Resources for PhD Students, a very large link page by Prof. Li at Cornell.
A lot of non-mathy people have not physics envy, but physicist envy. They think there's too much math in economics, but also think that physicists are really really smart and wise, way more than economists, and physicists never write silly papers. But physicists are just people too, though, like people with a PhD in economics, the need to learn a lot of math means that they all do have much higher IQ's than the general population.
