Four Years On…

Posted in Biographical with tags , , on January 31, 2017 by telescoper

After the annual last-minute rush to file my tax return by the  deadline (which is midnight today, 31st January),  I can now relax not only because the job is finished, but also because it confirms that I am due a rebate (as indeed I was last year).

Anyway, thinking about the 31st January deadline made me remember that it was precisely four years ago, on 31st January 2013, that I left Cardiff University to take up a post at the University of Sussex. On that occasion I had to rush to finish marking a big stack of exams and finish packing the books in my office before signing the work of art I had left on my whiteboard and heading off.

I started at Sussex the following day.

I didn’t think then that in four years I would be back in Cardiff, but then I didn’t think a lot of things would happen that have happened in that time. I don’t regret my decision to resign, but I do find myself from time to time wondering how things are going back at Sussex and how things might be now had I decided to stay there. I’ve been so busy I’ve only been back once to Brighton since I left last summer. I must put that right. Perhaps I’ll have a holiday there in the spring.

Back to the (Early) Universe

Posted in Education, The Universe and Stuff with tags , , , on January 24, 2017 by telescoper

After what seems like ages away from the lecture theatre, today I resuming teaching duties with the first session of my module on The Physics of the Early Universe; the link there gives Enzo Pascale as being in charge of the module, but he has left BrExit Britain for his native Italy so I’ve taken his place. I actually wrote the syllabus for this module about five years ago when I worked in Cardiff previously, and was scheduled to deliver it in 2013, but I left for Sussex before it started and never actually lectured it. It’s nice to be able to teach this material at long last – at least it’s stuff that I should know something about.

This lectures are attended by students on the 4th year of the integrated Masters programme (MPhys) and also on stand-alone MSc courses in Physics or Astrophysics. I have about 25 students enrolled, which is not bad for a specialist module.

In fact Enzo recommended the book I wrote with Francesco Lucchin when he taught the module, and I’m happy to use it as the main text. I won’t cover all the material in the book – there isn’t time, and some of the book is out of date (written in 2002) – but at least almost everything I do in the lectures has a counterpart in the book.

Chapter 3 of Coles \& Lucchin has a chapter that may prove particularly popular in this era of ‘Alternative Facts’:

cosmology

I did however resist the temptation to hire a group of people to sit at the front of my first lecture cheering and clapping wildly.

I’ve asked to have my lectures timetabled in two-hour chunks. That’s partly because I only work part-time and I wanted to be able to maximize the flexibility with which I can use the rest of the time by concentrating my teaching commitments. The other reason is that I like the extended format. I don’t talk continuously for the whole time, of course. That would be unbearable for me and for the students. We have a ten-minute break in the middle. However, the two-hour block allows a wider range of activities – lecturing, discussion and worked examples – which is harder to do in the usual (50-minute) slot without being excessively rushed. When I taught postgraduates at Queen Mary we used two-hour blocks, which worked out quite well. The only problem is that I’m now a lot older, and having finished my first double-lecture I think it’s fair to say I’m more than a little knackered.

Another innovation is the use of Cardiff’s new lecture-capture system (called Panopto), which allows the lecturer to record everything – powerpoint, data visualizer, whiteboard and live action – for posterity. I recorded this morning’s lecture in toto and at some point when I get a moment I’ll do a quick edit and put it on Learning Central for the students to view at their leisure. I’m not sure how useful my ramblings will prove to be, but it’s fun to try these things. It’s a significantly more sophisticated and flexible system than the one we used when I was at Sussex, and I’m also lucky to be in a nice, clean and recently refurbished lecture theatre…

Anyway, this gives me the excuse to refloat an old opinion poll about lecture capture. Such facilities are of course very beneficial for students with special learning requirements, but in the spirit of inclusive teaching I think it’s good that all students can access recorded lecture material. Some faculty are apparently a little nervous that having recordings of lectures available online would result in falling attendances at lectures, but in fact the available evidence indicates precisely the opposite effect. Students find the recorded version adds quite a lot of value to the “live” event by allowing them to clarify things they might not have not noted down clearly.

I like the idea of lecture capture a lot and am very happy to do it with my own lectures. It does seem to be the case however that some university staff are wary of this innovation, but opinion may be changing. Please let me know what you think via the poll:

If you don’t like the idea I’d welcome a comment explaining why. I’d also be interested in comments from colleagues in other institutions as to the extent to which lecture capture technology is used elsewhere..

 

Studying Physics & Astronomy at Cardiff University

Posted in Biographical, Education with tags , on January 9, 2017 by telescoper

I just came across this video (featuring, among others, my colleagues Haley Gomez, Carole Tucker and Chris North) advertising the School of Physics & Astronomy at Cardiff University. Since the annual recruitment cycle gets properly under way at this time of year I thought I’d share this here for the benefit of prospective students. We had a record intake last year, for both undergraduates and postgraduates. With outstanding successes in research over the past year (including the discovery of gravitational waves and the opening of a new venture in compound semiconductors) there’ll hopefully be a lot of interest again this year! We’re a friendly lot here, and Cardiff is a great city to live in, so why not get in touch?

