Randall Munroe, that is.
It was just a thought that came to me reading today's xkcd comic.
They guy is trained in physics just down the road from my alma mater, worked on robots a while, and then got into web comics. But his mind is such that he's curious enough to look into the minutiae of human vision... and then write a comic about it.
Intellecutal curiosity is a really beautiful thing. Econosphere bloggers and xkcd readers are of course often in their own bubble as far as intellectual curiousity. After all, different people have different capacities to explore the unknown. Some of these capacities are probably biological and a lot are socially determined. But aside from those issues and constraints, anybody can be curious. A lack of curiosity in a person is one of the saddest things to see.
Just a thought I had when reading the comic.
