30 апр 1897 г. - JJ Thompson - Discovering the Electron
Описание:
Thompson was the first person to suggest that one of the fundamental parts of the atom was around 1000 times smaller than an atom. He discovered this while experimenting on the properties of a cathode ray and was able to suggest the existence of the subatomic particle known as an electron.Добавлено на ленту времени:
