Men with big muscles cut cancer risk by 40 per cent

Lifting weights cuts cancer risk in men — by 40 per cent!

A team of experts, led by scientists from Sweden’s Karolinska Institute, tracked the lifestyles of 8,677 men aged between 20 and 82 for more than two decades.

Each volunteer had regular medical check ups that included tests of their muscular strength.

Between 1980 and 2003, researchers monitored how many developed cancer and subsequently died from it.

The results showed men who regularly worked out with weights and had the highest muscle strength were between 30 and 40 per cent less likely to lose their life to a deadly tumour.

When did white trash become normal?

Wednesday, December 11th, 2013

When did white trash become normal?, Charlotte Hays asks:

Students of Arnold Toynbee, the English historian, will recognize what is going on here. In a chapter of his “A Study of History” entitled “Schism in the Soul,” Toynbee argued that it is a sign that a society is disintegrating when it takes its cues for manners and customs from the underclass. He describes such societies as being “truant” to their own values.

Toynbee is the guide to what we see all around us today.

We modern philistines tell ourselves that rejecting the customs and conventions of a stuffy, old elite will release creativity and bring about a renaissance. Nothing could be further from the truth. According to Toynbee, self-expression replaces creativity when disintegrating societies look downward.

Aspiration is replaced by complacency. Shame vanishes. Any criticism becomes “haters gonna hate,” or the White Trash motto: “It don’t make no difference.”

White Trash signifiers have changed of course — the foreclosed McMansion with the mosquito-infested swimming pool has replaced the rusting tractor permanently bivouacked on cement blocks in the front yard. But it’s the same general idea.

Obesity, the product of a lack of discipline, sloppy dressing, loud and intimate cellphone chats broadcast to a captive audience and foul language nonchalantly uttered in the ATM line are all forms of this “self-expression.”

Pre-White Trash, physical intimacy was reserved to private places. Now it’s reserved for the subway. You no longer have to live in a one-room shack to learn the facts of life early. Just walk down the toy aisle at Toys “R” Us for a sexpot Bratz Doll.

Children who see daytime television, broadcast in public areas, are inevitably treated to Jerry Springer reruns. How do you explain “Honey, I’m a Ho,” or “Transsexuals Attack” to a tot? Oh, wait, the tot explains it to you.

Tattoos are form of self-expression that have moved from gangs and prisons to the mainstream.

A 30-something scholar with a respected organization in Washington, DC, recently showed up at a fancy dinner in a little black cocktail dress, her shoulders extensively inked. Further sign of the impending apocalypse: She is a tattooed Chi Omega, once the Southern snob-appeal sorority. My young friend wore a “bespoke” tattoo, which means it was designed in consultation with an “artist.” In my mind, it bespoke volumes.

People in all walks of life used to put forth effort not to be taken for White Trash — in contrast to people today, who risk hepatitis to ape the decorative styles of prison gangs.

Not being White Trash wasn’t a matter of money. It was purely behavioral.

When did we decide that elastic waist bands, convict-inspired fashion and swearing on a cellphone were authentic ways to express individuality?

If we read our Toynbee, things may be even worse than we think. In Toynbee’s view, it’s up to the elites to save a civilization. They must become once again vigorously creative (think: great art, not twerking on TV) and worthy of imitation.

But how to get there from here? We could try saving our admiration for what’s really admirable. So let’s quit pretending that there’s anything charming about stripper-themed fashion and financial irresponsibility. All we have to lose is our inner Honey Boo Boo.

Bring back manners, bring back aspiration, bring back responsibility, heck, bring back the man in the gray flannel suit. We miss you.

