Medieval report

Guess where we went yesterday?

It's a place where men oil themselves and wrestle, while other men watch:


It's a place where walking tree/wood nymph thing-ees wander:



It's where a hell of a lot of people dress up and wander around



and a woman can indulge her favourite past-time: firing replica breach canons, causing much smoke and sound,



while men dress up as old soldiers and hit each other for fun and (sort of) entertainment:

(I would move that crappy video to the centre if I could work out how.)

Yes, it was the Abbey 2010 Medieval Tournament, held just north of Brisbane.

It's been going on for years, but I've never made it there before.

One of the most interesting thing about it was that it made me realise the number of medieval themed club-like groups that must be around, lurking beneath the veneer of normal society. I spoke to one guy who was showing me how to make authentic medieval shoes and asked him: if one has a desire to be a medieval craftsman/soldier/musician, how does one go about finding entry into a group who can teach you how?

It does seem to come down to who you know, and (I suppose) attending these tournament events and begging entry into a quasi-secret society that catches your fancy. Then you too can dress up and yearn for the old (really old) days at least once a year.

Actually, it was all good fun, and next year I plan on attending as Thomas Aquinas.

Starfish Prime revisited

Bad Astronomy linked to a recent NPR story* with video of the 1962 Starfish Prime nuclear explosion in outer space. Interesting.

By the way, I've never been to the NPR news homepage before, but it has a very clean look that appeals.

* This is also, as it happens, how I found an NPR story on an old porn star. Just in case you were wondering.

Career choices of the older but not so wise

This whole stupid “cougar” business has to stop soon, doesn’t it?  NPR reports:

Diana Grandmason is a 50-year-old redhead who once ran an investments business in Florida. Perhaps an unlikely performer in adult films — but until a year and a half ago, she starred in X-rated movies, including Seduced by a Cougar.

Grandmason says she got into the porn business to follow her daughter, Bess Garren.

"Basically, she called me at work and said, 'I'm gonna go do this,' and I said, 'No you're not.' And she said, 'Mom I'm 21, this is a courtesy call, I'm doin' it.' So what choice did I have?" she explains.

But then, she decided to follow Garren.

"Originally it was signing up just so I could accompany her, and then I kinda got sold on the idea myself," Grandmason says.

Geeky hobby success

Amateur metal detecting as a hobby never seems to have taken off in Australia the same way as it did in America or (apparently) Britain. Metal detectors have featured in the ads sections of geeky American science magazines for decades, but here, apart from the occasionally opportunistic aging coin hunter going over the beach sand in the evening, I’ve never noticed them much. Maybe it’s because there is so little history in this country waiting to be discovered. No pirate treasure from the Caribbean is likely to have found its way to the beaches of Coochiemudlo Island*, after all.

Anyhow, in England, the hobby can really pay off. At least for a museum:

The largest single hoard of Roman coins ever found in Britain has been unearthed on a farm near Frome in Somerset.

A total of 52,500 bronze and silver coins dating from the 3rd century AD – including the largest ever found set of coins minted by the self proclaimed emperor Carausius, who lasted seven years before he was murdered by his finance minister – were found by Dave Crisp, a hobby metal detectorist from Devizes, Wiltshire.

Crisp first dug up a fingernail-sized bronze coin only 30cm below the surface. Even though he had never found a hoard before, when he had turned up a dozen coins he stopped digging and called in the experts, who uncovered a pot bellied pottery jar stuffed with the extraordinary collection, all dating from 253 to 293 AD – the year of Carausius's death.

As I said it’s good for museums, not so much benefit for the discoverer:

The archaeologists praised Crisp for calling them in immediately, allowing the context of the find to be recorded meticulously. When a coroner's inquest is held later this month in Somerset, the coins are likely to be declared treasure, which must by law be reported. Somerset county museum hopes to acquire the hoard, which could be worth up to £1m, with the blessing of the British Museum.

Good lines, Richard

My favourite paragraph from Richard Glover’s column today, about prejudices against men:

Why are we accused of not doing our share of the housework? Men are assiduous about this sort of stuff. For example, many Australian men clean out their online browsing history almost every day. Don't thank us; we're just naturally tidy.

My second favourite bit:

What's the story with the ABC and the interminable bonnet dramas on Sunday nights? Is there any Thackeray left? Just how many books did Dickens write? Are five versions of Pride and Prejudice enough, or could we squeeze in one more? Oh, oh, Mr Darcy, oh, oh. Really, how much more of this stuff are we expected to endure?

Pathetic weaklings

Health alert in high temperatures and humidity - Home News, UK - The Independent

I love the way the British go into a heat fearing panic as soon as temperatures reach some startling figure, like 30 degrees.

But wait - what if the minimum temperature never goes below 20! Panic!:

The first heat-health alert of the summer was in force today as parts of the country faced several days - and nights - of sweltering conditions

Highs of up to 31C (87.8F) are expected as temperatures peak across East Anglia and south-east England today and tomorrow.

But it is not the hot sunshine of the day that people need to be wary of, but roasting night-time temperatures of at least 20C (68F) in some parts which pose the most threat.

Head of health forecasting at the Met Office Wayne Elliott said: "While there is the possibility of daytime temperatures reaching trigger thresholds, it is the night time values which are of real concern.

Pathetic former rulers of the world!

Tales of Christian intrigue

Rowan Williams under siege over gay bishop veto | UK news | The Guardian

The intricate ties between State and Church in England leads to all sorts of strange political intrigue, such as in this story.

First, within the Church itself, there's a name leaking spy, and Rowan wants to know who it is:

Dr Jeffrey John, the dean of St Albans, was in the running for the senior position at Southwark until his name was leaked, enabling conservative clerics to stop the appointment. An embattled Williams has now launched an inquiry at Lambeth Palace to find out who divulged the name .

The archbishop was appalled that John's name was disclosed in a successful attempt to derail his candidacy, exactly seven years after he was forced to stand down as the prospective bishop of Reading following a previous outcry by conservative evangelicals against John's sexuality. Fingers are being pointed at the same evangelical hardliners who orchestrated the 2003 campaign.

Now the liberals in the Church want the PM to step in:

John's supporters called for David Cameron to demonstrate his gay-friendly credentials by overruling the Crown Nominations Commission and insisting that John's name be considered further. They accused the archbishop of betraying his old friend a second time.

One senior cleric said: "The time of reckoning has come for Rowan. The events of seven years ago have bitten him hard in the very week women bishops comes to the crunch. He should realise there are greater considerations, like truth, justice, openness, fidelity to the rules and all those things the church proclaims. Many are dismayed by his constant capitulation to the fringe noisemakers.

"He could recover some credibility if he went mitre in hand to the PM and asked him to intervene and use his constitutional prerogative to consider the second name, whoever that is, and then to reject both if he so chooses."

The "mitre in hand" bit sounds a bit threatening, if you ask me. Reminds me of "The Bishop."

Now to be even handed (for once), I'll also link to a story of the (not intended to be) rich and famous from the Catholic Church:

To his congregants, he lived the humble existence of a pastor.

But a high-flying Connecticut priest was charged this week with first-degree larceny in the theft of almost $1.3 million from his church's coffers to fund a lavish double life that included swanky hotels and male escorts, said Capt. Chris Corbett of the Waterbury Police Department in Connecticut.

Father Kevin Gray, 64, a former pastor at Sacred Heart Church in Waterbury, allegedly embezzled money from the church over the course of seven years.

