Actually, although all attempts to pin it down in the laboratory have failed, the little neutrino has already made itself useful. When particles are knocked out of a nucleus, there is a mysterious disappearance of both energy of motion and energy of "spin" (angular momentum). It is therefore assumed that the lost energies ride away on the elusive neutrino...
...knocks a neutron and a positron out of an electron, there is a mysterious disappearance of energy. He surmised that the excess energy rode away on a little particle which, now generally accepted as theoretically necessary, still eludes observation. It is because of Fermi that this little particle, the neutrino, has an Italian name...
...space was a system of two identical "sheets" joined here & there by what Dr. Einstein and his associate deemed best to call "bridges." The bridges turned out to be particles. The properties of one bridge identified it as a particle with mass but no electric charge, like the hypothetical neutrino or the familiar neutron. Another bridge indicated the existence of a totally unfamiliar particle, having electric charge but no mass whatever. Particles like protons and electrons, having both mass and charge, seemed to Einstein to represent "two-bridge problems"-two points of space connecting the two space-sheets. The gentle...
...radiation dwindles, would not have to be withdrawn from the body after treatment as radium seeds must be. They told of experiments presaging the production of a radio-phosphorus which would emit neutrons (emitted by no natural radioactive substance). And they spoke of work indicating the existence of the neutrino, an ultimate particle lacking electrical charge like the neutron, but small in mass like the electron. Many a physicist has held the neutrino's existence called for on theoretical grounds, has hesitated to sign its birth certificate because it eludes experimental observation...
