Paper: Frequentism and Bayesianism: A Python-driven Primer (Jake VanderPlas)

This is the final version – ready to be reviewed.
I suggest you add one more intermediate step: after deriving the alpha-prime/beta-prime -> alpha/beta mappings, also show dalpha-prime/dbeta-prime->dalpha/dbeta.  You can just change the second sentence from "It then follows that ... and ...Q..." to "It then follows that ..., ..newd-stuff..., and ...Q...", so it should only add a little bit of length.

I suggest this because it won't necessarily be obvious to all readers who aren't used to thinking about probability distribution derivations that that's the intermediate step.  But with that included, I think just about anyone with the relevant math background will be able to understand what's happening, which I think fits better with the intent of the paper partly as a "teach unfamiliar people more about Bayesian statistics" theme.
