Land Sailing
Land sailing, also known as sand yachting, land yachting or dirtboating, is the act of moving across land in a wheeled vehicle powered by wind through the use of a sail. The term comes from analogy with (water) sailing. Historically, land sailing was used as a mode of transportation or recreation. Since the 1950s, it has evolved primarily into a racing sport. Vehicles used in sailing are known as sail wagons, sand yachts, or land yachts. They typically have three (sometimes four) wheels and function much like a sailboat, except that they are operated from a sitting or lying position and steered by pedals or hand levers. Land sailing works best in windy flat areas, and races often happen on beaches, airfields, and dry lake beds in desert regions. Modern land sailors, generally known as "pilots", can go three to four times faster than the wind speed. A gust of wind is considered more beneficial in a land sailing race than a favorable windshift. A similar sport, known as ice yachti ...

Sail Wagon Edit1
A sail is a tensile structure—which is made from fabric or other membrane materials—that uses wind power to propel sailing craft, including sailing ships, sailboats, Windsurfing, windsurfers, ice boats, and even land sailing, sail-powered land vehicles. Sails may be made from a combination of woven materials—including canvas or polyester cloth, laminated membranes or bonded filaments—usually in a three- or four-sided shape. A sail provides propulsive force via a combination of lift and drag, depending on its angle of attack—its angle with respect to the apparent wind. Apparent wind is the air velocity experienced on the moving craft and is the combined effect of the true wind velocity with the velocity of the sailing craft. Angle of attack is often constrained by the sailing craft's orientation to the wind or point of sail. On points of sail where it is possible to align the leading edge of the sail with the apparent wind, the sail may act as an airfoil, generating p ...

Desert
A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to denudation. About one-third of the land surface of the Earth is arid or semi-arid. This includes much of the polar regions, where little precipitation occurs, and which are sometimes called polar deserts or "cold deserts". Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location. Deserts are formed by weathering processes as large variations in temperature between day and night put strains on the rocks, which consequently break in pieces. Although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods. Rain falling on hot rocks can cause them to shatter, and the resulting fragments and rubble strewn over the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hanfu
''Hanfu'' () is the traditional styles of clothing worn by the Han Chinese. There are several representative styles of ''hanfu'', such as the (an upper-body garment with a long outer skirt), the (an upper-body garment with a long underskirt), the and the , and the (an upper-body garment with ku trousers). Traditionally, ''hanfu'' consists of a ''paofu'' robe, or a ''ru'' jacket worn as the upper garment with a ''qun'' skirt commonly worn as the lower garment. In addition to clothing, hanfu also includes several forms of accessories, such as headwear, footwear, belts, jewellery, and handheld fans. Nowadays, the hanfu is gaining recognition as the traditional clothing of the Han ethnic group, and has experienced a growing fashion revival among young Han Chinese people in China and in the overseas Chinese diaspora. After the Han dynasty, ''hanfu'' developed into a variety of styles using fabrics that encompassed a number of complex textile production techniques, part ...

Silk
Silk is a natural protein fiber, some forms of which can be woven into textiles. The protein fiber of silk is composed mainly of fibroin and is produced by certain insect larvae to form cocoons. The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm ''Bombyx mori'' reared in captivity (sericulture). The shimmering appearance of silk is due to the triangular prism-like structure of the silk fibre, which allows silk cloth to refract incoming light at different angles, thus producing different colors. Silk is produced by several insects; but, generally, only the silk of moth caterpillars has been used for textile manufacturing. There has been some research into other types of silk, which differ at the molecular level. Silk is mainly produced by the larvae of insects undergoing complete metamorphosis, but some insects, such as webspinners and raspy crickets, produce silk throughout their lives. Silk production also occurs in hymenoptera ( bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Juan González De Mendoza
Juan González de Mendoza, O.S.A. (1545 – 14 February 1618) was a Spanish bishop, explorer, sinologist, and writer. He was the author of one of the earliest Western histories of China. Published by him in 1585, ''Historia de las cosas más notables, ritos y costumbres del gran reyno de la China'' (''The History of the Great and Mighty Kingdom of China and the Situation Thereof'') is an account of observations several Spanish travelers in China. An English translation by Robert Parke appeared in 1588 and was reprinted by the Hakluyt Society in two volumes, edited by Sir George T. Staunton, Bart. (London, 1853–54). González de Mendoza's ''Historia'' was mostly superseded in 1615 by the work of much more informed Jesuit missionaries who actually lived in China, Matteo Ricci and Nicolas Trigault, ''De Christiana expeditione apud Sinas''. Much of González de Mendoza's work was plagiarised from Escalante's ''Discurso de la navegacion'' Biography González de Mendoza was ...

