Dennis Overbye at the New York Times today asks whether science and Wall Street is really such a good mix.

Some of my former physics colleagues have taken their skills to the world of finance over the years. I think they were surprised there wasn't more math on Wall Street, but also wary of how useful that math would be.

This quote kind of sums things up:

"In physics there may one day be a Theory of Everything; in finance and the social sciences, you're lucky if there is a useable theory of anything."
