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 thesis-type 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 spend the $35 to entertain myself each time I went to Buffalo, and see if I could make the trip worthwhile.
I didn’t have much experience with the rest of the world. Not knowing how to get started, I asked the taxi driver who picked me up at the airport to guide me through the ins and outs of entertaining myself in Buffalo. He was very helpful, and I still remember his name—Marcuso, who drove car number 169. I would always ask for him when I came into the airport on Thursday nights.
As I was going to give my first lecture I asked Marcuso, “Where’s an interesting bar where lots of things are going on?” I thought that things went on in bars.
“The Alibi Room,” he said. “It’s a lively place where you can meet lots of people. I’ll take you there after your lecture.”
After the lecture Marcuso picked me up and drove me to the Alibi Room. On the way, I say, “Listen, I’m go
“Ask for Black and White, water on the side,” he counseled.
The Alibi Room was an elegant place with lots of people and lots of activity. The women were dressed in furs, everybody was friendly, and the phones were ringing all the time.
I walked up to the bar and ordered my Black and White, water on the side. The bartender was very friendly quickly found a beautiful woman to sit next to me, and introduced her. I bought her drinks. I liked the place and decided to come back the following week.
Every Thursday night I’d come to Buffalo and be driven in car number 169 to my lecture and then to the Alibi Room. I’d walk into the bar and order my Black and White, water on the side. After a few weeks of this it got to the point where as soon as I would come in, before I reached the bar, there would be a Black and White, water on the side, waiting for me. “Your regular, sir,’ was the bartender’s greeting.
I’d take the whole shot glass down at once, to show I was a tough guy, like I had seen in the movies, and then I’d sit around for about twenty seconds before I drank the water. After a while I didn’t even need the water.
The bartender always saw to it that the empty chair next to mine was quickly filled by a beautiful woman, and everything would start off all right, but just before the bar closed, they all had to go off somewhere. I thought it was possibly because I was getting pretty drunk by that time.
One time, as the Alibi Room was closing, the girl I was buying drinks for that night suggested we go to another place where she knew a lot of people. It was on the second floor of some other building which gave no hint that there was a bar upstairs. All the bars in Buffalo had to close at two o’clock, and all the people in the bars would get sucked into this big hall on the second floor, and keep right on going—illegally, of course.
I tried to figure out a way that I could stay in bars and watch what was going on without getting drunk. One night I noticed a guy who had been there a lot go up to the bar and order a glass of milk. Everybody knew what his problem was: he had an ulcer, the poor fella. That gave me an idea.
The next time I come into the Alibi Room the bartender says, “The usual, sir?”
“No. Coke. Just plain Coke,” I say, with a disappointed look on my face.
The other guys gather around and sympathize: “Yeah, I was on the wagon three weeks ago,” one says. “It’s really tough, Dick, it’s really tough,” says another.
They all honored me. I was “on the wagon” now, and had the guts to enter that bar, with all its “temptations,” and just order Coke—because, of course, I had to see my friends. And I maintained that for a month! I was a real tough bastard.
One time I was in the men’s room of the bar and there was a guy at the urinal. He was kind of drunk, and said to me in a mean-sounding voice, “I don’t like your face. I think I’ll push it in.”
I was scared green. I replied in an equally mean voice, “Get out of my way, or I’ll pee right through ya!”
He said something else, and I figured it was getting pretty close to a fight now. I had never been in a fight. I didn’t know what to do, exactly, and I was afraid of getting hurt. I did think of one thing: I moved away from the wall, because I figured if I got hit, I’d get hit from the back, too.
