Exceptional Moods?

Posted in Biographical, Mental Health with tags , , on April 20, 2020 by telescoper

The other day I came across the following excerpt from The War Of The Worlds by H. G. Wells:

Perhaps I am a man of exceptional moods. I do not know how far my experience is common. At times I suffer from the strangest sense of detachment from myself and the world about me; I seem to watch it all from the outside, from somewhere inconceivably remote, out of time, out of space, out of the stress and tragedy of it all.

This passage struck me very forcefully because it captures what it feels like to experience depersonalisation disorder. I wrote about my own experiences of this about three years ago.

In my own case the depersonalisation was, I think, a side-effect of medication I took to deal with an anxiety condition that has plagued me off and on for many years.

In recent weeks I have often felt strangely detached in the same way as before, but I haven’t been on medication for nearly three years now so that’s not the cause this time.

Perhaps it is just the social distancing and the general stress caused by the Covid-19 outbreak that is causing it?

If so there is probably quite a number of people out there feeling the same way.do maybe these moods aren’t really exceptional?

Covid-19: the next steps

The Irish Government’s information booklet about Covid-19

Although we are currently in what is meant to be the Easter holiday the new normal continues in the form of a plethora video conferences and email exchanges punctuated by the occasional bit of rest and relaxation. We’ve even got a virtual seminar tomorrow and a virtual Open Day on Saturday 25th April to add to the fun.

One of the things making life stressful for academics these days is uncertainty about the future. Will the current lockdown actually end on May 5th? Will our plans for remote examinations work out OK? Will the Leaving Certificate actually go ahead this summer? When will the next academic year begin?

None of these issues is on the same scale as those confronting health workers and others on the front line fighting this pandemic, but that doesn’t mean they aren’t causing anxiety.

My own view is that we need to concentrate as far as possible on the next step and not get carried away by the ifs and buts about what comes after. There are too many imponderables on the horizon, so just focus on what you can control. We have three more weeks teaching here at Maynooth before the end of the Semester so let’s do that as well as we can. After that there is the exam period so let’s try to get through that with as few glitches as possible. We’ll just have to cross other bridges when we come to them.

For myself, I am sceptical that there will be any reduction of the current restrictions on May 5th and if there is, it will be slight at first. As the Taoiseach Leo Varadkar said today relaxation of the lockdown will take places gradually over a number of months. As a physicist I see the change being rather like an adiabatic process, carried out in quasi-static fashion in a series of reversible steps…

The Oldest Tree in Ireland

Posted in Biographical, History, Maynooth with tags , , , , , , on April 15, 2020 by telescoper

Regular readers of this blog – both of them – will know that I’ve developed a habit during the current lockdown of talking walks around the South Campus of Maynooth University in order to get a bit of exercise.

I’ve noticed a bit of a side effect of strolling around the environs of the old College, though, which is that I always return home sneezing. I’ve never really been susceptible to hay-fever before, but I reckon this is a reaction to tree pollen. It’s the right season for that, and there are many trees about.

Last night I was idly googling around in an attempt to identify the types of tree I would encounter on my wanderings and during the course of that I accidentally came across something fascinating.

This Yew tree stands near the main entrance to Maynooth University campus.

It’s not a particularly tall specimen and I’ve walked past it hundreds of times without paying attention to it. It is however generally believed to be the oldest tree in the Republic of Ireland (there is one tree, another Yew, possibly older, in County Fermanagh.) The tree in Maynooth germinated (or was planted) around the year 1267 ± 50, which makes it around 753 ± 50 years old.

The timing is interesting because it means that the tree is roughly the same age as Maynooth Castle and the old church. In this picture you can see the Yew tree on the left, with the church on the right and the remains of the Castle in the background:

Here’s a better picture of the Castle from another direction. Only a few bits of wall, the gatehouse and solar tower remain. The Castle was damaged and subsequently surrendered after a siege in 1535 (see below) then reoccupied only to be largely dismantled in 1647, whereafter it fell into ruin.

The tree is often called the “Silken Thomas Tree” after Thomas Fitzgerald, the 10th Earl of Kildare, who led a rebellion against the English authorities during the time of Henry VIII. He acquired the nickname “Silken Thomas” because of the ribbons of silk worn by his supporters. Needless to say, the rebellion failed and his family castle was destroyed. Thomas surrendered, throwing himself on the mercy of the King. That went exactly as well as you might have expected: Thomas was executed, along with several members of his family, in 1537.

