The “real” thing...

I have always had a strong æsthetic preference for physical rather than purely electronic media in my acquisition of information content. Practical considerations often outweigh that preference when the content is utilitarian; but they never eclipse it.

I've mentioned this before, in relation to text. If I am seeking facts, or must carry a lot of content at the same time, then one or another electronic reader makes more sense than paper and ink. The reader can give me a thousand documents, or more, for the same weight and bulk as one. But when it comes to reading for pleasure, I would rather carry the bulk of a novel in paperback than the weightless downloaded version. I value the electronic reader1 (though I'm in the process of ditching it in favour of software on a tablet computer; more of which another time), but I can't love it.

So it is, too, with music. Except, of course, that I have no utilitarian reasons for choosing downloaded music over physically purchased media beyond cost and availability.

Matt Revell commented to my previous post that “The beauty of a book is, I believe, that I just need a little light and my specs to enjoy it. It's not like listening to music, where you do need some kind of equipment whether you're listening to an Ogg file or a vinyl record.” A good point, and one which reverses to the case that if one is listening to music on the move2, it makes little difference how one came by it. I never have a need to consult Stockhausen's Helikopter-Streichquartett or Craig Davis playing Sister Sadie in the middle of a meeting, the way I might have to consult legislation or published papers ... but, if I did, I could do so just as effectively from digital copies of purchased CDs (or even shellac 78s, for that matter) as from digital downloads.

Some music is no longer available on physical media. Some new music never was. In either case, I am quite happy to download it as my primary means of procurement and store it not only on my hard disk and back it up on the cloud but also save it onto a CD of my own. Much music, however, is still (so far; it may well not always be so) available for physical purchase – and I prefer to buy it that way if I possibly can.

There are the obvious advantages and disadvantages. Electronic copies are usually at a quality level compromise which is good enough and small enough for a particular purpose, and if I have the original physical medium I can go back for a better conversion at any time (see note 2 below). On the other hand, two and a half thousand albums fit as neatly in my shirt pocket as one, on a hard disk, but represent an increasingly demanding storage problem in physical form.

None of that, however, whilst true, really has much to do with my real reasons for preferring physical ownership. When it comes right down to it, my real reasons are æsthetic. I love the complete artefact which an album (or book) represents, and that is the true basis for my preferences.

There is a process of fragmentation in cultural forms, at the moment, which for the first time seems capable of excising those forms from our cultural stock. I don't suggest that there is anything wrong with fragmentation, and certainly there is nothing new about it. From my earliest reading memories, I have returned to favourite passages in a novel without reading the whole; from my first LP purchase as a teenager, I often put a disk on the turntable to play just one favourite track from an album or one favourite passage from a long work. But there is now a broad tendency to only hear the fragment, rather than choosing it from the whole. Downloading did not start this ... radio stations which play tracks from albums, arias from operas, extracts from concertos, predate downloads by a long way ... now the process has moved to the point where it is legitimate to wonder whether production of long, structurally coherent cultural forms such as the novel and its musical equivalents might not face a future redundancy.

In music, the continued existence of the long form is often (not always) tied up with the physically æsthetic object. I bought The defamation of Strickland Banks, which is an exception: while I get real pleasure from the sleeve note booklet in general, and from two of the black and white photographs in general, this is a brave attempt to carry the concept album into the new nonphysical era. Defamation relies on its narrative continuity, and planned video form, to bind itself together as a single long entity.

At the other end of the scale from Defamation, I have recently been given Emily Barker's Almanac and Kate Bush's Director's cut, both of which, in different ways, play on my desire for a physical æsthetic.

Almanac, like several other albums in its genre (Joanna Newsom's Milk eyed mender, for instance), dispenses with the usual jewel CD case in favour of a fold out cardboard one. There's a thumbnail picture of it on the left; click it for a large view showing inside and outside, including slotted disk sleeve.

This sleeve, as I hold it, triggers in me all the responses which I usually feel towards a craft object ... including books, particularly hand made books. I am aware that I am being manipulated to respond in this way; but both art and crafts are, always, manipulating our responses. I'm so glad that I don't have a download version, even though I have stored the music itself on a music player from which I listen to it without any need to go into the sleeve.

