Mechanical Engineering[edit]

Euler made important formulae for the buckling of colums which are not dicussed here.

Expressions That May Lead to Confusion[edit]

Section 2.1 Mathematical notation, line 3: He also introduced ... the letter e for the base of the natural logarithm (now also known as Euler's number)

Section 2.5 ... describing numerous applications of ... Euler numbers

It is hard to distinguish between Euler's number and Euler number. Although there are seperate pages devoted to the two concepts, this may still lead to confusion for beginners and those who use English as a foreign language. Shouldn't there be "see also" links behind both expressions?

Underemphasis - Physics[edit]

I see NO mention of the Euler-LaGrange equation which is of fundamental importance for Lagrangian Physics (Mechanics). It is fair to say that Newtonian, Hamiltonian, and LaGrangian Physics are three (complementary) bases of (Classical) Physics, such an important foundational tool should certainly be mentioned in any biography about one of the developers, shouldn't it? More generally used mathematics should be given prescedence over trivia (more specialized , of interest only to fan-boys&girls)? I am not familiar enough with the development of the equation to add anything myself. My gosh, where would the application of the calculus of variations be without it? Why is an engineering equation the first sentence of the Physics and Astronomy section??173.189.75.163 (talk) 14:06, 2 July 2014 (UTC)


WeRelate[edit]

A record for this person has been created in the WeRelate genealogical website. --User:Ceyockey (talk to me) 15:02, 9 February 2015 (UTC)

TYPO in footnote, in the {{Infobox scientist}}[edit]

In the article, near the end of the {{Infobox scientist}}, (under "Notes"), there are two sentences, and the second one says "He is listed by an academic genealogy as the equivalent to the doctoral advisor of Joseph Louis Lagrange.[1]".

The problem is, in the footnote. The footnote says:

Leonhard Euler at the Mathematics Genealogy Project

; but it is coded using a macro, that ("via" the use of the ref "name" mathg), amounts to this: {{MathGenealogy|id=17864}} ...which displays as this:

Leonhard Euler at the Mathematics Genealogy Project

...which is NOT the "MathGenealogy" entry for Leonhard Euler (that would be "38586", not "17864"). It is the "MathGenealogy" entry for "Joseph Louis Lagrange".

There are various ways that this could be remedied ... either change the name (it probably "defaults" to the name of this article ... but there might be an "optional" parameter, to the "MathGenealogy" macro or 'template', to over-ride that...) ... OR, to just change the number.

IMHO, the simplest (and best) solution, would be to just change the number -- from "17864" to "38586".

Thus: Leonhard Euler at the Mathematics Genealogy Project

However, never having (yet) edited this article, (or else I've forgotten), I would like to get consensus first before proceeding. Tacit consensus (consisting of "NO REPLIES at all") [or, only replies ridiculing the hesitancy] will be interpreted (by me) as a special case of that (kind of [sufficient]) consensus.

Any advice, or other comments, would be appreciated. --Mike Schwartz (talk) 23:55, 26 February 2015 (UTC)

Removal of religious beliefs from lede[edit]

@Smk65536: Euler's religious beliefs have been removed from the lede, see diff. The lede is supposed to summarize the article, which was a section on 'personal beliefs', therefore a mention in the led is appropriate. Jonpatterns (talk) 17:47, 20 June 2015 (UTC)

It does need to be proportionate compared to his other contributions, which is only briefly mentioned in the lede. This is why I do not think the religious part is relevant enough. Smk65536 (talk) 18:01, 20 June 2015 (UTC)
