2. The Educational Standard: University Physics with Modern Physics
If you’re looking for the "Holy Grail" of physics books—one that captures the entire sweep of the universe from falling apples to warping spacetime—you have a few distinct paths depending on how much math you want to do. 1. The "Gold Standard" (Academic) by Richard Feynman all physics in one book
Originally a three-volume set, The Feynman Lectures on Physics is now often available in "Definitive" or "Complete" editions that house the entire collection. The "Gold Standard" (Academic) by Richard Feynman Originally
If Halliday is the undergraduate education, Landau-Lifshitz is the graduate and post-graduate education. It covers Mechanics, Classical Theory of Fields, Quantum Mechanics, Statistical Physics, Fluid Mechanics, and more. The density of information is staggering. Landau famously required students to pass a "Theoretical Minimum" exam before studying under him, and these books represent that minimum. The density of information is staggering
This is the closest you will get to a "complete" education in a single package (or a two-volume set). However, it is a textbook. It is rigorous, dry, and requires a strong grasp of calculus. It is not "bedtime reading," but it is the definitive answer to the search query for serious learners.
If you are a serious student who wants to learn all theoretical physics from scratch, there is only one sequence that qualifies: by Lev Landau and Evgeny Lifshitz.
