Over-dedication to a career path

Well, I don't think I had heard before that the Captain of the whaling ship which was sunk by a sperm whale (and inspired Moby Dick) then went on to float around the Pacific with some other survivors for 3 harrowing months, ate his cousin to survive, was rescued, got taken back to Nantucket, then went back to sea as captain of the rescuing ship. Only to have it sink too.

The New York Times adds some further details.

Three Science Stories

1. Comforting, probably almost:

Apophis asteroid will probably almost certainly not smash into Earth, say scientists

2. Australian scientist working on a "thinking cap". (Probably more correctly called a "creativity cap".) I heard this guy being interviewed on the radio, and it certainly sounds interesting. This report is a bit light on details, so I must look around for more.

3. The US has been bit hit by a lot of snow lately, but was the January just gone any record for it being a cold month? Nope, apparently not:
Last month was the coolest January since 1994, according to scientists at NOAA’s National Climatic Data Center (NCDC) in Asheville, N.C. Across the contiguous United States, the average January temperature was 30.0 F, which is 0.8 F below the 1901-2000 average. And despite several large winter storms across the country, last month was the ninth driest January on record, much drier than normal.

Spider lost

Wow. That Spider-man stage show really sounds very, very strange. Full details at Slate.

More links to bad reviews at Salon.

Maybe they were going for the Springtime for Hitler effect?

Greene on film

I see there's a new film version of Graham Greene's Brighton Rock, but it's apparently had so-so reviews. (It also changes the setting of the film to the 1960's.)

I think I've noted here before that I found the novel very psychologically unconvincing in its portrayal of Pinkie, the amoral protagonist. The woman who tracks him down (I forget her name now) was written much better.

In any event, the reason for the post is to note that I'm currently reading The Quiet American, and it certainly seems to show him as a better, more mature writer. However, a couple of weeks ago the film version of the novel (the recent one with Michael Caine and Brendan Fraser in the lead roles) was on TV and I decided to at least watch the start and see how well it reflected my mental image of the novel.

My immediate impression was that the Michael Caine character look far too cheery and not world weary, jaded and cynical enough. It's virtually impossible to act too glum to reflect a Greene main character, and Cain looked far too contented. Brendan Fraser looked better in his role. The movie also looked a tad too "pretty" compared to images I had of the settings in the novel. But I only watched the first 15 minutes or so, so perhaps it became more appropriately sordid later.

It's been a long time since I saw The Third Man, but I remember being rather under-whelmed by that too, despite its reputation. I just doubt that Greene translates well to the screen, probably because it's hard to get all that internal mental anguish up there for everyone to see.

The other thing about reading Greene that I've realised is that, being the subject of extensive biographies which have covered his, shall we say, bad habits in extensive detail*, and the fact that his autobiography explains how he had a compulsion to try new experiences (even playing to the extent of playing Russian roulette) to make himself feel "alive," whenever a character in his novels is doing something seedy, one immediately has the impression that Greene must be talking about it from personal experience. Thus, in one novel where a character goes to an African prostitute, or (in The Quiet American) uses opium, you can't help but feel you're reading a vignette from Greene's own life.

Maybe that's not always right, but he certainly was a complicated character (caused no doubt at least partly by bipolar disorder.) Not sure that I would ever embark on a biography about him though.

* I trust no one has forgotten this extract from a review of a book about him I posted a few years ago:
Greene as sex addict does not figure strongly in these letters. But in his exhaustive (and, at 2251 pages, exhausting) authorised biography of Greene, Norman Sherry annexes a list of 47 favourite prostitutes scribbled down by Greene in 1948 when his mistress Catherine Walston challenged him about rumours that he paid women for sex.

What I've been doing

Work and money continues to be a major distraction, but I wanted to note:

* Bad weather, part 1: It's a pretty "good" season for extreme weather that may encourage belief in climate change and political action on carbon emissions. So much so that Andrew Bolt seemed to have a fleeting moment of doubt last Friday (hinting that the heavy storms in Melbourne and Victoria, on top of the already unusual slow moving Victorian floods, really are "freaky"), but then he obviously had the strong urge to crush any hint of self doubt by a flurry of anti climate change posts over the weekend. I'm not going to link to them; he's an unthinking promoter of every bad argument against sensible precaution, and it's the political influence I'm sure he wields on the grass roots of the Coalition that makes him not a joke on the issue.

* Bad weather, part 2: Watching Cyclone Yasi coverage last week really made me a little sorry for journalists who were in the wrong spot (Cairns) for any interesting footage of the approaching storm. It is, in any event, impossible to get good footage of a really bad cyclone, given that no one sensible should be on the street, or even close to the windows, but the media seems not to have realised this yet. Skynew's coverage on the night of the storm was particularly ludicrous, with what seemed an hour of live footage of some smallish palm trees and shrubs being blown about in a motel room courtyard in Bowen being the best they could come up with.

Then, in the morning, it felt a bit anti climatic, given that the media still couldn't get into the worst affected areas.

