Honcheonsigye
The Honcheonsigye (meaning ''armillary clock'') is an astronomical clock made by Song Yi-Yeong (), a professor of Gwansanggam () (one of the scientific institution of Joseon) in 1669. It was designated as South Korean national treasure number 230 in August 9, 1985. The clock used the alarm clock technology created by Christiaan Huygens in 1657. This relic shows that Huygens' technology was spread to East Asia in just 12 years. Also, It demonstrates the astronomy and mechanical engineering technology of the Joseon Dynasty. The clock has an armillary sphere with a diameter of 40 cm. The sphere is activated by a clockwork mechanism, designed to display the position of the heavens at any given time, as well as displaying the hours and marking their passage with a chiming bell. The device is no longer in working order. The clock is owned by Korea University Museum. It is the only remaining astronomical clock from the Joseon period. The clock was purchased from an antiques ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astronomical Clock
An astronomical clock, horologium, or orloj is a clock with special mechanisms and dials to display astronomical information, such as the relative positions of the Sun, Moon, zodiacal constellations, and sometimes major planets. Definition The term is loosely used to refer to any clock that shows, in addition to the time of day, astronomical information. This could include the location of the Sun and Moon in the sky, the age and Lunar phases, the position of the Sun on the ecliptic and the current zodiac sign, the sidereal time, and other astronomical data such as the Moon's nodes for indicating eclipses), or a rotating star map. The term should not be confused with an ''astronomical regulator'', a high precision but otherwise ordinary pendulum clock used in observatories. Astronomical clocks usually represent the Solar System using the geocentric model. The center of the dial is often marked with a disc or sphere representing the Earth, located at the center of the S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Treasures Of South Korea
National Treasure () is a national-level designation within the heritage preservation system of South Korea for tangible objects of significant artistic, cultural and historical value. Examples of objects include art, artifacts, sites, or buildings. It is administered by the Korea Heritage Service (KHS). Additions to the list are decided by the Cultural Heritage Committee. Many of the registered items are popular tourist attractions for South Korea. Examples include Jongmyo, Bulguksa, Seokguram, and the Tripitaka Koreana at Haeinsa. As of May 2020, there are 327 distinct entries on the list, some composed of a large number of sub-entries. The treasures are numbered according to the order in which they were designated, not according to their individual value. History The first list of Korean cultural treasures was designated by Governor-General of Korea in 1938 during the Japanese occupation with "The Act of Treasures of the Joseon dynasty". In 1955, the South Korean govern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Korean Won
The South Korean won (symbol: ₩; code: KRW; ) is the official currency of South Korea. A single won is divided into 100 jeon, the monetary subunit. The jeon is no longer used for everyday transactions, and it appears only in foreign exchange rates. The currency is issued by the Bank of Korea, based in the capital city of Seoul. Etymology The old "won" was a cognate of the Chinese yuan, which was derived from the Spanish-American silver dollar. It is derived from the hanja (, ), meaning "round", which describes the shape of the silver dollar. The won was subdivided into 100 (), itself a cognate of the East Asian unit of weight mace and synonymous with money in general. The current won (1962 to present) is written in hangul only and does not officially have any hanja associated with it. First South Korean won History The Korean won, Chinese yuan and Japanese yen were all derived from the Spanish-American silver dollar, a coin widely used for international trade bet ...

Armillary Sphere
An armillary sphere (variations are known as spherical astrolabe, armilla, or armil) is a model of objects in the sky (on the celestial sphere), consisting of a spherical framework of rings, centered on Earth or the Sun, that represent lines of celestial longitude and latitude and other astronomically important features, such as the ecliptic. As such, it differs from a celestial globe, which is a smooth sphere whose principal purpose is to map the constellations. It was invented separately, in ancient China possibly as early as the 4th century BC and ancient Greece during the 3rd century BC, with later uses in the Islamic world and Medieval Europe. With the Earth as center, an armillary sphere is known as '' Ptolemaic''. With the Sun as center, it is known as '' Copernican''. The flag of Portugal features an armillary sphere. The armillary sphere is also featured in Portuguese heraldry, associated with the Portuguese discoveries during the Age of Exploration. Manuel I of Po ...

Joseon Dynasty
Joseon ( ; ; also romanized as ''Chosun''), officially Great Joseon (), was a dynastic kingdom of Korea that existed for 505 years. It was founded by Taejo of Joseon in July 1392 and replaced by the Korean Empire in October 1897. The kingdom was founded following the aftermath of the overthrow of Goryeo in what is today the city of Kaesong. Early on, Korea was retitled and the capital was relocated to modern-day Seoul. The kingdom's northernmost borders were expanded to the natural boundaries at the rivers of Yalu River, Amnok and Tumen River, Tuman through the subjugation of the Jurchen people, Jurchens.

Hyeonjong Of Joseon
Hyeonjong (; 14 March 1641 – 17 September 1674), personal name Yi Yeon (), was the 18th monarch of the Joseon of Korea. His reign was mostly marked by heavy conflict among the nation's political factions on various issues, particularly on funeral rites. He was also the only king in Joseon's more than 500 year-long history to not have any concubines. Biography Background Hyeonjong was born in 1641 as the first son of King Hyojong as Yi Yeon, while his father was still in China as a captive of the Qing dynasty; thus he was born at Shenyang before the Qing dynasty officially moved its capital to Beijing after defeating Ming dynasty in 1644, which made him the first and only monarch of Joseon to be born abroad. He returned to Korea in 1645 along with his father and became Crown Prince in 1651. Yesong Controversy The Yesong Controversy refers to a conflict concerning the funeral of Hyojong. When he died in 1659, his son Hyeonjong succeeded his father as the ruler of Joseon. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Christiaan Huygens
Christiaan Huygens, Halen, Lord of Zeelhem, ( , ; ; also spelled Huyghens; ; 14 April 1629 – 8 July 1695) was a Dutch mathematician, physicist, engineer, astronomer, and inventor who is regarded as a key figure in the Scientific Revolution. In physics, Huygens made seminal contributions to optics and mechanics, while as an astronomer he studied the rings of Saturn and discovered its largest moon, Titan (moon), Titan. As an engineer and inventor, he improved the design of telescopes and invented the pendulum clock, the most accurate timekeeper for almost 300 years. A talented mathematician and physicist, his works contain the first idealization of a physical problem by a set of Mathematical model, mathematical parameters, and the first mathematical and mechanistic explanation of an unobservable physical phenomenon.Dijksterhuis, F.J.
