^{8}For those of you that are interested in the intersection of mathematics with philosophy, you might
want to read about a Greek philosopher named Zeno and his idea that movement was impossible.[Clegg,
2003] For example, in order to walk to the store, you have to walk half the distance first. Before you get that
far, you have to walk half that distance, and before you get that far, you have to walk half that distance, and
so on and so on. If you continue with this logic, then you have to start by making an infinitely small
distance, and since 1∕∞ = 0 then you never move in the first place. This makes it difficult to buy
milk.
