Has anyone made a Venn Diagram of the differences and similarities between Euler Diagrams and Venn Diagrams before? Tiny Desk Engineer (talk) "My user page can't be vandalized if it never existed" 21:30, 6 January 2023 (UTC)

Yes. See John (talk) 12:19, 7 January 2023 (UTC)
I'm confused about how 3 would only be a subset of the overlap, I would think you know what each is iif you know the difference. Unless I'm reading it wrong because I don't actually understand the difference (and therefore would not know what at least one of them are) 22:39, 6 March 2024 (UTC)

I made a transcript. PoolloverNathan[talk]UTSc 21:34, 6 January 2023 (UTC)

Could be interpreted as a case of "I 'know' it when I see it". Two very definite types, including those who are very definite about both, but only some of those who could also be considered accurate enough to differentiate between the two. 23:50, 6 March 2024 (UTC)

Other things named after Euler include: Euler method, Euler angles, Euler equations (fluid dynamics), and lots of other stuff in this article: Contributions of Leonhard Euler to mathematics. Orion205 (talk) 03:22, 7 January 2023 (UTC)

I can't hear Euler without thinking of one episode of Big Bang Theory when they were goofing around with a Euler Disk. :) NiceGuy1 (talk) 06:04, 7 January 2023 (UTC)

If we are gonna nitpick numbers are Euler's Words; Single digit would be Euler's Letter 17:42, 7 January 2023 (UTC)

came for this. Of course, in English a and I would be in the intersection of Euler numbers and Euler digits. 11:51, 8 January 2023 (UTC)

This is probably a response to comments he presumably received about past comics (e.g. which were Euler diagrams labelled Venn 20:31, 7 January 2023 (UTC)

I agree and have added something about that --Kynde (talk) 09:27, 9 January 2023 (UTC)

Don’t forget Eulerian graphs! Klevasseur (talk) 22:09, 7 January 2023 (UTC)

John Venn's cricket bowling machine would bowl cricket balls, like a baseball pitching machine. It was not a tiny pinsetter. 23:34, 7 January 2023 (UTC) took a while for me to get the reason for that statement, Grasshopper. Spent far too long thinking about how (and, indeed, why) you'd use an automated stump-resetting machine (or two, one at each end) when there are several people pretty much on the spot(s) already. ;) 02:54, 8 January 2023 (UTC)

TIL that Carroll diagrams (1886) actually postdate Venn diagrams (1881); they're different ways of doing the same thing, and I was under the impression that Carroll did it first. I like Carroll's version better for being able to un-awkwardly portray all eight options, though, instead of merely seven. -- 23:18, 8 January 2023 (UTC)

Euler Letters ... To a Princess? -- We B Martians (talk) (please sign your comments with ~~~~)

After this comic, it seems there can be a debate about weather previous mistakes from Randall was mistakes or on purpose, but for sure it is a reaction to the two comics he calls Venn diagrams when they are in fact not. I have updated the explanation for both Venn and Euler diagrams categories and mentions those two comics along with this comic. Also I have now included those two other Venn comics in the Venn category, just like this one is already, as Venn diagrams are mentioned even though they are not drawn, since it is Euler diagrams that are drawn. Please do not remove them again. They are Venn diagrams related even though only Euler diagrams are used. I have also mentioned this in the new diagrams explanations. --Kynde (talk) 09:27, 9 January 2023 (UTC)

The title text is wrong, since the set of 'most of maths', and specifically the most of maths created by Euler, would itself contain some of the 'overlapping circle diagrams'. 09:44, 9 January 2023 (UTC)

The list of things named after Euler is absurdly long, but there could also be a an even longer list of things that should be named after him but are named after someone else ... 11:13, 9 January 2023 (UTC)

"Euler's constant" may refer to pi, tau, e, or the gamma constant. 06:17, 12 May 2023 (UTC)

Technically just the latter, but perhaps some confusion with e or other values. Surely not with pi/etc, though, except as part of his Identity. 09:15, 12 May 2023 (UTC)
