In honor of AAPI Heritage Month, I revisited the remarkable story of Wu Chien‑Shiung — a scientist whose brilliance reshaped modern physics and whose courage challenged the boundaries placed on women in science.

Often called the “Queen of Physics” and the “First Lady of Physics,” Wu Chien‑Shiung was a Chinese‑American physicist whose work fundamentally changed our understanding of the universe. Born in China, she later earned her PhD in the United States and became a U.S. citizen in 1954. Her groundbreaking experiments disproved the long‑held belief that nature does not distinguish between right and left — a principle known as parity.

Her discovery was so revolutionary that it earned her two male colleagues the 1957 Nobel Prize in Physics, while Wu herself was excluded. Despite being nominated at least seven times before 1966, she never received the Nobel Prize during her lifetime. Her omission remains one of the most widely recognized injustices in the history of the award.

Wu was acutely aware of the gender discrimination that permeated the scientific world. At an MIT Symposium in October 1964, she delivered a powerful reflection on equality:

“I wonder whether the tiny atoms and nuclei, or the mathematical symbols, or the DNA molecules have any preference for either masculine or feminine treatment.”

As a dual national of the United States and China, Wu Chien‑Shiung not only advanced physics but also fought for social justice, fairness, and gender equality. Her legacy continues to inspire generations of American and Asian women in STEM.

During AAPI Heritage Month, her words — and her example — remind us that the pursuit of knowledge is universal, and the fight for equality is ongoing.
