Logic in history

I've never been that interested in logic as a topic per se, and this article on the rise and fall of logic in history helps explain why. 

It's a good read, although my impression was that such a survey should include a reference to Wittgenstein towards the end...

Opposite conclusions about renewables

There was a really good explanation on Radio National's breakfast show this morning about how the complicated effect of renewable energy on Australia's electricity costs is capable of being interpreted completely differently by the Right and the Left. 

Unfortunately, there is no transcript, you have to listen to the interview.  Well worth it, though.

For economics graphs lovers

I think I spotted this on Twitter - Piketty and others have launched a the World Wealth & Income Database which lets you look at, and fiddle with, lots of graphs, such as these:






The graphs for Australia, unfortunately, currently don't seem to allow for the same comparisons.

But those US graphs are pretty startling...

About cava

I've taken to trying the cheap-ish Spanish cava available at our run-of-the-mill liquor outlets, and I have to say, it compares very favourably to cheap Australian sparking wines, and might even be more enjoyable than your standard, cheaper genuine champagnes.

(And by the way, the sequence in Travel Man when they have a cava tasting session in Barcelona, is a very funny bit of television.  In fact, the whole episode is one of the funniest in the series.) 

Just wanted to pass that on...

A tricky issue

Well, this is a tricky issue to deal with.

Is watching porn in public properly viewed as harassment?  

I am sympathetic to the feminist view expressed here that it virtually is, yet at the same time, it seems to me that a nation that tolerated the page 3 topless model in its national daily press for so long only has itself to blame.  

But yes, lines have to (or should) be drawn somewhere, for the sake of civil society, and moving up to watching sex on public transport, within proximity of any other passenger, does deserve a special offence of its own, as a form of public nuisance, I reckon.   Perhaps the first step ought to be the right to require them to leave the public space, but if that fails, the back up of potential prosecution is warranted.  I think.  

CGI agreement

Further to my post about Rogue One - I see that Guardian readers by and large agree with me that the digital resurrection of Peter Cushing (and Carrie Fisher) was not entirely convincing.

Normalising STDs

Slate has an article about rising rates of sexually transmitted diseases in the US, particularly amongst gay and bisexual men, and looks at the question of whether the problem is that those groups have normalised catching STDs as "no big deal" (as well as the carefree attitude towards use of condoms that the Truvada HIV prophylactic drug encourages.)

At the end of the day (and a tad disappointingly for my conservative attitude against promiscuity), the gay writer ends up making the case that the national increase is driven more by a combination of budget cuts and closures of sexual health clinics and conservative attitudes towards restrictive sex education in the red states.

I feel I need more information to be entirely convinced...

How climate deniers are fooled

Good post at Real Climate about how climate change deniers are willingly fooled by charlatans. 

Unfortunately, it seems that once you reach a certain age, having been fooled for years becomes psychologically an impossible admission.  Hence, if you're talking fervent denialists above the age of (roughly) 65 or 70, it seems we're just going to have to wait til they die out rather than continue to try to convince them.    

Anyway, here's a key chart from the post that (maybe) I've posted before?:

As the Real Climate post says about it: 
If climate scientists were trying to exaggerate global warming they’d show you the unadjusted raw data!

Ancient waters

This factoid turned up somewhere I was browsing recently, although I see it first got publicity back in 2014.  Not sure, but I think I missed it then.  Here it is:


Which has the odd implication, I suppose, that truly ancient urine is created every day by everybody. It's the sort of science thought that might impress Donald Trump, perhaps?

Another movie review you don't need

Watched 2013's Now You See Me on free to air TV last Friday.   Some observations:

*  talk about your "high concept" movie with a simple pitch:  rogue magicians do bank heists live - while performing in front of an audience!  Cool!  
*  talk about your "high concept" movie that fails to convince:  all flashy, swirling camera movement;  but wildly improbable and complicated plotting with really terrible characters .  Does any character in this movie reach any level of likeability?  Barely.
*  Woody Harrelson in particular - an actor who has evolved from "likeable doofus" to "smartass with a face that's just begging to be smacked".   OK, so his character was meant to be annoying, I think.  But unfortunately, his face and manner just fits that role too well.
* how did it get a sequel??

Prepare ye the way of the ....

That's interesting.  (The astute reader might consider this redundant - I pretty rarely post items that are not of interest to me.) 

I didn't know that it's now believed that exposure to semen prepares a woman's body immunologically for pregnancy:
Seminal fluid contains small molecules that act as biological signals. Once deposited in the vagina and the cervix of a woman, these persuade the woman’s immune system to adopt a profile that tolerates (that is, recognises and accepts) sperm proteins known as “transplantation antigens”.

The tolerant profile matters if fertilisation takes place. Immune cells recognise the same transplantation antigens on the developing baby, and so support the process through which the embryo implants into the wall of the uterus and forms a healthy placenta and fetus.

