Newcastle Joins the Resurgence of UK Physics

Posted in Education, Science Politics, The Universe and Stuff with tags , , , on August 17, 2014 by telescoper

I’ve posted a couple of times about how Physics seems to undergoing a considerable resurgence in popularity at undergraduate level across the United Kingdom, with e.g. Lincoln University setting up a new programme. Now there’s further evidence in that Newcastle University has now decided to re-open its Physics course for 2015 entry.

The University of Newcastle had an undergraduate course in Physics until 2004 when it decided to close it down, apparently owing to lack of demand. They did carry on doing some physics research (in nanoscience, biophysics, optics and astronomy) but not within a standalone physics department. The mid-2000s were tough for UK physics,  and many departments were on the brink at that time. Reading, for example, closed its Physics department in 2006; there is talk that they might be starting again too.

The background to the Newcastle decision is that admissions to physics departments across the country are growing at a healthy rate, a fact that could not have been imagined just ten years ago. Times were tough here at Sussex until relatively recently, but now we’re expanding on the back of increased student numbers and research successes. Indeed having just been through a very busy clearing and confirmation period at Sussex University, it is notable that its the science Schools that have generally done best.  Sussex has traditionally been viewed as basically a Liberal Arts College with some science departments; over 70% of the students here at present are not studying science subjects. With Mathematics this year overtaking English as the most popular A-level choice, this may well change the complexion of Sussex University relatively rapidly.

I’ve always felt that it’s a scandal that there are only around 40 UK “universities” with physics departments Call me old-fashioned, but I think a university without a physics department is not a university at all; it’s particularly strange that a Russell Group university such as Newcastle should not offer a physics degree. I believe in the value of physics for its own sake as well as for the numerous wider benefits it offers society in terms of new technologies and skills. Although the opening of a new physics department will create more competition for the rest of us, I think it’s a very good thing for the subject and for the Higher Education sector general.

That said, it won’t be an easy task to restart an undergraduate physics programme in Newcastle, especially if it is intended to have as large an intake as most successful existing departments (i.e. well over 100 each year). Students will be applying in late 2014 or early 2015 for entry in September 2015. The problem is that the new course won’t figure in any of the league tables on which most potential students based their choice of university. They won’t have an NSS score either. Also their courses  will probably need some time before it can be accredited by the Institute of Physics (as most UK physics courses are).

There’s a lot of ground to make up, and my guess is that it will take some years to built up a significant intake.The University bosses will therefore have to be patient and be prepared to invest heavily in this initiative until it can break even. The decision a decade ago to cut physics doesn’t exactly inspire confidence that they will be prepared to do this, but times have changed and so have the people at the helm so maybe that’s an unfair comment.

There are also difficulties on the research side (which is also vital for a proper undergraduate teaching programme), there are also difficulties. Grant funding is already spread very thin, and there is little sign of any improvement for the foreseeable future  in the “flat cash” situation we’re currently in. There’s also the stifling effect of theResearch Excellence Framework I’ve blogged about before. I don’t know whether Newcastle University intends to expand its staff numbers in Physics or just to rearrange existing staff into a new department, but if they do the former they will have to succeed against well-established competitors in an increasingly tight funding regime. A great deal of thought will have to go into deciding which areas of research to develop, especially as their main regional competitor, Durham University, is very strong in physics.

On the other hand, there are some positives, not least of which is that Newcastle is and has always been a very popular city for students (being of course the finest city in the whole world). These days funding follows students, so that could be a very powerful card if played wisely.

Anyway, these are all problems for other people to deal with. What I really wanted to do was to wish this new venture well and to congratulate Newcastle on rejoining the ranks of proper universities (i.e. ones with physics departments). Any others thinking of joining the club?

Sussex and the World Premier League of Physics

Posted in Education, The Universe and Stuff with tags , , , , , on August 16, 2014 by telescoper

In the office again busy finishing off a few things before flying off for another conference (of which more anon).

Anyway, I thought I’d take a short break for a cup of tea and a go on the blog.

Today is the first day of the new Premiership season and , coincidentally, last week saw some good news about the Department of Physics and Astronomy at the University of Sussex in a different kind of league table.

