Richard F. Casten
Richard Francis Xavier Casten (born November 1, 1941) is an American nuclear physicist. He serves as the D. Allan Bromley Professor Emeritus of Physics at Yale University, where he was also the director of the Wright Nuclear Structure Laboratory from 1995 to 2008. He is known for his research in nuclear structure and radioactive nuclear beams. He is also known for Casten's triangle, which was introduced in 1981. Early life and education Casten was born on November 1, 1941, in New York City. His father was a Jewish surgeon from New York and his mother was a Catholic homemaker. Casten was raised in Manhattan and attended the Quaker Friends Seminary, where he took chemistry classes and decided to pursue physics. Wishing to get out of the city, Casten enrolled at the College of the Holy Cross as a physics major and became a member of its honors program. The college's focus on a liberal arts education allowed him to take courses in history and philosophy, which he later recalled ...

New York City
New York, often called New York City (NYC), is the most populous city in the United States, located at the southern tip of New York State on one of the world's largest natural harbors. The city comprises five boroughs, each coextensive with a respective county. The city is the geographical and demographic center of both the Northeast megalopolis and the New York metropolitan area, the largest metropolitan area in the United States by both population and urban area. New York is a global center of finance and commerce, culture, technology, entertainment and media, academics, and scientific output, the arts and fashion, and, as home to the headquarters of the United Nations, international diplomacy. With an estimated population in 2024 of 8,478,072 distributed over , the city is the most densely populated major city in the United States. New York City has more than double the population of Los Angeles, the nation's second-most populous city. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Friends Seminary
Friends Seminary is an independent K-12 school in Manhattan. The oldest continuously coeducational school in New York City, in recent years it has served approximately 800 students. The school's vision statement declares its purpose is "to prepare students to engage in the world that is and to help bring about a world that ought to be." Robert "Bo" Lauder is principal, the school's 35th. Lauder came to Friends in the fall of 2002 after serving as Upper School Head at Sidwell Friends School in Washington, D.C. History Friends Seminary, established by members of the Religious Society of Friends, whose members are known as Quakers, was founded in 1786 as Friends' Institute through a $10,000 bequest of Robert Murray, a wealthy New York merchant. It was located on Pearl Street in Manhattan and strived to provide Quaker children with a "guarded education." In 1826, the school was moved to a larger campus on Elizabeth Street. Tuition in that year was $10 or less per annum, except f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tandem Accelerator
Tandem, or in tandem, is an arrangement in which two or more animals, machines, or people are lined up one behind another, all facing in the same direction. ''Tandem'' can also be used more generally to refer to any group of persons or objects working together, not necessarily in line. The English word ''tandem'' derives from the Latin adverb , meaning ''at length'' or ''finally''. It is a word play, using the Latin phrase (referring to time, not position) for English "at length, lengthwise". Horse driving When driving horses, ''tandem'' refers to one horse harnessed in front of another to pull a load or vehicle. A tandem arrangement provides more pulling power than a single horse, such as for pulling a heavy load up a steep hill, out of heavy mud or snow, or pulling heavy loads on narrow tracks or through narrow gates and doorways (too wide for a pair of horses side-by-side). For example, a Brewer's van fully loaded with 25 barrels might weigh 8 tons, requiring 2 or 3 hors ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles K
Charles is a masculine given name predominantly found in English and French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man". The Old English descendant of this word was '' Ċearl'' or ''Ċeorl'', as the name of King Cearl of Mercia, that disappeared after the Norman conquest of England. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as ''Karolus'' (as in ''Vita Karoli Magni''), later also as '' Carolus''. Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (James (wikt:Appendix:Proto-Indo-European/ǵerh₂-">ĝer-, where the ĝ is a palatal consonant, meaning "to rub; to be old; grain." An old man has been worn away and is now grey with age. In some Slavic languages, the name ''Drago (given name), Drago'' (and variants: ''Dragom ...

Thesis Defense
A thesis (: theses), or dissertation (abbreviated diss.), is a document submitted in support of candidature for an academic degree or professional qualification presenting the author's research and findings.International Standard International Organization for Standardization, ISO 7144: DocumentationPresentation of theses and similar documents International Organization for Standardization, Geneva, 1986. In some contexts, the word ''thesis'' or a cognate is used for part of a Bachelor's degree, bachelor's or Master's degree, master's course, while ''dissertation'' is normally applied to a doctorate. This is the typical arrangement in American English. In other contexts, such as within most institutions of the United Kingdom, South Africa, the Commonwealth Countries, and Brazil, the reverse is true. The term graduate thesis is sometimes used to refer to both master's theses and doctoral dissertations. The required complexity or quality of research of a thesis or dissertation ...

