Sax and the Single Man

Posted in Biographical, Covid-19, Music with tags , on March 16, 2020 by telescoper

I heard on Friday that my upstairs neighbours were going away for a few days for the St Patrick’s Day break, so I took the opportunity afforded by this solitude to take this baby out of its box and have a bit of practice.

I don’t have my usual tenor sax with me in Maynooth: it’s in safe (?) keeping elsewhere (that’s a long story). Here it is, pictured a few years ago in my house in Cardiff:

 

The soprano sax may be a much smaller and lighter instrument than the tenor but it is more of a handful to play in tune. I always thought this was my own incompetence but it seems to be agreed by proper musicians.

My usual practice is to warm up with scales and other exercises then play along a bit with some backing tracks made for the purpose with just a rhythm section. Playing simple riffs on the chords is a good way to settle in, then you can start to improvise properly.

I wouldn’t say my attempts to revive my long neglected musicianship have been very successful so far – not least because they were never very good in the first place – but it’s a nice diversion.

I suspect that many people will be looking for things to do to stop them getting bored over the next few weeks and months.

Business (Cards) as Usual

Posted in Biographical, Covid-19, Education, Maynooth with tags , , on March 15, 2020 by telescoper

One of the things that happened just before Maynooth University closed down last week was that I received delivery of my new business cards:

I’m sure they will prove useful at some point in the future, but I can’t see myself handing any out for a while!

I have subtly removed the telephone numbers from the above image because I was warned that people could use my number to do nefarious things, such as trying to contact me. They are my work numbers, of course, so I never answer them anyway, but you can’t be too careful.

Incidentally, today the Taoiseach Leo Varadkar announced that pubs and bars in Ireland should close down until March 29th, which will include the St Patrick’s Day holiday on Tuesday. I don’t know why this wasn’t done earlier and wonder how many people have been infected with Coronavirus because of the delay.

Anyway, after a weekend of not working, tomorrow we resume working from home. Fortunately it’s Study Week so we don’t have to try doing remote teaching until next week.

A Sign of Panic Buying?

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

The media are full of stories of people panic buying and hoarding various items, chiefly toilet tolls and hand-wash, but also food. I hadn’t seen much evidence of that in Maynooth until I noticed this sign yesterday outside the Roost:

I had no idea food shortages were so bad. I tried following the advice on the notice, but found the door a bit too chewy for my taste.

A few minutes later I was in Supervalu doing my regular Saturday shop without problems.

But seriously folks everywhere, there is absolutely no need to stockpile groceries. It won’t do you any good and it may seriously inconvenience others. There’s plenty to go round if we all behave reasonably, so show a bit of civic responsibility and think of your fellow humans!

In other words, don’t be like this:

Anyway, one thing I have been stockpiling is crosswords and I’m going to spend most of today doing them!

Survivors!

Posted in Television with tags , on March 14, 2020 by telescoper

Who among you is old enough to remember the 1975 TV series Survivors?

I remember it well, as it scared me to bits. I never figured out, though, why if 99% of the human race had died, why were there no bodies anywhere?

Struttin’ With Some Barbecue

Posted in Jazz with tags , , on March 14, 2020 by telescoper

Not long ago I shared a piece by the quartet that was led for a short time by Ruby Braff (cornet) and George Barnes (guitar). By way of a distraction I thought I’d share another track from the same album that one came from. Struttin’ with some Barbecue was written way back in the 1920s by Lil Hardin, and it became a bit of a showpiece for her husband, a gentleman by the name of Louis Armstrong. The title is not about outdoor dining arrangements, but roughly translates from the slang of the time as `Dancing with an extremely sexy partner’. Or perhaps a bit more than `Dancing’!

Anyway, this is another lovely performance and there’s a very special moment at about 3:09 where Messrs Braff and Barnes exchange leads in brilliantly telepathic style!

Working from Home

Posted in Biographical, Covid-19, Maynooth on March 13, 2020 by telescoper

Today was my first day of “working from home” after the closure of Maynooth University campus yesterday. As I live close to the campus I did venture out from home to perform various duties thereon (see picture).

