Jeong Duwon
Jeong Duwon (.1581), also known as Chong Tuwon,. was a Korean mandarin and diplomat. His chance encounter with a generous member of the Jesuit China missions greatly expanded Korean knowledge of western science, technology, geographical knowledge, and culture centuries before it opened its borders to actual visitors from abroad. Life During a diplomatic mission to the Ming in Beijing in early 1631, Jeong stopped at Dengzhou (now Penglai) on the northern coast of Shandong. The normal route was overland, but the Koreans were obliged to travel directly across the Yellow Sea owing to the northern war zones created by the initial phases of the Manchu conquest of China. There, he met with the province's Christian governor under the Ming Ignatius Sun, who introduced him to the Jesuit interpreter João Rodrigues. Rodrigues was working with Gonçalo Teixeira-Correa to train Sun's forces in the use of European-style cannon. He made a personal gift of his telescope to Jeong, which becam ...

Jeong (surname)
Jeong is a Latin alphabet rendition of the Korean family name "정", also often spelled Chung, Jung, Joung or Jong. As of the South Korean census of 2015, there were 2,407,601 people by this name in South Korea or 4.84% of the population. The Korean family name "정" is mainly derived from three homophonous hanja.

Jesuit China Mission
The history of the missions of the Jesuits in China is part of the history of relations between China and the Western world. The missionary efforts and other work of the Society of Jesus, or Jesuits, between the 16th and 17th century played a significant role in continuing the transmission of knowledge, science, and culture between China and the West, and influenced Christian culture in Chinese society today. The first attempt by the Jesuits to reach China was made in 1552 by St. Francis Xavier, Navarrese priest and missionary and founding member of the Society of Jesus. Xavier never reached the mainland, dying after only a year on the Chinese island of Shangchuan. Three decades later, in 1582, Jesuits once again initiated mission work in China, led by several figures including the Italian Matteo Ricci, introducing Western science, mathematics, astronomy, and visual arts to the Chinese imperial court, and carrying on significant inter-cultural and philosophical dialogue with C ...

Reconnaissance
In military operations, reconnaissance or scouting is the exploration of an area by military forces to obtain information about enemy forces, terrain, and other activities. Examples of reconnaissance include patrolling by troops (skirmishers, long-range reconnaissance patrol, U.S. Army Rangers, cavalry scouts, or military intelligence specialists), ships or submarines, crewed or uncrewed reconnaissance aircraft, satellites, or by setting up observation posts. Espionage is usually considered to be different from reconnaissance, as it is performed by non-uniformed personnel operating behind enemy lines. Often called recce (British, Canadian and Australian English) or recon (American English), the word for this activity has at its root the associated verb ''reconnoitre'' or ''reconnoiter''. Etymology The word from the Middle French ''reconoissance''. Overview Reconnaissance conducted by ground forces includes special reconnaissance, armored reconnaissance, amp ...

Pistol
A pistol is a handgun, more specifically one with the chamber integral to its gun barrel, though in common usage the two terms are often used interchangeably. The English word was introduced in , when early handguns were produced in Europe, and is derived from the Middle French ''pistolet'' (), meaning a small gun or knife. In colloquial usage, the word "pistol" is often used to describe any type of handgun, inclusive of revolvers (which have a single barrel and a separate cylinder housing multiple chambers) and the pocket-sized derringers (which are often multi-barrelled). The most common type of pistol used in the contemporary era is the semi-automatic pistol, while the older single-shot and manual repeating pistols are now rarely seen and used primarily for nostalgic hunting and historical reenactment, and the fully automatic machine pistols are uncommon in civilian usage due to generally poor recoil-controllability and strict laws and regulations governing their manufa ...

Musket
A musket is a muzzle-loaded long gun that appeared as a smoothbore weapon in the early 16th century, at first as a heavier variant of the arquebus, capable of penetrating plate armour. By the mid-16th century, this type of musket gradually disappeared as the use of heavy armour declined, but ''musket'' continued as the generic term for smoothbore long guns until the mid-19th century. In turn, this style of musket was retired in the 19th century when rifled muskets (simply called rifles in modern terminology) using the Minié ball (invented by Claude-Étienne Minié in 1849) became common. The development of breech-loading firearms using self-contained cartridges (introduced by Casimir Lefaucheux in 1835) and the first reliable repeating rifles produced by Winchester Repeating Arms Company in 1860 also led to their demise. By the time that repeating rifles became common, they were known as simply "rifles", ending the era of the musket. Etymology According to the Online Et ...

