Underground Sleeping Situation

Bunking in Bunkers

Going Underground

Gentrification . . . of a Sort

In the 1960s and 70s, Maoist China constructed a massive series of fallout shelters underneath their cities for fear of nuclear war. Beijing had 10,000 such bunkers, with many more constructed across the nation. Now, however, that the Cold War has ended and fear of nuclear war has receded, those bunkers are seeing new life.

Every night, more than a million inhabitants of Beijing bed down inside these underground bunkers. They're largely migrant workers and poor rural students, and the conditions they live in are often quite harsh. The bunkers have been subdivided into countless micro-apartments, and people are crammed into these spaces like stacked logs.

While laws dictate a minimum size for the micro-apartments, they're often ignored. It's not uncommon to find an entire family living in a room only large enough for a bed. Mold is common, and the lack of sunlight and ventilation certainly isn't healthy.

Despite government efforts to clean up the bunkers, there isn't anywhere else for these people to go. Housing and rental prices in Beijing have skyrocketed to utterly unsupportable levels.

This isn't even remotely an uncommon phenomenon, either: across the globe, cities have rampant housing crises as the global population increasingly urbanizes. It's happening here in America, as well. New York, for instance, is famous for having the highest density of poor artists per apartment of any major developed city. (If there's not at least two musicians and a cartoonist in your closet, you're not using your space correctly.)

Unfortunately, we don’t have a one-size-fits-all solution. In New York much of the problem comes from issues like the ultra-wealthy buying multiple luxury residences and leaving them unoccupied. The problem is completely different in China, where rural populations are abandoning their traditional ways of life en masse.

Cities and governments across the world are facing this problem, and how they respond is absolutely critical.

Me? I fantasize about finding a cabin out in the country with no neighbors for miles. People are too much trouble most of the time.

Finishing Corinth Canal

Or: Taking Their Time to (Not) Get it Right

That's Some Celebration

The longest construction project in history lasted almost two thousand years.

The Corinth Canal is a four-mile-long, seventy-foot-wide canal that separates the Peloponnese peninsula from mainland Greece, technically making it an island.

The Corinthian Tyrant Periander first proposed the canal in the seventh century BCE. It swiftly became too expensive, and Periander instead constructed a Diolkos, a stone road designed to use to drag (or portage) ships across the narrow isthmus. (You can still see remnants of the Diolkos alongside the canal.)

The canal idea was next resurrected in the third century BCE by Diadoch Demetrius Poliorcetes, one of the generals who warred over the remnants of Alexander the Great's empire after his death. His surveyors, however, miscalculated and feared that the canal would result in large-scale flooding, so the project was abandoned.

Roman Emperors Julius Caesar and Caligula both considered constructing the canal, but both were assassinated before they could begin. Emperor Nero became the first ruler to actually move forward with the construction of the canal—and, in fact, was the first person to labor on it, digging up the first basket of soil with a pickaxe. Construction officially began in 67 AD, after centuries of false starts.

Almost immediately afterward, of course, Nero got assassinated.

For nearly two thousand years after that, the idea never progressed farther than another proposal. Several conquerors of Greece throughout its history considered the idea, but nothing happened.

Then, in the 1830s, Greece gained its independence from the Ottoman Empire. New proposals immediately started back up, and construction finally started in the 1880s. (That’s a pretty short amount of time, as far as the Corinth Canal goes.)

Finally, on July 25, 1893, Greece completed the Corinth Canal. And, of course, it was too narrow, too windy, and had currents that were too severe for it to be of much use, except to a small number of ships a year.

Cold Welding

Or: One Advantage of Being Messy

cold welding

Shut the door, please.

On June 3, 1965, a door failed to close.

In most situations, this would be a minor annoyance, but this was in the middle of the Gemini 4 space mission, and the door in question was the outer airlock door of the capsule—while they were in space.

So, yes: this was rather a big problem. In the end, the problem turned out merely to be a jammed spring; they managed to get the door shut. There were serious concerns, however, that a more severe problem might have occurred: cold welding.

Cold welding is exactly what it sounds like: Two pieces of metal welding together in cold conditions, rather than through application of heat. Specifically, it involves two clean, flat pieces of metal bonding together when they contact in a vacuum.

These need to be two exceptionally clean pieces of metal, since any contaminants can interfere with the process. Once they're welded, however, as far as the two pieces of metal are concerned, they're just one piece, not two. The process actually bonds the two together as if they'd always been one piece.

