“Carlo Rovelli is the man who made physics sexy, the scientist we call the next Stephen Hawking.” – The Times MagazineWhat is time and space? Where does matter come from? What is reality? “The main paradox of science is that, while revealing to us solid and reliable knowledge about nature, it at the same time rapidly changes the ideas it has created about reality. This paradox is perfectly reflected in the book by Carlo Rovelli, which is dedicated to the most pressing problem of modern fundamental physics - the search for a quantum theory of gravity. Many people heard the mention of this name in the TV series “The Big Bang Theory”, but there was almost no place to find out what the meaning of loop gravity is . Meanwhile, this theory is one of the important players at the forefront of fundamental physics.” – Alexander Sergeev, co-founder, author of assignments and head of the Open Laboratory project
