All the Trump Indictments Everywhere All at Once - 0 views

  • Here’s Furman:There’s what economists think people should think about inflation—and what people actually think about inflation are different. . . .Inflation has big winners and losers. So surprise inflation helps debtors and hurts creditors. And there are probably tens of millions of people in our economy who have benefited from inflation. Maybe it’s a business that was able to raise prices more. Maybe a worker who was able to get a bigger raise. Maybe it’s someone whose mortgage is now worth 10 percent less.But there are not tens of millions of people who think they’ve benefited from inflation. In fact, I’m not sure there are tens of people who think they’ve benefited from inflation.And so it has these winners and losers. The losers are very aware of their losses. The winners are completely oblivious to their gains.So then as a policymaker, do you want to sort of make people happy? Or do you want to sort of do what you think is in their economic and financial interests? And that to me is not obvious.
  • Oh it’s obvious to me. The People are the problem.But they’re a persistent problem and until the AIs replace us, The People aren’t going away. So given this constraint, I’m not sure that an optimal solution is ever going to be politically possible in American democracy. The country is too fractured. Our political institutions too compromised.
  • so if you work from the assumption that we’re going to shoot wide of the mark in one direction or the other, I’d still rather be on the Trump-Biden side of having done too much, and dealing with our attendant problems than the Bush-Obama side of having done too little.

Elusive 'Einstein' Solves a Longstanding Math Problem - The New York Times - 0 views

  • after a decade of failed attempts, David Smith, a self-described shape hobbyist of Bridlington in East Yorkshire, England, suspected that he might have finally solved an open problem in the mathematics of tiling: That is, he thought he might have discovered an “einstein.”
  • In less poetic terms, an einstein is an “aperiodic monotile,” a shape that tiles a plane, or an infinite two-dimensional flat surface, but only in a nonrepeating pattern. (The term “einstein” comes from the German “ein stein,” or “one stone” — more loosely, “one tile” or “one shape.”)
  • Your typical wallpaper or tiled floor is part of an infinite pattern that repeats periodically; when shifted, or “translated,” the pattern can be exactly superimposed on itself
  • ...18 more annotations...
  • An aperiodic tiling displays no such “translational symmetry,” and mathematicians have long sought a single shape that could tile the plane in such a fashion. This is known as the einstein problem.
  • black and white squares also can make weird nonperiodic patterns, in addition to the familiar, periodic checkerboard pattern. “It’s really pretty trivial to be able to make weird and interesting patterns,” he said. The magic of the two Penrose tiles is that they make only nonperiodic patterns — that’s all they can do.“But then the Holy Grail was, could you do with one — one tile?” Dr. Goodman-Strauss said.
  • now a new paper — by Mr. Smith and three co-authors with mathematical and computational expertise — proves Mr. Smith’s discovery true. The researchers called their einstein “the hat,
  • “The most significant aspect for me is that the tiling does not clearly fall into any of the familiar classes of structures that we understand.”
  • “I’m always messing about and experimenting with shapes,” said Mr. Smith, 64, who worked as a printing technician, among other jobs, and retired early. Although he enjoyed math in high school, he didn’t excel at it, he said. But he has long been “obsessively intrigued” by the einstein problem.
  • Sir Roger found the proofs “very complicated.” Nonetheless, he was “extremely intrigued” by the einstein, he said: “It’s a really good shape, strikingly simple.”
  • The simplicity came honestly. Mr. Smith’s investigations were mostly by hand; one of his co-authors described him as an “imaginative tinkerer.”
  • When in November he found a tile that seemed to fill the plane without a repeating pattern, he emailed Craig Kaplan, a co-author and a computer scientist at the University of Waterloo.
  • “It was clear that something unusual was happening with this shape,” Dr. Kaplan said. Taking a computational approach that built on previous research, his algorithm generated larger and larger swaths of hat tiles. “There didn’t seem to be any limit to how large a blob of tiles the software could construct,”
  • The first step, Dr. Kaplan said, was to “define a set of four ‘metatiles,’ simple shapes that stand in for small groupings of one, two, or four hats.” The metatiles assemble into four larger shapes that behave similarly. This assembly, from metatiles to supertiles to supersupertiles, ad infinitum, covered “larger and larger mathematical ‘floors’ with copies of the hat,” Dr. Kaplan said. “We then show that this sort of hierarchical assembly is essentially the only way to tile the plane with hats, which turns out to be enough to show that it can never tile periodically.”
  • some might wonder whether this is a two-tile, not one-tile, set of aperiodic monotiles.
  • Dr. Goodman-Strauss had raised this subtlety on a tiling listserv: “Is there one hat or two?” The consensus was that a monotile counts as such even using its reflection. That leaves an open question, Dr. Berger said: Is there an einstein that will do the job without reflection?
  • “the hat” was not a new geometric invention. It is a polykite — it consists of eight kites. (Take a hexagon and draw three lines, connecting the center of each side to the center of its opposite side; the six shapes that result are kites.)
  • “It’s likely that others have contemplated this hat shape in the past, just not in a context where they proceeded to investigate its tiling properties,” Dr. Kaplan said. “I like to think that it was hiding in plain sight.”
  • Incredibly, Mr. Smith later found a second einstein. He called it “the turtle” — a polykite made of not eight kites but 10. It was “uncanny,” Dr. Kaplan said. He recalled feeling panicked; he was already “neck deep in the hat.”
  • Dr. Myers, who had done similar computations, promptly discovered a profound connection between the hat and the turtle. And he discerned that, in fact, there was an entire family of related einsteins — a continuous, uncountable infinity of shapes that morph one to the next.
  • this einstein family motivated the second proof, which offers a new tool for proving aperiodicity. The math seemed “too good to be true,” Dr. Myers said in an email. “I wasn’t expecting such a different approach to proving aperiodicity — but everything seemed to hold together as I wrote up the details.”
  • Mr. Smith was amazed to see the research paper come together. “I was no help, to be honest.” He appreciated the illustrations, he said: “I’m more of a pictures person.”

