1991 | David Eby

Self Energy by David Eby.

"Self Energy" 2025 charcoal on watercolor paper, by David Eby '91 (HAS), appeared in the Frederick Arts Council Gallery show "Where Energy Meets Matter" in Frederick, Maryland. He started his art career at the Hartford Art school in 1991 and left for a career in the world of finance as a project manager. For the next 30 years, he eschewed artistic work, until the pressure to create became overwhelming. David’s work is heavily influenced by decades of life in the corporate world, suppressing his need to create, and imbue abstract symbols with the powerful energy of self-denial.

"Self Energy" represents the Greek symbolism of the modern lexicon as it relates to quantum field theory. In quantum field theory, the energy that a particle has as a result of changes that it causes in its environment defines its self-energy S. The self-energy represents the contribution to the particle's energy, or effective mass, due to interactions between the particle and its environment.
