Sydney, Ten Days in

Posted in Biographical with tags , , on February 14, 2024 by telescoper

Taking a few moments over breakfast to post about life in Sydney. This morning is cooler than it has been for a while and it’s all a bit rainy. It was very warm (by my standards) earlier in the week (up to 31°C) and very humid, culminating in thunderstorms but those were some way off in the distance so didn’t affect us greatly. Since then it’s been in the mid-20s with a mixture of clouds, light rain, and sunshine. You have to be careful here, though, as it is perfectly possible to get sunburn when it’s cloudy. I’m definitely glad I brought my hat.

Other than the weather, the main thing at the University is that it’s Orientation Week, when the new students arrive. Campus has been much busier this week than it was last week, as you can see from the pictures above; I wanted to stand in the same spot for the second picture but there were too many people. Lectures start next week, for both new and returning students, so it should get even busier.

I’ve managed to book tickets for two different performances at the Opera, The Magic Flute and La Traviata. These weren’t cheap but I couldn’t resist seeing the Sydney Opera House from the inside. I’m also planning a trip to the Art Gallery of New South Wales, were there is a special exhibition of art by Wassily Kandinsky which I must see. I’m also going to travel around a bit to give a few talks in the Sydney area.

My diary is filling up, so the second half of this visit will be rather busier than the first, but it should all be interesting!

Supermarket Sweep

Posted in Biographical with tags , , on February 11, 2024 by telescoper

Since I’m in a self-catering apartment here in Sydney, I’ve needed to scout out the local shops. It turns out the nearest supermarket to my residence is called Coles. When I was buying a few bits and bobs there I showed the name on my debit card to the person at the checkout, but they wouldn’t even give me a discount.

Coles is one of the two big supermarket chains in Australia, the other being Woolworths. I was a bit surprised by that as the UK Woolworths went down the tubes some time ago. I’ve tried both stores during my stay here and it pains me to say that I think Woolworths is the better of the two; it also has the highest market share. There’s also an Aldi near me.

One thing that surprised me about both Coles and Woolworths is that neither sells alcoholic beverages while Aldi does. It turns out that both have associated drinks businesses, Liquorland and BWS respectively, usually located right next to the supermarkets. For some reason it has been decided to keep them separate from the general stores. That might be because of licensing laws or because of purely commercial reasons. I’ve sampled a couple of wines while I’ve been here (one red and one white, both mid-price) and both were nice. Imported wines are available, but I’ll be sticking to local producers while I’m here. Of course the grape varieties are of European origin, but grown in Australia: the red I tried was a Montepulciano and the white a Riesling.

Other than that the main difference between supermarkets here and in Ireland (or the UK) is the much greater selection of Asian food and ingredients. Most groceries are of Australian origin, though, and even brands that are familiar back home (e.g. Heinz) are generally made here under licence. Anyway, I didn’t come all the way here to eat what I would eat at home, and it’s been fun sampling some of the local delicacies, such as Barramundi. I haven’t had kangaroo yet. I did try a Tim Tam but was unimpressed.

Walkabout in Sydney

Posted in Biographical with tags , , , , , on February 10, 2024 by telescoper

It was a bit rainy this morning so my planned Saturday walk around Sydney was a bit truncated. I made it to Sydney Harbour but didn’t go on a boat trip, which I’ll do later. I didn’t have time to visit the Botanical Gardens or the Art Gallery of New South Wales, which are nearby, but will do so later. I was planning to take more pictures with my little compact camera too, but when I took it out I realized its battery was virtually flat and I had to use my phone camera instead. The light here is very different from Ireland! Fortunately I’m here long enough that I’ll have other opportunities for exploration.

My residence in Sydney is the district called Ultimo, which is very central and close to the University of Sydney campus. There is excellent public transport from here to Circular Quay, close to both the Sydney Harbour Bridge and the Opera House, but I needed to stretch my legs so took a leisurely stroll of about an hour, my route taking me through Haymarket and Chinatown to Circular Quay. It being Chinese New Year, I took a detour to look at some of the preparations for two weeks of celebrations. I enjoyed the walk, which followed the tram line most of the way there, and it was getting rather warm in late afternoon so I returned by tram.

