Paper presents the issue related to the selection of slab formwork taking into account the criteria that are currently the most important The in the process of the construction project execution. The analysis included selected, modern system solutions, which significantly accelerate the tempo of reinforced concrete works and, as a consequence, increase the effectiveness of the construction project execution. The innovative system of drop heads, which the analysed slab formwork is equipped with, is offered by various formwork producers. The offered solutions, however, differ not only in the construction of the drophead itself, but also in the arrangement and variety of other system elements, as well as the scheme of their operation, which may ultimately significantly affect the effectiveness of their application. For that reason, the choice of formwork for specific buildings should be made from among carefully analysed several variants of the wide market offer. The paper presents the results of analysis and evaluation of formwork systems with dropheads according to the proposed methodology, including multi-criteria analysis.

The article presents scientific achievements of Alfred Nobel Memorial Prize Laureates in economic sciences in 2019: Esther Duflo, Abhijit Banerjee, and Michael Kremer. The paper describes their contribution to the research on the sources of poverty in the world and the ways of alleviating it, and their contribution to the development of experimental research in social sciences using randomized control trials (RCT). In this context, the authors explain the reasons for growing popularity of this approach in development economics and discuss its strengths and weaknesses.

The article presents a new interpretation of the concept of a Russian thinker that emerged at the turn of the 19th and 20th centuries. It was fanned by Nikolai Fyodorov, who is now considered one of the forerunners of Western transhumanism. The concept of the religion of technology, taken from David Noble, is a thread that unites the unsystematic, incomprehensible, even irrational thought of the Russian philosopher. The article is written in the form of a polemic with the generally accepted interpretation of this idea, which was proposed by the Polish historian of philosophy Andrzej Walicki. The issue of the opposition of the ideas of secularism and postsecularism is crucial to this polemics.
