But this is contrary to the goals of Wikiversity, and I'm not sure it's a good idea, even with regard to WMF. If WMF decides to close a project and another community lets it run on its domain, that's a bit of an undermining of WMF's and the community's decisions. Given that Wikiversity has had several conflicts with other communities and WMF in its history, I'm against it.--[[User:Juandev|Juandev]] ([[User talk:Juandev|discuss]] • [[Special:Contributions/Juandev|contribs]]) 18:59, 15 May 2026 (UTC) *{{contra}} This seems like a proposal to continue the mission of WikiNews, but not a proposal specifically to improve Wikiversity.

It was already suggested, rather bafflingly, that Wikinews parasitize Wikipedia as a host. If it were allowed to freeload off of Wikiversity it would simply promote a view I and likely many others have— that Wikiversity (as it currently exists) has no standards and mostly just exists to host subpar content that wouldn’t be tolerated on any other Wikimedia site. Wikinews needs a new, non-Wikimedia host, and Wikiversity needs to get its act together by enforcing a minimum scope and standard for what it allows. --[[User:Dronebogus|Dronebogus]] ([[User talk:Dronebogus|discuss]] • [[Special:Contributions/Dronebogus|contribs]]) 01:16, 4 June 2026 (UTC) * {{oppose}} per above.

In 2021 I officially initiated a podcast series on "Media & Democracy" syndicated for the [[w:List of Pacifica Radio stations and affiliates|Pacifica radio network]]. In 2024 I converted it from irregular to fortnightly. I think this is all educational and supports the Wikiversity education mission, and I think that "rehost Wikinews here" would be appropriate. (I had some experience with Wikinews a few years ago. I felt it was too tightly controlled: Article submissions went stale, because I could not get official permission to publish and I could not get the information needed to understand what I was supposed to do to obtain the official permission. I would be opposed to rehosting Wikinews here if the policy similarly made it unreasonably difficult for volunteer contributor to get the information needed to meet the journalistic standards imposed by the overworked editors.) {{unsigned|DavidMCEddy}} ===Comments and questions=== :Definitely worthy of discussion, so I have no problem with the proposal in the sitenotice. :Initial questions: :* Does this proposal include importing English Wikinews content e.g., to [[Wikinews]] subpages? :* What are "active editions"? :* How can Wikiversity navigate the concerns that lead to the closure of Wikinews? :* Are any changes to the scope of Wikinews proposed? :* How does [[Wikinews]] fit with the [[Wikiversity:Mission]]?

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

I referenced it earlier, but to be explicit, there is a [[:m:Proposal for Closing Wikinews|report by a task force on sister projects]] that outlines their concerns. There are a few, one of which was the nature of the staleness of news.

Challenges of Wikinews included that it required timely reporting and fact-checking processes which differed greatly from the well-established ones in Wikipedia. Here in Wikiversity, there is the WikiJournal project, and that can take some some forms of journalism, just not breaking news reporting. I am in favor of salvaging parts of Wikinews if helpful. Could it, would it be feasible to adapt Wikijournal to accept some forms of news journalism, but just not the timed news reporting? For example, WikiJournal already is doing conference proceedings, and could likely do related event reports even months after the event ended. It could probably accept long-form investigative reporting, which is a sort of news that is not breaking news. I am not sure what the possibilities are, but I would prefer to build up systems that already work rather than import systems which had problems elsewhere. Thanks.

Therefore, to maintain consistency with [[Wikiversity:Curatorship#How does one become a curator?]], I propose that we repeal the probationary custodianship process and change it more or less to align with the curatorship process, effectively making probationary custodians permanent ones. However, custodian mentors would still be retained. Thoughts? [[User:Codename Noreste|Codename Noreste]] ([[User talk:Codename Noreste|discuss]] • [[Special:Contributions/Codename Noreste|contribs]]) 17:55, 5 June 2026 (UTC) :#Yes, I agree. :#Thats a good point, but I dont know. At least I dont think its a good idea that both groups i.e. crats and custodiants can do that, it may create chaos. :#Another good point. It seems to me that the current situation is somewhat unclear and should be clarified. I understand the original status of [[Wikiversity:Probationary custodians|Probationary custodians]] as a historicall and invalid, but at the same time I consider myself a probationary custodian, because on the Wikiversity:Custodianship page in the ''[[Wikiversity:Custodianship#How does one become a custodian?|How does one become a custodian?]]'' section it says, I quote, ''"II ...then you will be approved as a probationary custodian for a period of at least four weeks"''. :::Mentors should definitely be kept, but for certain applicants the probation and mentorship should be abolished. For example, if someone was an active custodian for 5 years, then loses their rights or gives them up for a year and then wants to resume their custodial activities, there is no reason for them to undergo a training period. It burdens both the mentors and the community with double voting. The only exception could be a situation where policies or tools for custodians change significantly during that year, or the candidate wants to. :[[User:Juandev|Juandev]] ([[User talk:Juandev|discuss]] • [[Special:Contributions/Juandev|contribs]]) 06:08, 9 June 2026 (UTC) == New user what do I do here == I love wikipedia and the wikiversity project seems super interesting.

I've left a welcome message on your talk page so that should provide you a plethora of useful links for you to look at so you can familiarize yourself with the project.

In addition, today we also have some global policies that prohibit, for example, attacks on members of the Wikimedia movement or undermining other projects. However, at the very beginning, I would start by collecting your opinions. What content or what research should not be allowed on Wikiversity? [[User:Juandev|Juandev]] ([[User talk:Juandev|discuss]] • [[Special:Contributions/Juandev|contribs]]) 05:52, 9 June 2026 (UTC) :One ethical issue that I think should be non-controversial is related to good faith in the learning modules. So, learning materials should not be hoaxes or encourage behavior or methods that don't work or that misrepresent the facts or the likelihood of something occurring, etc. and authors should also not plagiarize or misrepresent authorship, etc. That was quite a run-on, but I hope that others can tease out what I mean here. ―[[User:Koavf|Justin (<span style="color:grey">ko'''a'''<span style="color:black">v</span>f</span>)]]<span style="color:red">❤[[User talk:Koavf|T]]☮[[Special:Contributions/Koavf|C]]☺[[Special:Emailuser/Koavf|M]]☯</span> 07:39, 9 June 2026 (UTC) ::I look at it from a practical perspective. We can give that to the policy, but I see the problem in that we are not able to check it except plagiarism. ::Plagiarism can be partially detected during patrolling. I see a new text, I put part of it in Google and I check if it is copied from the web. It is a problem with copying from books or other offline sources, but sometimes it happens that someone finds out that something is copied from somewhere and it can be deleted. ::The biggest issue we have here is that we are missing Wikipedia's control mechanism: references. Only some types of resources on Wikiversity require references. In-line references are not often used in courses, exercises, lectures, etc. We are thus deprived of one of the excellent control mechanisms and the only option is for the increase in the number of members with various qualifications to check it for their colleagues.

The American Colonists and the British Parliament disagreed over how the colonies should be governed or "controlled". The British Parliament believed they had the legal authority to govern the colonists, but the colonists thought they should not be governed by the British due to having no representation in Parliament. The new laws created by the British Parliament aggravated the Colonists. ===== Virginians ===== Virginians participated in events leading to war with Great Britain with the appointment of Thomas Jefferson to write the famous '''Declaration of Independence''' The Declaration of Independence gave some simple ideas on which a government should be based. It also gave reasons why the American Colonists should become independent from the British. The Declaration of Independence stated that: <big>''Authority to govern belonged to the people rather than to kings, that all people were created equal, and had rights to life, liberty and the pursuit of happiness.''</big> On July 4, 1776 - Delegates of the Second Continental Congress met in Philadelphia and adopted the Declaration of Independence. === People === '''James A. Lafayette''' - From New Kent County, was one of many enslaved Africans from Virginia who served the troops of the Continental Army. After the war, the General Assembly acknowledged his support and granted his freedom. '''George Washington''' - Provided military leadership by serving in the Continental Army as the Commander-in-Chief. He also was a presidents inspire in as president. '''Patrick Henry''' - Was the famous patriot who gave his ''"Give me liberty or give me death"'' speech in St. John's Church in Richmond, Virginia. '''Thomas Jefferson''' - Was the writer of the ''"Declaration of Independence"'' and the 3rd President of the United States (1801-1809). '''Jack Jouett''' - Was the famous captain of the Virginia Militia and best known from mounting his horse and riding to the General Assembly through the 40-mile forest through Charlottesville in 1781 because the British were going to the General Assembly to kill all who attended. Jouett's prize was silver-mounted pistols and a jewel sword. === Battles === '''Terms to Know''' * Minutemen - soldiers who pledged to be ready to fight at a minute's notice. ===== Battle of Lexington and Concord ===== The Battle of Lexington and Concord took place in April 1775 in Massachusetts and were the first battles of the American Revolution. The British were not able to catch the minutemen's supplies or Sam Adams/John Hancock, who were alerted of the arriving British by Paul Revere. This was the beginning of the conflict. ===== Battle of Great Bridge ===== The Battle of Great Bridge took place around seven miles south of Norfolk in December 1775. The road leading from North Carolina to Norfolk, Virginia. A village started here at this point known as the Great Bridge. Although the battle was a brief battle lasting only 30 minutes, it brought destruction to Norfolk, Virginia. The Colonists victory was a major step in eliminating British lines and they let the British Governor flee from Norfolk. ===== Battle of Yorktown ===== The city of Yorktown was located on a peninsula and there is a river in Yorktown known simply as the '''Yorktown River'''. The Battle took place in Yorktown in 1781, this battle was the last battle of the Revolutionary War. The French Navy accommodated with the Colonists and controlled the Chesapeake Bay. Blocking the ships of the British, General Cornwallis could not get ammo or food. Cornwallis relinquished to the Colonists. The Treaty of Paris was signed by the British, the newly formed United States, Spain and the Dutch.

