The Night The Beatles Rocked Shea Stadium

Original image

Though the Fab Four found it hard to remember the second occasion, the Beatles actually played Shea Stadium twice. When he was later asked about the "second Shea Stadium concert," George Harrison replied, "Did we play Shea twice?" Ringo Starr was asked the same question and gave the same exact response, "Did we play Shea twice?"


This is rather understandable, with the Beatles' extraordinarily eventful career, the excessive drugs taken, and the natural flaws of memory. Another word would probably also apply: anti-climactic. The first Beatles concert is often considered an apogee, some kind of peak in the unforgettable phenomena we know as "Beatlemania." After their monumental first Shea concert, the second one just over a year later was surely anti-climactic -- the tickets didn't even sell out. (The poster at left is for the less-memorable second concert at Shea Stadium.)


The first Beatles concert at Shea Stadium was on August 15, 1965. Any Beatles fan worth his or her salt knows this one as "The Shea Stadium Concert."

A Full House

Although the Beatles had sold out countless theaters, local auditoriums, and dance halls, no rock group had ever played a concert at an actual sports stadium before. The crowd was at capacity, an eye-popping 55,600 fans, mostly screaming, crying, and even fainting women and teenage girls.

Interestingly, among the screaming, worshiping fans were two future Beatle wives. Both Linda Eastman and Barbara Bach (the future wives of Paul and Ringo, respectively) were sitting amongst the other adoring fans. (One has to wonder what was going through those girls' minds at the time.)

The boys were dramatically escorted to the roof of the World's Fair in a whirling helicopter. According to George, en route to the rooftop, the pilot was zipping and whizzing them wildly over the Big Apple, pointing out the various sights, as the Beatles sat in slight terror at the aerial acrobatics. The boys were then driven to the concert in a Wells-Fargo Bank van.

After they were deposited at the stadium, each of the Beatles was given his own little Wells-Fargo badge. (In the film of the concert, you can spot each Beatle proudly wearing his Wells-Fargo badge pinned to his jacket.)

Once the previous acts finished their obligatory, thankless performances, the Beatles walked out onto the field like four deities. The noise was deafening -- in the video footage, some of the security people can be seen putting their hands over their ears or sticking their fingers in their ears to block out the noise. Thousands of bright camera flashbulbs greeted the Beatles as they entered, making the field look like a wild electronics laboratory.

The boys nervously picked up their guitars and Ringo climbed aboard his drum kit. They stood in the middle of Shea Stadium, small and distant figures, which probably added to the adoration and surrealism of the moment.

It was a typically brief Beatles concert, just 12 songs played in about 30 minutes. The Beatles used their "new" 100-volt amps, rather like using a portable hand mic to get an interview with King Kong, and throughout the deafening roar, they couldn't hear a note any of them played (or sang).

INTERVIEWER: "Does it bother you that you can't hear what you sing during a concert?"

JOHN LENNON: "No, we don't mind. We've got the records at home."

Because of the excessive noise and the need to somehow keep some kind of a beat, Ringo later confessed to watching the swinging rear ends of his three bandmates to give him some semblance of rhythm.

John opened with his version of "Twist and Shout," a usual routine, but Paul, George, and Ringo all noticed something slightly different about John. According to George, John Lennon "cracked up" that night. The surrealism of the event caught Lennon's fancy and, always the craziest of the Fab Four, John just "lost it."

In the video footage, John can be seen cackling and breaking up with mad glee several times, as the other boys look over the crowd, and each other, with slight disbelief. At one point, John holds his arms out-stretched and starts chanting, in a Peter Sellers-like voice, up at some imaginary heavenly presence above him. At another point, as Paul talks to the crowd, John does his usual spastic clawed hands impression and stomps his feet. (But that was a regular part of John's routine in those pre-politically correct times.)

During the closing number, as Paul sang "I'm Down," John went over to play the electric organ. Lennon started playing the organ with his elbow and laughing devilishly. The normally staid and conventional Paul is seen doing a full 360-degree spin, in seemingly pure exhilaration. Even the usually stone-faced George laughed out loud at John's antics.

In between the "Twist and Shout" and "I'm Down" bookends, George and Ringo each performed their obligatory solo turns. John and Paul rotated and sang lead in the other ten songs.

Thus, the band played on.

And then, the most amazing 30-minutes of condensed music ended in a flash, and the Fab Four tromped off the field, exhausted.

The concert pulled in a then-record gross of $304,000, of which the Beatles would receive half. It was noted, at the time, as the biggest grossing event "in the history of show business." (Tickets sold for the ridiculous prices of $4.50, $5.00, and $5.75.)

Many years later, John Lennon ran into Sid Bernstein, the producer of the Shea Stadium concert. As they happily reminisced about the Shea concert, John looked at Sid with a twinkle in his eye and said, "We reached the top of the mountain, Sid."

