- Second, he explained the jittery dance of microscopic particles - Brownian motion - as the buffets of surrounding atoms.
- The amplitude of the displacements of unattached beads diminishes with a constant slope of - 2, as expected for Brownian motion in a viscous medium (sugar water).
- This does not occur in practice, since random forces such as Brownian motion perturb the cell's trajectory.
Late 19th century: named after Robert Brown (1773–1858), the Scottish botanist who first observed the motion.
