Everybody Loves the Assassins

Friday, May 24th, 2013

Tim Cahill travels the Iranian countryside, hiking up to the ruins of the Assassins’ castles:

So we walked up the sloping back side, among sagelike flowering bushes watered by the snowmelt from a few late drifts. Snow-crested mountains soared all about and the sun reflected off the glaciers like so many mirrors. We summited, then found a way down on the east side of the face, skiing in our boots through steeply sloping scree fields that led eventually into decorative and absurdly ornate fields of wildflowers. There were yellow buttercups and purple and white flowers I couldn’t identify, interspersed in various swirling patterns. I saw there the elements of complex design so appealing in Persian rugs or in the tile work of various mosques.

It was still several miles across a vast marshy meadow to camp, and when we dropped over the lip of an undulating swale, six or seven huge shaggy dogs, each weighing in excess of 100 pounds, surrounded us. There were a lot of teeth in evidence, and perhaps a thousand sheep and goats grazing nearby. A shepherd shouted a command and the dogs dispersed, grumbling among themselves. Many of them, I noticed now, were pretty banged-up. They walked with an assortment of limps.

The dogs were a kind of sag gorg, a wolf dog, and some wore thick leather collars with metal studs on them, because wolves always go for the neck in a fight.

“How many times a year do they fight the wolves?” I asked.

“Five or six times a night,” the shepherd said. It seemed an implausible number to me, but then again, it did explain why half the dogs were limping.

Later we watched seven shepherds milk their animals, all in a chaos of dust and finely organized confusion. Shahram translated a few questions back and forth. Later, on the way back to camp, Shahram said, “You are the first Americans they have ever seen. They wanted to know how relations were between our countries.”

“What did you tell them?”

“Could be better. I said that you guys came to meet the people and see the culture here. I said that was good, because the image Americans have of Iran is all desert and camels and terrorists. I said what you were doing would help ignorant people.” We walked on a bit. “Of course I was bullshitting.”

“Actually,” I said, “you weren’t.”

His main lesson learned: Iranians throw trash everywhere — which is the same lesson you learn in India, etc.

When Real Men Wore High Heels

Thursday, April 25th, 2013

Kinky BootsHigh-heel, over-the-knee boots may be coming back into fashion, but they’re seen as awfully flamboyant on a man. Three hundred years ago it would have been scandalous for a woman to be seen wearing them. Peter Turchin looks back at when real men wore high heels:

The starting point of this evolution was the invention the stirrup, probably by the Mongolian nomadic people called Xianbei around 300 AD. This was such a useful invention that by the sixth century it spread through all of Eurasia, from Japan to Europe. By providing the rider with unprecedented stability, the stirrup made heavy cavalry (actually, any kind of cavalry) much more effective. Some historians even argued that the stirrup gave rise to feudalism in medieval Europe, and something very similar in Japan (take this with a grain of salt).

The problem with the stirrup is that when you fall off the horse (and if you ride horses a lot, especially under the chaotic conditions of war, you will inevitably do so once in a while), there is a danger of your foot being caught in the stirrup. Countless riders have been dragged to their deaths by panicking horses.

And here is where a properly designed stirrup/boot combination comes in. An iron stirrup with large enough opening for the boot allows you to kick it off as you fall. A high heel, on the other hand, gives you the stability by preventing the foot from slipping through the stirrup. It helps to have a very slick, slippery sole for ease of foot extraction in case of mishap.

High heels and slippery soles make for rather uncomfortable walking (I would not recommend wearing true cowboy boots in New England’s winter!). But for riding it’s just right.

Cowboy Boots

In the early-modern Europe high-heeled footwear also served an important function of distinguishing the nobility from the peasants. Then came the Age of Revolutions (from the French Revolution of 1789 to the Paris Commune of 1870), which introduced a new era that stressed equality and blurred class lines. At the same time, the horses gradually lost their function as the means of land transport, being replaced by railroads and the automobile. And so high heels lost their functionality, and became just a fashion fad. Or nostalgia.

Havard “Kickalicious” Rugland has in fact been signed by the Detroit Lions — to compete against NFL veteran David Akers to replace retiring kicker Jason Hanson.

