Neutrino Physics in a Small Universe

Posted in Biographical, The Universe and Stuff with tags , , , , , , , on April 23, 2013 by telescoper

I’ve only just got time for a quick lunchtime post before I head off to attend an afternoon of Mathematics presentations, but it’s a one of those nice bits of news that I like to mention on here from time to time.

It is my pleasure to pass on the wonderful news that one of my colleagues in the School of Mathematical and Physical Sciences here at the University of Sussex,  Dr Jeff Hartnell,. has been awarded  the High Energy Particle Physics prize of the Institute of Physics, which means that his name has now been added to the illustrious list of previous winners. The prize is awarded annually by the HEPP Group, a subject group in the Nuclear and Particle Physics Division of the IOP, to a researcher in the UK who has made an outstanding contribution to their field of study early in their career (within 12 years of being awarded their first degree).

There’s a very nice piece about this award here which reveals, amongst other things, that many moons ago at Nottingham I was Jeff’s undergraduate tutor! In fact Jeff also attended a third-year course on Theoretical Elementary Particle Physics I taught in those days. That he survived those experience and went on to be a world-leading physicist speaks volumes! Not only that, it’s also evidence that the world of physics is smaller than we sometimes suppose. I’ve crossed paths with a number of my new colleagues at various times in the past, but it’s particularly rewarding to see someone you taught as an undergraduate go on to a highly successful career as a scientist. Jeff was awarded a prestigious ERC grant this year too!

Jeff is currently in the USA helping to set up the largest-ever experiment in neutrinos to be built there, called NOvA. You can click on the preceding links for more technical details, and I also found this interesting video showing the NOvA detector being assembled. Particle physics experiments are never small, are they?

p.s. Why do they insist on writing “metric ton” instead of “tonne”?

Down with Fanatics!

If I had my way with violent men
I’d simmer them in oil,
I’d fill a pot with bitumen
And bring them to the boil.
I execrate the terrorist
And those who harbour him,
And if I weren’t a moralist
I’d tear them limb from limb.

Fanatics are an evil breed
Whom decent men should shun;
I’d like to flog them till they bleed,
Yes, every mother’s son,
I’d like to tie them to a board
And let them taste the cat,
While giving praise, oh thank the Lord,
That I am not like that.

For we should love the human kind,
As Jesus taught us to,
And those who don’t should be struck blind
And beaten black and blue;
I’d like to roast them in a grill
And listen to them shriek,
Then break them on the wheel until
They turned the other cheek.

Operation Wheeler

Posted in Uncategorized with tags , , on April 21, 2013 by telescoper

It has been a bit scary in Brighton today. The so-called March for England, took place this afternoon organized by the neo-Nazi English Defence League (no link to their website from me, you’ll observe). There was a massive police presence in town, at first concentrated on the seafront where the march was routed.

There were localized brawls between marchers and counter-demonstrators from the outset, and after the march ended various splinter groups from both dispersed around the city trying to cause disruption. The town has been at a standstill since about 2.30 as police sealed off isolated disturbances and protected bystanders. I was with a group of people near the Sea Life centre when half a dozen EDL thugs began hurling abuse and moving towards us in a very threatening way. The police intervened promptly and the agressors moved off. They may have subsequently joined a melee that then developed in the Old Steine and was attended by riot police but which did not last very long.

The number of marchers was about 150 (my estimate) with a similar number of counter-demonstrators; they were probably outnumbered by the Police, who had brought in reinforcements from elsewhere to assist with Operation Wheeler, their name for today’s huge activity. I saw vans from Hertfordshire, Norfolk and the City of London.

Anyway, with no serious injuries reported, I’d say Operation Wheeler was a success. I’ve heard that 13 arrests were made, for a variety of offences. I think the police did a very good job in extremely difficult circumstances.

Why have this march in Brighton? I don’t know, but judging by what I heard, the typical EDL marcher is not very fond of gay people and they probably came here because of Brighton’s large gay community and embrace of other forms of diversity. Racism, homophobia and other forms of prejudice seem often to be acquired as a package. To be honest, I think the EDL just came looking for trouble and didn’t really care that much where it was to be found.

Though the only violent acts I saw were carried out by EDL supporters there were extremists on the other side also spoiling for a fight. I think it would have been far more effective if the counter-protest had been totally peaceful. If thugs come looking for trouble, the worse thing to do is meet them at their level because that’s exactly what they want. The way to defeat people like the EDL is to behave better than they do which, based on today’s evidence, is by no means difficult..

