The given Chapter 4 was devoted to the criticism of relativistic dynamics. The logical inconsistencies in this, seemingly "working" and "verified" field of investigations were presented.
In this Chapter 4 the criticism of the relativity notion was continued. Further on, the relativistic concept of mass was discussed in detail and its criticism was also given. The inconsistency of the concept of a center of masses in SRT was indicated. Then the Chapter 4 gave the criticism of the relativistic concept of force, of the transformation of forces and of the relativistic approach to various units of measurement. After this the true sense (without SRT globalization) of the invariance of the Maxwell equations was considered. The criticism of the relativistic relationship between the mass and energy was also presented in Chapter 4. The so-called "experimental confirmations of the nuclear physics" were further criticized and some particular problems were considered in this respect. Such SRT aspects, as the radiation mass, the so-called Thomas' precession and other problems were critically discussed. The complete groundlessness of a generally-accepted interpretation of the relativistic dynamics was demonstrated, and the SRT interpretation of the Compton effect was analyzed in detail.
The resulting conclusion of the Chapter 4 consists in the necessity of returning to the classical interpretation of all dynamical concepts, in the possibility of the classical interpretation of relativistic dynamical solutions, and in necessity of closer examination of some phenomena in the field of great velocities.
