In my Solitude

Posted in Jazz with tags , , , on November 3, 2011 by telescoper

Here’s a little gem for you. It’s a lovely little short version of Duke Ellington’s great song (In my) Solitude as performed by the quartet that was co-led for a short time in the 1970s by guitarist George Barnes and cornettist Ruby Braff. They may not have stayed together for very long before the two leaders had a major falling out and they split up, but they certainly produced some exquisite music while the band lasted and the “Braff-Barnes Quartet” is much celebrated in Jazz histories.

Ruby Braff’s technical ability on cornet is astonishing but  his style very traditional; he was once described as “The Ivy League Louis Armstrong”. On this tune in particular he manages to produce a smooth velvet tone in the lower register, which almost merges with the arco bass of Michael Moore, as well as  brilliant quicksilver runs in the upper register. The other member of the band was Wayne Wright who played (mainly rhythm) guitar.

This particular track proves that this band not only new how to play but also when to stop;  2:38 is pretty short for a live jazz performance but I think they stopped at just the right moment – something that quite a few bands  would do well to learn from!

Transfer Orbit

From time to time I like to post nice physics problems on here. Here is a quickie that I used to use in my first-year Astrophysical Concepts course which has now been discontinued, so I don’t need to keep it to myself it any longer.

A simple way to travel from one planet in the solar system to another is to inject a spacecraft into an elliptical transfer orbit, like the one shown by the dashed curve, which is described by Kepler’s Laws in the same way that the planetary orbits (solid curves) are.

Kepler’s Third Law states that the  period of an elliptical orbit is given by P^2 \propto a^3 where a is the semi-major axis of the ellipse. Assuming that the orbits of Earth and Mars are both approximately circular and the radius of Mars’ orbit is 50% larger than Earth’s, and without looking up any further data, calculate the time taken to travel in this way from Earth to Mars.

November Graveyard

Posted in Poetry with tags , , on November 2, 2011 by telescoper

All of a sudden it’s November and the arrival of the new month has found me in the mood for a bit of Sylvia Plath. This is November Graveyard, read by the poet herself in that uniquely unsettling voice of hers. Sylvia Plath was born in America but eventually moved to England after she married the poet Ted Hughes. Her accent sounds to me neither American nor British. Her diction, as polished as cut glass but also as brittle, is that of a person striving  to re-invent herself. And failing. Her voice sounds to me redolent with alienation, and its coldness gives this reading of this bleak poem an even harder edge than the text alone.  Plath took her own life in 1963 and was subsequently buried in the same graveyard referred to in the poem,  in Heptonstall, Yorkshire.

The text, as read, differs from some published versions:

The scene stands stubborn: skinflint trees
Hoard last  leaves, won’t mourn, wear sackcloth, or turn
To elegiac dryads, and dour grass
Guards the hard-hearted emerald of its grassiness
However the grandiloquent mind may scorn
Such poverty. So no dead men’s cries

Flower forget-me-nots between the stone
Paving this grave ground. Here’s honest rot
To unpick the elaborate heart, pare bone
Free of the fictive vein. When one stark skeleton
Bulks real, all saints’ tongues fall quiet:
Flies watch no resurrections in the sun.

At the essential landscape stare, stare
Till your eyes foist a vision dazzling on the wind:
Whatever lost ghosts flare,
Damned, howling in their shrouds across the moor
Rave on the leash of the starving mind
Which peoples the bare room, the blank, untenanted air.

Astronomy Look-alikes, No. 69

I’m struck by the resemblance between purveyor of popular comic verse Pam Ayres and Oxford astrophysicist Dr Dimitra Rigopoulou. I wonder if by any chance they might be related?

Fright Club

Posted in Uncategorized with tags , on November 1, 2011 by telescoper

Regular readers of this blog (both of them) will know that a few months ago I tried my hand at stand-up comedy at the Second Bright Club Wales (see posts here and here). Last night I went along to the latest Bright Club show, number 4 of what I hope will be a long-running series. This time it was much more relaxing for me, as I didn’t have to “perform” and was therefore not only spared the nervous tension but also offered the potential of a bit of schadenfreude. Whether it was Hallowe’en horror or stage fright that caused the impromptu renaming of last night’s extravaganza “Fright Club”. As it turned out, all the acts were very good and the audience very friendly, so despite a few nerves nobody actually died…

I know one particular contributor, our own Ed Gomez (who also blogs),  was a bit apprehensive before the show, because he told me as much. But  he needn’t have worried, as his set turned out to be as hilarious as I thought it would. My only criticism is that I was a bit  disappointed with his use of foul language. There just wasn’t enough of it. Anyhow, Ed had the prescience to record his set so here it is in all its glory….

Kudos to all the contributors last night, and to the inestimable MC Dean Burnett for directing the traffic with such aplomb. It was great fun, and as a bonus it gave me an excuse to be out of the house when the trick-or-treaters came round!
