There is a wonderful 157 part series of short 3 minute or so videos of a few hours of interviews of Freeman Dyson. Dyson talks about his interactions with the giants in physics and science.
You get a sense of the people who are involved in laying the foundations of physics. Freeman tells you about the nature of the geniuses involved.
Freeman Dyson was a genius. He tells you about the genius of Enrico Fermi. Fermi’s physics intuition and genius saved Freeman Dyson from wasting 5 years working on a physics theory that was wrong. Dyson and a team had already spent many months working on it.
There are interesting insights into high-level math and physics and how to think rigorously at a high level.
Fermi said, When one does a theoretical calculation there are two ways to do it. Either you should have a clear physical model in mind or you should have a rigorous mathematical basis.
Dyson: What do you think of the numerical agreement?
Fermi: How many parameters did you use for the fitting and how many free parameters were there in your method.
Dyson: There are four
Fermi: You know Johnny Von Neumann always used to say with four parameters I could a fit an elephant and with five I could make him wiggle his trunk. I do not find the numerical method very impressive either.
Ten years later quarks were invented. Pions had to be represented as a compound of quarks. All experimental agreement before quarks was illusory.
