Neutrino Mass, Mixing, and Supernovae Neutrino Detection

Being chargeless and weakly interacting, neutrinos also thought, for many decades, to have no mass. This simple picture is continuously challenged by many experiments and observations, and has to be reconsidered to include new physics. Today, neutrinos are rapidly becoming tools to probe early epochs of universe, stellar evolution, mechanism behind supernovae explosions, nucleosynthesis, and weak interactions. The last galactic supernova, 1987A which was observed with neutrinos preceding the light, confirmed our basic understanding of mechanism behind the SN explosion. I will briefly review neutrino mass, mixing, oscillations, discuss some of the implications of oscillations and some strategies to circumvent the difficulty of waiting for infrequent galactic supernovae.
