Edgeworth Connections

Posted in History, The Universe and Stuff with tags , , , , , on October 25, 2024 by telescoper

It’s a small world.

This year I am supervising an undergraduate project student who is looking at approximations to probability distribution functions. This project was inspired by a nice paper on the arXiv by Elena Sellentin, Andrew Jaffe and Alan Heavens about the use of the Edgeworth series which I blogged about here.

It turns out that the student who picked this project hails from a place very close to Edgeworthstown in County Longford. I’ve been through there on the train going to and from Sligo, but I never thought much about the possible connection, assuming the name was a coincidence. When I met my project student yesterday for our weekly discussion, however, he told me he had looked into it and the results are very interesting.

The Edgeworth series was invented by Francis Ysidro Edgeworth (1845-1926) who was a political economist and philosopher was born in Edgeworthstown. He was the grandson of the Richard Lovell Edgeworth (1744-1817) who had no fewer than 22 children (including the novelist Maria Edgeworth) and was a founder member of the Royal Irish Academy. In a manner not untypical of the Anglo-Irish landed gentry, the Edgeworths renamed the local town from Meathas Troim (anglicized form Mostrim), c.f. Parsonstown.

There is a directly astronomical connection with the Edgeworth family too. Kenneth Edgeworth (1880-1972) was another member of the Edgeworth dynasty, `one of ‘the archetypal gentleman literary and scientific families’ who had sufficient private income to be able to pursue a diverse range of interests. Kenneth Edgeworth was an independent theoretical astronomer, best known for proposing the existence of a disc of bodies beyond the orbit of Neptune in the 1930s. Observations later confirmed the existence of this structure, often called the Kuiper belt or, especially in Irish circles, the Edgeworth-Kuiper belt.

Here’s the front page of one of his astronomical publications:

Anyway, what’s the probability that a student would randomly pick a project involving a method invented a person born just a few miles away from his family home?

O(G)HAM

Posted in History, Irish Language with tags , , on October 3, 2024 by telescoper

Here’s a fascinating video about a project looking into Ogham, an early-mediaeval way of writing that dates back to about the 4th Century AD.

As the video reflects, there’s some controversy about whether the ‘g’ is pronounced but most Irish people I know would say “Oham” rather than “Ogam”. Anyway, this video reports on a research collaboration between the University of Glasgow and Maynooth University that aims to harness Digital Technologies to Transform Understanding of Ogham Writing, from the 4th Century to the 21st.

Requiem for the Croppies – Seamus Heaney

The pockets of our greatcoats full of barley…
No kitchens on the run, no striking camp…
We moved quick and sudden in our own country.
The priest lay behind ditches with the tramp.
A people hardly marching… on the hike…
We found new tactics happening each day:
We’d cut through reins and rider with the pike
And stampede cattle into infantry,
Then retreat through hedges where cavalry must be thrown.
Until… on Vinegar Hill… the final conclave.
Terraced thousands died, shaking scythes at cannon.
The hillside blushed, soaked in our broken wave.
They buried us without shroud or coffin
And in August… the barley grew up out of our grave.

by Seamus Heaney (1939-2013)

This poem is about the Battle of Vinegar Hill which took place outside Enniscorthy in County Wexford on 21st June 1798. It was part of the Rebellion of the United Irishmen. The term “croppy” refers to the short cropped hair worn by the rebels, most of whom went into battle carrying only pikes against the artillery and muskets of the crown forces. The battle was a heavy defeat for the United Irishmen over a thousand of whom were killed in what Heaney calls the “final conclave” where the last hopes for the rebellion to succeed were finally crushed. The poem’s final line depicts the barley in the pockets of dead rebels growing through the soil used to bury them, suggesting that the dream of independence would live on.

Newgrange and JWST

Posted in History, The Universe and Stuff with tags , , on August 18, 2024 by telescoper

Although I won’t myself be able to attend, I’m happy to be able to use the medium of this blog to advertise the above public event which is taking place in the first week of September on the back of a week-long conference to celebrate the career of Professor Tom Ray of the Dublin Institute for Advanced Studies. That in turn follows hard on the heels of the Irish National Astronomy Meeting (INAM) which takes place in Galway on 29th and 30th August.

