There Will Come Soft Rains

Posted in Literature, Poetry with tags , , , on August 4, 2026 by telescoper

In 1950 Ray Bradbury wrote a short story called There Will Come Soft Rains. The story appears in a collection called The Martian Chronicles. The title comes from poem of the same title, written in 1918 as a response to the horrors of World War 1:

There will come soft rains and the smell of the ground,
And swallows circling with their shimmering sound;
And frogs in the pools, singing at night,
And wild plum trees in tremulous white,
Robins will wear their feathery fire,
Whistling their whims on a low fence-wire;
And not one will know of the war, not one
Will care at last when it is done.
Not one would mind, neither bird nor tree,
If mankind perished utterly;
And Spring herself, when she woke at dawn,
Would scarcely know that we were gone.

by Sara Teasdale (1884-1933)

The Ray Bradbury story is set in the (then) distant future and describes, in a typically eery and unsettling way, the aftermath of a nuclear holocaust. One house, in Allendale Carlifornia, fully automated to provide for the comfort of its owners, carries on functioning after the owners are both vapourised by a nuclear blast. Beds continue to be made, meals prepared, floors cleaned, and dishes washed, by systems oblivious to the fact the owners are no more. The house recites to the ladyof the house one of her favoruite poems, There Will Come Soft Rains by Sara Teasdale. Then a fire starts by accident and the house burns to the ground.

I was reminded today that the date of the story (in the original version) is August 4, 2026. I looked for my copy of The Martian Chronicles when I got home but couldn’t find it. Here, however, are the opening few paragraphs:

The full text of the story can be found here (among a number of other places). It’s out of copyright.

Lá Saoire i mí Lúnasa

Posted in Biographical, Education, mathematics, Maynooth with tags , , , , on August 3, 2026 by telescoper

Today, Monday 3rd August 2026, being the first Monday in August, is a Bank Holiday in Ireland. This holiday was created by the Bank Holiday Act of 1871 when Ireland was under British rule. While the August Bank Holiday was subsequently moved to the end of August in England and Wales, it has remained at the start of August in Ireland. It has been a nice morning weather-wise, but in true Bank Holiday fashion we’re promised heavy rain later on, with a chance of thunderstorms.

As I mentioned on Saturday, the first day of August marks the old pagan festival of Lughnasadh, named after the God Lugh, on which is celebrated the beginning of the harvest season. This coincides with the English Lammas Day, one of many Christian festivals with pagan origins. Traditionally this is the start of the harvest season and is celebrated accordingly, with rites involving the first fruit and bread baked from flour obtained from the first corn. It is also one of the cross-quarter days, lying roughly half-way between the Summer Solstice and the Autumnal Equinox (in the Northern Hemisphere).

Two years ago at this time I was still on sabbatical. That seems like ages ago! When I resumed teaching, in September 2024, I had to teach two modules I’d never taught before: a fourth-year Mathematical physics course on Differential Equations and Complex Analysis and a second-year Engineering Mathematics course. I am doing both of these again so resumption of teaching in September won’t be as challenging, although I will be changing a few things in the light of last year’s experience. Lectures start on Monday 22nd September.

After I return to work tomorrow the next big item on the agenda is the repeat examination period, which starts on Wednesday August 5th. The first paper for which I have responsibility is on Friday 7th, but I won’t be able to get the scripts until Monday 10th so I have a bit of time to do other stuff before I start marking. I am not expecting many scripts, actually, so it shouldn’t be too onerous a task to get them done promptly.

Next week also sees the deadline for the dissertations for our MSc course. I have been supervising a student this year and will probably be asked to give comments on the final draft of his report. Then the MSc students have their presentations on Friday 14th August. They have all completed the taught component of the course so the only thing left to assess are these projects. Students will get their final results later this month, along with the resitting undergraduate students.

In between all this we have our Eclipse Event on August 12th. This sold out very quickly so we expect a good turnout. The event was advertised quite a bit in the local media, e.g. here and here:

The viewing of the eclipse will of course depend on the weather, but we have talks lined up indoors and a pop-up planetarium so I hope people will turn up even if the weather isn’t great. Although it is officially full, there may be a few returns, so it is worth checking on the day to see if we can fit you in.

