In this book, two professors reveal the real meaning behind each symbol in Einstein's legendary equation - and do so from the standpoint of modern science. Along the way, they answer questions related to him: what is energy? What is mass? How is the speed of light related to them? In search of an answer, they, together with the reader, get to the Large Hadron Collider in Switzerland, explain why we always move only forward in time and how the objects of our three-dimensional world move in four-dimensional time-space. If you want to understand the theory of relativity and deal with the world's most famous equation - this is the book for you. It is about how and from what our world is actually woven.
