But pyramids were made of stone not of sun-backed clay bricks (adobe)! .
Seems like a big stretch.
1. Natural polymers: the author's hypothesis was that the piramids were not built with large 'massive' blocks of stone, but that natural polymeres were used like some kind of cement, in order to create those blocks. Thus they did not have to be carried all the way and involve that many people.
With a title and topic like that, who needs a source , etymology or reference?In his book "Technology of the Gods" Childress states that pyramid is Greek for 'fire in the center.' He gives no sources or etymology.
