Some lunar oxygen calculations
An article at The Conversation explains how there's a lot of oxygen on the moon - unfortunately, all in the soil and needing a lot of heat to extract. But still, the maths are interesting:
If we ignore oxygen tied up in the Moon’s deeper hard rock material — and just consider regolith which is easily accessible on the surface — we can come up with some estimates.
Each cubic metre of lunar regolith contains 1.4 tonnes of minerals on average, including about 630 kilograms of oxygen. NASA says humans need to breathe about 800 grams of oxygen a day to survive. So 630kg oxygen would keep a person alive for about two years (or just over).
Only 800g of oxygen a day? I would have guessed it was more than that, probably influenced by things like the thought of the weight of a full scuba tank! Of course, there are going to be other gases involved too. The ISS has a 79% nitrogen atmosphere.
Anyway, more rough estimates from the article:
Now let’s assume the average depth of regolith on the Moon is about ten metres, and that we can extract all of the oxygen from this. That means the top ten metres of the Moon’s surface would provide enough oxygen to support all eight billion people on Earth for somewhere around 100,000 years.
This would also depend on how effectively we managed to extract and use the oxygen. Regardless, this figure is pretty amazing!
Indeed.
Precipitation issues in China
First: quite a lot of snow:
Another video of buildings not coping with it:
And an article in The Guardian about recent heavy rains:
‘It’s alarming’: intense rainfall and extreme weather become the norm in northern China
A European problem
The European Union brags that its climate ambitions are more aggressive than anywhere else in the world. There’s just one problem: If the world behaved like Europe, it would be burning an awful lot of wood.
Europe gets 60 percent of its renewable energy from biomass fuels, a process that uses wood scraps, organic waste and other crops to generate heat and electricity in specially designed power plants. U.N. rules allow the European Union to write off the emissions as carbon-neutral, so long as sustainable guidelines are met, even though burning the fuel can release more warming gases into the atmosphere than coal.
The European Union’s reliance on wood-burning energy to meet its climate goals — which include cutting greenhouse gas emissions 55 percent by 2030 — is a measure of the difficulty of making the transition to clean energy even on a continent where politicians have shown political will and enjoy significant public support for their green agenda. For now, much of Europe’s emissions reductions are being achieved by burning biomass instead of coal — and then not counting the resulting greenhouse gases, which critics say they should.
....
Excluding emissions from biomass can make a big difference. According to their official numbers, the European Union and Britain together reduced energy-related emissions by 26 percent between 1990 and 2019. Adding emissions from biomass makes the reduction 15 percent over the same period, according to an analysis last month from Chatham House, a British policy think tank. Britain — which left the European Union in 2020 — is a major consumer of biomass pellets, so the post-Brexit E.U. figures for biomass are likely to be somewhat smaller.

About dangerous crowds
Here's a good article at the ABC about the history and science of crowd surges, like the deadly one at the Travis Scott concert.
I think it clear that the most disconcerting thing about this one was the fans who were trying to get the concert stopped when it was clear a disaster was unfolding.
Trans reality
I didn't intend to, but I ended up watching about half an hour of the show on ABC "Girl Like You" last night. It was a documentary, made over many years, watching a young trans guy and his girlfriend dealing with his transition.
I didn't get his full background, and I have to say, as documentary it was very heavy handed.- lots and lots of music made to flag the emotions on display. And as with all "fly on the wall" documentary, I do wonder what influence the presence of the documentary makers have.
I also wondered why it was being pretty heavily promoted, but only being show in a pretty late time slot.
I suspect the answer is that because the story wasn't as positive about the whole trans experience as might be expected from the very queer friendly ABC. The story seems to be that his girlfriend thought their relationship could survive him transitioning, and it turned out it couldn't. She broke it off, abruptly, but it was clear that she had felt the whole experience of supporting her former boyfriend very draining.
As for the transition - it looked like he had not had the operation, just a lot of chemical treatment. And they made the point that one of the drugs taken to achieve comes with lots of potential mental health side effects - which isn't ideal for a group already prone to depression, etc.
As often happens, I again wondered about the body dysmorphia aspect of trans, which seems such a large part of it. We can all agree that body dysmorphia that leads to anexoria is bad and an issue that needs a mental cure; but when it comes to dysmorphia that is based on gender bits, it's considered wildly improper to approach it in the same way. I looked up links on cognitive behaviour therapy and trans, for example, and as far as I can tell, the only idea about using it is to help trans be happy trans - not to question whether their thoughts about how wrong their body is may be misguided. Yet isn't it used that way to encourage people with healthy bodies to stop thinking there is something wrong with it that will only be cured by being dangerously thin?
I suppose people will say that trans ideation is not only about body dysmorphia - or isn't always. But gee, it's a messy area full of unstated assumptions and ideas that seem to be rarely thought about by those sympathetic to their situation.
I guess it was somewhat refreshing to see a doco that didn't portray the whole issue as if all trans situations would have a happy ending if only everyone would "validate" the person going through it. (He seemed to have lots of support, including from his Mum when he moved back in after the girlfriend left.)

