Brownian motion moves beyond Einstein's equations

ars reports Brownian motion moves beyond Einstein's equations "There are nuances to particle movement and energy at tiny scales that one of Einstein's equations did not capture, according to a paper published in Science this week. Researchers were able to measure the instantaneous velocity of a tiny glass bead undergoing Brownian motion, or making tiny random movements, and found that the particle was not always governed by the forces that Einstein predicted. Knowing how Brownian motion works at these short intervals may allow researchers to study these tiny particle systems for quantum effects."
