In 1930, the idea of neutrino was born. The neutrino was said to have no mass, no energy attribute (frequency), electrically neutral and not interacting with matter - in short, a physically in-describable entity. In 1956 Clyde L. Cowan and Frederick Reines announced that they had detected the neutrinos released from the nuclear reactor. Since then, the neutrino experiments took a giant leap. All the countries are conducting many neutrino experiments at an enormous cost. Every new neutrino experiment finds new things about neutrinos. The neutrinos have – mass- magnetic moment - left handed property – parallel, anti-parallel – neutrino-antineutrino- flavor – many more. The neutrinos interact with almost all elements such as electron, hydrogen, deuterium, chlorine, gallium. The neutrinos have a complex mechanism by which the neutrinos can change their property (flavor) while travelling. 1n 1900, the gamma rays were discovered. By 1914, all properties of the gamma rays were experimentally found. In 1932, the neutron was discovered. In the subsequent experiments conducted in a couple of years, all the properties of the neutrons were understood. Generally, every new experiment of any physical entity brings closer to the understanding of that physical entity. This is a well-observed fact. In the case of neutrino, every new experiment adds a new property to the neutrino. The mystery of neutrino keeps billowing and deepening. Neutrino experiments grow in size and budget. No useful purpose of neutrino is ever found, excepting sky-high claims of the neutrino scientists to their respective governments for sucking the tax payer’s huge money. All looked little fishy – are the neutrino scientists building castles in the air? This book reviews the neutrino experiments and the findings shock one to the core.
