Three pieces of Slate

Three stories from Slate last week:

* Yay! A complaint about Word leads to hundreds of comments, amongst which, if you go down far enough, are ones by the hidden secret devotees (and users) of Wordperfect. This is a secret cabal to which I belong too; although I must say that I have found the latest version of Word to be much better than earlier versions for some things.

Many people in that thread mention the wonders of Reveal Codes - a Wordperfect feature that does often let you work out a formatting issue, and which Word has never implemented.

I am often amazed when I have had young people out of university, and who have never known anything other than Word, still can't solve some formatting mystery problem in the program that I assumed I couldn't fix simply due to lack of familiarity.

Long may Wordperfect live (it's still updated every 2nd year or so, you know.)

* A complaint about tattoos also makes claims close to my heart (and is rather brave. Mentioning strong dislike of this trend is usually met with some very rabid insults about how us clean skins just don't understand.)

But what is most interesting is that part - a link to an article about research on the possible health consequences of some of the stuff in tattoo inks. I mentioned this before here. Doesn't sound so hot.

* American teenage birthrate is down, and it seems due to increased use of contraception.

I put it down to the decline of the influence of Sex and the City too. Maybe the second movie was so bad that it convinced teenagers who saw it that the show never got sex and relationships right.

Digital cinema and what it means

Movie Studios Are Forcing Hollywood to Abandon 35mm Film. But the Consequences of Going Digital Are Vast, and Troubling 

A few months ago when I went to one of the big, refurbished, cinema complexes (which I usually avoid in favour of cheaper venues), it looked to me as if they must have gotten into digital projection.  The bright looking result looked pretty good to me, and I assumed that it must indicate that Australian cinemas were finally following the US trend I had been seen mentioned on the 'net over the last couple of years.

The big attraction for studios is that digital distribution saves an enormous amount of money in printing copies of movies on film and couriering them all over the country.

Yet, I had also read that Spielberg (amongst other directors) does not want to shoot on digital cameras.  His films are still shot on film and then converted to digital format.   But increasing, I think,  films (especially special effects heavy ones) are made with digital cameras too.

Anyway, the changes this all means to the movie making business are all set out in interesting detail in the above article.

One of the most surprising things is that, as with computer file format wars generally, the movie industry doesn't have its act together on this yet:

 And even after the films are converted to digital, Jan-Christopher Horak, director of the UCLA Film & Television Archive, calls the challenges of preserving them "monumental." Digital is lousy for long-term storage.

The main problem is format obsolescence. File formats can go obsolete in a matter of months. On this subject, Horak's every sentence requires an exclamation mark. "In the last 10 years of digitality, we've gone through 20 formats!" he says. "Every 18 months we're getting a new format!"

So every two years, data must be transferred, or "migrated," to a new device. If that doesn't happen, the data may never being accessible again. Technology can advance too far ahead.

Anyhow, I just found the whole article a good read.

Climate change, probabilities, etc

Well, the scientific debate about how to properly think about the effects of climate change continues.

John Nielsen-Gammon makes a point about the extraordinarily warm March in much of the US not being quite as extraordinary as it seems. But in doing so, he seems to play into the hands of skeptics whose inclination has long been to shrug shoulders and say things like "what, so global warming might only add 1 degree to what was already a heatwave? Big deal."

Michael Tobis has a problem with this approach, and has a post with a good analogy, and some important diagrams.

And over at AGW Observer, a whole batch of papers looking at the Russian heat wave of 2010. Even Nielsen-Gammon seems to like this paper in that list, which gives a good explanation of how you can reconcile apparently conflicting statements about climate change and the heatwave.

Update: and as if on cue, a person commenting at John N-G's blog takes exactly the wrong message in the way that I (and others in the thread) thought would happen. It should be obvious which one I mean.

Unhealthy expeditions

Mind Hacks notes an extract from a 2008 Lancet article on mental health issues that arose during polar expeditions. I don't recall hearing about the last one before:

Frequently, the entire crew of a polar expedition would experience melancholy and depression, as was the case of the Belgica expedition to Antarctica in 1898–99. As described by the great polar explorer and expedition physician, Frederick A Cook, “The curtain of blackness which has fallen over the outer world of icy desolation has descended upon the inner world of our souls. Around the tables, in the laboratory, and in the forecastle, men are sitting about sad and dejected, lost in dreams of melancholy from which, now and then, one arouses with an empty attempt at enthusiasm.”

Cook tried to treat these symptoms by having crew members sit in front of large blazing fires. This baking treatment, as he called it, could be the first recorded attempt to use light therapy to treat symptoms of winter depression or seasonal affective disorder. Other expeditions, such as the Greely expedition of 1881–84, met a far worse fate than the Belgica exploration. In their attempt to establish a scientific base on Ellsmere Island in the Arctic, the crew of the Greely expedition was driven to mutiny, madness, suicide, and cannibalism, leaving six survivors of a crew of 25 men.

This interesting looking site "Time to Eat the Dogs" (about science, history and exploration) does say that there were "rumours" of cannibalism on the Greely expedition that circulated in the press at the time. Certainly, one man was executed for stealing shrimp from the communal mess pot. Mind you, they were stuck in the Arctic for 3 years before rescue. No wonder they got stressed.

British humour

Well, that went against expectations.

Over Easter, I took the kids to see the latest Aardman film, Pirates! - Band of Misfits. It got a very high 91% approval rating at Rottentomatoes from British and Australian critics; I liked Wallace and Gromit in their movie and TV outings; what could go wrong?

I thought it was pretty awful. Somehow, the jokes were obvious but just not laugh-out-loud, or even charmingly witty. You virtually had to be an adult to get most of them, but even then, they just came across as a bit, I don't know, trying too hard? Certainly, you could tell from the increasing restlessness of the younger members of the audience that the film was just not hitting that target at all. My kids said afterwards that it was only so-so. At least it gave me an opportunity to talk about Charles Darwin and evolution, but a springboard for some mild education is not why one goes to see an Aardman film.

Then today, my wife had hired Johnny English Reborn on DVD for the night (it's school holidays still). I knew it got so-so reviews (38% on Rottentomatoes) and (I now know) made an embarrassing $8,000,000 at the US cinema. (It made more than that in Australia alone.)

Yet we enjoyed it a lot. It's a well crafted, good looking movie with just the right mix of witty satire of James Bond and outright silliness, all without the excessive crudeness of the Austin Powers movies.

Strange how expectations can be upended.

Drug reform and economics

A week or two ago, the issue of drug law reform was again in the news because some advocacy group no one had heard much of before put out a bit of PR stuff about how a panel had met (largely comprising retired politicians, it seems) and decided the "war on drugs" had failed and there should be reform.

When I actually looked at their glossy press release, I thought it was remarkably lightweight and hardly worth the attention. One prominent person on the panel, Dr Alex Wodak, has been calling for drug easing for decades, although how he expects it to help the already heavy drug using population of inner Sydney that he treats has never been clear to me.

Anyway, I was quite happy to see on the weekend that a sort of backlash against the wooliness of this exercise appeared in both Fairfax and News Limited.

