The quark model organizes particles by treating protons and neutrons as objects with internal constituents. The discussion connects Murray Gell-Mann’s Eightfold Way to the use of symmetry to make sense of the growing particle zoo.

13:46these discoveries. The eightfold way and the quark model. Yes. Um this is kind of a cute name, the eight-fold way. Moray Gellman at the California Institute of Technology, Caltech in Pasadena. He was um worried about why protons and neutrons have the same mass but way different charge. Seems like there's something inside, right? Seems like there might be some constituents that together make up the same mass, but because of their identity create the different charge. The proton having a positive charge, the neutron having a neutral charge. He figured out the eight-fold way and he introduced this quark model and he organized the
14:26particle zoo using SU3 symmetry which is a type of rotational symmetry has to go back to Yang Mills and things like that. >> Um and he earned the 1969 Nobel Prize in physics. I want to do a deep dive on just Murray Galman and his beef with Richard Fineman because they were both at Caltech Physics and they both hated each other and I think Murray Galman for good reason. Like there's stories of like Fineman making fun of Galman for washing his hands after using the bathroom and he's like, "Oh, you're just one of those, you know, you know those non-thinker types, >> the woke non-thinkers." >> Yeah. Yeah. You're you're one of you're just one of those, you know, the NPC is
15:09effectively what he said. Like you don't think for yourself. It's like, dude, I'm just washing my hands >> after I pee. Anyways, it's it's quite hilarious. Murray Galman, Caltech won the Nobel Prize in 1969. >> We do like to talk about first principles and sometimes that interacts with academic beef, which we both have
