Hard to be a physics major at Rice University if you have flunked calculus.

My first degree came years before my second. I had wanted to be a physicist, but I flunked calculus.

It's hard to hold the focus that strongly on a single character for that long.

I was always very strong in math, physics and calculus.

So when I got out of the military, I went back to school in biology, and earned a biology degree at the University of Texas, and then did some graduate work in it.

I love biomedical science, I love astronomy, and you can't really do much with those in a fantasy setting.
