Silly hats and academia in Japan

An interesting article from the Japan Times about Japan and overfishing. It starts off talking about a famous TV fish expert:

In September, the TV personality known as Sakana-kun was appointed to the position of guest assistant professor by the Tokyo University of Marine Science and Technology.

Famous for his childish demeanor and blowfish-shaped headgear, Sakana-kun certainly knows his fish, and his lack of a college degree doesn't detract from his reliability as a marine expert. Having turned a childhood obsession with octopi into a lifelong study of sea life and all it entails, he first gained attention on the TV Tokyo contest show "TV Champion" when he beat out other piscine otaku with the depth and breadth of his knowledge: the contestants also had to have an understanding of fish cuisine, which is more important on TV than the zoology stuff.

Sakana-kun's motto is "Take a look, take a bite (Mite miyo, tabete miyo)," which makes him the perfect fish expert for TV even beyond his big smile and ingratiating manner.

Hmm, I want to see what a self-educated, childish, blowfish-headgear-wearing fish expert looks like. Here he is:


He just looks...annoying. Remember, he has been appointed an assistant professor at a Toyko University.

Anyway, the rest of the article gets more serious in talking about how the Japanese need to start eating less tuna (they account for 40% of world consumption of bluefin tuna, and 25% of all tuna!)

Kim must be very annoyed

I reckon the thing annoying Kim Beazley most about the leadership challenge would be that did all that dieting and workouts in the gym for no political purpose. Oh well, if he loses he can always console himself by forgetting about the diet completely over Christmas.

On Insiders last week, Kim made it clear he was very happy to have his weight loss noticed:

BARRIE CASSIDY: It comes up periodically, too, questions are being raised about your health. Physically, clearly, you haven't been in a shape as good as this for a long, long time. But you did have that recent illness?

KIM BEAZLEY: The illness is fine. My physical shape very kind of you to say that. I've been working very hard on the subject of my physical structure and on the whole I'm being successful with it.

Actually, the way he skipped over the illness question so quickly seemed just a little suspicious to me. Of course this is pure speculation, but I wonder whether part of the reason for the leadership challenge (which all commentators agree is unusual in that it does not appear to have been instituted by any contender) is due to lingering concern by close colleagues about his memory or ability to concentrate.

Teachers and The Age

It's a match made in heaven, lefty teachers and The Age. Big union rallies are being held today, to what end I don't know. It's about a year from a Federal election, and there is no way rallies of whatever size are going to persuade the Howard government to retract its IR legislation after it just had its constitutional right to create it confirmed by the High Court. (Maybe that is the reason for the rallies, a pointless whinge about losing a High Court case.)

So, teachers today in many States are taking the day off to attend these rallies. Here's their justification from The Age letters today:

... I am obligated to stop work so that, hopefully, students at my school do not have to join a workforce where there is no job security, no basic rights and no collective agreements.

I look into my classroom each day and see a class full of students who have hopes, ambitions and dreams which would not be fulfilled under a Howard Government.

Maybe teenagers have changed since I was one, but I somehow doubt they dream all day of the fantastic collective bargaining agreement their union will win for them.

And from a teacher sympathiser:

WHEN teachers took strike action I would always keep my child at home. His absence note would explain that I kept my child at home because I did not want my child surrounded by teachers who were so selfish that they would not surrender a day's pay to fight against injustice or so dull that they could not comprehend the importance of fighting injustice. I encourage all parents to send such messages to schools and to John Howard.

Ohh..we don't want our child contaminated by all those unjust or dumb teachers who happen to take a different view of where the balance should lie in industrial relations, do we?

Look, I'm not saying people don't have a right to disagree with the Howard government's policies on IR and to fight tooth and nail to do the only thing that will change it - elect a Kevin Rudd government. (Beazley has only got to make one more slip of the tongue in the next 6 weeks and he is gone.) But what irritates me is the preciousness of the arguments on display here, that suggest the issue is so dire and immediate that teachers must attend (even when they are not personally affected, as no public sector teacher would be) and that the rallies are going to achieve something.

The lonely job of being anti-Dunlop

I still don't get why Tim Dunlop, now blogging courtesy of News Limited, is not attracting much negative attention from the Right.

JF Beck has ripped into Blogocracy , and I added my comment of support. But why is there so little challenge of Dunlop on his site?

