Math for the Masses

Odd as it may sound, I miss all the equations from my days in grad school, so I decided that what WordPress.com needed most was a hot, niche feature that maybe 17 people would use regularly:

\LaTeX

For those that don’t know, \LaTeX is a typesetting system particularly well suited for documents of a mathematical persuasion. It’s used almost exclusively by many technical, scientific and mathematical disciplines both in academia and industry. It also looks really good; I, among many, consider Donald E. Knuth a personal hero.

For those that do know, it’s now ridiculously easy to include inline \LaTeX formulas in your blog posts.

The syntax is reminiscent of \LaTeX‘s inline math mode: $latex your-latex-code-here$, and it allows you to produce most any equation. For example, the following code

$latex i\hbar\frac{\partial}{\partial t}\left|\Psi(t)\right>=H\left|\Psi(t)\right>$

yields

i\hbar\frac{\partial}{\partial t}\left|\Psi(t)\right>=H\left|\Psi(t)\right>.

Pretty sweet, huh?

To further whet your appetite, these few standards show a bit more about what’s now possible on WordPress.com.

\displaystyle\bar{M}=\frac{kT}{\Xi}\sum_N\left(\frac{\partial Q_N}{\partial D}\right)_{V,T}\lambda^N

G_{ab}^{(1)} = -\frac{1}{2}\partial^c\partial_c \bar{\gamma}_{ab} + \partial^c\partial_{(b}\bar{\gamma}_{a)c} -\frac{1}{2}\eta_{ab}\partial^c\partial^d\bar{\gamma}_{cd} = 8\pi T_{ab}

\displaystyle P_\nu^{-\mu}(z)=\frac{\left(z^2-1\right)^{\frac{\mu}{2}}}{2^\mu \sqrt{\pi}\Gamma\left(\mu+\frac{1}{2}\right)}\int_{-1}^1\frac{\left(1-t^2\right)^{\mu -\frac{1}{2}}}{\left(z+t\sqrt{z^2-1}\right)^{\mu-\nu}}dt

\square

UPDATE: There’s a new LaTeX on WordPress.com FAQ entry that describes the “hidden” size and color options.

    On another note, we are experiencing far less spam this past week at our blog and it seems that something has been done to calm things and catch it earlier on. (?)

    Anyway, just wanted to stop by and thank Matt and the team for their continued energies.

    As a lifelong arithmophobe, I get hives just looking at what this font can do. Math was actually bearable when it entailed numbers only, but in sixth grade, when letters, strange signs, and superscript came into the equation — no pun intended — that’s when I freaked out on the subject. LOL It is objectively pretty, though, like font art. Enjoy your niche! You definitely found one judging from the comments above.

    I’m somewhat surprised that you didn’t just implement the jsMath library. I’ve been using it on Road Sign Math for a long time and it works really well. However, this implementation seems really nice as well.

    Any chance this is going to be a wp-plugin soon for people that are running WordPress locally? Would be a nice thing to have. I realize there is the LaTeX Renderer plugin, but this seems to be a superior implementation.
