Good Germans

My current burst of off-blog activity will soon be at an end. Here's another recommendation to fill in the time.

Last Friday, I saw an episode of a German documentary series The Wehrmacht, entitled "The Resistance". It was a quick history of the resistance within the German army in WWII, and was pretty fascinating viewing.

The episode is up on Youtube in several parts, and it's well worth watching if (like me) you are only vaguely aware of the conspiracies to kill Hitler . (There are stories of smaller acts of heroism too, which are always encouraging to hear.)

The last episode in the series, which is about the German's disasterous decision to continue fighting a losing battle, is on SBS TV tomorrow night (Friday) at 8.30.

I'm somewhat distracted at the moment, but in the meantime, have a look at a very appealing cliff-top house near the sea in Chile.

(I must admit, though, as soon as I see extensive use of glass near the ocean, there's a voice from the boring, practical corner of my mind whispering "endless cleaning".)

Free TV

Sharp Unveils Solar-Powered TV

I'm not sure just how many of the 1.6 billion people who live off the grid can afford to buy a TV, solar cell and battery combo so that can watch the TV signal that their remote area probably doesn't have anyway, but it will be a cool item for the ostentatiously Green to have in the city.

Notes of minor interest

School holidays: it must be family-friendly movie time. We went and saw Kung Fu Panda yesterday. It's good but not great. The animation itself is often lovely, but the fights are a bit too frenetic for my taste. It all seems to be over in a flash. Of Dreamworks animation, I would rate the first Shrek and Madagascar as better.

Speaking of Madagascar, they showed a trailer for a sequel that I had forgotten was coming. Here's hoping it can overcome the inevitable challenge of loss of novelty. (The penguins seem to have a lot of screen time in the preview, which is a good sign.)

The cinema also showed the shorts for Mamma Mia. It's amazing how long flakey, vacuous Euro pop can last, isn't it? I didn't rush out to see the stage show, so the movie is the first time I knew what the plot was about. Something about "free spirited" mother with adult daughter whose father could have been any one of 3 different men. The kids in the audience seemed to like the music, but this plot line may be a little hard to explain to any under 10 year old who still has a firm connection in his or her mind between marriage and having babies. Still, Tony Abbott could be accused of causing the same difficulty a couple of years ago, I suppose.

No matter how strong the reviews might be, it's not going to revive the romantic musical as an art form.

UPDATE: I forgot to mention that the cinema also showed the preview for The Love Guru. It made the film look fairly innocuous, and raised some laughs, so let's hope parents actually read reviews and know how badly it has performed in the States before they send their kids off to see it.

More on acidification

Acidifying oceans add urgency to CO2 cuts

This report notes an article on ocean acidification that is to appear in the July 4 issue of Science (although I can't see mention of it yet on the Science website.)

As I suspected, it's bad news for you oyster and mussel lovers out there who expect to be around in 50 year's time. But the worrying thing is, it is extremely difficult to be certain how it will affect the oceans and the planet overall:

"We know that ocean acidification will damage corals and other organisms, but there's just no experimental data on how most species might be affected," says Caldeira. "Most experiments have been done in the lab with just a few individuals. While the results are alarming, it's nearly impossible to predict how this unprecedented acidification will affect entire ecosystems." Reduced calcification will surely hurt shellfish such as oysters and mussels, with big effects on commercial fisheries. Other organisms may flourish in the new conditions, but this may include undesirable "weedy" species or disease organisms.

Though most of the scientific and public focus has been on the climate impacts of human carbon emissions, ocean acidification is as imminent and potentially severe a crisis, the authors argue.

"We need to consider ocean chemistry effects, and not just the climate effects, of CO2 emissions. That means we need to work much harder to decrease CO2 emissions," says Caldeira. "While a doubling of atmospheric CO2 may seem a realistic target for climate goals, such a level may mean the end of coral reefs and other valuable marine resources."

While on the topic, I note that Jennifer Marohasy recently posted 2 photos from diver Bob Halstead showing an area in New Guinea which has (apparently) volcanic CO2 bubbling up through the sea floor.

