Tiles In Motion

Lawrence Weschler at Wondercabinet:

I won’t go into the history of the tiling problem here—Roberts does her typically clear, concise, and beguiling job in the article in question, well supplemented by an equally captivating account offered by longtime friend of the Cabinet, Margaret Wertheim, in a recent issue of her new substack Science Goddess, which you can find here. I love it that when it came to a breakthrough that had eluded the likes of the eminent Nobel laureate Roger Penrose (Stephen Hawking’s mentor!), who’d gotten stuck several years back one step shy of this ultimate solution, the fellow who turned out to make the decisive leap proved to be a modest, self-effacing cypher and complete nonprofessional outsider by the (near-perfectly anonymous) name of David Smith, who’d then had to seek out a small band of intrepid professionals to frame the discovery in terms a peer-reviewed journal would countenance (at first none of them could quite believe the development either). But that’s how it sometimes (even if almost never) happens. So do yourselves a favor and bone up on the particulars of this magical discovery on your own.

The Lives and Deaths of Shakespeare’s First Tragic Heroine

Kirsten Tambling at Literary Review:

In 1611, the Somerset-born traveller Thomas Coryat described an Italian architectural novelty: a ‘very pleasant little tarrasse, that jutteth or butteth out from the maine building: the edge whereof is decked with many pretty little turned pillers … to leane over’. England’s introduction to the balcony came over a decade after the first performance of William Shakespeare’s tragedy Romeo and Juliet. When it was staged in the summer of 1596, just before London’s playhouses were closed owing to a resurgence of plague, the exchange now universally known as the ‘balcony scene’ was probably transacted at a window opening onto the backstage ‘tiring house’ of the Shoreditch Theatre. The popular image of Juliet as a bright-eyed teenager in white muslin leaning over a balustrade only began to form a century and a half later, when a balcony first appeared as part of the stage set. By the late 1930s, the museum director Antonio Avena had improvised a ‘tarrasse’ from a marble sarcophagus and retrofitted it to the walls of Via Cappello 23 – putative home of the ‘historical’ Capulets in Verona. Visitors now pose on ‘Juliet’s balcony’ as part of an international pilgrimage that also includes visiting a bronze statue of Shakespeare’s heroine and rubbing her right breast for luck.

Hanif Kureishi to publish memoir about accident that left him paralysed

Lucy Knight in The Guardian:

The novelist and screenwriter Hanif Kureishi is to publish a memoir about the accident that left him paralysed last year, expanding on the brutally honest material the author has been sharing on social media and online platform Substack, which he continues to dictate from an Italian hospital.

On Boxing Day 2022, the author of The Buddha of Suburbia was rushed to intensive care after a fall in Rome. He later tweeted, via dictation to family, that he may never be able to walk or use a pen again.

“I cannot scratch my nose, make a phone call or feed myself,” he wrote.

Since then his blogposts, The Kureishi Chronicles, and his tweets have shared insights on everything from his health to his recreational drug use. A recent post told of a visit from his schoolfriend David, whom Kureishi revealed he had fancied in his youth.

Comb jellies have a bizarre nervous system unlike any other animal

Jake Buehler in Science News:

Shimmering, gelatinous comb jellies wouldn’t appear to have much to hide. But their mostly see-through bodies cloak a nervous system unlike that of any other known animal, researchers report in the April 21 Science.

In the nervous systems of everything from anemones to aardvarks, electrical impulses pass between nerve cells, allowing for signals to move from one cell to the next. But the ctenophores’ cobweb of neurons, called a nerve net, is missing these distinct connection spots, or synapses. Instead, the nerve net is fused together, with long, stringy neurons sharing a cell membrane, a new 3-D map of its structure shows.

The Dao of Using Your Smartphone

Alan Levinovitz in The Hedgehog Review:

Screentime limitsDinner table lockboxesMinimalist devices. There’s no shortage of creative fixes for our broken relationship to smartphones. Consumption is the enemy, restriction is the solution, and new habits are the promised result. The goal? A more productive life, free from useless scrolling and hollow social media.

