The Disappearing Spoon: a science history podcast with Sam Kean

No one in Columbus’s time believed the world was flat. So why did so many children learn this bogus “fact” in school? It all goes back to Rip van Winkle... Advertising Inquiries: https://redcircle.com/brands

When the Mona Lisa was stolen from the Louvre, the two most scientific detectives in the world took on the case. But they overlooked the real enemy—their own petty prejudice. Advertising Inquiries: https://redcircle.com/brands

The Smyth Report is the strangest book ever written on atomic bombs—as well as highly effective science propaganda, warping our view of everything from the Manhattan Project to Robert Oppenheimer. Advertising Inquiries: https://redcircle.com/brands

When a British sub sank with all hands, JBS Haldane volunteered to investigate by experimenting on himself—even if it meant losing his own life in the process. (Part 2 of 2.) Advertising Inquiries: https://redcircle.com/brands

There’s only one thing Dr. John Haldane loved more than running dangerous experiments on himself—running them on his son Jack. But the duo would revolutionize our understanding of the human body. Advertising Inquiries: https://redcircle.com/brands

When Charles Lindbergh's sister-in-law developed heart trouble, he teamed up with a Nobel-Prize-winning doctor to save her. He had no idea the dark paths his work would lead him down, including Nazi politics and eugenics... Advertising Inquiries: https://redcircle.com/brands

Exactly a century ago, teacher John Scopes was charged with the “crime” of teaching evolution. But Scopes was hardly a defiant Galileo, nobly standing up for truth. In fact, he never even taught evolution. (Really.) But despite the unseemly origins of the Monkey Trial, Scopes proved himself a genuine hero... Advertising Inquiries: https://redcircle.com/brands

Astronomer Jules Janssen was desperate to escape the siege of Paris in 1870 and observe an eclipse in Africa—work that he hoped would confirm his discovery of a brand new element in the Sun, helium. So he devised a plan to escape the city in a hot-air balloon, despite promises by the German army to shoot him as a spy if he dared try... Advertising Inquiries: https://redcircle.com/brands

In the 1970s, paramedic units were illegal in the United States. One (very bad) television show, Emergency!, set out to change that—and saved tens of thousands of lives in the process. Advertising Inquiries: https://redcircle.com/brands

The work of Richard Meinertzhagen helped convince biologists that the Forest Owlet of India had gone extinct. But after Meinertzhagen’s frauds were exposed, one biologist grew obsessed with finding out whether it just might be alive still. (Part 2 of 2) Advertising Inquiries: https://redcircle.com/brands

He was a brilliant ornithologist—and a spy so colorful that James Bond was based on him. Richard Meinertzhagen was also a liar and a thief, and perpetrated the biggest fraud in biology history. Episode below! Advertising Inquiries: https://redcircle.com/brands

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... Advertising Inquiries: https://redcircle.com/brands

The eagle that made John James Audubon famous, the Bird of Washington was nothing but an elaborate lie. Fawning biographers have suppressed this fact for years, but careful historical work has unraveled the Audubon legend, and shown that much of his life, and work, was built on deceit. (Part 2 of 2) Advertising Inquiries: https://redcircle.com/brands

After several heartbreaking setbacks, John James Audubon’s career was in ruins—until he hatched a desperate plan to win new patrons. It involved a rare American eagle, the Bird of Washington. And when the gamble paid off, it made Audubon the most famous ornithologist in history... Advertising Inquiries: https://redcircle.com/brands

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. Advertising Inquiries: https://redcircle.com/brands

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... Advertising Inquiries: https://redcircle.com/brands

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.

When Charles Dickens published Bleak House in 1852, he included a scene where one character spontaneously combusts. 🔥 🔥 🔥 Readers loved it, but one of Dickens’s good friends—a former scientist—blasted Dickens for his scientific ignorance. It ignited one of the strangest controversies in literary history. Advertising Inquiries: https://redcircle.com/brands

It was one the largest epidemics in American history: 30,000 people paralyzed over a few months in 1930. A dogged epidemiologist eventually traced the cause to adulterated bottles of an illegal liquor/medicine called “jake.” Yet the epidemic is almost completely forgotten. About the only place it survived was in blues songs... Advertising Inquiries: https://redcircle.com/brands

Asbestos was once considered a miracle substance—a wonder of the modern age, due to its role in stopping the fires that once plagued every major city. Unfortunately, it also shreds people’s lungs. Most countries were willing to live with that trade-off, until a crusading doctor named Irving Selikoff made it his life's mission to get asbestos banned.

Rickets was once a devastating disease: up to 90 percent of the children showed symptoms in some cities, including bent spines and bowed legs, and it resulted in many women dying during childbirth. The search for the cause of rickets took decades, and ended with a startling discovery—that much like plants, human beings had the ability to photosynthesize.

Leonard Darwin had a lot to live up to. He was the son of the legendary Charles, and several siblings proved to be brilliant scientists as well. But Leonard never quite measured up as a mediocre military officer and two-bit politician. In his fifties, he pronounced his life a “failure.” But in his sixties, he finally found his calling—the dark pseudoscience of eugenics, a field he embraced in part to prove that he wasn’t the failure he imagined.

A young woman in the mid-1900s couldn’t take an at-home pregnancy test. Instead, she sent a vial of urine to a clinic, where a technician would, of all things, inject it into a frog, and hormones in the urine would cause the frog to lay eggs. This frog-based test was far faster, easier, and cleaner than any pregnancy test before, and it shifted power for family planning from doctors to women themselves.

After scientists had a handle on how many chromosomes humans have, other researchers began exploring whether certain ailments might be caused by chromosomal abnormalities. To this end, a French cardiologist discovered that Down syndrome was caused by the presence of an extra chromosome in humans. But a colleague stole credit for her work, and the battle over their legacies continues to this day, in part because the colleague is on track to become a certified Catholic saint.

It seems like a simple question: how many chromosomes do human beings have? But getting an accurate count proved surprisingly hard for much of last century. In fact, virtually every textbook once cited an incorrect number, until in 1956, a fiery Indonesian scientist finally determined the true count—and had to battle his boss over who would receive credit for this legacy-making discovery.

The 1910 return of Halley’s comet was greeted with rapture around the world—at least at first. Due to irresponsible speculation by scientists about the theoretical dangers of a close encounter with a comet, many people grew terrified of Halley’s approach and took drastic measures. They fled their homes, hid out in wells or caves, even committed suicide. It’s a grave reminder of scientific communication gone very wrong. Advertising Inquiries: https://redcircle.com/brands