A Carter comparison
My main recollection of how I felt about the Carter presidency at the time is that I thought his popularity suffered because his administration gave the impression of the nation suffering a kind of paralysis in the face of several problems not really within anyone's control. And was there ever a worse Presidential PR look than the one of him running himself into collapse (and being attacked by a rabbit!)
I keep getting the feeling now that the Biden drop in popularity has similar features - OK, so the Congressional paralysis is something he perhaps could have done something about faster, but the other things which Americans are saying concern them (supply chain, the possible return of modest inflation, COVID, border rushes) seem to me to be much harder to pin on Joe.
But that doesn't seem to matter much - Americans like a sense of "moving forward", I reckon, even if the direction is dubious and going to be later regretted. (Like rushing into Middle Eastern wars under Bush.)
You perhaps get similar sentiment in other countries, but the hatred of not moving forward seems something felt particularly keenly in the American public, I suspect.
Some kids brains are really wired differently
I find it impossible to imagine standing that close to the edge, let alone jumping across the gap, from a standing start too!
Sounds like an excellent point
I didn't know that about polio - so I assume most people wouldn't.
I also see on Twitter that the come back to this by COVID anti-vaxxers is "but the COVID vaccine is not a normal vaccine! It's new and untried and you have to keep getting boosters..etc etc".
I've said it before, and say it again: a significant chunk of the Right has spent 20 to 30 years telling each other that there's a massive conspiracy in the scientific community (in the form of climate change.)
Having become so acclimatised to believing one massive conspiracy, they find it easy to swallow another conspiracy that is also actually against their children's interest to believe.

That invisible movie
I watched the 2020 movie The Invisible Man on Netflix on the weekend, and it's very good.
I kept thinking it's a mash up of #MeToo, Marvel-esque "hi tech in the wrong hands", and ghost story (invisible presence in the house). But it worked for me. Most of all, it's the suspense that works well - lots of good directorial decisions as to swapping between point of view and other neat ideas.
It also has a terrific plot surprise that I did not see coming at all. (Ha, I just realised that sounds like a pun on the title, but it wasn't intended as such.)
Now, without ruining my general praise for the movie - I think the ending was bold, and a bit confronting, and perhaps not set up as being as well justified as it could have been. But I still like that the director (who also wrote the movie) and studio went with it. It's the sort of ending it's possible to have decent discussion about afterward.
Anyway, I strongly recommend it.
Not back to normal
I noticed on Insiders yesterday that the journos who had been to Rome and Glasgow with the PM thought that life was looking pretty normal over there (Rome was "pumping" I think Phil Coorey said), and that Australia needed to get used to thinking we have to do the same.
Yet later in the day, I was reading about the surge in COVID cases in Germany, France, and Ireland (all with high vaccination rates), and in a lot of the Eastern European countries (which have low vaccination rates, and seem particularly prone to believing Right wing culture warring on the matter.)
The WHO is worried, and I would guess that what happens with hospitalisation and death rates in the region in the next few months ought to deliver some more important lessons on the value of vaccination.
But it probably won't be simple. This weird pandemic will likely show some countries or regions with patterns that are hard to understand.
Update: As for Italy itself, I just noticed from Nov 6:
Italy has recorded 6,764 COVID cases in the past 24 hours.
Health authorities have confirmed the deaths of 51 people.
Italy’s COVID-related death toll has passed 132,000 – making it the second-highest toll in Europe after the UK.
Update 2: look at the waves of infection in the Netherlands:
And the government has introduced more restrictions due to the current outbreak, leading to this:
Thousands of people paraded through the centre of The Hague on Sunday afternoon to protest at the coronavirus measures currently in place in the Netherlands. New rules, including the return of face masks in shops and wider use of the coronavirus pass system, came into effect on Saturday. Their number included a number of supporters of extreme-right group Voorpost, identified by their use of the the Prinsen flag – an orange, white and blue version of the Dutch flag used by the Dutch Nazi party during World War II. Police estimated the crowd to be at 20,000 to 25,000, website Nu.nl reported. Read more at DutchNews.nl:
Another news article contains this explanation (my bold!) about the new face mask rules:
Face masks Masks will once again be compulsory in all public buildings where coronavirus passes are not required. This includes: Supermarkets and shops Libraries Government buildings and council offices Airports and railway stations Colleges and universities when moving between locations People in contact professions, such as hairdressers, will again have to wear masks, but not sex workers. Those who do not wear a mask can be fined €95. Masks remain compulsory in taxis and on public transport.

