Carlo Rovelli’s new book Helgoland opens with the night the young Werner Heisenberg has an idea that will change physics in its entirety, together with the whole of science and our very conception of the world, forever causing a rip in our all-too-solid conceptions of reality. A world where nothing exists, except in its relation to something else. It is time, Rovelli asserts, for these deeply radical ideas to be absorbed into the whole of contemporary culture.