Most people buy a book of some kind, usually the one that goes with the deck they have bought and learn each card as they go along. Remember that reversed cards have an altered or weakened meaning. Most books will also detail what this is. That is just the beginning. Although you can read the cards literally this will cut down on the amount of information you can give to a client. Intuition is a vital ingredient in Tarot reading. Very often a client will sit there trying to give nothing away which is up to them. Naturally, it is easier with a client who has something to ask so that you can approach the reading from that angle. However, you can still read a person from the vibes they give off and body language; a natural reader will do this without thinking about it. Now, when it comes to the cards themselves I would say that when you know the meanings you have to see which comes foremost into your mind. The books often give a string of almost unrelated words; this is to encourage you to see what fits in each circumstance. One of the words or phrases will stand out in your mind – this is the place to start. As you go along a narrative will come together and the reading will make sense. Also look for connections. Does any suit occur often within the spread (are there a lot of cups around)? What might this mean as part of the full picture? I often look at this once I have initially read each of the cards for the client, I try to give them an atmosphere of what is most significant in their lives at this time. Are there any shapes or forms within the cards themselves that re-occur? Does this strike you as significant? Of course, you learn as you go along and the more readings you do, the better you get at making the connections. If you’re new or fairly inexperienced at readings then have a go at doing a spread with no-one there just to practise making these connections and seeing what pops into your head. It might help to picture an imaginary person you might be doing the reading for. Look at it as coursework. It does no harm and helps you to become more fluent. === How Sensitive Do You Need To Be? === This is a question which raises itself from time to time when doing a Tarot reading. Often you do not need to censor what you are saying, but there are times when you have to judge just how wise it is not to say too much. Some people would say that you must always tell exactly what you see no matter what the consequences. I would argue that this is not true. Sometimes it is wiser to temper a reading a little. Be true to what the cards are telling you, but circumnavigate a hurtful core if you feel the person you are reading for is not going to be able to deal with it well. The vocabulary you use may need to be modified; you may need to discuss the card meaning in a more circumspect manner in order for the client to comprehend what it may contain before tackling the subject directly; you may need to use warning and possibility. Being a “sensitive” has two interpretations: being sensitive to the cards, what they are telling you and what is emanating from your client. On a more mundane level you have to be sensitive to peoples’ feelings. If someone comes to you for a reading, or advice, they are often vulnerable. They may be waiting to hear what they want to hear and this will make itself clear through conversation or a direct question that they ask. It is the tarot reader’s responsibility to act according to what they feel about the person before them. No one wants bad news, but sometimes it has to be told. If, like myself, you get images and feelings entering your mind as a consequence of the reading, but not directly part of it, this is often a sign that warning needs to be given and acted upon. For example, during a reading I once had a very strong impression of discomfort in the stomach area and said as much to the client who responded that she was having medical exploration to determine what was causing stomach problems which she had not previously mentioned. I had identified something that was on her mind but only tangentially on the cards. As a result we were able to discuss it and I was able to give her assurance that tackling the issue now was going to have a beneficial outcome and it was no real problem. Sometimes it is just a card that is giving a message and has no strongly associated psychic response. The Tower reversed: this cropped up recently and while I knew what it signified, the person I was reading for was in no state to take the news well. Instead I issued a warning in guarded terms and talked around the issue giving care advice in general which also related to the specific subject. It is a mistake which new and inexperienced readers make that they will go hell for leather into interpretation and give out dire warnings and forecasts for the pleasure of being right, rather than taking time to consider how to couch bad news. The element of drama is rarely necessary and taking the time to think and consider in a reading how you are going to put things across will pay greater dividends. === Exercise – Getting to Know the Cards === It is important that you let the cards become part of your consciousness. Some people recommend sleeping with them under your pillow to allow them to tune into your subconscious. Do so, if you wish, but it is not essential. The following exercise will help you to absorb information and foster familiarity: • Select a pack that appeals to you and keep it by you as much as possible. • Look through the cards on a regular basis, taking in the pictures on them. You do not need to learn the meanings at this stage. Simply let the images take root in your mind and imagination. • Pick a card and look at it for a minute or so. Close your eyes and see how accurately you can picture the card in your head. • Do this regularly until you feel you are familiar with the pictures. • You may get certain feelings from seeing the images in your mind; note them, but do not write them down at this stage. • Sometimes your imagination will make the characters move or you might imagine them speaking; again, note this, but do not write it down. The point is to get used to the tools before you begin working with them. It frees up your own mind and imagination in readiness for the work you will need to do to learn the meanings of the cards. The images need time to settle into your subconscious. It is a relaxing thing to do and informative. The images will work in their own way just as your mind will. NB DO NOT let others handle your cards. They are your tools and, just as in any other trade, you need them to work for you. Only hand cards to other people when you are going to do a reading for them and then only to shuffle. There is no need to keep a sense of mystery, just explain why you do not want people to play with them. Keep another set by, if you like, for people to look at – a curiosity pack. === INTERPRETATIONS - The Rider/Waite pack === I worked on these interpretations over about a year, picking cards at random after shuffling and writing down what they made me think on that day. I have a thirty-year acquaintance with the pack and so the meanings spring from the original stated meanings in the literature that accompanies the pack, from the illustrations, and from my own psyche in response to them. They are meant as a guide and are not definitive. === The Major Arcana === ==== 0 The Fool ==== Hang onto your hat and once more unto the breach! Time to take a risk and step into the unknown. You’ve been itching to do it for a while, but have lacked the courage. Now is the time. Get onto that top diving board and jump. Your life is in need of a radical shake up and what can you lose? Everything, or nothing. ==== 0 The Fool (reversed) ==== You seem to have some kind of death-wish as far as your personal development and career go. You take unreasonable risks and expect others to deal with the consequences. Some friends like to come along for the ride, but only because they are as reckless as you are. Others avoid you like the plague and would never employ you. Risk can be good, constant heedless risk is asking for trouble. ==== I The Magician ==== You have achieved a level of knowledge and control in a skill which is to be admired. Sometimes you may feel the need to show off about this – it is not there so you can lord it over people, but you must make the choice how to use what you have learnt. If you admire a person of similar skill watch them and learn. You are in a good place. ==== I The Magician (reversed) ==== Things are not what they seem. You are in contact with a trickster. Be careful of the influence this person will try to have; they have their own interests at heart. They love to blind you with science. Listen carefully and think about what might be true and what not. ==== II The High Priestess ==== Still waters run deep; you've been hiding something of yourself and now you know it is time to share it with everyone. They think you are so easy to understand, but this new revelation will make them respect you more. Share. ==== II The High Priestess (reversed) ==== You’ve been keeping a few things hidden and feeling superior about it. You indulge in your knowledge. People feel you look down on them – and you do! They find you intimidating and will tend to keep their distance. What is hidden can come to the surface when you least expect it and then you’re in for trouble. ==== III The Empress ==== Fertility is the name of the game here in all aspects. This card brings the blessings of abundance to those that surround it. Of course, this may be the sign that a new child is on its way. Alternatively, as a creative you will begin to produce what your public will appreciate; in business you may be about to make a breakthrough; in your personal life it is the sign of a time when you can achieve a happiness you have dreamed of. ==== III The Empress (reversed) ==== You have reached a position of stagnation. Your creative flow has ceased because you have become stuck in a repetitive cycle of behaviour. You must find a way to break out and take a new direction. Start to consider the alternatives in life: what can you do differently? Look around you for inspiration, talk to others, research – and then DO! ==== IV The Emperor ==== You respect this man in both opinions and actions. He is fair and just, but can be inflexible. Take advantage of his strengths while remembering he is no sensitive flower. ==== IV The Emperor (reversed) ==== This man has authority over you and he is a bigot. He looks down on you. No matter how hard you try, you cannot change his opinions. Do not be influenced by him. Move away before he erodes your self-worth. ==== V The Hierophant ==== Things are starting to get a bit spiritual, but make sure you are approaching with an open mind. Don't get blinded by dogma; your way forward requires discussion, but beware of a person who dominates. Pros and cons are important. ==== V The Hierophant (reversed) ==== This person is ruled by dogma. They know only the rule of what they believe, and they believe they are right. If you are on the wrong side of them, take care. Or it may be you who are too hidebound; make an effort to widen your horizons or you will suffer for it. ==== VI The Lovers ==== Life presents you with two choices now: you can remain as you are or move forward into a new relationship. The signs are positive in either direction. If you decide to move on with a relationship you should ensure that everything is secure. If you remain where you are, personal growth lies ahead of you. ==== VI The Lovers (reversed) ==== You are tied into a relationship that isn’t working any more. You see all the negatives, but daren’t move out of it. Pluck up your courage and move on. Conversely, you may be too attached to your way of life to get into a relationship. Grow up, leave your parents or your routine behind and move towards the maturity of bonding with someone you like. It may be scary, but it is what you need. ==== VII The Chariot ==== You have gained control over various parts of your life that have been pulling you in different directions. All this has taken its toll on your psychological health, but that is now also becoming less of a problem as you gain confidence. People respect you for the sense of direction you have found. They will follow your lead if you need them to. ==== VII The Chariot (reversed) ==== You’ve spread yourself so thin that you’re practically being pulled in half! You have been trying to control too many situations. Either your ego needs to always to take control, or you are too timid to say no. This must stop because you are heading for a meltdown. Prioritize and pull out before it is too late. ==== VIII Strength ==== People are wondering how you can be so serene and yet manage the things you do. You can’t see what’s so special about it. You are more about getting on with things than “coping”. You don’t see most things as a challenge, but when you do want a challenge you will attempt the impossible and probably achieve it. Remember to recharge your batteries from time to time. ==== VIII Strength (reversed) ==== Well, aren’t you the passive-aggressive one? It is no good putting your opinions out there and not backing them up with action. A little sniding behind peoples’ backs is not the way to go. You need to get some backbone and fight for what you believe in. Go take some assertiveness classes and then stand by what you say. Earn some respect. ==== IX The Hermit ==== Proceed with caution and look at every step ahead. A new situation requires careful planning. You have the experience, but are not confident in yourself. Don’t be afraid to ask advice, then act on your own reaction to it. ==== IX The Hermit (reversed) ==== Do you really want to keep yourself so much to yourself? You are becoming too isolated from friends. You are becoming too timid to get on with life and this is not good for you. Make the decision to go out one day this week and do something you used to do, but have given up on. You need to see that the world is not as frightening as you think. ==== X Wheel of Fortune ==== Aren’t you the lucky one? Luck is right on your side at the moment, but make the most of it because it will turn. Be prepared for things to get a little harder now in whatever direction you turn. If you don’t you will be in for a big shock. It is too easy to be complacent; plan for the harder times and it won’t be so bad. You can still be successful, you will just have to think more creatively about how you approach life. ==== X Wheel of Fortune (reversed) ==== You have reached a nadir; luck has not been on your side. You may have been trying to fight it and this just wasn’t the time. From now things should start to improve. Don’t expect a massive lottery win, just an easing of the situation. Now you should put effort into what you want to achieve. ==== XI Justice ==== Remember to keep perspective. You have to sort out this situation and mustn’t be blinded by prejudice. If friends are asking you to help arbitrate then you need to look at both sides and make a rational decision. The result may be crucial for your life or someone else’s. ==== XI Justice (reversed) ==== You are looking in the wrong place for a fair hearing. You keep asking people to back you who only have their own ends in view. You will suffer more if you carry on. It is time to look elsewhere, to those who believe in you. Change your situation, you can’t win. ==== XII The Hanged Man ==== Some things have to be got through and that’s the point you’re at. You will see the situation clearer afterwards, but for now you have to bear with whatever you are feeling. Know that your present situation will end and mend; it is a positive experience even if it doesn’t yet feel that way. ==== XII The Hanged Man (reversed) ==== Is it really worth all the suffering? You are going through a bad situation, but you have sought it yourself to some extent. Now you will have to put up with the experience and it won’t be a pleasant one. Once it is over at least you will have learnt a lesson. Ensure that you know what the end is going to be before you subject yourself to the means! ==== XIII Death ==== There is an inevitability about what is going to happen to you. Your life will be completely transformed and you are about to make a completely fresh start. You were not expecting this and it is all the more powerful because of that. Remember this is a positive time even though you are leaving behind all that has gone before. You will be so much better for the change. ==== XIII Death (reversed) ==== Far more positive than it looks, but the same is true as when the card is upright: a complete change of your life is about to occur. You will not welcome it, but you have to come to terms with it. It is what you need, not what you want. The universe has decided to alter your direction. Go with the flow and embrace the change, if you don’t then much heartache will follow. Allow yourself to adapt, it will be better. ==== XIV Temperance ==== It’s time to concentrate on making a situation appropriately fit for development. You are working towards an important goal and you know the circumstances need to be just right, but you’re a little unconfident. Don’t worry, you have the intuition to work out what needs to be done. You can combine the circumstances and people to get where you want to. ==== XIV Temperance (reversed) ==== You cannot do one thing instead of another, there has to be a balance. You are trying to force your life into a certain path even though you really know that you should be following a middle way. Temper what you don’t want to do with what you do. If you keep forcing the issue you will become stressed. Sit back and think, make notes, work it out or you will pay the price. ==== XV The Devil ==== You are attached to a particular way of living and thinking. You remain blinkered to any life choice other than the one you have made. Those around you support you in this attitude. You wonder why you feel frustrated. It is time you asked yourself a few pertinent questions about where you are heading and did something about your stagnation. Your views on others need updating, too. ==== XV The Devil (reversed) ==== If you sup with the Devil you will need a long spoon; you’ve made your bed and now you must lie in it. You have wilfully been making choices which you knew weren’t for the best, but have done it to spite others. You’ve had your enjoyment, but now you will have to pay for it. Maybe financially, emotionally or professionally, but you have only yourself to blame. ==== XVI The Tower ==== A sudden and dramatic event that shatters your world. It is a clearing out of the old ready for the foundations of the new. You will have a period of shock, then readjustment, but it is all for the good. If you have an injury, it will make you reassess your life; be assured it will pass and you will be renewed, but with a different perspective on things. ==== XVI The Tower (reversed) ==== Unexpectedly catastrophic. An event you weren’t expecting changes your life. You have believed in something with foundations of sand which you couldn’t see. Maybe the end of a business or it could be a personal injury. It is time to start building again when you regain your strength. ==== XVII The Star ==== Ever the optimist, you are hoping that things will turn out right. You have the ability to create the proper circumstances. Take a measured view of what you are beginning and look to blend the elements you need to make it work. You are a great support to so many people because you always have faith. ==== XVII The Star (reversed) ==== You spend too much time hoping that things will turn out for the best. You need to put some effort into shaping your destiny. You can’t keep blaming other people and fate for what is not right in your life. Find a way to become more active – exercise, set goals and do what you need to achieve them. Stay as you are and depression is your only friend. ==== XVIII The Moon ==== Start relying on your intuition; it's working well at the moment. Add to it a bit of common sense and you'll be a force to be reckoned with. Ward off any tendency to melancholy with a shot of what makes you feel good. ==== XVIII The Moon (reversed) ==== You're out of balance just now and your head doesn't feel like it belongs to you. Worry is your constant companion. Try meditation or just relaxation techniques, but don't focus on what's bothering you. Wait for this time to pass - it will. ==== XIX The Sun ==== And it all comes together. You’ve been striving for a while and all that work finally pays off. Remember, this isn’t the end; it is just the beginning of something new and better. You can bask for a little while though. ==== XIX The Sun (reversed) ==== Try as you might you can’t get to the level of expertise you need. You’ve been trying hard for a long time, but it isn’t working. Time to change tack. You have other skills and your brain is ready for new challenges. Carry on as you are and you will fail again. ==== XX Judgement ==== Wake up and smell the coffee! It's time to get out and do something; you've been lazy for too long. Somehow you've got into a rut and you know you need to do something about it. You've got the energy and the ability and now is the time to use it! ==== XX Judgement (reversed) ==== Don’t just sit around giving your opinion, get out and do something about it. You pontificate and bluster, telling people how to live their lives while yours is slowly stagnating. You need to give yourself a good kick and move onto a more positive outlook and get active. You have a lot to offer, if you can offer it in a more motivating way. ==== XXI The World ==== Now is the time when everything comes together; you can meld your achievements. Take stock of what you have in your store. Soon it will be time to move into a new cycle of life and you must take what you have learnt and challenge yourself once again. ==== XXI The World (reversed) ==== Sealing yourself away and feeling you know it all is not the way forward. Do you really think you have reached your full potential? Get real and get out there. You may have reached a point of conclusion, but this is also a point of departure in another direction. Get over yourself! === The Minor Arcana === ==== Ace of Wands ==== Get ready for the start of a new enterprise. You’ve got the push to do it, you’ve got the ideas. Now is the time. Don’t lose confidence. Bring in positive people that you know can help you; they will respond to firm leadership. Go for it. ==== Ace of Wands (reversed) ==== Now is not the time to be starting a new venture. You’ve got all the ideas, but are not quite prepared. Someone who is offering to help out is not reliable; they mean well yet are not committed. Make sure you do more groundwork and then start when you are sure you are ready. ==== Two of Wands ==== You’ve worked hard to get to where you are and now you are faced with the choice of moving to another place. There is a promotion for you, but you will have to make a change. Are you prepared to leave your present life and move a fair distance? Weigh up the pros and cons. This is what you have been working for, be brave and make that step. ==== Two of Wands (reversed) ==== You spend too much time thinking about travelling the world, but never do it. You keep waiting for work to lessen and say "one day" will be right to do it. Get on with it, or that "one day" will never come. ==== Three of Wands ==== You’ve got a longing to move further afield, but are wary about what that may mean. You are secure enough to be able to move on. Don’t be afraid to leave your work behind: a new job in a new place is what you need. It is time. ==== Three of Wands (reversed) ==== It’s no good thinking what would have happened if you lived further afield. You get lost in wondering about wandering, but let work keep you fixed to the spot. Now is the time when you need to break loose. Only your mind ties you to this place. ==== Four of Wands ==== You feel a celebration approaching: it’s time to take some reward for all your work. This may be in your career, study, or an achievement you’ve been working towards. You deserve to be praised for what you have done. Others will be happy to join in, even if you don’t realise how much they appreciate you. Party! ==== Four of Wands (reversed) ==== The harvest is over and it is time to start preparing for the next one. You have a few foundations to lay for the next part of your career, but you seem to be hesitating. Take some time to think, or make a list of what appeals, then pick one and get on with it. ==== Five of Wands ==== Fight the good fight – that’s the way to do it! You know when something is fundamentally wrong and you are prepared to put yourself on the line to say so. Other people appreciate this in you. You state your case well and don’t go shouting the odds. You know how to succeed, but also when to back down. Just make sure you keep the others backing you when you need them, don’t let them shirk it. ==== Five of Wands (reversed) ==== Things are getting nasty at work: too many people are struggling to dominate a situation. You need to take a step back and honestly assess what is going on. Stress will be the result otherwise. Is it time for a change? ==== Six of Wands ==== What you have achieved is by your own hard work. Enjoy the position you’ve reached, but don’t let it go to your head. You have a responsibility to others. Ensure they are working with you as well as, possibly, for you. Help them do their best. ==== Six of Wands (reversed) ==== You have reached a certain position at work and now you think you are so far above everyone else. Remember you are part of a team; you may lead or manage them, but you would have no work without them. You are not popular with your colleagues just now. Think about what you can do to change that. ==== Seven of Wands ==== You have to defend your position, make sure it is the right one. You feel as if you’ve been backed into a corner and you have to fight for the weakest. Make sure the fight is worth it and that you get recognition. Try to ensure you keep things calm. Seven of Wands (reversed) Why battle with your workmates? There's no point as it only drains your energy more. People make so many demands on you - are you a soft touch? Take stock and do something about it. ==== Eight of Wands ==== You’ve been so efficient lately that everyone wants you to do some work for them. You are full of confidence and your prioritising skills are working well. Don’t take on more than you can handle, though; you want your reputation for efficiency to stay intact. ==== Eight of Wands (reversed) ==== It never rains but it pours. Everyone wants your attention and your help and you just don't have the physical resources at the moment. Take care of yourself; they can help themselves if you leave them to it. Don't take phone calls from work. ==== Nine of Wands ==== You are feeling totally isolated and overwhelmed by your work. How did you get into this position? You kept accepting a bigger workload. Learn how to say no. It is making you aggressive and unpleasant to be around at work and at home. Find a better work-life balance. ==== Nine of Wands (reversed) ==== You are feeling intimidated by circumstances at work. It feels as if everyone is against you. Work to find out who your allies are, you are not alone, but don’t realise it. Maybe it is time to change your job, or to alter the conditions. Speak out about it. ==== Ten of Wands ==== You are at the point where you have the strength to take on more tasks at work. Could be that a promotion is being offered. You have the experience and the stamina, so take it. If working for yourself; now is the time to stretch yourself. There are new challenges to be faced. Just make sure you know when to cut back and always include plans for breaks and holidays for your well-being. ==== Ten of Wands (reversed) ==== You will keep taking things on. Remember you work to live not live to work. Hand over some of those jobs you don't have to do. Delegate is the word of the moment. ==== Page of Wands ==== If you can get past this person’s “know-it-all” persona about work they are quite nice to know. They can’t help how they are and maybe need more social contact. You might be the one to make a difference. This person can be single-minded, but they also have potential to be fascinated by the world outside of work, they just don’t realise that – yet. ==== Page of Wands (reversed) ==== Beware, there’s an office sneak around. This person seems to be nice and friendly, but they’ve got ambition and they will do anything to get ahead. They watch and they tell tales to make themselves look better. Not a liar, but someone not to be trusted. If you’re in a relationship with this person remember they will keep nothing to themselves. ==== Knight of Wands ==== He’s a big, solid hero. So what if he isn’t that bright? He’ll be as faithful as a hound with eyes to match, especially if you hurt him. He is sincere and honourable. He’ll do most things to make you happy, and if you are happy, he is happy. He won’t go down the line of intellectual conversation and games of chess, but if you’re happy with that, go for it! ==== Knight of Wands (reversed) ==== He’s not the sharpest knife in the drawer; bigger on brawn than brains and that is going to be a drawback. He does not do sympathy or empathy. “Charging in like a bull at a gate” is the phrase made for him. Quick physical relationship – yes, long-term partner – no. ==== Queen of Wands ==== It’s true she can be a little aloof, but she’s nice really. If she is your boss, you are a lucky person. She understands business and how to motivate staff, and she is always open to ideas and discussion. She is no pushover, though. If you are in a relationship with her then you might find her more driven by her career than passion. ==== Queen of Wands (reversed) ==== A harsh disciplinarian, she rules with a rod of iron. Do not expect this woman to take excuses. She expects you to do your job to the best of your ability. She is never off sick and expects her co-workers to be the same. At times she will demand too much. Be firm with her and don’t let her exploit you. If she sees you are weak she will take advantage. You must be prepared to deal with her or get yourself another job for your own sake. ==== King of Wands ==== A boss-type who can be relied on. If he’s your boss you need never fear asking his advice, it will please him, but don’t let him down by inefficiency. If you are in a relationship with him you may find that he sometimes has more mind on his work than on you. He’s basically decent, so this might be worth putting up with. ==== King of Wands (reversed) ==== Your boss is really putting the pressure on you just now, but you don't have to take it. Put your foot down no matter how hard it may be. Let them know you're not a wage slave. Learn to work hard, but don't overdo it. ==== Ace of Cups ==== At last a relationship that’s going somewhere. It’s just the start of a good match and everything is blissful. Don’t get completely lost in the relationship; it is part of a wider life. Make the most of where you match and learn to respect your differences. ==== Ace of Cups (reversed) ==== You’re wasting so much emotional energy, take some time out. You need to be alone to reconsider and recover. You have so much to give yet you don’t give to the right people. Shed the ones who drain you and give nothing back. ==== Two of Cups ==== Sharing is a good thing, mutual sharing is even better. Now is the time to examine a potential partnership and ask if you understand each other. It’s time to talk, find common ground, where you differ and discover how to make it work. ==== Two of Cups (reversed) ==== Remember that bargaining in relationships is a two-way thing, be sure the other person understands what you want and don't just take it for granted. Listen to what they want. You are in danger of not putting enough effort into your current partnership. ==== Three of Cups ==== Raise a glass to the party season. It’s time to enjoy yourself because you’ve earnt it. You’ve been supportive to your friends and they have decided to reward you. No false modesty – you should make the most of the opportunity. There will be time to come back to earth afterwards. You are a good and loyal friend and that isn’t going to change. Be thankful that you are appreciated. ==== Three of Cups (reversed) ==== You're feeling closed out of the love at the moment. You've been trying to get into that crowd and, while they accept you, they don't really think of you as one of them. Maybe it is time to move on, find others who are more likeminded, and leave those "good timers" to themselves. ==== Four of Cups ==== The good things keep coming at the moment and you do right to enjoy them; you have done your best to achieve. Good things come to those who wait. This may be a time when you get to choose a relationship from a few who are looking at you. Or it could be that the good feeling and support you have given to others is returning home three-fold. ==== Four of Cups (reversed) ==== You cannot be an emotional sponge and expect people to worship at your feet, or satisfy your whims. You need to give out more. Have a good look at yourself and ask what you can do to empathise with others. Work on giving more emotional support. ==== Five of Cups ==== You are upset because you seem to have wasted your time, but it’s not true. You’ve lost some of what you achieved yet there is some good feeling stored for you. Look to progress in a different direction. What you have done will be useful. There is a way forward. ==== Five of Cups (reversed) ==== You have withdrawn so far into yourself considering your "wrongs"; you really think other people have done badly to you. Pay more attention! You have unfulfilled potential and you're just not looking in the right direction to see it! ==== Six of Cups ==== A little bit of specialness is coming your way. People are going to show their appreciation for your care and concern. It is time to enjoy things coming your way which you didn’t expect or ask for. Take a bit of time to be happy, relax in the respect and love of your friends and family; you can get back to looking after them later. ==== Six of Cups (reversed) ==== You feel unappreciated and maybe people are not taking enough notice of the things you do for them. Don’t be afraid to drop some hints, they are maybe just being a bit thoughtless. You do tend to brood about these things and makes you a less generous person. Don’t let this affect who you are. After all, you know you are a considerate and helpful person and, sometimes, that should be its own reward. ==== Seven of Cups ==== It's party time! But don't just go for the sake of it, decide why you need this. You spend too much time dreaming. Make things happen. ==== Seven of Cups (reversed) ==== You spend too much time thinking about what you deserve and not enough going out to get it. If you want something you've got to work for it. Get your head out, and your hands working - you can do it! ==== Eight of Cups ==== Now is the time to start exploring the unknown. You've enough resources to do it, and if it doesn't work out there are no worries for when you get back. It may be time for that venture you never dared. Remember those close to you care. ==== Eight of Cups (reversed) ==== Oh, you just love walking away, don’t you? This tendency to turn your back on the good things and go searching for another goal is damaging your life. You must make yourself turn round now and again, take stock and see the good things for what they are. People don’t trust you enough to involve you because they are afraid you will leave them at a crucial time. ==== Nine of Cups ==== You are not the guardian of emotions, you are merely an advisor. Share what you have learnt and help others to learn from what you know. You would make a good agony aunt, but don’t be tempted to take the high moral ground. People like you and trust you and this will pay back dividends of love and devotion. ==== Nine of Cups (reversed) ==== A bit too self-satisfied at the moment. You sit there giving your opinion and advising others on their love lives without much justification. You must stop bullying people into taking your advice. Spend some time observing people and learning. You do have an intuitive understanding of emotion, but must learn to develop it more deeply and use it in a much more positive way. ==== Ten of Cups ==== Talk about “everything’s coming up roses” – and it is! A time to be thankful for the good things in your life. Make sure you share them with others. In fact, it’s not a bad time to have a party. Throw one just for the sake of it and get all your friends together, it will be one of the best you’ve ever had. ==== Ten of Cups (reversed) ==== You still have a way to go before you can celebrate. Your family may be pressuring you to hold a great party; if they want one, let them throw one. You have business to sort out, either work or some matter relating to those closest to you. Once you have settled that you will be able to do your own celebrating in your own time. ==== Page of Cups ==== What a cute little love-bundle! Fallen on your feet here with someone who is so affectionate. Beware, though, they’re easily hurt. This person likes to have fun and do quirky things on days off. Interesting in conversation and very outgoing. They are loyal and just a little bit clingy. Check the cards around this one to gauge more about personality. ==== Page of Cups (reversed) ==== This one’s a sneaky one. Will definitely lead you on because they thrive on people who fall for them. A kind of emotional sponge. Male or female, they like to whip up a sense that a relationship with them is about to happen, then they disappear without committing at a crucial moment. ==== Knight of Cups ==== He’s cool, calm and collected; he has a practical and caring approach to life; he is honest about what he has to offer. This might be just what you need. However, if you’re looking for passion and excitement, you’ll have to discuss it with him first. As a friend, this is someone who you can talk to at length and who will always give good advice about relationships of all kinds. ==== Knight of Cups (reversed) ==== This one can be the classic love rat. He is so confident and makes you believe that you are the one, but that’s what he does to them all. He can hold conversation, he can be attentive, but once he is bored there will be someone else on the horizon. You are probably too sensitive to take him for what he is. It may be difficult, but tear yourself away and wait for someone who responds to you. ==== Queen of Cups ==== Cool, calm and collected, she carries a soothing atmosphere about with her. You go to her for quiet chats over tea. It is not so much that she shares wisdom than that she encourages wisdom to emerge from those around her. You respond to the flow of spirituality from her that helps you see other perspectives. ==== Queen of Cups (reversed) ==== Oh, she loves to give advice about love and relationships, but she is clueless! She just wants to be involved. Don’t take advice or trust her with your innermost emotional secrets. She is probably a fan of online dating and runs an advice column in her parish magazine. Amusing enough in her own way as long as you don’t take her seriously. Couldn’t keep a relationship of her own going to save her life! ==== King of Cups ==== Firm, but fair – that’s how to describe him. He has a clear mind when it comes to affairs of the heart and is someone to go to for advice. To some he can seem a bit stern, but he’s a softie, really. He has a sense of fairness when dealing with people. A bit of a stay-at-home, though. He probably makes a good cup of tea. ==== King of Cups (reversed) ==== He's very generous of heart, but not what you need right now. His advice is too sentimental and while you may admire his qualities, he is not the person to look up to. You ought to be giving him advice rather than vice versa. ==== Ace of Pentacles ==== Success beckons and you have the know-how to achieve it. Do not be over-confident because there is still work to do. You know you will help others when you get where you want to be, but don’t tell them yet. A little more effort is required and the rewards will be yours to do with as you please. Of course, you have to work out how to remain successful once you get there, and yes there is some wealth here. ==== Ace of Pentacles (reversed) ==== You’ve been too preoccupied with money and now you’re paying the price. People think you are money-orientated and selfish. You are hoping to set yourself up for the future, but you have been using some pretty dubious methods. Re-think your strategy; there are more straightforward ways to make money. There is also more to life. ==== Two of Pentacles ==== Yes, you are very good at balancing, but at the moment you need to put away something for the future because there's a big travel opportunity coming and you've been too busy spending on other things. You can do it; set your mind to it. ==== Two of Pentacles (reversed) ==== You have spent so much time weighing up your options that it has become a hobby! You cannot procrastinate forever; you need to make a decision. It is probably time to move on, but you lack the courage to do so. The world would be your oyster if you dared to open it. Also, people are getting fed up of hearing you discuss whether to move on or not. ==== Three of Pentacles ==== It is time to consider charitable giving. Choose your cause well, after all it is your hard-earned cash you’ll be donating. Perhaps there is a skill you can use to help a charity or good cause – this can be worth more than money. Follow your instincts and you will feel the glow of generosity that does not draw attention to itself. ==== Three of Pentacles (reversed) ==== Don’t get too involved in a project you are currently working on. You need to keep an eye on the finances. Someone is making money out of it in a way you haven’t seen. You have been too generous with your skills. Pay attention to those who got you involved, ask a few questions and make sure they are paying you what you are worth. ==== Four of Pentacles ==== You are very sensibly keeping your money by you or investing it wisely. You have some ideas about how to attract more. Be warned, though, you could do to spend some of it just to spread the love a little. Could you endow a charity? Don’t be mean to yourself, and don’t be seen as a miser. You could give a little help here and there. ==== Four of Pentacles (reversed) ==== What good is just sitting on your cash and being scared to spend anything? You are giving yourself a really hard time and people are calling you a skinflint. Even spending on basics is becoming a problem. You must get a grip on this situation. Look at it rationally: money has to be spent to live and you are not poor just now. Budget, by all means, but get over the problem you have with spending! ==== Five of Pentacles ==== Your endeavours are a beacon of hope to some people. You have been involved in fundraising or charitable work and are beginning to see the fruits of your labour. You still feel there is lots to be done and have the knowledge and strength to do it. You can persuade others to join you and they will, willingly. Keep it going while you have the drive, and prepare a network to help you. ==== Five of Pentacles (reversed) ==== You seem to be feeling left out, marginalised. You must ask yourself what makes you feel like this. Is it true and what is your way forward? You have been injured by circumstances, but there is hope. Your forward path will be hard and ultimately rewarding if you take it. Now is not the time to stay as your are or wallow in self-pity. Take small steps, but take them. ==== Six of Pentacles ==== Not only are you being generous with money at the moment, you are also helping others to sort out their finances. Plenty will come to you for advice – don’t let this go too far. Keep a perspective and help those who you feel really need it. It could be time to work with one charity or good cause that you really empathize with. You have a wonderful talent for helping others; make the most of it, but don’t squander it. Enjoy what you’re doing just now. ==== Six of Pentacles (reversed) ==== It is no good giving away money you have not got. You like to be seen as a charitable person, there is your fault. Charity should be done out of sight if it is personal; don’t look for praise from others for doing it. You can turn this around, organise a fundraiser and get others to enjoy themselves while donating their money, then everyone will be happy. ==== Seven of Pentacles ==== Take satisfaction in what you have achieved; it has been through your own hard work. Remember it is a sign of what is possible. Continue the hard work and don’t rest on your laurels. Encourage others to take inspiration from your actions. ==== Seven of Pentacles (reversed) ==== You feel that you aren’t getting rewarded enough for all your hard work. You seem to have been toiling for ages and yet the returns are pretty poor. Try not to dwell on it and maybe look for another way to earn what you need. If people don’t value you, then perhaps you need to change the people you work for, or the way you work. Conversely, are you, perhaps, overestimating your worth? ==== Eight of Pentacles ==== Now is the time to put your back into things. You have the skills to make some money out of your craft, but you can’t just sit back and expect it to happen. You have to market yourself and make sure you can deliver the goods. Keep those skills up to speed. ==== Eight of Pentacles (reversed) ==== You’ve been working hard and not getting your just rewards. Maybe you feel too obliged to work above and beyond the call of duty. If you don’t feel confident enough to stand up for the proper reward then look for someone to help you. Carry on as you are and you will be worn out and poorer, financially and spiritually. ==== Nine of Pentacles ==== You can take it easy for a while; investments you've been making in time or money are paying off and allow you some relaxation. It won't last forever, but make the most of it and use some of the time to plan ahead once more. ==== Nine of Pentacles (reversed) ==== You have been drifting along in a world of your own thinking spending doesn’t matter and now you’ve found out it does. Re-organise your finances and start making savings. You need your money to work for you if you want security in the future. A useful lesson to be learnt here. ==== Ten of Pentacles ==== You are in a place where money is all around you. Think carefully about what you do with yours. You may be tempted to spend what you do not have. Watch, listen and learn: you will know where to spend sensibly. Is this a time to give charity? ==== Ten of Pentacles (reversed) ==== You keep thinking that your life should be all easy living and plenty of money; this is going to get you into financial trouble because you aren’t earning enough to keep you. You need to start working a lot harder and playing a lot less. You might be able to fool those who want to live off you in the good times, but those closest can see what is happening. You might be needing them shortly. ==== Page of Pentacles ==== Someone you can trust with financial control on a business level, or as a salesperson because they know how to get people to spend. Probably not very good on a social level, but likeable enough. You’re more likely to have a coffee and a chat with them than a relationship. ==== Page of Pentacles (reversed) ==== This person does go on and on about money. They may be good at investments, but are pretty poor at conversation. You need to take them aside and have a word about socialising. They mean well and are quite pleasant. You seem to have taken them under your wing; be sure you know what you’ve taken on because your other friends aren’t likely to want him or her around much. ==== Knight of Pentacles ==== It’s true he’s not the most interesting man in the world, but he’s nice and he’s good with money. He is the sort to spoil you from time to time. He is also the sort to help you sort out your investments. Practical, reliable, and probably quite good fun at the seaside. ==== Knight of Pentacles (reversed) ==== You know how to pick them, don’t you? Money obsessed, this one, won’t spend a pound if he can get it for a penny. You’re in for some “interesting” nights out – fixed menu rather than à la carte and youth hostels rather than country house hotels. He tends to attract friends like himself so make sure you have your own social circle to fall back on. He means well and probably has those “city man” looks. You could do worse. ==== Queen of Pentacles ==== It's time to consult this woman about the way you manage your financial life. She's an expert without being a professional. Your earning potential is good now, so make sure you don't squander. Whatever, she's a warm, sociable person you should spend a little time talking to now. ==== Queen of Pentacles (reversed) ==== She isn’t one to take shopping unless you want your card maxed out. If she’s a friend then she will constantly be encouraging you to spend on things you don’t need or can’t afford – and you let her! Get a grip. She’s a nice person, but keep her in the “just meet for coffee” bracket. Also, she knows nothing about finances yet will constantly give advice about managing money. Let her do it, you ignore her advice as you smile sweetly. ==== King of Pentacles ==== You might feel he’s looking down on you, but that is just his way. He is a pleasant person, a little slow in speaking. You could never describe him a dynamic. He is wealthy and a good person to pick the brains of about investment. If he is your boss, he will be just and fair though not one to share his money. He gives rewards where they are due. If he is your partner, remember he is not into buying presents and you will need to make a good case for new things about the house. ==== King of Pentacles (reversed) ==== He’s a slow and deliberate person who appears to be giving things a lot of thought. It is his way of covering his disinterest. You think he’s got depths of wisdom; he might have, but he’s not going to share them with you. He likes the idea of you following all he says, especially when it comes to financial matters, but he wouldn’t give a damn if you were suddenly penniless tomorrow. ==== Ace of Swords ==== Now is the time to show your strength of mind. You must apply your skills to whatever you want to press forward with. Maybe people will be asking for your views and help – they trust your vision and pragmatism. Don’t let your ego become too dominant, though; remain humble yet helpful and strong. Quietly enjoy the satisfaction all this brings. ==== Ace of Swords (reversed) ==== You are being to combative. You can’t beat people into submission with your wily ways just to get them to agree with you. Rethink your strategy because you will make more enemies than friends if you keep trying to browbeat them. You have something you want to achieve – fine, but get your friends onside. ==== Two of Swords ==== You have to make a decision and are trying to be impartial. You are right to use your common sense rather than be guided by your heart. Your friends value you for this ability. At present it is your strongest asset. ==== Two of Swords (reversed) ==== You have backed yourself into a corner and cannot see a way out. You need to cultivate an open mind and approach your problem anew. Speak to others; you have been silent and relying on your own resources for too long. ==== Three of Swords ==== You couldn’t be at a lower ebb emotionally than now. You’ve given a relationship all you’ve got and it hasn’t worked out, or you’ve been wasting your love on an unworthy object. Remember, this is something you have to go through to learn more about yourself. It will end and you will be more resilient. Don’t let this spoil the love you have to give. ==== Three of Swords (reversed) ==== It is no good moaning about your broken heart because you knew what you were getting into when you started. Friends warned you, so only the odd one will be sympathetic. You have got to get over the hurt and start again, but learn the lessons from last time. You need to go into an uncomplicated relationship; take your time, make sure it’s the right person! ==== Four of Swords ==== You have to work against a feeling of gloom. You fear responsibility and yet you are well able to handle it. Now is the time to work on your confidence. You have the inner strength to deal with what life throws at you just now. Four of Swords (reversed) You're losing too much sleep and the things you're worried about are better sorted out in the light of day. Set your mind to a plan of action; ask friends to help. You can't sort this out alone, but it is do-able. ==== Five of Swords ==== You have a gift for dealing with the messes other people make of their lives. You thrive on sorting it out, but preserve yourself by not getting personally involved. Your skills are needed now. Be careful not to alienate yourself though, you will need those friends one day. ==== Five of Swords (reversed) ==== You’re inviting bad karma because of your behind-the-back attitude to others. You cannot take other people’s achievements and use them for your own glory, you will get found out. Look at your own life; you are resourceful, but you must use that positively. Carry on as you are and you will lose friends and the trust of colleagues. ==== Six of Swords ==== There’s nothing wrong with voyaging into the unknown and you’ve picked the right time to do it. It was an impulse when you received the offer, but it is all to the good. You will have a few sleepless nights, but once you arrive it will be worth it. Take your courage in both hands, get packed, say your goodbyes and off you go! ==== Six of Swords (reversed) ==== You’re being intimidated or forced in a direction you don’t want to go, but you feel powerless. You must talk to friends and enlist their help. Now is not the time to go with the flow. Stop blaming yourself for this, though, it has come about because of others. You do have a choice. ==== Seven of Swords ==== Don’t think you’ve got away with it, you haven’t. Take what you need from your present situation and be honest about it. You might need to be skilful in how to put things; otherwise your conscience will get the better of you. ==== Seven of Swords (reversed) ==== Watch out to see who’s talking behind your back. Someone is being especially malicious and, if you’re not careful, you will keep hearing about it second hand. They are smearing your reputation. You are in for a difficult time psychologically; the worry will be as much about where the rumours are coming from and what they are. Remember to keep your integrity; it isn’t true and you know it isn’t. Keep your ear to the ground to help avoid this. ==== Eight of Swords ==== Keep calm and you can find your way out of this. You have to think laterally as the solution isn’t the obvious one. If you have a problem with other people then you have to work out their motivation. Tread carefully and think. If you panic matters will get worse, but with patience you will find the solution you are looking for, just not in the obvious place. ==== Eight of Swords (reversed) ==== You don’t know which way to turn and everything is confusing you. You are in need of a trustworthy friend who can advise you. No matter what you do, nothing you can think of will get you out of this situation. You are struggling hard, no one involved is making life any easier. There is a way out, you just need someone to show you it. ==== Nine of Swords ==== You keep being seized by dread; this is something working its way out of your system. It is a cleansing process, not pleasant, but something your mind needs. You’ve been through some bad stuff. It is over now although recovery takes time. Bear with it, your night’s will not always be filled with lack of sleep. Keep telling yourself there is light at the end of the tunnel. ==== Ten of Swords ==== Things are the worst they can be which means they can only get better. You are feeling lost and friendless. Look around, make the effort no matter how hard it is, and you will see that there is light at the end of the tunnel. All the clichés count now because you can move on to better things. ==== Ten of Swords (reversed) ==== Depression may hit you like a ton of bricks. For too long you have been struggling on your own to cope with a situation where you needed help and support. This means you have alienated some of the people around you who could help. Now is the time to seek them out. Be honest about how you’re feeling and what’s going on. ==== Page of Swords ==== This one’s a combative one. You’ll have plenty of healthy disagreements. Just because they’re strong-minded doesn’t mean you two aren’t a good mix. You should spark each other off and have a whale of a time. Others will enjoy being around you two. ==== Page of Swords (reversed) ==== Like a bull in a china shop, this one. Ham-fisted and clumsy, but never with malice, they make their way blithely through life with barely a care. They are good fun to be around, but can be an annoyance to your friends. They do get upset if they think they’ve upset someone and you will need to be supportive; they would be equally supportive of you. You might need a safety helmet when you go out with them; you’d have a good time anyway. ==== Knight of Swords ==== What a whirlwind! He’ll whisk you off your feet, and no mistake. This is a real man of action. Be careful, though, he does have a tendency to mess with your head. He is very proud of himself and anyone he partners with is supposed to feel lucky to get him. Work out how he ticks before you commit. It could be a very fire-y relationship. If he’s just a friend or colleague then keep an eye on his rash decisions, they might need reigning in. ==== Knight of Swords (reversed) ==== And he seemed such a dynamo at first! Watch out for this one, he seems as if he's going to sweep you off your feet, but all that energy is also masking someone who likes to be in control and doesn't want to discuss it! ==== Queen of Swords ==== Firm, but fair - you need this woman to advise you at the moment. She's older and wiser and she will give you her unbiased opinion. You could learn a few lessons from her as well because you can be the same if you try. ==== Queen of Swords (reversed) ==== Backbiting is this woman’s favourite passtime. She doesn’t miss a thing and she’s prepared to talk about it. She will try to make you do what she wants and will talk and talk to get her own way. She will want to come between any close relationship. ==== King of Swords ==== He’s there for a purpose, reliable and steely. Common sense and a sharp mind are what he brings to the table. Personally, you’ll need to be yielding, but not soft. Professionally, he’s a good ally and won’t play dirty. A very intellectual and precise man. ==== King of Swords (reversed) ==== You know he’s not going to be pleased; he is never pleased. This man likes to twist the psychological knife. When you can avoid him, do. There is only one way to live life as far as he is concerned. Be careful if he is on your side; if not – beware. http://www.amazon.co.uk/Original-Rider-Waite-Tarot-Deck/dp/0712670572/ref=sr_1_1?s=books&ie=UTF8&qid=1403701052&sr=1-1&keywords=rider+waite+tarot+cards 01sx5izbyqciaq97ig0jizvlj6ftu4n 0 171005 2816824 2816711 2026-06-25T14:24:36Z Young1lim 21186 /* Geometric Series Examples */ 2816824 wikitext text/x-wiki Many of the functions that arise naturally in mathematics and real world applications can be extended to and regarded as complex functions, meaning the input, as well as the output, can be complex numbers <math>x+iy</math>, where <math>i=\sqrt{-1}</math>, in such a way that it is a more natural object to study. '''Complex analysis''', which used to be known as '''function theory''' or '''theory of functions of a single complex variable''', is a sub-field of analysis that studies such functions (more specifically, '''holomorphic''' functions) on the complex plane, or part (domain) or extension (Riemann surface) thereof.

