Level 5 New Year

Posted in Biographical, Covid-19, Maynooth with tags , on December 30, 2020 by telescoper

To nobody’s surprise the Taioseach this evening announced that the whole of Ireland would go immediately into full Level 5 Covid-19 restrictions. Officially these will apply until January 31st, but nobody thinks they will end then. Nor should they. The past few days have seen the number of cases and hospitalizations skyrocket and the current positivity rate of tests is 10.5% (7-day average) with a figure of 18% recorded yesterday.

Here are the latest plots of 7-day averages. First, logarithmic:

Second, linear:

I’m not alone in thinking that it was a very big mistake to relax the restrictions in early December, but that’s done now and we have to deal with the situation as it is now. Unfortunately the Christmas wave hasn’t really hit these figures yet so I think thinks are going to get a lot worse before they get better. The current exponential phase with a R number of around 1.6-1.8 means the cases will probably double by this time next week.

Anyway, looks like a quiet night in for New Year’s Eve (not that I mind that) and my horizon for January is back down to a 5km radius, although its centre has shifted a little as I have moved house since last time!

Yule Blog

Posted in Biographical, Maynooth on December 24, 2020 by telescoper

It’s Christmas Eve at last. This morning I ventured out briefly to buy a newspaper. That was more problematic than I’d anticipated as most newsagents in Maynooth had sold out of the Irish Times. There won’t be an edition until next Monday so people had got theirs early. I did eventually manage to find a copy however and did the Christmas Crosaire crossword when I got back home.

With that errand out of the way it is now my plane to stay at home alone until Sunday 27th at the earliest. The reason for that is the very dangerous Covid-19 situation, with another 922 cases reported today. Cases in Ireland aren’t as high as in many other European countries but are going quicker than any at this time. The official advice is to minimize social interactions over the Christmas period, so I’m doing that. Zero is the minimum in my case.

In case you think I’ll be miserable here on my own, I assure you that I won’t. I’ve got plenty of things to do, and plenty to eat and drink. I’m quite proud of the fact that I bought six bottles of wine last weekend and managed not to drink any until today!

I’m not myself of that faith (or indeed any) but I understand it is a Catholic tradition to eat fish the day before a Feast Day. This evening I’ll be cooking Sea Bass with a lemon and dill sauce and Mediterranean roast vegetables. That’s not because I’m becoming a Catholic but because of balance for the next two days. To go with the fish I’ll be drinking a nice Pouilly-Fumé. I’ll bore you with the menu for the next two days when I get to them (assuming no culinary disasters).

Update:

I know it doesn’t look great – the fish didn’t want to come out in one piece – but it tasted delicious!

Incidentally, it is interesting that almost nobody here uses “Boxing Day” to refer to the day after Christmas Day. It’s “St Stephen’s Day” or just “Stephens Day”.

I realized this morning that this will be the very first Christmas I’ve ever spent outside the United Kingdom. The vast majority of Christmases Past I’ve been in Newcastle, but I have also over the years been in Brighton, London, Nottingham and Cardiff at this time of year.

I’ll end with the official Christmas greetings from Maynooth University!

Lecture Summary

Posted in Biographical, Education, Maynooth with tags on December 16, 2020 by telescoper

Yesterday I gave my last full lectures of the term. The picture shows a summary of my final lecture on Mechanics & Special Relativity for first-year students. It may look a bit thin on content but I’m very tired. How I managed to pad it out to 50 minutes I have no idea.

Today we have presentations by project students via Microsoft Teams which I can watch from home while I await the delivery of a blackboard which I’m going to put in my study at home. (UPDATE: Predictably, the Courier didn’t show up.)

Later today I have my last lecture slot which I will use to pass on some information about the examination online timed assessment in January.

And that will be the end of my teaching for the (calendar) year, which seems to have lasted at least a decade. Let’s hope next year is better.

Vaccination Priorities

Posted in Covid-19, Education, Maynooth on December 15, 2020 by telescoper

In the news today is the fact that the Irish Government “rolled out” (I hate that expression) its Covid-19 vaccination plans. These are summarised here:

I’m not at all surprised to see that I’m in a low priority category, although I beat some of my colleagues in the University sector by one notch by virtue of being over 54 years of age!

It seems likely that they won’t get around to the likes of me until well into the summer, but at least there’s a plan.

