The problem that some physicists warned about - what if the Large Hadron Collider finds Higgs, but nothing else very interesting - seems in danger of becoming a reality; and given that there's a more widespread acknowledgement than ever that string theory is an untestable waste of time (well, this is my impression, anyway), it seems that the physics community has fallen into a bit of a depression recently.
Here are a few pieces to back this up:
a. John Horgan wrote a great piece this month "How Physics Lost its Fizz", and his explanation of why he (used to) find physics so fascinating mirrors a lot of my own interests. But whether it deserves this full amount of pessimism still seems a bit unclear to me - the problem being that you never know what is just around the corner in both theory and experiment, although it certainly seems true that the era of building ever larger particle colliders is over.
b. Starts with a Bang notes that early inflation of the universe sets a natural limit on how far back you can see, as explained in the post "Physicists Must Accept That Some Things are Unknowable". Not a new idea, perhaps, but good to be reminded. (And by the way - I really don't quite understand the way inflation is so widely accepted when, at the same time, as far as I know, there is no clear understanding of what caused it. It has always seemed to me to have more than a touch of the Deus ex machina about it.)
c. You can also watch a Downfall parody video with a difference: Hitler doesn't get a postdoc in High Energy Theory. Somewhat amusing, and realistic, apparently.

Against against the stimulus
Idiotic Anti-Stimulus Talking Point Won’t Die -- NYMag
Heh. Jonathan Chait writes of the chart that I am sure I have seen at Catallaxy (I think posted by S Davidson himself?):

As I noted before, we can’t prove that the stimulus reduced unemployment because we can’t
measure exactly what unemployment would have looked like otherwise. But the talking point that the stimulus failed because unemployment exceeded the forecasted level is not a serious argument. No reasonably informed person could take it seriously. And yet this blunt and easily refuted bit of propaganda continues to circulate seven years later within the airless bubble of the conservative echo chamber.

Why so many awards?
I'm honestly interested in the question "how many Australians understand our awards system in any detail?", because unless I'm doing some unfair extrapolation from my own ignorance, I would say that there are very, very few. (And most of those being "establishment" types who have been around a while and keep an eye on which of their colleagues have got a gong when they haven't yet. In fact, it may only be those Australians who have a clue about the difference between an AO, AM and an OAM.)
And looking at the list of award recipients this year: aren't we starting to run out of people worth congratulating when there are so many each year? Patsy Biscoe may have done a lot for the community of the Barossa, and I know nothing of the charitable efforts of Liza Wilkinson, but this type of work is its own reward, surely?
And, of course, how can I overlook the award given to "Groucho" Henry Ergas? Here's what he wrote in a piece kept at the IPA website since 2009:
To be fair to Ergas, even though he doesn't deserve it because those lines are such a poor explanation of what he is trying to say, his article is actually arguing more that statistics and "evidence" is malleable, depending on the end result desired. In the article, he later clarifies his position to:
And, strangely, the citation in the SMH says he is getting his OA partly for distinguished service to "higher education". Yet in 2014 he wrote a column in The Australian that complained:

The myth is that evidence-based policy is good policy: nothing could be further from the truth. The value of public policy does not depend on whether it rests on evidence, but on whether it seeks goals that are worth pursuing.Well, talk about your succinct summary of all that gone wrong in Right wing politics and policy over the last decade or so, particularly in the US!

In the article, he later clarifies his position to:
Evidence is perhaps a necessary condition for sound policy, but it is far from being sufficient."Perhaps"! How generous of him to allow evidence to reach the heights of "perhaps" being important to policy.
And, strangely, the citation in the SMH says he is getting his OA partly for distinguished service to "higher education". Yet in 2014 he wrote a column in The Australian that complained:
That is not to deride our institutions of higher learning. But a stroll down the corridors of even highly rated universities would shock the most hardened of troopers. Entire buildings seem to have been struck by specially developed neutron bombs: the structures are intact, but the academics are nowhere to be seen.This prompted actual teaching academic Harry Clarke to write:
What teachers there are tend to be tutors, all too often foreign postgraduates struggling with the mysteries of the English language, and part-timers on short-term contracts.
No doubt many academics take their vocation seriously, but they are swamped by those too intellectually feeble to get employment elsewhere, too satisfied ever to leave and too young to retire.
Your views on inactivity in the universities are just wrong and outdated. Education and teaching are central priorities and have been for several decades. But that is just my claim just as your views are a claim. You provide no evidence to justify your impressions. Why do Australian universities do so well in international rankings if they are so poor? Why do we attract so many international students? Is this export success story based on wrong information? Your judgement about academics being intellectually feeble likewise reflects pure prejudice partly because many of them don’t take you very seriously. Most academics regard your politics (and your propensity to dominate verbal exchanges with long rambling monologues) with well-deserved disgust. You are wrong about professors regarding teaching undergraduates as only a burden. It is simply untrue – good researchers are invariably good teachers since the two things go together.Now, I don't know much about Ergas' contribution to infrastructure economics, and (to my surprise) economics journalist Peter Martin seems to think Ergas is a worthy recipient, but I'm pretty convinced that his getting this award makes for a great case that the country is giving out too many.

