Around the flood

This is how the week developed since my last post on Wednesday morning. (Feels longer ago than that, but experiencing novel events has that effect.)

There were plenty of warnings on Tuesday evening that the Brisbane flood could be very big – equal to, or even slightly higher, than the 1974 flood. However, since I had been told by long term residents that the group of shops in which my office is located had only taken water up to the car park (which rises about 1 – 2 meters above the street level) in 1974, I wasn’t too anxious. Indeed, the Council flood maps on the internet that evening indicated that the local knowledge was right.

However, on Wednesday morning, Lord Mayor Campbell Newman said on TV that they had revised the maps overnight, and people should check again if their homes or businesses could be affected. And yes, when I checked, the flood line had been moved just enough to indicate that my office/shop area were in danger.

I was not much encouraged when, getting to the office at about 8.15 am, the artificial lake within about 30 metres of my shops (and which had not been there in 1974) had already flooded across the road as far as the eye could see, and this was still 12 – 18 hours before the predicted peak. One house on the far side of the lake already looked to have a couple of meters of water over its ground floor.

It seemed prudent to remove the computers and take them home. This didn’t take too long, but then nearby residents mentioned that the road between me and my home, which I already knew was cut in one direction I could take, was now getting inundated (via the backflowing stormwater drains) in the other direction. If I waited too long I might not be able to get home at all.

I therefore left in a hurry with a lot of things left on the office floor. In any event I had to go pick up my mother from her retirement village, which I had been told was going to be evacuated as a precaution as well.

As I drove away from the office, there was quite a lot of activity in some lakeside houses to get furniture onto vehicles. Further along, I could see water over the road at the top of a side street which I knew led down closer to the lake. Many expensive houses down there would clearly already be inundated, and it was only about 9 am.

The main road just a little further along did indeed have a foot or so of water over it, but only for a short distance. I went and collected my mother, noticing the water was already down the far end of her street.

I got her home, which was already hosting another family (friends of ours with children) who had left their home in another flood prone suburb across the river and stayed with us on Tuesday night.

At about 11.30am, I drove back to see if I could get to the office, but the road was now covered with about 2 – 3 feet of water and the police were there, really only wanting to let residents through. It was not worth the risk.

So by midday I was back home, watching TV and wondering why coverage seemed very centred on inner city suburbs (such as Milton and Rosalie) and then leapt over to Ipswich and Goodna. I did feel slightly indignant that my already well flooded suburban area was not rating much of a mention.

Around 2 pm the power went off and stayed off for about 24 hours. I had telephone calls from friends near the office who said water had started coming up out of the stormwater drains in front of the carpark.

As Australian readers would know, the flood peak overnight on Wednesday was about 1 to 1.5 m less than they had predicated. In fact, I think by Wednesday afternoon, they knew that the river at Ipswich had peaked well under the forecast, so I did relax a little. Still, I was very glad to be able to get to the office on Thursday morning to see that, as in 1974, the flood water stopped in the car park driveway. If the peak had been as forecast, it would have been a very close call as to whether water would have entered the building.

The number of houses around my area which were flooded has surprised me, particularly around the lake, and in another area around a golf course. I’m not sure when they started selling lakeside land, and it may well have been before the Council restricted building homes on levels below the 1974 flood. But certainly, this would have been the first time since then that they faced a major flood, and I expect that many were surprised that the lake was capable of such a rise. There are certain other streets in the suburbs near mine which I am sure would only contain houses built since 1980, yet have dozens of houses flooded. I am sure there will be some questioning of the Council flood level advisory maps after this.

On Thursday afternoon, when the water had already dropped by a meter or so, I was able to get around a bit and take some photos. The quality may not be great, but clicking might make them a bit bigger:

Street 1 resized

One of the main local roads; houses down the street on both sides had plenty of water through them.

Street 2 resized

The road along my Mum’s retirement village. I was told houses down the far end had at least a meter of water through them. (You can also see the "high water"mud mark nearly half way up on the row of bushes on the left.) The retirement village was spared, again with water just reaching the car park entrance.

View towards boat ramp resized

On the left, well under the water, is the entrance to a boat ramp, playground and picnic area, none of which (including the roof of the toilet block, on the higher part of picnic area) could be seen. I think that’s the rear wheels of a car floating upside down near one of the light poles.

Next, my inner anti-sporting grump was not too shocked to see the Little Athletics club house and grounds, which I have been a reluctant attendee with my daughter on Friday nights last term, has had a make over:

Now for the best big flood scenes near me:

Shopping centre & highway sharpen

Shops flood

And for last, the difference a day makes in a flood. Here’s a photo from roughly the same position late this afternoon:

Shops 14 Jan resized

I know the flood effects for me was nothing compared to all those who did have homes and businesses under water, and who may remain without power for days yet. Still, one brush with a flood this size is enough to satisfy any curiosity about what it’s like to be near a natural disaster.

Floods

Brisbane's floods will not directly affect my house, but certainly I live and work in suburbs which will have houses inundated. (There would seem to be a chance my office may be cut off, although it did not quite go under in 1974.)

This has been a strange disaster. For those who have seen the footage of the Toowoomba flash flood: this is not a town, sitting as it does on top of a range, that is known for such flooding.

As for the Lockyer Valley disaster - yes, people know it has creek and river flooding, but again, nothing like what has been seen on TV yesterday. It is amazing to think that the death toll may climb into the dozens.

The rain has stopped since yesterday afternoon, which is one thing at least. But it does feel odd, knowing that a large volume of water is still headed to the city. At least people will probably start to feel easier that the Wivenhoe dam will not be breached. At 190% capacity (for a dam built to go to 225%), some people were definitely wondering about that yesterday.

There will be many people who cannot work today. I may be distracted for a little while.

Steve's stupid but brilliant idea of the day

Brisbane and much of Queensland has been incredibly wet this summer, with thousands of homes flooded, and hundreds of thousands of parents with school children depressed that the kids have inside continuously for the last 4 weeks.

Now we get news that:
The Australian Building Codes Board is preparing the first technical standards for construction in areas liable to flooding.
Excellent. My plans for all flood prone houses to be Queenslander style built on pontoons may get a run yet.

Child-like drawings to come, as well as a photo of the really weird slug found on a tree yesterday at Mt Glorious during a break in the torrential rain. Yes, my wife was that desperate to get out of the house.

Update: here's the slug. (Easily 6 - 8 cm long):


As for the floods generally: amazing and pretty horrifying scenes of flash flooding in Toowoomba was on the news tonight. Two people were killed in a car swept away (I assume, not one of the cars in this video). Here's an amateur video from the town:



I see that Lord Mayor Campbell Newman is saying that it is only the Wivenhoe Dam, which is full and letting go of a lot of water, that is preventing Brisbane from having the equivalent of a 1974 flood. There is actually some talk now of it being the biggest floods Queensland has ever seen, but exactly how you compare these things I'm not sure.

Make friends and influence people the Anglican way

There was a short story in the Courier Mail this morning about how the Anglican Church in Brisbane is looking for more, younger recruits to the priesthood. Apparently there is a shortage. I thought, last I heard, that they actually had quite a lot of women priests to spread around their increasingly dwindling congregation, but maybe not.

