OF THE MICRO-WORLD

1 . ABSTRACT
Quantum mechanics is the theory used to 'describe' the processes that take place
in the micro-world. From the start quantum mechanics has been a 'strange' theory, in the
sense that it seemed to contradict in various ways the image of a micro-world consisting
of 'objects' moving around in a three dimensional space, and interacting with each other
in this three dimensional space. So from the advent of the theory a lot of disagreement
existed as to the 'physical meaning' of this quantum theory, and a lot of discussions of a
philosophical nature have taken place among the founding fathers. Only however during
the last years experiments have been performed that, independently of the strangeness of
the quantum theory, confront us directly with the strangeness of the reality of the micro-
world. We have in mind the experiments on the EPR problem.
