Watcher of the Skies

Manjit Kumar in The Telegraph:

Galileo-m_1733576f It is a little known fact that in 1532 Copernicus’s sun-centred solar system was presented to an audience in the Vatican. Given the storm that was to come, it is barely believable that the then pope, Leo X, afterwards sent a note of encouragement to Copernicus as the Polish priest laboured to finish his book. On the Revolutions of the Heavenly Spheres was published in 1543 and Copernicus, so the story goes, held the first copy to come off the press just hours before he died. As long as his heliocentric model was presented as hypothetical, the Vatican was unconcerned by Copernicanism. One man changed all that.Born in February 1564, Galileo Galilei initially set out to be a doctor before switching to mathematics – much to the displeasure of his father. It is unlikely that, according to the legend, he ever dropped balls from the leaning tower of Pisa as he investigated the motion of falling bodies and discovered that all objects fall at the same rate, contradicting what everybody believed since Aristotle.

When, in 1609, he learnt of the invention of the telescope by a Dutch spectacle maker, Galileo quickly constructed his own. Within a matter of months he had transformed it from a toy into an instrument of scientific discovery and he found that the Milky Way was not a streak across the sky but a multitude of stars; that the Moon had mountains and valleys; and he observed the phases of Venus and the spots on the Sun. 'For Galileo, seeing was believing,’ says the historian David Wootton. Yet he argues persuasively in this well researched, intellectual biography that Galileo was a Copernican long before his discovery of the moons of Jupiter proved that not all heavenly bodies revolved around the Earth. In March 1610, Galileo published his discoveries in the aptly titled book, The Starry Messenger. All 550 copies were sold within a week and soon the 46 year-old was Europe’s most celebrated natural philosopher.

buffalo, the hallelujah, and a dog

Tumblr_l6ma42dhec1qabu3po1_500

I have never thought of Buffalo as a city of rebirth. It’s too cold there. And the city has been dying for more than a generation. All of upstate New York is like that, the creeping death and a winter that pounds the graveyards into tundra for much of the year. I have a healthy respect for Buffalo, for this very reason. But only a madman would go there to be reborn. LaDainian Tramayne Tomlinson is just such a madman. He was supposed to fade away, to be hidden deep in the roster of some team needing depth at running back after the San Diego Chargers traded him away at the end of last season. His motor had run down, his legs couldn’t do it anymore. Nine seasons is a long time for a workhorse. The body revolts. The ligaments, sinews, and tendons start to scream inside their fleshy shell all year long. And so, Tomlinson was meant to go out to pasture like all the rest, collecting a few more paychecks from a league whose memory is necessarily short.

The Elections: How Bad for Democrats?

Tomasky_1-102810_jpg_230x420_q85 Michael Tomasky in the NYRB:

My own answer to the question of how things got this bad has less to do with whether Obama should have been more liberal or more centrist than with his and his party’s apparent inability, or perhaps refusal, to offer broad and convincing arguments about their central beliefs that counter those of the Republicans. This problem goes back to the Reagan years. It is a failure that many Democrats and liberals hoped Obama could change—something he seemed capable of changing during the campaign but has addressed rather poorly once in office.

In American politics, Republicans routinely speak in broad themes and tend to blur the details, while Democrats typically ignore broad themes and focus on details. Republicans, for example, speak constantly of “liberty” and “freedom” and couch practically all their initiatives—tax cuts, deregulation, and so forth—within these large categories. Democrats, on the other hand, talk more about specific programs and policies and steer clear of big themes. There is a reason for this: Republican themes, like “liberty,” are popular, while Republican policies often are not; and Democratic themes (“community,” “compassion,” “justice”) are less popular, while many specific Democratic programs—Social Security, Medicare, even (in many polls) putting a price on carbon emissions—have majority support. This is why, when all else fails, Democrats try to scare people about the threat to Social Security if the GOP takes over, as indeed they are doing right now.

