Paradoks zeno indik achilles lan penyu kagambarin sifat kontra-intuitif saking jumlah sane nenten kabatasin puniki. Achilles nguberin aukud penyu, nanging dugas ia nincap posisi penyu ring awal balapan, penyu sampun nincap posisi kalih, dugas ia nincapang posisi kalih puniki, penyu wenten ring posisi katiga, lan selanturnyane.
Zeno's paradox of Achilles and the tortoise illustrates this counterintuitive property of infinite sums: Achilles runs after a tortoise, but when he reaches the position of the tortoise at the beginning of the race, the tortoise has reached a second position; when he reaches this second position, the tortoise is at a third position, and so on.
