The Romans fashioned their buildings with concrete that has endured for 2,000 years. Their secret? Some researchers think it’s how the Romans heated lime. Others think it’s how they usedpozzolanic material such as volcanic ash. Nowhere does coffee figure into the equation. Too bad.
Happily, researchers at the Royal Melbourne Institute of Technology (RMIT) University have discovered that “concrete can be made 30% stronger by replacing a percentage of sand with spent coffee grounds, an organic waste product produced in huge amounts that usually ends up in landfills,” writes New Atlas. Rajeev Roychand (above), the lead author of a study in the Journal of Cleaner Production, notes: “The disposal of organic waste poses an environmental challenge as it emits large amounts of greenhouse gasses including methane and carbon dioxide, which contribute to climate change. The inspiration for our work was to find an innovative way of using the large amounts of coffee waste in construction projects rather than going to landfills—to give coffee a ‘double shot’ at life.” If Roychand’s research findings endure, archaeologists and materials engineers might enjoy puzzling over the mysteries of coffee and concrete another two millennia from now.

In the fall of 1969, there were still a great many people who’d never heard a synthesizer. And even among those who had, few would have known how its unfamiliar sounds were actually made. Hence the importance of the segment from the BBC program Tomorrow’s World above, which introduced the Moog synthesizer (originally created by Robert Moog) to viewers across Britain. Having come on the market four years earlier, it would go on to change the sound of music — a project, in fact, on which it had already made serious inroads, with such Moog showcases as the Doors’ “Strange Days” and Wendy Carlos’ Switched-on Bachhaving already become cultural phenomena unto themselves.
Manfred Mann would also do his part to make an impact with the Moog. Calling him “the Moog pioneer of rock music,” Fidelity magazine’s Hans-Jürgen Schaal writes that “Mann lent his instrument out to be used to produce the first Moog solo on a record by Emerson Lake & Palmer. He even did the keyboard work himself on the first Moog solo by Uriah Heep.”
It is Michael Vickers, a multi-instrumentalist veteran of Mann’s eponymous band, who demonstrates the Moog for Tomorrow’s World by playing a variety of melodies through it on a keyboard — though not before plugging in a series of patch cords to create just the right electronic sound.
Whether or not the BBC viewers of 1969 had ever heard anything like the Moog before, they almost certainly hadn’t seen anything like it before. Despite looking less like a musical instrument than like a piece of military hardware, it actually represented, like most technological advancements, a step forward in ease of use. As presenter Derek Cooper puts it, the Moog “produces sounds in a matter of minutes which would normally take radiophonic experts with their complicated equipment,” like the BBC’s own Daphne Oram or Delia Derbyshire, “days of work and multiple re-recordings to achieve.” Not that the average hobbyist could afford the Moog seen in this broadcast back then — nor, for that matter, can the average hobbyist afford the $35,000 a faithful re-creation of it costs now.

“If you’re in Venice, you might not enjoy it so much if you follow a tour-guide route that gets you to the main attractions.” So says Youtuber Manuel Bravo — whom we’ve previously featured here on Open Culture for his videos on Pompeii, the Duomo di Firenze, and the Great Pyramids of Giza — in “Venice Explained” just above. “But if you get off that road, the charm of Venice is that it’s such a tangled mess that nobody ventures out there” — out, that is, into the “wonderful little neighborhoods with little squares with cisterns and little cafés.” Diminutive though that may sound, Venice comes off in Bravo’s analysis as an entire, unique urban realm unto itself.
“Historically, Venice is really detached from Italy proper,” Bravo says. “It was not a Roman town. It does not have the detritus of Roman ruins scattered around. It does not have remnants of a Roman town plan with cardo and decumanus. It does not even have, well, land.”
Indeed, Venice is famous for having been built in the Adriatic Sea, on a “new fortified ground plane” made of strong trees imported from Croatia. As its political and economic importance grew, so did its “incomparable medieval urban landscape that has remained practically unchanged.” This built environment is full of architectural styles and details seen nowhere else, to which Bravo draws our attention through the course of the video.
Though he recommends departing from the tourist-beaten paths, he doesn’t ignore such world-famous Venetian structures as the Ca d’Oro, “perhaps the most beautiful building in Venice”; the Doge’s Palace with its “antigravity” architecture; and — in detail — the Basilica and Piazza San Marco, “one of the most memorable spatial complexes in the history of urban planning.” No first visit would be complete without some time spent at each of these sites. But “Venice is a city of light,” and in order properly to enjoy it, we must “see it at different times of the day and experience all the nuances that it offers”: good advice in this “most visually seductive of all the cities in the world,” but also worth bearing in mind as a means of appreciating even the less majestic places in which most of us usually find ourselves.

