Nollaig Shona

Posted in Maynooth on December 19, 2019 by telescoper

Well, workwise, that’s me just about done for the year 2019.

I received the `official’ Christmas card shown above from the President of the Maynooth University, Professor Philip Nolan, earlier this week so I thought I’d share the picture as a Christmas card to my readers (both of them). The phrase on the card means `Happy Christmas’ (though, as the Welsh `Nadolig Llawen’, the Happy comes after the Christmas). Sometimes you find the phrase Nollaig Shona Duit which means `Happy Christmas to you’.

There’s quite a similarity between the Irish word for Christmas, Nollaig, and the Welsh word Nadolig. That’s not surprising because we are talking about two Celtic languages. But are both related in some way to Noel?

End of Teaching for 2019

Posted in Biographical, Education, Maynooth on December 18, 2019 by telescoper

So it’s 6pm on Wednesday 18th December and I’ve just given my 24th and last Astrophysics & Cosmology lecture for the term at Maynooth University. Earlier this afternoon I gave my 36th and last first-year Mechanics & Special Relativity module so that’s over for the year too. That makes 60 lectures for the semester.

I find these twelve week semesters very tiring (even with a week-long break in the middle). I assume the students do too. Numbers in class certainly dropped off this week, but overall I’ve been very happy with the level of engagement of the students, especially the first years. Although it’s a lot of work putting on a big course for the first time, I do enjoy teaching very much indeed. I have found few things in life more rewarding than teaching students who want to learn and physics students here in Maynooth do seem to be highly motivated. The exams for both modules are in January so I’ll find out in the New Year if anyone actually learnt anything!

This morning somebody suggested that would be my last teaching for the decade. Of course that is incorrect. The current decade ends on 31st December 2020, not 31st December 2019, just as the millennium started on 1st January 2001 not 1st January 2000. I’m glad a fellow blogger has taken the trouble to point the reason: there is no Year Zero.

Earlier today we had presentations from our final-year project students, which were very good. As usual on such occasions I find myself thinking how much better current generations of students are at that than mine was!

I don’t mind admitting that I’m not inconsiderably knackered at this moment and will be heading home for a bite to eat and a glass or several of wine. Tomorrow I have a few things to do before heading off for the Christmas break, after which regular blogging will be suspended for a time.

 

The ties that bind..

Posted in Uncategorized with tags , , , , , on December 17, 2019 by telescoper

The other day I saw a post on Facebook from an American friend which referred to the wearing of a `necktie’. I’ve always been confused by this word, largely because I’m not aware of many other examples of words combining an item of clothing with where it is worn on the body. As far as I am aware neither `headhat’ nor `footsock’ nor `legtrousers’ is a word. Presumably the prefix `neck-‘ is added to `tie’ in order to specify where the tie is to be worn, either because the wearer might not otherwise know or because there are different kinds of tie to be worn elsewhere on the body as is the case, for example, with `cockring’.

But where else would one wear a tie other than around one’s neck?

Thinking about this problem led me to the related issue of why (hopefully) soon-to-be-former President of the United States of America, Donald Trump wears such long (neck)ties:

I believe I have an answer to both puzzles. Trump wears an extra-long tie because it’s actually a bellytie, meant to be worn around the waist to keep the legtrousers from falling down. It needs to be extra long because Donald Trump is excessively corpulent. Obviously he only puts his bellytie around his neck when in public, and has some other arrangement to keep his legtrousers up in that situation. I suspect he might wear suspenders.

You may find this all a bit trivial but I post it here for the benefit of British readers whose country will soon be forced to grovel at Trump’s feet for the luxury of being allowed to import chlorinated chicken from America and to be charged higher prices for prescription medicine. You will need to learn the proper vocabulary pronto if you want to fit in with the new order of things.

Change in Northern Ireland

Posted in History, Politics with tags , , on December 17, 2019 by telescoper

One of the potentially most significant outcomes of the 2019 General Election, but one barely mentioned in the English media, was what happened in Northern Ireland. For the first time ever, a majority of the MPs elected in the six counties were nationalist. The Social Democratic and Labour Party (SDLP) gained two seats to add to the seven of Sinn Féin (including a significant gain in Belfast North) while the Democratic Unionist Party (DUP) lost two to finish with eight. The remaining seat went to the Alliance, originally a moderate unionist party but now basically a liberal centrist (and anti-Brexit) party.

Here’s how the electoral map of Northern Ireland changed:

Sinn Féin seats are dark green, DUP orange, SDLP light green and Alliance yellow.

