The fact that it had been raining very heavily for days before the storm must have saturated the ground, which would have contributed to the flooding. Unusually, the worst of the flood has been on the East Coast, with Counties Wexford, Wicklow, Carlow, and Dublin badly hit. Usually it’s the West of Ireland that bears the brunt of storms which usually come from across the Atlantic.
It’s been a strange day in Maynooth because, despite the storm, the weather hasn’t been too bad at all. There was a long window this morning during which it was actually quite sunny and pleasantly mild, though a bit breezy. The picture on the left shows the situation in mid-morning when the prevailing wind was southerly.
The main mass of raincloud to the North had passed over us by then, and the small but intense strip off the Louth/Dublin coast missed Maynooth entirely. You can see a big gap. Rain was heading towards us from the South, and did reach us in the afternoon, though it wasn’t particularly severe. It remained reasonably warm throughout the day, though it is much colder now (I’m writing this at about 7.30pm).
Dublin is only about 25km from Maynooth and it was a surprise to see major flooding, with parts of the M50 flooded for a time while we experienced nothing particularly severe. Not that I’m complaining!

Well, that wasn’t too painful. I’ve completed my marking duties. The fact that it has been pouring with rain most of the day made it easy to concentrate on this task. I was going to have a break for lunch, but I decided to keep on going until I was finished, though I did have to take a break for a telecon this afternoon. I also had to dash out to the shops, primarily to replenish my stock of food for the garden birds but also to get some groceries for myself. Having skipped lunch I bought myself something nice for supper.
Looking at the departmental database I see that I appear to be the first member of staff to have finished and uploaded all their Semester 1 examination marking. Normally I’m just happy if I’m not the last!
It feels good to have finished this task. It’s definitely a weight off my mind. I wouldn’t want to leave any loose ends when Trumpageddon comes.
I can’t say anything about the results of course but the change I made to continuous assessment, from take-home assignments to class tests, does not seem to have had a negative effect on either group of students I have been teaching. The opposite may indeed have been the case, as the class tests perhaps provide better preparation for the final assessment than the previous method. I think some other lecturers might make a similar switch in future. Anyway, I definitely plan to do something similar for my Semester 2 module on Particle Physics.
Now I have a couple of weeks before teaching resumes so I can get on with other things. For the rest of this week my priority is to finish revising a paper that I hoped to do before Christmas. I’ll see how that goes before deciding what to do next.
I’ll also have to prepare teaching for Semester 2. That shouldn’t be too difficult, as I’ve taught both modules before, but I do have to give some thought as to precisely how I’m going to word the instructions on the use of AI for my Computational Physics module. That can wait a little while, though, as it mainly affects the mini-project to be done towards the end of the Semester. In the meantime I’ll be thinking about other things…
Last year, we made the decision to step away from X.
The Royal Irish Academy is committed to creating, convening, and sharing knowledge for the public good and as an organisation we value Independence; Integrity; Curiosity; Openness and Rigour.
In our view, X no longer aligns with these values
This is a correct decision by the RIA, and although I’m no longer a Fellow of either the Royal Astronomical Society or the Institute of Physics, I am glad they came to the same conclusion. On the other hand, the Royal Society (of which the Royal Irish Academy is the Irish equivalent) continues to endorse X and its machineries of abuse; this is unsurprising because Elon Musk, who owns X and actively promotes the generation of images of child sexual abuse, is a member of that particular club.
All academic institutions should close their accounts on X. There is no acceptable justification to contribute to a network that promotes racism, transphobia, misogyny and the manufacture and distribution of child pornography. I would have thought this was obvious, but it seems not to be. My employer, Maynooth University, has not yet made any statement about the situation with X, and continues to post there.
As I wrote in a recent post
If you don’t leave a social media platform when you find out that it endorses and encourages abusive exploitation of children then you are supporting that behaviour and helping to promote it. There is no grey area here in this. If you don’t draw the line here, where will you draw it? Staying on X is morally indefensible. It is the Epstein Island of social media.
