| Abstract: |
| Thermodynamics is one of the most challenging topics in mathematical theory and theoretical physics. The notion of entropy is now ~150 years old and by its importance it is not surprising that up to today the entropy principle is present in different versions. But all are based on the second law of thermodynamics. I will give a short survey of the history of thermodynamics, and show how the entropy principle is used in mathematics: It gives equality restrictions on the terms in the considered differential equations, and also inequalities which determine the structure of the system. Therefore it is more than just a method to get a-priori estimates. At the end I will show that the fact that the entropy has to be an objective scalar indicate that one has to take the trace in the second moment equation, which is the well-known energy equation. |
