Today I Learned
Today I was the “cantor” at Sunday mass for the Ave Regina Caelorum…..and learned we can call on a new guest soprano to help out from time to time, a pretty young woman by the name of Liberty, with a lovely (and clearly trained) voice. I had no idea this could be a girl’s name. I rather like it - and her - I must say.

Everything is Foreign Relations to Trump
I share your fears. I am no longer confident the Supreme Court (or should that be Chicken?) is effective any longer. They have been due for weeks now to issue their judgement on whether or not Trump's tariffs are constitutional. I think they know damned well they are not, but are afraid to issue the judgement because of the damage that would do to Trump and his administration, both internationally and domestically (unwinding illegal tariffs would involve compensating the affected importers). In any case, the enforcing of court orders requires in the last resort the use of the US Marshals........which is an agency reporting to a certain Pam Bondi. So good luck with that, if and when a showdown with the courts arises. It also looks as if the role of ICE is gradually being expanded beyond its original remit of rounding up illegal immigrants. I note in particular the alarming presence of ICE to provide protection to Vance during his attendance at the Winter Olympics, in Italy. WTF? They seem to be morphing into a new arm of state security, outside the systems, controls - and training - of the normal security services and answerable to no one. They have already established a reputation for killing citizens with impunity. So the fear factor is being ramped up. What next? Brown shirts and diagonal leather straps across the chests?

Madhouse Politics and Green Energy - Solutions please.
I have never understood how this can work at scale. It seems to me the mass of such weights cannot remotely compare with the mass of water that can be given extra gravitational potential energy by a couple of reversible pump/turbines in the space of a few hours. I think, though, I would expect the losses to be lower than with pumped storage, as there won't be losses to turbulence and "slippage" through the turbine. It will be just a matter of the efficiency of the electric motor/generator running in forward and reverse directions, which you also have in a pumped storage setup.

1960s special effects were pretty primitive.

How should we use AI in medicine ?
Indeed. I don't know how diagnostic AI works but I imagine it may look for patterns in the data: X-ray pictures, blood analyses, physical examinations and so forth, and then provide the doctor with an assessment of probabilities of different conditions, or something like that. In this sad case, I imagine the doctor would then have had to make a decision to dismiss cancer from the list of possible conditions presented to him or her in black and white. This would be psychologically hard to do - and to justify in retrospect - if the AI came up with a probability of, say, over 20% for cancer. So maybe it might have prompted an intervention.

Hmm, I think this may be misunderstanding how diagnostic AI works. These are, to my understanding, not LLMs.

Mechanism of hidden authoritarianism in Western countries
Merkel took that decision in 2011, in the wake of the Fukushima accident and long before Putin's invasion of Crimea. At the time, Germany had not yet given up Russia becoming a civilised trading partner. It is true that, even at the time, many other countries thought it a misguided over-reaction, given the climate change imperative (not to mention the absence of earthquake risk in Germany!). But there is no evidence of any "payment" to make this decision, so far as I am aware. This looks to me like just more of your (very Russian, trollish) obsession with conspiracies.

What are you listening to right now?
Presumably because GDAE is how a violin is tuned, I seem to recall from when one of my brothers used to play.

Oh so you actually went to see it? We didn't. We just laughed at the posters for it on the Underground, on our way to and from school.

Haha I remember that one: "Krakatoa, East of Java". 🤪 I was at school at the time and we laughed at the idiocy.

That’s interesting. Seems the story of him being on death row is untrue. Also I was wrong about the number who died: 30,000 not 20, 000. Lacroix, who was among the first on the scene, took dramatic pictures of the aftermath which Holmes reproduced in the book, including the sinister “spine”, turdlike, of almost solid lava, which was extruded up to a height of I think ~ 100m afterwards, though it soon crumbled. It even glowed in the dark, creepily, for a bit, I think. You can visit Sylbaris’s cell among the ruins. I found Martinique, being part of France, orderly and good to visit. I tried my first ti’ punch there - something I often make at home now in the summer. Needs rhum agricole, which I buy in France - Bacardi no good at all for it. We also tried sugar cane juice, on the beach. Very good and with far more flavour than I was expecting. (But you will know all this, being in the Caribbean yourself.🙂)

Holmes also contained a dramatic account of the 1902 eruption of la montagne Pelée which destroyed st. Pierre in Martinique, which made a great impression on me. At that time, the term he used for what we now call a pyroclastic flow was une nuée ardente. I think it may have originated with that eruption. Some years ago I climbed the mountain with my wife and son, as far as the 1st crater rim. Bizarrely, she was rung up by her uncle in Paris, just as we reached the ridge. He had no idea where we were. The ruins of St. Pierre are a sombre reminder of the tragedy. 20,000 people perished. I think only three survived, one of them, ironically, a condemned convict in a deep cell in the prison, who subsequently earned a living by showing off the scars on his back from the burns. They never had the heart to rebuild, establishing a new capital at Fort de France.

Yes! That was why my mother, then teaching geography at the local girls' grammar school, bought the book. Plate tectonics was the new thing. She was quite excited by it and so, having a scientifically-minded boy's interest in volcanoes, I read parts of the book myself. Of course the detailed understanding of how volcanoes arise behind subduction zones has progressed hugely since then, but the principle was already there.

I remember reading an account of this in Arthur Holmes's Principles of Physical Geology, as a teenager in the 1960s. At that time Anak Krakatau was quite small, still. Now, I gather, it has grown to adulthood and has even suffered a collapse rather like that of its parent, though not as dramatic.

[Chem-Applied] Vapour pressure of Pure Liquids A & B are 450 & 700mmHg respect. @350 K . Find comp. of liquid mix, total Vapour pressure is 600mmHg and Vapour phase composition
The question tells you A and B are pure liquids, not mixtures. Why are you asking about the composition of liquid A, then?