Bruce Guthrie wrote:

I am still wondering how the release of their wafer-thin report got the whole country talking about surrendering to illicit drugs. I'm left to conclude that the one-day wonder - for it flamed, burned and went out in less than 24 hours - spoke more to the state of media malleability than it did to our drug laws.

The product of a think tank called Australia21, the basis for its call seemed to be little more than a round table at which a bunch of retirees talked about what they should have done about the drug problem when they had jobs that empowered them to do it - people such as former West Australian premier Geoff Gallop and former federal police commissioner Mick Palmer.

But for real detail on why drug law reform should not remove prohibition, have a look at Henry Ergas' column in the Australian, and (perhaps more importantly, since he links to his source material), his blog entry.

I had not realised that there were economists had considered the question in such detail. While I am generally suspicious of Ergas, as he appears to be climate change skeptic and has devoted much time to criticism of the Gillard carbon pricing scheme, his take on drugs is detailed and (it seems to me) well argued.

I would also point out that you can tell that the issue is a complicated one when you even get strong disagreement on the issue amongst the readers of soft Left blog Larvatus Prodeo.

[And here's news: when checking that LP link, I just saw that the blog is ceasing to exist. Quite a surprise, even though it had become pretty dull in the last couple of years.]

CO2 coming first and last

Shakun et al. Clarify the CO2-Temperature Lag

Skeptical Science has a good explanation here of the recent paper in Nature which looked afresh at the question of whether CO2 increases preceded or followed the start of the bout of global warming that ended the last glacial period 18,000 years ago.

Nothing coming from nothing critiqued

‘A Universe From Nothing,’ by Lawrence M. Krauss - NYTimes.com

Found via Not Even Wrong, this review attacking Krauss' key idea in his book ""Why There Is Something Rather Than Nothing" is well worth reading.   The key point:

Where, for starters, are the laws of quantum mechanics themselves supposed to have come from? Krauss is more or less upfront, as it turns out, about not having a clue about that. He acknowledges (albeit in a parenthesis, and just a few pages before the end of the book) that every­thing he has been talking about simply takes the basic principles of quantum mechanics for granted. “I have no idea if this notion can be usefully dispensed with,” he writes, “or at least I don’t know of any productive work in this regard.”

But you should read it all.

Snakes and spiders (or at least, snake and spider)

I got quite a surprise today when outside to see if the possum was home (in her hidey hole under the deck just outside the front door).    A rather large (well, about a metre, which is large enough) snake on the rocky garden bed spotted me before I spotted it, and shot off at high speed in front of my feet into the bushes.    Snakes going past me at a distance of 50 cm or less is too close for comfort, no matter what species they are.

The good thing, I suppose, is that  although it was out of sight very quickly, I did at least get to see that it was pretty much a uniform olive green colour, and looking at this website, I would be inclined to think it was a common green tree snake, which is non venomous.   Most of the dangerous snakes seem to have some pattern or banding on them, although the potentially dangerous yellow-faced whip snake seems devoid of pattern too.   In fact, now that I look at this other site, the whip snake seems a distinct possibility.  I mean, do green tree snakes end up on the ground very often? 

Despite living in this house for about 8 years now, with rather large bushes and trees in the front, and bushy neighbours’ gardens, as well as rats in the roof and (sometimes) seen in the back yard, this is the first snake of any kind I’ve ever encountered.  I’m sure they must be around, but out of sight out of mind is the best policy as far as snakes are concerned.

As for spiders, this one was sitting prominently in the sun this afternoon, and stayed still for a close up with my cheapish camera.  

The body colours remind me a bit of the patterns of Jupiter. (Just a little.):

It would appear to be a female St Andrews Cross spider.  Now you know.

Fear of white

A review of White Bread, a new book about our nation’s fear of flour. - Slate Magazine

What an interesting story told here about the history of white bread, and how it's been the subject of much condemnation well before my lifetime.  Some extracts:

 As Aaron Bobrow-Strain makes clear in his epically well-researched White Bread, our culture’s tendency to focus what we as individuals put in our mouths often goes along with classism and xenophobia. Just as whole wheat acolytes pity white-trash white-bread eaters, and gluten-free converts showcase their discipline through vegetables and lean proteins, so, too, did turn-of- the-century crusaders attempt to spread the gospel of good food to less enlightened masses.

Between 1890 and 1930, Bobrow-Strain writes, Americans transitioned almost completely from homemade bread to store bought bread—and specifically to bread made in large factories. Hygiene fears were a major reason. The emerging understanding of germ science led pure food crusaders to preach against the dangers of mother’s kitchen, which couldn’t hope to achieve the level of cleanliness of a large bread factory, nor the heat necessary to kill the “yeast germs.” “You and your little oven cannot compete,” one newspaper article informed women after the turn of the century. Scientists and food reformers also warned against mom-and-pop bakeries, whose reputation for substituting cheap substances like chalk and alum was further undermined by the presence of so many swarthy immigrant workers, whose hygiene was considered suspect.

White bread, untouched by human hands and carefully wrapped for hygienic transport, became a symbol of purity....

But during the '20s and '30s, the nation was gripped by panic over white bread. A wave of experts with questionable pedigrees began warning about white bread’s nutritional content, harkening back to the teachings of 19^th-century ascetic Sylvester Graham, who believed that refining wheat undermined God’s intent. (Graham had a number of interesting theories, including that consumption of meat, seasonings and rich foods lead to rampant masturbation.)

Dietician and radio show host Alfred W. McCann claimed that 400,000 children a year were sent to “little graves” because they were raised on white bread. Food pundits said that white bread could cause blindness and disfigurement. A 1912 article in a journal called “Life and Health” made the dubious claim that in countries where there was no white bread, there was no cancer. Bobrow-Strain writes that white bread was implicated in a slew of illnesses including “diabetes, criminal delinquency, tuberculosis … rheumatism, liver disease, kidney failure …” White bread’s fortunes sunk, and bakers, who preferred white flour in part because it was cheaper to mill and could be stored longer, were beside themselves.

The article goes on to explain that the food industry got pro-active, and by the 1940's, adding vitamins was one way they successfully fought against the anti-white cranks.   (Actually, as a child, I don't recall seeing any brand of bread advertising its additives, like they do now.  Maybe Australia never succumbed to fear of white bread?)

All very interesting.

More religion reading

I've been looking around for religious themed stuff for Easter.

Slate is having a hard time coming up with anything new. They have again posted a 2008 story on early Christian understanding of the resurrection, and I see that I linked to as a result of their 2010 re-posting of it.

I guess it is a bit of a challenge coming up with new ideas about it; unless, of course, you come up with something like the image on a cloth causing a whole misunderstanding. (See a few posts down below.)

In other religion stuff on the net, I see that Stephen Crittenden has been writing articles at the Global Mail website, and they are pretty good. One is a summary of the story about the forced resignation of Bishop Morris of Toowoomba (a story about which I have always had some trouble finding the details); and a somewhat more critical than I expected review of the troubled leadership of recently resigned Archbishop of Canterbury Rowan Williams. (Williams is only 61, I learned to my surprise. His eyebrows seem decades older than that.)

