The Illogic of U.S. Foreign Language Education

In November of 1970, a thirteen-year-old girl arrived, accompanied by her mother, at a California family aid office. The girl, who is known publicly by the name “Genie,” walked hunched with her hands raised in front of her like paws. According to Susan Curtiss, author of Genie: a Psycholinguistic Study of a Modern-Day Wild Child, she weighed only 59 pounds and spat incessantly. In addition to her decrepit physical appearance and bizarre social habits, Genie seemed incapable of producing normal language – only ever uttering a few isolated words.

For the ten years leading up to that day in November, Genie had been confined to a single room – strapped, by day, to a “potty chair,” and, by night, to the inside of a sleeping bag. During that time, Genie had very limited human contact, and – of particular interest to the psychologists who studied her for the eight years to follow – almost no exposure to language. This fact – the occasion of Genie’s tragic abuse – gave scientists the opportunity investigate a question that could never have been probed through direct experimentation: does one lose the ability to acquire a first language?

Cases like Genie’s suggest that the answer is yes. While children who were deprived of linguistic stimuli up until age six have gone on to possess normal language, others, like Genie, whose deprivation continued past this point, have not had the same success. Genie did learn the meanings of many words, but she was never able to piece them together into sentences with normal syntax. Instead, she formed statements like “Applesauce buy store” and “I like elephant eat peanut.” Although controversies remain regarding Genie’s case (for instance, allegations of inconsistency in the documentation of Genie’s progress), the apparent linguistic limitations of so-called “feral children” offer strong evidence for a “critical period” after which it is impossible to acquire normal language.

The critical period hypothesis, which refers exclusively to first language acquisition, in turn suggests that children possess certain innate faculties which are crucial for (and, perhaps, specific to) the acquisition of language. This notion, which was brought to mainstream attention by Steven Pinker in his 1994 bestseller, The Language Instinct, is accepted in some form by most psycholinguists. However, a related question – one with even greater practical relevance – remains a point of controversy: does one lose the ability to acquire a second language?

Who is the biggest King of Fraud — Bernie Madoff or Henry Paulson? A common sense discussion in layman’s language of our casino capitalism, skeevy CEOs and Pollyanna Psychosis

1. Casino Capitalism — making money from money with other people's money

What financial toilet is our government trying to flush us out of? Here's the best explanation I've read of the cause of our trouble — toxic mortgage-backed derivatives — by independent trader Jeffrey Carter:

“The collateralized debt obligation that is talked about is like you selling your car to Joe, but not getting any money today for it. Joe is going to pay you next year. As soon as Joe gets your car, he rents it to Jim. Jim doesn’t pay him, but offers to pay him monthly for the use of the car. Jim sells the car to a chop shop. The chop shop pays Jim a commission, and sells pieces of the car at a profit to Tim, Tom, Dick, and Harry. Harry buys Dick’s pieces, and puts together a new car — but has an accident. How is Joe going to collect? Who really owns the car? Of course it’s more complicated than that, but you get the idea. The government is going to bail out everyone, or pick a person in the chain.”

Sounds like quite the merry malodorous mess, doesn't it? In fact, it's so stinky that Goldman Sachs, while they were selling these derivatives, were also shorting them — i.e. betting their own money that the poopscoops they were selling to trusting pension funds were bound to lose their value.

And they call Bernie Madoff a crook. “Casino capitalists” is the kindest, gentlest name for what Wall Street people have become. They don't produce anything, they don't back entrepreneurs, they don't start factories, they don't create useful products, they don't build stuff, they're not actual dinkum kosher capitalists. They just use other people's money to make more money out of money. In other words, they borrow-and-bet. The bottom-feeders of capitalism. Parasites. People who have decided that the best use of their entire lives is to make money off money with borrowed money.

