i am sir joseph john thomson and i am a english physicist
between 1856-1940 i preformed a series of experments ,in 1897 i designed to study the nature of electric dischagein a high-vaccum cathode-ray tube
i used to live in cheetham hill,manchester in england
but i moved away from manchester and moved my life works out to cmabrige, england
I did one of my investigations, back in 1897 conducting the cathode-ray experiment
In 1897 i reported that "cathode rays" were actually negatively charged particles in motion; he argued that the charged particles weighed much less than the lightest atom and were in fact constituents of atoms
later in 1897i discovered the electrons, and found the important of it as a constituent of ordinary matter.
