Jean-Baptiste Delambre
Jean Baptiste Joseph, chevalier Delambre (19 September 1749 – 19 August 1822) was a French mathematician, astronomer, historian of astronomy, and geodesist. He was also director of the Paris Observatory, and author of well-known books on the history of astronomy from ancient times to the 18th century. Biography After a childhood fever, he suffered from very sensitive eyes, and believed that he would soon go blind. For fear of losing his ability to read, he devoured any book available and trained his memory. He thus immersed himself in Greek and Latin literature, acquired the ability to recall entire pages verbatim weeks after reading them, became fluent in Italian, English and German and even wrote an unpublished ''Règle ou méthode facile pour apprendre la langue anglaise'' (Easy rule or method for learning English). Delambre's quickly achieved success in his career in astronomy, such that in 1788, he was elected a foreign member of the Royal Swedish Academy of Scienc ...

The town was fought over during both World Wars, suffering significant damage, and was repeatedly occupied by both sides. The 1918 Battle of Amiens was the opening phase of the Hundred Days Offensive which directly led to the Armistice with Germany. The Royal Air Force heavily bombed the town during the Second World War. In the aftermath, the city was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Equator
The equator is a circle of latitude, about in circumference, that divides Earth into the Northern and Southern hemispheres. It is an imaginary line located at 0 degrees latitude, halfway between the North and South poles. The term can also be used for any other celestial body that is roughly spherical. In spatial (3D) geometry, as applied in astronomy, the equator of a rotating spheroid (such as a planet) is the parallel (circle of latitude) at which latitude is defined to be 0°. It is an imaginary line on the spheroid, equidistant from its poles, dividing it into northern and southern hemispheres. In other words, it is the intersection of the spheroid with the plane perpendicular to its axis of rotation and midway between its geographical poles. On and near the equator (on Earth), noontime sunlight appears almost directly overhead (no more than about 23° from the zenith) every day, year-round. Consequently, the equator has a rather stable daytime temperature throug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Astronomy
Astronomy is the oldest of the natural sciences, dating back to antiquity, with its origins in the religious, mythological, cosmological, calendrical, and astrological beliefs and practices of prehistory: vestiges of these are still found in astrology, a discipline long interwoven with public and governmental astronomy. It was not completely separated in Europe (see astrology and astronomy) during the Copernican Revolution starting in 1543. In some cultures, astronomical data was used for astrological prognostication. Early history Early cultures identified celestial objects with gods and spirits. They related these objects (and their movements) to phenomena such as rain, drought, seasons, and tides. It is generally believed that the first astronomers were priests, and that they understood celestial objects and events to be manifestations of the divine, hence early astronomy's connection to what is now called astrology.

Geodesy
Geodesy ( ) is the Earth science of accurately measuring and understanding Earth's figure (geometric shape and size), orientation in space, and gravity. The field also incorporates studies of how these properties change over time and equivalent measurements for other planets (known as '' planetary geodesy''). Geodynamical phenomena, including crustal motion, tides and polar motion, can be studied by designing global and national control networks, applying space geodesy and terrestrial geodetic techniques and relying on datums and coordinate systems. The job title is geodesist or geodetic surveyor. History Definition The word geodesy comes from the Ancient Greek word ''geodaisia'' (literally, "division of Earth"). It is primarily concerned with positioning within the temporally varying gravitational field. Geodesy in the German-speaking world is divided into "higher geodesy" ( or ), which is concerned with measuring Earth on the global scale, and "practical geodes ...

First Consul
The Consulate (french: Le Consulat) was the top-level Government of France from the fall of the Directory in the coup of 18 Brumaire on 10 November 1799 until the start of the Napoleonic Empire on 18 May 1804. By extension, the term ''The Consulate'' also refers to this period of French history. During this period, Napoleon Bonaparte, as First Consul (), established himself as the head of a more authoritarian, autocratic, and centralized republican government in France while not declaring himself sole ruler. Due to the long-lasting institutions established during these years, Robert B. Holtman has called the Consulate "one of the most important periods of all French history." Napoleon brought authoritarian personal rule which has been viewed as military dictatorship. Fall of the Directory government French military disasters in 1798 and 1799 had shaken the Directory, and eventually shattered it in November 1799. Historians sometimes date the start of the political down ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flight To Varennes
The royal Flight to Varennes (french: Fuite à Varennes) during the night of 20–21 June 1791 was a significant event in the French Revolution in which King Louis XVI of France, Queen Marie Antoinette, and their immediate family unsuccessfully attempted to escape from Paris in order to initiate a counter-revolution at the head of loyal troops under royalist officers concentrated at Montmédy near the frontier. They escaped only as far as the small town of Varennes-en-Argonne, where they were arrested after having been recognized at their previous stop in Sainte-Menehould. This incident was a turning point after which popular hostility towards the French monarchy as an institution, as well as towards the king and queen as individuals, became much more pronounced. The king's attempted flight provoked charges of treason that ultimately led to his execution in 1793. The escape failed due to a series of misadventures, delays, misinterpretations and poor judgments. Much was due to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louis XVI
Louis XVI (''Louis-Auguste''; ; 23 August 175421 January 1793) was the last King of France before the fall of the monarchy during the French Revolution. He was referred to as ''Citizen Louis Capet'' during the four months just before he was executed by guillotine. He was the son of Louis, Dauphin of France, son and heir-apparent of King Louis XV, and Maria Josepha of Saxony. When his father died in 1765, he became the new Dauphin.
