Before Phase Three..

Posted in Biographical, Covid-19, Maynooth with tags , , on June 28, 2020 by telescoper

Tomorrow (on Monday 29th June) Ireland will enter Phase Three of its (accelerated) Roadmap for Reopening after the Covid-19 restrictions.

The Coronavirus situation here remains relatively stable, with new cases steady at a low level:

This is not the case for the rest of the world, however. Yesterday two grim milestones were passed: 10,000,000 confirmed cases of Covid-19 worldwide and 500,000 deaths:

Much of the recent numerical growth of the pandemic is associated with North and South America. Brazil is particularly badly affected as are some of the United States. I don’t need to comment on the quality of the political leadership involved.

I am very nervous about the situation in the United Kingdom too, where I feel the reopening is being rushed. Poor leadership is partly responsible for the continuing high levels of infection there too.

Anyway, back to Phase Three in Ireland. Yesterday I bought a copy of the Irish Times and found this booklet inside:

The emphasis is on the fact that despite the low levels in Ireland Covid-19 has not gone away and we all have to be prepared to take special precautions for the foreseeable future. I would be amazed if there wasn’t another flare-up here at some point, actually, it’s just a question of when. And those optimistic about the delivery of a vaccine in the near future, I’ll remind you that there isn’t yet a vaccine for any form of Coronavirus let alone the novel form responsible for Covid-19 (SARS-CoV-2).

Anyway, on Friday I attended a virtual Question and Answer session with the President of Maynooth University, Professor Philip Nolan, about the plans for reopening campus over the Summer and into the new academic year. It is clear that lots will have to be done before staff can return fully and even then it won’t be anything like “normal”.

Incidentally the issue of face masks came up and there was some discussion about their effectiveness. Not being a medical expert I don’t really know about that, but I think one of the important things about masks in a work environment is that their visibility means that they work as a signal to remind people to be aware of Covid-19. I have discarded my home-made face masks and bought a box of proper ones and I intend to wear them whenever I am in a work setting in which anyone else is present.

On Friday evening I finally received (relatively) detailed instructions on how the return to work process will work. The Department of Theoretical Physics at Maynooth University is still basically in Phase 1 while the university working group has been assembling this guidance. It will probably be several more weeks before we can get people back to work because there are many things still to be done: including the installation of hand sanitizers, one-way systems, screens, and new signage.

Another thing that came up during the President’s Q&A was the question of vacations for staff. Fortunately I had muted both my audio and video feeds for this as I laughed out loud. What with organising the return to work, overseeing repeat exams, recruiting a sabbatical replacement, planning teaching for next year, rewriting my own lectures for the “new normal”, etc etc, and (hopefully) moving into a new house, I can’t see any prospect of any summer holiday this year at all!

Scrambled Phases

Posted in Biographical, Covid-19, Maynooth with tags , , , on June 22, 2020 by telescoper

A couple of weeks ago I posted about the imminent start of Phase 2 of the Irish Government’s Roadmap for Reopening after the closures enforced because of the Covid-19 pandemic.

Since then the Irish Government has decided that there will only be four phases instead of five, and many elements of the programme will be moved forward. For example, all travel restrictions within the Republic will be lifted from next Monday (29th June), which is when Phase 3 is due to commence. It has also been announced that hairdressers, barbers, nail and brow salons, beauty salons, spas, make-up application services, tanning, tattooing and piercing services will re-open. I find that surprising, as I find it hard to see how such services can be provided at low risk of transmitting Covid-19.

In fact I find the whole idea of accelerating the Roadmap rather worrying. I hope I’m proved wrong, but it seems to me that the Government is rushing this. There are worrying signs in Germany that the R-number is increasing significantly and undue haste in opening business may lead to a similar rise. It must be stressed that the number of cases involved in Germany  is rather small and most are confined in local outbreaks that can be contained. Nevertheless, this remains a concern.

At the moment the situation looks stable, with new cases at a very low level:

I do worry however that, since only a very small fraction of the population (at most a few percent) have been infected with Covid-19, there will be very little resistance if Covid-19 starts to spread again.

