The idea of "European Americans" is also a bit daft (choose one or the other) but that's a different question.

Is Boris Johnson English or American?
He was born in the USA but moved here and got UK citizenship.

Did his appearance suddenly change to match?

His situation is not rare.

Carbon black is cheap and almost indestructible. It will also protect the underlying material from light/ UV.

I'm sorry, but because of a form of APD I cannot decipher words of songs in any of four languages that otherwise I don't have difficulties to understand.

Does this copy of the lyrics help?

When the Tower of Babel fell
It caused a lot of unnecessary Hell.
Personal rapport became a complicated bore
And a lot more difficult than it had been before
when the Tower of Babel fell.

The Chinks and the Japs and the Finns and Lapps
were reduced to a helpless stammer.
And the ancient Greeks took at least six weeks
to learn their Latin grammar.
The guttural wheeze of the Portuguese
filled the brains of the Danes with horror.
And verbs not lust
Caused the final bust
in Sodom and Gomorrah.

If it hadn't been for that bloody building falling flat
I should not have had to learn Italiano
And keep muttering Si, si and Mi chiamano Mimi
Like an aging metropolitan soprano!
I should not have had to look at this ghastly little book
Til my brain becomes as soft as mayonnaise is.
Messrs Hugo and Berlitz
Must have torn themselves to bits
Dreaming up so many useless, useful phrases.

Pray tell me the time
It is six, it is seven
It's half past eleven,
It's twenty to two.
I want thirteen stamps.
Does your child have convulsions?
Please bring me some rhubarb.
I need a shampoo.

How much is this hat?
I desire some red stockings.
My mother is married.
These boots are too small.
My aunt has a cold.
Shall we go to the opera?
This meat is disgusting.
Is this the town hall?

How much is this ribbon?
It's cheap.
It's expensive.
What very fine linen.
What pretty cretonne.
What time is the train?
It is late.
It is early.
It's running on schedule.
It's here.
It has gone.

I've written six letters.
I've written no letters.
Please fetch me a horse.
I have need of a groom.
This isn't my passport.
This isn't my hatbox.
Please show me the way to Napoleon's tomb.

The weather is cooler.
The weather is hotter.
Pray fasten my corset.
Please bring me my cloak.
I've lost my umbrella.
I'm in a great hurry.
I'm going.
I'm staying.
Do you mind if I smoke?

This man is the purser.
This isn't my cabin.
This egg is delicious.
This soup is too thick.
Please bring me a trout.
What an excellent pudding.
Pray hand me my gloves.
I'm going to be sick.

I've heard that one can use a corked wine for cooking, as the cooking allegedly gets rid of the cork taint, but this seems to be disputed.

I can't see a plausible mechanism for getting rid of the trichloroanisole.

It's important to remember that there are two sorts of drinks:

It is not so easy to see how to learn the meaning of words such as 'yesterday' or 'side'.

The great advantage of living in the UK.
You can say "it rained yesterday" to illustrate the meaning of the word, without being confused by the idea that we might have the same weather two days running.
I can, in general, point at the side of something.

I suspect that for any linguistic rule we can come up with, there exists an extant or an extinct language that breaks it.

Is there a rule that says that any long discussion about language ends up full of phrases like this?

OK, pretend I was talking about the bricks.

Red items are red because they reflect red and absorb the shorter-wavelength light (blue) which is higher in energy, and tends to break bonds. Once bonds are broken, the molecule doesn’t have the same reflection and absorption spectrum. So they fade.

Yes and no.
The molecule absorbs energy and some electrons get shuffled round. 
But ordinarily, those electrons manage to transfer their energy to vibrations of the molecule and it's dissipated as heat.
So the molecule isn't usually permanently damaged.
We deliberately chose molecules for their ability to stand up to this process even when it's repeated many times.

Most fading by sunlight is actually caused by UV rather than visible light.

UV photons carry enough energy to break bonds and that's not so easy to recover from.
On the other hand, as has been pointed out, those are clay tiles. The pigment is essentially iron oxide and even if that molecule gets damage, the only plausible products are iron and oxygen. 
If any iron is produced, it wont be long before it rusts back to the original orange/ brown colour.

So it's pretty much permanently light fast.

The discolouration is probably, as SJ says, efflorescence. (I can't absolutely rule out leaching by acid rain or something if the place is in a chemical works or something.)

 

There are two interesting* things;

1 the USA seems to be doing badly, in spite of paying more for healthcare (And it has got worse). Maybe they should change the system.

2 there are differences between various bits  of the population.

I'd be interested to see what other factors are in play.
How does maternal age relate to maternal death rate?
How about number of previous births?
(And come to think of it, how to those relate to infant mortality).

* I'm not saying they are only interesting; they may also be scandalous or frightening, but they are interesting.

The simple answer is buffering.
https://en.wikipedia.org/wiki/Buffer_solution
If you have 5 ppt of citric acid in one wine and 5ppt of citric acid and also 5 ppt of sodium citrate in another wine they will have very different pH values but (relatively) similar tastes.
Or, at least that's what I'm told about the tastes; I never checked.

I don't think this is right, actually. According to the link below, in the UK the tax per bottle is the same for any wine between 5.5 and 15%.

Oops!
Someone changed the rules while I wasn't looking.

An important factor is that stronger wines are more expensive (for tax reasons) and also more harmful to health.

I've read the article https://pingpongacademy.org/ping-pong-vs-table-tennis/ and turned out what's the difference between ping pong and table tennis.

In case anyone wondered, yest this does belong with the jokes.
The Equipment The equipment used in these two sports is another major difference between them. For a start, the pin pong table, about 3.7 mm in diameter, is slightly larger than the table tennis court, which is only 3.4 mm.

I'm just not sure if it's deliberate.

St Petersburg, Russia Lat Long Coordinates Info

I must have been half asleep when I posted that or something.
The longitude- almost exactly 30 degrees- is the one that matters . The time difference should be almost exactly 2 hours.
Today I think the answer is 3 hours, but that 's largely political.

Unless the two fluids you are mixing have the same viscosity to begin with, I don't see how it is possible to have homogenous viscosity without also having homogenous mixing. Whether your program will predict the correct outcome or not is a different matter...

That seems sensible to me.
Even if the materials have the same viscosity to start with, a mixture may have a different viscosity (anyone who has seen an engine where water has got into the oil will know that; the product is much more viscous than the components even though no chemical reaction takes place).

So, if the viscosity is homogeneous, the mixture must also be.

But there's a catch 22 here.
If your model doesn't work, then using a modeled property- like viscosity- won't be a good test.
If you could model the density (which is usually "better behaved"than viscosity) it would be better.

Considering temperature at very high altitudes, affecting density.  How does it work ?

To a very good approximation, the effect of temperature  on the density of air and helium is the same (in percentage terms).
 

The balloon floats because its average density (including the walls of the balloon)is less than that of the air.
As the balloon rises the air gets less dense.
There comes a point where the density of the balloon and the surrounding air are the same and, at that level, it stops rising.

It's made slightly more complicated by the fact that the balloon changes volume (and thus density) as it rises.|
With mylar balloons, once the envelope is "full", the volume stays pretty much constant (until they burst).

High altitude balloons are launched looking rather empty, to allow for expansion as they rise.

Can we make artificial ivory?

Not really.
Ivory is a combination of mineral material (largely hydrated calcium phosphate, I think) and proteins (largely collagen).
Collagen isn't hard to get; nor is the calcium phosphate.
But combining them is impractical/ impossible.

The good news is that the only thing that ever needs ivory is an elephant, and it can make its own.