I only know of Crittenden because of his hosting the (now axed) Religion Report on ABC's Radio National, but I see from his Global Mail profile that his background is more in arts and culture generally. He's not snobbish about it, though, writing a piece about how much he likes the Simpsons. (He notes with approval some American analysis that points to the way it both satirises but re-affirms the nuclear family. As I have been watching it in re-runs a little more often lately, and catching up with episodes and evolving storylines over the years since I stopped regularly watching it, the number of times the show does this has been on my mind lately. I was also pretty surprised that the Simpson's Movie was so sympathetic to Flanders, given the degree to which he is routinely satirised for extreme religious conservatism.)

Anyway, I've strayed off religion haven't I...

How about this: a blog post from England about the question of why the Catholic Church still seems a little leery of cremation. However, given that, as with the writer of that post, I know of a Catholic Church with a newly installed columbarium (a place for keeping the ashes), it does seem that at the parish level, accommodation with cremation is being made (literally).

The world catches up with me

Hydrogen Storage Could Be Key to Germany's Energy Plans - Technology Review

I've asked this question years ago (it got a mention at this very blog in 2007):  couldn't you potentially get around the "unreliable base load" issue with large scale solar power (at least for plants built near a permanent water supply) by devoting a portion of the electricity being produced on a good sunny day to electrolysing water into hydrogen, storing it, and then burning it to get a gas turbine going for a rainy day?

Seems that it wasn't such a stupid idea after all:

If Germany is to meet its ambitious goals of getting a third of its electricity from renewable energy by 2020 and 80 percent by 2050, it must find a way to store huge quantities of electricity in order to make up for the intermittency of renewable energy.

Siemens says it has just the technology: electrolyzer plants, each the size of a large warehouse, that split water to make hydrogen gas. The hydrogen could be used when the wind isn't blowing to generate electricity in gas-fired power plants, or it could be used to fuel cars.

Producing hydrogen is an inefficient way to store energy—about two-thirds of the power is lost in the processes of making the hydrogen and using the hydrogen to generate electricity. But Siemens says it's the only storage option that can achieve the scale that's going to be needed in Germany.

Unlike conventional industrial electrolyzers, which need a fairly steady supply of power to efficiently split water, Siemens's new design is flexible enough to run on intermittent power from wind turbines. It's based on proton-exchange membrane technology similar to that used in fuel cells for cars, which can operate at widely different power levels. The electrolyzers can also temporarily operate at two to three times their rated power levels, which could be useful for accommodating surges in power on windy days. 

Some day my rightful place as CEO in charge of the Earth will be recognized by the planet, or at least aliens reading this blog who may have a better chance of installing me to that position.  They need to get a move on, though.

Improving mouse houses

Animal testing: Be nice to mice… | The Economist

Quite a charming report here with mouse information that's news to me:

Although medical science’s favourite critters relish temperatures of a little over 30°C, laboratories routinely keep them at five or ten degrees below that. This is not in order to torture the beasts but, rather, because when kept warm they are unmanageably aggressive. The downside is that they have to eat more than they otherwise would, in order to keep their bodies warm. That changes their physiology. And that in turn alters the way they metabolise drugs, with possibly confusing results.

The report then notes a study suggesting that labs don't have to increase temperatures to get them responding better to drugs; they just have to provide them with paper with which to build nests.   

Nice.

In the toilet

Hey, it's Easter, which always calls for its fair share of religion posts.

Does it count if it at least comes from Biblical Archaeology Review? Yes, that's enough of a connection for me. (The magazine is often pretty interesting reading, actually.)

Today I am recommending: First Person: Privies and Privacy

It's a quick look at some of the history of privacy while attending to one's daily toilet needs, and makes this observation:

We have long known that ancient notions of privacy are different from ours. But how different and in what ways remain far from clear. At several Roman-period sites, like Ephesus, Rome and Pompeii, archaeologists have found long benches with rows of adjacent toilet seats with no provision for privacy. What is less well known is that these provisions were not for the ordinary person but were for the elite.

Which leads me to another observation: The higher the social station, the less concern for privacy. Which brings me back to Eglon (and Henri III): Royalty was unconcerned with privacy. But the issue may not have been privacy at all. Royalty could do what it wanted. What might be distasteful for the average person was a prerogative of status. What would be offensive to or for the average person was permitted to royalty—indeed, may even have been a mark of privilege.

Well, that's interesting, when in the more modern setting, lack of toilet privacy is generally seem as something that de-emphasises privileged status. I remember as a child being surprised when watching the 1950's movie "No Time for Sergeants" on TV, which featured a key sequence involving a barracks latrine. The thing was, this was a row of toilet seats with no privacy screening at all; something which I thought was taking military group cohesion a little too far. (You can it on a short video clip here.) Attending to this in the field is one thing, but making barracks with no toilet privacy seems quite another.

In fact, while everyone is aware that no privacy while showering was long a feature of public swimming pools and sports locker rooms, I have never known of anywhere where there was a lack of privacy for defecation.

Anyway, this also reminds of a recent story from India, a country renowned for its lack of toilets:

New data from the country's 2011 census shows 59% of Indian households have a mobile phone. Only 47% have a toilet on the premises (and that includes pit latrines that don't use running water).

Lack of toilet privacy is certainly no sign of higher status in that country.

So ideas of privacy change. I wonder what ancient Romans would think of someone doing the equivalent of posting about their sex life on Facebook, or a newspaper column. It would be the equivalent of having a board in the public square where you could pin notices about it, I guess, and might have been thought of as rather unedifying. I hope so, anyway.

The odd explanations for the inspiration for Christianity

Mystery solved? Turin Shroud linked to Resurrection of Christ - Telegraph

I meant to post about this a couple of weeks ago but forgot. Now I see that Australian breakfast television is doing a story on it for Easter Sunday morning. How odd.

Anyhow, short version: Cambridge art historian believes the Shroud of Turin is authentically the shroud in which Jesus was buried, but:

It was, suggests de Wesselow, seeing the Shroud in the days immediately after the crucifixion, rather than any encounter with a flesh and blood, risen Christ, that convinced the apostles that Jesus had come back from the dead.

As The Telegraph link above further explains:

What the apostles were seeing was the image of Jesus on the Shroud, which they then mistook for the real thing. It sounds, I can’t help suggesting, as absurd as a scene from a Monty Python film.

“I quite understand why you say that,” he replies, meeting me half way this time, “but you have to think your way into the mindset of 2,000 years ago. The apostles did see something out of the ordinary, the image on the cloth.

“And at that time – this is something that art historians and anthropologists know about – people were much less used to seeing images. They were rare and regarded as much more special than they are now.

“There was something Animist in their way of looking at images in the first century. Where they saw shadows and reflections, they also saw life. They saw the image on the cloth as the living double of Jesus.

“Back then images had a psychological presence, they were seen as part of a separate plane of existence, as having a life of their own.”

