What Architecture Is Doing to Your Brain - CityLab - 1 views

  • Much of the student population would likely agree that the library’s menacing figure on the quad is nothing short of soul-crushing. New research conducted by a team of architects and neuroscientists suggests that architecture may indeed affect mental states, though they choose to focus on the positive.
  • I spoke with Dr. Julio Bermudez, the lead of a new study that uses fMRI to capture the effects of architecture on the brain. His team operates with the goal of using the scientific method to transform something opaque—the qualitative “phenomenologies of our built environment”—into neuroscientific observations that architects and city planners can deliberately design for. Bermudez and his team’s research question focuses on buildings and sites designed to elicit contemplation: They theorize that the presence of “contemplative architecture” in one’s environment may over time produce the same health benefits as traditional “internally induced” meditation, except with much less effort by the individual.
  • By showing 12 architects photos of contemplative and non-contemplative buildings from facade to interior, the researchers were able to observe the brain activity that occurred as subjects "imagined they were transported to the places being shown." All of the architects were white, right-handed men with no prior meditative training, creating the necessary (if comical) uniformity for neuroscientific research—the team wanted to ensure that the brain scans would not be influenced by factors unrelated to the photos, like gender, race, or handedness. For instance, the brain scans of left- and right-handed people often look different even when subjects are performing the same task.

  • In addition to posing an interesting control on the experiment, the decision to use architects was a strategic one meant to increase the researchers’ chances of achieving conclusive results. Though everyone encounters architecture, studies on the built environment struggle for funding because, as Bermudez remarked with a sigh, “it’s difficult to suggest that people are dying from it.” Architects were a natural choice for the pilot study because, the team reasoned, their critical training and experience would make them sensitive to features of the buildings that a lay person might overlook.
  • they deployed online surveys in Spanish and English to gather testimony on extraordinary architectural experiences (EAEs), or encounters with places that fundamentally alter one’s normal state of being. Critically, most of the buildings or sites mentioned in the 2,982 testimonies were designed with contemplation in mind, whether spiritual, aesthetic, religious, or symbolic, leading the researchers to conclude that “buildings may induce insightful, profound, and transformative contemplative states, [and] buildings designed to provoke contemplation seem to be succeeding”
  • Anticipating skeptics who would claim that these experiences are subjective, the researchers expanded the question to draw on the established neuroscientific subfield of meditation, with some important differences. Related studies to date have focused on internally produced states that are easily replicated in the lab, and on aesthetic evaluation, or the activity that occurs in the orbital frontal cortex as we make snap judgments about whether we find things ugly or beautiful.
  • Bermudez and his team expected that architecturally induced contemplative states would be strong, non-evaluative aesthetic experiences— eliciting more activity in areas associated with emotion and pleasure, but less activity in the orbital frontal cortex.
  • The presence of an external stimulus (the photos of the buildings) also removes the tedious self-regulation that occurs in the prefrontal cortex during traditional meditation. The interviews of the 12 subjects revealed that “peacefulness and relaxation, lessening of mind wandering, increasing of attention, and deepening of experience” were all common effects of viewing the photos—also common was a slight element of aesthetic judgment, seemingly inescapable in the crowd of critics.
  • The provisional conclusions of the study are that the brain behaves differently when exposed to contemplative and non-contemplative buildings, contemplative states elicited through “architectural aesthetics” are similar to the contemplation of traditional meditation in some ways, and different in other ways, and, finally, that “architectural design matters.”
  • reinforces a growing trend in architecture and design as researchers are beginning to study how the built environment affects the people who live in it. ANFA proclaims that “some observers have characterized what is happening in neuroscience as the most exciting frontier of human discovery since the Renaissance.”
  • gritty details: the optimal ceiling heights for different cognitive functions; the best city design for eliciting our natural exploratory tendencies and making way-finding easier; the ideal hospital layout to improve memory-related tasks in patients recovering from certain brain injuries; the influence of different types and quantities of light within a built space on mood and performance.

Here's what the government's dietary guidelines should really say - The Washington Post - 0 views

