This is a little uncompleted project I found when I was looking through 'My Stuff'. Press space to start the simulation.
The Achilles and the Tortoise paradox dates back to the ancient Greeks and was first thought of by a man named Zeno. It is usually recounted like this: "A tortoise challenged the great athlete Achilles to a race, on the condition that the tortoise be given a reasonable head start of 10 metres [here it's 100x]. Now, Achilles was a very fast runner and could cover the 10 metres head start in the same time it took the tortoise to cover 1 metre of his own. But then in the time it takes Achilles to cover that 1 metre, the tortoise has managed to cover perhaps another 10 cm. Every time Achilles tries to catch up, the tortoise has gone just a bit further. So how can Achilles ever overtake the tortoise?"