And boy, have they coined it. The financial companies' share of corporate profits in 2007 was 40%. Think of that — 40% of profits came not from doing anything except play around with money. And now we know that what they bet on — and with — is mostly crap. How much ca-ca? In 2006, Wall Street earned $62 billion in bonuses. To earn that much, they parlayed derivatives or debt or crap all over the world to a degree that people say now starts at $85 trillion. The Iraq War will cost us around $1 trillion, so we're talking 85 Iraq Wars of debt here. (The derivatives market itself is supposed to be $500 trillion.) Poor Barack Obama: he thinks he's going to save us from $85 trillion of crap by printing an extra one trillion.

Culture in Development: The Importance of Climbing Up the Slide

A quiet, global community of researchers want to change how psychologists think about the mind and culture — or to put it a bit more precisely, they want to call attention to some almost forgotten ones. They publish their research in Culture & Psychology, whose founding editor is Jaan Valsiner. Professor Valsiner was kind enough to furnish us an interview via email. The text has been edited for style.

Jonathan Pfeiffer, 3quarksdaily: How does cultural developmental psychology help us to understand changes in human life, either from moment to moment or over the course of one's lifetime?

Jaan Valsiner: The idea of cultural developmental psychology is best captured in this photo. What do you see in it? Of course it is very ordinary; this is a toy gadget for children (but note the inscriptions we call “graffiti” on the sideboards — an arena for public art?). Slide In it you can see the world of adults, who invent such objects, build them, and take their children to the neighborhood park “to play” and deeply believe they are doing their best for their children, as the latter now can learn the “right ways” of behaving. But, of course, what they create in actuality are opportunities to act in new ways that are more challenging than the “right ways.” You can observe that when children play with this kind of slide and do many other things with many other toys, thus experimenting with the “contrarian movement.” They climb up the part of the structure where they are “supposed” to slide down. Any object of furniture is a culturally designed object that suggests to its users — children or adults alike — some socially preferred courses of action. Yet by that suggestion, these objects call forth counter-action to the opposite, resistance to suggestions, and in one word, creativity. If there were no people — children or adults — who would constructively “disobey” the socially suggested ways of being, then no new technologies or social changes could be possible.

Cultural developmental psychology is a basic science of human development from birth to death, covering the whole life course, that investigates the construction, use, and abandonment of the whole range of cultural tools in the dynamic life course of human beings: language, physical objects of everyday life, symbolic objects in public and private settings, and social roles people assume (mother, father, policeman, tax accountant, beggar, president, criminal, etc.).

(Not) Finding Room for Obama

Forrent2 On somehow failing to rent
my apartment for Inauguration.

Little boys crave taking sides for battles and banding together into little gangs, yet whenever I begged my father to tell me which side we wanted to win in football games on television (about as far as my notion of being a warrior extended then), he would shrug his shoulders. “I just want to see a good game,” he’d announce.

Judgerobes He served as a black-robed judge for a quarter century, and seemed to think that professional ethics bound him to maintain a strict judicial neutrality even on the Minnesota Vikings versus the Chicago Bears. “No, dad, come on! Who should win?” Who do we want to inspire us? Who should we give ourselves to?

“As long as it’s a good game, that’s all I want.” He’d eat some peanuts.

I hated that he left my brother and I so unmoored about our loyalties. We could have cheered for the local team and found solidarity with everyone else, or picked a division rival and defined ourselves as iconoclasts. We sat out.

Because I never had practice either immersing myself inside a crowd or fighting upstream against a crowd, I never understood crowd dynamics as a child, especially what makes people band together and willingly commit to someone or something. What inspires them? Why do they cheer? Willing commitment became an oasis for me, but like most oases it had qualities of a mirage. After undergoing such torture with my father, I never could judge if people were genuinely passionate about “their” team or just posing.

And this shouldn’t be dismissed as a trivial case. Trivial cases are practice for real life.

Landing in a clean, well-lighted place

Krzysztof Kotarski

“I have a thing with airports…”

“Be more specific, Kris.”

“Ok, let me start again.

“I first began to think about this after I saw the video of Robert Dziekanski getting killed in Vancouver… remember? He was the Polish guy who got Tasered by the police because he was acting all ‘agitated’ after hours and hours of being stuck in the international arrivals area where no one could tell him what to do.

