Perrin (scientist)

Jean Perrin was a French physicist known for his work on the kinetic theory of gases and his experiments that provided strong evidence for the existence of atoms. In the early 20th century, he conducted groundbreaking experiments using Brownian motion, where tiny particles suspended in a fluid move unpredictably due to collisions with molecules. His findings helped to confirm the atomic theory proposed by scientists like Dalton and Einstein. In 1926, Perrin was awarded the Nobel Prize in Physics for his contributions, which significantly advanced our understanding of atomic and molecular behavior.
