It seems the weather is about to turn cooler and we may even have some rain this evening. I won’t be sorry at either of those eventualities as I’m not really cut out for the heat, and my garden could do with a bit of water on it.
This honeysuckle is looking the worse for wear but has actually been flowering for several weeks already while still keeping its lovely fragrance. The bees like it too!
While I was out these started to flower. There’s a couple of different types of Montbretia in there:
I remember they were in flower last summer when I visited the house with a view to buying it. Was that really a year ago?
This Hydrangea also flowered while I was away. I don’t think it will last much longer so I almost missed it.
The dryness has probably made it difficult for the birds as well as the plants. A few weeks ago I found a dead blackbird on my garden table. It was just a youngster; there wasn’t a mark on it. I’m not sure why it died but it’s tough being a blackbird. They are born in several broods each year and only live a couple of weeks in the nest before being turfed out to fend for themselves. They like damp conditions and feed on worms and the like, so it’s difficult for them when it’s very dry. I guess sometimes they just don’t adapt quickly enough.
There is no shortage of live birds in the garden; there are plenty of bugs, berries and other things to eat. The dawn chorus is still rather loud but I think they tend to stay in the shade during the day. The one bird that seems to be out and about all the time is the robin.
So last night I returned safely from Cardiff to Ireland via Birmingham. Travel both ways was relatively uneventful. There can’t have been more than 30 people on the flight in either direction. I did however almost screw up the return flight by omitting to fill in the obligatory Covid-19 passenger locator form which I hadn’t realised is now online-only. I only found out that I had to do it before they would let me on the plane, resulting in a mad scramble with a poor phone connection to get it done. After a few goes and quite a bit of stress I succeeded and was allowed to board, conspicuously the last passenger to do so. We still managed to leave early though, and the short flight to Dublin – passing directly over Ynys Môn was relaxing and arrived on schedule; the immigration officer scanned my new-fangled Covid-19 vaccination certificate but wasn’t interested in the passenger locator form that caused me so much stress on departure.
I returned to Cardiff to take a bit of a break, to check up on my house and also prepare to move the rest of my belongings to Ireland. I was relieved when I got there last week that everything was basically in order, although there were lots of cobwebs and a very musty smell, which was hardly surprising since I hadn’t been there for 15 months. The inside of the fridge wasn’t a pretty sight either.
One night last week after meeting some friends for a beer in Cardiff I walked back via Pontcanna Fields and saw, much to my surprise, Camogie practice in progress in the twilight:
Camogie Practice, Pontcanna Fields, Cardiff.
The logistics of my planned removal proved a bit more complicated than I expected but eventually I cracked it and all the arrangements are now in place. I should receive delivery here in Maynooth next month. I’m doing it on the cheap as a part-load, which is why it will take a bit longer than usual.
Cleaning and packing was very hard work owing to the intense heat over the last week or so – it was regularly over 30° C – during the day, so I took quite a few siestas. My neighbours tell me it’s been much the same here in Maynooth, although it is a bit cooler today, around 20° with a very pleasant breeze.
Despite the hard work it was nice to have a change of scenery for a bit and also to meet up with some old friends from Cardiff days. Everyone has been in a state of limbo for the last 18 months or so, and although we’re not out of the woods yet there are signs of things coming back to life. When I went to Bubs in Cardiff for a drink last week it was the first time I’d been inside a pub since February 2020!
Incidentally, most people I saw observed social distancing, wore masks, etc. The rules in Wales are still fairly strict. Although open for indoor service, bars and restaurants seem to have few customers. Some people on trains to and from Birmingham didn’t wear masks. One group of unmasked and obnoxious English passengers on my return journey were loudly boasting how backwards Wales was compared to England, where the rules have relaxed despite a huge surge in cases. I moved to another carriage.
The only other thing I managed to do was attend a Royal London One-Day Cup match at Sophia Gardens between Glamorgan and Warwickshire in the baking heat of Sophia Gardens. It turned out to be a good tight game, with Glamorgan winning by 2 wickets courtesy of two consecutive boundaries. Most of the time I was sitting there in the shade I was thinking how glad I was not to be fielding in such conditions.
One thing that was very noticeable during my stay in Wales was that it was very hard to get fresh salad vegetables and the like. That may be partly due to weather-related demand or it may be due to a shortage of lorry drivers or other staff owing to Covid-19 isolation requirements and may be a consequence of Brexit. Who knows? I’ll just say that there’s been hot weather in Ireland, where the Covid-19 pandemic is also happening but there are no reports of shortages of fresh food here. I’m very much looking forward to having a nice salad with my dinner this evening.
Anyway, I suppose that’s enough rambling. At some point I’ll have to open up my email box to see what horrors lurk therein. Still can’t be worse than the fridge I opened last week. Can it?
