Are You in The Weights?

Posted in Artificial Intelligence, Biographical with tags , , , , on June 22, 2026 by telescoper

Yesterday I found out about a site called intheweights.com , which reveals which people are “stored” in the weights of large language models. Those “weights” are billions of numerical values by which these AI models encode their knowledge. If you show up in them, the model considered you relevant enough during training to recall without tools such as web search.

The site queries several models to figure out who a specific person is, combines the results, and assigns a strength score.  According to the leaderboard, the current maximum strength score is 998, awarded too a person called Charlize Theron (of whom I have never heard); number Two is Rudyard Kipling, apparently. I’m surprised the top isn’t Taylor Swift. I guess these weights change with time too.

Being a vain person I typed in my name and found this:

The only reason I can think of that I score so highly is all that scraping of this blog site over the last year or so. The weights are obviously influenced by how much material there is available online by or about the person.

Anyway, give it a try. Are you In The Weights?

P.S. A number of other “Peter Coles” characters are also listed under my entry, some of them as far as I can see totally fictitious.

My Bucket’s Got a Hole in It

Posted in Biographical, Jazz, Maynooth with tags , , , , on June 14, 2026 by telescoper

“Only connect” is EM Forster’s best known adage about writing, though he didn’t mean it in the context of a “shitty WordPress blog”. Nevertheless I do find it fun sometimes to connect disparate things, so here goes.

I was doing a turn in the garden this afternoon when I noticed that an old bucket left here by the previous occupant had corroded enough to develop a hole:

This reminded me of the old song My Bucket’s Got a Hole in It and especially this very enjoyable version of it by Humphrey Lyttelton’s 1954 seven-piece live at the Conway Hall in London.

It’s hard to believe that it’s 18 years since Humph passed away, but it’s great to hear his voice again in the introduction to the track which ends the A side of the album Humph at the Conway. The cartoon on the cover is by him too. The record features Humph on trumpet, the clarinet by Wally Fawkes (who plays the first clarinet solo) and Bruce Turner on alto sax who switches to clarinet for the second solo but plays sax in the ensembles which sound absolutely terrific as a result. Many “trad” jazz fans took against Humph for including a saxophonist in his band, but Bruce Turner was a great musician and added a new dimension. The other members of the band were Johnny Parker (piano), Micky Ashman (bass), Freddy Legon (banjo) and George Hopkinson (drums).

So that’s one connection. Another is that yesterday saw the announcement of the King’s Birthday Honours in the UK, which was not covered widely here in in Ireland, but which independently reminded me that Humphrey Lyttelton turned down a knighthood on principle back in 1995. Good for him!

For Retired Engineers…

Many moons ago, just before I moved from Cardiff for my stint at Sussex University, I decided to ditch all the unsolicited letters and manuscripts I’ve accumulated over the years about “alternative” theories of relativity, cosmology, and whatnot. I don’t know why I had kept so many of them for so long, but I no longer have most of them. I did keep one or two of the best ones, however. Here’s an example:

I could never make head nor tail of this, but sometimes had a vague feeling that it might just be a sort of cosmic Rosetta Stone, offering up the Secrets of the Universe in diverse languages. Sadly, however, it’s more likely that the languages involved are Balderdash, Gibberish and Gobbledegook. At the time I wrote:

I regret to announce, therefore, that the plethora of papers telling me why Einstein was wrong, how the Universe is really in the shape of a spiral, how the Great Pyramid of Giza explains the Higgs Boson, and why the Big Bang couldn’t have happened, will have to go to the Great Shredder in the Sky (if that’s where it is).

Anyway, to all my correspondents all I can say is that I’ve enjoyed reading your letters – you must be very fond of your old typewriters – and I’m grateful for the time you took to draw the diagrams by hand in so many lovely colours. And I’m impressed by your qualifications as Electrical Engineers. Really. I’m sorry I didn’t reply to you all individually, but I just didn’t have the time. And now it pains me to realise I don’t have the space either…

I still get such things, of course, but they always come by email nowadays and usually end up in the spam folder, where I do not disturb them. I never reply, of course. Life’s too short.

