorean distance#Higher dimensions|Pythagorean distance]] equal to the square root of four times the square of that distance (which is two times that distance). For example, when the unit-radius 16-cell rotates isoclinically 90° in a great square invariant plane, it also rotates 90° in the completely orthogonal great square invariant plane.{{Efn||name=Six orthogonal planes of the Cartesian basis}} The great square plane tilts sideways 90° to occupy its completely orthogonal plane. (By isoclinic symmetry, ''every'' great square plane rotates 90° ''and'' tilts sideways 90° into its completely orthogonal plane.) Each vertex (in every great square) is displaced to its antipodal vertex, at a distance of {{radic|1}} in each of four orthogonal directions, a total distance of {{radic|4}}. The original and displaced vertex are two edge lengths apart by three{{Efn|There are six different two-edge paths connecting a pair of antipodal vertices along the edges of a great square.

If the isoclinic rotation is continued through another 90°, each vertex completes a 360° rotation and each great square returns to its original plane, but in a different orientation (axes swapped): it has been turned "upside down" on the surface of the 16-cell (which is now "inside out").

It contains an ''isocline'' axis (not shown), a helical circle of circumference 4𝝅 that twists through all four dimensions and visits all 8 vertices.{{Efn|name=isocline}} The two blue-blue-yellow triangles at either end of the cut ring are the same object.]] [[File:16-cell 8-ring net4.png|thumb|Net and orthogonal projection]] A 16-cell can be constructed (three different ways) from two [[W:Boerdijk–Coxeter helix|Boerdijk–Coxeter helix]]es of eight chained tetrahedra, each bent in the fourth dimension into a ring.{{Sfn|Coxeter|1970|loc=Table 2: Reflexible honeycombs and their groups|p=45|ps=; Honeycomb [3,3,4]<sub>4</sub> is a tiling of the 3-sphere by 2 rings of 8 tetrahedral cells.}}{{Sfn|Banchoff|2013}} The two circular helixes share the same 8 vertices and 24 edges, but their tetrahedra are disjoint. The helixes spiral around each other, nest into each other and pass through each other forming a [[W:Hopf link|Hopf link]]. 16 of the 32 triangle faces can be seen in a 2D net within a [[W:Triangular tiling|triangular tiling]], with 6 triangles around every vertex. The [[W:Petrie polygon|Petrie polygon]] of the 16-cell is a skew octagon, visible as the purple edges in the octagon orthogonal projection, and as the light blue edges in the tetrahedral helix. Each eight-cell ring of tetrahedra actually contains three such skew [[W:Octagram|octagram]]s of different colors, eight-edge circular paths that wind twice around the 16-cell on every third vertex of the octagram. The orange and yellow edges are two four-edge halves of one skew octagram, which join their ends to form a [[W:Möbius strip|Möbius strip]]. Thus the 16-cell can be decomposed into two cell-disjoint circular chains of eight tetrahedrons each, four edges long, one spiraling to the right (clockwise) and the other spiraling to the left (counterclockwise). The left-handed and right-handed cell rings fit together, nesting into each other and entirely filling the 16-cell, even though they are of opposite chirality. This decomposition can be seen in a 4-4 [[W:Duoantiprism|duoantiprism]] construction of the 16-cell: {{Coxeter–Dynkin diagram|node_h|2x|node_h|2x|node_h|2x|node_h}} or {{Coxeter–Dynkin diagram|node|4|node_h|2x|node_h|4|node}}, [[W:Schläfli symbol|Schläfli symbol]] {2}⨂{2} or s{2}s{2}, [[W:Coxeter notation|symmetry]] [4,2<sup>+</sup>,4], order 64. Three eight-edge paths (of different colors) spiral along each eight-cell ring, making 90° angles at each vertex. (In the Boerdijk–Coxeter helix before it is bent into a ring, the angles in different paths vary, but are not 90°.) Three paths (with three different colors and apparent angles) pass through each vertex. When the helix is bent into a ring, the segments of each eight-edge path (of various lengths) join their ends, forming a Möbius strip eight edges long along its single-sided circumference of 4𝝅, and one edge wide.{{Efn|name=Möbius circle}} The six four-edge halves of the three eight-edge paths each make four 90° angles, but they are ''not'' the six orthogonal great squares: they are open-ended squares, four-edge 360° helices whose open ends are [[W:Antipodal point|antipodal]] vertices. The four edges come from four different great squares, and are mutually orthogonal. Combined end-to-end in pairs of the same [[W:Chirality|chirality]], the six four-edge paths make three eight-edge Möbius loops, [[W:Helix|helical]] octagrams. Each octagram is both a [[W:Petrie polygon|Petrie polygon]] of the 16-cell, and the helical track along which all eight vertices rotate together, in one of the 16-cell's distinct isoclinic [[#Rotations|rotations]].{{Efn|The 16-cell can be constructed from two cell-disjoint eight-cell rings in three different ways; it has three orientations of its pair of rings. Each orientation "contains" a distinct left-right pair of isoclinic rotations, and also a pair of completely orthogonal great squares (Clifford parallel fibers), so each orientation is a discrete [[W:Hopf fibration|fibration]] of the 16-cell. Each eight-cell ring contains three axial octagrams which have different orientations (they exchange roles) in the three discrete fibrations and six distinct isoclinic rotations (three left and three right) through the cell rings. Three octagrams (of different colors) can be seen in the illustration of a single cell ring, one in the role of Petrie polygon, one as the right isocline, and one as the left isocline.

People using their phone on the train.]] '''Imagine this ...''' You are sitting on a crowded train after a long day. A young boy nearby laughs at a meme on Instagram. A woman beside him scrolls through her messages. Across the aisle, a student types reminders into a calendar app. Next to you, a man endlessly scrolls through social media updates. What draws each of these people to their phone? Is it comfort, connection, distraction, or control? These are everyday actions, yet behind them lie hidden motivations that shape our relationship with smartphones. {{RoundBoxBottom}} [[wikipedia:Mobile_phone|Mobile phones]] are central to modern life, influencing how people work, connect, and cope with [[wikipedia:Stress_(biology)|stress]]. Their use is driven by complex psychological needs that affect daily [[wikipedia:Behavior|behaviour]] and [[wikipedia:Well-being|wellbeing]]. Understanding these [[wikipedia:Motivation|motivations]] reveals why people engage with phones in unique ways, and why these behaviours can bring both benefits and challenges. [[wikipedia:Smartphone|Smartphones]] enhance productivity, entertainment, and social bonds. Yet, excessive or compulsive use can lead to [[wikipedia:Procrastination|procrastination]], [[wikipedia:Anxiety|anxiety]], and emotional [[wikipedia:Avoidance_coping|avoidance]]. This chapter explores how motivations shape phone use and offers strategies for healthier, intentional smartphone use that supports wellbeing. {{RoundBoxTop|theme=3}} '''Focus questions''' * What motivates people to use smartphones in their daily lives? * What psychological theories explain these motivations? * How do different motivations impact wellbeing in positive and negative ways? * What strategies can encourage mindful and beneficial phone use? {{RoundBoxBottom}} == Key motivations for mobile phone use == People use mobile phones to satisfy different psychological needs. These needs are typically categorised as instrumental (task-focused), hedonic (pleasure-oriented), social (connection-based), and emotional (coping-related) (Sundar & Limperos, 2013). These motivations explain how phones are integrated into daily life and how they influence wellbeing (Davis, 1989). == Instrumental and pragmatic motivations == {{RoundBoxTop|theme=1}}[[File:Boy from vector.svg|30px|link=]] '''Case example: Alex''' Alex starts each morning by checking the weather app, navigating traffic with GPS, reviewing lecture notes, and setting assignments reminders. Each action is purposeful and task-oriented. His smartphone works as a practical assistant, helping him manage academic and daily tasks. {{RoundBoxBottom}} Instrumental motivations describe using phones to achieve specific goals. These motivations support productivity, scheduling, navigation, and information access (Joo & Sang, 2013). Pragmatic motivations are a subtype of instrumental motivations, focusing on immediate benefits such as reassurance during emergencies or quick information access (Meng et al., 2020). Together, these motivations position smartphones as essential tools for managing everyday life (Wilson et al., 2022). [[File:Online calendar used for scheduling.png|thumb|''Figure 2.'' An example of an online calendar used daily to organise and schedule tasks.|300x300px]]'''Theoretical explanation''' Two psychological models explain these motivations. *The [[wikipedia:Technology_acceptance_model|technology acceptance model]] (TAM): TAM proposes that technology use depends on perceived usefulness and ease of use (Davis, 1989). When phones are both effective and effortless, they are more likely to be integrated into daily routines. This aligns with the [[wikipedia:Theory_of_reasoned_action|theory of reasoned action]], which views attitudes as strong predictors of behaviour (Fishbein & Ajzen, 1975). *The [[wikipedia:Uses_and_gratifications_theory|uses and gratifications theory]] (UGT): UGT views smartphone users as active decision-makers who adopt media to fulfil personal needs (Katz et al., 1973). Instrumental use reflects utility-based gratifications, such as finding directions, setting reminders, or contacting help (Park et al., 2009). These models show how technology design and user choice shape instrumental motivation. '''Research evidence''' Instrumental phone use is consistently linked to positive outcomes. Purposeful engagement such as accessing information, improving productivity, and navigating with GPS supports daily functioning (Wilson et al., 2022). For older adults, instrumental use helps coordinate activities and supports both cognitive and social functioning (Wilson et al., 2022). Pragmatic motivations extend these benefits by providing reassurance and safety, especially during emergencies (Meng et al., 2020). From TAM's perspective, these outcomes illustrate how perceived usefulness encourages routine phone behaviour (Davis, 1989). Meng et al. (2020) found that instrumental use is less likely to lead to dependency compared to hedonic or emotional motivations. This suggests instrumental use promotes a balanced engagement with smartphones. However, risks exist. An over-reliance on GPS may impair spatial awareness (Ruginski et al., 2019), and habitual checking of reminders can weaken memory and problem-solving skills (Elhai et al., 2017). UGT helps explain this shift from adaptive to maladaptive outcomes. While users initially select tools for convenience, {{g]} however reliance can turn into habit, diminishing autonomy and flexibility (Kardefelt-Winther, 2014). '''Summary''' Instrumental and pragmatic motivations generally support adaptive outcomes. Phones act as practical assistants, helping people stay organised, informed, and safe. TAM and UGT show that when phones are useful and easy to use, they integrate smoothly into daily life. Yet, the same convenience may reduce independence if it replaces critical skills. These motivations are most beneficial when phones complement rather than replace human capabilities (Joo & Sang, 2013). == Hedonic and entertainment motivations == {{RoundBoxTop|theme=2}}[[File:Girl silhouette.svg|20px|link=]] '''Case example: Sarah''' After a long day of studying, Sarah relaxes by watching videos on TikTok or playing mobile games like Clash of Clans. These activities improve her mood and distract her from her current stress. But sometimes these activities delay her sleep and cut into her study time. {{RoundBoxBottom}} Hedonic motivations describe using phones for enjoyment, escape, and relief from boredom. This includes watching videos, gaming, scrolling [[wikipedia:Social_media|social media]], or listening to music. These activities provide quick pleasure and immersion (Granic et al., 2014). '''Theoretical explanation''' Three psychological perspectives explain how hedonic motivations drive mobile phone use. *The uses and gratifications theory: People actively select media to meet needs such as entertainment, diversion, and relaxation (Katz et al., 1973). Smartphones amplify these gratifications because they combine many entertainment functions in one portable device (Sundar & Limperos, 2013). *[[wikipedia:Self-determination_theory|Self-determination theory (SDT)]]: Hedonic use can satisfy the basic psychological needs for autonomy and competence, enhancing intrinsic motivation (Deci & Ryan, 1985) For example, choosing a playlist supports autonomy. Beating a level in a game provides competence. Sharing a video with friends strengthens relatedness. When these needs are met, hedonic use can enhance wellbeing (Jeno et al., 2017). *The compensatory internet use theory (CIUT): People use online entertainment to cope with stress, loneliness, or unmet needs (Kardefelt-Winther, 2014). For students like Sarah, this may mean escaping academic pressure through binge-watching or gaming. While this coping strategy may provide temporary relief, it can also become maladaptive if it replaces healthier habits like rest or social interaction (Elhai et al., 2019). Together, these theories show that hedonic use is about mood regulation, need fulfilment, and distraction.[[File:Young boy watching a video on his phone.png|thumb|''Figure 3.'' A person enjoying watching a video on their phone.]] '''Research evidence''' Short bursts of gaming or video watching can reduce stress and help recovery from daily strain (Reinecke & Eden, 2016). Adolescents who engage in these activities with peers also report stronger friendships and an increased sense of belonging (Granic et al., 2014). From the perspective of self-determination theory, these hedonic activities satisfy psychological needs for competence and relatedness, supporting wellbeing when used in moderation (Deci & Ryan, 2000). However, risks arise when hedonic use becomes excessive. A meta-analysis by Kuss et al. (2018) found a moderate association between hedonic phone use and poorer sleep quality. This corroborates findings from national survey data. For instance, 70% of Australian teenagers use their phones in bed, with half of them reporting shorter sleep durations (Sleep Health Foundation, 2022). The compensatory internet use theory helps explain this pattern. While entertainment can offer short-term stress relief, excessive reliance may reinforce avoidance coping, negatively affecting wellbeing over time (Elhai et al., 2017). The uses and gratifications theory further clarifies these risks by showing how entertainment use can shift from intentional choice to automatic checking. This diminishes autonomy and reinforces distraction habits (Sundar & Limperos, 2013). Similarly, the self-determination theory suggests that hedonic use dominated by stress or obligation fails to satisfy basic needs and may undermine health (Deci & Ryan, 1985). '''Summary''' Hedonic motivations highlights the double-edged nature of mobile entertainment. When balanced, these activities fulfil psychological needs and aid recovery from stress (Reinecke & Eden, 2016). Conversely, when driven by avoidance or habit, they can impair sleep, learning, and overall wellbeing (Kuss et al., 2018). The impact depends less on the technology itself and more on whether people use it as a balanced form of enjoyment or as a substitute for healthier coping strategies. {{RoundBoxTop|theme=9}} [[File:Thought_bubble.svg|40px|link=]] '''Reflection box: How do you use your phone for entertainment?''' Think about the last time you used your phone just for enjoyment (e.g., watching videos, playing games, scrolling social media). *Did it help you feel more relaxed or energised? *Did it ever interfere with your sleep? *What needs (autonomy, competence, connection) do you think were met by that phone use? {{RoundBoxBottom}} == Social motivations == {{RoundBoxTop|theme=3}} [[File:Girl silhouette.svg|20px|link=]] '''Case example: Taylor''' Taylor recently moved to a new city for university. She uses messaging apps, video calls, and social media to stay in touch with old friends. These interactions help her feel connected to her community, despite the distance. {{RoundBoxBottom}} Taylor’s behaviour reflects social motivations. These motivations stem from the human need for connection, belonging, and validation. Phones allow people to maintain relationships, share updates and feel included regardless of distance. Social motivations include messaging, posting content, and joining online groups. While often rewarding, social use can also create pressure to stay available and can increase stress when users feel excluded (Kim & Lee, 2011). '''Theoretical explanation''' Three psychological models explain how social motivations drive mobile phone use. *Self-determination theory: SDT identifies relatedness as a basic psychological need, alongside autonomy and competence (Deci & Ryan, 2000). Phones support relatedness by offering frequent contact (Joo & Sang, 2013). However, when connections are pursued out of obligation or fear of exclusion, the benefits of relatedness decline (Kushlev et al., 2016). *Uses and gratifications theory: UGT sees users as active decision-makers who choose media that fulfils needs such as belonging, reassurance, or identity expression (Katz et al., 1973). Phones make this easy by providing instant connection. *Compensatory Internet Use Theory (CIUT): CIUT proposes that people use online communication to compensate for offline social challenges (Kardefelt-Winther, 2014). For example, students may rely on group chats or social media to reduce loneliness or social anxiety. While this can provide temporary comfort, it may also reinforce dependence and reduce engagement in offline interactions. Together, these perspectives suggest that social motivations can be both supportive and anxiety-driven. '''Research evidence''' Research highlights both benefits and risks associated with social phone use. On the positive side, social interactions via smartphones strengthen perceived support and bonding. Tools like messaging, [[wikipedia:Videotelephony|video calls]], and [[wikipedia:Chat_room|group chats]] help reduce loneliness and help students adapt to new environments (Joo & Sang, 2013). Surveys show that sharing humour, updates, and encouragement online is linked with higher wellbeing and a stronger sense of belonging (Mission Australia, 2022). These benefits are strongest when social media use is intentional. Sundar and Limperos (2013) found that focusing on meaningful exchanges rather than constant scrolling reduces loneliness and supports resilience. From the perspective of SDT, this shows how social needs for relatedness can be fulfilled in autonomy-supportive ways (Deci & Ryan, 2000). [[File:Wiki-mascots video call.png|thumb|''Figure 4''. A group of friends using video calls to socialise with each other.|left|330x330px]] However, risks arise when social use is excessive or driven by anxiety. [[wikipedia:Fear_of_missing_out|FoMo]] is strongly linked to compulsive checking, increased stress, and sleep disturbances (Przybylski et al., 2013). Longitudinal studies show that students who mainly use phones to alleviate social anxiety report heightened distress over time (Elhai et al., 2017). This aligns with the CIUT, which suggests that digital connection can serve as avoidance coping. It offers temporary relief but reinforces dependence (Kardefelt-Winther, 2014). UGT further explains that repeated reliance on phones for reassurance fosters habitual checking rather than active coping, increasing vulnerability to problematic use (Kuss et al., 2018). '''Summary''' Social motivations demonstrate how phones serve as tools for belonging. When use is selective and autonomy-supportive, phones enhance wellbeing by fulfilling relatedness needs (Deci & Ryan, 2000). Conversely, when driven by FoMo or avoidance, social phone use may foster stress, dependence, and reduced offline interaction (Elhai et al., 2019). A positive balance depends on whether social phone use supports authentic connection or substitutes for healthier coping strategies. == Emotional and mood regulatory motivations == {{RoundBoxTop|theme=4}} [[File:Boy from vector.svg|30px|link=]] '''Case example: Sam''' Sam often feels anxious before giving class presentations. To cope, he checks his phone for supportive messages and scrolls through Instagram to distract himself. This brings temporary relief but prevents him from addressing the root of his anxiety. {{RoundBoxBottom}} Sam’s behaviour reflects emotional and mood regulatory motivations, where phones are used to manage stress, loneliness, anxiety, sadness, or boredom. Smartphones provide immediate outlets for distraction, reassurance, or self-expression. This helps stabilise mood in the short term. These motivations stem from the basic psychological drive to regulate emotions and regain a sense of control. However, reliance on phones can shift from adaptive coping to maladaptive dependence when overused. '''Theoretical explanation''' Three psychological models explain these dynamics. *[[wikipedia:Emotional_self-regulation|Emotion regulation]] theory: Gross (1998) distinguishes strategies such as distraction, reappraisal, and suppression. Phones support distraction (e.g., scrolling feeds) and can encourage reappraisal by offering uplifting or humorous content. *[[wikipedia:Mood_management_theory|Mood management theory]]: Zillmann (1988) suggests people choose media to reduce negative states or maintain positive ones. Smartphones provide instant access to entertainment, games, and social contact, making them powerful tools for mood adjustment. *Compensatory internet use theory: Kardefelt-Winther (2014) proposes that individuals turn to media to offset offline stressors. While this can relieve tension, it may also fuel avoidance if deeper problems remain unresolved. Together, these theories explain why emotionally motivated phone use can bring short-term relief but also carry long-term risks. '''Research evidence''' Moderate use of relaxation apps, mindfulness tools, or supportive messaging can reduce stress and improve wellbeing in the short term (Reinecke & Eden, 2016). Social sharing and online self-expression offer [[wikipedia:Catharsis|catharsis]] and strengthen social bonds, consistent with mood management theory (Kim & Lee, 2011). Additional evidence shows that reappraisal through positive online content may enhance emotional resilience (Park & Valenzuela, 2009). However, risks arise when emotional regulation relies too heavily on smartphones. Escaping stress through constant phone use has been linked to procrastination, avoidance, and increased stress (Elhai et al., 2019). Heavy nighttime use is consistently linked with poor sleep quality and heightened anxiety (Sleep Health Foundation, 2022). Longitudinal studies further show that depending on phones as a primary coping mechanism predicts worsening depressive symptoms over time, especially in adolescents (Kuss et al., 2018). These findings illustrate the shift from adaptive distraction to maladaptive dependence when stressors remain unaddressed. [[File:Young boy struggling to sleep.png|thumb|''Figure 5.'' Illustration of a young boy struggling to fall asleep at night because he is using his phone before bed.]]'''Summary''' Emotion regulation theory highlights how phones provide quick access to distraction and reappraisal. Mood management theory explains why people seek uplifting or entertaining content. Compensatory internet use theory clarifies why these strategies sometimes slip into avoidance and dependency. Using digital tools is most beneficial when they complement healthy offline coping strategies such as problem-solving, rest, and social support, rather than replacing them (Kushlev et al., 2016). == Practical implications == To promote healthier smartphone use, strategies must address the different motivations that drive behaviour. Grounding these strategies in psychological theory ensures that they move beyond surface-level advice and instead build lasting skills for wellbeing. By tailoring strategies, smartphone use can shift from automatic or avoidant behaviours to intentional habits that enhance autonomy, competence, and relatedness (Deci & Ryan, 2000). '''Instrumental use''' Smartphones are valuable tools for organisation, navigation, and learning. Using calendar apps, focus timers, and note-taking platforms can strengthen autonomy and competence (Deci & Ryan, 2000). Practical strategies could include driving offline routes to maintain spatial awareness while reducing an over-reliance on devices like GPS (Ruginski et al., 2019). Also, reflecting on which apps genuinely support goals helps build self-regulation (Hadlington, 2015). Workplaces, schools, and families can also encourage digital literacy training to help people use apps more intentionally, aligning with self-regulation theory, which emphasises feedback and planning in achieving goals. '''Hedonic use''' Phones provide entertainment and while these activities can improve mood, excessive use can disrupt sleep and concentration (Exelmans & Van den Bulck, 2016). Practical strategies include setting app timers, scheduling intentional leisure breaks, and prioritising stimulating media over passive media (Sundar & Limperos, 2013). Choosing creativity-focused or interactive content enhances wellbeing. Also reducing device use before sleep supports circadian rhythms and reduces fatigue (Exelmans & Van den Bulck, 2016). From the perspective of mood management theory (Zillmann, 1988), these strategies work by channelling hedonic needs into intentional rather than automatic behaviours. This allows people to enjoy pleasure while minimising costs to health and productivity. '''Social use''' Connection with others is a central reason for phone use. Structured strategies, such as curated group chats, online communities, or family check-ins, allow people to maintain relationships without constant checking. Intentional social use through prioritising direct communication over passive scrolling strengthens bonds and wellbeing (Beyens et al., 2020). Reducing notifications or batching social media checks can lower compulsive behaviours (Przybylski et al., 2013). Reflecting on whether engagement arises from genuine interest or obligation helps protect autonomy in relationships (Kushlev et al., 2016). Compensatory Internet Use Theory (Kardefelt-Winther, 2014) suggests that many turn to digital connection to offset stress or loneliness. Pairing online interactions with offline opportunities for belonging, such as community groups or shared hobbies, can reduce dependence while still supporting relatedness. [[File:A young girl listening to music on her phone.png|thumb|''Figure 6.'' An illustration of a young girl listening to music on her mobile phone.]] '''Emotional use''' Smartphones are often used to cope with stress, sadness, or boredom. Adaptive strategies include guided relaxation apps, calming audio, or mood-tracking tools, which can reduce stress in the short term (Reinecke & Eden, 2016). However, coping is most effective when digital tools are paired with offline support such as rest, social support, or problem-solving (Gross, 1998). Reflective practices such as asking “Is this helping me cope, or am I avoiding?” can prevent avoidance cycles linked with poor sleep and heightened anxiety (Elhai et al., 2017). Mood management theory (Zillmann, 1988) {{ic|Not in References}} explains why uplifting content helps regulate emotions. While compensatory internet use theory highlights the risks of relying on avoidance strategies without addressing underlying stressors. ==Conclusion== Smartphone use is driven by instrumental, hedonic, social, and emotional motivations, reflecting basic psychological needs. Psychological theories like TAM, SDT, and UGT show that phones are not inherently good or bad. Their impact depends on the motivations guiding engagement. Smartphones can support productivity, enjoyment, connection, and stress relief, but the same patterns may also foster avoidance, dependency, and reduced wellbeing. This dual role highlights the importance of intentional use. Hedonic use is most rewarding when balanced, and social connection most beneficial when authentic. Instrumental and emotional use require reflection to avoid over-reliance. Recognising personal motivations helps individuals use smartphones as tools for growth, protecting autonomy, rest, and wellbeing. By understanding these dynamics, people can shape technology into an ally for resilience rather than a source of distraction. ==See also== * [[Motivation and emotion/Book/2021/Boredom and technology addiction|Boredom and technology addiction]] (Book chapter, 2021) * [[Motivation and emotion/Book/2016/Mobile phone addiction|Mobile phone addiction]] (Book chapter, 2016) * [[Motivation and emotion/Book/2017/Mobile phone addiction|Mobile phone addiction]] (Book chapter, 2017) * [[Motivation and emotion/Book/2023/Mobile phone use motivation|Mobile phone use motivation]] (Book chapter, 2023) ==References== {{Hanging indent|1= Beyens, I., Pouwels, J.

