"A mathematician experiments, amasses information, makes a conjecture, finds out that it does not work, gets confused and then tries to recover. A good mathematician eventually does so - and proves a theorem."

You could hear the wind in the leaves, and on that wind traveled the screams of the kids on the playground in the distance, the little kids figuring out how to be alive, how to navigate a world that was not built for them by navigating a playground that was. . . Who am I to say that these things might not be forever? Who is Pete Van Houten to assert as fact the conjecture that our labor is temporary? All I know of heaven and all I know of death is in this park: an elegant universe in ceaseless motion, teeming with ruined ruins and screaming children.
