Document Summary

The fragmented geography and decentralized rule of ancient greece allowed for an intellectual freedom that led to a revolution in scientific thought. Greece are one of the few to encourage theorizing about the universe. The popularity of plato and aristotle led to nearly 2000 years of widespread belief in the geocentric model, even though the heliocentric model was also taught in their time. Geocentrism the belief that all of the celestial bodies revolve around a fixed earth (earth experiences day and night because the sun orbits the earth) Heliocentrism all the celestial bodies, including the earth, revolve around the sun (earth experiences day and night because earth spins around its own axis once a day) Geocentrism = plato, eudoxus, aristotle, apollonius, hipparchus, ptolemy. Considered the father of science for attempting to find explanations for natural phenomena that didn"t involve the gods. His philosophy gained support when he demonstrated that some acts of natures (e. g. eclipses) are predictable.
