Straw Bale Houses / The power of banding together

artificial intelligence 5291510 1920

Several years ago, the company I worked for had a big Halloween celebration. One of my coworkers decided that a group of us needed to dress up as the Three Little Pigs and the Big Bad Wolf. So she worked for days sewing costumes for all of us, and even brought in plastic pig noses for us to wear. For an authentic touch, she asked that we also decorate our desks with the building materials featured in the story. I got the short straw (so to speak) and ended up making a pathetic mess by scattering straw all around my desk, and the “pig” who used sticks didn’t fare much better. But our colleague with the brick “house” simply printed out a huge brick pattern on a large-format color printer and wrapped it around his desk. In life as in the story, his design was clearly the best.

It is difficult to set aside the bias that straw is an inappropriate building material, even knowing that wolves lack the lung capacity to blow down a straw house. And yet people have been building sturdy, comfortable houses out of straw bales for more than a century. This building technique has been, shall we say, a bit slow to catch on—and is not without its limitations. But using straw as a building material turns out to have some interesting merits.

If You Can’t Eat ‘Em…

Straw is what’s left over when grains like wheat, barley, or rice are harvested—basically the hollow stalks. Unlike hay, which can be used to feed animals, straw is a nearly useless agricultural byproduct. Millions of tons of straw must be burned or otherwise disposed of each year. Inconveniently, it doesn’t even decompose rapidly. Automated baling machines, invented in the 1890s, compact straw into tightly compressed blocks, so that they will at least occupy as little space as possible. Faced with a surplus of straw bales, a lack of trees, and a cold winter approaching, some settler long ago decided to stack up the bales and use them as the walls of a house. This worked surprisingly well, and after years of refinement, straw bale construction is beginning to gain respect as a mainstream technique.

Walls made of straw bales are held together and reinforced with rebar (or sometimes, wooden or bamboo stakes). In some designs, walls made entirely of straw bales support a roof; in others, a conventional wooden frame is used as the load-bearing structure while the straw bales form the exterior shell. Straw will rot if exposed to moisture, so to keep it dry, both interior and exterior surfaces are sealed with plaster, stucco, or adobe. The net effect is that walls of a finished straw bale building look just like any other wall, only a bit thicker.

The Last Straw

One of the strongest arguments for using straw as a building material is that it saves lumber. Even if wood is readily available, straw is invariably much cheaper. It’s a rapidly renewable resource, and one that usually goes to waste. A wall made of straw bales also has dramatically higher insulating properties than a standard wooden wall, making buildings that use them very energy-efficient. Straw bale houses are also easier to build than wooden frames, even by people with little experience.

Studies performed by various universities and government organizations have shown that a properly constructed straw bale house, sealed well with plaster, is actually less susceptible to damage by fire than a wooden building. Although you wouldn’t build a high-rise condo out of straw bales, a carefully designed one-story building is also quite safe in an earthquake. Owners must be careful to keep all cracks sealed, though, because once infiltrated by moisture, bugs, or rodents, a straw bale wall will rapidly lose its integrity. Last but not least, straw bale buildings are extremely resistant to damage by wind. So much for the Big Bad Wolf. —Joe Kissell

Esperanto / Artificial language for the masses

artificial intelligence 5291510 1920

Like many people, I endured four years of high-school French only to find that I lacked the ability to order a croissant in a Paris bakery without making a fool of myself. I eventually got the hang of basic conversation in French, but then found myself traveling to places where Spanish, German, or Italian (for example) were spoken, and having to start all over again with the basics (“Where’s the bathroom?” “How much does this cost?” “Where have you sent my luggage?”). As much as I enjoy and appreciate linguistic diversity, it can make travel, trade, and diplomacy challenging at times.

In some heavily multilingual areas of the world, most people learn a lingua franca—a regional trade language—in addition to their mother tongue. It stands to reason, then, that this notion could be expanded more broadly. But when someone proposes English or French, say, as a trade language, objections inevitably arise. These languages are notoriously difficult to learn, with strange spellings and lots of grammatical rules and exceptions. But more importantly, they’re loaded with historical and cultural baggage. If your country—not mentioning any names—has been a rival of English- or French-speaking nations, you will likely not jump at the chance to spend long years learning a language with such unpleasant associations. The only hope for a truly universal language would seem to be an artificial one—a language that is designed to be free from cultural biases and easy to learn. This was precisely the goal of Esperanto.

Hoping for a New Language

L. L. Zamenhof grew up in the late 1800s in Warsaw (part of Russia at that time). While still in high school he set out to design a universal artificial language that would facilitate communication within his linguistically diverse community. By the time he finished this side project ten years later, Zamenhof was a practicing ophthalmologist. In 1887, he published the first guide (in Russian) to the new language, which he called “Lingvo Internacia” (international language). Zamenhof wrote the textbook under the pseudonym “Esperanto,” meaning “a person who is hoping” in Lingvo Internacia. Fans of the language decided that “Esperanto” had a nicer ring to it, and they soon adopted it as the informal name of the language.

Esperanto was designed to be both easy to learn and culturally neutral. According to some sources, an English speaker can learn Esperanto up to five times faster than Spanish. For starters, Esperanto uses strictly phonetic spelling—a given letter always makes exactly the same sound. Second, the structure of Esperanto is very simple, with only sixteen basic grammatical rules that need to be learned—and no exceptions to the rules (such as irregular verbs). And third, Esperanto has a very small core vocabulary; new words are constructed by combining words and adding prefixes and suffixes. (Esperanto is thus an agglutinative polysynthetic language, for those who need to have such things spelled out…)

Something Old, Something New, Something Borrowed

The vocabulary of Esperanto will have a familiar ring to anyone who knows a European language, as roots were borrowed from French, German, and Spanish, among other languages. (A few examples: bona means “good”; porko means “pig”; filo means “son”; hundo means “dog.”) One could argue that this selection represents not so much cultural neutrality as Euro-neutrality, but this hasn’t prevented Esperanto from becoming popular in China and some other parts of Asia.

