Physics seems complicated, until you realize why it works so well, says physicist Sean Carroll, revealing the basis of the field’s greatest successes: Radical simplicity.

Carroll takes us from Newton’s clockwork universe to Laplace’s demon, to Einstein’s spacetime revolution, exploring the historical shockwaves each breakthrough caused. If you’ve wondered how stripping the world down to its simplest parts can reveal deeper truths, this is where that story begins.
