Noun
the random motion of small particles suspended in a gas or liquid
Source: WordNetA year later, botanist Robert Brown discovered Brownian motion : pollen grains in water undergoing movement resulting from their bombardment by the fast-moving atoms or molecules in the liquid. Source: Internet
Brownian motion In 1827, botanist Robert Brown used a microscope to look at dust grains floating in water and discovered that they moved about erratically, a phenomenon that became known as " Brownian motion ". Source: Internet
For a realistic particle undergoing Brownian motion in a fluid many of the assumptions cannot be made. Source: Internet
Hence, Lévy's condition can actually be used as an alternative definition of Brownian motion. Source: Internet
However the mathematical Brownian motion is exempt of such inertial effects. Source: Internet
Modeling using differential equations The equations governing Brownian motion relate slightly differently to each of the two definitions of Brownian motion given at the start of this article. Source: Internet
