Einstein's Theory of Relativity, Explained in a Pioneering 1923 Silent Film - Brain Pic... - 0 views

  • “This is a participatory universe,” physicist John Archibald Wheeler, who popularized the term black hole, wrote in his influential theory known as It from Bit, asserting that “physics gives rise to observer-participancy; observer-participancy gives rise to information; and information gives rise to physics” — an assertion he could not have made without Einstein’s theory of relativity and its groundbreaking insight into how the laws of physics appear to different observers with different frames of reference.

The Economic Case for Regulating Social Media - The New York Times - 0 views

  • Social media platforms like Facebook, YouTube and Twitter generate revenue by using detailed behavioral information to direct ads to individual users.
  • this bland description of their business model fails to convey even a hint of its profound threat to the nation’s political and social stability.
  • legislators in Congress to propose the breakup of some tech firms, along with other traditional antitrust measures. But the main hazard posed by these platforms is not aggressive pricing, abusive service or other ills often associated with monopoly.

  • Instead, it is their contribution to the spread of misinformation, hate speech and conspiracy theories.
  • digital platforms, since the marginal cost of serving additional consumers is essentially zero. Because the initial costs of producing a platform’s content are substantial, and because any company’s first goal is to remain solvent, it cannot just give stuff away. Even so, when price exceeds marginal cost, competition relentlessly pressures rival publishers to cut prices — eventually all the way to zero. This, in a nutshell, is the publisher’s dilemma in the digital age.
  • These firms make money not by charging for access to content but by displaying it with finely targeted ads based on the specific types of things people have already chosen to view. If the conscious intent were to undermine social and political stability, this business model could hardly be a more effective weapon.
  • The algorithms that choose individual-specific content are crafted to maximize the time people spend on a platform
  • As the developers concede, Facebook’s algorithms are addictive by design and exploit negative emotional triggers. Platform addiction drives earnings, and hate speech, lies and conspiracy theories reliably boost addiction.
  • the subscription model isn’t fully efficient: Any positive fee would inevitably exclude at least some who would value access but not enough to pay the fee
  • a conservative think tank, says, for example, that government has no business second-guessing people’s judgments about what to post or read on social media.
  • That position would be easier to defend in a world where individual choices had no adverse impact on others. But negative spillover effects are in fact quite common
  • individual and collective incentives about what to post or read on social media often diverge sharply.
  • There is simply no presumption that what spreads on these platforms best serves even the individual’s own narrow interests, much less those of society as a whole.
  • a simpler step may hold greater promise: Platforms could be required to abandon that model in favor of one relying on subscriptions, whereby members gain access to content in return for a modest recurring fee.
  • Major newspapers have done well under this model, which is also making inroads in book publishing. The subscription model greatly weakens the incentive to offer algorithmically driven addictive content provided by individuals, editorial boards or other sources.
  • Careful studies have shown that Facebook’s algorithms have increased political polarization significantly
  • More worrisome, those excluded would come disproportionately from low-income groups. Such objections might be addressed specifically — perhaps with a modest tax credit to offset subscription fees — or in a more general way, by making the social safety net more generous.
  • Adam Smith, the 18th-century Scottish philosopher widely considered the father of economics, is celebrated for his “invisible hand” theory, which describes conditions under which market incentives promote socially benign outcomes. Many of his most ardent admirers may view steps to constrain the behavior of social media platforms as regulatory overreach.
  • But Smith’s remarkable insight was actually more nuanced: Market forces often promote society’s welfare, but not always. Indeed, as he saw clearly, individual interests are often squarely at odds with collective aspirations, and in many such instances it is in society’s interest to intervene. The current information crisis is a case in point.

'Oppenheimer,' 'The Maniac' and Our Terrifying Prometheus Moment - The New York Times - 0 views

  • Prometheus was the Titan who stole fire from the gods of Olympus and gave it to human beings, setting us on a path of glory and disaster and incurring the jealous wrath of Zeus. In the modern world, especially since the beginning of the Industrial Revolution, he has served as a symbol of progress and peril, an avatar of both the liberating power of knowledge and the dangers of technological overreach.
  • More than 200 years after the Shelleys, Prometheus is having another moment, one closer in spirit to Mary’s terrifying ambivalence than to Percy’s fulsome gratitude. As technological optimism curdles in the face of cyber-capitalist villainy, climate disaster and what even some of its proponents warn is the existential threat of A.I., that ancient fire looks less like an ember of divine ingenuity than the start of a conflagration. Prometheus is what we call our capacity for self-destruction.
  • Annie Dorsen’s theater piece “Prometheus Firebringer,” which was performed at Theater for a New Audience in September, updates the Greek myth for the age of artificial intelligence, using A.I. to weave a cautionary tale that my colleague Laura Collins-Hughes called “forcefully beneficial as an examination of our obeisance to technology.”

