A Clean Sweep For Team MPS

Posted in Education, Sport with tags , , on June 19, 2014 by telescoper

It is with great pleasure that I announce another outstanding result for the School of Mathematical and Physical Sciences (MPS). While minor unexciting sporting contests go on elsewhere in the world, all true sports fans have had their eyes literally glued on events on Falmer campus. Sussex University’s annual Fit to Get Committed Commit to Get Fit reached its final stages yesterday with the audience literally electrified by a thrilling Rounders competition. Team MPS didn’t win that event; although playing very well they were just a bit short of clichés, especially in the final third.

I wasn’t able to attend today’s lunchtime prize-giving event owing to a prior commitment. In fact I was on a course learning how to make legally fair disciplinary decisions. Fortunately this turned out to be an unnecessary precaution, as the MPS Commit to Get Fit team won all the awards!

Well done to Matt for winning Best Blog by an Individual and to Naomi who was presented with a Special Individual Achievement award for her dedication as Team Captain, her personal achievements and fundraising activities where she dressed up as a musketeer for the day, together with Matt, to raise money for the Rocking Horse Foundation. Together they managed to raise a whopping £210!

So once again the School of Mathematical and Physical Sciences sweeps the board. Literally.

 

Pass List Party

Posted in Biographical, Education with tags , , on June 13, 2014 by telescoper

Well, as I mentioned yesterday the pass lists for students in the School of Mathematical and Physical Sciences at the University of Sussex went up at noon. Students and staff started to gather a bit in advance and we also made a few preparations for the celebration ..

Pass list prep

When the results were wheeled out there was an immediate scrum accompanied by plentiful popping of Prosecco corks.

Pass list party

I’d just like to congratulate all our students on their success. The results were truly excellent this year. Enjoy the moment and be proud of their achievement. I suspect that many will have been enjoying the day out in the sunshine perhaps even with a small intake of alcoholic refreshment. I on the other hand have been at Senate all afternoon. But I’m not bitter…

The Busyness of Examination Time

Posted in Biographical, Education with tags , , , , , on June 12, 2014 by telescoper

Just time this evening for the briefest of brief posts. This is probably the busiest week of the year at the University of Sussex, and it’s not over yet. The main reason for this busyness is the business of examinations, assessment and degree classification.

This morning we had our meeting of the School Progression and Award Board for Years 3 and 4 at which, among other things, we sorted out the classification for honours of our graduating students. This involves distilling the marks gained over several years of assessments down to a final “Grand Mean”. It’s not a trivial process but I’m glad to say it went off very smoothly.

The pass lists have now gone to be officially signed off by the University administration. They will be posted tomorrow at noon, at which time we’ll have a celebratory drink or several ready for those getting their results.

One of my duties as Head of School is to chair this meeting, but I don’t take credit for the successful running of the meeting because all the hard work of preparation was done by our excellent office staff, especially Oonagh and Chrystelle.

That done there was time for a quick sandwich lunch before heading off to Stanmer House for a teaching “away afternoon” for the Department of Physics & Astronomy, at which we discussed ideas for improvements to the way we teach and assess students.

Stanmer

I’m actually in the group sitting under the parasol in the left foreground.

Stanmer House is set in beautiful parkland just a short walk from Sussex University. I took the more strenuous route over the hill, but am glad I did so because the view was so nice in the glorious sunshine and it made be realise I don’t make as much of the opportunity for walking around the campus as I should.

Tomorrow is going to be another busy day but, if you’ll excuse me, I’m now going to have a glass of chilled white wine and a bite to eat.

Out of Power

Posted in Biographical with tags , , on June 1, 2014 by telescoper

I had quite a few things to do on campus today before jetting off on a short trip tomorrow. I hoped to finish them in time for a decent blog post before heading home for tea and the Beelzebub crossword. Unfortunately when I got to the University just after 1pm I found the building in darkness. It turns out that the power went off about 10am. A little investigation revealed that all the buildings North-South Road (that’s the part of the Sussex University campus where all the science buildings are located) had a complete power outage due to a probably probably due to a fault in the high-voltage supply onto campus. Engineers had been called out as soon as the fault was reported but, not being qualified to work on such equipment themselves, power wasn’t restored until just after 4pm with the arrival of a specialist crew.

