It's easy to do italics or make things bold.

All models are wrong, but some are useful. An approximate answer to the right problem is worth a good deal more than an exact answer to an approximate problem. Absolute certainty is a privilege of uneducated minds-and fanatics. It is, for scientific folk, an unattainable ideal. What you do every day matters more than what you do once in a while. We cannot expect anyone to know anything we didn't teach them ourselves. Enthusiasm is a form of social courage.

I can haz equations. Inline equations, such as ... the average is computed as $\frac{1}{n} \sum_{i=1}^{n} x_{i}$. Or display equations like this:

$$ \begin{equation*} |x|= \begin{cases} x & \text{if $x≥0$,} \\\ -x &\text{if $x\le 0$.} \end{cases} \end{equation*} $$
