Camera Obscura
A camera obscura (; ) is the natural phenomenon in which the rays of light passing through a aperture, small hole into a dark space form an image where they strike a surface, resulting in an inverted (upside down) and reversed (left to right) projector, projection of the view outside. ''Camera obscura'' can also refer to analogous constructions such as a darkened room, box or tent in which an exterior image is projected inside or onto a translucent screen viewed from outside. ''Camera obscuras'' with a lens in the opening have been used since the second half of the 16th century and became popular as aids for drawing and painting. The technology was developed further into the photographic camera in the first half of the 19th century, when ''camera obscura'' boxes were used to exposure (photography), expose photosensitivity, light-sensitive materials to the projected image. The image (or the principle of its projection) of a lensless ''camera obscura'' is also referred to as a " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Order Of Christ (Portugal)
The Military Order of Christ is a Portuguese honorific order. It is the former order of Knights Templar as it was reconstituted in Portugal. Before 1910, it was known as the Royal Military Order of Our Lord Jesus Christ, and the Order of the Knights of Our Lord Jesus Christ. It was founded in 1318, with the protection of King Denis of Portugal, after the Templars were abolished on 22 March 1312 by the papal bull, '' Vox in excelso'', issued by Pope Clement V. King Denis refused to pursue and persecute the former knights as had occurred in most of the other sovereign states under the political influence of the Catholic Church. Heavily swayed by Philip IV of France, Pope Clement had the Knights Templar annihilated throughout France and most of Europe on charges of heresy, but Denis revived the Templars of Tomar as the Order of Christ, largely for their aid during the ''Reconquista'' and in the reconstruction of Portugal after the wars. Denis negotiated with Clement's successor, J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

National Library Of Portugal
The (Portuguese language, Portuguese for ''National Library of Portugal'') is the Portugal, Portuguese national library. History The library was created by Decree of 29 February 1796, under the name of Royal Public Library of the Court (). The library's objective was to allow the general public access to the court's collections, bucking the trend of the time, when only scholars and sages had access to the treasures, manuscripts, paintings, and books of the royal court. In the dawn of the victory of the Liberals following the Portuguese Civil War and the abolition of the religious orders (1834), the institution was renamed the National Library of Lisbon and was officially entrusted with all or part of the libraries of numerous monasteries and convents. The arrival of these large collections made it necessary to move to larger premises, and the choice fell on the Convento de São Francisco. Over the more than 130 years in which it operated in the Chiado area of Lisbon, the BNL ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Military Engineers
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 CBRN defense and 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.

18th-century Brazilian People
The 18th century lasted from 1 January 1701 (represented by the Roman numerals MDCCI) to 31 December 1800 (MDCCC). During the 18th century, elements of Enlightenment thinking culminated in the Atlantic Revolutions. Revolutions began to challenge the legitimacy of monarchical and aristocratic power structures. The Industrial Revolution began mid-century, leading to radical changes in human society and the environment. The European colonization of the Americas and other parts of the world intensified and associated mass migrations of people grew in size as part of the Age of Sail. During the century, slave trading expanded across the shores of the Atlantic Ocean, while declining in Russia and China. Western historians have occasionally defined the 18th century otherwise for the purposes of their work. For example, the "short" 18th century may be defined as 1715–1789, denoting the period of time between the death of Louis XIV of France and the start of the French Revolution, ...

People From Salvador, Bahia
The term "the people" refers to the public or Common people, common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of Person, persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Declaration on the Rights of Indigenous Peoples, Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independence, independent sovereignty and therefore secession.
