Architect Claims to Solve Pyramid Secret
Alreadybutnotyet writes "A French architect claimed Friday to have uncovered the mystery about how Egypt's Great Pyramid of Khufu was built — with use of a spiral ramp to hoist huge stone blocks into place. The construction of the Great Pyramid 4,500 years ago by Khufu, a ruler also known as Cheops, has long befuddled scientists as to how its 3 million stone blocks weighing 2.5 tons each were lifted into place. 'The most widespread theory had been that an outer ramp had been used by the Egyptians, who left few traces to help archeologists and other scientists decode the secret to the construction. Houdin said he had taken into account the copper and stone tools available at the time, the granite and limestone blocks, the location of the pyramid and the strength and knowledge of the workers.'"
If you go to the site, you'll see where he debunks previous ideas. One of those ideas is an *external* spiral ramp. But it would be twice the volume (I think...watch the movie for the exact multiplier) of the pyramid itself, which is infeasible for a 20 year project and harder to leave no evidence of after dismantling.
This guy's internal spiral ramp theory uses known tunnels that allow the pyramid to be built inside out while helping to keep laborers out of the sun.
He doesn't simply CGI all of this. He computer models it with physics to show how it could have been done with materials present for the time, and a reasonable workforce size, inside of 20 years.

As an archaeologist I have read a number of serious academic articles about the use of 3D reconstructions to present ideas. I won't get into all the gory details of archaeological theory here, but the short version is this:
Images serve as extremely persuasive representations of the past, and it often the case that a reasonably compelling image which doesn't clash do badly with out own pre-conceived notions will often be accepted without being questioned very much. A good example of this is the popular image of the Neanderthals as stooped brutish creatures - An image based upon work which was discredited more than 100 years ago (I forget the exact date). CG images can be even more persuasive due to their ability to move around and show people and systems in action.
I appreciate that this project is based upon actual engineering work, and isn't just a bunch of pretty pictures, however watching the presentation I can't help but feel that they are a little bit in love with their own images. They claim to be certain that their 'internal ramp' hypothesis is correct, and twice claim it is backed up by strong evidence, and yet they present no physical evidence whatsoever. All they have is a model which doesn't disprove their theory and a pretty 3D model. It is interesting study to be sure, but until they find physical evidence (and to be fair they have expressed an interest in looking for some) statements like 'This revolutionary idea sweeps away all the other hypotheses put forward up to now' (page 4 of the pdf) go much to far.
