Candela
The candela ( or ; symbol: cd) is the unit of luminous intensity in the International System of Units (SI). It measures luminous power per unit solid angle emitted by a light source in a particular direction. Luminous intensity is analogous to radiant intensity, but instead of simply adding up the contributions of every wavelength of light in the source's spectrum, the contribution of each wavelength is weighted by the standard luminosity function (a model of the sensitivity of the human eye to different wavelengths). A common wax candle emits light with a luminous intensity of roughly one candela. If emission in some directions is blocked by an opaque barrier, the emission would still be approximately one candela in the directions that are not obscured. The word ''candela'' is Latin for ''candle''. The old name "candle" is still sometimes used, as in ''foot-candle'' and the modern definition of ''candlepower''.

Ladies' Home Journal
''Ladies' Home Journal'' was an American magazine last published by the Meredith Corporation. It was first published on February 16, 1883, and eventually became one of the leading women's magazines of the 20th century in the United States. In 1891, it was published in Philadelphia by the Curtis Publishing Company. In 1903, it was the first American magazine to reach one million subscribers. In the late 20th century, changing tastes and competition from television caused it to lose circulation. Sales of the magazine declined as the publishing company struggled. On April 24, 2014, Meredith announced it would stop publishing the magazine as a monthly with the July issue, stating it was "transitioning ''Ladies' Home Journal'' to a special interest publication". It was then available quarterly on newsstands only, though its website remained in operation. The last issue was published in 2016. ''Ladies' Home Journal'' was one of the Seven Sisters, as a group of women's service mag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edison General Electric Company
Thomas Alva Edison (February 11, 1847October 18, 1931) was an American inventor and businessman. He developed many devices in fields such as electric power generation, mass communication, sound recording, and motion pictures. These inventions, which include the phonograph, the motion picture camera, and early versions of the electric light bulb, have had a widespread impact on the modern industrialized world. He was one of the first inventors to apply the principles of organized science and teamwork to the process of invention, working with many researchers and employees. He established the first industrial research laboratory. Edison was raised in the American Midwest. Early in his career he worked as a telegraph operator, which inspired some of his earliest inventions. In 1876, he established his first laboratory facility in Menlo Park, New Jersey, where many of his early inventions were developed. He later established a botanical laboratory in Fort Myers, Florida, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White House
The White House is the official residence and workplace of the president of the United States. It is located at 1600 Pennsylvania Avenue NW in Washington, D.C., and has been the residence of every U.S. president since John Adams in 1800. The term "White House" is often used as a metonym for the president and his advisers. The residence was designed by Irish-born architect James Hoban in the neoclassical style. Hoban modelled the building on Leinster House in Dublin, a building which today houses the Oireachtas, the Irish legislature. Construction took place between 1792 and 1800, using Aquia Creek sandstone painted white. When Thomas Jefferson moved into the house in 1801, he (with architect Benjamin Henry Latrobe) added low colonnades on each wing that concealed stables and storage. In 1814, during the War of 1812, the mansion was set ablaze by British forces in the Burning of Washington, destroying the interior and charring much of the exterior. Reconstr ...

Grover Cleveland
Stephen Grover Cleveland (March 18, 1837June 24, 1908) was an American lawyer and politician who served as the 22nd and 24th president of the United States from 1885 to 1889 and from 1893 to 1897. Cleveland is the only president in American history to serve two non-consecutive terms in office. He won the popular vote for three presidential elections—in 1884, 1888, and 1892—and was one of two Democrats (followed by Woodrow Wilson in 1912) to be elected president during the era of Republican presidential domination dating from 1861 to 1933. In 1881, Cleveland was elected mayor of Buffalo, and in 1882, he was elected governor of New York. He was the leader of the pro-business Bourbon Democrats who opposed high tariffs, free silver, inflation, imperialism, and subsidies to business, farmers, or veterans. His crusade for political reform and fiscal conservatism made him an icon for American conservatives of the era. Cleveland won praise for his honesty, self-relia ...

Murray Hill, Manhattan
Murray Hill is a neighborhood on the east side of Manhattan in New York City. Murray Hill is generally bordered to the east by the East River or Kips Bay and to the west by Midtown Manhattan, though the exact boundaries are disputed. Murray Hill is situated on a steep glacial hill that peaked between Lexington Avenue and Broadway. It was named after Robert Murray, the head of the Murray family, a mercantile family that settled in the area in the 18th century. The Murray farm was formed before 1762 and existed until at least the early 19th century. Through the 19th century, Murray Hill was relatively isolated from the rest of New York City, which at the time was centered in Lower Manhattan. Murray Hill became an upscale neighborhood during the 20th century. Today, it contains several cultural institutions such as the Morgan Library & Museum, as well as missions and consulates to the nearby United Nations headquarters. The neighborhood also contains architectural landmarks, som ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walnut
A walnut is the edible seed of a drupe of any tree of the genus ''Juglans'' (family Juglandaceae), particularly the Persian or English walnut, '' Juglans regia''. Although culinarily considered a "nut" and used as such, it is not a true botanical nut. After full ripening, the shell is discarded and the kernel is eaten. Nuts of the eastern black walnut (''Juglans nigra'') and butternuts ('' Juglans cinerea'') are less commonly consumed. Characteristics Walnuts are rounded, single-seeded stone fruits of the walnut tree commonly used for food after fully ripening between September and November, in which the removal of the husk at this stage reveals a browning wrinkly walnut shell, which is usually commercially found in two segments (three or four-segment shells can also form). During the ripening process, the husk will become brittle and the shell hard. The shell encloses the kernel or meat, which is usually made up of two halves separated by a membranous partition. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elevator
An elevator or lift is a cable-assisted, hydraulic cylinder-assisted, or roller-track assisted machine that vertically transports people or freight between floors, levels, or decks of a building, vessel, or other structure. They are typically powered by electric motors that drive traction cables and counterweight systems such as a hoist, although some pump hydraulic fluid to raise a cylindrical piston like a jack. In agriculture and manufacturing, an elevator is any type of conveyor device used to lift materials in a continuous stream into bins or silos. Several types exist, such as the chain and bucket elevator, grain auger screw conveyor using the principle of Archimedes' screw, or the chain and paddles or forks of hay elevators. Languages other than English, such as Japanese, may refer to elevators by loanwords based on either ''elevator'' or ''lift''. Due to wheelchair access laws, elevators are often a legal requirement in new multistory buildings, espec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
