Chien-Shiung Wu was a Chinese-American physicist who made significant contributions to the fields of physics and nuclear chemistry. Born in 1912 in Liuhe, China, Wu received her undergraduate degree in physics from National Central University in 1934 and later earned her PhD in physics from the University of California, Berkeley in 1940.
One of Wu's most notable achievements was her experiment disproving the law of conservation of parity, a fundamental principle in physics that states that physical laws should be the same for all observers, regardless of the direction in which they are facing. This principle had been widely accepted for decades, but Wu's experiment, known as the Wu Experiment, showed that it was not always true.
In the 1950s, Wu and her team of researchers performed a series of experiments involving the radioactive decay of cobalt-60. They found that the decay of cobalt-60 was more likely to produce atoms with a specific spin, a property that is affected by the law of conservation of parity. This result was a major surprise to the scientific community and helped to revolutionize our understanding of the subatomic world.
In addition to her work on the law of conservation of parity, Wu made important contributions to the field of nuclear chemistry. She developed techniques for separating isotopes, which are atoms of the same element that have different numbers of neutrons in their nuclei, and used these techniques to study the properties of isotopes and their role in nuclear reactions.
Wu's contributions to science were widely recognized during her lifetime. She received numerous awards and honors, including the National Medal of Science, the first woman to receive this prestigious award, and the Presidential Medal of Freedom, the highest civilian honor in the United States.
In conclusion, Chien-Shiung Wu was a pioneering physicist and nuclear chemist who made significant contributions to our understanding of the fundamental laws of nature. Her work helped to shape the modern field of physics and her legacy continues to inspire scientists around the world.

In 1956, Wu was approached by colleagues and theoretical physicists, Tsung Dao Lee and Chen Ning Yang, seeking her expertise in beta decay. Pupin Professor of Physics in 1973.
Gu encouraged her to pursue graduate studies in the United States and in 1936, she visited the University of California at Berkeley. In 1942, she married Luke Chia-Liu Yuan, who she had met during her studies at Berkeley. They may study theory, design and perform experiments, or apply their knowledge in developing materials or equipment. In 1944 she accepted a position at Columbia University where she did some research. Wu published her book, Beta Decay, in 1965 and it continues to be a reference text for nuclear physicists today. Accessed 02 April 2021. For two years after graduation, Wu did a graduate-level study in physics and worked as an assistant at Zhejiang University.

Wu received her elementary school education at Ming De School, a school for girls founded by her father. She protested the imprisonment in In China there are many, many women in physics. In 1939, while Chien-Shiung was still his student, he received the Nobel Prize in Physics for inventing the cyclotron particle accelerator.
A parity transformation replaces such a system with a type of mirror image. This was a boarding school with classes for teacher training as well as for regular high school. Retrieved March 3, 2021. Altogether, she received more than fifteen major awards, honorary degrees, and held at least a dozen memberships in learned societies. In 1930, Wu enrolled in one of the oldest and most prestigious institutions of higher learning in China, Nanjing or Nanking University, also known as National Central University, where she first pursued mathematics but quickly switched her major to physics, inspired by Marie Curie. Before matriculating to National Central University Wu spent the summer preparing for her studies with her usual full force.
Although she originally intended to become an artist, she was inspired to study physics after reading a biography of Marie Curie. She became a researcher at the Institute of Physics of the Academia Sinica. Wu's experiment showed that this is indeed the case: parity is not conserved under the weak nuclear interactions. Who was the first lady scientist in the world? Retrieved March 19, 2021. She was a Chinese-American experimental physicist who made significant contributions in the field of nuclear physics.

Wu officially became a U. What are 3 interesting facts about Wu? Lawrence, who would soon win the Nobel Prize for Physics in 1939 for his invention of the cyclotron particle accelerator. Is uranium a metal? Only a few years later in 1944, she left Princeton to work on the Manhattan Project at Columbia University. Accessed 02 April 2021. Wu was on the magazine cover where she was called the woman of the year in 1945 for her crucial role in the Manhattan Project. Her ashes were buried in the courtyard of Mingde School in China, the school her father started and she attended as a young girl. Tsung-Dao Lee and Chen Ning Yang, that parity — a theory that the laws of nature are not biased in any particular direction — was not conserved in certain types of nuclear reactions.
Wu studied nuclear physics at the University of California, Berkeley where she was advised by leading physicist, Ernest Lawrence. In 1990, the Nanjing Zijinshan Observatory of the Chinese Academy of Science named an asteroid after her. One example highlighting the problem was the puzzle of the theta and tau particles, two apparently different charged, strange mesons. Wu was a trailblazer in a male-dominated field and turned her struggles into opportunities at every turn. This confirmed a 1956 theory by other scientists who received the 1957 Nobel Prize in physics.
Accessed 01 April 2021. Wu was accepted by the University of Michigan, and her uncle, Wu Zhou-Zhi, provided the necessary funds. It stated that beta particles emitted by a radioactive nucleus would fly off in any given direction, regardless of the spin of the nucleus. What are 3 interesting facts about Sau Lan Wu?
