The Secret Lives of Leonardo da Vinci

171016_r30728Claudia 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.

Simon Schama’s Jewish history

2017_40_mendozaRowan 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.

From Roots to Black People in Britain: 10 key political texts on black consciousness

David Olusoga in The Guardian:

The Fire Next Time by James Baldwin (1963)

RootsWe 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.

LIGO Detects Fierce Collision of Neutron Stars for the First Time

Dennis Overbye in The New York Times:

StarAstronomers 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.

The real roots of early city states may rip up the textbooks

Ben Collyer in New Scientist:

Grain-300x453The 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.

Physicist Steven Weinberg talks about his seminal 1967 work

Matthew Chalmers in CERN Courier:

CCint1_09_17Steven 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.

The Instagram Poet Outselling Homer Ten to One

Molly Fischer in The Cut:

02-Rupi-Kaur.w512.h600.2xWalking 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.”

Endangered languages have sentimental value, it’s true, but are there good philosophical reasons to preserve them?

Rebecca Roache in Aeon:

ScreenHunter_2860 Oct. 15 18.41The 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.

From The Second Sex to The Beauty Myth

Barbara Ellen in The Guardian:

The Second Sex by Simone de Beauvoir (1949)

SimoneTo ask what influence this book had on gender politics is akin to wondering what the sun ever did for the earth. The answer? Everything. Today, The Second Sex is still hailed as the mothership of feminist philosophy. “One is not born, but rather becomes (a) woman,” muses De Beauvoir (the quote varying, according to the translation). Exploring topics from sex, work and family to prostitution, abortion and the history of female subordination, De Beauvoir challenges the notion of men as the default (the ideal), and women as “other”. For many, The Second Sex represents not just key feminist reading, but rather essential feminist thinking and being.

The Feminine Mystique by Betty Friedan (1963)

This book was no mere pity-party for dissatisfied 1950s/60s Valium-gobbling US housewives. It was a call to arms, demystifying what became known as “second-wave feminism” for ordinary women all over the world. Friedan also identified “the problem that has no name”, probing the lack of fulfilment in women’s lives – where everything “domestic” and trivial was deemed theirs, and everything important was “men only”. With a precision and defiance that still resonates today, The Feminine Mystique challenged the notion that, for women, anatomy was destiny.

Sexual Politics by Kate Millett (1970)

Sexual Politics brought the fizz of iconoclasm to gender politics, tackling how women were routinely diminished and over-sexualised in literature and wider culture. Calling out the likes of Norman Mailer, Henry Miller and DH Lawrence, for what might be politely termed patriarchal/male dominant gender bias, and impolitely, literary macho dick-swinging, Millett set the benchmark for in-depth, no-holds-barred feminist critique. Her book remains relevant today because it encouraged readers to question not just the topics cited, but everything around them and tounderstand better how sexism could be systematically ingrained, culturally as well as politically.

Rushdie’s New York Bubble

Nathaniel Rich in the New York Review of Books:

Rich_1-102617Whether by design, chance, or oracular divination, Salman Rushdie has managed, within a year of the 2016 election, to publish the first novel of the Trumpian Era. On purely technical merits this is an astounding achievement, the literary equivalent of Katie Ledecky lapping the Olympic field in the 1500-meter freestyle. The publishing industry still operates at an aristocratic pace; Egypt built the new Suez Canal in less time than it typically takes to convert a finished manuscript into a hardcover. As a point of comparison, the first novel to appear about September 11, Windows on the World, by the French author Frédéric Beigbeder, was not published until August 2003. Yet less than eight months into the administration, Rushdie has produced a novel that, if not explicitly about the president, is tinged a toxic shade of orange.

Trump poses a risky temptation for novelists, especially those writing amid the shit torrent of his presidency. As political journalists have discovered, the volume of revelations erupting from the White House and the presidential Twitter feed threatens to undermine the reliability of even daily news reports by the time they appear in print. It would seem masochistic to attempt to write a book about such a swiftly moving target, when events could at any time be hijacked by a new revelation of collusion with the enemy, impeachment charges, a nuclear war, a race war. In a nod to the futility of this enterprise, Rushdie uses as an epigram a line from François Truffaut: “La vie a beaucoup plus d’imagination que nous.”