As for my own work situation here at Maynooth University, what happens in Phases Three and Four is all a bit hypothetical, because we’re still stuck in Phase One! The University management is being extremely cautious about allowing anyone back to work at all until various protocols are agreed, risk assessments carried out, and staff training delivered. It seems likely therefore that we will reach Monday’s scheduled start of Phase 3 before we are even ready for Phase 2. In practice, therefore, the various phases of the Roadmap are no longer relevant in this particular setting. I think I’ll remain the only person coming in to the Department for quite some time!

I fully understand and support the careful approach adopted  by the University, of course, and the delay doesn’t matter that much as our teaching semester is now finished and, being theorists, we can all work from  home reasonably effectively. It must be more of a challenge for laboratory-based researchers. My main concern is  I’d be very surprised if all the other organizations and businesses due to open next Monday are as cautious. The last thing we need for people to cut corners and send us all back to square one.

Psychological Time

Posted in Biographical, Covid-19, Education with tags , , , on June 21, 2020 by telescoper

So, the Summer Solstice for 2020 is now in the past. It’s all downhill from here!

As the Solstice approached last night I was thinking back to the Vernal Equinox which had happened this year on March 20th, exactly three months before. That was at the end of Study Week in the Spring Semester but the students did not return the following week and we switched to remote teaching. I find it astonishing to think that was just three months ago. It seems like ancient history. Not only that but several major events took place during that period that I find it hard place in chronological order without looking at written records (including this blog).

I am not an expert on such matters but it seems to me that the isolation, disruption of social interaction, and the loss of familiar routines imposed by work are among the things responsible distorting perception of the passage of time. I have tried to impose a regular pattern on my day during this time but only with limited success. I suspect it’s not only me who has felt like this over the past weeks and months!

It’s not just the disruption to routine of course. There was also a genuine fear of becoming infected. My last in-person lecture was on 12th March, the Thursday before Study Week. From time to time I wondered if I would ever see those students again. I also made arrangements to write a will. For a time it looked likely that intensive care facilities in Ireland might be overwhelmed so I felt it important to make contingencies of that sort. Fortunately they weren’t needed. As far as I know the Coronavirus hasn’t reached me. I certainly haven’t had any symptoms, though I haven’t actually been tested.

Overall I found the lockdown very difficult at first but I think adjusted reasonably well despite (or perhaps because of?) having very peculiar dreams.

Now that the Covid-19 restrictions are gradually being wound down hopefully some measure of routine will resume and the sense of disorientation will fade. Time will tell.

Marking Time

Posted in Covid-19, Education, Maynooth with tags , , on June 12, 2020 by telescoper

In among all the other things I have to do I’ve just finished marking my portion of examinations and other assessments in time for next week’s Examination Boards. I have to attend two (virtually), one for Theoretical Physics and one for Engineering Mathematics. You may recall that, this year, along with many other universities, we switched from the usual examination format to online timed assessments.

Obviously I can’t talk about any actual results here but I can relay a few general points.

First, there were remarkably few hitches in the examination process. I would like to say that I was totally confident that the new system would work, but I’m afraid I was very nervous during the examination period. I’m glad that I was proved wrong. That’s not only due to very hard work by the teaching staff in getting everything together to go online and the technical support staff for ensuring the submission portals could handle the load, but also due to the students who coped admirably well with the new assessment style.

That said, I think if we are going to have such assessments again in the future there are things we could improve.In particular the mathematical nature of our work means that students have to do their working, diagrams etc by hand and sometimes the quality of scanning made the resulting submissions very difficult to read. If we had had time we could have offered more training to the students on how to scan their work more legibly, so next time we will probably do that too. Indeed we will probably be doing most of the coursework that way next term so they will probably get more practice anyway.

Printing the work out usually made the legibility problem worse, so I generally marked as much as I could on the screen. We don’t have very good software for doing this in bulk so it was painfully slow. I estimate it took me about three times as long to mark an examination script this way than doing it on paper. I’d be very interesting to hear via the comments box of any suggestions or recommendations of software to help this process!

The main purpose of this post however is to say a very public thank you to all the teaching staff in the Department of Theoretical Physics and to our admirable Departmental Administrator Suzie  for working so hard in difficult circumstances to get everything done in time!

