Bohm may be back

Pilot-Wave Theory Gains Experimental Support | Quanta Magazine

I hadn't heard of this recent support for Bohm's approach to quantum physics until this article - but Bee tweeted it, so it must be OK.

Yet more on Trump stupidity

The Know-Nothing Tide - The New York Times

This paragraph was interesting, in particular:

Speaking of Israel, Trump says, “President Obama has not been a friend
to Israel.” Right, he has not been a friend to the tune of over $20.5
billion in foreign military financing since 2009. He has not been a
friend by providing over $1.3 billion for the Iron Dome defense system
alone since 2011. He has not been a friend by, in 2014, opposing 18
resolutions in the United Nations General Assembly that were biased
against Israel; by helping to organize in 2015 the first U.N. General
Assembly session on anti-Semitism in the history of the body; and by
working tirelessly on a two-state peace, not least on the security
arrangements for Israel that are among its preconditions. He has not
been a friend by turning the other cheek in the face of what Nancy
Pelosi once called “the insult to the intelligence of the United States”
from Israel’s prime minister, Benjamin Netanyahu.

The parties' weakest members

An election campaign is generally pretty dull until you get to the policy speeches, and this one is certainly no exception.  But I thought I would list those characters who are obviously the most annoying from each party:

Liberals:   Peter Dutton wins hands down.  It's hard to imagine anyone liking him, no matter what side of politics, isn't it?  George Brandis perhaps comes in at a close second.  He seems to occasionally laugh at himself, however.  Dutton seems like a zombie.

Labor:  Stephen Conroy:  an annoying haircut, accent and general manner in a man who frequently lets his mouth run ahead of his brain.  Keep him off the airwaves as much as possible, Bill.

Nationals:  George Christensen.   An unpleasant, buffoony appearance in which the exterior matches the interior character.  Or so it seems.  Maybe he's a lovely man in private.  (Just kidding, it's too hard to imagine.)

Greens:  Adam Bandt:  just when the party gets a heterosexual, more or less reasonable sounding, leader, we still get reminded of the "preciousness" of a large part of the Greens whenever Bandt gets his head on TV. Sorry, I find him annoying. 

A genuine fool

Exclusive: Skeptical Trump says would renegotiate global climate deal | Reuters

The thing about him is that he is such an obvious fool, but he flip flops on most issues (save climate change, where he is continually wrong) that he well be malleable by advisers around him.  However, who could possibly trust his judgement about the quality of the advisers he would chose?

Not cheerful news

Scientists predict extensive ice loss from huge Antarctic glacier -- ScienceDaily

By studying the history of Totten's advances and retreats,
researchers have discovered that if climate change continues unabated,
the glacier could cross a critical threshold within the next century,
entering an irreversible period of very rapid retreat.


This would cause it to withdraw up to 300 kilometres inland in the
following centuries and release vast quantities of water, contributing
up to 2.9 metres to global sea-level rise.

 A full 300 km retreat may take "several hundred years", but still...

A dangerous precedent

Rodrigo Duterte’s Talk of Killing Criminals Raises Fears in Philippines - The New York Times

Reading about the trouble the Philippines has had with criminals and lawlessness in relatively recent history, it strikes me again as odd how some of the most overtly Catholic countries can have major trouble with gangs -  Italy's mafia, Mexico's drug gangs, and the Philippines with whatever their criminality has been about.

A very tricky issue

There's No Such Thing as Free Will - The Atlantic

This perhaps isn't the best article on the matter of free will, and the consequences of not believing in it, but still worth reading, I think.

As it happens, I noticed that the edition of Philosophy Now magazine  currently at my local newsagent had several articles on free will.  I haven't finished them all, yet, but I'll probably get around to mentioning one of them here, later.

[I keep thinking, incidentally, that the current way young folk in particular in Western society are thinking about gay and transgender issues is influenced not just by Freud, but by their increasing and almost unconscious acceptance that free will is not real, and our feelings are all determined by a dance of atoms that we have no control over.]  

An interesting result

Magic-mushroom drug lifts depression in first human trial : Nature News & Comment

As readers would know, I'm the last person to endorse recreation use of drugs (beyond alcohol), but persistent and deep depression is a very serious thing, and if one dose of a hallucinogen seems to be shown to help most people with the condition, it's worth considering.