He used it to pay for fancy restaurants, clothing, vacations, hotels, a New York City apartment and a male companion's tuition at Harvard University, according to an affidavit obtained by CNN affiliate WTIC and filed with the Connecticut Superior Court.

The affidavit says that between June 2003 and March 2010, Gray spent about $205,000 at high-end restaurants, $132,000 in hotel stays and $85,000 at clothing stores. While in New York City, he frequented the Waldorf Astoria, Omni Berkshire, and the W Hotel Times Square, among other posh hotels, the affidavit states.

I wonder if his male "companions" knew he was a priest at all?

Stupid games

The depravity of Major League Eating. - By William Saletan - Slate Magazine

I've never quite understood how grotesque eating contests have become popular in America. William Saletan looks at the issue, and the weird fact that food companies sponsor these events, and ends this way:

Fifty years from now, when historians are looking for a moment that captures the depravity of our age—the gluttony, the self-destruction, the craving for worthless fame—it won't be bathhouses, Big Love, or AdultFriendFinder. It'll be Joey Chestnut stuffing that 68^th hot dog down his unresisting gullet, live on ESPN. Or, worse, it'll be the guy who broke his record.

He could well be right.

That octopus

I see Spain beat Germany in the World Cup last night, as predicted by Paul the German psychic octopus.  (I didn’t know his name til this morning.)

Just how long has this octopus been getting soccer right?  According to Salon:

Paul, who's been calling the outcomes of German football matches for the last two years, has only failed once, unsuccessfully ripping into the German-designated mussels before the Euro 2008 final went to Spain. His predictions are so revered that they're carried live on German television, giving Europeans something to preempt reruns of "Baywatch."

He has his own Wikipedia page, which gives some more details of the numbers:

Paul is reported to have correctly chosen the winner in five of Germany's six UEFA Euro 2008 matches.[10] He predicted Germany to win every match except a loss to Croatia. He incorrectly predicted Germany over Spain in the final in 2008.[11] He has correctly chosen the winner in each of Germany's six matches in the 2010 FIFA World Cup.[12][13][14][15] He also correctly predicted Spain's victory over Germany in the semi-final of the World Cup 2010 in South Africa.[16]

That is a surprising record.  I am curious how this affects the betting market.  Wouldn’t they have an interest in seeing him gone?  

Travel in Morocco

Airport organisation leaves a lot to be desired in Morocco, apparently.

A short Greene note

I just finished reading Graham Greene’s “The Heart of the Matter”, which, according to the blurb on the back, is “widely considered one of his finest novels.”

I beg to differ.  As with Brighton Rock, there’s a deep psychological improbability about the main character.  Worse still, many of the musings on God and theology are so cryptically expressed, I can’t even understand them.  Evelyn Waugh, as a very Catholic writer, was much easier to understand in this regard.  

It’s interesting to note that I can broadly agree with George Orwell’s review of the book, to which Wikipedia conveniently links.   (I would feel even better about that if I liked 1984, but I am amongst the handful of people in the world who can’t stand it.  And while we’re on Orwell,  why does comedian Will Anderson seem to be taking styling tips from him?)

This is the fourth Greene that I have read.  I liked two, and thought the other two were bad.  I might give one more a go.  The Quiet American, perhaps? 

Housing should be cheap in Russia soon, too

Population Decline in Russia

Inspired by a report that large numbers of (probably drunk) Russians have drowned during this year's heat wave, I did a Google and came up with the above recent report on Russian demographics. The situation there is much worse than I expected:

Russia has a very high death rate of 15 deaths per 1000 people per year. This is far higher than the world's average death rate of just under 9. The death rate in the U.S. is 8 per 1000 and for the United Kingdom it's 10 per 1000. Alcohol-related deaths in Russia are very high and alcohol-related emergencies represent the bulk of emergency room visits in the country.

With this high death rate, Russian life expectancy is low - the World Health Organization estimates the life expectancy of Russian men at 59 years while women's life expectancy is considerably better at 72 years. This difference is primarily a result of high rates of alcoholism among males.

Wow.

As for the low birth rate, they have a pretty "big government" way of tackling that problem:

Health Minister Tatyana Golikova said 14-year-olds will undergo more intense medical checks at school starting next year, which could help reveal possible reproduction problems and start treatment on time.

"More intense medical examinations of teenagers are planned to start from 2011 with the goal of examining their reproductive function and recommending individual medical courses, which would identify and treat reproduction problems," Golikova said.

....she said illnesses among schoolchildren rose 9.3% in the past decade, with more than 20% of schoolchildren having chronic illnesses and over 50% of teenagers having health problems that could affect their reproduction ability in the future.

Golikova also highlighted growing alcohol consumption and smoking habits among children.

Sounds like a depressing place.

Tuesday miscellany

There have been quite a few stories around lately worth noting, even if I don’t have time to do full posts on them:

*  A scientist cautioned against burying CO2, again. 

*  Ziggy takes the Gulf oil disaster as an opportunity to favourably compare nuclear to fossil fuels.   Some good figures included in there.

*  Last night’s Four Corners, the first of a two part show on the Australian soldiers in Afghanistan, was great viewing, and the soldiers and officers interviewed presented as  intelligent, compassionate and competent.    The country itself presented as pretty much the opposite and, frankly, hard to care about, but the problem is it can be good at exporting trouble.

*   A Melbourne woman discovers that not drinking 8 cups of coffee of day changes her personality for the better.  She should be shaking less, anyway.

*  Julia Gillard makes her first major policy mistake.  She decides to be a Twitter. 

*  Slate examined the novel idea that our favourite mind altering parasite, toxoplasma gondii, may help soccer performance.   Don’t tell your kid’s coach, especially if he has access to kitty litter.

Revisiting ocean acidification

I’m pretty busy this week, but if I can get readers to look at one article, it would be the very balanced one that appeared in The Economist on ocean acidification.

The article’s subtitle is “ocean acidification threatens the world’s oceans, but quantifying the risks is hard”, which is probably a fair statement given the current state of play in the research.  

It has always been suggested that there will likely to be winners and losers in the ocean from acidification, and this year some researchers have proposed that a meta-analysis of studies to date indicate that sea life may be more resilient than originally thought.  This has been immediately attacked by other researchers pointing out the complexity of the problem:  you have to look at how lower pH affects organisms at all stages of life, as well as warming ocean temperatures, and nutrient levels too.

There are still studies just coming out which have tried to work out more details as to different species’ responses.   Here are a few:

*  it’s still not looking great for the pteropods, one of the major fish foods of the cold oceans, although this study got some results a bit different from previous ones, and much uncertainty seems to remain.  (In fact, my general impression from reading  about this topic for a number of years now is that there is still a surprising lack of detailed knowledge about the detailed bio-chemistry of  sea creatures that build shells, in particular.) 

*  for the blue mussel, the effects on the larval stage are not good.

* on the other hand, for one species of clam, lower pH seemed to do no harm at all.

The problem with some of these studies must surely be how hard it is to accurately replicate the ocean environment in the lab for certain creatures, particularly if they don’t just float at one depth all day, as is the case (I seem to recall) with pteropods.

There has also been renewed comment about how widely the pH of ocean areas (particularly near the coast, I think) changes naturally in a short space of time.  The suggestion is that if creatures can survive that already, they are possibly resilient to forecast lowering of pH.  Yet, surely a significant drop of the  average pH a creature experiences during the day could be very important, even if the same creature spends part of its day/week at such a lower pH already.

