Feel Art Again: "A Virgin"

Original image


Abbott Handerson Thayer is an American artist known for his paintings of ethereal angels as well as his camouflage techniques. "A Virgin," one of his paintings of his children, is part of the collection at the Freer Gallery of Art, one of the Smithsonian museums. Today we'll delve into this haunting painting.

1. Abbott Thayer was married to Kate Bloede, whose family introduced him to the romantic world of the arts. When her father died, she became severely depressed and died a short time after, in 1891. Her death hit Thayer hard and significantly impacted his work, as his paintings took on a less cheery tone. "A Virgin" was begun shortly after her death.

2. The central figure is Thayer's oldest daughter, Mary. He originally modeled her after Flora, the Greek goddess of flowers, but decided to paint her as a Greek "Victory" figure. His depiction of Mary was inspired by the Winged Victory of Samothrace, a Hellenistic sculpture, and the Sherman Monument, a winged female figure leading the Union commander into battle, which was sculpted by Augustus Saint-Gaudens, a friend of Thayer.

3. Beginning at a young age, Thayer was an amateur naturalist. After he moved to Mount Monadnock in New Hampshire, he worked to protect the trees on Monadnock and founded the Thayer Fund, which paid for the protection of bird sanctuaries. He described himself as "bird crazy."

4. Both his interest in nature as well as his interest in color prompted his study of protective coloration in nature. With his son, Gerald (pictured in "A Virgin"), he wrote Concealing Coloration in the Animal Kingdom (1909). The book became the basis for American camouflage techniques during World War I. Thayer became known as the "father of camouflage." In 1902, he even obtained a patent, with his friend and fellow artist George de Forest Brush, for their idea to use protective coloration on American ships. Patent No. 715,013 is titled "Process of Treating the Outsides of Ships, etc., for Making Them Less Visible."

5. Thayer suffered from what he called "the Abbott pendulum," bipolar disorder. He referred to the two extremes as "all-wellity" and "sick disgust." The symptoms worsened during controversy over his camouflage findings; Theodore Roosevelt was one of the critics who denounced Thayer's camouflage theories.

6. By the time he died in 1921, Abbott Thayer had lived in the colony on Mount Monadnock for 20 years. After his death, his son Gerald scattered Thayer's ashes on Mount Monadnock.

Large versions of "A Virgin" are available through the Freer Gallery and Wikipedia.

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!

What Happened to Jamie and Aurelia From Love Actually?

Fans of the romantic-comedy Love Actually recently got a bonus reunion in the form of Red Nose Day Actually, a short charity special that gave audiences a peek at where their favorite characters ended up almost 15 years later.

One of the most improbable pairings from the original film was between Jamie (Colin Firth) and Aurelia (Lúcia Moniz), who fell in love despite almost no shared vocabulary. Jamie is English, and Aurelia is Portuguese, and they know just enough of each other’s native tongues for Jamie to propose and Aurelia to accept.

A decade and a half on, they have both improved their knowledge of each other’s languages—if not perfectly, in Jamie’s case. But apparently, their love is much stronger than his grasp on Portuguese grammar, because they’ve got three bilingual kids and another on the way. (And still enjoy having important romantic moments in the car.)

In 2015, Love Actually script editor Emma Freud revealed via Twitter what happened between Karen and Harry (Emma Thompson and Alan Rickman, who passed away last year). Most of the other couples get happy endings in the short—even if Hugh Grant's character hasn't gotten any better at dancing.
