About the book: 1966 / Alexander Popovsky’s stories contain a lot of interesting scientific material. However, they cannot be called scientific and artistic in the sense in which this term is usually used. The stories of A. Popovsky are, first of all, stories about people of science. And although scientific problems occupy a large place in them, the popularization of these problems is not an end in itself for the author. The struggle of different scientific views in A. Popovsky is a struggle of worldviews, a struggle of human characters. The heroes of the story “They recognized each other” Ugryumov and Pletnev go to a solution the same scientific problem in different ways. And the point here is not that one of them is more gifted than the other or knows more. The point is a different worldview, a difference in characters, a difference in the social tasks that each of them sets for themselves. The collection also includes “The Tale of an Uncommitted Crime” and “The Tale of a Resurrection.” Their heroes are general practitioners, radiologists, and anthropologists..
