I think that girls do self-select themselves out to some extent, but I think that at the top level that there are more men with the mental disease that makes them a good mathematician (or something closely related) than women. But nice to hear that there are some female degenerates like yourself. :)
I'm sure it's complete nonsense, but I happen to believe that the "bell curve" for women has a smaller variance than the one for men when it comes to mathematics. So, when you get to the genious mathematician level (or the mentally challenged level) you tend to see more men.
I did plan to major in Biology, due to the enjoyment I had in high school (girls' school, no less). HOWEVER, the labs bored me out of my mind, so I broke off the idea of majoring in anything with labs!! I do like to read about physics.

Interesting insight. [My girlfriends and I who were "good" in math after all didn't win any Nobel prizes for theoretical mathematics! ;) ]