Ming Dynasty
The Ming dynasty (), officially the Great Ming, was an Dynasties in Chinese history, imperial dynasty of China, ruling from 1368 to 1644 following the collapse of the Mongol Empire, Mongol-led Yuan dynasty. The Ming dynasty was the last orthodox dynasty of China ruled by the Han Chinese, Han people, the majority ethnic group in China. Although the primary capital of Beijing fell in 1644 to a rebellion led by Li Zicheng (who established the short-lived Shun dynasty), numerous rump state, rump regimes ruled by remnants of the House of Zhu, Ming imperial family—collectively called the Southern Ming—survived until 1662. The Ming dynasty's founder, the Hongwu Emperor (r. 1368–1398), attempted to create a society of self-sufficient rural communities ordered in a rigid, immobile system that would guarantee and support a permanent class of soldiers for his dynasty: the empire's standing army exceeded one million troops and the naval history of China, navy's dockyards in Nanjin ...

Two Methods Of Transportation In China
2 (two) is a number, numeral and digit. It is the natural number following 1 and preceding 3. It is the smallest and only even prime number. Because it forms the basis of a duality, it has religious and spiritual significance in many cultures. Evolution Arabic digit The digit used in the modern Western world to represent the number 2 traces its roots back to the Indic Brahmic script, where "2" was written as two horizontal lines. The modern Chinese and Japanese languages (and Korean Hanja) still use this method. The Gupta script rotated the two lines 45 degrees, making them diagonal. The top line was sometimes also shortened and had its bottom end curve towards the center of the bottom line. In the Nagari script, the top line was written more like a curve connecting to the bottom line. In the Arabic Ghubar writing, the bottom line was completely vertical, and the digit looked like a dotless closing question mark. Restoring the bottom line to its original horizontal ...

Emperor Yang Of Sui
Emperor Yang of Sui (隋煬帝, 569 – 11 April 618), personal name Yang Guang (), alternative name Ying (), Xianbei name Amo (), also known as Emperor Ming of Sui () during the brief reign of his grandson Yang Tong, was the second emperor of the Sui dynasty of China. Emperor Yang's original name was Yang Ying, but was renamed by his father, after consulting with oracles, to Yang Guang. Yang Guang was made the Prince of Jin after Emperor Wen established the Sui dynasty in 581. In 588, he was granted command of the five armies that invaded the southern Chen dynasty and was widely praised for the success of this campaign. These military achievements, as well as his machinations against his older brother Yang Yong, led to him becoming crown prince in 600. After the death of his father in 604, generally considered, though unproven, by most traditional historians to be a murder ordered by Yang Guang, he ascended the throne as Emperor Yang.

Emperor Yuan Of Liang
Emperor Yuan of Liang () (16 September 508 – 27 January 555), personal name Xiao Yi (), courtesy name Shicheng (), childhood name Qifu (), was an emperor of the Chinese Liang Dynasty. After his father Emperor Wu and brother Emperor Jianwen were successively taken hostage and controlled by the rebel general Hou Jing, Xiao Yi was largely viewed as the ''de facto'' leader of Liang, and after defeating Hou in 552 declared himself emperor. In 554, after offending Yuwen Tai, the paramount general of rival Western Wei, Western Wei forces descended on and captured his capital Jiangling (江陵, in modern Jingzhou, Hubei), executing him and instead declaring his nephew Xiao Cha (Emperor Xuan) the Emperor of Liang. Emperor Yuan was a renowned writer and collector of ancient books, but was criticized by historians for concentrating on eliminating potential contenders for the throne rather than on fighting Hou Jing. As Jiangling was besieged by Western Wei troops, Emperor Yuan set his c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crown Prince
A crown prince or hereditary prince is the heir apparent to the throne in a royal or imperial monarchy. The female form of the title is crown princess, which may refer either to an heiress apparent or, especially in earlier times, to the wife of the person styled crown prince. ''Crown prince'' as a descriptive term has been used throughout history for the prince who is first-in-line to a throne and is expected to succeed (i.e. the heir apparent), barring any unforeseen future event preventing this. In certain monarchies, a more specific substantive title A substantive title is a title of nobility or royalty acquired either by individual grant or inheritance. It is to be distinguished from a title shared among cadets, borne as a courtesy title by a peer's relatives, or acquired through marriage. ... may be accorded and become associated with the position of '' heir apparent'' (e.g. Prince of Wales in the United Kingdom or Prince of Asturias in the Spain, Kingdom of Spain) ...

Mast (sailing)
The mast of a sailing vessel is a tall spar, or arrangement of spars, erected more or less vertically on the centre-line of a ship or boat. Its purposes include carrying sails, spars, and derricks, and giving necessary height to a navigation light, look-out position, signal yard, control position, radio aerial or signal lamp. Large ships have several masts, with the size and configuration depending on the style of ship. Nearly all sailing masts are guyed. Until the mid-19th century, all vessels' masts were made of wood formed from a single or several pieces of timber which typically consisted of the trunk of a conifer tree. From the 16th century, vessels were often built of a size requiring masts taller and thicker than could be made from single tree trunks. On these larger vessels, to achieve the required height, the masts were built from up to four sections (also called masts). From lowest to highest, these were called: lower, top, topgallant, and royal masts. Giving the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