The lack of imminent vaccination for staff or students and the strong likelihood of a post-Christmas spike of Covid-19 cases means that there is no realistic prospect of a significant increase in on-campus teaching in this academic year. We have therefore taken the decision to keep our teaching entirely online next Semester. Hopefully things will start to improve from September 2021.

The Advent of Covid

Posted in Biographical, Covid-19, Maynooth on December 10, 2020 by telescoper

I witnessed this disturbing scene last night as I walked home through Courthouse Square in Maynooth. Look at them – not a single one wearing a mask!

Perhaps however they have formed a social bubble so we can forgive that, and the lack of social distancing?

Nevertheless I was confused as to what was going on until I worked it out. The child in the front has obviously fallen asleep with its head on a Frisbee and the others are waiting for it to wake up so they can get it back.

With this Mystery solved, continued my journey to Supervalu, where they were sadly out of Gold, Frankincense and Myrrh so I bought a bottle of wine instead.

Time for Resilience?

Posted in Education, Maynooth with tags , on December 8, 2020 by telescoper

I’ve just received an invitation to a two-hour seminar on Resilience for Heads of Department. I post the description here:

Sadly I don’t have time to attend this, as it is right in the middle of a teaching day in the last week of an absurdly busy term and it clashes with a previous commitment. I can’t see yet another two hour meeting on Zoom doing much for my wellbeing anyway, especially when I’ve already been running on empty for weeks.

I will be “taking the time to renew and refresh” after December 18th, when I’ll have the first proper holiday I’ve been able to take since March. I’ll probably spend most of that asleep. Or maybe “resilience” is all about adapting to life without any time off?

“We know we’re working you into the ground, but if you learn how to be *resilient* we might might get a few more months out of you before you crack.”

Sharpening the Saw seems like an interesting book. I wonder what the sequel is,  Wielding the Axe?

 

Another Week Ending

Posted in Biographical, Covid-19, Education, GAA, Maynooth, The Universe and Stuff on December 4, 2020 by telescoper

As this term staggers on I once again arrive at a weekend in a state of exhaustion. Still there are just two teaching weeks left for this term so soon it will be the Christmas break. At least there won’t be any teaching then, though there will be other things to do before the examinations start in January.

I’ve managed to keep a reasonable pace up in both sets of lectures. The last one due this term is for Vector Calculus and Fourier Series, on Friday 18th December, but I think I may be able to complete the module content on the Tuesday lecture which means the students will be able to have a bit more time to relax before Christmas or, alternatively, a bit more time for revision. I hope it’s the former, as I imagine the students are at least as tired as we staff are. This has been a difficult year for everyone.

At Maynooth University, lectures for Semester 2 start on February 1st 2020. That will give us a bit of time to see how the Covid-19 pandemic progresses before deciding exactly how we’re going to approach teaching. Other universities that resume earlier have less time to make this decisions. I fear that the number of cases may rise rapidly over the three weeks remaining before Christmas, even before the Christmas break itself, and we therefore might have to go fully online next term. What I don’t want to happen is what happened in September, namely that we made elaborate plans for lecture rotations and tutorial groups that were then ditched because the Coronavirus situation changed. That was quite demoralizing because it involved a great deal of effort that was wasted.

Being a Department of Theoretical Physics we don’t have the problems facing the more experimental subjects that require extensive laboratory classes which are difficult to do under social distancing. Next term however we do have Computational Physics, which has laboratory classes, so I’ll have to decide how much of that we can do in person and how much students will have to do online using their laptops. I hope we can return to full in-person lab sessions, but we can’t be that will be possible right now. In any case computer labs are far easier to run online that practical chemistry or physics labs, so I think we will be able to do a reasonable job whatever the circumstances.

For added fun, next term I’ll be teaching a new module; 4th Year Advanced Electromagnetism. Although there’s always a lot of work required to teach a module for the first time, I am actually looking forward to doing this one as there’s some interesting physics in it (especially relativistic electrodynamics). I may try to squeeze a bit of plasma physics in too. But will it be online or on campus, or a mixture of both? Time alone will tell.

Anyway I’m looking forward to this weekend being as stress-free as possible. There’s a good start tonight, as Newcastle’s game against Aston Villa has been postponed due to Covid-19 so no anxious looking at the score this evening. The rest of the weekend will be dominated, for me, by the two semi-finals of the All Ireland Gaelic Football Championship (Cavan versus Dublin tomorrow and Mayo versus Tipperary on Sunday). It seems to be written in the stars that the final should be Dublin versus Tipperary, the two teams that played on Bloody Sunday, but time will tell on that one too.

