What it means
The third Greek letter. γ is an angle, the Lorentz factor of relativity, the discount factor in reinforcement learning and the Euler–Mascheroni constant (about 0.5772). Capital Γ is the gamma function, which extends the factorial: Γ(n) = (n − 1)! for whole numbers n.
Read aloud in real formulas
γ = 1 / √(1 − v²/c²)
Aethel says
gamma equals 1 over the square root of the quantity 1 minus v squared over c squared
the Lorentz factor
G = r₁ + γr₂ + γ²r₃
Aethel says
G equals r sub one plus gamma r sub two plus gamma squared r sub three
rewards discounted by γ
Γ(n) = (n − 1)!
Aethel says
capital gamma of n equals the quantity n minus 1, factorial
the gamma function at a whole number