  • Something similar might be said about “The Maniac,” Benjamín Labatut’s new novel, whose designated Prometheus is the Hungarian-born polymath John von Neumann, a pioneer of A.I. as well as an originator of game theory.
  • both narratives are grounded in fact, using the lives and ideas of real people as fodder for allegory and attempting to write a new mythology of the modern world.
  • Oppenheimer wasn’t a principal author of that theory. Those scientists, among them Niels Bohr, Erwin Schrödinger and Werner Heisenberg, were characters in Labatut’s previous novel, “When We Cease to Understand the World.” That book provides harrowing illumination of a zone where scientific insight becomes indistinguishable from madness or, perhaps, divine inspiration. The basic truths of the new science seem to explode all common sense: A particle is also a wave; one thing can be in many places at once; “scientific method and its object could no longer be prised apart.”
  • More than most intellectual bastions, the institute is a house of theory. The Promethean mad scientists of the 19th century were creatures of the laboratory, tinkering away at their infernal machines and homemade monsters. Their 20th-century counterparts were more likely to be found at the chalkboard, scratching out our future in charts, equations and lines of code.
  • The consequences are real enough, of course. The bombs dropped on Hiroshima and Nagasaki killed at least 100,000 people. Their successor weapons, which Oppenheimer opposed, threatened to kill everybody els
  • on Neumann and Oppenheimer were close contemporaries, born a year apart to prosperous, assimilated Jewish families in Budapest and New York. Von Neumann, conversant in theoretical physics, mathematics and analytic philosophy, worked for Oppenheimer at Los Alamos during the Manhattan Project. He spent most of his career at the Institute for Advanced Study, where Oppenheimer served as director after the war.
  • the intellectual drama of “Oppenheimer” — as distinct from the dramas of his personal life and his political fate — is about how abstraction becomes reality. The atomic bomb may be, for the soldiers and politicians, a powerful strategic tool in war and diplomacy. For the scientists, it’s something else: a proof of concept, a concrete manifestation of quantum theory.
  • . Oppenheimer’s designation as Prometheus is precise. He snatched a spark of quantum insight from those divinities and handed it to Harry S. Truman and the U.S. Army Air Forces.
  • Labatut’s account of von Neumann is, if anything, more unsettling than “Oppenheimer.” We had decades to get used to the specter of nuclear annihilation, and since the end of the Cold War it has been overshadowed by other terrors. A.I., on the other hand, seems newly sprung from science fiction, and especially terrifying because we can’t quite grasp what it will become.
  • Von Neumann, who died in 1957, did not teach machines to play Go. But when asked “what it would take for a computer, or some other mechanical entity, to begin to think and behave like a human being,” he replied that “it would have to play, like a child.”
  • MANIAC. The name was an acronym for “Mathematical Analyzer, Numerical Integrator and Computer,” which doesn’t sound like much of a threat. But von Neumann saw no limit to its potential. “If you tell me precisely what it is a machine cannot do,” he declared, “then I can always make a machine which will do just that.” MANIAC didn’t just represent a powerful new kind of machine, but “a new type of life.”
  • If Oppenheimer took hold of the sacred fire of atomic power, von Neumann’s theft was bolder and perhaps more insidious: He stole a piece of the human essence. He’s not only a modern Prometheus; he’s a second Frankenstein, creator of an all but human, potentially more than human monster.
  • “Technological power as such is always an ambivalent achievement,” Labatut’s von Neumann writes toward the end of his life, “and science is neutral all through, providing only means of control applicable to any purpose, and indifferent to all. It is not the particularly perverse destructiveness of one specific invention that creates danger. The danger is intrinsic. For progress there is no cure.”

Psychological nativism - Wikipedia - 0 views

  • In the field of psychology, nativism is the view that certain skills or abilities are "native" or hard-wired into the brain at birth. This is in contrast to the "blank slate" or tabula rasa view, which states that the brain has inborn capabilities for learning from the environment but does not contain content such as innate beliefs.
  • Some nativists believe that specific beliefs or preferences are "hard-wired". For example, one might argue that some moral intuitions are innate or that color preferences are innate. A less established argument is that nature supplies the human mind with specialized learning devices. This latter view differs from empiricism only to the extent that the algorithms that translate experience into information may be more complex and specialized in nativist theories than in empiricist theories. However, empiricists largely remain open to the nature of learning algorithms and are by no means restricted to the historical associationist mechanisms of behaviorism.
  • Nativism has a history in philosophy, particularly as a reaction to the straightforward empiricist views of John Locke and David Hume. Hume had given persuasive logical arguments that people cannot infer causality from perceptual input. The most one could hope to infer is that two events happen in succession or simultaneously. One response to this argument involves positing that concepts not supplied by experience, such as causality, must exist prior to any experience and hence must be innate.
  • ...14 more annotations...
  • The philosopher Immanuel Kant (1724–1804) argued in his Critique of Pure Reason that the human mind knows objects in innate, a priori ways. Kant claimed that humans, from birth, must experience all objects as being successive (time) and juxtaposed (space). His list of inborn categories describes predicates that the mind can attribute to any object in general. Arthur Schopenhauer (1788–1860) agreed with Kant, but reduced the number of innate categories to one—causality—which presupposes the others.
  • Modern nativism is most associated with the work of Jerry Fodor (1935–2017), Noam Chomsky (b. 1928), and Steven Pinker (b. 1954), who argue that humans from birth have certain cognitive modules (specialised genetically inherited psychological abilities) that allow them to learn and acquire certain skills, such as language.
  • For example, children demonstrate a facility for acquiring spoken language but require intensive training to learn to read and write. This poverty of the stimulus observation became a principal component of Chomsky's argument for a "language organ"—a genetically inherited neurological module that confers a somewhat universal understanding of syntax that all neurologically healthy humans are born with, which is fine-tuned by an individual's experience with their native language
  • In The Blank Slate (2002), Pinker similarly cites the linguistic capabilities of children, relative to the amount of direct instruction they receive, as evidence that humans have an inborn facility for speech acquisition (but not for literacy acquisition).
  • A number of other theorists[1][2][3] have disagreed with these claims. Instead, they have outlined alternative theories of how modularization might emerge over the course of development, as a result of a system gradually refining and fine-tuning its responses to environmental stimuli.[4]
  • Many empiricists are now also trying to apply modern learning models and techniques to the question of language acquisition, with marked success.[20] Similarity-based generalization marks another avenue of recent research, which suggests that children may be able to rapidly learn how to use new words by generalizing about the usage of similar words that they already know (see also the distributional hypothesis).[14][21][22][23]
  • The term universal grammar (or UG) is used for the purported innate biological properties of the human brain, whatever exactly they turn out to be, that are responsible for children's successful acquisition of a native language during the first few years of life. The person most strongly associated with the hypothesising of UG is Noam Chomsky, although the idea of Universal Grammar has clear historical antecedents at least as far back as the 1300s, in the form of the Speculative Grammar of Thomas of Erfurt.
  • This evidence is all the more impressive when one considers that most children do not receive reliable corrections for grammatical errors.[9] Indeed, even children who for medical reasons cannot produce speech, and therefore have no possibility of producing an error in the first place, have been found to master both the lexicon and the grammar of their community's language perfectly.[10] The fact that children succeed at language acquisition even when their linguistic input is severely impoverished, as it is when no corrective feedback is available, is related to the argument from the poverty of the stimulus, and is another claim for a central role of UG in child language acquisition.
  • Researchers at Blue Brain discovered a network of about fifty neurons which they believed were building blocks of more complex knowledge but contained basic innate knowledge that could be combined in different more complex ways to give way to acquired knowledge, like memory.[11
  • experience, the tests would bring about very different characteristics for each rat. However, the rats all displayed similar characteristics which suggest that their neuronal circuits must have been established previously to their experiences. The Blue Brain Project research suggests that some of the "building blocks" of knowledge are genetic and present at birth.[11]
  • modern nativist theory makes little in the way of specific falsifiable and testable predictions, and has been compared by some empiricists to a pseudoscience or nefarious brand of "psychological creationism". As influential psychologist Henry L. Roediger III remarked that "Chomsky was and is a rationalist; he had no uses for experimental analyses or data of any sort that pertained to language, and even experimental psycholinguistics was and is of little interest to him".[13]
  • , Chomsky's poverty of the stimulus argument is controversial within linguistics.[14][15][16][17][18][19]
  • Neither the five-year-old nor the adults in the community can easily articulate the principles of the grammar they are following. Experimental evidence shows that infants come equipped with presuppositions that allow them to acquire the rules of their language.[6]
  • Paul Griffiths, in "What is Innateness?", argues that innateness is too confusing a concept to be fruitfully employed as it confuses "empirically dissociated" concepts. In a previous paper, Griffiths argued that innateness specifically confuses these three distinct biological concepts: developmental fixity, species nature, and intended outcome. Developmental fixity refers to how insensitive a trait is to environmental input, species nature reflects what it is to be an organism of a certain kind, and the intended outcome is how an organism is meant to develop.[24]