But I thought the best cyclone damage footage to come out a couple of days later was from the Dunk Island resort. It's hard to imagine how long it will take to look good again, and you don't often see that many denuded trees in one place.



Oddly enough, you'll also find that the first comment following this on Youtube is by a guy who says the resort deserved it because the owner tried to hit on his 17 year old daughter during a recent bad holiday! Just a tad defamatory, I would have thought, and doesn't Youtube exercise any control over its comments section?

* Bad weather, part 3: I've had a couple of interesting conversations with people affected by the Brisbane flood. One was with the manager of a nice, new block of apartments facing the river on Coronation Drive. These are obviously built with an awareness that the underground car park can flood in a 1 in 100 flood, but the units are above the flood level. The problem is, they still put the electrical power for these buildings in the car park levels too, meaning the block was without power for 2 weeks, and even now that it is back on, the lifts are still awaiting repair! Given that it is about 8 to 10 stories high, (as are many on that stretch of Coronation Drive), this seems an issue which one would have thought the designers (and Council) should think about more carefully.

The second conversation was with a woman who has (or had) a nice house on the Brisbane river. She has lost retaining walls and is worried about pool subsidence, as well as the issue of what to do with a metre or so of mud in her backyard which might be (temporarily) helping to keep the pool in place. Apparently, the Council is suggesting she has to get rid of the mud, but they don't want it back in the river either. This remains an unresolved issue.

* In praise of animation: I saw Tangled, the Disney animated flick (and said to be the last of their "Princess" movies) and was very impressed. There is one sequence which plays so beautifully, I am not ashamed to say it brought a tear to my eye.

I am not alone in this, even amongst males. (I read - but have lost the link to - some blog review by an American father who said the same; but of course, he might be a big girlie man too.) It is, in a way, surprising that animation can move anyone to tears. But David Byrne had something interesting to say about this a few years ago:

Malu and I went to see The Incredibles, the new Pixar film about disgruntled retired superheroes. I laughed and cried, as I do at lots of animated movies. I wonder if I get more emotionally involved in animated characters than in films using real actors? Other than Spielberg movies that deliberately work the sentimental buttons it's much easier to identify with drawings than with real people.

Maybe this isn't strange. Maybe the fact that they're drawings makes them more ambiguous, more universal, and easier to identify with. Well, it's true with lots of other things — things that use metaphor, allegory and poetic ambiguity are generally more powerful emotionally than straight narrative.

I find myself increasingly in awe of animation lately, and the creativity that goes behind it. This comes from watching the "making of" documentaries that come on DVD's. I re-watched two severely under-rated and under-performing recent animated movies over Christmas (Astroboy, and The Tale of Despereaux,) and watching the documentaries after it just made me appreciate how much thought goes into creating animated worlds.

I suppose you could argue that art direction in any fantasy live action movie also plays a key role that is not often thought about by your average viewer; but with animation, the page is blank and is unaffected by the availability of locations that need to be dressed up. It is, in that sense, arguably the most artistically creative movie medium of all.

But not all animated movies grab me. Despicable Me seems to have done very well at the box office, but when I finally caught up with it on DVD, I found it very flat and not engaging at all.

* Avoiding the discussion: In a move sure to attract some amused comment, I've been busy creating a short, age appropriate, slide show movie with a sex education theme for my son. This is really very time consuming, as all the drawings are being done on my iPad and then transferred to the desktop for compilation. Use a bit of Midi music as the soundtrack, and occasional bits of computer generated voice, and it should all be finished in a week.

My wife knows of the project, and like (I'm sure) everyone else who will hear about it, considers this somewhat eccentric. However, as it is "men's work", she seems not so interested to see it.

This is really the result of not being able to find anything I consider appropriate in tone or content on the internet - which seems to me to be quite surprising, given what you can find on it. [There is a Victorian kid's sex education site, that is clearly designed for kids of about my son's age, but if every link is followed, it's really a case of more information than I feel he needs now. Also, the cartoony look is pretty ugly, and some of the illustrations are of outright questionable merit - one page shows a bunch of cartoon girls using mirrors to check themselves out.(!) I think The Vagina Monologues have got a lot answer for.]

The basic idea is for a short "what to expect from your body within the next year or two", and that does involve some discussion of internal plumbing and understanding of the basics of sexual reproduction. I've thrown in a bit of evolution too; why plants and animals share bits of each other in reproductions seems a sort of basic point to me. But all the issues of when to have sex, etc; that can wait til a bit older, if you ask me. I had better start on that Part 2 soon, though.

As a friend said to me on the weekend, "why not just talk about it?" Well yes, of course, I'll invite questions at the end of the show. Whether or not I'll be in the room to answer them, though, is a different matter. :)

Things to do

It's hard lately to both concentrate on work and survey the web for stuff that interests me and is "blogworthy." Also, the tax department, oddly, does not seem to appreciate the need to be the most reasonable person to comment at a certain "centre right" blog as a reason for delaying payments.

