NASA deserves a lot of credit. A space agency funded by 4 percent of the world’s population, it is responsible for launching 100 percent of the rovers that have ever wheeled on Mars; all the probes that have visited Jupiter, Saturn, Uranus, Neptune, and Pluto; nearly all the major space telescopes; and all the people who have ever walked on the Moon. But while its robotic planetary exploration and space astronomy programs continue to produce epic results, for nearly half a century its human spaceflight effort has been stuck in low Earth orbit.

The reason for this is simple: NASA’s space science programs accomplish a lot because they are mission-driven. In contrast, the human spaceflight program has allowed itself to become constituency-driven (or, to put it less charitably, vendor-driven). In consequence, the space science programs spend money in order to do things, while the human spaceflight program does things in order to spend money. Thus, the efforts of the science programs are focused and directed, while those of the human spaceflight program are purposeless and entropic.

This was not always so. During the Apollo period, NASA’s human spaceflight program was strongly mission-driven. We did not go to the Moon because there were three random constituency-backed programs to develop Saturn V boosters, command modules, and lunar excursion vehicles, which luckily happened to fit together, and which needed something to do to justify their funding. Rather, we had a clear goal — sending humans to the Moon within a decade  — from which we derived a mission plan, which then dictated vehicle designs, which in turn defined necessary technology developments. That’s why the elements of the flight hardware set all fit together. But in the period since, with no clear mission, things have worked the other way.

A Cultural Darwinian Analysis of Witch Persecutions

Steije Hofhuis and Maarten Boudry in Cultural Science:

The theory of Darwinian cultural evolution is gaining currency in many parts of the socio-cultural sciences, but it remains contentious. Critics claim that the theory is either fundamentally mistaken or boils down to a fancy re-description of things we knew all along. We will argue that cultural Darwinism can indeed resolve long-standing socio-cultural puzzles; this is demonstrated through a cultural Darwinian analysis of the European witch persecutions. Two central and unresolved questions concerning witch-hunts will be addressed. From the fifteenth to the seventeenth centuries, a remarkable and highly specific concept of witchcraft was taking shape in Europe. The first question is: who constructed it? With hindsight, we can see that the concept contains many elements that appear to be intelligently designed to ensure the continuation of witch persecutions, such as the witches’ sabbat, the diabolical pact, nightly flight, and torture as a means of interrogation. The second question is: why did beliefs in witchcraft and witch-hunts persist and disseminate, despite the fact that, as many historians have concluded, no one appears to have substantially benefited from them? Historians have convincingly argued that witch-hunts were not inspired by some hidden agenda; persecutors genuinely believed in the threat of witchcraft to their communities. We propose that the apparent ‘design’ exhibited by concepts of witchcraft resulted from a Darwinian process of evolution, in which cultural variants that accidentally enhanced the reproduction of the witch-hunts were selected and accumulated. We argue that witch persecutions form a prime example of a ‘viral’ socio-cultural phenomenon that reproduces ‘selfishly’, even harming the interests of its human hosts.

Style and Grammar Guides Suck

Jonathan Russell Clark at The Vulture:

The reason we pay happily for these manuals is straightforward, if a little sad. We’ve been convinced that we need them — that without them, we’d be lost. Readers aren’t drawn to in-depth arguments on punctuation and conjugation for the sheer fun of it; they’re sold on the promise of progress, of betterment. These books benefit from the dire misconception that they are for everyday people, when, in fact, they’re for editors and educators.

Take this year’s Dreyer’s English, whose jacket description reads in part, “We all write, all the time: blogs, books, emails. Lot and lots of emails. And we all want to write better.” Even if we accept the idea that we all (or most of us) want to become clearer and more interesting writers, is grammar truly the key to such improvements?

No, it’s not.

Sound and Resistance in Damon Krukowski’s ‘Ways of Hearing’

Will Meyer at The Baffler:

Contemporary technological anxiety—when not directed towards the internet wholesale—is just as often pitched against sound. We’ve recently started to ask what platform monopolies are doing to the quality of music, or whether Amazon is killing record (and book) stores, or if podcasts are further ensnaring us online, destroying our private thoughts. It’s enough, given his pedagogical wisdom, to make us wonder: What would Berger say?—about earbuds or streambait pop.

