Revolutionary jet engine tested

From the BBC:

_41476306_hyshot_test_inf416A new jet engine designed to fly at seven times the speed of sound appears to have been successfully tested.

The scramjet engine, the Hyshot III, was launched at Woomera, 500km north of Adelaide in Australia, on the back of a two stage Terrier-Orion rocket.

Once 314km up, the Hyshot III fell back to Earth, reaching speeds analysts hope will have topped Mach 7.6 (9,000km/h).

It is hoped the British-designed Hyshot III will pave the way for ultra fast, intercontinental air travel.

An international team of researchers is presently analysing data from the experiment, to see if it met its objectives.

The scientists had just six seconds to monitor its performance before the £1m engine crashed into the ground.

Translation: Is the Whole World Watching?

Lorne Manly in the New York Times:

Manly4How you see something,” said Nigel Parsons, the managing director of Al Jazeera International, “depends very much on where you’re sitting.”

Those words could well serve as the manifesto for the channel, the English-language offspring of the polarizing pan-Arab network, which will make its debut in more than 40 million households in late May.

Addressing hundreds of journalists and academics who had come to Doha, Qatar, for the second Al Jazeera Forum, Mr. Parsons promised that the new channel — with its headquarters there and broadcast centers in Washington, London and Kuala Lumpur — will cover the stories and people that the Western-owned news media overlook. “We’re not going to be another CNN, BBC or Sky,” he told the attendees on the last day of January. “If we were, there’d be no point.” But, he added, “It’s not our position to tell viewers what to think.”

During a freewheeling question-and-answer session, the audience pressed him for details. With costs already surpassing a billion dollars, Al Jazeera is the most ambitious television network start-up in recent years. Will it be the first network to crack the Western monopoly on delivering news and opinion to a global audience? Will it provide an Arab and Muslim point of view to the rest of the world?

William Safire And Art That’s Good for You

Philip Kennicott in the Washington Post:

SafireIt used to be fairly easy to draw the political battle lines over art in America.

On one side, let’s call it the left, was a view of human creativity that emphasized confrontation and paradigm busting, that reveled in political provocation and performance art, experimental theater and German opera directors, and could be found, reliably every two years, in the Whitney Biennial. On the other, let’s call it the right, was a view of art as affirmative and pretty, that favored arts that were popular enough to be commercial, and most of the traditional performing arts, and could be found on a nightly basis at places like the Kennedy Center. This basic cultural fissure was only deepened by the right-wing assault on the National Endowment for the Arts in the early 1990s and the failed left-wing efforts to push back with yet more provocation and confrontation.

If this is an accurate picture of art in America, then conservative pundit William Safire’s delivery on Monday of the 19th annual Nancy Hanks Lecture on Arts and Public Policy is something of an anomaly.

Bosses in love with claptrap and blinded by ideologies

Simon Caulkin in The Observer:

Heroic leaders are a disaster. Seventy per cent of mergers fail. In most organisations, financial incentives cause more problems than they solve. There is no connection between high executive pay and company performance (well, there is – the wider the pay differentials, the lower the commitment of the less well paid). The main result of many consultancy assignments is another consultancy assignment. All ‘silver bullet’ or ‘big ideas’ on their own are wrong.

These are not theories, but facts. Yet companies trip over themselves to buy others, launch change initiatives, introduce pay for performance, flit from one big idea to the next – and pay their CEOs stratospherically. It’s hardly surprising so many go belly up. If doctors were as cavalier with the evidence, a lot of their patients would be dead and many medics would be behind bars.

The last is a line from what bids fair to be one of the management books of the year. Hard Facts, Dangerous Half-Truths and Total Nonsense (Harvard Business School Press), by Stanford professors Jeffrey Pfeffer and Robert Sutton, is a compelling tour of management conventional wisdom and why it so often turns out to be unwise, untrue and a stranger to fact – bollocks, in fact. Every potential manager should be made to read it before they are allowed to be in charge of anything, even a whelk stall.

French Youth Revolt for the Status Quo

Henri Astier examines the large and ongoing demonstrations by French youth over the proposed change in the labor code, in openDemocracy.

France is undergoing another social convulsion, as hundreds of thousands of students and young people – now joined by the children of immigrants from the deprived banlieues – protest against a new law designed to increase the flexibility of the labour market. Some, like Naima Bouteldja, see the demonstrators as resisting the “flexploitation” characteristic of “the authoritarian market society France has become”; others, like the veteran of the 1968 protests (and current Green member of the European parliament) Danny Cohn-Bendit, portray their actions as “defensive, based on fear of insecurity and change”.

