The Government of Ireland has just announced details of a scheme called Global Talent Ireland. Full details of the scheme can be found here but, in a nutshell, the scheme aims to attract exceptional mid-career and established researchers from across the globe to Ireland. Researchers funded through this programme are required to transfer their research activities from their current location to any Eligible Research Body in Ireland. Given its commitment to equality, diversity and inclusion, Research Ireland welcomes applications from women and those from historically underserved communities.
The programme budget includes the resources to build a research team (e.g., staff, consumables and travel) to carry out high-impact, world-class research, and additional start-up costs to support the researcher’s move to Ireland. These positions are available for any area of research supported by Research Ireland.
The programme comprises two streams: Rising Stars and Research Leaders. High level details are outlined in the table below:
The timescale for this is very short (as the window lies in the vacations for people likely to be recruited). In the case of Maynooth, which I assume is an Eligible Research Body, there is a first-stage internal process for Expressions of Interest to be completed by 29th July (i.e. less than two weeks away). There is then a selection for submissions to be forwarded to the Government by August 28th 2025.
As the timescale is so short I would ask anyone interested in taking up such a position in the Department of Physics at Maynooth University to contact me as soon as possible, as both the Head of Department and Dean of the Faculty of Science and Engineering are away at the moment. Ireland’s recent decision to join CERN as well as membership of the European Southern Observatory and the European Space Agency might be good strategic grounds for an application.
Those interested in other areas of research would be advised to contact the relevant Departments as soon as possible. The selection process is bound to be very competitive, but you can’t win the prize if you don’t buy a ticket!
Though not as warm as it has been over the last few days, today still found Maynooth University Library Cat in need of a siesta. There aren’t many students around these days so he’s not disturbed by so many people wanting to pet him, and was sound asleep in a shady spot when I passed by this afternoon.
This is a big weekend for fans of hurling, as we have reached the semi-final stage of the All Ireland Senior Hurling Championship. Yesterday Cork trounced Dublin by 7-26 to 2-21. I’ve never seen such a high scoring game at the top level, nor a margin as large as 20 points (a goal is worth 3 points)! Though not expected by many to progress, Dublin had deservedly beaten Limerick in the quarter-finals but they were never in the game yesterday.
The other semi-final takes place this afternoon at 4pm, and is between Kilkenny and Tipperary. Which of these will meet Cork in the Final? We’ll soon find out!
Update: it was another high scoring match, finishing Kilkenny 0-30 to Tipperary’s 4-20, so Tipperary won by 2 points (with a goal in the last minute). The All Ireland Final will therefore be between Cork and Tipperary.
Both semi-finals are held at Croke Park, as is the final. Many supporters come through Maynooth on their way to these matches, as we’re on the train line that goes into Dublin Connolly via Drumcondra (the nearest station to Croke Park). There is an arrangement by which supporters can park their cars at the GAA ground in Maynooth and take the train, as there is no chance of parking near Croke Park.
Yesterday evening I needed to do a quick trip to the shops and ran into a crowd of returning Cork supporters who had just arrived by train. Most fans were in very good humour (unsurprisingly) but a few were very much the worse for drink: one young lad had passed out on the footpath and concerned pedestrians called an ambulance; over the road at the bus terminus Gardaí were dealing with a drunk and aggressive person; and in Supervalu a hopelessly inebriated bloke staggered into the off-licence part to get more booze but ended up falling over and dropping the cans he had picked up, with one bursting and making a mess all over the floor.
Anyway, none of this is to do with the intended subject of this post. Cork’s victory yesterday reminded me of a little bit of hurling information that I found interesting, concerning the way to hold the hurley. Having been brought up on a different bat-and-ball game (cricket), I was surprised to learn that in hurling you are supposed to hold the bat the wrong way round! What I mean by that is that in cricket the batter holds the bat with the dominant hand at the bottom of the handle near the blade and the other hand at the top. For illustration, here’s a forward defensive shot played by a right-hander:

For illustration, on the left, there’s a forward defensive shot played by a right-hander. You can see the left hand at the top of the handle and the right hand near the bottom. Shots like this are played predominatly with the bat moving in a vertical plane, guided by the left hand with the right hand guiding the direction. A hook or pull shot is played with the same grip but swinging the bat across the body from right to left with more bottom hand.