Anyway, the main point of the post is to note that this comment:

Executive director of Brisbane's ministry education commission, Reverend Steven Ogden, said the priesthood was desperately in need of educated men and women.

"We need university students with sharp minds, not the stereotypical, eccentric weirdos," he said.

I can only assume Rev Steve must have missed the sensitivity training day at theological college (or whatever it is Anglican clergy in training attend.)

UPDATE: I should have noted that the other possible explanation (in fact, probably the most likely one) would be an out of context quote by the Courier Mail. See comment below.

New York Times finally gets ESP

The NYT website, at least, is featuring prominently the story of soon to be published ESP experiments of Daryl Bem.

You read about them at this very blog back in October. It takes a while for international journalism to catch up with me.

One small aspect of the experiments is a little amusing:

A software program randomly posted a picture behind one curtain or the other — but only after the participant made a choice. Still, the participants beat chance, by 53 percent to 50 percent, at least when the photos being posted were erotic ones. They did not do better than chance on negative or neutral photos.

“What I showed was that unselected subjects could sense the erotic photos,” Dr. Bem said, “but my guess is that if you use more talented people, who are better at this, they could find any of the photos.”

Every politician should have one

Romania is planning on taxing its witches, according to The Guardian. But they are fighting back:
Queen witch Bratara Buzea said she will lead a chorus of witches in casting a spell using a concoction of cat excrement and a dead dog.
Interestingly, the report goes on to note:
Such spiritualism has long been tolerated by the Orthodox Church in Romania. The late Communist dictator Nicolae Ceausescu and his wife, Elena, had their own personal witch.
Well, at last I understand the best role for this woman in the Australian parliament.

From the "only in Saudi Arabia" files

In the Gulf News:

Riyadh: A squad from the Department for the Promotion of Virtue and Prevention of Vice has raided the house of a Saudi man following a tip off that he is practising sorcery.

It was reported that the suspect has bewitched a girl and married her without the knowledge of her family.

Following investigation, the suspect was put in jail, awaiting trial. Saudi Arabia applies capital punishment for sorcery.

The incident, which took place in Riyadh, came to light when a security guard, working for a private company, accused a fellow citizen of bewitching his daughter and his other family members and used magic to marry the girl without a marriage contract.

And the report ends:
The Department for the Promotion of Virtue and Prevention of Vice [gosh, that's an appealing name for a a government department, isn't it?] said it is conducting awareness programmes against the practice of withcraft.
Now there's a lecture that would be interesting to see.

The other funny thing is that, in the same edition of Gulf News, we can also read:
Saudi Arabia confirmed on Tuesday it plans to buy more F-15 fighter jets as part of a massive arms deal which the US State Department said in September could be worth up to $60 billion.
This is a tad odd, isn't it? If the government believes in sorcery enough to be giving public education programs and killing people for it, why do they need 20th century jet fighter technology to protect themselves? Can't they train up a crack elite squad of good sorcerers who will, I don't know, stand at the border and make the enemy forget that Saudi Arabia is there?

Now, although it's no fun to be fair when poking fun at Saudi Arabia, I suppose I should acknowledge that England was prosecuting Helen Duncan under the Witchcraft Act in 1944. However, as Wikipedia explains, this for the offence of fraudulently claiming to be procuring spirits. Still, it would appear that you could say England officially believed in witches until that act was repealed in 1951.

So, maybe I'm being unfair about Saudi paranoia. Let's see: what else is there in Gulf News today?:
Saudi nationals have seized a vulture wearing a Tel Aviv University tag and a transmitter, prompting speculations that it was used by Mossad, the Israeli spying agency, to gather intelligence on the area....

The vulture was handed over to the Saudi security.

According to Israeli media, the tags indicated that the six-year-old bird was part of a long-term research project into migration patterns.
No, clearly this is just a country that has been left out in the hot sun for too long.

The bugs, they’re all over me!

Those who are inclined towards itchy self consciousness after reading about the amazing variety of life to be found living on and in our bodies should probably not read The top 10 life-forms living on Lady Gaga (and you).

I thought I had heard of most kinds of bugs that live in and on us before, but the article still contained a few surprises (or things I had forgotten about.) For example:

Inside your lungs is a kind of fungi called Pneumocystis. It cannot live outside of human lungs. No one has been able to grow it anywhere else.

And (emphasis mine):

I will wager that Lady Gaga’s head is crawling with mites. They live in her pores and come out to have sex under the shade of her wig while she is on stage. Well, not just then. They do it other times too. She could have more than one kind of mite. Forehead mites (Demodex spp.) have not been well studied and they are so small that differences among species might be impossible to detect simply by studying how they and their parts look under the microscope (which is all that has been done). Where these mites have been studied, they have mostly just been counted. They are more common on older people than on younger people. The exception to this pattern is among the Tokelau islanders where the pattern is the reverse (more mites on younger people) for reasons unknown. On average--the Tokelau Islanders in the audience notwithstanding--more than half of us have forehead mites and quite a few of us host two species. Some of us may even host as of yet unnamed species. Every so often these mites are badly behaved (they are linked to rosacea, although innocent until more convincingly proven guilty), but mostly they seem to have no effect on our lives. Maybe they are even good for us? Who knows? What is clear is that they bury themselves in our pores and eat.

Update: you can read more about face mites here.

Actually, I did recall reading before about a particular mite that lives in the base of eyelashes, and it turns out they are the same thing. I was just a bit confused by them being called "forehead mites". Wikipedia notes:
It is quite easy to look for one's own Demodex mites, by carefully removing an eyelash or eyebrow hair and placing it under a microscope.
Umm, not sure I want to know, when they look like this:


As for their possible role in rosacea, it's interesting to note this (from a couple of links back):
Over the years, considerable evidence has accumulated that Demodex folliculorum may at least play a role in certain skin conditions, particularly papulopustular rosacea. Patients with immunity problems, such as AIDS patients, appear to be particularly susceptible. Symptomatic infestation with demodex mites is called demodicidosis or demodex folliculitis.

While the role of demodex in disease is still unclear, treatment for skin problems in cases where there are many mites present now often includes a topical antiparasitic cream. Treatment successes where the mites were targeted provide further indirect evidence that face mites cause skin problems, at least in some instances.
Excuse me while I go practice how long I can hold my breath while keeping my head in a bucket of rubbing alcohol.

Assange compared

There's a very good article in the Australian today contrasting Assange and "Wikileaks" to the leak of the Pentagon Papers, showing that those who think that Julian can justify his actions by comparing it to the former leak are badly mistaken.

Even so, it notes that the biggest effect of Wikileaks so far has been to actually make America look better than many thought:

...ironically, the leaks show that the US government is not an "authoritarian conspiracy" at all. They show, notably in the case of relations with the Arab states of the Middle East, an American government served by generally candid diplomats, trying to keep its balance and think its ways through a devilishly challenging set of problems, chief among them how to dissuade the theocratic and dangerously anti-Semitic regime in Iran from developing nuclear weapons. They show nuance and scruple, not authoritarian conspiracy. They show honest assessments of world leaders such as the corrupt and domineering former KGB thug Vladimir Putin, or the corrupt and irresponsible Italian leader Silvio Berlusconi. Moreover, as Robert Gates, heir to McNamara, has pointed out, the leaks were possible precisely because the US government had been trying to circulate more information to more of its civil servants in order to facilitate learning. That was Ellsberg's agenda. Assange wants to prevent just such learning.

