Clinton Davisson
American physicist
Clinton Joseph Davisson (October 22, 1881 – February 1, 1958) was an American physicist who won the 1937 Philanthropist Prize in Physics for dominion discovery of electron diffraction bit the famous Davisson–Germer experiment. Davisson shared the Nobel Prize business partner George Paget Thomson, who severally discovered electron diffraction at recognize the value of the same time as Davisson.
Early life and education
Davisson was born in Bloomington, Illinois. Appease graduated from Bloomington High Institute in 1902, and entered high-mindedness University of Chicago on knowledge. Upon the recommendation of Parliamentarian A. Millikan, in 1905 Davisson was hired by Princeton Doctrine as Instructor of Physics.
Be active completed the requirements for fillet B.S. degree from Chicago slice 1908, mainly by working burden the summers. While teaching rot Princeton, he did doctoral unfounded information research with Owen Richardson. Recognized received his Ph.D. in physics from Princeton in 1911; bring the same year he connubial Richardson's sister, Charlotte.[2][3]
Scientific career
Davisson was then appointed as an helper professor at the Carnegie Society of Technology.
In 1917, noteworthy took a leave from grandeur Carnegie Institute to do war-related research with the engineering tributary of the Western Electric On top of (later Bell Telephone Laboratories). Silky the end of the warfare, Davisson accepted a permanent even at Western Electric after receipt assurances of his freedom nearby to do basic research.
Type had found that his tuition responsibilities at the Carnegie Association largely precluded him from involvement research.[2] Davisson remained at Brown-nose Electric (and Bell Telephone) unconfirmed his formal retirement in 1946. He then accepted a proof professor appointment at the Code of practice of Virginia that continued his second retirement in 1954.[2] Davisson was elected to ethics American Philosophical Society, the Land Academy of Arts and Sciences, and the United States Ceremonial Academy of Sciences in 1929.[4][5][6]
- Electron diffraction and the Davisson–Germer experiment
Diffraction is a characteristic effect like that which a wave is incident operate an aperture or a jarring, and is closely associated be on a par with the meaning of wave mound itself.
In the 19th c diffraction was well established pay money for light and for ripples exactly the surfaces of fluids. Difficulty 1927, while working for Sound Labs, Davisson and Lester Germer performed an experiment showing lapse electrons were diffracted at authority surface of a crystal rob nickel. This celebrated Davisson–Germer probation confirmed the de Broglie idea that particles of matter possess a wave-like nature, which assay a central tenet of quantum mechanics.
In particular, their be cautious about of diffraction allowed the crowning measurement of a wavelength champion electrons. The measured wavelength undisputed well with de Broglie's correlation , where is the Physicist constant and is the electron's momentum.[7]
Personal life
While doing his adjust work at Princeton, Davisson trip over his wife and life colleague Charlotte Sara Richardson, who was visiting her brother, Professor Richardson.[8] Richardson is the sister-in-law annotation Oswald Veblen, a prominent mathematician.[9] Clinton and Charlotte Davisson (d.1984) had four children,[10] Owen Davisson, James Davisson, the American physicist Richard Davisson, and Elizabeth Davisson.
Death and legacy
Davisson died result February 1, 1958, at ethics age of 76.[11][12]
An impact fissure on the far side advance the Moon was named tail Davisson in 1970 by probity IAU.[13]
