And now for something completely different.
The Borgias are having an orgy

Posted in The Universe and Stuff with tags anomalous magnetic moment, arXiv:2505.21476, muon, muon magnetic moment, Particle Physics on June 10, 2025 by telescoperA couple of years ago I posted an item about a measurement of the anomalous magnetic moment of the muon, a quantity usually known as (g-2). At the time this appeared to be in conflict with the predictions of the standard model (SM)of particle physics but the general opinion among experts was that the problem was likely to lie with the calculations rather than the experiment.
Well, catching up on things I missed during examination marking season, I refer you to a substantial paper (188 pages long) that appeared on arXiv on 27th May 2025, with the abstract:
If this is too small to read I direct yourself to the salient point, namely that “there is no tension between the SM and experiment at the current level of precision”.
It seems the Standard Model survives to fight another day…
On Scholarly Communication
Posted in Open Access with tags Academic Journal Racket, European University Association, Open Access Publishing, Research Assessment, Scholarly Communication on June 9, 2025 by telescoperMy marking duties being over, it’s time once more to take up the cudgels against the academic publishing racket, at least in a small way, by sharing an article from the European University Association called Reclaiming academic ownership of the scholarly communication system. I recommend you read the entire piece, which is an extended briefing note. It can be downloaded as a PDF here. One of the points it makes very strongly is how much the Open Access movement has been hijacked by commercial publishers.
I will share a couple of sections with you here. First, some background information about Open Access Publishing:

Now I’ll cut to the chase and share the key points from the end.
- Accelerate the reform of research assessment. Most of the issues in the current publishing system are rooted in how academic staff are evaluated. Research assessment reform is essential to break the cycle of dependence on high-impact commercial journals and related metrics. Universities should consider broadening the criteria used in academic evaluation, to ensure that recognition goes beyond research to include teaching, innovation, leadership, open science practices, and societal outreach. While institutional, regulatory, and cultural factors can either facilitate or hinder reforms, many universities are already taking the initiative and implementing changes (even in countries with centrally regulated academic career assessment processes).
- Strengthen institutional publishing services and infrastructures. A robust, sustainable and interoperable scholarly publishing ecosystem requires each university to properly curate their research contributions and outputs, through institutional or shared infrastructure and services (e.g. repositories, publishing platforms, and CRIS systems). Strengthening these institutional capacities may require reallocating resources and cooperation (see points 3 and 4). This should also apply to the various institutional departments (libraries, research management, etc.) and staff needed to support academics and researchers.
- Cooperate and coordinate with other universities, research performing and funding organisations, as well as researchers’ associations and learned societies. The challenges of scholarly publishing are systemic, and no single institution can tackle them alone. Universities should align their efforts with other academic organisations, funders and research institutions. Cooperation and coordination can be valuable for advocacy, policy development and implementation, as well as for shared or “horizontal” services and infrastructures. Cooperation can also take place within regional, national, European and global frameworks.
- Critically evaluate expenditure on commercial research publishing and information products and services. As new not-for-profit publishing alternatives emerge and consolidate, universities should regularly evaluate their expenditure on commercial products and services, including journal publication costs and research databases. By promoting cost transparency and cost efficiency, institutions can make informed decisions that support innovation and reinvest funds into institutional publishing services and infrastructure (see point 2). Where feasible, preference should be given to not-for-profit solutions, ultimately reducing costs and ensuring sustainability.
- Support and promote the use of rights retention by the university community. Rights retention should be used to regain academic ownership of scholarly communication. Universities should actively advocate for legislative reforms that allow researchers to retain their rights and freely share their research. They should also educate and inform their faculty and researchers of the importance of rights retention and provide legal support. Where legally feasible, institutions should implement and enforce rights retention policies to ensure that publicly funded research remains publicly accessible.
- Ensure researcher engagement. Any transition toward a more equitable and sustainable scholarly communication system must involve the academic community. Universities should raise awareness of the systemic issues in scholarly publishing and create spaces for dialogue, reflection, and co-design to discuss how to address them at institutional level. Engaging researchers early and consistently can help shift perceptions, foster a sense of shared responsibility and build support for longterm cultural change.
I endorse all of these, and have written about some of them before (e.g. here) but I would add to the first that universities should actively lobby their governments to change research assessment methods which in many cases are causing an immense waste of public money by outsourcing research assessment to entities, such as Scopus, who are mere fronts for the academic publishing industry.
