The Great Pyramid

The gradient of the sides of the pyramid is not determined, like sand, by its natural angle of repose. How much stone you can get, the bearing pressure that you can put on the ground and the angle determines the height of the building. This exercise in using engineering principles to augment the archaeological data may give us an insight into why the great pyramid is both the oldest and the largest pyramid of gisa. These structures are not other worldly. You don't need to come up with crazy theories to explain them. And i'm pretty sure the simple mathematics and the work between the architect, engineer and contractor gave a practical limit to what could be built.