The seafront remained closed for some time after the march had finished…

You can’t see very well in this image, but in the background a group of EDL supporters are being detained by the police.

These police horses are right next to “Legends”. There was a nice bit of banter going on between them and the largely gay clientele drinking out front.

Police vans from Norfolk and the City of London. I can’t be sure, but I think the seagull was local.

Counting for the REF

Posted in Open Access, Science Politics with tags , , , , , , on April 20, 2013 by telescoper

It’s a lovely day in Brighton and I’m once again on campus for an Admissions Event at Sussex University, this time for the Mathematics Department in the School of Mathematical and Physical Sciences.  After all the terrible weather we’ve had since I arrived in February, it’s a delight and a relief to see the campus at its best for today’s crowds. Anyway, now that I’ve finished my talk and the subsequent chats with prospective students and their guests I thought I’d do a quick blogette before heading back home and preparing for this evenings Physics & Astronomy Ball. It’s all go around here.

What I want to do first of all is to draw attention to a very nice blog post by a certain Professor Moriarty who, in case you did not realise it, dragged himself away from his hiding place beneath the Reichenbach Falls and started a new life as Professor of Physics at Nottingham University.  Phil Moriarty’s piece basically argues that the only way to really judge the quality of a scientific publication is not by looking at where it is published, but by peer review (i.e. by getting knowledgeable people to read it). This isn’t a controversial point of view, but it does run counter to the current mania for dubious bibliometric indicators, such as journal impact factors and citation counts.

The forthcoming Research Excellence Framework involves an assessment of the research that has been carried out in UK universities over the past five years or so, and a major part of the REF will be the assessment of up to four “outputs” submitted by research-active members of staff over the relevant period (from 2008 to 2013). reading Phil’s piece might persuade you to be happy that the assessment of the research outputs involved in the REF will be primarily based on peer review. If you are then I suggest you read on because, as I have blogged about before, although peer review is fine in principle, the way that it will be implemented as part of the REF has me deeply worried.

The first problem arises from the scale of the task facing members of the panel undertaking this assessment. Each research active member of staff is requested to submit four research publications (“outputs”) to the panel, and we are told that each of these will be read by at least two panel members. The panel comprises 20 members.

As a rough guess let’s assume that the UK has about 40 Physics departments, and the average number of research-active staff in each is probably about 40. That gives about 1600 individuals for the REF. Actually the number of category A staff submitted to the 2008 RAE was 1,685.57 FTE (Full-Time Equivalent), pretty  close to this figure. At 4 outputs per person that gives 6400 papers to be read. We’re told that each will be read by at least two members of the panel, so that gives an overall job size of 12800 paper-readings. There is some uncertainty in these figures because (a) there is plenty of evidence that departments are going to be more selective in who is entered than was the case in 2008 and (b) some departments have increased their staff numbers significantly since 2008. These two factors work in opposite directions so not knowing the size of either it seems sensible to go with the numbers from the previous round for the purposes of my argument.

There are 20 members of the panel so 6400 papers submitted means that, between 29th November 2013 (the deadline for submissions) and the announcement of the results in December 2014 each member of the panel will have to have read 640 research papers. That’s an average of about two a day…

It is therefore blindingly obvious that whatever the panel does do will not be a thorough peer review of each paper, equivalent to refereeing it for publication in a journal. The panel members simply won’t have the time to do what the REF administrators claim they will do. We will be lucky if they manage a quick skim of each paper before moving on. In other words, it’s a sham.

Now we are also told the panel will use their expert judgment to decide which outputs belong to the following categories:

  • 4*  World Leading
  • 3* Internationally Excellent
  • 2* Internationally Recognized
  • 1* Nationally Recognized
  • U   Unclassified

There is an expectation that the so-called QR  funding allocated as a result of the 2013 REF will be heavily weighted towards 4*, with perhaps a small allocation to 3* and probably nothing at all for lower grades. The word on the street is that the weighting for 4* will be 9 and that for 3* only 1. “Internationally recognized”  will be regarded as worthless in the view of HEFCE. Will the papers belonging to the category “Not really understood by the panel member” suffer the same fate?

The panel members will apparently know enough about every single one of the papers they are going to read in order to place them  into one of the above categories, especially the crucial ones “world-leading” or “internationally excellent”, both of which are obviously defined in a completely transparent and objective manner. Not. The steep increase in weighting between 3* and 4* means that this judgment could mean a drop of funding that could spell closure for a department.