In terms of the popular vote, the DUP+UUP got 42.3% whereas SDLP+ Sinn Féin got 37.7. Both SF and DUP lost vote share compared to 2017 (by 6.7% and 5.4% respectively) at the expense of the Alliance (up 8.8%) and SDLP (up 3.1%).

Incremental differences, perhaps, but significant nonetheless – especially as Brexit hasn’t yet happened. After Brexit there will be a border in the Irish Sea, which will bring the end of partition one step closer. The probability of seeing a United Ireland in my lifetime has definitely increased.

It was no surprise to see the hashtag `#UnityPlan’ trending on Twitter immediately after the election. Irish unification will only happen if there is a public vote and a majority on both sides of the border agree. For that vote to be fair it is vital that there is a definite plan on how to proceed in the event that the vote is in favour, so the public know what they are voting for. The Irish should not make the mistake that Britain did over Brexit.

For many unionists religion was the primary reason for wanting to remain in the United Kingdom at the time of partition in 1921: Protestants felt that their identity would be threatened if they were made to join the Catholic South. Maybe they were right to feel nervous, as the original constitution of the Irish Free State enshrined “the special position of the Holy Catholic Apostolic and Roman Church”.  But the section including that phrase was deltd from the Constitution way back in 1973 and the Roman Church has far less influence in the Republic than it did. Ireland is now an open and progressive country, so I hope those fears have receded.

Just to confuse matters even further I should mention that my Grandfather, the one born in Belfast, to whom I owe my Irish citizenship,  was a protestant republican…

Those in the North who wish to keep their British passports should be able to do so in a United Ireland, just as those of us who were born in Britain but now live in Ireland can keep ours. I’ll be keeping mine, at least until it expires…

P.S. It is worth mentioning (primarily for British friends) that there are three counties in Ireland that belong to the province of Ulster but are not part of Northern Ireland as it was formed after partition: these are Monaghan, Cavan and Donegal. The northernmost point of Donegal, Malin Head, is actually the northernmost point on the island of Ireland.

Those `Former Mining Communities’

Posted in Biographical, History, Politics with tags , , , , , , , on December 15, 2019 by telescoper

I’ve generally avoided the UK media over the last few days but couldn’t resist commenting on a phrase that has appeared again in the context of constituencies in the North and Midlands of England that voted in Tory Members of Parliament in the 2019 General Election.

The first of these to declare a result was Blyth Valley, in Northumberland, a place that I know reasonably well as I grew up in the North-East. This constituency was created in 1955 and had a Labour MP continuously from then until December 12th 2019.

(Incidentally, the winning candidate in Blyth Valley, Ian Levy, presented himself as an NHS nurse, which he has never been. I doubt anyone cares, though. Bare-faced lying seems to be completely acceptable these days.)

(Left) Bates Colliery in Blyth in 1986 when it closed; (Right) the scene in 2014. Picture Credit Newcastle Evening Chronicle.

I should state for the record that I was born in Walker, to the East of Newcastle upon Tyne, but grew up in Benwell, to the West. When I was a child all the pits in the immediate vicinity, such as the Montague Main Colliery in Denton Burn, had already closed because the inland coal seams had been exhausted. Those remaining open were deep mines in which the coal faces were out under the North Sea.

Anyway, Blyth Valley was described in the media after the election result as a `Former Mining Community’. The town of Blyth is a port and was at one time a major centre for shipbuilding as well as coal mining, but the coal industry –especially Bates colliery – was indeed an extremely important factor in the town’s economy.

But Bates Colliery closed in 1986. A bit further inland the larger, and probably more famous, Ashington Colliery closed in 1988. The last mine in the North West Durham coalfield closed in 1994. Further South, Bolsover Colliery (in the Derbyshire constituency by Dennis Skinner for 49 years, until December 12th 2019) closed in 1993. And so on. All these places, and many others. decided to return Conservative MPs in 2019.

None of these places has had a working coal pit for 25 years or more, yet they are still consistently described in the media as `former mining communities’. I find that very telling, when there hasn’t been any mining there for a generation.

Coal mining forged the identity of these places. Almost everything revolved around the pits. Many of the houses were specifically by colliery owners to house the miners and their families. In the North-East, miners even had their own dialect, Pitmatic (distinct from Geordie). It wasn’t by any means an easy life being a miner but to be a miner at least meant having a distinct and proud identity,

The foundations of these communities were taken away during the Thatcher years. It’s not just about the local economic devastation, though that was bad enough, it was that the entire raison d’être disappeared. Over the subsequent decades little effort has been made by any Government of any complexion to stimulate the towns and villages so they remain `former mining communities’. Their past is well-defined, their future not.

