She became a science journalist. At first it was a lark, a way to get free press passes to conferences where she and her father could ask questions of the greatest minds in quantum mechanics, string theory and cosmology. But within a short time, as she started getting assignments, journalism became a calling, and an identity.

Tracking down the meaning of nothing — and, by extension, secrets about the origin of the universe and whether observer-independent reality exists — became the defining project of their lives. They spent hours together working on the puzzle, two dark heads bent over their physics books far into the night.

she has an epiphany — that for something to be real, it must be invariant — she flies home to share it with her father. They discuss her insight over breakfast at a neighborhood haunt, where they make a list on what they will affectionately call “the IHOP napkin.” They list all the possible “ingredients of ultimate reality,” planning to test each item for whether it is “real,” that is whether it is invariant and can exist in the absence of an observer.

their readings and interviews reveal that each item in turn is observer-dependent. Space? Observer-dependent, and therefore not real. Gravity, electromagnetism, angular momentum? No, no, and no. In the end, every putative “ingredient of ultimate reality” is eliminated, including one they hadn’t even bothered to put on the list because it seemed weird to: reality itself

What remained was an unsettling and essential insight: that “physics isn’t the machinery behind the workings of the world; physics is the machinery behind the illusion that there is a world.”

In the proposal, she clarifies how cosmology and quantum mechanics have evolved as scientists come to grips with the fact that things they had taken to be real — quantum particles, space-time, gravity, dimension — turn out to be ­observer-dependent.

As strange as it seems, being happier than average does not mean that one can’t also be unhappier than average.

In 2009, researchers from the University of Rochester conducted a study tracking the success of 147 recent graduates in reaching their stated goals after graduation. Some had “intrinsic” goals, such as deep, enduring relationships. Others had “extrinsic” goals, such as achieving reputation or fame. The scholars found that intrinsic goals were associated with happier lives. But the people who pursued extrinsic goals experienced more negative emotions, such as shame and fear. They even suffered more physical maladies.

the paradox of fame. Just like drugs and alcohol, once you become addicted, you can’t live without it. But you can’t live with it, either.

That impulse to fame by everyday people has generated some astonishing innovations.

Today, each of us can build a personal little fan base, thanks to Facebook, YouTube, Twitter and the like. We can broadcast the details of our lives to friends and strangers in an astonishingly efficient way. That’s good for staying in touch with friends, but it also puts a minor form of fame-seeking within each person’s reach. And several studies show that it can make us unhappy.

It makes sense. What do you post to Facebook? Pictures of yourself yelling at your kids, or having a hard time at work? No, you post smiling photos of a hiking trip with friends. You build a fake life — or at least an incomplete one — and share it. Furthermore, you consume almost exclusively the fake lives of your social media “friends.” Unless you are extraordinarily self-aware, how could it not make you feel worse to spend part of your time pretending to be happier than you are, and the other part of your time seeing how much happier others seem to be than you?Continue reading the main story

the bulk of the studies point toward the same important conclusion: People who rate materialistic goals like wealth as top personal priorities are significantly likelier to be more anxious, more depressed and more frequent drug users, and even to have more physical ailments than those who set their sights on more intrinsic values.

as the Dalai Lama pithily suggests, it is better to want what you have than to have what you want.

In 2004, two economists looked into whether more sexual variety led to greater well-being. They looked at data from about 16,000 adult Americans who were asked confidentially how many sex partners they had had in the preceding year, and about their happiness. Across men and women alike, the data show that the optimal number of partners is one.

This might seem totally counterintuitive. After all, we are unambiguously driven to accumulate material goods, to seek fame, to look for pleasure. How can it be that these very things can give us unhappiness instead of happiness? There are two explanations, one biological and the other philosophical.

From an evolutionary perspective, it makes sense that we are wired to seek fame, wealth and sexual variety. These things make us more likely to pass on our DNA.

here’s where the evolutionary cables have crossed: We assume that things we are attracted to will relieve our suffering and raise our happiness.

that is Mother Nature’s cruel hoax. She doesn’t really care either way whether you are unhappy — she just wants you to want to pass on your genetic material. If you conflate intergenerational survival with well-being, that’s your problem, not nature’s.

