Jean-Pierre Perrin

Jean-Pierre Perrin was a French physicist known for his work on atomic physics and Brownian motion. He conducted pioneering experiments in the early 20th century that helped confirm the existence of atoms, providing important evidence for atomic theory. Perrin's research involved observing tiny particles suspended in liquids, demonstrating how they move randomly—a phenomenon known as Brownian motion. His findings supported atomic models and earned him recognition in the scientific community. Overall, Perrin's work was key in advancing the understanding of matter at the microscopic level.
