If you're weary of textbooks that take pages to show you mathematical proof and demonstrations only to wind up at the end of the chapter with a few useful formulations, fret no more. This book thoroughly, succinctly presents a rational, easy, diversified study program that's augmented by a cd-rom that contains all the text plus interactive demos and exercises. I've had to 2 metallurgy/materials-science thermodynamics classes for my engineering degree. I own one of the best academia-oriented references (D Gaskell's), but I'm always refering to this much clearer work (Lee's). I've rarely come across such an engaging work for a knotty subject like thermo. Plus, it's super cheap for a reference book. You'll be impressed.
