MathJax 2.0, probably the nicest way for showing/writing math on the Web

AFAIK, it is the only one. True?

  There's also TeX the World, although that is no longer under development and probably should not be used. Wordpress.com has some kind of support for math in blogs. I don't know how they actually implement it.

Someone on Reddit wrote a nice bookmarklet to use MathJax on pages where the site doesn't support it. You can get the bookmarklet here: http://web.mit.edu/jcalz/Public/Reddit/mathbookmarklet.html http://web.mit.edu/jcalz/Public/Reddit/mathbookmarklet.html Here was the Reddit discussion: http://www.reddit.com/r/math/comments/o6a2u/math_bookmarklet_tex_the_world_mathjax/ http://www.reddit.com/r/math/comments/o6a2u/math_bookmarklet... It supports both MathJax and TeX the World, which is what /r/math uses. However, that is no longer being developed, so for sites other than /r/math I think people should stick to MathJax. The great thing about the bookmarklet approach is that it also works great on mobile devices. The previous solution for adding math to sites where the site owner won't support it was to use a greasemonkey plug-in or something similar, which generally left out mobile. Here's some math if anyone wants something to try out with the bookmarklet. The solutions of $a x^2+ b x + c = 0$ are: $$x = {{-b\pm\sqrt{b^2-4ac}}\over{2a}}$$ Another example. Consider the continued fraction expansion of an arbitrary real number $\alpha$:$$\alpha=a_0+{1\over{a_1+{1\over{a_2+{1\over{a_3+...}}}}}}$$. Let $\left\{p_n\over{q_n}\right\}$ be the sequence of convergents for this continued fraction. For almost all real $\alpha$, the limit as $n\to\infty$ of $q_n^{1/n}$exists and $$\lim_{n\to\infty}{q_n^{1/n}}=e^{\pi^2\over{12 \log 2}}$$ For the curious, more information on that interesting limit can be found here: http://mathworld.wolfram.com/Khinchin-LevyConstant.html http://mathworld.wolfram.com/Khinchin-LevyConstant.html

There is a css/js dropin for wikipedia under development here: http://en.wikipedia.org/wiki/User:Nageh/mathJax http://en.wikipedia.org/wiki/User:Nageh/mathJax It is phenomenal on wikipedia pages. Sadly it does not support wikibooks at the moment.
