English: Creator: Beutler, Margarete 1876-1949
Subject: Wu, C. S (Chien-shiung) 1912-1997 Lee, Y. K Mo, L. W Columbia University Type: Black-and-white photographs Date: 1963 3/20/1963 Topic: Physics Van de Graaff generator Women scientists Local number: SIA Acc. 90-105 [SIA2010-1508] Summary: The experiments of Columbia University physicists (left to right) Chien-shiung Wu (1912-1997), Y.K. Lee, and L.W. Mo confirmed the theory of conservation of vector current. In the experiments, which took several months to complete, proton beams from Columbia's Van de Graaff accelerator were transmitted through pipes to strike a 2 mm. Boron target at the entrance to a spectrometer chamber Cite as: Acc. 90-105 - Science Service, Records, 1920s-1970s, Smithsonian Institution Archivess Persistent URL:Link to data base record Repository:Smithsonian Institution Archives View more collections from the Smithsonian Institution. |

JPEG文件註 | Acc 90-105, Box 26, Folder "Wright, Frank Lloyd- Wu, Kuo Cheng"; "Columbia Scientists Confirm New Theory In Nuclear Physics: Dr. Chien-Shiung Wu (left) and her associates, Dr. Y.K. Lee and L.W. Mo (right), are shown conducting their experiments which led to a confirmation of the theory of conservation of vector current. In the experiments, which took several months to complete, proton beams from Columbia's Van de Graaff accelerator were transmitted through pipes to strike a 2 mm. Boron target at the entrance to a spectrometer chamber. The theory confirmed by the Columbia experiements deal with a type of sub-atomic behavior known as ""weak interaction."" one of nature's four basic kinds of physical interaction. Many laboratories throught the country have been attempting to confirm the theory since its formulation in 1958. Dr. Wu has been cited as one of the world's foremost experimental physicists. 3.20.63 # 9847" |