Anyhow, as I said, The Economist article does a good job at explaining the current uncertainties, and suggests that it may well be coral reef studies that come up with the definitive proof that acidification will have major effects.  Here are the concluding paragraphs:

If reshaping food webs marginalises the pteropods, the salmon will have to adapt or die. But though the mesocosms may shed light on the fate of the pteropods, the outlook for the salmon will remain conjectural. Though EPOCA is ambitious, and expensive, the mesocosms are too small to contain fish, and the experiments far too short to show what sort of adaptation might be possible over many years, and what its costs might be.

This is one of the reasons why the fate of coral reefs may be more easily assessed than open-water ecosystems. The thing that provides structure in open-water ecosystems is the food-web, which is hard to observe and malleable. In reefs, the structure is big lumps of calcium carbonate on which things grow and around which they graze and hunt. Studies of Australia’s Great Barrier Reef show that levels of calcification are down, though it is not yet possible to say changes in chemistry are a reason for this. Current research comparing chemical data taken in the 1960s and 1970s with the situation today may clarify things.

But singling out the role of acidification will be hard. Ocean ecosystems are beset by changes in nutrient levels due to run off near the coasts and by overfishing, which plays havoc with food webs nearly everywhere. And the effects of global warming need to be included, too. Surface waters are expected to form more stable layers as the oceans warm, which will affect the availability of nutrients and, it is increasingly feared, of oxygen. Some, including Dr Riebesell, suspect that these physical and chemical effects of warming may prove a greater driver of productivity change in the ocean than altered pH. Wherever you look, there is always another other problem.

No reason for complacency, I say.

An anti-Rudd cornucopia

I am happy to admit that I was completely unmoved by Rudd’s farewell press conference, which many people have called “emotional” and “hard to watch”.  As I had long decided that there was a high level of artificiality in his public persona, it was simply a curiosity to me that he does seem to have a nice supporting family, which I can only assume he treats very differently to how he reportedly treats co-workers and underlings. 

And to justify my feelings about Rudd, it’s good to read the stories that many people now feel freer to talk about since his departure.     The Australian has put together a long article full of  anti-Rudd anecdotes.  Good reading.

Steganography appears before our eyes

There’s an interesting report here in the Christian Science Monitor about those (alleged) Russian spies arrested in America using steganography:

The alleged Russian spies recently arrested by the FBI are accused of encoding messages into otherwise innocuous pictures, marking the first confirmed use of this high-tech form of data concealment in real life, experts say.

The accused spies posted the seemingly mundane photos on publicly accessible websites, but then extracted coded messages from the computer data of the pictures, according to the criminal complaint filed by the FBI. Although computer scientists have theorized about the existence of this communication technique for over a decade, this is the first publicly acknowledged use of the technique.

A good explanation of the technique follows:

To generate the picture on a computer screen, the computer assigns every pixel three numeric values that correspond to the amount of red, green or blue in the color the pixel displays. By changing those values ever so slightly, the spies could hide the 1’s and 0’s of computer language in the picture’s pixel numbers, but without altering the picture’s appearance to the human eye, Bellovin said.

When this was first widely discussed a decade or so ago, it did strike me as a particularly clever idea, and the growth in online photo sharing sites since then must make the number of places coded photos could be sitting there waiting to be read by the right person ridiculously large.

What’s more, it’s not as if the software to do it is particularly hard to find.  If you search Sourceforge, quite a few different open source programs for it are available.

It’s all so James Bond, I only wish I had a dire secret and someone to share it with.

Most unusual

Found via Tigerhawk, here’s something I don’t recall ever seeing before in a political ad:  good natured humour.  What an innovation!

Why does this man get paid to direct?

“This man” being M. Night Shyamalan, a one hit wonder whose career success rate can’t take any steeper trend downwards; it’s been in freefall for a few years already.

Latest evidence:  “The Last Airbender”, with Roger Ebert opening his review with:

"The Last Airbender" is an agonizing experience in every category I can think of and others still waiting to be invented. The laws of chance suggest that something should have gone right. Not here.

and ends with:

I close with the hope that the title proves prophetic.

Amusing.  In the WSJ review, we get this bit about the lead actor:

According to Mr. Ringer's understandably slim curriculum vitae, he holds a first-degree black belt in taekwondo. To judge from an informal interview posted on YouTube, he is extremely personable, lively and humorous when he's off screen. On screen, alas, he is none of those things, thanks to the reverse wizardry of his director. (No one else can be blamed when an actor has had no professional experience.)

The review then ends with the exactly the same key question I started with (I only realised this after I started the post):

All of which brings us back to the question of expectations, and how Mr. Shyamalan keeps getting work. Eleven years ago he electrified the movie world with the emotional power and dramatic surprise of "The Sixth Sense." He followed up with two flawed but intriguing features, "Unbreakable" and "Signs." In the past eight years, though, his oeuvre has gone from bad ("The Village") to worse ("Lady in the Water") to worst ("The Happening.") Purists might argue that his last film was less dreadful than his penultimate one, but the hallmarks were the same: stilted language, robotized acting, glacial pace, ponderous style, dramatic ineptitude and negligible energy. I never meant to make this review an exercise in career assassination, but I can't help thinking of all the lavishly talented filmmakers who have earned and never gotten a shot at big-budget success. What's the secret of this guy's failure?

Not great news

Per-Capita Emissions Rising in China

Carbon dioxide emissions per person in China reached the same level as those in France last year, the Netherlands Environmental Assessment Agency said Thursday.

The Dutch agency said that per capita emissions were 6.1 tons in China in 2009, up from only 2.2 tons in 1990. Among the French, emissions were 6 tons per person last year, said Jos Olivier, a senior scientist at the Dutch agency.

Per capita emissions in France tend to be lower than in some other industrialized countries because of the country’s heavy reliance on nuclear plants to generate electricity rather than fossil fuels. Per capita emissions in 15 nations of the European Union were 7.9 tons in 2009, down from 9.1 tons in 1990, the study said. In the United States, the figure was 17.2 tons in 2009, down from 19.5 tons in 1990.

Over all the Dutch agency found that global emissions of carbon dioxide, the leading greenhouse gas, were unchanged last year. That came as a surprise: Because of the onset of the worst economic crisis in decades, other bodies like the International Energy Agency had predicted a significant decline in 2009, the report said.

But the hefty increase in emissions from fast-developing parts of the world like China and India had the effect of canceling out the sharp decline in emissions elsewhere. Emissions from China and India “completely nullified CO2 emission reductions in the industrialized world,” the report said.

Bye bye Mel

I never cared for his work anyway, but I think we can safely say that if these recordings are true, Mel Gibson will never likely “do lunch” in Hollywood again.  At least, not with anyone who matters.

Nice blog

Well, that's handy. I've added to the blogroll James' Empty Blog, which has the pretty unique feature of covering my interests in both climate change and life in Japan. (James Anann is a climate scientist living there, and lovely photos of the country - usually taken by his wife I think - are a frequent feature.)

There is also an interesting post on marriage in Japan, and how the ceremony has no legal significance at all.

One for me, please

This is a product that does address an actual problem which has bothered me many times: fitting all those different plugs and transformers in the one power board. I hope it is coming to Australia:

Holy digital fraud!

I have to admit to a certain admiration for the chutzpah of the mix of the religious and the scientific in this fraud from Korea:

A South Korean medical professor who invented a digital device he claimed could transform tap water into holy water is facing fraud charges, Seoul police say.

