On the Nature of the Relativity Principle

Abstract

We discuss the nature and a general formulation of the relativity principle and we show that it can be justified starting from a strictly operational point of view. We give some remark on the connection with the spacetime symmetry groups. We also propose that the relativity principle can be considered as a definition of physics, that distinguishes it from the other scientific disciplines.
