Familiar strangers

commonplace book, science, social software / /

From danah boyd’s “G/localization: When Global Information and Local Interaction Collide“:

In the early 1970s, Stanley Milgram was intrigued by what he called “familiar strangers” – people who recognized each other in public life but never interacted. Through experiments, he found that people are most likely to interact with people when removed from the situation in which they are familiarly strangers. In other words, two people who take the same bus every day for years may never interact, but if they were to run into each other in a different environment across town, they would say hello and talk about the bus. If they run into each other in a foreign country, they will immediately be close friends.

Religion & evolution

religion, science / /

From Salon’s “Religious belief itself is an adaptation“, an interview with Edward O. Wilson:

Religious belief itself is an adaptation that has evolved because we’re hard-wired to form tribalistic religions. Religion is intensely tribalistic. A devout Christian or Muslim doesn’t say one religion is as good as another. It gives them faith in the particular group to which they belong and that set of beliefs and moral views. …

You cannot explain the patterns of diversity in the world, the geography of life, the endless details of distribution, similarity and dissimilarity in the world, by any means except evolution. That’s the one theory that ties it together. It is very hard to see how traditionalist religious views will come to explain the meaning of life on this planet. …

Bertrand Russell on writing well

From Bertrand Russell’s “How I Write“:

Until I was twenty-one, I wished to write more or less in the style of John Stuart Mill. … I had, however, already a different ideal, derived, I suppose, from mathematics. I wished to say everything in the smallest number of words in which it could be said clearly. … I would spend hours trying to find the shortest way of saying something without ambiguity, and to this aim I was willing to sacrifice all attempts at aesthetic excellence.

At the age of twenty-one, however, I came under a new influence that of my future brother-in-law, Logan Pearsall Smith. He was at that time exclusively interested in style as opposed to matter. His gods were Flaubert and Walter Pater, and I was quite ready to believe that the way to learn how to write was to copy their technique. He gave me various simple rules, of which 1 remember only two: “Put a comma every four words”, and “never use ‘and’ except at the beginning of a sentence”. His most emphatic advice was that one must always re-write. I conscientiously tried this, but found that my first draft was almost always better than my second. This discovery has saved me an immense amount of time. I do not, of course, apply it to the substance, but only to the form. When I discover an error of an important kind I re-write the whole. What I do not find is that I can improve a sentence when I am satisfied with what it means.

… In fact, all imitation is dangerous. Nothing could be better in style than the Prayer Book and the Authorized Version of the Bible, but they express a way of thinking and feeling which is different from that of our time. A style is not good unless it is an intimate and almost involuntary expression of the personality of the writer, and then only if the writer’s personality is worth expressing. But although direct imitation is always to be deprecated, there is much to be gained by familiarity with good prose, especially in cultivating a sense for prose rhythm.

There are some simple maxims-not perhaps quite so simple as those which my brother-in-law Logan Pearsall Smith offered me-which I think might be commanded to writers of expository prose. First: never use a long word if a short word will do. Second: if you want to make a statement with a great many qualifications, put some of the qualifications in separate sentences. Third: do not let the beginning of your sentence lead the reader to an expectation which is contradicted by the end.

Water that uniquely identifies its owner

science, security, writing ideas / /

From SmartWater Technology:

SmartWater Security Systems are forensic coding systems which can be applied in several ways:

SmartWater Tracer

An aqueous based solution with a unique forensic code.

SmartWater Tracer uniquely codes your property, whilst being virtually invisible to the naked eye, glows under UV light and is practically impossible to remove entirely. Tracer is used in commercial businesses, schools, hospitals and other organisations. Tracer is also used in our Home Coding System so that you can use it safely on jewellery and other sentimental items.

SmartWater Instant

Forensic Coding combined with microdot technology.

SmartWater has been designed to protect household property and motor vehicles. Each bottle of SmartWater solution contains a unique forensic code, which is assigned to a household or vehicle.

An additional feature of SmartWater Instant is the inclusion of tiny micro-dot particles which enable Police to quickly identify the true owner of the property.

