Zeno's Brexit

The Ancient Greek philosopher Zeno articulated a series of paradoxes, one of the most famous being the ‘dichotomy’ or ‘race course’ paradox. In order to reach a destination, a runner must first reach the half-way point, but to reach that point must first get a quarter of the way there, and to do that must get an eighth of the way there, and so on. Since this generates an infinite sequence that never quite adds up to the full distance, it is impossible for the runner ever to reach the destination
