Plaque commemorating J. J. Thomson's discovery of the electron outside the old Cavendish Laboratory in Cambridge Autochrome portrait by Georges Chevalier, 1923 Thomson c. 1920–1925 Thomson was elected a Fellow of the Royal Society (FRS) [ 25 ] [ 50 ] and appointed to the Cavendish Professorship of Experimental Physics at the Cavendish ...
[3] [4] [5] Thomas Young's experiment with light was part of classical physics long before the development of quantum mechanics and the concept of wave–particle duality. He believed it demonstrated that the Christiaan Huygens' wave theory of light was correct, and his experiment is sometimes referred to as Young's experiment [6] or Young's ...
Thomson's experiments with cathode rays (1897): J. J. Thomson's cathode ray tube experiments (discovers the electron and its negative charge). Eötvös experiment (1909): Loránd Eötvös publishes the result of the second series of experiments, clearly demonstrating that inertial and gravitational mass are one and the same.

Morley: Negative result Luminiferous aether: 1897 Thomson experiment: J. J. Thomson: Discovery Electron: 1901 Trouton–Noble experiment: Frederick Thomas Trouton and H. R. Noble ...
J. J, Thomson's electric deflection tube, in which he showed that a beam of cathode rays was bent by an electric field like matter particles. The cathode is on R. The electron beam is accelerated passing through the cylindrical high voltage anode ( center ), bent by a voltage on the deflection plates ( center L ), and strikes the back wall of ...
Thomson scattering is a model for the effect of electromagnetic fields on electrons when the field energy is much less than the rest mass of the electron .In the model the electric field of the incident wave accelerates the charged particle, causing it, in turn, to emit radiation at the same frequency as the incident wave, and thus the wave is scattered.
The thought experiment concerns a lamp that is toggled on and off with increasing frequency. Thomson's lamp is a philosophical puzzle based on infinites. It was devised in 1954 by British philosopher James F. Thomson, who used it to analyze the possibility of a supertask, which is the completion of an infinite number of tasks.
