Crossing over

Neutrons escaping to a parallel world?

From the link:

Theoretical physicists Zurab Berezhiani and Fabrizio Nesti from the University of l'Aquila, Italy, reanalysed the experimental data obtained by the research group of Anatoly Serebrov at the Institut Laue-Langevin, France. It showed that the loss rate of very slow free neutrons appeared to depend on the direction and strength of the magnetic field applied. This anomaly could not be explained by known physics.

Berezhiani believes it could be interpreted in the light of a hypothetical parallel world consisting of mirror particles. Each neutron would have the ability to transition into its invisible mirror twin, and back, oscillating from one world to the other. The probability of such a transition happening was predicted to be sensitive to the presence of magnetic fields, and could therefore be detected experimentally.

I have a soft spot for any physics talking about particles having a mirror particle in a parallel universe.  Seems a good way to get heaven, no?

The full paper is available for free here for some reason, although it's only worth it for the opening and end paragraphs.  Here's the last paragraph:

The biggest worry is the potential bloatware

Review: Microsoft Surface straddles divide

Everyone who held the new Microsoft tablet device seems to have liked it, and the thin, go everywhere keyboard does sound very good.

My biggest worry is whether Microsoft can keep down the bloatware-ish nature of their software, including the new Windows, to make a tablet not fill up so quick.

My Gina Theory

Why does Gina Rinehart like to buy into media companies?

I have a pet theory about Fairfax, at least.  It might be as revenge for a far from complimentary profile that ran earlier this year.

Amongst other things I probably read at the time but had forgotten (I don't pay much attention to billionaires, as it happens):

*  she has a reputation for penny-pinching. One former employee tells of being instructed to phone suppliers of office equipment to haggle over even the smallest bills. Another says he got the impression that Rinehart personally scrutinised staff expenses claims. "She had a thing in the back of her mind that everybody, and I mean everybody, was out to do her down, to take a dollar off her," he says. "She trusted nobody and assumed the worst of everybody."

* [Talking of her fractured relationship with some of her children] "I'm not a psychologist, but I'm a close observer of the family," Singleton says. "It's because the business comes first. Being a parent is secondary. It's just, 'Where do they fit into the dynasty? Are they iron or are they coal or are they uranium?' If they don't fit into the company, there's no role for them."

*  "School was just a nasty interlude to put up with," he said. "Then she tried a year doing economics at Sydney University but she found out it was basically communist ..."Rinehart told Robert Duffield, author of the Hancock biography Rogue Bull, that the university taught "the wrong things". Duffield noted that she parroted Hancock's political views, "mastering all his stock tracts, phrase by phrase". Singleton was aware of this, too: "I mean, a conversation with Gina was a conversation with Lang. They both had the same fanaticism ... If Lang paused, Gina could finish the sentence."

* Rinehart's next husband was an American tax attorney almost four decades her senior. Gina was 28 when the couple wed in Las Vegas in 1983. Frank Rinehart was 65. [This was, however, a happy marriage.]

* Newspapers reported in 1997 that Rinehart had reached a confidential out-of-court settlement with her former live-in security guard, Bob Thompson, who had filed a sexual harassment complaint against her. In a long article in Woman's Day, Thompson said Rinehart became infatuated with him and wanted to marry him, despite his being engaged to someone else. "I told her over and over I wasn't interested," he said, but "she wouldn't take no for an answer". Thompson made plain that in some ways he felt sorry for Rinehart: "She's just incredibly lonely and isolated."

Singleton tells me Rinehart has no interests besides mining. "There is no social life," he says. "It's just work."

There is much more in the article.

It really is not a picture of a likeable person.   If anything, it reads a bit like a real life version of Citizen Kane, with unhappy adult children thrown into the mix.   In terms of political views it sounds like they were formed while sitting on her Dad's lap and haven't moved on from there.

I see Alan Kohler, who I assume has met a fair few people who have met Gina, calls her today "Australia's strangest rich person".

I know nothing of how much personal responsibility she can take for growing her father's fortune, but her promotion of climate change skepticism by sponsoring Monckton out to Australia (and welcoming Ian Plimer to talk to visiting foreigners) does not speak well for her general judgement (to put it mildly.)   If she genuinely wanted to know about the science, she could fly in the top scientists from around the world for her own private briefing.  Instead, the voice of the loner contrarian appeals to her personality, I suppose.

