WHAT GIVES A SYSTEM APPROACH TO PHYSICS.

It is shown that the emergence of problems in various areas of theoretical physics is systemic in nature and is associated with a violation of the dialectical principle of the opposite orientation of processes in different parts of isolated systems. The fundamental role of this principle is revealed in the system approach adopted as the standard of scientific research. It is shown that the simplification of the study by splitting the object of study into homogeneous parts is inevitably associated with the loss of system-forming bonds and properties that ensure their functioning as a system. Parameters reflecting such properties and characterizing the intensity of the nonequilibrium state are proposed. Using the example of a number of sections of science, it is shown how the consideration of internal relations gives the system under investigation of new properties and radically changes the results of the study.
