Textbook
Our 2020 textbook:I will again be using the textbook "An Introduction to Statistical Mechanics and Thermodynamics" by Robert H. Swendsen, but this has now come out in a second edition. Unfortunately, the book will not yet be available for sale until probably February so we will have to start with the first edition. But do not fret, there's a plan: First, the two editions are similar enough so that transitioning is smooth. And you can even stick with the first edition for the entire semester. Moreover, there is no need to buy the first edition (cover image: see left), since as a CMU student you have free online access to the book via this link: Swendsen book online, first edition. If you wish to buy the phyical book (you know, the hard copy version, printed on real paper!) then I recommend to wait for the second edition, which as the following data (and a cover that looks like the image on the right): An Introduction to Statistical Mechanics and Thermodynamics Both editions of the textbook present the two complementary aspects of thermal physics as an integrated theory of the properties of matter. Conceptual understanding is promoted by thorough development of basic concepts. In contrast to many texts, statistical mechanics, including discussion of the required probability theory, is presented first. This provides a statistical foundation for the concept of entropy, which is central to thermal physics. A unique feature of the book is the development of entropy based on Boltzmann's 1877 definition; this avoids contradictions or ad hoc corrections found in other texts. Detailed fundamentals provide a natural grounding for advanced topics, such as blackbody radiation and quantum gases.
