The Thieves Who Saved the Taliban

Thursday, February 10th, 2011

Pakistan has had some success against the Taliban along the border, but they don’t want too much success:

Over the last three years, Pakistan’s success against the Taliban, along the Afghan border, was partially the result of their using lots of helicopters. Dozens of U.S. AH-1F gunships and even more Russian Mi-17 transports were used heavily. But not so much now. The Pakistanis refuse to move on the last Taliban sanctuary in North Waziristan. The real reason is that they do not want to wipe out the Taliban completely, but the reasons given to nagging Americans are more along the lines of “it’s too expensive” or “we’re not ready yet”. One of the more expensive items is maintaining all those helicopters. The Pakistanis say that, in addition to the expense, the Taliban have scattered, and can’t be found, providing no targets for the helicopters. But American UAVs find and attack Taliban and al Qaeda leaders several times a week. The real reason for the Pakistani helicopters staying on the ground is that the money for maintenance has been stolen.

It’s happened before. When the Pakistani offensive against the Taliban began three years ago, one of the first things they had to do was halt the theft of the $7 million a month the U.S. was providing for the maintenance of all those helicopters. Along with the money, there were also some American technical experts, to help maintain the helicopters. But for over two years previously, most of that money was stolen by politicians and army commanders, and the helicopters spent much of their time on the ground. But when the order came down to go after the Taliban, the word went out to leave the helicopter maintenance money (or at least most of it) alone so the birds could be made ready to join the fight.

Strategic Deception

Thursday, February 10th, 2011

The Soviet Union used Western pacifists for its own purposes:

A fictitious pacifist movement has been set up in the Soviet Union and Professor Chazov, the personal physician of the General Secretary of the Communist Party, has been made head of it. There are some who say that the movement is controlled by the Soviet leadership through the person of Chazov. Chazov, in addition to being responsible for the health of the General Secretary, is a member of the Central Committee of the Communist Party, i.e. one of the leaders who has real power in his hands. There are very few people who can manipulate him.

The mighty machinery of the GUSM [Chief Directorate of Strategic Deception] was brought into operation in order to give this Communist leader some publicity. General Moshe Milshtein himself arrived in London in April 1982 to attend a conference of doctors opposed to nuclear warfare. There were many questions that had to be put to the general. What did he have to do with medicine? Where had he served, in what regiments and divisions? Where had he come by his genuine English accent? Did all Soviet generals speak such good English? And were all Soviet generals allowed to travel to Great Britain and conduct pacifist propaganda, or was it a privilege granted to a select few?

The result of this publicity stunt by the GUSM is well known — the ‘pacifist’ Chazov, who has never once been known to condemn the murder of children in Afghanistan or the presence of Soviet troops in Czechoslovakia, and who persecutes opponents of Communism in the USSR, received the Nobel Prize.

How Steve Jobs ‘out-Japanned’ Japan

Thursday, February 10th, 2011

Jeff Yang explains how Steve Jobs ‘out-Japanned’ Japan:

CES is the home of the mainstream, the chorus, the echo chamber; by not attending, Apple maintains its identity as the maverick, the soloist, the think-different visionary — even though its massive success has now made it the world’s eighth-largest consumer technology company by revenue.

That ability to express by omission holds a central place in Jobs’s management philosophy. As he told Fortune magazine in 2008, he’s as proud of the things Apple hasn’t done as the things it has done. “The great consumer electronics companies of the past had thousands of products,” he said. “We tend to focus much more. People think focus means saying yes to the thing you’ve got to focus on. But that’s not what it means at all. It means saying no to the hundred other good ideas.” (Jobs sometimes says this even more bluntly: Nike CEO Mark Parker likes to recount the advice Jobs gave him shortly after Parker’s promotion to the top spot: “You make some of the best products in the world — but you also make a lot of crap. Get rid of the crappy stuff.”)

Other companies fail to do things because they’ve overlooked potential openings or are cutting corners to save money; under Jobs, however, every spurned opportunity is a conscious, measured statement. It’s why the pundits who give Apple products poor reviews for not including industry-standard components — for instance, the iMac’s lack of a floppy drive — just aren’t getting it: Apple products are as defined by what they’re missing as much as by what they contain.

To understand why, one has to remember that Jobs spent much of the 1970s at the Los Altos Zen Center (alongside then-and-current Gov. Jerry Brown) and later studied extensively under the late Zen roshi Kobun Chino Otogawa — whom he designated as the official “spiritual advisor” for NeXT, the company he founded after being ejected as Apple’s CEO in 1986, and who served as officiant when he wed his wife Laurene in 1991.