Unfortunately, this approach has serious drawbacks. Like a traditional diet, it requires endless vigilance and it pathologizes the target of restriction. More importantly, the goal reinforces the same values that tether us to our phones in the first place: productivity and utility.

As a professor of classical Chinese thought who has struggled with my devices, I follow a different approach inspired by Confucianism and Daoism.

Parrots Video Calling Other Parrots

Schuyler Velasco at Northeastern Global News:

The researchers then observed how the birds used that newfound ability over a three-month period. They wondered: If given the choice, would the birds call each other?

The answer, relayed in delighted squawks and head bobs, was a resounding yes. “Some strong social dynamics started appearing,” Kleinberger says.

Not only did the birds initiate calls freely and seem to understand that a real fellow parrot was on the other end, but caretakers overwhelmingly reported the calls as positive experiences for their parrots. Some caregivers watched their birds learn skills from their video friends, including foraging, new vocalizations and even flying. “She came alive during the calls,” reported one. A few significant findings emerged. The birds engaged in most calls for the maximum allowed time.

Tuesday Poem

Praise of Learning

Learn the simplest things. For you
whose time has already come
it is never too late!
Learn you’re A B C’s, it is not enough,
but learn them! Do not let it discourage you,
begin! You must know everything!
You must take over the leadership!

Learn, man in the asylum!
Learn, man in prison!
Learn, wife in the kitchen!
Learn, man of sixty!
Seek out the school, you who are homeless!
Sharpen your wits, you who shiver!
Hungry man, reach for the book: it is a weapon.
You must take over the leadership.

Don’t be afraid of asking, brother!
Don’t be won over,
see for yourself!
What you don’t know yourself,
you don’t know.
Add up the reckoning.
It’s you who must pay it.
Put you finger on each item,
ask: how did this get here?
You must take over the leadership.

Immunity Is a Matter of Timing

Diana Kwon in Nautilus:

Jane McKeating never expected time to matter much in the liver.

About a decade ago, McKeating was examining medications to use during liver transplantation in patients with chronic hepatitis C infections. Hepatitis C can linger in the body for decades and cause severe liver damage—and in those days, the lack of drugs to combat the viral infection meant that when a patient received a replacement liver, the virus could immediately infect the new organ. McKeating, then a virologist at the University of Birmingham in the United Kingdom, and her colleagues wanted to see whether an antiviral drug could stop the virus’ spread and save the new livers.

When the team initially assessed their data, they were stumped. It looked like the drug prevented infection in some patients, but not others—and it wasn’t clear what, exactly, was behind this difference. “We just couldn’t understand what was discriminating between the patients,” says McKeatin, now at the University of Oxford. After much head scratching, they noticed a perplexing pattern: Patients who received their liver transplants in the morning were more likely to be reinfected with the hepatitis C virus than those who had their operations in the afternoon.1 “It turned out it was the time of day when they received the liver transplant,” she says.

A new theory of embodied consciousness

Forget ‘I think therefore I am’. In a new theory of embodied consciousness, the neuroscientists Antonio Damasio and Hanna Damasio propose that feelings are the source of consciousness. Long dismissed as secondary to reason, feelings are where consciousness begins. Without them, consciousness is impossible, they argue – with radical implications for the ‘hard problem’ of consciousness and the future of AI.

Antonio Damasio and Hanna Damasio at IAI News:

Please pause for a moment and notice what you are feeling now. Perhaps you notice a growing snarl of hunger in your stomach or a hum of stress in your chest. Perhaps you have a feeling of ease and expansiveness, or the tingling anticipation of a pleasure soon to come. Or perhaps you simply have a sense that you exist. Hunger and thirst, pain, pleasure and distress, along with the unadorned but relentless feelings of existence, are all examples of ‘homeostatic feelings’. Homeostatic feelings are, we argue here, the source of consciousness.

A New Kind of Symmetry Shakes Up Physics

Kevin Hartnett in Quanta:

It’s not an exaggeration to say that every major advance in physics for more than a century has turned on revelations about symmetry. It’s there at the dawn of general relativity, in the birth of the Standard Model, in the hunt for the Higgs.