Doctor Of Philosophy
A Doctor of Philosophy (PhD, DPhil; or ) is a terminal degree that usually denotes the highest level of academic achievement in a given discipline and is awarded following a course of Postgraduate education, graduate study and original research. The name of the degree is most often abbreviated PhD (or, at times, as Ph.D. in North American English, North America), pronounced as three separate letters ( ). The University of Oxford uses the alternative abbreviation "DPhil". PhDs are awarded for programs across the whole breadth of academic fields. Since it is an earned research degree, those studying for a PhD are required to produce original research that expands the boundaries of knowledge, normally in the form of a Thesis, dissertation, and, in some cases, defend their work before a panel of other experts in the field. In many fields, the completion of a PhD is typically required for employment as a university professor, researcher, or scientist. Definition In the context o ...

Master Of Science
A Master of Science (; abbreviated MS, M.S., MSc, M.Sc., SM, S.M., ScM or Sc.M.) is a master's degree. In contrast to the Master of Arts degree, the Master of Science degree is typically granted for studies in sciences, engineering and medicine and is usually for programs that are more focused on scientific and mathematical subjects; however, different universities have different conventions and may also offer the degree for fields typically considered within the humanities and social sciences. While it ultimately depends upon the specific program, earning a Master of Science degree typically includes writing a thesis. The Master of Science degree was introduced at the University of Michigan in 1858. One of the first recipients of the degree was De Volson Wood, who was conferred a Master of Science degree at the University of Michigan in 1859. Algeria Algeria follows the Bologna Process. Australia Australian universities commonly have coursework or research-based Master o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Osmium Isotope
Osmium (76Os) has seven naturally occurring isotopes, five of which are stable: 187Os, 188Os, 189Os, 190Os, and (most abundant) 192Os. The other natural isotopes, 184Os, and 186Os, have extremely long half-life (1.12×1013 years and 2×1015 years, respectively) and for practical purposes can be considered to be stable as well. 187Os is the daughter of 187 Re (half-life 4.12×1010 years) and is most often measured in an 187Os/188Os ratio. This ratio, as well as the 187Re/188Os ratio, have been used extensively in dating terrestrial as well as meteoric rocks. It has also been used to measure the intensity of continental weathering over geologic time and to fix minimum ages for stabilization of the mantle roots of continental cratons. However, the most notable application of Os in dating has been in conjunction with iridium, to analyze the layer of shocked quartz along the Cretaceous–Paleogene boundary that marks the extinction of the dinosaurs 66 million years ago.

Coulomb Excitation
Coulomb excitation is a technique in experimental nuclear physics to probe the electromagnetic aspect of nuclear structure. In Coulomb excitation, a nucleus is excited by an inelastic collision with another nucleus through the electromagnetic interaction. In order to ensure that the interaction is electromagnetic in nature — and not nuclear — the distance of closest approach of the colliding nuclei has to be sufficiently large. In particular, in low-energy Coulomb excitation (taking place at beam energies of a few megaelectronvolts per nucleon) the commonly adopted empirical criterion is that if the surfaces of the colliding nuclei are separated by at least 5 femtometers, the contribution of the short-range nuclear interaction to the excitation process can be neglected. From the measured excitation cross sections, electromagnetic transition probabilities between the nuclear energy levels can be extracted. This method is particularly useful for investigating collectivity in nu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The American Physical Society
The American Physical Society (APS) is a not-for-profit membership organization of professionals in physics and related disciplines, comprising nearly fifty divisions, sections, and other units. Its mission is the advancement and diffusion of knowledge of physics. It publishes more than a dozen scientific journals, including the prestigious ''Physical Review'' and ''Physical Review Letters'', and organizes more than twenty science meetings each year. It is a member society of the American Institute of Physics. Since January 2021, it is led by chief executive officer Jonathan Bagger. History The American Physical Society was founded on May 20, 1899, when thirty-six physicists gathered at Columbia University for that purpose. They proclaimed the mission of the new Society to be "to advance and diffuse the knowledge of physics", and in one way or another the APS has been at that task ever since. In the early years, virtually the sole activity of the APS was to hold scientific meet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magna Cum Laude
Latin honors are a system of Latin phrases used in some colleges and universities to indicate the level of distinction with which an academic degree has been earned. The system is primarily used in the United States. It is also used in some Southeastern Asian countries with European colonial history, such as Indonesia and the Philippines, and African countries such as Zambia and South Africa, although sometimes translations of these phrases are used instead of the Latin originals. The honors distinction should not be confused with the honors degrees offered in some countries, or with honorary degrees. The system usually has three levels of honor (listed in order of increasing merit): ''cum laude'', ''magna cum laude'', and ''summa cum laude''. Generally, a college or university's regulations set out definite criteria a student must meet to obtain a given honor. For example, the student might be required to achieve a specific grade point average, submit an honors thesis for evalu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
