I read Feynman lectures on physics Volume 1 Chapter 37 for the 2nd time. It has the best explanation of the 2-slits experiment for me. 1 of the factors behind my <3 for physics is how amazing the universe is. The wave-particle duality is so amazing. I like that Feynman wrote that there was no established idea deeper than quantum mechanics. There’s still no established idea; quantum mechanics is a pillar of physics. I like that he talked a bit re hidden variables. I just wanna add that a hidden-variable idea must be nonlocal.

Chapters 1–36 aren’t prerequisites for Chapter 37. You can read 37 at once.
