Where would you recommend I look to publishing the results of this work?

I appreciate the distinction between referencing peer reviewed content, and being peer reviewed content.

Is there a reason why the wikipedia engine hasn't been cloned to facilitate the publishing of original material? — Preceding unsigned comment added by Sjnicholls44 (talk • contribs) 16:17, 31 March 2014 (UTC)[reply]

I haven't thought about a wiki for original research. There are various journals of number theory and there are journals that accept papers in many areas of mathematics, including number theory. But if you want to put it on a web site without going through a full refereeing process, you could try this one. Michael Hardy (talk) 15:51, 1 April 2014 (UTC)[reply]

An editor has asked for a discussion to address the redirect Google Australia. Since you had some involvement with the Google Australia redirect, you might want to participate in the redirect discussion if you have not already done so. TheChampionMan1234 06:46, 3 April 2014 (UTC)[reply]

Hi Michael, nearly 10 years since you taught me that Wikipedia was case sensitive! Thanks for your typography on Cayley's sextic. There is no need to change "date" to "year" in citations, unless harvnb is being used, and probably not even then. All the best, Rich Farmbrough, 17:13, 10 April 2014 (UTC).[reply]

Michael, do you know if MO or MO Meta have any kind of private message system, or a way for logged in contributors to contact other contributors by email? I don't an account there so I can't access all of its features, so I can't tell if something like that exists without enrolling. Of course in many cases it's possible to locate the person's contact info with web searches, but not always. Thanks. 70.36.142.114 (talk) 10:36, 18 April 2014 (UTC)[reply]

There was no such system last time I checked. That was a couple of years ago. Michael Hardy (talk) 16:27, 18 April 2014 (UTC)[reply]

Dear Michael, I saw your removal on time series in the article of statistical population. You're right that time series will mostly concern sample data. But there may be exceptions too. For example, take the time series of the number of soldiers in the Roman Empire by January 1st of every year, up to its fall in the year 476. That's definitely population data. (Just for info, this time series text is not original text of myself, it's something that I moved away from the article on Statistics (too much detail there) to the Statistical population article. But at least I can defend the possibility of the text.) Marcocapelle (talk) 18:32, 17 May 2014 (UTC)[reply]

Dear Michael, it seems to me that in Granger causality, the subsections after Granger causality#Reconstructing a sample network are merely describing the detailed experimental procedure of one of the papers. Should I delete it? I hesitate, mainly because it is a big chunk of text (unsourced though). (I have found you because of your edits on another article.) gratefully, Taha (talk) 20:50, 19 June 2014 (UTC)[reply]

You should not be moving the AfD page or the nominated page while it's being discussed; it causes various problems, such as the bot thinking it's not been added to the logs and re-added. If you think it's a notable topic under another title then propose that in the discussion. Or wait until after the AfD is closed to move it or propose a move if it's controversial.--JohnBlackburne^words_deeds 20:08, 22 June 2014 (UTC)[reply]

Hi Michael,

A while back (a year or two?) you spearheaded an attempt to write a promotional essay aimed at getting mathematicians interested in editing on Wikipedia. I know that the effort didn't get very far but I do remember that there were some suggestions for what should be in the essay. I was wondering if you could point me to that material as I have been asked to write such an article for an MAA publication and would like to include any of the ideas that were brought up at the time. Thanks. Bill Cherowitzo (talk) 17:33, 23 June 2014 (UTC)[reply]

I'll see if I can find it. For some reason I didn't like the direction it took. I had thought of writing such a thing myself and my version would have been different from what was being suggested. Who asked you to write the article? AMS Notices? The Monthly? Michael Hardy (talk) 21:52, 25 June 2014 (UTC)[reply]

Thanks. Ivars Peterson (current publication director of the MAA) asked me to submit an article. No specific MAA magazine was mentioned, but there are several that would be appropriate. Bill Cherowitzo (talk) 03:15, 26 June 2014 (UTC)[reply]

