IN 1905, Albert Einstein published five papers that shook the world of physics. His elegant arguments and conclusions were marvels of physical intuition that addressed dilemmas raised by experimental ...

Research carried out at the University of Pennsylvania has definitively measured and described the Brownian motion of an isolated ellipsoidal particle, completing a path laid out by Einstein 100 years ...

Researchers have been able to increase the diffusion of magnetic whirls, so called skyrmions, by a factor of ten. Researchers of Johannes Gutenberg University Mainz and the University of Konstanz in ...

First observed by botanist Robert Brown in 1827, Brownian Motion describes the continuous, chaotic movement of tiny particles, such as pollen grains, suspended in a medium. This motion results from ...

Time-lapse films of particle motion on the leading lamella of chick heart fibroblasts and mouse peritoneal macrophages were analyzed. The particles were composed of powdered glass or powdered aminated ...

The answer to this question puts a spotlight on two revolutionary 19th-century scientists. In 1828, the Scottish botanist Robert Brown published his observation that tiny particles in suspension were ...

Researchers of Johannes Gutenberg University Mainz and the University of Konstanz in Germany as well as of Tohoku University in Japan have been able to increase the diffusion of magnetic whirls, so ...
