The Habits of Light: A Celebration of Pioneering Astronomer Henrietta Leavitt, Whose Ca... - 0 views

  • “Nothing is fixed. All is in flux,” physicist Alan Lightman wrote in his soaring meditation on how to live with our longing for absolutes in a relative universe, reminding us that all the physical evidence gleaned through millennia of scientific inquiry indicates the inherent inconstancy of the cosmos.
  • This awareness, so unnerving against the backdrop of our irrepressible yearning for constancy and permanence, was first unlatched when the ancients began suspecting that the Earth, rather than being the static center of the heavens it was long thought to be, is in motion, right beneath our feet. But it took millennia for the most disorienting evidence of inconstancy to dawn — the discovery that the universe itself is in flux, constantly expanding, growing thinner and thinner as stars grow farther and farther apart.
  • If the universe is constantly expanding, to trace it backward along the arrow of time is to imagine it smaller and smaller, all the way down to the seeming nothingness that banged into the somethingness within which everything exists.

Out-Of-Body Experiences: Mine Is Finally Explained | Psychology Today - 0 views

  • Sleep deprivation had disturbed my vestibular system, making me feel drifting or floating, and had especially interfered with my right TPJ and with it my body schema (Chee & Chua 2007, Quarck et al 2006). Nearly four hours of holding out my arm for the Ouija board had confused my body schema even more. My attention kept wandering and my short term memory was reduced by cannabis (Earleywine 2002).
  • With my hyperexcitable cortex (Braithwaite et al 2013) already disinhibited by the combination of sleep deprivation and cannabis, it went into random firing, producing an illusory central light and the form constants of spirals and tunnels (Cowan 1982). Disinhibited motion detectors produced illusory movement and as the light grew bigger I seemed to move towards it
  • My auditory cortex was similarly hyperactive, producing random low-frequency repetitive sounds that drowned out the music. It sounded to me like the pounding of horses’ hooves. I was galloping fast down the tunnel towards the light.

  • ‘Where are you, Sue?’ I was brought up short. I tried to picture my own body and where it really was, but my prefrontal cortex was deactivated as the brain hovered on the edge of sleep (Muzur et al 2002). With my TPJ disturbed it was impossible to combine a body schema with vestibular and sensory input to give a firm sense of an embodied self (Blanke et al 2002).
  • The roofs, gutters and chimneys I saw were just as I imagined them, not as they were. So were the cities, lakes, oceans and islands I saw. I laughed at the vivid ‘star-shaped island with a hundred trees’, believing it was a thought-form in the astral plane (Besent 1896, Findlay 1931) because that was the only theory I knew.
  • I was too tired to do more than glimpse this new vastness. In exhaustion, I seemed to face a choice, to stay in this marvelous, right-seeming, perfect state, or return to ordinary life. The choice made itself and the struggle began. After more than two hours of serious disturbance, this brain took some time to reinstate both body schema and self-image and even then confused my own body with others. When I opened my eyes I felt and saw greyish body-shapes around the others as well as myself; displaced body schemas that gradually faded until I was (more or less) back to normal. Yet nothing was ever quite the same again.”
  • But that’s the joy of doing science at all. I have not, in these posts, covered the tunnel experience, the silver cord and several other features more commonly found during near-death experiences, but I may return to them in future. For now I hope you have enjoyed this series of OBE stories.

God, Mathematics and Psychology | Psychology Today - 0 views

  • This is a Epicurean (341–270 BC) belief that the gods are too busy to deal with the day-to-day running of the universe but they set it in motion using mathematics.
  • The same is true for language, art, music and other “Third World” constructs—these are incrementally evolving systems and form one of Karl Popper’s ontological tools (Carr, 1977).