We are told that after forming this judgement based on their expertise the panel members will “check” the citation information for the papers. This will be done using the SCOPUS service provided (no doubt at considerable cost) by   Elsevier, which by sheer coincidence also happens to be a purveyor of ridiculously overpriced academic journals.  No doubt Elsevier are  on a nice little earner peddling meaningless data for the HECFE bean-counters, but I have no confidence that they will add any value to the assessment process.

There have been high-profile statements to the effect that the REF will take no account of where the relevant “outputs”  are published, including a pronouncement by David Willetts. On the face of it, that would suggest that a paper published in the spirit of Open Access in a free archive would not be disadvantaged. However, I very much doubt that will be the case.

I think if you look at the volume of work facing the REF panel members it’s pretty clear that citation statistics will be much more important for the Physics panel than we’ve been led to believe. The panel simply won’t have the time or the breadth of understanding to do an in-depth assessment of every paper, so will inevitably in many cases be led by bibliometric information. The fact that SCOPUS doesn’t cover the arXiv means that citation information will be entirely missing from papers just published there.

The involvement of  a company like Elsevier in this system just demonstrates the extent to which the machinery of research assessment is driven by the academic publishing industry. The REF is now pretty much the only reason why we have to use traditional journals. It would be better for research, better for public accountability and better economically if we all published our research free of charge in open archives. It wouldn’t be good for academic publishing houses, however, so they’re naturally very keen to keep things just the way they are. The saddest thing is that we’re all so cowed by the system that we see no alternative but to participate in this scam.

Incidentally we were told before the 2008 Research Assessment Exercise that citation data would emphatically not be used;  we were also told afterwards that citation data had been used by the Physics panel. That’s just one of the reasons why I’m very sceptical about the veracity of some of the pronouncements coming out from the REF establishment. Who knows what they actually do behind closed doors?  All the documentation is shredded after the results are published. Who can trust such a system?

To put it bluntly, the apparatus of research assessment has done what most bureaucracies eventually do; it has become  entirely self-serving. It is imposing increasingly  ridiculous administrative burdens on researchers, inventing increasingly  arbitrary assessment criteria and wasting increasing amounts of money on red tape which should actually be going to fund research.

And that’s all just about “outputs”. I haven’t even started on “impact”….

Remembering David Axon

Posted in The Universe and Stuff with tags , , , on April 19, 2013 by telescoper

Over the past couple of days there has been a special Memorial Event to remember David Axon, my predecessor as Head of  the School of Mathematics and Physical Sciences at the University of Sussex, who passed away suddenly on 5th April 2012. The memorial event has consisted of a two-day specialist discussion meeting of the Royal Astronomical Society about David’s primary research interest – Massive Black Holes in Galaxies – here on the Sussex campus and will end this afternoon with a Memorial Service in the Meeting House Chapel, which will include music and poetry.

Professor David John Axon (1951-2012)

Although I knew David Axon through his published work I didn’t know him very well at all personally. In fact we only met a couple of times. The first of those occasions was when we’d both applied for a certain job. He was interviewed before me and came into the room in which I was waiting when he had finished. You would never expect such a situation to be comfortable, but it turned out to be so because David was very friendly and direct. Those are precisely the qualities that I’ve heard described over the last few days by many people who knew him far better than I did. People say these qualities reflect his Northern heritage. I won’t argue with that, except to point out that he was born in Doncaster, i.e. in the Midlands….

As David’s successor here at Sussex all I can do is say that he clearly left the School of Mathematical and Physical Sciences in excellent shape, which is testament to the energy and ability he brought to the job that I now hold.  He set a very high standard. Equally clearly, David Axon is sorely missed, by staff and students alike, not just in MPS but throughout the University.

Such occasions are inevitably a bit sad, but this occasion is, as it should be, very much the celebration of a life and I’m sure David will live on in the memories of those who knew him closely, as it will for one person who met him only briefly. Remembering David Axon is something many people will do for a very long time.

Technical Support

Posted in Education with tags , , , on April 18, 2013 by telescoper

We’re approaching the end of term here at the University of Sussex and there are lots of things that need to get finished before then, so it’s a very busy day. Just time for a quick post to pass on some great news and a comment.

One of my colleagues when I worked in the School of Physics & Astronomy at Cardiff University, Steven Baker, has won an award for being the best STEM Technician in the category of Physical Sciences in the whole country! This is an new award set up by the Higher Education Academy, so Steven is the inaugural winner of it.  Although I suspect he won’t enjoy being the centre of attenti0n very much I’m very pleased that he won this award. Among many other things he was central in setting up the  gear that enabled current 4th-year Cardiff MPhys students to have a much wider selection of modules, by accessing lectures from Swansea University by video link.

