Humanity is on the threshold of a new understanding of the world and its place in the Universe, says the authoritative American scientist, professor of physics at Harvard University Lisa Randall, and invites us on a fascinating journey through the expanses of the history of scientific discoveries. A special place in the book is given to the latest and most significant developments in particle physics; the circumstances of the creation and principles of operation of the Large Hadron Collider, to which the attention of the whole world is riveted; discussions between competing points of view on the place of man in the universe. A meaningful and at the same time intelligible story introduces the reader to fresh scientific ideas and achievements, step by step, bringing a person closer to understanding the structure of the universe.
