The Jobless Rate for People Like You
The New York Times has an interactive graph that plots the jobless rate for different groups of Americans compared to the average for all those who are unemployed. Mouseover to find lines for different races, ages, and levels of education. In this screenshot, the label refers to the very faint red line above the dotted line which represents the average jobless rate. Link -via Metafilter

Iconic Album Art on Stamps
The British Royal Mail service commissioned Studio Dempsey to create first class stamps with classic albums covers. The covers include albums from Blur, New Order, Led Zeppelin, The Rolling Stones, Primal Scream, David Bowie, The Clash, Mike Oldfield, Pink Floyd, and Coldplay -but no Beatles.
The final selection of ten sleeves (which perhaps oddly doesn’t feature one of The Beatles’ album covers) will appear on a set of 10 stamps that will launch on January 7, 2010 – and the stamps will be uniquely shaped, as shown in these images, to accommodate a glimpse of a vinyl disc poking out of each record sleeve.

The Science Behind Cowboys In Black and White Hats
In old Western movies, heroes often wore white hats and villains wore black hats. Why? Wray Herbert wrote in Scientific American about a new study that investigated why people often associate the color white with righteousness and black with wickedness:
In Sherman and Clore’s version of the Stroop, volunteers read not the names of colors but words with strong moral overtones: greed and honesty, for example. Some of the words were printed in black and some in white, and they flashed rapidly on a screen. As with the original Stroop, a fast reaction time was taken as evidence that a connection was mentally automatic and natural; hesitation was taken as a sign that a connection did not ring true. The researchers wanted to see if the volunteers automatically linked immorality with blackness, as in black ink, and virtue with whiteness.And they did, so quickly that the connections could not possibly be deliberate. When moral words were printed in white and immoral words in black, reaction time was significantly faster than when words of virtue were black and sin were white. Just as we unthinkingly—almost unconsciously—“know” a lemon is yellow, we instantly know that sin and crime are black and that grace and virtue are white.
The researchers conducted further tests and determined that this color-moral association may stem from concepts of physical cleanliness:
This result offers pretty convincing evidence in itself that the connection between black and bad is not just a metaphor we all have learned over the years, but rather it is deeply associated with our ancient fear of filth and contagion. But Sherman and Clore wanted to look at the question yet another way. If the association between sin and blackness really does reflect a concern about dirt and impurity, then this association should be stronger for people who are preoccupied with purity and pollution. Such fastidiousness often manifests as personal cleanliness, and a proxy for personal cleansing might be the desire for cleaning products. The researchers tested this string of psychological connections in a final study, again ending with the Stroop test.

You'll Need an Electron Microscope to Read the World's Smallest Book
Image: Robert Chaplin
Teeny Ted from Turnip Town by Malcolm Douglas Chaplin is, according to the Guinness Book of World Records, the world’s smallest book. Each page measures about 11 by 15 microns:
The Robert Chaplin/SFU Nanobook project was produced using a focused-gallium-ion beam with the assistance of Dr. Li Yang, and Dr. Karen L. Kavanagh of Simon Fraser University, located at the summit of Burnaby Mountain, Burnaby, BC. The gallium beam has a minimum diameter of 7 nanometers, and was programmed to carve the space surrounding each letter of a book. The book was typeset in block letters with a resolution of 40 nanometers, and is made up of 30 microtablets, each carved on a polished piece of single crystalline silicon. The entire collection of microtablets is contained within an area of 69 x 97 microns square with an average size of tablet being 11 x 15 microns square.

William Hoffman is a New York filmmaker who put this video together and uploaded it last August. It’s finally getting some viral activity, and rightfully so. It’s “a celebration of life that was inspired by David Eagleman’s book, Sum.”
I do enjoy a perfectly realized edit, and this one’s full of them. William’s website.

Lost Persian Army Discovered Almost 2,500 Years Later
A massive army of Persian King Cambyses II was said to be swallowed up by the desert in the year 525 B.C. The army, containing a whopping 50,000 soldiers, made it to a desert oasis and then was never heard from again –until now.
“A wind arose from the south, strong and deadly, bringing with it vast columns of whirling sand, which entirely covered up the troops and caused them wholly to disappear,” wrote Herodotus.
Up until now, most historians thought this was mostly just a story, but the discovery of a massive collection of bones and silver and bronze jewelry in the desolate Sahara Desert has them reconsidering.