After a decade of particularly severe austerity it’s hardly surprising that people in such areas expressed their anger at a political system that has failed them so badly, first in the 2016 referendum and then in this year’s General Election.

What’s less comprehensible (at least to me) is why anyone would think that their situation is likely to improve under the same Tories that have ignored them so consistently for so long. All I can guess is that it’s something to do with finding a sense of identity in a mining community that’s no longer a mining community. I suppose that, for some, this entails adopting increasingly nationalistic attitudes, such as were encouraged by the Conservative Party’s consistently xenophobic and anti-immigrant rhetoric.

For myself I don’t see what identity has to do with nationality at all. We can identify ourselves in all kinds of ways without having to rely on the geographical accident of our birthplace.

I have no idea what the next five years will bring for places like Blyth Valley and Bolsover. But the wider question is whether by the time of the next General Election we will will be talking about the former United Kingdom.

Britain’s Potential Explained

Posted in Politics, The Universe and Stuff with tags , , , on December 14, 2019 by telescoper

As a physicist I was intrigued by the recent use by Tory election campaigners of the slogan “Unleash Britain’s Potential”, so I decided to study the matter in more detail. I am pleased to say I am now ready to report on my conclusions.

First here is a sketch of Britain’s potential, which I denote V(r):

How do we interpret this potential?

Recall that the force F(r) derived from V(r) is given by

F(r) = - \frac{dV(r)}{dr}.

The gradient of this potential being negative the force is directed towards increasing values of r. By Newton’s Second Law this means accelerated motion to the right (i.e. in the direction of increasing isolation), accompanied by steady and irreversible decline.

Note also that the form of this potential implies that there is something completely repulsive at its origin.

I hope this clarifies the situation.

Britain dutifully bows down to the ruling elite.

A view from New Zealand…

leftinnewzealand's avatarLeft in New Zealand

Congratulations to the people of ‘Great’ Britain for voting the ruling elite into power yet again. You certainly do know your place. Now they have a mandate to treat people with disdain and contempt, for the next five years. I always thought people in the US were dumb, but there is a new kid on the block vying for the title. How can a party offering no credible policies, with a history of inflicting misery on millions, with a leader who hides in a fridge when things get mildly difficult remain in power. I could glibly say you get what you deserve, but that would be grossly unfair to the millions who can see through this charade of thinly veiled fascism.

It would appear that many people from where I grew up in the north have had a lobotomy, believing all that the billionaire controlled media had to say pre-election…

Goodbye UK

Posted in Biographical, Politics, Uncategorized on December 13, 2019 by telescoper

Britain’s Prime Charlatan

Here I am on a Late Great Western train heading to this month’s Meeting of the Royal Astronomical Society in London and to pass the time I thought I’d have a go on the blog.

I’m not going to comment at length of the election results, except to say that the scale of the Conservative majority and corresponding Labour rout mean that the UK is heading for at least five years with the hard right in charge, and probably many more. That is if the United Kingdom exists five years from now, which is doubtful.

During this time the country of my birth will almost certainly turn itself into a Trumpian dystopia, with planned assaults on the National Health Service, the courts, and what remains of its threadbare constitution. Poverty and homelessness will continue to rise and the evil xenophobic rhetoric that helped win the election (as it did the 2016 Referendum) will make the environment of the UK even more hostile to anyone ‘foreign’.

That’s whats going to happen and that, apparently, is what people voted for. How anyone could vote for a party led by a person so palpably unsuitable for high office is beyond me. But that’s what people did. I hope they’re proud.

For myself, I’ll just say two things. One is that at least this Election Night made me feel young again. I relived all the horror of 1983.

The second is just that although Ireland is no paradise I’m glad I found a way out of the nightmare of Britain. Sorry if that sounds selfish but it’s the truth.

Goodbye UK.

P.S. My train is going to be at least an hour late. No chance of the railways being fixed in the next five years either.

Don’t mind me, I’m honing my toning

Posted in Biographical with tags , on December 12, 2019 by telescoper

Trying to divert myself from thoughts of what the British electorate is about to do, I actually read one of the emails I get from WordPress. I found this:

 

I suddenly realized that I’ve been doing the blogging all wrong for the past 11 years. I should have been trying to cultivate and convey my online personality in order to humanize my brand as well establishing an emotional relationship with, and gaining the trust of, my visitors.

I’m by no means convinced that any of my visitors would want to have an emotional relationship with me, but I promise to try harder in future to hone my tone.

Even if I do all this, however, I still think I’ll struggle to achieve business growth, principally because I don’t have a business in the first place.
