Just Another Week at Fermilab

Another day, another particle, courtesy of scientists at Fermilab. The CDF group working with data from Fermilab’s Tevatron particle collider announced the finding of a new, neutron-like particle last week. The particle known as a neutral Xi-sub-b is a heavy relative of the neutron and is made up of a strange quark, an up quark and a bottom quark, hence the “s-u-b” moniker.

[div class=attrib]Here’s more from Symmetry Breaking:[end-div]

While its existence was predicted by the Standard Model, the observation of the neutral Xi-sub-b is significant because it strengthens our understanding of how quarks form matter. Fermilab physicist Pat Lukens, a member of the CDF collaboration, presented the discovery at Fermilab on Wednesday, July 20.

The neutral Xi-sub-b is the latest entry in the periodic table of baryons. Baryons are particles formed of three quarks, the most common examples being the proton (two up quarks and a down quark) and the neutron (two down quarks and an up quark). The neutral Xi-sub-b belongs to the family of bottom baryons, which are about six times heavier than the proton and neutron because they all contain a heavy bottom quark. The particles are produced only in high-energy collisions, and are rare and very difficult to observe.

Although Fermilab’s Tevatron particle collider is not a dedicated bottom quark factory, sophisticated particle detectors and trillions of proton-antiproton collisions have made it a haven for discovering and studying almost all of the known bottom baryons. Experiments at the Tevatron discovered the Sigma-sub-b baryons (?b and ?b*) in 2006, observed the Xi-b-minus baryon (?b) in 2007, and found the Omega-sub-b (?b) in 2009.

Bad reasoning about reasoning

[div class=attrib]By Massimo Pigliucci at Rationally Speaking:[end-div]

A recent paper on the evolutionary psychology of reasoning has made mainstream news, with extensive coverage by the New York Times, among others. Too bad the “research” is badly flawed, and the lesson drawn by Patricia Cohen’s commentary in the Times is precisely the wrong one.

Readers of this blog and listeners to our podcast know very well that I tend to be pretty skeptical of evolutionary psychology in general. The reason isn’t because there is anything inherently wrong about thinking that (some) human behavioral traits evolved in response to natural selection. That’s just an uncontroversial consequence of standard evolutionary theory. The devil, rather, is in the details: it is next to impossible to test specific evopsych hypotheses because the crucial data are often missing. The fossil record hardly helps (if we are talking about behavior), there are precious few closely related species for comparison (and they are not at all that closely related), and the current ecological-social environment is very different from the “ERE,” the Evolutionarily Relevant Environment (which means that measuring selection on a given trait in today’s humans is pretty much irrelevant).
That said, I was curious about Hugo Mercier and Dan Sperber’s paper, “Why do humans reason? Arguments for an argumentative theory,” published in Behavioral and Brain Sciences (volume 34, pp. 57-111, 2011), which is accompanied by an extensive peer commentary. My curiosity was piqued in particular because of the Times’ headline from the June 14 article: “Reason Seen More as Weapon Than Path to Truth.” Oh crap, I thought.

Mercier and Sperber’s basic argument is that reason did not evolve to allow us to seek truth, but rather to win arguments with our fellow human beings. We are natural lawyers, not natural philosophers. This, according to them, explains why people are so bad at reasoning, for instance why we tend to fall for basic mistakes such as the well known confirmation bias — a tendency to seek evidence in favor of one’s position and discount contrary evidence that is well on display in politics and pseudoscience. (One could immediately raise the obvious “so what?” objection to all of this: language possibly evolved to coordinate hunting and gossip about your neighbor. That doesn’t mean we can’t take writing and speaking courses and dramatically improve on our given endowment, natural selection be damned.)

The first substantive thing to notice about the paper is that there isn’t a single new datum to back up the central hypothesis. It is one (long) argument in which the authors review well known cognitive science literature and simply apply evopsych speculation to it. If that’s the way to get into the New York Times, I better increase my speculation quotient.

Higgs Particle Collides with Modern Art

Jonathan Jones over at the Guardian puts an creative spin (pun intended) on the latest developments in the world of particle physics. He suggests that we might borrow from the world of modern and contemporary art to help us take the vast imaginative leaps necessary to understand our physical world and its underlying quantum mechanical nature bound up in uncertainty and paradox.

Jones makes a good point that many leading artists of recent times broke new ground by presenting us with an alternate reality that demanded a fresh perspective of the world and what lies beneath. Think Picasso and Dali and Miro and Twombly.

[div class=attrib]From Jonathan Jones for the Guardian:[end-div]

The experiments currently being performed in the LHC are enigmatic, mind-boggling and imaginative. But are they science – or art? In his renowned television series The Ascent of Man, the polymath Jacob Bronowski called the discovery of the invisible world within the atom the great collective achievement of science in the 20th century. Then he went further. “No – it is a great, collective work of art.”

Niels Bohr, who was at the heart of the new sub-atomic physics in the early 20th century, put the mystery of what he and others were finding into provocative sayings. He was very quotable, and every quote stresses the ambiguity of the new realm he was opening up, the realm of the smallest conceivable things in the universe. “If quantum mechanics hasn’t profoundly shocked you, you haven’t understood it yet,” ran one of his remarks. According to Bronowski, Bohr also said that to think about the paradoxical truths of quantum mechanics is to think in images, because the only way to know anything about the invisible is to create an image of it that is by definition a human construct, a model, a half-truth trying to hint at the real truth.

. . .

We won’t understand what those guys at Cern are up to until our idea of science catches up with the greatest minds of the 20th century who blew apart all previous conventions of thought. One guide offers itself to those of us who are not physicists: modern art. Bohr, explained Bronowski, collected Cubist paintings. Cubism was invented by Pablo Picasso and Georges Braque at the same time modern physics was being created: its crystalline structures and opaque surfaces suggest the astonishment of a reality whose every microcosmic particle is sublimely complex.

Rechargeable Nanotube-Based Solar Energy Storage

[div class=attrib]From Ars Technica:[end-div]

Since the 1970s, chemists have worked on storing solar energy in molecules that change state in response to light. These photoactive molecules could be the ideal solar fuel, as the right material should be transportable, affordable, and rechargeable. Unfortunately, scientists haven’t had much success.

One of the best examples in recent years, tetracarbonly-diruthenium fulvalene, requires the use of ruthenium, which is rare and expensive. Furthermore, the ruthenium compound has a volumetric energy density (watt-hours per liter) that is several times smaller than that of a standard lithium-ion battery.
Alexie Kolpak and Jeffrey Grossman from the Massachusetts Institute of Technology propose a new type of solar thermal fuel that would be affordable, rechargeable, thermally stable, and more energy-dense than lithium-ion batteries. Their proposed design combines an organic photoactive molecule, azobenzene, with the ever-popular carbon nanotube.

Before we get into the details of their proposal, we’ll quickly go over how photoactive molecules store solar energy. When a photoactive molecule absorbs sunlight, it undergoes a conformational change, moving from the ground energy state into a higher energy state. The higher energy state is metastable (stable for the moment, but highly susceptible to energy loss), so a trigger—voltage, heat, light, etc.—will cause the molecule to fall back to the ground state. The energy difference between the higher energy state and the ground state (termed ?H) is then discharged. A useful photoactive molecule will be able to go through numerous cycles of charging and discharging.

The challenge in making a solar thermal fuel is finding a material that will have both a large ?H and large activation energy. The two factors are not always compatible. To have a large ?H, you want a big energy difference between the ground and higher energy state. But you don’t want the higher energy state to be too energetic, as it would be unstable. Instability means that the fuel will have a small activation energy and be prone to discharging its stored energy too easily.

