Jest for Fun
Newton or Pascal?
All the great scientists met up in heaven after they had died and decided to play a game of hide and seek.
Einstein was the one who had the den. He counted up to one hundred before he started to search for the other scientists.
Everyone started to hide except Newton who just drew a square with sides of one metre and stood in it, right in front of Einstein.
Einsteins finished counting ....97, 98, 99, 100! He opened his eyes and found Newton standing right in front of him. 
Einstein exclaimed "Newtons out, Newton's out!"
Newton said "No, I'm not out as I'm not Newton!" 
All the other scientists now left their hiding places and demanded that he proved that he was not Newton.
Newton said: "I am standing in a square of area 1 metre square. That means I am Newton per metre square. Hence I am Pascal as 1 Newton per square metre = 1 Pascal!"