Before the closure yesterday I was told some grim stories about panic buying in Maynooth but when I went to the local Supervalu around 7pm there was plenty of stuff on the shelves. I treated myself to some nice wine after a very stressful day.

This morning I did indeed work from home, getting on with some writing until lunchtime while still in my dressing gown.

Working from home isn’t that easy. Without the discipline imposed by having to go to work at a specific time it’s tempting just to potter about uselessly. You have to force yourself to focus but also remember to take breaks, which you don’t usually have to do during the course of a working day as, e.g., lunch is part of the regular timetable.

I’ve found that what works for me when working at home, is to divide a say into two-hour blocks, after which I break for 30 minutes to have a cup of tea or a snack.

I did two such blocks this morning, after the second of which I checked my email while having a sandwich. The deluge of messages in my inbox contained a number that I needed stuff from my office to deal with (including the publication of an Open Journal paper).

When I got there campus was quiet, unsurprisingly, but there were a few people around, including some of our research students. It all felt a bit unreal, but I think it might be the reality for some time now.

I have been pretty effective at self-isolation and social distancing for many years now, so I think I’ll be OK with this.

New Publication at the Open Journal of Astrophysics!

Posted in OJAp Papers, Open Access, The Universe and Stuff with tags , , , , , , , on March 13, 2020 by telescoper

Well Maynooth University may have shut down but the The Open Journal of Astrophysics certainly has not.

In fact we have just published another paper! This one is called Halo Spins from Primordial Inner Motions and the first author is Mark Neyrinck (based in Bilbao). The other authors are Miguel Aragon-Calvo (based in Mexico), Bridget Falck and Alex Szalay (based in the USA) and Jie Wang (China).

Here is a grab of the overlay:

You can find the arXiv version of the paper here.

As an added bonus there are some groovy videos to go with this paper:

You might have to read the paper, however, to understand exactly what they mean (although they are very pretty anyway).

Closing Down in Maynooth – Updated

Posted in Maynooth on March 12, 2020 by telescoper

Not unexpectedly the (acting) Taoiseach Leo Varadkar has announced that from 6pm today all schools college and cultural institutions will close until 29th March. Indoor events involving more than 100 people will be banned, as will outdoor events involving more than 500 people.

I think this decision is sensible, if perhaps a bit late. I am less convinced that it is sensible to allow pubs and restaurants to remain open.

We await full instructions on exactly how the closure will be implemented at Maynooth University but it is clear that teaching and student attendance on campus will be suspended for the period announced. As I outlined yesterday we have a Study Week next week so the as things stand we will have to deliver teaching remotely for the week after that. We have been undertaking contingency planning for this eventuality.

It is possible that staff will still be able to come on campus during the closure, but it is obviously better if they work remotely in accordance with the policy of `social distancing’.

I will update with further details as soon as they are available.

Update: we may be closing at 6pm, but I have a Computational Physics lab from 2pm to 4pm and that is going ahead as planned!

Another Update: Here is an excerpt of an email from the University outlining the extent of the closure:

Lectures, tutorials and practical classes are cancelled. It is important that from Monday 23rd March, as reading week concludes, that we provide as much on-line teaching and student support as possible to facilitate student learning. We know that departments have been making preparations, and recognise that while there are some colleagues proficient in blended learning, for others remote teaching will present challenges. The Vice-President Academic and the Dean of Teaching and Learning will circulate guidance and some additional resources tomorrow.

The University will continue to operate, but most teaching and much of its work will be done remotely. Research students and staff who need access to campus facilities will continue to be able to do so, unless advised otherwise by the Head of Department. Most campus buildings will remain open. A number of students will remain in residence. Given the public health objectives of the government decision, all staff who can work effectively from home are asked to do so. However, in order to maintain effective operations, some staff will need to be present on campus, with appropriate precautions. Your Head of Department or Manager will confirm if you need to be present and work on campus.

