Marcell Fóti is an ancient mysteries researcher who is trying to figure out how the ancient Egyptians and other cultures were able to carve stones with sub-millimeter precision with relatively primitive bronze tools. Fóti’s experiments with geopolymers - ceramic polymers that can easily be mistaken for natural stone - have led him to the conclusion that the inexplicable stonework of the ancient world doesn’t have to remain a mystery. We talk to him about Natron Theory, the five part explanation for how Egyptians made their false stones, the role that natural salt deposits play in the development of a stone-making civilization, evidence that precise stonework and natron are correlated around the world, and the open questions about the ancient stone makers that remain.

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: https://anchor.fm/s/2be66934/podcast/rss - Donate: https://bit.ly/3wkPqaD - Swag: https://bit.ly/2PXdC2y SOCIAL: - Discord: https://discord.gg/MJzKT8CQub - Facebook: https://www.facebook.com/groups/DemystifySci - Instagram: https://www.instagram.com/DemystifySci/ - Twitter: https://twitter.com/DemystifySci MUSIC: -Shilo Delay: https://g.co/kgs/oty671
