"Divine Inspiration" by Jeet Heer | The Walrus | July 2011 - 0 views

  • The Mechanical Bride, published in 1951, he established himself in the emerging field of cultural studies by offering a caustic survey of the dehumanizing impact of popular magazines, advertising, and comic strips.
  • In The Gutenberg Galaxy, he offered a map of modern history by highlighting the hitherto-unexplored effect of print in shaping how we think. This was followed by Understanding Media, which prophesied that new electronic media would rewire human consciousness just as effectively as print once did, giving birth to a “global village”

So Many Earth-Like Planets, So Few Telescopes - NYTimes.com - 0 views

  • Astronomers announced on Tuesday that they had found eight new planets orbiting their stars at distances compatible with liquid water, bringing the total number of potentially habitable planets in the just-right “Goldilocks” zone to a dozen or two
  • As the ranks of these planets grow, astronomers are planning the next step in the quest to end cosmic loneliness: gauging which hold the greatest promise for life and what tools will be needed to learn about them.
  • recalled that the first discovery of a planet orbiting another normal star, a Jupiter-like giant, was 20 years ago. Before that, she said, astronomers worried that “maybe the ‘Star Trek’ picture of the universe was not right, and there is no life anywhere else.”

  • yet we still do not have a clue that we are not alone.
  • Finding Goldilocks planets closer to home will be the job of the Transiting Exoplanet Survey Satellite, to be launched in 2017. But if we want to know what the weather is like on these worlds, whether there is water or even life, more powerful instruments will be needed.
  • hundreds of light-years away, too far for detailed study. We will probably never know any more about these particular planets than we do now.
  • “but until we can observe the atmospheres and assess their greenhouse gas power, we don’t really know what the surface temperatures are like.”
  • Kepler has discovered 4,175 potential planets, and 1,004 of them have been confirmed as real

  • The goal is to have a pool of dozens of “exo-Earths” to study in order to have any chance of seeing signs of life or understanding terrestrial planets
  • perhaps because as planets get bigger their mass and gravity increase, and they are better able to hang on to gas and lighter components.

Op-Ed Contributor - Rich Man's Burden - Op-Ed - NYTimes.com - 0 views

  • what’s different from Weber’s era is that it is now the rich who are the most stressed out and the most likely to be working the most. Perhaps for the first time since we’ve kept track of such things, higher-income folks work more hours than lower-wage earners do.
  • This is a stunning moment in economic history: At one time we worked hard so that someday we (or our children) wouldn’t have to. Today, the more we earn, the more we work, since the opportunity cost of not working is all the greater (and since the higher we go, the more relatively deprived we feel).
  • when we get a raise, instead of using that hard-won money to buy “the good life,” we feel even more pressure to work since the shadow costs of not working are all the greater.

  • One of these forces is America’s income inequality, which has steadily increased since 1969. We typically think of this process as one in which the rich get richer and the poor get poorer. Surely, that should, if anything, make upper income earners able to relax.
  • technology both creates and reflects economic realities. Instead, less visible forces have given birth to this state of affairs.
  • even with the same work hours and household duties, women with higher incomes report feeling more stressed than women with lower incomes, according to a recent study by the economists Daniel Hamermesh and Jungmin Lee. In other words, not only does more money not solve our problems at home, it may even make things worse.
  • t it turns out that the growing disparity is really between the middle and the top. If we divided the American population in half, we would find that those in the lower half have been pretty stable over the last few decades in terms of their incomes relative to one another. However, the top half has been stretching out like taffy. In fact, as we move up the ladder the rungs get spaced farther and farther apart.
  • The result of this high and rising inequality is what I call an “economic red shift.” Like the shift in the light spectrum caused by the galaxies rushing away, those Americans who are in the top half of the income distribution experience a sensation that, while they may be pulling away from the bottom half, they are also being left further and further behind by those just above them.
  • since inequality rises exponentially the higher you climb the economic ladder, the better off you are in absolute terms, the more relatively deprived you may feel. In fact, a poll of New Yorkers found that those who earned more than $200,000 a year were the most likely of any income group to agree that “seeing other people with money” makes them feel poor.
  • Because these forces drive each other, they trap us in a vicious cycle: Rising inequality causes us to work more to keep up in an economy increasingly dominated by status goods. That further widens income differences.
  • if you are someone who is pretty well off but couldn’t stop working yesterday nonetheless, don’t blame your iPhone or laptop. Blame a new wrinkle in something much more antiquated: inequality.