How to Talk About Climate Change Across the Political Divide | The New Yorker - 0 views

  • “It was really moving to Texas that set me on this path of figuring out how to communicate about climate change,” she told me. “I was the only climate scientist within two hundred miles.”
  • She records the questions she is asked afterward, using an app, and the two most frequent are: “What gives you hope?” and “How do I talk to my [blank] about climate change?
  • In the late nineties, a Gallup poll found that forty-six per cent of Democrats and forty-seven per cent of Republicans agreed that the effects of global warming had already begun.
  • ...30 more annotations...
  • In her new book, “Saving Us,” which comes out in September, Hayhoe sets out to answer these questions. Chapter by chapter, she lays out effective strategies for communicating about the urgency of climate change across America’s political divide.
  • She breaks out categories—originally defined by her colleague Anthony Leiserowitz, at the Yale Program on Climate Change Communication, and other researchers—of attitudes toward global warming: alarmed, concerned, cautious, disengaged, and doubtful. Only the remaining eight per cent of Americans fall into the final category, dismissive.
  • In the past decade, though, as the scope of the crisis became clear, Democrats began pressing for policies to cut U.S. reliance on fossil fuels, and Republicans were reluctant to commit. Energy companies stepped into the stalemate and began aggressively lobbying politicians, and injecting doubt into the public discourse, to stop such policies from taking effect. “Industry swung into motion to activate the political system in their favor,” Hayhoe said.
  • “In a study of fifty-six countries, researchers found people’s opinions on climate change to be most strongly correlated not with education and knowledge, but rather with ‘values, ideologies, worldviews and political orientation,’ ”
  • One salient problem is an aspect of human behavior that researchers have termed “solution aversion.” Solving the climate crisis will require ending our reliance on fossil fuels, which people believe would involve major sacrifice.
  • “If there’s a problem and we’re not going to fix it, then that makes us bad people,” Hayhoe said. “No one wants to be a bad person.” So instead people are happy to seize on excuses not to take action.
  • Most are what she calls “science-y sounding objections, and, in the U.S., religious-y sounding objections.”
  • Hayhoe often hears that the Earth has always heated and cooled according to its own intrinsic cycle, or that God, not humanity, controls the fate of the planet. These objections can then harden into aspects of our political identity.
  • Hayhoe eschews the term “climate denier,” saying that she has “seen it applied all too often to shut down discussion rather than encourage it.”
  • So much of this is not about the facts,” Leiserowitz told me later. “It’s about trusting the person the facts come from.”
  • research has shown her that dismissives are nearly impossible to influence. They are also few enough that it should be possible to build political will around fighting climate change by focussing on others.
  • “It’s not about the loudest voices,” Hayhoe told me. “It’s about everyone else who doesn’t understand why climate change matters or what they can do about it.”
  • Leiserowitz told me. His work has revealed, for example, that conversations about the climate tend to be more effective if both speakers share a core value or an aspect of their identity. The most effective climate communicators to conservatives are often people of faith, members of the military, and Republicans who are nevertheless committed to the climate.
  • “That’s why it’s so important to seek out like-minded groups: winter athletes, parents, fellow birders or Rotarians, or people who share our faith.”
  • There is a long history within evangelicalism of advocating “creation care,” the belief that God charged humanity with caring for the earth. The Evangelical Environmental Network, which Hayhoe advises, argues that evangelicals should follow a “Biblical mandate to care for creation,”
  • Hayhoe believes that emphasizing the care of plants and animals is less effective than highlighting the potential dangers for our fellow human beings. “It’s not about saving the planet—it’s about saving us,”
  • One of her communication strategies is to talk to people about their own observations, which help them connect the realities of their lives to the abstraction of climate change.
  • With farmers, Hayhoe avoids using the term “climate change,” since the phenomenon is frequently seen as a liberal hoax. “We use the words ‘climate variability’ and ‘long-term trends,’ ” she said.
  • Scott’s work served another purpose. By showing success with his climate-conscious farming techniques, he might persuade other farmers to join in, potentially becoming the center of what Hayhoe calls a cluster. “I preach to my friends about how well it’s doing,” he said.
  • I don’t accost people in diners,” she wrote me, later. “I wait until they come to me.”
  • “As recently as 2008, former speaker of the house Newt Gingrich, a Republican, and current House speaker Nancy Pelosi, a Democrat, cozied up on a love seat in front of the U.S. Capitol to film a commercial about climate change,”
  • She then directed the conversation to Republican-led free market initiatives to combat climate change by putting a price on carbon emissions. Companies passed their costs onto the rest of us by putting the carbon into the atmosphere, she told Dale, “but what if they had to pay for it? What if, when someone’s house burned down because of a forest fire, the companies making money from selling carbon had to pay a homeowner back?” Dale responded, “Well, I’m in favor of that.”
  • “It’s so important to educate kids about what’s going on, not to frighten them but to show them they can have a hand in solutions.”
  • Through the years, she’s developed a system to manage trolls. “It’s been trial and error, error, error,” she said. She now responds once, offering a link to resources.
  • Most fire back with gendered insults, often plays on her last name, after which she blocks the sender.
  • ayhoe doesn’t urge guilt on her listeners. She only urges that we change our trajectory. “That’s all repentance means,” she said. “To turn.”
  • the most important aspect of fighting climate change is pushing for policies that will cut our reliance on fossil fuels. She urges the alarmed to get involved in politics, beginning with lobbying politicians at the local and state level.
  • she’d come across a book, “Scientists as Prophets: A Rhetorical Genealogy,” that examined the role of prophets in society, beginning with the oracle at Delphi, stretching through the Old Testament, and culminating in the work of modern-day scientists.

