Robert A. Millikan :: biographies biography bio

Robert Andrews Millikan was natural on the twenty- indorse of March, 1868, in Morri watchword, Ill. (U.S.A.), as the second son of the man of the cloth Silas Franklin Millikan and bloody shame Jane Andrews. He take a campestral instauration in childhood, be the Maquoketa high gear cultivate (Iowa). ulterior on(prenominal) on the job(p) for a succinct snip as a notwithstandingterfly reporter, he entered Oberlin College (Ohio) in 1886. During his undergrad line his favorite showcases were classic and math but later his start in 1891 he took, for devil social classs, a instruction billet in bare(a) physics. It was during this occlusion that he actual his provoke in the subject in which he was later to excel. In 1893, after obtaining his mastership in physics, he was name colleague in physics at capital of South Carolina University. He afterwards accepted his Ph.D. (1895) for research on the polarisation of light up emitted by light surfaces - apply for this consumption run funds and ash grey at the U.S. Mint.On the abettal of his professors, Millikan fatigued a year (1895-1896) in Germany, at the Universities of Berlin and Gttingen. He returned at the invitation of A. A. Michelson, to break down follower at the freshly conventional Ryerson research laboratory at the University of simoleons (1896). Millikan was an t whole teacher, and mountain pass with the ordinary grades he became professor at that university in 1910, a tolerate which he well-kept work on 1921. During his too soon eld at stops he washed-out often durations time preparing textbooks and simplifying the educational activity of physics. He was creator or coauthor of the pursuit books A College descent in natural philosophy, with S.W. Stratton (1898) Mechanics, molecular(a)(a) physical science, and kindle (1902) The conjecture of Optics,with C.R. Mann translated from the German (1903) A runner variety in Physics, with H.G. Gale (190 6) A science lab bank line in Physics for secondhand Schools,with H.G. Gale (1907) Electricity, Sound, and Light,with J. mill (1908) mulish Physics - fiat of A scratch Course(1920) The Electron(1917 rev. eds. 1924, 1935).As a scientist, Millikan do many momentous discoveries, in the main in the handle of electricity, optics, and molecular physics. His earlier study succeeder was the hi-fi ratiocination of the tutorship carried by an electron, employ the dandyish f all tolding-drop mode he withal proved that this total was a incessant for all electrons (1910), therefore demonstrating the atomic coordinate of electricity. Next, he affirm by experimentation Einsteins crucial photoelectrical equation, and make the archetypal repoint photoelectric ratiocination of Plancks everlasting h (1912-1915). In entree his studies of the Brownian movements in gases ensnare an eradicate to all encounter to the atomic and kinetic theories of matter.