Of course people are confused by the intuitive "explanation". That is why it should be rewritten, by someone who actually knows what a vector space is in mathematics, and is not still rooted in some crude notion of position vectors as taught by bad high school teachers (since those are the only kind of vector for which one would usually talk of an "origin" RQG (talk) 23:24, 14 July 2014 (UTC).[reply]

I am a mathematician and I know what a vector space is. John Baez is a mathematical physicist who is highly respected by mathematicians as an expository writer on abstruse concepts and quite prolific in his writing on such things. In this blog posting you see him saying

"An affine space is like a vector space that has forgotten its origin."

I don't think that your understanding of the matter is superior to mine or to his. Michael Hardy (talk) 20:41, 15 July 2014 (UTC)[reply]

In mathematics, appeals to authority are merely a sign of lack of understanding, especially when the authority is known for glib remarks lacking in substance. I will agree that Baez is a better mathematician than you. I understand you are a statistician with a minor in maths at a university of no particular note, and that you think is as good as a first in mathematics from Cambridge. At least Boris Tsirelson understands that A cannot be a vector space without defining more structure, so do not make claims which you have already demonstrated false. RQG (talk) 05:51, 16 July 2014 (UTC)[reply]

I did not raise the issue of academic degrees. And you are becoming rude and writing imbecilic nonsense. Michael Hardy (talk) 22:11, 16 July 2014 (UTC)[reply]

@RQG, I have explained at talk:affine space what I suspect is your principal misunderstanding of the mathematics involved. Michael Hardy (talk) 23:11, 16 July 2014 (UTC)[reply]

I apologise for rudeness, but I think your assessment of my level of ability was also rude. I have responded to your comment on my talk space. John did point out that his description should immediately be made precise, which is certainly true and which is a major reason I have been advocating revision. — Preceding unsigned comment added by RQG (talk • contribs) 06:00, 18 July 2014 (UTC)[reply]

Hello. An IP editor (71.82.112.140) has been adding a lot of wrong wikilinks to articles related to mathematics and physics during the past few days. They clearly have no idea what they are doing and they keep doing so despite all the talk-page warnings by other editors. I think this is a highly actionable case. --Omnipaedista (talk) 15:08, 29 July 2014 (UTC)[reply]

Why did you think that Amelia Bedelia (book) might have been a hoax? The linked article clearly mentions an addition to the article Amelia Bedelia, not the book.--Auric talk 19:44, 30 July 2014 (UTC)[reply]

Thank you for pointing out my capitalization error, I will be more careful in the future. However, the link you redirected quantum master equation to is quite inappropriate. That article provides the quantum master equation FOR "an even degree element W of a Batalin–Vilkovisky algebra" ... it's not the article on "quantum master equations". In fact, The Batalin-Vilkovisky is a bizarre area for the application of a quantum master equation: a highly esoteric subject that only briefly overlaps with the use of quantum master equations in theory, while quantum master equations are more typically used in the study of open quantum systems. Until a real article is made for quantum master equation a more appropriate link would be to http://www.quantiki.org/wiki/Master_equation or to https://en.wikipedia.org/wiki/Open_quantum_system .. but really the only place it should truly be redirected is to an article dedicated to the subject itself. — Preceding unsigned comment added by Dr. Universe (talk • contribs) 11:05, 2 August 2014 (UTC)[reply]

Sorry, but you're quite wrong. I redirected Quantum Master Equation (with capital initial letters) to quantum master equation (with lower-case initial letters). I never redirected anything to Batalin–Vilkovisky algebra. Someone else redirected quantum master equation (with lower-case letters) to that page. Michael Hardy (talk) 12:26, 2 August 2014 (UTC)[reply]

Hi Michael. I recently had to do a PCA, and found it hard to gain intuition into the process from the wikipedia page, or from other online sources. I added an Intuition section to the principal component analysis page, and would appreciate if you could look it over. It's not very good, as I don't really understand PCA that well, but I thought starting an Intution section would be helpful to laymen.Potnisanish (talk) 16:01, 16 August 2014 (UTC)[reply]

Michael, you changed the punctuation in the Gallery in this article, (and probably in others too) , see Modigliani. You can't change the punctuation on an image file name. If you do, you broke the image. See how the gallery looks here in the article.