What Can We Learn from Barnes & Noble's Surprising Turnaround? - 0 views

  • This is James Daunt’s super power: He loves books.
  • Daunt used the pandemic as an opportunity to “weed out the rubbish” in the stores. He asked employees in the outlets to take every book off the shelf, and re-evaluate whether it should stay. Every section of the store needed to be refreshed and made appealing.
  • Daunt also refused to dumb-down the store offerings. The key challenge, he claimed was to “create an environment that’s intellectually satisfying—and not in a snobbish way, but in the sense of feeding your mind.”
  • ...4 more annotations...
  • That’s an extraordinary thing to hear from a corporate CEO. Daunt wanted to run a bookstore that was “intellectually satisfying” and “feeds your mind.
  • If you want to sell music, you must love those songs. If you want to succeed in journalism, you must love those newspapers. If you want to succeed in movies, you must love the cinema.
  • You don’t fall in love for logical reasons, and you could never convince someone else to do so on the basis of arguments. People either feel it or they don’t. That’s true whether you love your spouse or you love something more intangible like a song or a book or a movie.
  • But even if you can’t teach this kind of love, you know it when you see it. There are people who are passionate about these things. They believe in them with ardor and devotion. You can find them and hire these people—and those are the individuals you can trust.

By the Book: Charles Frazier Wants You to Wait Before Reading the Classics - The New Yo... - 0 views

  • Disappointing, overrated, just not good: What book did you feel as if you were supposed to like, and didn’t? Do you remember the last book you put down without finishing?
  • If I’m really not enjoying a book, I bog down after 50 pages or so and stop. In those cases, I try to remind myself that not every book was written specifically for my tastes and that it’s best not to confuse my own preferences with gospel truth. I also find it useful to recognize that the writer may have spent years writing the book and knows it better — or at least deeper — than I do, so maybe the fault or flaw resides partially or completely in me.