I should also point out that Grok is breaking the law in Ireland (which is where the EU operations of Twitter are based). Even that doesn’t seem to matter to those who continue to use the platform.
The Maynooth University Equality and Diversity Policy has been developed therefore, to realise these core values of equality, inclusiveness, social justice, dignity and respect.
I’d like to know how remaining on X aligns with these core values, and by what process Maynooth University came to a different conclusion on this than the Royal Irish Academy and other organizations mentioned above. One might well be tempted to infer that the above statement, like so many others produced by University Management, is mere bullshit. Perhaps “The Leadership” is waiting to see what other higher education institutions do before making a decision. But that wouldn’t be leadership at all, would it?
By way of a postscript to this let me share this petition which aims to discourage the sharing of content on X and replacement with Mastodon.
I make no apology for encouraging the use of Mastodon. BlueSky is better than X but Mastodon is much better than BlueSky in terms of both its functionality and its governance. It doesn’t have as much reach as other platforms, though, which is why I want to promote it. If I had my way, Maynooth would set up its own Mastodon instance, as the Dublin Institute for Advanced Studies has done, for example.
I removed the X icons from this blog some time ago. I can’t stop people sharing content from this blog on X, but I certainly don’t want to encourage it.
It was a great pleasure last night to be able to attend my first concert of 2026 at the National Concert Hall. It was a rainy evening in Dublin, but the auditorium was nevertheless packed. The only issue was that so many people were there, mostly with overcoats checked into the cloakroom, that it took a long time to get out at the end!
Before the performance
National Symphony Orchestra Ireland was conducted for the evening by guest conductor Anna Sułkowska-Migoń who directed a fine and varied programme of music.
The first piece (D’un Soir Triste; Of a Sand Evening) was by Lili Boulanger. I’ve heard a few pieces by her and found them all excellent, as was this one which is very atmospheric and packs a lot into the 12 minutes or so it takes to perform. The only reason Lili Boulanger is so much less famous than her older syster Nadia is that Lili suffered from ill health nearly all her life, eventually dying from tuberculosis just a few months after this piece was composed at the age of 24. Inevitably the number of compositions by her is very small, but as I said earlier everything I’ve heard by her is very good indeed. Her premature tragic death was a great loss.
After that piece there was considerable reorganization on the stage. The brass, woodwinds and percussion all left and space was made for the Steinway (between the conductor and the audience). Then we were joined by pianist Barry Douglas and trumpeter Darren Moore. The latter brough two trumpets with him, actually, of which more shortly.
The piece we were about to hear was listed in the programme as Concerto for Piano, Trumpet and String Orchestra (which is a more accurate description than the usual name Piano Concerto No. 1) by Dmitri Shostakovich. It’s quite hard to classify really, perhaps you could call it a Triple Concerto, but that doesn’t matter much. Music is much more important than how it is classified.
Although I admire the music of Shostakovich greatly, and look out for performances whenever I can, I had never heard this piece before. I was delighted by it. Written in 1933 when Shostakovich was only 27, it is instantly recognisable in style although I bit lighter and quirkier than one normally expects from that composer. Shostakovich had a wry sense of humour, but he often concealed his jokes to avoid getting into trouble. Not so in this piece, which is overtly playful and mischievous, rather than crypic
The trumpet plays a modest – indeed muted – part early on but, over the four movements, gradually becomes more prominent and at the end it delivers a series of exuberant fanfare-like figures as the key switches from C minor to close in C major. At this point I should given special mention to Darren Moore, Principal Trumpet of the NSOI, who played beautifully. He swtiched trumpets just before the end, where the trumpet is required to be louder and more assertive. I’m going to hazard a guess that he switched to a C trumpet for the closing stages, perhaps from a standard B♭ trumpet used earlier. I’ve heard it said that a C trumpet produces a brighter and cleaner sound, and it certainly did sound different from the other trumpet. If I am right it means that the piece concluded with none of the instruments on stage being transposing instruments.
