Perrin, Jean (historical figure)

Perrin, Jean (1870–1943) was a French physicist renowned for his work on Brownian motion. His experiments validated Albert Einstein's theoretical explanation, providing key evidence for the existence of atoms and molecules. Perrin observed tiny particles suspended in liquids moving randomly, and by measuring their motion, he confirmed Einstein’s equations, helping solidify atomic theory in science. His findings earned him the Nobel Prize in Physics in 1926. Perrin's work was crucial in establishing the molecular nature of matter and advancing atomic physics.
