ABSTRACT
At the time the EPR paper was written, John Bell was not yet in high
school. The EPR paper was aimed against the Copenhagen (Bohr,
Heisenberg) interpretation and proposed a crucial experiment that
was modified later to make it more feasible. That modified exper-
iment was performed by many groups. Two of these experiments
are described below: that of the Aspect group in France and that of
Zeilinger’s group in Austria. These experimental investigations, their
experimental setup, and theirmeasurement procedurewere already
influenced significantly by John Bell’s suggestions and findings.
The following sections summarize the EPR-Bohr controversy, the
Aspect and Zeilinger experiments, and Tony Leggett’s seminar that
weaved it all together with John Bell’s work. Bell’s work and the
experimental results form the basis for all claims that the EPR paper
is flawed and that Einstein was not right with his negative opinion
about the use of probabilities in science.