How does this rank with other "out there" theories for what inspired the establishment of Christianity? I would say: better than "The Sacred Mushroom and the Cross", the very 1960's inspired idea that the whole Christ thing was (more or less) one big hallucinatory story spread by "magic mushroom" folk of the middle east. As Wikipedia notes about the author (and his book, which was pretty big in its day):

The reaction to The Sacred Mushroom and the Cross ruined Allegro's career.[3][4] His detractors considered his somewhat sensationalist approach deplorable and his arguments somewhere between unconvincing and ludicrous.

The "Shroud of Turin is the resurrection" theory I would also rank above Barbara Thiering's so-called "pesher technique" reinterpretation of the New Testament, which caught the imagination of a certain type of ABC religious types in Australia in the early 1990's. (I seem to recall her getting quite a run on shows hosted by Geraldine Doogue.) I have just found this handy summary of the deficiencies of the professor's theory from the New York Review of Books:

Professor Barbara Thiering’s reinterpretation of the New Testament, in which the married, divorced, and remarried Jesus, father of four, becomes the “Wicked Priest” of the Dead Sea Scrolls, has made no impact on learned opinion. Scroll scholars and New Testament experts alike have found the basis of the new theory, Thiering’s use of the so-called “pesher technique,” without substance. The Qumran pesher—the word itself means “interpretation”—is a form of Bible exegesis which seeks to determine the significance of an already existing prophetic text by pointing to its fulfillment in persons and events belonging to the age of the interpreter. Professor Thiering, by contrast, turns the sequence upside down, and claims that the authors of the New Testament composed the Gospel story so that pesher technique could subsequently be fastened to it.

So, it's a bit of a step up from those theories: at least it acknowledges Jesus existed, and doesn't rely on the Apostles being off their face on magic mushrooms every second day. But still, it ranks quite highly on the implausibility stakes.

Botanic gardens, Brisbane

Looking on the bright side, I guess...

Indian girls become child brides instead of prostitutes. - Slate Magazine

India is a country still, shall we say, in need of some social reform:

  India accounts for more than 40 percent of the world’s child-marriage cases, according to a recent UNICEF report. But, this wedding and betrothal ceremony is actually a welcome event. That’s because these girls are the youngest generation of the Saraniya community, a nomadic Indian tribe that had once traveled with the Maharaja, where the men had sharpened swords and made weaponry while the women had "entertained” the troops. When India achieved independence in 1947, the Saraniyas found themselves out of work, and for lack of options, returned to prostitution as a means to support their community.

Over time the community became dependent on the income from prostitution. Although the government had allotted the Saraniyas some land, the former entertainers didn’t know much about farming, especially daunting on land without water, working wells, or any sort of irrigation facilities. Faced with a drought and no work, the number of sex workers pushed into the hundreds as villagers recruited new girls into its fold at age 10 or 12. “If a daughter is not engaged or married by the time she’s 10 years old, she’ll be pushed into the flesh trade,” says Mittal Patel, secretary of Vicharta Samuday Samarthan Manch, an Ahmedabad-based NGO that works in the community. Often it’s the mothers who did the pushing, as the families were desperate for some income.

The solar system's GPS

How interstellar beacons could help future astronauts find their way across the universe

Maybe I've heard of something similar before, but what a neat idea:  using x-rays from pulsars as a sort of GPS system for spaceships travelling the solar system and beyond. 

Could be accurate to within a few km, according to the article.  Provided you're not trying to land your spaceship with it, that sounds pretty accurate.

Colebatch on cuts

Budget cuts will bring on recession

Tim Colebatch is one economics commentator who argues the Federal government's forthcoming budget cuts will hurt the economy rather than help it.  He notes Canada (with a conservative government) has resisted the call of the right wing to do otherwise.

We shall see what happens here, I suppose.

Will Republicans listen?

Shawn Lawrence Otto | A Message from a Republican Meteorologist on Climate Change

This is a really good plea from a Republican meteorologist for his party to stop denying climate change and be realistic about the issue.

No way back?

The news this morning is that the Federal Labor primary vote (according to the Nielsen poll) is back down to under 30%, with two party preferred at 43/57.

As far as I can tell there is no obvious reason for the large 7% (!) slump between this poll and the last. I guess there might have been some Queenslanders in the sample who felt they were on a roll and decided to punish Federal as well as State Labor, but who knows? I don't recall anything at the Federal level in the last month (apart from lingering resentment from the Rudd/Gillard fight?) which should cause this, and in fact most commentators seem to think Gillard looked more confident since winning that stoush.

Anyway, everyone seems to agree that Labor federally is facing a bit of a perfect storm. When the carbon "tax" is introduced and electricity prices go up, people will blame the government and ignore the compensatory measures. (Some of those are pretty significant though, so maybe the commentators are too pessimistic about that?)

And before that, the talk is of the government having to savagely cut back "middle class welfare" to get the budget back to surplus. This is, of course, something that conservative commentators, not mainstream economists, have been urging as a matter of utmost necessity. Yet what's the bet that cuts that are too deep will heighten the complaints that the two speed economy is causing middle class suffering, and the government will be perceived as causing more. I expect a huge amount of cynical posturing from the Coalition along these lines.

In fact, I'm not entirely sure I've ever heard what the government can do about this two speed economy issue. In some sectors, particularly tourism and parts of manufacturing, the high Australian dollar seems to be at the heart of the woes, and there's nothing to be done about that.

I guess that a world wide retreat from the threat of another financial crisis would help improve confidence generally, and signs of improvement in the US economy will too. The things the West does not need right now, I would guess, is an exploding Middle East (due to an ineffective attack on Iran by Israel with US support) or for China to undergo some uncontrolled economic crisis.

Anyway, the fact remains that with its budget, it seems the Labor government is at risk of both losing some support of mainstream economists for cutting too harshly and consolidating its incredibly low primary vote with the electorate.

Yet, it still seems to me that mainstream economists, both in the private sector and academically, have not thought this government has not done anywhere near a terrible job on the economy, and consider it to have been more a victim of circumstances beyond its control, contrary to the perceived views of the electorate. (Who, puzzlingly, still - in the face of all evidence to the contrary - seem to view Kevin Rudd as a saint who was knifed by the witch Gillard.)

It's a very strange time in politics, and while Federal Labor certainly has had its significant mistakes and mis-steps in the last few years (mostly under Rudd), it is being treated much worse by the public than it actually deserves.

By the way - I agree with Barrie Cassidy: Julia Gillard could have dealt with the carbon tax "lie" allegation much better than she did. She did not want to be branded as "tricky", and so said she would not quibble about whether a fixed carbon price leading to a carbon trading scheme is properly called a "tax". But given the huge amount of confusion in the public about this issue, she may as well have argued the point.

As an example of this confusion - Robert Manne last week in a lengthy critique of Labor said twice that Gillard had promised "not to introduce carbon pricing" during this term. This is just wrong, or at the very least very misleading, yet few people in the comments section following that article pulled him up on this.