Just a quick post to pass on the news that there are a couple of new funding programmes run by the Irish Research Council. The full description of these programmes can be found here, but here is an excerpt:
The Council is inviting applications at the early and mid-career level (Starting and Consolidator). Funding will be awarded on the basis solely of excellence, assessed through a rigorous and independent international peer-review process. Laureates will enhance their track record and international competitiveness. As well as the benefits for the laureate and their team, it is anticipated that the award will enhance the potential for subsequent ERC success as a further career milestone; indeed it will be a requirement of all laureates that they make a follow-on application to the ERC.
Fortunately the remit of the IRC is broader than Science Foundation Ireland, which has a narrow focus on research likely to lead to short-term returns, so it is more likely to appeal to those working in more speculative fundamental or frontier science, including Astrophysics. Unfortunately IRC has a lot less money than SFI.
An overview of the programme can be found in the following recording of a webinar that took place last week:
The way the call works is that you must first lodge an Expression of Interest with the institution to which you wish to apply, i.e. Maynooth University. That must be done by 27th August 2021. Full applications will then be due in November.
I came across the above painting on the Maynooth local history Facebook page the other day and thought I’d share it here. It’s by a fairly obscure artist called Willem van der Hagen who was Dutch but who settled in Ireland around 1720. The painting (oil on canvas, 107.6 cm by 133.6 cm) dates from around 1730 and was sold at Christie’s in 2017 for £428,750. The painting was probably commissioned by Henry Ingoldsby who inherited Carton Demesne on the death of his father Sir Richard Ingoldsby in 1712.
The view is of Carton House, a location very close to where I live and which I blogged about here. The grounds of Carton House are very pleasant for taking recreational walks.
The bird’s-eye view in the painting shows Carton and its demesne before the house was extensively remodelled in the mid-18th Century, although the layout is still recognizable in the modern house:
Th refurbishment of the house was undertaken by architect Richard Castle for the 19th Earl of Kildare between 1739 and 1745. The view in the painting dates from before this change and shows Carton at the centre of an elaborate formal garden. In the foreground, on the southern side of the house, avenues of lime trees radiate outward into the countryside from the enclosed entrance courtyard; on the northern side of the house can be seen a stepped series of walled gardens and terraced walks.
The gardens and demesne were also transformed when the house was rebuilt to reflect mid eighteenth-century taste. More recently the grounds have been turned into golf courses, one to the front and one to the rear as the house itself is now a golfing resort hotel so nothing remains of these extensive gardens.
In the distance to the far left you can see the ruins of the keep of the ancient FitzGerald castle in Maynooth, but St Patrick’s College was not built until the end of the 18th Century and much of the present-day town centre dates from the 19th Century so in those days Maynooth was a small place. The area between the castle and the walls surrounding Carton House demesne is now largely built-up although there is a pleasant tree-lined avenue leading from Maynooth towards the House as far as the Dunboyne Road.
In the right foreground you can see the Prospect Tower built by the Earl of Tyrconnell, which still stands. I always assumed this was some sort of folly but it was apparently intended as a mausoleum for one of the previous owners of the house.
I was planning to be on leave now; I intended to make up for the fact that I didn’t get a summer holiday last year by taking most of July off. Unfortunately that was not to be and I have to stay at work for at least another week to participate in an interview panel. I may still get a couple of weeks after that but if I do it will be taken up with organizing the move of the rest of my belongings from Cardiff to Maynooth, rather than being an actual holiday.
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.
I was appointed as Head of Department for three years, but last week I asked the University to let me step down from my role as Head of Department of Theoretical Physics from the end of September 2021, a year early. I’ll carry on as a Professor, hopefully with some time to do research, although my teaching duties will undoubtedly remain heavy.
At least now, if I do get some holiday this summer I’ll be spared some of the dread of what I’ll have to return to afterwards…
*For those who are wondering, two of those modules are 36 lectures (3 per week for a 12-week semester), two are 24 lectures (two per week for a semester) and one is computer-based (1 lecture + a 2hr lab session per week for a semester). That load is about average for full-time staff in the Department; if I did less someone else would have to do more.
UPDATE: 6th July. The University has agreed to my request. “Freedom Day” for me is October 1st 2021.
Yesterday the Chair of the National Public Health Emergency Team (NPHET), who also happens to be the President of Maynooth University, Professor Philip Nolan published a lengthy but interesting Twitter thread (which you can find unrolled here). In these tweets he explained the reason behind NPHET’s recommendation to pause the process of relaxing Covid-19 restrictions, postponing the next phase which was due to begin on 5th July with indoor dining.