What Democrats have typically not done well since Reagan’s time is connect their policies to their larger beliefs. In fact they have usually tried to hide those beliefs, or change the conversation when the subject arose. The result has been that for many years Republicans have been able to present their philosophy as somehow truly “American,” while attacking the Democratic belief system as contrary to American values. “Putting us on the road to European-style socialism,” for example, is a rhetorical line of attack that long predates Obama’s ascendance—it was employed against the Clintons’ health care plan as well.

Kashmir’s Forever War

1283783497633.jpeg Basharat Peer in Granta:

Srinagar used to be a city of elegant latticed houses, mosques and temples on the banks of the river. Srinagar was people strolling on the wooden bridges and wandering into old bazaars or stepping with a prayer into a Sufi shrine with papier-mâché interiors. Now it is a city of bunkers, a medieval city dying in a modern war. One of the most prominent landmarks of war is the sprawling Martyrs’ Graveyard in north-western Srinagar; several hundred Kashmiris killed in the early days of the conflict are buried here. Among them is a well-known politician and head cleric of Srinagar grand mosque, Moulvi Mohammed Farooq, who was assassinated by pro-Pakistan militants on 21 May 1990. More than sixty mourners were killed when Indian paramilitaries fired upon his funeral procession. The cleric’s eighteen-year-old son, Omar Farooq, left school to inherit his father’s mantle. He is now one of the best-known Kashmiri separatists, heading the Hurriyat (Freedom) Conference coalition.

A few days before the twentieth anniversary of his father’s assassination, I walked past the Martyrs’ Graveyard to an old wooden mosque nearby, where Farooq was holding a meeting with his supporters. In an elegant brown lambskin cap and delicately embroidered beige gown, he deftly mixed his roles as a modern politician and the head cleric in Kashmir’s Sufi tradition, leading his followers in a sing-song voice humming Kashmiri and Persian devotional songs and then moving effortlessly to the question of Kashmiri politics. He spoke of the memory of the thousands who had died in the battles for Kashmir, including his father. He spoke of preventing further deaths. And then the old Kashmiri slogans for independence followed. ‘Kashmir is for Kashmiris!’ Farooq shouted. ‘We will decide our destiny!’ the people replied. He was about to lead a march through the city. Outside, excited young supporters were revving up their motorbikes and raising flags on cars.

Over the years, Farooq has engaged with both India and Pakistan and sought to rally the Kashmiris towards a peaceful agreement, often at a high personal price. In 2004, after failed peace talks with India, pro-Pakistan militants assassinated his uncle.

Meera Syal: My family values

From The Guardian:

Meera-Syal-006 We lived in Essington, a mining village close to Walsall, in the West Midlands. It was a very rural, working-class upbringing and one of my earliest memories is walking through a cornfield with my dad. My early years were a riot of earthy smells, outside loos, fun in fields and windy bus stops. And lots and lots of fresh air and freedom.

Inside our Punjabi household the atmosphere was one of familiarity and solidity, but outside the house things sometimes felt threatening. I have vivid memories of my parents and all their friends talking about a certain speech that Enoch Powell made. I always thought that the reason there were packed suitcases on top of every wardrobe was that we might have to leave the country in the middle of the night because of Enoch Powell. It was only years later that I realised that everybody's families had suitcases on top of the wardrobe.

Punjabis are the cockneys of India. They are party people – gregarious, outgoing, very entrepreneurial, sharp-witted, loud, meat-eaters. Back in the Punjab, they are basically earthy, rural workers. And that was very much the atmosphere when we had friends around. It was incredibly noisy, loads of music, lots of loud voices and drinking, and I thought that was normal until I went to other people's houses and I was shocked to discover that sometimes people's families say nothing to each other during dinner.