So I have to abandon it all for a week at least, until I can spot where money is coming from again.

My faithful readers can tell me what I have missed in comments section. As I know from when I have been on holidays, it only takes a relatively short time to catch up on favourite blogs when one has been away for a couple of weeks in any event.

This time, I mean it. Away from the web for me.

Watching the war

SBS has, for a long time, been the place to go to watch documentaries about World War 2, particularly on Friday nights.

As it happens, I don't really care for the current series "Apocalypse - The Second World War" because it's one of those with a hysterical sounding narration*, and a gruesomely high body count that makes it unsuitable to watch with my son. (He really likes history, inspired by the Horrible History series of books, and probably already retains more knowledge about certain periods of British history than I can recall. He is usually happy to watch any documentary about war that's on.)

But the reason for mentioning this is to note that SBS2 has also been showing a lot of WWII documentaries. They are not new, and may well have been on SBS1 years ago, but I've been happy to catch up with them anyway.

This week, there was one that was just about the Japanese surrender at the end of the war, and featured as its most lengthy section footage of MacArthur and the other Allies signing the surrender instrument with the Japanese on the USS Missouri. It was a fascinating minor detail of history to learn about the mistake made by the Canadian representative (who signed on the wrong line, which meant those below him also did.) There was then a bit of a agitated discussion with the Japanese as to whether they would accept the document signed this way. It was amended by hand and initialled. The Wikipedia entry about the document is here.

Another recent SBS2 doco from a few years ago was about the Nazi's attempt to get heavy water to Germany to conduct research into an atomic bomb. It included an expedition to retrieve a barrel from the boat (which had been sunk by the allied operatives) to double check whether the Nazis had actually sent a decoy barrel. (Turns out they didn't.)

Anyhow, this is just a pointer to anyone in Australia looking for interesting stuff on TV. Don't overlook SBS2.


* yes, I know, hysteria may be an appropriate response to certain things that happened then, but it still puts me off in narration. But they do show many scenes of death which are disturbing to say the least. Last week, they dealt briefly with Jews being killed in Russia, and showed some film of this incident:
The most notorious one – perhaps one of the single most infamous events of World War II – was the execution of more than 33,000 Jews from Ukraine’s capital Kiev, at the ravine of Babi Yar on 29-30 November 1941.
Such stuff still has the capacity to make me feel sick.

Getting your fears in correct priority

According to this Scientific American blog, in an 8 year recent period in the United States, more spiders killed people than snakes. I wouldn’t have picked that.

But then, 9 people died of alligator or crocodile attack. Who knew cleaning New York stormwater drains could be so dangerous.*

But amongst deadly venomous animals, bees and wasps come out as far the most important: 71% of such deaths.

Which raises an interesting point: when I was a kid, we used to get clover (the type with the white flowers) growing in the yard or on the footpath, and it was very attractive to bees when it was in bloom. This meant that walking barefoot on it was a pretty easy way to get a bee sting, and I certainly had a few as a youngster. (Although I’m pretty sure one was from trying to catch a bee in a jar.)

These days, though, it seems kids are much, much less likely to get a bee sting as an ordinary part of growing up. (I just don't notice clover around much anymore, and even if it is in someone's yard, the kids are probably inside on the computer.) This, I am guessing, makes it much more of a worry that any allergy to bees may not be known until they are much older.

I suppose that, ideally, you never find out you have the allergy. But somehow it seems to me to be safer to know you have it when you’re younger, rather than having a sudden unexpected medical crisis as an adult.

* I may have invented that detail.

Climate stuff noted

First, the New York Times has a good, balanced article on the question of the cold European and American winters this year and last, and whether it can reliably said to be all part of global warming. (The answer is: a definite maybe, but we need to do more research.)

In case you haven't heard, as with last winter, the far north of Canada has been remarkably warm:
Yet while people in Atlanta learn to shovel snow, the weather 2,000 miles to the north has been freakishly warm the past two winters. Throughout northeastern Canada and Greenland, temperatures in December ran as much as 15 to 20 degrees Fahrenheit above normal. Bays and lakes have been slow to freeze; ice fishing, hunting and trade routes have been disrupted.

Iqaluit, the capital of the remote Canadian territory of Nunavut, had to cancel its New Year’s snowmobile parade. David Ell, the deputy mayor, said that people in the region had been looking with envy at snowbound American and European cities. “People are saying, ‘That’s where all our snow is going!’ ” he said.

It's interesting to see scientists openly acknowledging that they need to be cautious in what they say:

In interviews, several scientists recalled that in the decade ending in the mid-1990s, the polar vortex seemed to be strengthening, not weakening, producing mild winters in the eastern United States and western Europe.

At the time, some climate scientists wrote papers attributing that change to global warming. Newspapers, including this one, printed laments for winter lost. But soon after, the apparent trend went away, an experience that has made many researchers more cautious.