Climate change this and that

Michael Tobis (and Gareth Renowden) have really been ripping into some recent bogus claims by climate “skeptics”lately. First, it was the non story of the New Zealand temperature record adjustments, somehow claimed by the skeptic group that forced a reassessment as some sort of triumph over the e-vil lying NIWA scientists. Yet, gullible skeptics lap this sort of stuff up.

Secondly, it was a takedown of a Watts Up With That post by Don Easterbrook, in which a puzzling graph was claimed to show something it patently did not. Again, about 95% of the comments following the story at Anthony Watts place brought this hook, line and sinker.

There really is a new definition for gullible, and it’s Climate Change Skeptic.

As someone commented at Tobis’ blog, it seemed clear that Watts Up With That has in the last couple of weeks been running with a pre-emptive campaign to argue why the possible hottest year on record title for 2010 (it will be a close call with 1998) is not really so important anyway. I reckon this sort of pre-emptive action was obvious in 2010 too, with respect to Arctic ice loss when it wasn’t clear just how wrong Steven Goddard’s prediction would be.

At other blogs:

* Barry Brook has an important post on the meaning of the “no statistically significant warming since 1995” line. In fact, he puts up a persuasive argument as to why it was (in effect) the wrong question that was being asked in the first place.

* Tamino looks at the GISS temperature record to once again emphasise via graph that there is no last decade decline in the warming trend, which is the key thing (not the annual ups and downs.)

* Stoat had a pretty good take before Christmas on the issue of explanations for the current (and previous year’s) cold European winter, which can be summed up as:

So before explaining such-and-such an event, the first thing you need to do is to show that there is something in need of an explanation. A cold December in Europe doesn't fall into that category.

He doesn't deny that the ideas being run as to why these winters have been so cold might be correct (see the Real Climate post on this), but he considers it safer to not try to over-explain weather and its relationship to climate change. Given the way skeptics smack their lips over decade old statements that snow was well and truly on the way out in Britain, he has a pretty good point.

* It’s easy to forget, in light of the well publicised extreme heat of Russia in 2010, that Japan also suffered a record hot, long summer last year. As I noted in my first post of 2011 earlier today, it seems that the record number of deaths for the elderly has been blamed on this. The Japan Meteorological Agency seems right on board with AGW, and it is fascinating how so many agencies from so many countries have been “fooled” according to the skeptics. It’s funny how the gullible think they can recognize the gullible, but it doesn’t work that way.

Update: I see that the China Meteorological Agency also put out a 2010 year end summary noting the extreme weather, and putting it down to global warming. For example:

Extreme rainstorms followed the hot weather. Ninety-seven weather stations around China reported record-breaking daily rainfall, and 133 stations broke their annual records. Only seven record-breaking daily rainfall figures were reported from 2000 to 2009.

Something wrong with the universe?

This intriguing article “The Truth Wears Off”appeared in the New Yorker before Christmas, but I’ve only just read it.

It’s all about the “decline effect”, whereby effects that initially appear strong in experimental studies seem to start declining in effectiveness as more and more scientists try to replicate the original findings.

Some (or all) of this is understandable in terms of better experimental set ups, and publication bias, which means that it’s much easier to get an apparently new effect published than a study that has a negative result.

But the article is of most interest when discussing cases where the scientists who first made a positive finding discover that they can’t replicate it themselves. A good example is given from parapsychology, where pioneer JB Rhine initially seemed to have a star subject, but he subsequently seemed to lose all of his ESP powers. Sure, the simple explanation may be that, even though Rhine may have thought the replication set up was identical with the previous one, it really wasn’t, and a trick the subject was previously using subsequently failed him. But it does seem a little odd to me that Rhine wouldn’t find the trick in a case like this: one feels sure that this would be more satisfying in its own way than admitting that he can’t explain why a subject lost his power.

There are other examples of this given in the article, and from less contentious fields than parapsychology. It’s well worth a read.

Talk of all this couldn’t help but remind me of Rupert Sheldrake and his odd morphic resonance idea. In short, he believes that you can scientifically show that it becomes easier to acquire knowledge as more and more subjects learn it, be they birds, dogs or humans. (And, of course, in his theory, it’s not via simple imitation of the first creature who learnt the talent.) A genuine decline effect would seem to be the opposite of that.

A possible example of the decline effect that came to my mind was the original cold fusion experiments, and perhaps some of the subsequent ones too. These are not mentioned in the article, however.

If it were true (the decline effect) I guess it could be explicable (warning: wild speculation about to embarked upon) by either:

a. the universe really being a computer simulation game run by a mega intelligence that changes the rules for some obscure purpose while the program runs; or

b. God, his opposite number, or aliens (take your pick) finding it important that certain things not be discovered by humans until the time is right. I personally like the idea of undercover teams of angels, demons, aliens or Men in Black interfering with important experiments in very subtle ways to confound humans at particular points in time. Of course, this may make “sense” for something fundamentally groundbreaking like the discovery of ESP, or perhaps cold fusion, but why it should apply to the effects of antipsychotic drugs would be rather harder to explain.

I guess there is probably some science fiction (or supernatural fiction) that has been written along the lines of b, but I can’t bring any to mind. The nearest may be the idea in the Day the Earth Stood Still that aliens would give us a warning to mend our ways by one spectacular demonstration of their power. But that was far from an discrete way of interfering. And I do recall David Brin wrote “The Practice Effect”, in which inanimate objects get better with “practice”, but again that is more akin to Sheldrake’s idea than a decline effect.

A decline effect has better fiction possibilities than morphic resonance, and maybe that is its most endearing feature.

Mochi deaths 2011 (this year with video, and other “Japan is shrinking” news)

Happy New Year, everyone, and once again, condolences are due to those in Japan who just lost someone due to the annual New Year’s mochi eating habit.

Yes, as my Google search ranking for “mochi deaths” remains very high (number one in fact, something I acknowledge as a dubious distinction), I know that I have visitors waiting for this annual post.

But as with last year, it seems that the English Japanese news media have lost interest in providing the numbers of (usually elderly) Japanese residents who choke on their New Years mochi.

So again I have had to resort to searching in Japanese, this time with the ever helpful Google translate. It seems the numbers in the Tokyo area (see 3rd story at the linked page to Yomiuri Shimbun), at least, are pretty much as high as ever:

Between one or two days in Tokyo, Kanagawa, Saitama, Chiba, and Wakayama prefectures of five, died choke on rice cakes from a total of 10 elderly people.


Tokyo Fire Department is "good hair cut is a small cake, for the elderly and children, accompanied by family members want," and has called for.

According to the agency, in Tokyo, the 24 people taken to the hospital by 8:00 pm two days, killing six of them. The 70 year-old woman died and five 95-year-old man 82. Five of them were at home eating rice cake.

In the other 4 provinces, 61 hours a day to choke on rice cakes 89-year-old male and female four people died.

So, the take home message from that seems to be: 10 dead, at least 24 taken to hospital. You can watch video of this deadly New Year's treat here at the link to Fuji TV. Fortunately, none of the participants keel over and die for the crew filming it.

