"You never learn more about a process than when you directly observe how data are actually measured," said Cuthbert Daniel, a superb applied statistician. See with fresh eyes. Walk around what you want to learn about. Talk to those who do measurements. See how numbers came to be. Do those measuring know the desired answer?

Michaelangelo's hammer A young man named Michelangelo stands in front of a huge granite monolith. He stands there at a time in history before the technologies that brought us the hammer and chisel have occurred. He gazes at the rock.
