Did you hear about the old man whose birthday one year lasted only one minute?
It was his sixty-second birthday.
NeutronIn 1932, the “neutron” was described in an article in the journal Nature by its discoverer, James Chadwick, who coined the name for this neutral particle he discovered present in the nucleus of atoms. He was an English physicist who studied at Cambridge, and in Berlin under Geiger, then worked at the Cavendish Laboratory with Ernest Rutherford, where he investigated the structure of the atom. He worked on the scattering of alpha particles and on nuclear disintegration. By bombarding beryllium with alpha particles, Chadwick discovered the neutron for which he received the Nobel Prize for Physics in 1935. He led the UK's work on the atomic bomb in WW II, and was knighted in 1945.« |
