Everybody Digs Bill Evans

Posted in Film, Jazz with tags , , , , , , on September 20, 2026 by telescoper

I’m not exactly an avid cinema-goer but I couldn’t resist taking a short trip into Dublin to see Everybody Digs Bill Evans, a biographical drama about the late great jazz pianist Bill Evans, the trailer for which is above.

I suppose Bill Evans is best known for his wonderful contributions to what many people regard as the greatest jazz album of all time, Kind of Blue which was released in 1959. This film, however, focuses on the period after he had left the Miles Davis band that made that album in order to pursue a career leading a piano trio. It could be argued that it was this step that led to Bill Evans’s most important contribution to the evolution of jazz because he basically created the modern piano trio, converting it from what it had been before – a pianist with bass and drum backing – to an equal partnership of the three diverse instruments. To put such a combination together required him to find musicians of equal creativity and understanding, and he found them when he formed his first regular trio with the brilliant Scott LaFaro on bass and Paul Motian on drums. In a short period that band made four superb albums (two in studio, Portrait in Jazz and Explorations, and two live, Sunday at the Village Vanguard and Waltz for Debby). Astonishingly, the music for the two live albums was recorded on the same day, 25th June 1961.

Just when it seemed a wonderful future was opening up for the trio, tragedy struck. Bassist Scott LaFaro was killed in a car accident, just 10 days after the Village Vanguard date. Evans was completely devastated by this event, so much so that he stopped playing completely for several months. He was paralysed by grief. For a man whose whole life revolved around playing the piano this was an indication of the depth of the bereavement he felt. It also made Evans sink even deeper into the heroin habit he was already struggling with.

The film focusses on the the period after LaFaro’s death, when Bill Evans stays in New York City with his brother Harry (who was also a musician) before his escalating drug use forces him to leave in order to detox with is parents in Florida. It’s essentially a portrait of a man’s struggles with grief and his inner demons, and is at times grim but it is keenly felt and very absorbing. Bill Evans was a shy and introverted man who found his own talent hard to cope with, and was consequently very insecure, but the film does not try to turn him into some kind of martyr. Neither does it try to come up with a glib “explanation” of his heroin addiction. Like the complex harmonic progressions that abound in the music, not everything has a straightforward resolution. The honesty of the film is one of its greatest strengths.

The look of the film is very “art house”. Shot (mostly) in stark black-and-white (see the trailer), it makes striking use of light and shadow. In places it reminded me a lot of Night of the Hunter. Another interesting thing is that although it is set largely between New York and Florida, it was actyually shot in Ireland!

Mark O’Halloran’s script avoids a linear narrative, instead jumping backwards and forewards, giving the story a dreamlike quality. For example, flash-forwards to the 1970s are shot in vibrant saturated colour to contrast with the monochrome of the rest of the film. These sequences are previews of yet more tragedy in Evans’s life: the deaths by suicide of his partner Ellaine Schultz in 1973 and his brother Harry Evans in 1979. Bill Evans himself passed away in 1980.

Finally I have to take my hat off to Norwegian actor Anders Danielsen Lie for his utterly compelling performance as Bill Evans. I can’t think of many examples of an actor so completely inhabiting such an enigmatic role. I suppose he was helped because there are quite a few examples of Evans playing and talking on film, but even so it was a standout performance.

Everybody Digs Bill Evans is highly recommended, and not only for jazz fans! It’s showing at The Lighthouse and the Irish Film Institute in Dublin.

P.S. The title of the film is the same as that of a studio album made by an earlier manifestation of the Bill Evans Trio, with Sam Jones on bass and Philly Joe Jones on drums, before he teamed up with Scott LaFaro and Paul Motian.

P.P.S. Since Autumn is coming on, here’s my favourite track from Portrait in Jazz with Bill Evans, Scott LaFaro and Paul Motian showing what they could do.

Weekly Update from the Open Journal of Astrophysics 19/09/2026

Posted in OJAp Papers, Open Access, The Universe and Stuff with tags , , , , , , , , , , , , , , on September 19, 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 seven papers, bringing the number in Volume 9 (2026) to 209 and the total so far published by OJAp up to 656. This is the second week running that we have published 7 papers.

I continue to include the posts made on our Mastodon account (on Fediscience); these announcements also contain a clickable form of the DOI for each paper. Our Mastodon account has regular updates and other announcements from OJAp too.

The first paper this week was published on Monday 14th September in the folder Cosmology and Nongalactic Astrophysics. The title is “The Power of DESI for Photometric Redshift Calibration: A Case Study with KiDS-1000” and it is by Diana Blanco (UC Santa Cruz, USA) and 66 others distributed internationally. This study explores using the Dark Energy Spectroscopic Instrument (DESI) to calibrate photometric redshift distributions for gravitational lensing, which could improve understanding of dark energy and cosmic structure. In fact this paper was ready for publication a few months ago, but the first author left for another job before putting the final version on arXiv so it took a while to finish it.

