... characterized by the same quantum numbers such as mass, charge and spin, are in principle indistinguishable. From the indistinguishability of particles follows that if two coordinates in an N- particle ... starting point in our understanding of atomic physics, condensed matter physics and chemistry. It furthermore plays a fundamental role in the studies of the nature of stars...
