From John Koenig’s Dictionary of Obscure Sorrows:

Sonder: The realization that each random passerby is living a life as vivid and complex as your own—populated with their own ambitions, friends, routines, worries and inherited craziness—an epic story that continues invisibly around you like an anthill sprawling deep underground, with elaborate passageways to thousands of other lives that you’ll never know existed, in which you might appear only once, as an extra sipping coffee in the background, as a blur of traffic passing on the highway, as a lighted window at dusk.

The Lou Reed-loving Czech rock group The Plastic People of the Universe may well be the only covers band to ever alter the course of history. After tanks from the Warsaw Pact countries rolled into Prague in 1968, curtailing the liberalising and reformist Alexander Dubček, bands were told to play on, but only if they didn’t have long hair or sing in English. The Plastics, with their unshorn locks, bohemian ways and repertoire of Velvet Underground and Frank Zappa songs, proved to be a thorn in the side of the Soviets. Members and fans of the band were put on trial in 1976, leading playwright Václav Havel and others to write the Charter 77 manifesto and organise protests that shamed the government into lightening the band members’ sentences. When Reed went to interview Havel for Rolling Stone in 1990, he was left stunned when the statesman said to him: “Did you know that I am president because of you?”

Does Albert Einstein’s first wife deserve some credit for relativity?

While her husband, Albert Einstein is celebrated as perhaps the best physicist of the 20^th century, one question about his career remains: How much did his first wife Mileva contribute to his groundbreaking science? While nobody has been able to credit her with any specific part of his work, their letters and numerous testimonies presented in the books dedicated to her provide substantial evidence on how they collaborated from the time they met in 1896 up to their separation in 1914. We will never know. But nobody made it clearer than Albert Einstein himself that they collaborated on special relativity when he wrote to Mileva on 27 March 1901: “How happy and proud I will be when the two of us together will have brought our work on relative motion to a victorious conclusion.”

Mary Godwin and her lover Percy Bysshe Shelley travelled to Europe in 1816, and went to Geneva, to stay with Lord Byron. That year was remarkable for being the “year without a summer.” In 1815 there was a large volcanic eruption of Mount Tambora on the Indonesian island of Sumbawa. Clouds of volcanic ash were propelled into the upper atmosphere, obscuring the sun. The Northern hemisphere saw crop failures, food shortages and sudden climatic change. At the time many were unaware of the causes of this strange phenomenon, and it was common to have to light candles in the middle of the day due to the darkness. Mary and her companions found themselves unable to enjoy the outdoors and instead spent their time inside discussing science, politics and literature. Eventually Byron suggested a ghost story writing competition. And thus, Frankenstein was born.

What happens when a philosopher falls in love

Agnes Callard calls herself a “public philosopher,” which means she applies philosophical thinking to every aspect of her life — including falling in love with a student, divorcing her husband and then living with both of them at the same time. Agnes views romantic relationships as the place where some of the most pressing philosophical problems surface in life, and she tries to “navigate the moral-opprobrium reflexes in the right way,” so that people won’t dismiss the topic as unworthy of public discussion. “If you’re a real philosopher,” she said, “you don’t need privacy, because you’re a living embodiment of your theory at every moment, even in your sleep.” Jonathan Lear, a philosopher at the University of Chicago, said Agnes approaches every conversation as if it were integral to her life’s work, as it was for Socrates. “She’s attempting to live a philosophical life, and this includes taking responsibility for the very concept of marriage.”

Social media is known for producing drama. In Twitter’s case, that’s been true as much behind the scenes as on the platform of late. On Monday, the service was hit by the latest in a series of glitches; this one made it impossible for users to post images, and also triggered a popup error about the company’s application programming interface, or API, whenever someone clicked on a link. Casey Newton and Zoë Schiffer later reported, in the Platformer newsletter, that the glitch was the result of a lone engineer making a mistake while trying to restrict free access to Twitter’s API—a decision that the company recently announced, sparking frustration among researchers and journalists who depend on access to the API for their work. Then, on Tuesday, Elon Musk, who acquired Twitter last year for forty-four billion dollars, got into a public spat with Haraldur Thorleifsson, an employee who said he wasn’t sure if he’d just been laid off, with Musk accusing Thorleifsson of doing no work and pretending to have a disability.  Thorleifsson has multiple dystrophy and is in a wheelchair, and in the past has been named Iceland’s Person of the Year. (Musk later apologized to Thorleifsson, who, Musk said, is now “considering remaining at Twitter.”)

Also on Tuesday, the Wall Street Journal reported that the Federal Trade Commission has demanded that Twitter turn over any internal communications related to Musk, as well as detailed information about staff layoffs; according to documents seen by Ryan Tracy, a Journal reporter, the FTC cited “concerns that staff reductions could compromise the company’s ability to protect users.” In letters sent to Twitter and its lawyers since Musk’s acquisition of the company, the FTC also asked the company to identify all journalists who have been granted access to company records. This appears to be a reference to the “Twitter Files,” reports from a number of journalists, including Matt Taibbi and Bari Weiss, that were based on internal documents that Musk’s Twitter provided to them, and alleged censorship and other improprieties by Twitter’s former management. According to the Journal, the FTC is also seeking to depose Musk.

