 Curie applied the above statements to determine the symmetry characteristic of physical quantities such as a polar vector, a force or an electrical field, ''A''<sub>&infin;</sub> &infin;''M'',  an axial vector or a magnetic field, (''A''<sub>&infin;</sub> /''M'') ''C''.
-If one now considers a phenomenon resulting from the superposition of several causes in the same medium, one mau note that the symmetry of the global cause is the intersection of the groups of symmetry of the various causes: the asymmetries add up. This remark can be applied to the determination of the point groups where physical properties such as [[pyroelectricity]] or [[piezoelectricity]] are possible.
