Introduction

Imagine you're standing at the base line of a tennis court and it's time to change sides. You set off undertaking a journey of almost 24 meters, the length of a regulation court. This thought experiment, obviously without the tennis court, was invented by a man named zeno of elea in the early fifth century b c. He was the associate and student of parmenides we looked at last week, along with melissus of samos. To get to any point, you will need to travel half way to that point and halfway to that half way point, and so on.
