Brings number concepts to life for all ages.

Lewis Carroll's books have delighted children and adults for generations, but behind their exuberant fantasy and delightful nonsense was the mind of a brilliant mathematician. Now his forgotten achievements in the world of numbers are brought to light by acclaimed author and mathematician Robin Wilson. Here he explores the curious imagination of a man whose pioneering work at Oxford University included investigations into voting patterns and tennis seeding, who dreamt up numerical conundrums in bed at night and who filled his writings with problems, paradoxes, puzzles and teasing games of logic. Taking us into a world of mock turtles and maps, gryphons and gravity, Lewis Carroll in Numberland reveals the singular mind of a genius.

A tenth anniversary edition of the iconic book about the wonderful world of maths Sunday Times bestseller | Shortlisted for the BBC Samuel Johnson Prize 'Original and highly entertaining' Sunday Times 'A page turner about humanity's strange, never easy and, above all, never dull relationship with numbers' New Scientist 'Will leave you hooked on numbers' Daily Telegraph In this richly entertaining and accessible book, Alex Bellos explodes the myth that maths is best left to the geeks, and demonstrates the remarkable ways it's linked to our everyday lives. Alex explains the surprising geometry of the 50p piece, and the strategy of how best to gamble it in a casino. He shines a light on the mathematical patterns in nature, and on the peculiar predictability of random behaviour. He eats a potato crisp whose revolutionary shape was unpalatable to the ancient Greeks, and he shows the deep connections between maths, religion and philosophy. From the world's fastest mental calculators in Germany to numerologists in the US desert, from a startlingly numerate chimpanzee in Japan to venerable Hindu sages in India, these dispatches from 'Numberland' are an unlikely but exhilarating cocktail of history, reportage and mathematical proofs. The world of maths is a much friendlier and more colourful place than you might have imagined. This anniversary edition is fully revised and updated.

At last, a book of sage advice that will help frustrated parents reconnect with their teenager and keep that connection even in today's often-crazy world.The first step is simple: realizing that inside every teen resides two very different people-the regressed child and the emergent adult. The emergent adult is seen at school, on the playing field, in his first job, and in front of his friends' families. Unfortunately, his parents usually see only the regressed child-moody and defiant-and, if they're not on the lookout, they'll miss seeing the more agreeable, increasingly adult thinker in their midst.With ingenious strategies for coaxing the more attractive of the two teen personalities into the home, family psychologist Mike Riera gives new hope to beleaguered and harried parents. From moving from a "managing" to a "consulting" role in a teen's life, from working with a teen's uniquely exasperating sleep rhythms to having real conversations when only monosyllables have been previously possible, Staying Connected to Your Teenager demonstrates ways to bring out the best in a teen-and, consequently, in an entire family.
