Silicon

The sand is swirling in the wind--I grasp
The sand here in my hand and with a flash
Of lightning spark and flatten it and send
Another lightning surge to make it dash

Into a simple form of thought, if/then,
And/or, a simple switch and route, a one
And none to make this simple sand a flow
To calculate each aspect of the sun

And planets, galaxies, and other simple
Things crossing paths across the cosmos strands
In images of neurons neurons image
To help us calculate the swirling sands.
