A 25th Birthday Celebration

Posted in History, Maynooth with tags , , , on June 16, 2022 by telescoper

Today saw a celebratory barbecue on campus to commemorate 25 years of the creation of the National University of Ireland Maynooth now known as Maynooth University, my current employer, as an independent university. The institution was set up as the result of the Universities Act 1997 which was signed into law in May 1997 and came into operation on 16th June 1997 – i.e. 25 years ago today – as a result of the subsequent Commencement Order.

I was unable to attend the event on campus today to celebrate this anniversary because of pressure of work. With a €13.2 million surplus to spend on it, the party was probably very good, but I know I’m not alone among my colleagues in finding little to celebrate in our present predicament of inadequate resources, staff shortages and overwork.

Bloomsday 2022

Posted in Biographical, Literature with tags , , , , on June 16, 2022 by telescoper

So it’s 16th June, a very special day in Ireland – and especially Dublin – because 16th June 1904 is the date on which the story takes place of Ulysses by James Joyce. Bloomsday – named after the character Leopold Bloom – is an annual celebration not only of all things Joycean but also of Ireland’s wider cultural and literary heritage. This year the Bloomsday Festival marks the centenary of the first publication of the complete Ulysses in Paris; it had been published in instalments before that but 2022 was when the full novel was published.

Here is a little video produced by the Irish Foreign Ministry spreading the impact of Bloomsday around the world:

This is also the first time for a few years that Bloomsday events have been held in person. I was toying with the idea of going into Dublin and wandering about some of the locations described in Ulysses, but I have too much work to do. One day I should try to write a paraody of Ulysses about a day in the life of a man who doesn’t go anywhere or do anything except spend the whole day on Microsoft Teams while real life passes him by.

If time permits, however, I will go out and buy the ingredients for a Gorgonzola and mustard sandwich, although unfortunately I shall have to forego the glass of Burgundy that Mr Bloom had with his.

Update: I tried the Gorgonzola and mustard sandwich. It’s an interesting (!) taste, but I don’t think I want to taste it again.

If you haven’t read Ulysses yet then you definitely should. It’s one of the great works of modern literature. And don’t let people put you off by telling you that it’s a difficult read. It really isn’t. It’s a long read that’s for sure -it’s over 900 pages – but the writing is full of colour and energy and it has a real sense of place. It’s a wonderful book.

(There’s also quite a lot of sex in it….)

Planning Research

Posted in Education, Maynooth on June 15, 2022 by telescoper

This summer I have two undergraduate students doing research projects with me funded under Maynooth University’s Summer Programme for Undergraduate Research (SPUR). They’re actually making Monte Carlo simulations of galaxy clustering and using them to test various statistical analysis tools. The Department of Theoretical Physics actually has five students on three different projects, which is quite a lot for a small Department. The University as a whole has 57 SPUR students so we have almost ten percent of the total!

The SPUR students are paid for the projects, which last for (usually) six weeks but can be extended. I wish we could offer these projects to every student who wanted one, actually, but we just can’t afford to do that. I don’t agree with unpaid internships as these can only be taken up by students who have access to enough income to cover living expenses over the summer, so are discriminatory. We select students based on an application and their academic performance.

Anyway, at the start of the SPUR programme students attend a briefing session (which was last Wednesday) and they have to do various tasks along the way and, at the end, construct a poster. At the beginning they have to complete an agreement and “work plan”.

I was very amused to see the following template for a research plan in the pack given to students:

I’m at a loss to understand how any of this relates to how research is actually done in theoretical physics. The many amused reactions from colleagues when I posted this on Twitter yesterday suggest I’m not the only one. As a matter of fact, I don’t understand what many of the buzzphrases even mean. What for example are “As-is process flows”?

Obviously this template is intended for students doing business management courses in which they presumably learn to speak this language. Fortunately this is Template 3 and Template 1 just consists of a list of tasks to be done with key “deliverables” of the sort you need to complete when applying for a research grant, so my students used that.

