The Disappearing Spoon: a science history podcast with Sam Kean
A topsy-turvy science-y history podcast by Sam Kean. I examine overlooked stories from our past: the dental superiority of hunter-gatherers, the crooked Nazis who saved thousands of American lives, the American immigrants who developed the most successful cancer screening tool in history, the sex lives of dinosaurs, and much, much more. These are charming little tales that never made the history books, but these small moments can be surprisingly powerful. These are the cases where history gets inverted, where the footnote becomes the real story.