The latest (2014) Academic Rankings of World Universities (often called the “Shanghai Rankings”) are out so, as I suspect many of my colleagues also did, I drilled down to look at the rankings of Physics departments.

Not surprisingly the top six (Berkeley, Princeton, MIT, Harvard, Caltech, & Stanford) are all based in the USA. The top British university is, also not surprisingly, Cambridge in 9th place. That’s the only UK university in the top ten for Physics. The other leading UK physics departments are: Manchester (13th), Imperial (15th), Edinburgh (20th), Durham (28th), Oxford (39th) and UCL (47th). I don’t think there will be any surprise that these all made it into the top 50 departments worldwide.

Just outside the top 50 in joint 51st place in the world is the Department of Physics & Astronomy at the University of Sussex. For a relatively small department in a relatively small university this is a truly outstanding result. It puts the Department  clear in 8th place in the UK, ahead of Birmingham, Bristol, Leicester, Queen Mary, Nottingham, Southampton,  St Andrews, Lancaster, Glasgow, Sheffield and Warwick, all of whom made the top 200 in the world.

Incidentally, two of the other departments tied in 51st place are at Nagoya University in Japan (where I visited in January) and Copenhagen University in Denmark (where I’m going next week).

Although I have deep reservations about the usefulness of league tables, I’m not at all averse to using them as an excuse for a celebration and to help raise the profile of Physics and Astronomy at Sussex generally.  I’d therefore like to take the opportunity to offer hearty congratulations to the wonderful staff of the Department of Physics & Astronomy on their achievement. 

With the recent investments we’ve had and further plans for growth I hope over the next few years we can move even further up the rankings. Unless of course the methodology changes or we’re subect to a “random” (ie downward) fluctuation…

 

 

 

Fiery Fred

Posted in Cricket with tags , , on August 15, 2014 by telescoper

Since there’s a Test Match going on right now at the Oval and I’ve got a few minutes before my next task, I thought I’d just do a brief post to mark the anniversary of a very special cricketing moment. On this day in 1964, also at the Oval, Sir Fred Trueman became the first bowler to take 300 wickets in test matches. In his test career overall he took 307 wickets at an astonishingly low average of 21.57. He twice bowled spells in Test matches in which he took five wickets without conceding a run.

Here’s a short video to remind us all of what a superb action Fiery Fred Trueman had:

p.s. Fred Trueman was born in Yorkshire which, as you all know, is part of the Midlands.

Do-It-Yourself Supernova Explosion

Posted in Education, The Universe and Stuff with tags , , , , on August 15, 2014 by telescoper

Visitors to the office of the Head of the School of Mathematical and Physical Sciences at the University of Sussex often remark upon the presence of these two objects and inquire as to their purpose:

Supernova

Since I don’t play golf and am a bit long in the tooth to be a fan of Peppa Pig, most assume that it must be for some strange astrophysical reason. I tried asking on Twitter what people think I use them for, and the most common answer was to demonstrate the relative size of the Earth and Moon. As Roy Walker would have said, “That’s a good answer, but it’s wrong”.

In fact I use the objects concerned to demonstrate what goes on when a star goes supernova.

The point is that a supernova explosion begins with gravitational collapse of the progenitor star, so why does that manifest itself as an explosion? The point is that the outer layers are blown off while the core collapses into a compact object such as a neutron star or, perhaps, a black hole.

The way to demonstrate this is first to balance the golf ball (representing the outer layers) on top of the beach ball; the air hole in the latter is a useful place to do this. You then lift the conjoined objects to a reasonable height and drop them onto the table or bench provided for such a purpose in a lecture theatre. The objects fall together under gravity until the beach ball hits the surface. You will find that the beach ball (representing the core) stops still while the golf ball (representing the outer shells) shoots upwards as most of the kinetic energy of the system is transferred to it during the bounce.

I think this is quite an effective demonstration, but I’d encourage inexperienced lecturers to note that there is a Health and Safety Issue, so it is necessary to carry out a risk assessment before attempting it. When I first did this during a lecture many years ago, I used a ball bearing rather than a golf ball and a fully-inflated and much larger beach ball instead of the more manageable (and slightly deflated) Peppa Pig one I now use. I told the students in the audience to watch carefully what happened and then dropped them as described above…

What happened in that case was that the ball bearing rocketed up so fast that it reached the ceiling and smashed into the lights above the lecturer’s bench, whereupon there was a very loud bang and I was showered with broken glass and other debris. I have to say that got the loudest round of applause I’ve ever had while lecturing, but it wasn’t exactly the effect I’d been hoping for.

