Bee at Backreaction has a couple of good posts up recently, one about theorising about how stable the photon may be (the short answer - very, very stable), and another lengthier one about free will and not worrying about not having it.
I haven't had time to go through the free will one in detail (and the long list of comments, which will no doubt contain some interesting material) but hope to soon.

Amazing re-writes of history
I have been utterly gobsmacked to read a couple of the "regulars" in comments at Catallaxy in the last few weeks promoting the idea that the Rudd government's ending of the "Pacific Solution" following its election in 2007 was not an election policy.
This highly creative (by which I mean, imagined) meme then gets the occasional comment of support "well, someone should be calling out Rudd as a liar then, when he now says his changes in 2008 were simply putting an elective mandate into effect."
I have seen exactly one person challenge it with anything resembling a reference to evidence - someone saying that they remembered a Kerry O'Brien interview where Rudd said he would close down Nauru.
That is correct. Here is the section of the interview in question, held only a couple of days before the election:
And, as I say, that so few readers at the blog would actually try to correct them.
But then, it is a blog full of AGW conspiracists and deniers.
At least I give credit to a handful there who see the parallels between the last US presidential election and what is happening now. Because it is shaping up that way: a large slab of the Right here is viewing many issues as part of a cultural war of their own desiring. They have positioned themselves as the darlings of the older end of the electorate, and are making little connection with anyone under about 35.
There's still time for Rudd to blow his credibility out of the water, and a lot will depend on revised Treasury figures as to the budget position; but at the moment, I think a Labor win is looking quite on the cards.
Update: I forgot to mention last night that even Tim Blair, who one imagines Catallaxy readers visit regularly, was talking only 4 days ago about how Tony Burke was writing before the 2007 election about how Labor would close down the Pacific island off shore processing centres.
And besides which, when they were closed, there was absolutely no media outrage that it was unexpected.
It was completely expected.

That is correct. Here is the section of the interview in question, held only a couple of days before the election:
KERRY O'BRIEN: On refugee policy, Mr Rudd, there are 82 Sri Lankans and seven Burmese being held on Nauru as we speak, part of Mr Howard's Pacific Solution. If you win on Saturday, how quickly will you move to shut down the Nauru and Manus Island options and where would the detainees go?For a broader context, there is this:
KEVIN RUDD: We haven't taken advice on that. What we have said that for us, we have an appropriate offshore detention facility, though it's part of Australia on Christmas Island. Christmas Island, I understand, has the capacity of some 800 beds. The so-called Pacific Solution has cost the taxpayer hundreds of millions of dollars. Why not use Christmas Island instead? It strikes me as pretty well self-evident.
KERRY O'BRIEN: But how quickly would you move to close down the Manus Island and Nauru option?
KEVIN RUDD: Not privy to the specific contractual and administrative arrangements which were associated with each of those deals...
KERRY O'BRIEN: But I think it's policy. I think Mr Burke your shadow Minister says you will.
KEVIN RUDD: It's policy. We will but your question was how soon.
KERRY O'BRIEN: I think his statement is that you would do it immediately.
KEVIN RUDD: That's true.
KERRY O'BRIEN: And I am asking in terms of your immediate priorities in government, your immediate priorities, will you move as an immediate priority to deal with that?
KEVIN RUDD: At a very early stage. The Pacific Solution is just wrong. It's a waste of taxpayers' money. It's not the right way to in fact handle asylum seekers or others and therefore we think the best way ahead is to use Christmas Island instead. It's a facility which is part of the Commonwealth of Australia. The other thing is this. You think I'm somehow quibbling about this. If you're a responsible alternative government you need to actually look at the advice entirely in its detail on whatever contractual arrangements now exist with those...
I find it inconceivable that adults with an alleged interest in politics such that they spend hours every week commenting at a political blog could have convinced themselves that this history from all of, oh, 6 years ago does not exist.On 24 November 2007, the Australian Labor Party (ALP) won the federal election, defeating the Coalition Government which had been in power for nearly twelve years. Kevin Rudd was sworn in as Australia’s 26th Prime Minister on 3 December 2007. The ALP National Platform, which was formally adopted in April 2007, represented the party’s ‘long-term aspirations for Australia’.[2] In relation to immigration, the ALP ambitiously resolved to implement significant changes for asylum seekers and refugees if elected. Most notably, to end the so-called ‘Pacific Solution’; to give permanent, not temporary, protection to all refugees; to limit the detention of asylum seekers for the purposes of conducting initial health, identity and security checks; to subject the length and conditions of detention to review; to vest management of detention centres with the public sector; to retain the excision of Christmas Island, Cocos Islands and Ashmore Reef; and to create a new Refugee Determination Tribunal.[3] In the area of refugee policy the key themes of the platform were ‘humanity, fairness, integrity and public confidence’.[4]Reflecting on the Government’s first year in power, the then Minister for Immigration and Citizenship, Chris Evans, noted ‘Labor was elected on a platform of change’.[5] One of the first things the newly elected Labor Government did upon taking office was to stop processing asylum claims in the small Pacific Island State of Nauru—which the then Minister described as a ‘shameful and wasteful chapter in Australia’s immigration history’.[6] However, in retaining the former Coalition Government’s excision policy (which removes the right of asylum seekers to apply for a visa) and use of its purpose built immigration reception and processing centre on Christmas Island, the Government attracted criticism from refugee advocacy groups and academics alike—Adjunct Professor Michael White being of the view that Labor’s new approach ‘did not fundamentally alter Australia’s previous immigration policy and many features of the Pacific Solution remained’.[7]

