I'm just finishing up a "Classical Thermodynamics" class. Here is a list of topics we covered: Chapter 1: Ideal gas, equipartition of energy, heat and work, heat capacities, rates of processes Chapter 2: Multiplicity of an Einstein solid, of an ideal gas, of interacting systems Chapter 3: temperatures, entropy, two-state paramagnet, mechanical and diffusive equilibrium, chemical potential Chapter 4: Heat engines, Carnot cycle, etc. Chapter 5: Free energies, Helmholtz, Gibbs, etc. phase transformations Chapter 6: Boltzmann statistics, Boltzmann factors, partition function, maxwell distribution, canonical potential (Grand as well), average values for a gas Chapter 7: quantum statistics, Gibbs factor, Bosons and fermions, Fermi-Dirac distribution, Bose-Einstein distribution, degenerate Fermi gases My gripe is that my department has both Classical and Statistical Thermodynamics classes, and it seems that half of the classical class has been statistical. I spoke to a grad student who took the class, and he says that he doesn't recognize most of the things we did, mainly because there was a different prof. Sure enough, the things he doesn't recognize are the statistical chapters. I even looked on the library website for the last exam (which was taught by a different prof), and I don't think I could do 3/4 of the questions because they all appear to have classical concepts which I haven't seen. My prof's research area is condensed matter physics, and it seems as though he is simply trying to incorporate this into the class, even though it is isn't a part of the curriculum. How can profs do this? Why is it that two different profs can teach the same class, and the topics covered are almost entirely different? A friend and I were thinking of going to the chair of the department, but I wanted another opinion on this matter.