John M. Wallace, an atmospheric scientist at the University of Washington, wrote some of the earlier papers. This time around, he said, it will take a lot of evidence to convince him that a few harsh winters in London or Washington have anything to do with global warming.

This is fair enough, but given the way climate change skeptics will use any cold snap to bolster their case, it's important that articles at least talk about the possible mechanisms by which the winter weather may indeed be consistent with AGW.

Second: there are a few climate change blogs I've started reading more regularly lately, and I've added them to the blogroll. AGW Observer, being run by a Ari in Finland, seems a particularly useful collection of just published papers on climate change. I hope he keeps it going.

I've also been enjoying Michael Tobis, even though he seems to be getting pretty desperately pessimistic, and Tamino is always good to check on despite his not too frequent posts.

Funny, I can't find any climate change skeptic blog worth adding. Watts Up With That can be trusted to bring any new skeptic claim to light, anyway.

Third: early figures comparing Brisbane's last two floods show that 1974 Brisbane floods were indeed based on a lot of rain:

But weather experts suggested "peak rainfalls from the 1974 event were substantially heavier than those in 2011".

Brisbane's three-days and one-day totals were 600mm and 314mm in 1974, compared with 166mm and 110mm in 2011.

"However, in 1974 the heaviest rains were closer to the coast whereas in 2011 heavy rains spread further inland," the bureau said.

The bureau is still crunching the numbers, and it will be interesting to see if the widespread nature of the 2010/11 floods is unusual in Queensland history. Certainly, I don't recall flooding all the way from Brisbane to Rockhampton and far inland in such a short period before; but I don't exactly keep precipitation charts on my bedroom wall.

Of minor blogworthiness

Nothing much around that makes me feel like posting at length today, although people might be curious enough to read these:

* the odd problem of "fake" love hotels in Japan. Funny, I thought town planning was a concept unknown to the Japanese, but they do actually stop love hotels from being less than 200 m from a school.

* Real Climate has a good post updating the comparisons of climate models with actual observations. Result: there is no great crisis in climate science according to these comparisons, although of course it remains a complicated field.

* I missed this from December: the Billfish Foundation (great name) and NOAA say that these big fish (including tuna) are having less ocean to stay in because of increasing hypoxic areas:

While these hypoxic zones occur naturally in many areas of the world’s tropical and equatorial oceans, scientists are concerned because these zones are expanding and occurring closer to the sea surface, and are expected to continue to grow as sea temperatures rise.

“The hypoxic zone off West Africa, which covers virtually all the equatorial waters in the Atlantic Ocean, is roughly the size of the continental United States, and it’s growing,” said Dr. Eric D. Prince, NOAA’s Fisheries Service research fishery biologist. “With the current cycle of climate change and accelerated global warming, we expect the size of this zone to increase, further reducing the available habitat for these fish.”

* You probably already heard, but I'll note it here anyway: one paper last week says that climate modelling has underestimated the effect of loss of ice and snow on future temperature rises. Great...

* Did I mention this before? I don't think so, I think I intended to: it's a steam bath, but not as you know it.

There you go. Not all of that of what "minor blogworthiness" after all.

Now I should work today, as it's a holiday tomorrow.

All summer in a day*

Yesterday was a lovely summer's day in Brisbane; the first in 3 months it seems. So, being the last day of the school holidays, we went down to the Gold Coast and had a nice time at the beach. Water temperature was warm; no bluebottles; the sun was out but the air did not feel too hot. Lovely.

As for recent Queensland weather generally, I note that Andrew Bolt had quoted another blogger claiming that a report by Queensland's Office of Climate Change barely mentioned "floods". It turns out that this relates to merely one chapter of the report, and as Tim Lambert says, it's another case of climate change skeptic gullibility.

In terms of the climate change debate, I have never paid all that much attention to the particular regional rainfall changes for Australia forecast by CSIRO and the like. I just always assumed that regional forecasts under climate models were going to be more rubbery than the general effect of increased heat waves, which I consider a big enough worry. This explains why I wasn't really aware that there had been predictions of both extended droughts and intense rainfall under AGW. But as Tim Lambert notes, the report Bolt tries to slur as being warmenist propaganda that puts the emphasis all on drought, has this:
Climate change is also likely to affect extreme rainfall in south-east Queensland (Abbs et al. 2007). Projections indicate an increase in two-hour, 24-hour and 72-hour extreme rainfall events for large areas of south-east Queensland, especially in the McPherson and Great Dividing ranges, west of Brisbane and the Gold Coast. For example, Abbs et al. (2007) found that under the A2 emissions scenario, extreme rainfall intensity averaged over the Gold Coast sub-region is projected to increase by 48 per cent for a two-hour event, 16 per cent for a 24-hour event and 14 per cent for a 72-hour event by 2070. Therefore despite a projected decrease in rainfall across most of Queensland, the projected increase in rainfall intensity could result in more flooding events.
Very prescient, as it turns out. (Not to say that you can directly attribute any particular extreme weather event to AGW yet.)