Time for Phase 2 in Ireland

Posted in Covid-19, Maynooth with tags , , on June 7, 2020 by telescoper

Tomorrow (June 8th) sees the start of Phase 2 of Ireland’s Roadmap for Reopening. You can see that, as of yesterday, the number of confirmed cases per day is small and stable after three weeks of Phase 1, which has justified proceeding to Phase 2.

Incidentally, since the Covid-19 outbreak took hold in Ireland there have been daily press briefings by the Department of Health. Yesterday’s was the last of these: from now on the updates will be twice a week, on Mondays and Thursdays. Data will still be released every day but there won’t be a press conference every time. I’ve been following these every day for three months so this will be quite a change to the routine!

Moving to Phase 2 means that most shops will be able to reopen (subject to social distancing measures being in place), people will be able to travel much further (anywhere within your own county and 20 km into another) and there will be a limited return to work (subject to the completion of various protocols, risk assessments, etc).

For us at Maynooth University there won’t be a sudden change. Staff who can will continue to work from home (which is basically everyone in the Department of Theoretical Physics) but labs will gradually reopen for research when the necessary arrangements are in place. Other than that Phase 2 will be very similar to Phase 1.

On Friday, however, the Taioseach announced that the Roadmap would be accelerated so that Phase 4, starting 20th July will, if all goes well, be the last, though measures will be in place for some time after that.

That’s good news of course but it’s all dependent on there being no second wave. As a cautionary tale, take a look at the numbers for Covid-19 Iran:

Iran has been experiencing a second wave of new cases for some time now, and this looks set to produce more cases than the first, but this has only recently resulted in an increase in daily mortality figures:

Note the lowest number of new cases per day in Iran was just under 1000. That’s far fewer than the United Kingdom, which has chosen to undo its restrictions far more rapidly in Ireland. The number of confirmed new cases in Ireland reported yesterday was just 24; in the United Kingdom the figure was 1557. In my opinion there is a strong possibility that the UK will follow a similar trajectory to Iran…

From May to September

Posted in Biographical, Covid-19, Education, Maynooth with tags , , , , , , on May 28, 2020 by telescoper

So here we are, then. The final pair of examinations online timed assessments for students in the Department of Theoretical Physics at Maynooth University have just started and the students’ submissions will come in later this afternoon. By a curious coincidence the last two comprise a 3rd Year module on Special Relativity and a 4th year module on General Relativity, both of which happen at the same time (in the reference frame of the students).

I don’t want to jinx this afternoon’s proceedings but the switch to online assessments has gone much more smoothly than I imagined it would. I’ve been keeping an eye on all of them and there have been very few problems, and those that did arise were sorted out relatively easily. I’m immensely relieved by this, as I think I’ve been more nervous during these examinations than most of the students!

After this afternoon we will have to knuckle down and get these assessments marked in time for the round of Exam Board meetings. We have been allowed an extra week to do this because grading will be a slower process than usual, especially for the kind of mathematical work we do in the Department of Theoretical Physics. We’ll have to see how it goes but I’m confident we can get the results ready by 18th June, which is the date of our (virtual) Exam Board.

After the Exam Boards we would normally be thinking of relaxing a bit for the summer, and doing a bit of research, but there’s no sign of that being possible this year.

Among the urgent things to deal with are managing the `return to work’ of staff during the various phases of the Irish Government’s Roadmap. This document does not give much detail and there are serious issues to be solved before we can even start Phase 2 (due to commence June 8th) never mind finish Phase 5 and return to some semblance of normal working.

Iontas Lecture Theatre, Maynooth University

Slightly further off, but no less urgent is the matter of how to deal with the start of the next academic year, assuming the progress of the pandemic allows this to happen at all. One of the big uncertainties is how many potential students will defer their university study until next year, which makes it difficult to predict how many students we will have to cater for.

I have to say I’m very annoyed by recent reporting of this issue in the Irish Times, which includes this:

The fact that most lectures will take place online, along with changed economic conditions facing families and inability of students to secure summer work, may make it less attractive for many students to go to college in the coming year.