More philosophically, the problem stems from dissatisfaction — the sense that nothing has full flavor, and we want more. We can’t quite pin down what it is that we seek. Without a great deal of reflection and spiritual hard work, the likely candidates seem to be material things, physical pleasures or favor among friends and strangers.

We look for these things to fill an inner emptiness. They may bring a brief satisfaction, but it never lasts, and it is never enough. And so we crave more.

This search for fame, the lust for material things and the objectification of others — that is, the cycle of grasping and craving — follows a formula that is elegant, simple and deadly:Love things, use people.

This was Abd al-Rahman’s formula as he sleepwalked through life. It is the worldly snake oil peddled by the culture makers from Hollywood to Madison Avenue.

Simply invert the deadly formula and render it virtuous:Love people, use things.

It requires the courage to repudiate pride and the strength to love others — family, friends, colleagues, acquaintances, God and even strangers and enemies. Only deny love to things that actually are objects. The practice that achieves this is charity. Few things are as liberating as giving away to others that which we hold dear.

This also requires a condemnation of materialism.

Finally, it requires a deep skepticism of our own basic desires. Of course you are driven to seek admiration, splendor and physical license.

Declaring war on these destructive impulses is not about asceticism or Puritanism. It is about being a prudent person who seeks to avoid unnecessary suffering.

The authors claim that philosophy abandoned its relationship to other disciplines by creating its own purified domain, accessible only to credentialed professionals. It is true that from roughly 1930 to 1950, some philosophers — logical empiricists, in particular — did speak of philosophy having its own exclusive subject matter. But since that subject matter was logical analysis aimed at unifying all of science, interdisciplinarity was front and center.

Philosophy also played a role in 20th-century physics, influencing the great physicists Albert Einstein, Niels Bohr and Werner Heisenberg. The philosophers Moritz Schlick and Hans Reichenbach reciprocated that interest by assimilating the new physics into their philosophies.

developed ideas relating logic to linguistic meaning that provided a framework for studying meaning in all human languages. Others, including Paul Grice and J.L. Austin, explained how linguistic meaning mixes with contextual information to enrich communicative contents and how certain linguistic performances change social facts. Today a new philosophical conception of the relationship between meaning and cognition adds a further dimension to linguistic science.

Decision theory — the science of rational norms governing action, belief and decision under uncertainty — was developed by the 20th-century philosophers Frank Ramsey, Rudolph Carnap, Richard Jeffrey and others. It plays a foundational role in political science and economics by telling us what rationality requires, given our evidence, priorities and the strength of our beliefs. Today, no area of philosophy is more successful in attracting top young minds.

Philosophy also assisted psychology in its long march away from narrow behaviorism and speculative Freudianism. The mid-20th-century functionalist perspective pioneered by Hilary Putnam was particularly important. According to it, pain, pleasure and belief are neither behavioral dispositions nor bare neurological states. They are interacting internal causes, capable of very different physical realizations, that serve the goals of individuals in specific ways. This view is now embedded in cognitive psychology and neuroscience.

philosopher-mathematicians Gottlob Frege, Bertrand Russell, Kurt Gödel, Alonzo Church and Alan Turing invented symbolic logic, helped establish the set-theoretic foundations of mathematics, and gave us the formal theory of computation that ushered in the digital age

Philosophy of biology is following a similar path. Today’s philosophy of science is less accessible than Aristotle’s natural philosophy chiefly because it systematizes a larger, more technically sophisticated body of knowledge.

Philosophy’s interaction with mathematics, linguistics, economics, political science, psychology and physics requires specialization. Far from fostering isolation, this specialization makes communication and cooperation among disciplines possible. This has always been so.

Nor did scientific progress rob philosophy of its former scientific subject matter, leaving it to concentrate on the broadly moral. In fact, philosophy thrives when enough is known to make progress conceivable, but it remains unachieved because of methodological confusion. Philosophy helps break the impasse by articulating new questions, posing possible solutions and forging new conceptual tools.

Our knowledge of the universe and ourselves expands like a ripple surrounding a pebble dropped in a pool. As we move away from the center of the spreading circle, its area, representing our secure knowledge, grows. But so does its circumference, representing the border where knowledge blurs into uncertainty and speculation, and methodological confusion returns. Philosophy patrols the border, trying to understand how we got there and to conceptualize our next move.  Its job is unending.

