"IN a great many fields, researchers would give their eyeteeth to have a direct glimpse of the past. Instead, they generally have to piece together remote conditions using remnants like weathered fossils, decaying parchments or mummified remains. Cosmology, the study of the origin and evolution of the universe, is different. It is the one arena in which we can actually witness history. Enlarge This Image Brendan Monroe The pinpoints of starlight we see with the naked eye are photons that have been streaming toward us for a few years or a few thousand. The light from more distant objects, captured by powerful telescopes, has been traveling toward us far longer than that, sometimes for billions of years. When we look at such ancient light, we are seeing - literally - ancient times. "

"Chaser, a border collie who lives in Spartanburg, S.C., has the largest vocabulary of any known dog. She knows 1,022 proper nouns, a record that displays unexpected depths of the canine mind and may help explain how children acquire language. "

"Grisha Perelman, where are you? Three years ago, a Russian mathematician by the name of Grigory Perelman, a k a Grisha, in St. Petersburg, announced that he had solved a famous and intractable mathematical problem, known as the Poincaré conjecture, about the nature of space. After posting a few short papers on the Internet and making a whirlwind lecture tour of the United States, Dr. Perelman disappeared back into the Russian woods in the spring of 2003, leaving the world's mathematicians to pick up the pieces and decide if he was right. Now they say they have finished his work, and the evidence is circulating among scholars in the form of three book-length papers with about 1,000 pages of dense mathematics and prose between them. As a result there is a growing feeling, a cautious optimism that they have finally achieved a landmark not just of mathematics, but of human thought."

"There has been much speculation that the lawyers for Jared Loughner, who has been charged in the Tucson shootings, may mount an insanity defense. Since John Hinckley Jr. was acquitted of trying to kill President Reagan, the use of the insanity defense has become very restricted in federal cases. Arizona, along with several other states, no longer allows a finding of not guilty by reason of insanity. In the three decades since the Hinckley case, brain research and brain scans have made many advances in diagnosing and categorizing mental illness. Yet this seems to have little bearing on how society deals with insanity and culpability in the legal arena. What has been learned in the decades since the Hinckley case? Should a better medical understanding of mental illness alter our legal definitions of insanity? Or is the insanity defense rooted in principles or traditions that actually don't have much to do with medicine?"

"IT has been more than three years since the beginning of the Wall Street financial crisis, yet we continue to hear about new evidence of glaring errors and widespread misdoings. Even the smartest minds in finance are left scratching their heads: how did we not catch any of this sooner? When I hear this refrain, I am reminded of Boris Goldovsky. Goldovsky, who died in 2001, was a legend in opera circles, best remembered for his commentary during the Saturday matinee radio broadcasts of the Metropolitan Opera. But he was also a piano teacher. And it is as a teacher that he made a lasting - albeit unintentional - contribution to our understanding of why seemingly obvious errors go undetected for so long. One day, a student of his was practicing a piece by Brahms when Goldovsky heard something wrong. He stopped her and told her to fix her mistake. The student looked confused; she said she had played the notes as they were written. Goldovsky looked at the music and, to his surprise, the girl had indeed played the printed notes correctly - but there was an apparent misprint in the music. At first, the student and the teacher thought this misprint was confined to their edition of the sheet music alone. But further checking revealed that all other editions contained the same incorrect note. Why, wondered Goldovsky, had no one - the composer, the publisher, the proofreader, scores of accomplished pianists - noticed the error? How could so many experts have missed something that was so obvious to a novice? This paradox intrigued Goldovsky. So over the years he gave the piece to a number of musicians who were skilled sight readers of music - which is to say they had the ability to play from a printed score for the first time without practicing. He told them there was a misprint somewhere in the score, and asked them to find it. He allowed them to play the piece as many times as they liked and in any way that they liked. But not one musician ever found the err

"In our recent dialogue I have noticed a consistent theme. It was frequently remarked that religious lines of argumentation lack reason. The contention seems to be that most, if not all, religious systems rely solely on wholly unsubstantiated faith to support their beliefs. Is this contention in fact true? From a theistic perspective the reality seems quite inverted in that it would appear to require an unreasonable commitment to naturalism to maintain a denial of the transcendent. Rabbi Moshe Averick has done yeoman's work in deconstructing the popular arguments in favor of naturalistic explanations to the origin of life and has concurrently demonstrated the high degree of intellectual vigor of theistic reasoning. This post is a paraphrase of his analysis of the origin of life problem that confronts the naturalist camp within the scientific community. A full treatment is available in his indispensable book Nonsense of a High Order. One might suppose that in the six or so decades since the discovery of the DNA molecule by Watson and Crick during which researchers have been investigating the origin of life they might have come up with some pretty solid leads to explain it. The truth of the matter is that we see scientists coming up surprisingly empty-handed and that even within scientific circles, the few hypotheses they do have are shredded to ribbons by their colleagues within the scientific community.

