Plato was a great Greek philosopher. His teacher was named Socrates. Socrates was also a philosopher. Plato owned an academy and called it Plato’s academy. His most famous work was called The Republic.
Archimedes was the most famous Greek scientist and mathematician. Archimedes created a number system called exponents. He counted all the sand in our solar system and created pullies and levers.
There were other philosophers that thought the world was flat, or everything was made of fire, or everything was made of water. They also thought the world was a cone or the earth was at the center of the solar system. Archimedes was my most favorite person to learn about.
