Transition — symmetry as beauty

23:37of a pendulum that is behaving differently because it's on a rotating reference frame. Because it's on a rotating reference frame, the pendulum is going to rotate within itself and knock over those little tiny uh thingies. >> Yes. >> And like show that the Earth is rotating. That was one of the first big, you know, proofs that the Earth is really rotating. And and you're visually kind of showing that there's like this basin, right? Where there's this pendulum that's floating like imagine a clock, but like it's now as it's as the earth rotates, the pendulum will move to different hours on the clock. >> Uh because that reference frame is changing. >> Exactly. >> Uh just in terms for the listeners visually like that's what you're

24:18describing is the rotation makes it so that if the pendulum starts going from 12 to 6, >> as the earth rotates, it's now going from 1 to 7. Yeah. 2 to 8, whatever it might be. >> Yeah. Exactly. And it goes at different it goes at different speeds based on how far up you are on the earth in terms of um latitude, you know. So >> that is not a symmetry, >> right? >> Okay. Like the fact that I can just like I can't just take my experiment and start rotating it at a constant velocity. I can turn it >> and then do stuff. That's that gets me angular momentum, but I can't like constantly be rotating. >> Okay. Okay. So interesting, >> right? So so so these so not everything

24:59is allowed, >> right, >> by the universe. Okay. Certain things are allowed and certain things are not allowed. >> The admin the admin exposed some parameters that are terrible, but it's like not not all of them. >> Not all of it. Yeah. Exactly. And so um in the in in the early 1900s, the question started becoming what are the things that are allowed and what are the things that are not? We've already talked about how uh translation in space is allowed. So I can move my apparatus from here to there. I can move my apparatus in time. So I can do stuff here. I can do stuff tomorrow and it'll be fine. I can rotate it and it'll be fine. What about parody? Okay. The question of the the question is are the

25:39laws of physics ambidextrous? >> Meaning [clears throat] does the law of physics do the laws of