“He was moving to Canada to be with his mother… he got on the plane, landed, but something went wrong. He got stuck in the no-man’s land between luggage and immigration, or immigration and luggage… you know how it goes. He did not speak enough English to get himself sorted out, so he was left to his own devices, he got frustrated, and eventually he got killed.”

“What did they shock him for?”

“Oh, who knows… they probably didn’t know any better… you have to understand, Canadian police… well, let’s just say that the best and brightest probably aren’t the ones patrolling airports at 1:30 in the morning. Someone gave them Tasers and they use them like toys. There were four of them, one of him, and rather than figuring out a way to talk to him or to put him down another way, they got their Tasers out and zapped the poor guy instead. I think they told him to put his hands down on a table, but he put his hands up instead. He didn’t speak a word of English, so… you know…

“I remember watching the news the next morning… the police were giving their own version of the story…. ‘he was agitated… public safety… officers acted as they were trained… will review…’ you know how they talk. I don’t think that this is different in any country—I remember watching the Brits try to explain themselves after they shot that poor Brazilian on the tube. Cops always say the same things after they screw up…

The Pervert’s Guide to Cinema

16pervert.xlarge1 Stephen Holden reviews Zizek's new movie:

In this globe-trotting documentary, directed by Sophie Fiennes (sister of Ralph and Joseph), Mr. Zizek, a blustery, excitable lecturer, is often filmed speaking on the actual locations of the films he discusses, or on recreated sets. We find him riding on a motorboat in Bodega Bay in northern California, the site of “The Birds,” and prowling around the locations of “Vertigo”; those are the two Hitchcock films besides “Psycho” to receive the closest scrutiny.

Like Freud’s division of the psyche into three parts, the movie unfolds in three loosely overlapping sections. The first examines how the movies arouse our desires and allow us to channel unconscious drives into entertaining thrills and chills. The shower drain in “Psycho” and the toilet bowl that backs up in Francis Ford Coppola’s conspiracy thriller “The Conversation,” he says, are vehicles for transporting evidence of our brute animal selves to a safe distance.

The second part examines sex and fantasy in movies and reaches some major conclusions: that sex is impossible without fantasy; that anxieties are the most authentic emotions we feel; and that fantasies, and by extension the movies that address them, are defenses against anxiety.

Part 3, which contemplates appearance versus reality in movies, explores the paradoxical scene from “The Wizard of Oz” in which the all-powerful Wizard is discovered to be an old man pontificating from behind a curtain. Even when the illusion of the Wizard’s omnipotence is exposed, Mr. Zizek theorizes, there is something more real in the illusion than in the reality behind it. And so when the old man hands the Scarecrow a diploma to prove he has a brain, the Scarecrow is convinced he is smart.

Mr. Zizek is a little bit like the Wizard.

Flat N All That

Matt Taibbi reviews Thomas Friedman's Hot, Flat and Crowded in the New York Press:

In The World is Flat, the key action scene of the book comes when Friedman experiences his pseudo-epiphany about the Flat world while talking with himself in front of InfoSys CEO Nandan Nilekani. In Hot, Flat and Crowded, the money shot comes when Friedman starts doodling on a napkin over lunch with Moisés Naím, editor of Foreign Policy magazine. The pre-lunching Friedman starts drawing, and the wisdom just comes pouring out:

I laid out my napkin and drew a graph showing how there seemed to be a rough correlation between the price of oil, between 1975 and 2005, and the pace of freedom in oil-producing states during those same years.

Friedman then draws his napkin-graph, and much to the pundit’s surprise, it turns out that there is almost an exact correlation between high oil prices and “unfreedom”! The graph contains two lines, one showing a rising and then descending slope of “freedom,” and one showing a descending and then rising course of oil prices.