Here is what was reported in The Australian on election eve:

In an election-eve interview with The Australian, the Prime Minister revealed she would view victory tomorrow as a mandate for a carbon price, provided the community was ready for this step.

"I don't rule out the possibility of legislating a Carbon Pollution Reduction Scheme, a market-based mechanism," she said of the next parliament. "I rule out a carbon tax."

This is the strongest message Ms Gillard has sent about action on carbon pricing.

While any carbon price would not be triggered until after the 2013 election, Ms Gillard would have two potential legislative partners next term - the Coalition or the Greens.

She would legislate the carbon price next term if sufficient consensus existed.

Now, she obviously started a scheme earlier than indicated by the story, there is no doubt about that, and the quibbling about what is and isn't a carbon tax can be had, but it is still extremely careless and wrong of Manne to represent the story this way:

.....having promised the electorate that her government had no intention of introducing a price on carbon, having scrambled back to government as the leader of a minority government - Prime Minister Gillard now signed an agreement with Greens for the creation of a parliamentary committee to broker the outlines of a carbon tax/emissions trading scheme.

So add that to the swirling mass of confusion and resentment that is the Australian electorate at the moment, and this situation does look pretty crook.

Climate change psychology

I see that Chris Mooney has written a book "The Republican Mind" that looks at the different character types of people who are attracted to the opposing conservative and liberal sides of politics. It is being discussed around the place in relation to climate change in particular.

This is an especially interesting topic, because until the last decade or so, I would not have said that conservatives (at least of the non-American variety) showed signs of being strongly anti-science. Even the Americans, with their significant chunk of disbelief in evolution in the population, still seemed easy convinced of science-y (or at least technological) things like the "Star Wars" laser defence system proposed by Reagan, and nuclear power generally.

But there is no doubt that AGW has changed this.

So, while I have long thought that that conservatives and progressives do tend towards some differences in character and world outlook, I am sceptical that this has much to do with the fierce resistance to accepting what mainstream science is saying on climate change. This blog post at the Economist discusses this, and the comments following it are well worth a read too.

In Australia, John Quiggin has noted the book as well. It is only a matter of time before it is discussed at the frequently embarrassing-as-an-advertisement-for-the-Right blog Catallaxy, but there will be virtually nothing of value said about the topic there by its regular crew.

Far from encouraging

Nankai quake scenario menaces Pacific coast | The Japan Times Online

They've been revising some estimates for potential future tsunamis in Japan, in light of last year's experience, and the results sound remarkable:

 Wide swaths of the Pacific coastline stretching from Honshu to Shikoku may be hit by tsunami over 20 meters high if a newly feared megaquake occurs in the Nankai Trough, a Cabinet Office panel warned Saturday.

The new warning comes after the panel revised its 2003 estimate to reflect new findings from the March 2011 earthquake and tsunami that devastated the Tohoku region's coastline last year.

The 2003 report said no areas would see tsunami higher than 20 meters. The updated report is based on the assumption that the earthquake will have a magnitude of 9.0.

The tidal waves generated by the Nankai Trough temblor would slam areas from Kanto to Kyushu, with waves of up to 34.4 meters likely in Kuroshio, Kochi Prefecture, and between 10 and 20 meters in parts of Shizuoka, Kochi and Miyazaki prefectures.

Urban areas of Tokyo would see tsunami up to 2.3 meters high, but the village of Niijima in the Izu Island chain, which is administered by Tokyo, could face deadly waves up to 29.7 meters high, the panel said.

A minor but amusing Bleat

For some reason, I particularly enjoyed James Lilek's most recent bleat, looking at a couple of old American advertising characters.

Well, except for Louie the Fly, I guess, but even he only appears on TV.)

For those with young daughters

Puberty Before Age 10 - A New ‘Normal’? - NYTimes.com

I didn't care for the start of this long article (telling of a mother trying out a quake alternative medicine guy to see why her daughter is undergoing very early puberty,) but apart from that, it's a good explanation of the phenomena.

I didn't realise this:

Now most researchers seem to agree on one thing: Breast budding in girls is starting earlier. The debate has shifted to what this means. Puberty, in girls, involves three events: the growth of breasts, the growth of pubic hair and a first period. Typically the changes unfold in that order, and the proc­ess takes about two years. But the data show a confounding pattern. While studies have shown that the average age of breast budding has fallen significantly since the 1970s, the average age of first period, or menarche, has remained fairly constant, dropping to only 12.5 from 12.8 years. Why would puberty be starting earlier yet ending more or less at the same time? 

I also didn't know that the differences between racial groups was so distinct:

Then in August 2010, the conflict seemed to resolve. Well-respected researchers at three big institutions — Cincinnati Children’s Hospital, Kaiser Permanente of Northern California and Mount Sinai School of Medicine in New York — published another study in Pediatrics, finding that by age 7, 10 percent of white girls, 23 percent of black girls, 15 percent of Hispanic girls and 2 percent of Asian girls had started developing breasts.

Pretty remarkable, and it also seems very difficult to work out exactly what is going on.

Anyway, its good of the NYT to put such lengthy magazine articles up. It remains, to my mind, one of the most generous media sites around.

The red knit cap explained

James Cameron’s deep-sea dive: What’s it feel like to go so deep underwater? - Slate Magazine

Director James Cameron successfully completed a 6.8-mile-deep dive to the most remote region of the ocean Sunday and was shown emerging from his submarine in a small knit cap. Jacques Cousteau’s red knit cap was a signature part of his look, which was aped by Bill Murray and his crew in the movie The Life Aquatic With Steve Zissou. Why do underwater explorers wear skullcaps?

Because it’s practically freezing down there. The water temperature at the bottom of the ocean usually hovers around 37 degrees Fahrenheit, and most deep-sea exploration vehicles don’t have climate control. Explorers tend to bring hats, gloves, long johns, and other warm layers, which they pull on as they descend and the temperature drops. Socks and caps are particularly important, as it’s coldest on the floor and ceiling of the submersible. Because of concerns over electrical fires, deep-sea explorers wear natural fibers like cotton and especially wool, which is fire retardant, instead of synthetic fabrics.

Deep-sea divers have been wearing skullcaps, also known as watch caps or seaman’s caps, since long before the adventures of Jacques Cousteau. He may have picked up the style from hard-hat divers—those 19^th-century explorers who wore big copper helmets—who favored red knit caps for decades. The character of Steve Zissou in The Life Aquatic wore an identical cap in homage to Cousteau.

The last unconquered lands

Madagascar mystery of how small group of Indonesian women colonised island

So it seems Madagascar has an odd anthropological history, with DNA research indicating this:

If the samples are right, around 30 Indonesian women founded the Malagasy population ''with a much smaller, but just as important, biological contribution from Africa'', it says.
The study focused on mitrochondrial DNA, which is transmitted only through the mother, so it does not exclude the possibility that Indonesian men also arrived with the first women.
Computer simulations suggest the settlement began around AD830, around the time Indonesian trading networks expanded under the Srivijaya Empire of Sumatra.