People using their phone on the train.]] '''Imagine this ...''' You are sitting on a crowded train after a long day. A young boy nearby laughs at a meme on Instagram. A woman beside him scrolls through her messages. Across the aisle, a student types reminders into a calendar app. Next to you, a man endlessly scrolls through social media updates. What draws each of these people to their phone? Is it comfort, connection, distraction, or control? These are everyday actions, yet behind them lie hidden motivations that shape our relationship with smartphones. {{RoundBoxBottom}} [[wikipedia:Mobile_phone|Mobile phones]] are central to modern life, influencing how people work, connect, and cope with [[wikipedia:Stress_(biology)|stress]]. Their use is driven by complex psychological needs that affect daily [[wikipedia:Behavior|behaviour]] and [[wikipedia:Well-being|wellbeing]]. Understanding these [[wikipedia:Motivation|motivations]] reveals why people engage with phones in unique ways, and why these behaviours can bring both benefits and challenges. [[wikipedia:Smartphone|Smartphones]] enhance productivity, entertainment, and social bonds. Yet, excessive or compulsive use can lead to [[wikipedia:Procrastination|procrastination]], [[wikipedia:Anxiety|anxiety]], and emotional [[wikipedia:Avoidance_coping|avoidance]]. This chapter explores how motivations shape phone use and offers strategies for healthier, intentional smartphone use that supports wellbeing. {{RoundBoxTop|theme=3}} '''Focus questions''' * What motivates people to use smartphones in their daily lives? * What psychological theories explain these motivations? * How do different motivations impact wellbeing in positive and negative ways? * What strategies can encourage mindful and beneficial phone use? {{RoundBoxBottom}} == Key motivations for mobile phone use == People use mobile phones to satisfy different psychological needs. These needs are typically categorised as instrumental (task-focused), hedonic (pleasure-oriented), social (connection-based), and emotional (coping-related) (Sundar & Limperos, 2013). These motivations explain how phones are integrated into daily life and how they influence wellbeing (Davis, 1989). == Instrumental and pragmatic motivations == {{RoundBoxTop|theme=1}}[[File:Boy from vector.svg|30px|link=]] '''Case example: Alex''' Alex starts each morning by checking the weather app, navigating traffic with GPS, reviewing lecture notes, and setting assignments reminders. Each action is purposeful and task-oriented. His smartphone works as a practical assistant, helping him manage academic and daily tasks. {{RoundBoxBottom}} Instrumental motivations describe using phones to achieve specific goals. These motivations support productivity, scheduling, navigation, and information access (Joo & Sang, 2013). Pragmatic motivations are a subtype of instrumental motivations, focusing on immediate benefits such as reassurance during emergencies or quick information access (Meng et al., 2020). Together, these motivations position smartphones as essential tools for managing everyday life (Wilson et al., 2022). [[File:Online calendar used for scheduling.png|thumb|''Figure 2.'' An example of an online calendar used daily to organise and schedule tasks.|300x300px]]'''Theoretical explanation''' Two psychological models explain these motivations. *The [[wikipedia:Technology_acceptance_model|technology acceptance model]] (TAM): TAM proposes that technology use depends on perceived usefulness and ease of use (Davis, 1989). When phones are both effective and effortless, they are more likely to be integrated into daily routines. This aligns with the [[wikipedia:Theory_of_reasoned_action|theory of reasoned action]], which views attitudes as strong predictors of behaviour (Fishbein & Ajzen, 1975). *The [[wikipedia:Uses_and_gratifications_theory|uses and gratifications theory]] (UGT): UGT views smartphone users as active decision-makers who adopt media to fulfil personal needs (Katz et al., 1973). Instrumental use reflects utility-based gratifications, such as finding directions, setting reminders, or contacting help (Park et al., 2009). These models show how technology design and user choice shape instrumental motivation. '''Research evidence''' Instrumental phone use is consistently linked to positive outcomes. Purposeful engagement such as accessing information, improving productivity, and navigating with GPS supports daily functioning (Wilson et al., 2022). For older adults, instrumental use helps coordinate activities and supports both cognitive and social functioning (Wilson et al., 2022). Pragmatic motivations extend these benefits by providing reassurance and safety, especially during emergencies (Meng et al., 2020). From TAM's perspective, these outcomes illustrate how perceived usefulness encourages routine phone behaviour (Davis, 1989). Meng et al. (2020) found that instrumental use is less likely to lead to dependency compared to hedonic or emotional motivations. This suggests instrumental use promotes a balanced engagement with smartphones. However, risks exist. An over-reliance on GPS may impair spatial awareness (Ruginski et al., 2019), and habitual checking of reminders can weaken memory and problem-solving skills (Elhai et al., 2017). UGT helps explain this shift from adaptive to maladaptive outcomes. While users initially select tools for convenience, {{g]} however reliance can turn into habit, diminishing autonomy and flexibility (Kardefelt-Winther, 2014). '''Summary''' Instrumental and pragmatic motivations generally support adaptive outcomes. Phones act as practical assistants, helping people stay organised, informed, and safe. TAM and UGT show that when phones are useful and easy to use, they integrate smoothly into daily life. Yet, the same convenience may reduce independence if it replaces critical skills. These motivations are most beneficial when phones complement rather than replace human capabilities (Joo & Sang, 2013). == Hedonic and entertainment motivations == {{RoundBoxTop|theme=2}}[[File:Girl silhouette.svg|20px|link=]] '''Case example: Sarah''' After a long day of studying, Sarah relaxes by watching videos on TikTok or playing mobile games like Clash of Clans. These activities improve her mood and distract her from her current stress. But sometimes these activities delay her sleep and cut into her study time. {{RoundBoxBottom}} Hedonic motivations describe using phones for enjoyment, escape, and relief from boredom. This includes watching videos, gaming, scrolling [[wikipedia:Social_media|social media]], or listening to music. These activities provide quick pleasure and immersion (Granic et al., 2014). '''Theoretical explanation''' Three psychological perspectives explain how hedonic motivations drive mobile phone use. *The uses and gratifications theory: People actively select media to meet needs such as entertainment, diversion, and relaxation (Katz et al., 1973). Smartphones amplify these gratifications because they combine many entertainment functions in one portable device (Sundar & Limperos, 2013). *[[wikipedia:Self-determination_theory|Self-determination theory (SDT)]]: Hedonic use can satisfy the basic psychological needs for autonomy and competence, enhancing intrinsic motivation (Deci & Ryan, 1985) For example, choosing a playlist supports autonomy. Beating a level in a game provides competence. Sharing a video with friends strengthens relatedness. When these needs are met, hedonic use can enhance wellbeing (Jeno et al., 2017). *The compensatory internet use theory (CIUT): People use online entertainment to cope with stress, loneliness, or unmet needs (Kardefelt-Winther, 2014). For students like Sarah, this may mean escaping academic pressure through binge-watching or gaming. While this coping strategy may provide temporary relief, it can also become maladaptive if it replaces healthier habits like rest or social interaction (Elhai et al., 2019). Together, these theories show that hedonic use is about mood regulation, need fulfilment, and distraction.[[File:Young boy watching a video on his phone.png|thumb|''Figure 3.'' A person enjoying watching a video on their phone.]] '''Research evidence''' Short bursts of gaming or video watching can reduce stress and help recovery from daily strain (Reinecke & Eden, 2016). Adolescents who engage in these activities with peers also report stronger friendships and an increased sense of belonging (Granic et al., 2014). From the perspective of self-determination theory, these hedonic activities satisfy psychological needs for competence and relatedness, supporting wellbeing when used in moderation (Deci & Ryan, 2000). However, risks arise when hedonic use becomes excessive. A meta-analysis by Kuss et al. (2018) found a moderate association between hedonic phone use and poorer sleep quality. This corroborates findings from national survey data. For instance, 70% of Australian teenagers use their phones in bed, with half of them reporting shorter sleep durations (Sleep Health Foundation, 2022). The compensatory internet use theory helps explain this pattern. While entertainment can offer short-term stress relief, excessive reliance may reinforce avoidance coping, negatively affecting wellbeing over time (Elhai et al., 2017). The uses and gratifications theory further clarifies these risks by showing how entertainment use can shift from intentional choice to automatic checking. This diminishes autonomy and reinforces distraction habits (Sundar & Limperos, 2013). Similarly, the self-determination theory suggests that hedonic use dominated by stress or obligation fails to satisfy basic needs and may undermine health (Deci & Ryan, 1985). '''Summary''' Hedonic motivations highlights the double-edged nature of mobile entertainment. When balanced, these activities fulfil psychological needs and aid recovery from stress (Reinecke & Eden, 2016). Conversely, when driven by avoidance or habit, they can impair sleep, learning, and overall wellbeing (Kuss et al., 2018). The impact depends less on the technology itself and more on whether people use it as a balanced form of enjoyment or as a substitute for healthier coping strategies. {{RoundBoxTop|theme=9}} [[File:Thought_bubble.svg|40px|link=]] '''Reflection box: How do you use your phone for entertainment?''' Think about the last time you used your phone just for enjoyment (e.g., watching videos, playing games, scrolling social media). *Did it help you feel more relaxed or energised? *Did it ever interfere with your sleep? *What needs (autonomy, competence, connection) do you think were met by that phone use? {{RoundBoxBottom}} == Social motivations == {{RoundBoxTop|theme=3}} [[File:Girl silhouette.svg|20px|link=]] '''Case example: Taylor''' Taylor recently moved to a new city for university. She uses messaging apps, video calls, and social media to stay in touch with old friends. These interactions help her feel connected to her community, despite the distance. {{RoundBoxBottom}} Taylor’s behaviour reflects social motivations. These motivations stem from the human need for connection, belonging, and validation. Phones allow people to maintain relationships, share updates and feel included regardless of distance. Social motivations include messaging, posting content, and joining online groups. While often rewarding, social use can also create pressure to stay available and can increase stress when users feel excluded (Kim & Lee, 2011). [[File:Online course, fall 2020, Senior Citizens Write Wikipedia.png|thumb|right|''Figure 4''. A group of friends using video calls to socialise with each other.|300x300px]] '''Theoretical explanation''' Three psychological models explain how social motivations drive mobile phone use. *Self-determination theory: SDT identifies relatedness as a basic psychological need, alongside autonomy and competence (Deci & Ryan, 2000). Phones support relatedness by offering frequent contact (Joo & Sang, 2013). However, when connections are pursued out of obligation or fear of exclusion, the benefits of relatedness decline (Kushlev et al., 2016). *Uses and gratifications theory: UGT sees users as active decision-makers who choose media that fulfils needs such as belonging, reassurance, or identity expression (Katz et al., 1973). Phones make this easy by providing instant connection. *Compensatory Internet Use Theory (CIUT): CIUT proposes that people use online communication to compensate for offline social challenges (Kardefelt-Winther, 2014). For example, students may rely on group chats or social media to reduce loneliness or social anxiety. While this can provide temporary comfort, it may also reinforce dependence and reduce engagement in offline interactions. Together, these perspectives suggest that social motivations can be both supportive and anxiety-driven. '''Research evidence''' Research highlights both benefits and risks associated with social phone use. On the positive side, social interactions via smartphones strengthen perceived support and bonding. Tools like messaging, [[wikipedia:Videotelephony|video calls]], and [[wikipedia:Chat_room|group chats]] help reduce loneliness and help students adapt to new environments (Joo & Sang, 2013). Surveys show that sharing humour, updates, and encouragement online is linked with higher wellbeing and a stronger sense of belonging (Mission Australia, 2022). These benefits are strongest when social media use is intentional. Sundar and Limperos (2013) found that focusing on meaningful exchanges rather than constant scrolling reduces loneliness and supports resilience. From the perspective of SDT, this shows how social needs for relatedness can be fulfilled in autonomy-supportive ways (Deci & Ryan, 2000). However, risks arise when social use is excessive or driven by anxiety. [[wikipedia:Fear_of_missing_out|FoMo]] is strongly linked to compulsive checking, increased stress, and sleep disturbances (Przybylski et al., 2013). Longitudinal studies show that students who mainly use phones to alleviate social anxiety report heightened distress over time (Elhai et al., 2017). This aligns with the CIUT, which suggests that digital connection can serve as avoidance coping. It offers temporary relief but reinforces dependence (Kardefelt-Winther, 2014). UGT further explains that repeated reliance on phones for reassurance fosters habitual checking rather than active coping, increasing vulnerability to problematic use (Kuss et al., 2018). '''Summary''' Social motivations demonstrate how phones serve as tools for belonging. When use is selective and autonomy-supportive, phones enhance wellbeing by fulfilling relatedness needs (Deci & Ryan, 2000). Conversely, when driven by FoMo or avoidance, social phone use may foster stress, dependence, and reduced offline interaction (Elhai et al., 2019). A positive balance depends on whether social phone use supports authentic connection or substitutes for healthier coping strategies. == Emotional and mood regulatory motivations == {{RoundBoxTop|theme=4}} [[File:Boy from vector.svg|30px|link=]] '''Case example: Sam''' Sam often feels anxious before giving class presentations. To cope, he checks his phone for supportive messages and scrolls through Instagram to distract himself. This brings temporary relief but prevents him from addressing the root of his anxiety. {{RoundBoxBottom}} Sam’s behaviour reflects emotional and mood regulatory motivations, where phones are used to manage stress, loneliness, anxiety, sadness, or boredom. Smartphones provide immediate outlets for distraction, reassurance, or self-expression. This helps stabilise mood in the short term. These motivations stem from the basic psychological drive to regulate emotions and regain a sense of control. However, reliance on phones can shift from adaptive coping to maladaptive dependence when overused. '''Theoretical explanation''' Three psychological models explain these dynamics. *[[wikipedia:Emotional_self-regulation|Emotion regulation]] theory: Gross (1998) distinguishes strategies such as distraction, reappraisal, and suppression. Phones support distraction (e.g., scrolling feeds) and can encourage reappraisal by offering uplifting or humorous content. *[[wikipedia:Mood_management_theory|Mood management theory]]: Zillmann (1988) suggests people choose media to reduce negative states or maintain positive ones. Smartphones provide instant access to entertainment, games, and social contact, making them powerful tools for mood adjustment. *Compensatory internet use theory: Kardefelt-Winther (2014) proposes that individuals turn to media to offset offline stressors. While this can relieve tension, it may also fuel avoidance if deeper problems remain unresolved. Together, these theories explain why emotionally motivated phone use can bring short-term relief but also carry long-term risks. '''Research evidence''' Moderate use of relaxation apps, mindfulness tools, or supportive messaging can reduce stress and improve wellbeing in the short term (Reinecke & Eden, 2016). Social sharing and online self-expression offer [[wikipedia:Catharsis|catharsis]] and strengthen social bonds, consistent with mood management theory (Kim & Lee, 2011). Additional evidence shows that reappraisal through positive online content may enhance emotional resilience (Park & Valenzuela, 2009). However, risks arise when emotional regulation relies too heavily on smartphones. Escaping stress through constant phone use has been linked to procrastination, avoidance, and increased stress (Elhai et al., 2019). Heavy nighttime use is consistently linked with poor sleep quality and heightened anxiety (Sleep Health Foundation, 2022). Longitudinal studies further show that depending on phones as a primary coping mechanism predicts worsening depressive symptoms over time, especially in adolescents (Kuss et al., 2018). These findings illustrate the shift from adaptive distraction to maladaptive dependence when stressors remain unaddressed. [[File:Young boy struggling to sleep.png|thumb|''Figure 5.'' Illustration of a young boy struggling to fall asleep at night because he is using his phone before bed.]]'''Summary''' Emotion regulation theory highlights how phones provide quick access to distraction and reappraisal. Mood management theory explains why people seek uplifting or entertaining content. Compensatory internet use theory clarifies why these strategies sometimes slip into avoidance and dependency. Using digital tools is most beneficial when they complement healthy offline coping strategies such as problem-solving, rest, and social support, rather than replacing them (Kushlev et al., 2016). == Practical implications == To promote healthier smartphone use, strategies must address the different motivations that drive behaviour. Grounding these strategies in psychological theory ensures that they move beyond surface-level advice and instead build lasting skills for wellbeing. By tailoring strategies, smartphone use can shift from automatic or avoidant behaviours to intentional habits that enhance autonomy, competence, and relatedness (Deci & Ryan, 2000). '''Instrumental use''' Smartphones are valuable tools for organisation, navigation, and learning. Using calendar apps, focus timers, and note-taking platforms can strengthen autonomy and competence (Deci & Ryan, 2000). Practical strategies could include driving offline routes to maintain spatial awareness while reducing an over-reliance on devices like GPS (Ruginski et al., 2019). Also, reflecting on which apps genuinely support goals helps build self-regulation (Hadlington, 2015). Workplaces, schools, and families can also encourage digital literacy training to help people use apps more intentionally, aligning with self-regulation theory, which emphasises feedback and planning in achieving goals. '''Hedonic use''' Phones provide entertainment and while these activities can improve mood, excessive use can disrupt sleep and concentration (Exelmans & Van den Bulck, 2016). Practical strategies include setting app timers, scheduling intentional leisure breaks, and prioritising stimulating media over passive media (Sundar & Limperos, 2013). Choosing creativity-focused or interactive content enhances wellbeing. Also reducing device use before sleep supports circadian rhythms and reduces fatigue (Exelmans & Van den Bulck, 2016). From the perspective of mood management theory (Zillmann, 1988), these strategies work by channelling hedonic needs into intentional rather than automatic behaviours. This allows people to enjoy pleasure while minimising costs to health and productivity. '''Social use''' Connection with others is a central reason for phone use. Structured strategies, such as curated group chats, online communities, or family check-ins, allow people to maintain relationships without constant checking. Intentional social use through prioritising direct communication over passive scrolling strengthens bonds and wellbeing (Beyens et al., 2020). Reducing notifications or batching social media checks can lower compulsive behaviours (Przybylski et al., 2013). Reflecting on whether engagement arises from genuine interest or obligation helps protect autonomy in relationships (Kushlev et al., 2016). Compensatory Internet Use Theory (Kardefelt-Winther, 2014) suggests that many turn to digital connection to offset stress or loneliness. Pairing online interactions with offline opportunities for belonging, such as community groups or shared hobbies, can reduce dependence while still supporting relatedness. [[File:A young girl listening to music on her phone.png|thumb|''Figure 6.'' An illustration of a young girl listening to music on her mobile phone.]] '''Emotional use''' Smartphones are often used to cope with stress, sadness, or boredom. Adaptive strategies include guided relaxation apps, calming audio, or mood-tracking tools, which can reduce stress in the short term (Reinecke & Eden, 2016). However, coping is most effective when digital tools are paired with offline support such as rest, social support, or problem-solving (Gross, 1998). Reflective practices such as asking “Is this helping me cope, or am I avoiding?” can prevent avoidance cycles linked with poor sleep and heightened anxiety (Elhai et al., 2017). Mood management theory (Zillmann, 1988) {{ic|Not in References}} explains why uplifting content helps regulate emotions. While compensatory internet use theory highlights the risks of relying on avoidance strategies without addressing underlying stressors. ==Conclusion== Smartphone use is driven by instrumental, hedonic, social, and emotional motivations, reflecting basic psychological needs. Psychological theories like TAM, SDT, and UGT show that phones are not inherently good or bad. Their impact depends on the motivations guiding engagement. Smartphones can support productivity, enjoyment, connection, and stress relief, but the same patterns may also foster avoidance, dependency, and reduced wellbeing. This dual role highlights the importance of intentional use. Hedonic use is most rewarding when balanced, and social connection most beneficial when authentic. Instrumental and emotional use require reflection to avoid over-reliance. Recognising personal motivations helps individuals use smartphones as tools for growth, protecting autonomy, rest, and wellbeing. By understanding these dynamics, people can shape technology into an ally for resilience rather than a source of distraction. ==See also== * [[Motivation and emotion/Book/2021/Boredom and technology addiction|Boredom and technology addiction]] (Book chapter, 2021) * [[Motivation and emotion/Book/2016/Mobile phone addiction|Mobile phone addiction]] (Book chapter, 2016) * [[Motivation and emotion/Book/2017/Mobile phone addiction|Mobile phone addiction]] (Book chapter, 2017) * [[Motivation and emotion/Book/2023/Mobile phone use motivation|Mobile phone use motivation]] (Book chapter, 2023) ==References== {{Hanging indent|1= Beyens, I., Pouwels, J.

