| | The Fall of Parity |
 | | The title, introductory paragraph, ``Parity: What's Not Conserved?'' and certain other material in the exhibit presented here are taken from, or based on, the NMAH exhibit by Paul Forman, curator for modern physics at NMAH, Smithsonian Institution. |
 | | Thus this experiment brought about the fall of parity from its exalted position alongside such well conserved physical quantities as energy, momentum, and electric charge. |
 | | They constructed their theories so as to ensure that the corresponding mathematical property, called parity, remains unaltered - is conserved - in all subatomic processes. |