If Walls Could Talk

From The New York Times:

House Many adults have a fantasy that if they could go back to college — now that the desire to party, drink and sleep around has faded to a burnished memory — they’d get so much more out of it. The publishing industry often reflects this wish. Every season brings offerings that are right at home on anyone’s continuing-ed syllabus: innovative, original ways to study world history through lenses trained on the minutiae of salt or cod, earthworms or spices, tea or telephones. Now, finally, for those of us who wrestled with Rocks for Jocks, pined amid Physics for Poets and schlepped through college on 101s of any and every subject — the beloved survey courses — here’s that most popular professor, Bill Bryson, with a fascinating new book, “At Home: A Short History of Private Life.”

Bryson is best known for “A Short History of Nearly Everything,” which took a cosmic perspective on the creation of the place we call home, our planet — no, make that our solar system — and created a run on yellow highlighters. Why he insists on calling these histories “short” is beyond me, when each runs to more than 450 pages. Perhaps they’re short when compared with the stacks of tomes that have to be ingested, digested and egested in order to produce them? With “At Home,” Bryson’s focus is domestic; he intends, as he puts it, to “write a history of the world without leaving home.” You can take this class in your pajamas — and, judging by the book’s laid-back, comfy tone, I have a sneaking suspicion that Bryson wrote much of it in his.

How the Roberts Court disguises its conservatism

Barry Friedman and Dahlia Lithwick in Slate:

101001_JUR_magicianTN Under the stewardship of its boyish chief justice, John Roberts, the court has taken the law for a sharp turn to the ideological right, while at the same time masterfully concealing it. Virtually every empirical study confirms this rightward turn. Yet recent public opinion polls indicate Americans continue to see a bench that is, if anything, a wee bit too liberal.

How to explain the justices shoving the law rightward, while everyone thinks it is dead center or too far left? The answer is that Roberts is a brilliant magician. He and his four fellow conservative justices have worked some classic illusionist tricks to distract us from seeing the truth. Roberts is likely the first chief justice to understand that the message matters as much as the outcome. He has played his role with consummate skill, allowing the law to shape-shift before our very eyes, even as he and his fellow conservatives claim that nothing is happening.

How does the Roberts Court work its magic in that marble mega-mall of the law? Here, revealed, are the top tricks of the illusionist Roberts Court.

Coloured scanning electron micrographs

Article-1318795-0B875D38000005DC-944_634x532

[Photo above shows eyelash hairs growing from the surface of human skin, magnified 50 times.]

Graham Smith in The Daily Mail:

Bookle-1318795-0B8758E3000005DC-86_306x368 Quite what this industrious little wood ant [on the cover of the book shown here] is planning to do with this microchip is not known, but how appropriate it is that he appears to have a scientific interest.

Because the insect features in a stunning new book featuring the art of the coloured scanning electron micrograph – in the case of this chap magnified 22 times.

Microcosmos takes readers into a secret world of extreme close-ups. Some subjects have been magnified by as much as 22million times.

Detailed descriptions of the subjets are contained within. The wood ant, for example, is a social creature, and acts as a slave for the blood-red ant Formica sanguinea.

Inseminated females of the blood-red ant invade wood ant nests, steal the pupae, and the ants that hatch are made to work for the strange queen.

Compiled by London-based science author Brandon Broll, Microcosmos takes a piercing look at the everyday in six sections including Zoology, The Human Body and Botanics.

The Speech Which Was Never Delivered

William Jennings Bryan’s last speech (never delivered) for the Scopes’ Monkey Trial in 1925 was reprinted the next year as a pamphlet: a tool for believers to combat what they perceived to be a cultural threat — the theory of evolution. He deemed it “the most powerful argument against evolution ever made.”

Reprinted in Skeptic:

Bryans-last-speech-cover Let us now separate the issues from the misrepresentations, intentional and unintentional, that have obscured both the letter and the purpose of the law.

This is not an interference with freedom of conscience. A teacher can think as he pleases and worship God as he likes, or refuse to worship God at all. He can believe in the Bible or discard it; he can accept Christ or reject him. This law places no objections or restraints upon him. And so with freedom of speech, he can, so long as he acts as an individual, say anything he likes on any subject.

