Brownian movement. Small particles suspended in liquid move spontaneously in a random fashion. The motion is caused by unbalanced impacts of molecules on the particle. Brownian motion provided strong circumstantial evidence for the existence of molecules.
Brownian motion or pedesis (from πήδησις /pɛ̌ːdɛːsis/ `leaping`) is the random motion of particles suspended in a fluid (a liquid or a gas) resulting from their collision with the quick atoms or molecules in the gas or liquid. The term `Brownian motion` can also refer to the mathematical model used to describe such random movements...
any of various physical phenomena in which some quantity is constantly undergoing small, random fluctuations. It was named for the Scottish botanist ... [10 related articles]
Three-dimensional, random movement of particles in a gas or liquid.
The continuous random motion of microscopic particles when suspended in a fluid medium. Brownian motion was first observed (1827) by the British botanist Robert Brown (1773-1858) when studying pollen grains in water. The effect was finally explained in 1905 by Albert Einstein, who realized it was ca...
The movement in air of particles of less than 0.1 µm which behave like molecules and move randomly in air.
