Sym. Triangle: V = 1/24(a-b)^2

proving that probability metrics satisfy triangle inequality
Neither the original paper nor the wikipedia page prove that the introduced probability metrics are guaranteed to satisfy triangle inequality constraints. Any leads on that?

If you have a close connection to some of the people, places or things you have written about, you may have a conflict of interest. In keeping with Wikipedia's neutral point of view policy, edits where there is a conflict of interest, or where such a conflict might reasonably be inferred from the tone of the edit and the proximity of the editor to the subject, are strongly discouraged. If you have a conflict of interest, you should avoid or exercise great caution when:
 * 1) editing or creating articles related to you, your organization, or its competitors, as well as projects and products they are involved with;
 * 2) participating in deletion discussions about articles related to your organization or its competitors; and
 * 3) linking to the Wikipedia article or website of your organization in other articles (see Spam).

Please familiarize yourself with relevant policies and guidelines, especially those pertaining to neutral point of view, verifiability of information, and autobiographies.

For information on how to contribute to Wikipedia when you have conflict of interest, please see our frequently asked questions for organizations.

Hi there
Firstly, congrats on your PhD! Friend of mine did one on graph theory - not that I could ever understand what he was working on. There are a couple of possibilities mentioned on the AfD page of ways we could resolve this problem without losing your very valuable expert contributions. See what you think. All the best Tim Vickers (talk) 21:11, 5 June 2009 (UTC)

Agnieszka Gortel
Hi! It seems you recently created an unreferenced biography of a living person: Agnieszka Gortel. The community has decided that all new biographies of living persons must contain a reliable source that supports at least one statement made about the person in the article as per our verifiability policy. Please add references as soon as possible. Thanks! --LaraBot (talk) 00:10, 30 June 2010 (UTC)

Speedy deletion nomination of Agnieszka Gortel


A tag has been placed on Agnieszka Gortel requesting that it be speedily deleted from Wikipedia. This has been done because the article, which appears to be about a real person, individual animal(s), an organization (band, club, company, etc.), or web content, does not indicate how or why the subject is notable: that is, why an article about that subject should be included in an encyclopedia. Under the criteria for speedy deletion, articles that do not indicate the subject's importance or significance may be deleted at any time. Please see the guidelines for what is generally accepted as notable. If this is the first page that you have created, then you should read the guide to writing your first article.

If you think that you can assert the notability of the subject, you may contest the deletion by adding  to the top of the article (just below the existing speedy deletion or "db" tag - if no such tag exists then the page is no longer a speedy delete candidate and adding a hangon tag is unnecessary), coupled with adding a note on the article's talk page explaining your position, but be aware that once tagged for speedy deletion, if the article meets the criterion it may be deleted without delay. Please do not remove the speedy deletion tag yourself, but don't hesitate to add information to the article that would confirm the subject's notability under Wikipedia guidelines.

For guidelines on specific types of articles, you may want to check out our criteria for biographies, for web sites, for bands, or for companies. Feel free to leave a note on my talk page if you have any questions about this. Active Banana (talk) 00:28, 30 June 2010 (UTC)

Proposed deletion of Agnieszka Gortel


The article Agnieszka Gortel has been proposed for deletion because under Wikipedia policy, all biographies of living persons created after March 18, 2010, must have at least one source that directly supports material in the article.

If you created the article, please don't take offense. Instead, consider improving the article. For help on inserting references, see Referencing for beginners or ask at Help desk. Once you have provided at least one reliable source, you may remove the prod blp tag. Please do not remove the tag unless the article is sourced. If you cannot provide such a source within ten days, the article may be deleted, but you can request that it be undeleted when you are ready to add one.

Notification: changes to "Mark my edits as minor by default" preference
Hello there. This is an automated message to tell you about the gradual phasing out of the preference entitled "Mark all edits minor by default", which you currently have (or very recently had) enabled.

On 13 March 2011, this preference was hidden from the user preferences screen as part of efforts to prevent its accidental misuse (consensus discussion). This had the effect of locking users in to their existing preference, which, in your case, was. To complete the process, your preference will automatically be changed to  in the next few days. This does not require any intervention on your part and you will still be able to manually mark your edits as being 'minor'. The only thing that's changed is that you will no longer have them marked as minor by default.