Drying is one of the oldest methods of food preservation and is used to extend shelf life, reduce microbial activity, and concentrate nutrients. This page provides an overview of dried fruit from a food science and nutritional perspective. == Learning Objectives == By studying this topic, learners should be able to: * Understand what dried fruit is from a scientific perspective * Identify common methods of fruit dehydration * Explain basic nutritional changes during drying * Recognize functional uses of dried fruit in human diet == Processing Methods == Dried fruit is produced using several different techniques: === Sun Drying === A traditional method that relies on natural sunlight and airflow. It is cost-effective but highly dependent on environmental conditions. === Hot Air Drying === A controlled industrial process using heated air circulation. This method provides consistent quality and improved safety standards. === Freeze Drying === A modern dehydration method in which water is removed through sublimation under low temperature and pressure. This method preserves structure and nutrients more effectively but is more expensive. == Nutritional Characteristics == The drying process changes the nutritional profile of fruit in several ways: * Concentration of natural sugars due to water removal * Increased caloric density per gram * Retention of dietary fiber * Partial loss of heat-sensitive vitamins (e.g., vitamin C) Minerals such as potassium, magnesium, and iron generally remain stable during processing. --- == Functional Role in Diet == Dried fruit serves several functional purposes in human nutrition: * Energy-dense natural snack * Alternative to refined sugar-based snacks * Portable food source without refrigeration * Ingredient in bakery and food manufacturing == Common Misconceptions == === Misconception 1: Dried fruit is artificial === Dried fruit is a minimally processed food product derived directly from fresh fruit. === Misconception 2: Dried fruit always contains added sugar === While some commercial products may contain added sugar, many dried fruits are produced without any additives. === Misconception 3: Dried fruit is nutritionally inferior to fresh fruit === Although some vitamins may decrease, fiber and minerals remain largely preserved. == Applications == Dried fruit is used in various contexts: * Food industry ingredients * Healthy snack alternatives * Sports and travel nutrition * Bakery and confectionery products == Further Study == This topic can be expanded into advanced areas such as: * Glycemic response of dried fruits * Behavioral consumption patterns of natural sugars * Food preservation technologies * Nutritional psychology of snack choices == References == * Food science and nutrition textbooks * Peer-reviewed research on dehydration processes * Agricultural and food preservation studies * Nutritional databases (e.g., USDA FoodData Central) == External Links == * Add relevant educational or research links here {{DEFAULTSORT:Introduction to Dried Fruit: Processing, Nutrition, and Functional Overview}} [[Category:Dried fruit]] r3qwcz0c8q09j7x8fjugdl1pp6v9wi9 2816855 2816854 2026-06-26T11:42:22Z AramisDriedFruit 3097189 2816855 wikitext text/x-wiki == Introduction == Dried fruit refers to fruits that have undergone a dehydration process in order to remove most of their water content while preserving their structural components, flavor compounds, and nutritional density.

