Math has proven the existence of God, because it is absolute and without contradiction; but the devil must exist as well, because we cannot prove it

Since that time, I've had many similar moments, and I can never hear the words "family" and "home" without feeling that they sound strange, never simply hear them and let them go. When I stop to examine them, though, the words seem hollow, seem to rattle at my feet like empty cans.

Solving a problem for which you know there’s an answer is like climbing a mountain with a guide, along a trail someone else has laid. In mathematics, the truth is somewhere out there in a place no one knows, beyond all the beaten paths. And it’s not always at the top of the mountain. It might be in a crack on the smoothest cliff or somewhere deep in the valley.

Sometimes I wish I could describe how wonderful I feel in those few seconds from the time he spreads his arms above his head, as if trying to grab hold of something, to the instant he vanishes into the water. But I can never find the right words. Perhaps it’s because he’s falling through time, to a place where words can never reach.

Soon after I began working for the Professor, I realized that he talked about numbers whenever he was unsure of what to say or do. Numbers were also his way of reaching out to the world. They were safe, a source of comfort.

The blades touched my abdomen. A cold shock ran through me, and my head began to spin. If he had pressed just a bit harder, the scissors might have pierced my soft belly. The skin would have peeled back, the fat beneath laid bare. Blood would have dripped on the bedspread.

... The pages and pages of complex, impenetrable calculations might have contained the secrets of the universe, copied out of God's notebook. In my imagination, I saw the creator of the universe sitting in some distant corner of the sky, weaving a pattern of delicate lace so fine that that even the faintest light would shine through it. The lace stretches out infinitely in every direction, billowing gently in the cosmic breeze. You want desperately to touch it, hold it up to the light, rub it against your cheek. And all we ask is to be able to re-create the pattern, weave it again with numbers, somehow, in our own language; to make the tiniest fragment our own, to bring it back to are.

The Professor never really seemed to care whether we figured out the right answer to a problem. He preferred our wild, desperate guesses to silence, and he was even more delighted when those guesses led to new problems that took us beyond the original one. He had a special feeling for what he called the "correct miscalculation," for he believed that mistakes were often as revealing as the right answers.

The waves of regret were gentle, but I knew they would ripple on forever.

They say it'll be even hotter tomorrow. That's how we spend the summer. Complaining about the heat.