One thing worth saying about this is that the School of Mathematical and Physical Sciences does have an emergency response procedure for such eventualities and since as Head of School I’m officially a “responsible person” I had to make a judgement as to whether there was a serious threat to safety. If there had been, I would have had to execute the plan, contact all the relevant personnel, and order people out of the building. I decided that there wasn’t so just informed the students who were in the building what the situation was and that they could stay if they wanted. The emergency lighting was working and there was no immediate danger of anything nasty happening.

I went for a stroll around campus to see the extent of the outage. The only sign of life nearby was the sound from the emergency generators in the Shawcross building which kicked in to keep the main campus servers up and running. The PC room at the front of the building was deserted. Presumably the students who usually work there at weekends had found an alternative location, or were just outside enjoying the sunshine until the systems started up again, and any staff in attendance were presumably working on the backup systems in the bowels of the building.

No computers were working in our building either of course so some decided to work in the Library, which is on the other side of campus and wasn’t affected by the power cut. After checking out with the campus services what was going on I decided to stay until the fault was rectified just in case there were any problems. Some of our physicists had experiments running over the weekend and one or two came in to check that there was no serious harm done to their gear. There may be some faults to deal with tomorrow morning, but by then I’ll be elsewhere!

Such things as power cuts are inconvenient but they remind us how dependent we have become on electricity, especially for running computers. Fortunately this happened on a Sunday so there wasn’t much happening on campus, but a huge amount of our activities rely on digital devices of one form or another and it would have been much worse had it happened on a week day. The worst thing as far as I’m concerned, however, is that with no computer to work on I was deprived of displacement activities and was forced to start marking the scripts from Theoretical Physics examination…

The Cake Equation

Posted in The Universe and Stuff with tags , , , on May 31, 2014 by telescoper

Yesterday being the last Friday of the month of May it was time for another tea-and-cake event in the School of Mathematical and Physical Sciences. These provide an opportunity for staff to get together and chat while demolishing a specially-themed cake. The cakes themselves are organized by the inestimable Miss Lemon and I never know what the theme is before the goods arrive, so I have to ad lib a short introduction (for just a minute, without repetition, hesitation, deviation or repetition) before cutting the cake.

As you will observe, this time the (Lemon Drizzle) cake was decorated with the Dirac Equation (which I consider to be the most beautiful equation in physics)..

Examination Times

Posted in Biographical, Education with tags , , , , , on May 19, 2014 by telescoper

After a gloriously sunny weekend, it’s now a gloriously sunny Monday. There always seems to be good weather when students are revising for, or actually taking, their examinations. It’s Mother Nature’s special torture. The bus I was on this morning went past a large crowd of students waiting outside the Sports Hall in the bright sunshine for some examination or other.  The sight did remind me that I usually post something about examinations at this time of year, so here’s a lazy rehash of my previous offerings on the subject.

My feelings about examinations agree pretty much with those of  William Wordsworth, who studied at the same University as me, as expressed in this quotation from The Prelude:

Of College labours, of the Lecturer’s room
All studded round, as thick as chairs could stand,
With loyal students, faithful to their books,
Half-and-half idlers, hardy recusants,
And honest dunces–of important days,
Examinations, when the man was weighed
As in a balance! of excessive hopes,
Tremblings withal and commendable fears,
Small jealousies, and triumphs good or bad–
Let others that know more speak as they know.
Such glory was but little sought by me,
And little won.

It seems to me a great a pity that our system of education – both at School and University – places such a great emphasis on examination and assessment to the detriment of real learning. On previous occasions, before I moved to the University of Sussex, I’ve bemoaned the role that modularisation has played in this process, especially in my own discipline of physics.

Don’t get me wrong. I’m not opposed to modularisation in principle. I just think the way modules are used in many British universities fails to develop any understanding of the interconnection between different aspects of the subject. That’s an educational disaster because what is most exciting and compelling about physics is its essential unity. Splitting it into little boxes, taught on their own with no relationship to the other boxes, provides us with no scope to nurture the kind of lateral thinking that is key to the way physicists attempt to solve problems. The small size of many module makes the syllabus very “bitty” and fragmented. No sooner have you started to explore something at a proper level than the module is over. More advanced modules, following perhaps the following year, have to recap a large fraction of the earlier modules so there isn’t time to go as deep as one would like even over the whole curriculum.

