In 1895, he showed that cathode rays were made of corpuscles with negative electric charge. He computed Avogadro's number through several methods. He explained solar energy by the thermonuclear reactions of hydrogen.
Jean Perrin received the Nobel Prize in Physics in 1926 for his work on the discontinuous structure of matter, and especially for his discovery of sedimentation equilibrium.
Jean Baptiste Perrin was born in Lille, September 30, 1870, where he was educated at the École Normal Supérieure, becoming an assistant in physics during 1894-1897, when he began his researches on cathode rays and X-rays.
Perrin was the author of many books and scientific papers.
Perrin was an officer in the engineer corps during the 1914-1918 War.