For anyone who cares, I am the lonely "Steve from Brisbane" who has been posting critical comments at Blogocracy. Here are some examples of matters Dunlop has been excited about recently:

1. Ex SAS officer Tinley criticises the government's decision to go into Iraq in what was obviously a highly politically motivated attack. Tim Dunlop can hardly contain himself:

Can all the pretending stop now? Have we finally reached a tipping point? Will comments today by war hero and former SAS officer Peter Tinley, finally give people across Australia—others in the military, the media, members of the Government—the courage to call the bluff on the prime minister’s discredited defence of the war in Iraq?....

Could there be a more devasting assessment from someone so intimately involved and so obviously dedicated to the military and to the defence of his country?

When it turns out within a couple of days that Tinley is a long time member of the ALP who has been in discussions about preselection, Dunlop can't see why people take the view that it was cynical media manipulation to make this attack without disclosing his personal incentive. Even long time Dunlop supporter Aussie Bob could see the point, I reckon, just that he thought it was funny that The Australian was sucked in.

2. Dunlop has been carrying on like a pork chop about how talk of challenge to the leadership of Kim Beazley is to a major degree the fault of the media, and News Limited in particular. His mate Aussie Bob posts at tedious length about how the media misreads polling all the time (conveniently forgetting how good the Liberals have been at gaining ground during Federal election campaigns). Today, Mark at Lavartus Prodeo agrees whole-heartedly; it's a regular Beazley support group.

Boys, boys, if the ABC and Fairfax press are running with leadership speculation too, doesn't this suggest the primary source of the problem is within the Labor party itself? Tonight The Age reports:

Supporters of a change have resolved to make no move before next week to maximise the focus on rallies against workplace laws being held today. But they rate the prospect of an approach to Mr Beazley to step down, or even a challenge by Kevin Rudd as "50-50".

No, no, the media should just ignore talk like that.

3. This one surprises me most: Dunlop posted a YouTube video purporting to show "White House manipulation" of video when it had been thoroughly debunked by Michelle Malkin and others weeks ago. When commentors point this out to him, he posts a not overly obvious semi-retraction at the bottom of the post as an "update", but leaves the offending video in its star position at the top. Tim Blair, you must be following Blogocracy, and if had happened on some other lefty blog I imagine you would have lept on this blunder with enthusiasm. (I remember Tim D let Tim B temporary host his blog while Blair had technical problems. Has this led to a reluctance to criticise him?)

4. Blogocracy has really become an exact clone of the old Road to Surfdom, including now the use of the "Howard's funny face" at the top of some posts. What's more, he posts about how the Left is so much more successful in blogging than the Right, citing Tim Blair as the only successful right wing blogger. Again, I would have expected some response from Blair, but none. Here's what I posted about this at Blogocracy:

Yes Tim, blogs such as yours add so much to current debate when you post a YouTube “White House manipulation” story as if it hadn’t been thoroughly debunked 3 weeks ago. (By the way, your semi-retraction at the bottom of that post is pretty half arsed. If you want people to really know that you think there probably is nothing to that video, why not put an update at the top of the post where people will clearly see it. Or do you think it isn’t conclusively debunked?)

The other interesting thing about that YouTube video is how it has about 213,000 views, compared to the debunking YouTube effort (as linked to by Malkin) has had about 1/7 of that. There is no doubt at all that the Left wing blogshphere is better at constructing an echo chamber, but I don’t see that as something to be proud of.

(I also reckon that the Left’s natural constituancy - students, academics, public servants, and the underemployed - simply have more [time] to spend on listening to the echo chamber than those on the Right.)

As for Blogocracy, it is rapidly going the way of SMH’s Webdiary. I reckon those who disagree are not bothering posting much because it is clear that the site has its own cheersquad that is never going to change its mind on issues surrounding this Howard government. This is not a healthy sign, and frankly I can’t see why News Limited would be thinking it was worthwhile to do a virtual transplant of Surfdom to here. (I would say the same if any other currently free website was transplanted here too.) In fact, I don’t get the whole “every columnist is now a blogger” thing either, unless readers are going to have to pay for the privilege sometime in the future.

To say something positive: Tim D obviously maintains a level of civility at his blogs, allowed in my increasingly critical posts, and is not exactly the "mad" Left.

But: there are many, many issues on which he is impervious to persuasion, and his anti-Howard schtick runs into the juvenile. If News Ltd wants to be part of blogging because it sees it as an interactive medium to promote discussion amongst its readership, why would it pick a private blog like Surfdom, which had clearly not been attracting much in the way of dissenting discussion, and let it be cloned?