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.”

Before Kyle Rittenhouse's Murder Trial, a Debate Over Terms Like 'Victim' - The New Yor... - 0 views

  • A judge’s decision that the word “victim” generally could not be used in court to refer to the people shot by Kyle Rittenhouse after protests in Kenosha, Wis., last year drew widespread attention and outrage this week.
  • Mr. Rittenhouse, who has been charged with six criminal counts, including first-degree reckless homicide, first-degree intentional homicide and attempted first-degree intentional homicide in the deaths of two men and the wounding of another, is expected to argue that he fired his gun because he feared for his life.
  • Prosecutors say he was a violent vigilante who illegally possessed the rifle and whose actions resulted in chaos and bloodshed.

  • This week, as Judge Schroeder ruled on a motion by the prosecution, he also said that he would allow the terms “looters” and “rioters” to be used to refer to the men who were shot
  • The experts said the term “victim” can appear prejudicial in a court of law, heavily influencing a jury by presupposing which people have been wronged.

  • Prosecutors have repeatedly tried to introduce evidence of Mr. Rittenhouse’s associations with the far-right Proud Boys, as well as a cellphone video taken weeks before the shootings in Kenosha in which Mr. Rittenhouse suggested that he wished he had his rifle so he could shoot men leaving a pharmacy. The judge did not allow either as evidence for trial.
  • Thomas Binger, a prosecutor, argued that the judge was creating a “double standard” and said that the words he sought to have prohibited — relating to rioting and other damage — were “as loaded, if not more loaded, than the term ‘victim.’

Opinion | The Book That Explains Our Cultural Stagnation - The New York Times - 0 views

