Particle Physicists Puzzle Over a New Duality

Katie McCormick in Quanta:

Last year, the particle physicist Lance Dixon was preparing a lecture when he noticed a striking similarity between two formulas that he planned to include in his slides.

The formulas, called scattering amplitudes, give the probabilities of possible outcomes of particle collisions. One of the scattering amplitudes represented the probability of two gluon particles colliding and producing four gluons; the other gave the probability of two gluons colliding to produce a gluon and a Higgs particle.

“I was getting a little confused because they looked kind of similar,” said Dixon, who is a professor at Stanford University, “and then I realized that the numbers were basically the same — it’s just that the [order] had gotten reversed.”

He shared his observation with his collaborators over Zoom. Knowing of no reason the two scattering amplitudes should correspond, the group thought perhaps it was a coincidence.

Why reducing the risk of nuclear war should be a key concern of our generation

Max Roser at Our World in Data:

Cities that are attacked by nuclear missiles burn at such an intensity that they create their own wind system, a firestorm: hot air above the burning city ascends and is replaced by air that rushes in from all directions. The storm-force winds fan the flames and create immense heat.

From this firestorm large columns of smoke and soot rise up above the burning cities and travel all the way up to the stratosphere. There it spreads around the planet and blocks the sun’s light. At that great height – far above the clouds – it cannot be rained out, meaning that it will remain there for years, darkening the sky and thereby drying and chilling the planet.

Salman Rushdie’s entire life has been an act of defiance

Suzanne Nossel in The Guardian:

The attack on Rushdie is a wake-up call for all of us who have a stake in free expression, which is all of us, period. While we do not yet know the motives of his attackers, it is hard to envisage a scenario in which this brazen, premeditated attack, the first in memory targeting a writer at a literary event in the United States, had nothing to do with Rushdie’s words and ideas.

The shocking attack on Rushdie comes at a time of intensifying and protean attacks on free expression worldwide. PEN America’s annual Freedom to Write Index tracks the cases of individual writers in prison worldwide. Our research has documented a significant jump in the number of writers, academics, and public intellectuals detained globally over the last few years. Authoritarian governments throwing writers in jail is one potent form of repression of free expression, silencing those targeted and casting a chill over all others who might dare broach controversial topics or buck orthodoxies.

Salman Rushdie and the Power of Words

Adam Gopnik in The New Yorker:

The terrorist assault on Salman Rushdie on Friday morning, in western New York, was triply horrific to contemplate. First in its sheer brutality and cruelty, on a seventy-five-year-old man, unprotected and about to speak—doubtless cheerfully and eloquently, as he always did—repeatedly in the stomach and neck and face. Indeed, we accept the abstraction of those words—“assaulted” and “attacked”—too casually. To try to feel the victim’s feelings—first shock, then unimaginable pain, then the panicked sense of life bleeding away—to engage in the most moderate empathy with the author is to be oneself scarred. (At the time of writing, Rushdie is reportedly on a ventilator, with an uncertain future, the only certainty being that, if he lives, he will be maimed for life.)

Second, it was horrific in the madness of its meaning and a reminder of the power of religious fanaticism to move people. Authorities did not immediately release a motive for the attack, but the dark apprehension is that the terrorist who assaulted Rushdie was a radicalized Islamic militant of American upbringing—like John Updike’s imaginary terrorist in the novel “Terrorist,” apparently one raised in New Jersey—who was executing a fatwa first decreed by Ayatollah Khomeini, in 1989, upon the publication of Rushdie’s novel “The Satanic Verses.” The evil absurdity of the death sentence pronounced on Rushdie for having written a book actually more exploratory than sacrilegious—in no sense an anti-Muslim invective, but a kind of magical-realist meditation on themes from the Quran—was always obvious. (Of course, Rushdie should have been equally invulnerable to persecution had he written an actual anti-Muslim—or an anti-Christian—diatribe, but, as it happens, he hadn’t.)