Anyway, the public event on 3rd September is free to attend but you need to register here, where it is described thusly:

The Newgrange Passage Tomb, a prehistoric monument in County Meath, Ireland, is one of the most remarkable examples of Neolithic art and architecture, dating back to around 3200 BC. This ancient structure, with its intricate stone carvings and precise alignment with the winter solstice sunrise, reflects the sophisticated astronomical knowledge of its builders.

With starkly different technology, the James Webb Space Telescope (JWST), launched in 2021, represents the pinnacle of modern astronomical achievement. JWST is designed to peer into the farthest reaches of the universe, capturing images and data from the formation of the earliest galaxies to the atmospheres of planets outside of/beyond our solar system.

Despite being separated by millennia, both Newgrange and JWST underscore humanity’s enduring quest to understand our place in the cosmos through the study of the stars and the universe.

As part of the celebration of the career of Professor Tom Ray the Dublin Institute for Advanced Studies and the Institute of Physics are delighted to host a public event on Newgrange and JWST. This is in recognition of Tom’s long interest in archaeoastronomy and Newgrange in particular, and his involvement with the JWST through the Mid-Infrared instrument (MIRI).

The talk will be delivered by Dr. Frank Prendergast, archaeoastronomer and Emeritus Research Fellow at Technological University Dublin, and Professor Gillian Wright, European Principal Investigator of MIRI and Director of the UK Astronomy Technology Centre in Edinburgh.

An Leabharlann

As I’ve mentioned before on this blog, over the past year or so I’ve been trying to catch up on my reading. My stack of books I’ve bought but never read is now down to half-a-dozen or so.

With sabbatical drawing to a close,  the next major life even appearing on the horizon is retirement. Since that will involve a considerable reduction in income, and consequently money to buy books, and my house already has quite a lot of books in it, I thought I’d join the local public library so that when I’ve cleared the backlog of bought books, I’ll read books from the library instead.

With that in mind, I just joined the public library on Main Street, Maynooth, which is only about  15 minutes’ walk from my house. It’s a small branch  library but is part of a larger network across County Kildare, with an extensive online catalogue from which one can acquire books on request. All this is free of charge.

Once I got my card, I had a quick look around the Maynooth branch. It has a good collection of classic literature (including poetry) as well as Irish and world history, which will keep me occupied for quite a while. The normal loan  period is 3 weeks, which provides an incentive to read the book reasonably quickly.

I borrowed books in large quantities from public libraries when I was a child. I’m actually looking forward to getting into the library habit again.

The Meaning of Everything by Simon Winchester

Posted in Biographical, History, Literature with tags , , , , , , , , , , on May 12, 2024 by telescoper

The most recent item on my (non-research-related) sabbatical reading list to be completed is The Meaning of Everything by Simon Winchester, subtitled “The Story of the Oxford English Dictionary”. I didn’t actually buy this book, but won it in a crossword competition back in February 2019. It didn’t arrive in Ireland until the end of May 2019, so it has taken me a bit less than 5 years to read it. I wish I’d read it earlier as it is fascinating and very well-written.

There’s quite a lot of information about the Oxford English Dictionary on the wikipedia page so I will keep it brief here. In short, the idea of a definitive dictionary of the English language emanated from the Philological Society and dates back to 1857, but real work didn’t start on it until a decade later. The whole project was many times on the brink of cancellation because the task of compiling the dictionary turned out to be much greater than was imagined at the outset. It was thought that the dictionary would be finished in a few years, but the First Edition was not completed until 1928. I think most people imagine that the OED has been around much longer than that!

Almost immediately work began on a supplement to include words that had entered usage during the decades needed to compile the original. A complete Second Edition was published in 1989.

The OED was actually first published in fascicles, softbound publications of about 300 pages that could be later sewn into a hard binding. These were quite expensive – 12/6 each. The first, A-Ant, was published in 1884. A complete list of these can be found here.

One might imagine that the laborious nature of the work involved in compiling a dictionary of this sort would make the story rather dull but it’s actually fascinating, both to see how the task was approached and to learn about some of the characters involved. As well as the Editors – who were paid a salary – the work relied heavily on hundreds of volunteer readers who would scour the literature looking for useful quotations that revealed the meaning of a word. By “the literature” I mean anything written – novels, non-fiction, newspapers, magazines, technical papers, anything. These volunteers would send in apposite quotations from which the compilers would construct definitions of the words. Some “headwords” have many meanings – set is an extreme example, with over 430 senses – and others – such as back – appear in a large number of compound words, all of which it had been decided needed to be illustrated with a quotation. The First Edition contained over 400,000 words and nearly two million quotations, all written and indexed laboriously by hand.

