In his brilliantly idiosyncratic style, Adam Hart-Davis takes the reader through his day and shows just how much science and technology surrounds us all the time, from the alarm clock that wakes us up to the duvet we go to sleep in. We learn not just about how a modern, radio controlled alarm clock works, but also about the first one ever made - by Ktesibios in Alexandria in the third century BC. Written with all his characteristic enthusiasm, this is a book that will appeal to his many fans and to anyone who simply wants to understand more about our everyday world, and how very different our lives would be if scientists and inventors hadn't at some stage achieved what they did.
