  The discovery of quantum mechanics at the beginning of the last century led
to a revolution of the physical world view. Modern experiments, made possible
by new techniques on the border of the classical and the quantum regimes offer
new insights and better understanding of the quantum world and have impact on
technical development. Therefore it seems important that students gain
appreciation of the principles of quantum mechanics. A suitable way seems be
the treatment of the EPR-experiment at a prominent place.
