When Nuns Meet Sports
by Jason Plautz

Athletes are rarely shy about their religion, whether they're dedicating their MVP award to God or crossing themselves before stepping to the plate. But still, organized religion generally stays out of sports. After all, when's the last time you saw the Pope and his cardinals go shirts and skins for some pick-up hoops?

Still, I've found that nuns have surprisingly strong ties to athletics. Many hometown nuns cheer on their favorite sports teams, but here are four more ways sisters and sports meet. And I promise I won't use the "nun/none" pun once.

Running Triathlons

Sister Madonna Buder from Spokane has completed 37 marathons, 300 triathlons and 31 Ironman Triathlons. And she didn't even start until she was 50. She first started competing because a family member was battling alcoholism, so she thought she could transfer her will to overcome to the ones in need. Buder takes a distinctly religious approach to running, envisioning the finish line as the Pearly Gates and talks about the angels that once cushioned her nasty fall during the biking portion of a triathlon. The 70-something nun holds her own in the grueling Ironman triathlon and says she trains by running or biking to mass every day.

Providing Super Bowl Lodging

With tickets costing upwards of a thousand dollars, Super Bowl spectators this year didn't have much extra cash to spend on lodging. Enter the Our Lady of Guadalupe monastery, which offered ten rooms at a mere $250 a night with an additional $50 for each extra guest. The sisters hosted both Patriots and Giants fans and offered rather plush accommodations. The monastery was tricked out with a flat-screen TV, a kitchen and a fridge stocked with snacks and sodas. Drinking and smoking wasn't allowed (natch), but the sisters said the location was ideal because it was only three miles away from the University of Phoenix Stadium, but tucked away in a residential neighborhood that allowed guests to stay out of the hubbub surrounding the big game.

Prognosticating

The Chicago native correctly picked the Bears to win the 1986 Super Bowl and since then has picked 17 of 22 Super Bowl winners. But she doesn't just have a good track record, she also adds a touch of class to the picks by writing poems about each projected winner (read her poem about the 2007 Patriots here). She's been off the last three years, wrongly choosing the Seahawks, Bears and Patriots, but she still sticks by her picks.

Managing Race Horses

Back in 2005, the nuns of New York's Little Sisters of the Poor order received a six-month-old horse as a donation. Rather than raising it, they decided to auction the filly, which they christened Poor Little Sister, off. The auction was a success, but when bidding stalled at $5,000, one of the nuns started upping the bids to make sure they'd net a good amount of money. The horse ended up going for $8,000 and the nuns received 20 percent of the horse's winnings.

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!

200 Health Experts Call for Ban on Two Antibacterial Chemicals
June 21, 2017

In September 2016, the U.S. Food and Drug Administration (FDA) issued a ban on antibacterial soap and body wash. But a large collective of scientists and medical professionals says the agency should have done more to stop the spread of harmful chemicals into our bodies and environment, most notably the antimicrobials triclosan and triclocarban. They published their recommendations in the journal Environmental Health Perspectives.

The 2016 report from the FDA concluded that 19 of the most commonly used antimicrobial ingredients are no more effective than ordinary soap and water, and forbade their use in soap and body wash.

"Customers may think added antimicrobials are a way to reduce infections, but in most products there is no evidence that they do," Ted Schettler, science director of the Science and Environmental Health Network, said in a statement.

Studies have shown that these chemicals may actually do more harm than good. They don't keep us from getting sick, but they can contribute to the development of antibiotic-resistant bacteria, also known as superbugs. Triclosan and triclocarban can also damage our hormones and immune systems.

And while they may no longer be appearing on our bathroom sinks or shower shelves, they're still all around us. They've leached into the environment from years of use. They're also still being added to a staggering array of consumer products, as companies create "antibacterial" clothing, toys, yoga mats, paint, food storage containers, electronics, doorknobs, and countertops.

The authors of the new consensus statement say it's time for that to stop.

"We must develop better alternatives and prevent unneeded exposures to antimicrobial chemicals," Rolf Haden of the University of Arizona said in the statement. Haden researches where mass-produced chemicals wind up in the environment.

The statement notes that many manufacturers have simply replaced the banned chemicals with others. "I was happy that the FDA finally acted to remove these chemicals from soaps," said Arlene Blum, executive director of the Green Science Policy Institute. "But I was dismayed to discover at my local drugstore that most products now contain substitutes that may be worse."

Blum, Haden, Schettler, and their colleagues "urge scientists, governments, chemical and product manufacturers, purchasing organizations, retailers, and consumers" to avoid antimicrobial chemicals outside of medical settings. "Where antimicrobials are necessary," they write, we should "use safer alternatives that are not persistent and pose no risk to humans or ecosystems."

They recommend that manufacturers label any products containing antimicrobial chemicals so that consumers can avoid them, and they call for further research into the impacts of these compounds on us and our planet.