For established users such as yourself there is a workaround available involving custom JavaScript. If you are familiar with the contents of WP:MINOR, and believe that it is still beneficial to the encyclopedia to have all your edits marked as such by default, then this discussion will give you the details you need to continue with this functionality indefinitely. If you have any problems, feel free to drop me a note.

Thank you for your understanding and happy editing :) Editing on behalf of User:Jarry1250, LivingBot (talk) 21:06, 14 March 2011 (UTC)

Hi Guswen,

I saw your comments on the Earthquake talkpage. Glad you are OK! Sounded chaotic at the airport. Did you get any pictures at the airport? Or anywhere else showing damage or rescue efforts? --220  of  Borg 01:24, 30 April 2015 (UTC)

Dear Borg, You're right - it was chaotic. I put some airport pictures at , . I also have some pictures and films taken mostly from the cab that we took from Thamel district of Kathmand to the airport an hour after the first shock but they're nothing compared to those now shown on TV.

Great to meet you
Hi! You seem to be as much in love with Mathematics as I am. (See that essay of mine on my own wiki.)

I think the RM at Talk:Łukaszyk–Karmowski metric is probably a lost cause. But you have raised some good points and I hope I have not been dismissive of them. I really value your contributions.

With your interests in Poland and Math I can understand how this article is of particular interest. At least we spell Łukaszyk correctly there (I think)! And I admit I cannot pronounce Łukasiewicz with any degree of confidence, much as I have tried to learn it.

You might also find User:Andrewa/what use is Wikipedia amusing, or Ridiculous Numbers which I must recover from the archive someday. Andrewa (talk) 21:18, 31 January 2021 (UTC)
 * Dear Andrew, It's my pleasure to meet you too.
 * God made the integers, all else is the work of man. I like this Kronecker quote of your essay very much. Though, in my opinion he slightly missed the point, unless he meant God made the natural numbers, all else is the work of man.
 * Dimension n = -1 is a dimension of the empty set ∅ or (-1)-simplex (the “empty simplex”) or the nullity or void. Now, if one assumes that the void contains a single point, it is no longer the void and dimensionality increases to n = 0 (the 1st natural number). But this simple assumption that n > -1 induces all the remaining dimensions and other points that both also satisfy n > -1. The 1st (0 is a natural number) and the last (there is no natural number whose successor is 0) Peano axioms for the natural numbers are therefore sufficient to introduce all the other dimensions n > 0.
 * Primordial Big Bang singularity (a point) is therefore not about an expansion of space and time; it implies an expansion of dimensions. n = 4 makes biological evolution possible and renders three dimensional world and unidirectional time that is perceived by organisms in this way.
 * I know that this is a lost cause. I am simply fed up with the accusations of this function is not a metric as it is not positive definite or considerations about how not to define a metric in mathematics are not relevant, etc., etc. I know that it is not a metric, and my intention was to clear this issue.
 * A metric is related to space or spacetime, which brings an undue burden to quantum theory. I don't think that we should take this concepts for granted along with the axioms they bring. We certainly don't need these axioms to discuss about nature. In particular if we know for sure that no classification is possible without some sort of bias.
 * Your Ridiculous Numbers idea is cool. But I'd rather not discuss about the definition ridiculous unit j, as the multiplicative inverse of zero [are we talking about $$\aleph_0$$ or $$2^{\aleph_0}$$ here] :)
 * Guswen (talk) 08:53, 1 February 2021 (UTC)
 * Yes, I should have said a multiplicative inverse of zero. I stand corrected!
 * Ridiculous Numbers is a parody but also a serious teaching tool. It calls attention to the significance of Peano's axioms. (We were taught that one of them was that one was not equal to zero... that must have been an earlier formulation, or perhaps it was someone else's later attempt. Somewhere I have my lecture notes from one of Vic Dudman's awesome lectures, it may be his own formulation.) That's probably why you like it.
 * (My fave Dudman quote, from Intro Logic I think, is probably If one of you were to come out here and tell me to shut up, or specifically if you were to say "Shut up or I'll hit you", and if I were to shut up, which I might well do, and if you were then to hit me, saying (some acting holding jaw here) "You shouldn't have done that..." then I have no reason to complain. Or at least, not from a logician's point of view. One of my heroes definitely! The subtle reference to WVOQ in those last four words is sublime.) Andrewa (talk) 21:24, 1 February 2021 (UTC)
 * Thank you. I didn't know about Willard Van Orman Quine and Vic Dudman before.
 * My fave quote so far is "For in her (wisdom) is a spirit intelligent, holy, unique, manifold, subtle, agile, clear, unstained, certain, never harmful, loving the good, keen, unhampered, beneficent, kindly, firm, secure, tranquil, all-powerful, all-seeing, and pervading all spirits, though they be intelligent, pure and very subtle". [Ws 7, 22,23]
 * In fact not only a spirit of wisdom but also even a single qubit is both unique and manifold despite the fact that it seems contradicting (I mean a qubit is unique for a given observer after being measured but it can be easily made manifold by being unitarily transformed or measured in a different base).