The tree, of course, pre-dates Silken Thomas by three centuries, but legend has it that he played a lute under the boughs of the tree the night before he surrendered to King Henry VIII.

All that is quite interesting but doesn’t answer the question of which trees make me sneeze…

R. I. P. John Conway (1937-2020)

Posted in Biographical, mathematics with tags , , , on April 12, 2020 by telescoper

I’ve just heard the sad news that that mathematician John Horton Conway has passed away at the age of 82.

John Conway made very distinguished contributions to many areas of mathematics, especially topology and knot theory, but to many of us he’ll be remembered as the inventor of the Game Of Life. I’ll remember him for that because one of the very first computer programs I ever wrote (in BASIC) was an implementation of that game.

It’s a great illustration of how simple rules can lead to complex structures and it paved the way to a huge increase in interest in cellular automata.

I think he got a bit fed up with people just associating him with a computer game and neglecting his deeper work, but he deserves great credit for directly or indirectly inspiring future scientists.

Rest in peace John Conway (1937-2020).

Testing Times

Posted in Biographical, Covid-19 with tags , , on April 12, 2020 by telescoper

Today is April 12th which means, astonishingly, that it’s just one month since Ireland went into the first stage of its current lockdown. I say “astonishingly” because it seems much longer ago than that!

I know I’m not the only person who is finding it difficult these days to keep track of the passage of time. The lack of a regular routine seems to be the reason. The solution, I imagine, is to try to impose a timetable on yourself rather than have it imposed upon you by someone else. I’ve only been partially successful in that, probably because I lack the necessary self-discipline. Still, somewhat to my surprise, I am not having any significant problems sleeping.

Anyway talking about testing times, I wanted to make a quick comment on the Covid-19 situation in Ireland. I’ve been keeping track of the statistics on my page here, which I shall continue to update as things develop. The latest plot is as follows.

The last two points in the orange curve show a bit of a spike. That is because they include the results from a batch of about 6000 swabs sent for testing to Germany. These should be apportioned to earlier dates but lacking the information needed to do this in a sensible way I’ve just plotted them when the results were received (Friday and Saturday). This also means that the slight inflection in the blue curve is not real, but it doesn’t change the general picture significantly.

This is a manifestation of a major difficulty that the authorities in Ireland are facing, which is the capacity to do coronavirus testing in sufficient numbers and sufficiently rapidly to enable contact tracing in real time which is needed to further control the spread of this disease. At present only around two thousand tests per day are being done, which is inadequate.

Although the recent upward blip is an artefact, the fact remains that there is no evidence that the number of new cases is reducing sufficiently quickly for the relaxation of the rules to be considered feasible. There is a real danger that if the number of new cases does not stop falling soon, the number of patients needing intensive care will exceed the resources available.

Anyway, I reckon things will stay as they are until June at the earliest, so we’ll just have to get used to it!

Winging IT

Posted in Biographical, Covid-19, Education with tags , , , , , on April 2, 2020 by telescoper

The current restrictions resulting from the Covid-19 outbreak have forced many of us academics to adapt to using IT in ways we hadn’t even imagined just a month ago. It’s not only remote teaching via virtual learning environments with live and/or prerecorded video lectures, but also meetings held by videoconferencing platforms such as Zoom or Microsoft Teams.

Few of us have had much training in the use of these things, so when it comes to Information Technology we’re all winging it. Still, necessity is the mother of invention and we just have to get on with it.

I’m gradually getting used to Microsoft Teams, for example. I’ve even got proper kit to wear.

Incidentally, yesterday I learned that the expression ‘to wing it’ actually comes from the Theatre, where it alludes to an actor studying their lines in the wings (at the side of the stage) because they haven’t had time to learn their part before the performance (usually because they are replacing another actor at short notice).

Nowadays ‘winging it’ means generally improvising or making it up as you go along. I’m finding winging it to be rather hard work but quite fun, actually. While we’ve been trying to flatten the Covid-19 curve the learning curve has definitely been getting steeper.

The 2km Limit

Posted in Biographical, Maynooth with tags , , on April 2, 2020 by telescoper

Under the Covid-19 restrictions currently in force in Ireland we’re not supposed to journey further than 2km from home.

