利用行動雷射掃描儀，能否解開古代的工程師如何在一世紀內發展出建造大金字塔的技術!?【透視偉大建築】

Egypt home to one of the most mysterious civilizations ever born on the banks of the River Nile five thousand years ago for thousands of years Egypt was one of the greatest nations in the world ruled by the mighty Pharaohs in life these all-powerful leaders demanded extraordinary devotion from their people and in death they demanded all inspiring structures to be built as their tombs they're constructed in many different shapes and sizes built on a scale never before seen on the planet Poland over a century of engineering failures and breakthroughs and now thousands of years later stand as a tribute to the skills of these ancient builders and king of them all the Great Pyramid at Giza fascinating experts and bewitching tourists in their droves at nearly a hundred and fifty metres high the Great Pyramid was the tallest man-made structure on the planet for nearly four thousand years the pinnacle of pyramid engineering with a vast burial chamber hidden inside but only a hundred years earlier the Egyptians were building their tombs with simple mud bricks so how did the ancient engineers arrive at the Great Pyramid within just a century there is no day when you talk about the pyramids you automatically think of this one the Great Pyramid here at Giza and just being beneath it does fill you with a sense of wonder and or it is the ultimate in ancient engineering with our technology we're able to follow this remarkable story of pyramid engineering evolution in a whole new way recent scientific breakthroughs mean we now have a device portable enough to travel the world and access these incredible places and powerful enough to explore deep inside their structural secrets the mobile laser scanner these bounced narrow pulses of light of objects to map them with incredible accuracy what's packed into this tiny box gives our experts virtual superpowers collecting over a billion measurements to form what is known as a point cloud on giving us an incredible 3d perspective the ability to pick up million ton structures and move them anywhere and use this data to take precise measurements with pinpoint accuracy to peel back time and help us unravel mysteries locked in the past but the real key to the technology is in the interpretation of this data and we're seeing it through the eyes of one of the world's best structural engineers Steve burrows a master of the modern building world Steve has created such famous structures as Beijing's Bird's Nest stadium Munich's Allianz Arena and Manchester's Etihad Stadium Steve has always wanted to explore the great engineering mysteries of the pyramids and now he's got the technology to do it people have been wondering how they were built for thousands of years and we've got to come along and give some new answers we set ourselves a pretty big house right armed with his scanning technology structural engineer Steve wants to understand how the ancient engineers honed their skills to arrive at the peak of pyramid building with the great pyramid here at Giza in just 100 years to do this he wants to examine three earlier pyramids which he thinks hold clues to this engineering revolution starting with the step pyramid the very first the Egyptians built followed by the mysterious collapsed pyramid and finally investigating the unusual shape of the bent pyramid to aid this mission Steve has brought a team from one of the world's best research centers Caitlin Stevens and Malcolm Williamson from the Center for Advanced spatial technologies at the University of Arkansas the team's quest starts 27 kilometres south of the capital Cairo at the Step Pyramid at Saqqara in the desert to the west of the Nile it's the world's first pyramid and the oldest large stone building on the planet containing six step levels and a rabbit's warren of subterranean tunnels and chambers it was built around 2630 BC by Pharaoh Djoser if we're going to discover the engineering process behind building a pyramid this is the place to start the step pyramid isn't as famous as the Pyramids of Giza but Steve assures me that actually it holds the key to understanding the genius of Egyptian engineering you