Although progress in ethics, political philosophy and the illumination of life’s meaning has been less impressive than advances in some other areas, it is accelerating.

the advances in our understanding because of careful formulation and critical evaluation of theories of goodness, rightness, justice and human flourishing by philosophers since 1970 compare well to the advances made by philosophers from Aristotle to 1970

The knowledge required to maintain philosophy’s continuing task, including its vital connection to other disciplines, is too vast to be held in one mind. Despite the often-repeated idea that philosophy’s true calling can only be fulfilled in the public square, philosophers actually function best in universities, where they acquire and share knowledge with their colleagues in other disciplines. It is also vital for philosophers to engage students — both those who major in the subject, and those who do not. Although philosophy has never had a mass audience, it remains remarkably accessible to the average student; unlike the natural sciences, its frontiers can be reached in a few undergraduate courses.

The Higgs boson was the last missing piece of the Standard Model, which explains all we know about subatomic particles and forces. But there are questions this model does not answer, such as what happens at the bottom of a black hole, the identity of the dark matter and dark energy that rule the cosmos, or why the universe is matter and not antimatter.

When physicists announced in 2012 that they had indeed discovered the Higgs boson, it was not the end of physics. It was not even, to paraphrase Winston Churchill, the beginning of the end.

A coincidence is the most probable explanation for the surprising bumps in data from the collider, physicists from the experiments cautioned, saying that a lot more data was needed and would in fact soon be available

The Large Hadron Collider was built at a cost of some $10 billion, to speed protons around an 18-mile underground track at more than 99 percent of the speed of light and smash them together in search of new particles and forces of nature. By virtue of Einstein’s equivalence of mass and energy, the more energy poured into these collisions, the more massive particles can come out of them. And by the logic of quantum microscopy, the more energy they have to spend, the smaller and more intimate details of nature physicists can see.

Since June, after a two-year shutdown, CERN physicists have been running their collider at nearly twice the energy with which they discovered the Higgs, firing twin beams of protons with 6.5 trillion electron volts of energy at each other in search of new particles to help point them to deeper laws.

The most intriguing result so far, reported on Tuesday, is an excess of pairs of gamma rays corresponding to an energy of about 750 billion electron volts. The gamma rays, the physicists said, could be produced by the radioactive decay of a new particle, in this case perhaps a cousin of the Higgs boson, which itself was first noticed because it decayed into an abundance of gamma rays.

Or it could be a more massive particle that has decayed in steps down to a pair of photons. Nobody knows. No model predicted this, which is how some scientists like it.

“We are barely coming to terms with the power and the glory” of the CERN collider’s ability to operate at 13 trillion electron volts, Dr. Spiropulu said in a text message. “We are now entering the era of taking a shot in the dark!”

Upon getting bumped on the head by a falling apple, Newton airily dreams up the laws of gravity and the rest, as they say, is history

When the black plague closed Cambridge University, where he was a student, for two years starting in 1665, he spent the long months locked up at home studying complex mathematics, physics and optics.

It was during this fruitful time that Newton, with the help of a crystal prism, became the first to discover that white light is made up a spectrum of colors

He also developed the concept of infinite-series calculus, the kind of scary math studied today by engineering and statistics scholars.

By 1666, Newton had even laid the blueprints for his three laws of motion, still recited by physics students everywhere:An object will remain in a state of inertia unless acted upon by force.The relationship between acceleration and applied force is F=ma.For every action there is an equal and opposite reaction.

Across the pages of the Principia, Newton breaks down the workings of the solar system into "'simple"' equations, explaining away the nature of planetary orbits and the pull between heavenly bodies.

Not only that, but the universe appears to be governed by a kind of cosmic censorship: Regions of extreme gravity—where space-time curves so sharply that Einstein’s equations malfunction and the true, quantum nature of gravity and space-time must be revealed—always hide behind the horizons of black holes.

Dyson, who helped develop quantum electrodynamics (the theory of interactions between matter and light) and is professor emeritus at the Institute for Advanced Study in Princeton, New Jersey, where he overlapped with Einstein, disagrees with the argument that quantum gravity is needed to describe the unreachable interiors of black holes. And he wonders whether detecting the hypothetical graviton might be impossible, even in principle. In that case, he argues, quantum gravity is metaphysical, rather than physics.