Notice of edit warring noticeboard discussion
Hello. This message is being sent to inform you that there is currently a discussion involving you at Administrators' noticeboard/Edit warring regarding a possible violation of Wikipedia's policy on edit warring. The thread is Administrators' noticeboard/Edit warring. Thank you. JBL (talk) 18:23, 24 May 2021 (UTC)

September 2021
Your recent editing history at Schwarzschild radius shows that you are currently engaged in an edit war; that means that you are repeatedly changing content back to how you think it should be, when you have seen that other editors disagree. To resolve the content dispute, please do not revert or change the edits of others when you are reverted. Instead of reverting, please use the talk page to work toward making a version that represents consensus among editors. The best practice at this stage is to discuss, not edit-war. See the bold, revert, discuss cycle for how this is done. If discussions reach an impasse, you can then post a request for help at a relevant noticeboard or seek dispute resolution. In some cases, you may wish to request temporary page protection.

Being involved in an edit war can result in you being blocked from editing&mdash;especially if you violate the three-revert rule, which states that an editor must not perform more than three reverts on a single page within a 24-hour period. Undoing another editor's work—whether in whole or in part, whether involving the same or different material each time—counts as a revert. Also keep in mind that while violating the three-revert rule often leads to a block, you can still be blocked for edit warring&mdash;even if you do not violate the three-revert rule&mdash;should your behavior indicate that you intend to continue reverting repeatedly.

Edits to Volume of an n-ball
In your edits to Volume of an n-ball on September 26 and 27, 2021, the roles of User:Guswen and User:Parejkoj were switched. Outside of that date range User:Guswen was pushing for the added text and User:Parejkoj was reverting it, but for those dates the roles were reversed. Can you explain that? — Q uantling (talk &#124; contribs) 12:34, 3 October 2021 (UTC)
 * I changed my mind. Guswen (talk) 13:31, 3 October 2021 (UTC)

Stop it now
Please stop your disruptive editing and move-warring, or you are likely to get blocked from editing Wikipedia altogether. Your cranky fringe original research ideas about negative-dimensional balls have been rejected by a consensus of multiple editors at Volume of an n-ball and move-warring to make a point does not help your cause. —David Eppstein (talk) 22:55, 18 October 2021 (UTC)
 * You're right. Thank you. It doesn't help my cause. Guswen (talk) 14:38, 19 October 2021 (UTC)

October 2021
You currently appear to be engaged in an edit war&#32; according to the reverts you have made on Volume of an n-ball. This means that you are repeatedly changing content back to how you think it should be although other editors disagree. Users are expected to collaborate with others, to avoid editing disruptively, and to try to reach a consensus, rather than repeatedly undoing other users' edits once it is known that there is a disagreement.

Points to note: If you find yourself in an editing dispute, use the article's talk page to discuss controversial changes and work towards a version that represents consensus among editors. You can post a request for help at an appropriate noticeboard or seek dispute resolution. In some cases, it may be appropriate to request temporary page protection. If you engage in an edit war, you may be blocked from editing. JBL (talk) 21:24, 27 October 2021 (UTC)
 * 1) Edit warring is disruptive regardless of how many reverts you have made;
 * 2) Do not edit war even if you believe you are right.