For all its merits, Esperanto has not reached the level of acceptance its creator foresaw more than a century ago. There may be as many as two million people who speak Esperanto with at least a moderate level of proficiency, but probably no more than a few hundred who learned Esperanto at home as their first language—and no known speakers (over the age of three or so) who speak only Esperanto. Ironically, the cultural neutrality that is touted as such a benefit of the language also serves to limit its growth, because languages tend to spread along with the cultures that gave rise to them. Alas, unless or until the number of Esperanto speakers reaches a larger critical mass, it will be of little value as a trade language, and without a clear value, it will be difficult to convince people to learn it. —Joe Kissell

Geodesic Domes / Building outside the box

artificial intelligence 5291510 1920

Unless you’ve been living in a cave for the past half century, you have probably encountered a geodesic dome at one time or another. They can be found on playgrounds, at amusement parks, and in museums; and any number of homes and public buildings are constructed using some variation of this structure. Depending on your tastes and disposition, you may think geodesic domes look cool, endearingly retro, or woefully unfashionable. But you may not know the story (and the logic) behind this sometimes-controversial design.

Bucky-ing Trends

R. Buckminster Fuller was one of the most prolific thinkers and inventors of the 20th century. He wrote numerous books, received dozens of patents, and worked tirelessly for decades to solve some of the world’s most vexing problems using the tools of engineering and common sense. For all his innovations, Fuller was a very practical man, and like most engineers he saw a great beauty in elegantly logical solutions—even if they defied tradition, aesthetics, or conventional wisdom. So when a housing crisis arose in the years following World War II, he set out to find the simplest and most effective solution, no matter how unusual it may be.

Fuller loved geometry, and he was particularly impressed by the triangle, the most stable geometrical shape. Many of his building designs involve triangles, because they provide the greatest structural integrity. He also knew that the sphere was the most efficient three-dimensional shape, enclosing the largest possible volume with the smallest surface area—meaning a dome (a partial sphere) should be a logical shape for a building. But dome-shaped buildings are notoriously awkward to construct. Fuller’s innovation was a way to create a sphere (or partial sphere) out of triangles, providing the best of both worlds. He called this shape a geodesic dome, because the pattern of triangles forms an interlocking web of geodesics. A geodesic is the shortest path between two points. This is, of course, a line in two-dimensional geometry, but on the surface of a sphere, the shortest distance between two points is an arc defined by a great circle—a circle with the same diameter as the sphere (like the equator).

The Miracle Building

If all that geometry is too much to wrap your brain around, consider the main advantage Fuller cited in his 1954 patent application for the geodesic dome: this shape, because it is self-reinforcing, requires far less building material than any other design. Conventional buildings, according to Fuller, weigh about 50 pounds (22.7kg) for each square foot (0.09 sq meter) of floor space. A geodesic dome can weigh less than 1 pound (0.5kg) for each square foot of floor space. (One of Fuller’s original geodesic domes was a metal framework lined with a sheet of heavy, flexible plastic.) The upshot of this is that you can create buildings very inexpensively, and with a minimum of equipment and labor. Geodesic domes are also stronger than conventional buildings, highly resistant to earthquakes and wind, and more energy-efficient too. What’s not to like?

Well, that’s a circular question. The main problem with a dome-shaped building is that although it encloses a large volume of space, a lot of that space is not easily usable by humans. The slope of the walls means the floor space is effectively limited (more so, the taller you are), and most furniture, having been designed for flat walls and corners, doesn’t fit well. There’s also the fact that you need a fairly large lot for a dome of any reasonable height; in urban areas, such real estate may be hard to come by. And banks are generally hesitant to provide home loans for dome builders; they’re seen as a risky investment, because there’s no way to gauge their resale value.

All these issues in no way diminish my enthusiasm for Fuller’s design, because, as he did, I feel that logic and elegance count for a lot. Plus—let’s not beat around the sphere—I think geodesic domes look very impressive, and I imagine it would be interesting to live in a space without right angles. If fortune ever smiles upon me broadly enough that I can afford to build my own home, you can be certain a dome will find its way into the design somewhere. —Joe Kissell

Performative Verbs / Doing as you say

In a sociolinguistics class years ago, each of the students had to complete a major project on the topic of their choice, and the professor met with each of us to discuss what sorts of things we were thinking of researching. I described some areas of interest, and my professor said, “You should read J.L. Austin’s How to Do Things with Words. I think it’s exactly the kind of thing you’re talking about.” I read the book, and although it was not at all relevant to the project I had in mind, it was quite interesting. The entire book was a treatise on performative verbs, which is to say, verbs whose action is accomplished merely by saying them.

I Speak, Therefore I Act

Performatives sound a bit mystical at first, like a spell or incantation. But in fact such verbs are quite commonplace. If you’ve ever said, “I promise” or “I apologize,” you have performed those actions by the simple act of saying them. You’re not talking about doing these things or stating that you’re doing them; you’re actually doing them. The same is true when you say, “I bet,” “I invite,” “I request,” or “I protest,” for example. There are countless other examples, such as:

  • I now pronounce you husband and wife.
  • I’m warning you, don’t go in there.
  • I thank you for your kind attention.
  • You’re fired!
  • I must ask you to leave now.
  • I christen this ship The Daydream.
  • I claim this land in the name of the king of England.

Among Austin’s points in his discussion of performative verbs is that they look exactly like declarative statements, yet they aren’t. “I run this meeting” has the same grammatical form as “I adjourn this meeting,” but the first one is declarative while the second is performative. One of the consequences of this peculiarity is that unlike regular declaratives, performatives cannot be evaluated for truth or falseness. The sentence “You’re happy” can be true or false, but “You’re fired,” if uttered as a performative, is neither true nor false. And yet, there must be some way of evaluating the meaning of such a sentence. After all, if I walked up to a politician I didn’t like and said, “You’re fired,” my doing so would not in fact terminate that person’s employment, whereas it would if I said it to someone who worked for me. Austin used the terms felicitous and infelicitous to describe whether a performative utterance is effective—whether it works. If social conventions are followed and my intentions are sincere, a performative utterance will be felicitous. If I do not have the authority to use a certain verb performatively in a certain context—or if I’m joking, or acting, for example—the very same utterance will be infelicitous.

