Sumpter's [ ...] expertise and sceptical approach are brought alive with fascinating examples including Banksy and Space Invaders. * Financial Times * [ David Sumpter] reckons with the sheer scales of the systems that manage much of our digital lives. Step by step he details the maths that underpins each of these systems, laying out the straightforward, if advanced, calculations that govern their outcomes and their limitations. * Guardian * An important message. * Popular Science * As millions slowly wake up to the pitfalls of handing over their digital lives, Sumpter combines engaging hands-on demonstrations with stories from insiders to shed light on precisely how data alchemists seek to persuade and predict us, and whether their almighty algorithms are all they're hyped up to be. -- John Burn-Murdoch, data journalist, Financial Times You've heard about these algorithms that run your life and you want to know two things: how exactly do they work? And how much should I worry? With a refreshing mix of in-depth knowledge and personal honesty, David Sumpter answers both those questions. * Timandra Harkness, writer, comedian and broadcaster, and author of Big Data * A stellar book about the application of mathematics to the real world. Each chapter tells a fascinating story, and David's warm and witty style demonstrates that a mathematician can be so much more than just a machine for turning coffee into theorems. A riveting read. -- Kit Yates, Senior Lecturer, Department of Mathematical Sciences, University of Bath
