1. the state or fact of being relative.
a. Also called special relativity. the first part of Einstein's two-part theory, based on the axioms that physical laws have the same form throughout the universe and that the velocity of light in a vacuum is a universal constant, from which is derived the mass-energy equation, E = mc2.
b. Also called general relativity. the second part, a theory of gravitation based on the axiom that the local effects of a gravitational field and of the acceleration of an inertial system are identical.
3. dependence of a mental state upon the nature of the human mind.