Sure, her works mean a lot of employment and income for the country, but especially that she was the heiress to her father's ideas and fortunes, you can't give her high marks for exactly being "self made" either. 

Some billionaires genuinely should be admired for their extensive philanthropy for the good of humankind.   Bill Gates in particular seems to combine a happy family with extensive good works, many benefiting the poorest of the world.   It would appear that Gina does not spend much proportion of her fortune in any similar way.

So is Gina buying her way into control of Fairfax an act of revenge for (perhaps amongst other things) what might have been a hurtful profile?   Making it a real vanity project to slavishly promote her single minded (and, in some cases, rather simple minded) views would no doubt hurt the papers and kill them off completely.   

Who knows?   But it's as good a pet theory as any.

Update:    I don't know if anyone else using Blogger has found this, but ever since their new editing layout for posts came out, I have a hell of a lot of trouble getting breaks between paragraphs right.  What looks right in the "compose" window often isn't when you post, and then you can have a lot of trouble working out which bit of HTML is causing the problem.  This did not used to be the case.   Annoying.

Insightful

The IVF lottery of joy and sorrow

This article from The Age on the weekend was well worth reading.   It tells the story of the poor success rate of IVF for over 40 year old women, yet the fact that it occasionally works on women even over 45 means that it keeps being tried:

In the assisted reproduction business, those who get older women pregnant achieve holy grail status. Which means there is great pressure on them to put over-40s women through as many cycles as possible to get the success rates up.

As it stands there is no limit to how many IVF cycles a woman can undergo in Australia, and hence no shortage of doctors willing to perform the procedure.

Yet what has really bothered me is that, as with so many of my girlfriends on IVF, no one seemed to be monitoring Louisa's mental health. And Blind Freddy could see she was not well in that department. At all.

''Counselling? What use was that?'' Louisa told me. ''I wasn't going to tell them anything was wrong in case they rejected me for treatment. I wasn't going to admit I cry all day, every day. Of course I was depressed. I wanted a baby and couldn't have one. I was there for them to give me hope, not point out the obvious.''

I realise that doctors must feel in a bit of bind in that they can't advise the patient that there is no hope whatsoever, and if it works it's the "cure" (I suppose) to their depression; but on the other hand, the reality is that the for great majority of patients above a certain age, it is only going to protract the disappointment and delay the process of getting over the inevitable accommodation to not being able to have your own baby.

Technical issues

I'm feeling vaguely technically competent after working out how to run Linux on an old laptop from a usb drive.  I used Puppy Linux, and it seems to be working fine, except upgrading the browser and other software that comes with it seems to be the issue that requires some more detailed knowledge of Linux.

[Well, actually, there is still an issue I don't understand.  I tried Linux because something in the old XP laptop when running Firefox would often cause the hard drive to start into continual activity, the fan would go into overdrive and everything would become laggy.  I could never work out what process was causing this - it seemed to be Firefox itself most of the time, but I quite like using it compared to Chrome.  So I thought, this may all be tied up with XP somehow.  But when running Linux from a USB, the hard drive light goes on and just stays on.  I can't really hear the hard drive working much, but I like hard drives to feel relaxed, so I am still disappointed that this happens.  The browser itself doesn't slow down, though.] 

Anyway, I had been wondering for a while what it was inside the iPad (or smartphone) that lets it know which way is up.  The answer is explained here:

A very sad loss

ABC radio personality Alan Saunders dies

What sad news.  Alan Saunders has done a great job for years and years at Radio National, covering everything from design and architecture, culinary pursuits, to philosophy, and probably some other topics I have now forgotten about.  His style was relaxed and knowledgeable, but he was engaging and accessible because you never felt he was assuming too much knowledge of his audience.  And he just always seemed a self-effacing, nice man.  I often forgot to deliberately tune in to his shows, but if I caught one by accident, I was nearly always glad that I had heard it.

I see dumb people

Rabett Run: Carrick finds a mirror

Eli Rabbet tells us how Bishop Hill and Watts Up With That note with disapproval some of the vile death threat emails sent to University of East Anglia (and Phil Jones in particular, it would seem) which have recently turned up via FOI.

