Tau (particle) Another one is an onium atom called "true tauonium" and is difficult to detect due to tau's extremely short lifetime at low (non-relativistic) energies needed to form this atom. Its detection is important for quantum electrodynamics. Tau (particle) The tau (τ), also called the tau lepton, tau particle, or tauon, is an elementary particle similar to the electron, with negative electric charge and a spin of. Together with the electron, the muon, and the three neutrinos, it is a lepton. Like all elementary particles with half-integer spin, the tau has a corresponding antiparticle of opposite charge but equal mass and
George (given name) George (given name) George is a widespread masculine given name, derived from the Greek () through the Latin . Its popularity is due to the widespread veneration of the Christian military saint Saint George (George of Lydda, d. 303). The Greek name as given in the Roman era may ultimately derive from the name of Zeus Georgos, an epithet of Zeus in his aspect as the god of crops. Even though the saint has been considered a patron saint of England since the 15th or 16th century, the given name was rarely given in English prior to the accession of