  • The best explanation I’ve read for our current cultural malaise comes at the end of W. David Marx’s forthcoming “Status and Culture: How Our Desire for Social Rank Creates Taste, Identity, Art, Fashion, and Constant Change,” a book that is not at all boring and that subtly altered how I see the world.
  • Marx posits cultural evolution as a sort of perpetual motion machine driven by people’s desire to ascend the social hierarchy. Artists innovate to gain status, and people unconsciously adjust their tastes to either signal their status tier or move up to a new one.
  • “Status struggles fuel cultural creativity in three important realms: competition between socioeconomic classes, the formation of subcultures and countercultures, and artists’ internecine battles.”
  • ...8 more annotations...
  • avant-garde composer John Cage. When Cage presented his discordant orchestral piece “Atlas Eclipticalis” at Lincoln Center in 1964, many patrons walked out. Members of the orchestra hissed at Cage when he took his bow; a few even smashed his electronic equipment. But Cage’s work inspired other artists, leading “historians and museum curators to embrace him as a crucial figure in the development of postmodern art,” which in turn led audiences to pay respectful attention to his work
  • “There was a virtuous cycle for Cage: His originality, mystery and influence provided him artist status; this encouraged serious institutions to explore his work; the frequent engagement with his work imbued Cage with cachet among the public, who then received a status boost for taking his work seriously,” writes Marx.
  • The internet, Marx writes in his book’s closing section, changes this dynamic. With so much content out there, the chance that others will recognize the meaning of any obscure cultural signal declines
  • in the age of the internet, taste tells you less about a person. You don’t need to make your way into any social world to develop a familiarity with Cage — or, for that matter, with underground hip-hop, weird performance art, or rare sneakers.
  • people are, obviously, no less obsessed with their own status today than they were during times of fecund cultural production.
  • the markers of high social rank have become more philistine. When the value of cultural capital is debased, writes Marx, it makes “popularity and economic capital even more central in marking status.”
  • there’s “less incentive for individuals to both create and celebrate culture with high symbolic complexity.”
  • It makes more sense for a parvenu to fake a ride on a private jet than to fake an interest in contemporary art. We live in a time of rapid and disorientating shifts in gender, religion and technology. Aesthetically, thanks to the internet, it’s all quite dull.

