Finally neutrino has mass

The present status of the problem of neutrino mass, mixing and neutrino osc illations is briefly summarized. The evidence for oscillations of atmospher ic neutrinos found recently in the Super-Kamiokande experiment is discussed . Indications in favor of neutrino oscillations obtained in solar neutrino experiments and in the accelerator LSND experiment are also considered. Imp lications of existing neutrino oscillation data for neutrino masses and mix ing are discussed.
