Posted in Biographical with tags birth on July 21, 2014 by telescoperBack in Cardiff for the weekend I was looking for some documents and stumbled across this, my National Health Service Baby Weight Card (vintage 1963). I’m told that I even lost a bit of weight between my birth and the first entry on the card:
Aside from my considerable mass two further facts about my birth are worth mentioning. One is that I emerged in the incorrect polarization state, with shoulders East-West instead of North-South; the result of this was that my left collarbone was broken during the delivery. I imagine this wasn’t exactly a comfortable experience for my mother either! I subsequently broke the same collarbone falling off a wall when I was a toddler and it never healed properly, hence I can’t rotate my left arm. If I try to do the front crawl when swimming I go around in circles! The other noteworthy fact of my birth was that when I was finally extricated I was found to be completely covered in hair, like a monkey…

Posted in Poetry with tags Derek Mahon, Poem, Poetry, The Thunder Shower on July 19, 2014 by telescoperA blink of lightning, then
a rumor, a grumble of white rain
growing in volume, rustling over the ground,
drenching the gravel in a wash of sound.
Drops tap like timpani or shine
like quavers on a line.
It rings on exposed tin,
a suite for water, wind and bin,
plinky Poulenc or strongly groaning Brahms’
rain-strings, a whole string section that describes
the very shapes of thought in warm
self-referential vibes
and spreading ripples. Soon
the whispering roar is a recital.
Jostling rain-crowds, clamorous and vital,
struggle in runnels through the afternoon.
The rhythm becomes a regular beat;
steam rises, body heat—
and now there’s city noise,
bits of recorded pop and rock,
the drums, the strident electronic shock,
a vast polyphony, the dense refrain
of wailing siren, truck and train
and incoherent cries.
All human life is there
in the unconfined, continuous crash
whose slow, diffused implosions gather up
car radios and alarms, the honk and beep,
and tiny voices in a crèche
piercing the muggy air.
Squalor and decadence,
the rackety global-franchise rush,
oil wars and water wars, the diatonic
crescendo of a cascading world economy
are audible in the hectic thrash
of this luxurious cadence.
The voice of Baal explodes,
raging and rumbling round the clouds,
frantic to crush the self-sufficient spaces
and re-impose his failed hegemony
in Canaan before moving on
to other simpler places.
At length the twining chords
run thin, a watery sun shines out,
the deluge slowly ceases, the guttural chant
subsides; a thrush sings, and discordant thirds
diminish like an exhausted concert
on the subdominant.
The angry downpour swarms
growling to far-flung fields and farms.
The drains are still alive with trickling water,
a few last drops drip from a broken gutter;
but the storm that created so much fuss
has lost interest in us.

Posted in Beards, Biographical, The Universe and Stuff with tags Estonia, IAU Symposium 308, Tallinn on July 16, 2014 by telescoperRegular readers of this blog (Sid and Doris Bonkers) will recall that I recently attended IAU Symposium No. 308 in Tallinn, Estonia. To prove that I didn’t make it all up, here is the official conference photograph.
You can see me three rows back on the right-hand-side of the picture; you can click on the image to make it largely should you wish. Behind me and to my left as I look at the camera you will see the esteemed cosmologist Carlos Frenk wearing an unusual facial expression.
I wonder if anyone might like to suggest an explanation for Prof. Frenk’s behaviour by way of a suitable caption for the photograph?

CAMPAIGNERS WELCOME FIRST TORY CABINET MINISTER WITH A BEARD SINCE 1905
The Beard Liberation Front, the informal network of beard wearers, has welcomed David Cameron’s decision to appoint Preseli Pembrokeshire MP Stephen Crabb as Welsh Secretary in the new Cabinet.
Crabb becomes the first Tory Cabinet Minister with a beard since the 4th Earl of Onslow stepped down as President of the Board of Agriculture in March 1905*
The campaigners say that the Tory Party has had a reputation for pogonophobia, reinforced when John Selwyn Gummer was reputedly told by Mrs Thatcher to shave his beard off if he wanted a Cabinet seat. In more recent years there have been a few hirsute Tory MPs such as John Randall who has just signalled his intention to step down as MP for Uxbridge

