Lord Kelvin and his Atomic Vortices

by Jonathan Kujawa

One hundred and fifty years ago atoms were mysterious things. They could only be studied indirectly. We knew about their interactions with each other as a gas, the frequencies of light they prefer to absorb and emit, and various other properties. Nowadays we can capture the image of a single hydrogen atom, but back then atoms could only be understood through the shadows they cast in the macro world.

At the time two explanations were in vogue. The atomists went with the ancient Greeks and viewed atoms as small billiard balls clacking against each other as they moved through empty space. This point of view worked great for explaining the behavior of gases, but didn't help much in explaining the intrinsic properties observed by chemists. On the other hand, the followers of the theory of Boscovich, an eighteenth century Jesuit, thought that atoms were points of force which alternately repelled and attracted each other depending on how close they were. This theory held promise for explaining the electromagnetic properties of atoms, but it also had its drawbacks.

On February 18, 1867 William Thomson (aka Lord Kelvin) read out his paper “Vortex Atoms” to the assembled members of the Royal Society of Edinburgh. In it he suggested a novel alternative to these two theories.

As everyone knew at the time, the universe was permeated by the luminiferous ether. Light traveled as a wave even through “empty” space and, well, waves travel through something, so what was that something? Luminiferous ether! It was a beautiful idea, but eventually the evidence piled up against the ether. The Michaelson-Morley experiment put a stake through its heart in 1887.

But in 1867 the luminiferous ether was widely considered a standard feature of the physical world. Taking his inspiration from recent work in hydrodynamics and, presumably, a fine pipe of tobacco, Lord Kelvin realized that instead of viewing atoms and the ether as two separate things, we could instead think of atoms as vortices in the ether itself. Specifically, he thought of each atom as a knotted tubular shape:

From “On Vortex Motion” by Lord Kelvin [1]

His theory neatly explained a wide variety of atomic phenomena. The rich variety of possible knots justified the wide variety of atoms, the fact that the type of knot is unchanged under small perturbations (after all, you can't turn the knots in Lord Kelvin's table from one into another without applying real violence) explains the robust stability of atoms, and knots will clearly vibrate at different frequencies from one another and so will naturally prefer to absorb and emit light energy at differing levels. For example, Thomson thought the two linked circles in the lower left might be the sodium atom because of sodium's two spectral lines.

Tiger Dad

by Jalees Rehman

Poetry Engraved in TreeSome years ago, I was enveloped by the desire to see our children grow up to be poets. I used to talk to them about poetic metaphors, rhymes and read to them excerpts from the biographies of famous poets. When the kids were learning about haikus at school, I took the opportunity to pontificate on the controversies surrounding the 5-7-5 syllable counts and the difficulties of imposing classic Japanese schemes on the English language, which abounds in diphthongs and long syllables.

The feedback from our children was quite mixed, ranging from polite questions such as “Do you know how long this will take?” to less polite snores. I had apparently not yet succeeded in my attempts to awaken their inner poet.

Our younger son was about eight years old, when we found out about a wonderful opportunity to inculcate the love of literature into our children: The Chicago Printers Row Literature Festival! I was especially excited by the fact that they would have a special “Lil' Lit” area, just for children. I convinced the whole family to go – promising to reward each kid with $5 if they accompanied us. I hoped that my poetry monologues had prepared the children for the poetic muses that they would encounter at the festival.

Even though it was early June, Chicago was experiencing one of its rare June Gloom weekends with cloudy, drizzly weather and frosty breezes. After exiting the parking garage, our kids tried to renegotiate the promised $5 reward in light of the unpleasant weather. I brushed off their whining and charged towards the long-awaited beacon of literary pleasure.

A KINDER, GENTLER FATHERLAND

by Brooks Riley

(I began writing this article months ago, long before the refugee crisis.)

Morgen! (Morning!)

Guten Morgen! (Good morning!)

Morgen zusammen! (Morning, you two!)

Morgen Ihr zwei! (Morning, you two!)

Kalimera! (Morning, in Greek)

Servus! (Hi or bye, in leftover Latin from upper Bavaria)

Buenos Dias! (Morning, in Spanish)

Tag! (Good day, in North German)

Einen wunderschönen guten Morgen! (A beautiful good morning!)