Now that was reverted by some alert user, here - but think about the galleries, promise? Cheeers, and happy editing. Hafspajen (talk) 11:16, 18 October 2014 (UTC)[reply]

Hi there, I'm pleased to inform you that I've begun reviewing the article Cantor's first uncountability proof you nominated for GA-status according to the criteria.

Thanks for the edits on this page. I have actually created a article out of this draft and I am not able to figure out how to delete this page. The pages are Draft:3D_printer_extruder and 3D_Printer_Extruder. Please look into this and suggest what should I do.

Priybrat (talk) 09:52, 2 November 2014 (UTC)[reply]

Hello Michael Hardy. This message is part of a mass mailing to people who appear active in reviewing articles for creation submissions. First of all, thank you for taking part in this important work! I'm sorry this message is a form letter – it really was the only way I could think of to covey the issue economically. Of course, this also means that I have not looked to see whether the matter is applicable to you in particular.

The issue is in rather large numbers of copyright violations ("copyvios") making their way through AfC reviews without being detected (even when easy to check, and even when hallmarks of copyvios in the text that should have invited a check, were glaring). A second issue is the correct method of dealing with them when discovered.

If you don't do so already, I'd like to ask for your to help with this problem by taking on the practice of performing a copyvio check as the first step in any AfC review. The most basic method is to simply copy a unique but small portion of text from the draft body and run it through a search engine in quotation marks. Trying this from two different paragraphs is recommended. (If you have any question about whether the text was copied from the draft, rather than the other way around (a "backwards copyvio"), the Wayback Machine is very useful for sussing that out.)

If you do find a copyright violation, please do not decline the draft on that basis. Copyright violations need to be dealt with immediately as they may harm those whose content is being used and expose Wikipedia to potential legal liability. If the draft is substantially a copyvio, and there's no non-infringing version to revert to, please mark the page for speedy deletion right away using {{db-g12|url=URL of source}}. If there is an assertion of permission, please replace the draft article's content with {{subst:copyvio|url=URL of source}}.

Some of the more obvious indicia of a copyvio are use of the first person ("we/our/us..."), phrases like "this site", or apparent artifacts of content written for somewhere else ("top", "go to top", "next page", "click here", use of smartquotes, etc.); inappropriate tone of voice, such as an overly informal tone or a very slanted marketing voice with weasel words; including intellectual property symbols (™,®); and blocks of text being added all at once in a finished form with no misspellings or other errors.

I hope this message finds you well and thanks again you for your efforts in this area. Best regards--Fuhghettaboutit (talk) 02:20, 18 November 2014 (UTC).[reply]

A tag has been placed on File:Notation.pdf requesting that it be speedily deleted from Wikipedia. This has been done under section F10 of the criteria for speedy deletion, because it is a file that is not an image, sound file or video clip (e.g. a Word document or PDF file) that has no encyclopedic use.

If you think this page should not be deleted for this reason, you may contest the nomination by visiting the page and clicking the button labelled "Click here to contest this speedy deletion". This will give you the opportunity to explain why you believe the page should not be deleted. However, be aware that once a page is tagged for speedy deletion, it may be removed without delay. Please do not remove the speedy deletion tag from the page yourself, but do not hesitate to add information in line with Wikipedia's policies and guidelines.

The article Cantor's first uncountability proof you nominated as a good article has been placed on hold . The article is close to meeting the good article criteria, but there are some minor changes or clarifications needing to be addressed.