A woman beside him scrolls through her messages. Across the aisle, a student types reminders into a calendar app. Next to you, a man endlessly scrolls through social media updates. What draws each of these people to their phone? Is it comfort, connection, distraction, or control? These are everyday actions, yet behind them lie hidden motivations that shape our relationship with smartphones. {{RoundBoxBottom}} [[wikipedia:Mobile_phone|Mobile phones]] are central to modern life, influencing how people work, connect, and cope with [[wikipedia:Stress_(biology)|stress]]. Their use is driven by complex psychological needs that affect daily [[wikipedia:Behavior|behaviour]] and [[wikipedia:Well-being|wellbeing]]. Understanding these [[wikipedia:Motivation|motivations]] reveals why people engage with phones in unique ways, and why these behaviours can bring both benefits and challenges. [[wikipedia:Smartphone|Smartphones]] enhance productivity, entertainment, and social bonds. Yet, excessive or compulsive use can lead to [[wikipedia:Procrastination|procrastination]], [[wikipedia:Anxiety|anxiety]], and emotional [[wikipedia:Avoidance_coping|avoidance]]. This chapter explores how motivations shape phone use and offers strategies for healthier, intentional smartphone use that supports wellbeing. {{RoundBoxTop|theme=3}} '''Focus questions''' * What motivates people to use smartphones in their daily lives? * What psychological theories explain these motivations? * How do different motivations impact wellbeing in positive and negative ways? * What strategies can encourage mindful and beneficial phone use? {{RoundBoxBottom}} == Key motivations for mobile phone use == People use mobile phones to satisfy different psychological needs. These needs are typically categorised as instrumental (task-focused), hedonic (pleasure-oriented), social (connection-based), and emotional (coping-related) (Sundar & Limperos, 2013). These motivations explain how phones are integrated into daily life and how they influence wellbeing (Davis, 1989). == Instrumental and pragmatic motivations == {{RoundBoxTop|theme=1}}[[File:Boy from vector.svg|30px|link=]] '''Case example: Alex''' Alex starts each morning by checking the weather app, navigating traffic with GPS, reviewing lecture notes, and setting assignments reminders. Each action is purposeful and task-oriented. His smartphone works as a practical assistant, helping him manage academic and daily tasks. {{RoundBoxBottom}} Instrumental motivations describe using phones to achieve specific goals. These motivations support productivity, scheduling, navigation, and information access (Joo & Sang, 2013). Pragmatic motivations are a subtype of instrumental motivations, focusing on immediate benefits such as reassurance during emergencies or quick information access (Meng et al., 2020). Together, these motivations position smartphones as essential tools for managing everyday life (Wilson et al., 2022). [[File:Online calendar used for scheduling.png|thumb|''Figure 2.'' An example of an online calendar used daily to organise and schedule tasks.|300x300px]]'''Theoretical explanation''' Two psychological models explain these motivations. *The [[wikipedia:Technology_acceptance_model|technology acceptance model]] (TAM): TAM proposes that technology use depends on perceived usefulness and ease of use (Davis, 1989). When phones are both effective and effortless, they are more likely to be integrated into daily routines. This aligns with the [[wikipedia:Theory_of_reasoned_action|theory of reasoned action]], which views attitudes as strong predictors of behaviour (Fishbein & Ajzen, 1975). *The [[wikipedia:Uses_and_gratifications_theory|uses and gratifications theory]] (UGT): UGT views smartphone users as active decision-makers who adopt media to fulfil personal needs (Katz et al., 1973). Instrumental use reflects utility-based gratifications, such as finding directions, setting reminders, or contacting help (Park et al., 2009). These models show how technology design and user choice shape instrumental motivation. '''Research evidence''' Instrumental phone use is consistently linked to positive outcomes. Purposeful engagement such as accessing information, improving productivity, and navigating with GPS supports daily functioning (Wilson et al., 2022). For older adults, instrumental use helps coordinate activities and supports both cognitive and social functioning (Wilson et al., 2022). Pragmatic motivations extend these benefits by providing reassurance and safety, especially during emergencies (Meng et al., 2020). From TAM's perspective, these outcomes illustrate how perceived usefulness encourages routine phone behaviour (Davis, 1989). Meng et al. (2020) found that instrumental use is less likely to lead to dependency compared to hedonic or emotional motivations. This suggests instrumental use promotes a balanced engagement with smartphones. However, risks exist. An over-reliance on GPS may impair spatial awareness (Ruginski et al., 2019), and habitual checking of reminders can weaken memory and problem-solving skills (Elhai et al., 2017). UGT helps explain this shift from adaptive to maladaptive outcomes. While users initially select tools for convenience, {{g]} however reliance can turn into habit, diminishing autonomy and flexibility (Kardefelt-Winther, 2014). '''Summary''' Instrumental and pragmatic motivations generally support adaptive outcomes. Phones act as practical assistants, helping people stay organised, informed, and safe. TAM and UGT show that when phones are useful and easy to use, they integrate smoothly into daily life. Yet, the same convenience may reduce independence if it replaces critical skills. These motivations are most beneficial when phones complement rather than replace human capabilities (Joo & Sang, 2013). == Hedonic and entertainment motivations == {{RoundBoxTop|theme=2}}[[File:Girl silhouette.svg|20px|link=]] '''Case example: Sarah''' After a long day of studying, Sarah relaxes by watching videos on TikTok or playing mobile games like Clash of Clans. These activities improve her mood and distract her from her current stress. But sometimes these activities delay her sleep and cut into her study time. {{RoundBoxBottom}} [[File:Young girl Using Her Phone.jpg|thumb|''Figure 3.'' A young woman engaged in using her mobile phone.]] Hedonic motivations describe using phones for enjoyment, escape, and relief from boredom. This includes watching videos, gaming, scrolling [[wikipedia:Social_media|social media]], or listening to music. These activities provide quick pleasure and immersion (Granic et al., 2014). '''Theoretical explanation''' Three psychological perspectives explain how hedonic motivations drive mobile phone use. *The uses and gratifications theory: People actively select media to meet needs such as entertainment, diversion, and relaxation (Katz et al., 1973). Smartphones amplify these gratifications because they combine many entertainment functions in one portable device (Sundar & Limperos, 2013). *[[wikipedia:Self-determination_theory|Self-determination theory (SDT)]]: Hedonic use can satisfy the basic psychological needs for autonomy and competence, enhancing intrinsic motivation (Deci & Ryan, 1985) For example, choosing a playlist supports autonomy. Beating a level in a game provides competence. Sharing a video with friends strengthens relatedness. When these needs are met, hedonic use can enhance wellbeing (Jeno et al., 2017). *The compensatory internet use theory (CIUT): People use online entertainment to cope with stress, loneliness, or unmet needs (Kardefelt-Winther, 2014). For students like Sarah, this may mean escaping academic pressure through binge-watching or gaming. While this coping strategy may provide temporary relief, it can also become maladaptive if it replaces healthier habits like rest or social interaction (Elhai et al., 2019). Together, these theories show that hedonic use is about mood regulation, need fulfilment, and distraction. '''Research evidence''' Short bursts of gaming or video watching can reduce stress and help recovery from daily strain (Reinecke & Eden, 2016). Adolescents who engage in these activities with peers also report stronger friendships and an increased sense of belonging (Granic et al., 2014). From the perspective of self-determination theory, these hedonic activities satisfy psychological needs for competence and relatedness, supporting wellbeing when used in moderation (Deci & Ryan, 2000). However, risks arise when hedonic use becomes excessive. A meta-analysis by Kuss et al. (2018) found a moderate association between hedonic phone use and poorer sleep quality. This corroborates findings from national survey data. For instance, 70% of Australian teenagers use their phones in bed, with half of them reporting shorter sleep durations (Sleep Health Foundation, 2022). The compensatory internet use theory helps explain this pattern. While entertainment can offer short-term stress relief, excessive reliance may reinforce avoidance coping, negatively affecting wellbeing over time (Elhai et al., 2017). The uses and gratifications theory further clarifies these risks by showing how entertainment use can shift from intentional choice to automatic checking. This diminishes autonomy and reinforces distraction habits (Sundar & Limperos, 2013). Similarly, the self-determination theory suggests that hedonic use dominated by stress or obligation fails to satisfy basic needs and may undermine health (Deci & Ryan, 1985). '''Summary''' Hedonic motivations highlights the double-edged nature of mobile entertainment. When balanced, these activities fulfil psychological needs and aid recovery from stress (Reinecke & Eden, 2016). Conversely, when driven by avoidance or habit, they can impair sleep, learning, and overall wellbeing (Kuss et al., 2018). The impact depends less on the technology itself and more on whether people use it as a balanced form of enjoyment or as a substitute for healthier coping strategies. {{RoundBoxTop|theme=9}} [[File:Thought_bubble.svg|40px|link=]] '''Reflection box: How do you use your phone for entertainment?''' Think about the last time you used your phone just for enjoyment (e.g., watching videos, playing games, scrolling social media). *Did it help you feel more relaxed or energised? *Did it ever interfere with your sleep? *What needs (autonomy, competence, connection) do you think were met by that phone use? {{RoundBoxBottom}} == Social motivations == {{RoundBoxTop|theme=3}} [[File:Girl silhouette.svg|20px|link=]] '''Case example: Taylor''' Taylor recently moved to a new city for university. She uses messaging apps, video calls, and social media to stay in touch with old friends. These interactions help her feel connected to her community, despite the distance. {{RoundBoxBottom}} Taylor’s behaviour reflects social motivations. These motivations stem from the human need for connection, belonging, and validation. Phones allow people to maintain relationships, share updates and feel included regardless of distance. Social motivations include messaging, posting content, and joining online groups. While often rewarding, social use can also create pressure to stay available and can increase stress when users feel excluded (Kim & Lee, 2011). [[File:Online course, fall 2020, Senior Citizens Write Wikipedia.png|thumb|right|''Figure 4''. A group of friends using video calls to socialise with each other.|300x300px]] '''Theoretical explanation''' Three psychological models explain how social motivations drive mobile phone use. *Self-determination theory: SDT identifies relatedness as a basic psychological need, alongside autonomy and competence (Deci & Ryan, 2000). Phones support relatedness by offering frequent contact (Joo & Sang, 2013). However, when connections are pursued out of obligation or fear of exclusion, the benefits of relatedness decline (Kushlev et al., 2016). *Uses and gratifications theory: UGT sees users as active decision-makers who choose media that fulfils needs such as belonging, reassurance, or identity expression (Katz et al., 1973). Phones make this easy by providing instant connection. *Compensatory Internet Use Theory (CIUT): CIUT proposes that people use online communication to compensate for offline social challenges (Kardefelt-Winther, 2014). For example, students may rely on group chats or social media to reduce loneliness or social anxiety. While this can provide temporary comfort, it may also reinforce dependence and reduce engagement in offline interactions. Together, these perspectives suggest that social motivations can be both supportive and anxiety-driven. '''Research evidence''' Research highlights both benefits and risks associated with social phone use. On the positive side, social interactions via smartphones strengthen perceived support and bonding. Tools like messaging, [[wikipedia:Videotelephony|video calls]], and [[wikipedia:Chat_room|group chats]] help reduce loneliness and help students adapt to new environments (Joo & Sang, 2013). Surveys show that sharing humour, updates, and encouragement online is linked with higher wellbeing and a stronger sense of belonging (Mission Australia, 2022). These benefits are strongest when social media use is intentional. Sundar and Limperos (2013) found that focusing on meaningful exchanges rather than constant scrolling reduces loneliness and supports resilience. From the perspective of SDT, this shows how social needs for relatedness can be fulfilled in autonomy-supportive ways (Deci & Ryan, 2000). However, risks arise when social use is excessive or driven by anxiety. [[wikipedia:Fear_of_missing_out|FoMo]] is strongly linked to compulsive checking, increased stress, and sleep disturbances (Przybylski et al., 2013). Longitudinal studies show that students who mainly use phones to alleviate social anxiety report heightened distress over time (Elhai et al., 2017). This aligns with the CIUT, which suggests that digital connection can serve as avoidance coping. It offers temporary relief but reinforces dependence (Kardefelt-Winther, 2014). UGT further explains that repeated reliance on phones for reassurance fosters habitual checking rather than active coping, increasing vulnerability to problematic use (Kuss et al., 2018). '''Summary''' Social motivations demonstrate how phones serve as tools for belonging. When use is selective and autonomy-supportive, phones enhance wellbeing by fulfilling relatedness needs (Deci & Ryan, 2000). Conversely, when driven by FoMo or avoidance, social phone use may foster stress, dependence, and reduced offline interaction (Elhai et al., 2019). A positive balance depends on whether social phone use supports authentic connection or substitutes for healthier coping strategies. == Emotional and mood regulatory motivations == {{RoundBoxTop|theme=4}} [[File:Boy from vector.svg|30px|link=]] '''Case example: Sam''' Sam often feels anxious before giving class presentations. To cope, he checks his phone for supportive messages and scrolls through Instagram to distract himself. This brings temporary relief but prevents him from addressing the root of his anxiety. {{RoundBoxBottom}} Sam’s behaviour reflects emotional and mood regulatory motivations, where phones are used to manage stress, loneliness, anxiety, sadness, or boredom. Smartphones provide immediate outlets for distraction, reassurance, or self-expression. This helps stabilise mood in the short term. These motivations stem from the basic psychological drive to regulate emotions and regain a sense of control. However, reliance on phones can shift from adaptive coping to maladaptive dependence when overused. '''Theoretical explanation''' Three psychological models explain these dynamics. *[[wikipedia:Emotional_self-regulation|Emotion regulation]] theory: Gross (1998) distinguishes strategies such as distraction, reappraisal, and suppression. Phones support distraction (e.g., scrolling feeds) and can encourage reappraisal by offering uplifting or humorous content. *[[wikipedia:Mood_management_theory|Mood management theory]]: Zillmann (1988) suggests people choose media to reduce negative states or maintain positive ones. Smartphones provide instant access to entertainment, games, and social contact, making them powerful tools for mood adjustment. *Compensatory internet use theory: Kardefelt-Winther (2014) proposes that individuals turn to media to offset offline stressors. While this can relieve tension, it may also fuel avoidance if deeper problems remain unresolved. Together, these theories explain why emotionally motivated phone use can bring short-term relief but also carry long-term risks. '''Research evidence''' Moderate use of relaxation apps, mindfulness tools, or supportive messaging can reduce stress and improve wellbeing in the short term (Reinecke & Eden, 2016). Social sharing and online self-expression offer [[wikipedia:Catharsis|catharsis]] and strengthen social bonds, consistent with mood management theory (Kim & Lee, 2011). Additional evidence shows that reappraisal through positive online content may enhance emotional resilience (Park & Valenzuela, 2009). However, risks arise when emotional regulation relies too heavily on smartphones. Escaping stress through constant phone use has been linked to procrastination, avoidance, and increased stress (Elhai et al., 2019). Heavy nighttime use is consistently linked with poor sleep quality and heightened anxiety (Sleep Health Foundation, 2022). Longitudinal studies further show that depending on phones as a primary coping mechanism predicts worsening depressive symptoms over time, especially in adolescents (Kuss et al., 2018). These findings illustrate the shift from adaptive distraction to maladaptive dependence when stressors remain unaddressed. [[File:Young boy struggling to sleep.png|thumb|''Figure 5.'' Illustration of a young boy struggling to fall asleep at night because he is using his phone before bed.]]'''Summary''' Emotion regulation theory highlights how phones provide quick access to distraction and reappraisal. Mood management theory explains why people seek uplifting or entertaining content. Compensatory internet use theory clarifies why these strategies sometimes slip into avoidance and dependency. Using digital tools is most beneficial when they complement healthy offline coping strategies such as problem-solving, rest, and social support, rather than replacing them (Kushlev et al., 2016). == Practical implications == To promote healthier smartphone use, strategies must address the different motivations that drive behaviour. Grounding these strategies in psychological theory ensures that they move beyond surface-level advice and instead build lasting skills for wellbeing. By tailoring strategies, smartphone use can shift from automatic or avoidant behaviours to intentional habits that enhance autonomy, competence, and relatedness (Deci & Ryan, 2000). '''Instrumental use''' Smartphones are valuable tools for organisation, navigation, and learning. Using calendar apps, focus timers, and note-taking platforms can strengthen autonomy and competence (Deci & Ryan, 2000). Practical strategies could include driving offline routes to maintain spatial awareness while reducing an over-reliance on devices like GPS (Ruginski et al., 2019). Also, reflecting on which apps genuinely support goals helps build self-regulation (Hadlington, 2015). Workplaces, schools, and families can also encourage digital literacy training to help people use apps more intentionally, aligning with self-regulation theory, which emphasises feedback and planning in achieving goals. '''Hedonic use''' Phones provide entertainment and while these activities can improve mood, excessive use can disrupt sleep and concentration (Exelmans & Van den Bulck, 2016). Practical strategies include setting app timers, scheduling intentional leisure breaks, and prioritising stimulating media over passive media (Sundar & Limperos, 2013). Choosing creativity-focused or interactive content enhances wellbeing. Also reducing device use before sleep supports circadian rhythms and reduces fatigue (Exelmans & Van den Bulck, 2016). From the perspective of mood management theory (Zillmann, 1988), these strategies work by channelling hedonic needs into intentional rather than automatic behaviours. This allows people to enjoy pleasure while minimising costs to health and productivity. '''Social use''' Connection with others is a central reason for phone use. Structured strategies, such as curated group chats, online communities, or family check-ins, allow people to maintain relationships without constant checking. Intentional social use through prioritising direct communication over passive scrolling strengthens bonds and wellbeing (Beyens et al., 2020). Reducing notifications or batching social media checks can lower compulsive behaviours (Przybylski et al., 2013). Reflecting on whether engagement arises from genuine interest or obligation helps protect autonomy in relationships (Kushlev et al., 2016). Compensatory Internet Use Theory (Kardefelt-Winther, 2014) suggests that many turn to digital connection to offset stress or loneliness. Pairing online interactions with offline opportunities for belonging, such as community groups or shared hobbies, can reduce dependence while still supporting relatedness. [[File:A young girl listening to music on her phone.png|thumb|''Figure 6.'' An illustration of a young girl listening to music on her mobile phone.]] '''Emotional use''' Smartphones are often used to cope with stress, sadness, or boredom. Adaptive strategies include guided relaxation apps, calming audio, or mood-tracking tools, which can reduce stress in the short term (Reinecke & Eden, 2016). However, coping is most effective when digital tools are paired with offline support such as rest, social support, or problem-solving (Gross, 1998). Reflective practices such as asking “Is this helping me cope, or am I avoiding?” can prevent avoidance cycles linked with poor sleep and heightened anxiety (Elhai et al., 2017). Mood management theory (Zillmann, 1988) {{ic|Not in References}} explains why uplifting content helps regulate emotions. While compensatory internet use theory highlights the risks of relying on avoidance strategies without addressing underlying stressors. ==Conclusion== Smartphone use is driven by instrumental, hedonic, social, and emotional motivations, reflecting basic psychological needs. Psychological theories like TAM, SDT, and UGT show that phones are not inherently good or bad. Their impact depends on the motivations guiding engagement. Smartphones can support productivity, enjoyment, connection, and stress relief, but the same patterns may also foster avoidance, dependency, and reduced wellbeing. This dual role highlights the importance of intentional use. Hedonic use is most rewarding when balanced, and social connection most beneficial when authentic. Instrumental and emotional use require reflection to avoid over-reliance. Recognising personal motivations helps individuals use smartphones as tools for growth, protecting autonomy, rest, and wellbeing. By understanding these dynamics, people can shape technology into an ally for resilience rather than a source of distraction. ==See also== * [[Motivation and emotion/Book/2021/Boredom and technology addiction|Boredom and technology addiction]] (Book chapter, 2021) * [[Motivation and emotion/Book/2016/Mobile phone addiction|Mobile phone addiction]] (Book chapter, 2016) * [[Motivation and emotion/Book/2017/Mobile phone addiction|Mobile phone addiction]] (Book chapter, 2017) * [[Motivation and emotion/Book/2023/Mobile phone use motivation|Mobile phone use motivation]] (Book chapter, 2023) ==References== {{Hanging indent|1= Beyens, I., Pouwels, J.

