Ring Tones

Bartholomäus Traubeck created equipment that would translate tree rings into music by playing them on a turntable. Rather than use a needle like a record, sensors gather information about the wood’s color and texture and use an algorithm that translates variations into piano notes. The breadth of variation between individual trees results in a individualized tune. The album, appropriately titled “Years,” features spruce, ash, oak, maple, alder, walnut, and beech trees.

Superconductor Sonics

A new experimental sound-source:

… in 1987, a totally unexpected revolution took place: a new family of superconductors based on copper and oxygen smashed all records, taking the highest known superconducting temperatures up to a balmy −150C. BCS theory, which worked so well for simple, elemental superconductors, couldn’t explain the behaviour of these new materials. […] A paper published last week brings us a step closer to understanding how these new superconductors work. Physicists, including my old officemate Paul, used some of the biggest magnetic fields on Earth to try to work out what’s happening inside these materials. In fact, the pulsed magnets used burn through enough energy to melt a tonne of steel every second. […] … the mechanism that underlies this advanced physics apparatus for measuring materials in massive magnets is almost identical to a theremin. …
