Saturday Night Function

Posted in Jazz with tags , , on January 16, 2016 by telescoper

Well, it’s Saturday Night so I thought I’d post a bit of classic Jazz from the late twenties. This is from the superb Duke Ellington band, vintage 1929, which was resident at the Cotton Club in Harlem, New York City. I haven’t seen a personnel listing for this but a couple of the soloists are easy to identify: Barney Bigard on clarinet and Joe “Tricky Sam” Nanton on trombone. The tune Saturday Night Function has become a traditional jazz standard but not many bands can get close to that unique Ellington sound, especially the growling trumpets. Enjoy!

How bad is Stormtrooper aim exactly?

Posted in Uncategorized on January 15, 2016 by telescoper

Here’s a tongue-in-cheek analysis of the inaccuracy of stormtroopers’ use of firearms in the Star Wars movies.

This is just one manifestation of a general phenomenon – bad guys are always terrible shots! At least in movies…

For some unknown reason, I’ve been thinking a lot about Star Wars recently. Going forward, I’ll assume you’ll be familiar with the events and characters of at least the first six films. If not, what have you been doing? Living in a recent, recent time in a galaxy that’s very close to here? Broadly speaking, this post inevitably contains minor spoilers for Episodes II−VI of the Star Wars films. If you haven’t seen them, inexplicably want to find out about Stormtrooper aim and don’t mind knowing some plot details, then feel free to read on.

There are some characteristics of characters or groups of characters within the Star Wars register that are widely held to be fact. This may be despite them not being explicitly stated within the films. Red lightsabers are for the…

Should the ‘Roast beef of Old England’ be restored as the English anthem?

Should the ‘Roast Beef of Old England’ be restored as English anthem

beef

Chesterfield MP Toby Perkins may have a point in bringing  a bill to the Commons to replace God Save the Queen at sporting events where the England team plays with a specifically English anthem.

The national anthem, God Save the Queen or King, first became common in the 1790s when ‘Church and King’ mobs backed by sailors were keen to oppose radicals who supported the French Revolution.

The traditional English anthem had been the Roast Beef of Old England, and the playing of the new national anthem did not always go down well. A riot took place in Sheffield in 1812 when naval officers insisted it was played at a theatrical performance.

Mr Perkins, not to be confused with Harry Perkins in Chris Mullins a Very British Coup novel, is a supporter of hard right group Progress in…

Truly, Madly, Deeply – R.I.P. Alan Rickman

Posted in Film with tags , , on January 14, 2016 by telescoper

Well, I can’t say that I’m very impressed with 2016 so far. Now the wonderful actor Alan Rickman has been taken from us. The first time I saw him act was on the small screen, in a bit part in Smiley’s People. Anyone remember who he played? It says a lot about his talent that he could make such a small role so memorable. However the first feature film I saw him in was Truly, Madly, Deeply which co-starred the marvellous Juliet Stevenson. I cried more than I’d like to admit.

Anyway, by way of a tribute here he is singing, appropriately enough, The Sun Ain’t Gonna Shine Anymore.

Rest in peace, Alan Rickman (1946-2016).

Harassment and Confidentiality

Posted in Harassment Bullying etc with tags , , on January 13, 2016 by telescoper

News of yet another sexual harassment scandal in Astronomy has broken, this time at Caltech. The individual concerned was not named by Caltech but has subsequently been identified as Christian Ott (whom I don’t know at all), who was investigated following complaints by two female PhD students. The complaints were upheld and Ott has been suspended.

This case would be difficult enough to comment on even without the complex backstory, some of which is in the public domain: two of the three protagonists appear in this article which dates from 2014. Clearly a lot has happened since then and it would be intrusive and unhelpful for me to speculate publicly about things know I nothing about.

What I will say, as clearly as I possibly can, that it is that due process has been followed and that there is no question the right decision was reached. My only surprise is that Dr Ott was not summarily dismissed.

In the interests of full disclosure I should make it clear that I do know one of the complainants in a professional capacity, Sarah Gossan, who was an undergraduate Astrophysics student at Cardiff while I was there and who started a PhD at Caltech in 2012.

Also for the record I should state that one of my duties as a Head of School here at the University of Sussex is to investigate and deal  with allegations of harassment or other misconduct by staff. I obviously can’t comment on individual cases I have dealt with, but will say that it is probably my least favourite job but someone has do it.

If such a complaint is upheld it can lead to summary dismissal (for very serious misconduct) or, at very least, a formal written warning. It’s worth also stating that the standard applied is that of a Civil rather than Criminal Court, i.e. the decision is based on the “balance of the evidence” rather than “beyond reasonable doubt”.

