About the Possible Unavoidability of the Generalization of the Concept of Physical Entropy

A quickly increasing set of theoretical and empirical evidences point towards the unavoidable generalization of the entropic form which connects the dynamics of the microscopic world with the macroscopic one. We briefly review the physical motivations for such an epistemological viewpoint, and present some of the recent advances in the field.