SmartWater SuperLabel

Forensic Coding is embedded into the adhesive of tamper resistant labels – combines effective asset management with the protection of Tracer.

The SuperLabel is designed to be tamper resistant making it extremely difficult to remove. Should the label be removed, ownership of the asset can be established from the smallest speck of adhesive, as it contains the forensic code. As with the other SmartWater products this is also designed to glow under Ultra Violet light. Your company logo can also be incorporated into the adhesive, providing quick identification of the true owner of the property.

How to fake an anthrax scare

science, security, writing ideas / /

From Bruce Schneier’s “White Powder Anthrax Hoaxes“:

Earlier this month, there was an anthrax scare at the Indonesian embassy in Australia. Someone sent them some white powder in an envelope, which was scary enough. Then it tested positive for bacillus. The building was decontaminated, and the staff was quarantined for twelve hours. By then, tests came back negative for anthrax.

A lot of thought went into this false alarm. The attackers obviously knew that their white powder would be quickly tested for the presence of a bacterium of the bacillus family (of which anthrax is a member), but that the bacillus would have to be cultured for a couple of days before a more exact identification could be made. So even without any anthrax, they managed to cause two days of terror.

… In an interesting side note, the media have revealed for the first time that 360 “white powder” incidents have taken place since 11 September 2001. This news had been suppressed by the government, which had issued D notices to the media for all such incidents. So there has been one such incident approximately every four days — an astonishing number, given Australia’s otherwise low crime rate.

Four principles of modernity

commonplace book, science / /

From “Relativity, Uncertainty, Incompleteness and Undecidability“:

In this article four fundamental principles are presented: relativity, uncertainty, incompleteness and undecidability. They were studied by, respectively, Albert Einstein, Werner Heisenberg, Kurt Gödel and Alan Turing. …

Relativity says that there is no privileged, “objective” viewpoint for certain observations. … Now, if things move relative to each other, then obviously their positions at a given time are also measured relative to each other. …

Werner Heisenberg showed that if we built a machine to tell us with high precision were an electron is, this machine could not also tell us the speed of the electron. If we want to measure its speed without altering it we can use a different light but then we wouldn’t know where it is. At atomic scale, no instrument can tell us at the same time exactly where a particle is and exactly at what speed it is moving. …

If this system is complete, then anything that is true is provable. Similarly, anything false is provable false. Kurt Gödel got the intuition that traditional mathematical logic was not complete, and devoted several years to try to find one thing, a single thing that was inside the mathematics but outside the reach of logic. … Gödel’s incompleteness means that the classical mathematical logic deductive system, and actually any logical system consistent and expressive enough, is not complete, has “holes” full of expressions that are not logically true nor false. …

Turing’s halting problem is one of the problems that fall in to the category of undecidable problems. It says that it is not possible to write a program to decide if other program is correctly written, in the sense that it will never hang. This creates a limit to the verification of all programs, as all the attempts of building actual computers, usable in practice and different from Turing machines have been proved to be equivalent in power and limitations to the basic Turing machine.

Funes the Memorious, for real

From “New form of superior memory syndrome found“:

Scientists at the University of California-Irvine have identified the first known case of a new, superior memory syndrome.

Researchers Elizabeth Parker, Larry Cahill and James McGaugh spent more than five years studying the case of “AJ,” a 40-year-old woman with incredibly strong memories of her personal past.

Given a date, AJ can recall with astonishing accuracy what she was doing on that date and what day of the week it was. Because her case is the first of its kind, the researchers have proposed a name for her syndrome — hyperthymestic syndrome — based on the Greek word thymesis for “remembering” and hyper, meaning “more than normal.” …

“What makes this young woman so remarkable is that she uses no mnemonic devices to help her remember things,” said McGaugh.