Backhütte-3This is how my day begins. R and I sit at one of two tables in front of the wee Greek café on a shady street in the Giesing neighborhood of Munich. Like the proverbial all-weather postman, we show up every day, sit outside, smoke cigarettes, share a Zimtschnecke (a kind of cinnamon bun), drink cappuccinos, and watch the world go by—quite literally.

Giesing, with its Obergiesing and Untergiesing, is a now a melting pot of Munich—a quiet oasis of multicultural harmony. It’s always been a working-class neighborhood, not frequented by the grand, but also not ignored by the city fathers. Its 5-story balconied apartment complexes are spaciously nestled in lush green landscapes and along tree-lined streets. A vast elegant park provides meadows for dogs that need exercise and people who want a solitary walk or a picnic or a meditative sit on one of the many benches. Franz Beckenbauer, the second most famous German after Goethe, comes from Giesing, a paradise for families with limited means, born of functional, benign socialism, and a model of integration.

I’ve been sheltered all my life, isolated by acreage or a fine address. Even in New York, where I used to live, there was never a neighborhood feeling, even on the Upper West Side. New York is too big. The chances of seeing the same person on the street on consecutive days are slim. The chances of speaking to a stranger are nil. Los Angeles is worse–no one walks at all.

In Giesing, we know nearly everyone who passes by the café between 6:30 and 8 a.m. Even if they don’t stop to chat, they nod or greet us warmly. They come in all shapes, ages and backgrounds—from Africa, South America, Turkey, Asia, the Middle East, Eastern Europe, the Balkans, and Germany.

Wine and the Metaphysics of Time

by Dwight Furrow

Old wine storageWine is useless. It bakes no bread, does no work, and solves no problem. The alcohol loosens tongues and serves as social lubricant, but wine is an inefficient delivery system for alcohol—there are faster, cheaper ways of getting drunk. No one needs wine. Wine does nothing but give pleasure.

Love of wine is thus a useless passion, an arena of pure play, but therein lies its peculiar power. It joins the realm of those objects that express rather than perform–objects like old musical instruments, ancient manuscripts, childhood toys, or Grandma's jewelry. Useless but precious because of the experiences they enable.

When we are consumed by a useless passion, we become more attuned to the allusive meanings and hidden dimensions of the object of love. The object acquires an aura of mystery when unmoored from practical function and can serve as a universal talisman to which all sorts of meanings can be attached. Those moments in which we experience a useless passion and grasp the intrinsic, non-instrumental value of things are not only moments of pleasure but moments in which we glimpse a world of the imagination yet one in which matter resists conceptualization, the hard surfaces of reality resist manipulation because they have their own capacities and developmental direction, and meaning expands beyond what can be calculated or measured.

Among objects of love, wine has its own peculiar attractions. Wine, when considered aesthetically, brings traces of the sacred to our lives that are otherwise thoroughly enmeshed in practical tasks. The demand to slow down and savor opens a time and space in which we can be receptive to multiple ways of understanding the interplay between nature and culture because wine partakes of both.

Shalom and Salaam in Syria (What Some Philosophers Say)

Tammam azzam bon voyageby Leanne Ogasawara

I can't recall now where I originally found this, but several years ago I stumbled on an interesting Japanese translation for the words shalom and salaam.

1) 平和 (対国、対神、対人) ・・・和平、和解 Peace (no conflict; no fighting)

2) 平安 (個人的)・・・平穏、無事、安心、安全 Inner peace and calm; no inner trouble
3) 繁栄 (商業的) Flourishing (business)
4) 健康 (肉体的、精神的) ・・・健全、成熟 Physical health
5) 充足 (生命的) ・・・満足、生きる意欲 Satisfaction, fullness, sufficiency
6) 知恵 (学問的) ・・・悟り、霊的開眼 Enlightenment, wisdom
7) 救い (宗教的) ・・・暗闇から愛の支配へ To be saved (by Love)
8) 勝利 (究極的) ・・・罪と世に対する勝利 Triumph (over evil)

Does shalom and salaam really embody all that the Japanese translator was suggesting above? I have no idea, but the proposed translation really struck me, I felt it captured the wonderfully generous spirit of hospitality that I experienced in the Middle East.

