The Disappearing Spoon: a science history podcast with Sam Kean

Sam Kean, Bleav

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.

    Why Not Just Rename the “Hitler Beetle”?

    Taxonomy has a sadly ugly history of naming species after despicable people—even Adolf Hitler. Given the controversy these names generate, there have been many calls to drop them. But taxonomists have so far resisted most of these efforts, for reasons both good and bad...

    The Dignity of the Ig Nobel Prizes

    The Ig Nobel Prize is the bizarro cousin of the Nobel Prize—awarded for odd or unusual research “that first makes you laugh, then makes you think.” Some scientists hate them, and have refused to accept the award. But they’ve grown into a beloved institution—and one with some surprising benefits to science.

    The Nobel Disease

    Winning a Nobel Prize is a good thing—mostly. But surprisingly often, Nobel laureates go kooky and start promoting bizarre things like homeopathy, ESP, AIDS denialism, and worse. Psychologists are starting to understand why...

    Why Doctors and Scientists Embraced the Nazis

    Nazism was a society-wide catastrophe for Germany, but some professions deserve more blame than others. In particular, there was a surprisingly large percentage of doctors and engineers among the Nazis. Sociologists and historians have now worked out why.
