From Lindsay Holiday, an engaging history of birth control, covering the ineffective and often dangerous methods used in the ancient world, the rhythm method, proto-condoms, actual condoms, Lysol (!!), and of course one of the modern world’s most impactful inventions, the hormonal birth control pill.
Through most of history pregnancy and childbirth were a very dangerous undertaking for women. In medieval Europe 1 in 3 women died in their child-bearing years and 1 in 4 children did not live to see their first birthday. Even when both mother and child survived the ordeal of birth women were not always able to provide for a child. And in most cultures pregnancy outside of wedlock was considered a great sin and often resulted in the shunning of the woman and child while the man often got away scot-free. It is no surprise therefore that women throughout history have been trying a wide variety of methods to prevent conception.
There is something deeply soothing to the human brain, at least to this human brain, about watching liquids flow. A burbling brook, cascading waterfall, crashing waves. Even better when it looks like outer space, like this video by Vadim Sherbakov of wonderfully whirling colorful inks with glitter. (via colossal)
In the small Chinese village of Nuanquan, they make fireworks displays by throwing molten iron against the wall, which causes it to explode in a shower of sparks.
For the past 30 years, Wang De has been practicing the ancient art of Da Shuhua, a 500-year-old tradition that first began with blacksmiths in the Nuanquan village of China. Wanting a way to celebrate Chinese New Year, but without the means to afford traditional fireworks, these blacksmiths devised a new form of entertainment. By tossing molten iron against the walls, they created beautiful showers of sparks, beginning a practice that would soon become a part of their cultural heritage. Now, it’s a special part of Nuanquan’s legacy as there’s no place else on Earth to witness the fiery spectacle.
This would be something to see in person — thousands of tiny sparks flying around at great speeds is exactly the sort of thing that compressed online video doesn’t depict that well.
I saw Everything Everywhere All At Once a few weeks ago and absolutely loved it — best movie I’ve seen all year and I can’t remember having a better time seeing a film in the theater in the past 3-4 years. So watching this short making-of featurette of Michelle Yeoh and the Daniels was really nice. It’s not surprising how thoughtful yet open to creative chaos they are, given the magic of the end result.
In the last installment of a video series called The Universe in Verse, Maria Popova, Yo-Yo Ma, and Kelli Anderson have collaborated on a video that features words spoken by Nobel Prize-winning physicist Richard Feynman in a 1955 speech, a poem of sorts on the wonder of life.
Deep in the sea, all molecules repeat the patterns of one another till complex new ones are formed. They make others like themselves… and a new dance starts.
Growing in size and complexity… living things, masses of atoms, DNA, protein… dancing a pattern ever more intricate.
Out of the cradle onto the dry land… here it is standing… atoms with consciousness… matter with curiosity.
Lovely. And of course I love the visuals by Kelli Anderson.
As part of her Circuit Garden project, artist Kelly Heaton makes birds out of electronic circuitry that can be adjusted to produce a wide variety of birdsong. Here she demonstrated with a printed circuit bluejay:
As Heaton explains, the sounds made by the birds aren’t recordings…they’re generated by the electronics, like a synthesizer.
My “printed circuit birds” are self-contained sound generators. The electronics are [100%] analog: no audio recordings or software are involved. By “analog” I mean that the sound is dynamically produced by the bird’s body (circuit), like a vintage synthesizer. In this video, I adjust knobs to change resistance in the circuit, thereby altering the song quality. You can think of this like adjusting neurons in a bird’s brain to alter the impulse by which it vocalizes.
Regarding flat track racing on the moon, I would prefer some big gaps and jumps more than turning left around an oval. With almost one-sixth of Earth’s gravity, I’d need only a small bump to jump 10 meters — that would be fun! Maybe the Tardigrade inspires space-addicted people and engineers for upcoming lunar missions, and I would be more than happy to be a tiny part of that.
