Song Dynasty
The Song dynasty ( ) was an Dynasties of China, imperial dynasty of China that ruled from 960 to 1279. The dynasty was founded by Emperor Taizu of Song, who usurped the throne of the Later Zhou dynasty and went on to conquer the rest of the Five Dynasties and Ten Kingdoms period#Ten Kingdoms, Ten Kingdoms, ending the Five Dynasties and Ten Kingdoms period.

12th-century Chinese Historians
1 (one, unit, unity) is a number, numeral, and glyph. It is the first and smallest positive integer of the infinite sequence of natural numbers. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. 1 is the unit of counting or measurement, a determiner for singular nouns, and a gender-neutral pronoun. Historically, the representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral. In mathematics, 1 is the multiplicative identity, meaning that any number multiplied by 1 equals the same number. 1 is by convention not considered a prime number. In digital technology, 1 represents the "on" state in binary code, the foundation of computing. Philosophically, 1 symbolizes the ultimate reality or source of existence in various traditions. In mathematics The number 1 is the first natural number after 0. Each natural number, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexander Neckam
Alexander Neckam (8 September 115731 March 1217) was an English poet, theologian, and writer. He was an abbot of Cirencester Abbey from 1213 until his death. Early life Born on 8 September 1157 in St Albans, Alexander shared his birthday with King Richard I. For this reason, his mother, Hodierna of St Albans, was hired by the royal household under Henry II to serve as a wet nurse for the future monarch. As a result, Alexander was raised as Richard's foster-brother in their early years. Works ''Speculum speculationum'' The ''Speculum speculationum'' (edited by Rodney M. Thomson, 1988) is Neckam's major surviving contribution to the science of theology. It is unfinished in its current form, but covers a fairly standard range of theological topics derived from Peter Lombard's ''Sentences'' and Augustine. Neckam is not regarded as an especially innovative or profound theologian, although he is notable for his early interest in the ideas of St. Anselm of Canterbury. His outl ...

South-pointing Chariot
The south-pointing chariot (or carriage) was an ancient Chinese two-wheeled vehicle that carried a movable pointer to indicate the south, no matter how the chariot turned. Usually, the pointer took the form of a doll or figure with an outstretched arm. The chariot was supposedly used as a non-magnetic compass for navigation and may also have had other purposes. The ancient Chinese invented a mobile-like armored cart in the 5th century BC called the Dongwu Che (). It was used for the purpose of protecting warriors on the battlefield. The Chinese war wagon was designed as a kind of mobile protective cart with a shed-like roof. It would serve to be rolled up to city fortifications to provide protection for sappers digging underneath to weaken a wall's foundation. The early Chinese war wagon became the basis of technologies for the making of ancient Chinese south-pointing chariots. There are legends of earlier south-pointing chariots, but the first reliably documented one was creat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Technology Of The Song Dynasty
The Song dynasty (; 960–1279 CE) witnessed many substantial scientific and technological advances in Chinese history. Some of these advances and innovations were the products of talented statesmen and scholar-officials drafted by the government through imperial examinations. Shen Kuo (1031–1095), author of the ''Dream Pool Essays'', is a prime example, an inventor and pioneering figure who introduced many new advances in Chinese astronomy and mathematics, establishing the concept of true north in the first known experiments with the magnetic compass. However, commoner craftsmen such as Bi Sheng (972–1051), the inventor of movable type printing (in a form predating the printing press of Johannes Gutenberg), were also heavily involved in technical innovations. The ingenuity of advanced mechanical engineering had a long tradition in China. The Song engineer Su Song, who constructed a hydraulically-powered astronomical clocktower, admitted that he and his contemporaries ...

Chinese Literature
The history of Chinese literature extends thousands of years, and begins with the earliest recorded inscriptions, court archives, building to the major works of philosophy and history written during the Axial Age. The Han dynasty, Han (202 BC220 AD) and Tang dynasty, Tang (618–907 AD) dynasties were considered golden ages of poetry, while the Song dynasty, Song (960–1279) and Yuan dynasty, Yuan (1271–1368) were notable for their lyrics (''ci''), essays, dramas, and plays. During the Ming dynasty, Ming and Qing, mature novels were written in written vernacular Chinese, an evolution from the preeminence of Literary Chinese patterned off the language of the Chinese classics. The introduction of widespread woodblock printing during the Tang and the invention of movable type printing by Bi Sheng (990–1051) during the Song rapidly spread written knowledge throughout China. Around the turn of the 20th century, the author Lu Xun (1881–1936) is considered an influential voi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterproof
Waterproofing is the process of making an object, person or structure waterproof or water-resistant so that it remains relatively unaffected by water or resists the ingress of water under specified conditions. Such items may be used in wet environments or underwater to specified depths. ''Water-resistant'' and ''waterproof'' often refer to resistance to penetration of water in its liquid state and possibly under pressure, whereas '' damp proof'' refers to resistance to humidity or dampness. Permeation of water vapour through a material or structure is reported as a moisture vapor transmission rate (MVTR). The hulls of boats and ships were once waterproofed by applying tar or pitch. Modern items may be waterproofed by applying water-repellent coatings or by sealing seams with gaskets or o-rings. Waterproofing is used in reference to building structures (such as basements, decks, or wet areas), watercraft, canvas, clothing ( raincoats or waders), electronic devices and pape ...

Tang Dynasty
The Tang dynasty (, ; zh, c=唐朝), or the Tang Empire, was an Dynasties of China, imperial dynasty of China that ruled from 618 to 907, with an Wu Zhou, interregnum between 690 and 705. It was preceded by the Sui dynasty and followed by the Five Dynasties and Ten Kingdoms period. Historians generally regard the Tang as a high point in Chinese civilisation, and a Golden age (metaphor), golden age of cosmopolitan culture. Tang territory, acquired through the military campaigns of its early rulers, rivalled that of the Han dynasty.

Underwater
An underwater environment is a environment of, and immersed in, liquid water in a natural or artificial feature (called a Water, body of water), such as an ocean, sea, lake, pond, reservoir, river, canal, or aquifer. Some characteristics of the underwater environment are universal, but many depend on the local situation. Liquid water has been present on Earth for most of the History of Earth, history of the planet. The underwater environment is thought to be the place of the origin of life on Earth, and it remains the ecological region most critical to the support of life and the natural habitat of the majority of living organisms. Several branches of science are dedicated to the study of this environment or specific parts or aspects of it. A number of human activities are conducted in the more accessible parts of the underwater environment. These include research, underwater diving for work or recreation, and underwater warfare with submarines. It is hostile to humans in many ...
