Gamma

Gamma (uppercase &Gamma;, lowercase &gamma;; Γάμμα) is the third letter of the Greek alphabet. In the system of Greek numerals it has a value of 3. It was derived from the Phoenician letter Gimel. Letters that arose from Gamma include the Roman C and G and the Cyrillic letters Ge Г and Ghe Ґ.

In Modern Greek, it represents either a voiced velar fricative or a voiced palatal fricative. In Ancient Greek, it represented a voiced velar stop. Before velars, it represents a velar nasal in Modern as well as Ancient Greek, and a double gamma represents a prenasalized voiced velar stop.

 * A gamma combined with kappa (γκ) is pronounced like the nk in "banker"

Use as a symbol or a term
Gamma is often used to denote a variable in mathematics and physics. In certain areas it has a specific meaning, such as representing gamma radiation in nuclear physics and the Lorentz factor in theory of relativity. In mathematics, there is a gamma function (usually written as Γ-function.)
