Friday, October 26, 2012: 8:00 AM-9:00 AM
Capital Room 3 (Marriott)
Lead Speaker:
Don Barry


We tell the tale of Thales measuring the height of the pyramids, but he could not have done it in the way we say. We'll consider ways by which he could have measured their height. The Egyptians had a formula for the area of a circle. We'll look at the history of attempts to explain how the Egyptians developed their method.