Kolpak and Grossman managed to find the right balance between ?H and activation energy when they examined computational models of azobenzene (azo) bound to carbon nanotubes (CNT) in azo/CNT nanostructures.

Postcards from the Atomic Age

Remember the lowly tourist postcard? Undoubtedly, you will have sent one or two “Wish you where here!” missives to your parents or work colleagues while vacationing in the Caribbean or hiking in Austria. Or, you may still have some in a desk drawer. Remember, those that you never mailed because you had neither time or local currency to purchase a stamp. If not, someone in your extended family surely has a collection of old postcards with strangely saturated and slightly off-kilter colors, chronicling family travels to interesting and not-so-interesting places.

Then, there are postcards of a different kind, sent from places that wouldn’t normally spring to mind as departure points for a quick and trivial dispatch. Tom Vanderbilt over at Slate introduces us to a new book, Atomic Postcards:

“Having a great time,” reads the archetypical postcard. “Wish you were here.” But what about when the “here” is the blasted, irradiated wastes of Frenchman’s Flat, in the Nevada desert? Or the site of America’s worst nuclear disaster? John O’Brian and Jeremy Borsos’ new book, Atomic Postcards, fuses the almost inherently banal form of the canned tourist dispatch with the incipient peril, and nervously giddy promise, of the nuclear age. Collected within are two-sided curios spanning the vast range of the military-industrial complex—”radioactive messages from the Cold War,” as the book promises. They depict everything from haunting afterimages of atomic incineration on the Nagasaki streets to achingly prosaic sales materials from atomic suppliers to a gauzy homage to the “first atomic research reactor in Israel,” a concrete monolith jutting from the sand, looking at once futuristic and ancient. Taken as a whole, the postcards form a kind of de facto and largely cheery dissemination campaign for the wonder of atomic power (and weapons). And who’s to mind if that sunny tropical beach is flecked with radionuclides?

“Spectacular nuclear explosion” reads a caption on the back (or “verso,” as postcard geeks would say) of this card—released by “Ray Helberg’s Pacific Service”—of a test in the Marshall Islands. The disembodied cloud—a ferocious water funnel of water thrust upward, spreading into a toroid of vapor—recalls a Dutch sea painting with something new and alien in its center. “Quite a site [sic] to watch,” reads a laconic comment on the back. Outside the frame of the stylized blast cloud are its consequences. As Nathan Hodge and Sharon Weinberg write in Nuclear Family Vacation, “[F]or the people of the Marshall Islands, the consequences of atomic testing in the Pacific were extraordinary. Traditional communities were displaced by the tests; prolonged exposure to radiation created a legacy of illness and disease.”

Is Anyone There?

[div class=attrib]From the New York Times:[end-div]

“WHEN people don’t answer my e-mails, I always think maybe something tragic happened,” said John Leguizamo, the writer and performer, whose first marriage ended when his wife asked him by e-mail for a divorce. “Like maybe they got hit by a meteorite.”

Betsy Rapoport, an editor and life coach, said: “I don’t believe I have ever received an answer from any e-mail I’ve ever sent my children, now 21 and 18. Unless you count ‘idk’ as a response.”

The British linguist David Crystal said that his wife recently got a reply to an e-mail she sent in 2006. “It was like getting a postcard from the Second World War,” he said.

The roaring silence. The pause that does not refresh. The world is full of examples of how the anonymity and remove of the Internet cause us to write and post things that we later regret. But what of the way that anonymity and remove sometimes leave us dangling like a cartoon character that has run off a cliff?

For every fiery screed or gushy, tear-streaked confession in the ethersphere, it seems there’s a big patch of grainy, unresolved black. Though it would comfort us to think that these long silences are the product of technical failure or mishap, the more likely culprits are lack of courtesy and passive aggression.

“The Internet is something very informal that happened to a society that was already very informal,” said P. M. Forni, an etiquette expert and the author of “Choosing Civility.” “We can get away with murder, so to speak. The endless amount of people we can contact means we are not as cautious or kind as we might be. Consciously or unconsciously we think of our interlocutors as disposable or replaceable.”

Judith Kallos, who runs a site on Internet etiquette called netmanners.com, said the No. 1 complaint is that “people feel they’re being ignored.”

The five top regrets of dying people

Social scientists may have already examined the cross-cultural regrets of those nearing end of life. If not, it would make fascinating reading to explore the differences and similarities. However, despite the many traits and beliefs that divide humanity, it’s likely that many of these are common.

[div class=attrib]By Massimo Pigliucci at Rationally Speaking:[end-div]

Bronnie Ware is the author (a bit too much on the mystical-touchy-feely side for my taste) of the blog “Inspiration and Chai” (QED). But she has also worked for years in palliative care, thereby having the life-altering experience of sharing people’s last few weeks and listening to what they regretted the most about their now about to end lives. The result is this list of “top five” things people wished they had done differently:

1. I wish I’d had the courage to live a life true to myself, not the life others expected of me.
2. I wish I didn’t work so hard.
3. I wish I’d had the courage to express my feelings.
4. I wish I had stayed in touch with my friends.
5. I wish that I had let myself be happier.

This is, of course, anecdotal evidence from a single source, and as such it needs to be taken with a rather large grain of salt. But it is hard to read the list and not begin reflecting on your own life — even if you are (hopefully!) very far from the end.

Ware’s list, of course, is precisely why Socrates famously said that “the unexamined life is not worth living” (in Apology 38a, Plato’s rendition of Socrates’ speech at his trial), and why Aristotle considered the quest for eudaimonia (flourishing) a life-long commitment the success of which can be assessed only at the very end.

Let’s then briefly consider the list and see what we can learn from it. Beginning with the first entry, I’m not sure what it means for someone to be true to oneself, but I take it that the notion attempts to get at the fact that too many of us cave to societal forces early on and do not actually follow our aspirations. The practicalities of life have a way of imposing themselves on us, beginning with parental pressure to enter a remunerative career path and continuing with the fact that no matter what your vocation is you still have to somehow pay the bills and put dinner on the table every evening. And yet, you wouldn’t believe the number of people I’ve met in recent years who — about midway through their expected lifespan — suddenly decided that what they had been doing with their lives during the previous couple of decades was somewhat empty and needed to change. Almost without exception, these friends in their late ‘30s or early ‘40s contemplated — and many actually followed through — going back to (graduate) school and preparing for a new career in areas that they felt augmented the meaningfulness of their lives (often, but not always, that meant teaching). One could argue that such self-examination should have occurred much earlier, but we are often badly equipped, in terms of both education and life experience, to ask ourselves that sort of question when we are entering college. Better midway than at the end, though…

Atomic Poems: Oppenheimer, Ginsberg and Linkin Park

Sixty-six years ago on July 16, 1945 the world witnessed the first atomic bomb test. The bomb lit up the sky and scorched the earth at the White Sands Proving Ground over the Jornada del Muerto desert in New Mexico. The test of the implosion-design plutonium device was codenamed Trinity, part of the Manhattan Project.

The lead physicist was J. Robert Oppenheimer. He named the atomic test “Trinity” in a conflicted homage to John Donne’s poem, “Holy Sonnet XIV: Batter My Heart, Three-Personed God”:

[div class=attrib]By John Donne:[end-div]

Batter my heart, three-personed God; for you
As yet but knock, breathe, shine, and seek to mend;
That I may rise and stand, o’erthrow me, and bend
Your force to break, blow, burn, and make me new.
I, like an usurped town, to another due,
Labor to admit you, but O, to no end;
Reason, your viceroy in me, me should defend,
but is captived, and proves weak or untrue.
yet dearly I love you, and would be loved fain,
But am betrothed unto your enemy.
Divorce me, untie or break that knot again;
Take me to you, imprison me, for I,
Except you enthrall me, never shall be free,
Nor even chaste, except you ravish me.

