1 gen 1915 anni - Eugen Goldstein

Descrizione:

German physicist
He was an early investigator of discharge tubes
the discoverer of anode rays
sometimes credited with the discovery of the proton.
He discovered positive particles and noted that the particles had a charge equal and opposite to the electron
He determined that the mass of the proton is 1,840 times heavier than an electron.
In his experiment, he used cathode rays and at the same time discovered canal rays. When Goldstein sent the Cathode rays through the Cathode ray, which are full of electrons, he observed that there were rays going in the opposite direction. Those were the Canal rays. He assumed that these new rays had the equal and opposite charge of the electron.
