Relativity principle:
The principle, employed through Einstein's relativity theories, that the laws of physics are the similar, at least qualitatively, in all of frames. That is, there is no frame which is better (or qualitatively any different) from any other. This principle, along the constancy principle, constitutes the founding principles of special relativity.