Jobs’s immersion in Zen and passion for design almost certainly exposed him to the concept of ma, a central pillar of traditional Japanese aesthetics. Like many idioms relating to the intimate aspects of how a culture sees the world, it’s nearly impossible to accurately explain — it’s variously translated as “void,” “space” or “interval” — but it essentially describes how emptiness interacts with form, and how absence shapes substance. If someone were to ask you what makes a ring a meaningful object — the circle of metal it consists of, or the emptiness that that metal encompasses? — and you were to respond “both,” you’ve gotten as close to ma as the clumsy instrument of English allows.

While Jobs has never invoked the term in public — one of the aspects of his genius is the ability to keep even his most esoteric assertions in the realm of the instantly accessible — ma is at the core of the Jobsian way. And Jobs’ single-minded adherence to this idiosyncratically Japanese principle is, ironically, what has allowed Apple to compete with and beat Japan’s technology titans — most notably the company that for the past four decades dominated the world of consumer electronics: Sony.

Jobs has long been fascinated with Sony and its co-founder, Masaru Ibuka, who gave the new company its mission statement:

“Sony will be the company that is most known for transforming the global image of Japanese goods as being of poor quality.” It defined Sony by what it would not do — make bad products — making it something of an omission statement, if you will.

By way of example, Deutschman tells the story of how Sony entered the color TV marketplace, noting that in the Sixties, when color TV was going from 3% to 25% of the market, Sony was one of the few electronics companies that didn’t sell a color model. “People were telling Ibuka, ‘You have to come in to this market, everyone will take your market share,’” says Deutschman. “And Ibuka refused, saying, ‘No, we will only do great products. We will only do high quality goods. We will only do breakthrough technology.’”

As a result, the company found itself in a precarious financial situation, losing out to its primary rivals — until it came upon the aperture-grille technology that Sony unveiled in 1966 as the core of the Trinitron TV. A full 25% brighter than its rivals, Trinitron became the best-selling color TV for the next quarter century.

“At the time, Sony was committed to not releasing a crappy product just because the market was there; they waited until they had a truly revolutionary innovation, combined it with great design and then profited from it for long, long time,” says Deutschman. “For decades, Sony was a perfect place for engineers to fully use their creativity, because it was focused on bringing real meaning and benefit to society by making great products. Sadly, in the last couple of decades, Sony has lost its way.”

When I was in Japan a few years ago, I visited Tokyo’s high-tech district, Akihabara, to see the hot new things coming out of that famously gadget-obsessed country — and the hot new things on display were all Apple products:

Meanwhile, as Douglas Krone, CEO of Dynamism and Gizmine — sister companies that sell otherwise-unavailable Japanese gadgets to American early adopters — notes, the home of Sony has become the land of Apple.

“I was at a party last night in central Tokyo that happened to have a bunch of twentysomething guests,” he says. “Every time I saw something glowing, it was an iPhone. It was a chilling display of dominance — five years ago, you would have seen 99.9 percent Japanese handsets and 0.1 percent Nokias and MotoRAZRs. Softbank’s flagship stores look almost comical now, with rows and rows of iPhones broken only by the occasional row of iPads, in a space that used to have a wide array of handsets.”

Gracie Breakdown of UFC 126

Wednesday, February 9th, 2011

Rener Gracie and Rhalan Gracie provide a breakdown of UFC 126:

As they point out, Rocha displayed beautiful jiu-jitsu transitions against Ellenberger. They don’t mention that he seemed more interested in those beautiful transitions than in winning the MMA bout.

Anyway, they go into wonderful detail analyzing Rocha’s Kimura arm-bar attack from (under) the north-south turtle position. Rocha doesn’t sit through and sit up as much as in the variation I’ve used.

They also look at some of Jon “Bones” Jones’ amazing techniques, including his transition from D’Arce choke, to arm-in guillotine, to arm-out guillotine, to arm-out guillotine with his own forearm over the shoulder — a variation I just learned from Rodrigo Gracie — to push-grip guillotine — made famous by last year’s TUF competitor, Cody McKenzie.

Fruits from the Tree of Malice

Wednesday, February 9th, 2011

According to the KGB’s estimates, Claire Berlinski reports, outraged Muslims cost approximately a quarter-rupee apiece:

The KGB station in India is capable of organizing a protest demonstration at the U.S. Embassy to India, with up to 20,000 Muslims participating. The expenses for organizing the demonstration would amount to 5,000 Indian rupees and be covered from the funds allocated by the CPSU Central Committee for special measures in India in 1969–1971.

