Naked Science - Pyramids

Subscribe to Naked Science - Every Wednesday we present a new video, so join us to see the truth laid bare... For over four and a half thousand years the pyramids of Egypt have stood as wonders of the world. The facts are astonishing, the Great Pyramid alone weighs almost six million tons and contains over 2.3 million stone blocks. Naked Science sets out to uncover four great mysteries that still surround the pyramids, how were they built, who built them, why were they built, and what secrets may still lie hidden within their stones. As four millennia and countless generations stand between us and the men who built the pyramids we have to study the buildings themselves to uncover the answers. With British engineer Denys Stocks we learn the art of pyramid building. Stocks has spent twenty years mastering the techniques used by the ancient workmen and shows how such vast quantities of stone were quarried, transported and fitted by a civilisation that had not even invented the wheel.
