Did you Know?

- Aristotle was born in Ancient Greece over 2000 years ago (about 300 BC). Once referred to as," The man of all knowledge", Aristotle provided answers for global phenomenon that were popular for over 2000 years. He reasoned that 'heavier' objects fell to the ground faster than 'lighter' objects. Aristotle also conceived the universe consisting of celestial spheres. The stars outside of these stars act as lights for humans in the night. Aristotle was also a supporter of a geocentric model of the universe: meaning he thought the Earth was at the center of the universe. His theories of motion included all motion on the Earth to be straight and linear, whereas motion in the heavens (above the Earth) was circular. Of course with the revelations by Galileo and Newton, all of Aristotle's laws have become obsolete. He is still however respected for his many contributions to the field of philosophy.