And you thought the Freemasons were bad
Australian politics is pretty boring at the moment: Malcolm Turnbull would easily win the election if only he could continue doing nothing before it has to be called. Just like the Queensland Premiership, where Annastacia Palaszczuk maintains popularity by simply keeping a pretty low profile, the non-scary leaders who get to follow those who do scare the public have a pretty easy run for quite a while.
Of course, there is the bizarre spectacle of Kevin Rudd thinking he would be good for the United Nations - but surely that is more of a matter of entertainment than a serious possibility. Why would Julie Bishop say the government would even consider it, though? (Kevin doesn't look all that well to me in recent photos I've noticed, too, although they might be old file ones I suppose.)
So without politics to worry about at the moment, I wandered over to Arts & Letters Daily, to read a scathing review of book about Augustine. It's lengthy, but this episode is noteworthy for its insight into ancient rumour mill:

So without politics to worry about at the moment, I wandered over to Arts & Letters Daily, to read a scathing review of book about Augustine. It's lengthy, but this episode is noteworthy for its insight into ancient rumour mill:
The story begins when Augustine, as a Manichee, may have heard (must have heard according Lane Fox) an anti-Manichaean slander that the cult’s Elect, at their secret meals, had sex on top of flour spread on the floor. Their joint juices were spilled on the flour, and the male like some unknown Onan spilled his seed upon the ground, making the flour a carrier of the particles of light from the Elect, as the members of the Manichee sect were called. Bread was then made of the flour for the Elect to consume. Like most attacks of bigotry, this slur was illogical. What good would it do for the Elect to recycle light out into bread and then back into the source of the light in the first place? There is no way to know how widely this crude attack was known to people, much less to know how many credited its nonsense.Erk.

Down the black hole to a new universe
An abstract on arXiv:
We investigate the effect of a black hole as a nucleation cite of a false vacuum bubble based on the Euclidean actions of relevant configurations. As a result we find a wormhole-like configuration may be spontaneously nucleated once the black hole mass falls below a critical value of order of the Hubble parameter corresponding to the false vacuum energy density. As the space beyond the wormhole throat can expand exponentially, this may be interpreted as creation of another inflationary universe in the final stage of the black hole evaporation.I'm pretty sure I saw another paper making the same argument on arXiv last month, but I forgot to note it. (I think Sabine H saw it too.) Should try to find it...

Maybe this will help...
OK, if you don't understand, listen to this.
(It appears Nesmith has required all YouTube's of Elephant Parts to be taken down from YouTube, which is fair enough I guess.)
How good a debater is Cruz? (A short, funny Colbert piece)
Surely even Republicans would find this funny:
And while you are on the Colbert channel, you may as well look at this clip just to see how extraordinarily similar Colin Hanks talks, looks, and acts like his father Tom. As many people say in comments after, it's almost spooky.

Ross Douthat confesses
My Sarah Palin Romance - The New York Times
It was, however, a very brief romance.
And look, if one looks back at this very blog (no, I'm not going to help you find it), one will see that I too thought that her very first appearance on the national stage showed an impressive and natural confidence that might work well. But then, as Douthat says, she had to talk national policy to the media, and it all fell apart.
So I actually have a bit of sympathy here for Ross. But I still don't think he knows the way forward for the Republicans. No one on the Right has a proper grip on what has happened to the American Right, if you ask me.

Don't worry, Catallaxy, we already know you don't "do" science
That’s a silly number | Catallaxy Files
Being ideologically dedicated to as tiny a government as possible because - well, just because! - the economists of Catallaxy don't like the idea of government funding science. Which is consistent with the blog being deeply devoted to climate change denial.
The blog would be better served by just not discussing science at all. Crank economics is enough of a burden, let alone taking on crank science.

Trend change discussed
Changes | Open Mind
Tamino notes that, for most climate change indicators, it's not yet clear whether the trend rates are changing (that is, accelerating.) But, of course, the actual current trends are worrying enough.

Furry empathy, re-visited
Consoling Voles Hint at Animal Empathy - The Atlantic
I like research into niceness, but I see that people were doubting that rats saving other rats were displaying empathy. But perhaps this study into prairie voles makes a stronger case. (I'm still generous in my interpretation of the rat study, too.)

They have their standards
Once again (and there are a million other examples), I am bemused by the Catallaxy outrage at how leftists "hate" (someone said something mean about the late Bob Carter, and Sinclair Davidson thinks its worth noting), while over at another thread a "leftist" ABC journalist is called (for no apparent reason relevant that I can see) a "$20 a trick hooker", and no one else in the thread bats an eyelid.
(Incidentally, that Riccardo Bosi is one of the nuttiest of any commenter on the Australian blogosphere. Here's his follow up to the "hookers" comment:

There’s a very good reason why I went public with my name, and I’m just getting warmed up. The hookers at the ABC are just one group who will eventually be taking a long walk off a short pier.He's ex-Army, rabidly Christian and anti-abortion, hates Islam with a passion, and has said he's going to be undertaking some speaking tour of Australia to convince everyone of God knows what.)
