You shoot an arrow at a tree. At some point it is half-way there. You can keep dividing the distance to the target by one-half forever. The arrow will never arrive at the tree. Wait, What??
One of my high school Math teachers explained the theory that, if the boys stood along one wall and the girls were along the other and they were instructed to move half of the distance to the other group, they would never meet but they would be close enough for all practical purposes.
