• Mathematicians develop new theory to explain real-world randomness

    03 19, 2020

    Einstein’s theory of Brownian motion, which describes the random movement of particles in fluids, is widely used to model randomness throughout science. However, this revolutionary model only works when a fluid is static, or at equilibrium.

    Now researchers from the University of Tsukuba, Queen Mary University of London, École Polytechnique Fédérale de Lausanne and Imperial College London, have presented a novel theory to explain observed particle movements in these dynamic environments.
