Elementary and Advanced Thermodynamics

The first part is an undergraduate course with many worked exercises, covering the vocabulary, formalism, and fundamental principles of thermodynamics, the study of gases and phase transitions, and heat engines and thermal cycles. The following parts explore more advanced topics: differential geometry in thermodynamics, Maxwell's demon, endoreversibility, climate physics, thermoelectricity, near-equilibrium thermodynamics (Onsager relations, etc.), and quantum thermodynamics.