The incompetent don’t know it

commonplace book, science / /

From “Unskilled and Unaware of It“:

It seems that the reason for this phenomenon is obvious: The more incompetent someone is in a particular area, the less qualified that person is to assess anyone’s skill in that space, including their own. When one fails to recognize that he or she has performed poorly, the individual is left assuming that they have performed well. As a result, the incompetent will tend to grossly overestimate their skills and abilities. A few years ago, two men from the Department of Psychology at Cornell University made an effort to determine just how profoundly one misoverestimates one’s own skills in relation to one’s actual abilities. They made four predictions, and executed four studies.

Justin Kruger and David Dunning made the following predictions before beginning their investigation:

  • Incompetent individuals, compared with their more competent peers, will dramatically overestimate their ability and performance relative to objective criteria.
  • Incompetent individuals will suffer from deficient metacognitive skills, in that they will be less able than their more competent peers to recognize competence when they see it–be it their own or anyone else’s.
  • Incompetent individuals will be less able than their more competent peers to gain insight into their true level of performance by means of social comparison information. In particular, because of their difficulty recognizing competence in others, incompetent individuals will be unable to use information about the choices and performances of others to form more accurate impressions of their own ability.
  • The incompetent can gain insight about their shortcomings, but this comes (paradoxically) by making them more competent, thus providing them the metacognitive skills necessary to be able to realize that they have performed poorly.

… In short, the study showed that the researchers’ predictions were spot-on. …

Also interestingly, the top performers tended to underestimate their own performance compared to their peers. The researchers found that those participants fell prey to the false-consensus effect, a phenomenon where one assumes that one’s peers are performing at least as well as oneself when given no evidence to the contrary.

Pi to unfathomable places

cool stuff, science / /

From “Man recites pi from memory to 83,431 places“:

A Japanese psychiatric counselor has recited pi to 83,431 decimal places from memory, breaking his own personal best of 54,000 digits and setting an unofficial world record, a media report said Saturday.

Akira Haraguchi, 59, had begun his attempt to recall the value of pi – a mathematical value that has an infinite number of decimal places – at a public hall in Chiba city, east of Tokyo, on Friday morning and appeared to give up by noon after only reaching 16,000 decimal places, the Tokyo Shimbun said on its Web site.

But a determined Haraguchi started anew and had broken his old record on Friday evening, about 11 hours after first sitting down to his task, the paper said. …

Pi, usually given as an abbreviated 3.14, is the ratio of the circumference to the diameter of a circle. The number has fascinated and confounded mathematicians for centuries.

Aided by a supercomputer, a University of Tokyo mathematician set the world record for figuring out pi to 1.24 trillion decimal places in 2002.

Did plague cause the Little Ice Age?

history, science / /

From BBC News’ “Europe’s chill linked to disease“:

Europe’s “Little Ice Age” may have been triggered by the 14th Century Black Death plague, according to a new study.

Pollen and leaf data support the idea that millions of trees sprang up on abandoned farmland, soaking up carbon dioxide from the atmosphere.

This would have had the effect of cooling the climate, a team from Utrecht University, Netherlands, says.

The Little Ice Age was a period of some 300 years when Europe experienced a dip in average temperatures. …

“Between AD 1200 to 1300, we see a decrease in stomata and a sharp rise in atmospheric carbon dioxide, due to deforestation we think,” says Dr van Hoof, whose findings are published in the journal Palaeogeography, Palaeoclimatology, Palaeoecology.

But after AD 1350, the team found the pattern reversed, suggesting that atmospheric carbon dioxide fell, perhaps due to reforestation following the plague.

The researchers think that this drop in carbon dioxide levels could help to explain a cooling in the climate over the following centuries.

Sixty-four-year-old Thai Ngoc, known as Hai Ngoc, said he could not sleep at night after getting a fever in 1973, and has counted infinite numbers of sheep during more than 11,700 consecutive sleepless nights.

“I don’t know whether the insomnia has impacted my health or not. But I’m still healthy and can farm normally like others,” Ngoc said. …

Ngoc often does extra farm work or guards his farm at night to prevent theft, saying he used three months of sleepless nights to dig two large ponds to raise fish.

Neighbor Vu said Ngoc volunteered to help beat a drum during the night and guard the house for the relatives of the dead during funeral ceremonies so that they could take a nap.

