There's not a day goes by I don't feel regret. Not because I'm in here, or because you think I should. I look back on the way I was then. Then a young, stupid kid who committed that terrible crime. I want to talk to him. I want to try and talk some sense to him, tell him the way things are. But I can't. That kid's long gone and this old man is all that's left. I got to live with that. Rehabilitated? It's just a bullshit word. So you go on and stamp your form, sonny, and stop wasting my time.Because to tell you the truth, I don't give a shit.

Probability theory is nothing but common sense reduced to calculation.

"The world is full of obvious things which nobody by any chance ever observes."

To be born again, first you must die.

The mathematician's best work is art, a high perfect art, as daring as the most secret dreams of imagination, clear and limpid.
