thecarchik writes"About two years ago BBC's Top Gear aired a test drive of the then relatively new Tesla Roadster. In the particular episode, Tesla Roadsters are depicted as suffering several critical 'breakdowns' during track driving. Host Jeremy Clarkson concludes the episode by saying that in the real world the Roadster 'doesn't seem to work.' Tesla claims that the breakdowns were staged, making most of Top Gear's remarks about the Roadster untrue. Tesla also states that it can prove Top Gear's tests were falsified due to the recordings of its cars' onboard data-loggers. What's Tesla asking for in the lawsuit? Tesla simply wants Top Gear to stop rebroadcasting the particular episode and to correct the record."

Silicine might be the new graphene, now that it's been physically constructed

By Sean Hollister  posted Mar 28th 2011 6:29AM

Surely you've heard of graphene, the one-atom-thick layer of pencil lead that has the potential to change the world of computers, batteries and screens? You might want to familiarize yourself with the term "silicine," too. It's basically a version of graphene constructed out of silicon, which doesn't naturally align itself into the same eminently useful honeycomb shape -- but, given a little prod here and a layer of silver or ceramic compound there, can do much the same thing, and with better computing compatibility. First proposed around 2007, it's reportedly been produced twice now by two different teams, which gives physicists hope that it could actually be useful some day. For now, researchers need to figure out a way to easily produce it so detailed experiments can be performed -- from what we understand, the good ol' scotch tape method just won't do the job.

US Competitiveness Chief Immelt's GE Tax Bill: $0

theodp writes"'He understands what it takes for America to compete in the global economy,' President Obama said of GE CEO Jeff Immelt, as he announced Immelt would chair the President's Council on Jobs and Competitiveness. On Friday, the NY Times reported that one trick Immelt employs to keep GE competitive is paying no American tax bill. In fact, GE claimed a 2010 tax benefit of $3.2B on worldwide profits of $14.2B, $5.1B of which came from US operations. According to the NYT, GE's extraordinary tax-avoidance success is based on an aggressive strategy that mixes fierce lobbying for tax breaks and innovative accounting that enables it to concentrate its profits offshore. GE's giant tax department is led by a former Treasury official whose 975-member team includes former officials not just from the Treasury, but also from the IRS and virtually all the tax-writing committees in Congress. GE's return to rock-bottom tax rates marks a dramatic reversal from the mid-80's when President Reagan reacted to corporate accounting gamesmanship and supported a change that closed loopholes and required GE to pay a far higher effective rate, up to 32.5%. 'That GE can almost set its own tax rate shows how very much we need reform,' said Rep. Lloyd Doggett. 'Our tax system should encourage job creation and investment in America and end these tax incentives for exporting jobs and dodging responsibility for the cost of securing our country.'"

OMG, FYI, and LOL enter Oxford English Dictionary, foreshadow the apocalypse

By Vlad Savov  posted Mar 24th 2011 3:41PM

In an acknowledgement of the internet's overwhelming influence on the triviality we sometimes refer to as "real life," the Oxford English Dictionary doyens have decided to add a few of the web's favorite pronouncements to their lexicon. Among them are the standouts OMG, LOL and FYI, joining their compatriots IMHO and BFF among the proud number of officially sanctioned initialisms (abbreviations contracted to the initials of their words) used in the English language. Shockingly enough, the expression OMG has had its history tracked all the way back to 1917, while LOL used to mean "little old lady" back in the '60s, and FYI first showed up in corporate lingo in 1941. Not only that, but the heart symbol -- not the <3 emoticon, the actual ♥ graphic -- has also made it in. Just so long as Beliebers and fanpires are kept out, there's still hope for the future. A tiny, twinkling ember of a hope.

P2P Music Downloads At All-Time Low

Fruit Flies Hold the Key To Faster Computing

hapworth writes"Dr. Ziv Bar-Joseph, a researcher at Carnegie Mellon, may have found the key to faster computing in the form of fruit flies. While computer scientists have long struggled with determining optimal communications paths in digital environments, Bar-Joseph believes the answer can be found by studying the biological make-up of fruit flies: 'Determining how to select a [Maximal Independent Set] is difficult and has been under scrutiny for many years. It turns out that fruit flies solve a similar problem. During brain development, a process called Sensory Organ Precursor [SOP] selection occurs,' he says. 'As in computer networks, some cells (SOP) in the brain will become local leaders (MIS) and convey information from the environment to neighboring cells.'"

Europe-Wide Survey Reveals Priorities for End-of-Life Care


ScienceDaily (Mar. 23, 2011) — A survey of over 9,000 people in seven different countries across Europe has shown that the majority would want to improve the quality of life in the time they had left, rather than extend it. The survey reveals attitudes across Europe for dealing with serious illnesses such as cancer, and issues raised when caring for a close friend of relative in the last few months of life. The research was carried out as part of an EU-funded project led by researchers from King's College London.

Thailand Tried to Barter Chickens for Fighter Jets

By Robin Wheeler, Tue., Mar. 8 2011
Reuters released a special report last week about how post-Cold War diplomats were put to work advocating for U.S. business interests abroad, at times straddling the line between being diplomats and hucksters.

Case in point: American company Lockheed Martin wanted to unload some F-16 fighter jets to Thailand's government...