This gives me an excellent opportunity to note that the Revolver Maps gadget that you can see on the right hand side of my blog (the pretty rotating global showing the sources of hits to this website) has been here for quite a while now, and has shown hits from virtually all corners of the planet except Madagascar.

The Revolver globe can, incidentally, be enlarged by clicking on it so you can see that all continents have been conquered by this blog. But Madagascar has been sticking out like a sore thumb for me lately. It's big, I'm pretty sure it has more than cartoon characters living on it, and no one there has apparently ever ended up here despite my having mentioned the place at least 8 times since 2006.

What's a blogger supposed to do to get attention from an enormous island? Speaking of which, looking at Revolver again, I see that no one from Greenland has ever come here.

Surely that other big island has got a mention here? Yes, it looks like at least 17 times.

What is wrong with the people of Greenland and Madagascar? Do I have to mention them every second post to finally get a hit from them? Do I have to insult them, or praise them, to finally get someone to drop by?

I see that Greenlandic has become the official language of the icy island, but maybe I can get by with a Danish message:

Hilsner folk Grønland! Jeg ser frem til at dele en banket hvalspæk med dig, i hvert fald i cyberspace, men jeg vil hellere lade gæret fisk ud af menuen. Spiser du gæret fisk?

Af den måde, er det skandaløst, at Google translate endnu ikke dækker grønlandsk.*

As for Madagascar, I see it's Wikipedia entry is rather interesting, and it once had a king with an awesome name:

Upon its emergence in the early 17th century, the highland kingdom of Imerina was initially a minor power relative to the larger coastal kingdoms^[52] and grew even weaker in the early 18th century when King Andriamasinavalona divided it among his four sons. Following a century of warring and famine, Imerina was reunited in 1793 by King Andrianampoinimerina (1787–1810)

He was an unusual looking dude too:

Sort of looks like the ancestor of Weird Al Yankovic, actually.

Right: I've probably now committed an insult to a revered figure of Madagascar and teams of assassins are being despatched from the country right now. Please report this to Bob Carr if this blog suddenly goes silent.

* Greetings people of Greenland! I look forward to sharing a banquet of whale blubber with you, at least in cyberspace, but I would rather leave the fermented fish off the menu. Do you eat fermented fish?

By the way, it is outrageous that Google translate does not yet cover Greenlandic.

French mythology?

Wine and kids: Is it OK to let them try it? - Slate Magazine

This article notes that the French method of a gradual introduction to alcohol to kids at the family table did not actually lead to responsible adult drinking:

NPR recently aired a story looking at the rising incidence of binge drinking among French youths and growing doubts in France about the wisdom of giving children an early introduction to alcohol. What accounts for the upsurge in hell-raising? One possibility is that French parents have become more like us: They aren’t drinking nearly as much wine as they used to, and fewer children are being introduced to alcohol in the home. But here’s the thing: Early exposure has historically not encouraged moderation in France. Alcoholism has long been a major public health problem there. (In fact, the incidence of alcohol-related road fatalities got so bad that in the mid-1990s the government enacted some of Europe’s toughest drunk-driving laws.) The bottom line is that the seemingly more enlightened French approach hasn’t actually produced healthier drinking habits.

Oh. It was a French myth? Should I stop serving my kids sparkling apple juice in champagne glasses?

James Cameron’s Rocket Plunge to the Planet’s Deepest Recess - NYTimes.com

I don't care for James Cameron or his films, but I suppose I have to admit that he has the kind of rich man eccentric hobby that is at least interesting.  That is, he gets his own personal deep sea submersible built and ride it to the bottom of the deepest trench in the world.

This article shows the unique vertical axis design of the submersible, which has been built in Australia.  (Who knew we were good at that?  Pity we can't seem to do it quite so well with Navy submarine.)

He obviously does not suffer from claustrophobia:

Mr. Cameron plans to plummet 6.8 miles. The Challenger Deep is the most remote area of the Mariana Trench, the deepest of the seabed recesses that crisscross the globe. He is to cram his 6-foot-2 frame into a personnel sphere just 43 inches wide, forcing him to keep his knees bent and his body largely immobile. The dive plan calls for him to remain in that position for up to nine hours.

Better him than me.

Of course, if he disappears in the attempt to do this, it would form a great premise for a future Cameron-esque director to build on. Not that I wish him harm;  rich people who push technological limits are doing something better than making expensive but so-so movies.

Thomas, the Australian, and the "avoidable flood" that was unavoidable

Hedley Thomas is, predictably, crowing about the finding of the Queensland Flood Inquiry that the Wivenhoe Dam was not operated in accordance with the manual. It's true, his articles did mean the commission had to examine how the SEQWater report came to be written because (it would appear) lawyers missed the importance of some evidence relating to what dam release strategy the engineers thought they were operating on during the weekend of 8 - 9 January.

I haven't read all of the Inquiry's report on the engineer's evidence; but certainly, the way the SEQWater report was written was (as I indicted in a previous post), not a good look.

Whether the 3 engineers in question deserve any condemnation for it from a Crimes and Misconduct Commission enquiry is another question. The Inquiry found that the the Manual was pretty hopeless anyway, and I suspect that the fundamental problem with any such manual is that, by its very nature, flood management via dam releases must leave a wide scope of discretion in the engineers, at least until you get to a level where it's a case of "do anything to protect the dam."

And at the end of the day, what should matter is the degree to which, if any, dam operations actually caused any harm.

This is where Hedley Thomas and the Australian deserve no praise at all; quite the opposite in fact. The paper as a whole has followed a sensationalist line in its reporting, virtually since the flood occurred.

For example: this is what the Inquiry writes at Chapter 16, page 527:

It is unfortunate that there has been a conflation in some media reporting of two separate issues: whether there was non-compliance with the manual strategies and whether it caused unnecessary flooding. The Commission has found the first (see 16.11 Conclusions: the dam operations strategies.) As to the second, Mr Babister’s perception was that the flood engineers managed Wivenhoe Dam so that its flood mitigation effect was ‘very close’ to the maximum achievable within the constraints of the manual. That may well be right. The problem is that the possibility exists that because the engineers failed to consider the releases open to them within the parameters of the correct W strategy, an opportunity may have been lost for earlier releases.

The evidence was uniformly to the effect that the pattern of releases adopted on Saturday 8 January was appropriate: the lake level was only just over 68.5 metres and showed every sign of dropping; higher releases would have been risky and unwarranted. The picture is not so clear for Sunday 9 January, when the rainfall returned.

Was that opening line directed to Hedley Thomas? I think it pretty likely, given that this is what we get from Hedley Thomas (and Jamie Walker):

The Floods Commission of Inquiry's finding that the engineers who operated Australia's largest dam failed to adopt the correct strategy to protect Brisbane from inundation for about 36 hours from Saturday, January 8, last year, has given a major boost to the hopes of thousands of victims.

See the difference?