You may have noticed, while twisting apart Oreos (aka the world’s favorite “trilayer laminate composite”) to get at the creme inside, that the creme tends to mostly stick to one half of the cookie. MIT graudate student Crystal Owens decided to study this phenomenon and has co-authored a paper about the failure mechanics of the Oreo’s layer of creme in the journal Physics of Fluid. From Ars Technica:
“I had in my mind that if you twist the Oreos perfectly, you should split the creme perfectly in the middle,” said Owens. “But what actually happens is the creme almost always comes off of one side.” The experiments showed that this creme distribution is not affected by rotation rate, the amount of creme filling, or the flavor. Rather, the pre-existing level of adhesion between the creme and the chocolate wafers seemed to be the determining factor. Cookies from the package within any one box typically separated with the same preferred orientation most of the time. This suggests that it has something to do with how the cookies are manufactured and then oriented during packaging, as well as how they are stored.
They even built a 3D printed “oreometer” so that people can study this phenomenon without using an expensive rheometer.
As a very amateur kitchen scientist myself, the Oreo situation reminds me of what happens when you try to tear three connected pieces of paper towel apart in one move by pulling on the outside pieces in opposite directions: the middle piece of paper towel almost always ends up attached to one of the outside pieces. In fact, in extensive testing over the past 3-4 years, this maneuver has only separated all three pieces a few times.1 (thx, eric)
There’s always a lot of hootin’ and hollerin’ and victory laps around the kitchen when a perfect pull happens. It’s a rare event!↩
Wow, NASA just released a video shot by the Mars Perseverance rover of a solar eclipse by the moon Phobos. The video description calls it “the most zoomed-in, highest frame-rate observation of a Phobos solar eclipse ever taken from the Martian surface”. According to this article from JPL, the video of the eclipse is played in realtime; it only lasted about 40 seconds.
Captured with Perseverance’s next-generation Mastcam-Z camera on April 2, the 397th Martian day, or sol, of the mission, the eclipse lasted a little over 40 seconds — much shorter than a typical solar eclipse involving Earth’s Moon. (Phobos is about 157 times smaller than Earth’s Moon. Mars’ other moon, Deimos, is even smaller.)
Just a hunk of space rock passing in front of a massive burning ball of gas recorded by a robot from the surface of an extraterrestrial planet, no big deal.
Seán Doran strikes again. In this short flyover rendered in 8K resolution by Doran, we’re treated to a detailed look at a crater on Mars. The imagery is from the HiRISE camera onboard the Mars Reconnaissance Orbiter. Beautiful — worth taking a second or third pass to catch all the details.
From the Brick Technology YouTube channel, a demonstration on how to build a 5-speed manual transmission with Lego. It even has a gear stick and goes in reverse. Unloaded, 1st gear spins an axel at 384 rpm and 5th gear spins at 3000 rpm. Really impressive.
Because of their relevance to social media, the algorithm has become an everyday concept. Why do we see the posts we see on Instagram or TikTok? Oh, it’s the algorithm. This video from BBC Ideas explains that the term has its roots in the work of 9th century Persian mathematician Muḥammad ibn Mūsā al-Khwārizmī, who also gave the world the word “algebra”. (via the morning news)
I had always heard that the engineering of Roman aqueducts was impressive, but as this video demonstrates, I didn’t know the half of it. The stuff about how precise the descending slope of the aqueducts were over several hundred miles is just incredible. (via open culture)
Is there a physical limit to how loud a noise can be? As you might imagine, the answer is somewhat complicated, even if you assume normal atmospheric conditions. In video, Benn Jordan discusses a few possible answers, as well as how we should think about the question in the first place. One possible answer is 194 decibels, although experiencing a sound that loud would probably kill you.
See also The World’s Loudest Sound, aka the sound generated by the Krakatoa volcanic eruption in 1883, which Jordan mentions in the video.
The Thin Blue Line got Randall Adams out of jail after 12 years. Blackfish almost bankrupted Seaworld and pressured them to end their orca breeding program. Making A Murderer almost got Brendan Dassey out of jail. But in this video essay, Eliz Mizon “argues that documentaries start conversations, but they can’t spark real change.”
Just how do haboobs form? When air is forced down and pushed forward by the front of a traveling thunderstorm cell, it drags with it dust and debris. Winds of speeds up to 60 mph can stir up dust and sand and create a blowing wall as high as 10,000 feet. Haboobs usually last only 10 to 30 minutes, but on rare occasions can last longer and create hazardous conditions for ground transportation systems, air traffic and motorists.