Thirty-three years after the Trinity test on July 16, 1978, poet Allen Ginsberg published his nuclear protest poem “Plutonian Ode”, excerpted here:

. . .

Radioactive Nemesis were you there at the beginning 
        black dumb tongueless unsmelling blast of Disil-
        lusion?
I manifest your Baptismal Word after four billion years
I guess your birthday in Earthling Night, I salute your
        dreadful presence last majestic as the Gods,
Sabaot, Jehova, Astapheus, Adonaeus, Elohim, Iao, 
        Ialdabaoth, Aeon from Aeon born ignorant in an
        Abyss of Light,
Sophia's reflections glittering thoughtful galaxies, whirl-
        pools of starspume silver-thin as hairs of Einstein!
Father Whitman I celebrate a matter that renders Self
        oblivion!
Grand Subject that annihilates inky hands & pages'
        prayers, old orators' inspired Immortalities,
I begin your chant, openmouthed exhaling into spacious
        sky over silent mills at Hanford, Savannah River,
        Rocky Flats, Pantex, Burlington, Albuquerque
I yell thru Washington, South Carolina, Colorado, 
        Texas, Iowa, New Mexico,
Where nuclear reactors creat a new Thing under the 
        Sun, where Rockwell war-plants fabricate this death
        stuff trigger in nitrogen baths,
Hanger-Silas Mason assembles the terrified weapon
        secret by ten thousands, & where Manzano Moun-
        tain boasts to store
its dreadful decay through two hundred forty millenia
        while our Galaxy spirals around its nebulous core.
I enter your secret places with my mind, I speak with 
        your presence, I roar your Lion Roar with mortal
        mouth.
One microgram inspired to one lung, ten pounds of 
        heavy metal dust adrift slow motion over grey
        Alps
the breadth of the planet, how long before your radiance
        speeds blight and death to sentient beings?
Enter my body or not I carol my spirit inside you,
        Unnaproachable Weight,
O heavy heavy Element awakened I vocalize your con-
        sciousness to six worlds
I chant your absolute Vanity.  Yeah monster of Anger
        birthed in fear O most
Ignorant matter ever created unnatural to Earth! Delusion
        of metal empires!
Destroyer of lying Scientists! Devourer of covetous
        Generals, Incinerator of Armies & Melter of Wars!
Judgement of judgements, Divine Wind over vengeful 
        nations, Molester of Presidents, Death-Scandal of
        Capital politics! Ah civilizations stupidly indus-
        trious!
Canker-Hex on multitudes learned or illiterate! Manu-
        factured Spectre of human reason! O solidified
        imago of practicioner in Black Arts
I dare your reality, I challenge your very being! I 
        publish your cause and effect!
I turn the wheel of Mind on your three hundred tons!
        Your name enters mankind's ear! I embody your
        ultimate powers!
My oratory advances on your vaunted Mystery! This 
        breath dispels your braggart fears! I sing your 
        form at last
behind your concrete & iron walls inside your fortress
        of rubber & translucent silicon shields in filtered
        cabinets and baths of lathe oil,
My voice resounds through robot glove boxes & ignot 
        cans and echoes in electric vaults inert of atmo-
        sphere,
I enter with spirit out loud into your fuel rod drums
        underground on soundless thrones and beds of
        lead
O density! This weightless anthem trumpets transcendent 
        through hidden chambers and breaks through 
        iron doors into the Infernal Room!
Over your dreadful vibration this measured harmony        
        floats audible, these jubilant tones are honey and 
        milk and wine-sweet water
Poured on the stone black floor, these syllables are
        barley groats I scatter on the Reactor's core, 
I call your name with hollow vowels, I psalm your Fate
        close by, my breath near deathless ever at your
        side
to Spell your destiny, I set this verse prophetic on your
        mausoleum walls to seal you up Eternally with
        Diamond Truth!  O doomed Plutonium.

. . .

As noted in the Barnes and Noble Review:

Biographies of Oppenheimer portray him as a complex, contradicted man, and something of a poet himself. His love of poetry became well known when, in a 1965 interview, he famously claimed that his first reaction to the bomb test was a recollection of a line from the Bhagavad-Gita: “Now I am become death, the destroyer of worlds.”

Linkin Park’s  2010 concept album entitled “A Thousand Suns” captures Oppenheimer himself reciting these lines from Bhagavad-Gita scripture on recollecting Trinity atomic bomb test. He speaks on track 2, “Radiance”.

Tour de France and the Higgs Particle

Two exciting races tracked through Grenoble, France this passed week. First, the Tour de France held one of the definitive stages of the 2011 race in Grenoble, the individual time trial. Second, Grenoble hosted the European Physical Society conference on High-Energy Physics. Fans of professional cycling and high energy physics would not be disappointed.

In cycling, Cadel Evans set a blistering pace in his solo effort on stage 20 to ensure the Yellow Jersey and an overall win in this year’s Tour.

In the world of high energy physics, physicists from Fermilab and CERN presented updates on their competing searches to discover (or not) the Higgs boson. The two main experiments at Fermilab, CDF and DZero, are looking for traces of the Higgs particle in the debris of Tevatron collider’s proton-antiproton collisions. At CERN’s Large Hadron Collider scientists working at the two massive detectors, Atlas and CMS, are sifting through vast mountains of data accumulated from proton-proton collisions.

Both colliders have been smashing particles together in their ongoing quest to refine our understanding of the building blocks of matter, and to determine the existence of the Higgs particle. The Higgs is believed to convey mass to other particles, and remains one of the remaining undiscovered components of the Standard Model of physics.

The latest results presented in Grenoble show excess particle events, above a chance distribution, across the search range where the Higgs particle is predicted to be found. There is a surplus of unusual events at a mass of 140-145 GeV (gigaelectronvolts), which is at the low end of the range allowed for the particle. Tantalizingly, physicists’ theories predict that this is the most likely region where the Higgs is to be found.

[div class=attrib]Further details from Symmetry Breaking:[end-div]

Physicists could be on their way to discovering the Higgs boson, if it exists, by next year. Scientists in two experiments at the Large Hadron Collider pleasantly surprised attendees at the European Physical Society conference this afternoon by both showing small hints of what could be the prized particle in the same area.

“This is what we expect to find on the road to the Higgs,” said Gigi Rolandi, physics coordinator for the CMS experiment.

Both experiments found excesses in the 130-150 GeV mass region. But the excesses did not have enough statistical significance to count as evidence of the Higgs.

If the Higgs really is lurking in this region, it is still in reach of experiments at Fermilab’s Tevatron. Although the accelerator will shut down for good at the end of September, Fermilab’s CDF and DZero experiments will continue to collect data up until that point and to improve their analyses.

“This should give us the sensitivity to make a new statement about the 114-180 mass range,” said Rob Roser, CDF spokesperson. Read more about the differences between Higgs searches at the Tevatron and at the LHC here.

The CDF and DZero experiments announced expanded exclusions in the search for their specialty, the low-mass Higgs, this morning. On Wednesday, the two experiments will announce their combined Higgs results.

Scientists measure statistical significance in units called sigma, written as the Greek letter ?. These high-energy experiments usually require 3?  level of confidence, about 99.7 percent certainty, to claim they’ve seen evidence of something. They need 5? to claim a discovery. The ATLAS experiment reported excesses at confidence levels between 2 and 2.8?, and the CMS experiment found similar excesses at close to 3?.

