My parents must have done a great job. Anytime I wanted to pursue something that they weren't familiar with, that was not part of their lifestyle, they let me go ahead and do it.

It's well known that many girls have a tendency to dumb down when they're in middle school.

I liked math - that was my favorite subject - and I was very interested in astronomy and in physical science.
