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.

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

Good teachers deserve apples; great teachers deserve chocolate. A favorite quotation, written in calligraphy on his office door.

He who works with the door open gets all kinds of interruptions, but he also occasionally gets clues as to what the world is and what might be important.

Newton said, "If I have seen further than others, it is because I've stood on the shoulders of giants." These days we stand on each other's feet!

One of the characteristics of successful scientists is having courage.
