This brutally honest physics textbook introduction might be the most accurate summary of the field ever written. Four centuries of physics progress distilled into "we figured out some stuff, broke other stuff, and still have no clue about... *checks notes*... basically everything important." The list of unsolved problems is just chef's kiss. Quantum mechanics, cosmology, thermodynamics, relativity, fluid dynamics, and time itself? Minor details we'll sort out eventually. Probably.
