Glass apartments

Something you would have noticed if you watched the ABC report on Tianjin linked in my last post (not seen it? - well go back and do so now) was how many apartment tower blocks in the area lost every window in the blast.

I have been noticing in my wanderings around Brisbane lately that quite a lot of the new high rise apartments are being build with full length glass walls to the street, at least in some of the rooms.   Blinds provide privacy as needed.

I don't care for this trend.  Apart from glass being problematic from a heat regulation point of view (well, sometimes it works well if you want to warm a room in winter, but let's face it, for most of the year in Brisbane you are trying to keep a room cool), it just makes for what looks to me like a structurally insubstantial building.    I like bricks and concrete to provide shelter to me from the outside elements, and don't other people feel this way too?   (As well as not particularly wanting to feel like their block look like one of those kid's ant farms from the outside?) 

And, of course, you never really know when your building might be subject to a destructive air blast of human or celestial cause, and having your entire bedroom or living room wall blown over you is not an optimal outcome.

No, give me apartments with some external solid concrete walls, any day.

The ABC earning its keep, again

After Tianjin explosions, angry families return to toxic wasteland - 19/08/2015

The single best report I've seen on the Tianjin disaster was on the ABC last night by its resident foreign correspondent Stephen McDonell.

Excellent work which you just don't see from commercial networks.

Dirty work

I would assume that someone, somewhere, is presently doing a word search through this enormous file for Australian parliamentarians' names.

As discussed on Saudi social media...

Well, they don't have cinemas or pubs, and while spectacularly stupid things happening on their roads provides some entertainment, mostly it seems the Saudis amuse themselves by discussing the big topics on social media:
Manama: Saudi social media users have poured scorn on a fatwa that allowed young men married to ugly women to take drugs before intimate relations in order to have the delusion they are as beautiful as houris.
The fatwa said that hallucinogenic drugs can be taken for 30 minutes during sexual intercourse and only by men who are less than 40 years old. The drugs can be used only in the evening, it added.
“This is the ideal men who are unfortunately married with ugly-looking wives so that they can see them, under the effects of the drugs, as beautiful women, like Houris or lovely nymphs,” the fatwa said.
Houri is a Quranic term referring to “to be beautifully dark-eyed” women in heaven.
The origin of the religious edict is not known, although some users attributed it to a Moroccan figure, but it went viral on the Internet and sparked a huge debate in which most people expressed shock and sarcasm

Sounds nutty, but you should read more

Apollo Astronaut Says UFOs Came to Prevent Nuclear War

Edgar Mitchell, who has long believed in ESP and the paranormal, is turning up sounding like a nutter for talking about UFOs and nuclear war.

But - before you dismiss him entirely, you should read the surprisingly good Wikipedia entry explaining the very real controversy and concern in the late 1940's that mysterious green fireballs were indeed spying on the American nuclear program.

While I had read a short account of this before in some UFO book or other, the Wiki explanation makes it pretty clear that many people had seen them, including the scientists and technicians in New Mexico, and many genuinely thought they were so odd that were not a mere natural phenomena.

It does appear to be one of the greatest UFO style mysteries still around. 

Update:   Ooh.  This report, which I don't think I read at the time, contains a suggestion from a physicist in Brisbane that sometimes meteors might cause a ball lightning effect close to the ground.   I have a feeling that there was at least one case of what looked like ground following ball lighting in New Mexico at the time of the green fireball panic, so that idea does sound half plausible:
"A transient electrical link between the ionosphere and ground, created by meteors or some other means, could help to solve the mystery of many UFO sightings," Hughes told LiveScience. "Since such balls would be very insubstantial they would be able to move and change direction very fast as has often been observed."
Hughes detailed his findings online Nov. 30 in the Proceedings of the Royal Society A.

El Nino and La Nina from an Australian viewpoint discussed

2015-16 is shaping up to deliver a rollercoaster from strong El Nino to La Nina

A good explanation here of how these things usually pan out.  (Short answer - not good for Australia.)

Abbott, Heydon and the self inflicted wounds

I dunno, maybe I'm just reflecting my own judgement about this appalling government, but with all the TURC controversy going on, I strongly suspect that the public view of the Royal Commission has turned in a serious political negative for Abbott.   I think the Labor movement has succeeded in its PR to cast it as a political witch hunt, and that voters are thinking it is a sign of a government that is politically self indulgent and has no idea about getting on with more important priorities.   That the Abbott commissioned enquiries could backfire as political revenge over-reach was always on the cards, and I think it has indeed worked out that way.