The second word fact (my emphasis) is the problem, as it describes something that is not a fact at all. A lot can happen between May and September, but we are currently planning on the basis that most of our lectures in Theoretical Physics will go ahead pretty much as normal. That may in the end turn out to be impossible, e.g. if there is a second wave of infection, but at the moment it is a reasonable scenario. And even if we do have to move some or all lectures online we will still have face-to-face teaching in the form of tutorials, exercise classes and computer laboratories.

A slightly less misleading article can be found in the same newspaper here.

A couple of weeks ago, Cambridge University announced that there would be no face-to-face lectures at all next academic year. I was amused to hear a representative of that institution on the radio sounding as if he was saying that “at Cambridge, lectures have very little to do with teaching”. I think what he meant was that tutorials and other teaching sessions would still go ahead so the loss of in-person lectures was not as important as it sounded. That may very well be true of Arts and Humanities subjects, but I was an undergraduate in Natural Sciences at Cambridge (many years ago) and I can tell you the vast majority of my tuition there was in the lecture theatre.

Neither is it the case that Oxford and Cambridge are the only UK universities to have tutorials or small group tuition, but I digress…

My point is that, while I can’t promise that it will be business as usual from September 2020, it’s quite wrong to give potential students the impression that it would be a waste of their time starting this academic year. I can assure any students reading this of the fact that we’re doing everything we can to give them as good an experience as possible.

You shouldn’t believe everything you read in the newspapers!

Anti-Malarial Memories

Posted in Biographical, Covid-19 with tags , , , , , on May 20, 2020 by telescoper

All this business about Donald Trump recommending the drug hydroxychloroquine as a treatment for Covid-19 reminded me of my first trip to India in the 1990s. I hadn’t travelled very much outside Europe before that and was quite nervous, so I bought a couple of books about travelling in India. Among other things, they both recommended taking precautions against Malaria.

I made an appointment with my GP, who asked exactly where I was going and, after consulting a book, he wrote out two prescriptions, for the drugs paludrine and chloroquine. I was to start taking them a week before travelling and continue for two weekd after returning. The paludrine came in small tablets to be taken every day; chloroquine was in a much bigger tablet taken once a week. The brand name for the latter was Avloclor. I have good reason to remember it.

The paludrine was no trouble but the chloroquine was horrible. For one thing it tasted so foul that even with a huge amount of water it was difficult to prevent unpleasant sensations as it went down. Worse, it has a long list of side effects, the mildest of which include nausea, loss of appetite, diarrhoea, upset stomach, stomach pain, rash, itching, and hair loss. More serious symptoms include heart problems, blurred vision, and suicidal thoughts. The list of warnings that came with the tablets was so long that I started to wonder how bad Malaria can be…

I’m told that anti-Malarial drugs are notoriously unpleasant, especially those given to soldiers stationed in theme tropics who presumably get the cheapest sort.

I didn’t experience any of the more serious issues, thank goodness, but I had a selection from the former list, plus a sprinkling of mouth ulcers. I knew these were caused by the chloroquine as I always got them the day after I took the tablet: they went away after a day or two but came back when I took the next week’s dose. Presumably I just couldn’t down the tablet quickly enough to avoid some of it affecting my mouth.

I was in India for about six weeks and was plagued by this for the whole time. I really enjoyed the spicy food while I was there, but found it quite difficult for a couple of days each week.

Now although chloroquine is related to hydroxychloroquine it isn’t quite the same thing. I gather, however, it does have similar side effects. As far as I’m aware there is no evidence that either of these drugs is effective against Covid-19 so in my opinion you would have to be crackers to run the risk of seriously unpleasant or even worse consequences for no therapeutic gain.

Phase 1 Approaches

Posted in Biographical, Covid-19, Education, Maynooth with tags on May 16, 2020 by telescoper

Yesterday (Friday 15th May) the Government of Ireland announced that Phase 1 of the Roadmap for relaxation of its Covid-19 restrictions would commence as planned on Monday 18th May.

This won’t make a huge difference to those people working in third level institutions because it means that anyone who can work from home should continue to do so. As you can see in the graphic above, though, some (limited) access to buildings will be available to allow staff access “to facilitate remote learning”.