Now a couple of questions for my readers. I have known some jazz trumpeters over the years and they all played B♭ trumpets. On this basis I always assumed that trumpets in classical orchestras would be B♭ instruments. Now I’m not sure this is true. Do trumpet players in classical orchestras usually use B♭ instruments, or does practice vary? A follow-up question is whether orchestral parts for trumpets and other transposing instruments are scored differently, or are the musicians required to do any transposition themselves? (If I had to bet I’d wager that professionally-trained classical musicians can transpose on sight.) Answers and comments through the comments box please.
Anyway, the hugely enjoyable performance was greeted with cheers and generous applause not only for the excellent soloists Barry Douglas and Darren Moore but for the whole Orchestra.
After the wine break we had a much more familiar work, the orchestral suite Scheherazade by Nikolai Rimsky-Korsakov. Pieces from this suite – especially the first section, The Sea and Sindbad’s Ship – often find their way into collections of popular classics and it is probably Rimsky Korsakov’s greatest hit. It’s inspired by the One Thousand and One Nights although there are only four movements, not 1001! The composer certainly included something for all sections of the orchestra, but there was especially beautiful playing by Elaine Clark (leader). I enjoyed this performance too, mainly as a bit of colourful escapism as did the audience, who have it another standing ovation.
Then it was into the queue to collect my coat and thence on foot to Pearse station for the train back to Maynooth. The rain had stopped by then.
The last day of a week dominated by examination marking found me briefly back on campus to return the batch of scripts I have finished corrrecting and collect the next set (which, happily, is much smaller):
There are 14 scripts in the pile for my second paper, for my 4th year Mathematical Physics module on Differential Equations and Complex Analysis, around one-third of those for my Engineering Mathematics module Differentiaol Equations and Transform Methods. Based on the total number of examinations I have to mark I am therefore now 50% complete, but based on the number of scripts I’m about 75% through. I should be able to finish the latest batch in a day, but there’s no desperate rush so I’ll do them on Monday. I’m not going to start them now as I am off a concert – my first of 2026 – this evening and I prefer not to work at weekends unless I absolutely have to.
I finished the first set of marking yesterday, and spent most of this morning uploading and checking the scores and the conflation of exam marks with coursework scores. Satisfied that all is OK, I returned the scripts to the office for storage until our Examination Board meeting in about 10 days. I wasn’t on campus long, but there was a fire alarm in the Science Building while I was there. As usual, it turned out to be a false alarm.
Anyway, I should be finished with examination matters by Monday evening, which gives me four days next week to get on with other things. I’m looking forward to the change.
Lecturers at Maynooth University are supposed to be available on the telephone to deal with queries from students concerning their examinations. And so it came to pass that yesterday I was “on call”. Since I live in Maynooth, I decided to come into campus in case of a query so I could go to the examination venue l to deal with it if required. In the event, however, the examination passed off without incident and nobody called.
I wasn’t twiddling my thumbs all morning though. It seemed a good opportunity to go through the accumulated coursework for this module, applying various exemptions for medical or other reasons, so that when I’ve marked the scripts I can immediately combine the results with the CA component.
The examination venue, incidentally, was not on campus but in the Glenroyal Hotel in Maynooth. The Sports Hall on campus is usually one of the places for examinations to be sat, but it is not available this year due to refurbishment. The other day I was in one of the shops in the shopping centre next to the hotel and there were some complaints about the lack of available car parking spaces owing to so many students parking there for their exams. Anyway, the exam scripts found their way to my office this morning and here I am again, back home with a stack of an examination scripts to mark. The picture shows about 40 papers from my module on Differential Equations and Transform Methods. I want to get them out of the way as quickly as possible as I have another paper coming up on Thursday and have a lot of other things to do before term starts at the beginning of February. All the usual displacement activities having been exahusted, I’ve already made a start. With a bit of luck I’ll complete this task by Thursday.
