Einstein's Theory of Brownian Motion

Einstein's theory of Brownian motion explains the random movement of tiny particles suspended in a fluid, like pollen in water. This motion occurs because the particles are constantly hit by the much smaller molecules of the fluid, which are moving quickly and chaotically. Einstein's work provided evidence for the existence of atoms and molecules, showing that this seemingly erratic movement has a scientific basis. His findings not only enhanced our understanding of particle behavior but also supported the kinetic theory of matter, which describes how temperature and energy relate to the motion of particles.