  • If I were writing the dietary guidelines, I would give them a radical overhaul. I’d go so far as to radically overhaul the way we evaluate diet. Here’s why and how.
  • Lately, as scientists try, and fail, to reproduce results, all of science is taking a hard look at funding biases, statistical shenanigans and groupthink. All that criticism, and then some, applies to nutrition.
  • Prominent in the charge to change the way we do science is John Ioannidis, professor of health research and policy at Stanford University. In 2005, he published “Why Most Research Findings Are False” in the journal PLOS Medicin
  • ...15 more annotations...
  • He came down hard on nutrition in a pull-no-punches 2013 British Medical Journal editorial titled, “Implausible results in human nutrition research,” in which he noted, “Almost every single nutrient imaginable has peer reviewed publications associating it with almost any outcome.”
  • Ioannidis told me that sussing out the connection between diet and health — nutritional epidemiology — is enormously challenging, and “the tools that we’re throwing at the problem are not commensurate with the complexity and difficulty of the problem.” The biggest of those tools is observational research, in which we collect data on what people eat, and track what happens to them.
  • Give tens of thousands of people that FFQ, and you end up with a ginormous repository of possible correlations. You can zero in on a vitamin, macronutrient or food, and go to town. But not only are you starting with flawed data, you’ve got a zillion possible confounding variables — dietary, demographic, socioeconomic. I’ve heard statisticians call it “noise mining,” and Ioannidis is equally skeptical. “With this type of data, you can get any result you want,” he said. “You can align it to your beliefs.”
  • funding bias isn’t the only kind. “Fanatical opinions abound in nutrition,” Ioannidis wrote in 2013, and those have bias power too.
  • “Definitive solutions won’t come from another million observational papers or small randomized trials,” reads the subtitle of Ioannidis’s paper. His is a burn-down-the-house ethos.
  • When it comes to actual dietary recommendations, the disagreement is stark. “Ioannidis and others say we have no clue, the science is so bad that we don’t know anything,” Hu told me. “I think that’s completely bogus. We know a lot about the basic elements of a healthy diet.”
  • He lists plant-based foods — fruit, veg, whole grains, legumes — but acknowledges that we don’t understand enough to prescribe specific combinations or numbers of servings.
  • Big differences in what people eat track with other differences. Heavy plant-eaters are different from, say, heavy meat-eaters in all kinds of ways (income, education, physical activity, BMI). Red meat consumption correlates with increased risk of dying in an accident as much as dying from heart disease. The amount of faith we put in observational studies is a judgment call.
  • I find myself in Ioannidis’s camp. What have we learned, unequivocally enough to build a consensus in the nutrition community, about how diet affects health? Well, trans-fats are bad.
  • Over and over, large population studies get sliced and diced, and it’s all but impossible to figure out what’s signal and what’s noise. Researchers try to do that with controlled trials to test the connections, but those have issues too. They’re expensive, so they’re usually small and short-term. People have trouble sticking to the diet being studied. And scientists are generally looking for what they call “surrogate endpoints,” like increased cholesterol rather than death from heart disease, since it’s impractical to keep a trial going until people die.
  • , what do we do? Hu and Ioannidis actually have similar suggestions. For starters, they both think we should be looking at dietary patterns rather than single foods or nutrients. They also both want to look across the data sets. Ioannidis emphasizes transparency. He wants to open data to the world and analyze all the data sets in the same way to see if “any signals survive.” Hu is more cautious (partly to safeguard confidentiality
  • I have a suggestion. Let’s give up on evidence-based eating. It’s given us nothing but trouble and strife. Our tools can’t find any but the most obvious links between food and health, and we’ve found those already.
  • Instead, let’s acknowledge the uncertainty and eat to hedge against what we don’t know
  • We’ve got two excellent hedges: variety and foods with nutrients intact (which describes such diets as the Mediterranean, touted by researchers). If you severely limit your foods (vegan, keto), you might miss out on something. Ditto if you eat foods with little nutritional value (sugar, refined grains). Oh, and pay attention to the two things we can say with certainty: Keep your weight down, and exercise.
  • I used to say I could tell you everything important about diet in 60 seconds. Over the years, my spiel got shorter and shorter as truisms fell by the wayside, and my confidence waned in a field where we know less, rather than more, over time. I’m down to five seconds now: Eat a wide variety of foods with their nutrients intact, keep your weight down and get some exercise.

A New Dark Age Looms - The New York Times - 1 views

  • picture yourself in our grandchildren’s time, a century hence. Significant global warming has occurred, as scientists predicted. Nature’s longstanding, repeatable patterns — relied on for millenniums by humanity to plan everything from infrastructure to agriculture — are no longer so reliable. Cycles that have been largely unwavering during modern human history are disrupted by substantial changes in temperature and precipitation.
  • As Earth’s warming stabilizes, new patterns begin to appear. At first, they are confusing and hard to identify. Scientists note similarities to Earth’s emergence from the last ice age. These new patterns need many years — sometimes decades or more — to reveal themselves fully, even when monitored with our sophisticated observing systems
  • Disruptive societal impacts will be widespread.
  • ...9 more annotations...
  • Our foundation of Earth knowledge, largely derived from historically observed patterns, has been central to society’s progress. Early cultures kept track of nature’s ebb and flow, passing improved knowledge about hunting and agriculture to each new generation. Science has accelerated this learning process through advanced observation methods and pattern discovery techniques. These allow us to anticipate the future with a consistency unimaginable to our ancestors.
  • But as Earth warms, our historical understanding will turn obsolete faster than we can replace it with new knowledge. Some patterns will change significantly; others will be largely unaffected
  • The list of possible disruptions is long and alarming.
  • Historians of the next century will grasp the importance of this decline in our ability to predict the future. They may mark the coming decades of this century as the period during which humanity, despite rapid technological and scientific advances, achieved “peak knowledge” about the planet it occupies
  • One exception to this pattern-based knowledge is the weather, whose underlying physics governs how the atmosphere moves and adjusts. Because we understand the physics, we can replicate the atmosphere with computer models.
  • But farmers need to think a season or more ahead. So do infrastructure planners as they design new energy and water systems
  • The intermediate time period is our big challenge. Without substantial scientific breakthroughs, we will remain reliant on pattern-based methods for time periods between a month and a decade. The problem is, as the planet warms, these patterns will become increasingly difficult to discern.
  • The oceans, which play a major role in global weather patterns, will also see substantial changes as global temperatures rise. Ocean currents and circulation patterns evolve on time scales of decades and longer, and fisheries change in response. We lack reliable, physics-based models to tell us how this occurs.
  • Our grandchildren could grow up knowing less about the planet than we do today. This is not a legacy we want to leave them. Yet we are on the verge of ensuring this happens.

