Backreaction: Sorry, the universe wasn’t made for you

Here's a post by Bee H about the anthropic principle, and objecting to the idea that the universe was "fine tuned" for life.  

Lots of false equivalence noted

The media’s coverage of NBC’s Trump-Clinton forum was a disaster.


Donald Trump's proud ignorance reveals his contempt for the presidency


Fear of a female president


Last night, Clinton got 6 questions on her emails. Trump got zero on his Iraq lies.

A look at an obvious Trump feature

Donald Trump’s Shortest Attribute Isn’t His Fingers - POLITICO Magazine

Lots of evidence provided from lots of people that Trump has always had a very, very short attention span. Given that there have been many examples from the campaign where can barely articulate a thought in a full sentence before going onto some other thought, this is far from surprising.

I also see that Snopes has already called out as false the conspiracy  theory (promoted on twitter by actor James Woods, of all people) that Clinton was wearing an ear piece yesterday.

She may be reluctant to give them the attention they crave, but I don't think it would hurt Clinton to go in, boots and all, in calling out a substantial slab of Trump's supporters as being reality challenged, very gullible people who need to get a grip.

How about playing the tape to him at the Presidential debate?

Donald Trump just lied about opposing the Iraq War before it started. Here’s proof. - Vox

The article notes that there is a recording of Trump saying in 2002 (without much enthusiasm, but still) that he supported the Iraq War.

The rest of the article bemoans how the media knows that a serial repeat liar who continues repeating a lie, will more or less get away with it.

But really, why should this be:  why cannot a reporter play the audio to his face and say "why have been repeatedly lying about this?"  Why not do it as part of the Presidential debate - just play the tape, and see how he tried to deal with it?

 

The "no jack" scandal (talk about your First World problems)

Funny to read this wanky, typically Apple, explanation noted at Slate about why the new iPhone has no ear phone jack:

Apple’s own explanation for the change was a little baffling. Schiller said the rationale for jettisoning the headphone jack could be summed up in one word: “courage.” What kind of courage? “The courage to move on, and to try something new that betters all of us,” he elaborated. OK then!

Further down, it is said that there is something the phone gets from not having one:

Well, for one thing, you can now drop your iPhone in the toilet. I mean, you could do that before, but now when you get it back out, there’s a decent chance it will continue to function. Eliminating the headphone jack enabled Apple to seal the phone at last, making it “dust and water resistant,” albeit not fully waterproof.

But wait a minute - the Samsung Note 7 (yes, I know - it can explode) has been heavily promoted as being waterproof to a similar degree, and it has an audio jack.

Why is Apple not able to use a similar water resistant jack?

I'm still sticking to my Samsung allegiance - even though my first experience with their cheap, early Tab 2 tablet was not great.  (Known bugs that were never fixed with any update.)  It's been made up for by my very, very pleasing Tab S, and a cheapo phone that is still pretty damn reliable.  I always have liked the look of the round edged Galaxy 7, too, but I'm not willing to spend that much on a phone.

Only 104 years ago

Once you get past 50, events that happened 100 or so years ago no longer sound all that far in the past.  Only twice your lifetime...that's not so long ago!

So, as I was walking around the Rydges Hotel at the Exhibition grounds last Saturday (it's my routine now, and I really like its Paddock bar for coffee or, later in the day, their house beer), I noticed this metal history note around a tree:

The first flight in Brisbane was "only" 104 years ago at the Exhibition grounds.   This deserves a look at a real photo of the event:

Not the best photo to see what's going on, but what I like the next one is that you can clearly see the grandstand that is still there, and within sight of the Paddock bar.

The State Library blog post that I got these from notes that the plane crashed on landing. "Wizard" Stone was OK, though.

Incredible to consider the advances in aviation since then. 

Resistance to weed

In Colorado, a revolt against legalized marijuana - The Boston Globe

I'm not at all sure, of course, that the local anti legalisation activists are credible in all that they claim, but that said, I understand opposition to things like this:

She hates that her kids’ school is near several dispensaries. She’s
frustrated by the full-page ads in the local paper with huge photos of
buds and coupons for $1 joints with a purchase of $20 or more. 

Yes, surely a large part of the potential problem with legalisation is the accompanying capitalist urge to expand the market.   If it were ever legalised here, I would certainly hope that it is the subject of severe advertising restrictions of at least the same severity that tobacco faces.   Apparently, the Americans couldn't see their way to do that with marijuana.

There are also claims in the article that the period of legalisation has been accompanied by an increase in youthful homelessness - something you might expect to see in increased cases of schizophrenia that is likely to accompany increased youthful use.