Anyway, after the repeat examinations and project assessments are done, the marks uploaded, and the Undergraduate and Postgraduate Examination Boards have done their work, the next job will be to prepare for the new intake of students. This year’s Leaving Certificate results will be announced on Friday 21st August, at which point we’ll see how many students (if any) we have studying Physics next academic year (which, if all goes to plan, will be my penultimate…)

News from arXiv…

Posted in Open Access with tags , , , , , , on August 2, 2026 by telescoper

I saw recently an announcement that arXiv – which recently became a standalone nonprofit organization – now hosts more than three million articles. That message took me to a post on the arXiv blog from which I learnt that said blog is on WordPress which makes it possible to include embedded links from this WordPress blog, i.e.:

arXiv now hosts over 3 million articles

This in turn reminded me to answer a question that people sometimes ask about the Open Journal of Astrophysics, namely what would happen if arXiv went offline? Since OJAp is an arXiv-overlay journal this would appear to be fatal. We have been keeping duplicates of all the papers we publish, and associated metadata, in a local repository so that if arXiv went down we could reistate them fairly quickly. All we would need to do is alter the overlay to point to a different web address: there is no reason at all why the overlay idea can’t be adapted to other forms of repository.

Recently, however, arXiv decided to do a similar thing for all its articles. Here is a blog post about it:

arXiv future proofs access to research with third-party digital preservation

I blogged about the first stage of this here.

Anyway, if you use arXiv at all – which will include most astrophysicists – then it would be a good idea to follow the arXiv blog as there is very important news on it, including information about alterations to the schedule of announcements.

Lughnasadh – The Start of Autumn

Posted in Biographical, Education, Maynooth with tags , , , , , on August 1, 2026 by telescoper

Today is 1st August, which is marked by the old Celtic festival of Lughnasadh, named after the God Lugh. This coincides with the English Lammas Day, one of many Christian festivals with pagan origins. The word for August in modern Irish is Lúnasa, a name derived from the old Celtic word.

Traditionally 1st August marks the start of the harvest season and is celebrated accordingly, with rites involving the first fruit and bread baked from flour obtained from the first corn. It is also one of the cross-quarter days, lying roughly half-way between the Summer Solstice and the Autumnal Equinox (in the Northern Hemisphere).

In the Northern hemisphere, from an astronomical point of view, the solar year is defined by the two solstices (summer, around June 21st and winter, around December 21st) and the equinoxes (Spring, around March 21st, and Autumn, around September 21st). These four events divide the year into four roughly equal parts of about 13 weeks each. If you divide each of these intervals in two you divide the year into eight pieces of six and a bit weeks each. The dates midway between the astronomical events mentioned above are (roughly) :

  • 1st February: Imbolc (Candlemas)
  • 1st May: Beltane (Mayday)
  • 1st August: Lughnasadh (Lammas)
  • 1st November: Samhain (All Saints Day)

The names I’ve added are taken from the Celtic/neo-Pagan (and Christian terms) for these cross-quarter days. These timings are rough because the dates of the equinoxes and solstices vary from year to year. Imbolc is often taken to be the 2nd of February (Groundhog Day) and Samhain is sometimes taken to be October 31st, Halloween. But hopefully you get the point. All four of thes days have a Bank Holiday associated with them (on the first Monday after the respective date); this Monday (3rd August) is a Bank Holiday in Ireland.

Some folk in Ireland regard August 1st as the first day of Autumn, just as 1st February is regarded as the first day of Spring and 1st May is the start of Summer. Indeed, our annual cycle of repeat examinations at Maynooth always happens in early to mid-August and these examinations are officially called the Autumn repeats. I rest my case. In my time here I have also noticed that May, June and July do tend to have significantly better weather than August, although I’m pleased to say that the weather isn’t particularly autumnal today.

Weekly Update from the Open Journal of Astrophysics 01/08/2026

Posted in OJAp Papers, Open Access, The Universe and Stuff with tags , , , , , , , , , , , , , , , , , , , , on August 1, 2026 by telescoper

It’s time once more for another Saturday update of activity at the Open Journal of Astrophysics. Since the last update we have published a further three papers, bringing the number in Volume 9 (2026) to 163 and the total so far published by OJAp up to 611.

I continue to include the posts made on our Mastodon account (on Fediscience); these announcements also show the DOI for each paper.

The first paper to report this week was published on Tuesday 28th July in the folder Cosmology and Nongalactic Astrophysics. “The Origins of the Bulk Flow” by Richard Watkins & Trajan Clark (Willamett U., USA) and Hume A Feldman (U. Kansas, USA) analyzes the origin of large-scale bulk flow using the CosmicFlows-4 catalog, finding that it is largely influenced by structures beyond 200 h-1 Mpc, challenging previous assumptions.

The Fallen, by Louise Brangan

Posted in History, Literature with tags , , on July 31, 2026 by telescoper

I’ve just finished reading The Fallen: The Magdalene Laundries & Ireland’s Legacy of Shame by Louise Brangan, which I bought a couple of months ago. This tells the shocking story of Ireland’s Magdalene Laundries, institutions run by a variety of religious orders designed to accommodate “fallen” women and girls. Also known as “Penitents”, the inmates of these institutions were a mixture of the poor and unwanted, orphans, disabled, those who had suffered familial abuse, and those who simply didn’t conform to Ireland’s self-image of a virtuous Roman Catholic state.

