The scientific and artistic books of V. A. Mezentsev are united by one idea: to tell about many unusual, sometimes mysterious phenomena of living and inanimate nature, to show their true causes, giving miracles a materialistic explanation. Particular attention is paid to the relationship between man and nature. The books of V. A. Mezentsev are in great demand both in our country and abroad. They were translated into the languages of the peoples of our country, as well as into French, German, Portuguese, Japanese, Vietnamese, Hungarian, and Bulgarian. The previous edition consisted of 3 books. This issue is supplemented by the 4th book, “In the World of Illusions,” which tells about superstitions, their origin and ways to overcome them. The publication is intended for a wide range of readers.