Human-Shaped Root
Farmer Zheng Dexun of Langzhong, China dug up a fleeceflower root that looks like a human being right down to the arms, legs, and facial features. It is 62 centimeters tall and weights 5.8 kilograms. Zeng, worried about the consequences of digging it up, put it back in the ground, saying ” don’t know whether it is good or bad to dig out a Chinese knotweed that looks like a human. I’d better put it back in the earth!” Full-sized image at the link.

D&D Character Sheet As Resume

Sean McNally, a 15th-level artist and 7th-level animator, created a resume that looks like a character sheet from Dungeons & Dragons. He claims to have a Base Art Bonus of +11, of which I am skeptical. But maybe a little exaggeration is expected on a resume. Click on the link for a larger image.

The EU may approve "road trains" for European highways
Truck-based road trains are currently used for long-distance transport in rural Australia and in several other countries; they are created by physically connecting several trailers or semi-trailiers to the lead tractor unit.
The EU is proposing a different type of “train,” which would be comprised of a mixture of trucks, buses, and passenger cars closely following one another in a slipstream, much as race cars do at professional tracks. The project’s acronym is SARTRE (SAfe Road TRains for the Environment).
The lead vehicle would be handled by a professional driver who would monitor the status of the road train. Those in following vehicles could take their hands off the wheel, read a book or watch TV, while they travel along the motorway. Their vehicle would be controlled by the lead vehicle.
The idea, of course, is to improve fuel economy and to relieve congestion by allowing a greater number of vehicles to occupy a given area of the roadway. But notice how this concept also solves the problem of texting-while-driving, by removing the “driving” component and allowing the driver to spend his/her entire time texting. Sounds perfectly logical to me. What could possibly go wrong?

How Big Is Antarctica?
Photo: Icebridge (NASA)
Antarctica is roughly 5.4 million square miles (14 million square kilometers) in size, and that’s with all of its ice. There is a land mass beneath, which looks like this. Twitter user Icebridge made this image to illustrate just how large our most unvisited continent actually is.
Conversely, “it is estimated that at any given time there are (only) 1,000 people ‘living’ in Antarctica, but this varies depending on the season.” (from Answerbag.)

Remote-control Bowling Ball
At one time or another, everyone wishes they could control a bowling ball after it leaves his/her hand. The RC900 remote-control bowling ball makes that dream come true! A weight in a threaded shaft inside the ball determines its direction, and the user controls the weight. The purpose of the ball is to give young children a bit of success as they learn to bowl, and to help disabled people paticipate in the sport. Don’t even think of sneaking the RC900 into a competition! Link (with video) -via Gizmodo

Top 10 Clever Fixes for Your Broken Stuff
Lifehacker collected ten handy household repair secrets from around the web that may come in handy when you least expect them. For example, a tip for getting your dying hard drive to survive long enough to make the backup you should have made long ago.
If it looks like mechanical failure is the cause, and you need just a bit more data off that drive before it’s gone for good, try sticking it in the freezer until it’s good and cold, then let it reach room temperature again and give it another try. This passed-around tech geek tip works, as a last resort, because when worn-out mechanical parts fail to connect and align properly, contracting them with cold, then allowing them to expand again, can sometimes restore things to barely-working order just long enough to give you a little more time before the funeral.
You’ll also find quick fixes for stripped screw holes, broken light bulbs, and even hangovers! Link -via the Presurfer