Liu Cixin's War of the Worlds | The New Yorker - 0 views

  • he briskly dismissed the idea that fiction could serve as commentary on history or on current affairs. “The whole point is to escape the real world!” he said.
  • Chinese tech entrepreneurs discuss the Hobbesian vision of the trilogy as a metaphor for cutthroat competition in the corporate world; other fans include Barack Obama, who met Liu in Beijing two years ago, and Mark Zuckerberg. Liu’s international career has become a source of national pride. In 2015, China’s then Vice-President, Li Yuanchao, invited Liu to Zhongnanhai—an off-limits complex of government accommodation sometimes compared to the Kremlin—to discuss the books and showed Liu his own copies, which were dense with highlights and annotations.
  • In China, one of his stories has been a set text in the gao kao—the notoriously competitive college-entrance exams that determine the fate of ten million pupils annually; another has appeared in the national seventh-grade-curriculum textbook. When a reporter recently challenged Liu to answer the middle-school questions about the “meaning” and the “central themes” of his story, he didn’t get a single one right. “I’m a writer,” he told me, with a shrug.
  • ...20 more annotations...
  • Liu’s tomes—they tend to be tomes—have been translated into more than twenty languages, and the trilogy has sold some eight million copies worldwide. He has won China’s highest honor for science-fiction writing, the Galaxy Award, nine times, and in 2015 he became the first Asian writer to win the Hugo Award, the most prestigious international science-fiction prize
  • Liu believes that this trend signals a deeper shift in the Chinese mind-set—that technological advances have spurred a new excitement about the possibilities of cosmic exploration.
  • Concepts that seemed abstract to others took on, for him, concrete forms; they were like things he could touch, inducing a “druglike euphoria.” Compared with ordinary literature, he came to feel, “the stories of science are far more magnificent, grand, involved, profound, thrilling, strange, terrifying, mysterious, and even emotional
  • Pragmatic choices like this one, or like the decision his grandparents made when their sons were conscripted, recur in his fiction—situations that present equally unconscionable choices on either side of a moral fulcrum
  • The great flourishing of science fiction in the West at the end of the nineteenth century occurred alongside unprecedented technological progress and the proliferation of the popular press—transformations that were fundamental to the development of the genre
  • Joel Martinsen, the translator of the second volume of Liu’s trilogy, sees the series as a continuation of this tradition. “It’s not hard to read parallels between the Trisolarans and imperialist designs on China, driven by hunger for resources and fear of being wiped out,” he told me. Even Liu, unwilling as he is to endorse comparisons between the plot and China’s current face-off with the U.S., did at one point let slip that “the relationship between politics and science fiction cannot be underestimated.”
  • Speculative fiction is the art of imagining alternative worlds, and the same political establishment that permits it to be used as propaganda for the existing regime is also likely to recognize its capacity to interrogate the legitimacy of the status quo.
  • Liu has been criticized for peopling his books with characters who seem like cardboard cutouts installed in magnificent dioramas. Liu readily admits to the charge. “I did not begin writing for love of literature,” he told me. “I did so for love of science.”
  • “The Three-Body Problem” takes its title from an analytical problem in orbital mechanics which has to do with the unpredictable motion of three bodies under mutual gravitational pull. Reading an article about the problem, Liu thought, What if the three bodies were three suns? How would intelligent life on a planet in such a solar system develop? From there, a structure gradually took shape that almost resembles a planetary system, with characters orbiting the central conceit like moons. For better or worse, the characters exist to support the framework of the story rather than to live as individuals on the page.
  • Liu’s imagination is dauntingly capacious, his narratives conceived on a scale that feels, at times, almost hallucinogenic. The time line of the trilogy spans 18,906,450 years, encompassing ancient Egypt, the Qin dynasty, the Byzantine Empire, the Cultural Revolution, the present, and a time eighteen million years in the future
  • The first book is set on Earth, though some of its scenes take place in virtual reality; by the end of the third book, the scope of the action is interstellar and annihilation unfolds across several dimensions. The London Review of Books has called the trilogy “one of the most ambitious works of science fiction ever written.”
  • Although physics furnishes the novels’ premises, it is politics that drives the plots. At every turn, the characters are forced to make brutal calculations in which moral absolutism is pitted against the greater good
  • In Liu’s fictional universe, idealism is fatal and kindness an exorbitant luxury. As one general says in the trilogy, “In a time of war, we can’t afford to be too scrupulous.” Indeed, it is usually when people do not play by the rules of Realpolitik that the most lives are lost.
  • “I know what you are thinking,” he told me with weary clarity. “What about individual liberty and freedom of governance?” He sighed, as if exhausted by a debate going on in his head. “But that’s not what Chinese people care about. For ordinary folks, it’s the cost of health care, real-estate prices, their children’s education. Not democracy.”
  • Liu closed his eyes for a long moment and then said quietly, “This is why I don’t like to talk about subjects like this. The truth is you don’t really—I mean, can’t truly—understand.”
  • Liu explained to me, the existing regime made the most sense for today’s China, because to change it would be to invite chaos. “If China were to transform into a democracy, it would be hell on earth,”
  • It was an opinion entirely consistent with his systems-level view of human societies, just as mine reflected a belief in democracy and individualism as principles to be upheld regardless of outcomes
  • “I cannot escape and leave behind reality, just like I cannot leave behind my shadow. Reality brands each of us with its indelible mark. Every era puts invisible shackles on those who have lived through it, and I can only dance in my chains.
  • Chinese people of his generation were lucky, he said. The changes they had seen were so huge that they now inhabited a world entirely different from that of their childhood. “China is a futuristic country,” he said. “I realized that the world around me became more and more like science fiction, and this process is speeding up.”
  • “We have statues of a few martyrs, but we never—We don’t memorialize those, the individuals.” He took off his glasses and blinked, peering into the wide expanse of green and concrete. “This is how we Chinese have always been,” he said. “When something happens, it passes, and time buries the stories.”