A Soviet document from 1970 details how the US became known as a racist power:

Because the rise of negro protest in the USA will bring definite difficulties to the ruling classes of the USA and will distract the attention of the Nixon administration from pursuing an active foreign policy, we would consider it feasible to implement a number of measures to support this movement and to assist its growth.

Therefore it is recommended to utilize the possibilities of the KGB in African countries to inspire political and public figures, youth, trade union and nationalist organizations to issue petitions, requests and statements to the UN, U.S. embassies in their countries and the U.S. government in defense of the rights of American negroes. To publish articles and letters accusing the U.S. government of genocide in the press of various African countries. Employing the possibilities of the KGB in New York and Washington, to influence the “Black Panthers” to address appeals to the UN and other international bodies for assistance in bringing the U.S. government’s policy of genocide toward American negroes to an end.

Berlinski’s larger point is that these documents demonstrating Soviet misdeeds — support for Middle-East terrorists in particular — have received virtually no coverage in the mainstream media.

Slave Girls and Pickled Heads

Wednesday, February 9th, 2011

Berlin’s Pergamon Museum is finally displaying Max von Oppenheim’s spectacular 3,000-year-old finds from Syria — which they just painstakingly reassembled, over the course of the last decade, to partially undo the damage of Allied bombing in World War II:

In 1943, Allied phosphorus bombs rained down on the statues from the Middle East, setting off a 900-degree Celsius (1,650 degrees Fahrenheit) inferno. As the fire was being extinguished, the sculptures shattered, leaving behind 27,000 pieces of basalt, some no bigger than a human thumb, which spent the Cold War stored in a basement.

Like Heinrich Schliemann, who discovered Troy, Max von Oppenheim (1860-1946) was a self-taught archeologist:

In 1886, he traveled through Morocco, where conditions were practically medieval at the time. Wearing a disguise, he entered a mosque in Fez, despite the threat of being put to death if discovered. Later, he bought a Berber girl at a slave auction and was served the pickled heads of the local clan’s enemies in a remote village.

His subsequent journeys took him as far as Iraq. In 1896, Oppenheim moved to Cairo, where he lived in a villa surrounded by palm trees, together with his gardener, Soliman, six servants and a French chef.

Oppenheim, who spoke fluent Arabic by now, stayed in tents with sheiks and, wearing turbans and robes, chatted with Druze princes.

Given his colonial ambitions, Kaiser Wilhelm II needed people like Oppenheim, so he hired him to work at the German consulate in Egypt.

In addition to performing his diplomatic duties, the colorful banker’s son collected 42,000 books and studied the customs of the Orient. His groundbreaking work on the history of the Bedouins was just recently rediscovered in Saudi Arabia.

Drawing on his father’s deep pockets, the scholar hosted lavish “dancing festivals” in Cairo, where he received British ambassadors, Polish princesses and the American hotel tycoon John Jacob Astor (who later drowned when the Titanic sank). When Agatha Christie toured the Orient, it was still filled with legends of the fabulous wealth of “El Baron.”

In 1911, Oppenheim set out into the desert with 1,000 camels carrying 21 tons of expedition gear, including wagons and 800 meters of rail track. It had been an unusually harsh winter in northern Mesopotamia, and the stinking cadavers of animals littered the sand.

His excavation team included up to 500 Bedouins, as well as a doctor, cooks, a photographer and several skilled excavation experts.

Just beneath the surface, the excavators found stone sphinxes, lions and dark basalt panels bearing reliefs of ships, camels and club-wielding dignitaries. The reliefs had once adorned the “Western Palace” built long ago by a mysterious King Kapara.

No mention of the Ark of the Covenant or the Holy Grail.

No soldier should be afraid of blood

Wednesday, February 9th, 2011

No soldier should be afraid of blood — especially not a spetsnaz commando:

It used to be thought that a soldier could be accustomed to the sight of blood gradually — first a little blood and then more day by day. But experts have thrown out this view. The spetsnaz soldier’s first encounter with blood should be, they argue, quite unexpected and in copious quantities. In the course of his career as a fighting man there will be a whole lot of monstrous things which will spring up in front of him without any warning at all. So he should get used to being unsurprised at anything and afraid of nothing.

