One of the absolute rules I learned in the war was, don’t know anything you don’t need to know, because if you ever get caught they will get it out of you.
The rule of the game was never assume that anybody, however honorable, would be able to stand up under torture. If Mr. X, who knew where I was, was caught for some reason, I should move.

There is now more economic comment in the supposedly serious literature than survives from the whole of the thousand years commonly denominated as the Middle Ages …
[Heisenberg’s seminal 1925 paper initiating quantum mechanics marked] one of the great jumps-perhaps the greatest-in the development of twentieth century physics.
I knew all the time I was going to get through the war. It was completely irrational, a silly idea, but I was not going to lie down and get myself killed. I was going to get out of it.
Anyone who claims to be familiar with it all is a confessing liar.’ I believe that all physicists would subscribe to the same sentiments regarding their own professional literature. I do at any rate.
