Sieve of Nicholls[edit]

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 (talkcontribs) 16:17, 31 March 2014 (UTC)

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)

Cayley's sextic[edit]

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 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).

Math Overflow[edit]

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)

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)

Disambiguation link notification for April 28[edit]

Hi. Thank you for your recent edits. Wikipedia appreciates your help. We noticed though that when you edited Sheppard's correction, you added a link pointing to the disambiguation page Estimation (statistics) (check to confirm | fix with Dab solver). Such links are almost always unintended, since a disambiguation page is merely a list of "Did you mean..." article titles. Read the FAQ • Join us at the DPL WikiProject.

Statistical population / time series[edit]

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)

A historical perspective on moment in physics and mathematics[edit]

I have posted a comment in your article/discussion on 'moment'. Please consider my request to elaborate the historical perspective on the issue. Bkpsusmitaa (talk) 16:24, 23 May 2014 (UTC)

Request for comment[edit]

Hello there, a proposal regarding pre-adminship review has been raised at Village pump by Anna Frodesiak. Your comments here is very much appreciated. Many thanks. Jim Carter through MediaWiki message delivery (talk) 06:46, 28 May 2014 (UTC)

Cleanup of a page[edit]

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 chuck of text (unsourced though). (I have found you because of your edits on anohter article.) gratefully, Taha (talk) 20:50, 19 June 2014 (UTC)

AfD page moves[edit]

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.--JohnBlackburnewordsdeeds 20:08, 22 June 2014 (UTC)

an essay[edit]

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)

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)

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)

Thanks[edit]

Michael, thank you for your edit of "ell" in Zhao Youqin's π algorithm which makes a formular much more readable than "l", which looks like "one" --Gisling (talk) 23:43, 26 June 2014 (UTC).

affine space[edit]

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).

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)

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)

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)

@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)

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 (talkcontribs) 06:00, 18 July 2014 (UTC)

Reviewing Interior reconstruction[edit]

I am helping to encourage editors to improve articles to which they have edited or created recently. In regard to the article: Interior reconstruction, the following assessment has been placed on the page:

Feel free to remove this post from this talk page if you would like. Since you have shown an interest in this article's improvement I thought you might like to have this information.

IP editor[edit]

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)

Hoax??[edit]

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)

Quantum master equation[edit]

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 (talkcontribs) 11:05, 2 August 2014 (UTC)

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)

PCA page edits[edit]

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)