Far more perilous to a novelist, however, is the prospect of writing about a public figure whose name, in the decades before his ascension to the presidency, has carried a fixed set of cultural associations, has been a brand, a trademark, a cliché, appearing in the consciousness if not on the page in boldface type, a textual black hole that threatens to vacuum into itself any gesture toward nuance, complexity, or original thought. Rushdie parries this hazard by omitting Donald Trump’s name and distributing his signature qualities among several characters. The abstraction allows him to scrutinize in turn various aspects of the presidential character, and ours, without succumbing to the familiar catechisms of contemporary political debate.

Bruno Latour, a veteran of the ‘science wars,’ has a new mission

Jop de Vrieze in Science:

ScreenHunter_2859 Oct. 14 19.00French sociologist of science Bruno Latour, 70, has long been a thorn in the side of science. But in the age of “alternative facts,” he’s coming to its defense.

Latour, who retired last month from his official duties at Sciences Po, a university for the social sciences here, shot to fame with the 1979 book Laboratory Life: The Construction of Scientific Facts, written with U.K. sociologist Steve Woolgar. To research it, Latour spent 2 years at the Salk Institute for Biological Studies in San Diego, California, acting as an anthropologist observing scientists at work. In 1987, Latour elaborated on his thinking in the textbook Science in Action.

Central to Latour’s work is the notion that facts are constructed by communities of scientists, and that there is no distinction between the social and technical elements of science. Latour received praise for his approach and insights, but his relativist and “social-constructivist” views triggered a backlash as well. In their 1994 book Higher Superstition: The Academic Left and its Quarrels with Science, biologist Paul Gross and mathematician Norman Levitt accused Latour and other sociologists of discrediting their profession and jeopardizing trust in science.

The heated debate that followed, known as the “science wars,” lasted for many years. In later writings, Latour acknowledged that the criticism of science had created a basis for antiscientific thinking and had paved the way in particular for the denial of climate change, now his main topic. Today, he hopes to help rebuild confidence in science.

Science Insider spoke with Latour in his apartment here in the French capital. This interview has been edited for clarity and brevity.

Two new books on the environment show that left vs. right is no longer the relevant political divide

Alex Trembath in Slate:

151211_FUT_BOOKS.jpg.CROP.promo-xlarge2In 1980, Stanford ecologist Paul Ehrlich famously bet libertarian economist Julian Simon that the price index of several precious metals would increase over the ensuing 10 years. Ehrlich, author of the apocalyptic hit The Population Bomb, expected that resource scarcity would inevitably drive up prices. Simon took the bet, insisting that the free market and human ingenuity would find ways to produce more resources at lower costs. Simon won.

That wager, expertly recalled in Paul Sabin’s The Bet, is a microcosm of the left-right divide on the environment and economic growth that has existed for the past several decades. Ehrlich was on the left: an angry, pessimistic academic demanding government policy to halt the growth of population, technology, and consumption. Simon was on the right: a sunny, gregarious economist arguing the free market would forever solve humanity’s resource challenges and that government should get the hell out of the way. Lefties and righties across Western economies have played these roles consistently for a generation.

That divide no longer matters.

Is there a doctor in my pocket?

Natasha Loder in 1843:

HealthHumans have always dreamed of better, fitter, longer-lasting bodies. But while many science-fiction fantasies, from videophones to self-driving cars, have been realised, health technology has lagged behind our hopes. Artificial organs and smart pills have been a long time coming. There are a number of reasons for this. Biology is an order of magnitude more complicated than other forms of engineering. And it is hard to innovate in health, as there are many rules to protect us from products that might otherwise kill us. The pill or device that promises a longer life needs to prove that it actually works before it can be sold. The price of patient safety is sluggish innovation. Yet, despite these obstacles, there are signs that a digital revolution in health care is imminent. It will be more personalised, and potentially more useful, than anything the world has seen before. It promises to help us manage our health and inform us about the risks ahead.

…Britain’s Babylon Health, based in Kensington in London, is particularly ambitious. At its offices, fake greenery and flowering plants proliferate in a largely unsuccessful attempt to evoke the Hanging Gardens of Babylon. Its app answers medical queries, provides access to doctors and offers users a dashboard of their health stats drawn from the phone or supplemental devices. These data can be supplemented with results from at-home blood-testing kits that one can order via the app. These take readings of liver and kidney function, vitamin levels, bone density and cholesterol. I tried the thyroid test and drew blood with a special device that punches a tiny hole with surprisingly little pain. Then I posted the sample to Babylon. The results (all OK) popped up in the app a day later. If Babylon recommends an appointment with a doctor, it can provide one via video-conferencing almost immediately for £25 ($32). As with many other doctor-on-demand services, it is possible to share notes, or even a video from a consultation, with your regular doctor.