I’ve often discussed the process of marking examinations with my colleagues and they all have different techniques. What I do is mark one question at a time rather than one script at a time. What I mean by that is that I go through every script marking all the attempts at Question 1, then I start again and do Question 2, etc. I find that this is much quicker and more efficient than marking all the questions in each script then moving onto the next script. The reason for this is that I can upload into my mind the model answer for Question 1 so that it stays there while I mark dozens of attempts at it so I don’t have to keep referring to the marking scheme. Other advantages are that it’s easier to be consistent in giving partial credit when you’re doing the same question over and over again, and that also you spot what the common mistakes are more easily.
Anyway, I’ve decided to take a break for today. I’ll start again tomorrow.
For last year’s words belong to last year’s language And next year’s words await another voice. And to make an end is to make a beginning.

So it’s New Year’s Day. Athbhliain faoi mhaise dhaoibh!
For me this brings the festive season to an end. I’ve been eating and drinking too much for the last week as one is supposed to. Last night I brought in the new year with a dish of roast duck and the last of the Christmas vegetables. I think I’ll be buying any sprouts and parsnips for a while. When the iron tongue of midnight told twelve, I had a glass of excellent Irish Whiskey in the form of Clonakilty Single Pot Still (46%). It has been a most enjoyable week, but heightened level of self-indulgence has been rather exhausting, and I’ll be taking things a bit easier for a few days before I go back to work on Monday. It’s hard work being a glutton.
Anyway, I thought I’d mention a few things looking forward to the New Year.
January will, as usual, be dominated by examinations, and especially the marking thereof. The first examination for which I am responsible is on January 12th. The examination, incidentally, will be held in the Glenroyal Hotel in Maynooth as the Sports Hall on campus – usually a major exam venue – is out of commission due to building work.
I have a couple of writing deadlines, in addition to having to correct the examinations, so it will be a busy January.
Then February sees the start of a new semester. I’ll be teaching Particle Physics again. I was a bit surprised to be asked to teach this again, as I was filling last year in for our resident particle physicist who was on sabbatical. I’m glad to be able to continue with it given the work I put in to do it last time. My other module is Computational Physics which I have taught at Maynooth every year since 2018, apart from 2024 when I was on sabbatical. This time, however, I will have to think hard about how to deal with the use of generative AI in the coursework.
Will I get to teach any astrophysics or cosmology at Maynooth before I retire? That’s looking very unlikely. I think it’s probable that the new academic year, starting in September, will find me teaching the same modules as last year.
The year ahead will also see the first data release (DR1) from the European Space Agency’s Euclid Mission. The date for that will be October 21st 2026. This is a hard deadline. There’s a huge amount of work going on within the Euclid Consortium to extract as much science as possible from the observations so far before the data becomes public, but you’ll have to wait until October to find out more!
This reminds me that I forgot to share this nice image from Euclid that was released just before Christmas.

Once upon a time, WordPress used to send an email about the year’s blog statistics, etc, but it stopped doing that some time ago. I checked this morning, however, and learned that traffice on the blog in 2025 was up by 2.6% since 2024. I’m not sure how meaningful this is, because there is so much scraping going on these days. That figure doesn’t include the people who get posts via email or RSS or via other platforms such as the Fediverse.
While I’m on about social media I’ll mention a stat about my Bluesky account. I joined Bluesky in 2023 when I abandoned Xitter. As of today I have 8,078 BlueSky followers, which is more than I ever had on X, and with far higher levels of engagement and much friendlier interactions.
I’m also on Mastodon, although with a much smaller following (1.4k). This blog also has a separate existence on Mastodon here. I very much like the federated structure of Mastodon (which, incidentally, accords with my view of how academic publishing should be configured) and am a bit disappointed that it doesn’t seem to have caught on as much as it should.
That disappointment pales into insignificance, however, with the outrage I feel that my employer – along with most other universities – persists in using Xitter. Touting for trade in a far-right propaganda channel is no way for a institution of higher education to behave. You can read my views on this matter here.