We know that Michelangelo wrote grocery lists; now we have evidence that Leonardo wrote resumes. “Before he was famous, before he painted the Mona Lisa and the Last Supper, before he invented the helicopter, before he drew the most famous image of man, before he was all of these things, Leonardo da Vinci was an artificer, an armorer, a maker of things that go ‘boom,’ ” writes Marc Cendella on his blog about job-searching and recruitment advice. “Like you, he had to put together a resume to get his next gig. So in 1482, at the age of 30, he wrote out a letter and a list of his capabilities and sent it off to Ludovico il Moro, Duke of Milan.” Having yet to establish his reputation as perhaps the Italian Renaissance’s most respected polymath, Leonardo spelled himself out, in translation, as follows:
Most Illustrious Lord, Having now sufficiently considered the specimens of all those who proclaim themselves skilled contrivers of instruments of war, and that the invention and operation of the said instruments are nothing different from those in common use: I shall endeavor, without prejudice to any one else, to explain myself to your Excellency, showing your Lordship my secret, and then offering them to your best pleasure and approbation to work with effect at opportune moments on all those things which, in part, shall be briefly noted below.
1. I have a sort of extremely light and strong bridges, adapted to be most easily carried, and with them you may pursue, and at any time flee from the enemy; and others, secure and indestructible by fire and battle, easy and convenient to lift and place. Also methods of burning and destroying those of the enemy.
2. I know how, when a place is besieged, to take the water out of the trenches, and make endless variety of bridges, and covered ways and ladders, and other machines pertaining to such expeditions.
3. If, by reason of the height of the banks, or the strength of the place and its position, it is impossible, when besieging a place, to avail oneself of the plan of bombardment, I have methods for destroying every rock or other fortress, even if it were founded on a rock, etc.
4. Again, I have kinds of mortars; most convenient and easy to carry; and with these I can fling small stones almost resembling a storm; and with the smoke of these cause great terror to the enemy, to his great detriment and confusion.
5. And if the fight should be at sea I have kinds of many machines most efficient for offense and defense; and vessels which will resist the attack of the largest guns and powder and fumes.
6. I have means by secret and tortuous mines and ways, made without noise, to reach a designated spot, even if it were needed to pass under a trench or a river.
7. I will make covered chariots, safe and unattackable, which, entering among the enemy with their artillery, there is no body of men so great but they would break them. And behind these, infantry could follow quite unhurt and without any hindrance.
8. In case of need I will make big guns, mortars, and light ordnance of fine and useful forms, out of the common type.
9. Where the operation of bombardment might fail, I would contrive catapults, mangonels, trabocchi, and other machines of marvellous efficacy and not in common use. And in short, according to the variety of cases, I can contrive various and endless means of offense and defense.
10. In times of peace I believe I can give perfect satisfaction and to the equal of any other in architecture and the composition of buildings public and private; and in guiding water from one place to another.
11. I can carry out sculpture in marble, bronze, or clay, and also I can do in painting whatever may be done, as well as any other, be he who he may.
Again, the bronze horse may be taken in hand, which is to be to the immortal glory and eternal honor of the prince your father of happy memory, and of the illustrious house of Sforza.
And if any of the above-named things seem to anyone to be impossible or not feasible, I am most ready to make the experiment in your park, or in whatever place may please your Excellency – to whom I comment myself with the utmost humility, etc.
Even the densest fifteenth-century Duke, I wager, could see the use in a man able to make portable bridges, get water out of trenches, destroy rock built upon rock, fling a storm of stones, fortify vessels, pass under rivers, and make everything from “big guns,” catapults, mangonels, and trabocchi to unattackable covered chariots. Though Leonardo understandably concentrates on his wartime engineering skills, he also touches on the range of other disciplines — Renaissance man, remember — he has mastered, like architecture, sculpture, and painting. Perhaps most impressively of all, he rattles off all these points without seeming particularly boastful. “You’ll notice he doesn’t recite past achievements,” Cendella adds, “because those are about hisachievements, and not about the Duke’s needs.” Still, he might have added that, given just a few more years, he could design a pretty captivating organ.