Friedman plots exactly four points on the graph over the course of those 30 years. In 1989, as oil prices are falling, Friedman writes, “Berlin Wall Torn Down.” In 1993, again as oil prices are low, he writes, “Nigeria Privatizes First Oil Field.” 1997, oil prices still low, “Iran Calls for Dialogue of Civilizations.” Then, finally, 2005, a year of high oil prices: “Iran calls for Israel’s destruction.”Take a look for yourself: I looked at this and thought: “Gosh, what a neat trick!” Then I sat down and drew up my own graph, called SIZE OF VALERIE BERTINELLI’S ASS, 1985-2008, vs. HAP- PINESS. It turns out that there is an almost exact correlation! Note the four points on the graph:

The Rocky Road to Recovery

Stiglitz Joseph Stiglitz in Project Syndicate:

A consensus now exists that America’s recession – already a year old – is likely to be long and deep, and that almost all countries will be affected. I always thought that the notion that what happened in America would be decoupled from the rest of the world was a myth. Events are showing that to be so.

Fortunately, America has, at last, a president with some understanding of the nature and severity of the problem, and who has committed himself to a strong stimulus program. This, together with concerted action by governments elsewhere, will mean that the downturn will be less severe than it otherwise would be.

The United States Federal Reserve, which helped create the problems through a combination of excessive liquidity and lax regulation, is trying to make amends – by flooding the economy with liquidity, a move that, at best, has merely prevented matters from being worse. It’s not surprising that those who helped create the problems and didn’t see the disaster coming have not done a masterly job in dealing with it. By now, the dynamics of the downturn are set, and things will get worse before they get better.

In some ways, the Fed resembles a drunk driver who, suddenly realizing that he is heading off the road starts careening from side to side. The response to the lack of liquidity is ever more liquidity. When the economy starts recovering, and banks start lending, will they be able to drain the liquidity smoothly out of the system? Will America face a bout of inflation? Or, more likely, in another moment of excess, will the Fed over-react, nipping the recovery in the bud?

The Inaugural Poet

From The Root:

Elizabeth%20Alexander The selection of Yale professor and poet Elizabeth Alexander to write and deliver a poem at the inauguration of Barack Obama marks not only the return of poetry to a place of prominence in presidential history (she is only the fourth to read at a presidential swearing-in), but represents a true mind-meld between the president-elect and his chosen bard. Professor Alexander is a virtuosic writer and a shrewd analyst of American letters, a polyglot who moves fluently from essay to sonnet, from free verse to drama—and in her teaching, traces equally diverse themes. As the big day approaches, it’s hard to tell who will serve as muse to whom—Alexander and Obama share ties to Chicago and to the classroom, and a demonstrated commitment to the power of words and of community institutions.

I recently caught up with my former teacher to discuss her work and the now-finished poem she will deliver at Tuesday’s ceremony.

The Root: Congratulations! How were you chosen for the honor? Who called who?

Elizabeth Alexander: I actually don’t know! You’d have to ask the inaugural committee what happened. I just got a phone call saying that they were asking me to write a poem and deliver it. It was a tremendous thrill. Kind of like Sarah Palin, I didn’t even think about saying no.

I think one of the really exciting things about the Obama campaign and his election is that so many more people than in the past have felt called to serve, have felt that they needed to step up their game, do what they could. You know, not much has been asked of us in the last eight years—now is the time. So I thought that this question was a continuation of the same mission we heard expressed on the campaign trail.

A pointless war has led to a moral defeat for Israel

Gaza_klinik_DW_Poli_725145g

Editorial in The Observer:

The notion that the country's security problems can be resolved by the unilateral use of extreme force is a persistent delusion among Israeli politicians. In this case, the problem was perceived to be Hamas rocket fire into southern Israel; the solution was judged to be a war against Hamas. That analysis did not allow for the vital, humane recognition that, in densely populated Gaza, an all-out war against Hamas is, by necessity, an attack on the civilian population.

Even on its own terms, the campaign has failed. Israeli authorities will insist that they have limited the ability of Hamas to launch rocket attacks. But the ostensible war aim was destroying that capability completely.