And why does Tony Abbott even answer questions about bias of the Commissioner by praising him?  By doing so, he makes it sound all the more to the public that he has (or wants) the Commissioner in his pocket.  Surely the wise politician (yes, I know, we're talking Abbott) would take more a line of expressing confidence in the Commissioner making appropriate decisions regarding the conduct of the Commission, and leave it at that.  But Abbott goes further - much further - and hence worsens the self inflicted wound.

Much the same can be said about the Abbott approach to same sex marriage.   It seems that people really like the idea of a plebiscite (about 80% in favour in this morning's Newspoll of Canning), and that doesn't surprise me.  But Abbott wanting to not hold it until 2 or 3 years time? - as with the Royal Commission, this will all too obviously come across as mere playing politics.   Isn't that clear to Abbott's political advisers, especially when an election in 12 month's time is the obvious opportunity when the plebiscite could be conducted, at minimal cost?

PS:  having viewed a bit of Heydon's conduct of the commission yesterday, I think his skill and talent for this type of work may well have been (actually no, has been)  over-estimated.   Telling the ACTU barrister that he had an hour to decide whether to apply to disqualify himself?   It was a tactic that could only make Heydon look more biased.   He backed down, but it was a bad look that could only hurt himself.  Again, wasn't that kind of obvious?    He may have been great in other forms of jurisprudence, but I see no clear sign that he has a talent for this line of legal work.

Judith does a Steyn

I assume that Judith Sloan assumes she will never have another government or government authority job in which she professionally has to interact with any economist in the Productivity Commission, or indeed any economist who has ever so much as hinted at believing that climate change is real, and hence she can spend her early semi retirement in slagging off others to her heart's content, especially at Catallaxy.

In her latest outburst of note, I see she has followed the Mark Steyn route, using the "f" word:
As the Cats realise, the long march through the institutions continues.  But when it comes to the Climate Change Authority, no marching was required – it was set up with all the required poseurs and frauds in place from the getgo....
But how could chair of the CCA, Bernie Fraser, think it appropriate to give a running commentary on government policy, opposition policy and the wild estimates the CCA puts on these policies?

This is serious weird – nay outrageous – stuff and Bernie knows it (given his history in the bureaucracy).  But I guess he is on a mission, in part to help his mates in the industry super funds which are still overweight renewables.

The CCA comprises Bernie Fraser, Ian Chubb, David Karoly, Clive Hamilton and John Quiggin.

I wonder if Judith could expand upon which of them are the "frauds".   I note the use of the plural.

I also wonder why economists and academics on the receiving end of her condescending, and now (in my view) clearly defamatory vitriol never call her out for it. 

And not for the first time, I wonder why Sinclair Davidson never seems very worried about his potential legal liability for what the blog under his control says?   Maybe he can claim ignorance of some thread content, but he certainly can't do that very credibility for what one of his "star" contributors writes.

The Economist goes multiverse

Carbon capture was always a pipe dream

Over at ATTP, someone in a recent thread posted this 2011 video of Vaclav Smil explaining why carbon capture just never looked credible.  It's great, and it's a sign of the dissembling that has gone on in climate change policy (even amongst the well intentioned) that it was given credence for so long:

 

Varieties of weirdness viewers

Beachcombing's Bizarre History Blog is a continual delight, and I was amused by this paragraph in a recent post which was, initially, about the number of people who have hallucinations:
Beach has had some experience with collecting fairy reports: that is children, men and women who believe they have seen an entity that they would describe as a fairy, here is a little (ahem) ‘wisdom’. Those who see fairies split neatly into two groups: there are the shamanic mystics and the Joe Publics. Mystics are individuals who have recurrent visionary events throughout their lives: the lady who is presently cleaning the Beach family kitchen has spotted fairies in the garden; she has encountered ghosts and she has ‘feelings’ and ‘instincts’ that she chooses to act upon. In short, she would have been burnt alive in the sixteenth century, whereas today she is pleasantly eccentric company and a bad influence on the kids. Joe Publics, on the other hand, are those who have never had these experiences prior to a one off bizarre event. Some will absorb it, some will ignore it, some will eventually discount it. Back in the sixteenth century they were doing the burning, and if they did see aliens with tin-foil helmets descending from the sky they shut the hell up or blamed their neighbours.

The second category is more interesting than the first, because their experiences demand more of an explanation.

More photos noted

The Atlantic has an extraordinarily good set of weekly photos up at this link.  (Hope it's a permanent one.)

