There is a unifying Pattern that underlies much if not all of science, which manifests itself in the measures of dimension; i.e. time, distance, volume, mass, and of those measures that derive from them. This Pattern arises from a simple geometric progression, based on the numbers 2 and 3. Deus Ordiri Fundamentum-"God Begins, Lays the Order of the Foundation"-traces this Pattern through much of modern science, including: astronomy, physics, geodesy, metrology, cartography, etc., and arrives at the almost inescapable conclusion that mankind did not devise this system, since it is all too perfect; rather, it was given to him by the Creator of the cosmos. Deus Ordiri Fundamentum then proceeds to examine several world-renowned ancient monuments and documents a startling sophistication of knowledge embedded in them that embodies many of the measures from the Pattern. These monuments were specifically designed and built to memorialize much of this vast knowledge-the collected inheritance of a sophisticated civilization. Number and Geometry were central to this process. And, finally, Deus Ordiri Fundamentum examines six carved stelae in the Step Pyramid complex of Saqqara, Egypt, and finds that they hold mankind's deepest held beliefs and understandings, regarding the origins and manifestations of time and the other dimensions that are the framework of our perceived reality.