Last week, I pointed out a different paper which indicated the same thing (modelling indicates longer droughts but broken by intense rain) at Catallaxy, a.k.a the "centre right" blog where climate science goes to die. This was followed by the glib "so, everything's consistent with AGW" response that shows that even though a weather event may (after all) be consistent with climate modelling of some years ago, they will insist on claiming that it either isn't, or that it doesn't matter.

I think that Tim Flannery's role as a populariser of AGW has something to do with this, in that he seemed to love making statements that gave the impression that Australian cities were facing pretty much continual drought since the last one started about a decade ago. But again, I simply haven't paid him much attention, and skeptics who harp on about him are in one sense fighting a straw man.

Meanwhile, a fight has broken out at Judith Curry's blog about attributing extreme weather to AGW, and the Queensland floods get a particular going over. (Read from here down). Curry did do one thing useful, and linked to this site, which has a lot of links to papers over the years looking at extreme rainfall over the decades in Australia.

Andrew Bolt's also been an enthusiastic promoter of the idea that poor management of the water flows out of the Wivenhoe dam was the real cause of this flood. He is following the lead of The Australian's Hedley Thomas, who has been running a story kicked off by an engineer with no experience in hydrology, although others (not directly involved in Wivenhoe) have come out offering some sort of support. Of course, now that an enquiry is underway, the proper thing to do is to give it a rest. I personally expect that there will ultimately be no blame put on the Wivenhoe dam managers at all, nor on any politician. One media report noted last week that the dam inflows that led to the floods were enough to fill it in a day (something I would not have thought possible.) I simply find it very hard to believe that in those circumstances it is at all likely that the outflow decisions could have done anything other than make a very minor difference to the flood height.

However, if I worked for SEQ Water, I would consider both Hedley Thomas journalistic campaign, and Bolt's anti climate change politicisation of it, to both be offensive smear campaigns. No, wait: I don't need to work for SEQ Water to be very annoyed with Bolt's line of argument. (Sure, you can say that I've already admitted that I didn't have knowledge of the drought and flood AGW papers either, but then I'm not the one running an anti climate science campaign in a national newspaper, and being completely careless of informing myself about facts.) Bolt is running not just with the line that the dam operators were at fault, but it was the insidious effects of "warmenism" that led them to not let out enough water in case we were left without enough drinking water. Oddly enough, while Bolt was saying this, John Quiggin quickly shot from the hip and suggested that maybe the dam should be operated at 75% capacity when a wet summer is forecast. While I expect Quiggin may well change his mind, it certainly shows there is at least one "warmenist" who takes a line contrary to what Bolt would suggest.

I bet the reality turns out to be this: the dam has always been intended to run at 100% supply for drinking water if possible, and population increases since it started operating in 1985, and a recent drought which led to the dam getting dangerously low meant the policy continued to make a lot of sense. "Warmenism" will have nothing to do with the policy existing to this day.

We'll see if I am right or wrong.



* I knew the title was from a science fiction story, but I couldn't remember anything about it. Turns out it was particularly apt:
The story is about a class of school children on Venus, which in this tale is a jungle world of constant torrential rainstorms, where the sun is only visible for only two hours every seven years. Such an occurrence is imminent.

Meanwhile, in a cylinder in Russia…

How easy it is to forget about the international team of Claustrophobics Anonymous which has been living in a can near Moscow for 6 months already on a pretend mission to Mars.  But they are approaching “landing”:

 The six men are due to "land" on Mars on Feb. 12 and spend two days researching the planet. They then begin the months-long return flight to Earth, expected to be the most challenging part of the mission.

How do you explore Mars for two days?  I’m glad you asked:

In an effort to reproduce the conditions of space travel, with exception of weightlessness, the crew has living quarters the size of a bus connected with several other modules for experiments and exercise. A separate built-in imitator of the Red Planet's surface is attached for the mock landing.

Well, two days may well be enough after all.

Does this project have its own website?  Indeed it does, although for me it loads at about 1979 internet speeds, but hey, it is Russia.  It would also appear that wood veneer is very popular in Russian Mars spaceships, from the one photo I can see.   There is also a link to a blog that seems to only be in Russian.  But it does contain a photo of the simulated Mars surface.  Yes, I think they will cover all the sights well within 2 days.  I hope they are not disappointed.

Lessons for my daughter

Oh good. An article in the Japan Times that covers my interest in both Japanese toilets and theology: Paying respect to the Japanese toilet god.

Amongst other things, it notes that there was a popular folky song in Japan last year - "The Toilet God":
The lyrics were inspired by the singer's grandmother, who held that women should clean toilets in order to honor the beautiful female deity presiding there. My own grandmother used to say that daughters who cleaned the family toilet were destined to become beautiful, and would in turn bear beautiful daughters.
I must admit, my daughter already finds cleaning a toilet an entertaining past time. My son - not so much.

