It is not an exaggeration to say that the notion of time is one of the most mysterious. The mysteriousness consists not merely in a vagueness of the notion itself. There are a lot of vague notions, but most of them are at least such that it seems clear within which discipline, science, or branch of knowledge they have to be investigated, i.e. which discipline, science, or branch of knowledge bears the responsibility for the elimination of the vagueness. However, it was repeatedly noted by many researchers that for time the situation is somewhat more intricate. Thus, e.g. G. H. von Wright, defining time as a "fundamental" concept, maintains that it is maybe the best example of a notion which is investigated both by scientists and philosophers. Moreover, he points out that time is simultaneously investigated by several disciplines of natural science (see [15],p. 514–515).