As with the recent Nature study of a similar site in Italy, the photo indicates that sea grass really loves those conditions. Halstead also says there is a "healthy reef" metres away. But it's impossible to take that as proof that corals will happily survive acidified oceans unless you have proper measurements of the pH in the area. Indeed, we don't even know for sure that the gas is all CO2.)

I think we can take it as a sign that sea grass will do well enough in future, but just how ecologically healthy is it to have sea grasses booming in areas where they previously have not been? Especially if they replace areas that are have been extensively coral for tens of thousands of years?

I also see that the ocean acidification sceptics in the comments following that post are relying solely on Dr Floor Anthoni as their source. As I have noted before, the good doctor does not claim to have any qualification in science or biology, and appears to be pretty much an enthusiatic amateur when it comes to marine ecology and chemistry. That's not to say that amateurs can't do good science, but if you are promoting theories that are somewhat outside the mainstream, the lack of a qualification even close to the field (the qualification is in computers and electronics in Dr Anthoni's case) is not exactly adding to your credibility.

Dr Anthoni appears to have irritated many scientists in the past with claims relating to fisheries, etc. To his credit, he appears to at least be open about the disputes he has had, and you can read the exchanges on his own website.

Still, it gives me no comfort if he is the primary source of the ocean acidification sceptic's arguments.

Kerry and Kevin sitting in a tree...

Why on earth is Kerry O'Brien still delivering such velvet-gloved handling of Kevin Rudd? Have a look at the transcript of last night's interview, mainly about the COAG meeting and its decisions relating to the Murray-Darling. The short version goes like this:

O'Brien: Mr Rudd, scientists say there is an immediate crisis in the Murray, has COAG actually addressed that?

Rudd: [waffle, waffle, waffle, asks himself and answers 4 questions ] Yes. Sort of. It'll take a year or two, but yes.

O'Brien: So, are you really, really sure you can promise us that that's true?

Rudd: well, I can't make it rain, but [asks himself 3 questions, waffle waffle waffle] yes. In a year or so.

O'Brien: Please forgive me, I'm now going to ask a really long question. [Short version: do you think emissions trading will be a really big issue for you?]

Rudd: we were elected to make tough decisions, [waffle waffle waffle] yes, more or less.

It seems to me that O'Brien's questions indicate that he knew there were grounds to specifically attack the COAG meeting for in fact refusing to do the immediate thing that the scientists demanded, but he refuses to put tough questions directly to Rudd. (Read the reports from Fairfax, News Ltd and the ABC that complain about the COAG result here, here, here, here and here.) Instead, O'Brien's questions are all open-ended invitations to Rudd to answer in any way he pleases. Mild scepticism would seem to be the strongest emotion O'Brien can bring himself to display in his interviews with our PM.

O'Brien has always treated Rudd this way, and I want to know why. Has Rudd's staff got some dirt on him or something? I find it truly puzzling.

Go Japan

Farming Solar Energy in Space: Scientific American

According to the article, the Japanese are looking into space based solar power:

...by 2030 the agency [JAXA, Japan's equivalent to NASA] aims to put into geostationary orbit a solar-power generator that will transmit one gigawatt of energy to Earth, equivalent to the output of a large nuclear power plant. The energy would be sent to the surface in microwave or laser form, where it would be converted into electricity for commercial power grids or stored in the form of hydrogen.

Well, can't accuse them of not being ambitious.

Hard Friends to please

I see via Andrew Bolt that ABC is doing much, much better than it was 10 years ago. Of course, this turnaround did just not happen since Rudd was elected. It happened under the Howard government, who the Friends of the ABC thought was starving it to death and beating it into ideological submission.

Friends sometimes just don't know what is good for them.

Recent hits

Exploding asteroid theory strengthened by new evidence located in Ohio, Indiana

So, maybe an asteroid hit Canada about 13,000 years ago, causing a wee bit of upset to the climate in the process. Interesting theory.

On a similar topic, to commemorate its100 year anniversary, Australia's Duncan Steel wrote an article at Nature about the various theories that have been offered over the years regarding the Tunguska event. Unfortunately, it's behind a paywall, but Jerry Pournelle's email page seems to have copied it all out. Good reading.