To that end, musician and author Damon Krukowski launched a podcast, and now a book, that nods in Berger’s direction. Ways of Hearing is a slim work, really a blown-out podcast script, beautifully designed and illustrated, which takes readers on an admirably reported tour of sound from analog to digital, from 1960s New York to our era of “hyper-gentrification,” all the while considering the relation between noise and power. And, crucially, Krukowski doesn’t privilege a hierarchy between digital and analog but contests it by appreciating—that is, paying attention to—their material differences. All the better to apprehend the political systems that arrange what we hear in the world.

Samuel Coleridge-Taylor’s Violin Concerto

Sudip Bose at The American Scholar:

Coleridge-Taylor was deeply interested in both African and African-American melodies. A meeting with the American writer Paul Laurence Dunbar in 1896, for example, had let to a vocal work, African Romances, with the two of them deciding to put on a series of performances together. Another work, the Twenty-Four Negro Melodies for pianowas influenced by Dunbar’s work. “What Brahms has done for the Hungarian folk music,” Coleridge-Taylor wrote in the preface to the score, “Dvořák for the Bohemian, and Grieg for the Norwegian, I have tried to do for these Negro melodies.” But though the composer’s political consciousness had been informed by an abiding interest in pan-Africanism, though his explorations of his paternal ancestry had him briefly flirting with the idea of relocating to the United States, he primarily filtered the raw materials of black American and African music through a distinctly European sensibility, Brahms and Dvořák being his guiding lights. Coleridge-Taylor’s true métier was the realm of light English music, and as interest in that field diminished with the passing of the 20th century, with the decline of the amateur choruses that once would have taken up such repertoire, so too did an interest in his music. This was already true by 1912, the year the composer died from pneumonia, having collapsed at the West Croydon station, while waiting for a train.

How to survive in a world run by machines

Tim Rogan in New Statesman:

Will the robots of the future be able to replicate human thought? Most engineers assume so with a casual fatalism: the rate of advance in artificial intelligence (AI) is so rapid that it is only a matter of time before robots indistinguishable from human beings are built. Will the robots of the future surpass and then subordinate their creators? Some of the initiated believe so. This impending apocalypse has a name – “the singularity” – and is confidently expected in some quarters as soon as 2045.

Most existing AI systems have a narrow remit. They are task-focused, designed to perform some specific function – recognising speech, say, or diagnosing melanoma. Driven by the aggregation of huge data sets and explosive increases in computer processing power, “machine learning” – a newly effective technique for designing algorithms – is facilitating impressive advances in the capabilities of these systems. Machine learning-trained algorithms now outperform human specialists across a range of applications. But artificial general intelligence (AGI) systems that can imitate human thought, like the robot Hal in Stanley Kubrick’s 2001: A Space Odyssey– which experts have been claiming are “just around the corner” since about 1956 – remain the stuff of science fiction.

Jamie Susskind does not think the distinction between the two forms of artificial intelligence – the specific AI and the human-like AGI – matters much. Specific AIs will be hard enough to handle, creating “vast new opportunities and risks worthy of careful attention in their own right”. If you integrate enough specific AIs into a single interface you might well end up with something so good at giving “the impression of general intelligence” that it is functionally indistinguishable from the AGIs of the engineering imagination. Whether or not AGI fictions like Hal become reality does not matter, Susskind insists. We need to stop debating such distinctions and  knuckle down to the hard work of adapting our politics to a world reshaped by AI.

Building a network that learns like we do

From Simons Foundation:

At each instant, our senses gather oodles of sensory information, yet somehow our brains reduce that fire hose of input to simple realities: A car is honking. A bluebird is flying.

How does this happen?

One part of simplifying visual information is ‘dimensionality reduction.’ The brain, for instance, takes in an image made up of thousands of pixels and labels it ‘teapot.’ One such simplification strategy shows up repeatedly in the brain, and recent work from a team led by Dmitri Chklovskii, group leader for neuroscience at the Center for Computational Biology, suggests the strategy may be no accident.

