to catch him. At least if they believe Zeno.

Zeno thought of the Achilles paradox. If a faster runner is trying to overtake a slower runner in front of him, he will first have to move to the midpoint between his position and the slower runner’s position. From there he has to reach the new midpoint between him and the one in front. And so on. He will never reach the slower runner in front. Or it can be explained like this:

“There are a series of philosophical problems known as Zeno’s paradoxes. One of them says that as you attempt to leave a room, you must first reach the midpoint between you and the exit. As you continue toward the doorway, you will again reach the new midpoint, with each successive attempt to exit the room requiring you to reach the next midpoint. The paradox is that you should be unable to leave a room because you can infinitely halve the distance to the exit without ever getting out of the room.”