The basic reason for this is obvious. When restrictions were lifted last summer the reproduction number increased to a value in the range 1.4 to 1.6 but the infection rate was then just a handful per day (on July 1st 2020 the number of new cases reported was 6). Now the figures are orders of magnitude higher (yesterday saw 452 new cases). A period of exponential growth starting from such a high base would be catastrophic. It was bad enough last year starting from much lower levels and the Delta variant currently in circulation is more transmissable. Vaccination obviously helps, but only about 40% of the Irish population is fully immunized.
Incidentally the target earlier this year was that 82% of the adult population should have received one jab. We are missing detailed numbers because of the recent ransomware attack on the HSE system, but it is clear that number has been missed by a considerable margin. The correct figure is more like 67%. Moreover, one dose does not provide adequate protection against the Delta variant so we’re really not in a good position this summer. In fact I think there’s a strong possibility that we’ll be starting the 2021/22 academic year in worse shape than we did last year.
In general think the Government’s decision was entirely reasonable, though it obviously didn’t go down well with the hospitality sector and others. What does not seem reasonable to me is the suggestion that restaurants should be open for indoor dining only for people who are fully vaccinated. This would not only be very difficult to police, but also ignores the fact that the vast majority of people serving food in such environments would not be vaccinated and are therefore at high risk.
As things stand, I think it highly unlikely that campuses will be open in September. Rapidly growing pockets of Delta variant have already been seeded in Ireland (and elsewhere in Europe). It seems much more likely to me that September will see us yet again in a hard lockdown with all teaching online.
But the main reason for writing this post is that the thread I mentioned above includes a link to a paper on the arXiv (by Gleeson et al.) that describes the model used to describe the pandemic here in Ireland. Here is the abstract:
We describe the population-based SEIR (susceptible, exposed, infected, removed) model developed by the Irish Epidemiological Modelling Advisory Group (IEMAG), which advises the Irish government on COVID-19 responses. The model assumes a time-varying effective contact rate (equivalently, a time-varying reproduction number) to model the effect of non-pharmaceutical interventions. A crucial technical challenge in applying such models is their accurate calibration to observed data, e.g., to the daily number of confirmed new cases, as the past history of the disease strongly affects predictions of future scenarios. We demonstrate an approach based on inversion of the SEIR equations in conjunction with statistical modelling and spline-fitting of the data, to produce a robust methodology for calibration of a wide class of models of this type.
This model is a more complicated variation of the standard compartment-based models described here. Here’s a schematic of the structure:
This model that makes a number of simplifying assumptions but it does capture the main features of the growth of the pandemic reasonably well.
Coincidentally I set a Computational Physics project this year that involved developing a Python code that does numerical solutions of this model. It’s not physics of course, but the network of equations is similar to what you mind find in physical systems – it’s basically just a set of coupled ODEs- and I thought it would be interesting because it was topical. The main point is that if you study Theoretical Physics you can apply the knowledge and skills you obtain in a huge range of fields and disciplines. Developing the model does of course require domain-specific epidemiological knowledge but the general task of modelling complex time-evolving systems is definitely something physicists should be adept at doing. Transferable skills is the name of the game!
I’ve just finished my presentation about Theoretical Physics at today’s Open Day in Maynooth and now have a short break before the online Question-and-Answer session so I thought I’d use the time to do a quick post.
Yesterday our students got their marks and as a consequence I had quite a few emails from students about their results. Happily the vast majority were absolutely lovely. Here are two excerpts of emails from graduating students (I’ve removed bits to ensure anonymity):
Thanks a million for all your support throughout the 3 years. I enjoyed every minute of this course, largely due to yourself and the other lecturers..
Thank you and everyone in the TP department for everything, I am indebted to you all and am incredibly gratefully for all your support, help and advice.
And another:
I want to express my gratitude to yourself and the rest of the department. I had a great experience in Maynooth and having personable and helpful professors helped a lot.
Such nice comments mean a very great deal, especially since these students – and others too numerous to mention – have been taught remotely for the last three semesters. They’re not just about me, of course; they refer to all the staff in the Department. I’m sure the gratitude expressed goes both ways too. I’d like to take this opportunity to thank all our students for putting up with everything that’s been thrown at them over the last year and a half and for being so determined and cooperative.
I really do hope it will be possible to offer congratulations in person to our graduating class at a formal Conferring Ceremony due to take place in September, but that I suppose is dependent on the progress of the Covid-19 pandemic, vaccination, and so on. It’s out of my hands.
I’ve said before on this blog that I always feel a curious sense of loss at the end of an academic year. After three or four years in the Department you’re only just starting to get to know students and then suddenly they’re finished. This year in particular it would be very sad if they just disappeared without a proper goodbye. As one of my correspondents said:
I am really looking forward to attending the conferring ceremony. As you said, it’s been far too long since we’ve talked to anyone in the department in person.