Anyway, after much fiddling about, I’ve managed to embed a video I put on Instagram. As you can hear, it was quite windy!

P.S. Here’s an interesting factoid for you: the population of Greater Sydney (5.3M) exceeds that of the entire Republic of Ireland (5.0M).

Sydney Calling…

Posted in Biographical with tags , , on February 7, 2024 by telescoper
Zoom calls from Australia are awkward

I know that’s an obvious joke, but I couldn’t resist.

The thing that’s really awkward about Zoom calls from Australia is when the other attendees are in Europe and North America. I had to chair a (Euclid-related) telecon in the early hours of yesterday morning, which wasn’t much fun, though I think it went OK and I did manage to get some sleep afterwards.

Other than that I’ve been remarkably free of jet lag. I had received dire warnings from other colleagues who have made the trip, but it doesn’t seem to have affected me badly at all. By now I’m used to what time it is, though I still have problems with what day it is. That’s because most of the emails I get are sent from Europe and these are generally sent yesterday (my time), i.e. from a place where my today is the sender’s tomorrow. If somebody says “let’s chat tomorrow” that confuses me!

Although I haven’t had much trouble with the time difference, the one thing that I have taken time to adjust to is eating habits. I got on the plane at Abu Dhabi at 10.25pm and once the plane had reached cruising altitude they served dinner (and, of course, wine). The trouble is that was around 7am Sydney time when I should have been having breakfast. I arrived in Sydney around 7pm Sydney time, when I should have had dinner, but all I had was a craving for breakfast (especially coffee). Obviously my stomach wasn’t yet tuned in. Anyway, just two (or is it three?) days later, I’m back to having breakfast at breakfast time and dinner at dinner time so all is well.

University of Sydney, Physics, and Astronomy…

Posted in Biographical, History with tags , , , , on February 7, 2024 by telescoper

Here’s a gallery of random pictures I took on the way to the Physics Department at the University of Sydney this morning.

The academic year at the University of Sydney is about to start, with the new intake of students beginning to arrive next week and the first lectures taking place the week after that. The rows of tents are for the various student societies which will be hoping to recruit new members. The University was founded in 1850 and the architectural style of the older buildings on campus is what you might call Victorian Gothic Revival. There are also buildings dating from the 1920s, such as the Faculty of Medicine (1922) and the Physics Building (1924); the latter seems much bigger on the inside than the outside, and also has a new building next to it devoted to nanoscience.

I’ve posted before about the famous optical instrument manufacturer, the Grubb Telescope Company, founded in Dublin by Thomas Grubb and later renamed Grubb Parsons after its relocation to Newcastle upon Tyne. I’ve posted about other connections too, including the presence in the Physics Department in Barcelona of a refracting telescope made by Grubb. Imagine my surprise, then, when I saw yet another Grubb Telescope near the entrance to the Physics building of the University of Sydney, this one made in 1893. This is further evidence – as if it were needed – that, in its time, the Grubb Telescope Company really was the world leader in optical instrumentation.

P.S. The later manifestation of the Grubb Telescope Company – Grubb Parsons – also has Australian connections, including making the primary mirror for the Anglo-Australian Telescope (AAT) and building the UK Schmidt situated next to the AAT at Siding Spring Observatory (about 500 km from Sydney).

Arrived Down Under

Posted in Biographical with tags on February 5, 2024 by telescoper

The plane from Abu Dhabi to Sydney set off a bit late but, 13 hours later, arrived slightly ahead of schedule in Sydney at about 7pm local time. I hadn’t quite realized how much of the flight is actually across Australia itself. It’s quite a big place. Who knew? The route took us over Sri Lanka, incidentally.

Australian immigration and customs were a bit of a rigmarole but didn’t really take all that long and once through I took a taxi to the hotel where I’ll be stating for the next month or so. I have a self-catering suite, which is very nice so I’m looking forward to my stay here.

It’s warm in Sydney – about 26° when I landed – but a bit overcast and very muggy. Rain is forecast.

Today is a public holiday in Ireland, the first Monday on or after 1st February. Astronomically speaking this cross-quarter day is about half-way between the Winter Solstice and the Spring Equinox in the Northern Hemisphere. Here of course it’s between the Summer Solstice and the Autumn Equinox, which takes place at the beginning of August in the Northern Hemisphere and is in Ireland sometimes referred to as the start of Autumn. The climate here in Sydney is very different from Ireland, however, and I don’t think anyone thinks of 1st August as Autumn.

Anyway, the flight went really well. I even slept for a few hours so I’m not particularly tired, but I’m still 11 hours out of kilter so I’ll try to stay up as long as possible and get a good night’s sleep to try to reset my internal clock. I plan to go for a walk tomorrow morning to explore my immediate surroundings then head up to the University campus to say hello to Physics Department.

In Transit

Posted in Biographical with tags , on February 4, 2024 by telescoper

So here I am in Abu Dhabi International Airport. It’s about 8.40 pm my time, which is about 4.40 pm GMT. I’ve decided to take the so-called “silly” route to Barcelona to resume my sabbatical (via Sydney Australia), and Abu Dhabi is the first staging post along the way. The flight so far – with Etihad – has been pleasant enough: on time, and with nice food and wine. I wasn’t sure about the in-flight entertainment though. That seemed to consist of a very long cartoon showing a very large aeroplane moving very slowly over a map. Still, there was some nice music to listen to, including some jazz and several Schubert piano sonatas and I’ve got plenty to read.

The first leg was about 7 hours or so, which isn’t too bad. The next bit is almost twice as long and there’s another +7 hrs in terms of time difference. I’m not sure what state I’ll be in when I get to my final destination but I’ll find out by about 7.30pm Sydney time tomorrow.

I’ll update when I get to the other side!

On Imbolc and the Quickening of the Year

Posted in Biographical with tags , , , , , on February 1, 2024 by telescoper

It is 1st February 2024, which means that today is Imbolc, a Gaelic festival marking the point halfway between the winter solstice and vernal equinox in the Northern hemisphere.  Incidentally, the Celts counted each day starting from sunset so Imbolc really started yesterday evening, on 31st January.

In the old pagan calendar, this day is regarded as the first day of spring, as it is roughly the time when the first spring lambs are born, daffodils, etc, start to appear, and the days get noticeably longer.  It is also sometimes called, rather beautifully, The Quickening of the Year.  It’s a time for rebirth and renewal after the darkness of winter.

In the Northern hemisphere, in astronomical terms, 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 the cross-quarter days, of which Imbolc is one. They are:

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

The names I’ve added in italics are taken from the Celtic/neo-Pagan and, in parenthesis the (English) Christian terms, for the cross-quarter daysThese 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 that although the Pagan festivals have been appropriated by the Christian church, they have much older origins. In Ireland Imbolc is usually often referred to a Lá Fhéile Bríde,  St Brigid’s Day, after St Brigid of Kildare, whose Feast Day is 1st February, another appropriation of a much older festival.

Until last year only three of the four cross-quarter days were associated with public holidays in Ireland; there wasn’t a holiday for Imbolc. In 2022 however, the Government decided to create a new Bank Holiday that corrected this anomaly by introducing a new St Brigid’s Day holiday on the first Monday on or after 1st February, which also happens to be the first national holiday in Ireland to be named after a woman. The first such holiday was Monday, 6th February 2023 and the second is on Monday 5th February 2024, by which time I will hopefully be in a place where Northern hemisphere considerations do not apply.

P.S. On a personal note, today is also the 6th anniversary of the very first lecture I gave in Maynooth, on Computational Physics on 1st February 2018…

A Strange Dream

Posted in Biographical with tags , , on January 26, 2024 by telescoper

From time to time on this blog I’ve written about dreams that I’ve had (e.g. here and here). I find dreams rather fascinating but most times when I wake up I don’t remember enough about them to write coherently about. This week, though, I’ve been troubled by a dream I had a few days ago the memory of which has stayed in my brain.