Hello, I'm Tarl N.. I noticed that you added or changed content in an article, Surface gravity, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at referencing for beginners. If you think I made a mistake, you can leave me a message on my talk page. Please cite a source for your modification, it can't simply be added by itself. Tarl N. ( discuss ) 22:22, 6 December 2021 (UTC)
 * I believe that I don't need a reliable source for this simple algebraic expression?
 * $$\kappa = \frac {c^4} {4GM} = \frac {c^2} {D_{BH}}$$
 * simply equals the 1st term in SI units. Guswen (talk) 00:07, 7 December 2021 (UTC)
 * Yes, we do. Per WP:CALC, Mathematical literacy may be necessary to follow a "routine" calculation, particularly for articles on mathematics or in the hard sciences. In some cases, editors may show their work in a footnote. The derivation is non-obvious, at a minimum it needs a footnote showing that equivalence and where all the terms came from. I'd prefer an actual reference. I'll be reverting it, per WP:BRD. you're supposed to discuss and achieve consensus before re-instating your change. Tarl N. ( discuss ) 06:56, 7 December 2021 (UTC)
 * Sub-comment; if there is no obvious reference available to cite, the question arises, why is this specific derivation important? If nobody else has bothered to publish it, do we need it here? Tarl N. ( discuss ) 07:03, 7 December 2021 (UTC)
 * OK. I hear and obey. Guswen (talk) 07:51, 7 December 2021 (UTC)
 * One particular importance is as follows. If we assume that any inertial acceleration a of any mass M (for M and R not bounded by the escape velocity inequality for c) must be lower than a black hole surface gravity, then
 * $$a = - \frac {G M} {R^2} \leq \frac {c^2} {2 R_{BH}}$$
 * which for $$R_{BH} = R$$ shows that inertial potential $$\phi_a$$ is greater than a black hole potential of $$-c^2/2$$
 * $$\phi_a = \frac {G M} {R} \geq - \frac {c^2} {2}$$. Guswen (talk) 16:35, 7 December 2021 (UTC)

You misunderstand. It's not so much necessary to explain it to me, but to leave it obvious in the Wikipedia page. The usual answer is that you cite a reliable source which anyone can check. The principle is that writing a Wikipedia article takes an expert, but it must be maintained by people who may have no more than librarian levels of specific knowledge in the area. If someone comes by two years from now and says "hey, he has the wrong exponent", and changes it to $$c^3$$, it may be obvious to you and I that such a change is incorrect, but as that escalates into an edit war, the person resolving the conflict is likely to be an admin, not an expert in the field. There are admins expert in physics, but a content disupute will generally be resolved by an uninvolved admin, which often means that those with the most expertise are excluded. That admin needs to be able to immediately see what the problem is - hence WP:CALC, only make trivial routine calculations (like age at death given birth date), not more complicated. If it takes a non-physics expert more than a minute or two to figure out (about the amount of time maintainers can afford to any given article), they'll likely get the resolution wrong. And see WP:CIRC why having bad information in an article is far worse than having no information.

That said, the question remains; if you don't have a reference which specifies this, why is it so important to put in Wikipedia? It seems an interesting piece of trivia, why do we need it? What point in this article requires it? Tarl N. ( discuss ) 21:53, 7 December 2021 (UTC)
 * Thank you.
 * The exponent cannot be $$c^3$$ as in this case units would disagree. Potential is measured in $$\text{m}^2/\text{s}^2$$, acceleration in $$\text{m}/\text{s}^2$$. Squared velocity of light is measured in $$\text{m}^2/\text{s}^2$$.
 * This is a routine calculation. Schwarzschild radius is $$ R_{BH} = \frac{2 G M_{BH}}{c^2}$$. Hence $$ M_{BH} = \frac{R_{BH} c^2}{2 G}$$. Thus a black hole surface gravity is $$g_{BH} = \frac{G M_{BH}}{R_{BH}^2} = \frac{G}{R_{BH}^2} \frac{R_{BH} c^2}{2 G} = \frac{c^2}{2 R_{BH}} = \frac{c^2}{D_{BH}}$$.
 * Even if the ultimate relevance of this simple and elementary fact remains to be researched, in my opinion, we should not hinder this research by hiding it. Guswen (talk) 22:26, 7 December 2021 (UTC)
 * Please read WP:NOR. This isn't the place to publish new research. Tarl N. ( discuss ) 22:50, 7 December 2021 (UTC)
 * Surely it isn't. But is that a new research? It's just a primary school arithmetic. Guswen (talk) 23:07, 7 December 2021 (UTC)
 * See WP:SYNTH. If you can't find something that actually says what you want to add, it's either WP:OR or WP:SYNTH. Again, I ask, given that you seem to presume this is not published anywhere else, why is this required for the article? Tarl N. ( discuss ) 00:32, 8 December 2021 (UTC)
 * Because, in my opinion, this primary school arithmetic may inspire someone for further original research and we should not hinder this research by hiding this obvious and non-original information. Guswen (talk) 07:11, 8 December 2021 (UTC)
 * Being obtuse doesn't help. Wikipedia is not the place for (quote) facts, allegations, and ideas—for which no reliable, published sources exist. See WP:NOR. If you dislike my response, you can pursue conflict resolution; possibly third opinion, request for comment, or dispute resolution noticeboard. Tarl N. ( discuss ) 07:56, 8 December 2021 (UTC)

