Get out your telescopes

This article indicates that, surprisingly, things are not as bad in one or two villages in the Sunni triangle as one might think:

For the past three years though, there has been little sign of the al Nasseris or other residents of Owja and Tikrit honoring Saddam's tribal largesse by resisting the American presence. Many, indeed, are said to work in U.S. Army bases, something that would earn them a death sentence in other Sunni towns.

"We have good working relations with Saddam's tribe," a local U.S. military spokesman confirmed. "We work on many infrastructure projects together and they support the governor."
U.S. commanders attribute the pacification of Saddam's tribal homelands to the close attention they paid to the area after the invasion. Fearing that it could become an insurgent haven, they established a large military base in Tikrit and made strenuous efforts to hunt down senior regime figures who lived there.


But the real reason for this post is this part of the article:

"Why have there been no big attacks in Owja?" one Sunni from Baghdad asked last week. "They have sold their ground to the occupation for the money, and now they are protecting them. They should feel ashamed because the Americans arrested their relative and their leader."

Such charges are denied by Owja residents, who say they grieve for Saddam as hysterically as the pilgrims flocking to his grave. One day last week, for example, the village was buzzing with claims that Saddam had appeared as the Man in the Moon the night before.

Uh oh

From The Sunday Times:

ISRAEL has drawn up secret plans to destroy Iran’s uranium enrichment facilities with tactical nuclear weapons.

Two Israeli air force squadrons are training to blow up an Iranian facility using low-yield nuclear “bunker-busters”, according to several Israeli military sources.

The attack would be the first with nuclear weapons since 1945, when the United States dropped atomic bombs on Hiroshima and Nagasaki. The Israeli weapons would each have a force equivalent to one-fifteenth of the Hiroshima bomb.

One good thing about such a plan, from the US point of view, is that if the nuclear "bunker busters" are actually made by Israel, this may deflect some of the blame for the attack from America.

Still, any use of nuclear weapon pre-emptively is a big step for a nation.

Those clever Japanese

From an interesting article in the IHT about how good Japan is at conserving energy:

Japan's population and economy are each about 40 percent as large as that of the United States, yet in 2004 it consumed less than a quarter as much energy as America did, according to the International Energy Agency, which is based in Paris.

On a per-capita basis, that means Japan consumed the energy equivalent of 2.8 million tons of oil per person in 2004, in contrast to 5.4 million tons per American. Germany, another energy- conscious country, used 3.2 million tons per person.

I guess the fact that the Japanese would have to have some of the smallest house/apartment sizes in the world, and live mostly in very high density urban areas, has something to do with this. Even so, it is quite cold in many parts in winter, unlike much of Australia, for example.

The other thing I did not know was that fuel cells can be purchased there (at heavy government subsidy) to generate electricity for the home:

One way has been a subsidy of about $51,000 per home fuel cell. This allowed Kimura to buy his cell last year for about $9,000, far below production cost. His cell, which generates 1 kilowatt per hour, provides just under half of his household's electricity, and has cut his electricity bill by the same amount, he said.

The device converts natural gas into hydrogen, which the fuel cell then uses to generate electricity. Heat released by the process is used to warm water.

The first two fuel cells were installed in the prime minister's residence in April 2005. Since then, 1,300 have been sold, according to the Trade and Industry Ministry. The ministry forecasts that as sales pick up, production cost will fall to about $5,000 by decade's end.

That's pretty impressive.

Can we stop talking about it yet?

It's good to see that the media is finding giving the fallout from the hanging a bit of a rest, although today many are running with the Egyptian's president's comments about Saddam becoming a "martyr".

Let's face it, he would been have treated as such by a large number of Arabs regardless of the exact circumstances of the last few minutes of his life. Denying him an (alleged) martyrdom completely, by letting him stay in a comfy European jail during the incredibly slow trial process of the international tribunal, ran the big risk that the Iraqi and Arab media would never have tired of showing him grandstanding in court and encouraging insurgency in his country. It was not a risk worth taking.

