C SWu was a Chinese-American experimentalist, best knownfor her path-breaking experiment that showed that parity isnot conserved in beta decay. Her results gave a deeper insightinto the nature of weak interactions and enabled the correctformulation of the theory behind such interactions. She was apassionate advocate of women entering into hitherto ‘forbidden’fields of physics and mathematics and was as outspokenagainst gender discrimination as she was concerned about environmentalconservation. It was generally felt that she wasoverlooked for the Nobel Prize, perhaps because she was awoman, and a Chinese one at that.