It is just all puzzling to me. (As is the fact that Tim Blair has linked to posts here a couple of times over the last year, but there is no sign that I will ever be added to his blogroll!)

Latest Slate Hitchens

From Hitchen's latest column in Slate comes this key paragraph:

The objectionable thing about the proposed Baker-Hamilton "talks" is not that they are talks but that they give the impression of looking for someone to whom to surrender. And they have, apparently, no preconditions. It would be an excellent thing to have direct negotiations with Iran, for instance, with all matters on the table. But if the mullahs did not have to sacrifice their ongoing nuclear deception in order to get to that table, then all the efforts of the Europeans, the United Nations, and the International Atomic Energy Agency to get them to do so would have been shown to be risible. With Syria, there is an even more intelligible precondition to be announced. Most people are unaware of this fact, but Damascus has always refused to recognize Lebanon as an independent state. There is no Syrian Embassy in Beirut. Implicitly and explicitly, this suggests that the country is regarded as an actual or potential part of a "Greater Syria." Is it really too much to demand that Syria acknowledge the self-determination, or "right to exist," of a fellow member of the Arab League? Without this line of demarcation, for one thing, the "withdrawal" of Syrian soldiers and police is a merely tactical thing; a retreat over the horizon while the Assad dynasty waits for better days. These "better" days may well not be long in coming.

The crisis in Hollywood

A long article in The Independent (found via Pajamas Media) talks about the current decline of Hollywood. There is nothing to disagree with here. We have been going through a lean period for enjoyable, quality Hollywood fare for some years now, and it is not clear when it will end.

A secret harvesting of eggs ?

This article about how medical research may be getting eggs for use in stem cell research is interesting. It would seem that supporters of the recent Bill about this do not understand all of the possibilities it may allow.

Ms Patterson has claimed her Bill permits only the creation of cloned embryos, never sperm-egg in-vitro fertilisation embryos, for research. But her Bill does indeed permit the IVF creation of a sperm-egg embryo using an egg from an aborted fetus and an adult male's sperm. This hidden provision to create fertilised embryos for research using ova from an aborted fetus was directly addressed by the Senate inquiry.

Ms Skene, for the Lockhart committee, acknowledged: "The committee's recommendations envisaged that an embryo could be created for use in this way." And no, she said, the committee had not canvassed public attitudes to such a practice.

Hard to imagine

This must be "male contraception week" in the British media. Following my recent post on vasectomy, The Guardian discusses some ideas for male contraception under investigation. This includes one idea which might be a hard sell:

There are several at various stages of development, with the latest a single-dose pill that produces a "dry orgasm", the slightly eye-watering notion that the man experiences sexual pleasure, but does not produce any semen. ...

Under normal conditions, rhythmic movement of muscles running lengthways along the vas deferens and circular rings of muscle around the tube propel sperm during an ejaculation. But the two drugs [a schizophrenia and blood pressure drug] have the side-effect of shutting down the lengthways muscles. "They relax it," says Amobi. That means the sperm don't go anywhere. Usefully, the effect wears off 12 to 24 hours after taking the pills.

Um, I guess you kind of don't know if it has worked until it is too late. And if it had to be used with a condom for that reason (or for safe sex reasons,) there would be no point in using it at all.

Women in Afghanistan

The Guardian has a fairly long article about the continuing plight of women in Afghanistan. Although it opens as if its sole point is to criticise the failure of Western intervention to help maintain early improvements to women's status, it does acknowledge that women are still far better off than they were under Taliban rule, and no one thinks it would be good for the West to leave.

Some specific examples of spectacularly bad treatment of women there:

Human Rights Watch says that a third of districts in Afghanistan are now without girls' schools, due to attacks on teachers and students by the Taliban and other anti-government elements; and traditional practices such as child marriage and baad, in which women are exchanged like objects in tribal disputes, still continue unchallenged. ...

Joya talks like this to me, furiously, for more than an hour, almost weeping as she catalogues the crimes against women that still keep them in a state of fear: from Safia Ama Jan, the leading women's rights campaigner assassinated in Kandahar earlier this year, to Nadia Anjuman, a poet murdered in Herat last year; from Amina, a married woman who was stoned to death in Badakhshan in 2005, to Sanobar, an 11-year-old girl who was raped and exchanged for a dog in a reported dispute among warlords in Kunduz in northern Afghanistan last month.