After the two experiments combine their results — a mathematical process much more arduous than simple addition — they could find themselves on new ground. They hope to do this in the next few months, at the latest by the winter conferences, said Kyle Cranmer, an assistant professor at New York University who presented the results for the ATLAS collaboration.

“The fact that these two experiments with different issues, different approaches and different modeling found similar results leads you to believe it might not be just a fluke,” Cranmer said. “This is what it would look like if it were real.”

MondayPoem: August 6th

In keeping with our atoms and all things atomic theme this week, Monday’s poem is authored by Sankichi Toge, Japanese poet and peace activist.

Twenty-four-year-old Sankichi Toge was in Hiroshima when the atomic bomb was dropped on his city. Sankichi Toge began writing poems as a teenager; his first collection of poetry entitled, “Genbaku shishu (“Poems of the Atomic Bomb”) was published in 1951. He died at the age of 36 in Hiroshima.

His poem August 6th is named for the day in August 1945 on which the atomic bomb was dropped on Hiroshima.

August 6th

How could I ever forget that flash of light!
In a moment thirty thousand people ceased to be
The cries of fifty thousand killed
Through yellow smoke whirling into light
Buildings split, bridges collapsed
Crowded trams burnt as they rolled about
Hiroshima, all full of boundless heaps of embers
Soon after, skin dangling like rags
With hands on breasts
Treading upon the spilt brains
Wearing shreds of burnt cloth round their loins
There came numberless lines of the naked
all crying
Bodies on the parade ground, scattered like
jumbled stone images
Crowds in piles by the river banks
loaded upon rafts fastened to shore
Turned by and by into corpses
under the scorching sun
in the midst of flame
tossing against the evening sky
Round about the street where mother and
brother were trapped alive under the fallen house
The fire-flood shifted on
On beds of filth along the Armory floor
Heaps, God knew who they were….
Heaps of schoolgirls lying in refuse
Pot-bellied, one-eyed
with half their skin peeled off, bald
The sun shone, and nothing moved
but the buzzing flies in the metal basins
Reeking with stagnant odor
How can I forget that stillness
Prevailing over the city of three hundred thousand?
Amidst that calm
How can I forget the entreaties
Of the departed wife and child
Through their orbs of eyes
Cutting through our minds and souls?

Famous for the wrong book

[div class=attrib]From the Guardian:[end-div]

Why is it that the book for which an author is best known is rarely their best? If history is the final judge of literary achievement, why has a title like Louis de Bernières’ Captain Corelli’s Mandolin risen to the top, overshadowing his much better earlier novels such as Señor Vivo and the Coca Lord? It’s not, I hope, the simple snobbery of insisting that the most popular can’t be the finest. (After all, who would dispute that Middlemarch is George Eliot’s peak? … You would? Great, there’s a space for you in the comments below.)

If someone reads Kurt Vonnegut‘s most famous book, Slaughterhouse-Five, and doesn’t like it, I’ll want to shout to them, “But it’s rubbish! Cat’s Cradle is much better! That’s the one you want to read!” It’s not just me, I’m sure. Geoff Dyer takes the view that it is John Cheever’s journals, not his stories, which represent his “greatest achievement, his principal claim to literary survival”. Gabriel Josipovici says that it is not Kafka’s The Trial or “Metamorphosis” – not any of his novels or stories – which “form [his] most sustained meditation on life and death, good and evil, and the role of art”, but his aphorisms.

So here I am going to list a few instances of a writer being famous for the wrong book, and my suggestions for where their greatest achievement really lies. Below, you can make your own suggestions (someone, please tell me I’ve just been reading the wrong Peter Carey or Emily Brontë), or let me know just how misguided I am.

Joseph Heller
Catch-22 is too long, messy and takes 100 pages to get going. Heller’s second novel, Something Happened, took even longer to write and justified the time. From its opening line (“I get the willies when I see closed doors”), it is a supremely controlled and meticulous masterpiece, grounded in the horror of daily living. The first time I read it I was overwhelmed. The second time I thought it was hilarious. The third time – getting closer to the age of the horribly honest narrator Bob Slocum – it was terrifying. It’s the book that keeps on giving.

Learning to learn

[div class=attrib]By George Blecher for Eurozine:[end-div]

Before I learned how to learn, I was full of bullshit. I exaggerate. But like any bright student, I spent a lot of time faking it, pretending to know things about which I had only vague generalizations and a fund of catch-words. Why do bright students need to fake it? I guess because if they’re considered “bright”, they’re caught in a tautology: bright students are supposed to know, so if they risk not knowing, they must not be bright.

In any case, I faked it. I faked it so well that even my teachers were afraid to contradict me. I faked it so well that I convinced myself that I wasn’t faking it. In the darkest corners of the bright student’s mind, the borders between real and fake knowledge are blurred, and he puts so much effort into faking it that he may not even recognize when he actually knows something.

Above all, he dreads that his bluff will be called – that an honest soul will respect him enough to pick apart his faulty reasoning and superficial grasp of a subject, and expose him for the fraud he believes himself to be. So he lives in a state of constant fear: fear of being exposed, fear of not knowing, fear of appearing afraid. No wonder that Plato in The Republic cautions against teaching the “dialectic” to future Archons before the age of 30: he knew that instead of using it to pursue “Truth”, they’d wield it like a weapon to appear cleverer than their fellows.

Sometimes the worst actually happens. The bright student gets caught with his intellectual pants down. I remember taking an exam when I was 12, speeding through it with great cockiness until I realized that I’d left out a whole section. I did what the bright student usually does: I turned it back on the teacher, insisting that the question was misleading, and that I should be granted another half hour to fill in the missing part. (Probably Mr Lipkin just gave in because he knew what a pain in the ass the bright student can be!)

So then I was somewhere in my early 30s. No more teachers or parents to impress; no more exams to ace: just the day-to-day toiling in the trenches, trying to build a life.

NASA Retires Shuttle; France Telecom Guillotines Minitel

The lives of 2 technological marvels came to a close this week. First, NASA officially concluded the space shuttle program with the final flight of Atlantis.

Then, France Telecom announced the imminent demise of Minitel. Sacre Bleu! What next? Will the United Kingdom phase out afternoon tea and the Royal Family?

If you’re under 35 years of age, especially if you have never visited France, you may never have heard of Minitel. About ten years before the mainstream arrival of the World Wide Web and Mosaic, the first internet browser, there was Minitel. The Minitel network offered France Telecom subscribers a host of internet-like services such as email, white-pages, news and information services,  message boards, train reservations, airline schedules, stock quotes and online purchases. Users leased small, custom terminals for free that connected via telephone line. Think prehistoric internet services: no hyperlinks, no fancy search engines, no rich graphics and no multimedia — that was Minitel.

Though rudimentary, Minitel was clearly ahead of its time and garnered a wide and loyal following in France. France Telecom delivered millions of terminals for free to household and business telephone subscribers. By 2000, France Telecom estimates that almost 9 million terminals, covering 25 million people or over 41 percent of the French population, still had access to the Minitel network. Deploying the Minitel service allowed France Telecom to replace printed white-pages directories given to all its customers with a free, online Minitel version.

The Minitel equipment included a basic dumb terminal with a text based screen, keyboard and modem. The modem transmission speed was a rather slow 75 bits per second (upstream) and 1,200 bits per second (downstream). This compares with today’s basic broad speeds of 1 Mbit per second (upstream) and 4 Mbits per second (downstream).

