The remark on {{w|Parity (physics)|parity conservation}} and cobalt-60 is likely a reference to the {{w|Wu experiment}}. In 1956, physicist {{w|Chien-Shiung Wu}} and her team at the {{w|National Bureau of Standards}} used {{w|cobalt-60}} to show that the {{w|weak interaction}} breaks parity: beta particles leave the decaying nucleus in the direction opposite to nuclear spin. | The remark on {{w|Parity (physics)|parity conservation}} and cobalt-60 is likely a reference to the {{w|Wu experiment}}.