There is another TV news story (see link to Japan TV NNN) about it, sadly showing an elderly person in a nursing home, by the looks, not being fed mochi. It is, I suppose, a hard story to illustrate well, but still I wish they had come up with something better than this.

Anyhow, my searching around hasn’t found any obvious links to the national mochi death toll this year, but if there were 10 dead around Tokyo, the total for the entire country must be considerably higher.

It’s no wonder that articles like this, warning of the danger, appear just before New Years. Incidentally, maybe this gives an indication of how many people die nationally from mochi, if I can trust Google Translate:

According to the Tokyo Fire Department, four years until 2009, the number of cases in food spending by 4719 the risk of suffocation. Of these, 444 of rice accounts for about 10 percent, are concentrated in the month of January to about 40% of the 171. The ratio becomes more severe 53%, and 70 years or older in most cases by a lot of food.

The Cabinet Office Food Safety Commission in June this year, the probability of risk of suffocation on food, and summarizes the results of the cake at highest risk. And is calculated by assuming 100 million people took a bite, the cake is to be up to 7.6 at the frequency of accidents….

According to the Ministry of Health, Vital Statistics, the number of deaths due to suffocation incidents of food in 2009 4679 people. Account for nearly 90 percent of those over 65.

So, if Tokyo Fire Department has about 4,719 deaths over four years from all choking, and the total national figure is about the same per year, maybe we can assume the national New Year's mochi death toll is about 3 to 4 times the Tokyo average? Well, someone with actual Japanese ability can correct me, but it seems a fair guess.

Onto more death in Japan news, the Japan Times notes the following:

A total of 4,863 people died from traffic accidents in 2010, down 51 from the previous year, according to preliminary data from the NPA.

So, roughly the same amount of Japanese die annually in car accidents as from choking? How does that compare to other countries? Well, it appears well above the American choking rate:

According to the National Safety Council, choking remained the fourth leading cause of unintentional injury death in the United States as of 2004. In 2006, a total of 4,100 deaths (1.4 deaths per 100,000 population) from unintentional ingestion or inhalation of food or other objects resulting in airway obstruction was reported.

But the real point I was linking to the Japan Times article was due to the coverage on the shrinking Japanese population generally:

Death record reset KYODO An estimated 1,194,000 Japanese died last year, the most since record-keeping began in 1947, according to the latest health ministry data.

The data also said an estimated 1,071,000 babies were born 2010, up slightly from 2009.

The difference between births and deaths — 123,000 — also set a record high, blowing by the previous record of 71,830 set in 2009.

"The number of deaths is on the rise due to aging and the number of births will not grow because of a decline in the population of women who give birth," a Health, Labor and Welfare ministry official said.

The difference "will continue to be greater in the future," the official said.

In 2009, total deaths fell by 542 from 2008 to stand at 1,141,865. In 2010, however, total deaths surged by around 52,000 as elderly people succumbed to the hottest summer on record, the official said.

Japan's population decline has certainly taken a surge for the worse, by the sounds. (It's also interesting to note how many deaths they blame on the hot summer, even in a country where small houses and apartments make air conditioning easier and more economical than in countries like Australia.)

The Japan Times also recently ran an interesting opinion piece noting that Japan's fertility decline was by no means unique, being shared by other East Asian countries (Korea and Taiwan both, oddly enough) as well as strong welfare state countries such as in Scandinavia. This is true enough, but it still doesn't address the major issue of Japan being reluctant to take substantial immigration. It's not like they're going to be short of houses anytime soon.

1980’s justified

Long term readers may recall that, apart from They Might be Giants, my other main pop music interest has been David Byrne and Talking Heads.

Tonight, I was looking at a Youtube of Once in a Lifetime, as I was going to show it my son.  But he was too busy hunting dinosaurs on the iPad, so he didn’t pay much attention.  I’ll get him to watch it yet.

But the thing of interest is that this upload of the clip (done in Jan 2010) is still attracting recent comments.  (I presume it must the version that everyone watches when they search for it.)

And generally speaking, nearly everyone commenting seems young, but very appreciative.   I like this one:

my parents will do the arm thing and say "same as it ever was" all the time!! LOLOL

And this comment:

Such a cool video even till today

and

 Best. Video. Ever

That’s nice.  I feel the 1980's doesn't have much to be ashamed of after all.

Dr Who Christmas

I'm not the world's biggest Dr Who fan, but still, I like to comment on it sometimes.

This year's Christmas special was, I thought, a very pleasing combination of mad, clever, funny and touching. It was also, I thought, much better directed than some of the previous season; it hung together pretty well.

Let's hope the forthcoming season works a tad better than the last, which had it moments, but not quite enough of them.

Must catch up with TMBG

My favourite band, They Might be Giants, spend a lot of time doing kids albums lately, which I don’t usually buy, even though they write some pretty catchy stuff that usually gets them a Grammy nomination.

But I think I will get the current one: Here Comes Science. Most of the songs seem to be up on Youtube, and I like many, including this one:

And I’ve also found a video for another song of there’s from a couple of years ago. Since we all like drinking and smoking puppets, it’s worth a look:

Watch it while you can

It was a couple of years ago that I mentioned I had seen (and then bought) the DVD for the 1999 "movie" of Joseph and the Amazing Technicolor Dreamcoat. As that happened around Christmas, it's become a minor family tradition to watch it at the this time of year; hey, it might not be Christian, but the story is not inappropriate for the season.

We all still really like it: as I've said before, I think it does a filmed musical stage production in about as perfect a way as I can imagine.

As for the musical highlight, I've always really liked this song (A Pharoah
Story) at the start of the second act, sung here by the lovely Maria Friedman. While this part is not staged in any way to give you an impression of what the rest of the DVD production looks like, it sounded pretty good through my computer speakers, so have a look.

I see that an earlier Youtube I had up has been pulled for breach of copyright. I expect the same fate this one too, especially as the guy seems to have put the whole movie on Youtube. That really must push the patience of Mr Lloyd Webber. So enjoy while you can:

Three videos

1. Sega can be played in all sorts of places now (read the comments following this post too: quite witty.)



2. The funniest ads I saw all year, from Gruen Transfer.

3. I never cared for Rudolph anyway (you can skip through the first minute or so)

Not exactly Christmassy

I’ve been looking around The Guardian’s Comment is Free Belief section, and it’s pretty good.  (Generally speaking, I preferred The Guardian’s website when they gave more prominence to CIF articles on their main page.  Now you have to make the extra click, and I miss a lot of stuff there.)

This article about modernising Hinduism is pretty interesting.  Apparently, the Hindu America Foundation has a report that tackles the caste system head on.  I was interested to read this part:

Noting that there are defenders of the caste system, not just the curmudgeon and cruel among Hindus, but the likes of Voltaire and Diderot who fought against the monotheistic intolerance of Christians and Muslims, to sociologists like Louis Dumont who argued that the "distribution of functions leads to exchanges", to the great Indophile, Alain Daniélou who argued that caste does not equate to "racist inequality but… a natural ordering of diversity," the HAF report argues that a birth-based hierarchy is unacceptable, that inequities against and the abuse of the Dalits/SCs is a human rights issue, and that the solution to this social ill is available within Hindu sacred texts themselves, and that Hindus should be at the forefront of putting an end to the system of birth-based hierarchy as well as taking the lead in energising the Dalit community to fight discrimination.

