10 Other Mother’s Days from Around the World

After her mother passed away in 1905, Anna Jarvis resolved to dedicate a day to her mother, and mothers everywhere. Little did she know, and evidently much to her chagrin, Mother’s Day fast became a commercial phenomenon. Its popularity spread worldwide and many countries, particularly in the Western world, adopted the second Sunday in May as their official Mother’s Day. But not every nation followed suit—perhaps to the chagrin of their local flower companies. In fact, Mother’s Day in many countries has little or nothing to do with Anna Jarvis’ creation, nor does it always occur in May. These are just a few of those other Mother’s Days.

1. UK: Mothering Sunday, Fourth Sunday of Lent

The name may sound strikingly similar to its American counterpart, but the origins of Mothering Sunday are quite different. By most historical accounts, it was the Church of England that created Mothering Sunday to honor the mothers of England, and later to commemorate the “Mother Church” in all its spiritual nurturing glory. Hundreds of years ago, good Christians were expected to make at least one return to their mother church each year. In other words, Mothering Sunday was the ultimate guilt trip to visit the woman or entity that gave them life. Was that so much to ask? The fourth Sunday of Lent became the designated day to make this journey, and remains the go-to holiday to celebrate Moms to this day. 

2. Thailand: Mother’s Day, August 12

Her Majesty Sirikit the Queen of Thailand is also considered the mother of all her Thai subjects. In light of her royal maternal status, the Thai government made her birthday, August 12, Thailand’s official Mother’s Day in the 1970s. It remains a national holiday, celebrated countrywide with fireworks and candle-lighting. In related holidays, Father’s Day in Thailand falls on the current King’s birthday, December 5.

3. Bolivia: Mother’s Day, May 27

During its struggle for independence from Spain in the early 19th century, Bolivia saw many of its fathers, sons, and husbands injured and killed on the battlefields. One group of women from Cochabamba refused to stand idly by; on May 27, they banded together to fight the Spanish Army on Coronilla Hill. Though hundreds died in battle, the legacy of their contributions lives on thanks to a national law passed in the 1920s making the day on which the “Heroines of Coronilla” took to the streets national Mother’s Day.

4. Indonesia: Mother’s Day/Women’s Day, December 22

Made official in 1953 by its president, Indonesia's Mother’s Day falls on the anniversary of the First Indonesian Women’s Congress (1928). The first convening of women in a governmental body is still considered pivotal in launching organized women’s movements throughout Indonesia. The holiday was created to celebrate the contributions of women to Indonesian society.

5. Middle East (Various): Mother’s Day/Vernal Equinox, March 21

Egyptian journalist Mustafa Amin introduced the idea of a Mother’s Day to his home country, and it quickly spread throughout much of the region. Inspired by a story of a thankless widow ignored by an ungrateful son, Amin and his brother Ali successfully proposed a day in Egypt to honor all mothers. They decided the first day of spring, March 21, was most appropriate to celebrate the ultimate givers of life. It was first celebrated in Egypt in 1956, and is still observed throughout the region from Bahrain to the United Arab Emirates to Iraq.

6. Nepal: Mother Pilgrimage Fortnight/Mata Tirtha Aunsi, Last Day of the Baishakh month (usually April or May)

Stemming from an ancient Hindu tradition, this festival of honoring mothers is still commonly celebrated in Nepal. The holiday honors both the living and the dead equally. Traditionally, those honoring mothers who have passed away make a pilgrimage to the Mata Tirtha ponds near Kathmandu. A large carnival is also held in the Mata Tirtha village. Children show their mothers appreciation with sweets and gifts.

7. Israel: Family Day/The Holiday Formally Known as Mother’s Day, 30th Day of Shevat (usually February)

Henrietta Szold never had any children of her own, but that didn’t stop her from touching the lives of many young ones. Szold played an active role in the Youth Aliya organization, through which she helped protect many Jewish children from the horrors of the Holocaust. This earned her a reputation as the “mother” of all children. In the 1950s, an 11-year-old girl named Nechama Biedermann wrote to the children’s publication Haaretz Shelanu proposing they make the date of Szold’s death Israel’s national Mother’s Day. The newspaper readily agreed, as did the rest of the country. Despite the shift to a more gender-balanced Family Day, the holiday’s popularity has waned over the years.

8. Ethiopia: Mother’s Day/Antrosht, When the Rainy Season Ends (October/November)

Rather than tying themselves down to a specific date, Ethiopians wait out the wet season then trek home for a large, three-day family celebration. This feast is known as “Antrosht.” Unlike some western Mother’s Days, the mother plays a key role in preparing the traditional meals for the festival.

9. France: Mother’s Day/Fête des Mères, Last Sunday in May

Celebrating a few Sundays later than the rest of the world feels so, well, French. However, according to one blogger, they may have beat all of us to the punch—sort of. France has a storied history of attempts to create a national Mother’s Day. Napoleon tried to mandate a national maternal holiday at the turn of the 19th century. But things ended up not working out so well for him and his holiday. More than a century later, Lyon held its own Mother’s Day celebration to honor women who lost sons to the First World War. It was not until May 24, 1950 that the Fête des Mères became an officially decreed holiday. 

(The holiday is mandated to occur on the last Sunday in May. However, if that Sunday is also the Pentecost, then Mother’s Day is pushed to the first Sunday in June.)

10. Nicaragua: Mother’s Day, May 30

In the 1940s, President General Anastasio Somoza Garcia declared Mother’s Day in honor of the birthday of his mother-in-law. Despite its brown-nosing origins, it remains a big deal in Nicaragua.

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!

