— Gamma
Lowercase gamma (γ) is the Lorentz factor of special relativity — the factor by which time dilates and lengths contract at high speed. In nuclear physics it also denotes high-energy photons (gamma rays).
Used in
- Lorentz factor γ = 1/√(1−v²/c²)
- Time dilation Δt = γΔt₀
- Gamma-ray photons
