(PhysOrg.com) -- How do thousands of fish swim together in giant schools, seemingly moving as a single body? Flocks of birds, herds of beasts, and a variety of other animals in nature seem to share ...

An important aspect of Brownian motion predicted decades ago has been observed for the first time by researchers in Europe. The team has measured how micrometre-sized spheres interact with a ...

Researchers have for the first time experimentally shown, almost a century later, an idea dating from 1912. In that year the physicist Smoluchowski devised a prototype for an engine at the molecular ...

Brownian motion was one of the many things explained by Einstein. It’s the seemingly random ‘jiggling’ of particles caused by atoms hitting them. Under some circumstances, though, it’s not so random.

The story of Brownian motion began with experimental confusion and philosophical debate, before Einstein, in one of his least well-known contributions to physics, laid the theoretical groundwork for ...