In your edit summary at Georg Cantor, you said "I do not think his first proof is more complex or less elegant than the original. I think the original is more elegant." I think the 2nd sentence contradicts the first one. In my opinion, the 1891 proof is easier to understand than the 1874 proof. Did you mean that, too? - Jochen Burghardt (talk) 23:12, 10 December 2014 (UTC)[reply]

I meant I don't think the 1874 proof is more complex or less elegant than the 1891 proof. Nor do I think it's harder to understand; I think if you're finding it hard to understand, then maybe a clearer explanation should be written. Michael Hardy (talk) 18:13, 11 December 2014 (UTC)[reply]

Well, while neither is terribly difficult, the 1891 proof is certainly shorter. In that sense it's easier to understand.

The great merit of the 1874 proof is that it gives better insight into the behavior of the reals specifically. Descriptive set theorists are likely to like it better, because it's a baby example of the things they do. That's my background, and I like the 1874 proof better. But if a combinatorial set theorist liked the 1891 proof better, I'd have to reluctantly understand. --Trovatore (talk) 21:52, 11 December 2014 (UTC)[reply]

ok..... Michael Hardy (talk) 19:45, 12 December 2014 (UTC)[reply]

I agree with your restoration of the list of initial-stress-derived nouns. There is a way to handle this on Wiktionary: to create a category under wikt:Category:English terms by etymology. I'm not doing it myself at the moment — too laborious — but there's an idea. — Eru·tuon 05:09, 18 December 2014 (UTC) Or an article could be added here on Wikipedia and linked from Lists of etymologies. — Eru·tuon 05:12, 18 December 2014 (UTC)[reply]

Do these words actually share a common etymology not shared by other words? Even if they do, that's not the essence of the matter. This is about a relationship between pronunciation and the meaning of the word, not about etymology. Michael Hardy (talk) 05:26, 18 December 2014 (UTC)[reply]

Etymology is not only concerned with what original word something is derived from, but also what sound changes it has gone through in its derivation from that word. In this case, initial-stress-derived nouns are derived from a verb by a process of stress movement (or at least appear that way as we see them today), so they form an etymological category not by the word they come from, but by the process that formed them. (Check out the Wiktionary link above: there are several subcategories concerned with sound changes: apheresis, apocope, syncope.) — Eru·tuon 19:20, 18 December 2014 (UTC)[reply]

You are absolutely correct, Michael. I intended to get rid of that reference, but somehow restored it. I had written essentially the same thing as you in the TALK section of the article as follows: Admittance to the Union[edit]

Reverted edit. California was admitted to the Union 11 years before the Civil War. Activist (talk) 03:27, 16 January 2015 (UTC)

Added unmentioned presence of Russian coastal colony north of San Francisco Bay, eventually purchased by Sutter. Activist (talk) 04:16, 16 January 2015 (UTC)

Whoever originally put that in there may have also been the one who claimed that there was little European interest in Northern California, so I added the part about the Russian colonies, which also prompted me to clean up the insufficient info on Ft. Ross, Tomales Bay, etc. In fact, until trying to clean that up, I had no idea that Sutter bought out the Russian colony and that his influence was substantially wider than commonly portrayed. The problem seems to be that a great deal of info in the Sacramento article was clumsily written (probably by an editor whose first language was not English) or inaccurate, so I made an attempt to clean up the lead paragraphs, but didn't have the time to go through it all. I noted that it needs considerable work. Thank you for straightening out my inadvertent error. Activist (talk) 14:41, 17 January 2015 (UTC)Activist (talk) 14:51, 17 January 2015 (UTC)[reply]