10 Neat Facts About Carl Sagan
Carl Sagan with a model of the Viking Lander. Photo via Wikipedia
I miss Carl Sagan. Sagan's enthusiasm for science and his knack for translating difficult scientific concepts into simple explanations that many can understand, made him a popular figure. He was an ambassador for science, if you will, as he had inspired many people to study science (yours truly included).
Today would've been his 75th birthday, so in honor of the great astronomer, scientist and author, Neatorama presents 10 Neat Facts About Carl Sagan:
1. Carl Sagan's First Book About Stars
When Carl was five years old, he wondered about the stars: what were they? Unsatisfied with the answers he got from his friends and from adults he knew, Carl went to the library and asked for a book about stars. The librarian handed him ... a book on celebrities! In Keay Davidson's Carl Sagan: A Life, Carl explained how his fascination with the cosmos began:
I gave it back to her and said, "This wasn't the kind of stars I had in mind." She thought this was hilarious, which humiliated me further. She then went and got the right kind of book. I took it—a simple kid's book. I sat down on a little chair—a pint-sized chair—and turned the pages until I came to the answer.
And the answer was stunning. It was that the Sun was a star but really close. The stars were suns, but so far away they were just little points of light.... And while I didn't know the [inverse] square law of light propagation or anything like that, still, it was clear to me that you would have to move that Sun enormously far away, further away than Brooklyn [for the stars to appears as dots of light]....
The scale of the universe suddenly opened up to me. [It was] kind of a religious experience. [There] was a magnificence to it, a grandeur, a scale which has never left me. Never ever left me.
2. Sagan vs. Apple
In
1994, Apple chose the internal codename "Carl Sagan" for its
PowerMac 7100. Though it was meant as an homage to Carl (and an in-joke
that the computer would make Apple "billions and billions" of
dollars), they also used the codenames "Piltdown Man" and "Cold
Fusion" for the Power Mac 6100 and 8100, respectively. When Carl
found out that he was being put alongside scientific hoaxes, he sued Apple.
Though Apple won the suit, the codename was changed to BHA (Butt Head
Astronomer) ... which prompted yet another lawsuit from the p.o.'d astronomer!
Apple won again, but their lawyers demanded the engineers change the codename
one more time, which they did. The PowerMac 7100 was known by its final
codename LAW, which stood for "Lawyers Are Wimps."
3. Spaced Out ... On Pot!
In 1969, Carl Sagan wrote under the Pseudonym "Mr. X" about the virtues of cannabis. Harvard Medical School Professor Emeritus of Psychiatry Lester Grinspoon has the article in his website Marijuana Uses:
It all began about ten years ago. I had reached a considerably more relaxed period in my life - a time when I had come to feel that there was more to living than science, a time of awakening of my social consciousness and amiability, a time when I was open to new experiences. I had become friendly with a group of people who occasionally smoked cannabis, irregularly, but with evident pleasure. Initially I was unwilling to partake, but the apparent euphoria that cannabis produced and the fact that there was no physiological addiction to the plant eventually persuaded me to try. My initial experiences were entirely disappointing; there was no effect at all, and I began to entertain a variety of hypotheses about cannabis being a placebo which worked by expectation and hyperventilation rather than by chemistry. After about five or six unsuccessful attempts, however, it happened. I was lying on my back in a friend's living room idly examining the pattern of shadows on the ceiling cast by a potted plant (not cannabis!). I suddenly realized that I was examining an intricately detailed miniature Volkswagen, distinctly outlined by the shadows. I was very skeptical at this perception, and tried to find inconsistencies between Volkswagens and what I viewed on the ceiling. But it was all there, down to hubcaps, license plate, chrome, and even the small handle used for opening the trunk. When I closed my eyes, I was stunned to find that there was a movie going on the inside of my eyelids. Flash . . . a simple country scene with red farmhouse, a blue sky, white clouds, yellow path meandering over green hills to the horizon. . . Flash . . .
4. The Politics of Science
Anyone who has ever worked in a university or an academic institution would know this, but most people assume that because science relies on logic and careful reasoning, scientists would behave in a clinical and dispassionate way. Nothing is farther from the truth.
Carl's popularity had backfired on him not once but twice. In 1967, he was denied tenure at Harvard because his colleagues bristled at "what they perceived as self-aggrandizement and pandering to the public."
In 1992, Carl was again disappointed when his application for membership at the prestigious National Academy of Sciences was denied. Ironically, he received the Public Welfare Medal, the highest award of the Academy for "distinguished contributions in the application of science to the public welfare."
In both instances, Carl persevered and succeeded to overcome setbacks resulting from the politics of science.
5. Billions and Billions
Carl Sagan actually never used the term "billions and billions." His exact words on the series Cosmos were "billions upon billions" (which, for all practical purpose, is pretty much the same thing).
So how did "billions and billions" came to be? We can blame Johnny Carson:
Carl was a good sport - his final book, titled Billions
& Billions: Thoughts on Life and Death at the Brink of the Millennium
6. The Sagan Unit
A sagan is defined as at least 4 billion (the smallest amount in "billions" is two billion, so "billions and billions" equal 4 billion). It is estimated that the Milky Way galaxy has 100 sagan (400,000,000,000) stars.
Previously on Neatorama: Fun and Unusual Units of Measurements
7. Pioneer Plaques
Many people know that Pioneer 10 and Pioneer 11 spacecrafts carry metal plaques that carry a message from mankind. But not many know that it was Carl Sagan, together with Frank Drake (yes, the man who came up with the Drake Equation that attempts to estimate the number of alien civilization in our galaxy), that designed the plaque. The controversial artwork, which featured a nude man and woman, was drawn by Sagan's then-wife Linda Salzman Sagan.
After the Pioneer Program, NASA put a Golden Record aboard the two Voyager spacecrafts, which included a greeting "Hello from the children of planet Earth." That was recorded by then six-year-old Nick Sagan, Carl's son.
8. Carl Sagan Memorial Station ... on Mars!
Nick Sagan grew up to become a novelist and screenwriter. He wrote an episode of Star Trek: Enterprise titled "Terra Prime," which included a CGI of Carl Sagan Memorial Station plaque on Mars.
Image via Memory
Alpha, the Star Trek Wiki
The plaque above is fictional - but the Carl Sagan Memorial Station is real. It's the formal name of the NASA Mars Pathfinder lander, which delivered the Sojourner rover that explored the Red Planet.
9. Sagan Asteroid
Just in case a unit of measurement and a memorial station on Mars aren't enough, Carl had another thing named after him: a small asteroid in the main asteroid belt between Mars and Jupiter was named the 2709 Sagan.
10. Sagan's Last Interview
In 1996, not long before his death, Carl Sagan was interviewed by Charlie Rose, in which he discussed the rise of pseudoscience in the United States. He looked gaunt in the interview, but as you can see, he remained as sharp as ever:
Bonus: Carl Sagan A Glorious Dawn Auto-Tune
This has been on Neatorama before, but it's so good that we just have to feature it again for those of you who might've missed it. Behold, Carl Sagan's A Glorious Dawn auto-tuned:
__________
I'll be the first to acknowledge that this is a woefully inadequate post about one of the most brilliant scientists who ever lived. We didn't talk about Cosmos (because it's so popular, I opted for the more obscure Sagan trivia), his books and Pulitzer Prize, Carl Sagan Day and so on. If you have a Sagan story, please share it in the comments.

