At Art in Action a gentleman stopped in front of my table. He spread his hands in an open gesture, smiled.
"I have to tell you," he said, " I am completely in awe of your work."
What can you say to so open a statement but "thank you."
"What is it that you do?" I asked.
" Oh, me? I'm only a physicist," he replied.
Earlier in the day I had been talking to Judy about rainbows and she told me that scientists had trapped part of a rainbow in a piece of glass. I had begun to worry, for if a butterfly could cause a storm across the world with a flap of its wings what might happen if light were alive in ways we didn't understand and a rainbow went to find and free the part of itself that was trapped. A rainbow dragon. Is it right to trap and enslave light?
I am in awe of physicists and wish that when I was at school I had understood the relationship between art and science better.
Later that day, a rainbow, wild and free, arced across the site at Art in Action.
The links above are to an article in New Scientist and other pages on rainbow trapping. There are almost images of the light, held in its prison if you google 'trapped rainbow'