This law does not violate any rights guaranteed by any constitution to any individual. It deals with the defendant, not as an individual, but as an employee, an official or public servant, paid by the state, and therefore under instructions from the state.

The right of the state to control the public schools is affirmed in the recent decision in the Oregon case, which declares that the state can direct what shall be taught and also forbid the teaching of anything “manifestly inimical to the public welfare.” The above decision goes even farther and declares that the parent not only has the right to guard the religious welfare of the child, but is in duty bound to guard it. That decision fits this case exactly. The state had a right to pass this law, and the law represents the determination of the parents to guard the religious welfare of their children.

It need hardly be added that this law did not have its origin in bigotry. It is not trying to force any form of religion on anybody. The majority is not trying to establish a religion or to teach it — it is trying to protect itself from the efforts of an insolent minority to force irreligion upon the children under the guise of teaching science.

Even if I am crushed into powder, I will embrace you with the ashes

56619305

If you are curious about Liu Xiaobo, the Chinese dissident who was awarded the Nobel Peace Prize, I don’t think there is a better place to start than the extraordinary document he released in December 2009, as he was awaiting trial on charges of “inciting subversion of state power”: “I Have No Enemies — My Final Statement.” Here are two excerpts, one addressed to his jailers, and one to his wife — one of the most incredible expressions of love I’ve ever read.

But I still want to tell the regime that deprives me of my freedom, I stand by the belief I expressed twenty years ago in my “June Second hunger strike declaration” — I have no enemies, and no hatred. None of the police who monitored, arrested and interrogated me, the prosecutors who prosecuted me, or the judges who sentence me, are my enemies. While I’m unable to accept your surveillance, arrest, prosecution or sentencing, I respect your professions and personalities. This includes Zhang Rongge and Pan Xueqing who act for the prosecution at present: I was aware of your respect and sincerity in your interrogation of me on 3 December. For hatred is corrosive of a person’s wisdom and conscience; the mentality of enmity can poison a nation’s spirit, instigate brutal life and death struggles, destroy a society’s tolerance and humanity, and block a nation’s progress to freedom and democracy. I hope therefore to be able to transcend my personal vicissitudes in understanding the development of the state and changes in society, to counter the hostility of the regime with the best of intentions, and defuse hate with love.

why him, why now?

56600732

The selection Thursday morning of Peruvian novelist Mario Vargas Llosa as winner of the 2010 Nobel Prize for literature raises a familiar question: Why him? Why now? On the one hand, Vargas Llosa is without question a writer of stature, a central figure — along with his one-time friend and fellow Nobel laureate Gabriel Garcia Marquez — in the Latin American “boom” generation of the 1960s and 1970s, the author of such major novels as “The Time of the Hero,” “The Green House” and “Conversation in the Cathedral.” That alone distinguishes him from the last two recipients of the prize, Jean-Marie Gustave le Clézio and Herta Mueller, neither of whom was what anyone would call a household name. At the same time, although Vargas Llosa has continued to work steadily — his most recent novel, “The Bad Girl” (2007), is an updating of sorts of “Madame Bovary” — he hasn’t published a truly significant literary work since 1981’s “The War of the End of the World.” In part, suggests Ilan Stavans, editor of “The Norton Anthology of Latino Literature” and a professor at Amherst College, this has to do with his immersion in politics, which culminated with his unsuccessful 1990 run for the Peruvian presidency.

graphic novel, old school

10heller-span-articleLarge

Long before graphic novels earned a dedicated section in bookstores — indeed, before the term “graphic novel” was even coined — the American wood engraver and illustrator Lynd Ward (1905-85) created six enduring examples of the form. Ward was one of only a handful of artists in the world who bucked literary convention by eliminating all words but the title from standard narrative works. His novels often contained more than 100 ­pages, with one image per right-hand page. The pictures, influenced by German Expressionism, were dark and melodramatic, as though taken directly from an early film noir storyboard. Ward’s thematically related sequences and cinematic pacing bridged the divide between mass comics and the more rarefied illustrated book. Now this groundbreaking work, originally published between 1929 and 1937, has been collected in “Six Novels in Woodcuts,” the first graphic fiction from the Library of America. In his enlightening introduction to this hefty two-volume collection, the editor, Art Spiegelman, notes it was only a few decades ago that extended comics, published in book format with actual spines instead of staples, started being referred to as graphic novels.

