Physical theory of dynamics

motions: up, down, around

essences: earth, water, air, fire, ether

simple vs. compound

circular motion: complete, unchanging

We have a comprehensive theory, a framework for questions.

Applications:

Comets: clearly changeable, must be meteorological

Planets: compound circular motion

Also made cogent arguments about the spherical shape of Earth

Ancient Astronomy Aristotle (384-322 BC)
