Gold or Green?

Posted in Open Access, Television with tags , , , on November 2, 2023 by telescoper

During my talk yesterday I mentioned the difference between “Green” and “Gold” forms of Open Access, which always makes me think of a scene from Blackadder II. I mentioned this in the talk and it seems not everyone in the audience was aware of the cultural reference, so here is the clip in question. It doesn’t have anything to do with Open Access, of course, but I think it is very funny.

The 21 Group – Update

Posted in Harassment Bullying etc with tags , , , on November 2, 2023 by telescoper

You may have read last week (26th October) a guest post on this blog by Wyn Evans about the launch of the 21Group:

Following this post, the launch of this group has now been covered by the Times Higher

https://www.timeshighereducation.com/news/bullying-support-network-launched-due-universities-inaction

and Nature

https://www.nature.com/articles/d41586-023-03418-3

I’ll update this post with further relevant links if and when I find them; you can also follow the campaign on the 21Group blog.

I very much hope this initiative succeeds in its aims, though it has powerful reactionary forces arrayed against it.

In other news, I’m told that the University of Manchester has blocked access to the 21group website by staff through centrally-managed devices. This may be inadvertent, but if it’s deliberate then it is both sinister and stupid.

Flying visit to Cardiff

Posted in Biographical, Cardiff, Open Access with tags , , , , on November 1, 2023 by telescoper

I got up at 3am this morning to take a bus to an airport, then a flight to Bristol Airport, then another bus to Bristol Temple Meads, and then a train to Cardiff in order to give a seminar. Now I’m in the middle of the reverse process, having a pint in Bristol Airport.

In case you’re thinking of using Bristol Airport at any time in the next 8 weeks, then please bear in mind that there are major roadworks on the approach road, so be sure to allow extra time. It took over an hour from Bristol Temple Meads this evening, more than double the usual time, and it’s only 8 miles…

I’m more than a little tired after all that, but it was still very nice to meet up with friends and former colleagues again. I was particularly delighted to learn that Professor Haley Gomez has been appointed Head of the School of Physics and Astronomy. Congratulations to Haley!

I’ll upload the slides from my talk when I get back to base. For the time being, however, I’m just going to chill in the departure lounge before my return flight.

Update: the return leg ran to schedule so here, as promised, are the slides for the talk I was invited to give:

P.S. I’ll be giving two talks on the same theme later this month in different institutes in France.

On Samhain

Posted in Biographical with tags , on October 31, 2023 by telescoper

So we have arrived at October 31st, Hallowe’en or, in pagan terms, Samhain. This, a cross-quarter day – roughly halfway between the Autumnal Equinox and the Winter Solstice – represents the start of winter (“the dark half of the year“) in the Celtic calendar. Technically, Samhain is tomorrow, 1st November, but the Celtic practice of reckoning days from sunset to sunset makes this a moot point.

Samhain is pronounced something like “sowin”. The h after the m denotes lenition of the consonant (which in older forms of Irish would have been denoted by a dot on top of the m) so when followed by a broad vowel the m is pronounced like the English “w”; when followed by a slender vowel or none “mh” is pronounced “v” or in other words like the German “w” (which makes it easier to remember). The phrase Oíche Shamhna (the Eve of Samhain) is used for Hallowe’en; it contains the genitive form of Samhain.

Anyway, as it was foretold, I am not in Barcelona and will continue to be not-in-Barcelona for a few days. Indeed, tomorrow, if all goes to plan, I’ll be in a different part of non-Barcelona. With all that running about I’m a bit busy for a proper blog post so I’ll just take the opportunity to point out that yet another anagram of my name is El Espectro

Oíche Shamhna shona daoibh go léir!

Modern Ireland 1600-1972 by R. F. Foster

Posted in History, Literature with tags , , , , on October 30, 2023 by telescoper

My attempt to catch up with a backlog of reading while on sabbatical has now brought me to Modern Ireland, by R.F. Foster, the paperback version of which, shown above, I bought way back in 2018 but have only just finished reading. In the following I’ll describe the scope of the book and make a few observations.

The book was first published in 1988 so it obviously can’t deal with more recent events such as the Good Friday Agreement. The narrative stops almost 50 years ago in 1972, the year of Bloody Sunday and just before Ireland joined the European Economic Community in 1973, but since it starts way back in 1600 one can forgive Roy Foster for not covering such recent events. The start is in what is usually termed the early modern period, but if truth be told much of Irish society at that point was still organized on mediaeval lines.

To set the scene, Foster starts with a description of the three main sections of the population of Ireland in 1600. These were the (Gaelic and Catholic) Irish, the “Old English”, descendants of the 12th Century conquest of part of the country, who were also Catholic, and the Protestant “New English” who arrived with the Tudor plantations. There were tensions between all three of these groups.

