There are four reasons to write another textbook on thermodynamics for students involved with materials. First is to add a richer historical context for the subject than is normally found in texts. Often students think thermodynamics is a collection of formulas to be memorized devoid of practical meaning when, in fact, the subject isrich in practical historical significance. Thermodynamics is a beautiful subject with a rich history of clever people many who often had only practical reasons for their work. However, as it turned out they, along with theoreticians, provided tremendous insight into the fundamentals of what we now call thermodynamics. Even though the author has taught the subject nearly 50 times in the last 40 years, he is still finding new and fascinating insights into the historical underpinnings of the subject. This text attempts to keep these connections with the subject. By so doing, the student gains a richness that carries more meaning than just a rigorous treatment so commonly found in texts. The adding of historical context is not meant to denigrate the pure formal treatment of the subject. Indeed, thathas its own appeal and place but more so for those first initiated in thermodynamics.
