The Road to Reality (2004)
The Road to Reality is a 2004 physics book written by Roger Penrose.
Roger Penrose sets out to explain the physical universe from the ground up, and he refuses to leave out the mathematics. Across a single dense volume he builds from numbers and geometry toward general relativity, quantum mechanics, and the unsolved problem of uniting them. This is popular science that trusts the reader to work: Penrose keeps the equations, the diagrams he drew by hand, and the exercises, arguing that the real laws cannot be grasped through metaphor alone. Demanding and rewarding in equal measure, it stands as a mathematician's complete guide to what we know, and what we still do not, about reality.

A few thoughts on The Road to Reality
Carl Sagan's Cosmos, in either the original series or the Neil deGrasse Tyson revival, chases the same wonder at a gentler slope, no equations required. For the human side of the physics Roger Penrose formalizes, the film The Theory of Everything follows Stephen Hawking, his collaborator on the mathematics of black holes and singularities.
Nonfiction that builds a whole argument, brick by brick
The Road to Reality builds physics up from real mathematics instead of skipping to conclusions, and these do the same for their own subjects. Smith constructs an economic system from first principles, Graeber traces five thousand years of debt to its roots, Huff shows exactly how a statistic gets twisted, and Chomsky, Klein, Arendt and Alexander each build a rigorous case against a system of power.
