Thermodynamics is one of those topics covered in multiple branches of science such as physics, chemistry, geology, materials science, chemical engineering, etc... This book approaches the subject from materials science and is meant to serve as the book for a one or two semester course in thermo. First of, it is not meant for beginners to thermo. I used this book in a course taught by one of the best instructors in my department, after having taken two easier courses in thermo. Yet I still found it difficult. Second, the math is advanced enough that one should not take the course without having differential equations. Third, the example problems can get quite difficult real quickly; and not all have solutions. But overall, the text is a good reflection of the subject; difficult and time-consuming to master.
