11 Facts Yü Should Know About the Umlaut

Original image

1. The word “umlaut” comes from one of the Brothers Grimm.

Jacob Grimm was not only a collector of fairy tales (along with his brother Wilhelm), but also one of the most famous linguists ever. In 1819 he described a sound-change process that affected the historical development of German. He called it umlaut from um (around) + laut (sound).

2. “Umlaut” is originally the name for a specific kind of vowel mutation.

Technically, “umlaut” doesn’t refer to the dots, but to the process where, historically, a vowel got pulled into a different position because of influence from another, upcoming vowel.

3. Mimicking that mutation process is a great way to learn to pronounce the umlaut.

Try this: make a u sound (an “oo”). Now imagine there’s an i-sound (an “ee”) coming up. Keep your lips completely frozen in u position while you try to say “ee” with the rest of your mouth. You should feel the body of your tongue move forward and up in your mouth. Hold that u sound with your lips though! Good. That’s an ü.

Not working? Trying pinging back and forth: oo-ee-oo-ee-oo-ee-oo-ee … now freeze your tongue position in “ee” and only move your lips back to “oo.”

(Start with “ah” for ä and “oh” for ö.)

4. English was also affected by the umlaut mutation.

Ever wonder why the plural of “mouse” is “mice”? Blame umlaut. Way, way back in a time before English had branched off from other Germanic languages, plurals were formed with an –i ending. So mouse was mus, and mice was musi. That plural –i pulled the u forward into umlaut. Later, the –i plural ending disappeared and a whole bunch of other sound changes happened, but we are left with the echo of that mutated vowel in mouse/mice, as well as in foot/feet, tooth/teeth, and other irregular pairs.

5. Umlauts weren’t always written as dots above a vowel.

Since the Middle Ages, umlauted vowels have been indicated in various ways in German. Before the two-dot version became the standard in the 19th century, it was usually written as a tiny “e” above the vowel, like so:

It is still sometimes written with an e next to the vowel, for example, Muenchen for München, or schoen for schön.

6. Not all umlauts are umlauts.

We rather casually use “umlaut” to mean “two little dots above a letter,” but not all little dots are umlauts. The mark that prevents two adjacent vowels from combining into one syllable is called a “diaeresis” or “trema.” You see it in French (naïve, Chloë, Noël) and in the pages of the New Yorker (coöperate, reëlection). In Spanish it indicates that the u should be pronounced in the combination gu which is usually pronounced as g alone. Sigue is “seegay” but pingüe is “pingway.”

7. How do you alphabetize umlauted vowels? Depends on the language.

In German, the umlaut is ignored for alphabetization purposes, except when it comes to lists of names. Then, ü, ö, and ä are treated like ue, oe, and ae, respectively, so that variations on the same name (Müller, Mueller) will be grouped together. In Swedish and Finnish the umlauted vowels come at the end of the alphabet (…X,Y,Z,Å,Ä,Ö). In Hungarian and Turkish the umlauted vowels follow their non-umlauted counterparts.

8. In Germany, a Big Mac used to be a Big Mäc.

And the Filet-o-Fish was the Fishmäc. The spelling with the umlaut actually gets German speakers a little closer to the English pronunciation of “Mac.” But in 2007 McDonald’s took away the umlauts, and now Germans have to get boring ol’ Big Macs like the rest of us.

9. Epäjärjestelmällistyttämättömyydellänsäkäänköhän

This Finnish word, according to the Guinness Book of Records, is the longest non-compound word in the world. With 12 umlauted letters, it is probably the word with the most umlauts as well. It means something like “questionable this thing being doubtful its non-unsytematization.” Finns don’t even really understand it. But they can just as well get five umlauts in a normal word like kääntäjää (translators). The longest run of consecutive umlauts comes from Estonian: jäääär means “the edge of the ice.”

10. An artificial language full of umlauts became hugely popular in the 1880s.

A German priest named Johann Schleyer invented a universal language he called Volapük. It was based on simplified European roots and was meant to be logical and easy to learn. It was chock-full of umlauts: “love” was löf, “smile” was smül, and “speak” was pük. Many people did learn it, and by 1889 there were over 200 Volapük clubs around the world and 25 Volapük journals. Even people who didn’t learn it had heard of it. But supporters thought it would have a better chance of succeeding internationally if it lost the umlauts. Schleyer refused. He said that “a language without umlauts sounds monotonous, harsh, and boring.” Infighting over umlauts and other proposed reforms led to a schism and, ultimately, to the decline of Volapük.