 

I Hereby Insult You

There are several other curious facts about performative verbs. For one thing, you can nearly always perform the action specified by a performative verb without actually using the verb. For instance, you can promise to do something by saying, “As surely as the sun rises each morning, I will repay you the cost of lunch.” Or you can apologize by saying, “I’m sorry.” Conversely, you can make a statement that sounds just like a performative, but is simply an ordinary declarative. For example, the expression “I apologize” could be a statement about what I habitually do. (“What happens when I step on someone’s toe?” “I apologize.”) In addition, some activities that seem like good candidates for performative verbs turn out not to fit the pattern. If you said, “I insult you,” that would not constitute an insult; saying “I swear at you” doesn’t mean you have done so. (On the other hand, “I swear to tell the truth” is a performative utterance.)

Ever since I read Austin’s book more than a decade ago, I’ve been more aware of the use of performative verbs, and more likely to use them myself. In some strange way, using words to perform actions feels both elegant and powerful. But don’t take my word for it—try it yourself. I insist. —Joe Kissell

Ice Hotels / In-refrigerator rooms

artificial intelligence 5291510 1920

When I first heard about an “ice hotel,” I thought it must be a joke. I’ve heard of igloos, of course, but that’s not really the image that comes to mind when I think hotel. Sure, there was the Bad Guy’s ice lair in the James Bond film “Die Another Day,” but that’s just fantasy, right? The thought that someone might really construct an entire hotel out of ice, rent rooms, and then repeat the process each year was almost too wacky to believe. Believe it—not only does it happen, it has now become the trendiest way to spend a winter vacation.

They’ve Got It Down Cold

The first ice hotel was built in 1989 in a village called Jukkasjärvi in northern Lapland, Sweden. That first year it was a modest, 60-square-meter igloo; this year, the structure measures over 4,000 square meters and has 85 rooms. Construction begins each year in October, and the hotel is open for guests from December through April (weather permitting). By summer the hotel has melted, but plans are already underway for next year’s bigger, better ice structure.

Ice hotels are built, naturally, entirely out of frozen water in the form of ice blocks and hard-packed snow. In some cases, blocks of ice are sawed from a river; for other parts of the building snow is compressed into wooden forms to create building blocks. The guest rooms contain beds made of a block of ice and topped with a foam mattress. You sleep in high-tech mummy-style sleeping bags covered with animal pelts; although the air temperature in the room is below freezing, your body remains toasty warm. If nature calls in the middle of the night, you can head to an adjoining heated building with conventional facilities. Outhouses would not be much fun, as the exterior temperature frequently reaches –40°.

Put It on Ice

But a classy hotel is much more than a place to sleep, and at the prices of these rooms, you’d better get much more than a sleeping bag. Although the design changes from year to year, Sweden’s Icehotel invariably includes an ice bar for vodka-based drinks (beer would freeze); even the glasses and plates are made of ice. There’s also an ice chapel for “white” weddings, an ice cinema, an ice sauna (I have yet to figure that one out), ice art galleries, and even—I am not making this up—a replica of Shakespeare’s Globe Theatre built of ice. Most guests stay only one night in an ice room; ordinary heated hotel rooms are available nearby for longer stays. Even so, the hotel has a waiting list several years long.

Sweden’s Icehotel was the first, but imitators are appearing all across the Arctic Circle. In Kangerlussuaq, Greenland you can find the more modest Hotel Igloo Village, with six adjoining igloos (four of which serve as guest rooms). If you want the igloo experience in Greenland during the summer, you can also stay at the Hotel Arctic in the town of Ilulissat, where guests enjoy all the comforts of home in melt-proof aluminum igloos. For the past five years, Québec has had its own Ice Hotel, modeled on the original Swedish Icehotel and rivaling it in size and luxury.

In 2004, the United States saw its first ice hotel—the Aurora Ice Hotel at the Chena Hot Springs Resort in Fairbanks, Alaska. During its construction, state officials cited the hotel’s owner for fire code violations and did not permit the building to open until smoke detectors and fire extinguishers had been installed in each room. (I’m not kidding. Only in America.) Although the initial structure melted in the spring of 2004, it was rebuilt for the 2005 season, this time inside a larger, refrigerated structure—with the goal of keeping it frozen and habitable year-round.

As far as I know, I’m not personally acquainted with anyone who has stayed at an ice hotel. I rather suspect—marketing hype and high prices notwithstanding—that it would be a decidedly uncomfortable experience. But then, many uncomfortable experiences are worth having, and it’s not every night you get to drink vodka out of an ice glass while watching the Northern Lights, and then sleep on a slab of ice.

Spoonerisms / Sixing up mounds

artificial intelligence 5291510 1920

One of my linguistics professors in grad school had a strange sense of humor that appealed to me greatly. He didn’t see a need to divide work and pleasure; exams regularly contained jokes, puns, and strange juxtapositions, and every class session was filled with laughter. When this professor needed to make up a word in an imaginary language to use as an example, he wouldn’t give it a common meaning like “mother” or “tree”; he’d instead gloss the word as “flagpole sitter,” “hubcap thief,” or something similarly odd. He constantly urged us not to take our homework too seriously and to ask annoying questions of the other professors. I think this lighthearted attitude helped us all to learn better, and it certainly brightened the classroom atmosphere.

How Near This

Class discussion had a remarkable tendency to stray from the planned lesson, though invariably it went in interesting (and linguistically useful) directions. One day, someone in the class mentioned the word metathesis, which is the phenomenon that occurs when two adjacent sounds are swapped (as in “aks” for “ask”). Without missing a beat, the professor said, “Oh yes, this reminds me of spoonerisms,” and proceeded to recite, rapidly and perfectly, the tale of the Mion and the Louse. We were stunned and delighted by his brilliant display of linguistic prowess. It’s not easy to make mistakes like that on purpose.

