WebBrownian motion is in the rst place a natural phenomenon, observed by the Scottish botanist Robert Brown in 1827. It consists of the tiny but endless and random motion of small particles, contained in pollen grains, at the surface of a liquid. It naturally interested botanists until Brown and some physicists brought it into the eld of physics. Web2 mrt. 2024 · Brownian motion is the perpetual irregular motion exhibited by small particles immersed in a fluid.