I know I’m not the only one to have noticed the fact that many – indeed most – such correspondents are Electrical Engineers (usually retired). I was delighted therefore to see that there’s now a nice little paper on arXiv by David Garfinkle with the title Relativity for Retired Engineers and the abstract:

We provide some guidance and examples to clear up common misconceptions about special relativity. These misconceptions often come from trying to express the truths of special relativity in Newtonian terms rather than in terms more natural to special relativity itself. This conceptual stance can also help in attaining a better understanding of general relativity.

Readers may consider referring their correspondents to this source…

What’s the French for Schadenfreude?

Posted in Astrohype, Biographical with tags , , , on June 12, 2026 by telescoper

Once upon a time – in the summer of 2022 – I posted a silly little joke on Twitter (before I left there, obviously):

I thought a few people might find it funny, but it took off beyond my expectations. By my standards over 5000 “likes” counts as “going viral” (as you young people say). Most people saw the joke immediately – if you don’t get it, the image is of a slice of choriz,o not an astronomical object – and some even joined in with puns and other jokes. Even funnier, some respondents earnestly shared their devastating insight that it was chorizo (or some variant thereof). I honestly didn’t think anyone would think that I was seriously trying to pass it off as a JWST picture; it was just meant to be silly. But there you go. That’s Twitter. I should also report that some people looked at the rainbow flags in my profile and proceeded to indulge in some homophobic abuse. That’s Twitter too.

Anyway, the day after I posted the image it seems a prominent French physicist called Etienne Klein who has many times more Twitter followers than I ever did, posted an embellished version of the same joke.

To cut a long story short that led to ChorizoGate, a story which made it into numerous newspapers, from the Daily Star to The Times, and even got coverage on CNN News and the RTÉ website. More exciting and even Physics World! In nearly all the stories I’ve seen, the image, together with the JWST connection, is attributed to Étienne Klein who is apparently very well known in France as a popularizer of science in the French language. Because he writes and broadcasts in French he is not so well known outside France.

In a post on this affair at the time, I said

To be honest I’m quite relieved to have avoided the media notoriety surrounding ChorizoGate, especially as it means I’ve avoided being on the front page of the Daily Star! Dr Klein is welcome to the publicity, though perhaps it might backfire on him…

And backfire it has.

Étienne Klein’s appropriation of a silly joke was of no consequence, but at the time I couldn’t help wondering how someone who would do that might behave with things that actually matter. Now I know the answer, and it’s more than worrying. An investigation into the PhD thesis of Etienne Klein by Paris Cité University has concluded that there is extensive evidence of plagiarism in it. Who needs AI when you have Etienne Klein? The University has now decided to rescind Klein’s doctorate, which was awarded in 1999.

What’s the French for Schadenfreude?

Leaving Again

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

It is an important day for many young people in Ireland because the Junior Certificate and Leaving Certificate examinations both start today, so the first thing I need to do is wish everyone starting their examinations the very best of luck!

Among other things, the results of the leaving certificate examinations are important for September’s university admissions. In the system operating in England and Wales the standard qualification for entry is the GCE A-level. Most students take A-levels in three subjects, which gives them a relatively narrow focus although the range of subjects to choose from is rather large. In Ireland the standard qualification is the Leaving Certificate, which comprises a minimum of six subjects, with many students taking more than this. This gives students a broader range of knowledge at the sacrifice (perhaps) of a certain amount of depth; it has been decreed for entry into this system that an Irish Leaving Certificate subject counts as about 2/3 of an A-level subject for admissions purposes, so Irish students do the equivalent of at least four A-levels, and many do more than this. It’s also worth noting that all students have to take Mathematics at Leaving Certificate level. One can choose to do Leaving Certificate subjects at Ordinary or Higher level and there’s quite a big difference between the two, especially in Mathematics.

Overall I prefer the Leaving Certificate over the UK system of A-levels, partly the former gives the students a broader range of subjects than the latter. I would have liked to have been allowed to take at least one arts subject past O-level, for example. Another reason is that all students across the country take the same examination, so the difficulty or otherwise of the papers is a topic of national conversation. There will no doubt be many reactions in the media over the forthcoming days!

Anyway, tomorrow is a significant date for me (in more ways than one) so I’m up early this morning before heading off on a short journey to mark the occasion in style.