The ability to detect the “grin” of quantum gravity would seem to refute Dyson’s argument. It would also kill the gravitational decoherence theory, by showing that gravity and space-time do maintain quantum superpositions.

If gravity is a quantum interaction, then the answer is: It depends. Each component of the blue diamond’s superposition will experience a stronger or weaker gravitational attraction to the red diamond, depending on whether the latter is in the branch of its superposition that’s closer or farther away. And the gravity felt by each component of the red diamond’s superposition similarly depends on where the blue diamond is.

“When did it become taboo in this country to talk about getting healthy?” my friend Bill Maher asked in a recent monologue. “Fat shaming doesn’t need to end; it needs to make a comeback. Some amount of shame is good. We shamed people out of smoking and into wearing seat belts. We shamed them out of littering and most of them out of racism.”

On one side are helpless victims, who react to any debate with cries of oppression, and take no responsibility for their own physical destiny; on the other are brutal realists, with a callous touch, often refusing to see the genetic, social, and psychological complexity of fatness, or that serious health issues are not universal among heavier types

the two stances reflect our two ideological poles — not so much left and right anymore as nurture and nature. One pole argues nature doesn’t independently exist and everything is social; and one blithely asserts that nature determines everything. Both are ruinous attempts to bludgeon uncomfortable reality into satisfying ideology.

is to grapple with complexity in a way that can be rigorously empirical and yet also humane.

We are all driven by instinctive attraction, but men are particularly subject to fixed and crude notions of hotness. Beauty will thereby always be the source of extraordinary and extraordinarily unfair advantage, even if it captures only a tiny slice of what being human is about.

This is our reality. We are neither angels nor beasts, but we partake of both. We can rarely make the ugly beautiful, and if we do, it’s a moral achievement. However much we try, we will never correct the core natural inequalities and differences of our mammalian existence. But we can hazard a moral middle, seeing beauty in many ways, acknowledging the humanity of all shapes and sizes, while managing our health and weight in ways that are not totally subject to the gaze of others.

What we needed, in some ways, for our collective mental health, was a catalyst for greater physical socialization, more human contact, and more meaningful community. What we’re getting, I fear, is the opposite

For Beck, moving past purity involves less emphasis "on the physical act of sex and how that physical act is 'defiling' and more upon issues related to covenant faithfulness, care, and harm. ... God's interest in sex, then, is less puritanical than a concern about how we hurt and damage each other, physically and emotionally, in ways that often leave lifelong scars."

Although each of these post-purity perspectives diverges from the current evangelical narrative to varying degrees, the common thread among them seems to be a desire for a more holistic sexual ethic, one that remains thoroughly Christian while shifting away from the metaphor of purity to concepts of sexual health and wholeness

Hedonic well-being comes from an experience a person seeks out that gives them pleasure.

Eudaimonic well-being is a kind of happiness that comes not from consuming something but from a sustained effort at working toward something bigger than you.

they can and do influence each other, so it has been hard for scientists to measure which kind has had a greater positive influence on someone's physical or psychological well-being.

there is an increased expression of genes involved in inflammation and a decreased antiviral response. People who are subjected to long periods of stress have white blood cells that make slightly more pro-inflammatory proteins on a constant basis.

Bottom line? Happiness that comes from working for the greater good has a much more positive genetic impact.

The people who found happiness by pursuing a greater good had a lower level of this inflammatory gene expression and strong antiviral and antibody gene expression.

For those of us seeking to appear friendly and trustworthy to others, a new study underscores an old, chipper piece of advice: Put on a happy face.

the relevance of facial expressions to perceptions of characteristics such as trustworthiness and friendliness.

for those faces lacking structural cues, people could no longer perceive strength but could still perceive personality traits based on facial expressions.

An analysis revealed that participants generally ranked people with a happy expression as friendly and trustworthy but not those with angry expressions.

rank faces as indicative of physical strength based on facial expression but graded faces that were very broad as that of a strong individual.

In the first variation, for faces lacking emotional cues, people could no longer perceive personality traits but could still perceive strength based on width

perceptions of abilities such as physical strength are not dependent on facial expressions but rather on facial bone structure.

