One of the unsolved mysteries of contemporary science is how highly organized structures can emerge from the random motion of particles. This applies to many situations ranging from astrophysical ...

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 ...

In classical physics, anything driven hard enough will eventually heat up, lose coherence, and settle into disorder. A new ...

Physicists have built a quantum gas that behaves nothing like the substances we are used to, and that is exactly why it is causing such excitement. Instead of slowing down when particles collide, this ...

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 ...

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 ...

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 ...

Metalheads in mosh pits act like atoms in a gas. That’s the conclusion of the first study of the collective motion of people at a rock concert. The finding could add to the realism of ...
