Get Off My Lawn
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 into the history of our lawnly love to learn where the concept came from...and how we grew so obsessed.
Guests:
Cindy Brown, manager of collections, education, and access at Smithsonian Gardens
Joyce Connolly, museum specialist at the Smithsonian’s Archives of American Gardens
Abeer Saha, curator of agriculture and engineering at the Smithsonian’s National Museum of American History
Sylvia Schmeichel, lead horticulturist at the Smithsonian’s National Museum of Natural History
Jeff Schneider, deputy director of Smithsonian Gardens

Bill Nye the Sidedoor Guy
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 Nye, Science Guy
This episode was produced in collaboration with the Smithsonian’s National Museum of American History. Their exhibition, Entertainment Nation, shows the power of American entertainment to captivate, inspire, and transform.

Space Marathon
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 for women marathoners who followed, including Sunita Williams — the first person to run the Boston Marathon IN SPACE!
Guests:
Sunita Williams, astronaut
Jennifer Levasseur, curator, Smithsonian's National Air and Space Museum
Peter Sagal, marathoner; host of NPR's Wait Wait ... Don't Tell Me!
Bobbi Gibb, first woman to run the Boston Marathon
Kathrine Switzer, first women to officially run the Boston Marathon

Monsoon Mood
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 are so detailed that - centuries later - they can serve as archival records to help understand our own changing climate.
Guests:
Debra Diamond, Elizabeth Moynihan Curator for South Asian and Southeast Asian Art at the Smithsonian’s National Museum of Asian Art
Dipti Khera, associate professor, Department of Art History and Institute of Fine Arts, New York University
Mark Giordano, professor of geography and vice dean for undergraduate affairs at Georgetown University’s Walsh School of Foreign Service
This episode was produced in collaboration with the Smithsonian’s National Museum of Asian Art’s exhibition: A Splendid Land: Paintings from Royal Udaipur, in celebration of the 100th anniversary of the museum’s founding and the 75th anniversary of Indian independence.
The exhibition is on view through May 14, 2023.

Lights Out
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 shroud of electricity... and can we have the dark, without giving up the light?
Guests:
Hal Wallace, curator of electricity collections at the Smithsonian’s National Museum of American History
Lisbeth Fuisz, coordinating director, Lights Out D.C.
Brian Schmidt, museum specialist, Smithsonian National Museum of Natural History
Diane Turnshek, Astronomer; Dark Skies Advocate
This episode was produced in collaboration with the Smithsonian National Museum of Natural History's exhibition: Lights Out: Recovering Our Night Sky. Through over 100 photographs, nearly 250 objects, interactive experiences, tactile models, and a theater program, discover why dark nights matter, rekindle your connection with the night sky, and consider how much light at night is enough—for whom, for what purpose, and who gets to decide?
Lights Out: Recovering Our Night Sky is open March 23, 2023 - TBA.

The Cabbage Patch Kids Riots
In 1983, the Cabbage Patch Kids were released, causing widespread pandemonium in toy stores and in the media. How did a children's toy inspire such bad adult behavior? Slate’s Decoder Ring podcast explores the strange world of the Cabbage Patch Kids to figure out why they hit it so big. The answer involves butt tattoos, slightly grotesque faces, industrial innovations, an origin story in a cabbage patch, and serious accusations of copyright theft.
