Computations for This World and out of This World

In many ways, my career has been chasing chances to do mathematics. When I enrolled at college, I majored in math. Later, I added a second major, chemical physics, which seemed to offer better career options than pure mathematics. When I was accepted to graduate programs for mathematics and chemical physics, I moved into chemical physics. One nice aspect of chemical physics is that it seems to be 80% physics and 20% math.
