Dumbbell
The dumbbell, a type of free weight, is a piece of equipment used in weight training. It is usually used individually and/or in pairs, with one in each hand. History The forerunner of the dumbbell, halteres, were used in ancient Greece as lifting weights and also as weights for the ancient Greek version of the long jump. A kind of dumbbell was also used in India for more than a millennium, shaped like a club – so it was named Indian club. The design of the "Meel", as the club was referred to, can be seen as a halfway point between a barbell and a dumbbell. It was generally used in pairs, in workouts by wrestlers, bodybuilders, sports players, and others wishing to increase strength and muscle size. Etymology The term "dumbbell" or "dumb bell" or "dumb-bell" originated in late Stuart England. In 1711 the poet Joseph Addison mentioned exercising with a "dumb bell" in an essay published in ''The Spectator''. Although Addison elsewhere in the same publication describes havin ...

Dumbbells (film)
''Dumbbells'' is a 2014 comedy film directed by Christopher Livingston and starring Brian Drolet, Hoyt Richards, Mircea Monroe, Jaleel White, Taylor Cole, Jay Mohr, Tom Arnold, Laura Ashley Samuels and Andy Milonakis, with a rare film appearance by Nancy Olson (her first film in 17 years). The film saw a limited release on January 10, 2014. The film also marks the film debut of singer Frenchie Davis. The film received generally negative reviews from critics. Synopsis Chris Long is an ex-NCAA basketball player turned trainer who finds a new purpose when his gym's new owner, Jack, unleashes a lucrative plan to turn the neglected business into a reality show. When Chris' co-workers resist this new direction, he and Jack form an unlikely alliance that allows them to face the demons of their pasts and ultimately, save the gym's future. Cast * Brian Drolet as Chris Long * Hoyt Richards as Jack Guy * Jaleel White as The Leader * Mircea Monroe as Kim Hertz * Taylor Cole as Rachel Cor ...

Dumbbell Nebula
The Dumbbell Nebula (also known as the Apple Core Nebula, Messier 27, and NGC 6853) is a planetary nebula (nebulosity surrounding a white dwarf) in the constellation Vulpecula, at a distance of about 1360 light-years. It was the first such nebula to be discovered, by Charles Messier in 1764. At its brightness of visual magnitude 7.5 and diameter of about 8 arcminutes, it is easily visible in binoculars and is a popular observing target in amateur astronomy, amateur telescopes. The Dumbbell Nebula appears shaped like a prolate spheroid and is viewed from our perspective along the plane of its equator. In 1992, Moreno-Corral et al. computed that its rate of expansion angularly was, viewed from our distance, no more than (″) per century. From this, an upper limit to the age of 14,600 years may be determined. In 1970, Bohuski, Smith, and Weedman found an expansion velocity of . Given its semi-minor axis radius of , this implies that the kinematic age of the nebula is 9,800 years. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atomic Orbital
In quantum mechanics, an atomic orbital () is a Function (mathematics), function describing the location and Matter wave, wave-like behavior of an electron in an atom. This function describes an electron's Charge density, charge distribution around the Atomic nucleus, atom's nucleus, and can be used to calculate the probability of finding an electron in a specific region around the nucleus. Each orbital in an atom is characterized by a set of values of three quantum numbers , , and , which respectively correspond to electron's energy, its angular momentum, orbital angular momentum, and its orbital angular momentum projected along a chosen axis (magnetic quantum number). The orbitals with a well-defined magnetic quantum number are generally complex-valued. Real-valued orbitals can be formed as linear combinations of and orbitals, and are often labeled using associated Spherical harmonics#Harmonic polynomial representation, harmonic polynomials (e.g., ''xy'', ) which describe ...

Dumbbell Tenement
Old Law Tenements are tenements built in New York City after the Tenement House Act of 1879 and before the New York State Tenement House Act ("New Law") of 1901. The 1879 law required that every habitable room have a window opening to plain air, a requirement that was met by including air shafts between adjacent buildings. Old Law Tenements are commonly called "dumbbell tenements" after the shape of the building footprint: the air shaft gives each tenement the narrow-waisted shape of a dumbbell, wide facing the street and backyard, narrowed in between to create the air corridor. They were built in great numbers to accommodate waves of immigrating Europeans. The side streets of Manhattan's Lower East Side are still lined with numerous dumbbell structures today. History The 1879 Act was a response to the failure of the Tenement House Act of 1867, which required fire escapes from each suite as well as windows in each room. Builders met the latter part of the 1867 law by merely inse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Interstitial Defect
In materials science, an interstitial defect is a type of point crystallographic defect where an atom of the same or of a different type, occupies an interstitial site in the crystal structure. When the atom is of the same type as those already present they are known as a self-interstitial defect. Alternatively, small atoms in some crystals may occupy interstitial sites, such as hydrogen in palladium. Interstitials can be produced by bombarding a crystal with elementary particles having energy above the displacement threshold for that crystal, but they may also exist in small concentrations in thermodynamic equilibrium. The presence of interstitial defects can modify the physical and chemical properties of a material. History The idea of interstitial compounds was started in the late 1930s and they are often called Hagg phases after Hägg. Transition metals generally crystallise in either the hexagonal close packed or face centered cubic structures, both of which can be conside ...

Dumbell Mountain
Dumbell Mountain is an double summit massif located in the Glacier Peak Wilderness of the North Cascades, in Chelan County of Washington state. The Dumbell summit is slightly higher than the northeast subpeak (8,408 ft) which is unofficially called ''Greenwood Mountain''. The nearest higher neighbor is Chiwawa Mountain, to the east-southeast. Precipitation runoff from Dumbell Mountain drains into tributaries of the Chelan River and the Wenatchee River. The mountain's descriptive name was applied by Albert Hale Sylvester (1871–1944), pioneer surveyor, explorer, topographer, and forest supervisor in the Cascades. Geology Dumbell Mountain is located in the Cloudy Pass batholith, an intrusive formation that was formed approximately , during the early Miocene.Beckey, Fred W.
