RoboCop, PhD

Thursday, January 25th, 2007

If you’ve been watching the History Channel’s Engineering an Empire series, which I recommend, then you know that Peter Weller, who hosts it, is on his way to becoming RoboCop, PhD:

He spent much of the past two decades in Italy and, on a lark, enrolled in classes at the Syracuse University program in Florence. He soon discovered he had a thing for the aqueducts of long-dead civilizations, and now he’s working toward a PhD in Italian Renaissance art history from UCLA. This is no vanity degree; Weller teaches courses, writes papers, and is doggedly climbing the academic ladder. Buckaroo Banzai, the polymath who was arguably Weller’s most famous character — acclaimed neurosurgeon, race car driver, particle physicist, and, of course, rock star — would be proud. “I’ve always followed my passions,” Weller says, “even when it didn’t seem to make much sense.”

It’s hard to imagine what freshmen think when they wander into Professor Banzai’s lecture hall. Weller reports that he loses a lot of students after the first class. “They thought they were going to get the easy A from old RoboCop,” he says with a laugh. The 450-page course reader tells them otherwise. Those who stay get a view into Weller’s two worlds. For example, his class at Syracuse on Hollywood and the Roman Empire requires watching toga-and-sandal epics (Ben Hur and The Last Temptation of Christ among them) and reading primary-source Roman authors in an attempt to reconcile big-screen Rome with the real thing. “The Romans were an unbelievably complex people, and we are an unbelievably complex people,” Weller says. “We can learn so much about why things are the way they are by looking at what they did.” He goes on to explain how the absence of the concept of zero in Greek antiquity laid the foundation for Western philosophical thought.

Giant lions and kangaroos once roamed Australia

Thursday, January 25th, 2007

Giant lions and kangaroos once roamed Australia — but, apparently, they didn’t fit on the Ark:

Marsupial lions, kangaroos as tall as trucks and wombats the size of a rhinoceros roamed Australia’s outback before being killed off by fires lit by arriving humans, scientists said on Thursday.

The giant animals lived in the arid Nullarbor Desert around 400,000 years ago, but died out around 50,000 years ago, relatively shortly after the arrival of human settlers, according to new fossil skeletons found in caves.

Fossilized remains were uncovered almost intact in a series of three deep caves in the center of the Nullarbor desert — east of the west coast city of Perth — in October 2002. “Three subsequent expeditions produced hundreds of fossils so well-preserved that they constitute a veritable “Rosetta Stone for Ice-Age Australia,” expedition leader Gavin Prideaux said of the find, detailed in the latest edition of the journal Nature.

The team discovered 69 species of mammals, birds and reptiles, including eight new species of kangaroo, some standing up to 3 meters (9 feet) tall.

Protected from wind and rain, and undisturbed due to their remote location, the remains of the mega-beasts are in near-perfect condition, including the first-ever complete skeleton of a marsupial lion, Thylacoleo carnifex.

“Unwary animals bounding around in the case of kangaroos, or running around in the case of marsupial lions and wombats, fell down these holes, as presumably most were nocturnal. It’s very difficult to see a small opening on a flat surface at night,” Prideaux said.

Research into the fossils challenges recent claims that Australia’s megafauna were killed off by climate change, pointing the finger instead at fires, probably lit by the first human settlers who transformed the fragile landscape.

The lands inhabited by the megafauna once supported flowers, tall trees and shrubs. But isotopes extracted from skeletal enamels show the climate was hot and arid, similar to today.

The plants, the scientists said, were highly sensitive to so-called fire-stick farming, where lands were deliberately cleared by fires to encourage re-growth.

“Australian megafauna could take all that nature could throw at them for half-a-million years, without succumbing,” said Richard Roberts, a geochronologist at the University of Wollongong. “It was only when people arrived that they vanished.”

French Lessons

Thursday, January 25th, 2007

In French Lessons, Alvaro Vargas Llosa looks at the lessons of the Battle of Algiers:

What lesson from that conflict is relevant today? The paramount lesson seems this: “First-world” armies and “third-world” guerrillas have different notions of time and space, and therefore of what constitutes defeat and victory. A “first-world” army can defeat “first-world” guerrillas and a “third-world” army can defeat “third-world” guerrillas because in both cases the army and the enemy operate under similar notions of time and space. The Italian security forces were able to defeat the Red Brigades, just as Germany’s security forces were able to defeat the Baader-Meinhof Gang, because they were at war with each other under similar time and space horizons. Equally, Alberto Fujimori’s dictatorship was able to defeat the Shining Path in Peru in the 1990s and Venezuela’s Romulo Betancourt destroyed the Castro-inspired guerrillas in the 1960s because the warring sides shared a common idea of where and when they were fighting. That is not to say that in all such cases the army will triumph. Castro’s victory in 1959 proves that the opposite can happen. But as long as the established power commands enough civilian support, which is usually the case against a terrorist insurgence, the security apparatus enjoys a big advantage.