Consider color. In the brain, one neuron may fire when a person looks at a green teapot, whereas another fires at a blue teapot. Neuroscientists say that these cells have localized receptive fields, as each neuron responds strongly to one hue, collectively spanning the entire rainbow. Similar setups allow us to distinguish aural pitches. Conventional artificial neural networks accomplish similar tasks, such as classifying images, but these algorithms work completely differently from those in the brain. Many artificial networks, for instance, tweak the connections between neurons by using information from distant neurons. In a real brain, however, the strength of a connection predominantly depends only on nearby neurons. However, by extending a tradition of emulating biological learning, Chklovskii and his collaborators developed an approach that is not only biologically plausible but also powerful.

It’s not only the state’s use of facial recognition technology we should worry about

Rachel Connolly in The Baffler:

RECENTLY, some of my friends have started using their faces to pay for things. Not by charming strangers in bars, but instead by using the iPhone Face ID feature, which has users “glance” at their phone to make a contactless payment. The glance is, in reality, usually a close encounter of phone and face.

Face ID uses Automated Facial Recognition (AFR): every time you use it to make a payment, the Apple TrueDepth camera takes a picture of your face, creates a two-dimensional “map” of it by charting the position of facial features over thirty thousand data points, and then compares this to Apple’s stored image of your face. This means every time you use Face ID, Apple anonymously collects data including, but not limited to: the product purchased, the approximate price paid, where and when you bought it, and your facial expression while doing so. You might have preferred to keep using your fingerprint, since the “glance” is inconvenient, but on the new, home buttonless iPhones, Face ID is the default way to use Apple Pay.

I thought of this during the start of an ongoing UK court case, taken by a man named Ed Bridges against South Wales police for their use of AFR. Bridges says he was photographed without warning by a police patrol conducting a trial on a street in Cardiff; UK police have been conducting these unregulated trials, during which they photograph members of the public and compare them to watch lists, for several years. The process is opaque and their criteria for putting together watch lists questionable. Bridges’s legal team has argued that the way police use the technology breaks data protection and equality rules. The verdict will be decided later this year.

Lessons from Shipwrecked Micro-Societies

Nicholas Christakis in Quillette:

Survivor camps established after shipwrecks provide fascinating data about the societies that groups of people make when it’s left up to them, about how and why social order might vary, and about what arrangements are the most conducive to peace and survival. An archipelago of shipwrecks, formed over centuries, more or less at random, has resulted in people participating, unintentionally, in multiple trials of this experiment.

Shipwreck survivors have had a special hold on the human imagination for thousands of years, beginning at least since Homer crafted the Odyssey and stretching through when Shakespeare penned The Tempest, Cervantes described Don Quixote’s marooning, and more modern authors wrote Robinson CrusoeThe Swiss Family Robinson, and Lord of the Flies. In fiction, the castaway narrative tends to feature an idyllic state of nature, following Jean-Jacques Rousseau, or a state of anarchy and violence, following Thomas Hobbes—two philosophers with rather conflicting ideas about human nature.

Hobbesian examples abound in real-world shipwreck situations. Consider the crew of the Batavia, who in 1629 systematically planned the mass murder of women and children to conserve resources.

A New Type of Cooperation the Whole World Needs: Talking to Jeffrey D. Sachs

Andy Fitch in the Los Angeles Review of Books:

ANDY FITCH: A New Foreign Policy takes the sustainable-development framework (prioritizing smart-infrastructure investments, significantly expanded renewable-energy production, more equitable income distribution, tech-fostering education) that you have outlined for various domestic contexts, and applies this to a broader international arena. Could you introduce that sustainable-development approach here by sketching how its basic principles might overlap whether one adopts a domestic- or global-policy vantage — and also by pointing to where this new book might need to provide a slightly different emphasis, argument, agenda? Specifically picking up this book’s subtitle, could you start to sketch how the follies of American-exceptionalist approaches (both at present, and amid a longer arc of US history) might contribute both to the necessity and to the difficulty of adopting this sustainable-development model as a guiding frame for today’s foreign policy?

JEFFREY D. SACHS: Sustainable development applies to each individual country, and also applies globally. In our economic, social, and political life, it aims for prosperous, fair, and environmentally minded societies. Within a United Nations context, most of the world already has accepted these basic principles — dating back to the 1992 Earth Summit in Rio, and then with the Sustainable Development Goals in 2015, and the Paris Climate Agreement in 2015. Of course we haven’t yet fulfilled those goals within our own country, much less globally. So this book (and my writing more generally in recent years) emphasizes the danger we have put ourselves in by not heading in a more sustainable direction. In fact, we seem to have displayed a collective tendency to head away from these goals, towards increased inequality and self-destructive habits ruining the planet.