Israel will also claim that its campaign has exposed a lack of support for Hamas in many Arab capitals; that Hamas' position as the ruling authority in Gaza has been undermined; and that Hamas has been revealed as little more than a terrorist proxy acting on behalf of and armed by Syria and Iran.

But the reality is that the status of Hamas as the preferred vehicle for Palestinian resistance to Israeli occupation has been enhanced by the indiscriminate brutality of the military assault.

Correspondence between Gideon Levy and A. B. Yehoshua

All three items below are from Haaretz. First, Gideon Levy:

The moral voice of restraint, if it ever existed, has been left behind. Even if Israel wiped Gaza off the face of the earth, killing tens of thousands in the process, as a Chechnyan laborer working in Sderot proposed to me, one can assume that there would be no protest.

They liquidated Nizar Ghayan? Nobody counts the 20 women and children who lost their lives in the same attack. There was a massacre of dozens of officers during their graduation ceremony from the police academy? Acceptable. Five little sisters? Allowed. Palestinians are dying in hospitals that lack medical equipment? Peanuts. Whatever happened to the not-so-good old days of Salah Shahadeh? When we liquidated him in July 2002, we also killed 15 women and children. At least back then, moral qualms were raised for a moment. Here lie their bodies, row upon row, some of them tiny. Our hearts have turned hard and our eyes have become dull. All of Israel has worn military fatigues, uniforms that are opaque and stained with blood and which enable us to carry out any crime. Even our leading intellectuals fail to speak out on what havoc we have wreaked. Amos Oz urges: “Cease-fire now.” David Grossman writes: “Hold your fire. Stop.” Meir Shalev wants “a punitive operation.” And not one word about our moral image, which has been horribly distorted.

More here. A. B. Yehoshua writes:

Dear Gideon,

You remember that in recent years I called you occasionally to praise you for your articles and your writing about the wrongs done to the Palestinians in the administered territories, whether by the army or by the settlers. Physical wrongs, land expropriations, acts of abuse, perversions of justice and so on. I told you that it is very difficult to read what you write, because it weighs on our conscience, but that the work you are doing and the voice you are sounding are extremely important. I was also concerned about your physical safety, knowing that you risked your life by visiting such hostile places.

I did not ask you why you did not visit Israeli hospitals in order to tell the painful stories of Israeli citizens who were hurt in terrorist attacks. I accepted your position that there are plenty of other journalists doing this and that you had taken on the crucial mission of telling the story of the afflictions of the other side, our enemies today and our neighbors tomorrow. Accordingly, it is from this position of respect that I find it necessary to respond to your recent articles on the war in which we are engaged today, so that you will be able to preserve the moral validity of your distinctive voice for the future. A few years ago, when the Hatuel family – a mother and her four children, of blessed memory – were killed on the way to one of the settlements in Gush Katif, I believed that this terrible death pained you as it did all of us but that like many of us you said in your heart: Why should these Israelis endanger their children by living provocatively, hopelessly, dangerously and immorally in Gush Katif? By what right do 8,000 Jews expropriate a sizable area in the densely overcrowded Gaza Strip in order to build blossoming villages before the eyes of hundreds of thousands of refugees living in such abysmal conditions? You were angry, as I was, at the parents and at those who sent them. And even though I believe that like all of us you felt the pain of the children who were killed, you did not brand the leaders of Hamas “war criminals” as you did the Israeli leaders, and you did not demand the establishment of an international tribunal to try them. When I asked you after the disengagement from Gaza, Gideon, explain to me why they are firing missiles at us, you replied that they want us to open the crossings. I asked you whether you truly believe that if they fire missiles the crossings will be opened, or the opposite. And whether you truly believe that it is right and just to open crossings into Israel for those who declare openly and sincerely that they want to destroy our country. I did not get an answer from you. And even though the crossings were in fact opened many times, and were closed in the wake of the missile attacks, regrettably I still did not see you standing firmly behind a moral position which says: Now, people of Gaza, after you expelled the Israeli occupation from your land, and justly so, you must hold your fire.

