WebA cathode made of a wire filament heated red hot by a separate current passing through it would release electrons into the tube by a process called thermionic emission. The first true electronic vacuum tubes, invented in 1904 by John Ambrose Fleming, used this hot cathode technique, and they superseded Crookes tubes.

Cooper pairs can have unique mathematical structures, leading to unconventional superconducting ... WebThe story begins in 1932, with the discovery of the neutron by Sir James Chadwick, an English physicist. Until 1932, the atom was known to consist of a positively charged nucleus surrounded by enough negatively charged electrons to make the atom electrically neutral. Most of the atom was empty space, with its mass concentrated in a tiny nucleus.
