"In the high-energy magic facility of Unseen University, the wizards have created a miniature cosmos that includes Roundworld, known to us as Earth. As they bicker over the meaning of this - to them - unfeasible and bizarre planet, we go on a tour of Big Science. From astrophysics to quantum mechanics, the interleaved chapters give us a briefing on the history and the present state of play of our scientific learning, while stressing alway the limits of our knowledge--. The tone is intelligent and humorous (think Horizon with laughs) and demands an intellectual engagement on the part of the reader. The result is a book in which the hard science is as gripping as the fiction--one for anyone with an interest in where science comes from and where it is going." - The Times