Opinion | Empathy Is Exhausting. There Is a Better Way. - The New York Times - 0 views

  • “What can I even do?”Many people are feeling similarly defeated, and many others are outraged by the political inaction that ensues. A Muslim colleague of mine said she was appalled to see so much indifference to the atrocities and innocent lives lost in Gaza and Israel. How could anyone just go on as if nothing had happened?
  • inaction isn’t always caused by apathy. It can also be the product of empathy. More specifically, it can be the result of what psychologists call empathic distress: hurting for others while feeling unable to help.
  • I felt it intensely this fall, as violence escalated abroad and anger echoed across the United States. Helpless as a teacher, unsure of how to protect my students from hostility and hate. Useless as a psychologist and writer, finding words too empty to offer any hope. Powerless as a parent, searching for ways to reassure my kids that the world is a safe place and most people are good. Soon I found myself avoiding the news altogether and changing the subject when war came up

  • Understanding how empathy can immobilize us like that is a critical step for helping others — and ourselves.
  • Early researchers labeled it compassion fatigue and described it as the cost of caring.
  • Having concluded that nothing they do will make a difference, they start to become indifferent.
  • The symptoms of empathic distress were originally diagnosed in health care, with nurses and doctors who appeared to become insensitive to the pain of their patients.
  • Empathic distress explains why many people have checked out in the wake of these tragedies
  • when two neuroscientists, Olga Klimecki and Tania Singer, reviewed the evidence, they discovered that “compassion fatigue” is a misnomer. Caring itself is not costly. What drains people is not merely witnessing others’ pain but feeling incapable of alleviating it.
  • In times of sustained anguish, empathy is a recipe for more distress, and in some cases even depression. What we need instead is compassion.
  • empathy and compassion aren’t the same. Empathy absorbs others’ emotions as your own: “I’m hurting for you.”
  • Compassion focuses your action on their emotions: “I see that you’re hurting, and I’m here for you.”
  • “Empathy is biased,” the psychologist Paul Bloom writes. It’s something we usually reserve for our own group, and in that sense, it can even be “a powerful force for war and atrocity.”
  • Dr. Singer and their colleagues trained people to empathize by trying to feel other people’s pain. When the participants saw someone suffering, it activated a neural network that would light up if they themselves were in pain. It hurt. And when people can’t help, they escape the pain by withdrawing.
  • To combat this, the Klimecki and Singer team taught their participants to respond with compassion rather than empathy — focusing not on sharing others’ pain but on noticing their feelings and offering comfort.
  • A different neural network lit up, one associated with affiliation and social connection. This is why a growing body of evidence suggests that compassion is healthier for you and kinder to others than empathy:
  • When you see others in pain, instead of causing you to get overloaded and retreat, compassion motivates you to reach out and help
  • The most basic form of compassion is not assuaging distress but acknowledging it.
  • in my research, I’ve found that being helpful has a secondary benefit: It’s an antidote to feeling helpless.
  • To figure out who needs your support after something terrible happens, the psychologist Susan Silk suggests picturing a dart board, with the people closest to the trauma in the bull’s-eye and those more peripherally affected in the outer rings.
  • Once you’ve figured out where you belong on the dart board, look for support from people outside your ring, and offer it to people closer to the center.
  • Even if people aren’t personally in the line of fire, attacks targeting members of a specific group can shatter a whole population’s sense of security.
  • If you notice that people in your life seem disengaged around an issue that matters to you, it’s worth considering whose pain they might be carrying.
  • Instead of demanding that they do more, it may be time to show them compassion — and help them find compassion for themselves, too.
  • Your small gesture of kindness won’t end the crisis in the Middle East, but it can help someone else. And that can give you the strength to help more.

A Marketplace of Girl Influencers Managed by Moms and Stalked by Men - The New York Times - 0 views

