Geiger (crater)
Geiger is a lunar impact crater on the far side of the Moon. It lies to the southwest of the much larger walled plain Keeler, and slightly farther to the northeast of the huge walled plain Gagarin. To the south is the crater Cyrano Cyrano may refer to: Astronomy * 3582 Cyrano, a small main belt asteroid * Cyrano (crater), a lunar impact crater that lies on the far side of the Moon Stage and film * ''Cyrano'' (Damrosch), a 1913 opera by Walter Damrosch * ''Cyrano'', a 195 .... This is a not-quite symmetrical crater formation with small outward bulges along the north and northeast. The rim to the southeast is less well-formed than elsewhere. The northern inner wall is more extensive than elsewhere, slumping across about one-third the inner floor. The interior is otherwise relatively level and is marked by a few tiny craterlets. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest t ...

Geiger Counter
A Geiger counter (also known as a Geiger–Müller counter) is an electronic instrument used for detecting and measuring ionizing radiation. It is widely used in applications such as radiation dosimetry, radiological protection, experimental physics, nuclear industry and the Manumouthry. It detects ionizing radiation such as alpha particles, beta particles, and gamma rays using the ionization effect produced in a Geiger–Müller tube, which gives its name to the instrument. In wide and prominent use as a hand-held radiation survey instrument, it is perhaps one of the world's best-known radiation detection instruments. The original detection principle was realized in 1908 at the University of Manchester, but it was not until the development of the Geiger–Müller tube in 1928 that the Geiger counter could be produced as a practical instrument. Since then, it has been very popular due to its robust sensing element and relatively low cost. However, there are limitations in ...

Geiger–Müller Tube
The Geiger–Müller tube or G–M tube is the sensing element of the Geiger counter instrument used for the detection of ionizing radiation. It is named after Hans Geiger, who invented the principle in 1908, and Walther Müller, who collaborated with Geiger in developing the technique further in 1928 to produce a practical tube that could detect a number of different radiation types. It is a gaseous ionization detector and uses the Townsend avalanche phenomenon to produce an easily detectable electronic pulse from as little as a single ionizing event due to a radiation particle. It is used for the detection of gamma radiation, X-rays, and alpha and beta particles. It can also be adapted to detect neutrons. The tube operates in the "Geiger" region of ion pair generation. This is shown on the accompanying plot for gaseous detectors showing ion current against applied voltage. While it is a robust and inexpensive detector, the G–M is unable to measure high radiation rates efficient ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geiger–Nuttall Law
In nuclear physics, the Geiger–Nuttall law or Geiger–Nuttall rule relates the decay constant of a radioactive isotope with the energy of the alpha particles emitted. Roughly speaking, it states that short-lived isotopes emit more energetic alpha particles than long-lived ones. The relationship also shows that half-lives are exponentially dependent on decay energy, so that very large changes in half-life make comparatively small differences in decay energy, and thus alpha particle energy. In practice, this means that alpha particles from all alpha-emitting isotopes across many orders of magnitude of difference in half-life, all nevertheless have about the same decay energy. Formulated in 1911 by Hans Geiger and John Mitchell Nuttall as a relation between the decay constant and the range of alpha particles in air, in its modern form the Geiger–Nuttall law is :\log_\lambda=-a_1\frac+a_2 where ''λ'' is the decay constant (λ = ln2/half-life), ''Z'' the atomic number, ''E'' th ...

Geiger Tree
''Cordia sebestena'' is a shrubby tree in the borage family, Boraginaceae, native to the American tropics. It ranges from southern Florida in the United States and the Bahamas, southwards throughout Central America and the Greater Antilles. Common names have included siricote or kopté (Mayan) in 19th Century northern Yucatán, scarlet cordia in Jamaica, and Geiger tree (after Key West wrecker John Geiger) in Florida. Description ''Cordia sebestena'' grows to a maximum height of at maturity, with a nearly equal spread. The crown is round to vase-shaped. Branches tend to be somewhat drooping, and the tree is naturally multitrunked. When only a single trunk is allowed to develop, it can attain a diameter of . The dense, evergreen foliage consists of dark green, leathery, alternate, ovate leaves, long, with wavy margins. These leaves are covered with small hairs, lending them a rough, "sandpapery" texture. Flowers are produced in clusters at branch ends throughout the year, pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geiger (corporation)
Geiger is an advertising specialties company with more than 500 employees and more than 550 sales representatives. It is the industry's largest family-owned and family-managed distributorship and is based in Lewiston, Maine. Initially named Geiger Brothers, it was founded in Newark, New Jersey in 1878 and spans 5 generations. History The company was founded when brothers Andrew and Jacob Geiger took over their father’s two-room print shop in Newark, New Jersey. A staff of 4 -- the brothers, a printer, and a bookkeeper—produced a small line that included advertising calendars, fans, and greeting cards. The second generation brothers, Frank, Charles, and George entered the company in the early 20th century. They added date books and diaries to their expanding line. Frank’s two sons, Ray and Frank, joined the business in the 1930s. Frank led the firm into the distribution of advertising specialty products made by other companies. Ray acquired the renowned ''Farmers’ Almana ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geiger (comics)
''Avengers: The Initiative'' is a comic book series from Marvel Comics. Written by Dan Slott and Christos Gage with artwork initially by Stefano Caselli, Steve Uy and Harvey Tolibao, the series deals with the aftermath of Marvel's "Civil War" storyline (however, it should not be confused with "The Initiative" a banner running across Marvel books from Feb. 2007 to May 2007, similar to Marvel's earlier "Decimation" banner after the "House of M" storyline, or the '' Civil War: The Initiative'' special by Brian Michael Bendis). A preview of the title was shown in ''Civil War: The Initiative''. Publication history The first issue of ''Avengers: The Initiative'' was released on 4 April 2007. The tagline initially used in solicitations was "Marvel's Army of Super Heroes just became a Super Hero Army". The series was originally solicited as a six issue limited series, but prior to the publication of the first issue, Marvel announced that this had changed and that ''Avengers: The Init ...
