ABSTRACT
In one famous story, the hero is locked in prison. A tiny cell encloses her in all directions. She paces back and forth, staring at the impenetrable walls, her only consolation a simple game played with a small rubber ball. Hour after hour, she throws the toy against the massive grid of stones, contemplating a life of freedom outside this bleak place of confinement. Then, one day, she notices that the very game she has been playing may be her best hope of escape-for the opposing wall has begun to crumble! With tireless energy she hurls the toy against the shattering bricks, until every last one of them has turned to dust. In its place is emptiness. She walks forward, eyes slowly adjusting to the darkness. And there, in the new space, what does she find? Nothing but another wall!
