That moving a lot really committed me to stability and committed me to ... being in control of my destiny. That was something that was very important to me. And it also made me very conservative about money.

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.

Well, you’re right, I think the hard work definitely paid off. My grandmother drove me three hours to dance and three hours back from age six to age 11. I would do my school work in the car on the way there and then get home at like 11 o’clock at night, five days a week for many years. My training was seriously intense, and nothing came easy. I worked for everything I’ve ever been given.

I did it because that’s what it was going to take. I really wanted it. I had an older brother, and he was bigger and smarter, and when you’re a kid, you’re trying to catch up all the time. I think that that’s where it kind of came from, just that little brother syndrome. I was just trying to be something, trying to make myself worth something. It was proving it to other people and proving it to myself at the same time. I needed that.

Then there was Von Neumann, the great mathemati-cian. We used to go for walks on Sunday. We'd walk in the canyons, and we'd often walk with Bethe, and Von Neumann, and Bacher. It was a great pleasure. And Von Neumann gave me an interesting idea; that you don't have to be responsible for the world that you're in.

the colonel said I shouldn't tell them how the neutrons work and all the details because we want to keep things separate, so just tell them what to do to keep it safe.

I would like to add something that’s not essential to the science, but something I kind of believe, which is that you should not fool the layman when you’re talking as a scientist.

The first principle is that you must not fool yourself—and you are the easiest person to fool. So you have to be very careful about that. After you've not fooled yourself, it's easy not to fool other scientists. You just have to be honest in a conventional way after that.

For example, I was a little surprised when I was talking to a friend who was going to go on the radio. He does work on cosmology and astronomy, and he wondered how he would explain what the applications of this work were. "Well," I said, "there aren't any." He said, "Yes, but then we won't get support for more research of this kind." I think that's kind of dishonest. If you're representing yourself as a scientist, then you should explain to the layman what you're doing—and if they don't want to support you under those circumstances, then that's their decision.

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