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.
Gold or Green?

Posted in Biographical, Cardiff, Open Access with tags Bristol Airport, Bristol Temple Meads, Cardiff, Open Access, The Open Journal of Astrophysics on November 1, 2023 by telescoperI 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 El Espectro, Samhain on October 31, 2023 by telescoperSo 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 History, ireland, Modern History 1600 - 1972, R. F. Foster, Roy Foster on October 30, 2023 by telescoperMy 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 Cosmology, Early Release Observations, EROs, Euclid on October 30, 2023 by telescoperJust 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.
The Rugby World Cup Final
Posted in Rugby with tags Rugby World Cup, Rugby World Cup Final, South Africa on October 28, 2023 by telescoperSo, 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 Ruby Braff, Stardust on October 28, 2023 by telescoperRueben “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.