Get your act together, ABC
I feel like a general bleat, even though I have said it before: the ABC News website is just awful design for a news site, with its minimal number of "headline" stories and the need to "drill down" to find a more extensive list of stories.
This is rubbish for a well funded news organisation.
As far as I am concerned, a news website should maximise on the front page the number of direct links to stories: the layout of The Guardian runs rings around the ABC site, with its multiple links to further detail on major stories, as do the Fairfax sites. I would even say that The Australian (God forbid) is substantially better than the ABC layout (if you ignore the paywalling, at least.)
BBC News has a touch of the ABC's about it, but is still more information heavy on its front page than the latter.
I can't be the only person who finds this ABC News web design crappy, surely?

Yet another article on bloated Hollywood
Steven Spielberg Hollywood imploding: How he predicted a disastrous summer at the box office. - Slate Magazine
A balance article here that puts a bit of perspective on the current failed big budget movies of this American summer:
A balance article here that puts a bit of perspective on the current failed big budget movies of this American summer:
In an interview with New York magazine critic David Edelstein, producer Lynda Obst also pins the current trend toward gigantism on the increased importance of the foreign market, coupled with a collapse in DVD sales, which once provided a safety net for midrange pictures that didn't pan out. Obst's new book Sleepless in Hollywood features a list of movies she's certain wouldn't get made today, including such Oscar winners as Moonstruck and Forrest Gump.Update: by the way, both Moonstruck and Forrest Gump were fantastically over-rated films, in my opinion. It's unfortunate that they are given as examples of films not being made now.
It’s not the first time Hollywood has succumbed to the allure of bloat. Film historian David Bordwell points to the expensive musicals that followed in the wake of The Sound of Music. “The industry had pinned its hopes on films like Dr. Dolittle, Thoroughly Modern Millie, Star!, and Darling Lili,” Bordwell emails. “They were the ‘tent-poles’ of their time, and they mostly failed. There were also the super-sized comedy spoofs like It’s a Mad, Mad, Mad, Mad World, The Great Race, and A Funny Thing Happened on the Way to the Forum, all of which remind me a bit of The Lone Ranger’s elephantiasis.” Still, Bordwell adds, “the flopolas here weren’t happening in such a compressed time span, as we’re finding this summer.”
Lose weight, become a jerk
The post heading is inspired by, and describes, the recent history of Joe Hockey. Here he is quoted today:
Hockey seems to believe that Treasury wants to bend over backwards to accommodate just one side of politics; so much so that they will fudge figures for Labor. That is, surely, an enormous slur on public servants, and if Hockey (if Treasurer) oversees a clean out of Treasury, is it going to be staffed with Right wing twits who support this "Treasury is too politicised" guff? Why not put Judith Sloan in and be done with?
But shadow treasurer Joe Hockey told The Australian Financial Review the process was becoming a sham and the Coalition would no longer respect the figures in either the economic statement or PEFO.The problem, as I understand it, is to do with revenue. The Coalition will promise to "fix" it by big spending cuts. In fact, the lower dollar will soon start to help the economy anyway.
Previously, he promised to release detailed costings of Coalition policies only when PEFO was released. Now, he said, that pledge may no longer hold.
“We’re not going to cop the Treasury being bullied by the government into producing PEFO numbers that are closely aligned to the government’s,” he said.
“If PEFO looms the same as the economic statement, then PEFO won’t be worth the paper its written on.”

Gravity 2
I put up the first Gravity trailer, and now the second one is also making a big splash around the Web. It looks fantastic, especially if you watch it full screen:
The only thing I don't get: if the movie is about two astronauts who get marooned in space in the first act, how does it make their plight interesting for the next two acts?