The student services, including the health centre and counselling will remain open, and students are being advised to contact these offices by email or phone, rather than in person. The University Library will be closed but will maintain a limited service for borrowers. Most catering outlets, the sports facilities and the crèche will be closed.

The University residences will remain open. Students who were planning to go home for reading week have been advised to go home, and to stay at home until lectures resume. International students and others who are unable to leave or do not wish to leave will continue to be accommodated as normal.

All events on campus will be cancelled, and face-to-face meetings, internal or external, should be kept to a minimum, with virtual meetings preferred.

The full advice from Maynooth University can be found here.

As a Head of Department I have informed all staff that they can (and should if it all possible) work from home for the period of the campus closure.

Break Points

Posted in Biographical, Covid-19, Education, Maynooth with tags , on March 11, 2020 by telescoper

It is now Week 6 of the Spring Semester at Maynooth University.  My lectures on Engineering Mathematics take th place on Monday, Tuesday and Wednesday so today I gave the 18th of the semester, which means I am halfway through the module. Next week is a scheduled Study Week so there are no lectures planned after this Friday until 23rd March. Just two days to go before the breaking

It remains to be seen whether teaching does indeed resume on that day. If the coronavirus situation in Ireland gets much worse we may stay closed for a longer period.

There is a subdued mood around campus, and the number of students in my class this afternoon was significantly lower than usual. I don’t know whether that is because of coronavirus or because some students have headed home early for the break or because they didn’t fancy learning about curves and tangent vectors!

Last night the University issued updated guidance. The main thing is that we stay open but the Conferring Ceremonies for postgraduate degrees scheduled for Thursday and Friday next week have been postponed indefinitely.  The students will formally receive their degrees in absentia although they will (hopefully) be able to attend a ceremony to get their certificates in person at some point in the not-too-distant future.

I blogged on Monday about contingency planning and I’ve been spending quite a lot of time this week making the best arrangements possible for students in case we don’t reopen on 23rd March. That includes getting all the notes and examples sheets ready for Engineering Mathematics, which is now done.

My other module is Computational Physics. For that one there’s a small project that the students do (usually) in pairs. I published the list of projects for the students to pick from earlier than originally planned and will hopefully be able to allocate them before the end of this week. That way, if there’s a campus closure they can at least get on with their projects. Fortunately Python is free so they can run code on their laptops. All the other resources for that module will be available online too so disruption shouldn’t be too bad: even if we have to cancel the laboratory sessions the students can still work through the scripts on their own.

What will happen with examinations is not yet clear, but those don’t take place until May so they’re not the immediate priority!

I asked the students in my Engineering Mathematics at the end of this afternoon’s lecture please to keep an eye on their email and social media for announcements about changes in the situation. The positive message for students is that they are actually at very low risk of serious illness themselves (although they should of course take precautions to ensure they don’t infect others).

I feel a bit guilty for thinking about the positive message for staff, but I do have quite a bit of writing-up to do and a nice long campus closure would seem to provide an ideal opportunity to `self-isolate’ and get on with it. For the time being, though, it’s business as usual…

Brave World, by Tony Hoagland

Posted in Poetry with tags , , , on March 11, 2020 by telescoper

But what about the courage
of the cancer cell
that breaks out from the crowd
it has belonged to all its life

like a housewife erupting
from her line at the grocery store
because she just can’t stand
the sameness anymore?

What about the virus that arrives
in town like a traveler
from somewhere faraway
with suitcases in hand,

who only wants a place
to stay, a chance to get ahead
in the land of opportunity,
but who smells bad,

talks funny, and reproduces fast?
What about the microbe that
hurls its tiny boat straight
into the rushing metabolic tide,

no less cunning and intrepid
than Odysseus; that gambles all
to found a city
on an unknown shore?

What about their bill of rights,
their access to a full-scale,
first-class destiny?
their chance to realize

maximum potential?-which, sure,
will come at the expense
of someone else, someone
who, from a certain point of view,

is a secondary character,
whose weeping is almost
too far off to hear,

a noise among the noises
coming from the shadows
of any brave new world.

by Tony Hoagland (1953-2018).
