Early Life and Education

Wu was born on May 29, 1912, in Liuhe, China. From a young age, she displayed an exceptional aptitude for science and mathematics. Despite the cultural norms that discouraged women from pursuing careers in these fields, Wu's parents supported her academic ambitions.

In 1929, Wu enrolled in Soochow University in Suzhou, China, where she studied physics. She graduated with honors in 1934 and earned a scholarship to continue her studies at the University of Michigan in the United States.

Nuclear Physics Research

At Michigan, Wu worked under the guidance of the renowned physicist Samuel Goudsmit, who recognized her talent and mentored her in nuclear physics.

After graduating with a doctorate in 1940, Wu returned to China and joined the faculty of National Tsing Hua University in Beijing. However, her research was interrupted by the onset of World War II. In 1944, she fled to the United States, where she joined her former mentor, Goudsmit, at Columbia University.

At Columbia, Wu played a pivotal role in the development of the atomic bomb during the Manhattan Project. She also conducted groundbreaking research on beta decay, the process by which an unstable radioactive nucleus emits an electron or positron.

Parity Violation Experiment

In 1956, Wu conducted an experiment that shattered the long-held belief in parity conservation, which stated that the laws of physics treat left and right equally.

Wu's experiment involved studying the beta decay of cobalt-60 atoms, which emit electrons. She discovered that the electrons were preferentially emitted in one direction, violating the principle of parity conservation.

This discovery was a major breakthrough in physics, earning Wu international recognition and the prestigious Wolf Prize in Physics in 1978. It also led to the development of new theories, including the weak interaction, which is responsible for certain types of radioactive decay.

Advocate for Women in Science

Throughout her career, Wu was an outspoken advocate for women in science. She served as a role model and mentor for countless young women, encouraging them to pursue their dreams in STEM fields.

In 1984, she founded the Wu Foundation, a non-profit organization dedicated to supporting women entering science and engineering.

Legacy

Chien Shiung Wu passed away on February 19, 1997, leaving behind a towering legacy as a pioneering nuclear physicist, a champion of gender equality, and an inspiration to generations of scientists.

Her groundbreaking work on beta decay and parity violation revolutionized our understanding of the atom and paved the way for countless scientific discoveries.

Today, Wu's legacy lives on through the numerous institutions, scholarships, and awards that bear her name. She is remembered as a brilliant scientist, a courageous trailblazer, and a role model for all who strive to break down barriers and pursue their dreams.