You have always enjoyed your job, the work culture is very positive, you enjoy a full hour long lunch time which allows you to go for a walk outside everyday, and you feel good about working hard and performing for your supervisors. One day you are told a new CEO will take over, a CEO with a reputation for strong leadership and high level performance. A few months in, you soon realise the CEO prioritises profits above all else, leading to staff cuts and increased workloads. You have begun working overtime without pay, skipping breaks to ensure avoiding being labeled as lazy or underperforming. The pressure quickly feels immense and the positive work culture you once enjoyed has disappeared, leaving employee morale low. Over time, you begin to notice that the performance quality and customer service has dropped significantly. Meanwhile, management remains focused on cost-cutting and pushing employees harder and harder. Eventually, customers express unhappiness for the lack of good service the company once had, performance has noticeably dropped, and the company's reputation suffers, ultimately revealing the unfortunate consequences in its relentless bottom-line mentality. {{RoundBoxBottom}} A bottom-line mentality (BLM) has been defined as “1-dimensional thinking that revolves around securing bottom-line outcomes to the neglect of competing priorities” (Greenbaum et al., 2012). It is often, but not always, showcased in an organisational setting, where a tunnel vision focus on achieving the bottom-line sees the disregard of competing work and life priorities (Greenbaum et al., 2023). The term “bottom line” is typically described as the “results that count” or the “final summing up” within its particular context (Wolfe, 1988). For example, in a workplace setting, the bottom-line is usually defined in terms of performance and financial outcomes which implicate the success of the organisation or employee. However, the bottom line ''mentality'' is a concept reflecting a narrow frame of mind with a tunnel vision focus on achieving the outcomes which support an individual or organisation’s financial viability and success (Greenbaum et al., 20120). As such, the BLM has been heavily researched in this area, identifying both favourable (e.g., increased performance outcomes (Babalola et al., 2020)) and unfavourable outcomes (e.g., unethical conduct (Ge, 2018)). {{RoundBoxTop|theme=3}} '''Focus questions:''' * What is the relationship between bottom-line mentality and motivation? * What are the positive and negative implications of a bottom-line mentality? * How can a focus on the bottom-line enhance motivation in some contexts while undermining it in others? {{RoundBoxBottom}} ==A bottom-line mentality in the workplace== BLM has been heavily focused in the context of organisational settings, as a company’s success and longevity are driven by its economic well-being and ability to maintain profitability (Carroll, 1991). Likewise, existing literature exploring BLM reveals an intertwined relationship between employee and organisation. Employees achieving their own bottom-line metrics (e.g., reaching X target, selling X products) benefits the organisation’s profitability, the same way the organisation achieving their bottom-line metrics (e.g., increasing shareholder value) positively affects employees (e.g., shared profits, job security) (Greenbaum et al., 2023). [[File:3D Team Leadership Arrow Concept.jpg|thumb|Figure 2. Influence of leadership]] === Leadership === The [[w:leader-member_exchange_theory|leader-member exchange]] (LMX) is an exchange process between supervisors and their subordinates, where leaders establish either high or low quality relationships with employees. This essentially leads to increased or decreased effort, loyalty, and performance (Dionne et al., 2010), which has been found to be reflective in a BLM in both parties, highlighting the importance of [[Motivation and emotion/Book/2023/Effective leadership|leadership]] styles in the workplace (Quade et al., 2019). Research reveals the impact of LMX, as supervisor behaviours and attitudes play a key role in shaping employee’s attitudes and behaviours, often reflecting that of their superiors (e.g., Duffy et al., 2002). Hence, leaders with a high BLM display a one-dimensional leadership approach, almost exclusively focusing on reaching organisational targets and goals. As such, employee wellbeing, psychological safety, learning, and collaboration is neglected. This style of leadership fails to provide the support necessary to encourage intrinsic motivation necessary for high performance and happy employees (Lin et al., 2022). === Employee performance === In the context of BLM, employee performance and productivity is identified to be greatly dependent on the LMX relationship with the supervisor, which is further complicated by the employee’s individual BLM, regardless if it matches or misaligns with their supervisor, essentially reflecting in their performance. This is important as extant research shows how supervisor BLM impacts employee emotions and subsequent behaviours (Bonner et al., 2017), as well as employee BLM effects disfavourable employee behaviours (Eissa et al., 2020). Quade and colleagues{{g}} (2019) findings supported much of the existing literature, suggesting that employees suffer when their supervisor has a high BLM, regardless if their own BLM is high or low. They found that when employees and supervisors alike had a high BLM, the negative effect on performance was not mitigated, only buffered, revealing that no degree of supervisor BLM is particularly beneficial. == Outcomes and implications associated with a bottom-line mentality == A BLM results in a wide range of behavioural and performance outcomes, as the mentality is constructed around achieving certain goals. As such, positive and negative implications may arise, both revealing short-term and long-term consequences. === Negative implications === Kamran and colleagues (2022) propose that a majority of unethical workplace practices, such as workplace cheating, is caused by undue performance pressure from supervisors which create a highly competitive workplace environment driven by a BLM. As such, several disfavourable BLM-related behaviours are likely to express themselves, such as increased coworker undermining (Greenbaum et al., 2012), abusive supervisions (Mawrtiz et al., 2017), and unethical behaviours in the workplace (Mesdaghinia et al., 2019). While these behaviours are highly problematic in a workplace setting, they risk reflecting negatively for individuals on a cognitive and emotional level. For example, Mitchell et al. (2018) discusses how a BLM triggers workaholism, leading to psychological entitlement. This may be equally as dangerous as performance pressure leading to anger, triggering self-protection, leading to self-serving cognitions, and then resulting in individuals engaging in unethical behaviours for self-gain. Although these behaviours are showcased in the process of bottom-line attainment, and may be deemed as “worthwhile” for company performance, this is often not the case. High BLM supervisors solely signal the importance of task performance to their subordinates, and in turn, they create low quality relationships. Therefore, the employees are likely to reciprocate by withholding what BLM supervisors desire most - performance and results (Mawritz et al., 2017). As such, this desire for bottom-line attainment ultimately inflicts harm to the organisation itself (Mitchell et al., 2018). === Positive implications === Despite the seemingly extensive breadth of negative implications that can arise in a workplace characterised by a bottom-line attainment, extant research reveals evidence to support a BLM and suggests positive implications exist. This is likely due to individual differences among employees and supervisors, as not all subordinates working for a BLM supervisor exhibiting a high BLM demonstrate the same unethical behaviours (Farasat et al., 2020). Research has found that a focus on bottom-line attainment can in fact lead to an enhanced organisational performance and employee productivity (Friedman, 2007), increased task performance from employees (Babalola et al., 2020), elevated shareholder value (Farasat et al., 2020), and essentially, overall organisational success - the incentivising goal of a BLM (Davidsson et al., 2009). Quade et al. (2019) & Lim et al.'s (2021) research reveals a summary of positive implications derived from a BLM when the supervisor and employee share similar goals, including clarity and focus on process and outcomes, and enhanced task efficiency. However, they emphasise that these are short-term successes, and are often overshadowed by long-term negative consequences. {{tip|Food for thought... *Are the positive outcomes related with a BLM worth the costs of the negative implications? *Is it truly possible for leaders to foster a positive workplace environment for employees when demonstrating a high BLM themselves? *Are particular industries or fields at a higher risk of negative BLM consequences compared to others? }} == Motivational dynamics of a bottom-line mentality == Several motivational-related theories have been considered when exploring individuals’ motives behind engaging in a BLM. It is clear that there are several influencing factors that can contribute to a BLM (e.g. Quade et al., 2019; Lin et al., 2022). Likewise, extant research suggests the interpersonal dynamic between supervisors and employees can heavily contribute to the expression and motivation of a BLM. === Social information processing theory === Social information processing theory (SIP) (Salancik & Pfeffer, 1978) is often discussed in the context of a workplace, exploring what motivates individuals to make decisions and form attitudes in a social context. The theory suggests that individuals will shape their attitudes and behaviours based on the social information provided to them in their organisation's environment. Lin et al. (2021) use SIP as a framework in their research to explore how BLM impacts a team’s motivation. In the case of a high BLM supervisor, employees are more likely to internalise the idea that their primary goal is to avoid failure and achieve the bottom-line at all costs based on social cues emphasising profit, cognitive processing of BLM norms, and behavioural adaption. As such, teams are at risk of developing a team performance avoidance goal orientation, a shared motivational state characterised by an obsession of avoiding mistakes and achieving success, which comes with its own risks. Thus, SIP can help explain how individuals can be influenced by their social environment, which is a key enforcer and perpetuator if the BLM mindset within teams or entire organisations. === Social exchange theory and reciprocity === Social exchange theory (Blau, 1964) explores the interaction between social relationships and structures, viewing interpersonal relations in terms of costs and benefits exchanged between parties. The theory helps to explain behaviours of individuals based on the concept of reciprocity - if one party provides something valuable, the other is expected to reciprocate. This can often result in transactional, self-interested exchanges which weaken long-term relationships, trust, and positive organisational culture. As such, a high BLM supervisor is a poor exchange partner, since they prioritise bottom-line over employee wellbeing, essentially resulting in low LMX. Quade et al. (2019) suggests this expresses itself in the form of negative reciprocity, where employees withhold effort and reduce performance. The absence of positive LMX diminishes employee’s intrinsic motivation, leading to lower task performance. While BLM focuses on maximising financial gain, individuals may overlook the long-term value of maintaining healthy, equitable social exchanges, ultimately harming the wellbeing of both individuals and organisations. [[File:Goal orientation theory.png|thumb|282x282px|Figure 4. 2x2 achievement goal framework]] === Goal orientation theory and expectancy theory === Lin et al. (2021) attribute [[w:Goal_orientation|goal orientation theory]] (VandeWalle, 1997) to explain the shift from intrinsic to extrinsic motivation under a BLM supervisor. The theory recognises the difference between performance-approach goals (seeking to demonstrate competence) and performance-avoidance goals (seeking to avoid failure) (see fig. 4), which can be expressed on both an individual and group level. A supervisor high in BLM can cause their subordinates to adopt a performance avoidance goal orientation within their groups. To avoid failure, teams experience fear-based motivation, inhibiting optimal employee wellbeing and team performance in order to simply achieve the bottom-line results. This theory ties in cohesively with expectancy theory (Vroom, 1964) which attempts to explain how fear-based motivation arises between individuals, suggesting people are motivated to act based on the expectation their actions will result in desired outcomes. As such, employees are at risk of engaging in workplace behaviours aligned with avoiding punishment to satisfy a high BLM supervisor. This leads to individual’s prioritising short-term, tangible outcomes instead of long-term ethical ones, highlighting the adopted transactional mindset that emphasises completing minimum requirements (Quade et al., 2019). ;Quiz <quiz display="simple"> {BLM is only applicable to the workplace} - True + False {BLM always results in engaging unethically or unfavourably} - True + False </quiz> == The Enron Scandal == {{expand}} === Background === [[File:Logo of Enron Corporation (1997).svg|thumb|Figure 5. Enron Corporation]] * The [[w:Enron scandal|Enron scandal]] is a well-known act of company misconduct which perfectly engaged in professionally unethical acts aligning with a BLM. An accounting scandal involving [[w:Enron_Corporation|Enron Corporation]] (see fig. 5), an energy company based in Houston, Texas, which saw key executives identifying accounting loopholes, misusing market-to-market accounting, special purpose entities, and poor financial reporting, ultimately leading to the company hiding billions of dollars in debt from failed projects and deals. The fraudulent activity was revealed after Enron filed for bankruptcy at the end of 2001, where investigations exposed Enron for using off-balance-sheet special purpose entities in order to simultaneously hide debts and inflate profits. Auditors from Arthur Andersen, another accounting firm, were also implicated for shredding documents. This essentially led to one of the largest corporate fraud cases in history. === Bottom-line mentality at Enron Corporation === The Enron corporation set ambitious financial goals, leading to aggressive goal setting, intense pressure and expectations for employees, a picture-perfect environment for a workplace characterised by high BLM. As such, this led to a culture of fear, motivation and competition among employees, and a lack of good leadership. Employees developed a mindset of “doing whatever it takes” (Gibney, 2005) to meet the high sales goals and engaging in unethical acts (e.g., criminal accounting practices) in order to receive large bonuses (Ackman, 2002). Achieving bonuses meant achieving bottom-line attainment, essentially shifting the corporate’s culture to one heavily defined by a BLM. === Consequences and reflection === Enron's fraudulent engagement was eventually exposed which consequently saw one of the biggest corporate bankruptcies in history (see fig. 6). It provides a perfect example of how a BLM can have extreme consequences for a company and its stakeholders. The implications were disastrous - over $60 billion in market value was erased after the company filed for bankruptcy, thousands of people lose{{g}} jobs, pensions, and investments, top executives were convicted of fraud, and new legislation (The Sarbanes-Oxley Act, 2002) was induced to increase financial transparency and corporate accountability. These outcomes highlight the importance of balancing financial goals with ethical consideration, transparency, and long-term perspective. Regardless of the dire outcomes, companies worldwide have fallen victim to a BLM, leading to large-scale scandals. Some of these include WorldCom who engaged in accounting fraud in order to inflate earnings, eventually leading to a massive collapse, and Theranos, who misled investors about its technology, resulting in a prioritisation of growth over truth and transparency. Each case, including the Enron scandal, perfectly illustrates how a BLM can lead to failure on an extreme scale. ==Conclusion== A BLM, while not exclusive to, is most often showcased in an organisational setting. It is a mindset which is characterised by “one dimensional thinking” that focuses entirely on achieving the “bottom line” - goals, standards, or outcomes that an individual or organisation defines as success (Greenbaum et al., 2023). A BLM is often expressed by employees who have a high BLM supervisor, where their LMX relationship results in the subordinate engaging in attitudes and behaviours that align with the leader. Although positive implications exist, such as enhanced organisational performance (Friedman, 2007) and enhanced employee performance (Babalola et al., 2020), these likely do not outweigh the potential negative consequences. Individuals risk engaging in unethical behaviours in the workplace (Mesdaghinia et al., 2019), increased coworker undermining (Greenbaum et al., 2012), and abusive supervisions (Mawrtiz et al., 2017). Theories such as social information processing (Salancik & Pfeffer, 1978) and social exchange theory (Blau, 1964) help explain how interpersonal relationships in the workplace motivate individuals to engage in particular behaviours based on the connections they have with their coworkers and supervisors. [[w:Goal_orientation|Goal orientation theory]] (VandeWalle, 1997) and expectancy theory (Vroom, 1964) identify how individuals’ motivation shifts from intrinsic to extrinsic, and how these behaviours express themselves when people adopt fear-based motivation and work to achieve the bottom-line attainment. Essentially, a BLM motivates individuals to behave in particular ways which may be beneficial short-term, but often overlook longevity and ethical considerations. Examples such as the Enron scandal illustrate this perfectly, also revealing the detrimental consequence that may arise. As such, individuals should be mindful when adopting a BLM. {{RoundBoxTop|theme=10}} '''Key Takeaways''' * The relationship between leader and subordinate helps shape the attitudes, beliefs, and behaviours within the workplace * Adopting a BLM is often beneficial in the short-term, but nearly always is detrimental to the longevity of individuals and the organisation * A BLM is nearly always expressed within the workplace, but can be applicable to other areas of life too {{RoundBoxBottom}} ==See also== * [[Motivation and emotion/Book/2023/Effective leadership|Effective leadership]] (Book chapter, 2023) * [[w:Enron scandal|Enron scandal]] (Wikipedia) * [[w:Enron corporation|Enron corporation]] (Wikipedia) * [[w:Goal orientation|Goal orientation theory]] (Wikipedia) * [[w:leader-member exchange theory|Leader-member exchange]] (Wikipedia) * [[Motivation and emotion/Book/2023/Effective leadership|Leadership and BLM]] (Book chapter, 2023) ==References== {{Hanging indent|1= Ackman D (2002) Pay madness at Enron.

