Theoretical neutrino physics

I review the interpretation of the recent beautiful neutrino oscillation data, in particular the major breakthrough in the solar neutrino problem. Then I list the Seven Questions in neutrino physics and how we may address them in the future. In the end I try to put the neutrino masses and mixings in the context of the question of flavor, and conclude. PACS: 14.60.Pq Neutrino mass and mixin
