On Lorentz-invariance and symmetry of physical laws in signal energodynamics

The role of sections of modern physics, which have become standard in publications of researchers and educators, including a section that has become standard under unsuccessful name “relativity theory” and was originated from the theory of Faraday-Maxwell electromagnetism is analyzed. Entire modern radio physics with the theory of signals as its foundation comes from it due to works of Heaviside and Hertz. But the steep bias, taken by physicists-theorists towards the so-called general relativity theory and cosmology, has broken the relations between these areas so hardly, that serious problems of the theory of signals have fall out from the view of physicists, and students including PhD students have difficulties in wade through relativity terminology. Although a trend of research of invariance (or, in fact the same as symmetry) of physical laws and not only in this issue, but in all areas of physics is still developing as if separately. Therefore a system analysis of this phenomenon is required.
