A Little History Lesson

  1. 1. A little history lesson….
  2. 2. Meet Pythagoras……
  3. 3. A few facts about Pythagoras:  Born about 569 B.C. on the island of Samos in Greece  He traveled quite a bit with his father  Was educated by 3 great philosophers  Traveled to Egypt & was accepted into the priesthood. There he studied geometry
  4. 4. A few little know facts:  Pythagoras was taken prisoner by the King of Persia and brought to Babylon  He studied arithmetic & music with the Magoi and the mystical Babylonians  He went back to Greece, but then left for Italy  It was in Italy that he founded the Brotherhood of Pythagoreans
  5. 5. What did the Brotherhood of Pythagoreans accomplish?  They believed that reality is mathematical in nature  They observed strict loyalty and secrecy  They were interested in the abstract proof and many types of mathematical concepts  Followers discovered that the sum of the angels of a triangle is equal to 2 right angles or 180 degrees
  6. 6. But it’s not all about math….  Pythagoras was a musician as well. He learned the mathematical ratios of vibrating strings  They taught that the earth was a sphere in the center of the universe  They taught that the orbit of the moon was inclined to the equator
  7. 7. But did he really invent the Pythagorean Theorem?  Probably not. The theorem was already known by the Babylonians 1000 earlier.  The Pythagoreans were perhaps the first to prove it.  Legend has it that when they finally completed the proof, the Pythagoreans sacrificed 100 oxen. http://jwilson.coe.uga.edu/EMT668/EMAT6680.F99/Challen/pythagorean/lesson1/lesson1
