Path Integral Quantum Mechanics

Path Integral Quantum Mechanics is a formulation of quantum mechanics that describes the behavior of particles by considering all possible paths they can take between two points. Instead of a single trajectory, it sums over every possible path, weighing each one by a particular probability amplitude. This approach integrates concepts from both quantum physics and classical physics, allowing for the calculation of particle behaviors, interactions, and probabilities. Developed by Richard Feynman, it provides deep insights into the nature of quantum systems and has significant implications for fields like particle physics and quantum field theory.
