I thought I’d post this now because (a) the title is topical and (b) because playing a piece by a black musical genius is the best way I can think of to refute David Starkey’s on Newsnight last night that there’s nothing more to “black culture” (whatever that means) than drugs and gang violence. This track, called Riot, is from the album Nefertiti, by the superb Miles Davis Quintet of the late 60s, which included Wayne Shorter, Herbie Hancock (who wrote the tune), Ron Carter on bass and Tony Williams on drums. It’s one of the most played albums on my iPod, but I very much doubt Dr Starkey has ever heard of it…

Nicholas Robinson; Burglary; 6 months: An appropriate sentence? (via MTPT)
Posted in Uncategorized with tags burglary, nicholas-robinson, riots, sentencing, uncategorized on August 13, 2011 by telescoperI hope we all agree that all the looting and violence was wrong, but 6 months in prison for stealing something worth £3.50….really?
I personally think these “rioters” (most of whom seem to be simply opportunistic thieves) would be better punished by being made to clear up the mess they’ve made…i.e. by community service orders.

DEUS
Posted in Cosmic Anomalies, The Universe and Stuff with tags Axis of Evil, Copenhagen, Dark Cosmology Centre, WMAP Cold Spot on August 12, 2011 by telescoperWell, I’m back home from Copenhagen after a very interesting and stimulating workshop called “DEUS” (subtitled “Current and Future Challenges of the Dark and Early Universes”). I just thought I’d post a brief message to thank the organizers for inviting me and for arranging such an interesting and varied programme, and especially for giving so many young researchers the chance to give talks (as well as some old farts like me).
Although I’d originally planned to talk about something else, I evenually decided to do a variation on the theme of cosmic anomalies, a topic I’ve blogged about at various times over the past couple of years. In a nutshell this was a quick overview of various features of the observed universe that seem to suggest departures from the standard “Lambda-CDM” (or LCDM, for short) cosmological model, including the famous WMAP Cold Spot, the Axis of Evil, and various other statistical hints of anomalous behaviour in present-day observations.
To add a bit of audience participation I gave those attending my talk the chance to vote on what they thought about these – I was genuinely interested to see what this particular audience felt about whether the standard model is threatened or not. I asked specifically about these in order to exclude other niggling worries people might have about LCDM from other astrophysical arguments, such as galaxy formation. Anyway, I thought it might be fun to repeat the poll here, so feel free to add your vote here:
As for the results of the vote during my presentation, I was somewhat surprised to see a roughly equal division between A and B, but there were even a few in C. I had assumed the vast majority would vote “A”….
Anyway, thanks again to the organizers of a fun meeting. That’s three trips to Copenhagen in as many months. I guess it will be a while before I go back again. 😦

Posted in Poetry with tags Lord Byron, Poetry, There is a pleasure in the pathless woods on August 12, 2011 by telescoperThere is a pleasure in the pathless woods,
There is a rapture on the lonely shore,
There is society, where none intrudes,
By the deep sea, and music in its roar:
I love not man the less, but Nature more,
From these our interviews, in which I steal
From all I may be, or have been before,
To mingle with the Universe, and feel
What I can ne’er express, yet cannot all conceal.
by George Gordon, Lord Byron (1788-1824)

Posted in Politics with tags Ed Milliband, Not the Nine O'Clock News, Politics, riots, soccer hooliganism on August 11, 2011 by telescoperLooking at the news feeds during my last evening in rainy Copenhagen, I see that the Leader of the Opposition, Ed Milliband, has weighed in with an armful of brand new platitudes he obviously acquired during the riots, including a dig at so-called “academic” studies into the causes of violent disorder.
I think this is a big mistake. A serious academic study would undoubtedly reveal a deep sociological connection between mob violence of the type recently experienced in England and the soccer hooliganism of the 70s and 80s. The pioneering research discussed in the following news clip offers a radical suggestion for solving the problem of youth violence.

Art in the Afternoon
Posted in Art, The Universe and Stuff with tags Alberto Giacometti, David Hockney, Henry Moore, Hven, Louisiana, Museum of Modern Art, Tycho Brahe on August 10, 2011 by telescoperJust a quick blogette to mention that yesterday the workshop participants here in Copenhagen went on an excursion to the Louisiana Museum of Modern Art, which is just north of Copenhagen.
This is an extremely interesting museum to visit at any time, not just for the temporary exhibitions which at present include the architecturally-themed Living and some wonderful drawings made by David Hockney using his iPad; the latter almost made me want to go out and buy one.
There’s also a fine permanent collection, including many wonderful sculptures by Alberto Giacometti :
and several by Henry Moore standing (or rather reclining) in the grounds:

What’s really great about Louisiana though is its relaxed informal atmosphere; kids are encouraged to play around (and sometimes in) the scupltures, there is lots of green space to relax in, and you are welcome even to swim in the sea, although I didn’t because I didn’t have my bathing costume with me. Many consider modern art and its galleries to be a bit pretentious, but that couldn’t be further than the truth for this place. I’ll also add that it was very busy indeed so is obviously extremely popular.
For those of you not so interested in Modern Art (which actually seemed to the case for many of my dining companions last night), there is a strong astronomical connection with this place because it offers a view of the Island of Hven on which Tycho Brahe established a famous observatory Uraniborg.