Like the Pax in the Catholic liturgy

Pax Domini sit semper vobiscum (The peace of the Lord be with you always)

It is a sign of goodwill for the other. But it is also, I am told, a reminder that we cannot flourish in the eyes of God unless we recognize him in the people around us. This greeting dates to very early times in the Christian church and is an ancient practice informed by the hospitality codes that have such deep roots in the cultures of the Middle East (among other places).

And best of all, it is traditionally delivered with a kiss on the cheek.

++

Almost two years ago to the day, I wrote here in these pages about what I considered to be the delusional liberal response to the crisis in Syria.

It was at that time that I became utterly fascinated by Derrida and Levinas' “ethic of hospitality.”

Derrida's work on this subject is rooted firmly in the work of the Lithuanian-born French philosopher Emmanuel Levinas. But Levinas himself was responding to –who else?– Heidegger.

(All roads lead to Heidegger).

Ah, herr Heidegger–he was so brilliant and yet how could a philosophical system that great have gone that awry? Levinas, who was Jewish, had a particularly strong complaint on this count.

Where did Heidegger go wrong? It is one of the great problems of modern Continental philosophy.

Blob Justice, Part 2

by Misha Lepetic

“For the people are all in all.”
~ Herodotus III.80.

Lord-of-the-flies_aLast month I reviewed a small but representative selection of instances of Internet vigilantism. Whether we are talking about Cecil the Lion or Justine Sacco, the causes and the consequences may vary, but they share several characteristics, such as the speed with which events unfolded, and their very real-life consequences, such as ruined careers. But I elided the subtler mechanics of why these instances actually occur. Put another way, what gives rise to the mob in the first place? So, in a time-honored essayistic maneuver, I will revert to that quasi-mythical place Where All Things Began, aka ancient Greece.

The scene is ancient Persia, and our chronicler is the inimitable Herodotus. Having taken the throne in a coup, Darius debates the best form of government with the seven Persian nobles who were his co-conspirators. Considering how these things can go, it is a blessedly short discussion, with democracy, oligarchy and monarchy representing the three possibilities. The noble Otanes puts forward a lukewarm endorsement of democracy, but it's very much a straw man. He is more concerned with the shortcomings of monarchy than what might be the virtues of democracy. Another noble, Megabyzus, then speaks in support of oligarchy:

For there is nothing so void of understanding, nothing so full of wantonness, as the unwieldy rabble. It were folly not to be borne, for men, while seeking to escape the wantonness of a tyrant, to give themselves up to the wantonness of a rude unbridled mob. The tyrant, in all his doings, at least knows what is he about, but a mob is altogether devoid of knowledge; for how should there be any knowledge in a rabble, untaught, and with no natural sense of what is right and fit? It rushes wildly into state affairs with all the fury of a stream swollen in the winter, and confuses everything. Let the enemies of the Persians be ruled by democracies.

For his part, Darius acknowledges democracy and oligarchy, but it wouldn't be a spoiler to reveal that he ultimately settles on monarchy, with himself as the head of state. Thus Herodotus sets the stage for the war between the Greeks and the Persians. In a sense, the Histories can be viewed as a meandering meditation on the best form of government, whose merits are ultimately determined on the battlefield.

Toothless, Eating: On Pather Panchali (Part 1)

by Madhu Kaza

“That girl won't leave any fruit on the trees,” a woman complains looking down from the roof of her home. In the orchard below the girl runs and –once she is in the clear — skips home hiding a guava in her dress. She stashes the fruit under a bunch of bananas in a covered bowl on the veranda. Then she pours some water into a dish that she carries across the yard and places next to a large earthen vessel from which she plucks three white kittens. The opening scene of Satyajit Ray's film Pather Panchali is one of stealing and feeding, mischief and care.

