The Antikythera Mechanism -- a device from ancient Greece dated between 150-100 B.C.E. -- has been examined with modern imaging technology and, according to researchers, the device shows "an unexpected degree of technical sophistication for the period."According to a report in today's NY Times, the Antikythera Mechanism was probably used to prepare calendars for agricultural cycles and for determining religious festivals. "Historians of technology think the instrument is technically more complex than any known device for at least a millennium afterward."

Now can someone explain how the Egyptians built the pyramids?
