- 1. the nineteenth letter of the Greek alphabet (Τ, τ), transliterated as ‘t.’.
Fundamentals. Definition. τ is commonly defined as the ratio of a circle 's circumference c to its radius r : Approximate value. Tau is often written as τ. It is also an irrational number, meaning it cannot be written as a fraction ( ), where 'a' and 'b' are integers (whole numbers).
The tau ( τ ), also called the tau lepton, tau particle, tauon or tau electron, is an elementary particle similar to the electron, with negative electric charge and a spin of 1 2. Like the electron, the muon, and the three neutrinos, the tau is a lepton, and like all elementary particles with half-integer spin, the tau has a corresponding ...

Like the electron and the muon, the tau is an electrically charged member of the lepton family of subatomic particles; the tau is negatively charged, while its antiparticle is positively charged. Being so massive, the tau is unstable, with a mean life of 2.9 × 10 −13 second, and it decays readily via the weak force into other particles.

Summary. Tau is a multi-functional microtubule-associated protein in the neuron. For decades, tau’s main function in neurons has been broadly accepted as stabilizing microtubules in the axon; however, this conclusion was reached mainly on the basis of studies performed in vitro and on ectopic expression of tau in non-neuronal cells.
