Raising an Obelisk: An Engineering Puzzle
In this NOVA video, two teams test out two theories put forth by archaeologists to explain how ancient Egyptians might have raised massive obelisks to stable, upright positions. While only one plan works in practice, both attempts demonstrate that difficult challenges require careful planning. This video is available in both English and Spanish audio, along with corresponding closed captions.