The trouble with atheists: a defence of faith | Books | The Guardian - 1 views

  • My daughter has just turned six. Some time over the next year or so, she will discover that her parents are weird. We're weird because we go to church.
  • This means as she gets older there'll be voices telling her what it means, getting louder and louder until by the time she's a teenager they'll be shouting right in her ear. It means that we believe in a load of bronze-age absurdities. That we fetishise pain and suffering. That we advocate wishy-washy niceness. That we're too stupid to understand the irrationality of our creeds. That we build absurdly complex intellectual structures on the marshmallow foundations of a fantasy. That we're savagely judgmental.
  • that's not the bad news. Those are the objections of people who care enough about religion to object to it. Or to rent a set of recreational objections from Richard Dawkins or Christopher Hitchens. As accusations, they may be a hodge-podge, but at least they assume there's a thing called religion which looms with enough definition and significance to be detested.
  • ...25 more annotations...
  • the really painful message our daughter will receive is that we're embarrassing. For most people who aren't New Atheists, or old atheists, and have no passion invested in the subject, either negative or positive, believers aren't weird because we're wicked. We're weird because we're inexplicable; because, when there's no necessity for it that anyone sensible can see, we've committed ourselves to a set of awkward and absurd attitudes that obtrude, that stick out against the background of modern life, and not in some important or respectworthy or principled way, either.
  • Believers are people who try to insert Jee-zus into conversations at parties; who put themselves down, with writhings of unease, for perfectly normal human behaviour; who are constantly trying to create a solemn hush that invites a fart, a hiccup, a bit of subversion. Believers are people who, on the rare occasions when you have to listen to them, like at a funeral or a wedding, seize the opportunity to pour the liquidised content of a primary-school nativity play into your earhole, apparently not noticing that childhood is over.
  • What goes on inside believers is mysterious. So far as it can be guessed at it appears to be a kind of anxious pretending, a kind of continual, nervous resistance to reality.
  • to me, it's belief that involves the most uncompromising attention to the nature of things of which you are capable. Belief demands that you dispense with illusion after illusion, while contemporary common sense requires continual, fluffy pretending – pretending that might as well be systematic, it's so thoroughly incentivised by our culture.
  • The atheist bus says: "There's probably no God. So stop worrying and enjoy your life."
  • the word that offends against realism here is "enjoy". I'm sorry – enjoy your life?
  • If you based your knowledge of the human species exclusively on adverts, you'd think that the normal condition of humanity was to be a good-looking single person between 20 and 35, with excellent muscle-definition and/or an excellent figure, and a large disposable income. And you'd think the same thing if you got your information exclusively from the atheist bus
  • The implication of the bus slogan is that enjoyment would be your natural state if you weren't being "worried" by us believers and our hellfire preaching. Take away the malignant threat of God-talk, and you would revert to continuous pleasure
  • What's so wrong with this, apart from it being total bollocks? Well, in the first place, that it buys a bill of goods, sight unseen, from modern marketing. Given that human life isn't and can't be made up of enjoyment, it is in effect accepting a picture of human life in which those pieces of living where easy enjoyment is more likely become the only pieces that are visible.
  • But then, like every human being, I am not in the habit of entertaining only those emotions I can prove. I'd be an unrecognisable oddity if I did. Emotions can certainly be misleading: they can fool you into believing stuff that is definitely, demonstrably untrue. Yet emotions are also our indispensable tool for navigating, for feeling our way through, the much larger domain of stuff that isn't susceptible to proof or disproof, that isn't checkable against the physical universe. We dream, hope, wonder, sorrow, rage, grieve, delight, surmise, joke, detest; we form such unprovable conjectures as novels or clarinet concertos; we imagine. And religion is just a part of that, in one sense. It's just one form of imagining, absolutely functional, absolutely human-normal. It would seem perverse, on the face of it, to propose that this one particular manifestation of imagining should be treated as outrageous, should be excised if (which is doubtful) we can manage it.
