WBUR

Untold histories, unsolved mysteries, and other jaw-dropping stories online and IRL. Hosted by Ben Brock Johnson & Amory Sivertson.

Endless Thread

Get out your graphing calculators, because today's episode of Endless Thread is about a math problem.

Specifically: wt(π1, . . . , πm) = m−1 ∑ i=1 wt(πi , πi+1)

Now, pencils down. Stumped? So were mathematicians for decades. That is, until the equation was solved in a thread on 4Chan about watching the anime The Melancholy of Haruhi Suzumiya.

The Haruhi problem

Mo lives in Aden, an ancient city in southern Yemen. Built on a volcanic crater, it has castles and beaches set against mountains. It's beautiful. Like the rest of the country, it is also in the midst of an ongoing civil war. This summer, protests broke out over living conditions and basic services in the city -- like electricity, which can be shut off for 18 hours at a time.

But despite these conditions, for the last five years, Mo has been fighting for a persistent dream of his –– a video game internet cafe for his neighborhood. This week on Endless Thread Ben and Amory tell the story of how Mo, against all odds, has kept the lights on (quite literally) at his gaming cafe thanks to his persistence, and the help of internet strangers across the world.

Keeping the Lights on at a Video Game Cafe in Southern Yemen

Ben can make a roaring, rumbling sound with his ears that no one else can hear. He never thought much about it — whether only he could do this, or whether everyone could do this — until he discovered a subreddit called Ear Rumblers Assemble: a whole community devoted to the mysterious and understudied ability to voluntarily tense one of the miniscule muscles in our ears. 

We go into Ben's ear with Dr. Anand Devaiah, and raise questions about how everyone experiences the world differently and the enduring mysteries of the human body.

Ear rumblers assemble!

This episode was originally published on March 10, 2023. 

In 2022, freshmen at the University of North Carolina at Chapel Hill got a new neighbor: an owl. What wasn't clear was whether the owl was trying to befriend them, or catch them.

Sometimes the owl seemed to be chasing students. Other times, it seemed to come in peace. A popular campus Instagram account reported that a woman had actually raised the owl herself. After she was spotted feeding it, the owl sightings stopped, much to the disappointment of students who'd come to consider it as a sort of mascot. Where had the owl come from, and where did it go?

Endless Thread host Ben Brock Johnson and producer Grace Tatter talk about how the owl gained online campus fame, and get a surprise update from the person who knows the owl best.

Encore: Owl pursuits

Grab your telescopes because this week on Endless Thread Ben and NPR Short Wave host Emily Kwong take us down two science-related internet wormholes. First, Emily introduces us to the intergalactic world of astronaut fan fiction, starring the crew of the 2026 Artemis II moon mission. Then, Ben takes us through the r/Science discourse on a new LiDAR (Light Detection and Ranging) study mapping an ancient Amazonian civilization.

Emily Kwong takes us to science camp

The 190 passengers of a United Airlines flight from Newark, New Jersey to Palma de Mallorca, Spain had settled into their seats for their overnight flight when the captain gave an announcement: everyone had to turn off their Bluetooth devices — or he was going to turn around the plane. This confounded passengers, because Bluetooth is safe for airplanes. It stays enabled when devices are on airplane mode. United even encourages using Bluetooth headphones to connect to in-flight entertainment.

What was going on? The flight crew couldn't say. So the passengers took to...where else? Reddit.

'Turn Bluetooth off, or we're turning around.'

The brand Fruit of the Loom is almost ubiquitous in the world of underwear and casual wear. You have likely seen its logo, if not on your own body, on store racks or at least in ads. Now, in your mind's eye, picture it. What do you see?

For years, countless people have been taking to the internet to share their memory of the Fruit of the Loom logo. A lot of them have the same memory – a basket, rather, a cornucopia of fruit.

But they're all wrong. At least, Fruit of the Loom claims that is has never had a cornucopia in its logo and there is little concrete evidence to suggest that the brand is lying. So what could be behind this collective misremembering?

This week on Endless Thread, Ben and Amory embark on a quest for answers: Is the Fruit of the Loom cornucopia simply an example of the Mandela Effect (a pervasive mass-misremembering of a fact or event), or has someone pulled the woolen underwear over our eyes?

Fruit of the Loom: Horn of Lies

This week on Endless Thread it's a producer takeover with Grace Tatter and Kalyani Saxena serving up some delicious online stories. First, Kalyani digs into why the internet is so hungry for perpetual stews (a stew that is simmered and added on to in perpetuity). Then, Grace dishes on a listener conundrum about whether salty Reddit posts are worse for us than sweet ones.

The internet is a perpetual stew

Long before TikTok dances, there was the Dougie.

In 2010, Cali Swag District’s “Teach Me How to Dougie” went worldwide, and for the decade-plus since, people have been trying to learn the viral moves.

More than 15 years later, a Korean TikTok creator went viral for doing the Dougie… badly. He claimed to be learning how to do the Dougie day-by-day – but his moves were so stiff and awkward, viewers from around the world – including Endless Thread producer Kalyani Saxena — were suspicious. Was @JBStarMax faking being bad at the Dougie? Kalyani presents her investigation to Ben and Amory.

Teach us how to Dougie

Kurt Gödel was a genius mathematician and logician, considered by many scholars to be as influential as Aristotle. He was also buddies with fellow geniuses Albert Einstein and Oskar Morgenstern, the co-creator of Game Theory.

In 1947, Gödel told Morgenstern and Einstein he had identified an inner contradiction in the U.S. Constitution while studying for his citizenship test: the type of loophole that could plunge the United States into a dictatorship not unlike the Nazi regime Gödel had escaped when he immigrated from Austria.

So, what was the loophole? Over the years, everyone from Constitutional law scholars to laypeople on Reddit have wondered. Endless Thread plumbs the depths of Gödel's galaxy brain with the help of philosopher, writer and Gödel expert Rebecca Newberger Goldstein — and learns some surprising lessons about artificial intelligence, a German shorthand called Gabelsberger, and democracy along the way.
