Zeno was a Greek philosopher who lived circa 490 to 430 BC. Zeno’s paradoxes paradoxes have puzzled us for more than 2500 years now; three of them are presented here for you to ponder upon.

**1. Achilles and the tortoise**

In a race, the quickest runner can never overtake the slowest, since the pursuer must first reach the point whence the pursued started, so that the slower must always hold a lead.

**2. Dichotomy paradox**

That which is in locomotion must arrive at the half-way stage before it arrives at the goal.

**3. Arrow paradox**
