Sandhya Ramesh in The Wire:

Astrophysicists today have released no less than seven papers on one of the biggest events not only reported in the media but also in the known universe. For the first time ever, we have definitive evidence of two neutron stars colliding and releasing a deadly gamma-ray burst. The light from this burst arrived almost simultaneously with gravitational waves unleashed by the collision.

This discovery is further evidence that gravitational waves travel at the speed of light – a prediction that Albert Einstein made over a 100 years ago. Moreover, follow-up observations in the days following the first offered proof that over half the elements heavier than iron are created in such cataclysmic events in the universe.

Earlier this year, the physicist trio of Rainer Weiss, Kip Thorne, and Barry Barish won the Nobel Prize for physics for their contributions to building the gravitational wave detector called LIGO and its first direct detection of gravitational waves in 2015.

According to Einstein’s theory of general relativity, when two massive bodies accelerate or collide with each other, they release gravitational energy. Such energy deforms the spacetime fabric as it travels outwards from the source at the speed of light. Imagine ripples radiating outwards when a rock hits the surface of a still pond. LIGO (Laser Interferometer Gravitational-wave Observatory) is made of two detectors located in the US. It observed one set of waves in September of 2015, when two black holes orbited each other faster and faster, coming closer until they collided. The event occurred 1.4 billion lightyears away and let loose 178.7 billion trillion trillion trillion joules of gravitational energy.

That’s the kind of story you’re likely to hear from Vikram and the people who know him, like Dr PVA Mohandas, a famous surgeon at Vijaya Hospital, who operated on him after his accident. “He had a huge number of friends,” Mohandas said. “A big gang used to assemble in the evenings, during visiting hours.” Mohandas told Vikram’s mother, “I have seen so many actors and politicians here, but I’ve never seen such crowds.”

Claudia Roth Pierpont at The New Yorker:

Walter Isaacson, at the start of his new biography, “Leonardo da Vinci” (Simon & Schuster), describes his subject as “history’s consummate innovator,” which makes perfect sense, since Isaacson seems to have got the idea for writing his book from Steve Jobs, the subject of his previous biography. Leonardo, we learn, was Jobs’s hero. Isaacson sees a particular kinship between the men because both worked at the crossroads of “arts and sciences, humanities and technology”—as did Isaacson’s earlier subjects, Benjamin Franklin and Albert Einstein. For all the unfamiliar challenges this book presents, in terms of history and culture, Isaacson is working a familiar theme. As always, he writes with a strongly synthesizing intelligence across a tremendous range; the result is a valuable introduction to a complex subject. He states right off that he takes the notebooks, rather than the paintings, as his starting point, and it isn’t surprising that he has the most to say when he slows his pace and settles into a (still brief) discussion of optics, say, or the aortic valve. The most sustained and engrossing chapter is largely devoted to Leonardo’s water studies—vortices, floods, cloud formation—and depends on one of the remaining complete notebooks, the Codex Leicester. The codex is currently owned by Bill Gates, who (as Isaacson does not point out) had some of its digitized pages used for a screen saver on the Microsoft operating system.

Isaacson’s Leonardo is a comparably modern figure, not merely “human,” as the author likes to point out, but a blithe societal misfit: “illegitimate, gay, vegetarian, left-handed, easily distracted, and at times heretical.” True enough, although Isaacson sometimes strains the relatability. His Leonardo is lucky to have been born illegitimate—because he was not expected to follow his father into the notary business—and lucky, too, to have been only minimally educated, in math and writing, rather than schooled in the Latin authors reserved for youths of higher rank.

Rowan Williams at The New Statesman:

The story as it unfolds in Europe and the Middle East after the disruption of 1492 is one in which certain themes regularly and depressingly recur. There is the sheer physical insecurity – even for the merchant princes and the viziers of autocrats, a change of ruler or foreign policy could spell disaster, even violent death. There is the conscription of the huge international networks of Jewish traders and brokers into the dismal business of financing the wars and the vanity projects of European monarchs (as Jews had financed the building of abbeys and cathedrals in the Middle Ages).

Jewish financiers had no choice but to bankroll the destructive extravagance of 17th- and 18th-century rulers: while they could exercise limited influence through their wealth, they were also subject to the naked blackmail of knowing that their safety and that of their people depended on keeping monarchs happy, and that they would be the first scapegoats if things went wrong. Adults among spoiled and feral children, Jewish scholars, administrators and bankers serviced the staggering debts of “enlightened” and not so enlightened despots for generation after generation.