These contrasting perspectives reflect the fractures at the heart of current French social experience. Every country has its “haves” and “have-nots”, but in France the have-nots are a particularly desperate lot…

[U]nemployment is only part of the story. Millions more are caught on a treadmill of short-term schemes – mostly subsidised by the government – that lead either nowhere or to another dead-end job. Add those living off various welfare benefits, and the number of people relegated to the margins of French society has been variously estimated at a staggering 7-12 million.

The real fracture sociale Jacques Chirac referred to when he was elected president in 1995 – and has gone on to do nothing about – is between “insiders” with well-paid, secure positions, and “outsiders” who find it extremely difficult to get on the career path many take for granted in other countries.

International Cosmetic Assistance, a Review of The Beauty Academy of Kabul

In Variety, Ronnie Scheib reviews Liz Mermin’s The Beauty Academy of Kabul.

In an act of “selfless service,” a group of American women, backed by industry giants like Clairol and Vogue, open a beauty school in war-ravaged Afghanistan in “Beauty Academy of Kabul.” The anomalies are manifold: Gun-toting soldiers patrolling the streets are visible through the windows as rookie beauticians busily snip, perm and tweeze. Although helmer Liz Mermin’s straight-faced adherence to her subject tends to diffuse the cultural dissonance the pic reveals, docu’s feminist optimism should still serve Wellspring well domestically, while pic retains enough absurdist contradictions to satisfy cynical European auds.

Mermin achieves an easy intimacy with students and instructors alike. Pic alternates between scenes in the elegant academy, where the mindsets of the teachers dominate, and visits to the home salons of their various Afghan students, most of whom have husbands and children, where quite another set of values holds sway.

Critical thinking

From The Guardian:

Fukuyamasmall After the Neocons: America at the Crossroads by Francis Fukuyama. This book is a brutal critique of neoconservatism as practised by the Bush administration: and it is all the more damaging for the fact that Francis Fukuyama has himself been strongly identified with the neo-conservative cause. His tone is measured but the comprehensive nature of his demolition of Bush’s foreign policy leaves it – and neo-conservatism – in tatters. What, of course, has really done for Bush is “events”, above all those in Iraq. Rarely has a policy been exposed so rapidly and comprehensively on such a grand scale, but then wars have a habit of doing precisely that: the rhetoric and platitudes are suddenly and mercilessly subject to the cold test of reality.

The invasion of Iraq has failed so comprehensively that it seems bound to stimulate much soul-searching in Washington over the coming years. The defeat in Vietnam had a long-lasting effect on American foreign policy: the Mesopotamian disaster may come to be seen in not dissimilar terms.

Testicle cells may aid research

From BBC News:Stem_cells

Stem cells hold great promise for new treatments for many conditions as they have the ability to become many different types of adult tissue. But at present the most flexible type is found in human embryos – and their use is mired in controversy. A German team describe in the journal Nature how they isolated cells from mice testes that seem equally useful. The researchers, from the Georg August University in Gottingen, isolated sperm-producing cells from the testes of adult mice. They were able to show that, under certain culture conditions, some of them grew into colonies much like embryonic stem cells.

Wanted: A Few Good Sperm

Jennifer Egan in the New York Times Magazine:

19coverSperm donors, like online daters, answer myriad questions about heroes, hobbies and favorite things. Karyn read her donor’s profile and liked what she saw. “You can tell he comes from a warm family, some very educated,” she said. He had worked as a chef. He had “proven fertility,” meaning that at least one woman conceived using his sperm. Like all sperm donors, he was free from any sexually transmitted diseases or testable genetic disorders. “People in New York change sex partners quicker than the crosstown bus,” Karyn said. “I’d be a lot more concerned about my date next week.” But she especially liked the fact that he was an identity-release donor (also called an “open donor” or a “yes donor”) — a growing and extremely popular category of sperm donors who are willing to be contacted by any offspring who reach the age of 18.

Ernest Hemingway, secret agent

Peter Moreira in the Toronto Star:

060319_e_hemingway_300Hemingway, however, caught the espionage bug in Asia and didn’t shake it until World War II ended. When he returned to Cuba, he headed an FBI-funded spy ring to monitor Spanish fifth columnists in Havana. Gellhorn nicknamed the operation “The Crook Factory.” After that, he loaded drinking buddies on to his fishing boat with guns and a bomb and plied the Caribbean looking for U-boats.