In a bow to Minitel’s more attractive siblings, the internet and the World Wide Web, France Telecom finally plans to retire the service on the June 30, 2012.

First Ever Demonstration of Time Cloaking

[div class=attrib]From the Physics arXiv for Technology Review:[end-div]

Physicists have created a “hole in time” using the temporal equivalent of an invisibility cloak.

Invisibility cloaks are the result of physicists’ newfound ability to distort electromagnetic fields in extreme ways. The idea is steer light around a volume of space so that anything inside this region is essentially invisible.

The effect has generated huge interest. The first invisibility cloaks worked only at microwave frequencies but in only a few years, physicists have found ways to create cloaks that work for visible light, for sound and for ocean waves. They’ve even designed illusion cloaks that can make one object look like another.

Today, Moti Fridman and buddies, at Cornell University in Ithaca, go a step further. These guys have designed and built a cloak that hides events in time.

Time cloaking is possible because of a kind of duality between space and time in electromagnetic theory. In particular, the diffraction of a beam of light in space is mathematically equivalent to the temporal propagation of light through a dispersive medium. In other words, diffraction and dispersion are symmetric in spacetime.

That immediately leads to an interesting idea. Just as its easy to make a lens that focuses light in space using diffraction, so it is possible to use dispersion to make a lens that focuses in time.

Such a time-lens can be made using an electro-optic modulator, for example, and has a variety of familiar properties. “This time-lens can, for example, magnify or compress in time,” say Fridman and co.

This magnifying and compressing in time is important.

The trick to building a temporal cloak is to place two time-lenses in series and then send a beam of light through them. The first compresses the light in time while the second decompresses it again.

But this leaves a gap. For short period, there is a kind of hole in time in which any event is unrecorded.

So to an observer, the light coming out of the second time-lens appears undistorted, as if no event has occurred.

In effect, the space between the two lenses is a kind of spatio-temporal cloak that deletes changes that occur in short periods of time.

Why Does Time Fly?

[div class=attrib]From Scientific American:[end-div]

Everybody knows that the passage of time is not constant. Moments of terror or elation can stretch a clock tick to what seems like a life time. Yet, we do not know how the brain “constructs” the experience of subjective time. Would it not be important to know so we can find ways to make moments last, or pass by, more quickly?

A recent study by van Wassenhove and colleagues is beginning to shed some light on this problem. This group used a simple experimental set up to measure the “subjective” experience of time. They found that people accurately judge whether a dot appears on the screen for shorter, longer or the same amount of time as another dot. However, when the dot increases in size so as to appear to be moving toward the individual — i.e. the dot is “looming” — something strange happens. People overestimate the time that the dot lasted on the screen.  This overestimation does not happen when the dot seems to move away.  Thus, the overestimation is not simply a function of motion. Van Wassenhove and colleagues conducted this experiment during functional magnetic resonance imaging, which enabled them to examine how the brain reacted differently to looming and receding.

The brain imaging data revealed two main findings. First, structures in the middle of the brain were more active during the looming condition. These brain areas are also known to activate in experiments that involve the comparison of self-judgments to the judgments of others, or when an experimenter does not tell the subject what to do. In both cases, the prevailing idea is that the brain is busy wondering about itself, its ongoing plans and activities, and relating oneself to the rest of the world.

Book Review: Linchpin. Seth Godin

Phew! Another heartfelt call to action from business blogger Seth Godin to become indispensable.

Author, public speaker, orthogonal thinker and internet marketing maven, Seth Godin makes a compelling case to the artist within us all to get off our backsides, ignore the risk averse “lizard brain” as he puts it, get creative, and give the gift of art. After all there is no way to win the “race to the bottom” wrought by commoditization of both product and labor.

Bear in mind, Godin uses “art” in its most widely used sense, not merely a canvas or a sculpture. Here, art is anything that its maker so creates; it may be a service just as well as an object. Importantly also, to be art it has to be given with the correct intent — as a gift (a transcendent, unexpected act that surpasses expectation).

Critics maintain that his latest bestseller is short on specifics, but indeed it should be. After all if the process of creating art could be decomposed to an instruction manual it wouldn’t deliver art, it would deliver a Big Mac. So while, we do not get a “7 point plan” that leads to creative nirvana, Godin does a good job through his tireless combination of anecdote, repetition, historical analysis and social science at convincing the “anonymous cogs in the machine” to think and act more like the insightful, innovators that we can all become.

Godin rightly believes that the new world of work is rife with opportunity to add value through creativity, human connection and generosity, and this is the area where the indispensable artist gets to create his or her art, and to become a linchpin in the process. Godin’s linchpin is a rule-breaker, not a follower; a map-maker, not an order taker; a doer not a whiner.

In reading Linchpin we are reminded of the other side of the economy, in which we all unfortunately participate as well, the domain of commoditization, homogeneity and anonymity. This is the domain that artists so their utmost to avoid, and better still, subvert. Of course, this economy provides a benefit too – lower price. However, a “Volkswagen-sized jar of pickles for $3” can only go so far. Commoditization undermines our very social fabric: it undermines our desire for uniqueness and special connection in a service or product that we purchase; it removes our dignity and respect when we allow ourselves to become a disposable part, a human cog, in the job machine. So, jettison the bland, the average, and the subservient, learn to take risk, face fear and become an indispensable, passionate, discerning artist – one who creates and one who gives.

Lucian Freud dies aged 88

[div class=attrib]From the Guardian:[end-div]

Lucian Freud, widely acknowledged as one of the greatest, most influential and yet most controversial British painters of his era, has died at his London home.

News of his death, at the age of 88, was released by his New York art dealer, William Acquavella. The realist painter, who was a grandson of the psychoanalyst Sigmund Freud, had watched his works soar in value over recent years and, in 2008, his portrayal of a large, naked woman on a couch – Benefit Supervisor Sleeping – sold at auction for £2.6m, a record price for the work of a living artist.

Born in Berlin, Freud came to Britain in 1933 with his family when he was 10 years old and developed his passion for drawing. After studying at art school, he had a self-portrait accepted for Horizon magazine and, by the age of 21, his talent had been recognised in a solo show. He returned to Britain after the war years to teach at the Slade School of Art in London.

Over a career that spanned 50 years, Freud became famous for his intense and unsettling nude portraits. A naturalised British subject, he spent most of his working life in London and was frequently seen at the most salubrious bars and restaurants, often in the company of beautiful young women such as Kate Moss, who he once painted. A tweet from the writer Polly Samson last night reported that Freud’s regular table in The Wolseley restaurant was laid with a black tablecloth and a single candle in his honour.

The director of the Tate gallery, Nicholas Serota, said last night: “The vitality of [Freud’s] nudes, the intensity of the still life paintings and the presence of his portraits of family and friends guarantee Lucian Freud a unique place in the pantheon of late 20th century art.

Face (Recognition) Time

If you’ve traveled or lived in the UK then you may well have been filmed and recorded by one of Britain’s 4.2 million security cameras (and that’s the count as of 2009).  That’s one per every 14 people.

While it’s encouraging that the United States and other nations have not followed a similar dubious path, there are reports that facial recognition systems will soon be mobile, and in the hands of police departments across the nation.

[div class=attrib]From Slate:[end-div]

According to the Wall Street Journal, police departments across the nation will soon adopt handheld facial-recognition systems that will let them identify people with a snapshot. These new capabilities are made possible by BI2 Technologies, a Massachusetts company that has developed a small device that attaches to officers’ iPhones. The police departments who spoke to the Journal said they plan to use the device only when officers suspect criminal activity and have no other way to identify a person—for instance, when they stop a driver who isn’t carrying her license. Law enforcement officials also seemed wary about civil liberties concerns. Is snapping someone’s photo from five feet away considered a search? Courts haven’t decided the issue, but sheriffs who spoke to the paper say they plan to exercise caution.