Lá Saoire i mí Mheitheamh

Posted in Biographical, Irish Language, LGBTQ+ on June 1, 2026 by telescoper

Today, 1st June, has been (and indeed continues to be for a few hours) the June Bank Holiday (Lá Saoire i mí Mheitheamh) in Ireland. It is the equivalent of the usual May Bank Holiday in the UK in that both have their origin in the old festival of Whitsuntide (or Pentecost) which falls on the 7th Sunday after Easter. Because the date of Easter moves around in the calendar so does Whit Sunday, but it is usually in late May or early June. Pentecost was actually on Sunday 24th May this year. Here in Ireland the Bank Holiday is always on the first Monday in June whereas on the other side of the Irish Sea it is on the last Monday in May. This year the weather was better last Monday, but you can’t have everything.

Although I’m only at beginners’ level in Irish, the phrase Lá Saoire i mí Mheitheamh gives me another chance to bore you about it. It’s actually quite a straightforward phrase until you reach the last word. “Lá” means “day” and “Saoire” means “leave” or “vacation” so “Lá Saoire” means “holiday”; “i” is a prepositional pronoun meaning “in” and “mí” means “month”. So far so good.

The word for June, however, is Meitheamh (at least when it is in the nominative singular case). Irish is an inflected language, which means that words change form according to their grammatical function. As an Indo-European language, Irish is distantly related to Latin which has six grammatical cases for nouns (actually seven if you count the rarely used locative case). Irish has only four cases – there’s no ablative and, curiously, no distinction between nominative and accusative. That leaves nominative, dative, genitive, and vocative. The dative – used after simple prepositions – is only rarely distinct from the nominative so basically the ones you have to learn are the genitive and the vocative.

In Latin cases are indicated by changes to the end of a word, but in Irish they involve initial mutations. In the example of “mí Mheitheamh” meaning “month of June”, requiring the genitive form of “June”, the initial consonant “M” undergoes lenition (softening) to sound more like a “v”. In old Irish texts this would be indicated by a dot over the M but in modern orthography it is indicated by writing an “h” after the consonant. This is called a séimhiú (pronounced “shay-voo” ). Note the softened m in the middle of that word too but it’s not a mutation – it’s just part of the regular spelling of the word, as is the -mh at the end of Meitheamh. There’s also a softened “t” in the middle of Meitheamh which makes it vrtually disappear in pronunciation. Meitheamh is thus pronounced something like “Meh-hiv” whereas “Mheitheamh” is something like “Veh-hiv”.

As well as being Lá Saoire i mí Mheitheamh, today is also the start of Pride Month, so let me take the opportunity to say Bród sona daoibh a chairde!

A Room with a View

The spell of warm sunny weather has made a huge difference to the view from my office window:

Well, what did you expect to see from a Maynooth University office window? Sydney Opera House perhaps? The Hanging Gardens of Babylon? Herds of Wildebeest sweeping majestically across …

On Blow-Ins

Posted in Biographical, Maynooth with tags , , on May 25, 2026 by telescoper
ox-eye daisies

At the start of the spring gardening season I decided to leave a bed that I had cleared unplanted to see what would grow there of its own accord. I expected standard weeds like dandelions, and did get a few of those, but more recently I have a considerable number of Ox-eye Daisies (Leucanthemum vulgare). The flowers look very like those of regular daisies (of which I also have a few on the front lawn) but the plants are much bigger: I estimate they’re about 80cm tall. Anyway, I find the white and yellow very striking against the green foliage behind so I’m very happy to see these wild flowers thriving.

These must have blown in as seeds, along with the numerous other wild flowers I have in the garden. That reminds me that the term “blow-in” is used colloquially in Ireland to denote someone who has just moved into a town or village where they have no deep familial roots. I’ve been called a “blow-in” many times, not always in a friendly way.

This reminds me of  an article I saw in the Irish Times soon after arriving here about British immigrants in Ireland. Being one such myself I find a lot of it rings true. You can read the article here (I don’t think it’s behind a paywall). I think it’s well worth a look.

I found quite a few things in it resonate quite strongly with my experiences since I arrived here eight and a half years ago. Top of these was the realization of just how ignorant I was about Irish history, thanks to the almost total neglect of this topic in British schools. Lack of education inevitably leads to lack of understanding and more often than not leads to prejudice and one finds a lot of that in the attitude of British people, even senior figures (many of them “educated” at Oxford) who are supposed to know better.

