Zeno of Elea was a Greek philosopher who lived around 490-430 BCE. He is best known for his paradoxes, which challenge our understanding of motion and change. Zeno was a student of Parmenides, and his work aimed to support Parmenides' ideas about the nature of reality, arguing that change and plurality are illusions. Zeno's most famous paradoxes include the Achilles and the Tortoise and the Dichotomy Paradox. These thought experiments illustrate the difficulties of understanding infinity and continuity. His arguments have influenced many philosophers and mathematicians throughout history, prompting discussions about the foundations of mathematics and the nature of space and time.