More here. Gideon Levy replies:

Dear Bulli,

Thank you for your frank letter and kind words. You wrote it was written from a “position of respect,” and I, too, deeply respect your wonderful literary works. But, unfortunately, I have a lot less respect for your current political position. It is as if the mighty, including you, have succumbed to a great and terrible conflagration that has consumed any remnant of a moral backbone.

You, too, esteemed author, have fallen prey to the wretched wave that has inundated, stupefied, blinded and brainwashed us. You're actually justifying the most brutal war Israel has ever fought and in so doing are complacent in the fraud that the “occupation of Gaza is over” and justifying mass killings by evoking the alibi that Hamas “deliberately mingles between its fighters and the civilian population.” You are judging a helpless people denied a government and army – which includes a fundamentalist movement using improper means to fight for a just cause, namely the end of the occupation – in the same way you judge a regional power, which considers itself humanitarian and democratic but which has shown itself to be a brutal and cruel conqueror. As an Israeli, I cannot admonish their leaders while our hands are covered in blood, nor do I want to judge Israel and the Palestinians the same way you have.

The residents of Gaza have never had ownership of “their own piece of land,” as you have claimed. We left Gaza because of our own interests and needs, and then we imprisoned them. We cut the territory off from the rest of the world and the occupied West Bank, and did not permit them to construct an air or sea port. We control their population registrar and their currency – and having their own military is out of the question – and then you argue that the occupation is over? We have crushed their livelihood, besieged them for two years, and you claim they “have expelled the Israeli occupation”? The occupation of Gaza has simply taken on a new form: a fence instead of settlements. The jailers stand guard on the outside instead of the inside.

The frat boy ships out

From The Economist:

ScreenHunter_04 Jan. 18 14.40 He leaves the White House as one of the least popular and most divisive presidents in American history. At home, his approval rating has been stuck in the 20s for months; abroad, George Bush has presided over the most catastrophic collapse in America’s reputation since the second world war. The American economy is in deep recession, brought on by a crisis that forced Mr Bush to preside over huge and unpopular bail-outs.

America is embroiled in two wars, one of which Mr Bush launched against the tide of world opinion. The Bush family name, once among the most illustrious in American political life, is now so tainted that Jeb, George’s younger brother, recently decided not to run for the Senate from Florida. A Bush relative describes family gatherings as “funeral wakes”.

The Naming of Parts
Henry Reed

Today we have naming of parts. Yesterday,
We had daily cleaning. And tomorrow morning,
We shall have what to do after firing. But today,
Today we have naming of parts. Japonica
Glistens like coral in all of the neighboring gardens,
And today we have naming of parts.

This is the lower sling swivel. And this
Is the upper sling swivel, whose use you will see,
When you are given your slings. And this is the piling swivel,
Which in your case you have not got. The branches
Hold in the gardens their silent, eloquent gestures,
Which in our case we have not got.

This is the safety-catch, which is always released
With an easy flick of the thumb. And please do not let me
See anyone using his finger. You can do it quite easy
If you have any strength in your thumb. The blossoms
Are fragile and motionless, never letting anyone see
Any of them using their finger.

And this you can see is the bolt. The purpose of this
Is to open the breech, as you see. We can slide it
Rapidly backwards and forwards: we call this
Easing the spring. And rapidly backwards and forwards
The early bees are assaulting and fumbling the flowers
They call it easing the Spring.

They call it easing the Spring: it is perfectly easy
If you have any strength in your thumb: like the bolt,
And the breech, and the cocking-piece, and the point of balance,
Which in our case we have not got; and the almond-blossom
Silent in all of the gardens and the bees going backwards and forwards,
For today we have naming of parts.

