Where is that expectation wrong?
Well, I knew she would have to be doing this soon, given the recent arXiv paper in which she was a co-author. Here's Sabine Hossenfelder trying to explain superdeterminism and her expectation that it
solves all quantum oddities:
I don't understand the issues fully, but my impression is that Sabine underplays the philosophical significance of it. I wonder what other physicists think. (To give more detail: she seems to make an argument that it has no "real" implication at the macro level - but I am not sure that's right...)
Update: from comments following the video on Youtube, I pick out a couple that deal with the retro-causality interpretation, which she never mentions:
Before measurement of the particle in the double slit experiment, it is non-localised in time, it literally occupies all possible positions starting when it was emitted up to the point it is observed. This is how a single particle can go through both slits and interfere with itself. After it is observed, it becomes localised in time and acts like a single particle, not a wave. This is why observing before the slits eliminates interference, and does not if you observe afterwards. The crazy part is that the act of observation retroactively affects the past. If you observe before the slit, you do not get interference. If you observe afterwards, you get interference. This is because the wave collapse propagates backwards to the point the particle was emitted. Particles moving forwards and backwards through time acting like a wave, until the point they are observed at which point they never moved forwards and backwards through time in the first place and were always single particles, explains all the 'spookiness' and also explains that the hidden variables are hidden in time and as entities moving linearly through time we will never be able to observe them. Once you get your head around this concept, the weird behaviour of particles in quantum mechanics becomes obvious and logical.
Mind you, the commenter was "Microdoser", so I'm not sure I should trust him (or her) given my skepticism about that practice.
Another one:
I would add that many physicists assume entaglement can only propagate forward in time. Basic time invariance says that entanglement must be able to propagate backward in time just as well as forward.And:
So Is Superdeterminism described more by the future affecting the past, or by particles/ wave functions reacting differently depending on what is around them and what they interact with? thank you for the video
Last one:
If the detectors are far apart, and they do influence the measurement, then there is fast-than-light effects happening. (aka "spooky action at a distance"). And maybe this is the misunderstanding in communications with Bell or Zeilinger. As far I understand, they assumed superdeterminism to be a loophole to remove non-locality, in the sense to say the detector isn't actually choosing the angle of measurement, randomly, but is deterministic as well, and the particles kind of "know" this. Bell even got so far as to take a photon from the cosmic background radiation to determine which angle to measure at, which would leave the entanglement of the detector all the way back to the big bang.. and thats what I think they called absurd in "no free will". Thus SD and keeping non-locality, yeah why not. No issue with it, it is supposed to fix non-locality, I really would like to see a backdown how it should work, without making the universe holistic (and thats where I said in effect destryoing non-locality all together). Honestly, I don't have an issue with real faster-than-light effects as long the "cosmic censorship" is somehow in affect that it doesn't allow information communication. So maybe the wave form is physically real (the so called particle is really smeared out) and maybe the collapse is really faster than light. And maybe in case of entangled particles the waves are really connected far apart until collapse. So what. If this is reality, I don't care if Einstein wouldn't consider it beautiful ;)
New research suggests that the Roman prefect Pontius Pilate is the one that built the Biar Aqueduct, the most sophisticated ancient aqueduct of the Jerusalem area. The study also uncovered the way the unique aqueduct was constructed.
The aqueduct is part of the ancient water system serving Jerusalem. Biar, the shortest of the aqueducts, brought water from a point south of Bethlehem to Solomon’s Pools. Other aqueducts carried the water from there to Jerusalem. The five-kilometer aqueduct includes the Biar Spring, an underground shaft tunnel running about three kilometers, a surface channel and dozens of piers used for its construction and maintenance....
Archaeologists exploring Jerusalem have known of the aqueduct for a good 150 years. It has been dated from the Hasmonean period, in the second century B.C.E., through Herod to the late Roman period of the second century C.E. Yechezkel’s team used carbon dating of plaster to suggest that the aqueduct was built in the mid-first century C.E., before the destruction of the Second Temple. They believe Pontius Pilate, the Roman prefect from 26/27 C.E. to 36/37 C.E., known for condemning Jesus to death, ordered its construction.It's from a Haaretz article, which is quite interesting.