Concerning the Caltech/Ott case, according to this source:

The university investigation, which concluded in September, found that Ott violated the school’s harassment policies with both women. Ott, a 38-year-old rising star who had been granted tenure the year before, was placed on nine months of unpaid leave. During that time he is barred from campus, his communication with most of his postdoctoral fellows will be monitored, and, with the exception of a single graduate student, he is not allowed to have contact with any other students. Before returning, he must undergo what a school official calls “rehabilitative” training.

The first thing to say is that I find it very hard to believe that Ott will ever be able to return to his worksplace after the revelations of his behaviour even if he does attend “rehabilitative training”.  I very much doubt that the faculty or students would want him back. It surprises me that Caltech could even imagine that this is a realistic possibility.

Another feature worthy of comment is that Caltech itself did not name the perpetrator, although his name very rapidly appeared in the public domain. Disciplinary procedures of this type are also treated confidentially in all UK universities with which I am familiar (including the University of Sussex). I think there are good reasons for this, primarily to protect individuals from false or malicious allegations, but also to protect the complainant(s) from unwelcome publicity or other unwanted attention. However, it has to be said that this often also ends up protecting the culprit too. If  a person ends up getting the sack as as  result of sexual harassment then news will almost certainly leak out about why Dr Bloggs has left suddenly. However, if it leads to a warning then this outcome is generally not disclosed. In such a situation, Dr Bloggs could move to another institution and carry on where he left off.

They have been suggestions in the USA, discussed in this article, that legislation could be intoduced to force institutions to disclose information about harassment cases when an individual moves from one to another. I think this is an idea well worth thinking about, but I am not sure how workable it is in practice.

Failure to act strongly when such behaviour is proven just sends out the message that the institution doesn’t take sexual harassment seriously. In my view, confidentiality is needed during an investigation – to protect both sides and indeed the person doing the investigation – but if the conclusion is that misconduct has taken place, it should  be ackowledged publicly. Justice has to be seen to be done. Sexual assault, of course, is another matter entirely – that should go straight to the police to deal with.

I’ve talked about protocols and procedures, but these can only ever apply a sticking-plaster solution to a problem which is extremely deeply rooted in the culture of many science departments and research teams across the world. These tend to be very hierarchical, with power and influence concentrated in the hands of relatively few, usually male, individuals. A complaint about harassment generally has to go up through the management structure and therefore risks being blocked at a number of stages for a number of reasons. This sort of structure reinforces the idea that students and postdocs are at the bottom of the heap and discourages them from even attempting to pursue a case against someone at the top.

The unhealthy power structures I’ve discussed will not be easy to dismantle entirely, but there are simple things that can be done to make a start. “Flatter”, more democratic, structures not only mitigate this problem but are also probably more efficient by, for example, eliminating the single-point failures that plague hierarchical organisational arrangements.

We are very far indeed from eliminating harassment or the conditions that allow it to continue but although cases like this are painful, I think they at least demonstrate that we are beginning to acknowledge that there’s a problem.

 

On the Theory of Gravitational Wave Rumour Sources

Posted in Astrohype, The Universe and Stuff, Uncategorized with tags , , on January 12, 2016 by telescoper

There has been a great deal of excitement almost nowhere in the astrophysics community since it was announced recently that rumours of the detection of gravitational waves had yet again begun to circulate, so I thought I would add here a brief discussion of the theoretical background to these phenomena.

The standard theoretical model of such rumours is that they are  produced from time to time during the lifetime of a supermassive science project after periods of relative quiescence. It is thought that they are associated with a perceived lack of publicity which might threaten funding and lead to financial collapse of the project. This stimulates a temporary emission of hype produced by vigorous gossip-mongering which acts to inflate the external profile of the project, resisting external pressures and restoring equilibrium. This general phenomenon is not restricted to gravitational wave detection, but also occurs across many other branches of Big Science, especially cosmology and particle physics.

However, observations of the latest outburst suggest support for a rival theory, in which rumours are produced not by the project itself but by some other body or bodies in orbit around it or even perhaps entirely independent of it. Although there is evidence in favour of this theory, it is relatively new and many questions remain to be answered. In particular it is not known what the effect of rumours produced in this way might be on the long-term evolution of the project or on the source itself.

Lawrence Krauss is 61.

 

 

Dover Beach

The sea is calm tonight.
The tide is full, the moon lies fair
Upon the straits; on the French coast the light
Gleams and is gone; the cliffs of England stand,
Glimmering and vast, out in the tranquil bay.
Come to the window, sweet is the night-air!
Only, from the long line of spray
Where the sea meets the moon-blanched land,
Listen! you hear the grating roar
Of pebbles which the waves draw back, and fling,
At their return, up the high strand,
Begin, and cease, and then again begin,
With tremulous cadence slow, and bring
The eternal note of sadness in.

