Imagine this: invisible robbers break into a bank and steal massive sacks of cash, but instead of running away with it they set their haul on the front stoop of the bank in a glass case. Everyone can see the money, but only the robbers can get to it. That’s how IRS Special Agent Chris Janczewski describes the 2016 Bitfinex heist – when mystery hackers made out with over $70 million in Bitcoin. By 2020, their loot had ballooned to over $4 billion. With only digital footprints to follow,...

They carried torches and marched at night. Their goal: defend free speech in America. What started as a small group of young men demonstrating during the 1860 election, snowballed into a mass movement of working-class Americans marching to end slavery. They called themselves the Wide Awakes. And they’re widely seen as the political force that helped elect Abraham Lincoln and spur the Civil War. So why has their story gone untold? And why is now the time to tell it?   Guests:  Jon Grinspan,...

Imagine Jaws without the sneaking tuba. Or Psycho without the shrieking violins. Music can help a horror film strike fear in the heart of theatergoers. And you can trace some of these musical scare tactics back to the era of SILENT films — when organists made up film scores on-the-spot.  To celebrate the spooky season this year, we're slashing apart a 1917 silent horror film with composer Andrew Earle Simpson to find out how music can be the beating heart of suspense. Grab your popcorn and...

In the Lord of the Rings trilogy, Frodo becomes invisible when he puts the Ring on his finger. Well, at banks in the 1970s, this is basically what happened when a woman put a wedding ring on her finger. Her credit cards would no longer work, and the banks wouldn't count her income as part of the household income.  This led to a fight for women's financial independence that gave rise to the landmark Equal Credit Opportunity Act (or ECOA) and the creation of the first women's banks.  In honor...

During the mid-1800s, one third of all paper money in America was thought to be fake. It was the golden age of counterfeiting, and one exceptionally talented con artist stood out from all the rest. His fakes were nearly perfect…but for a trademark tell. Known to law enforcement only as “Jim the Penman,” this celebrity criminal led many Americans to wonder: can great art truly be criminal?  Guests Ellen Feingold, curator of the National Numismatic Collection at the Smithsonian’s National...

Sidedoor returns for its eleventh season on Wednesday, September 18th! 

Within just a few years, artificial intelligence systems that sometimes seem to display almost human characteristics have gone from science fiction to apps on your phone. But there’s another AI-influenced frontier that is developing rapidly and remains untamed: robotics. Can the technologies that have helped computers get smarter now bring similar improvements to the robots that will work alongside us? In this episode of The Joy of Why podcast, Daniela Rus, a pioneering roboticist at the...

There aren’t many portrait artists who get recognized on the street, but it happens to Devon Rodriguez all the time.

In the twentieth century, the jetpack became synonymous with the idea of a ‘futuristic society.’ Appearing in cartoons and magazines, it felt like a matter of time before people could ride a jetpack to work. But jetpacks never became a mainstream technology, leaving many to wonder…why? In this episode of 99 Percent Invisible, producer Chris Berube travels to the Udvar-Hazy Center of the Smithsonian’s National Air and Space Museum to find out for himself.This episode was produced by Chris...

It’s been called ‘the most noble and absurd undertaking ever attempted by any state.’ During the height of the Great Depression, the U.S government hired out-of-work writers and laid-off reporters and sent them out to record the stories of all kinds of Americans. Called the Federal Writers’ Project, historians have called the program a giant “listening project.”While on our summer break, we’re sharing the first episode of a new podcast series called The People’s Recorder. Host Chris Haley...

For thousands of years, fluffy white dogs could be found across the Pacific Northwest. Their exceptionally soft, crimpy hair was shorn like sheep’s wool, spun into yarn, and woven into blankets and robes by indigenous women who carefully tended them in communities across Coast Salish territory. But a hundred years ago, the woolly dog quietly vanished. Why? Today, the only known pelt of this extinct breed is in the collections of the Smithsonian’s National Museum of Natural History, and it...

Black holes could unlock the mysteries of creation and live at the heart of nearly every galaxy. But these invisible balls of extremely dense matter have never been fully understood, especially when they were only a theory. We travel through a cosmic wormhole back to the 1930s to learn how the first astrophysicist to successfully theorize a black hole, Subrahmanyan Chandrasekhar, was ridiculed and rejected by his scientific community.This is the first episode of a two-part journey celebrating...

The cicadas are back for some fun in the sun, and this time, they’re louder than ever! For the first time since 1803, Broods XIII and XIX will be emerging at the same time, covering the American South and Midwest with trillions of cicadas.

"God in a cup." "Perfection." "The world's best coffee." Panamanian geisha coffee has been called many things, but never Smithsonian Bird Friendly certified.

Join us for this fully caffeinated romp through Panama’s coffee farms as we learn all about the birds and the beans.  Guests:  Ruth...

If you’ve bought a plane ticket recently, you’ve probably had the option to pay a few extra dollars to offset your carbon emissions. That money might go toward planting some trees… but how many trees? Researchers at the Smithsonian Tropical Research Institute are trying to answer this very question by hand-measuring trees, weighing wood, and climbing to the top of the canopy. We tag along to see how carbon is measured, and why so much ends up in tropical forests.   Guests: Joshua Tewksbury,...

It started as a rumor in the cafeteria of the Smithsonian Tropical Research Institute in Panama: monkeys on an island in the Pacific were doing something no one had ever seen them do before. But when researchers went searching for these elusive capuchin monkeys, they discovered more questions than answers. Guests: Claudio Monteza, Smithsonian Tropical Research Institute fellow and researcher at the Max Planck Institute of Animal Behavior Brendan Barrett, researcher at the University of...

Money is power. But who's on our money - or isn’t - can be just as powerful. While Lady Liberty has graced American coins and dollars for most of our history, it wasn’t until the 1970s that a real woman appeared on a circulating American coin. But that's about to change. Congress recently authorized the creation of twenty new quarters featuring American women from history. But how do we decide whose likeness gets engraved in our national story? And who makes these decisions? We’ll follow the...
