Mass
Mass is an intrinsic property of a body. It was traditionally believed to be related to the quantity of matter in a physical body, until the discovery of the atom and particle physics. It was found that different atoms and different elementary particles, theoretically with the same amount of matter, have nonetheless different masses. Mass in modern physics has multiple definitions which are conceptually distinct, but physically equivalent. Mass can be experimentally defined as a measure of the body's inertia, meaning the resistance to acceleration (change of velocity) when a net force is applied. The object's mass also determines the strength of its gravitational attraction to other bodies. The SI base unit of mass is the kilogram (kg). In physics, mass is not the same as weight, even though mass is often determined by measuring the object's weight using a spring scale, rather than balance scale comparing it directly with known masses. An object on the Moon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Institute Of Astronomy, Cambridge
The Institute of Astronomy (IoA) is the largest of the three astronomy departments in the University of Cambridge, and one of the largest astronomy sites in the United Kingdom. Around 180 academics, postdocs, visitors and assistant staff work at the department. Research at the department is made in a number of scientific areas, including exoplanets, stars, star clusters, cosmology, gravitational-wave astronomy, the high-redshift universe, AGN, galaxies and galaxy clusters. This is a mixture of observational astronomy, over the entire electromagnetic spectrum, computational theoretical astronomy, and analytic theoretical research. The Kavli Institute for Cosmology is also located on the department site. This institute has an emphasis on ''The Universe at High Redshifts''. The Cavendish Astrophysics Group are based in the Battcock Centre, a building in the same grounds. History The institute was formed in 1972 from the amalgamation of earlier institutions: * The Universi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plumian Professor Of Astronomy And Experimental Philosophy
The Plumian chair of Astronomy and Experimental Philosophy is one of the major professorships in Astronomy at Cambridge University, alongside the Lowndean Professorship (which is now mainly held by mathematicians). The chair is currently held at the Institute of Astronomy in the University. The Plumian chair was founded in 1704 by Thomas Plume, a member of Christ's and Archdeacon of Rochester, to "erect an Observatory and to maintain a studious and learned Professor of Astronomy and Experimental Philosophy, and to buy him and his successors utensils and instruments quadrants telescopes etc." Trustees were appointed, and statutes drawn up by Isaac Newton, John Flamsteed and John Ellys. The first Professorship was awarded in 1706 to Roger Cotes, a former student of Newton, and the stipend was increased in 1768 by Dr Robert Smith, the second Plumian Professor.

Provost (education)
A provost is a senior academic administrator. At many institutions of higher education, they are the chief academic officer, a role that may be combined with being deputy to the chief executive officer. They may also be the chief executive officer of a university, of a branch campus of a university, or of a college within a university. Duties, role, and selection The specific duties and areas of responsibility for a provost vary from one institution to another, but usually include supervision and oversight of curricular, instructional, and research affairs. The various deans of a university's schools, colleges, or faculties typically report to the provost, or jointly to them and the institution's chief executive officer—which office may be called president, chancellor, vice-chancellor or rector. Likewise do the heads of the various interdisciplinary units and academic support functions (such as libraries, student services, the registrar, admissions, and information techn ...

University Administrator
Academic administration is a branch of university or college employees responsible for the maintenance and supervision of the institution and separate from the faculty or academics, although some personnel may have joint responsibilities. Some type of separate administrative structure exists at almost all academic institutions. Fewer institutions are governed by employees who are also involved in academic or scholarly work. Many senior administrators are academics who have advanced degrees and no longer teach or conduct research. Key responsibilities Key broad administrative responsibilities (and thus administrative units) in academic institutions include: * Admissions * Supervision of academic affairs such as hiring, promotion, tenure, and evaluation (with faculty input where appropriate); * Maintenance of official records (typically supervised by a registrar); * Maintenance and audit of financial flows and records; * Maintenance and construction of campus buildings and grounds ...

Scientific American
''Scientific American'', informally abbreviated ''SciAm'' or sometimes ''SA'', is an American popular science magazine. Many famous scientists, including Albert Einstein and Nikola Tesla, have contributed articles to it. In print since 1845, it is the oldest continuously published magazine in the United States. ''Scientific American'' is owned by Springer Nature, which in turn is a subsidiary of Holtzbrinck Publishing Group. History ''Scientific American'' was founded by inventor and publisher Rufus Porter in 1845 as a four-page weekly newspaper. The first issue of the large format newspaper was released August 28, 1845. Throughout its early years, much emphasis was placed on reports of what was going on at the U.S. Patent Office. It also reported on a broad range of inventions including perpetual motion machines, an 1860 device for buoying vessels by Abraham Lincoln, and the universal joint which now can be found in nearly every automobile manufactured.

Astronomy
Astronomy () is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Babylonians, Greeks, Indians, Egyptians, Chinese, Maya, and many ancient indigenous peoples of the Americas. In the past, astronomy included disciplines as diverse as astrometry, celestial navigation, observational astronomy, and the making of calend ...

Professor
Professor (commonly abbreviated as Prof.) is an academic rank at universities and other post-secondary education and research institutions in most countries. Literally, ''professor'' derives from Latin as a "person who professes". Professors are usually experts in their field and teachers of the highest rank. In most systems of academic ranks, "professor" as an unqualified title refers only to the most senior academic position, sometimes informally known as "full professor". In some countries and institutions, the word "professor" is also used in titles of lower ranks such as associate professor and assistant professor; this is particularly the case in the United States, where the unqualified word is also used colloquially to refer to associate and assistant professors as well. This usage would be considered incorrect among other academic communities. However, the otherwise unqualified title "Professor" designated with a capital letter nearly always refers to a full pro ...