Tracking Viral Misinformation - The New York Times - 0 views

  • More than a year after Donald J. Trump left office, the QAnon conspiracy theory that thrived during his administration continues to attract more Americans, including many Republicans and far-right news consumers, according to results from a survey released on Thursday from the Public Religion Research Institute.
  • The nonprofit and nonpartisan group found that 16 percent of Americans, or roughly 41 million people, believed last year in the three key tenets of the conspiracy theory
  • Those are that Satanist pedophiles who run a global child sex-trafficking operation control the government and other major institutions
  • ...14 more annotations...
  • that a coming storm will sweep elites from power
  • and that violence might be necessary to save the country.
  • In October 2021, 17 percent of Americans believed in the conspiracy theory, up from 14 percent in March
  • the percentage of people who rejected QAnon falsehoods shrank to 34 percent in October from 40 percent in March
  • After Mr. Trump lost the 2020 presidential election, QAnon was expected to be hobbled without him. But it has persisted despite that and despite efforts by tech platforms to staunch its spread. Forensic linguists have also tried to unmask and defang the anonymous author who signed online messages as Q.
  • Robert P. Jones, the founder and chief executive of the research group and a social science researcher with decades of experience, said he never expected to be dealing with serious survey questions about whether powerful American institutions were controlled by devil-worshiping, sex-trafficking pedophiles. To have so many Americans agree with such a question, he said, was “stunning.”
  • Believers are “racially, religiously and politically diverse,”
  • Among Republicans, 25 percent found QAnon to be valid, compared with 14 percent of independents and 9 percent of Democrats.
  • Media preferences were a major predictor of QAnon susceptibility, with people who trust far-right news sources such as One America News Network and Newsmax nearly five times more likely to be believers than those who trust mainstream news
  • Fox News viewers were twice as likely to back QAnon ideas
  • Most QAnon believers associated Christianity with being American and said that the United States risked losing its culture and identity and must be protected from foreign influence
  • seven in 10 believers agreed with the lie that the 2020 election was stolen from Mr. Trump.
  • More than half of QAnon supporters are white, while 20 percent are Hispanic and 13 percent are Black.
  • They were most likely to have household incomes of less than $50,000 a year, hold at most a high school degree, hail from the South and reside in a suburb.

Drones, Ethics and the Armchair Soldier - NYTimes.com - 0 views

  • the difference between humans and robots is precisely the ability to think and reflect, in Immanuel Kant’s words, to set and pursue ends for themselves. And these ends cannot be set beforehand in some hard and fast way
  • Working one’s way through the complexities of “just war” and moral theory makes it perfectly clear that ethics is not about arriving easily at a single right answer, but rather coming to understand the profound difficulty of doing so. Experiencing this difficulty is what philosophers call existential responsibility.
  • One of the jobs of philosophy, at least as I understand it, is neither to help people to avoid these difficulties nor to exaggerate them, but rather to face them in resolute and creative ways.

