Feynman was a truly great teacher. He prided himself on being able to devise ways to explain even the most profound ideas to beginning students. Once, I said to him, "Dick, explain to me, so that I can understand it, why spin one-half particles obey Fermi-Dirac statistics." Sizing up his audience perfectly, Feynman said, ''I'll prepare a freshman lecture on it." But he came back a few days later to say, "I couldn't do it. I couldn't reduce it to the freshman level. That means we don't really understand it."

In 1964 the eminent physicist Richard Feynman served on the State of California's Curriculum Commission and saw how the Commission chose math textbooks for use in California's public schools. In his acerbic memoir of that experience, titled "Judging Books by Their Covers," Feynman analyzed the Commission's idiotic method of evaluating books, and he described some of the tactics employed by schoolbook salesmen who wanted the Commission to adopt their shoddy products. "Judging Books by Their Covers" appeared as a chapter in "Surely You're Joking, Mr. Feynman!" -- Feynman's autobiographical book that was published in 1985 by W.W. Norton & Company.


I was giving a series of freshman physics lectures [in 1964], 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!"

"Ik wilde heel graag vijf zijn, want als je vijf bent, dan wordt je sneller zes. Want het allerleukste lijkt mij acht jaar te zijn. Dat is even oud als mijn broer Jaydie nu. Ik hoop zijn tweelingbroer te kunnen worden. Maar vijf is ook leuk, want nu mag ik op zwemles."

There are four laws [in thermodynamics]. The third of them, the Second Law, was recognized first; the first, the Zeroth Law, was formulated last; the First Law, was second; the Third Law might not even be a law in the same sense as the others.

I was sitting next to a young girl who didn't know her scheme very well.

"Where does 2900 Roteford go?" she asked me.

"Try throwing it to 33," I told her.

The supervisor was talking to her.

"You say you're from Kansas City? Both my parents were born in Kansas City."

"Is that so?" said the girl.

Then she asked me:

"How about 8400 Meyers?"

"Give it to 18."

She was a little on the plump side but she was ready. I passed. I'd had it with the ladies for a while. The supervisor was standing real close to her.
