Lene Hau has already shaken scientists' beliefs about the nature of things... in 1998, Hau, for the first time in history, slowed light to 38 miles an hour, about the speed of rush-hour traffic...
Two years later, she brought light to a complete halt in a cloud of ultracold atoms... In the experiment, a light pulse was slowed to bicycle speed by beaming it into a cold cloud of atoms. The light made a "fingerprint" of itself in the atoms before the experimenters turned it off. Then Hau and her assistants guided that fingerprint into a second clump of cold atoms. And get this - the clumps were not touching and no light passed between them."The two atom clouds were separated and had never seen each other before," Hau notes. They were eight-thousandths of an inch apart, a relatively huge distance on the scale of atoms.
The experimenters then nudged the second cloud of atoms with a laser beam, and the atomic imprint was revived as a light pulse. The revived light had all the characteristics present when it entered the first cloud of atomic matter, the same shape and wavelength. The restored light exited the cloud slowly then quickly sped up to its normal 186,000 miles a second...
She is coolly confident that light-to-matter communication networks, codes, clocks, and guidance systems can be made part of daily life. If you doubt her, remember she is the person who stopped light, converted it to matter, carried it around, and transformed it back to light.
The collection of computer-automated, high-speed trading technologies and techniques that are typically lumped under the heading of "high-frequency trading" (HFT) have been around for a while, but HFT has recently become heavily identified with the banking giant Goldman Sachs, which dominates some aspects of it on the New York Stock Exchange...I remember Black Monday. I was an active investor in 1987 and lost 10 months worth of profits over the course of three days. And through it all I slept like a baby*. The thought of what could happen nowadays, either triggered by normal human panic, a sudden catastrophe, or a deliberate hacking, scares the bejeezus out of me.
Only about three percent of the trading volume on the NYSE is actually carried out by means of traditional "open outcry" trading, where flesh-and-blood humans gather to buy and sell securities. The other 97 percent of NYSE trades are executed via electronic communication networks (ECNs), which, over the past ten years, have rapidly replaced trading floors as the main global venue for buying and selling every asset, derivative, and contract...
The real issue is that when the average retail investor gets an E*Trade account and tries to play the stock market, she typically has no idea that she's going up against the market equivalent of IBM's chess grandmaster-thumping supercomputer, Deep Blue...
What the vast majority of these algos have in common is that they are not long-term, buy-and-hold "investors" in the classic sense. Rather, they focus on executing as many trades per second as possible and on turning a small profit (often pennies or fractions of a penny) on each trade...
At least two different groups, the TABB Group and FIXProtocol, estimate that high-frequency trading generated around $20 billion in profits for the financial sector last year. Goldman Sachs accounts for some 20 percent of global high-frequency trading activity, and the bank recently had a blow-out quarter in which its HFT-heavy trading operation racked up a record number of days where profits topped $100 million...
At the back of everyone's mind is the 1987 program trading crash, described by Richard Bookstaber in A Demon of our Own Design. In the run-up to October of 1987, all of the major market participants had been using essentially the same computer-automated algorithm to hedge their portfolio risk. On Black Monday (10/19/1987), all of the portfolio insurance programs started dumping assets in lock-step, in response to a particular set of inputs. This synchronized selling begat more synchronized selling, and by the time this giant, market-sized feedback loop was shut down by the closing bell, the Dow had lost almost 23 percent of its value in a single day.
"As the common practice of post-mortem photography in North America and Western Europe has largely ceased, the portrayal of such images has become increasing seen as vulgar, sensationalistic and taboo. This is in marked contrast to the rather beautiful and sensitive presentation of its origins and may represent a cultural shift and wider social discomfort with death..."Pix above found at Mr. Fox, via ofellabuta.
Hat tip to Kottke."The more test materials are promulgated widely, the more possibility there is to game it..." He quickly added that he did not mean that a coached subject could fool the person giving the test into making the wrong diagnosis, but rather "render the results meaningless."
To psychologists, to render the Rorschach test meaningless would be a particularly painful development because there has been so much research conducted - tens of thousands of papers, by Dr. Smith's estimate - to try to link a patient's responses to certain psychological conditions.
This president I think he has exposed himself as a guy over and over and over again who has a deep seated hatred for white people or the white culture, I don't know what it is, but you can't sit in a pew with Jeremiah Wright for 20 years and not hear some of that stuff and not have it wash over.I won't sully this column by embedding the video, but you can view it at Intershame, which offers this commentary:
The cherry on top of this sundae of ignorance has to be the fact that Obama's mother is white. If we apply the transitive property to simpleton Beck's inane rambling we can deduce the following: Obama has a problem with white people and Obama's mother is white. Therefore Obama has a problem with his mother. Good luck trying to make that case.