Among the volunteer readers were some extraordinary characters. One such was William Chester Minor, an American former surgeon who worked tirelessly for the Dictionary, sending his contributions in the post from an address in Crowthorne, Berkshire, which happened to be Broadmoor Psychiatric Hospital. The Chief Editor of the OED, James Murray, apparently assumed that W.C. Minor worked at Broadmoor but in fact he had been committed there in 1878 because, overcome by some form of psychosis, he had murdered a stranger and deemed insane. Minor carried on his work – using the prison guards as assistants – until he became seriously ill in 1902 after another psychotic episode during which he cut off his own penis.

The real star of the show however is English itself and this book offers some fascinating insights into the origin and evolution of the language. Almost nothing of the Celtic languages spoken throughout England before the Roman conquest survives into Old English (which used to be called Anglo-Saxon). This had a lexicon of around 50,000 words but only a few thousand of these survived in any form into Middle English and Modern English. Many common words in Old English were replaced and the language otherwise altered dramatically due to an influx of words, first from Scandinavia, via the Vikings, then from Norman French, and later on from diverse languages around the world. English has steadily absorbed and incorporated words from other languages for centuries, and is still doing so, though these words sometimes have a meaning in English that differs from their original.

In the light of this dramatic evolution in the language the Oxford English Dictionary was never intended to legislate on usage, but to register it; this is why its lexicographers relied so much on quotations in forming their definitions. This is also why the OED will never really be finished. The task of updating it nowadays is, on the one hand, made easier by the availability of computers and searchable databases but, on the other, made more difficult by the sheer amount of literature being produced.

I’ll send with one of the (apparently inadvertent) funny bits in the OED, from the second definition of the rarely used noun abbreviator:

An officer of the court of Rome, appointed… to draw up the Pope’s briefs…

I say it is inadvertent because the OED gives the earliest usage of the word briefs meaning underwear as 1930, after the publication of the First Edition (in which this appears).

A Table Alphabeticall

Posted in History, Literature with tags , , , on May 5, 2024 by telescoper

I’m having a lazy Sunday so instead of writing anything too demanding on here I thought I’d share something I stumbled across in a book I’ve been reading (and will probably review next week sometime). Not a lot of people know that the first true English dictionary was called A Table Alphabeticall which was created by Robert Cawdrey and first published in London in 1604, over 150 years before Samuel Johnson’s much more famous A Dictionary of the English Language.

This, on the left, is the frontispiece of the First Edition to A Table Alphabeticall:

Notice that it says it was compiled for the benefit and help of “Ladies, Gentlewomen, or any other unskilfull persons”. Ouch! By the Third Edition, published in 1613, this was amended to “all unskilfull persons”.

P.S. Notice the old-fashioned typesetting, especially the use of the “long s” which I have blogged about before.

Carrowmore, County Sligo

Posted in Architecture, History with tags , , , , , on May 1, 2024 by telescoper

Today is 1st May, so it’s the Labour Day Holiday in Barcelona. Colleagues in Ireland will have to wait until Monday 6th May for their equivalent holiday. The First of May, Beltane (Bealtaine in Irish), is a festival of pagan origin that roughly marks the mid-point between the Spring Equinox and the Summer Solstice. It’s one of the so-called Cross-Quarter Days that lie halfway between the equinoxes and solstices.

In view of the ancient origins of this holiday I thought I’d share some pictures of the amazing megalithic burial grounds at Carrowmore which is about 4km outside Sligo (where I have been on a secret mission). Carrowmore is the largest of the four megalithic cemeteries in Ireland in terms of the number of tombs, although the tombs are smaller in size and less complicated than the larger structures found at Brú na Bóinne. The structures at are also significantly older; there are signs of human habitation on the site going back at least 6000 years. The English name derives from the Irish An Cheathrú Mhór, which means ‘the great quarter’. Photographs don’t do justice to the extraordinary beauty of the landscape around the site but here is a panorama which gives some impression.

