Mathematical notation on Wikipedia

Hello. Please look at my several edits to Ehrenfest theorem. Note that there is no need to use "<" and ">" for angle brackets in TeX; instead of writing

$<A>\,$

you can write

$\langle A\rangle .\,$

If adjustability of size is needed you can use \left\langle and \right\rangle, thus:

$\left\langle {A \over B}\right\rangle .$

Also, on Wikipedia it is conventional to indent "displayed" TeX with an invisible colon, thus

$\int _{-\infty }^{\infty }1\,dx,$

and not thus:

$\int _{-\infty }^{\infty }1\,dx,$

(If the paragraph is already indented, then one should use two colons for "displayed" TeX.)

Also, in non-TeX mathematical notation, one italicizes variables (but not parentheses or digits), thus: n + m = 2. Notice I've used the non-breakable "nbsp" space character before and after "+" and before and after "="; this looks better than n+m=2 (with no spaces between characters).

Also, in section headings, the first letter should be capitalized, but later initial letters should be capitalized only if there's some other reason for it than being a section heading. Thus one writes "External links" with a lower-case "l", not "External Links" with a capital "L" (see Wikipedia:Manual of Style).

Happy editing. Michael Hardy 19:31, 28 October 2005 (UTC)

... same thing with Hanbury-Brown and Twiss effect. Michael Hardy 19:41, 28 October 2005 (UTC)

Welcome and other remarks

I notice that no one had welcomed you before, so I inserted the standard welcome notce at the top. Thanks for Hanbury-Brown and Twiss, and I see you've made a number of excellent edits to other articles. Thanks! I strongly invite you to participate in the Wikipedia:WikiProject Physics and in particular the discussions at Wikipedia talk:WikiProject Physics. There is also an older and considerably more actve Wikipedia:WikiProject Mathematics that you might also be interested in. linas 16:56, 23 November 2005 (UTC)
