The human hand in climate change

Kerry Emanuel in the Boston Review:

Two strands of environmental philosophy run through the course of human history. The first holds that the natural state of the universe is one of infinite stability, with an unchanging earth anchoring the predictable revolutions of the sun, moon, and stars. Every scientific revolution that challenged this notion, from Copernicus’ heliocentricity to Hubble’s expanding universe, from Wegener’s continental drift to Heisenberg’s uncertainty and Lorenz’s macroscopic chaos, met with fierce resistance from religious, political, and even scientific hegemonies.

The second strand also sees the natural state of the universe as a stable one but holds that it has become destabilized through human actions. The great floods are usually portrayed in religious traditions as attempts by a god or gods to cleanse the earth of human corruption. Deviations from cosmic predictability, such as meteors and comets, were more often viewed as omens than as natural phenomena. In Greek mythology, the scorching heat of Africa and the burnt skin of its inhabitants were attributed to Phaeton, an offspring of the sun god Helios, who, having lost a wager to his son, was obliged to allow him to drive the sun chariot across the sky. In this primal environmental catastrophe, Phaeton lost control and fried the earth, killing himself in the process.

These two fundamental ideas have permeated many cultures through much of history. They strongly influence views of climate change to the present day.

On what is German about German literature

Navid Kermani in Sign and Sight:

I would like to answer the question of what is German about German literature by speaking about an exemplary German writer. For me, this means not Goethe or Schiller, not Thomas Mann or Bert Brecht, but the Prague Jew Franz Kafka.

Amerika102Kafka? You all know the photograph of the young Kafka, the one that shows him, his face slightly turned, looking with a smile of either uncertainty or mockery at a point just above the photographer’s lens. It is a detail from Kafka’s engagement photograph [shown here on right] with Felice Bauer from the year 1917 and it is the most famous image of the writer, the picture that everyone immediately thinks of, an absolute icon. I remember exactly what went through my head as I took my first steps in Kafka’s universe, I must have been fourteen or fifteen, as I looked at his face on the covers every day: he doesn’t look German. The dark skin, the thick eyebrows over black eyes, the short black hair reaching so far over his forehead as to hide all trace of his temples, the oriental traits. Today, of course, it would not be politically correct to say so, but at the time it was my immediate impression: he didn’t look German, not like the Germans I knew from school, from television, from the German national football team.

Beauty is in the eye of your friends

Debora MacKenzie in New Scientist:

FacesBen Jones at the University of Aberdeen in Scotland, and colleagues, showed 28 men and 28 women pairs of male faces and asked them to rate their attractiveness. The photos had been already been rated by 40 women as of about equal attractiveness.

The researchers then showed the same faces alongside a third photo of a female face in profile, positioned so she was looking at one of them, and smiling – or not. The viewers were asked to grade the faces again.

Women found the men who were being smiled at suddenly more attractive, while men who apparently elicited no such smiling approval were pronounced less attractive.

Psychologists are learning more about how colour builds language and language builds colour

From The Economist:

Rainbow_2Languages divide the spectrum up in different ways. Welsh speakers use “gwyrdd” (pronounced “goo-irrrth”) as a general word for green. Yet “grass” literally translates as “blue straw”. That is because the Welsh word for blue (“glas”) can accommodate all shades of green. English-speaking anthropologists affectionately squish “green” and “blue” together to call Welsh an example of a “grue” language. A few of them think grue languages are spoken by societies that live up mountains or near the equator because ultraviolet radiation, which is stronger in such places, causes a progressive yellowing of the lens. This, the theory goes, makes the eye less sensitive to short wavelengths (those that correspond to the green and blue parts of the spectrum). Unfortunately, though the Welsh do live in a hilly country, it is hardly mountainous enough—let alone sunny enough—to qualify.

The ultraviolet theory, however, is just one idea among many in the debate about the psychology of colour.