I was also struck by the “Not Really Irish” tag, which I think about rather a lot. It’s not really just a question of whether or not you have Irish citizenship or an Irish passport, it’s about the extent to which you belong. I spent over fifty years living in England and Wales so I’m missing a huge amount of cultural background pertaining to Ireland. I won’t ever be able to catch up all that so I don’t suppose I’ll ever feel `really Irish’. Of course people speak English here, but I’m very conscious that I have a funny accent. I suppose that means I’ll always feel like a stranger in Ireland. If there is predominant attitude towards the British over here, however, in my experience it is one of sympathy rather than hostility.

Anyway, since I am a metaphorical blow-in I suppose it’s only fair that I have so many literal ones in my garden!

Not in Barcelona…

Posted in Barcelona, Biographical, Maynooth with tags , , , on May 25, 2026 by telescoper

So much has happened since that it’s hard to believe that just two years ago I was enjoying a sabbatical in Barcelona. I was delighted when it was announced that this year’s Euclid Consortium Meeting would be held there, but when I saw the dates (25th to 29th May) I was worried that the meeting might clash with examining duties. When the examination timetable was published a couple of months ago, that possibility became a reality and I realized that I couldn’t attend. In fact I have an examination to deal with tomorrow, and will be grading the scripts for the rest of the week ahead of the Bank Holiday weekend.

It’s a shame I can’t make the EC meeting because this will be the last one before the first main release of data, DR1, which is scheduled to take place on October 21st this year. I’ve been following progress in the science working group on galaxy clustering via weekly Zoom conferences, but it would have been nice to see what has been going on in the other groups as well as catching up with colleagues in person as opposed to online.

The second data release, DR2 will not happen until March 2029, by which time I will have retired. In fact there will be at most two Euclid Consortium meetings that I can attend – in 2027 and 2028 – and the second of those may be after my retirement. The final data release, DR3, will happen in October 2031.

It’s worth also mentioning that there will be another Quick Release of data, this one from the Euclid Galactic Bulge Survey, on June 24 this year. There will be quite a lot of press activity around that, but I’m not involved in it.

Here is the complete timeline for reference:

I’d like to take this opportunity to wish everyone involved in the Euclid Consortium Meeting an enjoyable and productive time in Barcelona as well as a fun stay in what is truly an amazing city. I’ll be enjoying the beautiful weather in Maynooth (25°C and sunny) while all the participants are slaving over hot cosmology.

On My Knees

Posted in Biographical, Education, Maynooth with tags , , , , on May 22, 2026 by telescoper

It has taken a bit longer that I expected to get this far but I have now completed the grading of one of my modules. It wasn’t the written examination that took all the time, but the marking of the computational physics projects. This is always a slow job but for some reason it took even longer this year. Anyway, all components of the assessment for that module are now done and dusted and everything uploaded.

To add to the fun and games, last week I did the biannual trip to Naas for my anti-arthritis injections. I’ve been doing this regularly for some years now and it has become routine. When I first started I was told that there was a risk of one or both knees swelling up, but that has never happened. Until last week, that is. My right knee decided to swell up alarmingly. Although this was not really painful, I was forced to stay at home to rest and periodically apply a bag of ice. That worked well enough that I could go to last Friday’s concert (with the aid of a walking-stick) but it wasn’t until Sunday that I was properly recovered.

The alarm having passed I am now starting to feel the benefit of the jabs. I am planning sometime soon to walk from Maynooth to Dublin along the Royal Canal, that being the last leg of the National Famine Way. I want to be sure I can manage the 27km walk before attempting to do the full walk later in the summer. The weather is set fair for a few days so I might give it a go next week, assuming I manage to finish all my examining duties promptly. It’s the season finale at the National Concert Hall next Friday – followed by a long weekend break when I will be travelling a little, so I might try to do it on Thursday.

My next examination is not until Tuesday morning so, after several days of being shut away doing corrections, I can now spend a few days until the scripts are ready to collect doing numerous things that I’ve let slip while I’ve been busy. For one thing I have an inbox full of unanswered emails to attend to.

But for now I’m quite tired and in the mood only to vegetate.
