A Rambling Post

Posted in Biographical, Maynooth with tags , , , , on March 15, 2018 by telescoper

Thursdays are busy days for me, starting with a 9am lecture on Computational Physics in Physics Hall, followed in the afternoon by a two-hour laboratory session on the same subject. Today we did exercises on root-finding and numerical integration, but didn’t get through as many examples as I had hoped. In between I had a number of jobs to do, including a lunchtime meeting off campus with my landlord to pay the rent (which he collects in person). I was a bit late back for the lab and, after apologizing, complained that I was too old for all this running around. One of the students kindly said that `age is only a number’. I replied `I know, but unfortunately in my case it’s a rather large one..’

I now have a bit of a break from teaching in Maynooth. There is no teaching next week as it is `Study Week’ and Monday 19th March is a public holiday (for St Patrick’s Day, 17th March, which this year falls on a Saturday). Study week is followed by a week’s holiday because of Easter. Teaching resumes here on Tuesday April 3rd. Somewhat surprisingly the Easter break here is shorter than in the UK.

The four-week batch of strikes in UK universities over pensions in which I have been participating ends tomorrow, which means that I will be lecturing in Cardiff again next Tuesday (20th March). This lecture will be Lecture 8 of 11, with lectures 5, 6 and 7 missing in action (industrial action, to be precise). Cardiff students are then on vacation for three weeks for the Easter break, with lectures resuming on 16th April. All of this means that for the next three weeks I won’t have to do the mid-week trip from Cardiff to Maynooth (which I am beginning to find rather tedious). I plan to stay all next week in Wales and return to Ireland the following week, as I have been invited to give a seminar then at the Dublin Institute for Advanced Studies (which I have never visited before).

Anyway, all that rambling just serves to illustrate that it’s a complicated business being in a superposition of jobs. I’m looking forward to the summer, when my wavefunction will collapse onto Ireland (if I haven’t collapsed from exhaustion before that).

To end on a very sad note, I heard today that Emeritus Professor David Bailin passed away yesterday. I knew David from both times I was at Sussex (as a graduate student and postdoc in the 1980s, and as Head of School of Mathematical and Physical  Sciences from 2013 to 2016). He was a very fine theoretical physicist and a very nice man who was held in a very high regard by all who worked with him. Condolences to his family, friends and colleagues.

Back to Maynooth

Posted in Biographical, Cardiff, Maynooth with tags , , , on March 7, 2018 by telescoper

So here I am back in Maynooth. The University re-opened on Monday after being closed from Wednesday last week owing to the extremely bad weather. I’m told the snow was several feet deep and the town was virtually cut off until the weekend. There is still some snow lying here and there, but the thaw has begun and you can see the effect of the meltwater on the river (the Lyreen) that flows through town, which is usually no more than a little stream:

It’s not quite a raging torrent, but getting there!

At the moment there’s no sign of a resolution to the industrial action that’s affecting Cardiff University (as well as others in the UK) so I decided to travel to Ireland yesterday rather than my usual Wednesday. The flight over was virtually empty and so was Dublin Airport, so I got on the bus well ahead of schedule and made it back to my flat (which was cold, but otherwise all in order) in time to buy some groceries and make dinner. The panic-buying of bread had caused a shortage, but all seems to be back to normal again.

I had arranged for someone else to do last week’s Thursday lecture and Lab session so I could attend the event the IOP event I posted about, but as the campus was closed they were cancelled anyway and I now have to find a way to catch up. Do not worry, though, I have a cunning plan.

Unless there’s an announcement in the next couple of days that next week’s strike is off I plan to stay in Ireland over the weekend, which will give me the chance to explore Dublin a bit, something that my schedule has not so far allowed. Next week will be the fourth week of industrial action and the last of the current batch of strike days, this time a full week (having escalated from two, three and four days in the preceding weeks). If there is no resolution by then I don’t know what will happen, possibly an all-out indefinite strike. Nobody wants that, but there’s no doubt in my mind who is to blame for this dispute and it’s not the Universities and Colleges Union. However, there are some signs of movement, so let’s hope for a negotiated settlement. If not, I’m seriously thinking of trying to bring forward my full-time move to Maynooth. There’s little point continuing in my post in Cardiff if I’m going to be permanently on strike.

Anyway, I have a 9am lecture to give tomorrow so I think I’ll toddle off, get some tea and have an early night.

