"Acousticians have been designing concert halls for more than a century, but Dr. Kyriakakis does something different. He shapes the sound of music to conform to the space in which it is played. The goal is what Dr. Kyriakakis calls the "ground truth" - to replicate the original in every respect. "We remove the room," he said, "so the ground truth can be delivered." Dr. Kyriakakis, an electrical engineer at U.S.C. and the founder and chief technical officer of Audyssey Laboratories, a Los Angeles-based audio firm, could not achieve his results without modern sound filters and digital microprocessors. But the basis of his technique is rooted in the science of psychoacoustics, the study of sound perception by the human auditory system. "It's about the human ear and the human brain, and understanding how the human ear perceives sound," Dr. Kyriakakis said. Psychoacoustics has become an invaluable tool in designing hearing aids and cochlear implants, and in the study of hearing generally. "Psychoacoustics is fundamental," said Andrew J. Oxenham, a psychologist and hearing expert at the University of Minnesota. "You need to know how the normally functioning auditory system works - how sound relates to human perception." "

I think it's good, although it slightly mixes up our nice distinction between sense perception and perception in general, and she actual says "we see things not as they are but as we are" at one point. The title "The Truth in the Lie" evokes one of the current essay titles, and it has a lot to say about ethics 'n stuff.

"Professor Greene is lecturing. Down the hall, her arch-rival, Professor Browne, is also lecturing. Professor Greene is holding forth at length about how absurd Professor Browne's ideas are. She believes Professor Browne to be lecturing in Room 33. So to emphasize her point, she writes on the blackboard the single sentence: Everything written on the board in Room 33 is false. But Professor Greene has made a mistake. She, herself, is in Room 33. So is what she has written on the board true or false? If it's true, then since it itself is written on the board, it's false. If it's false, then since it is the only thing written on the board, it's true. Either way, it's both true and false. Philosophers and logicians love paradoxes, and this is one - one of the many versions of what is usually called the Liar Paradox, discovered by the ancient Greek philosopher Eubulides (4th century B.C.). Paradoxes are apparently good arguments that lead to conclusions that are beyond belief (Greek: "para" = beyond, "doxa" = belief). And when you meet a paradox, you've got only two choices. One is to accept that the conclusion, implausible as it may seem, is actually true; the other is to reject the conclusion, and explain what has gone wrong in the argument."

"Apart from the most rabid fundamentalists among us, nearly everyone admits that the Bible might contain errors -- a faulty creation story here, a historical mistake there, a contradiction or two in some other place. But is it possible that the problem is worse than that -- that the Bible actually contains lies? Most people wouldn't put it that way, since the Bible is, after all, sacred Scripture for millions on our planet. But good Christian scholars of the Bible, including the top Protestant and Catholic scholars of America, will tell you that the Bible is full of lies, even if they refuse to use the term. And here is the truth: Many of the books of the New Testament were written by people who lied about their identity, claiming to be a famous apostle -- Peter, Paul or James -- knowing full well they were someone else. In modern parlance, that is a lie, and a book written by someone who lies about his identity is a forgery. Most modern scholars of the Bible shy away from these terms, and for understandable reasons, some having to do with their clientele. Teaching in Christian seminaries, or to largely Christian undergraduate populations, who wants to denigrate the cherished texts of Scripture by calling them forgeries built on lies? And so scholars use a different term for this phenomenon and call such books "pseudepigrapha." You will find this antiseptic term throughout the writings of modern scholars of the Bible. It's the term used in university classes on the New Testament, and in seminary courses, and in Ph.D. seminars. What the people who use the term do not tell you is that it literally means "writing that is inscribed with a lie.""

"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

December 2005 Over the millennia, many mathematicians have hoped that mathematics would one day produce a Theory of Everything (TOE); a finite set of axioms and rules from which every mathematical truth could be derived. But in 1931 this hope received a serious blow: Kurt Gödel published his famous Incompleteness Theorem, which states that in every mathematical theory, no matter how extensive, there will always be statements which can't be proven to be true or false. Gregory Chaitin has been fascinated by this theorem ever since he was a child, and now, in time for the centenary of Gödel's birth in 2006, he has published his own book, called Meta Math! on the subject (you can read a review in this issue of Plus). It describes his journey, which, from the work of Gödel via that of Leibniz and Turing, led him to the number Omega, which is so complex that no mathematical theory can ever describe it. In this article he explains what Omega is all about, why maths can have no Theory of Everything, and what this means for mathematicians."

"The behavioral revolution in economics and psychology has successfully identified and named close to three dozen biases (my favorite behavioral folk song defines them in verse). I had thought that these biases transcended issues of culture. Indeed, both neoclassical and behavioral economists were united in a belief that cultural variables were of secondary importance when it came to the deep drivers of behavior. But a series of experiments now has me thinking that the underlying heuristics are less universal."

"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.

"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. "

"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. "

"God is dead in a very particular sense. He no longer plays his traditional social role of organizing us around a commitment to a single right way to live. "

"A good portion of 21st-century news consumers no longer believe in objectivity. They know it isn't possible. And yet the public expects reporters to always play it down the middle, delivering the facts and only the facts, unencumbered by bias. But to what lengths should reporters go? Can they report fairly on beats that encroach on their personal lives? Should they vote? Brooke canvassed an array of (objective) sources and compiled this report."

"Many years later, Yarbrough met with a team of psychologists who were conducting training sessions for law enforcement. They sat beside him in a darkened room and showed him a series of videotapes of people who were either lying or telling the truth. He had to say who was doing what. One tape showed people talking about their views on the death penalty and on smoking in public. Another featured a series of nurses who were all talking about a nature film they were supposedly watching, even though some of them were actually watching grisly documentary footage about burn victims and amputees. It may sound as if the tests should have been easy, because we all think we can tell whether someone is lying. But these were not the obvious fibs of a child, or the prevarications of people whose habits and tendencies we know well. These were strangers who were motivated to deceive, and the task of spotting the liars turns out to be fantastically difficult. There is just too much information--words, intonation, gestures, eyes, mouth--and it is impossible to know how the various cues should be weighted, or how to put them all together, and in any case it's all happening so quickly that you can't even follow what you think you ought to follow. The tests have been given to policemen, customs officers, judges, trial lawyers, and psychotherapists, as well as to officers from the F.B.I., the C.I.A., the D.E.A., and the Bureau of Alcohol, Tobacco, and Firearms-- people one would have thought would be good at spotting lies. On average, they score fifty per cent, which is to say that they would have done just as well if they hadn't watched the tapes at all and just guessed. But every now and again-- roughly one time in a thousand--someone scores off the charts. A Texas Ranger named David Maxwell did extremely well, for example, as did an ex-A.T.F. agent named J.J. Newberry, a few therapists, an arbitrator, a vice cop-- and John Yarbrough, which suggests that what happened in Willowbrook
