John E. Geake
John Edward Geake (22 April 1925 – 3 June 1998) was a British astronomer, noted as a lunar scientist, and scientific instrument designer. Career His postgraduate studies at UMIST related to the study of astronomical spectra using a photoelectric photometer. His work parallelled that of Hiltner (1914–1991) and his group in U.S.A.; although at the time, neither knew of the other's work, and their methods were different. This research (which was long before the days of space exploration) led to laboratory measurement of luminescence from meteorite samples, which could be compared with lunar luminescence in an attempt to determine the composition of the lunar surface. His expertise was recognised by both the American and the Soviet space agencies, both of whom allocated to him lunar samples for study. He was a NASA principal investigator, and an editor of ''Lunar Science Conference Proceedings''. One of his interests was in trying to gain information from the polar ...

Solar System
The Solar SystemCapitalization of the name varies. The International Astronomical Union, the authoritative body regarding astronomical nomenclature, specifies capitalizing the names of all individual astronomical objects but uses mixed "Solar System" and "solar system" structures in theinaming guidelines document. The name is commonly rendered in lower case ('solar system'), as, for example, in the ''Oxford English Dictionary'' an''Merriam-Webster's 11th Collegiate Dictionary''. is the gravity, gravitationally bound system of the Sun and the objects that orbit it. It Formation and evolution of the Solar System, formed 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud. The solar mass, vast majority (99.86%) of the system's mass is in the Sun, with most of the Jupiter mass, remaining mass contained in the planet Jupiter. The four inner Solar System, inner system planets—Mercury (planet), Mercury, Venus, Earth and Mars—are terrest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
9298 Geake
9298 Geake, provisional designation , is a Mitidika asteroid from the central regions of the asteroid belt, approximately 12 kilometers in diameter. It was discovered on 15 May 1985, by American astronomer Edward Bowell at Lowell Observatory's Anderson Mesa Station near Flagstaff, Arizona, United States. The asteroid was named for British astronomer John E. Geake. Orbit and classification ''Geake'' has been identified as a member of the Mitidika family, a dispersed asteroid family of carbonaceous C-type asteroids. The family is named after 2262 Mitidika (diameter of 9 km) and consists of 653 known members, the largest ones being 404 Arsinoë (95 km) and 5079 Brubeck (17 km). The asteroid orbits the Sun in the central main-belt at a distance of 1.8–3.3 AU once every 4 years and 2 months (1,507 days). Its orbit has an eccentricity of 0.30 and an inclination of 12 ° with respect to the ecliptic. It was first observed on a precove ...

Main-belt
The asteroid belt is a torus-shaped region in the Solar System, located roughly between the orbits of the planets Jupiter and Mars. It contains a great many solid, irregularly shaped bodies, of many sizes, but much smaller than planets, called asteroids or minor planets. This asteroid belt is also called the main asteroid belt or main belt to distinguish it from other asteroid populations in the Solar System such as near-Earth asteroids and trojan asteroids. The asteroid belt is the smallest and innermost known circumstellar disc in the Solar System. About 60% of its mass is contained in the four largest asteroids: Ceres, Vesta, Pallas, and Hygiea. The total mass of the asteroid belt is calculated to be 3% that of the Moon. Ceres, the only object in the asteroid belt large enough to be a dwarf planet, is about 950 km in diameter, whereas Vesta, Pallas, and Hygiea have mean diameters less than 600 km. The remaining bodies range down to the size of a dust particle. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Strangeways Prison
HM Prison Manchester is a Category A and B men's prison in Manchester, England, operated by His Majesty's Prison Service. It is still commonly referred to as Strangeways, which was its former official name derived from the area in which it is located, until it was rebuilt following a major riot in 1990. It is a local prison, holding prisoners remanded into custody from courts in the Manchester area and Category A prisoners (those held under maximum security conditions). The prison featured an execution chamber prior to the abolition of capital punishment in the United Kingdom in the 1960s; the last execution at the prison took place in 1964. Strangeways was designed by Alfred Waterhouse and opened in 1868 alongside the demolished Manchester Assize Courts. The prison is known for its prominent ventilation tower and imposing design, structured by the principles of the separate system. History Construction of the Grade II listed prison was completed in 1869, and it was open ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Christian Scientist
Christian Science is a set of beliefs and practices associated with members of the Church of Christ, Scientist. Adherents are commonly known as Christian Scientists or students of Christian Science, and the church is sometimes informally known as the Christian Science church. It was founded in 19th-century New England by Mary Baker Eddy, who wrote the 1875 book '' Science and Health with Key to the Scriptures'', which outlined the theology of Christian Science. The book became Christian Science's central text, along with the Bible, and by 2001 had sold over nine million copies. Eddy and 26 followers were granted a charter by the Commonwealth of Massachusetts in 1879 to found the "Church of Christ (Scientist)"; the church would be reorganized under the name " Church of Christ, Scientist" in 1892. The Mother Church, The First Church of Christ, Scientist, was built in Boston, Massachusetts, in 1894. Christian Science became the fastest growing religion in the United States, with ...