The rest of the book is divided into four parts, roughly one per century: Part I covers the continued Elizabethan plantation of Ireland, rebellions against it, the devastation caused by Cromwell’s so-called “pacification”, and the Penal Laws that basically outlawed the Catholic faith. In Part II Foster discusses a period often called The Ascendancy which showed the consolidation of power in the hands of a Protestant – specifically Anglican – ruling class, though there was a sizeable community of non-conformist Protestants, chiefly Presbyterians, who were regarded by Anglicans with almost as much suspicion as the Catholics. This Part ends with yet another failed rebellion, involving Wolfe Tone and the United Irishmen, against the backdrop of the French revolution. Up until the Act of Union of 1800, Ireland had its own Parliament; after that Irish MPs were sent to the House of Commons in Westminster. The century covered by Part III includes the Irish Famine, rising levels of rural violence, and issues of land reform, and various attempts to deliver some form of Home Rule; it ends with Charles Stewart Parnell. Part IV covers the Easter Rising, War of Independence, Civil War, Partition, the creation of the Irish Free State, and the eventual formation of the Irish Republic. A running theme through all four Parts is a recognition of how historical forces – and not only religion – shaped Ulster in a different way from the rest of Ireland.

As I’ve said before on this blog, it disturbs me quite how little of this history I was taught at school in England so I found it valuable to read a detailed scholarly work whose main message is that everything is much more complex than simple narratives – those peddled by politicians, for example – would have you believe. This is primarily a revisionist history, calling much of received wisdom into question. That said, it’s probably not the best book for a newcomer to Irish history. Foster does assume knowledge of quite a few of the major events and, while reading it, I did have to look quite a few things up. Much is said in the jacket reviews of the author’s writing style. To be honest, I found it sometimes rather mannered and self-conscious, though with some enjoyably arch humour thrown in for good measure. It’s thoroughly researched, as far as that is possible when primary sources are sketchy and contemporary records usually written by someone with an axe to grind. It does seem to rely mainly on documents written in English, however, so one might argue that introduces quite a bias. I gather that there is much greater emphasis among contemporary Irish historians on records written in Irish (Gaelic).

The book is rather heavy on footnotes, too. Usually I dislike these, but in this case they are mostly little biographical sketches of important figures which would have disrupted the flow if included in the main text, and I found many of them valuable. Just to be perverse, I have to say I liked his liberal use of semicolons. Though dense, the books is as accessible as I think a scholarly work can be and although I am not so much a scholar of history as an interested bystander, I learnt a lot. It also made me want to learn more, especially about the period between the death of Parnell in 1891 and the Easter Rising of 1916.

It seems apt to finish with an excerpt that illustrates a theme that crops up repeatedly during the 23 chapters of the book:

Irish history in the long period since the completion of the Elizabethan conquest concerned a great deal more than the definition of Irishness against Britishness; this survey has attempted to indicate as much. But that sense of difference comes strongly through, though its expression was conditioned by altering circumstances, and adapted for different interest-groups, as the years passed. If the claims of cultural maturity and a new European identity advanced by the 1970s can be substantiated, it may be by the hope of a more relaxed and inclusive definition of Irishness, and a less constricted view of Irish history.

Modern Ireland, R. F. Foster, p596

I hope that too. It may even be happening.

Euclid Update!

Posted in Euclid with tags , , , on October 30, 2023 by telescoper

Just a quick post to give advanced notice that, gremlins in the pointing system having been dispelled, the first actual science images from European Space Agency’s Euclid mission will be released on Tuesday 7th November at 14.00 Central European (not Summer) Time, CET. These are called the Early Release Observations (EROs) – they won’t be part of the full survey, but are just to demonstrate the performance of the telescope and detectors.

You can watch the press conference on the new ESA Web TV channel. I’ll post more about the EROs after they become public, but not before.

It’s That Time Again…

Posted in Barcelona, History with tags , , on October 29, 2023 by telescoper

It’s 29th October 2023, which marks the end of “Summer Time” in Europe. Accordingly, the temperature in Barcelona has plummetted to 22°C. I have to make a flying visit to the UK next week and I suspect that I’m in for a bit of a shock, having adjusted to these balmy climes.  I have numerous telecons next week too and, since  some parts of the world will be still on Daylight Saving Time (or whatever) there’s potential for confusion in the timing.

Some time ago, before the Covid-19 Pandemic, the European Parliament approved a directive that would abolish `Daylight Saving Time’.  Unfortunately that plan has been ‘paused’ and there’s no sign of it happening for the foreseeable future.  I’ve long felt that the annual ritual of putting the clocks forward in the Spring and back again in the Autumn was a waste of time effort, so I’ll be glad when this silly practice is terminated. It would be far better in my view to stick with a single Mean Time throughout the year. I’m only disappointed that this hasn’t happened already.