So over time, repeated contact with the same male partner acts to stimulate and strengthen a tolerant immune response to his transplantation antigens. The immune system of a woman responds to her partner’s seminal fluid to progressively build the chances of creating a healthy pregnancy over at least several months of regular sex.
And here's some strong sounding evidence to back this up:
Preeclampsia is more common when there has been limited sexual contact with the father before pregnancy is conceived, and is associated with insufficient establishment of immune tolerance in the mother.

The length of time a couple have had a sexual relationship seems more important than the frequency of intercourse. In a study of first pregnancies in 2507 Australian women, around 5% developed preeclampsia. Affected women were more than twice as likely to have had a short sexual relationship (less than six months) compared to the women who had healthy pregnancies.

Women with less than three months sexual activity with the conceiving partner had a 13% chance of preeclampsia, more than double the average occurrence. Among the few women who conceived on the first sexual contact with the father, the chance of preeclampsia was 22%, three times higher than the average. Low birth weight babies were also more common in this group.
 Although its frequency seems not so important for preeclampsia, the article notes that sex around the time of using IVF does help:

Combined data from more than 2000 patients across seven studies showed the occurrence of a detectable pregnancy increased by 24% after vaginal contact with seminal fluid near the time of egg collection or embryo transfer. A study of Australian and Spanish couples showed intercourse in the days just before or just after embryo transfer boosted pregnancy rates by 50%.
I guess this suggests that couples who want children in the future may be better off in the long run to not rely on barrier methods only as a contraception.   Good news for men, at least...

The Rogue and the detective

I finally caught up with Rogue One yesterday.

I think it's very competent, and very watchable, perhaps without being particularly memorable.   But I want to comment on a few things:

*  I felt there was still a clear bit of the "uncanny valley" going on with Peter Cushing's reanimated face.  Actors must be breathing a sigh of relief that the process of even attempting their replacement via computer  is still complex, expensive and not completely convincing if it lasts more than a very brief period.

*  the creation of very realistic looking alien landscapes in this and The Force Awakens, on the other hand, is so much noticeably better than it was in the 3 prequels, where everything looked fake in a Lord of the Rings way.

*  the rehabilitation of the Force as a spiritual thing, rather than Lucas's stupid suggestion that it was just biology, continues apace, and that is a good thing for the series.

*  the android K-2SO's design reminded me a lot of the robots in Miyazaki's Laputa, and (of course) I'm not the first person on the internet to notice that.

Then last night we watched the second episode of Sherlock's latest (and last?) series.

I thought it was terrific, especially after the pretty woeful first episode.  (My son even indicated he had sort of lost interest in the series after that one!)   Seems to me to some sort of redemption for Moffat's writing abilities, too, of which I had become very skeptical.

OK, there was one plot element that was kind of silly and contrived, but I see that many commenters at The Guardian said it was a clever update on the original Conan Doyle story, so perhaps the memory wiping drug was key to that, too.

But it was fantastically directed, well acted, full of funny surprises, and set up the show for many potentially big reveals in the last episode.   I hope that lives up to the high expectations everyone will now have.

If you ask me...

...there is really surprisingly little media commentary given to the fact that Trump blond dupe Kellyanne Conway seems to constantly be trying to run lines with the press which are either subsequently contradicted by her boss, and/or shown to be wrong.  (OK, there has been some media commentary on Conway contradicting herself - but it goes much further than that.)

The only I thing I can put this down to is that the Trump transition is so shambolic, the press just can't spend time on every weird contradiction or event - there are just too many to cover.  And they all know Trump just denies inconsistencies and thinks that's all he has to do.

Spielberg considered (again)

There's a new book out on Steven Spielberg that's been getting favourable reviews, partly because it's by a Jewish feminist, so her background brings something a bit novel to the exercise.

For a bit of a non-review that nonetheless gives a decent run down of Spielberg's life, this New Yorker article is not bad.  The New York Times book review is, however, more a review.

Updates on Trump in Russia you may want to read

Three things:

* Did you wonder how Pravda reported on Trump's adventures in Russia?  As it happens, they did it running a dismissive, let's all laugh at how ridiculous Americans are, column headed "The Adventures of Donald Trump at Moscow's Ritz Hotel".   And here's the oddest section: 
Generally speaking, American policy makers have a serious obsession about natural bodily functions. Last year, for example, it was reported that an unidentified individual, presumably a Russian intelligence officer, defecated on the carpet in an apartment of an American diplomat. Of course, no evidence was presented whatsoever.
Furthermore, continuing the "I think they protest-eth too much" line, it concludes:
The story has once again clearly shown the mental abilities of Hillary Clinton's supporters. The Democratic Party experiences a deep-rooted crisis indeed. In general, the story about the adventures of Donald Trump in Moscow's Ritz Hotel has already been recognized as one huge epic fake news both in Russia and in the United States.
Gee.  They write exactly how Trump talks.  Spooky.

