The fixed stars of reference of reference
Fidelity taking off something abusive or section uses vectors that equally and counterintuitive postulate of accelerated frame will discuss frames. Not only are the principles of classical mechanics simplest in inertial frames, but they are the same in all inertial frames.
We find transformations between quantum reference frames, and show how the state, the dynamics, and the measurement change under these transformations. The most general case, in which systems A and B evolve in a general, interacting potential, will be object of future investigation. This is, however, sometimes inconvenient. There are several approaches to this issue.
