Why Australia is slow to go nuclear

Going fission

Here's a long article in The Age looking at why Australia is very, very slow to consider nuclear seriously. I didn't know this:
A poll conducted this year by the Uranium Information Centre found the 40 to 55 years age group most trenchantly opposed to nuclear power.
So, it's my own demographic which is the stupidest. How encouraging.

Nice TV

Just a quick note to observe that the 3 part nature documentary series "Ganges", which started last night on the ABC, was very spectacular. I see that it has taken a couple of years to make it to screen here, which is a pity.

I know this is a bit of silly prejudice, but I am always kind of surprised when India shows up on documentaries as having a lot of open space and natural beauty. You get so much concentration on the crowded cities on TV, you kind of expect the whole country to look like one giant stretch of humanity from end to end.

Sunday night ABC nature documentaries have become a family favourite at my house.

A new type of controversy at the LHC

Physicist working at CERN arrested : Nature News

This news broke last week, but I wasn't sure if the guy arrested was working on the LHC or not. Seems he was:
He is believed to be a postdoc at the Swiss Federal Institute of Technology in Lausanne (EPFL) who, since 2003, has been performing data analysis on one of four major experiments at the Large Hadron Collider (LHC), the world's most powerful particle accelerator.

French antiterrorism police arrested the 32-year-old researcher together with his 25-year-old brother. The duo is suspected of passing along information about possible terrorism targets inside France to members of al-Qaeda in the Islamic Maghreb — the North African wing of al-Qaeda.

There is no evidence that his work at CERN is connected to terrorism, according to laboratory spokesman James Gillies. All work at the laboratory is published in the open domain and is not military in nature, said a CERN statement.

Hey, maybe some al-Qaeda operative reads my blog and thinks mini black holes from the LHC have potential as a terrorist weapon. (Well, I did refer once or twice to the fact that some physicists talk of evaporating black holes having similar power to atomic bombs.)

It is also possible that my fretting about mini black holes contributed to a premature loss of virginity (this even happened in my own home town!).

Of course, given the number of readers this blog maintains, it's just as likely that I caused the election of Pope Benedict.

Technology Review: Carbon Capture Remains Elusive

Technology Review usually seems a wildly optimistic magazine, so when it has an article expressing doubts about CO2 sequestration, we should take note. Here are some reasons why government plans to rely heavily on this technology should be taken with a bucket of salt:

One of the geological challenges faced by Duke Energy and others investigating in CCS is ensuring that the pressure inside reservoirs deep beneath the surface of the earth doesn't climb too high as carbon dioxide is injected. "There are only certain safe levels that you can raise the pressure to before you get into issues of seismicity," Herzog says....

As I suspected, finding the right places to pump it in is the biggest problem, even in geologically diverse North America:

...one of the biggest remaining questions is whether sufficient reservoirs exist to store all of the carbon dioxide that may be captured.

The best-studied storage deposits are former oil and gas reservoirs capped by layers of nonporous rock that kept the petrochemicals locked deep underground for millions of years. Yet of an estimated 3,947 gigatonnes of carbon dioxide storage capacity under the U.S., only 1 percent consists of depleted natural gas and oil reservoirs. The vast majority of capacity--3,630 gigatonnes--consists of deep saline formations that have received less scrutiny.

"We're at the place where there is no problem doing millions of tonnes a year, but to solve the climate problem we need to do billons of tonnes or gigatonnes a year, and at that scale, storage becomes a real issue," Herzog says.

The Greens Senator Christine Milne was on Radio National this morning complaining that the Rudd government's plan relies almost exclusively on CO2 sequestration coming on line in (I think) 2030, and it providing the actual reduction in greenhouse gases that Australia makes. Before that, it's all overseas permits.

Her criticism is very valid, but on the other hand the Green's solution (that Australia is capable of making a rapid changeover to run purely on renewable energy) seems wildly off the mark too. (Especially if you read Barry Brook's blog.)

Why is it impossible at the moment to find any political party in Australia that actually makes sense on CO2?

An Anthony Lane moment

“The Invention of Lying” movie review : The New Yorker

The Anthony Lane review of Ricky Gervais' "The Invention of Lying", a high concept comedy based on the idea that religion is simply a lie, contains this final, somewhat biting, comment:
Audiences here should be reminded, at this point, that Gervais found his fame on the BBC, with “The Office” and “Extras,” and that the execration of religious faith, specifically Christianity—plus a reflex sneer at the fools who fall for it—has, in the past decade, become the default mode of British cultural life. It makes sense, I suppose, for Gervais to use his film to air such mockery, if spiritual belief genuinely strikes him as a lie like any other; the plan would carry more weight, however, if he didn’t use the rest of the film to air his transcendent belief in Ricky Gervais.

