Is ACTION The Most Fundamental Property in Physics?

The video explores the evolution of minimizing principles in physics, starting with Heron of Alexandria's principle of least distance and Fermat's principle of least time. It discusses Newton's laws and LaGrange's principle of least action, which simplifies complex systems by focusing on energy rather than vectors. Hamilton's correction leads to Lagrangian mechanics, which applies to both classical and modern physics, including general relativity and quantum mechanics. The video concludes with Feynman's path integral formulation, showing how these principles unify various physics theories.
