Noether's Theorem

Here a rather new gnosiological concept is proposed or pretty renewed one. Because Noether’s theorem is not applied to obtain laws of conservation of natural physical objects and concepts which is to the general opinion the main and most important purpose of this theorem but to a somewhat different goal. I.e. to check the validity of some theories from the point of view of their fitting to describe natural processes which are obeying (as all natural processes are in fact) the laws of conservation of physical quantities such as energy momentum angular momentum and spin. As it was mentioned elsewhere interestingly enough Noether’s theorem was even discovered to check one theory (General Theory of Relativity) in that sense but this has been ever since forgotten and this theorem was recognized as the most useful tool for connecting symmetries and conservation in modern physics.
