👤 whose

Whose research first showed that parity is not conserved in the weak force?

Quick Answer

Chien-Shiung Wu led the 1956 experiment that disproved parity conservation in weak interactions. The result shocked physics.

The Full Story

Chien-Shiung Wu performed the famous cobalt-60 experiment in 1956. Her results showed that the weak interaction does not conserve parity, meaning nature distinguishes left from right at the particle level. This overturned a long-held assumption in physics and transformed the understanding of fundamental forces. Wu’s work became one of the most celebrated experiments in 20th-century physics.

Key Facts
