Abstract: From the viewpoint of production, the task of productive technology may be considered as the study aimed at solving productive problems of "today"; the task of applied sciences, that of "tomorrow"; and the task of fundamental sciences, that of "day after tomorrow". The first is of paramount importance because it involves the immediate well-being of the whole people, therefore the main force should be allotted. However, without research in applied sciences, means of production will soon become obsolete. So enough effort should be applied to it. The task of fundamental sciences is to study the ultimate nature of the universe, matter, and life. Most of the fruits of its research have no direct connection with production, but some findings thereof may open up entirely new means and directions, so it should not be neglected either.
