Formatting inline math

[edit]

I reduced the size of the inline math using \scriptstyle. I know it creates problems with some of the characters, but overall I think the article looks better. However, if you don't like it feel free to reverse it. Here is a comparison of some choices using different approaches:

  1. (display LaTex) The second of de Bruijn's results concerns the case in which each side of the brick is a multiple of the next smaller side: there exists a sequence of numbers such that , , , and more generally .
  2. (scriptstyle LaTeX) The second of de Bruijn's results concerns the case in which each side of the brick is a multiple of the next smaller side: there exists a sequence of numbers such that , , , and more generally .
  3. ({{math}} template) The second of de Bruijn's results concerns the case in which each side of the brick is a multiple of the next smaller side: there exists a sequence of numbers c1,c2, ... cd such that a1=c1, a2=c1c2, a3 = c1c2c3, and more generally

I cheated and broke out the product symbol on a separate line because it's hard to implement with {{math}}. RockMagnetist (talk) 02:34, 30 August 2012 (UTC)[reply]

I have mathjax turned on in my user preferences; apparently, from your examples, using \scriptstyle makes no difference there (perhaps it recognizes math in inline text and turns on scriptstyle automatically in that case?) However, using {{math}} looks significantly worse to me. —David Eppstein (talk) 03:52, 30 August 2012 (UTC)[reply]
I tried turning on mathjax and get a similar result. I think I tried mathjax some time ago and got some real messes; maybe it has since been improved. However, a lot of people won't have it turned on, so you might want to experiment with turning it off temporarily. If the LaTeX environment always looked better, I would happily abandon {{math}}.

When mathjax first became available, there was a severe bug that made it impossible to use ampersands or less than signs in math. That has since been fixed, though. Now the worst remaining problem I know about is some extra cruft it adds to the end of a {{citation}} or {{cite journal}} template if you try to use <math> within a title. Anyway, thanks for improving the default appearance. —David Eppstein (talk) 04:17, 30 August 2012 (UTC)[reply]
There are also examples where some symbols overlap each other (see equation 10 in Demagnetizing field). You're welcome. RockMagnetist (talk) 04:42, 30 August 2012 (UTC)[reply]

Name of theorem

[edit]

Shouldn't it be de Bruijn's theorem? RockMagnetist (talk) 04:43, 30 August 2012 (UTC)[reply]

My understanding of the Dutch name particles like "de" is that they are capitalized the same as most English words: lower case in the middle of a sentence, capitalized at the start of a sentence (or the start of an article's title). —David Eppstein (talk) 05:47, 30 August 2012 (UTC)[reply]
I think that is probably right. I have corrected a couple in the middles of sentences. RockMagnetist (talk) 05:48, 30 August 2012 (UTC)[reply]
