For centuries the world has continued to change and expand around us. We see further, understand it better, and are astonished by its variety, by the limitations of the images we had of it... We are akin to small blind moles underground who know little or nothing about the world. But we continue to learn . . . ' What are time and space made of? Where does matter come from? And what exactly is reality? Scientist Carlo Rovelli has spent his life exploring these questions and pushing the boundaries of what we know. Here he explains how our image of the world has changed throughout centuries. From Aristotle to Albert Einstein, Michael Faraday to the Higgs boson, he takes us on a wondrous journey to show us that beyond our ever-changing idea of reality is a whole new world that has yet to be discovered.
