Millikan, Robert Andrews Millikan By courtesy of Caltech, Pasadena, Calif. (b. March 22, 1868, Morrison, Ill., U.S.d. Dec. 19, 1953, San Marino, Calif.), American physicist honoured with the Nobel Prize for Physics in 1923 for his study of the elementary electronic charge and the photoelectric effect. Millikan graduated from Oberlin College (Oberlin, Ohio) in 1891 and obtained his doctorate at Columbia University in 1895. In 1896 he became an assistant at the University of Chicago, where he became a full professor in 1910. In 1909 Millikan began a series of experiments to determine the electric charge carried by a single electron. He began by measuring the course of charged water droplets in an electrical field. The results suggested that the charge on the droplets is a multiple of the elementary electric charge, but the experiment was not accurate enough to be convincing. He obtained more precise results in 1910 with his famous oil-drop experiment , in which he replaced water (which tended to evaporate too quickly) with oil. In 1916 he took up with similar skill the experimental verification of the equation introduced by Albert Einstein in 1905 to describe the photoelectric effect. He used this same research to obtain an exact value of Planck's constant.

Millikan, Robert Andrews Throughout his life Millikan remained a prolific author, making numerous contributions to scientific journals. He was not only a foremost scientist, but his religious and philosophic nature was evident from his lectures on the reconciliation of science and religion, and from his books: Science and Life(1924); Evolution in Science and Religion (1927); Science and the New Civilization (1930); Time, Matter, and Values (1932). Shortly before his death he published Electrons (+ and –), Protons, Photons, Neutrons, Mesotrons, and Cosmic Rays (1947; another rev. ed. of The Electron, previously mentioned,) and his Autobiography(1950). Millikan was an enthusiastic tennis player, and golf was also one of his recreations. Professor Millikan married Greta Erwin Blanchard in 1902; they had three sons: Clark Blanchard, Glenn Allen, and Max Franklin. He died on the 19th of December, 1953, in San Marino, California.

Selected Papers HOME PREFACE AFTERWORD PDF ... GIBBS MILLIKAN COMPTON R OBERT A NDREWS M ILLIKAN During Robert A. Millikan's lifetime at most colleges. At Chicago Millikan began work in various areas such as electrical discharges. But it was as a teacher and textbook writer that Millikan first made his mark. In collaboration he wrote elementary texts that educated a generation of Americans, and in the classroom he proved to be an outstanding educator. These qualities were valued at Chicago, but not as much as research. Millikan was appointed associate professor only at the age of 38, in a time when the median American physicist became a full professor at the age of 32. He later recalled: "Although I had for ten years spent on research every hour I could spare from my other pressing duties, by 1906 I knew that I had not yet published results of outstanding importance, and certainly had not attained a position of much distinction as a research physicist." He thought of devoting himself wholly to education. But instead he stopped writing textbooks and set out on one last try at a new line of research: the determination of the elementary unit of electric charge. His fame was enhanced by continuing scientific work—above all his studies of the phenomenon he named "cosmic rays". He stubbornly insisted that these rays consisted in whole or in large part of electromagnetic radiation, but this error did not prevent him from performing or inspiring much work of basic importance. With his collaborator Ira Bowen he meanwhile opened up the field of vacuum ultraviolet spectroscopy. At the same time he continued his outstanding contributions to education, helping administer Caltech and personally attracting and inspiring a constant stream of students.

To my reply that I did not know any physics at all, his answer was, “Anyone who can do well in my Greek can teach physics.” “All right,” said I, “you will have to take the consequences, but I will try and see what I can do with it.” I at once purchased an Avery’s Elements of Physics , and spent the greater part of my summer vacation of at home … trying to master the subject.

Robert Andrews Millikan Na autobiografia de Robert Millikan, percebe-se como foram inesquecíveis os anos serenos de sua infância em Morrison (lllinois, EUA), onde nasceu em 22 de março de 1868. O convívio com seus irmãos, seu avô camponês e seus pais de mente arejada ensinou-lhe a importante arte de arranjar-se sozinho e a amar a vida simples dos campos. Passou a juventude em Maquoketa (Iowa), onde concluiu seus primeiros estudos. Ingressou depois no Oberlin College, no qual veio a ser suplente no ensino da física. Nessa autobiografia, Millikan sublinha a importância que teve, nas principais resoluções de sua vida, desde o início acidental da carreira, a concatenação de circunstâncias fortuitas. No princípio deste século muitos cientistas dedicaram-se à obra sistemática de medir as constantes naturais mais importantes - a carga do elétron, características espectroscópicas dos átomos, velocidade da luz, etc. - para que o conhecimento do mundo físico constasse, além da teoria, de um bom conjunto de dados e números. Para se ter idéia da importância dessa tarefa, basta dizer que, embora seja entusiasmante a determinação teórica de como se dispõem os elétrons e o núcleo, dentro do átomo, só a comprovação prática através da pesquisa da disposição de todos os elétrons em todos os átomos é que faz a descoberta científica utilizável na prática. Foi nesse setor de trabalho que Millikan retribuiu à sua época as oportunidades e os estímulos que ela lhe proporcionou: com Michelson, na pesquisa física, e Hale, na astronômica, formou o célebre terceto que se destacou nos EUA da época, sobretudo no desenvolvimento de técnicas experimentais.
