Beard of Ireland 2020 poll sees record turn-out

Posted in Beards on March 11, 2020 by telescoper

I just checked the state of the voting in this year’s Beard of Ireland poll and, no doubt owing to some form of administrative error, I seem to be in the lead!

There are still several days to go however and things often change rapidly as these polls enter the final stages.

The really good thing about this poll is that it’s generating so much interest. I hope this may help counter some of the blatant pogonophobia going around because of the Coronavirus emergency.

BEARD OF IRELAND 2020 POLL SEES RECORD TURN-OUT

The Beard Liberation Front, the informal network of beard wearers, has said that competition for the Irish Beard of the Year title has seen a record turn-out with votes cast so far already more than 500% up on 2019.

The campaigners say this reflects an increased awareness of the importance of beards in public life in Ireland

The 2017 winner was politician Colum Eastwood who bearded broadcaster William Crawley for the annual Award.

In 2018 the DUP’s Lee Reynolds shaved writer Dominic O’Reilly for the honour with Colum Eastwood in a steady third place.

In 2019 Lee Reynolds retained the title

The vote ends at midnight on 15th March with the 2020 winner announced to mark St Patrick’s Day on 17th March

The BLF says that while traditionally a…

An Astronomical Anniversary

Posted in Biographical, History, The Universe and Stuff with tags , , on March 10, 2020 by telescoper

I was reminded via Twitter that today is the 200th anniversary of the first formal meeting of the Astronomical Society of London which took place on 10th March 1820. This society turned into the Royal Astronomical Society when it was given a Royal Charter in 1831. Here is the first page of the the Minutes of that first meeting:

Those of you who have been paying attention will recall that the decision to form the Society was taken at a dinner in January 1820 and the bicentenary of this event was celebrated in January by the RAS Dining Club (of which I am a member).

Club Dinners usually take place after the Open Meetings of the Royal Astronomical Society on the second Friday of the month. Sadly, however, there won’t be a Club Dinner this Friday as it has been cancelled owing to the Coronavirus emergency. I’ll have to make do with beans on toast again then.

Incidentally, I thought I’d share this list of the first 200(ish) members of the Royal Astronomical Society (PDF) kindly sent to me by former Cardiff colleague Mike Edmunds. There are some illustrious names among the early members, including Laplace and Bessel, as well as some oddities, such as His Excellency Alexis Greig (Vice Admiral of the Imperial Russian Navy) and Edward Riddle, Esq. (First Mathematical Master, the Royal Naval Asylum).

Coronavirus Contingency

Posted in Covid-19, Education, Maynooth with tags , , , , on March 9, 2020 by telescoper

Today we heard that the annual St Patrick’s Day Parades due to take place around Ireland next week on 17th March have been cancelled. Although it seems the Government was reluctant to take this decision, it seems to me an entirely sensible precaution.

I also noticed an article this weekend that academic staff at a St Mary Immaculate College in Limerick have been asked to draw up “…contingency plans for delivering module content in the event of there being on-campus restrictions due to the coronavirus.”

I’d be very surprised if there is an educational institute that has not asked staff to undertake contingency planning of this sort. It would indeed be irresponsible to fail to plan for such an eventuality. The fact that such processes are going on is no reason at all for students or staff to feel anxious.

All Heads of Department here at Maynooth (including myself) have been briefed about the University’s contingency planning and have in turn briefed their staff. In general this planning, which is led by the official advice from the Health and Safety Executive (HSE), seems sensible and proportionate. It also seems very similar to what is going on in Limerick.

For the time being here in Maynooth teaching carries on as normal, but if the situation deteriorates and the advice from HSE changes then contingency arrangements will be adopted. That may include restricting student access to campus and delivering some teaching online instead of in person. That won’t be ideal but it could be managed and we’ll do it circumstances require it.

We have a Study Week break for the week including St Patrick’s Day so after this Friday students won’t be on campus in large numbers anyway. That gives us a bit of time to assess developments.

In the meantime I’ll just share the official poster again.

