Louchuan
Louchuan (traditional Chinese: , simplified: , pinyin: ''lóuchuán'', lit. ''tower ships'') were a type of Chinese naval vessels, primarily a floating fortress, which have seen use since the Han dynasty. Meant to be a central vessel in the fleet, the louchuan was equipped for boarding and attacking enemy vessels, as well as with siege weapons including Trebuchet#Traction trebuchet, traction trebuchets for ranged combat.Needham, Joseph (translated by), ''Taibai Yinjing'', Volume 4, Part 2, pg. 685. Description Historical records relating to the louchuan are found in sources such as the Song dynasty military treatise ''Wujing Zongyao'', written during the Song dynasty, and the ''Taibai Yinjing'' from the Tang dynasty. From the latter (as translated by British biochemist, sinologist, and historian Joseph Needham), the tower ships were described as: The use of such ships in riverine warfare, especially along the Yangtze River, Chang Jiang, stretches back to the late Han dynasty, a ...

Chinese Inventions
China has been the source of many innovations, scientific discoveries and inventions. This includes the ''Four Great Inventions'': papermaking, the compass, gunpowder, and printing (both woodblock and movable type). The list below contains these and other inventions in ancient and modern China attested by archaeological or historical evidence, excluding prehistoric inventions of Neolithic and early Bronze Age China. The historical region now known as China experienced a history involving mechanics, hydraulics and mathematics applied to horology, metallurgy, astronomy, agriculture, engineering, music theory, craftsmanship, naval architecture and warfare. Use of the plow during the Neolithic period Longshan culture (c. 3000–c. 2000 BC) allowed for high agricultural production yields and rise of Chinese civilization during the Shang Dynasty (c. 1600–c. 1050 BC). Later inventions such as the multiple-tube seed drill and the heavy moldboard iron plow enabled China to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval History Of China
The naval history of China dates back thousands of years, with archives existing since the late Spring and Autumn period regarding the Chinese navy and the various ship types employed in wars.Needham, Volume 4, Part 3, 678. The Ming dynasty of China was the leading global maritime power between 1400 and 1433, when Chinese shipbuilders built massive ocean-going junks and the Chinese imperial court launched seven maritime voyages. In modern times, the current People's Republic of China and the Republic of China governments continue to maintain standing navies through the People's Liberation Army Navy and the Republic of China Navy, respectively. History Early coastal maritime endeavours The Han dynasty established the first independent naval force in China, the Tower Ship Navy. Although naval battles took place before the 12th century, such as the large-scale Three Kingdoms Battle of Chibi in the year 208, it was during the Song Dynasty (960–1279) that the Chinese establishe ...

Forecastle
The forecastle ( ; contracted as fo'c'sle or fo'c's'le) is the upper deck of a sailing ship forward of the foremast, or, historically, the forward part of a ship with the sailors' living quarters. Related to the latter meaning is the phrase " before the mast" which denotes anything related to ordinary sailors, as opposed to a ship's officers. History and design In medieval shipbuilding, a ship of war was usually equipped with a tall, multi-deck castle-like structure in the bow of the ship. It served as a platform for archers to shoot down on enemy ships, or as a defensive stronghold if the ship were boarded. A similar but usually much larger structure, called the aftcastle, was at the aft end of the ship, often stretching all the way from the main mast to the stern. Having such tall upper works on the ship was detrimental to sailing performance. As cannons were introduced and gunfire replaced boarding as the primary means of naval combat during the 16th century, the medieval ...