Pather_panchali_04

An old woman squats over a bowl of rice on the floor of the veranda. Small clumps of the rice which she mixes and squeezes into balls have fallen on the floor. She eats with her right hand, her wrinkled left hand pressed to the floor for support. Her emaciated face is toothless and her profile dramatic –a hooked nose, sunken cheeks and a sharp, jutting chin. We know she is frail, but hunched over in her white widow's sari, the severity of her features makes her look at times, at medium distance, not unlike a vulture. She eats with absorption and licks her fingers when she is done. The girl, Durga, sits behind the old woman watching her eat. When the old woman turns around and sees Durga she says, “I forgot to save some for you.” She uncovers the fruit bowl and reaches for a banana, discovering the guava that the girl has left for her. She examines the guava closely, beaming with delight.

A French filmmaker once walked out during a screening of Pather Panchali at Cannes and proclaimed, “I don't want to see a movie of peasants eating with their hands.”

A new “culture of nature” is changing the way we live – and could change our politics, too

Robert MacFarlane in the New Statesman:

ScreenHunter_1365 Sep. 13 19.46In 1972, Gregory Bateson published Steps to an Ecology of Mind, a collection of his essays from the previous three decades. Bateson was a dazzlingly versatile thinker, whose work shaped the fields of anthropology, linguistics and cybernetics, as well as the movement we now call environmentalism. Near the end of the book, Bateson deplored the delusion of human separation from nature. “We are not,” he warned, “outside the ecology for which we plan.” His remedy for this separatism was the development of an “ecology of mind”. The steps towards such a mind were to be taken by means of literature, art, music, play, wonder and attention to nature – what he called “ecological aesthetics”.

Bateson, who died in 1980, would have been excited by what has happened in the culture of our islands over the past 15 years. An ecology of mind has emerged that is extraordinary in its energies and its diversity. In nurseries and universities, apiaries and allotments, transition towns and theatres, woodlands and festivals, charities and campaigns – and in photography, film, music, the visual and plastic arts and throughout literature – a remarkable turn has occurred towards Bateson’s ecological aesthetics. A 21st-century culture of nature has sprung up, born of anxiety and anger but passionate and progressive in its temperament, involving millions of people and spilling across forms, media and behaviours.

Let’s all go to Mars

John Lanchester in the London Review of Books:

MTI5ODczMTcyMzUzODI4ODc0Some stories are so well known in outline that we don’t really know them at all. The headline news about the Wright brothers’ invention of powered flight is so familiar that it’s easy to think we know all about it. David McCullough’s excellent biography The Wright Brothers brings the story back to life with facts that the non-specialist either doesn’t know or has blotted out with a misplaced broad brush. Yeah yeah, we get it: the brothers were provincial tinkerers who first flew their invention at Kitty Hawk, then became world-famous. It turns out, though, that there is a lot of devil in the details.

The tinkering, for instance. The Wrights were pioneers in the cycling business who ran a bicycle shop in Dayton, Ohio. Wilbur was born in 1867 and Orville in 1871. They were an unusually close pair who all their lives lived together, worked together, ate together and shared a joint bank account. (McCullough is too respectful of their boundaries to say so, but it seems likely that they were both lifelong virgins.) One of the only things they didn’t do together was fly: that would have been too much of a risk to the irreplaceable knowledge they’d jointly accumulated. Their father, Milton, was a bishop in the United Brethren Church who accepted his sons’ lack of faith with equanimity, and was going on suffragettes’ marches with his only daughter, Katherine, in his eighties. Katherine, a teacher, was the only family member to go to university, and the only sibling to have consummated a relationship, marrying at the age of 52.

‘It isn’t true,’ Wilbur later wrote, ‘to say we had no special advantages … the greatest thing in our favour was growing up in a family where there was always much encouragement to intellectual curiosity.’ Wilbur’s interest in flight began in childhood; it turned into an obsession and then into a practical plan. Other pioneers of flight were focused on the question of power. The Wrights were fascinated by birds, and learned a lot from their study of them. One of Wilbur’s crucial insights was that flying, like cycling, was a question of balance. He saw that bird flight was all about equilibrium: about the bird’s keeping itself in the air with the maximum efficiency and minimum effort.

The Earth has 50 billion tons of DNA. What happens when we have the entire biocode?

Dawn Field in Aeon:

ScreenHunter_1364 Sep. 13 17.03In case you weren’t paying attention, a lot has been happening in the science of genomics over the past few years. It is, for example, now possible to read one human genome and correct all known errors. Perhaps this sounds terrifying, but genomic science has a track-record in making science fiction reality. ‘Everything that’s alive we want to rewrite,’ boasted Austen Heinz, the CEO of Cambrian Genomics, last year.