The article also notes Japanese toilet folklore:

Anyone who has been through the school system here has the old stand-by: toire no Hanako-san (トイレの花子さん, Hanako in the toilet stall), the ghost of a girl who died mysteriously — usually bullied by classmates and locked into a smelly toilet — who has come back to haunt her old grade school.

The older generation, who grew up in rural Japan, may come out with some pretty macabre stuff. One that's practically legend is the story of the village brute who crawled into the compost tank of the local girls' school and mired himself there for weeks, only to be discovered when an inquisitive student peered into the creepy darkness of the washiki benki (和式便器, Japanese crouch-style toilet bowl) and saw a pair of eyes looking up at her.

A bit more impressive than redbacks on the toilet seat.

A whole bunch of physics (expanded from yesterday edition)

Just when I was thinking "gee, there hasn't been much speculative physics stories around for a while", I find a whole bunch of blogworthy material in one session:

* a couple of University of Queensland guys talk about how quantum entanglement can not just be across space, but across time as well. The crux of what this means is summed up here ( I hope accurately):
Olson and Ralph's teleportation provides a shortcut into the future. What they're saying is that it's possible to travel into the future without being present during the time in between.
Cool. Not dissimilar to a really good night's sleep, though.

* Physics World has a good article looking the LHC after a year, and what it has shown so far, and may yet show. It includes this bit about mini black holes:
CMS scientists have also found no evidence for micro black holes in their 12,500 tonne detector (arXiv:1012.3375). This result, reported just before Christmas, will not have come as a shock to anyone who thinks such black holes will destroy the planet. (For them, it's only a matter of time...) But it has not surprised many physicists either, given that miniature black holes could only appear at the LHC if space has more than three dimensions. So what does CMS's black-hole blank mean for such outlandish pictures of space–time? Can we now simply start ruling them out?

"The fascinating science of black-hole production and evaporation still stands," insists Steve Giddings of the University of California, Santa Barbara, who a decade ago co-proposed the possibility that the LHC might create black holes. "The CMS results begin to rule out the most extreme configurations of extra dimensions, although it is true that such configurations are believed unlikely by many. It's still a possibility that black holes will be made at the LHC, but it's not a prediction unless you know the configuration of the extra dimensions!"
The rest of the article, which mentions string theory and whether or not it can in any respect be bolstered by future findings, is worth reading.

* Physics World has another good article up: a review of a book of essays called Information and the Nature of Reality: From Physics to Metaphysics. Who can resist that?

As the title suggests, the essays get to theology eventually:
The problem, of course, is that once we leave the scientific domain, it becomes rather easy to make unfounded speculations about the connections between information and various other religious concepts. For instance, in the last chapter of this book we encounter suggestions that the Christian Gospel of John could be interpreted in information-theoretic terms. Similar parallels are drawn in the essay by Michael Welker, who discusses the information content in the resurrection of the Christ. Carelessly extrapolated, this sort of exposition might lead to arguments similar to Frank Tipler's nonsensical "proofs" of various Christian dogmas in his two books The Physics of Immortality and The Physics of Christianity. Amusing as such parallels might be, it is doubtful that they will ever lead to any greater enlightenment as to the nature of reality itself.
Speaking of information and the gospels, I remember a conversation I once had with a Catholic quasi-girlfriend (I'm not sure we ever quite agreed on her status) in which I complained that, if God wanted Jesus to be seen as convincingly divine 2000 years after he trod the Earth, it would have been handy to have some bits of science thrown in the Gospels, like this: "Consider the water. Little do you know that the air you breath has the essential parts that, when joined together, two parts to one, make the water that will quench your thirst." Of course, the possibility is that Jesus did make references to science all the time, but the Gospel writers found them so silly or incomprehensible that they refused to commit them to paper. Or it may be that something like advanced games theory means it's really quite important for humanity not to have the certainty of God or an afterlife staring them in the face all the time. The temptation to keep killing others for perceived wrongs and let God sort it out on the other side might be too much. There are no doubt other theories around.

* Don Page, a Christian physicist who I have mentioned before, has a new article out arguing against the universe we find ourselves in being fine tuned for life. As Bee Hossenfelder notes, Don uses this argument as support for his fondness for a multiverse, ending his paper this way:
"It could be taken as negative evidence for theists who expect God to fine tune the constants of physics optimally for life. However, for other theists, such as myself, it may simply support the hypothesis that God might prefer a multiverse as the most elegant way to create life and the other purposes He has for His Creation."
By the way, physicist Bee's own universe has expanded lately by the birth of twins. Congratulations are in order.

We think we've found the problem

In Australia, a news story about the how often the population is having sex will more than likely be based on some women's or men's magazine unreliable reader survey.

In Japan, however, the government appears interested enough in its citizens to conduct the research itself. (Presumably, because of its soon to be rapidly declining population.)

