Markdown latex compatibility

[radualexe32]

Would be great if in the journal notes we could add math annotations via markdown latex similar to the markdown here on github (e.g. $\epsilon_t \sim \mathcal{N}(0, \sigma^2$)).

This would be especially useful when jotting down notes and thoughts in the journal about papers, or textbook that some of us in the AI space are making.
