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 schoolbook 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."
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 [Americans] 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.
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 cannot understand. I don't know why, but the books are lousy; UNIVERSALLY LOUSY!