Of course this little tinge of sadness is more than made up by the success of these students which is hard won and thoroughly well deserved. I’m very pleased for them all. They now have the opportunity to follow a career of their choice. It must be very exciting for them, as a degree in Theoretical Physics opens a great many doors!
Yesterday was quite a busy day because, as well as my talk in the afternoon, we had the main University Examination Board in the morning. Because many students in Maynooth are taking courses that spread across more than one Department, this is an opportunity to raise any issues arising when marks are combined. The full results for each student are presented on “Broadsheets” which I suspect in days gone by would have been broad sheets of paper, but which nowadays are hefty PDF files, one for each faculty. Science & Engineering was the first session, kicking off at 9.15 via Teams but because we all had access to the Broadsheets since last Friday we had time to identify any relevant matters and the meeting itself went quite smoothly.
Now there’s a short hiatus because the formal results will not be communicated to students until tomorrow (Friday 25th). Next Tuesday (29th June) is Consultation Day, on which students can discuss their results and any matters arising with staff. Obviously we can’t do this in person this year because of Covid-19 restrictions but, because the examination scripts were scanned and uploaded electronically this year the students will actually have the originals, discussing any issues of marking shouldn’t be too difficult.
Some students will need to take repeat examinations before they can progress. These are in the period 4th-14th August in Maynooth so I’ll have to be around for those. I was hoping to try to get some summer holiday this year – which I didn’t last summer – starting on 5th July, but that has already been pushed back because something important has arisen that means I have to be working on 7th July. I hope nothing else eats into my leave entitlement. It says in my contract how many weeks holiday I should have per year so I will not accept another year of not being able to take it.
Although we have a short break in the examination process that doesn’t mean everything stops. I have to work this Saturday (26th June) at the Summer Open Day here at Maynooth, recruiting the September intake…
The sense of hiatus is amplified by the fact that there are no matches today or tomorrow in the European Championship, the final group games being last night and the first in the Round of 16 being on Saturday. I’ve got quite used to watching the 8pm matches over the last couple of weeks!
The Royal Canal, Maynooth (Picture Credit: M. Maher)
Written in 1954 when the poet was recovering from a life-threatening illness this poem – a sonnet by Patrick Kavanagh – is a celebration not only of nature’s powers of regeneration but of the delight in taking things slowly. As he expressed in his lecture Man and Poet:
We are in too great a hurry. We want a person or thing to yield their pleasures and their secrets to us quickly for we have other commitments. But it is the days when we are idle, when nothing appears to be happening, which provide us, when no one is looking, with all that is memorable.
Here is the poem Canal Bank Walk:
Leafy-with-love banks and the green waters of the canal Pouring redemption for me, that I do The will of God, wallow in the habitual, the banal, Grow with nature again as before I grew. The bright stick trapped, the breeze adding a third Party to the couple kissing on an old seat, And a bird gathering materials for the nest for the Word Eloquently new and abandoned to its delirious beat. O unworn world enrapture me, encapture me in a web Of fabulous grass and eternal voices by a beech, Feed the gaping need of my senses, give me ad lib To pray unselfconsciously with overflowing speech For this soul needs to be honoured with a new dress woven From green and blue things and arguments that cannot be proven.
The Irish Government has just produced its plan for A Safe Return to on-site further and higher education and research that outlines what is basically a full return to on-campus activity from September 2021.
I quote from the preamble to the document linked to above:
It is expected that the majority of the people over 18 in Ireland will have been vaccinated by September 2021, and so planning is proceeding on the basis that full resumption of on-site activity is possible, while ensuring that overall numbers attending on-site are monitored and controlled.
In the absence of regular updates about the progress of Ireland’s vaccination programme it is difficult to know whether the first sentence is accurate or not, especially since it appears that two vaccine doses are needed to protect against the Delta-variant. I think most teaching staff will have been immunized by September, but am not so sure about the student population.
I’m also mindful that we were optimistic in advance of the start of last academic year and things didn’t exactly go to plan then. Nevertheless there do seem to be reasonable grounds for believing that we can return to on-campus teaching in September and we will be planning on that basis until there is evidence to the contrary. I just hope we don’t have to do a rapid about-turn like we did last year.
The first step in this process for us here in Maynooth is that from 5th July staff and research students can return to their offices on campus – following the existing protocols on social distancing, sanitation and ventilation – without having to make a special case. Only a few people have been working inside the Department since the start of the year and I’d expect most to begin making their way back.
In fact some members of the Department of Theoretical Physics joined us only this academic year and have never actually been the building (or on campus) at all. I suppose I’ll now have to find office space for them, something that hasn’t been necessary while we have all been working from home!
As a matter of fact, since it’s a nice day and I’ve been on Teams all morning, I might take a walk onto campus myself this afternoon and visit my office in the Department for the first time in a month…