 * If you think that I'm not a "suitable candidate" then keep my IP blocked. I've been on Wikipedia since 2006. And I never did anything wrong. I'm OK to be persecuted. Guswen (talk) 22:45, 7 December 2022 (UTC)

Well, Guswen, here's the thing. No one is "persecuting" you, or Donald Trump, for that matter. You were, apparently, guilty of socking and got blocked because of it, and socking is wrong, so to speak. In my block notice I said, "If you are one of the bona fide users on this IP address range, and affected by this, please request unblocking, and ask for checkuser and IP address block exemption", so the ball is in your court. Are you a bona fide editor? I'm looking at Deletion review/Log/2022 July 13 and all that, and what a waste of people's time that was. I sure hope we won't have to go through something like that again, and so it's probably a good idea to not deny previous disruption: we really don't like socking. It spoils everything. If you can assure us that we are dealing with an honest and well-intentioned editor, than I'm sure can find it in their heart to file the paperwork. Drmies (talk) 01:19, 8 December 2022 (UTC)


 * And what have you learned looking at Deletion review/Log/2022 July 13?
 * To me it was a clear persecution. An article concerning my PhD thesis, existing on Wikipedia since 2008 was deleted (after an appeal) because few anonymous Wikipedians (perhaps fewer than listed but using multiple accounts) requested that.
 * The distance function that I discovered twenty two years ago has merit and |practical applications so I disagreed with this motion and alone engaged in the discussion. In the process I asked a friend to support me and I was accused of socking. But you're damn right. I was spitting into the wind and it was a terrible waste of time.
 * Thus, I won't ask Yamla to look into "their" heart to file the paperwork. Let "they" look by "themselves". Szymon Łukaszyk Guswen (talk) 06:50, 8 December 2022 (UTC)
 * OK--thanks. Given your response, I'm going with "no". Drmies (talk) 15:46, 8 December 2022 (UTC)
 * So you're the Wikipedia ruler?
 * You told me that Yamla is. Guswen (talk) 20:28, 8 December 2022 (UTC)

I mean really
Did you even read the section you're editing? It specifies quite explicitly what kind of object n can be. --JBL (talk) 21:55, 25 February 2023 (UTC)

The section reads that: " The powers of i repeat in a cycle expressible with the following pattern, where n is any integer:

...

This leads to the conclusion that

...

where mod represents the modulo operation. Equivalently:
 * $$i^n = \cos(n\pi/2) + i \sin(n\pi/2)$$

"

Thus I must presume that n is any integer.