No inflation woes, still
Inflation figures expose carbon scare campaign
Tim Colebatch feels vindicated:
Some wrecking ball that was! Australia's first year with a carbon tax has ended with inflation so low that it was only the carbon tax that kept inflation from falling out of the Reserve Bank's target range.
The Bureau of Statistics reports that in the year to June, consumer prices rose 2.4 per cent on the raw data, 2.3 per cent after seasonal adjustment, and 2.2 per cent on the trimmed mean measure, which strips out the biggest price rises and falls to define underlying inflation.What were other right wing figures saying about the carbon "tax" and inflation?
If you take out the September quarter - as the next set of inflation figures will - then inflation over the nine months to June was running at an annualised rate of just 1.3 per cent. Underlying inflation is tracking at 2 per cent.
And while the dollar has fallen in the past three months and petrol prices have jumped, it's odds-on that the next measure of inflation will start with a 1.
That is low inflation by any measure. It shows the Coalition's scare campaign against the carbon tax was just a scare campaign.
Well, a retiring RBA board member and businessman at the start of 2012 was worried, and told The Australian (who else):
... Mr Kraehe said the introduction of the carbon tax, rising wages in the resource sector and a weaker Australian dollar could all combine to put upward pressure on inflation in the year ahead. While interest rates were currently "ideally positioned" at 4.25 per cent, Mr Kraehe said inflation was set to become "more of an issue".And look, guess which paper (hint: after "The", it starts with an "A") ran this opinion piece from the anonymous (but leading independent economist, apparently) "Henry Thornton":
A tax of $23 a tonne for the CO2 emissions of Australia's 500 greatest polluters will severely handicap Australia's most productive industries. Production, jobs and emissions will be shifted offshore to countries and competitor producers less concerned than the Australian government about the supposed costs of greenhouse gas emissions.Stagflation! Well who does that remind me of? Yes, he was having a gripe in October last year:
This is action guaranteed to reduce the productivity of Australian industry, increasing the strength of the stagflationary forces already evident.
Government (and Treasury?) would like us to believe that the carbon tax is on track, the modelling all fine, and concerns about utility prices overblown.And here he is, complaining that the ABS was not going to try to differentiate the contribution of the carbon price to inflation.
When overall inflation is so well in the range, what would be the point?

Something you are unlikely to see anywhere else on the Internet
After just reading again about the way biographers have spent much effort psychoanalysing CS Lewis from afar, it amuses me greatly to think how much could be imagined into blog posts in the age of the internet, especially when apps let something like this be easily made:
Yet more CS Lewis biography
Mere C. S. Lewis | TLS
There are still biographies being written about CS Lewis, and this review of two of them is not a bad read, but it didn't contain much in the way of information that I hadn't read elsewhere. Except, perhaps, for this minor anecdote:
There are still biographies being written about CS Lewis, and this review of two of them is not a bad read, but it didn't contain much in the way of information that I hadn't read elsewhere. Except, perhaps, for this minor anecdote:
In his biography, McGrath is candid about the eccentric and less edifying side of his subject’s life. Lewis was personally shabby and unkempt, and he let his house get into an unhealthily filthy state. He refused to learn to type or drive a car. He smoked and drank heavily: Tolkien was amused to hear a reference to “the ascetic Mr Lewis” on a day when he had seen him down three pints of beer at lunchtime.
Neat
Hunt for alien spacecraft begins, as planet-spotting scientist Geoff Marcy gets funding
So, the Templeton Foundation, much criticised by some prominent atheist scientist figures (well, Sean Carroll comes to mind at least) for promoting "woo", has given some funding for a search to look for signs of alien civilisations (spaceships, Dyson spheres, or lasers).
It's not clear what should be looked for yet, but that's part of the fun:

It's not clear what should be looked for yet, but that's part of the fun:
Marcy hopes that hiding within it will be hints about intelligent life abroad. What if, say, the dimming of a star that Kepler observes is caused by something even more fanciful than the passage of extrasolar planets? Something synthetic, perhaps? Marcy admits that even he's not certain what he's looking for.
"I do know that if I saw a star that winked out, then at some point it winked back on again, then winked out for a long, long time and then blinked on again, that that would be so weird," he says. "Obviously that wouldn't constitute the detection of an advanced civilisation yet, but it would at least alert us that follow-up observations are warranted."
Such an irregular pattern might signal the leisurely and unpredictable passage of massive spacecraft in front of the star. But, perhaps more likely, it might indicate the presence of a Dyson sphere, a mainstay of science fiction first proposed by physicist Freeman Dyson in 1960.
As for the laser search:
The rest of the $200,000 grant is buying Marcy time on the Keck Observatory in Hawaii, the largest telescope in the world, to search for - what else? - a galactic laser internet.Research well worth doing, I reckon.
While the movie Contact, based on Carl Sagan's book of the same name, popularised the idea of aliens dozens of light-years away picking up an old telecast of the 1936 Berlin Olympics that was unintentionally transmitted into space, our civilisation has become quieter to any outside observers in recent decades. As our civilisation makes the jump from analog to digital, communication is increasingly carried by fibre-optic cables and relatively weak mobile phone repeaters rather than powerful broadcast transmitters. Rather than spilling out messy radio transmissions, Marcy posits that alien civilisations would use something much more precise and efficient than radio waves to stay connected, and lasers fit the bill. At the Keck Observatory, he hopes to spy an errant beam flashing from a distant star system, an observation that would be strikingly obvious on a spectrum.
Say something stupid, get endorsed on Catallaxy
Bernard Keane from Crikey made this statement about plain packaging cigarettes:
Anyone who had read anything about the plain packaging argument knows that the effect of getting less children to start smoking was always believed by many to be the main way it would work. Here's Harry Clarke in 2012:
But all of that is not good enough for Sinclair Davidson, who thinks evidence should be in by now and that the lack of evidence on the number of smokers means he can already declare the "policy is a dog." The policy has been fully in effect for about 7 months.
Talk about taking glib and pathetically poorly informed criticism to new heights.
One of the highest profile public health industry lobbyists, Professor Mike Daube, yesterday claimed “the primary focus for plain packaging was always to reduce smoking among children, but it is a real bonus that it has clearly had an impact on smokers”. That’s rather different to what Daube said when plain packaging was first announced, when he claimed “we know from research that it will have a significant impact on children and adults”. Is Daube readying for when we see that plain packaging hasn’t affected tobacco sales?Actually, Bernard, it is not "rather different" at all. You can say that something will have a significant impact on both A & B, while believing that the primary effect will be on A. To say that the impact on B is "a bonus" is hardly controversial rhetoric.
Anyone who had read anything about the plain packaging argument knows that the effect of getting less children to start smoking was always believed by many to be the main way it would work. Here's Harry Clarke in 2012:
Well, I think the main target is youth. Young people, it's claimed, are seduced by the attractive packaging and the brand names that are associated with cigarettes. I guess for confirmed smokers it won't make so much difference, but certainly for youth, it's well recognised that branding does have an impact on purchasing choices. We've currently done pretty well in Australia in reducing smoking rates among young people, but this is really trying to clinch the deal and to reduce the initiation of smoking among young people as much as possible.
But all of that is not good enough for Sinclair Davidson, who thinks evidence should be in by now and that the lack of evidence on the number of smokers means he can already declare the "policy is a dog." The policy has been fully in effect for about 7 months.
Talk about taking glib and pathetically poorly informed criticism to new heights.
Guess where...
It's been warm up north - like 32 degree warm, and this very pleasant looking beach on a body of fresh water is: Loch Morlich in Scotland.

$40 a tonne?
Origin Energy chief says low carbon price will encourage future investment in coal-powered plants
I saw this interview with Grant King on Sunday, talking about how you would actually need a carbon price of about $40 a tonne to make developing new coal fired power stations unattractive.
This sort of figure has been bandied about before, and given the state of the European ETS price, it makes you wonder why economists like John Quiggin seem so relatively relaxed about Australia joining up to that scheme.
I really don't understand.
But, on the other hand, I still am yet to hear any economist in the land argue that the Coalition direct action plan is an efficient way to do what it claims to want to achieve.

Big movie failures
‘Turbo’ and ‘R.I.P.D.’ Open to Disappointing Results - NYTimes.com
From the report:
I actually want to see The Lone Ranger - some reviewers have liked it, and I am very fond of the Pirates of the Carribean movies. Even the third one has grown on me by re-watching it on DVD.
What you have to do is what the whole series in quick succession - say, over a week. The entire arc of the story makes much more sense that way, and you actually notice jokes in the last movie (for example) that depend on remembering incidents and characters from the first movie.
On a sailing related note, I also finally caught up with Master and Commander on DVD. As with Pirates of the Caribbean, I am continually impressed with how utterly realistic modern movie technology can make sailing ship battles and storms appear. But the movie itself seemed more interested in just being an earnest portrayal of life at sea in the British Navy in 1805, rather than having a really compelling story or characters. Maybe the books are better, but the movie felt a little hollow at heart. I don't really see that it was worth 10 Oscar nominations.
From the report:
With extremely weak domestic ticket sales over the weekend for “R.I.P.D.” and “Turbo,” Hollywood has now sustained six big-budget duds since May 1, the start of the film industry’s high-stakes summer season. The other failing movies have been “After Earth,” “White House Down,” “Pacific Rim” and “The Lone Ranger.”The main thing disappointing about that list is that there are no Marvel superhero movies included. I'm desperately sick of all the money being sunk into them.