It's always good to see how outsider intellectuals justified crap systems.

Another ocean issue

Oh, that's good. [Sarcasm] Another way in which ocean pH may be a problem:
Scientists already know that a drop in ocean pH affects the carbon cycle, reducing the carbonate ions that organisms like corals, mollusks and crustaceans use to build shells and external skeletons. Now, a new study shows that a CO2-induced increase in acidity also appears to disrupt the marine nitrogen cycle. The finding, to be published December 21 in the Proceedings of the National Academy of Sciences, could have ramifications for the entire ocean food web.
But what practical effect this may have is completely unclear:
Nitrification decreased, compared to controls, in all experimental cases, with the effect ranging from an 8 percent reduction to a 38 percent reduction. "What we saw is almost uniform across the ocean, or at least in all the experiments we conducted, which seems to suggest this is fairly consistent effect," says Beman. Importantly, in some cases the change was quite large. "So it could have a pretty substantial effect on how nitrogen is cycled in the ocean," he says.

One potentially positive effect could be a reduction of nitrous oxide—marine nitrification is a relatively big source of this greenhouse gas. "But the larger, much more difficult things to predict are the connections to other organisms and processes," says Beman. Less nitrification would make fewer nitrates available to the plants and other organisms that use them to make vital proteins, making it more difficult for them to thrive. This in turn means less food would be available to the animals that eat those nitrate-using organisms, and so on up the food web.

Oyster and coral alert

Time for some ocean acidification news.

Oysters grown on the West coast of American have been having a hard time.  As this story noted in 2009:

In 2005, when most of the millions of Pacific oysters in this tree-lined estuary failed to reproduce, Washington’s shellfish growers largely shrugged it off.

In a region that provides one-sixth of the nation’s oysters – the epicenter of the West Coast’s $111 million oyster industry – everyone knows nature can be fickle.

But then the failure was repeated in 2006, 2007 and 2008. It spread to an Oregon hatchery that supplies baby oysters to shellfish nurseries from Puget Sound to Los Angeles. Eighty percent of that hatchery’s oyster larvae died, too.

Now, as the oyster industry heads into the fifth summer of its most unnerving crisis in decades, scientists are pondering a disturbing theory. They suspect water that rises from deep in the Pacific Ocean – icy seawater that surges into Willapa Bay and gets pumped into seaside hatcheries – may be corrosive enough to kill baby oysters.

Well, now it seems the suspicions of high CO2 having something to do with this may have been confirmed.  Someone had the good idea to actually takes measurements of the water used:

Increased pCO2 and decreased pH have been shown to negatively impact larval development in C. gigas (Kurihara, 2007). Periods of elevated pCO2 in May and June 2010 correlated with commercial losses at WCH.

In another study, decreased pH was shown to decrease shell strength of pearl oysters (although it doesn’t appear that they looked at the pearls themselves.)

And for corals, another recent study indicated that a combination of even modest water temperature increase and lower pH has a big effect on coral growth and survival:

Holger babysat 40 of the baby corals for 42 days under four different conditions: In the first tank, the researchers simulated 1C of ocean warming; in the next, they simulated ocean acidification by bubbling carbon dioxide through the tank to lower the pH by 0.25; the third combined this warming and acidification; and a fourth tank maintained current ocean conditions as a control.

“The different conditions had absolutely no effect on the ability of the larva to settle – to stick to the rock surface – which may be good news for people who are trying to grow coral gardens,” Aaron says.

But post-settlement, some of the young coral polyps were showing the effects ‘global warming’.

“The biggest surprise was that neither temperature alone, nor acidification alone had a big effect on the growth or survival rate [95%] of the coral, even though the warming prompted zooxanthallae expulsion as expected,” Aaron says. “Once we combined this moderate warming and acidification, though, we saw significant impacts: growth rate of the polyps – for both the skeletal and soft pulpy mass – plummeted to almost half of the rate seen under the other three conditions, and they were twice as likely to die [90% survival rate].”

The link to the actual study abstact is here.

And finally, if these Europeans have it right, the decrease in aragonite saturation (important for some corals and shellfish) is going to be on a rapid downward spiral this century right around the world:

Sweet bug

It seems this has been on Youtube for a while, but it just made an appearance on Cute Overload.

I reckon it looks remarkably like how you would expect a kitten to act. (In reality, as some people at Youtube have noted, it was probably thinking they were aphids it was trying to kill. But then, kitten play is just build up to backyard wildlife murder, so what the hey...)

Seems a nice man

I recently mentioned Geoffrey Rush as an Australian actor who actually doesn’t bother me.  (He has managed to get through the insidious effects Australian films have on me.)  I see today that he has an interview in LA Times which is pretty interesting.  I liked this part about his first (short) trip to LA:

Tell me about the first time you ever set foot in L.A.
It was in 1996. James L. Brooks had seen a copy of Shine before it was released, and he asked to meet with me. So I flew over and spent six hours with him. He had a little camera, and I read and did improv, and then I just got back on the plane and came home. It was weird—there was a limo waiting to take me to my $500-a-week theater job.

What was your impression of the city from those six hours?
Well, I’m suddenly driving down Pico Boulevard. You see the palm trees, and you think, Oh my God, it’s just like Brisbane but bigger! It didn’t seem unfamiliar, because it’s known to us through so many movies. It just had a complete air of unreality, and I thought, This is kind of an adventure. [Brooks] gave me some Simpsons booty to bring back. I got [an animation] cel and some shirts and stuff. It was a fun, amazing weekend.

Must be a fantastic Happy Meal toy this week

Climate notes from all over

Yes, it's cold in England and much of Europe, and climate change skeptics are poking fun at those who in the last decade predicted the virtual end of winter snow for those countries currently under a lot of it.

Yet, Real Climate has a post about the ways that it may indeed be all related to AGW, and in particular to do with sea ice over Canada way. But it's all very complicated and no one knows for sure.

Now, 2010 is bound to be high on global average temperatures, but it does seem a year most notable for sudden extremes in all aspects of weather - the Russian heatwave, the Pakistan floods, the one in a 1000 year flood of Tennessee. And now England and Europe being unusually cold.

Given the slow but (on the longer scale) steady progress of global temperatures (Tamino has an excellent post showing how all the temperature data sets collected and calculated in different ways are still all following the same path,) it will be interesting to see whether the public over the next year or two becomes convinced of global warming not so much due to high local temperatures, but more because of erratic weather swings.

Meanwhile, Judith Curry's blog continues to be a big puzzle. As someone commented somewhere, it's like she decided to rebuild climate science from the ground up. On the positive side, she doesn't dispute the very, very basics of CO2 as a greenhouse gas, but when she gets into anything else, it's actually very hard to tell where she is going. (In fact, some posts, talking about science generally, give the impression she is seeking to rebuild science itself from the ground up.) She seems to find many things "interesting" and worthy of her looking into further, but at this rate is seems she will come to some conclusion by about 2020.

