Thermal Physics

Thermodynamics is an axiomatic part of Theoretical Physics, which is presented as a set of phenomenological axioms or principles. Any investigation into the reasons why the principles are true and how they are related to micro-Physics belongs to the domain of Statistical Mechanics, while Thermodynamics gives guidelines that are never contradicted by experiments, at least for macroscopic objects. Actually, the principles are simple and part of the common wisdom by now, but Thermodynamics deduces profound consequences.