The Writing Revolution

Wednesday, December 11th, 2013

The oddly named New Dorp High School underwent a writing revolution:

For decades, no one at New Dorp seemed to know how to help low-performing students like Monica, and unfortunately, this troubled population made up most of the school, which caters primarily to students from poor and working-class families. In 2006, 82 percent of freshmen entered the school reading below grade level. Students routinely scored poorly on the English and history Regents exams, a New York State graduation requirement: the essay questions were just too difficult. Many would simply write a sentence or two and shut the test booklet. In the spring of 2007, when administrators calculated graduation rates, they found that four out of 10 students who had started New Dorp as freshmen had dropped out, making it one of the 2,000 or so lowest-performing high schools in the nation. City officials, who had been closing comprehensive high schools all over New York and opening smaller, specialized ones in their stead, signaled that New Dorp was in the crosshairs.

And so the school’s principal, Deirdre DeAngelis, began a detailed investigation into why, ultimately, New Dorp’s students were failing. By 2008, she and her faculty had come to a singular answer: bad writing. Students’ inability to translate thoughts into coherent, well-argued sentences, paragraphs, and essays was severely impeding intellectual growth in many subjects. Consistently, one of the largest differences between failing and successful students was that only the latter could express their thoughts on the page. If nothing else, DeAngelis and her teachers decided, beginning in the fall of 2009, New Dorp students would learn to write well. “When they told me about the writing program,” Monica says, “well, I was skeptical.” With disarming candor, sharp-edged humor, and a shy smile, Monica occupies the middle ground between child and adult — she can be both naive and knowing. “On the other hand, it wasn’t like I had a choice. I go to high school. I figured I’d give it a try.”

New Dorp’s Writing Revolution, which placed an intense focus, across nearly every academic subject, on teaching the skills that underlie good analytical writing, was a dramatic departure from what most American students — especially low performers — are taught in high school. The program challenged long-held assumptions about the students and bitterly divided the staff. It also yielded extraordinary results. By the time they were sophomores, the students who had begun receiving the writing instruction as freshmen were already scoring higher on exams than any previous New Dorp class. Pass rates for the English Regents, for example, bounced from 67 percent in June 2009 to 89 percent in 2011; for the global-history exam, pass rates rose from 64 to 75 percent. The school reduced its Regents-repeater classes — cram courses designed to help struggling students collect a graduation requirement — from five classes of 35 students to two classes of 20 students.

The number of kids enrolling in a program that allows them to take college-level classes shot up from 148 students in 2006 to 412 students last year. Most important, although the makeup of the school has remained about the same — roughly 40 percent of students are poor, a third are Hispanic, and 12 percent are black — a greater proportion of students who enter as freshmen leave wearing a cap and gown. This spring, the graduation rate is expected to hit 80 percent, a staggering improvement over the 63 percent figure that prevailed before the Writing Revolution began. New Dorp, once the black sheep of the borough, is being held up as a model of successful school turnaround. “To be able to think critically and express that thinking, it’s where we are going,” says Dennis Walcott, New York City’s schools chancellor. “We are thrilled with what has happened there.”

In the coming months, the conversation about the importance of formal writing instruction and its place in a public-school curriculum — the conversation that was central to changing the culture at New Dorp — will spread throughout the nation. Over the next two school years, 46 states will align themselves with the Common Core State Standards. For the first time, elementary-school students — who today mostly learn writing by constructing personal narratives, memoirs, and small works of fiction — will be required to write informative and persuasive essays. By high school, students will be expected to produce mature and thoughtful essays, not just in English class but in history and science classes as well.

So, what writing skills were these kids learning?

What words, Scharff asked, did kids who wrote solid paragraphs use that the poor writers didn’t? Good essay writers, the history teacher noted, used coordinating conjunctions to link and expand on simple ideas — words like for, and, nor, but, or, yet, and so. Another teacher devised a quick quiz that required students to use those conjunctions. To the astonishment of the staff, she reported that a sizable group of students could not use those simple words effectively. The harder they looked, the teachers began to realize, the harder it was to determine whether the students were smart or not — the tools they had to express their thoughts were so limited that such a judgment was nearly impossible.

