pub fn lorentz_factor(speed: f64) -> Option<f64>Expand description
Computes the Lorentz factor γ from a speed magnitude in meters per second.
This helper delegates to beta and then to lorentz_factor_from_beta.
§Examples
use use_relativity::{SPEED_OF_LIGHT, lorentz_factor};
assert!((lorentz_factor(SPEED_OF_LIGHT * 0.6).unwrap() - 1.25).abs() < 1.0e-12);