Later, in France, Hemingway headed a small band of irregulars that moved in tandem with other allied troops heading westward to Berlin.

Busting people for “public intoxication” in bars

William Saletan in Slate:

Texas is busting people for “public intoxication” in bars. Undercover agents have “infiltrated” 36 bars and arrested 30 drinkers. Explanations from the Texas Alcoholic Beverage Commission: 1) We’re doing it to stop drinkers before they get in a car. 2) Even if they’re not going to get in a car, maybe they’ll “walk out into traffic and get run over.” 3) Or maybe they’ll “jump off of balconies trying to reach a swimming pool and miss.” 4) Anyway, bars aren’t exempt from laws against public intoxication…

Smoking may increase a man’s risk of impotence by almost 40 percent. The correlation shows up in men who smoke more than a pack a day. Smoking up to 20 cigarettes a day correlated with a 24 increase in impotence. Theory: Nicotine and other related chemicals “diminish blood flow to the penis and blood pressure in it.” Bonus finding: Moderate alcohol consumption “significantly reduced” the risk of impotence.

Deliberative Polling and Policy

In the Boston Review, James Fishkin looks at the problems of transforming public opinion into policy and discusses a way of making better public opinion, “Deliberative Polling”, on which I posted earlier.

After seven decades of public-opinion research, we see both the power and the limitations of this vision. The power is that we can take the public’s pulse on almost every conceivable issue on a regular basis. The limitations come from what is being measured. Consider three basic limitations. First, while everyone may, in some sense, be “in one great room,” the room is so big that often no one is listening, and no one is motivated to think much about the issues. In the 1950s, the political economist Anthony Downs coined a term for this problem: “rational ignorance.” If I have but one vote or opinion out of millions, why should I spend a lot of time and effort becoming informed about complex policy questions? My individual vote or opinion will not make much difference. And most of us have more urgent demands on our time and attention. The public’s well-documented low levels of information might be regrettable to democratic theorists, but they are understandable given the incentives facing any individual citizen.

Second, sometimes the “opinions” reported in polls do not exist. Because respondents do not like to say “I don’t know,” they often pick an answer more or less at random. When George Bishop of the University of Cincinnati asked in surveys about the “Public Affairs Act of 1975,” the public offered opinions even though the act was fictional. (And when The Washington Post celebrated the fictional act’s 20th anniversary by proposing its repeal, the public offered opinions about that as well.) Of course, on some issues the public has well-formed opinions, but on many others their opinions may represent nothing more than spontaneous impressions.

A third limitation comes from the way people choose interlocutors and news sources. Even when people discuss politics or policy—and many Americans do—they tend to talk to people like themselves, from similar social spheres and often with similar views. When an intense issue divides the country and you know someone on the other side, you are more likely to discuss the weather than risk potentially unpleasant disagreements.

“Spirituality” and the Revival of Liberalism

In the Wilson Quarterly, Leigh Schmidt makes the case that hopes for the revival of liberalism rests in “spirituality”, itself an old and important American tradition.

America may be polarized, but in one activity its social critics have achieved a rare unanimity: lambasting American “spirituality” in all its New Age quirkiness and anarchic individualism. The range of detractors is really quite impressive. James A. Herrick, an evangelical Christian author, deplores the “new spirituality” as a mélange of Gnostics, goddess worshipers, and self-proclaimed UFO abductees out to usurp the place of Christianity: all told, a widespread but shallowly rooted challenge to the mighty religious inheritance of the West. The neoconservative pundit David Brooks of The New York Times thinks that a “soft-core spirituality,” with its attendant “psychobabble” and “easygoing narcissism,” is epidemic. Observers on the left are no less prone to alarm. One pair of such commentators warned recently that the rebranding of religion as “spirituality” is part of corporate capitalism’s “silent takeover” of the interior life, the sly mar keting of a private, consumerist faith in the service of global enterprise.

