摘要：

Neutrinos are the only known electrically neutral fundamental fermions, and they are arranged to have no mass in the standard model. But flavor oscillations of solar, atmospheric, accelerator and reactor neutrinos imply tiny neutrino masses and significant flavor mixing. In this talk I shall outline what we have known about neutrinos, discuss why they are weakly interacting and extremely light, and conjecture what is probably behind the observed pattern of lepton flavor mixing. Some personal comments on sterile neutrino species and the road ahead will also be given.
