Path Integral Formulation

The Path Integral Formulation, developed by Richard Feynman, represents quantum mechanics through the idea that particles can travel along multiple paths simultaneously. Instead of following a single route, all possible paths contribute to the particle's behavior, with each path assigned a probability amplitude based on its action (a measure of energy and motion). Mathematically, this approach integrates over all these paths, giving a holistic picture of quantum phenomena. In the context of matrix mechanics, it complements other formulations of quantum theory, ultimately offering deep insights into the nature of particles and interactions at the quantum level.