Don’t believe it. Soon, face recognition will be ubiquitous. While the police may promise to tread lightly, the technology is likely to become so good, so quickly that officers will find themselves reaching for their cameras in all kinds of situations. The police will still likely use traditional ID technologies like fingerprinting—or even iris scanning—as these are generally more accurate than face-scanning, but face-scanning has an obvious advantage over fingerprints: It works from far away. Bunch of guys loitering on the corner? Scantily clad woman hanging around that run-down motel? Two dudes who look like they’re smoking a funny-looking cigarette? Why not snap them all just to make sure they’re on the up-and-up?

Sure, this isn’t a new worry. Early in 2001, police scanned the faces of people going to the Super Bowl, and officials rolled out the technology at Logan Airport in Boston after 9/11. Those efforts raised a stink, and the authorities decided to pull back. But society has changed profoundly in the last decade, and face recognition is now set to go mainstream. What’s more, the police may be the least of your worries. In the coming years—if not months—we’ll see a slew of apps that allow your friends and neighbors to snap your face and get your name and other information you’ve put online. This isn’t a theoretical worry; the technology exists, now, to do this sort of thing crudely, and the only thing stopping companies from deploying it widely is a fear of public outcry. That fear won’t last long. Face recognition for everyone is coming. Get used to it.

Saluting a Fantastic Machine and Courageous Astronauts

[div class=attrib]From the New York Times:[end-div]

The last space shuttle flight rolled to a stop just before 6 a.m. on Thursday, closing an era of the nation’s space program.

“Mission complete, Houston,” said Capt. Christopher J. Ferguson of the Navy, commander of the shuttle Atlantis for the last flight. “After serving the world for over 30 years, the space shuttle has earned its place in history, and it’s come to a final stop.”

It was the 19th night landing at the Kennedy Space Center in Florida to end the 135th space shuttle mission. For Atlantis, the final tally of its 26-year career is 33 missions, accumulating just short of 126 million miles during 307 days in space, circumnavigating the Earth 4,848 times.

A permanent marker will be placed on the runway to indicate the final resting spot of the space shuttle program.

The last day in space went smoothly. Late on Wednesday night, the crew awoke to the Kate Smith version of “God Bless America.” With no weather or technical concerns, the crew closed the payload doors at 2:09 a.m. on Thursday.

At 4:13 a.m., Barry E. Wilmore, an astronaut at mission control in Houston, told the Atlantis crew, “Everything is looking fantastic, there you are go for the deorbit burn, and you can maneuver on time.”

“That’s great, Butch,” replied Captain Ferguson. “Go on the deorbit maneuver, on time.”

Book Review: America Pacifica

Classic dystopian novels from the likes of Aldous Huxley, George Orwell, Philip K. Dick, Ursula K. Le Guin, and Margaret Atwood appeal for their fantastic narrative journeys. More so they resonate for it often seems that contemporary society is precariously close to this fictional chaos, dysfunction and destruction; one small step in the wrong direction and over the precipice we go. America Pacifica continues this tradition.

[div class=attrib]From The Barnes & Noble Review:[end-div]

Anna North is both a graduate of the Iowa Writers’ Work Shop and a writer for the feminist Web site Jezebel. It’s no surprise, then, that her debut novel, America Pacifica, is overflowing with big ideas about revolution, ecology, feminism, class, and poverty. But by the end of page one, when a teenage daughter, Darcy, watches her beloved mother, Sarah, emerge from a communal bathroom down the hall carrying “their” toothbrush, one also knows that this novel, like, say, the dystopic fiction of Margaret Atwood or Ursula K. Le Guin, aims not only to transmit those ideas in the form of an invented narrative, but also to give them the animating, detailed, and less predictable life of literature.

The “America Pacifica” of the title is an unnamed island upon which a generation of North American refugees have attempted to create a simulacra of their old home–complete with cities named Manhattanville and Little Los Angeles–after an environmental calamity rendered “the mainland” too frigid for human life. Daniel, a mainland scientist, argued that the humans should adapt themselves to the changing climate, while a man named Tyson insisted that they look for a warmer climate and use technology and dirty industrial processes to continue human life as it was once lived. The island’s population is comprised entirely of those who took Tyson’s side of the argument.

But this haven can only sustain enough luxuries for a tiny few. Every aspect of island life is governed by a brutal caste system which divides people into rigid hierarchies based on the order in which they and their families arrived by boat. The rich eat strawberries and fresh tomatoes, wear real fiber, and live in air-conditioned apartments. The poor subsist on meat products fabricated from jellyfish and seaweed, wear synthetic SeaFiber clothing, and dream of somehow getting into college (which isn’t open to them) so they can afford an apartment with their own bathroom and shower.

Equation: How GPS Bends Time

[div class=attrib]From Wired:[end-div]

Einstein knew what he was talking about with that relativity stuff. For proof, just look at your GPS. The global positioning system relies on 24 satellites that transmit time-stamped information on where they are. Your GPS unit registers the exact time at which it receives that information from each satellite and then calculates how long it took for the individual signals to arrive. By multiplying the elapsed time by the speed of light, it can figure out how far it is from each satellite, compare those distances, and calculate its own position.

For accuracy to within a few meters, the satellites’ atomic clocks have to be extremely precise—plus or minus 10 nanoseconds. Here’s where things get weird: Those amazingly accurate clocks never seem to run quite right. One second as measured on the satellite never matches a second as measured on Earth—just as Einstein predicted.

According to Einstein’s special theory of relativity, a clock that’s traveling fast will appear to run slowly from the perspective of someone standing still. Satellites move at about 9,000 mph—enough to make their onboard clocks slow down by 8 microseconds per day from the perspective of a GPS gadget and totally screw up the location data. To counter this effect, the GPS system adjusts the time it gets from the satellites by using the equation here. (Don’t even get us started on the impact of general relativity.)

How the Great White Egret Spurred Bird Conservation

The infamous Dead Parrot Sketch from Monty Python’s Flying Circus continues to resonate several generations removed from its creators. One of the most treasured exchanges, between a shady pet shop owner and prospective customer included two immortal comedic words, “Beautiful plumage”, followed by the equally impressive retort, “The plumage don’t enter into it. It’s stone dead.”

Though utterly silly this conversation does point towards a deeper and very ironic truth: that humans so eager to express their status among their peers do this by exploiting another species. Thus, the stunning white plumage of the Great White Egret proved to be its undoing, almost. So utterly sought after were the egrets’ feathers that both males and females were hunted close to extinction. And, in a final ironic twist, the near extinction of these great birds inspired the Audubon campaigns and drove legislation to curb the era of fancy feathers.

[div class=attrib]More courtesy of the Smithsonian[end-div]

I’m not the only one who has been dazzled by the egret’s feathers, though. At the turn of the 20th century, these feathers were a huge hit in the fashion world, to the detriment of the species, as Thor Hanson explains in his new book Feathers: The Evolution of a Natural Miracle:

One particular group of birds suffered near extermination at the hands of feather hunters, and their plight helped awaken a conservation ethic that still resonates in the modern environmental movement. With striking white plumes and crowded, conspicuous nesting colonies, Great Egrets and Snowy Egrets faced an unfortunate double jeopardy: their feathers fetched a high price, and their breeding habits made them an easy mark. To make matters worse, both sexes bore the fancy plumage, so hunters didn’t just target the males; they decimated entire rookeries. At the peak of the trade, an ounce of egret plume fetched the modern equivalent of two thousand dollars, and successful hunters could net a cool hundred grand in a single season. But every ounce of breeding plumes represented six dead adults, and each slain pair left behind three to five starving nestlings. Millions of birds died, and by the turn of the century this once common species survived only in the deep Everglades and other remote wetlands.