The overlay for this one is here:

That concludes this week’s update. At the rate we’re going we could well reach 300 by the end of the year, but we’ll just have to wait and see about that. I’ll do another next weekend.

My Brother Made Me Gay!

Posted in Biographical, LGBTQ+ with tags , on September 18, 2026 by telescoper

My attention was drawn yesterday to an article in New Scientist with the following introduction:

You would think I would have known about the fact that men with older brothers are more likely to be gay, but this was news to me. The Fraternal Birth Order Effect does seems to have been well established since its discovery in the 1990s. The explanation proposed at the time attributed the effect to a prenatal biological mechanism, as the association is only present in men with older biological brothers, and not present among men with older step-brothers. Hypothesized to be the result of a maternal immune response to male foetuses, whereby antibodies neutralize male Y-proteins thought to play a role in sexual differentiation during development, it would leave some regions of the male brain in the ‘female typical’ arrangement – resulting in attraction to males.

The origin of the effect seems plausible to me, though I’m not an expert on such matters. I have no idea why it has taken 30 years to find a similar effect with older sisters. In the interest of full disclosure, I should state that I have an older brother and no other siblings.

My worry with studies like this is not their scientific validity but the use that others may make of the findings. In the wrong hands, this feature of pre-natal development could easily be presented as some sort of defect, leading to all kinds of nasty ideas about how to “correct” it.

Being Emergency Ready

Posted in Biographical with tags , on September 17, 2026 by telescoper

This booklet was delivered to my house this week. It is also available to download here. It is from a Department that I didn’t know existed called the Office of Emergency Planning (“An Oifig Pleanála Éigeandála” as Gaeilge). This Goverment does seem to be good at creating emergencies, but I hadn’t realised until now that they were planned.

Here is the intro…

From storms and power cuts to flooding and health emergencies, Ireland can experience a range of emergencies. Planning ahead and taking simple steps can help reduce disruption.

Find out how you and your household can prepare as part of the Be Emergency Ready campaign.

I suppose the advice in it is sensible, as far as it goes, but the sorts of emergency it lists are very difficult to be ready for. For example, under “Food” it says “Keep a supply of non-perishable food on hand”. It doesn’t give examples, incidentally, but presumably a list could include dried pasta, rice, noodles, breakfast cereals, canned goods (soups, tinned tuna, baked beans, etc), preservatives (jam, marmalade, etc) and and tea andcoffee, jam. I suppose you should also have dried milk or UHT milk (if you can stand it), though Oat milk does keep for a long time on the shelf. The problem is that many of these are useless if you don’t have a power supply to your cooker, kettle, microwave or other cooking equipment. I have lost power in my house many times since I moved here, although never for more than 24 hours.

Lack of water might also make cooking tricky. Talking of which, the hosepipe ban in Ireland which began in August has now been lifted. This morning, to celebrate, Uisce Éireann switched off the water supply to my house (which it has done several times over the last month). This is to carry out “essential works” to replace pipes, etc. I understand the need for these, of course. I have signed up to receive SMS alerts when disruption is expected but the actual disruption rarely happens on the date referred to in the alert, which is worse than useless. Today, however, it was on the right day.

Anyway, under “light and heat” it doesn’t mention using candles, a stock of which I do keep in the house. I learned this lesson during the Three-Day Week in 1974.

No power also means no internet access so perhaps I should prepare an emergency blog post to put up in case of emergency? Other than that, following the booklet’s advice to “Make a Plan”, I propose to stay in bed and sleep until the calamity is over, if necessary for weeks, if necessary alone.

Now back to the real emergency: teaching starts on Monday and I can’t get my Moodle page to work!

18 Years In The Dark

Posted in Biographical, The Universe and Stuff with tags , , , , on September 15, 2026 by telescoper

Today is another anniversary. I just received the following message from WordPress.com reminding me that today is the 18th anniversary of my registration with them, which is when I took my first step into the blogosphere. That was way back on 15th September 2008…

I suppose this means that this blog is an adult now!

I actually wrote my first post on the day I registered but, unfortunately, I didn’t really know what I was doing on my first day at blogging – no change there, then – and I didn’t actually manage to figure out how to publish this earth-shattering piece. It was only after I’d written my second post that I realized that the first one wasn’t actually visible to the general public because I hadn’t pressed the right buttons, so the two appear in the wrong order in my archive. Such was the inauspicious beginning of this “shitty WordPress blog”!

Since then I have published 7,846 blog posts posts (including this one), which have altogether received over 6.1M page views from 2.6M unique visitors. That doesn’t include the 2000+ subscribers who receive posts by email nor those who view the federated version via the fediverse. The largest number of hits I have received in a single day is still 8,864 (in 2014, at the peak of the BICEP2 controversy).