I’ve been to Louisiana many times but have never taken the short boat trip out to Hven, largely because there’s nothing much of the observatory left. Apparently the locals were squeezed mercilessly for taxes to pay for the running costs of Tycho’s observatory, with the result that by the time Brahe left in 1597 the residents of Hven were thoroughly fed up with him and tore the whole thing down.
The moral is clear of that little story is clear: astronomers need to keep the public on their side!
Now it’s time to start the workshop for today so I’d best be off…

Posted in Biographical, Finance, Politics with tags alienation, Copenhagen, Dark Cosmology Centre, London Riots, Marx on August 9, 2011 by telescoperI’m in Copenhagen, yet again, for the third time in as many months, this time for a workshop arranged by the Dark Cosmology Centre at the Niels Bohr Institute. It’s my talk this morning, in fact, so although I’m up early I haven’t got much time to post. I have to work on my talk to see if there’s a way I can make it all fit in 30 minutes!
Copenhagen is a pretty familiar place to me, but this has to be the most unsettling trip I’ve ever made here. I’m not talking about the long delay at Heathrow airport before we took off; I’ve come to expect that. The airport clearly can’t cope with the level of traffic it is supposed to handle during the summer months, so you have to reckon on at least an hour delay inbound and outbound. Sitting on the tarmac for an hour while being told over and over again that it will be “just a few minutes” really does bring out the grumpy old man in me. Still, at least I didn’t lose any luggage.
No, the reason this is such an unsettling trip is that back home in Blighty all hell seems to have broken lose, with riots in the streets of, first, London and now apparently Birmingham, Liverpool and Bristol. I was also on the march in 1990 that turned into the Poll Tax riot. I was appalled by the violence that day and got myself and my friends away from trouble as soon as it flared, but it has to be said that it did lead to a change in the law, something Parliament had failed to achieve.
Back to the present, I note that the Tesco at Bethnal Green, where I used to live, has apparently been looted. I hope all my friends in London are keeping themselves safe.
I don’t think there’s anything I can say about these riots that wouldn’t be ill-informed, unhelpful, or even downright stupid. I am however old enough to remember that such things have happened before, in deprived inner-city areas, including Liverpool and Bristol. The circumstances were similar too. Given the public spending cuts that have hit community programmes extremely hard, it doesn’t surprise me that some have decided to lash out, especially at the Police, whose criminal collusion with the media over phone-tapping and draconian tactics in dealing with lawful protests has turned many others against them .
I find it hard to separate these signs of social disintegration from the large-scale economic landscape. The huge level of debt accumulated by banks during the Credit Crunch of 2008 has now been absorbed by governments across the globe, who are attempting to deal with it by cutting public spending rather than raising taxes. Meanwhile the bankers have accepted their bailouts with glee, paying themselves bonuses by the bucketful and no doubt squirreling away the dosh in the Cayman Islands. If the state sanctions greed on that scale, is it surprising that people at the bottom of the heap decide to join in by looting the local supermarket?
The young have the right to feel particularly disillusioned. The current generation has lived beyond its means for too long and, realising it too late, is trying to pay for it by mortgaging the future. The opportunities our young people, especially those from less affluent backgrounds, can look forward to, in terms of education and jobs, will be much poorer than my generation.
I’m not usually one to endorse the view of the Daily Telegraph, but I think this piece hits the nail pretty much on the head. As Karl Marx would have said, it’s all about alienation, and I can tell you it’s not just the “underclass” that’s feeling it at the moment.
None of which is to condone the violence: you can be angry with the looters and the arsonists and those engaged in wanton destruction, but that doesn’t mean you shouldn’t try to understand why it’s happening.
But I’m very afraid that there’s going to be a lot more of this. The sovereign debt crisis is far from over. In many ways it has only just begun. There will be deeper cuts in public spending, greater inequality, greater social divisions and more upheavals like this. I think we’re in for a rough ride. I’m just glad I’m no longer young.

Posted in Poetry with tags Love and Tensor Algebra, Stanislaw Lem on August 8, 2011 by telescoperI’m off travelling for a few days to a conference, of which more anon (assuming I succeed in connecting to the interwebs while I’m away). It will do me some good to change location after the terrible week I’ve just had. Anyway, I thought I’d leave you with a whimsical poem while I’m travelling. It’s a bit silly, I know, but I like it. It’s called Love and Tensor Algebra and it was written by Stanislaw Lem.
Come, let us hasten to a higher plane
Where dyads tread the fairy fields of Venn,
Their indices bedecked from one to n
Commingled in an endless Markov chain!
Come, every frustum longs to be a cone
And every vector dreams of matrices.
Hark to the gentle gradient of the breeze:
It whispers of a more ergodic zone.
In Riemann, Hilbert or in Banach space
Let superscripts and subscripts go their ways.
Our asymptotes no longer out of phase,
We shall encounter, counting, face to face.
I’ll grant thee random access to my heart,
Thou’lt tell me all the constants of thy love;
And so we two shall all love’s lemmas prove,
And in our bound partition never part.
For what did Cauchy know, or Christoffel,
Or Fourier, or any Boole or Euler,
Wielding their compasses, their pens and rulers,
Of thy supernal sinusoidal spell?
Cancel me not – for what then shall remain?
Abscissas some mantissas, modules, modes,
A root or two, a torus and a node:
The inverse of my verse, a null domain.
Ellipse of bliss, converge, O lips divine!
the product of four scalars it defines!
Cyberiad draws nigh, and the skew mind
Cuts capers like a happy haversine.
I see the eigenvalue in thine eye,
I hear the tender tensor in thy sigh.
Bernoulli would have been content to die,
Had he but known such a^2 cos 2 phi!