She is desperate for people to take account of the silent women whose voices we never hear. "Afghan women are killing themselves now," she says, "there is no liberation for them." This is not just rhetoric: the Afghan Human Rights Commission recently began to document the numbers of Afghan women who are burning themselves to death because they cannot escape abuse in their families.

Makes worrying about the glass ceiling in the West seem a bit of an indulgence.

An unappealing concept

Apropos of nothing, I just stumbled across a (literally) "high concept" business on the Internet:

A unique event meant for anyone who wishes to transform an ordinary meal or meeting into a magical moment that will leave a lasting impression on their guests!

Dinner in the Sky takes place at a table suspended at a height of 50 metres by a team of professionals. Benji Fun, our partner in this event, is the worldwide leader for this type of activities.

This is what it looks like:


My attitude to heights might be little unusual. I like flying, and I enjoy it more on a small aircraft than a huge one. (I feel it is more "natural" for a Cessna to fly than a 747.) But when it comes to buildings, I can get a little nervous standing on an apartment balcony if it is any more than a few stories up.

Maybe it's the tilted angle of that photo, but for some reason it makes me feel queasy just thinking about trying to enjoy food while strapped into a seat with 50 m of air between my backside and the ground.

(By the way, it seems Boing Boing has not posted on this one yet, even though it is right up their alley.)

The pain that only men can feel

For those male readers contemplating having a vasectomy, The Times has an article on the uncomfortable issue of long lasting pain. The solution for some men sounds rather radical:

Dr Black says: “I’ve seen a handful of cases in which pain has continued beyond nine months after the operation.” He suggests that the debate about longer-term post-vasectomy pain exists because of the industry that has sprung up around it. “Some urologists, especially in the US, are making money by removing the epididymis or even the testicles of men in post-vasectomy pain, promising that the pain will disappear,” he says. “But I’ve never seen anyone who really needed this.”

Well, removal of testicles should completely remove the fear of the loose ends rejoining, as is known to happen from time to time.

The problem with this type of issue is that it is very easy for doctors to think it's all in the mind. However, if a specialist himself suffers it, well that's different:

Dr Andrew Dawson, of the Hartlepool Vasectomy Reverse Clinic, is not so sure. He, too, has suffered post-vasectomy pain: “My own problems made me realise that this was something we needed to take seriously. I’ve come across men whose pain has taken over their lives. We’ve performed vasectomy reversals (re-joining the cut tubes) for them, which have been 100 per cent effective and eliminates the pain.”

What might be causing the pain?:

He believes that he can explain what is happening. “Vasectomy is pretty crude really; it just traps sperm in the epididymis. In some, often highly sexed, men this can cause the epididymis to become swollen. Eventually it can rupture — Americans call this a blowout — which will solve the problem naturally but can be very painful. A vasectomy reversal can reduce the pressure.”

I remember asking someone - I forget who - years ago about what happened to sperm that could not get out after a vasectomy. The vague suggestion was something like "the body just absorbs it." Maybe in most people it does, as we don't hear of "blowouts" all that often. Still, it's good to know that my puzzlement about this was in fact a good question.

By the way, this was all dealt with in detail in an episode of ABC's Health Report in 1997! I wonder if there is adequate warning of this possible complication being given now?

Red, white and blue butterfly

I spotted this particularly attractive butterfly in the yard today and took this pic. (The butterfly itself is exactly how the camera caught it; but the background has been smudged and blurred by me with an image editor program and my little tablet.) It looks very good if you view it full size.

From the annals of useless commentary...

Alan Ramsay in the SMH today:

Our Prime Minister lately is behaving and sounding very much like the Paul Keating of old in the ebullience of his arrogance.

Keating in Labor's 13th year of office was insufferable, however mellow the memory. Howard nearing his 12th displays much the same underlying contempt, only differently.

And in The Australian, Phillip Adams continues his one man campaign to "out" every gay (or bisexual?) man he has ever met or heard about.

Phillip, all of this will be received without criticism when the authorised biography with full details of all your indiscretions is available.

When in doubt, parachute in the historians

From the International Herald Tribune:

Last week, Kofi Annan gave the Middle East a history assignment. Speaking in Istanbul, the UN secretary general identified the competing historical narratives of Palestinians and Israelis as central to the Middle East crisis and the alleged clash of civilizations between Muslim and Western worlds...