A group of young spetsnaz soldiers are hauled out of bed at night because of an emergency, and sent in pursuit of a ‘spy’. The worse the weather the better. Best of all when there is torrential rain, a gusty wind, mud and slush. Many kilometres of obstacles — broken-down stairs, holes in walls, ropes across holes and ditches. The platoon of young soldiers are completely out of breath, their hearts beating fast. Their feet slip, their hands are scratched and bruised. Forward! Everyone is bad-tempered — the officers and especially the men. The soldier can give vent to his anger only by punching some weaker fellow-sufferer in the face and maybe getting a kick in the ribs in reply. The area is dotted with ruined houses, everything is smashed, ripped apart, and there’s broken glass everywhere. Everything is wet and slippery, and there are never-ending obstacles with searchlights trained on them. But they don’t help: they only hinder, blinding the men as they scramble over.

Now they come to a dark cellar, with the doors ripped off the hinges. Everybody down. Along the corridor. Then there’s water ahead. The whole group running at full tilt without slowing down rushes straight into some sticky liquid. A blinding light flashes on. It’s not water they are in — it’s blood. Blood up to the knees, the waist, the chest. On the walls and the ceiling are chunks of rotten flesh, piles of bleeding entrails. The steps are slippery from slimy bits of brain. Undecided, the young soldiers jam the corridor.

Then somebody in the darkness lets a huge dog off its chain. There is only one way out — through the blood. Only forwards, where there is a wide passageway and a staircase upwards. Where on earth could they get so much blood? From the slaughter-house, of course. It is not so difficult to make the tank of blood. It can be narrow and not very deep, but it must be twisting and there must be a very low ceiling over it. The building in which the tank of blood is arranged can be quite small, but piles of rotten boards, beams and concrete slabs must be tipped into it. Even in very limited space it is possible to create the impression that you are in an endless labyrinth overflowing with blood. The most important thing is to have plenty of twists and turns, holes, gaps, dead ends and doors.
[...]
And there’s something else: the tank of blood must not be the final obstacle that night. The greatest mistake is to drive the men through the tank and then bring the exercise to an end, leaving them to clean themselves up and go to bed. In that case the blood will only appear to them as a terrible dream. Keep driving them on over more and more obstacles.

Age Gain Now Empathy System

Wednesday, February 9th, 2011

MIT’s AgeLab has produced the Age Gain Now Empathy System, or Agnes, to help product designers and marketers better understand older adults and create innovative products for them:

At first glance, it may look like a mere souped-up jumpsuit. A helmet, attached by cords to a pelvic harness, cramps my neck and spine. Yellow-paned goggles muddy my vision. Plastic bands, running from the harness to each arm, clip my wingspan. Compression knee bands discourage bending. Plastic shoes, with uneven Styrofoam pads for soles, throw off my center of gravity. Layers of surgical gloves make me all thumbs.

We’d have been happy to work with them

Tuesday, February 8th, 2011

A half century of reading about the Arabs has left John Derbyshire with two strong impressions:

One: a rational, orderly, and fair system of government is beyond Arab capabilities. And two: They are the all-time world champions at blaming other people for their problems.

He gives a little history and describes US interests in the region:

We wanted to keep the oil flowing. We didn’t want to see Israel annihilated. We worked with who we found, bribing as necessary. To the Arab in the street this looked like, quote, “the U.S.A. colluding with the Jews to prop up corrupt dictators.” Hey, pal: if you’d gotten yourself some non-corrupt non-dictators, we’d have been happy to work with them.

Liberal democracy is not a possible outcome. Here’s what is:

  • Evens: an Iran-Gaza outcome, i.e. religious fanatics take over the place and start arming up for a war against the Jews.
  • Two to one: regime survival: the Mubarak regime, with or without Mubarak, survives the crisis, supported by (a) the common people’s desire for a restoration of order under any conditions, (b) the military’s desire to continue living the harlot’s life — power without responsibility — on U.S. subsidies, and (c) backing from key international playahs, notably the Saudis, the Europeans, and of course us.
  • Five to one: a military coup, some bright young officer in the Nasser-Gaddafi-Saddam mould sweeping away the old order and starting a new cycle of gangster-dictatorship.

Each outcome has its pros and cons:

The big pro of an Iran-Gaza outcome would be we’d no longer be on the hook for the two billion dollar annual bribe we pay Mubarak to behave himself. The con is of course another crazy wild-card actor in the Mideast.