Maynooth’s Creation

Posted in Maynooth, Music, The Universe and Stuff with tags , , , , on March 8, 2020 by telescoper

As it was foretold, this afternoon to the College Chapel at Maynooth, which looks like this inside:

This was in fact the first time I’ve set foot inside the Chapel. The occasion was the annual Spring Concert by Maynooth University Choral Society, accompanied by the Irish Choral Sinfonia, in a performance of Haydn’s great oratorio The Creation.

It’s worth mentioning that Haydn started preparing to write his Creation in 1796, which is just a year after St Patrick’s College in Maynooth was established (as the National Seminary of Ireland). This work was therefore was a good choice for the year in which the College celebrates the 225th year of its own creation.

Although the College Chapel is quite large it provided a very intimate setting for this great masterpiece (in that the audience was very close to the musicians and singers) and provided a very distinctive acoustic. Curiously, this was the first time I had heard this work performed in English.

The solo vocalists – Claudia Boyle (soprano), Andrew Gavin (tenor) and Simon Morgan (bass) – were all excellent, as were the choir and orchestra. All in all it was a hugely enjoyable experience, even if the wooden seats were a bit unforgiving!

After the performance there was a Buffet Supper in Pugin Hall, which I had assumed would just be sandwiches but which turned out to be a very nice meal with wine at which I got chatting to some very friendly people. Admission to the event was by invitation only, but the guest list was not restricted to folk from Maynooth University.

As the token astrophysicist present a few people asked me what was shown in the picture on the cover of the programme. Not being a proper astronomer I didn’t know but I am reliably informed that it is the Eagle Nebula (M16), though it is reversed left to right which I claim as an excuse for not recognising it…

R.I.P. McCoy Tyner (1938-2020)

Posted in Jazz with tags , , , , on March 7, 2020 by telescoper

I had just got home last night when I heard the sad news of the death at the age of 81 of the brilliant pianist McCoy Tyner. When I was looking through my collection of jazz recordings after hearing about this I was struck by how many of them featured McCoy Tyner, most of them in association with John Coltrane that lasted about five years. Tyner’s style was enormously influential as well as immediately recognizable, especially for the way he used his left hand to punch out chords in much the same way as a right-handed boxer uses his left jab.

Tyner had a very long career as a solo musician and it would be wrong the give the impression that his work with Trane from about 1960 to 1965 was all he did, but when choosing something to share in his memory I kept coming back to that period.

In the end I decided to post a classic piece from the John Coltrane era. This is the title track from the 1961 album My Favorite Things which, as it happens, is one of my favourite things. Coltrane plays soprano sax on this track; apparently he hadn’t played a soprano sax at all until 1960, when Miles Davis bought him one. I like its use on this particularly recording as it gives the performance a very “Eastern” sound.

You might think that a song from The Sound of Music would be unlikely material for John Coltrane to tackle, but in fact he does something extremely interesting with it: the melody is heard numerous times throughout the track, but instead of playing solos over the written chord changes, the soloists improvise over just two chords, E minor and E major, in a manner that seems influenced by Indian music. The whole thing is played in waltz time, but drummer Elvin Jones not only keeps an intense but fluidly swinging pulse going in 3/4 but also does so much around and across that central beat.

The Spread of the Coronavirus

Posted in Covid-19, Uncategorized with tags , on March 7, 2020 by telescoper

I thought I would share the above graphic because provides a simple yet very effective illustration of why
it is so important to delay the spread of the Coronavirus, and why strict precautions are being taken to achive that.

The primary cause of death for patients suffering from COVID-19, the disease carried by this virus is that inflamation of the lining of the alveoli in the lungs makes it harder for oxygen to diffuse across into the capillaries and for carbon dioxide to diffuse out. As outlined in the report I shared a few days ago, severe cases therefore require treatment that involves being supplied with oxygen via a respirator for a long period, perhaps weeks. The number of available respirators and intensive care units generally is likely to prove the factor that limits the capacity of hospitals to cope.

The situation might be worse in England because the NHS only has about 2.3 hospital beds per thousand of the population so the capacity limit may be hit much earlier. For reference, Ireland is not much better on 2.96, Scotland has 4.2 and Germany has 8; see here for OECD figures from other countries.

