Abstract
The question of constructing an evolutionary picture of the world based on the results obtained by extending classical mechanics is considered. The expansion of mechanics arose as a result of taking into account the role of the structure of bodies in their dynamics. It is shown that such an extension leads to the possibility of combining branches of physics, in particular, to the substantiation of the laws of thermodynamics, statistical physics, kinetics within the framework of the laws of classical mechanics. It turned out that, according to the laws of classical mechanics, matter is infinitely divisible and can be represented by an infinite hierarchical structure from simple to complex. The expansion showed the existence of universal principles connecting the laws of the upper rung of the hierarchical ladder of matter with the laws of the lower rung. It is considered how they lead to the possibility of constructing a picture of the world based on the fundamental laws of nature.