Political correctness and the Republicans

Conservative Movement & Republicans -- ‘Establishment’ Is Only the Beginning of Their Problems | National Review

Gee, here I am recommending an article at National Review.  I thought this part was especially true:

There’s a lot to be said for refusing to be hemmed in by political
correctness, but we’ve gotten to the point where many conservatives have
embraced the idea that if political correctness is bad, then anything
that’s politically incorrect must be good. This has created an
environment where saying foolish and inflammatory things can be a major
career enhancer for conservatives. If you can say something that makes
liberals talk about how much they hate you, but conservatives won’t walk
away even if you make them cringe, that’s a recipe for selling books
and getting on TV. This may be great for the careers of a few people,
but it also gives the public at large a terrible impression of
conservatives. Even if they say some things you agree with, the last
thing that anyone who cares about the conservative movement should want
is for the public to base its opinion of it on people who are trying to
offend as many people as possible to get attention.

The moral panic continues

Under the odd headline which seems to me to be somewhat of a failure if it's meant to conjure up moral outrage (Schools told to teach kids that sex varies like the weather), I see that The Australian, and some politicians, are doing their best to drum up a moral panic over the fact that some sex education material now refers to the (rather obviously true) fact that some people over their lifetime experience somewhat varying sexual preferences:

Education Minister Adrian Piccoli yesterday ordered his ­department to withdraw the ­sexual and gender diversity ­resource for teachers, which ­appears to have been heavily based on the Safe Schools program. Alerted to its existence by The Australian, he said he was “very angry” the resource had “got out”. “I have directed the ­department to take it down ­immediately and review the ­material and all links,” he said.
“Safe Schools materials are only to be used strictly in accordance with the revised guidelines established by the federal ­government. I am furious this policy has not been adhered to and have demanded a full explanation from the (departmental) secretary.”
Launched quietly this year, the 17-page teacher toolbox for delivering content relating to ­diversity of sex, sexuality and gender contains a list of resources the educators can refer to in their teachings. One recommended activity invites Year 10 students to consider a range of characters, such as “Joseph”, who is married with three children but “when he masturbates, fantasises only about men” and “is attracted to several of his male friends” and “Alex”, who had sex with girls as a teenager but developed a relationship with a man after moving to a country town.
Students are asked to determine each character’s sexuality and whether they fit into ­“traditional binary thinking” ­regarding sexuality.

Given that it's rather likely now that in any given school of significant size, there is going to at least one  kid who has a parent who has moved into a same sex relationship (after a heterosexual one), I find it rather difficult to see how the material quoted there is doing much more than confirming what a lot of kids already know or guess sometimes happens.  (And it's also worth noting again that just because something is suggested in a teacher's manual does not mean that teachers will use it in exactly that fashion.  Hence, I wouldn't be surprised if many don't refer specifically to what the "Joseph" fantasises about, for example.) 

As I have suggested before, acknowledging that bisexuality (or fluid desire?) exists does not even necessarily imply support for same sex marriage - if we're going to be like ancient Greeks and Romans, who had little problem with sexual desire for some being "non binary",  a modern person can also take their view that marriage is primarily about heterosexual reproduction, and no matter that some people fall in love with people of the same gender, the State or society has no particular interest in recognizing those relationships as "marriage".

A simple suggestion

As much as the Trump supporting Right is the dumbest and most gullible block of voters since, well, I don't know that I can think of any valid comparison in my lifetime, the news playing up Hillary's recent coughing is, unfortunately, something she should address.

To me, it usually has sounded like a simple case of a cough induced by post nasal drip, which is nothing to write home about.  But we're talking image here, as well as the stupidest political movement in history, and I would suggest she simply has her doctor talk about it, noting that it is not serious, and that Right wing nut jobs talking about her virtually being on her death bed are being ridiculous.

Prion diseases discussed

When People Ate People, A Strange Disease Emerged : The Salt : NPR

I didn't realise that the PNG highland matter of cannibalism of the dead used to be so, um, thorough:

As one medical researcher described, "If the body was buried it was eaten by worms; if it was placed on a platform it was eaten by maggots; the Fore believed it was much better that the body was eaten by people who loved the deceased than by worms and insects."

Women removed the brain, mixed it with ferns, and cooked it in tubes of bamboo. They fire-roasted and ate everything except the gall bladder. It was primarily adult women who
did so, says Lindenbaum, because their bodies were thought to be capable of housing and taming the dangerous spirit that would accompany a dead body.

"So, the women took on the role of consuming the dead body and giving it a safe place inside their own body — taming it, for a period of time, during this dangerous period of mortuary
ceremonies," says Lindenbaum.

