Sir Joseph John Thomson Cheetham 18.12.1856 - Cambridge 30.8.1940 Fisico, noto per i suoi studi sperimentali sull' elettrone , nel 1906 ottenne il premio Nobel per le sue ricerche sulla conducibilità elettrica dei gas. Cinque anni dopo la formulazione della teoria elettronica della materia, Thomson "scopre" l'elettrone. In realtà non si tratta di una vera e propria scoperta, poichè Thomson era già più che convinto circa la validità delle teorie relative ai portatori di carica , ed egli cerca di effettuare delle osservazioni che possano dare valori numerici ai parametri di questi corpuscoli, da lui definiti "atomi elementari"; quindi sarebbe più esatto dire che egli ha dimostrato l'esistenza dell'elettrone. I suoi studi, che sono un connubio fra complesse teorie e altrettanto complessi esperimenti, nel dettaglio dei quali non entriamo, si protraggono per molti anni, e vengono tutti effettuati presso il centro di ricerche sperimentali di Cambridge, intitolato a Lord H.Cavendish, di cui Thomson è divenuto direttore a soli ventotto anni. Le sue ricerche partono dallo studio sui gas rarefatti, nei quali cerca la correlazione fra le leggi dell'elettromagnetismo e la struttura della materia, indagando sui raggi catodici che egli riteneva, contrariamente ai fisici tedeschi, materiali, ed in grado di segnare le traiettorie di particelle di materia, cariche di elettricità negativa.

John Joseph Thomson Discoverer of the Electron Early Life John Joseph Thomson was born on December 18th, 1856 near Manchester. He won a scholarship to Trinity College, Cambridge where he studied Maths and Physics. Here in 1884, he was awarded a fellowship and became Cavendish Professor of Physics and Head of the Cavendish Laboratory . His Father died when he was 16. Discovering the Electron In 1897 Thomson did 3 experiments to prove his theories about Electrons. 1st Experiment Thomson built a cathode ray tube ending in a pair of metal cylinders with a slit in them. These cylinders were in turn connected to an electrometer, a device for catching and measuring electrical charge. He wanted to see if, by bending the rays with a magnet, he could separate the charge from the rays. He found out that you cannot separate the charge from the rays, therefore the negative charge and the cathode rays must somehow be stuck together. 2nd Experiment Thomson thought of a new idea. A charged particle will normally curve as it moves through an electric field, but not if it is surrounded by a conductor e.g. copper. Thomson thought that the traces of gas left in the tube were being turned into an electrical conductor by the cathode rays. To test this idea, he took great pains to extract nearly all of the gas from a tube, and found that now the cathode rays did bend in an electric field. Thomson concluded from these two experiments

J.J. Thomson (1856-1940) Sir 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. He became a Fellow of Trinity College in 1880, when he was Second Wrangler and Second Smith's Prizeman, and he remained a member of the College for the rest of his life, becoming Lecturer in 1883 and Master in 1918. He was Cavendish Professor of Experimental Physics at Cambridge, where he succeeded Lord Rayleigh, from 1884 to 1918 and Honorary Professor of Physics, Cambridge and Royal Institution, London. Thomson's early interest in atomic structure was reflected in his Treatise on the Motion of Vortex Rings which won him the Adams Prize in 1884. His Application of Dynamics to Physics and Chemistry appeared in 1886, and in 1892 he had his Notes on Recent Researches in Electricity and Magnetism published. Thomson co-operated with Professor J. H. Poynting in a four-volume textbook of physics, Properties of Matter and in 1895 he produced Elements of the Mathematical Theory of Electricity and Magnetism, the 5th edition of which appeared in 1921. In 1896, Thomson visited America to give a course of four lectures, which summarised his current researches, at Princeton. These lectures were subsequently published as Discharge of Electricity through Gases (1897). On his return from America, he achieved the most brilliant work of his life - an original study of cathode rays culminating in the discovery of the electron, which was announced during the course of his evening lecture to the Royal Institution on Friday, April 30, 1897. His book, Conduction of Electricity through Gases, published in 1903 was described by Lord Rayleigh as a review of "Thomson's great days at the Cavendish Laboratory". A later edition, written in collaboration with his son, George, appeared in two volumes (1928 and 1933).

This exploration of atomic research demonstrates that the models used to explain the composition of the atom have been refined and improved. Because the concepts of atomic theory are largely abstract, VRML-rendered interactive models are used to present macroscopic representations. Also, students are able to read biographies of relevant scientists. Animated images are used to demonstrate the experiments that were performed and led to the postulation of the particular theory.
