Sir Joseph John Thomson OM FRS [1] (18 December 1856 – 30 August 1940) was a British physicist and Nobel Laureate in Physics, credited with the discovery of the electron, the first subatomic particle to be found.
Jun 7, 2024 · J.J. Thomson, English physicist who helped revolutionize the knowledge of atomic structure by his discovery of the electron (1897). He received the Nobel Prize for Physics in 1906 and was knighted two years later.
Joseph John Thomson was born in Cheetham Hill, a suburb of Manchester on December 18, 1856. He enrolled at Owens College, Manchester, in 1870, and in 1876 entered Trinity College, Cambridge as a minor scholar.
J. J. Thomson autobiography. Joseph John Thomson was born on December 18, 1856 in Cheetham, a suburb of Manchester. His father was a bookseller and publisher. It was originally intended that he should be an engineer, and, at the age of fourteen, he was sent to Owens College - later Manchester University - until there was a vacancy for an ...
Key points. J.J. Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Thomson's plum pudding model of the atom had negatively-charged electrons embedded within a positively-charged "soup."
Joseph John Thomson. The Nobel Prize in Physics 1906. Born: 18 December 1856, Cheetham Hill, United Kingdom. Died: 30 August 1940, Cambridge, United Kingdom. Affiliation at the time of the award: University of Cambridge, Cambridge, United Kingdom.
Feb 2, 2020 · These experiments led to the development of the mass spectrograph. Thomson was closely aligned with chemists of the time. His atomic theory helped explain atomic bonding and the structure of molecules. Thomson published an important monograph in 1913 urging the use of the mass spectrograph in chemical analysis.
Along with the nearly contemporaneous discoveries of radioactivity and x rays, the discovery of the electron focused the attention of scientists on the problem of atomic structure, as well as on ways to put these invisible phenomena to use with inventions such as radio and television.
Sir J. J. Thomson, (born Dec. 18, 1856, Cheetham Hill, near Manchester, Eng.—died Aug. 30, 1940, Cambridge, Cambridgeshire), English physicist. Educated at the University of Cambridge, he taught there at the Cavendish Laboratory (1884–1918), which he developed into a world-renowned institution, and was master of Trinity College (1918–40).
An exhibit by the AIP Center for History of Physics with text, animations and voice about J.J. Thomson's 1897 experiments which helped bring understanding of the electron as a fundamental unit of matter.