It is the foundation that guides our exploration of the universe, shapes our perceptions, and directs our pursuits of truth. This essay delves into the significance of reality as the ultimate reference standard and explores its implications across various domains. '''The Nature of Reality''' Reality, often defined as the state of things as they truly exist, constitutes the tangible and measurable aspects of the world. It encompasses both the physical realm, including matter, energy, and natural phenomena, as well as the abstract realm of concepts, ideas, and emotions. While human experiences and [[Finding Common Ground#Perception|perceptions might vary]], the fundamental elements that compose reality remain consistent, forming the bedrock upon which scientific and philosophical inquiries are founded. '''Scientific Pursuit of Truth''' Science, as the systematic exploration of the natural world, heavily relies on reality as the ultimate reference standard. The [[Thinking Scientifically|scientific method]] is centered around empiricism – the process of acquiring knowledge through observation and experimentation. In this pursuit, reality serves as the impartial judge that determines the validity of hypotheses and theories. Scientific discoveries are not validated by personal beliefs or opinions, but by their alignment with the observable and testable aspects of reality. The process of [[w:Peer_review|peer review]], [[w:Peer_review|replication]], and validation by [[Evaluating Evidence|evidence]] underscores the centrality of reality in the scientific community. '''Objective Morality and Ethics''' In the realm of ethics and morality, reality plays a crucial role in defining the foundation of human values. While [[Moral Reasoning|moral frameworks]] and ethical codes may vary across cultures and individuals, they ultimately derive their legitimacy from the inherent truths of [[w:Human_nature|human nature]] and the consequences of actions. Reality provides the basis for understanding the impact of choices on individual [[w:Well-being|well-being]], societal harmony, and the environment. Objective discussions about the consequences of actions become possible only when rooted in the undeniable realities of the world we inhabit. '''Philosophical Reflections''' Reality's significance extends beyond the empirical sciences to [[w:Philosophy|philosophy]], where it serves as the cornerstone of various debates and inquiries. Philosophers often grapple with questions related to the nature of reality, existence, and consciousness. The philosophical exploration of reality encompasses [[w:Ontology|ontological]] debates about the fundamental nature of being, [[w:Epistemology|epistemological]] discussions about knowledge and its limits, and metaphysical inquiries into the nature of reality beyond the observable world. These discussions underline the profound impact that reality has on shaping human thought and understanding. '''Challenges of Perception and Bias''' While reality stands as the ultimate reference standard, human perception and bias can sometimes cloud our understanding of it. Individual experiences, cultural influences, and cognitive biases can lead to misconceptions or distortions of reality. The scientific community acknowledges this challenge by employing rigorous methodologies to minimize the impact of bias and to ensure that observations and measurements accurately reflect the underlying reality. '''Conclusion''' In conclusion, reality occupies a paramount position as the ultimate reference standard that guides human endeavors across scientific, ethical, and philosophical domains. It forms the foundation upon which knowledge is built and serves as the objective measure against which ideas and theories are evaluated. Despite the challenges posed by subjective perceptions and biases, reality remains the bedrock upon which our collective pursuit of truth and understanding is based. As we continue to explore the mysteries of the universe and contemplate the intricacies of existence, it is the unwavering reality that guides us toward deeper insights and a more comprehensive grasp of the world around us.