In Algeria, the occupying force’s notion of space was purely physical and military: The French paratroopers thought that as long as they smoked the terrorists out of the Casbah — the Muslim quarter in Algiers — they would win. The insurgents’ notion of space was historic and civilian: As long as they gave the oppressed masses a sense of the anomaly that the century-old French presence in their land constituted, the liberation struggle would go on. The French army’s notion of time was narrow, while the insurgents had a broad time horizon. The French won the battle of Algiers but in 1962 they had to give up the colony.

It was not a matter of how many troops there were on the ground. In 1960, France had 400,000 troops in Algeria — not far from the number the U.S. poured into Vietnam. And the moral legitimacy of the insurgents is not defined by the methods they employ, but by how close they are to the population and how effectively they help shape the people’s perception of the enemy. Algeria’s insurgents were tyrants, and once they liberated their nation they established a dictatorship. But the fact that they were perceived as legitimate by the civilian population — precisely because their notion of space and time attached them to that population and the country’s history — meant that the occupiers ended up losing the war whose every battle they had won.

Don’t you know your left from your right?

Thursday, January 25th, 2007

In the second part of Don’t you know your left from your right?, Nick Cohen explores “the disgrace of the anti-war movement” that had a million people marching through London to oppose the overthrow of a fascist regime:

Journalists wondered whether the Americans were puffing up Zarqawi’s role in the violence — as a foreigner he was a convenient enemy — but they couldn’t deny the ferocity of the terror. Like Stalin, Pol Pot and Slobodan Milosevic, they went for the professors and technicians who could make a democratic Iraq work. They murdered Sergio Vieira de Mello, one of the United Nations’s bravest officials, and his colleagues; Red Cross workers, politicians, journalists and thousands upon thousands of Iraqis who happened to be in the wrong church or Shia mosque.

How hard was it for opponents of the war to be against that? Unbelievably hard, it turned out. The anti-war movement disgraced itself not because it was against the war in Iraq, but because it could not oppose the counter-revolution once the war was over. A principled left that still had life in it and a liberalism that meant what it said might have remained ferociously critical of the American and British governments while offering support to Iraqis who wanted the freedoms they enjoyed.

Japanese marine park captures rare shark on film

Wednesday, January 24th, 2007

Japanese marine park captures rare shark on film — before it dies:

A species of shark rarely seen alive because its natural habitat is 600 meters (2,000 ft) or more under the sea was captured on film by staff at a Japanese marine park this week.

The Awashima Marine Park in Shizuoka, south of Tokyo, was alerted by a fisherman at a nearby port on Sunday that he had spotted an odd-looking eel-like creature with a mouthful of needle-sharp teeth.

Marine park staff caught the 1.6 meter (5 ft) long creature, which they identified as a female frilled shark, sometimes referred to as a “living fossil” because it is a primitive species that has changed little since prehistoric times.

The shark appeared to be in poor condition when park staff moved it to a seawater pool where they filmed it swimming and opening its jaws.

“We believe moving pictures of a live specimen are extremely rare,” said an official at the park. “They live between 600 and 1,000 meters under the water, which is deeper than humans can go.”

“We think it may have come close to the surface because it was sick, or else it was weakened because it was in shallow waters,” the official said.

The shark died a few hours after being caught.

Frilled sharks, which feed on other sharks and sea creatures, are sometimes caught in the nets of trawlers but are rarely seen alive.

Lasersharking

Wednesday, January 24th, 2007

Lasersharking is combining two things that are cool on their own to make something stupid.

As someone named Jack Spencer said, in obvious reference to Austin Powers, “If a gamer had made Jaws it would not have been a shark but a shark with a laser on its head.”

The postwar photographs that British authorities tried to keep hidden

Wednesday, January 24th, 2007

The postwar photographs that British authorities tried to keep hidden have finally come out — or at least some of them have:

For almost 60 years, the evidence of Britain’s clandestine torture programme in postwar Germany has lain hidden in the government’s files. Harrowing photographs of young men who had survived being systematically starved, as well as beaten, deprived of sleep and exposed to extreme cold, were considered too shocking to be seen.

As one minister of the day wrote, as few people as possible should be aware that British authorities had treated prisoners “in a manner reminiscent of the German concentration camps”.