The Reality of Quantum Weirdness - NYTimes.com - 1 views

  • Is there a true story, or is our belief in a definite, objective, observer-independent reality an illusion?
  • a paper published online in the journal Nature Physics presents experimental research that supports the latter scenario — that there is a “Rashomon effect” not just in our descriptions of nature, but in nature itself.
  • The electron appears to be a strange hybrid of a wave and a particle that’s neither here and there nor here or there. Like a well-trained actor, it plays the role it’s been called to perform
  • ...8 more annotations...
  • Is nature really this weird? Or is this apparent weirdness just a reflection of our imperfect knowledge of nature?
  • The answer depends on how you interpret the equations of quantum mechanics, the mathematical theory that has been developed to describe the interactions of elementary particles. The success of this theory is unparalleled: Its predictions, no matter how “spooky,” have been observed and verified with stunning precision. It has also been the basis of remarkable technological advances. So it is a powerful tool. But is it also a picture of reality?
  • Does the wave function directly correspond to an objective, observer-independent physical reality, or does it simply represent an observer’s partial knowledge of it?
  • If there is an objective reality at all, the paper demonstrates, then the wave function is in fact reality-based.
  • What this research implies is that we are not just hearing different “stories” about the electron, one of which may be true. Rather, there is one true story, but it has many facets, seemingly in contradiction, just like in “Rashomon.” There is really no escape from the mysterious — some might say, mystical — nature of the quantum world.
  • We should be careful to recognize that the weirdness of the quantum world does not directly imply the same kind of weirdness in the world of everyday experience.
  • This is why, in fact, we are able to describe the objects around us in the language of classical physics.
  • I suggest that we regard the paradoxes of quantum physics as a metaphor for the unknown infinite possibilities of our own existence.

Suhas Dara Blogs: "All knowledge depends on the recognition of patterns and anomalies."... - 0 views

  • In the study of TOK in DP-1 (11th grade), I have learnt about the ways of knowing, and two of the areas of knowledge - natural sciences and human sciences. Of all the discussions and explorations done into these areas of knowledge, there can be patterns observed in the methods of experimentation, data collection, data analysis and also assumptions being made when generalizing situations. In some of the above points, human sciences is similar to natural sciences, while in the others, the ideologies and working is different.
  • Natural sciences and human sciences for instance both use experiments as a form of data collection but the methods and outputs are different. Natural scientists have lesser moral values to take care of compared to human scientists such as psychologists. Psychologists are directly dealing with humans and hence need to take more ethical implications into consideration. Secondly, human scientists conduct experiments on a large set of people - not limited to one race or gender unless it is required. Natural scientists do not require survey type data. Here, a single scientist conducts the experiments. Both the types of experiments are empirical based though, direct experimentation is more in natural sciences while human sciences are more observation based. But experiments in human sciences have more unpredictable results due to what is known as the Hawthorne effect. This effect explains that when a particular group comes to know that they are under observation for a experiment or an analysis, they tend to be more productive. These cause errors in results of human science experiments especially the ones of psychology.

Scientists are baffled: What's up with the universe? - The Washington Post - 0 views

  • The universe is unimaginably big, and it keeps getting bigger. But astronomers cannot agree on how quickly it is growing — and the more they study the problem, the more they disagree.
  • Some scientists call this a “crisis” in cosmology. A less dramatic term in circulation is “the Hubble Constant tension.”
  • Nine decades ago, the astronomer Edwin Hubble showed that the universe is orders of magnitude vaster than previously imagined — and the whole kit and kaboodle is expanding. The rate of that expansion is a number called the Hubble Constant.
  • ...12 more annotations...
  • It’s a slippery number, however. Measurements using different techniques have produced different results, and the numbers show no sign of converging even as researchers refine their observations
  • the theorists are intrigued. They hope the Hubble Constant confusion is the harbinger of a potential major discovery — some "new physics."
  • “Any time there’s a discrepancy, some kind of anomaly, we all get very excited,”
  • “Where’s it all going to go? How’s it all going to end? That’s a big question,”
  • One idea floating around is that there could have been something called Early Dark Energy that skewed the appearance of the background radiation
  • “New physics might be that there’s some form of energy that acted in the earliest moments of the evolution of the universe. You’d get an injection of energy that’d then have to disappear,”
  • Leavitt, a then-obscure employee of the Harvard College Observatory, discovered that the intrinsically brighter stars have longer periods. This insight — Leavitt’s law — allows astronomers to know the Cepheid’s absolute luminosity, then gauge the distance to the star based on how bright or faint it appears.
  • just to be clear: The Hubble Constant in question is the rate of expansion in our “local” universe, not the rate of expansion when the background radiation was first emitted billions of years ago. Over time, the Hubble Constant isn’t constant.)
  • At the dawn of the 21st century, this Standard Model seemed to pass every observational test. And any disparities in the measurement of the Hubble Constant would surely be ironed out with further observations, scientists assumed. They had even nailed down the age of the universe precisely: 13.8 billion years.
  • “We felt really good,”
  • He added, jokingly, “We should have stopped taking data.”
  • “We are wired to use our intuition to understand things around us,” Riess said. “Most of the universe is made out of stuff that’s completely different than us. This adherence to intuition is often wildly unsuccessful in the universe.”