Swedish is my mother tongue&nbsp;– even though I was born in Finland&nbsp;– but I feel comfortable speaking and writing English and to some extent in German as well. Odd as it may seem, unfortunately I can't speak any Finnish even though I went to school there for a few years prior to moving to Sweden (see [[w:Swedish-speaking population of Finland|Swedish-speaking population of Finland]] in Wikipedia). I've lived all over Sweden but nowadays reside in Uppsala, the fourth biggest city and former capital of Sweden. I'm only the fourth generation named "Kronkvist". My family name consists of two parts: ''kron'' – a short form of the Swedish word ''krona'' meaning 'crown', as in coronation crown or tree crown – and ''kvist'', meaning 'bough' or 'twig'. Hence the name ''Kronkvist'' refers to a twig in the canopy of a forest. I'm the fourth generation of Kronkvist's. Prior to that our family name was ''Mattus'': an oeconym meaning "Matthew's Farm", dating back to at least 1637. {{Clear}} {{User committed identity|a6edd6d2fdbf82621f0cda4e5525c71f8da9b5dfd308242c3c63365e998c32c5406b75448380903265a5403edffd1a0435b61ac943f3c65870db9250f8b884a9|SHA-512|background=#e0e8ff|border=e0e8ff}} tv1kp1foe5ibzik34zfoz3gqbbxm9d4 2 326765 2816834 2816722 2026-06-25T19:04:12Z Dc.samizdat 2856930 /* The 16-cell 4-orthoplex */ 2816834 wikitext text/x-wiki = Golden chords of the 120-cell = {{align|center|David Brooks Christie}} {{align|center|dc@samizdat.org}} {{align|center|Draft in progress}} {{align|center|January 2026 - June 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.