If You Want to Stop Gun Violence, Start With Bullets

Tuesday, February 12th, 2013

Wired‘s Danger Room has published an embarrassingly bad infographic and accompanying article in which Joanna Pearlstein tries to argue that if you want to stop gun violence, you need to start with bullets:

Guns don’t kill people; people don’t kill people; bullets kill people. As the nation debates, again, the best way to curb gun violence, many of the questions focus on the firearms themselves. But an equally important consideration is ammunition. Roughly 10 billion rounds are manufactured in the US each year, with a weight equal to two Titanics. More to the point, it’s enough bullets to pump 32 rounds into every man, woman, and child in America.

Actually, people do kill people, all the time, often without guns or bullets. When they do use guns to shoot bullets, it only takes a few rounds to commit a massacre. Bullets are not the bottleneck there.

On the other hand, it takes thousands of rounds to become a competent shooter. In fact, competitive shooters can go through tens of thousands of rounds per year. Competitive shooters kill no one.

Radical planes take shape

Tuesday, November 13th, 2012

Airliners have not changed much outwardly in 60 years, but that may soon change:

Earlier improvements went mostly unnoticed because they focused on building better and quieter turbine engines with higher performance and improved fuel consumption. There have also been huge strides in computer controls and fly-by-wire systems, which make a big difference to the pilot, but not to the passengers. And in recent years, the biggest development has been the use of strong, but lightweight plastics and composite materials rather than metals, reducing the weight of planes and the amount of fuel they need to burn. This has also allowed the development of “radical” new planes like the giant Airbus A380 and the Boeing Dreamliner.

[...]

A team from MIT in Cambridge, Massachusetts, for example, put forward the D8 for consideration by Nasa. This “double-bubble” aircraft design, features a double-wide fuselage composed of two standard body cylinders melded together side-by-side, as well as low-swept wings that cut drag and weight. The idea of the wider body shape is to increase lift generated by the fuselage, rather than it being mostly dead weight slung between two wings. The extra lift and reduced drag cuts back on the quantity of fuel that the engines must burn. If the jet were built today from standard aluminum alloys it could provide a 50% reduction in fuel use, according to the MIT designers; a low-mass polymer-composite version could give 70% efficiency gains. In addition, because the D8’s turbine engines sit on top of the fuselage in a box-shaped tail, they would cut the amount of engine noise broadcast to the ground.

The D8’s idea for generating greater lift is taken to an extreme in another design called the N3-X hybrid wing-body airplane, which Nasa developed in-house. At first glance, the N3-X looks a lot like a so-called flying wing design, used by planes such as the US Air Force’s B-2 stealth bomber. These comprise a single, thick triangular wing that enclose all of the plane’s contents – cockpit, stores, engines, fuel tanks and flight surfaces. But, unlike the B-2 flying wing, the N3-X hybrid wing-body also features two thin, rather conventional wings attached to the sides of its ultra-wide fuselage.

The primary advantage of the hybrid, or blended, wing-body design is better fuel efficiency, Del Rosario says. Like a flying wing, the hybrid aircraft produces lift with its entire aerodynamic airframe, thus ridding itself of the drag associated with the cylindrical fuselage and the tail surfaces of a conventional plane. As with the D8, the more lift that can be produced overall, the less effort is needed from the engines, which in turn means less fuel must be burned. Fuel efficiency could be raised further by building the airframe from lightweight polymer composite materials instead of metals, Del Rosario says.

[...]

Nasa’s N3-X is also designed around a completely new engine concept, called turboelectric distributed propulsion. It splits the main functions of a standard turbine engine in two — generating power by burning fuel and creating thrust by blowing air rearward with a large fan.

The idea is to use two large turbine engines to drive electric generators that would produce electricity to power 15 electric motor-driven, thrust-producing fans that would be embedded across the top rear of the broad fuselage. Such a configuration could be very efficient, Del Rosario says. The array of small electric propulsion fans at the stern of N3-X enables the designers to cut drag significantly by accelerating the flow of drag-causing air moving over the upper surface of the fuselage, keeping efficiency-sapping air friction at a minimum. Like the D8, the top-mounted propulsor fans would also effectively lower noise emissions because the body would come between them and the ground below.

The NFL Moves Back Into the Dorms

Tuesday, September 11th, 2012

Former Baylor quarterback Robert Griffin made his NFL debut with the Washington Redskins Sunday, but he continued to lead a college-style offense:

Last season, the Redskins ran out of the shotgun 33% of the time — just shy of the 41% average for all NFL teams. On Sunday, however, they ran it on 20 of the first 23 offensive snaps, something you hardly ever see outside college campuses.

