Robert Brown is best known for his discovery of Brownian motion in 1827. He observed the random, jittery movement of pollen grains suspended in water under a microscope, which provided evidence for the kinetic theory of matter and helped to confirm the existence of atoms and molecules. This phenomenon illustrated the impact of molecular motion on larger particles, significantly advancing the understanding of microscopic processes in physics and chemistry.