But the real reason for posting today is to wish a very happy 65th birthday to supernova expert extraordinaire and occasional reader of this blog, Robert Kirshner of Harvard University, who has celebrating along with a number of my astro-chums at a conference in Australia.

Many happy returns, Bob!

An American doctor experiences an NHS emergency room

Interesting perspective on our wonderful National Health Service…

You know it’s going to be one of those days when one of the first tweets on vacation inquires about the closest hospital.

IMG_8896Victor, one of my 11-year-olds, had something in his eye courtesy of a big gust of wind outside of Westminster Abby. He was complaining enough to let me flip his eyelid and irrigate his eye on the square in front of Big Ben. (I’m sure several people thought I was torturing him).  Despite an extensive search and rinse mission no object or relief was to be found. I fretted about going to the hospital. It wasn’t the prospect of navigating a slightly foreign ER, but simply the prospect of the wait. While I am a staunch supporter of the British NHS in the back of my mind I envisioned a paralyzingly full emergency room and an agonizing 18 hour wait only to find he had nothing in his…

Mathematics at Sussex: the videos!

Posted in Education on August 13, 2014 by telescoper

I recently posted a couple of videos illustrating some aspects of our undergraduate teaching in the Department of Physics & Astronomy here at the University of Sussex. Since I’m Head of the School of Mathematical and Physical Sciences, which encompasses Mathematics and Statistics as well as Physics & Astronomy, I thought I’d redress the balance with a couple of similar clips featuring mathematicians to give an idea of what students in the Department of Mathematics get up to.

First up is George Simpson, who graduated from Sussex this year with a (4-year) MMath and who is going to start a PhD here at the end of the summer:

And this is Hayley Wragg, a current MMath student, who is talking about her work as a Junior Research Associate in Mathematics:

Incidentally there is a vibrant and active Mathematics Society at Sussex, the University of Sussex Mathematics Society (SUMS). I’m not sure what the acronym is for Brighton University Mathematics Society…

O Captain! My Captain!

Posted in Film, Poetry with tags , , on August 12, 2014 by telescoper

O Captain! my Captain! our fearful trip is done,
The ship has weather’d every rack, the prize we sought is won,
The port is near, the bells I hear, the people all exulting,
While follow eyes the steady keel, the vessel grim and daring;
But O heart! heart! heart!
O the bleeding drops of red,
Where on the deck my Captain lies,
Fallen cold and dead.

O Captain! my Captain! rise up and hear the bells;
Rise up—for you the flag is flung—for you the bugle trills,
For you bouquets and ribbon’d wreaths—for you the shores a-crowding,
For you they call, the swaying mass, their eager faces turning;
Here Captain! dear father!
This arm beneath your head!
It is some dream that on the deck,
You’ve fallen cold and dead.

My Captain does not answer, his lips are pale and still,
My father does not feel my arm, he has no pulse nor will,
The ship is anchor’d safe and sound, its voyage closed and done,
From fearful trip the victor ship comes in with object won;
Exult O shores, and ring O bells!
But I with mournful tread,
Walk the deck my Captain lies,
Fallen cold and dead.

Genie, You’re Free..

Posted in Film with tags , , , on August 12, 2014 by telescoper

It’s been a hectic day so far but I couldn’t resist taking a little time out to post a little tribute to the enormous talent that was Robin Williams, who died last night having apparently taken his own life. Robin Williams was a unique comic talent, best displayed during his legendary stand-up routines, but also demonstrated to great effect on film, especially in Good Morning Vietnam and as the voice of the Genie in Disney’s Aladdin. These movies allowed him to express his remarkable spontaneous ability to connect ideas, characters and voices in a freewheeling improvised scenarios of breathtaking inventiveness; in both the films I mentioned his work was largely unscripted. In Good Morning Vietnam the cutaways to other actors while he did his bit in the radio studio clearly don’t show them acting, just cracking up as he cut loose his extraordinarily fertile imagination; and all the animators on Aladdin had to do to make a great film was to fill in images to match his free-flowing monologues, with celebrity impersonations and other funny voices thrown in for good measure.