"Real estate is the cocaine of the banking business."The second article in the series details credit unions, which nationwide have departed from their traditional role of conservative community lenders and embraced high-risk loans.In Minnesota, regulators have seized and closed two banks since 2008 and have ordered 16 others to clean up their balance sheets. Another 65 of the state's 430 banks and thrifts are on a secret watch list, and state banking officials expect more to fail as they are pulled down by bad real estate loans.
Minnesota ranks fifth nationally, with 50, or 12 percent, of its banks carrying particularly high levels of dead real estate loans...
Like their banking rivals, however, some of this state's largest credit unions abandoned the conservative lending principles that long made them bastions of safety. They pursued bigger, riskier and more elaborate loan deals in markets far removed from their everyday customers. And they embraced the booming housing market with gusto, making some of the same exotic home loans that sank such giant institutions as Washington Mutual and Wachovia.Those articles obviously focus on Minnesota, and according to Google analytics only 2% of TYWKIWDBI visits come from Minnesota, so the links that will be more useful to most readers are the ones below, which provided the source data for the Star Tribune articles:
People living in Germany no longer react with awe when they happen to look up at the sky on a clear night. Nothing twinkles in the heavens anymore, and most Germans are only familiar with the majestic appearance of the Milky Way from trips abroad...I occasionally camp out in northern Minnesota, far from the lights of any large city. I am recurrently amazed at the spectacle of the night sky. At my suburban home in southern Wisconsin I can see hundreds of stars, but when I'm on the shore of a northern lake and look up, the star count is multiplied by perhaps 50, the Milky Way is awesome, planets are visible, and meteors cross the sky.
In Germany, a truly dark sky is nowhere to be found. Andreas Hänel, an astronomer in the northwestern city of Osnabrück and head of a German dark-sky association, recently went looking for a place to view the stars in the eastern Alps. He was unable to find even a single spot that has remained completely protected from light smog.
Billions of insects die on streetlights each year or in the webs of the spiders that live on these lights in unnaturally large quantities. Many birds flying at night become confused by the light smog and collide with brightly lit high-rise buildings. Light-sensitive frogs stop their mating activity, thereby producing fewer or no offspring. Freshly hatched sea turtles crawl toward the light on streets instead of into the ocean. Salamanders remain hidden longer than usual, because of insufficient darkness, which deprives them of the time they need to search for food.
In its recently released "Unmanned Aircraft Systems Flight Plan 2009-2047" report, the US Air Force details a drone that could fly over a target and then make the decision whether or not to launch an attack, all without human intervention. The Air Force says that increasingly, humans will monitor situations, rather than be deciders or participants, and that "advances in AI will enable systems to make combat decisions and act within legal and policy constraints without necessarily requiring human input." Programming of the drone will be based on "human intent," with real actual humans monitoring the execution, while retaining the authority and ability to override the system... the Air Force plans to have these dudes operational by 2047...I think I've heard of this before. War machines that function on their own, based on computer intelligence. Humans would be able to override, unless something went wrong. And the report does say we can trust the machines just as we trust people...
Such unmanned aircraft must achieve a level of trust approaching that of humans charged with executing missions, the Air Force stated.I guess that would be o.k. We obviously need things like this to kill people who don't agree with us. Government scientists and politicians are in charge. What could possibly go wrong?

Numbers 11-20 are also listed at the link. I'm sure my late father would be chagrined to see his old alma mater topping the list. When he went there to study electrical engineering in the 1930s, it was a small "cow college."The group's other name, Boko Haram, means "Western education is a sin" and is another title used by local people to refer to the group...I would disagree with the assertion that a spherical earth is "contrary to the teachings of Allah" since some of the greatest astronomers of medieval times were Muslim, and they needed spherical geometry to determine the correct direction to Mecca - but I wouldn't bother trying to explain that to these guys...
If their name is uncertain, however, their mission appears clear enough: to overthrow the Nigerian state, impose an extreme interpretation of Islamic law and abolish what they term "Western-style education".
In an interview with the BBC, the group's leader, Mohammed Yusuf, said such education "spoils the belief in one God".
"There are prominent Islamic preachers who have seen and understood that the present Western-style education is mixed with issues that run contrary to our beliefs in Islam," he said.
"Like rain. We believe it is a creation of God rather than an evaporation caused by the sun that condenses and becomes rain.
"Like saying the world is a sphere. If it runs contrary to the teachings of Allah, we reject it. We also reject the theory of Darwinism."