Marking Over
Posted in Biographical, Education, Maynooth with tags Computational Physics, Examinations on June 9, 2025 by telescoperBetter is the end of a thing than the beginning thereof…
I’ve just graded the last of my assignments for this (academic year). I had a bigger class than usual for Computational Physics this time round, so it took much longer than usual to mark the project component. It always takes a while because I not only have to read and grade the reports, but also look at the code they submit and run it to check that it works. I uploaded the final grades to our system just now and although I finished later than planned I was relieved to see that I’m not the last lecturer to do so!
What happens next is that all the marks from all the modules will be collated and cross-checked. Then we will have a meeting of the Departmental Examination Board (on Thursday morning) to go through the results in the presence of our External Examiner. Since this is the end of the academic year, we will also look at the final grades of those students who are completing their studies this year in order to consider the classification of their degrees. There may also be some who are not qualified to graduate and may have to repeat failed examinations or other assessments. Another (pleasant) duty of our Examination Board on Thursday will be to award prizes for the best performance, not just for finalists but for students at every stage, including the first year.
I was teaching a module for the Department of Engineering last Semester so I should attend their final Examination Board too. Many of our students at Maynooth take joint degrees, in which case their final degree classification depends on grades from two Departments. For that reason, there is an overall Examination Board at which the marks are combined. Fortunately, only the Head of Department (who is not me) has to attend that one.
If all goes to plan, students will receive their final marks on Friday 27th June. It’s a lengthy process so as to allow plenty of opportunities to check and validate the different stages. After that, on Tuesday 1st July, we have a consultation day at which students can ask for advice about repeat examinations, etc, and after that we have to make sure repeat examinations are available. The repeat examination period is Wednesday 6th August to Tuesday 19th August.
Between the end of this week and the repeat exams, perhaps I’ll get a bit of time to do some research…
The Cosmic Poltergeist
Posted in Film, The Universe and Stuff with tags Cosmic Microwave Background, Cosmology, Poltergeist on June 8, 2025 by telescoperLast night I stayed up long past my usual bedtime to watch the film Poltergeist. This film, about the haunting of a family house by malevolent spirits, was a huge hit when it came out in cinemas back 1982, and I was interested to see how well it has endured. I think it stans up pretty well actually. The special effects could be done better nowadays, but it is still credibly scary.

The idea of a poltergeist is not new, but the film cleverly combines the old legends with new technology, in the way that the first manifestation of an evil presence is through a TV set. It is the youngest child of the house in question, Carol Anne, who is able to detect the ghosts when all we can see on the screen is static. The implication is that the young are the most receptive to paranormal phenomena.

Most of the static produced in a TV set when it is not tuned to a broadcast frequency is produced by thermal noise in the receiver, but around 1% of it comes from the cosmic microwave background (CMB). I’ve used static on a TV screen as a gimmick in public lectures on several occasions, with the joke that it may only be 1% but the birth of the Universe is far more interesting than most things you can see on TV!
The CMB is a ghost of the Big Bang. Watching Poltergeist last night, it occurred to me that when cosmologists study this relic radiation, we are all a bit like Carol Anne, trying to make sense of an eery presence that is always with us, but is barely perceptible. Such studies involve extensive use of spectral analysis.
This line of thinking led me to my new theory of the Universe. Perhaps it was built on the remains of an earlier, deceased Universe which is now trying to make contact this one in order to wreak revenge for the violation of its grave…
The 2025 Leaving Certificate Mathematics Papers
Posted in Education, mathematics with tags Higher Mathematics, Leaving Certificate, mathematics on June 7, 2025 by telescoperAs I mentioned a few days ago, examinations for the 2025 school Leaving Certificate are under way. One of the interesting things about the Irish system is that the examination papers are put up online immediately after the examinations. Students took their first paper in Mathematics (either Ordinary or Higher level) on Friday (yesterday), and there has been some reaction.
Anyway, I thought I’d share the papers here so you can see what you think. Paper 2 is on Monday 9th June, so I’ll add those papers then.
They look reasonable to me. The thing that strikes me about them is that they are much more structured than the A-level mathematics examinations I took way back in 1981.
Comments are welcome through the box below.
Update: As promised here are the Papers 2:
Reaction to Paper 2 of Higher Mathematics is that it was more challenging than Paper 1.