For that reason, research across physics is now building to a crescendo. It was touched off by a 2014 paper, “Generalized Global Symmetries,” which demonstrated that the most important symmetries of 20th-century physics could be extended more broadly to apply in quantum field theory, the basic theoretical framework in which physicists work today.

This reformulation, which crystallized earlier work in the area, revealed that disparate observations physicists had made in the past 40 years were really manifestations of the same lurking symmetry. In doing so, it created an organizing principle that physicists could use to categorize and understand phenomena. “That’s really a stroke of genius,” said Nathaniel Craig, a physicist at the University of California, Santa Barbara.

Ellen O’Brien on Driving

Ellen O’Brien in the Sydney Review of Books:

When I’m driving my car, I feel like I’m in my own private domicile, bitch! I’m the driver, so I’m in control: I choose the music, the temperature level, how fast or slow we go. I also suffer the consequences, but that’s fine—it’s my life! And yes, there are things I should consider—agreements between us, called ‘road rules’ and ‘traffic laws’—but if I disregard them, I can pretend that I’m the queen of my own little castle. So, vroom fucking vroom, baby! Let’s ride.

“Luxury” construction causes high rents like umbrellas cause rain

Noah Smith in Noahpinion:

Imagine if you went outside and saw that it had started to rain, and that people on the street were opening their umbrellas. And imagine that you ran around waving your arms and saying “Stop! Stop! Umbrellas make rain worse!!” People would think you were a silly person, and rightly so.

But why don’t people think that umbrellas make rain worse? After all, everyone knows that rain typically starts to intensify shortly after people start opening their umbrellas. But we have a good causal theory of why rain happens, and we know that umbrellas have nothing to do with it; we know that the umbrellas are a response to the problem, rather than the cause.

The same should be true for market-rate housing construction and rising rents.

Imran Khan on His Plan to Return to Power

Charlie Campbell in Time:

Political leaders often boast of inner steel. Imran Khan can point to three bullets dug out of his right leg. It was in November that a lone gunman opened fire on Khan during a rally, wounding the 70-year-old as well as several supporters, one fatally. “One bullet damaged a nerve so my foot is still recovering,” says the former Pakistani Prime Minister and onetime cricket icon. “I have a problem walking for too long.” The actual intrigue is purely Pakistani. Khan lost the backing of the country’s all-powerful military after he refused to endorse its choice to lead Pakistan’s intelligence services, known as ISI, because of his close relationship with the incumbent. When Khan belatedly greenlighted the new chief, the opposition sensed weakness and pounced with the no-confidence vote. Khan then took his outrage to the streets, with rallies crisscrossing the nation for months.

India’s Beef with Beef

Sharanya Deepak in The Baffler:

WHEN JUNAID KHAN was a young boy, his mother, Saira Begum, would return home close to nightfall. She would squat next to an open fire to cook rotis for her hungry son, who would smear them with butter. “Junaid would eat rotis in whole gulps. I had to stop him before he ate too much,” Saira told me one summer evening in 2019. She lives with her relatives in a small brick house in Khandawali, a village in Haryana near New Delhi. When we spoke, she lay on her divan. In a corner stood a desk on which Junaid would study. Like many women in her village, Saira is a farm laborer whose income—four thousand rupees per month in 2019, or fifty-seven dollars—does not ensure food for her family at all times. She owns one buffalo, however, that she milks and uses to plow the land that she works. Food is scarce in her home, but the white butter she made with buffalo milk was delicious and filling for her children.

Junaid was sixteen years old when he, his older brother Hashim, and two friends were attacked on a train in Haryana in June 2017. The boys were commuting home from an Eid shopping trip and a visit to the mosque when they were asked to vacate their seats by a group of men. When I visited Saira’s home, Hashim explained that the men noticed they were Indian Muslims and threatened to beat them if they didn’t move. “They were older, larger, and Hindu,” he recounted, as he fiddled with a photograph of Junaid. “They kept calling us beef eaters,” he continued, along with other faith-based slurs.