Hi Michael Hardy. I am Piotr Konieczny (User:Piotrus), you may know me as an active content creator (see my userpage), but I am also a professional researcher of Wikipedia. Recently I published a paper (downloadable here) on reasons editors participated in Wikipedia's biggest vote to date (January 2012 WP:SOPA). I am now developing a supplementary paper, which analyzes why many editors did not take part in that vote. Which is where you come in :) You are a highly active Wikipedian (75th to be exact), and you were active back during the January 2012 discussion/voting for the SOPA, yet you did not chose to participate in said vote. I'd appreciate it if you could tell me why was that so? For your convenience, I prepared a short survey at meta, which should not take more than a minute of your time. I would dearly appreciate you taking this minute; not only as a Wikipedia researcher but as a fellow content creator and concerned member of the community (I believe your answers may help us eventually improve our policies and thus, the project's governance). PS. If you chose to reply here (on your userpage), please WP:ECHO me. Thank you! --_{Piotr Konieczny aka Prokonsul Piotrus| reply here} 23:29, 11 February 2015 (UTC)[reply]

You said you are annoyed by my articles. Sorry. I do not write TeX by hand. I convert it from TeXmacs/pandoc. Writing TeX by hand would be a huge mess. Apparently, the conversion does not output TeX up to the standards of wikipedia. I will not be fiddling with TeX by hand simply because that is a waste of time. Therefore, I will stop writing anymore articles. If my 2 or 3 articles are too much trouble for any editors to fix to wikipedia standards, then they can be deleted. Good luck. Twy2008 (talk) 08:59, 19 February 2015 (UTC)[reply]

I could also point out that your replacement of \mathrm{sin} with \sin has effectively vandalized the "Quaternion rotation biradial" article. At least one of the replacements didn't format correctly at Identities:_Product_ba_and_rotation_operator_R. Btw, not every function in mathematics has a specific LaTeX command like \sin, so in general, a function probably has to be written just the way I did it. I'm not sure it is my role anymore to try to fix this vandalism, or argue this any further. Twy2008 (talk) 15:35, 19 February 2015 (UTC)[reply]

I did not say I was annoyed by your articles. I was annoyed by TeX code that was far more complicated than necessary. I have good news on one point: You could probably learn what you need to know of "TeX" for these articles in fifteen minutes. To call in "TeX" is quite exaggerated; it is only a system of coding mathematical notation nearly identical to what TeX uses. There's no need to actually learn TeX in order to use it.

Wikipedia generally tends to be fairly sparing in its use of capitals. Actually I think in this case a capital might not be unreasonable because "witch" in this instance is not a common noun; one does not speak of various sorts of generic "witches", of which is is just one.

Hi, I just created a new article on implicit curves which is essentially a translation of the German WIKI (implizite Kurve) I created some weeks ago. Please could You or some one else check the language. It may not meet the WIKI-standard. Thank You !--Ag2gaeh (talk) 12:12, 1 April 2015 (UTC)[reply]

Michael, I don't see why you deleted one of the examples in the page Proof by contradiction. There wasn't really anything wrong with that example (summary: if there is a largest prime p, take any prime factor of p! + 1, that will be larger, contradiction, so there isn't a largest prime p). MvH (talk) 02:49, 12 April 2015 (UTC)MvH[reply]

Hi Michael - I notice that you have been working on several of the individual sporadic simple group articles. I saw your change to Thompson sporadic group with the comment, "In group theory obviously does not tell non-mathematicians that mathematics is what this is about" and applied your same fix to the other 25 sporadic group articles (plus a few more with the same defect). Thanks. Since you may be interested, I invite you to look at User:Foobarnix/Revision and cleanups to individual sporadic group articles. We can talk more on that page if you like. --Foobarnix (talk) 17:43, 30 April 2015 (UTC)[reply]

Hi Michael,

Recently there has been drive-by vandalism by IPs at a number of pages including Galileo Galilei, The Assayer, and Method of indivisibles. Could you "protect" the latter page so only autoconfirmed users can edit it? Tkuvho (talk) 13:48, 21 June 2015 (UTC) As I was writing the previous message, the same IP blanked The Assayer. I would much appreciate if you could "protect" that one, as well. Tkuvho (talk) 13:51, 21 June 2015 (UTC)[reply]