The exploration continued. One teacher noted that the best-written paragraphs contained complex sentences that relied on dependent clauses like although and despite, which signal a shifting idea within the same sentence. Curious, Fran Simmons devised a little test of her own. She asked her freshman English students to read Of Mice and Men and, using information from the novel, answer the following prompt in a single sentence:

“Although George …”

She was looking for a sentence like: Although George worked very hard, he could not attain the American Dream.

Some of Simmons’s students wrote a solid sentence, but many were stumped. More than a few wrote the following: “Although George and Lenny were friends.”

A lightbulb, says Simmons, went on in her head. These 14- and 15-year-olds didn’t know how to use some basic parts of speech. With such grammatical gaps, it was a wonder they learned as much as they did. “Yes, they could read simple sentences,” but works like the Gettysburg Address were beyond them — not because they were too lazy to look up words they didn’t know, but because “they were missing a crucial understanding of how language works. They didn’t understand that the key information in a sentence doesn’t always come at the beginning of that sentence.”

Some teachers wanted to know how this could happen. “We spent a lot of time wondering how our students had been taught,” said English teacher Stevie D’Arbanville. “How could they get passed along and end up in high school without understanding how to use the word although?”

But the truth is, the problems affecting New Dorp students are common to a large subset of students nationally.

That sounds like something straight from the Education Realist.

Four-winged robot flies like a jellyfish

Tuesday, December 10th, 2013

When you hear that a flying robot mimics an animal, you assume it’s a bird or an insect — or maybe a bat. How about a jellyfish?

A four-winged design created by Leif Ristroph and colleagues at New York University, which boasts a body plan reminiscent of a jellyfish, is more stable in the air than insect-like machines.

The prototype consists of a carbon-fibre frame surrounded by two pairs of thin plastic wings that open and close when driven by a motor. Its shape allows it to fly upright with little effort, without requiring sensors or intelligence to adjust its wings like those used by insects. “Making a dumb machine is a nice strategy for very small robots,” says Ristroph. “Without circuits and sensors, it’s also lighter.”

The robot is tethered to a power source for now, but improvements to the motor and wings should soon let it roam free.

How Memes Went Viral — In the 1800s

Tuesday, December 10th, 2013

The Infectious Texts project studies how memes went viral — in the 1800s:

The project expects to launch by the end of the month. When it does, researchers and the public will be able to comb through widely reprinted texts identified by mining 41,829 issues of 132 newspapers from the Library of Congress. While this first stage focuses on texts from before the Civil War, the project eventually will include the later 19th century and expand to include magazines and other publications, says Ryan Cordell, an assistant professor of English at Northeastern University and a leader of the project.

Some of the stories were printed in 50 or more newspapers, each with thousands to tens of thousands of subscribers. The most popular of them most likely were read by hundreds of thousands of people, Cordell says. Most have been completely forgotten. “Almost none of those are texts that scholars have studied, or even knew existed,” he said.

[...]

Some of the texts that went viral in the 1800s aren’t all that different from the things people post on Facebook today, Cordell says. Political rants were popular, for example, as were recipes and travel stories.

Poems also turn up frequently, as well as another type of writing Cordell calls vignettes. These are sentimental stories that are presented as if they’re real, but aren’t attributable to an author and lack details that would make it possible to verify them. One example is a letter, supposedly tucked into a book by a dying woman and found by her husband after her death. She urges him to remember her fondly and live a good life after she’s gone. “These are fascinating to me because they blur the line between fact and fiction, which sort of exemplifies the 19th century newspaper,” Cordell said.

The vignettes often had a moral to them. On popular variety, temperance stories, were aimed at getting drunks to sober up. Cordell likens these cautionary tales to the email you’ve probably gotten from a concerned aunt or uncle that turns out to be based on a bogus urban legend when you look it up on Snopes.