  • ground troops, unfortunately, had more pressing concerns than existential responsibility. They did not have leisure, unlike their commanders, who also often had the philosophical training to think through the complexities of their jobs.
  • This training was not simply a degree requirement at Officer Candidate School or one of the United States military academies, but a sustained, ongoing, and rigorous engagement with a philosophical tradition. Alexander lived with Aristotle.
  • , Jeff McMahan argued that traditional “just war theory” should be reworked in several important ways. He suggested that the tenets of a revised theory apply not only to governments, traditionally represented by commanders and heads of state, but also to individual soldiers. This is a significant revision since it broadens the scope of responsibility for warfare
  • McMahan believes that individuals are to bear at least some responsibility in upholding “just cause” requirements. McMahan expects more of soldiers and, in this age of drones and leisure, he is right to do so.
  • while drones are to be applauded for keeping these soldiers out of harm’s way physically, we would do well to remember that they do not keep them out of harm’s way morally or psychologically. The high rates of “burnout” should drive this home. Supporting our troops requires ensuring that they are provided not just with training and physical armor, but with the intellectual tools to navigate these new difficulties.
  • Just as was the case in the invasion of Iraq 10 years ago, the most important questions we should be asking should not be directed to armchair soldiers but to those of us in armchairs at home: What wars are being fought in our name? On what grounds are they being fought?

10 Reasons the Moon Landings Could Be a Hoax - Listverse - 1 views

  • The theory that the moon landings were hoaxed by the US government to assert their victory in the space race over Russia, is something which has grown in popularity over time.
  •  
    I don't know if the first Moon Landing is real or not, but this article reminds me of the conspiracy theory we learned in TOK. After reading through those reasons and evidences, the credibility of the first moon landing decreases. However, there are still possibilities that the moon landing is real. Confirmation bias may also play a role because I only noticed the "strange" part of the photo after I read the writing below. And also, I think that Richard Nixon must be one of the reason why people don't believe in the first moon landing. --Sissi (1/8/2017)

Charlie Sykes on Where the Right Went Wrong - The New York Times - 0 views

  • t I have to admit that the campaign has made my decision easier. The conservative media is broken and the conservative movement deeply compromised.
  • Before this year, I thought I had a relatively solid grasp on what conservatism stood for and where it was going
  • I was under the impression that conservatives actually believed things about free trade, balanced budgets, character and respect for constitutional rights. Then along came this campaign.
  • ...15 more annotations...
  • When I wrote in August 2015 that Mr. Trump was a cartoon version of every left-wing media stereotype of the reactionary, nativist, misogynist right, I thought that I was well within the mainstream of conservative thought — only to find conservative Trump critics denounced for apostasy by a right that decided that it was comfortable with embracing Trumpism.
  • relatively few of my listeners bought into the crude nativism Mr. Trump was selling at his rallies.
  • What they did buy into was the argument that this was a “binary choice.” No matter how bad Mr. Trump was, my listeners argued, he could not possibly be as bad as Mrs. Clinton. You simply cannot overstate this as a factor in the final outcome
  • Even among Republicans who had no illusions about Mr. Trump’s character or judgment, the demands of that tribal loyalty took precedence. To resist was an act of betrayal.
  • In this binary tribal world, where everything is at stake, everything is in play, there is no room for quibbles about character, or truth, or principles.
  • If everything — the Supreme Court, the fate of Western civilization, the survival of the planet — depends on tribal victory, then neither individuals nor ideas can be determinative.
  • As our politics have become more polarized, the essential loyalties shift from ideas, to parties, to tribes, to individuals. Nothing else ultimately matters.
  • For many listeners, nothing was worse than Hillary Clinton. Two decades of vilification had taken their toll: Listeners whom I knew to be decent, thoughtful individuals began forwarding stories with conspiracy theories about President Obama and Mrs. Clinton — that he was a secret Muslim, that she ran a child sex ring out of a pizza parlor. When I tried to point out that such stories were demonstrably false, they generally refused to accept evidence that came from outside their bubble. The echo chamber had morphed into a full-blown alternate reality silo of conspiracy theories, fake news and propaganda.
  • In this political universe, voters accept that they must tolerate bizarre behavior, dishonesty, crudity and cruelty, because the other side is always worse; the stakes are such that no qualms can get in the way of the greater cause.
  • When it became clear that I was going to remain #NeverTrump, conservatives I had known and worked with for more than two decades organized boycotts of my show. One prominent G.O.P. activist sent out an email blast calling me a “Judas goat,” and calling for postelection retribution.
  • And then, there was social media. Unless you have experienced it, it’s difficult to describe the virulence of the Twitter storms that were unleashed on Trump skeptics. In my timelines, I found myself called a “cuckservative,” a favorite gibe of white nationalists; and someone Photoshopped my face into a gas chamber. Under the withering fire of the trolls, one conservative commentator and Republican political leader after another fell in line.
  • we had succeeded in persuading our audiences to ignore and discount any information from the mainstream media. Over time, we’d succeeded in delegitimizing the media altogether — all the normal guideposts were down, the referees discredited.
  • That left a void that we conservatives failed to fill. For years, we ignored the birthers, the racists, the truthers and other conspiracy theorists who indulged fantasies of Mr. Obama’s secret Muslim plot to subvert Christendom, or who peddled baseless tales of Mrs. Clinton’s murder victims. Rather than confront the purveyors of such disinformation, we changed the channel because, after all, they were our allies, whose quirks could be allowed or at least ignored
  • We destroyed our own immunity to fake news, while empowering the worst and most reckless voices on the right.
  • This was not mere naïveté. It was also a moral failure, one that now lies at the heart of the conservative movement even in its moment of apparent electoral triumph. Now that the election is over, don’t expect any profiles in courage from the Republican Party pushing back against those trends; the gravitational pull of our binary politics is too strong.

