Neutrino '80 held at the Ettore Majorana Center for Scientific Culture in Erice, was the tenth of a series of International Confer- ences on Neutrino Physics and Astrophysics. It also marked the fiftieth anniversary of the first mention, by Wolfgang Pauli, of a neutral particle emitted in beta decay. The conference occurred at a very propitious time in neutrino physics: the possibility of a non-zero neutrino mass and of neutrino oscillations has obvious implications of great importance in neutrino astrophysics and cosmology, as well as in the grand unified theories. In order to encourage...
