On learning from "doing the math"

In case you have been living under a rock (yet inexplicably reading this blog) Usain Bolt has now run both the 100 meter and 200 meter track events faster than anyone ever. The margin of improvement in the 100 meter event (which occurred earlier) was sufficient to start the sports world abuzz. Naturally, sports fans are willing to talk endlessly about the most absurd minutia and implications of such an event in terms pedestrian and embarrassingly overwrought.
YHN is no different.