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 5² 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 5² (75) disjoint instances of itself in the 600-point (120-cell), which contains 3² times 5² (225) distinct instances of the 24-point (24-cell), and 3³ times 5² (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

4-orthoplex == In 2-space we have the regular 8-point octagon, in 3-space the regular 8-point cube, and in 4-space the regular 8-point [[16-cell]]. A planar octagon with rigid edges of unit length has chords of length: :<math>r_1=1,r_2=\sqrt{2+\sqrt{2}} \approx 1.848,r_3=\sqrt{2}+1 \approx 2.414,r_4=\sqrt{4 + \sqrt{8}} \approx 2.613</math> The chord ratio <math>r_3=\sqrt{2}+1</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 0.414</math> Note that <math>r_3-2=1/r_3=\sqrt{2}-1</math>. The procedure rotates counterclockwise over three <math>r_3</math> chords of an {8/3} octagram. Over the first <math>r_3</math> chord the displacement is <math>\sqrt{2}+r_1</math>. Over the second <math>r_3</math> chord it moves in the opposite direction a distance of <math>-r_1</math> . Over the third <math>r_3</math> chord it moves a distance of <math>-r_1</math>. If we embed the planar octagon in 3-space, we can make it skew, repositioning its vertices so that each is one unit-edge length distant from three others instead of two others, at the vertices of a unit-edge cube with chords of length: :<math>r_1=1, r_2=\sqrt{2}, r_3=\sqrt{3}, r_4=\sqrt{2}</math> If we embed this cube in 4-space, we can skew it some more, repositioning its vertices so that each is one unit-edge length distant from six others instead of three others, at the vertices of a unit-edge 4-polytope with chords of length: :<math>r_1=1,r_2=1,r_3=1,r_4=\sqrt{2}</math> All of its chords except its long diameters are the same unit length as its edge. In fact they are its 24 edges, and it is a 16-cell of radius <math>1/\sqrt{2}</math>. [[File:octagon16cell.png|thumb|Orthogonal projection of a regular 16-cell to the [[16-cell#Projections|B₄ Coxeter plane]]. Only its edges are shown; its long diameter chords are not drawn. All 24 edges are the same length and none lie parallel to the projection plane. The octagon circumference is a Petrie polygon. The two disjoint squares lie in completely orthogonal central planes. The blue octagram is a Clifford polygon. ]] The [[16-cell]] is the [[W:Regular convex 4-polytope|regular convex 4-polytope]] with [[W:Schläfli symbol|Schläfli symbol]] <small><math>\{3,3,4\}</math></small>. It has 8 vertices, 24 edges, 32 equilateral triangle faces, and 16 regular tetrahedron cells. It is the [[16-cell#Octahedral dipyramid|four-dimensional analogue of the octahedron]], and each of its four orthogonal central hyperplanes is an octahedron. The only planar regular polygons found in the 16-cell are face triangles and central plane squares, but the 16-cell also contains a skew regular octagon, its [[W:Petrie polygon|Petrie polygon]].{{Efn|name=Petrie polygon of a honeycomb}} The chords of this regular octagon, which lies skew in 4-space, are those given above for the 16-cell, as opposed to those for the cube or the regular octagon in the plane. The 16-cell is a construct of 3 Petrie octagons which share the same 8 vertices but have disjoint sets of 8 edges each. The regular octad has higher symmetry in 4-space than it does in 2-space. The 16-cell is the 4-[[w:Cross-polytope|orthoplex]], the simplest regular 4-polytope after the [[5-cell|4-simplex]]. All the larger regular convex 4-polytopes 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 <math>\sqrt{2}</math> edges except opposite pairs. The vertex coordinates of the 16-cell form 6 central squares lying in 6 pairwise [[W:Orthogonal|orthogonal]] coordinate planes. Great squares in opposite planes that do not share an axis (e.g. in the ''xy'' and ''wz'' planes) are completely disjoint (they do not intersect at any vertices). These planes are [[W:Completely orthogonal|completely orthogonal]].{{Efn|name=Six orthogonal planes of the Cartesian basis}} Since the unit-radius coordinate system is convenient, let us derive the unit-radius 16-cell by skewing a unit-radius planar octagon, which has chords of length: :<math>r_1=\sqrt{2-\sqrt{2}} \approx 0.765,r_2=\sqrt{2},r_3=\sqrt{2+\sqrt{2}} \approx 1.848,r_4=2</math> We will need a planar octagon with rigid <math>r_2</math> chords, rather than one with rigid <math>r_1</math> edges. The octagon's <math>r_2</math> chords form two disjoint great squares, visible in the orthogonal projection, which we can reposition in 3-space to form a cube by making them parallel, and in 4-space to form a 16-cell by making them completely orthogonal. Since the edges of the 16-cell are all the same length <math>r_1=\sqrt{2},r_2=\sqrt{2},r_3=\sqrt{2}</math>, those chords are distinct only in the context of a rotation. Each chord is a 4-vector with a length and a direction. The rotational curve over each <math>r_i</math> chord makes <math>i</math> 45° turns. [[File:16-cell-orig.gif|thumb|Orthographic projection of the 8-point 16-cell <small><math>\{3,3,4\}</math></small> performing a double rotation.{{Sfn|Hise|2007}}]] [[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 [[W:SO(4)#Double rotations|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 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 <math>r_1</math> chords of the 16-cell form a Petrie polygon {8/1} which zig-zags back and forth, in the left and right rotational directions, between two completely orthogonal great squares formed by <math>r_2</math> chords. The <math>r_2</math> chords form the ''edge polygon'' of the 16-cell {8/2}=2{4}. The two completely orthogonal great squares lie parallel and perpendicular to each other. A ''simple'' rotation of the 16-cell in ''one'' of those two square central planes rotates that square like a wheel, while the other square does not move.{{Efn|name=simple rotations}} The four vertices of the rotating square orbit on a great circle in the plane. The <math>r_3</math> chords of the 16-cell form a circular helix, visible as a blue {8/3} octagram in the orthogonal projection. A ''double'' rotation of the 16-cell, in both of two completely orthogonal invariant <math>r_2</math> square planes at once by equal angles, moves the eight vertices along the circular helix over the <math>r_3</math> chords. The vertex motion is a [[w:Geodesic|geodesic]] circle orbit on the 3-sphere of a special kind: it does not lie in a central plane, its [[w:Winding_number|winding number]] is not 1 (it is 3 in this case), its circumference is not <math>2\pi</math>, and it moves in either a left or right handed circular spiral. We shall refer to such a chiral circle orbit as an ''isocline'', and to the skew polygram of its rotational chords as a ''Clifford polygon''. The 16-cell is the simplest possible frame in which to [[16-cell#Rotations|observe 4-dimensional rotations]] because its characteristic rotations feature a single pair of invariant rotation planes. In the 16-cell an isoclinic rotation by 90° in any pair of invariant completely orthogonal square central planes takes every great square to its completely orthogonal great square in a twisting displacement, as the invariant planes tilt sideways 90° into each other's plane while rotating 90° internally. All the vertices move at once along the same circular helix geodesic isocline of <math>r_3</math> chords, displaced 90° in 8 orthogonal directions, and the rigid 16-cell assumes a new orientation in 4-space. When the 90° isoclinic rotation is continued in the same rotational direction through an additional 90°, each vertex is again displaced 90°, but from the new orientation in a direction orthogonal to its first 90° displacement. The rotational curve over each 90° <math>r_3</math> chord makes three 45° turns. In 360° of isoclinic rotation over four <math>r_3</math> chords, each vertex makes six 90° turns and reaches its antipodal position. The trajectory of each vertex over each 90° isoclinic rotational displacement is a one-eighth segment of its geodesic orbit. Its entire orbit traces an isocline circle in 4-space of circumference <math>6\pi</math> over eight <math>r_3</math> chords, and also traces an ordinary great circle in the plane twice, over the four <math>r_2</math> edges of a great square in one of the two moving invariant rotation planes. In the course of a 720° isoclinic revolution 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. Because this is the isoclinic rotation of the 16-cell in its invariant great circle edge planes we shall refer to it as the ''great square right rotation characteristic of the 16-cell'', and note once again that it is Fontaine and Hurley's rotation over the <math>r_3</math> star polygon, which constructs <math>1/r_3</math>. == The 8-cell tesseract == The long diameter of the unit-edge [[W:Hypercube|hypercube]] of dimension <math>n</math> is <math>\sqrt{n}</math>, 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 [[w:Cuboctahedron|cuboctahedron]] and the 24-cell are also radially equilateral. [[File:8-cell.gif|thumb|Orthographic projection of the 16-point (8-cell) tesseract <small><math>\{4,3,3\}</math></small> performing a simple rotation about a plane in 4-space.{{Sfn|Hise|2007}} The stationary plane bisects the figure from front-left to back-right and top to bottom.]] The [[W:Tesseract|tesseract]] is the [[W:Regular convex 4-polytope|regular convex 4-polytope]] with [[W:Schläfli symbol|Schläfli symbol]] <small><math>\{4,3,3\}</math></small>. It has 16 vertices, 32 edges, 24 square faces, and 8 cube cells. It is the four-dimensional analogue of the cube. 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 4-point regular tetrahedra]]. The [[W:Demihypercube|demihypercubes]] occupy alternate vertices of the hypercubes. The diagonals of the square faces of the unit-edge, unit-radius tesseract are the <math>\sqrt{2}</math> edges of two unit-radius 16-cells, also the edges of the square central planes. We can rotate the tesseract isoclinically the way we rotated the 16-cell, by 90° in the great square right rotation, with the same effect on both alternate-position 16-cells. In the course of a 720° revolution 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 two skew {8/3} octagram Clifford polygons lie on two disjoint parallel isoclines of the same chirality, of circumference <math>6\pi</math> over <math>\sqrt{2}</math> chords. They form a circular double helix which intersects each vertex of the tesseract once. The tesseract is the [[W:Dual polytope|dual polytope]] of the 16-cell. They have the same Petrie polygon, the regular skew octagon, but the tesseract is a construct of 4 Petrie octagons with disjoint sets of 8 tesseract edges each. We can construct the tesseract by skewing two planar octagons. Because the tesseract is radially equilateral (unlike the 16-cell), we use two octagons of unit-edge length to build the unit-radius tesseract. To start we embed the planar octagons in 4-space at the same point and make them completely orthogonal. Then we skew each planar octagon into a cube, so we have a compound of two completely orthogonal cubes, provided we skewed them both in the same direction. The 16 vertices will be the vertices of a tesseract with half its 32 edges missing. 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 square central 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. Otherwise they are 0° apart in one of the angles, 90° apart by simple rotation, 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.|name=simple rotations}} A pair of square central planes from alternate-position 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-position 16-cells' corresponding square central planes, but also the 16-cells themselves, are Clifford parallel objects. More generally, multiple disjoint instances of a 4-polytope which compound to make a larger 4-polytope are Clifford parallel objects. == The 24-cell == [[File:24-cell vertex geometry.png|thumb|Planar geometry of the radially equilateral 24-cell, showing its 3 great circle polygons and its 4 chord lengths.]] 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 12 cuboctahedron central hyperplanes and 16 hexagonal central planes. The [[24-cell]] is the regular convex 4-polytope with Schläfli symbol <small><math>\{3,4,3\}</math></small>. It has 24 vertices, 96 edges, 96 equilateral triangle faces, and 24 octahedron cells. It is the four-dimensional analogue of the cuboctahedron.

It is the maximal regular construct of triangles and squares (with no pentagons). It is the convex hull of a compound of three disjoint 8-point 16-cells, rotated 60° isoclinically with respect to each other. Each of the three pairs of 16-cells is a tesseract. Each 24-cell edge is also a tesseract edge. The corresponding vertices of two 16-cells or two tesseracts are 120° apart by a <math>\sqrt{3}</math> chord. Each tesseract has 8 cube cells, and each cube has four <math>\sqrt{3}</math> long diameters. The <math>\sqrt{3}</math> chords joining the corresponding vertices of two tesseracts belong to the third tesseract as cell long diameters. The 24-cell's Petrie polygon is the regular dodecagon {12}, which has chords: :<math>r_1=\tfrac{\sqrt{3}-1}{\sqrt{2}} \approx 0.518,r_2=\sqrt{1},r_3=\sqrt{2},r_4=\sqrt{3},r_5=\tfrac{\sqrt{3}+1}{\sqrt{2}} \approx 1.932,r_6=\sqrt{4}</math> Fontaine and Hurley's procedure for obtaining the reciprocal of a chord tells us that: :<math>r_5-r_3+r_1+r_1-r_3=1/r_5</math> when <math>r_1=1</math>. The procedure rotates counterclockwise over five <math>r_5</math> chords of a {12/5} dodecagram. In the system of unit-radius coordinates <math>r_1=1/r_5</math>.

In 720° 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-cells. The rotational curve over each 90° chord makes three 45° turns. Three Clifford parallel {8/3} octagram geodesic isoclines of circumference <math>6\pi</math> form a circular triple helix {24/9}=3{8/3} that intersects each 24-cell vertex once. [[File:Regular star figure 2(12,5).svg|thumb|left|150px|{24/10}=2{12/5} <small><math>\sqrt{3}</math></small> ]] We can rotate the 24-cell isoclinically in 4 Clifford parallel invariant great hexagon planes containing its <math>r_{2}</math> edges, over <math>r_{5}=\sqrt{3}</math> isocline chords. This is the ''great hexagon right rotation characteristic of the 24-cell'', also Fontaine and Hurley's rotation over the <math>r_5</math> star polygon which constructs <math>1/r_5</math>. A complete hexagon right revolution requires 720° like a complete square right revolution, but it is completed in 12 isoclinic displacements of 60° each rather than 8 isoclinic displacements of 90° each. The rotational curve over each 120° <math>r_5</math> chord makes five 30° turns. Two Clifford parallel {12/5} dodecagram geodesic isoclines of circumference <math>10\pi</math> over <math>r_5</math> chords form a circular double helix {24/10}=2{12/5} that intersects each 24-cell vertex once. In the 24-cell a great hexagon right rotation by 60° in any invariant hexagon central plane takes every great hexagon to a Clifford parallel great hexagon in a twisting displacement, as all the central planes tilt sideways 60° while rotating 60° internally. It also takes every great square to a Clifford parallel great square in another 16-cell; it takes every 16-cell to another 16-cell. The 16-cells revolve within the 24-cell as well as rotating within it. All 24 vertices move at once on two Clifford parallel geodesic isoclines, displaced 120° in different directions. The trajectory of each vertex over each 60° rotational displacement is a one-twelfth segment of its geodesic orbit. Its entire orbit traces an isocline circle in 4-space of circumference <math>10\pi</math> over twelve <math>\sqrt{3}</math> chords, and also traces an ordinary great circle in the plane twice, over the six <math>\sqrt{1}</math> edges of a great hexagon in a moving invariant rotation plane. In the course of a 720° right revolution each vertex departs from 12 vertex positions just once and returns to its original position, and the 24-cell returns to its original orientation. == The 600-cell == [[Image:600-cell.gif|thumb|Orthographic projection of the 120-point 600-cell <small><math>\{3,3,5\}</math></small> performing a simple rotation.{{Sfn|Hise|2011}} The 3-dimensional surface made of 600 tetrahedra is visible.