In 2005, the Thai government started shopping for new military fighter jets among Lockheed Martin, Russia's Sukhoi and Sweden's Saab. It made clear up front that any deal it signed had to include "countertrade" worth at least 50 percent of the deal's value -- we buy X and you help us sell Y.

For the embassy in Bangkok, winning achieved two goals: helping Lockheed and keeping the Russians from selling planes. There was, however, a small complication with the terms -- The Thai government didn't want to pay cash. Instead, it proposed trading 80,000 stockpiled tons of frozen chicken.

Despite talks, Lockheed Martin declined the chicken offer.
How big is 80,000 tons of poultry?

The average dressed, raw chicken weighs four pounds.

The average Lockheed Martin F-16 weighs 42,300 pounds.

That means you'd need about 3,783 bad-ass fighter jets to equal the weight of 80,000 tons of chickens (which, at four pounds per, amounts to 40 million birds).

Seems like a fair trade.
Alright 80,000 chickens AND all the Pud Thai noodles you could eat

A child couldn’t paint that – can people tell abstract art from a child’s or chimp’s work?


submit to reddit
 
  
If you wander through New York’s Museum of Modern Art, you’ll eventually come across Painting Number 2 by Franz Kline, a set of thick, unruly black lines on a white canvas. Elsewhere, you will find one of Mark Rothko’s many untitled works, consisting of various coloured rectangles. And in front of both paintings, you will inevitably find visitors saying, “A child could paint that.”
To which Angelina Hawley-Dolan and Ellen Winner replied: “Could they?”
The duo wanted to test the assertion that abstract expressionist art is devoid of talent – that it could be done by a mere child, or even an animal. With keyboards and enough time, monkeys could surely duplicate Shakespeare, but with a paintbrush and a few hours, could a monkey produce a Rothko?
To find out, Hawley-Dolan and Winner asked 32 art students and 40 psychology students to compare pairs of paintings. One piece of each pair was the work of a recognised artist, such as Kline, Rothko, Cy Twombly, Gillian Ayre, and more. The other came from the oeuvre of lesser-known painters, including preschool children, elephants, chimps, gorillas and monkeys. The paintings were matched according to colour, line quality, brushstroke and medium; the students had to say which they preferred and which was better.
Both groups of students preferred the professional pieces to the amateur ones, and judged them to be superior. Even the psychology students, who had no background in art education, felt the same way, although as you might expect, their preference for the professional works was slightly weaker.
Throughout the experiments, the students typically picked the professional pieces between 60% and 70% of the time. These aren’t overwhelming majorities, but they were statistically significant. On average, a child could not “paint that”, even if first glances might suggest otherwise. Nor are the qualities of the abstract art only visible to people steeped in the art world – even untrained people responded to the paintings in some way.
Hawley-Dolan and Winner also found that it didn’t matter if the students were duped into thinking that the paintings came from the wrong “artist”. The duo labelled the pairs of paintings on some of the tests (“artist”, “child”, “monkey” or “elephant”) and mislabelled them on others. Even with these tags, the students still preferred the actual professional painting. The labels only swayed the decisions of the psychology students – they were more likely to judge the professional paintings more positively if they were correctly labelled (but not more harshly if the labels were swapped).
This goes against an earlier experiment by Ulrich Kirk, who found that people find paintings to be more aesthetically pleasing when they’re labelled as having come from a gallery, rather than having been generated by computers. Other anecdotes have also painted an unflattering picture of abstract art. The mother of two-year-old toddler Freddie Linsky managed to dupe the art world by selling her son’s work – including a splash of ketchup on a high chair – on Saatchi Online (admittedly, for a paltry £20). A chimp called Congo fared much better, selling off three paintings for £12,000 at Bonhams auction house.
But none of these stories involved paired comparisons. Hawley-Dolan and Winner think that such side-by-side judgments are better ways of telling if people can discriminate between pieces produced by different painters.
When asked why they made their choices, both groups of students speculated about what the artist was trying to achieve, or what was going through their mind at the time. They saw more of such intentions in the professional pieces than in the more random shapes of the children and animals. As Hawley-Dolan and Winner write:
“People untrained in visual art see more than they realize when looking at abstract expressionist paintings. People may say that a child could have made a work by a recognized abstract expressionist, but when forced to choose between a work by a child and one by a master such as Rothko, they are drawn to the Rothko even when the work is falsely attributed to a child or nonhuman. People see the mind behind the art.”

Did Newt Gingrich's Love for America Lead to Adultery?

Did the Newt Gingrich PR bus just hit a pothole? 

Former House speaker Gingrich, widely believed to be prepping a 2012 GOP presidential run, comes with what has been politely termed "baggage" - not the least of which includes multiple marriages and admitted adultery. In a recent interview, perhaps realizing he'll need to address his colorful past if he's going to make a serious run for the country's top job, he took a pass at a positively Newtonian defense: he was driven to cheat on his wives because of his love for America!

In a roundabout way, at least. 

What he said was that he was so busy working to serve his passion for America that "things happened." Things that weren't "appropriate":

"There’s no question at times of my life, partially driven by how passionately I felt about this country, that I worked far too hard and things happened in my life that were not appropriate.
