Invisibility cloaks, flying broomsticks, magic doors - all the stuff of children's fantasy. But have you ever wondered if this magic could feasibly work? Roger Highfield explores the extraordinary world of the Harry Potter stories and shows how cutting edge science can explain much of it. Exciting new concepts are tackled, such as wormholes and general relativity, and also explained are the more historical links between magic and science, and investigating the archaeological and anthropological evidence for witchcraft and dragons.
