When Wu Chien Shiung was born in China 100 years ago, most girls did not attend school; no one considered them as smart as boys. But her parents felt differently. Giving her a name meaning “Courageous Hero,” they encouraged her love of learning and science. This engaging biography follows Wu Chien Shiung as she battles sexism and racism to become what magazine called the “Queen of Physics” for her work on beta decay. Along the way, she earned the admiration of famous scientists like Enrico Fermi and Robert Oppenheimer and became the first woman hired as an instructor by Princeton University, the first woman elected President of the American Physical Society, the first scientist to have an asteroid named after her when she was still alive, and many other honors.