The Inquiry notes that, even though the dam manual was not followed from 8 am Saturday, no one thought the actual dam releases were at inappropriate levels during Saturday. The following paragraphs (at page 527 of the inquiry report) indicate that it was probably during the afternoon of Sunday 9 January that the change to faster releases could have happened:

Mr Babister initially said that ‘the more practical or realistic options if you were going to have higher releases, is to start some time after midday or somewhere between midday and 1600 hours. That’s when it would be realistic on the 9th to increase flows above what was released’; although he subsequently modified that view to say that the ‘only area’ that there was ‘some argument they probably could have released slightly higher flows’ was after 4.00 pm that afternoon. The scenario of higher releases on the afternoon of 9 January, Mr Babister said, was most closely reflected in scenario 9 of Figure 16.1; but it was ‘an adventurous risk-taking approach’ because it relied on confidence in the rainfall forecast.

Mr Shannon’s view was that given the ‘frightening’ inflow by 2.00 pm on 9 January and the predicted lake level it would be ‘extraordinary’ not to have put the closure of the bridges in train by then, in accordance with the intention of W3. And Mr Tibaldi volunteered in evidence that ‘decid[ing] to ramp up earlier for this event... would have reduced flood damage’. Mr Ayre agreed.

The chapter concludes:

That night [9 January], though, at about 7.00 pm, it was recognised that the release rate from Wivenhoe would have to be elevated. No actual strategy change was documented; at best, it can be said that the actions taken were consistent with strategy W3.

It follows that Wivenhoe Dam was operated in breach of the manual from 8.00 am on 8 January 2011 until the evening of 9 January 2011.

It therefore seems accurate to say that the Inquiry has only raised doubt about the actual rates of water releases for only 7 hours (from midday to 7 pm on 9 January) or even less.

Does anyone really think that 7 hours of faster release would have made a huge difference?

Does anyone reading the Australian or Hedley Thomas get any sense of that?

The Inquiry finds:

There is, it is obvious, plenty of scope for argument about whether adherence to the manual strategies would have made a difference to the way in which the flood engineers actually operated the dam; but the possibility certainly exists that they would have responded more quickly to the developing conditions of 9 January had their mindset been one of applying strategy W3. Ascertaining the practical result of acting more quickly also is subject to the uncertainties inherent in the modelling; but again, the possibility exists of at least some improvement in the flooding outcome for Brisbane and Ipswich.

Here's how Thomas interprets this:

Supreme Court of Appeal judge Catherine Holmes SC found that "the possibility exists of at least some improvement in the flooding outcome for Brisbane and Ipswich" if the dam had not been mismanaged. This is a departure from earlier findings made by the inquiry's expert witness, hydrologist Mark Babister, that the flood engineers had achieved close to the best possible result in mitigating the flood.

I don't see how it is a departure at all. As I understand it, Babister did not change his advice to the Inquiry between his two appearance - his modelling on different scenarios indicates that, for large parts of Brisbane, the flood might have been capable of being reduced by 30cm to a 90 cm (see page 526 of the report). The Inquiry notes the modelling has considerable uncertainties, and the scenarios they asked Mr Babister to model are not even all "realistic".

Of crucial importance is this paragraph - talking about what would have happened even if you started with the dam at 75% capacity:

It is important to note that even at these lower river heights, major flooding would still have been experienced in Brisbane. The Bureau of Meteorology defines a major flood as one which peaks above 15.5 metres at Moggill and 3.5 metres at Brisbane city1028 (the Port Office gauge). Scenario 4, which involved an initial lake level of 75 per cent of full supply level and W strategy trigger levels reduced by 25 per cent, resulted in a modelled height of 16.3 metres at Moggill and 4.0 metres at the Port Office.

To remind you,the measured height of this flood at the Port Office was 4.46m (although another gauge indicated only 4.27 m - see page 522 of the inquiry report).

So let's get this clear - the modelling of the independent hydrologist, based on starting at a dam 75% and with lower "trigger points" for releases would have resulted in a flood in Brisbane city of about 50 centimetres less.

Contrast this to what Hedley Thomas was writing on Feb 14 2011:

THE clearest official acknowledgment that the devastating flood in the Brisbane River was avoidable has been the decision yesterday to let go 25 per cent of the water stored in the Wivenhoe Dam.

Sorry, Hedley, Inquiry says "no".

Or what about the headlines given to his continual promoting of the idea that the dam management caused the flood:

• The great avoidable flood: an inquiry's challenge [22 Jan 2011]
• Engineer bores a hole in dam untruths [19 March 2011 - a piece promoting the engineer Michael O'Brien's figurings given the title "Brisbane Flooding January 2011: An Avoidable Disaster".]
  

And now:

• Damages to flow from Wivenhoe Dam breach [17 March 2012] even though the body of the report contains the caution from Maurice Blackburn lawyers: "If the action proceeds, it is likely to be the largest class action Australia has ever seen."

Thomas claims yesterday in a separate article:

The inquiry's expert witness had previously asserted that close to the best possible result was achieved; however, independent engineers consulted by The Australian have calculated that almost all of the flooding could have been avoided.

The detailed modelling necessary to determine this will be conducted by overseas experts engaged by law firms Maurice Blackburn and Slater & Gordon, which yesterday described the finding of the breach and the cover-up as "crystal-clear".

Well those "independent engineers" obviously aren't good enough for the Australian based litigation lawyers. In fact, if you look at Michael O'Brien's report, which Thomas was promoting in the report note above, O'Brien's work experience has been in building gas and oil pipelines, but he has had "to assess the impact of various rainfall events and to interpret and rely on flood mapping for the design and location of process facilities." Colour me unimpressed. His entire paper appears to be a mere series of "what ifs" in terms of when water might have been released if you had perfect knowledge of the rainfall that would arrive in the next few days, and is not (as far as I can tell) based on hydrological modelling at all.

Here's the thing: Hedley Thomas decided early to go hard with the story that this was a "preventable flood" that was the fault of dam operations. This was based on some hunches of a couple of engineers, and Thomas and the Australian has, in a long series of headlines and articles continued to foster this belief.

In reality, the Inquiry and the independent modelling it used has shown it was not an "avoidable flood" at all. Different timing of water releases may have made a relatively small difference to flood levels to most areas, but it still would have been a major flood even if you started at a 75% dam level and had lower triggers.

Given this scenario, my hunch is that it is rather unlikely that overseas modelling is going to be certain enough to allow for liability to be legally established for anyone. Certainly, the inquiry modelling would indicate that no one (in most of Brisbane, anyway) with more than about .5 m of water through their house is going to have any hope of blaming their damage on dam management.

The Australian, and Hedley Thomas, have been largely uninterested in reporting this level of detail of the Inquiry and its modelling, and have been more interested in campaigning for a interpretation of the event that actually isn't holding up to scrutiny. Personally, I think the the misunderstanding in large parts of the community that they have fostered for a year about the nature of the flood easily outweighs any benefit of having successfully made a few engineer's lives a further misery.

Finally, it's interesting too to note the connection between climate change skepticism (for which The Australian is well for promoting) and the "avoidable flood" meme. On both subjects, people like Andrew Bolt have been happy to promote the Thomas line without actually looking at the detail of the Inquiry. Same as his ignoring the fact that more intense droughts and floods have been predicted by CSIRO for years, Andrew Bolt has shown no sign of informing himself of the Inquiry's detailed findings as illustrated in this post.

