With their words, actions, and unconditional love, mothers have a profound influence on their children. Our mothers give us life, nurture us, and support us as we grow from babies to adults. They teach us, take care of us, and give us advice (wanted or unwanted!), and often provide this sort of motherly presence for many others in their lives as well. To celebrate Mother’s Day, here are 25 of history’s greatest moms.

1. MARIE CURIE

Although scientist Marie Curie (1867—1934) is best known for being the first woman to win a Nobel Prize, she also raised her two young daughters alone after her husband died in an accident in 1906. One of their daughters, Irène Joliot-Curie, went on to co-win the Nobel Prize in Chemistry with her husband for their own work with radioactivity. Joliot-Curie said her mother instilled hard work and flexibility in her children: “That one must do some work seriously and must be independent and not merely amuse oneself in life—this our mother has told us always, but never that science was the only career worth following.”

2. SOJOURNER TRUTH

In 1826, Sojourner Truth (circa 1797—1883) and her baby daughter escaped slavery in Ulster County, New York. Soon after her escape, she heard that her 5-year-old son, Peter, was illegally sold to a man in Alabama. Truth raised money for a lawyer, filed a complaint in court, and successfully got Peter out of slavery—a landmark case in which a black woman successfully sued a white man in court. Truth went on to become a Christian preacher in New York City and toured the northeast, speaking about the Bible, abolition, and women’s suffrage.

3. ABIGAIL ADAMS

As the wife of President John Adams, Abigail Adams (1744 —1818) was the second First Lady of the United States. Because her husband was often away from home for work, she often single-handedly ran their farm, wrote letters supporting equal rights for women and the abolition of slavery, and educated their five kids who survived into childhood—including future president John Quincy Adams. Quincy Adams wrote: "My mother was an angel upon earth. She was a minister of blessing to all human beings within her sphere of action. Her heart was the abode of heavenly purity… She was the real personification of female virtue, of piety, of charity, of ever active and never intermitting benevolence."

4. IRENA SENDLER

Irena Sendler (1910—2008) was a Polish employee at the Warsaw Social Welfare Department who smuggled almost 2500 Jewish children out of the Warsaw Ghetto during the Holocaust, saving their lives. Using the code name Jolanta, she gave these children false identification documents, established temporary (non-Jewish) identities for them, and placed them in convents, orphanages, and Christian homes. Although the Nazis arrested her, tortured her, and sentenced her to execution (she survived because the Gestapo was bribed), she didn’t give them any information about the whereabouts of the children or the inner workings of her smuggling operation. A mother of three kids herself, Sendler received Poland’s Order of the White Eagle award in 2003.

5. KATHY HEADLEE

Kathy Headlee, a mother of seven (the youngest of whom she adopted from Romania), started Mothers Without Borders to help orphaned children around the world. Beginning in 1992, she led a group of volunteers to distribute relief supplies to orphanages and train caregivers in Romania. Since then, Mothers Without Borders has sent volunteers to help children in Bolivia, Bosnia, Guatemala, India, Mexico, Zimbabwe, Uganda, and Nepal.

6. J.K. ROWLING

J.K. Rowling wrote the first four Harry Potter books as a single mother (while briefly receiving state benefits to get by), and she now serves as the president of Gingerbread, an organization that works with single parents and their children find resources and programs to help them succeed. “I am prouder of my years as a single mother than of any other part of my life,” Rowling said of that time and the work she put in. For Mother’s Day 2016 in the UK (which occurs in March), she tweeted: “Today's Mother's Day in the UK. If your mum isn't here to treat, do something nice for yourself, because she's part of you. Take a hug, too.”

7. HOELUN

Famous as the mother of Genghis Khan, she survived getting kidnapped, widowhood, and being an outcast, to becoming the mother and advisor to one of the largest empires the world has ever known (as well as being one of the few people who could yell at Genghis and get away with it). Around the time of her first marriage, she was kidnapped by Yesukhei, the chief of a minor clan (legend has it she took off her shirt, threw it to her husband, and shouted “Fly for your life, and while you live remember my fragrance”), and was forced to marry her captor. Several years (and children) later, Yesukhei was killed and Hoelun and her young children were kicked out of the clan, forced to barely survive on whatever they could forage on the Mongolian steppes. Eventually, one of her children with Yesukhei, Genghis Khan, would become a great conqueror—but his mother could still put him in his place. According to Frank McLynn in Genghis Khan: His Conquests, His Empire, His Legacy, Genghis was planning to execute his brother for treason when Hoelun found out, traveled to Genghis’s headquarters, and begged Genghis to be merciful. When that didn’t work, “Hoelun grew angry, got to her feet and roundly rebuked the khan for thinking to execute his brother … Genghis raised her up and said he would grant the boon because of his love and deference for his mother.”

8. CANDY LIGHTNER

In 1980, a hit-and-run drunk driver killed one of Candy Lightner’s 13-year-old twin daughters, Cari. The driver had had three prior convictions for drunk driving, and had been arrested two days prior for a different hit-and-run. Within a few months, Lightner founded Mothers Against Drunk Driving (MADD) to try to end drunk driving, pass tougher legislation, and help the victims of drunk drivers. Through its work to raise awareness and get legislation passed, MADD has helped save hundreds of thousands of lives.