Bacteria can walk on ‘legs’

Alan Boyle in MSNBC:

Bac Bacteria have legs? That suggestion seemed surprising to Gerard Wong, a bioengineering professor at the University of California at Los Angeles, when his students told him they were seeing some strange behavior in movies of the microbes. “They said, 'You know, we noticed that some of the bacteria — in fact, a lot of them — popped a wheelie and stood up,” he recalled. “And I said, 'What are you talking about?'” But in a sense, it's true: The movies show that the Pseudomonas aeruginosa bacteria wiggle themselves up into a vertical position and move leglike projections known as Type IV pili to wander around a surface. Wong and his colleagues describe the phenomenon in this week's issue of the journal Science.

You'd think that if bacteria could walk, someone would have noticed it long ago. And it may well have been noticed. But as far as Wong knows, his research team's report is the first systematic set of observations of the behavior. He said that once word got out about the pili phenomenon — for example, at an American Physical Society session in March — he started hearing comments that other researchers were seeing the walking as well. And then came the evolution jokes. “In a way, it's kind of like 'bacteria erectus,'” Wong said. What's next? Opposable thumbs?

The Face of Facebook

From The New Yorker:

Marc Mark Zuckerberg founded Facebook in his college dorm room six years ago. Five hundred million people have joined since, and eight hundred and seventy-nine of them are his friends. The site is a directory of the world’s people, and a place for private citizens to create public identities. You sign up and start posting information about yourself: photographs, employment history, why you are peeved right now with the gummy-bear selection at Rite Aid or bullish about prospects for peace in the Middle East. Some of the information can be seen only by your friends; some is available to friends of friends; some is available to anyone. Facebook’s privacy policies are confusing to many people, and the company has changed them frequently, almost always allowing more information to be exposed in more ways.

According to his Facebook profile, Zuckerberg has three sisters (Randi, Donna, and Arielle), all of whom he’s friends with. He’s friends with his parents, Karen and Edward Zuckerberg. He graduated from Phillips Exeter Academy and attended Harvard University. He’s a fan of the comedian Andy Samberg and counts among his favorite musicians Green Day, Jay-Z, Taylor Swift, and Shakira. He is twenty-six years old.

Friday Poem

I Live on Milk Street

Via Lacta, to be exact. Once it was the path
to Zeus's palace, then a creamy cul de sac; now

they just keep widening and widening. Its origin?
On that the jury's still out. It could have been paved

by the Holy People who crawled to the surface
through a hollow reed, then formed my kind

from ears of white and yellow corn. Some say
it was born of Juno's wrath, wrath that tore

her breast from a suckling infant Hercules
(her no-good hubby once again knocking up

a mortal). What spurted up, they tell me,
begat this little avenue, this broad and ample road

where I merry-go-round with my 200-300
billion neighbors, give or take a billion or two.

(Then again, it might've all been cooked up
by Raven.) My street has the mass

of a trillion suns; my roundabout's a black hole.
My backyard abuts with my dear friend Io's.

She's always asking me to come on over,
but enduring speeds upward of 106,000 mph

usually means I'm waving from the porch.
(On the plus side, the ash from her many volcanoes

does wonders for my whispering bells.) I do wish
I could get to know the Leptons, though.

I invite them to my cookouts, but they're always off
to hither and yon. And I don't mean to be catty,

but it's high time Ms. Nuclear Bulge
ponied up for a some high power Spanx.