Increasingly, I have been noticing how "pop" climate change skepticism thrives on laziness, and not looking into matters in enough detail. These "fake skeptics", as some call them, are easily conned in all sorts of ways, and The Australian is always there to help.

They never saw it coming...

It's not a volcano, it's a limnic eruption, with lots of dead animals below the carbon dioxide emitting crater lake in Africa.

(Year 6 "natural disaster" science project. It looks better in real life as the mist flows down over the huts. Dry ice is fun.)

Actually, I never knew that those cases of deadly lake out-gassing in Africa in the 1980's were called "limnic eruptions". My son found out about them on the net, and it's a more interesting thing to make than a plain volcano. I suspect he'll be the only limnic eruption in class.

Catalyst returns

In previous years, when Getaway used to be on Channel 9 on Thursday nights, watching attractive people have good holidays in beautiful parts of the world used to win out over watching Catalyst on the ABC. Now that Getaway has skulked away (I thought it had finished altogether, but it seems to be a half hour show on Saturdays now?) I should be able to catch Catalyst every week this year. Wait a minute - there's normally a child to pick up from Scouts on Thursday nights at 8.30. Dang.

Anyway - last night's Catalyst was really interesting.

The first story was about psychopathy and its childhood signs, and research projects aimed at whether it is possible to "re-wire" callous and unemotional children by the way their parents interact with them. That involves lots of getting the kid to look into their eyes, and telling them they love them. Apparently there was a paper published about this last year. Sounds kind of simple, and I would expect you would have to start really early, but it's an interesting idea.

The second story was about the difficulty in getting reliable communications with Antarctica, particularly the inland bases. I have wondered about this, because last year I unsuccessfully searched to see whether any researcher from that continent kept a regular blog. The reason is, it seems, that communications are currently via some rather old satellites in less than ideal orbits, and bandwidth to the place is therefore limited and not always reliable.

Australia is building a couple of microsatellites to fix this. They are really small (20 cm square!) but apparently will greatly improve communication to the place.

There is also this extended interview on the website in which the guy building the satellites is asked "how come these as so cheap, and the NBN satellites will be so expensive?)

And the final story was on a new, very cool, flight and motion simulator at Deakin university that looks like incredible fun to try out.

What a great show.

Space news times three

* Weightlessness may not be so good for the eyes and brain.

* Jupiter is good protection for Earth against some comets, but new simulations suggest it is not all that benevolent:

Jupiter’s role seems confused. It definitely sends asteroids and comets our way and, in any given year, more than 90 percent of all objects crossing Earth’s orbit are asteroids, so the protection Jupiter provides us from long period comets, or by eventually removing short period comets, is of lesser importance. Hence Jupiter is not the friend that it has been perceived to be. However, things could be far worse: were Jupiter to have a mere 20 percent of its mass, the impact rate would skyrocket. Obviously for any denizens on a planet in the target zone this is bad news, but in the grand scheme of things are impacts a positive or negative factor on the overall evolution of life on a planet across billions of years?

* Some scientists still have grand plans for a maglev rail track to space. The report sounds half plausible when it is talking about a cargo system (the track can run up the side of a mountain and cost about $20 billion - which is only a few years of NASA budget), but it sounds a bit loopy when it comes to the human rated system:

According to their plans, the Generation 2 magnetically levitated track would run about 1,609 km (1,000 miles) long, heading upward to an altitude of about 20 km (12 miles). While the track would be securely tethered to the ground, it would be held in mid-air completely by magnetic levitation. The entire track would be enveloped in a vented vacuum tunnel to avoid sonic shock waves that result from the spacecraft's hypersonic speeds of up to 9 km/sec (5.6 miles/sec). Once it exits this track, the spacecraft would be in position to reach LEO.

Sounds a tad implausible, no? But the guys talking about this (see the Startram website) are not nutters. Just wildly optimistic, by the sounds.

More smart rat news...

Rats match humans in decision-making that involves combining different sensory cues: study

Here at the Dominion of Opinion, we* like to note news showing about the intelligence of rats:

A Cold Spring Harbor Laboratory (CSHL) study that compared the ability of humans and rodents to make perceptual decisions based on combining different modes of sensory stimuli—visual and auditory cues, for instance—has found that just like humans, rodents also combine multisensory information and exploit it in a "statistically optimal" way -- or the most efficient and unbiased way possible.

Apparently, this is significant for further studies of autism, in which people combine sensory information in a not normal sort of way.  Unfortunately for rats, this sounds rather like their brains going under the microscope more often than before.   If they were really smart, they would start to act dumb during some of these tests.

Nuclear pessimism

Nuclear power: The dream that failed | The Economist

In any country independent regulation is harder when the industry being regulated exists largely by government fiat. Yet, as our special report this week explains, without governments private companies would simply not choose to build nuclear-power plants. This is in part because of the risks they face from local opposition and changes in government policy (seeing Germany’s nuclear-power stations, which the government had until then seen as safe, shut down after Fukushima sent a chilling message to the industry). But it is mostly because reactors are very expensive indeed. Lower capital costs once claimed for modern post-Chernobyl designs have not materialised. The few new reactors being built in Europe are far over their already big budgets. And in America, home to the world’s largest nuclear fleet, shale gas has slashed the costs of one of the alternatives; new nuclear plants are likely only in still-regulated electricity markets such as those of the south-east.

They do go on to mention that small, modular nuclear might make a difference, but there is not a market for it yet.

Right wing ghosts, and more

I don't read Ace of Spades, although a lot of right wingnut types seem to.

But I do check in on Michael Prescott, and he noted this entry at Spades in February about how the blogger is convinced the house he has just left was haunted by an obnoxious ghost.

Interesting.

This also reminds me, I was talking to a friend on the weekend about the conflict between Freud and Jung, and how the former saw his task as one involving a crucial cultural fight against "the black tide of mud" - occultism. Jung couldn't accept this: he was always interested in paranormal stuff. One of his early studies was to do with a spiritualist medium. He went on to be too interested in too many esoteric things, though, for my taste, and his thinking about it always seemed to be too woolly. Still, I have much more sympathy for his approach than that of Freud.

What I forgot to mention in my Saturday night conversation was that the current version of the purely scientific materialist view of the universe that most people hold is actually pretty fragile when you think about it. I mean, if you have just one personally convincing paranormal experience, this "black swan" of an event should really shake up your idea that only white swans exist.

Of course, people could always dismiss the event as a trick of the mind, and some are no doubt easily dealt with that way. (Sounds in the night are easily mis-interpretted, as are fleeing glimpses of movement and light.) But living in a house that seems persistently haunted, particularly with things involving physical movement, like lights being turned on when it was clearly impossible for a person to have done it (which Ace of Spades seems to be saying happened) - wouldn't that be a "black swan" for most diehard materialists?

I've never had a black swan experience myself, and it's kind of a sad thing that a person like me who would love to have one seems to repulse any hint of the paranormal. But who knows, it could happen yet.
