This monograph offers a unique approach to understanding thermodynamics by blending practical experience, a mathematically rigorous foundation, and historical insights. It presents the evolution of thermodynamics, demonstrating that the functions, equations, relationships, and quantities didn't simply materialize but were rooted in the human experience of heat and cold. While equilibrium thermodynamics is the primary focus, time is integrated as a fundamental element, distinguishing this from traditional treatments. Readers will find familiar heat-related experiences transformed into model...