It was only in 2010 that Craig Venter’s team in Maryland led us into the era of synthetic genomics when they created Synthia, the first living organism to have a computer for a mother. A simple bacterium, she has a genome just over half a million letters of DNA long, but the potential for scaling up is vast; synthetic yeast and worm projects are underway.

Two years after the ‘birth’ of Synthia, sequencing was so powerful that it was used to extract the genome of a newly discovered, 80,000-year-old human species, the Denisovans, from a pinky bone found in a frozen cave in Siberia. In 2015, the United Kingdom became the first country to legalise the creation of ‘three-parent babies’ – that is, babies with a biological mother, father and a second woman who donates a healthy mitochondrial genome, the energy producer found in all human cells.

William Dalrymple: One sure way for Britain to get ahead – stop airbrushing our colonial history

William Dalrymple in The Guardian:

ScreenHunter_1363 Sep. 13 16.56For better or for worse, the British empire was the most important thing the British ever did. It altered the course of history across the globe and shaped the modern world. It also led to the huge enrichment of Britain, just as, conversely, it led to the impoverishment of much of the rest of the non-European world. India and China, which until then had dominated global manufacturing, were two of the biggest losers in this story, along with hundreds of thousands of enslaved sub-Saharan Africans sent off on the middle passage to work in the plantations.

Yet much of the story of the empire is still absent from our history curriculum. My children learned the Tudors and the Nazis over and over again in history class but never came across a whiff of Indian or Caribbean history. This means that they, like most people who go through the British education system, are wholly ill equipped to judge either the good or the bad in what we did to the rest of the world.

This matters. We see British diplomats, businessmen and politicians repeatedly wrongfooted as they constantly underestimate the degree to which we are distrusted across the breadth of the globe, and in a few places actively disliked. Because of the wrong-headedly positive spin we tend to put on our imperial past, we often misjudge how others see us, and habitually overplay our hand.

Last month a video went viral in India of the eloquent Congress politician and writer Shashi Tharoor arguing at the Oxford Union that Britain owed India immense reparations for the damage inflicted by the empire: at last count the YouTube video of his speech had around 3m views.

The Redhead and the Gray Lady: How Maureen Dowd became the most dangerous columnist in America—on her own, very female terms

Ariel Levy in New York Magazine:

Redhead051021_1_175Possibly, there are even more naked women at Maureen Dowd’s house today than there were when this place was JFK’s Georgetown bachelor pad in the fifties. They are lounging in the vintage posters, carved into her Deco furniture, painted in huge trompe l’oeil pastorals on the living-room wall. “My girlfriend Michi said, ‘You’ve got to paint clothes on them,’ like you know how they did at the Sistine Chapel?” says Dowd, who is drinking white wine from a goblet with a naked woman carved into its stem. “But I like them. I think they’re kind of campy.” Michi is Michiko Kakutani, one of Dowd’s circle of extremely close female friends at the New York Times, where Dowd is, of course, the only female op-ed columnist. It’s a post she says she is “not temperamentally suited to,” despite the fact she’s been doing it for ten years and has won a Pulitzer and a passionate army of fans in the process, because Dowd doesn’t like “a lot of angst in my life,” and it is specifically her job to provoke. Her natural inclination—her fundamental drive—is, rather, to seduce. But then those two things are not entirely unrelated.

…Dowd says she’s not the “private-plane type. It makes me nervous. I mean, I don’t even like to fly first class.” But her taste for famous men has, from time to time, required it of her. She describes Michael Douglas, whom she dated right before he married Catherine Zeta-Jones, as “a really nice guy, a very romantic guy.” The humor of their romance is not lost on her: “Whether he can handle a woman who wields ice picks? I used to tease him about that. Sometimes actors ask me out, and then I’m worried because they can act like they’re not scared of me, or threatened? But then maybe later they are. I remember him announcing at dinner, like way after we knew each other: ‘I’m not scared of you.’ But it made me nervous that he had to tell me. I also became close with his father, Kirk,” says Dowd. “He told me this funny story once about when he was first discovering his Judaism and he was making The Bad and the Beautiful and he was fasting on certain days, and he looked at me and he goes, ‘Do you have any idea how hard it is to make love to Lana Turner on an empty stomach?’ ”

The Next Wave: This can’t be the end of human evolution. We have to go someplace else.