Battle Of Lake Poyang
The Battle of Lake Poyang () was a naval conflict which took place (30 August – 4 October 1363) between the rebel forces of Zhu Yuanzhang and Chen Youliang during the Red Turban Rebellion which led to the fall of the Yuan dynasty. Chen Youliang besieged Nanchang with a large fleet on Lake Poyang, one of China's largest freshwater lakes, and Zhu Yuanzhang met his force with a smaller fleet. After an inconclusive engagement exchanging fire, Zhu employed fire ships to burn the enemy tower ships and destroyed their fleet. This was the last major battle of the rebellion prior to the rise of the Ming dynasty. Background On 30 August 1363, the forces of Chen Han conducted a major amphibious assault on Nanchang but failed to take it due to the defenders' use of cannons and suffered great losses. The town of Nanchang was strategically located to guard Lake Poyang, which connected the Yangzi with other river basins. During the early 1360s Zhu Yuanzhang held key garrisons on the lake an ...

Wang Jun (Jin Dynasty)
Wang Jun (206 – 28 January 286''gengzi'' day of the 12th month of the 6th year of the ''Taikang'' era, per Emperor Wu's biography in ''Book of Jin''), courtesy name Shizhi, was a military general who lived during the late Three Kingdoms period and early Western Jin dynasty of China. Life Wang Jun was from Hu County (湖縣), Hongnong Commandery (弘農郡), which is located west of present-day Lingbao, Henan. He was born in a family of government officials. He was known for his good looks, and for being well-read and ambitious. He started his career as an Assistant Officer (從事) in the office of Hedong Commandery (河東郡; around present-day Xia County, Shanxi). Yang Ji (羊暨), a nephew of the Jin dynasty general Yang Hu, once told his uncle to be wary of Wang Jun because he was extravagant and unbridled in his ways. However, Yang Hu recognised Wang Jun as a rare talent and regarded him highly. In 272, after Wang Jun was appointed as the Administrator (太守) of Gu ...

Melting
Melting, or fusion, is a physical process that results in the phase transition of a substance from a solid to a liquid. This occurs when the internal energy of the solid increases, typically by the application of heat or pressure, which increases the substance's temperature to the melting point. At the melting point, the ordering of ions or molecules in the solid breaks down to a less ordered state, and the solid "melts" to become a liquid. Substances in the molten state generally have reduced viscosity as the temperature increases. An exception to this principle is the element sulfur, whose viscosity increases in the range of 160 °C to 180 °C due to polymerization. Some organic compounds melt through mesophases, states of partial order between solid and liquid. First order phase transition From a thermodynamics point of view, at the melting point the change in Gibbs free energy ''∆G'' of the substances is zero, but there are non-zero changes in the enthalpy ...

Trebuchet
A trebuchet (french: trébuchet) is a type of catapult that uses a long arm to throw a projectile. It was a common powerful siege engine until the advent of gunpowder. The design of a trebuchet allows it to launch projectiles of greater weights and further distances than that of a traditional catapult. There are two main types of trebuchet. The first is the traction trebuchet, or mangonel, which uses manpower to swing the arm. It first appeared in China in the 4th century BC. Carried westward by the Avars, the technology was adopted by the Byzantines in the late 6th century AD and by their neighbors in the following centuries. The later, and often larger and more powerful, counterweight trebuchet, also known as the counterpoise trebuchet, uses a counterweight to swing the arm. It appeared in both Christian and Muslim lands around the Mediterranean in the 12th century, and was carried back to China by the Mongols in the 13th century. Etymology and terminology It is uncer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leather
Leather is a strong, flexible and durable material obtained from the tanning, or chemical treatment, of animal skins and hides to prevent decay. The most common leathers come from cattle, sheep, goats, equine animals, buffalo, pigs and hogs, and aquatic animals such as seals and alligators. Leather can be used to make a variety of items, including clothing, footwear, handbags, furniture, tools and sports equipment, and lasts for decades. Leather making has been practiced for more than 7,000 years and the leading producers of leather today are China and India. Animal rights groups claim that modern commercial leather making and the consumption of its products is unethically killing animals. According to the life-cycle assessment (LCA) report for the United Nations Industrial Development Organization, 99% of the raw hides and skins used in the production of leather derive from animals raised for meat and/or dairy production. Critics of tanneries claim that they engage in uns ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