Arthur noted
I've only caught the last 20 minutes of Q&A tonight, but I have to say again that Arthur Sinodinos is one of the few on the Coalition side of politics at the moment who appears to be a decent, relatively straight talking politician. He and Malcolm Turnbull are about the only two who don't set my teeth on edge.
As for the rest: Abbott needs to chuck it in for being promoted above competency; Julie Bishop is, I am sure, actually a robot; Christopher Pyne can't "handle" the truth (or rather, he can't deliver it); Joe Hockey looks means and cranky since he lost weight and has to puff himself up with indignation and hyperbole for the cameras regularly; Andrew Robb does not look quite engaged, despite his medication; Scott Morrison is an arrogant motor mouth; Greg Hunt has to sell his principles and learning and endorse a rubbish climate change plan; Sophie Mirabella has a reputation for appalling bitchiness in Parliament; Bronwyn Bishop is still floating around and endorsing anti-science; Eric Abetz has a touch of the "not quite human" like Julie B; George Brandis is (I believe) well hated by many Liberal Party members for being annoying and arrogant.
It's a great line up....

Free will on the brain
Is free will a scientific problem?
The article refers to a book by Peter Tse, which argues that the brain's ability to re-wire itself quickly actually means that free will is real. From another link:
The article refers to a book by Peter Tse, which argues that the brain's ability to re-wire itself quickly actually means that free will is real. From another link:
Tse draws on exciting recent neuroscientific data concerning how informational causation is realized in physical causation at the level of NMDA receptors, synapses, dendrites, neurons, and neuronal circuits. He argues that a particular kind of strong free will and “downward” mental causation are realized in rapid synaptic plasticity. Recent neurophysiological breakthroughs reveal that neurons function as criterial assessors of their inputs, which then change the criteria that will make other neurons fire in the future. Such informational causation cannot change the physical basis of information realized in the present, but it can change the physical basis of information that may be realized in the immediate future. This gets around the standard argument against free will centered on the impossibility of self-causation. Tse explores the ways that mental causation and qualia might be realized in this kind of neuronal and associated information-processing architecture, and considers the psychological and philosophical implications of having such an architecture realized in our brains.My brain is not sure what to think of this yet. Rewiring is currently in progress....
Wandering black holes
A Captured Runaway Black Hole in NGC 1277?
Here's the abstract from the above paper at arXiv:
Here's the abstract from the above paper at arXiv:
Recent results indicate that the compact lenticular galaxy NGC 1277 in the Perseus Cluster contains a black hole of approximately 10 billion solar masses. This far exceeds the expected mass of the central black hole in a galaxy of the modest dimensions of NGC 1277. We suggest that this giant black hole was ejected from the nearby giant galaxy NGC 1275 and subsequently captured by NGC 1277. The ejection was the result of gravitational radiation recoil when two large black holes merged following the merger of two giant ellipticals that helped to form NGC 1275. The black hole wandered in the cluster core until it was captured in a close encounter with NGC 1277. The migration of black holes in clusters may be a common occurrence.You wouldn't want a cluster of black holes passing near your solar system, I assume.

Be appalled...be very appalled
It took me quite a bit of Googling to track down this story which was recently in the Sydney Morning Herald Good Weekend magazine "2 of Us" section. But here it is, an almost comically appalling story of one woman and the professional biker thug she loves.
It features the opening line:
It features the opening line:
I was a nurse before I met Caesar. If I hadn't been, I wouldn't have been able to get the bullets out of his back years later.
and goes on to explain how she is still with amazingly unattractive (both morally and physically: have a look at the photo) outlaw biker she met in 1978.
The best line from "Caesar's" section (where he gets to tell his side of the story):
I sat there one day and was thinking about her and everything she did for me and I thought, "She really is like the ultimate woman." So I started calling her "Woman", and that's what I've done for 34 years. If I say "Donna", she comes in with her head down looking like she's in trouble.
I see that she has written a couple of books about their time in "outlaw culture", and this piece is probably really just a bit of self promotion. That means I probably shouldn't be mentioning them either - I hate it when the media gives de facto celebrity status to criminals who write a book along the lines of "look at me - look at how bad I've been. Contribute to my retirement fund by buying this."
Still, this example of the genre really was noteworthy. Just don't buy their books!
