Chien-Shiung Wu was educated in China and the United States. She initially studied at the National Central University in Nanjing, China, before moving to the U.S., where she earned her Ph.D. in Physics from the University of California, Berkeley, under the guidance of physicist Ernest Lawrence, a Nobel laureate.

Chien-Shiung Wu had a profound impact on women in science, serving as a trailblazer and role model who demonstrated that women could achieve excellence and leadership in physics. Her success challenged prevailing stereotypes and inspired future generations of female scientists to pursue careers in STEM fields despite gender barriers.

Beta decay is a type of radioactive decay in which a beta particle (electron or positron) is emitted from an atomic nucleus. Chien-Shiung Wu's research is closely related to beta decay as she conducted pivotal experiments on this phenomenon. Her work in this area, especially her findings on the non-conservation of parity, has greatly contributed to modern nuclear physics.

No, Chien-Shiung Wu was never awarded the Nobel Prize, despite her pivotal role in the discovery of parity violation in weak interactions, which led to Tsung-Dao Lee and Chen Ning Yang receiving the Nobel Prize in Physics in 1957. The oversight is often cited in discussions of women who were overlooked for the Nobel Prize.

Yes, Chien-Shiung Wu published many influential papers, particularly in the field of nuclear physics and beta decay. She also co-authored a well-regarded textbook titled Beta Decay, published in 1965, which became a staple in the study of nuclear physics.

Chien-Shiung Wu was born on May 31, 1912, in Liuhe, a small town near Shanghai in China. Her family valued education highly, which was somewhat uncommon for girls at the time. Encouraged by her parents, she excelled in her studies and developed a passion for science, eventually leading her to pursue higher education in physics.
