De Valera Connections

Posted in History, mathematics, Maynooth, Television with tags , , , , on September 11, 2025 by telescoper

On September 4th, when I posted a piece about the forthcoming Presidential Election in Ireland, I forgot to mention that just two days earlier was the 50th anniversary of the funeral of Éamon de Valera, founder of Fianna Fáil (one of the two largest political parties in Ireland) and architect of the Irish constitution, who died on 29th August 1975 at the age of 92. Here’s some coverage at the time by (British) Movietone News, the commentary is rather generous to him:

De Valera (nickname `Dev’) is an enigmatic figure, who was a Commandant in the Irish Republican Army during the 1916 Easter Rising, but despite being captured he somehow evaded execution by the British. There’s no evidence, incidentally, that he escaped the firing squad because he was born in America. Dev subsequently became Taoiseach (Prime Minister) and then President (Head of State) of the Irish Republic.

There’s no question in my mind that de Valera is the most significant Irish politician of the 20th Century, which is not to say I fid him an agreeable figure at all and his legacy isn’t particularly positive. Nevertheless, his funeral was perhaps as significant event for the Irish as that of Winston Churchill had been for the British just a decade earlier.

Over the past couple of weeks RTÉ television broadcast a two-part documentary called Dev: Rise and Rule; the second part was on last night. It is quite nicely made, but disappointingly superficial and lacking in any real historical insight. The suggestion that it would “decode” Dev was unfulfilled. This is a pity because RTÉ often does good documentaries.

Anyway, this gives me an excuse to mention again, Dev’s connection with Maynooth. De Valera was a mathematics graduate, and for a short time (1912-13) he was Head of the Department of Mathematics and Mathematical Physics at St Patrick’s College, Maynooth, which was then a recognised college of the National University of Ireland. The Department became incorporated in Maynooth University when it was created in 1997. Mathematical Physics is no longer a part of the Mathematics Department at Maynooth, having first become a Department in its own right, then changing its name to the Department of Theoretical Physics and then, just last year, being subsumed within a new Department of Physics.

De Valera missed out on a Professorship in Mathematical Physics at University College Cork in 1913. He joined the the Irish Volunteers, when it was established the same year. And the rest is history. I wonder how differently things would have turned out had he got the job in Cork?

A New Department of Physics

Posted in Biographical, Education, Maynooth with tags , , , on September 2, 2024 by telescoper

My first official day back at work after a year-long sabbatical coincides with the first official day of a new Department of Physics at Maynooth University:

I knew this was happening, of course, and it should have happened years ago. Having two separate Physics Departments at Maynooth was not just an oddity. It required the relatively small number of academic staff across the Departments to undertake a huge amount of duplication in teaching thereby wasting resources and increasing workloads. Even combined together, the total complement of 15 academic staff means that we’re still a very small Department.

There are, therefore, potential benefits in this merger but they will take time to accrue. At the moment it only exists on paper, and staff in the two ex-Departments will have to work out what to do next in terms of coordinating teaching and research. In my opinion this all should have been planned and agreed before going ahead, but here we are. We just have to make the best of the situation presented to us by The Management.

For the time being the New Department is just the two Old Departments in a single wrapper. We were already located side-by-side in the same building, the Science Building so there are no large-scale relocations of staff, at least not yet. All existing courses remain the same as before, too. That’s just as well, really, as we start teaching in three weeks!

That’s not to say that nothing has changed. The number of postgraduate and postdoctoral researchers in the Department of Theoretical Physics has been growing and there was consequently a drastic shortage of office space. My return from sabbatical has involved me being granted an elevated status in the new Department: I’ve been moved upstairs out of the old Theoretical Physics Department to an office in the old Experimental Physics Department.

Here’s a question, though. My contract of employment says that I am employed in the Department of Theoretical Physics. Since that Department no longer exists, do I need a new contract or have I been made redundant?

P.S. I wrote this blog at home before going to the office as this blog remains banned on Maynooth University campus.

Mathematical Mystics at Maynooth

Posted in History, mathematics, Maynooth with tags , , , on January 25, 2024 by telescoper

I’m indebted to my colleague David Malone for sending me this small excerpt from an old issue of the Kalendarium of St Patrick’s College, Maynooth, dating back to the 1960s, which deals with the appointments of new members of staff

Halfway down you will see a reference to Mathematical Mystics!

This is obviously a mistake. It should of course be Mathematical Psychics Physics. I also think the name of the Mathematical Mystics lecturer should be Tigran Tchrakian. I think these are both transcription errors from somebody’s very bad handwriting! The current Department of Theoretical Physics at Maynooth was formerly known by the title Mathematical Physics.