A visitor can easily understand why this was felt to be an appropriate last resting place for the Great and the Good. The surrounding topography is very interesting, as you can see from the first picture (of a model in the Visitor’s Centre); it’s on a peninsula between Sligo Harbour to the North and Ballysadare Bay to the South, and is surrounded on three sides by mountains. In particular, the site is overlooked from the west by Knocknarea, on top of which lies a large cairn, Miosgán Meadhbha, reputed to be the burial-place of the legendary Queen Maeve (Méabh in modern Irish). I was surprised to learn that this has never been excavated, so nobody really knows who or what is inside though it probably contains a passage tomb of similar form to those on the Carrowmore site. The cairn at the centre of Carrowmore, called Listoghil, the entrance to which you can see in one of the pictures, is a reconstruction.

Sadly, many other tombs were destroyed in the 19th Century, with stones being robbed to make walls when the land was enclosed, and large-scale quarrying for gravel in the area. Only some of the tombs are on publicly-owned land, but others are visible in nearby fields and indeed all around the area. There is even a stone circle in Sligo itself, on a housing estate called Abbeyquarter. Who knows what else is lurking under the unexcavated ground?

This forthcoming Bank Holiday weekend there is the Queen Maeve Festival in Sligo, but I will be in Barcelona.

Revolução dos Cravos

Posted in History, Music, Politics with tags , , , , , , on April 25, 2024 by telescoper

My office mate in Barcelona is Portuguese and he very proudly reminded me this morning that today, 25th April 2024, is the 50th anniversary of the Carnation Revolution that ultimately overthrew a fascist dictatorship and led Portugal towards becoming a progressive democracy. Just over a year later, General Franco died and Spain began its transition to democracy too. Both countries joined the European Community in 1986 and are now members of the European Union. It’s hard to believe, only 50 years on, that fascism is on the rise once more in Europe (and elsewhere). That makes it all the more important to remember the struggles of the not-so-distant past.

The signal for the Revolução dos Cravos in Portugal to begin was a song played on the radio. The result was remarkable. Although led by military officers dissatisfied with the ruling regime, it garnered a huge level of popular support and morphed into a coordinated campaign of mass civil resistance. When regime change was achieved, it was largely peaceful. The name “Carnation Revolution” refers to the flowers given to soldiers by people celebrating their liberation from authoritarianism.

Fascismo nunca mais! Vinte e cinco de abril sempre!

I couldn’t help sharing the song that triggered that huge historical moment. It is Grândola, Vila Morena by Zeca Afonso. Few people can lay claim to have written a song that brought down a dictatorship.

Diada de Sant Jordi

Posted in Barcelona, History with tags , , , , , , on April 23, 2024 by telescoper

Today, 23rd April, is Diada de Sant Jordi (Saint George’s Day) which, though not a public holiday, is a very special occasion in Barcelona. Saint George is of course familiar to me as the Patron Saint of England, and of quite a few other places, but wasn’t aware until a few weeks ago that he is also the Patron Saint of Catalonia.

Not much is known about Saint George, but it is believed that he was born in Cappadocia (modern-day Turkey, then part of the Roman Empire) to parents of Greek origin, and that he fought in the Roman army and died in 303 AD in Syria Palaestina (also part of the Roman Empire). There is no evidence that he ever visited England or Catalonia for that matter. It seems that he began to be venerated around about the time of the First Crusade, which happened over seven hundred years after his death.

Anyway, the Festa de Sant Jordi is celebrated in a very civilized and charming way in Barcelona. Traditionally the celebration involved giving gifts of flowers (especially roses) to women and gifts of books to men. That is obviously a bit sexist so nowadays you can give flowers and books to whomever you wish. In order to facilitate this, quite a large area of the Eixample district around my apartment is largely closed off to traffic today, refuse collections have been paused, and there are stalls selling books or flowers filling up the pavements. It was especially busy this morning on Passeig de Gràcia, where the combination of queues at the bookstalls and queues for the Casa Batlló generated a big crowd, but the atmosphere was very friendly and nice (apart from a few car drivers upset at the road closures).

Here are a couple of video clips which will hopefully give you an idea of what it was like:

And here are some random pics

I wish I could visit the celebrations again, but this afternoon I have to take the train to Madrid for a conference.