The delights of mischief

Alex Moran in aeon:

Now let it work, mischief, thou art afoot.
Take thou what course thou wilt!
— from William Shakespeare’s Julius Caesar (Act III, Scene II)

One of the stranger sights on the University College London campus is the clothed skeleton of the utilitarian philosopher Jeremy Bentham. Stranger still is that a waxwork head sits on its shoulders, where Bentham’s own head should be, as per his will. Meanwhile, his preserved head is elsewhere – his friends thought it looked too grotesque for display, and commissioned the waxwork one instead. Legend has it that Bentham’s real head was stolen by some students from King’s College London as a prank against their University College rivals, and a ransom demanded for returning it. Apparently, this was eventually paid up, and the head was returned.

Apocryphal or not, such tales of mischief are amusing, and apt to elicit in us a certain kind of sympathy. But there is something curious about this. Mischief is essentially a form of misbehaviour, and its practitioners are generally met with punishment and reproach rather than praise, at least when they are caught. Why is it, then, that tales of mischief so often elicit in us such a positive response? Could it be that there is something virtuous about mischief, and something noble about mischievous people, considered as a type?

Hopelessness?

Branko Milanovic over at his substack Global Inequality and More 3.0:

That today’s world situation is the worst since the end of the Second World War is not an excessive, nor original, statement. As we teeter on the brink of a nuclear war, it does not require too  many words to convince people that this is so.

The question is: how did we get here? And is there a way out?

To understand how we got here, we need to go to the end of the Cold War. That war, like the World War I, ended with the two sides understanding the end differently: the West understood the end of the Cold War as its comprehensive victory over Russia; Russia understood it as the end of the ideological competition between capitalism and communism: Russia jettisoned communism, and hence it was to be just another power alongside other capitalist powers.

The origin of today’s conflict lies in that misunderstanding. Many books have already been written about it, and more will be. But this is not all. The Euro-American world took a bad turn in the 1990s because both the (former) West and the (former) East took a bad turn. The West rejected social-democracy with its conciliatory attitude domestically and willingness to envisage a world without adversarial military blocs internationally for neoliberalism at home and militant expansion abroad. The (former) East embraced privatization and deregulation in economics, and an exclusivist nationalism in the national ideologies underlying the newly-independent states.

These extreme ideologies, East and West, were the very opposite of what people of goodwill hoped for.

Anti-Liberal

Terry Eagleton in Sidecar [h/t: Leonard Benardo]:

A well-known member of the British left once discovered to his surprise that several of his socialist friends, including myself, had all attended the same school. We weren’t, however, public schoolboys in flight from our privileged backgrounds; nor was the school the kind of place where you call the teachers Nick and Maggie and are encouraged to have sex on the floor of the assembly hall. It was a Roman Catholic grammar school in Manchester, run by an obscure order of clerics, and like most Catholic schools in Britain its pupils were almost all descendants of Irish working-class immigrants.

There have been a number of prominent Catholics on the British left, most of them what the church would call ‘lapsed’. To be lapsed is less a matter of ceasing to be a Catholic than a particular way of being one – a fairly honorific way, in fact, which includes such luminaries as Graham Greene and Seamus Heaney. The result is that nobody can ever leave the Catholic church; instead, they are simply shuttled from one category to another, rather as a retired Brigadier is still a Brigadier. The political philosopher Raymond Geuss confesses in his latest book, Not Thinking like a Liberal, that his religious upbringing failed to make him even a bad Catholic; yet bad Catholics are what the lapsed really are, often productively so. They can be heretics in the truth, to use John Milton’s phrase. Geuss may not go along with the church on such minor matters as the existence of God, but he insists that none of his fundamental attitudes have changes since his schooldays, which the clerics who taught him would no doubt be delighted to hear. As a staunch anti-liberal, he remains a bad Catholic to the end.

Humans Know a Lot, This Author Concedes, and Most of It Is Useless

Jennifer Szalai in The New York Times:

Gregg studies animal behavior and is an expert in dolphin communication. He shows how human cognition is extraordinarily complex, allowing us to paint pictures and write symphonies. We can share ideas with one another so that we don’t have to rely only on gut instinct or direct experience in order to learn. But this compulsion to learn can be superfluous, he says. We accumulate what the philosopher Ruth Garrett Millikan calls “dead facts” — knowledge about the world that is useless for daily living, like the distance to the moon, or what happened in the latest episode of “Succession.” Our collections of dead facts, Gregg writes, “help us to imagine an infinite number of solutions to whatever problems we encounter — for good or ill.”

