# Jean Baptiste Perrin

> 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.

## Bio

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. He died on 17 April 1942.