Even many scholars of religion have jumped on the bandwagon. Martin E. Marty, the widely esteemed historian of American Christianity and professor emeritus at the University of Chicago, published an opinion piece this past January in Christian Century in which he labeled the “spirituality” versus “religion” debate “a defining conflict of our time.” …

All this criticism of the “new spirituality” has obscured and diminished what is, in fact, an important American tradition, one in which spiritual journeying has long been joined to social and political progressivism. Emerson’s “endless seeker” was, as often as not, an abolitionist; Whitman’s “traveling soul,” a champion of women’s rights; Henry David Thoreau’s “hermit,” a challenger of unjust war. A good sense of the continuing moral and political import of this American vocabulary of the spirit comes from Barack Obama, the recently elected Democratic senator from Illinois. Obama has said that, despite the results of the 2004 election, it “shouldn’t be hard” to reconnect progressive politics with religious vision: “Martin Luther King did it. The abolitionists did it. Dorothy Day did it. . . . We don’t have to start from scratch.”

How Computer Science Is Changing the Scientific Method

In the Economist:

WHAT makes a scientific revolution? Thomas Kuhn famously described it as a “paradigm shift”—the change that takes place when one idea is overtaken by another, usually through the replacement over time of the generation of scientists who adhered to an old idea with another that cleaves to a new one. These revolutions can be triggered by technological breakthroughs, such as the construction of the first telescope (which overthrew the Aristotelian idea that heavenly bodies are perfect and unchanging) and by conceptual breakthroughs such as the invention of calculus (which allowed the laws of motion to be formulated). This week, a group of computer scientists claimed that developments in their subject will trigger a scientific revolution of similar proportions in the next 15 years.

That claim is not being made lightly. Some 34 of the world’s leading biologists, physicists, chemists, Earth scientists and computer scientists, led by Stephen Emmott, of Microsoft Research in Cambridge, Britain, have spent the past eight months trying to understand how future developments in computing science might influence science as a whole. They have concluded, in a report called “Towards 2020 Science”, that computing no longer merely helps scientists with their work. Instead, its concepts, tools and theorems have become integrated into the fabric of science itself. Indeed, computer science produces “an orderly, formal framework and exploratory apparatus for other sciences,” according to George Djorgovski, an astrophysicist at the California Institute of Technology…Stephen Muggleton, the head of computational bio-informatics at Imperial College, London, has, meanwhile, taken the involvement of computers with data handling one step further. He argues they will soon play a role in formulating scientific hypotheses and designing and running experiments to test them.

Here is the report “Towards 2020 Science”.

Climate Model Predicts Greater Melting, Submerged Cities

From Scienctific American:Rainbow

Over the past 30 years, temperatures in the Arctic have been creeping up, rising half a degree Celsius with attendant increases in glacial melting and decreases in sea ice. Experts predict that at current levels of greenhouse gases–carbon dioxide alone is at 375 parts per million–the earth may warm by as much as five degrees Celsius, matching conditions roughly 130,000 years ago. Now a refined climate model is predicting, among other things, sea level rises of as much as 20 feet, according to research results published today in the journal Science.

An Ointment in the Fly

From Science:Fly_3

Viruses are deceptive little buggers, mutating often to dodge their hosts’ immune defenses. Plants fight back using a weapon called RNA interference (RNAi), which rips apart the viral machinery. Now, a new study shows that fruit flies employ the same defense–the first example of animals using this antiviral strategy. According to a related study, the genes behind this resistance are evolving rapidly to keep up with an ever-changing adversary.

For most creatures, RNA is just the middle man that helps a gene make a protein. But many viruses can get by on RNA alone. When they invade a cell, their RNA infiltrates the host’s genetic machinery, tricking it into making viral proteins. Scientists knew that all cells can shred unwanted RNA using RNAi, but they had never observed living animals using this strategy to defend against viruses.

Marek Kohn

Interview in Ready Steady Book:

Marek Kohn is a Marekkohn_1writer who lives in Brighton. His most recent book, A Reason For Everything: Natural Selection and the English Imagination, looks at the key thinkers behind the development of evolutionary theory in Britain, and why these ideas have thrived better in Britain than in other countries. His previous books have looked at drug culture, race, and the evolution of the human mind. Marek Kohn was talking to Stuart Watkins and Dave Flynn.

RSB: In your most recent book, A Reason For Everything, you talk about the different impact Darwinian thinking has had in Britain compared with the rest of Europe and the US. How do you account for this difference?

Marek Kohn: The distinguishing feature of English evolutionary thought has been its attitude to adaptation. An adaptationist tends to see the work of natural selection in every aspect of an organism – a reason for everything. You see bands on a snail’s shell: you wonder what good the bands do for the snail. And you go out into the field, and you look for possible reasons for them. In the case of the snails there’s a camouflage effect – different coloured or banded shells are better suited to different habitats, such as leaf litter or grass. Not the whole story but a robust example of English adaptationism in practice.

