Easter Time and Sabbaticals
Posted in Biographical, Maynooth with tags sabbatical on April 6, 2023 by telescoperSo it’s Maundy Thursday, i.e. the day before Good Friday, on which we are supposed to wash the feet of our disciples. Not having been issued with any disciples, I’ll have to give that bit a miss and just work as normal for the rest of today.
Tomorrow is a holiday, as is next Monday, Easter Monday. The rest of next week is a study break, a welcome pause before we embark on the rest of term.
There will still be three weeks of teaching before the end of the Semester when we return on 17th April, but I’ve actually done my last lecture in Computational Physics. I’ve taught them all the things they need for the rest of the module. When they get back students will be mainly working in groups on their mini-projects which are due in by 5th May. The other module I teach will carry on as usual until the end of term.
Anyway, the three weeks that have passed between the St Patrick’s Day study break and today have flown by, but at least I’ve kept up to date.
Yesterday I found out that I have been granted a sabbatical for half of next academic year. I had asked for a full year, but that wasn’t agreed, so I now have to decide whether to disappear from August 2023 to January 2024 or from February 2024 to July 2024. I’ve only got the Easter break to decide which option to take, so I’ll have to spend a bit of time trying to work out what to do. I had planned two different trips during a full-year sabbatical. I’ll probably have to drop one of them. I also made plans for my research students, which I’ll have to change. I’m sure I can work something out though.
My two biggest classes are in Semester 1 so I’d probably get more personal benefit from taking the first option, but it might be harder to find a replacement to teach these modules given the shorter notice. It will also be tricky to make the necessary arrangements with potential hosts elsewhere by August, which tends to motivate the second option. I’ll have to think about it.
The last time I had a sabbatical break was in 2005, when I was at the University of Nottingham. That also was just one semester. After an abortive attempt to get a J-1 visa so I could visit the University of California at Berkeley, I ended up going to Toronto, which was very nice, but instead of giving my teaching to someone else for the term I missed, it was just moved to the second semester so I had a double load when I returned. I hope nobody tries that trick this time!
At least this time there won’t be a problem with visas et cetera, as I intend to exploit the freedom of movement I have within the European Union…
A Jazz Centenary
Posted in History, Jazz with tags 1923, Gennett Studios, Jazz, King Oliver, King Oliver's Creole Jazz Band, Louis Armstrong on April 5, 2023 by telescoper
I’ve been looking forward to this day because it marks an important jazz centenary. Or at least I think it does. There’s some contradictory evidence about whether it was April 5th 1923 or April 6th, or maybe both, when King Oliver‘s Creole Jazz Band did its first ever recording session at the Gennett studios in Richmond, Virginia. They recorded 20 sides in that session, which may well have involved two days with a break in between or working through the night.
These dates represent a remarkable occasion not only because King Oliver’s band was really the first jazz Supergroup, but also because it had been joined just a few months earlier by a young cornet player by the name of Louis Armstrong. This session therefore represent the first examples of Louis Armstrong ever heard on record.
It is somewhat surprising that this historic session happened at the Gennett studios. The band was based on Chicago, Illinois, and the studios were in Richmond, Virginia, so it required a long road trip to get there. Moreover the studio building wasn’t exactly in a prime location, as it was right next to a railroad line:

Musicians had to time their recordings so as to avoid the noise from passing trains. Still, records only lasted about 3 minutes in those days so presumably weren’t so frequent as to make it difficult to fit in a take between two of them! Recording techniques were rather primitive in those days though, and the sound quality that emerged isn’t great.
The lineup for the band is shown in the picture at the top of this page. It’s interesting to note that four of these musicians (Armstrong, Hardin, and the Dodds brothers) were to feature regularly from 1925 onwards in the classic Hot Fives and Hot Sevens. King Oliver’s band, however, had style that was very different from these later records, with a much greater emphasis on polyphony, much more complex arrangements, and much less emphasis on solos. Also, King Oliver’s band played to live audiences on a regular basis, but the Hot Fives and Hot Seven only ever performed as such in recording studios.