Taxing land would solve America’s biggest problems

Tuesday, December 10th, 2013

Jesse Myerson argues that taxing land would solve America’s biggest problems:

No need to tax labor and industry at all. Just tax the stuff that humans had nothing to do with creating, and therefore have no basis to claim ownership over at all. You’ll find that almost all of it is “owned” by the fabled 1 percent.

And boy are they sucking a lot of money out of it. By far the most valuable asset form in the U.S. is real estate, and the majority of that is the value of the land, as distinct from the value of the human-made buildings. Economist Michael Hudson has assessed that the land value of New York City alone exceeds that of all of the plant and equipment in the entire country, combined. No one put any enterprise or cost into producing the land’s value – they simply bought it when it was cheap, sold it when it was dear, and waited for the check. “They” are the Finance, Insurance and Real Estate (FIRE) sector, and they capture 40 percent of the United States’ profits, despite the complete passivity of their profit-accumulation method.

This is Henry George‘s single tax, which was too confiscatory for the right and not socialist enough for the left.

Print a Replica Glock Pistol

Monday, December 9th, 2013

A Russian blogger shares this photo of his 3D-printed replica Glock:

Glock Replica 3D Printed

A real Glock is part plastic — a different plastic — and part steel. I am surprised no one has printed a Glock frame and mated it with steel parts yet. Or have I simply missed it?

Storm From A Clear Sky

Monday, December 9th, 2013

We often hear about Nazi super-weapons — there was a whole cable channel dedicated to Hitler, wasn’t there? — but the Japanese had submarine aircraft carriers by the end of the war:

The I-400 subs were the largest ever built until the Ethan Allen-class of nuclear subs in 1961. The I-400 subs not only could travel one and a half times around the world without refueling, they carried three Aichi M6A1 attack planes, which they launched off their bow when surfaced, effectively making them underwater aircraft carriers.

Soon after the war, the US Navy sank the captured super-subs, to test its new top-secret “robot” torpedo — but really to keep them out of our supposed Allies’ hands:

I-400 Sinking to Foil Russians

The Hawaii Undersea Research Laboratory, or HURL, has found the rusting hulks off the coast of Oahu.

Now all they need is a little clean-up and a Wave Motion Engine

Will the Real Satoshi Nakamoto Please Stand Up?

Monday, December 9th, 2013

Wait, Satoshi Nakamoto, founder of Bitcoin, might be Nick Szabo?

I recently became interested in identifying the pseudonymous creator of Bitcoin, Satoshi Nakamoto. I started from the Bitcoin whitepaper [0] published in late 2008, and proceeded to run reverse textual analysis –essentially, searching the internet for highly unusual turns of phrase and vocabulary patterns (in particular places which you would expect a cryptography researcher to contribute to), then evaluating the fitness of each match found by running textual similarity metrics on several pages of their writing.

Which led me rather directly to several articles from Nick Szabo’s blog.

For those who wouldn’t know Nick Szabo and his documented links to Bitcoin: prior to the apparition of Bitcoin, Nick had been developing for several years (since 1998 [1]) the enabling mechanism for a decentralized digital currency, eventually converging on a system he called “bit gold” [3], which is the direct precursor to the Bitcoin architecture.

According to what seems to be a widely accepted origin story of Bitcoin, Satoshi Nakamoto was a highly skilled computer scientist (or group thereof) who found about Nick’s proposition for bit gold, hit upon an idea for bettering it, published the Bitcoin whitepaper, and decided to turn it into reality by developing the original Bitcoin client. Nick denies being Satoshi, and has stated his official opinion on Satoshi and Bitcoin in a May 2011 article [1].

I would argue that Satoshi is actually Nick Szabo himself, probably together with one or more technical collaborators.

