In a precision laboratory experiment, as in the filmmaking process, the close recording, and sometimes manipulation of, the passage of time can be key to success. Our August issue takes on a classic preoccupation of science fiction, time and movement through it, and extends our investigation to its other manifestations, in and out of the lab.
flow, just flow / from 20Hz by Semiconductor (Ruth Jarman and Joe Gerhardt)
20Hz observes a geo-magnetic storm occurring in the Earth’s upper atmosphere. Working with data collected from the CARISMA radio array and interpreted as audio, we hear tweeting and rumbles caused by incoming solar wind, captured at the frequency of 20 Hertz. Generated directly by the sound, tangible and sculptural forms emerge suggestive of scientific visualisations. As different frequencies interact both visually and aurally, complex patterns emerge to create interference phenomena that probe the limits of our perception.
