A great university was founded at Alexandria, in Egypt.

From about 600 BC, a lot of Greek men spent time observing the planets and the sun and trying to figure out how astronomy worked. They must have gotten their first lessons from the Babylonians, who were very good at astronomy and also very interested in it.

By the 400’s BC, Pythagoras was interested in finding the patterns and rules in mathematics and music, and invented the idea of a mathematical proof. Although Greek women usually were not allowed to study science, Pythagoras did have some women among his students. Socrates, a little bit later, developed logical methods for deciding whether something was true or not

In the 300’s BC, Aristotle and other philosophers at the Lyceum and the Academy in Athens worked on observing plants and animals, and organizing the different kinds of plants and animals into types. Again, this is a way of creating order out of chaos.

After Aristotle, using his ideas and also ideas from Egypt and the Persians and Indians, Hippocrates and other Greek doctors wrote important medical texts that were used for hundreds of years.

Scientists and philosophers (all men) visited back and forth between India and Greece.

The combination of the knowledge of West Asia and India with that of the Greeks led to great achievements in science, in philosophy, and in art.
