Imitation Nation 16.01.2024

Fake cities. Imitation nations. People role-playing as civilians, spies, or enemies, complete with costumes and props. It's all part of an effort coordinated and constructed by the U.S. military to prepare soldiers for war. Fake villages designed for training purposes dot the entire United States, not to mention other countries. Researchers have identified over 400 of them around the world. Imitat...

Another Visit from the Three Santas of Slovenia 26.12.2023

We're revisiting this Christmas classic from 2021. Happy Holidays! Slovenia is a small country in Central Europe nestled between Italy, Austria, Croatia and Hungary. It's a land of snowy white peaks, green valleys, and turquoise rivers. The country is beautiful in all seasons, but it is perhaps at its most magical around Christmastime. This nation of just over 2 million people is visited by, not o...

Mini-Stories: Volume 17 20.12.2023

It's the most wonderful time of the year. It's mini-stories season! Gather the kids around the fire because We have a year-end mix of short stories about a rogue architect, spooky kitchens, a hundred year old music streaming service, and the crazy way the French tried to make telling time less crazy. Today's episode featured a story from Sound Detectives . Listen to Sound Detectives on Apple Podca...

Empire of the Sum 13.12.2023

Keeping track of numbers has always been part of what makes us human. So at some point along the way, we created a tool to help us keep count, and then we gave that tool a name. We called it: a calculator. But depending on what era you were born in, and maybe even what country, what constituted a 'calculator' varied widely. Keith Houston wrote about the evolution of the calculator in his latest bo...

Breaking Down The Power Broker (with Conan O'Brien) 05.12.2023

Today's episode features #1 Robert Caro superfan, Conan O'Brien . The Power Broker by Robert Caro is a biography of Robert Moses, who is said to have built more structures and moved more earth than anyone in human history. And he did it without ever holding elected office. Outside of New York City, Robert Moses wasn't exceptionally well known. Inside of New York, he was mostly accepted by the medi...

The Known Unknown [rebroadcast] 29.11.2023

Roman note: This is one of my favorite episodes of all time. Should be a movie. Enjoy! The tradition of the Tomb of the Unknowns goes back only about a century, but it has become one of the most solemn and reverential monuments. When President Reagan added the remains of an unknown serviceman who died in combat in Vietnam to the Tomb of the Unknowns in Arlington National Cemetery in 1984, it was t...

Long Strange Tape 22.11.2023

The Cassette tape was great in so many ways, but let’s be honest, they never really sounded great. But because the cassette was so much cheaper and easier to use and portable, a lot of people didn't care so much about the audio quality. They just wanted to be able to use something that they could carry around with them. The cassette’s other big advantage: it was easy to record on. We talked to Mar...

Home on the Range 15.11.2023

In a lot of ways, Lincoln Heights, Ohio, sounds just like any other suburb. If you walk around town, you’ll hear kids playing outside the local elementary school. You’ll hear the highway that takes commuters down to Cincinnati. At the woods on the edge of town, the birdsong is delightful. The town feels calm and peaceful - at least, until the gunfire starts. Most weekdays, it begins in the morning...

The Six-Week Cure 07.11.2023

In the mid-1900s, people flocked to Reno, Nevada -- not for frontier gold or loose slots, but to get out of bad marriages. The city became known as the "Divorce Capital of the World." For much of modern history, it has been relatively easy to get married, and extremely difficult to get divorced -- and for a time, this was true in the New World as well. But Reno provided the cure: The Six-Week Cure...

The Fever Tree Hunt 31.10.2023

Most heists target gold, jewels or cash. This one targeted illegal seeds. As the British established their sprawling empire across the subcontinent and beyond, they encountered a formidable adversary — malaria. There was a cure — the bark of the Andean cinchona tree. The only problem? The Dutch and the French were also looking to corner the market in cinchona. And the trees themselves were under t...

Model Village 24.10.2023

For decades, society has dealt with people with dementia and other forms of cognitive decline by storing them away in unstimulating, medicalized environments. But around the world, a new architectural movement is starting to challenge that old paradigm. Designing environments where people with dementia can live as normally as possible, until the very end. Model Village   Subscribe to SiriusXM Podc...

Devolutionary Redesign 17.10.2023

It’s hard to overstate just how important record album art was to music in the days before people downloaded everything. Visuals were a key part of one's experience with a record or tape or CD. The design of the album cover created a first impression of what was to come. Album art was certainly important to reporter Sean Cole, one particular album by one particular band: Devo. This is the story of...

You Ain’t Nothin But a Postmark 10.10.2023

Over a decade after Elvis Presley’s death, the king of rock & roll took over headlines once again as Americans weighed in on which portrait of Elvis would be forever immortalized on a 29 cent US postage stamp. It was put to a popular vote: should the stamp feature an image of young Elvis at the start of his rise, or an older Elvis in his iconic white jumpsuit. The resulting Elvis stamp eventually...

The Big Dig 03.10.2023

Over its more than 40 year journey from conception to completion, Boston’s Big Dig massive infrastructure project, which rerouted the central highway in the heart of the city, encountered every hurdle imaginable: ruthless politics, engineering challenges, secretive contractors, outright fraud and even the death of one motorist. It became a kind of poster child for big government ‘boondoggles.’ But...

Devil in the Details 26.09.2023

This week we have two stories featuring the devil. An infamous "training video" teaching cops how to spot and stop "satanic crimes." And a stretch of highway with the misfortune of being officially named US Route 666.

Cautionary Tales of the Sydney Opera House 19.09.2023

The Sydney Opera House is one of the most iconic and distinctive buildings in the world. It took a relative newcomer and architectural outsider to dream it up, but the saga of making this world heritage landmark a reality is a tale for the ages: a cautionary tale. And for Cautionary Tales , I turn to the brilliant Tim Harford. I’ve been dying to hear the story of the Sydney Opera House told in thi...

Blood in the Machine 12.09.2023

Brian Merchant is a tech reporter, and he'd been covering the industry for years when he started to notice a term that kept coming up. When he wrote a story that was critical of tech, he'd be accused of being a "Luddite." Like most people, Brian knew at least vaguely what the term "Luddite" meant. But as time went on, and as Brian watched tech grow into the disruptive behemoth it is today, he star...

Whomst Among Us Let the Dogs Out AGAIN 05.09.2023

All kinds of songs get stuck in your head. Famous pop tunes from when you were a kid, album cuts you've listened to over and over again. And then there's a category of memorable songs—the ones that we all just kind of know. Songs that somehow, without anyone’s permission, sneak their way into the collective unconscious and are now just lingering there for eternity. There’s one song that best exemp...

Office Space 29.08.2023

In most big cities, there’s a housing crisis. And empty office buildings are creating a different crisis known to urbanists as a ‘doom loop.’ Converting an office into housing can solve both of these crises at once, using one piece of property. This solution just seems so obvious and elegant. But for all the hype around this idea, there are surprisingly few adaptive reuse projects actually underwa...

Melanie Speaks 22.08.2023

The story of a voice training VHS tape that helped trans women at a time when other resources were hard to access. The way a person's voice changes over time feels like a simple, and overlooked act of magic. Whether intentionally or subconsciously, our voices are products of our environments as much as they are part of us. Today we’re featuring an episode about voices from a series called Sounds G...

Cooking with Gas 01.08.2023

Back in January, Bloomberg News published a story quoting an obscure government official named Richard Trumka Jr. He works with the Consumer Product Safety Commission, which regulates stuff like furniture and electronics and household appliances. Basically, the agency is supposed to make sure that the stuff we buy is safe, and won't kill us or make us sick. The Bloomberg story talked about how a g...