I’m also delighted that this award has been set up generally because I feel very strongly that the contribution made by support staff in university departments.  No Physics department can run with out a dedicated crew of technicians who apply their expertise in both teaching and research laboratories, but there are many more people – clerical staff, computer officers, etc – without whom many of our activities would grind to a halt. None of these support staff gets the recognition they deserve; they are often poorly paid and lack an appropriate career structure that reflects the importance of the work they do.

So Steven’s award is an occasion not just for him to celebrate, but also to remind us academics that we couldn’t do what we do without people like him doing all the difficult stuff!

The Bravery of Being out of Range

Posted in Poetry, Politics with tags , , , , , on April 16, 2013 by telescoper

I’ve been planning for some time to post the lyrics of the song The Bravery of being out of Range by Roger Waters (ex Pink Floyd) as a response to the  ongoing covert war being waged by the United States, which has claimed thousands of innocent lives in Pakistan and elsewhere. The terrible events at the Boston Marathon yesterday reminded me of this intention.  Violence always  begets violence, but the circle becomes all the more vicious when the agressor doesn’t have to display a jot of personal courage. And that goes just as much to those who planted the bombs in Boston as those who aim the drones in Pakistan. Regardless of whether the Boston bombs had anything to do with American policy, when violence is made easy there’s bound to be more of it.

You have a natural tendency
To squeeze off a shot
You’re good fun at parties
You wear the right masks
You’re old but you still
Like a laugh in the locker room
You can’t abide change
And you’re home on the range
You opened the suitcase
Behind the old workings
To show off the magnum
You deafened the canyon
A comfort a friend
Only upstaged in the end
By the Uzi machine gun
Does the recoil remind you
Remind you of sex
Old man what the hell you gonna kill next
Old timer, who you gonna kill next

I looked over Jordan and what did I see
Saw a U.S. Marine in a pile of debris
I swam in your pools
And lay under your palm trees
I looked in the eyes of the Indian
Who lay on the Federal Building steps
And through the range finder over the hill
I saw the front line boys popping their pills
Sick of the mess they find on their desert stage
And the bravery of being out of range
Yeah the question is vexed
Old man what the hell you gonna kill next
Old timer who you gonna kill next

Hey bartender, over here
Two more shots
And two more beers
Sir, turn up the TV sound
The war has started on the ground
Just love those laser guided bombs
They’re really great for righting wrongs
You hit the target, win the game
From bars 3,000 miles away
3,000 miles away
We play the game
With the bravery of being out of range
We zap and maim
With the bravery of being out of range
We strafe the train
With the bravery of being out of range
We gain terrain
With the bravery of being out of range
We play the game
With the bravery of being out of range

R.I.P. Sir Colin Davis

Posted in Music with tags , , , on April 15, 2013 by telescoper

Yesterday (Sunday 14th April), the conductor Sir Colin Davis died at the age of 85. This is very sad news indeed. I won’t event attempt to write a comprehensive obituary piece here. Many others have already done this much more knowledgeably than I could ever do. You can also get an idea of the affection in which he was held by looking at the condolence page at the website of the London Symphony Orchestra, the orchestra with which he was associated for over fifty years.

What I will do is pay a small tribute in my own way by posting this sprightly and engaging version of For unto us a child is born from Handel’s Messiah which shows him in action, conducting the London Symphony Orchestra (at the Barbican in London) with a very characteristic combination of authority and obvious enjoyment.

Farewell, Sir Colin Davis. You will be greatly missed.

Britten’s Children

Posted in Music with tags , , , , on April 14, 2013 by telescoper

I’ve recently been working my way through a pile of books I bought over the years but haven’t yet got around to reading. The latest is Britten’s Children by John Bridcut which I think I bought shortly after it was published in 2006 but have only just finished. I don’t know why it took me so long to read this book, but with this year being the centenary of the composer Benjamin Britten’s birth I felt I shouldn’t make any more subconscious excuses.

This book is quite a scholarly work (completely with musicological references, etc)  that describes Britten’s life in music alongside the story of the numerous friendships with adolescent  boys which were a constant theme in his life. I won’t go through a list of these because the wikipedia page about this book contains such an inventory, but it is worth noting that most of these friendships involved good-looking boys around 13/14 and that there certainly was at least an aesthetic element to Britten’s interest; the man himself certainly didn’t attempt to disguise this physical aspect of the attraction. However, it is quite clear from the often passionate letters exchanged between himself and the various boys concerned that these relationships were not exploitative, but based on a strong mutual affection.

