"BBC Horizon 1993 Richard Feynman - No Ordinary Genius "

""If it disagrees with experiment, it is wrong." Richard Feynman - Nobel-winning physics icon, curiosity champion, graphic novel hero, bongo drummer, wager-maker, no ordinary genius - would have been 94 today. To celebrate, here is one of Feynman's most beloved classics, a 1964 lecture in which he distills with equal parts wit and wisdom the essence of the scientific method:"

"n September 18, 2007, a few dozen neuroscientists, psychiatrists, and drug-company executives gathered in a hotel conference room in Brussels to hear some startling news. It had to do with a class of drugs known as atypical or second-generation antipsychotics, which came on the market in the early nineties. The drugs, sold under brand names such as Abilify, Seroquel, and Zyprexa, had been tested on schizophrenics in several large clinical trials, all of which had demonstrated a dramatic decrease in the subjects' psychiatric symptoms. As a result, second-generation antipsychotics had become one of the fastest-growing and most profitable pharmaceutical classes. By 2001, Eli Lilly's Zyprexa was generating more revenue than Prozac. It remains the company's top-selling drug. But the data presented at the Brussels meeting made it clear that something strange was happening: the therapeutic power of the drugs appeared to be steadily waning. A recent study showed an effect that was less than half of that documented in the first trials, in the early nineteen-nineties. Many researchers began to argue that the expensive pharmaceuticals weren't any better than first-generation antipsychotics, which have been in use since the fifties. "In fact, sometimes they now look even worse," John Davis, a professor of psychiatry at the University of Illinois at Chicago, told me. "

"SPEAKING two languages rather than just one has obvious practical benefits in an increasingly globalized world. But in recent years, scientists have begun to show that the advantages of bilingualism are even more fundamental than being able to converse with a wider range of people. Being bilingual, it turns out, makes you smarter. It can have a profound effect on your brain, improving cognitive skills not related to language and even shielding against dementia in old age. This view of bilingualism is remarkably different from the understanding of bilingualism through much of the 20th century. Researchers, educators and policy makers long considered a second language to be an interference, cognitively speaking, that hindered a child's academic and intellectual development. They were not wrong about the interference: there is ample evidence that in a bilingual's brain both language systems are active even when he is using only one language, thus creating situations in which one system obstructs the other. But this interference, researchers are finding out, isn't so much a handicap as a blessing in disguise. It forces the brain to resolve internal conflict, giving the mind a workout that strengthens its cognitive muscles. Bilinguals, for instance, seem to be more adept than monolinguals at solving certain kinds of mental puzzles. In a 2004 study by the psychologists Ellen Bialystok and Michelle Martin-Rhee, bilingual and monolingual preschoolers were asked to sort blue circles and red squares presented on a computer screen into two digital bins - one marked with a blue square and the other marked with a red circle. In the first task, the children had to sort the shapes by color, placing blue circles in the bin marked with the blue square and red squares in the bin marked with the red circle. Both groups did this with comparable ease. Next, the children were asked to sort by shape, which was more challenging because it required placing the images in a bin m

"MID the squawks and pings of our digital devices, the old-fashioned virtues of reading novels can seem faded, even futile. But new support for the value of fiction is arriving from an unexpected quarter: neuroscience. Brain scans are revealing what happens in our heads when we read a detailed description, an evocative metaphor or an emotional exchange between characters. Stories, this research is showing, stimulate the brain and even change how we act in life. Researchers have long known that the "classical" language regions, like Broca's area and Wernicke's area, are involved in how the brain interprets written words. What scientists have come to realize in the last few years is that narratives activate many other parts of our brains as well, suggesting why the experience of reading can feel so alive. Words like "lavender," "cinnamon" and "soap," for example, elicit a response not only from the language-processing areas of our brains, but also those devoted to dealing with smells. In a 2006 study published in the journal NeuroImage, researchers in Spain asked participants to read words with strong odor associations, along with neutral words, while their brains were being scanned by a functional magnetic resonance imaging (fMRI) machine. When subjects looked at the Spanish words for "perfume" and "coffee," their primary olfactory cortex lit up; when they saw the words that mean "chair" and "key," this region remained dark. The way the brain handles metaphors has also received extensive study; some scientists have contended that figures of speech like "a rough day" are so familiar that they are treated simply as words and no more. Last month, however, a team of researchers from Emory University reported in Brain & Language that when subjects in their laboratory read a metaphor involving texture, the sensory cortex, responsible for perceiving texture through touch, became active. Metaphors like "The singer had a velvet vo

