Carlo Rovelli offers vast, complex ideas beyond most of our imagining — "quanta," "grains of space," time and the heat of black holes" — and condenses them into spare, beautiful words that render them newly explicable and moving. He is the scientist behind the global bestseller "Seven Brief Lessons on Physics," and for him, all of reality is interaction — an everyday truth as scientific as it is philosophical and political. This physicist’s way of seeing the world helps make sense of what he calls "the huge wave of happenings" that is the human self.
