1:25:55gauge theory with with a kind of symmetry breaking, which we don't have to get into, but but he introduced this idea of symmetry breaking. Then we get something like the Higs which comes in to give mass to the W and Z bosons. >> And so all of the standard model starts percolating out of this idea that we can take symmetries of stuff, >> right? >> And and start creating physics >> from those >> from that axiomatic kind of framework. >> We we are we are definitely I have so many thoughts about this. It's >> But are are you starting to see why he's such a big deal in the 20th century? >> No, I I 100% get it because

1:26:35>> it's not the the parody experiment is nice, but this stuff is just like >> whoa. I feel the the other time I felt the same way as this when we was when we talk about the Heisenberg uncertainty principle. It makes me feel the same level of like, >> oh yeah, >> you know what I mean? >> Makes you feel weird in a nice way, but in a weird way, >> right? Like it's it's in from just again for my from my layman's perspective like that's the easiest like category analogy that I can cuz I can much more almost intuitively understand like GR and like where Einstein was coming from. Like that's just for whatever reason easier for me to >> Yeah. He was a sage. That's what I mean.

1:27:16He was a sage. >> That's Yeah. >> Not a magician. >> Not a magician. >> Yeah. [laughter] >> But this this just feels like handwavy and it works. and it works and I but it's just like but like can we go back to >> like wait a minute. >> Yeah. Yeah. And I mean I'm still honestly I'll be honest I'm still kind of there with you on that. Whoa. Right. I still I need to reread this textbook. I need to go through like some quantum field theory textbooks to really try to get what is going on. I in in in my coursework I went all the way up to um you know quantum 3 in my grad graduate school. So we did like elementary quantum field theory. I had I I I know

1:27:57how to derive the DACA equation and things like that. But Yang Mills I'm still sort of wrapping my head around. >> It's it like you the way you've created the journey, >> but that's the that's the way that I've talked about it now is sort of how I've constructed >> right >> the the understanding in my head, >> right? you know, and because I know you so well, I it helps me like you've created a construction that I can engage in at a very very rudimentary level, but you've at least given me the Lego blocks and the building blocks of the framework of like what it is and why it matters. Um, and like why it's this like this inversion of the way to think about

1:28:37things by starting from this like a axiomatic symmetry >> viewpoint argument as like your starting point to then build around. >> Yeah. >> Versus like the other It's just >> my brain. >> Yeah. >> This is Look, for the for those watching, this is what this is. What happens if we only do one story? >> Yeah. >> Yeah. Cuz then cuz then I like really then we just go in. [laughter] And so if you're still listening at this point in the pod, number one, leave a comment so we know. >> Yeah. >> Uh that you you actually like are on the journey with us >> because part of this like I really am trying to grock these concepts and