It is also interesting that the media does not make much fuss about the actual reaction in Iraq and elsewhere, in terms of violence, being rather muted in the last week. I would have predicted a surge, then a tapering off, and I guess that may still happen. But I still expect that the problems caused by his execution will not be as dire as the critics have predicted.

Shades of "A Clockwork Orange"

I missed reading this article by Richard Dawkins earlier this week. Saddam should not have been hanged, argues Dawkins, he should have been kept alive for scientific study.

Dawkins takes the anti-capital punishment line that would you expect (not that there is anything wrong with that, generally.) He generously allows this:

If President Bush and British Prime Minister Tony Blair are eventually put on trial for war crimes, I shall not be among those pressing for them to be hanged.

Dawkins goes on to write:

...the most important research in which a living Saddam Hussein could have helped is psychological. Most people can't even come close to understanding how any man could be so cruel as Hitler or Hussein, or how such transparently evil monsters could secure sufficient support to take over an entire country.

What were the formative influences on these men? Was it something in their childhood that turned them bad? In their genes? In their testosterone levels? Could the danger have been nipped in the bud by an alert psychiatrist? How would Hitler or Hussein have responded to a different style of education? We don't have a clear answer to these questions. We need to do the research.

Is Dawkins really serious here, or just seeking publicity? The objections are so obvious, but I will list them anyway:

* Most psychological research surely requires the co-operation of the subject, and who says Saddam would ever have agreed to it? If he did not agree, would it have been OK to force him to undergo brain scans, blood tests, etc. Should he just have been filmed 24 hours a day and had conversations secretly recorded? If he is true to his liberal principles, Dawkins would have to admit that if Saddam didn't co-operate, nothing useful could be done.

* Even if he did co-operate, who could believe his own version of his life and influences anyway? There is every reason to suspect that Saddam was not particularly good at reliable self assessment or insight, as are sociopaths everywhere. We don't need to study another one to tell us that.

* Dawkins' idea that everything in evil behaviour is reducible to scientific explanation leads to the idea that criminals should be "cured" rather than punished for wrongdoing. Such a view, with its de-emphasis on free will, is actually dehumanising, despite its (apparent) good intentions.

Silly uses for your robot suit

The Japan Times has an article about the creator of the HAL suit, which had some publicity a year or so ago and looks like this:


The suit, which may be commercially available sometime, is meant to give additional strength to those who need it. But its creator has another idea for its use:

....our robots can be used in the field of entertainment. For instance, by having HAL wearers also wear head-mounted displays, they can watch somebody walking through deep snow and, by having HAL put pressure on their legs, they can feel the sensation themselves. Or we can create a situation where you might be watching a movie at home with a head-mounted display and a HAL suit on, then feel your right leg suddenly being harshly pulled just as Sadako (a creepy character in the horror movie "Ring") is grabbing someone's right leg in the film!

So, for those of you who don't already jump enough at surprises in scary movies, here's a possible answer. It sure is some trivial use for expensive technology.

Of course, what all boys long to see is cyborg soldiers in battle. That would be cool.

The black hole in Ireland

New Scientist's Christmas issue ran an interesting story about a physicist who thinks that a historical report of a "ball lightning" type phenomena seen by one man in Ireland in 1868 may have actually been caused by a tiny black hole. Full access to the article is not (yet) available on line, but sometimes New Scientist drops the restriction after a couple of weeks. I had to buy the paper issue.

The report in question is intriguing, because it involved the ball lightning apparently carving a trench in the soil/peat it passed over. I have read about ball lightning before, but had never heard of this effect. The article claims that the damage alleged caused is still visible at the site.

The idea that a small primordial black hole (left over from the big bang) was at the heart of the glowing ball assumes that Hawking radiation does not exist; a point which very, very few scientists seem willing to seriously consider as a possibility. (I don't have time to provide the links right now, but go search this blog for "black holes" and you'll see what I mean.)

