“Surely You’re Joking, Mr. Feynman”: Adventures of a Curious Character

by Richard Phillips Feynman

  A week later we went to the rehearsal and found there was a new drummer there—the regular drummer had quit the band to do something else—and we introduced ourselves to him:

  “Hi. We’re the guys who are going to be on stage for the Havana scene.”

  “Oh, hi. Let me find the scene here …” and he turned to the page where our scene was, took out his drumming stick, and said, “Oh, you start off the scene with …” and with his stick against the side of his drum he goes bing, bong, ban g-a-bang, bing-a-bing, bang, bang at full speed, while he was looking at the music! What a shock that was to me. I had worked for four days to try to get that damn rhythm, and he could just patter it right out!

  Anyway, after practicing again and again I finally got it straight and played it in the show. It was pretty successful: Everybody was amused to see the professor on stage playing the bongos, and the music wasn’t so bad; but that part at the beginning, that had to be the same: that was hard.

  In the Havana nightclub scene some of the students had to do some sort of dance that had to be choreographed. So the director had gotten the wife of one of the guys at Caltech, who was a choreographer working at that time for Universal Studios, to teach the boys how to dance. She liked our drumming, and when the shows were over, she asked us if we would like to drum in San Francisco for a ballet.

  “WHAT?”

  Yes. She was moving to San Francisco, and was choreographing a ballet for a small ballet school there. She had the idea of creating a ballet in which the music was nothing but percussion. She wanted Ralph and me to come over to her house before she moved and play the different rhythms that we knew, and from those she would make up a story that went with the rhythms.

  Ralph had some misgivings, but I encouraged him to go along with this adventure. I did insist, however, that she not tell anybody there that I was a professor of physics, Nobel Prize-winner, or any other baloney. I didn’t want to do the drumming if I was doing it because, as Samuel Johnson said, If you see a dog walking on his hind legs, it’s not so much that he does it well, as that he does it at all. I didn’t want to do it if I was a physics professor doing it at all; we were just some musicians she had found in Los Angeles, who were going to come up and play this drum music that they had composed.

  So we went over to her house and played various rhythms we had worked out. She took some notes, and soon after, that same night, she got this story cooked up in her mind and said, “OK, I want fifty-two repetitions of this; forty bars of that; whatever of this, that, this, that …”

  We went home, and the next night we made a tape at Ralph’s house. We played all the rhythms for a few minutes, and then Ralph made some cuts and splices with his tape recorder to get the various lengths right. She took a copy of our tape with her when she moved, and began training the dancers with it in San Francisco.

  Meanwhile we had to practice what was on that tape: fifty-two cycles of this, forty cycles of that, and so on. What we had done spontaneously (and spliced) earlier, we now had to learn exactly. We had to imitate our own damn tape!

  The big problem was counting. I thought Ralph would know how to do that because he’s a musician, but we both discovered something funny. The “playing department” in our minds was also the “talking department” for counting—we couldn’t play and count at the same time!

  When we got to our first rehearsal in San Francisco, we discovered that by watching the dancers we didn’t have to count because the dancers went through certain motions.

  There were a number of things that happened to us because we were supposed to be professional musicians and I wasn’t. For example, one of the scenes was about a beggar woman who sifts through the sand on a Caribbean beach where the society ladies, who had come out at the beginning of the ballet, had been. The music that the choreographer had used to create this scene was made on a special drum that Ralph and his father had made rather amateurishly some years before, and out of which we had never had much luck in getting a good tone. But we discovered that if we sat opposite each other on chairs and put this “crazy drum” between us on our knees, with one guy beating bidda-bidda-bidda-bidda-bidda rapidly with his two fingers, constantly, the other fella could push on the drum in different places with his two hands and change the pitch. Now it would go booda— booda— booda— bidda— beeda— beeda— beeda— bidda— booda-booda-booda-badda-bidda-bidda-bidda-badda, creating a lot of interesting sounds.

  Well, the dancer who played the beggar woman wanted the rises and falls to coincide with her dance (our tape had been made arbitrarily for this scene), so she proceeded to explain to us what she was going to do: “First, I do four of these movements this way; then I bend down and sift through the sand this way for eight counts; then I stand and turn this way.” I knew damn well I couldn’t keep track of this, so I interrupted her:

  “Just go ahead and do the dance, and I’ll play along.”

  “But don’t you want to know how the dance goes? You see, after I’ve finished the second sifting part, I go for eight counts over this way.” It was no use; I couldn’t remember anything, and I wanted to interrupt her again, but then there was this problem: I would look like I was not a real musician!

  Well, Ralph covered for me very smoothly by explaining, “Mr. Feynman has a special technique for this type of situation: He prefers to develop the dynamics directly and intuitively, as he sees you dance. Let’s try it once that way, and if you’re not satisfied, we can correct it.”

  Well, she was a first-rate dancer, and you could anticipate what she was going to do. If she was going to dig into the sand, she would get ready to go down into the sand; every motion was smooth and expected, so it was rather easy to make the bzzzzs and bshshs and boodas and biddas with my hands quite appropriate to what she was doing, and she was very satisfied with it. So we got past that moment where we might have had our cover blown.