To bridge this gap in public perceptions, the [UN] report recommends the drafting of a white paper analyzing the Israeli-Palestinian conflict dispassionately and objectively, giving voice to competing narratives on both sides. In recommending historical research as a precondition to political dialogue, the UN report has identified a core problem that dates back to the spring of 1919 when three politicians, Woodrow Wilson, Lloyd George and Georges Clemenceau, disregarded history in favor of political expediency. Since then, political leaders have grappled vainly with the consequences of this "peace to end all peace" in the Middle East.

By acknowledging the importance of history and seeking to engage historians in the peace process, Annan is creating an opportunity for new approaches to resolving this seemingly intractable conflict.

Maybe it doesn't pay to be too sceptical about anything that could possibly help in the Middle East. But really, I imagine one side having much greater difficulty than the other in being persuaded by historians' white papers. (Here's a hint: it's not the side that has trouble accepting the extent of the Holocaust, and does nothing to stop theProtocols of the Elders of Zion being re-hashed as truth.)

Dawkins' declaration of war

Richard Dawkins 's book "The God Delusion" and his vigorous campaign to get other atheistic scientists to actively repudiate all forms of religious belief is attracting a lot of attention.

(For those who haven't been following this: Dawkins won't even tolerate those who tolerate religious moderates. In his view, giving comfort to any form of supernatural belief means you are also giving comfort to the fundamentalists.)

For a good backgrounder on this campaign, the lengthy Wired article from last month was pretty good. More recently, a New York Times article talks about a conference where Dawkins sought to rally the troops against religion.

Well written anti-Dawkins material can be found in the reviews of Terry Eagleton and Marilynne Robinson. Criticism about how Dawkins treats Stalinism and Nazi Germany so as to try to paint them as not really the product of atheism is well dealt with in Dinesh D'Souza's article here. Even those who are generally sympathetic to his cause often express concern that he is far too stroppy in his rhetoric and is actually hurting the cause he promotes.

He refuses to accept even the "non overlapping magisteria" argument (the view that religion and science are fundamentally about different things, and therefore can co-exist peacefully.)

One of the stupidest comments about all this I found being made by a physicist blogger Sean Carroll over at Cosmic Variance:

Scientists who do try to point out that walking on water isn’t consistent with the laws of physics, and that there’s no reason to believe in an afterlife, etc., are often told that this is a bad strategic move — we’ll never win over the average person on the street to the cause of science and rationality if we tell them that it conflicts with their religion. Which is a legitimate way to think, if you’re a politician or a marketing firm. But as scientists, our first duty should be to tell the truth. The laws of physics and biology tell us something about how the world works, and there is no room in there for raising the dead and turning water into wine. In the long run, being honest with ourselves and with the public is always the best strategy.

Does this guy, who knows so much about dark energy and cosmology, know so little of religion that he does not even understand the definition of a miracle? Fortunately, some of the comments following this post did make the point:

It seems to me a little absurd to criticize scientist for not jumping on things like virging [sic] birth or walking on water. The whole point of these miracles is that they are, precisely, miracles. They are once in a lifetime occurances that take place by divine intervention. I don’t think science has anything to say about that: a non-reproducible, one time event that is by definition outside the natural realm. Evolution is an entirely different game, as it concerns the development of species in a natural way. It can (and has) been tested.

The other point I want to make about is all this is the irritating way atheists like Dawkins talk up the "inspirational" aspects of science and nature. Look at this from an interview with Dawkins:

QUESTION: Professor Dawkins, at the start of your talk, you said that the traditional religions were not only false but also failed to provide a deeper meaning than science and in that sense were not more soulful. I agree with that, to the extent that they attempt to provide an explanation, but another thing that the religions do is give comfort to people if they lose people in car accidents or to cancer and so on, and as far as I've experienced it, the scientific view cannot give people this kind of comfort. So in that sense the religions, even if they're false, are more soulful. And I wonder how you would respond to that.