After Independence in 1922 these institutions, which had already been in existence for over a century, became a sort of dumping ground for inconvenient woman of all kinds. Once inside, the Penitents – most of whom hadn’t really done anything wrong – were stripped of what meagre possessions they had, had their hair shorn, their names were erased, and they were put to hard menial labour washing and drying clothes. They were fed and housed – after a fashion – but conditions were damp and unsanitary and they were forbidden to make friendships with their companions, or even talk to them. They were locked inside and forbidden to leave unless and until the nuns decided they could, which was often never. The Magdalene Laundries were prisons in which every inmate was serving an indefinite sentence of hard labour.

Not surprisingly, the result of this soul-destroying regime was that many of the Penitents became completely institutionalised, some living our their days in a man-made purgatory. Perhaps the most shocking thing of all is the last of these terrible places – which was on what is now Sean McDermott Street in North Dublin – didn’t close until 1996. This book was published to mark the 30th anniversary of this event.

The book is a scholarly work, woven around the oral testimonies of several women, measured in tone but with an unmistakeable undertone of righteous indignitation. It also sets the story of the Magdalene Laundries in the context of 20th Century Irish history, especially the rise of the Catholic theocracy under de Valera and it subsequent fall in the wake of major scandals, of which the Magdalene Laundries were one. As a relative newcomer to Ireland, I was unaware of the true nature of these places and found this book educational as well as deeply moving.

Some comments cut very much to the bone. Here is a paragraph concerning a woman known in the book as Carmel who had been taken to Sunday’s Well for reasons she was never told to find that many of the other women there were quite elderly and infirm:

Going to bed that first night, Carmel had thought that she had been sent to Sunday’s Well to care for the old women. Gradually, she had come to realise, like many others before her, that she had been sent to the Laundry not to look after these women but to become one of them.

Another passage that hit me hard was about the disinterment, in 1993, of 133 bodies from a mass grave when the Sisters of Our Lady of Charity decided to sell the land to a property developer. The graves of the women, who had died while incarcerated at a Magdalene Laundry, were unmarked; another 22 were found later. Shamefully, only 75 death certificates had ever been registered. It is against the law in Ireland to bury someone without registering their death so 80 crimes had been committed over the years. No action was ever taken.

In recent years there has been a redress scheme for the survivors of these institutions, but what financial compensation can possibly be adequate for a lifetime of penal servitude? The most important message of this book is that stories like this have to be told. Ireland must confront the dark side of its recent past. Silence can be the worst form of dishonesty.

Astronomy Envy

Posted in Biographical, Education, Science Politics with tags , , , on July 30, 2026 by telescoper

In 1998 the Department of Physics at the University of Nottingham was struggling in both research and undergraduate recruitment. To remedy the situation it decided to add a new group in Astronomy. The main idea was that having astronomy in its portfolio would attract more students and boost its standing in the Research Assessment Exercise (as it was then called). I was one of the people appointed to turn that decision into reality, and I’m glad to say the result was a success. Undergraduate numbers increased and in the next RAE Nottingham Physics scored a ‘5’, compared to the previous ‘4’. The Astronomy group quickly gained recognition across the UK and abroad, and another group was added, in Astroparticle Physics.

When the new Astronomy group was set up in 1999, the Department of Physics changed its name to the School of Physics & Astronomy. Despite the positive effect of this new activity, it was immediately clear that some members of staff resented it. A new letterhead was created, referring to the School of Physics & Astronomy, and one (very distinguished) senior member of the former Department always crossed off the “and Astronomy” whenever he used it. Others were surprised that the astronomers wanted to do research, when they felt that astronomy was just a bit of window-dressing for undergraduate recruitment. The astronomers were just there to do teaching, so that the “proper physicists” – mostly in semiconductor physics, nanoscience and other areas of condensed matter physics – could spend more time in their laboratories. I’m not saying that every physicist thought this – most were genuinely appreciative and supportive – but there were more than a few grumblers.

The undertone of all this is the envy that some physicists feel towards astronomy. Astronomers get invited to talk about their work to the general public and to amateur astronomy clubs, while there are no such calls for semiconductor physicists. Nobel prizes go to cosmology and astrophysics much more frequently than some would like. Above all there is the view that astronomy is all very well for bringing students in, but once at university the students must be converted to “proper physics”. Astronomers (including astrophysicists and cosmologists) should not get “notions” (as the Irish say). The short-sighted view that scientific research in universities should be aimed at short-term commercial gain amplifies this attitude, but does not entirely account for it.

These thoughts have been at the back of my mind for some time, but they came to the front again with the recent news about cuts to STFC funding. The callous attitude shown to the UK astronomy research community, implying that it should be grateful that it is not being cut by more than the disastrous level announced, indicates (to me) that there’s much more to what is going on than a mere budgetary issue. There is a deliberate plan to slap down a community that has grown too big for its boots.

