The Female Jiu-Jitsu Crew That Defended Women's Rights

Had the police known there was barbed wire hidden in the floral arrangements, things might have gone a little differently.

The officers had poured themselves into an assembly hall in Glasgow, Scotland, in March 1914 to arrest Emmeline Pankhurst, one of the loudest voices in the British feminist movement who had traveled from London to rally support for her cause. Women, she declared, deserved the right to vote, to ask for a divorce, or to inherit land.

Anticipating a fight, she arrived with an army of women—roughly 25 in all—collectively known as the Bodyguard. These “Amazons,” as the press breathlessly reported, were trained in the art of jiu-jitsu, club-fighting, and sabotage by Edith Garrud, one of the first female martial arts instructors in Europe. Unlike many who study self-defense, the women weren’t preparing for hypothetical threats. The police had pummeled them with their fists and sticks before, and wouldn’t hesitate to do so again.

Pankhurst had already made police look foolish by evading arrest at the entrance: She simply bought a ticket and walked in, presumed to be a spectator. As she stood holding court, the uniformed officers began to advance, outnumbering the Bodyguard by two to one. One of the women—dubbed “suffragettes” in newspapers— pulled out a pistol and took aim, firing. They were blanks, but it stunned her target. Other officers were tossed in the manner Garrud instructed, tumbling into razor-sharp bouquets. Indian clubs, which were shaped like bowling pins, emerged from the women's dresses and were used to batter their foes. The melee would later be referred to as the “Battle of Glasgow,” with Pankhurst finally being dragged away.

It was little wonder why she needed protection, or why Garrud was the woman for the job—despite the fact that she stood only 4 feet 11 inches tall.

Born in Bath, Somserset, in 1872, Garrud’s parents were unmarried, a shameful circumstance for the time. Sent to live with her aunt, she had difficulty fitting in at school and took to athletics as a means of busying herself. In 1893, she and fellow fitness enthusiast William Garrud were married; in 1899, the couple saw a demonstration by Edward Barton-Wright, a compact man who had developed his own blend of grappling and striking he dubbed Bartitsu—a style (misspelled as “Baritsu”) so well publicized it was name-dropped by Sherlock Holmes in a 1903 Arthur Conan Doyle story.

The Garruds went on to train with Sadakazu Uyenishi, a Japanese jiu-jitsu instructor affiliated with Barton-Wright. When Uyenishi left in 1908, they took over his dojo in Golden Square. Edith ran the women’s and children’s classes, demonstrating how even a small individual could overpower a larger foe using the leverage of jiu-jitsu (at the time often spelled as “ju-jitsu,” jujutsu,” or “jiujitsu.”)

Garrud had gotten some publicity for a short 1907 film reel that displayed her skills and was invited by Pankhurst to appear at a Women’s Social and Political Union meeting in 1909 after William got ill and couldn’t make it. The suffragettes were so impressed by her abilities that they asked her to begin regular training sessions. By December, Garrud was running the Suffragette Self-Defense Club. The idea of a physically domineering woman arming the feminists with combat techniques (even as they wore wide-brimmed hats and elaborate dresses) was something the press couldn’t get enough of.

Garrud’s responsibility was considerable: Pankhurst and her protestors were radicals, setting mailboxes on fire, throwing “flour bombs” at the Prime Minister, and smashing windows of shopkeepers that refused to support their cause. A visiting Mahatma Gandhi addressed the suffragettes in 1909, telling them their cause was just but their tactics unacceptable.  

While Gandhi simply shook his head, police response was brutal: a 1910 confrontation ended with several women battered. When women were arrested and refused to eat in protest, they were force-fed with rubber hoses. Those imprisoned sometimes saw Garrud climbing atop prison walls, singing and waving a flag; those freed were taught how to throw policemen through the air and avoid being bludgeoned by wrapping cotton and cardboard around their ribs.

The suffragettes didn't want to risk arrest for their secret weapon, and so Garrud rarely joined the fray—but she wasn't averse to being an accomplice. Once, after a group of women smashed over 400 shop windows, she instructed them to run back to her dojo, where they changed into grappling uniforms. She stashed their street clothes and weapons in a trap door under the mats. As Garrud told author Antonia Raeburn:

“They were all in their jiu-jitsu coats working on the mats, when bang, bang, bang on the door. Six policemen! I looked very thunderstruck and wanted to know what was the matter. ‘Well, can’t we come in?’ said one of the policemen. I said, ‘No, I’m sorry, but I’ve got six ladies here having a jiu-jitsu lesson. I don’t expect gentlemen to come in here.’…He didn’t see anything, only the girls busy working, and out he went again.”

