Sidedoor

It’s a song we often hear at the start of the new year. But what does “auld lang syne” even mean? And how did it come to be associated with New Year's Eve? With a little musical sleuthing, we find Charlie Chaplin might have something to do with it… Guests: James Deutsch , curator of folklife and popular culture at the Smithsonian Center for Folklife and Cultural Heritage

North American River Otters are popping up in places they haven't been seen in decades and nobody really knows why. As we search for answers we discover a trail of fish heads, poop splats and cuddle parties. Guests: Katrina Lohan, head of the Coastal Disease Ecology Laboratory at the Smithsonian Environmental Research Center Alejandra Morales Picard , psychologist at Montgomery College Rebecca Stu...

When Maggie Kuhn was forced to retire from the job she loved at age 65, her colleagues gave her a sewing machine as a parting gift. Outraged, she shut the sewing machine in a closet and, instead, stitched together the first-ever movement against ageism in the U.S. The Gray Panthers would galvanize gray haired citizenry and youth alike to challenge the way Americans think about aging.  Guests : Kat...

All three Giant Pandas are leaving the Smithsonian's National Zoo for China by the end of the year. What's up with that?! We sat down with the director of the Zoo, Brandie Smith, to find out why the pandas are leaving, and whether China plans to send more. This might truly be the end of a beara ... we mean era! Guests: Brandie Smith, John and Adrienne Mars Director of the Smithsonian’s National Zo...

The Smithsonian Institution was founded on principles of reason and scientific inquiry. So why is the Smithsonian home to countless tales of unexplained phenomena and—dare we say—ghost sightings? Inspired by an apparition at the National Museum of American History, we creak across museum attic floorboards, sneak into an old house in the woods, and even travel back in time to bring you a collection...

Looks like these criminals used correct postage, 'cause justice is about to be delivered. Okay, there are no snappy one-liners in this crime scene investigation, but there are explosions, collisions, manhunts and even a cow who was in the wrong place at the wrong time. On the centennial of "The Last Great Train Robbery," we re-examine the evidence to find out how U.S. Postal Inspectors tracked dow...

Cellphones put the power of the world at our fingertips. With the touch of a finger, you can instantly connect with your doctor, have food delivered to your office or simply obliterate your niece at Words with Friends. And it's all made possible by rocks formed millions of years ago, deep underground. Join us as we bust open our devices to figure out how these stones power our phones. Guests: Josh...

Icky Gunk. Moldy Hay. Kermit. You might recognize one of these names. Before Kermit joined Miss Piggy and Big Bird, he was kicking it with Sam and Friends — a local tv show in Washington, D.C. that launched Jim Henson's career. We journey back to 1955 to figure out how this eccentric cast of puppets built the foundation for everything Jim Henson would do afterwards, from Sesame Street, to The Mupp...

Sidedoor returns for its tenth season on Wednesday, September 13th!

In 1860 the fastest way to get a message to a family member, partner, or colleague wasn’t by text but by hoof…specifically, a pony’s. In just ten short days the Pony Express delivered mail between St. Louis and Sacramento. To find out what it was like to travel this legendary trail, there’s only one way: get on a horse and follow all 2,000 miles of it. That’s what writer Will Grant did, retracing...

When a  200-year-old legal document  anonymously arrived at his office, Smithsonian Libraries and Archives conservator William Bennett assumed it would be full of boring legal jargon. Instead, he found a juicy tale of family betrayal that would forever change what we thought we knew about the founding of the Smithsonian. In honor of the Smithsonian’s 177th birthday, we’re sharing one of our favori...

When you imagine the sound of a dinosaur, you probably think of a scene from the Jurassic Park movies. How do sound designers make these extinct creatures sound so believably alive? And what does modern paleontology tell us about what dinosaurs REALLY sounded like? This guest episode of Twenty Thousand Hertz features Jurassic World sound designer Al Nelson and paleontologist Julia Clarke.   We’ll...

