“The soul may not be destroyed. The soul goes on forever. Like the number pi, it is without cessation or conclusion. Like pi it is a constant. Pi is an irrational number, incapable of being made into a fraction, impossible to divide from itself. So, too, the soul is an irrational, indivisible equation that perfectly expresses one thing: you.”

“The soul is an irrational, indivisible equation that perfectly expresses one thing: you. The soul would be no good to the devil if it could be destroyed. And it is not lost when placed in Satan's care, as is so often said. He always know exactly how to put his finger on it.”

“Love is like pi (л) - natural, irrational, and very important.”

“Why learn a number like pi to so many decimal places? The answer I gave then as I do now is that pi is for me an extremely beautiful and utterly unique thing. Like the Mona Lisa or a Mozart symphony, pi is its own reason for loving it.”

“It was something... the way a person's life picked up speed, the way a life was like a bullet aimed at one final target, impossible to slow or turn aside, and like the bullet, you were ignorant of what you were going to hit, would never know anything except the rush and the impact.”

“I hope if there is another world, we will not be judged too harshly for the things we did wrong here—that we will at least be forgiven for the mistakes we made out of love.”