The BBC reports on the new (Covid led) trend for outdoor dining in New York city, and its detrimental effects, including more rats than ever before.
The city's ridiculous garbage collection system gets plenty of mention too, but it would seem no one considers that a move to actually using bins with lids is possible. Surely more rubbish being put out in bins with lids helps limit rat access to it?
This movie trailer is getting a lot of positive comment - and I can understand why.
Yes, it's another "multiverse" themed movie, but (no insult to the new Spiderman, I do intend seeing it) it's good to see it being done with fresh new characters.
Children's deaths in the news are always distressing, but it feels particularly worse in the imagination when it happens while having innocent fun.
The news is going world wide, with the New York Times story indicating that this might be the biggest number of deaths from any "bouncy castle" accident. Ugh.
So a woman in a private hospital room is upset:
Cassie of Sydney says:
1. I was double jabbed by October 2021…the AZ vaccine.
2. As demanded by NSW Health and all NSW hospitals, prior to my admittance to hospital on Monday 6 December, on Friday 3 December I had my first Covid test ever. It returned negative.
3. Last Saturday morning, 11 December, before being transferred to another hospital, I had my second Covid test. It returned negative. I was transferred to my new hospital on Sunday morning 12 December.
4. On Tuesday afternoon 14 December, the first hospital rang the second hospital to tell them that I may have been in contact with someone who has tested positive for the Covid Omicron strain. The contact would have happened sometime Saturday afternoon. At about 4.30p.m. on Tuesday 14 December a nurse came in in protective clothing and performed a Covid test on me…..we are still waiting on the result.
5, So, since Tuesday 14 December, at 4.00 p.m. precisely, I have been isolated in my hospital room. I am not allowed to leave, no visitors. Nothing. The nurses and physio come in to the room attired in protective clothing….as though I have Ebola!
6. We are still waiting on the result of the first Covid test however I have been told that as a matter of security the hospital does a second Covid test, this will be one done tomorrow afternoon and sent off.
7. I will not know any result until at least Sunday….so I am locked in a hospital room until 19 December.
8. I ask genuinely….what was the point of getting jabbed?
9. There is no way…and I mean no way….that I will be having a third, fourth, fifth or sixth jab.
10. Given the above, as you can all imagine my mental health at the moment is not the best, I hope this doesn’t impact my surgical recovery.
11. I am very upset.
Considering that she has more privacy than most get in hospital, food made for her, internet access and help on call, going berserk over a 5 day period of relative isolation strikes me a pretty pathetic plead for victimhood by a woman whose constant angry on line presence I now consider due to a mental weakness. (She is getting plenty of support from the other tossers at Cathollaxy.)
Toughen up, dear....
(I can afford to be rude to her, as she has been endlessly rude to me when engaging directly with her on Catallaxy.)
How do people not feel furious at the anti-vax peddling Fox News and websites (including the Australian wingnut Christofascist ones) when you have credible and detailed reporting from actual hospitals about the crisis that the un-vaxxed cause?
Take this article, about the experience in Kentucky, from Bloomberg.
It just shows the power of relentless political/culture war propaganda to susceptible minds, doesn't it?
Update: just appalling. Fox News is a plain force for human suffering in the interests of a bunch of insane hypocrites making money:
I wrote 1,000+ words this morning on the new data about whether Omicron is truly “mild” or not. It might be, or its mildness might be a partial mirage created by the youth and broad natural immunity from previous waves that South Africa enjoys. The key point in all analyses of Omicron, though, is that a virus that’s freakishly infectious, as this one appears to be, needs to also be freakishly mild for there not to be a surge in hospitalizations and deaths. Assume that Omicron is half as lethal as Delta but, as some studies have indicated, four times more transmissible. We’d expect a virus like that to produce twice the death toll Delta did (at least in the non-immune population) despite it being technically “milder.”...
