Mini black holes still unclear

2012-01-29T23:49:00.002+10:00

It appears that the question of whether the LHC will create mini black holes is still open, with a recent paper at arXiv about what signals a remnant particle from black hole decay might look like. The paper contains this paragraph in the introduction:

It is important to recall that the end-stage of the BH evaporation remains an open issue (see,e.g., Refs. [14, 15, 16]), because we do not yet have a con rmed theory of quantum gravity. In fact, the semiclassical Hawking temperature grows without bound, as the BH mass decreases, which can be viewed as a sign of the lack of predictability of perturbative approaches. This is an important issue also on a purely experimental side, since deviations from the Hawking law for small BH mass(near the fundamental scale MG ) could actually lead to detectable signatures.

An optimistic kind of story...

Morgellons disease: the CDC study that debunks the skin ailment.

Slate notes:

...now the CDC’s report is out, and Morgellons activists are horrified: The study, carried out in Northern California, found no environmental or infectious cause, nor evidence of real parasites. The fibers, which many Morgellons patients have insisted were of composed of a substance that was unidentifiable by any lab, were mostly just pieces of fabric and skin fragments from repeated scratching. (You can read the full study on the Public Library of Science.) In conclusion, the CDC writes on its “Unexplained Dermopathy” page,

This comprehensive study of an unexplained apparent dermopathy demonstrated no infectious cause and no evidence of an environmental link. There was no indication that it would be helpful to perform additional testing for infectious diseases as a potential cause. Future efforts should focus on helping patients reduce their symptoms through careful attention to treatment of co-existing medical, including psychiatric conditions, that might be contributing to their symptoms.

I still have this itchy left shoulder blade, though...

Is there anything we need on the moon? | FP Passport

Newt Gingrich seems to be reviled by a considerable number of people who have worked with him in the past, so one has to doubt that he really has any chance of being the Republican candidate for President. (On the other hand, this didn't stop Kevin Rudd - but Newt doesn't have a regular slot on a high rating breakfast show in which to appear all smiley and blandly "safe".)

Anyhow, about the only thing about him which should appeal to me (his grandiose plan to get a permanent colony on the Moon in a very short time) has been much ridiculed as ridiculous and pointless.

As I have said before, I am keen on a permanent Moon base as being at least a sort of 'life raft" for life and knowledge from the Earth, but people want more immediate and profitable reasons for going there. Lunar mining is one thing that doesn't get discussed much, but the Foreign Policy article linked above has some suggestions about what's there and what might eventually be worthwhile mining in future.

I just wish the more gradual, and realistic, Bush program for a lunar return had not been dumped by Obama.

Courting male mice sing like birds

What a charming story:

Male house mice sing like birds to serenade their mates, a study has found.
But don't expect to catch a performance in your kitchen - their high-pitched soprano voices are beyond the range of human hearing.
Austrian scientists made the discovery after slowing down the ultrasonic courtship calls of mice to study them. They found that mouse music bore a "striking" similarity to birdsong.
The vocalisations were complex and personalised, containing "signatures" that differed from one tiny crooner to another. Until recently, it was assumed the sounds made by male mice were no more than high-pitched squeaks.
Previous studies by the same group confirmed that male house mice sing when they pick up a female's scent, and that females are attracted to their songs. Females were able to distinguish between their own brothers' songs and those of unrelated males, even when hearing their siblings sing for the first time.

How Neutrons Might Escape Into Another Universe - Technology Review

Can't say I've heard this before, but it seems the suggestion has been made that neutrons might just be able to do a leap to another brane. That is, another universe.

OK, we don't just need it to be neutrons; we need it to be information. The future of intelligence could thus be guaranteed, no matter the fate of the particular universe it finds itself in. (Well, I'm being optimistic in a science fiction-y way, here.)

Salmon cakes for future reference

As this blog has come to serve as a sort of on line diary/journal for things I don't want to lose, like recipes, I'll note a salmon fish cake recipe here so I don't forget the quantities again:

Boil or steam 500 g of potatoes. Finely dice about one stick of celery, maybe half a big salad onion, and finely grate some carrot. Drain potatoes very well and mash then up a bit. Add the other vegetables, some salt and pepper, and a drained 415 g can of salmon. Let it all cool down a bit, and add one egg. Mix it all up well, and use another beaten egg and breadcrumbs to make patties from the mix (makes about 8). The mix is a bit soft - it needs to be left in the fridge to firm up a bit. Fry in about a centimetre of olive oil. Nice. I think if serving for adults, a bit of chilli would not go astray too.

BBC News - Asteroid to make near-miss fly-by

An asteroid will pass by the Earth on Friday in something of a cosmic near-miss, making its closest approach at about 1600 GMT.
The asteroid, estimated to be about 11m (36ft) in diameter, was first detected on Wednesday.
At its closest, the space rock - named 2012 BX34 - will pass within about 60,000km of Earth - less than a fifth of the distance to the Moon.....

Earlier estimates put the asteroid's closest distance at as little as 20,000km, near the distance at which geostationary satellites reside, but observations by observatories overnight showed it will pass at a more comfortable distance.

Just goes to show what I noted in 2010 - small, city killing asteroids may turn up suddenly and there isn't much we can do about it.

Update: from a 2008 Scientific American article:

Improved telescopes would identify an estimated one million near-Earth objects over the next decade to 15 years, and 8,000 to 10,000 of them will have some probability of hitting the planet, Schweickart says. A hit by even one of the smaller rocks, say the size of a convenience store, would have the impact of 400,000 Hiroshima nuclear bombs exploding at once, he says.

Isn't it odd how little publicity such a close passing potential disaster attracts in the media?

Tents and aborigines

2012-01-27T09:05:00.001+10:00

Tim Blair summaries the Australia Day incident with the PM accurately, although with more light heartedness than I might have expected. Andrew Bolt takes the more serious route, but I personally think his previous deliberate snideness in dealing with the difficult issue of who can or should claim aboriginality has forever weakened his credibility as a public commentator on the issue. (Of course, the relatively pale skin of many involved yesterday will be taken by many as vindication of his criticisms. The point is, however, that Bolt could have made the criticism without any legal trouble if he had been more careful and didn't throw in attempts at personal ridicule.)

In any event, there is no doubt at all that, by my reckoning, 95% of the population will rightly see it as a disgraceful incident and it will harden a huge number against any further symbolic or legal steps towards greater recognition of aborigines.

Anyone on the Left who tries to argue it was all the police fault, or even Tony Abbott's fault, deserve ridicule.

BBC News - Fried food 'fine for heart' if cooked with olive oil

Eating fried food may not be bad for the heart, as long as you use olive or sunflower oil to make it, experts say.

They found no heightened risk of heart disease or premature death linked to food that had been cooked in this way....
In an accompanying editorial, Professor Michael Leitzmann from the University of Regensburg in Germany said: "Taken together, the myth that frying food is generally bad for the heart is not supported by available evidence.

"However, this does not mean that frequent meals of fish and chips will have no health consequences.

"The study suggests that specific aspects of frying food are relevant, such as the oil used, together with other aspects of the diet."

This is all well and good, but I still get a bit sick of chips being the universal accompaniment to most cheaper cafe/pub meals.

A trio of climate change

2012-01-26T12:21:00.002+10:00

Three papers that caught my eye:

* Injecting sulfate particles into stratosphere won't fully offset climate changeAccording to the study, injecting sulfate into the atmosphere may cool the tropics and keep them cooler, but it wouldn't have so much effect on the polar regions. Hence sea level rise continues, I suppose. But they also point out that there could well be "surprises" from the whole enterprise. The key point is that it is no panacea to climate change:

"There is no way to keep the climate the way it is now. Later this century, you would not be able to recreate present-day Earth just by adding sulfate aerosols to the atmosphere," McCusker said.

* Cosmic rays not looking convincing: A decade long study of solar related galactic cosmic ray flux indicates no co-relation with clouds:

We identify no statistically significant correlations between cloud anomalies and TSI/GCR variations, and conclude that solar related variability is not a primary driver of monthly to annual MODIS cloud variability. We observe a net increase in cloud detected by MODIS over the past decade of ~0.58 %, arising from a combination of a reduction in high – middle level cloud (−0.31 %) and an increase in low level cloud (of 0.89%); these long term changes may be largely attributed to ENSO induced cloud variability.

Skeptics who dream about cosmic rays being the secret influence which hasn't yet been credited in climate change seem to be losing an argument, yet again.

* "Missing energy" not really missing at all? A new study indicates that there's enough uncertainty in ocean heat measurements that the energy that Trenberth said was "missing" may not be missing at all:

Here we present a revised analysis of net radiation at the top of the atmosphere from satellite data, and we estimate ocean heat content, based on three independent sources. We find that the difference between the heat balance at the top of the atmosphere and upper-ocean heat content change is not statistically significant when accounting for observational uncertainties in ocean measurements³, given transitions in instrumentation and sampling. Furthermore, variability in Earth’s energy imbalance relating to El Niño-Southern Oscillation is found to be consistent within observational uncertainties among the satellite measurements, a reanalysis model simulation and one of the ocean heat content records. We combine satellite data with ocean measurements to depths of 1,800 m, and show that between January 2001 and December 2010, Earth has been steadily accumulating energy at a rate of 0.50±0.43 Wm⁻² (uncertainties at the 90% confidence level). We conclude that energy storage is continuing to increase in the sub-surface ocean.

Judith Curry, the Uncertainty Queen of climate change scientists, thinks comments made by Trenberth about this are some sort of quasi vindication of her "ooh, it's all so uncertain we shouldn't be doing anything yet" stance, and there is a long thread that starts with her snark as follows:

If Kevin Trenberth is concerned about the uncertainties then he should stop ranting about deniers.

Exaggerating uncertainty to defend your own scientific papers from criticism, and then turning around to denigrate as a “denier” anyone who is uncertain and questions the IPCC’s overconfident assertions, is hypocritical IMO.

And Chris Colose comments further down about Curry:

She doesn’t seem to be able to grasp that large uncertainties in some area do not preclude high confidence in others, or may not even be relevant to others. She continues on her philosophical rants about ‘uncertainty’ while not publishing a specific scientific example that has withstood criticism (e.g., Hegerl et al’s response to her “monster” paper). Nor does she seem to realize that just making stuff and saying “things are uncertain!” is not useful contribution, and coupled with many other scientific sins is the reason for the label “denier,” not the observations that science isn’t perfect. You can’t throw 100 darts against the wall, hope one sticks, and say “see, told you!”

Andrew wrong a year ago: still wrong today

2012-01-25T08:55:00.001+10:00

It was almost exactly a year ago, after the Queensland floods, that Andrew Bolt had a post up alleging that a 2009 report by the Queensland Office of Climate Change had only mentioned drought, not floods. He was following the lead of another blogger who had originally made the claim.

As Tim Lambert pointed out (as I previously noted here) this was simply wrong: the claim related to one chapter of the report only. In fact, the report said that intensification of individual rainfall events in South East Queensland was predicted in at least one paper, even if overall there may be less rainfall in future over most of Queensland :

Climate change is also likely to affect extreme rainfall in south-east Queensland (Abbs et al. 2007). Projections indicate an increase in two-hour, 24-hour and 72-hour extreme rainfall events for large areas of south-east Queensland, especially in the McPherson and Great Dividing ranges, west of Brisbane and the Gold Coast. For example, Abbs et al. (2007) found that under the A2 emissions scenario, extreme rainfall intensity averaged over the Gold Coast sub-region is projected to increase by 48 per cent for a two-hour event, 16 per cent for a 24-hour event and 14 per cent for a 72-hour event by 2070. Therefore despite a projected decrease in rainfall across most of Queensland, the projected increase in rainfall intensity could result in more flooding events.

Did Andrew ever acknowledge such an error in his post? Not as far as I can see. In fact, he posts and moves on; just in the same way he never acknowledged at his blog that Anthony Watts' own paper proved his claims about the US temperature record being largely due to bad siting of weather stations.

So, today, after a couple of days of intense rainfall in South East Queensland, what do we find Andrew Bolt posting about again today? Yes - "warmists" never predicted heavy rain and floods as a part of global warming.

No Andrew, this is not right. Here is another paper from 2007, at the height of the drought (which, incidentally, was likely itself record breaking - there was a paper about this I have linked to before, and I'll track it down later) which concluded that all models showed:

Australia shows a shift towards warming of temperature extremes, particularly a significant increase in the number of warm nights and heat waves with much longer dry spells interspersed with periods of increased extreme precipitation, irrespective of the scenario used.

It is hard to credit Bolt as having any honesty at all in this debate when he never corrects his claims.

The visible hand | The Economist

This will go over well at Catallaxy. The Economist has a quasi sympathetic look at the success of "state capitalism," as demonstrated by China, Brazil and elsewhere:

This special report will cast a sceptical eye on state capitalism. It will raise doubts about the system’s ability to capitalise on its successes when it wants to innovate rather than just catch up, and to correct itself if it takes a wrong turn. Managing the system’s contradictions when the economy is growing rapidly is one thing; doing so when it hits a rough patch quite another. And state capitalism is plagued by cronyism and corruption.

But the report will also argue that state capitalism is the most formidable foe that liberal capitalism has faced so far. State capitalists are wrong to claim that they combine the best of both worlds, but they have learned how to avoid some of the pitfalls of earlier state-sponsored growth. And they are flourishing in the dynamic markets of the emerging world, which have been growing at an average of 5.5% a year against the rich world’s 1.6% over the past few years and are likely to account for half the world’s GDP by 2020.

State capitalism increasingly looks like the coming trend. The Brazilian government has forced the departure of the boss of Vale, a mining giant, for being too independent-minded. The French government has set up a sovereign-wealth fund. The South African government is talking openly about nationalising companies and creating national champions. And young economists in the World Bank and other multilateral institutions have begun to discuss embracing a new industrial policy.

The Economist comments are often worth reading too, and this one caught my eye:

The problem is that the Western liberal capitalism, that developed our society, has transformed paradoxically into communism. The welfare state is really a form of communism that prune and obstruct the tradicional liberalism that became western contries leaders of the world.