On just the third snap, one play after running a shotgun option, Shanahan’s Baylorskins ran the pistol. This formation, in which Griffin started from the shotgun with the running back lined up behind him, was a clear case of pandering to Griffin’s skills. Montgomery noted that this exact play was “worked hard” early in Griffin’s college career. After taking the snap, Griffin faked a handoff then threw a quick dart pass to receiver Pierre Garcon who was split wide, for a 12-yard gain.

At the start of the second quarter, Griffin lined up in shotgun with a running back to his right again—but with another one directly behind him (see photo). This time, after faking the handoff to running back Alfred Morris, Griffin rolled out to his left, eluded the rushing defensive line and threw the ball across the field for a 26-yard strike to tight end Fred Davis.

Griffin’s statistics from Sunday don’t look like NFL statistics: According to researchers at Pro Football Focus, Griffin threw 13 of his 25 passes within nine yards of the line of scrimmage and threw more than 20 yards on just two plays. In the same game, Saints quarterback Drew Brees, a more-traditional NFL pocket passer, threw 11 passes longer than 20 yards.

After the game, Redskins players and coaches spoke about how important it was that the Saints didn’t know what was coming. Asked about this, Saints interim coach Aaron Kromer said his team wasn’t surprised to see Griffin running bootlegs, quarterback runs and “read options,” they just couldn’t stop them.

The big question for the copycat NFL is whether Griffin’s success will trigger a Pavlovian response among other coaches.

The real games in the Olympic Village

Thursday, July 19th, 2012

The real games in the Olympic Village will not be televised, Sam Alipour reminds us:

For most Olympians, the ramp-up to the Games is lonely. Not unlike movie stars on a far-flung movie shoot, the Olympics present the perfect opportunity to find a partner who understands where they’re coming from. “Think about how hard it is to meet someone,” Azevedo says. “Now take an Olympian who trains from 6 a.m. until 5 p.m. every day. When the hell are you supposed to meet someone? Now the pressure is done, you’re meeting like-minded people … and boom.”

Dad’s Traveling Think Tank

Sunday, July 15th, 2012

When Dan Zevin was young, he often found himself riding in his dad’s traveling think tank:

In my dad’s generation, a man’s car was his castle. And his kids were his captive audience. We listened to his music. We answered his questions. We stared out his rhombus-shaped windows as he shared fatherly wisdom that we’d later refer to as “The Tao of the Monte Carlo.”

“In life, you will find there are always people ahead of you and people behind you.” (What he told us whenever we were stuck in traffic.)

“Don’t let the sound of your own wheels drive you crazy.” (The line he’d repeat no matter how often we heard it on his Eagles “Greatest Hits” 8-track.)

“Remember to follow through.” (The advice he dispensed while driving us to tennis.) “And I’m not just talking about swinging a racket,” he’d add. “I’m telling you how to succeed in the world.”

[...]

When I take my dad for a spin in the Maxivan, he seems rather freaked out. It’s like he’s stepped into an alternate universe where parents think it’s their job to do whatever it takes to keep their kids happy. The truth is, I’m following a very old-fashioned tenet of parenting: Children should be seen and not heard. And thanks to that fully loaded Maxivan, my kids are not heard. They are not heard shouting at each other, fake-belching at each other or telling on each other. Contained in their captain’s chairs and distracted by “Toy Story 3,” fingers will not be inserted into neighboring ears, Goldfish will not fly, chaos will turn to quiet.

It wasn’t supposed to be like this. I wasn’t supposed to be the dad who disciplines his kids by making them watch DVDs.

Im Dong-Hyun

Wednesday, July 11th, 2012

South Korean Olympic archer Im Dong-Hyun is legally blind:

Every archer who steps out onto Lord’s cricket ground to compete in the London Olympics will have to hit a target roughly the size of an apple from a distance just shy of the length of a football pitch.

But for one archer, the yellow circle at the heart of the target will be a fuzzy blob. Im Dong-hyun, a softly spoken 25-year-old Korean with burnt orange highlights in his hair, is widely considered the best archer in the world.

He has two Olympic gold medals from the team events in Athens and Beijing. He holds the current world record for 72 arrows, with a score of 687 out of 720.