Recommended reading

A few recent articles of interest:

* The New York Times magazine looked at the demographic crisis of Europe (and some other countries). So you thought Mark Steyn was exaggerating? How about this:

Around the time that President Kennedy went to Germany and gave his “Ich bin ein Berliner” speech, Europe represented 12.5 percent of the world’s population. Today it is 7.2 percent, and if current trends continue, by 2050 only 5 percent of the world will be European.

And bear in mind the age of that 5% too:

....in 2025, 42 percent of the people living in India will be 24 or younger, while only 22 percent of Spain’s population will be in that age group.

The article offers explanations for the low birth rate of most European countries, and the relatively high birthrate of the US, but they still don't get around to quite explaining Germany. Worth reading anyway.

* The Atlantic Monthly has an interesting article about how GM is putting all its eggs in one electric car basket. I wouldn't be buying shares in the company at the moment.

* While your at the website, have a read about the Price Tower, a 19 story high rise building Frank Lloyd Wright designed in Oklahoma. It doesn't look much from the outside, but the article makes it sound like it's worth a visit. The writer knows how to use redundant information for amusing effect:

Wright, who is best known for his low Prairie-style buildings, had a complicated relationship with tall buildings, calling one an “incongruous mantrap of monstrous dimensions.” Yet late in life he created drawings for a 528-story skyscraper featuring atomic-powered elevators with five cabs strung vertically in each shaft. (It was never built.)

* Still in the US, the Observer's Ruth Fowler takes a long, cross country trip on Amtrak and enjoys it quite a lot. (Her article reminded me of a few long train trips I took in Australia as a teenager/young adult. It is a social way to travel, and it's a pity that it is no longer all that economically attractive.) Fowler makes me laugh with this account:

Amtrak employees themselves assume key roles in this peculiarly theatrical mode of travel. En route to Montana I was woken in the morning by a lady trilling over the intercom: 'I'm singing in the rain. Just siiinging in the rain! I'm brewing COFFEE! Mmmm, coffee! Rich, robust, strong, masculine, earthy coffee! Can you smell it? It wants you. This coffee wants you. I'm in the lounge car. Ask for Miss Olivia. I'm waiting for you with my enormous coffee pot. MM-mmm!'

* Bryan Appleyard has been in fine form lately, having spent a lot of time recently in America with some unusual consequences (a passion for cowboy boots, for one.) Some recent posts of his which are particularly enjoyable: all about religion and excretion; an assessment of Bill Gates as he departs Microsoft; a certain problem with people sometimes not getting Bryan's tone.

Just go read him regularly.

Fixing Firefox 3

If, like many, you have been surprised by the horribly ugly and strangely behaving drop-down address bar in Firefox 3 (the "awesome bar", apparently), there is an add on that at least stops it pulling unvisited bookmarks into it. (If I want to use a bookmark, I just go to the bookmarks tab.)

It's Hide Unvisited 3, and it appears to work well enough.

Actually, I now see there is another add on which apparently gives you back something very close to the old bar. Maybe I should try that too.

Meanwhile, work and stuff continues to bother me.

The future is green

Alternative energy: Microbe economics | Business | guardian.co.uk

I'm still busy, but in the meantime you can read about the potentially bright future of algae.

Did you know there is a National Algae Association? No, nor did I.

The only thing that worries me about the idea of huge vats of algae being grown for fuel and (potentially) food is that it's a little too reminiscent of Soylent Green. Let's hope they never decide that adding the occasional body is a good fertilizer for it.

Random notes

* Saw Q&A last night. Tim Blair comes across as more restrained than on his blog. Greg Hunt has a truly ghastly way of smiling, and the hair style doesn't help. He badly needs a face coach, or something. Bill Shorten, on the other hand, really seemed very likeable in the more relaxed setting. I thought in the election campaign that he could be a bit dull and inflexible in one-on-one interviews, but on last night's evidence, you can really see the public warming to him as human personality and a pretty centrist sounding laborite. Much more likeable than robotic Rudd.

* Michelle Grattan has been very, very kind to Rudd in most of her assessments of this new government, so when she says he's not gone so well in the Asian diplomacy stakes, you can believe it.

* Some Labor figures are starting to talk nuclear. I suspect the swing will happen before the next election, and the Liberals will not (if they are sensible) disagree. The only problem then may be Greens in the Senate, if something legislative is needed to establish the industry.

