There are many walls in Belfast which physically separate Protestant neighborhoods from Catholic ones. Some are fences that you can see through, while others are made of bricks and steel. Many have clearly been reinforced over time: a cinderblock wall topped with corrugated iron, then topped with razor wire, stretching up towards the sky. Many of the walls in Northern Ireland went up in the 1970s and ‘80s at the height of what’s become known as “The Troubles.” Decades later, almost all of the walls remain standing. They cut across communities like monuments to the conflict, etched into the physical landscape. Taking them down isn’t going to be easy.

During the depths of the Depression in the late 1930s, 300 craftspeople came together for two years to build an enormous scale model of the City of San Francisco. This Works Progress Administration (WPA) project was conceived as a way of putting artists to work while also creating a planning tool for the city to imagine its future. The massive work was meant to remain on public view for all to see, but World War II broke out and the 6,000 piece, hand-carved and painted wooden model was put into storage for almost 80 years.

Farmers have known for centuries that putting a hive of honeybees in an orchard results in more blossoms becoming cherries, almonds, apples and the like.  Yet it’s only in the last 30 years that pollination services have become such an enormous part of American agriculture. Today, bees have become more livestock than wild creatures, little winged cows, that depend on humans for food and shelter.

When confronted with trash piling up on a median in front of their home in Oakland, Dan and Lu Stevenson decided to try something unusual: they would install a statue of the Buddha to watch over the place. When asked by Criminal’s Phoebe Judge why they chose this particular religious figure, Dan explained simply: “He’s neutral.” He’s Still Neutral Subscribe to Criminal on Apple Podcasts or RadioPublic Subscribe to SiriusXM Podcasts+ on Apple Podcasts to listen to ad-free new episodes and get exclusive access to bonus content.

Men are often the default subjects of design, which can have a huge impact on big and critical aspects of everyday life. Caroline Criado Perez is the author of Invisible Women: Data Bias in a World Designed for Men, a book about how data from women is ignored and how this bakes in bias and discrimination in the things we design.

Sand is so tiny and ubiquitous that it's easy to take for granted. But in his book The World in a Grain, author Vince Beiser traces the history of sand, exploring how it fundamentally shaped the world as we know it. "Sand is actually the most important solid substance on Earth," he argues. "It's the literal foundation of modern civilization." Plus, Roman talks with Kate Simonen of the Carbon Leadership Forum at the University of Washington about measuring the embodied carbon in building materials.

Reporter Andrew Leland has always loved to read. An early love of books in childhood eventually led to a job in publishing with McSweeney’s where Andrew edited essays and interviews, laid out articles, and was trained to take as much care with the look and feel of the words as he did with the expression of the ideas in the text. But as much as Andrew loves print, he has a condition that will eventually change his relationship to it pretty radically. He’s going blind. And this fact has made him deeply curious about how blind people experience literature and the long history of designing a tactile language that sometimes suffered from trying to be too universal.

When Singapore gained its independence they went on a mission to re-house the population from densely-packed thatched roof huts into giant concrete skyscrapers. In 1960, they formed the Housing and Development Board, or HDB, and just five years later they had already housed 400,000 people! In Singapore, where land is scarce, it’s not unlikely for apartment buildings to be built on top of land that was graveyards not too long ago. But building on top of a graveyard has its complications.

All over Oakland right now people are wearing Warriors shirts and flying their Warriors flags from their cars, and as much as we like our hometown team here at 99pi, we've been following these NBA finals for another design-related reason. When you watch the games in Toronto the whole stadium is filled with people wearing red raptors jerseys, but every now and then you'll see these little flashes of purple. Those bold fans are wearing one of the most polarizing jerseys in the history of sports. A jersey that we actually did a whole episode about last year. So in honor of the Toronto Raptors, and the beautifully ugly jersey they gave the world, we're gonna rerun that episode for you today, along with an update from our new 99pi team member Chris Berube, a Torontonian and Raptors fan since he was a kid.

The inside of a Horn & Hardart Automat looked like a glamorous, ornate cafeteria -- but instead of a human handing you hot food over a counter, you would push your tray up to a wall of little glass cubbies. Each cubby housed a fresh, hot portion of food on a small plate. It could be anything from a side of peas to a turkey sandwich, to a slice of pie. You simply put in some nickels, and then the door to that cubby would unlock and you could take the plate that was inside. This automated food experience has reemerged in new restaurants today. The Automat Plus, we revisit the story of when food advertising was revolutionized by motion.

Mexico City is in a water crisis. Despite rains and floods, it is running out of drinking water. To solve the scarcity issue, the city began piping water in from far away as well as from aquifer below ground, creating yet another problem: the city began to sink as the moisture was sucked up and out from below. Meanwhile, rainwater which should be replenishing the ground can’t penetrate it thanks to impermeable paved surfaces above. Uneven ground and crooked buildings reflect this subterranean crisis on the surface, misshaping the city’s infrastructure and architecture.

There are a lot of Gothic churches in Spain, but this one is different. It doesn’t look like a Gothic cathedral. It looks organic, like it was built out of bones or sand. But there’s another thing that sets it apart from your average old Gothic cathedral: it isn’t actually old. Gaudí wasn’t able to build very much of his famous church before he died in 1926. Most of it has been built in the last 40 years, and it still isn’t finished. Which means that architects have had to figure out, and still are figuring out, how Gaudí wanted the church to be built La Sagrada Familia This episode was originally broadcast in October 2017 Subscribe to SiriusXM Podcasts+ on Apple Podcasts to listen to ad-free new episodes and get exclusive access to bonus content.

Libraries get rid of books all the time. There are so many new books coming in every day and only a finite amount of library space. The practice of freeing up library space is called weeding. When the main branch of the San Francisco Public Library was damaged by an earthquake 1989, the argument over which books need to be weeded, and how they were chosen for removal, reached fever pitch. Weeding is Fundamental This episode also features “The Pack Horse Librarians Of Eastern Kentucky” produced by the Kitchen Sisters and mixed by Jim McKee.

From the 1950s right up to its collapse, people in the Soviet Union were completely infatuated with Indian cinema. India and The Soviet Union had completely different politics, languages, and cultures. But for a brief time, these two nations found they had much more in common than expected, and realized this through a love of movies.

This past fall, two hundred people gathered at The Explorer’s Club in New York City. The building was once a clubhouse for famed naturalists and explorers. Now it’s an archive of ephemera and rarities from pioneering expeditions around the globe. But this latest gathering was held to celebrate the first biological census of its kind –an effort to count all of the squirrels in New York City’s Central Park. Squirrels were purposefully introduced into our cities in the 1800s, and when their population exploded, we lost track of how many there are.

Even if you don't recognize a Noguchi table by name, you've definitely seen one. In movies or tv shows when they want to show that a lawyer or art dealer is really sophisticated, they put a Noguchi table in their waiting room. Noguchi was a world renowned sculptor and he had huge ambitions. His largest and most personal concept was a giant public sculpture that took the form of a massive pyramid. Try to Imagine a cross between a Mayan temple and a mountain. It pushes out of the earth with a long slide sloping down with steps on two of its faces. Noguchi thought of it as a playground, and he called it Play Mountain. Noguchi’s ideas - about imagination, and freedom to play - have left a deep mark on playground designers, and are continuing to shape the playgrounds all around us.
