DEF

The irregular motion of a body arising from the thermal motion of the molecules of the material in which the body is immersed.

CONT

The suspended particle follows a current in the liquid ..., various phenomena cause its path to change and bring it into contact with the material [as] direct interception, diffusion by Brownian motion, ... gyrational movement under the action of hydrodynamic forces ...

OBS

Brownian motion may be thought of as the limiting case of a random walk as the step length tends to zero. The process is statistically self-similar.

DEF

Mouvement désordonné continu des particules microscopiques en suspension dans un liquide ou un gaz.

OBS

À une échelle plus macroscopique, la turbulence de l’air se révèle de façon analogue, par les trajectoires erratiques, aléatoires des feuilles mortes, dues à l’influence combinée d’une multitude de facteurs. Les simulations de mouvements browniens peuvent être linéaires, planaires, bidimensionnelles, fractionnaires, tridimensionnelles ou quadridimensionnelles.

PHR

Le mouvement brownien apparaît, disparaît, se manifeste par l’errance, s’organise, se superpose.
