Don't you just get fed up with clever bastards, these academics that talk about the way the pyramids where built, some bloke on the Melvin Bragg show this morning saying how the Egyptians squared the pyramids using the 3 4 5 method, which is fine but using a piece of rope with knots in, well that pushing the boundary's a bit too far, another program showed great feats of Egyptian engineering using a wooden 2 ft square and some string lines another one was leveling the huge blocks with A frame and plumb bob ,a good bit of reliable kit that never goes wrong but can you imagine the accumulative error on the side of a pyramid, even using my best bubble it is impossible, I don't think we are really giving enough credit to the Egyptian engineers they were obviously seriously good ,if they came back from the dead and talked to some of these Egyptologists, I think they would be insulted ,I know iv'e gone on a bit but I had to get it of my sarcophagus
