Other than degrees of angle and the relationship thereof with progression of time, in context of Earth's orbital dynamics respective our host star, I confess to being unfazed by the intricacies regarding measurements or significanct numbers. Therefore, am grateful for the pool of math and the depth of variety on offer here.
I do however grasp the intricacies relating to 'the message of Giza'. Beyond that, I see little purpose in subjection the 'memo' itself to forensic analysis - the patch of sand in which it is written... does not provide instructions for manufacture.
