A little ditty...

[nadriel]

Schrodinger's cat and Wigner's friend
Cause us problems without end

The cat is both alive and dead
In math that is stuck in our head

And the regression of Von Neumann
Never ceases to annoy Man

The uncertainty just has no end
Until Wigner goes to tell his friend

For, until the friend recieves the news
That the cat still purrs and mews

The cat remains (suspended Fate!)
In some formal Eigenstate

But if Wigner makes a beeline
To report the now-dead feline

All the friend can really know
Is just one branch of time's swift flow

For in Carter's multispace
Every time-branch has its place

So the cat remains alive
In the half cases (that's .5)

Lead us not to Copenhagen
Nor to Shylock, nor to Fagin

"The result's not parsimonious!"
Yet I find it quite harmonious
