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 (in so-called Brownian motion), physicist Mark ...

An international team of scientists, which included researchers from Nanjing Tech University, used a simple but powerful technique called luminescence spectroscopy to measure the velocities of tiny ...

Researchers in the US have done what Albert Einstein thought was impossible – measure the instantaneous velocity of a particle undergoing Brownian motion. The measurements, performed on micron-sized ...

Einstein said it couldn't be done. But more than one hundred years later physicists at the University of Texas at Austin have finally found a way to witness “Brownian motion”; the instantaneous ...

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 Brownian particle has been measured for the first time, a result Einstein believed would be impossible. By trapping a micron-sized silica bead in air in an optical ...

The seemingly random movement of Brownian motion just got a little more classical. Scientists have been able to image the ultrafast motions of a trapped particle, revealing the underlining ...

A physicist and biogeochemist gets a kick out of the problem of Brownian motion and diffusion. The movement of a particle in a gas or fluid, known as Brownian motion, exhibits two different regimes: ...
