Scientific Visualizations and Mixed Realities at the Art/Science Nexus

What is it, one might ask, that motivates an artist to position their practice at the art/science nexus - a random moment of eccentricity perhaps; or a more considered alignment with a discipline reputed to involve a systematically organised body of knowledge? Conceivably it could be argued that, if science is defi ned as knowledge gained by the study of the physical world, aware and interested individuals fall within the category of "scientist" in the manner of the erstwhile "natural philosopher".