Weekly Update from the Open Journal of Astrophysics – 07/06/2025
Posted in OJAp Papers, Open Access, The Universe and Stuff with tags arXiv:2410.17312v2, arXiv:2503.18617v2, Astrophysics of Galaxies, Diamond Open Acccess, Instrumentation and Methods for Astrophysics, Milky Way, neural networks, Open Journal of Astrophysics, spectroscopy, stellar spectra, Stellar streams, The Open Journal of Astrophysics on June 7, 2025 by telescoperIt’s Saturday so once again it’s time for the weekly update of papers published at the Open Journal of Astrophysics. Since the last update we have published two new papers, which brings the number in Volume 8 (2025) up to 69 and the total so far published by OJAp is now up to 304.
The two papers published this week, with their overlays, are as follows. You can click on the images of the overlays to make them larger should you wish to do so.
The first paper to report is “Chemical Abundances in the Leiptr Stellar Stream: A Disrupted Ultra-faint Dwarf Galaxy?” by Kaia R. Atzberger (Ohio State University) and 13 others based in the USA, Germany, the UK, Sweden, Australia, Canada and Brazil. This one was published on 2nd June 2025 and is in the folder marked Astrophysics of Galaxies. It presents a spectroscopic study of stars in a stellar stream suggesting that the stream originated by the accretion of a dwarf galaxy by the Milky Way.
The overlay is here:
You can read the final accepted version on arXiv here.
The second paper is “Scaling Laws for Emulation of Stellar Spectra” by Tomasz Różański (Australian Nastional University) and Yuan-Sen Ting (Ohio State University, USA). This was published yesterday, i.e. on 6th June 2025, and is in the folder Instrumentation and Methods for Astrophysics. The paper discusses certain scaling models and their use to achieve optimal performance for neural network emulators in the inference of stellar parameters and element abundances from spectroscopic data.
The overlay is here:
You can find the officially-accepted version of the paper on arXiv here.
That’s the papers for this week. I’ll post another update next weekend.
As a postscript I have a small announcement about our social media. Owing to the imminent demise of Astrodon, we have moved the Mastodon profile of the Open Journal of Astrophysics to a new instance, Fediscience. You can find us here. The old profile currently redirects to the new one, but you might want to update your links as the old server will eventually go offline.
R.I.P. Edmund White (1940-2025)
Posted in Biographical, LGBTQ+, Literature, R.I.P. with tags A Boy's Own Story, Edmund White on June 6, 2025 by telescoperI was saddened to hear of the death on Tuesday at the age of 85 of novelist Edmund White. Like many gay men of my age I read his semi-autobiographical novel A Boy’s Own Story as a teenager, and it had a profound effect on me.
It’s the story of an adolescent boy coming to terms with his sexuality in the American mid-West during the 1950s. It is as frank about the description of gay sex as it is truthful about the confusion that goes with being a teenager. When I bought it I didn’t realize it was going to be so sexually explicit, as the whole subject of gay sex was very much taboo in those days. I didn’t think it was possible to write about such things in such a matter-of-fact way and at the same time so beautifully. The book is also unflinching in its description of the personality flaws of the central character.
The Irish Times has a collection of reflections by various writers on Edmund White that say far more, and far more eloquently, than I ever could. I’ll just say, as a (now) sixty-something gay man that Edmund White helped me on my journey to self-acceptance when I was a struggling teenager all those years ago, and for that I will always be profoundly grateful.
Rest in peace, Edmund White (1940-2025).
L’elisir d’amore at the National Opera House
Posted in Opera with tags Claudia Boyle, Duke Kim, Erina Yashima, Gaetano Donizetti, Irish National Opera, John Molloy, Le'lisir d'amore, National Opera House, Opera on June 5, 2025 by telescoperMy trip to Wexford was to mark a special occasion by paying my first ever visit to the National Opera House to see a performance of Donizetti’s comic opera L’elisir d’amore by Irish National Opera. It was well worth the trip, as it was a wonderfully entertaining production with lovely singing and lots of laugh-out-loud moments. In short, it was a blast.
Billed as a melodramma giocoso, but more usually called an opera buffa, this was the first Donizetti opera to be performed in Ireland, in 1838; its world premiere was in 1832 in Milan and it has been in the operatic repertoire ever since. The show-stopping Una furtiva lagrima in Act II is one of the most recorded tenor arias, the first recording of which dates back to 1904 (by Enrico Caruso).
