In fact I bet they understood their resources and products better than most present engineers who take the immense wealth of knowledge available at their fingertips for granted.

I'm in error, the better example would be the Collapsed Pyramid.



The original construction consisted of battered, contiguous columns (built on solid bedrock). Then someone decided to convert it from a stepped pyramid to a flat-sided pyramid by adding onto a foundation of sand. Probably bureaucrats.

Also, it now appears that the Babylonians used the principle of area under a curve, a basic tenet of the Calculus.

This Babylonian Astronomy Text Changes History.

OTOH the pyramids sure could use a 4% radius on their edges.
