If you have 70 spare minutes and you are interested in the Manhattan Project or if you want some cool physics-based entertainment, watch (listen to) this:
On Thursday, February 6, 1975, Richard Feynman gave this talk in Santa Barbara.
The talk is pretty interesting, starting from the introduction involving some special and sophisticated praises of Feynman as a physicist (and drummer).
Feynman also unmasks lots about the sociology of the work over there, the relationship between men of different ranks, and so on. (Feynman hadn't completed his thesis yet.) On a committee, Compton would say something that was right. And tons of others said things and fog that didn't really agree or was alternative. But they remembered it and at the end, they approved the conclusion that Compton's point was the best one, anyway. ;-)
In the movies, guys like Feynman who would be giving lectures about the energy yield etc. would wear suits. Feynman would have a dirty shirt. The real world is often nicer than movies.
When they were moving to the place, they were warned that they had to buy train tickets from Princeton to Albuquerque through different places because it would be too visible for so many people to go from one small train station to a particular faraway distant town. People would figure out something was going on. So everyone bought tickets to random places except for Feynman who figured out that everyone would be choosing different places, so he could pick Princeton, NJ. ;-) However, the railway employees told him: "I see, so all this stuff is for you!" :-)
He talks about the landscape, the teams, the tricks to do the numerical calculation quickly in their heads. Feynman also mentions his simple trick to avoid having a roommate. He became a local representative because of some funny thing. The rules of censorship were delicately arranged – the censorship was "voluntary" – but Feynman and his wife found a trick to justify their encrypted letters. ;-)
Feynman couldn't mention the censorship but his wife was doing so. Feynman was ordered to tell his wife to avoid the word "censorship" but the letter where he asked her was censored, of course. He mentions some pranks done on Teller. But there is not too much space for fun because the time between the moment when Teller sees something is wrong and the moment when he knows exactly what happened is too short. :-)
He knew virtually everything about the research and bombs etc. so due to his rarity among the generals, he was treated as the ultimate genius. Which he was, sort of. But there are the funny things about how he wasn't able to read the maps. It was too late to ask what the sign meant. What happens when this valve gets stuck? He took the risk that it was not a valve. After some exchange, they would scream: You're absolutely right! :-)
The disease of playing with computer models is discussed, too. Tricks of his team to do the old-computer-assisted calculations quickly enough. His wife died. The test had to be done. Feynman rejected the glasses – the only guy who actually saw the first test. The sound came some time after the flash. William Laurence, a journalist sent by The New York Times to write about the event, would ask "what was that?" That was the bomb! ;-) Feynman has described his pedagogic patience with folks like the journalist moron in some detail.
Comments about post-Manhattan frustration when he returned to the civilization. He was thinking how large a territory around Cornell would be smashed by a bomb, and so on. The world look over for a while. Why do the people keep on building new bridges? Fortunately, they were right for 30 (now 70) years.