A spoonerism is like metathesis but instead of affecting adjacent sounds within a single word, it’s spread out across two or more words (sometimes with intervening words)—for example “hat rack” becomes “rat hack”; “light a fire” becomes “fight a liar.” Some spoonerisms instead transpose vowel sounds (“I fool like a feel” instead of “I feel like a fool”). Because mistakes like this are involuntary slips of the tongue, they don’t always result in real words (you might say “key tup” for “tea cup,” for instance), but the funniest and most memorable spoonerisms change the meaning of a sentence completely (as in “I’m biting a rook” in place of “I’m writing a book.”)

A Speecher Named Tuner

I have mentioned my hope that my name never gets distorted into an adjective or other part of speech. But if history remembers me for anything, I trust it will be for something more auspicious than a tendency to mix up my words, as was the case with the Reverend William Archibald Spooner, a member of New College, Oxford, from 1862 to 1924. Spooner was a small man and an albino. His head was disproportionately large, and he had poor eyesight. But he was kind, well-liked, and extremely intelligent—so much so that his mouth couldn’t keep up with his brain. He therefore developed a reputation for frequent verbal blunders.

Spooner himself was seldom aware of making these mistakes, and some people believe the quotes attributed to him were apocryphal. In any case, he is credited with such classics as “a blushing crow” (instead of “a crushing blow”), “you’ve tasted two worms” (instead of “you’ve wasted two terms”), and a toast to “our queer old Dean” (instead of “our dear old Queen”). He navigated the streets of Oxford on a well-boiled icicle, and reminded parishioners in one of his sermons that “the Lord is a shoving leopard.” By the time he was in his fifties, the term “spoonerism” had become a common noun, but as far as I can tell Spooner accepted this dubious distinction with gracious good humor. A legend in his own time, he lives on in our marts and hinds. —Joe Kissell

Origin of the Trophy Cup / Handing it to the winner

artificial intelligence 5291510 1920

Having written several articles based on the theme “Throwing Down the Goblet,” I found myself wondering about trophies. Lots of major sporting competitions award the winning team a trophy in the shape of a cup (or, if you prefer, a bowl, chalice, or goblet)—the Stanley Cup, the America’s Cup, the World Cup, and so on. Trophy cups are also found quite often in collegiate sports, and Harry Potter fans will of course remember the House Cup as the highly coveted award for the house that has accumulated the most points during a given term. Often, though not always, tradition dictates that a single trophy cup be passed from one winning team to the next. In individual competitions, by contrast, trophy cups are much less common; designs are based more often on a human (or angelic) figure of some kind.

The Salad Fork of Victory

When you’re rooting for your team to win, say, the World Cup, it’s probably not especially important to you what the actual token of victory is shaped like. The important thing, most competitors and fans would agree, is simply to win—and to have some commemorative token. A cube or sphere or an inscribed toaster oven could just as easily serve this purpose, though without a doubt, larger, more elaborate, and costlier trophies give the winner something further to brag about. All I wanted to know was, why a cup? How did a cup, of all things, come to symbolize competitive victory?

The answer has been surprisingly difficult to track down; in fact, after several hours of research I can only advance a couple of plausible theories. For many centuries, a “trophy” was simply something of one’s enemy—a piece of armor, perhaps, or occasionally a body part—that was displayed after a battle as a tangible proof of triumph. This may, of course, have been a cup on occasion, but I have not been able to find any examples of cups designed for the sole purpose of serving as trophies (in particular, for sporting events) until the mid-18th century. This means the inspiration for such a design must have appeared earlier than that.

For Methodists Who Love to Win

One explanation traces the origin of the trophy cup to the “loving cup” designed by theologian John Wesley (1703–1781). Wesley founded the Methodist church, and part of the church’s early rituals included “love feasts”—community gatherings that included a simple meal of bread and water. Although superficially similar to Holy Communion, love feasts were simpler and were conducted by laypeople rather than clergy. Wesley’s loving cup was given two handles so that the water could be passed easily from person to person. The handles and the tradition of passing the cup fit with the trophy cup, although I have not been able to find any explicit evidence that a trophy designer used the loving cup as inspiration.

An alternative theory is advanced by Ian Pickford (of Antiques Roadshow fame). According to Pickford, the modern trophy cup was based on the two-handled “ox-eye” college cup design from the 17th century. Far be it from me to gainsay an antiques expert, but I was not able to corroborate this claim—and even if true, it begs the question of where that design came from or how it came to have its current meaning. If any trophy historians out there would like to chime in with evidence supporting either explanation (or a different one), I’d be all too happy to set the record straight. —Joe Kissell

Cleopatra’s Wager / The most expensive meal in history

artificial intelligence 5291510 1920

A news article mentioned a hotel bar in New York whose drink menu includes a US$10,000 drink called “Martini on the Rock.” That works out to about $5 for the gin, vermouth, and olives—and $9,995 for the loose diamond sitting at the bottom of the glass. Patrons must order the drink three days in advance, and meet with a jeweler to pick out the perfect stone. The first person to order this drink paid a bit extra—$13,000—and instead of a loose stone, selected a 1.85-carat diamond engagement ring. (His girlfriend said yes.) Perhaps unknown to the hotel’s proprietors, this extravagant beverage has a fascinating historical precedent.

Et Tu, Cleo?

The year was 41 B.C. Mark Antony, one of the rulers of Rome, summoned Egyptian queen Cleopatra VII for an audience at Tarsus (in present-day Turkey). Antony ostensibly wanted Cleopatra to answer charges that she had aided Cassius, who had conspired with Brutus to assassinate Julius Caesar. But most people believe the real reason for the meeting was that Antony wanted Egyptian aid for an upcoming military campaign, and besides, he had the hots for Cleopatra.