The last remaining Stone Age tribesmen

commonplace book, science, true stories / /

From “Stone Age tribe kills fishermen“:

ONE of the world’s last Stone Age tribes has murdered two fishermen whose boat drifted on to a desert island in the Indian Ocean.

The Sentinelese, thought to number between 50 and 200, have rebuffed all contact with the modern world, firing a shower of arrows at anyone who comes within range.

They are believed to be the last pre-Neolithic tribe in the world to remain isolated and appear to have survived the 2004 Asian tsunami. …

Fellow fishermen said they dropped anchor for the night on January 25 but fell into a deep sleep, probably helped by large amounts of alcohol. During the night their anchor, a rock tied to a rope, failed to hold their open-topped boat against the currents and they drifted towards the island.

“As day broke, fellow fishermen say they tried to shout at the men and warn them they were in danger,” said Samir Acharya, the head of the Society for Andaman and Nicobar Ecology, an environmental organisation. “However they did not respond – they were probably drunk – and the boat drifted into the shallows where they were attacked and killed.”

The Indian coast guard tried to recover the bodies using a helicopter but was met by a hail of arrows.

Photographs shot from the helicopter show the near-naked tribesmen rushing to fire. But the downdraught from its rotors exposed the two fishermen buried in shallow graves and not roasted and eaten, as local rumour suggested. …

Environmental groups urged the authorities to leave the bodies and respect the five-kilometre exclusion zone thrown around the island. In the 1980s and early 1990s many Sentinelese were killed in skirmishes with armed salvage operators who visited the island after a shipwreck. Since then the tribesmen have remained virtually undisturbed.

Why can’t we remember our early childhoods?

commonplace book, science / /

From Dave Munger’s “Why do we forget our childhood?“:

… [Freud] did discover an important phenomenon which continues to be investigated today. Freud noted that adults do not remember childhood events occurring before they were as old as six. This period of childhood amnesia is now generally believed to end at about age three or four. Though current psychologists don’t put much stock in Freud’s explanation of the phenomenon (he believed the memories were repressed because they are too traumatic), there is still little agreement on what causes it.

Gabrielle Simcock and Harlene Hayne of the University of Otago noticed that the period of amnesia tends to end at about the time of the onset of language, so they devised an experiment to test whether language ability might be at the root of the problem (“Breaking the Barrier? Children Fail to Translate Their Preverbal Memories Into Language,” Psychological Science, 2002).

They created a memorable event for toddlers of ages ranging from two to three: a magical shrinking machine. …

Six months to a year later, the toddlers were revisited and asked about the experience. Most kids, regardless of their age, could say very little about the shrinking machine. However, when they were shown photos of the toys from the experiment along with decoys (for example, four teddy bears, only one of which was used in the game), they accurately identified the toys from the game most of the time. … The memory existed, but the words were not associated with the memory.

Simcock and Hayne argue that these memories simply are not ever encoded in language, and for that reason, never become part of an adult’s autobiographical memory.

What would it be like to feel no pain?

science, weird / /

From CNN’s “World without pain is hell, parent says“:

Roberto is one of 17 people in the United States with “congenital insensitivity to pain with anhidrosis,” referred to as CIPA by the few people who know about it. …

Other abnormalities quickly surfaced. Roberto was severely susceptible to heatstroke on hot summer days. His parents soon noticed he did not sweat.

“You can’t carry Roberto because he sucks your heat from your body. You’re hot, sweaty. His body can’t sweat like yours so he’s just absorbing all of your heat,” Stingley-Salazar said.

His family was shocked when Roberto started teething. He gnawed on his own tongue, lips and fingers to the point of mutilation. …

Axelrod has studied this family of “no-pain” diseases for more than 35 years. These genetic disorders affect the autonomic nervous system — which controls blood pressure, heart rate, sweating, the sensory nerve system and the ability to feel pain and temperature. …

CIPA is the most severe and fatal type of the seven types of hereditary sensory and autonomic neuropathy, or HSAN. Overheating kills more than half of all children with CIPA before age 3, Stingley-Salazar said.