Why doesn't every Miss World win, then?

As the BBC says:
In awarding President Obama the Nobel Peace Prize, the Norwegian committee is honouring his intentions more than his achievements.
If he really wants to impress the world, Obama will decline to accept this, and tell the committee that he appreciates the thought, but he won't deserve it until he actually has some achievement to show for his efforts.

Lunar attack

Only an hour to go as I write this for the NASA LCROSS mission to smash into the moon. If it's lucky, the plume will show water or something else of interest under the lunar surface. Neat.

I'll be watching on NASA tv on the internet, unless I find a news show on cable is taking it live too.

Meanwhile, crashing a rocket into the moon is enough to bring out some, well, lunacy, in the form of blogs like "Do not bomb the moon". Amongst the comments by those who fear this is a bad, bad idea, I perhaps like this one best:

It’s a plot to destroy earth! A big enough chunk, like several tons of material, will be broken loose and since it’s between the moon and earth, it will eventually be caught up in earths’ gravity and flung into us much like a large astroid that wiped out all life on earth mellinium ago!

FInd a large deep cave to hide in and take enough food and for 4 years if you want to survive.

When I was bducted by aliens a few years ago, they warned me of this but nobody would listen. Now maybe they will.


UPDATE: well, that's it, and there wasn't a flash or anything to see visually. Funnily enough, on NASA TV after it, some guy admitted it wasn't clear what they had just seen - maybe the gain wasn't high enough. (In other words, he sounded as if he had expected to see something too.) Anyhow, information from other orbiting satellites will be sending back their observations soon.

The depths of racism

The discussion of racism and "blackface" that has been going on today reminded me of a BBC documentary I recently stumbled across and started watching.

I've only seen the first 15 minutes or so, but in that part (starting around the 7 or 8 minute mark) there is a pretty extraordinary section about lynch mobs in the United States in the 20th century. This is a topic of which I know little, so I had always imagined lynch mobs as comprising of maybe a few dozen men, most of them in KKK get up, getting their murders over and done with by stealth. But as the video shows, there were lynchings in which hundred or thousands of well dressed town folk turned up to view the spectacle, with many of them posing with glee in front of the corpses. Then photographs of the event were often later sold around town as postcards:



It's interesting to note that the person talking about this, James Allen, says that this aspect of American history is not one that the southern States are all that keen on being reminded of. (The introduction at this website indicates the same thing.) If you want to, you can see a flash movie of many of the lynching postcards which Allen has collected. (Although I must admit his narration is, in places, too self reflective.)

A general history of lynching in the US is also to be found on Wikipedia here.

It's remarkable to think that there could well be people in their old age today who, as a child in the first half of the 20th century, may have been taken to see the aftermath of a lynching.

It's worth being reminded as to why current American society is still getting over the legacy of this period in their history.

A proposal

Let's just save time, money and effort now, shall we, and do a deal with Kevin Rudd that he doesn't have to bother with the next election if will accept the status quo for another term? The Liberals can say that that money can be used to pay down our debt, and as such they are doing something good for the nation.

There would not be a half-interested voter in the nation who thinks that there is even the remotest possibility that the present rabble of a Coalition could win the next election.

As Alexander Downer was saying on the radio today, a change of leadership is not going to make one bit of difference. In fact, it will likely make matters worse, yet that is what the likes of brilliant mind Wilson Tuckey wants.

Andrew Bolt is again playing a disingenuous role in this: he writes well and is surely regularly read by most on the conservative side, but is encouraging the cultural divide within the party between those (who knows how many? - it seems damned few most of the time) who will accept there is a need to do something serious about CO2 and those who don't. I feel sure that, regardless of his promotion of all things skeptic about AGW, he is not convincing younger to middle age voters, and as such there is a political need to deal with the issue seriously regardless of what individual doubters about the science believe. He is naturally inclined towards conservatism, but is doing them no favours by encouraging this hopeless division.

Something in the water at Channel 9?

Hey Hey it's controversy | Herald Sun

The strangest thing about the Hey Hey show last night (apart from the evident lack of post- 1980's hair stylists in whichever part of Queensland Jackie McDonald now lives) was definitely the "is this meant to be blackface or not?" skit.

The make up did not include the 'traditional' white mouth and eyes, yet was so thickly black it was impossible to avoid the impression that it was the blackface you use when you can't quite bring yourself to do classic blackface. And then, to further add confusion, it was revealed that they were all doctors, this morning we hear two are Indian, and a clip from when they first did the skit 20 years ago indicated that at that time, their face makeup looked less "blackface" than this time.

What on earth were they thinking then? And what was Channel 9 (or the Hey Hey production staff) thinking? In the paper this morning a doctor from the group says:

"All six of us discussed this at length whether or not we should put this on because we realised it may be controversial," he said. "We did go to the trouble of checking with the production staff and they seemed to OK it."