This slaughter inspired Audubon members to campaign for environmental protections and bird preservation, at the state, national and international levels.

The Pervasive Threat of Conformity: Peer Pressure Is Here to Stay

[div class=attrib]From BigThink:[end-div]

Today, I’d like to revisit one of the most well-known experiments in social psychology: Solomon Asch’s lines study. Let’s look once more at his striking findings on the power of group conformity and consider what they mean now, more than 50 years later, in a world that is much changed from Asch’s 1950s America.

How long are these lines? I don’t know until you tell me.

In the 1950s, Solomon Asch conducted a series of studies to examine the effects of peer pressure, in as clear-cut a setting as possible: visual perception. The idea was to see if, when presented with lines of differing lengths and asked questions about the lines (Which was the longest? Which corresponded to a reference line of a certain length?), participants would answer with the choice that was obviously correct – or would fall sway to the pressure of a group that gave an incorrect response. Here is a sample stimulus from one of the studies:

Which line matches the reference line? It seems obvious, no? Now, imagine that you were in a group with six other people – and they all said that it was, in fact, Line B.  Now, you would have no idea that you were the only actual participant and that the group was carefully arranged with confederates, who were instructed to give that answer and were seated in such a way that they would answer before you. You’d think that they, like you, were participants in the study – and that they all gave what appeared to you to be a patently wrong answer. Would you call their bluff and say, no, the answer is clearly Line A? Are you all blind? Or, would you start to question your own judgment? Maybe it really is Line B. Maybe I’m just not seeing things correctly. How could everyone else be wrong and I be the only person who is right?

We don’t like to be the lone voice of dissent

While we’d all like to imagine that we fall into the second camp, statistically speaking, we are three times more likely to be in the first: over 75% of Asch’s subjects (and far more in the actual condition given above) gave the wrong answer, going along with the group opinion.

Richard Feynman on the Ascendant

Genius – The Life and Science of Richard Feynman by James Gleick was a good first course for those fascinated by Richard Feynman’s significant contributions to physics, cosmology (and percussion).

Now, eight years later come two more biographies that observe Richard Feynman from very different perspectives, reviewed in the New York Review of Books. The first, Lawrence Krauss’s book, Quantum Man is the weighty main course; the second, by Jim Ottaviani and artist Leland Myrick, is a graphic-book (as in comic) biography, and delicious dessert.

In his review — The ‘Dramatic Picture’ of Richard Feynman — Freeman Dyson rightly posits that Richard Feynman’s star may now, or soon, be in the same exalted sphere as Einstein and Hawking. Though, type “Richard” in Google search and wait for its predictive text to fill in the rest and you’ll find that Richard Nixon, Richard Dawkins and Richard Branson rank higher than this giant of physics.

[div class=attrib]Freeman Dyson for the New York Review of Books:[end-div]

In the last hundred years, since radio and television created the modern worldwide mass-market entertainment industry, there have been two scientific superstars, Albert Einstein and Stephen Hawking. Lesser lights such as Carl Sagan and Neil Tyson and Richard Dawkins have a big public following, but they are not in the same class as Einstein and Hawking. Sagan, Tyson, and Dawkins have fans who understand their message and are excited by their science. Einstein and Hawking have fans who understand almost nothing about science and are excited by their personalities.

On the whole, the public shows good taste in its choice of idols. Einstein and Hawking earned their status as superstars, not only by their scientific discoveries but by their outstanding human qualities. Both of them fit easily into the role of icon, responding to public adoration with modesty and good humor and with provocative statements calculated to command attention. Both of them devoted their lives to an uncompromising struggle to penetrate the deepest mysteries of nature, and both still had time left over to care about the practical worries of ordinary people. The public rightly judged them to be genuine heroes, friends of humanity as well as scientific wizards.

Two new books now raise the question of whether Richard Feynman is rising to the status of superstar. The two books are very different in style and in substance. Lawrence Krauss’s book, Quantum Man, is a narrative of Feynman’s life as a scientist, skipping lightly over the personal adventures that have been emphasized in earlier biographies. Krauss succeeds in explaining in nontechnical language the essential core of Feynman’s thinking.

… The other book, by writer Jim Ottaviani and artist Leland Myrick, is very different. It is a comic-book biography of Feynman, containing 266 pages of pictures of Feynman and his legendary adventures. In every picture, bubbles of text record Feynman’s comments, mostly taken from stories that he and others had told and published in earlier books.

The Worst of States, the Best of States

Following on from our recent article showing the best of these United States, it’s time to look at the worst.

[div class=attrib]From Frank Jacobs / BigThink:[end-div]

The United States of Shame again gets most of its data from health stats, detailing the deplorable firsts of 14 states (9). Eight states get worst marks for crime, from white-collar to violent (10), while four lead in road accidents (11). Six can be classed as economic worst cases (12), five as moral nadirs (13), two as environmental basket cases (14). In a category of one are states like Ohio (‘Nerdiest’), Maine (‘Dumbest’) and North Dakota (‘Ugliest’).

All claims are neatly backed up by references, some of them to reliable statistics, others to less scientific straw polls. In at least one case, to paraphrase Dickens, the best of stats really is the worst of stats. Ohio’s ‘shameful’ status as nerdiest state is based on its top ranking in library visits. Yet on the ‘awesome’ map, Ohio is listed as the state with… most library visits.

Juxtaposing each state’s best and worst leads to interesting statistical pairings. But with data as haphazardly corralled together as this, causal linkage should be avoided. Otherwise it could be concluded that:

A higher degree of equality leads to an increase in suicides (Alaska);
Sunny weather induces alcoholism (Arizona);
Breastfeeding raises the risk of homelessness (Oregon).
Yet in some cases, some kind of link can be inferred. New Yorkers use more public transit than other Americans, but are also stuck with the longest commutes.

MondayPoem: The Enigma of the Infinitesimal

Monday’s poem comes from Mark Strand over a Slate. Strand was United States Poet Laureate during 1990-91. He won the 1999 Pulitzer Prize for Poetry for “Blizzard of One”.

The poem is austere and spare yet is simply evocative. Is Strand conjuring the spirits and ghosts of our imagination? Perhaps not. These “[l]overs of the in-between” are more likely to be the creative misfits who shy away from attention and who don’t conform to our societal norms. Bloggers perhaps?

[div class=attrib]By Mark Strand for Slate:[end-div]

You’ve seen them at dusk, walking along the shore, seen them standing in doorways, leaning from windows, or straddling the slow moving edge of a shadow. Lovers of the in-between, they are neither here nor there, neither in nor out. Poor souls, they are driven to experience the impossible. Even at night, they lie in bed with one eye closed and the other open, hoping to catch the last second of consciousness and the first of sleep, to inhabit that no man’s land, that beautiful place, to behold as only a god might, the luminous conjunction of nothing and all.

Book Review: The First Detective

A new book by James Morton examines the life and times of cross-dressing burglar, prison-escapee and snitch turned super-detective Eugène-François Vidocq.

