The Cool Web

Posted in Poetry with tags , , on August 9, 2012 by telescoper

Children are dumb to say how hot the day is,
How hot the scent is of the summer rose,
How dreadful the black wastes of evening sky,
How dreadful the tall soldiers drumming by,

But we have speech, to chill the angry day,
And speech, to dull the roses’s cruel scent,
We spell away the overhanging night,
We spell away the soldiers and the fright.

There’s a cool web of language winds us in,
Retreat from too much joy or too much fear:
We grow sea-green at last and coldly die
In brininess and volubility.

But if we let our tongues lose self-possession,
Throwing off language and its watery clasp
Before our death, instead of when death comes,
Facing the wide glare of the children’s day,
Facing the rose, the dark sky and the drums,
We shall go mad, no doubt, and die that way.

by Robert Graves (1895-1985)

A blog by any other name..

Posted in The Universe and Stuff with tags , , , on August 8, 2012 by telescoper

While I’m online I thought I’d pass on the following gripe.

\begin{gripe}

Some months ago I saw a message going around on Twitter that the Guardian was looking for new science bloggers to cover a wide range of disciplines for its website. After thinking hard about it, I decided to submit an application basically so I could find out more about what was involved and see if I really wanted to do it. Anyway, I’ve already written a commissioned piece for the Guardian website, so I thought it was an idea worth pursuing.

My idea wasn’t to scrap In the Dark or move it all to the Guardian, but to post less frequent and more sciencey pieces there and keep this as a personal ego-trip blog. The advantage of that being that they pay, whereas this blog doesn’t make me any dosh at all, and also presumably generates significantly wider exposure. As well as making a pitch for the content of the proposed blog, I had to think of a new title if In the Dark was to carry on, so I came up with Across the Universe, which seemed to me to emphasize nicely the cosmological slant of the pieces I would be likely to write. It’s not a new coinage, of course. It’s based on a Beatles song I have posted about previously.

So I filed the application and waited. Then I was contacted by Alok Jha, who looks after the Science blog network at the Grauniad, who initially made encouraging noises, explained that there would be minimal editorial control and  I would keep copyright of anything I wrote for them, etc. Most of my questions having been answered I awaited further developments. Then Alok Jha contacted me again and explained that the editorial team wanted me to jump through several extra hoops if I wanted to take the idea forward. I sensed cold feet. For a number of reasons, the timing of these new phases of the process were also very inconvenient, so, after mulling it over, I contacted Alok Jha and politely withdrew my application.

I’ve no regrets about that decision, and thought no more about it, until last week when the Guardian started to roll out its new blogging team. I was delighted to see neuroscientist, comedian, and fellow Cardiff University chappie Dean Burnett among the bloggers. Their new blogger for matters astronomical is Stuart Clark, a well-known and respected science writer who I’m sure will cover a wide range of interesting topics (as he has already started to do).

What I’m peeved about, however, is that Stuart’s blog title is Across the Universe, exactly what I had suggested in my proposal! Coincidence? I asked Stuart via Twitter and he told me that the name was suggested to him by none other than Alok Jha.

Of course the title isn’t copyrighted by me, and wasn’t even original, but it was my suggestion and I do think it’s very poor form to have appropriated what was on my proposal without asking or giving acknowledgement. I’ve no complaints about Stuart Clark, of course. He didn’t know what had happened, and I wish him well with his new blog – which I shall certainly be reading. But I’m not at all chuffed about the way this was handled by the Guardian.

In the interests of full disclosure, I should point out Alok Jha recently contacted me to apologize and say that he had “forgotten” that Across the Universe was the title I gave on my proposal.

\end{gripe}

Anyway, the upshot of all this is that I’ll be keeping In the Dark going pretty much as it is for the foreseeable future.

Health willing.

Top Tips for Academic Job Interviews..

Posted in Uncategorized on August 8, 2012 by telescoper

Not ready yet to resume full-time blogging, but have enough internet access to reassure everyone that I am indeed still alive, and able at least to reblog this nice article by Bruce Bassett, giving advice to anyone preparing for an interview for an academic position….

Bruce Bassett's avatarCosmology at AIMS

We have recently gone through an extensive senior job search for a joint position and the questions we asked the candidates were fairly generic. But I remember my own early job interviews and how badly prepared I was for them, so I thought it might be of interest to list the questions we asked the candidates and the kind of responses panels are typically looking for. At a certain level these questions are obvious as soon as you put yourself in the shoes of the interview panel, and that would be my single biggest piece of advice. Imagine that you are on an interview panel looking for a colleague. What would you be looking for?

Forbes recently crunched recruiter questions down to three core issues:  “Can you do the job? Will you love the job? And can we tolerate working with you?” In the academic context, where permanent positions…

Interlude

Posted in Uncategorized on August 3, 2012 by telescoper

Owing to foreseen circumstances I’m going to be taking a break from blogging for a while. Normal services will be resumed as soon as possible but, for the time being, there will now follow a short intermission.

 

The Epoch of Galaxy Formation, Durham 1988.

