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?

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
