Books on the mathematics of pyramids tend to provoke sighs of resignation from Egyptologists. Not only are they often filled with impenetrable jargon and equantions, but also they tend to be based on deeply-felt underlying beliefs in alien contact or conspiracy. As Sally Katary writes in the introduction, this is not one of those books, but an interesting exploration into the way in which the whole Egyptian pyramid complexes at sites like Giza and Dahshur were tied into plans stretching over generations of pharaohs, and linking in waterworks, roads and drainage ditches, as well as the monuments themselves.