As might be expected, participants picked faces with happier expressions as financial advisors and selected broader faces as belonging to power-lifting champs.

Most of the participants found the computer-generated averages to be good representations of trustworthiness or strength — and generally saw the average “financial advisor” face as more trustworthy and the “power-lifter” face as stronger.

he findings suggest facial expressions strongly influence perception of traits such as trustworthiness, friendliness or warmth, but not ability (strength, in these experiments).

facial structure influences the perception of physical ability but not intentions (such as friendliness and trustworthiness, in this instance)

this new work reveals how perceptions of the same person can vary greatly depending on that person’s facial expression in any given moment

The findings above come with a big caveat: Only male faces were shown to subjects.

Studies of facial width and height in females have shown mixed results, so presenting study subjects with a mix of male and female faces would have yielded inconclusive results.

In our everyday lives this study and others make clear that although we might try to influence others’ perceptions of us with photos showing us donning sharp attire or displaying a self-assured attitude, the most important determinant of others' perception of and consequent behavior toward us is our faces.

But both moms and dads directed their sons to face their fears, with instruction on how to complete the task on their own.

Misadventures meant that I should try again. With each triumph over fear and physical adversity, I gained confidence.

She said that her own mother had been very fearful, gasping at anything remotely rough-and-tumble. “I had been so discouraged from having adventures, and I wanted you to have a more exciting childhood,”

arents are “four times more likely to tell girls than boys to be more careful”

“Girls may be less likely than boys to try challenging physical activities, which are important for developing new skills.” This study points to an uncomfortable truth: We think our daughters are more fragile, both physically and emotionally, than our sons.

Nobody is saying that injuries are good, or that girls should be reckless. But risk taking is important

It follows that by cautioning girls away from these experiences, we are not protecting them. We are failing to prepare them for life.

When a girl learns that the chance of skinning her knee is an acceptable reason not to attempt the fire pole, she learns to avoid activities outside her comfort zone.

Fear becomes a go-to feminine trait, something girls are expected to feel and express at will.

By the time a girl reaches her tweens no one bats an eye when she screams at the sight of an insect.

When girls become women, this fear manifests as deference and timid decision making

We must chuck the insidious language of fear (Be careful! That’s too scary!) and instead use the same terms we offer boys, of bravery and resilience. We need to embolden girls to master skills that at first appear difficult, even dangerous. And it’s not cute when a 10-year-old girl screeches, “I’m too scared.”

I was often scared. Of course I was. So were the men.

The iron law of Darwinian evolution is that everything that exists strives with all its power to reproduce, to extend life into the future, and that every feature of every creature can be explained as an adaptation toward this end. For the artist to deny any connection with the enterprise of life, then, is to assert his freedom from this universal imperative; to reclaim negatively the autonomy that evolution seems to deny to human beings. It is only because we can freely choose our own ends that we can decide not to live for life, but for some other value that we posit. The artist’s decision to produce spiritual offspring rather than physical ones is thus allied to the monk’s celibacy and the warrior’s death for his country, as gestures that deny the empire of mere life.

Animals produce beauty on their bodies; humans can also produce it in their artifacts. The natural inference, then, would be that art is a human form of sexual display, a way for males to impress females with spectacularly redundant creations.

For Darwin, the human sense of beauty was not different in kind from the bird’s.

Still, Darwin recognized that the human sense of beauty was mediated by “complex ideas and trains of thought,” which make it impossible to explain in terms as straightforward as a bird’s:

Put more positively, one might say that any given work of art can be discussed critically and historically, but not deduced from the laws of evolution.

with the rise of evolutionary psychology, it was only a matter of time before the attempt was made to explain art in Darwinian terms. After all, if ethics and politics can be explained by game theory and reciprocal altruism, there is no reason why aesthetics should be different: in each case, what appears to be a realm of human autonomy can be reduced to the covert expression of biological imperatives

Still, there is an unmistakable sense in discussions of Darwinian aesthetics that by linking art to fitness, we can secure it against charges of irrelevance or frivolousness—that mattering to reproduction is what makes art, or anything, really matter.

The first popular effort in this direction was the late Denis Dutton’s much-discussed book The Art Instinct, which appeared in 2009.

