All the physicists are playing hide and seek. Einstein is the ‘den’ and stands against the wall with his eyes closed and counts till 100 to enable all the physicists to run and hide. At the count of 100 Einstein turns around and finds Newton standing there.
He screams, “Newton, you are out!” Newton says, “No, I ‘m not!”
Einstein says, “Yes, you are. I can see you here in front of me”.
Newton says, “I’m not out. Pascal is.”
Einstein is a bit confused and starts to scratch his head and beard.
Newton says “Here, Let me explain”
He draws a square one meter by one meter on the floor and stands in the middle of it and says,
“Newton per meter square is a Pascal, so it’s Pascal who’s out not me”
