Neutrino Physics Now and in the Near Future

Abstract

The current status of neutrino physics is reviewed with some near future perspective. After recollecting the birth of modern neutrino physics with nonzero masses and flavor mixing, I summarize the present status of measurement of the mixing parameters in 2-3, 1-2, and 1-3 sectors of the MNS matrix. Then, I describe the attempts to uncover the regularities, if any, in the measured values of the mixing angles; mostly reviewing. Yet, a possible large deviation of \theta_{23} to the second octant may trigger interests in the triangle relation of the lepton mixing angles. In the latter part of my lecture some perspective of determination of the mass hierarchy and measurement of lepton Kobayashi-Maskawa phase δ\delta are described. Finally, I discuss the prospects of the new, fast developing field of high-energy neutrino astrophysics, and the emerging new precision era of cosmology and particle physics. I conclude with optimistic speculations.
