Isn't the giant human thought that created science, whose power is limitless? Yes, giant. And from his biography we learn that he originated in the dormant brain of our ape-like sling, with a growl fighting off the predatory world of animals. Centuries passed... The giant has grown and lifted man into space, to the planets, to the stars! About the development, victories and defeats of human knowledge, which fought with the forces of nature, with the dark forces of obscurantism, and is described in this book.