So, what does the latest survey reveal?:
One-third of Japanese men aged 16 to 19 were uninterested in or even averse to sex as of last year, double the number from 2008, a government survey showed Wednesday.
Well, one suspects that this is misleading, unless the survey specified that "sex" means "with another person."

Anyhow, the interpretation of this is given as follows:

‘‘The survey result confirmed that young men have become ‘herbivorous’,’’ said Kunio Kitamura, head of the Clinic of the Japan Family Planning Association who took part in the survey, using the term used increasingly in Japan to describe young males who are shy and passive in relationships with women.

According to the ministry, 35.1% of men aged 16 to 19 said they are uninterested in or averse to sex, surging from 17.5% in the previous poll in 2008.

The percentage climbed to 21.5% among men aged 20 to 24 from 11.8% two years earlier, and among women of any age group, the survey showed.

Those married men and women who said they had no sex in the past month totaled 40.8%, up from 36.5% in the previous survey and 31.9% in a 2004 study.

As for the broader relevance of this: I read recently that Japan, Korea and Taiwan were amongst the lowest birthrate countries in the world. I'm pretty sure they all have very fast and pretty cheap internet access. Has anyone done the research into fast internet access and birthrates across the world??*

Any proper evaluation into Australia's National Broadband Network clearly should consider its population effects in 25 years time.

* I guess fast internet is unlikely to be the explanation for Russia's birthrate, but fast vodka may well have something to do with it.

Victorian murder

As noted in Arts & Letters Daily, there's an amusing review in the Spectator of a book about Victorian England's cultural enthusiasm for murder as a virtual entertainment. It puts our current TV obsession with all things criminal and forensic into perspective. I liked this bit about journalism of that period:

Anyone who thinks the 21st-century tabloid represents some sort of journalistic nadir, for instance, will find this book a bracing corrective. On the contrary, we live, it turns out, in a hitherto unexampled golden age of truthfulness and integrity.

Even proper 19th-century newspapers seethed with class bigotry, and routinely printed rumour as fact without thought to prejudicing a trial. What are now called ‘backgrounders’ would report that the accused robbed corpses in battle, spent his childhood torturing dogs, or had ‘been known to twist a whipcord round a horse’s tongue, and tear it out by the root’.

If facts weren’t available, they’d be invented. The Morning Chronicle, Jackson’s Oxford Journal, John Bull and the Bristol Mercury all reported solemnly that Mary Ann Milner had ‘conducted herself with much composure’ at her execution. This stretched plausibility, considering she’d committed suicide in her cell the night before. Even the illustrations were, more often than not, stock images appended at random: the purported likeness of one murderer, it was pointed out, was actually a portrait of William IV.

In terms of modern journalism, I would say that the Times of India has not entirely shaken off the Victorian template. Detailed background of a death or crime (such as the family dispute that led to it) are frequently reported in a way that is not common in Australia now. Let's see if I can find a current example. Here we go: look at the amount of detail that goes into this (alleged) rape report. The accused getting a fair trial after such publicity seemingly is of no concern in the country.

A good thing to avoid

Just file this under "things I didn't know" (or perhaps more likely, "something I had once read but forgotten"):
Women who have had chlamydia are at greater risk of an ectopic pregnancy because of a lasting effect of the infection. A new study provides evidence for the first time of how chlamydia can increase the risk of an ectopic pregnancy .
And just how "popular" is this disease? According to a report just a few days ago, quite:

Sexual health experts are demanding the Federal Government urgently fund a national screening program for chlamydia after figures showing infection rates have more than tripled in 10 years.
More than 61,000 people were diagnosed last year, up from about 17,000 in 2000. About 14,500 were diagnosed in NSW alone, the second highest rate in Australia.
More than half those infected were aged 20 to 29 and a quarter were aged under 19.

Not a flood post

A few things that have come to my attention:

* Richard Ayoade (Moss in the IT Crowd) seems to genuinely be a self-effacing, likeable person in real life. With a funny voice.

* Falling pregnant in zero gravity may well be difficult, and not good for the embryo if achieved, reports New Scientist:
What does seem clear is that space travel affects reproduction. Joseph Tash, a reproductive biologist at the University of Kansas Medical Center in Kansas City, examined 16 female mice that travelled aboard NASA's STS-131 mission last year. He found that the mice had shrunken ovaries, dying ovarian follicles and down-regulated oestrogen genes. Their reproductive systems "had shut down", he says.
This is dangerous news: I can see that space based teenage boys will use this as an excuse with their space based girlfriends not to use condoms.

* In other vital space news, it turns out that radishes, and even lettuce, do very well even after being exposed to near vacuum for 30 minutes:
After the team returned the pressure to normal, all the plants continued to grow until being harvested a week later. The plants appeared to be just as healthy as another set of plants never exposed to low pressure, with no significant difference in weight
If only Dave had a radish that could turn off HAL, 2001 could have ended very differently.

* I've started watching American sitcom The Middle. It's quite likeable, I think, even if not necessarily a laugh a minute.

