Answer
Chien-Shiung Wu, a renowned experimental physicist, played a pivotal role in experimentally demonstrating the parity violation. This breakthrough challenged the long-held assumption of parity symmetry in physics. Through meticulous experiments, Wu provided concrete evidence that certain subatomic processes do not exhibit mirror symmetry. Her groundbreaking work shattered conventional beliefs and paved the way for further advancements in our understanding of the fundamental laws governing the universe.