As I mention above, what originally led me to this hypothesis is that reverse-searching for content similar to the Bitcoin whitepaper led me to Nick’s blog, completely independently of any knowledge of the official Bitcoin story. I must stress this: an open, unbiased search of texts similar in writing to the Bitcoin whitepaper over the entire Internet, identifies Nick’s bit gold articles as the best candidates. It could still be a coincidence, although an unlikely one — since cryptocurrencies were a fairly niche topic in 2008 and earlier (seemingly 3 or 4 people), every contributor to the field was going to be reusing the same shared expressions and vocabulary. Satoshi would have been a reader of Nick’s blog, so you would expect him to describe the same concepts in a similar way. But there’s more.

Running similarity metrics on the whitepaper and Nick’s bit gold articles as well as his paper “formalizing and securing relationships on public networks” [2] indicated an excellent match over content-neutral expressions as well — so either Nick wrote the whitepaper, or it was written by somebody imitating Nick’s writing style.

TechCrunch interviews Skye Grey:

I am not certain it’s Nick Szabo, but I have quite a few independent pieces of evidence pointing in his direction, each one interesting in itself:

  • text analysis (only 0.1% of cryptography researchers could have produced this writing style –again, please, attack my methods on this)
  • fact that Nick was searching for technical collaborators on the bit gold project (a very similar cryptocurrency) a few months before the announcement of Bitcoin (and then the bit gold project became perfectly silent)
  • lack of citation of Nick’s work by Satoshi, whereas he cited other, less related cryptocurrencies
  • lack of reaction on Nick’s part about Bitcoin, whereas a decentralized currency like Bitcoin had been a major project of his for 10 years
  • fact that Nick deliberately post-dated his bit gold articles to look posterior to Bitcoin, shortly after the announcement of Bitcoin

Galactic Patrol

Monday, December 9th, 2013

E.E. “Doc” Smith’s Galactic Patrol comes as close to an immortal classic as a bit of juvenile pulp space opera can ever come, John C. Wright says:

I rate Smith in SF on the same level as Jack Kirby in comics: he is the king of a humble country, but still it is a thing passing brave to be a king.

[...]

Nowadays, it is more likely that an SF fan cannot read this work without being reminded of the later works copying it (STAR WARS is the most obvious example) and the fan will most likely be more familiar with the copies than the original, and regard the original, ironically, as derivative.

When I was a kid, desperate for a rumor about Revenge of the Jedi — it was still Revenge then, not Return — I remember hearing that it would feature an even bigger Death Star.

This is the kind of thing E.E. “Doc” Smith did all the time. Each book in the Lensman series introduces an enemy ten times as powerful as the last:

Each book is so cleverly constructed that it can be read independently, coming to what seems a perfectly satisfying conclusion with no loose ends, but in the first chapter of the next book the reader discovers that things are not what they seemed, and that the big evil black hat of the last book was himself but an agent of a higher, deeper, darker power from a race even farther away with even more psionic powers. This Russian Doll approach to writing sequels has been rarely tried, and this is the sole successful example of how to do it known to this writer.

It is a hard trick to pull off, and, as far as I know, Smith is the first author ever to attempt it. Each volume has to be completely satisfying in and of itself, with no dangling ends or odd mysteries left over (something Smith complained Edgar Rice Burroughs was guilty of–see GODS OF MARS for an obvious example), but also has to be open ended enough to smoothly mesh with the bigger picture once the curtains are drawn back even farther so that what you thought was the head of the dragon our hero just slew turns out to be one head of the Hydra, who turns out to have brothers bent on revenge, who turns out to have been sent out by some immortal from the underworld.

I am hard pressed to think of an example of such a thing being done once, much less four times in a row.

When “Doc” was writing, cars had just made fast getaways a powerful criminal tool:

[T]the very first scene of the first chapter establishes the science fictional speculation which is the core of the series, namely, what would be the effect of fast and cheap interstellar travel on society, specifically, on crime rates?

