Sino-Swedish Expedition
The Sino-Swedish Expedition was a bilateral Chinese-Swedish expedition, led by Sven Hedin, which carried out scientific research in north and northwest China, 1927–1935. About the Expedition The Expedition looked in particular at the meteorology, topography and prehistory in Mongolia, the Gobi Desert and Xinjiang. Chiang Kai-shek was a patron of the Expedition. * 1927–32 – from Beijing – via Baotou, Mongolia, the Gobi Desert, Xinjiang – to Urumqi * 1933–34 – from Beijing to Kashgar, with a view to constructing two roads suitable for cars Between 1927 and 1935, Hedin led an international Sino-Swedish Expedition which investigated the meteorological, topographic and prehistoric situation in Mongolia, the Gobi Desert and Xinjiang. Hedin described it as a peripatetic university in which the participating scientists worked almost independently, while he—like a local manager—negotiated with local authorities, made decisions, organized whatever was necessary, raised f ...

Palace Museum
The Palace Museum () is a huge national museum complex housed in the Forbidden City at the core of Beijing, China. With , the museum inherited the imperial royal palaces from the Ming and Qing dynasties of China and opened to the public in 1925 after the last Emperor of China was evicted. Constructed from 1406 to 1420, the museum consists of 980 buildings. It is home to over 1.8 million pieces of art, mostly from the imperial collection of the Ming and Qing dynasties. The 20th century saw its expansion through new acquisitions, transfers from other museums, and new archaeological discoveries. According to the ''Beijing Evening Post'', the museum has seen more than 17 million visitors in 2018, which would make it the world's most visited museum. It has an average of 15 million visitors annually since 2012. Due to this increased pressure, the management has set a daily limit for visitors of 80,000 since 2015 to protect the structure and the experience. History Palace Th ...

Antarctic
The Antarctic ( or , American English also or ; commonly ) is a polar region around Earth's South Pole, opposite the Arctic region around the North Pole. The Antarctic comprises the continent of Antarctica, the Kerguelen Plateau and other island territories located on the Antarctic Plate or south of the Antarctic Convergence. The Antarctic region includes the ice shelves, waters, and all the island territories in the Southern Ocean situated south of the Antarctic Convergence, a zone approximately wide varying in latitude seasonally. The region covers some 20 percent of the Southern Hemisphere, of which 5.5 percent (14 million km2) is the surface area of the Antarctica continent itself. All of the land and ice shelves south of 60°S latitude are administered under the Antarctic Treaty System. Biogeographically, the Antarctic realm is one of eight biogeographic realms of Earth's land surface. Geography As defined by the Antarctic Treaty System, the Antarctic r ...

Gauss Expedition
The ''Gauss'' expedition of 1901–1903 (also known as the ''Deutsche Südpolar-Expedition 1901–1903)'' was the first German expedition to Antarctica. It was led by geologist Erich von Drygalski in the ship , named after the mathematician and physicist Carl Friedrich Gauss. Voyage Drygalski led the first German South Polar expedition with the ship ''Gauss'' to explore the unknown area of Antarctica lying south of the Kerguelen Islands. The expedition started from Kiel on 11 August 1901. Expedition A small party of the expedition was also stationed on the Kerguelen Islands, while the main party proceeded further south. Erich von Drygalski paid a brief call to Heard Island and provided the first comprehensive scientific information on the island's geology, flora, and fauna. Despite their entrapment in the ice for nearly 14 months (until February 1903), new territory was discovered: Kaiser Wilhelm II Land and its volcano—Gaussberg. Drygalski was the first to use a ...

Gold
Gold is a chemical element with the symbol Au (from la, aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental ( native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Gold is ...

Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some iron ...

Manganese
Manganese is a chemical element with the symbol Mn and atomic number 25. It is a hard, brittle, silvery metal, often found in minerals in combination with iron. Manganese is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels. It improves strength, workability, and resistance to wear. Manganese oxide is used as an oxidising agent; as a rubber additive; and in glass making, fertilisers, and ceramics. Manganese sulfate can be used as a fungicide. Manganese is also an essential human dietary element, important in macronutrient metabolism, bone formation, and free radical defense systems. It is a critical component in dozens of proteins and enzymes. It is found mostly in the bones, but also the liver, kidneys, and brain. In the human brain, the manganese is bound to manganese metalloproteins, most notably glutamine synthetase in astrocytes. Manganese was first isolated in 1774. It is familiar in the laboratory in the form of the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Iron
Iron () is a chemical element with symbol Fe (from la, ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, right in front of oxygen (32.1% and 30.1%, respectively), forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. In its metallic state, iron is rare in the Earth's crust, limited mainly to deposition by meteorites. Iron ores, by contrast, are among the most abundant in the Earth's crust, although extracting usable metal from them requires kilns or furnaces capable of reaching or higher, about higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BCE and the use of iron tools and weapons began to displace copper alloys, in some regions, only around 1200 BCE. That event is considered the transition from the Bronze Age to the Iron A ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
