Robert Brown (professor)

Robert Brown was a Scottish botanist in the 19th century renowned for discovering what is now called "Brownian motion." This refers to the random, jittery movement of tiny particles suspended in a fluid, caused by collisions with the much smaller molecules of the fluid. His observations provided crucial evidence for the existence of atoms and molecules, advancing the understanding of particle dynamics and atomic theory. Brown's work helped lay the foundation for modern statistical physics and contributed significantly to the development of physical chemistry and the study of microscopic phenomena.
