The History of Particle Physics

The first subatomic particle the electron was discovered by JJ Thompson in England in 1897. He set out to investigate the nature of these cathode rays by deflection them with electric fields and magnetic fields. From that he managed to establish that those particles were lighter than any atom that had ever been observed before. This then became an incredibly important piece of knowledge which heObviously published and you know wrote all you know many things about because a few years later electrical engineer would sort of pick up this information too.