Posted in Biographical, The Universe and Stuff with tags , , , on August 2, 2012 by telescoper

The previous old conference photograph I posted seemed to be quite popular, so I thought I’d try an even older vintage. This was also taken at Durham, but at a meeting entitled The Epoch of Galaxy Formation, which took place between July 18th and 22nd 1988. Appropriately enough, this one is in glorious monochrome. Spot any familiar faces?

The Low-down on the LHC Boson

Posted in Open Access, The Universe and Stuff with tags , , , , , , on August 2, 2012 by telescoper

Although it’s a little late I thought I’d just put up a brief post to draw your attention to the news that a couple of technical papers have appeared on the arXiv giving updated details of the recent discovery at the Large Hadron of a new scalar particle that could be the Higgs boson. I don’t think it’s yet absolutely proven that this is what the new particle is, which is why I’ve called it the “LHC boson” in the title.

The ATLAS paper reports the detection of a Higgs-like particle with a 5.9 sigma confidence level, up from the 5.0 sigma reported on July 4. Here’s the abstract:

A search for the Standard Model Higgs boson in proton-proton collisions with the ATLAS detector at the LHC is presented. The datasets used correspond to integrated luminosities of approximately 4.8 fb^-1 collected at sqrt(s) = 7 TeV in 2011 and 5.8 fb^-1 at sqrt(s) = 8 TeV in 2012. Individual searches in the channels H->ZZ^(*)->llll, H->gamma gamma and H->WW->e nu mu nu in the 8 TeV data are combined with previously published results of searches for H->ZZ^(*), WW^(*), bbbar and tau^+tau^- in the 7 TeV data and results from improved analyses of the H->ZZ^(*)->llll and H->gamma gamma channels in the 7 TeV data. Clear evidence for the production of a neutral boson with a measured mass of 126.0 +/- 0.4(stat) +/- 0.4(sys) GeV is presented. This observation, which has a significance of 5.9 standard deviations, corresponding to a background fluctuation probability of 1.7×10^-9, is compatible with the production and decay of the Standard Model Higgs boson.

The paper from CMS reinforces the discovery of a Higgs-like particle with a mass of 125 GeV at a 5-sigma level of confidence:

Results are presented from searches for the standard model Higgs boson in proton-proton collisions at sqrt(s)=7 and 8 TeV in the CMS experiment at the LHC, using data samples corresponding to integrated luminosities of up to 5.1 inverse femtobarns at 7 TeV and 5.3 inverse femtobarns at 8 TeV. The search is performed in five decay modes: gamma gamma, ZZ, WW, tau tau, and b b-bar. An excess of events is observed above the expected background, a local significance of 5.0 standard deviations, at a mass near 125 GeV, signalling the production of a new particle. The expected significance for a standard model Higgs boson of that mass is 5.8 standard deviations. The excess is most significant in the two decay modes with the best mass resolution, gamma gamma and ZZ; a fit to these signals gives a mass of 125.3 +/- 0.4 (stat.) +/- 0.5 (syst.) GeV. The decay to two photons indicates that the new particle is a boson with spin different from one.

I’ll refrain from commenting on the use of frequentist language in both these papers, but instead just comment that these extremely important papers are available for free on the arXiv. Open access, we call it.

PS. There’s an interesting blog post related to these papers, about citations in particle physics here.

Yesterday’s old photograph reminded me of this classic from Private Eye ages ago. It appeared originally in the Guardian (before it went all Helvetica). Sorry it’s a bit battered…

A Year without Columbo

Posted in Biographical, Columbo with tags , on August 1, 2012 by telescoper

It’s a year to the day since my old feline friend Columbo passed away. I still miss him, and have indeed felt his absence as strongly as ever over the last few weeks. Still, going through photographs and other memorabilia recently has not been without its therapeutic value. Here are a few pictures over the years, showing how Columbo stayed with me through many changes of hairstyle! Most of the pictures were taken in my flat in Bethnal Green during the 90s; the last one in my house in Beeston, Nottingham. The antepenultimate picture shows Columbo with my mum…


Observational Tests of Inflation, Durham 1990.

Posted in Biographical, The Universe and Stuff with tags , , , on July 31, 2012 by telescoper

I came across this old picture in my office today and couldn’t resist posting it for nostalgia’s sake. It was taken at a NATO Advanced Research Workshop called Observational Tests of Inflation, which took placed in Durham in December 1990. You’ll probably need to click on the image to be able to recognize faces, but I should at least point out Sir Fred Hoyle in the turquoise jacket in the front row; I am behind in the red and white T-shirt and black waistcoat. In those days I was considered quite trendy, among cosmologists.

You can also see George Smoot, Simon White and Alan Guth sitting next to each other in the front row.

Wavy Gravy

Posted in Jazz with tags , , , , , on July 31, 2012 by telescoper

I was looking through my collection of old CDs last night and saw a track on Kenny Burrell’s classic album Midnight Blue with the title Wavy Gravy. I hadn’t noticed the name before, but thought it might do as a theme tune for my Cardiff colleagues who work on gravy waves  gravitational waves

Anyway, the album was recorded at the Van Gelder Studio, Englewood Cliffs, New Jersey on April 06-07, 1963, and originally released on Blue Note (4123). The complete personnel listing is: Kenny Burrell (guitar); Stanley Turrentine (tenor saxophone); Major Holley, Jr. (bass); Bill English (drums); Ray Barretto (congas).