Hi Michael,

Sorry that I couldn't participate in the GA Review for Cantor's first uncountability proof. I didn't have the time then. Looking over what was said, I agree with SpinningSpark that the article needs a fundamental restructuring. I now have the time to work on a rewrite. I've already written a new lead (see User:RJGray/Cantor draft1) that handles SpinningSpark's point about whether the disagreement about Cantor's proof is a decades long dispute. I plan to work through SpinningSpark's excellent feedback. I really appreciate the time and thought he put into it. I also appreciate JohnBlackburn's feedback.

The new lead is also a "real lead": it leads into what is covered in the Wikipedia article including Cantor's development of his ideas (which SpinningSpark pointed out was not in the old lead). You may notice that I'm switching the order of the sections now titled "The development of Cantor's ideas" and "The disagreement about Cantor's proof." Doing this not only makes the lead flow better but also helps me handle some of feedback.

So I'm prepared to do a rewrite, but I need to know if anyone else is working on one, and whether the new lead is going in the right direction. I should warn you that my rewrite will take a bit of time. I believe that we can create an article that will attain Good Article status, but for me, good writing takes time and feedback. I'll need some feedback after I finish each section. By the way, I'm curious: do many people read the article as compared to other math or math history articles (the article is really a mix of the two), or is it not read much, or is there no way to know this?

Thanks again for nominating the article for Good Article, thanks for the edits you made to make it a better article, and thanks for attempting to bring it up to GA standards. Unfortunately, the writing I did in the article was not close enough to GA standards for you to succeed without a major rewrite. I'm sorry that my writing wasn't closer to GA standards, but I'm not surprised since it was my first contribution to Wikipedia and I didn't know the rules. RJGray (talk) 20:26, 11 July 2015 (UTC)[reply]

Take a look at this page. It reports that as of through the 10th of August, the article has been viewd 439 times during August. It was viewed 1208 times in July. Michael Hardy (talk) 19:43, 11 August 2015 (UTC)[reply]

Hi Michael,

I've just completed a draft of the first three sections of my rewrite (see User:RJGray/Cantor draft1). They were fairly straightforward sections to write; I know the next two will be harder. I've kept all the math in the first two sections (the current article mixes math with the discussion about the nature of the proof). This along with the math I added tries to address the complaint about not that much math in a math article. Now the readers who just want to read math only have to read the first two (or three) sections; the third section is a bridging section. Of course, the article as a whole contains both math and math history, but now it's more cleanly separated. Also, I've taken the two proofs out of the footnotes, used the "math proof" template, and motivated and rewrote the proof about intervals excluding leading terms (in fact, this proof motivated me to simplify Cantor's proof).

I've simplified Cantor's proof by using open intervals, which also simplifies the case diagrams, the proof about excluding leading terms, etc. There will be 3 diagrams, one for each case in the construction. However, the case diagrams are not done yet. I only recently contacted someone who is doing them for the article. The case 1 diagram should handle SpinningSpark's observation about someone getting confused because it deals with a finite interval. Geometrically, it's obvious that in case 1, c is different from x_n. I look forward to your comments.

On another subject: Euclid's proof that there are infinitely many primes. I remember that after you sent me the excellent article that you and Catherine Woodgold wrote, I traced the proof-by-contradiction back to Dirichlet. While reading up on the history of non-constructive proofs, I came across the following that states that Dirichlet was the first to use non-constructive existence proofs and that he used them in his number theory investigations: History and Philosophy of Modern Mathematics, vol. 11, p. 249. Here's footnote 27, which references Klein's book: History and Philosophy of Modern Mathematics, vol. 11, p. 257. Also, you may want to look at the proof in Wikibooks: Euclid's proof of the infinitude of primes. It states "Euclid's proof works by contradiction."

