What's the Difference Between Art Deco and Art Nouveau?

The Quick Trick: It all comes down to "flowery"vs. "streamlined." Art Nouveau is the decorative one. Art Deco is sleeker.

The Explanation: Both the Art Nouveau and Art Deco movements emerged as reactions to major world events; the Industrial Revolution and World War I, respectively. While both embraced modernist elements, they're easy to distinguish if you know what to look for.

Art Nouveau (it means "new art," but you probably figured that out) reigned from roughly 1880 until just before World War I. Art Nouveau embraced Europe's new industrial aesthetic rather than challenging it. It features naturalistic but stylized forms, often combined with more geometric shapes, particularly arcs, parabolas, and semicircles (think of the paintings of Gustav Klimt, or the arches of the Eiffel Tower). The movement brought in natural forms that had often been overlooked, like insects, weeds, and even mythical faeries, as evidenced by Lalique jewelry or Tiffany lamps. The black and gold robe Kate Winslet doffs in the erotic portrait session scene in Titanic is quintessentially Art Nouveau.

Art Deco, on the other hand, emerged after World War I. In fact, the deprivations of the Great War years gave way to a whole new opulence and extravagance that defined the Jazz Age and the Art Deco aesthetic. The movement took its name from the 1925 Exposition Internationale des Arts Décoratifs et Industriels Modernes, which was held in France. The style was prevalent from the 1920s until roughly the start of World War II and is characterized by streamlined and geometric shapes. It also utilized modern materials like chrome, stainless steel, and inlaid wood. If Art Deco dabbled with natural materials, they tended to be graphic or textural, like zebra skin or jagged fern leaves. As a result, Deco featured bold shapes like sunbursts and zigzags and broad curves. In fact, if you check out the spire of the Chrysler Building, the hotels of Miami's South Beach, or the "coffin nose" of a 1935 Cord Model 810, you'll be staring at the very definition of Deco.

Of course, you don't have to go outdoors if you're looking for Deco. Furniture from the period—like the black leather and chrome chaise longue by Le Corbusier or the Barcelona chair by Bauhaus giant Ludwig Mies van der Rohe—is still coveted by design aficionados and can be found in finer hotel lobbies everywhere.

Looking to Downsize? You Can Buy a 5-Room DIY Cabin on Amazon for Less Than $33,000

Five rooms of one's own.

If you’ve already mastered DIY houses for birds and dogs, maybe it’s time you built one for yourself.

As Simplemost reports, there are a number of house kits that you can order on Amazon, and the Allwood Avalon Cabin Kit is one of the quaintest—and, at $32,990, most affordable—options. The 540-square-foot structure has enough space for a kitchen, a bathroom, a bedroom, and a sitting room—and there’s an additional 218-square-foot loft with the potential to be the coziest reading nook of all time.

You can opt for three larger rooms if you're willing to skip the kitchen and bathroom.Allwood/Amazon

The construction process might not be a great idea for someone who’s never picked up a hammer, but you don’t need an architectural degree to tackle it. Step-by-step instructions and all materials are included, so it’s a little like a high-level IKEA project. According to the Amazon listing, it takes two adults about a week to complete. Since the Nordic wood walls are reinforced with steel rods, the house can withstand winds up to 120 mph, and you can pay an extra $1000 to upgrade from double-glass windows and doors to triple-glass for added fortification.

Sadly, the cool ceiling lamp is not included.Allwood/Amazon

Though everything you need for the shell of the house comes in the kit, you will need to purchase whatever goes inside it: toilet, shower, sink, stove, insulation, and all other furnishings. You can also customize the blueprint to fit your own plans for the space; maybe, for example, you’re going to use the house as a small event venue, and you’d rather have two or three large, airy rooms and no kitchen or bedroom.

What Is the Citizenship of a Baby Born on an International Flight?

It's pretty standard medical advice: a pregnant woman shouldn’t travel via airplane 36 weeks or later into her pregnancy. Despite that precaution, an occasional bundle of joy may still add an unexpected passenger to the flight manifest. As if giving birth at 40,000 feet wasn't already a stressful experience for a new mom, things can get even more hectic upon landing: Depending on the details surrounding the birth, her newborn’s citizenship could be up for debate.

There is no universal rule for how a country determines the citizenship of a newborn. Some countries just follow the jus sanguinis (right of blood) law, which means a baby’s nationality is determined by that of one or both parents. Others observe that rule and jus soli (right of the soil), where a country grants citizenship to a baby that’s simply born on its soil, regardless of the parents’ origin. These countries are mostly in the Americas and include the United States and Canada. And with the expansion of air travel, these laws had to extend to the heavens as well.

If a baby is born over United States airspace, the jus soli rule means the child would be granted U.S. citizenship, according to the Department of State Foreign Affairs Manual. Depending on the circumstances, the child may also be a candidate for dual citizenship if its parents are from a country that grants citizenship based on blood—though that would depend on the countries involved.

This same simplicity doesn’t extend to a jus sanguinis country, though. This means that an American mother can’t attain French citizenship for her baby just because she gave birth over French airspace. The baby would simply revert to the parent's U.S. citizenship, since the United States also generally follows jus sanguinis when a baby is born to U.S. citizens in a foreign country. Since jus sanguinis is the far more common rule around the globe, most babies born on a flight over international waters or foreign airspace will likely wind up taking the citizenship of its parents.

If there’s a case where the child could potentially be stateless—such as when a mother herself has no official citizenship and the baby is born in international airspace—the baby would likely take the citizenship of whatever country the plane itself is registered in, according to the United Nations’s Convention on the Reduction of Statelessness agreement.

Despite all these complex laws, mid-flight births are exceedingly rare—so rare, in fact, that most airlines don’t even keep track of the number of babies born in the air. An expecting mother likely wouldn't even be able to get onto a flight in the first place, since many airlines have rules that prohibit women from flying after they've reached a certain point in their pregnancy.
