  I think the Copenhagen interpretation goes beyond that. If the decay of
the radioactive substance causes the flask to be broken, killing the cat,
it has already been "observed" (by whatever detector caused the flask to
be broken) and thus there are no superimposed states, but according to
the Copenhagen interpretation there are, until some external observer opens
the box.

  That's the kind of "observation" I don't understand.
