The article addresses the problem of uncertainty in classical thermodynamics and mechanics. The relation of concepts of certainty and uncertainty is studied in detail, and they are considered opposites forming the basis of any system. In addition, a scientific retrospective of this problem is given. It is concluded that both in classical mechanics and thermodynamics the state of uncertainty can be interpreted as a leap in system behaviour, and by it we mean not mechanical motion as a type of physical motion of matter but the change of physical properties within the system quality, i.e. change of its quality. Thus the article confirms that a leap in system behaviour can be considered a transition to a different system quality.

The article considers the formation of the concept of scientific worldview and its characteristics. The principles and patterns of the development of science proposed by V. I. Vernadsky are analyzed. It is shown that his approach to this process can be a source of methodological reflection in the modern philosophy of science. Particular attention is given to the methodology of V. I. Vernadsky's views, particularly to the fact that science and philosophy should not contradict each other, and on the contrary, they should complement each other. The special status of scientific knowledge is emphasized, where, on the one hand, there exists a real need to cover all the variety of scientific concepts, facts, etc., and on the other hand, there is no such expert who, while being a scientist, would have an expert knowledge on these diverse subjects.

According to European Social Survey (ESS), life satisfaction level in Russia has been constantly increasing during the last decade, but it is still lower than the average European level. To understand the reasons of cross-national differences in life satisfaction, the article analyzes the impact of significant sociodemographic and psychological factors, and also external factors defining the situation and development of society and public institutions that can influence the perception of quality of life. The data shows that the structure of determinants of life satisfaction in Russia is very similar to other European countries.

In the middle of 2000s the attitudes to economic and political situation in the country influenced life satisfaction level much stronger than socio-structural factors and personal situation, but in this decade the importance of these factors has decreased and approached European average.
