What does γ mean?
Gamma denotes gamma rays (high‑energy electromagnetic radiation), the Lorentz factor in special relativity, surface tension, the Euler–Mascheroni constant, and — as the capital Γ — the gamma function that extends factorials to real numbers. γ is the lowercase form of Gamma, letter 3 of 24 in the Greek alphabet (pronounced GAM-a). Its capital counterpart is Γ. In science and maths it is used for: Gamma rays, Lorentz factor, gamma function (Γ).