If you create a huge free public health system, a three years unemployment coverage, a free educational system, a grants culture or compel successful workers to pay 56% income tax, you really has establish a communism regime where talented people have to support others without any merit more than to be human beings.

Yes, what a tragedy that is!

BBC News - Big Tokyo earthquake likely 'within the next few years'

A big earthquake is much more likely to hit the Japanese capital, Tokyo, in the next few years than the government has predicted, researchers say.

The team, from the University of Tokyo, said there was a 75% probability that a magnitude 7 quake would strike the region in the next four years....
Researchers at the University of Tokyo's earthquake research institute based their figures on data from the growing number of tremors in the capital since the 11 March 2011 quake.

They say that compared with normal years, there has been a five-fold increase in the number of quakes in the Tokyo metropolitan area since the March disaster.

The Republicans’ new voodoo economics - The Washington Post

I was asked over the weekend why I had started saying that it seemed to me that the Right in America had re-adopted a form of "voodoo economics".

I don't think I knew that an economics editor from The Economist had written an article in August with this very title, and I link it here for future reference.

Update: Slate looks at how Gingrich's tax reform proposals are marginally different from those of the other Republicans. But it points out:

Every single candidate from the wacky Herman Cain to nice guy John Huntsman is running on the premise that taxes should be reduced relative to current policy, especially on high-incomes and on investment income. Gingrich is no exception to that rule as this chart based on Tax Policy Center analysis will show:

One respect in which Newt stands out from the pack somewhat is that essentially everyone's taxes go down at least a little under the Gingrich Plan. Most of the Republican contenders are currently preparing to raise taxes on a large number of lower income families who benefit from what are called refundable tax credits.

But as the first comment following the article notes:

I don't think anyone really believes that Gingrich et al are even pretending to look after "the 99%". How can someone simultaneously shriek about the deficit, openly plot a bloody, senseless, and expensive war, and propose steep tax cuts for everyone? You would think that someone who wanted to shrink the deficit or take a bite out of the debt would keep both massive spending cuts and tax hikes on the table.

Why there is no point in my going to literary festivals

2012-01-22T11:51:00.000+10:00

Michael Hayworth, a publisher, complains in a column in The Age today that Australian "classic"novels are forgotten all too quickly by both academia and the public, and many are out of print. But he starts with this observation:

We live in the world of the home-grown literary bestseller, the world of The Slap and The Secret River. We love our new stars, and celebrate the success of Favel Parrett or Toni Jordan or Craig Silvey. Our writers have careers both at home and abroad. We no longer expect our life-changing books to be written in isolation and despair, against the odds, fulfilling what Henry Lawson came to believe was the destiny of the Australian writer.

OK, well, I've heard of The Slap because it became a TV series last year that didn't sound all that interesting, and I therefore didn't watch. I have heard the title "The Secret River". I think.

But, sorry, call me completely out of touch with Australia literature if you want, I have not heard of Favel, Toni or Craig. And I even watch First Tuesday Book Club about half the time its on. [Now that I think of it, I can't remember the name of any Australian author who I saw on it last year, except for potboiler thriller writer Matthew O'Reilly (who I also haven't read.) Maybe I only watch the show because I like it when they strongly disagree on the merits of something I'm never going to read anyway.]

Back to Hayworth:

Our universities have failed for more than a century to create any kind of enduring tradition for the teaching of Australian literature. We are so familiar with this failure we hardly notice. And our publishing has always been dominated by British houses, which have not always felt the need, simply because a book is part of our national heritage, to keep it available.

In 2011, in not a single course in the whole country were students asked to read Henry Handel Richardson's The Fortunes of Richard Mahony. This is the equivalent of not one Russian university teaching Anna Karenina, of Madame Bovary going untaught in France.

There you go: another Australian author and book, this one a "classic" apparently, which I haven't heard of.

But hang on a minute: "failed for more than a century to create any ...enduring tradition..." is a bit rich isn't it? By 1900, the country had only been around in any substantial form for a few decades. (Have a look at this chart, which indicates the white population in 1843 was barely 250,000.) Sure, Sydney University was founded in 1850 (presumably with very small class sizes,) but people coming here were hardly motivated by the weather making it a nice place in which to write books, and it's hard to imagine University courses of the early 20th century being designed around the works of Henry Lawson (or some such.)

In any event, I'm not entirely sure why Universities need to "teach" modern literature at all, but that's just me a being a not-very-arty philistine, I suppose; even though readers of this blog may think I am more "arts" inclined that I really am due to my reports on the latest weird installations at Brisbane's GOMA. I can see the value in studying (as opposed to merely experiencing) literature from the point of view of what it tells us about societies' and individual's attitudes in the past, and the arc of their development over time; this applies especially to really old literature. But the study of modern literature when there is plenty of other material around about the society it was written in; well, after the first 5 years of analysis of a particularly complex book, I am not entirely sure what more there is to be said or taught, and you could probably now find most of that analysis for free on the net instead of going to university.

Anyhow, Hayworth's complaint about good Australian books being out of print would, one expects, be answered by the increasing use of e-readers. Surely it can't be very expensive to put them out in electronic format, and even develop a specialised field of advertising for formerly acclaimed books which have been out of print for some years.

If the publishing industry can't work out how to do that, Andrew, I'd say it's pretty much their own fault, and I wouldn't blame it on Universities at all.

About that fridge...

2012-01-18T22:48:00.000+10:00

George Lucas Is Ready to Roll the Credits - NYTimes.com

This New York Times article is largely about a new George Lucas produced film "Red Tails," which (to his chagrin) he had to finance personally. It sounds potentially good - an old fashioned patriotic film about the (black) Tuskegee Airmen, featuring a lot of aerial footage. And, importantly, it's not actually directed or written by Lucas.

The article also spends a lot of time reviewing Lucas' career, and the enemies he has made with fanboys who hate him fiddling with his Star Wars films gets much coverage.

But the other great controversy of his movie making career - the much derided "nuking the fridge" segment from the much derided Indiana Jones and the Kingdom of the Crystal Skull - is what I want to note.

I cannot believe how much venom is directed at that film. It was mentioned in at least half of the Tintin reviews I read, usually reading something like "this is a much better Spielberg action film than that last embarrassment of an Indiana Jones film." Well, I beg to differ.

I didn't think IJKCS was wonderful: I thought the script could have been much better, and, yes, OK, it was the silliest Indiana Jones film with some of the fake stunts, but there were enough well done sequences and images that I still ranked it as being enjoyable enough.

So, how did "nuking the fridge" manage to not offend me? I mean, sometimes really stupid science puts me off an entire movie. (The villain needing a satellite dish the size of Arecibo radio observatory to get a message to an orbiting satellite weapon in Golden Eye is the example I remember most frequently.) So what about the fridge? My reaction was that it was extremely unlikely and therefore a bit silly, but not fundamentally impossible. I now have information to back up that view.

The NYT notes (and I had heard this before) that Steven Spielberg claimed in one interview that it was his "silly idea". However, Lucas tells the paper that this was just Spielberg trying to be nice:

When I told Lucas that Spielberg had accepted the blame for nuking the fridge, he looked stunned. “It’s not true,” he said. “He’s trying to protect me.”
In fact, it was Spielberg who “didn’t believe” the scene. In response to Spielberg’s fears, Lucas put together a whole nuking-the-fridge dossier. It was about six inches thick, he indicated with his hands. Lucas said that if the refrigerator were lead-lined, and if Indy didn’t break his neck when the fridge crashed to earth, and if he were able to get the door open, he could, in fact, survive. “The odds of surviving that refrigerator — from a lot of scientists — are about 50-50,” Lucas said.

I wonder who those scientists are?

Anyway, that's enough for me. My gut reaction was about right, and Crystal Skull haters will just have to concentrate on the vine swinging scene instead. (Hey, that wasn't fundamentally impossible, either.)

Whatever happened to Spielbergian aliens?

2012-01-18T07:45:00.002+10:00

The two big science fiction-ish hits of Steven Spielberg's early career, Close Encouters and ET, were notable for the niceness of the aliens: little squishy botanist ET wouldn't harm a fly; and although the CE3K aliens appeared to have no concept of how disorientating it may be for humans to be sucked up into a mother ship and returned to their families 60 years later, they were touchy feely nice guys in the end. No alien's perfect, I guess: ET may well have turned rapidly into an alcoholic if he could have tolerated family absence better.

So, while watching Cowboys and Aliens on DVD last night, which Spielberg executive produced, I wondered why he now only seems to be involved with films showing aliens that want to swash humans like so many bugs.

His own War of the Worlds showed physically weak looking aliens who nonetheless thought humans were the most convenient source of blood and bone fertiliser for the lawn; last year's exec produced Super 8 had an alien that was (if I recall correctly) being treated unfairly, but nonetheless was ultra violent in response; and now Cowboys and Aliens had another set of grotesque designed aliens who, despite having the technology to come to Earth in a pretty cool looking spaceship, thought the best way to dispose of interfering mammals is to bite their neck out or stab and slash them with their built in dagger fingers.

Doesn't anyone write science fiction with nice aliens any more?

As for Cowboys and Aliens as a movie: the critical response was about right - not great, not horrendous, but had a bit of a feel of a lost opportunity to do a cool genre mash up better.

Actually, the post is about Original Sin again.

Now, it is quite possible that I have read about this particular translation issue before, but have forgotten it. Nonetheless, this translation issue was noted in a book I picked up at the Lifeline Bookfest yesterday (yes, Brisbane people - you have until next weekend to load up on books you probably won't finish before the next one comes around), but a simpler explanation is to be found via Google books, which turned up this extract from Hans Kung book "Great Christian Thinkers":

One other thing occurred to me about this - and I presume this is not an original thought - until Catholic scientist priest Spallanzani, who I mentioned here several posts back - did his 18th century work, mammalian reproduction as requiring both ovum and sperm was not well understood, and the idea that semen alone contained a tiny human just waiting to be planted and grow up was one way of understanding it. Logically, then, there was a sense in which one man's seed also contained all the future babies as well as his own.

Would such thinking contribute to the way in which Augustine might have thought all humans were "in" Adam, and (in a sense) were quasi-participants in the original sin?

Update: Another book (Augustine of Hippo - a life" by Henry Chadwick ) notes the following, which seems relevant to my speculation:

Update 2: It may not have been Augustine's idea, but we do find in the Wikipedia entry for homunculus that some later thinkers thought that "preformationism" was relevant to original sin:

It was later pointed out that if the sperm was a homunculus, identical in all but size to an adult, then the homunculus may have sperm of its own. This led to a reductio ad absurdum with a chain of homunculi "all the way down". This was not necessarily considered by spermists a fatal objection however, as it neatly explained how it was that "in Adam" all had sinned: the whole of humanity was already contained in his loins.

Actually, the Wiki entry on preformationism is worth looking at too, for a more detailed look at its development in philosophy and its lasting influence. It all starts with Pythagoras, apparently. When microscopes came along, the dutch inventors gave preformationism a boost by claiming to see (in a fashion which reminds me of how, much later, Martian canals would be imagined via telescopes) things in semen that simply aren't there:

Dutch microscopist Antonie van Leeuwenhoek was one of the first to observe spermatozoa. He described the spermatozoa of about 30 species, and thought he saw in semen, "all manner of great and small vessels, so various and so numerous that I do not doubt that they be nerves, arteries and veins...And when I saw them, I felt convinced that, in no full grown body, are there any vessels which may not be found likewise in semen." (Friedman 76-7)^[7]

But, going back to Augustine, it would seem that he does not really count as a preformationist:

St. Augustineand St. Thomas Aquinas both held that hominization, or the coming intobeing of the human, occurs only gradually. Quickening was thought tooccur around 40 days, and to be the point at which the merely animalmix of material fluids was ensouled. Until 1859, when Pope Pius IXdecreed that life begins at “conception,” the Church wasepigenetic along with the Aristotelians [see Maienschein 2003].

Study finds caffeine poisoning on the rise

I suppose it's no surprise that the highly caffeinated soft drink market should cause a spike in the number of cases of apparent caffeine poisoning. Is this part of the report right, though?:

Caffeine toxicity can mimic amphetamine poisoning, cause seizures, psychosis, cardiac arrhythmias and rarely even death, but the most common symptoms reported include irregular heart rate, tremors, stomach upsets and dizziness.

Well, Google knows everything, and links me to this blog post, containing the following extract from a toxicologist's book:

“Caffeine-induced psychosis, whether it be delirium, manic depression, schizophrenia, or merely an anxiety syndrome, in most cases will be hard to differentiate from organic or non-organic psychoses….
The treatment for caffeine-induced psychosis is to withhold further caffeine.”

In fact, the entire website ("The Caffeine Web") describes itself as having the following purpose:

At CaffeineWeb.com, psychiatrists, allergists and toxicologists address caffeine's potential to induce symptoms of mental illness in healthy people.

But it appears to have been a short lived affair. Maybe the author had a relapse after a particularly hard night on the Starbucks.

The lucky tilt

2012-01-15T09:48:00.001+10:00

Here's an interesting story from Physorg about the possible importance of planetary tilt for the emergence of life:

But take away the Earth's axial slant, and the place might become a lot less inviting.

With an obliquity of less than five degrees or so, an Earth-like planet's broader equatorial regions bear the full brunt of a sun's radiance. The polar regions also receive far less sunlight than they do with seasonal ebbs and flows. The result: extreme temperature gradients based on latitude. "Your equator is heated enormously while the poles freeze," said Heller.

In theory, bands of habitability in temperate, mid-latitude zones could persist. In a worst-case scenario, however, the entire atmosphere of a zero-obliquity planet could collapse, Heller said. Gases might evaporate into space around the planet's blazing middle and freeze to the ground in the bleak north and south.

Life, had it ever emerged, would be stopped dead in its tracks.

And the problem is, for life on other planets, that red dwarf stars may well erase planetary tilt relatively quickly.

It sounds like it may be an important reason as to why you can have billions of planets, but not many suitable for life.

Back to Pelagius?