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 [[W:16-cell|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> Notice 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, so we obtain 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, so we obtain 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:Regular_polygon_8_annotated.svg|thumb|Cell-first orthogonal projection of a 16-cell. Only its edges are shown; its long diameter chords are not drawn. None of the 24 edges lie in the view plane.]] 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 has 3 such 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. In this convenient unit-radius 4-coordinate system, the original planar octagon we started with had chords of length: :<math>r_1=\sqrt{2},r_2=\sqrt{2(2+\sqrt{2})} \approx 2.61313,r_3=2+\sqrt{2} \approx 3.41421,r_4=2 \sqrt{2+\sqrt{2}} \approx 3.69552</math> none of which chords occur in a 16-cell or 120-cell except <math>r_1=\sqrt{2}</math>. In the unit-radius 120-cell, the great square edge chord <math>c_{15} = \sqrt{2}</math> occurs in 675 distinct (75 disjoint) 16-cells. 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}} [[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. The two completely orthogonal planes are called invariant rotation planes, because 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 completely orthogonal 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, and takes every vertex to its antipodal vertex 180° degrees away. All the vertices move at once, displaced 180° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. The trajectory of each vertex is a one-eighth segment of its [[W:Geodesic|geodesic]] orbit. Its entire orbit traces a circular helix in 4-space, and also traces a great circle in one of the two completely orthogonal invariant rotation planes, as they tilt sideways into each other's plane. When the isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 180° to its antipodal position, but from the new orientation where the vertex is on the opposite side of the 16-cell departing in the opposite direction. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once, and returns to its original position. == 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 the way we constructed the 16-cell, by skewing a planar octagon's edges so they become edges of the 4-polytope. Because the tesseract has 16 vertices we will need two planar octagons, and to start we must embedded them in 4-space as completely orthogonal planes that intersect at only one point, their common center. Because the tesseract is radially equilateral (unlike the 16-cell), to build a unit-radius tesseract 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 complete square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 180° 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}} tpvhtiwxy1kuclfuh0pp15oujgemcpc 2808069 2808066 2026-05-09T16:11:19Z Dc.samizdat 2856930 /* The 8-point regular polytopes */ 2808069 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 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 [[W:16-cell|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> Notice 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, so we obtain 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, so we obtain 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|Cell-first orthogonal projection of a 16-cell. Only its edges are shown; its long diameter chords are not drawn. None of the 24 edges lie in the view plane.]] 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 has 3 such 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. In this convenient unit-radius 4-coordinate system, the original planar octagon we started with had chords of length: :<math>r_1=\sqrt{2},r_2=\sqrt{2(2+\sqrt{2})} \approx 2.61313,r_3=2+\sqrt{2} \approx 3.41421,r_4=2 \sqrt{2+\sqrt{2}} \approx 3.69552</math> none of which chords occur in a 16-cell or 120-cell except <math>r_1=\sqrt{2}</math>. In the unit-radius 120-cell, the great square edge chord <math>c_{15} = \sqrt{2}</math> occurs in 675 distinct (75 disjoint) 16-cells. 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}} [[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. The two completely orthogonal planes are called invariant rotation planes, because 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 completely orthogonal 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, and takes every vertex to its antipodal vertex 180° degrees away. All the vertices move at once, displaced 180° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. The trajectory of each vertex is a one-eighth segment of its [[W:Geodesic|geodesic]] orbit. Its entire orbit traces a circular helix in 4-space, and also traces a great circle in one of the two completely orthogonal invariant rotation planes, as they tilt sideways into each other's plane. When the isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 180° to its antipodal position, but from the new orientation where the vertex is on the opposite side of the 16-cell departing in the opposite direction. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once, and returns to its original position. == 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 the way we constructed the 16-cell, by skewing a planar octagon's edges so they become edges of the 4-polytope. Because the tesseract has 16 vertices we will need two planar octagons, and to start we must embedded them in 4-space as completely orthogonal planes that intersect at only one point, their common center. Because the tesseract is radially equilateral (unlike the 16-cell), to build a unit-radius tesseract 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 complete square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 180° 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}} 5g0x7vbvsksbriwcj4719c8kvi6bq2h 2808070 2808069 2026-05-09T16:12:58Z Dc.samizdat 2856930 /* The 8-point regular polytopes */ 2808070 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 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 [[W:16-cell|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> Notice 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, so we obtain 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, so we obtain 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|Cell-first orthogonal projection of a regular 16-cell. Only its edges are shown; its long diameter chords are not drawn. All of the 24 edges are the same length and none lie in the view plane.]] 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 has 3 such 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. In this convenient unit-radius 4-coordinate system, the original planar octagon we started with had chords of length: :<math>r_1=\sqrt{2},r_2=\sqrt{2(2+\sqrt{2})} \approx 2.61313,r_3=2+\sqrt{2} \approx 3.41421,r_4=2 \sqrt{2+\sqrt{2}} \approx 3.69552</math> none of which chords occur in a 16-cell or 120-cell except <math>r_1=\sqrt{2}</math>. In the unit-radius 120-cell, the great square edge chord <math>c_{15} = \sqrt{2}</math> occurs in 675 distinct (75 disjoint) 16-cells. 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}} [[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. The two completely orthogonal planes are called invariant rotation planes, because 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 completely orthogonal 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, and takes every vertex to its antipodal vertex 180° degrees away. All the vertices move at once, displaced 180° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. The trajectory of each vertex is a one-eighth segment of its [[W:Geodesic|geodesic]] orbit. Its entire orbit traces a circular helix in 4-space, and also traces a great circle in one of the two completely orthogonal invariant rotation planes, as they tilt sideways into each other's plane. When the isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 180° to its antipodal position, but from the new orientation where the vertex is on the opposite side of the 16-cell departing in the opposite direction. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once, and returns to its original position. == 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 the way we constructed the 16-cell, by skewing a planar octagon's edges so they become edges of the 4-polytope. Because the tesseract has 16 vertices we will need two planar octagons, and to start we must embedded them in 4-space as completely orthogonal planes that intersect at only one point, their common center. Because the tesseract is radially equilateral (unlike the 16-cell), to build a unit-radius tesseract 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 complete square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 180° 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}} pujwx3o8ytx4zpqgbmjn8vxbkbh9ewc 2808071 2808070 2026-05-09T16:17:32Z Dc.samizdat 2856930 /* The 8-point regular polytopes */ 2808071 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 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 [[W:16-cell|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> Notice 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, so we obtain 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, so we obtain 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|Cell-first orthogonal projection of a regular 16-cell. Only its edges are shown; its long diameter chords are not drawn. All of the 24 edges are the same length and none lie in the view plane.]] 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 has 3 such 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. In this convenient unit-radius 4-coordinate system, the original planar octagon we started with had chords of length: :<math>r_1=\sqrt{2},r_2=\sqrt{2(2+\sqrt{2})} \approx 2.61313,r_3=2+\sqrt{2} \approx 3.41421,r_4=2 \sqrt{2+\sqrt{2}} \approx 3.69552</math> none of which chords occur in a 16-cell or 120-cell except <math>r_1=\sqrt{2}</math>. In the unit-radius 120-cell, the great square edge chord <math>c_{15} = \sqrt{2}</math> occurs in 675 distinct (75 disjoint) 16-cells. The vertex coordinates of each 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}} [[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. The two completely orthogonal planes are called invariant rotation planes, because 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 completely orthogonal 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, and takes every vertex to its antipodal vertex 180° degrees away. All the vertices move at once, displaced 180° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. The trajectory of each vertex is a one-eighth segment of its [[W:Geodesic|geodesic]] orbit. Its entire orbit traces a circular helix in 4-space, and also traces a great circle in one of the two completely orthogonal invariant rotation planes, as they tilt sideways into each other's plane. When the isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 180° to its antipodal position, but from the new orientation where the vertex is on the opposite side of the 16-cell departing in the opposite direction. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once, and returns to its original position. == 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 the way we constructed the 16-cell, by skewing a planar octagon's edges so they become edges of the 4-polytope. Because the tesseract has 16 vertices we will need two planar octagons, and to start we must embedded them in 4-space as completely orthogonal planes that intersect at only one point, their common center. Because the tesseract is radially equilateral (unlike the 16-cell), to build a unit-radius tesseract 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 complete square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 180° 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}} iajbhpdlxnbwcyycuwshmektvr6akj6 2808072 2808071 2026-05-09T16:30:53Z Dc.samizdat 2856930 /* The 8-point regular polytopes */ 2808072 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 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 [[W:16-cell|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> Notice 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, so we obtain 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, so we obtain 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|Cell-first orthogonal projection of a regular 16-cell. Only its edges are shown; its long diameter chords are not drawn. All of the 24 edges are the same length and none lie in the view plane.]] 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 has 3 such 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. In this convenient unit-radius 4-coordinate system, the original planar octagon we started with had chords of length: :<math>r_1=\sqrt{2},r_2=\sqrt{2(2+\sqrt{2})} \approx 2.61313,r_3=2+\sqrt{2} \approx 3.41421,r_4=2 \sqrt{2+\sqrt{2}} \approx 3.69552</math> none of which chords occur in a 16-cell or 120-cell except <math>r_1=\sqrt{2}</math>. In the unit-radius 120-cell, the great square edge chord <math>c_{15} = \sqrt{2}</math> occurs in 675 distinct (75 disjoint) 16-cells. The vertex coordinates of each 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}} [[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, and takes every vertex to its antipodal vertex 180° degrees away. All the vertices move at once, displaced 180° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. The trajectory of each vertex is a one-eighth segment of its [[W:Geodesic|geodesic]] orbit. Its entire orbit traces a circular helix in 4-space, and also traces a great circle in one of the two completely orthogonal invariant rotation planes, as they tilt sideways into each other's plane. When the isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 180° to its antipodal position, but from the new orientation where the vertex is on the opposite side of the 16-cell departing in the opposite direction. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once, and returns to its original position. == 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 the way we constructed the 16-cell, by skewing a planar octagon's edges so they become edges of the 4-polytope. Because the tesseract has 16 vertices we will need two planar octagons, and to start we must embedded them in 4-space as completely orthogonal planes that intersect at only one point, their common center. Because the tesseract is radially equilateral (unlike the 16-cell), to build a unit-radius tesseract 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 complete square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 180° 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}} cnfjrbgnlhiv18ei4ljd84sksknrfgo 2808073 2808072 2026-05-09T16:33:11Z Dc.samizdat 2856930 /* The 8-point regular polytopes */ 2808073 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 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 [[W:16-cell|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> Notice 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, so we obtain 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, so we obtain 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|A cell-first orthogonal projection of a regular 16-cell. Only its edges are shown; its long diameter chords are not drawn. All of the 24 edges are the same length and none lie in the view plane.]] 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 has 3 such 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. In this convenient unit-radius 4-coordinate system, the original planar octagon we started with had chords of length: :<math>r_1=\sqrt{2},r_2=\sqrt{2(2+\sqrt{2})} \approx 2.61313,r_3=2+\sqrt{2} \approx 3.41421,r_4=2 \sqrt{2+\sqrt{2}} \approx 3.69552</math> none of which chords occur in a 16-cell or 120-cell except <math>r_1=\sqrt{2}</math>. In the unit-radius 120-cell, the great square edge chord <math>c_{15} = \sqrt{2}</math> occurs in 675 distinct (75 disjoint) 16-cells. The vertex coordinates of each 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}} [[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, and takes every vertex to its antipodal vertex 180° degrees away. All the vertices move at once, displaced 180° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. The trajectory of each vertex is a one-eighth segment of its [[W:Geodesic|geodesic]] orbit. Its entire orbit traces a circular helix in 4-space, and also traces a great circle in one of the two completely orthogonal invariant rotation planes, as they tilt sideways into each other's plane. When the isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 180° to its antipodal position, but from the new orientation where the vertex is on the opposite side of the 16-cell departing in the opposite direction. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once, and returns to its original position. == 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 the way we constructed the 16-cell, by skewing a planar octagon's edges so they become edges of the 4-polytope. Because the tesseract has 16 vertices we will need two planar octagons, and to start we must embedded them in 4-space as completely orthogonal planes that intersect at only one point, their common center. Because the tesseract is radially equilateral (unlike the 16-cell), to build a unit-radius tesseract 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 complete square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 180° 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}} jbcdgdmb6uz3aycyx6yneiou2s552hz 2808074 2808073 2026-05-09T16:53:32Z Dc.samizdat 2856930 /* The 8-point regular polytopes */ 2808074 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 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 [[W:16-cell|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> Notice 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, so we obtain 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, so we obtain 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|A cell-first orthogonal projection of a regular 16-cell. Only its edges are shown; its long diameter chords are not drawn. All of the 24 edges are the same length. Only the edges of two completely orthogonal squares lie in the view plane.]] 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 has 3 such 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. In this convenient unit-radius 4-coordinate system, the original planar octagon we started with had chords of length: :<math>r_1=\sqrt{2},r_2=\sqrt{2(2+\sqrt{2})} \approx 2.61313,r_3=2+\sqrt{2} \approx 3.41421,r_4=2 \sqrt{2+\sqrt{2}} \approx 3.69552</math> none of which chords occur in a 16-cell or 120-cell except <math>r_1=\sqrt{2}</math>. In the unit-radius 120-cell, the great square edge chord <math>c_{15} = \sqrt{2}</math> occurs in 675 distinct (75 disjoint) 16-cells. The vertex coordinates of each 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}} [[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, and takes every vertex to its antipodal vertex 180° degrees away. All the vertices move at once, displaced 180° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. The trajectory of each vertex is a one-eighth segment of its [[W:Geodesic|geodesic]] orbit. Its entire orbit traces a circular helix in 4-space, and also traces a great circle in one of the two completely orthogonal invariant rotation planes, as they tilt sideways into each other's plane. When the isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 180° to its antipodal position, but from the new orientation where the vertex is on the opposite side of the 16-cell departing in the opposite direction. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once, and returns to its original position. == 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 the way we constructed the 16-cell, by skewing a planar octagon's edges so they become edges of the 4-polytope. Because the tesseract has 16 vertices we will need two planar octagons, and to start we must embedded them in 4-space as completely orthogonal planes that intersect at only one point, their common center. Because the tesseract is radially equilateral (unlike the 16-cell), to build a unit-radius tesseract 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 complete square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 180° 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}} 562cvn7wdp4b022q8c88r0af951uw0a 2808075 2808074 2026-05-09T16:59:20Z Dc.samizdat 2856930 /* The 8-point regular polytopes */ 2808075 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 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 [[W:16-cell|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> Notice 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, so we obtain 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, so we obtain 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|A cell-first orthogonal projection of a regular 16-cell. Only its edges are shown; its long diameter chords are not drawn. All of the 24 edges are the same length. Only the edges of two completely orthogonal squares lie parallel to the view plane.]] 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 has 3 such 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. In this convenient unit-radius 4-coordinate system, the original planar octagon we started with had chords of length: :<math>r_1=\sqrt{2},r_2=\sqrt{2(2+\sqrt{2})} \approx 2.61313,r_3=2+\sqrt{2} \approx 3.41421,r_4=2 \sqrt{2+\sqrt{2}} \approx 3.69552</math> none of which chords occur in a 16-cell or 120-cell except <math>r_1=\sqrt{2}</math>. In the unit-radius 120-cell, the great square edge chord <math>c_{15} = \sqrt{2}</math> occurs in 675 distinct (75 disjoint) 16-cells. The vertex coordinates of each 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}} [[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, and takes every vertex to its antipodal vertex 180° degrees away. All the vertices move at once, displaced 180° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. The trajectory of each vertex is a one-eighth segment of its [[W:Geodesic|geodesic]] orbit. Its entire orbit traces a circular helix in 4-space, and also traces a great circle in one of the two completely orthogonal invariant rotation planes, as they tilt sideways into each other's plane. When the isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 180° to its antipodal position, but from the new orientation where the vertex is on the opposite side of the 16-cell departing in the opposite direction. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once, and returns to its original position. == 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 the way we constructed the 16-cell, by skewing a planar octagon's edges so they become edges of the 4-polytope. Because the tesseract has 16 vertices we will need two planar octagons, and to start we must embedded them in 4-space as completely orthogonal planes that intersect at only one point, their common center. Because the tesseract is radially equilateral (unlike the 16-cell), to build a unit-radius tesseract 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 complete square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 180° 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}} fthag4wdmoqm1agu1cevy66dzppq8zr 2808076 2808075 2026-05-09T17:03:39Z Dc.samizdat 2856930 /* The 8-point regular polytopes */ 2808076 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 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 [[W:16-cell|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> Notice 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, so we obtain 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, so we obtain 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|A <small><math>B_4</math></small> orthogonal projection of a regular 16-cell. Only its edges are shown; its long diameter chords are not drawn. All of the 24 edges are the same length. Only the edges of two completely orthogonal squares lie parallel to the view plane.]] 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 has 3 such 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. In this convenient unit-radius 4-coordinate system, the original planar octagon we started with had chords of length: :<math>r_1=\sqrt{2},r_2=\sqrt{2(2+\sqrt{2})} \approx 2.61313,r_3=2+\sqrt{2} \approx 3.41421,r_4=2 \sqrt{2+\sqrt{2}} \approx 3.69552</math> none of which chords occur in a 16-cell or 120-cell except <math>r_1=\sqrt{2}</math>. In the unit-radius 120-cell, the great square edge chord <math>c_{15} = \sqrt{2}</math> occurs in 675 distinct (75 disjoint) 16-cells. The vertex coordinates of each 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}} [[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, and takes every vertex to its antipodal vertex 180° degrees away. All the vertices move at once, displaced 180° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. The trajectory of each vertex is a one-eighth segment of its [[W:Geodesic|geodesic]] orbit. Its entire orbit traces a circular helix in 4-space, and also traces a great circle in one of the two completely orthogonal invariant rotation planes, as they tilt sideways into each other's plane. When the isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 180° to its antipodal position, but from the new orientation where the vertex is on the opposite side of the 16-cell departing in the opposite direction. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once, and returns to its original position. == 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 the way we constructed the 16-cell, by skewing a planar octagon's edges so they become edges of the 4-polytope. Because the tesseract has 16 vertices we will need two planar octagons, and to start we must embedded them in 4-space as completely orthogonal planes that intersect at only one point, their common center. Because the tesseract is radially equilateral (unlike the 16-cell), to build a unit-radius tesseract 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 complete square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 180° 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}} 2wbpiusmz9lhm68b0bop61ecew6thsl 2808077 2808076 2026-05-09T17:04:41Z Dc.samizdat 2856930 /* The 8-point regular polytopes */ 2808077 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 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 [[W:16-cell|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> Notice 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, so we obtain 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, so we obtain 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|A <small><math>\mathrm{B_4}</math></small> orthogonal projection of a regular 16-cell. Only its edges are shown; its long diameter chords are not drawn. All of the 24 edges are the same length. Only the edges of two completely orthogonal squares lie parallel to the view plane.]] 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 has 3 such 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. In this convenient unit-radius 4-coordinate system, the original planar octagon we started with had chords of length: :<math>r_1=\sqrt{2},r_2=\sqrt{2(2+\sqrt{2})} \approx 2.61313,r_3=2+\sqrt{2} \approx 3.41421,r_4=2 \sqrt{2+\sqrt{2}} \approx 3.69552</math> none of which chords occur in a 16-cell or 120-cell except <math>r_1=\sqrt{2}</math>. In the unit-radius 120-cell, the great square edge chord <math>c_{15} = \sqrt{2}</math> occurs in 675 distinct (75 disjoint) 16-cells. The vertex coordinates of each 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}} [[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, and takes every vertex to its antipodal vertex 180° degrees away. All the vertices move at once, displaced 180° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. The trajectory of each vertex is a one-eighth segment of its [[W:Geodesic|geodesic]] orbit. Its entire orbit traces a circular helix in 4-space, and also traces a great circle in one of the two completely orthogonal invariant rotation planes, as they tilt sideways into each other's plane. When the isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 180° to its antipodal position, but from the new orientation where the vertex is on the opposite side of the 16-cell departing in the opposite direction. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once, and returns to its original position. == 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 the way we constructed the 16-cell, by skewing a planar octagon's edges so they become edges of the 4-polytope. Because the tesseract has 16 vertices we will need two planar octagons, and to start we must embedded them in 4-space as completely orthogonal planes that intersect at only one point, their common center. Because the tesseract is radially equilateral (unlike the 16-cell), to build a unit-radius tesseract 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 complete square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 180° 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}} 59wsj75favxid8tauy6hn0tevsspoxr 2808078 2808077 2026-05-09T17:06:35Z Dc.samizdat 2856930 /* The 8-point regular polytopes */ 2808078 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 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 [[W:16-cell|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> Notice 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, so we obtain 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, so we obtain 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|'''B<sub>4</sub>''' orthogonal projection of a regular 16-cell. Only its edges are shown; its long diameter chords are not drawn. All of the 24 edges are the same length. Only the edges of two completely orthogonal squares lie parallel to the view plane.]] 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 has 3 such 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. In this convenient unit-radius 4-coordinate system, the original planar octagon we started with had chords of length: :<math>r_1=\sqrt{2},r_2=\sqrt{2(2+\sqrt{2})} \approx 2.61313,r_3=2+\sqrt{2} \approx 3.41421,r_4=2 \sqrt{2+\sqrt{2}} \approx 3.69552</math> none of which chords occur in a 16-cell or 120-cell except <math>r_1=\sqrt{2}</math>. In the unit-radius 120-cell, the great square edge chord <math>c_{15} = \sqrt{2}</math> occurs in 675 distinct (75 disjoint) 16-cells. The vertex coordinates of each 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}} [[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, and takes every vertex to its antipodal vertex 180° degrees away. All the vertices move at once, displaced 180° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. The trajectory of each vertex is a one-eighth segment of its [[W:Geodesic|geodesic]] orbit. Its entire orbit traces a circular helix in 4-space, and also traces a great circle in one of the two completely orthogonal invariant rotation planes, as they tilt sideways into each other's plane. When the isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 180° to its antipodal position, but from the new orientation where the vertex is on the opposite side of the 16-cell departing in the opposite direction. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once, and returns to its original position. == 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 the way we constructed the 16-cell, by skewing a planar octagon's edges so they become edges of the 4-polytope. Because the tesseract has 16 vertices we will need two planar octagons, and to start we must embedded them in 4-space as completely orthogonal planes that intersect at only one point, their common center. Because the tesseract is radially equilateral (unlike the 16-cell), to build a unit-radius tesseract 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 complete square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 180° 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}} 4t3ll403e39egm8ciu4xl73hq4esnk2 2808079 2808078 2026-05-09T17:07:10Z Dc.samizdat 2856930 /* The 8-point regular polytopes */ 2808079 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 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 [[W:16-cell|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> Notice 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, so we obtain 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, so we obtain 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|B<sub>4</sub> orthogonal projection of a regular 16-cell. Only its edges are shown; its long diameter chords are not drawn. All of the 24 edges are the same length. Only the edges of two completely orthogonal squares lie parallel to the view plane.]] 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 has 3 such 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. In this convenient unit-radius 4-coordinate system, the original planar octagon we started with had chords of length: :<math>r_1=\sqrt{2},r_2=\sqrt{2(2+\sqrt{2})} \approx 2.61313,r_3=2+\sqrt{2} \approx 3.41421,r_4=2 \sqrt{2+\sqrt{2}} \approx 3.69552</math> none of which chords occur in a 16-cell or 120-cell except <math>r_1=\sqrt{2}</math>. In the unit-radius 120-cell, the great square edge chord <math>c_{15} = \sqrt{2}</math> occurs in 675 distinct (75 disjoint) 16-cells. The vertex coordinates of each 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}} [[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, and takes every vertex to its antipodal vertex 180° degrees away. All the vertices move at once, displaced 180° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. The trajectory of each vertex is a one-eighth segment of its [[W:Geodesic|geodesic]] orbit. Its entire orbit traces a circular helix in 4-space, and also traces a great circle in one of the two completely orthogonal invariant rotation planes, as they tilt sideways into each other's plane. When the isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 180° to its antipodal position, but from the new orientation where the vertex is on the opposite side of the 16-cell departing in the opposite direction. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once, and returns to its original position. == 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 the way we constructed the 16-cell, by skewing a planar octagon's edges so they become edges of the 4-polytope. Because the tesseract has 16 vertices we will need two planar octagons, and to start we must embedded them in 4-space as completely orthogonal planes that intersect at only one point, their common center. Because the tesseract is radially equilateral (unlike the 16-cell), to build a unit-radius tesseract 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 complete square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 180° 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}} 3gtxvh31k7m2lxu2m77rqbxiwa0331d 2808080 2808079 2026-05-09T17:08:32Z Dc.samizdat 2856930 /* The 8-point regular polytopes */ 2808080 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 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 [[W:16-cell|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> Notice 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, so we obtain 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, so we obtain 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|[[16-cell#Projections|B<sub>4</sub> orthogonal projection]] of a regular 16-cell. Only its edges are shown; its long diameter chords are not drawn. All of the 24 edges are the same length. Only the edges of two completely orthogonal squares lie parallel to the view plane.]] 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 has 3 such 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. In this convenient unit-radius 4-coordinate system, the original planar octagon we started with had chords of length: :<math>r_1=\sqrt{2},r_2=\sqrt{2(2+\sqrt{2})} \approx 2.61313,r_3=2+\sqrt{2} \approx 3.41421,r_4=2 \sqrt{2+\sqrt{2}} \approx 3.69552</math> none of which chords occur in a 16-cell or 120-cell except <math>r_1=\sqrt{2}</math>. In the unit-radius 120-cell, the great square edge chord <math>c_{15} = \sqrt{2}</math> occurs in 675 distinct (75 disjoint) 16-cells. The vertex coordinates of each 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}} [[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, and takes every vertex to its antipodal vertex 180° degrees away. All the vertices move at once, displaced 180° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. The trajectory of each vertex is a one-eighth segment of its [[W:Geodesic|geodesic]] orbit. Its entire orbit traces a circular helix in 4-space, and also traces a great circle in one of the two completely orthogonal invariant rotation planes, as they tilt sideways into each other's plane. When the isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 180° to its antipodal position, but from the new orientation where the vertex is on the opposite side of the 16-cell departing in the opposite direction. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once, and returns to its original position. == 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 the way we constructed the 16-cell, by skewing a planar octagon's edges so they become edges of the 4-polytope. Because the tesseract has 16 vertices we will need two planar octagons, and to start we must embedded them in 4-space as completely orthogonal planes that intersect at only one point, their common center. Because the tesseract is radially equilateral (unlike the 16-cell), to build a unit-radius tesseract 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 complete square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 180° 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}} 5mp5grnirv9xst86cf2kwllkvygc60u 2808081 2808080 2026-05-09T17:09:33Z Dc.samizdat 2856930 /* The 8-point regular polytopes */ 2808081 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 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 [[W:16-cell|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> Notice 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, so we obtain 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, so we obtain 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|The [[16-cell#Projections|B<sub>4</sub> orthogonal projection]] of a regular 16-cell. Only its edges are shown; its long diameter chords are not drawn. All of the 24 edges are the same length. Only the edges of two completely orthogonal squares lie parallel to the view plane.]] 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 has 3 such 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. In this convenient unit-radius 4-coordinate system, the original planar octagon we started with had chords of length: :<math>r_1=\sqrt{2},r_2=\sqrt{2(2+\sqrt{2})} \approx 2.61313,r_3=2+\sqrt{2} \approx 3.41421,r_4=2 \sqrt{2+\sqrt{2}} \approx 3.69552</math> none of which chords occur in a 16-cell or 120-cell except <math>r_1=\sqrt{2}</math>. In the unit-radius 120-cell, the great square edge chord <math>c_{15} = \sqrt{2}</math> occurs in 675 distinct (75 disjoint) 16-cells. The vertex coordinates of each 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}} [[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, and takes every vertex to its antipodal vertex 180° degrees away. All the vertices move at once, displaced 180° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. The trajectory of each vertex is a one-eighth segment of its [[W:Geodesic|geodesic]] orbit. Its entire orbit traces a circular helix in 4-space, and also traces a great circle in one of the two completely orthogonal invariant rotation planes, as they tilt sideways into each other's plane. When the isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 180° to its antipodal position, but from the new orientation where the vertex is on the opposite side of the 16-cell departing in the opposite direction. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once, and returns to its original position. == 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 the way we constructed the 16-cell, by skewing a planar octagon's edges so they become edges of the 4-polytope. Because the tesseract has 16 vertices we will need two planar octagons, and to start we must embedded them in 4-space as completely orthogonal planes that intersect at only one point, their common center. Because the tesseract is radially equilateral (unlike the 16-cell), to build a unit-radius tesseract 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 complete square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 180° 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}} ii5qubduwj0o1jhk65awcs0ddnf2tuw 2808082 2808081 2026-05-09T17:15:09Z Dc.samizdat 2856930 /* The 8-point regular polytopes */ 2808082 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 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 [[W:16-cell|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> Notice 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, so we obtain 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, so we obtain 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 of the 24 edges are the same length. Only the edges of two completely orthogonal squares lie parallel to the view plane.]] 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 has 3 such 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. In this convenient unit-radius 4-coordinate system, the original planar octagon we started with had chords of length: :<math>r_1=\sqrt{2},r_2=\sqrt{2(2+\sqrt{2})} \approx 2.61313,r_3=2+\sqrt{2} \approx 3.41421,r_4=2 \sqrt{2+\sqrt{2}} \approx 3.69552</math> none of which chords occur in a 16-cell or 120-cell except <math>r_1=\sqrt{2}</math>. In the unit-radius 120-cell, the great square edge chord <math>c_{15} = \sqrt{2}</math> occurs in 675 distinct (75 disjoint) 16-cells. The vertex coordinates of each 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}} [[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, and takes every vertex to its antipodal vertex 180° degrees away. All the vertices move at once, displaced 180° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. The trajectory of each vertex is a one-eighth segment of its [[W:Geodesic|geodesic]] orbit. Its entire orbit traces a circular helix in 4-space, and also traces a great circle in one of the two completely orthogonal invariant rotation planes, as they tilt sideways into each other's plane. When the isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 180° to its antipodal position, but from the new orientation where the vertex is on the opposite side of the 16-cell departing in the opposite direction. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once, and returns to its original position. == 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 the way we constructed the 16-cell, by skewing a planar octagon's edges so they become edges of the 4-polytope. Because the tesseract has 16 vertices we will need two planar octagons, and to start we must embedded them in 4-space as completely orthogonal planes that intersect at only one point, their common center. Because the tesseract is radially equilateral (unlike the 16-cell), to build a unit-radius tesseract 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 complete square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 180° 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}} lrjyra3sj00jr3zmd15206fwjw7g16u 2808083 2808082 2026-05-09T17:15:30Z Dc.samizdat 2856930 /* The 8-point regular polytopes */ 2808083 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 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 [[W:16-cell|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> Notice 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, so we obtain 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, so we obtain 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 of the 24 edges are the same length. Only the edges of two completely orthogonal squares lie parallel to the view plane.]] 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 has 3 such 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. In this convenient unit-radius 4-coordinate system, the original planar octagon we started with had chords of length: :<math>r_1=\sqrt{2},r_2=\sqrt{2(2+\sqrt{2})} \approx 2.61313,r_3=2+\sqrt{2} \approx 3.41421,r_4=2 \sqrt{2+\sqrt{2}} \approx 3.69552</math> none of which chords occur in a 16-cell or 120-cell except <math>r_1=\sqrt{2}</math>. In the unit-radius 120-cell, the great square edge chord <math>c_{15} = \sqrt{2}</math> occurs in 675 distinct (75 disjoint) 16-cells. The vertex coordinates of each 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}} [[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, and takes every vertex to its antipodal vertex 180° degrees away. All the vertices move at once, displaced 180° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. The trajectory of each vertex is a one-eighth segment of its [[W:Geodesic|geodesic]] orbit. Its entire orbit traces a circular helix in 4-space, and also traces a great circle in one of the two completely orthogonal invariant rotation planes, as they tilt sideways into each other's plane. When the isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 180° to its antipodal position, but from the new orientation where the vertex is on the opposite side of the 16-cell departing in the opposite direction. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once, and returns to its original position. == 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 the way we constructed the 16-cell, by skewing a planar octagon's edges so they become edges of the 4-polytope. Because the tesseract has 16 vertices we will need two planar octagons, and to start we must embedded them in 4-space as completely orthogonal planes that intersect at only one point, their common center. Because the tesseract is radially equilateral (unlike the 16-cell), to build a unit-radius tesseract 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 complete square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 180° 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}} nhpm9hvrcqnqy8t16xksnvw7oixsx7r 2808098 2808083 2026-05-09T20:24:40Z Dc.samizdat 2856930 /* The 8-point regular polytopes */ 2808098 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 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 [[W:16-cell|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> Notice 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, so we obtain 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, so we obtain 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 view plane, in completely orthogonal 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 has 3 such 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. In this convenient unit-radius 4-coordinate system, the original planar octagon we started with had chords of length: :<math>r_1=\sqrt{2},r_2=\sqrt{2(2+\sqrt{2})} \approx 2.61313,r_3=2+\sqrt{2} \approx 3.41421,r_4=2 \sqrt{2+\sqrt{2}} \approx 3.69552</math> none of which chords occur in a 16-cell or 120-cell except <math>r_1=\sqrt{2}</math>. In the unit-radius 120-cell, the great square edge chord <math>c_{15} = \sqrt{2}</math> occurs in 675 distinct (75 disjoint) 16-cells. The vertex coordinates of each 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}} [[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, and takes every vertex to its antipodal vertex 180° degrees away. All the vertices move at once, displaced 180° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. The trajectory of each vertex is a one-eighth segment of its [[W:Geodesic|geodesic]] orbit. Its entire orbit traces a circular helix in 4-space, and also traces a great circle in one of the two completely orthogonal invariant rotation planes, as they tilt sideways into each other's plane. When the isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 180° to its antipodal position, but from the new orientation where the vertex is on the opposite side of the 16-cell departing in the opposite direction. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once, and returns to its original position. == 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 the way we constructed the 16-cell, by skewing a planar octagon's edges so they become edges of the 4-polytope. Because the tesseract has 16 vertices we will need two planar octagons, and to start we must embedded them in 4-space as completely orthogonal planes that intersect at only one point, their common center. Because the tesseract is radially equilateral (unlike the 16-cell), to build a unit-radius tesseract 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 complete square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 180° 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}} o26kbruay8who9ier0egp7wcq0wfuxp 2808099 2808098 2026-05-09T20:26:15Z Dc.samizdat 2856930 /* The 8-point regular polytopes */ 2808099 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 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 [[W:16-cell|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> Notice 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, so we obtain 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, so we obtain 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 view 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 has 3 such 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. In this convenient unit-radius 4-coordinate system, the original planar octagon we started with had chords of length: :<math>r_1=\sqrt{2},r_2=\sqrt{2(2+\sqrt{2})} \approx 2.61313,r_3=2+\sqrt{2} \approx 3.41421,r_4=2 \sqrt{2+\sqrt{2}} \approx 3.69552</math> none of which chords occur in a 16-cell or 120-cell except <math>r_1=\sqrt{2}</math>. In the unit-radius 120-cell, the great square edge chord <math>c_{15} = \sqrt{2}</math> occurs in 675 distinct (75 disjoint) 16-cells. The vertex coordinates of each 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}} [[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, and takes every vertex to its antipodal vertex 180° degrees away. All the vertices move at once, displaced 180° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. The trajectory of each vertex is a one-eighth segment of its [[W:Geodesic|geodesic]] orbit. Its entire orbit traces a circular helix in 4-space, and also traces a great circle in one of the two completely orthogonal invariant rotation planes, as they tilt sideways into each other's plane. When the isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 180° to its antipodal position, but from the new orientation where the vertex is on the opposite side of the 16-cell departing in the opposite direction. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once, and returns to its original position. == 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 the way we constructed the 16-cell, by skewing a planar octagon's edges so they become edges of the 4-polytope. Because the tesseract has 16 vertices we will need two planar octagons, and to start we must embedded them in 4-space as completely orthogonal planes that intersect at only one point, their common center. Because the tesseract is radially equilateral (unlike the 16-cell), to build a unit-radius tesseract 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 complete square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 180° 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}} hdxd7gk6dl8cw2eyrtqwzzt3a4wof3x 2808105 2808099 2026-05-09T23:03:23Z Dc.samizdat 2856930 /* The 8-point regular polytopes */ 2808105 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 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 [[W:16-cell|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> Notice 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, so we obtain 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, so we obtain 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 view 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 has 6 such Petrie octagons, which share the same 8 vertices but have distinct 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. In this convenient unit-radius 4-coordinate system, the original planar octagon we started with had chords of length: :<math>r_1=\sqrt{2},r_2=\sqrt{2(2+\sqrt{2})} \approx 2.61313,r_3=2+\sqrt{2} \approx 3.41421,r_4=2 \sqrt{2+\sqrt{2}} \approx 3.69552</math> none of which chords occur in a 16-cell or 120-cell except <math>r_1=\sqrt{2}</math>. In the unit-radius 120-cell, the great square edge chord <math>c_{15} = \sqrt{2}</math> occurs in 675 distinct (75 disjoint) 16-cells. The vertex coordinates of each 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}} [[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, and takes every vertex to its antipodal vertex 180° degrees away. All the vertices move at once, displaced 180° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. The trajectory of each vertex is a one-eighth segment of its [[W:Geodesic|geodesic]] orbit. Its entire orbit traces a circular helix in 4-space, and also traces a great circle in one of the two completely orthogonal invariant rotation planes, as they tilt sideways into each other's plane. When the isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 180° to its antipodal position, but from the new orientation where the vertex is on the opposite side of the 16-cell departing in the opposite direction. In the course of a 720° isoclinic rotation each vertex departs from all 8 vertex positions just once, and returns to its original position. == 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 the way we constructed the 16-cell, by skewing a planar octagon's edges so they become edges of the 4-polytope. Because the tesseract has 16 vertices we will need two planar octagons, and to start we must embedded them in 4-space as completely orthogonal planes that intersect at only one point, their common center. Because the tesseract is radially equilateral (unlike the 16-cell), to build a unit-radius tesseract 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 complete square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 180° 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}} 123et2utdwwzbx52kfp0pd6a7qfu9ll 2808106 2808105 2026-05-09T23:47:20Z Dc.samizdat 2856930 /* The 8-point regular polytopes */ 2808106 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 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 [[W:16-cell|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> Notice 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, so we obtain 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, so we obtain 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 view 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 has 6 such Petrie octagons, which share the same 8 vertices but have distinct 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. In this convenient unit-radius 4-coordinate system, the original planar octagon we started with had chords of length: :<math>r_1=\sqrt{2},r_2=\sqrt{2(2+\sqrt{2})} \approx 2.61313,r_3=2+\sqrt{2} \approx 3.41421,r_4=2 \sqrt{2+\sqrt{2}} \approx 3.69552</math> none of which chords occur in a 16-cell or 120-cell except <math>r_1=\sqrt{2}</math>. In the unit-radius 120-cell, the great square edge chord <math>c_{15} = \sqrt{2}</math> occurs in 675 distinct (75 disjoint) 16-cells. The vertex coordinates of each 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}} [[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. All the vertices move at once on 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 the first displacement. 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 in one of the two completely orthogonal invariant rotation planes as they tilt sideways into each other's plane in the course of a 360° isoclinic rotation. 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 the way we constructed the 16-cell, by skewing a planar octagon's edges so they become edges of the 4-polytope. Because the tesseract has 16 vertices we will need two planar octagons, and to start we must embedded them in 4-space as completely orthogonal planes that intersect at only one point, their common center. Because the tesseract is radially equilateral (unlike the 16-cell), to build a unit-radius tesseract 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 complete square isoclinic revolution, but it is completed in 6 chordal steps of 120° each rather than 8 chordal steps of 180° 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}} 9nncyk00ude3e9y9q4sjpjwlgzgxthu Wikiversity:Candidates for Curatorship 4 327427 2808127 2790002 2026-05-10T03:56:20Z Jtneill 10242 Removed redirect to [[Wikiversity:Candidates for Custodianship#Requests and Nominations for Curatorship]] 2808127 wikitext text/x-wiki {{RoundBoxTop}} {{/Instructions}} {{RoundBoxBottom}} {{process|WV:CC}} {{Wikiversity organization}} __TOC__ == Requests and Nominations for Curatorship == {{shortcut|WV:RFCUR|WV:NFCUR|WV:CC/CUR|WV:CFC/CUR}} ;Notes # Registered users can either request [[Wikiversity:Curators|curatorship]], or be nominated for it by others.

