Physicists prove Einstein wrong with observation of instantaneous velocity in Brownian particles
A century after Albert Einstein said we would never be able to observe the instantaneous velocity of tiny particles as they randomly shake and shimmy, so called Brownian motion, physicist Mark Raizen and his ...
