invite me to be a professor there! And not just a regular professor. Somehow they knew my feelings about the Institute: how it's too theoretical; how there's not enough real activity and challenge. So they write, "We appreciate that you have a considerable interest in experiments and in teaching, so we have made arrangements to create a special type of professorship, if you wish: half professor at Princeton University, and half at the Institute." Institute for Advanced Study! Special exception! A position better than Einstein, even! It was ideal; it was perfect; it was absurd! It was absurd. The other offers had made me feel worse, up to a point. They were expecting me to accomplish something. But this offer was so ridiculous, so impossible for me ever to live up to, so ridiculously out of proportion. The other ones were just mistakes; this was an absurdity! I laughed at it while I was shaving, thinking about it. And then I thought to myself, "You know, what they think of you is so fantastic, it's impossible to live up to it. You have no responsibility to live up to it!" It was a brilliant idea: You have no responsibility to live up to what other people think you ought to accomplish. I have no responsibility to be like they expect me to be. It's their mistake, not my failing. It wasn't a failure on my part that the Institute for Advanced Study expected me to be that good; it was impossible. It was clearly a mistake and the moment I appreciated the possibility that they might be wrong, I realized that it was also true of all the other places, including my own university. I am what I am, and if they expected me to be good and they're offering me some money for it, it's their hard luck. Then, within the day, by some strange miracle perhaps he overheard me talking about it, or maybe he just understood me Bob Wilson, who was head of the laboratory there at Cornell, called me in to see him. He said, in a serious tone, "Feynman, you're teaching your classes well; you're doing a good job, and we're very satisfied. Any other expectations we might have are a matter of luck. When we hire a professor, we're taking all the risks. If it conies out good, all right. If it doesn't, too bad. But you shouldn't worry about what you're doing or not doing." He said it much better than that, and it released me from the feeling of guilt. 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. When I was in high school, I'd see water running out of a faucet growing narrower, and wonder if I could figure out what determines that curve. I found it was rather easy to do. I didn't have to do it; it wasn't important for the future of science; somebody else had already done it. That didn't make any difference: I'd invent things and play with things for my own entertainment. So I got this new attitude. Now that I am burned out and I'll never accomplish anything, I've got this nice position at the university teaching classes which I rather enjoy, and just like I read the Arabian Nights for pleasure, I'm going to play with physics, whenever I want to, without worrying about any importance whatsoever. Within a week I was in the cafeteria and some guy, fooling around, throws a plate in the air. As the plate went up in the air I saw it wobble, and I noticed the red medallion of Cornell on the plate going around. It was pretty obvious to me that the medallion went
around faster than the wobbling. 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?" I don't remember how I did it, but I ultimately worked out what the motion of the mass particles is, and how all the accelerations balance to make it come out two to one. I still remember going to Hans Bethe and saying, "Hey, Hans! I noticed something interesting. Here the plate goes around so, and the reason it's two to one is. . ." and I showed him the accelerations. He says, "Feynman, that's pretty interesting, but what's the importance of it? Why are you doing it?" "Hah!" I say. "There's no importance whatsoever. I'm just doing it for the fun of it." His reaction didn't discourage me; I had made up my mind I was going to enjoy physics and do whatever I liked. I went on to work out equations of wobbles. Then I thought about how electron orbits start to move in relativity. Then there's the Dirac Equation in electrodynamics. And then quantum electrodynamics. And before I knew it (it was a very short time) I was "playing" working, really with the same old problem that I loved so much, that I had stopped working on when I went to Los Alamos: my thesistype problems; all those old fashioned, wonderful things. It was effortless. It was easy to play with these things. It was like uncorking a bottle: Everything flowed out effortlessly. I almost tried to resist it! There was no importance to what I was doing, but ultimately there was. The diagrams and the whole business that I got the Nobel Prize for came from that piddling around with the wobbling plate. Any Questions? When I was at Cornell I was asked to give a series of lectures once a week at an aeronautics laboratory in Buffalo. Cornell had made an arrangement with the laboratory which included evening lectures in physics to be given by somebody from the university. There was some guy already doing it, but there were complaints, so the physics department came to me. I was a young professor at the time and I couldn't say no very easily, so I agreed to do it. To get to Buffalo they had me go on a little airline which consisted of one airplane. It was called Robinson Airlines (it later became Mohawk Airlines) and I remember the first time I flew to Buffalo, Mr. Robinson was the pilot. He knocked the ice off the wings and we flew away. All in all, I didn't enjoy the idea of going to Buffalo every Thursday night. The university was paying me $35 in addition to my expenses. I was a Depression kid, and I figured I'd save the $35, which was a sizable amount of money in those days. Suddenly I got an idea: I realized that the purpose of the $35 was to make the trip to Buffalo more attractive, and the way to do that is to spend the money. So I decided to
