Neutrinos and Anti-matter.

... Neutrinos and Anti-matter Neutrinos What are its properties? Neutrinos are one of the fundamental particles, which make up the Universe. They are also one of the least understood. Neutrinos are similar to the more familiar electron but with one crucial difference - neutrinos do not carry electric charge. As neutrinos are electrically neutral, electromagnetic forces do not affect them. Three types of neutrinos are known: there is strong evidence that no additional neutrinos exist. Each type or 'flavor' of neutrino is related to a charged particle. Hence the 'electron neutrino' is associated with the electron, and two other neutrinos are associated with heavier versions of the electron called the 'muon' and the 'tau.' How was it discovered? In the 1930's after James Chadwick's discovery of the neutron, the structure of the atom consisted of protons and neutrons in the nucleus surrounded by a cloud of electrons. Although this was true, in some