I find it uncomfortable making detailed plans because to me the whole point of doing research is that you find things out that you didn’t expect and alter your strategy accordingly. If everything were predictable it would be a very dull project. Indeed I would say that if the outcomes were entirely predictable it wouldn’t even deserve the name “research”. Much theoretical research is accordingly rather open-ended, unlike say engineering or product design. On the other hand “give me the money and I hope to discover something interesting” is unlikely to go down well with funding panels. So you have to find a middle ground between convincing the panel that you know what you’re doing and allowing yourself space to adapt in the light of new developments. I think grant bodies in science largely understand that. Or at least I hope they do.

I had better end there as it is time for me to GO-LIVE (sic).

Old School, Old Home

Posted in Biographical, History, Television with tags , , , , , on June 14, 2022 by telescoper

I’ve posted a few times posted about Benwell,  the part of Newcastle in which I grew up. For example I’ve posted about the little house where my first memories live here, and there’s an old photograph of it here:

The house itself (ours was the one on the left on this picture) was built of brick but to the left hand side you can just see a stone wall. The two cottages were demolished some time ago, along with Pendower School which was behind them as viewed from the picture.

I recently came across a picture of Pendower School taken sometime in the early 1990s when it was all boarded up and being sold for redevelopment.

The roof area with the fence around actually had a playground on it, used by Pendower Girls’ High school which occupied most of the building. The Infants and Junior schools which I attended were contained in the wing on the far right of the picture, the Infants downstairs and the Juniors upstairs. The school was built in 1929 and closed in 1992. It was used as a store for some time and then demolished.

The whole area including the school and the old cottages has now been covered with new houses, but for some reason they left the stone wall, part of which you can see to the left of the two cottages of the first picture. These were both taken from Ferguson’s Lane, which is immediately behind the stone wall to the left of the old photograph.

In the second picture you can see the filled in outlines of the door which led to our backyard (on the right) and (on the left) the holes through which the coalman used to deliver the coal that was the only form of heating in the house. There was no central heating and no heating at all upstairs, incidentally, so we had very cold bedrooms in winter!

Anyway, my excuse for reposting this trip down Ferguson’s Memory Lane is that I recently came across this fascinating picture taken from the West in 1897 of the old Benwell Village:

 

I had never seen this picture before but I am now quite sure from looking at street maps of the time that the houses you can see at the far left are in fact the cottages shown in the very first picture of this blog, including the one I lived in! I had never thought about it before, but notice how close the roofline is to the top of the first floor windows. Note also the wall separating them from the rest of the row as they were originally on a private estate.  In the background you can see Benwell Towers which, many years later, is where the TV series Byker Grove was filmed.

The row of houses you can see includes two pubs: The Hawthorn and The Green Tree. Both pubs survived in name though the newer premises were on opposite sides of the road when I lived there. These houses and pubs were all demolished long before I was born to make way for a road (Fox & Hounds Lane) which is basically continuation of Ferguson’s Lane but curving to the left.

A slightly better view from the early 1900s again shows the cottages on the far right. If you click to expand it you can see the drainpipe coming down the front of the house beside the first set of windows, exactly as in the first image on this blog.

Here’s a slightly different view of the same area, taken in 1920 and showing both sides of Ferguson’s Lane, again with Benwell Towers in the distance.

The lamppost is very useful for orienting these three images!

The cottages on the right no longer existed by the time I lived in Benwell: the new Hawthorn Inn stood at their location. At the far end of that row of houses was the old Smithy part of which became a dodgy garage called HQ Motors, which when I lived in the area was guarded by a very scary dog called Patch.

I never really knew what the old Benwell Village looked like. Now I have a much better idea, despite the fact the School the cottages and the pubs have now all vanished!

Gaia’s Third Data Release!

Posted in The Universe and Stuff with tags , , on June 13, 2022 by telescoper

It seems like only yesterday that I blogged about the second release of data from the European Space Agency’s Gaia mission but today sees the release of the third data set, known to its friends as DR3. This completes the set after some initial data were released early as EDR3 back in 2020.