Organized crime, particularly acts of piracy, would be unstoppable: any wrongdoer on any world in the galaxy could flit to any other, commit robberies and slave-taking and mayhem, and be outside the range of local, continental, worldwide and system wide authorities faster than a radio wave (which moseys along at lightspeed) could spread the alarm. The impossibility of tracking a fleeing criminal in a space vessel is literally astronomical. If the fugitive goes to ground on a foreign world, inhabited by aliens whose language the pursuing police officer does not speak, whose customs he does not understand, and whose atmosphere he cannot breathe, the problem is even worse. If in addition, previous contact has been rare or none, the police officer also has the problem of identifying which shiny bent thing with leaves is the leader of the political organization, if any, the aliens possess, as opposed to which is the houseplant. More to the point for this story, the alien has the problem of discovering which of the two Earthmen just landed on his world is the police officer and which is the crook.

Obviously the scope of this problem depends on myriad factors, such as the frequency of alien contacts or the number of alien races, the speed of the ships, the ease of communication, the ease with which new territory can be discovered, and so on. But the international policing mechanisms and treaties used just here on Earth, if Earth were a ringworld or Dyson’s sphere and therefore had within sailing range a hundred continents instead of seven, or thousands, and a sailing ship could quickly reach destinations millions of miles away, all such treaties would be woefully inadequate. The solutions to organized crime on an interstellar scale do not ‘scale up’.

The answer in the Lensman universe is that a coldly superior race, called the Arisians, for reasons not revealed in the first volume, has granted to civilization a lens-shaped semi-living gem (or organism or device or thought-construct) which cannot be counterfeited, which cannot be used by anyone save the one soul to whom it has been attuned, and further kills anyone attempting to don it except the true owner. It is a badge that cannot be counterfeited. The Lens also acts as a telepathic sender and receiver and universal translator.

And, just to make things easy, the superior beings can identify beforehand who has the moral stature needed never to abuse the immense power of the lens, so no one but the Worthiest of the Worthy ever is given this badge of office. So the lens allows the police officer instantly to identify himself to any living intelligence on any world, telepathically display his good intentions and the honesty of his purpose, and understand any form of communication.

Unrealistic? Sure, but not any more so than the idea of Faster Than Light drive itself, or intelligent life on other planets.

The Lensman stories are the source of a ridiculous number of scif-fi tropes — including the Big Board, which became a real thing.

How a Radical New Teaching Method Could Unleash a Generation of Geniuses

Sunday, December 8th, 2013

With standard hyperbole, Joshua Davis describes how a radical new teaching method could unleash a generation of geniuses:

In 1999, Sugata Mitra was chief scientist at a company in New Delhi that trains software developers. His office was on the edge of a slum, and on a hunch one day, he decided to put a computer into a nook in a wall separating his building from the slum. He was curious to see what the kids would do, particularly if he said nothing. He simply powered the computer on and watched from a distance. To his surprise, the children quickly figured out how to use the machine.

Over the years, Mitra got more ambitious. For a study published in 2010, he loaded a computer with molecular biology materials and set it up in Kalikuppam, a village in southern India. He selected a small group of 10- to 14-year-olds and told them there was some interesting stuff on the computer, and might they take a look? Then he applied his new pedagogical method: He said no more and left.

Over the next 75 days, the children worked out how to use the computer and began to learn. When Mitra returned, he administered a written test on molecular biology. The kids answered about one in four questions correctly. After another 75 days, with the encouragement of a friendly local, they were getting every other question right. “If you put a computer in front of children and remove all other adult restrictions, they will self-organize around it,” Mitra says, “like bees around a flower.”

A charismatic and convincing proselytizer, Mitra has become a darling in the tech world. In early 2013 he won a $1 million grant from TED, the global ideas conference, to pursue his work. He’s now in the process of establishing seven “schools in the cloud,” five in India and two in the UK. In India, most of his schools are single-room buildings. There will be no teachers, curriculum, or separation into age groups — just six or so computers and a woman to look after the kids’ safety. His defining principle: “The children are completely in charge.”