There are some other points of interest. in Experimental Physics you will find mention of a young Susan Lawlor who is now better known as Susan McKenna-Lawlor, a very eminent astrophysicist who specialized in space instrumentation, now in her eighties.

I’m also amused by the existence of a lecturer in Elocution

The historical background of St Patrick’s College is that it was primarily a Catholic theological institution (founded in 1795) although it taught secular courses and was a recognized college of the National University of Ireland from 1910. It was only in the mid-1960s that it was opened to lay students, which expanded the numbers considerably. In 1997 that the secular part separated and formed NUI Maynooth (now known by the marketing people as Maynooth University). The remaining theological institution is known as St Patrick’s Pontifical University (or St Patrick’s College or just Maynooth College).

A major role for St Patrick’s College was the training of priests and I suppose it was important that priests should be well spoken, hence the lectures on elocution…

Near the top in connection with Sociology you can see the title An tAth which is the Irish language way of writing the abbreviation “Fr” for “Father”, indicating a priest; “father” is athair and the an is a definite article. Note the lower case t in front of Ath which is an example of prothesis.

Finally, right at the top of the page you can see the name Donal Linehan, which will be familiar to Irish rugby fans but I don’t know if there’s a family connection between the former Ireland intentional who is now a TV commentator and the lecturer in Roman and Civil Law.

The Higher Education Market

Posted in Education, Maynooth with tags , , , on September 3, 2023 by telescoper
Iontas Lecture Theatre, Maynooth University

Last week I was talking to a current undergraduate student who has been working in the Department of Theoretical Physics over the summer. After a while the conversation turned to the possibilities for postgraduate education. I’ve had that sort of discussion many times over the years with many different students, but the curious thing is that I always find it quite difficult because I’m torn between competing motivations.

On the one hand, there is the wish to have the best undergraduates stay on for further study in the Department. That of course helps our research, but it is also good for our finances as postgraduate students bring income. I think we offer good opportunities at both Masters and Doctoral levels, so it’s not too difficult to point these out to students in a way that at least some find persuasive.

On the other hand, there is the fact that I am an academic not a salesman and I feel that it is my responsibility to give honest guidance. The fact is that a good undergraduate degree from the National University of Ireland will open a lot of doors elsewhere, and these should be considered. At Masters level in particular, there are excellent courses available in the EU which have the advantage of not charging fees at the level they are charged in Ireland. Add to that the cost of living and accommodation crises. It’s no surprise that many of our graduates seize opportunities to go to postgraduate study in Germany, Denmark or The Netherlands (to name just a few). I have no problem with explaining the advantages of options outside my own Department and no doubt some students find these points persuasive too.

There’s a wider context for this type of dichotomy, namely the progressive marketisation of higher education. When it comes to recruiting undergraduate students we academics are increasingly required to act as reps for the University, hawking our wares at Open Days, Recruitment Fairs, and a variety of online events. I’m reasonably happy to participate in these when asked to do so, but I always take the approach of describing what we do in our Department rather than trying to do down what happens elsewhere. I’m an academic not a salesman. And I work in a public university, not a private business. I see my job as giving advice in as objective a way as possible. If I feel that our courses would not be the right choice for a student, I’ll explain why. In the end, of course, the decision is up to the student, but I feel obliged to give them enough information to make an informed choice.

A couple of years ago, the (then) new President of Maynooth University walked up to the Theoretical Physics stand at a Maynooth Open Day when I was on duty. The first thing she said was “Sell your course to me”. I described what we had on offer, but I don’t think what I said impressed her at all. We can only hope to succeed in recruiting students who have some interest in science. An Open Day is a bit late to cultivate that: interest has to be nurtured from an early age.

Another problem I find, speaking as a physicist (though this is probably also true for people in many other disciplines), is that we see physicists in other institutions as colleagues rather than business rivals. This is particularly true for those of us working in large consortia that spread over many departments (and indeed many countries). I therefore see myself as a physicist who happens to work at Maynooth University rather than as an employee of Maynooth University who happens to do physics. It’s not that I am disloyal to my employer, it’s just that I have a greater loyalty to a larger community.

I do understand that the reality of the funding system here means that we have to be able to recruit students in order to pay our way, but I feel that the way to achieve that is by establishing a strong reputation in our core academic mission of teaching and research rather than through marketing gimmicks, corporate branding, or other forms of commercial flummery. No amount of propaganda will disguise a higher education institution that neglects those things that higher education is about.

No Tension at Redshift Ten

Posted in Maynooth, The Universe and Stuff with tags , , , , , on April 29, 2023 by telescoper

I know it’s the Bank Holiday weekend but I could resist a quick post about a new paper that hit the arXiv yesterday (where all new astrophysics papers worth reading can be found). It is led by Joe McCaffrey who is a PhD student in the Department of Theoretical Physics at Maynooth University. The paper has been submitted to the Open Journal of Astrophysics, but obviously I am conflicted so have assigned it to another editor.