Back to Work…

Posted in Biographical, The Universe and Stuff with tags , , on January 3, 2017 by telescoper

Well, the Christmas break is over at Cardiff University and I’m back in the office of the Data Innovation Research Institute. To be honest, it’s rather quiet around here. Most staff seem to be still on holiday. There are a few students around, mainly international ones. This is actually a revision week at Cardiff University in advance of the mid-year examinations which start next week and go on for a fortnight. After that we’ll be back into teaching. I’ll be doing a Masters-level module on The Physics of the Early Universe in the forthcoming term, and I’m very much looking forward to it.

The outcomes of the annual round of consolidated grants administered by the Astronomy Grants Panel of Science and Technology Facilities Council were announced just before Christmas, with success for some and disappointment for others. I only have anecdotal evidence from personal contacts but it seems to have been a tough round, which wouldn’t surprise me because the funding for basic scientific research in the UK has been flat in cash terms for many years now, and is gradually being eroded by inflation. It’s a tough climate but when, in a couple of years, we lose access to all forms of EU funding things will get even tougher…

Anyway, as new grants are announced and old ones terminated, this is a busy time of year for postdocs (who are largely funded by research grants) seeking new positions. I’ve spent most of the day so far writing references for applicants and will return to that task for a couple of hours after lunch. It’s particularly tough on those whose positions lapse at the end of March who only got notice just before Christmas that their existing funding is not going to be renewed. There’s little time in such a position to get a new job sorted, but on the other hand, new grants are starting from 1st April so there are opportunities out there. It’s not easy to respond if you have a family or other commitments, though.

Another thing that happened just before Christmas was that the Data Innovation Research Institute here at Cardiff University announced its first tranche of “seedcorn” grants to foster interdisciplinary research. These grants are quite small in cash terms but it is hoped that at least some of them will help develop substantial projects by bringing together parts of the University that don’t previously collaborate enough. Congratulations to those whose proposals were selected, and commiserations to those who were unsuccessful.

I was pleased that my proposal – together with Professor Nikolai Leonenko of the School of Mathematics – was one of the successful bids. That means that, probably in the spring, we will be organizing a short workshop relating to the analysis and modelling of astrophysical data defined on the sphere, a topic which has interesting mathematical aspects as well as very practical implications for astronomy and cosmology. We’ll be starting to organize that soon, which adds another item to my to-do list, but it should be a fun conference when it happens.

Before you ask: yes, I do work for the Data Innovation Research Institute but because I was an applicant I recused myself from judging the applications in case there was any perception of a conflict of interest. So there.

Most of my work between now and the start of teaching term is going to be devoted to a couple of MSc courses we’re planning to launch this year, but I’ll write more about them – and plug them shamelessly – when they’re all formally announced and ready to go!

And with that I’d better get back to work again.

Infinite LIGO Dreams

Posted in Art, The Universe and Stuff with tags , , , , , on November 28, 2016 by telescoper

There was a special event in the School of Physics & Astronomy here at Cardiff University on Friday afternoon – the unveiling of a new work of art in our coffee area. The work, a large oil painting, called Infinite LIGO Dreams by local artist Penelope Rose Cowley was inspired by the detection of gravitational waves earlier this year:

You can read more about this work, and the circumstances behind its creation, at the Cardiff University website and via the Physics World blog. If you like the piece you can order a poster-sized print from Penelope Cowleys’s own website here.

The unveiling of this artwork was preceded by a drinks reception, which probably accounts for the errors that crept into the blog post I wrote on Friday after the party!

 

Cardiff: Centre of Gravity

Posted in The Universe and Stuff with tags , , , on November 17, 2016 by telescoper

It’s a very busy period for me as the Cardiff University Data Innovation Research Institute (DII) gears up for some exciting new activities in both teaching and research (of which more in due course) and embarks on is strategy for promoting and fostering interdisciplinary research across Cardiff University and beyond.

Yesterday, however, I attended an informal meeting in the School of Physics & Astronomy at which we had an update about other strategic developments in the Gravitational Physics Group, some of whose members work in the DII Following on from the first-ever detection of gravitational waves earlier this year the group has ambitious plans to build on its involvement in this discovery. Here’s a nice short video produced by Cardiff University that discusses this discovery:

 

 

Cardiff University has supported research on gravitational waves for a very long time, and it is important that it reaps the benefit now that its investment is starting to pay off. To rest on laurels at this stage would be to risk losing the benefits of that sustained investment. It was very exciting to hear about the group’s plans for further sustained expansion, which will make the Cardiff one of the leading centres of gravitational wave research  in the world.

I’ve already mentioned on this blog that a couple of new positions have already been advertised, one in gravitational wave astronomy (to consolidate existing activities in theory and data analysis) and the other in a completely new area of Gravitational Wave Experimentation. Those advertisements have now closed and the process of filling the vacancies is under way.

However, yesterday we heard of even more expansion of gravitational physics research, in the form of a new academic position in Time Domain Astronomy with particular emphasis on transient sources of electromagnetic radiation that could be associated with gravitational wave production (such as gamma-ray bursts). I’ll post the advertisement on this blog when it is available. And that’s just the start: further positions will be released over the next few years which will turn Cardiff into a true Centre of Gravity.

Exciting times!

The Last Post – Cardiff University Remembers

If you think a lot has happened since July 1st this year, pause a moment to reflect on the fact that 100 years ago today the Battle of the Somme was still raging.

 

Lest we forget.
