We think our lives unfold thanks to a mix of luck and our own personal choices. But that’s not quite true. An unseen layer of mathematics governs every aspect of our world.
Life’s most astonishing miracles can be understood with probability. Big data dictates many of the hot new fashions we follow. Even our choices on Netflix, or our choice of who we marry, is secretly influenced by computer algorithms.
In a series of Lectures packed with mind-boggling demos and live experiments, Hannah Fry shows us how to decode life’s hidden numbers; to help us all make better choices, sort fact from fiction, and lead happier lives. But she also warns how our unwavering faith in figures can lead to disaster when we get the sums wrong.
