NASA Langley Research Center Chief Scientist on AI, Mars Colonization & Spaceflight

Tim Ventura in Predict:

Dennis, let’s start out by asking about the Vision for Space Exploration and how that relates to human expeditions to Mars. Taking into account all the political & economic uncertainty over the last few years, are human missions to Mars is still a definite yes for NASA?

Mars is a definite yes — it’s not a matter of ‘if’, but ‘when’. We need to do Mars both safely and affordably, but with today’s technologies what’s safe is not affordable and what’s affordable is not safe.

What we’re trying to do right now is to invent new technologies to reduce the cost sufficiently so that we can afford the right safety, and then we can go. The estimates are that it will take 15 years to complete the research and another 15 years for development — that puts us about 30 years out from Mars.

Jill Lepore has Schlesinger-like aspirations, albeit updated for the twenty-first century

Meg Jacobs in Democracy:

In her latest book, Jill Lepore, a brilliant story teller, offers us the biggest story of all: who we are and how we came to be. She did that superbly in her one-volume history of the nation, These Truths (2018). But here the effort is more pointed; here, Lepore is telling the story of the past in order to fight the battles of today, and she is urging her fellow historians to join her in the campaign. By mapping out the past as a competition between liberal and illiberal nationalisms, the latter most recently reincarnated and promoted by the President of the United States, Lepore is directly entering into the political fray. Unless liberals embrace and reclaim the idea of American nationalism, they will surrender its meaning to Trump and his supporters. What’s needed, and what her history shows is possible, is a full throated defense of civic patriotism, celebrating a “dedication to equality, citizenship, and equal rights, as guaranteed by a nation of laws.” “A new Americanism,” she writes on her final pages, “would mean a devotion to equality and liberty, tolerance and inquiry.”

40 books to read before you die

Ceri Radford and Chris Harvey in The Independent:

Books, books, books. They will increase your lifespan, lower your stress and boost your intelligence. They will give you fuller, thicker hair.

Whatever the breathless claims about reading, one thing is certain: losing yourself in a great novel is one of life’s most enduring and dependable joys. Job satisfaction comes and goes, partners enrapture and abscond, but you can always fall back on the timeless ability of literature to transport you to a different world. From Jane Austen’s mannered drawing rooms to the airless tower blocks of 1984, novels do something unique. They simultaneously speak to the heart and mind. They teach you about the history of our world, the possibilities of our future and the fabric of our souls.

So where do you start? It’s a fraught question, because the obvious answer – “the literary canon” – means a pantheon of predominantly dead, white dudes. The power structures at play for centuries have meant that a very narrow band of people have been given the opportunity to say something universal about the human condition. It’s impossible to ignore these biases: the least we can do is acknowledge them, include different perspectives, and point to some excellent resources herehere and here to discover more writers we should be reading. As it stands, whittling this list down to 40 novels has been a process that makes Brexit negotiations look simple and amicable. We hope you enjoy the selection – or at least enjoy arguing about who should or should not have made the cut.

The Brain Senses Touch beyond the Body

Richard Sima in Scientific American:

Luke Miller, a cognitive neuroscientist, was toying with a curtain rod in his apartment when he was struck by a strange realization. When he hit an object with the rod, even without looking, he could tell where it was making contact like it was a sensory extension of his body. “That’s kind of weird,” Miller recalls thinking to himself. “So I went [to the lab], and we played around with it in the lab.”

Sensing touch through tools is not a new concept, though it has not been extensively investigated. In the 17th century, philosopher René Descartes discussed the ability of blind people to sense their surroundings through their walking cane. While scientists have researched tool use extensively, they typically focused on how people move the tools. “They, for the most part, neglected the sensory aspect of tool use,” Miller says.

In a 2018 Nature study, Miller and his colleagues at Claude Bernard Lyon 1 University in France reported that humans are actually quite good at pinpointing where an object comes into contact with a handheld tool using touch alone, as if the object were touching their own skin. A tool is not innervated like our skin, so how does our brain know when and where it is touched? Results in a follow-up study, published in December in Current Biology, reveal that the brain regions involved with sensing touch on the body similarly processes it on the tool. “The tool is being treated like a sensory extension of your body,” Miller says.