As far as I understand how this band worked, King Oliver made the arrangements. I don’t think they used full written scores, but tended to play from wonderfully intricate “head arrangements” worked out beforehand, with ensemble passages, gaps for breaks and solos, and King Oliver introducing the (usually very catchy themes). Armstrong and Johnny Dodds improvised a decorative counterpoint, and Honore Dutrey added harmonic breadth to the ensemble. This must have been a great learning experience for the young Louis Armstrong, has he had to develop a great ear for what was going on around him to play like this. I gather that Louis Armstrong often tended to play very loud so he was kept well in the background in these early Gennett sessions, but such a prodigious talent was never going to play second fiddle for long and in later sessions he effectively duets with King Oliver and swapped leads with him freely and completely intuitively, producing a sound that was entirely unique. I am always astonished by how much is going on in these old records, even if you can’t hear it all very well!
I’ve mentioned before that, over time, this classic type of polyphonic Jazz – derived from its New Orleans roots – gradually morphed into musical form dominated by much simpler arrangements and a succession of virtuoso solos. This change was also reflected in the differing fortunes of Louis Armstrong and King Oliver. The former went on to become an international celebrity, while the latter lost all his savings when his bank went bust during the Wall Street Crash and ended his life working as a janitor.
As well as Gennett, this band recorded with other labels in 1923 including Okeh and Columbia. Sadly however they split up at the end of 1923 over disagreements about a possible tour in 1924. Only about 40 sides were ever recorded King Oliver’s Creole Jazz Band. Many of them are absolutely marvelous.
This is the first track recorded by the band in April 1923. It’s called Just Gone. It’s a scratchy old record, with a rather compressed acoustic, so it’s like putting your next to one end of a tunnel leading back a hundred years, but it’s a good example of the Creole Jazz Band’s style. Joe Oliver’s lead cornet clearly influenced Louis Armstrong’s later style. You have to listen hard to hear Satchmo in the background on this track, but it’s worth the effort. You’re listening to a piece of music history, and a wonderful piece at that.
Nine Modern Poets
Posted in Biographical, Education, Literature with tags Dylan Thomas, E.L. Black, John Betjeman, Nine Modern Poets, Philip Larkin, Poetry, R.S. Thomas, T.S. Eliot, Ted Hughes, W.B. Yeats, W.H. Auden, Wilfred Owen on April 5, 2023 by telescoperI recently acquired – at negligible expense – the above second-hand copy of the anthology Nine Modern Poets. I got a copy because this book was one we we studied when I was at school back in the 1970s. The First Edition was published way back in 1966, and it was reprinted until the mid-1980s but has long been superseded as a school poetry text by other anthologies. It has been out of print for many years so I had to find a second-hand copy via the internet. I bought some other second-hand anthologies too, which I may share in due course.
Anyway, the Nine Modern Poets are: W.B. Yeats, Wilfred Owen, T.S Eliot, John Betjeman, W.H. Auden, R.S. Thomas, Dylan Thomas, Philip Larkin, and Ted Hughes. Yes, they are all male.
Looking back it’s surprising to see John Betjeman in there, I’d have swapped him for Sylvia Plath (though her first collection, Colossus was only published in 1960 and the second, Ariel, in 1965 so these might have been too late), but the reason I look back on this book with some fondness, indeed nostalgia, is that it was this collection that introduced me to the poetry of R.S. Thomas, and I am very grateful to it for that.
The Last Endeavour
Posted in Crosswords, Television with tags Anton Lesser, D.S. MacNutt, Endeavour, Exeunt, Inspector Morse, Roger Allam, Shaun Evans, Ximenes on April 3, 2023 by telescoperAlthough it was broadcast on ITV in the UK on March 12th this year, the very last episode (Exeunt) of the detective series Endeavour wasn’t broadcast on Irish TV until last night, Sunday 2nd April. This series was the prequel to the series Inspector Morse the last episode of which aired in 2000; the first of that series was broadcast in 1987. Endeavour, in case you don’t know is Inspector Morse’s first name, something he usually kept quiet about. The sequel series, Lewis ended in 2015 (after 9 series), so on Sunday the entire Morse franchise, originally based on the novels by Colin Dexter, drew to a close. I imagined it would be like saying goodbye to an old friend.