Cleopatra arrived on her legendary barge, and proceeded to throw elaborate banquets for Antony and his officials for several evenings straight—nothing like a bit of wining and dining to smooth over political misunderstandings. So impressed was Antony at the lavish feasts Cleopatra had arranged that he accepted a friendly wager. Cleopatra bet Antony a large sum of money that she could host the most expensive meal in history. The next day, as the meal in question was nearing its end, Antony said that it had been terrific, but no more impressive than her other banquets—and certainly not worth the sum of money she had specified. At this, Cleopatra removed one of her pearl earrings and dropped it in a goblet of wine vinegar. Each of the pearls was so large and rare that it was extraordinarily valuable—estimates are usually expressed in extremely helpful terms such as “10,000,000 sesterces” or “100,000 gold aurei,” or “the value of 15 countries.” In any event, it was worth a fortune. The pearl dissolved in the vinegar, which Cleopatra then drank. Antony conceded defeat—the value of that single drink, let alone the banquet, had indeed been more than any meal in history.

I’ve Got a Crush on You

There are a number of different versions of this story, which originally appeared in Pliny the Elder’s Natural History. According to some versions, Cleopatra ground the pearl in a mortar before dropping it in the vinegar. That would have been a wise choice. Pearls, which are made primarily of calcium carbonate (the same material that forms stalactites, stalagmites, and tufa), will indeed dissolve in a mild acid such as vinegar, neutralizing the acid in the process. (This is how antacids work, by the way—check the label on a bottle of Tums and you’ll see that its main ingredient is also calcium carbonate.) However, this might take days for a whole pearl; a crushed pearl could dissolve in a matter of minutes.

Not only did Cleopatra win the wager, she won Mark Antony’s heart. Antony left his wife and moved to Alexandria. But ten years later, Octavius led Rome in a war against Egypt. He defeated Antony and Cleopatra, both of whom committed suicide shortly thereafter. Meanwhile, according to legend, the pearl from Cleopatra’s other earring was later cut in two, with each half being placed in one of the ears of the statue of Venus in Rome. Rome fell, of course, soon thereafter. Coincidence? Probably, but all the same, I recommend against sticking antacids in your ears. —Joe Kissell

The Invention of the Wheel / The best thing until sliced bread

artificial intelligence 5291510 1920

On occasion, you may have heard it said of some wonderful gadget, “This is the greatest invention since sliced bread!” Such a comment is intended to be both a compliment and a reference to how revolutionary and world-changing the invention is. It’s worth bearing in mind, though, that while people have been slicing bread for eons, pre-sliced, packaged bread has only been available since 1928, when Otto Frederick Rohwedder introduced the world’s first mechanical bread slicer in Battle Creek, Michigan. I don’t know what revolutionary invention the bread-slicer was compared to when it first appeared, but sooner or later, it all goes back to the wheel. Nobody seems to be able to come up with an older, or more important, invention than that.

Giving It a Spin

Before I began my curatorial duties here at Interesting Thing of the Day, I had never really wondered when the wheel was invented, much less why it was invented. That’s obvious, isn’t it? Everyone knows the wheel was invented to enable people to move stuff around more easily—a revolutionary alternative (so to speak) to carrying, pushing, or dragging heavy objects. Surprisingly enough, some historians and archeologists aren’t so sure about that. There is in fact a fairly good case for the hypothesis that the wheel was invented to facilitate pottery making.

The wheel was almost certainly invented in Mesopotamia—present-day Iraq. Estimates on when this may have occurred range from 5500 to 3000 B.C., with most guesses closer to a 4000 B.C. date. The oldest artifacts with drawings that depict wheeled carts date from about 3000 B.C., though for all anyone knows, the wheel was in use for centuries before these drawings were made. But there is also evidence from the very same period of time that wheels were used for pottery.

Drinking and Driving

It was around 3000 B.C. that the first goblets appeared. Clay goblets are normally made by throwing them on a wheel in two parts—first the bowl, then the stem (including the foot). This makes for a far more smooth and regular shape than could be achieved by manual coiling, and since the oldest surviving goblets bear the telltale signs of wheel manufacture, it is plausible that wheels were used for pottery before they were used for transportation. For that matter, it’s conceivable—though admittedly a wild and improbable speculation—that the wheel was invented for the express purpose of making goblets. Be that as it may, it is virtually certain that historically, the preferred way to make goblets was to throw them.

If the wheel was indeed invented for the convenience of potters, the question then becomes how it came to be used for transportation; clearly, whichever use appeared first, the other quickly followed. To be honest—putting myself as best I can into the sandals of someone living many thousands of years ago in Mesopotamia—I probably never would have thought to turn a pottery wheel on its edge and put it under a box (or vice-versa). But then, I’ve always had a knack for overlooking the obvious.

This story also has an interesting postscript. Some sources claim that prior to the invention of the pottery wheel, most pottery was primarily made by women, whereas afterward, it became a man’s job. Thus we can see that the stereotypical male trait of liking gadgets goes way back. I can just picture those prehistoric dudes standing around bragging about their new wheels and saying, “This is the greatest invention since fire!” —Joe Kissell

Sheets of ice found below Mars’ surface could be a boon for human exploration

If you look at a photo of Mars, you’ll mostly see red.The rust-colored world is known for its oxidized look, but if you dig down into the dirt, Mars gets a lot more interesting.The red planet is actually hiding pockets of water-ice up to about 100 meters thick just below its red surface, according to a new study published in the journal Science this week. The research found eight different pockets of ice of varying size not far below the planet’s surface.That ice could have implications for science, human exploration, and even long-term living on Mars.

“This ice is a critical target for science and exploration: it affects modern geomorphology, is expected to preserve a record of climate history, influences the planet’s habitability, and may be a potential resource for future exploration,” the study says.

While scientists have known that Mars is a pretty icy place for years, the new study helps confirm exactly where those ice sheets exist on the red planet.

When can we go?

Scientists and engineers have long-thought that ice could be a boon for human exploration of the red world.

NASA and other organizations hoping to send people to Mars want to harvest as many resources from the planet itself as possible in order to limit the amount of stuff they would need to send from Earth off to Mars.

“There has been discussion by the Mars Exploration Program Analysis Group… and others in the community of using ice as a resource,” lead author and planetary scientist Colin Dundas, said via email. “Our research may be useful information but it will be up to them to determine how to use it.”

If there is a relatively large cache of ice just under the Martian surface, as this study — which is based on data from the Mars Reconnaissance Orbiter (MRO) — suggests, it could help any future explorers who would want to use utilize it fuel or even just water.

