This is more grokable for the average geek than most, but I think he was looking for a less mathematically jargon-y translation. E.g., something like[1] this written to translate from the "math" domain into the "average dude" domain, done by the co-founder of Julia. R_8 / R_24 is still impressive, haters. ;)

We both might know enough about math to know what a Lebesgue measure is, but Real Analysis wasn't a requirement for most CS majors posting on here I'd imagine. (I agree with my uncle/aunt poster, though-- this is way more accessible to the general mathematician than a Wiles on Fermat or Perelman on Poincare. It's self-contained enough to clearly define * weakly-holomorphic modular form* [which I could take a stab at, but not with too high of a confidence factor]. Spending a few minutes to throw (19) in there was kind of the author to do, so those from other disciplines of mathematics could continue reading instead of just presuming what \gamma was.)
