12 of Old Hickory's Best Lines

Andrew Jackson was many things: Stubborn. Brilliant. Ruthless. Romantic. And insanely quotable. From his hatred of the bank to his hatred of proper spelling, Jackson had a lot to say about a lot of topics. Here are some of his greatest hits.

1. and 2. On banking

“The bank, Mr. Van Buren, is trying to kill me. But I will kill it.” Three days later, Jackson announced his veto of the bank charter.

“I have been afraid of banks.” Jackson is often quoted as saying "I have always been afraid of banks," but the actual quote was, "Ever since I read the history of the South Sea Bubble, I have been afraid of banks."

3. On killing Charles Dickinson in a duel

Though Dickinson shot first and hit Jackson squarely in the chest, nearly killing him, Old Hickory calmly took his shot as if he had not been wounded at all. When a friend expressed his astonishment at Jackson's composure, Jackson stated“If he had shot me through the brain, sir, I should still have killed him.” 

4. On running for president

"Do they think that I am such a damned fool to think myself fit for President of the United States? No, sir; I know what I am fit for. I can command a body of men in a rough way, but I am not fit to be President." 

5. On his demeanor

"I was born for a storm, and a calm does not suit me." 

6. On living

“I try to live my life as if death might come for me at any moment.” Though that may have been true, he was also prepared to fight death tooth and nail. When an assassin tried to kill him in 1835, Jackson beat him in the face with his cane.

7. On spelling

“It’s a damn poor mind that can think of only one way to spell a word.”

8. On regrets

The day after Van Buren was elected president, Jackson took the time to reflect on his own presidency with a friend. When asked if he had any regrets about the last eight years, this was his response: “[That] I didn’t shoot Henry Clay and I didn’t hang John C. Calhoun.” 

9. Further thoughts on John C. Calhoun

"John Calhoun, if you secede from my nation, I will secede your head from the rest of your body." As The Week says, this one is unverified, but given Jackson's character and relationship with Calhoun, it's likely.

10. On the privileged

“It is to be regretted that the rich and powerful too often bend the acts of government to their own selfish purposes.”

11. On taxes

"The wisdom of man never yet contrived a system of taxation that would operate with perfect equality."

12. On Kentuckians

Kentucky sent 2300 militiamen to back Jackson up during the Battle of New Orleans in 1815. Astonished that so many of them showed up without weapons, he uttered the now-famous quote that is proudly emblazoned as Kentucky pride on t-shirts“I never in my life seen a Kentuckian who didn’t have a gun, a pack of cards, and a jug of whiskey.”

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

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.