I have to admit: before watching this video, I was unaware that there were professional jump ropers. But of course there are, and Tori Boggs is perhaps the best one in the world. She’s won dozens of world championships and holds some impressive world records. And the tricks she can do with a rope…it’s a joy to watch someone who so obviously loves what they do perform at such a high level. (via the kid should see this)
Actually, my first article of warning was published in “The Wall Street Journal” on January 4, 2001. I saw evil because I heard evil. Putin was telling us what he was. All we had to do was listen. When Putin said that there was no such thing as a former KGB agent, I knew Russia’s fragile democracy was in danger. When Putin said that the collapse of the Soviet Union was the greatest geopolitical catastrophe of the 20th century, I knew Russia’s newly independent neighbors were at risk. And when Putin talked at the Munich Security Conference in 2007 about a return to spheres of influence, I knew he was ready to launch his plan. It was the language from the Molotov-Ribbentrop Pact, 1939. The language Hitler and Stalin used to divide Europe. And a year later, in 2008, Putin invaded the Republic of Georgia. 2014, Ukraine.
It’s a paradox, isn’t it? Dictators lie about everything they have done, but often they tell us exactly what they’re going to do. Just listen. Anyone who is surprised at Putin’s war crimes in Ukraine must not be aware about his long record, beginning with the Second Chechen War in Grozny more than two decades ago. Vladimir Putin has been a war criminal from the start.
When he was talking about the problem with compromising with authoritarians, I was reminded of a phrase I’ve heard in a couple of different contexts recently: meeting a racist halfway on their views is still racism; meeting a fascist halfway on their views is still fascism. As Rebecca Solnit put it in an article about the 2020 election: “Who the hell wants unity with Nazis until and unless they stop being Nazis?” Meeting a brutal authoritarian halfway, Kasparov is arguing, is still tyranny.
The port of Amsterdam is one of the busiest seaports in Europe. But it gets really busy when there are tall ships from all over the world and everyone wants to get out on the water to see them. This is a time lapse video taken at the 2015 SAIL maritime festival that shows the port absolutely teeming with ships and boats of all shapes and sizes.
Building on the lessons of World War II, Ukrainians are trying to save their art and other important cultural artifacts from destruction during Russia’s invasion. When an invader repeatedly tries to deny the cultural distinction of a people for decades and even centuries, like Russia has done with Ukraine, saving buildings and statues and paintings can be of great importance.
Because under the 1954 convention, “damage to cultural property means damage to the cultural heritage of all mankind”. So attacks on cultural heritage are a considered war crime. But treaties can only do so much. In the years since, conflicts around the world have rendered immeasurable damage to cultural heritage. A lot of it intentional. Like the Taliban’s destruction of the Bamiyan buddhas. And Isis’ attacks on ancient sites all over Syria.
“That cultural heritage is not only impacted, but in many ways it’s implicated and central to armed conflict. These are things that people point to that are unifying factors for their society. They are tangible reflections of their identity.”
And Putin has made it clear that identity is at the ideological center of Russia’s invasion: “I would like to emphasize again that Ukraine is not just a neighboring country for us. It is an inalienable part of our own history, culture, and spiritual space.”
“He thinks that we don’t really exist and they want to destroy all the signs of our identity.”
BTW, regarding the destruction of the museum that housed works by Maria Prymachenko at the start of the video: according to the Ukrainian Institute, the works were saved from burning by local residents.
When you think about TV shows about the workplace, The Office is likely top of mind. So, cutting an intro to new workplace darling Severance to match the visual style of The Office intro with The Office theme song was going to happen eventually…and here it is. Nicely done.
Dean Fleischer-Camp and Jenny Slate are turning the subject of their series of short films into a feature length movie. Marcel The Shell With Shoes On, shot in a mockumentary style, features the titular character searching for his family. The trailer is very cute. Here’s the original short, from 2010. (via cool stuff ride home)
In the early 1930s, desiring the bountiful wheat harvests of its farmlands to sell to Europe and wanting to subjugate its people, Soviet dictator Joseph Stalin carried out a genocide in Ukraine that killed millions and hid it behind the guise of food shortages. It’s known as the Holodomor.
In Ukraine, it’s become known as “the Holodomor,” meaning “death by starvation.” It was a genocide carried out by a dictator who wanted to keep Ukraine under his control and who would do anything to keep it covered up for decades.
