Meditating on Invisibility: When Light Meets Glass

It is easy for us to imagine an instance in which the invisible meets the visible. Imagine a beam of light, which is normally invisible, striking a reflective surface and bouncing into our eyes. The light that was invisible is now visible. From our perspective as observers, it has been transformed.

Now please imagine an instance in which the invisible meets the invisible. Imagine light striking glass. If the glass is perfectly transparent, it is virtually invisible. When a beam of light strikes it, we will have no way of knowing.

Has the light been transformed by its passage through the glass? Laser ray through my quartz glass rod?  Or are we merely incapable of perceiving its transformation?

Perhaps those questions seem superfluous or overly philosophical. But when you work as a sculptor with light and glass, those questions become concrete and absolutely fundamental.

There’s a point at which the interaction of light and glass becomes a meditation. As an artist, I need to understand the physics of a problem before dealing with it creatively. Sometime the leap from physical science to artistic creativity comes quickly, and sometimes it happens slowly.  I can rarely tell in advance whether the creative process will begin sooner or later; not knowing is a constant source of both frustration and joy.

I can tell you this with certainty: It’s the imperfections in the medium – the scratches in the glass – that make the work interesting. Without those scratches, even when they are infinitesimal, we would have no way of seeing the interaction between light and glass.

Sometimes the best way to talk about the physics of glass and light is with poetry. Here is a short poem I wrote to express my fascination with the awesome power of glass and luminescence. I hope you enjoy it:

nothing turns into something
the invisible is made visible
I am still chasing
after radical radiance
or the shiniest shining
is chasing after me
I seek the energies
I seek the synergies
between people
I seek the energies
which could make paper sheets fly
and I get the answers
from my dreams
at night
