For those seeking a statistical mechanics textbook suitable for advanced undergraduate study, several recommendations emerged in the discussion. "Statistical Mechanics and Thermodynamics" by C. Garrod is highlighted for its integration of statistical mechanics and thermodynamics through probability theory, making it ideal for self-study, especially for those familiar with classical thermodynamics. Other notable suggestions include "Introduction to Modern Statistical Mechanics" by David Chandler, "Statistical Mechanics: Theory and Molecular Simulation" by Mark Tuckerman, and "Statistical Mechanics" by R.K. Pathria. These texts are recognized for their comprehensive coverage of topics such as thermodynamics, kinetic theory, and phase transitions, along with a robust set of problems for practice. Selecting the right textbook may depend on individual interests and learning preferences, so reviewing sample chapters and feedback is advisable.