In the 1930s, Soviet leaders under Joseph Stalin engineered a famine that killed millions as they sought to consolidate agricultural power. In Ukraine, they used additional force as they sought to clamp down on a burgeoning Ukrainian national identity. There, at least 4 million died. As hunger spread among residents, Stalin spearheaded a disinformation campaign to hide the truth from other Soviet citizens and the world. So many Ukrainians died that officials had to send people to resettle the area, setting off demographic shifts that last to this day.
A new video from Kurzgesagt is designed to provide a little hope that humans can figure a way out of the climate crisis, without being overly pollyannish.
And so for many the future looks grim and hopeless. Young people feel particularly anxious and depressed. Instead of looking ahead to a lifetime of opportunity they wonder if they will even have a future or if they should bring kids into this world. It’s an age of doom and hopelessness and giving up seems the only sensible thing to do.
But that’s not true. You are not doomed. Humanity is not doomed.
There’s been progress in the last decade, in terms of economics, technology, policy, and social mores. It’s not happening fast enough to limit warming to 1.5°C, but if progress continues, gains accumulate, people keep pushing, and politicians start to figure out where the momentum is heading, we can get things under control before there’s a global apocalypse.
I don’t know why I thought that chefs at really high-end restaurants cut onions the same way I do at home (except perhaps more carefully), but it turns out that they absolutely do not. The rationale behind the fussiness makes sense: the pieces need to be small enough to “melt away” when you’re making sauces. (via digg)
If you’ve seen a superhero film in the past 10-15 years, chances are that when you see a character wearing a suit, what you’re seeing is almost 100% computer generated. Sometimes the character on the screen is motion-captured but sometimes it’s completely animated. It’s amazing how much these movies are made like animated movies — they can make so many different kinds of changes (clothes, movements, body positioning) way after filming is completed. (via @tvaziri)
I have been really in my feelings lately — about relationships, work, parenting, the general state of the world, and my own bullshit — and well, this video meditation by Hank Green was really lovely to watch with my emotional thermostat turned up to 11. He called the video “I Don’t Have a Good Title for This Video” and I don’t really have a good way to describe it either, so maybe just take 4 minutes and watch it? (via waxy)
This drone fly-through of Tesla’s new factory in Berlin is amazing. I’ve never seen anything quite like this — the drone flies through the robotic machinery in between cycles of stamping out parts and also through the cars as they are being assembled. A uniquely effective how-things-are-made video.
While reviewing some old film footage of a 1970 teacher’s strike stored in the archives of WCCO in Minneapolis, a production manager stumbled across an amazing artifact: a brief interview with Prince. I love when they show the clip to his childhood friends for confirmation that it’s actually him. (via, who else, anil)
Short as the interview is, it gives context to the causes Prince would later support, such as public education, labor rights and fair compensation for artists, said Elliott H. Powell, a professor of American Studies at the University of Minnesota who teaches a course on Prince.
The interview with the young Prince was conducted in north Minneapolis, a predominantly Black part of the city where young activists led uprisings in the 1960s protesting police brutality, the harassment of young Black people in white-owned businesses, and commercial development that was decimating the neighborhood, Professor Powell said.
“Prince is growing up in that environment and seeing the impact of Black youth activists,” he said.
Francis Ford Coppola, a legendary filmmaker no matter how you slice it, sat down recently to talk through his most notable films: The Godfather films, The Conversation, Apocalypse Now, and a new movie he’s working on called Megalopolis. I really enjoyed this. Some tidbits:
Coppola didn’t know anything about the Mafia before making The Godfather.
The studio did not want to call it Godfather Part II. And now explicit sequels like that are ubiquitous.
He praised the way Marlon Brando thought about ants and termites?!
I’d missed that Godfather Part III had been recently recut and rechristened “Mario Puzo’s The Godfather, Coda: The Death of Michael Corleone”, which is what Coppola wanted to call it all along.
And this is a great way to think about creative projects:
Learning from the great Elia Kazan, I always try to have a word that is the core of what the movie is really about — in one word. For “Godfather,” the key word is succession. That’s what the movie is about. Apocalypse Now,” morality. “The Conversation,” privacy.
