What is Brownian motion?

The video explores the random movement of dust particles in light, explaining that this is due to collisions with gas particles. This phenomenon, known as Brownian motion, was first observed by Robert Brown with pollen grains in water. The video challenges viewers to apply this understanding to explain the random motion of pollen grains, summarizing that the effect is due to collisions with water molecules.