My First Paper, 40 Years On…

Posted in Biographical, The Universe and Stuff with tags , on September 15, 2026 by telescoper

Today is the 40th anniversary of the publication of my first ever scientific paper!

Here is the front page:

mnras_paper

This was before the days of arXiv so there isn’t a copy on the preprint server, but you can access the whole article here on NASA/ADS.

All right. I know it’s a shitty little paper. But you have to start somewhere!

I’m particularly sad that, looking back, it reads as if I meant to be very critical of the Kaiser (1984) paper that inspired it. I still think that was a brilliant paper because it was based on a very original idea that proved to be enormously influential. The only point I was really making was that a full calculation of the size of the effect Nick Kaiser had correctly identified was actually quite hard, and his simple approximation was of limited quantitative usefulness. The idea was most definitely right, however.

I was just a year into my PhD  DPhil when this paper came out, and it wasn’t actually on what was meant to be the subject of my thesis work (which was the cosmic microwave background), although the material was related.

This paper provides two excellent illustrations of what a good supervisor John Barrow was. I was a bit stuck with the project that John had assigned me and eventually admitted to him that I was having problems getting anywhere. I thought he’d assume I was useless and suggest that someone else should supervise me. But no. He said he realised it was a hard problem and sometimes it’s good to think about something else when you’re stuck. So he asked me to look at cluster clustering for a bit. I told him what I found and he said I should write this up as a paper, which I did. Most importantly however the trick I used in simplifying the calculations in this paper turned out to be applicable to the first problem, hotspots in the cosmic microwave background, which led a success in the project and to my second paper. We were both delighted that everything turned out well with that original project.

My original draft of this first paper had John Barrow’s name on it, but he removed his name from the draft (as well as making a huge number of improvements to the text). At the time I assumed that he took his name off because he didn’t want to be associated with such an insignificant paper, but I later realized he was just being generous. It was very good for me to have a sole-author paper very early on. I’ve taken that lesson to heart and have never insisted on putting my name on my students’ work.

Further Thoughts of Retirement…

Posted in Biographical, Maynooth with tags , , , , on September 14, 2026 by telescoper
What we call the beginning is often the end
And to make and end is to make a beginning.
The end is where we start from.

from Little Gidding, Four Quartets, by T.S. Eliot.

The start of teaching for 2026/7 is approaching at an alarming rate. new and continuing students are registering and today we had a staff meeting in the Department of Physics about arrangements for the new term. This all made me think again about retirement.

About three years, while I was in Barcelona on sabbatical , I posted an item about looking forward to retirement. Here is an excerpt from that piece:

The fact of the matter is, though, that I can’t afford to retire yet. I have a mortgage to pay and I’ve only had five full years of pensionable service in the Irish system, so won’t get much of a pension. I have the frozen residue of my UK pension, of course, but that is subject to an actuarial reduction if I take the benefit before I’m 65, which is also the standard retirement age for academic staff in Ireland. I can’t be made to retire here until I’m 70, in fact, but I think I’ll be well beyond my best-before date by then and am not keen to overstay my welcome.

So it looks like I’ll have to stay until I’m 65 at the earliest. In fact I won’t be able to collect the State Pension (SPC) until I’m 66, so I’ll probably have to stay until then. That means that when I get back from sabbatical I will have four or five years left until I can retire.

Since I posted this I made a firm decision that I will retire as soon as I’m able, which should be in June 2028. Having sold my old house in Cardiff some time ago, I have paid off my Maynooth mortgage which makes the financial situation much simpler. I am now quite confident that I can afford to retire before I’m 66.

I know many academics don’t like the idea of retiring. I suppose that’s because they’re afraid they won’t know what to do with their time. I’ve never felt like that. I’ve always had plenty of outside interests, but now there’s another factor. As I alluded to in an earlier post, and contrary to all my expectations of three years ago, there is another person involved. That person, whose name I won’t reveal, graduated this summer from an unnamed university, and is just about to embark on a two-year Masters degree (in a subject not to be disclosed) in a location I won’t tell you about. He will be finishing that course in the summer 2028.

For the next two years things for us will be pretty much as they are now: not living together, but spending as much time in each other’s company as possible at weekends and holidays. That arrangement suits us both very well in the current circumstances but we have already started discussing plans beyond the two-year horizon. Some of these are not at all serious, but amusing to think about. Others would be fantastic if they turned out to be possible. We have the best part of two years to decide what to do. In any event, I find it exciting to be able to think seriously of retirement as a beginning as well as an end.

Picture Post

Posted in Politics with tags , , on September 13, 2026 by telescoper

I couldn’t resist posting these two hilarious pictures of Donald Turnip’s visit to the Áras an Uachtaráin in Phoenix Park yesterday to meet the President of Ireland, Catherine Connolly. Her expression in the first picture is priceless, and the second one looks like she sent him away with a flea in his ear.

It seems that Trump said that he “would love to see” a united Ireland, which is quite a surprising statement to come from an Orange Man…
