Question: Wu experiment was conducted by thi s Chinese American physicist who made significant contributions in the field of what
Context: Dr. Warren Henry (February 18, 1909 – October 31, 2001) was an American physicist who made significant contributions to the advancement of science and technology and education, training and mentoring several generations of physicists.  Nearly seven decades of work in the fields of magnetism and superconductivity have earned him praise as one of the most eminent African-American scientists in U.S. history. Major contributions to the science of microbiology have spanned the time from the 17th century to the present day.  The following is a list of prominent microbiologists who have made significant contributions to the study of microorganisms.  Many of those listed have received a Nobel prize for their contributions to the field of microbiology.  The others are typically considered historical figures whose work in microbiology had a notable impact in the field.  Those microbiologists who currently work in the field have been excluded unless they have received recognition beyond that of being on the faculty in a college or university. The Wu experiment was a nuclear physics experiment conducted in 1956 by the Chinese American physicist Chien-Shiung Wu in collaboration with the Low Temperature Group of the US National Bureau of Standards.  The experiment's purpose was to establish whether or not conservation of parity ("P"-conservation), which was previously established in the electromagnetic and strong interactions, also applied to weak interactions.  If "P"-conservation were true, a mirrored version of the world (where left is right and right is left) would behave as the mirror image of the current world.  If "P"-conservation were violated, then it would be possible to distinguish between a mirrored version of the world and the mirror image of the current world. Anna Mani (23 August 1918 – 16 August 2001) was an Indian physicist and meteorologist.  She was the Deputy Director General of the Indian Meteorological Department.  She made significant contributions in the field of meteorological instrumentation.  She conducted research and published numerous papers on solar radiation, ozone and wind energy measurements. The Organization of Chinese American Women (abbreviated as OCAW) is a national nonprofit, nonpartisan organization dedicated to advancing the interests of Chinese American women in the United States and increasing awareness of issues affecting them.  It was founded in 1977 by Pauline Tsui, and is headquartered in Washington, D.C.  At first it was affiliated with the Organization of Chinese Americans, but it was regarded as an auxiliary rather than an equal partner, and the two groups had different priorities, so they broke apart in 1987.  In contrast to the Organization of Chinese Americans, which is mainly a political advocacy group, the Organization of Chinese American Women primarily provides services and assistance to its members.  It is supported by membership, private donations and public grants.  Its mission statement reads "To advance and to advocate for the needs and concerns of Chinese and other Asian Pacific American women by helping to improve their educational, economic, social, and political opportunities, and by recognizing their excellence, leadership, and contributions to the quality of life." Tim Wu is an American lawyer, Isidor and Seville Sulzbacher Professor of Law at Columbia Law School, and contributing opinion writer for the New York Times.  He is best known for coining the phrase network neutrality in his 2003 paper "Network Neutrality, Broadband Discrimination", and popularizing the concept thereafter.  Wu has also made significant contributions to antitrust policy and wireless communications policy, most notably with his "Carterfone" proposal. The University of Michigan Athletic Hall of Honor, founded in 1978, recognizes University of Michigan athletes, coaches, and administrators who have made significant contributions to the university's athletic programs.  To qualify for induction into the Hall of Honor, an individual must have been an All-American, set an NCAA, U.S., or world record, won an NCAA title, or made significant contributions to the university's athletic department as a coach or administrator.  The nomination and selection process is conducted by the Letterwinners M Club executive board. Chien-Shiung Wu (; May 31, 1912 – February 16, 1997) was a Chinese-American experimental physicist who made significant contributions in the field of nuclear physics.  Wu worked on the Manhattan Project, where she helped develop the process for separating uranium metal into uranium-235 and uranium-238 isotopes by gaseous diffusion.  She is best known for conducting the Wu experiment, which contradicted the hypothetical law of conservation of parity.  This discovery resulted in her colleagues Tsung-Dao Lee and Chen-Ning Yang winning the 1957 Nobel Prize in physics, and also earned Wu the inaugural Wolf Prize in Physics a mere two decades later in 1978.  Her expertise in experimental physics evoked comparisons to Marie Curie.  Her nicknames include "the First Lady of Physics", "the Chinese Madame Curie", and the "Queen of Nuclear Research". David Adler (April 13, 1935 – March 31, 1987) was an American physicist and MIT professor.  In condensed matter physics, Adler made significant contributions to the understanding of transition-metal oxides, the electronic properties of low-mobility materials, transport phenomena in amorphous materials, metal-insulator transitions, and electronic defects in amorphous semiconductors. Cao Zhiyun (), born in Jinhua, Zhejiang in 1961 is a Chinese linguist and dialectologist and is a professor at Beijing Language and Culture University.  He is most well known for his work as the primary editor of the groundbreaking 2008 "Linguistic Atlas of Chinese Dialects" but has made numerous other significant contributions to Chinese dialectology with a focus on the Southern Wu varieties in and around his native Jinhua.  Despite his focus, his works exhibit an all around thorough and in-depth understanding of all Chinese dialect families and contemporary linguistics and is widely regarded in the field as one of China's leading authorities on Chinese dialectology.