Authorities say the professor claimed to have digitally captured the supposed curative powers of holy water on devices he sold to more than 5,000 people for a total profit of nearly 1.7 billion won ($1.7 million)….

Police say the 53-year-old professor claimed he obtained holy water from the shrine to the Virgin Mary at Lourdes - a world-famous Catholic pilgrimage site in France - and preserved its supposed healing powers in digital form.

He claimed to be able to digitally transfer those powers onto ceramic and paper filters and plastic cards used in water purifiers.

He and his associates allegedly told customers that different devices cured different illnesses including diabetes and tumours.

The professor sold the ceramic filters, which cost 1,500 won ($1.50) in stores, for 40,000 won ($39).

 

Movie "meh"

I came home the other night to find my son watching Avatar on DVD. I watched 10 minutes or so of alien action, and came away not so impressed with their realism. They felt only marginally better than the completely computer created aliens of the last Star Wars trilogy, I thought. Yes, the faces had overcome some of the "uncanny valley" that fully digital humans still have, but the motion of entire bodies looked completely convincing only sometimes. I assume some of the figures were created by digitising film of actors running, jumping etc, and some not.

The sense of gravity acting completely realistically on digitally created bodies always seems to me to be the weakest point in these movies. They just don't seem to fall or jump in quite the right way.

And anyway, as I have written before, I am pretty much over any movie where the digitally created nature of certain scenes with hundreds or thousands of figures is inherently obvious.

So, maybe I'll devote more time to watching Avatar before I give it a verdict, but my initial reaction is a big "meh".

Nurse!

Greg Sheridan thinks this:

JULIA should have made Kevin foreign minister already.

Well, I hope some of the Tony Abbott mental health money has been earmarked for journalists who have completely lost touch with reality.

Paris by Griff, and memories best forgotten

Griff Rhys Jones' series "The Greatest Cities in the World" has done New York and London, and I thought they were a little dull. The material was a touch too familiar, and Griff mugs a touch too much for the camera.

But the third one on Paris was very enjoyable. You can still catch it on ABC iView.

There was one long section in which he goes exploring under the city in the catacombs created by quarrying, and it made me realise I must still be capable of claustrophobia.

I once had a moderate attack of it while on a tour of some caves near Canberra. One section involved a narrow corkscrew type staircase, where the head height was pretty low, and it was while in this tight corner that the line of people ahead of me stopped, presumably while some goose ahead was admiring a particularly nice stalactite or something. There were people backed up behind me too, and it was this feeling of being stuck and being unable to move forward or backward in a space so confined that I couldn't even stand straight that suddenly made me feel panicky. I don't think I said anything, or maybe I did ask the people ahead of me if they could keep moving, but my heartbeat definitely rose and it felt a like a sinking feeling in the stomach. The line did start to move again soon enough, and I was able to complete the tour, as the cave opened up again a short time later. But I really wanted to get out as quickly as I could without making a scene.

This all came as a bit of a surprise to me, and for a couple of years later I was a little worried that it might come again in some other context. Would a aircraft make me feel like I have to rush to the door to open it at 30,000 feet? I did get a little worried on a couple of flights, but maybe it was worry about what would happen if I did get the claustrophobic feeling, rather than claustrophobia itself. Fortunately, that passed pretty soon, and long haul flights have not worried me since.

It made me feel a bit disappointed that maybe I was never cut out to be an astronaut after all, as per my childhood daydreams. (All capsules prior to the shuttle were an incredibly tight squeeze, and claustrophobia is something for which the astronauts are still definitely tested *.)

Anyhow, years later I did visit the Jenolan Caves, which I had been to as a boy with no trouble. I took a couple of tours and was OK; as long as there is plenty of headroom, I can get through it.

But last night, watching Griff wriggle down a hole that was the link between two underground tunnels gave me an instant reminder of the sensation of claustrophobia. It's been a while since I have felt that, but I think some other shows about cave explorers have reignited the feeling too.

For the same reason, I don't like to imaginatively put myself in the position of those Beaconsfield miners who survived the mine collapse in such a small space. Not that you would ever find me seeking work as a miner underground, but re-visiting in your mind a claustrophobic feeling is almost certainly not a good way to hope to avoid the feeling in the real world again..

For those who have worse attacks of it than me, it must feel very bad indeed.

* One site talking about being an astronaut as a career writes:

Astronauts-in-training participate in scenarios that simulate weightlessness, heavy gravity (excessive G-forces) and navigate nature's call in an unbroachable interstellar suit. Intensive psychological screening, required of all applicants, is supposed to weed out those with claustrophobia, but one or two are discovered annually in the program and dismissed.

Another article, talking about civilians who may be taking flights into space, writes this:

Jeff Feige, CEO of Orbital Outfitters, a commercial spacesuit developer, said that the training they envision for the use of their suits will range from basic classroom familiarization to simulated pressurization of suit and emergency egress from the vehicle while wearing the suit. Something as simple as testing putting on the suit can be useful for identifying people who have claustrophobia, he said. “A lot of people don’t realize they’re claustrophobic until that helmet is locked and they’re told they can’t take if off. And then all of a sudden they realize they are feeling a little uncomfortable and this isn’t exactly what they had expected.”

Aggressive agnosticism

The rise of the new agnostics. - By Ron Rosenbaum - Slate Magazine

I really like this article in which Rosenbaum argues that the New Atheism is too much like the old Theism, and that it's time that agnosticism re-asserted itself as the true home of intellectual honesty.

All quite correct, in my opinion.

Don't tell the Japanese

Humpback survey indicates growing population

A recent humpback whale count indicates a recovery in the population of animals migrating along the mid-north coast of New South Wales.

In five hours last Saturday, 109 humpbacks were spotted off Tacking Point near Port Macquarie.

Sue Phillips from the local National Parks office says that is a 10 per cent increase on last year....

"Recent DNA testing has shown that after the whaling years it seems as if the humpback whale population in eastern Australia got down to around about 115 individuals," she said.

"Now we think it's back up over the 10,000 mark."

First the good news…

All very large asteroids at risk of hitting Earth should be identified fairly soon:

"In a few more years, we'll be able to say that there's nothing out there to cause a global catastrophe,” said David Morrison, director of the NASA Lunar Science Institute and senior scientist for Astrobiology at NASA's Ames Research Center.

Then the bad news:

“But, there'll be a million that will be big enough to wipe out an entire city. It'll take a long time, if ever, to find them and figure out their orbits. The bottom line is, we could be hit by one of those small ones at any time, with no warning at all. Right now, I can say almost nothing about the probability of one of those small objects hitting us, because we simply haven't found all of them."

The article also notes that some scientists still think a nuclear bomb would be the best way of dealing with a large, threatening, asteroid.

Sensitive region

A new temperature estimate going back a few million years comes up with this conclusion:

"Our findings indicate that CO₂ levels of approximately 400 parts per million are sufficient to produce mean annual temperatures in the High Arctic of approximately 0 degrees Celsius (32 degrees F)," Ballantyne said. "As temperatures approach 0 degrees Celsius, it becomes exceedingly difficult to maintain permanent sea and glacial ice in the Arctic. Thus current levels of CO₂ in the atmosphere of approximately 390 parts per million may be approaching a tipping point for irreversible ice-free conditions in the Arctic."

But they taste good

Someone has written a book about how introducing rainbow trout to its non-native rivers around the world has (allegedly) been an ecological disaster. 

I am not entirely convinced; they taste good, look nice, and don’t muddy the water.

