Hello! This is the twelfth chapter in my series "Maths of Quantum Mechanics." In this episode, we'll take a detour into classical physics to learn about generators in the Lagrangian framework. We'll see that each physical quantity generates a change in the state of our particle, which will be key in deriving the Schrodinger equation next episode. If you have any questions or comments, shoot me an email at: quantumsensechannel@ Thanks! Animations: All animations created by me within Python, using Manim.