One Nation, After All

From The Washington Post:

Book Barack Obama's historic struggle to become the nation's first black president is over, but the fight over the meaning of his victory has only begun. In What Obama Means — one of what will certainly be many efforts to interpret and define the Obama phenomenon — Jabari Asim argues that Obama's victory is the culmination of decades of black political struggle, social advancement and cultural achievement. Obama promises to continue this cultural transformation with a new style of racial politics: more productive and less antagonistic than that of the “charlatans and camera hogs with whom we are all too familiar” (a group in which the Reverends Al Sharpton and Jesse Jackson figure prominently) but no less committed to social justice. Asim, editor of the NAACP's journal the Crisis and former deputy editor of Book World, insists that Obama is the latest and most inspiring of a long line of “dedicated champions of black advancement.” Because of Obama “it's becoming cool to be thoughtful, temperate and monogamous,” writes Asim, and Americans “may come to associate blackness with brilliance, thoughtfulness, confidence, and radical optimism.”

By contrast, Obama's detractors, left and right, have suggested that the new president inevitably will be limited by the racial politics of the past. Last year the conservative commentator Shelby Steele argued in A Bound Man that Obama was tethered, by his liberal ideology and racial loyalty, to a counterproductive politics of grievance that exaggerates white racism and denies the need for individual responsibility among blacks. By contrast, left-leaning black social commentators such as Cornel West, Tavis Smiley and Jesse Jackson have complained that, to win elections, Obama pandered to white voters, ignoring his responsibility to blacks.

Where Does the Entropy Go?

Sean Carroll in Cosmic Variance:

ScreenHunter_02 Jan. 18 10.28 Gravity is a weak force, which makes it extremely difficult to do actual experiments (or perform astronomical observations) that would give us any detailed, up-close-and-personal data about the behavior of quantum gravity. We should be thankful, therefore, that we’ve been able to learn as much as we have about quantum gravity (and we do know some things) just by sitting in our chairs and doing thought experiments, constrained only by the basic principles of general relativity and quantum mechanics. Undoubtedly the most prolific thought-experiment laboratories have been black holes. In particular, Hawking’s discovery that black holes radiate and have entropy has driven an enormous amount of research, and some of it has actually been productive! One of the highlights was certainly the calculation in 1996 by Strominger and Vafa, who used some tricks from string theory to actually count the number of quantum states hidden in a black hole, in a way that would have made Boltzmann proud, and come up with an answer that matched Hawking’s formula precisely.

There are still puzzles, however, as you might guess. Foremost among them is “How does the information get out?” An increasing number of physicists believe that the evaporation of black holes conserves information, but they don’t know precisely how the details of the state which created the black hole get preserved and then encoded in the outgoing Hawking radiation.

The Gaza offensive has succeeded in punishing the Palestinians but not in making Israel more secure

John J. Mearsheimer in the American Conservative:

ScreenHunter_01 Jan. 18 10.08 The campaign in Gaza is said to have two objectives: 1) to put an end to the rockets and mortars that Palestinians have been firing into southern Israel since it withdrew from Gaza in August 2005; 2) to restore Israel’s deterrent, which was said to be diminished by the Lebanon fiasco, by Israel’s withdrawal from Gaza, and by its inability to halt Iran’s nuclear program.

But these are not the real goals of Operation Cast Lead. The actual purpose is connected to Israel’s long-term vision of how it intends to live with millions of Palestinians in its midst. It is part of a broader strategic goal: the creation of a “Greater Israel.” Specifically, Israel’s leaders remain determined to control all of what used to be known as Mandate Palestine, which includes Gaza and the West Bank. The Palestinians would have limited autonomy in a handful of disconnected and economically crippled enclaves, one of which is Gaza. Israel would control the borders around them, movement between them, the air above and the water below them.

The key to achieving this is to inflict massive pain on the Palestinians so that they come to accept the fact that they are a defeated people and that Israel will be largely responsible for controlling their future. This strategy, which was first articulated by Ze’ev Jabotinsky in the 1920s and has heavily influenced Israeli policy since 1948, is commonly referred to as the “Iron Wall.”

What has been happening in Gaza is fully consistent with this strategy.
