Talk:Pafnuty Chebyshev

Family

One of thirty-six children? All the sources that I've come up with only mention his parents having nine children. Eliezerappleton (talk) 07:02, 11 January 2008 (UTC)

Shooting

The article refers to the "theory of shooting". Is this more conventionally known as the "theory of ballistics"? Perhaps there is a subtle difference which I don't know, so I've left it unchanged in my edit today, although I've not heard the term "theory of shooting" in English. — Preceding unsigned comment added by Mike Shepherd (talk • contribs) 13:45, 27 July 2007 (UTC)
You are right. I just translated the Russian expression "teoriya strel'by". Kgsteffens 14:30, 31 August 2007 (UTC)

Transliteration

The german transliteration Tschebyscheff is still in use, it is not obsolete.

Would anybody know the correct pronunciation of Chebyshev? By the cyrillic letters, it would seem as if Chebyshov might be the more correct version to spell it, cf. "Potemkin". pirogo, 2004-Nov-22

IPA: tʃɛ-bɪ-ʃəf

The third syllable is stressed and pronounced as "of". See the Great Soviet Encyclopedia. --Kgsteffens 14:50, 11 January 2007 (UTC)

Well, according to the Great Soviet Encyclopedia, it's really [t̪͡ɕəbɨˈʂof]. Soviet science historian K. Rybnikov in his book "History of Mathematics" (p. 286 of the 2nd vol.) stated that Chebyshev himself pronounced his last name in that way. Also, current transcription is incorrect even with the given pronunciation (which is also wrong): it should be [ˈt̪͡ɕɛbɨʂəf]. It is believed that the incorrect pronunciation is due to problems with the letter Yo. Anqai (talk) 18:21, 30 November 2013 (UTC)

Most of people in Russia think that "Chebyshev" with stressed first syllable is right because in all books usually used "е" (je) instead "ё" (jo), but really "Chebyshov" with stressed third syllable is more correct. m-piligrim, 12 July 2014 — Preceding unsigned comment added by M-piligrim (talk • contribs) 16:50, 12 July 2014 (UTC)

Thankyou for finally straightening this out. I asked a BUlgarian once, and he told me that some families were chebishev and others chebishov, it depended where they came from, so he could not tell me which one was our number theorist. See https://ru.wikipedia.org/wiki/%D0%A7%D0%B5%D0%B1%D1%8B%D1%88%D1%91%D0%B2,_%D0%9F%D0%B0%D1%84%D0%BD%D1%83%D1%82%D0%B8%D0%B9_%D0%9B%D1%8C%D0%B2%D0%BE%D0%B2%D0%B8%D1%8798.109.151.195 (talk) 03:47, 15 February 2016 (UTC)

Conflicting Birthdays

I am not sure but what is Chebyshev's correct birthday? 4th May or 16th May? can anyone correct the error, since this is conflicting information in line 1 and 3 and I am not sure of the correct date. — Preceding unsigned comment added by 152.7.193.101 (talk) 17:48, 24 April 2006 (UTC)

Done. It's Old Style vs. New Style difference. Mhym 18:42, 24 April 2006 (UTC)

Spelling of Name

Just for fun I entered 36 different spellings of his name into Google and tabulated the number of hits. Three forms of the first syllable - Ch, Tch, and Tsch, and twelve forms of the last syllable - shev, sheff, shov, shoff, chev, cheff, chov, choff, schev, scheff, schov and schoff. The middle syllable was eby. Results are in the table below. Then I discovered that the first syllable could also be sh, tsh or kh, the middle syllable could be eby, ebi, ebie, ebe, ebye or eba. Also the last syllable could be shef, shof chef, chof, schef or schof. This gives a total of 648 spellings, and no, I didn't. PAR 03:32, 13 August 2006 (UTC)

You may have missed some, such as bya in the middle [1] or ye or yo near the end [2] [3] or single f at the end [4]. And even these obvious ones leave out popular examples such as Cebysev [5]. Some of these may be errors (and in a few cases someone else with the same name). --Henrygb 22:34, 2 October 2006 (UTC)

1. The -ёв ending is the same as in Gorbachev.
2. Romanization of Russian gives Čebyšëv ("Scholarly", ISO '68, GOST '83, '02), Cheby'shyov (GOST '71), Chebyshëv (ALA-LC, BGN), Chebȳshëv (British Std) and Chebuishëv (British Library's version of BS).

[FWIW the Google hits are 6 600, 1, 1 520 000, 4, 5. Also, my lecturer would switch between various spellings, even using different romanizations for Chebyshev, Lyapunov ("Liapunoff" etc :p) and so on.] 118.90.48.231 (talk) 13:36, 16 April 2010 (UTC)

Failed to parse LaTeX

Is it just me, or is there a problem when displaying the LaTeX-formulas. I always get an error: "Failed to parse (Cannot write to or create math output directory)". Strangely enough: all previous versions work (even thought the previous edits were not about the formulas) as well as clicking on "edit this page" and then showing the preview. Is this a minor glitch or a more serious problem? The LaTeX works on other pages fine. --92.226.34.226 (talk) 14:08, 12 July 2009 (UTC)

Transliterations

Twice now it has been inserted in the article that "Tchebychev" is the most common transliteration. There is little doubt that the most common in modern works is "Chebyshev". This is born out by the ngram. All my textbooks, which are quite old, spell it "Tchebycheff" and everyone in the '60s spelt it that way. The ngram without Chebyshev also bears out my belief. "Tchebychev" hardly makes a mark in either ngram; something a little more convincing is needed before the article can say this. SpinningSpark 17:06, 10 May 2012 (UTC)

Suppression of edit

I reverted one large edit by ip 68.4.175.187 for the following reasons: the lead is not the place for transcriptions of his name in a variety of languages in which he didn't publish; this edit contained several unsourced assertions, in particular concerning his disease; "Chebychev's rule" appears to be nothing else than the Chebychev inequality mentioned just above.Sapphorain (talk) 09:25, 22 October 2016 (UTC)
