What Happened to Marie Antoinette's Children?

The tragic tale of Marie Antoinette's death during the French Revolution is the stuff of legend. But while the story of Marie Antoinette ends with her beheading in 1793, the tragedy of her family continued to unfold long after her death.

Marie Antoinette and her husband, the Dauphin, were married for seven years before consummating their marriage -- much to the chagrin of Marie's family, particularly her critical mother, the Empress Maria Teresa of the Holy Roman Empire. Marie's place in the royal household of France and Franco-Austrian relations absolutely depended on her producing a male heir, even before her husband became the King of France in 1774. Despite the rocky start, Marie and Louis XVI would have four children -- only one of whom lived to adulthood.

Marie Antoinette's first child was a girl, named Marie Thérèse after Marie's mother. When she was born on December 9, 1778, Marie Antoinette suffered a convulsive fit and collapsed, not surprising after 12 hours of labor in her stuffy room and the possibly dangerous incompetence of her doctor. The Queen wasn't informed the sex of the child until hours later. But when she woke, she reportedly said, "Poor little girl, you are not what was desired, but you are no less dear to me on that account. A son would have been property of the state. You shall be mine." There certainly would have been witnesses to the episode: Court custom at the time dictated that queens gave birth in full view of their courtiers.

Louis Joseph, the King's male heir and the next Dauphin of France, was born three years later, followed by Louis Charles in March of 1785 and Sophie in July of 1786. But Sophie, who was born premature, died just a month shy of her first birthday, and Louis Joseph, who'd been a delicate child most of his life, died two years later, at the age of 7, likely from tuberculosis.

Revolution

While Marie was fulfilling her wifely duties and setting fashion trends in the court at Versailles, France was starving. While Louis XVI continued to send money abroad to support the Americans in the American Revolution, France's national debt exploded; taxes grew, settling most unfairly on the poor; and rampant unemployment combined with poor crops meant that by the late 1780s, France was a powder keg of dissension, anger and resentment. And Marie, with her courtly ways, detached Austrian air, and unfortunate proclivity for spending masses of money, became the scapegoat.

On July 14, 1789, the fuse was lit with the storming of the Bastille; by October, Marie, her husband and her two surviving children were removed from Versailles and moved to the Tuileries in Paris, placed under house arrest. In 1792, the King was deposed and the family was imprisoned in the Temple in Marais.

Louis XVI was executed on January 21, 1793; Marie followed 10 months later, on October 16. On June 8, 1795, their son, the Dauphin and the boy royalists had named Louis XVII, died at the age of 10, most likely of tuberculosis exacerbated by his brutal prison conditions.

Marie Thérèse: The Survivor

Now Marie Thérèse, the oldest of Marie Antoinette's children, was a true orphan. Her parents killed, her brothers and sisters all dead, she was left for a time alone in the Temple prison, before being released at the age of 17 in December of 1795. Soon after, she was married to the Duc d'Angoulême, nephew to the new King, the self-styled Louis XVIII, and now heir to the throne of France. As the Duchesse d'Angoulême, however, her life did not improve: Her marriage was an unhappy one and never consummated, the tragic circumstances of her early life had left her bitter and angry, and she was to spend most of her life exiled from France. She had not inherited her mother's famed beauty -- she suffered from bad teeth, a red face, and a rather masculine build -- or her grace, though for a time, as her husband's claim on the throne became even more assured, she bore her mother's title: Madame la Dauphine.

In 1830, Marie Thérèse technically did achieve the title of Queen of France — for about 20 minutes, long enough for her husband the Duc to sign the abdication papers. She died in October 1851, at the age 72, still in exile. In her last testament, she forgave those who'd made her life so miserable, following, she said, the example of her parents.

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.

The best way to say “I love you” in dog? A monthly subscription to BarkBox. Your favorite pup will get a package filled with treats, toys, and other good stuff (and in return, you’ll probably get lots of sloppy kisses). Visit BarkBox to learn more.
