We all do what we do best. John is good at this because he obviously loves it. It's ironic that he often protests against such off topic threads and yet spends more space here posting off topic including the threads he starts himself. The reality is he loves this venue mostly because he *can* post off topic.

Off Topic Larkin, OTL. Snarky, rude and often just plain nasty.

How about "accurate"?

Analogies are typically only useful to illustrate a single perspective of a problem. Often people try to extend them too far or to use them in place of the real issue when trying to draw a conclusion. That is a misuse. Because people do this more often than useful application, the statement is accurate.

You appear to be conflating the probability of encountering
a problem with the consequences of encountering that problem.

If there are acceptable mitigations that reduce the probability,
then they are worth taking.

A classic dilemma is what to do with people that increase
the probability that /other/ people will suffer the consequences.
Smoking and passive smoking are a canonical example.
Typhoid Mary is another.

Larkin truly believes the silly stuff he says. It doesn't matter that you explain to him clearly why he is wrong. He chooses to believe something else and will talk all around the facts to prove what he believes.

We can all have biases. But most of us will listen to reason. Some, not so much.

All of those dust motes are >1 micron, or they wouldn't deflect light.
That is at least 30 times the volume of a virus particle.

I doubt he believes that nonsense, he is not illiterate after all.
Looks like he is a party activist, I have never seen anyone not being
such stand behind idiotic claims like the one "viruses too tiny for

Everybody has their blind spots; e.g. notoriously Linus Pauling
and Vitamin C.

Personally I suspect this is such a blind spot, with somebody
thinking that competence in one area translates into competence
in another.

I'm not sure whether his other blind spot (climate change
denial) supports the activist or blind spot hypotheses - or
both :)

If you chose to read - and believe - stuff written by people silly ideas, or written to mislead people into believing something the author finds it advantageous for his readers to believe. mere literacy doesn't provide much protection. You have to read critically, and John Larkin doesn't seem to be able to do that.

> > Looks like he is a party activist, I have never seen anyone not being such stand behind idiotic claims like the one "viruses too tiny for the mask to work".

He doesn't seem to be a party activitist. His friend James Arthur is, and once effectively confessed to having got money from the Koch brothers - indirectly - for being a Tea Party activist, and doing his bit to dismantle the Republican Party.

> Everybody has their blind spots; e.g. notoriously Linus Pauling and Vitamin C.

Animals that can synthesise Vitamin C synthesise quite a lot of it. Pauling thought that meant that having a lot of Vitamin C was a good idea. He did have habit of getting great insights, and not getting them quite right. His helical structure for DNA was almost right.

James Arthur and the Koch brothers both dislike climate change. The Koch brothers would have a much smaller income if people burnt less fossil carbon for fuel.

"Through Americans for Prosperity, the Koch brothers influenced more than 400 members of Congress to sign a pledge to vote against climate change legislation that does not include equivalent tax cuts. In 2010, Koch Industries supported efforts to roll back emission regulations in California."

My recollection from video gaming was that the first third to a half of

If you can breate easily through a cloth mask, or smell smoke, small
stuff will pass through the weave. Vocal chords are great atomizers of
watery droplets loaded with viruses. The water evaporates and clumps
of residual stuff, loaded with multiple viruses, become essentially
floating dust particles that are in no hurry to drop onto nearby
surfaces.

https://www.cambridge.org/core/journals/journal-of-fluid-mechanics/article/flow-physics-of-covid19/476E32549012B3620D2452F30F2567F1

(sort of a summary of how much we don't know)

It occurrs to me that if one expels a large droplet, and it is trapped
in a cloth mask, and it evaporates there, and the mask is flexed as
one later exhales, the residual is expelled from the fabric as tiny
motes. So a mask can convert big, short-range droplets into many more
small, long-range particles with high virus concentrations.

After all, if a mask traps viruses, it fills up with viruses. Yuk.

It wouldn't surprise me if that happened to some extent.
The important questions are:
- to what extent
- is it better or worse with the mask; nothing is perfect

> After all, if a mask traps viruses, it fills up with viruses. Yuk.

Yes, and then the question is how long they remain viable.

If you are working in a "high virus density" environment
(e.g. a hospital), then you should take far more precautions
than elsewhere. Certainly doctors etc are taught how to take
PPE on and off; there's a video of it somewhere on yootube,
and it is quite understandable and a hell of a palava.

Since I avoid high risk areas as far as possible, I take
very few precautions about how I use a mask.

Smelling smoke depends on detecting individual molecules - which are lot smaller than the water droplets that carry Covid-19 molecules around, and are lot less likely to stick to the hydrophilic surfaces in a woven cloth mask.

Not all the water evaporates by any means - the biological stuff does retain a lot of it, and the clumps remain a lot stickier than regular dust.

Why should they be expelled from the fabric? You'd expect them to stick to it and get buried in the gaps between the individual fibres.

There aren't that many viral particles around, and they aren't large. John Larkin can't do quantitative thinking.

It's shocking to me, after all this time, how much we don't know. The
sorts of experiments that people used to do are now "unethical."

Seems that letting millions of people die, and destroying millions of
businesses, is kinda unethical too.

If water has evaporated, the virus particle is soon to become nonviable.
The virus is not a spore, not hardened to survive long times out of aqueous medium.
Floors have been found to have lots of virus particles, so 'no hurry to drop'
might apply, but that's a statistical question.

The virus could as well 'float' into and out of your lungs without being
trapped there, but that's not the high-probability scenario.

