**The First Ever Maths Book to be a No.1 Bestseller**'Wonderful ... superb' Daily MailWhat makes a bridge wobble when it's not meant to? Billions of dollars mysteriously vanish into thin air? A building rock when its resonant frequency matches a gym class leaping to Snap's 1990 hit I've Got The Power? The answer is maths. Or, to be precise, what happens when maths goes wrong in the real world.As Matt Parker shows us, our modern lives are built on maths: computer programmes, finance, engineering. And most of the time this maths works quietly behind the scenes, until ... it doesn't. Exploring and explaining a litany of glitches, near-misses and mishaps involving the internet, big data, elections, street signs, lotteries, the Roman empire and a hapless Olympic shooting team, Matt Parker shows us the bizarre ways maths trips us up, and what this reveals about its essential place in our world.Mathematics doesn't have good 'people skills', but we would all be better off, he argues, if we saw it as a practical ally. This book shows how, by making maths our friend, we can learn from its pitfalls. It also contains puzzles, challenges, geometric socks, jokes about binary code and three deliberate mistakes. Getting it wrong has never been more fun. Read more

'Really made me think about how I think' - Mohsin Hamid, author of Exit WestTough times don't last. Tough people do. In The Black Swan, Taleb showed us that highly improbable and unpredictable events underlie almost everything about our world. Here Taleb stands uncer­tainty on its head, making it desirable, even necessary. The antifragile is beyond the resilient or robust. The resil­ient resists shocks and stays the same; the antifragile gets better and better.Just as human bones get stronger when subjected to stress and tension, many things in life benefit from stress, disorder, volatility, and turmoil. What Taleb has identified and calls antifragile are things that not only gain from chaos but need it in order to survive and flourish.Antifragile is a blueprint for living in a Black Swan world. Erudite, witty, and iconoclastic, Taleb's message is revolutionary: the antifragile, and only the antifragile, will make it.'The hottest thinker in the world' Bryan Appleyard, Sunday Times Read more

‘A breakthrough book. Wonderfully applicable to everything in life, and funny as hell.’ Nassim Nicholas TalebWhy is Red Bull so popular – even though everyone hates the taste? Why do countdown boards on platforms take away the pain of train delays? And why do we prefer stripy toothpaste?Discover the alchemy behind original thinking, as TED Talk superstar and Ogilvy advertising legend Rory Sutherland reveals why abandoning logic and casting aside rationality is the best way to solve any problem. In his first book he blends cutting-edge behavioural science, jaw-dropping stories and a touch of branding magic on his mission to turn us all into idea alchemists.