Delaying the spread of the virus may prevent health services from being overwhelmed by spreading out the peak in the manner indicated in the diagram even if the total number of cases were not to reduce. Pushing back the bulk of the distribution by weeks or months may also help if the virus is seasonal – it may transmit infection less efficiently during the spring or summer than it does during the winter.

In the light of this it can’t do any harm to share the HSE advice for Ireland again.

Now wash your hands please.

Building Up Maynooth

Posted in Education, Maynooth with tags , , , on March 6, 2020 by telescoper

I thought I’d share the above picture as part of an occasional series of updates about the new building going up on the North Campus at Maynooth University.

This artist’s impression of what the new building will look like has appeared on the fence surrounding the construction site; you can see cranes and part of the skeleton of the new structure behind the board.

It looks like the Science Building in which I am currently based will be almost completely hidden from the road: it is the building immediately behind the grey rectangular block to the right of the larger brick-coloured edifice which is the main part of the new structure. The road across the middle of the image that divides the North Campus from the South is called Kilcock Road.

Apparently the new building will be opened early in 2021. I look forward to seeing the new development completed!

From the Inventor of the H-index

Posted in Biographical, The Universe and Stuff with tags , , , , on March 5, 2020 by telescoper

My third-year students are busily engaged with a Computational Physics class test so I thought I’d occupy myself for a few minutes by sharing an interesting little paper that appeared on the arXiv a few weeks ago. The paper is by Jorge Hirsch, the inventor of the (in)famous H-index.

Here is the abstract:

A magnetic field H is expelled from the interior of a metal becoming superconducting. Everybody thinks the phenomenon is perfectly well understood, particularly scientists with the highest H-index think that. I don’t. I will explain why I believe that without Holes, conceptualized by Heisenberg in 1931 fifty years after Hall had first detected them in some metals, neither magnetic field expulsion nor anything else about superconductivity can be understood. I have been a Heretic in the field of superconductivity for over 30 years, and believe that Hans’ little story about the emperor perfectly captures the essence of the situation. Here is (a highly condensed version of) the wHole story.

You will see that, despite the liberal sprinkling of letters H, the paper isn’t ostensibly about the H-index, but it does contain some interesting comments thereon, including:

I proposed the H-index hoping it would be an objective measure of scientific achievement. By and large, I think this is believed to be the case. But I have now come to believe that it can also fail spectacularly and have severe unintended negative consequences. I can understand how the sorcerer’s apprentice must have felt.

I think the opinion of a scientist about the value of the H-index roughly speaking divides according to whether a said scientist has a big one or a small one. Those lucky enough to have a high H-index probably think it is fine, while those who have a low value can probably find a reason why it is flawed. My own H-index (42 according to Google Scholar) is mediocre, which I reckon is a fair reflection of my status.

Farewell to Flybe

Posted in Uncategorized with tags , on March 5, 2020 by telescoper

It had been on the cards for some time, but last night the airline Flybe collapsed and has now gone into administration. Let me just leave this Twitter announcement made in January by Transport Secretary Grant Shapps here:

It seems that Flybe has gone the inevitable way of every Tory promise.

I had bought a ticket to fly from Dublin to Cardiff at the end of next week as the following week is a study break that includes the St Patrick’s Day holiday. As a result I got this email this morning.

Obviously it’s an inconvenience for me as I’ll have to find another way to get to Cardiff, but I’ll probably get my money refunded by the Chargeback scheme so it’s not such a big deal. The same can’t be said of the 2000 people who worked for Flybe who have now lost their jobs, nor the many others whose livelihoods depended indirectly on this airline who may also lose theirs. The impact on some of the smaller regional airports in the UK will be considerable, although some airlines may well step in and take up some of the demand.

As of last year, almost 80% of flights from Belfast City airport and 95% from Southampton were via Flybe

I think another airline might well take up some of the Belfast routes, but I doubt if the same would be true of Southampton. In a way, it’s a pity that these small mainland regional airports are so important, which is partly because regional train services are so poor and so expensive, but I can’t see that changing.

I have actually used Flybe quite a lot over the last couple of years. For a while I was taking weekly flights between Cardiff and Dublin and the service was generally quite reliable. I feel very sorry for the staff who have lost their jobs and send them my best wishes and hope that they can find alternative employment before too long.
