Ok, this has go to be one of the nerdiest jokes I read lately 🙂

Archimedes, Pascal, and Newton are playing
hide-and-seek.
Archimedes covers his eyes and starts counting.
Pascal looks around and hides behind a bush.
Newton grabs a stick and scrapes a one meter by one
meter square in the dirt and stands in it. Otherwise he does not hide
at all.
Archimedes opens his eyes and looks around. Of
course, he immediately sees Newton and calls “I see Newton”
Newton calmly says “But hang on, one Newton in a
square meter is a Pascal!”
