Atlas Coelestis
The ''Atlas Coelestis'' is a Star cartography, star atlas published posthumously in 1729, based on observations made by the Astronomer Royal, First Astronomer Royal, John Flamsteed. The ''Atlas'' – the largest that ever had been published and the first comprehensive telescopic star catalogue and companion celestial atlas – contains 26 maps of the major constellations visible from Greenwich, with drawings made in the Rococo style by James Thornhill. It also presents two planispheres designed by Abraham Sharp. History The first stellar atlas based in telescope, telescopic observations, the ''Atlas Coelestis'' was published only ten years after the death of Flamsteed, by his widow, assisted by Joseph Crosthwait and Abraham Sharp. It was preceded by the opus "Stellarum inerrantium Catalogus Britannicus" (or simply "British Catalogue", published in 1725, with 2919 stars). One of Flamsteed's main motivations to produce the ''Atlas'', was to correct the representation of the fig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ptolemy
Claudius Ptolemy (; , ; ; – 160s/170s AD) was a Greco-Roman mathematician, astronomer, astrologer, geographer, and music theorist who wrote about a dozen scientific treatises, three of which were important to later Byzantine science, Byzantine, Islamic science, Islamic, and Science in the Renaissance, Western European science. The first was his astronomical treatise now known as the ''Almagest'', originally entitled ' (, ', ). The second is the ''Geography (Ptolemy), Geography'', which is a thorough discussion on maps and the geographic knowledge of the Greco-Roman world. The third is the astrological treatise in which he attempted to adapt horoscopic astrology to the Aristotelian physics, Aristotelian natural philosophy of his day. This is sometimes known as the ' (, 'On the Effects') but more commonly known as the ' (from the Koine Greek meaning 'four books'; ). The Catholic Church promoted his work, which included the only mathematically sound geocentric model of the Sola ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virgo (constellation)
Virgo is one of the constellations of the zodiac. The name is for maiden in Latin and its traditional astrological symbol is . Between Leo (constellation), Leo to the west and Libra (constellation), Libra to the east, lying in the south, it is the second-largest constellation in the sky (after Hydra (constellation), Hydra) and the largest constellation in the zodiac. The ecliptic intersects the celestial equator within this constellation and Pisces (constellation), Pisces. Underlying these technical two definitions, the sun passes directly overhead of the equator, within this constellation, at the September equinox. Virgo can be easily found through its brightest star, Spica, (in Latin "grain headed"). Location Virgo is prominent in the spring sky in the Northern Hemisphere, visible all night in March and April. As the largest zodiac constellation, the Sun takes 44 days to pass through it, longer than any other. From 1990 and until 2062, this will take place from September 16 ...

Andromeda (constellation)
Andromeda is one of the 48 constellations listed by the 2nd-century Greco-Roman astronomer Ptolemy, and one of the 88 modern constellations. Located in the northern celestial hemisphere, it is named for Andromeda, daughter of Cassiopeia, in the Greek myth, who was chained to a rock to be eaten by the sea monster Cetus. Andromeda is most prominent during autumn evenings in the Northern Hemisphere, along with several other constellations named for characters in the Perseus myth. Because of its northern declination, Andromeda is visible only north of 40° south latitude; for observers farther south, it lies below the horizon. It is one of the largest constellations, with an area of 722 square degrees. This is over 1,400 times the size of the full moon, 55% of the size of the largest constellation, Hydra, and over 10 times the size of the smallest constellation, Crux. Its brightest star, Alpheratz (Alpha Andromedae), is a binary star that has also been counted as a part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

French Academy Of Sciences
The French Academy of Sciences (, ) is a learned society, founded in 1666 by Louis XIV at the suggestion of Jean-Baptiste Colbert, to encourage and protect the spirit of French Scientific method, scientific research. It was at the forefront of scientific developments in Europe in the 17th and 18th centuries, and is one of the earliest Academy of Sciences, Academies of Sciences. Currently headed by Patrick Flandrin (President of the academy), it is one of the five Academies of the . __TOC__ History The Academy of Sciences traces its origin to Colbert's plan to create a general academy.

Charles Messier
Charles Messier (; 26 June 1730 – 12 April 1817) was a French astronomer. He published an astronomical catalogue consisting of 110 nebulae and star clusters, which came to be known as the ''Messier objects'', referred to with the letter M and their number between 1 and 110. Messier's purpose for list of Messier objects, the catalogue was to help astronomical observers distinguish between permanent and transient astronomical event, transient visually diffuse astronomical object, objects in the sky. Biography Messier was born in Badonviller in the Lorraine region of Kingdom of France, France, in 1730, the tenth of twelve children of Françoise B. Grandblaise and Nicolas Messier, a Court usher. Six of his brothers and sisters died while young, and his father died in 1741.

Pierre Charles Le Monnier
Pierre Charles Le Monnier (; 20 November 1715 – 31 May 1799) was a French astronomer. His name is sometimes given as Lemonnier. Biography Le Monnier was born in Paris, where his father Pierre Lemonnier (physicist), Pierre (1675–1757), also an astronomer, was professor of philosophy at the college d'Harcourt. His first recorded astronomical observation was made before he was sixteen, and the presentation of an elaborate lunar map resulted in his admission to the French Academy of Sciences, on 21 April 1736, aged only 20. He was chosen in the same year to accompany Pierre Louis Maupertuis and Alexis Clairaut on their French Geodesic Mission to Lapland, geodetical expedition for arc measurement, measuring a meridian arc of approximately one degree (angle), degree's length to Torne Valley in Lapland (Finland), Lapland. In 1738, shortly after his return, he explained, in a memoir read before the academy, the advantages of John Flamsteed's mode of determining right ascensions. H ...

Jean Nicolas Fortin
Jean Nicolas Fortin (1750–1831) was a French maker of scientific instruments, born on 9 August 1750 in Mouchy-la-Ville in Picardy. Among his customers were such noted scientists as Lavoisier, for whom he made a precision balance, Gay-Lussac, François Arago and Pierre Dulong. Fortin is chiefly remembered for his design of barometer, now called a ''Fortin barometer'', which he introduced in about 1800. In this, the mercury cistern has a glass portion through which the mercury exposed to the atmosphere can be seen, and an ivory needle which was made just to touch its mirror image in the mercury before the reading was taken. This allows for the fact that, when the mercury column in the closed tube falls, the level in the cistern rises, and the difference in height between the two cannot be accurately determined unless the height of the latter is taken into account. In 1776 Fortin produced the ''Atlas céleste de Flamstéed'', a revised and updated edition of Flamsteed's '' Atlas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engineer
Engineers, as practitioners of engineering, are professionals who Invention, invent, design, build, maintain and test machines, complex systems, structures, gadgets and materials. They aim to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin , the origin of the Ir. in the title of engineer in countries like Belgium, The Netherlands, and Indonesia) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of a licensed professional engineer typically include a four-year Bachelor of Engineering, bache ...