* In the Lefty blogosphere, good to see the insults fly in comments at Club Troppo, especially when one of the targets is my vote for the most irritating blogger who keeps getting noticed: Ken Lovell.

And as many people at noticed, Kim at LP seems to have had a brain meltdown this week too. She is best ignored in 99% of cases, anyway.

Raiders of the Lost haemorrhoids

Well, the opinion sale is going slower than expected, so here's something to keep you entertained.

There's an article in Biblical Archaeology Review that is entitled "Did Captured Ark Afflict Philistines with E.D.?". The "E.D." referred to there is erectile dysfunction.

Unfortunately, the article is behind a paywall, but it would seem that the general gist is that the Bible says the Philistines suffered "tumours" after they took the Ark of the Covenant from the Jews, and some translations have interpreted this to mean haemorrhoids. But apparently this article suggests that the effect on the Philistines might more appropriately be interpreted as erectile dysfunction. God really knows how to punish those manly rampaging Philistines!

Someone comments about the story appear in this forum, and the guy makes the useful suggestion that the general idea of tumors, painful swellings or erectile dysfunction being caught from standing too close to the Ark might mean it was radioactive! This is an oddly appealing theory.

I note, however, that it didn't seem to work on Indiana Jones.

Now, get back to work.

UPDATE: here's a better explanation of the argument in the article:

The short version: 1 Samuel 5-6 recounts how the Philistines captured the Ark of the Covenant from the Israelites in battle. They took it back to Ashdod and put it in front of a statue of Dagon. The next day they found Dagon toppled. They propped it back up, but this kept happening. The hand of the LORD was heavy on the Ashdodites, and he afflicted them with [or in their] ‘opalim.

The meaning of ‘opalim is uncertain. It has traditionally been taken as hemorrhoids. The KJV renders emerods; most modern translations are squeamish about this and euphemize this as tumors or sores. The root ‘ophel is used for the upper city of ancient Jerusalem, and conveys the sense of a hill, a height or a rise, and thus a swelling. It’s kind of hard to imagine what the five golden hemorrhoids would have looked like.

But there is a theory that the ‘opalim were not hemorrhoids, but rather penises. This is driven by archaeological discovery of cultic situlae in the shape of penises, which were actually a common cultic representation in Philistia. (The print version of the article has lots of pictures.) The sense of something that rises would fit.

Someone in the comments following suggests that in fact the affliction might have been priapism!
That would be, I suppose, a particularly ironic curse for God to send upon the Philistines.

A Colbert moment

This segment from tonight's Colbert Report seemed particularly funny:

Mini black hole safety report finally here

Backreaction: Black Holes at the LHC - The CERN Safety report

The above post at Backreaction tells us about the CERN safety report which was finally released last Friday.

I haven't had time to read it yet, but apparently, as expected, it uses the example of long lived neutron stars as the major argument as to why micro black holes could not be a danger to the earth.

This may well end up marking the official end of my concerns about this as a issue, but I should read it first. (And one immediate issue I can think of is whether you can really use the cosmological argument as a close enough analogue to the way many black holes could be created in close proximity in a short space of time at the LHC.)

For any of you who think that it has been a waste of time worrying about it in the first place, you should read what actual working physicist Bee says in her comments on the above post:

I think it is good they wrote this report and from a legal point of view I can understand that some people found the issue was not appropriately addressed. CERN should have taken these concerns more seriously earlier then it wouldn't have come so far. In this particular situation I find the argument about the black hole scenario ridiculous, but that's because it's a topic I happen to have worked on and know something about. If I consider experiments in other fields where I couldn't tell exactly what the story is, I certainly would appreciate a similar report. The new CERN report I find extremely clearly written and I hope this will suffice and be the end of this catastrophe scenario.

This is a completely different attitude, and a very welcome one, from that expressed by most physicists when lay people started asking questions. (I'm looking at you, the guys at Cosmic Variance.)

Toxoplasma research

Indiana U scientists uncover potential key to better drugs to fight toxoplasmosis parasite

I know I am probably the only Australian blogger who obsesses about toxoplasma gondii and its evil cat hosts, but someone has to do it.

Anyway, there is research going on that might lead to a vaccine. Good. The mind bending parasite might be defeated yet.
