Suppose that the swift Achilles is having a race with a tortoise. Since the tortoise is much slower, she gets a head start. When the tortoise has reached a given point a, Achilles starts. But by the time Achilles reaches a, the tortoise has already moved beyond point a, to point b. And by the time Achilles reaches b the tortoise has already moved a little bit farther along, to point c. Since this process goes on indefinitely, Achilles can never catch up with the tortoise.

How can this be?

The reason is obvious,but I believe that the tortise has super-turtle power and can use his jet pack to fly faster than Achilles could run. Otherwise the points would never be the same because achilles would overtake the turtle and they would move at different speeds.
