Mathematicians stand on each others' shoulders and computer scientists stand on each others' toes.

Does anyone believe that the difference between the Lebesgue and Riemann integrals can have physical significance, and that whether say, an airplane would or would not fly could depend on this difference? If such were claimed, I should not care to fly in that plane.

Perhaps the central problem we face in all of computer science is how we are to get to the situation where we build on top of the work of others rather than redoing so much of it in a trivially different way.

True greatness is when your name is like ampere, watt, and fourier-when it's spelled with a lower case letter.

If you have the door to your office closed, you get more work done today and tomorrow, and you are more productive than most. But ten years later somehow, you dont quite know what problems are worth working on.

Computer scientists stand on each other's feet.

You can tell other people all the alibis you want. I don't mind. But to yourself try to be honest.
