George Johnstone Stoney (15 February 1826 – 5 July 1911) was an Irish physicist known for introducing the term electron as the "fundamental unit quantity of electricity". [1] He initially named it "electrolion" in 1881, [2] and later named it “electron” in 1891. [3] [4] [5] He published around 75 scientific papers during his lifetime.
The name "electron" was adopted for these particles by the scientific community, mainly due to the advocation by George Francis FitzGerald, Joseph Larmor, and Hendrik Lorentz. [ 37 ] : 273 The term was originally coined by George Johnstone Stoney in 1891 as a tentative name for the basic unit of electrical charge (which had then yet to be ...
The name "electron" was adopted for these particles by the scientific community, mainly due to the advocation by G. F. FitzGerald, J. Larmor, and H. A. Lorentz. [46]: 273 The term was originally coined by George Johnstone Stoney in 1891 as a tentative name for the basic unit of electrical charge (which had then yet to be discovered). [47] [26]
This discovery gave a clue to the subsequently proved intimate relationship between electricity and magnetism which was promptly followed up by Ampère who some months later, in September 1820, presented the first elements of his new theory, which he developed in the following years culminating with the publication in his 1827 "Mémoire sur la ...
Louis Victor Pierre Raymond, 7th Duc de Broglie (/ d ə ˈ b r oʊ ɡ l i /, [1] also US: / d ə b r oʊ ˈ ɡ l iː, d ə ˈ b r ɔɪ /; [2] [3] French: [də bʁɔj] [4] [5] or [də bʁœj] ⓘ; 15 August 1892 – 19 March 1987) [6] was a French theoretical physicist and aristocrat known for his contributions to quantum theory.
The elementary charge, usually denoted by e, is a fundamental physical constant, defined as the electric charge carried by a single proton (+1 e) or, equivalently, the magnitude of the negative electric charge carried by a single electron, which has charge −1 e. [2] [a]
The electron neutrino ( ν e) is an elementary particle which has zero electric charge and a spin of 1 ⁄ 2.Together with the electron, it forms the first generation of leptons, hence the name electron neutrino.
The one-electron universe postulate, proposed by theoretical physicist John Wheeler in a telephone call to Richard Feynman in the spring of 1940, is the hypothesis that all electrons and positrons are actually manifestations of a single entity moving backwards and forwards in time.