It seems clear that a lack of a quantum gravity theory means there is a good degree of uncertainty about the finer points of how HR would work, particularly at the end of the evaporation process. That an evaporating micro black hole may leave a remnant, the exact nature of which I have not really seen explained clearly, seems a possibility still very much up in the air.

The black hole - ball lightning theory also has to come up with some fancy footwork to explain why the ball lightning bounced along the ground, and didn't eat up the earth by now. (In fact, the article does not mention at all what the physicist thinks was the eventual fate of the black hole in question.)

Still, it is interesting and potentially relevant to the issue of possible danger from the LHC.

Gore gored

If you happen to think that Gore Vidal is a self-important bore, you will find plenty of support for your view in an article in Salon (of all places.)

Never trust a President without creases

Tigerhawk points out one of the more ridiculous recent posts in Huffington Post. It really puzzles me as to why that site has any credibility at all.

Left, right, etc

Janet Albrechtsen ends a column with this:

So I'll leave you with a larger but somewhat cheeky hypothesis. Left-wing politics is essentially an emotional, instinctive utopian kind of world peopled by romantics and dreamers. Conservatism is, on the other hand, more rational, analytical and pragmatic. That is why creative types tend to come from the Left. Right-wingers, by contrast, have real jobs.

Of course, calling it "somewhat cheeky" indicates that she's hardly likely to consider it entirely defensible. But still it attracts a lot of criticism from the left-y side.

What do I think? Well, that the modern "creative type" is much more commonly left leaning is surely true, isn't it? (Why that is so is not entirely clear to me, nor is why it seems especially true of the last 40 years or so.) I would have also thought that Marxism was clearly utopian in nature, and a matter of faith masked as science. There is surely still an element of utopianism that runs through the Left.

But the issue of the rational/emotional divide is more complicated than Janet's take. Modern social conservatives of a religious bent (like me) understand the emotional appeal of the old faith, and regret that it has less influence on society. On the other side, there is often the unreflective atheistic utilitarianism of modern ethics, which prides itself as more rational than anything that is partly based on faith and mystery.

Of course, it is not as if mainstream Christian religious ethics doesn't employ rational argument too. (Pope Benedict reminded the world of this recently.) One of the most frustrating things about arguing with the irreligous Left can be their attitude that their conclusions are self-evidently more rational than that of those who have a religious influence. In fact, the different conclusions may arise more from the varience in fundamental assumptions about human nature and reality, and these are really matters of faith (or at least unproveable) for either side.

Someone else has probably explained this better than I can...

Who reads who

Over at Andrew Norton's blog a couple of weeks ago, he mentioned how bloggers' audiences are mainly people who already agree with them. I made this comment:

Andrew, yes the “echo chamber” function of blogs is clear, but I have a theory that it is worse on the Left than the Right. This is because many on the modern Left (particularly the idealistic youth) consider opinions different from their own as both irrational and morally defective, and therefore spending much time reading such opinions in blogs is like dabbling in evil (if they believed in evil). It often just gets them so annoyed they cannot continue reading.

As evidence in support, have a look at this post at Blogocracy. Turns out Tim Dunlop and his regular band of not so merry men (he does seem to attract few female commenters) find the moderate Right opinions of Gerard Henderson so annoying they can't bear to even read him anymore. As one commenter also notes, it's quite a hoot that Dunlop calls Henderson "predictable".

Henderson's other great benefit over Dunlop is brevity.

Musical instruments with a difference

Never having been to Nepal, I had not heard before about this surprising aspect of its version of Buddhism (from a recent travel article in The Times):

Rosa had been asked to take this particular damaru back to England for some Buddhist friends, and was understandably nervous about it. The hand drum was just as she had described. It was made out of human skulls — children’s skulls, to be precise. Over the highly polished craniums was stretched a thin membrane of human skin.

“One skull is female, the other is male,” she explained. “It symbolises the union of wisdom and compassion. It’s very powerful. If you get one made out of babies’ skulls, that’s even better — something to do with the energy flowing through the opening in the fontanelles.”...