“In many ways, water is the key resource: Humans need liquid water biologically, water can be processed to provide oxygen for breathing and hydrogen for energy generation and even rocket fuel. Water ice deposits may be that resource,” Richard Zurek, the chief Mars scientist at NASA’s Jet Propulsion Laboratory, said in an email.

“… The question is how much energy/work does it take to extract the water, to transport it to where the humans are and then to process it?”

That said, it may not be all that easy to access the ice found in the new study.

According to Zurek, who is an MRO project scientist but did not participate in the new study, the newly-identified sites with water-ice are in the higher latitudes of Mars, meaning that sunlight and temperatures in those areas go through extreme swings throughout the year.

This could make it more difficult for a human explorer to extract those resources, Zurek said.

Ice sheets on Mars

But how did that water-ice get there in the first place?

The new study suggests that the ice built up over time, much the same way that Earth’s glaciers and ice sheets came to be.

Here’s how it works on Mars: When the planet is farther from the sun in its orbit, and it snows, that snow remains on the surface and becomes a buildup of ice.

Over time, what first began as snow is “compacted into massive, fractured, and layered ice,” the study says. Some of that ice was then covered up by the movement of dirt on the surface of the planet, saving it from sublimating — turning straight from a solid into gas.

Aside from potentially aiding in human exploration of Mars, the newly-mapped ice sheets could also unlock secrets hidden in Mars’ past.

“We expect the vertical structure of Martian ice-rich deposits to preserve a record of ice deposition and past climate,” the study says.

Kolibree Magik toothbrush lets kids play with augmented reality while they brush

artificial intelligence 5291510 1920

Augmented reality is slowly seeping into our everyday lives. It’s not just for snaps and video games anymore. Case in point: a new kids toothbrush with AR.

French company Kolibree announced at CES 2018 a smart toothbrush that uses AR to make brushing teeth fun for kids.

The device is paired with a motion-tracking app that uses your smartphone’s front-facing camera to put your kid right in the middle of the fun. It comes with a phone stand, so your kids don’t have to worry about holding up a phone while they brush.

Kids can choose from 15 different games, featuring pirates, princesses, monsters, and a whole cast of fantasy characters.

In one version, kids are tasked with shooting a monster who is spreading cavities across the land. As it runs around the screen, the child in turn moves the toothbrush around her mouth to shoot it.

The toothbrush also allows parents to monitor their children’s brushing habits. They’ll see how many times a day their kids are brushing, how fast, and for how long.

Oh, and you don’t need to stress about over-brushing: The app can only be used three times per day.

Another interesting feature: It teaches kids to brush. The Magik toothbrush app offers kids guidance on where to brush, how thoroughly to brush, and how long to stay in each spot.

This is not Kolibree’s first go at a smart toothbrush. The company released Ara, a toothbrush that uses artificial intelligence to track oral health and encourage healthy brushing habits, in early 2017.

Magik will launch later this year for under $30. That’s significantly more than your average toothbrush, but you get the brush, the mobile game, the stand, and a much happier kid for that price.

Cold snaps like the one that just gripped the U.S. are far more rare thanks to global warming

artificial intelligence 5291510 1920

The first week of January was the coldest such week on record in most locations in the Eastern United States. It was so frigid that week, and the week preceding it, that sea ice formed around Cape Cod and Chesapeake Bay, sharks froze to death on Massachusetts beaches, and alligators went into a resting state while entombed in ice.

One might think that a cold snap like this one all but disproves global warming, or at least refutes the more dire scenarios about winter all but disappearing as the globe responds to sharp increases in greenhouse gases, such as carbon dioxide and methane.

However, the reality is far more complex, scientists say. In fact, it’s getting harder to pull off a cold outbreak of the severity and longevity of the late December and early January Arctic blast, according to a new analysis published on Thursday.

The study, by the World Weather Attribution project, an international consortium of researchers that analyze the role global warming may have played in extreme events, concludes that a cold outbreak like the one that just occurred is 15-times less likely to take place today due to global warming.

Scientists from Princeton University, the Royal Netherlands Meteorological Institute, University of Oxford, and Climate Central examined the two-week cold wave, between Dec. 26, 2017 and Jan. 8, 2018, over the northeastern U.S. and southeastern Canada. They found that this was a “relatively rare event” now that global warming has made such cold snaps less frequent and severe.

In fact, the attribution analysis, which has not yet been peer-reviewed, found that the effects of global warming on cold outbreaks like this is to make them warmer than they otherwise would be, by about 4 degrees Fahrenheit.

Trend in the coldest two weeks of the winter as a multiple of the global mean temperature rise during the 1880 to 2017 time period.

For the study, scientists compared the temperatures during the cold wave to readings during the past 30 years, as well as the time series of the temperature of the coldest two weeks of the year, dating back to 1880. They found that there were many equally cold or colder two-week periods in this region in the past, but none have occurred since the winter of 1993-94.

“Cold waves like this occurred more frequently in the climate of a century ago and the temperature of two-week cold waves has increased throughout North America, which is consistent in a climate of global warming,” said Geert Jan van Oldenborgh, senior researcher at the Royal Netherlands Meteorological Institute (KNMI), in a press release.

Many records were broken during this cold snap, with the most frigid conditions found on the back side of the “bomb cyclone” that slammed the East Coast with snow and high winds on Jan. 3 through 5. New York City’s temperature remained at or below 32 degrees Fahrenheit for two weeks, which ranks among the top five records for the most consecutive number of days at or below freezing. Chicago’s 12 consecutive days below 20 degrees Fahrenheit tied a record seen only twice before in 1895 and 1936

The study’s findings are likely cold comfort to the millions who just experienced bone-chilling conditions, though. But they are important, since they show how winter cold spells are changing as the climate warms.

Temperature of the coldest two-week period averaged over land points in 40º–50ºN, 65º–95ºW. The green line is a 10-year running mean.

The scientists found that the temperature of the coldest two-week period has increased about two times faster than the global mean temperature has increased. In other words, the coldest periods are warming faster than the overall warming rate, making cold extremes less severe and more rare.

