Dr. Michel Barsoum is a materials scientist at Drexel University
who is the champion of a controversial theory about the great
pyramids of Giza, which says the pyramids were not fully carved
from natural stone, but were cast from a geopolymer concrete
mixture. For decades, Egyptologists have dismissed the notion
that the pyramids incorporated any human-made cement-like
materials. But Barsoum's team at Drexel University has uncovered
startling new evidence from advanced microscopy analysis of
pyramid samples. We talk to him about becoming entranced with the
deep history of Egypt, the process of determining the true nature
of a stone, and the open questions about this lost civilization
that keep him up at night. What if these discoveries are enough
to reshape our understanding of just how advanced and ingenious
the ancient Egyptian builders were? Sign up for a yearly Patreon

https://bit.ly/3v3kz2S PODCAST INFO: Anastasia completed her PhD
studying bioelectricity at Columbia University. When not talking
to brilliant people or making movies, she spends her time
painting, reading, and guiding backcountry excursions. Shilo also
did his PhD at Columbia studying the elastic properties of
molecular water. When he's not in the film studio, he's exploring
sound in music. They are both freelance professors at various
universities. - Blog: http://DemystifySci.com/blog - RSS:
