A high suicide rate

Axios reports:

The suicide rate for Americans aged 15 to 24 years old — the older half of Generation Z — is the highest it's been since at least 1999, according to Centers for Disease Control data.
I was curious how this compared to Australian recent suicide rates for youth.   Turns out the American rate is very high, by the looks:

Against the Boris

Oh look:  a very anti-Boris Johnson opinion piece in, of all places, National Review:
As I explained a few weeks ago, the Conservative party is facing possible extinction; their complete failure to implement Brexit has lost them the majority of their voters. Many of Johnson’s supporters in Parliament are deeply skeptical of his character, but they are voting for him because they see him as the only way out of their crisis. This is the point made by Madeleine: Boris Johnson is not Jeremy Corbyn — if the Tories are to face a general election, they want a chance of surviving it.

But are they wrong to see him as a winner? In the long term, absolutely. Johnson is no longer the same man who twice won the London mayoral election. In those days, he was seen as a pro-immigration liberal conservative — the Tory for people who don’t vote Tory. Now, rightly or wrongly, he has become associated with a hostile brand of divisiveness — and it is Rory Stewart, as it happens, who has adopted the “outsider Tory” mantle. Johnson’s showman popularity among right-wing voters might be enough to win him the next election, but the average age of a Conservative voter has been increasing consistently for decades. People are forgetting that this is a party that has had one outright majority in 25 years. If it wants to survive, it needs to attract voters from the center ground.

For the party, then, there are no good outcomes. Either they opt for a candidate who will delay Brexit, thereby postponing an election but further weakening their immediate position, or they opt for an unpredictable renegade who, if tamed, might help them keep their parliamentary seats. I am writing this while listening to a fascinating discussion of the issue on the Talking Politics podcast (highly recommended to anyone with the slightest interest in British affairs). Here, the ever-insightful David Runciman asks his Cambridge colleagues the following: Is the fact that the Tory party is even contemplating making Boris Johnson its prime minister such an unusual thing that it’s a symptom of a party that’s already dying?

It’s an interesting question, and it pays a moment’s thought. Ask almost anybody who has worked closely with Johnson, and they speak of a Class A impostor — in the words of former Telegraph editor Max Hastings, a “gold medal egomaniac.” Any scarce praise usually refers to his ability to delegate — deference may suit a mayorship, but it will not suffice as prime minister. A deeply questionable personal life aside, Johnson’s career has been a collection of mishaps — one of which, during his time as foreign secretary, helped send a British citizen to prison. He is charming because of his Bertie Wooster-esque meandering mode of speech, but baseless bluster is not a characteristic that bodes well for a future as prime minister. He has never been a good performer in the House of Commons or in media interviews, and one daren’t imagine how his waffle will fare in Prime Minister’s Questions.
Jason, this is very consistent with my view of Johnson as stated in my recent comment in response to you, and I hadn't even found it at that time.   

Weird deal positions

As Slate notes, re the Trump administration and Iran:
The move comes as Iran has threatened to disregard uranium restrictions outlined in the 2015 nuclear deal that aimed at curbing Tehran’s nuclear ambitions in return for sanctions relief. After years of deriding the nuclear deal as “the worst deal in history,” President DonaldTrump withdrew the U.S. from what’s formally known as the Joint Comprehensive Plan of Action and reinstated sanctions on Iran. The Trump administration, already suffering from a serious credibility deficit with allies, is now in the awkward position of demanding that Tehran comply with an agreement the American president has not only derided but pulled out of! “Administration officials found themselves Monday grappling with whether to press the remaining parties to the deal, including Britain, France and Germany, to demand that Iran stay in compliance,” the Associated Press reports. “They must also consider if such a stance would essentially concede that the restrictions imposed during the Obama administration, while short of ideal, are better than none.”

Tariffs and long term pain

A pretty convincing sounding explanation at The Atlantic about how China is responding to Trump's tariff war in ways that may well result in long term harm to parts of the American economy. 

Ethics from the BBC

Not a bad essay at the BBC:

Hot stuff for renewable energy storage

One energy storage idea is just to heat stuff up when you have enough spare power, and use the hot stuff to make steam for a turbine when the renewables are off line.

While we would have all heard of that as being an advantage of solar thermal plants which use molten salts, there are simpler materials that can be used for heat storage.  Surprisingly, Siemens has just opened one in Germany that uses volcanic rock:
Spanish renewable energy giant and offshore wind energy leader Siemens Gamesa Renewable Energy last week inaugurated operations of its electrothermal energy storage system which can store up to 130 megawatt-hours of electricity for a week in volcanic rock....
The newly-opened electric thermal energy storage system is billed by Siemens Gamesa as “The Future Energy Solution” and as costing “significantly” less than classic energy storage solutions. Specifically, according to the company, even at the gigawatt-hour (GWh) pilot scale, ETES “would be highly competitive compared to other available storage technologies.”
The heat storage facility consists of around 1,000 tonnes of volcanic rock which is used as the storage medium. The rock is fed with electrical energy which is then converted into hot air by means of a resistance heater and a blower that, in turn, heats the rock to 750°C/1382 °F. When demand requires the stored energy, ETES uses a steam turbine to re-electrify the stored energy and feeds it back into the grid.
In the comments to that article, someone points out that an Australian company has just started using hot molten silicon!:
1414 Degrees is pleased to report progress with the GAS-TESS implementation at the Glenelg Wastewater Treatment Plant.

The full suite of ten biogas burners are commissioned and performing above expectations. The silicon storage reached operating temperature and the turbine started generating electricity on Saturday 25th May. It is supplying hot water from the turbine exhaust to the treatment plant, augmenting the continuous hot water supply from the biogas burners exhaust. Electricity is being delivered to our load bank pending SA Water completing the approval processes to connect to the National Electricity Market.


An innovative energy storage system from South Australia?   I hope it works...

Something to be happy about


How's that for a Tuesday night dinner? 

Thanks to my wife and Costco...

A little bit "Macron Youth"?

Not entirely sure about this idea:
Nearly two decades after France phased out conscription for men, some 2,000 teenagers on Sunday began a pilot programme for a new national civic service, a pet project of French President Emmanuel Macron.

For a fortnight, the 15- and 16-year-olds will leave home for training in first aid and other basic skills, followed later by another two weeks of volunteering.

Macron caused surprise on the campaign trail in 2017 by promising to introduce a month-long compulsory national service, saying he wanted to give girls and boys "a direct experience of military life".

The proposal got a cool response from the army, which baulked at the prospect of having to put millions of teens through their paces, prompting the government to come back with proposals for a compulsory civic service instead.

Some 2,000 youngsters, including 50 disabled teens, were chosen out of 4,000 volunteers for the first part of the trial, which started Sunday at boarding schools, holiday villages and university campuses around the country.

The group includes high school students, drop-outs, apprentices and vocational school trainees.
Each volunteer will leave home for another region for the two weeks, during which time they will be required to wear navy uniforms and sing the "Marseillaise", France's national anthem, every morning.

Described as an "integration phase", teens will be taught first aid, map reading, emergency response for different scenarios and other skills.
It'll probably end up in some form of under-age sex scandal, and that will be the end of it.   The uniform is a bit, um, naff? too:



Things to be unhappy about

*  Economic malaise in Australia:   I'm sure some people voted for the Coalition out of concern that reforms by Labor would drive down confidence in at least the real estate market.   It seems pretty clear, however, that the Coalition win had hardly brought signs of improved confidence to any market.  I bet retail is still flat as a tack, and what worse nightmare could any Sydney real estate who specialises in high rise apartments endure than the dramatic cracking appearing in two buildings in under 6 months?    (In fact, it will be interesting to see how that affects all "off the plan" sales in every capital city.   I wonder if it even has an effect on the country's reputation for tertiary education - it's not exactly the best advertisement for engineering expertise.)  

I'm not entirely sure anyone really has a good grip on why there is, more or less, an air of impending doom on our economy.  Greg Jericho does a lot of graphing, but it doesn't explain why things seem stuck on "not getting any better". 

Does everyone sense we are in some sort of transition, and to what, no one knows?   The economy can only bear so many new burger chains and craft beer outlets, I guess, and maybe people are sensing that we're reaching saturation level with them.

* "Summer" movies.   Well, it's far from the first holiday movie season for everyone to be complaining about the number of unwarranted sequels - but this one seems to be full of underwhelming entries.   I was thinking of seeing Men in Black International, but if a trailer can't come up with much in the way of funny bits in what is meant to be a comedy, I am inclined to believe the lukewarm reviews are right.   

*  The Trump administration:  who has confidence that it won't stumble into/deliberately provoke an unnecessary and dangerous war with Iran?   Who (with a brain) thinks the trade war tactics are good for America, let alone the globe?   How's that government deficit going?   It's a slow moving policy disaster.

* Boris Johnson as PM of Britain:   the English equivalent of Trump in many ways, showing how terrible Right wing politics has become around much of the world.   And they have a uniquely bad example of Left wing politics in that country too.   That country, if not the whole globe, seems to be suffering some kind of bad alignment of the stars at the moment.   When will it pass?


A quantum argument against uploading your mind

I have only skimmed through this paper on arXiv, and don't have any idea about its plausibility, but it's interesting at least.  Here's the abstract:
Killing Science Fiction: Why Conscious States Cannot Be Copied or Repeated

Several philosophical problems arising from the physics of consciousness, including identity, duplication, teleportation, simulation, self-location, and the Boltzmann Brain problem, hinge on one of the most deeply held but unnecessary convictions of physicalism: the assumption that brain states and their corresponding conscious states can in principle be copied. In this paper I will argue against this assumption by attempting to prove the Unique History Theorem, which states, essentially, that conscious correlations to underlying quantum mechanical measurement events must increase with time and that every conscious state uniquely determines its history from an earlier conscious state. By assuming only that consciousness arises from an underlying physical state, I will argue that the physical evolution from a first physical state giving rise to a conscious state to a second physical state giving rise to a later conscious state is unique. Among the consequences of this theorem are that: consciousness is not algorithmic and a conscious state cannot be uploaded to or simulated by a digital computer; a conscious state cannot be copied by duplicating a brain or any other physical state; and a conscious state cannot be repeated or created de novo. These conclusions shed light on the physical nature of consciousness by rendering moot a variety of seemingly paradoxical philosophy and science fiction problems.