The insanely steep spikes we’re seeing in European cases may not be evidence of Omicron surging and replacing Delta but evidence of Omicron and Delta infecting different sub-populations at the same time. That’s the CDC’s nightmare scenario, that Omicron will hit here full force but won’t sideline Delta by doing so. Instead the two will circulate in tandem, sometimes infecting the same people, and creating a double-whammy wave of sickness with Delta patients suffering somewhat more severe outcomes.
If that’s true then Saphier’s advice is insanely reckless. She’s telling people, including unvaccinated people, to go out and have no fear when doing so risks exposing them to Delta, not just Omicron. What is she thinking? Can we maybe wait a month to confirm that the variant is nothing worse than the “sniffles” before giving this advice?
A good Allahpundit post at Hot Air. (The comments usually indicate he is despised by most of the site's readership. He is too reasonable for them.):
I can’t believe we’re more than a year removed from the election and efforts are still ongoing to convince people that a candidate who lost the popular vote in his first national run, never had 50 percent job approval as president, got impeached, helmed the country during a pandemic that killed hundreds of thousands of people, and was regarded as a boorish loose cannon even by his admirers might have legitimately lost to a well-known generic Democrat.
And not by a lot. By a few thousand votes in some states. Yet it seems unfathomable to some that it could have happened, starting with the man who lost.
The AP assigned at least eight reporters and many months of research across hundreds of local election offices to this impressive but totally futile project. They went district by district across Michigan, Pennsylvania, Wisconsin, Nevada, Arizona, and Georgia to see how many cases of potential voter fraud had been identified by local authorities in each. Were there enough suspect votes to account for Biden’s margin in any of them? Answer: Not remotely. “The disputed ballots represent just 0.15% of his victory margin in those states.”
Won’t matter. The point of the gassy conspiracy theories about rigged voting machines is that devotees realize piecemeal fraud could never happen to a large enough degree to flip a state unless it’s “Florida 2000” close, which none of the states won by Biden were. There has to be some unified field theory of massive under-the-radar vote-rigging in which ballots are switched en masse by the thousands or millions to explain those margins. That’s why all conspiracy roads ultimately lead back to Dominion and Smartmatic. Maggie Haberman is right, though, that the AP analysis is useful in one respect. It challenges the suspicion that laws that were relaxed during the pandemic to make voting by mail easier meaningfully increased the amount of fraud at the polls. They didn’t.
Even poor old JC from Catallaxy, and who continues to appear at fascist Cathollaxy (where he seems to think most of the other commentators are idiots, but he still hangs out there) believes that the election fraud was real.
I wonder if Sinclair Davidson, who seemed half convinced by dubious statistical mathturbation claims that the election count must have been fraudulent, still believes that. Since the downfall of Catallaxy, I don't know what he believes any more. I should check his twitter, I suppose, but I seem to recall it's a pretty dull read, and mostly talks blockchain crap.
An eye drop that improves close-range vision could make misplaced reading glasses less of an inconvenience for many of the 128 million Americans who suffer from age-related deficits in near vision. Vuity, which became available by prescription on Thursday, is a once-a-day treatment that can help users see up close without affecting their long-range vision.
“For anybody who doesn’t want to fiddle with reading glasses, this might be a really helpful alternative,” said Dr. Scott M. MacRae, an ophthalmologist at the University of Rochester’s Center for Visual Science. Dr. MacRae was not involved in the clinical trials for the drug, which was approved by the U.S. Food and Drug Administration in late October.
But the way it works sounds, well, a little dubious:
Vuity improves near vision by constricting the size of the pupil. “It makes the pupil small, creating what we call a pinhole effect,” that way reducing the amount of peripheral light that passes through the eye that can make it hard to focus, said Dr. Stephen Orlin, an ophthalmologist at the University of Pennsylvania Perelman School of Medicine.
Won't that mean it's harder to see in the dark? Yes it does:
Although the clinical trials did not report any serious side effects, 14.9 percent of subjects who took Vuity reported mild headaches, compared with 7 percent of subjects who took placebo drops. Up to 5 percent of subjects taking Vuity reported other side effects such as eye redness, blurred vision, eye pain, visual impairment, eye irritation and an increased production of tears.
