Herschel Wedge
A Herschel wedge or Herschel prism is an optical prism used in solar observation to refract most of the light out of the optical path, allowing safe visual observation. It was first proposed and used by astronomer John Herschel in the 1830s. Overview The prism in a Herschel wedge has a trapezoidal cross section. The surface of the prism facing the light acts as a standard diagonal mirror, reflecting a small portion of the incoming light at 90 degrees into the eyepiece. The trapezoidal prism shape refracts the remainder of the light gathered by the telescope's objective away at an angle. The Herschel wedge reflects about 4.6% of the light that passes through one of the prism faces that is flat to 1/10 of the wavelength of the light. The remaining ~95.4% of the light and heat goes into the prism and exits through the other face and out the back door of the housing; thus, the excess light and heat is disposed of and not used for observing. While they decrease the intensity of the lig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Herschel Walker Trade
The Herschel Walker trade was the largest player trade in the history of the National Football League (NFL). This deal on October 12, 1989, centered on sending running back Herschel Walker from the Dallas Cowboys to the Minnesota Vikings. Including Walker and a transaction involving the San Diego Chargers, the trade eventually involved 18 players and draft picks. At the time of the deal, the Cowboys were one of the worst teams in the league (the team finished the 1989 season with its worst post-merger record, 1–15), trading away their best player, while the Vikings believed that Walker was the missing piece they needed to make a Super Bowl run. Thus, Minnesota originally felt that they got the better end of the deal. Instead, the Cowboys used the draft picks acquired in this trade to get the players they needed to help them win three Super Bowls in the 1990s. Meanwhile, the Vikings did not make a Super Bowl appearance with Walker. Background In his book, ''Greatest Team Ever: The ...

Herschel Greer Stadium
Herschel Greer Stadium was a Minor League Baseball park in Nashville, Tennessee, on the grounds of Fort Negley, an American Civil War fortification, approximately south of the city's downtown district. The facility closed at the end of the 2014 baseball season and remained deserted for over four years until its demolition in 2019. Following an archaeological survey, the land is expected to be reincorporated into Fort Negley Park. Greer was opened in 1978 for the Nashville Sounds, an expansion franchise of the Double-A Southern League who moved to the Triple-A American Association in 1985 and to the Triple-A Pacific Coast League in 1998. The stadium played host to the team until 2014. The subject of numerous upgrades and repairs to maintain its functionality, Greer became one of the oldest stadiums used by a Triple-A team and had fallen well below professional baseball's standards for a stadium at that class level by the end of its use. For over a decade, the Sounds attempte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herschel Graph
In graph theory, a branch of mathematics, the Herschel graph is a bipartite undirected graph with 11 vertices and 18 edges. It is a polyhedral graph (the graph of a convex polyhedron), and is the smallest polyhedral graph that does not have a Hamiltonian cycle, a cycle passing through all its vertices. It is named after British astronomer Alexander Stewart Herschel, because of Herschel's studies of Hamiltonian cycles in polyhedral graphs (but not of this graph). Definition and properties The Herschel graph has three vertices of degree four and eight vertices of degree three. Each of the three pairs of degree-four vertices form a cycle of four vertices, in which they alternate with two of the degree-three vertices. Each of the two remaining degree-three vertices is adjacent to a degree-three vertex from each of these three cycles. The Herschel graph is a polyhedral graph; this means that it is a planar graph, one that can be drawn in the plane with none of its edges crossing, and ...

Herschel Grammar School
Herschel Grammar School is a co-educational grammar school with academy status, located in Slough, Berkshire, England. The headteacher is Mrs Joanne Rockall. The school has around 900 pupils, 250 of whom are in the sixth form. History The school was established in town centre buildings formerly occupied by Slough Secondary School in William Street (a site later occupied by the Slough campus of Thames Valley University) in about 1952. In 1958, the school moved to a purpose-built site on Northampton Avenue, occupying land that had (before the Second World War) been used as 'Timbertown', an area of temporary houses. The school has remained at Northampton Avenue, although for the 1988/89 academic year it temporarily moved to the site of the former Orchard Secondary Modern School while the permanent buildings were refurbished after damage to the roof in the storms of 1987. Within its present buildings, the school has had a number of names and forms, including: :''Slough Technica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Herschel Baronets
The Herschel Baronetcy, of Slough in the County of Buckingham, was a title in the Baronetage of the United Kingdom. It was created on 17 July 1838 for John Herschel, son of the famous astronomer Sir William Herschel, and a well-known astronomer in his own right.

Herschel–Bulkley Fluid
The Herschel–Bulkley fluid is a generalized model of a non-Newtonian fluid, in which the strain experienced by the fluid is related to the stress in a complicated, non-linear way. Three parameters characterize this relationship: the consistency ''k'', the flow index ''n'', and the yield shear stress \tau_0. The consistency is a simple constant of proportionality, while the flow index measures the degree to which the fluid is shear-thinning or shear-thickening. Ordinary paint is one example of a shear-thinning fluid, while oobleck provides one realization of a shear-thickening fluid. Finally, the yield stress quantifies the amount of stress that the fluid may experience before it yields and begins to flow. This non-Newtonian fluid model was introduced by Winslow Herschel and Ronald Bulkley in 1926. Definition In one dimension, the constitutive equation of the Herschel-Bulkley model after the yield stress has been reached can be written in the form: :\dot = 0, \qquad\qquad \ ...

Allan Herschell Company
The Allan Herschell Company specialized in the creation of amusement rides, particularly carousels and roller coasters. The company manufactured portable machines that could be used by traveling carnival operators. It was started in 1915 in the town of North Tonawanda, just outside Buffalo, New York, USA. History Previous companies Herschell, with James Armitage, created the Armitage Herschell Company in 1873. In 1883, his son William traveled to London to meet former Limonaire Frères employee Eugene de Kleist. Backed by Armitage Herschell, in 1888, de Kleist set up band-organ production in North Tonawanda, founding the North Tonawanda Barrel Organ Factory. The company produced a range of barrel-organ based products, suited for all ranges of fairground attraction. Armitage Herschell remained in operation until the early 1900s. The company carved many portable carousels, made simple in style. Surviving steam riding galleries are located in Mississippi and Maine. In 1901, Hersche ...

Uranus
Uranus is the seventh planet from the Sun. Its name is a reference to the Greek god of the sky, Uranus (mythology), Uranus (Caelus), who, according to Greek mythology, was the great-grandfather of Ares (Mars (mythology), Mars), grandfather of Zeus (Jupiter (mythology), Jupiter) and father of Cronus (Saturn (mythology), Saturn). It has the third-largest planetary radius and fourth-largest planetary mass in the Solar System. Uranus is similar in composition to Neptune, and both have bulk chemical compositions which differ from that of the larger gas giants Jupiter and Saturn. For this reason, scientists often classify Uranus and Neptune as "ice giants" to distinguish them from the other giant planets. As with gas giants, ice giants also lack a well defined "solid surface." Uranus's Atmosphere#Others, atmosphere is similar to Jupiter's and Saturn's in its primary composition of hydrogen and helium, but it contains more "volatiles, ices" such as water, ammonia, and methane, al ...