Around the flood

This is how the week developed since my last post on Wednesday morning. (Feels longer ago than that, but experiencing novel events has that effect.)

There were plenty of warnings on Tuesday evening that the Brisbane flood could be very big – equal to, or even slightly higher, than the 1974 flood. However, since I had been told by long term residents that the group of shops in which my office is located had only taken water up to the car park (which rises about 1 – 2 meters above the street level) in 1974, I wasn’t too anxious. Indeed, the Council flood maps on the internet that evening indicated that the local knowledge was right.

However, on Wednesday morning, Lord Mayor Campbell Newman said on TV that they had revised the maps overnight, and people should check again if their homes or businesses could be affected. And yes, when I checked, the flood line had been moved just enough to indicate that my office/shop area were in danger.

I was not much encouraged when, getting to the office at about 8.15 am, the artificial lake within about 30 metres of my shops (and which had not been there in 1974) had already flooded across the road as far as the eye could see, and this was still 12 – 18 hours before the predicted peak. One house on the far side of the lake already looked to have a couple of meters of water over its ground floor.

It seemed prudent to remove the computers and take them home. This didn’t take too long, but then nearby residents mentioned that the road between me and my home, which I already knew was cut in one direction I could take, was now getting inundated (via the backflowing stormwater drains) in the other direction. If I waited too long I might not be able to get home at all.

I therefore left in a hurry with a lot of things left on the office floor. In any event I had to go pick up my mother from her retirement village, which I had been told was going to be evacuated as a precaution as well.

As I drove away from the office, there was quite a lot of activity in some lakeside houses to get furniture onto vehicles. Further along, I could see water over the road at the top of a side street which I knew led down closer to the lake. Many expensive houses down there would clearly already be inundated, and it was only about 9 am.

The main road just a little further along did indeed have a foot or so of water over it, but only for a short distance. I went and collected my mother, noticing the water was already down the far end of her street.

I got her home, which was already hosting another family (friends of ours with children) who had left their home in another flood prone suburb across the river and stayed with us on Tuesday night.

At about 11.30am, I drove back to see if I could get to the office, but the road was now covered with about 2 – 3 feet of water and the police were there, really only wanting to let residents through. It was not worth the risk.

So by midday I was back home, watching TV and wondering why coverage seemed very centred on inner city suburbs (such as Milton and Rosalie) and then leapt over to Ipswich and Goodna. I did feel slightly indignant that my already well flooded suburban area was not rating much of a mention.

Around 2 pm the power went off and stayed off for about 24 hours. I had telephone calls from friends near the office who said water had started coming up out of the stormwater drains in front of the carpark.

As Australian readers would know, the flood peak overnight on Wednesday was about 1 to 1.5 m less than they had predicated. In fact, I think by Wednesday afternoon, they knew that the river at Ipswich had peaked well under the forecast, so I did relax a little. Still, I was very glad to be able to get to the office on Thursday morning to see that, as in 1974, the flood water stopped in the car park driveway. If the peak had been as forecast, it would have been a very close call as to whether water would have entered the building.

The number of houses around my area which were flooded has surprised me, particularly around the lake, and in another area around a golf course. I’m not sure when they started selling lakeside land, and it may well have been before the Council restricted building homes on levels below the 1974 flood. But certainly, this would have been the first time since then that they faced a major flood, and I expect that many were surprised that the lake was capable of such a rise. There are certain other streets in the suburbs near mine which I am sure would only contain houses built since 1980, yet have dozens of houses flooded. I am sure there will be some questioning of the Council flood level advisory maps after this.

On Thursday afternoon, when the water had already dropped by a meter or so, I was able to get around a bit and take some photos. The quality may not be great, but clicking might make them a bit bigger:

One of the main local roads; houses down the street on both sides had plenty of water through them.

Street 2 resized

The road along my Mum’s retirement village. I was told houses down the far end had at least a meter of water through them. (You can also see the "high water"mud mark nearly half way up on the row of bushes on the left.) The retirement village was spared, again with water just reaching the car park entrance.

View towards boat ramp resized

On the left, well under the water, is the entrance to a boat ramp, playground and picnic area, none of which (including the roof of the toilet block, on the higher part of picnic area) could be seen. I think that’s the rear wheels of a car floating upside down near one of the light poles.

Next, my inner anti-sporting grump was not too shocked to see the Little Athletics club house and grounds, which I have been a reluctant attendee with my daughter on Friday nights last term, has had a make over:

Now for the best big flood scenes near me:

Shopping centre & highway sharpen

Highway in foreground, with shops in the distance. Closer detail to be seen in the next photo (remember, the water had already dropped by this stage):

Shops flood

And for last, the difference a day makes in a flood. Here’s a photo from roughly the same position late this afternoon:

I know the flood effects for me was nothing compared to all those who did have homes and businesses under water, and who may remain without power for days yet. Still, one brush with a flood this size is enough to satisfy any curiosity about what it’s like to be near a natural disaster.