But women would occasionally pass pieces of the feast to children. "Snacks," says Lindenbaum. "They ate what their mothers gave them," she says, until the boys hit a certain
age and went off to live with the men. "Then, they were told not to touch that stuff."

Foreign Correspondent on China's kids

What a sad episode of Foreign Correspondent last night, looking at the issue of Chinese kids, particularly in rural areas, left in the care of grandparents (or other relatives) while their parents move away for years at a time to work in city areas.   And, of course, this does not always work out.

By the way, is it just me, or does it seem to others too that rancorous arguments within Chinese families sound like some of the nastiest you'll ever hear?  It seems that if kid's don't live up to expectations, they'll be really demeaned for it.

Well, this hardly seems fair...

Is sex in later years good for your health?: Having sex frequently - and enjoying it - puts older men at higher risk for heart attacks and other cardiovascular problems. For older women, however, good sex may actually lower the risk of hypertension.

That's according to the first large-scale study of how sex affects heart health in later life. The federally funded research, led by a Michigan State University scholar, is slated to be published online Sept. 6 in the Journal of Health and Social Behavior.

"These findings challenge the widely held assumption that sex brings uniform health benefits to everyone," said Hui Liu, MSU associate professor of sociology.

Liu and colleagues analyzed survey data from 2,204 people in the National Social Life, Health and Aging Project. Participants were aged 57-85 when the first wave of data was collected in 2005-06; another round of data was collected five years later. Cardiovascular risk was measured as hypertension, rapid heart rate, elevated C-reactive protein and general cardiovascular events: heart attack, heart failure and stroke.

Older men who had sex once a week or more were much more likely to experience cardiovascular events five years later than men who were sexually inactive, the study found. This risk was not found among older women.

"Strikingly, we find that having sex once a week or more puts older men at a risk for experiencing cardiovascular events that is almost two times greater than older men who are sexually inactive," said Liu. "Moreover, older men who found sex with their partner extremely pleasurable or satisfying had higher risk of cardiovascular events than men who did not feel so."

Fear of not dying

Apeirophobia: The Fear of Eternity - The Atlantic

What a great article here, about people who get all anxious and sweaty at the idea of living forever in heaven.

Just goes to show, there's no pleasing everyone.

The article does go on to explain, however, that it is related to the fear of infinity, or at least vastness, as explained in this paragraph:

There shouldn’t be too many atheists who fear of eternity, since they
reject the idea of an afterlife, Wiener says. But that doesn’t mean
that those who aren’t religious are immune to existential anxiety.
Infinity, after all, doesn’t pertain only to time; it can also apply to
space. “I feel that we are all insignificant compared to the universe,”
wrote Jamie Adkins, a nurse and longtime friend of mine, in response to
my Facebook post. “When I start to think beyond our solar system, it is
as if my thoughts automatically stop to protect myself from having some
form of a panic attack. The knowledge of black holes will give me
nightmares for days. The thought of the distance between galaxies is
unbearable.”

She likened the experience to Horton Hears a Who. “We are on this tiny flower and can be blown away any second.”

Yeah, I did have a brush with that, once, when I was around 7 or 8.  As I recall, a brother who had gone to the Council library when I couldn't borrowed a book for me, and it was one about space or astronomy, but was primarily about galaxies and the vastness of the universe.  There were lots of pictures of galaxies.   It actually upset me, because it conjured an image of such cold, lifeless, vastness in my mind.  My brother was puzzled, saying he thought I liked books about space (and I did - this was the era of Apollo and I followed it very closely in the papers and on the news.  I also read kid's science fiction, of which there was a lot - all of it optimistic - in that decade.)  But what I liked was the idea of life in the universe, making it home.  And I still do.

But as for heaven:  well, I think right from early childhood I've accepted the view that it's a basically unknowable thing: to be experiencing something like life but without the cycles, limitations and uncertainties with which we know it on Earth.  Reunion with loved ones (at least initially) has become a widely accepted part of the commonly believed experience of it, and who (or at least, the majority of people who have loving relationships during their life) can object to that idea?   As for what goes on for the rest of eternity:  who knows;  does  the ego continue indefinitely, rather than being subsumed into a greater thing sooner or later (or even temporarily.)   I don't mind the idea that you can spend a hell of a lot of time observing (or influencing) life on Earth, or in other parts of the Universe. It can all be fun to imagine, but it's unknowable. 

As I said recently, this is a positive feature of Christianity, not a bug.  Keeping it vague and unclear is actually a good thing, if you don't want people doing all sorts of evil things on Earth with the justification that it'll all be sorted out in the afterlife.