Don’t do it Julia

Julia Gillard is undecided as to whether she will have a Twitter account.  Please don’t.

Rounding up the porn

This is just about the silliest thing I have heard a Christian lobby argue:

The pornography industry and the Christian conservative lobby have united in opposition to a proposal to create a new domain name catering specifically for pornography on the internet….

Australian Christian Lobby spokesman Lyle Shelton says the group opposes the new domain because it sees it as further legitimising the pornography industry.

"Anything which further mainstreams and legitimises the porn trade is obviously not a healthy thing for children," he said.

"It is not a healthy thing for the wider society because it just continues to take us down this path where profiting off naked young women continues to gather acceptance in our society and of course we are seeing the pornification of culture seeping into our everyday lives."

Further legitimising the porn industry! I would have thought having porn sites spread across all possible domains gives it an ease of access which should be much more of a concern for them than any alleged “legitimacy” rounding it up into one domain would create. In fact, the porn industry agrees with this lobby but for entirely the opposite reason: it doesn’t what an internet porn “ghetto” created, because people might be able to avoid it easier.

The porn industry also fears that conservative politicians, especially in the US, will seek to force all current porn into the new domain.

Well, I fail to see what the problem with that would be, apart from porn producers facing loss of revenue because it would make voluntarily filtering access to it much, much easier. In fact, now that I think of it, surely a lot of their revenue comes from people paying for access to the “quality” material, and how much of that goes on at work or in any place other than a guy’s house, late at night? In other words, maybe the feared loss of revenue is greatly exaggerated. And besides which, is there some reason I should be concerned that this industry might lose money?

I don’t see it should at all be a significant concern that different governments could have different standards for what they would want in .xxx. Surely it would be a major improvement even if only explicit sex was required to go there. I don’t see street protests going on about why XXX Adult bookshop material is not allowed into the front of the local newsagent. If a country tries to force too much into .xxx, its a matter for renewed debate about censorship and classification, and this is often a topic of some debate for movies and other material, for example. That it may become a debate in relation to internet content, big deal.

It’s not about preventing access to porn to any adult who wants it; its about making it much easier to prevent access to it in places it undoubted should not be, such as workplaces and the kid’s bedroom.

As for loss of value in existing .com porn address, whereby people could argue that they have lost an asset overnight, couldn’t that be partially addressed by having the .com name become a simple referral page to the new .xxx address for the same enterprise? Those who want to get to formerly .com material can still find it, just by one more click.

Unless there is some vital technical aspect to this I am missing, round it up, I say.

Clean energy blues

A few items of interest about clean energy:

* Technology Review has a pretty balanced report on the German experiment in boosting solar power generation by generous "feed in" tariffs for your domestic solar cells. On the one hand:

The German grid now gets more than 16 percent of its electricity from these sources, and the government has raised its target for 2020 from 20 percent to 30 percent. The country avoided pumping about 74 million metric tons of carbon dioxide into the atmosphere in 2009. The German environment ministry also touts a side benefit: nearly 300,000 new jobs in clean power.

But on the other hand, some say:

..the German policy is a government boondoggle. "It's not surprising that if you throw enough money at a certain technology, people will use it," says Severin Borenstein, codirector of the Energy Institute at UC Berkeley's Haas School of Business. Yes, the incentives triggered a frenzy of renewable-power installations, but at "very high prices," says Henry Lee, director of the Environment and Natural Resources Program at Harvard's John F. Kennedy School of Government. The spending on photovoltaics has been especially cost-inefficient in terms of producing power, Lee adds, because "Germany is the cloudiest country in Europe." Despite the weather, Germany now accounts for half the world's 20 gigawatts of installed solar capacity. "What that gets you," says Lee, "is high prices for electricity, locked in for 20 years, from technology that will be out of date within three years." Concludes ­Borenstein: "That's a failure of public policy."

I do find it particularly odd that cloudy old (northern) Europe is the part of the world really going for solar. I remain sceptical of the wisdom of the program, although I presume it would all make more sense in places like the top half of Australia.

* Technology Review also has a long article about Zhengrong Shi, the Chinese businessman (but Australian citizen) and his hopes for improved solar cell efficiency in the not so distant future. Still no real talk in the article about how you store the electricity once the sun goes down, though.

* The 7.30 Report featured a story about an Australian company which is going off to Europe to build its ceramic fuel cells. These seem very promising, yet are getting little support from the Australian government because they run on natural gas. This seems pretty silly to me, especially if these claims are true:

Ceramic Fuel Cells claims its Blue Gen unit is much more efficient than the current power grid where up to 80 per cent of the energy can be lost in transmission and it says the unit produces two thirds less carbon dioxide emissions than coal fired generators.

Interestingly, the Greens think fuel cells should get feed in tariffs, and Senator Nick Xenophon points out that if the government is going to not pay feed in tariff for energy from natural gas, why do they pay renewable energy money on heat pump hot water systems, which run on electricity from coal? Fair point, and it certainly seems true that no single party has all the answers to sensible clean energy policy in Australia.

I first mentioned this Australian company here 2 years ago. Seems that they are moving slowing towards large scale production.

A surprise from the bottle

This is quite a surprising finding, I reckon:

Mothers who drink alcohol while they are pregnant may be damaging the fertility of their future sons, according to new research to be presented at the 26th annual meeting of the European Society of Human Reproduction and Embryology in Rome today (Tuesday 29 June). Doctors in Denmark found that if mothers had drunk 4.5 or more drinks a week while pregnant, then the sperm concentration of their sons, measured about 20 years later, was a third lower in comparison to men who were not exposed to alcohol while in the womb.

The researcher is happy to be cautious about this study, though:

However, because this is an observational study we cannot say for certain that the alcohol causes the lower sperm concentrations. It is possible that drinking alcohol during pregnancy has a harmful effect on the foetal semen-producing tissue in the testes – and thereby on semen quality in later life – but our study is the first of its kind, and more research within this area is needed before any causal link can be established or safe drinking limits proposed.

But, if it turns out to be true, it might be the (or at least part of the) answer to the question of why semen quality seems to have been on the decline globally in recent years:

"If further research shows that maternal alcohol consumption is a cause of reduced semen concentration in male offspring, then we are a bit closer to an explanation of why semen quality may have decreased during the last decades and why it differs between populations. If exposure to alcohol in foetal life causes poor semen quality in adult life, we would expect that populations with many pregnant women drinking, possibly heavily, in pregnancy would have lower fertility in comparison with populations of where pregnant women do not drink."

Purple health

BBC News - Nitrate content 'behind benefits of beetroot juice'

A study in the US journal Hypertension found that blood pressure was reduced within 24 hours in people who drank beetroot juice or took nitrate tablets.

The higher the blood pressure, the greater the impact of the nitrates.

This research suggests there is hope of using a more "natural" approach to bring down blood pressure. Nitrates are found in a number of vegetables.

A previous study found that drinking a pint of beetroot juice lowered blood pressure significantly in people with normal blood pressure.

I'm not entirely sure I would enjoy drinking a pint of beetroot juice, but this must be good news for any farmer that particularly enjoys growing this vegetable.

Good old Bettina

Bettina Arndt (who, incidentally, has been married twice herself) comes out with a rather conservative take on the question of the role model effect of Julia Gillard being in a de facto relationship.   I agree with all of it.  Some extracts:

It's fine for Gillard - a 48-year-old woman - to live with her bloke. Yet as a popular role model for women, her lifestyle choice may influence other women into making big mistakes about their lives.