The Importance of a Positive Classroom - 0 views

  • The Importance of a Positive Classroom
  • Simply put, students learn better when they view the learning environment as positive and supportive

  • ...16 more annotations...
  • Such an environment provides relevant content, clear learning goals and feedback, opportunities to build social skills, and strategies to help students succeed
  • We all know the factors that can threaten a positive classroom environment: problems that kids bring from home, lack of motivation among students whose love of learning has been drilled right out of them, pressures from testing, and more
  • We can't control all these factors, but what if we could implement some simple strategies to buffer against their negative effects?
  • We can foster effective learning and transform the experience of our students every day by harnessing the power of emotions.
  • don't worry: I'm not talking about holding a daily class meeting to talk about feelings.
  • Stress, for example, has a significant negative effect on cognitive functioning
  • Unfortunately, when it comes to learning processes, the power of negative events greatly outweighs the power of positive event
  • As a result, we need to prepare ourselves with an arsenal of strategies that inoculate our students against the power of negativity.
  • By providing enough positive experiences to counteract the negative, we can help students avoid getting stuck in a "negative spiral"
  • Being caught up in negative emotions in this way impairs learning by narrowing students' focus and inhibiting their ability to see multiple viewpoints and solve problems.
  • This publication is not a cheat sheet, a "happyology" manual, or a Band-Aid that will fix that distressed kid and send him to a magical haven of learning.
  • Far from promising easy solutions and instant results, these strategies will increase students' capacity to tolerate the discomfort that comes with working hard and to accept that there are no easy answers—that only critical thinking and perseverance lead the way to mastery.
  • pause every 10 minutes and simply observe how many students are actively engaged and how many are off task.
  • If it is too challenging to chart the behavior of each student, you can choose a sample of the class to observe.
  • Remember to keep a full observation stance, and try not to leap to judgment. Keep in mind various "factors of mass distraction" that may contribute to problems , such as people entering or leaving the room, noise level, students' seating locations, and time of day. You might also want to note the affect or mood of students as they come into class that day.
  • As for the less productive moments you identify, the following strategies will help you create an environment that is more conducive to engagement and learning.

Probing the Secrets of Jupiter's Great Red Spot - 0 views

  • In technical terms, the Great Red Spot is an anticyclonic storm lying in a high-pressure zone high in Jupiter's clouds. It rotates counter-clockwise and takes about six Earth days to make one complete trip around the planet. It has clouds embedded within it, which often tower many kilometers above the surrounding cloud decks. Jet streams to its north and south help keep the spot at the same latitude as it circulates.
  • Observers have studied the gas giant planet Jupiter since antiquity. However, they've only been able to observe such a giant spot for a few centuries since it was first discovered. Ground-based observations allowed scientists to chart the motions of the spot, but a true understanding was only made possible by spacecraft flybys. The Voyager 1 spacecraft raced by in 1979 and sent back the first close-up image of the spot. Voyager 2, Galileo, and Juno also provided images.
  • Scientists have been able to measure the spot's depth using specialized instruments on the Juno spacecraft. It appears to be some 300 kilometers deep. That's much deeper than any of Earth's oceans, the deepest of which is just over 10 kilometers. Interestingly, the "roots" of the Great Red Spot are warmer at the bottom (or the base) than at the top. This warmth feeds the incredibly strong and fast winds at the top of the spot, which can blow more than 430 kilometers per hour. Warm winds feeding a strong storm is a well-understood phenomenon on Earth, particularly in massive hurricanes. Above the cloud, temperatures rise again, and scientists are working to understand why this is happening. In that sense, then, the Great Red Spot is a Jupiter-style hurricane.

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?

Good News, Bad News: The Universe Next Door : 13.7: Cosmos And Culture : NPR - 0 views

  • Welcome to cosmic catastrophism
  • universe began its existence 13.7 billion years ago and has been expanding ever since.
  • xpansion wasn't always at the same rate.
  • ...9 more annotations...
  • our whole universe could have emerged from a tiny patch of space that was stretched like a rubber band by the enormous factor of one hundred trillion trillion times (1026) in a fraction of a second. The universe we observe today fits within this stretched region, like an island in an ocean.
  • imagine that other portions of space, neighbors to that tiny patch that gave rise to our universe, also got stretched at different rates and at different times. We would have a universe filled with island-universes, each with its own history and possibly even types of matter, etc. This ocean of island-universes is called the multiverse.

  • hysics is an empirical science
  • Cosmic inflation predicts that our universe is geometrically flat (or almost) like the surface of a table but in three dimensions; it also predicts that space should be filled with radiation with a uniform temperature, as bathwater fills a bathtub
  • Since we can't receive information from outside our universe (or better, from outside our "horizon", the sphere that delimits how far light travelled in 13.7 billion years), how can we possibly test the existence of other universes "out there"?
  • However, we can do the next best thing, and see if at least neighboring universes exist. Just as with soap bubbles that vibrate when they collide with one another without popping, if another universe collided with ours in the distant past, the radiation inside our universe would have vibrated in response to the perturbations caused by the collision.
  • The bad news is that the probability of a collision with another universe increases with time: we could disappear at any instant: live life to the fullest!
  • The good news is that, although the multiverse as a whole may not be a testable scientific hypothesis, with some luck we may at least know if one or a few other universes exist. An observational test distinguishes science from idle speculation.

Science and gun violence: why is the research so weak? [Part 2] - Boing Boing - 1 views

  • Scientists are missing some important bits of data that would help them better understand the effects of gun policy and the causes of gun-related violence. But that’s not the only reason why we don’t have solid answers. Once you have the data, you still have to figure out what it means. This is where the research gets complicated, because the problem isn’t simply about what we do and don’t know right now. The problem, say some scientists, is that we —from the public, to politicians, to even scientists themselves—may be trying to force research to give a type of answer that we can’t reasonably expect it to offer. To understand what science can do for the gun debates, we might have to rethink what “evidence-based policy” means to us.
  • For the most part, there aren’t a lot of differences in the data that these studies are using. So how can they reach such drastically different conclusions? The issue is in the kind of data that exists, and what you have to do to understand it, says Charles Manski, professor of economics at Northwestern University. Manski studies the ways that other scientists do research and how that research translates into public policy.
  • Even if we did have those gaps filled in, Manski said, what we’d have would still just be observational data, not experimental data. “We don’t have randomized, controlled experiments, here,” he said. “The only way you could do that, you’d have to assign a gun to some people randomly at birth and follow them throughout their lives. Obviously, that’s not something that’s going to work.”
  • ...14 more annotations...
  • This means that, even under the best circumstances, scientists can’t directly test what the results of a given gun policy are. The best you can do is to compare what was happening in a state before and after a policy was enacted, or to compare two different states, one that has the policy and one that doesn’t. And that’s a pretty inexact way of working.
  • Add in enough assumptions, and you can eventually come up with an estimate. But is the estimate correct? Is it even close to reality? That’s a hard question to answer, because the assumptions you made—the correlations you drew between cause and effect, what you know and what you assume to be true because of that—might be totally wrong.
  • It’s hard to tease apart the effect of one specific change, compared to the effects of other things that could be happening at the same time.
  • This process of taking the observational data we do have and then running it through a filter of assumptions plays out in the real world in the form of statistical modeling. When the NAS report says that nobody yet knows whether more guns lead to more crime, or less crime, what they mean is that the models and the assumptions built into those models are all still proving to be pretty weak.
  • From either side of the debate, he said, scientists continue to produce wildly different conclusions using the same data. On either side, small shifts in the assumptions lead the models to produce different results. Both factions continue to choose sets of assumptions that aren’t terribly logical. It’s as if you decided that anybody with blue shoes probably had a belly-button piercing. There’s not really a good reason for making that correlation. And if you change the assumption—actually, belly-button piercings are more common in people who wear green shoes—you end up with completely different results.
  • The Intergovernmental Panel on Climate Change (IPCC) produces these big reports periodically, which analyze lots of individual papers. In essence, they’re looking at lots of trees and trying to paint you a picture of the forest. IPCC reports are available for free online, you can go and read them yourself. When you do, you’ll notice something interesting about the way that the reports present results. The IPCC never says, “Because we burned fossil fuels and emitted carbon dioxide into the atmosphere then the Earth will warm by x degrees.” Instead, those reports present a range of possible outcomes … for everything. Depending on the different models used, different scenarios presented, and the different assumptions made, the temperature of the Earth might increase by anywhere between 1.5 and 4.5 degrees Celsius.
  • What you’re left with is an environment where it’s really easy to prove that your colleague’s results are probably wrong, and it’s easy for him to prove that yours are probably wrong. But it’s not easy for either of you to make a compelling case for why you’re right.
  • Statistical modeling isn’t unique to gun research. It just happens to be particularly messy in this field. Scientists who study other topics have done a better job of using stronger assumptions and of building models that can’t be upended by changing one small, seemingly randomly chosen detail. It’s not that, in these other fields, there’s only one model being used, or even that all the different models produce the exact same results. But the models are stronger and, more importantly, the scientists do a better job of presenting the differences between models and drawing meaning from them.
  • “Climate change is one of the rare scientific literatures that has actually faced up to this,” Charles Manski said. What he means is that, when scientists model climate change, they don’t expect to produce exact, to-the-decimal-point answers.
  • “It’s been a complete waste of time, because we can’t validate one model versus another,” Pepper said. Most likely, he thinks that all of them are wrong. For instance, all the models he’s seen assume that a law will affect every state in the same way, and every person within that state in the same way. “But if you think about it, that’s just nonsensical,” he said.
  • On the one hand, that leaves politicians in a bit of a lurch. The response you might mount to counteract a 1.5 degree increase in global average temperature is pretty different from the response you’d have to 4.5 degrees. On the other hand, the range does tell us something valuable: the temperature is increasing.
  • The problem with this is that it flies in the face of what most of us expect science to do for public policy. Politics is inherently biased, right? The solutions that people come up with are driven by their ideologies. Science is supposed to cut that Gordian Knot. It’s supposed to lay the evidence down on the table and impartially determine who is right and who is wrong.
  • Manski and Pepper say that this is where we need to rethink what we expect science to do. Science, they say, isn’t here to stop all political debate in its tracks. In a situation like this, it simply can’t provide a detailed enough answer to do that—not unless you’re comfortable with detailed answers that are easily called into question and disproven by somebody else with a detailed answer.
  • Instead, science can reliably produce a range of possible outcomes, but it’s still up to the politicians (and, by extension, up to us) to hash out compromises between wildly differing values on controversial subjects. When it comes to complex social issues like gun ownership and gun violence, science doesn’t mean you get to blow off your political opponents and stake a claim on truth. Chances are, the closest we can get to the truth is a range that encompasses the beliefs of many different groups.

