Synopsis：Almost every high school graduate recalls the Pythagorean Theorem, a basis of geometry so fundamental that almost everything else seems to follow from it. It is so engrained in students' minds, that years after graduation they can still cite its famous formula from memory: a² + b² = c². Some can even remember how it's applied, which is a good thing, for the Pythagorean theorem is not just an interesting piece of mathematical trivia rather, it is in many ways a foundation for civilization as we know it. This innovative documentary series, The Legacy of Pythagoras, takes the viewer on a tour of the ancient world especially the Greek Isles and Egypt to witness up close how this deceptively simple equation became a building block as important as any stone or tool.
