Château De Montlhéry
The Château de Montlhéry is a castle in the ''Communes of France, commune'' of Montlhéry in the Essonne ''Departments of France, département'' of France. Ruins date from various periods, most notably the 10th, 11th, 13th and 14th centuries. The present 13th-century castle, with its prominent keep, succeeded a castle built in the 11th century, and an earlier foundation, built from 991 to 1015. The castle is a rectilinear pentagonal plan, with five surviving towers, one of which is much larger than the rest and serves as the keep, forming the point of the pentagon, at the end of the ridge. A gate tower protected the entrance on the opposite site. Recent evidence suggests that there may have a second court or bailey extending in front of the present gate, as well as a substantial chapel inside the presumed lower court. Thanks to its position, the keep was notably connected with the scientific experiments of Pierre Gassendi (measurement of the speed of sound), Claude Chappe (expe ...

Alfred Cornu
Marie Alfred Cornu (; 6 March 1841 – 12 April 1902) was a French physicist and professor of École polytechnique. The French generally refer to him as Alfred Cornu. The Cornu spiral, a graphical device for the computation of light intensities in Fresnel's model of near-field diffraction, is named after him. The spiral (or clothoid) is also used in geometric design of roads. The Cornu depolarizer is also named after him. Life Cornu was born at Orléans to François Cornu and Sophie Poinsellier. He was educated at the École polytechnique and the École des mines. Upon the death of Émile Verdet in 1866, Cornu became, in 1867, Verdet's successor as professor of experimental physics at the École polytechnique, where he remained throughout his life. Although he made various excursions into other branches of physical science, undertaking, for example, with Jean-Baptistin Baille about 1870 a repetition of Cavendish's experiment for determining the gravitational constant ''G'', hi ...

Curtain Wall (fortification)
A curtain wall is a defensive wall between fortified towers or bastions of a castle, fortress, or town. Ancient fortifications Evidence for curtain walls or a series of walls surrounding a town or fortress can be found in the historical sources from Assyria and Egypt. Some notable examples are ancient Tel Lachish in Israel and Buhen in Egypt. Curtain walls were built across Europe during the Roman Empire; the early 5th century Theodosian Walls of Constantinople influenced the builders of medieval castles many centuries later. Curtain wall castles In medieval castles, the area surrounded by a curtain wall, with or without towers, is known as the bailey. The outermost walls with their integrated bastions and wall towers together make up the enceinte or main defensive line enclosing the site. In medieval designs of castle and town, the curtain walls were often built to a considerable height and were fronted by a ditch or moat to make assault difficult. Walls were topped ...

Moat
A moat is a deep, broad ditch dug around a castle, fortification, building, or town, historically to provide it with a preliminary line of defence. Moats can be dry or filled with water. In some places, moats evolved into more extensive water defences, including natural or artificial lakes, dams and sluices. In older fortifications, such as hillforts, they are usually referred to simply as ditches, although the function is similar. In later periods, moats or water defences may be largely ornamental. They could also act as a sewer. Historical use Ancient Some of the earliest evidence of moats has been uncovered around ancient Egyptian fortresses. One example is at Buhen, a settlement excavated in Nubia. Other evidence of ancient moats is found in the ruins of Babylon, and in reliefs from ancient Egypt, Assyria, and other cultures in the region. Evidence of early moats around settlements has been discovered in many archaeological sites throughout Southeast Asia, including ...

Claude Chappe
Claude Chappe (; 25 December 1763 – 23 January 1805) was a French inventor who in 1792 demonstrated a practical semaphore line, semaphore system that eventually spanned all of France. His system consisted of a series of towers, each within line of sight of others, each supporting a wooden mast with two crossarms on pivots that could be placed in various positions. The operator in a tower moved the arms to a sequence of positions, spelling out text messages in semaphore code. The operator in the next tower read the message through a telescope, then passed it on to the next tower. This was the first practical telecommunications system of the industrial age, and was used until the 1850s when electric telegraph systems replaced it. Early life Claude Chappe was born in Brûlon, Sarthe, France, the son of Ignace Chappe, a ''contrôleur'' (Intendant (government official), intendant) of the Crown lands of France, Crown lands for Laval, Mayenne, Laval, and his wife Marie Devernay, ...

Plan
A plan is typically any diagram or list of steps with details of timing and resources, used to achieve an Goal, objective to do something. It is commonly understood as a modal logic, temporal set (mathematics), set of intended actions through which one expects to achieve a goal. For space, spatial or Plane (geometry), planar topology, topologic or topography, topographic sets see map. Plans can be formal or informal: * Structured and formal plans, used by multiple people, are more likely to occur in projects, diplomacy, careers, economic development, military campaigns, combat, sports, games, or in the conduct of other business. In most cases, the absence of a well-laid plan can have adverse effects: for example, a non-robust project plan can cost the organization time and money. * Informal or ad hoc plans are created by individuals in all of their pursuits. The most popular ways to describe plans are by their breadth, time frame, and specificity; however, these planning clas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pierre Gassendi
Pierre Gassendi (; also Pierre Gassend, Petrus Gassendi, Petrus Gassendus; 22 January 1592 – 24 October 1655) was a French philosopher, Catholic priest, astronomer, and mathematician. While he held a church position in south-east France, he also spent much time in Paris, where he was a leader of a group of free-thinking intellectuals. He was also an active observational scientist, publishing the first data on the transit of Mercury in 1631. The lunar crater Gassendi is named after him. He wrote numerous philosophical works, and some of the positions he worked out are considered significant, finding a way between skepticism and dogmatism. Richard Popkin indicates that Gassendi was one of the first thinkers to formulate the modern "scientific outlook", of moderated skepticism and empiricism. He clashed with his contemporary Descartes on the possibility of certain knowledge. His best known intellectual project attempted to reconcile Epicurean atomism with Christianity. ...

Keep
A keep is a type of fortified tower built within castles during the Middle Ages by European nobility. Scholars have debated the scope of the word ''keep'', but usually consider it to refer to large towers in castles that were fortified residences, used as a refuge of last resort should the rest of the castle fall to an adversary. The first keeps were made of timber and formed a key part of the motte-and-bailey castles that emerged in Normandy and Anjou during the 10th century; the design spread to England, Portugal, south Italy and Sicily. As a result of the Norman Conquest of England in 1066, use spread into Wales during the second half of the 11th century and into Ireland in the 1170s. The Anglo-Normans and French rulers began to build stone keeps during the 10th and 11th centuries, including Norman keeps, with a square or rectangular design, and circular shell keeps. Stone keeps carried considerable political as well as military importance and could take a decade or more t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