Mitra argues that the information revolution has enabled a style of learning that wasn’t possible before. The exterior of his schools will be mostly glass, so outsiders can peer in. Inside, students will gather in groups around computers and research topics that interest them. He has also recruited a group of retired British teachers who will appear occasionally on large wall screens via Skype, encouraging students to investigate their ideas — a process Mitra believes best fosters learning. He calls them the Granny Cloud. “They’ll be life-size, on two walls” Mitra says. “And the children can always turn them off.”

Mitra’s work has roots in educational practices dating back to Socrates. Theorists from Johann Heinrich Pestalozzi to Jean Piaget and Maria Montessori have argued that students should learn by playing and following their curiosity. Einstein spent a year at a Pestalozzi-inspired school in the mid-1890s, and he later credited it with giving him the freedom to begin his first thought experiments on the theory of relativity. Google founders Larry Page and Sergey Brin similarly claim that their Montessori schooling imbued them with a spirit of independence and creativity.

In recent years, researchers have begun backing up those theories with evidence. In a 2011 study, scientists at the University of Illinois at Urbana-Champaign and the University of Iowa scanned the brain activity of 16 people sitting in front of a computer screen. The screen was blurred out except for a small, movable square through which subjects could glimpse objects laid out on a grid. Half the time, the subjects controlled the square window, allowing them to determine the pace at which they examined the objects; the rest of the time, they watched a replay of someone else moving the window. The study found that when the subjects controlled their own observations, they exhibited more coordination between the hippocampus and other parts of the brain involved in learning and posted a 23 percent improvement in their ability to remember objects. “The bottom line is, if you’re not the one who’s controlling your learning, you’re not going to learn as well,” says lead researcher Joel Voss, now a neuroscientist at Northwestern University.

In 2009, scientists from the University of Louisville and MIT’s Department of Brain and Cognitive Sciences conducted a study of 48 children between the ages of 3 and 6. The kids were presented with a toy that could squeak, play notes, and reflect images, among other things. For one set of children, a researcher demonstrated a single attribute and then let them play with the toy. Another set of students was given no information about the toy. This group played longer and discovered an average of six attributes of the toy; the group that was told what to do discovered only about four. A similar study at UC Berkeley demonstrated that kids given no instruction were much more likely to come up with novel solutions to a problem. “The science is brand-new, but it’s not as if people didn’t have this intuition before,” says coauthor Alison Gopnik, a professor of psychology at UC Berkeley.

Gopnik’s research is informed in part by advances in artificial intelligence. If you program a robot’s every movement, she says, it can’t adapt to anything unexpected. But when scientists build machines that are programmed to try a variety of motions and learn from mistakes, the robots become far more adaptable and skilled. The same principle applies to children, she says.

Evolutionary psychologists have also begun exploring this way of thinking. Peter Gray, a research professor at Boston College who studies children’s natural ways of learning, argues that human cognitive machinery is fundamentally incompatible with conventional schooling. Gray points out that young children, motivated by curiosity and playfulness, teach themselves a tremendous amount about the world. And yet when they reach school age, we supplant that innate drive to learn with an imposed curriculum. “We’re teaching the child that his questions don’t matter, that what matters are the questions of the curriculum. That’s just not the way natural selection designed us to learn. It designed us to solve problems and figure things out that are part of our real lives.”

Some school systems have begun to adapt to this new philosophy — with outsize results. In the 1990s, Finland pared the country’s elementary math curriculum from about 25 pages to four, reduced the school day by an hour, and focused on independence and active learning. By 2003, Finnish students had climbed from the lower rungs of international performance rankings to first place among developed nations.

