French Aerostatic Corps
The French Aerostatic Corps or Company of Aeronauts (french: compagnie d'aérostiers) was the world's first balloon unit, Jeremy Beadle and Ian Harrison, ''First, Lasts & Onlys: Military'', p. 42 founded in 1794 to use balloons, primarily for reconnaissance. Experimentation Numerous suggestions had been made for the use of balloons during the French Revolutionary Wars, and in 1793 the Committee of Public Safety began testing their potential. Initial tests of airship designs proved unsatisfactory.F. Stansbury Haydon, ''Military Ballooning During the Early Civil War'', pp.5-15 However, experiments conducted near the Tuileries from September to October 1793 to produce the required hydrogen without the use of sulphuric acid, which was in short supply, were successful, producing more than 20 cubic metres.Charles Coulston Gillispie, ''Science and Polity in France: The Revolutionary and Napoleonic Years'', pp. 372-373 As a result, the Committee determined to use this technique to flo ...

Reconnaissance
In military operations, reconnaissance or scouting is the exploration of an area by military forces to obtain information about enemy forces, terrain, and other activities. Examples of reconnaissance include patrolling by troops (skirmishers, long-range reconnaissance patrol, U.S. Army Rangers, cavalry scouts, or military intelligence specialists), ships or submarines, crewed or uncrewed reconnaissance aircraft, satellites, or by setting up observation posts. Espionage is usually considered to be different from reconnaissance, as it is performed by non-uniformed personnel operating behind enemy lines. Often called recce (British, Canadian and Australian English) or recon (American English), the word for this activity has at its root the associated verb ''reconnoitre'' or ''reconnoiter''. Etymology The word from the Middle French ''reconoissance''. Overview Reconnaissance conducted by ground forces includes special reconnaissance, armored reconnaissance, amp ...

Army Of The North (France)
The Army of the North or Armée du Nord is a name given to several historical units of the French Army. The first was one of the French Revolutionary Armies that fought with distinction against the First Coalition from 1792 to 1795. Others existed during the Peninsular War, the Hundred Days and the Franco-Prussian War. Campaigns 1791 to 1797 At the creation of the Army of the North on 14 December 1791, the government of the Kingdom of France appointed Jean-Baptiste Donatien de Vimeur, Comte de Rochambeau, as its commander. Rochambeau was replaced in May 1792, and he retired from service. The suspicious government of the First French Republic later charged him with treason and he barely escaped execution. In 1792-1794, the guillotine awaited military commanders who either failed, belonged to the nobility, or displayed insufficient revolutionary zeal. In the Army of the North these unfortunates included Nicolas Luckner, Adam Custine, and Jean Houchard. Under Charles François ...