"After retiring from truck driving in 1987, Teri Horton devoted much of her time to bargain hunting around the Los Angeles area. Sometimes the bargains were discovered on Salvation Army shelves and sometimes, she willingly admits, at the bottom of Dumpsters. Even the most stubborn deal scrounger probably would have been satisfied with the rate of return recently offered to her for a curiosity she snagged for $5 in a San Bernardino thrift shop in the early 1990s. A buyer, said to be from Saudi Arabia, was willing to pay $9 million for it, just under an 180 million percent increase on her original investment. Ms. Horton, a sandpaper-voiced woman with a hard-shell perm who lives in a mobile home in Costa Mesa and depends on her Social Security checks, turned him down without a second thought. Ms. Horton's find is not exactly the kind that gets pulled from a steamer trunk on the "Antiques Roadshow." It is a dinner-table-size painting, crosshatched in the unmistakable drippy, streaky, swirly style that made Jackson Pollock one of the most famous artists of the last century. Ms. Horton had never heard of Pollock before buying the painting, but when an art teacher saw it and told her that it might be his work (and that it could fetch untold millions if it were), she launched herself on a single-minded post-retirement career - enlisting, along the way, a forensic expert and a once-powerful art dealer - to have her painting acknowledged as authentic by scholars and the art market."

"Teri Horton is a 74-year-old retired truck driver with an eighth grade education. She likes to gamble a bit, and now she thinks she has hit the jackpot. Not in a casino, but in the high-stakes world of modern art. Teri isn't the kind of person who knows-or cares-much about art. But as CNN's Anderson Cooper reports, she has caused a stir in the upper reaches of the art world because of a painting she bought years ago, a painting she now believes is the work of the famous abstract expressionist Jackson Pollock. If Teri's painting is by Pollock, it would likely be worth tens of millions of dollars. Not bad, considering she bought it as a gift for a friend and only paid $5 for it in a thrift shop in San Bernardino, Calif."

"For many years, scientists have thought that the first Americans came here from Asia 13,000 years ago, during the last ice age, probably by way of the Bering Strait. They were known as the Clovis people, after the town in New Mexico where their finely wrought spear points were first discovered in 1929. But in more recent years, archaeologists have found more and more traces of even earlier people with a less refined technology inhabiting North America and spreading as far south as Chile. And now clinching evidence in the mystery of the early peopling of America - Clovis or pre-Clovis? - for nearly all scientists appears to have turned up at a creek valley in the hill country of what is today Central Texas, 40 miles northwest of Austin. The new findings establish that the last major human migration, into the Americas, began earlier than once thought. And the discovery could change thinking about how people got here (by coastal migrations along shores and in boats) and how they adapted to the new environment in part by making improvements in toolmaking that led eventually to the technology associated with the Clovis culture. "

"I've come to believe that these failures spring from a single failure: reliance on an overly simplistic view of human nature. We have a prevailing view in our society - not only in the policy world, but in many spheres - that we are divided creatures. Reason, which is trustworthy, is separate from the emotions, which are suspect. Society progresses to the extent that reason can suppress the passions. This has created a distortion in our culture. We emphasize things that are rational and conscious and are inarticulate about the processes down below. We are really good at talking about material things but bad at talking about emotion. When we raise our kids, we focus on the traits measured by grades and SAT scores. But when it comes to the most important things like character and how to build relationships, we often have nothing to say. Many of our public policies are proposed by experts who are comfortable only with correlations that can be measured, appropriated and quantified, and ignore everything else. Yet while we are trapped within this amputated view of human nature, a richer and deeper view is coming back into view. It is being brought to us by researchers across an array of diverse fields: neuroscience, psychology, sociology, behavioral economics and so on. "

"Prosecutors here noted that she is also in the vanguard of a growing trial trend: in Arizona, Hawaii, Idaho, Indiana and some other states in the last few years, courts have allowed such trained dogs to offer children and other vulnerable witnesses nuzzling solace in front of juries. The new role for dogs as testimony enablers can, however, raise thorny legal questions. Defense lawyers argue that the dogs may unfairly sway jurors with their cuteness and the natural empathy they attract, whether a witness is telling the truth or not, and some prosecutors insist that the courtroom dogs can be a crucial comfort to those enduring the ordeal of testifying, especially children. The new witness-stand role for dogs in several states began in 2003, when the prosecution won permission for a dog named Jeeter with a beige button nose to help in a sexual assault case in Seattle. "Sometimes the dog means the difference between a conviction and an acquittal," said Ellen O'Neill-Stephens, a prosecutor there who has become a campaigner for the dog-in-court cause. "

