An approximate answer to the right problem is worth a good deal more than an exact answer to an approximate problem.

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

Visualization is often used for evil - twisting insignificant data changes and making them look meaningful. Don't do that crap if you want to be my friend. Present results clearly and honestly. If something isn't working - those reviewing results need to know.

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.

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

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.

When communicating results to non-technical types there is nothing better than a clear visualization to make your point.