Director's cut also abandons the jewel case, but instead of a handicrafts approach it takes the form of a hardback book of the same size – with the disk itself sleeved inside the front cover. The book contains the song lyrics, but also a set of intriguing, humorously linked, photographs reminiscent of Penny Slinger meets Duane Michals (for example, the one shown on right, linked to the song lyrics for "And so is love"; again, click the image for a larger view). Many of these images depict people wearing fish heads3.

Both of these I handle with tactile and visual delight which synergises with my enjoyment of the music to produce an æsthetic whole which is so much more than the sum of its parts. The download version of Director's cut includes, in PDF form, a copy of the booklet ... but that really wouldn't (excuse the pun) cut it, for me; I would value it highly, if that were all that was available, but I value the inclusion of the "real" thing, the physical, touchable thing, so very much more.


  1. I say "electronic reader" rather than "Kindle" because the Kindle, being tied to one supplier, is both barely useful to me and philosophically less open than most of its competitors.
  2. Listening to music at home, in high fidelity, may be a different matter. By way of experiment, I downloaded and bought copies of the same Bach choral recording from the same supplier. Played through good speakers, the difference was palpable: the download lacked depth and dynamic range compared to the CD.
  3. Clearly a reference to the Fish Heads label on which Bush's holding companypublishes her music. This sort of play is not isolated. The holding company itself is "Noble and Brite"; Bush's son, around which much of her life and one explicit song title revolve, is "Bertie", short for "Albert"; and the name Albert means "bright, famous, noble..."

Quote, unquote

Today I sat in an audience and heard a speaker say, amongst many other things over a period of forty minutes, the following:

“Socialisation is a process which delivers benefits to all, even the least fortunate, which nobody in their right mind (least of all I) would give up. Unfortunately, part of the price for those benefits is to convert a significant proportion of a predominantly bright, intelligent, curious population of five year olds into dull, prefrontally lobotomised eighteen year olds. For some, too few, education serves to slow down, arrest, reverse or even prevent that conversion process. For a greater proportion, education is part of that process. For others, possibly the largest (and maybe the saddest) proportion, it has no obvious effect in either direction. We badly need to seek ways of increasing the size of the first group at the expense of the other two.”

The speaker was, ten years ago, a fourteen year old education system reject from a "sink estate", whom I met in an urban outreach scheme made possible by an enlightened and far sighted café owner. Today he is a graduate with a first class honours degree in hand, not much money in the bank, but five years of passionate dedication under his belt to helping a new generation of education system rejects to reconnect with their "bright, intelligent, curious" five year old selves.

Some people make me proud to be human; the speaker, and the café owner who was also in the audience, are two examples.

Grace

No, it's not one of my own photographs this time.

It comes to me from Judith, who regularly sends me views into her world (see, for example, here).

I love this one.

It carries a different channel from the usual perceptions of several different realities, all at once, gently posing questions about all of them.

In particular, it proposes a better world than the one in which I am working today.

Since it arrived I've visited it several times, returning refreshed on each occasion.

A healthy approach to data analysis

As this appears, by a happy piece of synchronicity from my point of view, the Wellcome Collection in the UK has on show an exhibition called Dirt: the filthy reality of everyday life. One exhibit in particular is of pivotal relevance to data analytic epidemiology: Dr John Snow’s so called "ghost map". In 1854, using what would today be described as data visualisation, Dr Snow plotted cases of cholera on a map of Soho, London. From the results he deduced that a water pump, was the source of infection. This was particularly impressive because water was not, at the time, suspected as a transmission vector and the pathogenic germ theory of disease had not become generally accepted. The local council decision to disable the pump was therefore, in the circumstances, a seminal act of faith in datacentric deduction over conventional wisdom.

Seemingly unlikely causation chains are often discovered by more sophisticated variations on Snow’s theme, emerging through statistical winnowing of gathered data. More than most data analytic areas, epidemiology can benefit from pooled work by numerous users at the sharp end of their practice as well as high level overviews, and data analysis is vital across that whole range. Those who have me in preparing this article include theatre nurses, general practice managers, country vets and hospital porters.

