Brownian motion [brou′nyən] Etymology: Robert Brown, Scottish botanist, 1773-1858 a random movement of microscopic particles suspended in a liquid or gas, such as the continuing erratic behavior of dust particles in still water. The movement is produced by the natural kinetic activity of molecules of the fluid that strike the foreign particles. Also called Brownian movement. How to thank TFD for its existence?

A dancer who brought a kinetic zest to every role, she has always had an affinity with Brownian motion. The phenomenon that would eventually become known as Brownian motion defied some of Newton's deterministic laws of matter. The laser channel does not assume sphericity and is not subject to effects of optical and physical properties of particles or medium (such as refractive indices, absorption, surface texture, porosity, electrical conductivity, viscosity variations, Brownian motion or thermal convection). |
