I think Greg's 'biologists' are a special subset of biologists. As I see it CP Snow was right about the two cultures. But within science there are also two cultures, one of whom speaks mathematics and the other that speaks organic chemistry. Speaker of organic chemistry share a view that enough lab work and enough data will answer all the questions. They don't need no silly equations.

In our field the folks who speak mathematics tend to view the lab rats as glorified techs. This is certain not right but it is there and leads to a certain amount of mutual disdain.

This kind of mutual disdain is apparently just not there in physics between the theoretical and experimental physics people. I wish evolutionary biology were more like physics.