Maynooth in the Snow

Posted in Maynooth with tags , on February 28, 2018 by telescoper

There has been very little snow in Cardiff (so far) but there have been heavy falls in Maynooth. The above picture was tweeted by Maynooth University this morning, along with an announcement that the campus is closed today (and probably until Friday, as more snow is on the way).

Under normal circumstances I would be in Ireland from today until the weekend, but I have to be in London tomorrow (Thursday) so arranged cover for my teaching. Looks like teaching will be cancelled tomorrow anyway.

UPDATE: Maynooth University campus will be closed until Monday.

Whether I can make it to and from London, or whether the event I’m supposed to attend tomorrow will be cancelled, remains to be seen…

Learning Technology

Posted in Biographical, Cardiff, Education, Maynooth with tags , , , , , , , , on February 20, 2018 by telescoper

I’m just taking a tea break in the Data Innovation Research Institute. Today has been a very day as I have to finish off a lot of things by tomorrow, for reasons that I’ll make clear in my next post…

It struck me when I was putting on the brew how much more technology we use for teaching now than when I was a student. I think many of my colleagues make far more effective use of the available technology than I do, but I do my best to overcome my Luddite tendencies. Reflecting on today’s teaching makes me feel just a little less like a dinosaur.

This morning I gave a two-hour lecture on my Cardiff module Physics of the Early Universe which, as usual, I recorded using our Panopto system. Although there was a problem with some of the University’s central file storage this morning, which made me a bit nervous about whether the lecture recording would work, it did. Predictably I couldn’t access the network drives from the PC in the lecture theatre, but I had anticipated that and took everything I needed on a memory stick.

After a short break for lunch I checked the lecture recording and made it available for registered students via the Virtual Learning Environment (VLE), known to its friends as Learning Central. I use this as a sort of repository of stuff connected with the module: notes, list of textbooks, problem sets, model answers, instructions and, of course, recorded lectures. The students also submit their coursework assignment (an essay) through this system, through the plagiarism detection software Turnitin.

This afternoon the students on my Computational Physics course in Maynooth University had a lab test, the first of four such tests, this one consisting of a short coding exercise. There are two lab sessions per week for this class, one on Thursdays (when I am normally in Maynooth to help supervise) and another on Tuesdays (when I am normally in Cardiff). I have a number of exercises, which are similar in scope but different in detail (to prevent copying) and the Tuesday lab has a completely different set of exercises from the Thursday one. In each exercise the students have to write a simple Python script to plot graphs of a function and its derivative (computed numerically) using matplotlib. The students upload their script and pictures of the plot to the VLE used in Maynooth, which is called Moodle.

In the manner of a TV chef announcing `here’s one I did earlier’, this a sample output produced by my `model’ code:

I wonder if you can guess of what function this is the derivative? By the way in this context `model’ does not mean `a standard of excellence’ but `an imitation of something’ (me being an imitation of a computational physicist). Anyway, students will get marks for producing plots that look right, but also for presenting a nice (commented!) bit of code

This afternoon I’m on Cardiff time but I was able to keep an eye on the submissions coming in to Moodle in case something went wrong. It seemed to work out OK, but the main problem now is that I’ve got 20-odd bits of code to mark! That will have to wait until I’m properly on Maynooth time!

Now, back to the grind…

The de Valera connection

Posted in History, mathematics, Maynooth with tags , , on February 14, 2018 by telescoper

This morning I took the early flight to Dublin, which was on time, and thence via the Airport Hopper to Maynooth. There were only two passengers on the bus, both going to the terminus, so it made good time, travelling all the way along the motorway.

Walking into the Maynooth campus I remembered an interesting little historical fact that I stumbled across last week, concerning Éamon de Valera, founder of Fianna Fáil (one of the two largest political parties in Ireland) and architect of the Irish constitution. 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. He subsequently became Taoiseach (Prime Minister) and then President (Head of State) of the Irish Republic.

The point of connection with Maynooth, however, is less about Dev’s political career than his educational background: he 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. It is said that one of the spare gowns available to be borrowed by staff for graduation ceremonies belonged to de Valera. Mathematical Physics is no longer a part of the Mathematics Department at Maynooth, having become a Department in its own right and it recently changed its name to the Department of Theoretical 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?

