# Space-Time Approach to Non-Relativistic Quantum Mechanics

@article{Feynman1948SpaceTimeAT, title={Space-Time Approach to Non-Relativistic Quantum Mechanics}, author={Richard Phillips Feynman}, journal={Reviews of Modern Physics}, year={1948}, volume={20}, pages={367-387} }

Non-relativistic quantum mechanics is formulated here in a different way. It is, however, mathematically equivalent to the familiar formulation. In quantum mechanics the probability of an event which can happen in several different ways is the absolute square of a sum of complex contributions, one from each alternative way. The probability that a particle will be found to have a path x(t) lying somewhere within a region of space time is the square of a sum of contributions, one from each path…