Needless to say, this is a big concern in space, where you really can't afford to have random mechanical failures due to pieces deciding they don't want to move.

Quite a few satellites have been lost through cold welding over the years, and the Galileo probe sent to Jupiter had its high-power antenna welded shut in this way.

There are a few good methods to help prevent cold welding these days—using plastic, ceramics, and coatings whenever possible, as well as making sure that any metals in or near contact with one another are different metals, to reduce risks of cold welding.

Finally, we have one more thing protecting us: our natural messiness. Skin oil, dust, and other contaminants can help prevent cold welding. And, guess what? We're really good at getting all that stuff on everything, even our super-expensive, high-tech space probes. Three cheers for being messy.

Modern Problems: Balinese Rice

Meet the New Boss, Not as Good as the Old Boss

The Ramp Rules, Unless You're Talking Rice

Sometimes . . . The Rice Rules

There’s a long list of stories in history where Europeans tried, and miserably failed, to apply European farming techniques to other places around the world.

It turns out that you need to adapt your techniques to your environment, not the other way around. The Ancient Greeks had a relevant term: metis, or local knowledge. It’s important to know how things work where you live.

One of the most interesting European agricultural failures occurred in Bali. The Balinese had, over millennia, developed incredibly complex rice farming techniques. Rice is absolutely central to Balinese Hinduism and cuisine. Rice is so important that the Bali word for rice, nasi, means “food.”

Incredibly complex water terraces cover Bali, running up and down hillsides, with equally complex irrigation systems all over the place. They have farming cooperatives known as subaks that consist of every farmer sharing a water source. Everything is orchestrated by the intricate and complicated calendar known as the tika. And, thanks to all of that, Bali was able to maintain an immense population density.

Rice is Essential

Yours truly, about to order a rice dish.

Then the Europeans came along, decided all of these old methods were nonsense, and decided to replace them with more modern techniques. They failed to significantly change anything.

After Indonesia gained independence, the Indonesians, in an effort to modernize, began applying those same European techniques in Bali. The water districts quickly fell into mismanagement: the new rice strains they’d introduced were more vulnerable to pests, and uniform rice crops were more vulnerable to disease, etc., etc.

In the 1980s, scientists began actually modeling the differences between the old and new systems and realized exactly how brilliantly adapted the old systems had been to Bali’s climate and ecosystem. Today, Bali has slowly reintroduced modified versions of the old system back in place. They’re not bringing back the old rice strains, but they’re reworking things to run off the tika calendar again.

It pays to understand your environment. The real world always beats theories.

The Golden Repair

Making Lemonade: Pottery Version

Succeeding...where Humpty Dumpty didn't.

Kintsugi Action Figure

When we break a vase or a bowl, most of the time we just throw it away. We might be upset about breaking Grandma Esmeralda’s keepsake, but it's still usually going in the trash.

On the rare occasions when we try to repair it (say, under orders from Grandma Esmeralda’s daughter), we do our best to make sure that the repairs are as inconspicuous as possible.

In Japan, however, they do the complete opposite.

When a piece of Japanese ceramics breaks, they actually seal it back together with precious metal—gold, silver, or a lacquer containing powdered gold. The result is that they emphasize the breaks.

The art is known as kintsugi, which comes from a combination of kin (golden) and tsugi (repair). The fundamental philosophy of kintsugi is one that treats breaks and repairs as part of the history and essence of an object, not merely a mistake to be hidden. It's also an embracing of imperfection, which—if you ask me (or Grandma Esmerelda’s daughter)—can oftentimes be a pretty healthy attitude.

One reason this might not be as present in the West? The greater role of plastic. We use plastic constantly, and, unlike just about everything else, plastic ages terribly.

Old wood, pottery, or metal ages into beautiful antiques, but old plastic? It just looks terrible. There's no reason not to treat plastic as disposable in this sense.

The situation goes well beyond that. We've got a general culture of disposability. The huge geographical size of America means we have no problems creating huge garbage dumps wherever we want. American consumer culture demands that we keep filling our homes with the cheap stuff.

Of course, Japan isn't completely blameless in this regard. They have plenty of cheap disposable stuff they also throw away. Disposable wooden chopsticks, or waribashiare notable offenders, resulting in massive deforestation every year.

Still: kintsugi offers us an interesting pathway toward rethinking the way we deal with the objects in our lives.