If I read something wrong, testify as to what is wrong. Guswen (talk) 21:10, 26 February 2023 (UTC)
 * Adding to JBL's comments, reviving an old conflict between us - read WP:V. DO NOT add stuff from your personal conclusions, analysis, or imagination. Those constitute WP:OR or WP:SYNTH. Additions must be attributable to a reliable source, and immediately confirmable from that source. If your source doesn't say what you are claiming, you cannot add it. If you don't have a source, you cannot add it. This seems to be a variant on your surface gravity addition pattern, something you decided would be a cute factoid, not something you found in a tertiary source which deserves addition.
 * You were temporarily banned during an earlier conflict, and then your return got tangled in a IP range block - now that you appear to be back, be careful to not trigger a permanent ban. Additions like this look very much like WP:NOTHERE. <b style="color:green">Tarl N.</b> ( discuss ) 21:32, 26 February 2023 (UTC)
 * Gentlemen. Please leave me alone. This section reads where n is any integer. And the equation $$i^n = \cos(n\pi/2) + i \sin(n\pi/2)$$ is unsourced. I checked this unsourced equation to find it is valid for complex n, so I added this information. You disagree, and I'm perfectly OK with that.
 * If you insist on claiming it is valid only for integer n, let it be. I did not start this bizarre I mean really discussion. And - I mean really - do not have time to spit into the wind. If I mistakenly upset some Wikipedia ruler(s) again, I humbly ask for forgiveness and a modest punishment.
 * So can we stop this chat now, or will we go on and on, and on... like in here, for example? Guswen (talk) 21:49, 26 February 2023 (UTC)
 * To address the math aspect ... that equation giving the value of $in$ needs a caveat or two if it is to be applied to other than integers $n$. Specifically, when $n$ isn't an integer the expression $in$ is frequently considered to be multivalued.  That is $in$ is often considered to be equivalent to $exp(n log(i)) = exp(n (2\pim + π/2)i)$ for any integer $m$.  If $n$ is an integer then this right-hand side does not depend upon the choice of integer $m$, but when $n$ is not an integer then there are at least two and as many as infinitely many possible solutions.  For example, $n = 1/2$, gives the value indicated by the formula, and its negative.  Yes, one could talk about principal values and make that work, but that hasn't been done and I'm not sure that it's worth it.  To the extent that some of this is already obvious, I apologize in advance.    — Q uantling (talk &#124; contribs) 22:11, 26 February 2023 (UTC)
 * True, the principal value of $$i^n$$ is $$i^n = e^{i n \pi /2}$$, which - using Euler's formula - is $$i^n = \cos(n \pi /2) + i \sin(n \pi /2)$$. And this is valid $$\forall n \in \mathbb{C}$$. So perhaps, someone (not me, of course) would kindly consider having it done? Or will we keep insisting that it is worth claiming that $$i^n  = \cos(n \pi /2) + i \sin(n \pi /2)$$ is true if and only if $$n \in \mathbb{Z}$$, instead? Guswen (talk) 23:48, 26 February 2023 (UTC)
 * And please do not apologize for something obvious. It's not your fault that it's obvious. Guswen (talk) 11:59, 27 February 2023 (UTC)
 * To address “leave me alone”, read WP:COLLAB. If you insist on declaring yourself a lone ranger who operates in defiance of policy and refuses to respond to corrections, that is pretty close to definitive WP:NOTHERE. Your past history recently cost you the assistance of an administrator when trying to work around an IP range block. Continuing your pattern does not bode well. <b style="color:green">Tarl N.</b> ( discuss ) 23:19, 26 February 2023 (UTC)

 * Am I on trial in some criminal case here? Guswen (talk) 10:12, 27 February 2023 (UTC)
 * In your second edit, you added the ridiculous text "(which is valid for some unspecified $n$)". But the domain of validity was correctly specified at the beginning of the section!  (Per your request, I will not post here further unless required to do so by policy.)  --JBL (talk) 23:36, 26 February 2023 (UTC)
 * On the contrary. The domain of validity of the principal value of $$i^n = \cos(n \pi /2) + i \sin(n \pi /2)$$ is not correctly specified at the beginning of this section, as math explains to User:Quantling, in my reply above. Guswen (talk) 07:20, 27 February 2023 (UTC)
 * (Nevertheless, thank you. Please do not post here further until you grasp some math rudiments. Guswen (talk) 07:39, 28 February 2023 (UTC))

Can I presume that we have reached a consensus about the domain of validity of the principal value of $$i^n = \cos(n \pi /2) + i \sin(n \pi /2)$$, gentlemen? Guswen (talk) 16:32, 28 February 2023 (UTC)
 * If there is a consensus, would you do me the favor of stating it here before proceeding? My fear is that we haven't yet achieved consensus.  My worries include that one chooses principal values by designating a branch cut and a sheet (or by similar means) and that a blanket statement that gives $in$ for non-integer $n$ without discussing that is misleading.  I added a sentence after that formula in the article to address this.  Perhaps we could discuss here specific improvements to the article rather than making them on the article page.  (I really do mean "perhaps".  If you see a consensus or if you think my edits don't achieve a consensus then, of course, you also have the option of going boldly on the article page.  However, I urge cautious edits because I worry that we don't actually have consensus yet.)  Thanks — Q uantling (talk &#124; contribs) 17:52, 28 February 2023 (UTC)


