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

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 cannot understand. I don’t know why, but the books are lousy; UNIVERSALLY LOUSY!

Anyway, I’m happy with this book, because it’s the first example of applying arithmetic to science. I’m a bit unhappy when I read about the stars’ temperatures, but I’m not very unhappy because it’s more or less right—it’s just an example of error. Then comes the list of problems. It says, “John and his father go out to look at the stars. John sees two blue stars and a red star. His father sees a green star, a violet star, and two yellow stars. What is the total temperature of the stars seen by John and his father?”—and I would explode in horror.

My wife would talk about the volcano downstairs. That’s only an example: it was perpetually like that. Perpetual absurdity! There’s no purpose whatsoever in adding the temperature of two stars. Nobody ever does that except, maybe, to then take the average temperature of the stars, but not to find out the total temperature of all the stars! It was awful! All it was was a game to get you to add, and they didn’t understand what they were talking about. It was like reading sentences with a few typographical errors, and then suddenly a whole sentence is written backwards. The mathematics was like that. Just hopeless!

Then I came to my first meeting. The other members had given some kind of ratings to some of the books, and they asked me what my ratings were. My rating was often different from theirs, and they would ask, “Why did you rate that book low?”

I would say the trouble with that book was this and this on page so-and-so—I had my notes.

They discovered that I was kind of a goldmine: I would tell them, in detail, what was good and bad in all the books; I had a reason for every rating.

I would ask them why they had rated this book so high, and they would say, “Let us hear what you thought about such and such a book.” I would never find out why they rated anything the way they did. Instead, they kept asking me what I thought.

We came to a certain book, part of a set of three supplementary books published by the same company, and they asked me what I thought about it.

I said, “The book depository didn’t send me that book, but the other two were nice.”

Someone tried repeating the question: “What do you think about that book?”

“I said they didn’t send me that one, so I don’t have any judgment on it.”

The man from the book depository was there, and he said, “Excuse me; I can explain that. I didn’t send it to you because that book hadn’t been completed yet. There’s a rule that you have to have every entry in by a certain time, and the publisher was a few days late with it. So it was sent to us with just the covers, and it’s blank in between. The company sent a note excusing themselves and hoping they could have their set of three books considered, even though the third one would be late.”

It turned out that the blank book had a rating by some of the other members! They couldn’t believe it was blank, because they had a rating. In fact, the rating for the missing book was a little bit higher than for the two others. The fact that there was nothing in the book had nothing to do with the rating.