'''The New Way: 100% human generated questions and answers''': If a student/contributor figures out their own questions without the help of an AI/"AI"/LLM please contribute in this section. Otherwise go to "The Old Way" section and contribute there. Questions in no particular order: * Is this "idea" testable? - It is in the plans for it to be testable '''but not testable yet'''. * Is it possible to create one or more hypotheses based on this "idea"? - Multiple hypotheses have been made but never published. Plan is to publish hypotheses related to the "idea" in the future. * Is there a hypothesis or a number of hypotheses related to the idea? ** Can this idea be proven false? - It can not yet be proven false considering a hypothesis is not currently described. Goal is to have a hypothesis at least before June 16, 2026 which is 2 months roughly after the first creation of the page. A basic hypothesis structure may/should exist by then but a complete hypothesis being created that is "perfect in some ways" that can't be predicted yet. '''The Old Way''' This is for any AI/LLM that is available to you. Please document the output here and if you want to contribute the input prompts and more specific details go to the subpage [[Draft:The_Neurodiversity-inspired_Idea/AI_Prompt_History_for_Questions]] Questions and 'follow up'-/improved questions generated by Google "AI Mode": * What is missing right now? ** "Improved" version: "What key sections are missing from this research draft to meet Wikiversity standards?" * How will we know if the idea is working? == Naming Suggestions == Feel free to edit/modify or remove content in this section. Example name ideas: * Pre-research: Observations made inside psychiatry spectrums * Psychiatric Spectrum Specifications ''These names should probably not be used but were kept for inspiring questions in readers'': * Next-Gen Brain Types * Next-Gen Sociology * Next-Gen Neurotypes == Potential best-case uses of "idea" if fully developed == This section is for expected best-case uses for the "idea" if fully developed. Probably best to keep this section short. Assumptions may develop from it otherwise. Maybe max 5 items? * Could assist in better matchmaking in relationships where "compatibility"/"rapport" is important. * Better matchmaking in romantic relationships. == References/in-Wikiversity-Wikilinks == This section is for linking to specific references: * [2] - [[Draft:The_Neurodiversity-inspired_Idea/AI_Prompt_History_for_Questions#Reference_2]] == Future references to this draft == In the event that other publications start referring to this draft in the future, the template "findsources" is added: {{findsources}} aljqoatpqxpzrunyskgx7yhenz2p98v Draft:The Neurodiversity-inspired Idea/AI Prompt History for Questions 118 329180 2808115 2806803 2026-05-10T01:18:37Z ThinkingScience 3061446 /* "Reference Coding" */ requested AI response at 50 words max. Tom Hanks is the 2nd person suggested by AI Mode 2808115 wikitext text/x-wiki {{AI-generated}} For practical purposes we can assume that everything on this page is "AI-generated". Where it is not, it will be stated. How questions were generated appear on this page for transparency reasons. The input and output questions are documented. This is a page where one can get a question and then work further to refine the question. This is some disorganized inputs and outputs. Inputs are sent to an AI/LLM and outputs is about what the AI/LLM gives the user. When it says "'''human output'''" that means that a user thought of a question based on an AI's/LLM's question. Simply a follow-up question to an AI's/LLM's question. == "AI Mode" by Google inputs/outputs == News: In this section today at April 27, 2026 a new 'data point'/method for noting down multiple inputs which were typed before without the output as the previous output may be ignored because only the latest output may be interesting for the user. We call this: * "pre-input" - "pre-input" are inputs that were sent before the main input where we also provide the output. The pre-inputs don't need their own outputs as that adds too much complexity and we try to avoid spamming Wikiversity. Please feel free to add subsections here. * human input April 18, 2026: I have an idea and I'm developing the idea here on English Wikiversity: Draft:The Neurodiversity-inspired Idea. What kind of questions might I need to move forward. I'm looking for academic feedback. The problem is "people don't understand themselves" and have to go through "dragged-out diagnosis processes" by psychiatrists. The problem to be solved: how the brain works and presenting a system how it can be mapped. ** output Purpose: "What specific problem does this idea solve for the reader?" ** output Reach: "Who is the primary 'student' for this draft?" *** human output: Who is the target audience for this draft? ** output Validation: "What existing research or lived experience supports this claim?" ** output Interactivity: "What can a reader do with this information right now?" * human input: Is a "neurotype" up for debate? Does every researcher have their own definition of what a "neurotype" is? Based on this input can you suggest better questhe tions? === Creating a hypothesis === Misspellings have been kept. Don't correct misspellings in inputs or outputs. Misspellings are data. * pre inputs by human to "AI Mode" on April 27, 2026 ** operationalization (Q286017) describes itself on Wikidata as: "process of defining the measurement of a phenomenon that is not directly measurable, though its existence is indicated by other phenomena" What does that mean in 20 words max? ** what is operationalization for ie. a hypothesis about whether sunlight is good for plants or not? ** I operationalization a scientific concept and is it available on wikiversity? ** Can a hypothesis be created for this project? https://en.wikiversity.org/wiki/Draft:The_Neurodiversity-inspired_Idea#%22Research_projects_must_fully_document_the_methods%22 ** neurodiversity-inspired is not the same thing as neurodiversity-based ** bro you are lost in the neurodiversity mumbo jumbo ** Let's just agree on one thing: If I don't tell you what I'm thinking, you won't know? Correct? ** so that's why I should provide some input, but question is when? ** What do you mean now? Now now or now?(joke) ** Whenever I am ready. That's well explained! I am not yet ready so while I'm not ready please don't blather like a...like a... ** When I'm ready I'll telll you, then you'll respond and then I will send you my idea, ok? ** I'm not ready yet. My hypothesis or hypotheses are measuring rapport between individuals. For the hypothesis I need to state how rapport will be measured. * human input to same "AI Mode" on April 27, 2026: So the individuals that participate in the 'sociological' hypothesis experiment will interact through the tool known as "Etherpad". ** "AI Mode" output same date: {{quote|That is a great choice for a study because Etherpad produces a literal "paper trail" of the interaction. Since it's a collaborative text editor, you can track rapport through the digital footprint of how people type together. When you are ready to send your full idea, we can look at measuring rapport in Etherpad through things like: * Synchronicity: How often they type at the exact same time. * Editing behavior: Do they delete each other's work or build upon it? * Chat usage: How much they use the side-bar chat versus the main document. I'll keep it brief as requested. Standing by for your signal.}} === Methodology questions === * human input April 20, 2026: On Wikiversity they say "ask the right questions with your idea". I got an idea, this is my idea: "The Neurodiversity-inspired idea". My methodology is about watching videos of famous people but I want to do the public notes in a way that doesn't "offend the famous people" when I compare them with other famous people. ** output: "How does this person's way of processing information differ from or similar to the other person in this comparison?", "What strengths or 'superpowers' are evident in how they navigate this specific situation?". Strategy for Non-Offensive Public Notes. Focus on Behaviours, Not Diagnoses: Only comment on observed actions or statements. Use phrases like, "Their speaking style is consistent with..." rather than "They are...". '''Methodology questions''' When watching a famous person in a video interview in the current "methodology": * How does this person's way of processing information differ to another person in this comparison? (modified by a human) * What strengths or 'superpowers' are evident in how they navigate this specific situation? ==== Failures in output we can learn from in Methodology questions to AIs/LLMs ==== It's not always easy to find the right questions. When the question has some problems that causes an output that doesn't make sense they can be put in this section. * human input April 19, 2026: I'm looking for an English-Wikiversity-compliant methodology to study famous people in video interviews while "being allowed" to group them together without it being "heresy" in scientific communities. Can you formulate that as a question? ** output "didn't make sense" / "was irrelevant" (conclusion by human contributor) == "Reference Coding" == '''⚠️⚠️⚠️ WARNING ⚠️⚠️⚠️: Very important. This section's name should not be changed because other pages already link here and if the section's name is changed those links will break! For any questions please use the talk page.''' Here happens a "reference coding" so it's easy to find an input when it is being referenced from another page on Wikiversity. ie. [1] should be the same as [1] on another page which is referencing the [1] here. These inputs/outputs were done with "AI Mode" by Google. * Reference [1] * human input April 22: I need somebody who is a famous person and that we can tie to the word "draft" even indirectly and that is a modern person and that appears in many different video interviews. ** output: A compelling modern person for your "Method development" section is Taylor Swift. She is a modern icon who appears in countless video interviews and can be tied directly to the word "draft" through her creative process and public statements. === Reference 2 === Making an own Wiki-section is what might work better. * human input to "AI Mode" on April 27, 2026: So the individuals that participate in the 'sociological' hypothesis experiment will interact through the tool known as "Etherpad". ** "AI Mode" output same date: {{quote|That is a great choice for a study because Etherpad produces a literal "paper trail" of the interaction.

