Elon Musk, an immigrant, was interviewed recently by the editor of the Economist. He said a bunch of dumb shit - for example that money wouldn’t exist in 2036, and that everybody wouldn’t have to work any more as AI would do their job for them. Anyway, he’s now essentially calling for the assassination of the journalist over her questions about immigration.

Replying to @mxchara@seattle.pink
@mxchara@seattle.pink There is a huge amount of activity in organic synthesis using different lanthanides salts - especially, but also complexes wrapped with chiral ligands - acting as Lewis acids to catalyze all manner of transformations. Sc(OTf)3 is particularly prized. Not cheap, mind. So it's got to be pretty good if people are going to use it. 😉 And then there's all the low-valent stuff with samarium to drive either radical reactions or Barbier-type processes with added reduction SmI2 is the bomb!

Replying to @mxchara@seattle.pink
@mxchara@seattle.pink There was indeed. And the improved separation of the lanthanides during the Manhattan project was a big driver for the development of ion exchange resins and of solvent extraction, with accompanying developments in ligand chemistry. But Pimentel was really making a comparison with the d-block where you have lots of variable oxidation states, redox chemistry, complex covalency and so on. The lanthanides seemed a bit tame by comparison.

@mxchara@seattle.pink A very smart man who thought that because they all dissolved in acid to give 3+ ions of almost identical size that there was no more to discuss in a textbook. The year was 1975-ish…. The lanthanides continue to surprise us with weird oxidation states and ever more bizarre bonding and magnetism.

It may not be immediately obvious, but it seems pretty shallow to write off a very serious bit of science. Niche, sure. But it sounds a bit like George Pimentel’s legendary dismissal of lanthanide chemistry. There’s plenty of arcane and seemingly dull things (binary and ternary phase diagrams??? Stability constants? LFER?? endless crystal structures??) and then things move on, new tools appear and suddenly they’re the bedrock of a new mash-up. Beware what you dismiss.

The due diligence required to moderate and check our electronic final exam experiment is going to drive me to drink. We now have three versions of every question on the paper (about 80 some shared between 3 papers) and the fiddliness of making sure that each of these versions is the same is going to drive me mad.
And I've discovered that one of my beloved colleagues does not know that when you are generating SMILES strings there's a difference between benzene and cyclohexatriene #teaching

Catching up with a pile of old newspapers, I find @MarcAbrahams@mstdn.science staring out of the 23 April edition of Le Temps. It’s a great paper with smart journalists and little clickbait. IgNobels excepted, of course. 😜
A very good interview with trenchant comment on the threat to US science. And even a passing reference to two banana-clad “badauds” (gawkers/flâneurs).

@H4Heights Yup. But for the US this is dynamite. And it risks upending things, including the auto industry.

To my astonishment it is available on YouTube. Watch it for inspiration as authoritarians come out of the shadows, a reminder of how many around you will compromise with the regime. Watch it because Mussolini's jaw came before Trump. Watch it for the beautiful shots of Módena (stress on the o, please) with its glorious arcades and unforgettable cathedral. Watch it for he savage twists at the end. #resistance #partisans #fascism #women #democracy #cinema /end https://www.youtube.com/watch?v=ctZIy2PNUiI

But the book makes reference to the first film that tried to depict a woman of the resistance, "Libera, Amore mio" (Libera, my love). The heroine is called Libera (“She is free”, played by Claudia Cardinale) a woman who breaks every rules and speaks her mind at every opportunity. Occasionally a bit melodramatic it is a fabulous, almost forgotten film made by Mauro Bolognini in 1975 a date that speaks volumes about how long it for Italian attitudes about women to shift. 2/n

I have been reading “La Resistenza delle Donne” by the writer and journalist Benedetta Tobagi that won the Premio Campiello 2023 (the top literary prize in Italy, first one by Primo Levi). It a gripping account of the role that #women played in the Italian resistance to the Fascist regime. It is grim but extraordinarily uplifting reading. It includes photos of a couple of friends of my grandmother’s who were #partisans. I know little of her activities as she never spoke of it to anyone. 1/n

@PlukkiePanda @Tubemeister@mstdn.social The article points out that price remains lower than what is paid in Europe. As to conversion factors beware US vs Imperial gallons. Step outside the SI system and you’re into a bit of a minefield.

Every so often there is a hilarious detail amid the never ending car-crash that is the Trump “administration”.

“I was at an industry meeting this week, and I can tell you one of the biggest concerns was that we might see diesel prices [in the US] go to $10, and the equipment, you know, the pumps and the dispensers and so forth can’t handle a number that high. That’s incredible,” he said.

From the FT.

@supersciencegrl.co.uk My astonishment with it was - and sorry to be dark here - to the fact that, at Auschwitz, prisoners would be injected with phenol directly into the heart. So the effect of the two isopropyl groups when you inject the stuff knocked me over (groan). And then to my amusement, I discovered that a neighbour of mine did the chemical biology required to identify the binding site on the GABAA receptor. It is an amazing molecule. https://www.nature.com/articles/nchembio.1340

@DrFerrous Yes. The reactions and the species present. One thing I've learned is that asking students to plot titration curves from concentriations and pKa values is quite probing (pace @fclc ). But I also think it's a very valuable learning tool for life scientists to get their heads round.

@AvonVilla I totally endorse your view which is why in my energy work my focus is almost entirely on controls, using kWh rather than any other indicator. People keep saying that we should build a new building to reduce our emissions. they go quiet when I point out that just the steel and concrete of the frame of something to replace our building would contribute 30,000 tonnes in emissions before you even put in the windows and the interiors. I find myself in the minority.

@supersciencegrl.co.uk Thanks. I previously set one about the anaesthetic profolol. I had the idea when the anaesthetist told me that it was diisopropylphenol just as he was injecting it and I didn't even finish the sentence "Oh that give me a great idea for an exam q… " and that was it. The question is still there in our revision bank. LOL

Exam question idea:

“Using the quantities listed on the label calculate the pH of the buffer solution in this enema bottle.”

Thoughts?