According to Axelrod, levels of pain vary.

“For some children it’s a mild degree such as breaking a leg, they’ll get up and walk on the leg. They feel that something is uncomfortable but they keep on moving,” she said. “For other children, the pain loss is so severe that they can injure themselves repetitively and actually mutilate themselves because they don’t know when to stop.”

All HSAN disorders are recessive genetic disorders — both parents have to carry the genetic mutation in order to pass it on to a child. But there is less than a 1-in-4 chance that the child will develop it. …

A more common HSAN condition is familial dysautonomia, or FD. There are about 500 cases of FD in the United States, Axelrod said.

The first sign of FD is a child’s inability to suck properly followed by delayed milestones — these children walk and speak later.

Often, FD patients endure severely dry eyes because they are unable to produce tears.

Also, part of this sensory disorder is difficulty “telling where they are in space,” Axelrod said.

The minor effect is constantly bumping into things. The major effect is that 80 percent of these kids suffer curvature of the spine because they have no concept of posture.

Forced to commit suicide by brain parasites

From New Scientist‘s “Parasites brainwash grasshoppers into death dive“:

A parasitic worm that makes the grasshopper it invades jump into water and commit suicide does so by chemically influencing its brain, a study of the insects’ proteins reveal.

The parasitic Nematomorph hairworm (Spinochordodes tellinii) develops inside land-dwelling grasshoppers and crickets until the time comes for the worm to transform into an aquatic adult. Somehow mature hairworms brainwash their hosts into behaving in way they never usually would – causing them to seek out and plunge into water.

Once in the water the mature hairworms – which are three to four times longer that their hosts when extended – emerge and swim away to find a mate, leaving their host dead or dying in the water. …

Now Biron and his colleagues have shown that the worm brainwashes the grasshopper by producing proteins which directly and indirectly affect the grasshopper’s central nervous system.

Night terrors

science, weird / /

From Science News’ “Night of the Crusher: The waking nightmare of sleep paralysis propels people into a spirit world“:

As a college student in 1964, David J. Hufford met the dreaded Night Crusher. Exhausted from a bout of mononucleosis and studying for finals, Hufford retreated one December day to his rented, off-campus room and fell into a deep sleep. An hour later, he awoke with a start to the sound of the bedroom door creaking open—the same door he had locked and bolted before going to bed. Hufford then heard footsteps moving toward his bed and felt an evil presence. Terror gripped the young man, who couldn’t move a muscle, his eyes plastered open in fright.

Without warning, the malevolent entity, whatever it was, jumped onto Hufford’s chest. An oppressive weight compressed his rib cage. Breathing became difficult, and Hufford felt a pair of hands encircle his neck and start to squeeze. “I thought I was going to die,” he says.

At that point, the lock on Hufford’s muscles gave way. He bolted up and sprinted several blocks to take shelter in the student union. “It was very puzzling,” he recalls with a strained chuckle, “but I told nobody about what happened.”

Hufford’s perspective on his strange encounter was transformed in 1971. He was at that time a young anthropologist studying folklore in Newfoundland, and he heard from some of the region’s inhabitants about their eerily similar nighttime encounters. Locals called the threatening entity the “old hag.” Most cases unfold as follows: A person wakes up paralyzed and perceives an evil presence. A hag or witch then climbs on top of the petrified victim, creating a crushing sensation on his or her chest.

It took Hufford another year to establish that what he and these people of Newfoundland had experienced corresponds to the event, lasting seconds or minutes, that sleep researchers call sleep paralysis. …

Sleep paralysis differs from nocturnal panic, in which a person awakens in terror with no memory of a dream. Neither does sleep paralysis resemble a night terror, in which a person suddenly emerges from slumber in apparent fear, flailing and shouting, but then falls back asleep and doesn’t recall the incident in the morning.

