Title:  Dancing of the Neutrinos

Abstract: Neutrinos are the most mysterious among the fundamental particles in our universe even though they are the second most abundant. Neutrinos were postulated by Pauli in 1930 and the discovery of neutrinos was finally achieved using reactors by Reines and Cowan  in 1956. We now know that there are three active flavors (or families) of neutrinos (nu_e, nu_mu, nu_tau) and they like to mix while traveling. As a result they can change their flavors like a magic show. This is possible because the neutrinos have mass and even though the masses are very tiny the mass eigenstates are very different than the flavor eigenstates. In this talk I will introduce the neutrinos and related oscillation experiments, and some interesting questions/challenges remained in neutrino physics.
