The Fragmented Orchestra






AboutThe Project: "The Fragmented Orchestra is a huge distributed musical structure modelled on the firing of the human brain's neurons. The Fragmented Orchestra connects 24 public sites across the UK to form a tiny networked cortex, which will adapt, evolve and trigger site-specific sounds via FACT in Liverpool. Each of the sites has a soundbox installed, which will stream human-made and elemental sounds from the site via an artificial neuron to one of 24 speakers in FACT. The sound will only be transmitted when the neuron fires. A firing event will cause fragments of sound to be relayed to the gallery and will also be communicated to the cortex as a whole. The combined sound of the 24 speakers at the gallery will be continuously transmitted back to the sites and to each of the 24 sites. The sounds of The Fragmented Orchestra will vary according to location; wind over Black Fell , inner city traffic, chanting from sports stadia and the chatter of migrating birds arriving for the winter will be combined with incidental and performed sounds from members of the public. The public, invited to play the instrument at the 24 sites, will be able to hear the effect their playing has on the overall composition of the piece at each site and at FACT. As members of the public use the instrument they will become both player and audience of a vast and evolving musical composition extended across the UK. The Fragmented Orchestra — conceived by artist Jane Grant , physicist, musician and composer John Matthias and composer Nick Ryan — is the winner of the PRS Foundation New Music Award. This award is the most financially prestigious for new music in the UK and has been likened to the Turner Prize for music". (Dal sito "The Fragmented Orchestra")

Concrete Bathtub Forms

attach and remove ... Materials


is a problem in materials, is the junction. You can merge two pieces with a very strong bond, for example by welding, but then it is difficult to remove them without damaging them: that in a bit 'more "high", there was a junction irreversible.
Or you can join us so that we can remove without breaking, for example, the envelopes with the strip of adhesive paper.

What is impossible to achieve with chemical bonding, ie by interposing a substance between the two surfaces to adhere, is a reversible junction (ie where we can "change your mind" and remove the two pieces), but at the same time strong enough to withstand the weight applied to the material
cui i due pezzi originari sono costituiti.

Lo sanno bene coloro che utilizzano le colle cianoacriliche: i due pezzi si possono attaccare (da cui il nome di un marchio tra i più diffusi), il processo inverso è praticamente impossibile, ed inoltre bisogna far caso a: preparazione della superficie, quantità di adesivo usato, tipi di materiali da congiungere ed in certi casi anche alla pressione applicata (a volte serve una morsa per stringere i due pezzi).

Più in generale, la natura risolve i propri problemi di giunzione ingegnosamente, per esempio le diatomee, che sono alghe monocellulari (la foto, premiata, è di Mario De Stefano), nanostrutture di silice, si collegano the colonies to which they belong in a flexible manner through hinges very similar to lightning.