The shops around Boudhanath are full of similar objects. In one, I was shown a selection of skull offering bowls; in another, half a dozen trumpets made from women’s thigh bones. Dusting one off, the shopkeeper put the hip joint to his lips and blew, making a noise like a hunting horn.

Rather disturbing to a Western mind, especially those instruments made out of kids or babies skulls.

Henderson on the hanging

Gerard Henderson's SMH column on the reaction to the hanging of Saddam is good. The best paragraph answers those who claim it is hypocrisy for the Australian government to only sometimes diplomatically complain about death penalties:

The Prime Minister's stance ignited criticism from the civil liberties lobby. Lex Lasry, QC, said this position "compromises our international standards" since "we cannot pick and choose on the death penalty".

But there is nothing inconsistent in attempting to obtain a reprieve for an Australian convicted of a serious drug offence in, say, Singapore and declining to put pressure on a democratic government intent on executing a mass murderer whose supporters form part of an extant murderous insurgency and who had been convicted in a public trial.

Death by Mochi - 2007 edition

The annual Japanese New Year mochi toll is in:

TOKYO — Four men choked to death on Monday and Tuesday in Tokyo, Niigata and Ibaraki prefectures, and seven others in the capital became critically ill after choking on mochi rice cakes, a traditional New Year's food in Japan, police and firefighters said.

A 68-year-old man in Tokyo's Fuchu and a 76-year-old man in the capital's Sumida Ward died Tuesday after choking on the rice cakes, while a 74-year-old man in Ojiya, Niigata Prefecture, and an 80-year-old man in Chikusei, Ibaraki Prefecture, died likewise on Monday, they said. In Tokyo, a total of 16 people ranging in age from 65 to 91 were hospitalized due to choking on rice cakes on Monday and Tuesday, and two of them died and seven lost consciousness and were in a serious condition, the Tokyo Fire Department said.

A New Year's Day Miscellany

Happy New Year everyone.

There's not much obvious to post about today. The Sydney Morning Herald gets off to a bad start by running an article by Bob Ellis which, even by his standards, appears to be written after an exceptionally long night on the claret. (It's about the death of Saddam, who he seems to think went to the gallows in a noble fashion, unlike how he imagines George W would behave.) It is truly a puerile read.

As for the future, reviewing psychic predictions for the year just gone is always a laugh. Have a look at this list of reader predictions from About.com. A more comprehensive list of inaccurate prophecy may be very hard to find. I like this one:

A book will be published in 2006 that completely explains existence. By doing so it will prove the world wrong on a Copernicus (flat-world) scale. The presentation will be that which will put traditional values on the defensive using simple logic that cannot be refuted.

How about this cryptic one in the "entertainment" section:

Harry Potter strikes again and again.

And under the "surprise predictions" category:

The Elizabethan collar will come back in style along with the poofy sleeves.

On another topic, I will be looking out for the figures on this New Year's Japanese mochi chocking deaths with interest. (It's a more interesting hobby than following the media obsession with holiday road accidents in Australia.)

Finally, the British Medical Journal has a more or less serious (I think) article that contains everything you ever wanted to know about sword swallowing. (And yes, it is often medically dangerous.) This extract about you learn how to do it is particularly interesting:

Some respondents swallowed a sword easily, but mastery for most required daily practice over months or years. The gag reflex is desensitised, sometimes by repeatedly putting fingers down the throat, but other objects are used including spoons, paint brushes, knitting needles, and plastic tubes before the swallower commonly progresses to a bent wire coat hanger. The
performer must then learn to align a sword with the upper oesophageal sphincter with the neck hyperextended. The next step requires relaxation of the pharynx and oesophagus and particularly the horizontal fibres of cricopharyngeus, which are not usually under voluntary control.

The more mysterious question of why anyone still bothers to learn this is not addressed.

On the death of Saddam

Long time readers would know that I agree with Roger Simon's point. Captain's Quarters' take on the execution is fair enough too.

