Math on this blog

July 27, 2026 · 1 min read

This blog now supports math, rendered at build time to native MathML: no JavaScript, no images, no fonts shipped to you unless a page actually uses math.

How it works: posts are written with LaTeX in the markdown, and a small post-build step converts every formula into a native <math> element using Temml. Your browser renders it like any other text: selectable, accessible, and styled by CSS. Very 1998 in spirit: the server does the work, the client just displays a document.

Inline math like $E = m c^{2}$ sits nicely in a sentence, and so does something with subscripts like $x_{n + 1} = x_{n} - \frac{f (x_{n})}{f^{'} (x_{n})}$ .

Display math gets its own block:

x = \frac{- b \pm \sqrt{b^{2} - 4 a c}}{2 a}

Even bigger stuff works, like matrices:

(\begin{matrix} \cos θ & - \sin θ \\ \sin θ & \cos θ \end{matrix}) (\begin{matrix} x \\ y \end{matrix}) = (\begin{matrix} x \cos θ - y \sin θ \\ x \sin θ + y \cos θ \end{matrix})

And sums and integrals:

\int_{0}^{\infty} e^{- x^{2}} d x = \frac{\sqrt{π}}{2} \sum_{n = 1}^{\infty} \frac{1}{n^{2}} = \frac{π^{2}}{6}

A regular code span like let x = 42; is left untouched, and so are fenced code blocks in other languages.
