Lise Meitner
Elise Meitner ( , ; 7 November 1878 – 27 October 1968) was an Austrian-Swedish physicist who was one of those responsible for the discovery of the element protactinium and nuclear fission. While working at the Kaiser Wilhelm Institute on radioactivity, she discovered the radioactive isotope protactinium-231 in 1917. In 1938, Meitner and her nephew, the physicist Otto Robert Frisch, discovered nuclear fission. She was praised by Albert Einstein as the "German Marie Curie". Completing her doctoral research in 1905, Meitner became the second woman from the University of Vienna to earn a doctorate in physics. She spent most of her scientific career in Berlin, Germany, where she was a physics professor and a department head at the Kaiser Wilhelm Institute; she was the first woman to become a full professor of physics in Germany. She lost these positions in the 1930s because of the anti-Jewish Nuremberg Laws of Nazi Germany, and in 1938 she fled to Sweden, where she lived for many ...

Otto Hahn
Otto Hahn (; 8 March 1879 – 28 July 1968) was a German chemist who was a pioneer in the fields of radioactivity and radiochemistry. He is referred to as the father of nuclear chemistry and father of nuclear fission. Hahn and Lise Meitner discovered radioactive isotopes of radium, thorium, protactinium and uranium. He also discovered the phenomena of atomic recoil and nuclear isomerism, and pioneered rubidium–strontium dating. In 1938, Hahn, Lise Meitner and Fritz Strassmann discovered nuclear fission, for which Hahn received the 1944 Nobel Prize for Chemistry. Nuclear fission was the basis for nuclear reactors and nuclear weapons. A graduate of the University of Marburg, Hahn studied under Sir William Ramsay at University College London and at McGill University in Montreal under Ernest Rutherford, where he discovered several new radioactive isotopes. He returned to Germany in 1906; Emil Fischer placed a former woodworking shop in the basement of the Chemical Institute ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Fission
Nuclear fission is a reaction in which the nucleus of an atom splits into two or more smaller nuclei. The fission process often produces gamma photons, and releases a very large amount of energy even by the energetic standards of radioactive decay. Nuclear fission of heavy elements was discovered on Monday 19 December 1938, by German chemist Otto Hahn and his assistant Fritz Strassmann in cooperation with Austrian-Swedish physicist Lise Meitner. Hahn understood that a "burst" of the atomic nuclei had occurred. Meitner explained it theoretically in January 1939 along with her nephew Otto Robert Frisch. Frisch named the process by analogy with biological fission of living cells. For heavy nuclides, it is an exothermic reaction which can release large amounts of energy both as electromagnetic radiation and as kinetic energy of the fragments (heating the bulk material where fission takes place). Like nuclear fusion, for fission to produce energy, the total binding energy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sacramento City College
Sacramento City College (SCC) is a public community college in Sacramento, California. SCC is part of the Los Rios Community College District and had an enrollment of 25,307 in 2009. It is accredited by the Accrediting Commission for Community and Junior Colleges (ACCJC), offering Associate in Science (A.S) and Associate in Art (A.A.) degrees. History Founded in 1916 as a department of Sacramento High School, Sacramento City College is the seventh oldest public community college in California and the oldest institution of higher learning in Sacramento. Rare for its time, Sacramento City College was founded by a woman (Belle Cooledge) and with an all female class as its first graduates, the college began with the spirit of inclusion at its very heart. First known as Sacramento Junior College, Cooledge founded the college to provide a safe, welcoming place for students to learn the basics for a college education, and to be a gathering spot for extra-curricular activities that wou ...

Barnard College
Barnard College of Columbia University is a private women's liberal arts college in the borough of Manhattan in New York City. It was founded in 1889 by a group of women led by young student activist Annie Nathan Meyer, who petitioned Columbia University's trustees to create an affiliated college named after Columbia's recently deceased 10th president, Frederick A.P. Barnard. Barnard College was one of more than 120 women's colleges founded in the 19th century, and one of fewer than 40 in existence today solely dedicated to the academic empowerment of women. The acceptance rate of the Class of 2025 was 11.4% and marked the most selective and diverse class in the college's 133-year history, with 66% of incoming U.S. students self-identifying as women of color. Barnard is one of Columbia University's four undergraduate colleges. Founded as a response to Columbia's refusal to admit women into their institution until 1983, Barnard is affiliated with but legally and financially sep ...

Harvard University
Harvard University is a private Ivy League research university in Cambridge, Massachusetts. Founded in 1636 as Harvard College and named for its first benefactor, the Puritan clergyman John Harvard, it is the oldest institution of higher learning in the United States and one of the most prestigious and highly ranked universities in the world. The university is composed of ten academic faculties plus Harvard Radcliffe Institute. The Faculty of Arts and Sciences offers study in a wide range of undergraduate and graduate academic disciplines, and other faculties offer only graduate degrees, including professional degrees. Harvard has three main campuses: the Cambridge campus centered on Harvard Yard; an adjoining campus immediately across Charles River in the Allston neighborhood of Boston; and the medical campus in Boston's Longwood Medical Area. Harvard's endowment is valued at $50.9 billion, making it the wealthiest academic institution in the world. Endowment inco ...

Barnard College Alumni
Barnard is a version of the surname Bernard, which is a French and West Germanic masculine given name and surname. The surname means as tough as a bear, Bar(Bear)+nard/hard(hardy/tough) __NOTOC__ People Some of the people bearing the surname Barnard in England are thought to have arrived after the time of the Norman Conquest (1066), Changing their surnames from Bernard to Barnard. Some of whom, it has been suggested, can be traced back to Hugo Bernard. Some of the Barnard family in England may have been Huguenots who fled from the Atlantic coast region of France ''circa'' 1685 (the time of the revocation of the edict of Nantes) or earlier than that date. By contrast, the Barnard family in Holland (the western provinces of the Netherlands) can be definitively traced back to ''circa'' 1751 (Izaak Barnard) of Scheveningen.The surname Barnard is also found in South Africa among the Afrikaner community. An example of this is Christiaan Barnard, A South African Cardiac Surgeon who p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