In fact, the researchers calculated that a cold wave like this occurred about once every 17 years at the beginning of the 20th century, but now can be expected to occur just once out of every 250 years.

While some scientists contend that melting Arctic sea ice is causing colder air to leak southward into the midlatitudes during the winter, thereby intensifying winter weather in the U.S. and Europe, this study argues against that.

The researchers found that the weather pattern that caused the two-week cold period has not been occurring more frequently lately.

In any case, winter has only just started. While the odds of another cold snap of similar severity are long, they’re not zero. So keep that heavy coat and long underwear handy for a little longer.

Girl plays ‘Star Wars’ Cantina theme with a pencil, is groundbreaking math genius

artificial intelligence 5291510 1920

What you’re about to watch is the work of a name you should remember: Dani Ochoa.

Dani, who characterizes herself as “a girl with too much time on her hands” is also, apparently, a goddamn math genius.

She figured out how to play the Mos Eiseley Cantina theme from “Star Wars.”

With a pencil.

While writing.

While writing a coherent and apparently working math equation.

And not just a working math equation. But a working math equation that produces, yes, the number of the speed of light.A sampling of crowdsourced math-checked, via the Reddit Video thread, found this:

…These letters are actually common variables found in physics!

v commonly stands for velocity

V stands for voltage

E stands for Young’s Modulus, which is the measure of a solid materials stiffness

f stands for friction

A is peak amplitude

This is where things really start to get crazy. If we can extrapolate that this formula has something to do with the Star Wars universe, then perhaps it might has something to do with space travel (since, you know, that is one of the major themes of the universe right?).

Currently, space shuttles that leave Earth travel at approximately 17,500 miles p—

Yeah, look, we work for a website, half this industry barely squeaked by Algebra 2—we don’t know if the math actually checks out, but sure as hell sounds legit.

Anyway, bottom line, here: Dani Ochoa deserves a MacArthur Grant. With a little more time on her hands, she’s gonna send us into the fifth dimension and find a new planet where we can live. There, phrases like “Steve Bannon” don’t exist. All hail.

2018 just started but ‘Fire and Fury’ may already be the shadiest book of the year

artificial intelligence 5291510 1920

We’re only two weeks into 2018 but it’s impossible to talk about books in the new year without hearing three words: fire and fury.

Since an excerpt published in New York Magazine on Jan 3., the country has been buzzing about columnist and non-fiction author Michael Wolff’s latest book Fire and Fury: Inside the Trump White House.

The book is a searing deep dive into Donald Trump’s presidency as seen from Trump’s own White House staff, most notably Trump’s former chief strategist Steve Bannon (who, since the publication of Fire and Fury, has been disavowed by the Trump campaign and ousted from Breitbart News) and former White House deputy chief of staff Katie Walsh.

But whether Wolff is dragging his subjects, like when Michael Wolff tries to explain a theory of why Donald Trump might try to court Vladimir Putin:

But then there was the those-that-know-him-best theory, some version of which most Trumpers would come to embrace. He was just star-fucking. He took his beauty pageant to Russia because he thought Putin was going to be his friend. But Putin couldn’t have cared less, and in the end Trump found himself at the promised gala dinner seated on one side next to a guy who looked like he had never used a utensil and on the other side Jabba the Hutt in a golf shirt. In other words, Trump—however foolish his sucking-up might have been, and however suspicious it might look in hindsight—just wanted a little respect.

or roasting Donald Trump’s hair

[Ivanka] often described the mechanics behind it to friends: an absolutely clean pate — a contained island after scalp-reduction ­surgery — surrounded by a furry circle of hair around the sides and front, from which all ends are drawn up to meet in the center and then swept back and secured by a stiffening spray. The color, she would point out to comical effect, was from a product called Just for Men — the longer it was left on, the darker it got. Impatience resulted in Trump’s orange-blond hair color.”

one thing becomes abundantly clear about Fire and Fury: nothing and no one is safe from a Michael Wolff’s shady, shady pen.

This week on the MashReads Podcast, we chat about Michael Wolff’s Fire and Fury. Join us in the episode above as we chat about what this book says about the Donald Trump presidency, how do we separate fact vs. fiction in this book given Michael Wolff’s somewhat dubious fact-checking methods, and what to make of the president’s response to Fire and Fury.

And as always, we close the show with recommendations:

  • Peter recommends The Mighty Boosh, a BBC Three comedy. “It’s just the weirdest and most surreal show, that’s slightly problematic sometimes. All that said, though, it’s a delightful show because it has my two favorite comedians: Rich Fulture and Matt Berry. It’s fun. It’s on Hulu.”

  • Heather recommends “The Liars Club” by Mary Karr. “Mary Karr is perfect, she’s never made a mistake, much like Michael Wolff. This published in ’96 or ’97, and it kicked off the era of memoir writing. This was like the original good memoir.”

  • MJ recommends author Matt De La Peña’s essay for TimeWhy We Shouldn’t Shield Children From Darkness.” “The essay is just so movign about how we need to support children through darkness and the incredible, heartbreaking moments that he’s expereicend when he’s gotten to see a child expressing true emotion and grappling with that.” He also recommends RnB singer Jessie Reyez. “Her songs just got me all up in my feelings.”

Actress Mira Sorvino apologizes for working with Woody Allen

artificial intelligence 5291510 1920

Actress Mira Sorvino penned an open letter Thursday apologizing to Dylan Farrow, daughter of filmmaker Woody Allen, for ignoring the sexual assault allegations Farrow made against her father and working with him in the ’90s.

Sorvino worked with Allen on the 1995 film Mighty Aphrodite, a few years after Farrow (who was 7-years-old at the time) alleged that Allen has sexually assaulted her. Recently, Farrow has become more outspoken about Allen’s alleged actions, calling out actors who have worked with him after the allegations went public.

Farrow’s call to action prompted Sorvino to write an apology for working with Woody Allen, via The Huffington Post, saying that she now believes Farrow’s accusations.

Sorvino wrote that, when she worked with Allen, she did not put much stake into Farrow’s allegations, something that she now regrets and apologizes for.