When Endeavour first started (in 2012) I was very skeptical that it would work. It was asking a lot of Shaun Evans to play the younger Inspector Morse (who was marvelously played in the original series by John Thaw). In any case I thought it might turn out to be a cheap attempt to cash in on the Morse theme. I was however pleasantly surprised at how good the early episodes were, and became a regular viewer.
I won’t go through the entire back story created for Morse in Endeavour but the Pilot was set in 1965 and introduced the character of Detective Inspector Fred Thursday who was the young Endeavour’s mentor when he joined the Oxfordshire Police as a Detective Constable. One of the mysteries created by this new character is why Morse never mentioned him in any of the 33 episodes of Inspector Morse. This conundrum was resolved, partly at least, in the final episode.
So what did I make of the final episode? I’m sorry to say that it was a bit of a mess and I was disappointed. The script seemed to be trying to resolve as many loose ends left by the previous programmes as possible, and the way this was done was at times highly implausible. For example, Morse is rescued from being double-crossed by a corrupt policeman Arthur Lott at Blenheim Vale by a gang of bikers intent on revenge for a drugs-related killing who beat Lott to death. But would they really have left another policeman and potential witness (Morse) go free, especially as Morse also happened to have on him a big bagful of cash?
There were some nice touches though, especially in the tie-ups with later Morse. At one point reference is made to Morse’s possible transfer to Cowley under DCI Macnutt (the real name of the great crossword setter Ximenes, precursor to Azed; Colin Dexter was a huge crossword fan). We know that’s what Morse must have done because Macnutt appears in an episode of Inspector Morse called Masonic Mysteries. Macnutt has retired from the police force and joined the clergy, but Morse consults him about old cases as he has worked with him in the past.
There’s also a brief mention of a character we don’t meet called Robert Lewis…
But the scene in Exeunt that has caused most comment is very near the end. Inspector Thursday (who has to leave Oxford in a hurry) has given his old army service revolver to Morse. We see Morse sitting in a churchyard, alone. He takes a single round and places it in the cylinder of the revolver, spins it like he is about to play Russian Roulette, and snaps the gun shut. The camera cuts to a long short of the church. We hear a gunshot, and birds flutter into the air. It seems Morse has pulled the trigger. But we know he can’t die because there are 33 episodes to come! Sure enough we see him a few minutes later, alive and well, going to choir practice. So what’s going on?
For what it’s worth, I think the interpretation of this can be found in another scene that happens a bit earlier. Morse, fresh from the escapade at Blenheim Vale arrives late at the marriage of Joan Thursday (the Inspector’s daughter) to Detective Sergeant Jim Strange. We know Morse has had the hots for Joan for all nine series, but has never done anything about it. When he arrives at the wedding reception he tells Joan that he loves her, that he’s loved her for years, but now it’s too late as she is married. She replies that it’s not too late and they kiss passionately in front of all the wedding guests…
…but no. The scene rewinds and this time Morse greets Joan by calling her Mrs Thursday. There’s no kissing, just a hug. Morse remains a bachelor until his dying day.
What the script has done at this point at the wedding is to give us a glimpse of an alternative history that reveals what’s going on in Morse’s mind. I think it prepares us for what comes later with the churchyard and the revolver. That is the same idea. Morse is depressed that he’ll never have Joan, and that all his colleagues are moving away or retiring. He thinks of suicide and the gunshot represents that thought. It’s another alternative history. The whole story could have ended there. But in reality, he doesn’t kill himself. Perhaps he pulls the trigger, but the chamber is empty. Or perhaps he just changes his mind.
I wish the final episode had been better, and it has to be said that some others of the 33 episodes weren’t great either, but there were some cracking episodes too and Endeavour has overall been very good indeed, especially the acting of Shaun Evans and Roger Allam (Thursday) and Anton Lesser (DCS Bright), whose voice is heard at the end reading from The Tempest:
Our revels now are ended. These our actors,
As I foretold you, were all spirits and
Are melted into air, into thin air:
And, like the baseless fabric of this vision,
The cloud-capp'd towers, the gorgeous palaces,
The solemn temples, the great globe itself,
Yea, all which it inherit, shall dissolve
And, like this insubstantial pageant faded,
Leave not a rack behind. We are such stuff
As dreams are made on, and our little life
Is rounded with a sleep.
