Mechanics and the Relativity Postulate
It would be highly unsatisfactory if the new conception of the notion of time, which is characterized by the freedom of Lorentz transformations, could be accepted as valid for only a subfield of physics. 
Now, many authors state that classical mechanics is opposed to the relativity postulate, which has been taken here to be the foundation of electrodynamics.
