This volume is a collection of the scientific papers of Frederick Reines. Its publication is to commemorate the 70th birthday, in 1988, of this distinguished scientist. The selected papers here cover many aspects of his work in neutrino physics, astrophysics and conservation law tests. They have been divided into logical groupings, each introduced by a leading authority in that field, who helps the reader to see the reprinted articles with a better historical and scientific perspective.Contents:VitaIntroductionSelected BiblographySelected Papers: Effects of Nuclear ExplosionsDiscovery of the NeutrinoNeutrino PropertiesNeutrino-Electron Elastic ScatteringDeuterium ExperimentsCosmic Rays and Atmospheric NeutrinosSolar NeutrinosExtra-solar NeutrinosGamma-Ray AstronomyBaryon ConservationOther Conservation LawsDouble-Beta DecayNuclear PhysicsExperimental TechniquesTeaching of PhysicsHistorical and Review PapersReadership: High energy physicists and astrophysicists.Key Features:All contributors are women mathematicians, amongst whom many are world leaders in their fieldsContains excellent graduate-level survey articles on symplectic topology, graph theory, number theory, etc.Contains interesting extra material on women in mathematics