11. Heavy Metal Umlauts don’t look so heavy metal to umlaut users.

Beginning with Blue Öyster Cult in the early '70s, heavy metal bands started using the umlaut to signal a badass hard rock attitude. To Americans the umlaut had a harsh, Teutonic look to it and Mötley Crüe, Motörhead, Queensrÿche, and dozens of other bands (listed on the Metal Umlaut Wikipedia page) tried to impart a little gothic scariness through randomly scattered pairs of dots. The dots didn’t have quite the same effect in umlaut-using countries, where the umlaut signifies vowel qualities of softness, highness, lightness and roundedness.

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning

Jacques Mattheij made a small, but awesome, mistake. He went on eBay one evening and bid on a bunch of bulk LEGO brick auctions, then went to sleep. Upon waking, he discovered that he was the high bidder on many, and was now the proud owner of two tons of LEGO bricks. (This is about 4400 pounds.) He wrote, "[L]esson 1: if you win almost all bids you are bidding too high."

Mattheij had noticed that bulk, unsorted bricks sell for something like €10/kilogram, whereas sets are roughly €40/kg and rare parts go for up to €100/kg. Much of the value of the bricks is in their sorting. If he could reduce the entropy of these bins of unsorted bricks, he could make a tidy profit. While many people do this work by hand, the problem is enormous—just the kind of challenge for a computer. Mattheij writes:

There are 38000+ shapes and there are 100+ possible shades of color (you can roughly tell how old someone is by asking them what lego colors they remember from their youth).

In the following months, Mattheij built a proof-of-concept sorting system using, of course, LEGO. He broke the problem down into a series of sub-problems (including "feeding LEGO reliably from a hopper is surprisingly hard," one of those facts of nature that will stymie even the best system design). After tinkering with the prototype at length, he expanded the system to a surprisingly complex system of conveyer belts (powered by a home treadmill), various pieces of cabinetry, and "copious quantities of crazy glue."

Here's a video showing the current system running at low speed:

The key part of the system was running the bricks past a camera paired with a computer running a neural net-based image classifier. That allows the computer (when sufficiently trained on brick images) to recognize bricks and thus categorize them by color, shape, or other parameters. Remember that as bricks pass by, they can be in any orientation, can be dirty, can even be stuck to other pieces. So having a flexible software system is key to recognizing—in a fraction of a second—what a given brick is, in order to sort it out. When a match is found, a jet of compressed air pops the piece off the conveyer belt and into a waiting bin.

After much experimentation, Mattheij rewrote the software (several times in fact) to accomplish a variety of basic tasks. At its core, the system takes images from a webcam and feeds them to a neural network to do the classification. Of course, the neural net needs to be "trained" by showing it lots of images, and telling it what those images represent. Mattheij's breakthrough was allowing the machine to effectively train itself, with guidance: Running pieces through allows the system to take its own photos, make a guess, and build on that guess. As long as Mattheij corrects the incorrect guesses, he ends up with a decent (and self-reinforcing) corpus of training data. As the machine continues running, it can rack up more training, allowing it to recognize a broad variety of pieces on the fly.

Here's another video, focusing on how the pieces move on conveyer belts (running at slow speed so puny humans can follow). You can also see the air jets in action:

In an email interview, Mattheij told Mental Floss that the system currently sorts LEGO bricks into more than 50 categories. It can also be run in a color-sorting mode to bin the parts across 12 color groups. (Thus at present you'd likely do a two-pass sort on the bricks: once for shape, then a separate pass for color.) He continues to refine the system, with a focus on making its recognition abilities faster. At some point down the line, he plans to make the software portion open source. You're on your own as far as building conveyer belts, bins, and so forth.

Check out Mattheij's writeup in two parts for more information. It starts with an overview of the story, followed up with a deep dive on the software. He's also tweeting about the project (among other things). And if you look around a bit, you'll find bulk LEGO brick auctions online—it's definitely a thing!

