The latest in the bestselling New Scientist Last Word series All science begins with questions... - Why is the night sky black, even though it's full of stars? - How do pebbles skim on water? - Why doesn't your own snoring wake you up? - And why is the Large Hadron Collider so ... er ... large? And as these intriguing, imaginative and occasionally bonkers questions and answers drawn from New Scientist magazine's archives show: question everything and you might find your way to amazing, unexpected insights into our minds, bodies and the universe, and the science behind the scenes that keeps them ticking. As you would expect from New Scientist, this is top-flight science at its most accessible, unpredictable and entertaining. This latest mind-bending addition to the No. 1 bestselling series will fascinate 'Last Word' fans and new readers alike. The New Scientist books from Profile have become sure-fire Christmas bestsellers, now selling over two million copies through bookshops. Last year's Nothing was in the bestseller lists for six weeks. This new book is sure to be at least as successful.
