The ghost particle neutrinos is one kind of the elementary particle that called leptons. It carries no charge and almost has no mass and no interaction with any other particles and therefore can freely penetrate the earth. Neutrinos can be created from many different ways, such as the Sun, the atmosphere, the nuclear power plant and the accelerator. Mystery of neutrinos has been fascinating scientists since it is postulated in 1930 by W. Pauli and discovered in 1956 by Reine and Cown, and will continue be so for many decades. This presentation will briefly review the history of the neutrino, the source of neutrino and explain you how scientists solve the puzzle of solar neutrino and the atmospheric neutrino, which were awarded the Nobel prize in physics of 2015.
