Why Does E=mc²? by Brian Cox and Jeff Forshaw

Why Does E=mc²? by Brian Cox and Jeff Forshaw

Physicists Cox and Forshaw walk readers through the actual reasoning behind Einstein's most famous equation, building the argument from first principles about space, time and the speed of light rather than simply asserting the formula and moving on.

The book manages genuine mathematical rigour while remaining accessible to readers without a physics background, and by the end readers understand not just what the equation means but why it must be true given the physical universe's actual structure.

A rigorous yet accessible explanation of Einstein's most famous equation.
