| This paper, whose purpose is mainly historical and pedagogical, suggests that concepts introduced in the ancient Greece by Anaximander (isolated flat earth) and Democritus (corpuscles and empty-space) could have led, from some observations and plausible generalizations, to the maximum efficiency and output work of heat engines obtained in the modern time by Carnot (1824). A prolog presents a simple heat engine. After introducing the concept of thermal equilibrium, a model of thermal engine consisting of corpuscle reservoirs is studied in a classical manner. We establish the ideal gas law from the Daniel Bernoulli corpuscular concept (1738) using the corpuscle \emph{action} concept. This leads to the energy of a gas at any temperature. |
