Do I have a muse? Well, I don’t know if this is an adequate answer, but I suppose my muse is the people of South Africa. I’ve often said that the little — or maybe the lot — I know about loving and hating was taught me by South Africa. Now that’s a big debt. When you owe that much to a situation that has shaped your conscience, your heart, your whole life, you’re profoundly indebted.

People tell me that I work hard. I never feel that I do particularly, because it’s fun. I always say, “Well, I’ve never worked hard in my life.” I’m busy, but most of what I do is enjoyable. It isn’t that it’s not tedious to some people, and so on, and of course I have routine to do, but I don’t mind it. I just don’t feel that I’m put upon. I spend a lot of time, but it’s fun. It’s a very intensive hobby. I would say it’s my most serious hobby. I have lots of hobbies, but the one permanent one is science, physics. So yes, I spend a lot of time, and I would agree with Edison, you have to work very hard and intensively.

Yes. Because in the end, experience is what counts. The more experience you have, the better you are. And that’s true of anything you do in airplanes, dogfighting in combat, or anything like that. Your chances of coming out on top depend on your experience level. The more experience you can get, the better chance you have of surviving in a war, or in any situation where you are faced with an emergency.

Yes, that’s right. I saw what I could succeed in. I never considered myself very bright, and I always thought of myself as mathematically mediocre. So I figured that probably, like your college runner who has difficulty breaking a ten-second hundred — well, breaking an 11-second, shall we say, 100-meter — realizes that their best shot is to rely less on strength and speed and more on self-discipline, planning, and long hard work. Yes. That’s the way I do science.