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning
May 21, 2017

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!

8 Common Dog Behaviors, Decoded
May 25, 2017

Dogs are a lot more complicated than we give them credit for. As a result, sometimes things get lost in translation. We’ve yet to invent a dog-to-English translator, but there are certain behaviors you can learn to read in order to better understand what your dog is trying to tell you. The more tuned-in you are to your dog’s emotions, the better you’ll be able to respond—whether that means giving her some space or welcoming a wet, slobbery kiss. 

1. What you’ll see: Your dog is standing with his legs and body relaxed and tail low. His ears are up, but not pointed forward. His mouth is slightly open, he’s panting lightly, and his tongue is loose. His eyes? Soft or maybe slightly squinty from getting his smile on.

What it means: “Hey there, friend!” Your pup is in a calm, relaxed state. He’s open to mingling, which means you can feel comfortable letting friends say hi.

2. What you’ll see: Your dog is standing with her body leaning forward. Her ears are erect and angled forward—or have at least perked up if they’re floppy—and her mouth is closed. Her tail might be sticking out horizontally or sticking straight up and wagging slightly.

What it means: “Hark! Who goes there?!” Something caught your pup’s attention and now she’s on high alert, trying to discern whether or not the person, animal, or situation is a threat. She’ll likely stay on guard until she feels safe or becomes distracted.

3. What you’ll see: Your dog is standing, leaning slightly forward. His body and legs are tense, and his hackles—those hairs along his back and neck—are raised. His tail is stiff and twitching, not swooping playfully. His mouth is open, teeth are exposed, and he may be snarling, snapping, or barking excessively.

What it means: “Don’t mess with me!” This dog is asserting his social dominance and letting others know that he might attack if they don’t defer accordingly. A dog in this stance could be either offensively aggressive or defensively aggressive. If you encounter a dog in this state, play it safe and back away slowly without making eye contact.

4. What you’ll see: As another dog approaches, your dog lies down on his back with his tail tucked in between his legs. His paws are tucked in too, his ears are flat, and he isn’t making direct eye contact with the other dog standing over him.

What it means: “I come in peace!” Your pooch is displaying signs of submission to a more dominant dog, conveying total surrender to avoid physical confrontation. Other, less obvious, signs of submission include ears that are flattened back against the head, an avoidance of eye contact, a tongue flick, and bared teeth. Yup—a dog might bare his teeth while still being submissive, but they’ll likely be clenched together, the lips opened horizontally rather than curled up to show the front canines. A submissive dog will also slink backward or inward rather than forward, which would indicate more aggressive behavior.

5. What you’ll see: Your dog is crouching with her back hunched, tail tucked, and the corner of her mouth pulled back with lips slightly curled. Her shoulders, or hackles, are raised and her ears are flattened. She’s avoiding eye contact.

What it means: “I’m scared, but will fight you if I have to.” This dog’s fight or flight instincts have been activated. It’s best to keep your distance from a dog in this emotional state because she could attack if she feels cornered.

6. What you’ll see: You’re staring at your dog, holding eye contact. Your dog looks away from you, tentatively looks back, then looks away again. After some time, he licks his chops and yawns.

What it means: “I don’t know what’s going on and it’s weirding me out.” Your dog doesn’t know what to make of the situation, but rather than nipping or barking, he’ll stick to behaviors he knows are OK, like yawning, licking his chops, or shaking as if he’s wet. You’ll want to intervene by removing whatever it is causing him discomfort—such as an overly grabby child—and giving him some space to relax.

7. What you’ll see: Your dog has her front paws bent and lowered onto the ground with her rear in the air. Her body is relaxed, loose, and wiggly, and her tail is up and wagging from side to side. She might also let out a high-pitched or impatient bark.

What it means: “What’s the hold up? Let’s play!” This classic stance, known to dog trainers and behaviorists as “the play bow,” is a sign she’s ready to let the good times roll. Get ready for a round of fetch or tug of war, or for a good long outing at the dog park.

8. What you’ll see: You’ve just gotten home from work and your dog rushes over. He can’t stop wiggling his backside, and he may even lower himself into a giant stretch, like he’s doing yoga.

What it means: “OhmygoshImsohappytoseeyou I love you so much you’re my best friend foreverandeverandever!!!!” This one’s easy: Your pup is overjoyed his BFF is back. That big stretch is something dogs don’t pull out for just anyone; they save that for the people they truly love. Show him you feel the same way with a good belly rub and a handful of his favorite treats.

The best way to say “I love you” in dog? A monthly subscription to BarkBox. Your favorite pup will get a package filled with treats, toys, and other good stuff (and in return, you’ll probably get lots of sloppy kisses). Visit BarkBox to learn more.