The pro of regime survival is we wouldn’t have to think about the stinking place for another decade or two; the con is, they’d want a big cost-of-living adjustment on that annual bribe, which of course we’d have to borrow from the ChiComs.

The pro of a military coup is that the military is the least religious and most bribable faction in Egypt and has the ethos and the means to impose order; the con is that the cost-of-living adjustment in the bribe we pay them will be twice as big again.

Derb also gives a shout-out to our man on the inside, Foseti.

A Statistically Impossible Lack of Diversity

Tuesday, February 8th, 2011

Jonathan Haidt recently polled the 1,000 social scientists at the Society for Personality and Social Psychology’s conference and found a statistically impossible lack of diversity — just three admitted conservatives and a few dozen centrists and libertarians in a sea of liberals, versus 40 percent conservative and 20 percent liberal in the population at large:

“Anywhere in the world that social psychologists see women or minorities underrepresented by a factor of two or three, our minds jump to discrimination as the explanation,” said Dr. Haidt, who called himself a longtime liberal turned centrist. “But when we find out that conservatives are underrepresented among us by a factor of more than 100, suddenly everyone finds it quite easy to generate alternate explanations.”

Dr. Haidt (pronounced height) told the audience that he had been corresponding with a couple of non-liberal graduate students in social psychology whose experiences reminded him of closeted gay students in the 1980s. He quoted — anonymously — from their e-mails describing how they hid their feelings when colleagues made political small talk and jokes predicated on the assumption that everyone was a liberal.

“I consider myself very middle-of-the-road politically: a social liberal but fiscal conservative. Nonetheless, I avoid the topic of politics around work,” one student wrote. “Given what I’ve read of the literature, I am certain any research I conducted in political psychology would provide contrary findings and, therefore, go unpublished. Although I think I could make a substantial contribution to the knowledge base, and would be excited to do so, I will not.”
[...]
The fields of psychology, sociology and anthropology have long attracted liberals, but they became more exclusive after the 1960s, according to Dr. Haidt. “The fight for civil rights and against racism became the sacred cause unifying the left throughout American society, and within the academy,” he said, arguing that this shared morality both “binds and blinds.”

“If a group circles around sacred values, they will evolve into a tribal-moral community,” he said. “They’ll embrace science whenever it supports their sacred values, but they’ll ditch it or distort it as soon as it threatens a sacred value.” It’s easy for social scientists to observe this process in other communities, like the fundamentalist Christians who embrace “intelligent design” while rejecting Darwinism. But academics can be selective, too, as Daniel Patrick Moynihan found in 1965 when he warned about the rise of unmarried parenthood and welfare dependency among blacks — violating the taboo against criticizing victims of racism.

“Moynihan was shunned by many of his colleagues at Harvard as racist,” Dr. Haidt said. “Open-minded inquiry into the problems of the black family was shut down for decades, precisely the decades in which it was most urgently needed. Only in the last few years have liberal sociologists begun to acknowledge that Moynihan was right all along.”

Similarly, Larry Summers, then president of Harvard, was ostracized in 2005 for wondering publicly whether the preponderance of male professors in some top math and science departments might be due partly to the larger variance in I.Q. scores among men (meaning there are more men at the very high and very low ends). “This was not a permissible hypothesis,” Dr. Haidt said. “It blamed the victims rather than the powerful. The outrage ultimately led to his resignation. We psychologists should have been outraged by the outrage. We should have defended his right to think freely.”

Instead, the taboo against discussing sex differences was reinforced, so universities and the National Science Foundation went on spending tens of millions of dollars on research and programs based on the assumption that female scientists faced discrimination and various forms of unconscious bias. But that assumption has been repeatedly contradicted, most recently in a study published Monday in the Proceedings of the National Academy of Sciences by two Cornell psychologists, Stephen J. Ceci and Wendy M. Williams. After reviewing two decades of research, they report that a woman in academic science typically fares as well as, if not better than, a comparable man when it comes to being interviewed, hired, promoted, financed and published.

“Thus,” they conclude, “the ongoing focus on sex discrimination in reviewing, interviewing and hiring represents costly, misplaced effort. Society is engaged in the present in solving problems of the past.” Instead of presuming discrimination in science or expecting the sexes to show equal interest in every discipline, the Cornell researchers say, universities should make it easier for women in any field to combine scholarship with family responsibilities.

He is no good for spetsnaz!