  • suppose, as the atheist bus goes by, you are povertystricken, or desperate for a job, or a drug addict, or social services have just taken away your child. The bus tells you that there's probably no God so you should stop worrying and enjoy your life, and now the slogan is not just bitterly inappropriate in mood. What it means, if it's true, is that anyone who isn't enjoying themselves is entirely on their own. What the bus says is: there's no help coming.
  • Enjoyment is great. The more enjoyment the better. But enjoyment is one emotion. To say that life is to be enjoyed (just enjoyed) is like saying that mountains should only have summits, or that all colours should be purple, or that all plays should be by Shakespeare. This really is a bizarre category error.
  • A consolation you could believe in would be one that wasn't in danger of popping like a soap bubble on contact with the ordinary truths about us. A consolation you could trust would be one that acknowledged the difficult stuff rather than being in flight from it, and then found you grounds for hope in spite of it, or even because of it
  • The novelist Richard Powers has written that the Clarinet Concerto sounds the way mercy would sound, and that's exactly how I experienced it in 1997. Mercy, though, is one of those words that now requires definition. It does not only mean some tyrant's capacity to suspend a punishment he has himself inflicted. It can mean – and does mean in this case – getting something kind instead of the sensible consequences of an action, or as well as the sensible consequences of an action.
  • from outside, belief looks like a series of ideas about the nature of the universe for which a truth-claim is being made, a set of propositions that you sign up to; and when actual believers don't talk about their belief in this way, it looks like slipperiness, like a maddening evasion of the issue.
  • I am a fairly orthodox Christian. Every Sunday I say and do my best to mean the whole of the Creed, which is a series of propositions. But it is still a mistake to suppose that it is assent to the propositions that makes you a believer. It is the feelings that are primary. I assent to the ideas because I have the feelings; I don't have the feelings because I've assented to the ideas.
  • what I felt listening to Mozart in 1997 is not some wishy-washy metaphor for an idea I believe in, and it's not a front behind which the real business of belief is going on: it's the thing itself. My belief is made of, built up from, sustained by, emotions like that. That's what makes it real.
  • I think that Mozart, two centuries earlier, had succeeded in creating a beautiful and accurate report of an aspect of reality. I think that the reason reality is that way – that it is in some ultimate sense merciful as well as being a set of physical processes all running along on their own without hope of appeal, all the way up from quantum mechanics to the relative velocity of galaxies by way of "blundering, low and horridly cruel" biology (Darwin) – is that the universe is sustained by a continual and infinitely patient act of love. I think that love keeps it in being.
  • That's what I think. But it's all secondary. It all comes limping along behind my emotional assurance that there was mercy, and I felt it. And so the argument about whether the ideas are true or not, which is the argument that people mostly expect to have about religion, is also secondary for me.
  • No, I can't prove it. I don't know that any of it is true. I don't know if there's a God. (And neither do you, and neither does Professor Dawkins, and neither does anybody. It isn't the kind of thing you can know. It isn't a knowable item.)
  • let's be clear about the emotional logic of the bus's message. It amounts to a denial of hope or consolation on any but the most chirpy, squeaky, bubble-gummy reading of the human situation
  • It's got itself established in our culture, relatively recently, that the emotions involved in religious belief must be different from the ones involved in all the other kinds of continuous imagining, hoping, dreaming, and so on, that humans do. These emotions must be alien, freakish, sad, embarrassing, humiliating, immature, pathetic. These emotions must be quite separate from commonsensical us. But they aren't
  • The emotions that sustain religious belief are all, in fact, deeply ordinary and deeply recognisable to anybody who has ever made their way across the common ground of human experience as an adult.
  • It's just that the emotions in question are rarely talked about apart from their rationalisation into ideas. This is what I have tried to do in my new book, Unapologetic.
  • You can easily look up what Christians believe in. You can read any number of defences of Christian ideas. This, however, is a defence of Christian emotions – of their intelligibility, of their grown-up dignity.

