French People
French people () are a nation primarily located in Western Europe that share a common Culture of France, French culture, History of France, history, and French language, language, identified with the country of France. The French people, especially the native speakers of langues d'oïl from northern and central France, are primarily descended from Roman people, Romans (or Gallo-Romans, western European Celts, Celtic and Italic peoples), Gauls (including the Belgae), as well as Germanic peoples such as the Franks, the Visigoths, the Suebi and the Burgundians who settled in Gaul from east of the Rhine after the fall of the Roman Empire, as well as various later waves of lower-level irregular migration that have continued to the present day. The Norsemen also settled in Normandy in the 10th century and contributed significantly to the ancestry of the Normans. Furthermore, regional ethnic minorities also exist within France that have distinct lineages, languages and cultures such ...

Mathematician
A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems. Mathematicians are concerned with numbers, data, quantity, mathematical structure, structure, space, Mathematical model, models, and mathematics#Calculus and analysis, change. History One of the earliest known mathematicians was Thales of Miletus (); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry, by deriving four corollaries to Thales's theorem. The number of known mathematicians grew when Pythagoras of Samos () established the Pythagorean school, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number". It was the Pythagoreans who coined the term "mathematics", and with whom the study of mathematics for its own sake begins. The first woman math ...

Gentleman Of The Bedchamber
Gentleman of the Bedchamber was a title in the Royal Household of the Kingdom of England from the 11th century, later used also in the Kingdom of Great Britain. A Lord of the Bedchamber was a courtier in the Royal Households of the United Kingdom, Royal Household, the term being first used in 1718. The duties of the Lords and Gentlemen of the Bedchamber originally consisted of assisting the monarch with dressing, waiting on him when he ate, guarding access to his bedchamber and closet, and providing companionship. Such functions became less important over time, but provided proximity to the monarch; the holders were thus trusted confidants and often extremely powerful. The offices were in the gift of The Crown and were originally sworn by Royal warrant (document), Royal Warrant directed to the Lord Chamberlain. This is an ''incomplete'' list of noblemen who have served as Lord of the Bedchamber and Gentleman of the Bedchamber: Description and functions There were always several ...

Henry IV Of France
Henry IV (; 13 December 1553 – 14 May 1610), also known by the epithets Good King Henry (''le Bon Roi Henri'') or Henry the Great (''Henri le Grand''), was King of Navarre (as Henry III) from 1572 and King of France from 1589 to 1610. He was the first monarch of France from the House of Bourbon, a cadet branch of the Capetian dynasty. He pragmatically balanced the interests of the Catholic and Protestant parties in France, as well as among the European states. He was assassinated in Paris in 1610 by a Catholic zealot, and was succeeded by his son Louis XIII. Henry was baptised a Catholic but raised as a Huguenot in the Protestant faith by his mother, Queen Jeanne III of Navarre. He inherited the throne of Navarre in 1572 on his mother's death. As a Huguenot, Henry was involved in the French Wars of Religion, barely escaping assassination in the St. Bartholomew's Day massacre. He later led Protestant forces against the French royal army. Henry inherited the thro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louis XIII
Louis XIII (; sometimes called the Just; 27 September 1601 – 14 May 1643) was King of France from 1610 until his death in 1643 and King of Navarre (as Louis II) from 1610 to 1620, when the crown of Navarre was merged with the French crown. Shortly before his ninth birthday, Louis became king of France and Navarre after his father Henry IV was assassinated. His mother, Marie de' Medici, acted as regent during his minority. Mismanagement of the kingdom and ceaseless political intrigues by Marie and her Italian favourites led the young king to take power in 1617 by exiling his mother and executing her followers, including Concino Concini, the most influential Italian at the French court. Louis XIII, taciturn and suspicious, relied heavily on his chief ministers, first Charles d'Albert, duc de Luynes and then Cardinal Richelieu, to govern the Kingdom of France. The King and the Cardinal are remembered for establishing the ''Académie française'', and ending the revolt of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bomb
A bomb is an explosive weapon that uses the exothermic reaction of an explosive material to provide an extremely sudden and violent release of energy. Detonations inflict damage principally through ground- and atmosphere-transmitted mechanical stress, the impact and penetration of pressure-driven projectiles, pressure damage, and explosion-generated effects. Bombs have been utilized since the 11th century starting in East Asia. The term ''bomb'' is not usually applied to explosive devices used for civilian purposes such as construction or mining, although the people using the devices may sometimes refer to them as a "bomb". The military use of the term "bomb", or more specifically aerial bomb action, typically refers to airdropped, unpowered explosive weapons most commonly used by air forces and naval aviation. Other military explosive weapons not classified as "bombs" include shells, depth charges (used in water), or land mines. In unconventional warfare, other names ...

Artillery
Artillery consists of ranged weapons that launch Ammunition, munitions far beyond the range and power of infantry firearms. Early artillery development focused on the ability to breach defensive walls and fortifications during sieges, and led to heavy, fairly immobile siege engines. As technology improved, lighter, more mobile field artillery cannons were developed for battlefield use. This development continues today; modern self-propelled artillery vehicles are highly mobile weapons of great versatility generally providing the largest share of an army's total firepower. Originally, the word "artillery" referred to any group of soldiers primarily armed with some form of manufactured weapon or armour. Since the introduction of gunpowder and cannon, "artillery" has largely meant cannon, and in contemporary usage, usually refers to Shell (projectile), shell-firing Field gun, guns, howitzers, and Mortar (weapon), mortars (collectively called ''barrel artillery'', ''cannon artil ...

Steam Engine
A steam engine is a heat engine that performs Work (physics), mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a Cylinder (locomotive), cylinder. This pushing force can be transformed by a connecting rod and Crank (mechanism), crank into rotational force for work. The term "steam engine" is most commonly applied to reciprocating engines as just described, although some authorities have also referred to the steam turbine and devices such as Hero's aeolipile as "steam engines". The essential feature of steam engines is that they are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including Boiler (power generation), boilers etc.), such as railway steam locomot ...