The Two Popes

Rita Ferrone at Commonweal:

The most glorious journey can begin with a mistake.” This is the observation made by Cardinal Jorge Mario Bergoglio in the opening scene of Fernando Meirelles’s The Two Popes, as he preaches to throngs of poor people in a Buenos Aires slum. It signals the central themes of the film: change, reconciliation, and hope for the future. The scene, shot on location in Argentina, surges with the energy of the people and the place. A kaleidoscope of color and activity soon settles into a moment of stillness and focused attention as Bergoglio speaks. He stands in the midst of all these people: not above them, but with them. And they are listening.

But what is the mistake? The first possible answer the film offers is that Bergoglio (played by Jonathan Pryce) has decided to resign from his position at the head of the church of Buenos Aires. He is tired and weary from the direction that the church is taking, and he wants out.

“Bold Climate Action” Does Not Mean What You Think It Means

Katy Lederer at n+1:

Meanwhile, Saudi Arabia’s Aramco IPO last month was the biggest in world history. Valued anearly two trillion dollars, it is worth over 50 percent more than Apple or Microsoft. Even American billionaires like Warren Buffet and Sam Zell have gone long on continuing extraction. According to a recent piece in the Financial Times, they have been quietly buying up fossil fuel assets. “If Mr. Buffet and others are correct . . . that companies have been oversold, and are now trading at prices that imply a calamity that will not come,” the piece explains, “then the energy sector could be one of the big winners in 2020 and in the years to come.” The “calamity” the piece references is the possibility that global demand for oil and gas falls off.”

On Sunday, December 15, after the Madrid COP finally came to a close, António Guterres, the Secretary General of the U.N., openly expressed his disappointment on Twitter.

Reading in the Age of Constant Distraction

Mairead Small Staid at The Paris Review:

Birkerts’s argument (and mine) isn’t that books alleviate loneliness, either: to claim a goal shared by every last app and website is to lose the fight for literature before it starts. No, the power of art—and many books are, still, art, not entertainment—lies in the way it turns us inward and outward, all at once. The communion we seek, scanning titles or turning pages, is not with others—not even the others, living or long dead, who wrote the words we read—but with ourselves. Our finest capacities, too easily forgotten.

Early in The Gutenberg Elegies, Birkerts summarizes historian Rolf Engelsing’s definition of reading “intensively” as the common practice of most readers before the nineteenth century, when books, which were scarce and expensive, were often read aloud and many times over.

From Literary Hub:

Happy Holidays, fellow Schadenfreuders.

As longtime devotees will know, for one day and one day only here at Book Marks—a wholesome and benevolent institution dedicated to helping readers find the books they’ll love by spotlighting the best in contemporary literary criticism—we your friendly neighborhood book review aggregators put on our black hats and seek out the most deliciously virulent literary take-downs of the past twelve months. It’s a ritual blood-letting exercise carried out in an effort appease the Literary Gods, thereby guaranteeing a good book review harvest in the year to come, and we take it very seriously.

Among the books lying prone on the sacrificial altar this year: E. L. James’ brain-bleaching Fifty Shades follow-up, Bret Easton Ellis’ needy screed against millennials, David Cameron’s bitter ooze of a memoir, and, of course, another Sean Penn novel.

Let’s get the knives out.

Sean Carroll’s Holiday Message On Publishing Books

Sean Carroll in Preposterous Universe:

Welcome to the second annual Mindscape Holiday Message! No substantive content or deep ideas, just me talking a bit about the state of the podcast and what’s on my mind. Since the big event for me in 2019 was the publication of Something Deeply Hidden, I thought it would be fun to talk about the process of writing and selling a popular book. Might be of interest to some of you out there!