The "missing law" of nature was here all along | Salon.com - 0 views

  • recently published scientific article proposes a sweeping new law of nature, approaching the matter with dry, clinical efficiency that still reads like poetry.
  • “Evolving systems are asymmetrical with respect to time; they display temporal increases in diversity, distribution, and/or patterned behavior,” they continue, mounting their case from the shoulders of Charles Darwin, extending it toward all things living and not. 
  • To join the known physics laws of thermodynamics, electromagnetism and Newton’s laws of motion and gravity, the nine scientists and philosophers behind the paper propose their “law of increasing functional information.”
  • ...27 more annotations...
  • In short, a complex and evolving system — whether that’s a flock of gold finches or a nebula or the English language — will produce ever more diverse and intricately detailed states and configurations of itself.
  • Some of these more diverse and intricate configurations, the scientists write, are shed and forgotten over time. The configurations that persist are ones that find some utility or novel function in a process akin to natural selection, but a selection process driven by the passing-on of information rather than just the sowing of biological genes
  • Have they finally glimpsed, I wonder, the connectedness and symbiotic co-evolution of their own scientific ideas with those of the world’s writers
  • Have they learned to describe in their own quantifying language that cradle from which both our disciplines have emerged and the firmament on which they both stand — the hearing and telling of stories in order to exist?
  • Have they quantified the quality of all existent matter, living and not: that all things inherit a story in data to tell, and that our stories are told by the very forms we take to tell them? 
  • “Is there a universal basis for selection? Is there a more quantitative formalism underlying this conjectured conceptual equivalence—a formalism rooted in the transfer of information?,” they ask of the world’s disparate phenomena. “The answer to both questions is yes.”
  • In her Pulitzer-winning “Pilgrim at Tinker Creek,” nature writer Annie Dillard explains plainly that evolution is the vehicle of such intricacy in the natural world, as much as it is in our own thoughts and actions. 
  • The principle of complexity evolving at its own pace when left to its own devices, independent of time but certainly in a dance with it, is nothing new. Not in science, nor in its closest humanities kin, science and nature writing. Give things time and nourishing environs, protect them from your own intrusions and — living organisms or not — they will produce abundant enlacement of forms.
  • This is how poetry was born from the same larynxes and phalanges that tendered nuclear equations: We featherless bipeds gave language our time and delighted attendance until its forms were so multivariate that they overflowed with inevitable utility.
  • Yes. They’ve glimpsed it, whether they know it or not. Sing to me, O Muse, of functional information and its complex diversity.
  • “The stability of simple forms is the sturdy base from which more complex, stable forms might arise, forming in turn more complex forms,” she explains, drawing on the undercap frills of mushrooms and filament-fine filtering tubes inside human kidneys to illustrate her point. 
  • “Utility to the creature is evolution’s only aesthetic consideration. Form follows function in the created world, so far as I know, and the creature that functions, however bizarre, survives to perpetuate its form,” writes Dillard.
  • Or, as the Mishna would have it, “the creations were all made in generic form, and they gradually expanded.” 
  • She notes that, of all forms of life we’ve ever known to exist, only about 10% are still alive. What extravagant multiplicity. 
  • “Intricacy is that which is given from the beginning, the birthright, and in the intricacy is the hardiness of complexity that ensures against the failures of all life,” Dillard writes. “The wonder is — given the errant nature of freedom and the burgeoning texture of time — the wonder is that all the forms are not monsters, that there is beauty at all, grace gratuitous.”
  • “This paper, and the reason why I'm so proud of it, is because it really represents a connection between science and the philosophy of science that perhaps offers a new lens into why we see everything that we see in the universe,” lead scientist Michael Wong told Motherboard in a recent interview. 
  • Wong is an astrobiologist and planetary scientist at the Carnegie Institute for Science. In his team’s paper, that bridge toward scientific philosophy is not only preceded by a long history of literary creativity but directly theorizes about the creative act itself.  
  • “The creation of art and music may seem to have very little to do with the maintenance of society, but their origins may stem from the need to transmit information and create bonds among communities, and to this day, they enrich life in innumerable ways,” Wong’s team writes.  
  • “Perhaps, like eddies swirling off of a primary flow field, selection pressures for ancillary functions can become so distant from the core functions of their host systems that they can effectively be treated as independently evolving systems,” the authors add, pointing toward the elaborate mating dance culture observed in birds of paradise.
  • “Perhaps it will be humanity’s ability to learn, invent, and adopt new collective modes of being that will lead to its long-term persistence as a planetary phenomenon. In light of these considerations, we suspect that the general principles of selection and function discussed here may also apply to the evolution of symbolic and social systems.”
  • The Mekhilta teaches that all Ten Commandments were pronounced in a single utterance. Similarly, the Maharsha says the Torah’s 613 mitzvoth are only perceived as a plurality because we’re time-bound humans, even though they together form a singular truth which is indivisible from He who expressed it. 
  • “Of the multiplicity of forms, I know nothing. Except that, apparently, anything goes. This holds for forms of behavior as well as design — the mantis munching her mate, the frog wintering in mud.” 
  • Like swirling eddies off of a primary flow field.
  • “O Lord, how manifold are thy works!,” cried out David in his psalm. “In wisdom hast thou made them all: the earth is full of thy riches. So is this great and wide sea, wherein are things creeping innumerable, both small and great beasts.” 
  • Because, whether wittingly or not, science is singing the tune of the humanities. And whether expressed in algebraic logic or ancient Greek hymn, its chorus is the same throughout the universe: Be fruitful and multiply. 
  • In all things, then — from poetic inventions, to rare biodiverse ecosystems, to the charted history of our interstellar equations — it is best if we conserve our world’s intellectual and physical diversity, for both the study and testimony of its immeasurable multiplicity.
  • Both intricate configurations of art and matter arise and fade according to their shared characteristic, long-known by students of the humanities: each have been graced with enough time to attend to the necessary affairs of their most enduring pleasures.