And finally there’s the Open Journal of Astrophysics. The year ahead will see the 10th anniversary of our first ever publication – on an experimental prototype platform, long before we moved to Scholastica. It will be next Monday before we resume publishing, starting Volume 9. Which author(s) will be the first to get their final versions on arXiv in 2026? Stay tuned to find out!
I’ve just returned to the office after delivering my last teaching session of 2025 (a tutorial on Differential Equations and Complex Analysis). I’m up to date with all my grading too, so I’m done with teaching for 2025.
Yesterday we had our Physics Department Christmas Celebration, which was very enjoyable. We went to a restaurant in Maynooth (The Avenue) and afterwards to a local pub (Brady’s). I didn’t stay out too late, though, because I had teaching today and I’m too old for that sort of thing. I got up quite early this morning, actually, although I have to admit it took even longer than usual for effective brain functioning to commence…
I was planning to go home directly after my tutorial and finish a few small jobs in my study, but I don’t particularly want to get drenched so I think I’ll finish them here on campus and hope that the current deluge passes soon…
This paper reminded me of a paper I wrote a long time ago (in 1991, when I was at Queen Mary) about primordial magnetic fields and galaxy formation. It had its origins in a lunchtime talk I gave which was based on an old paper from the 1970s by Ira Wasserman. All I did was go through the paper and add a few small comments to update it, including some more recent observational constraints and mentions of dark non-baryonic matter; the Wasserman paper was framed in a model in which all the matter in the Universe was baryonic.
Anyway, the talk went down quite well and I was encouraged to write it up. I did so, and submitted it to a journal (MNRAS). Not unreasonably, it was rejected on the grounds that it didn’t have sufficient original content. I therefore expanded the discussion and submitted it as a review article to Comments on Astrophysics. That journal is now defunct, but the paper can be found on NASA/ADS here. It’s even got some citations!
You will see I was advocating a larger magnetic field than in the recent one, with a view to affecting galaxy formation directly rather than larger scale features of the Universe. An important point is that primordial magnetic fields can have a large effect soon after recombination, so they might play a role in the formation of galaxies at high redshift which we are struggling to explain. At least – unlike some of the more exotic explanations that have been proposed – we know that magnetic fields actually exist…
The week ahead is the last week of the teaching term at Maynooth and, since I don’t have any sessions scheduled for Friday 19th December, I will finish on Thursday 18th and take the Friday off. I don’t think there’ll be many people – either staff or students – around on Friday anyway.
Tomorrow (Monday) is the infamous “Student Xmas” in Maynooth where many undergraduates spend the day getting drunk rather than attending lectures or tutorials. Many start drinking in the morning and carry on until the pubs close in the early hours. I wouldn’t mind this excess too much, but the town is usually in a terrible mess on Tuesday morning, with fast food containers, broken bottles and vomit littering the streets. I have a lecture at 2pm on Monday (tomorrow) which will go ahead and a telecon at 4pm. After those I’ll be making my way home and keeping well out of it until I have to navigate a passage through the debris on Tuesday morning.
Two pubs, Brady’s amd The Roost promote this pre-Chrtistmas celebration vigorously on social media. I imagine their takings are substantial. I wonder if they – or indeed the Student’s Union – pay a little to help clear up the aftermath?
On Tuesday I have three lectures, but one of them (at 11am) will be the final class test for Differential Equations and Complex Analysis so there’s little for me to do but sit there, invigilating. I have promised to get the answers corrected and returned before the break so I’ll have to do them by Thursday, the date of the last tutorial. Our Department Christmas Celebration is on the afternoon of Wednesday 17th, so I’ll have to fit the grading in on Tuesday evening or Wednesday morning.
The other two lectures on Tuesday are Engineering Mathematics, followed by another on Wednesday. I was going to use one of the Tuesday slots for the final class test for this module, but a number of students asked me to postpone it because they anticipate being hung over. I don’t mind but the only available time with a suitable room is Thursday, so they won’t get their marks until after the holiday, for which I feel no need to apologise. It’s good to have the three lecture slots because I missed an hour last week because of the power cut owing to Storm Bram.