It includes this one, from China, the viewing of which alone makes me nervous:




On squeezing a teat

At this year's RNA Show, I forced the initially reluctant family into watching the very kid-centric milking and dairy display, but it was worth it all because we (wife, daughter and me - my son was too teenage to try) got to squeeze a cow's teat.  Never done that before.

I asked the high school student (from Nambour State High, where they keep cows) who was supervising my handiwork closely "how many litres can you get from one milking", and after some consultation, I was given the answer - 25 litres (!).

I said that seemed an awful lot, but I was assured that a cow's milk producing parts extend way, way up inside her.  I was given the impression that the tank, so to speak, extends well beyond the udder.

But, while not wanting to question the standards of Kevin Rudd's alma mater, I think the student was a bit misleading.

As far as I can tell, from this detailed slide show from the University of Wisconsin, where they seem to know a thing or two about cows, there are bits that help suspend the weighty udder that extend way up the internals of a cow:


 but the parts that produce the milk are pretty much in the udder area:


In any event, on the question of how much milk you can get from a cow in a single milking, given that there are normally two milkings a day, and there are sites saying that an average cow can produce 35 to 50 litres a day, 25 litres at once seems certainly a possibility, if on the high side of the range.    It's remarkable to think that, at a generous household consumption of 2 litres a day, one cow could make enough to keep 25 families happy.

While looking into this, I discovered that the Israelis are actually world leaders in coaxing high yields out of cows:
The average cow in Israel produces 12,000 litres of milk a year, double what Australian dairy cows produce, at 5,500 litres a year (Dairy Australia 2014).
It could provide useful lessons for Australia, with our similar climate.
"The Israeli dairy industry is cutting edge technology for dairying," said Dr Ephraim Maltz, of the Institute of Agricultural Engineering at Israel's Volcani Centre.
Israel has pushed the boundaries of what dairy cows can do.
Now, 12,000 litres a year is about 33 litres a day, if you count every single day of the year.  But as I think they are "rested" before being pregnant again, this isn't inconsistent with a higher yield when they are milked.   One animal's rights site says cows on average are milked 10 months of the year, so in Israel, that would indicate an average of 40 lives per milking day.   Why is the Australian figure in the ABC report above much lower than that?  Do they have more rest periods per year?

As just mentioned, the amount of milk cows are now enticed to produce is the subject of criticism from animal's rights groups.  It is a pity that unwanted calves are killed at a very young age - something I have noted here before.  In fact, it seems we don't even eat the meat ourselves:
Most will be destined for the slaughterhouse within days of birth. Bobby calf meat is considered to be of low value and is predominantly exported as ground beef and offal to Japan and the US.
Hence there is an ethical reason for the search to make a genetically engineered, yeast based, milk equivalent. Good thing I handled a teat while there was still time... 

Supersymmetry and the scale problem

To Avoid the Multiverse, Physicists Propose a Symmetry of Scales | Quanta Magazine

For some reason, this year old article turned up on my Zite feed, but I've decided it's blogworthy.

It's not a super easy article about supersymmetry (ha!), but it deals with an alternative idea that's being explored.

I see that multiverse cynic Peter Woit was quoting Joe Lykken (one of the physicists mentioned in the article) back in 2013 at Not Even Wrong with approval, so perhaps I should pay more attention...

Judging what works in education

Another NPR story, this time about a researcher in education from Melbourne, yet I am not familiar with him.   As with all of education research, it may be that some of his claims are debatable, but I strongly suspect this one is right:
Many education reformers tout school choice as a tool for parent empowerment and school improvement through competitive pressure. But Hattie says his research shows that once you account for the economic background of students, private schools offer no significant advantages on average. As for charter schools? "The effect of charter schools, for example, across three meta-analyses based on 246 studies is a minuscule .07," he writes.
On the other hand, I don't quite understand how you study this at all:
Putting televisions in the classroom, on the other hand, has an average negative impact of -0.18. Holding students back a grade really does hold students back, with an effect of -0.16.
How do you judge how the child would have done if they had not been "held back"?  

Update:  I also note that Naplan results in Australia indicate that having a mother born overseas is a good way to stay above the average. Bit hard to address that in your education system, though....

A credible argument about Art?

People Love Art Museums — But Has The Art Itself Become Irrelevant? : NPR

As this guy argues about the success of "art museums":

They offer a titillating experience. Lively interaction with the people
around you, well-dressed people — it's exciting. But what has happened
is the art museum used to offer objects, works of art, the finest that
we have. And it's gone from offering objects to offering an experience.
...

There's the critical moment: 1978. I was in college at the time. It
was the King Tut exhibit at the Met: 1.8 million people lined up to see
that show. And that got the attention of the administrators — not just
of the Met but the trustees of every museum in the country.

