A fundamental concept in physics referring to the symmetry of a physical system under spatial inversion, where the system remains unchanged when all spatial coordinates are reversed (x → -x, y → -y, z → -z). Also known as parity symmetry.

  1. Physical symmetry principleC2formal

    The principle that the laws of physics are invariant under a transformation that reverses the spatial coordinates (parity transformation).

    • Space-reflection symmetry was long assumed to be a fundamental law of nature.
    • The violation of space-reflection symmetry in weak interactions was a major discovery.
    • Experiments confirmed that space-reflection symmetry is not conserved in certain nuclear reactions.