Anthony Watts in his post about the emails  goes on to claim that in his former world of being a TV and radio weatherman, he's seen this all before.

Frankly, I do not believe him.   Upset that your weekend bar-b-q got rained out?   Writing a death threat to the weatherman is one of the less common reactions around, I'm sure.

Watts also goes on to tell the tragic tale of how he was upset with a David Appell reference to his dead mother (a completely over the top reaction to a reference to a post title that says more about Watts having "mother issues" if you ask me.)   Watts is not a mature individual in the way he reacts to criticism. He has just about the thinnest skin around the blogosphere.  

But the funnier thing is that WUWT comments on the story are chock full of people saying that they are sure these abusive emails are a "false flag" operation.

Amazing self delusion.

Cardinal Marx urges Europe to move ‘beyond capitalism’ | CatholicHerald.co.uk

Cardinal Reinhard Marx has called for a “social market economy” in the wake of the fiscal crisis that has gripped much of Europe over the past year.

In a talk delivered at Georgetown University in Washington, Cardinal Marx, the Archbishop of Munich and Freising, said the economy needed to move “beyond capitalism” in order to be more fair.

He added that he was not calling for the abolition of capitalism, saying that capitalism was “an element” in the social market economy he has in mind. But Cardinal Marx suggested that it was the practice of “financial capitalism” in the era since the tearing down of the Iron Curtain that had brought Europe to its crisis point today....


Berkley Centre director Thomas Banchoff noted that some in the United States interpret the Catholic social teaching principle of subsidiarity – which holds that decisions or actions should not be made on a higher level when a lower level of competence would suffice – as meaning “keep the government out of it”.

Cardinal Marx replied: “The state is not a bad thing, as Aristotle told his disciples”, nor is the state “unfriendly”. Without the state, he said, “man does not come to the fullest possible life”, adding: “You cannot navigate the common good only with the assistance of families. It is not possible.”

The cardinal travelled from Washington to Chicago, where he was to lead a May 31-June 1 symposium called “Toward a Moral Economy”.

Seems an odd result

Top risk of stroke for normal-weight adults: Getting under 6 hours of sleep

The participants had no history of stroke, transient ischemic attack, stroke symptoms or high risk for OSA at the start of the study, being presented today at SLEEP 2012. Researchers from the University of Alabama at Birmingham recorded the first stroke symptoms, along with demographic information, stroke risk factors, depression symptoms and various health behaviors.

After adjusting for body-mass index (BMI), they found a strong association with daily sleep periods of less than six hours and a greater incidence of stroke symptoms for middle-age to older adults, even beyond other risk factors. The study found no association between short sleep periods and stroke symptoms among overweight and obese participants.

"In employed middle-aged to older adults, relatively free of major risk factors for stroke such as obesity and sleep-disordered breathing, short sleep duration may exact its own negative influence on stroke development," said lead author Megan Ruiter, PhD. "We speculate that short sleep duration is a precursor to other traditional stroke risk factors, and once these traditional stroke risk factors are present, then perhaps they become stronger risk factors than sleep duration alone."

A three movie weekend

It's been a good weekend in Brisbane to be inside watching movies on TV, and I'm inspired to give mini reviews of a strange trio of viewing:

*  AI:  Artificial Intelligence - this is the first time I have seen it since at the cinema in  2001, where I distinctly remember a woman in the smallish audience saying loudly at the end "well, that was weird".   And let's face it, it is an odd movie:  certainly the most expensive and melancholic story about future robots ever made.  But it's a really remarkable looking film, and as with Minority Report, Spielberg manages a creepy vision of a half dystopian future that sticks in the mind for days after seeing it.   The acting is also really fine, I think, and the direction extremely pleasing in the way Spielberg routinely is.

Watching it this time, it occurred to me that it is pretty much a realisation of what I read was George Lucas' original idea for Star Wars - to tell a story from the robots' point of view.   While the film is not thematically novel (I think its most similar predecessor is actually Astroboy), it is the best treatment of the existential crisis  that embodied AI itself may suffer that has ever been made. 

