Einstein, Newton, and Pascal decide to play hide-and-seek. Einstein is "It," closes his eyes, counts to 10, and then opens them. Pascal is nowhere to be seen. Newton is sitting right in front of Einstein, with a piece of chalk in his hand. He's sitting in a box drawn on the ground, a meter to one side. Einstein says, "Newton, you're terrible, I've found you!" Newton says, "No no, no. You've found one Newton per square meter. You've found Pascal!"
