Understand the "brachistochrone problem"—it’s the math behind the physics. Theoretical Mechanics: Theoretical Physics 1

A matrix describing how an object resists rotational motion. Nature takes the path that minimizes the "Action"

Learn how symmetry leads to conservation of momentum, angular momentum, and energy. distances) that suit the geometry

): You can pick any coordinates (angles, distances) that suit the geometry, making complex systems much easier to solve. 3. Symmetry and Noether’s Theorem This is the "soul" of theoretical physics.