Many other photographs known to have been taken have vanished from the archives, and even this year some government officials were arguing that none should be published.

The pictures show suspected communists who were tortured in an attempt to gather information about Soviet military intentions and intelligence methods at a time when some British officials were convinced that a third world war was only months away.

Others interrogated at the same prison, at Bad Nenndorf, near Hanover, included Nazis, prominent German industrialists of the Hitler era, and former members of the SS.

At least two men suspected of being communists were starved to death, at least one was beaten to death, others suffered serious illness or injuries, and many lost toes to frostbite.

To the Shores of Tripoli

Tuesday, January 23rd, 2007

The title, To the Shores of Tripoli, gives away the punchline, but I enjoyed this article, which cites Sam Ser at the Jerusalem Post, who “retells the story from the vantage of Michael Orren’s book, Power, Faith, and Fantasy: America in the Middle East: 1776 to the Present“:

The meeting in London was doomed from the outset. The Arab strongman’s envoy held all the cards — three craft had already been hijacked, their passengers and crew held hostage in an inhospitable and almost unreachable land. The American ambassador knew the ransom demand would be high, but even he could not have imagined just how exorbitant it would be. To meet it would require one-tenth of America’s annual budget.

Lest the adventurous Yanks dare to contemplate a military attack to rescue their captured comrades, Abd al-Rahman al-Ajar provided a most unpleasant revelation: the Koran declares that any nation that does not bow to the authority of the Muslims is sinful, and it is the right and duty of Muslims to make war upon it and take prisoner any of its people they may find. Further, any Muslim slain in battle against such an enemy would be promised a place in Paradise.

“We ought not to fight them at all unless we determine to fight them forever,” the furious but helpless ambassador relayed to his government. Congress would authorize no such fight, however, and voted instead to pay the ransom.

Wretchard adds some important commentary:

It’s now forgotten that capitulation didn’t work. Simply didn’t work. The Barbary Pirates raised their demands until the Pashas were taking nearly 20 per cent of Federal Revenue. But in the beginning the policy of appeasement seemed perfectly. The initial extortion demand of $70,000 was far smaller than the astronomical $2 million dollars requested by Thomas Jefferson to build a Navy. In the end it proved cheaper to crush them.

Here’s a bit of historical trivia that caught my eye:

Before he revised it in the War of 1812, Francis Scott Key’s “Star-Bangled Banner” — which would become the American national anthem — described “turbaned heads bowed” to the “brow of the brave.”

Springtime for Ethanol

Springtime for Ethanol notes that the fashionable alternative fuel “yields a third less energy than petroleum-based gasoline and still relies on a federal subsidy of 51 cents a gallon to remain competitive.”

I like traffic lights, but only when they’re dismantled

Tuesday, January 23rd, 2007

Martin Cassini says, I like traffic lights, but only when they’re dismantled:

Think of all the hours in your life wasted as your car journey is stopped by lights to let non-existent traffic through. And then ask yourself this: who is the better judge of when it’s safe to go — you, the driver at the time and place, or lights programmed by an absent regulator? Traffic lights exist as a “cure” for a man-made malady — the misconceived priority rule. This rule confers superior rights on main-road traffic at the expense of minor-road traffic and pedestrians. To interrupt the priority streams, lights are “needed”.

Before 1929 when the priority rule came into force, a sort of first-come, first-served rule prevailed. All road users had equal rights, so a motorist arriving at a junction gave way to anyone who had arrived first, even the humble pedestrian. Motorists had a simple responsibility for avoiding collisions, and a duty of care to other road users.

In other walks of life the common-law principle of single queueing applies, but the law of the road, based on the priority rule that licenses queue-jumping and aggression, creates battlegrounds where we have to fight for gaps and green time.

But when lights are out of action — when we’re free of external controls and allowed to use our own judgment — peaceful anarchy breaks out. We approach slowly and filter in turn. Courtesy thrives and congestion dissolves. And when the lights start working again, congestion returns.

Poke in the eye saves shark victim

Tuesday, January 23rd, 2007

I am a sucker for shark-attack stories. From Poke in the eye saves shark victim:

Eric Nerhus, a 41-year-old professional diver is in a serious but stable condition, and is expected to survive, after being half swallowed by the three-metre shark at Cape Howe, near Eden, on the NSW south coast, about 9.30am today.

The shark seized Mr Nerhus by the head, crushing his face mask inwards and breaking his nose, said friend and fellow diver Dennis Luobikis.

“He was actually bitten by the head down, the shark swallowed his head,” Mr Luobikis said.

Taking a second bite, the white pointer clenched its jaws around his torso, tearing deep lacerations in either side of his body.