How Picasso’s Muse Became a Master

Alexandra Schwartz at The New Yorker:

There’s no way to know, of course, if all this happened as Gilot says it did. (Lake said that she had “total recall,” a claim that tends to raise rather than allay suspicions.) She has the memoirist’s prerogative—this is how I remember it—and Picasso’s tyranny and brilliance are hardly in dispute. The bigger mystery is Gilot; the self in her self-portrait can be hard to see behind the lacquered irony and reserve. She goes along with Picasso’s more outlandish demands and schemes, but, she tells us, “not at all for his reasons.” Her dissent is withering and sarcastic rather than furious; like other women of her generation who pointedly overlooked the bad behavior of their husbands, she is concerned with preserving her own dignity. When she is seven months pregnant with Paloma, her doctor (an obstetrician this time) tells her that she is in danger; the labor has to be induced immediately. Alas, this is inconvenient for Picasso, who is due to be at a World Peace Conference elsewhere in Paris the same day.

The Painterly Tenacity of Five Female Artists

Jenni Quilter at the TLS:

Mary Gabriel’s Ninth Street Women charts the rise of five female Abstract Expressionist painters in New York – Lee Krasner, Elaine de Kooning, Grace Hartigan, Joan Mitchell and Helen Frankenthaler – which is a bold move, since all of these women expressed vehement dislike of critics who used their gender as an ordering conceit. To be labelled a “lady painter” or the “wife of the artist” was an exoticization at best, a dismissal at worst. In 1957, Hartigan, Mitchell and Frankenthaler were featured in Life magazine’s feature “Women Artists in Ascendance”, photographed in their studios with their work. Each looks steadily at the camera. They knew the possible benefits of exposure, but they didn’t have to smile. In her introduction, Gabriel tells us that what she has written, “through the biographies of five remarkable women, is the story of a cultural revolution that occurred between the years of 1929 and 1959 as it arose out of the Depression and the Second World War, developed amid the Cold War and McCarthyism, and declined through the early boom years of America’s consumer culture”. Well, yes, but beyond these larger, sweeping assessments of society and gender there is a lot more.

Johny Pitts’s ‘Afropean’

Musa Okwonga at The New Statesman:

At a time where politicians across the world are calling for ever more secure borders, there are books whose mere existence feels radical. Afropean: Notes from Black Europe, by Johny Pitts, feels like one such publication. It is the story of the Sheffield-born author’s travel from his home town across the Continent, visiting several of its major cities and connecting – or not – with people of African heritage as he goes. Crucially, it is also the story of Pitts’s internal journey, to find where he, a working-class, mixed-race man from the north of England, might fit most comfortably within Europe’s complex past and its possibly chaotic future.

It is this constant self-interrogation that elevates the book. “Did ‘Afropean’ include only beautiful, economically successful (and often light-skinned) black people?” he asks himself at the outset.

Me, Me, Me? – nostalgic for community? Think again

Selina Todd in The Guardian:

Remember when everyone left doors unlocked and borrowed cups of sugar? No? Then this richly researched history of community may well appeal. Jon Lawrence uncovers the reality behind romantic cliches of our postwar past. He convincingly suggests that the real history of community is one in which people have combined solidarity with self-reliance and privacy.

This isn’t a new conclusion, as Lawrence acknowledges – his copious notes are a valuable guide for anyone interested in the social histories he draws on. But Me, Me, Me? takes an intriguing route to explore how the myth of community was constructed, and how it might be dismantled. The book revisits several social investigations – ranging from an inner-city area designated for slum clearance to a former mining village – conducted between the 1950s and the 2000s. One of Lawrence’s most vital points is that policymakers and journalists derive their nostalgic notions of “community” from a partial understanding of these studies. A closer reading reveals discontent with overcrowded conditions, frustration at prying neighbours and the hopelessness of poverty. Ambitions were real, people were active and many welcomed the chance to move to spacious housing in the suburbs.