When I was at school I tried batting left-handed in the nets. It was quite interesting. I found I could play defensive shots equally well that way as with my usual right-handed stance, but I couldn’t play attacking shots very well at all.
It’s the same arrangement in baseball (or rounders, as we call it on this side of the Atlantic). The batter will hold the bat with their weaker hand nearer the end of the handle, i.e. towards the thin end.
On the other hand (!), a hurler holds the hurley the other way round. On the right you can see a hurler at the ready position, with his right hand at the top of the handle and the left hand near the blade. When striking the sliotar (ball), the hands are moved closer together. Holding the end of the hurley in the dominant hand means that more strength can be applied when reaching away from the body with one hand, something that isn’t really done in cricket. The typical long-range strike of the sliotar is rather like a hook shot in cricket, except it’s played the opposite way across the body.

Here’s a video:
This seems very unnatural if you have been brought up to use the opposite basic grip, which explains why so many struggled even to hit the sliotar at the practice at the EAS Social Dinner in Cork a couple of weeks ago. In Ireland, however, kids learn to play hurling when they’re still in kindergarten so this is instilled at a very early age.
The summer examinations at Maynooth being over and the finalists having received their degree results I was reminded that I’d missed the anniversary of my own graduation. The main reason for that is that I couldn’t remember the date. I thought it was in July, actually, but rummaging through my files reminded me that it was on Saturday 22nd June 1985. Maynooth graduands will have to wait until September at the earliest for their conferring ceremony.
The degree certificate, incidentally, is not at all fancy. The only thing that surprised me about it was that it’s not in Latin!
The one I got when I collected my DPhil from Sussex University is far more elaborate. It’s also worth mentioning that although I did Natural Sciences (specialising in Theoretical Physics), the degree I got was Bachelor of Arts.
I don’t remember much about the Cambridge graduation, perhaps because the previous evening (Friday 21st June) we were plied with alcohol at the MacFarlarne-Grieve Dinner (a special event for graduands), then finished up in The Pickerel, the closest pub to the College. Our ceremony started at 9.15am and I wasn’t the only person graduating with a hangover.
The whole ceremony was dpme in Latin (or was when I graduated) and involved each graduand holding a finger held out by their College’s Praelector and then kneeling down in front of the presiding dignitary, i.e. either the Vice-Chancellor or Deputy Vice-Chancellor. I can’t remember which. The magic formula that turns a graduand into a graduate is:
Auctoritate mihi commissa admitto te ad gradum Baccalaurei in Artibus, in nomine Patris et Filii at Spiritus Sanctii
Other than that, and the fact that the graduands had to walk to the Senate House from their College through the streets of Cambridge, I don’t remember much about the actual ceremony.
After the ceremony we returned to Magdalene College for a garden party. I found this quite stressful, because my parents had divorced some years before and my Mum had re-married. My Dad wouldn’t speak to her or her second husband. At the garden party, the two parts of my family occupied positions at opposite corners of the lawn and I scuttled between them trying to keep everyone happy. It was like that for the rest of the day and I was glad when it was all over.
Anyway, the following October I started as a research student at the University of Sussex doing a Doctorate in Philosophy. I finished my thesis in 1988. Those three years were hard work but, on the whole, very enjoyable. I have a similar length of time in front of me before I retire. By the end I’ll have had 40 years in higher education (29 in the UK and 11 in Ireland). Hopefully, by then I’ll have figured out what to do when I leave University.