Because the eye drops reduce pupil size, they also make it harder to see in the dark, so they are not recommended for people who drive at night or need to see well in low light for other reasons, Dr. Waring said.
I think I'll pass.
Not that I care about Sex and the City or its current sequel series at all (in fact, I pretty much consider it a blight on humanity that this set of characters ever existed), but I have been amused to read about how a fictional death could lead to much discussion about how dumb it makes the key character appear.
Read this amusing take on the matter (with expert opinion from a cardiologist) in The Vulture.
This article explores how local Chinese authorities employed various strategies to promote the Patriarch of Sanping’s cult in post-Mao China from 1979 to 2015. It argues that the cult of the Patriarch of Sanping became an invented tradition for expanded religious tourism in Pinghe County in Zhangzhou, Fujian Province. Local state agents employed various placemaking strategies to promote Sanping Monastery and endorse the deity’s efficacy, creating an opportunity for resources to be channeled from other parts of China, Taiwan, and overseas Chinese communities to develop Pinghe County. This study shows that, on the one hand, local state agents have propagated miracle tales to entice devotees to visit and make donations to this monastery while, on the other hand, they have courted scholars, journalists, and tour guides to generate attention and interest in the cult. Overall, this article demonstrates how local government placemaking and marketing strategies have contributed to the transformation of a Buddhist master from a local deity to a popular god in contemporary China.That's the abstract to an article in Critical Asian Studies: The making of a local deity: the Patriarch of Sanping’s cult in post-Mao China, 1979–2015.
In a Guardian story about a young-ish Catholic Spanish bishop who has given it all away to marry an "erotic novelist", the report ends on this note:
Novell, who has a degree in agricultural engineering and who was ordained in 1997, is now reported to be working for a company that extracts and sells pig semen.
A tea cup reading fortune teller of young Novell would have had quite the interpretation challenge.
Update: today I learned that tea cup/tea leaf/coffee grounds reading has a fancy name - tasseography.
* Ate a very delicious yiros (lamb and haloumi) that made me think that is the best thing you can have at Greek cafe. (But don't get me wrong; Greek food remains a basically uninteresting cuisine.)
* Found out that Kmart can print photos on mugs immediately, if they are not busy (normally a next day service), and they cost $6. That seems ridiculously cheap.
* I didn't realise that Kentucky had a Democrat governor until watching the news of the amazingly damaging tornadoes. Of course, wingnuts are working themselves into a lather over any suggestion climate change has anything to do with it - and I remember some years ago Roy Spencer getting indignant that increased atmospheric temperature should mean less (from memory) shear winds (or something?), so he was upset that anyone was suggesting that big summer tornadoes were due to it. Others who make a career out of claiming climate scientists are exaggerating risk (Pielke Jnr) like to point out that the IPCC has said clearly that no trend is yet detectable. But obviously, that doesn't rule out a connection to an unusual event like the weekend's - just we don't know for sure yet.
I for one welcome our new furry overlords:
A man attacked by a pack of otters in a Singapore park has said that he thought he was going to die during the ordeal.
Graham George Spencer, a British citizen living in Singapore, said he was chased, pinned down and bitten “26 times in 10 seconds” by a family of otters while out for an early morning walk in the botanic gardens.
Spencer told The Straits Times he was approaching the gardens’ entrance on 30 November when he spotted about 20 otters crossing a path in front of him.
The animals were moving quietly but “went crazy” after another man ran towards them, Spencer told the paper. The runner was able to avoid the animals but Spencer was not as lucky.
He said they lunged at him, biting his ankles, legs and buttocks and causing him to fall over.
“I actually thought I was going to die – they were going to kill me,” he added.
Spencer’s friend, who was about “15 paces” away from him, ran up screaming in a bid to scare away the otters.
“I was bitten 26 times in 10 seconds. If it wasn’t for my friend, I don’t think I’d still be here. I’d be dead,” he told local outlet Today.
I'm trying to find a way to fit an insult to the British into this post too, without sounding too mean. It's not coming to me, so far.
