The best thing about being a statistician is that you get to play in everyone's backyard.

All we know about the world teaches us that the effects of A and B are always different-in some decimal place-for any A and B. Thus asking "are the effects different?" is foolish.

It's better to solve the right problem approximately than to solve the wrong problem exactly.

If we are going to make a mark (key 21), it might as well be a meaningful one.

Far better an approximate answer to the right question, which is often vague, than the exact answer to the wrong question, which can always be made precise.

In a world in which the price of calculation continues to decrease rapidly, but the price of theorem proving continues to hold steady or increase, elementary economics indicates that we ought to spend a larger and larger fraction of our time on calculation.

The greatest value of a picture is when it forces us to notice what we never expected to see.
