2:07untouchables when it comes to sort of physicists who are above reproach in terms of what they've provided over the course of their careers in knowledge and expertise in Nobels in I mean he won the Nobel Prize but and everybody talks about that right um there's a BBC article that came out um on his death and it said you know, Chinese Nobel laurate and physicist Chen Yang dies at the age of 103. That BBC article mostly talks about his Nobel Prize, which was given for um discovering the theoretical foundations for something called parody violation, which is what we're going to get to. But that's not actually why he's considered

2:48one of the greatests, >> okay, >> of the 20th century. I mean, as you said, the 20th century has some of the most influential physicists of all time. Einstein, Boore, Heisenberg. These are the people who not only contributed to our understanding of the modern world but totally reshaped how we think about doing physics in the first place, right? M and Yang is one of those people who completely kind of changed the the way in which we think about trying to do theoretical physics, you know, as theoretical physicists do. And and he came up with the thing that really

3:28immortalized him was this formulation of something called nonabelian gauge theory, which is known as young mil mills theory. >> I remember hearing oh gauge theory, gauge theory all the time. This is the guy who kind of started that whole thing. Okay, Yang Mills theory. And you know in physics circles we we just say Yang Mills theory. It's >> it's a bedrock foundation for the standard model which is one of the most successful um theoretical ideas that we've had as human beings. Okay. And it's rooted in this idea of symmetry. Okay. So in this episode, what I really want to do is go through some of Yang's