2012-01-14T23:48:00.000+10:00

I saw a link to an article in The Tablet about evolution and religion by Jack Mahoney, but it was behind the paywall and couldn't get to it. (The Tablet offers very little for free.)

Anyway, a bit of Googling shows that Jack Mahoney is a Jesuit and has recently published a book "Christianity in Evolution: An Exploration".

It sounds very interesting. As the review in The Independent notes:

Mainstream Christianity long ago dropped overt hostility to Darwin, and even manages to speak of him fondly on occasion, but it has held back from the next logical step, bringing theology and evolution into meaningful dialogue. Christianity, Mahoney argues, "has been strangely silent about the doctrine of evolution" because to accept it wholeheartedly would then involve a redrawing of the theological map. Yet that is precisely what he wants it to do.

It's true: there's an unresolved tension in the modern Catholic Church between the scientific understanding of evolution and the traditional understanding of the role of Christ; it is being ignored rather than dealt with adequately. The fundamental problem is that evolution erodes the concept of Original Sin. It certainly can't be understood in the previous sense of being the reason why death and suffering came to the Earth.

Thus, it is not surprising that Mahoney follows the path previously trod by another Jesuit interested in evolution, Teilhard de Chardin, in throwing doubt on the traditional understanding of Original Sin. Of course, once you start questioning one traditional theological understanding, it can have a bit of a domino effect. From another review from a Jesuit website:

Mahoney suggests that more traditional understandings of Original Sin, the Fall, Atonement, Justification and similar concepts no longer sit comfortably in an evolutionary context. His own position on sin in this context is very helpful: ‘Sin emerges as humanity’s yielding to evolutionary selfishness and declining to accept the invitation to self-transcendence: it is a refusal to transcend oneself in the interests of others.’ (p.43) Put like that, it makes sense of Paul VI’s claim that ‘the world is sick’ (Populorum Progressio, §66) and his diagnosis of its sickness as ‘the lack of brotherhood among individuals and peoples’. I also liked Mahoney’s comment: ‘What people in today’s culture need most is not the recovery of a sense of sin but the acquiring of a sense of purpose in their lives.’ (p.66)

I don't know: I kind of miss the emphasis on personal sin in the Church these days. But anyway, the review also notes:

He carries this approach to the Incarnation through to offer an interpretation of Christ’s death and resurrection, too, suggesting that evolutionary theology:

proposes that the motive for the Word becoming flesh was not to save humanity from any inherited congenital sinfulness; it was for Christ to lead and conduct the human species through the common evolutionary fate of individual extinction to a new level of living with God. Nor was this done by the offering of Christ as an expiatory sacrifice to placate an injured God; it was achieved by Christ’s freely confronting death and winning through to a new phase of existence to be imparted to his fellow humans in their evolutionary destiny to share fully in the life of God. (pp.14-15)

Such suggestions will, one would think, not endear Mahoney to Pope Benedict; but then again, some people took the latter's mention of Teilhard de Chardin with brief approval in 2009 as indicating a softening of the previous Vatican warnings against his theological thoughts.

The problem, of course, is that Original Sin in its traditional form has been solidly maintained by the Church virtually since its inception. Pelagius' views on the topic (that Adam merely set a bad example to humanity), which presumably can be more easily accommodated within modern understanding of evolution, lost out in the ideological battle with St Augustine. (I see from Wikipedia that there was also Semipelangianism, which was an attempt to find a compromise between Augustinian and Pelagian views, but it was also promptly condemned as heresy.)

I would expect that Pelagianism gets covered in Mahoney's book, as it certainly seems he is effectively arguing that the modern understanding of evolution forces us to return to something resembling it.

Finally, while Googling around on the topic, I found this chapter of an online book * which deals with the theological response in the Catholic Church to evolution. It is very detailed, but rather good. Amongst other points if makes, it seems that it may have been well into the 20 th century before a majority of theologians really started believing that evolution was completely true. This does not surprise me. My own father, for example, never fully accepted evolution, and as it was a topic that the Church chose not to preach about, I expect many Catholics born in the first (say) third of the last century found evolution a topic easy to ignore, and a little hard to believe, and as such it did not represent much of a challenge their faith.

* the website it is from is said to be "Where Christian mysticism, theology and metaphysics meet Eastern religions, Jungian psychology and a new sense of the earth", and appears to be mostly the work of James Arraj, a psychologist who died a year or two ago. I don't know about the quality of everything he has written, but the chapter I have linked to here seems pretty good.

Terry Eagleton dissents

2012-01-14T21:06:00.002+10:00

Religion for Atheists by Alain de Botton - review | Books | The Guardian

Terry Eagleton is always an interesting commentator, even if his Marxist take on Christianity is not for everyone. Here, he reviews Alain de Botton's book that argues in the tradition of Matthew Arnold, who (explains Eagleton):

....feared the spread of godlessness among the Victorian working class. It could be countered, he thought, with a poeticised form of a Christianity in which he himself had long ceased to believe.

The key criticism of this approach is in these paragraphs:

There is something deeply disingenuous about this whole tradition. "I don't believe myself, but it is politically prudent that you should" is the slogan of thinkers supposedly devoted to the integrity of the intellect. If the Almighty goes out of the window, how are social order and moral self-discipline to be maintained? It took the barefaced audacity of Friedrich Nietzsche to point out that if God was dead, then so was Man – or at least the conception of humanity favoured by the guardians of social order. The problem was not so much that God had inconveniently expired; it was that men and women were cravenly pretending that he was still alive, and thus refusing to revolutionise their idea of themselves.

God may be dead, but Alain de Botton's Religion for Atheists is a sign that the tradition from Voltaire to Arnold lives on. The book assumes that religious beliefs are a lot of nonsense, but that they remain indispensible to civilised existence. One wonders how this impeccably liberal author would react to being told that free speech and civil rights were all bunkum, but that they had their social uses and so shouldn't be knocked. Perhaps he might have the faintest sense of being patronised. De Botton claims that one can be an atheist while still finding religion "sporadically useful, interesting and consoling", which makes it sound rather like knocking up a bookcase when you are feeling a bit low. Since Christianity requires one, if need be, to lay down one's life for a stranger, he must have a strange idea of consolation. Like many an atheist, his theology is rather conservative and old-fashioned.

De Botton does not want people literally to believe, but he remains a latter-day Matthew Arnold, as his high Victorian language makes plain. Religion "teaches us to be polite, to honour one another, to be faithful and sober", as well as instructing us in "the charms of community". It all sounds tediously neat and civilised. This is not quite the gospel of a preacher who was tortured and executed for speaking up for justice, and who warned his comrades that if they followed his example they would meet with the same fate. In De Botton's well-manicured hands, this bloody business becomes a soothing form of spiritual therapy, able to "promote morality (and) engender a spirit of community". It is really a version of the Big Society.

Totally drug-resistant TB emerges in India : Nature News & Comment

You don't hear too much about TB as an international disease these days, hence I didn't know this:

Tuberculosis trails behind only HIV as the world’s leading cause of death from infectious disease. But in spite of its impact on human health and economic growth, it has not ranked among the pharmaceutical industry's priorities.

“The pharmaceutical industry had scant interest in TB for decades,” says Richard Chaisson, director of the Center for TB Research at the Johns Hopkins School of Public Health in Baltimore, Maryland. “The industry pretty much concluded it wasn’t an attractive market, there was not enough potential profit.”

The article goes on to say that there has been an increase in development of TB drugs in the last 10 years or so, and none too soon, by the sounds:

Physicians in India have identified a form of incurable tuberculosis there, raising further concerns over increasing drug resistance to the disease¹. Although reports call this latest form a “new entity”, researchers suggest that it is instead another development in a long-standing problem.

The discovery makes India the third country in which a completely drug-resistant form of the disease has emerged, following cases documented in Italy in 2007² and Iran in 2009³.

A minor rat tale

2012-01-13T08:24:00.002+10:00

Watching War Horse the other night, which I thought generally created a very realistic look to trench warfare in World War I, there was one quick shot in which there were a quite a few rats out in the middle of a trench while the last soldier was waiting there after all of his comrades had gone up over the wall and into battle. Hmm, I thought, I know there were a lot of rats around the trenches, but did they really make such a sudden large scale appearance in bright daylight as soon as everyone had left?

Then, this morning, in full sunlight, while idly staring out of the kitchen window, I noticed a rat boldly eating the left over bird seed sitting on the spa cover where we normally put the seed trays.

Time for some rat warfare action again at my house.

Comedy, science and religion

2012-01-12T09:39:00.002+10:00

Today's reading:

* the New York Times magazine has a long article on Stephen Colbert, and focusing more on his recent complicated toying with the Presidential race. All pretty interesting. Unfortunately, Comedy Central now blocks his website videos here, and his show is not shown on any free network, leaving him only accessible to those who get the Comedy Channel on cable TV. This is a terrible outcome, as we recently gave up Foxtel at our house, to no discernible loss of quality of life except for my not being to watch Colbert Report.

* the Christian Science Monitor reports on Nicholas Steno, with the headline "The saint who undermined creationism". Well, he's not quite a saint yet, but I don't recall reading about him before. (He is apparently credited as the first to work out - in the 17th century - that different geological layers are laid down over time and contain a record of life in the very distant past.) He went on to become a bishop. As the article notes, the Catholic church has other clerics who have made big scientific contributions:

Steno was by no means the only Catholic cleric whose observations created models that counter literal Biblical accounts of creation. Gregor Mendel, an Augustinian friar, developed a model of inheritance that made Darwin's theory of evolution intelligible. In the 20th century, it was a Belgian priest, Georges Lemaître, who first proposed the Big Bang theory.

Oddly enough, there is also the case of Lazzaro Spallanzani, who amongst other things:

...discovered and described animal (mammal) reproduction, showing that it requires both semen and an ovum. He was the first to perform in vitro fertilization, with frogs, and an artificial insemination, using a dog. Spallanzani showed that some animals, especially newts, can regenerate some parts of their body if injured or surgically removed.

Given the Church's current teaching, with its overly detailed theologising about the one and only legitimate place for semen to ever be, it's a tad ironic that it was one of their priests who was making discoveries about it.

The man who started the sexual revolution | TLS

Here's an interesting review of a new book about all round loon Wilhelm Reich, whose core idea of the e-vil of sexual repression made him quite popular with middle aged Western men for much, much longer than he deserved.

In Australia, the aging Jim Cairns made it clear that he was very enamoured of Reich's theories, and on checking this I see that it was his she's-not-my-mistress mistress Junie Morosi who was largely responsible for introducing him to the books.

Fear of Horse conquered

2012-01-11T07:48:00.003+10:00

I am happy to report that my not-so-happy Spielbergian experience with Tintin was not repeated with last night's viewing of War Horse.

It's a very impressive movie, and all the good reviews referring to it being in a grand, "classic" Hollywood style of movie making which petered out sometime in the 1960's are right. I agree wholeheartedly with Stephanie Zacharek's comment the other day in Slate:

I love the pure movieness of War Horse—I don’t see it as corny or overcooked.

It is, even by Spielberg standards, an exceptionally lush and beautiful film, and I don't recall a World War I movie which has ever evoked the look of the period in such an authentic feeling way. The John Williams score is not over-powering, the actors are all fine, and the script works well too.

But the largest praise must go to Spielberg himself. The film does not (unlike Tintin) contain motifs repeated from his earlier work in any calculated way; it references classic directors' works but (for the most part) with the added benefit of the graceful camera movement and careful regard to the composition of every single shot that is the hallmark of an extraordinary natural talent.

You should see it at a cinema.

Big battery news

2012-01-09T23:38:00.000+10:00

Two potentially important battery development stories:

* Air battery to let electric cars outlast gas guzzlers

IBM claims to have solved a fundamental problem that may lead to the creation of a battery with an 800-kilometre (500-mile) range - letting EVs potentially compete with most petrol engines for the first time.

Would be very impressive if this pans out - but it is IBM making the claim, apparently.

* new technology that sounds as if it would allow large scale battery storage of solar power:

Battery developer Eos Energy Storage claims to have solved key problems holding back a battery technology that could revolutionize grid energy storage. If the company is right, its zinc-air batteries will be able to store energy for half the cost of additional generation from natural gas—the method currently used to meet peak power demands.

This is a start up making the claims though, so caution is warranted.

The Anti Tattoo League

2012-01-08T22:50:00.000+10:00

I am getting tired of waiting for fashion sense to turn against tattoos, particularly on women.

Call me sexist, but young men generally are known to be silly risk takers in all aspects of life. Ask the insurance companies; and I noted last year the "accident hump" for young men, which apparently "exists in almost all societies and is statistically well documented."

So, it doesn't surprise me that garish and godawful tattoos which will fade into horrible splotchly things in 30 years time appear to be a good idea to some relatively young men. Of course, this doesn't help explain why any man over 25 gets a tattoo, but who am I to disagree with a few decades of American sitcoms which sociologically prove that women are actually, unknown to their oblivious husbands, the most sensible ones in 9 out of 10 marriages.

So, women: come on, you mature earlier and are supposed to be the moderating influence on stupid young men. Hence, I am getting increasingly disturbed at the amount of awful, large tattoos appearing on women's arms. There is no sense of the tattoo craze petering out for females at all yet - in fact, at this rate, I expect to see our Prime Minister return from summer holidays with a "Timbo 4 eva" tatt, complete with a facsimile of her beau armed with haircutting scissors and dryer emblazoned on the large expanse of skin she often shows between her chin and bustline. (See here, here, and especially here.)   My previous cautious hope that tattooing has peaked seems to have been misplaced.

I've said before that the small tattoo on the back of the neck (which seems popular with women) is a bit silly: they're never going to see it themselves, so it's just self branding for the audience that's behind them in the shopping centre. But at least it could always be hidden in future if they tire of it by virtue of longer hair. As for smallish tattoos on the breast line or ankle: again, depends what they wear, but it's not always going to be on display if it turns ugly in future.

