Victim of a great dilemma:
If precisely I can place
A particle in time and space,
Then, and to my great chagrin,
I can't determine its true spin.
If its momentum I can find,
Then it drives me out of mind,
I go bananas to think that
I can't determine where it's at...”
Finally, he said, ”That does it.
I think a principle I'll posit!”
It brought him recognition, fame,
“Uncertainty” 's his middle name...