The Iranian demonstrators have obtained a very important result, however things go. Now the Western public opinion, especially in Israel, the United States and Great Britain, historical enemies of the Iranian regime, is compelled to see Iran in a different way. Not as a country of religious fanatics willing to follow their leaders to the folly of atomic war, but also as the country of boys and girls who use computers, listen and play music, and are willing to take to the streets and also to die for freedom. Now the West knows that the Iranians are not enemies, because we saw that many of them are men and women like us. (Francesco Defferrari)The sentiment expressed in that paragraph (and the linked article) is being debated in a Reddit thread. I can't speak re the European perspective, but I'm sure there are many thousands of Amerians whose perception of Iran could be summarized as "What? You mean there are pretty girls in Iran? I thought it was all old men with beards..." These are people who would not conceive of Iranians having ski resorts, cloverleaf highway interchanges, and jetskis on lakes.
COLORADO SPRINGS, Colo. - Soldiers from an Army unit that had 10 infantrymen accused of murder, attempted murder or manslaughter after returning to civilian life described a breakdown in discipline during their Iraq deployment in which troops murdered civilians, a newspaper reported Sunday...
The Gazette based its report on months of interviews with soldiers and their families, medical and military records, court documents and photographs..."Toward the end, we were so mad and tired and frustrated," said Daniel Freeman. "You came too close, we lit you up. You didn't stop, we ran your car over with the Bradley," an armored fighting vehicle.
With each roadside bombing, soldiers would fire in all directions "and just light the whole area up," said Anthony Marquez, a friend of Freeman in the 1st Battalion, 9th Infantry Regiment. "If anyone was around, that was their fault. We smoked 'em."
Taxi drivers got shot for no reason, and others were dropped off bridges after interrogations, said Marcus Mifflin, who was eventually discharged with post traumatic stress syndrome...
Marquez was the first in his brigade to kill someone after an Iraq tour. In 2006, he used a stun gun to shock a drug dealer in Widefield, Colo., in a dispute over a marijuana sale, then shot and killed him...
"If I was just a guy off the street, I might have hesitated to shoot," Marquez told The Gazette in the Bent County Correctional Facility, where he is serving a 30-year prison term. "But after Iraq, it was just natural."
The Army trains soldiers to be that way, said Kenneth Eastridge, an infantry specialist serving 10 years for accessory to murder.
"The Army pounds it into your head until it is instinct: Kill everybody, kill everybody," he said. "And you do. Then they just think you can just come home and turn it off."
As the Sept. 1 deadline for the implementation of the first phase of the EU's ban on incandescent light bulbs approaches, shoppers, retailers and even museums are hoarding the precious wares -- and helping the manufacturers make a bundle...The phrase "climate-killing bulb" seems to bespeak a bit of bias on the part of the Der Spiegel writer or copyeditor, but I'm blogging this re the phenomenon, not re the sentiment.
"It's unbelievable what is happening," says Werner Wiesner, the head of Megaman, a manufacturer of energy-saving bulbs. Wiesner recounts a story of how one of his field representatives recently saw a man in a hardware store with a shopping cart full of light bulbs of all types worth more than €200 ($285). "That's enough for the next 20 years."
And what's ironic -- in the short term, at least -- is that the companies that manufacture the climate-killing bulbs are seeing a big boost in sales. According to the GfK market research company, sales in Germany of incandescent light bulbs between January and April 20, 2009, saw a 20 percent jump over the same period a year earlier, while CFL sales shrank by 2 percent.
Tenterhooks were used as far back as the fourteenth century in the process of making woollen cloth. After the cloth was woven it still contained oil from the fleece and some dirt. A fuller... cleaned the woolen cloth in a fulling mill, and then had to dry it carefully or the wool would shrink. To prevent this shrinkage, the fuller would place the wet cloth on a large wooden frame, a "tenter", and leave it to dry outside. The lengths of wet cloth were stretched on the tenter (from the Latin "tendere", to stretch) using hooks (nails driven through the wood) all around the perimeter of the frame to which the cloth's edges (selvages) were fixed so that as it dried the cloth would retain its shape and size...
By the mid-eighteenth century the phrase "on tenterhooks" came into use to mean being in a state of uneasiness, anxiety, or suspense, stretched like the cloth on the tenter.
GAZA—Something didn't quite look right about the zebra, but it was hard to say exactly what. Of the several ramshackle zoos in Gaza, Marah, located not far from the Bureij refugee camp, is by far the cheeriest: The animals are lively, the enclosures clean...Before we leave this subject - are zebras black with white stripes? Or white with black stripes? Answer at Wiki - and I'll bet you guessed wrong.
