I am a biologist and a naturalist.
I understand, at least on a basic level, how iridescence works.
I understand that it can be created structurally or through diffraction.
I understand that it is the inevitable result of light hitting a certain type of surface.
I understand that it is simply physics.
But I don't care.
As I watched a male Anna's Hummingbird turn his head toward me today, I could only think of one word to describe what I was seeing.