I know there's a whole lot else out there-
starbursts, whirlpools, magellanic clouds-

but I'm busy enough keeping up
with the slugs attacking my pole beans,

making sure the garbage goes out. Truth be told, I'm happy
right here where I am, lulled by my own sweet byway's

hazy halo, its harmony of traffic.

Democracy and Moral Conflict

Terence Ball in Notre Dame Philosophical Reviews:

9780521513548 Not so long ago political scientists spoke confidently, if none too felicitously, of “consensus” on “the democratic creed” as a “functional prerequisite” of democracy.[1] In the United States and other western democracies this alleged consensus was attributed to “the genius of American politics,” which was said to be nonphilosophical and anti-ideological (Boorstin); to a “Lockean consensus” which made material interests and property rights central to our politics (Hartz); and even to “the end of ideology” itself (Bell).[2] “Consensus historians” narrated the history of the United States as a story in which conflicts — social, political, ideological, and class — did not loom large but were subsumed under a larger and grander narrative of widespread agreement about what it meant to be an American and a small-d democrat.

Beginning in the 1960s and continuing to this day, this alleged American consensus came under severe strain as students and others protested the Vietnam war, marched against racial segregation and for civil rights, women's rights, gay rights, and (more recently) animal rights and environmental protection. No less significant was the reaction from the right as: the Republican Party nominated Barry Goldwater for president in 1964; the Religious Right rose to political prominence, fueled in large part by objections to (as they saw it) illegitimate, immoral, and unjust Supreme Court decisions allowing abortion and outlawing prayer in public schools; more recently still, Tea Party activists rant about the “radical socialist agenda” of President Obama and have unseated congresspeople they deem insufficiently conservative in bitter and hard-fought primary contests (whether or to what extent they might succeed in the 2010 mid-term elections remains to be seen).

In short, if there once was a fairly seamless American consensus (which I rather doubt, as I shall later explain), there is no longer. This is the ragged backdrop against which Robert Talisse attempts to argue a new and compelling case for democracy in post-consensus America and elsewhere. He writes that at present “our popular democratic politics is driven by insults, scandal, name-calling, fear-mongering, mistrust, charges of hypocrisy, and worse” (p. 1). Hardly Habermas's “ideal speech situation” in which “the forceless force of the better argument” carries the day![3]

Philosophers, political theorists and others who try to account for and make sense of such discord are at a loss to do so in any wholly satisfactory way. Oversimplifying somewhat, two general accounts have emerged of late.

Graphene Will Change the Way We Live

This year's Physics Nobel went to two scientists for their work on graphene. Here's Michio Kaku on graphene in Big Think:

Graphene The theory behind the substance graphene was first explored by theoretical physicist Philip Wallace in 1947 as kind of a starting point when he was doing research trying to understand the electronic properties of more complex, 3D graphite. although the name graphene wasn't actually coined until 40 years later, where it was used to describe single sheets of graphite. In other words, it's the name given to a flat monolayer of carbon atoms that are tightly packed into a 2D honeycomb lattice; like a molecular chicken-wire that is one atom thick. It's essentially the basic building block for graphitic materials of all other dimensionalities; it's a stepping stone to building bigger things. Graphene in itself however wasn't discovered until 2004 in its full observable and testable form.

Since then, in the past 6 years, scientists have discovered that the substance retains some amazing properties. Some say that it will be heralded as one of the materials that will literally change our lives in the 21st century. Not only is graphene the thinnest possible material that is feasible, but it's also about 200 times stronger than steel and conducts electricity better than any material known to man—at room temperature. Researchers at Columbia University's Fu Foundation School of Engineering who proved that graphene is the strongest material ever measured said that “It would take an elephant, balanced on a pencil, to break through a sheet of graphene the thickness of Saran Wrap.”

If you follow my work, you have surely heard me speak about Moore's Law and the race to find a suitable replacement for silicon semi-conductors. Graphene may in fact be the answer to these problems.
