11 Very Important Things to Know About Cider

Original image

By Erika Janik


Forget the juice; we're talking about the hard stuff. Here are 11 facts everyone should know about good old-fashioned apple cider.


1. Back in the 14th century, it is believed that kids were baptized in cider since it was often more sanitary than water.


2. An apple beverage a day? President John Adams drank a tankard of cider every morning because he believed it promoted good health. And it must have—Adams lived to 90, making him our third longest living president, behind Ford & Reagan.


3. Cider was so important to early Americans that one in every ten farms in New England operated its own cider mill by the time of the American Revolution.

4. But why didn't the drink stay popular over the years? The Temperance movement killed the business. Fired up by speeches from ministers and politicians, many farmers destroyed their "demon orchards," sparing only the trees used for sweet juice. During the years when Prohibition was enacted, American cider production in the fell by 76%.

5. The best cider apples seem to have the best names: Hangdown, Chibble's Wilding, Kentish Fill-Basket, and Glory of the West.

6. If you want to make great cider, be sure to practice your wassailing. The English custom, used to appease the deities of the apple trees, was believed necessary to ensure healthy crops. Here's how to honor the spirits: Place a jug of cider or piece of cider-soaked toast on the biggest apple tree. Then sing a chant or song. Finish by banging on kettles and blowing horns to scare away any evil spirits lingering in your orchard. It's that easy.

7. Also, you'll need lots of apples. It takes about 36 pieces of fruit to make one gallon of the good stuff.

8. When Caesar and his invading soldiers stormed through England in 55 BCE, they found Celts sipping a brew made from crab apples. The troops were quick to pick up the habit and take it back to Rome.

9. Other fruits can be used to make cider-like drinks, too. Perry comes from fermented pear juice, cyser is cider fermented with honey, and plum jerkum—made from plums—supposedly has some strange intoxicating effects. According to legend, it leaves "the head clear, while paralyzing the legs."

10. Looking for the proper way to care for a dead genius' brain? For more than 40 years, Einstein's cranium was stored in a box labeled Costa Cider. Actually, it was stored in two mason jars in the Cider box, under pathologist Thomas Harvey's sink.

11. Of course, if this moderately alcoholic beverage doesn't do it for you, it's possible to make hard ciders even harder. Apple brandy and applejack are distilled ciders, and applejack, in particular, is really potent. It's nicknamed the "essence of lockjaw."

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!

Why Your iPhone Doesn't Always Show You the 'Decline Call' Button

When you get an incoming call to your iPhone, the options that light up your screen aren't always the same. Sometimes you have the option to decline a call, and sometimes you only see a slider that allows you to answer, without an option to send the caller straight to voicemail. Why the difference?

A while back, Business Insider tracked down the answer to this conundrum of modern communication, and the answer turns out to be fairly simple.

If you get a call while your phone is locked, you’ll see the "slide to answer" button. In order to decline the call, you have to double-tap the power button on the top of the phone.

If your phone is unlocked, however, the screen that appears during an incoming call is different. You’ll see the two buttons, "accept" or "decline."

Either way, you get the options to set a reminder to call that person back or to immediately send them a text message. ("Dad, stop calling me at work, it’s 9 a.m.!")
