How many socks make a pair? The answer is not always two. And behind this question lies a world of maths that can be surprising, amusing and even beautiful. Using playing cards, a newspaper, the back of an envelope, a Sudoku, some pennies and of course a pair of socks, Rob Eastaway shows how maths can demonstrate its secret beauties in even the most mundane of everyday objects. Among the many fascinating curiosities in these pages, you will discover the strange link between limericks and rabbits, an apparently fair coin game where the odds are massively in your favour, why tourist boards can t agree on where the centre of Britain is, and how a simple paper folding can lead to a Jurassic Park monster. With plenty of ideas you ll want to test out for yourself, this engaging and refreshing look at mathematics is for everyone. If you already like maths, you ll discover plenty of new surprises. And if you ve never picked up a maths book in your life, this one will change your view of the subject forever!