Dutton’s Darwinism was aesthetically conservative: “Darwinian aesthetics,” he wrote, “can restore the vital place of beauty, skill, and pleasure as high artistic values.” Dutton’s argument has recently been reiterated and refined by a number of new books,

“The universality of art and artistic behaviors, their spontaneous appearance everywhere across the globe ... and the fact that in most cases they can be easily recognized as artistic across cultures suggest that they derive from a natural, innate source: a universal human psychology.”

Again like language, art is universal in the sense that any local expression of it can be “learned” by anyone.

Yet earlier theorists of evolution were reluctant to say that art was an evolutionary adaptation like language, for the simple reason that it does not appear to be evolutionarily adaptive.

Stephen Jay Gould suggested that art was not an evolutionary adaptation but what he called a “spandrel”—that is, a showy but accidental by-product of other adaptations that were truly functiona

the very words “success” and “failure,” despite themselves, bring an emotive and ethical dimension into the discussion, so impossible is it for human beings to inhabit a valueless world. In the nineteenth century, the idea that fitness for survival was a positive good motivated social Darwinism and eugenics. Proponents of these ideas thought that in some way they were serving progress by promoting the flourishing of the human race, when the basic premise of Darwinism is that there is no such thing as progress or regress, only differential rates of reproduction

In particular, Darwin suggests that it is impossible to explain the history or the conventions of any art by the general imperatives of evolution

Boyd begins with the premise that human beings are pattern-seeking animals: both our physical perceptions and our social interactions are determined by our brain’s innate need to find and to

Art, then, can be defined as the calisthenics of pattern-finding. “Just as animal physical play refines performance, flexibility, and efficiency in key behaviors,” Boyd writes, “so human art refines our performance in our key perceptual and cognitive modes, in sight (the visual arts), sound (music), and social cognition (story). These three modes of art, I propose, are adaptations ... they show evidence of special design in humans, design that offers survival and especially reproductive advantages.”

make coherent patterns

Because of this disconnect between perception and reality, visual illusions demonstrate the ways in which the brain can fail to re-create the physical world.

There is a genuine psychological reality behind the idea of free will. The debate is merely about whether this reality deserves to be called free will.

Our actions cannot break the laws of physics, but they can be influenced by things beyond gravity, friction, and electromagnetic charges. No number of facts about a carbon atom can explain life, let alone the meaning of your life. These causes operate at different levels of organization.

Free will cannot violate the laws of physics or even neuroscience, but it invokes causes that go beyond them

Self-control furnishes the possibility of acting from rational principles rather than acting on impulse.

If you think of freedom as being able to do whatever you want, with no rules, you might be surprised to hear that free will is for following rules. Doing whatever you want is fully within the capability of any animal in the forest. Free will is for a far more advanced way of acting

That, in a nutshell, is the inner deciding process that humans have evolved. That is the reality behind the idea of free will: these processes of rational choice and self-control

Self-control counts as a kind of freedom because it begins with not acting on every impulse. The simple brain acts whenever something triggers a response: A hungry creature sees food and eats it

Our ancestors evolved the ability to act in the ways necessary for culture to succeed. Free will likely will be found right there—it’s what enables humans to control their actions in precisely the ways required to build and operate complex social systems.

Understanding free will in this way allows us to reconcile the popular understanding of free will as making choices with our scientific understanding of the world.

people routinely enjoy intellectually invigorating activities without suffering mental exhaustion.

Such fatigue seems much more likely to follow sustained mental effort that we do not seek for pleasure—such as the obligatory SAT—especially when we expect that the ordeal will drain our brains. If we think an exam or puzzle will be difficult, it often will be.

Studies have shown that something similar happens when people exercise and play sports: a large component of physical exhaustion is in our heads. In related research, volunteers that cycled on an exercise bike following a 90-minute computerized test of sustained attention quit pedaling from exhaustion sooner than participants that watched emotionally neutral documentaries before exercising

In the specific case of the SAT, something beyond pure mental effort likely contributes to post-exam stupor: stress. After all, the brain does not function in a vacuum. Other organs burn up energy, too. Taking an exam that partially determines where one will spend the next four years is nerve-racking enough to send stress hormones swimming through the blood stream, induce sweating, quicken heart rates and encourage fidgeting and contorted body postures. The SAT and similar trials are not just mentally taxing—they are physically exhausting, too.
