From Guys Just Want to Have Fun

The intro:

When I was in college, I followed a simple strategy: Go where the boys are. Sure, that led me into many settings where inebriants flowed, but my reasoning was strictly practical. Men ruled the world, as anyone could see, so the trick was to do as they did. No girlie major like art history or French lit for me. I started in chemistry and then proceeded up the gender gradient to physics, finally achieving in Classical Mechanics the exalted status of only girl in the class.

And the conclusion:

I'd still major in physics if I were doing it again, just because there ought to be at least a few Americans, of whatever gender, who know something beyond the technology of beer bongs.
