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 li ... [...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). The deal, completed on October 12, 1989, centered on sending running back Herschel Walker from the Dallas Cowboys to the Minnesota Vikings. After the transaction was expanded to involve the San Diego Chargers, the trade moved a total of 18 players and draft picks between the three teams. 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) while Walker was still regarded as one of the league's premier running backs. In a surprise move, the Cowboys chose to waive, cut, or trade all the players acquired from the Vikings. The Vikings had offered draft compensation for any player who was not on the Cowboys' roster by February 1st, 1990. Coach Jimmy Johnson, also in charge of roster management, had intended throughout the trade to cut all acquired players and take the dra ...

Herschel The Sea Lion
Herschel the sea lion was the moniker given to a series of male California sea lions in Seattle, Washington, United States. Herschel took up seasonal residence in the early to mid-1980s on the saltwater side of Seattle's Salmon Bay at the Ballard Locks where salmon runs were funneled into the fish ladder. Due to the volume of fish the groups would consume, attempts at deterring or removing Herschel and other young males became a yearly process that gained national media attention. Name origin and fame One story for the origin of the epithet "Herschel" is that when the first sea lion was spotted near the Hiram M. Chittenden Locks, Ballard Locks, a fisherman called out "Oh hey, that looks like old Herschel that I used to work with down at the docks". The original Herschel the sea lion was estimated to weigh between and was one of the largest in his group of young males. It is thought that the original returned for several years in the early 1980s only, and from the mid-1980s t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herschel Greer Stadium
Herschel Greer Stadium was a Minor League Baseball baseball park, 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 (baseball), Double-A Southern League (1964–present), Southern League who moved to the Triple-A (baseball), Triple-A American Association (1902–1997), 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 profess ...

Herschel Graph
In graph theory, a branch of mathematics, the Herschel graph is a bipartite graph, 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 (the three blue vertices aligned vertically in the center of the illustration) and eight vertices of degree three. Each two distinct degree-four vertices share two degree-three neighbors, forming a four-vertex cycle with these shared neighbors. There are three of these cycles, passing through six of the eight degree-three vertices (red in the illustration). Two more degree-three vertices (blue) do not participate in these four- ...

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\qqu ...

Allan Herschell Company
The Allan Herschell Company was a company that 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, United States. History Armitage–Herschell Company Scottish immigrant Allan Herschell, with James Armitage, created the Armitage–Herschell Company in 1872. Originally an iron foundry, it branched out into hand-carved wooden carousels in 1883. That same year, Herschell's 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 carved many portable ...

Uranus
Uranus is the seventh planet from the Sun. It is a gaseous cyan-coloured ice giant. Most of the planet is made of water, ammonia, and methane in a Supercritical fluid, supercritical phase of matter, which astronomy calls "ice" or Volatile (astrogeology), volatiles. Atmosphere of Uranus, The planet's atmosphere has a complex layered cloud structure and has the lowest minimum temperature () of all the Solar System's planets. It has a marked axial tilt of 82.23° with a Retrograde and prograde motion, retrograde rotation period of 17 hours and 14 minutes. This means that in an 84-Earth-year orbital period around the Sun, its poles get around 42 years of continuous sunlight, followed by 42 years of continuous darkness. Uranus has the third-largest diameter and fourth-largest mass among the Solar System's planets. Based on current models, inside its volatile Mantle (geology), mantle layer is a rocky core, and surrounding it is a thick hydrogen and helium atmosphere. Trace amount ...