No Consolation For Kalashnikov

John Forge considers the moral dilemma of the weapons designer, in Philosophy Now:

Screenhunter_04_jan_21_1831The legendary AK 47 assault rifle was invented in 1946 by Mikhail Kalashnikov. It was issued to the armies of the old Warsaw Pact countries and has been used in many conflicts, eg by the North Vietnamese Army (NVA), Soviet soldiers in Afghanistan, and even this year by Al Qaeda operatives in Iraq. One might say that it was a good thing that the NVA had access to a reliable weapon in the face of the invading enemy forces, and that they were justified in using it to defend their homeland. One might also look at the Vietnam war some other way, but I will accept this interpretation here. On the other hand, it is much more difficult to argue that the Soviet forces had any right to invade Afghanistan. So we might contrast the uses to which the AK 47 was put in Vietnam with Afghanistan, and we could mark this contrast by saying that one was a just war waged by the NVA, and the other an unjust war waged by the Soviet Union. Whatever interpretation one puts on those two conflicts, almost no-one sane would condone the use of the AK 47 in killing civilians, for instance Shiites in Iraq.

Iran and the Bomb

Norman Dombey in the London Review of Books:

On 7 June 1981, Israeli aircraft bombed and completely destroyed the Iraqi nuclear research reactor Osirak. The French government, which had sold the reactor to Iraq, protested. Bertrand Barre, its nuclear attaché in Washington, explained that the reactor posed no proliferation risk and that ‘it was intended to be used . . . for testing or converting materials into isotopes, which have specialised uses in medicine.’ The UN Security Council strongly condemned the attack as being ‘in clear violation of the charter of the United Nations and the norms of international conduct’. The United States, however, objected to the imposing of any sanctions on Israel.

Was the Israeli attack on Osirak justified? Saddam Hussein certainly wanted to make nuclear weapons and in 1991 came dangerously close. But it is unlikely that he would have had much joy with Osirak, which relied on French technicians and was subject to International Atomic Energy Agency (IAEA) safeguards. Osirak used highly enriched uranium as fuel: 93 per cent uranium-235 (U-235), and 7 per cent U-238, so while the irradiated fuel rods could have been reprocessed to extract unused U-235, which is a fissile material suitable for weapons, there would have been little plutonium-239, which is obtained from the irradiation of U-238. Israel nevertheless claimed that Osirak was equipped to produce ‘military-grade plutonium in significant quantities’ and that they had to strike before the reactor went into operation. Iraq considered building a reactor to replace Osirak but settled instead for a clandestine uranium enrichment programme, which it didn’t declare to the IAEA.

Twenty-five years later, the focus is not on Iraq, but on Iran, which itself unsuccessfully bombed Osirak in September 1980. Israel and the US now claim that Iran is on the verge of obtaining nuclear weapons.

Can ageing be stopped?

From Prospect Magazine:

Age_10 Old age hardly exists in wild animals. Accident, illness or predation usually kill long before the potential lifespan has been reached. Humans, though, especially in the developed world, are pushing in ever larger numbers towards the maximum lifespan, thought by most gerontologists to be around 120. (The world longevity record is held by the Frenchwoman Jeanne Calment, who died in 1997 aged 122 years and 164 days.)

In Britain in 1901, life expectancy at birth was 49 for women and 45 for men. By 2002, this had risen to 81 and 76 respectively. This rapid increase in longevity has created hopes among gerontologists not just of an extended “quality of lifespan” well into the nineties, but of lifting the 120-year limit. The optimists point out that all animals have immortal reproductive cells (“germlines”), and argue that ageing and longevity are genetically determined through programmes that can in principle be amended. They argue that biology has the tools to cope with wear and tear almost indefinitely, if only there were an evolutionary route to get there.

Right now the optimists are in the ascendant, bolstered by recent experiments that have extended the life expectancy of mice from around two years to three, with some reports of up to five. (Picture).

Superbright Comet Sweeps Across Southern Skies

From The National Geographic:

Comet_1 Going blind isn’t usually a worry when watching for comets passing near Earth. But that’s what astronomers say could happen if people aren’t careful when they scan the skies for a glimpse of comet McNaught.