A Smithsonian researcher has made a discovery we couldn't wait to sink our teeth into — what might be the earliest evidence of our human ancestors eating each other. This conversation is a special update from our past episode 'Did Meat Make Us Human?' Bon appétit! 

Before the invention of photography, only the rich could afford to have portraits of themselves. But in the early 1800s, a device called the physiognotrace democratized portraiture, making it possible or everyday people to have their images captured in silhouettes. A man named William Bache traveled the United States creating hundreds of silhouette portraits with the aid of the physiognotrace, lea...

America has a long history of clustering heavy industry and toxic facilities in communities where people of color live. But in the 1980s, a series of events sparked a movement to fight back against these environmental injustices. We trace the history of the environmental justice movement from the farmlands of North Carolina to a watershed moment in the nation's capital.    Guests:    Vernice Mille...

In 1948, Moses Asch set out with an ambitious project: to document the world’s sounds! 75 years later, that project has grown into one of the world’s most eclectic, iconic and LARGEST repositories of recorded sound… from American folk music, to sounds of everyday life, and even a serenade for turkeys. Folkways Recordings —as it's now known— lives on within the Smithsonian, connecting the past, pre...

Women have long fueled America's greatest scientific achievements. But when you go searching for information about these women scientists, you'll likely come up short. Only 19% of articles on Wikipedia are about women. In the field of science, this difference is even more pronounced. But now, a team at the Smithsonian is using artificial intelligence and good old fashioned research skills to scour...

Nowhere in the world are lawns as revered as they are in the United States. The picture-perfect patch of grass is so deeply rooted in the American psyche it feels more like a default setting than a choice. Americans spend countless hours every year seeding, watering, mowing, and fertilizing patches of grass that don't make much sense, economically or ecologically. But why? In this episode, we dig...

As a kid, Bill Nye spent whole days wandering the halls of Smithsonian museums. Now the Science Guy is back… to find his own blue lab coat and periodic table bowtie on display at the National Museum of American History. We sit down with Bill Nye to get schooled on science education, comedy, and the 1990s hit TV show that turned him into an entire generation’s favorite science teacher. Guests: Bill...

Until the 1970s, women were barred from competing in U.S. marathons because of the belief that the "violent movements" would wreak havoc on their reproductive system, "thus defeating a woman’s true purpose in life, i.e., the bringing forth of strong children." Through a series of steps, stumbles —and one epic tackle— running pioneers like Roberta "Bobbi" Gibb and Kathrine Switzer blazed the trail...

We think of paintings as art, but can they also be a source of data? 300 years ago, a young prince inherited the throne in Udaipur, India, and brought with him some newfangled ideas about art. His court artists created massive paintings that flew in the face of convention, documenting real life events, times, places and even emotions —especially during the annual monsoon season. These paintings ar...

Most people in North America can't see the Milky Way. The reason? We're ensconced in a luminous fog of artificial lighting 24/7. The evolution of lighting technology over the last century has made it possible to live, work, and play at any hour - day or night. But light pollution affects all life on earth, from humans to plants and insects. So, how did we find ourselves surrounded by a glowing shr...

When Sidedoor listener Cliff Hall bought a used violin, he found a tattered note tucked alongside the century-old instrument. Obsessed with this cryptic piece of paper, Cliff’s quest to find the owner of the violin unlocked a tale of subterfuge, scandal, and the Smithsonian’s first donation of rare instruments.   Guests: Deborah Shapiro , reference archivist at the Smithsonian Institution Archives...

Sidedoor returns for its ninth season on Wednesday, March 1st!

They bring out the voyeur in us. And the Smithsonian’s Archives of American Art is full of them. In three short letters, we offer a glimpse of tender moments in the complex lives of others. Guests: Josh T. Franco , Head of Collecting at the Archives of American Art. Liza Kirwin , Interim Director of the Archives of American Art. Jenny Williams , Associate Director for Advancement at the Archives o...
