Oppenheimer Movie Review
David Hess:
Scott Manley just did a 20 minute video about the Trinity test which includes as many details about the design and construction as I have seen in one place:

I wonder if they still use Kryton switches. The datasheet he shows confirms that there are at least two different solid state switch designs with the needed performance.
My father worked at LRL and told me the story about the huge photoflash for reconnaissance planes. I did not know the connection until now. He never told me exactly what he worked on but I figured it out later.
msuffidy:
The movie sort of treated the bomb like oh it really worked. I mean when you think of the progression from discovery of fission to bomb, there has to be some logical steps. Like someone must of thought well if we have a lot of fissions in one place it would do basically the same thing as a chemical explosion, but more powerfully. Maybe someone was messing with bringing a certain amount of material together and had a small tactical kind of explosion and people just thought about how to improve it. There may have been a thrust to it for some reason the Nazis were interested in it. Maybe they were brought to it by extraterrestrials. Saying oh we decided to make it is kind of useless because everyone was going to. The world is more fundamentally out of control than people give credit to.

That someone was Leo Szilard. The film Fat Man and Little Boy started off with him.
TimFox:
When Szilard had his idea about a chain reaction, he filed for a British patent that he assigned to the Admiralty to keep it secret. He was at the University of Chicago during the war.