10 Facts About the Tomb of the Unknown Soldier
May 29, 2017
Original image
Library of Congress

On Veterans Day, 1921, President Warren G. Harding presided over an interment ceremony at Arlington National Cemetery for an unknown soldier who died during World War I. Since then, three more soldiers have been added to the Tomb of the Unknowns (also known as the Tomb of the Unknown Soldier) memorial—and one has been disinterred. Below, a few things you might not know about the historic site and the rituals that surround it.

1. THERE WERE FOUR UNKNOWN SOLDIER CANDIDATES FOR THE WWI CRYPT.

To ensure a truly random selection, four unknown soldiers were exhumed from four different WWI American cemeteries in France. U.S. Army Sgt. Edward F. Younger, who was wounded in combat and received the Distinguished Service Medal, was chosen to select a soldier for burial at the Tomb of the Unknowns in Arlington. After the four identical caskets were lined up for his inspection, Younger chose the third casket from the left by placing a spray of white roses on it. The chosen soldier was transported to the U.S. on the USS Olympia, while the other three were reburied at Meuse Argonne American Cemetery in France.

2. SIMILARLY, TWO UNKNOWN SOLDIERS WERE SELECTED AS POTENTIAL REPRESENTATIVES OF WWII.

One had served in the European Theater and the other served in the Pacific Theater. The Navy’s only active-duty Medal of Honor recipient, Hospitalman 1st Class William R. Charette, chose one of the identical caskets to go on to Arlington. The other was given a burial at sea.

3. THERE WERE FOUR POTENTIAL KOREAN WAR REPRESENTATIVES.

The soldiers were disinterred from the National Cemetery of the Pacific in Hawaii. This time, Army Master Sgt. Ned Lyle was the one to choose the casket. Along with the unknown soldier from WWII, the unknown Korean War soldier lay in the Capitol Rotunda from May 28 to May 30, 1958.

4. THE VIETNAM WAR UNKNOWN WAS SELECTED ON MAY 17, 1984.

Medal of Honor recipient U.S. Marine Corps Sgt. Maj. Allan Jay Kellogg, Jr., selected the Vietnam War representative during a ceremony at Pearl Harbor.

5. BUT THE VIETNAM VETERAN WASN'T UNKNOWN FOR LONG.

Wikipedia // Public Domain

Thanks to advances in mitochondrial DNA testing, scientists were eventually able to identify the remains of the Vietnam War soldier. On May 14, 1998, the remains were exhumed and tested, revealing the “unknown” soldier to be Air Force 1st Lt. Michael Joseph Blassie (pictured). Blassie was shot down near An Loc, Vietnam, in 1972. After his identification, Blassie’s family had him moved to Jefferson Barracks National Cemetery in St. Louis. Instead of adding another unknown soldier to the Vietnam War crypt, the crypt cover has been replaced with one bearing the inscription, “Honoring and Keeping Faith with America’s Missing Servicemen, 1958-1975.”

6. THE MARBLE SCULPTORS ARE RESPONSIBLE FOR MANY OTHER U.S. MONUMENTS. 

The Tomb was designed by architect Lorimer Rich and sculptor Thomas Hudson Jones, but the actual carving was done by the Piccirilli Brothers. Even if you don’t know them, you know their work: The brothers carved the 19-foot statue of Abraham Lincoln for the Lincoln Memorial, the lions outside of the New York Public Library, the Maine Monument in Central Park, the DuPont Circle Fountain in D.C., and much more.

7. THE TOMB HAS BEEN GUARDED 24/7 SINCE 1937. 

Tomb Guards come from the 3rd U.S. Infantry Regiment "The Old Guard". Serving the U.S. since 1784, the Old Guard is the oldest active infantry unit in the military. They keep watch over the memorial every minute of every day, including when the cemetery is closed and in inclement weather.

8. BECOMING A TOMB GUARD IS INCREDIBLY DIFFICULT.

Members of the Old Guard must apply for the position. If chosen, the applicant goes through an intense training period, in which they must pass tests on weapons, ceremonial steps, cadence, military bearing, uniform preparation, and orders. Although military members are known for their neat uniforms, it’s said that the Tomb Guards have the highest standards of them all. A knowledge test quizzes applicants on their memorization—including punctuation—of 35 pages on the history of the Tomb. Once they’re selected, Guards “walk the mat” in front of the Tomb for anywhere from 30 minutes to two hours, depending on the time of year and time of day. They work in 24-hour shifts, however, and when they aren’t walking the mat, they’re in the living quarters beneath it. This gives the sentinels time to complete training and prepare their uniforms, which can take up to eight hours.

9. THE HONOR IS ALSO INCREDIBLY RARE.

The Tomb Guard badge is the least awarded badge in the Army, and the second least awarded badge in the overall military. (The first is the astronaut badge.) Tomb Guards are held to the highest standards of behavior, and can have their badge taken away for any action on or off duty that could bring disrespect to the Tomb. And that’s for the entire lifetime of the Tomb Guard, even well after his or her guarding duty is over. For the record, it seems that Tomb Guards are rarely female—only three women have held the post.

10. THE STEPS THE GUARDS PERFORM HAVE SPECIFIC MEANING.

Everything the guards do is a series of 21, which alludes to the 21-gun salute. According to TombGuard.org:

The Sentinel does not execute an about face, rather they stop on the 21st step, then turn and face the Tomb for 21 seconds. They then turn to face back down the mat, change the weapon to the outside shoulder, mentally count off 21 seconds, then step off for another 21 step walk down the mat. They face the Tomb at each end of the 21 step walk for 21 seconds. The Sentinel then repeats this over and over until the Guard Change ceremony begins.