End of Term Report: David Willetts
Posted in Education, Politics, Science Politics with tags David Willetts, Department of Business Innovation and Skills, Higher Education, Reshuffle, Science is Vital on July 15, 2014 by telescoperNews broke yesterday that the Minister responsible for Universities and Science within the Department of Business, Innovation and Skills, David Willetts, had stepped down from his role and would be leaving Parliament at the next election.
Willetts’ departure isn’t particularly surprising in itself, but its announcement came along with a host of other sackings and resignations in a pre-Election cabinet reshuffle that was much wider in its scope than most expected. It seems to me that Prime Minster David Cameron has decided to play to the gallery again. After almost four years in which his Cabinet has been dominated by white males, most of them nondescript timeserving political hacks without beards, he has culled some of them at random to try to pretend that he does after all care about equality and diversity. Actually, I don’t think David Cameron cares for very much at all apart from his own political future and this is just a cynical attempt to win back some votes before the next Polling Day, presumably in May 2015. Rumour has it that one of the new Cabinet ministers may even have facial hair. Such progress.
David Willetts was planning to step down at the next General Election anyway so his departure now was pretty much inevitable. I never agreed with his politics, but have to admit that he was a Minister who at least understood some things about Higher Education. In particular he knew the value of science and secured a flat cash settlement for the science budget at a time when other Whitehall budgets were suffering drastic cuts. He was by no means all bad. He even had the good taste – so I’m told – to read this blog from time to time….
The campaigning organization Science is Vital has expressed its sadness at his departure:
We’re sorry to see David Willetts moved from the Science Minister role. He listened, in person, to our arguments for increasing public funding for science, and we appreciated the support he showed for science within the government.
We look forward to renewed dialogue with his successor, in order to continue to press the case that science is vital for the UK.
Now that he has gone, my main worry is that the commitments he gave to ring-fence the science budget will go with him. I don’t know anything about his replacement, Greg Clark, though I hope he follows his predecessor at least in this regard.
Other aspects of Willetts’ tenure of the Higher Education office are much less positive. He has provided over an ideologically-driven rush to force the University sector into an era of chaos and instability, driven by a rigged quasi-market propelled by an unsustainable system of tuition fees funded by student loans, a large fraction of which will never be repaid.
Another of Willetts’ notable failures relates to Open Access. Although apparently grasping the argument and make all the right noises about breaking the stranglehold exerted on academia by outmoded forms of publication, he sadly allowed the agenda to be hijacked by vested interests in the academic publishing lobby. Fortunately, there’s still a very strong chance that academics can take this particular issue into their own hands instead of relying on the politicians who time and time again prove themselves to be in the pockets of big business.
My biggest fear for Higher Education at the moment is that the new Minister will turn out to be far worse and that if the Conservatives win the next election (which is far from unlikely), Science is Vital will have to return to Whitehall to protest against the inevitable cuts. If that happens, it may well be that David Willetts is remembered not as the man who saved British science, but the man who gave it a stay of execution.
Follow @telescoperThis Is Our Music – A tribute to Charlie Haden
Posted in Jazz with tags Charlie Haden, Don Cherry, Ed Blackwell, Jazz, Ornette Coleman, This is Our Music on July 14, 2014 by telescoperI was saddened at the weekend to hear of the death, on Friday 11th July, at the age of 76, of the great jazz bassist, Charlie Haden. I always associate Charlie Haden with a series of great records he made with Ornett Coleman and Don Cherry during the late 50s and early 60s, including The Shape of Jazz to Come and Change of the Century, both of which I’ve blogged about already. I thought I’d pay a little tribute to Charlie Haden by writing about another of these masterpieces, a disc called This Is Our Music. As with the other two, this is also available in full on Youtube so you can listen to it here:
When he first arrived on the jazz scene the licence Coleman allowed himself in his improvisations drew criticism bordering on abuse from several prominent musicians. This a view echoed, for example, by the great Charles Mingus in quote I got from another blog about Ornette Coleman
Now aside from the fact that I doubt he can even play a C scale in whole notes—tied whole notes, a couple of bars apiece—in tune, the fact remains that his notes and lines are so fresh. So when [the jazz dj] Symphony Sid played his record, it made everything else he was playing, even my own record that he played, sound terrible.
Although he clearly admired his originality, Mingus may have been right about the very young Ornette Coleman’s technical ability; but I don’t think any unbiased listener could argue that he lacked mastery of his instrument by the time this record was made, in 1960. His skill in sustaining notes (always difficult on alto sax, which he plays throughout this album) is especially evident on this album in the standard Embraceable You whilst the precision of his articulation at any temp makes it quite clear that he really had little to learn in any aspect of control of his instrument. The slurs and distortions that are so much a part of his style are beautifully managed, and combine with his daring tonal approach to give the impression of great freedom that he strove to convey in his music.
It used to be question whether the liberties in which Coleman indulged were not so as extreme as to preclude overall unity, yet for all his virtuosity in rhythmic and melodic invention, he displays a genuine continuity of line in everything he does on this record. On Blues Connation, for example, his solo evolves with impeccable logic, each phrase growing almost inexorably out of the one before, whilst the general melodic shape bears continuous affinity to the theme. Moreover, his music boasts an intensity of feeling that no charlatan could ever hope to achieve. As I hear it, the dominant emotion in his playing at fast tempo is not love, as some have claimed, so much as fear, although this mood is often relieved by flashes of lyrical sadness. In the slower pieces, such as Beauty is a Rare Thing and Embraceable You, and the medium-paced Humpty Dumpty, the latter sentiment comes through even more strongly.
Don Cherry was an ideal partner, for his work is cast in a similar mould, but at this stage in his own development he did tend to stand in Coleman’s shadow. Drummer Ed Blackwell is very good throughout, but Charlie Haden is nothing short of brilliant, which is why I chose this as a tribute piece for him.
The bassist Haden not only displays all the classic jazz virtues expected of him, but also possesses an amazing sense of anticipation that enables him to work hand in glove with the two hornmen. Blackwell is neither a loud nor an aggressive drummer, but he evinces genuine drive and the interweaving mobility he and Haden achieve together is truly remarkable in its own right as well as fitting well with the richness of the leader’s own work.
Had I the time, I could write a lot more about this album in particular and about Charlie Haden in general, but all I can do his suggest that you listen to the LP for yourself. Coleman was still refining his concept of how his Quartet should function, so it’s a little rough around the edges in places, and in any case I know many devout jazz fans who find this kind of music challenging. It is worth it, though. Charlie Haden was only 22 when This Is Our Music was recorded. He went on to many great things during his subsequent career. Sadly that spark has now gone out, but he will live on in our hearts through his music.
Rest in Peace, Charlie Haden, Jazz legend (1937-2014).