Here at Maynooth University our teaching term is over and we’re into the examination period, so there is no actual teaching going on. There are exams, however, and some staff (including myself) will be going onto campus to oversee these, including sitting by their office phones in case of emergency. It is a great relief that we can do this during the examination period as things would have been far more complicated otherwise, especially for those of us who don’t have full internet access at home.

Access for this purpose will be strictly limited and in general the campus is not open. The rules for those coming into campus are quite strict. These are excerpts from the instructions sent out by the University last night:

  • Everyone who can work effectively from home should continue to do so, and non-essential travel should not be undertaken.
  • The campus is not open, and there is no general access, but you may access your office in limited circumstances if you cannot otherwise prepare for or deliver remote teaching and assessment. Approval from your Head of Department is required in all instances.
  • Always observe physical distancing of 2m and ensure thorough hand hygiene. These are key individual responsibilities to minimise the spread of the virus.
  • Employees should wash their hands when they arrive and leave.
  • Essential access will be limited to an individual’s office, provided it is not shared. If you work in a shared office, you should co-ordinate with your colleagues to make sure that you are not there at the same time.
  • There will be no general access to any shared facilities, except toilets. Toilets will be cleaned every evening, but it is the responsibility of every individual to ensure personal hand hygiene on leaving the toilets.
  • Anyone who does require access to their office should make their way directly to their office and avoid congregating in groups. Once the essential work is complete, you should leave the campus directly.

A more general ‘return-to-work’ will start in Phase 2 (in three weeks’ time) but several things related to health and safety will need to be organised before that. In the meantime I expect the Department of Theoretical Physics will continue to be empty apart from occasional visits by myself and one or two other members of staff.

Anyway, we need to take life one phase at a time. My main priority on Monday will be trying to remember where my office is, as I haven’t been there for nine weeks!

P. S. Schools in Ireland will not reopen until the start of the new school year, in August.

Dream Time

Posted in Art, Biographical, Covid-19, Mental Health with tags , , , , , , on May 13, 2020 by telescoper

The Dream (Salvador Dali, 1931)

I know I’m not alone during this strange and unsettling Coronavirus period in having extraordinarily vivid dreams almost every night.

I’m grateful for two things related to this. One is that I’m sleeping much better than usual, with not a trace of the insomnia I’ve experienced in the past during times of stress. The other is that these dreams are very far from being nightmares. Most of them are benign, and some are laugh-out-loud hilarious.

The other day, for example, I had a dream in which Nigel Farage returned from his recent trip to Dover in search of migrants publicity to find his house filled with asylum seekers singing the theme from The Dambusters. There was also a cameo appearance by Nigella Lawson in that dream but I forget the context.

I’ve written about dreams a few times before (e.g. here) and don’t intend to repeat myself here. It does seem to me however that dreams are probably a byproduct of the unconscious brain’s processing of notable recent events and this activity is heightened because the current times are filled with unfamiliar experiences.

I know some people are having far worse nocturnal experiences than me, and I don’t really understand why I’m having a relatively easy ride when my past history suggests I’d be prime candidate for cracking up. Perhaps I’ve had enough practice at dealing with anxiety in the past (not always very satisfactorily)? Perhaps the sense of detachment I’ve experienced over the past few weeks is part of some sort of defence mechanism I’ve acquired?

Anyway, don’t have nightmares!

Calculating the UK COVID Alert Level

Posted in Covid-19, mathematics, Politics with tags , , , on May 11, 2020 by telescoper

I didn’t watch yesterday’s broadcast by the UK’s Clown-in-Chief Bozo Johnson but I gather that he delivered an address that was every bit as coherent and lucid as one might have expected.

I for one am delighted that at last there is some clarity in the UK Government’s position and that they have applied the necessary level of mathematical rigour to their treatment of the Covid-19 Pandemic.

Catching up on these pronouncements via Twitter I was impressed to see, for example, to see this precise formulation of the calculation required to establish the COVID Alert Level.

Let me take you through a detailed calculation using this important formula.

As far as I know the best estimate of the basic reproduction number R in the UK is around 0.8.

As of this morning (11th May) the number of confirmed Covid-19 infections in the UK is 219,183.

Applying the formula I obtain a value

COVID Alert Level = 219183.8

That seems a big number. I thought it should only go up to 11. Have I slipped up somewhere?