It has 120 vertices, 720 edges, 1200 equilateral triangle faces, and 600 tetrahedron cells. It is the four-dimensional analogue of the icosahedron. The 600-cell rounds out the 24-cell by adding 96 more vertices (four more disjoint 24-cells) between the 24-cell's existing 24 vertices, in effect adding twenty-four more distinct 24-cells inscribed in the 600-cell. The new surface thus formed is a honeycomb of smaller, more numerous cells: tetrahedra of edge length <math>\phi^{-1} \approx 0.618</math> instead of octahedra of edge length <math>\sqrt{1}</math>. It encloses the <math>\sqrt{1}</math> edges of the 24-cells, which become invisible interior chords in the 600-cell, like the <math>\sqrt{2}</math> and <math>\sqrt{3}</math> chords. Since the tetrahedra are made of shorter triangle edges than the octahedra (by a factor of <math>\phi^{-1}</math>, the inverse golden ratio), the 600-cell is not radially equilateral like the 24-cell and the tesseract. Like them it is radially triangular in a special way, but one in which [[w:Golden_triangle_(mathematics)|golden triangles]] rather than equilateral triangles meet at the center. In 2-space we have the ''radially golden'' [[W:Decagon#The golden ratio in decagon|regular decagon]]. In 3-space we have the radially golden 30-point [[W:icosidodecahedron|icosidodecahedron]], with 6 decagon central planes. In 4-space we have the radially golden 120-point 600-cell, with 60 icosidodecahedron central hyperplanes and 72 decagon central planes.

This table first appears in [[w:Regular_Polytopes_(book)|''Regular Polytopes'']] (1947),{{Sfn|Coxeter|1973|loc=Table V(v): Simplified sections of {5,3,3} beginning with a vertex|pp=300-301}} where Coxeter identified each row with a distinct [[w:120-cell#Concentric_hulls|polyhedral section of the 120-cell]] beginning with a vertex. In spherical [[w:3-sphere|3-dimensional space <math>\mathbb{S}^3</math>]], every vertex is the center of a set of 29 concentric polyhedra of increasing radii that nest like [[w:Matryoshka_doll|Russian dolls.]] The smallest polyhedral section at radial distance <math>c_1</math> is a tetrahedron vertex figure, and the largest section at radial distance <math>c_{15}</math> is a central section bisecting the 120-cell. Because [[w:3-sphere|<math>\mathbb{S}^3</math>]] is spherical, at radial distances greater than <math>c_{15}</math> the successive complement-radius polyhedra decrease in size, to the antipodal tetrahedron vertex figure at distance <math>c_{29}</math>. In Euclidean 4-dimensional space <math>\mathbb{R}^4</math>, every vertex is the apex of 29 [[w:Hyperpyramid|polyhedral pyramids]], where the pyramid's lateral edge length is the radial distance and its base polyhedron is the section. Each section lies parallel to a congruent complement-radius section (or coincident with it, in the case of the central section). Each section also lies completely orthogonal to a congruent section. Only 8 of the 30 chords in the table occur in the 600-cell and the planar {30)-gon. The 120-cell's additional chords arise originally from the regular 5-cell, in its interaction with the other regular 4-polytopes that compound to make the 120-cell. Since all those polytopes except the 5-cell occur in the 600-cell, and the 600-cell and the 120-cell have the same symmetry group, the 5-cell's symmetry group is what's new in the 120-cell. ... {{Clear}} == Finally the 120-cell == The [[120-cell]] is the regular convex 4-polytope with Schläfli symbol <small><math>\{5,3,3\}</math></small>. It has 600 vertices, 1200 edges, 720 pentagon faces, and 120 dodecahedron cells. It is the four-dimensional analogue of the dodecahedron. The 120-cell is the [[W:Dual polytope|dual polytope]] of the 600-cell. They have the same Petrie polygon, the regular skew triacontagon {30}, but the 120-cell is a construct of 40 Petrie {30}-gons of edge length <math>c_1</math>, two of which intersect in each tetrahedral vertex figure. ... {{Clear}} == Conclusions == Fontaine and Hurley's discovery is more than a geometric formula for the reciprocal of a regular ''n''-polygon diagonal. It also yields the discrete sequence of isocline chords of the characteristic isoclinic rotation of a ''d''-dimensional polytope in its invariant edge planes. 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. [If what is meant by this is its Petrie polygon, it is not quite necessary or possible with respect to the planar polygon chords, e.g. the planar Petrie polygon of the 600-cell does not contain the <math>\sqrt{2}</math> chord. But perhaps it would work if the fit is to the smallest regular skew polygon in the ''d''-space.] The discovery of a chordal construction for discrete isoclinic rotations generally 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 the 120-cell demonstrates why the connection exists: because polytope sequences generally, from Steinbach's golden chord sequences in polygons, to sequences of star polygons in isoclinic rotations, 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}} 87n1lm1bizjeysqnfd2g37to5x1s2bs 0 329511 2816853 2811096 2026-06-26T08:44:49Z MNTPicker 3070751 /* The Migration to Bengal */ 2816853 wikitext text/x-wiki {{history}} [[File:Oil Portrait of Maharaja Virendra Mohan Dar of Akhnoor.jpg|thumb|Claude-Sterling Oil Portrait of Maharaja Virendra Mohan Dar of Akhnoor- ''The Maharaja at 26'']] == Maharaja Virendra Mohan Dar - Founder of the Dar Raj == [[W:Maharaja|Maharaja]] Virendra Vasudev Mohan Dar, otherwise known as the effective founder of the Dar Raj's political and ceremonial standing, was born on Thursday, the 14th of September 1758, in the ancestral quarters of the Akhnoor region of Kashmir. He was the eldest son of Ram Hari Mohan Dar and Smt. Annapurna Devi, the third daughter of the esteemed merchant Pandit Narayan Kaul of Srinagar. His lineage traces back to his grandfather, Hari Krishna Mohan Dar (1687–1768), a saffron merchant and learned Kashmiri Pandit who established the family’s zamindari foundations in the late 17th century. From his earliest years, Virendra exhibited a discerning mind and a keen disposition for learning. He was educated under several specialized tutors: Pandit Madhusudan Kaul (classical literature, Sanskrit, Persian, and land management), Pandit Gopesh Raina (arithmetic, accounts, and revenue management), and Pandit Jagannath Bhat (Durrani administrative customs and local jurisprudence). By the age of ten, he was already distinguished for his recitals of historical and sacred texts, and by seventeen, he was accompanying his father on tours of the family's vast estates in both Kashmir and Bengal, including Dhamrai and Char Talibari == Accession and the Title of Maharaja == Upon the death of his father in 1778, Virendra Mohan Dar assumed full responsibility for the administration of the Dar Raj estates.His accession occurred during a period of significant political flux as the [[wikipedia:Durrani Empire|Durrani Empire]] consolidated power in the Punjab and Kashmir. In 1771, following his judicious resolution of disputes among neighboring zamindars, the court of [[wikipedia:Ahmad Shah Durrani|Ahmad Shah Durrani]] conferred upon him the prestigious hereditary title of "Maharaja". The formal investiture took place, in the autumn of 1771 in the principal hall of the Akhnoor estate.The Maharaja was presented with robes of state and a ceremonial sword, and he pledged to govern with fairness and diligence. To consolidate his authority, he convened a formal Assembly of Zamindars at Akhnur in 1771 to settle boundary disputes and restate revenue obligations. He was known for a "calculated exercise of power," notably seen in 1782 when he resolved a case of revenue defiance through public inquiry and surveyors rather than armed force == The Migration to Bengal == By the late 18th century, the political stability of the northern territories declined. Provincial governors began prioritizing immediate revenue extraction, and the Akhnoor holdings faced increasing pressure from irregular levies and armed groups associated with local power brokers. In response, the Maharaja implemented a strategic reorientation, gradually shifting the center of his administration to the fertile and more stable plains of [[W:Bengal|Bengal]]. This transition was finalized by a natural calamity in the late 1790s. An exceptionally severe flooding of the [[W:Padma River|Padma River]] resulted in the rapid submergence of the Char Talibari estate, erasing established boundaries and rendering the former seat uninhabitable. Consequently, in 1801, the Maharaja established the Nannar Rajbari (later known as the Dhar Zamindar Bari) in the Dhamrai region. The new residence featured thick brick walls bound with lime-surki mortar and included the Maharaja Virendra Sagar, a large reservoir providing water for both the household and local irrigation. == Courtly Life and Administration == Courtly life at Nannar was governed by a disciplined structure, distinguishing between public functions in the outer courts and private life in the inner quarters. Daily routines included administrative sessions where estate officers presented accounts of cultivation and revenue. The Maharaja was known to dress in fine muslin and silk robes, and the meals served at court reflected a blending of both Kashmiri and Bengali culinary influences The administration of the Bengal estates—including villages such as ''Rajrajeshwar'', ''Rowail'', ''Sharifbagh'', and ''Ashulia''—was conducted with diligence. The Maharaja personally inspected irrigation works and canals, ensuring that the welfare of the cultivators was protected. == Later Years and Succession == In his later years, the Maharaja withdrew from daily arduous labor but remained steadfast in his supervision of revenue and justice. In 1820, his health began to decline due to a malady of the stomach. Maharaja Virendra Mohan Dar passed away on the 3rd of February, 1821, at the age of sixty-two. The legacy of the Dar Raj was carried forward by his sons, Raja Mukund Mohan Dar and Bhupendra Mohan Dhar. His lineage continued to produce distinguished figures, including Rai Bahadur Hara Mohan Dhar (a barrister of the Middle Temple), Justice Mohini Mohan Dhar, Judge and former Dewan of Mayurbhanj, Satyendra Mohan Dhar, C.I.E.

If they don't respond, it's clear that there's no point in waiting any longer and their rights have been revoked. On the contrary, if they respond, they suspect that they should start working on Wikiversity, but it may happen that they won't, i.e. SSM will respond, but they will continue to be inactive, so they will have another year of "peace". I would probably reduce the inactivity time to '''8 months''' (i.e. 6 months + 2 months, which may take to creat a custodian), but I would leave the response time at a '''month or more'''. I assume that sometimes the reason for inactivity is health problems or personal problems, and in such situations a person is usually not very reactive - i.e. they don't manage to respond quickly to all the requests that come to them. Another reason may be the busy work schedule of university teachers, who, for example, are on the job for 4 months during exams. This means, yes, you have been inactive for a while for some reason and then someone invites you to return to activity, but you are sick, or you are writing a scientific article, grant report, etc. and you don't have much time right now. Here, it would perhaps require standardized posts for all SSM roles, where a notice would be written that according to the policy, a SSM cannot be inactive for a given period. ''Then a question whether they will resume activity within 2 months.'' Yes - rights retained, no/no answer - rights removed within a month.

I would probably reduce the inactivity time to '''8 months''' (i.e. 6 months + 2 months, which may take to creat a custodian), but I would leave the response time at a '''month or more'''. I assume that sometimes the reason for inactivity is health problems or personal problems, and in such situations a person is usually not very reactive - i.e. they don't manage to respond quickly to all the requests that come to them. Another reason may be the busy work schedule of university teachers, who, for example, are on the job for 4 months during exams. This means, yes, you have been inactive for a while for some reason and then someone invites you to return to activity, but you are sick, or you are writing a scientific article, grant report, etc. and you don't have much time right now. Here, it would perhaps require standardized posts for all SSM roles, where a notice would be written that according to the policy, a SSM cannot be inactive for a given period. ''Then a question whether they will resume activity within 2 months.'' Yes - rights retained, no/no answer - rights removed within a month.

In the ethnographic work of the anthropologist M.M. Green in Igboland, he documented women in 1947 wearing festive headcloths to market and observed that headcloths were commonly worn at meetings and social gatherings as part of their clothing ensemble.<ref name=":13" /> Igbo headtie is worn in a big, bold and stylish manner with flared ends using vibrant fabrics measuring six by three feet in size. Writing about her experiences in Igboland, Rhoda Cowen described Igbo headtie referred to as Ichafo and Icafo as a big brightly colored headdress worn in a bold and stylish manner noting that some were wrapped around the head with projecting ends, while others formed striking elements of women's attire alongside vibrant colored fabrics or textiles and gold jewellery.<ref name=":12" /> Igbo headtie has also been recorded in ethnographic studies of Igbo dress as a headgear fashioned from a decorative piece of cloth worn around the head known as Ichafo. It is fashioned from a piece of cloth approximately six by three feet in size, folded into triangular or rectangular forms and wrapped around the head in an elevated manner that creates a style resembling a tall turban with decorative bow. According to the author, a headgear is distinguished from a head-tie which is smaller and worn flat around the head in the Nigerian context while defining Igbo style of headtie as a headgear.<ref name=":9" /> === Helmet coiffures and beaded crowns === Igbo headdresses also include elaborate female head adornments, as well as decorative headgear featuring elaborate coiffures worn by masquerades such as the ''Agbogho Mmuo'' (maiden spirit) during festivals and cultural events.