Musk responded to Monday’s technical glitches by saying that “a small API change had massive ramifications. The code stack is extremely brittle for no good reason. Will ultimately need a complete rewrite.” After the recent housecleaning in which thousands of employees were laid off, Musk demanded that those left at the company commit to his “extremely hardcore” vision, which would see them work for “long hours at high intensity,” or be forced out. Between October, when Musk took control of Twitter, and late January, about eighty percent of full-time workers left the company, Engadget reported, leaving it severely understaffed in some areas. A former employee told the Washington Post that at least six critical systems at Twitter—“like ‘serving tweets’ levels of critical,” the former staffer said—“no longer have any engineers” associated with them. Twitter now has about two thousand employees, down from seven thousand five hundred when Musk took over.

In 1950, Johnny Cash was 18 years old. Looking for independence and a sense of purpose, Cash enlisted in the Air Force and was quickly shipped off to San Antonio, Texas, where he was stationed at the Lackland Air Force base. On March 5th, 1953, Staff Sgt Cash was manning his post when he intercepted an important communique from the Soviets. He hastily transcribed a message explaining that Joseph Stalin was in poor health. For the Americans, the health of the Soviet leader was of critical importance to both the military and intelligence services. Cash continued transcribing morse code messages until he received word that Stalin had been pronounced dead. He relayed the message to his superiors, who in turn relayed it to President Eisenhower.

Plutonium is the deadliest substance known to man. Or is it?

Plutonium is the most dangerous substance known to man. We know this because Walter Cronkite told us so. Cronkite was the dean of network broadcasters and one of the most trusted voices in America. Ralph Nader, a few years earlier, told us just how dangerous. Nader said in a speech at Lafayette College in 1975 that a pound of plutonium could kill eight billion people. But Galen Winsor worked at the US plutonium production plant at Hanford, Washington, for 15 years, and the staff there regularly carried around lumps of highly enriched plutonium in their lab coat pockets. What Nader and the other claimants almost always forget to mention is that plutonium is an alpha-particle emitter. Alpha is a form of radiation that has almost no penetrating power. Alpha particles will be stopped by a piece of paper or a few centimeters of air.

Researchers found that they could reconstruct high-resolution and highly accurate images from brain activity by using the popular Stable Diffusion image generation model, as outlined in a paper published in December. The authors wrote that unlike previous studies, they didn’t need to train or fine-tune the AI models to create these images. The researchers—from the Graduate School of Frontier Biosciences at Osaka University—said that they first predicted a latent representation, which is a model of the image’s data, from fMRI signals. Then, the model was processed and noise was added to it through the diffusion process. Finally, the researchers decoded text representations from fMRI signals within the higher visual cortex and used them as input to produce a final constructed image.

The quest to restore Notre Dame’s sound

Looking up at the catheral’s nave, there are three holes where the spire fell.  Much of the cathedral’s restoration, projected to be completed in 2024, will address these large holes. They affect not just the structure of the building, but also something that cannot be seen: the acoustics. “Notre Dame has lost about 20 percent of its acoustics,” says Mylène Pardoen, who is the co-director of the acoustics team working on Notre Dame — under the aegis of the French Ministry of Culture and the Centre National de la Recherche Scientifique (C.N.R.S.), a research organization from whose ranks specialists have been drawn for the restoration. The holes caused a measurable decline in the glorious resonances that gave the building its unique sound.

From Max Read’s newsletter:

I counted nearly two dozen accounts and websites with similar logos, storefronts, wares, and nonsense names: In addition to Narry, Himmo, Rotu, and Tadu, there’s Zodu and Bexe, which like the four James identified also have black-and-white logos and claim to be “committed to providing unique products at tremendous values to our customers”; Zimma and Rommo have identical storefronts to the Zodu/Bexe family of shops but feature rainbow, rather than black-and-white, logos; Dula, Potta (or, according to the logo on the navigation bar at the top, “Putta”), Bezenpy, Bezenfy, and Tozdy, have Zimma/Rommo-style rainbow logos but a different storefront and a promise to “dedicate ourselves to providing the latest blanket, clothes, canvas, ornament, jewels and accessories”; finally, there’s Poxo, Gota, Duno, each of which sports a rainbow logo but claims it “curates 100 amazing fandom-related items and accessories.” All of the sites sell a narrow and largely overlapping range of products, a dollar-store mix of junky gadgets, clothes, household decoration, and ear-wax cleaners.

Here’s an essay that The Edge published by Daniel Kahneman, professor of psychology emeritus at Princeton University, author of Thinking, Fast and Slow, and the recipient of the 2002 Nobel Prize in Economic Sciences.

“To a good first approximation, people simply don’t change their minds about anything that matters. Let’s start from the main domains where we know people don’t change their minds—politics or religion. When you ask people, why do you believe what you believe? They answer by giving reasons for their beliefs. Subjectively, we experience that reasons are prior to the beliefs that can be deduced from them. But we know that the power of reasons is an illusion. The belief will not change when the reasons are defeated. The causality is reversed. People believe the reasons because they believe in the conclusion. In politics and in religion, the main driver is social. We believe what the people we love and trust believe. This is not a conscious decision to conform by hiding one’s true beliefs. It’s the truth. This is how we believe. Indeed, beliefs persevere even without any social pressure.”
