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 group have done so. "This is the first observation of the instantaneous velocity of a Brownian particle," says Raizen, the Sid W. Richardson Foundation Regents Chair and professor of physics at The University of Texas at Austin. "It's a prediction of Einstein's that has been standing...

Lausanne, Switzerland-- An international group of researchers from the EPFL (Ecole Polytechnique F©d©rale de Lausanne), the University of Texas at Austin and the European Molecular Biology Laboratory in Heidelberg, Germany have demonstrated that Brownian motion of a single particle behaves differently than Einstein postulated one century ago. Their results, to be published online October 11 in Physical Review Letters, provide direct physical evidence that validates a corrected form...

Scientists can now confirm the theory of classical Brownian motion using details that Einstein missed when he first proposed it a century ago 100 years after Einstein's landmark paper, optical tweezer technology could confirm the theory of classical Brownian motion in details that Einstein missed when he first proposed it a century ago. This research is reported today in a special Einstein Year issue of the New Journal of Physics published jointly by the Institute of Physics and the German...
