to effect in the physical world. If this is known we can predict the
future from the present.
This led to the development of what is known as the Hidden
Variable Theory. It assumes that if we had known the whole truth
we could retain both realism and predictability. What is lacking
in quantum theory is that we have only a part of the information.
It is the hidden variable in our knowledge that causes the crunch.
John von Neuman apparently proved through a slight twist in the
mathematical formalism that no such theories could be
developed. (This was later proved to be a false alarm based on
a mathematical error by Bell)
So Bohr put forward his complementarity principle, which led to
the Copenhagen interpretation of quantum theory.
5.3 The complementarity concept of Bohr
This proposes that the state of the system is the complete only
with the microscopic system plus the macroscopic measurement
apparatus. Then the complementary nature of wave-particle
duality, and the character of the uncertainty principle are an
intrinsic property of the nature and not a peculiarity of the
measurement process.
In Bohr's Copenhagen interpretation, it does not make any sense
to speak about characteristics of the quantum system in itself
explicitly without the rest of the wider system including the
measuring devices. It is therefore even more senseless to assign