By the way, do you know why Wikipedia removed the MathJax option from the Appearance tab in Preferences? Also, MathML is giving me blanks (when printing) now. It was working for me about a week ago but it doesn't anymore. At least, PNG still works. Thanks, RJGray (talk) 17:07, 10 August 2015 (UTC)[reply]

I hadn't noticed those changes. Maybe one of the regulars at Wikipedia talk:WikiProject Mathematics would know about this. Michael Hardy (talk) 19:33, 11 August 2015 (UTC)[reply]

Hi Michael, I've updated User:RJGray/Cantor draft1. Here's the major changes: Added section "The disagreement about Cantor's proof"; added Jochen Burghardt's case diagrams; separated notes and references. The case diagrams are in the section "The Proofs". Please send me any suggestions or corrections to the article (or you can make your changes directly on the draft). Thanks, RJGray (talk) 20:47, 28 September 2015 (UTC)[reply]

Hi Michael, I have now finished my first version of my first draft: it's in User:RJGray/Cantor draft1. I'm still actively working on it. I'm improving some of the writing. I've recently shortened my original "Dedekind's contribution" section and I'm looking for other places to shorten. I also need to check my links and do some miscellaneous tasks. I suspect it will take me about a month; I'd like to get it done by the end of the year. Any feedback would be appreciated. By the way, I'll be away from computers for about a week. RJGray (talk) 15:36, 21 October 2015 (UTC)[reply]

Interesting. I'll look at the draft. Michael Hardy (talk) 18:38, 22 October 2015 (UTC)[reply]

Hi Michael, I've now finished my second draft: it's in User:RJGray/Cantor draft2. Did quite a bit of editing throughout. The biggest changes are: I redid parts of two proofs in "The Proofs" section (the proof of Cantor's second theorem and the dense sequence proof), and I added a short legacy section. I added this section for at least two reasons: ending with Dedekind's contributions leaves one with a negative feeling about Cantor—the legacy section ends more positively by telling how Cantor's contributions affected mathematics. Also, it points out the dual legacy of the article: the concept of countability and the uncountability theorem. The last paragraph combines the two with Skolem's insight into the uncountability theorem.

This second draft should be very close to the final draft. I made a few small changes today and probably will do some more small changes here and there. Also, I have some miscellaneous tasks to do (like making a final check of all my references). It should take a few more weeks; I'd still like to get it done by the end of the year.

By the way, is the plan to just post the article or let some editor make comments beforehand? Thanks, RJGray (talk) 22:39, 22 November 2015 (UTC)[reply]

Hi Michael, Just want to clarify my last sentence about "some editor": I know that you are an editor, and your comments are always welcome. I was wondering about one of the editors involved in the GA Review. Thanks, RJGray (talk) 15:27, 23 November 2015 (UTC)[reply]

I was going to move the California Legislature Session pages that have an en dash in them to not have one. I could not imagine why anyone would think this is correct? :-) Can you explain why "2015-16" should have an en dash? Separate from mathematics (which I am not sure of) does anyone suggest that titles should have en dashes in them? It makes it hard for tools, such as one I am writing, to deal with the URLs.

Ok. It turns out that I am wrong about this. I checked the MOS.

But. It says that for any page which uses this in its title, there should be a re-direct for the page with a hyphen. See MOS:DASH. Do you have any suggestion for how this can be handled. Since you did the re-naming to change the titles to use an en dash, can you create the re-direct pages? It would be appreciated.

RayKiddy (talk) 22:44, 16 July 2015 (UTC)[reply]

It is standard that ranges of years and ranges of pages use en-dashes (not em-dashes). Thus an article's initial sentence says:

Sir Winston Leonard Spencer-Churchill, KG, OM, CH, TD, DL, FRS, RA (30 November 1874 – 24 January 1965) was a British statesman who was the Prime Minister of the United Kingdom from 1940 to 1945 and again from 1951 to 1955.

