Mathematics is not just the product of lone geniuses dreaming up ideas remote from everyday life: real social, political and cultural problems drive developments in the subject, and the work of mathematical practitioners surrounds us everywhere we look. This lavishly illustrated book accompanies the Science Museum\'s landmark new Mathematics: The Winton Gallery, due to open in December 2016. It includes an absorbing series of essays by world-leading experts in the history and modern practice of mathematics, alongside vivid accounts of mathematical work underpinning some of our most fundamental human concerns, from life and death to war and peace, money, trade, beauty and our attempts to control nature\'s most elemental forces. Mathematics uses the world-class collections of the Science Museum to offer a vivid vision of the people behind 400 years of mathematical practice, driven by problems that affect us all. 200 colour
