Oh yes we had that on the recent not-really-a-creationist-honest-guv thread: a load of "references without the detail needed to look them up and which, on researching them, seemed not to exist.

That response makes no sense. Are you a human being or a bot? They work in the north. It’s south of Rome where things get iffy. He will be between Genoa and Milan. The job is a thing called Workaway, whereby you do temporary work in exchange for board and lodging and get some free time to experience the place. He has a GCSE in Italian and is fluent in French so getting fluent in Italian in a couple of months should be feasible. His Scottish girlfriend will have a job in Madrid teaching English as a 2nd language and there is talk of him moving on there to pick up Spanish as well. We’ll see. His mother spoke French, English, Dutch, Spanish and Portuguese, so maybe he has inherited her linguistic aptitude. He certainly does not get it from me. His degree is in Ancient History and Archaeology. Dissertation on the cultural significance, trading and manufacture of (so-called) Egyptian faïence in the Eastern Mediterranean, before the Bronze Age Collapse. Quite interesting actually.

Yeah he's taking a year off, starting with a job in Italy, to try to get fluent in Italian, to add to his French and English. He's got an EU passport so maybe he can find something in the EU later on. To prepare, he's working his way through The Hitchhiker's Guide to the Galaxy in Italian, which his girlfriend got for him. Vogone prostetnico Jeltz.

Globe has a flat bottom. But clearly a lousy idea for a paperweight. Haha, I prefer the science explanation. But maybe it's a signal that I need to be more careful. Now that I'm getting old and forgetful, I need to be aware of such things. Regarding my son's graduation, thanks. I was slightly surprised to find that my son's MA hood and gown at St. Andrew's were identical to the one I had at Oxford. I had imagined all these universities would have their own designs. Also the Bachelor one e.g. BSc for the science grads is almost the same too - white rabbit fur lining, though they have a magenta strip that we didn't have. However the PhD gown at St. A is something else: sky blue. Quite striking. (The Oxford D Phil one is blue and red: my friend from uni days, now married to my then girlfriend, looks like an exotic parrot at gaudies.) I chatted to an evangelical vicar and his charming wife from Preston (whom I had sat next to at the ceremony and chatted up). He had been awarded a PhD for a study of the 12 minor prophets of the Old Testament - most of whom I had never heard of, apart from Micah. She had come dressed in sky blue as well. They made a striking couple. I was quite sad to take the train back to London. He's been happy there and very much at home. Now it is all uncertainty and rootlessness again for him. The jobs market in the UK is pretty bad now for graduates, not helped by bloody AI.

Limitless nuclear energy, too cheap to meter.

I've been away for a few days, attending my son's graduation and found a burn mark on the papers on my desk when I returned. I have a paperweight in the form of a transparent glass globe, which I had left holding down some papers because I had the window open in the hot weather before I left. The glass globe had evidently focused the afternoon sun onto the paper and burnt it. It had gone through 3 sheets. I'm damned lucky it didn't set the whole room on fire. Definite learning point there.

Yup, that's a simplified free radical reaction scheme showing the same basic idea as the more complicated ones in the paper.

Good luck then. Good luck, then. So long as you are aware of the pitfalls of AI and use it wisely. 👍

Ahem, yes. Or a sudden 8 para screed full of palaeontological terms about the Cretaceous…..

It has always seemed to me the output of these things reads like a bad undergraduate essay, full of padding and long words to sound impressive. The sort of thing my tutor at uni used to really hate. Interesting to see you and others are starting to quantify the characteristics of their style. On this forum the usual giveaway is a post that suddenly reads like a long piece from a textbook, quite different from the normal style of the person posting it.

But how do you know it is not rubbish? When Large Language Model AI tries to do maths it usually screws up, because it is a language model, not a mathematical model.

There’s a funny story in “American Prometheus” about Feynman, when he was at Los Alamos, discovering a gap under the wire of the security fence and puzzling the guards by repeatedly leaving the compound without apparently ever returning. He was a mischievous fellow.

Exactly. See my later post and the link to the paper. It’s pretty complicated but you can see the sort of thing that goes on.

I found this rather interesting paper which goes into the reactions in Titan’s atmosphere n some detail: https://pubs.acs.org/doi/10.1021/acsearthspacechem.2c00041 It seems one route for acetylene formation involves the methylene radical CH2, in its triplet state, i.e. with 2 unpaired electrons. Two of these can produce acetylene plus hydrogen, apparently. But the chemistry of Titan’s atmosphere is clearly very complex. One key feature is it is a reducing atmosphere, i.e. with no oxygen present. It is this that allows all these hydrocarbon fragments to form and react with one another.

Regarding your ( c ) , if a free radical is formed it will be CH₃• rather than CH₃⁻, and the hydrogen released will be H• rather than H+. The dot denotes an unpaired electron, which makes the species reactive. There is no charge separation so both species are uncharged. CH₃• is known as a methyl radical. A pair of these certainly combine to give ethane, C₂H₆. However the formation of acetylene, HC≡CH, would need further explanation. I could imagine methyl radicals removing H from ethane, perhaps, but 4 would have to be removed before you reached acetylene so this route seems a bit doubtful. Is there a further explanation in Lorentz's book for how acetylene is formed?

Also seems to have been the golden age of teleosts, ammonites, belemnites and, not least, coccoliths, which are responsible for the chalk that gives this period its name. And then there was the takeover of the angiosperms. So perhaps a golden age of life in general.

Good idea. You are now on my Ignore list.

It seems not.

"Quantum" isn't a thing. It is an adjective, or else a noun as in "a quantum" of something. The idea of a singularity at the start of the universe is entirely hypothetical and uncertain. Do not rely on it having been real.

I explained to you almost a year ago that your story is historically completely wrong. Anything the reader "learns" from it will therefore be misinformation. Einstein played no part in any arms race. He did not share information with any military use with both the USA and the USSR. So nobody will use this silly store in any "curriculum", thank God. It is not the dialogue that is silly. It is the false information about Einstein and WW2. If you think it presents "deeper ideas" you are deluding yourself. You have no chance of presenting deeper ideas if you make up rubbish.

Not really. I think love between demanding individuals always involves a certain amount of challenge and proving of one to the other. I think this is healthy and strengthens the bond, even though a certain amount of anxiety is generated in the process. A relationship without challenge would become complacent and dull after a while - and love might fade. (Full disclosure: I was married to an intellectually sharp Parisian woman with definite standards and expectations. She was just what I needed to keep me on my toes.)

Good, at last we are getting some proper information. Thank you. Looking at the first of these, the point it makes appears to be different from what you seem to be suggesting. It is saying that the behaviour of organisms influences how they evolve. I don’t think anyone would have any difficulty with that. There’s an example here: https://www.nhm.ac.uk/our-science/research/projects/behaviour-evolution.html of how bears beginning to hunt fish in the sea led to the evolution of the polar bear as a distinct species. But this is not to suggest that bears decided to adapt themselves to swimming in Arctic waters. The adaptation followed the emerging new behaviour, because utilising this food source improved reproductive success. So this seems to be an example of teleonomy rather than teleology: a fairly important distinction to draw.

The way I read the abstract, it is just announcing a project to test the hypothesis, using antirrhinum (snapdragon), rather than reporting results of a study. But it would be interesting to read the results in due course. Let's hope they avoid too many buzzwords 😁.............

You never did provide that reference to Pigliucci for me, did you? I don't believe you have read any of these references you claim support your notion. You seem to have extraordinary trouble locating them. I share the suspicion of others that many, or perhaps even all, don't even exist. Listing references you have not read is deceit.

Agree apart from your “therefore”. Augustine (of Hippo, writing in about 200AD) just says mankind is destined to resemble God more closely, not that this is because of any current resemblance. What he writes seems consistent with the Christian teaching that Man possesses an immortal soul that can enjoy eternal life with God in heaven. (But I must admit that these early Fathers of the Church wrote in terms of abstract theology that are not always obvious in meaning to those of us who have not studied theology.) The fact that Augustine says this image is that of the Trinity makes clear the image he is talking about is a theological abstraction, rather than a physical resemblance.