* No 2's:   I see via Twitter that someone has turned up audio of Trump on a Howard Stern show from 2001 in which the other guest (who, apparently, had a girlfriend who Trump had "stolen" from him - ugghhh) said this:
After Trump bragged that he “took” Benza’s girlfriend, this happened:
Trump: I assume A.J.’s clean. I hope he’s clean.
Benza: Meanwhile, he bangs Russian people…
Stern: Russian people?
Trump: Who are you talking about, Russian people, A.J.? I don’t know anything.
Benza: He used to call me when I was a columnist and say, “I was just in Russia, the girls have no morals, you gotta get out there.” [Trump’s] out of his mind.
Trump did not deny making the statement.
 The site has the audio of the interview up, and to be honest, it's not clear that Trump heard what Benza was saying about what he [Trump] had said about Russia "girls".

But it certainly helps reinforce the (unsurprising, of itself) likelihood that Trump has had slept with Russia women, if not prostitutes, on (more than likely) more than one occasion.

The question is - was it recorded by Russians and, even then, is the content enough for it to be bribe capable?

*  The use of sex tapes for political purposes in Russia was in the news only last year.  In a story that I certainly don't recall noticing at the time, Putin was accused by a political activist:
Natalia Pelevina, a Russian political activist at the heart of a shocking sex scandal, has no doubts about who is responsible for revealing her affair with a former Russian prime minister.
A secret video of her and Mikhail Kasyanov showing intimate bedroom sex scenes and frank private conversations was baldly exposed last Friday on national television.
Pelevina is convinced the Russian security services planted the recording devices to entrap the couple at the behest of the president.
"It had to be Putin. I have no doubt about that," Pelevina told CBC during an exclusive interview in Moscow this week.
She hadn't spoken publicly about the sex scandal since it broke last week. Kasyanov is chairman of PARNAS, a liberal opposition party in Russia. Pelevina is his political assistant and was, until this week, a member of the party executive.
Russian broadcaster NTV aired a 40-minute special program liberally laced with scenes from the secretly taped video of the two.
But as for Putin's direct dirty hands in the use of sex tapes,  we go back to 1999:
Out of nowhere, a shocking video appeared on a Russian TV news program late one evening in March 1999. A surveillance tape showed a naked, middle-aged man who resembled Russia's top prosecutor, Yuri Skuratov, cavorting with two unclothed young women. Neither was his wife.
The ensuing scandal included a press conference by the head of Russia's FSB security service at the time, Vladimir Putin, who made clear it was Skuratov in the video.
Skuratov soon lost his job, not to mention his dignity.
President Boris Yeltsin was apparently impressed with Putin's handling of this episode. Yeltsin wanted to get rid of Skuratov, who was believed to be looking into Kremlin corruption. Several months after the video surfaced, Yeltsin named Putin to be prime minister, and a few months after that, Putin took over as president.
It is therefore completely plausible that, if he knew it was potential useful, Putin would give the nod to taping  Trump if he was silly enough to be engaged in any form of sex (without his wife) in Moscow in  2013.

As I don't doubt he is silly enough, the main question is likely - did they?



A Great Moment in Science


As this interesting post from Discover explains, it was not until 1 January 1925 that it was really "official" that Hubble had confirmed that the Andromeda and other spiral "nebulae" were really galaxies a very long way away.

It's extraordinary to think we not quite 100 years into a proper understanding of the size and nature of the universe.   (And barely 150 years into Darwinian evolution.)

No wonder humanity is, in a sense, still adjusting to all this.   


To my sometime twitter troll

*  I didn't even know what Pseud's Corner was: had to Google it.

*  I generally eschew comment on MMA:  I assume I would be appalled if I looked into it in too much detail, so I don't bother.  Instead, I get my daily fill of "appalling" by checking Catallaxy.

Weird judgement on display, again

I might have guessed.  Despite being no pro-Trumper in the lead up to the election, Sinclair Davidson can't seem to stop himself getting a vicarious thrill whenever a politician (or at least one vaguely on the Right) behaves belligerently to the media or a political opponent.  Remember - he was one of the very, very few people in the land who  thought Bronwyn Bishop's aggro, hopelessly partisan time as Speaker was actually praiseworthy.

Psychoanalysis via blog posts may not be a reliable exercise, but I continually get the feeling that SD is frustrated that he personally doesn't get the chance to be as rude to people to their face as he would like to be.   Or a frustrated wannabe tough cop (or soldier) on a loose leash to clean up a bad part of town - that kind of thing.  

The title of his post on Trump and CNN is particularly confusing: CNN has been caught out.

"Caught out" doing what, exactly?   Correctly reporting that briefings about serious claims about Trump being compromised by the Russians - or his team co-operating with them for election intel - had been made?  

I think the theory that Trump didn't even realise the distinction between what CNN reported, and what Buzzfeed did, has plausibility.  

Tillerson & China

A reasonable sounding bit of commentary from The Interpreter about Tillerson sounding gung-ho about China in the South China Sea. 

Not sure of the value of this..

Nature has a story with the science fiction friendly title: 


Now, while I don't want to come across as a PETA softy, but the details of this experiment make me doubt somewhat whether its scientific benefits make the treatment of the mice worth it.  (I say that, though, very unaware of the treatment of lab mammals, generally.  There are probably far worse examples.)   

My feelings about animal experimentation are still influenced somewhat by the anti-vivisectionist sentiment and argument of CS Lewis.  You can read about that here.
