Even if we think of the camera as a neutral technology, it is not. In the vast spectrum of human colors, photographic tools and practices tend to prioritize the lighter end of that range. One example of this bias was Kodak's Shirley Card, a reference photo used to calibrate photo printing machines.  For decades all of the models on the Shirley Cards were white. This meant that photographs of people with darker skin tones were often not printed correctly. But that's just one example of the limited dynamic range of photography purposefully excluding people with darker skin.

Born in 1872, American architect and engineer Julia Morgan designed hundreds of buildings over her prolific career, famous for her work on incredible structures like the Hearst Castle in San Simeon, California.

She was also the first woman to be admitted to the architecture program at l'École nationale supérieure des Beaux-Arts in Paris and the first woman architect licensed in California. But it wasn't until 2014 that she became the the first woman to receive American Institute of Architects’ highest award, the AIA Gold Medal, posthumously.

In the New Angle: Voice podcast, "Hear from historians, family, colleagues, and the women themselves, how it was to be an architect coming up in the early 20th century. Imagine sitting with these pioneering women, who opened up the magic of the built environment professions to all who had the gifts, grit and persistence to endure."

At a glance, the border between the United States and Canada would seem to be at the friendlier end of the international boundary spectrum. But even though the US-Canada border is now pretty tame, when two countries touch each other over a stretch of 5500 miles, it can result in some surprisingly weird disputes, misunderstandings,  geographical quirks and ...really good stories.

Margarine is yellow, like butter, but it hasn't always been. At times and in places, it has been a bland white, or even a dull pink. These strange variations were a byproduct of 150-year war to destroy margarine, and everything that it stands for. During this epic fight for survival, margarine has had to reinvent itself, over and over again. 

I Can't Believe It's Pink Margarine

Rioters carried many familiar flags during the January 6th insurrection at the United States Capitol -- Confederate, MAGA, as well as some custom-made ones like a flag of Trump looking like Rambo. Except for onlookers who were already familiar with the design, it would have been easy to overlook one particular bright yellow flag with three red horizontal stripes across the center. This was the flag of South Vietnam.

There were actually several confounding international flags present at the Capitol riot that day: the Canadian, Indian, South Korean flags, all were spotted somewhere in the mayhem. But what was peculiar about the Vietnamese flag being there was that it's not technically the flag of Vietnam but the Republic of Vietnam, a country that no longer exists. And what this flag stands for (or should stand for) remains a really contentious issue for the Vietnamese American community.

The Sears & Roebuck Mail Order Catalog was nearly omnipresent in early 20th century American life. By 1908, one fifth of Americans were subscribers. Anyone anywhere in the country could order a copy for free, look through it, and then have anything their heart desired delivered directly to their doorstep. At its peak, the Sears catalog offered over 100,000 items on 1,400 pages. It weighed four pounds. Today, those 1,400 pages provide us with a snapshot of American life in the first decade of the 20th century, from sheep-shearing machines and cream separators to telephones and china cabinets. The Sears catalog tells the tale of a world -- itemized. And starting in 1908, the company that offered America everything began offering what just might be its most audacious product line ever: houses.

When it comes to English spelling and pronunciation, there is plenty of rhyme and very little reason. But what is the reason for that? Why among all European languages is English so uniquely chaotic today?

To help us answer that question, we spoke with linguist and longtime friend of the show, Arika Okrent, author of the new book Highly Irregular: Why Tough, Through, and Dough Don't Rhyme and Other Oddities of the English Language. In it, Arika explores the origins of those phonetic paradoxes, and it turns out some of the reasons for confusion are as counterintuitive as the words themselves.

Presidential libraries are tributes to greatness, "[a] self-congratulatory, almost fictional account of someone's achievements, where all the blemishes are hidden," explains one New York architect.  But they're also a "weird mix of a historical repository of records and things that have a lot of meaning." Studying their origins and evolution, one can begin to see how presidential libraries have always involved tensions and contradictions.

The premise of using the extreme example of Trump to heighten the contradictions of executive branch norms is what we do on Roman's other podcast What Trump Can Teach Us About Con Law. It's good! And it's not really about Trump, so don't worry. It's essentially a current events based Constitutional Law class taught by an incredible professor, Elizabeth Joh. We included the latest episode here for you to check out.

The great Jacob Goldstein, author of Money: The True Story of a Made Up Thing, stops by to tell us two stories about the design of paper currency around the world. First, the story of the making of the Euro banknotes, the design of which was supposed to unify Europe and not rely on any one country's national heroes or monuments. Then we learn about China's early pioneering experiments in paper currency, hundreds of years before it caught on in the rest of the world.

Axolotls are nature’s great regenerators. They are able to grow back not just their tails, but also legs, arms, even parts of vital organs, including their hearts. This remarkable ability is one of several traits that turned the axolotl into a scientific superstar. The axolotl is one of the most abundant laboratory animals in biology. They can be found swimming in tanks at universities all around the world. But in the wild they’ve only ever been found in one place: Mexico City.