Dawkins: ....although science may not be able to console you in the particular case of a bereavement from a car accident, it's not at all clear that science can't console you in other respects. So, for example, when we contemplate our own mortality, when we recognize that we're not here forever and that we're going to go into nothingness when we die, I find great consolation in the feeling that as long as I'm here I'm going to occupy my mind as fully as possible in understanding why I was ever born in the first place. And that seems to me to be consoling in another sense, perhaps a rather grander sense. It is of course somewhat depressing sometimes to feel that one can't go on understanding the universe; it would be nice to be able to be here in 500 years to see what people have discovered by then. But we do have the privilege of living in the 20th and very soon in the 21st century, when not only is more known than in any past century, but hugely more than in any past century. We are amazingly privileged to be living now, to be living in a time when the origin of the cosmos is getting close to being understood, the size of the universe is understood, the nature of life in a very large number of particulars is understood. This is a great privilege; to me it's an enormous consolation, and it's still a consolation even though it's for each one of us individually finite and going to come to an end. So I'm enormously grateful to be alive, and let me take up what Steve was talking about, the question of how you can bear to get up in the mornings. To me it makes it all the more worthwhile to get up in the mornings -- we haven't got that much time, let's get up in the morning and really use our brief time to understand why we're here and what it's all about. That to me is real consolation.

Or as Physicist Steven Weinberg has said:

...the more the universe seems comprehensible, the more it also seems pointless...

and:

Though aware that there is nothing in the universe that suggests any purpose for humanity, one way that we can find a purpose is to study the universe by the methods of science, without consoling ourselves with fairy tales about its future, or about our own.

Isn't this at heart an extremely elitist view? Fine if you are a scientist, or an autodidact, but what about people who don't have that intrinsic interest or the ability to learn much about, or contribute to, the advance of science?

Maybe it is easy to overstate the importance of religion in the West today, as apart from declining church numbers, we all know people who more or less successfully avoid the "big issues" for most of their lives. But Dawkins and his pals are keen to destroy even any subconscious level of optimism that people may have absorbed from religion (namely, that there is meaning and purpose to the universe, and each person is intrinsically valued not just because other humans deem it so, but because it is true at the transcendent level.)

An outbreak of common sense at The Guardian? (And I get to talk about airships)

If the figures in this article in the Guardian are correct, it really does make all the European panic about flying and greenhouse gases sound rather ridiculous:

UN scientists from the International Panel on Climate Change (IPCC) estimate aviation's contribution to global carbon emissions to be just 2%. To put things in perspective, road traffic contributes 18% globally, while the fossil fuels used to generate heat and power contribute 35%.

"But you are growing uncontrollably," is the usual retort. Our industry is growing at between 5 and 6% per year because people want to travel. The biggest growth is in rapidly developing economies, such as China, India and eastern Europe. Their hard-earned wealth is helping them to travel the world. This is balanced by slower growth in more mature markets. And the net impact - estimated by the IPCC - is that aviation's contribution may grow to 3% by 2050.

And further down:

...I am not arguing that aviation should be left alone to pollute as it sees fit. Consume less fuel and you emit less carbon. Aeroplane manufacturers understand. Over the past 40 years - starting long before Kyoto - fuel efficiency improved 70%. And the next generation of aircraft will have a fuel efficiency of just three litres per 100 passenger kilometres. That is much better than any hybrid car on the market.

Airlines have also understood. In the past two years, fuel efficiency has improved 5%. They are doing everything from making spoons lighter, to optimising the amount of water in toilets.

Our own association's efforts to straighten routes, reduce congestion and eliminate delays slashed carbon emissions by more than 12m tonnes in 2005 - equivalent to removing 3m cars from Britain's roads.

Damn. One of the cooler things I wanted to see come out of an anti greenhouse gas campaign was a return of the large scale passenger airship. Sounds like it is hardly necessary.

Of course, airships are inherently lovely anyway, and there always seems to be some company hoping to be about to revive the giant airship. Popular Mechanics ran this article recently about "hybrid airships" which are an interesting idea:

Hybrid airships use gas to generate 30 to 80 percent of the lift they need to get off the ground, and depend on aerodynamic lift--the flow of air over wings or fuselage--for the rest. That means that when hybrids stop moving through the air, they sink. The advantage? Once on the ground, they stay put. A major problem for conventional airships is the difficulty in handling them on the ground. Large and buoyant, they're always eager to fly away on the slightest breeze. The Goodyear blimp requires 17 handlers; the zeppelins of the '20s and '30s employed hundreds.

Defence in the US had paid money (under its nicely named but defunct "Walrus" program) to investigate these heavy lift airship-ish things, but whether a large scale one will ever be built seems unclear. Companies that like to talk up airships often come up with nice graphics and concept illustrations. Aeros Corporation's is worth looking at.

