HOME SITE HELP ABOUT SEARCH ... EDUCATIONAL Jean Baptiste Perrin His earliest work was on the nature of cathode rays, and their nature was proved by him to be that of negatively charged particles. He also studied the effect of the action of X-rays on the conductivity of gases. In addition, he worked on fluorescence, the disintegration of radium, and the emission and transmission of sound. The work for which he is best known is the study of colloids and, in particular, the so-called Brownian movement. His results in this field were able to confirm Einstein's theoretical studies in which it was shown that colloidal particles should obey the gas laws, and hence to calculate Avogadro's number N , the number of molecules per grammolecule of a gas. The value thus calculated agreed excellently with other values obtained by entirely different methods in connection with other phenomena, such as that found by him as a result of his study of the sedimentation equilibrium in suspensions containing microscopic gamboge particles of uniform size. In this way the discontinuity of matter was proved by him beyond doubt: an achievement rewarded with the 1926 Nobel Prize. Perrin was the author of many books and scientific papers. His book

From 1910 to 1940 he was professor at the Univ. of Paris, and in 1941 he came to the United States. Perrin specialized in the Brownian movement of particles. For his work on the discontinuous structure of matter and for his discovery of the equilibrium of sedimentation (which permitted an accurate calculation of the size of atoms), he received the 1926 Nobel Prize in Physics. He is noted also for his work on X rays and cathode rays. His works include Atoms (1903, tr. 1923). His son, Francis Henri Perrin, 1901–92, became a director of the French atomic energy commission when it was established in 1946. In 1951, Perrin took over as the organization's high commissioner of atomic energy, following Fr©d©ric Joliot-Curie 's dismissal.

Jean Baptiste Perrin From Wikipedia, the free encyclopedia. Jean Baptiste Perrin , generally known as Jean Perrin September 30 Lille April 17 New York ), was a French physicist In , 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 After Albert Einstein published ( ) his theoretical explanation of Brownian motion in terms of atoms , Perrin did the experimental work to test Einstein's predictions, thereby settling the century-long dispute about John Dalton 's atomic theory Jean Perrin received the Nobel Prize in Physics in for his work on the discontinuous structure of matter, and especially for his discovery of sedimentation equilibrium He was the father of Francis Perrin , also a physicist.

JEAN BAPTISTE PERRIN J ean 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. P errin also carried out research of the interaction between radiation and matter. He also focused on fluorescence and organised education in France. THE CATHODE RAYS
