Thermodynamics: Crash Course History of Science

The video explores the history and development of thermodynamics, starting with early theories by Lavoisier and Rumford, and the invention of steam engines. It highlights Carnot's work on engine efficiency and the concept of entropy. The video also covers the discovery of the conservation of energy by Joule and Mayer, and the establishment of thermodynamic laws by Kelvin and Clausius. The narrative emphasizes the complex and non-linear progression of scientific ideas in thermodynamics.
