Scientists in heaven

Once all the scientists die and go to heaven............
They decide to play hide-n-seek.........
Unfortunately Einstein is the one who has the den...........
He is supposed to count up to 100...and then start searching.....
Everyone starts hiding except Newton.........
Newton just draws a square of 1 meter and stands in it right in front of Einstein...........
Einstein's counting 1,2,3......97,98,99.....100........
He opens his eyes and finds Newton standing in front........

Einstein says "newton's out..newton's....out....."
Newton denies and says i am not out........
He claims that he is not Newton......
All the scientists come out to see how he proves that he is not Newton..........
Newton says "I am standing in a square of area 1m squared..... That makes me Newton per meter squared...... since one Newton per meter squared is one Pascal, I'm Pascal, Therefore Pascal is OUT...........!