  • Thousands of accounts examined by The Times offer disturbing insights into how social media is reshaping childhood, especially for girls, with direct parental encouragement and involvement.
  • Some parents are the driving force behind the sale of photos, exclusive chat sessions and even the girls’ worn leotards and cheer outfits to mostly unknown followers. The most devoted customers spend thousands of dollars nurturing the underage relationships.
  • The large audiences boosted by men can benefit the families, The Times found. The bigger followings look impressive to brands and bolster chances of getting discounts, products and other financial incentives, and the accounts themselves are rewarded by Instagram’s algorithm with greater visibility on the platform, which in turn attracts more followers.
  • ...8 more annotations...
  • One calculation performed by an audience demographics firm found 32 million connections to male followers among the 5,000 accounts examined by The Times.
  • Interacting with the men opens the door to abuse. Some flatter, bully and blackmail girls and their parents to get racier and racier images. The Times monitored separate exchanges on Telegram, the messaging app, where men openly fantasize about sexually abusing the children they follow on Instagram and extol the platform for making the images so readily available.
  • The so-called creator economy surpasses $250 billion worldwide, according to Goldman Sachs, with U.S. brands spending more than $5 billion a year on influencers.
  • The troubling interactions on Instagram come as social media companies increasingly dominate the cultural landscape and the internet is seen as a career path of its own.
  • Nearly one in three preteens lists influencing as a career goal, and 11 percent of those born in Generation Z, between 1997 and 2012, describe themselves as influencers.
  • “It’s like a candy store
  • Health and technology experts have recently cautioned that social media presents a “profound risk of harm” for girls. Constant comparisons to their peers and face-altering filters are driving negative feelings of self-worth and promoting objectification of their bodies, researchers found.
  • he pursuit of online fame, particularly through Instagram, has supercharged the often toxic phenomenon, The Times found, encouraging parents to commodify their children’s images. Some of the child influencers earn six-figure incomes, according to interviews.

Opinion | Black English Doesn't Have to Be Just for Black People - The New York Times - 0 views

  • , the question is why a white guy like Rife is doing that, instead of switching into a more vanilla version of colloquial white English.
  • Black English, for him, as for so many Black people, is a comfort zone, where it all gets real.
  • It was peculiar for a white person to process Black English that way, to the point of making personal use of it, until roughly the late 1990s. But things have changed.
  • ...7 more annotations...
  • It is reasonable to imagine that Rife thinks his audience processes his Black English usage as a warm method of interpersonal bonding in the same way he seems to. In fact, a tweet of his suggests that he hadn’t even been conscious of what he was doing until apprised, and doesn’t even think of himself as shifting into something “Black” at all.
  • Rife is not posing or ridiculing; he’s connecting. Linguists call it accommodation. A non-Black speaker these days may do it with a Black audience.
  • reflecting in language exactly what we were supposed to be going for: interracial harmony.
  • Except that these days, that ideal may seem a tad 1.0. Under the new identitarian mind-set, where we cherish coming together less than we cherish a diversity of identities, many see someone like Rife as culturally appropriating Black speech, something that isn’t his. “Mimesis is a kind of negation,”
  • There is simply no way that whiteness and Blackness will mingle as they have in music, cuisine, gesture, greeting styles, dating, matrimony and multiracial identity, and yet for some reason be halted at language.
  • The horse has been out of the barn ever since white kids embraced Jay-Z and Tupac.
  • style-shifting is humans’ linguistic default, not a pose or party trick.

  • Peter Higgs, the Nobel prize-winning physicist who discovered a new particle known as the Higgs boson, has died.Higgs, 94, who was awarded the Nobel prize for physics in 2013 for his work in 1964 showing how the boson helped bind the universe together by giving particles their mass
  • “A giant of particle physics has left us,” Ellis told the Guardian. “Without his theory, atoms could not exist and radioactivity would be a force as strong as electricity and magnetism.
  • “His prediction of the existence of the particle that bears his name was a deep insight, and its discovery at Cern in 2012 was a crowning moment that confirmed his understanding of the way the Universe works.”
  • ...2 more annotations...
  • The particle that carries his name is perhaps the single most stunning example of how seemingly abstract mathematical ideas can make predictions which turn out to have huge physical consequences.”
  • The Royal Swedish Academy of Sciences, which awards the Nobel, said at the time the standard model of physics which underpins the scientific understanding of the universe “rests on the existence of a special kind of particle: the Higgs particle. This particle originates from an invisible field that fills up all space.“Even when the universe seems empty this field is there. Without it, we would not exist, because it is from contact with the field that particles acquire mass. The theory proposed by Englert and Higgs describes this process.”
