State Feynman's central postulate of the path integral formulation.1 / 6

The quantum amplitude for a particle to go from point A to point B is a sum over every possible path connecting them, each path weighted by e^(iS[path]/ℏ), where S is the classical action of that path. Unlike classical mechanics, which picks out one extremal path, quantum mechanics sums the contributions of literally all paths, however wild.
