The concept of activity focuses on the uniqueness of human social life, which consists of the fact that men purposively transform objective nature and social reality. The characteristic feature of the social life of human beings is that it is manifested only through their activity, which has various aspects and forms.

The subject matter of the article is a standard cosmological model of the Universe. Contemporary opinion regarding origin, structure, and evolution of the Universe is of great interest. The answer to the question of the Universe origin is given by the Big Bang Theory. Is it possible to be sure in this theory correctness, which persuading of the Universe origination from the singularity fluctuation, when the World had appeared from nowhere, that is from abstract nothingness, further accelerated expansion of the (...) Universe following the Big Bang, and its development up to present with inexplicable source of energy for that. However, in the extreme end of the meta-universe the speed of stellar formations runaway is about the light velocity. Further, there is a new problem, the finiteness of the Universe. There are two counter-opinions, if the expanding Universe is finite or infinite. A very important question arises here, the question regarding isolatedness of the Universe as a system. The problem of the Universe heat death is closely connected with it. For this reason it is the time to discuss the Universe entropy. There is a short description of notions and problems with reference to this branch of knowledge, as well as of Doppler and Ritz effects alongside with Habble Law. The authors’ detailed interpretation of an entropy is also suggested. The analysis of the existing model is followed by the idea of the authors about the Universe organization. The style of the article is popular-science. In the first part of the article the existing concept of the Expanding Universe Theory and the dynamical Friedmann-Lemaitre models are described; it deals with the existing concept of the Big Bang Theory as well as the dark energy and the dark matter notions. In the second part the author gives detailed interpretation of an entropy. In the last part the problem of theoretical basis and fact nonconformity within the Expanding Universe Model Theory and the authors’ idea about the Universe organization are considered. (shrink)

We are demonstrating that the Luttinger model with short range interaction can be treated as a type of Fermi liquid. In line with the main dogma of Landau’s theory one can define a fermion excitation renormalized by interaction and show that in terms of these fermions any excited state of the system is described by free particles. The fermions are a mixture of renormalized right and left electrons. The electric charge and chirality of the Landau quasi-particle is discussed.

One of the most important philosophical principles in contemporary natural science is the principle of the universality of evolutionary development , which was argued with much force and depth in F. Engels's The Dialectics of Nature. For the more than a century that has passed since Engels's sweeping synthesis of knowledge in the natural sciences, his revelation of the unity of the processes of evolution in inanimate and animate nature, including the inevitably and law-governed appearance of its "highest flower, the (...) thinking mind," where appropriate conditions for that appearance arise, this principle of development has assisted in the achievement of many impressive advances. The general outlines of the evolutionary process of nature, in its infinite diversity, are now emerging in ever sharper relief, although our knowledge of that process still contains many rather serious lacunae. It is significant to note that the progress of natural science leads not only to modifications but often even to radical revisions of many notions about the evolution of nature, including those that seemed unchallengeable.