I note that some of the critics of executing Saddam talk about how it will not help Iraqi "reconciliation". Well, it seems to me that the main example of successful national reconciliation is South Africa, but the history of that country, and the circumstances of the change in power there, are vastly different from what has happened in Iraq. (And who is the equivalent national hero to Mandela who would make a similar kind of reconciliation process in Iraq even vaguely possible?) It also seems rather improbable to me, although I stand to be corrected, that Iraqis don't already know enough of the genocidal actions of Saddam in relation to the Kurds.

Somewhat surprisingly, The Guardian's obituary is the one that seems to go into the most detail about Saddam's evil character.

As for those from the West who say "Bush and Blair should be next", they are the people who really worry me for the future of a sane world.

Waiting for the apology

A few weeks ago the Fairfax press, and indeed the Murdoch press, both ran with a story that that John Howard and Alexander Downer had "distorted" advice to them when using the phrase "biological agent" to describe a white powder that had been sent to the Indonesian embassy. The alleged reason for this was because documents obtained under FOI from ACT Pathology and the Federal Police never used the phrase. Have a look at Tim Dunlop's Blogocracy post about this, where he ends with this:

You simply can’t take at face value a word that comes out of their mouths. It’s about time the media stopped reporting this tendency as ‘smart politics’ and started calling it what it is, dishonesty.

For those who love reading stupid Howard conspiracy theories, read some of the comments to that post too.

Today, the Sydney Morning Herald points this out:

ADVICE relied on by the Prime Minister to describe flour sent to the Indonesian embassy last year as a "biological agent" appears to have originated in the ACT Emergency Services Authority, according to documents just released.

Unsigned situation reports produced by the authority's Emergency Co-ordination Centre on June 1 last year, the day the powder was found at the embassy, say the material "has been positively identified as a biological agent", that further testing was under way and a result was likely to take 24 to 48 hours.

Yet, according to the original report in The Age:

Staff at ACT Health and ACT Emergency Services were stunned when the Government called the powder a biological agent.

Obviously, whoever The Age spoke to at ACT Emergency Services did not know what was in its own situation reports. Did the reporter really speak to anyone of significance there?

Any sign of an apology from the press over this? Of course not. From further down today's SMH story:

Earlier this month Mr Howard and the Foreign Affairs Minister, Alexander Downer, denied a Herald report that they had distorted test results on the material. Mr Howard said he and Mr Downer had quoted directly from advice provided by the Protective Security Co-ordination Centre saying it had tested positive as a biological agent and that further testing would need to be carried out to determine what the substance actually was.

The Government has not released the full protective security advice but the new documents show the centre was liaising with the Emergency Co-ordination Centre, suggesting their reports were probably used in the protective security advice to the Commonwealth Government.

There seems to be no suggestion that the Emergency Co-ordination Centre's situation reports picked up the phrase "biological agent" from John Howard himself. (The SMH report could easily have clarified this by telling us the time of the first "situation report" was issued. If it was prior to Howard's press conference, there is no wriggle room left for conspiracy theorising at all.)

But basically, it seems to me that the SMH story comes as close as they can bring themselves to saying they were wrong, and Howard and Downer's version was completely correct, without actually saying it.

Today's story tries to salvage some criticism of the government because:

The biological terrorism scare continued until June 2, when the Government announced the powder was not harmful.

This was despite an email from the federal police national manager of intelligence, Grant Wardlaw, sent to the office of the Justice Minister, Chris Ellison, at 6.35pm on June 1 making clear there was no confirmed evidence the powder was a harmful substance. Dr Wardlaw said the powder had tested positive to gram bacilli.

"Gram bacilli is a commonly occurring bacteria. If spores of this bacteria are found to be growing in the substance this raises the level of potential risk.

"Information to date is that no spores have been identified by pathology," he said.

So, it is still some sort of scandal that the "scare" (which presumably only affected anyone working at the Indonesian embassy in the first place) was in place for about 24 hours? Talk about trying to make a story out of nothing.