Gaia on the Launchpad at Kourou, French Guyana, on 13th December 2013

In case you weren’t aware, Gaia, launched way back in 2013, is an ambitious space mission to chart a three-dimensional map of our Galaxy, the Milky Way, in the process revealing the composition, formation and evolution of the Galaxy. Gaia will provide unprecedented positional and radial velocity measurements with the accuracy needed to produce a stereoscopic and kinematic census of about one billion stars in our Galaxy and throughout the Local Group. This amounts to about 1 per cent of the Galactic stellar population.

Gaia is likely to operate until round about November 2024, so there’s a lot of data yet to come.

You can find a complete list of what is in DR3 here and if you want to go straight into the papers based on this dataset, go here. There is a nice promotional video here:

R.I.P. Phil Bennett (1948-2022)

Posted in Biographical, Rugby with tags , , , on June 13, 2022 by telescoper

With the passing of Phil Bennett at the age of 73, one of the true greats of Rugby Union has left us. Known to many as “Benny”, Phil Bennett was one of the best players ever to play at fly half for any team at any time. While the role of outside half in the modern game involves a much greater emphasis on kicking ability, Bennett just loved to run with the ball and had an amazing box of tricks with which to bamboozle the opposition, including but not limited to his famous sidestep.

Watch him here in the classic Barbarians versus New Zealand match in Cardiff 1973. The coach of a mere mortal would tear his hair out seeing a player what Bennett did under the shadow of his own posts, but he didn’t just get away with it – he started the move that created a part of Rugby history.

Phil Bennett took over as outside half for Wales from Barry John, who retired early from Rugby, and soon established himself as a permanent member of the phenomenal Welsh team of the early 1970s, joining the ranks of such legends as JPR Williams, Gerald Davies, and Gareth Edwards.

I was born in England but had family connections to Scotland, Wales and Ireland too. Partly because the English team of that period was not strong we always cheered for Wales when we watched the Five Nations games at home. Years later I managed to meet a few of the players of that time. I was flabbergasted to bump into JPR Williams once just outside my house; met Gerald Davies at an event in Cardiff Bay; and encountered Phil Bennett in a bookshop in Cardiff city centre. On all occasions I was completely tongue-tied, struck by the awe of being in the company of such people. All of them were modest and gracious. Remember that Rugby Union in those days was an amateur sport and none of these extraordinary men became rich like modern players do.

Anyway, here is another sensational try featuring Phil Bennett who both starts and finishes the move – with a fantastic contribution from Gerald Davies in between. In the words of the great Bill McLaren “That was absolute magic, and the whole crowd here knows it”.

Rest in Peace, Phil Bennett (1948-2022)

John McLaughlin

Posted in Jazz with tags , , on June 12, 2022 by telescoper

It’s Sunday and I’ve just finished work for the day. Too tired to write anything substantial I thought I’d share a track featuring and named after the guitarist I went to see at the National Concert Hall a few weeks ago. John McLaughlin is the 4th track on the Miles Davis (double) album Bitches Brew. It doesn’t feature Miles Davis on trumpet nor Wayne Shorter on saxophone but does involve the electric pianos of Chick Corea and Joe Zawinul, the bass of Dave Holland, the drums of Lenny White and Jack de Johnette, other percussion by Don Alias and Juma Santos and Bennie Maupin on bass clarinet; the latter addition to the ensemble being a stroke of genius by Miles Davis. I know quite a lot of fans of Miles Davis don’t like this album at all, finding it all a bit perplexing but I don’t mind music that’s a bit perplexing and I think it’s great. Most of the tracks are very long but this one is only four and a half minutes or so in duration, built around a simple riff laid over a loose and very dynamic rhythmic accompaniment. Like the other numbers, it’s almost entirely improvised.