The consequences for UK astronomy, and UK physics in general, are dire. Astronomy has kept many physics departments afloat for the last several decades. Without it, physics will fail in all but a handful of universities. That’s where envy takes you.

Jodrell Bank – Patric Dickinson

Posted in Poetry with tags , , , , on July 29, 2026 by telescoper 
Who were they, what lonely men
Imposed upon the fact of night
The fiction of constellations
And made commensurable
The distances between
Themselves their loves and their doubt
Of government and nations;
Who made the dark stable

When the light was not? Now
We receive the blind codes
Of spaces beyond the span
Of our myths, and a long dead star
May only echo how
There are no loves nor gods
Men can invent to explain
How lonely all men are.

This poem is from a collection called “The World I See”, by Patric Dickinson, which was published in 1960. The poem was inspired by a visit to Jodrell Bank observatory. I have posted it before, but it seems apt to post it again now.

The STFC Cuts

Posted in Artificial Intelligence, Science Politics, The Universe and Stuff with tags , , , , , , , , on July 28, 2026 by telescoper

News came out yesterday of the results of the latest funding prioritization exercise by the UK Science and Technology Facilities Council (STFC). The total savings being made by cuts to astronomy and particle physics are less than the funds allocated to just one AI lab! It seems STFC has to bear the brunt of savings needed so that UKRI, the organization under which STFC sits, can gamble much more on Artificial Intelligence and Quantum Technology. It seems to me that these are two bubbles ready to burst and the decision to sink money into them is not only unwise, it places the UK science base at serious risk of collapse.

Anyway, you can find the list of specific cuts here. Radio astronomy is hit particularly hard. The interferometric network e-Merlin is not prioritized and its funding will run out in 2028. That puts Jodrell Bank Observatory in danger of complete closure unless an alternative source of funding can be found. The last time STFC had a financial crisis was in 2009 and e-Merlin might well have been cut then but survived thanks to political intervention at the highest level. I suppose that could happen again, but I wouldn’t bet on it. More bad news is that the UK Square Kilometre Array Regional Centre, with SKA itself already financially troubled, is also earmarked for cuts.

The 76m Lovell Telescope at Jodrell Bank, now under threat of closure

And that’s just radio astronomy and Jodrell Bank is one of the highest-profile casualties. There are cuts and cancellations in many other areas too; see here for a full list.

The Astronomer Royal for Scotland, Catherine Heymans, has used her platform to campaign against these damaging and short-sighted cuts to UK astronomy, including on social media:

Just off #BBCR4 World at One, arguing the importance of discovery science (like Jodrell) for long-term economic growth. I said I was heartbroken at the news: evidence just look at how exceptionally excited me & @mamaphysikerin.bsky.social were when we got to stand inside Lovell back in 2017 🥰 🔭🧪

— Astronomer Royal for Scotland | Catherine Heymans (@astroroyalscot.bsky.social) 2026-07-27T12:38:30.873Z

The same can’t be said for the Astronomer Royal herself, Prof. Michele Dougherty. The reason for that is Prof. Dougherty is also Executive Chair of STFC and is therefore responsible for implementing the cuts. How it is possible for her to remain in both posts is nothing short of a scandal. Such a glaring conflict of interest cannot be allowed to stand. Indeed, Prof. Dougherty was elected to serve as President of the Institute of Physics from October 2025 but stepped down in January 2026 citing concerns of a conflict of interest with her role at STFC. It’s a slap in the face to the Astronomy community that it is not deemed worthy of such consideration.

The Mayo Curse is Lifted

Posted in GAA, Irish Language, Maynooth with tags , , , , on July 27, 2026 by telescoper

I follow the hurling more than the Gaelic football, but I did watch yesterday’s memorable All-Ireland final between Kerry and Mayo which attracted a TV audience of over a million people. Bear in mind that the population of the Republic of Ireland is just 5 million.

Kerry were strong favourites ahead of the game, but it was underdogs Mayo (who played in all-white kit) that prevailed, deservedly, by 1-20 to 1-17.

This result is huge news because it is 75 years since Mayo won the All-Ireland title – they had been beaten finalists six times since 2012, including 2020 and 2021. The last time they won was in 1951. The Mayo colours were much in evidence in Maynooth last night as people celebrated their team lifting the Sam Maguire Cup along with the lifting of the Mayo Curse. I don’t think any members of the Mayo team will be buying their own drinks for a long time!

I like this very wholesome picture showing Mayo’s Jordan Flynn and Kobe McDonald on the pitch at Croke Park after the end of the game. That moment will stay with them for the rest of their lives.

Incidentally the Irish name for Mayo, Maigh Eo, means “Plain of the Yew Trees” and the Maigh is also responsible for the first bit of “Maynooth”.
