    • n Achilles An argument, otherwise called ‘Achilles and the Tortoise,’ which was proposed by Zeno of Elea to prove that motion is impossible. Suppose that Achilles runs parallel to the tortoise, which is moving slowly in the same direction and is at the start some distance ahead of Achilles. The argument is that Achilles never will overtake the tortoise, because in order to do so he must first move to the point at which the tortoise started, and when he arrives there the tortoise will again be a certain distance ahead and the same condition of things will be repeated. Hence Achilles will not overtake the tortoise until he has completed or ended a series of advances which has no completion or end. The argument is absurd from both the logical and the mathematical point of view.

In science:

Assume now Achilles is just on the point 0 at the precise instant t0 .
The Aleph-zero or zero dichotomy
We will focus our attention just on the way Achilles performs such a traversal.
The Aleph-zero or zero dichotomy
For this, let fz ∗ (t) be the number of Z∗ -points Achilles has traversed at the precise instant t, being t any instant within the closed real interval [t0 , t1 ].
The Aleph-zero or zero dichotomy
In this way fz ∗ defines a clair dichotomy, the aleph-zero or zero dichotomy,27 regarding the numbers of Z∗ -points Achilles has traversed when moving rightward from -1 to 1 along the X axis.
The Aleph-zero or zero dichotomy
Accordingly, with respect to the number of the traversed Z∗ -points, Achilles can only exhibit two states: (1) State A0 : Achilles has traversed zero Z∗ -points. (2) State Aℵ0 : Achilles has traversed aleph-zero Z∗ -points.
