JJ Thomson studied electrical discharges in gases. Following the discovery of x-rays and radioactivity his imaginative work inspired many young researchers, including Ernest Rutherford, WL Bragg and ...

Others thought the rays were streams of particles. J.J. Thomson decided to find out for sure. Thomson was a physics professor at Cambridge University in the UK. He placed cathode tubes in electric ...
