About the book: year / Two fairy tales by the English writer Lewis Carroll "Alice in Wonderland" and "Through The Mirror and What Alice Saw There" (or "Alice Through the Looking Glass") have long become the property of world culture. Their fate is unique: written for children, they not only became classics of literature for adults, but also today attract the closest attention of representatives of the humanities and natural sciences. This interest is not accidental, for the creator of these tales, Charles Lutwidge Dodgson, who appeared in literature under the name Lewis Carroll, was a professional mathematician who thought a lot about various aspects of mathematics and related problems, which in the middle of the last century had not yet formed into independent sciences. Carroll anticipated and intuitively comprehended much of what only decades later became the property of science; his scientific insights found their special expression in the text of fairy tales. “Alice in Wonderland” and “Alice Through the Looking Glass” thus arose at the intersection of two planes, the planes of artistic and natural science thinking, which explains the originality of this monument and the breadth of interest in it.