Why Fascism is the Wave of the Future

Edward Luttwak, 25 years ago, in the London Review of Books:

That capitalism unobstructed by public regulations, cartels, monopolies, oligopolies, effective trade unions, cultural inhibitions or kinship obligations is the ultimate engine of economic growth is an old-hat truth now disputed only by a few cryogenically-preserved Gosplan enthusiasts and a fair number of poorly-paid Anglo-Saxon academics. That the capitalist engine achieves growth as well as it does because its relentless competition destroys old structures and methods, thus allowing more efficient structures and methods to rise in their place, is the most famous bit of Schumpeteriana, even better-known than the amorous escapades of the former University of Czernowitz professor. And, finally, that structural change can inflict more disruption on working lives, firms, entire industries and their localities than individuals can absorb, or the connective tissue of friendships, families, clans, elective groupings, neighbourhoods, villages, towns, cities or even nations can withstand, is another old-hat truth more easily recognised than Gemeinschaft and Gesellschaft can be spelled.

What is new-hat about the present situation is only a matter of degree, a mere acceleration in the pace of the structural changes that accompany economic growth, whatever its rate. But that, as it turns out, is quite enough to make all the difference in the world.

Letter from The Comoro Islands

Tommy Trenchard at Harper’s Magazine:

had been in Domoni—an ancient, ramshackle trading town on the volcanic island of Anjouan—for only a few summer days in 2018 when Onzardine Attoumane, a local English teacher, offered to show me around the medina. Already I had gotten lost several times trying to navigate the dozens of narrow, seemingly indistinguishable alleyways that zigzagged around the old town’s crumbling, lava-rock homes. But Onzardine had grown up in Domoni and was intimately familiar with its contours.

Stocky in build, with small, deep-set eyes and neatly trimmed stubble, Onzardine led me through the backstreets, our route flanked by ferns and weeds sprouting from cracks in the walls and marked by occasional piles of rubble. After a few minutes, we emerged onto a sunlit cliff offering views of the mustard-colored hills that surround the town, dotted with mango, palm, and breadfruit trees.

Toni Morrison’s Democracy of Vision

Michael Ondaatje at the NYRB:

When has a voice been this intimate, and versatile? Affectionate, far-reaching, self-aware, and also severe, dismissive of fools?

There’s this range in the manner of Toni Morrison’s voice. She is always full of swerves—from humor, to anger, to music. We see all that in the narrator of Jazz who holds this remarkable novel together.

“I like the feeling of a told story,” Morrison has said, “where you can hear a voice but you can’t identify it. It’s a comfortable, guiding voice, alarmed by the same things that the reader is alarmed by, and it doesn’t know what’s going to happen either… To have the reader work with the author in the construction of the book—is what’s important.”

We are always participating when we read Toni Morrison. During a quiet lull, the Narrator will remember—“And another damn thing.”

What Can a Novelist Do to Tackle The Climate Crisis?

India Bourke at The New Statesman:

Kim Stanley Robinson is, uncharacteristically, at a loss. As a science fiction writer, he is famed for dreaming up utopian futures. But when we meet for lunch in his Californian hometown, at times he struggles to maintain his cool.

“What the hell do we write at this point in history?” he asks. “My utopia has reached this low bar: if we avoid a mass extinction event, then, ‘Yay! Leave it at that.’”

Robinson has not always felt so cynical. Across a career spanning over 30 years, he has built a reputation as a pragmatic optimist. From his breakthrough Mars trilogy in the 1990s, about colonising the barren planet, to his latest novel, Red Moon, set at a lunar mine and in China, his novels have deployed science and diplomacy to explore how crises might play out in similar-but-better political worlds. If the Gulf Stream stalls, try adding salt. If climate change exacerbates cross-border conflict, try building better structures of international cooperation.

Tackling Inflammation to Fight Age-Related Ailments

Jane Brody in The New York Times:

The quest for a fountain of youth is many centuries old and marred by many false starts and unfulfilled promises. But modern medical science is now gradually closing in on what might realistically enable people to live longer, healthier lives — if they are willing to sacrifice some popular hedonistic pleasures. Specialists in the biology of aging have identified a rarely recognized yet universal condition that is a major contributor to a wide range of common health-robbing ailments, from heart disease, diabetes and cancer to arthritis, depression and Alzheimer’s disease. That condition is chronic inflammation, a kind of low-grade irritant that can undermine the well-being of virtually every bodily system.