The Lasting Lessons of John Conway's Game of Life - The New York Times - 0 views

  • “Because of its analogies with the rise, fall and alterations of a society of living organisms, it belongs to a growing class of what are called ‘simulation games,’” Mr. Gardner wrote when he introduced Life to the world 50 years ago with his October 1970 column.
  • The Game of Life motivated the use of cellular automata in the rich field of complexity science, with simulations modeling everything from ants to traffic, clouds to galaxies. More trivially, the game attracted a cult of “Lifenthusiasts,” programmers who spent a lot of time hacking Life — that is, constructing patterns in hopes of spotting new Life-forms.
  • The tree of Life also includes oscillators, such as the blinker, and spaceships of various sizes (the glider being the smallest).
  • ...24 more annotations...
  • Patterns that didn’t change one generation to the next, Dr. Conway called still lifes — such as the four-celled block, the six-celled beehive or the eight-celled pond. Patterns that took a long time to stabilize, he called methuselahs.
  • The second thing Life shows us is something that Darwin hit upon when he was looking at Life, the organic version. Complexity arises from simplicity!
  • I first encountered Life at the Exploratorium in San Francisco in 1978. I was hooked immediately by the thing that has always hooked me — watching complexity arise out of simplicity.
  • Life shows you two things. The first is sensitivity to initial conditions. A tiny change in the rules can produce a huge difference in the output, ranging from complete destruction (no dots) through stasis (a frozen pattern) to patterns that keep changing as they unfold.
  • Life shows us complex virtual “organisms” arising out of the interaction of a few simple rules — so goodbye “Intelligent Design.”
  • I’ve wondered for decades what one could learn from all that Life hacking. I recently realized it’s a great place to try to develop “meta-engineering” — to see if there are general principles that govern the advance of engineering and help us predict the overall future trajectory of technology.
  • Melanie Mitchell— Professor of complexity, Santa Fe Institute
  • Given that Conway’s proof that the Game of Life can be made to simulate a Universal Computer — that is, it could be “programmed” to carry out any computation that a traditional computer can do — the extremely simple rules can give rise to the most complex and most unpredictable behavior possible. This means that there are certain properties of the Game of Life that can never be predicted, even in principle!
  • I use the Game of Life to make vivid for my students the ideas of determinism, higher-order patterns and information. One of its great features is that nothing is hidden; there are no black boxes in Life, so you know from the outset that anything that you can get to happen in the Life world is completely unmysterious and explicable in terms of a very large number of simple steps by small items.
  • In Thomas Pynchon’s novel “Gravity’s Rainbow,” a character says, “But you had taken on a greater and more harmful illusion. The illusion of control. That A could do B. But that was false. Completely. No one can do. Things only happen.”This is compelling but wrong, and Life is a great way of showing this.
  • In Life, we might say, things only happen at the pixel level; nothing controls anything, nothing does anything. But that doesn’t mean that there is no such thing as action, as control; it means that these are higher-level phenomena composed (entirely, with no magic) from things that only happen.
  • Stephen Wolfram— Scientist and C.E.O., Wolfram Research
  • Brian Eno— Musician, London
  • Bert Chan— Artificial-life researcher and creator of the continuous cellular automaton “Lenia,” Hong Kong
  • it did have a big impact on beginner programmers, like me in the 90s, giving them a sense of wonder and a kind of confidence that some easy-to-code math models can produce complex and beautiful results. It’s like a starter kit for future software engineers and hackers, together with Mandelbrot Set, Lorenz Attractor, et cetera.
  • if we think about our everyday life, about corporations and governments, the cultural and technical infrastructures humans built for thousands of years, they are not unlike the incredible machines that are engineered in Life.
  • In normal times, they are stable and we can keep building stuff one component upon another, but in harder times like this pandemic or a new Cold War, we need something that is more resilient and can prepare for the unpreparable. That would need changes in our “rules of life,” which we take for granted.
  • Rudy Rucker— Mathematician and author of “Ware Tetralogy,” Los Gatos, Calif.
  • That’s what chaos is about. The Game of Life, or a kinky dynamical system like a pair of pendulums, or a candle flame, or an ocean wave, or the growth of a plant — they aren’t readily predictable. But they are not random. They do obey laws, and there are certain kinds of patterns — chaotic attractors — that they tend to produce. But again, unpredictable is not random. An important and subtle distinction which changed my whole view of the world.
  • William Poundstone— Author of “The Recursive Universe: Cosmic Complexity and the Limits of Scientific Knowledge,” Los Angeles, Calif.
  • The Game of Life’s pulsing, pyrotechnic constellations are classic examples of emergent phenomena, introduced decades before that adjective became a buzzword.
  • Fifty years later, the misfortunes of 2020 are the stuff of memes. The biggest challenges facing us today are emergent: viruses leaping from species to species; the abrupt onset of wildfires and tropical storms as a consequence of a small rise in temperature; economies in which billions of free transactions lead to staggering concentrations of wealth; an internet that becomes more fraught with hazard each year
  • Looming behind it all is our collective vision of an artificial intelligence-fueled future that is certain to come with surprises, not all of them pleasant.
  • The name Conway chose — the Game of Life — frames his invention as a metaphor. But I’m not sure that even he anticipated how relevant Life would become, and that in 50 years we’d all be playing an emergent game of life and death.

A Tantalizing Signal From the Early Universe - The Atlantic - 0 views

  • Near the beginning, not long after the Big Bang, the universe was a cold and dark place swirling with invisible gas, mostly hydrogen and helium. Over millions of years, gravity pulled some of this primordial gas into pockets. The pockets eventually became so dense they collapsed under their own weight and ignited, flooding the darkness with ultraviolet radiation. These were the very first stars in the universe, flashing into existence like popcorn kernels unfurling in the hot oil of an empty pan.
  • Everything flowed from this cosmic dawn. The first stars illuminated the universe, collapsed into the black holes that keep galaxies together, and produced the heavy elements that would make planets and moons and the human beings that evolved to gaze upon it all.
  • This epoch in our cosmic history has long fascinated scientists. They hoped that someday, using technology that was calibrated just right, they could detect faint signals from that moment. Now, they think they’ve done it.
  • ...4 more annotations...
  • Astronomers said Wednesday they have found, for the first time, evidence of the earliest stars.
  • The nature of this signal suggests a new estimate for when the first stars emerged: about 180 million years after the Big Bang, slightly earlier than many scientists expected, but still within the expectations of theoretical models.
  • The nature of the radio waves Bowman and his colleagues detected mostly matches theoretical predictions, but not everything lines up. When they tuned their instrument to listen to the frequency for hydrogen gas that models predicted, they didn’t hear anything. When they decided to search in a lower range, they got it. But the signal they found was stronger than expected. That meant that the hydrogen gas in the early universe was much much colder—perhaps nearly twice as cold—than previously estimated.
  • Bowman says other teams around the world have been working to build and design instruments to detect this signal from the early universe, and he expects they should be able to confirm the results in the coming months.