What Happened Before the Big Bang? The New Philosophy of Cosmology - Ross Andersen - Te... - 1 views

  • This question of accounting for what we call the "big bang state" -- the search for a physical explanation of it -- is probably the most important question within the philosophy of cosmology, and there are a couple different lines of thought about it.
  • One that's becoming more and more prevalent in the physics community is the idea that the big bang state itself arose out of some previous condition, and that therefore there might be an explanation of it in terms of the previously existing dynamics by which it came about
  • The problem is that quantum mechanics was developed as a mathematical tool. Physicists understood how to use it as a tool for making predictions, but without an agreement or understanding about what it was telling us about the physical world. And that's very clear when you look at any of the foundational discussions. This is what Einstein was upset about; this is what Schrodinger was upset about. Quantum mechanics was merely a calculational technique that was not well understood as a physical theory. Bohr and Heisenberg tried to argue that asking for a clear physical theory was something you shouldn't do anymore. That it was something outmoded. And they were wrong, Bohr and Heisenberg were wrong about that. But the effect of it was to shut down perfectly legitimate physics questions within the physics community for about half a century. And now we're coming out of that

  • One common strategy for thinking about this is to suggest that what we used to call the whole universe is just a small part of everything there is, and that we live in a kind of bubble universe, a small region of something much larger
  • Newton realized there had to be some force holding the moon in its orbit around the earth, to keep it from wandering off, and he knew also there was a force that was pulling the apple down to the earth. And so what suddenly struck him was that those could be one and the same thing, the same force
  • That was a physical discovery, a physical discovery of momentous importance, as important as anything you could ever imagine because it knit together the terrestrial realm and the celestial realm into one common physical picture. It was also a philosophical discovery in the sense that philosophy is interested in the fundamental natures of things.
  • There are other ideas, for instance that maybe there might be special sorts of laws, or special sorts of explanatory principles, that would apply uniquely to the initial state of the universe.
  • The basic philosophical question, going back to Plato, is "What is x?" What is virtue? What is justice? What is matter? What is time? You can ask that about dark energy - what is it? And it's a perfectly good question.
  • right now there are just way too many freely adjustable parameters in physics. Everybody agrees about that. There seem to be many things we call constants of nature that you could imagine setting at different values, and most physicists think there shouldn't be that many, that many of them are related to one another. Physicists think that at the end of the day there should be one complete equation to describe all physics, because any two physical systems interact and physics has to tell them what to do. And physicists generally like to have only a few constants, or parameters of nature. This is what Einstein meant when he famously said he wanted to understand what kind of choices God had --using his metaphor-- how free his choices were in creating the universe, which is just asking how many freely adjustable parameters there are. Physicists tend to prefer theories that reduce that number
  • You have others saying that time is just an illusion, that there isn't really a direction of time, and so forth. I myself think that all of the reasons that lead people to say things like that have very little merit, and that people have just been misled, largely by mistaking the mathematics they use to describe reality for reality itself. If you think that mathematical objects are not in time, and mathematical objects don't change -- which is perfectly true -- and then you're always using mathematical objects to describe the world, you could easily fall into the idea that the world itself doesn't change, because your representations of it don't.
  • physicists for almost a hundred years have been dissuaded from trying to think about fundamental questions. I think most physicists would quite rightly say "I don't have the tools to answer a question like 'what is time?' - I have the tools to solve a differential equation." The asking of fundamental physical questions is just not part of the training of a physicist anymore.
  • The question remains as to how often, after life evolves, you'll have intelligent life capable of making technology. What people haven't seemed to notice is that on earth, of all the billions of species that have evolved, only one has developed intelligence to the level of producing technology. Which means that kind of intelligence is really not very useful. It's not actually, in the general case, of much evolutionary value. We tend to think, because we love to think of ourselves, human beings, as the top of the evolutionary ladder, that the intelligence we have, that makes us human beings, is the thing that all of evolution is striving toward. But what we know is that that's not true. Obviously it doesn't matter that much if you're a beetle, that you be really smart. If it were, evolution would have produced much more intelligent beetles. We have no empirical data to suggest that there's a high probability that evolution on another planet would lead to technological intelligence.

Science Can't Prove Anything - Proslogion - 1 views

  • Science Can’t Prove Anything Aug.11,2011 Sir Karl Popper's foundational work, The Logic of Scientific Discovery, makes it clear that science cannot prove anything (click for credit)In one of my science textbooks, I make the statement that science cannot prove anything.1 I am always surprised at how controversial such a matter-of-fact statement is to some people. Almost every year, at least one student or parent will contact me simply aghast that I would write something like that in a science textbook. After all, science has proven all sorts of things, hasn’t it?
  • . I find myself frequently repeating to students and the public that science doesn’t “prove” theories. Scientific measurements can only disprove theories or be consistent with them. Any theory that is consistent with measurements could be disproved by a future measurement.
  • Unfortunately, as long as science magazines and teachers are sloppy enough to keep using phrases like, “science has proven,” it will be hard to teach children the truth
  •  
    This highlights one of major flaws of the public's response and interpretation of science - and the system that relies on doubt and welcomes human uncertainty - that we can never truly prove anything. (Evie - 12/7/16)

Moral Puzzles That Tots Struggle With | Mind & Matter - WSJ.com - 2 views

  • Back in the 1980s, Judith Smetana and colleagues discovered that very young kids could discriminate between genuinely moral principles and mere social conventions. First, the researchers asked about everyday rules—a rule that you can't be mean to other children, for instance, or that you have to hang up your clothes. The children said that, of course, breaking the rules was wrong. But then the researchers asked another question: What would you think if teachers and parents changed the rules to say that being mean and dropping clothes were OK? Children as young as 2 said that, in that case, it would be OK to drop your clothes, but not to be mean. No matter what the authorities decreed, hurting others, even just hurting their feelings, was always wrong. It's a strikingly robust result—true for children from Brazil to Korea.
  • in the new study, Dr. Rhodes asked similar moral questions about the Zazes and Flurps. The 4-year-olds said it would always be wrong for Zazes to hurt the feelings of others in their group. But if teachers decided that Zazes could hurt Flurps' feelings, then it would be OK to do so. Intrinsic moral obligations only extended to members of their own group.
  • The 4-year-olds demonstrate the deep roots of an ethical tension that has divided philosophers for centuries. We feel that our moral principles should be universal, but we simultaneously feel that there is something special about our obligations to our own group, whether it's a family, clan or country.
  • you don't have to be taught to prefer your own group—you can pick that up fine by yourself. But we do have to teach our children how to widen the moral circle, and to extend their natural compassion and care even to the Flurps.

