Electromagnetism flies through space --
The sun releases it and it reflects
Off objects when it's certain waves, which grace
Our eyes -- though some of it each eye deflects.
The light provides electrons energy
And reconfigures retinol whose change
Creates cascades of electricity
Down neural pathways sight will rearrange.
And yet we see what we anticipate --
We mostly just confirm -- our brains construct
The world from fragments that they can relate
To instincts, concepts, what they can deduct.
Blue morpho butterflies, electric blue
And black, glisten in the sunlight and dew.