The biggest buffoon to ever run for President

I had missed the "Trump complains about modern hairspray" story from last week, but here it is, covered by Colbert:



You would have to be seriously stupid to consider voting for this clown.

Oh look - Steve Kates is still making sympathetic posts about him.   (And a bunch of Right wing culture warriors still think he's great, 'cos he annoys "Leftists".)   I see that some anonymous contributor to the blog is also now re-posting items from a Fox News commentator about Hilary Clinton.   Seriously, the place has become so dire that you can feel it slowly sucking intelligence out of the universe. 

Probably a bad thing...

If California legalizes marijuana, consumption will likely increase. But is that a bad thing? - LA Times: The data from Colorado and Washington, where voters legalized recreational marijuana in 2012, are still preliminary. We do know, however, that the number of Coloradans who reported using marijuana in the past month increased from about 10.5% in 2011-12 to nearly 15% in 2013-14. In Washington, reported use increased from just above 10% to almost 13%.

Given that both states' preexisting medical systems already provided quasi-legal availability, it is hard to imagine that commercial legalization did not account for at least some of these increases. (That said, other factors could influence marijuana use and it will be some time before researchers have enough data to conduct rigorous analyses. Some of the increase could also come from respondents being more honest now that marijuana is legal in their states).

But is an increase in marijuana consumption a bad thing from a public health standpoint? Not necessarily.

I didn't realise the increases were that large, but this article is from a pro-legalisation advocate.

On the matter of public health, the problem is partly the length of time it takes to work this stuff out.  The rate of increase in smoking in the relatively young is the major issue, but its full effect may take years to clearly establish.

Given that the worst possible health effect (apart from possible car accident death) is a really debilitating mental illness (schizophrenia), surely you don't need too much of an increase in the rate of that to say that its increased use is a real public health negative.

Good grief

Donald Trump to meet with Henry Kissinger on foreign policy.

I see that Kissinger is 92 now.  Mind you, his safe "use by" age was probably 40.

Viewing recommendations

Greece With Simon Reeve | SBS On Demand

This documentary/travel show about Greece (last night on SBS) was very good, if somewhat depressing, viewing.   From the (pretty obvious) environmental degradation of the Mediterranean sea around Greece, to the surprisingly nutty men of Crete, it was fascinating in a way I didn't quite expect.

After that, although I missed part of it, there was Matthew Evans' show What's the Catch, about where our seafood comes from.  This is a repeat, evidently, but I had missed it the first time around. 

Again, this was very eye-opening.   The fishing practices around Thailand, to make the fish meal that is fed to their cheap farmed prawns that I already refuse to buy at the supermarket, were a real worry.  The problem is, places like Dominoes pizza will source their prawns from countries with such dire environmental practices.

Anyway, all praise SBS and ABC, again: for running educational material you won't see on commercial television.

Looking at why evangelicals would support Trump

Trump’s success with evangelical voters isn’t surprising. It was inevitable. - The Washington Post

The short answer:  because the modern, politically engaged, American evangelical typically has views that are not really Biblically based at all - except when it comes to homosexuality, I guess. 

On the other hand, NPR has an article about some evangelicals who are saying they can't in good conscience vote for Trump.

Letting Laffer off lightly

Cutting taxes to balance the budget? You're having a Laffer - The Drum (Australian Broadcasting Corporation)

It seems to me that when journalists here write about Art Laffer, they tend to let him off pretty lightly.   (Kansas rarely gets a mention, strangely enough.  How's it going?  - still terribly, I see - you have to go to somewhere like Forbes to find a "free market" proponent to run the Laffer line that it'll all work out for the good - just you wait and see; give it a decade or so.  Oh, and universities and highway funding - who needs them? It's all a "spending problem", not a revenue one.  Lol.)

But nonetheless, Ian Verrender's explanation of what's happened with low interest rates (companies are paying out big dividends, while simultaneously having earnings decline) was interesting.

My duty to note Spielberg

A Word With: Steven Spielberg - The New York Times

I will read, and usually post about, any Spielberg interview I find.   As usual, he presents as the smart, self aware, and very likeable man I've always perceived him to be.

I see that The BFG seems to have received enough positive reviews at Cannes (well, it seems to me the British press were kinder to it than the US media) to ensure it will be a success.  

