One of the saints in my life is this woman named Imogene Hill, who was a fourth-grade teacher who taught this advanced class. She got hip to my whole situation in about a month and kindled a passion in me for learning things. I learned more that year than I think I learned in any year in school.

Ultimately, it’s a man who was teaching us English Literature in what we call matricula, the last 2 years of high school. He really was quite extraordinary. When he spoke of a Shakespearean play, you almost thought that he grew up with Shakespeare! He was very good, yes. A black guy who was fantastic and gave us a deep love for literature.

At this school I was allowed to learn things which interested me: French, History, lots of Poetry by heart, and above all Riding and Swimming. The impression of those years makes a pleasant picture in my mind, in strong contrast to my earlier schoolday memories.

I wanted to know. I asked a lot of questions and she would say, "Read, read."…So she inspired me a great deal.

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.

Then I had another thought: Physics disgusts me a little bit now, but I used to enjoy doing physics.  Why did I enjoy it?  I used to play with it.  I used to do whatever I felt like doing—it didn’t have to do with whether it was important for the development of nuclear physics, but whether it was interesting and amusing for me to play with.

So I wish to you—I have no more time, so I have just one wish for you—the good luck to be somewhere where you are free to maintain the kind of integrity I have described, and where you do not feel forced by a need to maintain your position in the organization, or financial support, or so on, to lose your integrity. May you have that freedom. May I also give you one last bit of advice: Never say that you'll give a talk unless you know clearly what you're going to talk about and more or less what you're going to say.

I had nothing to do, so I start to figure out the motion of the rotating plate.  I discover that when the angle is very slight, the medallion rotates twice as fast as the wobble rate—two to one.  It came out of a complicated equation!  Then I thought, “Is there some way I can see in a more fundamental way, by looking at the forces or the dynamics, why it’s two to one?”

It is necessary, I believe, to accept this idea, not only for science, but also for other things; it is of great value to acknowledge ignorance.  It is a fact that when we make decisions in our life we don't necessarily know that we are making them correctly; we only think that we are doing the best we can – and that is what we should do.

I don’t believe I can really do without teaching.  The reason is, I have to have something so that when I don’t have any ideas and I’m not getting anywhere I can say to myself, “At least I’m living; at least I’m doing something; I’m making some contribution”—it’s just psychological.
