n.
The random movement of microscopic particles suspended in a liquid or gas, caused by collisions with molecules of the surrounding medium. Also called Brownian movement.

[After Robert Brown.]

(ˈbraʊ ni ən)
n.
the random motion of small colloidal particles suspended in a liquid or gas medium, caused by the collision of the medium's molecules with the particles. Also called Brown′ian move′ment.
[1870–75; after Robert Brown (1773–1858), Scottish botanist, who described it in 1827]