Yet again European Jewishness is caught in a catch-22 trap: forbidden entry into “mainstream” professions, Jews are restricted to trade and finance and are then reproached for their obsession with money. The rules of the social and religious game are fixed to make the Jew invariably the loser in the long term.

The Fire Next Time by James Baldwin (1963)

We are living through something of a Baldwin renaissance, in large part thanks to Raoul Peck’s brilliant documentary I Am Not Your Negro. Any number of Baldwin’s books might earn a place on this list, but The Fire Next Time stands out. Consisting of two essays, one addressed to Baldwin’s nephew, it is a passionate and visceral plea to black and white America. It is the only document I know of that expresses the civil rights case as eloquently as the speeches of Martin Luther King.

Discourse on Colonialism by Aimé Césaire (1950)

Published in 1955, when most of Africa was still the colonial possession of one or other of the European powers, Césaire’s masterwork argues that the European empires were, like all empires, run for the profit of the colonising powers, rather than the benefit of the colonised peoples. More controversially, Césaire hypothesised that the roots of Nazism could be found in the toxic soil of imperialism.

Roots by Alex Haley (1976)

What turns a great book into a great political book is its impact, as much as its content. Both on the page and later on the television screen, Alex Haley’s masterpiece was a phenomenon. For African-Americans, whose familial links to Africa had been severed by slavery and racism, it was a revelation. Although Haley’s methodology has been criticised, the cultural impact of Roots remains undeniable.

Dennis Overbye in The New York Times:

Astronomers announced on Monday that they had seen and heard a pair of dead stars collide, giving them their first glimpse of the violent process by which most of the gold and silver in the universe was created. The collision, known as a kilonova, rattled the galaxy in which it happened 130 million light-years from here in the southern constellation of Hydra, and sent fireworks across the universe. On Aug. 17, the event set off sensors in space and on Earth, as well as producing a loud chirp in antennas designed to study ripples in the cosmic fabric. It sent astronomers stampeding to their telescopes, in hopes of answering one of the long-sought mysteries of the universe. Such explosions, astronomers have long suspected, produced many of the heavier elements in the universe, including precious metals like gold, silver and uranium. All the atoms in your wedding band, in the pharaoh’s treasures and the bombs that destroyed Hiroshima and still threaten us all, so the story goes, have been formed in cosmic gong shows that reverberated across the heavens.

This gong show happened when a pair of neutron stars, the shrunken dense cores of stars that have exploded and died, collided at nearly the speed of light. These stars are masses as great as the sun packed into a region the size of Manhattan brimming with magnetic and gravitational fields. Studying the fireball from this explosion, astronomers have concluded that it had created a cloud of gold dust many times more massive than the Earth, confirming kilonovas as agents of ancient cosmic alchemy.

Ben Collyer in New Scientist:

The emergence of state authority was a logical consequence of the move to settled agriculture, or so we thought. Until recently, we also assumed that ancient peoples welcomed the advantages of this way of life as well as the growth of state leadership, since it was key to the development of culture, crafts and civil order.

Over the past 50 years, though, more and more cracks have appeared in this picture. We now know settled agriculture existed for several thousand years before the emergence of the city states of the Near East and Asia. In the past few years, archaeologists have been stunned to find 11,000-year-old structures such as those at Göbekli Tepe, in what is now southern Turkey. These were built by peoples who foraged, and who also developed specialised skills, both artistic and artisanal.

This is a surprise, and leaves researchers busily trying to get the story straight – something that really matters for a number of reasons. Traditional definitions of the state and its authority hinged on the right to raise taxes, and on its legal monopoly on coercing its people, from punishing and imprisoning them to waging formal war.

But as James Scott points out, roughly between 8000 BC and 4000 BC we find settled agricultural communities with developing craft skills – yet no evidence of anything much by way of state authority.

This also poses a key question, one which resonates in the 21st century, about whether there is a necessary link between state power and community life.

Matthew Chalmers in CERN Courier:

Steven Weinberg was 34 when he produced his iconic “Model of Leptons”. The paper marked a moment of clarity in the history of particle physics and gave rise to the electroweak Standard Model, but it was also exceptional in inspiring one of the biggest experimental programmes science has ever seen. Flushing out and measuring its predicted W, Z and Higgs bosons took a multi-billion Swiss-franc effort in Europe that spanned four major projects – Gargamelle, the SPS, LEP and the LHC – and defined CERN’s research programme, keeping experimentalists in gainful employment for at least four decades. Not bad for a theory that, as Weinberg wrote at the time, “has too many arbitrary features for [its] predictions to be taken very seriously”.