Chronic inflammation occurs to varying degrees with advancing age in all mammals independent of any existing infection. Researchers call it “inflammaging.” As Roma Pahwa of the National Cancer Institute and Dr. Ishwarlal Jialal of California Northstate University put it in a recent report, “Although chronic inflammation progresses slowly, it is the cause of most chronic diseases and presents a major threat to the health and longevity of individuals.” However, recent studies have identified measures potentially available to everyone that can minimize the potency of chronic inflammation and stymie — and possibly even reverse — its progression. The measures will come as no surprise to people familiar with the healthful advice that has been offered in this column for many years: Adopt a wholesome diet (details to follow), get regular exercise, avoid or reduce excess weight, get adequate quality sleep, minimize stress and don’t smoke.

The unpalatable truth about veganism and climate change

Hephzibah Anderson in Prospect:

Ultimately, motivation is irrelevant—who cares if companies are merely pursuing the vegan pound, or if some self-declared “vegans” are self-obsessed wellness slaves ditching dairy for vanity’s sake? If they’re part of a movement that might help slam the brakes on impending environmental doom, then they are surely a force for good.

But are they? A 2019 Imperial College study did find that your diet is where you can make the biggest difference. The trouble is, while certain facts are indisputable—for instance, the amount of soya fed to a cow to produce a litre of milk is several times that used to produce a litre of soya milk—the more granular the focus, the murkier the picture becomes. Industrially-farmed soya is one of the worst crops in any quantity because it’s what is known as a monocrop, one that is planted in the same field year after year, causing soil depletion and also enhancing vulnerability to famine, Irish potato-style. So, sure, you’ve embraced a plant-based diet, but if you’re indulging every week in jackfruit tacos, prefer almond milk to oat milk, and aren’t yet sick of avocados, then your diet is hardly carbon-neutral. Even fruitarians have been found to have a high environmental impact.

Jürgen Habermas offers a framework for action on climate change

Emilie Prattico in Aeon:

And so, while the requirement for scientific and technical expertise about climate change cannot be denied, there are ways to reconcile this reality with the needs for inclusive, democratic processes about climate action. In his theory of deliberative democracy, the German philosopher Jürgen Habermas (1929-) provides a framework within which democratic processes can distinguish between the different dimensions of discourse – scientific-pragmatic and moral-political. In the context of climate change, this means that there are pathways to address the problem that don’t require scientific or technical expertise, and that are geared towards tackling the collective issues it raises democratically.

Habermas’s version of deliberative politics is rooted in his theory of communicative action. There are several reasons for singling out Habermas here. First of all, the spectre of technocratic rule has guided his work since the 1960s. More significantly, however, Habermas has consistently recognised the value of the ‘substantive’ aspect of political decisions, setting him in a tradition of democratic thought concerned with finding the adequate balance between the democratic requirement of equal respect for each citizen and the recognition that the substantive and technical quality of citizens’ contributions varies.

Are Americans Overdoing Democracy?

Oliver Traldi in The National Review:

For the past several years, there has been a flood of commentary about how politics is poisoning social life, from first-person stories about “surviving” holidays or breaking off romantic relationships to surveys about the precipitous drop in inter-partisan friendships on college campuses. There are many who think this is a reasonable state of affairs: that “the personal is political” and that it is therefore only natural that all of a person’s social perceptions and choices be suffused with the eerie light of political analysis. But there are also those who dissent. These dissenters say that Americans need to relearn how to disagree with one another productively; the strength of our public dialogue and of our democratic process itself may depend, this crowd says, on our having more and better political discussion and more interactions with those outside our bubbles.

In his new book, Robert Talisse, a philosophy professor at Vanderbilt University, agrees with the dissenters that our politically polarized and politically saturated culture is not in good shape. But he disagrees about the solution. “Calls for bipartisanship and cooperation are insufficient,” Talisse writes, “and in a way misguided. More and better politics cannot be the solution . . . because politics is the problem.” Americans are “overdoing democracy in that politics has become practically inescapable,” and hence “we have to put politics in its place.”
