Talk:Greek letters used in mathematics, science, and engineering

message: A few edits ago the lower and upper case Greek letters were  the combined under one heading. In many cases the indication of which one is meant was lost. This needs some cleaning.
Additionally, the explanations in the bullets start at random with a small or capital letter. Usage in wikipedia seems to be small letters in lists. −Woodstone 11:43, 2005 Jun 4 (UTC)
:The small/capital letters in the lists are not random. Concepts listed under a small letter are designated specifically by the small letter, and those listed under a capital, by the capital - in fact, if you look at some of the letters, for instance delta, there are two sub-lists of things small delta stands for, and things capital delta stands for.

replies: text: You are reacting to a 7-year old comment. Just before it, someone had merged small and capital letter sections. The "random" remark was addressed at the bulleted explanations, not the symbols. −Woodstone (talk) 05:40, 14 March 2012 (UTC)

message: A lot of Greek letters are also used in science and engineering. What do you think, should we add them here (perhaps after appropriate rename) or start a new article? −Woodstone 20:33, 2005 Jun 17 (UTC)
*I'd say add them here. A comprehensive single list beats multiple lists – this can always be renamed to, say, Greek letters used in mathematics, science, and engineering. AиDя01DTALKEMAIL 20:45, Jun 17, 2005 (UTC)
I've moved the page to Greek letters used in mathematics, science, and engineering and merged it with Greek letters used in physics. There were some concepts that I couldn't find a proper link for. Also I believe it would be better if the concepts under each letter were arranged from general to esoteric, because I think this list is of most use to students.

message: I know this list is never going to be exhaustive – and as a chemist myself I am biased – but chemistry, both physical and general, does seem woefully underrepresented here! 89.168.81.58 (talk) 22:49, 8 August 2016 (UTC)

message: Is there html code for a character that looks like \phi but not \varphi?
Also the table listing tex code does not mention \varphi.  Instead it seems to put \phi and φ together. Thenub314 (talk) 11:00, 12 September 2008 (UTC)

message: I've never seen an unadorned \epsilon used to refer to that ordinal, only \epsilon_0.  Does it still belong?  If we're including decorated uses, then the use of \Sigma, \Pi and \Delta in the arithmetical hierarchy also belongs.  —Preceding unsigned comment added by 202.89.137.149 (talk) 10:14, 21 August 2009 (UTC)

message: One of the listed uses of Chi is as 'a variable in algebraic equations'. I don't know of, and can't find any other reference to any such use. The only thing I can think of is that this is referring to the common use of 'x' as an unknown in equations, but not only is this not really a convention or understood meaning - x is only a commonly used letter, and any symbol can be (and often are) used with equal validity - more importantly, it's the Latin letter x, not Chi.
Does anyone know if this is what was meant (or know of such a use of Chi)?CarrieVS (talk) 19:28, 13 March 2012 (UTC)
replies: text: I agree, any Greek or Latin letter could be used as a "variable in algebraic equations", and the entry contains no blue links, so I have been bold and deleted it. -- Dr Greg  talk  19:54, 13 March 2012 (UTC)

message: The Greek letter ∂ (curly small delta) plays an important role in mathematics and physics, one notable place is calculus, where it is used to denote partial derivative, such as \frac{\partial^2}{\ \partial x\  \partial y\ }. However, this letter is missing from the table of Greek letters in this article. Therefore, I suggest that it be inserted there as follows (showing only the part of the table for letter delta):

I suggest that one of the more-frequent editors of this page or this topic should make this change in order to avoid controversy, as I am relatively unknown. Alternatively, I would be happy to make the change myself, provided that no one objected.

replies: text: I'm not convinced that character is a "Greek delta" at all. The Wikipedia article ∂ makes no mention of "Greek" or "delta"; it calls it a "curly dee", not "curly delta"; in Unicode it is called "partial differential"; in LATEX it's called "\partial"; and in HTML it's called "∂" -- Dr Greg  talk  01:21, 7 October 2014 (UTC)
