I liked mathematics. I liked biology. I didn’t like chemistry quite as much, because it was — at that time I was taught a kind of cookbook type of chemistry, not the exciting chemistry which is current today. But physics had so much logic in it. Such firm, demanding logic. One could really figure things out. That particularly attracted me. But I liked the other sciences too. However, at some point I had to decide. Actually, I didn’t decide until fairly late. The first course of physics I took was as a sophomore in college. And it was only the end of that year that I decided, “Yes, physics really is what I think I really want to do.” I would have been very happy in biology or some other sciences too, I’m sure.