Curiously, although the word nightmare originally described sleep paralysis, it now refers to a fearful or disturbing dream, says Hufford, now at the Penn State Medical Center in Hershey, Pa. Several hundred years ago, the English referred to nighttime sensations of chest pressure from witches or other supernatural beings as the “mare,” from the Anglo-Saxon merran, meaning to crush. The term eventually morphed into nightmare—the crusher who comes in the night. …

Many who experience sleep paralysis also report sensations of floating, flying, falling, or leaving one’s body. The condition’s primary emotion, terror, sometimes yields to feelings of excitement, exhilaration, rapture, or ecstasy. “A small number of people, while acknowledging fear during initial episodes of sleep paralysis, come to enjoy the experience,” Cheyne says. …

Two brain systems contribute to sleep paralysis, Cheyne proposes. The most prominent one consists of inner-brain structures that monitor one’s surroundings for threats and launches responses to perceived dangers. As Cheyne sees it, REM-based activation of this system, in the absence of any real threat, triggers a sense of an ominous entity lurking nearby. Other neural areas that contribute to REM-dream imagery could draw on personal and cultural knowledge to flesh out the evil presence.

A second brain system, which includes sensory and motor parts of the brain’s outer layer, distinguishes one’s own body and self from those of other creatures. When REM activity prods this system, a person experiences sensations of floating, flying, falling, leaving one’s body, and other types of movement, Cheyne says. …

There is a kinship between waking nightmares starring Night Crushers and reports of alien abductions, McNally and Clancy find. For more than a decade, they have been studying people who claim to have been abducted by aliens from outer space. McNally and Clancy are convinced that these claims derive from sleep-paralysis hallucinations.

Robot on the run

From The Age:

Scientists running a pioneering experiment with “living robots” which think for themselves said they were amazed to find one escaping from the centre where it “lives”.

The small unit, called Gaak, was one of 12 taking part in a “survival of the fittest” test at the Magna science centre in Rotherham, South Yorkshire, which has been running since March.

Gaak made its bid for freedom yesterday after it had been taken out of the arena where hundreds of visitors watch the machines learning as they do daily battle for minor repairs.

Professor Noel Sharkey said he turned his back on the drone and returned 15 minutes later to find it had forced its way out of the small make-shift paddock it was being kept in.

He later found it had travelled down an access slope, through the front door of the centre and was eventually discovered at the main entrance to the car park when a visitor nearly flattened it with his car. …

And he added: “But there’s no need to worry, as although they can escape they are perfectly harmless and won’t be taking over just yet.”

The inevitability of taxation

business, overheard, politics, science / /

From Giampaolo Garzarelli’s Open Source Software and the Economics of Organization:

Whenever organizational forms present rapid change because of their strong ties to technology, public policy issues are always thornier than usual. Indeed, historically, it seems that every time that there’s the development of a new technology or production process, the government has to intervene in some fashion to regulate it or to extract rents from it. This point is well- encapsulated in the well-known catch-phrase attributed to Faraday. After Faraday was asked by a politician the purpose of his recently discovered principle of magnetic induction in 1831, he replied: “Sir, I do not know what it is good for. However, of one thing I am quite certain, some day you will tax it”.

More proof of time travel?

commonplace book, cool stuff, science, weird / /

From Ohio.com:

It was 11:15 p.m. on a warm June night in 1950, and the area of Times Square was buzzing with people leaving the theaters.

Suddenly, in the midst of traffic appeared an odd-looking man, about 30 years old. He wore mutton-chop whiskers and quaint clothing that had gone out of style decades before.

The man gawked at his surroundings, and then tried to dash away from the cars. He was struck by a cab and killed.

Police found on the dead man antique currency, business cards in the name of Rudolph Fentz, and a letter addressed to Fentz postmarked in 1876.

Assuming the man was Fentz, police sought the next of kin. But Fentz wasn’t listed in the telephone directory, and no one at the address on the business card and letter knew him.

Capt. Hubert V. Rihm eventually turned up a 1939 phone book listing a Rudolph Fentz Jr. When Rihm located the junior’s widow, she told him her father-in-law had vanished in 1876 after going out for a smoke.

That knowledge in hand, Rihm dug into old police files and found the missing-person report from 1876. The address given was the same as that on the dead man’s business cards.
