What Yang taught the next generation

1:03:05of Nobel prizes. [laughter] 100% of the attendees of that course, 100% of the attendees of that course won the Nobel Prize. No other course has that, >> you know, cuz he got two students and both won the Nobel Prize. >> So, [laughter] that's actually pretty crazy. >> That's a great like like that's a record that I don't think it's ever going to be beat. >> We're going to put that in the stat locker for FFP when we start the leaderboard. >> Oh, that'll be a great one. Classes. Yeah, >> we're going to build out a stats library just like all major professional sports do for when they when the announcers like, "Oh, this is the Oh, the last time we saw 300 yards, 42 D was it 19 d."

1:03:50>> Yeah, >> we're starting the same stats library. NextGen Stats. >> NextG Stats. And that's going to be that's going to be one that's like never going to be okay. You had two students, both won the Nobel Prize. 100% Nobel Prize winner class. Imagine, right? Um so Sunung Dali is actually um instrumental in the next part of our story >> because Sunung Dali and Yang they are the ones who start looking at that towel theta puzzle that we were talking about right you got these two identical particles they're decaying in weird ways >> the par there there's no conservation of the par uh because they're decaying into

1:04:30two and three which is weird because there's like same size >> same same different. But why are they different? >> Why are they different? >> Like is it is it that they are different or is it that the laws of physics are a bit different? >> Right. Are not cons don't the conservation of parody has exceptions. >> Exactly. Yeah. So so Yang Ching Ning um sorry Yang and Lee they propose a revolutionary idea. What they do is they go back and look at all of the literature. Okay. There's a funny story here where they were in um Colombia at the time and they're searching for parking and they're in the car. He he talks about this in his memoir. They're in the car discussing

1:05:10this issue of the theta and the toao and they're like is par conserved? Like what's going on? And they have this idea but they're looking for parking. They can't find parking because it's Manhattan. There's no parking in Manhattan. Manhattan. So they park in this like restaurant, this Chinese restaurant that hadn't opened yet, but like you know they still the the restaurant had parking. So they find parking, they go into cafe and they continue their their discussion. And what they're really focusing on is has anyone actually checked if beta decay obeys par. There's been all of these experiments to check that electromagnetism obeys this mirror rule.

1:05:51There's been all of these experiments to show that nuclear stuff like the strong nuclear force obeys the mirror symmetry. But has anyone actually done it for the weak nuclear force which is what's involved in beta decay? >> So they decide to go through the literature and they actually find out no. No one has said one way or the other whether beta decay obeys the parody conservation law. >> Mhm. So they write up a paper and they