But lately I have been noticing absolutely horrendously large tattooing down arms on otherwise conservatively dressed and coiffed women, who don't particularly seem to be wanting to make a "look at me" statement to the world - except, that is (by way of recent example) for the ghoulish zombie like face that is on the forearm handing me change at the newsagent.   Or the shift manager (for goodness sake) at the MacDonalds I was at today, whose entire left arm was devoted to an extensive fairy world themed tattoo. Granted, it was better than the newsagent's tatt, but you look at this otherwise attractive enough young-ish woman in short sleeves and all you can see is an enormous, arm-devouring fairy tattoo.

I think it's time society (or at least, the over 50, wanting-to-control-the-rest-of-society-for-their-own-good part of society to which I subscribe) to start taking matters into our own hands.   I mean, would nice women with tatts in a public environment really punch out people for making the quiet observation "my God, that's a hideous tattoo", or "I would notice your nice face if it wasn't for the fact that you seem to want people to stare only at your arm", or the more vindictive take "tattoos are generally kitsch art*; yours particularly so. I hope you regret it now, or will in the future"? Maybe all of them could then be followed up with a quick "Nothing personal, mind you. I hate the tatt, not the person, but nonetheless seek to encourage a severe reduction in tattooing by whatever guerilla tactic I can muster."

I mean, I seriously want to say those things to men too (well, not the bit about the nice face) but I'm not completely insane. And let's face it: women can have substantial influence on men, but it ain't going to happen with tattoos while ever they are in a competition for garish arm covering ones too.

So the tactic is identified, and all we need now is to apply it. Join the league. I won't do it alone...

* Oddly enough, I Googled "kitsch" to check the spelling, which led me to the Wikipedia entry on the topic which notes the important contributions of both Kant and Hegel to the philosophy of aesthetics; two philosophers who I have recently been discussing at this very blog in other contexts. I was obviously destined to make this post.

UPDATE: whaddya know: Kant did discuss tattoos briefly, and did not approve.

2012-01-08T21:33:00.002+10:00

I don't normally find myself reading the (Brisbane) Sunday Mail, but I had time to kill while my daughter and her friend were in the cinema watching the latest Alvin and the Chipmunks travesty (well, after no.2, I think we can safely assume the latest was dire for anyone over the age of 12) and found myself reading this story about the Walter Mitty style Facebook life of a sometime Brisbane school teacher.

Apparently, people enjoy reading Facebook pages of people they don't know and get upset when they realise there is not a shred of truth in them. According to the report, this guy named an imaginary girlfriend (well, at least the life story was imaginary) who was said to be a drugs squad police officer who had been shot during a raid last November, made a recovery, only to die unexpectedly of a heart attack at the end of December. An imaginary funeral was then announced and took place, and our fiction writing "hero" made the following entry on Facebook:

"One thing that Kell said to me the day before she passed away will always stay with me: 'You have made me the happiest woman in the world . . . I love you Clintypoo . . . I'll always be with you'," Mr Acworth wrote on his Facebook page last week.

People kept reading his Facebook after that? Really?

Was this all an in joke, or maybe a deliberate lesson to his students about the dangers of trusting strangers on Facebook? As far as I can tell from the odd comment I hear, Facebook has had nothing but a malign effect on high school student relationships. (I heard someone on talk back radio in the last year or two complaining that half of each Monday at a high school he/she was involved with was taken up with having to deal with the the fall out from the weekend's vindictive slagging off and bullying on Facebook.)

I remain quietly confident that Facebook has been a net detriment to the betterment of society.

Bryan Appleyard seems inclined to feel the same way, and a couple of days ago he was discussing "twittercide", the phenomena by which a politician or celebrity makes ridiculously unguarded, career-endangering comments on Twitter. Bryan seems to fear the worse:

I suspect there’s a neuroscientific aspect to all this. The neurological walls that divide public from private utterance are crumbling. Our brains are being hollowed out. At this rate there will be no unexpressed thoughts and all the sustaining complexity of the human world will drain away to be replaced by a featureless, babbling simplicity. But you’ll now have to buy my book to find out what I mean.

But to get back to Facebook, I am curious as to whether the possibly apocryphal story at the end of this comment to Appleyard's post is true:

Yes I’m shocked at some of what I see on my 17yr old nephew’s Facebook page but the shock is because I’m 40 and not used to seeing that sort of thing set out so publicly, not in the content itself (which, largely, is the same as anyone’s teenage years). This habit of documenting everything is becoming the norm so if he applies for a job in 15 years then all the other candidates – not to mention the hiring manager, HR department etc. – will be in a similar position. They may be apocryphal but I’ve heard stories about shops & supermarkets actively discriminating against applicants without Facebook profiles etc. on the grounds that it’s an indicator of a normal, hopefully gregarious teenager. In other words the absence of social media history may, in time, become more problematic than its presence.

God help us if this right.

As noted by the Weather Channel's Twitter account, the high temperature of 61°F in Minot, N.D., — an all-time January record — was the average high temperature in April, according to The Weather Channel.

Biologists Yuriy Kirichok and Polina Lishko of the University of California, San Francisco, have made a name for themselves recording the electrical currents that course through, yes, sperm cells....

In a pivotal study, the husband-and-wife team has uncovered how progesterone - a hormone involved in menstruation and embryo development - switches on a sperm's internal electricity. The electric current kicks sperm tails into overdrive, powering the final push toward the egg. Sperm that fail to heed progesterone's "get-up-and-go" signal could help explain some couples' struggles to conceive, say Kirichok and Lishko, both Ukrainian immigrants.

Humans and algae

I've found that American Scientist seems to put a fair few of its feature articles on its website. Here are a couple of some interest:

* the potential for algae based biofuel is discussed in some detail here.
* the question of whether homo sapiens' "modern" behaviours evolved over tens of thousands of years is discussed in this article.

I should add this magazine to the blogroll soon.

Mochi deaths noted - 2012

2012-01-02T19:52:00.001+10:00

It's time for me to note the annual New Year's mochi death toll from Japan.

(Look, this blog is high on Google search for only a few things: Julia Gillard's enormous earlobes, forehead mites, and mochi deaths. I have to keep going to maintain my pathetic numbers...)

Anyway, as with last year, it seems the English language media from Japan is slow to report this now, and I have to resort to Google searching in Japanese.

So far, I've come up with this, courtesy of Google translate, from Yomiuri Online:

The number of people were transported by ambulance to the New Year mochi choking is 3:00 pm daily, up to 13 people in Tokyo alone, two of whom died.

According to the Tokyo Fire Department, around noon on December 28, men in Nerima (82), died 草餅 clog. Noon to 30 men Hino (101) died of suffocation by clogging clots lunch.

I have had this confirmed: yes, the story says the two who died were 82 and 101! (I wonder who fed mochi - famous for causing choking in the aged) to the 101 year old.

And looking that the searches in Japanese, that is all I can confirm so far.

This job is getting harder by the year....

I'll check for more reports tomorrow.

Update: collected figures for the nation remain as evasive as ever. Ah well. Japan has had enough death within the last year without worrying about this.

Still Kant-ing after all these years

2012-01-02T10:30:00.002+10:00

I mentioned before that I had picked up a copy of Philosophy Now for some holiday reading, mainly because Ï felt I just had to reward whoever it was that came up with the cover featuring this: "Kant & Co. Kant, Hegel, Nietzsche, Schopenhauer - Four Dudes that Shook the World".

As it turns out, I didn't find the story on Kant all that good, although it did point out that the famous problem of what his system of morality means for lying (he thought you shouldn't even lie to an axe murderer who arrives at your door looking for your occupant) is about a conflict of values, and Kant didn't talk about this at all.

The relevant section from the article is this:

Staying with the axe murderer, it should be plain that more than one imperative/moral principle is relevant to the situation. Certainly we should tell the truth; but do we not also have an obligation to fight evil? We are confronted with a conflict of values here. Unfortunately, as far as I know, there is no explicit discussion of this issue in Kant. One could assume, however, that his general approach of distinguishing the lesser from the greater evil should be applied. I think Kant might say that although lying is never right, it might be the lesser evil in some cases.

What the writer (Prof Peter Rickman, a former head of philosophy at City University in London) is that the murderer example came up during Kant's life and he did try to address in an essay. If this summary from Wikipedia is any guide, Rickman's optimism about Kant coming up with a "lesser of two evils"resolution seems ill placed:

This challenge occurred while Kant was still alive, and his response was the essay On a Supposed Right to Tell Lies from Benevolent Motives (sometimes translated On a Supposed Right to Lie because of Philanthropic Concerns). In this reply, Kant agreed with Constant's inference, that from Kant's premises one must infer a moral duty not to lie to a murderer.

Kant denied that such an inference indicates any weakness in his premises: not lying to the murderer is required because moral actions do not derive their worth from the expected consequences. He claimed that because lying to the murderer would treat him as a mere means to another end, the lie denies the rationality of another person, and therefore denies the possibility of there being free rational action at all. This lie results in a contradiction in conceivability and therefore the lie is in conflict with duty.

I also note that in what can be argued is a sign that philosophy is either:

a. a lively, relevant and engaging activity relevant to the modern world; or
b. stuck in endless and unproductive repetition and should be replaced with more drinking

you can Google the topic "Kant and conflict of categorical imperatives" and get 225,000 links, including to this one, from a discussion in 2011 which is pretty good.The modern issue of lying to the axe murderer at the door is usually reformulated to the more historically relevant "what should good Europeans have done if they were hiding Jews in their house and a Nazi came to the door asking awkward questions". The "best" answer to the question in that last link notes that strict Kantian thought would deny there really was a conflict; the lying can never be justified. It also points out that Kant would argue that the truthful house owner would not be morally responsible for the deaths of the Jews, which is technically true but no doubt hardly a source of comfort to most people.But the other interesting point is that Neo Kantians have another way out of the specifically Nazi based example:

It's also worth considering that a neo-Kantian would take issue with your example on technical level, arguing that it's not a good example because the Holocaust is an exceptional situation, a special case, if you will.More specifically, the German state at the time formed an illegitimate government, and the SS officers were acting as agents of this illegitimate government, this state that is on face unjust. Given such case, one could argue, his entire corpus of ethics does not apply, as it was only intended to apply to situations involving a just government. (For more on this, see Kant's "Doctrine of Right" and Metaphysics of Morals 6:264, etc.)

That's not helpful if a real revenge seeking violent person comes to your door looking for your relative, however.The last link also provides a link to a philosophy journal discussion of the issue from Nov 2010, which looks interesting indeed, but is behind a paywall. Here's what we can see, from the part of the abstract that is available:

Sorry about the fuzzy quality of the image: I did my best.

The author of the article is Helga Varden, an assistant professor of philosophy at the University of Illinois, and her list of work indicates she's quite the Kant fan. I see she has one paper entitled "A Kantian Conception of Rightful Sexual Relations," which sounds like a blast from a man who thought masturbation was more degrading than committing suicide.

Anyhow, it's interesting to note how Kantian philosophy continues to intrigue and be debated after all these years. The motivation, I suppose, comes down to wanting to ground morality and ethics on something rational other than utilitarianism, which has its own distinct problems (which, incidentally, get discussed in an article in the same issue of Philosophy Now about the "trolley problem".)

Back to normal programming soon...

A short history of drinking on New Year's

2012-01-02T09:20:00.000+10:00

Why we get wasted on New Year's

Salon has a fun look at why drinking and New Year's go hand in hand. Here's a key paragraph:

Across ancient Europe, the yuletide holidays were a free-for-all, made dicey by role reversals: The poor invaded the homes of the rich, men dressed as women, and the lord bowed to the peasant. The 12 days of Christmas, from Dec. 25 to Jan. 7, were set in the mold of the Roman holiday Saturnalia: The holidays were a period of truce, when old grudges should be forgotten (at least temporarily), and anger swallowed. But despite all this brotherly love, the Christmas season had a sinister playfulness, similar to the original concept of trick-or-treating. Echoing Saturnalia’s public ridicule of society’s laws and customs, rowdy bands of peasants invaded the manor, demanding food and drink. In exchange, the lord received his subjects’ blessings and goodwill for the coming year.

It's unfortunate that we can only manage fun for about 8 or 9 days, in this modern world. However, if you had money, you probably would tire of "wassailing"pretty quickly:

By the 17th century wassailing was a holiday tradition. Girls gussied up in holiday finery would carry a dubious alcoholic punch (usually spiced beer with apples) from door to door. The wealthy were expected to drink a toast and offer the wassailers payment in return. Far from the beatific carolers of today, the mobs were known to get unruly: Wassailers would prank or menace householders who refused them booze or money.

After noting that Puritans did not approve of this festive season, we at least can be thankful that we do not have to watch our national leaders emulate the Sumerians:

Mather no doubt was equally horrified by New Year’s Eve, which always marked an apex of drunken revelry. This is true around the world and throughout time: Although the New Year is celebrated from June to January and from Tallahassee to Timbuktu, almost all cultures have used the passing of one year to the next as an excuse to really party. Take for instance the fine old Sumerian tradition wherein the king had public sex with the high priestess of Ishtar, symbolizing the conception of Ninkasi, the goddess of beer.

Hegel and Hegel's God - The Philosopher's Zone - ABC Radio National (Australian Broadcasting Corporation)

I read an article in Philosophy Now by Robert Wallace about Hegel's idea of God, and found it pretty interesting. He was in Australia last year and did an interview with Alan Saunders on the Philosopher's Zone, and it covers the same material.

I found it rather interesting, but you must read it all.

It was time to make another school holiday visit to the Gallery of Modern Art today. It's hard to dislike modern art when it's in such a nice building. Some highlights included a exhibit by a Japanese avant garde artist who's infatuated with dots (I think I had heard of her before), and some Aboriginal dogs from North Queensland. I'll just post the photos to give you an idea:

If ever you are in Brisbane, you must visit it.

Here comes the AP1000

2011-12-31T11:07:00.001+10:00

New Toshiba reactor model gets U.S. nod | The Japan Times Online

I meant to post about this before Christmas, but forgot:

The U.S. Nuclear Regulatory Commission has approved Toshiba Corp.'s AP1000 reactor design, paving the way for the first new reactor construction license to be issued in more than 30 years.

