The Feynman Path Integral

The Feynman Path Integral is a way to understand quantum physics by summing all possible ways a particle can move between two points. Instead of a single path, it considers every conceivable route, each with its own probability amplitude. These amplitudes are added together to determine the likelihood of the particle's transition. This approach offers a comprehensive picture of quantum behavior, where particles don't follow definite paths but instead explore all possibilities simultaneously, with the most probable paths dominating the outcome. It's a powerful tool for calculating behaviors in quantum systems.