Standing by for your signal.}} === Reference 3 === Method is being developed as this is written...this is the 2nd person being added to "the idea". * Human input May 10, 2026: Answer in English. I need you to suggest somebody who is a modern famous and public person and that appears in many different video interviews, that we can less or more 'loosely' associate with the word "The" which is the 2nd word in draft project based on this URL https://en.wikiversity.org/wiki/Draft:The_Neurodiversity-inspired_Idea/Method_development_through_video_notes. The previous person that was chosen was Taylor Swift. Please select somebody who can be compared in a "Do no harm" way. If the person is somebody Taylor Swift has feuded with please don't suggest them! Answer max 50 words. ** "AI Mode" output same date: {{quote|Tom Hanks is a great choice. He is often called "The" quintessential nice guy or "The American Dad." Like Taylor Swift, he is a massive, clean-cut public figure with endless video interviews. He avoids controversy and fits a "do no harm" philosophy perfectly. Would you like to explore Tom Hanks' specific interviews for your project?}} sgols475dvghbogi349yrquf4n6n8jf Draft:The Neurodiversity-inspired Idea/Method development through video notes 118 329210 2808113 2805922 2026-05-10T00:46:06Z ThinkingScience 3061446 /* Choosing video material */ I came up with this idea today about how to ensure "Do no harm" is followed. No comparison ever between feuding people 2808113 wikitext text/x-wiki {{AI-generated}} == What {{tl|AI-generated}} means on this page == It means that the content on this page may be generated in the future.