UPDATE: the paper is now published here.

As many of you will be aware, there’s been a considerable to-do not to mention a hoo-hah about the detections by JWST of some galaxies at high redshift. Some of these have been shown not to be galaxies at high redshift after all, but some around z=10 seem to be genuine.

Anyway, the abstract of Joe’s paper is this:

Recent observations by JWST have uncovered galaxies in the very early universe via the JADES and CEERS surveys. These galaxies have been measured to have very high stellar masses with substantial star formation rates. There are concerns that these observations are in tension with the ΛCDM model of the universe, as the stellar masses of the galaxies are relatively high for their respective redshifts. Recent studies have compared the JWST observations with large-scale cosmological simulations. While they were successful in reproducing the galaxies seen in JADES and CEERS, the mass and spatial resolution of these simulations were insufficient to fully capture the early assembly history of the simulated galaxies. In this study, we use results from the Renaissance simulations, which are a suite of high resolution simulations designed to model galaxy formation in the early universe. We find that the most massive galaxies in Renaissance have stellar masses and star formation rates that are entirely consistent with the observations from the JADES and CEERS surveys. The exquisite resolution afforded by Renaissance allows us to model the build-up of early galaxies from stellar masses as low as 104 M⊙ up to a maximum stellar mass of a few times 107 M⊙. Within this galaxy formation paradigm, we find excellent agreement with JADES and CEERS. We find no tension between the ΛCDM model and current JWST measurements. As JWST continues to explore the high redshift universe, high resolution simulations, such as Renaissance, will continue to be crucial in understanding the formation history of early embryonic galaxies.

arXiv:2304.13755

The key figure is this one:

The solid curves show the number of galaxies of a given mass one would expect to see as a function of redshift in fields comparable to those observed with estimated values from observations (star-shaped symbols). As you can see the observed points are consistent with the predictions. There’s no tension, so you can all relax.

The Week Ahead

Posted in Biographical, Maynooth with tags , , , , , on August 28, 2022 by telescoper

I’m aware that tomorrow (Monday 29th August) is a Bank Holiday across the Irish Sea, but here on the Emerald Isle we had our August Bank Holiday at the start of the month so tomorrow I’ll be working. Among the important events to take place next week is the final Examination Board of 2021/2 on Wednesday morning at which we see all the results of all the students not just those from our Department. After that final check the marks will be released to students on Friday 2nd September and they’ll be able to discuss their situation with staff on Consultation Day which is Tuesday of next week (6th September).

The term of my appointment as Head of the Department of Theoretical Physics ends on Wednesday August 31st. I did try to step down a year ago. Here is what I wrote then:

Over the last few days, in an exhausted and demoralized state, I have been looking back over the best part of two years I have been Head of the Department of Theoretical Physics at Maynooth University – most of which has coincided with the Covid-19 pandemic. Frankly, I have found the burden of administration on top of the heavy teaching load required of me to be unmanageable. Because we are a very small Department teaching a full degree course, all of us have to teach many more modules than is reasonable for for staff who are expected to do research as well. I had to teach five modules* last academic year; that would have been bad enough even without having to do everything online and without the additional and frequently onerous duties associated with the Head of Department. There is no prospect of that burden decreasing for the foreseeable future.

For reasons which now escape me I agreed to carry on for one more year until the end of the three-year term to which I was appointed. I regret that “the burden”, far from decreasing, has continued to increase, to the extent that last year we had to cope with staff shortages too.

As it happens I will be spending Thursday and Friday at the Irish National Astronomy Meeting which this year is at the historic Dunsink Observatory (just outside Dublin and not far from Maynooth). I was last there on a trip to Dublin many years ago so I am looking forward to seeing it again as well as listening to the talks. The programme seems very broad and varied, so it should be interesting. The last one of these I attended in person was in Armagh in 2019, before Covid intervened and meetings became virtual. I’m not giving a talk this time, so hopefully it will be a fairly relaxed occasion.

Knowing that I was due to step down as HoD on 31st August I booked a week’s annual leave the following week (5th-9th September inclusive). I have had very little opportunity to take holidays over the past three years, so I am looking forward to a little bit of peace and quiet before the academic term starts. Before that, however, I have two research papers which are almost finished and which I’d really like to submit by Wednesday (and another which will have to wait until I return from leave). I’ve had little time to do research over the last three years either.