Needless to say, Weinberg is delighted to have been able to witness the validation of the Standard Model (SM) over the decades. “I mean, it’s what keeps you going as a theoretical physicist to hope that one of your squiggles will turn out to describe reality,” he says. “I wouldn’t have been surprised or even very chagrined that, although the general idea was right, this particular model didn’t describe nature.”

Today, 50 years after his 1967 insight, Weinberg protests the notion that he is retired. The US has laws against discrimination on the basis of age, he says dryly. “I tell the people here that I plan to retire shortly after I die.” He is currently teaching a course in astrophysics at the University of Texas at Austin, his base for the past 35 years, and has two books and a new cosmology paper in the pipeline. Weinberg spoke to the Courier by phone in September from his home, reflecting on the state of high-energy physics following the Higgs boson discovery and on where the best hopes for new physics might lie. He began by recounting the thought processes that led him to his seminal 1967 work – many of which took place in children’s playgrounds.

Walking the Manhattan blocks near NYU, the poet Rupi Kaur wears a loose cream-colored suit and an air of easy self-assurance. Her hands rest in her pockets, her kimono-shaped jacket hangs open over a cropped black turtleneck, and she comfortably strides her realm: the realm of college freshwomen who have recently been or may soon go through breakups. She looks like someone prepared to tell you convincingly that “you / are your own / soul mate,” to quote one of her poems in its entirety.

Most professional poets cannot expect to be approached by fans. But Milk and Honey, the 25-year-old Punjabi-Canadian’s first collection of poetry, is the best-selling adult book in the U.S. so far this year. According to BookScan totals taken near the end of September, the nearly 700,000 copies Kaur has sold put her ahead of runners-up like John Grisham, J.D. Vance, and Margaret Atwood by a margin of more than 100,000. (In 2016, Milk and Honey beat out the next-best-selling work of poetry — The Odyssey­ — by a factor of ten.) And because Kaur’s robust social-media following (1.6 million followers on Instagram, 154,000 on Twitter) has been the engine of her success, she is accustomed to direct contact with her public. So, when a young woman stops her on the way out of Think Coffee — “I love your work!” — Kaur greets her with a hug, poses for a selfie, then turns and calls back to her publicist. “She preordered the second book!”

On the gray late-summer day when we speak in New York, the October 3 rollout of Kaur’s second collection, The Sun and Her Flowers, is well underway. Entertainment Weekly has published an exclusive look at the book’s cover. Kaur has shared photos of its design (white background, black text, geometric sunflowers) painted across her nude back. And, she reports, the physical copies themselves will go to press the following day. She had scarcely finished finalizing details — “I’m so particular about the spacing and the page and the color” — when her publisher called to tell her that 18 truckloads of paper were on the road. “It really just takes a giant community,” she says. “Some random dude or woman driving this truck is helping millions of people have the book in their hands.”

Rebecca Roache in Aeon:

The year 2010 saw the death of Boa Senior, the last living speaker of Aka-Bo, a tribal language native to the Andaman Islands in the Bay of Bengal. News coverage of Boa Senior’s death noted that she had survived the 2004 tsunami – an event that was reportedly foreseen by tribe elders – along with the Japanese occupation of 1942 and the barbaric policies of British colonisers. The linguist Anvita Abbi, who knew Boa Senior for many years, said: ‘After the death of her parents, Boa was the last Bo speaker for 30 to 40 years. She was often very lonely and had to learn an Andamanese version of Hindi in order to communicate with people.’

Tales of language extinction are invariably tragic. But why, exactly? Aka-Bo, like many other extinct languages, did not make a difference to the lives of the vast majority of people. Yet the sense that we lose something valuable when languages die is familiar. Just as familiar, though, is the view that preserving minority languages is a waste of time and resources. I want to attempt to make sense of these conflicting attitudes.

The simplest definition of a minority language is one that is spoken by less than half of some country or region. This makes Mandarin – the world’s most widely spoken language – a minority language in many countries. Usually, when we talk of minority languages, we mean languages that are minority languages even in the country in which they are most widely spoken. That will be our focus here. We’re concerned especially with minority languages that are endangered, or that would be endangered were it not for active efforts to support them.