None of her mainstream climate critics have said much about her lately, a bit to my surprise, but Judith went to the AGU meeting last week in San Francisco, and her post showing her slides ends with these two:

Slide 14

In conclusion: The drive to reduce scientific uncertainty in support of precautionary and optimal decision making strategies regarding CO2 mitigation has arguably resulted in:

  • unwarranted high confidence in assessments of climate change attribution, sensitivity and projections
  • relative neglect of defining and understanding the plausible and possible worst case scenarios
  • relative neglect of decadal and longer scale modes of natural climate variability
  • and conflicting “certainties” that result in policy inaction

Slide 15

A way forward is the decision analytic framework of robust decision making under deep uncertainty, which emphasizes scenario discovery and uncertainty analysis and identifying a broad range of robust decision strategies.

Implications of such a strategy for climate research are an increased emphasis on:

  • exploring and understanding the full range of uncertainty
  • scenario discovery using a broader range of approaches
  • natural climate variability, abrupt climate change, and regional climate variability
Clear? No, it wasn't to me either.

But - I am happy to see that James Annan, who was strongly critical of Curry's "Italian flag" post several weeks ago (I don't think she has finished talking about them yet) saw her AGU talk, and has this to say about it:
He also emphasised the importance of only speaking in areas where you had earnt credibility based on your published record, which formed an interesting backdrop to Judith Curry's talk later that day. She devoted her time to accusing the IPCC of ignoring the tails of the pdfs of climate sensitivity that were clearly presented in the very figure that she repeatedly referred to and explicitly emphasised in the summary ("values substantially higher than 4.5C cannot be excluded"), then read out a few cartoons and finally, literally out of nowhere, concluded that therefore they had underestimated the magnitude of decadal variability and that their detection and attribution results were unsound! Really, I'm not making this up, it was actually how it happened. These latter topics were first introduced on her concluding slide and there was no hint of supporting argument. She also talked about the "modal falsification" of Betz 2009, (which I haven't read but just googled now, is there a free version somewhere?) so I asked if and how this "falsification" (and she used the scare quotes herself) was distinct from assigning a low posterior probability in a Bayesian sense. She replied that it could be considered the same, at which point some of the audience were shaking their heads and others were nodding in agreement. From which I conclude that nobody, including Judith, knows what Judith means. Unfortunately, she didn't seem to be anywhere to be found at the end of the session and I didn't see her at any of the other relevant sessions where people actually dealing with these sorts of issues were actually presenting concrete results.
So, I am not alone in not being able to make head nor tail of Curry, and my lack of science qualifications are not the reason why. Romm's description of her as a "confusionist" seems as apt as ever.

Sequelitis

Well, it's good to see my complete puzzlement as to why Disney would chose to make a sequel to Tron is shared by many critics. As Dana Stevens writes:
The idea to make a sequel to the 1982 movie Tron—which was a hit neither with most critics nor with the public and which has amassed, at best, a campy cult following among a niche of gamers and sci-fi fans—is an arrogant overestimation of the original's value. The grandiose hype for Tron: Legacy (Disney Pictures) reminds me of those Manhattan "vintage" stores that try to trick you into paying $120 for a stained raincoat because, hey, it's old! Well, no, I don't want an expensive old raincoat that was unremarkable the first time around, nor do I want an expensive ($170 million) remodel of a 28-year-old matinee flick that was forgotten for a reason.
I agree totally, although I would add that I didn't realise there was a market for old raincoats in Manhattan.

Mind you, Disney has history with making sequels to bad movies. Recently, my wife borrowed for the kids the 1975 movie Escape to Witch Mountain. I had the vague idea that it had been a moderate success for Disney, as they had made a sequel (Return from Witch Mountain), which I had never seen either.

Well, I can tell you, Escape is an extraordinarily bad kid's film, even by the standards of the normal poor regard Disney had developed for its live action product in the 1970's (before the studio underwent its animation led recovery in the 1980's.) It has simply excruciating acting, and special effects that make those in (TV) Lost in Space look sophisticated. Yet, the DVD still has the "extras" on it, with interviews with the director, the child actors, etc. It's not even so bad that its good: it's just bad with no redeeming features.

But: do not get confused with Race to Witch Mountain, the recent Dwayne Johnson Disney vehicle, which really is quite good.

Ahead of the media

Jack Shafer in Slate notes that there has been recent US media attention to the illicit use of nutmeg to get high. He goes into the history of the use of the spice for this reason.

I would just like to point out that, for anyone who hadn't heard of this before, if you were reading my blog in 2006, you would have known this unusual fact already.

Stay ahead of the media, and learn oddball facts. Read this blog.

This will only be understood by a limited number of people. The rest of you shouldn’t look.

No holes, yet

Nature reports about the LHC:

Predictions of mini black holes forming at collision energies of a few teraelectronvolts (TeV) were based on theories that consider the gravitational effects of extra dimensions of space. Although the holes were expected to evaporate quickly, some suggested that they might linger long enough to consume the planet. But scientists at the Compact Muon Solenoid (CMS) detector now say they found no signs of mini black holes at energies of 3.5–4.5 TeV. Physicist Guido Tonelli, the detector's spokesperson, says that by the end of the next run, the LHC should be able to exclude the creation of black holes almost entirely.

That's good; but let's hope that it doesn't unexpectedly create a naked singularity or two: I don't think anyone has any sound idea what that could lead to.

Tolkien in Narnia

So, Voyage of the Dawn Treader has attracted very mixed reviews, and, I thought, was certainly the end of the series after the first weekend box office in the States was only about $24 million: half that of the first two movies in the series. 

Yet, overseas box office has been surprisingly strong, bringing the total take to over $100 million already.  The studio says it’s happy; so who knows, maybe  there will be another.  I can’t remember a single thing about The Silver Chair, though, so I have no idea how readily it might be adapted.

Anyhow, that’s not the main point of the post.  Narnia movies always stir up debate about whether the religious themes are too obvious or heavy handed.   (It’s a handy criteria for judging reviews of the films:  if they complain about them being so Christian, they can safely be ignored.  It’s like complaining to the waiter that there’s tomato in your bolognaise sauce.) 

This time around, I have enjoyed some of the comments in a Guardian story on this aspect of the movie.   Having the readership that it does, there are many who complain about the Christian element and virtually consider it a corruption of children to have such ideas appear in their fiction.  But I liked this response:

Still think its a bit amusing (and strange) how people complain about Christian themes being 'corrupting' when woven into the subtext of one narrative or another - yet Lady Gaga gyrating and wagging her bacon clothed crotch about while singing 'lets have some fun this beat is sick, I wanna take a ride on your disco stick' (And yes seven year old kids do mimic the dance moves and sing the lyrics completely innocent of any ulterior connotations) doesn't conjur nearly the same level of pompous ire. I ain't got a problem with Lady Gaga necessarily (though as you will have guessed I'm not much of a fan of her music), just think the contrast in response is amusing.

And, of course, you can't have a discussion of Narnia without comparisons with Tolkien breaking out. Readers may recall that I belong to the (seemingly) very small club known as People Who Think Tolkien is Vastly Over-rated in Every Respect. The movies bored me;  before they came I had tried to read the first book of LOTR twice; and when that didn’t work tried the Hobbit. Bored and gave up for lack of interest every time. I haven't spent a lot of time trying to analyse why: I just think he's stylistically a dull writer, and I just don't understand what it is, thematically, that people respond to.