The marvellous poster above is from 1916, when British Summer Time was introduced. I was surprised to learn recently that the practice of changing clocks backwards and forwards in the UK is only about a hundred years old and was introduced as an emergency measure in wartime. To be honest I’m also surprised that the practice persists to this day, as I can’t see any real advantage in it. Any institution or organisation that really wants to change its working hours in summer can easily do so, but the world of work is far more flexible nowadays than it was a hundred years ago and I think very few would feel the need.

Anyway, while I am on about Mean Time, here is a another poster from 1916.

Until October 1916, clocks in Ireland were set to Dublin Mean Time, as defined at Dunsink Observatory, rather than at Greenwich. The adoption of GMT in Ireland was driven largely by the fact that the British authorities found that the time difference between Dublin and London had confused telegraphic communications during the Easter Rising earlier in 1916. Its imposition was therefore, at least in part, intended to bring Ireland under closer control. This did not go down well with Irish nationalists.

Ireland had not moved to Summer Time with Britain in May 1916 because of the Easter Rising. Dublin Mean Time was 25 minutes 21 seconds behind GMT but the change to GMT was introduced in Ireland at the same time as BST ended in the UK, hence the alteration by one hour minus 25 minutes 21 seconds, i.e. 34 minutes and 39 seconds as in the poster.

Britain will probably never scrap British Summer Time on the grounds that whatever the EU does must necessarily be bad. What will happen to Northern Ireland when Ireland scraps Daylight Saving Time is yet to be seen.

The Rugby World Cup Final

Posted in Rugby with tags , , on October 28, 2023 by telescoper

So, after a tense, scrappy, and error-strewn final, South Africa have retained the Rugby World Cup by beating New Zealand 12-11, all the Springboks’ points coming from penalties kicked by Handré Pollard – shades of the 1995 final, when Joel Stransky kicked all the points for South Africa.

The game hinged on the sending-off of the New Zealand captain Sam Cane in the first half – a decision about which the All Blacks can have no complaints. Despite playing for over 50 minutes with only 14 men, New Zealand had chances to win, specifically the missed conversion of the game’s only try, which would have made it 13-12.

But you can’t blame anyone else if you don’t take your chances, so congratulations to South Africa!

It’s been a strange World Cup, with some cracking games, a fair share of heartbreak (especially for Ireland and France), and an absurdly unbalanced draw. Let’s hope the arrangements for 2027 are thought out better!

Stardust – Ruby Braff

Posted in Jazz with tags , on October 28, 2023 by telescoper

Rueben “Ruby” Braff is probably better known as a cornet player than a trumpeter, but whenever he did play the trumpet he showed why Jack Teagarden dubbed him “the Ivy League Louis Armstrong”. Here’s a gorgeous performance by him of the Hoagy Carmichael classic Stardust in which he wears the influence of Louis Armstrong on his sleeve.

P.S. The pianist on this track is a young Dave McKenna.

Teaching in Base 60

Posted in Barcelona, Cardiff, History, mathematics, Maynooth with tags , , , , on October 27, 2023 by telescoper

Some time ago – was it really over a decade? – I wrote a piece about the optimum size of modules in physics teaching. I was still in the United Kingdom then so my ramblings were based on a framework in which undergraduate students would take 120 credits per year, usually divided into two semesters of 60 credits each. In Cardiff, for instance, most modules were (and still are) 10 credits but some core material was delivered in 20 credit modules. In the case of Sussex, to give a contrasting example, the standard “quantum” of teaching was the 15 credit module. I actually preferred the latter because that would allow the lecturer to go into greater depth, students would be only be studying four modules in a semester (instead of six if the curriculum consisted of 10 credit modules), and there would be fewer examinations. In short, the curriculum would be less “bitty”.

In Maynooth the size of modules is reckoned using the European Credit Transfer System (ECTS) which takes a full year of undergraduate teaching to be 60 credits rather than 120 in the UK, but the conversion between the two is a simple factor of two. In Maynooth the “standard” unit of teaching is 5 credits, with some 10 credit modules thrown in (usually extending over two semesters, e.g. projects). This is similar to the Cardiff system. The exception concerns first-year modules, which are 7.5 credits each because students take four modules in their first year so they have to be 30/4=7.5 credits each. The first year is therefore like the Sussex system. It changes to a five-credit quantum from Year 2 onwards because students do three subjects at that stage.

I find it interesting to compare this with the arrangements here in Barcelona (and elsewhere in Spain). Here the ECTS credit size is used, but the standard module is six credits, not five, and year-long projects here are 12 credits rather than 10. The effect of this is that students generally study five modules at a time (or four plus a project). To add to the fun there are also some 9 credit modules, so a semester could be made up of combinations of 6-credit and 9-credit chunks as long as the total adds up to 30.

Anyway, the main point of all this is to illustrate the joy of the sexagesimal system which derives from the fact that 60, being a superior composite number, has so many integer divisors: 2, 3, 4, 5, 6, 12, 15, 20, and 30. The Babylonians knew a thing or two!