Update: Dublin did indeed comfortably beat Cavan on Saturday but Mayo beat Tipperary in a high scoring game in a foggy Croke Park on Sunday (Mayo 5-20 Tipperary 3-13). The final will therefore not be a rerun of the 1920 final.

That’s enough rambling. Have a good weekend.

Cosmology Talks: Eiichiro Komatsu & Yuto Minami on Parity Violation in the Cosmic Microwave Background

Posted in Cardiff, Maynooth, The Universe and Stuff with tags , , , , , , , , on December 2, 2020 by telescoper

It’s time I shared another one of those interesting cosmology talks on the Youtube channel curated by Shaun Hotchkiss. This channel features technical talks rather than popular expositions so it won’t be everyone’s cup of tea but for those seriously interested in cosmology at a research level they should prove interesting.

In this video, Eiichiro Komatsu and Yuto Minami talk about their recent work, first devising a way to extract a parity violating signature in the cosmic microwave background, as manifested by a form of birefringence. If the universe is birefringent then E-mode polarization would change into B-mode as electromagnetic radiation travels through space, so there would be a non-zero correlation between the two measured modes. They  try to measure this correlation using the Planck 2018 data, getting  a 2.4 sigma `hint’ of a result.

A problem with the measurement is that systematic errors, such as imperfectly calibrated detector angles,  could mimic the signal. Yuto and Eiichiro’s  idea was to measure the detector angle by looking at the E-B correlation in the foregrounds, where light hasn’t travelled far enough to be affected by any potential birefringence in the universe. They argue that this allows them to distinguish between the two types of measured E-B correlation. However, this is only the case if there is no intrinsic correlation between the E-mode and B-mode polarization in the foregrounds, which may not be the case, but which they are testing. The method can be applied to any of the plethora of CMB experiments currently underway so there will probably be more results soon that may shed further light on this issue.

Incidentally this reminds me of Cardiff days when work was going on about the same affect using the Quad instrument. I wasn’t involved with Quad but I do remember having interesting chats about the theory behind the measurement or upper limit as it was (which is reported here). Looking at the paper I realize that paper involved researchers from the Department of Experimental Physics at Maynooth University.

P. S. The paper that accompanies this talk can be found here.

Virtually Open Saturday at Maynooth

Posted in Education, Maynooth on November 28, 2020 by telescoper

Today is the second of two consecutive Virtual Open Days here at Maynooth University so here I am sitting in front of my computer at home on a Saturday morning answering questions from prospective students about Theoretical Physics courses. The first day was more about clubs and societies and other aspects of student life at Maynooth so I wasn’t involved so much in that. Today is about courses of study so I’m here fielding questions for my Department.

With about an hour gone since we opened at 10am it’s been quite busy, but at least I’ve either known, or had access to, the information needed to be able to answer the questions asked! So far. If questions keep coming at the same rate for the next three hours I’m going to need quite a lot of coffee to keep me going!

At least I can do this from the comfort of my own home. It’s a rather cold and miserable day outside. The weather turned much colder a couple of days ago, and the temperature was below freezing last night. There was a hard frost covering my garden when I got up this morning. Winter draws on.

Anyway, I’ll be online until 2pm, which fortunately will give me plenty of time to do some things I need to do before watching the Semi-final of the All Ireland Senior Hurling Championship between Waterford and Kilkenny, which starts at 6pm…

UPDATE: It was a remarkable game of hurling, Waterford looking dead and buried at half time but turning it around in amazing fashion  in the second half to win 2-27 to 2-23. Greatest comeback since Lazarus.

Maynooth University Open Days!

Posted in Education, Maynooth with tags , , on November 26, 2020 by telescoper

It’s almost time once again for our autumn open days at Maynooth University. This autumn the two days are virtual events but also differ in that the first day is devoted to clubs, societies and other wider aspects of student life while the second is dedicated to information about the academic side, i.e. courses of study.

I’ve recorded some video material that will be used on the second day and I’m also going to be online on Saturday from 10am to 2pm to answer questions from prospective students. In order to experience these and other delights you have to register, which you can do here.

Here is a video tour of the Maynooth University campus, filmed in better weather!

You will see that it includes an artist’s impression of the new building on the North Campus which isn’t actually finished yet, but which is coming along nicely.

And here is a gratuitous picture of our star attraction:
