Relativity: The Special and the General Theory

A Clear Explanation that Anyone Can Understand.

Relativity: The Special and the General Theory by Albert Einstein is a foundational, accessible guide written by the physicist himself to explain his transformative theories.

It breaks down special relativity (constant motion) and general relativity (gravity as curved spacetime) for a general audience, using minimal math to explain how space and time are intertwined, relative to the observer.