P.S. All 36 episodes of Endeavour were written by the same man, Russell Lewis.
Foirmlí agus Táblaí
Posted in Education, Maynooth with tags Foirmlí agus Táblaí, Log Tables, mathematics on April 1, 2023 by telescoperI’ve written on here before about Log Tables but since I’ve recently acquired a set of my own I thought I’d celebrate by mentioning them again. This is what the term “Log Tables” refers to in Ireland:
This book is in regular use in schools and colleges throughout Ireland, but that the term is a shorthand for a booklet containing a general collection of mathematical formulae, scientific data and other bits of stuff that might come in useful to students. There are a lot more formulae than tables, but everyone has calculators now so those aren’t really necessary. There is no table of logarithms in the Log Tables, actually. I suppose much older versions did have more tables, but as these were phased out the name just stuck and they’re still called Log Tables.
The official book costs €4. I bought it in Maynooth’s excellent local independent bookshop. The man who served me knew exactly what I meant when I asked for Log Tables.
I’m old enough to remember actually using tables of logarithms (and other mathematical tables of such things as square roots and trigonometric functions, in the form of lists of numbers) extensively at school. These were provided in this book of four-figure tables (which you can now buy for 1p on Amazon, plus p&p).
As a historical note I’ll point out that I was in the first year at my school that progressed to calculators rather than slide rules (in the third year) so I was never taught how to use the former. My set of four-figure tables which was so heavily used that it was falling to bits anyway, never got much use after that and I threw it out when I went to university despite the fact that I’m a notorious hoarder.
Students in Theoretical Physics at Maynooth are allowed to ask for Log Tables in any formal examination. The formulae contained therein are elementary in terms of physics, so won’t help very much with more advanced examinations, but I have no problem with students consulting the Log Tables if their mind goes a bit blank. It seems to me that an examination shouldn’t be a memory test, and giving students the basic formulae as a starting point if anything allows the examiner to concentrate on testing what matters much more, i.e. the ability to formulate and solve a problem. The greatest challenge of science education at University level is, in my opinion, convincing students that their brain is much more than a memory device.
Here’s an example page that shows some elementary formulae for Mechanics with explanations as Gaeilge in English.
These formulae come up in Physics and/or Applied Mathematics at Leaving Certificate but we don’t require students taking Mechanics in the first year to have done either of those subjects so many students find pages such as this very helpful.
I was interested to learn that colleagues in the Department of Mathematics and Statistics here in Maynooth do not allow the use of Log Tables in examinations. I don’t know why.
Test Piece
Posted in Biographical, Jazz with tags Petite Fleur on March 31, 2023 by telescoperThe newly enhanced version of this blog, improved at great expense, enables me to upload audio files. I thought I’d check out that facility by sharing this rendition of the tune Petite Fleur which was written in 1952 by the great Sidney Bechet but made famous by Monty Sunshine by a recording with Chris Barber’s band in 1959. The version here was performed in the 1990s in a little recording studio in Gateshead. Can you identify the clarinet player? (Hints: (i) it is not Sidney Bechet; (ii) nor is it Monty Sunshine; and (iii) it was my Dad playing the drums…)
Advanced Electromagnetism Theory Lecture Notes
Posted in Education, Maynooth, The Universe and Stuff with tags Advanced Electromagnetism, Maxwell Tensor, Maxwell's Equations on March 31, 2023 by telescoperAs a member of academic staff who teaches in a publicly funded University, and in the spirit of the Open Access movement, I think that as far as possible I should put the content of my lectures in the public domain. I’ve decided today to do this with my final-year module on Advanced Electromagnetism. Here you go.

Any questions?
If you think that isn’t much for the 17 lectures I’ve given so far, just look at what I started with:
I reckon I’ve made quite a lot of progress!