How 'Concept Creep' Made Americans So Sensitive to Harm - The Atlantic - 0 views

  • How did American culture arrive at these moments? A new research paper by Nick Haslam, a professor of psychology at the University of Melbourne, Australia, offers as useful a framework for understanding what’s going on as any I’ve seen. In “Concept Creep: Psychology's Expanding Concepts of Harm and Pathology,”
  • concepts like abuse, bullying, trauma, mental disorder, addiction, and prejudice, “now encompass a much broader range of phenomena than before,”expanded meanings that reflect “an ever-increasing sensitivity to harm.”
  • “they also have potentially damaging ramifications for society and psychology that cannot be ignored.”
  • ...20 more annotations...
  • He calls these expansions of meaning “concept creep.”
  • critics may hold concept creep responsible for damaging cultural trends, he writes, “such as supposed cultures of fear, therapy, and victimhood, the shifts I present have some positive implications.”
  • Concept creep is inevitable and vital if society is to make good use of new information. But why has the direction of concept creep, across so many different concepts, trended toward greater sensitivity to harm as opposed to lesser sensitivity?
  • The concept of abuse expanded too far.
  • Classically, psychological investigations recognized two forms of child abuse, physical and sexual, Haslam writes. In more recent decades, however, the concept of abuse has witnessed “horizontal creep” as new forms of abuse were recognized or studied. For example, “emotional abuse” was added as a new subtype of abuse. Neglect, traditionally a separate category, came to be seen as a type of abuse, too.
  • Meanwhile, the concept of abuse underwent “vertical creep.” That is, the behavior seen as qualifying for a given kind of abuse became steadily less extreme. Some now regard any spanking as physical abuse. Within psychology, “the boundary of neglect is indistinct,” Haslam writes. “As a consequence, the concept of neglect can become over-inclusive, identifying behavior as negligent that is substantially milder or more subtle than other forms of abuse. This is not to deny that some forms of neglect are profoundly damaging, merely to argue that the concept’s boundaries are sufficiently vague and elastic to encompass forms that are not severe.”
  • How did a working-class mom get arrested, lose her fast food job, and temporarily lose custody of her 9-year-old for letting the child play alone at a nearby park?
  • One concerns the field of psychology and its incentives. “It could be argued that just as successful species increase their territory, invading and adapting to new habitats, successful concepts and disciplines also expand their range into new semantic niches,” he theorizes. “Concepts that successfully attract the attention of researchers and practitioners are more likely to be applied in new ways and new contexts than those that do not.”
  • Concept creep can be necessary or needless. It can align concepts more or less closely with underlying realities. It can change society for better or worse. Yet many who push for more sensitivy to harm seem unaware of how oversensitivty can do harm.
  • The other theory posits an ideological explanation. “Psychology has played a role in the liberal agenda of sensitivity to harm and responsiveness to the harmed,” he writes “and its increased focus on negative phenomena—harms such as abuse, addiction, bullying, mental disorder, prejudice, and trauma—has been symptomatic of the success of that social agenda.”
  • Jonathan Haidt, who believes it has gone too far, offers a fourth theory. “If an increasingly left-leaning academy is staffed by people who are increasingly hostile to conservatives, then we can expect that their concepts will shift, via motivated scholarship, in ways that will help them and their allies (e.g., university administrators) to prosecute and condemn conservatives,
  • While Haslam and Haidt appear to have meaningfully different beliefs about why concept creep arose within academic psychology and spread throughout society, they were in sufficient agreement about its dangers to co-author a Guardian op-ed on the subject.
  • It focuses on how greater sensitivity to harm has affected college campuses.
  • “Of course young people need to be protected from some kinds of harm, but overprotection is harmful, too, for it causes fragility and hinders the development of resilience,” they wrote. “As Nasim Taleb pointed out in his book Antifragile, muscles need resistance to develop, bones need stress and shock to strengthen and the growing immune system needs to be exposed to pathogens in order to function. Similarly, he noted, children are by nature anti-fragile – they get stronger when they learn to recover from setbacks, failures and challenges to their cherished ideas.”
  • police officers fearing harm from dogs kill them by the hundreds or perhaps thousands every year in what the DOJ calls an epidemic.
  • After the terrorist attacks of September 11, 2001, the Bush Administration and many Americans grew increasingly sensitive to harms, real and imagined, from terrorism
  • Dick Cheney declared, “If there's a 1% chance that Pakistani scientists are helping al-Qaeda build or develop a nuclear weapon, we have to treat it as a certainty in terms of our response. It's not about our analysis ... It's about our response.” The invasion of Iraq was predicated, in part, on the idea that 9/11 “changed everything,”
  • Before 9/11, the notion of torturing prisoners was verboten. After the Bush Administration’s torture was made public, popular debate focused on mythical “ticking time bomb” scenarios, in which a whole city would be obliterated but for torture. Now Donald Trump suggests that torture should be used more generally against terrorists. Torture is, as well, an instance in which people within the field of psychology pushed concept creep in the direction of less sensitivity to harm,
  • Haslam endorses two theories
  • there are many reasons to be concerned about excessive sensitivity to harm:

How 'Empowerment' Became Something for Women to Buy - The New York Times - 0 views

  • The mix of things presumed to transmit and increase female power is without limit yet still depressingly limiting.“Empowerment” wasn’t always so trivialized, or so corporate, or even so clamorously attached to women.
  • Four decades ago, the word had much more in common with Latin American liberation theology than it did with “Lean In.” In 1968, the Brazilian academic Paulo Freire coined the word “conscientization,” empowerment’s precursor, as the process by which an oppressed person perceives the structural conditions of his oppression and is subsequently able to take action against his oppressors.
  • Eight years later, the educator Barbara Bryant Solomon, writing about American black communities, gave this notion a new name, “empowerment.” It was meant as an ethos for social workers in marginalized communities, to discourage paternalism and encourage their clients to solve problems in their own ways. Then in 1981, Julian Rappaport, a psychologist, broadened the concept into a political theory of power that viewed personal competency as fundamentally limitless; it placed faith in the individual and laid at her feet a corresponding amount of responsibility too.