“If Nietzsche Were a Narwhal” is mostly fixated on the ill, or the way that humans insist they are improving things when they are ultimately mucking them up. There is already a stuffed shelf of books about how we aren’t as smart as we like to think we are, or how our smartness can lead us astray: David Robson’s “The Intelligence Trap,” Leonard Mlodinow’s “Emotional,” books in behavioral economics by Daniel Kahneman or Dan Ariely. But Gregg makes a bigger case about how human intelligence has deformed the planet as well. He explicitly ventures into the conflict between optimists like Steven Pinker and pessimists like the British philosopher John Gray.

Republicans went crazy over the Trump search. Now they look idiotic

Max Boot in The Washington Post:

The more we learn about the FBI’s search of Mar-a-Lago, the sillier — and more sinister — the overcaffeinated Republican defenses of former president Donald Trump look. A genius-level spinmeister, Trump set the tone with a Monday evening statement announcing: “These are dark times for our Nation, as my beautiful home, Mar-A-Lago in Palm Beach, Florida, is currently under siege, raided, and occupied by a large group of FBI agents. Nothing like this has ever happened to a President of the United States before.” That description allowed his followers to imagine a scene straight out of a Hollywood action picture, with agents in FBI jackets busting down the doors and holding the former president and first lady at gunpoint while they ransacked the premises. Although Trump’s team had a copy of the search warrant, he gave no hint of why the FBI might have been there, claiming, “It is … an attack by Radical Left Democrats who desperately don’t want me to run for President in 2024.”

His followers — which means pretty much the whole of the Republican Party — took up the cry based on no more information than that. Fox News host Mark Levin called the search “the worst attack on this republic in modern history, period.” Sen. Ted Cruz (R-Tex.) called it “corrupt & an abuse of power.” Sen. Rick Scott (R-Fla.) compared the FBI to “the Gestapo.” Not to be outdone, former House speaker Newt Gingrich (R-Whackadoodle) said the FBI was the “American Stasi,” and compared its agents to wolves “who want to eat you.” “Today is war,” declared Steven Crowder, a podcaster with a YouTube audience of 5.6 million people. Rep. Marjorie Taylor Greene (R-Ga.) tweeted “DEFUND THE FBI!” Former Trump aide Stephen K. Bannon, among many others, suggested that the FBI and the Justice Department (“essentially lawless criminal organizations”) might have planted evidence.

…The New York Times, meanwhile, reported that the search was conducted by FBI agents “intentionally not wearing the blue wind breakers emblazoned with the agency’s logo usually worn during searches.” The club was closed, and Trump was not there. He was in New York, where he would plead the Fifth Amendment against self-incrimination more than 400 times during a deposition with the New York attorney general. But according to Trump’s lawyer, Trump and his family were able to watch the entire search on Mar-a-Lago’s closed-circuit security cameras. So much for the crackpot claim that the FBI could have planted evidence!

Saturday Poem

Always We Begin Again

Today you could wake up and say, It doesn’t have to be complicated
life, that is, in the way a forest overtakes the scourge of the machine.

Eventually, the scar will be covered first by high grasses and flowering
weeds, then shoulder high pines that spine their way to the leaf ceiling.

Life, you could say, could be like that. A regrowth, something
the whole forest seems to agree upon, beginning the moment after

the metal teeth carve a wound. Life could be like that, and love.
Love—the way years from now you will look down the path

the machine took and never know that once this was the way
the humans went, blistering their way, metal teeth dripping sap.

‘We Could Have Been Friends, My Father and I’ by Raja Shehadeh

Ian Black at The Guardian:

Raja Shehadeh, the well-known Palestinian author, was born in 1951 in the West Bank town of Ramallah (under Jordanian rule), three years after Israel was founded. His father, Aziz, was born in Bethlehem in 1912 (then part of the Ottoman empire), five years before the Balfour declaration paved the way for the success of the Zionist movement and the Nakba – the Palestinian catastrophe caused by the creation of the Jewish state.

