Lewis Dartnell is an astro-biologist, Professor of Science Communication at the University of Westminster and the author of The Knowledge: How to Rebuild Our World from Scratch. His research is on whether microbial life could survive the radiation on Mars. His books are about something closer to home: how little any of us understand about the world we depend on.Lewis and I run the thought experiment properly. If you woke up tomorrow and civilisation had gone, what kills you first, where do you go, how long does a supermarket actually keep you alive and how many people do you need before you can rebuild anything at all? The answer to one of those is 55 years and it is not the one you expect.- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -TIMESTAMPS:00:00:00 - The Big Red Reset Button00:04:26 - Get Out Of The Cities00:08:14 - A Supermarket Keeps You Alive 55 Years00:09:48 - You Need 10,000 People00:13:21 - We Outsourced All The Handiwork00:17:45 - You Have To Preserve Everything00:19:19 - Every Technology Is A Weapon00:23:14 - The One Thing He Would Take00:25:41 - Mechanical AI00:28:35 - Resilient And Fragile At The Same Time00:32:38 - We Invent Because We Are Lazy00:34:05 - The Gasifier Stove00:37:57 - The Cars That Ran On Wood00:42:03 - Making Glass From A Bag Of Sand00:51:38 - He Made His Own Photograph00:55:43 - Printing A Page From Scratch00:59:47 - The Kindle Apocalypse Plan01:05:39 - Could We Actually Live On Mars?01:11:48 - The Radiation Problem01:19:02 - The Next Book- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -CONTACT PETE› Website – http://petermccormack.com› Feedback – https://www.petermccormack.com/contact› Email – me@petermccormack.com› Instagram – https://www.instagram.com/mccormack555/› X/Twitter – https://x.com/petermccormack/CONNECT WITH LEWIS DARTNELL› Website – https://lewisdartnell.com/› The Knowledge – https://the-knowledge.org/› X/Twitter – https://x.com/Lewis_DartnellSPONSORS› IREN – https://www.iren.com/› Quo – https://quo.com/pete› Arch Public – https://archpublic.com/peter- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -LISTEN / SUBSCRIBE› Apple Podcasts: https://apple.co/40ruY9K› Spotify: https://spoti.fi/3Wc94Vu› Fountain: https://bit.ly/FountainPM› YouTube: https://bit.ly/YouTube_PM› Rumble: https://bit.ly/RumblePMFILMED BY CURTIS TAYLOR› https://www.curttaylor.co.uk/› https://x.com/curttayloruk/EDITED BY CONOR MCCORMACK› https://x.com/ConorM04- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Hosted on Acast.