8 Common Dog Behaviors, Decoded
May 25, 2017

Dogs are a lot more complicated than we give them credit for. As a result, sometimes things get lost in translation. We’ve yet to invent a dog-to-English translator, but there are certain behaviors you can learn to read in order to better understand what your dog is trying to tell you. The more tuned-in you are to your dog’s emotions, the better you’ll be able to respond—whether that means giving her some space or welcoming a wet, slobbery kiss. 

1. What you’ll see: Your dog is standing with his legs and body relaxed and tail low. His ears are up, but not pointed forward. His mouth is slightly open, he’s panting lightly, and his tongue is loose. His eyes? Soft or maybe slightly squinty from getting his smile on.

What it means: “Hey there, friend!” Your pup is in a calm, relaxed state. He’s open to mingling, which means you can feel comfortable letting friends say hi.

2. What you’ll see: Your dog is standing with her body leaning forward. Her ears are erect and angled forward—or have at least perked up if they’re floppy—and her mouth is closed. Her tail might be sticking out horizontally or sticking straight up and wagging slightly.

What it means: “Hark! Who goes there?!” Something caught your pup’s attention and now she’s on high alert, trying to discern whether or not the person, animal, or situation is a threat. She’ll likely stay on guard until she feels safe or becomes distracted.

3. What you’ll see: Your dog is standing, leaning slightly forward. His body and legs are tense, and his hackles—those hairs along his back and neck—are raised. His tail is stiff and twitching, not swooping playfully. His mouth is open, teeth are exposed, and he may be snarling, snapping, or barking excessively.

What it means: “Don’t mess with me!” This dog is asserting his social dominance and letting others know that he might attack if they don’t defer accordingly. A dog in this stance could be either offensively aggressive or defensively aggressive. If you encounter a dog in this state, play it safe and back away slowly without making eye contact.

4. What you’ll see: As another dog approaches, your dog lies down on his back with his tail tucked in between his legs. His paws are tucked in too, his ears are flat, and he isn’t making direct eye contact with the other dog standing over him.

What it means: “I come in peace!” Your pooch is displaying signs of submission to a more dominant dog, conveying total surrender to avoid physical confrontation. Other, less obvious, signs of submission include ears that are flattened back against the head, an avoidance of eye contact, a tongue flick, and bared teeth. Yup—a dog might bare his teeth while still being submissive, but they’ll likely be clenched together, the lips opened horizontally rather than curled up to show the front canines. A submissive dog will also slink backward or inward rather than forward, which would indicate more aggressive behavior.

5. What you’ll see: Your dog is crouching with her back hunched, tail tucked, and the corner of her mouth pulled back with lips slightly curled. Her shoulders, or hackles, are raised and her ears are flattened. She’s avoiding eye contact.

What it means: “I’m scared, but will fight you if I have to.” This dog’s fight or flight instincts have been activated. It’s best to keep your distance from a dog in this emotional state because she could attack if she feels cornered.

6. What you’ll see: You’re staring at your dog, holding eye contact. Your dog looks away from you, tentatively looks back, then looks away again. After some time, he licks his chops and yawns.

What it means: “I don’t know what’s going on and it’s weirding me out.” Your dog doesn’t know what to make of the situation, but rather than nipping or barking, he’ll stick to behaviors he knows are OK, like yawning, licking his chops, or shaking as if he’s wet. You’ll want to intervene by removing whatever it is causing him discomfort—such as an overly grabby child—and giving him some space to relax.

7. What you’ll see: Your dog has her front paws bent and lowered onto the ground with her rear in the air. Her body is relaxed, loose, and wiggly, and her tail is up and wagging from side to side. She might also let out a high-pitched or impatient bark.

What it means: “What’s the hold up? Let’s play!” This classic stance, known to dog trainers and behaviorists as “the play bow,” is a sign she’s ready to let the good times roll. Get ready for a round of fetch or tug of war, or for a good long outing at the dog park.

8. What you’ll see: You’ve just gotten home from work and your dog rushes over. He can’t stop wiggling his backside, and he may even lower himself into a giant stretch, like he’s doing yoga.

What it means: “OhmygoshImsohappytoseeyou I love you so much you’re my best friend foreverandeverandever!!!!” This one’s easy: Your pup is overjoyed his BFF is back. That big stretch is something dogs don’t pull out for just anyone; they save that for the people they truly love. Show him you feel the same way with a good belly rub and a handful of his favorite treats.
