Mathematicians develop new theory to explain real-world randomness
Brownian motion describes the random movement of particles in fluids, however, this revolutionary model only works when a fluid is static, or at equilibrium.

(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 this same “property” ...
In the classic fairy tale, "The Emperor's New Clothes," Hans Christian Andersen uses the eyes of a child to challenge conventional wisdom and help others to see more clearly. In similar fashion, researchers at the University ...

Stirring can allow the dispersion of substances evenly in liquid. Einstein's tea leaf paradox is a concept that shows how tea leaves can concentrate in a doughnut shape through a secondary flow effect during stirring. In ...
(PhysOrg.com) -- "Brownian motion is a very old concept," Klaus Kroy tells PhysOrg.com. "The laws explaining it were formulated more than a century ago by Albert Einstein. However, we are finding some interesting divergences ...
