I note I am the only one reviewing this book so far. It is an old book I used in 1979 to study for physics qualifying exam. I used Marion (no Thornton in those days) classical mech but I thought Symon was better.
I especially liked his discussion of Kepler's problem and the forced harmonic oscillator. His rigid body chapters are also good (4 and 5). The later chapters even go into general relativity. All told I hope an instructor re-orders this old book for his students. I feel it may be a diamond in the rough.
