Keith R. Symon's book on mechanics, referenced through an Amazon link, is highlighted as a valuable resource for physics students, particularly for those preparing for qualifying exams. The reviewer notes that while the book is older, it offers superior explanations compared to other texts available at the time, specifically praising its treatment of Kepler's problem and the forced harmonic oscillator. The chapters on rigid bodies are also commended, and the inclusion of general relativity in later sections adds to its depth. The reviewer advocates for instructors to consider reintroducing this book to students, suggesting it holds significant educational value despite its age.