Dates, birthplaces and governments matter a lot in this story. It is about the strained relationship between a father and his son, told by the son, against the background of one of the most intractable and divisive conflicts on earth. They were both intelligent and successful lawyers, so the account and the documentation are impressively comprehensive.

RETAIL GANGSTER: The Insane, Real-Life Story of Crazy Eddie

Alexandra Jacobs at the NYT:

The most famous TV ad in the Orwellian year of 1984, carefully themed to the novel named for this year, was for the Apple Macintosh desktop computer. The most infamous were those for Crazy Eddie, a chain of discount electronics stores in the New York metropolitan area.

Gesticulating wildly in a variety of costumes or just a gray turtleneck and a dark blazer, the actor Jerry Carroll, often mistaken for the mysterious Eddie, would rattle off a sales pitch ending with the vibrating, bug-eyed assurance: “His prices are INSANE!”

People hated those commercials, the journalist Gary Weiss reminds us in “Retail Gangster,” a compact and appealing account of Crazy Eddie’s artificially inflated rise and slow-mo collapse. But they worked — the company went public, with the inauspicious stock symbol CRZY — and also worked their way into punch lines of popular culture.

From Rushdie’s friend: “Always support free speech, especially speech we hate. Otherwise there’s no hope at all.”

Note: Salman is a closer friend of my sister Azra, but I know I also speak for her when I say that we are devastated by the terrible news we have received this evening and hope for his speedy and complete recovery.

Cynthia Haven in The Book Haven:

For most of us, Salman Rushdie is only a name in the news, a man famous for his books and his marriages. To some of my friends, including Abbas Raza, founder of 3QuarksDaily (we’ve written about it here), he is more than that. He is a personal friend, and a friend of his extended Pakistani family.

Hence, Karachi-born Abbas Raza wrote on Facebook today, after the attempted murder of Rushdie: “He is in critical condition with much blood loss. Apparently an artery in his neck was severed. I hope he comes back from this roaring. Let us all, in this dangerous moment, renew our commitment to always supporting free speech, especially speech we hate. Otherwise there’s no hope at all.”

The Case for Shorttermism

Robert Wright in Nonzero Newsletter:

Effective altruism—EA for short—is a pretty straightforward extension of utilitarian moral philosophy and drew much of its founding inspiration from the most famous living utilitarian philosopher, Peter Singer. The basic idea is that you should maximize the amount of increased human welfare per dollar of philanthropic donation or per hour of charitable work. A classic EA expenditure is on mosquito nets: You can actually count the lives you’re theoretically saving from the ravages of malaria and compare that with the number of lives you could have saved by, say, funding a water purification project.

Longtermism, by adding all generations yet unborn to the utilitarian calculus, vastly expands the horizons of effective altruists. Instead of just scanning Earth in search of people who can be efficiently helped, they can scan eternity. That may sound like a nebulous enterprise, but it has at least one clear effect that I applaud: It can get effective altruists focused on the problem of “existential threats”—things that could conceivably wipe out the whole human species.

Of Craft and Matter

Antonio Muñoz Molina at Hudson Review:

The foreground of the most looked-at painting in the museum is partly taken up by a painting seen from the back. Everything in Las Meninas seems overt and at the same time is deceptive. The mystery of what may or may not be painted on the canvas is counterpoised by the concrete evidence of its reverse, and along with it, by the irreducible material nature of the art of painting, emphasized by the scale of that enormous object made of stiff, rough cloth and wooden bars locked together firmly enough for the contraption to stand upright. Velázquez devotes as much attention to those carefully cut pieces of wood—their knots, their volume, the way the light shows them in relief, the rough texture of the cloth—as to the blond, dazzled hair of the infanta or to the butterfly, perhaps of silver filigree, that the maid María Agustina Sarmiento wears in her hair, as distinct as a piece of jewelry when seen from a distance, though it dissolves into small abstract patches of color when seen up close. Velázquez had “brushes . . . furnished with long handles,” says Palomino, “which he employed sometimes to paint from a greater distance and more boldly, so it all seemed meaningless from up close, and proved a miracle from afar.”