One of the most exciting aspects of digital health is the capacity of mobile phones to gather information as well as deliver it. They can collect data from their own sensors and screens, as well as associated devices such as watches, headbands and the growing constellation of add-ons. Increasingly, such devices are clinically validated and medically useful.

President Clinton Looks Back at President Grant

Bill Clinton in The New York Times:

GrantThis is a good time for Ron Chernow’s fine biography of Ulysses S. Grant to appear, as we live with the reality of Faulkner’s declaration, “The past is never dead, it’s not even past.” We are now several years into revisiting the issues that shaped Grant’s service in the Civil War and the White House, from the rise of white supremacy groups to successful attacks on the right of eligible citizens to vote to the economic inequalities of the Gilded Age. In so many ways “Grant” comes to us now as much a mirror as a history lesson. As history, it is remarkable, full of fascinating details sure to make it interesting both to those with the most cursory knowledge of Grant’s life and to those who have read his memoirs or any of several previous biographies. It tells well the story of a country boy’s unlikely path to leadership, his peculiarities, strengths, blind spots and uncanny powers of concentration and courage during battle. It covers Grant’s amazing feats on horseback at West Point, where in jumping hurdles “he exceeded all rivals,” clearing the bar a foot higher than other cadets. His mediocre grades have long obscured his interests and abilities: He was president of the literary society, had a talent for drawing and was trusted by classmates to mediate disputes.

For all its scholarly and literary strengths, this book’s greatest service is to remind us of Grant’s significant achievements at the end of the war and after, which have too long been overlooked and are too important today to be left in the dark. Considered by many detractors to be, as a general, little more than a stoic butcher, Grant, in the written terms of surrender at Appomattox, showed the empathy he felt toward the defeated and downtrodden — conditions he knew from harsh personal experience. The terms presented to Robert E. Lee carried “no tinge of malice” and “breathed a spirit of charity reminiscent of Lincoln’s Second Inaugural Address.” He notably allowed the exhausted and starving Confederate regulars to keep their mules and horses, knowing from the rough experience of his failed Missouri farm (Grant presciently named its log cabin “Hardscrabble”) that only by putting in a crop as soon as they returned home would these destitute farmers — and their families — have a chance to survive the coming winter. Grant also knew that if the country had any chance of being brought back together, it needed something other than a harsh peace. In making national healing a priority, he — like Lincoln — took the long view.

Incomprehensible Things: Philosophy and the Mexico Earthquake

Emmanuel Ordóñez Angulo in The Point:

ScreenHunter_2858-Oct.-13-18.29This summer was my longest stay back home, in Mexico City, in my life as a philosophy student abroad. Because of course I failed to meet my goal of finishing coursework before the holiday, I went back to the studio space I used to rent for writing in Colonia Juárez, near the city centre. By “studio space” I mean the one unusable corner of an apartment in an early twentieth-century building that, the landlord claims, used to house the British diplomatic corps prior to the Mexican revolution, and that now brims with wild flora and peeling green walls.

It was there that the earthquake found me.

The essay I was grappling with deals with the old question whether the things we perceive—the things that we see and touch—have a reality that is independent of us. The relevant discussion starts with Immanuel Kant’s argument against Descartes’ skepticism about the empirical world.

While Descartes aimed to show that the only thing I can be certain of is my own existence, Kant argued that in order for that to be possible I need to in fact be aware of the world around me as actually existing independent of me. This is because, if I am aware of my existence as flowing in time, as I am, then there must be something fixed by reference to which I can be aware that I am not fixed but flowing. Precisely because Descartes is right that I can be certain that I exist, says Kant, I must be certain that a world distinct from me exists as well.

This argument is liable to numerous objections. A famous one, raised by contemporary philosopher Barry Stroud, is that Kant reasons illegitimately from a premise about subjective experience to a conclusion about the existence of objective reality. The problem is that one field of inquiry concerns how we experience and know the world, i.e. what our conceptual framework is like, while the other concerns what actually exists. According to Stroud, the most Kant’s premise can prove is that we experience the external world as existing.
