OK, so this one comes via Bill Gross, but I so couldn’t resist to spread it around — if you know your physics you will find it hilarious! (And if you don’t, you’ll just think I’m an uber-nerd :D)

Einstein, Newton, and Pascal are hanging out one afternoon.

Einstein is bored, so he suggests, “Let’s play hide-and-seek. I’ll be it!”

The others agree, so Einstein begins counting. “One… Two… Three…”

Pascal runs off right away to find a place to hide.

But Newton merely takes out a piece of chalk and draws a mid-sized square. He finishes and steps into the square just as Einstein shouts, “Ready or not — here I come!”

Einstein looks up and immediately spots Newton standing right in front of him. He says, “I found you, Newton!”

Newton replies, “No, you found one Newton per square meter — You found Pascal!”

(Hint, look up the definition of a Pascal on Wikipedia 😉 )
