Feynman’s checkerboard (theory)

Feynman's checkerboard theory visualizes how electrons move in space and time like a game of chess. It models an electron's path as a series of straight moves, where at each step it can go forward or switch direction, representing their quantum behavior. Using a grid similar to a checkerboard, this approach sums all possible paths, with each path influencing the electron's overall behavior, including its wave-like properties. This method helps explain particle interactions and quantum probabilities, providing a visual and intuitive way to understand how electrons and other particles behave at the quantum level.
