11 Unserious Photos of Einstein for His Birthday

Original image

Albert Einstein was born on this date in 1879. The German-born Nobel Prize winner possessed a quick, sharp wit along with his enviable IQ, and his tendency to offset the very serious matter of general relativity with a little lighthearted humor is evident in this series of photos.

1. Getting Tongues Wagging

In honor of Einstein’s 72nd birthday, friends and colleagues met at the Princeton Club for a celebration heavy on both merriment and press photographers. Eager cameraman Arthur Sasse tried to coax one final smile from the physicist as he departed for the night; worn down by the festivities, Einstein stuck out his tongue instead. The photo has since become a cultural icon, which Einstein himself liked so much that he ordered nine prints made, and used it to adorn greeting cards.

2. The Lady and the Scientist

Behind this great man was this great woman: Elsa Einstein, Albert’s second wife, who moved with him from Berlin to Princeton, and brought along her two daughters from a previous marriage to form the cohesive Einstein family unit.

3. An Enviable Mustache

Despite the uniformity of dress and prevalence of facial hair in this old photograph, something still stands out about Einstein’s trademark mustache—the same mustache that adorns the face of this bobblehead available in the Mental Floss store.

4. Nice Sandals

Southold Historical Society

Pictured here in September 1939, Einstein relaxes on the beach near his Long Island summer home with friend and local department store owner David Rothman. After some initial confusion in the store resulting from Einstein’s thickly accented request for a pair of “sundahls,” which Rothman interpreted as “sundial,” the scientist was able to successfully purchase the white sandals on his feet for $1.35. He laughed off the episode, blaming “mine atrocious accent!” The men remained close friends thereafter, later forming a neighborhood string quartet together.

5. Easy Rider

California Institute of Technology Archives

Even riding free and easy through Santa Barbara, California in this 1933 photo, the award-winning physicist maintains a classic look in his cardigan and dress pants.

6. Stick that in your pipe

An avid smoker, Einstein was rarely seen without his pipe. Despite our contemporary health concerns about the ill effects of tobacco, he was convinced that “pipe smoking contributes to a somewhat calm and objective judgment in all human affairs.”

7. Style for Miles

His face may be perfectly serious, but his robe is perfectly silly.

8. Rock 'em, Sock 'Em

For all his brilliance, Albert Einstein in his later years began to look less like the foremost physicist of his age, and more like the friendly neighborhood grandpa who wore socks with sandals—except that according to many accounts, the scientist with his relentlessly practical mind could never reconcile himself to wear socks regularly, knowing that his big toe would inevitably wear a hole in them and believing that shoes alone would suffice to cover his feet. In light of that information, these socks with Einstein’s face printed on them are hugely ironic.

9. Fierce Footwear

These slippers presumably required no socks.

10. A Hairy Situation

Frankfurt.de

In Albert Einstein’s windswept white mane lie the origins of the mad scientist hairstyle.

11. Puppetmaster

Harry Burnett, 1931

After witnessing a performance by the Yale Puppeteers at the Teatro Torito in Los Angeles, Einstein had only one complaint about his miniature alter ego: “The puppet wasn’t fat enough!” he claimed, and took a letter out of his pocket, crumpled it up, and padded out the character’s belly for accuracy’s sake.  He might have been more satisfied with this plush, soft-toy representation of himself, available in the Mental Floss store—additional stomach padding not included.

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!

What Happened to Jamie and Aurelia From Love Actually?
May 26, 2017

Fans of the romantic-comedy Love Actually recently got a bonus reunion in the form of Red Nose Day Actually, a short charity special that gave audiences a peek at where their favorite characters ended up almost 15 years later.

One of the most improbable pairings from the original film was between Jamie (Colin Firth) and Aurelia (Lúcia Moniz), who fell in love despite almost no shared vocabulary. Jamie is English, and Aurelia is Portuguese, and they know just enough of each other’s native tongues for Jamie to propose and Aurelia to accept.

A decade and a half on, they have both improved their knowledge of each other’s languages—if not perfectly, in Jamie’s case. But apparently, their love is much stronger than his grasp on Portuguese grammar, because they’ve got three bilingual kids and another on the way. (And still enjoy having important romantic moments in the car.)

In 2015, Love Actually script editor Emma Freud revealed via Twitter what happened between Karen and Harry (Emma Thompson and Alan Rickman, who passed away last year). Most of the other couples get happy endings in the short—even if Hugh Grant's character hasn't gotten any better at dancing.