"When high school students in Shanghai crack their history textbooks this fall they may be in for a surprise. The new standard world history text drops wars, dynasties and Communist revolutions in favor of colorful tutorials on economics, technology, social customs and globalization. Socialism has been reduced to a single, short chapter in the senior high school history course. Chinese Communism before the economic reform that began in 1979 is covered in a sentence. The text mentions Mao only once - in a chapter on etiquette. Nearly overnight the country's most prosperous schools have shelved the Marxist template that had dominated standard history texts since the 1950's. The changes passed high-level scrutiny, the authors say, and are part of a broader effort to promote a more stable, less violent view of Chinese history that serves today's economic and political goals. Supporters say the overhaul enlivens mandatory history courses for junior and senior high school students and better prepares them for life in the real world. The old textbooks, not unlike the ruling Communist Party, changed relatively little in the last quarter-century of market-oriented economic reforms. They were glaringly out of sync with realities students face outside the classroom. But critics say the textbooks trade one political agenda for another. They do not so much rewrite history as diminish it. The one-party state, having largely abandoned its official ideology, prefers people to think more about the future than the past."

"Andrew Pole had just started working as a statistician for Target in 2002, when two colleagues from the marketing department stopped by his desk to ask an odd question: "If we wanted to figure out if a customer is pregnant, even if she didn't want us to know, can you do that? " Multimedia How to Break the Cookie Habit This article is adapted from "The Power of Habit: Why We Do What We Do in Life and Business," which will be published on Feb. 28.

Post a Comment » Read All Comments (35) » Pole has a master's degree in statistics and another in economics, and has been obsessed with the intersection of data and human behavior most of his life. His parents were teachers in North Dakota, and while other kids were going to 4-H, Pole was doing algebra and writing computer programs. "The stereotype of a math nerd is true," he told me when I spoke with him last year. "I kind of like going out and evangelizing analytics." As the marketers explained to Pole - and as Pole later explained to me, back when we were still speaking and before Target told him to stop - new parents are a retailer's holy grail. Most shoppers don't buy everything they need at one store. Instead, they buy groceries at the grocery store and toys at the toy store, and they visit Target only when they need certain items they associate with Target - cleaning supplies, say, or new socks or a six-month supply of toilet paper. But Target sells everything from milk to stuffed animals to lawn furniture to electronics, so one of the company's primary goals is convincing customers that the only store they need is Target. But it's a tough message to get across, even with the most ingenious ad campaigns, because once consumers' shopping habits are ingrained, it's incredibly difficult to change them. There are, however, some brief periods in a person's life when old routines fall apart and

"One of the best aspects of science has always been its readiness to admit when it got something wrong. Theories are constantly being refigured, and new research frequently renders old ideas outdated or incomplete. But this hasn't stopped some discoveries from being hailed as important, game-changing accomplishments a bit prematurely. Even in a field as rigorous and detail-oriented as science, theories get busted, mistakes are made, and hoaxes are perpetrated. The following are ten of the most groundbreaking of these scientific discoveries that turned out to be resting on some questionable data. It is worth noting that most of these concepts are not necessarily "wrong" in the traditional sense; rather, they have been replaced by other theories that are more complete and reliable."

