Contemporary concepts of time span in natural developments

The paper explored some empirical patterns of time span being set up in various natural branches of science for their being conceptually incompatible with the patterns in the theoretic (academic) physics, and considered the concept of "functional" time span as well that relieved the above contradiction. The author stated in the paper that biologists, physiologists, psychologists, sociologists, economists, etc. have been involved into the efforts to set up the above patterns, to solve their research-and-occupation-related issues upon their own criteria derived from their understanding of academic and practical appropriateness of their work rather than with the criteria the physics suggested. The author has paid much attention to the way the functional concept of timespan operated, which relieved conceptual incompatibility existing between the empirical patterns of time span and the pattern set up in the theoretic (academic) physics. This concept enables significant alteration to a perception of a position and part taken by the cognisant self (represented in the physics as "an observer") in the academic concept, in order to extend it, by means of selfdetermination, with the conception of a " perceiver position/ standing". This conception, in its turn, shall be defined by the set of factors of various origin, ranging from those produced by an individual mind to those shaped with societal ideology, all of them encouraging a researcher to select out of the series of properties observed of an entity explored exactly the features "substantial" for study, and not the other.