Many people feel sure that the ending was Spielberg's idea tacked on to a story which probably originally ended with a robot suicide; certainly I can understand why people suspect this, as it has his familiar theme of "family" re-union.   But he has stated in interviews that the parts which people suspect are his (and he must be referring to the last 10 or 15 minutes) were always in the Kubrick treatment which he turned into a script.   Until someone else has seen Kubrick's treatment, I think we should just take his word for it, and so some of the criticisms about the movie are, in a sense, made on a false presumption.   In any event, I don't think the ending is overly sentimental; or at least, it's certainly a bitter-sweet type of sentimentality.  In fact, it is ambiguous as to exactly has happened with David - I have just read somewhere that John Williams says he dies at the end, and if the whole "resurrection" was designed to let him shut down in peace, that does make sense.  Yet the voice over is ambiguous on the point.  I guess ambiguity does not always hold back a science fiction film from greatness, but it tends not to help.   

Which leads me to the the major point that the movie can be faulted for - the lack of clarity about the spindly creatures at the end.  They are, everyone now accepts, meant to be advanced "robots"; but the cues by which one is meant to definitely understand that on first viewing are far from as clear as they should be.  I don't even like their design, and the quasi weightlessness they exhibit which also adds to the confusion over whether they are meant to be "otherworldly" or not.  There was, after all, one large spindly looking alien spied in the mists of the mother ship at the end of Close Encounters, and memory of that must surely have been in many viewers' minds.

But, having understood them as advanced, evolved "mechas", their apparent concern for David does raise a philosophical question of interest for transhumanism:    do we really have a solid basis for assuming that love and altruism would be the outcome of super-advanced AI?  Or would future intelligence, losing its connection to flesh and blood emotionalism, appear to us as just ruthless and cold?   Frank Tipler argued that game theory was reason to believe it would be altruistic, but I am not sure how convinced other futurists are about this.

In any event, despite its flaws, it is a highly original and interesting film, and more praise to Spielberg for even attempting such "difficult" material and nearly pulling it off.

* Lost Horizon (1973 version):    Oh Good Lord - I knew this film had a horrible reputation, but I attempted yesterday (mostly successfully) to plough through and check it out for myself.  (My kids kept walking in and out of the room saying "you said this was terrible, why are you still watching it?")

It is spectacularly bad in every conceivable respect - a cast completely unsuited to a quasi-romantic musical; horrendous, cringe-inducing acting by nearly everyone (Michael York and Sally Kellerman in particular); a bunch of truly terrible songs by Burt Bacharach and Hal David with the only "memorable" one (The World is a Circle) working as an unpleasant ear worm that just won't stop; the rest of the music (melodramatic strings) sounding like it escaped from a 1940's film; an awful script; even sets which look cheap and tacky.

It's long; it's awful; it's a wonder anyone who appeared in it ever worked in film again.  Comes close to being recommended as "so bad its good", but like Ayn Rand, its length mitigates against that recommendation.

*Sunshine (2007):    I like space faring science fiction, generally, and while this one starts out in a sort of promising fashion, by the end it is a complete and utter mess.

The fault, I think, must be put down to the director Danny Boyle.   I just can't believe that an editor alone could be responsible for such a hash made in the last 30 minutes or so.  Sorry to keep bringing up Spielberg again, but Boyle here is like the anti-Spielberg in terms of making a film in which the action sequences become narratively nearly completely opaque.

As for science, we'll not dwell on the improbabilities of attempting to re-start the sun with all the fissile material on Earth.   That's just an improbability to accept, and without which there is no movie.  But it is remarkable that for a script which showed some vague concern for having a plausible looking massive spaceship, they get some science very wrong.  The super-fast freeze of a body in the vacuum of space is the main example, but the whole "everything that gets out of shield shadow instantly explodes in sparks" shtick was not very realistic either.  

