... A Coolidge X-ray tube produces X-rays that result from the collisions between fast-moving electrons and a metal target. The electrons are emitted from a heated cathode (thermionic emission) and are accelerated towards the target by a p.d. The target is cooled. The intensity of the X-rays is increase ...

... known, uranium. The dimensions of this tiny solar system, with the nucleus at its center, were between 10-7 and 10-8 centimeters. The atom was seen as essentially empty, with a nucleus of enormous relative density at its center. In 1913-14, when the six men I named were still teenagers, a new model ...

... The Standard Model categorises all particles as being matter (fermions) or force carriers (gauge bosons). The gauge bosons are exchange particles that are responsible for the interactions between matter involving three of the four fundamental forces. Describe how exchange particles prevent you from ...

... Taking Thomson’s 1897 paper together with those from 1898 and 1899 gives a very different picture of what he accomplished. As noted, his central concern at the time was with “the connexion between ordinary matter and the electrical charges on the atom.” 11 Electrical phenomena in gases provided his e ...

Chien-Shiung Wu

Chien-Shiung Wu (simplified Chinese: 吴健雄; traditional Chinese: 吳健雄; pinyin: Wú Jiànxióng, 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 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"".
