Plato (c.429-327 BC) - He was a brilliant student of Socrates and later carried on his work. He gathered Socrates' ideas and wrote them down in a book. Plato founded the world's first university. He wrote down his teachings and people all over the world, even today, study the Greek philosophers

Aristotle (382-322 BC) - discovered many things in science and biology. He wrote books about physics, poetry, zoology, biology, politics, governments, and more. His father was the personal physician of the King of Macedonia. When Aristotle turned 17, he went to Athens to study with Plato.

Parmenides - watched an eclipse of the Moon in about 470 BC, and noticed that the Earth's shadow was curved. He worked out that if the shadow was curved, then the Earth must be round.

Archimedes - was a mathematician and an engineer. He designed a machine, called the Archimedean screw, which could make water flow uphill. His design has been used for almost 2,000 years, to take water from rivers to the fields. Archimedes was able to tell fool's gold from real gold.
