The Western world is built on the wisdom and traditions of the ancient Greeks, who uncovered the fundamental principles that established the basics of modern technology. Explore their contributions to geometry, astronomy, and physics and take a close-up look at how they applied their knowledge: Thales predicted an eclipse, Pythagoras discovered mathematical correlation between a musical instrument's string length and its tone, Archimedes developed laws of mechanics, and a group of 90 priests made well-informed educated guesses about many things.
