Aristotele, Newton and Pascal were playing hide and seek and Aristotele was 'it'. So he put his hands over his eyes and strated counting to one hundred.
Pascal scurried into nearby bushes to hide but Newton just stayed and drew into the sand a square one meter a side around where he standed.
When Aristotele had counted to one hundred he looked around and spotted Newton immediately. "Your it, Newton, I found you!" yelled Aristotele.
"Not so," said Newton, "a Newton per square meter is a Pascal."