But according to the Korean Archery Federation, he is legally blind, with vision of 20/100 in his right eye and 20/200 in his left. In his words, it leaves the rainbow colours of the archery target looking “as if different types of paint have been dropped in water. The lines are blurred.”

Im began losing his eyesight as a teenager, when he was already an established archer, although there are no tell-tale signs.

“I do not feel that I need to wear glasses. I am not myopic, I am far-sighted,” he said, after one of his daily training sessions at his training centre in Seoul.

The Virus that Inspired the Whole Zombie Genre

Thursday, June 28th, 2012

The virus that inspired the whole zombie genre is, of course, rabies:

It’s a bullet shaped virus that can be transmitted through bodily fluids like saliva. Once in the body, it heads for the brain, causing swelling and a zombie-movie set of symptoms.

Actually, there are two kinds of rabies: dumb rabies and furious rabies. Dumb rabies is tougher to diagnose, since it comes on through slurred speech, loss of function, paralysis, coma, and death. Furious rabies, which comprises fifty percent of animal cases and two thirds of human cases, is where the horror movie stereotypes come from.

After an incubation period that could last anywhere from a week to several years, people with rabiees suddenly become antsy and hyperactive. They start becoming disoriented and lose lucidity. Eventually, they develop more aggressive symptoms. The mildest of these symptoms is simple irritability. People, metaphorically, snap at those around them. Because they’re hyperactive and restless, they tend to get annoyed with many people very quickly. As the disease progresses, though, they become more physically violent. A man in Mumbai became so violent that hospital personnel evacuated his room and eventually had to call the police and the fire brigade to pacify him enough for a sedative.

[...]

Patients become afraid of bright lights and moving air, so they try to hide in dark and confined places. They fall silent, in part because they become so afraid of the sound of their own voice, it’s impossible for them to speak. Most notoriously, patients with “furious rabies” develop strange appetites. Animals with rabies, although they can barely swallow water, have been seen to eat sticks and rocks. They also seem to undergo a compulsive need to bite. Scientists think that this is the disease trying, evolutionarily speaking, to strike out and get transmitted to a new host. This is the crux of the zombie mythology. A bite means a death of the self — loss of speech, coherence, lucidity, and ability to control aggressive impulses — and a rebirth as a silent, unresting zombie, endlessly driven to look for new people to bite.

Notes from Iceland

Monday, June 4th, 2012

Justin Erik Halldór Smith shares his notes from Iceland, which he is visiting for the first time in many years:

A series of small hops then, brings one from Europe to North America, and even in the absence of archaeological evidence it is not hard to understand why, when Jacques Cartier sailed up the St. Lawrence in the 1530s, local Iroquois ran out to greet the ship with furs in hand, ready, to all appearances, to resume a well established trade. The Basques and the Norse are the likely first-comers in those parts. Of the latter, an early-medieval settlement in Newfoundland is now considered a certainty, while their colony in southwestern Greenland, well documented both archaeologically and textually, is know to have endured for several generations.

The Norse were preceded in Greenland by Skrælingjar, which is to say Inuit, but only if we consider that massive island as a whole. When the Norse established their settlement in the 10th century, the Inuit were confined to the northern part of the island. Norse and Inuit coexisted in the same region from the 13th century, and by the 15th century the Norse had been entirely driven out. As far as we can tell, Scandinavians were also preceded in Iceland by an indigenous people, of sorts, even if they do not meet our ordinary criteria for counting as such: the so-called Papar are thought to have been Irish hermits, probably monks, who drifted up on rafts by mistake, and hunted and gathered for bare subsistence. (Their presence as well remains unconfirmed by archaeology, and is based entirely on textual sources, as well as on toponymy: in particular, the Vestmannaeyjar are islands off the south coast of Iceland, thought to have been settled by the ‘Westmen’, a Norse designation for the Irish.)

The Skrælings and the Papar together should cause us to reconsider our ordinary understanding of indigenousness: the Inuit came after the Vikings to southern Greenland, and drove the Vikings out thanks to their superior adaptation to the environmental demands of the region; the Irish came first to Iceland, were vastly more primitive than the Vikings who arrived after them, and were exterminated or assimilated. (I would argue, in fact, that there are many good reasons for seeing the Celtic nations of Europe as aboriginal within Europe proper, and not only on a distant satellite of Europe, but that’s another topic.) The matter gets even more counterintuitive when we consider that at the moment of first contact the indigenous hunter-gatherers were Christians, while the invading Europeans were pagans.