A cold Neptune and two super-Earths are among newly found exoplanets around nearby star... - 0 views

  • Five exoplanets and eight planet candidates have been found around nearby stars, including a "cold Neptune" and two super-Earths that are potentially habitable, according to a new study. The two super-Earths, GJ180d and GJ229Ac, were found around small red dwarf stars that are 19 and 40 light-years away from our sun, while the cold Neptune was found around a similar star that's 29.5 light-years away.
  • "GJ 433 d is the nearest, widest and coldest Neptune-like planet ever detected," said Fabo Feng, lead study author and astronomer at the Carnegie Institution for Science. A multitude of exoplanets, especially terrestrial planets like Earth, have been found around red dwarf stars. They're smaller and cooler than our sun, and they're the most common star in our galaxy. Exoplanets tend to orbit closer to these stars and still be within the star's habitable zone, or the perfect distance for the planet to be temperate and potentially host liquid water on their surfaces.
  • Meanwhile, the other super-Earth, GJ229Ac, is the nearest temperate super-Earth in a system where the host star is also orbited by a brown dwarf. Brown dwarfs are known as failed stars that can't sustain the hydrogen fusion needed to power them

  • "We eventually want to build a map of all of the planets orbiting the nearest stars to our own solar system, especially those that are potentially habitable," said Jeffrey Crane, study co-author and astronomer at the Carnegie Institution for Science.

Mihaly Csikszentmihalyi, the Father of 'Flow,' Dies at 87 - The New York Times - 0 views

  • Flow became an important element of positive psychology, a movement started in the early 2000s by Dr. Csikszentmihalyi and Martin Seligman, a psychologist at the University of Pennsylvania. It focused not on the pathologies of the human mind but its everyday experiences.
  • “Csikszentmihalyi was such a leader in our field it’s hard to do his contributions justice,” Laurie Santos, a professor of psychology at Yale, wrote in an email. “I think in a world where it’s become harder and harder to focus, his work on flow has become even more important.”
  • Dr. Csikszentmihalyi did not just explain “flow”; he offered a pointed critique of why so many people fail to achieve it. He cited countless studies showing that most people prefer meaningful work over mindless downtime, but argued that Americans in particular had been conditioned to hate their jobs and love passive relaxation.
  • ...3 more annotations...
  • He blamed television, above all, for the decline in hobbies, avocations and lifelong education — activities that blend aspects of work and play and, he said, offer the best opportunity for flow and, through it, happiness.
  • Some critics said his finger pointing smacked of snobbery, to which he had a response: “If holding that everyone should have a chance to get the highest quality of experience is an elitist notion, so be it,” he wrote in a guest essay for The New York Times in 1993. “It is better than resigning oneself to a life of mindless entertainment.”
  • “We can’t afford to become trapped within ourselves, our jobs, and religions, and lose sight of the entire tapestry of life,” he said in a 1995 interview with Omni magazine. “When the self loses itself in a transcendent purpose — whether to write great poetry, craft beautiful furniture, understand the motions of galaxies, or help children be happier — the self becomes largely invulnerable to the fears and setbacks of ordinary existence.”

  • “Reminiscence” is a great illustration of how strangely passive and defeatist an industry full of Prius early adopters has been about the biggest challenge of our time.
  • Hollywood’s reliance on big-budget action movies plays a role in its inability to address climate change effectively. In an industry reliant on chases, special effects and disasters, even ostensible “issue movies” get wedged into the same template.
  • these movies share at least one thing: pessimism. Climate change will be catastrophic — as will be many human responses to it.

  • Even movies that explore adaptive responses to climate change make glum assumptions. In Christopher Nolan’s “Interstellar,” humanity’s future lies on a far distant planet; Earth is unsalvageable. James Cameron’s first “Avatar” movie imagines that resource crises will drive humanity to galaxy-wide pillage.
  • In Robinson’s telling, climate change will upend our lives, but we all have something to contribute to the response to this radical reordering.
  • The idea that pop culture can tell these stories creatively and dynamically is not merely speculative.
  • “The Ministry for the Future” novelist Kim Stanley Robinson has spent decades creatively imagining how humanity might respond to harsh conditions, whether that means Mars and the asteroid belt or a drowned New York City.
  • If activists, be they filmmakers or politicians, want to persuade the public to adopt new behaviors, or even to do more than simply despair, they need to give the ordinary person a vision for what to do.

Musk, SBF, and the Myth of Smug, Castle-Building Nerds - 0 views

  • Experts in content moderation suggested that Musk’s actual policies lacked any coherence and, if implemented, would have all kinds of unintended consequences. That has happened with verification. Almost every decision he makes is an unforced error made with extreme confidence in front of a growing audience of people who already know he has messed up, and is supported by a network of sycophants and blind followers who refuse to see or tell him that he’s messing up. The dynamic is … very Trumpy!
  • As with the former president, it can be hard at times for people to believe or accept that our systems are so broken that a guy who is clearly this inept can also be put in charge of something so important. A common pundit claim before Donald Trump got into the White House was that the gravity of the job and prestige of the office might humble or chasten him.
  • The same seems true for Musk. Even people skeptical of Musk’s behavior pointed to his past companies as predictors of future success. He’s rich. He does smart-people stuff. The rockets land pointy-side up!

