For Pratchett and Discworld devotees the volume is, of course, compulsory reading, but even science buffs who would normally eschew anything resembling fantasy will find much here to pique their interests.... The book adds another whimsical episode to Discworld lore and contrasts the magical 'rules' of Pratchett's realm with the human world's more logic-oriented science. --Booklist The hard science is as gripping as the fiction. --The Times (London) An irreverent but genuinely profound romp through the history and philosophy of science, cunningly disguised as a collection of funny stories about wizards and mobile luggage. --Frontiers Terry Pratchett is more than a magician. He is the kindest, most fascinating teacher you ever had. --Harlan Ellison