And by the way, don't bother looking for this story in The Age today. It doesn't even appear there at all. News Limited doesn't seem to have run it either.

This is why our press is so respected.

Speaking of the weather...

Maybe it is just that by mid-life, really hot weather starts to annoy everyone much more than it did when they were younger. Whatever the reason, it has seemed to me that most Christmas Days, and summers generally, in Brisbane over the last 6 years or so have been unbearably hot and uncomfortable. So I have been delighted that this summer has been so unseasonably cool. All those holiday makers on the Gold and Sunshine Coasts might be regretting paying $2,000 and more for a week by the beach, though.

Anyway, while browsing the web looking for more details about the Federation drought of 100 years ago (it's not so easy to find,) I stumbled onto this page from the Australian Bureau of Statistics about Australian deserts. They can be a lot hotter than I thought:

The most famous long hot spell in Australian history was that at Marble Bar in the summer of 1923-24, when there were 160 consecutive days above 37.8°C (100 degrees Fahrenheit). Even in those areas where the most extreme heat is rare, there are many hot days; for example, at Giles, where the all-time record high is a relatively modest 44.8°C, there are an average of 100 days per year of 35°C or above, including 69 in succession during the summer of 1964-65.

While I am not exactly a global warming sceptic, it is very important to realise how bad Australian weather has been in the past before you start to talk about how bad it is at the present.

What you may have missed in my absence

Here's a list of some interesting stories from the last week:

Let me do the panicking for you: If the Large Hadron Collider or an asteroid does not get humanity first, a series of supervolcanoes will make life miserable enough sooner or later again anyway. Here's a Christmas Day story that did not attract much attention:

Auckland University scientists have revealed that eruptions of supervolcanoes powerful enough to change the climate and cause mass-extinction can be worse than previously thought...

Such large eruptions of greater than 100 cubic kilometres of magma are generally rare and random events worldwide.

But geologist Darren Gravley of Auckland University and his colleagues have shown that one of the largest supervolcano eruptions on record, at Taupo 250,000 years ago, was twice as big as previously thought.

They have published in the Bulletin of the Geological Society of America evidence that the eruption in the Taupo Volcanic Zone was actually two supervolcanoes 30km apart which erupted within days or weeks of each other.

What's worse:

Last year, other research at Taupo - on the more recent Taupo supervolcano of only 26,500 years ago - changed accepted theories that it takes hundreds of thousands of years for the reservoir of molten rock, or magma, beneath a supervolcano to build up to an eruption.

They showed the period between super-eruptions can be much shorter, perhaps a few tens of thousands of years.

Dr Bruce Charlier, from Britain's Open University, showed the build-up at Taupo was no more than 40,000 years - a relatively short time period in geological terms.

A happy pre-Christmas report: having a drink before your head injury is a good idea. The trick is in making sure your drink does not cause you to have the injury in the first place.

Everyone's favourite cat borne disease gets noticed again: The Australian media noticed a toxoplasma story that talked about possible behavioural changes in people infected with it. (Funny, this was covered thoroughly in blogs, including mine, in August.)

But in fact, Science Daily notes recently that has been a cluster of new papers about toxoplasma. This part of their report was interesting:

Toxoplasmosis is a disease caused by the parasite Toxoplasma gondii. Symptoms usually appear only in people with weakened immune systems, but on rare occasions, healthy people suffer serious eye and central nervous system problems from toxoplasmosis. Their babies can have birth defects. White said toxoplasmosis also may be linked to some cases of schizophrenia and bipolar disease. It can kill livestock and has devastated efforts to restore sea otters near Monterey, Calif. Because it's common, yet complex, toxoplasmosis is a potential weapon for bioterrorists.

Bioterrorism, when nearly half the world has it already? Sounds a little unlikely. But then again, it they gathered a ton of cat poo and put it in the local water supply, I guess it would put me off drinking water for some time.

Hitchens goes to Iraq

There's a short Slate piece by Hitchens about a recent trip to Iraq. Good reading, as always.
