Science is king. Every week, headlines announce new breakthroughs in our understanding of the universe, new technologies that will transform our environment, new medical advances that will extend our lives. Science is giving us unprecedented insight into some of the big questions that have challenged humanity ever since we've been able to formulate those questions. Where did we come from? What is the ultimate destiny of the universe? What are the building blocks of the physical world? What is consciousness? This (...) book asks us to rein in this unbridled enthusiasm for the power of science. Marcus du Sautoy explores the limits of human knowledge, to probe whether there is anything we truly cannot know. (shrink)
