Georges Claude
Georges Claude (24 September 187023 May 1960) was a French engineer and inventor. He is noted for his early work on the industrial liquefaction of air, for the invention and commercialization of neon lighting, and for a large experiment on generating energy by pumping cold seawater up from the depths. He has been considered by some to be "the Edison of France". The Claude process for manufacturing ammonia was named for him. Claude was an active collaborator with the German occupiers of France during the Second World War, for which he was imprisoned in 1945 and stripped of his honors. Early life and career Georges Claude was born on 24 September 1870 in Paris, France, during the city's siege by German forces. Georges Claude studied at the École supérieure de physique et de chimie industrielles de la ville de Paris (ESPCI). He then held several positions. He was an electrical inspector in a cable factory and the laboratory manager in an electric works. He founded and edite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Paris () is the Capital city, capital and List of communes in France with over 20,000 inhabitants, largest city of France. With an estimated population of 2,048,472 residents in January 2025 in an area of more than , Paris is the List of cities in the European Union by population within city limits, fourth-most populous city in the European Union and the List of cities proper by population density, 30th most densely populated city in the world in 2022. Since the 17th century, Paris has been one of the world's major centres of finance, diplomacy, commerce, culture, Fashion capital, fashion, and gastronomy. Because of its leading role in the French art, arts and Science and technology in France, sciences and its early adoption of extensive street lighting, Paris became known as the City of Light in the 19th century. The City of Paris is the centre of the Île-de-France region, or Paris Region, with an official estimated population of 12,271,794 inhabitants in January 2023, or ...

Acetylene
Acetylene (Chemical nomenclature, systematic name: ethyne) is a chemical compound with the formula and structure . It is a hydrocarbon and the simplest alkyne. This colorless gas is widely used as a fuel and a chemical building block. It is unstable in its pure form and thus is usually handled as a solution. Pure acetylene is odorless, but commercial grades usually have a marked odor due to impurities such as divinyl sulfide and phosphine.Compressed Gas Association (1995Material Safety and Data Sheet – Acetylene As an alkyne, acetylene is Saturated and unsaturated compounds, unsaturated because its two carbon atoms are Chemical bond, bonded together in a triple bond. The carbon–carbon triple bond places all four atoms in the same straight line, with CCH bond angles of 180°. The triple bond in acetylene results in a high energy content that is released when acetylene is burned. Discovery Acetylene was discovered in 1836 by Edmund Davy, who identified it as a "new carburet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Engineering Magazine
Engineering is the practice of using natural science, mathematics, and the engineering design process to solve problems within technology, increase efficiency and productivity, and improve systems. Modern engineering comprises many subfields which include designing and improving infrastructure, machinery, vehicles, electronics, materials, and energy systems. The discipline of engineering encompasses a broad range of more specialized fields of engineering, each with a more specific emphasis for applications of mathematics and science. See glossary of engineering. The word ''engineering'' is derived from the Latin . Definition The American Engineers' Council for Professional Development (the predecessor of the Accreditation Board for Engineering and Technology aka ABET) has defined "engineering" as: History Engineering has existed since ancient times, when humans devised inventions such as the wedge, lever, wheel and pulley, etc. The term ''engineering'' is derived ...

Grand Palais
The (; ), commonly known as the , is a historic site, exhibition hall and museum complex located in the 8th arrondissement of Paris between the Champs-Élysées and the Seine, France. Construction of the began in 1897 following the demolition of the Palais de l'Industrie (Palace of Industry) to prepare for the Exposition Universelle (1900), Universal Exposition of 1900. That exposition also produced the adjacent 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 architecture, Beaux-Arts tastes, the building features ornate stone facades, glass vaults and period innovations that included iron and Steel frame, light steel framing and reinforced concrete. It is listed as a historic monument () by the Ministry of Culture (France), Ministry of C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paris Motor Show
The Paris Motor Show () is a biennial auto show in Paris. Held during October, it is one of the most important auto shows, often with many new production automobile and concept car debuts. The show presently takes place in Paris expo Porte de Versailles. The ''Mondial'' is scheduled by the ''Organisation Internationale des Constructeurs d'Automobiles'', which considers it a major international auto show. In 2016, the Paris Motor Show welcomed 1,253,513 visitors, making it the most visited auto show in the world, ahead of Tokyo and Frankfurt.

Daniel McFarlan Moore
Daniel McFarlan Moore (February 27, 1869 – June 15, 1936) was an American electrical engineer and inventor. He developed a novel light source, the "Moore lamp", and a business that produced them in the early 1900s. The Moore lamp was the first commercially viable light-source based on gas discharges instead of incandescence; it was the predecessor to contemporary neon lighting and fluorescent lighting. Paid access. In his later career Moore developed a miniature neon lamp that was extensively used in electronic displays, as well as vacuum tubes that were used in early television systems. Early life He was born in Northumberland, Pennsylvania, on February 27, 1869. Moore was the son of the Reverend Alexander Davis and Maria Louisa Douglas Moore. He graduated from Lehigh University in 1889. Moore married Mary Alice Elliott, of New York City, on June 5, 1895.

Geissler Tube
A Geissler tube is a precursor to modern gas discharge tubes, demonstrating the principles of electrical glow discharge, akin to contemporary neon lights, and central to the discovery of the electron. This device was developed in 1857 by Heinrich Geissler, a German physicist and glassblower. A Geissler tube is composed of a sealed glass cylinder of various shapes, which is partially evacuated and equipped with a metal electrode at each end. It contains rarefied gases—such as neon or argon, air, mercury vapor, or other conductive substances, and sometimes ionizable minerals or metals like sodium. When a high voltage is applied between the electrodes, there is an electric current through the tube, causing gas molecules to ionize by shedding electrons. The free electrons reunite with the ions and the resulting energic atoms emit light via fluorescence, with the emitted color characteristic of the contained material. Colorful decorative Geissler tubes were made in many art ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