The other day I went to the shops near me and decided to try out a helpful app that draws the 2km limit on a map.

Here’s what I got:

So it seems I can go anywhere in Maynooth without breaking the rules. Alarmingly, however, I see that if I’m not careful I could end up crossing the border from County Kildare into County Meath!

Towards the South is the famous Junction 7 on the M4 which in normal times features on the traffic news on the radio with alarming frequency because of one snarl up or another. I don’t suppose there will be much more of that for a while.

One of the pleasant side effects of the lockdown is a drastic reduction in vehicle traffic. That in turn means that I wake up to the sound of birdsong rather than car engines. That’s one part of this I’ll enjoy while it lasts.

On Boredom

Posted in Biographical, Covid-19, Television with tags , , on April 1, 2020 by telescoper

During this time of isolation and social distancing I’ve noticed how many people are posting messages on social media about being bored.

Conscious that I am in danger once again of being excluded from a popular cultural phenomenon I have been trying recently to join in this craze. Unfortunately whenever I try to experience a bit of boredom I find there is far too much to distract me.

There’s working from home, of course: lecture recordings to make, notes to prepare, assignments to correct, virtual meetings to attend, papers to write, and so on

But outside of work it’s just as difficult. Whenever I try to interrupt my day with a bit of boredom I find that there’s so much music to listen to, so many books and newspapers to read, so many crossword puzzles to solve so many other things to do, that I always get distracted and fail dismally.

Perhaps it is the fact that I don’t have a television set that makes me such a failure? It seems that there may be a strong correlation between possession of a TV and being susceptible to boredom. Perhaps if I bought one I could be more like normal people?

Anyway, never let it be said that I don’t know when I’m beaten. That is why I am asking readers of this blog for help. Could anyone who is expert in being bored please send tips on how to achieve it? I’d be quite interested in your suggestions.

Your advice through the comments box would be greatly appreciated as I fear that without it I may always remain a social outcast.

P. S. Before anyone says it: if you are yourself struggling to get bored you could try reading through the back catalogue of posts on this blog!

Health and Safety

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

Among the additional measures introduced last night to combat the spread of Coronavirus in Ireland was the cancellation of all non-essential medical appointments.

Looking at my diary I realise that I was due to have a checkup on my knees next Friday. That won’t be happening now I suppose.

It’s about three months since I had steroid injections in both knees to halt the arthritis therein. The jabs were quite painful but worked very well and I have been able to dispense with the use of a walking stick since I had them.

The effect of these injections only lasts a few months so I was due an inspection to see if I might further ones in the near future. I think I’m doing OK, however, and I’m sure the hospitals have more important things to be dealing with right now, so I don’t mind the deferral at all.

Although I haven’t really needed my walking stick recently I think I might start carrying it again on the rare occasions I go out during the ‘lockdown’ – so I can hit people with it if they get closer than 2m from me.

Life going on..

Posted in Biographical, Covid-19 on March 26, 2020 by telescoper

I’ve had the feeling that this blog is in danger of turning into some sort of plague diary so I thought I’d pass on a couple of examples of life going on. It’s not quite business as usual, but there’s no point in us sitting around feeling sorry for ourselves.

As it happens I came onto campus today, mainly to check on the Library Cat (who was absent from his post, but well provisioned with food) but also to check the Departmental mail. Somebody has to deal with the invoices, or at least the minority of them that don’t come electronically. In fact there were only two.

Anyway, as I walked through campus I saw the building work on the Kilcock Road site continuing apace. It can’t be difficult to practice social distancing at the top of one of those cranes:

The last picture I took of the construction site was on St Patrick’s Day (17th March), just nine days ago:

It’s from a different vantage point, but you can still see they’ve added quite a lot in the past week and a bit. You can also see how much the weather has improved. In fact the last few days have been lovely!

Another thing worth reporting on is that there’s been a notable uplift in submissions to the Open Journal of Astrophysics recently. It’s almost as if some people have got some time on their hands to write papers! I’ll do a separate post about a few developments on the OJA front in due course but, for the time being, I will just mention that as a fully online journal all our processes run remotely anyway so we are, and will remain, fully operational throughout the Coronavirus emergency.

Well, now I have to get my act together and activate another remote computational physics laboratory session. Fingers crossed!