The comet is currently visible in the Southern Hemisphere near the horizon at dawn and dusk. It passes close to the sun, so observers are being cautioned not to accidentally gaze directly at the rising or setting star.

The fiery apparition—shown this morning through a gap in the clouds above Christchurch, New Zealand—is being touted as the brightest comet in 40 years, prompting crowds of hopeful amateurs to train their eyes on the sky.

ON THE HOLOCAUST CONFERENCE SPONSORED BY THE GOVERNMENT OF IRAN

Gholam Reza Afkhami and over one hundred others, in the New York Review of Books:

To the Editors:

We the undersigned Iranians,

Notwithstanding our diverse views on the Israeli–Palestinian conflict;

Considering that the Nazis’ coldly planned “Final Solution” and their ensuing campaign of genocide against Jews and other minorities during World War II constitute undeniable historical facts;

Deploring that the denial of these unspeakable crimes has become a propaganda tool that the Islamic Republic of Iran is using to further its own agendas;

Noting that the new brand of anti-Semitism prevalent in the Middle East today is rooted in European ideological doctrines of the nineteenth and twentieth centuries, and has no precedent in Iran’s history;

Emphasizing that this is not the first time that the government of the Islamic Republic of Iran has resorted to the denial and distortion of historical facts;

Recalling that this government has refused to acknowledge, among other things, its mass execution of its own citizens in 1988, when thousands of political prisoners, previously sentenced to prison terms, were secretly executed because of their beliefs;

Strongly condemn the Holocaust Conference sponsored by the government of the Islamic Republic of Iran in Tehran on December 11–12, 2006, and its attempt to falsify history;

Pay homage to the memory of the millions of Jewish and non-Jewish victims of the Holocaust, and express our empathy for the survivors of this immense tragedy as well as all other victims of crimes against humanity across the world.

Chinese anti-satellite weapon used simple technology

David Shiga in New Scientist:

China_weaponRelatively simple technology suffices to take out a satellite the way the Chinese government apparently did last week, space weapons analysts say. Essentially any country that can put a satellite in orbit could launch a weapon to destroy one.

The US government says China launched a ballistic missile on 11 January that destroyed one of its own spacecraft, a defunct weather satellite called Fengyun-1C, in an apparent test of anti-satellite technology (see China dismisses ‘space arms race’ fears).

This makes China one of just three nations in history to have successfully tested an anti-satellite weapon, along with the US and the former Soviet Union. But the technology required is not very sophisticated, potentially putting it in reach of other countries as well.

beautiful art at the frontier of science

Jim Holt in The New York Times:

On seeing the Alps for the first time, Dorothy Parker is reputed to have said, “They’re beautiful, but they’re dumb.” Near the foot of Mont Blanc, the greatest of the Alpine peaks, another sizable object is taking shape, also quite beautiful in its way, yet not at all dumb. In fact, its pristine geometries may be instrumental in revealing what have hitherto been some of nature’s deepest secrets.

letters of e.b. white

White190

“I’m the father of two robins,” E. B. White writes to his stepson in 1964 from his farm in Maine. The baby birds had been orphaned, “and without really thinking about what I was doing I casually dropped a couple of marinated worms into their throats as I walked by. … This did it. They took me on with open hearts and open mouths, and my schedule became extremely tight.” He has fed these robins a formula of “hamburg, chicken mash, kibbled worm and orange juice” for several days from a “yellow bamboo stick, split at one end, like a robin’s bill.” And now the birds “come streaming at me from bush and tree, trying for a landing on shoulder or cap, usually overshooting me in the fog and bringing up against a wall. This exhausts them and me.” Next, says White, he will have to “hop about on the lawn with my head cocked to one side, to show them how to get their own living.” That’s pretty good. It’s not twee or just whimsical, is it? No, it’s pretty good.