The five-member agency voted unanimously Thursday in favor of certifying the reactor's design.Southern Co. and Scana Corp. are seeking permission to use the next-generation reactors to expand nuclear power output at existing sites in Georgia and South Carolina. The certification "marks an important milestone toward constructing the first U.S. nuclear reactors in three decades," Energy Secretary Steven Chu said Thursday in a statement.

Well, they certainly take their time with new reactor approvals. As the report goes on to note:

The biggest difference between the AP1000 and existing reactors is its safety systems, including a massive water tank on top of its cylindrical concrete-and-steel shielding building. In case of an accident, water would flow down and cool the steel container that holds critical parts of the reactor — including its hot, radioactive nuclear fuel.
An NRC taskforce examining the Fukushima nuclear crisis said licensing for the AP1000 should go forward because it would be better equipped to deal with a prolonged loss of power — the problem that doomed the Fukushima No. 1 plant.

Good to see better passive safety being considered so important in new designs, but I would assume you could better than having a water tank on top.

Anyway, you can have a detailed look at the design at the reactor's own Westinghouse/Toshiba website. It's full of reassuring statements like this:

The AP1000^® pressurized water reactor works on the simple concept that, in the event of a design-basis accident (such as a coolant pipe break), the plant is designed to achieve and maintain safe shutdown condition without any operator action and without the need for ac power or pumps. Instead of relying on active components such as diesel generators and pumps, the AP1000 relies on the natural forces of gravity, natural circulation and compressed gases to keep the core and containment from overheating. However, many active components are included in the AP1000, but are designated as non safety-related.

Multiple levels of defense for accident mitigation are provided, resulting in extremely low core-damage probabilities while minimizing occurrences of containment flooding, pressurization and heat-up.

The AP1000 meets the U.S. NRC deterministic-safety and probabilistic-risk criteria with large margins. Results of the Probabilistic Risk Assessment (PRA) show a very low core damage frequency (CDF) that is 1/100 of the CDF of currently operating plants and 1/20 of the maximum CDF deemed acceptable for new, advanced reactor designs.

I hope they are right.

From The Guardian

2011-12-30T09:42:00.001+10:00

The Guardian may have helped caused the closure of the News of the World by reporting some policeman's wrong theory about how voicemails came to be deleted from a murder victim's phone, and been in bed with Julian Assange until it decided he really was only in it for himself and filed for a divorce, but I still find it one of the best newspaper websites around. Take these items from its Comment is Free section, for example:

* Stephen Kelly, a freelance journalist who still seems to like really big glasses, writes about the deification of Dr Who, which did become a key feature of the show under Russell T Davies, and continues under Steven Moffat. He writes:

The Doctor, of course, isn't marketed outright as a messianic figure but it's all there: "the lonely god", more of an idea than a man, who resurrects himself in a crucifix position; who has, literally, defeated the devil, resisted temptation and forgiven his greatest enemy; "he's like fire and ice and rage", it was once said. "He's like the night and the storm in the heart of the sun. He's ancient and forever. He burns at the centre of time and can see the turn of the universe. And … he's wonderful."

Even the main premise of the show is built upon the concept of existential salvation: the idea that one day this wonderful being will drop out of the sky to rescue us from the crippling tedium of adult life, to make us believe that there is more to existence than work, bills and over-thinking popular tea-time television shows.

All quite true, but it has really started to weigh the show down.

* Denis Alexander (a British biologist and Christian) has a short but pretty good attempt at reconciling Genesis with evolution and atonement through Christ. Here's the key passage:

The tradition of interpreting the early chapters of Genesis figuratively – as a theological essay, not as science – goes back to two great thinkers from Alexandria: the first-century Jewish philosopher Philo, and the third-century church father Origen. In 248 Origen wrote that Genesis references to Adam are "not so much of one particular individual as of the whole human race". Figurative understandings of the Genesis text have been part of mainstream theology ever since.

The first mention of Adam in the Bible is clearly referring to humankind (Genesis 1:26-27) and the definite article in front of Adam in chapters 2 and 3 – "the man" – suggests a representative man, because in Hebrew the definite article is not used for personal names, with Eve being the representative woman.

The Genesis narrative tells the story of humankind going their way rather than God's way. On the day that Adam and Eve sin, they do not drop dead but proceed to have a big family, albeit now alienated from friendship with God, causing spiritual death. Nowhere does the Bible teach that physical death originates with the sin of Adam, nor that sin is inherited from Adam, as Augustine maintained. But the New Testament does teach that humankind stays true to type – all people sin by their own free will – and Christ dies for the sins of all. Christ is the second Adam who opens up the way back to friendship with God through his sacrifice for sin on the cross. The result is the "at-one-ment" that the first Adam – Everyman – is unable to accomplish by his own efforts.

I'm not sure I'm entirely convinced, but it seems this is a summary of an argument he puts in an entire book on the subject, and it may be worth the effort.

* On a lighter note, kind of, a writer looks at the latest report of Japanese retreat from relationships, and brought to my attention this story from earlier in the year:

Virtual girlfriends became a sensation last summer, when Japanese game-maker Konami released its second-generation of its popular Love Plus, called, aptly, Love Plus +, for the Nintendo DS gaming system. Konami skillfully arranged for an otherwise deadbeat beach resort town called Atami to host a Love Plus + holiday weekend. Players were invited to tote their virtual girlfriends, via the gaming console, to the actual resort town to cavort for a weekend in romantic bliss. The promotion was absurdly successful, with local resort operators reporting that it was their best weekend in decades.

He ends on this point:

"Maybe we're just advanced human beings," says a Japanese friend of mine over dinner this week in Tokyo, who won't let me use her real name. She is an attractive, 40-something editor at one of Japan's premier fashion magazines, and she is still single. "Maybe," she adds, "we've learned how to service ourselves."

Seriously, if research leads to more advanced ways for men to derive more, ahem, pleasure from virtual interactions with their electronic girlfriends, Japan is over with faster than even currently anticipated.

The comments following the article, from (I assume) mainly English people complaining about the difficulties in relationships indicate that the Japanese may just be a bit ahead of the curve.

* Finally, the marvellously named Morven Crumlish talks about the Scottish celebration of Hogmanay (the New Year party which is, apparently, pretty full on in the drinking and fighting.

Interestingly, I see that they share the Japanese idea of cleaning up the house for the New Year.

But in comments, there are many people of Scottish heritage who say they are over the whole thing. I liked this one:

Once you get out into the rural areas hogmanay is more community based with first-footing and the meeting up with friends. But in the big cities it has lost its main meaning. The Edinburgh hogmanay parties are just ugly vulgar spectacles packed out with interlopers and freaks, whereas in the west of Scotland the neds and radge use it has an excuse to act out the Battle of Helms Deep from the Lord of the Rings using tonic wine bottles has props. If memory serves the A&E departments in the West of Scotland at hogmanay and new years days are swamped with an insane amount of stab victims in the 18-24 demographic.

For once i think Glasgow council done the right thing this year by stopping the paid celebrations in George Square. theres a lot of people who are on the poverty line and cant afford a big swanky doo at Hogmanay. If anything the first-footing tradition of the lump of coal and mini bottle of grouse carries more symbolism than any amount of drunk hussies on Princes street.

Call me ignorant, but I can't say I've heard of "first-footing" before, so here we go:

"First footing" (that is, the "first foot" in the house after midnight) is still common in Scotland. To ensure good luck for the house, the first foot should be male, dark (believed to be a throwback to the Viking days when blond strangers arriving on your doorstep meant trouble) and should bring symbolic coal, shortbread, salt, black bun and whisky. These days, however, whisky and perhaps shortbread are the only items still prevalent (and available).

The website I got that from goes on to explain some ever odder old Scottish New Year's traditions:

The traditional New Year ceremony of yesteryear would involve people dressing up in the hides of cattle and running around the village being hit by sticks. The festivities would also include the lighting of bonfires, rolling blazing tar barrels down the hill and tossing torches. Animal hide was also wrapped around sticks and ignited which produced a smoke that was believed to be very effective to ward off evil spirits. The smoking stick was also known as a Hogmanay.

Some of these customs do continue, especially in the small, older communities in the Highlands and Islands of Scotland where tradition, along with language and dialect are kept alive and well. On the Isle of Lewis, in the Outer Hebrides, the young boys form themselves into opposing bands, the leader of each wears a sheep skin, while a member carries a sack. The bands move through the village from house to house reciting a Gaelic rhyme. On being invited inside, the leader walks clockwise around the fire, while everyone hits the skin with sticks. The boys would be given some bannocks - fruit buns - for their sack before moving on to the next house.

OK. I think we've all learnt something today. Unless, of course, you are smarter and better read than me.

Chlorine and spirits - a ramble around Spring Hill

2011-12-28T23:47:00.000+10:00

As it looked as if a storm might be on the way this afternoon, and the normal Council pools are not good places to be when lightning is around, I took the kids to the Spring Hill Baths in Brisbane today.

I hadn't been there for nearly 30 years, I reckon. Built in 1886 and (seemingly) not changed much since, it's a good little bit of history tucked away in the inner Brisbane suburb which I have always liked. Here's a photo of the interior, with the changing booths lined around the perimeter. You can't see the "women only this side" and "men must not loiter at the end of the pool" warning signs, but they are there:

That photo, incidentally, is courtesy of a rather distinctive looking fashion blog, presumably run by a Brisbane woman. Not my cup of tea, but worth a quick look.

Now that I look at other, older photos, I see that it has changed quite a bit inside:

The photo is from 1910, and one suspects that life preservers were necessary at pools at the time due to women being pulled under by the weight of their wet bathing suits.

More about the history of the pool is found at the Queensland Heritage website, and I see it did have a very practical aspect:

Constructed for the Corporation of Brisbane in 1886 at a cost of £2,526, the Spring Hill Municipal Baths provided the city with its first inground public baths. They replaced in popularity the older floating baths in the Brisbane River, and provided an important hygiene/sanitation facility in Spring Hill....

On the evening of 9 December 1886 and amid great ceremony, the baths were opened by the Mayor of Brisbane, James Hipwood, who took the first plunge.

One of the principal reasons for establishing the Torrington (Arthur) Street bath was its location above the Spring Hollow (Water Street) drain, installed in 1884, the waste water from the baths providing a daily cleanse. River water from Petrie's Bight was pumped to a small reservoir at the top end of Albert Street, then gravity fed down Spring Hill to the Hollow, where it was stored in holding tanks (now boarded over) at the far end of the baths. Each evening the pool was drained and every morning the water was replenished in a process lasting several hours. This system of flushing the Spring Hill drain was employed for three-quarters of a century.Not until 1914 did the city council install a salt water supply scheme to which the baths were linked. As the Brisbane River grew more polluted, chemicals were added to the pool water, and finally a filtration system was installed in 1961.

Interestingly, when you look at the history of swimming pools at Wikipedia, it seems pools only really started being built in England around the late 1830's, with swimming clubs taking off about 30 years later. Brisbane was relatively quick to get into the act.

The pool was also socially advanced: the Queensland Heritage article I linked to before notes that in 1927 it was one of the first pools in Australia to allow mixed bathing.

Given the age of the pool, it did get me thinking about when they might have started chlorinating it. As you can see from the above extract about its history, the answer is not readily available; but then again, when did any pools start getting chlorinated? The answer has not been so easy to find.

According to a brief article from America (which, incidentally, notes that the first American swimming pool was built in 1887 - a year after the Spring Hill Baths opened):

....the first attempt to sterilize a pool in the UnitedStates usingchlorine was at Brown University in 1910. The 70,000-gallon Colgate Hoyt Pool was chlorinated by graduatestudent JohnWymond Miller Bunker.

But it doesn't then go on to explain when it started being used more widely. It does note, though, that:

Priorto theintroduction of sterilization technologies most swimming pools werefiltered tokeep them somewhat clean and the water was changed frequently.

Given that the Spring Hill Baths were used as a daily iant flush of the Spring Hollow drain, this is obviously the way it was kept partially clean.

Oh, here we go: I've found the full length article on the history of chlorination in pools that my earlier link only summarised: it would appear that in the US, chlorination was introduced commercially in the 1920's, and by 1930, most high school pools used chlorine in one form or another.

So there's another small gap in my knowledge filled.

Anyway, after the swim and an ice cream, I took the kids down the road to the Spring Hill Spiritual Church. Why would I do that? Well, because (as mentioned at this very blog in 2006, but you probably weren't paying close attention), Sir Arthur Conan Doyle visited it in 1921. I was hoping that the plaque recording this was on the outside of the Church, but it doesn't seem to be. Oh well.

I can't find any photo of his visit either. The best I can come up with of his trip to Brisbane is a photo of him visiting a Goodna bee farm. The John Oxley Library blog entry on the visit notes that not only was Brisbane pretty fast at building a bathing pool, it had some surprisingly early enthusiasts for spiritualism too:

In closing Conan Doyle observed that he’d been told he could expect only “one person” at his Brisbane lectures. In fact the city had a strong core of devotees and one of Conan Doyle’s special honours during his visit was to lay the foundation stone for the Brisbane Spiritualist Church. Already in the early 1880s a weekly magazine The Australian Spiritualist was being published in Brisbane and there were practitioners like the daughters of German-born musician Professor A. Seal who recorded musical scripts transmitted to them by their father from the grave.

This reminds me: I think it was on a tour of the Noosa River many years ago, that I heard there was a historic house on it which was famous for its owners being heavily into spiritualism.

Oh. It would appear to be on the island that Richard Branson built his mini resort. Maybe it's haunted.

So, that's it for now. I was going to mention my long time admiration of the Queensland Transport building at Spring Hill, but that will have to wait for another day.

We have drift off: Balloons to the edge of space - New Scientist

New Scientist looks at a Spanish company that is actively developing civilian flights in helium balloons that would take the joyriders 34 km high before descending in on a guided parachute:

There is no doubt that it is possible, because it has been done many times before. In the 1950s and 1960s, more than a dozen crewed balloons journeyed to near-space. In 1957, for instance, Joe Kittinger of the US air force ascended to a height of 29 kilometres in a capsule attached to a helium balloon. He enjoyed the ride so much that when ordered to descend, he replied: "Come and get me."

