In Section 5 we show that there exists a correspondence between the Littlewood-Ross super-task and Zeno's Achilles and the Tortoise.
While this reduction of a super-task to tasks was necessary to define the outcome of a super-task, the opposite, transforming a task into a super-task, is the core of one of the most famous paradoxes of all: Zeno's Achilles and the Tortoise, where a simple continuous movement for a finite period of time is split in an infinite number of steps.
This striking correspondence prompted us to create a mapping between a formulation of Zeno's Achilles and the Tortoise and the Littlewood-Ross super-task:
