How many moments each day do you spend in total silence?

Silence relieves stress and tension.

noise pollution has been found to lead to high blood pressure and heart attacks, as well as impairing hearing and overall health. Loud noises raise stress levels by activating the brain’s amygdala and causing the release of the stress hormone cortisol

In our everyday lives, sensory input is being thrown at us from every angle. When we can finally get away from these sonic disruptions, our brains’ attention centers have the opportunity to restore themselves.

The ceaseless attentional demands of modern life put a significant burden on the prefrontal cortex of the brain, which is involved in high-order thinking, decision-making and problem-solving.

Silence can quite literally grow the brain.

Sleep deprivation has consequences for cognitive function, namely for attention and memory, two of the most crucial functions for any medical student.

If drinking alcohol before an exam is ludicrous, shouldn't an all-nighter be too?

The Institute of Medicine estimates that 50 to 70 million U.S. adults have a sleep or wakefulness disorder

If we do not find ways to make time for sleep now, we will face greater difficulty in finding balance when the hours become more demanding in our clinical years, in residency, and beyond.

"our ability to address and solve the problems we're facing as individuals and as a society.

"If sleep does not serve an absolutely vital function, then it is the biggest mistake the evolutionary process ever made."

During adolescence, the neurocircuitry strengthens and allows for multitasking, enhanced ability to solve problems, and the capability to process complex information. Furthermore, adolescent brain plasticity provides an opportunity to develop talents and lifelong interests; however, neurotoxic insult, trauma, chronic stress, drug abuse, and sedentary lifestyles may have a negative impact during this sensitive period of brain maturation

Experiments with adolescent boys found that they enjoyed a horror film more when their female companion (who was a research plant) was visibly scared.

Where there is no imagination – there is no horror

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.

It also offers its experts' predictions about what the most-desired life skills (for young people, but ostensibly for everyone else, too) will be in the year 2020. Among the skills they highlighted: public problem-solving through cooperative work -- crowdsourcing and the like; the ability to search effectively for information online; the ability to distinguish the quality and veracity of online discoveries; the ability to synthesize, or combine facts and details from different sources into coherent narratives; the ability to concentrate; and the ability to distinguish between the signal and the noise as the information we're exposed to gets bigger, and broader, and more plentiful.

All these skills can be taught. The question is whether kids will learn them in school, or outside of it.

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.

Unlike previous video lectures, which offered a “static” learning model, the Coursera system breaks lectures into segments as short as 10 minutes and offers quick online quizzes as part of each segment.

Where essays are required, especially in the humanities and social sciences, the system relies on the students themselves to grade their fellow students’ work, in effect turning them into teaching assistants.

The Coursera system also offers an online feature that allows students to get support from a global student community. Dr. Ng said an early test of the system found that questions were typically answered within 22 minutes.

Dr. Koller said the educational approach was similar to that of the “flipped classroom,” pioneered by the Khan Academy, a creation of the educator Salman Khan. Students watch lectures at home and then work on problem-solving or “homework” in the classroom, either one-on-one with the teacher or in small groups.

We want to customize our lives. We want to move in and out of where we are because the thing we value most is control over where we focus our attention. We have gotten used to the idea of being in a tribe of one, loyal to our own party.

We are tempted to think that our little “sips” of online connection add up to a big gulp of real conversation. But they don’t.

“Someday, someday, but certainly not now, I’d like to learn how to have a conversation.”

We can’t get enough of one another if we can use technology to keep one another at distances we can control: not too close, not too far, just right. I think of it as a Goldilocks effect. Texting and e-mail and posting let us present the self we want to be. This means we can edit. And if we wish to, we can delete. Or retouch: the voice, the flesh, the face, the body. Not too much, not too little — just right.

Human relationships are rich; they’re messy and demanding. We have learned the habit of cleaning them up with technology.

I have often heard the sentiment “No one is listening to me.” I believe this feeling helps explain why it is so appealing to have a Facebook page or a Twitter feed — each provides so many automatic listeners. And it helps explain why — against all reason — so many of us are willing to talk to machines that seem to care about us. Researchers around the world are busy inventing sociable robots, designed to be companions to the elderly, to children, to all of us.

Connecting in sips may work for gathering discrete bits of information or for saying, “I am thinking about you.” Or even for saying, “I love you.” But connecting in sips doesn’t work as well when it comes to understanding and knowing one another. In conversation we tend to one another.

We can attend to tone and nuance. In conversation, we are called upon to see things from another’s point of view.

I’m the one who doesn’t want to be interrupted. I think I should. But I’d rather just do things on my BlackBerry.

And we use conversation with others to learn to converse with ourselves. So our flight from conversation can mean diminished chances to learn skills of self-reflection

we have little motivation to say something truly self-reflective. Self-reflection in conversation requires trust. It’s hard to do anything with 3,000 Facebook friends except connect.

we seem almost willing to dispense with people altogether. Serious people muse about the future of computer programs as psychiatrists. A high school sophomore confides to me that he wishes he could talk to an artificial intelligence program instead of his dad about dating; he says the A.I. would have so much more in its database. Indeed, many people tell me they hope that as Siri, the digital assistant on Apple’s iPhone, becomes more advanced, “she” will be more and more like a best friend — one who will listen when others won’t.

FACE-TO-FACE conversation unfolds slowly. It teaches patience. When we communicate on our digital devices, we learn different habits. As we ramp up the volume and velocity of online connections, we start to expect faster answers. To get these, we ask one another simpler questions; we dumb down our communications, even on the most important matters.

WE expect more from technology and less from one another and seem increasingly drawn to technologies that provide the illusion of companionship without the demands of relationship. Always-on/always-on-you devices provide three powerful fantasies: that we will always be heard; that we can put our attention wherever we want it to be; and that we never have to be alone. Indeed our new devices have turned being alone into a problem that can be solved.

When people are alone, even for a few moments, they fidget and reach for a device. Here connection works like a symptom, not a cure, and our constant, reflexive impulse to connect shapes a new way of being.

Think of it as “I share, therefore I am.” We use technology to define ourselves by sharing our thoughts and feelings as we’re having them. We used to think, “I have a feeling; I want to make a call.” Now our impulse is, “I want to have a feeling; I need to send a text.”

Lacking the capacity for solitude, we turn to other people but don’t experience them as they are. It is as though we use them, need them as spare parts to support our increasingly fragile selves.

If we are unable to be alone, we are far more likely to be lonely. If we don’t teach our children to be alone, they will know only how to be lonely.

I am a partisan for conversation. To make room for it, I see some first, deliberate steps. At home, we can create sacred spaces: the kitchen, the dining room. We can make our cars “device-free zones.”

What the rise of the BRICs symbolizes to both panicked individuals in the West and optimistic ones elsewhere is a radical shift in the geography of power -- a catch-up or reversal of the Western global dominance that was established with the Industrial Revolution.

developing countries won't be able to follow the West's path to becoming rich, because that path required certain things that were largely particular to that one period in history.

The challenge ahead for the BRICs, then, is to figure out how to maintain growth in a world where the vast new frontier opened up by the Industrial Revolution appears to be closing. The BRICs can play the West's game better than the West, both through technological innovation and population growth, but only for so long. The whole world has to figure out a way of dealing with energy and agriculture.

The key difference between bilinguals and monolinguals may be more basic: a heightened ability to monitor the environment. “Bilinguals have to switch languages quite often — you may talk to your father in one language and to your mother in another language,” says Albert Costa, a researcher at the University of Pompeu Fabra in Spain. “It requires keeping track of changes around you in the same way that we monitor our surroundings when driving.”

individuals with a higher degree of bilingualism — measured through a comparative evaluation of proficiency in each language — were more resistant than others to the onset of dementia and other symptoms of Alzheimer’s disease: the higher the degree of bilingualism, the later the age of onset.

Conservatives took the attitudes and behaviors Harrington saw as symptoms of poverty and portrayed them as its direct causes.

In his 1984 book, “Losing Ground,” Mr. Murray argued that welfare programs abet rather than ameliorate poverty. The book dismissed Harrington’s prescription for ending poverty, and Harrington returned the favor. In “The New American Poverty,” published the same year, he called Mr. Murray the right-wing equivalent of a “vulgar Marxist,” a social theorist who believed in a “one-to-one relationship between the economic and the political or the psychological.”

Harrington’s culture-of-poverty thesis was at best an ambiguous impediment to understanding — in later books, he made no use of the term. But in its moral clarity, “The Other America” was ultimately optimistic; it was less an indictment and more an appeal to Americans to live up to their better instincts.

I fear we’re facing a crisis in which a chunk of working-class America risks being calcified into an underclass, marked by drugs, despair, family decline, high incarceration rates and a diminishing role of jobs and education as escalators of upward mobility. We need a national conversation about these dimensions of poverty, and maybe Murray can help trigger it. I fear that liberals are too quick to think of inequality as basically about taxes. Yes, our tax system is a disgrace, but poverty is so much deeper and more complex than that.

to blame liberal social policies for the pathologies he examines. Yes, I’ve seen disability programs encourage some people to drop out of the labor force. But there were far greater forces at work, such as the decline in good union jobs.

Eighty percent of the people in my high school cohort dropped out or didn’t pursue college because it used to be possible to earn a solid living at the steel mill, the glove factory or sawmill. That’s what their parents had done. But the glove factory closed, working-class jobs collapsed and unskilled laborers found themselves competing with immigrants. There aren’t ideal solutions, but some evidence suggests that we need more social policy, not less. Early childhood education can support kids being raised by struggling single parents. Treating drug offenders is far cheaper than incarcerating them. A new study finds that a jobs program for newly released prison inmates left them 22 percent less likely to be convicted of another crime. This initiative, by the Center for Employment Opportunities, more than paid for itself: each $1 brought up to $3.85 in benefits.

By emphasizing a focus on the here and now, it trains the mind to stay on task and avoid distraction.

“Your ability to recognize what your mind is engaging with, and control that, is really a core strength,” said Peter Malinowski, a psychologist and neuroscientist at Liverpool John Moores University in England. “For some people who begin mindfulness training, it’s the first time in their life where they realize that a thought or emotion is not their only reality, that they have the ability to stay focused on something else, for instance their breathing, and let that emotion or thought just pass by.”

the higher adults scored on a measurement of mindfulness, the worse they performed on tests of implicit learning — the kind that underlies all sorts of acquired skills and habits but that occurs without conscious awareness.

he found that having participants spend a brief period of time on an undemanding task that maximizes mind wandering improved their subsequent performance on a test of creativity. In a follow-up study, he reported that physicists and writers alike came up with their most insightful ideas while spacing out.

The trick is knowing when mindfulness is called for and when it’s not.

one of the most surprising findings of recent mindfulness studies is that it could have unwanted side effects. Raising roadblocks to the mind’s peregrinations could, after all, prevent the very sort of mental vacations that lead to epiphanies.

“There’s so much our brain is doing when we’re not aware of it,” said the study’s leader, Chelsea Stillman, a doctoral candidate. “We know that being mindful is really good for a lot of explicit cognitive functions. But it might not be so useful when you want to form new habits.” Learning to ride a bicycle, speak grammatically or interpret the meaning of people’s facial expressions are three examples of knowledge we acquire through implicit learning

“Educational investment will not be attractive to those without unique skills,” she said. Graduates, she noted, need to earn a return on their investment in training: “But instead they will lose jobs, replaced by information simulation. They will stay uneducated.” In such a scenario, high-salary jobs would remain for those equipped with problem-solving skills, she predicted. But many common tasks now done by college graduates might vanish.

Over the next 10 to 20 years, “10 percent to 20 percent pushed out of work by A.I. will be a catastrophe,” she says. “I can’t begin to think what 50 percent would mean — way beyond a catastrophe and such numbers can’t be ruled out if A.I. performs well in the future.”

A recent study published by the Program on the Impacts of Future Technology, at Oxford University’s Oxford Martin School, predicted that nearly half of all jobs in the United States could be replaced by computers over the next two decades.

Smart machines will give companies “the opportunity to automate many tasks, redesign jobs, and do things never before possible even with the best human work forces,” according to a report this year by the business consulting firm McKinsey.

Advances in speech recognition, translation and pattern recognition threaten employment in the service sectors — call centers, marketing and sales — precisely the sectors that provide most jobs in developed economies.

Gartner’s 2013 chief executive survey, published in April, found that 60 percent of executives surveyed dismissed as “‘futurist fantasy” the possibility that smart machines could displace many white-collar employees within 15 years.

Kenneth Brant, research director at Gartner, told a conference in October: “Job destruction will happen at a faster pace, with machine-driven job elimination overwhelming the market’s ability to create valuable new ones.”

Optimists say this could lead to the ultimate elimination of work — an “Athens without the slaves” — and a possible boom for less vocational-style education. Mr. Brant’s hope is that such disruption might lead to a system where individuals are paid a citizen stipend and be free for education and self-realization. “This optimistic scenario I call Homo Ludens, or ‘Man, the Player,’ because maybe we will not be the smartest thing on the planet after all,” he said. “Maybe our destiny is to create the smartest thing on the planet and use it to follow a course of self-actualization.”

The results were similarly disturbing when students were tested to determine understanding of basic concepts. More instruction wasn't helping students advance from novice to expert. In fact, the data indicated the opposite: students had more novice-like beliefs after they completed a course than they had when they started.

But in addition, experts have a mental organizational structure that facilitates the retrieval and effective application of their knowledge.

experts have an ability to monitor their own thinking ("metacognition"), at least in their discipline of expertise. They are able to ask themselves, "Do I understand this? How can I check my understanding?"

But that is not what cognitive science tells us. It tells us instead that students need to develop these different ways of thinking by means of extended, focused mental effort.

new ways of thinking are always built on the prior thinking of the individual, so if the educational process is to be successful, it is essential to take that prior thinking into account.

Given that lectures were devised as a means of transferring knowledge from one to many, it seems obvious that we would ensure that people retain the information they are consuming.

What is elementary, worldly wisdom? Well, the first rule is that you can't really know anything if you just remember isolated facts and try and bang 'em back. If the facts don't hang together on a latticework of theory, you don't have them in a usable form.

"So it makes perfect sense," Wieman writes, "that they are not learning to think like experts, even though they are passing science courses by memorizing facts and problem-solving recipes."

Anything one can do to reduce cognitive load improves learning.

A second way teachers can improve instruction is by recognizing the importance of student beliefs about science

My third example of how teaching and learning can be improved is by implementing the principle that effective teaching consists of engaging students, monitoring their thinking, and providing feedback.

I assign students to groups the first day of class (typically three to four students in adjacent seats) and design each lecture around a series of seven to 10 clicker questions that cover the key learning goals for that day.

The process of critiquing each other's ideas in order to arrive at a consensus also enormously improves both their ability to carry on scientific discourse and to test their own understanding. [Change]

This is one of the most important reasons to keep a diary: it can make you more aware of your own progress, thus becoming a wellspring of joy in your workday.

We can’t, however, simply will ourselves into better habits. Since willpower is a limited resource, whenever we’ve overexerted our self-discipline in one domain, a concept known as “ego depletion” kicks in and renders us mindless automata in another

the key to changing a habit is to invest heavily in the early stages of habit-formation so that the behavior becomes automated and we later default into it rather than exhausting our willpower wrestling with it. Young also cautions that it’s a self-defeating strategy to try changing several habits at once. Rather, he advises, spend one month on each habit alone before moving on to the next

a diary boosts your creativity

the primary benefit of a diary as a purely pragmatic record of your workday productivity and progress — while most dedicated diarists would counter that the core benefits are spiritual and psychoemotional — it does offer some valuable insight into the psychology of how journaling elevates our experience of everyday life:

what you do every day is best seen as an iceberg, with a small fraction of conscious decision sitting atop a much larger foundation of habits and behaviors.

the authors point to a pattern that reveals the single most important motivator: palpable progress on meaningful work: On the days when these professionals saw themselves moving forward on something they cared about — even if the progress was a seemingly incremental “small win” — they were more likely to be happy and deeply engaged in their work. And, being happier and more deeply engaged, they were more likely to come up with new ideas and solve problems creatively.

Although the act of reflecting and writing, in itself, can be beneficial, you’ll multiply the power of your diary if you review it regularly — if you listen to what your life has been telling you. Periodically, maybe once a month, set aside time to get comfortable and read back through your entries. And, on New Year’s Day, make an annual ritual of reading through the previous year.

This, they suggest, can yield profound insights into the inner workings of your own mind — especially if you look for specific clues and patterns, trying to identify the richest sources of meaning in your work and the types of projects that truly make your heart sing. Once you understand what motivates you most powerfully, you’ll be able to prioritize this type of work in going forward. Just as important, however, is cultivating a gratitude practice and acknowledging your own accomplishments in the diary:

Fields argues that if we move along the Uncertainty Curve either too fast or too slowly, we risk either robbing the project of its creative potential and ending up in mediocrity. Instead, becoming mindful of the psychology of that process allows us to pace ourselves better and master that vital osmosis between freedom and constraint.

Schwalbe reminds us of the “impact bias” — our tendency to greatly overestimate the intensity and extent of our emotional reactions, which causes us to expect failures to be more painful than they actually are and thus to fear them more than we should.

When we think about taking a risk, we rarely consider how good we will be at reframing a disappointing outcome. In short, we underestimate our resilience.

The second reason is focalism. When we contemplate failure from afar, according to Gilbert and Wilson, we tend to overemphasize the focal event (i.e., failure) and overlook all the other episodic details of daily life that help us move on and feel better. The threat of failure is so vivid that it consumes our attention

don’t let yourself forget that the good life, the meaningful life, the truly fulfilling life, is the life of presence, not of productivity.

there is a risk that a radical capitalistic ideology could spread which refuses even to consider these problems, in the a priori belief that any attempt to solve them is doomed to failure and which blindly entrusts their solution to the free development of market forces.

Could anyone have offered a more potent critique of current Republican ideology than John Paul II? Could anything better illustrate John Paul II’s critique of radical capitalist ideology than the GOP’s refusal to be concerned in any way about a fundamental question like access to basic healthcare for millions of citizens in the richest country on earth?

And in the Church of Limbaugh, market capitalism is an unqualified, eternal good. It is the ever-lasting truth about human beings. It is inextricable from any concept of human freedom. The fewer restrictions on it, the better.

the Pope is not making an empirical observation. In so far as he is, he agrees with you. What he’s saying is that this passion for material things is not what makes us good or happy. That’s all

if the mania for more and more materialist thrills distracts us from, say, the plight of a working American facing bankruptcy because of cancer, or the child of an illegal immigrant with no secure home, then it is a deeply immoral distraction.

material goods are not self-evidently the purpose of life and are usually (and in Jesus’ stern teachings always) paths away from God and our own good and our own happiness.

Christianity is one of the most powerful critiques of radical market triumphalism.
