Broadly speaking, both physics and art are ways of exploring and expressing perspectives about our world or the universe. While visual art operates on a system of visual, conceptual, and societal cues, physics operates on a system of mathematics and scientific methods.

Liu's long term project in art/physics "integration" is an attempt to construct a framework that are conceptually and mathematically rigorous while maintaining an interesting and powerful aesthetic ("intuitively beautiful") -- eventually even maybe the artistic insights in his work can be translated to scientific discovery.

He has been exploring this theme as early as his high school year from 2003 and has discovered various techniques of art-making since. Liu's work at Harvard cumulated in a summa, prize-winning undergraduate dissertation, Explorations in Classical Magnetism and Contemporary Art – “Amplified Mapping of Dipole Moments Through Magnetoresistance Sensors, Analog Differentiation Techniques and Ferromagnetic Fluids” and “Experiments in Painting with Magnetism”, that solidified an art/physics framework in the classical magnetism domain of physics and presented a series of innovative artworks utilizing magnetic fields and experimental physics techniques.

Currently, Lewis is exploring deeper ideas involving General Relativity, modern quantum mechanics, and wave phenomena.
