Luís Cruls
Luíz Cruls or Luís Cruls or Louis Ferdinand Cruls (21 January 1848 – 21 June 1908) was a Belgian- Brazilian astronomer and geodesist. He was Director of the Brazilian National Observatory from 1881 to 1908, led the commission charged with the survey and selection of a future site for the capital of Brazil in the Central Plateau, and was co-discoverer of the Great Comet of 1882. Cruls was also an active proponent of efforts to accurately measure solar parallax and towards that end led a Brazilian team in their observations of 1882 Transit of Venus in Punta Arenas, Chile. Early life Cruls was born in 1848 in Diest, Belgium, the son of Philippe Augustin Guillaume Cruls (a civil engineer) and Anne Elizabeth Jordens. From 1863 to 1868, Cruls studied civil engineering at the University of Ghent. In 1869 he undertook training as a military engineer and officer, graduating as a 2nd Lieutenant. Cruls served in the Belgian army, attaining the rank of 1st Lieutenant, until 1873 or 1874 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Transit Of Venus, 1882
The 1882 transit of Venus, which took place on 6 December 1882 (13:57 to 20:15 UTC), was the second and last transit of Venus of the 19th century, the first having taken place eight years earlier in 1874. Many an expedition was sent by European powers to describe both episodes, eight of them alone were approved and financed in 1882 by the United States Congress. Edward James Stone organized the British expeditions sent to observe the transit. Stephen Joseph Perry and Commander Pelham Aldrich, as captain of HMS , observed the transit from an improvised tent observatory in Madagascar. Jean-Charles Houzeau invented in 1871 a heliometer with unequal focal lengths. For the observation of the transit he organized two expeditions: one to San Antonio, Texas, and another to Santiago de Chile. The two expeditions each had an identical copy of Houzeau's heliometer. The French Academy of Sciences organized ten expeditions to various locations, including Florida, Mexico, Haiti, Martini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mars
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, only being larger than Mercury. In the English language, Mars is named for the Roman god of war. Mars is a terrestrial planet with a thin atmosphere (less than 1% that of Earth's), and has a crust primarily composed of elements similar to Earth's crust, as well as a core made of iron and nickel. Mars has surface features such as impact craters, valleys, dunes and polar ice caps. It has two small and irregularly shaped moons, Phobos and Deimos. Some of the most notable surface features on Mars include Olympus Mons, the largest volcano and highest known mountain in the Solar System and Valles Marineris, one of the largest canyons in the Solar System. The Borealis basin in the Northern Hemisphere covers approximately 40% of the planet and may be a large impact feature. Days and seasons on Mars are comparable to those of Earth, as the planets have a similar rotation period ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Proclamation Of The Republic (Brazil)
The Proclamation of the Republic ( pt, Proclamação da República) was a military coup d'état that established the First Brazilian Republic on 15 November 1889. It overthrew the constitutional monarchy of the Empire of Brazil and ended the reign of Emperor Pedro II. The coup took place in Rio de Janeiro, then the capital of the Empire, when a group of military officers of the Imperial Army, led by Marshal Deodoro da Fonseca, staged a coup d'état without the use of violence, deposing Emperor Pedro II and the President of the Council of Ministers of the Empire, the Viscount of Ouro Preto. A provisional government was established that same day, 15 November, with Marshal Deodoro da Fonseca as President of the Republic and head of the interim Government. Background From the 1870s, in the aftermath of the Paraguayan War (also called the War of the Triple Alliance, 1864-1870), some sectors of the elite transitioned into opposition to the current political regime.

Laranjeiras
Laranjeiras (, ''orange trees'') is an upper-middle-class neighborhood located in the South Zone of Rio de Janeiro, Brazil.

Emmanuel Liais
Emmanuel Liais (15 February 1826–5 March 1900) was a French astronomer, botanist and explorer who spent many years in Brazil. He was born in Cherbourg, the son of a wealthy family in the shipbuilding industry. He was an amateur scientist and made some meteorological observations and wrote some papers. The astronomer François Arago took note of one of his papers written in 1852, which determined that the weather in his hometown was milder than that of Paris. He then went to Paris in 1854 and worked at the Paris Observatory. There he assisted Urbain Le Verrier in creating a telegraphic meteorological network. He went to Brazil to observe the solar eclipse of September 7, 1858 and ended up staying there for a long time. He became a close acquaintance of the Brazilian Emperor Dom Pedro II, and became the director of the Imperial Observatory at Rio de Janeiro from January to July 1871 and again from 1874 to 1881. Although the observatory had been founded in 1827, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triangulation
In trigonometry and geometry, triangulation is the process of determining the location of a point by forming triangles to the point from known points. Applications In surveying Specifically in surveying, triangulation involves only angle measurements at known points, rather than measuring distances to the point directly as in trilateration; the use of both angles and distance measurements is referred to as triangulateration. In computer vision Computer stereo vision and optical 3D measuring systems use this principle to determine the spatial dimensions and the geometry of an item. Basically, the configuration consists of two sensors observing the item. One of the sensors is typically a digital camera device, and the other one can also be a camera or a light projector. The projection centers of the sensors and the considered point on the object's surface define a (spatial) triangle. Within this triangle, the distance between the sensors is the base ''b'' and must be kno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pedro II Of Brazil
Dom PedroII (2 December 1825 – 5 December 1891), nicknamed "the Magnanimous" ( pt, O Magnânimo), was the second and last monarch of the Empire of Brazil, reigning for over 58 years. He was born in Rio de Janeiro, the seventh child of Emperor Dom Pedro I of Brazil and Empress Dona Maria Leopoldina and thus a member of the Brazilian branch of the House of Braganza. His father's abrupt abdication and departure to Europe in 1831 left the five-year-old as emperor and led to a grim and lonely childhood and adolescence, obliged to spend his time studying in preparation for rule. His experiences with court intrigues and political disputes during this period greatly affected his later character; he grew into a man with a strong sense of duty and devotion toward his country and his people, yet increasingly resentful of his role as monarch. Pedro II inherited an empire on the verge of disintegration, but he turned Brazil into an emerging power in the international arena. Th ...

Military Engineering
Military engineering is loosely defined as the art, science, and practice of designing and building military works and maintaining lines of military transport and military communications. Military engineers are also responsible for logistics behind military tactics. Modern military engineering differs from civil engineering. In the 20th and 21st centuries, military engineering also includes other engineering disciplines such as mechanical and electrical engineering techniques. According to NATO, "military engineering is that engineer activity undertaken, regardless of component or service, to shape the physical operating environment. Military engineering incorporates support to maneuver and to the force as a whole, including military engineering functions such as engineer support to force protection, counter-improvised explosive devices, environmental protection, engineer intelligence and military search. Military engineering does not encompass the activities undertaken by thos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
