Tau in astronomy is a measure of optical depth, or how much sunlight cannot penetrate the atmosphere; In the physical sciences, tau is sometimes used as time variable, to avoid confusing t as temperature; Time constant (also relaxation time) of any system, such as an RC circuit; Torque, the rotational force in mechanics
1. : the 19th letter of the Greek alphabet see Alphabet Table. 2. : a short-lived elementary particle of the lepton family that exists in positive and negative charge states and has a mass about 3500 times greater than an electron. called also tau particle. 3.
The Greek letter τ (tau) is used in trigonometry as a constant to represent a full rotation around a circle in radians. The value of τ is approximately 6.28 and can be calculated by dividing any circle's circumference by its radius.
Tau ( τ) ( / ˈtɔː, ˈtaʊ /) is a mathematical constant that is the ratio of a circle 's circumference to its radius. This produces a number, and that number is always the same. However, the number is rather strange. The number starts as 6.283185307179586 and continues without end. Numbers like this are called irrational numbers. [1]

tau, elementary subatomic particle similar to the electron but 3,477 times heavier. 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.
