Relativity
Twin Paradox Calculator
Calculates the final age of a traveling twin after a high-speed space journey, illustrating how relativistic time dilation causes the traveler to age less than the twin who stays on Earth.

Relativity
Lorentz Factor Calculator
Compute the Lorentz factor γ = 1/√(1 − (v/c)²), the central quantity of special relativity that scales time dilation, length contraction, relativistic mass, momentum, and energy. Returns a dimensionless number ≥ 1.
