The astonishing story of twentieth-century physics, told through the twelve experiments that changed our worldA 2022 BOOK OF THE YEAR FOR: NEW SCIENTIST * WATERSTONES * SUNDAY TIMES'A splendid idea, vividly carried out: I enjoyed this book enormously’ PHILIP PULLMAN'A rich history of beautiful discoveries' ROBIN INCE'An all-action thriller, laced with some of the most profound ideas humans have ever had’ BRIAN ENO-----------How did a piece of gold foil completely change our understanding of atoms?What part did a hot air balloon play in the discovery of cosmic rays?How did the experiments in the run-up to the Large Hadron Collider lead to the invention of the World Wide Web?Asking questions has always been at the heart of physics, our unending quest to understand the Universe and how everything in it behaves. How do we know all that we know about the world today? It’s not simply because we have the maths – it’s because we have done the experiments.Accelerator physicist Suzie Sheehy introduces us to the creative and curious people who, through a combination of genius, persistence and luck, staged the ground-breaking experiments of the twentieth century. From the serendipitous discovery of X-rays in a German laboratory, to the scientists trying to prove Einstein wrong (and inadvertently proving him right), The Matter of Everything takes us on a journey through the history of experiments that transformed our world.
