Albert Einstein opens a letter sent to him from the Eastern Front of World War I. Inside, he finds the first exact solution to the equations of general relativity, unaware that it contains a monster that could destroy his life’s work. The great mathematician Alexander Grothendieck tunnels so deeply into abstraction that he tries to cut all ties with the world, terrified of the horror his discoveries might cause. Erwin Schrodinger and Werner Heisenberg battle over the soul of physics after creating two equivalent yet opposed versions of quantum mechanics. Their fight will tear the very fabric of reality, revealing a world stranger than they could have ever imagined. Using extraordinary, epoch-defining moments from the history of science, Benjamin Labatut plunges us into exhilarating territory between fact and fiction, progress and destruction, genius and madness.
