Grond, Frank Halbig, Jesper Munk Jensen and Thorbjørn
Lausten are collaborating on a project entitled Sol that
was presented at ZKM Karlsruhe, Karlsruhe, in the Fall of 2004
and was displayed Esbjerg, Denmark May 2005. This project involves
transforming scientific data into media. See Data
of Two Suncycles (http://www.sol-sol.de).
For this project they used solar data spanning the last 20 years.
Four different data sets have been visualized (above, largest
image) as well as audiofied, with each set based on the following
left: Irradience, the total energy output of the Sun
Right: The solar wind
left: Sunspot numbers and positions
right: The solar magnetic mean field
magnetic mean field dataset was taken from the Wilcox
Solar Observatory, part of the Solar Observatories Group
here at Stanford.)

project Dataview shows four visualisations of the four
parameters from the
Carrington Rotations* that occured from January until September
2003. The idea was to have the solar oscillations described in
the data control the motion of several lamps and filters. The
image projected by these lamps would then change shape and color
according to the movement of the solar surface. The triangle,
cross and square seen in the picture above, left, are controlled
by MDI data taken from different points on the solar surface.
The circles in the front and lines in the rear are controlled
by data from the solar wind. To demonstrate the interaction of
two different configurations as the data visualizations proceed,
the figure was generated by two DVD-video projections beamed onto
the suspended semi-transparent screen from each side of the screen.
consists of four broad bands each of which represents aspects of
the Carrington Rotations. In the other projections, each is divided
into sections consisting of four units which again represent the
four aspects. The projections change every one second or every half
second, each representing one measurement. Each of the four visualizations
was done with a beamer and a DVD player. The duration was about
twenty minutes, then the whole thing was repeated. The project was
done in collaboration with the astophysicist Ib Lundgaard Rasmussen
from the Danish Space Research Institute, Copenhagen.
The artist, Thorbjørn
Lausten has had a long interest in the interface of art, science
and technology. He has published in the online journal Leonardo,
and was a research fellow at the Center for Advanced Visual Studies,
M.I.T.. According to Lausten, "A main intention in doing this piece,
and other pieces with visualization of scientific data, is that
there is an absolute one-to-one relation between data and visualisazition
which, among other thing, means that you give the image/projection
not only an aestetic function, but a function exactly as exact as
the data which are used, or you may say that you give the image
a logical function. I think that a main obstacle in the discussion
about the difference/s between art and science is that one does
not realize that both art and science function as representations
and that mathematics is also a symbolic language. It has been pointed
out by Max Bense that the 'semiotic sign as such', the concept of
'mathematical figure' and 'the aestetic state' all belong to the
same triadic class of signs as defined by Pierce, which, in my opinion
at least, has very wide ranging ramifications. Another main intention
was to show how important visualization is in order to understand
and construct our world be it art or science."
