What Do the Olympic Rings Mean?

In 1894, Pierre de Frédy, Baron de Coubertin—a French aristocrat and intellectual who had previously attempted to incorporate more physical education in schools—convened a congress in Paris with the goal of reviving the ancient Olympic Games (an idea Coubertin first introduced at a USFSA meeting in 1889). The congress agreed on proposals for a modern Olympics, and the International Olympic Committee was soon formalized and given the task of planning the 1896 Athens Games.

After the 1912 Stockholm Games—the first Games featuring athletes from all five inhabited parts of the world—a design of five interlocked rings, drawn and colored by hand, appeared at the top of a letter Coubertin sent to a colleague. Coubertin used his ring design as the emblem of the IOC's 20th anniversary celebration in 1914. A year later, it became the official Olympic symbol.

The rings were to be used on flags and signage at the 1916 Games, but those games were canceled because of the ongoing World War. The rings made a belated debut at the 1920 Games in Antwerp, Belgium.

Coubertin explained his design in 1931:

"A white background, with five interlaced rings in the centre: blue, yellow, black, green and red ... is symbolic; it represents the five inhabited continents of the world, united by Olympism, while the six colors are those that appear on all the national flags of the world at the present time."

Coubertin used a loose interpretation of "continent" that included Africa, the Americas, Asia, Europe and Oceania. He never said nor wrote that any specific ring represents a specific continent.

Because the rings were originally designed as a logo for the IOC's 20th anniversary and only later became a symbol of the Olympics, it's also probable, according to historian David Young, that Coubertin originally thought of the rings as symbols of the five Games already successfully staged.

ANCIENT RINGS? 

Popular myth (and an academic article) has it that the rings were inspired by a similar, ancient design found on a stone at Delphi, Greece. This "ancient" design, however, is really just a modern prop.

For the 1936 Summer Games in Berlin, Carl Diem, president of the organizing committee, wanted to relay the Olympic Flame from its lighting point in Olympia to the Olympic stadium in Berlin. Diem, it seems, had a flair for theatrics, and included in the relay a stop at Delphi's ancient stadium for a faux-ancient Greek torchbearers' ceremony complete with a faux-ancient, 3-foot-tall stone altar with the modern ring design chiseled into its sides.

After the ceremony, the torch runners went on their way, but no one ever removed the stone from the stadium. Two decades later, British researchers visiting Delphi noticed the ring design on the stone. They concluded that the stone was an ancient altar, and thought the ring design had been used in ancient Greece and now formed "a link between ancient and modern Olympics."

The real story behind the altar was later revealed, and "Carl Diem's Stone" was moved from the stadium and placed near the ticketed entrance to the historic site.

The inspiration for Coubertin's design seems to be a little more modern. Four years before he convened his Olympic congress, he had become president of the French sports-governing body, the Union des Sociétés Françaises de Sports Athlétiques (USFSA). The Union was formed from the merging of two smaller sporting bodies, and to symbolize this, a logo of two interlocking rings—one red and one blue, on a white background—was created and displayed on the uniforms of USFSA athletes.

"It seems quite obvious," says historian Robert Barney in a 1992 Olympic Revue article, "that Coubertin's affiliation with the USFSA led him to think in terms of interlocked rings or circles when he applied his mind towards conceiving a logo ... indeed, a ring-logo that would symbolize his Olympic Movement's success up to that point in time.... Circles, after all, connote wholeness, the interlocking of them, continuity."

LORD OF THE RINGS

The IOC takes their rings very seriously, and the symbol is subject to very strict usage rules and graphic standards, including:

The area covered by the Olympic symbol (the rings) contained in an Olympic emblem (e.g. the 2008 Games emblem) can't exceed one-third of the total area of the emblem.
*
The Olympic symbol contained in an Olympic emblem has to appear in its entirety (no skimping on rings!) and can't be altered in any way.
*
The rings can be reproduced in a solid version (for single color reproduction in blue, yellow, black, green, red, white, gray, gold, silver, or bronze) or an interlocking version (interlaced from left to right; and reproduced in any of the aforementioned colors or full color, in which case the blue, black and red rings are on top and the yellow and green are on the bottom).
*
For reproduction on dark backgrounds, the rings must be a monochromatic yellow, white, gray, gold, silver, or bronze; full color on a dark background is not allowed.

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?

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.