Who created the first work of abstract art has long been a fraught question indeed. Better, perhaps, to ask who first said of a work of art that a kid could have made it. A strong contender in that division is the Russian artist Véra Pestel, whom history remembers as having reacted to Kazimir Malevich’s 1915 painting Black Square with the words “Anyone can do this! Even a child can do this!” Yes, writes novelist Tatyana Tolstaya a century later in the New Yorker, “any child could have performed this simple task, although perhaps children lack the patience to fill such a large section with the same color.” And in any case, time having taken its toll, Malevich’s square doesn’t look quite as black as it used to.
Nor was the square ever quite so square as we imagine it. “Its sides aren’t parallel or equal in length, and the shape isn’t quite centered on the canvas,” says the narrator of the animated TED-Ed lesson above. Instead, Malevich placed the form slightly off-kilter, giving it the appearance of movement, and the white surrounding it a living, vibrating quality.”
Fair enough, but is it art? If you’d asked Malevich himself, he might have said it surpassed art. In 1913, he “realized that even the most cutting-edge artists were still just painting objects from everyday life, but he was irresistibly drawn to what he called ‘the desert,’ where nothing is real except feeling.” Hence his invention of the style known as Suprematism, “a departure from the world of objects so extreme, it went beyond abstraction.”
Malevich made bold claims for Suprematism in general and Black Square in particular. “Up until now there were no attempts at painting as such, without any attribute of real life,” he wrote. “Painting was the aesthetic side of a thing, but never was original and an end in itself.” As Tolstaya puts it, he “once and for all drew an uncrossable line that demarcated the chasm between old art and new art, between a man and his shadow, between a rose and a casket, between life and death, between God and the Devil. In his own words, he reduced everything to the ‘zero of form.’ ” She calls this zero’s emergence in such a stark form “one of the most frightening events in art in all of its history of existence.” If so, here we have an argument for not letting young children see Black Square and enduring the consequent nightmares — even if they could have painted it themselves.

During the 15th and 16th centuries, fashionable men sported a codpiece. Originally a garment designed to protect and support the proverbial “Willy” (especially when men wore tights), the codpiece morphed into something else–a sign of virility, “a bulging and absurd representation of masculinity itself.” The codpiece featured prominently in paintings by masters such as Titian, Giorgione, Bruegel and Holbein. Above, Evan Puschak (aka the Nerdwriter) introduces you to Holbein’s famous portrait of Henry VIII, “the poster boy for codpieces.”