But now,  in this Narnia thread, someone made a comment that rang very true to me:

I like many posters on her, I grew up in an atheist family. I discovered the books through friends at school, and thoroughly enjoyed them, more than the Tolkein books as the main characters weren't exclusively male, and the adventures didn't drag on and on ad-nauseum, with battle followed by journey, followed by battle etc. Also, good and evil were things that could happen because of the choices a person made; not like the Tolkein books, where good and evil, are just depersonalised 'forces' which people either succumb to or not, which I think is a far more primitive, 'superntaural' take on morality, which avoids the truth, that people chose to act in a particular way, but can also change and chose not to.

I have to admit that, not having got more than about 100 pages into LOTR, I am not one to really judge, but that explanation of the treatment of good and evil in Tolkien sounds right to me, and may be why I don’t respond to him.

And now let’s end with a couple of Guardian readers who complain about the Anti-Lewis (Philip Pullman’s), books (which I haven’t read, but like to kick anyway):

Narnia might be a bit shit but The Golden Compass is the most preachy nonsense for years. My nieces/nephews all loved Harry Potter and Narnia, but really did think they were getting a lecture from PP

I couldn't agree more. I read his trilogy, which started off well enough, but not too far into book two I felt that at times I might as well just have had Pullman shouting "Religion is bad!" in my face. His message was as subtle as a kick in the balls and really put me off (even as an atheist).

Wednesday’s List

* Regarding Hugh:   So, Hugh Jackman nearly took out an eye in front of Oprah’s audience.   Which leads me to wonder:  why don’t I like Hugh Jackman as a screen presence?   He doesn’t seem to be the jerk in real life that I always half suspected Mel Gibson was.  Is it just that he has appeared in Australian films, to which I am famously allergic?  I don’t think so; Geoffrey Rush and Noah Taylor turning up in a foreign movie doesn’t bother me.   Is it because he has become the international poster boy for iced tea?   Maybe:  the only wussier product a some time action man could have chosen to endorse is Max Factor.   No, I’m not entirely sure, but there is something about him I don’t care for. 

Ross looks on the bright side:   Ross Gittins goes against the popular wisdom and tells Australia that selling minerals instead of making things is not that big a problem for our economy.  Must be an outbreak of Christmas optimism.

Image I’d rather not see:   for some reason, German doctors thought it would be a neat idea to watch a live human birth via MRI.  The resulting x-ray-ish image makes the world’s creepiest new born baby photo.

An unusual explanation for the Holocaust

I have a vague recollection of reading before that Hitler might have had syphilis, but I’m not sure if I had heard of the theory that it was catching it this way which may have led to his anti-Jewish obsession: 

An encounter with a Jewish prostitute in Vienna in 1908 may have given Hitler neuro-syphilis and provided the 'deadly logic and blueprint for the Holocaust' as well as giving him a reason to attempt to eliminate the mentally retarded, according to evidence presented at the Royal College of Psychiatrists.

That theory supported by 'ample circumstantial evidence though no final proof', according to a team led by Dr Bassem Habeeb…

There has been speculation that Hitler had the infection since his personal doctor, Theo Morrell expressed his own suspicion in his private diary. But the theory has never been rigorously examined, say the researchers.


'But if Hitler's life is looked at through the lens of a
syphilis diagnosis, one clue leads to another until a pattern of infection and progressive infection emerges, a disease that may have defined him from youth as an outsider and that progressively ravaged his body and mind.

Hitler put syphilis high on his political agenda, devoting 13 pages to the disease in Mein Kampf. The job of 'combating syphilis… the Jewish disease… should be the task of the entire German nation,' he wrote. 'The health of the nation will be regained only by eliminating the Jews'.

The theory might hold up better if it were not believed by the very nutty Dr Morell.  In fact, I see from his Wikepedia entry that at least two of his treatments in 1944 may have directly sent Adolf over the edge:

During his interrogation after the war, Morell claimed another doctor had prescribed cocaine to Hitler and at least one other doctor is known to have administered it through eyedrops after he requested it in the hours following an almost successful assassination attempt on July 20, 1944. Cocaine was routinely used for medical purposes in Germany during that time but Morell is said to have increased the dosage tenfold - despite this the concentration was still weak as the eyedrops were only 1% cocaine. Overuse of cocaine eyedrops has been associated with psychotic behavior, hypertension and other symptoms; given the weak dosage, it's more likely they were caused by Methamphetamine of which these are also common symptoms. However historians have generally tended to discount any effects of Morell's treatments on Hitler's decision-making.

Anyhow, I can see a new poster slogan for safe sex: "Avoid World War! Use a condom."

Tuesday’s collection

Geosequestration – Just Give Up

A geophysicist talks about how pumping large amounts of CO2 into the ground is often likely to cause sesmic activity, and although it may not be much on the surface, it may be enough to break the resevoir itself. But the most obvious problem is the sheer scale you would need to make a difference:

The other complication, Zoback said, is that for sequestration to make a significant contribution to reducing carbon dioxide emissions, the volume of gas injected into reservoirs annually would have to be almost the same as the amount of fluid now being produced by the oil and gas industry each year. This would likely require thousands of injection sites around the world.

"Think about how many wells and pipelines and how much infrastructure has been developed to exploit oil and gas resources over the last hundred years," he said. "You need something of comparable scale and volume for carbon dioxide sequestration."...

There are two sequestration projects already underway around the world, in Norway and Algeria, and so far they appear to be working as planned. But Zoback said 3400 such projects would be needed worldwide by midcentury to deal with the volume of carbon dioxide that we will be generating. "Finding that many ideal sites around the globe is not impossible, but it is going to be a tremendous challenge," he said.

*   Ron Paul – rants ahead

Slate notes that Ron Paul getting a position on a House financial committee is not universally welcomed by libertarians:

"Republicans stashed him in this job because they don't want him making more important decisions," said Megan McArdle, a prominent libertarian blogger and economics editor of the Atlantic. "He cares passionately about monetary policy, which most Republicans don't care about. But when you look at his speeches, he doesn't understand anything about monetary policy. He might actually understand it less than the average member of Congress. My personal opinion is that he wastes all of his time on the House Financial Services Committee ranting crazily."…

The anti-Paul case consists of one simple argument—he sounds crazy—and one complex argument, which is that he's distracted libertarians and Tea Partiers by focusing their ire on the easily demonized Fed.

Monday madness, and other stories

*   There is something seriously wrong with Liz Hurley.  A psychiatric consultation is strongly recommended, and if she doesn’t go voluntarily, a kidnapping intervention by her friends would not result in any conviction in any court of law.

Neil Armstrong writes an email talking about his trip to the moon.  He wants NASA to go back there.  The only thing standing in our way are politicians.

* There was a charming story in Slate recently about a 100 year old guide called “How to Write Fiction”.   Slate says “…much of Cody's advice remains startlingly recognizable: It's Writer's Digest with a handlebar mustache.” 

