I read stocks years back and wasn't really impressed with his methods or conclusions.
Apparently, neither was Dunn. As he pointed out in his 'Obelisk Quarry Mystery' article, using the best-case scenario from Stocks' own calculations regarding the quarrying of the 440-ton Aswan obelisk, he concluded:
"...the minimum amount of time just to quarry the stone is fifty years! It is physically impossible to assign more workers to accomplish the task in less time... We are still left with the task of finishing the product, which, in my estimation, would conservatively take another decade using the tools the Egyptologists allow the ancient Egyptians to have in their tool kit... Along with all previous considerations and claims of geometry and precision, and now using the Egyptologists' own data, this confirms that the assertions of the Egyptologists are incorrect and that the ancient Egyptians were much more advanced than what we have allowed in the past."
So much for Stocks, I guess...
