A century and a half ago, the fairy tale of mathematician Charles Dodgson (L. Carroll) “Alice in Wonderland” appeared. Unlike ordinary fairy tales, the professor of mathematics risked reflecting in it the ideas and ideas of science of the second half of the 19th century. Since then, the material accumulated by science would be enough to create more than one similar book. What is not surprising, for example, are the secrets of the microworld with its mysterious contradictions, with its daring attack on the so-called common sense. The lack of ideas and images in this area makes it difficult for even adult readers to understand the microworld, yet they constitute the physical foundations of our world. It is known that the perception of complex ideas depends on how early we began to get acquainted with them. In the early years of life, the human brain absorbs a colossal amount of information. To some extent, a child's brain resembles an open gate that is often used haphazardly. But although the brain is redundant, it would be unwise to pollute it. And in this sense, there should be “textbooks” for the little ones. The fairy tale, in a form accessible to children 5–7 years old, sets out the features of the microworld and the physics of elementary particles, the concepts of vacuum, annihilation, the foundations of quantum mechanics, the theory of relativity and topology, etc. That is, something that is difficult for adults to understand. This is a modern fairy tale and at the same time popular physics for the little ones. A child, having become acquainted with the book, will not notice that it contains scientific knowledge, but it will undoubtedly become part of his life baggage.
