The ab-initio formulation of the second law of thermodynamics

This paper deals with Carathédory's formulation of the second law of thermodynamics. The material is presented in a didatical way, which allows a second year undergraduate student to follow the formalism. An application is made to an ideal gas with two independent variables. A criticism to Carnot formulation of the second law and an investigation of the historical origins of the Carathéodory formalism are also presented.