I am really surprised that the movie scores 75% on Rottentomatoes, and am inclined, even without worrying about the science, to go along with this (spoiler containing) summary:

The crew seemed like a bunch of college dorm dwellers thrown into a really bad camping trip.  The crew seemed… unprofessional.  And far less trained and together than you would have expected.  They also make sure one, and only one, person can do any job on the ship.  For a crew replicating a previous failed mission, I might think they’d want to have multiple redundancies. And the worst part: I thought this was just an sci-fi thriller.  No, it’s a slasher film.  The director uses some stupid tricks (e.g., 1 to 2 frame still picture inserts to create a sense of foreboding) to goose the story, and the final bit with a psycho, 3rd degree burned astronaut from the first failed mission stalking the crew and slashing/stabbing them was just too much.  

I'm very glad I didn't spend money to see it.

Much warmer

US spring warming off the charts

The United States, excluding Alaska, Hawaii and overseas territories, had an average temperature of 57.1 degrees Fahrenheit (13.9 Celsius) from March through May, 5.2 degrees (2.9 Celsius) above the average from 1901 to 2000, the data showed.

"Spring 2012 marked the largest temperature departure from average of any season on record for the contiguous United States," the National Oceanic and Atmospheric Administration said in a statement.

This year's spring was up 2.0 degrees (1.1 Celsius) from the previous warmest spring in the United States which was recorded in 1910, the agency said.

In other news from Physorg, a study suggests that increased CO2 may make it much easier for wide varieties of rice (and other food crops) to exchange genes with farmed crops, which is not a good thing for agriculture.

A great writer departs

At his best, Bradbury was a fantastically gifted writer, although I think his style was probably best shown in short stories rather than novels.  That said, I hold "Something Wicked This Way Comes" in very high regard.

Increased realism

Indigenous 'solutions' just disempower us further - The Drum Opinion (Australian Broadcasting Corporation)

I think it says a lot about public attitudes towards the old, left wing, arguments about aboriginal issues that this article run at the ABC Drum website by an aboriginal activist bemoaning the lack of "empowerment" (amongst other platitudes we've heard many times before) being at the core of aboriginal problems in the Northern Territory is met (for the most part) with strong cynicism in the comments.

Fortunately, I think it is fair to say that the Labor Party is just not as captured by this rhetoric as it used to be.  But of course, they remain the party most likely to be hampered somewhat by internal conflict over how much weight to give to ideology to the detriment of outcomes.

Walter Shaw might also be impliedly giving permission for politicians to drop something that I am sure many people find annoyingly political correct:

Politicians and bureaucrats love to open speeches with: "I would like to pay respect to the traditional owners of the land in which we are meeting here today, both past and present."

But these are just words, and they are tokenistic words at that. They do not reflect the real actions of government. The 'present' they refer to is no different to the past.

It seems to me that many people would welcome a politician who at least modified the policy as to when this should be said to something like this:  "If I know a local aboriginal community leader of some note is present, I'll say it.  But if I am addressing general group of people, and the function has no connection whatsoever with issues of aboriginality or entitlement to land, I'm not going to continue mouthing a tokenistic formula of no import to the occasion."

Crazy Mel

Heaven and Mel review: Joe Eszterhas's e-book makes the anti-Semitic star sound worse than ever.

Slate looks at a whole book Joe Eszterhas has written about the breakdown of his working relationship with Gibson, which was recently detailed when he (Joe) released a recording of Mel going berserk about why he hadn't finished a movie script yet.  

Apart from some further details about how dangerous Gibson sounds when he is upset (Eszterhas says he has a "pornographic snuff film" that plays inside his head), here's one novel theory that Mel's Dad apparently believes:

“Did you know that Cardinal Ottaviani sat on Pope John Paul I’s face and suffocated him so they could get the Pope they wanted, Pope John Paul II?” the elder Gibson asks Ezsterhas during a visit to a church built with the profits from The Passion.

I wonder if Mel believes that too...

Have my doubts

Science fiction review: Kim Stanley Robinson’s 2312. - Slate Magazine

Go to the link for a gushing review of a new book by a pretty well known science fiction writer.  Personally, I didn't find the first novel in his Mars trilogy to be all that great, although there are parts of it which have stuck in my memory.  I didn't go on to try the next two books.

The review gives enough plot details to make me think the new book suffers at least one of the problems I had with the Mars novel - he seems wildly optimist about the speed of technological change in a way that just feels rather improbable.   It always seems safer to me for science fiction writers to not be so specific about their future chronology, and leave the reader guessing a bit as to how far in the future we are talking.