Cohabitation produces two groups of losers among women and children. Most women want to have children - Gillard is an exception - and some miss out after wasting their primary reproductive years in a succession of live-in relationships which look hopeful but go nowhere, leaving them childless and partnerless as they hit 40….

While the de facto lifestyle leads some women to miss out on having children, others are taking the risk of becoming parents despite these unstable relationships. A growing proportion of children is now born to de facto couples - up from less than 3 per cent in 1975 to 12 per cent in 2000, according to data from the Household Income and Labour Dynamics Survey.

It is often assumed these children will provide the glue to keep de facto relationships together, but sadly this is not so. David de Vaus, a sociology professor from La Trobe University, found cohabiting couples who have children are more like to break up than married parents, increasing their risk of the negative impacts of family breakdown.

She then makes this good point:

 Politicians today rarely question social trends, even when all the evidence is they are having negative social consequences. John Howard was the rare exception, when he went into bat for a child's rights to a father in the debate over single mothers and IVF.

Yes, I used to like that about John Howard. We all knew Paul Keating was personally conservative on the matter of gay marriage, for example, but he was politically constrained from saying it out loud. No such problem for John Howard.

As for Julia:  I think it is fair to say that very few people would take her relationship status as a reason for not voting for her.  However, it should be no shock, and a matter of social benefit, if she did marry her partner now or soon after winning an election.  I mean, she would be simply following a pattern that many others have, and I don’t see that it should be seen as a betrayal of feminist principles.    The fact that it would annoy some feminists is just an added benefit as far as I am concerned.

Richo agrees with me

Graham Richardson writes scathingly of K Rudd, the former PM now ordered to take a rest by Dr Julia*:

YOU didn't need a poll to know this tax was going down like a shower of the proverbial. Everybody from Julia Gillard down told Kevin Rudd the resource super profits tax was killing him and the government. But he wouldn't listen. He never listened. This genius actually believed he was the font of all wisdom.

No one moved against Rudd merely because he treated colleagues with total disdain. But it ensured that when the challenge came, success could be achieved at record pace. The margin, had a ballot occurred, would have been embarrassingly large. Faction leaders didn't make caucus members hate Rudd; no, that was all Kevin's own work.

Hate, by the way, was the right description. From lowly backbenchers to cabinet ministers, I have never come across such loathing towards a leader before, let alone a leader who achieved the biggest swing to Labor since World War II at the 2007 election.

*  I wish someone would tell him to take a break from twittering, too.  All normal people over 50 should have the appropriately disdainful attitude to that silly use of the internet, but I’ll take it as a sign of vanity that Kevin doesn’t stop.

Still witty after all these years

Steve Martin can still be amusing, as evidenced by this video from earlier this year:

Kant and rats

Hmm.  Kant keeps making an appearance in stuff I read lately.  Here he is again, in the context of new science about how rat brains get spatial cognition.  Cool.

Bunyip tales

A somewhat interesting article appeared in The Age recently about the Australian aborigines mythological bunyip.   I don’t recall reading this specific theory before:

Australian Museum naturalist George Bennett was first to suggest formally (in 1871) that the bunyip might be an indigenous cultural memory of extinct Australian megafauna, passed down through oral tradition. By 1991, the authors of Vertebrate Palaeontology of Australasia were postulating that, "When confronted with the remains of some of the now extinct Australian marsupials, Aborigines would often identify them as the bunyip."

And in 1998, geologist Greg McNamara told Australian Geo-graphic magazine his theory that the remembered bunyip was actually a prehistoric turtle, Meiolania prisca, "a most impressive beast" up to two metres long with a metre-long, bony club tail and curved 25-centimetre horns.

More Crowe stories

Maybe it's a bit unfair to keep repeating stories of stupid or strange things Russell Crowe has said or done, but it is fun. Today from The Age, it's Russell the film critic:

Howden reveals that Crowe had been originally ‘‘earmarked’’ to play the title role in Shakespeare in Love (1998), but then had problems with the script and decided not to be involved. Which is any actor’s prerogative, of course. But then Crowe continues: ‘‘I was f---ing right about that movie too. It was a 100 per cent f---ing home run, except the central character of William Shakespeare was not a f---ing writer ... He was some prissy pretty boy. What the f---? That’s so disrespectful.’’

LOL, as they say.

Space weather and you

Quite a surprise here as to how the sun may affect electronics to a much greater degree than previously realised:

Relatively minor space storms now appear to be behind a range of mysterious mishaps - railway signals malfunctioning in Archangel province in north-western Russia, for example, between 2000 and 2005. A study led by Eugenia Eroshenko of the Pushkov Institute of Terrestrial Magnetism, Ionosphere and Radio Wave Propagation in Troitsk, Russia, examined episodes when signals turned red for minutes or even hours though the track ahead was clear, then spontaneously reverted to green.

Eroshenko's team found that 16 malfunctions of this sort observed between 2000 and 2005 coincided with space storms (Advances in Space Research, DOI: 10.1016/j.asr.2010.05.017). "We were surprised by such a clear correlation," Eroshenko says…

As for transformers:

Intense power surges due to big space storms can heat transformers enough within minutes to damage the insulation needed to prevent short circuits, which can cause them to explode.

More recently, there are signs that transformers can be destroyed by smaller currents over a period of hours or more. A long-lasting 2003 space storm delivered only relatively low-intensity currents to the South African power grid, but damaged several transformers anyway, notes US-based storm analysis consultant John Kappenman.

What next? Tin foil hats work too?

The results are preliminary, but appear in the Journal of Neurology, Neurosurgery and Psychiatry (sounds legit):

Applying magnets to the brains of Alzheimer's disease sufferers helps them understand what is said to them. The finding by Italian scientsts, who conducted a randomised controlled trial of the treatment, suggests that magnets may alter "cortical activity" in the brain, readjusting unhealthy patterns caused by disease or damage. The study was small, involving just 10 patients, and the results are preliminary.

Surprising, but it's not as if it was just a matter of putting magnets in a headband:

For the latest study, Maria Costelli and colleagues applied repetitive TMS – a rapid succession of magnetic pulses – to the prefrontal lobes of the Alzheimer's patients for 25 minutes at a time. Half the patients received daily doses five days a week for four weeks and half received a dummy treatment for two weeks followed by two weeks of TMS. Tests showed that those who had the full course of TMS had significantly higher scores on comprehension of what was said to them – up from 66 per cent to 77 per cent. The improvement was still evident eight weeks after treatment. The authors say the technique did not affect other language abilities or other cognitive functions, including memory, which suggests that it is "specific to the language domain of the brain when applied to the prefrontal lobes".

Half my wish fulfilled

Recently, I indicated that my depression over what looked like the coming appalling electoral choice between Kevin Rudd and Tony Abbott would be resolved if Labor installed Gillard as Leader, and the Liberals went back toTurnbull.

Well, looks like half of my wish has come true.

Basically, Rudd suddenly imploded because he is a two-faced, control freak, vain, celebrity-seeking, boss-from-hell, media tart of a politician who was only installed as leader as a result of his smiley Sunrise appearances which gave Labor the feeling that he was just the right person to not scare the voters from blasting Howard out of the chair which he had unwisely decided to keep for one election too many. There always existed plenty of evidence for all of this; it is amazing that it took the public as long as it did to turn on him (and even now, that it has not turned as completely as it could,) but it is not really that surprising that Labor turned on him at the first possible opportunity.