 * Thank you for this edit. However, would you mind amending the "...this last equation would apply to non-integer values of n as well" into "...this last equation would apply to complex values of n as well"? Otherwise, what can a reader infer from "non-integer values"? $$n \in \mathbb{R} \setminus \mathbb{Z}$$, $$n \in \mathbb{Q} \setminus \mathbb{Z}$$? it is clear that $$n \in \mathbb{C}$$ in the referred case.
 * I have other, more important, things in my life to go boldly than that. Guswen (talk) 18:20, 28 February 2023 (UTC)
 * Thank you. I rest the case, your honor. Guswen (talk) 20:22, 28 February 2023 (UTC)
 * What publication are you citing in making this change? <b style="color:green">Tarl N.</b> ( discuss ) 21:44, 28 February 2023 (UTC)
 * In making what change? Guswen (talk) 21:58, 28 February 2023 (UTC)
 * If you are talking about a citation for "Although we do not give the details here, if one chooses branch cuts and principal values to support it then this last equation would apply to all complex values of $n$.", I don't have one. If you think that it needs a citation, rather than being a candidate for WP:CALC or similar, then our job here is not yet done.  Personally, I went with "... if one chooses ... then this would ..." because there are also other ways to define $i$ when $n ∉ Z$, but if one bothers to set things up accordingly then one could use this formula.  Your thoughts?  — Q uantling (talk &#124; contribs) 22:05, 28 February 2023 (UTC)
 * Looks like we'll soon need a publication for $2+2=4$ :) It makes me think about Idiocracy. A silly movie, but with a certain prophecy. Guswen (talk) 22:09, 28 February 2023 (UTC) Guswen (talk) 22:15, 28 February 2023 (UTC)
 * I have no interest in debating anything technical with this editor, since that so often results in ad hominem attacks. They seem more interested in arguing and demeaning other editors than in building an encyclopedia. Most recent example from above "do not post here further until you grasp some math rudiments" - unacceptable WP:CIVIL (bullets 8 & 9) violation. Whether that eventually leads to a WP:NOTHERE ban is not directly up to me. My commentary here is that WP:V remains the primary principle of Wikipedia - Any edits made (even "the sky is blue") must be accompanied by a WP:RS citation which actually says what the editor claims. <b style="color:green">Tarl N.</b> ( discuss ) 19:08, 1 March 2023 (UTC)
 * That's simply unbelievable. I noted that some formula is valid for $$n \in \mathbb{C}$$ and not for $$n \in \mathbb{N}$$. In fact, as User:Quantling correctly noted, this is true only for the principal value of $$i^n$$. Then I was personally attacked, ridiculed, and harassed, even though I said I was OK with leaving this formula wrong and I didn't have time to spit into the wind in such futile discussions. And When someone shouted, "But the domain of validity was correctly specified at the beginning of the section!" I advised him/her to check the math him/herself.
 * I've been a Wikipedian since 2006. May I kindly ask you, User:Tarl_N., when did you start contributing?
 * As I already mentioned on some other occasion, I'm OK with being persecuted. So, please go on; relieve yourself. Guswen (talk) 19:54, 1 March 2023 (UTC)

Your edits in Quantum nonlocality
Your additions have been reverted 6 times by 3 different users. I think it's time to accept that they are not improving the article. Otherwise you're engaging in disruptive behaviour and are bound to get your account blocked. Tercer (talk) 08:26, 16 May 2023 (UTC)


 * These are not "my additions". I only reference recent research results concerning quantum nonlocality published in renowned peer-reviewed journals. This is in line with Verifiability and aims in improving the quality of this article.
 * If, as User:Jähmefyysikko claims, some of those sources are misplaced, feel free to introduce them elsewhere in the article. Guswen (talk) 08:47, 16 May 2023 (UTC)
