It so happened that once all the top scientists of the world decided to play Hide-n-seek. Famous scientists like Newton, Einstein, Coppernicus, Homi Bhabha, and many others were also present. It was decided that Einstein would be the seeker..........
                   He went ahead and closed his eyes and started counting till 100. Newton could not find a place to hide so he drew a square of length 1 metre right behind Einstein, and stood inside. Eventually when Einstein finished counting, he opened his eyes and spotted Newton at once and said, "Ha..ha..NEWTON STOP!!".....
   On this Newton smirked and said that Einstein was wrong.Newton said that he was not "NEWTON"....
This left everyone baffled.....dumbstruck as he was Einstein told Newton to prove himself. On this Newton said that since he was in a geometrical square, area of which measured upto 1 metre square. So he basically was Newton per metre square.....hence he proved that he was not Newton indeed  but PASCAL.