If any content is generated contributors are encouraged to edit this section and make the appropriate changes to let students know that there has been a change. What it means for now is that the contributors to this page are encouraged to interact with an "AI"/LLM in regards to * decision-making on what to focus on next that this page may need * brainstorming with the "AI program" of their choice regarding what to contribute next * ask "AI program" for advice on how to contribute video notes in a [[Wikiversity:Research ethics]]-way and a "Do no harm"/"Primum non nocere" way. == Original Intent == The intent for this page is for it to be used to develop a 'method' for working with "materials" like video interviews of famous people or video interviews/content of volunteers who sign up for [[Draft:The Neurodiversity-inspired Idea]]. == Contributor/Student Questions == If a contributor doesn't feel to edit this page directly but the contributor/student wants to ask a question to encourage development or they have any other question, this section is for that.

The way one makes video notes on this page may set the example for the method that will be developed in the future. Goal is to treat famous people like any other people: like human beings. How one expresses oneself is very important and the original creator of this page may not be the best in that area, thus '''feel free to be bold and edit this page'''.

This idea may be lacking but one starts making mistakes, then later we learn how to do it better and then we fix those mistakes. == Choosing video material == Video notes can wait. Let's focus first on choosing video material. Why can video notes wait? The first task is choosing the video material and explaining why the specific material was chosen. It may not always be easy to take a decision and ie. ChatGPT or "AI Mode" can sometimes be used to make it easier to just choose something so one can focus on work and less on decisions. For some students/contributors that may be helpful. The video notes though may be done step by step, one chooses a video material, explains the reasoning behind it and then focuses on working on the video notes in a "Do no harm" manner. * How to associate the first person we focus on regarding the word ''draft''? Using "AI Mode" by Google on April 22, 2026, as a way to make "decisions easier" this input helped this project moving forward(feedback/comments appreciated) with the first "choice": ** Taylor Swift[1] Taylor Swift is associated with the word ''draft'' in that she has been open in videos about her music creation process. That makes this project focus on Taylor Swift. === Responsibility in regards to choosing video material === In this section if you feel free like listing yourself feel free to. Adhering to "Do no harm" can be very challenging. Though we have to try our best to achieve this. It may be good or even necessary to explain why a choice was made so that anyone joining this project can be sure that there was a 100% human judgement made when choosing a subject. As this project deals with real human beings similar to how psychiatry deals with real human beings with ie. the Autism Spectrum, the Bipolar Spectrum and similar were chosen and worked on, it dealt with real people. Psychiatry though dealt/deal mainly with children and this project deals mainly with adults. Preferably adults whose brains have fully matured and who have lived a few years with a fully matured brain which may mean 29 years of age which may be a good minimum age for this project. This is a section where a user who is a contributor would like to take responsibility for a choice: * [[User:ThinkingScience]]. I hereby take responsibility for the following choices: Taylor Swift. Read on my user page more at [[User:ThinkingScience#T]] why I made this choice. * Example user 2 === People chosen === Do no harm will be challenging but is a requirement. Video notes must be respectful and not harm the individual. '''For that to be achieved if two or more individuals are compared they must not have been in a feud or in a conflict with each other'''. '''If they weren't in a feud and they are in the future, the notes of the most recent version must be removed/modified regarding any comparisons of currently feuding individuals.'''

How one expresses oneself is very important and the original creator of this page may not be the best in that area, thus '''feel free to be bold and edit this page'''. The start is usually the hardest and based on the idea name one can focus on any famous person related to the words * draft * neurodiversity * inspiration * idea This is how this start is made. This idea may be lacking but one starts making mistakes, then later we learn how to do it better and then we fix those mistakes. == Choosing video material == Video notes can wait. Let's focus first on choosing video material. Why can video notes wait? The first task is choosing the video material and explaining why the specific material was chosen. It may not always be easy to take a decision and ie. ChatGPT or "AI Mode" can sometimes be used to make it easier to just choose something so one can focus on work and less on decisions. For some students/contributors that may be helpful. The video notes though may be done step by step, one chooses a video material, explains the reasoning behind it and then focuses on working on the video notes in a "Do no harm" manner. * How to associate the first person we focus on regarding the word ''draft''? Using "AI Mode" by Google on April 22, 2026, as a way to make "decisions easier" this input helped this project moving forward(feedback/comments appreciated) with the first "choice": ** Taylor Swift[1] * Tom Hanks[2] Taylor Swift is associated with the word ''draft'' in that she has been open in videos about her music creation process. That makes this project focus on Taylor Swift as 1st person being added regarding 'video notes'. === Responsibility in regards to choosing video material === In this section if you feel free like listing yourself feel free to. Adhering to "Do no harm" can be very challenging. Though we have to try our best to achieve this. It may be good or even necessary to explain why a choice was made so that anyone joining this project can be sure that there was a 100% human judgement made when choosing a subject. As this project deals with real human beings similar to how psychiatry deals with real human beings with ie. the Autism Spectrum, the Bipolar Spectrum and similar were chosen and worked on, it dealt with real people. Psychiatry though dealt/deal mainly with children and this project deals mainly with adults. Preferably adults whose brains have fully matured and who have lived a few years with a fully matured brain which may mean 29 years of age which may be a good minimum age for this project. This is a section where a user who is a contributor would like to take responsibility for a choice: * [[User:ThinkingScience]]. I hereby take responsibility for the following choices: Taylor Swift. Read on my user page more at [[User:ThinkingScience#T]] why I made this choice. ** [[User:ThinkingScience#Tom_Hanks]] 2nd person I chose. * Example user choice 2 * Example user choice 3 * Example user choice 4 * Example user choice 5 === People chosen === Do no harm will be challenging but is a requirement. Video notes must be respectful and not harm the individual. '''For that to be achieved if two or more individuals are compared they must not have been in a feud or in a conflict with each other'''. '''If they weren't in a feud and they are in the future, the notes of the most recent version must be removed/modified regarding any comparisons of currently feuding individuals.''' This must be done to ensure the "Do no harm" requirement is met for this project. * Taylor Swift[1] == How the Linking References System works == ie. [1], [2] etc. This section may be superfluous once a better system has replaced this. Purpose: teach the students/contributors how to link to a central place where human generated inputs are made and "AI-generated" outputs results are made. When you see ie. a [1] that means that you can find that [1] input made by a human and output most probably made by a an "AI program" or Large Language Model here if you look hard enough. Otherwise please submit feedback for how the user experience was.

Previously, she was Vice President at the [[w:Anti-Defamation League|Anti-Defamation League]] (ADL) Center for Technology & Society (CTS). She was a [[w:Facebook|Facebook]] election integrity head in 2018 and later became a whistleblower, speaking publicly about the dangers to democracy stemming from the company's decisions and products. She has held other other positions protecting democracy including as an intelligence officer, diplomat, and White House advisor. C4D contributed to the recent March 24, 2026, jury verdict in a civil case against Internet companies in [[w:New Mexico|New Mexico]].<ref name=NM>McQue (2026), <!--C4D and the Courts: Meta Guilty Verdicts-->{{cite Q|Q139572464}}</ref> Eisenstat is interviewed by Spencer Graves.<ref name=Graves><!--Spencer Graves-->{{cite Q|Q56452480}}</ref> == Eisenstat's work == Eisenstat's work includes a [[w:TED (conference)|TED Talk]] and an [[w:South by Southwest|SXSW panel]] in 2020 and a 2024 research report on tech platforms and political violence. === 2020 TED talk === In Eisenstat's (2020) TED talk, she said that around 2015 she began to notice that she was losing the ability to engage with others who were thought differently. 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 and 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 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 current literature aims to shed light on a neglected niche of suicide research: autobiographical memory. Despite the overwhelming research suggesting correlations between OGM and depression and suicidal ideation, research has not thoroughly explored OGM's exact role in a cognitive, theoretical framework of suicidal ideation (specifically within the IMV model). By conducting a narrative review and integrating research on OGM's role in suicidal ideation, this paper furthers understanding on OGM's role in suicidal ideation. ==OGM as Vulnerability== Evidence suggests that OGM is a cognitive vulnerability associated with depression and suicidal ideation, though its predictive relevance may vary depending on the population. A meta analysis performed by Sumner et. al (2010) found that OGM accounted for about 1-2% of the variance in depressive symptoms at follow-up<ref name=":2" />. A 2020 study found that OGM was associated with depressed patients' current suicidal ideation state and worse-point suicidal ideation, while OGM affected the healthy patients' worse-point suicidal ideation<ref name=":2" />. However, Crane et. al (2016) conducted a longitudinal study of n≈5800 adolescents from ages 13 to 16 and found that OGM was not significantly associated with depression and did not moderate the effect of life events, suggesting OGM may not be as generalizable to community samples vs. high-risk populations<ref name=":2" />. Even though the findings indicated that OGM was not significantly associated with depression, the study highlights that OGM may function as a vulnerability within high-risk populations. This suggests that OGM's predictive relevance may depend on the risk-level of the population. OGM persists even past depression, as found in Hallford et. al (2022). A meta-analysis indicated that participants with remitted depression continue to experience small to moderate deficiencies in being able to recall "specific, event-level personal memories". This indicates that OGM isn't merely a symptom of depression, but may function as a risk factor for future depressive episodes<ref name=":2" />. Considering the above, the analysis suggests that OGM may function as a cognitive vulnerability that is further exacerbated in high-risk populations vs. the general population. ==Mechanisms== {{Notice|Structure #Specific memories help problem solving, OGM impairs this #OGM makes ppl brood/traps 'em in brooding or rummination #Tie to IMV model + suicidal ideation formation}} The inability to retrieve specific memories from one's autobiographical memory may lead to inefficient problem-solving abilities, which can impact one's ability to deal with difficult situations as they lack historical experience to rely on<ref name=":2" /><ref>{{Cite journal|last=Arie|first=Miri|last2=Apter|first2=Alan|last3=Orbach|first3=Israel|last4=Yefet|first4=Yael|last5=Zalzman|first5=Gil|date=2008-01-01|title=Autobiographical memory, interpersonal problem solving, and suicidal behavior in adolescent inpatients|url=https://www.sciencedirect.com/science/article/pii/S0010440X07000922|journal=Comprehensive Psychiatry|volume=49|issue=1|pages=22–29|doi=10.1016/j.comppsych.2007.07.004|issn=0010-440X}}</ref>.

The motivational phase is characterized by suicidal ideation formation, where feelings of entrapment (described as a "proximal [predictor] of suicidal ideation"<ref>{{Cite journal|last=O'Connor|first=Rory C.|last2=Kirtley|first2=Olivia J.|date=2018-09-05|title=The integrated motivational-volitional model of suicidal behaviour|url=https://pmc.ncbi.nlm.nih.gov/articles/PMC6053985/|journal=Philosophical Transactions of the Royal Society of London.

The current literature aims to shed light on a neglected niche of suicide research: autobiographical memory. Despite the overwhelming research suggesting correlations between OGM and depression and suicidal ideation, research has not thoroughly explored OGM's exact role in a cognitive, theoretical framework of suicidal ideation (specifically within the IMV model). By conducting a narrative review and integrating research on OGM's role in suicidal ideation, this paper furthers understanding on OGM's role in suicidal ideation. ==OGM as Vulnerability== Evidence suggests that OGM is a cognitive vulnerability associated with depression and suicidal ideation, though its predictive relevance may vary depending on the population. A meta analysis performed by Sumner et. al (2010) found that OGM accounted for about 1-2% of the variance in depressive symptoms at follow-up<ref name=":2" />. A 2020 study found that OGM was associated with depressed patients' current suicidal ideation state and worse-point suicidal ideation, while OGM affected the healthy patients' worse-point suicidal ideation<ref name=":2" />. However, Crane et. al (2016) conducted a longitudinal study of n≈5800 adolescents from ages 13 to 16 and found that OGM was not significantly associated with depression and did not moderate the effect of life events, suggesting OGM may not be as generalizable to community samples vs. high-risk populations<ref name=":2" />. Even though the findings indicated that OGM was not significantly associated with depression, the study highlights that OGM may function as a vulnerability within high-risk populations. This suggests that OGM's predictive relevance may depend on the risk-level of the population. OGM persists even past depression, as found in Hallford et. al (2022). A meta-analysis indicated that participants with remitted depression continue to experience small to moderate deficiencies in being able to recall "specific, event-level personal memories". This indicates that OGM isn't merely a symptom of depression, but may function as a risk factor for future depressive episodes<ref name=":2" />. Considering the above, the analysis suggests that OGM may function as a cognitive vulnerability that is further exacerbated in high-risk populations vs. the general population. ==Mechanisms== The inability to retrieve specific memories from one's autobiographical memory may lead to inefficient problem-solving abilities, which can impact one's ability to deal with difficult situations as they lack past experiences to rely on<ref name=":2" /><ref>{{Cite journal|last=Arie|first=Miri|last2=Apter|first2=Alan|last3=Orbach|first3=Israel|last4=Yefet|first4=Yael|last5=Zalzman|first5=Gil|date=2008-01-01|title=Autobiographical memory, interpersonal problem solving, and suicidal behavior in adolescent inpatients|url=https://www.sciencedirect.com/science/article/pii/S0010440X07000922|journal=Comprehensive Psychiatry|volume=49|issue=1|pages=22–29|doi=10.1016/j.comppsych.2007.07.004|issn=0010-440X}}</ref>.

In a [[wiki]], trust arises from good editing of webpages and "good editing" is what advances the project. If you have a record of good editing then you are likely to be trusted and be granted the tools to protect pages from vandalism and block vandals and delete useless pages. Having those tools really just means you have to do more work - dull and boring work - for the community.
