Feynman Path Integral

The Feynman Path Integral is a way to understand how particles like electrons move by considering all possible paths they could take from one point to another. Instead of following just a single route, the method sums up contributions from every conceivable path, each with its own probability amplitude. These add together, with some paths reinforcing each other and others cancelling out, resulting in the overall behavior of the particle. This approach provides a powerful framework in quantum physics for predicting how particles behave, emphasizing that their movement is inherently probabilistic and interconnected with all potential trajectories.
