What is light? Can you hear it? Is it who you are? Sometimes I feel so innately connected with light that I can barely discern between my material or more tangible aspects and this force of electromagnetism. In a beautiful poem called "On Turning Ten," poet Billy Collins writes:
It seems only yesterday I used to believe there was nothing under my skin but light. If you cut me, I would shine.
Having just spent a week in Gothenburg, Sweden, I feel that indeed we are inseparable from light. We are this electromagnetic force that we see as light, that we feel on and under the skin of our body.