Sophocles long ago
Heard it on the Ægean, and it brought
Into his mind the turbid ebb and flow
Of human misery; we
Find also in the sound a thought,
Hearing it by this distant northern sea.

The Sea of Faith
Was once, too, at the full, and round earth’s shore
Lay like the folds of a bright girdle furled.
But now I only hear
Its melancholy, long, withdrawing roar,
Retreating, to the breath
Of the night-wind, down the vast edges drear
And naked shingles of the world.

Ah, love, let us be true
To one another! for the world, which seems
To lie before us like a land of dreams,
So various, so beautiful, so new,
Hath really neither joy, nor love, nor light,
Nor certitude, nor peace, nor help for pain;
And we are here as on a darkling plain
Swept with confused alarms of struggle and flight,
Where ignorant armies clash by night.

by Matthew Arnold (1822-1888)

The Renaissance of Sussex Physics

Posted in Education, The Universe and Stuff with tags , , on January 10, 2016 by telescoper

I’m grateful to Darren Baskill for compiling this plot which shows the number of graduates in Physics (including Astrophysics) from the Department of Physics & Astronomy at the University of Sussex since 2004.

Physics

The last two columns are projections, of course, but we can be rather confident about the numbers. The increase over the last few years is predominantly a result of having  more students enter our Physics programmes, but there has also been a significant increase in progression  rates (as a consequence of excellent teaching), which is why we think the predicted numbers of graduates in 2016 and 2017 are likely to be accurate.

One reason for the recent growth was that in 2008 – a particularly low year on the above graph – the Higher Education Funding Council for England (HEFCE) recognized that Physics departments in the South East were struggling to recruit sufficient numbers of students to be financially viable. This led to the formation of SEPNet, a five-year programme which resulted in an injection of cash to promote physics across the South East of England via a range of activities, including a vigorous outreach programme. This almost immediately began to increase the number of applications to do Physics at Sussex (and indeed across the SEPNet consortium), with the result that 3-4 years later the number of graduates started to climb. SEPNet-2, which started in 2013, has developed this initiative still further, with new initiatives in collaborative graduate education.

(For the record note that I took over as Head of School at the beginning of 2013. I will make no further comment…)

This increase in student numbers has generated more income for the Department, all of which is invested back into teaching, research and other activities (including more outreach!) to create a broader curriculum, more choice for students, and more teaching staff;  the number of staff in Physics & Astronomy has increased from 23 to 40 since 2013, for example.

The income generated by this expansion has allowed us to broaden our research base too. This seems an appropriate time to mention that a new research group in Materials Physics has just been established within the Department. Professor Alan Dalton from the University of Surrey will be joining the Department next month as Professor of Materials Physics, and several further appointments will follow to establish a new research activity in his area of interest.

Alan’s research interests focus on understanding the fundamental structure-property relationships in materials containing one- and two- dimensional structures such as carbon nanotubes, graphene and other layered nanomaterials. Alan is  particularly interested in developing viable applications for nano-structured organic composites (mechanical, electrical and thermal). He is also interested in the directed-assembly and self-assembly of nanostructures into functional macrostructures and more recently interfacing biological materials with synthetic inorganic and organic materials and associated applications.

I’m delighted by this development, which will not only create an entirely new research activity but also add significantly to the range of options we can offer students, as well as new opportunities for undergraduate projects and placements. It also has enormous potential to build links with other Departments, especially Chemistry (which is part of the School of Life Sciences).

To end with, I thought I would also comment on another chart that Darren produced:

FemalePhysics

Apart from showing the very high levels of achievement of our students, this provides quantitative evidence of something I had suspected for some time. Although the proportion of female Physics students overall has hovered around 23% with little change since 2004, the propotion of female students getting first class degrees is significantly higher than for male students.

So there you are. Women are better at Physics than men. Discuss.

 

Peace Piece

Posted in Jazz with tags , , on January 9, 2016 by telescoper

By way of an interlude in this busy period as term gets back underway I thought I’d post this beautiful track by the great jazz pianist Bill Evans. I remember reading somewhere that Bill Evans recorded this right at the end of a session, in 1958. It was unrehearsed, entirely improvised and done in one take. It’s based on a simple two-chord progression that subsequently appeared in Flamenco Sketches, one of the tracks on the classic Miles Davis album Kind of Blue. To my ears, Peace Piece is more redolent of the composition style of Erik Satie than any other jazz musician I can think of. Although it starts out very simply it becomes more complex and fragmented as it develops, and makes effective use of dissonance in creating tension to contrast with the rather meditative atmosphere established at the beginning. Anyway, this is one of my all-time favourite tracks by one of my all-time favourite jazz musicians so I hope you don’t mind me sharing it on here.