How's that Indian heatwave going?

Some rains have arrived, but the death toll (such that is known - again I have extreme doubts about accurate numbers on this) has risen.   What's more, it was a pretty bad scene in some areas, apparently:
Tens of thousands of people in drought-affected villages in north India have left their homes because they do not have any drinking water either for themselves or for their cattle.

Even in the state of Jammu and Kashmir in the Himalayas, where many Indians go to escape the summer heat, the temperature has reached 39C.

The rush to the higher ground resulted in huge traffic jams at the weekend that snaked around the mountains. People had to sleep in their cars because towns such as Shimla and Nainital – known as hill stations from the days of the British Raj – had no spare hotel rooms.

“It was unbelievable. The hills were alive and heaving with cars and SUVs and a journey that should take one hour took five,” said Sumith Verma, a Nainital resident.

About two-thirds of the country has been affected by the blistering heat, which looks set to become the longest heatwave the country has ever experienced.
But hey, Rowan Dean's wearing a funny tie; rich retirees travel the world and see shrinking glaciers (one of the clearest markers of global climate change) and say "natural variation";  and Al Gore made some incorrect predictions.   [Just my routine go at the incredible non-seriousness of everyone associated with Catallaxy.]

Tighter regulation

Is there a bit of a pushback against the way legalisation of marijuana is happening in the US? 

An opinion piece in the NYT argues it should not be sold to those under 25 on health grounds - a suggestion likely to not go over well in colleges across the nation.

The Washington Post reports that the high potency of marijuana products sold in Colorado is causing problems, as well as where it can be sold:
The critics also insist that more must be done to maintain tight regulation of the industry. That’s not been the case so far, they argue, with dispensaries opening near high schools in Seattle and with retail and medical pot shops in Denver outnumbering Starbucks and McDonald’s locations combined. 
Americans are rather naive, it seems to me, when it comes to the matter of  how regulation affects society.

Some Krugman techno optimism tweets of note



Nuts in the country

Nothing's creepier than stories of rural nuts who would exploit backpackers, sexually or otherwise, as per some of the stories told in this ABC article.

Maybe it's just the results of the recent Federal election annoying me, these stories are certainly helping feed my current biases against anyone who lives more than (let's say) 150 km from a capital city.


A strange story of Hollywood inspiration

According to a book reviewed at Nature, the 1998 movie Enemy of the State inspired research to implement new, powerful surveillance technology:
it was ..an inspiration, even a blueprint, for one of the most powerful surveillance technologies ever created. So contends technology writer and researcher Arthur Holland Michel in his compelling book Eyes in the Sky. He notes that a researcher (unnamed) at the Lawrence Livermore National Laboratory in California who saw the movie at its debut decided to “explore — theoretically, at first — how emerging digital-imaging technology could be affixed to a satellite” to craft something like Big Daddy, despite the “nightmare scenario” it unleashes in the film. Holland Michel repeatedly notes this contradiction between military scientists’ good intentions and a technology based on a dystopian Hollywood plot.

He traces the development of that technology, called wide-area motion imagery (WAMI, pronounced ‘whammy’), by the US military from 2001. A camera on steroids, WAMI can capture images of large areas, in some cases an entire city. The technology got its big break after 2003, in the chaotic period following the US-led invasion of Iraq, where home-made bombs — improvised explosive devices (IEDs) — became the leading killer of US and coalition troops. Defence officials began to call for a Manhattan Project to spot and tackle the devices.

In 2006, the cinematically inspired research was picked up by DARPA, the Defense Advanced Research Projects Agency, which is tasked with US military innovation (D. Kaiser Nature 543, 176–177; 2017). DARPA funded the building of an aircraft-mounted camera with a capacity of almost two billion pixels. The Air Force had dubbed the project Gorgon Stare, after the monsters of penetrating gaze from classical Greek mythology, whose horrifying appearance turned observers to stone. (DARPA called its programme Argus, after another mythical creature: a giant with 100 eyes.)

Some books use blockbuster action films to demonstrate — or exaggerate — a technology’s terrifying potential. Here, Enemy of the State shows up repeatedly because it is integral to the development of Gorgon Stare. Researchers play clips from it in their briefings; they compare their technology to Big Daddy (although their camera is so far only on aircraft, not a satellite). At one point, incredibly, they consult the company responsible for the movie’s aerial filming. (It set me wondering — which government lab out there is currently building the Death Star from Stars Wars?)
