The 65 Year Battle over the Deceased Wife's Sister's Marriage Act

Library of Congress

Until 1907, it was illegal in England for a man to marry the sister of his dead wife. That kind of marriage had been made explicitly illegal in 1835 when Parliament passed a bill designed to protect the inheritance of the son of a Duke who had married his dead wife's sister. In-laws had been marrying each other for a long time, but those marriages were considered "voidable," if anyone wanted to challenge them. The 1835 bill said that that the marriages that had already happened could no longer be voided (the Duke's son would get his due!), but from then on, no more marrying your dead wife's sister.

Parliament had to tack that part on to get the bill to pass. In the social climate of the time it was "too soon" to eliminate the taboo on in-law marriage in one fell swoop. When the more progressive bill to legalize wife's sister marriage was finally introduced in 1842, a fight broke out that would last 65 years.

What was the big deal? Opponents of the bill saw it as a slippery slope that would lead to the legalization of all kinds of incest. They drew arguments from the Bible: Genesis 2 states that husband and wife "became one flesh," therefore your wife's sister was really your own sister. Leviticus prohibits a man from uncovering "the nakedness of thy brother's wife," and so, by analogy, he shouldn't do it to his wife's sister either. Arguments from science included the bizarre claim that married couples become blood relations through some biological consequence of sexual intercourse, or that the idea that in-law marriage was wrong came from evolutionary instinct. People also thought it would destroy the family by encouraging husbands and their wives' sisters to lust after each other while the wives were still alive.

Were there really so many brothers- and sisters-in-law who wanted to get married? Not really, but it was more common than it is now. Women often died in childbirth, and their unmarried sisters, who had few other options to support themselves besides marriage, would step in to care for the family. For convenience, and sometimes developing love, remarriage seemed like the thing to do. Supporters of the act argued that prohibiting these marriages was unfair to the poor, who could not afford to hire help and could not travel out of the country to get married, as the upper class often did to get around the law.

The Deceased Wife's Sister's Marriage Act finally passed in 1907. By that time, the prohibition had long been lifted in most of Europe, the United States and the colonies. At the same time, society was changing in a way that meant fewer women were dying in childbirth and single women had more opportunities to support themselves. Not as many people wanted to make this kind of marriage. But if they did, they finally had freedom to choose it. After registering a few sputtering complaints, opponents of the bill got used to it too, and the world continued to spin.

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?
May 26, 2017

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.
