Stochastic quantum mechanics

Stochastic Quantum Mechanics is a way of looking at the behavior of tiny particles, like electrons and protons. It combines ideas from quantum mechanics (the study of tiny particles) with those from probability (the study of random events). Quantum mechanics tells us that particles have certain properties (like energy and position) but that we can't be sure of exactly what these properties will be. Probability tells us that, even when we can't be sure what will happen, we can often make good guesses by studying probabilities. Stochastic Quantum Mechanics is a way of combining these two things – it helps us make good probabilistic guesses about what particles will do, even when we can't say for sure.