9. WARIS DIRIE

In 1970 when she was 5 years old, Waris Dirie was a victim of female genital mutilation in her home of Somalia. Then, when was 13, her parents arranged for her to marry a man in his sixties; she ran away from home and eventually arrived in London. Although she became a successful model (and even appeared in a 1987 James Bond film), she retired from modeling in 1997 to devote her time to combating female genital mutilation, partially through her work as a UN Special Ambassador. She founded an organization called Desert Flower that combats female genital mutilation around the world. As the mother of four children, she told Harper’s Bazaar that female genital mutilation isn’t just a women’s issue: “Every education begins with Mama. We have to rethink what we teach our sons. That's the most important thing."

10. INDIRA GANDHI

As India’s first female Prime Minister, Indira Gandhi (1917—1984) worked to institute democracy and create jobs to combat food shortages—she was responsible for India's green revolution, which made the country self-sufficient and no longer reliant on imported grains. “Education is a liberating force, and in our age it is also a democratizing force, cutting across the barriers of caste and class, smoothing out inequalities imposed by birth and other circumstances,” she famously stated. She also entrusted a sense of duty in her two sons, Rajiv and Sanjay Gandhi, who both grew up to become politicians; Rajiv became Prime Minister of India after his mother was assassinated in 1984.

11. ANNE-MARIE SLAUGHTER

After working as a law professor and academic dean, Anne-Marie Slaughter (born 1958) was the first woman to serve as director of Policy Planning for the U.S. State Department. In 2012, she wrote a massively popular article for The Atlantic, called “Why Women Still Can’t Have It All.” She discussed her decision to leave her high-stress government job so she could be closer to home and take better care of her two teenage sons. Her article sparked a national discussion about how mothers balance work and home life, and how society and the workplace need to change to better facilitate mothers who work.

12. ELIZABETH CADY STANTON

Elizabeth Cady Stanton (1815—1902) was a leader in the women’s suffrage and abolitionist movements, all while raising her seven children. She worked with Susan B. Anthony to establish the National Woman Suffrage Association, successfully helping to get women the right to vote via the 19th Amendment. In addition to writing articles and giving speeches on the topic of universal suffrage, Stanton supported education for girls, and her own daughters went to college at Vassar and Columbia.

13. DANA SUSKIND

Dr. Dana Suskind, a widowed mother of three, is a pediatric surgeon at the University of Chicago who founded the Thirty Million Words Initiative to encourage parents to talk frequently to their babies. Based on her research, she focuses on educating parents on the importance that speaking and interacting in the first three years of a child’s life has on that child's brain growth and development.

14. NANCY EDISON

The youngest of Nancy Edison’s seven kids was Thomas Alva Edison. Although some stories about his mother’s virtues were most likely exaggerated, we do know that rather than give up on his education, Nancy Edison decided to homeschool her son after his teacher deemed him "addled" (i.e. mentally ill or incompetent). Edison, who may just have been dyslexic in a time before that learning disorder was studied or understood, said of her: “My mother was the making of me. She was so true, so sure of me; and I felt I had something to live for, someone I must not disappoint.”

15. JULIE ANDREWS

Although you may know Dame Julie Andrews (born 1935) for her film roles as Mary Poppins and Maria Von Trapp (two surrogate-mothers of sorts for generations of children), she’s also an author. Andrews writes The Very Fairy Princess children’s book series with her daughter, Emma Walton Hamilton. Hamilton told Today that her mom was firm, protective, and despite her busy schedule, “very hands-on, always there making eggs at 5 o’ clock in the morning before we went to school.” Practically perfect in every way.

16. LOU XIAOYING

Lou Xioaying was a poor, uneducated woman who supported herself by scavenging through the trash in Jinhua, China, but starting in 1972, she adopted or rescued 30 babies she found in the trash. The chaos of the Cultural Revolution (and later China’s one-child policy), and extreme poverty, especially in rural areas, meant that some parents dumped their unwanted babies in the garbage. “These children need love and care. They are all precious human lives," Xioaying, who had one biological daughter at the time she began rescuing infants, told the press in 2012. "I do not understand how people can leave such a vulnerable baby on the streets.”

17. PRINCESS DIANA

Diana, Princess of Wales (1961—1997) used her status as a royal figure to work with charities that supported children’s hospitals and to raise awareness and combat landmines, which were a significant problem in the '90s. Years after her death in 1997—her sons were 15 and 12 years old when she died—her legacy remains one of humanitarianism. Her oldest, Prince William, notably became a royal patron of a Child Bereavement charity. Speaking about Mother’s Day, he said: “I too have felt and still feel the emptiness on such a day as Mother's Day.”