The PM article, and this website, talk about hybrid airships with a load capacity of up to 500 tons. How that compare to airplanes? According to this article, a new variant of the 747 will carry 154 tons of freight. A 500 ton capacity Walrus derived airship could therefore presumably carry a lot of people. I guess you would only need build one a fraction of that size.

I would have thought that their use around Europe would have been most appropriate. The distances make for more reasonable travel times, with lots of nice scenery to look at .

An interesting snippet

From the PM's commission's report on the feasibility of nuclear power in Australia:

Compared with other non-combustion
technologies, such as solar and wind power,
nuclear power requires a much smaller footprint
for equivalent power generation. A current 900 MW
nuclear power plant, with a footprint of less than
1 km2, would produce as much electricity in a year
as 70 km2 of solar photovoltaic panels, or about
1000 wind turbines, taking into account the
efficiencies, availabilities and capacity factors.

If it's good for the goose ...

If these Imams had read my earlier post here, they would know that demonstrative praying on airplanes is just not a way to make your fellow passengers feel relaxed and comfortable. (My post in September was about a Jewish fellow who was asked to leave an airplane for praying while seated and "lurching back and forth" in the Jewish manner. By the way, is there a reason for that custom?)

The Imams style of prayer was a little more obvious:

Three of them stood and said their normal evening prayers together on the plane, as 1.7 billion Muslims around the world do every day, Shahin said. He attributed any concerns by passengers or crew to ignorance about Islam.

Well I assume those 1.7 billion don't include people like pilots on final approach to landing. There is an exemption allowed for not being in an appropriate situation to say your prayers openly, isn't there?

The 6 Imams were asked to leave:

A passenger initially raised concerns about the group through a note passed to a flight attendant, according to Andrea Rader, a spokeswoman for US Airways. She said police were called after the captain and airport security workers asked the men to leave the plane and the men refused.

Maybe, for the hard of learning, airports need to put large signs at boarding gates: "Kindly refrain from praying in an obvious manner while on board the aircraft, to ensure there are no misunderstandings, delays or arrests."

Hitchens on Baker

Hitchen's latest article in Slate hits out at the rise of James Baker and "realism" as the possible solution to the Iraq problem. On the idea of negotiating with Syria and Iran, Hitchens makes the valid enough point:

Given that these two regimes have recently succeeded in destroying the other most hopeful democratic experiment in the region—the brief emergence of a self-determined Lebanon that was free of foreign occupation—and are busily engaged in promoting their own version of sectarian mayhem there, through the trusty medium of Hezbollah, it looks as if a distinctly unsentimental process is under way.

This will present few difficulties to Baker, who supported the Syrian near-annexation of Lebanon. In order to recruit the Baathist regime of Hafez Assad to his coalition of the cynical against Saddam in the Kuwait war, Baker and Bush senior both acquiesced in the obliteration of Lebanese sovereignty. "I believe in talking to your enemies," said Baker last month—invoking what is certainly a principle of diplomacy. In this instance, however, it will surely seem to him to be more like talking to old friends—who just happen to be supplying the sinews of war to those who kill American soldiers and Iraqi civilians. Is it likely that they will stop doing this once they become convinced that an American withdrawal is only a matter of time?

It's also hard for America to deal with Iran when its nutty president (Iran's I mean!) is feeling so cock-a-hoop about appearing to have the US over a barrel with regard to its nuclear program.

UPDATE: Kind of unusual to find the New Yorker running a commentary piece that is in complete agreement with Hitchen's take on Iraq. But there it is.

Breathe deeply

Just an interesting short article in New Scientist:

Alzheimer's disease has a range of disparate risk factors, but researchers may now have found one underlying cause that links them all: a lack of oxygen.

Previous studies have shown that diabetes, stroke, clogged arteries and ageing all increase the risk of developing Alzheimer’s. Only 5% of cases appear to have been strongly influenced by genetic factors. Now evidence has emerged that lack of oxygen may be the ultimate cause.

Weihong Song at the University of British Columbia in Vancouver, Canada, and colleagues took mice engineered to develop Alzheimer’s-like plaques and put them in a hypoxia chamber, which limits the amount of available oxygen. For 16 hours per day, for one month, the mice received less than 40% of the oxygen they normally use.

Six months later, the oxygen-deprived mice had developed twice as many beta-amyloid plaques – the hallmark of Alzheimer’s disease – compared with similar mice kept in normal conditions. The hypoxic mice also performed worse on memory tests.

I guess it would account for why exercise helps prevent it too?