This hadn't happened before. Museums tended to be doudy places run by
superannuated financiers who every year would write a personal check to
cover the deficit. They suddenly realized that, well, "I don't have to
cover the deficit if you can produce more of these blockbuster
exhibits."

I actually talk about this in the piece. It was almost 20 years to the day, 20 years after The Treasures of Tutankhamun, the Guggenheim did The Art of the Motorcycle.
And it was equally thrilling, equally successful, but it tells us that
our society can no longer distinguish — effectively distinguish —
between a Harley-Davidson Sportster and a 3,000-year-old golden mask
from Egyptian New Kingdom, can't make a qualitative judgment about
intrinsic value.

So, the museum seemed to be more and more successful, but there's been a little bit of a bait-and-switch that's going on behind the doors of many.
The argument is not inconsistent with what I wrote about modern art and my reaction to it in 2009.  (The post also remains the only time I have posted a photo of myself on the blog.)

Not exactly a true "space elevator", but may still be useful

Canadian firm patents inflatable space elevator

The dodgiest bit is the flywheel system for "dynamic stability".

I wonder if such a tower would be a good base from which to then grab onto an orbiting skyhook tether with which to get into orbit?   Maybe just need a short launch up, clear of the tower, to be snared by the hook...

Economists getting random

Can randomized trials eliminate global poverty? : Nature News & Comment

This is my bit of Soon-bait for the day.

Given my skepticism about the utility of economists' analysis of climate change, my first reaction is to be somewhat skeptical of some of the work of the "radomistas" too.

Why does the US presidential gene pool seem so shallow?

There seems something distinctly "off" about the US political system when it keeps throwing up Presidential candidates that seem so underwhelming to the rest of the world.   I don't really remember when I last felt  particularly impressed by the qualities of a candidate.   I didn't even think Obama was impressive; he certainly seemed under-qualified, and his promise of "hope and change" was very much like the shallow sloganeering of the Kevin Rudd ascendency.  (Although, as it happens, I think Obama has turned out to be a pretty good President, after all.   His recent interview with David Attenborough showed an intelligent and decent man, even if his image is assisted by the comparison with the dimwittery that has enveloped his opposition.  His legacy in terms of health care reform, getting serious about some action on climate change, and on dealing with difficult economic circumstance, will stand him well in future, I think.)

Dismissing the Trump clown show, as far as I can tell Jeb Bush still seems the most likely Republican candidate.   As many have noted, it's funny how Americans rebelled against dynastic rule a couple of hundreds years ago only to more or less endorse another form of it now. 

Of course, everyone knows I follow the Krugman line that the Republicans have gone mad, and is currently a lost party that needs some very dramatic changes before it becomes  credible again.   But even on the Democrat side - I have never followed the Clinton family story closely, but remember how vigorously Hitchens condemned them, and I worry when any politician seems prone to self-aggrandising flights of exaggeration such as Hilary has displayed in the past.   (Shades of Reagan telling movie anecdotes, apparently believing they were true, if you ask me.   And no, I never thought highly of Reagan, even before it was known he was well on his way to dementia while still President.)

As for the only other Democrat candidate I have heard mentioned - Joe Biden??   Really?  He may be a decent enough fellow, but I had the impression he was mainly notable for making silly gaffes and had a distinct "Dan Quayle" feel about his vice presidency.

The amount of money that anyone needs to run for President in that country seems truly ridiculous, but I still don't really understand why that results in candidate runs by people who fail to impress.    Or is it just me, feeling underwhelmed ever since the last Kennedy was shot?   I do feel a bit hypocritical, because with John Howard, I sort of liked the way he was underwhelming in physical presence and in oration, but thought he displayed relatively sound judgement and decency and that this is what matters at the end of the day.  Perhaps it is because of the charisma of the Kennedy family that I feel the US leader should be impressive not just in deed but in appearance and campaign rhetoric too. 

The more important story

While the political sideshow of an incompetent and rudderless government sucks up most coverage (as well as media sympathies on gay marriage as the greatest injustice the nation has ever seen, apparently), the truly important story of the government's actual punishment of those people detained in Nauru and Manus in order to stop others leaving Indonesia gets short shrift.

This should have been the lead story in the media this morning, and on  7.30 last night.

Still, they did a decent job, the ABC, and it's pretty disgraceful that there is not more attention paid to this issue.  (It doesn't even appear on The Australian's front web page, as far as I can see.  Fairfax and The Guardian feature it fairly prominently.)