Now, how am I to hope for Abbott to lose his position? The only way I see is for him to (literally) be caught with his pants down somewhere with someone other than his wife.* It's possible; I should never give up hope!

* Now that I think about it, I speculated once or twice on this blog during Rudd's puzzling rise to power that this was how he might come to grief too, but it was only with his ETS backflip that we all realised he had no testicles anyway. Maybe I'm just longing for another scandal as good as the Gareth Evans/ Cheryl Kernot one.

Odd headline of the day

French cannibal ate cellmate's lung in 'cry for help'

Bad Republican!

How Time and Life magazines helped turn America on to LSD. - By Jack Shafer - Slate Magazine

Well, that's interesting! I didn't know that the Time and Life magazine co-founder and his wife (Henry and Clare Luce) were right into LSD, and this explains why those conservative magazines gave oddly sympathetic coverage of the drug in the late 50's and into the 1960's.

One pleasing strange aspect of this:

Clare's acid trips, which she recorded in her papers now at the Library of Congress, were of the garden variety. She sorts mosaic glass by her swimming pool. She entertains herself looking through a kaleidoscope. During a March 11, 1959, trip, Richard Nixon telephoned Clare at her Phoenix home. An active Republican who served in Congress and as an ambassador, Clare declined to speak to Nixon. How history might have changed if she had shared a little acid with him!

It could have been a stranger conversation than the one Nixon had with Elvis.

It’s ours, all ours

In what would probably be a rare bit of good news for Australian professional astronomers:

MORE than 35 years after Prince Charles opened Australia's biggest optical telescope - a joint venture between our two nations to explore the southern skies - we are bidding goodbye to the Brits.

From next month, the Anglo-Australian Observatory near the NSW town of Coonabarabran will become the Australian Astronomical Observatory.

Its director, Matthew Colless, said the decades of collaboration with Britain had led to many big discoveries about the universe, including a measurement of the matter it contains.

But 100 per cent ownership of the observatory's four-metre telescope, which is still ranked highly in the world, would open up new opportunities for research in the coming decade.

I’ve been there once in the late 1980’s, and I recall it as having a pretty good visitor centre. Somewhere in a drawer I probably have a photo, but here’s one from the web.

Cheap real estate in Japan

We all saw on TV last year how you could buy abandoned houses in many parts of the US for a song. Unfortunately, it looked like many had been thoroughly vandalised, and were in neighbourhoods which might take a decade or so to feel safe and inhabited again. A house for a couple of thousand dollars in such a situation is not such a bargain.

But Japan is a different kettle of fish. (That’s a particularly apt expression for that country, come to think of it.)

Population decline has already set in, and about the only places growing are the big cities due to people leaving the rural areas. I had been wondering if bargains in housing were to be had, and this fascinating article claims that there are:

So just how many vacant properties are there in Japan? According to the Internal Affairs and Communications Ministry in 2008, there were an amazing 4.127 million unoccupied housing units, up 451,900 from 2003.

Some of these are old decaying abandoned homes which you wouldn’t want anyway, but it is still a big number, and it’s only likely to get bigger. The article goes on to provide a website which lists properties for sale as a result of tax foreclosures, but unfortunately it is in Japanese only, and is not exactly what you would call a glossy looking real estate site.

There is one major cultural difference about Japan which is odd to Westerners: except for apartments, modern Japanese do not expect houses to last long:

One reason why foreigners are a good fit to solve the vacant housing problem is that they are more willing to live in older properties and to perform their own maintenance. Japanese have been educated over the last 50 years that housing older than 25 years old should be demolished and rebuilt, leading people to really only want to buy new places. I know this firsthand, after a relative bought a countryside property, built a substantial Japanese-style post-and-beam house on the land (and which will last another 50 to 100 years), but being told by the bank several years ago that the house itself is now considered to already have zero value!

Some suggest that the Japanese expectation for the life of a house is affected by the number of earthquakes it might be expected to endure. But I am sure it is more than that. I was recently speaking to a Japanese couple, now Australian residents, who explained how surprised they were to find that renovated older homes (particularly in the Queenslander style) in Brisbane were expensive and highly valued. I think there is an idea that houses carry any bad luck that happened in them into the future.

Lots of websites say that there is no equivalent to our Foreign Investment Review Board restrictions on foreign purchase of real estate in Japan. (They also say that dealing with real estate agents may not be easy, but the article I linked to says there is a move afoot to encourage real estate agents to be helpful to foreign investors.)

All of this certainly suggests that you don’t buy a house in Japan with an expectation of making capital gain. But the idea of having a holiday home in the very pretty countryside of Japan might be a quite viable option for foreigners in the future.

Cheap books, electronic and otherwise

E-reader prices have taken a tumble in America due to the success of the iPad.

Recently I saw at Dymocks the Kobo e-reader for $199, but they have sold out and you have to place them on order.   I thought the screen was a bit small though, but then I thought the same when I saw a Kindle.

Anyhow, I’ll still wait for the next generation of them before buying.  I’m currently getting plenty of cheap reading by going to the Lifeline Bookfest held every 6 months in Brisbane’s convention centre. 

In January, as I have reported here before, I got Clive James’ first volume of autobiography which I had been wanting to read for years.   This time (on the Queens Birthday weekend) I got the second volume.  I am also getting more Graham Greene, including his autobiography, and he is difficult to find anywhere other than second hand book stores.

One thing you do learn from going to the Lifeline book sale is this:  there are a hell of a lot of Bryce Courtney novels sold in Australia.  Unfortunately, he has no appeal to me at all.

For readers outside of Brisbane who may not understand the size of this Lifeline second hand book sale, here’s a photo from the Brisbane Times which gives a good indication:

We like out second hand books in Brisbane.

Lucky planet

Summer solstice: Did a rampaging planet create Earth's seasons? - CSMonitor.com

Of course I knew of the idea that it was a collision that formed the Moon, but I either didn't know (or had forgotten) that it may also have given us the Earth's very convenient axis tilt that gives us the seasons:

Without that tilt, we might've ended up with more seasons than we could deal with over the course of Earth's history, suggests Neil Comins, an astronomer at the University of Maine. He's written substantially on what alternate Earths might be like and how hospitable they would be for the emergence of life.

The collision thought to have generated the tilt also created the moon, which is responsible for stabilizing Earth's spin axis. Without a moon, "the Earth spinning on its axis is an unstable system in which the tilt goes from straight up and down to far closer to the plain of it orbit than the axis is today," he says.

At its most extreme, this could leave Earth orbiting the sun and spinning on its axis like a chicken roasting on a spit with head and tail alternately aimed at the fire, rather than cooking the bird broadside. Earthlings from one pole to the equator would be in darkness during the solstice, while the other half would be in toasty sunlight. The poles would swap lighting conditions at the next solstice.

Moreover, the moon's presence and its effect on the oceans act as a brake on Earth's rotation rate. By some estimates one turn of the Earth on its axis some 4.5 billion years ago would have taken 6.5 hours, versus 24 today. No moon means a far more speedy cosmic rotisserie.

I don't think the importance of the moon in keeping the axis tilt stable was something that I realised before. Very neat.

Impressive

BBC News - Tornado rips roof off sports arena in Montana

Some pretty impressive video here of tornado damage. Two things of note: the amount of rubbish a tornado can keep suspended in the air for a long time, and the cars and trucks that seem to be passing by quite close to it. (I would be speeding away as fast as possible, but these vehicles don't seem to be in that much of a hurry.)