  The ballet was kind of a success. Although there weren’t many people in the audience, the people who came to see the performances liked it very much.

  Before we went to San Francisco for the rehearsals and the performances, we weren’t sure of the whole idea. I mean, we thought the choreographer was insane: first, the ballet has only percussion; second, that we’re good enough to make music for a ballet and get paid for it was surely crazy! For me, who had never had any “culture,” to end up as a professional musician for a ballet was the height of achievement, as it were.

  We didn’t think that she’d be able to find ballet dancers who would be willing to dance to our drum music. (As a matter of fact, there was one prima donna from Brazil, the wife of the Portuguese consul, who decided it was beneath her to dance to it.) But the other dancers seemed to like it very much, and my heart felt good when we played for them for the first time in rehearsal. The delight they felt when they heard how our rhythms really sounded (they had until then been using our tape played on a small cassette recorder) was genuine, and I had much more confidence when I saw how they reacted to our actual playing. And from the comments of the people who had come to the performances, we realized that we were a success.

  The choreographer wanted to do another ballet to our drumming the following spring, so we went through the same procedure. We made a tape of some more rhythms, and she made up another story, this time set in Africa. I talked to Professor Munger at Caltech and got some real African phrases to sing at the beginning (GAwa baNYUma GAwa WO, or something like that), and I practiced them until I had them just so.

  Later, we went up to San Francisco for a few rehearsals. When we first got there, we found they had a problem. They couldn’t figure out how to make elephant tusks that looked good on stage. The ones they had made out of papier mâché were so bad that some of the dancers were embarrassed to dance in front of them.

  We didn’t offer any solution, but rather waited to see what would happen when the performances came the following weekend. Meanwhile, I arranged to visit Werner Erhard, whom I had known from participating in some
conferences he had organized. I was sitting in his beautiful home, listening to some philosophy or idea he was trying to explain to me, when all of a sudden I was hypnotized.

  “What’s the matter?” he said.

  My eyes popped out as I exclaimed, “Tusks!” Behind him, on the floor, were these enormous, massive, beautiful ivory tusks!

  He lent us the tusks. They looked very good on stage (to the great relief of the dancers): real elephant tusks, super size, courtesy of Werner Erhard.

  The choreographer moved to the East Coast, and put on her Caribbean ballet there. We heard later that she entered that ballet in a contest for choreographers from all over the United States, and she finished first or second. Encouraged by this success, she entered another competition, this time in Paris, for choreographers from all over the world. She brought a high-quality tape we had made in San Francisco and trained some dancers there in France to do a small section of the ballet—that’s how she entered the contest.

  She did very well. She got into the final round, where there were only two left—a Latvian group that was doing a standard ballet with their regular dancers to beautiful classical music, and a maverick from America, with only the two dancers that she had trained in France, dancing to a ballet which had nothing but our drum music.

  She was the favorite of the audience, but it wasn’t a popularity contest, and the judges decided that the Latvians had won. She went to the judges afterwards to find out the weakness in her ballet.

  “Well, Madame, the music was not really satisfactory. It was not subtle enough. Controlled crescendoes were missing.”

  And so we were at last found out: When we came to some really cultured people in Paris, who knew music from drums, we flunked out.

  Altered States

  I used to give a lecture every Wednesday over at the Hughes Aircraft Company, and one day I got there a little ahead of time, and was flirting around with the receptionist, as usual, when about half a dozen people came in—a man, a woman, and a few others. I had never seen them before. The man said, “Is this where Professor Feynman is giving some lectures?”

  “This is the place,” the receptionist replied.

  The man asks if his group can come to the lectures.

  “I don’t think you’d like ’em much,” I say. “They’re kind of technical.”

  Pretty soon the woman, who was rather clever, figured it out: “I bet you’re Professor Feynman!”

  It turned out the man was John Lilly, who had earlier done some work with dolphins. He and his wife were doing some research into sense deprivation, and had built some tanks.

  “Isn’t it true that you’re supposed to get hallucinations under those circumstances?” I asked, excitedly.

  “That is true indeed.”

  I had always had this fascination with the images from dreams and other images that come to the mind that haven’t got a direct sensory source, and how it works in the head, and I wanted to see hallucinations. I had once thought to take drugs, but I got kind of scared of that: I love to think, and I don’t want to screw up the machine. But it seemed to me that just lying around in a sense-deprivation tank had no physiological danger, SO I was very anxious to try it.

  I quickly accepted the Lillys’ invitation to use the tanks, a very kind invitation on their part, and they came to listen to the lecture with their group.

  So the following week I went to try the tanks. Mr. Lilly introduced me to the tanks as he must have done with other people. There were lots of bulbs, like neon lights, with different gases in them. He showed me the Periodic Table and made up a lot of mystic hokey-poke about different kinds of lights that have different kinds of influences. He told me how you get ready to go into the tank by looking at yourself in the mirror with your nose up against it—all kinds of wicky-wack things, all kinds of gorp. I didn’t pay any attention to the gorp, but I did everything because I wanted to get into the tanks, and I also thought that perhaps such preparations might make it easier to have hallucinations. So I went through everything according to the way he said. The only thing that proved difficult was choosing what color light I wanted, especially as the tank was supposed to be dark inside.

