Neon Sign
In the signage industry, neon signs are electric signs lighted by long luminous gas-discharge tubes that contain rarefied neon or other gases. They are the most common use for neon lighting, which was first demonstrated in a modern form in December 1910 by Georges Claude at the Paris Motor Show. While they are used worldwide, neon signs were popular in the United States from about the 1920s to 1950s. The installations in Times Square, many originally designed by Douglas Leigh, were famed, and there were nearly 2,000 small shops producing neon signs by 1940. Pages 221–223 describe Moore tubes. Pages 369–374 describe neon tube lighting. Page 385 discusses Risler's contributions to fluorescent coatings in the 1920s. Pages 388–391 discuss the development of the commercial fluorescent at General Electric in the 1930s. In addition to signage, neon lighting is used frequently by artists and architects, and (in a modified form) in plasma display panels and televisions. Paid ...

Glow Discharge
A glow discharge is a plasma formed by the passage of electric current through a gas. It is often created by applying a voltage between two electrodes in a glass tube containing a low-pressure gas. When the voltage exceeds a value called the striking voltage, the gas ionization becomes self-sustaining, and the tube glows with a colored light. The color depends on the gas used. Glow discharges are used as a source of light in devices such as neon lights, fluorescent lamps, and plasma-screen televisions. Analyzing the light produced with spectroscopy can reveal information about the atomic interactions in the gas, so glow discharges are used in plasma physics and analytical chemistry. They are also used in the surface treatment technique called sputtering. Electrical conduction in gas Conduction in a gas requires charge carriers, which can be either electrons or ions. Charge carriers come from ionizing some of the gas molecules. In terms of current flow, glow discharge fall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paris Opera
The Paris Opera (, ) is the primary opera and ballet company of France. It was founded in 1669 by Louis XIV as the , and shortly thereafter was placed under the leadership of Jean-Baptiste Lully and officially renamed the , but continued to be known more simply as the . Classical ballet as it is known today arose within the Paris Opera as the Paris Opera Ballet and has remained an integral and important part of the company. Currently called the , it mainly produces operas at its modern 2,723-seat theatre Opéra Bastille which opened in 1989, and ballets and some classical operas at the older 1,979-seat Palais Garnier which opened in 1875. Small scale and contemporary works are also staged in the 500-seat Amphitheatre under the Opéra Bastille. The company's annual budget is in the order of 200 million euros, of which €100M come from the French state and €70M from box office receipts. With this money, the company runs the two houses and supports a large permanent st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cinzano
Cinzano () is an Italian brand of vermouth, a brand owned since 1999 by Gruppo Campari. History Cinzano vermouths date back to 1757 and the Turin herbal shop of two brothers, Giovanni Giacomo and Carlo Stefano Cinzano, who created a new "vermouth rosso" (red vermouth) using "aromatic plants from the Italian Alps in a till-secretrecipe combining 35 ingredients (including marjoram, thyme, and yarrow)". What became known as the "vermouth of Turin" proved popular with the bourgeoisie of Turin and, later, Casanova. Cinzano Bianco followed, based on a different combination of herbs that included artemisia ( wormwood), cinnamon, cloves, citrus and gentian; it was followed by an Extra Dry version. Exports began in the 1890s, to Argentina, Brazil and the USA, among others. In Paris in 1913, Cinzano was the first product to be advertised with a neon sign on its roof. Cinzano remained a family-run business until 1985. Beginning that year, the Marone family, Turin industrialists, beg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grand Palais
The Grand Palais des Champs-Élysées ( en, Great Palace of the Elysian Fields), commonly known as the Grand Palais (English: Great Palace), is a historic site, exhibition hall and museum complex located at the Champs-Élysées in the 8th arrondissement of Paris, France. Construction of the Grand Palais began in 1897 following the demolition of the Palais de l'Industrie (Palace of Industry) to prepare for the Universal Exposition of 1900. That exposition also produced the adjacent Petit Palais and Pont Alexandre III. The building was designed to be a large-scale venue for official artistic events. A pediment on the building refers to this function with an inscription that reads, "a monument dedicated by the Republic to the glory of French art." Designed according to Beaux-Arts tastes, the building features ornate stone facades, glass vaults and period innovations that included iron and light steel framing and reinforced concrete. It is listed as a historic monument ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peristyle
In ancient Greek and Roman architecture, a peristyle (; from Greek ) is a continuous porch formed by a row of columns surrounding the perimeter of a building or a courtyard. Tetrastoön ( grc, τετράστῳον or τετράστοον, lit=four arcades, label=none) is a rarely used archaic term for this feature. The peristyle in a Greek temple is a peristasis (). In the Christian ecclesiastical architecture that developed from the Roman basilica, a courtyard peristyle and its garden came to be known as a cloister. Etymology The Greek word περίστυλον ''perístylon'' is composed of περί ''peri'', "around" or "surrounded", and στῦλος ''stylos'', "column" or "pillar", together meaning "surrounded by columns/pillars". It was Latinised into synonyms ''peristylum'' and ''peristylium''. In Roman architecture In rural settings, a wealthy Roman could surround a villa with terraced gardens; within the city, Romans created their gardens inside the ''domus''. The ...

Louisiana Purchase Exposition
The Louisiana Purchase Exposition, informally known as the St. Louis World's Fair, was an World's fair, international exposition held in St. Louis, Missouri, United States, from April 30 to December 1, 1904. Local, state, and federal funds totaling $15 million were used to finance the event. More than 60 countries and 43 of the then-45 American states maintained exhibition spaces at the fair, which was attended by nearly 19.7 million people. Historians generally emphasize the prominence of the themes of Race (human categorization), race and imperialism, and the fair's long-lasting impact on intellectuals in the fields of history, art history, architecture and anthropology. From the point of view of the memory of the average person who attended the fair, it primarily promoted entertainment, consumer goods and popular culture. The monumental Greco-Roman architecture of this and other fairs of the era did much to influence permanent new buildings and master plans of major cities. ...

Radio Wave
Radio waves are a type of electromagnetic radiation with the longest wavelengths in the electromagnetic spectrum, typically with frequencies of 300 gigahertz ( GHz) and below. At 300 GHz, the corresponding wavelength is 1 mm (shorter than a grain of rice); at 30 Hz the corresponding wavelength is (longer than the radius of the Earth). Like all electromagnetic waves, radio waves in a vacuum travel at the speed of light, and in the Earth's atmosphere at a close, but slightly lower speed. Radio waves are generated by charged particles undergoing acceleration, such as time-varying electric currents. Naturally occurring radio waves are emitted by lightning and astronomical objects, and are part of the blackbody radiation emitted by all warm objects. Radio waves are generated artificially by an electronic device called a transmitter, which is connected to an antenna which radiates the waves. They are received by another antenna connected to a radio receiver, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

William Ramsay
Sir William Ramsay (; 2 October 1852 – 23 July 1916) was a Scottish chemist who discovered the noble gases and received the Nobel Prize in Chemistry in 1904 "in recognition of his services in the discovery of the inert gaseous elements in air" along with his collaborator, John William Strutt, 3rd Baron Rayleigh, who received the Nobel Prize in Physics that same year for their discovery of argon. After the two men identified argon, Ramsay investigated other atmospheric gases. His work in isolating argon, helium, neon, krypton, and xenon led to the development of a new section of the periodic table. Early years Ramsay was born at 2 Clifton StreetGlasgow Post Office Directory 1852 in Glasgow on 2 October 1852, the son of civil engineer and surveyor, William C. Ramsay, and his wife, Catherine Robertson. The family lived at 2 Clifton Street in the city centre, a three-storey and basement Georgian townhouse.
