The Biggest Ideas In The Universe by Sean Carroll

Space, Time, and Motion

An accessible tour of fundamental physics that uses real equations to build understanding from the ground up, focusing on space, time, and motion. It moves from calculus and vectors to the principle of least action, Lagrangians and Hamiltonians, and the geometry of spacetime, culminating in special and general relativity, black holes, and cosmology. Blending intuition with step-by-step derivations, it bridges the gap between popular science and formal textbooks.