"It's really a painted donkey," admitted Mahmud Berghat, the director of Marah, when asked about the creature. Making a fake zebra isn't easy—henna didn't work and wood paint was deemed inhumane, so they finally settled on human hair dye. "We cut its hair short and then painted the stripes," Berghat explained... It did the trick—if not for zoologists, then at least for legions of Gaza schoolchildren who have never seen a real zebra...
During Israel's Operation Cast Lead... Marah's zookeepers couldn't reach the animals. Some were hit by shrapnel; several, including a prized peacock, escaped; and many more died of starvation... But what differentiates Gaza's zoo is how the animals got there. Prior to the Hamas takeover, many of the animals were brought in legally from Egypt and Israel. But since 2007, the most common route animals take to their cages in Gaza is through the underground labyrinth of tunnels that snake from the southern tip of Gaza into Egypt's Sinai.
But the zoos, whatever their shortcomings, provide a rare form of entertainment in a congested strip of land that affords few other diversions. "This is the only public place in the area where people can relax outside and the children can play..."

Photo credit.COPENHAGEN (Reuters) - The 15th century Vinland Map, the first known map to show part of America before explorer Christopher Columbus landed on the continent, is almost certainly genuine, a Danish expert said Friday...
"All the tests that we have done over the past five years -- on the materials and other aspects -- do not show any signs of forgery," Rene Larsen, rector of the School of Conservation under the Royal Danish Academy of Fine Arts, told Reuters...
The map shows both Greenland and a western Atlantic island "Vinilanda Insula," the Vinland of the Icelandic sagas, now linked by scholars to Newfoundland where Norsemen under Leif Eriksson settled around AD 1000...
He said claims the ink was too recent because it contained a substance called anatase titanium dioxide could be rejected because medieval maps have been found with the same substance, which probably came from sand used to dry wet ink.
American scholars have carbon dated the map to about 1440, about 50 years before Columbus "discovered" the New World in 1492. Scholars believe it was produced for a 1440 church council at Basel, Switzerland.
The Vinland Map is not a "Viking map" and does not alter the historical understanding of who first sailed to North America. But if it is genuine, it shows that the New World was known not only to Norsemen but also to other Europeans at least half a century before Columbus's voyage.
The lack of a provenance has caused much of the controversy. Where the map came from and how it came into the hands of the Swiss dealer after World War Two remain a mystery.
“The maximum speed I achieved on the jet plane without a canopy glass was around two times greater than speed of sound. While on this speed I even managed to pull out my fingers in glove for an inch or two outside - it became heated very fast because of immense friction force plane undergoes with the air,“ writes the pilot…More details and pix at English Russia.
“Usually such tests were conducted in winter time, so it was deadly cold without a canopy and I was pretty glad when this heating began, counting minutes before the plane would reach enough speed/velocity so that the air around becomes hot enough..."
Geithner, who traveled last week to the Middle East and Europe, has to convince foreign investors to keep buying Treasury bills, notes and bonds; they hold nearly half of the government's roughly US$7 trillion in publicly traded debt...On the upside, I should note that Nouriel Roubini, whose comments I heard on the radio about two years ago got me out of the market, now is offering some encouraging words, but those comments are expressed with many conditional phrases.
If foreign demand for U.S. debt sags, that could drive up interest rates and spell big trouble for an economy hobbled by 9.5 percent unemployment...
In the worst case scenario, a rush by foreigners to sell their U.S. debt could send the dollar crashing and inflation soaring. Because that would also hurt the value of their remaining holdings and the U.S. economy — a key market for their exports — private analysts believe such a scenario is not likely to occur...

The United States' top fighter jet, the Lockheed Martin F-22, has recently required more than 30 hours of maintenance for every hour in the skies, pushing its hourly cost of flying to more than $44,000, a far higher figure than for the warplane it replaces, confidential Pentagon test results show.The world's most sophisticated jet fighter is vulnerable to rain... Vulnerable to RAIN. You can't make up stuff like this...
The aircraft's radar-absorbing metallic skin is the principal cause of its maintenance troubles, with unexpected shortcomings -- such as vulnerability to rain and other abrasion -- challenging Air Force and contractor technicians since the mid-1990s...
"It is a disgrace that you can fly a plane [an average of] only 1.7 hours before it gets a critical failure" that jeopardizes success of the aircraft's mission, said a Defense Department critic of the plane who is not authorized to speak on the record. Other skeptics inside the Pentagon note that the planes, designed 30 years ago to combat a Cold War adversary, have cost an average of $350 million apiece and say they are not a priority in the age of small wars and terrorist threats. ..
...Pierre Sprey, a key designer in the 1970s and 1980s of the F-16 and A-10 warplanes, said that from the beginning, the Air Force designed it to be "too big to fail, that is, to be cancellation-proof."