This year’s Leaving Certificate results are due out on Friday 2nd September and first-round CAO offers go out on Thursday 8th August. There will then be a scramble to allocate places, but I shall be blissfully out of the way for at least part of that. I will of course be back for the start of teaching (for returning students on 19th September and for new students on 26th September). As I have mentioned before that there is a serious student accommodation crisis in Ireland which will probably disrupt the studies of many students. I have yet to hear of any steps that my institution is taking to mitigate the looming disaster. It’s going to be a very challenging Semester, even without being Head of Department.

Oh, and on Monday I will be attending a virtual briefing about the plans from my Union (IFUT) to ballot its members for industrial action, of which more anon….

New Term Ahead!

Posted in Biographical, Covid-19, Education, Maynooth with tags , , on July 28, 2021 by telescoper

I know that there are quite a few people out there who think the summer is one long holiday for academic staff. Well, it may still be July but after my 10 days away that’s the holidays over as far as I’m concerned. Still, ten days’ summer holiday is ten days more holiday than I got last summer.

Next week the Repeat Examination period begins; it lasts from 4th August to 14th August. Once again these examinations are online and once again they have to be supervised by a member of academic staff. I have five paper scheduled and have to be at the screen for all of them. Then there’s the marking, checking, collation and uploading of the marks which must be done by 18th August. After that there’s an Examination Board before the final submission of all the repeat exams by August 23rd.

Incidentally, I was just checking over my Semester 1 repeat examinations and it seems like decades since I taught those modules last Autumn! The pandemic has played havoc with the perception of time!

After the Repeat Examinations are done, I have the unenviable task of preparing teaching for the next academic year. Although I’m stepping down as Head of Department of Theoretical Physics at the end of September I am still in that position until then so that task falls to me. Quite apart from the continuing uncertainty about what the Covid-19 situation will be like at the start of term (20th September), I have to deal with the fact that three out of our six full-time permanent lecturers are not available for next year. One is retiring this summer, one is departing for a position in Germany and another is on sabbatical.

The appointment of a temporary lecturer to provide sabbatical cover is normal, but the two other departures have not been replaced with permanent staff but by two one-year temporary lecturers. None of these new staff will be in post until 1st September but will have to teach a full complement of modules from 20th September onwards. Half our modules will therefore have to be reassigned, which means that the organization of teaching for the new academic year is not just the usual slight rearrangement of the previous year’s assignments but a major overhaul.

Losing two of our permanent staff to be replaced by temporary staff will of course have a negative impact on our research but that doesn’t seem to be important.

On top of al this the University is pressing ahead with a complete reorganization in the form of a merger of the Departments of Theoretical Physics and Experimental Physics which it intends to force through by 1st October 2021…

While glad that we may at last be emerging from the pandemic I’m dreading the next two months, not only because of the huge amount that has to be done by the end of September, but also because I think that period is going to set the scene for the longer-term future. I know I’m not the only academic who fears the massively increased workload dumped on us during the pandemic is going to become, to use a hackneyed phrase, “the new normal”.

Job in Theoretical Physics at Maynooth!

Posted in Maynooth with tags , on May 19, 2021 by telescoper

Just a short post passing on the information that we have a fixed-term job available in the Department of Theoretical Physics at Maynooth University. You can find the details here.

The position is for one calendar year starting in September 2021. I know it is a short appointment, but it seems to me that it would provide a good opportunity for an early-career academic to gain some teaching experience while carrying on their research in a lively and collegiate Department.

The deadline for applications is 23.30 on Tuesday 8th June 2021 and you should apply through the Maynooth jobs portal here.

If you’d like to know any more please feel free to contact me privately.

Oh, and please pass this on to anyone you think might be interested!

Reminder: Job in Theoretical Physics at Maynooth!

Posted in Maynooth with tags , on March 7, 2021 by telescoper

I’ve got a very busy week in front of me as we head towards the St Patrick’s Week Study Break so I thought I’d take the time to remind you all while I remember that we have a fixed-term job available in the Department of Theoretical Physics at Maynooth University, the deadline for which is a week from today. You can find the details here.

The position is for 10 months, starting in September 2021, and is to provide teaching cover for Professor Jiri Vala who will be on sabbatical next year. He originally intended to take his sabbatical this academic year, starting in September 2020, hence the previous advertisement of this post, but it was postponed for reasons of Covid-19 and the previous position was not filled.

I know it is a relatively short appointment, but it seems to me that it would provide a good opportunity for an early-career academic, perhaps someone straight out of a PhD, to gain some teaching experience.

The deadline for applications is 23.30 on Sunday March 14th, i.e. about 4 weeks away, and you should apply through the jobs portal here.

If you’d like to know any more please feel free to contact me privately.

Oh, and please feel free to pass this on to anyone who may be interested!