A Leaving Certificate Applied Maths Problem

Posted in Cute Problems, Education, mathematics with tags , on June 11, 2022 by telescoper

The 2022 cycle of Leaving Certificate examinations is under way and the first Mathematics (Ordinary and Higher) were yesterday there’s been the usual discussion about whether they are easier or harder than in the past. I won’t get involved in this except to point you to this interesting discussion based on an archive of mathematics questions, that this year the papers have more choice for students and that, apparently, the first Higher Mathematics paper had very little calculus on it.

Anyway, I was looking through some old Applied Mathematics Leaving Certificate papers, as these cover some similar ground to our first year Mathematical Physics at Maynooth, and my eye was drawn to this question from 2010 about two balls jammed in a cylinder…

I’d add another: does it matter whether or not the cylinder is smooth (as this is not specified in the question)?

Concerning Covid Immunity

Posted in Biographical, Covid-19, Maynooth with tags , , , on June 10, 2022 by telescoper

Over the past few weeks I’ve attended a number of events at which most people were not wearing face coverings, including a recent Open Day at which I took my mask off in order to be heard in a very crowded space. Although I still wear a mask on public transport and in shops, most people now do not.

The first thing I’d note is that that there has been a clear upturn in reported Covid-19 cases, with figures now running at about 700 per day:

(Official figures for Ireland are only issued weekly these days…)

It’s not an alarming increase but hospitalizations and testing positivity are also increasing, though the mortality rate remains low because of the protection afforded by vaccines. Incidentally, it was a year ago on Wednesday (8th June) that I received my second Pfizer dose. One wonders how long vaccine protection will last, though, until further boosters are needed. If cases continue to rise I wonder if any measures will be put in place before the start of next academic year?

A number of my colleagues at home and abroad have attended scientific conferences recently, a number of which have led to mini-outbreaks and some instances of quite serious illness. Although most people seem to think Covid has gone away, it clearly hasn’t. A resurgence is all we need right now.

Anyway, one of my colleagues at work expressed surprise that I didn’t catch Covid during the largely unmasked Open Day at the end of April. Of course I might have done but I certainly didn’t display any symptoms. I’ve actually been quite surprised that I have never shown any sign of SARS-Cov2 at all during the entire period of the pandemic, while many of my colleagues and students in the Department have come down with it.

Coincidentally, a comment appeared yesterday on a blog post I wrote a while ago in which I revealed that I have the  CCR5-Δ32 genetic mutation which confers protection against HIV infection. As a matter of fact I have it twice (i.e. homozygotic). For one thing the commenter pointed out that this mutation may have protected against smallpox, which means some evolutionary selection may have been involved in its propagation. The commenter also drew attention to the evidence – by no means conclusive at this stage – that this mutation may also protect against Covid-19. If you’re interested here are links to some papers:

The last of these is a preprint but the other two are peer-reviewed publications.

Could it be that I’ve yet again been a jammy bastard and inherited immunity to Covid-19 too?

R.I.P. David Hughes (1941-2022)

David W Hughes (1941-2022)

I am once again very sorry to have to pass on some sad news. Astronomer David Hughes (formerly of Sheffield University) passed away suddenly on Monday 6th June at the age of 80.

Born in Nottinghamshire, David did his first degree at Birmingham University and his DPhil in Oxford. He moved to Sheffield in 1965 and worked there until he retired in 2007.

David was an expert on the Solar System, especially its minor bodies, such as asteroids and comets; the Mars-crossing asteroid 4205 David Hughes is named in honour of his many achievements. He was also very knowledgeable about the history of astronomy and the threat to Earth from meteors and other impact phenomena. An ebullient public speaker, he was much in demand as a guest on TV programmes, as well as giving lectures on cruise ships and talks to amateur astronomical societies and lay audiences. Through these activities he did a huge amount for the popularization of astronomy especially in the UK.

I send my condolences to his family, friends and colleagues both in Sheffield and around the world.

R.I.P. David W Hughes (1941-2022)
