Feynman's path integral

Feynman's path integral describes how particles, like electrons, move by considering all possible paths they could take between two points. Instead of a single route, the particle "explores" every trajectory, each weighted by a number called an amplitude, which influences the likelihood of that path. When all these contributions are summed, the result predicts the particle's behavior. This approach provides a powerful way to understand quantum mechanics, emphasizing that particles don't have a single, definite path, but rather a superposition of many, all contributing to what we observe.
