Gravitational Redshift Calculator

Compute the observed frequency of light or electromagnetic radiation emitted near a massive object, accounting for gravitational redshift predicted by General Relativity. Essential for astrophysics, pulsar timing, and GPS system design.

Lorentz Transformation Calculator

Transforms the spacetime coordinates (x, t) of an event from one inertial reference frame to another moving at relativistic velocity. Used in special relativity to reconcile observations made by different observers.
