The Greeks made major contributions to math and science. We owe our basic ideas about geometry and the concept of mathematical proofs to ancient Greek mathematicians such as Pythagoras, Euclid, and Archimedes. Some of the first astronomical models were developed by Ancient Greeks trying to describe planetary movement, the Earth’s axis, and the heliocentric system—a model that places the Sun at the center of the solar system. Hippocrates, another ancient Greek, is the most famous physician in antiquity. He established a medical school, wrote many medical treatises, and is— because of his systematic and empirical investigation of diseases and remedies—credited with being the founder of modern medicine. The Hippocratic oath, a medical standard for doctors, is named after him. Greek philosophical culture is exemplified in the dialogues of Plato, who turned the questioning style of Socrates into written form. Aristotle, Plato's student, wrote about topics as varied as biology and drama.