Lessons from Playing Golf with Trump - The New Yorker - 1 views

  • “I will buy one only if it has the potential to be the best. I’m not interested in having a nine.”
  • A friend asked me later whether Trump wasn’t “in on the joke” of his public persona, and I said that, as far as I could tell, the Trump we were used to seeing on television was the honest-to-god authentic Trump: a ten-year-old boy who, for unknown reasons, had been given a real airplane and a billion dollars. In other words, a fun guy to hang around with.
  • He was upset that I hadn’t written that he’d shot 71—a very good golf score, one stroke under par.
  • ...3 more annotations...
  • He complained to me that golf publications never rank his courses high enough, because the people who do the rating hold a grudge against him, but he also said that he never allows raters to play his courses, because they would just get in the way of the members.
  • He wanted the number, and the fact that I hadn’t published the number proved that I was just like all the other biased reporters, who, because we’re all part of the anti-Trump media conspiracy, never give him as much credit as he deserves for being awesome.
  • In Trump’s own mind, I suspect, he really did shoot 71 that day, if not (by now) 69. Trump’s world is a parallel universe in which truth takes many forms, none of them necessarily based on reality.
  •  
    I think this article has a very interesting interpretation on Trump's personalities and behaviors. Something we think is absurd might be totally normal in other people's perspective. For example, in this article, the author states that Trump values social status and potential profit more than the real person or the real thing. It shows how people see this world differently and this affects how they make their moves and decisions. I think the overwhelming critics on Trump is partly because we don't understand Trump and don't even try to understand and accept him. He is an anomaly. Also, I think everybody observe the universe through their unique senses and perception, so we cannot tell whose reality is truer than others. Condemning others' reality won't bring us a good negotiation. --Sissi (1/14/2017)

Coping with Chaos in the White House - Medium - 0 views

  • I am not a professional and this is not a diagnosis. My post is not intended to persuade anyone or provide a comprehensive description of NPD. I am speaking purely from decades of dealing with NPD and sharing strategies that were helpful for me in coping and predicting behavior.
  • Here are a few things to keep in mind:
  • 1) It’s not curable and it’s barely treatable. He is who he is. There is no getting better, or learning, or adapting. He’s not going to “rise to the occasion” for more than maybe a couple hours. So just put that out of your mind.
  • ...11 more annotations...
  • 2) He will say whatever feels most comfortable or good to him at any given time. He will lie a lot, and say totally different things to different people. Stop being surprised by this. While it’s important to pretend “good faith” and remind him of promises, as Bernie Sanders and others are doing, that’s for his supporters, so *they* can see the inconsistency as it comes. He won’t care. So if you’re trying to reconcile or analyze his words, don’t. It’s 100% not worth your time. Only pay attention to and address his actions.
  • 3) You can influence him by making him feel good. There are already people like Bannon who appear ready to use him for their own ends. The GOP is excited to try. Watch them, not him.
  • 4) Entitlement is a key aspect of the disorder. As we are already seeing, he will likely not observe traditional boundaries of the office. He has already stated that rules don’t apply to him. This particular attribute has huge implications for the presidency and it will be important for everyone who can to hold him to the same standards as previous presidents.
  • 5) We should expect that he only cares about himself and those he views as extensions of himself, like his children. (People with NPD often can’t understand others as fully human or distinct.) He desires accumulation of wealth and power because it fills a hole.
  • He will have no qualms *at all* about stealing everything he can from the country, and he’ll be happy to help others do so, if they make him feel good. He won’t view it as stealing but rather as something he’s entitled to do. This is likely the only thing he will intentionally accomplish.
  • 6) It’s very, very confusing for non-disordered people to experience a disordered person with NPD. While often intelligent, charismatic and charming, they do not reliably observe social conventions or demonstrate basic human empathy. It’s very common for non-disordered people to lower their own expectations and try to normalize the behavior. DO NOT DO THIS
  • 7) People with NPD often recruit helpers, referred to in the literature as “enablers” when they allow or cover for bad behavior and “flying monkeys” when they perpetrate bad behavior
  • 8) People with NPD often foster competition for sport in people they control. Expect lots of chaos, firings and recriminations. He will probably behave worst toward those closest to him, but that doesn’t mean (obviously) that his actions won’t have consequences for the rest of us. He will punish enemies.
  • 9) Gaslighting — where someone tries to convince you that the reality you’ve experienced isn’t true — is real and torturous. He will gaslight, his followers will gaslight.
  • Learn the signs and find ways to stay focused on what you know to be true. Note: it is typically not helpful to argue with people who are attempting to gaslight. You will only confuse yourself. Just walk away.
  • 10) Whenever possible, do not focus on the narcissist or give him attention. Unfortunately we can’t and shouldn’t ignore the president, but don’t circulate his tweets or laugh at him — you are enabling him and getting his word out.

