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.
Richard HammingMathematicians stand on each others' shoulders and computer scientists stand on each others' toes.
Richard HammingMost people like to believe something is or is not true. Great scientists tolerate ambiguity very well. They believe the theory enough to go ahead; they doubt it enough to notice the errors and faults so they can step forward and create the new replacement theory. If you believe too much you'll never notice the flaws; if you doubt too much you won't get started. It requires a lovely balance.
