JEAN BAPTISTE PERRIN
Jean Baptiste Perrin,
who lived in the years 1870-1942, was an outstanding French
physicist researching cathode
rays. In 1895 he proved that those rays convey negative charge.
In 1906 his work focused on experimental confirmation of Einstein-Smoluchowski theory
describing Brownian movement. The results constituted a very
powerful proof confirming the atomic theory of the structure of the
world.
Perrin also carried out
research of the interaction between radiation and matter. He also
focused on fluorescence and organised education in France.
