conceptualized as a form of symmetry ,
representing the fact that no fundamental distinctions can be observed between right -
handed and left -
handed systems of particles in their interactions ,
and supported by the typical observation that the total parity of a system is unchanged as particles are created or annihilated ;
however ,
certain interactions involving the weak force have been shown to violate the principle of conservation of parity .