To get back to the essence of kintsugi, and gain a clearer understanding of its laborious physical nature, it couldn’t hurt to watch a few kintsugists at work. Take Hiroki Kiyokawa, who reflects on his 45 years practicing the art in Kyoto — not without expressing his own ideas about how he feels he’s also “restoring the broken parts of myself” — in the BBC video above.
Or, for a more modern presentation, have a look at this tutorial video from Chimahaga, a kintsugist who not long ago launched his own Youtube channel dedicated to explaining what he does. He’s even uploaded videos about not just kintsugi, (金継ぎ, or “golden joinery”), but also gintsugi (銀継ぎ), which achieves a different but equally striking effect using silver instead of gold.
Kintsugi clearly isn’t a hobby you can master over a few weekends. But you don’t have to be a lifelong Kyoto artisan to benefit from learning it, as emphasized by psychologist Alexa Altman in the video just above. Having learned kintsugi in Japan, she practices it here in a somewhat unconventional way, repairing not pottery damaged over time or by accident, but pottery which she’s smashed on purpose. The bowl, in this case, represents “some aspect of yourself”; the hammer is “an instrument of change”; the glue is “all about connection”; the holes and cracks “can be representations of loss”; the gold is “glory, a celebration.” Whether or not you accept these metaphors, those who practice kintsugi — or any craft demanding such a degree of patience and concentration — surely improve their psychological state in so doing.

It makes sense that Sofia Coppola and Zoe Cassavetes would be friends. Not only are they both respected filmmakers of Generation X, they’re both daughters of maverick American auteurs, a condition with its advantages as well as its disadvantages. The advantages, in Coppola’s case, have included the ability to get Zoetrope, her father Francis Ford Coppola’s production company, to foot the bill for a project like Hi-Octane: in the words of a 1994 W magazine profile, “a non-talk show in which Sofia and Zoe drive around and interview cool people, essentially their friends” — a group that included Keanu Reeves, Martin Scorsese, Gus Van Sant, and the Beastie Boys.
Coppola and Cassavetes didn’t do all the interviewing themselves. Their correspondents included the photographer Shawn Mortensen, whom they sent off to Paris Fashion Week to talk to the likes of Naomi Campbell, Karl Lagerfeld, and André Leon Talley, and Sonic Youth’s Thurston Moore, who hosted his own regular segment. “Thurston’s Alley” was usually shot literally there, in the alley alongside the building where he lived in New York, and, to it, he lured guests like Johnny Ramone and Sylvia Miles. But in one very special episode, he visits the Condé Nast building to interview none other than Anna Wintour — and, in one of the moments Hi-Octane’s viewers have never forgotten, to describe the mayonnaise-based hair styling technique of Pixies Bassist Kim Deal.
“I wrote the script ’cause I was so into cars,” the young Coppola told W. “And I have access to all these interesting people — these actors and musicians. But when you see them interviewed on television, they just talk about their characters and it’s so boring. The sets are always hideously ugly. TV people always say they want to cater to people my age, but they have no idea how to do it. So we just wanted to incorporate the things we’re interested in — cars, painting, music.” In one episode, she and Cassavetes take monster-truck lessons; in another, she gets a bass lesson from the Minutemen’s Mike Watt; another features an extended profile of psychedelo-sexual-apocalyptic painter Robert Williams, whom Coppola’s cousin Nicolas Cage turns up to praise as “a modern-day Hieronymus Bosch.”
Hi-Octane aired at 11:00 at night on Comedy Central, a time slot between Whose Line Is It Anyway? and Saturday Night Live. It only did so three times before its cancellation, but each of those broadcasts offers a strong if somewhat makeshift distillation of a certain mid-nineties Gen‑X sensibility, whose outward smirking disaffection is belied by its overpowering subcultural enthusiasm and sense of fun. “I wouldn’t change it because part of the sloppiness makes it unique and what it is,” Coppola said in a more recent interview. “I think if anything has sincerity and heart, this is it.” She may have known even at the time that it was all too pure to last. “Comedy Central says our show’s not funny enough,” she says to Cassavetes at the end of the second episode. “I think it’s funny that they gave us a show,” Cassavetes replies, and Coppola has to give it to her: “That is… that is funny.”