Expensive brides

I commented a while ago that a documentary about a large restaurant in China seemed to show many Chinese women as being intensely materialistic, and a story about real estate in China seems to back this up:

Unlike in the United States, where home buying traditionally takes place after marriage, owning a place in China has recently become a prerequisite for tying the knot. Experts said securing an apartment in this market signals that a man is successful, family-oriented and able to weather challenging financial circumstances. Put succinctly, homeownership has become the ultimate symbol of virility in today's China.

"A man is not a man if he doesn't own a house," said Chen Xiaomin, director of the Women's Studies Center at the Shanghai University of Political Science and Law. "Marriage is becoming more and more materialistic. This is a huge change in Chinese society. No matter how confident a woman is, she will lose face if her boyfriend or husband doesn't have a house."

Dating websites are now awash with women stipulating that hopefuls must come with a residence (and often a set of wheels) in tow.

Medical technology's downside

A Pacemaker Wrecks a Family's Life - NYTimes.com

This is a long but quite interesting story about how the use of pacemakers in the elderly in the US appears to be prolonging lives that do not want to be prolonged. It has apparently proved difficult to get permission to turn the things off.

It appears that only very recently has the American Heart Association issued guidelines that patients or their "legal surrogates" (people with Enduring Power of Attorney in Australia's case) could request the withdrawal of medical treatment, including implanted pacemakers, and that this would not be euthanasia or assisted suicide.

I wonder if there has been any similar uncertainty in Australia, or if this was largely a product of American concern over litigation. Tell us, Geoff.

That's hot

AFP: Kuwaiti MPs call for shorter work hours to save power

From the report:

Last week, the oil-rich OPEC member almost resorted to power cuts after a sharp rise in demand in response to record temperatures that soared to 52 degrees Celsius (125.6 Fahrenheit), the highest in more than 30 years.

Surely a dry heat of 52 degrees is not exactly healthy without airconditioning, so I am curious as to what happens to death rates when the power is cut off during a day like that. (Then again, I suppose people have been living in the desert for a long time. Why on earth did they stay there?)

Interesting terms found on the Web today

1. Cat therapist. (From New York; not California as you might have expected.)

2. Sexually Satisfying Events. It's a medical term used in trials of libido enhancing drugs, apparently. I wonder if there’s a requirement that two people be involved?

Once a certain age is reached, perhaps a more relevant term is needed, such as "Sexually Satisfying Event Equivalent." (I expect most of mine to involve cheese.)

3. The Theory of Exclusively Local Beables. This is from arXiv, which is a bit of an obvious source for novel phrases: every second paper has a title with a term I haven’t heard of before. Anyhow, “beables” is a charming sounding word, and is described as follows:

J.S. Bell introduced the term “beables” (a deliberate contrast to the vaguely-defined “observables” which, he thought, played too prominent a role in orthodox, Copenhagen quantum theory) to name whatever is posited, by a candidate theory, as corresponding directly to something that is physically real (independent of any “observation”).

The paper talks of “pilot wave” theories to explain the quantum world, and is of some interest, especially in its introductory explanation of how such theories to explain the dual particle/wave characteristics of light were considered from the beginning by Einstein, but they lost out to the “tranquilizing philosophy” of Bohr’s Copenhagen interpretation. (The paper goes on to suggest that there is merit still in the pilot wave idea.)

4. Everyone has two puberties. Recently I link to a list of very dubious ideas Kant had about life, yet today while reading a bit of a rambling article in The Guardian about marriage, I found this:

I think Elizabeth Gilbert gets somewhere close to it when she quotes Kant in his assertion that we humans are so emotionally complex that we go through two puberties in life: the first when our bodies are mature enough for sex, and the second when our minds are.

Sounds about right; good on you Immanuel. (But having reputedly died a virgin, I wonder how he assessed his own preparedness for it.) *

* At another blog earlier this year, I imagined a movie involving Kant (who, apart from alleged sexual inexperience, also never travelled more than 100 miles from his home town of Konigsberg) as actually being a secret prototype James Bond character, involved in political intrigue and bedding femme fatales all over Europe and the Americas in the 1770's. (Wikipedia says he had a "silent decade" in his 40's.) I await the grant for the script from the Australian Film Commission: God knows they haven't funded enough films involving improbable historical fantasies based in Prussia.

Big brother death throes

Charlie Brooker writes pretty amusingly on the final series of the British version of Big Brother. (Yes, it is a sure sign of the cultural sickness at the heart of that country that its BB outlived, and seemed to attract more attention, than its Australian counterpart.)

It’s small, but my favourite line in the article is towards the end:

Throughout the first series, broadcast in 1912, the contestants occasionally sang "it's only a game show!" to keep their spirits up.

The Japanese way

This was reported last weekend, apparently, but I missed it:

Britain’s Sunday Times reported in its online edition that Japan had bribed small nations with cash and prostitutes to gain their support for the mass slaughter of whales.

The International Whaling Commission (IWC) commissioner for Tanzania said “call girls” were made available at the hotels for ministers and senior fisheries civil servants during all-expenses paid trips to Japan, the paper reported.

The Sunday Times’ investigation revealed that officials from six countries were willing to consider selling their votes on the IWC. According to the report, the governments of St Kitts and Nevis, the Marshall Islands, Kiribati, Grenada, Republic of Guinea and Ivory Coast negotiated selling their votes in return for aid. One official said that call girls were offered when fisheries ministers and civil servants visited Japan for meetings.

A top fisheries official for Guinea said Japan usually gave his minister a “minimum” of $1,000 a day spending money in cash during IWC and other fisheries meetings, the paper reported.

More floods = climate change?

String of floods raise climate change questions - Capital Weather Gang

I think this is a pretty balanced article about what the media can appropriately say about recent floods in the States and climate change.

Meanwhile, the UK Met Office says that even if CO2 dropped after its rise, rainfall changes caused by AGW would hang around for decades. Seems pretty academic to me: why bother looking at unrealistic theoretical drops in CO2? Anyway, their modelling for what rainfall changes AGW will cause indicates:

High latitude countries such as Canada and Russia would receive more rain and snow, whereas other regions such as the Amazon basin, Australia and parts of sub-Saharan Africa would receive substantially less.

As the oceans have huge capacity to store heat, releasing the heat relating to a temporary quadrupling of the man-made greenhouse effect would take many decades.

The Met Office computer model is known to project more drying of the Amazon than most others.

Last night's Catalyst had an interesting story on Western Australia being unusually dry for the last 30 years. They don't say it's all CO2's fault; changes to the ozone layer get much blame too.

All a bit of a worry.

Bigfoot discovered? Virginia man says he's on verge of Bigfoot discovery - CSMonitor.com

I can't resist a Bigfoot story, but there's nothing much to this one. Still, it's an excuse to refer people to the Messin' with Sasquatch beef jerky ads from America, which have been around for some years, but I only found them recently. Here's the first, which sets the tone for the rest:



I suppose it's not dissimilar to the Betty White ad I featured recently: I find unexpected violence pretty funny. Sorry.

Also - if you want to amuse yourself (or your kids) by making a film with your webcam of a mini animated Sasquatch doing stuff on your desk - click on the very neat application "Living Sasquatch" on the Jack Links Messin' with Sasquatch website.

Congratulations Alexito...

I don't know what the multiplexes expect when they throw me out for trying to add a bit of atmosphere to Sex and the City 2 with my vuvuzela.