In most UK universities (including Sussex), tudents take 120 “credits” in a year, split into two semesters. In many institutions, these are split into 10-credit modules with an examination at the end of each semester; there are two semesters per year. Laboratories, projects, and other continuously-assessed work do not involve a written examination, so the system means that a typical  student will have 5 written examination papers in January and another 5 in May. Each paper is usually of two hours’ duration.

Such an arrangement means a heavy ratio of assessment to education, one that has risen sharply over the last decades,  with the undeniable result that academic standards in physics have fallen across the sector. The system encourages students to think of modules as little bit-sized bits of education to be consumed and then forgotten. Instead of learning to rely on their brains to solve problems, students tend to approach learning by memorising chunks of their notes and regurgitating them in the exam. I find it very sad when students ask me what derivations they should memorize to prepare for examinations. A brain is so much more than a memory device. What we should be doing is giving students the confidence to think for themselves and use their intellect to its full potential rather than encouraging rote learning.

You can contrast this diet of examinations with the regime when I was an undergraduate. My entire degree result was based on six three-hour written examinations taken at the end of my final year, rather than something like 30 examinations taken over 3 years. Moreover, my finals were all in a three-day period. Morning and afternoon exams for three consecutive days is an ordeal I wouldn’t wish on anyone so I’m not saying the old days were better, but I do think we’ve gone far too far to the opposite extreme. The one good thing about the system I went through was that there was no possibility of passing examinations on memory alone. Since they were so close together there was no way of mugging up anything in between them. I only got through  by figuring things out in the exam room.

I think the system we have here at the University of Sussex is much better than I’ve experienced elsewhere. For a start the basic module size is 15 credits. This means that students are usually only doing four things in parallel, and they consequently have fewer examinations, especially since they also take laboratory classes and other modules which don’t have a set examination at the end. There’s also a sizeable continuously assessed component (30%) for most modules so it doesn’t all rest on one paper. Unusually compared with the rest of the University, Physics students don’t have many examinations in the January mid-year examination period either. Although there’s still in my view too much emphasis on assessment and too little on the joy of finding things out, it’s much less pronounced than elsewhere. Maybe that’s one of the reasons why the Department of Physics & Astronomy does so consistently well in the National Student Survey?

We also have modules called Skills in Physics which focus on developing the problem-solving skills I mentioned above; these are taught through a mixture of lectures and small-group tutorials. I don’t know what the students think of these sessions, but I always enjoy them because the problems set for each session are generally a bit wacky, some of them being very testing. In fact I’d say that I’m very impressed at the technical level of the modules in the Department of Physics & Astronomy generally. I’ve been teaching Green’s Functions, Conformal Transformations and the Calculus of Variations to second-year students this semester. Those topics weren’t on the syllabus at all in my previous institution!

Anyway, my Theoretical Physics paper is next week (on 28th May) so I’ll find out if the students managed to learn anything despite having such a lousy lecturer. Which reminds me, I must get the rest of their revision notes onto the Study Direct website…

Promoting Women in Physics at Sussex

Posted in Education, The Universe and Stuff with tags , , , , , on April 28, 2014 by telescoper

At the end of a very busy day of meetings I suddenly remembered that I forgot to pass on a nice bit of news about the Department of Physics & Astronomy at the University of Sussex.

It doesn’t seem very long ago at all that I announced the promotion of its first ever female Professor of Physics in the Department, Prof. Antonella de Santo. In fact it was in July last year. Well, just before the Easter break I was delighted at the promotion panel’s decision  to appoint the second female Professor in the Department. The successful candidate this time was Clauda Eberlein, who has been promoted to a Chair in Theoretical Physics with immediate effect.

I’ve already posted about how the proportion of female undergraduates studying physics as been stuck at around the 20% mark for a decade despite strenuous efforts to widen participation. A recent (2012) study by the Institute of Physics contains a wealth of statistical information about staff in Physics departments, which I encourage people to read if they’re interested in the overall issue with equality and diversity in physics. Here I’ll just pull out the figure (based on a 2010 survey) that out of a total of 650 Professors of Physics (and/or Astronomy) in the UK, just 5.5% were female. At that date about 20 physics departments had no female professors at all; that would have included Sussex, of course.