[div class=attrib]From The Barnes & Noble Review:[end-div]

The daring costumed escapes and bedsheet-rope prison breaks of the old romances weren’t merely creaky plot devices; they were also the objective correlatives of the lost politics of early modern Europe. Not yet susceptible to legislative amelioration, rules and customs that seemed both indefensible and unassailable had to be vaulted over like collapsing bridges or tunneled under like manor walls. Not only fictional musketeers but such illustrious figures as the young Casanova and the philosopher Jean-Jacques Rousseau spent their early years making narrow escapes from overlapping orthodoxies, swimming moats to marriages of convenience and digging their way  out of prisons of privilege by dressing in drag or posing as noblemen’s sons. If one ran afoul of the local clergy or some aristocratic cuckold, there were always new bishops and magistrates to charm in the next diocese or département.

In 1775–roughly a generation after the exploits of Rousseau and Casanova–a prosperous baker’s son named Eugène-François Vidocq was born in Arras, in northern France. Indolent and adventuresome, he embarked upon a career that in its early phase looked even more hapless and disastrous than those of his illustrious forebears. An indifferent soldier in the chaotic, bloody interregnum of revolutionary France, Vidocq quickly fell into petty crime (at one point, he assumed the name Rousseau for a time as an alias and nom de guerre). A hapless housebreaker and a credulous co-conspirator, his criminal misadventures were equaled only by his skill escaping from the dungeons and bagnes that passed for a penal system in the pre-Napoleonic era.

By 1809, his canniness as an informer landed him a job with the police; with his old criminal comrades as willing foot soldiers, Vidocq organized a brigade de sûreté, a unit of plainclothes police, which in 1813 Napoleon made an official organ of state security. Throughout his subsequent career he would lay much of the foundation of modern policing, and may be considered a forebear not only to the Dupins and the Holmes of modern detective literature but of swashbuckling, above-the-law policemen like Eliot Ness and J. Edgar Hoover as well.

When the multiverse and many-worlds collide

[div class=attrib]From the New Scientist:[end-div]

TWO of the strangest ideas in modern physics – that the cosmos constantly splits into parallel universes in which every conceivable outcome of every event happens, and the notion that our universe is part of a larger multiverse – have been unified into a single theory. This solves a bizarre but fundamental problem in cosmology and has set physics circles buzzing with excitement, as well as some bewilderment.

The problem is the observability of our universe. While most of us simply take it for granted that we should be able to observe our universe, it is a different story for cosmologists. When they apply quantum mechanics – which successfully describes the behaviour of very small objects like atoms – to the entire cosmos, the equations imply that it must exist in many different states simultaneously, a phenomenon called a superposition. Yet that is clearly not what we observe.

Cosmologists reconcile this seeming contradiction by assuming that the superposition eventually “collapses” to a single state. But they tend to ignore the problem of how or why such a collapse might occur, says cosmologist Raphael Bousso at the University of California, Berkeley. “We’ve no right to assume that it collapses. We’ve been lying to ourselves about this,” he says.

In an attempt to find a more satisfying way to explain the universe’s observability, Bousso, together with Leonard Susskind at Stanford University in California, turned to the work of physicists who have puzzled over the same problem but on a much smaller scale: why tiny objects such as electrons and photons exist in a superposition of states but larger objects like footballs and planets apparently do not.

This problem is captured in the famous thought experiment of Schrödinger’s cat. This unhappy feline is inside a sealed box containing a vial of poison that will break open when a radioactive atom decays. Being a quantum object, the atom exists in a superposition of states – so it has both decayed and not decayed at the same time. This implies that the vial must be in a superposition of states too – both broken and unbroken. And if that’s the case, then the cat must be both dead and alive as well.

Dark energy spotted in the cosmic microwave background

[div class=attrib]From Institute of Physics:[end-div]

Astronomers studying the cosmic microwave background (CMB) have uncovered new direct evidence for dark energy – the mysterious substance that appears to be accelerating the expansion of the universe. Their findings could also help map the structure of dark matter on the universe’s largest length scales.

The CMB is the faint afterglow of the universe’s birth in the Big Bang. Around 400,000 years after its creation, the universe had cooled sufficiently to allow electrons to bind to atomic nuclei. This “recombination” set the CMB radiation free from the dense fog of plasma that was containing it. Space telescopes such as WMAP and Planck have charted the CMB and found its presence in all parts of the sky, with a temperature of 2.7 K. However, measurements also show tiny fluctuations in this temperature on the scale of one part in a million. These fluctuations follow a Gaussian distribution.

In the first of two papers, a team of astronomers including Sudeep Das at the University of California, Berkeley, has uncovered fluctuations in the CMB that deviate from this Gaussian distribution. The deviations, observed with the Atacama Cosmology Telescope in Chile, are caused by interactions with large-scale structures in the universe, such as galaxy clusters. “On average, a CMB photon will have encountered around 50 large-scale structures before it reaches our telescope,” Das told physicsworld.com. “The gravitational influence of these structures, which are dominated by massive clumps of dark matter, will each deflect the path of the photon,” he adds. This process, called “lensing”, eventually adds up to a total deflection of around 3 arc minutes – one-20th of a degree.

Dark energy versus structure

In the second paper Das, along with Blake Sherwin of Princeton University and Joanna Dunkley of Oxford University, looks at how lensing could reveal dark energy. Dark energy acts to counter the emergence of structures within the universe. A universe with no dark energy would have a lot of structure. As a result, the CMB photons would undergo greater lensing and the fluctuations would deviate more from the original Gaussian distribution.

Green Bootleggers and Baptists

[div class=attrib]Bjørn Lomborg for Project Syndicate:[end-div]

In May, the United Nations’ International Panel on Climate Change made media waves with a new report on renewable energy. As in the past, the IPCC first issued a short summary; only later would it reveal all of the data. So it was left up to the IPCC’s spin-doctors to present the take-home message for journalists.

The first line of the IPCC’s press release declared, “Close to 80% of the world‘s energy supply could be met by renewables by mid-century if backed by the right enabling public policies.” That story was repeated by media organizations worldwide.

Last month, the IPCC released the full report, together with the data behind this startlingly optimistic claim. Only then did it emerge that it was based solely on the most optimistic of 164 modeling scenarios that researchers investigated. And this single scenario stemmed from a single study that was traced back to a report by the environmental organization Greenpeace. The author of that report – a Greenpeace staff member – was one of the IPCC’s lead authors.

The claim rested on the assumption of a large reduction in global energy use. Given the number of people climbing out of poverty in China and India, that is a deeply implausible scenario.

When the IPCC first made the claim, global-warming activists and renewable-energy companies cheered. “The report clearly demonstrates that renewable technologies could supply the world with more energy than it would ever need,” boasted Steve Sawyer, Secretary-General of the Global Wind Energy Council.

This sort of behavior – with activists and big energy companies uniting to applaud anything that suggests a need for increased subsidies to alternative energy – was famously captured by the so-called “bootleggers and Baptists” theory of politics.

The theory grew out of the experience of the southern United States, where many jurisdictions required stores to close on Sunday, thus preventing the sale of alcohol. The regulation was supported by religious groups for moral reasons, but also by bootleggers, because they had the market to themselves on Sundays. Politicians would adopt the Baptists’ pious rhetoric, while quietly taking campaign contributions from the criminals.

Of course, today’s climate-change “bootleggers” are not engaged in any illegal behavior. But the self-interest of energy companies, biofuel producers, insurance firms, lobbyists, and others in supporting “green” policies is a point that is often missed.

Indeed, the “bootleggers and Baptists” theory helps to account for other developments in global warming policy over the past decade or so. For example, the Kyoto Protocol would have cost trillions of dollars, but would have achieved a practically indiscernible difference in stemming the rise in global temperature. Yet activists claimed that there was a moral obligation to cut carbon-dioxide emissions, and were cheered on by businesses that stood to gain.