In a more recent high profile example, again involving cholera, an outbreak in Haiti after the devastating earthquake seems to have been traced¹ to a tragic “confluence of circumstances” arising from the aid effort itself. Identification of the apparent initial import vector didn’t require any sophisticated analysis in this case, but patterns of spatial spread within the country subsequent to that were a different matter. In an unfunded study of data from census and hospitalisation records (using Madonna software, widely used software from the University of California at Berkeley) Tuite and others² were able to model transmission in a way which “Despite limited surveillance data ... closely reproduces reported disease patterns”.

I would like to thank Dr Brian Corden for invaluable help in assessing an item which, as a result of his advice, was not eventually used. He thus saved me from making a fool of myself through lack of confidence in my own judgment

California arsenic dreaming

For at least as long as I've been reading it, speculative fiction has been proposing alternative biochemistries to the carbon based one which we know and love.

My first encounter with the idea was in one of Isaac Asimov's Wendell Urth mysteries, written when I was three years old though I didn't read it until I was ten. The talking stone, in which a race of "siliconies" live amongst the asteroids, posits a silicon based biochemical economy which, I later discovered, was popular with other writers and speculators too.

Another candidate is phosphorus which, like carbon, can (in combination with nitrogen) form a variety of complex molecules including long chains and phosphazene rings. But phosphorus also has a more conventional rôle in our own carbon based scheme of things, as one of the six main elements from which living matter is constructed. Amongst other things, phosphorus is a component in the cell's energy storage mechanisms, and in the binding together of DNA. Could phosphorus be replaced within our carbon ecology?

I am, as said recently, a mediocre chemist at best (and most chemists would describe me even less charitably than that), so I'm not in a position to have opinions on these speculations, but that doesn't stop me being interested. So, I was intrigued by an article in Science (organ of the American Association for the Advancement of Science) at the end of last year, positing a bacterium which had pulled exactly this trick: substituting arsenic for phosphorus.

As the authors point out, instances of biochemical substitution for trace elements are not unknown, examples being “tungsten for molybdenum and cadmium for zinc in some enzyme families and copper for iron as an oxygen-carrier in some arthropods and mollusks”. This would, however, be the first known example of substitution for one of the big six. Trace element substitutions rely on close similarity between the usual supects and their surrogates, and the authors argue for the same sort of similarity here:

“Arsenic ... is a chemical analog of phosphorus, which lies directly below [it] on the periodic table. Arsenic possesses a similar atomic radius, as well as near identical electronegativity to [phosphorus. The most common form of [phosphorus] in biology is phosphate ... which behaves similarly to arsenate over the range of biologically relevant pH and redox gradients. The physico-chemical similarity between [arsenate] and [phosphate] contributes to the biological toxicity of [arsenate] because metabolic pathways intended for [phosphate] cannot distinguish between the two molecules ... ... ... given the similarities of [arsenic] and [phosphorus] ... we hypothesized that [arsenate] could specifically substitute for [phosphate] in an organism possessing mechanisms to cope with the inherent instability of [arsenate] compounds.”

They then went on to identify a naturally occurring organism, a bacterium in a California lake, in which this substitution seemed in fact to have occurred.

My attraction to this is. of course, a potent amalgam of intellectual curiosity and childhood dreams. Alas, a number of comments in yesterday's issue (they are also available on the Science web site) dispute or question the findings. The authors respond; the debate continues...

As a nonchemist academic, I can only wait impartially for the final verdict. As a childhood dreamer, however, I surreptitiously cross my fingers and hope for that verdict to vindicate the original findings.

How she brought the nightmare from Wasilla to DC

Gayle Reynolds just flagged up for me (under the email subject line "When is her 15 minutes up?") Sarah Palin's confused notion of Paul Revere's midnight ride.

I have to confess a stab of sympathy (my first ever) for the increasingly bizarre Ms Palin since I always found it difficult, at school, to separate the rides of Paul Revere, Dick Turpin, John Gilpin, and the good news from Ghent to Aix. (Not to mention, much later in my life, deceased minuteman Mudsy Muddlemore, the Funky Phantom...)

Alas ... nowhere is it written that being confused and bizarre will prevent someone from attaining great political power.