That’s one connection, but when I arrived in the office this morning I found another. An email had arrived announcing a conference later this year in honour of Erwin Schrödinger.  It was de Valera – a notable advocate for science – who in 1940 set up the Dublin Institute for Advanced Studies (DIAS); Schrödinger became the first Director of the School of Theoretical Physics, one of the three Schools in DIAS.

Lunch with Pugin

Posted in Architecture, Maynooth with tags , , , on February 9, 2018 by telescoper

I usually have a sandwich lunch when I’m in Maynooth because I’m quite busy, but it’s rather cold (though bright) today so I decided to get myself a hot lunch at Pugin Hall, which is situated in St Patrick’s House on the South Campus of Maynooth University. I stayed in St Patrick’s House briefly before Christmas, and had my breakfasts in Pugin Hall. It’s a nice place to have an expensive but filling meal. It was particularly cosy today because of the sunlight streaming in through the windows:

The hall is named, of course, in honour of architect Augustus Pugin. He didn’t design St Patrick’s House itself – construction of that building started before he was born – but did lay out the quadrangles elsewhere that make up much of the South Campus.

The Quickening of the Year

Posted in Education, Maynooth, Music, The Universe and Stuff with tags , , , , on February 1, 2018 by telescoper

It’s 1st February 2018, which means that today is Imbolc, a Gaelic festival marking the point halfway between the winter solstice and vernal equinox. This either happens 1st or 2nd February, and this year it is the former. In this part of the world – I’m in Ireland as I write- this day is sometimes regarded as the first day of spring, as it is roughly the time when the first spring lambs are born. It corresponds to the Welsh Gŵyl Fair y Canhwyllau and is also known as the `Cross Quarter Day’ or (my favourite) `The Quickening of the Year’.

So, talking of quickening, the pace of things is increasing for me now too. This morning at 9am I gave my first ever lecture in Maynooth University in a lecture theatre called Physics Hall, which is in the old (South) part of campus as opposed to the newer North Campus where the Science Building that contains my office is situated.

After that it was back to the Department for some frantic behind-the-scenes activity setting up accounts for the students for the afternoon lab session, which is in a computer room near to my office. Students attend one two-hour lab session in addition to the lecture, on either Thursday or Tuesday. The first lecture being this morning (Thursday) the first lab session was this afternoon, with the same material being covered next Tuesday.

I was far more nervous about this afternoon’s lab session than I was about this morning’s lecture as there seemed to be many things that could go wrong in getting the students up and running on our Linux cluster and getting them started on Python. Quite a few things did go wrong, in fact, but they were fewer in number and less drastic in outcome that I had feared.

So there we are, my first full day teaching in Maynooth. I think it went reasonably well and it was certainly nice to meet my first group of Maynooth students who, being physics students, are definitely la crème de la crème. I’ve got another 6 weeks like this (teaching on Tuesday in Cardiff and on Thursday in Maynooth) before the Easter break so it’s going to be a hectic period. Just for tonight, however, I’ve got time to relax with a glass or several of wine.

Incidentally, I was impressed that Physics Hall (where I did this morning’s lecture) is equipped with an electric piano:

I wonder if anyone can suggest appropriate musical numbers to perform for a class of computational physicists? Suggestions are hereby invited via the Comments Box!

The Future is Unpredictable

Posted in Biographical, Cardiff, Maynooth with tags , , on January 31, 2018 by telescoper

I decided to take the early morning flight from Cardiff to Dublin today as I have quite a few things to prepare before my first lecture at Maynooth, which is at 9am. I actually got up at 4am and took the 5.10am bus to the airport so that I would arrive in time to have a coffee and a bacon sandwich before the 6.55am flight. Everything went to plan apart from the inclement weather, which resulted in me getting soaked on the way to the bus stop. The plane struggled against a strong headwind, taking 70 minutes to get to Dublin instead of the usual 40, and there was quite a lot of turbulence en route but we arrived on time in Dublin in time for my bus to Maynooth. It was freezing cold this morning, and as I arrived in Maynooth it started snowing but has now stopped.

While waiting in the airport I checked Facebook, which reminded me that it was exactly five years ago today that I left Cardiff to take up the job of Head of Mathematical and Physical Sciences at the University of Sussex. One of my last acts was to sign the work of art I left on the whiteboard in my old office.