So was there an ironic intent then - an element of "look at what we could away with 20 years ago"? Was the risk of offence to any visiting (or viewing) American completely overlooked by Channel 9, and a bunch of adult doctors? Did they only consider that it might be too soon after Jackson's death?

This is all very strange if you ask me.

I actually found Sam Newman's performance last month worse in that there was absolutely no other way to interpret it other than as 100% racism with intent. Yet that appears to have attracted much less condemnation. Let's show Harry Connick a clip of that event and see what he says.

In any event, there is something very peculiar about management in Channel 9 and their inability to see racist offence coming, if you ask me.

UPDATE: Also, is it only me, or did Daryl Somers suddenly look older last night compared to last week? Maybe it was Jackie McDonald's hair that somehow unbalanced the show into an unwelcome time warp, compared to last week's nostalgic one. All very odd.

Your bad ocean acidification news for the week

Poor Malcolm Turnbull. He sounds half reasonable to me on the topic of CO2 emissions but is caught in a bind. Even though the Rudd ETS is probably an extravagant waste of time from a scientific point of view, as is probably about 95% of all nations' approaches to greenhouse gases, people like the idea of doing something better than the idea of doing nothing. Politically something has to be done, but a divided Coalition is giving every reason for the public to think they can't be trusted to do a damn thing.

Why do no politicians talk of ocean acidification as an independent reason for taking action? Here's some more depressing news from the ocean acidification blog:

* two studies indicating bad news for corals due to effects on important symbiotic relationships

* some reef fish don't seem to like it either

* another study showing a couple of bivalves (clams and scallops) don't take lower pH well.

I saw Malcolm Turnbull on Insiders last Sunday arguing that action on AGW was the prudent thing to do given the weight of science. Quite right; but why not also mention ocean acidification, given that it appears increasingly well founded that future changes to ocean chemistry are a gigantic ecological crapshoot.

Delicious

Fries with your Mona Lisa? Big Macs move on Louvre

They'll be protesters in the streets of Paris threateningly waving french sticks around over this one. But as the story notes:
The French seem to love McDonald's. While business in brasseries and bistros is in free fall, the fast food group opened 30 outlets last year in France and welcomed 450 million customers.
As for my current opinion of McD in Australia, I note:

* the Angus beef burgers are surprisingly bland. Neither my wife nor I were particularly impressed. I would stick to the McFeast if I were you.

* the deluxe cheeseburger is good for a quick lunch

* the hot coffee from the machine is pretty good, but the new iced coffee is just a premix from a bottle and is not so good

* some of the crispy chicken burgers are pretty good.

By the way, it would seem that the Australian menu is significantly more extensive than the one in France, especially when it comes to chicken choices.

In praise of cities

The Green Case for Cities - The Atlantic (October 2009)

Evolving goodness (and yes, back to God again)

Frans de Waal's The Age of Empathy. - Slate Magazine

Further to today's lengthy post on the ultimate value of emotions, it's worthwhile reading this article on the increasing research into the animal predecessors to the "good" human emotions.

(You should at least read it to see how empathy is not evenly spread around the primate world. Baboons are apparently not very nice.)

Such "bottom up" arguments for the evolution of a human sense of morality are used to attack the "top down" (god derived) arguments for our sense of morality, of which CS Lewis was a notable proponent. In Mere Christianity, Chapter 2, Lewis tried to answer "objections" that morality is really all about instinct by arguing that if you have competing instincts in facing a particular situation, there is a third bit of your mind by which you judge one of those instincts as more worthy than the other. He has various ways of proposing why it is not merely a case of the strongest instinct always winning, but I don't really have time to set them out here.

Lewis' arguments still seem to me to be quite clever, but given the mystery of the workings of the inner mind, I can certainly see how they are also far from conclusive.

In any event, I'm not sure that increasing evidence of animal instinctive kindness is necessarily threatening to Catholic style belief in God, which by and large has accommodated evolution. Why should it surprise us that what we value in our feelings should be shared in some instinctively understood way by our closest animal relatives? The real issue (and here I guess I am more or less following the Lewis line) is how our human rationality deals with those instincts, and whether there is reason to believe that there is God who cares about those choices.

Against the silence

It's pretty quiet around here lately. Sure, Tim still comments sometimes, but Geoff and Caz haven't for a while, and I don't know what's happened to MCB. I get the occasional new commenter, which I don't always respond to. Is that impolite? Maybe I should start replying to the spam comments that turn up. WOW Gold, indeed.

Just feels a bit like rattling around an empty house on a Sunday afternoon here sometimes. (I never got the hang of Sunday afternoons. They still strike me as unsatisfactory.)
