1 gen 1905 anni - John Baptiste Perrin - Proving atoms exist

Descrizione:

John Perrin proved the existence of atoms by first stating that if molecules were real, when particles were blended into a substance, they wouldn't all sink to the bottom. He backed this statement up with an experiment conducted in 1908. He later won a Nobel Prize for his work in 1926.