Against the odds, Mr Nerhus, a well-known local diver of more than five years’ experience, managed to free himself from the shark’s jaws, and was pulled back aboard the boat by his son.

Two other young divers in a nearby boat rendered immediate first aid and one radioed his father, who was flying overhead in a spotter plane, to call for emergency help.

I hadn’t heard the great white referred to as a white pointer before. By the way, a three-meter great white is fairly small, as far as great whites go.

Why the world’s greatest stock picker stopped picking stocks

Tuesday, January 23rd, 2007

Henry Blodget explains why the world’s greatest stock picker stopped picking stocks:

First, in the seven decades since [Benjamin] Graham wrote Security Analysis, the stock market has gone from being a playground for amateurs to a battlefield dominated by full-time professionals. One result is that pricing errors that once might have gone unnoticed for months in Graham’s day are now discovered and exploited instantly. Second, the amount of information available about the most obscure stock today dwarfs what was available about even the bellwethers a half-century ago, making it harder to dig up information that other investors don’t know. The moment the information is released, moreover, it is dissected, discussed, and debated by thousands of analysts, until most reasonable conclusions that can be drawn from it have been. Today’s technology also allows even part-time investors to screen tens of thousands of stocks in dozens of markets in the time it would have taken a Graham-era analyst to compute the “net current assets” of a single company.

Third, inside information that used to be quite valuable is now illegal to trade on. And, finally, the establishment of research centers such as the Center for Research in Security Prices (CSRP) has allowed analysts to study markets and investing in ways that the young Benjamin Graham could only have dreamed of — and, in so doing, to assemble a body of knowledge that makes much of the “investment wisdom” of the early 20th century seem as primitive and unscientific as bloodletting.

Requiem for the Magic Bullets

Tuesday, January 23rd, 2007

Requiem for the Magic Bullets describes the rise and fall of antibiotics:

The golden age of antibiotics began in 1944 with the widespread use of penicillin in Europe, which saved many thousands of lives during World War II. But the first sign that this new era of easily treatable bacterial infections would not last appeared just a couple of years later, with the emergence of penicillin-resistant strains of Staphylococcus aureus, a bacterium responsible for a wide variety of ailments, from skin infections to fatal pneumonia.

By 1950, 40 percent of the staph strains in hospitals had already become immune to the drug. Now a form of staph known as methicillin-resistant Staph aureus, or MRSA, which is resistant to nearly every known antibiotic, is responsible for the majority of tens of thousands of deaths a year from infections picked up in U.S. hospitals alone.
[...]
Developing and testing a new antibiotic can take 10 years and cost more than $800 million, and pharmaceutical companies face an ever-changing maze of federal regulations to successfully bring a product to market. Several major drug manufacturers — including Abbott Laboratories and Eli Lilly and Company — have either drastically reduced their development of new antibiotics or given up on antimicrobial R&D altogether as an unprofitable enterprise.

The fact that antibiotics are usually prescribed for only a short time — seven to 14 days, long enough to beat the infection or fail — makes them unattractive investments. Instead, the big money in Big Pharma is flowing toward the development of lifelong treatments for chronic conditions like diabetes, heart disease, arthritis and HIV infection. Only two truly novel classes of antibiotics have been brought to the marketplace in the past decade.

The Invisible Enemy in Iraq

Tuesday, January 23rd, 2007

The Invisible Enemy in Iraq is a normally innocuous bacterium — Acinetobacter baumannii — that has become resistant to most antibiotics, killed immune-compromised troops after surgery, and spread to the wider healthcare community:

The wounded soldiers were not smuggling bacteria from the desert into military hospitals after all. Instead, they were picking it up there. The evacuation chain itself had become the primary source of infection. By creating the most heroic and efficient means of saving lives in the history of warfare, the Pentagon had accidentally invented a machine for accelerating bacterial evolution and was airlifting the pathogens halfway around the world.

To stem the outbreak at its source, the epicon team proposed sweeping reforms throughout the combat zone. The CSHs had to be run more like real hospitals, with frequent scrub-downs, stringent hand-washing, and HEPA filters to clean the air. The dead tissue surrounding “frag” wounds turned out to be an ideal colonization site for the bugs, so it had to be removed more aggressively up front. “If you don’t have that necrotic tissue, your own innate defenses help keep the wound clean,” says Kim Moran, a tropical-disease specialist who assisted the investigation when she worked at Walter Reed. Wound dressings needed to be changed less often, so bacteria from the hospital environment had less opportunity to get in. And the broad-spectrum antibiotics had to be reserved for the treatment of identified bugs.