Nicholas Negroponte, cofounder of the MIT Media Lab, is taking this approach even further with his One Laptop per Child initiative. Last year the organization delivered 40 tablets to children in two remote villages in Ethiopia. Negroponte’s team didn’t explain how the devices work or even open the boxes. Nonetheless, the children soon learned to play back the alphabet song and taught themselves to write letters. They also figured out how to use the tablet’s camera. This was impressive because the organization had disabled camera usage. “They hacked Android,” Negroponte says.

The Darker, Creepier Crystal

Saturday, December 7th, 2013

I remember The Dark Crystal as fairly dark and creepy, but apparently the final version wasn’t as dark and creepy as Jim Henson and Frank Oz originally intended. Now an obsessed fan’s own edit restores the darkness and the creepiness:

The earlier cut didn’t test well with audiences, so the film was substantially changed to appeal to a broad audience. Voiceover was added, and English dialogue was added to many scenes where the action was previously supposed to be understood through puppets’ pantomime.

For the past two years an enterprising fan, 31-year-old Christopher Orgeron, has labored to reassemble that original cut of the movie. He had limited materials to work with, so there are rough edges in many places (most notably the black-and-white scenes from a VHS dub of the original cut).

Why Isn’t Open Source A Gateway For Coders Of Color?

Saturday, December 7th, 2013

Why isn’t open source a gateway for coders of color?, NPR naively asks:

You don’t have to know somebody or have a degree in software engineering or get hired to participate in an open-source project. You can jump right in and start writing some code.

[...]

But in Haibel’s experience, the open-source world is even whiter and more male than the world of proprietary software. “It’s very clear that the open source community is whiter than the software community as a whole,” she says.

Which is to say: pretty darn white. According to a report from the Bureau of Labor Statistics, more than eight in 10 software developers in 2012 were white. We should note that while white developers were overrepresented, so were Asian-Americans. So it’s not like people of color are not in software development; but blacks and Latinos are significantly underrepresented.

Commenter Ross notes that the “article presents the usual slurry,” but the “comments are faintly heartening,” like this one:

Excuses, excuses, excuses. That is all I see.

I am black. I consider myself a rookie software developer. I focus mostly on mobile computing. I did not attend a higher learning institution to study computer science. Three quarters of my computer skills come from just “messing around” trying to do whatever I want to do at the time. I use superuser and stackoverflow extensively.

There are only 24 hours in a day so we make time for what we care about. My peers spend their free time going to night clubs, watching useless television shows, and chasing endless fashion trends. They only consume. They are the quintessential example of what it is to be a consumer. They are the people that companies aim to have as customers. Many of them have skills but neglect to even attempt to put their skills to work. And when you ask them why, all they have for you is excuses. My race this, my gender that. We are living in an age when it is easier than ever before in human history to use your skills and ideas to positively impact your world. There are a multitude of projects going on around even just in the United States that are audacious and are chocked full of ambition. It amazes me that even with all the curious and indispensable tools of today some people miraculously still feel disenfranchised and dejected. In some cases I have gone as far as telling people EXACTLY what they should do to get started. They did not have to think. They only had to act, and shed their fear of their own potential yet even this was a step too far away from the comfort zone. After considering my experiences, I come to the conclusion that it is perhaps not so ridiculous that the world’s richest 1% owns the vast majority of wealth on the planet.

You cannot free a man’s mind. He must free himself.

Britain’s Allies in the Mediterranean

Japanese destroyers Sakaki and Matsu, docked in Malta, 1918In August of 1917, Admiral George A. Ballard, Senior Naval Officer-in-Charge at Malta, reported to the Admiralty that the Japanese had rendered invaluable service in escorting troop transports since their arrival at Malta:

French standards of efficiency are certainly lower than British, however, and Italian standards are lower still. With the Japanese it is otherwise. Admiral Sato’s destroyers are kept in a highly serviceable condition and spend at least as large a proportion of their time at sea as our own, which is far from being the case with the French and Italian vessels of any class. The Japanese moreover are very independent in all matters of administration and supply whereas the French will never do anything for themselves if they can get it done for them.
