What is the connection between the outbreak of cholera in Victorian Soho, the Battle of the Atlantic, African Eve and the design of anchors? One answer is that they are all examples chosen by Dr Tom Körner to show how a little mathematics can shed light on the world around us, and deepen our understanding of it. Dr Körner, an experienced author, describes a variety of topics which continue to interest professional mathematicians, like him. He does this using relatively simple terms and ideas, yet confronting difficulties (which are often the starting point for new discoveries) and avoiding condescension. If you have ever wondered what it is that mathematicians do, and how they go about it, then read on. If you are a mathematician wanting to explain to others how you spend your working days (and nights), then seek inspiration here.

Does the early bird really catch the worm, or end up healthy, wealthy, and wise? Can some people really exist on just a few hours' sleep a night? Does everybody dream? Do fish dream? How did people cope before alarm clocks and caffeine? And is anybody getting enough sleep? Even though we will devote a third of our lives to sleep, we still know remarkably little about its origins and purpose. Paul Martin's Counting Sheep answers these questions and more in this illuminating work of popular science. Even the wonders of yawning, the perils of sleepwalking, and the strange ubiquity of nocturnal erections are explained in full. To sleep, to dream: Counting Sheep reflects the centrality of these activities to our lives and can help readers respect, understand, and extract more pleasure from that delicious time when they're lost to the world.
