Sir Joseph John Thomson (18 December 1856 – 30 August 1940) was an English physicist who received the Nobel Prize in Physics in 1906 "in recognition of the great merits of his theoretical and experimental investigations on the conduction of electricity by gases."
The Thomson problem is a natural consequence of J. J. Thomson's plum pudding model in the absence of its uniform positive background charge. [ 12 ] "No fact discovered about the atom can be trivial, nor fail to accelerate the progress of physical science, for the greater part of natural philosophy is the outcome of the structure and mechanism ...
The cathode ray tube by which J. J. Thomson demonstrated that cathode rays could be deflected by a magnetic field. The Thomson Medal and Prize is an award which has been made, originally only biennially in even-numbered years, since 2008 by the British Institute of Physics for "distinguished research in atomic (including quantum optics) or molecular physics".
The plum pudding model of J. J. Thomson also had rings of orbiting electrons. The Rutherford paper suggested that the central charge of an atom might be "proportional" to its atomic mass in hydrogen mass units u (roughly 1/2 of it, in Rutherford's model). For gold, this mass number is 197 (not then known to great accuracy) and was therefore ...
J. J. Thomson begins his study of positive rays. 1906 Thomson is awarded the Nobel Prize in Physics "in recognition of the great merits of his theoretical and experimental investigations on the conduction of electricity by gases" 1913 Thomson is able to separate particles of different mass-to-charge ratios.
In the history of physics, a line of force in Michael Faraday's extended sense is synonymous with James Clerk Maxwell's line of induction. [1] According to J.J. Thomson, Faraday usually discusses lines of force as chains of polarized particles in a dielectric, yet sometimes Faraday discusses them as having an existence all their own as in stretching across a vacuum.

Judith Jarvis Thomson (October 4, 1929 – November 20, 2020) was an American philosopher who studied and worked on ethics and metaphysics. Her work ranges across a variety of fields, but she is most known for her work regarding the thought experiment titled the trolley problem and her writings on abortion.
The main pathway for the production of H + 3 is by the reaction of H + 2 and H 2. [18] H + 2 + H 2 → H + 3 + H. The concentration of H + 2 is what limits the rate of this reaction in nature - the only known natural source of it is via ionization of H 2 by a cosmic ray in interstellar space: H 2 + cosmic ray → H + 2 + e − + cosmic ray