The first ever female Professor of Physics in the United Kingdom was Daphne Jackson, a nuclear physicist, who took up her Chair at the University of Surrey way back in 1971. It’s interesting to note that when Daphne Jackson studied physics as an undergraduate at Imperial College she was one of only two women among the 88 undergraduates in her year.

Congratulations to Claudia on her promotion, but the news doesn’t end there. Claudia will actually be taking over as Head of the Department of Physics & Astronomy in January 2015. She is currently Director of Teaching and Learning for the School of Mathematical and Physical Sciences and will take up her new role when the current Head of Physics & Astronomy, Philip Harris, stands down, having served his term in admirable fashion. Anyway, when Claudia takes up her post as Head of Department she will join an elite band of female physicists to have been appointed to such a role. Does anyone out there know how many other women have headed a Physics department?

 

 

 

 

Why Graduate Teaching Assistantships Should Be Scrapped

Posted in Education with tags , , , , , , on April 24, 2014 by telescoper

There’s an interesting piece in today’s Times Higher about the variability in pay and working conditions for Graduate Teaching Assistants across the UK Higher Education sector. For those of you not up with the lingo, Graduate Teaching Assistants (GTAs) are (usually) PhD students who fund their doctoral studies by doing some teaching for the department in which they are studying. As the piece makes clear, the use of GTAs varies widely between one university and another across the country and indeed between one department and another within the same university. The use of such positions is higher in arts and humanities departments than in science and engineering, because the latter general have more opportunity to fund scholarships for PhD students, either from one of the Research Councils or elsewhere. Such scholarships pay a stipend (tax-free) as well as the fee for studying as a PhD student.

When I arrived at the University of Sussex last year I found that the School of Mathematical and Physical Sciences operated a GTA scheme in parallel with Research Council bursaries. Students funded by a research council scholarship received a stipend paid at a national rate of about £13,600 per annum, but were able to top this up by undertaking a limited amount of teaching in the School (e.g. marking coursework, helping with workshops, or demonstrating in the teaching laboratories). Externally funded students did teaching on a voluntary basis. The GTAs on the other hand were required to undertake a fixed amount of teaching without remuneration in order to cover their fees.

I found this two-tier system unfair and divisive, with students funded as GTAs clearly treated as second-class citizens. One of the first major decisions I made as Head of School was to phase out the GTA scheme and replace it with bursaries on exactly the same terms as externally-funded ones with the same opportunity to top up the stipend with some teaching income. I announced this at a School meeting recently and it was met with broad approval, the only reservation being that it would be difficult if too few students opted to do extra teaching to cover the demand. I think that’s unlikely, actually, because although the stipend is not taxable so is equivalent to a somewhat higher amount in salary terms, Brighton is quite an expensive part of the country and most students would opt for a bit of extra dosh. Also, it is actually very good for a PhD student to have teaching experience on their CV when it comes to looking for a job.

Existing GTA schemes make it too easy for departments engage in exploitative behaviour, by dumping a huge amount of their teaching duties on underpaid and unqualified PhD students. It’s also unfair for the undergraduate students, nowadays paying enormously high fees, to be fobbed off onto PhD students instead of being taught by full-time, experienced and properly trained staff. Of course the system I’m advocating will be difficult to implement in departments that lack external funding for PhD students. Having to pay a full-stipend for each student will be more expensive and will consequently lead to a reduction in the number of PhD students that can be funded, but that’s not necessarily a bad thing. Indeed, the whole structure of undergraduate teaching will have to change in many departments. From what I’ve seen in the National Student Survey, that isn’t necessarily a bad thing either…

As I’ve argued a number of times on this blog, the current system drastically overproduces PhD students. The argument, a matter of simple arithmetic, is that on average in a steady state each potential PhD supervisor in the university system will, over their entire career, produce just one PhD student who will get a job in academia. In many fields the vast majority of PhDs have absolutely no chance of getting a permanent job in academia. Some know this, of course, and take their skills elsewhere when they’ve completed, which is absolutely fine. But I get the strong feeling that many bright students are lured into GTAs by the prospect that an illustrious career as an academic awaits them when really they’re just being hired as cheap labour. The result is a growing pool of disillusioned and disaffected people with PhDs who feel they’ve been duped by the system.