That's why mask disposal or laundry is another part of the solution.
Filling your lungs with virus is not part of the solution.
While wearing a mask, your moist breath might inhibit the 'drying out'
of trapped material. The mask material by itself does not
spontaneously expel particles into the air. If such particles are
released, half the time it's on your inhalation... no big deal if you're
already infected.

Being shocked isn't productive, so do some experiment design instead.
Experiments can be without people or with non-infective materials,
and can be challenged as uninformative, so it's rarely easy to be certain
of the results' significance. Unethical means you're thinking of something
naughty, doesn't it? And you intend to publish that work?

> Seems that letting millions of people die, and destroying millions of

Persons are mortal, 'letting' them die is inevitable, unless you refer to
assault with that odd language?

"Destroying businesses" sounds bad, but it just means reallocation of capital
and human resources, i.e. means a normal business decision. Happens every
Tuesday, after lunch. A pandemic event disturbs 'business as usual', and always
will, so if you want to save 'business as usual', strengthen WHO and CDC and other
protections against disease, like Trump did not.

Cloth masks are not N95 and are not actually rated at all since they do not work as well.

"Droplets larger than a critical size settle faster than they evaporate, and so contaminate surrounding surfaces. Droplets smaller than this size evaporate faster than they settle, so forming droplet nuclei that can stay airborne for hours and may be transported over long distances."

Yeah, so some smaller particles float and larger ones don't. That says nothing about what gets past a mask. Bottom line is N95 are the best tool in our arsenal to fighting this pandemic. There are no guarantees. I think many people who resist wearing masks are expressing their anxiety about the disease. It is easier to reject the need for fighting the pandemic than it is to try to take actions you don't understand. I feel this myself as I understand many of the limitations of our efforts. Much of the inconsistency is from trying to create regulations that match well against reality. I get that and obey the rules that are mostly window dressing because if nothing else it makes people feel better while resisting any of the regulations just makes more people doubt the whole effort. The most important thing now is to have regulations that include effective measures and get people to follow them.

Here in Puerto Rico they measure temperature and use hand cleaner when entering any business, no matter how small and of course everyone wears masks. Many places have a worker to enforce this and people simply have no problem with any of it. As a result the numbers are very low here.. but, like much of the US, they are starting to ramp back up.

There's no reason to think significant numbers of these dry particles will be expelled while breathing. Once microscopic objects come in contact very strong atomic forces hold them together. These forces are not strong compared to covalent bonds, but compared to the mass and acceleration forces they feel, these forces are enough to prevent them from parting. Also, the droplets have wetted the fibers of the mask and the solute have been dispersed, so their are no "particles" to be ejected.

> After all, if a mask traps viruses, it fills up with viruses. Yuk.

That's why they are disposable.

I wish once in a while you would do your own thinking rather than asking others to think for you.

Which is why you treat them as "single use" products.

How often did you reuse condoms?

I put my mask on just before entering a store (public place).
I keep it on until I return to my vehicle. I sanitize my
hands (cuz I've "touched stuff" along the way). Then, remove
the mask by grabbing the paracord straps that encircle my
head (i.e., NOT the fabric of the mask). Then, sanitize my
hands, again.

In 18 months, the two of us have just finished our second
liter bottle of sanitizer. So, it's obviously not been a
significant factor in our lives!

UK has been doing challenge tests on fit young volunteers but the
results are less than satisfactory since the predominant strain now has
something like 5x the infectious power of the Wuhan one that they
studied. Trying to hit a moving target is difficult. The Wuhan strain is
all but extinct in the wild now so their data will not be that relevant.

I would still like to see it published though.

You can only control the number of deaths from Covid by employing
counter measures to minimise its spread. Most of those will have impacts
on businesses - although not as great in some as in others.

Locking down hard and fast seems to work much better than allowing it to
run out of control until you are within a week of health system overload
and then locking down. Not that the UK seems able to learn that lesson.

Tourism, air travel and the hospitality industry are toast at the
moment. UK has a green list of countries you can fly to but those
countries would be absolute fools to let delta Covid infected Brits in.

Some businesses may well go to the wall. UK government has been
relatively good at supporting businesses through the pandemic but
running up a very large debt in the process. Unlocking too soon and in a
cavalier manner (which is exactly what we are about to do) will almost
certainly result in yet another lockdown in this "irreversible" process.

The trouble with electing a populist narcissistic demagogue to power is
that you get crazy decisions made by your national government. The Boris
is pretty much Trump lite with a smattering of pig Latin thrown in.

Lol! I'm not sure what you mean by a smattering of pig Latin, but it made me literally laugh out loud. Does Boris talk funny in some way? Or is this just to say that he talks a lot of nonsense?

Inserting random Latin phrases into oratory to sound erudite. He was
educated at Eton then Oxford and behaves like a self entitled toff.

Here is a sample from weekly satirical radio show "Dead Ringers" 1m30 in
(you might also like the following sketch). You may need to spoof a UK
IP address to gain access to the BBC site Sounds.

I was able to play the track, but unfortunately I don't speak the language, so I couldn't make much sense of it.

I liked the sketches, pretty good. Did not comprehend only "Harry Kane",
though I do understand him in real life interviews :). Wayne Rooney was
harder, Alex Ferguson and Kenny Dalglish - well, I have sincerely
wondered at times whether they can understand each other... I only
manage to capture every other word or so.
(The audio was available to a Bulgarian IP address, too, so I guess it
is not restricted, unlike say "match of the day").
Liked particularly the part when the labour leader talked about the
skill it takes to lose... Was pretty good.
Boris sounded quite authentic to my ear (Kane did not), Trump was pretty
close, too.
At the moment I think I hear Anne Robinson ("The Weakest Link" was on
BBC World for years here), not bad either.