In case you’re not aware of the opera, it tells the story of a lowly peasant (Nemorino, tenor) who is in love with the wealthy Adina (soprano), who does not return his love – understandably not just because he’s poor but because he’s a bit of a drip. In despair Nemorino turns to the fake doctor Dulcamara (bass-baritone) “famous throughout the Universe and certain other places” who has arrived in town to peddle potions and quack remedies, no doubt made from snake oil. Nemorino asks him for a philtre that will make Adina fall for him. Dulcamara has sold all his potions, but fills an empty medicine bottle with wine and tells him it’s the love potion he needs. After drinking it, Nemorino feels more confident, but Adina still isn’t interested. Worse, Adina has agreed to marry to soldier Belcore. That’s Act I.
In Act II, desperate to stop the marriage, Nemorino wants to buy some more of the love potion but he has no money so he agrees to join the army for which he is entitled to a joining fee. He spends the money on more wine and gets completely wasted, so much so that he misses the news that a rich uncle has died and left him a large inheritance. When the women of the town find out that he is now rich, they all start showing an interest in Nemorino, which he assumes is because of the love-potion. At this point Adina decides she really does love Nemorino, buys out his contract with the army, and calls off the wedding with Belcore. The soldier shrugs off his loss. Dulcamara convinces himself that he really has magical powers…
Summarizing the plot doesn’t really do justice to the opera, however, as there are numerous musical interludes, with dancing, and slapstick comedy. Donizetti’s music is wonderful, and keeps the pace going. It’s basically a theatrical farce set to music, with the score keeping everything moving at the speed that is essential to make such a thing work. Erina Tashima conducted the Orchestra of Irish National Opera with great verve.
This production is set in a comical Wild West of America, with a relatively simple set but wonderful very witty costumes. Nemorino (Duke Kim) was dressed like Woody from Toy Story, for example. We also had appearances from Calamity Jane, Laurely & Hardy (who do their “Way Out West” dance), Abraham Lincoln and even the couple from Grant Wood’s painting American Gothic. Adina (Claudia Boyle) has no fewer than five costume changes, each one into a frock more glamorous than the previous. Dulcamara was the wonderful John Molloy and there is great comedy between him and his diminutive sidekick Truffaldino (a non-singing part played by Ian O’Reilly). Belcore’s troops are kitted out like the US Cavalry, and their dancing and messing about delivers laugh after laugh. There are also sundry “peasants”, i.e. cowboys and women of the town adding to the hilarity. I give 10/10 to the members of the chorus, their Director Richard McGrath and choreographer Paula O’Reilly.
All the principles were great too. Claudia Boyle sang beautifully, but also conveyed the comic aspects of her role. Duke Kim was perfectly cast as the boyish Nemorino; he has a light and agile tenor voice, which he used to bring the house down with the big number Una Furtiva Lagrima in Act II. Belcore was baritone Gianluca Margheri (whom I saw perform in Maynooth a couple of years ago). His physique matches the muscular quality of his voice, and he wasn’t shy in showing it off by taking off his shirt onstage! John Molloy’s singing was as impeccable as his comic timing in the role of Dulcamara. I think he got the most laughs, in a production that produced many.
This triumphant production plays L’elisir d’amore for laughs and wins by a knockout. Sadly there’s only one performance left in this run, in Cork on Saturday 7th June. Do go if you can!
To Wexford and Back
Posted in Biographical with tags Curracloe Beach, Iarnród Éireann, Irish Rail, Wexford on June 5, 2025 by telescoper
I’m currently on the train travelling back from Wexford to Dublin. The WIFI is a bit flaky so I’ll post more about the reasons for this trip later on, when I get home.
For the moment, I’ll just say that Wexford (Irish name: Loch Garman) is a picturesque historic town at the mouth of the River Slaney, near the Southeastern corner of Ireland. I had a nice walk around this morning. It’s a pleasant place to stroll about; the streets still follow an obviously mediaeval layout, and parts of the old city wall are still standing.
The train journey from Dublin is very enjoyable, right along the coast for a while, then heading inland, then along the banks of the Slaney. The train isn’t very fast, but it is comfortable and costs less than €10 each way. There’s only a single line from Wicklow to Wexford, which severely limits the number of trains that can operate on the route. The same is true of the Maynooth-Sligo service, actually.
When I moved to Ireland (about 7 1/2 years ago), I planned to travel around and see some of the historic places. Workload issues and the pandemic put paid to that idea for a while, but I have a bit more time to travel now.
P.S. Curracloe Beach, a few miles North of Wexford, stood in for Omaha Beach for the film Saving Private Ryan. I didn’t have time to go there.
