He watched dust motes dance in water and proved atoms were real. Perrin's experiments on Brownian motion turned Einstein's equations into observable fact — the kind of work that closes an argument centuries old.

About

Jean Baptiste Perrin was born in France on 30 September 1870. He built his career studying something most scientists had taken for granted: whether matter was truly made of atoms, or if the atomic hypothesis was just a useful fiction. Focusing on Brownian motion — the jittery wandering of tiny particles suspended in liquid — he designed painstaking experiments on sedimentation equilibrium that matched Einstein's theoretical predictions with startling precision. That concordance settled the question: atoms existed, and you could measure their effects. The Nobel Prize in Physics followed in 1926…