For background, I have had a bit of a cold recently. It’s been nothing serious but has disturbed my sleep a bit and I have dreamt more than usual. One dream, of which I remember only a small part, involved my house being invaded by giant tortoises. Bizarre as that sounds, The Invasion of the Giant Tortoises, didn’t bother me as much as the one I will try to describe now…

In this dream I am at an academic conference of some sort. I am recognized by other people there, attend some talks in lecture theatres, socialize at coffee breaks, join a social dinner, and even go on an excursion by coach with other attendees through a beautiful landscape of mountains, forests and castles.

Nothing particularly weird about that, I suppose. The strange thing is that everywhere I go at this event I have a companion in the form of a young man who is blind. This boy is about twenty to twenty-five years old, with light blond hair, shorter than me, well built and pleasant-looking. His eyes are partly closed and permanently cast to one side. I don’t know his name.

I arrive at the conference with this boy’s arm linked through mine. I sit next to him at talks, sometimes whispering a description of what’s shown on the slides. I get him coffee. When we go to another lecture room we go arm in arm. During the excursion I sit next to him and describe what I can see. He smiles and nods in response. I notice other people looking at us with somewhat patronizing expressions.

Eventually, as dreams do, this all dissolves into some other sequence which I don’t remember. That’s it.

So why do I find this apparently rather innocuous dream so troubling?

The first reason is the identity of the young man. Although I would recognize him if I saw him, as far as I can recall, his face is not one that I’ve ever seen before. Perhaps he is someone I knew a long time ago, or perhaps my subconscious has created a fictional character! His age suggests he might be a student. I have taught blind students before, but I remember them all and he doesn’t resemble any of them. The last time I had a blind student in my class was at Sussex, and I did walk around with him sometimes holding my right arm, e.g. when there were tricky stairs, and was happy to be helpful in that way, but he looked nothing like the boy in the dreams.

More disturbing (to me) than the identity of my sightless companion, however, is what on Earth this dream actually means? Why do I have this boy with me all the time? What does his presence signify? Is it some sort of reference to my sexuality? Nothing at all obviously sexual happens in the dream, by the way, in case you were wondering. I really have no idea how to interpret this!

At this risk of eliciting some strange responses, anyone who has any ideas is welcome to suggest them through the comments box!

UPDATE: An old friend emailed me to say give his interpretation: that a cute blond boy would have to be blind to want to go out with me. Thank you for that.

DIRAC Research Image Competition Winners

Posted in Art, Biographical, The Universe and Stuff with tags , , , , on January 18, 2024 by telescoper

You may recall that last year I posted about the results of the annual Dirac Research Image competition for which I was one of the judges. For those of you who weren’t aware, DIRAC is a high-performance computing facility designed to serve the research community supported in the UK by the Science and Technology Facilities Council (STFC). I was honoured to be invited back to judge the competition this year.

As before, entries to the Research Image Competition were divided into two Themes: Theme 1 (Particle and Nuclear Physics) and Theme 2 (Astronomy, Cosmology and Solar & Planetary Science) and scores were allocated by the judges based on visual impact and scientific interest. Once again, the standard was very high, but there were clear winners in each category. Here they are:

LUCA REALI, MAX BOLEININGER, DANIEL MASON, SERGEI DUDAREV (UKAEA)

DATA INTENSIVE CAMBRIDGE

Molecular dynamics simulations of high-dose radiation damage in tungsten to understand the evolution of the material under fusion reactor conditions. Blue spheres are vacancies (missing-atom defects), orange spheres are interstitials (extra-atom defects). Lines are dislocations (linear crystallographic defect).

Softwares: LAMMPS for simulations, Ovito for the rendering.

JOSH BORROW, FLAMINGO TEAM

MEMORY INTENSIVE DURHAM

The most massive galaxy cluster in the flagship, 2.8 Gpc, FLAMINGO volume, with each side of the image spanning 40 megaparsecs. Each colour represents a different gas density contour, highlighting the extremely complex spatial and velocity structure of the gas within the cluster. At the center, the gas serendipitously aligns to produce a love heart.

The image was created with DiRAC supported software SWIFT and swiftsimio.

For more details about these images and the other entries see here. The 2024 Dirac Calendar features a selection of the entries.

Congratulations to the winners and indeed all the entrants!