Zero2Infinity hopes to spread that joy to the civilian population. The company has carried out several test flights of uncrewed balloons, and earlier this year got the funding needed to carry out its first flight carrying people.

The plan is to use a massive helium "bloon", as the company likes to call it, to carry a pressurised capsule with space for two pilots and two passengers up to 34 kilometres above the Earth. You can book now - but at €110,000 per ticket, you'll need a little spare cash.

Sure sounds like a safer option than Virgin's joyrides, which I predict is a business that will go defunct as soon as a fatality occurs.

The New Scientist article also points out that one study indicates that the Virgin rocket (which has particularly dirty exhaust) could have very adverse effects indeed:

All rockets inject pollutants directly into the stratosphere, which has various effects. In particular, hydrocarbon-fuelled rockets, such as the kerosene-powered Soyuz, produce a lot of soot, which warms the planet by absorbing the sun's heat. While soot in the lower atmosphere usually rains out after days, it can remain in the stratosphere for a decade or more, massively amplifying its effect. In 2010, Martin Ross and his colleagues at The Aerospace Corporation, a non-profit institution based in El Segundo, California, modelled the effect of 1000 sub-orbital launches each year with a rubber-burning engine like that of Virgin Galactic's SpaceShipTwo. The study concluded that the climatic effect of this kind of space tourism could be on a par with that of all commercial aeroplane flights put together.

Why hasn't this very anti-Green aspects of Richard Branson's vanity project ever had more publicity?

Evolution of Angels: From Disembodied Minds to Winged Guardians

I see National Geographic had a story about angels for this Christmas, but it's a pretty quick overview that concentrates on Christian ideas of angels. This part reminded me of CS Lewis' Screwtape Letters:

Of course not all angels are angelic, according to some Christian traditions. Satan himself, it's been said, was once an angel named Lucifer.
The fact that angels can fall from grace is an important point, Catholic University's Root said—it implies that they have free will.
"You even had some theologians in the medieval and the early modern periods who thought that there was an adversarial angel, a fallen angel, assigned to each person as well as a guardian angel—though this was never an official thought," Root said.

The next part is also a bit novel to me:

As early as the second and third centuries, Christian scholars such as Origen of Alexandria saw important roles for fallen angels, Notre Dame's Cavadini said.
"For Origen and a lot of church fathers, angels participated in the governance of the universe at God's will," Cavadini said.
"That also meant that the fallen angels were intended to participate in the betterment of the universe, and that you have to take them very seriously, because they still did participate—but in a negative way."

Jewish ideas of angels don't get a mention, but I see Wikipedia gives a brief outline.

Some holiday reading in The Economist

2011-12-27T18:32:00.001+10:00

Two articles from The Economist are worth a look:

* a look at the "invention" of modern science fiction by Hugo Gernsback and his serialised novel Ralph 124C 41+ which appeared 100 years ago. I have heard of Gernsback before, but not his clunky novel. (Its title puts me in mind of Lucas' THX 1138.)

* a somewhat amusing article on euphemisms around the world. As some people not in comments, the writer doesn't quite get American practice in this regard exactly right, but I hope his other examples are valid. Some highlights:

Some Chinese euphemisms also stem from squeamishness. Rather than inquire about a patient’s sex life, doctors may ask if you have much time for fang shi (room business). Online sites sell qingqu yongpin, literally “interesting love products”.

But Chinese circumlocution is often a form of polite opacity. Chinese people don’t like being too direct in turning down invitations or (as many journalists find) requests for interviews. So they will frequently reply that something is bu fangbian (not convenient). This does not mean reapply in a few weeks’ time. It means they don’t want to do it, ever. If they don’t want to tell you what is going on they will say vaguely they are bu qingchu: literally “I’m not clear.”...

A prostitute accosting a client on the streets of Cairo will ask Fi hadd bitaghsal hudoumak ? (Literally, “Do you have someone to wash your clothes?”)

Even the most straight-talking obfuscate that line of work. Swedes, like many others, refer to världens äldsta yrke (the world’s oldest profession). A brothel in Russian is a publichny dom—literally a “public house”, which causes problems when British visitors with rudimentary Russian try to explain the delights of their village hostelry. In China many hair salons, massage parlours and karaoke bars double as brothels. Hence anmo (massage), falang (hair salon) or a zuyu zhongxin (foot-massage parlour) can lead to knowing nods and winks. For obscure reasons, Germans call the same institution a Puff. In Japan, such places are called sopurando, (a corrupted version of “soapland”) or a pin-saro (pink salon).

Christmas Day, with a modest proposal

2011-12-27T17:53:00.001+10:00

Well, after my last grumpy sounding post, I feel I should point out that Christmas Day itself was very pleasant. We had 4 relatives over, which just made for a comfortable sized Christmas lunch, which I also thought notable this year for its relative economy.

On the menu: 2 Coles cooked chickens cut up and served cold ($10 each); some rare sliced roast beef also served cold (my wife bought and cooked it, but she tells me it was only $10); a kilo of Crystal Bay prawns bought from Aldi (of all places) for $20 (this was the real economy triumph of the day, given that the fish shop near Aldi was selling prawns for an extraordinary $47 this year - I have no idea why they were so expensive); a green salad made with a bag of salad leaves from Coles (about $3) some grape tomatoes (about $2.50) and some half a packet of feta cheese (price unknown); some home made potato salad that I would estimate as costing barely $6; another salad involving chinese cabbage and noodles (not sure, but probably around $7); some bread rolls from Woolworths; and that was about it for the main meal. (OK, allow some cost for the cocktail sauce, mustard for the beef, etc.)

My sister brought a trifle for desert, another sister made some vanilla slices and an ice cream type desert, and my wife had made a Christmas cake for the first time and it was very successful. There were some lychees (quite cheap this year - under $10 a kilo) and cherries too. Someone brought chocolates and nuts so they were floating around in a basket too.

Add the sparking wine, the most expensive of which was French but only $13, with the follow up being Australian sparkling under $10, and you have what I think as a remarkably good but economical cold Christmas lunch which was more than enough plenty for 6 adults and two children. (In fact, we are finishing the last meat leftovers today.) Of course, the other reason I enjoyed Christmas lunch so much this year could be because I didn't have to watch my drinking because of an upcoming drive home, for once.

The other fantastic thing about Christmas this year was having it on a Sunday, so that Christmas Eve was not a mad rush of trying to finish work earlier so as to get to the shops before they shut for last minute items of food or gifts. It seemed to me that even the supermarkets were better prepared than other years, with heaps of food still available on Christmas Eve.

I propose a modest change to the calendar, such that December 25 becomes a floating date which must fall on the nearest Sunday. So, for example, what would have been Sunday 22 December becomes 25 December, and the next Wednesday becomes the 22 nd.

Somehow, I can imagine computer programmers having a problem with this, but if they could handleY2K with nary a plane falling out of the sky, this should be a snip.

UPDATE: Gosh, this is a bit of serendipity: my suggestion is not as insane as first thought. Physorg notes that a scientist and an economist have come up with an idea for a "perpetual calendar" that is the same every year, with this key feature:

"Our plan offers a stable calendar that is absolutely identical from year to year and which allows the permanent, rational planning of annual activities, from school to work holidays," says Henry, who is also director of the Maryland Space Grant Consortium. "Think about how much time and effort are expended each year in redesigning the calendar of every single organization in the world and it becomes obvious that our calendar would make life much simpler and would have noteworthy benefits."

Among the practical advantages would be the convenience afforded by birthdays and holidays (as well as work holidays) falling on the same day of the week every year. But the economic benefits are even more profound, according to Hanke, an expert in international economics, including monetary policy.

Now this would be useless unless 25 December is a Sunday, but have a look at this graphic of the Hawke-Henry Permanent Calendar - and yes it is!!

The only problem with it - instead of a extra day added in leap years, you need leap weeks every 5 or 6 years. Well, that seems to change the suggested simplicity of the system somewhat, doesn't it? Maybe those weeks can just be international holidays.

The only problem with this proposal, which, by the way, almost sounds like an Aprils Fool's joke come early, is that it has got publicity at the Cato Institute. There's a rule of thumb that's good at the moment that if a libertarian thinks it's a good idea, it probably isn't; either that or it's wildly impractical, so it is probably the best sign that this is a silly idea.

Actually, now that I read that Cato article, the far sillier idea they have is that the world operate on Universal Time, and they suggest that in a country like Russia, the banks open at the exact same time so they can all work with each other, even though that would mean some banks permanently opening at the crack of dawn. I'm not entirely sure they are serious...

Anyway, if it means Christmas Day is permanently a Sunday, I suggest a political party be instituted to get calendar reform going.

Boxing Day viewing report

2011-12-27T10:38:00.002+10:00

I invited the kids to join me in watching Tintin in 3D yesterday. (Actually, my son had been waiting for months to see it; my daughter was not so keen, but I refused to take her to the third Chipmunks movie after the dire experience of the second one.)

The big cinema was nearly full, and the audience seemed in a very good mood. They cheered when the 3D filter was belatedly put on a few minutes after the "please put on your 3D glasses" slide had appeared. (This delay happened last time I was at Southbank Cinema a couple of weeks ago when we saw Puss in Boots.) And they seemed to enjoy the movie, as indicated by a smattering of applause at the end.

But me? Sad to report, I was pretty underwhelmed.

On the first issue of whether it demonstrated that motion capture has overcome the "uncanny valley": well, yes, more or less. But the odd consequence of this is that, if you then use it for characters are "cartoony" in appearance such as the Thompson twins, it becomes rather the equivalent of using real actors with ridiculously obvious prosthetic noses, etc. The eyes look pretty real: the rest of the face doesn't.

The other problem in motion capture is still to do with physics. There is scene in the trailer you may have seen where the Thompson twins are running down the street and one hits a lamp post and recoils backwards. You can tell exactly how this was done with a wire on the actor from the mere look of the physics. Motion capture, it seems to me, is an unhappy attempted mix of the freewheeling visuals of cartooning but with a continual and unavoidable connection to the physics of the real world that acts as a restraint on what it can do. I mean, I was more impressed with the imaginative action in The Incredibles than with anything I have seen in motion capture.

I also have a problem with getting any sense of danger in this technique. I haven't really worked out why this should be so - perhaps it is simply an inability to stop being aware of how it was made - but I feel more capable of feeling completely animated characters as being in danger than I do with motion capture ones. There is one scene in particular in Tintin which is meant to evoke an Indian Jones style of encroaching danger to the hormonally challenged title character; but for me, it just did nothing.

So colour me unconvinced: I am really having trouble envisaging ever liking this way of making films.

I also didn't think the 3-D added much, which surprised me, because I thought Spielberg might have novel ideas for its use. In fact, unless it was just the cinema I was seeing it in, I felt for the first time that it was making the screen darker than it should. This is a problem that some people have noted about the current technology, but perhaps it is because I have only ever seen computer animated films in it that I haven't noticed any issue with the brightness of the image. (Yes, Tintin is animated too, but still, it seemed to be murkier looking that I expected.)

Another issue I had with the film is with the screenplay:   I just didn't think it was so clever.   Some of the exposition (with Tintin working out various connections) just seemed clumsy and capable of being done better. But part of the problem may be with the source material: I have never read the comics in detail but they have always struck me as sort of dull. Sure, they are colourful, and their appeal to many boys is undeniable, but I grew up on Scrooge McDuck adventures in the classic Carl Barks period, and they seem to me to have a more continual element of wit and humour which I couldn't really see happening enough in Tintin.

I wonder if my problem with the screenplay lies with the involvement of Steven Moffat. Last night, the family watched the Dr Who Christmas Special written by him, and I thought it was awful.

I usually enjoy these specials - even last year's with the flying shark pulling a sleigh had a kind of inspired madness, I thought.

But last night's was just terrible in nearly every respect, except for the fact that Matt Smith does fine with the role. I mean, the very first few minutes were a warning sign, with the Doctor shown to have an ability to survive and shout for minutes in the vacuum of space. (There are some breaches of physics in films I am loathe to forgive, even in Dr Who.) I've grown tired of the Moffat returns to the World War II period, the whole "lifeforce" needing to find a strong person to use as a lifeboat, and that being the mother, was just sort of corny and made no real emotional sense to me. I didn't even think the acting by the mother was particularly convincing.

I think the episode is just further evidence that Steven Moffat is burnt out with the show and he needs to leave. (Or even the show needs another break from its current incarnation.)    Oddly enough, many Guardian readers say they did feel moved by the episode. But on that blog, there are some people who seem to share my feeling that the show has lost its way, and Moffat is probably at the heart of the problem.

So, that's a cranky sounding Boxing Day report, isn't it?   It's not all bad: my son did enjoy Tintin (although he seemed pretty cool on the Christmas episode too), and my daughter perhaps liked the movie more than she expected. Even I would say it's not a terrible movie; just a disappointing one with which I disagree with quite a lot of what critics have said about it.

My hope is that War Horse might be better than Tintin, but it's about a horse. What a worry.

We should scour the moon for ancient traces of aliens, say scientists | Science | The Guardian

Paul Davies makes a fun suggestion:

Prof Paul Davies and Robert Wagner at Arizona State University argue that images of the moon and other information collected by scientists for their research should be scoured for signs of alien intervention. The proposal aims to complement other hunts for alien life, such as the Search for Extraterrestrial Intelligence (Seti), which draws on data from radiotelescopes to scour the heavens for messages beamed into space by alien civilisations.
"Although there is only a tiny probability that alien technology would have left traces on the moon in the form of an artefact or surface modification of lunar features, this location has the virtue of being close, and of preserving traces for an immense duration," the scientists write in a paper published online in the journal Acta Astronautica.

The only thing is, they doubt there is much point in using crowd-sourced examination of the photos due to the potential for disagreement over what is or isn't significant. There is also going to be a lot of material to look through:

The scientists focus their attention on Nasa's Lunar Reconnaissance Orbiter (LRO), which has mapped a quarter of the moon's surface in high resolution since mid-2009. Among these images, scientists have already spotted the Apollo landing sites and all of the Nasa and Soviet unmanned probes, some of which were revealed only by their odd-looking shadows.
Nasa has made more than 340,000 LRO images public, but that figure is expected to reach one million by the time the orbiting probe has mapped the whole lunar surface. "From these numbers, it is obvious that a manual search by a small team is hopeless," the scientists write.