Trust me, I'm a business man

So, a high profile business man is not only able to completely misrepresent and massively exaggerate about a Labor Party policy, but he's also able to completely and utterly backtrack on a former position? :

 

That's what self serving business men do, hey Symond?  

Interesting...

Peta Credlin suggests government lawyers said boat turnbacks were illegal | Australia news | The Guardian

I'm not surprised:  advice given to Labor governments about the likely illegality of the practice would not have changed.

In my opinion, Australian journalism has been far too supine in accepting the Coalition government's refusal to discuss "on water" or "operational" matters.  And unwilling to spend the money to find out the fate of some returnees. 

Deep thoughts for a Monday

Physicist Bee H tweeted a link to this interview, so I presume she found it interesting.  Here's the best part:

Seeing as you’re a physicist who has thought so deeply about Gödel’s theorem, do you think the absence of a theory of everything in mathematics suggests there might be no theory of everything in physics?
I totally think about that. Why should we think, since physics is so rooted in mathematics, that there is going to be a physical theory of everything? The way we usually think about the Big Bang is: The universe is born, and it’s born with initial data. There are laws of physics, and somehow the initial data is just… something else. We really are dishonest about where that comes from. What if the law of physics that describes the origin of the universe is something that has to make a claim about itself, which is a classic self-referential Gödelian setup for a tangle. [A Gödelian tangle is an unprovable, self-referential mathematical statement, such as, “This statement is unprovable.”] What if the laws of physics have to make a claim about themselves in such a way that they themselves become somehow uncomputable?

I’m also super interested in the idea that the initial data of the universe could contain irrational or uncomputable numbers. Then the universe could never finish computing the consequences of the initial conditions. Maybe we can’t predict what’s coming next because every digit of the initial data is a toss of a coin.

But it’s not enough if I only have words, and I’ve never found something to write down in math, so I’ve just kind of waffled. I think a smart thing to do would be to look at a specific Gödelian tangle that exists in mathematics and try to map that to fictitious laws of physics. Then you would have a universe in which there was a Gödelian tangle. There are constructive things to try.

Just plain nuts

TLS | Otter ego

Is this to be taken seriously?   Sounds more like an April Fool's joke.   But if not, seems to me that this piece would be more appropriate in The Guardian as an example of self indulgent eccentricity, but here it is in the Time Literary Supplement.  An extract:

The real novelty of Foster’s approach, however, lies in his second
instrument. Foster is going to inhabit – not just imaginatively but
physically – the landscape of his target animals. He exchanges
hallucinogens in the living room for adoption of the lives of the
badger, the otter, the fox, the red deer, and the swift.

Foster is not someone who believes in half-measures. To replicate the
life of a badger, Foster and his eight-year-old son live for several
weeks in a “sett” – more accurately a hole in the ground gouged by the
JCB digger of a farmer friend – in the Welsh Black Hills. Like badgers,
they sleep in this sett by day, and crawl around the forest on their
bellies by night, eating worms, grasshoppers (and lasagne provided by
aforementioned farmer friend), licking slugs and smelling their
surroundings (they even construct a scent map of the forest). Over the
weeks, the importance of vision, in this new, dark, ankle-high world
they inhabit, is progressively replaced by hearing and smell.

If anything, Foster’s approach to being an otter is even more
demanding. Spraint is otter dung – used to mark their territory and
often deposited in highly visible locations, such as the rocks beside a
river pool. Foster enlists the help of his children, encouraging them to
deposit their own “spraint” along the riverbanks of Devon. They all
then learn to identify, using their olfactory abilities, each other’s
spraint, assigning individual piles of it to individual persons. Foster
completes his inhabiting of the life of an otter by sleeping in storm
drains by day – nestled warmly in a bed of nappies and syringes – and
swimming in the rivers of Dartmoor by night, attempting, unsuccessfully,
to catch fish with his teeth.

Update:  Ha!   I just click over to The Guardian, and what do I find?   Another story, this one about a British guy trying his hardest to become "goatman"!:

Thwaites spent three days in Alpine meadows, doing his best to mix with a herd of goats. “No one was using that much energy, there weren’t wolves around, we weren’t being driven along a mountain path, but it was still difficult, especially going downhill,” says Thwaites. “After a while, the prosthetics started rubbing, and I got sweaty and cold.” This physical discomfort “encroached” on his attempts to think like a goat.

Is there something in the water over there that the government ought to be looking into?