  • Sneakily, empowerment had turned into a theory that applied to the needy while describing a process more realistically applicable to the rich. The word was built on a misaligned foundation; no amount of awareness can change the fact that it’s the already-powerful who tend to experience empowerment at any meaningful rate. Today “empowerment” invokes power while signifying the lack of it. It functions like an explorer staking a claim on new territory with a white flag.
  • highly marketable “women’s empowerment,” neither practice nor praxis, nor really theory, but a glossy, dizzying product instead. Women’s empowerment borrows the virtuous window-dressing of the social worker’s doctrine and kicks its substance to the side. It’s about pleasure, not power; it’s individualistic and subjective, tailored to insecurity and desire.
  • The new empowerment doesn’t increase potential so much as it assures you that your potential is just fine. Even when the thing being described as “empowering” is personal and mildly defiant (not shaving, not breast-feeding, not listening to men, et cetera), what’s being mar­keted is a certain identity.
  • When consumer purchases aren’t made out to be a path to female empowerment, a branded corporate experience often is. There’s TEDWomen (“about the power of women”), the Forbes Women’s Summit (“#RedefinePower”) and Fortune’s Most Powerful Women Conference (tickets are $10,000).
  • This consumption-and-conference empowerment dilutes the word to pitch-speak, and the concept to something that imitates rather than alters the structures of the world. This version of empowerment can be actively disempowering: It’s a series of objects and experiences you can purchase while the conditions determining who can access and accumulate power stay the same. The ready partici­pation of well-off women in this strat­egy also points to a deep truth about the word “empowerment”: that it has never been defined by the people who actually need it. People who talk empowerment are, by definition, already there.
  • I have never said “empowerment” sincerely or heard it from a single one of my friends. The formulation has been diluted to something representational and bloodless — an architectural rendering of a building that will never be built.But despite its nonexistence in honest conversation, “empowerment” goes on thriving. It’s uniquely marketable, like the female body, which is where women’s empowerment is forced to live.
  • Like Sandberg, Kardashian is the apotheosis of a particular brand of largely contentless feminism, a celebratory form divorced from material politics, which makes it palatable — maybe irresistible — to the business world. Advertisement Continue reading the main story The mistake would be to locate further empowerment in choosing between the two. Corporate empowerment — as well as the lightweight, self-exculpatory feminism it rides on — feeds rav­enously on the distracting performance of identity, that buffet of false opposition.

Science on the Rampage by Freeman Dyson | The New York Review of Books - 0 views

  • science is only a small part of human capability. We gain knowledge of our place in the universe not only from science but also from history, art, and literature. Science is a creative interaction of observation with imagination. “Physics at the Fringe” is what happens when imagination loses touch with observation. Imagination by itself can still enlarge our vision when observation fails. The mythologies of Carter and Velikovsky fail to be science, but they are works of art and high imagining. As William Blake told us long ago, “You never know what is enough unless you know what is more than enough.”
  • Over most of the territory of physics, theorists and experimenters are engaged in a common enterprise, and theories are tested rigorously by experiment. The theorists listen to the voice of nature speaking through experimental tools. This was true for the great theorists of the early twentieth century, Einstein and Heisenberg and Schrödinger, whose revolutionary theories of relativity and quantum mechanics were tested by precise experiments and found to fit the facts of nature. The new mathematical abstractions fit the facts, while the old mechanical models did not.
  • String cosmology is different. String cosmology is a part of theoretical physics that has become detached from experiments. String cosmologists are free to imagine universes and multiverses, guided by intuition and aesthetic judgment alone. Their creations must be logically consistent and mathematically elegant, but they are otherwise unconstrained.

  • The fringe of physics is not a sharp boundary with truth on one side and fantasy on the other. All of science is uncertain and subject to revision. The glory of science is to imagine more than we can prove. The fringe is the unexplored territory where truth and fantasy are not yet disentangled.

New Statesman - All machine and no ghost? - 0 views

  • More subtly, there are many who insist that consciousness just reduces to brain states - a pang of regret, say, is just a surge of chemicals across a synapse. They are collapsers rather than deniers. Though not avowedly eliminative, this kind of view is tacitly a rejection of the very existence of consciousness
  • it occurred to me that the problem might lie not in nature but in ourselves: we just don't have the faculties of comprehension that would enable us to remove the sense of mystery. Ontologically, matter and consciousness are woven intelligibly together but epistemologically we are precluded from seeing how. I used Noam Chomsky's notion of "mysteries of nature" to describe the situation as I saw it. Soon, I was being labelled (by Owen Flanagan) a "mysterian"

