Adding MathJAX with LaTeX and MathML support to Jekyll
Pages, Numbers, and Keynote gots updates today with LaTeX and MathML support, and it reminded me that I wanted to add to my blog here. I always wanted to do this ever since I saw what was I think Dr. Drang’s MathJax post. Enter MathJax!
Configuring jekyll
Heavily borrowing from Adding MathJax to a GitHub Pages Jekyll Blog, it was a quick task to add. The main changes to repo:
_includes/mathjax.html
assets/js/MathJaxLocal.js
_layouts/posts.html
The first two are new files1’2 including the necessary javascript code and customization for MathJax. And the _layouts/posts.html edit is to embed the javascript into the jekyll-rendered post page.

Examples
These are my favorite part.
Newton’s law of universal gravitation
\[F = G \frac{m_1 m_2} {r^2}\]$$ F = G \frac{m_1 m_2} {r^2} $$
Einstein field equations
\[R_{\mu \nu} - \frac{1} {2}Rg_{\mu \nu} + \Lambda g_{\mu \nu} = \frac{8\pi G} {c^4}T_{\mu \nu}\]$$ R_{\mu \nu} - \frac{1} {2}Rg_{\mu \nu} + \Lambda g_{\mu \nu} = \frac{8\pi G} {c^4}T_{\mu \nu} $$
