I’m reminded again of the necessity, in certain countries, for the traveller (ie tourist) to submit to the authority of a succession of personal guides. In the Berber village of Chebika our driver and guide, Taher, passed us over to Hassan, a cheery local guide in traditional dress, who not only helped us scramble up…More
Silent night
Silence is close to noise in its effects. In his study of a Paris housing estate, the sociologist Jean- François Augoyard reports the experiences of people inside an elevator: “Dramatic evocations are set in gear on the basis of noises.” Noises invoke haunted castles, but “the most dramatic images arise with the halt of the…More
Chasing the line
I’ve just been reading anthropologist Tim Ingold’s book Lines: A Brief History (Routledge, 2007), and squaring it with my recent experience as a traveller on the Sousse to Tozeur Oasis rail line at the northern edge of the Sahara Desert. I’m reading the text as an e-book via the Kindle app on an iPhone. On the one hand the journey…More
Making a noise
There’s a sense of quiet after a snow fall, which brings to mind the importance of noise in everyday life. We think of noise as random and unattributable sounds. More technically, and as developed by mathematician and information theorist Claude Shannon, noise is any unstructured or random signal. Noisy signals are those with high entropy.…More
Computer images and realism
Computer graphics and animation are remarkable in their ability to mimic reality, or so it seems. Such technologies are interesting in so far as they purvey unreality, or more precisely, for making presentations to audiences that are unlike everyday experiences — features of narrative, drama and film in any case, but exaggerated further in the…More
Derrida and WikiLeaks
In his article Archive Fever Derrida suggests that the desire to preserve information is in some way a symptom of an inbuilt and unavoidable desire to destroy it. Drawing on Freud’s concepts of the pleasure principle and the death drive, Derrida argues that an information store (archive) on the one hand involves a desire to…More
Brain Scans and Creativity
As well as its obvious clinical applications, magnetic resonance imaging (MRI) helps researchers create maps locating brain activity during tasks such as solving puzzles, daydreaming, playing musical instruments, composing, writing and generally being creative. Knowing where something takes places provides confidence that we are closer to understanding it. This tendency to equate understanding with getting…More
Architectural remainder
Visiting Canterbury Cathedral today for only the second time in 35 years I was unsurprised to observe that this important building still has a bent plan.More
Architecture and Music
Musicians are familiar with the discrepancies evident in musical scale systems. The cycle of fifths and the cycle of octaves work together to produce a harmonious and well-ordered system of relationships between notes — almost. The superimposition of the two systems that is so essential for free and inventive modulation across musical scales in fact…More
Being David Hockney
David Hockney sends digital paintings of flowers to his friends by email. These are pictures he created on his iPhone and iPad. Some of these images are now on show at a gallery in Paris (Fleurs Fraîches at the Fondation Pierre Bergé). It’s pleasing that artists of his stature can embrace new technologies and explore…More
