[Histonet] observer's paradox
Rene, phillip et al....
Schroedinger's cat, Heisenberg's uncertainty principle and the
Westinghouse effect are all versions of the same thing, namely that
the observation or measurement itself affects an outcome, so that it
can never be known what the outcome would have been if it were not