The palaeontologist Stephen Jay Gould called this the British “hang-up”, and his colleague the geneticist Richard Lewontin said that it arose in large part from the fascination for butterflies, snails, birds and gardens typical of the pre-war upper middle class from whose ranks these scientists mostly came. True enough, though it doesn’t acknowledge the fascination with natural history that used to run right across the social spectrum. Also one can see its roots in Victorian natural history, which of course is where all this began. As Alfred Russel Wallace observed, it was a fascination with species and the subtle distinctions between them – beetle-collecting – that allowed him and Darwin to realise, independently, how natural selection works.

If by contrast your vision is shaped, as that of their counterparts on the continent was, by idealist philosophy, you are unlikely to see what is going on in nature. Idealism is concerned with ideal types and therefore discounts variation as ‘noise’. You need to be fascinated by variation to see natural selection, because variations are what nature selects.

Giving Children the Vote

Over at Lawyers, Guns and Money, djw has an interesting post on letting children vote.

When I teach American Political Thought, I close with what always turns out to be a vigorous class discussion on Michael S. Cummings essay “On Children’s Right to Vote”* which is a brief, uncompromising case for extending the franchise to those under 18. My pedagogical reason is clear–they’ve all had the luxury of being casually correct and shaking their heads in dismay at the various arguments and justifications for *not* extending the franchise and full citizenship to various oppressed groups. Reading this essay, rightly or wrongly, tends to put most of them on the side of tradition and exclusion. Even those who are 100% convinced the proposal is insane tend to find this new position they find themselves in rather uncomfortable.

But I want to talk briefly about Cummings argument (sorry, it’s not available online) because it’s surprisingly seductive. I’ll summarize it in a series of premises:

1) The exclusion of any group from the franchise requires positive justification, as exclusion based on tradition has a poor track record.

2) The argument that children would take the responsibility of voting less seriously than other groups is an argument we’d reject out of hand if applied to other groups, even if it were empirically demonstrable.

3) The argument that children generally aren’t full economic citizens with jobs and taxes is a) often untrue and more often partially true, and b) is also true of many adults, but we’d never tolerate arguments to disenfranchise the chronically unemployed or dependent adults, and c) is perhaps the point.

Learning from Athens

Josiah Ober in the Boston Review:

The great legacy of the 20th century may be the emergence of democracy as a universal value: the conviction that whenever people are subjected to power, their views about the exercise of that power must be taken into consideration. This democratic principle, it is now widely agreed, is a fundamental moral requirement on the governance of states, global institutions, and even nongovernmental organizations.

But if democracy is now generally regarded as morally superior to other forms of political organization, its effectiveness in delivering the goods remains a matter of sharp contest. How does democracy fare when it comes to assuring physical security, protecting health, and fostering economic growth? We know, for example, from the economist Amartya Sen that famines are all too common under authoritarian regimes but do not occur in democratic states with a free press. Yet Sen also acknowledges that we do not know the effects of democracy on economic growth: “If all the comparative studie s are viewed together, the hypothesis that there is no clear relation between economic growth and democracy in either direction remains extremely plausible.”

Democracy may be right, then, but is it good?

In the Jungle, the Unjust Jungle, a Small Victory

Sharon LaFraniere in the New York Times:

Africa184As Solomon Linda first recorded it in 1939, it was a tender melody, almost childish in its simplicity — three chords, a couple of words and some baritones chanting in the background.

But the saga of the song now known worldwide as “The Lion Sleeps Tonight” is anything but a lullaby. It is fraught with racism and exploitation and, in the end, 40-plus years after his death, brings a measure of justice. Were he still alive, Solomon Linda might turn it into one heck of a ballad…

Some 150 artists eventually recorded the song. It was translated into languages from Dutch to Japanese. It had a role in more than 13 movies. By all rights, Mr. Linda should have been a rich man.

Instead, he lived in Soweto with barely a stick of furniture, sleeping on a dirt floor carpeted with cow dung.

Mr. Linda received 10 shillings — about 87 cents today — when he signed over the copyright of “Mbube” in 1952 to Gallo Studios, the company that produced his record. He also got a job sweeping floors and serving tea in the company’s packing house.