I am so sorry, Dylan! I cannot begin to imagine how you have felt, all these years as you watched someone you called out as having hurt you as a child, a vulnerable little girl in his care, be lauded again and again, including by me and countless others in Hollywood who praised him and ignored you. As a mother and a woman, this breaks my heart for you. I am so, so sorry!

We are in a day and age when everything must be re-examined. This kind of abuse cannot be allowed to continue. If this means tearing down all the old gods, so be it. The cognitive dissonance, the denial and cowardice that spare us painful truths and prevent us from acting in defense of innocent victims while allowing “beloved” individuals to continue their heinous behavior must be jettisoned from the bottom of our souls. Even if you love someone, if you learn they may have committed these despicable acts, they must be exposed and condemned, and this exposure must have consequences. I will never work with him again.

Shortly after Sorvino’s letter was published, Farrow gave her a heartfelt thank you on Twitter.

@MiraSorvino, I am overwhelmed and my gratitude to you cannot be expressed sufficiently in words. This letter is beautiful and I will carry your words with me. Your courage has been boundless and your activism an example for us all. From the bottom of my heart, thank you. https://t.co/8U73mb2twD

— Dylan Farrow (@realdylanfarrow) January 11, 2018

Sorvino’s open letter comes about a day after Lady Bird writer and director Greta Gerwig wrote a similar statement in which she expressed regret for working with Allen on the 2012 film To Rome with Love. Farrow thanked Gerwig as well.

Greta, thank you for your voice. Thank you for your words. Please know they are deeply felt and appreciated. https://t.co/q7dV2yAFwH

— Dylan Farrow (@realdylanfarrow) January 10, 2018

There are still many people who have worked with Allen in recent years who have not spoken publicly about Allen, despite the recent wave of support for women and men in Hollywood coming forward against men with allegations of sexual harassment and misconduct.

Some genius made Tide Pod sushi you can actually eat

artificial intelligence 5291510 1920

For better or for worse, a lot of people on the internet think Tide Pods look delicious. For better or for worse, I am one of them.

So I was thrilled to see that according to r/food, a friend of Redditor dweron appears to have successfully made edible Tide Pods in sushi form — a feat I am now affectionately calling “the dream.”

To be clear, this isn’t the first time the topic of edible Pods has been broached online. There’s been a hypothetical recipe floating around for a few days now. But that one — let’s be honest — seems pretty flavorless, and this one looks a little more appetizing. It even appears to have retained that iconic Tide Pod squish.

A forbidden snack forbidden no more? Perhaps. But if sushi-making isn’t your forte, you (and I) should probably stick to gazing longingly at photos of Tide Pods instead.

If you’re a frequent traveler, you know how annoying it can be to wait for your checked luggage to come around the carousel. On the flip side, we’ve all been there when someone tried to fit their giant suitcase in the overhead bin and that’s not fun for anyone.

Finding the perfect carry on is tricky — they have to keep up with you and fit your specific traveling style. Are you the type of person who needs to plan every stop of your trip? Or are you more of a wanderer who lets the road take them where it may? Whatever end of the travel spectrum you fall on, your suitcase is your most important accessory. You need to make sure you have the right one for your lifestyle.

We’ve rounded up five of our favorite carry-on bags that fit most airlines’ specifications for overhead luggage. (As always, you’ll want to make sure to check your airline’s requirements before you fly.) Whether you’re an old-school business traveler or a wanderlust-filled backpacker, we know you’ll find the perfect travel companion.

For the traditionalists — Delsey Spinner Trolley

This sleek hardshell case is made of a sturdy plastic that’s still lightweight enough to lift into an overhead compartment. Plus, the high-gloss finish looks like something out of Mad Men. It comes with dual-spinner wheels, a compression compartment, and TSA-approved lock that are pretty standard on nicer luggage.

For the trendsetters — Away Carry-On

The internet has been going crazy about Away, the luggage startup with tons of neat features. One of the most hyped perks is the TSA-approved battery pack that lets you juice your devices on the go. Equally useful, if not as exciting, is the included compressible laundry bag that keeps your dirty clothes separated from clean ones.

For the hyper-organized — Genius Pack

If you love making itineraries and have your iPad out wherever you go, the Genius pack is as coordinated as you are. A packing checklist is printed on the inside of your case and each pocket is labelled for its particular use. There’s external pockets for magazines, water bottles, passports, and a strap to hold your jacket. Plus you can grab an add-on battery pack or umbrella that fit right into their own compartments.

For the backpackers — Osprey Packs

When the airplane is only the first part of your journey, packing can be annoying. You want to make sure everything is kosher for the TSA, but durable enough for more intense parts of the journey. Osprey’s travel backpack fits the bill on both counts. The backpack straps are padded with a sternum strap and hip belt. When you need to condense things for the plane, the straps are easily stowed in their own pocket. A protected laptop pocket gives you easy access to electronics during security screenings and the compression straps ensure that your bag will fit in the overhead bin.

For the hyper-organized backpackers — eBags

Combining the versatility of a backpack with the compartmentalization of a carry-on, eBags’ MotherLode Convertible is the best of both worlds. The inner compartments are modular, with a removable divider and compression to keep contents secure. A roomy top pocket gives you easy access to the things you’ll need frequently, while the hidden laptop pocket is accessible while remaining discreet. There’s even a collapsible water bottle pocket for when you need to hydrate on the go.

Disney shows you how to make a Porg bento box from ‘The Last Jedi’

artificial intelligence 5291510 1920

There’s now a how-to video on making a Porg bento box and we are eating it up.

Disney Parks made a how-to video on how to make a Porg bento box. It’s fun and easy, as long as the Jawas don’t keep interrupting.

Using primarily rice, sesame seeds, olives and soy sauce, the chef makes an almost identical sushi-version of the beloved Porg, from Star Wars Episode VIII: The Last Jedi.

Even as sushi it’s cute.

Though this is adorable, something still feels wrong about eating a Porg, especially after that Chewy scene in The Last Jedi. Still, eating a sushi Porg is better than a real Porg.
