It so happened that we had a very good math teacher, who was a Communist. I remember having learned from him something that I never forget: the rule of nines. A simple point: you add up the numerals in a number, and if the original number was divisible by nine, then the sum of the figures also is. For instance, you take a number like 243. Two and four and three is nine. Therefore, 243 must be divisible by nine. Actually it is nine times 27. The rule is interesting because it’s so simple. What was really interesting to us ten-year-olds is that our math teacher proved it. The proof is not terribly difficult, but it was one of the first simple and not quite obvious mathematical proofs that I encountered.

My parents inspired me by their example. They both grew up in the Depression, and both of them had to quit school when they were quite young to work, because there actually was no choice. So, though they’re intelligent people — and my father in particular is interested in books and has subsequently, since his retirement, attended classes at the University of Buffalo — nonetheless, they didn’t have any opportunity to be educated. So they’ve always impressed me with their resilience, their good spirits, their courage. It wasn’t an easy life, and I won’t go into details, but there were a lot of problems. And yet they were never defeated. Somebody else might have been defeated. Someone else might have been really depressed, or become an alcoholic or something, because there were personal problems and economic crises. But I just remember them carrying on and just doing their lives. They really made a strong impression on me.

He was a little guy who was a great football player at Georgia Tech, and he just was indefatigable. He just would never, ever say die. He absolutely proved to me that persistence was a very big part of making it in life. I never forgot that lesson.

We'd walk in the canyons, and we'd often walk with Bethe, and Von Neumann, and Bacher. It was a great pleasure.

My father said to me, “You need a piece of paper to go into a door sometimes.” I didn’t understand about résumés, but when you write a résumé you have to put down things that people want to know about.

I was the first black in that particular league. And, we played in a town called Hagerstown, Maryland. ... I said to myself — and this is why Piper Davis came in — in my mind, “Hey, whatever they call you, they can’t touch you. Don’t talk back.”
