Achilles and the Tortoise (Posted on 2002-11-22) Difficulty: 3 of 5
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?

What!? The tortoise... | Comment 17 of 31 |
What?! The tortoise actually reached point a? How did he do that, since he would have had to cross 1/2 the distance to point a first... .... .... .... ....