As is well known, this point of difference would not remain an issue for long, not only because the Celtic element would soon be entirely erased, but also because Iceland would be converted to Christianity, en masse, just before the dawn of the 2nd millennium. 999 CE is extremely early for such a distant extremity of the West. Lithuania and neighboring Baltic regions, by contrast, squarely on the mainland and practically absorbed into the Prussian sphere of influence by the high middle ages, would nonetheless hold out against conversion until the 15th and 16th centuries. Nonetheless, as might be expected in such a case of mass conversion, the majority of the converted likely had little idea —and some, out on their homesteads, under the glacier, at first surely had no idea— of what was going on. Even those who did know that they were now to call themselves ‘Christian’, we may assume, probably brought with this new name a universe of connotations that would have been quite foreign to the Romans who believed they had won a whole island, all at once, to the true faith.

To return to the ethnographic data from a neighboring island, we know from the early-20th-century explorer and anthropologist Knud Rasmussen that Inuit conversion was in fact a movement within one and the same universe of signification. Rasmussen reports that Greenlandic Inuit shamans would take their ‘first communion’ by ceremonially devouring those organs of the walrus that had hitherto been prohibited to men of their status. The body of Christ as tabooed walrus meat: that is the essence of conversion. Should we suppose that the case of the pagan Icelanders was much different? They were ‘white’ and originally European, but so what? These categories didn’t mean anything at all at the time.

And so we find the well-known survival of pagan preoccupations well after 999. Unlike the case of Britain, where charlatan neopagans began in the 19th century to construct a wholly imaginary romantic past of high priests and priestesses, in Iceland the enduring power of animistic explanations for natural phenomena, complete with personified forces inhabiting every ditch and spring, is well attested by both indigenous and outside sources. The 16th-century Swedish author Olaus Magnus gives us a lengthy account in his Historia de gentibus septentrionalibus [History of the Northern Peoples] of the enduring folk-beliefs, including all the spells and incantations, of the Icelanders, and some decades later the German scientist and astrologer Johannes Kepler claims in his Somnium (at least if we take the protagonist as a stand-in for the author) that his own mother was Icelandic, that her name was Fiolxhilda, and that she was (therefore) a witch. (Kepler took Iceland to be the ideal spot from which to teletransport to the moon.)

So paganism lived on, and the conversion was an ambiguous affair. One of the pièces de résistance of the stunning, and stunningly empty, National Museum of Iceland is a small figurine, in bronze, dated to around the beginning of the 11th century, depicting either Thor or Jesus Christ. He is holding an object that is either a Valhallan war hammer, or a crucifix. Who knows? The people who have spent their lives studying the matter don’t. It’s possible no one ever did.

Man arrested over roasted foetuses

Friday, May 18th, 2012

I find black-magic and witchcraft stories out of Africa disturbing.  Out of Asia?  Just as disturbing:

Six human foetuses which had been roasted and covered in gold leaf as part of a black magic ritual have been seized from a British citizen in Bangkok, Thai police said today.

Chow Hok Kuen, 28, who is of Taiwanese origin, was arrested with the grisly haul in the city’s Chinatown yesterday, police said. The corpses had been packed into luggage and were set to be smuggled to Taiwan.

The suspect bought the foetuses several days ago from a Taiwanese man in Thailand for 200,000 baht ($6500) and planned to sell them in Taiwan for up to six times that amount, police said. The origin of the foetuses was unclear.

“He said he planned to sell the foetuses to clients who believe they will make them lucky and rich,” said Colonel Wiwat Kamchamnan of Bangkok police.

The man faces one year in prison and a 2000 baht fine for possession of the foetuses.

What percentage of 7-footers are in the NBA?

Thursday, May 3rd, 2012

What percentage of 7-footers are in the NBA?

An actual accounting of 7-footers, domestic or global, does not exist in any reliable form. National surveys by the Center for Disease Control list no head count or percentile at that height. (Only 5% of adult American males are 6’3? or taller.)…

The curve shaped by the CDC’s available statistics, however, does allow one to estimate the number of American men between the ages of 20 and 40 who are 7 feet or taller: fewer than 70 in all. Which indicates, by further extrapolation, that while the probability of, say, an American between 6’6? and 6’8? being an NBA player today stands at a mere 0.07%, it’s a staggering 17% for someone 7 feet or taller.
