About The Artwork

Hand drawn ink on acid free paper. The soft colors were created by pushing the ink through the paper from the back side of the drawing. Once the colored areas were complete, the drawing was flipped over and fine line black and sepia details were added. Tortuosity is a general term describing path curvature and how often a path changes direction and doubles back. A handy way to think about it is in terms of a random walk taken by a highly inebriated person. A lot of cocktails and small steps creates a highly tortuous path. reduce the number of cocktails or increase the step size and the person's path becomes less tortuous. Tortuosity is quantified and used in areas like Polymer Physics and Gel diffusion. In Polymer Physics a long floppy molecule forms a random coil - a structure l;ike tangled shoelaces or boiled spaghetti. Al dente spaghetti coils into less tight, complex, and tortuous shapes than slightly overcooked spaghetti. Sneaker shoelaces can form tighter more complex coils than the stiffer laces used on hiking boots. Some polymers also form complex extremely flexible random coils or more extended coils which require more length to double back. The tortuosity of the coil affects some of the terms in the entropy of the polymer, which affects everything from melting to mixing to mechanical behavior.

I am offering a selection of Abstracts and abstracted Science theme work on Saatchi. Please search for me online for my Landscape and Tree of Life bodies of work. I often ask myself whether I'm a physical scientist who also paints, or a painter who has studied a bit too much physics and chemistry. Physics and Chemistry have become a big part of how I model and understand the world. I approach paint texture in terms of it's viscoelastic properties, and color in terms of pigments and their spectra. If you take a cadmium inorganic red and it's organic substitute, gently tweak them so they look almost identical in indirect daylight, will they behave differently in incandescent light? Sunlight? Late afternoon light? (controlled lab light?) Unlike people, fruit, landscapes and other traditional painting subjects, technical ideas and objects don't have an "appearance" in any normal sense of imagery. They're imagined and depicted as visual ideas that guide us through complex phenomena. For example what do like bonds in molecules really look like? Or the quantum not-quite-existence of high vacuum-spawned subatomic particles? The softly dancing dynamic structures in complex fluids? What about "things" that are too small and too delicate for even the best electron microscopes (TEM - SEMs are toys)? I've found that many images scientists create serve as visual similes to data and hypotheses, and as visual metaphors for complex and often highly abstract concepts. These metaphors and their stylized interpretation inspire and guide my "abstract" work.