The Fall of the Berlin Wall -- 20 Years Later
Twenty years ago today, the Berlin Wall was breached and collapse of European Communism rapidly accelerated. From the archives of the BBC:
At midnight East Germany’s Communist rulers gave permission for gates along the Wall to be opened after hundreds of people converged on crossing points.
They surged through cheering and shouting and were be met by jubilant West Berliners on the other side.
Ecstatic crowds immediately began to clamber on top of the Wall and hack large chunks out of the 28-mile (45-kilometre) barrier.

Jilted Bride Turns Wedding Into Party
34-year-old Teane Harris of Bensenville, Illinois had planned a big wedding, but it was called off when the groom backed out only a week before the big event. Harris and her mother were told it was too late to get their deposit back for the reception. What to do? Harris decided to use the facilities and all the wedding supplies to throw a party for the Asbury Court Retirement Community.
Just like that, the Halloween party planned for the 340 residents at Asbury Court turned into a lavish banquet, with a sumptuous meal, elegant flowers, sparkling masks right out of a masquerade ball, and a disc jockey who kept the mood lively.
“We knew we weren’t going to be getting our money back,” says Harris, during a phone interview from Hawaii, where she followed through with her honeymoon trip. “So after doing damage control and not wanting anything to go to waste, we looked for somebody who would benefit from it, and we saw the retirement center.”
Asbury officials still marvel over the turn of events, and of the selfless act by Harris. On Friday, they mounted a marquis sign thank you to Harris to show their appreciation.
“It was out of the blue; she knows no one here,” says Eric Haugan, resident services director. “And yet when she came to the party herself, she had all these grandmas wanting to give her a hug. She just broke down.”