Tuesday, February 8th, 2011

Soviet battle training is based on some very Soviet experiences:

They have established that in the past training had been carried out incorrectly, on the principle of moving from the simple to the more difficult. A soldier was first taught to jump from a low level, to pack his parachute, to land properly, and so forth, with the prospect later of learning to make a real parachute jump. But the longer the process of the initial training was drawn out, the longer the soldier was made to wait, the more he began to fear making the jump. Experience acquired in previous wars also shows that reservists, who were trained for only a few days and then thrown into battle, in the majority of cases performed very well. They were sometimes short of training, but they always had enough courage. The reverse was also shown to be true. In the First World War the best Russian regiments stayed in Saint Petersburg. They protected the Emperor and they were trained only to be used in the most critical situations. The longer the war went on, the less inclined the guards regiments became to fight. The war dragged on, turned into a senseless carve-up, and finally the possibility arose of a quick end to it. To bring the end nearer the Emperor decided to make use of his guards….

The Revolution of 1917 was no revolution. It was simply a revolt by the guards in just one city in a huge empire. The soldiers no longer wanted to fight; they were afraid of war and did not want to die for nothing. Throughout the country there were numerous parties all of which were in favour of ending the war, and only one of them called for peace. The soldiers put their trust in that party. Meanwhile, the regiments that were fighting at the front had suffered enormous losses and their morale was very low, but they had not thought of dispersing to their homes. The front collapsed only when the central authority in Saint Petersburg collapsed.

Lenin’s party, which seized power in that vast empire by means of the bayonets of terrified guards in the rear, drew the correct conclusions. Today soldiers are not kept for long in the rear and they don’t spend much time in training. It is judged much wiser to throw the young soldier straight into battle, to put those who remain alive into the reserve, reinforce with fresh reservists, and into battle again. The title of ‘guards’ is then granted only in the course of battle, and only to those units that have suffered heavy losses but kept fighting.

Spetsnaz training takes this to the next level:

The most important feature of the training of a young spetsnaz soldier is not to give him time to reflect about what is ahead for him. He should come up against danger and terror and unpleasantness unexpectedly and not have time to be scared. When he overcomes this obstacle, he will be proud of himself, of his own daring, determination and ability to take risks. And subsequently he will not be afraid.

Unpleasant surprises are always awaiting the spetsnaz soldier in the first stage of his service, sometimes in the most unlikely situations. He enters a classroom door and they throw a snake round his neck. He is roused in the morning and leaps out of bed to find, suddenly, an enormous grey rat in his boot. On a Saturday evening, when it seems that a hard week is behind him, he is grabbed and thrown into a small prison cell with a snarling dog. The first parachute jump is also dealt with unexpectedly. A quite short course of instruction, then into the sky and straight away out of the hatch. What if he smashes himself up? The answer, as usual: he is no good for spetsnaz!

Later the soldier receives his full training, both theoretical and practical, including ways to deal with a snake round his neck or a rat in his boot. But by then the soldier goes to his training classes without any fear of what is to come, because the most frightful things are already behind him.

Navigating by Sunstone

Tuesday, February 8th, 2011

In the 1960s, Danish archaeologist Thorkild Ramskou suggested that the Vikings navigated by sunstone, using its polarization to find the sun through clouds and fog:

The idea of navigating by polarized skylight originated with a Viking saga, in which the Norse hero Sigurd “grabbed a sunstone, looked at the sky and saw from where the light came, from which he guessed the position of the invisible Sun.” The stone would like have been made of a so-called birefringent material, like calcite or certain plastics, that can split light into separate rays.

The atmosphere similarly splits sunlight into a pattern of concentric rings. Looking through the crystal and rotating it would make the sky appear to brighten and fade, as certain directions of light were transmitted or blocked. When the light coming through the crystal was polarized the same way as through the atmosphere, the crystal would appear brightest and points toward the sun. By checking the polarization at two different points in the sky, the navigators could determine the invisible sun’s location, and hold a torch in that position to cast a shadow on the sundial.

Optics expert Gábor Horváth of Hungary’s Eötvös University ran five experiments to see if the proposed method worked — which it did, even in clouds and fog, but not when the sky was completely overcast.

Steven Seagal Taught Anderson Silva the Front Kick?

Monday, February 7th, 2011

Steven Seagal claims to have taught Anderson Silva the front kick he used to knock out Vitor Belfor in Saturday night’s UFC:

Another interview:

He seems so earnest. So, he’s totally delusional, right? Well, maybe — but watch this:

I’m really not sure what to make of this.