Tintin cartoonist Herge: Georges Remi is the subject of two new biographies. - Slate Magazine

The Slate article above gives a very brief outline of Tintin creator Herge's life.

One likes to imagine that making a career out of comics would be good work - doing something you love, in your own studio, that sort of thing.

But it didn't work out that way for Herge, apparently:

As the strain of producing the Tintin strip, as well as other assorted other projects, took its toll on him, Remi suffered an array of psychosomatic symptoms, including outbreaks of eczema and boils, and was plagued by recurring nightmares of whiteness. (Evidently there was nothing more terrifying than a blank page.) Remi seems to have retained an unhealthy distance from his own life, disappearing into his work until the work itself became the problem.

Ah well, being untalented at art has its up side after all.

Interesting.

Mad scientist update

2011-12-23T07:11:00.003+10:00

While everyone is getting slightly worried that scientists have been busy creating killer bird flu, I note on a smaller scale that this photo appears in Nature's slideshow of striking images from 2011:

And the explanation:

Rats don’t deserve their bad name, but this ball of fury won’t win over many murophobes. Russian scientists bred this aggressive rat strain to compare it with more docile creatures in a study on domestication that has teased out several genetic regions linked to tame traits.

Great. All we need now is for them to escape and be capable of carrying killer bird flu, and we've got bio-apocalypse for Christmas.

I can't stop talking about movies this week.

Most nerd excitement is directed at the Hobbit trailer, a movie in which I have no interest whatsoever. At least, I assume, this is the last bit of Tolkien anyone will be putting on screen.

On the other hand, I am kind of interested in Ridley Scott's prequel to Alien, even though it would seem it's a movie very unlikely to have much in the way of a happy ending. It looks as if it may be visually very impressive, though:

Shared tastes

A Christmas movie story: from merriest to muckiest | Sarah Hughes | Film | guardian.co.uk

The Guardian film blog notes the best, and worst, Christmas films, and in the process shows I am not alone in certain tastes.

First, it opens with "You already know to avoid CGI Tom Hanks when selecting a Christmas movie..." referring to The Polar Express. I was half watching it the other night when the kids had it on, and it seems from my blog search that I might have previously overlooked commenting on my puzzlement with that movie.

My big, big issue with it, apart from the waxwork manikin look of the people, is the creepy, empty, sort of rococo Stalinist design of the elf city at the North Pole, complete with massed, brainwashed looking elf-dom in the main square that is so reminiscent of a "dear Leader" rally in North Korea.

Who on earth came up with that art design? Is it copying the book, but done on such a vast scale that it changes into unsettling? It doesn't seem to bother children, I admit, but I just can't over the emotionally cold feeling that this gives the movie.

Anyway, back to the Guardian: I tend to agree with those that I have seen of the "best list", although I have to admit to having never seen It's a Wonderful Life. I don't know how this has happened, but it doesn't seem to be repeated all that often in this country.

In the "worst" category, the problem is that everyone (including me) knows to avoid bad Christmas movies, and most never made much money. But it does start with this view of Richard Curtis:

I toyed with including Love Actually but decided that my near-pathological hatred of Richard Curtis counted as bias

Well, there you go, I am indeed not alone.

In fact, the biggest worry by far about Spielberg's War Horse movie is that Curtis is a co-writer! This movie is getting to be classic example of intensely mixed feelings: Spielberg adapting a successful book and play - but it's about a horse and has Richard Curtis. The old joke about a mother-in-law driving a husband's Mercedes over a cliff has nothing on this.

An Interview With Steven Spielberg - NYTimes.com

I consider it my duty to note interviews with Steven Spielberg, especially when it is another unusual year when there are two of his products out at the same time*. (To be honest, he doesn't say anything all that interesting, though.)

War Horse is getting pretty good reviews, but not universally so. This may be a good sign: some Spielberg films have been over-praised, most notably Saving Private Ryan, and that can lead to a sense of disappointment.

But it will be an achievement if Spielberg can get me to cry at a horse movie. Ugh.

In other movie news: Mission Impossible: Ghost Protocol is great. Brad Bird does turn out to be a good action director, as I had predicted. The movie has a lighter tone than all of the earlier ones, but it works. My wife (and even my son) felt it was a bit tiringly over-frenetic, but I really just found myself wanting to watch it again to note the action more carefully. And I probably will.

* it is reminiscent of the grand year of 1982, when both ET and Poltergeist (OK, he only produced and co-wrote that one, but it was rumoured he may have done a bit of directing on set too) were both at the Forum twin cinema in Albert Street in Brisbane. I told friends that I was going to go there in a robe and with a censer (the incense burning thing in a Catholic church) to give honour to the significance of this event. (I am inordinately fond of Poltergeist as well as ET.) My failing to do so resulted in the cinema closing down and being turned into a very nice Borders store, which now sits empty.

Pope Heads Into Busy Christmas Season Tired, Weak - NYTimes.com

Interesting report in the New York Times that quotes a few close observers who say that Pope Benedict seems to be getting frailer lately. It also notes that he has been open in the past about his view that a Pope should resign if he feels not physically up to the job.

There is not a lot of precedent for such resignations, however, as the article notes the last one happened about 600 years ago.

It would be an interesting thing to happen again; if anything, I think people would acknowledge a resignation as very reasonable and preferable to watching a slow decline.

Unsporting rodent based entertainment

2011-12-15T23:18:00.001+10:00

I was looking around the net for rat related stuff when I stumbled onto this bit of history I hadn’t heard of before: in Victorian England, “rat baiting” in rat pits around the city was a popular form of betting entertainment. Wikipedia notes an account from a participant:

A hundred rats were put in it, large wagers went back and forth on whose dog could kill the most rats within a minute. The dogs worked in exemplary fashion, a grip, a toss and it was all over for the rat. With especially skilful dogs, two dead rats flew through the air at the same time...

The Wikipedia article has lots of illustrates of the set up at these disreputable venues, like this one:

This must have been the toff’s night at the rat pit. Other venues seemed to have looked rather rougher:

Anyway, the last rat pit was close in 1912.

I did not know that this was a Victorian form of entertainment.

Update: Here's a blog post about the last rat pit in New York, shut down in 1870 by the SPCA. I can't see anything about rat pits in Australia on Google, though.

A bunch of old interests

2011-12-15T07:51:00.001+10:00

Well, looking around the net this morning, there are a bunch of stories about some of my long term interests, as previously mentioned on this blog:
1. Methane apocalypse soon? A Russian scientists tells the Independent that he hasn’t seen such large methane plumes in the Arctic Ocean before:

"Earlier we found torch-like structures like this but they were only tens of metres in diameter. This is the first time that we've found continuous, powerful and impressive seeping structures more than 1,000 metres in diameter. It's amazing," Dr Semiletov said.
"I was most impressed by the shear scale and the high density of the plumes. Over a relatively small area we found more than 100, but over a wider area there should be thousands of them," he said….

Another scientist doing the research says:

"Methane released from the Arctic shelf deposits contributes to global increase and the best evidence for that is the higher concentration of atmospheric methane above the Arctic Ocean," she said.
"The concentration of atmospheric methane increased unto three times in the past two centuries from 0.7 parts per million to 1.7ppm, and in the Arctic to 1.9ppm. That's a huge increase, between two and three times, and this has never happened in the history of the planet," she added.

Well, that’s far from encouraging.
Update: both Revkin and James Annan say this was a beat up. I hope so.

2. Small nuclear shows some promise.   Another study indicates that making small, modular nuclear power may be a better way of deploying nuclear quickly, rather than building the expensive mega plants of old.
This is what I suspected on a hunch.   Why aren’t I running the world?
If the world was serious about greenhouse gases, there ought to be a scientific and technological commission either run by the US, or preferably, internationally, to identify the most promising path to rapid deployment of nuclear with systems that have as a primary feature passive safety. But a lot of things have to be considered: sources of uranium and efficiency of uranium use, the type of waste they make and its recycling and disposal, new nuclear designs and how far off testing and certifying they are; ease of export of the technology, etc.   This is the sort of leadership needed: not just leaving it up to the hopeless mishmash of competing ideas around at the moment.
3. Marijuana does hurt the brain.   Some pretty interesting research from Melbourne, in which 12 year olds had brain scans, and then they were re-scanned at 16, after some of them had started using marijuana.
The most surprising thing is that the size of part of the brain at 12 seemed gave an indication as to whether they would try it:

“What we found is that only the OFC predicted later cannabis use, suggesting that this particular part of the frontal lobe increases an adolescent’s vulnerability to cannabis use. However, we also found no differences in brain volume in other parts of the brain that we have shown to be abnormal in long-term heavy cannabis users, confirming for the first time, that cannabis use is neurotoxic to these brain areas in humans.”

The OFC plays a primary role in inhibitory control and reward-based decision making; previous studies of adolescent cannabis users have demonstrated subtle deficits in problem-solving, attention, memory and executive functions.

“In adult cannabis users, decreased activation of the OFC has been associated with faulty decision-making, suggesting that a reduced ability to weigh the pros and costs of one’s actions might render certain individuals more prone to drug problems,” Professor Lubman said.

I guess in a hundred years time, school career counsellors will just be examining scans and assigning kids to jobs.
4. Primordial black hole search. Some scientists are looking at Kepler satellite data to see if they can pick out small, primordial black holes as a possible source of missing dark matter. I kind of hope they don’t find it, as I don’t want the Earth to bump into one.
5. Ocean acidification and the Bering Sea: Skeptical Science looks at ocean acidification and its apparent (or potential) effects in one part of the world. Not good.

Another AGW is bad for fish study

2011-12-14T08:46:00.000+10:00

Expansion of oxygen minimum zones may reduce available habitat for tropical pelagic fishes

The abstract:

Climate model predictions^{1, 2} and observations^{3, 4} reveal regional declines in oceanic dissolved oxygen, which are probably influenced by global warming⁵. Studies indicate ongoing dissolved oxygen depletion and vertical expansion of the oxygen minimum zone (OMZ) in the tropical northeast Atlantic Ocean^{6, 7}. OMZ shoaling may restrict the usable habitat of billfishes and tunas to a narrow surface layer^{8, 9}. We report a decrease in the upper ocean layer exceeding 3.5 ml l⁻¹ dissolved oxygen at a rate of ≤1 m yr⁻¹ in the tropical northeast Atlantic (0–25° N, 12–30° W), amounting to an annual habitat loss of ~5.95×10¹³ m³, or 15% for the period 1960–2010. Habitat compression and associated potential habitat loss was validated using electronic tagging data from 47 blue marlin. This phenomenon increases vulnerability to surface fishing gear for billfishes and tunas^{8, 9}, and may be associated with a 10–50% worldwide decline of pelagic predator diversity¹⁰. Further expansion of the Atlantic OMZ along with overfishing may threaten the sustainability of these valuable pelagic fisheries and marine ecosystems.

Big ideas by Newt

2011-12-14T07:17:00.000+10:00

Apocalypse Newt

So, Newt Gingrich is known for having hi-tec dreams of everything from lunar colonies to space based missile defence to geo-engineering. I remember reading on his (Pournelle's) blog that Jerry Pournelle used to be have some association with him (as an advisor, perhaps) and that would probably explain Gingrich's fondness for all things "space".

In fact, after taking climate change seriously, Gingrich has now flipped to being a skeptic, just as Pournelle always has been. But Jerry Pournelle is getting on (age 78): it seems to be built into the natural psychology of aging males that believing in AGW gets harder and harder for them over the age of 65. How old is Gingrich, by the way? 68, I see. Well, that explains that.

But even Romney is 64: he probably will start genuinely stop believing in AGW next year.

(And just why do Republicans so often go with the old dudes as presidential candidates? OK, so George Bush was an exception, but Reagan, Dole, McCain, Bush Snr?)

Anyway, as a fan of the return to the moon myself, this should make me feel more generous than I do towards Gingrich. But I find the guy hard to like. Seems far too flip floppy on everything (not just climate change), and doesn't really have the right image of a leader, especially against a more youthful Democrat.

Honestly, if the Republicans want to look dynamic, they should chose Huntsman. But he's poison to the doomed idiot wing of the Republicans known as the Tea Party, due to having done terrible things like genuinely believe in AGW (before having to semi-recant for political purposes) and being sophisticated in his knowledge of foreign affairs.

The Republicans are a lost cause, for now.

Update:

This New Yorker article notes that he has written quite a lot in the alternative history genre too.

It also argues that this is what's behind his sudden popularity:

Gingrich’s sudden rise and special appeal to the emotions of “the base,” one suspects, stem less from his vaunted “big ideas” than from his long-cultivated, unparalleled talent for contempt. In 1990, when he was not yet Speaker, he pressed a memo on Republican candidates for office, instructing them to use certain words when talking about the Democratic enemy: “betray,” “bizarre,” “decay,” “anti-flag,” “anti-family,” “pathetic,” “lie,” “cheat,” “radical,” “sick,” “traitors,” and more. His own vocabulary of contempt has grown only more poisonously flowery. President Obama’s actions cannot be understood except as an expression of “Kenyan, anti-colonial behavior.” Liberals constitute a “secular-socialist machine” that is “as great a threat to America as Nazi Germany or the Soviet Union.” There is “a gay and secular fascism in this country that wants to impose its will on the rest of us” and “is prepared to use violence.” In this campaign, Gingrich’s performances in televised debates have been widely deemed effective. But what has won him his most visceral cheers from the audiences in the halls—audiences shaped and coarsened by years of listening to talk radio and watching Fox News—is his sneering attacks on moderators, especially those representing the hated “liberal” media.

In March, at the Cornerstone Church, in San Antonio, Gingrich declared, “I am convinced that, if we do not decisively win the struggle over the nature of America,” his grandchildren will live “in a secular atheist country, potentially one dominated by radical Islamists and with no understanding of what it once meant to be an American.” Last spring, this was a kind of right-wing performance art. Now it is the language of the man leading in the Republican polls, a man who—in the real world, not the alt-world—could, not inconceivably, become President of the United States. Imagine that.

