Indian?[edit]

Why does the article state that Poincare′ was "Indian"? — Preceding unsigned comment added by 70.166.105.91 (talk) 18:57, 20 August 2018 (UTC)[reply]

Not anymore. Vandalism already reverted: [1]. - DVdm (talk) 20:05, 20 August 2018 (UTC)[reply]

"no references"???[edit]

"Einstein's paper was remarkable in that it contained no references at all."

Given the context, that could mean...

a. Einstein did not acknowledge the published work of any other person.

b. Einstein's method did not require a reference clock.

Is it one, the other, or both?

Serious error[edit]

"For details, see…" Why not describe the serious error in the article? I'm told this caused the invention of chaos theory. John Moser (talk) 03:24, 3 August 2020 (UTC)[reply]

pronunciation[edit]

The English pron. (from what I hear on TV etc.) appears to be /pwɛŋkɑːreɪ/ (stress differing in UK and US), but I can't find a source. The OED, Lexico, Random House / dict.com, AHD and Merriam Webster all screw it up one way or another (e.g. recording contradicts transcription, or don't give an English pron. at all). — kwami (talk) 03:57, 12 November 2020 (UTC)[reply]

Misquote in attitude towards transfinite numbers[edit]

The source of Poincare claiming that Set Theory is a disease is Dauben 1979, which isn't given a title. I've read Dauben's 2005 paper "The Battle for Cantorian Set Theory" in which the claim is repeated, and in that paper the source for this is the last section of Poincare's "L’avenir des Mathématiques", but the quote isn't there. Can anyone else find a place where Poincare called Set theory a disease?Nullseth (talk) 00:10, 7 November 2021 (UTC)[reply]

Dauben, 1979 would be Georg Cantor His Mathematics and Philosophy of the Infinite. Unfortunately, Google books doesn't provide page 266. But if someone can track down a copy... --John (User:Jwy/talk) 02:42, 7 November 2021 (UTC)[reply]

Googling further - looks like you ask a common question and it should not be so clearly attributed to him here: https://math.stackexchange.com/questions/1962851/poincar%C3%A9-and-set-theory --John (User:Jwy/talk) 02:49, 7 November 2021 (UTC)[reply]

I've read the paper by Grey Did poincaré say “set theory is a disease”? and it makes a compelling case that Poincare never called set theory a disease. I suggest we remove the first sentence of the subsection or better yet just remove the "Attitude towards transfinite numbers" section completely, since it doesn't fit with the other information in the Character section. Nullseth (talk) 22:21, 7 November 2021 (UTC)[reply]

I can't see anything of relevance to Poincare's denial of the existence of transfinite numbers in the section on his character. — Preceding unsigned comment added by 2A00:23C4:7C8E:1600:4943:B997:A682:A091 (talk) 17:20, 16 April 2022 (UTC)[reply]
