Quantum Invariance & The Origin of The Standard Model

Season 4 Episode 31

Our laws of physics are equations of motion, along with some associated constants. We’ve talked about the symmetries of these equations, and how they lead us to conserved quantities. But this is just the tip of the theoretical iceberg - sometimes investigating the symmetries of these equations predicts entirely new physics. The standard model of particle physics is a remarkable example.
