Until then I didn’t let on any of my feelings about the situation to the chairman of the meeting—the big shot who had invited me in the first place. As we were packing our bags to leave, he said to me, all smiles, “You’ll be joining us, then, for the next meeting.”
“No, I won’t.” I could see his face change suddenly. He was very surprised that I would say no, after making those “contributions.”
In the early sixties, a lot of my friends were still giving advice to the government. Meanwhile, I was having no feeling of social responsibility and resisting, as much as possible, offers to go to Washington, which took a certain amount of courage in those times.
I was giving a series of freshman physics lectures at that time, and after one of them, Tom Harvey, who assisted me in putting on the demonstrations, said, “You oughta see what’s happening to mathematics in schoolbooks! My daughter comes home with a lot of crazy stuff!”
I didn’t pay much attention to what he said.
But the next day I got a telephone call from a pretty famous lawyer here in Pasadena, Mr. Norris, who was at that time on the State Board of Education. He asked me if I would serve on the State Curriculum Commission, which had to choose the new schoolbooks for the state of California. You see, the state had a law that all of the schoolbooks used by all of the kids in all of the public schools have to be chosen by the State Board of Education, so they have a committee to look over the books and to give them advice on which books to take.
It happened that a lot of the books were on a new method of teaching arithmetic that they called “new math,” and since usually the only people to look at the books were schoolteachers or administrators in education, they thought it would be a good idea to have somebody who uses mathematics scientifically, who knows what the end product is and what we’re trying to teach it for, to help in the evaluation of the schoolbooks.
I must have had, by this time, a guilty feeling about not cooperating with the government, because I agreed to get on this committee.
Immediately I began getting letters and telephone calls from book publishers. They said things like, “We’re very glad to hear you’re on the committee because we really wanted a scientific guy … and “It’s wonderful to have a scientist on the committee, because our books are scientifically oriented …”
But they also said things like, “We’d like to explain to you what our book is about …” and “We’ll be very glad to help you in any way we can to judge our books …”
That seemed to me kind of crazy. I’m an objective scientist, and it seemed to me that since the only thing the kids in school are going to get is the books (and the teachers get the teacher’s manual, which I would also get), any extra explanation from the company was a distortion. So I didn’t want to speak to any of the publishers and always replied, “You don’t have to explain; I’m sure the books will speak for themselves.”
I represented a certain district, which comprised most of the Los Angeles area except for the city of Los Angeles, which was represented by a very nice lady from the L.A. school system named Mrs. Whitehouse. Mr. Norris suggested that I meet her and find out what the committee did and how it worked.
Mrs. Whitehouse started out telling me about the stuff they were going to talk about in the next meeting (they had already had one meeting; I was appointed late). “They’re going to talk about the counting numbers.” I didn’t know what that was, but it turned out they were what I used to call integers. They had different names for everything, so I had a lot of trouble right from the start.
She told me how the members of the commission normally rated the new schoolbooks. They would get a relatively large number of copies of each book and would give them to various teachers and administrators in their district. Then they would get reports back on what these people thought about the books. Since I didn’t know a lot of teachers or administrators, and since I felt that I could, by reading the books myself, make up my mind as to how they looked to me, I chose to read all the books myself. (There were some people in my district who had expected to look at the books and wanted a chance to give their opinion. Mrs. Whitehouse offered to put their reports in with hers so they would feel better and I wouldn’t have to worry about their complaints. They were satisfied, and I didn’t get much trouble.)
A few days later a guy from the book depository called me up and said, “We’re ready to send you the books, Mr. Feynman; there are three hundred pounds.”
I was overwhelmed.
“It’s all right, Mr. Feynman; we’ll get someone to help you read them.”
I couldn’t figure out how you do that: you either read them or you don’t read them. I had a special bookshelf put in my study downstairs (the books took up seventeen feet), and began reading all the books that were going to be discussed in the next meeting. We were going to start out with the elementary schoolbooks.
It was a pretty big job, and I worked all the time at it down in the basement. My wife says that during this period it was like living over a volcano. It would be quiet for a while, but then all of a sudden, “BLLLLLOOOOOOWWWWW!!!!”—there would be a big explosion from the “volcano” below. The reason was that the books were so lousy. They were false. They were hurried. They would try to be rigorous, but they would use examples (like automobiles in the street for “sets”) which were almost OK, but in which there were always some subtleties. The definitions weren’t accurate. Everything was a little bit ambiguous—they weren’t smart enough to understand what was meant by “rigor.” They were faking it. They were teaching something they didn’t understand, and which was, in fact, useless, at that time, for the child.
I understood what they were trying to do. Many people thought we were behind the Russians after Sputnik, and some mathematicians were asked to give advice on how to teach math by using some of the rather interesting modern concepts of mathematics. The purpose was to enhance mathematics for the children who found it dull.
I’ll give you an example: They would talk about different bases of numbers—five, six, and so on—to show the possibilities. That would be interesting for a kid who could understand base ten—something to entertain his mind. But what they had turned it into, in these books, was that every child had to learn another base! And then the usual horror would come: “Translate these numbers, which are written in base seven, to base five.” Translating from one base to another is an utterly useless thing. If you can do it, maybe it’s entertaining; if you can’t do it, forget it. There’s no point to it.
Anyhow, I’m looking at all these books, all these books, and none of them has said anything about using arithmetic in science. If there are any examples on the use of arithmetic at all (most of the time it’s this abstract new modern nonsense), they are about things like buying stamps.
Finally I come to a book that says, “Mathematics is used in science in many ways. We will give you an example from astronomy, which is the science of stars.” I turn the page, and it says, “Red stars have a temperature of four thousand degrees, yellow stars have a temperature of five thousand degrees …”—so far, so good. It continues: “Green stars have a temperature of seven thousand degrees, blue stars have a temperature of ten thousand degrees, and violet stars have a temperature of … (some big number).” There are no green or violet stars, but the figures for the others are roughly correct. It’s vaguely right—but already, trouble! That’s the way everything was: Everything was written by somebody who didn’t know what the hell he was talking about, so it was a little bit wrong, always! And how we are going to teach well by using books written by people who don’t quite understand what they’re talking about, I ca