Maubeuge
Maubeuge (; historical nl, Mabuse or nl, Malbode; pcd, Maubeuche) is a commune in the Nord department in northern France. It is situated on both banks of the Sambre (here canalized), east of Valenciennes and about from the Belgian border. History Maubeuge (ancient ''Malbodium'', from Latin, derived from the Old Frankish name ''Malboden'', meaning "assizes of Boden") owes its origin to Maubeuge Abbey, a double monastery, for men and women, founded in the 7th century by Saint Aldego, the relics of whom are preserved in the church. It subsequently belonged to the territory of Hainaut. The town was part of the Spanish Netherlands and changed hands a number of times before it was finally ceded to France in the 1678 Treaty of Nijmegen. As part of Vauban's ''pré carré'' plan that protected France's northern borders with a double line of fortresses, it was extensively fortified as directed by Louis XIV of France. Besieged in 1793 by Prince Josias of Saxe-Coburg-Saa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Propaganda
Propaganda is communication that is primarily used to influence or persuade an audience to further an agenda, which may not be objective and may be selectively presenting facts to encourage a particular synthesis or perception, or using loaded language to produce an emotional rather than a rational response to the information that is being presented. Propaganda can be found in news and journalism, government, advertising, entertainment, education, and activism and is often associated with material which is prepared by governments as part of war efforts, political campaigns, health campaigns, revolutionaries, big businesses, ultra-religious organizations, the media, and certain individuals such as soapboxers. In the 20th century, the English term ''propaganda'' was often associated with a manipulative approach, but historically, propaganda has been a neutral descriptive term of any material that promotes certain opinions or ideologies. Equivalent non-English terms have also l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carpentry
Carpentry is a skilled trade and a craft in which the primary work performed is the cutting, shaping and installation of building materials during the construction of buildings, ships, timber bridges, concrete formwork, etc. Carpenters traditionally worked with natural wood and did rougher work such as framing, but today many other materials are also used and sometimes the finer trades of cabinetmaking and furniture building are considered carpentry. In the United States, 98.5% of carpenters are male, and it was the fourth most male-dominated occupation in the country in 1999. In 2006 in the United States, there were about 1.5 million carpentry positions. Carpenters are usually the first tradesmen on a job and the last to leave. Carpenters normally framed post-and-beam buildings until the end of the 19th century; now this old-fashioned carpentry is called timber framing. Carpenters learn this trade by being employed through an apprenticeship training—normally 4 years—a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemistry
Chemistry is the scientific study of the properties and behavior of matter. It is a natural science that covers the elements that make up matter to the compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances. Chemistry also addresses the nature of chemical bonds in chemical compounds. In the scope of its subject, chemistry occupies an intermediate position between physics and biology. It is sometimes called the central science because it provides a foundation for understanding both basic and applied scientific disciplines at a fundamental level. For example, chemistry explains aspects of plant growth ( botany), the formation of igneous rocks ( geology), how atmospheric ozone is formed and how environmental pollutants are degraded ( ecology), the properties of the soil on the moon ( cosmochemistry), how medications work ( pharmacology), and how to collec ...

Hydrogen Production
Hydrogen production is the family of industrial methods for generating hydrogen gas. As of 2020, the majority of hydrogen (∼95%) is produced from fossil fuels by steam reforming of natural gas and other light hydrocarbons, partial oxidation of heavier hydrocarbons, and coal gasification. Other methods of hydrogen production include biomass gasification, zero-CO2-emission methane pyrolysis, and electrolysis of water. The latter processes, methane pyrolysis as well as water electrolysis can be done directly with any source of electricity, such as solar power. The production of hydrogen plays a key role in any industrialized society, since hydrogen is required for many essential chemical processes. In 2020, roughly 87 million tons of hydrogen was produced worldwide for various uses, such as oil refining, and in the production of ammonia (NH3) (through the Haber process) and methanol (CH3OH) (through reduction of carbon monoxide O, and also as a fuel in transportation.

Nicolas-Jacques Conté
Nicolas-Jacques Conté (4 August 1755 – 6 December 1805) was a French painter, balloonist, army officer, and inventor of the modern pencil. He was born at Saint-Céneri-près-Sées (now Aunou-sur-Orne) in Normandy and distinguished himself for his mechanical genius, which was of great avail to the French army in Egypt. Napoleon called him “a universal man with taste, understanding and genius capable of creating the arts of France in the middle of the Arabian Desert”. Aeronautics One of his early interests while still at Sées was in the newly developing science of aeronautics. He made at least one hot-air balloon, which he flew in the public square. He contributed to the improvement of the production of hydrogen gas, as well as the treatment of the gas bag of the balloon itself. In Egypt, Conté was called on to exercise his expertise in ballooning and was asked to prepare an ascent for the celebration of the French New Year on 22 September 1798. He was not sufficien ...

Ernest Dominique François Joseph Duquesnoy
Ernest Dominique François Joseph Duquesnoy (17 May 1749, in Bouvigny-Boyeffles – 17 June 1795, in Paris ) was a French revolutionary. Life The son of a farmer, he served time as a private in the dragoons then (at the start of the French Revolution) moved to farming and raising his large family. He was elected a député for the Pas-de-Calais to the Assemblée nationale législative (First Republic), Assemblée législative, then to the National Convention. At the trial of Louis XVI he voted for death without appeal to the people, not for the sentence, and forced his colleague Bollet to vote the same by threats. He took on many missions to the Nord and was absent during the struggle between the The Mountain, Montagnards and Girondists. He was sent to Dunkirk with Lazare Carnot and fought with courage at the Battle of Wattignies, where he charged the enemy at the head of his troops. He was very severe with incompetent generals, notably dismissing Jean Nestor de Chancel and Jean- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