Reader (academic Rank)
The title of reader in the United Kingdom and some universities in the Commonwealth of Nations, for example India, Australia and New Zealand, denotes an appointment for a senior academic with a distinguished international reputation in research or scholarship. In the traditional hierarchy of British and other Commonwealth universities, reader (and principal lecturer in the new universities) are academic ranks above senior lecturer and below professor, recognising a distinguished record of original research. Reader is similar to a professor without a chair, similar to the distinction between ''professor extraordinarius'' and ''professor ordinarius'' at some European universities, professor and chaired professor in Hong Kong and "professor name" (or associate professor) and chaired professor in Ireland. Readers and professors in the UK would correspond to full professors in the United States.Graham WebbMaking the most of appraisal: career and professional development planning for le ...

Titan (moon)
Titan is the largest moon of Saturn and the second-largest natural satellite in the Solar System. It is the only moon known to have a dense atmosphere, and is the only known object in space other than Earth on which clear evidence of stable bodies of surface liquid has been found. Titan is one of the seven gravitationally rounded moons in orbit around Saturn, and the second most distant from Saturn of those seven. Frequently described as a planet-like moon, Titan is 50% larger (in diameter) than Earth's Moon and 80% more massive. It is the second-largest moon in the Solar System after Jupiter's moon Ganymede, and is larger than the planet Mercury, but only 40% as massive. Discovered in 1655 by the Dutch astronomer Christiaan Huygens, Titan was the first known moon of Saturn, and the sixth known planetary satellite (after Earth's moon and the four Galilean moons of Jupiter). Titan orbits Saturn at 20 Saturn radii. From Titan's surface, Saturn subtends an arc of 5.09 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cassini–Huygens
''Cassini–Huygens'' ( ), commonly called ''Cassini'', was a space research, space-research mission by NASA, the European Space Agency (ESA), and the Italian Space Agency (ASI) to send a space probe to study the planet Saturn and its system, including its Rings of Saturn, rings and Moons of Saturn, natural satellites. The Large Strategic Science Missions, Flagship-class robotic spacecraft comprised both NASA's ''Cassini'' space probe and ESA's Huygens (spacecraft), ''Huygens'' lander (spacecraft), lander, which landed on Saturn's largest moon, Titan (moon), Titan. ''Cassini'' was the fourth space probe to visit Saturn and the first to enter its orbit, where it stayed from 2004 to 2017. The two craft took their names from the astronomers Giovanni Domenico Cassini, Giovanni Cassini and Christiaan Huygens. Launched aboard a Titan IV, Titan IVB/Centaur on October 15, 1997, ''Cassini'' was active in space for nearly 20 years, with 13 years spent orbiting Saturn and studying the pla ...

Adjunct Professor
An adjunct professor is a type of academic appointment in higher education who does not work at the establishment full-time. The terms of this appointment and the job security of the tenure vary in different parts of the world, however the general definition is agreed upon. The term "Adjuncting" is a way of referring to a bona-fide part-time faculty member who has worked in an adjunct position for an institution of higher education. Terminology They may also be called an adjunct lecturer, adjunct instructor, or adjunct faculty. Collectively, they may be referred to as contingent academic labor. The rank of sessional lecturer in Canadian universities is similar to the US concept. North America In the United States, an adjunct is, in most cases, a non-tenure-track faculty member. However, it can also be a scholar or teacher whose primary employer is not the school or department with which they have adjunct status. Adjunct professors make up the majority of instructors in high ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