Fieldgun
A field gun is a field artillery piece. Originally the term referred to smaller guns that could accompany a field army on the march, that when in combat could be moved about the battlefield in response to changing circumstances (field artillery), as opposed to guns installed in a fort (garrison artillery or coastal artillery), or to siege cannons and mortars which are too large to be moved quickly, and would be used only in a prolonged siege. Perhaps the most famous use of the field gun in terms of advanced tactics was Napoleon Bonaparte's use of very large wheels on the guns that allowed them to be moved quickly even during a battle. By moving the guns from point-to-point during a battle, enemy formations could be broken up to be handled by the infantry or cavalry wherever they were massing, dramatically increasing the overall effectiveness of the attack. World War I As the evolution of artillery continued, almost all guns of any size became capable of being moved at some spe ...

Christianity In Korea
The practice of Christianity in Korea is marginal in North Korea, but significant in South Korea, where it revolves around two of its largest branches, Protestantism and Catholicism, accounting for 8.6 millionAccording to figures compiled by the South Korean National Statistical Office. and 5.8 million members, respectively. Catholicism was first introduced during the late Joseon Dynasty period by Confucian scholars who encountered it in China. In 1603, Yi Gwang-jeong, a Korean diplomat, returned from Beijing carrying several theological books written by Matteo Ricci, an Italian Jesuit missionary to China.KIM Han-sik, 'The Influence of Christianity', ''Korean Journal'' XXIII, 12, December 1983, p. 5. He began disseminating the information in the books, and the first seeds of Christianity were sown. In 1758, King Yeongjo of Joseon officially outlawed Catholicism as an "evil practice." Catholicism was reintroduced in 1785 by Yi Seung-hun and since then French and Chines ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Giulio Alenio
Giulio Aleni ( la, Julius Alenius; 1582– 10 June 1649), in Chinese , was an Italian Jesuit missionary and scholar. He was born in Leno near Brescia in Italy, at the time part of the Republic of Venice, and died at Yanping in China. He became a member of the Society of Jesus in 1600 and distinguished himself in his knowledge of mathematics and theology. He is known for helping publish the Zhifang Waiji, an atlas in Chinese. Giulio Aleni also wrote a treatise criticizing the Ming dynasty, the Ming emperors and their elites, and their mistakes and errors. Near the end of his life, the Ming dynasty eventually got destroyed and replaced by the Qing dynasty founded by the House of Aisin-Gioro.John Witek, S.J.

Chinese Astronomy
Astronomy in China has a long history stretching from the Shang dynasty, being refined over a period of more than 3,000 years. The ancient Chinese people have identified stars from 1300 BCE, as Chinese star names later categorized in the twenty-eight mansions have been found on oracle bones unearthed at Anyang, dating back to the mid-Shang dynasty. The core of the "mansion" (宿 ''xiù'') system also took shape around this period, by the time of King Wu Ding (1250–1192 BCE). Detailed records of astronomical observations began during the Warring States period (fourth century BCE) and flourished from the Han period onward. Chinese astronomy was equatorial, centered on close observation of circumpolar stars, and was based on different principles from those in traditional Western astronomy, where heliacal risings and settings of zodiac constellations formed the basic ecliptic framework. Joseph Needham has described the ancient Chinese as the most persistent and accurate obser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telescope
A telescope is a device used to observe distant objects by their emission, absorption, or reflection of electromagnetic radiation. Originally meaning only an optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects, the word ''telescope'' now refers to a wide range of instruments capable of detecting different regions of the electromagnetic spectrum, and in some cases other types of detectors. The first known practical telescopes were refracting telescopes with glass lenses and were invented in the Netherlands at the beginning of the 17th century. They were used for both terrestrial applications and astronomy. The reflecting telescope, which uses mirrors to collect and focus light, was invented within a few decades of the first refracting telescope. In the 20th century, many new types of telescopes were invented, including radio telescopes in the 1930s and infrared telescopes in the 1960s. Etymology The word ''telescope'' was coin ...
