The process of Thomson Joseph John's invention of electronics;
1897 Joseph john thomson of Cavendish Laboratory, Cambridge University, UK, redone Hertz's experiment. Using a vacuum tube with higher vacuum degree and stronger electric field, the deflection of negative rays was observed, and the mass-to-charge ratio of negative ray particles was calculated, so it won the Nobel Prize in Physics of 1906.
Thomson used the name named by George Storni in 189 1 to refer to this particle. At this point, the electron was discovered by Thomson and became the first subatomic particle discovered by human beings, which opened the door to the atomic world.
