The Uncertainty Principle

His mind took flight
And his eyes have lost their light
All we have to go on is a note

They changed the world last night
Working together, side by side
His father is the only one who knows

You haven′t been told?
That was his mother on the phone
There was a tragedy last night

His father can't have been here
It had to be a ghostly dream
For at the fall of day he took his life!
