The secret lives of invisible magnetic
fields are revealed as chaotic ever-changing geometries . All
action takes place around NASA's Space Sciences Laboratories, UC
Berkeley, to recordings of space scientists describing their
discoveries . Actual VLF audio recordings control the evolution of
the fields as they delve into our inaudible surroundings, revealing
recurrent ‘whistlers' produced by fleeting electrons . Are we
observing a series of scientific experiments, the universe in flux,
or a documentary of a fictional world? |

Semiconductor's Magnetic Movie: by Douglas
Kahn
In 1744 a simple experiment was conducted in Sweden to reproduce
the underlying cause of the Aurora Borealis in a laboratory, what
we would now think of as a room. A small hole in a shade "the size
of a large pea" let through a ray of sunlight that then was
refracted through a prism. The small patch of light broken into a
spectrum of colours then traveled through a medium of turbulent air
directly above a warmed glass of aquavit. The resulting image
landed on a screen a few short feet away and looked like what was
seen dancing in the sky on many long Swedish nights, nature's
sublime entertainment in the real pre-history of cinema.
The experiment concluded that the aurora was caused by a refraction
of light through volatile vapors. Straining a rainbow through
drunken air may have not proved to be most scientifically accurate
recreation of the Aurora Borealis, but it was the "very most
beautiful thing that can be arranged in a dark room…flashing beams
shoot suddenly up and then transform into colored veils, endlessly
changing position between themselves, the one against the other."
The shift in magnitude from the scale of the earth to a miniature
in the laboratory was no doubt greased by the remaining aquavit
left undedicated to the pursuit of science.
In Magnetic Movie, Semiconductor have taken the magnificent
scientific visualisations of the sun and solar winds conducted at
the Space Sciences Laboratory and Semiconducted them. Ruth Jarman
and Joe Gerhardt of Semiconductor were artists-in-residence at SSL.
Combining their in-house lab culture experience with formidable
artistic instincts in sound, animation and programming, they have
created a magnetic magnum opus in nuce, a tour de force of a
massive invisible force brought down to human scale, and a "very
most beautiful thing."
Just as the finicky sun in Sweden was let through a small hole in
the shade in 1744, scientists at the SSL at University of
California in Berkeley theoretically model, conduct experiments,
and develop instruments to study the magnetic fields of the sun.
They study them deep inside the sun's core, their effect on the
looping of the corona flaring above its surface (the photosphere,
that lights our days), and the solar winds of charged particles
that interact with the earth's own magnetic field, creating the
auroral displays at the poles. Magnetic Movie is the aquavit,
something not precisely scientific but grants us an uncanny
experience of geophysical and cosmological forces.
With Magnetic Movie, Semiconductor have tapped into a new and
ancient aesthetic of turbulence. We can hear it in the sounds of
natural radio-naturally-occurring electromagnetic signals from the
earth's ionosphere and magnetosphere-that course through Magnetic
Movie, at times animating the animation, a quick nervous response
condensed into static. The sound itself is the product of the
combined turbulences of the earth's molten core, weather systems
and electrical storms, ephemeral ionization in the upper
atmosphere, and the solar winds. What we hear is underscored with
complex and supple orders, in fact, too complex and supple to be
ordered. We already have experience of them in the tangible
turbulence of water and the crazy convection of fluids combining,
tongues of fire and the thermal afterthought of smoke, the ribbons
of clouds stiffly blown twisted up a hill. The flux championed by
Hericlitus that has awed audiences since antiquity.