Much has already been written about the sad circumstances of his death, and how he seems to have lost his long battle against depression. That a light that could shine so brightly has been lost to the darkness should be a cause of deep sadness, but no-one can really understand another person’s pain and it would be quite wrong to judge him selfish or weak because of the manner of his death. Instead, I shall remember him by the joy he gave – he was one of the comic actors who could reduce me to hysterics – and hope that in some way his loss might lead in some way to greater understanding of depression and other mental health problems.

The most moving tribute of many I’ve seen today on Twitter was from the The Academy of Motion Picture Arts and Sciences. The Genie in Aladdin yearned to be free, and now he is. RIP Robin Williams.

Supermoon Surgery

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

I have a busy day today (including my Annual Appraisal) to kick off a very busy week dominated by the release of this years A-level results and consequent admissions business, so I’ll just post a quickie though one which is at least fairly topical.

Last night (10th August) I took a (not very good) picture of the Moon with my phone:

 

supermoon

This is a so-called “supermoon“, a not particularly rare phenomenon which takes place when there is a Full Moon that coincides with the Moon being at the point of its orbit which is closest to the Earth, i.e. its perigee. A much better name is “Perigee Full Moon”, but that somehow doesn’t seem to have caught on in the popular media. The Moon orbits the Earth in an ellipse rather than a circle and at its closest approach it is about 14% closer than at its furthest (apogee). It therefore looks about 14% bigger and about 30% brighter during a Perigee Full Moon than during an Apogee Full Moon.

The Moon was certainly looking very bright when I took the picture last night, at least compared to a few minutes later when it disappeared behind a supercloud.

The Moon’s proximity to Earth during this Full Moon does have a noticeable effect on terrestrial tides, but not a particularly strong one; certainly not enough to trigger the end of the world. Actually, the tides have an amplitude just a few inches higher than average during a Perigee Full Moon. In any case roughly one in 14 Full Moons is a supermoon so it’s actually quite a common event, and as far as I’m aware the world didn’t come to an end during the last one or the one before that or the one before that or…

Anyway, all this supermoon malarkey reminded me of something that happened about 15 years ago,  just after I had moved to Nottingham to take up the position of Professor of Astrophysics at the University of Nottingham. I was sitting in my office, working – blogs hadn’t been invented then – when the phone rang and the voice at the other end said May I speak to Professor Coles please? When I replied that I was he, the caller went on to explain that he was a surgeon who worked at Queen’s Medical Centre, a hospital located right next to the University of Nottingham, with teaching staff working for the University.

It turned out that news of the setting up of the new Astronomy group there had made it into the University newsletter which my caller had seen. He asked if I had a few moments to answer a question about astrophysics which had been bothering him for some time and which he had just been discussing with some of his colleagues.  I said yes, and he asked: Does the Moon rotate?

I paused a bit, thinking how best to explain, and he went on to clarify his point, which was that if the Moon always has the same face towards the Earth does that mean it’s not rotating?

Understanding his question, I went on to explain that, yes, the Moon does rotate and that the reason it always shows the same face to the Earth (more-or-less, ignoring libration) is that the period of its rotation is the same as the Moon’s orbital period around the Earth. I also explained how to demonstrate this with two coffee mugs, moving one in a circle around the other and rotating the outer one so as to keep the handle pointing towards the central mug. Moreover, I explained the physics of this phenomenon, which is called tidal locking, and pointed out other examples in astrophysics.

After this spiel the caller said that was all very interesting but he had to go  now. Assuming I had bored him, as I fear I tend to do rather a lot, I apologized for going on about it for too long. He said no he wasn’t at all bored by the detail I had put in, he found it all absolutely fascinating. The reason for him needing to go was that he had to go back to tell the answer to the colleagues he had been discussing it with  just before phoning me.  They were all  in the operating theatre,  standing around a patient lying on the operating table, waiting  for him to return and complete the operation he had left in order to make the call…
