Leon Cooper
Leon N. Cooper (né Kupchik; February 28, 1930 – October 23, 2024) was an American theoretical physicist and neuroscientist. He won the Nobel Prize in Physics for his work on superconductivity. Cooper developed the concept of Cooper pairs and collaborated with John Bardeen and John Robert Schrieffer to develop the BCS theory of conventional superconductivity. In neuroscience, Cooper co-developed the BCM theory of synaptic plasticity. Biography Childhood and education Leon N. Kupchick was born in the Bronx, New York City on February 28, 1930. His middle initial N. does not stand for anything, though some sources erroneously suggested his middle name was Neil. His father Irving Kupchik was from Belarus and moved to the United States after the Russian Revolution in 1917. His mother Anna (née Zola) Kupchik was from Poland; she died when Leon was seven. His father later changed the family's surname from Kupchick to Cooper when he remarried. Leon attended the Bronx High S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Conventional Superconductivity
Conventional superconductors are materials that display superconductivity as described by BCS theory or its extensions. This is in contrast to unconventional superconductors, which do not. Conventional superconductors can be either type-I or type-II. Most elemental superconductors are conventional. Niobium and vanadium are type-II, while most other elemental superconductors are type-I. Critical temperatures of some elemental superconductors: Most compound and alloy superconductors are type-II materials. The most commonly used conventional superconductor in applications is a niobium-titanium alloy - this is a type-II superconductor with a superconducting critical temperature of 11 K. The highest critical temperature so far achieved in a conventional superconductor was 39 K (-234 °C) in magnesium diboride Magnesium diboride is the inorganic compound of magnesium and boron with the formula MgB2. It is a dark gray, water-insoluble solid. The compound becomes superconducting at 3 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Master Of Arts
A Master of Arts ( or ''Artium Magister''; abbreviated MA or AM) is the holder of a master's degree awarded by universities in many countries. The degree is usually contrasted with that of Master of Science. Those admitted to the degree have typically studied subjects within the scope of the humanities and social sciences, such as history, literature, languages, linguistics, public administration, political science, communication studies, law or diplomacy; however, different universities have different conventions and may also offer the degree for fields typically considered within the natural sciences and mathematics. The degree can be conferred in respect of completing courses and passing examinations, research, or a combination of the two. The degree of Master of Arts traces its origins to the teaching license or of the University of Paris, designed to produce "masters" who were graduate teachers of their subjects.

Graduate School
Postgraduate education, graduate education, or graduate school consists of academic or professional degrees, certificates, diplomas, or other qualifications usually pursued by post-secondary students who have earned an undergraduate (bachelor's) degree. The organization and structure of postgraduate education varies in different countries, as well as in different institutions within countries. The term "graduate school" or "grad school" is typically used in North America, while "postgraduate" is more common in the rest of the English-speaking world. Graduate degrees can include master's and doctoral degrees, and other qualifications such as graduate diplomas, certificates and professional degrees. A distinction is typically made between graduate schools (where courses of study vary in the degree to which they provide training for a particular profession) and professional schools, which can include medical school, law school, business school, and other institutions of ...

Surname
In many societies, a surname, family name, or last name is the mostly hereditary portion of one's personal name that indicates one's family. It is typically combined with a given name to form the full name of a person, although several given names and surnames are possible in the full name. In modern times most surnames are hereditary, although in most countries a person has a right to name change, change their name. Depending on culture, the surname may be placed either at the start of a person's name, or at the end. The number of surnames given to an individual also varies: in most cases it is just one, but in Portuguese-speaking countries and many Spanish-speaking countries, two surnames (one inherited from the mother and another from the father) are used for legal purposes. Depending on culture, not all members of a family unit are required to have identical surnames. In some countries, surnames are modified depending on gender and family membership status of a person.

Middle Name
In various cultures, a middle name is a portion of a personal name that is written between a person's given name and surname. A middle name is often abbreviated and is then called middle initial or just initial. A person may be given a middle name regardless of whether it is necessary to distinguish them from other people with the same given name and surname. In cultures where a given name is expected to precede the surname, additional names are likely to be placed after the given name and before the surname, and thus called middle names. Usage in English Among royalty and aristocracy, middle names have been used since the late 17th century (and possibly earlier), as exemplified in the name of the Stuart pretender James Francis Edward Stuart (1688–1766). Despite their relatively long existence in North America, the term ''middle name'' was not recorded until 1835, in the periodical '' Harvardiana''. Not every name that stands as the middle word in a three-name string is a mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