In fact only one of the boys Britten befriended, Harry Morris, ever claimed that Britten had made sexual advances to him. Britten often invited his young friends to come with him on holiday, which they did with full parental permission. That in itself seems strange in the light of the reaction the mere suspicion of paedophilia is likely to  provoke nowadays. One would have thought it was much worse in Britten’s day when homosexual behaviour between adults was illegal, never mind between adults and young boys. As it happens, though, Britten was never even investigated for any form of indecent behaviour. His friendship with Harry Morris ended after the abrupt termination of a trip to Cornwall during which, Morris later claimed, Britten made some sort of approach to him. However, there are quite a few inconsistencies in Morris’ telling of the story, so there is considerable doubt over exactly what happened there. Anyway, I’ll resist the temptation to discuss whether the composer may have made overtures to this particular young man, and move on.

Reading the many excerpts from letters and transcriptions of interviews held with a number of the protagonists in later life, I think that Britten’s motivations were fundamentally benign. He just liked to be surrounded by beautiful youths, an attitude likely to be demonized today but actually not so much in the past. Many of Shakespeare’s Sonnets, for example, are addressed to a “fair youth” from an older man. They talk of male beauty,  passionate mutual attraction in such a way that it is easy to assume that they describe  sexual desire. They may do that, of course, but I’m not convinced that’s necessarily the case; there are many kinds of love, including those that do not need to be physically consummated.

This brings me to the origin of the phrase “the love that dare not speak its name” which most take to refer to homosexual desire. In fact it’s not as simple as that. The phrase was coined by Oscar Wilde in the following excerpt taken from the transcript of his criminal trial for gross indecency in 1895:

‘The love that dare not speak its name’, in this century, is such a great affection of an elder for a younger man as there was between David and Johnathan. Such as Plato made the very basis of his philosophy, and such as you may find in the sonnets of Michelangelo or Shakespeare. It is, in this century, misunderstood. So much misunderstood that it may be described as ‘the love that dare not speak its name’, and on account of it I am placed where I am now. It is beautiful. It is fine. It is the noblest form of affection. There is nothing unnatural about it. It is intellectual. And it repeatedly exists between an elder and a younger man when the elder has intellect and the younger man has all the joy, hope and glamour of life before him. That it should be so, the world does not understand. The world mocks at it and sometimes puts someone in the pillory for it.

Anyway, as you can imagine if you haven’t read the book, this is very delicate ground, but John Bridcut is both tactful and direct in the way he presents it. Britten was a complicated man who could be very difficult, so this is no hagiography, but neither does it pander to prurience. He must have done a good job because even the reviewer in the Daily Telegraph wrote:

Nowadays a known homosexual who sought out the company and affection of small boys would probably end up on a police register or behind bars. In treating Britten’s fondness for the young of his own sex as something more than lipsmacking paedophilia, this book does him a service both as a man and an artist.

In many ways the most interesting things to emerge from the book for me (as a non-expert on Britten) are things that are quite separate from the central theme. I hadn’t realized, for example, that Britten was a fine sportsman: he was an accomplished cricketer, swimmer and tennis player and was in fact Victor Ludorum at his school. That contrasts with the somewhat bookish persona I’ve always associated with him based on photographs. I was also fascinated to read that he composed music sitting at a desk. Only when he’d finished a piece (or at least a substantial fraction thereof) would he play it through on the piano. That may be common practice among composers, actually. I don’t know.

The other strand that’s woven into this story is Britten’s relationship with his life partner, Peter Pears. I hadn’t realized that Pears and Britten were actually pretty close friends for a couple of years before their relationship became a physical one. Pears apparently wasn’t always comfortable with Britten’s younger house guests – and their relationship had its ups and downs for other reasons too – but they stayed together until Britten died in 1976. I think the bond between them was all the stronger because it incorporated a mutual love of music. Earlier in his life, Britten was on the periphery of a Bohemian clique that included Christopher Isherwood and W.H. Auden, but both he and Pears decided that wasn’t for them; they settled down to a life of  fogeyish conventionality, a marriage in all but name. When Britten passed away, Her Majesty the Queen sent Peter Pears a telegram expressing her condolences. I look forward to the, hopefully near, future when all same-sex relationships are afforded the same level of respect.