"Born without his fibulas, the long bones that span from the knees to the ankles, Pistorius relies on carbon-fiber prosthetic limbs to propel him around the track in times comparable to some of the world's top runners. And therein remains the question that has been the crux of a continuing debate: do those high-tech legs give him an unfair advantage? "

Humans have often asserted a fundamental difference between themselves and other animals. One of these assertions which has had many proponents into the twentieth century is that humans differ from animals in their use of language. In the past thirty years this assertion has been the subject of much debate as scientists have researched language use by apes. (I use the term "ape" to refer to "great ape" in this essay, as many of my sources do. There have apparently been no language experiments with gibbons or siamangs.) Extraordinary claims have been made by some researchers about the linguistic capabilities of their subjects, mostly chimpanzees. These claims have been refuted and counter-refuted many times, and the literature on the subject is extensive. In this essay I will examine the question of how much, if at all, primates are able to communicate using language. I will then examine the ethical issues surrounding the teaching of language to apes. What is language? First, what is language, and how does it differ from other forms of communication? There does not exist a universally accepted definition of language, or criteria for its use; this is one of the reasons for the disagreement among scientists about whether apes can use language. Language consists of various aspects which people believe are more or less important, for example, grammar, symbol usage, the ability to represent real-world situations, and the ability to articulate something new (Wallman 1992: 6). Duane Rumbaugh describes language as "an infinitely open system of communication" (Rumbaugh 1977b: xx). Some people say that anything an ape can do is not language; of course, if these are the same people who say that language defines us as humans, and an ape can learn sign language, then they are saying that deaf people who use sign language are not human (Patterson & Linden 1981: 119-120). One famous view of language is Charles Hockett's seven key properties: duality, productivity, arbitrariness,

"Guy Deutscher is that rare beast, an academic who talks good sense about linguistics, his chosen field. In his new book, Through the Language Glass (Heinemann), he fearlessly contradicts the fashionable consensus, espoused by the likes of Steven Pinker, that language is wholly a product of nature, that it does not take colour and value from culture and society. Deutscher argues, in a playful and provocative way, that our mother tongue does indeed affect how we think and, just as important, how we perceive the world. An honorary research fellow at the University of Manchester, the 40-year-old linguist draws on a range of sources in the book to show language reflecting the society in which it is spoken. In the process, he explains why Russian water (a "she") becomes a "he" once you have dipped a teabag into her, and why, in German, a young lady has no sex, though a turnip has."

"During the summer of 2008, the eminent Notre Dame sociologist Christian Smith led a research team that conducted in-depth interviews with 230 young adults from across America. The interviews were part of a larger study that Smith, Kari Christoffersen, Hilary Davidson, Patricia Snell Herzog and others have been conducting on the state of America's youth. Josh Haner/The New York Times Smith and company asked about the young people's moral lives, and the results are depressing. It's not so much that these young Americans are living lives of sin and debauchery, at least no more than you'd expect from 18- to 23-year-olds. What's disheartening is how bad they are at thinking and talking about moral issues. The interviewers asked open-ended questions about right and wrong, moral dilemmas and the meaning of life. In the rambling answers, which Smith and company recount in a new book, "Lost in Transition," you see the young people groping to say anything sensible on these matters. But they just don't have the categories or vocabulary to do so. "

"It was April, 1972. The Institute for Advanced Study in Princeton, N. J. The home in the 1950s of Albert Einstein and Kurt Gödel. Thomas Kuhn, the author of "The Structure of Scientific Revolutions" and the father of the paradigm shift, threw an ashtray at my head."

In this edition I would like to explain why hot water freezes faster than cold water, when put into the freezer. It is a very counter-intuitive observation, it's a paradox. This is called the Mpemba Effect. The effect is named according to Tanzanian high-school student Erasto B. Mpemba who re-discovered the effect while making ice cream back in 1963. The Mpemba Effect is a nice example of how the change of one variable, the temperature, can have unexpected side effects. Most people assume that the difference between a hot glass of water and a cold glass of water is only the temperature. But this is not the case. Just by heating the water we are introducing a range of other variables that have an unexpected effect on the outcome.
