Eye of the Mind

This series is based on images that were not seen directly, but which required some intermediary apparatus to make them visible.

Analog Interpolation / Scale

Many of the source images used for the paintings are quite low-resolution.  This is sometimes due to the size/bandwidth limitations of web-published images, but is also an intrinsic quality of numerical simulations, where computing resources scale exponentially with resolution.

The limitation of information in the source is a fascinating issue for me as a painter, as I am forced to use the material properties of paint to simulate and interpolate (i.e. fabricate) the missing detail.  Paint is wonderfully analog.

In his book Chromophobia, David Batchelor discusses the bias against color that he sees in many aspects of Western culture.  Color is suspect in science precisely for the reason that it is endlessly fascinating to a painter - because it carries a limitless range of associations and references, cultural and art-historical.  Scientists love color for its ability to represent information, but are wary of any use of it that might be "subjective"

2D - 3D - 4D - 5D - 6D

A color movie is a  4D representation of colored 2D slice evolving in time.  Actual information is generally at least 6-dimensional (3D spatial grid, in time, in color, selected from range of attributes (e.g. temperature, vorticity, etc.)  Visualization is an essential technique to make sense of the vast arrays of data produced.

Fluid movement shapes almost everything that does not have a rigid structure (and much of what does)  Painting these images reproduces in a way the same forces of fluid dynamics that are in play.  The randomness and accidental quality of the interactions of the liquid paint has the effect of simultaneously degrading and enhancing the original images.

The scale of the images ranges from the cosmic (Cold, Dark) to the stellar (SN1a) to the everyday to  the microscopic (DNS#1) to the molecular (DNA):

Some paintings are based on visualizations of theories of quantum gravity -- essentially, these are representation of the symmetry structures that might underlie everything.