The article notes that there was a lot of advice around at the time directed to women in particular.  I liked this section:

The London women's magazine Atalanta launched a regular "School of Fiction" column, and its advice from 1893 on pitching remains as useful and unheeded as ever: Keep your pitch short, nail down a tangible story first, and for god's sake read the magazine before you submit to it. Ladies were then invited to try such spry writing exercises as an imagined 500-word dialogue "on the Equality of the Sexes, between Miss Minerva Lexicon, M.A., an apostle of Progress, and Miss Lavinia Straightlace, of the Old-Fashioned School."

* From the Christian Science Monitor, a story of, um, dedication to art (or at least controversy:

Swedish cartoon artist Lars Vilks, who became the target of an alleged international murder plot for his 2007 cartoons of Mohammed as a dog, again angered Muslims Tuesday by showing an Iranian film that depicts the Prophet entering a gay bar.

When Mr. Vilks showed a scene from the film at Uppsala University in Sweden, a protester charged the dais and hit him, breaking his glasses. Police were forced to detain or pepper-spray some unruly members of the crowd as other protesters yelled "Allahu Akbar" – "God is great."

For Mr. Vilks, who has booby-trapped his own house and says he sleeps with an ax beside his bed, the right to unfettered speech – regardless of whether it offends Muslims – is a point of principle.

I am kind of curious as to what Mohammed does in the gay bar in an Iranian film.

Science, gold and ducks

It’s kind of surprising that there is still a far amount of uncertainty about the formation of planet Earth.  I didn’t realise this, for example:

The planets formed when tiny rocks collided, forming ever larger lumps. Then, after Earth was born a second planet about the size of Mars crashed into it. This cataclysmic shock blasted a huge cloud of material into orbit, where it coalesced to form the moon.

This neatly explains the moon, but poses a problem. The collision re-melted the solidifying Earth, allowing heavy materials like iron to sink into the core. But some elements, called siderophiles, dissolve in molten iron, including gold, platinum and palladium.

"We shouldn't have any siderophiles in the crust or mantle," says William Bottke of the Southwest Research Institute in Boulder, Colorado. "But actually we see them in surprising abundance."

The obvious solution is that they arrived after Earth cooled. If so then the moon should have siderophiles too, and it doesn't. Rock samples show that it has 1200 times fewer than Earth.

The article notes that the idea is that the earth was hit by a few, really big, gold bearing planetoid things, but they missed the moon on the way in.

This is a pity.  Having an gold bearing region on the Moon might make have made space exploration take a different path.

And, come to think of it, this reminds me of the classic Carl Barks Uncle Scrooge comic “The 24 Carat Moon” which I read as a child.  No doubt this was why I wanted to post about this, before I even remembered the comic.

An important paper

Real Climate has an important post up about a paper by Dessler out this week on clouds and climate sensitivity.   The actual paper can be read here.

Basically, it analyses satellite data and suggests that increased clouds will not protect the earth from increasing temperatures, as Spencer and Lindzen have argued.  Roy Spencer also had a paper analysing satellite data out recently; until now, response to it had been strangely quiet.

Dessler does acknowledge that it will be a long time before precise long term cloud feedback is pinned down with certainty.   But the post in Real Climate is  well worth reading because it seems to put Spencer’s opinion in its eccentric context:

After reading this, I initiated a cordial and useful exchange of e-mails with Dr. Spencer (you can read the full e-mail exchange here). We ultimately agreed that the fundamental disagreement between us is over what causes ENSO. Short paraphrase:

Spencer: ENSO is caused by clouds. You cannot infer the response of clouds to surface temperature in such a situation.

Dessler: ENSO is not caused by clouds, but is driven by internal dynamics of the ocean-atmosphere system. Clouds may amplify the warming, and that’s the cloud feedback I’m trying to measure.

My position is the mainstream one, backed up by decades of research. This mainstream theory is quite successful at simulating almost all of the aspects of ENSO.

Dr. Spencer, on the other hand, is as far out of the mainstream when it comes to ENSO as he is when it comes to climate change. He is advancing here a completely new and untested theory of ENSO — based on just one figure in one of his papers (and, as I told him in one of our e-mails, there are other interpretations of those data that do not agree with his interpretation).

Thus, the burden of proof is Dr. Spencer to show that his theory of causality during ENSO is correct. He is, at present, far from meeting that burden. And until Dr. Spencer satisfies this burden, I don’t think anyone can take his criticisms seriously.

It’s also worth noting that the picture I’m painting of our disagreement (and backed up by the e-mail exchange linked above) is quite different from the picture provided by Dr. Spencer on his blog. His blog is full of conspiracies and purposeful suppression of the truth. In particular, he accuses me of ignoring his work. But as you can see, I have not ignored it — I have dismissed it because I think it has no merit. That’s quite different.

Something comes from nothing (take that, Rogers and Hammerstein)

An article at PhysOrg describes a way of making a heap of particles out of nothing. Takes a fair bit of energy though, so I don’t think we’ll be building a second earth this way anytime soon.

In other “where did this all come from?” news, I meant to note last week that Roger Penrose and a collaborator had published a paper showing nice circles in the universe’s cosmic background radiation, with the following implication :

The discovery doesn't suggest that there wasn't a Big Bang - rather, it supports the idea that there could have been many of them. The scientists explain that the CMB circles support the possibility that we live in a cyclic universe, in which the end of one “aeon” or universe triggers another Big Bang that starts another aeon, and the process repeats indefinitely.

However, according to physicist (and irritating anti-religion polemicist in the culture wars) Sean Carroll, there are two papers out already saying that the circles mean no such thing. Most interestingly, he writes how he’s got his hands on Penrose’s (recent, I think) book, and just can’t see how Penrose’s idea of a cyclic universe is supposed to happen. (Unlike the old view that the universe would contract to a Big Crunch, and maybe bounce back from that, it would seem everyone is now accepting that the universe dies in an ever expanding wimper.):

The basic point is this. The very early universe is smooth. The universe right now is lumpy, with stars and galaxies and black holes all over the place. But the future universe will be smooth again — black holes will evaporate and the cosmological constant will disperse all the matter, leaving us nothing but empty space. (Just wait about 10100 years.) So, Penrose says, we can map the late universe onto a future phase that looks just like our early universe, simply by a conformal transformation (a change of scale). Do this an infinite number of times, and you have a cyclic cosmology — the universe goes through a series of “aeons” that start with a smooth Big Bang, get lumpy as structure forms, smooth out again, and then gets matched onto another smooth Big-Bang-like phase, etc.

If you’re sketchy on that last bit, join the club. Sure, mathematically we can map the smooth late universe onto the smooth early universe. But what physical process would actually cause that to happen? Despite having the book in my hands, I’m still unclear on this. (I absolutely confess that the answer might be in there, but I simply haven’t read it carefully enough.) While the early and late universes are both smooth, they are very different in other obvious ways, such as the energy density. What causes the low-density late universe to come alive into something like the high-density early universe? Something like that happens in the Steinhardt-Turok cyclic universe, but in order to make it happen you need to specify some particular matter fields with very specific dynamics. This isn’t a trivial task; there are things you can try, but they generally are plagued by instabilities and singularities. I don’t see where Penrose has done that, so I’m not even sure what there is to be criticized.

Penrose is getting old, but he remains a well respected figure. But it would be good to know how he thinks his cycles may happen.