Bye-bye Hay Wain, hello the Somme

Kiefer983746

How do you like your contemporary art? A quick hit of juicy mischief, a larky take on mortality, binful of bluebottles, pocketful of glitter, everything you never wanted to know and more about the artist’s entrails? Right then, give Anselm Kiefer a very wide berth – because, as the show about to open at White Cube, London, will confirm, he doesn’t do droll, he does the big embarrassing stuff, the stuff that matters: the epic slaughters of the world, the incineration of the planet, apocalypse then, apocalypse often; the fragile endurance of the sacred amid the cauterised ruins of the earth.

Psycho Analyst: The Life of Masud Khan

From The New York Times:Masud_1

If I were a snob, a liar, a drunk, a philanderer, an anti-Semite, a violent bully, a poseur and a menace to the vulnerable, I would want Linda Hopkins to write my biography.

Masud Khan, an Anglo-Pakistani psychoanalyst notable in the 1960s and ’70s, was all of those things. Hopkins, a psychologist and psychoanalyst, has written the story of his life with the kind of generous forgiveness, insistent evenhandedness, patient understanding and restrained judgment one might hope for in a very good analyst of a certain kind, or a wise, exceptionally forbearing and insightful mother. She sees his life as a tragedy, lived “on a scale grand enough to match … his favorite characters: Shakespeare’s King Lear and Dostoyevsky’s Prince Myshkin.” Khan also identified with Dostoyevsky himself and was particularly pleased when one of his later girlfriends showed signs (briefly) of living up to the high benchmark of Anna Dostoyevsky’s devotion (“so robust and militant in her loving regard for her husband’s nobility of soul,” as he put it).

Hopkins describes Khan’s Dostoyevsky delusion as she does his lies about being a Pakistani prince; his drunken rages; his sleeping with patients, with patients’ wives and with the daughters of friends — always more in sorrow than in anger, and with the reminder that Khan may well have suffered from a bipolar disorder.

The science of pedestrian motion meets the annual Hajj in Mecca

From Nature:Mecca

The annual pilgrimage of Muslims to Mecca in Saudi Arabia, known as the Hajj, has on occasion been marred by deaths from trampling in the huge crowds that gather for the rituals. But scientists studying how pedestrians move around think they have made such crowd disasters much less likely.

In 2006, 362 people died in the crush that developed in the town of Mina, where pilgrims gather to perform a ritual stoning of pillars representing the devil as part of the Hajj. This year’s ritual, which happened in late December and early January, went off without incident. Although there have been plenty of other accident-free years, this time the reason owes more to sound planning than to luck, says Dirk Helbing of the Dresden University of Technology in Germany. Hebling and his coworkers used the science of crowd dynamics to introduce a raft of new crowd-control measures.

“This Hajj, in contrast to many previous ones, was very safe, without any panics or incidents, even though it was expected to be the most critical ever and there were about 800,000 more pilgrims than the expected 3 million,” he says. “This great success was due to a completely different organization of pilgrim flows.”

hybrid architecture

Mairi Beautyman in Interior Design:

Steven Holl Architects Wins AIA Honor Award
The University of Iowa School of Art & Art History building opened in September 2006.

Holl … The design team needed to incorporate an existing 1937 brick building and weave new construction with the area’s limestone bluffs, river, and lagoon.

Holl, the jury praised, “fought for the site and created something that has become a grounding point for the university.”

In September 2006, the building opened to international acclaim. According to architecture critic Blair Kamin, “Holl hasn’t just made a knock-your-eyes-out building…He’s made a real place, one that painters carting around their canvases actually seem to like.”

Among Holl’s additional arts projects are the Kiasma Museum of Contemporary Art (Helsinki, Finland) and the Nelson-Atkins Museum of Art in Kansas City, Missouri, slated to open in June.

