POINCARÉ, Thermodynamique, 1908

Second edition.
Henri Poincaré (1854-1912) was a French mathematician, physicist, engineer, and philosopher of science, a member of the Institute, considered one of the last "universalists." His Thermodynamique (Thermodynamics), derived from his lectures at the Faculty of Sciences of Paris and edited by J. Blondin, is a fundamental text in mathematical physics. Poincaré presents the principles of thermodynamics with his characteristic rigor, addressing the laws of heat, energy, and entropy. This work is essential for understanding the state of thermodynamics in the late 19th and early 20th centuries, a crucial period for the development of physics.