The British system of postgraduate research study is that it basically takes three years to do a degree. In the United States it usually takes much longer, so the employment of students as GTAs has less of an impact on their ability to complete their thesis on schedule. Although there are faults with the UK’s fast-track system, there is also much to recommend it. Not, however, if the student is encumbered with a heavy teaching load for the duration. The GTA scheme (which incidentally didn’t exist when I did my PhD nearly thirty years ago) is a damaging American import. In much of continental Europe there are far fewer PhD students and in many countries, especially in Scandinavia, PhD students are actually paid a decent wage. I think that’s the way we should go.

Research Hive on Open Access

Posted in Open Access, The Universe and Stuff with tags , , , , on March 21, 2014 by telescoper

Near the end of a week that has been both exciting and exhausting, I had the opportunity to take part in a seminar on Open Access publishing. I agreed to do this last year sometime, and only remembered that it was today because I got an email reminder a couple of days ago! Anyway it was nice to have an excuse to visit the iconic Library of the University of Sussex for this event.

Fortunately, as things turned out, I had plenty of topical material to draw on for inspiration and spent some time discussion the possibilities of community peer review with reference with what’s been happening with BICEP2. Here’s me in the middle of the talk on that very subject showing the Live Discussion Facebook page:

Hive

I shared the bill with Rupert Gatti from Open House Press which publishes mainly in the Arts and Humanities area; generally speaking these disciplines are a long way behind astrophysics in terms of their readiness for the age of Open Access but I think change across all academia is inevitable.

For those of you interested I realize that an update on the Open Journal For Astrophysics is long overdue. I’ve just been too busy with other things to devote much time to it. I do hope to have further news very soon…

NOvA and Neutrinos

Posted in The Universe and Stuff with tags , , , , on March 11, 2014 by telescoper

Yesterday’s Grauniad blog post by Jon Butterworth about neutrino physics reminded me that I forgot to post about an important milestone in the development of the NOvA Experiment which involves several members of the Department of Physics and Astronomy in the School of Mathematical and Physical Sciences here at the University of Sussex. Here’s the University of Sussex’s press release on the subject, which came out a couple of weeks ago.

The NOvA experiment consists of two enormous  particle detectors, one at the Fermi National Accelerator Laboratory “Fermilab” near Chicago and the other in Minnesota. The neutrinos are actually generated  at Fermilab; the particle beam is then aimed  at the detectors the, one near the source at Fermilab, and the other in Ash River, Minnesota, near the Canadian border. The particles, sent in their billions every couple of seconds, complete the 500-mile trip in less than three milliseconds.

The point is that the experiment has managed for the first time to actually detect neutrinos through the 500 miles of rock separating the two ends of the experiment. This is obviously just a first step, but it’s equally obviously a crucial one.

Colleagues from Sussex University are strongly involved in  calibrating and fine-tuning the detector, which produces light when particles pass through it. Dr Abbey Waldron and PhD student Luke Vinton have developed a calibration procedure that uses known properties of  muons to calibrate precise measurements of the neutrinos, which are less well understood.  The detector sees 200,000 particle interactions a second, produced by cosmic rays bombarding the atmosphere, and scientists can’t record every single one. Sussex’s Dr Matthew Tamsett has developed a trigger algorithm that searches for events that look like neutrinos among the billions of other particle interactions.

Neutrino physics is an interesting subject to someone like me, who isn’t really a particle physicist. My impression of the field is that was fairly moribund until 1998 when the first measurement of atmospheric neutrino oscillations was announced. All of a sudden there was evidence that neutrinos can’t all be massless (as many of us had long assumed, at least as far as lecturing was concerned).  Now the humble neutrino is the subject of intense experimental activity, not only in the USA and UK but all around the world in a way that would have been difficult to predict twenty years ago.

But then, as the physicist Niels Bohr famously observed, “Prediction is very difficult. Especially about the future.”