To Make the World Better, Think Small - The New York Times - 0 views

  • There is a solution, however, to psychic numbing: Think small. In the fund-raising business, there’s an old axiom that “one is greater than one million.” This isn’t bad math; it is a reminder that when it comes to people in need, one million is a statistic, while one is a human story.
  • As we head into 2017, do you want a solution better than “Screw ’em”? Maybe your problem is that you are thinking too big. This year, start with one, not one million. It might just be a happy new year after all.
  •  
    I have once read about a story of a marathon runner. He overcome all the tiresome and pain by setting small goal throughout the long course. He would observe the course beforehand and memorize some significant symbols on the course. By having those small goals, it can release some mental pressure and make the course more approachable. I think this an example of deceiving our brain for good. --Sissi (12/31/2016)

Why Our Children Don't Think There Are Moral Facts - NYTimes.com - 1 views

  • I already knew that many college-aged students don’t believe in moral facts.
  • the overwhelming majority of college freshman in their classrooms view moral claims as mere opinions that are not true or are true only relative to a culture.
  • where is the view coming from?
  • ...32 more annotations...
  • the Common Core standards used by a majority of K-12 programs in the country require that students be able to “distinguish among fact, opinion, and reasoned judgment in a text.”
  • So what’s wrong with this distinction and how does it undermine the view that there are objective moral facts?
  • For example, many people once thought that the earth was flat. It’s a mistake to confuse truth (a feature of the world) with proof (a feature of our mental lives)
  • Furthermore, if proof is required for facts, then facts become person-relative. Something might be a fact for me if I can prove it but not a fact for you if you can’t. In that case, E=MC2 is a fact for a physicist but not for me.
  • worse, students are taught that claims are either facts or opinions. They are given quizzes in which they must sort claims into one camp or the other but not both. But if a fact is something that is true and an opinion is something that is believed, then many claims will obviously be both
  • How does the dichotomy between fact and opinion relate to morality
  • Kids are asked to sort facts from opinions and, without fail, every value claim is labeled as an opinion.
  • Here’s a little test devised from questions available on fact vs. opinion worksheets online: are the following facts or opinions? — Copying homework assignments is wrong. — Cursing in school is inappropriate behavior. — All men are created equal. — It is worth sacrificing some personal liberties to protect our country from terrorism. — It is wrong for people under the age of 21 to drink alcohol. — Vegetarians are healthier than people who eat meat. — Drug dealers belong in prison.
  • The answer? In each case, the worksheets categorize these claims as opinions. The explanation on offer is that each of these claims is a value claim and value claims are not facts. This is repeated ad nauseum: any claim with good, right, wrong, etc. is not a fact.
  • In summary, our public schools teach students that all claims are either facts or opinions and that all value and moral claims fall into the latter camp. The punchline: there are no moral facts. And if there are no moral facts, then there are no moral truths.
  • It should not be a surprise that there is rampant cheating on college campuses: If we’ve taught our students for 12 years that there is no fact of the matter as to whether cheating is wrong, we can’t very well blame them for doing so later on.
  • If it’s not true that it’s wrong to murder a cartoonist with whom one disagrees, then how can we be outraged? If there are no truths about what is good or valuable or right, how can we prosecute people for crimes against humanity? If it’s not true that all humans are created equal, then why vote for any political system that doesn’t benefit you over others?
  • the curriculum sets our children up for doublethink. They are told that there are no moral facts in one breath even as the next tells them how they ought to behave.
  • Our children deserve a consistent intellectual foundation. Facts are things that are true. Opinions are things we believe. Some of our beliefs are true. Others are not. Some of our beliefs are backed by evidence. Others are not.
  • Value claims are like any other claims: either true or false, evidenced or not.
  • The hard work lies not in recognizing that at least some moral claims are true but in carefully thinking through our evidence for which of the many competing moral claims is correct.
  • Moral truths are not the same as scientific truths or mathematical truths. Yet they may still be used a guiding principle for our individual lives as well as our laws.But there is equal danger of giving moral judgments the designation of truth as there is in not doing so. Many people believe that abortion is murder on the same level as shooting someone with a gun. But many others do not. So is it true that abortion is murder?Moral principles can become generally accepted and then form the basis for our laws. But many long accepted moral principles were later rejected as being faulty. "Separate but equal" is an example. Judging homosexual relationships as immoral is another example.
  • Whoa! That Einstein derived an equation is a fact. But the equation represents a theory that may have to be tweaked at some point in the future. It may be a fact that the equation foretold the violence of atomic explosions, but there are aspects of nature that elude the equation. Remember "the theory of everything?"
  • Here is a moral fact, this is a sermon masquerading as a philosophical debate on facts, opinions and truth. This professor of religion is asserting that the government via common core is teaching atheism via the opinion vs fact.He is arguing, in a dishonest form, that public schools should be teaching moral facts. Of course moral facts is code for the Ten Commandments.
  • As a fourth grade teacher, I try to teach students to read critically, including distinguishing between facts and opinions as they read (and have been doing this long before the Common Core arrived, by the way). It's not always easy for children to grasp the difference. I can only imagine the confusion that would ensue if I introduced a third category -- moral "facts" that can't be proven but are true nonetheless!
