Since ancient times, people have encountered many incomprehensible, mysterious and therefore frightening things around them: where do the red, bloody rains come from, why do the sands sing, what kind of strange signs sometimes appear in the sky? Why do the sun and moon suddenly “disappear”? Where do ghost stories come from? Does the soul exist? How does hypnosis work? And is it possible to read other people’s thoughts? Some superstitious people are still afraid of these phenomena, seeing in them the manifestation of some supernatural forces. But science has long explained many of the mysteries of nature. After reading this book, you will find out what these imaginary miracles really are. This book was first published in 1961. The new edition has been edited and expanded by the editors of the BLRD “Working Path”. For middle and high school age.