This morning I took an impromptu trip to Trim, which is situated in the Boyne Valley in County Meath. There has been a small astrophysics workshop going on there this week, attended by some people I know including a couple of old friends from Nottingham, Frazer and Meghan. Trim is less than 30km from Maynooth as the crow flies. Unfortunately I couldn’t find a crow willing to offer me a lift, public transport from Maynooth to Trim is difficult, and I don’t drive, so it wasn’t easy to arrange to meet up. Fortunately this morning one of our postdocs was driving up for the morning session of the meeting so I cadged a lift and and stayed until lunch before getting a lift back to Maynooth.
It was a nice trip. An added bonus was that the workshop venue was just a few metres away from the historic Trim Castle, which was built in the early 13th Century. We had time for a quick walk around before leaving to return to Maynooth.


As you can see, it’s a standard model Norman castle. The Keep, though not entirely intact is pretty well preserved; there’s certainly a lot more left than in the case of Maynooth castle. Quite a lot of the curtain wall and the gates have survived quite well too. In order to get inside the Keep (and climb to the top) you have to take an official tour, but we didn’t have time for that.
Today is Consultation Day here at Maynooth University and, in the course of being consulted, I was reminded that this period, being immediately after undergraduate final results are released to students, is a potentially a good time to advertise our local postgraduate course to prospective applicants.
I therefore decided o use the medium of this blog to advertise the fact that the MSc in Theoretical Physics & Mathematics at Maynooth University is open to applications for entry in September 2025.
This postgraduate course is run jointly between the Departments of Physics and Mathematics & Statistics, with each contributing about half the material. The duration is one calendar year (full-time) or two years (part-time) and consists of 90 credits in the European Credit Transfer System (ECTS). This is split into 60 credits of taught material (split roughly 50-50 between Theoretical Physics and Mathematics) and a research project of 30 credits, supervised by a member of staff in a relevant area from either Department.
This course is a kind of follow-up to the existing undergraduate BSc Theoretical Physics & Mathematics at Maynooth, also run jointly. We think the postgraduate course will appeal to many of the students on that programme who wish to continue their education to postgraduate level, though applications are very welcome from suitably qualified candidates who did their first degree elsewhere.

I saw this on my way into work this morning. I wonder if anyone can identify it? I don’t know fungi.
My PictureThis app could only identify it as some form of Agaricus, i.e. one of the Agaricaceae. I know it has a fly on it, but that doesn’t mean it is Fly Agaricbut it has also been suggested to me that it might be Amanita Strobiliformis. I’m not convinced by either of these. Does anyone have any suggestions?
Update: a day later, it has evolved!
It’s now starting to look very much like it is indeed Macrolepiota Procera (the Parasol Mushroom), and it is now opening its parasol. I expect tomorrow it will be even flatter.
Update: it is indeed looking flatter, but not in the way I imagined. Somebody squished it.
Being so busy for the last couple of weeks I omitted to engage in the gratuitous self-promotion that one would expect from a blogger, so I’m remedying that today by pointing out that I’m co-author of a new paper that is now on arXiv. This has already gained a bit of traction in the media, e.g. here.
Here is the abstract, which also shows the author list:
(I’ve just noticed that it says “The Netherland”, instead of “The Netherlands”. Oops!)
For those of you not in the field, there is currently a big mystery about how galaxies we have found at high redshift with JWST managed to acquire massive black holes so early in the Universe’s evolution. Black holes can grow quickly in a dense environment by accreting mass onto an initial seed, but what are the seeds? In this paper we investigate the possibility that they were primordial black holes. These form directly from fluctuations in the early Universe, as opposed to astrophysical black holes which form from stellar collapse. We don’t know exactly what mass primordial black holes would have nor how numerous they would be, but this paper uses high-resolution numerical experiments to investigate their effects if they do exist.
Here’s a pretty picture which is a zoom into 200 pc of the full simulation. I think 10pc counts as high resolution for a cosmological simulation! The blue circle shows the most massive PBH in the simulation, the green circle shows its nearest neighbour. The colour scale represents the number-density of dark matter particles.
For more details, read the paper!