Moving Towards Individualized Medicine For All

Bob Grant in The Scientist:

Personalized medicine. Precision medicine. Genomic medicine. Individualized medicine. All of these phrases strive to express a similar vision—a reality where physicians treat based on each patient’s unique biology. The concept is poised to revolutionize clinical and preventive care. But even as the technologies helping to birth this new breed of medicine mature, the semantics surrounding the phenomenon are still experiencing growing pains. So, what should we call it? For a long time, “personalized medicine” was the preferred nomenclature. In the popular press especially, this was (and often still is) the go-to phrase to describe the medical paradigm shift that is underway. But about eight years ago, a committee convened by the director of the National Institutes of Health recommended jettisoning “personalized medicine” and replacing it with “precision medicine.” This term, the committee argued, “is less likely to be misinterpreted as meaning that each patient will be treated differently from every other patient.”

For now, the closest we’ve gotten to the distant goal has been bucketing patients into subgroups, most often on the basis of their genetics. “Genomic medicine” characterizes this current state of affairs most directly, but the term seems to ignore other unique characteristics—environ­mental factors, lifestyle, microbiomes, etc.—that can also be used to tailor a treatment to a particular patient.

This month’s Reading Frames author Eric Topol, founder and director of the Scripps Research Translational Institute, wrote in a 2014 Cell review article that all of these phrases should be left in the dust, advocating for the use of “individualized medicine” in their place. The individual, he argued, is at the epicenter of this new approach to clinical care. “Be it a genome sequence on a tablet or the results of a biosensor for blood pressure or another physiologic metric displayed on a smartphone,” Topol wrote, “the digital convergence with biology will definitively anchor the individual as a source of salient data, the conduit of information flow, and a—if not the—principal driver of medicine in the future.”

Thursday Poem

Dream Journal

—excerpts

4/3
When you fall into dream,
You are the country – the earth,
the grass, the cows ruminating
over deep bovine philosophies.
You are the ego walking down the lane
that is also yourself, as are the clouds
the sky, the sun, and you are
the observer above all watching
the whole of creation which is,
of course, yourself.
4/4
And yet. – this morning we go
beyond that closed country.
What knelt by your bed
whispering the dream in your ear?
Who thinks your thoughts

so you can listen?

Interview: Going Home with Wendell Berry

Amanda Petrusich in The New Yorker:

Two and a half years ago, feeling existentially adrift about the future of the planet, I sent a letter to Wendell Berry, hoping he might have answers. Berry has published more than eighty books of poetry, fiction, essays, and criticism, but he’s perhaps best known for “The Unsettling of America,” a book-length polemic, from 1977, which argues that responsible, small-scale agriculture is essential to the preservation of the land and the culture. The book felt radical in its day; to a contemporary reader, it is almost absurdly prescient. Berry, who is now eighty-four, does not own a computer or a cell phone, and his landline is not connected to an answering machine. We corresponded by mail for a year, and in November, 2018, he invited me to visit him at his farmhouse, in Port Royal, a small community in Henry County, Kentucky, with a population of less than a hundred.

Berry and his wife, Tanya, received me with exceptional kindness, and fed me well. Berry takes conversation seriously, and our talks in his book-lined parlor were extensive and occasionally vulnerable. One afternoon, he offered to drive me around Port Royal in his pickup truck to show me a few sights: the encroachment of cash crops like soybeans and corn on nearby farms, the small cemetery where his parents are buried, his writing studio, on the Kentucky River. Berry’s connection to his home is profound—several of his novels and short stories are set in “Port William,” a semi-fictionalized version of Port Royal—and his children now run the Berry Center, a nonprofit dedicated to educating local communities about sustainable agriculture.

Sean Carroll’s Mindscape Podcast: A Conversation with Rob Reid on Quantum Mechanics and Many Worlds

Sean Carroll in Preposterous Universe:

As you may have heard, I have a new book coming out in September, Something Deeply Hidden: Quantum Worlds and the Emergence of Spacetime. To celebrate, we’re going to have more than the usual number of podcasts about quantum mechanics over the next couple of months. Today is an experimental flipped podcast, in which I’m being interviewed by Rob Reid. Rob is the host of the After On podcast, of which this is also an episode. We talk about quantum mechanics generally and my favorite Many-Worlds approach in particular, homing in on the motivation for believing in all those worlds and the potential puzzles that this perspective raises.
