Feynman's Path Integral Principle Directly Confirmed in Lab for First Time

Researchers in China have experimentally verified Richard Feynman's path integral formulation, a cornerstone of quantum mechanics proposed in 1948. By measuring successive propagators of photons through an optical maze, they reconstructed the integral and confirmed its predictions. This marks the first direct experimental validation of the principle, which underpins much of modern particle physics.
