Ian,

Until the building and use of the pyramids and other artifacts in Egypt has been explained within an engineering context, a cultural context cannot be established. Within the framework established by orthodox researchers, this has not been accomplished. They have failed to explain the engineering context, instead relying mainly on a cultural context. This, in my opinion, is putting the cart before the horse.

While attempts have been made to replicate the methods used by the Egyptians in cutting stone and building their pyramids, they have fallen short of explaining, or even attempting to explain, the more difficult aspects of the work. It is all very well to wrest a 2 ton block of limestone up a ramp to a height of 20 feet, but this effort does not explain the 100 ton granite boxes, cut to high precision, that were positioned in the rock tunnels near a dead end at the Serapeum. Nor does it explain the 70 ton granite beams above the King's Chamber or the 3 ton lintel block in the bedrock passageway in Khafre's pyramid where room for manoeuvring is limited to three people. Similarly, grinding a hole in granite using sand and a copper tube, does not explain the metrology used on many artifacts. Nor, as far as I have been able to determine, does it explain Petrie's core #7. I could go on, but I'm sure you get the idea.

With respect to the other pyramids in Egypt. I have not determined by a thorough detailed analysis a complete hypothesis explaining how each element found within them actually operated. You are wrong, however, in presuming that they are not related in some way to the fundamental technologies in the Great Pyramid.

Iterations of technologies based on fundamental principles exist all over the place. Modern power plant structures, for instance, when stripped of critical components, may have the appearance of being totally unrelated. Look, also, at the difference between the Wankel engine and a V-8. My 39-year career has led me from the manufacturing industry in England to its counterpart in America. During this time I have learned, and can tell you with confidence, that the creativity of people and their application of technologies, are not mirror images of each other.

Though the design and quality of the different pyramids in Egypt may vary, they seem to have a common denominator with respect to the tools that cut them. For instance, the corner blend radius I inspected with Starret radius gauges at the bottom of the granite box in Khafre's pyramid is 7/16 inch. This true radius is also found on the contoured block on the Giza Plateau and the alabaster platform in the pyramid enclosure at Abu Ghorab. So while these sites may have revealed artifacts that, within a cultural context separate them chronologically, there is evidence to suggest that, at least, the tools used to create the artifacts were of similar design. Could it be that the evidence we are relying on is extrinsic to the actual age of these sites?

And this brings me to my position which you had difficulty understanding in my book. Perhaps I did not articulate it as clearly as I could have. Because I believe that the engineering context takes precedence over the cultural context, it also takes precedence over chronological considerations. Performing my analysis, it didn't matter to me whether the pyramids were built yesterday, 10,000 years ago, or 50,000 years ago. What mattered to me was, how do we explain the methods that were used to build the pyramids and other artifacts in Egypt, and to what end were these artifacts created? These questions I addressed from an engineer's perspective. Peer review from fellow engineers and craftsmen have provided overwhelming support for the conclusion I have reached. But there is more research and work to be done, which brings me to your comment:

"I trust we will not have to wait another six months to clear this up?"

My first inclination upon reading this was to ignore you again for another six months. Letters that stimulate cooperation rather than animosity do not contain sarcastic comments such as this. If you are willing to listen and learn, my advice to you is to calm down, chill out and have a beer. We are not in an auto race, and I am not as impatient as you for complete answers to the other pyramids. It took me 21 years to bring The Giza Power Plant to its current state of completion. These things take time and cannot be rushed off in a 6-month period. Be confident in your own convictions as I am in mine. I'm not trying to change your perspective on Giza, and you haven't produced anything to date that would remotely change mine.

Best, Chris
