We do plenty of math, so I’d like to test out MathJax support.

Here is an example of MathJax inline rendering — $$1/x^{2}$$. And here is a block rendering: $r_{XY} = \frac{\mathrm{cov}(X,Y)}{\sqrt{\mathrm{var}(X)\mathrm{var}(Y)}}$

Now, if we’d like to get serious, we’d do something involving multiline aligned equations, like \begin{align} \mathcal{N}(t, \mu, \sigma) &= \mathrm{normal} \newline &= \frac{1}{\sqrt{2 \pi} \sigma} e^{-\frac{(t-\mu)^2}{2 \sigma^2}} \end{align} or even an inline formula like $$\sum_{t=0}^{\infty} \frac{x^t}{t!} = e^x$$.

Or we could try defining a command, like this. $$\newcommand{\water}{\mathrm{H}_{2}\mathrm{O}}$$

Buffer slides off the sides of our tubes like $$\water$$ off a duck’s back.
