Описание:
He was very interested in atoms from the beginning. He went over to America to give 4 lectures which were pretty interesting. He did an original study of cathode rays which led to the discovery of the electron. Through these studies he was able to find the charge to mass ratio of electrons.Добавлено на ленту времени:
