Ask an anatomist, and they’ll be able to tell you that your kneecap is really your patella. Your armpit is your axilla and the little groove above your top lip is your philtrum. The little flap of cartilage the covers the hole in your ear? That’s your tragus, named after the Greek word for a billy goat—because the tuft of hair that grows on it resembles a goat’s beard (apparently).

But if that’s what’s on the outside, what about what happens on the inside? Well, it turns out the English language has quite a rich collection of formal, medical, and old fashioned words for all of the reflexes and reactions that our bodies naturally carry out without a second thought from us. So the next time you’re stretching as you get out of bed, or you interrupt an important meeting with a ructus or a borborygmus, you’ll at least have the perfect word for it.

1. BORBORYGMI

Derived originally from an onomatopoeic Greek word, a borborygmus is a rumbling in the stomach or bowels. Borborygmi are produced as the contents of the intestines are pushed along by waves of muscle contractions called peristalsis, although trapped gas from digested food or swallowed air can also cause your borborygmi to become noisier than normal. Bonus fact: Queasy stomach rumbles were called wambles in Tudor English, and you’d be wamble-cropped if you weren’t feeling well.

2. CACHINNATION

A study in 2013 found that when people laugh, it's only because they've found something funny about 20 percent of the time. The rest of time, we use laughter as a means of signaling things like agreement, affection, ease, and nostalgia that we evolved long before communication through language was possible. And a fit of spontaneous, uproarious, unrestrained laughter is called cachinnation.

3. CICATRIZATION

Cicatrization is the formation of a cicatrix, or a scar. More generally, it refers to any of the healing and sealing processes that help a wound to mend, including the formation of a scab.

4. DEGLUTITION

Deglutition is the proper word for the action of swallowing. It’s an etymological cousin of words like glut, glutton, and gullet.

5. DIAPHORESIS

Sweating has been known by a whole host of (ironically quite beautiful) words in history, including the likes of resudation, sudorification, and diaphoresis, a 17th century word that literally means “to carry through.” Nowadays, "diaphoresis" is rarely encountered outside of purely medical contexts, where it’s used as an older or more formal name for excessive perspiration—a condition better known as hyperhidrosis.

6. ERUCTATION

As well as being another word for a volcanic eruption, eructation is the medical name for burping, while the burp itself is called a ructus. For what it’s worth, the Romans knew excessive or unstoppable belching as ructabundus (although sadly that word has yet to catch on in English).

7. FLATUS

So if a ructus is a burp, no prizes for guessing that a flatus goes the other way. Technically though, flatus is just the build up of gas in the stomach or bowels, not the actual expulsion of it. For that, why not try using an old Tudor English word for a fart—ventosity.

8. HORRIPILATION

Horripilation literally means “bristled hairs,” and is the proper name for what you probably know as gooseflesh or goose bumps. Another name for the same thing is piloerection, although that also includes the phenomenon of animals raising their hair or fur (or, in the case of porcupines, their quills) when they’re stressed or under attack.

9. LACHRYMATION

Lachrymation is the proper name for shedding tears, which are produced in the lachrymal glands above the outer edges of the eyes and are stored in a lachrymal sac on either side of the bridge of the nose. And if you want to get really technical, there are three different types of tears: basal tears, which are constantly produced to keep the surface of the eyes moist; reflex tears, which are the extra tears produced when something enters or irritates the eye; and psychic tears, which are those produced as a response to a mental or emotional stimulus.

10. MASTICATION

Mastication is the proper name for chewing. Etymologically, it’s descended from a Greek word literally meaning “to gnash your teeth,” and is related both to mandible and papier-mâché (which is literally “chewed paper” in French).

11. NICTITATION

Nictitation is the proper name for blinking or winking, and comes from an old pre-Latin word meaning “to incline or bend together,” just as the eyelids do. That twitching muscle in your eyelid after you’ve strained your eyes? That’s a blepharospasm.

12. OBDORMITION

Obdormition is the proper name for sleeping, but it’s usually only used in reference to the feeling of numbness, caused by pressure on a nerve, when a limb or muscle “falls asleep.” Pins and needles, incidentally, is properly called paraesthesia.

13. PANDICULATION

Pandiculation is essentially a catchall term for all those things you do when you’re tired or just waking up, like yawning, stretching your arms and legs, and cracking your joints. Monday morning, in other words.

14. RHINORRHOEA

When your nose runs, that’s rhinorrhoea. Except when you’re having a nosebleed, which is called epistaxis.

15. SINGULTUS

In Latin, singultus was speech interrupted by sobbing, or an inability to speak caused by crying. Based on this, English borrowed the word singult in the 16th century for a single sob, while in the sense of something spasmodically interrupting your speech, and singultus came to be used as a more formal name for hiccups.

16. STERNUTATION

A sneeze or a sneezing fit is properly called a sternutation. Anything described as sternutatory causes sneezing.

17. TUSSICATION

Tussis is the Latin word for “cough.” It’s the origin of both tussication, a formal word for coughing, and pertussis, the medical name for whooping cough.

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

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!

Here's How to Change Your Name on Facebook

Whether you want to change your legal name, adopt a new nickname, or simply reinvent your online persona, it's helpful to know the process of resetting your name on Facebook. The social media site isn't a fan of fake accounts, and as a result changing your name is a little more complicated than updating your profile picture or relationship status. Luckily, Daily Dot laid out the steps.

Start by going to the blue bar at the top of the page in desktop view and clicking the down arrow to the far right. From here, go to Settings. This should take you to the General Account Settings page. Find your name as it appears on your profile and click the Edit link to the right of it. Now, you can input your preferred first and last name, and if you’d like, your middle name.

The steps are similar in Facebook mobile. To find Settings, tap the More option in the bottom right corner. Go to Account Settings, then General, then hit your name to change it.

Whatever you type should adhere to Facebook's guidelines, which prohibit symbols, numbers, unusual capitalization, and honorifics like Mr., Ms., and Dr. Before landing on a name, make sure you’re ready to commit to it: Facebook won’t let you update it again for 60 days. If you aren’t happy with these restrictions, adding a secondary name or a name pronunciation might better suit your needs. You can do this by going to the Details About You heading under the About page of your profile.
