Heisenberg discovered something at the particle level with regard to uncertainty.
He was trying to measure, either position or momentum, or both
and came upon it.
What the principle says is that we cannot measure the position,
and momentum of a particle with absolute precision.
The more we know one measure, say 'position', the less accurately
we know the other: 'momentum'. Conversely, the more we know about momentum
and implying for a moment, direction, the less we know about position.
Where are you? Where are you going, and how fast?
How will you know when you get there?
Will you collide? With who? When?
Will there be a spark?
I find humans are certainly uncertain.
Uncertain of any position,
lost all momentum.
Picking up by bootstraps,
towards a foggy notion of direction and destination.
traveling blithely through life
singing Soul Coughing, "I knew the gas was gone,
but I had to rev the motor"
Picking up speed,
not knowing any GPS whereabouts,
No position, on anything
floating past random particles,
not necessarily colliding
nor near missing
just an uncertain particle orb
soon to fade away