  • Time and again, we learned there was never a grand plan or big ideas—just weapons-grade ego, incompetence, thin skin, and prejudice against those who don’t revere him.
  • Despite all the incredible, damning reporting coming out of Twitter and all of Musk’s very public mistakes, many people still refuse to believe—even if they detest him—that he is simply incompetent.
  • What is amazing about the current moment is that, despite how ridiculous it all feels, a fundamental tenet of reality and logic appears to be holding true: If you don’t know what you’re doing or don’t really care, you’ll run the thing you’re in charge of into the ground, and people will notice.
  • And so the moment feels too dumb and too on the nose to be real and yet also very real—kind of like all of reality in 2022.
  • I don’t really know where any of this will lead, but one interesting possibility is that Musk gets increasingly reactionary and trollish in his politics and stewardship of Twitter.
  • Leaving the politics aside, from a basic customer-service standpoint this is generally an ill-advised way for the owner of a company to treat an elected official when that elected official wishes to know why your service has failed them. The reason it is ill-advised is because then the elected official could tweet something like what Senator Markey tweeted on Sunday: “One of your companies is under an FTC consent decree. Auto safety watchdog NHTSA is investigating another for killing people. And you’re spending your time picking fights online. Fix your companies. Or Congress will.”
  • It seems clear that Musk, like any dedicated social-media poster, thrives on validation, so it makes sense that, as he continues to dismantle his own mystique as an innovator, he might look for adoration elsewhere
  • Recent history has shown that, for a specific audience, owning the libs frees a person from having to care about competency or outcome of their actions. Just anger the right people and you’re good, even if you’re terrible at your job. This won’t help Twitter’s financial situation, which seems bleak, but it’s … something!
  • Bankman-Fried, the archetype, appealed to people for all kinds of reasons. His narrative as a philanthropist, and a smart rationalist, and a stone-cold weirdo was something people wanted to buy into because, generally, people love weirdos who don’t conform to systems and then find clever ways to work around them and become wildly successful as a result.
  • Bankman-Fried was a way that a lot of people could access and maybe obliquely understand what was going on in crypto. They may not have understood what FTX did, but they could grasp a nerd trying to leverage a system in order to do good in the world and advance progressive politics. In that sense, Bankman-Fried is easy to root for and exciting to cover. His origin story and narrative become more important than the particulars of what he may or may not be doing.
  • the past few weeks have been yet another reminder that the smug-nerd-genius narrative may sell magazines, and it certainly raises venture funding, but the visionary founder is, first and foremost, a marketing product, not a reality. It’s a myth that perpetuates itself. Once branded a visionary, the founder can use the narrative to raise money and generate a formidable net worth, and then the financial success becomes its own résumé. But none of it is real.
  • Adversarial journalism ideally questions and probes power. If it is trained on technology companies and their founders, it is because they either wield that power or have the potential to do so. It is, perhaps unintuitively, a form of respect for their influence and potential to disrupt. But that’s not what these founders want.
  • even if all tech coverage had been totally flawless, Silicon Valley would have rejected adversarial tech journalism because most of its players do not actually want the responsibility that comes with their potential power. They want only to embody the myth and reap the benefits. They want the narrative, which is focused on origins, ambitions, ethos, and marketing, and less on the externalities and outcomes.
  • Looking at Musk and Bankman-Fried, it would appear that the tech visionaries mostly get their way. For all the complaints of awful, negative coverage and biased reporting, people still want to cheer for and give money to the “‘smug nerds building castles in the sky.’” Though they vary wildly right now in magnitude, their wounds are self-inflicted—and, perhaps, the result of believing their own hype.
  • That’s because, almost always, the smug-nerd-genius narrative is a trap. It’s one that people fall into because they need to believe that somebody out there is so brilliant, they can see the future, or that they have some greater, more holistic understanding of the world (or that such an understanding is possible)
  • It’s not unlike a conspiracy theory in that way. The smug-nerd-genius narrative helps take the complexity of the world and make it more manageable.
  • Putting your faith in a space billionaire or a crypto wunderkind isn’t just sad fanboydom; it is also a way for people to outsource their brain to somebody else who, they believe, can see what they can’t
  • the smug nerd genius is exceedingly rare, and, even when they’re not outed as a fraud or a dilettante, they can be assholes or flawed like anyone else. There aren’t shortcuts for making sense of the world, and anyone who is selling themselves that way or buying into that narrative about them should read to us as a giant red flag.