"I. MISTAKING BEAUTY FOR TRUTH It's hard to believe now, but not long ago economists were congratulating themselves over the success of their field. Those successes - or so they believed - were both theoretical and practical, leading to a golden era for the profession. On the theoretical side, they thought that they had resolved their internal disputes. Thus, in a 2008 paper titled "The State of Macro" (that is, macroeconomics, the study of big-picture issues like recessions), Olivier Blanchard of M.I.T., now the chief economist at the International Monetary Fund, declared that "the state of macro is good." The battles of yesteryear, he said, were over, and there had been a "broad convergence of vision." And in the real world, economists believed they had things under control: the "central problem of depression-prevention has been solved," declared Robert Lucas of the University of Chicago in his 2003 presidential address to the American Economic Association. In 2004, Ben Bernanke, a former Princeton professor who is now the chairman of the Federal Reserve Board, celebrated the Great Moderation in economic performance over the previous two decades, which he attributed in part to improved economic policy making. Last year, everything came apart. Few economists saw our current crisis coming, but this predictive failure was the least of the field's problems. More important was the profession's blindness to the very possibility of catastrophic failures in a market economy. During the golden years, financial economists came to believe that markets were inherently stable - indeed, that stocks and other assets were always priced just right. There was nothing in the prevailing models suggesting the possibility of the kind of collapse that happened last year. Meanwhile, macroeconomists were divided in their views. But the main division was between those who insisted that free-market economies never go astray and those who believed that economie

"Speaking about Britain's Got Talent singer Susan Boyle in October, he said :"She would not be where she is today if it wasn't for the fact that she looked like such a ******* mong." Mong is a slang term used to refer to people with Down's Syndrome. It is derived from the word "mongrel." He went on: "When she first came on the telly, I went: 'Is that a mong?' "I don't mean she has Down's Syndrome, by the way. No, no! That would be offensive. That word doesn't mean that any more." Channel 4 claimed that using the word was justified in the context of late-night humour. It said the comment was not "directed at Susan Boyle as having a disability but at those who refuse to acknowledge that meanings of words can adapt over time". The company said it needed to experiment and defended the entertainer's right to freedom of expression. Ofcom said in its ruling that Gervais was exploring the interpretations and meanings of certain provocative words. He was examining the changes in their associations over time, with a focus on his assertion that the word "mong" had lost its derogatory association with Down's Syndrome. The regulator said: "This involved Ricky Gervais evoking the word's offensiveness to some extent, and challenging the relationship between the offence and the word itself. "We considered, therefore, that the nature and focus of the routine provided a clear editorial context for his use of the term." "

"FOR a brief, heady period in the history of autism spectrum diagnosis, in the late '90s, I had Asperger syndrome. There's an educational video from that time, called "Understanding Asperger's," in which I appear. I am the affected 20-year-old in the wannabe-hipster vintage polo shirt talking about how keen his understanding of literature is and how misunderstood he was in fifth grade. The film was a research project directed by my mother, a psychology professor and Asperger specialist, and another expert in her department. It presents me as a young man living a full, meaningful life, despite his mental abnormality. "Understanding Asperger's" was no act of fraud. Both my mother and her colleague believed I met the diagnostic criteria laid out in the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. The manual, still the authoritative text for American therapists, hospitals and insurers, listed the symptoms exhibited by people with Asperger disorder, and, when I was 17, I was judged to fit the bill. I exhibited a "qualified impairment in social interaction," specifically "failure to develop peer relationships appropriate to developmental level" (I had few friends) and a "lack of spontaneous seeking to share enjoyment, interests, or achievements with other people" (I spent a lot of time by myself in my room reading novels and listening to music, and when I did hang out with other kids I often tried to speak like an E. M. Forster narrator, annoying them). I exhibited an "encompassing preoccupation with one or more stereotyped and restricted patterns of interest that is abnormal either in intensity or focus" (I memorized poems and spent a lot of time playing the guitar and writing terrible poems and novels). The general idea with a psychological diagnosis is that it applies when the tendencies involved inhibit a person's ability to experience a happy, normal life. And in my c