  • At this point the idealist swooshes in: ladies and gentlemen, there is nothing but mind! There is no problem of interaction with matter because matter is mere illusion
  • idealism has its charms but taking it seriously requires an antipathy to matter bordering on the maniacal. Are we to suppose that material reality is just a dream, a baseless fantasy, and that the Big Bang was nothing but the cosmic spirit having a mental sneezing fit?
  • pan­psychism: even the lowliest of material things has a streak of sentience running through it, like veins in marble. Not just parcels of organic matter, such as lizards and worms, but also plants and bacteria and water molecules and even electrons. Everything has its primitive feelings and minute allotment of sensation.
  • The trouble with panpsychism is that there just isn't any evidence of the universal distribution of consciousness in the material world.
  • The dualist, by contrast, freely admits that consciousness exists, as well as matter, holding that reality falls into two giant spheres. There is the physical brain, on the one hand, and the conscious mind, on the other: the twain may meet at some point but they remain distinct entities.
  • The more we know of the brain, the less it looks like a device for creating consciousness: it's just a big collection of biological cells and a blur of electrical activity - all machine and no ghost.
  • mystery is quite pervasive, even in the hardest of sciences. Physics is a hotbed of mystery: space, time, matter and motion - none of it is free of mysterious elements. The puzzles of quantum theory are just a symptom of this widespread lack of understanding
  • The human intellect grasps the natural world obliquely and glancingly, using mathematics to construct abstract representations of concrete phenomena, but what the ultimate nature of things really is remains obscure and hidden. How everything fits together is particularly elusive, perhaps reflecting the disparate cognitive faculties we bring to bear on the world (the senses, introspection, mathematical description). We are far from obtaining a unified theory of all being and there is no guarantee that such a theory is accessible by finite human intelligence.
  • real naturalism begins with a proper perspective on our specifically human intelligence. Palaeoanthropologists have taught us that the human brain gradually evolved from ancestral brains, particularly in concert with practical toolmaking, centring on the anatomy of the human hand. This history shaped and constrained the form of intelligence now housed in our skulls (as the lifestyle of other species form their set of cognitive skills). What chance is there that an intelligence geared to making stone tools and grounded in the contingent peculiarities of the human hand can aspire to uncover all the mysteries of the universe? Can omniscience spring from an opposable thumb? It seems unlikely, so why presume that the mysteries of consciousness will be revealed to a thumb-shaped brain like ours?
  • The "mysterianism" I advocate is really nothing more than the acknowledgment that human intelligence is a local, contingent, temporal, practical and expendable feature of life on earth - an incremental adaptation based on earlier forms of intelligence that no one would reg
  • rd as faintly omniscient. The current state of the philosophy of mind, from my point of view, is just a reflection of one evolutionary time-slice of a particular bipedal species on a particular humid planet at this fleeting moment in cosmic history - as is everything else about the human animal. There is more ignorance in it than knowledge.

This Sociological Theory Explains Why Wall Street Is Rigged for Crisis - Bill Davidow -... - 0 views

  • near brush with nuclear catastrophe, brought on by a single foraging bear, is an example of what sociologist Charles Perrow calls a “normal accident.” These frightening incidents are “normal” not because they happen often, but because they are almost certain to occur in any tightly connected complex system.
  • Perrow had a fairly simple solution for the problem. High-risk systems, such as nuclear power plants, should be built only as a last resort.
  • errow stresses the role that human error and mismanagement play in these scenarios. The important lesson: failures in complex systems are caused not only by the hardware and software problems but by people and their motivations.
  • ...4 more annotations...
  • Normal accidents, like these, occur because two or more independent failures happen and interact in unpredictable ways. After studying calamities such as the Three Mile Island meltdown, explosions at chemical plants, and ships colliding in the open sea, Perrow observed that safety mechanisms put in place to make the systems safer in fact frequently trigger the final failure.
  • That solution won’t work for financial markets. We need currency hedges, futures markets, and derivatives to keep our economic systems functioning. But we also have to realize tweaking the current system will not fix the problem. Most of the supposedly strong cures implemented by legislators to date, such as prohibiting bank holding companies from proprietary trading, are inadequate as well.
  • how do we make our markets less danger prone? A good place to start would be to reduce the excessive trading volumes that lie at the root of accidents like the Flash Freeze, Flash Cash, and Goldman debacle. There is no valid reason for high frequency trading to make up more than 50 percent of all stock trades, and there is no pressing need for some $4 trillion in daily foreign currency transactions. A Tobin tax on transactions, first suggested by Noble laureate James Tobin in 1972, of as little as 0.1 percent, would significantly reduce these volumes. Smaller transaction volumes would reduce the size of accidents and possibly their frequency.
  • But tinkering with the current system and looking for easy ways out, as we are now, is bound to fail. We’re in danger of letting normal accidents in the financial system become all too normal.

Scientists Explain their Processes with a little too much honesty - 0 views

    Satirical view of how scientists work; we think scientists use through methods all the time, but can we really know they do?

Inbox Zero vs. Inbox 5,000: A Unified Theory - The Atlantic - 0 views

  • This has led me to a theory that there are two types of emailers in the world: Those who can comfortably ignore unread notifications, and those who feel the need to take action immediately.
  • Gloria Mark, a professor of informatics at University of California, Irvine, has explored just this sort of question. A few years ago, she ran a study in which office workers were cut off from using email for one workweek and were equipped with heart-rate monitors; on average, going cold turkey significantly reduced their stress levels.
  • After interviewing several people about their relationship with email, Mark has noticed that, for some people, email is an extension of autonomy—it's about having control.
  • ...3 more annotations...
  • “It takes people on average about 25 minutes to reorient back to a task when they get interrupted,” she says. Yes, that includes even brief interruptions, like dashing off a quick response to an email, and it often takes so long to get back on task because the project you start doing after handling an email often isn’t the same as the one you were already doing.
  • I happen to like Mark’s theory, but I also think there’s another urge that fuels the nagging feeling that comes with unread messages: Immediately reading and archiving incoming emails is just like checking a box on a to-do list and clearing out unread stories in an RSS feed. In other words, the appeal of these behaviors lies in the illusion of progress that they foster.
  • Jamie Madigan, a psychologist who writes about video games, thinks the arrival of a notification might be similar to the accrual of virtual loot. Email, in other words, might not be just a task, but a game.