The Israel-Hamas War Shows Just How Broken Social Media Has Become - The Atlantic - 0 views

  • major social platforms have grown less and less relevant in the past year. In response, some users have left for smaller competitors such as Bluesky or Mastodon. Some have simply left. The internet has never felt more dense, yet there seem to be fewer reliable avenues to find a signal in all the noise. One-stop information destinations such as Facebook or Twitter are a thing of the past. The global town square—once the aspirational destination that social-media platforms would offer to all of us—lies in ruins, its architecture choked by the vines and tangled vegetation of a wild informational jungle
  • Musk has turned X into a deepfake version of Twitter—a facsimile of the once-useful social network, altered just enough so as to be disorienting, even terrifying.
  • At the same time, Facebook’s user base began to erode, and the company’s transparency reports revealed that the most popular content circulating on the platform was little more than viral garbage—a vast wasteland of CBD promotional content and foreign tabloid clickbait.
  • ...4 more annotations...
  • What’s left, across all platforms, is fragmented. News and punditry are everywhere online, but audiences are siloed; podcasts are more popular than ever, and millions of younger people online have turned to influencers and creators on Instagram and especially TikTok as trusted sources of news.
  • Social media, especially Twitter, has sometimes been an incredible news-gathering tool; it has also been terrible and inefficient, a game of do your own research that involves batting away bullshit and parsing half truths, hyperbole, outright lies, and invaluable context from experts on the fly. Social media’s greatest strength is thus its original sin: These sites are excellent at making you feel connected and informed, frequently at the expense of actually being informed.
  • At the center of these pleas for a Twitter alternative is a feeling that a fundamental promise has been broken. In exchange for our time, our data, and even our well-being, we uploaded our most important conversations onto platforms designed for viral advertising—all under the implicit understanding that social media could provide an unparalleled window to the world.
  • What comes next is impossible to anticipate, but it’s worth considering the possibility that the centrality of social media as we’ve known it for the past 15 years has come to an end—that this particular window to the world is being slammed shut.

Elon Musk Doesn't Want Transparency on Twitter - The Atlantic - 0 views

  • , the Twitter Files do what technology critics have long done: point out a mostly intractable problem that is at the heart of our societal decision to outsource broad swaths of our political discourse and news consumption to corporate platforms whose infrastructure and design were made for viral advertising.
  • The trolling is paramount. When former Facebook CSO and Stanford Internet Observatory leader Alex Stamos asked whether Musk would consider implementing his detailed plan for “a trustworthy, neutral platform for political conversations around the world,” Musk responded, “You operate a propaganda platform.” Musk doesn’t appear to want to substantively engage on policy issues: He wants to be aggrieved.
  • it’s possible that a shred of good could come from this ordeal. Musk says Twitter is working on a feature that will allow users to see if they’ve been de-amplified, and appeal. If it comes to pass, perhaps such an initiative could give users a better understanding of their place in the moderation process. Great!

Opinion | Tesla suffers from the boss's addiction to Twitter - The Washington Post - 0 views

  • For some perspective on what’s happening with Elon Musk and Twitter, I suggest spending a few minutes familiarizing yourself with one of Twitter’s sillier episodes from the past, a fight that erupted almost a year ago between the “shape rotators” of Silicon Valley and the “wordcels” (aspersion intended) of journalism and related professions. Many of the combatants were, at first, merely fighting over which group should have higher social status (theirs), but the episode also highlighted real divisions between West Coast and East — math and verbal, free-speech culture and safety culture, people who make things happen and people who talk about them afterward.
  • For years now, conflict between the two groups has been boiling over onto social media, into courtrooms and onto the pages of major news outlets. Team Shape Rotator believes Team Wordcel is parasitic and dangerous, ballyragging institutions into curbing both free speech and innovation in the name of safety. Team “Stop calling me a Wordcel” sees its opponents as self-centered and reckless, disrupting and mean-meming their way toward some vaguely imagined doom.
  • his audacity seems to be backfiring, as of course did Napoleon’s eventually.
  • ...5 more annotations...
  • You can think of Musk’s acquisition of Twitter as the latest sortie, a takeover of the ultimate wordcel site by the world’s most successful shape rotator.
  • more likely, he fell prey to a different delusion, one in which the shape rotators and the wordcels are united: thinking of Twitter in terms of words and arguments, as a “digital public square” where vital questions are hashed out. It is that, sometimes, but that’s not what it’s designed for. It’s designed to maximize engagement, which is to say, it’s an addiction machine for the highly verbal.
  • Both groups theoretically understand what the machine is doing — the wordcels write endless articles about bad algorithms, and the shape rotators build them. But both nonetheless talk as though they’re saving the world even as they compulsively follow the programming. The shape rotators bait the wordcels because that’s what makes the machine spit out more rewarding likes and retweets. We wordcels return the favor for the same reason.
  • Musk could theoretically rework Twitter’s architecture to downrank provocation and make it less addictive. But of course, that would make it a less profitable business
  • More to the point, the reason he bought it is that he, like his critics, is hooked on it the way it is now. Unfortunately for Tesla shareholders, Musk has now put himself in the position of a dealer who can spend all day getting high on his own supply.
