Heisenberg was uncertain on principle
He wasn’t sure if Hitler was invincible.
He went to see Bohr
During the war,
But we’re not terribly certain what for.
Heisenberg’s world was certainly fragmented.
His uncertainly thought-out ethics were splintered
If he chose not to see
What went on in Germany
I wonder what uncertainty means?
He couldn’t deny with certainty.
Concentration camps were not a rarity.
But he trembled unsure
Right through the War,
So maybe that’s what uncertainty’s for.
I guess uncertainty was not as bad
As the total denial some of us had.
Painful to tolerate,
And on nuclear bombs to concentrate.
Whilst most certainly wanting Bohr for a mate