The initial term of my appointment at the University of Sussex was 5 years, which would have been finishing today had I stayed there. If somebody had told me then that within five years I would have left Sussex, returned to Cardiff temporarily, and be about to move permanently to Ireland it would have seemed most implausible. More importantly, way back then I had no plans to grow a beard!

It just goes to show that Niels Bohr was right when he stated that `Prediction is very difficult, especially about the future’….

..on the other hand, when I got back to Maynooth I found that my new Public Services Card had arrived, which seems to make a definite prediction of the date of my ultimate demise:

University Pension Differences

Posted in Education, Finance, Maynooth with tags , , , , , , , , on January 26, 2018 by telescoper

Following a ballot of members of the University and College Union (UCU), the UK university sector is gearing up for strike action over proposed changes to the USS pension scheme. Unless the dispute is resolved in the meantime (which I think is highly unlikely) the first strike lasting two days will place on 22nd and 23rd February. Thereafter strikes will escalate to cover three days, four days and five days in subsequent weeks.  I’ll actually be in Maynooth for the first 48 hour block so won’t have to worry about crossing a picket line initially, but will have to later if it drags on. It looks set to be a bitter dispute which will not be easily resolved.

When I joined USS (in 1988) it was a simple `Final Salary Scheme’. Both employer and employee contributed and the benefits accrued were an index-linked pension of 1/80 of the final salary for each year of contributions and a (tax-free) lump sum of 3/80 for each year of contributions. I joined at age 25 so I expected to accrue 40 years of pension if I retired at 65, namely a pension of half my final year’s salary and a lump sum of three-halves. It looked a good deal and was a significant factor mitigating the relatively low starting salary for academics in those days.

Over the years it became apparent that this scheme is actuarially unsound because (a) people are living longer, increasing the scheme’s liability and (b) investment growth achieved by the USS fund managers has decreased, with a negative impact on asset growth. Moreover, the USS fund is not underwritten by the government, so if it collapses completely members could be left with no benefits at all.

The USS Final Salary scheme was closed to new entrants some years ago and replaced by a less generous defined benefit scheme. A couple of years ago it was closed to existing members too, though the benefits accrued are retained; I will now only be able to get 28/80 of my final salary from that scheme when I actually retire. The scheme was replaced by a hybrid of an even less generous defined benefit scheme and a defined contribution scheme (where the pension benefit is dependent on the fund valuation at retirement, as most private pensions). Now the proposal is to remove the defined benefit component entirely. The loss of pension benefits will be substantial.

I don’t see any easy settlement of this dispute so I’m glad that it won’t affect me very much. I’ll be leaving the UK Higher Education system this summer and relocating to Ireland. Quite a few people have asked me how the pension scheme works here so I thought I’d point out the differences.

The first thing to say is as a professor in the National University of Ireland at Maynooth I am treated as a public servant so my future pension benefits here are covered by the Single Public Service Pension scheme. This resembles the final salary scheme that USS used to be, but with the important difference is that it is integrated with the State Pension to which everyone is entitled if they pay social insurance contributions. This – called the SPC – is similar to the old State Earnings-Related Pension Scheme (SERPS). Since public employees benefit from this as well as the public service pension scheme, the accrual rate in the latter is lower than the old USS scheme – just 0.58% per year – on salaries up to €45,000. For salaries above this figure the amount above the  limit generates an accrual rate 0f 1/80, just as the USS version. There is also a lump sum which accrues at 3.75% per annum, the same as the USS scheme.

In summary, then, the big difference is that in Ireland the public service pension is integrated with the state pension, whereas in the UK the latter is entirely separate. It’s also the case that in Ireland the pension is guaranteed by the government (which, of course, can change the rules…)

In my opinion the pension scheme for University staff in Ireland is significantly better value than the diminishing returns provided by the USS scheme, yet another reason why I made the decision to move here.

 

Maynooth joins the Euclid Community

Posted in Euclid, Maynooth, The Universe and Stuff with tags , , , on January 10, 2018 by telescoper

There’s a nice webpage showing all the institutions around the world who belong to the consortium behind the European Space Agency’s Euclid Mission. Here’s a screen grab that shows all the logos of all the institutions involved in this very large Consortium:

There are so many that it’s hard to see them all, but if you look very closely about half way down, among the Ms, you will see Maynooth University among them. This is the first institution in Ireland to have joined the Euclid Consortium and it has just been officially added thanks to yours truly moving there later this year. Ireland is a member state of the European Space Agency, by the way.
