Testing testing, $1, 2$!

If I'm going to be a blogger, I will certainly talk about mathematics from time to time. Fortunately, there is something called MathJax that allows me to type equations in LaTeX just like I'm used to, and have them displayed here. For instance I might want to talk about the cardinal number $\aleph_\omega$, or the identity \[\sum_{k=1}^\infty \frac1{k^2} = \frac{\pi^2}6.\]

Seems to work!