Simon Garfield in The Observer:

More than 100 years after ‘word blindness’ was first discovered, thousands of children with great potential are still marginalised by an education system unable to cope with a common but silent disorder. Simon Garfield investigates the symptoms, treatment and prognosis of dyslexia

In a small room at the physiology department of the University of Oxford a man is being tested for dyslexia. This is an elaborate, detailed and standardised process, and the tests get harder as the session unfolds. There are words to read: box, water, babies, cough, curiosity, tyrannical and catastrophe. There are words to spell, read aloud by the assessor: light, advice, anxiety, camouflage and acquiesce. There are red and white plastic cubes to be arranged in the same pattern as a diagram. There are dancing dots on a computer screen to be distinguished from dots that move in a different pattern. And then there is the Verbal Similarities test, which also begins simply. What do the following three things have in common? Shirt, socks, coat. Then this: clock, thermometer, ruler. And finally: uncertainly, hesitantly, irregularly.

Of brylcreem and a Triumph roadster

Julian Barnes in The New Yorker:

THE PAST CONDITIONAL
What Mother would have wanted.

Barnesohlbaum I don’t believe in God, but I miss Him. That’s what I say when the question is put. I once asked my brother, who has taught philosophy at Oxford, Geneva, and the Sorbonne, what he thought of such a statement, without revealing that it was my own. He replied with a single word: “Soppy.”

The person to begin with is my maternal grandmother, Nellie Louisa Scoltock, née Machin, who was a schoolteacher in Shropshire until she married my grandfather Bert Scoltock. Not Bertram, not Albert, just Bert: so christened, so called, so buried. He was a headmaster with a certain mechanical dash to him: a motorcycle-and-sidecar man, then the owner of a Lanchester, then, in retirement, the driver of a rather pompously sportif Triumph Roadster, with a three-person bench seat in front and two bucket seats when the top was down. By the time I knew my grandparents, they had retired and come south to be near their daughter. My grandmother went to the Women’s Institute: she pickled and bottled; she plucked and roasted the chickens and geese my grandfather raised. She was petite, outwardly unopinionated, with the thickened knuckles of old age; she needed soap to get her wedding ring off. Their wardrobe was full of home-knitted cardigans, Grandpa’s tending to feature more masculine cable-stitch. They were of that generation advised by dentists to have all their teeth out in one go. This was a normal rite of passage then: from being rickety-gnashered to fully porcelained in one leap, to all that buccal sliding and clacking, to social embarrassment and the foaming glass on the bedside table.

Neurobiologist Eric Kandel searches for memory, cell by cell

Samir S. Patel in Columbia Magazine:

Kandel1I 1955, Eric Kandel, a New York University medical student training as a psychiatrist, told Columbia University neurophysiologist Harry Grundfest, with whom he was taking a course, that he wanted to find where the id, ego, and superego live in the gelatinous folds of the brain. In Kandel’s recent book, In Search of Memory: The Emergence of a New Science of Mind (W.W. Norton, 2006), he recounts Grundfest’s patient response. “He explained that my hope of understanding the biological basis of Freud’s structural theory was far beyond the grasp of contemporary brain science,” Kandel writes. “Rather, he told me, to understand the mind we needed to look at the brain one cell at a time.”

The Beauty in Politics

In the Economist:

NAMED last week as his party’s candidate for the French presidential election, Nicolas Sarkozy faces an opponent, Ségolène Royal, who has the press drooling. “Dazzling” and “radiant”, she has been likened to a work of art (“Mona Lisa”) and a mythological figure (a “siren”).

Perhaps Mr Sarkozy should pay a visit to Chattanooga, Tennessee. The city’s former mayor, Bob Corker, faced a similar problem in his Senate race last November. He prevailed against a congressman, Harold Ford junior, who was once counted among the 50 “most beautiful” people on Washington’s Capitol Hill. In response, Mr Corker hurled one of the strangest insults in campaign history. He accused Mr Ford of being “an attractive young man”.

“This is not a beauty pageant,” Ms Royal’s detractors are fond of saying. But what makes them so sure? The days are gone when a person would “vote for a pig if his party put one up,” as one British voter put it in the 1950s. Today, politicians must be well-groomed animals, selling their personalities not their parties. Looks can have an especially powerful influence on the minority of floating voters who determine election results, says Linda Bilmes, a professor of government at America’s Harvard University.