  • horrible acts occur not because of moral uncertainty, but because people are too sure that their views on morality are 100% true, and anyone who fails to recognize and submit themselves are heathens who deserve death.I can't think of any case where a society has suffered because people are too thoughtful and open-minded to different perspectives on moral truth.In any case, it's not an elementary school's job to teach "moral truths."
  • The characterization of moral anti-realism as some sort of fringe view in philosophy is misleading. Claims that can be true or false are, it seems, 'made true' by features of the world. It's not clear to many in philosophy (like me) just what features of the world could make our moral claims true. We are more likely to see people's value claims as making claims about, and enforcing conformity to, our own (contingent) social norms. This is not to hold, as Mr. McBrayer seems to think follows, that there are no reasons to endorse or criticize these social norms.
  • This is nonsense. Giving kids the tools to distinguish between fact and opinion is hard enough in an age when Republicans actively deny reality on Fox News every night. The last thing we need is to muddy their thinking with the concept of "moral facts."A fact is a belief that everyone _should_ agree upon because it is observable and testable. Morals are not agreed upon by all. Consider the hot button issue of abortion.
  • Truthfully, I'm not terribly concerned that third graders will end up taking these lessons in the definition of fact versus opinion to the extremes considered here, or take them as a license to cheat. That will come much later, when they figure out, as people always have, what they can get a way with. But Prof. McBrayer, with his blithe expectation that all the grownups know that there moral "facts"? He scares the heck out of me.
  • I've long chafed at the language of "fact" v. "opinion", which is grounded in a very particular, limited view of human cognition. In my own ethics courses, I work actively to undermine the distinction, focusing instead on considered judgment . . . or even more narrowly, on consideration itself. (See http://wp.me/p5Ag0i-6M )
  • The real waffle here is the very concept of "moral facts." Our statements of values, even very important ones are, obviously, not facts. Trying to dress them up as if they are facts, to me, argues for a pretty serious moral weakness on the part of those advancing the idea.
  • Our core values are not important because they are facts. They are important because we collectively hold them and cherish them. To lean on the false crutch of "moral facts" to admit the weakness of your own moral convictions.
  • I would like to believe that there is a core of moral facts/values upon which all humanity can agree, but it would be tough to identify exactly what those are.
  • For the the ancient philosophers, reality comprised the Good, the True, and the Beautiful (what we might now call ethics, science and art), seeing these as complementary and inseparable, though distinct, realms. With the ascendency of science in our culture as the only valid measure of reality to the detriment of ethics and art (that is, if it is not observable and provable, it is not real), we have turned the good and the beautiful into mere "social constructs" that have no validity on their own. While I am sympathetic in many ways with Dr. McBrayer's objections, I think he falls into the trap of discounting the Good and The Beautiful as valid in and of themselves, and tries, instead, to find ways to give them validity through the True. I think his argument would have been stronger had he used the language of validity rather than the language of truth. Goodness, Truth and Beauty each have their own validity, though interdependent and inseparable. When we artificially extract one of these and give it primacy, we distort reality and alienate ourselves from it.
  • Professor McBrayer seems to miss the major point of the Common Core concern: can students distinguish between premises based on (reasonably construed) fact and premises based on emotion when evaluating conclusions? I would prefer that students learn to reason rather than be taught moral 'truth' that follows Professor McBrayer's logic.
  • Moral issues cannot scientifically be treated on the level that Prof. McBrayer is attempting to use in this column: true or false, fact or opinion or both. Instead, they should be treated as important characteristics of the systematic working of a society or of a group of people in general. One can compare the working of two groups of people: one in which e.g. cheating and lying is acceptable, and one in which they are not. One can use historical or model examples to show the consequences and the working of specific systems of morals. I think that this method - suitably adjusted - can be used even in second grade.
  • Relativism has nothing to do with liberalism. The second point is that I'm not sure it does all that much harm, because I have yet to encounter a student who thought that he or she had to withhold judgment on those who hold opposing political views!

  • The conflation of faith as “unevidenced belief” with faith as “justified confidence” is simply a word trick used to buttress religion.
  • The constant scrutiny of our peers ensures that science is largely self-correcting, so that we really can approach the truth about our universe
  • There is strong evidence for the Higgs boson, whose existence was confirmed last year by two independent teams using a giant accelerator and rigorous statistical analysis. But there isn’t, and never will be, any evidence for that sea of milk.
  • Two objects of scientific faith are said to be physical laws and reason. Doing science, it is said, requires unevidenced faith in the “orderliness of nature” and an “unexplained set of physical laws,” as well as in the value of reason in determining truth. Both claims are wrong.
  • The orderliness of nature—the set of so-called natural laws—is not an assumption but an observation
  • We take nature as we find it, and sometimes it behaves predictably.
  • Reason—the habit of being critical, logical, and of learning from experience—is not an a priori assumption but a tool that’s been shown to work
  • Finally, isn’t science at least based on the faith that it’s good to know the truth? Hardly.
  • So the next time you hear someone described as a “person of faith,” remember that although it’s meant as praise, it’s really an insult.
