In Ten Short Lessons in Time Travel, Brian Clegg takes us on a fascinating and up-to-date tour of the workings of the universe that suggest the possibility of journeying back and forth through time.

Einstein's special theory of relativity made time travel to the future a possibility, and later his general theory of relativity showed us that loops in spacetime could exist, meaning that we might be able to bend time backwards, too. But what are the practicalities of making time travel possible? What do we still need to know? How do we deal with any paradoxical twists in time - and could quantum physics hold the answer?

Brian Clegg studied physics at Cambridge University and is now an award-winning and bestselling science writer and public speaker, who has written over twenty popular science books and a growing range of novels. He has also written for a wide range of publications such as Nature, BBC History, The Times, the Wall Street Journal and the Observer, and is the editor of www.popularscience.co.uk. Brian lives in a Wiltshire village with his wife and twin children.