An Existential Problem in the Search for Alien Life - The Atlantic - 0 views

  • The fact is, we still don’t know what life is.
  • since the days of Aristotle, scientists and philosophers have struggled to draw a precise line between what is living and what is not, often returning to criteria such as self-organization, metabolism, and reproduction but never finding a definition that includes, and excludes, all the right things.
  • If you say life consumes fuel to sustain itself with energy, you risk including fire; if you demand the ability to reproduce, you exclude mules. NASA hasn’t been able to do better than a working definition: “Life is a self-sustaining chemical system capable of Darwinian evolution.”
  • ...20 more annotations...
  • it lacks practical application. If humans found something on another planet that seemed to be alive, how much time would we have to sit around and wait for it to evolve?
  • The only life we know is life on Earth. Some scientists call this the n=1 problem, where n is the number of examples from which we can generalize.
  • Cronin studies the origin of life, also a major interest of Walker’s, and it turned out that, when expressed in math, their ideas were essentially the same. They had both zeroed in on complexity as a hallmark of life. Cronin is devising a way to systematize and measure complexity, which he calls Assembly Theory.
  • What we really want is more than a definition of life. We want to know what life, fundamentally, is. For that kind of understanding, scientists turn to theories. A theory is a scientific fundamental. It not only answers questions, but frames them, opening new lines of inquiry. It explains our observations and yields predictions for future experiments to test.
  • Consider the difference between defining gravity as “the force that makes an apple fall to the ground” and explaining it, as Newton did, as the universal attraction between all particles in the universe, proportional to the product of their masses and so on. A definition tells us what we already know; a theory changes how we understand things.
  • the potential rewards of unlocking a theory of life have captivated a clutch of researchers from a diverse set of disciplines. “There are certain things in life that seem very hard to explain,” Sara Imari Walker, a physicist at Arizona State University who has been at the vanguard of this work, told me. “If you scratch under the surface, I think there is some structure that suggests formalization and mathematical laws.”
  • Walker doesn’t think about life as a biologist—or an astrobiologist—does. When she talks about signs of life, she doesn’t talk about carbon, or water, or RNA, or phosphine. She reaches for different examples: a cup, a cellphone, a chair. These objects are not alive, of course, but they’re clearly products of life. In Walker’s view, this is because of their complexity. Life brings complexity into the universe, she says, in its own being and in its products, because it has memory: in DNA, in repeating molecular reactions, in the instructions for making a chair.
  • He measures the complexity of an object—say, a molecule—by calculating the number of steps necessary to put the object’s smallest building blocks together in that certain way. His lab has found, for example, when testing a wide range of molecules, that those with an “assembly number” above 15 were exclusively the products of life. Life makes some simpler molecules, too, but only life seems to make molecules that are so complex.
  • I reach for the theory of gravity as a familiar parallel. Someone might ask, “Okay, so in terms of gravity, where are we in terms of our understanding of life? Like, Newton?” Further back, further back, I say. Walker compares us to pre-Copernican astronomers, reliant on epicycles, little orbits within orbits, to make sense of the motion we observe in the sky. Cleland has put it in terms of chemistry, in which case we’re alchemists, not even true chemists yet
  • Walker’s whole notion is that it’s not only theoretically possible but genuinely achievable to identify something smaller—much smaller—that still nonetheless simply must be the result of life. The model would, in a sense, function like biosignatures as an indication of life that could be searched for. But it would drastically improve and expand the targets.
  • Walker would use the theory to predict what life on a given planet might look like. It would require knowing a lot about the planet—information we might have about Venus, but not yet about a distant exoplanet—but, crucially, would not depend at all on how life on Earth works, what life on Earth might do with those materials.
  • Without the ability to divorce the search for alien life from the example of life we know, Walker thinks, a search is almost pointless. “Any small fluctuations in simple chemistry can actually drive you down really radically different evolutionary pathways,” she told me. “I can’t imagine [life] inventing the same biochemistry on two worlds.”
  • Walker’s approach is grounded in the work of, among others, the philosopher of science Carol Cleland, who wrote The Quest for a Universal Theory of Life.
  • she warns that any theory of life, just like a definition, cannot be constrained by the one example of life we currently know. “It’s a mistake to start theorizing on the basis of a single example, even if you’re trying hard not to be Earth-centric. Because you’re going to be Earth-centric,” Cleland told me. In other words, until we find other examples of life, we won’t have enough data from which to devise a theory. Abstracting away from Earthliness isn’t a way to be agnostic, Cleland argues. It’s a way to be too abstract.
  • Cleland calls for a more flexible search guided by what she calls “tentative criteria.” Such a search would have a sense of what we’re looking for, but also be open to anomalies that challenge our preconceptions, detections that aren’t life as we expected but aren’t familiar not-life either—neither a flower nor a rock
  • it speaks to the hope that exploration and discovery might truly expand our understanding of the cosmos and our own world.
  • The astrobiologist Kimberley Warren-Rhodes studies life on Earth that lives at the borders of known habitability, such as in Chile’s Atacama Desert. The point of her experiments is to better understand how life might persist—and how it might be found—on Mars. “Biology follows some rules,” she told me. The more of those rules you observe, the better sense you have of where to look on other worlds.
  • In this light, the most immediate concern in our search for extraterrestrial life might be less that we only know about life on Earth, and more that we don’t even know that much about life on Earth in the first place. “I would say we understand about 5 percent,” Warren-Rhodes estimates of our cumulative knowledge. N=1 is a problem, and we might be at more like n=.05.
  • who knows how strange life on another world might be? What if life as we know it is the wrong life to be looking for?
  • We understand so little, and we think we’re ready to find other life?

