WebJan 1, 2024 · Equation 8: The classical path is obtained by extremizing this action. This is called the Hamilton principle.. Feynman’s Space-Time Approach. As we just saw, while in classical physics a particle motion has a definite path, in quantum mechanics all possible paths must be taken into account.

WebPhysicist Richard Feynman once said, “The first principle is that you must not fool yourself, and you are the easiest person to fool.” One way we fool ourselves is by imagining we know more than we do; we think we are experts.

The argument for this is made, in a lively manner, in one of the famous Feynman lectures [2]. A key part of the argument is that the Principle of Least Action is not just a technique for obtaining classical equations of motion of particles ... toutatice lycee savina