How tempting to just advise "get over yourself"...
I have some misgivings about re-publishing this advice column from The Guardian, both because I am not entirely sure it's not a prank, and because if it's not, I don't really want to be part of encouraging other young people to similarly writhe in the somewhat narcissistic world of "what sexuality/gender identity am I today"?
I am 16, and identify as an ace lesbian (NMLNM, or non-men loving non-men). I have questioned my sexuality since the age of 12 or 13, thinking I was bisexual. I downloaded TikTok, which allowed me to explore my identity more and interact with other queer young people. Until this summer, I questioned my identity multiple times a day (exhausting and not affirming), but I slowly began to feel confident in labelling myself as a demi-romantic, asexual lesbian (I like to use labels). However, that feeling didn’t last long. I felt dysphoric a lot of the time, and I hated my breasts. Fortunately, after about a month, I rediscovered the term “demigirl” and it just fitted. I am also trying out she/they pronouns, but haven’t told anyone. My gender is quite fluid – some days I feel more neutral, other days ultrafeminine.
I am open about my sexuality at school and online, and would happily tell most people that I am gay, but don’t want to “come out” to my parents. I think it’s a combination of fear, not of rejection (they are supportive of the LGBTQ+ community), and the fact that I hate the idea of having to “come out” if you are queer; I don’t want to contribute to our heteronormative society. Should I tell my parents so they have time to process it, or should I wait until I have a partner to introduce to them? Also, I feel obliged to inform them of my pronoun change, but I don’t want to be the one to teach them how to use she/they pronouns. I wish they would educate themselves. If I tell them my gender and/or sexuality, I don’t want them to perceive me differently. I know how they react is not in my control, but ideally our relationship will stay the same or improve.
So she both wants to label herself and resents the idea of labelling herself. Makes sense!
Seems to me a good dose of "stop thinking about yourself" might be helpful here.

China follows the ultra conservative path to eliminating homosexuality?
As many have noted in Tweets following, this may be the same as what goes on in Iran (and perhaps some other Muslim countries?):
Old decrepit commentator farewells old decrepit commentator
I've briefly noted before that old-before-his-age conservative commentator Currency Lad, who has resumed blogging, has developed into wordy, muddled, quasi-opaqueness in his writing. I offer an example this piece about the retirement of Alan Jones, which seems to me to swing wildly between praise and condemnation of his "skills", only to finally settle on "he'll be missed". Mind you, I saw on Youtube Andrew Bolt doing his farewell to Jones, and it was somewhat similar. Seems a lot of his defenders have quite a lot of mixed feelings about how he operates.
Let there be no lack of clarity from me - he's a long time disgrace and done more harm to the country than good, by far. I find his personality extremely grating, and have no understanding of how such a bombastic, thinks-he-knows-it-all-but-doesn't style succeeded for so long in media.
