Dwarkesh Patel: evaluation

Transcript context

…We must later on talk about unintended consequences. I find the subject absolutely fascinating. I think my next book might be called Unintended Consequences. You mentioned that a big reason why many of the scientists wanted to work on the bomb, especially the Jewish emigres, was because they're worried about Hitler getting it first. As you mentioned at some point, 1943, 1944, it was becoming obvious that Hitler, the Nazis were not close to the bomb. And I believe that almost none of the scientists quit after they found out that the Nazis weren't close. So why didn’t more of them say — “Oh, I guess we were wrong. The Nazis aren't going to get it. We don't need to be working on it.”? There was only one who did that, Joseph Rotblat. In May of 1945 when he heard that Germany had been defeated, he packed up and left. General Groves, the imperious Army Corps of Engineers General who ran the entire Manhattan Project, was really upset. He was afraid he'd spill the beans. So he threatened to have him arrested and put in jail. But Rotblat was quite determined not to stay any longer. He was not interested in building bombs to aggrandize the national power of the United States of America, which is perfectly understandable. But why was no one else? Let me tell it in terms of Victor Weisskopf. He was an Austrian theoretical physicist, who, like the others, escaped when the Nazis took over Germany and then Austria and ended up at Los Alamos. Weisskopf wrote later — “There we were in Los Alamos in the midst of the darkest part of our science.” They were working on a weapon of mass destruction, that's pretty dark. He said “Before it had almost seemed like a spiritual quest.” And it's really interesting how different physics was considered before and after the Second World War. Before the war, one of the physicists in America named Louis Alvarez told me when he got his PhD in physics at Berkeley in 1937 and went to cocktail parties, people would ask, “What's your degree in?” He would tell them “Chemistry.” I said, “Louis, why?” He said, “because I don't really have to explain what physics was.” That's how little known this kind of science was at that time. There were only about 1,000 physicists in the whole world in 1900. By the mid-30s, there were a lot more, of course. There'd been a lot of nuclear physics and other kinds of physics done by them. But it was still arcane. And they didn't feel as if they were doing anything mean or dirty or warlike at all. They were just doing pure science. Then nuclear fission came along. It was publicized worldwide. People who've been born since after the Second World War don't realize that it was not a secret at first. The news was published first in a German chemistry journal, Die Naturwissenschaften, and then in the British journal Nature and then in American journals. And there were headlines in the New York Times, the Los Angeles Times, the Chicago Tribune, and all over the world. People had been reading about and thinking about how to get energy out of the atomic nucleus for a long time. It was clear there was a lot there. All you had to do was get a piece of radium and see that it glowed in the dark. This chunk of material just sat there, you didn't plug it into a wall. And if you held it in your hand, it would burn you. So where did that energy come from? The physicists realized it all came from the nucleus of the atom, which is a very small part of the whole thing. The nucleus is 1/100,000th the diameter of the whole atom. Someone in England described it as about the size of a fly in a cathedral.…