A conversation with John Markoff in Edge:

Markoff640I'm in an interesting place in my career, and it's an interesting time in Silicon Valley. I grew up in Silicon Valley, but it's something I've been reporting about since 1977, which is this Moore's Law acceleration. Over the last five years, another layer has been added to the Moore's Law discussion, with Kurzweil and people like him arguing that we're on the brink of self-aware machines. Just recently, Gates and Musk and Hawking have all been saying that this is an existential threat to humankind. I simply don't see it. If you begin to pick it apart, their argument and the fundamental argument of Silicon Valley, it's all about this exponential acceleration that comes out of the semiconductor industry. I suddenly discovered it was over. Now, it may not be over forever, but it's clearly paused. All the things that have been driving everything that I do, the kinds of technology that have emerged out of here that have changed the world, have ridden on the fact that the cost of computing doesn't just fall, it falls at an accelerating rate. And guess what? In the last two years, the price of each transistor has stopped falling. That's a profound moment.

…Ubiquitous computing, or the Internet of things, is all supposed to disappear. The problem is, is it going to disappear into us? What could possibly go wrong? There is an argument that these machines are going to replace us, but I only think that's relevant to you or me in the sense that it doesn't matter if it doesn't happen in our lifetime. The Kurzweil crowd argues this is happening faster and faster, and things are just running amok. In fact, things are slowing down. In 2045, it's going to look more like it looks today than you think.

Sunday Poem

Boy with a Halo at the Farmers Market
.

The metal halo was bolted into his skull,
little drills secured the scaffold,
so his bones could rebuild themselves.
How truly graced he must have been
to survive a broken neck. Someday
he’ll remember how he had to turn
his whole body, caged, to watch
the fruit vendor polish apples. His hair
will cover the evenly spaced scars.
He’ll go to school for architecture,
having learned to appreciate girders.
He’ll come to love the gold leaf halos
of medieval art, the flash of The Savior
in cracked oils. He may carry himself
a little gingerly, he may never ride a horse
again, but he’ll kiss his wife’s neck
in a dark theater, taking leisure, blessing
each vertebra, one lucky break at a time.

What we write about when we write about celebrities

Kathleen Rooney at The Poetry Foundation:

Kanye-WestA glance at celebrity websites and magazines serves to confirm that it is possible to make a living by taking photos of very famous people doing very ordinary things: walking dogs, pumping gas, dropping children off at daycare. It might be difficult to identify the precise desire that these images are intended to stoke or satisfy—the thrill of peeking through the regimented scrim of celebrity to glimpse something genuine, maybe, or simply the reassurance that despite their exalted state, these stars’ quotidian concerns are not wholly different from our own. But the rush is clearly widespread, if not universal.

This spring, Wesleyan University Press released Sarah Blake’s debut poetry collection,Mr. West, which achieves its momentum from examining the distant spectacle of celebrities alongside the enduring curiosity about what they might really be like as human beings. This “unauthorized lyric biography,” as Blake calls it, juxtaposes Kanye West’s life as a black male celebrity with Blake’s own as a white female artist and soon-to-be-mother. “You miss her and I miss him but // surely I cannot say if, when you think of death, you, Kanye, think of the / heart,” she writes in “Kanye’s Circulatory System,” writing of the death of her grandfather and of West’s loss of his mother, Donda. By putting their lives in conversation, she provokes her readers to wonder:What are we able to know about superstars, as far as we are from their fabulous orbits? What are we ever able to know definitively about the experience of someone else? Her answer: people have a great deal to learn from their experience of celebrities, particularly the feeling—familiar to all who have ever considered themselves fans—of identifying with a person whom one has likely never seen in person.

Mr. West builds the enigma and inaccessibility of celebrities—and the way their images are mediated—into the text. Presumably for permissions reasons, Blake can’t quote extensively from West’s lyrics. Thus, she replaces quotations with blacked-out bars and attributions so that readers can find them for themselves.