What a country...

How Do You Prove Someone's a Witch in Saudi Arabia? - By Uri Friedman | Foreign Policy

An amazing article about the ongoing prosecution and punishment of witchcraft in Saudi Arabia. Some highlights:

....the Saudi Interior Ministry announced on Monday that it had beheaded a woman named Amina bint Abdul Halim bin Salem Nasser for practicing "witchcraft and sorcery." The London-based al-Hayat newspaper, citing the chief of the religious police who arrested the woman after a report from a female investigator, claims Nasser was tricking people into paying $800 per session to have their illnesses cured.
So, how did Saudi authorities prove Nasser was a witch? The government hasn't gone into detail, but a look at the kingdom's past witchcraft cases suggests the bar for proving someone guilty isn't very high. Witch hunting is fairly institutionalized in Saudi Arabia, with the country's religious police running an Anti-Witchcraft Unit and a sorcery hotline to combat practices like astrology and fortune telling that are considered un-Islamic.

Huh. A country with a sorcery hotline. Just how often do people use this for mere revenge against someone who annoys them? The article does note that foreigners need to be particularly careful:

A Human Rights Watch researcher tells The Media Line that foreigners in particular are often the targets of sorcery accusations because of their traditional practices or, occasionally, because Saudi men facing charges of sexual harassment by domestic workers want to discredit their accusers.
The evidence arrayed against witchcraft suspects typically revolves around statements from accusers and suspicious personal belongings that suggest the supernatural, in a country where superstition is still widespread. In 2006, for example, an Eritrean national was imprisoned and lashed hundreds of times for "charlatanry" after prosecutors argued that his leather-bound personal phone booklet with writings in the Tigrinya alphabet was a "talisman."
A year later, Saudi authorities beheaded an Egyptian pharmacist who had been accused by neighbors of casting spells to separate a man from his wife and placing Korans in mosque bathrooms.

What a great country to avoid.

Chemically scrubbing CO2 from the air too expensive

From the link:

Someday the world may be in a position to lower the concentration of heat-trapping carbon dioxide in the atmosphere by chemically removing it from the air.

But not soon; the process is simply too expensive, say scientists from Stanford and MIT.

A study published in the Proceedings of the National Academy of Sciences, co-authored by Stanford energy and environmental researcher Jennifer Wilcox, concludes that if air-capture of carbon dioxide with chemicals is ever used, it will be far in the future.

For now, it is much more economically efficient to capture the carbon dioxide that enters the atmosphere from the smokestacks of large centralized sources such as power plants, cement plants, fertilizer plants and refineries.

After a detailed comparison, the research team concluded that the cost of removal from air is likely to be on the order of $1,000 per ton of carbon dioxide, compared with $50 to $100 per ton for current power-plant scrubbers.

What do animals 'know'? More than you may think

Rats are getting some unusually good PR lately. Last week, it was studies that indicate empathy for other rats, this week, their thinking seems deeper than we, um, thought:

"Rats often make judgments and behave as if they're rational creatures," said UCLA associate professor of psychology Aaron Blaisdell, a member of UCLA's Brain Research Institute and senior author of a new study published in the December issue of the journal Psychonomic Bulletin and Review.
"To make a decision in the face of uncertainty, rats call on prior history and reasoning," Blaisdell said. "They apply what they know to a situation where they are uncertain. The rats are not necessarily thinking like little humans, but they have learned through experience. A lot of animal behavior seems to be rational. Their behavior follows logical inferences."

You can read about the studies suggesting this at the link.

Acidic oceans threaten fish : Nature News & Comment

I've become slack about posting items concerning ocean acidification. This is partly because a lot of the studies being reported at the Ocean Acidification blog have become very technical in nature - examining in minute detail the biochemistry of marine organisms and trying to tell exactly how ocean chemistry affects it - and also because there doesn't seem to have been much reported lately on the rate of acidification.

But still, I should go back and catch some of the stories that I have missed.

Anyway, today there is a Nature report (see above) about a couple of studies indicating that young larvae of a couple of fish do not do well under acidification.

Skeptics will no doubt have a couple of objections: firstly, some coastal waters where fish breed already have a really high range of natural pH. I doubt that this is a valid objection, as an increase in acidification from the atmosphere just means that the range is going to shift its mean and peaks to the high end, so it still may be a problem. The second issue will be whether natural selection will mean fish will be able to evolve quickly to adapt to the new acidification regime.

Quick adaptation to warmer sea warmers was indicated in a recent Australian study, but whether this will apply to acidification is anyone's guess.

On the downside of the warmer water story, another study recently indicated that fish parasites can do better in warmer water, which just shows how complicated it is trying to work out the net effect of warming oceans and increasing acidification.

Still, it surprises me somewhat that it took this long for a studies on fish larvae mortality under increased acidification took this long to be done.

Big rain

2011-12-11T22:48:00.001+10:00

John Nielsen-Gammon has had a series of posts up about material he has found interesting at the AGU conference last week.

As the the extensive floods in Queensland last year made me consider the impact of floods as a major issue with AGW, I will reproduce Dr J's post from Climate Abyss about possible record heavy rains to come:

Probable maximum precipitation (PMP) is a commonly-used design input value for water projects such as dams for which failure is not an option. It’s estimated, in effect, by assuming that all possible factors contributing to heavy rain (upstart speed, moisture content, duration) come together at the same time and place to produce the flood to end all floods.

Ken Kunkel noted that in a warming climate, one of these is expected to change more than all the others: the moisture content of the air. What about the worst case scenario: the peak moisture content of the air at any given location?Kunkel showed evidence that the peak has indeed increased over time across most of the United States, though there are data quality issues that need to be worked out (historical weather balloon water vapor measurements are pretty dodgy). More importantly, the climate models are consistent in showing increases in the future.

We’re talking about increases of 10% every few decades. This would correspond directly to 10% increases in PMP. And increases much greater than 10% in the cost of new projects. And even greater expenses for retrofitting. That’s unless we decide that we are willing to tolerate a greater risk of man-made catastrophe from dam failure than before.

Dateless in Kyoto

The Japanese government takes its dwindling birth rate seriously enough to conduct surveys on how its people are feeling about relationship. The latest one indicates the population issue is not going to solve itself any time soon:

According to the poll in June this year by the National Institute of Population and Social Security Research, a record high 61.4 percent of unmarried men between 18 and 34 reported having no girlfriend, up 9.2 percentage points since 2005. Unmarried women with no boyfriend in the same age group hit a record 49.5 percent, up 4.8 percentage points. The very idea of having girlfriends and boyfriends seems to be on the way out.

Shopping underground

2011-12-11T22:25:00.001+10:00

Salon, of all websites, has an article about renewed interest in the recreational and commercial use of underground spaces in the US. I like this paragraph:

Historically, developers have spent a lot of time trying to make underground spaces feel like they’re not underground. But the weirdness of an underground park is exactly why we like it. It’s intriguing and strange and a little bit spooky. “The underground can be claustrophobic, but it can also be this cozy, Fantastic Mr. Fox layer of reality,” says Barasch. So, rather than turn underground spaces into sterile retail or prefab food courts, ablaze with primary colors and piped-in pop music, developers could instead embrace the natural state of these spaces — their “undergroundness” — when designing for them. This doesn’t mean making them cheerless, it simply means respecting their subterranean identity, much like the High Line kept in place some of the former railroad’s industrial decay.

Movies to see

2011-12-11T14:46:00.001+10:00

After a year of not too much to get excited about, it's surprising to see that there are at least 3 movies of interest which are about to be released in Australia and are getting strong reviews:

1. early reviews of Mission Impossible: Ghost Protocol are very good, and as I anticipated, Brad Bird has apparently made an excellent live action director. A couple of reviewers are actually calling this the most enjoyable MI movie, so I am keen to see it.

The NYT has an interesting article about Mr Bird in which it's noted that Tom Cruise contacted him after The Incredibles and asked, if ever he wanted to do live action, to direct him. There you go - Tom has good intuition about some things, at least.

2. Tintin starts on Boxing Day, and it's likely my family will be there to see it at the earliest opportunity. The reviews remain mostly strong, and I see it has already made a couple of hundred million dollars in Europe. (It seems particularly popular in France - I am a little surprised at the weakness in the English box office. Maybe some people did pay attention to the relentless and bizarre Guardian obsession against the film?

3. Spielberg's War Horse also gets released on Boxing Day, and although it seems to me to be getting very little in the way of pre-publicity, some preview audiences have been pretty impressed. I am pretty sure I will have to overcome my horse aversion as see it.

Saturday night cooking report

2011-12-11T12:06:00.001+10:00

Why did it take me so many years to get around to cooking a version of paella? I've like the idea of this dish for a long time. I think I have rarely eaten it, but I have always like watching how it's made on cooking shows.

Finally, I was prompted by a Slate article headline I saw this week:

Paella Is a Party! Stop wasting your time with risotto.

So, last night I finally got around to making a relatively straight forward chicken and prawn paella, and it came out pretty good. The recipe was based on one from from taste.com.au (which had many, many versions to try), but I did vary it a bit:

Ingredients (serves 6)

1 tbsp olive oil
6 chicken thigh fillets, halved
12 medium green king prawns, peeled leaving tails intact, deveined
2 chorizo sausages, coarsely chopped
1 brown onion, coarsely chopped
1 red capsicum, seeded, coarsely chopped
2 cups arborio rice
2 garlic cloves, crushed
2 tsp ground smoked paprika
1/2 tsp saffron threads
400g can diced tomatoes
1 litre chicken stock
1 cup water
Fresh continental parsley leaves, to serve

The chicken is cooked in the olive oil first (and set aside), then the prawns (also set aside) and finally the chorizo. Leave the chorizo in and add the onion and capsicum and cook til softened. (Actually, I think next time I would just add the choriso, onion and capsicum at the same time.) Add the rice, garlic, paprika and saffron (personally, I don't think the absence of saffron is going to be noticeable) and stir for a minute, then add the tomato and stock. Leave to cook under low heat for 15 minutes (no stirring is important) Add the chicken gently and let cook for another 10 minutes.

Now, the recipe then calls for the cup of water, add the prawns on top, cover and cook for 5 minutes. This reheats the prawns, but I think you would always have to leave the cover off again to let all the additional water be aborbed/steam off.

I changed the water to half a cup of white wine and water, but even then, I think next time I would try a bit less liquid at this stage.

This receipe is also devoid of green (well, save for the parsley, which I didn't have.) So we added a cup of frozen peas that had been unfrozen in boiling water, and stirred it in at the last minute.

Some recipes note that it is important to let paella rest for 5 or 10 minutes after cooking, and I think there is something to that.

I'm not sure that arborio rice is really the best for this too; next time I would be inclined just to try any old medium grain rice; but don't get me wrong, it tasted pretty good even with arborio.

Anyway, even the kids found it acceptable, and my wife liked it too, although we both agreed a little bit of chilli flake would be nice too if we were cooking it just for ourselves. In any event, it was another happy Saturday night when a new recipe is successful.

Climate change not in retreat

2011-12-05T08:39:00.000+10:00

Three-quarters of climate change is man-made : Nature News & Comment

Interesting new study with some interesting conclusions, using a new method:

Knutti and Huber found that greenhouse gases contributed 0.6–1.1 °C to the warming observed since the mid-twentieth century, with the most statistically likely value being a contribution of about 0.85 °C. Around half of that contribution from greenhouse gases — 0.45 °C — was offset by the cooling effects of aerosols. These directly influence Earth's climate by scattering light; they also have indirect climate effects through their interactions with clouds.
The authors calculated a net warming value of around 0.5 °C since the 1950s, which is very close to the actual temperature rise of 0.55 °C observed over that period. Changes in solar radiation — a hypothesis for global warming proffered by many climate sceptics — contributed no more than around 0.07 °C to the recent warming, the study finds.
To test whether recent warming might just be down to a random swing in Earth’s unstable climate — another theory favoured by sceptics — Knutti and Huber conducted a series of control runs of different climate models without including the effects of the energy-budget parameters. But even if climate variability were three times greater than that estimated by state-of-the-art models, it is extremely unlikely to have produced a warming trend as pronounced as that observed in the real world, they found.

The Kevin problem

2011-12-05T07:55:00.001+10:00

Julia Gillard rallies as Tony Abbott's rating falls, while Kevin Rudd blasts Labor conference | News.com.au

Is it just me, or does News Ltd seem especially keen to talk up "Kevin Rudd is bound to challenge" stories i the last few weeks?

I would assume he was upset at not being mentioned by Gillard at her conference speech, but surely the point is that no commentator seems to think that Rudd has more than a handful of rusted on supporters within the Parliament. Maybe he is also smarting over not being recognized for priming Slipper to take over the speaker role: but then again, he denied he was directly involved in a plot.

Anyhow, I would have thought that most Australians at this time of year were not playing too close attention to the Labor conference, and for those that did, it seems to me that they probably got the impression of Gillard coming out of it pretty well.

Sure, the party now supports gay marriage, but no expects that it will pass on a conscience vote. There - those that want it can now blame the Coalition for not doing a similar thing, as I wouldn't mind betting that the few Labor people who would not vote for it might be matched by the few Coalition that would cross the floor. A conscience vote on this seems to me the right thing to do on a matter that a large section of the community does think relates to a very ancient tradition and matter relating to morality.

Uranium to India was a clear Gillard win, and the endorsement of a disability insurance scheme is a real Labor style reform that might go over with the electorate as very worthwhile.

But what to do about Kevin if he maintains his unhappiness in the new year? I mean, until the pokies reform is bedded down (probably by a compromise of some sort), I can't see Gillard's approval, or Labor's primary vote, climbing too high just yet. So Kevin will still have something to agitate over.

Yet with a hung parliament, he can't afford to resign and have a by-election, even if a plum UN job was beckoning him.

He is, basically, the unsolvable problem, at least for the next 6 to 12 months.
