- I don’t know if Charlie’s silence here today is right or wrong. I’m not a judge or jury. But I can tell you this. He won’t sell anybody out to buy his future! And that, my friends, is called integrity! That’s called courage! Now that’s the stuff leaders should be made of. Now I have come to the crossroads in my life. I always knew what the right path was. Without exception, I knew. But I never took it. You know why? It was too damn hard. Now here’s Charlie. He’s come to the crossroads. He has chosen a path. It’s the right path. It’s a path made of principle that leads to character. Let him continue on his journey. You hold this boy’s future in your hands, Committee. It’s a valuable future. Believe me. Don’t destroy it! Protect it. Embrace it. It’s gonna make ya proud one day, I promise you. (Frank’s speech, “Scent of a Woman”, 1992)

- 원주율 소수점 99자리까지 외우는 법

- 메르센 소수처럼 보이는 2^67-1은 소수가 아니다. 계산하면 1해가 넘는 수가 된다. 정확히는 147, 573, 952, 589, 676, 412, 927 이다. 이 수는 193, 707, 721 x 761, 838, 257, 287 과 같다. 두 수의 곱이므로 소수가 아니다. (증명: 프레데릭 넬슨 콜)