Some were built on a foundation of clay, charcoal and palm oil and moulded into a crest resembling the central ridge of a Roman helmet, extending from the forehead to the nape of the neck.

Studies of present-day Igbo dress culture depict the brides and her maidens wearing beaded crowns as part of the traditional attire, or decorate their hair with bead accessories during weddings and Cultural celebrations.

This historic site is one of the most significant landmarks representing the grandeur of the Bengali aristocracy during the British colonial era. == History == [[File:Oil Portrait of Maharaja Nabakrishna Deb and Attendee.png|thumb|Oil Portrait of Maharaja Nabakrishna Deb Bahadur]] The lineage was founded by Maharaja Nabakrishna Deb (b.1733 – d.1797). Starting as a modest aristocrat, he amassed significant wealth and influence through his service to the British East India Company, most notably his role as a confidential secretary and negotiator for Robert Clive during the period surrounding the Battle of Plassey (c. 1757). The family is widely recognized for: * '''The Bengal Renaissance:''' The family played a key role in patronizing the intellectual and cultural movements of 19th-century Bengal. * '''Cultural Patronage:''' The residence became a focal point for social and cultural gatherings, hosting luminaries such as Raja Ram Mohan Roy, Rabindranath Tagore, and Swami Vivekananda. * '''Durga Puja:''' In 1757, following the victory at Plassey, Maharaja Nabakrishna Deb initiated the tradition of the grand Durga Puja at the Rajbari, a practice that continues to draw thousands of visitors annually. == The Sovabazar royal family == [[File:Radhakanta Deb-রাধাকান্ত দেব Academic Oil Portrait.png|thumb|Raja Radhakanta Deb of Sovabazar]] The royal clan begins with Maharaja Nabakrishna Deb Bahadur, who left behind two sons, the adopted son Raja Gopimohan Deb (b. 1768) and his own son Raja Raj Krishna Deb. Raja Gopimohan Deb was founder director of Hindu College and founder of famous Dharma Sabha. His son was Radhakanta Deb, whereas Raja Rajkrishna Deb (b.1782 – d.1823) had eight sons. * Shiv Krishna * Kali Krishna * Debi Krishna * Apurbo Krishna Kunvar * Kamal Krishna * Madhab Krishna * Narendra Krishna Deb == The Palaces == [[File:Sovabazar boro Rajbari thakurdalan at Sovabazar area of North Kolkata 01.jpg|thumb|Sovabazar Palace- Seat of Sovabazar royal family]] The family estate consists of two main structures on Raja Nabakrishna Street, both showcasing a blend of traditional Bengali and European architectural styles: === The Main Palace (35 Raja Nabakrishna Street) === Often called ''"Baag ola Bari"'' (House with the Lions), this is the older structure.

This historic site is one of the most significant landmarks representing the grandeur of the Bengali aristocracy during the British colonial era. == History == [[File:Oil Portrait of Maharaja Nabakrishna Deb and Attendee.png|thumb|Oil Portrait of Maharaja Nabakrishna Deb Bahadur]] The lineage was founded by Maharaja Nabakrishna Deb (b.1733 – d.1797). Starting as a modest aristocrat, he amassed significant wealth and influence through his service to the British East India Company, most notably his role as a confidential secretary and negotiator for Robert Clive during the period surrounding the Battle of Plassey (c. 1757). The family is widely recognized for: * '''The Bengal Renaissance:''' The family played a key role in patronizing the intellectual and cultural movements of 19th-century Bengal. * '''Cultural Patronage:''' The residence became a focal point for social and cultural gatherings, hosting luminaries such as Raja Ram Mohan Roy, Rabindranath Tagore, and Swami Vivekananda. * '''Durga Puja:''' In 1757, following the victory at Plassey, Maharaja Nabakrishna Deb initiated the tradition of the grand Durga Puja at the Rajbari, a practice that continues to draw thousands of visitors annually. == The Sovabazar royal family == [[File:Radhakanta Deb-রাধাকান্ত দেব Academic Oil Portrait.png|thumb|Raja Radhakanta Deb of Sovabazar]] The royal clan begins with Maharaja Nabakrishna Deb Bahadur, who left behind two sons, the adopted son Raja Gopimohan Deb (b. 1768) and his own son Raja Raj Krishna Deb. Raja Gopimohan Deb was founder director of Hindu College and founder of famous Dharma Sabha. His son was Radhakanta Deb, whereas Raja Rajkrishna Deb (b.1782 – d.1823) had eight sons. * Shiv Krishna * Kali Krishna * Debi Krishna * Apurbo Krishna Kunvar * Kamal Krishna * Madhab Krishna * Narendra Krishna Deb == The Palaces == [[File:Sovabazar boro Rajbari thakurdalan at Sovabazar area of North Kolkata 01.jpg|thumb|Sovabazar Palace- Seat of Sovabazar royal family]] The family estate consists of two main structures on Raja Nabakrishna Street, both showcasing a blend of traditional Bengali and European architectural styles: === The Main Palace (35 Raja Nabakrishna Street) === Often called ''"Baag ola Bari"'' (House with the Lions), this is the older structure. It served as the primary residence and is known for its: * '''Nat Mandap:''' An open-air pavilion used for religious festivals and cultural performances. * '''Courtyard Architecture:''' A classic ''saat-khilan'' (seven-arched) thakurdalan with intricate multifoil arches. === The Choto Rajbari (33 Raja Nabakrishna Street) === Built by Nabakrishna Deb for his biological son, Raja Rajkrishna Deb, this structure is smaller but equally significant in the history of the family’s legacy. == Architectural Features == The architecture is categorized as a "hybrid" style, common among the *Bonedi Bari* (aristocratic mansions) of Kolkata.

In addition, we suppose that <math>a</math> is different from zero, otherwise the equation would be linear. First, we compute the determinant <math>\Delta = b^2 - 4 a c</math>. We distinguish three cases: If the determinant is positive, then equation admits two solutions: <math> x_{1,2} = \frac{-b \pm \sqrt{\Delta}}{2 a} </math> If the determinant is zero, then equation admits the single solution: <math> x = \frac{-b}{2 a} </math> If the determinant is negative, there are no real value satisfying the quadratic equation. === Example: === Solve <math>2x^2 - 8x + 6 = 0</math> for <math>x</math>. The determinant is, <math> \Delta = b^2 - 4 a c = 8^2 - 4 \cdot 2 \cdot 6 = 16 </math> The equation admits therefore two solutions, namely: <math> x_{1,2} = \frac{8 \pm \sqrt{16}}{2 \cdot 2} = \frac{8 \pm 4}{4} = 2 \pm 1 </math> The two solutions are thus <math>x_{1} = 1</math> and <math>x_{2} = 3</math> (the order is not important). ==== Verification ==== Indeed, this can be verified substituting <math>x_1</math> and <math>x_2</math> in the original equation: <math> 2 \cdot 1^2 - 8 \cdot 1 + 6 = 2 - 8 + 6 = 0 </math> and <math> 2 \cdot 3^2 - 8 \cdot 3 + 6 = 18 - 24 + 6 = 0 </math> ==== Alternative solution ==== The equation can also be solved by "completing the square''":'' <math>2x^2 - 8x + 6 = 0</math> Divide by 2 so that <math>x^2</math> is alone: <math>x^2 - 4x + 3 = 0</math> Subtract <math>3</math> <math>x^2 - 4x = -3</math> We want to apply the binomial formula <math>x^2 + 2 x y + y^2 = (x+y)^2</math> on the left side of the equation. If <math>-4x</math> is <math>2 x y</math>, then <math>y</math> is <math>-2</math> and <math>y^2</math> is <math>4</math>: <math>x^2 - 4x + 4 = -3 + 4</math> Apply the binomial formula: <math>(x - 2)^2 = -3 + 4</math> Or <math>(x - 2)^2 = 1</math> Let's take the square root: <math>x - 2 = \pm 1</math> Solve for <math>x</math> <math>x = 2 \pm 1</math> The solutions are thus <math>1</math> and <math>3</math>. The previous approach can be uses to proof the general formula. n3js5do6tqn624z1j4p3uztf53v0gao 0 330345 2816836 2026-06-25T20:22:40Z DavidMCEddy 218607 create 2816836 wikitext text/x-wiki :''This discusses a 2026-07-02 interview with [[w:Robert Corn-Revere|Robert Corn-Revere]] about the [[w:Foundation for Individual Rights and Expression|Foundation for Individual Rights and Expression]] (FIRE), including a video and 29:00 mm:ss podcast excerpted from the interview.

Corn-Revere has appeared on multiple lists of best lawyers since 2017. Some of his expertise is summarized in his (2021) ''The Mind of the Censor and the Eye of the Beholder : the First Amendment and the Censor's Dilemma'', building on his extensive research and experience including three earlier books.<ref>Corn-Revere, ed. (1997), Corn-Revere (1998), Zuckman et al.

He began with, :''We live in interesting times.'' === Interesting times === He then noted that the "ancient Chinese curse, '[[w:May you live in interesting times|May you live in interesting times]]'" is ''not'' Chinese: It has been traced to Austin Chamberlain, brother of the British Prime Minister, [[w:Neville Chamberlain|Neville Chamberlain]]. Corn-Revere mentioned a vaguely related Chinese aphorism, that it is "Better to be a dog in times of tranquility than a human in times of chaos." He then said, "Some days, when I look at our two [[w:Australian Shepherd|Australian Shepherd]]s, [[w:Lenny Bruce|Lenny and Bruce]], and think I wouldn't mind trading places."<ref>Should we be surprised that a [[w:First Amendment to the United States Constitution|First Amendment]] lawyer would name his dogs after a comedian famously prosecuted for obscenity?</ref> === Learned Hand: "Liberty lies in the hearts of men and women" === He praised [[w:Learned Hand|Learned Hand]], who issued more than 3,000 legal opinions in his 52 years as a US federal judge, which as of 2014 had reportedly been quoted more often than those of any other US judge who had not served on the Supreme Court. He rose to fame outside the legal profession after describing "The Spirit of Liberty" to a crowd of 150,000 newly naturalized US citizens 1944-05-21. Hand said, {{quote| Liberty lies in the hearts of men and women; when it dies there, no constitution, no law, no court can save it; no constitution, no law, no court can even do much to help it.}} === A culture of free expression === Corn-Revere said we need a culture of free expression. {{quote| [I]it is essential to provide breathing space for all points of view, even for those we detest. perhaps ''especially'' for those we detest.}} He quoted Justice [[w:Oliver Wendell Holmes Jr.|Holmes]] from a 1929 dissent that supported the "principle of free thought — not free thought for those who agree with us but freedom for the thought that we hate." === FIRE's business Model === Corn-Revere continued that FIRE's president, [[w:Greg Lukianoff|Greg Lukianoff]], has been told they have "a terrible business model, because it guarantees we are going to annoy every faction in American politics at one point or another. ... We take it as a point of pride. ... The corollary to our motto {{quote| If it is protected, we will defend it}} is this: {{quote| If you are a censor, we will fight you.}} === Free speech is the best and perhaps only way to resolve disputes without violence or coercion === Corn-Revere continued, claiming that free speech is the best and perhaps only way to resolve disputes without violence or coercion. We try "to remind people that there is a possibility they might not be right about everything." Judge Hand said that the spirit of liberty “is not too sure that it is right." Former Justice [[w:Anthony Kennedy|Anthony Kennedy]] described the flip-side of this concept. “Self-assurance,” he wrote, “has always been the hallmark of a censor.” A mind filled with certainty is a closed mind. Corn-Revere continued, {{quote| I think for most issues, you are more likely to be persuasive if your objective isn’t to explain to someone why they are dead wrong. Maybe it is enough just to learn a little more about why you disagree. ... [D]ialogue is the beginning of finding a peaceful resolution of any problem. ... I believe the era we are living through now will make us stronger still. ... [W]e went through the [[w:First Red Scare|Red Scare of 1919]], World War II, the [[w:McCarthyism|McCarthy Era]], the [[w:Civil rights movement|civil rights]] and [[w:Opposition to United States involvement in the Vietnam War|antiwar demonstrations]] of the 60s and 70s, and since then an upheaval in the technology of how we communicate. Each was seen at the time as an existential crisis. ... Is success guaranteed? No, of course not, and it never was. What is certain is that history is written by those who stand up, not by those who bend the knee to temporary power. ... [F]or those who find themselves confronted with frivolous litigation brought by figures of great influence, it means not settling what you know to be meritless claims. Doing so may at the time seem expedient and even rational. But ... it represents short-term thinking. If you doubt this, just ask the law firms targeted with executive orders who settled with the administration, as distinguished from those who stood on their rights.}} == The need for media reform to improve democracy == This article is part of [[:category:Media reform to improve democracy]].