Overstimulation Nation - Slack Tide by Matt Labash - 0 views

  • The local radio jock said to me, “You must think all of this is pretty silly”. He motioned towards the crowd and then to a rollercoaster directly beside us that came screeching at our heads every 95 seconds. But I said, “No. In a century people are going to look back on right now as a sort of magic era, a charmed time of peace and prosperity and freedom from fear, as something that can never happen again, no matter how much they wish it would.”
  • telling the truth always liberates us, even if it scares the hell out of us simultaneously
  • Bad things have always happened in this world. That’s nothing new. And bad things will continue to have their uninterrupted run, right until the end of time.  But the “freedom from fear” Coupland speaks of is largely a function of not wallowing in it all the live-long day, which  our trusty bad-news delivery systems are pretty good about making us do. They give us the illusion of constant movement, even if our only destination is backwards, prompting us to forever double down on fear, and agitation, and mutual suspicion, while steeping us in our own soul sickness.

  • It’s a trap, which maybe seeking out a little more deliberate boredom – also known as stillness - could help us avoid
  • Thomas Merton, whose praises I have sung in these pages before, framed it:
  • being bored might be a good start for healing what ails us.
  • But the purity of our conscience has a natural proportion with the depth of our being and the quality of our acts: and when our activity is habitually disordered, our malformed conscience can think of nothing better to tell us than to multiply the *quantity* of our acts, without perfecting their quality. And so we go from bad to worse, exhaust ourselves, empty our whole life of all content, and fall into despair
  • There are times, then, when in order to keep ourselves in existence at all we simply have to sit back for a while and do nothing. And for a man who has let himself be drawn completely out of himself by his activity, nothing is more difficult than to sit still and rest, doing nothing at all. The very act of resting is the hardest and most courageous act he can perform: and often it is quite beyond his power.
  • Our being is not to be enriched merely by activity or experience as such. Everything depends on the *quality* of our acts and our experiences. A multitude of badly performed actions and of experiences only half lived exhausts and depletes our being. By doing things badly we make ourselves less real. This growing unreality cannot help but make us unhappy and fill us with a sense of guilt
  • even with all the excitement, I couldn’t sustain any. I was bored by the excitement. Or rather, I craved boredom, finding all the excitement dull in a not-this-shitshow-again sort of way. For the last decade or so, we’ve been too over-excited, over-provoked, and overstimulated.