  A sense-deprivation tank is like a big bathtub, but with a cover that comes down. It’s completely dark inside, and because the cover is thick, there’s no sound. There’s a little pump that pumps air in, but it turns out you don’t need to worry about air because the volume of air is rather large, and you’re only in there for two or three hours, and you don’t really consume a lot of air when you breathe normally. Mr. Lilly said that the pumps were there to put people at ease, so I figured it’s just psychological, and asked him to turn the pump off, because it made a little bit of noise.

  The water in the tank has Epsom salts in it to make it denser than normal water, so you float in it rather easily. The temperature is kept at body temperature, or 94, or something—he had it all figured out. There wasn’t supposed to be any light, any sound, any temperature sensation, no nothing! Once in a while you might drift over to the side and bump slightly, or because of condensation on the ceiling of the tank a drop of water might fall, but these slight disturbances were very rare.

  I must have gone about a dozen times, each time spending about two and a half hours in the tank. The first time I didn’t get any hallucinations, but after I had been in the tank, the Lillys introduced me to a man billed as a medical doctor, who told me about a drug called ketamine, which was used as an anesthetic. I’ve always been interested in questions related to what happens when you go to sleep, or what happens when you get conked out, so they showed me the papers that came with the medicine and gave me one tenth of the normal dose.

  I got this strange kind of feeling which I’ve never been able to figure out whenever I tried to characterize what the effect was. For instance, the drug had quite an effect on my vision; I felt I couldn’t see clearly. But when I’d look hard at something, it would be OK. It was sort of as if you didn’t care to look at things; you’re sloppily doing this and that, feeling kind of woozy, but as soon as you look, and concentrate, everything is, for a moment at least, all right. I took a book they had on organic chemistry and looked at a table full of complicated substances, and to my surprise was able to read them.

  I did all kinds of other things, like moving my hands toward each other from a distance to see if my fingers would touch each other, and although I had a feeling of complete disorientation, a feeling of an inability to do practically anything, I never found a specific thing that I couldn’t do.

  As I said before, the first time in the tank I didn’t get any hallucinations, and the second time I didn’t get any hallucinations. But the Lillys were very interesting people; I enjoyed them very, very much. They often gave me lunch, and so on, and after a while we discussed things on a different level than the early stuff with the lights. I realized that other people had found the sense-deprivation tank somewhat frightening, but to me it was a pretty interesting invention. I wasn’t afraid because I knew what it was: it was just a tank of Epsom salts.

  The third time there was a man visiting—I met many interesting people there—who went by the name Baba Ram Das. He was a fella from Harvard who had gone to India and had written a popular book called Be Here Now. He related how his guru in India told him how to have an “out-of-body experience” (words I had often seen written on the bulletin board): Concentrate on your breath, on how it goes in and out of your nose as you breathe.

  I figured I’d try anything to get a hallucination, and went into the tank. At some stage of the game I suddenly realized that—it’s hard to explain—I’m an inch to one side. In other words, where my breath is going, in and out, in and out, is not centered: My ego is off to one side a little bit, by about an inch.

  I thought: “Now where is the ego located? I know everybody thinks the seat of thinking is in the brain, but how do they know that?” I knew already from reading things that it wasn’t so obvious to people before a lot of p
sychological studies were made. The Greeks thought the seat of thinking was in the liver, for instance. I wondered, “Is it possible that where the ego is located is learned by children looking at people putting their hand to their head when they say, ‘Let me think’? Therefore the idea that the ego is located up there, behind the eyes, might be conventional!” I figured that if I could move my ego an inch to one side, I could move it further. This was the beginning of my hallucinations.

  I tried and after a while I got my ego to go down through my neck into the middle of my chest. When a drop of water came down and hit me on the shoulder, I felt it “up there,” above where “I” was. Every time a drop came I was startled a little bit, and my ego would jump back up through the neck to the usual place. Then I would have to work my way down again. At first it took a lot of work to go down each time, but gradually it got easier. I was able to get myself all the way down to the loins, to one side, but that was about as far as I could go for quite a while.

  It was another time I was in the tank when I decided that if I could move myself to my loins, I should be able to get completely outside of my body. So I was able to “sit to one side.” It’s hard to explain—I’d move my hands and shake the water, and although I couldn’t see them, I knew where they were. But unlike in real life, where the hands are to each side, part way down, they were both to one side! The feeling in my fingers and everything else was exactly the same as normal, only my ego was sitting outside, “observing” all this.

  From then on I had hallucinations almost every time, and was able to move further and further outside of my body. It developed that when I would move my hands I would see them as sort of mechanical things that were going up and down—they weren’t flesh; they were mechanical. But I was still able to feel everything. The feelings would be exactly consistent with the motion, but I also had this feeling of “he is that.” “I” even got out of the room, ultimately, and wandered about, going some distance to locations where things happened that I had seen earlier another day.
