Description
When we cease to understand the worldAlbert 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.