"Any love-hate relationship must have its share of pain, so the academic world, in its obsession with college rankings, is suitably dismayed by news that an elite college, Claremont McKenna, fudged its numbers in an apparent bid to climb the charts. Claremont McKenna in California is the latest but not the only college to have admitted submitting false information in an effort to win a high rating. Dismayed, but not quite surprised. In fact, several colleges in recent years have been caught gaming the system - in particular, the avidly watched U.S. News & World Report rankings - by twisting the meanings of rules, cherry-picking data or just lying. In one recent example, Iona College in New Rochelle, north of New York City, acknowledged last fall that its employees had lied for years not only about test scores, but also about graduation rates, freshman retention, student-faculty ratio, acceptance rates and alumni giving. Other institutions have found ways to manipulate the data without outright dishonesty. In 2008, Baylor University offered financial rewards to admitted students to retake the SAT in hopes of increasing its average score. Admissions directors say that some colleges delay admission of low-scoring students until January, excluding them from averages for the class admitted in September, while other colleges seek more applications to report a lower percentage of students accepted. Claremont McKenna, according to Robert Morse, the director of data research at U.S. News, is "the highest-ranking school to have to go through this publicly and have to admit to misreporting." This year, U.S. News rated it as the nation's ninth-best liberal arts college. There is no reason to think the U.S. News rankings are rife with misinformation, and the publication makes efforts to police the data, adjust its metrics and close loopholes. But repeated revelations of manipulation show the importance of the rankings in the minds of prospective students, thei

"The photographs of celebrities and models in fashion advertisements and magazines are routinely buffed with a helping of digital polish. The retouching can be slight - colors brightened, a stray hair put in place, a pimple healed. Or it can be drastic - shedding 10 or 20 pounds, adding a few inches in height and erasing all wrinkles and blemishes, done using Adobe's Photoshop software, the photo retoucher's magic wand. "Fix one thing, then another and pretty soon you end up with Barbie," said Hany Farid, a professor of computer science and a digital forensics expert at Dartmouth. And that is a problem, feminist legislators in France, Britain and Norway say, and they want digitally altered photos to be labeled. In June, the American Medical Association adopted a policy on body image and advertising that urged advertisers and others to "discourage the altering of photographs in a manner that could promote unrealistic expectations of appropriate body image." Dr. Farid said he became intrigued by the problem after reading about the photo-labeling proposals in Europe. Categorizing photos as either altered or not altered seemed too blunt an approach, he said. Dr. Farid and Eric Kee, a Ph.D. student in computer science at Dartmouth, are proposing a software tool for measuring how much fashion and beauty photos have been altered, a 1-to-5 scale that distinguishes the infinitesimal from the fantastic. Their research is being published this week in a scholarly journal, The Proceedings of the National Academy of Sciences. "

"Witness testimony has been the gold standard of the criminal justice system, revered in courtrooms and crime dramas as the evidence that clinches a case. Yet scientists have long cautioned that the brain is not a filing cabinet, storing memories in a way that they can be pulled out, consulted and returned intact. Memory is not so much a record of the past as a rough sketch that can be modified even by the simple act of telling the story. For scientists, memory has been on trial for decades, and courts and public opinion are only now catching up with the verdict. It has come as little surprise to researchers that about 75 percent of DNA-based exonerations have come in cases where witnesses got it wrong. This month, the Supreme Court heard its first oral arguments in more than three decades that question the validity of using witness testimony, in a case involving a New Hampshire man convicted of theft, accused by a woman who saw him from a distance in the dead of night. And in August the New Jersey Supreme Court set new rules to cope with failings in witness accounts, during an appeal by a man picked from a photo lineup, and convicted of manslaughter and weapons possession in a 2003 fatal shooting. Rather than the centerpiece of prosecution, witness testimony should be viewed more like trace evidence, scientists say, with the same fragility and vulnerability to contamination. Why is a witness's account so often unreliable? Partly because the brain does not have a knack for retaining many specifics and is highly susceptible to suggestion. "Memory is weak in eyewitness situations because it's overloaded," said Barbara Tversky, a psychology professor at Columbia University's Teachers College in New York. "An event happens so fast, and when the police question you, you probably weren't concentrating on the details they're asking about." "

"Imagine your city isn't as safe as it used to be. Robberies are on the rise, home invasions are increasing and murder rates have nearly doubled in the past three years. What should city officials do about it? Hire more cops to round up the thugs and lock them away in a growing network of prisons? Or design programs that promise more peace by addressing issues like a faltering economy and underperforming schools? Your answer -- and the reasoning behind it -- can hinge on the metaphor being used to describe the problem, according to new research by Stanford psychologists. Your thinking can even be swayed with just one word, they say."
