You probably know that numismatists study and collect coins and currency, and you may even know that philatelists study and collect stamps. But other groups of collectors have their own less-heralded nouns, too. Here are just a few other words you can break out the next time you meet a collector.

1. Sucrologists

Sucrologists collect those little sugar packets that you see in restaurants.

2. Deltiologists

Deltiologists study and collect postcards. The word comes from the Greek word deltion, the diminutive of deltos, or “writing tablet.”

3. Phillumenists

Phillumenists collect matchbooks and other match-related items. In 2011, phillumenist Steven Smith earned a place in The Guinness Book of World Records for his collection of 1,054,221 matchbox labels from more than 130 countries.

4. Pannapictagraphists

Pannapictagraphists could probably stand to come up with an easier name for their hobby: collecting comic books.

5. Vexillophiles

Vexillophiles collect and display flags.

6. Plangonologist

Remember George Costanza’s doomed fiancée Susan on Seinfeld? She was a plangonologist, or collector of dolls.

7. Velologists

Velologists collect and study expired specimens of the tax discs that British vehicles have been required to display since the beginning of 1921.

8. Arenophiles

Arenophiles collect sand samples from around the world. They particularly prize rare samples of black or green sand from certain beaches.

9 & 10. Tegestologists & Labeorphilists

Tegestologists have a great excuse to spend time in bars since they collect coasters or beermats. They should probably team up with labeorphilists, or collectors of beer bottles.

11. Falerists

Falerists study and collect medals, badges, pins, and other military and civilian awards and decorations.

12. Scutelliphiles

Scutelliphiles are similar to falerists, but they collect souvenir patches and badges.

13. Lotologists

Lotologists collect lottery tickets, both used and unused. In 2006 reports claimed that retired U.S. Navy diver Dennis Morse had one of the world’s largest lotology collections. It included over 250,000 losing scratch-off tickets.

14. Arctophiles

Arctophiles have the cuddliest collections; they stockpile teddy bears.

15. Galanthophiles

Galanthophiles are avid collectors of the various cultivars of the small white-flower-bearing plant known as the snowdrop.

16. Tyrosemiophiles

Tyrosemiophiles collect cheese labels.

17. Fusilatelists

Fusilatelists collect phone cards issued by telecom companies. The word is apparently largely used in the U.K. On this side of the pond, calling card collectors are known as telegerists.

18. Helixophiles

Helixophiles probably throw the best parties; they study and collect corkscrews.

19. Brandophilists

Brandophilists collect cigar bands.

20. Entredentolignumologists

Entredentolignumologists may or may not exist, but some books and several websites use this mouthful to describe collectors of toothpick boxes.

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!

200 Health Experts Call for Ban on Two Antibacterial Chemicals

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.