18. ERMA BOMBECK

Humor writer Erma Bombeck (1927—1996) wrote books and syndicated newspaper columns about life as a suburban housewife in the Midwest. Taking inspiration from her experiences with her adopted daughter and two biological sons, she told stories and made quips about housework that helped a generation of stay-at-home and newly working mothers find humor in the messiness of their lives. And as one might assume from her sharp-witted jokes, she brought her children up to be independent and passionate. “She liked people who were strong and held their own—she was a very big presence,” her daughter Betsy told People. "If you couldn't hold your own, she could roll over you."

19. THERESA KACHINDAMOTO

As a Malawi chieftain, Theresa Kachindamoto presides over nearly 900,000 Malawians. Because poor parents struggle to feed their children, Malawi has a high child marriage rate—one in two girls is married before age 18. Kachindamoto, who has put laws in place to break up approximately 850 child marriages, organizes meetings to speak to Malawians about the dangers of child marriages (including HIV) and the benefits of education for girls and boys. And although she's received backlash for telling families how to raise girls when she herself has five boys, she also works to end cultural sexual initiation rituals, in which a young girl’s parents pay an older man to “teach” her how to have sex, and she's trying to raise the legal age of marriage in the Dedza district of Malawi to 21.

20. ANGELINA JOLIE

Because of her humanitarian work supporting refugees and education, Oscar-winning actress Angelina Jolie has become as well-known for her charity work as she has for her film roles. Jolie first got involved with humanitarian work for refugees and people displaced because of conflict when she was filming Lara Croft: Tomb Raider in Cambodia in 2000. She adopted a son from the country, and eventually adopted children from Ethiopia and Vietnam as well (in addition to her three biological children with husband Brad Pitt). And though she has traveled to more than 30 countries in her role as a UN Goodwill Ambassador, Brad Pitt told The Wall Street Journal that when she has a day off, “the first thing she does is get up and take the kids out. This is the most important ‘to do’ of the day. No matter how tired she might be, she plans outings for each and all.”

21. MARY KAY ASH

Mary Kay Ash (1918—2001) was 45 years old when she founded Mary Kay Cosmetics in 1963, and it has since become a billion-dollar cosmetics company. As a single mom, she was working in sales at a home products company to support her three children, but she was repeatedly passed over for promotions, despite her being one of the top sales directors. Ash took those skills with her when she launched her namesake company, and she worked to give hundreds of thousands of women the opportunity to work as sales consultants on their own time, effectively becoming their own bosses.

22. MARY MAXWELL GATES

The mother of Bill Gates, Mary Maxwell Gates (1929—1994) served on the board of directors for corporations and nonprofit organizations in Seattle. She helped convince leaders at I.B.M. to hire Microsoft to create an operating system, and following that contract, Microsoft went on to achieve massive success. But more importantly, Gates encouraged her son to focus on philanthropy, and the effects of his success are now contributing to worldwide causes because of it. As of 2015, the Bill and Melinda Gates Foundation has given billions of dollars to fight malaria, HIV, polio, and poor sanitation, and to improve opportunities for education.

23. ALBERTA KING

The mother of Martin Luther King, Jr., Alberta Williams King (1904—1974) played the organ and founded the choir at Atlanta’s Ebenezer Baptist Church, and she was also involved with women’s groups, the NAACP, and the YWCA. She set about to raise her three children with a healthy sense of self-respect and taught them that the segregation they saw every day was simply "a social condition rather than a natural order," as MLK Jr. wrote in his autobiography. "She made it clear that she opposed this system and that I must never allow it to make me feel inferior. … At this time Mother had no idea that the little boy in her arms would years later be involved in a struggle against the system she was speaking of." In 1974, six years after her son was assassinated in Memphis, Alberta King was shot and killed at her organ at her church.

24. JULIA WARD HOWE

In 1870, writer Julia Ward Howe (1819—1910, who is best known for writing "The Battle Hymn of the Republic") merged her interests in suffrage and pacifism by writing an “Appeal to Womanhood throughout the World.” Also called the “Mother’s Day Proclamation,” the appeal urged women to come together to support peace. Howe viewed women, who were the ones losing husbands and sons to war, as responsible for stopping war. Although she had six children, Howe made time to write essays and organize rallies for an annual Mother’s Day for Peace, planting the seeds of what would eventually become Mother’s Day.

25. ANN JARVIS

Ann Jarvis (1832—1905) inspired the movement that eventually made Mother’s Day into a national holiday. After most of her babies died of diseases—only four of her possibly 13 children survived to adulthood—she wanted to help other mothers. She organized Mother's Day Work Clubs in what is now West Virginia to help provide medical care, raise money for medicines, and improve sanitary conditions for poor mothers.

After her death, Jarvis’s daughter Anna Jarvis built off of the work of her mother by writing letters and giving speeches in support of Mother’s Day, and President Woodrow Wilson designated Mother’s Day as a national holiday in 1914. Ironically, Jarvis never became a mother herself, and she became horrified by how flower, chocolate, and greeting card companies exploited Mother’s Day for their own financial gain. Jarvis advocated boycotts of Mother’s Day and tried to sue companies that were commercializing the holiday. But the sentiment of appreciating mothers and all the work they do remained, even if the commercial aspect never disappeared.

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

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

Nick Briggs/Comic Relief

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.