The date of birth and date of death are separated by an en-dash. If it had given onlly the years, it would have said Sir Winston Leonard Spencer-Churchill, KG, OM, CH, TD, DL, FRS, RA (1874–1965), with no blank space before and after the en-dash. Similarly, ranges of pages use en-dashes, thus: The Gathering Storm pp. 170–71. If a hyphen rather than an en-dash had appeared there, I would have changed it to an en-dash with an edit summary saying I'm correcting a punctuation error. It's used in things like this: "Butterfly fossils date to the mid Eocene epoch, 40–50 million years ago." Note the en-dash in "40–50". It is also used in physical measurements, e.g. 2.5–3 kg, and with letters of the alphabet, e.g. A–F.

If I'm not mistaken, all this is codified in WP:MOS. Michael Hardy (talk) 16:14, 17 July 2015 (UTC)[reply]

My issue is not with en dashes in general. I was just finding it inconvenient that the en dash appeared in the title. It makes dealing with the URL for the article more complicated. And I do think that, even if it is correct to use an en dash in the title, there needs to be a re-direct page so that people searching for "2015 *hyphen* 16" find a page even if its title contains "2015 *en dash 16". But I can create these re-directs. Sorry if my comments seemed grumpy and thanks for the reply. Cheers. RayKiddy (talk) 17:02, 17 July 2015 (UTC)[reply]

Dear Michael,

Your mathematical contributions over the years are appreciated. However, you persist with replacing valid low-complexity TeX math markup with ad hoc presentation markup such as bold and italic sequences. Could you please reconsider this? In modern browsers math markup is rendered well via a choice of MathML, CSS or images, whereas ad hoc markup seldom matches the surrounding text well – if you want to see more starkly what I mean, then try increasing the font size or specifying another typeface, as many people with impaired vision have to do. Moreover, screen readers need to parse the complex sequence of ad hoc markup, instead of simply using the contents of the math tag as-is. The sole blind student I have taught certainly preferred the raw TeX of "markup-math x^n + y^n = z^n markup-math-end" to having to follow sequences like "bold-x-unbold superscript-n-close-superscript plus bold-y-unbold superscript-n-close-superscript = bold-z-unbold superscript-n-close-superscript". If you have a cogent reason why ad hoc markup is still to be preferred in 2015, then please share it: I remain open to being convinced, but currently I have no choice but to frown upon your wide-ranging replacements of semantically meaningful math markup with ad hoc presentation markup.

Hey for some reason I just felt like I could drop back by in a few years and you'd be still plugging along. You have invested so much work. I wanted to say that I was a direct beneficiary of some high level math theory discussion a few years back we had and that I was greatly impacted by the ability to interact with sharp minds like yourself here on Wikipedia where there's all types of users with all types of knowledge. For that I'm grateful and it was specifically about physics and a weird relationship between one equation and a number-theory relationship which nobody had yet pieced the two together.

When my exploratory question lead you to arrive at the same conclusion I was on the verge of making myself, it completely transformed me as a math hobbyist and into a math addict, haha. Well, just wanted to share your random impact on my life a few years ago which has led me to a lifelong hobbyist involvement in math and physics where I have an incurable obsession of ascribing causality to the parameters of various math equations which govern the laws of our physical universe.

Hi Michael,

I have restored some old contents on the cis() function you contributed to the List of trigonometric identities back in 2003 and 2006. I stumbled upon cis(x) being mentioned in several related articles but I never found a "central" discussion of its usage from the viewpoint of the function itself, therefore I felt we need a separate article on it: cis (mathematics), as was suggested in one of the past discussions. The article is still unsourced and it needs some copy-editing for a better logical flow and to remove some redundancy. Since you were the original contributor I thought I'd let you know. It would be great if you could help out with some references etc. Thanks and greetings. --Matthiaspaul (talk) 02:39, 6 January 2016 (UTC)[reply]
