During the Middle Ages there were all kinds of crazy ideas, such as that a piece of rhinoceros horn would increase potency. Then a method was discovered for separating the ideas which was to try one to see if it worked, and if it didn't work, to eliminate it. This method became organized, of course, into science. And it developed very well, so that we are now in the scientific age. It is such a scientific age, in fact, that we have difficulty in understanding how witch doctors could ever have existed, when nothing that they proposed ever really worked or very little of it did.
But even today I meet lots of people who sooner or later get me into a conversation about UFOs, or astrology, or some form of mysticism, expanded consciousness, new types of awareness, ESP, and so forth. And I've concluded that it's not a scientific world.

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!"

Found Out in Paris
I gave a series of lectures in physics that the AddisonWesley Company made into a book, and one time at lunch we were discussing what the cover of the book should look like. I thought that since the lectures were a combination of the real world and mathematics, it would be a good idea to have a picture of a drum, and on top of it some mathematical diagrams circles and lines for the nodes of the oscillating drumheads, which were discussed in the book.
The book came out with a plain, red cover, but for some reason, in the preface, there's a picture of me playing a drum. I think they put it in there to satisfy this idea they got that "the author wants a drum somewhere." Anyway, everybody wonders why that picture of me playing drums is in the preface of the Feynman Lectures, because it doesn't have any diagrams on it, or any other things which would make it clear. (It's true that I like drumming, but that's another story.)

Bringing Culture to the Physicists
Nina Byers, a professor at UCLA, became in charge of the physics colloquium sometime in the early seventies. The colloquia are normally a place where physicists from other universities come and talk pure technical stuff. But partly as a result of the atmosphere of that particular period of time, she got the idea that the physicists needed more culture, so she thought she would arrange something along those lines: Since Los Angeles is near Mexico, she would have a colloquium on the mathematics and astronomy of the Mayans the old civilization of Mexico.
(Remember my attitude to culture: This kind of thing would have driven me crazy if it were in my university!)

Alfred Nobel's Other Mistake
In Canada they have a big association of physics students. They have meetings; they give papers, and so on. One time the Vancouver chapter wanted to have me come and talk to them. The girl in charge of it arranged with my secretary to fly all the way to Los Angeles without telling me. She just walked into my office. She was really cute, a beautiful blonde. (That helped; it's not supposed to, but it did.) And I was impressed that the students in Vancouver had financed the whole thing. They treated me so nicely in Vancouver that now I know the secret of how to really be entertained and give talks: Wait for the students to ask you.
Judging Books by Their Covers
After the war, physicists were often asked to go to Washington and give advice to various sections of the government, especially the military. What happened, I suppose, is that since the scientists had made these bombs that were so important, the military felt we were useful for something.
Once I was asked to serve on a committee which was to evaluate various weapons for the army, and I wrote a letter back which explained that I was only a theoretical physicist, and I didn't know anything about weapons for the army.

Is Electricity Fire?
In the early fifties I suffered temporarily from a disease of middle age: I used to give philosophical talks about science how science satisfies curiosity, how it gives you a new world view, how it gives man the ability to do things, how it gives him power and the question is, in view of the recent development of the atomic bomb, is it a good idea to give man that much power? I also thought about the relation of science and religion, and it was about this time when I was invited to a conference in New York that was going to discuss "the ethics of equality."
There had already been a conference among the older people, somewhere on Long Island, and this year they decided to have some younger people come in and discuss the position papers they had worked out in the other conference.

But Is It Art?
Once I was at a party playing bongos, and I got going pretty well. One of the guys was particularly inspired by the drumming. He went into the bathroom, took off his shirt, smeared shaving cream in funny designs all over his chest, and came out dancing wildly, with cherries hanging from his ears. Naturally, this crazy nut and I became good friends right away. His name is Jerry Zorthian; he's an artist.
We often had long discussions about art and science. I'd say things like, "Artists are lost: they don't have any subject! They used to have the religious subjects, but they lost their religion and now they haven't got anything. They don't understand the technical world they live in; they don't know anything about the beauty of the real world the scientific world so they don't have anything in their hearts to paint."

It Sounds Greek to Me!
I don't know why, but I'm always very careless, when I go on a trip, about the address or telephone number or anything of the people who invited me. I figure I'll be met, or somebody else will know where we're going; it'll get straightened out somehow. One time, in 1957, I went to a gravity conference at the University of North Carolina. I was supposed to be an expert in a different field who looks at gravity. I landed at the airport a day late for the conference (I couldn't make it the first day), and I went out to where the taxis were. I said to the dispatcher, "I'd like to go to the University of North Carolina."
Thirteen Times
One time a science teacher from the local city college came around and asked me if I'd give a talk there. He offered me fifty dollars, but I told him I wasn't worried about the money. "That's the city college, right?"
"Yes."
I thought about how much paperwork I usually had to get involved with when I deal with the government, so I laughed and said, "I'll be glad to give the talk. There's only one condition on the whole thing" I pulled a number out of a hat and continued "that I don't have to sign my name more than thirteen times, and that includes the check!"

The 7 Percent Solution
The problem was to find the right laws of beta decay. There appeared to be two particles, which were called a tau and a theta. They seemed to have almost exactly the same mass, but one disintegrated into two pions, and the other into three pions. Not only did they seem to have the same mass, but they also had the same lifetime, which is a funny coincidence. So everybody was concerned about this.
At a meeting I went to, it was reported that when these two particles were produced in a cyclotron at different angles and different energies, they were always produced in the same proportions so many taus compared to so many thetas.

Would You Solve the Dirac Equation?
Near the end of the year I was in Brazil I received a letter from Professor Wheeler which said that there was going to be an international meeting of theoretical physicists in Japan, and might I like to go? Japan had some famous physicists before the war Professor Yukawa, with a Nobel prize, Tomonaga, and Nishina but this was the first sign of Japan coming back to life after the war, and we all thought we ought to go and help them along.
Wheeler enclosed an army phrasebook and wrote that it would be nice if we would all learn a little Japanese. I found a Japanese woman in Brazil to help me with the pronunciation, I practiced lifting little pieces of paper with chopsticks, and I read a lot about Japan. At that time, Japan was very mysterious to me, and I thought it would be interesting to go to such a strange and wonderful country, so I worked very hard.