As the fight dragged on and it became clear Pankhurst was not going to fold, authorities invoked a new law dubbed the Cat and Mouse Act. It stated that protestors who were arrested and refused to eat would be set free. Once they had returned to health, police would re-arrest them. Tempers flared on both sides; the Women’s Social and Political Union even took credit for blowing up a vacant house recently purchased by Chancellor Lloyd-George.

“We mean to have a revolt,” daughter Sylvia Pankhurst said at one rally [PDF]. “I and my friends are out to have a few riots.”

The Pankhursts decided the fugitives needed protection. Garrud was charged with training the Bodyguard, the squad of women who would serve as a barrier to deter cops. They were organized, swift with clubs, and seemingly fearless in the face of badges. Police, aware of Garrud’s tenacious skills, tried spying on their lessons from skylights.

In February 1914, just a month before their rumble in Glasgow, the Bodyguard were faced with another bloody scenario. Emmeline was delivering a rousing speech from a balcony in a Camden Square home. Police were waiting below, eager to re-arrest the fugitive. When she declared she was coming down and dared authorities to stop her, they swarmed her protectors. After a protracted struggle, they finally managed to nab Pankhurst.

Stopping to catch their breath, police looked more closely. They had caught Pankhurst’s double. The real thing had remained inside, spirited away in the opposite direction.

The Bodyguard used wits and jiu-jitsu in equal measure, even knocking one policeman unconscious in front of Buckingham Palace. The only thing that could stop the Pankhursts in their tracks was the declaration of actual war. When World War I broke out, Emmeline decided that women’s rights wouldn’t be of much use if Germans occupied Great Britain and she decided to focus her efforts on keeping her country free.  By war’s end, women finally won their right to vote.

Having sold the dojo in 1925, Garrud was long out of the business of proving doubters wrong, as the times she had done so had left a lasting impression. After tossing one Daily Mirror reporter, he picked himself up and wrote:

“I rose convinced of the efficiency of Jujutsu, and, aching in every limb, crawled painfully away, pitying the constable whose ill-fortune it should be to lay hands on Mrs. Garrud.”

Fit and disciplined, Garrud passed away just shy of her 100th birthday in 1971.

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!

Working Nights Could Keep Your Body from Healing
Original image

The world we know today relies on millions of people getting up at sundown to go put in a shift on the highway, at the factory, or in the hospital. But the human body was not designed for nocturnal living. Scientists writing in the journal Occupational & Environmental Medicine say working nights could even prevent our bodies from healing damaged DNA.

It’s not as though anybody’s arguing that working in the dark and sleeping during the day is good for us. Previous studies have linked night work and rotating shifts to increased risks for heart disease, diabetes, weight gain, and car accidents. In 2007, the World Health Organization declared night work “probably or possibly carcinogenic.”

So while we know that flipping our natural sleep/wake schedule on its head can be harmful, we don’t completely know why. Some scientists, including the authors of the current paper, think hormones have something to do with it. They’ve been exploring the physiological effects of shift work on the body for years.

For one previous study, they measured workers’ levels of 8-OH-dG, which is a chemical byproduct of the DNA repair process. (All day long, we bruise and ding our DNA. At night, it should fix itself.) They found that people who slept at night had higher levels of 8-OH-dG in their urine than day sleepers, which suggests that their bodies were healing more damage.

The researchers wondered if the differing 8-OH-dG levels could be somehow related to the hormone melatonin, which helps regulate our body clocks. They went back to the archived urine from the first study and identified 50 workers whose melatonin levels differed drastically between night-sleeping and day-sleeping days. They then tested those workers’ samples for 8-OH-dG.

The difference between the two sleeping periods was dramatic. During sleep on the day before working a night shift, workers produced only 20 percent as much 8-OH-dG as they did when sleeping at night.

"This likely reflects a reduced capacity to repair oxidative DNA damage due to insufficient levels of melatonin,” the authors write, “and may result in cells harbouring higher levels of DNA damage."

DNA damage is considered one of the most fundamental causes of cancer.

Lead author Parveen Bhatti says it’s possible that taking melatonin supplements could help, but it’s still too soon to tell. This was a very small study, the participants were all white, and the researchers didn't control for lifestyle-related variables like what the workers ate.

“In the meantime,” Bhatti told Mental Floss, “shift workers should remain vigilant about following current health guidelines, such as not smoking, eating a balanced diet and getting plenty of sleep and exercise.”
