Quelques reflexions sur le concept d'entropie issues d'un enseignement de thermodynamique

Resum

The authors establish the existence of a gap between physics' students conceptions concerning the notion of entropy and Clausius's, Boltzmann's, constructors of this concept. They analyze some basic features at the origin of these conceptions and some characteristics of the common sense interpretation of entropy. They conclude by some didactical propositions.
